SUMMARY OF PRINCIPAL RISKS ASSOCIATED WITH OUR BUSINESS

Our business is subject to numerous risks and uncertainties, including those described in Part I, Item 1A, “Risk Factors” in this Annual Report on Form 10-K. You 
should carefully consider these risks and uncertainties when investing in our securities. The principal risks and uncertainties affecting our business include the 
following:

•

•

•

We are an early-stage biopharmaceutical company with a limited operating history and no products approved for commercial sale. We have incurred 
significant losses since our inception, and we anticipate that we will continue to incur significant losses for the foreseeable future, which, together with 
our limited operating history, makes it difficult to assess our future viability;

We are very early in our development efforts. Our business is dependent on the successful development of our product candidates, future product 
candidates, and companion diagnostics for biomarkers associated with our product candidates and future product candidates;

In connection with the Collaboration, Option and License Agreement with GSK, if GSK terminates any development program under its collaborations 
with us, whether as a result of our inability to meet milestones or 

iii

 
otherwise, any potential revenue from those collaborations will be significantly reduced or eliminated, and our results of operations and financial 
condition will be materially and adversely affected;

As an organization, we have never completed a clinical trial, and may be unable to do so for any of our product candidates;

The successful development of targeted therapeutics, including therapeutics involving direct targeting of an oncogenic pathway and synthetic lethality 
therapeutics, including our portfolio of synthetic lethality small molecule inhibitors, as well as any related diagnostics, is highly uncertain;

Preclinical and clinical drug development is a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience 
delays in completing, or ultimately be unable to complete, the development and commercialization of any product candidates, which could result in 
increased costs to us, delay or limit our ability to generate revenue and adversely affect our business, financial condition, results of operations and 
prospects. Furthermore, results of earlier studies and trials may not be predictive of future trial results;

We may find it difficult to enroll patients in our clinical trials given the limited number of patients who have the diseases for which our product 
candidates are being developed. If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed 
or otherwise adversely affected;

If we are unable to successfully develop molecular diagnostics for biomarkers that enable patient selection and/or that demonstrate drug-target 
interaction, or experience significant delays in doing so, we may not realize the full commercial potential of our product candidates;

We rely on third parties for the manufacture of our product candidates for preclinical and clinical development and expect to continue to do so for the 
foreseeable future. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or 
such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts;

We face significant competition in an environment of rapid technological and scientific change, and our failure to effectively compete may prevent us 
from achieving significant market penetration. Most of our competitors have significantly greater resources than we do and we may not be able to 
successfully compete;

If we fail to attract and retain senior management and key scientific personnel, our business may be materially and adversely affected;

Our success depends on our ability to obtain and maintain protection for our intellectual property and our proprietary technologies, to successfully 
enforce our intellectual property rights and to avoid infringing the rights of others; and 

Our stock price has been and may continue to be volatile and you may not be able to resell shares of our common stock at or above the price you paid.

Company Overview 

PART I

We are a precision medicine oncology company committed to the discovery and development of targeted therapeutics for patient populations selected using molecular 
diagnostics. Our clinical pipeline includes four potential first-in-class clinical-stage product candidates – darovasertib (PKC), IDE397 (MAT2A), IDE161 (PARG) and 
GSK101 (Pol Theta Helicase). We own or control all commercial rights of the three most-advanced of these product candidates: darovasertib, IDE397, and IDE161. We 
are also advancing our Werner Helicase program for which we have selected a development candidate in collaboration with GlaxoSmithKline, or GSK and, subject to 
investigational new drug-, or IND-, enabling studies, are targeting an IND in 2024. We also have multiple earlier-stage preclinical programs. We have established 
selective, value-accretive collaborations with leading pharmaceutical companies to support our clinical development activities.

Our most advanced clinical program is evaluating darovasertib, or IDE196 which we in-licensed from Novartis, a small molecule protein kinase C, or PKC, inhibitor, in 
uveal melanoma, or UM. We have initiated a potential registration-enabling Phase 2/3 clinical trial, designated as IDE196-002, to evaluate darovasertib in combination 
with crizotinib, Pfizer’s investigational cMET inhibitor, in patients having metastatic UM, or MUM, with human leukocyte antigen-, or HLA-A*02:01 negative, or 
HLA-A2(-), serotype, as part of a second Clinical Trial Collaboration and Supply Agreement, or Second Pfizer agreement, with Pfizer. We have achieved double-digit 
patient enrollment and have opened multiple clinical sites, including international sites, where we are recruiting patients for enrollment in this planned global Phase 2/3 
clinical trial. We reported positive interim clinical data in April 2023 from our Phase 2 clinical trial evaluating darovasertib and crizotinib in MUM. We also reported 
updated darovasertib clinical top line results, circulating tumor DNA, or ctDNA, data and HLA-A2(-)/(+) data subsets from this Phase 2 clinical trial, as well as HLA-
A2(-)/(+) prevalence based on our broader clinical experience in MUM, at the European Society for Medical Oncology’s Congress in October 2023, or ESMO 2023. 
We are targeting clinical program update(s) in 2024. 

We are also planning to enroll additional HLA-A*02:01 positive, or HLA-A2(+), patients as an independent clinical strategy to address HLA-A2(+) MUM patients, in a 
clinical study. This strategy reflects observed darovasertib clinical activity irrespective of HLA serotype as reported at ESMO 2023, and demonstrates our commitment 
to fully address the high unmet medical need in MUM. We are further evaluating darovasertib in combination with crizotinib in a Phase 2 expansion arm of IDE196-
001 clinical trial in patients with cutaneous melanoma, alternatively referred to as skin melanoma.

We separately initiated and have achieved double-digit patient enrollment in our Phase 2 clinical trial, designated as IDE196-009, evaluating darovasertib as single-
agent neoadjuvant and adjuvant therapy in patients having primary UM, with ongoing enrollment and multiple clinical sites open, and are targeting a clinical efficacy 
update in mid-year 2024 and regulatory guidance update in 2024. We are also supporting evaluation of darovasertib as single-agent neoadjuvant and adjuvant therapy in 
primary UM in an ongoing investigator-sponsored clinical trial, or IST, captioned as “Neoadjuvant / Adjuvant trial of Darovasertib in Ocular Melanoma”, or NADOM, 
and led by St. Vincent’s Hospital in Sydney with the participation of Alfred Health and the Royal Victorian Eye and Ear Hospital in Melbourne and are targeting a 
clinical efficacy update in mid-year 2024. We reported proof-of-concept evidence in April 2023, June 2023 and October 2023 for darovasertib as neoadjuvant therapy in 
primary UM.

IDE397, our small molecule methionine adenosyltransferase 2a, or MAT2A, inhibitor, is being evaluated in a Phase 1/2 clinical trial. We are actively enrolling into the 
Phase 2 monotherapy expansion cohort in selected priority indications for patients having tumors with methylthioadenosine phosphorylase, or MTAP, gene deletion, 
including squamous non-small cell lung cancer, or NSCLC, bladder, gastric and esophageal cancers. We observed IDE397 monotherapy responses in multiple priority 
solid tumor types based on experience across several patients in the early phase of the Phase 2 dose expansion.

In collaboration with Amgen as part of the Amgen Clinical Trial Collaboration and Supply Agreement, or Amgen CTCSA, we initiated patient enrollment in the 
Amgen-sponsored Phase 1/2 clinical trial evaluating IDE397 in combination with AMG 193, the Amgen investigational MTA-cooperative protein arginine 
methyltransferase 5, or PRMT5, inhibitor, in patients having tumors with MTAP deletion, or the IDE397/AMG 193 combination study. This potential first-in-class 
synthetic lethality 

1

 
 
 
 
 
 
 
combination targets mechanistically complementary nodes of the MTAP methylation pathway – MAT2A and PRMT5 – and is supported by data demonstrating 
preclinical anti-tumor efficacy presented at the 2023 Annual Meeting of the American Association for Cancer Research, or AACR 2023.

We are also planning to evaluate IDE397 in combination with sacituzumab-govitecan-hziy, or Trodelvy, Gilead’s Trop-2 directed anti-body conjugate, or ADC, in 
patients having MTAP deletion bladder cancer, in an IDEAYA-sponsored clinical trial pursuant to a Clinical Study Collaboration and Supply Agreement, or Gilead 
CSCSA, with Gilead Sciences, Inc., or Gilead. 

IDE161, our small molecule poly (ADP-ribose) glycohydrolase, or PARG, inhibitor, is being evaluated in a Phase 1 clinical trial, which is currently in monotherapy 
expansion, with a strategic focus in estrogen receptor positive, or ER+, human epidermal growth factor receptor 2 negative, or Her2(-),breast cancer with homologous 
recombination deficiency, or HRD, as well as other solid tumors with HRD, such as endometrial cancer, colorectal cancer and prostate cancer. We are, in parallel, 
continuing with Phase 1 dose optimization of IDE161 in patients having tumors with HRD. We have observed multiple partial responses, or PRs, by RECIST 1.1. and 
tumor shrinkage in priority solid tumor types early in the Phase 1 dose escalation and at the expansion dose. We received Fast Track Designation from the U.S. Food 
and Drug Administration, or FDA, for IDE161 for ovarian cancer and breast cancer indications, specifically for the treatment of (i) adult, pretreated, platinum-resistant 
advanced or metastatic ovarian cancer patients having tumors with BRCA1/2 mutations and (ii) adult, pretreated, advanced or metastatic hormone receptor positive, or 
HR+, Her2- and BRCA1/2 mutant breast cancer patients.

GSK101 (IDE705), our Pol Theta Helicase inhibitor, is a potential first-in-class small molecule inhibitor of the helicase domain of Polymerase Theta, or Pol Theta. 
GSK101 was discovered and evaluated in preclinical studies in collaboration with GSK. GSK is evaluating GSK101 in a GSK-sponsored clinical trial in combination 
with niraparib, the GSK small molecule inhibitor of poly-(ADP-ribose) polymerase, or PARP, for the treatment of patients having tumors with BRCA or other 
homologous recombination, or HR, mutations, or HRD. GSK has dosed the first patient in this Phase 1 clinical trial.

GSK is leading clinical development for GSK101 and is responsible for all research and development costs for the Pol Theta program. In August 2023, we earned, and 
in October 2023 we received, a $7.0 million milestone payment upon acceptance of the IND for GSK101 by the FDA. We are next eligible to receive a potential 
additional $10.0 million milestone payment upon initiation of Phase 1 clinical dose expansion.

We have selected a Werner Helicase Inhibitor Development Candidate, or DC, in collaboration with GSK. This Werner Helicase Inhibitor DC is targeting the helicase 
domain of the Werner, or WRN, protein, for patients having tumors with high microsatellite instability, or MSI. In October 2023, we earned a $3.0 million milestone 
from GSK in connection with IND-enabling studies for the Werner Helicase Inhibitor DC. We are, in collaboration with GSK, targeting an IND submission in 2024 to 
enable first-in-human clinical evaluation of our Werner Helicase Inhibitor DC in high MSI tumors. We are next eligible to receive a potential additional $7.0 million 
milestone payment upon IND clearance for the Werner Helicase Inhibitor DC.

We have multiple wholly owned preclinical-stage programs on undisclosed targets to enable the next wave of precision medicine therapeutics in our pipeline. These 
preclinical programs are focused on opportunities that we believe have the potential to be first-in-class and/or best-in-class. We are targeting multiple DC nominations 
for these programs in 2024.

We have established a robust precision medicine research platform with capabilities for identification and validation of new targets and biomarkers, drug discovery and 
translational biology. Our approach integrates small molecule drug discovery with extensive capabilities in identifying and validating translational biomarkers to 
develop targeted therapies for select patient populations that are most likely to benefit from these targeted therapies. Our small molecule drug discovery expertise 
includes discovery and development of small molecule therapeutics. The drug discovery platform includes our proprietary chemical library, INQUIRE™, structure-
based drug design enabled by extensive structural biology and crystallography capabilities, and our proprietary content-based machine-learning engine, HARMONY™, 
providing effective and efficient molecular design and structure-activity-relationship, or SAR, cycles. We have deep research and development expertise in synthetic 
lethality—which represents an emerging class of precision medicine targets. We are applying these capabilities to develop a robust pipeline in precision medicine 
oncology.

2

 
 
 
 
 
 
 
 
 
We have assembled a team of cancer biologists, drug discovery chemists, translational biologists and drug development professionals with broad experience at leading 
oncology organizations. Our team is led by our Chief Executive Officer, Yujiro S Hata. We are also guided by a renowned scientific advisory board made up of key 
scientific and clinical thought leaders. 

Strategy 

Our objective is to develop and commercialize innovative precision medicine drugs that indirectly or directly target the genetic drivers of cancer in order to provide 
therapies for defined patient populations. The principal components of our strategy are to: 

Continue to efficiently develop our clinical-stage product candidates, darovasertib, IDE397, IDE161, and GSK101. We are evaluating darovasertib in combination with 
crizotinib in a potential registrational clinical trial in patients having MUM. We are also evaluating darovasertib as monotherapy in a Phase 2 clinical trial in primary 
UM. We are further evaluating darovasertib in combination with crizotinib in a Phase 2 clinical trial in patients with cutaneous melanoma. We are currently evaluating 
IDE397 in a Phase 2 monotherapy expansion cohort in selected priority indications for patients having tumors with MTAP gene deletion, including NSCLC, bladder, 
gastric and esophageal cancers. We are currently evaluating IDE161 in a Phase 1 expansion trial in homologous recombination deficiency, or HRD, solid tumor types, 
including ER+ HER- breast, colorectal, endometrial, and prostate cancers. We received Fast Track Designation from the FDA for IDE161 for ovarian cancer and breast 
cancer indications, specifically for the treatment of (i) adult, pretreated, platinum-resistant advanced or metastatic ovarian cancer patients having tumors with BRCA1/2 
mutations and (ii) adult, pretreated, advanced or metastatic hormone receptor positive, or HR+, Her2- and BRCA1/2 mutant breast cancer patients.

Advance our preclinical pipeline of small molecule product candidates in synthetic lethality into clinical development. Our synthetic lethality pipeline includes multiple 
preclinical research programs, including our Werner Helicase program. We have selected a development candidate in collaboration with GSK and, subject to IND-
enabling studies, are targeting an IND submission in 2024. We are also continuing to invest in our earlier-stage pre-clinical programs and have established selective, 
value-accretive collaborations with leading pharmaceutical companies to support our clinical development activities. 

Broaden our pipeline of targeted therapies and apply our core capabilities to establish a leading franchise in the field of synthetic lethality. We are continuing our target 
identification and validation activities for advancing new synthetic lethality targets and associated biomarkers, with active programs for several next-generation 
synthetic lethality targets. We continue to invest in core functional capabilities, including in drug discovery, bioinformatics and translational biology. 

Collaborate with leaders in the field of diagnostics to enable the identification of defined patient populations for our product candidates. Our precision medicine 
approach leverages the availability or development of companion diagnostics to identify patients for which our product candidates will be most effective.

Collaborate under our existing strategic partnerships and identify additional strategic collaborations to accelerate development timelines and maximize the commercial 
potential of our targeted product candidates. We have entered into the Pfizer Agreements for evaluation of the darovasertib in combination with crizotinib in MUM and 
cutaneous melanoma. We entered into the Amgen CTCSA to clinically evaluate IDE397 in combination with AMG 193, the Amgen investigational MTA-cooperative 
PRMT5 inhibitor, in patients having MTAP-deletion solid tumors. We have entered into the Gilead CSCSA to clinically evaluate IDE397 in combination with 
sacituzumab-govitecan-hziy (Trodelvy), Gilead's Trop-2 directed ADC, in patients having MTAP-deletion bladder cancer. We have entered into a strategic partnership 
and collaboration with GSK for our synthetic lethality programs targeting Pol Theta and Werner Helicase pursuant to the Collaboration, Option and License Agreement 
with GSK, or GSK Collaboration Agreement. We will selectively evaluate strategic collaborations for our targeted product candidates with biopharmaceutical partners 
whose research, development, commercial, marketing, and geographic capabilities complement our own.

All data and the status of each program are as of February 1, 2024, unless otherwise noted.

Darovasertib - (GNAQ or GNA11 Mutations)

•

•

•

•

•

We are evaluating darovasertib in combination with crizotinib, an investigational cMET inhibitor in a potential registrational clinical trial in patients 
having MUM. We have initiated a potential registration-enabling Phase 2/3 clinical trial to evaluate the darovasertib and crizotinib combination in MUM 
patients with human leukocyte antigen-, or HLA-A*02:01 negative, or HLA-A2(-), serotype. We have achieved double-digit patient enrollment and have 
opened multiple clinical sites, including international sites, where we are recruiting patients for enrollment in this planned global Phase 2/3 clinical trial. 
We are targeting clinical program update(s) in 2024.

We are planning to enroll additional HLA-A*02:01 positive, or HLA-A2(+), patients as an independent clinical strategy to address HLA-A2(+) MUM 
patients, in a clinical study.

We have initiated a Phase 2 expansion arm in our IDE196-001 clinical trial evaluating the darovasertib and crizotinib combination in GNAQ/11 
metastatic cutaneous melanoma, based on the observed preliminary clinical efficacy.

We separately initiated and have achieved double-digit patient enrollment in our Phase 2 clinical trial evaluating darovasertib as single-agent 
neoadjuvant and adjuvant therapy in patients having primary UM, with ongoing enrollment and multiple clinical sites open, and are targeting a clinical 
efficacy update in mid-year 2024 and regulatory guidance update in 2024. We are also supporting evaluation of darovasertib as single-agent neoadjuvant 
and adjuvant therapy in primary UM in an ongoing investigator-sponsored clinical trial, or IST, captioned as “Neoadjuvant / Adjuvant trial of 
Darovasertib in Ocular Melanoma”, or NADOM, and led by St. Vincent’s Hospital in Sydney with the participation of Alfred Health and the Royal 
Victorian Eye and Ear Hospital in Melbourne and are targeting a clinical efficacy update in mid-year 2024.

We own or control all commercial rights in our darovasertib program in uveal melanoma, including in MUM and in primary UM, subject to certain 
economic obligations pursuant to our exclusive, worldwide license to darovasertib with Novartis.

IDE397 (MTAP Gene Deletion)

•

•

•

•

•

•

We are enrolling patients into a Phase 2 clinical trial designated as IDE397-001 to evaluate IDE397 for patients having certain tumors with MTAP gene 
deletion.

We are proceeding with enrollment of MTAP-deletion patients into a monotherapy Phase 2 expansion cohort with an initial focus on high priority solid 
tumor types, including squamous NSCLC, bladder, esophageal and gastric cancers. 

In June 2023, we announced selection of a Phase 2 monotherapy expansion dose for IDE397 and in connection therewith, reported preliminary evidence 
of clinical activity as monotherapy.

We are collaborating with Amgen to clinically evaluate IDE397 in combination with AMG 193, the Amgen investigational MTA-cooperative PRMT5 
inhibitor, in patients having tumors with MTAP deletion, in an Amgen-sponsored clinical trial pursuant to the Amgen CTCSA.

In April 2023, we co-presented preclinical efficacy data with Amgen at the 2023 Annual Meeting of the American Association for Cancer Research, or 
AACR 2023, for the IDE397 and AMG 193 combination in a NSCLC MTAP-null cell-derived xenograft, or CDX, model. The data collectively 
demonstrates that combined pharmacological inhibition of MAT2A and PRMT5 deepens the biological response through maximal pathway suppression.

In August 2023, Amgen initiated and dosed a first patient in the IDE397 /AMG 193 combination study, following clearance of the Amgen-sponsored 
IND and FDA authorization to proceed with the clinical trial. This Phase 1/2 clinical trial will evaluate the safety, tolerability, pharmacokinetics, 
pharmacodynamics and efficacy of IDE397 in combination with AMG 193, with an initial focus for expansion in NSCLC patients and an estimated 
enrollment of approximately 180 patients. We are targeting the development of a joint publication strategy in 2024.

•

We are collaborating with Gilead to clinically evaluate IDE397 in combination with Trodelvy, the Gilead Trop-2 directed ADC, in patients having 
MTAP deletion bladder cancer, in an IDEAYA-sponsored clinical trial pursuant to the Gilead CSCSA. We anticipate enrolling the first patient in this 
clinical trial in mid-year 2024.

We own all right, title and interest in and to IDE397 and the MAT2A program, including all worldwide commercial rights thereto.

PARG Program (HRD, including BRCA)

•

•

•

•

•

We are progressing with enrollment of patients having tumors with HRD into the Phase 1 expansion portion of the Phase 1/2 clinical trial in selected 
priority tumors. In parallel, we are also continuing with Phase 1 dose optimization to confirm a move-forward expansion dose for the planned Phase 2 
portion of the clinical trial. We are targeting clinical program update(s) in 2024. We are also validating IDE161 combination opportunities preclinically 
and targeting identification of potential combination(s) in 2024. 

In connection with the Phase 1 expansion announced in September 2023, we disclosed preliminary clinical proof-of-concept for IDE161 in HRD solid 
tumors based on early clinical data from the dose escalation cohorts. These clinical data showed dose-dependent pharmacodynamic modulation of poly-
ADP ribose (PAR) proteins in peripheral blood, demonstrating IDE161 target engagement. In addition, we announced a greater than 50% PSA reduction 
in a prostate cancer patient in January 2023.

In September 2023, we received Fast Track Designation from the FDA for IDE161 for ovarian cancer and breast cancer indications, specifically for the 
treatment of (i) adult, pretreated, platinum-resistant advanced or metastatic ovarian cancer patients having tumors with BRCA1/2 mutations and (ii) 
adult, pretreated, advanced or metastatic hormone receptor positive, or HR+, Her2- and BRCA1/2 mutant breast cancer patients.

The expansion portion of the Phase 1 trial will include HRD solid tumor types, including endometrial, colorectal, prostate, and ER+ HER2- breast 
cancers.

We are targeting IDE161 clinical program update(s) and enabling clinical combination(s) in 2024. 

Pol Theta Program (HR mutations, including BRCA, or HRD)

•

•

•

•

In November 2023, GSK initiated and dosed a first patient in the Phase 1 clinical trial for GSK101, following submission of the GSK-sponsored IND 
and FDA allowance to proceed with the clinical trial. GSK intends to clinically evaluate GSK101 in combination with niraparib, the GSK small 
molecule inhibitor of PARP for the treatment of patients having tumors with BRCA or other HRD.

GSK is leading clinical development of GSK101 pursuant to the GSK Collaboration Agreement.

In August 2023, we earned and in October 2023 we received a $7.0 million payment for a milestone based on acceptance of the IND by the FDA.

We have the potential to receive an additional $10.0 million milestone payment upon initiation of Phase 1 clinical dose expansion. 

WRN Program (High MSI)

•

•

•

We selected a Werner Helicase Inhibitor DC in collaboration with GSK. Subject to successful completion of ongoing IND-enabling studies, we are 
targeting an IND submission in 2024 to enable first-in-human clinical evaluation of Werner Helicase Inhibitor DC for patients having tumors with high 
MSI.

We are collaborating with GSK on the ongoing IND-enabling studies and, subject to IND submission and FDA allowance to proceed with clinical 
development, GSK will lead clinical development for the Werner Helicase program.

In October 2023, we earned a $3 million milestone in connection with IND-enabling studies. We have the potential to earn up to an additional $17 
million aggregate milestone payments through early Phase 1 clinical studies, including $7.0 million upon IND clearance.

Other Pipeline Programs (Defined Biomarkers)

•

•

•

We have initiated early preclinical research programs focused on pharmacological inhibition of several new targets, or NTs, for patients with solid 
tumors characterized by defined biomarkers based on genetic mutations and/or molecular signatures. We believe these research programs have the 
potential for discovery and development of first-in-class or unique-in-class or best-in-class therapeutics.

We are targeting development candidate nominations in 2024 for multiple NTs, including a development candidate to treat MTAP-deletion solid tumors.

We own or control all commercial rights in our next-generation programs. 

New Target and Biomarker Discovery Platform

•

•

We have invested significantly and continue to invest in capabilities for identification and validation of new precision medicine targets and biomarkers 
for patient selection. For targets of interest, we advance our research to discover therapeutic drugs and to further qualify relevant biomarkers.

We own or control all commercial rights in programs directed to targets identified in on our new target and biomarker discovery platform.

Scientific Rationale – Synthetic Lethality 

Synthetic lethality is emerging as an important therapeutic paradigm in the treatment of cancer. It was first defined by Calvin Bridges in 1922 based on the observation 
that certain combinations of gene mutations resulted in lethality despite the fact the single mutations in either gene were viable. 

Cancer cells often contain genetic changes that lead to alterations in pathways such as DNA repair and metabolism. These changes endow the cancer cells with certain 
properties such as the ability to replicate by bypassing normal control mechanisms. However, removing these important regulators of cell function may also make these 
cancer cells more dependent on backup pathways that can then be targeted to achieve a therapeutic effect. We are using small molecule inhibitors against targets in 
DNA damage repair, or DDR, pathways or in tumor metabolism pathways, that have potentially less effects on the viability of normal cells, but are designed to result in 
lethality in cancer cells having specific underlying genetic alterations. Cancer targets based on synthetic lethality are ideal for precision medicine approaches because 
each product candidate inherently has a tumor-associated genetic biomarker to facilitate patient selection.

Darovasertib – PKC Inhibitor Clinical Candidate in Uveal Melanoma

Darovasertib (IDE196) is our most advanced clinical-stage product candidate. Darovasertib is a potent, selective small molecule inhibitor of PKC, which we are 
developing for genetically-defined cancers having GNAQ or GNA11 gene mutations. PKC is a protein kinase that functions downstream of the GTPases GNAQ and 
GNA11. 

We are pursuing a clinical strategy for darovasertib to broadly address uveal melanoma, alternatively referred to as ocular melanoma, as both primary and metastatic 
disease. Greater than 90% of uveal melanoma patients have tumors harboring GNAQ or GNA11 mutations. There are no FDA approved systemic therapies for primary 
UM, as either neoadjuvant or adjuvant therapies. There are likewise no FDA approved therapies for patients having MUM with HLA-A*02:01 negative, or HLA-A2(-), 
serotype. These primary UM patients and HLA-A2(-) MUM patients collectively represent approximately 85% of all ocular melanoma patients. We have a separate, 
independent clinical strategy to address HLA-A*02:01 positive, or HLA-A2(+), MUM patients.

The potentially addressable patient population for MUM is estimated to include an annual incidence of approximately 4,500 patients across the United States, or U.S., 
and Europe, with an estimated total prevalence of approximately 14,000 patients in the U.S. and Europe. (Neo)Adjuvant UM represents a significant expansion 
opportunity for darovasertib – with a potential annual incidence of approximately 8,700 patients aggregate in U.S. and Europe and with an estimated total prevalence of 
approximately 100,000 patients in the U.S. and Europe.

obligations pursuant to our exclusive, worldwide license to darovasertib with Novartis.

Darovasertib – Potential Registration-Enabling Clinical Trial in First-Line HLA-A2(-) Metastatic Uveal Melanoma

We have achieved double-digit patient enrollment and have opened multiple clinical sites, including international sites, where we are recruiting patients for enrollment 
in our potentially registration-enabling Phase 2/3 clinical trial, designated as IDE196-002, to evaluate darovasertib and crizotinib as a combination therapy in HLA-
A2(-) MUM. We are the sponsor of this registrational Phase 2/3 clinical trial and are also collaborating with Pfizer for supply of crizotinib on this Phase 2/3 
registrational trial, pursuant to the Second Pfizer Agreement. We are targeting clinical program update(s) in 2024.

The protocol of the Phase 2/3 clinical trial design incorporates guidance and feedback following our Type C meeting with the FDA in March 2023. This protocol 
includes an integrated Phase 2/3 open-label study-in-study design in first-line MUM patients with an HLA-A2(-) serotype. The clinical trial design employs a Phase 2 
portion with median progression free survival, or PFS, as a primary endpoint for potential accelerated approval. Patients enrolled in Phase 2 will continue on treatment 
within the same study and will be considered, together with additional enrolled patients, to evaluate overall survival, or OS, as the primary endpoint of the Phase 3 
portion of the clinical trial to support a potential confirmational approval.

In the Phase 2 portion of the clinical trial, approximately 230 patients will be randomized on a 2:1 basis for treatment with the darovasertib and crizotinib combination 
in the treatment arm or investigators choice in the control arm, selected from (a) a combination of ipilimumab (ipi) and nivolumab (nivo), (b) PD1-targeted 
monotherapy or (c) dacarbazine. The treatment arm of the Phase 2 portion of the clinical trial includes a nested study to confirm the move forward combination dose for 
the integrated Phase 2/3 clinical trial – including cohorts at the Phase 2 expansion doses of (i) darovasertib 300 mg BID + crizotinib 200 mg BID and (ii) darovasertib 
200 mg BID + crizotinib 200 mg BID. Under the nested study design, patients enrolled in the cohort at the move forward dose will be included within the Phase 2/3 
registrational clinical trial. The Phase 2 portion of the clinical trial contemplates an efficacy and safety data set of approximately 200 patients randomized 2:1 with the 
treatment arm at the move forward dose to support a potential accelerated approval based on median PFS by blinded independent central review, or BICR, as a primary 
endpoint. Accelerated approval is intended to allow for earlier approval of drugs that treat serious conditions and fill an unmet medical need based on a demonstration 
of effectiveness on a surrogate endpoint.

Patients enrolled in Phase 2 at the selected dose would continue on treatment and be included in the Phase 3 study analysis, supplemented by enrollment of 
approximately 120 additional patients into the Phase 3 portion of the clinical trial, with 2:1 randomization on the same basis as the Phase 2 portion. Efficacy data from 
the Phase 3 could support potential approval using median OS as a primary endpoint. 

On May 12, 2023, we expanded our relationship with Pfizer to support the Phase 2/3 registrational trial to evaluate darovasertib and crizotinib as a combination therapy 
in MUM by entering into Amendment No. 1 to the Second Pfizer Agreement. Under the as-amended Second Pfizer Agreement, Pfizer will provide us with a first 
defined quantity of crizotinib at no cost, as well as an additional second defined quantity of crizotinib at a lump-sum cost. We anticipate that the supply of crizotinib 
under the Second Pfizer Agreement, as amended, will be sufficient to support the planned Phase 2 and Phase 3 portions of the Phase 2/3 potentially registrational 
clinical trial. 

In parallel, we are continuing to evaluate darovasertib in our ongoing Phase 2 clinical trial, designated as IDE196-001, as a combination therapy with crizotinib in 
MUM patients. We are the sponsor of this Phase 2 clinical trial, and are collaborating with Pfizer on this Phase 2 clinical trial pursuant to the Pfizer Agreement.

In April 2023, we reported clinical data, including a safety and clinical efficacy interim results, from the Phase 2 expansion cohort evaluating darovasertib and 
crizotinib combination in MUM. In October 2023, we updated this clinical data and also reported darovasertib clinical ctDNA data and HLA-A2(-)/(+) data subsets 
from this Phase 2 clinical trial, as well as HLA-A2(-)/(+) prevalence based on our broader clinical experience in MUM, at ESMO 2023.

The Phase 2 clinical data, as reported in October 2023, were based on twenty (20) evaluable first-line and sixty-three (63) evaluable any-line patients enrolled as of 
September 22, 2022 in the darovasertib and crizotinib combination study at the expansion dose of 300 mg twice-a-day darovasertib and 200 mg twice-a-day crizotinib. 
Reported data were preliminary and based on investigator review from an unlocked database as of the data analyses cutoff date of August 22, 2023.

The evaluable patients generally had a significant disease burden and the evaluable any-line patients were heavily pre-treated. Key parameters for characterizing disease 
burden include baseline lactate dehydrogenase, or LDH, size of the largest metastatic lesion and degree of multi-site metastases. These evaluable patients had baseline 
LDH which was greater than the upper limit of normal in 60% of any-line and 50% of first-line patients. The largest metastatic lesion was greater than 3.0 cm in 65% of 
any-line and 60% of first-line patients, and greater than 8.0 cm in 10% of any-line and 15% of first-line patients. The patient metastases included both hepatic and 
extrahepatic loci in 64% of any-line and 50% of first-line patients. Among any-line patients, 68% had received one or more prior lines of therapy and 43% had received 
two or more prior lines of therapy.

In the twenty (20) evaluable first-line MUM patients in the expansion cohort, the investigator-reviewed data by RECIST 1.1 included: (i) 45% Overall Response Rate, 
or ORR, in First-Line MUM: 9 of 20 evaluable patients had a confirmed PR; (ii) 90% Disease Control Rate, or DCR, in First-Line MUM: 18 of 20 evaluable patients 
showed disease control, including 9 confirmed PRs and 9 stable disease; and (iii) ~7 months median PFS in First-Line MUM.

In the sixty-three (63) evaluable any-line MUM patients at the expansion dose, the investigator-reviewed data by RECIST 1.1 included: (i) 30% ORR in Any-Line 
MUM: 19 of 63 evaluable patients had a confirmed PR; (ii) 89% DCR in Any-Line MUM: 56 of 63 evaluable patients showed disease control, including 19 confirmed 
PRs and 37 stable disease; and (iii) ~7 months median PFS in Any-Line MUM. Notably, the observed median PFS was enhanced from the median PFS of ~5 months as 
previously reported in September 2022 based on thirty-five (35) evaluable Any-Line MUM patients.

There was a subset of nineteen (19) evaluable hepatic-only MUM patients – including first-line and pre-treated patients with only hepatic metastases, for whom the 
investigator-reviewed data by RECIST 1.1 included: (i) 37% ORR in Hepatic-Only MUM: 7 of 19 evaluable patients had a confirmed partial response (PR); (ii) 100% 
DCR in Hepatic-Only MUM: 19 of 19 evaluable patients showed disease control, including 7 confirmed PRs and 12 stable disease; and (iii) ~11 months median PFS in 
Hepatic-Only MUM.

Treatment durations as of the August 22, 2023 data analyses cutoff date were observed for the Any-Line (n=63) patients: approximately 50% of patients were treated 
for greater than six months, and approximately 30% of patients were treated for greater than one year. Multiple patients with confirmed PRs by RECIST 1.1 have been 
on treatment greater than 24 months, with the potential for further enhancement on the duration of treatment analysis as approximately 20% (13 out of 63 evaluable 
patients) of any-line MUM patients are continuing on treatment.

Based on the two-year PFS Kaplan-Meier curve of the darovasertib and crizotinib combination in any-line MUM, the combination provides a promising PFS trend 
compared to other therapies, including tebentafusp. The observed tail of the PFS curve implies durable benefit in a significant proportion of patients who remain 
progression free as far out as two years.

Circulating tumor DNA (ctDNA) molecular responses reported at ESMO 2023 were determined based on measured changes in mean allele frequency (MAF) on-
treatment as compared to MAF levels at baseline for a subset of any-line MUM patients (n=32). Patients whose ctDNA showed a reduction of greater than 50% MAF 
following treatment were characterized as having a ctDNA molecular response, or MR. 

A reduction in MAF was observed in all but one patient. Significantly, ctDNA MRs were observed in 30 of 32 evaluable patients, reflecting a molecular response rate 
of 94%. The determined ctDNA molecular responses were deep and sustained, with approximately 80% of measured patients having >80% reduction in MAF. The 
ctDNA molecular responses correlated with observed efficacy, including confirmed PRs as determined by RECIST 1.1.

9

 
 
 
 
 
 
 
 
 
 
Clinical efficacy was observed in both HLA-A2(-) and HLA-A2(+) patients. There were 50 all-line MUM patients with known HLA-A2 status among the 63 patients 
evaluable for efficacy, with 31 of these being HLA-A2(-) and 19 being HLA-A2(+). The reported efficacy data by HLA-A2 serotype was based on a preliminary 
analysis of an unlocked database as of August 22, 2023 by investigator review and RECIST 1.1. For HLA-A2(-) MUM patients, confirmed partial responses (PRs) were 
observed in 9 of 31 (29% ORR) any-line and in 5 of 12 (42% ORR) first-line patients. For HLA-A2(+) MUM patents, confirmed PRs were also observed in 6 of 19 
(32% ORR) any-line and in 3 of 5 (60% ORR) first-line patients.

As reported in April 2023, the darovasertib and crizotinib combination therapy continued to observe a manageable safety profile in MUM patients (n=68) at the 
combination expansion doses, with a low rate (10%) of drug-related serious adverse events, or SAEs. Patients reported predominantly Grade 1 or 2 drug-related adverse 
events, or AE’s: 31% of patients reported at least one drug-related Grade 3 AE; no patients observed a drug-related Grade 4 AE; and one patient observed a Grade 5 
AE. The reported Grade 5 SAE was, we believe, not likely related to study therapies and most likely due to disease progression. Drug-related adverse events observed 
in the darovasertib and crizotinib combination in MUM patients as related to darovasertib as of August 22, 2023 primarily include: SAEs of diarrhea, vomiting, sepsis, 
respiratory failure, syncope, hypotension and toxic epidermal necrolysis; and AEs, that occurred in greater than 20% of patients, of diarrhea, nausea, edema peripheral, 
vomiting, dermatitis acneiform, fatigue, hypotension, hypoalbuminaemia, dizziness and decreased appetite. The treating investigator assessed the Grade 5 SAE as being 
of unknown cause, most likely related to disease progression, and possibly related to the study therapies. Principal investigators on the study reviewed the Grade 5 SAE 
and concluded that the event was most likely due to disease progression. As the sponsor of the clinical trial, we likewise concluded the Grade 5 SAE was most likely 
due to disease progression and not likely related to study therapies. Five (7%) of patients permanently discontinued treatment with darovasertib and crizotinib due to a 
drug-related adverse event.

We consider that these data demonstrate robust clinical efficacy of the darovasertib and crizotinib combination in first-line and any-line MUM patients, with a 
manageable safety profile, and that collectively, these data support the potential registration-enabling Phase 2/3 clinical trial to evaluate darovasertib and crizotinib as a 
combination therapy in MUM.

We are continuing to evaluate patients in our Phase 2 clinical trial for darovasertib in combination with crizotinib in MUM. In May 2023, we continued our relationship 
with Pfizer by entering into Amendment No. 4 to the Pfizer Agreement relating to the supply of crizotinib in support of this Phase 2 clinical trial, pursuant to which 
Pfizer will continue to provide IDEAYA with an additional defined quantity of crizotinib at no cost.

We also expanded our relationship with Pfizer in May 2023 under an Amendment No. 1 to the Second Pfizer Agreement to support the Phase 2/3 registrational trial to 
evaluate darovasertib and crizotinib as a combination therapy in MUM. Under the as-amended Second Pfizer Agreement, Pfizer will provide us with a first defined 
quantity of crizotinib at no cost, as well as an additional second defined quantity of crizotinib at a lump-sum cost.

Prevalence of HLA-A2*02:01 Negative Serotype in MUM

Data from darovasertib clinical trials in MUM demonstrate that approximately 70% of MUM patients with known HLA-A*02:01, or HLA-A2 status were HLA-A2(-). 
As reported at ESMO 2023, the HLA-A2 status was known in subsets of patients enrolled in clinical trials evaluating darovasertib. Prevalence of HLA-A2(+) and HLA-
A2(-) in MUM patients was determined from a first data set of n=149 MUM patients treated with darovasertib as monotherapy or in a combination arm of a clinical 
trial, and separately in a second data set of n=118 MUM patients treated with the darovasertib and crizotinib combination. These data include 102 of 149 (68%) of 
patients in the all-treatment subset and 81 of 118 (69%) patients in the darovasertib and crizotinib combination treatment subset.

Darovasertib – Strategy for HLA-A*02:01 Positive MUM

Based on clinical data from the Phase 2 clinical trial evaluating darovasertib and crizotinib in MUM as reported at ESMO 2023, and based on the darovasertib 
mechanism of action, we anticipate darovasertib may have clinical activity independent of HLA-A2 status in GNAQ/11-mutation cancers.

10

 
 
 
 
 
 
 
 
 
 
We are planning to enroll additional HLA-A*02:01 positive, or HLA-A2(+), patients as an independent clinical strategy to address HLA-A2(+) MUM patients, in a 
clinical study. This strategy reflects observed darovasertib clinical activity irrespective of HLA serotype as reported at ESMO 2023, and demonstrates our commitment 
to fully address the high unmet medical need in MUM. Such clinical trial data from darovasertib and crizotinib combination treatment in HLA-A2(+) MUM could 
support publication and potential inclusion in NCCN Clinical Practice Guidelines in Oncology.

Darovasertib – Orphan Drug Designation in UM and Fast Track Designation in MUM

In April 2022, the FDA designated darovasertib as an Orphan Drug in UM, including primary and metastatic disease under 21 C.F.R Part 316. Under an Orphan Drug 
designation, darovasertib may be entitled to certain tax credits for qualifying clinical trial expenses, exemption from certain user fees and, subject to FDA approval of a 
New Drug Application, or NDA, for darovasertib in UM, eligibility for seven years of statutory marketing exclusivity. As an FDA-designated Orphan Drug, 
darovasertib may also be excluded from certain mandatory price negotiation provisions of the 2022 Inflation Reduction Act, if approved.

In November 2022, the FDA granted Fast Track designation to IDEAYA’s development program investigating darovasertib in combination with crizotinib in adult 
patients being treated for MUM. The Fast Track designation makes our darovasertib and crizotinib development program eligible for various expedited regulatory 
review processes, including generally more frequent FDA interactions, such as meetings and written communications, potential eligibility for rolling review of a future 
NDA and potential accelerated approval and priority review of an NDA.

Darovasertib - Neoadjuvant and Adjuvant Therapy in Uveal Melanoma (UM)

We are clinically evaluating the potential for darovasertib as neoadjuvant or adjuvant therapy, or both, also referred to as (neo)adjuvant therapy, in primary, non-
metastatic UM patients. In April 2023, June 2023 and October 2023, we reported preliminary clinical data in the neoadjuvant setting showing evidence of anti-tumor 
activity that we believe supports further clinical evaluation of darovasertib to determine its potential as a neoadjuvant therapy to either save the eye by avoiding 
enucleation, or to reduce the tumor thickness in the eye, enabling treatment with less radiation to preserve vision, and as an adjuvant therapy, to potentially extend 
relapse free survival. 

We have initiated and dosed our first patient in a company-sponsored Phase 2 clinical trial designated as IDE196-009, with ongoing enrollment and multiple clinical 
sites open. The purpose of the clinical trial is to evaluate single-agent darovasertib as neoadjuvant treatment of primary UM prior to primary interventional treatment of 
enucleation or radiation therapy and also as adjuvant therapy following the primary treatment. As of October 23, 2023, six patients have enrolled in the trial, including 
four enucleation patients and two plaque-therapy patients.

The IDE196-009 clinical protocol includes neoadjuvant treatment with darovasertib to maximum benefit up to 6 months, primary treatment, then up to 6 months of 
follow-up adjuvant therapy.

In the neoadjuvant setting, one cohort of UM patients with large tumors will be treated with darovasertib until maximum benefit or six months, at which time they will 
undergo a primary interventional treatment. The neoadjuvant endpoint for this large-sized tumor cohort is eye preservation. For example, a patient who would otherwise 
have undergone enucleation would instead be eligible for radiation treatment. Another neoadjuvant cohort of UM patients with small or medium tumors will be treated 
with darovasertib until maximum benefit or six months, at which time they will undergo radiation therapy. Neoadjuvant endpoints for this small- or medium-sized 
tumor cohort include (i) reducing the radiation dose that the patient receives, relative to the radiation dose they would have otherwise received without the neoadjuvant 
treatment, and (ii) functional vision preservation.

In the adjuvant setting, each of the two neoadjuvant cohorts will be treated with darovasertib for up to six months as follow-up adjuvant therapy after the primary 
interventional treatment. The adjuvant endpoints for this portion of the clinical trial include relapse free survival and useful vision.

11

 
 
 
 
 
 
 
 
 
 
 
We are additionally supporting evaluation of darovasertib as (neo)adjuvant therapy in primary UM in the ongoing NADOM IST. Pursuant to an as-amended protocol for 
the NADOM study, uveal melanoma patients who would otherwise undergo enucleation are instead treated with single agent darovasertib as neoadjuvant treatment for 
up to six months or maximum benefit. This reflects an increase in potential treatment duration versus the initial approach of one month neoadjuvant therapy, following 
which these patients will undergo a primary interventional treatment. Patients will subsequently be treated with darovasertib for up to six months as follow-up adjuvant 
therapy after the primary interventional treatment. 

In October 2023, we reported clinical data demonstrating clinical activity for darovasertib as neoadjuvant therapy in primary UM, including tumor shrinkage in ocular 
tumor lesions. The preliminary interim update was based on investigator review with an enrollment and data cut-off as of July 17, 2023, in the enucleation cohort of the 
NADOM IST. In total, 11 patients eligible to receive six months of neoadjuvant therapy have been enrolled as of October 23, 2023 in the neoadjuvant UM enucleation 
cohort of the NADOM IST.

The company reported that seven patients were treated to maximal response or have ongoing treatment with darovasertib in the neo-adjuvant setting as of the data cut-
off date of July 17, 2023. Six of these seven patients were considered evaluable based on evaluation with at least one ultrasound scan. Two evaluable patients had a 
confirmed eye preservation and avoided enucleation, based on conversion of their primary treatment from the planned enucleation to plaque brachytherapy. A third 
evaluable patient was confirmed as plaque-eligible and treatment of this patient is ongoing with darovasertib neo-adjuvant treatment until maximal benefit. These data 
reflect eye preservation in three of six evaluable patients – a 50% eye preservation rate. Of the evaluable six patients, approximately 83% of patients had tumor 
shrinkage. 

Two patients enrolled into the IST did not complete their treatment to maximal response. One of these patients had sub-retinal blood present at baseline and with lack of 
shrinkage and visual deterioration and the patient discontinued treatment after 6 weeks. A second of these patients had a Grade 3 drug-related AE of dermatitis and 
discontinued treatment before a first scan.

Enrollment into the IST is ongoing. As of October 23, 2023, two out of four additional patients enrolled after the data cutoff date of July 17, 2023, are likely plaque 
eligible – based on an observed 22% ocular tumor shrinkage at 1-month and 20% ocular tumor shrinkage at 2-months, and are continuing darovasertib neoadjuvant 
therapy until maximal benefit. One patient is being enucleated. The status of the fourth patient was not reported.

In April 2023, we reported on a compassionate use case for a primary UM patient who was already blind in one eye from vascular disease and developed a large uveal 
melanoma lesion in his other eye which also had an associated cataract. The patient sought neoadjuvant treatment with the darovasertib and crizotinib combination 
under a compassionate use protocol with a goal to avoid enucleation and potentially preserve vision in the affected eye. The preliminary clinical data showed prompt 
responsiveness to treatment, including observed progressive tumor shrinkage over each prior month of treatment. Namely, the patient experienced ~30% tumor 
shrinkage after one month that continued up to ~80% after 4 months of treatment, in each case as determined by investigator measurement of apical height. After 1 
month the ocular lesion size was sufficiently reduced to approach the threshold for radiation therapy (e.g., plaque brachytherapy). The patient thus avoided enucleation 
of the eye having the uveal melanoma, which reflects an initial reported case of systemic neoadjuvant therapy resulting in eye preservation by avoiding enucleation. 
Additionally, the patient has restored normal vision of the eye following the course of neoadjuvant treatment and treatment of the associated cataract, with a reported 
post-treatment vision score of 6/5 (measurement in meters: 6/6 m = 20/20 ft), reflecting a greater than 20 fold improvement in vision.

In June 2023, we reported a second case of a primary UM patient who was spared enucleation, which was also the first reported case of a primary UM patient who was 
treated with darovasertib as monotherapy neoadjuvant therapy and was spared enucleation in the Phase 1 (neo)adjuvant IST. In this reported case, the UM patient 
observed a 24% reduction in tumor size following four months of neoadjuvant treatment with darovasertib as monotherapy. The reduction in tumor size enabled plaque 
brachytherapy as a primary interventional treatment rather than an originally planned enucleation.

We believe that these clinical observations provide a basis for further clinical investigation to evaluate whether darovasertib can improve current primary treatment 
paradigms, which typically include radiotherapies or enucleation of the eye as primary interventional treatments. Our regulatory strategy includes evaluation of 
potential 

12

 
 
 
 
 
 
 
 
clinical endpoints such as vision and organ preservation which would be temporally proximal to the primary interventional treatments, potentially enabling a discussion 
with regulatory authorities on an accelerated approval pathway.

Darovasertib – Expansion Opportunity in Skin Melanoma

We have initiated a Phase 2 expansion arm in our IDE196-001 clinical trial evaluating the darovasertib and crizotinib combination in GNAQ/11 metastatic cutaneous 
melanoma, also referred to as skin melanoma, based on the observed preliminary clinical efficacy. In the darovasertib monotherapy cutaneous melanoma cohort (n=8), 
five of seven evaluable patients had tumor shrinkage (approximately 71%) with one patient having a PR and remaining on treatment over 10 months after previously 
receiving multiple lines of immunotherapy. In the darovasertib plus binimetinib cutaneous melanoma cohort (n=2), one of two cutaneous melanoma patients with a PR 
demonstrated 50% tumor shrinkage and remained on treatment approximately 600 days after previously receiving multiple lines of immunotherapy. In the darovasertib 
plus crizotinib cutaneous melanoma cohort (n=2), one of two cutaneous melanoma patients had tumor shrinkage of 60% with one patient having a PR and remaining on 
treatment approximately 600 days after previously receiving multiple lines of immunotherapy.

Darovasertib, as monotherapy or in combination with either binimetinib or crizotinib, has indicated a manageable safety profile in cutaneous melanoma patients with 
certain drug-related AEs being reported in all cohorts. These preliminary clinical data support initiation of a Phase 2 expansion of the darovasertib and crizotinib 
combination in GNAQ/11 metastatic cutaneous melanoma to advance the darovasertib and crizotinib combination. There are currently no FDA approved therapies in 
this indication in this genetically-defined patient population.

The GNAQ/11 prevalence in cutaneous melanoma has been reported at approximately 5% in The Cancer Genome Atlas. The GNAQ/11 cutaneous melanoma estimated 
annual incidence is approximately 5,000 patients in the United States and 8,000 patients in the EU28, and the estimated total prevalence of GNAQ/11 cutaneous 
melanoma is approximately 70,000 patients in the United States and 110,000 patients in the EU28. It has been reported that approximately 12.5% to 15% of cutaneous 
melanoma patients have been reported to develop metastatic disease.

IDE397 – MAT2A Inhibitor in Tumors with MTAP Deletion

IDE397 is a clinical-stage, potent, selective small molecule inhibitor of MAT2A, which we are developing for patients having solid tumors with MTAP deletion. The 
prevalence of MTAP deletion is estimated to be approximately 15% of human solid tumors. MTAP deletion in patient tumors is identified by commercial or 
institutional next generation sequencing, or NGS, panels or by MTAP immunohistochemistry, or IHC, assay with confirmation by NGS.

MTAP-null cells lack the ability to metabolize 5-methylthioadenosine, or MTA, which is an essential step in a biochemical pathway involved in salvaging the 
metabolite S-adenosyl methionine, or SAM. Increased levels of MTA partially inhibit the methyltransferase PRMT5 for which SAM is the methyl-donor substrate for 
methylation of various proteins. This partial inhibition of PRMT5 by increased levels of MTA renders MTAP-null cells more dependent on the activity of MAT2A, an 
enzyme that is responsible for the synthesis of SAM. Because of this enhanced dependence, loss of MTAP results in synthetic lethality when MAT2A is 
pharmacologically inhibited.

We are enrolling patients into a Phase 2 clinical trial designated as IDE397-001 to evaluate IDE397 for patients having certain tumors with MTAP gene deletion. We are 
proceeding with enrollment of MTAP-deletion patients into a monotherapy Phase 2 expansion cohort with an initial focus on high priority solid tumor types, including 
squamous NSCLC, bladder, esophageal and gastric cancers. In June 2023, we announced selection of a Phase 2 monotherapy expansion dose for IDE397 and in 
connection therewith, reported preliminary evidence of clinical activity as monotherapy. We observed tumor shrinkage in multiple patients treated with IDE397 
monotherapy in our high-priority MTAP-deletion solid tumor types based on experience across several patients in the early phase of the monotherapy dose expansion. 
Specifically, there have been eight patients dosed in the Phase 2 expansion in the high priority solid tumor types of squamous NSCLC and bladder cancer, of which two 
patients have not yet had a first tumor scan assessment. The PRs include an earlier reported 33% tumor shrinkage by CT-PET (without contrast) for a squamous NSCLC 
patient, and a confirmed PR (47% tumor shrinkage) by RECIST 1.1 with IDE397 in a previously undisclosed tumor type (bladder cancer). This bladder cancer patient 
has converted to a complete response by RECIST 1.1 at the week 18 CT-scan. In addition, of patients evaluable for ctDNA pre and post treatment, a ctDNA molecular 

13

 
 
 
 
 
 
 
 
 
response rate of 83% was observed in these MTAP-deletion priority tumor types. As of the October 13, 2023 cut-off date, we have observed low rates of drug-related 
discontinuations and SAEs in the dose escalation and expansion phases. Patients reported predominantly Grade 1 or 2 drug-related AEs: nine patients reported at least 
one Grade 3 drug-related AE; no patients observed a Grade 4 drug-related AE or Grade 5 drug-related AE.

We are collaborating with Amgen to clinically evaluate IDE397 in combination with AMG 193, the Amgen investigational MTA-cooperative PRMT5 inhibitor, in 
patients having tumors with MTAP deletion, in an Amgen-sponsored clinical trial pursuant to the Amgen CTCSA.

The combination of IDE397 with AMG 193 is a novel and potential first-in-class synthetic lethality combination which targets two distinct and mechanistically 
complementary nodes of the MTAP methylation pathway – MAT2A and PRMT5, providing a complementary approach for targeting MTAP-null tumors.

In August 2023, Amgen initiated and has dosed a first patient in the IDE397 /AMG 193 combination study, following FDA authorization to proceed with the clinical 
trial. This Phase 1/2 clinical trial (NCT: 05975073) will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of IDE397 in combination 
with AMG 193, with an initial focus for expansion in NSCLC patients and an estimated enrollment of approximately 180 patients.

In April 2023, we co-presented preclinical efficacy data with Amgen at the 2023 Annual Meeting of the American Association for Cancer Research, or AACR 2023, for 
the IDE397 and AMG 193 combination in a NSCLC MTAP-null cell-derived xenograft, or CDX, model. As reflected in these published xenograft data, we observed 
complete responses following approximately 30 days of combination treatment, starting at study-day 7 through study-day 39, at doses below the maximally efficacious 
preclinical dose for each of IDE397, such as 1/10th of maximally efficacious dose, and AMG 193. The complete responses were durable from approximately study-day 
40 to study-day 100. The IDE397 and AMG 193 combination was well tolerated, with no observed body weight loss through the approximate 30 days of combination 
treatment.

We also presented preclinical efficacy data showing deep and durable anti-tumor efficacy and pharmacodynamic, or PD, responses for IDE397 in combination with 
representative MTA-cooperative PRMT5 inhibitors in NSCLC MTAP-null cell-derived xenograft, or CDX, models, and for one representative compound, also in a 
pancreatic MTAP-null CDX model. 

In addition, we presented further supporting preclinical data at AACR 2023, including the results of gene expression analysis of hallmark pathways, alternative splicing 
analysis and retained intron analysis. These data collectively demonstrate that combined pharmacological inhibition of MAT2A and PRMT5 deepens the biological 
response through maximal pathway suppression. The enhanced combination effect was observed selectively in MTAP-null relative to MTAP wild-type models.

We believe that the preclinical efficacy data, considered together with the biological mechanistic response data, as presented at AACR 2023 supports our plans to 
clinically evaluate IDE397 in combination with AMG 193. We own all right, title and interest in and to IDE397 and the MAT2A program, including all worldwide 
commercial rights thereto.

We are collaborating with Gilead to clinically evaluate IDE397 in combination with Trodelvy, the Gilead Trop-2 directed ADC, in patients having tumors with MTAP 
deletion, in patients having MTAP deletion bladder cancer, in an IDEAYA-sponsored clinical trial pursuant to the Gilead CSCSA.

IDE161 – PARG Inhibitor in Tumors with Homologous Recombination Deficiency 

We are evaluating IDE161, a small molecule inhibitor of PARG being evaluated in a Phase 1/2 clinical trial designated as IDE161-001 for patients having tumors with 
HRD and potentially other genetic and/or molecular signatures. PARG is a novel target in a clinically validated biological pathway. PARG functions as a regulator of 
DNA repair in the same biochemical pathway as PARP. PARG hydrolyzes poly (ADP-ribose), or PAR, chains that are polymerized by PARP enzymes, completing the 
PAR cycle. Small molecule inhibitors of PARG result in a dose dependent increase in cellular PAR after DNA damage. PARG is a mechanistically distinct target 
relative to PARP.

14

 
 
 
 
 
 
 
 
 
 
 
We are progressing with enrollment of patients having tumors with HRD into the Phase 1 expansion portion of the Phase 1/2 clinical trial in selected priority tumors. In 
parallel, we are also continuing with Phase 1 dose optimization to confirm a move-forward expansion dose for the planned Phase 2 portion of the clinical trial. We are 
targeting clinical program update(s) in 2024. We are also validating IDE161 combination opportunities preclinically and targeting identification of potential 
combination(s) in 2024.

The expansion portion of the Phase 1 trial will include patients having HRD-associated breast cancer and ovarian cancer, as well as a basket of other selected solid 
tumors. The breast cancer focus is on ER+, Her2-, HRD+ tumors, which represent approximately 10% to 14% of breast cancer patients. The ovarian cancer focus 
represents approximately 50% of ovarian cancer where HRD is observed. Selected other solid tumors with HRD, such as HRD+ endometrial cancer, will also be 
evaluated in the Phase 1 expansion portion of the clinical trial.

In connection with the Phase 1 expansion announced in September 2023, we disclosed preliminary clinical proof-of-concept for IDE161 in HRD solid tumors based on 
early clinical data from the dose escalation cohorts. These clinical data showed dose-dependent pharmacodynamic modulation of PAR proteins in peripheral blood, 
demonstrating IDE161 target engagement. These clinical data also demonstrated IDE161 exposure levels in humans which correlate to preclinical exposures that were 
efficacious in achieving tumor regressions in xenograft models. We observed preliminary tumor shrinkage observed in multiple HRD solid tumor patients, including an 
BRCA1/2 endometrial cancer subject with a first imaging assessment of a partial response in the target lesion, a complete response in the non-target lesion and an 87% 
reduction in the CA-125 tumor marker (2,638 units/ml at baseline to 360 units/ml at 6-weeks).

We have observed multiple PRs by RECIST 1.1 and tumor shrinkage in priority solid tumor types early in the Phase 1 dose escalation and at the expansion dose. As of 
October 13, 2023, there have been a total of seven patients treated at the expansion dose, of which two patients have not yet had a first scan tumor assessment. We 
observed preliminary tumor shrinkage in multiple HRD solid tumor patients, including an BRCA1/2 endometrial cancer subject with a confirmed PR in the target lesion 
as of the second imaging assessment, a complete response in the non-target lesion and an 87% reduction in the CA-125 tumor marker (2,722 units/ml at baseline to 360 
units/ml at six-weeks). At the IDE161 expansion dose, we have observed no drug-related discontinuations or SAEs as of the October 13, 2023 cut-off date.

In September 2023, we received Fast Track Designation from the FDA for IDE161 for ovarian cancer and breast cancer indications. Fast Track is a FDA process 
designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. Specifically, for IDE161, Fast Track 
Designation was received for the treatment of adult patients having advanced or metastatic ovarian cancer with germline or somatic BRCA 1/2 mutations who are 
platinum resistant and have received prior antiangiogenic and PARP inhibitor therapies. The Fast Track Designation was also received for IDE161 for the treatment of 
adult patients having advanced or metastatic HR+, Her2- breast cancer with germline or somatic BRCA 1/2 mutations who have progressed following treatment with at 
least one line of a hormonal therapy, a CDK4/6 inhibitor therapy and a PARP inhibitor therapy.

Under the Fast Track designation, the IDE161 development program in BRCA1/2 mutant (m) breast and ovarian cancers, as specified in the respective Fast Track 
designation, is eligible for various expedited regulatory review processes, including generally more frequent FDA interactions (e.g., meetings, written communications), 
potential eligibility for rolling review of an and potential accelerated approval and priority review of a future NDA.

We entered into an exclusive license under the Evaluation, Option and License Agreement, by and among the Company, Cancer Research Technologies Ltd., also 
known as Cancer Research United Kingdom, or CRT, and the University of Manchester, pursuant to which we hold exclusive worldwide license rights covering a broad 
class of PARG inhibitors.

In April 2023, we incurred an obligation to pay milestone payments in an aggregate amount of £750,000 to CRT based upon the achievement of certain milestones 
relating to first and second tumor histologies in connection with the Phase 1 portion of the IDE161-001 Phase 1/2 clinical trial in oncologic diseases. The Company will 
be obligated to make additional payments to CRT aggregating up to £18.75 million upon the achievement of specific development and regulatory approval events for 

15

 
 
 
 
 
 
 
 
 
development of a PARG inhibitor in oncologic diseases, including an aggregate of up to £1.5 million and up to £2.25 for the achievement of certain Phase 2 and Phase 3 
development milestones, respectively, in each case as relating to first and second tumor histologies.

We own or control all commercial rights in our PARG program, subject to certain economic obligations pursuant to our exclusive, worldwide license to certain PARG 
inhibitors, including IDE161, with CRT and University of Manchester.

GSK101 (IDE705) - Pol Theta Helicase Inhibitor in tumors with Homologous Recombination Deficiency

We discovered GSK101 (IDE705), our Pol Theta Helicase inhibitor clinical development candidate, and evaluated GSK101 in preclinical studies in collaboration with 
GSK. GSK101 targets the helicase domain of the Pol Theta protein for patients having solid tumors with BRCA or other mutations associated with HRD.

Pol Theta is involved in a DNA repair process called microhomology mediated end joining, or MMEJ, that is utilized when homologous recombination mediated repair 
is compromised, as happens in the case of certain BRCA1 or BRCA2 mutations. The expression of Pol Theta is largely absent in normal cells, but tumor cells harboring 
double strand break repair defects, such as BRCA1 or BRCA2 mutations, show higher Pol Theta expression and synthetic lethality when Pol Theta is inhibited. Pol 
Theta is a large protein with two functional domains: a DNA polymerase domain and an ATP-dependent DNA helicase domain, sometimes referred to as an ATPase 
domain, linked by a RAD51 central region.

GSK is evaluating GSK101 in combination with niraparib, the GSK small molecule inhibitor of PARP for the treatment of patients having tumors with BRCA or other 
HR mutations, or HRD, in a GSK-sponsored Phase 1 clinical trial. GSK has dosed the first patient in this trial.

GSK is leading clinical development of GSK101 pursuant to the GSK Collaboration Agreement. GSK is responsible for all research and development costs for the Pol 
Theta program.

We have the potential to receive an additional $10.0 million milestone payment upon initiation of Phase 1 clinical dose expansion. In August 2023, we achieved and 
earned a $7.0 million milestone based on acceptance of the IND by the FDA, for which payment was received in October 2023. An earlier preclinical development $3.0 
million milestone payment from GSK was achieved in August 2022 in connection with ongoing IND-enabling studies to support evaluation of GSK101.

We have the potential to earn further aggregate late-stage development and regulatory milestones of up to $465 million. Upon commercialization, we will be eligible to 
receive up to $475 million of commercial milestones, and tiered royalties on global net sales of GSK101 – ranging from high single-digit to sub-teen double-digit 
percentages, subject to certain customary reductions. 

WRN Inhibitors in Tumors with High Microsatellite Instability 

We are advancing our preclinical IND-enabling studies and other preclinical research in collaboration with GSK for an inhibitor targeting Werner Helicase for patients 
having tumors with high MSI.

WRN protein is a RecQ enzyme involved in the maintenance of genome integrity. Germline loss of function mutations in WRN lead to premature aging and pre-
disposition to cancer. MSI is a change in the DNA content of a tumor cell in which the number of repeats of microsatellites, short repeated sequences of DNA, differ as 
cells divide. High MSI is present in about 15% of gastrointestinal tumor cancers, including in approximately 22% of stomach adenocarcinoma and 16% of colorectal 
cancer. Tumors with high MSI are routinely assessed in multiple diagnostic profiling tests.

16

 
 
 
 
 
 
 
 
 
 
 
 
 
WRN is a protein having several functional domains, and we have shown that the helicase functional domain of WRN is responsible for this synthetic lethal interaction, 
as reflected in our publication in Cell Press - iScience, Werner Syndrome Helicase is Required for the Survival of Cancer Cells with Microsatellite Instability (March 
2019).

We have demonstrated in vivo efficacy with tumor regression and PD response in a relevant high MSI model. We have observed selectivity of our Werner Helicase 
inhibitor and validation of the synthetic lethal relationship to tumors with high MSI over tumors with microsatellite stable, or MSS, based on a lack of in vivo 
pharmacological response in relevant MSS xenograft models.

We selected a Werner Helicase Inhibitor DC in collaboration with GSK. Subject to successful completion of ongoing IND-enabling studies, we are targeting an IND 
submission in 2024 to enable first-in-human clinical evaluation of Werner Helicase Inhibitor DC for patients having tumors with high MSI.

We are collaborating with GSK on the ongoing IND-enabling studies and, subject to IND submission and clearance, GSK will lead clinical development for the Werner 
Helicase program. GSK is responsible for 80% of global research and development costs and IDEAYA is responsible for 20% of such costs. GSK holds a global, 
exclusive license to develop and commercialize the Werner Helicase Inhibitor DC.

In October 2023, we achieved and earned a $3 million milestone in connection with IND-enabling studies. We have the potential to earn up to an additional $17 million 
aggregate milestone payments through early Phase 1 clinical studies, including $7.0 million upon IND clearance. We are also eligible to receive additional future 
aggregate total development milestones of up to $465 million. Upon commercialization, we will be eligible to receive up to $475 million of commercial milestones, 
50% of U.S. net profits and tiered royalties on global non-U.S. net sales of the Werner Helicase Inhibitor DC – ranging from high single-digit to sub-teen double-digit 
percentages, subject to certain customary reductions.

Next-Generation Precision Medicine Pipeline Programs 

We have initiated early preclinical research programs focused on pharmacological inhibition of several new targets, or NTs, for patients with solid tumors characterized 
by defined biomarkers based on genetic mutations and/or molecular signatures. We believe these research programs have the potential for discovery and development of 
first-in-class or unique-in-class or best-in-class therapeutics. We are targeting development candidate nominations in 2024 for multiple NTs. Collectively, we believe 
these efforts will further advance our multi-pronged clinical and business strategy. We own or control all commercial rights in our next-generation NT programs.

New Target and Biomarker Discovery Platform

Since inception of the company, our core research has and continues to be focused on precision medicine oncology, with synthetic lethality as a central tenet. We have 
invested significantly and continue to invest in capabilities for identification and validation of new precision medicine targets and biomarkers for patient selection. For 
targets of interest, we advance our research to discover therapeutic drugs and to further qualify relevant biomarkers.

DECIPHER™ Dual CRISPER Synthetic Lethality Library – UCSD

We have constructed our DECIPHER Dual CRISPR library for synthetic lethality target and biomarker discovery in collaboration with the University of California, San 
Diego, and bioinformatics analysis and validation are ongoing. The DECIPHER 1.0 library is focused on DNA Damage Repair targets across various
 tumor suppressor genes and oncogenes of interest that were selected based on their known prevalence and role in solid tumors, enabling evaluation of approximately 
50,000 independent gene knockout combinations of DDR pathway related drug targets across known tumor suppressor genes.

PAGEO™ Paralogous Gene Evaluation in Ovarian Cancer and Dep Map Consortium – Broad Institute

17

 
 
 
 
 
 
 
 
 
 
 
 
 
We have an ongoing strategic collaboration with the Broad Institute focused on synthetic lethality target and biomarker discovery. This collaboration will use the large-
scale CRISPR paralog screening platform developed at the laboratory of William R. Sellers, M.D., Core Institute Member, Broad Institute, to evaluate functionally 
redundant paralogous genes across ovarian cancer subtypes and to generate novel target and biomarker hypotheses. Dr. Sellers, who also serves on our Scientific 
Advisory Board, is the principal investigator for the strategic collaboration. We have also become a member of the Broad DepMap (Cancer Dependency Map) 
consortium led by the Broad Institute to further enhance our efforts in bioinformatics and cell-based screening for synthetic lethality target and biomarker discovery and 
validation. 

Drug Discovery and Program Biomarker Discovery Platform 

We are also continuing to invest in our capabilities to advance our research on newly identified synthetic lethality targets of interest, including to enable discovery of 
therapeutic drugs and program relevant biomarkers. These investments include both additional research personnel and capital investments, which will enhance our 
capabilities broadly, including in target validation, biological assay development, protein synthesis, structural biology, computational chemistry, and analytical 
chemistry, among other core functional areas.

As examples of aspects of our drug discovery platform, we use our INQUIRE™ Chemical Library to enhance our synthetic lethality drug discovery platform. 
INQUIRE is a proprietary, expert-curated small-molecule library of over 200,000 chemical compounds, which we believe will enhance our hit discovery capabilities 
across a broad range of novel synthetic lethality targets and historically difficult-to-drug target classes, such as helicases and endonucleases.

We use our HARMONY ™ machine-learning engine to empower evaluation and decisions related to structure-activity-relationships analyses, empowering our drug-
discovery platform.

Competition 

Our industry is very competitive and subject to change based on ongoing advances in technology. Although we believe that our approach, strategy, scientific 
capabilities, knowledge and experience provide us with competitive advantages, we expect to have substantial competition from major pharmaceutical companies, 
specialty pharmaceutical companies and biotechnology companies worldwide. Many of our competitors have significantly greater financial, technical and human 
resources. Smaller and early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established 
companies. 

As a result, our competitors may discover, develop, license or commercialize products before or more successfully than we do. We face competition with respect to 
product candidates in our pipeline, and will face competition with respect to future product candidates, from segments of the pharmaceutical, biotechnology and other 
related markets that pursue targeted approaches to addressing activating genetic and other molecular alterations in cancer. 

For darovasertib, we are not aware of other companies actively developing clinical-stage therapeutics directed to PKC as a target for solid tumors. MingSight is 
developing a PKC beta inhibitor in chronic lymphocytic leukemia, or CLL, and diabetic macular edema, both in Phase 1 studies. Varian Biopharmaceuticals is 
advancing a preclinical-stage atypical PCK iota inhibitor, including as a dermatologic gel formulation for potential topical treatment of Basal Cell Carcinoma, or BCC. 
Exscientia is developing a PKC theta inhibitor in inflammatory diseases in Phase 1 studies. Varsity Pharma is developing a PKC inhibitor in CLL. We are aware of 
other companies that are conducting research and development of potential therapies for primary UM or for MUM based on other targets and approaches. For example, 
Aura Biosciences is developing AU-011 a virus-like drug conjugate (VDC) as local treatment for early-stage choroidal melanoma. Immunocore is developing and 
commercializing Tebentafusp, also known under its branded name as Kimmtrak for the treatment of adult patients with HLA-A*02:01-positive unresectable or 
metastatic uveal melanoma. Novartis is developing DYP688, an antibody-drug-conjugate, or ADC, with a GNAQ-11 inhibitor payload in a Phase 1/2 clinical trial in 
MUM.

For IDE397, Servier Pharmaceuticals, LLC, or Servier, is evaluating a small molecule MAT2A inhibitor designated as S95035 in a Phase 1 trial and Insilico Medicine 
has a small molecule MAT2A inhibitor in IND-enabling studies.

For IDE161, we are not aware of any other clinical-stage therapies targeting PARG. Several companies are conducting preclinical research to develop PARG inhibitors, 
including Nodus Oncology, SynRx, 858 Therapeutics and Satya Pharma Innovations. 

For GSK101 (IDE705), Artios Pharma is developing two clinical-stage therapies targeting Pol Theta, both in Phase 1/2 studies. Additionally, Repare Therapeutics and 
Breakpoint Therapeutics have Pol Theta inhibitors in IND-enabling studies. 

For our preclinical pipeline of synthetic lethality therapeutics, potential competition includes established companies as well as earlier-stage emerging biotechnology 
companies. Multiple established companies have been involved with research and development in synthetic lethality, such as AstraZeneca (Lynparza), Pfizer 
(Talzenna), GSK (Zejula) and Roche. Additionally, several other early-stage companies, including 858 Therapeutics, Anticancer Bioscience, Artios, Breakpoint 
Therapeutics, FoRx Therapeutics, Repare Therapeutics, Ryvu Therapeutics, Tango, Vividion, Xpose, and Eikon Therapeutics.

Strategic Relationships 

We own or control all commercial rights in our three most advanced programs, each of which are clinical-stage programs – darovasertib, IDE397 and IDE161. We have 
entered into strategic relationships for these programs – for example, to in-license certain intellectual property rights or to enable evaluation of combination therapies, 
such as through combination drug supply or clinical trial collaborations to evaluate combinations. For darovasertib, we have an exclusive license agreement with 
Novartis and separately, we have established clinical trial collaboration and supply agreements with Pfizer in support of our clinical evaluation of darovasertib in 
combination with crizotinib in MUM and cutaneous melanoma. For IDE397, we entered into the Amgen CTCSA to clinically evaluate IDE397 in combination with 
AMG 193, the Amgen investigational MTA-cooperative PRMT5 inhibitor, in patients having MTAP-null solid tumors, and we entered into the Gilead GSCSA to 
clinically evaluate IDE397 in combination with Trodelvy, the Gilead Trop-2 directed ADC, in patients having MTAP deletion bladder cancer. For PARG, we have an 
exclusive in-license agreement with Cancer Research UK and University of Manchester. 

We have entered into a strategic partnership and collaboration with GSK for our preclinical synthetic lethality programs targeting Pol Theta and Werner Helicase, 
pursuant to the GSK Collaboration Agreement. We own all commercial rights in our earlier next-generation synthetic lethality programs, for which our small molecule 
compounds are being discovered and/or developed internally with our own resources, as supplemented by certain service providers such as CROs. 

We have established collaborative relationships with other companies for access to their proprietary database of patient samples, and/or for their genetic screening 
services on their proprietary platform. We have established certain development manufacturing and service relationships with CMOs for darovasertib, IDE397, and 
IDE161 We have an agreement with STA Pharmaceutical Hong Kong Limited, or STA Pharmaceutical, for the synthesis of the API for darovasertib, and agreements 
with STA Pharmaceutical and Patheon Inc. for formulation and manufacturing of darovasertib drug product. We have an agreement with STA Pharmaceutical for the 
synthesis of the API, formulation and manufacturing of IDE197 drug product. We have an agreement with Pharmaron for the synthesis of the API and formulation for 
IDE161, and with STA Pharmaceutical for the manufacturing of IDE161 drug product. We have established arrangements with CMOs as well for packaging, labeling 
and distribution of darovasertib, IDE397, and IDE161. We also have established clinical services relationship with CROs to support our conduct of clinical trials for our 
darovasertib, IDE397, and IDE161programs.

In addition to these existing strategic license relationships, existing and planned development manufacturing and service arrangements, and existing and planned 
clinical services arrangements, we have various existing agreements and relationships with service providers, such as CROs, which are enabling execution of various 
research and development activities for each of our pipeline programs. In particular, such agreements are directed to chemistry and compound synthesis, compound 
analysis and characterization, structural biology, computational biology, biological assay and model development, in vitro screening, in vivo screening, translational 
biomarker diagnostic development, bioinformatics, toxicology and formulation, among other activities.

We may also evaluate future strategic opportunities to accelerate development timelines and maximize the commercial potential of our product candidates. We plan to 
selectively evaluate strategic collaborations with biopharmaceutical partners whose research, development, commercial, marketing, and geographic capabilities 
complement our own.

Agreements 

Clinical Trial Collaboration and Supply Agreements with Pfizer for Darovasertib

In March 2020, we entered into the Pfizer Agreement. Pursuant to the Pfizer Agreement, as amended in September 2020, April 2021, August 2021 and May 2023, 
Pfizer supplies us with their MEK inhibitor, binimetinib, and their cMET inhibitor, crizotinib, to evaluate combinations of darovasertib independently with each of the 
Pfizer compounds, in patients with tumors harboring activating GNAQ or GNA11 mutations. Under the Pfizer Agreement, we are the sponsor of the combination 
studies and will provide darovasertib and pay for the costs of the combination studies. Pfizer will provide binimetinib and crizotinib for use in the clinical trial at no cost 
to us. The Pfizer Agreement provides that we and Pfizer will jointly own clinical data generated from the clinical trial and will also jointly own inventions, if any, 
relating to the combined use of darovasertib and binimetinib, or independently, to the combined use of darovasertib and crizotinib. We and Pfizer have formed a joint 
development committee responsible for coordinating all regulatory and other activities under the agreement. 

Pfizer may terminate the agreement if Pfizer believes binimetinib or crizotinib is being used in an unsafe manner. Either party may terminate the agreement for patient 
safety reasons, if any regulatory action prevents the supply of its drug or if a party ceases development of its drug. Either party may terminate the agreement for the 
other party’s material breach that remains uncured for thirty days. If the agreement is terminated, we must return any unused binimetinib or unused crizotinib, as 
applicable, to Pfizer. If Pfizer terminates the agreement because of our material breach, we will be required to reimburse Pfizer certain manufacturing costs for the 
binimetinib or crizotinib supplied under the agreement. 

We have further expanded the scope of our relationship with Pfizer, entering into additional agreements to facilitate evaluation of darovasertib in combination with 
crizotinib in a potential registrational clinical trial in MUM and separately, in combination with crizotinib in other cMET-driven tumor indications. 

In March 2022, we and Pfizer entered into the Second Pfizer Agreement pursuant to which we may, subject to FDA feedback and guidance, evaluate darovasertib and 
crizotinib as a combination therapy in MUM in a planned Phase 2/3 potential registration-enabling clinical trial. Pursuant to the Second Pfizer Agreement, we are the 
sponsor of the planned combination trial and we will provide darovasertib and pay for the costs of the combination trial; Pfizer will provide crizotinib for the planned 
combination trial at no cost to us for up to an agreed-upon number of MUM patients. We and Pfizer will jointly own clinical data from the planned combination trial 
and all inventions relating to the combined use of darovasertib and crizotinib. We and Pfizer have formed a joint development committee responsible for coordinating 
all regulatory and other activities under the Second Pfizer Agreement. 

Separately, in March 2022, we and Pfizer also entered into the Third Pfizer Agreement pursuant to which we may, subject to preclinical validation and FDA feedback 
and guidance, evaluate darovasertib and crizotinib, as a combination therapy in cMET-driven tumors such as NSCLC and/or HCC in a Phase 1 clinical trial. Pursuant to 
the Third Pfizer Agreement, we are the sponsor of the planned combination trial, and we will provide darovasertib and pay for the costs of the combination trial; Pfizer 
will provide crizotinib for the planned combination trial at no cost to us. We and Pfizer will jointly own clinical data from the planned combination trial and all 
inventions relating to the combined use of darovasertib and crizotinib. We and Pfizer had formed a joint development committee responsible for coordinating all 
regulatory and other activities under the Third Pfizer Agreement. 

In May 2023, we continued our relationship with Pfizer by entering into Amendment No. 4 to the Pfizer Agreement relating to the supply of crizotinib in support of this 
Phase 2 clinical trial, pursuant to which Pfizer will continue to provide us with an additional defined quantity of crizotinib at no cost.

We also expanded our relationship with Pfizer in May 2023 under an Amendment No. 1 to the Second Pfizer Agreement to support the Phase 2/3 registrational trial to 
evaluate darovasertib and crizotinib as a combination therapy in MUM. Under the as-amended Second Pfizer Agreement, Pfizer will provide us with a first defined 

21

 
 
 
 
 
 
 
 
 
 
quantity of crizotinib at no cost, as well as an additional second defined quantity of crizotinib at a lump-sum cost. Under Amendment No. 1 to the Second Pfizer 
Agreement, we also terminated the Third Pfizer Agreement. 

Exclusive License Agreement with Novartis for Darovasertib

In September 2018, we entered into a license agreement with Novartis International Pharmaceuticals Ltd. (Novartis) to develop and commercialize Novartis’ LXS196 
(also known as IDE196), a Phase 1 protein kinase C (PKC) inhibitor, for the treatment of cancers having GNAQ and GNA11 mutations. We have renamed Novartis’ 
LXS196 oncology as IDE196, and which has a non-proprietary name of darovasertib. 

Under the license agreement, Novartis granted to us a worldwide, exclusive, sublicensable license to research, develop, manufacture, and commercialize certain defined 
compounds and products, including IDE196 and certain other PKC inhibitors as well as companion diagnostic products, collectively referred to as the licensed 
products, for any purpose. The license grant is subject to Novartis’ retained rights to complete its ongoing Phase 1 clinical trial of darovasertib, designated in their 
clinical trial as LXS196. Novartis also agreed to transfer to us certain materials and know-how relating to the licensed products or arising from the ongoing Phase 1 
clinical trial of darovasertib. 

We are solely responsible for the manufacturing and commercialization of the licensed products, subject to Novartis’ rights under the ongoing clinical trial of 
darovasertib. We have certain obligations to supply darovasertib and licensed products for compassionate use, named patient and similar programs in connection with 
the ongoing clinical trial. We are obligated to use commercially reasonable efforts to develop one licensed product and to commercialize and obtain regulatory approval 
for at least one licensed product in the United States and in specified European countries. 

All inventions, know-how, data and results resulting from our activities under the license agreement, including activities relating to our own clinical trials, will be 
exclusively owned by us. All inventions, know-how, data and results resulting from Novartis’ activities connected with Novartis’ ongoing Phase 1 clinical trial for 
IDE196 will be exclusively owned by Novartis, and subject to the license to us. Ownership of all other inventions and know-how will be determined according to U.S. 
patent law, with Novartis’ interest subject to the license to us.

We control the prosecution and maintenance of the patents exclusively licensed to us, with Novartis retaining step-in rights if we do not continue such prosecution and 
maintenance. If we fail to maintain or prosecute any exclusively licensed patent and Novartis exercises this step-in right, our license to the relevant patents will 
terminate in the relevant country. We have the first right to enforce any exclusively licensed patents, while Novartis retains the right to representation. If we do not bring 
an action to enforce any exclusively licensed patent, Novartis has the right to bring such action, and we will have the right to representation. 

We paid Novartis an upfront payment of $2.5 million and issued 263,615 shares of our Series B redeemable convertible preferred stock concurrently with the execution 
of the license agreement. Subject to completion of certain clinical and regulatory development milestones, we agreed to make milestone payments in the aggregate of 
up to $9.0 million, and subject to achievement of certain commercial sales milestones, we agreed to make milestone payments in the aggregate of up to $20.0 million. 
We also agreed to pay mid to high single-digit tiered royalty payments based on annual worldwide net sales of licensed products, payable on a licensed product-by-
licensed product and country by country basis until the latest of the expiration of the last to expire exclusively licensed patent, the expiration of regulatory exclusivity, 
and the ten year anniversary of the first commercial sale of such product in such country. The royalty payments are subject to reductions for lack of patent coverage, 
loss of market exclusivity, and payment obligations for third-party licenses. 

The license agreement continues in force on a licensed product-by-licensed product and country by country basis until the latest of the expiration of the last to expire 
exclusively licensed patent, the expiration of regulatory exclusivity, and the ten year anniversary of the first commercial sale of such product in such country. 

We may terminate the license agreement in its entirety or on a licensed product-by-licensed product basis without cause on 60 days’ prior written notice. Either party 
may terminate the license agreement for the other party’s material breach that remains uncured for 90 days. In addition, Novartis has the right to terminate the license 
agreement immediately upon our insolvency. 

22

 
 
 
 
 
 
 
 
 
 
 
Upon termination by Novartis for material breach or for our insolvency, or upon termination by us without cause, at Novartis’ written request and in return for 
consideration that will be negotiated at such time, we will grant to Novartis a perpetual, irrevocable, worldwide, sublicensable, nonexclusive or exclusive license, under 
all patent rights and know-how controlled by us that are related to and actually used as of the date of termination in the development, manufacture, and 
commercialization of licensed products, for Novartis to develop, manufacture, and commercialize the licensed products.

Clinical Trial Collaboration and Supply Agreement with Amgen for IDE397

In July 2022, we entered into the Amgen CTCSA to clinically evaluate IDE397 in combination with AMG 193 in patients having MTAP-null solid tumors, in a Phase 
1/2 clinical trial. Under the mutually non-exclusive Amgen CTCSA, we will provide IDE397 drug supply to Amgen, who will be the sponsor of the Phase 1 clinical 
combination trial evaluating IDE397 and AMG 193. Each party will pay for fifty percent (50%) of the external third-party costs of the combination study. Each party 
will be responsible for its own internal costs and expenses in support of the combination study. We and Amgen will jointly oversee clinical development of the 
combination therapy through a Joint Oversight Committee responsible for coordinating all regulatory and other activities under the Amgen CTCSA. The parties will 
jointly own collaboration data and combination-related intellectual property, if any, arising from the combination clinical trial. We and Amgen each retain commercial 
rights to our respective compounds, including with respect to use as a monotherapy agent or combination agent. 

Clinical Trial Collaboration and Supply Agreement with Gilead for IDE397

In November 2023, we entered into the Gilead CSCSA with Gilead to clinically evaluate IDE397 in combination with Trodelvy (sacituzumab-govitecan-hziy), a Trop-2 
directed ADC, in patients having MTAP-deletion bladder cancer, in a Phase 1 clinical trial. Under the mutually non-exclusive Gilead CSCSA, we will receive Trodelvy 
drug supply from Gilead and will sponsor the Phase 1 clinical combination trial evaluating ID397 and Trodelvy. Gilead will bear internal or external costs incurred in 
connection with its supply of Trodelvy. We will bear all internal and external costs and expenses associated with the conduct of the combination study. We and Gilead 
will jointly oversee clinical development of the combination therapy through a Joint Steering Committee responsible for coordinating all regulatory and other activities 
under the Gilead CSCSA. We and Gilead each retain commercial rights to our respective compounds, including with respect to use as a monotherapy agent or 
combination agent.

Exclusive Option and License Agreement with Cancer Research UK for IDE161

In April 2017, we entered into the CRUK/Manchester Agreement with Cancer Research UK and University of Manchester, which was amended on April 24, 2019 and 
on March 3, 2020, for the development and commercialization of licensed products comprising pharmaceutical preparations of PARG inhibitors for all therapeutic uses.

Under this agreement, Cancer Research UK and University of Manchester have granted to us, and we have in turn granted to Cancer Research UK and University of 
Manchester, non-exclusive, sublicensable, royalty-free licenses to carry out non-clinical research during the research term, which ended with our exercise of our option 
described below. The non-clinical research was governed by a joint research committee comprised of representatives from each party. During the research term, no 
party was to undertake a drug discovery program in PARG inhibitors other than under this agreement. 

Cancer Research UK also granted us the exclusive option to obtain an exclusive, sublicensable, worldwide, royalty-bearing license, under certain Cancer Research UK 
background intellectual property and Cancer Research UK’s interest in any intellectual property jointly developed under the agreement, to research, develop, 
manufacture, and commercialize licensed products, as well as a non-exclusive, sublicensable, royalty-free, freedom-to-operate license under related intellectual 
property. Cancer Research UK and University of Manchester retain certain rights under the licensed intellectual property for academic, non-commercial research and 
teaching. 

In the March 2020 second amendment to the CRUK/Manchester Agreement, the parties reduced the license fee due at exercise of our option, extended the research 
period to March 2021, and also extended the option period, during which we have rights to exercise an option to certain license rights. The expanded collaborative 
research included evaluation of an IDEAYA proprietary small molecule PARG inhibitor in multiple in vitro and in vivo ovarian cancer xenograft models. This research 
was also evaluating replication stress signature as a potential patient selection biomarker. The extended option period was for up to four additional years from March 

23

 
 
 
 
 
 
 
 
 
 
2020, including an initial one year period to March 2021 and an additional eighteen month extension to September 2022, which has now been elected pursuant to our 
certification of ongoing program research activities.

In January 2022, we exercised our option for an exclusive worldwide license rights covering a broad class of PARG inhibitors from Cancer Research Technology Ltd. 
(CRT) and the University of Manchester, and in connection therewith, paid a one-time option exercise fee of £250,000. 

Following our option exercise, we gained sole control and responsibility for the research, development, manufacture, and commercialization of the licensed PARG 
inhibitors. Cancer Research UK also transferred its know how relating to the research, development or manufacturing of the licensed PARG inhibitors to us. 

We were obligated to use reasonable efforts to research a PARG inhibitor during the research term, and we are obligated to develop a PARG inhibitor for the treatment 
of a cancer indication now that we exercised the option. 

Each party is the sole owner of any intellectual property it develops solely under the agreement, and the parties will be joint owners of any jointly developed intellectual 
property. Each party grants the other a non-exclusive, fully-paid, royalty free, irrevocable, sublicensable, perpetual license to its rights in such jointly created intellectual 
property to make, use and sell inventions claimed in the joint patents, except for those joint patents exclusively licensed to us under the agreement following our 
exercise of the option.

Before our exercise of the option, Cancer Research UK was responsible for the prosecution and maintenance of Cancer Research UK background patents specifically 
relating to PARG, while we were responsible for the prosecution and maintenance of patents covering inventions developed under the agreement as project intellectual 
property. Cancer Research UK and University of Manchester had the first right to enforce the patents covering inventions developed under the agreement as project 
intellectual property and we had the right to participate in such actions. 

Following our exercise of the option, we have assumed Cancer Research UK’s prosecution and maintenance responsibilities for the Cancer Research UK background 
patents specifically relating to PARG and we obtained the first right to enforce such patents as well as the patents covering inventions developed under the agreement as 
project intellectual property, and Cancer Research UK will have the right to participate. 

We pay all expenses associated with prosecution and maintenance and each party bears its own costs for enforcement. If we abandon the patents covering inventions 
developed under the agreement as project intellectual property, Cancer Research UK will thereafter be responsible for prosecuting and maintaining such patents. If we 
abandon such patents, Cancer Research UK and University of Manchester will be responsible for paying the expenses associated with the prosecution and maintenance 
of such patents. 

In addition to an upfront fee of £100,000 and a one-time option exercise fee of £250,000, each of which have been paid, we have certain potential milestone-dependent 
financial obligations, including: (a) subject to completion of specific development and regulatory approval events for development of a PARG inhibitor in oncologic 
diseases, payments of up to £19.5 million per broad disease classification block – for example, in oncologic diseases, up to £13.0 million aggregate for a first 
achievement of such clinical and regulatory milestones and up to £6.5 million aggregate for a second achievement of such clinical and regulatory milestones; (b) subject 
to certain sales-based milestones based on net sales of licensed products. payments of up to £9 million per broad disease classification block – for example, in oncologic 
diseases, up to £6.0 million aggregate for a first achievement of such sales milestones and up to £3.0 million aggregate for a second achievement of such sales 
milestones; and (c) low single-digit tiered royalty payments based on aggregate worldwide net sales of all products, payable on a product-by-product and country-by-
country basis until the later of the last-to-expire patent covering such product in such country and the ten year anniversary of the first commercial sale of such licensed 
product in such country.

The royalty payments are subject to reductions for payment obligations in the event third-party licenses are required to develop or commercialize the product or if the 
product is not covered by certain patents.

24

 
 
 
 
 
 
 
 
 
 
 
In April 2023, we incurred an obligation to pay milestone payments in an aggregate amount of £750,000 to CRT based upon the achievement of certain milestones 
relating to first and second tumor histologies in connection with the Phase 1 portion of the Phase 1/2 clinical trial in oncologic diseases. 

Certain of the clinical and regulatory milestones are related to and may be due and payable by us if certain milestones are achieved in connection with the IDE161-001 
Phase 1/2 clinical trial. We will be obligated to make future milestone payments to CRT aggregating up to £18.75 million upon the achievement of specific development 
and regulatory approval events for development of a PARG inhibitor in oncologic diseases, including an aggregate of up to £1.5 million and up to £2.25 for the 
achievement of certain Phase 2 and Phase 3 development milestones, respectively, in each case as relating to first (e.g., a breast cancer) and second (e.g., ovarian 
cancer) tumor histologies.

Following our exercise of the option, if we sublicense certain intellectual property developed under the agreement or Cancer Research UK background patents 
specifically relating to PARG, we will also have an obligation to pay to Cancer Research UK low double digit percentage of sublicense revenue we receive, if any. If the 
agreement is terminated due to our material breach, then we are eligible to receive a percentage of sublicensing revenue that Cancer Research UK receives for licensing 
intellectual property. 

If the agreement is terminated by Cancer Research UK and University of Manchester pursuant to any of their termination rights, then Cancer Research UK and 
University of Manchester will have exclusive, worldwide rights to project intellectual property. If we terminate the agreement for material breach, then the licenses we 
receive upon exercise of the option survive, and our payment obligations will be reduced. Following our exercise of the option, the licenses we receive upon exercise of 
the option survive expiration of the agreement. 

Collaboration, Option and License Agreement with GSK for Pol Theta and Werner Helicase 

In June 2020, we entered into the GSK Collaboration Agreement, with GSK, pursuant to which we and GSK have entered into a collaboration for its synthetic lethality 
programs targeting MAT2A, Pol Theta and Werner Helicase. On July 27, 2020, we and GSK received Hart-Scott-Rodino Antitrust Improvements Act clearance, or 
HSR Clearance, and the GSK Collaboration Agreement became effective. Pursuant to the GSK Collaboration Agreement, GSK paid the Company $100.0 million on 
July 31, 2020. As of December 31, 2023 GSK has made aggregate payments to us in the amount of $13.0 million for the achievement of certain development and 
regulatory milestones with respect to Pol Theta and WRN products.

GSK Collaboration – MAT2A Program

Under the MAT2A program, we led research and development through early clinical development stage, and GSK had an exclusive option to obtain an exclusive 
license to continue development of and commercialize MAT2A products arising out of the MAT2A program, or the Option. We delivered an Option data package 
resulting from our conduct of a dose escalation portion of a MAT2A Phase 1 monotherapy clinical trial pursuant to the GSK Collaboration Agreement, following which 
the Option was exercisable within a specified time period.

In January 2022, GSK waived its rights under the GSK Collaboration Agreement to initiate, or request that we initiate, prior to GSK’s exercise of the Option, a Phase 1 
combination clinical trial for a MAT2A product and GSK’s Type I PRMT inhibitor (GSK3368715) product, or the MAT2A Combination Trial. Accordingly, we have no 
further obligation under the GSK Collaboration Agreement to supply MAT2A product for the MAT2A Combination Trial at its own cost. Our obligation to supply the 
MAT2A compound for the MAT2A Combination Study was deemed a material right under the GSK Collaboration Agreement.

In August 2022, we received notice from GSK waiving its rights to exercise its Option, or the MAT2A Option Waiver, pursuant to the GSK Collaboration Agreement. 
As such, we retain and fully own all right, title and interest in and to IDE397 and the MAT2A program, including all worldwide commercial rights thereto. We will be 
responsible for the costs of further research and clinical development activities that we conduct for the MAT2A program following the MAT2A Option Waiver.

from high single-digit to sub-teen double-digit percentages, subject to certain customary reductions.

Under the terms of the GSK Collaboration Agreement, subject to certain exceptions, we and GSK will not, directly or through third parties, develop or commercialize 
other products whose primary and intended mechanism of action is the modulation of WRN or Pol Theta for an agreed upon period of time. We and GSK have formed a 
joint steering committee, joint development committees, and joint commercialization committees responsible for coordinating all activities under the GSK 
Collaboration Agreement. Ownership of intellectual property developed under the GSK Collaboration Agreement is allocated between or shared by the parties 
depending on development and subject matter.

GSK’s royalty obligations continue with respect to each country and each product until the later of (i) the date on which such product is no longer covered by certain 
intellectual property rights in such country and (ii) the 10th anniversary of the first commercial sale of such product in such country.

Each party has the right to sublicense its rights under the GSK Collaboration Agreement subject to certain conditions.

The GSK Collaboration Agreement will continue in effect on a product-by-product and country-by-country basis until the expiration of the obligation to make 
payments under the GSK Collaboration Agreement with respect to such product in each country, unless earlier terminated by either party pursuant to its terms. Either 
party may terminate the GSK Collaboration Agreement for the other party’s insolvency or certain uncured breaches. We may terminate the GSK Collaboration 
Agreement if GSK or any of its sublicensees or affiliates challenge certain patents of ours. GSK may terminate the GSK Collaboration Agreement in its entirety or on a 
target-by-target basis upon 90-day notice to us. 

Sales and Marketing 

We intend to become a fully-integrated biopharmaceutical company. This will enable us to realize our goal of delivering transformative drugs to patients. We currently 
hold worldwide commercialization rights to each of our product candidates, and intend to retain significant rights in key markets. In light of our stage of development, 
we have not yet established sales and marketing capabilities. We are planning for potential commercial operations, including for sales and marketing capabilities, 
subject to further process of our potentially registrational Phase 2/3 clinical trial for darovasertib. 

We plan to build our own sales force to commercialize approved products, if any, in the United States and potentially in Europe and other selected foreign countries, and 
we expect to initiate commercial readiness activities in anticipation of receiving marketing approvals. We believe a moderately sized specialty sales force would enable 
us to reach oncologists who specialize in treating the patient populations for our product candidates. We may enter into distribution and other marketing arrangements 
with third parties for any of our product candidates that obtain marketing approval. 

We also plan to build a marketing and sales management organization to create and implement marketing strategies for any products that we market through our own 
sales organization and to oversee and support our sales force. 

Manufacturing 

We currently rely, and expect to continue to rely, on third parties for the manufacture of our product candidates and our biomarker diagnostics for preclinical and 
clinical testing, as well as for future commercial manufacture of any drugs and diagnostics that we may commercialize. We do not own or operate, and currently have 
no plans to establish, any manufacturing facilities. 

In general, we plan to establish agreements with contract manufacturing organizations, or CMOs, for synthesis of the active pharmaceutical ingredient, or API, 
manufacturing of drug product comprising such API, as well as packaging, labeling and distribution.

27

 
 
 
 
 
 
 
 
 
 
 
 
We have also established supply arrangements with one or more CMOs for each of our development programs in support of our current clinical development needs. 

Our lead product candidates darovasertib, IDE397, IDE161 and Pol Theta are each small molecules that can be manufactured in reliable and reproducible synthetic 
processes from readily available starting materials. We believe the synthetic chemistry is amenable to scale-up using standard manufacturing equipment and processes. 
We expect that the compounds being discovered and developed for our other pipeline programs, including WRN, and other future programs, will also be small molecule 
product candidates that can be produced at contract manufacturing facilities. 

In many cases, we anticipate that the biomarker diagnostic may be commercially available on an existing third-party diagnostic panel or assay. In cases where such 
biomarker diagnostic is not already commercially available, we generally expect to establish agreements with strategic partners for clinical supply of companion 
diagnostics for biomarkers associated with the targeted therapeutics we are developing. 

Government Regulation 

Government authorities in the United States, at the federal, state and local level, and in other countries extensively regulate, among other things, the research, 
development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, marketing and export 
and import of products such as those we are developing. A new drug must be approved by the FDA through the NDA process before it may be legally marketed in the 
United States.

U.S. Drug Development Process 

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or the FDCA, and its implementing regulations. The process of 
obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of 
substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process 
or after approval may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, 
withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, 
refusals of government contracts, restitution, disgorgement or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect 
on us. 

The process required by the FDA before a drug may be marketed in the United States generally involves the following: 

•

•

•

•

•

•

•

completion of preclinical laboratory tests, animal studies and formulation studies in accordance with good laboratory practice, or GLP, regulations and 
other applicable regulations; 

submission to the FDA of an IND, which must become effective before clinical trials in humans may begin; 

approval by an independent institutional review board, or IRB, at each clinical site before each clinical trial may be initiated; 

performance of adequate and well-controlled human clinical trials in accordance with good clinical practice, or GCP, regulations to establish the safety 
and efficacy of the proposed drug for its intended use; 

submission to the FDA of an NDA; 

satisfactory completion of an FDA advisory committee review, if applicable; 

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with current 
good manufacturing practice, or cGMP, regulations to assure that the facilities, methods and controls are adequate to preserve the drug’s identity, 
strength, quality and purity; and 

28

 
 
 
 
 
 
•

FDA review and approval of the NDA. 

Once a pharmaceutical product candidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product 
chemistry, toxicity and formulation, as well as animal studies. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information 
and analytical data, to the FDA as part of the IND. The sponsor will also include a protocol detailing, among other things, the objectives of the first phase clinical trial, 
the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated, if the first phase lends itself to an efficacy evaluation. Some preclinical 
testing may continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day 
time period, places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can 
begin. A clinical hold also may be imposed by the FDA at any time during a clinical trial due to safety concerns or non-compliance with specific FDA requirements, 
and the clinical trial may not continue until the FDA notifies the sponsor that the hold has been lifted. 

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations, which include the requirement 
that all research subjects provide their informed consent in writing for their participation in any clinical trial. They must be conducted under protocols detailing the 
objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the safety and effectiveness criteria to be evaluated. Each protocol must be 
submitted to the FDA as part of the IND. An IRB at each institution participating in the clinical trial must review and approve each protocol before a clinical trial 
commences at that institution and must also approve the information regarding the clinical trial and the consent form that must be provided to each clinical trial subject 
or his or her legal representative, monitor the clinical trial until completed and otherwise comply with IRB regulations. 

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

•

•

•

Phase 1: The product candidate is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, 
distribution and excretion and, if possible, to gain an early indication of its effectiveness. In the case of some products for severe or life-threatening 
diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing 
is often conducted in patients. Sponsors sometimes designate their Phase 1 clinical trials as Phase 1a or Phase 1b. Phase 1b clinical trials are typically 
aimed at confirming dosing, pharmacokinetics and safety in a larger number of patients. Some Phase 1b studies evaluate biomarkers or surrogate 
markers that may be associated with efficacy in patients with specific types of diseases. 

Phase 2: This phase involves clinical trials in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate 
the efficacy of the product for specific targeted diseases and to determine dosage tolerance and appropriate dosage. 

Phase 3: Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population, generally at 
geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk-benefit ratio of the product candidate and 
provide, if appropriate, an adequate basis for product labeling. 

Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These clinical trials are used to gain additional 
experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as 
a condition of approval of an NDA. 

The FDA or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an 
unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance 
with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. In addition, some clinical trials are overseen by an independent 
group of qualified experts organized by the sponsor, known as a data safety monitoring board or committee. Depending on its charter, this group may determine whether 
a clinical trial may move forward at designated check points based on access to certain data from the clinical trial. 

During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to submission of an IND, at 
the end of Phase 2, and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share 

29

 
 
 
 
 
 
 
information about the data gathered to date, for the FDA to provide advice, and for the sponsor and the FDA to reach agreement on the next phase of development. 
Sponsors typically use the meetings at the end of the Phase 2 clinical trial to discuss Phase 2 clinical results and present plans for the pivotal Phase 3 clinical trials that 
they believe will support approval of the new drug. 

Concurrent with clinical trials, companies may conduct additional animal studies and also develop additional information about the chemistry and physical 
characteristics of the drug and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing 
process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing 
the identity, strength, quality and purity of the final drug. In addition, appropriate packaging must be selected and tested, and stability studies must be conducted to 
demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life. 

While the IND is active and before approval, progress reports summarizing the results of the clinical trials and nonclinical studies performed since the last progress 
report must be submitted at least annually to the FDA, and written IND safety reports must be submitted to the FDA and investigators for serious and unexpected 
suspected adverse events, findings from other studies suggesting a significant risk to humans exposed to the same or similar drugs, findings from animal or laboratory 
testing suggesting a significant risk to humans, and any clinically important increased incidence of a serious suspected adverse reaction compared to that listed in the 
protocol or investigator brochure. 

There are also requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries. Sponsors of certain clinical trials of 
FDA-regulated products are required to register and disclose specified clinical trial information, which is publicly available at www.clinicaltrials.gov. Information 
related to the product, patient population, phase of investigation, clinical trial sites and investigators and other aspects of the clinical trial is then made public as part of 
the registration. Sponsors are also obligated to discuss the results of their clinical trials after completion. Disclosure of the results of these clinical trials can be delayed 
until the new product or new indication being studied has been approved. 

U.S. Review and Approval Process 

The results of product development, preclinical and other non-clinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests 
conducted on the chemistry of the drug, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting approval to market the 
product. The submission of an NDA is subject to the payment of substantial user fees; a waiver of such fees may be obtained under certain limited circumstances. The 
FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant 
to assure and preserve the product’s identity, strength, quality and purity. The FDA conducts a preliminary review of all NDAs within the first 60 days after submission, 
before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA may request additional information rather 
than accept an NDA for filing. In this event, the NDA must be resubmitted with the additional information. The resubmitted application also is subject to review before 
the FDA accepts it for filing. Under the Prescription Drug User Fee Act, or PDUFA, the FDA has agreed to certain performance goals in the review of NDAs through a 
two-tiered classification system, standard review and priority review. According to the current PDUFA performance goals for new molecular entity NDAs, the FDA 
endeavors to review and act on applications within ten months of the 60-day filing date under standard review, and within six months of the 60-day filing date under 
priority review. 

The FDA may refer an application for a novel drug to an advisory committee. An advisory committee is a panel of independent experts, including clinicians and other 
scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not 
bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. Before approving an NDA, the 
FDA will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing 
processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. 
Additionally, before approving an NDA, the FDA may inspect one or more clinical trial sites to assure compliance with GCP requirements. 

30

 
 
 
 
 
 
 
 
After the FDA evaluates an NDA, it will issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with 
prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete and the application will not 
be approved in its present form. A Complete Response Letter usually describes the specific deficiencies in the NDA identified by the FDA and may require additional 
clinical data, such as an additional pivotal Phase 3 clinical trial or other significant and time-consuming requirements related to clinical trials, nonclinical studies or 
manufacturing. If a Complete Response Letter is issued, the sponsor must resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the 
application. Even if such data and information are submitted, the FDA may decide that the NDA does not satisfy the criteria for approval. 

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, 
which could restrict the commercial value of the product. In addition, the FDA may require a sponsor to conduct Phase 4 testing, which involves clinical trials designed 
to further assess a drug’s safety and effectiveness after NDA approval, and may require testing and surveillance programs to monitor the safety of approved products 
which have been commercialized. The FDA may also place other conditions on approval including the requirement for a risk evaluation and mitigation strategy, or 
REMS, to assure the safe use of the drug. If the FDA concludes a REMS is needed, the sponsor of the NDA must submit a proposed REMS. The FDA will not approve 
the NDA without an approved REMS, if required. A REMS could include medication guides, physician communication plans or elements to assure safe use, such as 
restricted distribution methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing could restrict the commercial 
promotion, distribution, prescription or dispensing of products. Marketing approval may be withdrawn for non-compliance with regulatory requirements or if problems 
occur following initial marketing. 

Pediatric Use 

Even when not pursuing a pediatric indication, under the Pediatric Research Equity Act, or PREA, an NDA or supplement thereto must contain data that is adequate to 
assess the safety and effectiveness of the drug product for the claimed indications in all relevant pediatric subpopulations, and to support dosing and administration for 
each pediatric subpopulation for which the product is safe and effective. In addition, any sponsor planning to submit an NDA or supplement subject to PREA must 
submit an initial pediatric study plan, or iPSP, to the IND early in development. The iPSP must contain an outline of the proposed pediatric trials the sponsor plans to 
conduct, including trial objectives and design, any deferral or waiver requests, and other information required by regulation. The FDA must then review the information 
submitted, consult with the sponsor, and agree upon a final plan. The FDA or the sponsor may request an amendment to the plan at any time. The FDA may, on its own 
initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults, or full or 
partial waivers from the pediatric data requirements.

Separately, the FDA may issue a Written Request for pediatric studies relating to a drug product if it has determined that information related to the use of the drug in the 
pediatric population may produce health benefits. If the sponsor conducts the studies pursuant to the Written Request and submits the study reports within the specified 
timeline, the drug may be entitled to pediatric exclusivity. Pediatric exclusivity is a type of non-patent marketing exclusivity which, if granted, provides for the 
attachment of an additional six months of marketing protection to the term of any existing exclusivity. Sponsors may submit a proposal asking the FDA to issue a 
Written Request for this purpose.

U.S. Orphan Drug Designation 

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is a disease or condition that 
affects fewer than 200,000 individuals in the United States or, if it affects more than 200,000 individuals in the United States, there is no reasonable expectation that the 
cost of developing and making the drug product available in the United States for the disease or condition will be recovered from sales of the product in the United 
States. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and 
its designated orphan use are disclosed publicly by the FDA. Orphan drug designation conveys certain financial incentives, including opportunities for grant funding, 
tax credits for certain clinical trial costs and certain user-fee waivers. Orphan designation does not convey any advantage in or shorten the duration of the regulatory 
review and approval process. 

31

 
 
 
 
 
 
If a product that has orphan drug designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is 
entitled to orphan drug exclusivity, which means that the FDA may not approve any other application to market the same drug for the same indication for seven years, 
except in limited circumstances, such as a subsequent product demonstration of clinical superiority to the product with orphan drug exclusivity. Competitors may 
receive approval of different drugs for the indication for which the orphan product has exclusivity or obtain approval for the same drug but for a different indication 
from that for which the orphan product has exclusivity. Our product candidates could also be blocked from approval if a competitor obtains approval of the same drug 
for the same rare disease or condition before we do. 

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. 
In addition, exclusive marketing rights in the United States may also be lost if the FDA later determines that the request for designation was materially defective or if 
the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

In April 2022, the FDA designated darovasertib as an orphan drug for the treatment of UM, including MUM, and we may seek orphan drug designation for additional 
product candidates in the future. Orphan drug designation does not guarantee that any product candidate will be approved for the designated rare disease or condition, if 
at all.

U.S. Expedited Development and Review Programs

The FDA offers a number of expedited development and review programs for qualifying product candidates intended to treat serious or life-threatening diseases or 
conditions.

New drug products are eligible for fast track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to 
address unmet medical needs for the disease or condition. Fast track designation applies to the combination of the product and the specific indication for which it is 
being studied. The sponsor of a fast track product has opportunities for frequent interactions with the review team during product development and, once an NDA is 
submitted, the product may be eligible for priority review. A fast track product may also be eligible for rolling review, where the FDA may consider for review sections 
of the NDA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA 
agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of 
the NDA. 

A product intended to treat a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation to expedite its development and 
review. A product can receive breakthrough therapy designation if preliminary clinical evidence indicates that the product may demonstrate substantial improvement 
over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation 
includes all of the fast track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment 
to expedite the development and review of the product, including involvement of senior managers. 

After an NDA is submitted for a product, including a product with a fast track designation and/or breakthrough therapy designation, the NDA may be eligible for 
priority review. A product is eligible for priority review if it has the potential to provide a significant improvement in the treatment or prevention of a serious disease or 
condition compared to marketed products. If the drug contains a new molecular entity, priority review designation means the FDA’s goal is to take an action on the 
marketing application within six months of the 60-day filing date, compared with ten months under standard review. 

Additionally, products studied for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated approval upon a 
determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured 
earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into 
account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of accelerated approval, the FDA will 
require the sponsor to perform one or more adequate and well-controlled post-marketing confirmatory trials to verify and describe the anticipated effect on irreversible 
morbidity or mortality or other clinical benefit. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, 
which could adversely impact the timing of the commercial launch of the product. The FDA may withdraw approval of a drug or indication approved under the 

32

 
 
 
 
 
 
 
 
 
 
accelerated approval pathway if a trial required to verify the predicted clinical benefit fails to verify such benefit or if the applicant fails to conduct any required post-
approval trial with due diligence. Recently, the Food and Drug Omnibus Reform Act, or FDORA, enacted as part of the year-end omnibus spending bill in December 
2022, included several reforms intended to expand the FDA’s ability to regulate products receiving accelerated approval, including by increasing the FDA’s oversight 
over the conduct of confirmatory trials; however, the ultimate impact of these reforms remains unclear.

Even if a product qualifies for one or more of these expedited development and review programs, the FDA may later decide that the product no longer meets the 
conditions for qualification or decide that the time period for FDA review or approval will not be shortened. In November 2022, the FDA granted fast track designation 
to darovasertib in combination with crizotinib for treatment of adult patients with MUM. We also expect to pursue breakthrough therapy designation and accelerated 
approval for darovasertib and may explore some of these opportunities for our other product candidates as appropriate. We received Fast Track Designation from the 
U.S. Food and Drug Administration, or FDA for IDE161 for ovarian cancer and breast cancer indications. 

U.S. Post-approval Requirements 

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory standards is not maintained or if problems occur after the product 
reaches the market. Later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the 
product from the market. After approval, some types of changes to the approved product, such as adding new indications, certain manufacturing changes and additional 
labeling claims, are subject to further FDA review and approval. Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs 
are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state 
agencies for compliance with cGMP regulations and other laws and regulations. In addition, the FDA may impose a number of post-approval requirements as a 
condition of approval of an NDA. For example, the FDA may require post-marketing testing, including Phase 4 clinical trials, and surveillance to further assess and 
monitor the product’s safety and effectiveness after commercialization. 

Any drug products manufactured or distributed by us or our partners pursuant to FDA approvals will be subject to continuing regulation by the FDA, including, among 
other things, record-keeping requirements, reporting of adverse experiences with the drug, providing the FDA with updated safety and efficacy information, drug 
sampling and distribution requirements, complying with certain electronic records and signature requirements, and complying with FDA promotion and advertising 
requirements. The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market and imposes 
requirements and restrictions on drug manufacturers, such as those related to direct-to-consumer advertising, the prohibition on promoting products for uses or in 
patient populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and 
promotional activities involving the internet. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may 
result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. Failure to comply with 
the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant or manufacturer to 
administrative or judicial civil or criminal sanctions and adverse publicity. FDA sanctions could include refusal to approve pending applications, withdrawal of an 
approval, clinical holds on post-approval clinical trials, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or 
distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement 
of profits, or civil or criminal penalties. 

U.S. Marketing Exclusivity 

Market exclusivity provisions under the FDCA can delay the submission or the approval of certain marketing applications. The FDCA provides a five-year period of 
non-patent marketing exclusivity within the United States to the first applicant to obtain approval of an NDA for a new chemical entity. A drug is a new chemical entity 
if the FDA has not previously approved any other drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. 
During the exclusivity period, the FDA may not approve or even accept for review an abbreviated new drug application, or ANDA, or an NDA submitted under Section 
505(b)(2) of the FDCA, or 505(b)(2) NDA, submitted by another company for another drug that contains the same active moiety. However, an application may be 
submitted after four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder. 

33

 
 
 
 
 
 
 
The FDCA alternatively provides three years of marketing exclusivity for a change to a previously approved drug, such as a new indication or condition of use, 
submitted in an NDA, or supplement to an existing NDA, if one or more new clinical investigations, other than bioavailability or bioequivalence studies, that were 
conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application. This three-year exclusivity covers only the 
modification for which the drug received approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs or 505(b)(2) 
NDAs for drugs containing the active agent for the original indication or condition of use. 

Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to 
conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness. 

Other types of non-patent exclusivity include seven-year orphan drug exclusivity and six-month pediatric exclusivity (each discussed above).

FDA Regulation of Companion Diagnostics 

We are collaborating or expect to collaborate with strategic partners or CROs to manufacture and supply in vitro diagnostics to identify patients with biomarkers 
associated with the targeted therapeutics we are developing. These diagnostics, often referred to as companion diagnostics, are regulated as medical devices. In the 
United States, the FDCA and its implementing regulations, and other federal and state statutes and regulations govern, among other things, medical device design and 
development, preclinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, storage, advertising and promotion, 
sales and distribution, export and import, and post-market surveillance.

Under the FDCA, medical devices are classified into one of three classes – Class I, Class II or Class III – depending on the degree of risk associated with each medical 
device and the extent of control needed to provide reasonable assurances with respect to safety and effectiveness. Class I devices are those for which safety and 
effectiveness can be reasonably assured by adherence to a set of regulations, referred to as General Controls, which require compliance with the applicable portions of 
the FDA’s Quality System Regulation, or QSR, facility registration and product listing, reporting of adverse events and malfunctions, and appropriate, truthful and non-
misleading labeling and promotional materials. Class II devices are those that are subject to the General Controls, as well as Special Controls, which can include 
performance standards, guidelines and postmarket surveillance. Most Class II devices are subject to premarket review and clearance by the FDA. Premarket review and 
clearance by the FDA is accomplished through the 510(k) premarket notification process. Under the 510(k) process, the manufacturer must submit to the FDA a 
premarket notification, demonstrating that the device is “substantially equivalent” to a predicate device. To be “substantially equivalent,” the proposed device must have 
the same intended use as the predicate device, and either have the same technological characteristics as the predicate device or have different technological 
characteristics and not raise different questions of safety or effectiveness than the predicate device. Class III devices include devices deemed by the FDA to pose the 
greatest risk such as life-supporting or life-sustaining devices, or implantable devices, in addition to new devices deemed not substantially equivalent following the 
510(k) process. The safety and effectiveness of Class III devices cannot be reasonably assured solely by the General Controls and Special Controls. Therefore, these 
devices are generally subject to the premarket approval, or PMA, application process, which is generally more costly and time-consuming than the 510(k) process. 

Alternatively, a device might be the subject of a de novo classification request, which seeks marketing authorization and reclassification as a lower-risk Class I or Class 
II device for a new device that otherwise would automatically be regulated as a Class III device requiring a PMA approval. Specifically, medical device types that the 
FDA has not previously classified as Class I, II or III are automatically classified into Class III regardless of the level of risk they pose. The Food and Drug 
Administration Modernization Act of 1997 established a new route to market for low to moderate risk medical devices that are automatically placed into Class III due to 
the absence of a predicate device, called the “Request for Evaluation of Automatic Class III Designation,” or the de novo classification procedure. This procedure 
allows a manufacturer whose novel device is automatically classified into Class III to request down-classification of its medical device into Class I or Class II on the 
basis that the device presents low or moderate risk, rather than requiring the submission and approval of a PMA application. 

If the use of a companion diagnostic is essential to the safe and effective use of a drug or biologic product, then the FDA generally will require approval or clearance of 
the diagnostic contemporaneously with the approval of the therapeutic product. In July 2014, the FDA issued a final guidance document addressing the development 
and approval process for in vitro companion diagnostic devices. According to the guidance, for novel product candidates such as ours, a companion diagnostic device 
and its 

34

 
 
 
 
 
 
 
 
 
corresponding drug or biologic candidate should be approved or cleared contemporaneously by the FDA for the use indicated in the therapeutic product labeling. The 
guidance also explains that a companion diagnostic device used to make treatment decisions in clinical trials of a drug generally will be considered an investigational 
device, unless it is employed for an intended use for which the device is already approved or cleared. If used to make critical treatment decisions, such as patient 
selection, the diagnostic device generally will be considered a significant risk device under the FDA’s Investigational Device Exemption, or IDE, regulations. Thus, the 
sponsor of the diagnostic device will be required to comply with the IDE regulations. According to the guidance, if a diagnostic device and a drug are to be studied 
together to support their respective approvals, both products can be studied in the same investigational study, if the study meets both the requirements of the IDE 
regulations and the IND regulations. The guidance provides that depending on the details of the study plan and subjects, a sponsor may seek to submit an IND alone, or 
both an IND and an IDE. In July 2016, the FDA issued a draft guidance document intended to further assist sponsors of therapeutic products and sponsors of in vitro 
companion diagnostic devices on issues related to co-development of these products. In December 2018, the FDA issued another draft guidance document to facilitate 
class labeling on in vitro companion diagnostic devices for oncology therapeutic products, under which a companion diagnostic’s labeling may identify a specific group 
or class of therapeutic products, rather than specific products, where scientifically appropriate. 

The FDA generally requires companion diagnostics intended to select the patients who will respond to cancer treatment to obtain approval of a PMA for that diagnostic 
contemporaneously with approval of the therapeutic, though 510(k) clearance or grant of a de novo classification request are also possible. The review of these in vitro 
companion diagnostics in conjunction with the review of a cancer therapeutic involves coordination of review by the FDA’s Center for Biologics Evaluation and 
Research or Center for Drug Evaluation and Research and by the FDA’s Center for Devices and Radiological Health. The PMA process, including the gathering of 
clinical and preclinical data and the submission to and review by the FDA, can take several years or longer. It involves a rigorous premarket review during which the 
applicant must prepare and provide the FDA with reasonable assurance of the device’s safety and effectiveness and information about the device and its components 
regarding, among other things, device design, manufacturing and labeling. PMA applications are subject to an application fee. In addition, PMAs for certain devices 
must generally include the results from extensive preclinical and adequate and well-controlled clinical trials to establish the safety and effectiveness of the device for 
each indication for which FDA approval is sought. In particular, for a diagnostic, the applicant must demonstrate that the diagnostic produces reproducible results when 
the same sample is tested multiple times by multiple users at multiple laboratories. As part of the PMA review, the FDA will typically inspect the manufacturer’s 
facilities for compliance with the QSR, which imposes elaborate testing, control, documentation and other quality assurance requirements. 

If the FDA evaluations of both the PMA application and the manufacturing facilities are favorable, the FDA will either issue an approval letter or an approvable letter, 
which usually contains a number of conditions that must be met in order to secure the final approval of the PMA, such as changes in labeling, or specific additional 
information, such as submission of final labeling, in order to secure final approval of the PMA. If the FDA concludes that the applicable criteria have been met, the 
FDA will issue a PMA for the approved indications, which can be more limited than those originally sought by the applicant. The PMA can include post-approval 
conditions that the FDA believes necessary to ensure the safety and effectiveness of the device, including, among other things, restrictions on labeling, promotion, sale 
and distribution. 

If the FDA’s evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a not approvable letter. A not 
approvable letter will outline the deficiencies in the application and, where practical, will identify what is necessary to make the PMA approvable. The FDA may also 
determine that additional clinical trials are necessary, in which case the PMA approval may be delayed for several months or years while the clinical trials are conducted 
and then the data submitted in an amendment to the PMA. Once granted, PMA approval may be withdrawn by the FDA if compliance with post approval requirements, 
conditions of approval or other regulatory standards is not maintained or problems are identified following initial marketing. PMA approval is not guaranteed, and the 
FDA may ultimately respond to a PMA submission with a not approvable determination based on deficiencies in the application and require additional clinical trials or 
other data that may be expensive and time-consuming to generate and that can substantially delay approval. 

If a companion diagnostic is the subject of a de novo classification request in lieu of a PMA, the FDA is required to classify the device within 120 days following 
receipt of the de novo submission. If the manufacturer seeks reclassification into Class II, the manufacturer must include a draft proposal for special controls that are 
necessary to provide a reasonable assurance of the safety and effectiveness of the medical device. The FDA may reject the reclassification petition if it identifies a 
legally marketed predicate device that would be appropriate for a 510(k) or determines that the device is not low to moderate risk or that general controls would be 
inadequate to control the risks and special controls cannot be developed. If the de novo request is granted, the new device may be legally marketed (in compliance with 
applicable regulatory controls), a new classification regulation for the device type will be established, and the device may serve as a predicate device for 510(k) 
submissions for future devices of the same type. 

35

 
 
 
 
 
 
After a device is placed on the market, it remains subject to significant regulatory requirements. Medical devices may be marketed only for the uses and indications for 
which they are cleared or approved. Device manufacturers must also establish registration and device listings with the FDA. A medical device manufacturer’s 
manufacturing processes and those of its suppliers are required to comply with the applicable portions of the QSR, which cover the methods and documentation of the 
design, testing, production, processes, controls, quality assurance, labeling, packaging and shipping of medical devices. Domestic facility records and manufacturing 
processes are subject to periodic unscheduled inspections by the FDA. The FDA also may inspect foreign facilities that export products to the United States. 

Regulation Outside the United States 

To the extent that any of our product candidates, once approved, are sold in a foreign country, we would be subject to numerous and varying foreign laws and 
regulations regarding safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our products, 
and may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws and implementation of corporate 
compliance programs and reporting of payments or other transfers of value to healthcare professionals. The foreign regulatory approval process includes all of the risks 
associated with FDA approval set forth above, as well as additional country-specific regulation.

Whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign countries before we 
can commence clinical trials or marketing of the product in those countries. Approval by one regulatory authority does not ensure approval by regulatory authorities in 
other jurisdictions. The approval process varies from country to country, can involve additional testing beyond that required by FDA, and may be longer or shorter than 
that required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing, promotion, and reimbursement vary greatly from 
country to country.

Non-clinical Studies and Clinical Trials 

Similarly to the United States, the various phases of non-clinical and clinical research in the European Union, or EU, are subject to significant regulatory controls. 

Non-clinical studies are performed to demonstrate the health or environmental safety of new chemical or biological substances. Non-clinical (pharmaco-toxicological) 
studies must be conducted in compliance with the principles of good laboratory practice, or GLP, as set forth in EU Directive 2004/10/EC (unless otherwise justified for 
certain particular medicinal products, e.g., radio-pharmaceutical precursors for radio-labeling purposes). In particular, non-clinical studies, both in vitro and in vivo, 
must be planned, performed, monitored, recorded, reported and archived in accordance with the GLP principles, which define a set of rules and criteria for a quality 
system for the organizational process and the conditions for non-clinical studies. These GLP standards reflect the Organization for Economic Co-operation and 
Development requirements. 

Clinical trials of medicinal products in the EU must be conducted in accordance with EU and national regulations and the International Council for Harmonization of 
Technical Requirements for Pharmaceuticals for Human Use, or ICH, guidelines on Good Clinical Practices, or GCP, as well as the applicable regulatory requirements 
and the ethical principles that have their origin in the Declaration of Helsinki. If the sponsor of the clinical trial is not established within the EU, it must appoint an EU 
entity to act as its legal representative. The sponsor must take out a clinical trial insurance policy, and in most EU member states, the sponsor is liable to provide ‘no 
fault’ compensation to any study subject injured in the clinical trial. 

The regulatory landscape related to clinical trials in the EU has been subject to recent changes. The EU Clinical Trials Regulation, or CTR, which was adopted in April 
2014 and repeals the EU Clinical Trials Directive, became applicable on January 31, 2022. Unlike directives, the CTR is directly applicable in all EU member states 
without the need for member states to further implement it into national law. The CTR notably harmonizes the assessment and supervision processes for clinical trials 
throughout the EU via a Clinical Trials Information System, which contains a centralized EU portal and database. 

While the EU Clinical Trials Directive required a separate clinical trial application, or CTA, to be submitted in each member state in which the clinical trial takes place, 
to both the competent national health authority and an independent ethics committee, much like the FDA and IRB respectively, the CTR introduces a centralized 
process and only requires the submission of a single application for multi-center trials. The CTR allows sponsors to make a single submission to both the competent 
authority and an ethics committee in each member state, leading to a single decision per member state. The CTA must include, among other things, a copy of the trial 
protocol and an 

36

 
 
 
 
 
 
 
 
 
 
 
investigational medicinal product dossier containing information about the manufacture and quality of the medicinal product under investigation. The assessment 
procedure of the CTA has been harmonized as well, including a joint assessment by all member states concerned, and a separate assessment by each member state with 
respect to specific requirements related to its own territory, including ethics rules. Each member state’s decision is communicated to the sponsor via the centralized EU 
portal. Once the CTA is approved, clinical study development may proceed. 

The CTR foresees a three-year transition period. The extent to which ongoing and new clinical trials will be governed by the CTR varies. Clinical trials for which an 
application was submitted (i) prior to January 31, 2022 under the EU Clinical Trials Directive, or (ii) between January 31, 2022 and January 31, 2023 and for which the 
sponsor has opted for the application of the EU Clinical Trials Directive remain governed by said Directive until January 31, 2025. After this date, all clinical trials 
(including those which are ongoing) will become subject to the provisions of the CTR.

Medicines used in clinical trials must be manufactured in accordance with Good Manufacturing Practice, or GMP. Other national and EU-wide regulatory requirements 
may also apply.

Marketing Authorization

In order to market our future products in the EU and many other foreign jurisdictions, we must obtain separate regulatory approvals. More concretely, in the EU, 
medicinal product candidates can only be commercialized after obtaining a marketing authorization, or MA. To obtain regulatory approval of a product candidate under 
EU regulatory systems, we must submit a MA application, or MAA. There are two types of MAs: 

•

•

“Centralized MAs” are issued by the European Commission through the centralized procedure based on the opinion of the Committee for Medicinal 
Products for Human Use, or CHMP of the European Medicines Agency, or EMA, and are valid throughout the entire territory of the EU. The centralized 
procedure is mandatory for certain types of medicinal products, such as (i) medicinal products derived from biotechnological processes, (ii) designated 
orphan medicinal products, (iii) advanced therapy medicinal products, or ATMPs (such as gene therapy, somatic cell therapy and tissue engineered 
products) and (iv) medicinal products containing a new active substance indicated for the treatment of certain diseases, such as AIDS/HIV, cancer, 
neurodegenerative disorders, diabetes, auto-immune and viral diseases and other immune dysfunctions. The centralized procedure is optional for 
products containing a new active substance not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical 
innovation or which are in the interest of public health in the EU; and 

“National MAs” are issued by the competent authorities of the EU member states, only cover their respective territory, and are available for products not 
falling within the mandatory scope of the centralized procedure. Where a product has already been authorized for marketing in an EU member states, 
this national MA can be recognized in another member state through the mutual recognition procedure. If the product has not received a national MA in 
any member state at the time of application, it can be approved simultaneously in various member state through the decentralized procedure. Under the 
decentralized procedure an identical dossier is submitted to the competent authorities of each of the member states in which the MA is sought, one of 
which is selected by the applicant as the reference member state. 

Under the centralized procedure the maximum timeframe for the evaluation of an MAA by the EMA is 210 days, excluding clock stops.

In exceptional cases, the CHMP might perform an accelerated review of a MAA in no more than 150 days (not including clock stops). Innovative products that target an 
unmet medical need and are expected to be of major public health interest may be eligible for a number of expedited development and review programs, such as the 
PRIority MEdicines, or PRIME, scheme, which provides incentives similar to the breakthrough therapy designation in the U.S. In March 2016, the EMA launched an 
initiative, the PRIME scheme, a voluntary scheme aimed at enhancing the EMA’s support for the development of medicines that target unmet medical needs. It is based 
on increased interaction and early dialogue with companies developing promising medicines, to optimize their product development plans and speed up their evaluation 
to help them reach patients earlier. Product developers that benefit from PRIME designation can expect to be eligible for accelerated assessment but this is not 
guaranteed. Many benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with 
the EMA, frequent discussions on clinical trial designs and other development program elements, and accelerated MAA assessment once a dossier has been submitted. 
Importantly, a dedicated contact and rapporteur from the CHMP is appointed early in the PRIME scheme facilitating increased understanding of the product at EMA’s 

37

 
 
 
 
 
 
 
committee level. An initial meeting initiates these relationships and includes a team of multidisciplinary experts at the EMA to provide guidance on the overall 
development and regulatory strategies.

Moreover, in the EU, a “conditional” MA may be granted in cases where all the required safety and efficacy data are not yet available. The conditional MA is subject to 
conditions to be fulfilled for generating the missing data or ensuring increased safety measures. It is valid for one year and has to be renewed annually until fulfillment 
of all the conditions. Once the pending studies are provided, it can become a “standard” MA. However, if the conditions are not fulfilled within the timeframe set by the 
EMA, the MA ceases to be renewed. Furthermore, MA may also be granted “under exceptional circumstances” when the applicant can show that it is unable to provide 
comprehensive data on the efficacy and safety under normal conditions of use even after the product has been authorized and subject to specific procedures being 
introduced. This may arise in particular when the intended indications are very rare and, in the present state of scientific knowledge, it is not possible to provide 
comprehensive information data on the efficacy and safety under normal conditions of use even after the product has been authorized and subject to specific procedures 
being introduced. This may arise in particular when the intended indications are very rare and, in the present state of scientific knowledge, it is not possible to provide 
comprehensive information, or when generating data may be contrary to generally accepted ethical principles. This MA is close to the conditional MA as it is reserved 
to medicinal products to be approved for severe diseases or unmet medical needs and the applicant does not hold the complete data set legally required for the grant of a 
MA. However, unlike the conditional MA, the applicant does not have to provide the missing data and will never have to. Although the MA “under exceptional 
circumstances” is granted definitively, the risk-benefit balance of the medicinal product is reviewed annually and the MA is withdrawn in case the risk-benefit ratio is 
no longer favorable.

Under the above described procedures, before granting the MA, the EMA or the competent authorities of the EU member states make an assessment of the risk-benefit 
balance of the product on the basis of scientific criteria concerning its quality, safety and efficacy. MAs have an initial duration of five years. After these five years, the 
authorization may be renewed on the basis of a reevaluation of the risk-benefit balance.

Data and Marketing Exclusivity 

In the EU, new products authorized for marketing, or reference products, generally receive eight years of data exclusivity and an additional two years of market 
exclusivity upon MA. If granted, the data exclusivity period prevents generic or biosimilar applicants from relying on the preclinical and clinical trial data contained in 
the dossier of the reference product when applying for a generic or biosimilar MA in the EU during a period of eight years from the date on which the reference product 
was first authorized in the EU. The market exclusivity period prevents a successful generic or biosimilar applicant from commercializing its product in the EU until 10 
years have elapsed from the initial MA of the reference product in the EU. The overall 10-year market exclusivity period can be extended to a maximum of eleven years 
if, during the first eight years of those 10 years, the MA holder obtains an authorization for one or more new therapeutic indications which, during the scientific 
evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. However, there is no guarantee that a product 
will be considered by the EU’s regulatory authorities to be a new chemical or biological entity, and products may not qualify for data exclusivity.

Pediatric Development

In the EEA, MAAs for new medicinal products have to include the results of studies conducted in the pediatric population, in compliance with a pediatric investigation 
plan, or PIP, agreed with the EMA’s Pediatric Committee, or PDCO. The PIP sets out the timing and measures proposed to generate data to support a pediatric 
indication of the drug for which MA is being sought. The PDCO can grant a deferral of the obligation to implement some or all of the measures of the PIP until there 
are sufficient data to demonstrate the efficacy and safety of the product in adults. Further, the obligation to provide pediatric clinical trial data can be waived by the 
PDCO when these data are not needed or appropriate because the product is likely to be ineffective or unsafe in children, the disease or condition for which the product 
is intended occurs only in adult populations, or when the product does not represent a significant therapeutic benefit over existing treatments for pediatric patients. Once 
the MA is obtained in all EU member states and study results are included in the product information, even when negative, the product is eligible for six months’ 
supplementary protection certificate extension (if any is in effect at the time of approval) or, in the case of orphan pharmaceutical products, a two year extension of the 
orphan market exclusivity is granted. 

Orphan Medicinal Products 

38

 
 
 
 
 
 
 
 
 
The criteria for designating an “orphan medicinal product” in the EU are similar in principle to those in the United States. A medicinal product can be designated as an 
orphan if its sponsor can establish that: (1) the product is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; 
(2) either (a) such condition affects not more than five in ten thousand persons in the EU when the application is made, or (b) the product, without the benefits derived 
from the orphan status, would not generate sufficient return to justify the necessary investment; and (3) there exists no satisfactory method of diagnosis, prevention or 
treatment of the condition in question that has been authorized for marketing in the EU or, if such method exists, the drug will be of significant benefit to those affected 
by that condition. 

In the EU, an application for designation as an orphan product can be made any time prior to the filing of a MAA. An EU orphan designation entitles a party to 
incentives such as reduction of fees or fee waivers, protocol assistance, and access to the centralized procedure. Upon grant of a MA, orphan medicinal products are 
entitled to a ten-year period of market exclusivity for the approved indication. During this market exclusivity period, competent authorities cannot accept another MAA, 
or grant a MA, or accept an application to extend a MA for a similar medicinal product for the same indication. The period of market exclusivity is extended by two 
years for orphan medicines that have also complied with an agreed PIP. No extension to any supplementary protection certificate can be granted on the basis of pediatric 
studies for orphan indications. Orphan designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The orphan exclusivity period may, however, be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for 
orphan designation, for example because the product is sufficiently profitable not to justify market exclusivity, or where the prevalence of the condition has increased 
above the threshold. Additionally, MA may be granted to a similar product for the same indication at any time if (i) the applicant consents to a second orphan medicinal 
product application, (ii) the applicant cannot supply sufficient quantities of the product, or (iii) the second applicant can establish that its product, although similar, is 
safer, more effective or otherwise clinically superior.

The aforementioned EU rules are generally applicable in the European Economic Area, or EEA, which consists of the 27 EU member states plus Norway, Liechtenstein 
and Iceland.

Failure to comply with EU and member state laws that apply to the conduct of clinical trials, manufacturing approval, MA of medicinal products and marketing of such 
products, both before and after grant of the MA, manufacturing of pharmaceutical products, statutory health insurance, bribery and anti-corruption or with other 
applicable regulatory requirements may result in administrative, civil or criminal penalties. These penalties could include delays or refusal to authorize the conduct of 
clinical trials, or to grant MA, product withdrawals and recalls, product seizures, suspension, withdrawal or variation of the MA, total or partial suspension of 
production, distribution, manufacturing or clinical trials, operating restrictions, injunctions, suspension of licenses, fines and criminal penalties. 

Regulation of Companion Diagnostics 

In the EU, in vitro diagnostic medical devices, or IVD MDs, were regulated by the EU Directive on in vitro diagnostic medical devices (Directive No. 98/79/EC, as 
amended), or IVDD, which regulated the placing on the market, the CE marking, the essential requirements, the conformity assessment procedures, the registration 
obligations for manufacturers and devices as well as the vigilance procedure. IVD MDs had to comply with the requirements provided for in the IVDD, and with further 
requirements implemented at national level (as the case may be).

The regulation of companion diagnostics is subject to further requirements since Regulation (EU) No 2017/746, or IVDR, became applicable on May 26, 2022 but there 
is a tiered system extending the grace period for many devices (depending on their risk classification) before they have to be fully compliant with the Regulation. The 
IVDR introduced a new classification system for companion diagnostics which are now specifically defined as diagnostic tests that support the safe and effective use of 
a specific medicinal product, by identifying patients that are suitable or unsuitable for treatment. Companion diagnostics will have to undergo a conformity assessment 
by a notified body. Before it can issue an EU certificate, the notified body must seek a scientific opinion from the EMA on the suitability of the companion diagnostic to 
the medicinal product concerned if the medicinal product falls exclusively within the scope of the centralized procedure for the authorization of medicines, or the 
medicinal 

39

 
 
 
 
 
 
 
 
product is already authorized through the centralized procedure, or a MAA for the medicinal product has been submitted through the centralized procedure. For other 
substances, the notified body can seek the opinion from a national competent authorities or the EMA.

The aforementioned EU rules are generally applicable in the EEA.

Healthcare Reform 

In the United States and certain foreign jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the 
healthcare system that could affect our future results of operations as we begin to directly commercialize our products. In March 2010, the Patient Protection and 
Affordable Care Act, or ACA, was signed into law which substantially changed the way healthcare is financed by both governmental and private insurers in the United 
States and significantly affected the pharmaceutical industry. The ACA contains a number of provisions, including those governing enrollment in federal healthcare 
programs, reimbursement adjustments and fraud and abuse changes. Additionally, the ACA increases the minimum level of Medicaid rebates payable by manufacturers 
of brand name drugs from 15.1% to 23.1%; requires collection of rebates for drugs paid by Medicaid managed care organizations; requires manufacturers to participate 
in a coverage gap discount program, under which they must agree to offer 70 percent point-of-sale discounts off negotiated prices of applicable brand drugs to eligible 
beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; imposes a non-deductible 
annual fee on pharmaceutical manufacturers or importers who sell “branded prescription drugs” to specified federal government programs, implemented a new 
methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted, 
or injected, expands of eligibility criteria for Medicaid programs, creates a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and 
conduct comparative clinical effectiveness research, along with funding for such research and establishes a Center for Medicare and Medicaid Innovation at CMS to test 
innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending.

Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court 
dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the U.S. 
Supreme Court’s decision, President Biden issued an executive order initiating a special enrollment period from February 15, 2021 through August 15, 2021 for 
purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and 
reconsider their existing policies and rules that limit access to healthcare. 

Other legislative changes have been proposed and adopted since the ACA was enacted, including aggregate reductions of Medicare payments to providers, which will 
remain in effect through 2032, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022, unless additional Congressional action is 
taken. In addition, on March 11, 2021, the American Rescue Plan Act of 2021 was signed into law, which eliminates the statutory Medicaid drug rebate cap, beginning 
January 1, 2024. The rebate was previously capped at 100% of a drug’s average manufacturer price.

Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted 
in several Congressional inquiries and proposed and enacted legislation designed, among other things, to bring more transparency to product pricing, review the 
relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for drug products. On August 16, 2022, 
the Inflation Reduction Act of 2022, or IRA, was signed into law. Among other things, the IRA requires manufacturers of certain drugs to engage in price negotiations 
with Medicare (beginning in 2026), imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation (first due in 2023), 
and replaces the Part D coverage gap discount program with a new discounting program (beginning in 2025). The IRA permits the Secretary of the Department of 
Health and Human Services to implement many of these provisions through guidance, as opposed to regulation, for the initial years. On August 29, 2023, HHS 
announced the list of the first ten drugs that will be subject to price negotiations, although the drug price negotiation program is currently subject to legal challenges. 
For that and other reasons, it is currently unclear how the IRA will be effectuated. Individual states in the United States have also become increasingly active in 
implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain 
product access and marketing cost disclosure and transparency measures and, in some cases, mechanisms to encourage importation from other countries and bulk 
purchasing.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state 
governments will pay for healthcare product candidates and services, which could result in reduced demand for our product candidates once approved or additional 
pricing pressures.

40

 
 
 
 
 
 
 
 
In the EU, similar developments may affect our ability to profitably commercialize our products, if approved. On December 13, 2021, Regulation No 2021/2282 on 
Health Technology Assessment, or HTA, amending Directive 2011/24/EU, was adopted. While the Regulation entered into force in January 2022, it will only begin to 
apply from January 2025 onwards, with preparatory and implementation-related steps to take place in the interim. Once applicable, it will have a phased 
implementation depending on the concerned products. The Regulation intends to boost cooperation among EU member states in assessing health technologies, 
including new medicinal products as well as certain high-risk medical devices, and provide the basis for cooperation at the EU level for joint clinical assessments in 
these areas. It will permit EU member states to use common HTA tools, methodologies, and procedures across the EU, working together in four main areas, including 
joint clinical assessment of the innovative health technologies with the highest potential impact for patients, joint scientific consultations whereby developers can seek 
advice from HTA authorities, identification of emerging health technologies to identify promising technologies early, and continuing voluntary cooperation in other 
areas. Individual EU member states will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technology, and making 
decisions on pricing and reimbursement.

Other Healthcare Laws 

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign 
jurisdictions in which they conduct their business. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, and transparency 
laws and regulations with respect to drug pricing and payments and other transfers of value to physicians and other healthcare providers, as well as similar foreign laws 
in the jurisdictions outside the United States. If their operations are found to be in violation of any of such laws or any other governmental regulations that apply, they 
may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, additional reporting obligations and oversight if we become 
subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, the curtailment or restructuring of operations, 
exclusion from participation in governmental healthcare programs and imprisonment. 

Data Privacy and Security Laws 

Pharmaceutical companies may be subject to numerous federal, state, and foreign laws, regulations and standards which govern the collection, use, disclosure and 
protection of health-related and other personal information, and could apply now or in the future to our operations or the operations of our partners. In the United States, 
numerous federal and state laws and regulations, including data breach notification laws, health information privacy and security laws and consumer protection laws 
and regulations govern the collection, use, disclosure, and protection of health-related and other personal information. In addition, certain foreign laws govern the 
privacy and security of personal data, including health-related data. Privacy and security laws, regulations, and other obligations are constantly evolving, may conflict 
with each other to complicate compliance efforts, and can result in investigations, proceedings, or actions that lead to significant civil and/or criminal penalties and 
restrictions on data processing.

Coverage and Reimbursement 

Sales of any product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state and foreign government healthcare 
programs, commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Decisions regarding the 
extent of coverage and amount of reimbursement to be provided are made on a plan-by-plan basis. These third-party payors are increasingly reducing reimbursements 
for medical products, drugs and services. In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost-containment 
programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products. Adoption of price controls and 
cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. 
Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a product could reduce physician usage and patient demand for 
the product and also have a material adverse effect on sales.

In addition, in many countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing and 
reimbursement vary widely from country to country. In the EU, governments influence the price of products through their pricing and reimbursement rules and control 
of national healthcare systems that fund a large part of the cost of those products to consumers. Member states are free to restrict the range of pharmaceutical products 
for which their national health insurance systems provide reimbursement, and to control the prices and reimbursement levels of pharmaceutical products for human use. 
Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed to by the 
government. Member states may approve a specific price or level of reimbursement for the pharmaceutical product, or alternatively adopt a system of direct or indirect 
controls on the profitability of the company responsible for placing the pharmaceutical product on the market, including volume-based arrangements, caps and reference 
pricing mechanisms. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost 
effectiveness of a particular product to currently available therapies. Other member states allow companies to fix their own prices for medicines, but monitor and 
control company profits. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow 
favorable reimbursement and pricing arrangements for any of our products. The downward pressure on healthcare costs in general, particularly prescription products, 
has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross border imports from 
low-priced markets exert a commercial pressure on pricing within a country.

We may face competition for our product candidates from lower-priced products in foreign countries that have placed price controls on pharmaceutical products. In 
addition, there may be importation of foreign products that compete with our own products, which could negatively impact our profitability. Furthermore, there can be 
no assurance that our products will be considered medically reasonable and necessary for a specific indication, that our products will be considered cost-effective by 
third-party payors, that an adequate level of reimbursement will be established even if coverage is available or that the third-party payors’ reimbursement policies will 
not adversely affect our ability to sell our products profitably.

Item 1A. Risk Factors. 

Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, as well as the other information in this Annual 
Report on Form 10-K, including our financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations,” before deciding whether to invest in our common stock. The occurrence of any of the events or developments described below could harm our business, 
financial condition, results of operations, growth prospects and stock price. In such an event, the market price of our common stock could decline, and you may lose all 
or part of your investment. Many of the following risks and uncertainties are, and will be, exacerbated by the COVID-19 pandemic, the ongoing Ukraine-Russia 
conflict, the Israel Hamas conflict, or banking sector volatility and any worsening of the global business and economic environment as a result. Additional risks and 
uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations.

Risks Related to Our Limited Operating History, Financial Condition and Capital Requirements 

We are an early-stage biopharmaceutical company with a limited operating history and no products approved for commercial sale. We have incurred significant 
losses since our inception, and we anticipate that we will continue to incur significant losses for the foreseeable future, which, together with our limited operating 
history, makes it difficult to assess our future viability. 

Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. We are an early-stage biopharmaceutical 
company, and we have only a limited operating history upon which you can evaluate our business and prospects. We currently have no products approved for 
commercial sale, have not generated any revenue from sales of products and have incurred losses in each year since our inception in June 2015. In addition, we have 
limited experience as a company and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by 
companies in new and rapidly evolving fields, particularly in the biopharmaceutical industry. Four of our product candidates, IDE397, darovasertib (IDE196), IDE161 
and GSK101 (being developed by GSK under the Collaboration, Option and License Agreement with GSK), are currently in ongoing clinical trials.

We have had significant operating losses since our inception. Our net losses for the twelve months ended December 31, 2023 and 2022 were $113.0 million and $58.7 
million, respectively. As of December 31, 2023, we had an accumulated deficit of $348.4 million. Substantially all of our losses have resulted from expenses incurred in 
connection with our research and development programs and from general and administrative costs associated with our operations. Three of our product candidates are 
in early phase clinical trials being conducted by us. We have multiple other product candidates in preclinical development, as well as early-stage research programs. Our 
product candidates will require substantial additional development time and resources before we will be able to apply for or receive regulatory approvals and, if 
approved, begin generating revenue from product sales. Furthermore, we expect to continue to incur additional costs associated with operating as a public company. We 
also do not yet have a sales organization or commercial infrastructure and, accordingly, we will incur significant expenses to develop a sales organization or commercial 
infrastructure in advance of regulatory approval and generating any commercial product sales. We expect to continue to incur losses for the foreseeable future, and we 
anticipate these losses will increase as we continue to develop IDE397, darovasertib, IDE161, our other product candidates and any future product candidates, conduct 
clinical trials and pursue research and development activities. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent 
periods. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our stockholders’ deficit and working capital. 

Our operating results may fluctuate significantly, which will make our future results difficult to predict and could cause our results to fall below expectations. 

Our quarterly and annual operating results may fluctuate significantly, which will make it difficult for us to predict our future results. These fluctuations may occur due 
to a variety of factors, many of which are outside of our control and may be difficult to predict, including: 

•

•

•

•

the timing and cost of, and level of investment in, research, development and commercialization activities, which may change from time to time; 

the timing and status of enrollment for our clinical trials; 

the timing of regulatory approvals, if any, in the United States and internationally; 

the cost of manufacturing, as well as building out our supply chain, which may vary depending on the quantity of productions, and the terms of any 
agreements we enter into with third-party suppliers; 

44

 
 
 
 
 
 
 
•

•

•

•

•

•

•

timing and amount of any option exercise, milestone, royalty or other payments we may or may not receive pursuant to any current or future 
collaboration or license agreement, including under the Collaboration, Option and License Agreement with GSK;

timing and amount of any milestone, royalty or other payments due under any current or future collaboration or license agreement, including the License 
Agreement with Novartis or the Option and License Agreement with CRT and University of Manchester; 

coverage and reimbursement policies with respect to any future approved products, and potential future drugs that compete with our products; 

expenditures that we may incur to acquire, develop or commercialize additional products and technologies; 

the level of demand for any future approved products, which may vary significantly over time; 

future accounting pronouncements or changes in our accounting policies; and 

the timing and success or failure of preclinical studies and clinical trials for our product candidates or competing product candidates, or any other change 
in the competitive landscape of our industry, including consolidation among our competitors or collaboration partners. 

The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our 
operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance. 

This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue 
or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market 
are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we 
have met any previously publicly stated revenue or earnings guidance we may provide. 

We will require substantial additional financing to achieve our goals, and failure to obtain additional capital when needed on acceptable terms, or at all, could 
force us to delay, limit, reduce or terminate our product development programs, commercialization efforts or other operations. 

Since our inception, we have invested a significant portion of our efforts and financial resources in research and development activities for our precision medicine target 
and biomarker discovery platform and our initial preclinical and clinical product candidates. Preclinical studies and clinical trials and additional research and 
development activities will require substantial funds to complete. As of December 31, 2023, we had cash, cash equivalents and marketable securities of $632.6 million. 

We believe that we will continue to expend substantial resources for the foreseeable future in connection with the research and development of our precision medicine 
target and biomarker discovery platform, clinical and preclinical product candidates, and any other future product candidates we may choose to pursue, as well as other 
corporate uses. Specifically, in the near term, we expect to incur substantial expenses as we advance our synthetic lethality product candidates through preclinical 
studies, advance darovasertib, IDE397 and IDE161 through clinical development, seek regulatory approval, prepare for and, if approved, proceed to commercialization, 
and continue our research and development efforts. These expenses will include our cost sharing obligations with GSK for research and development for our WRN 
program and our cost sharing obligations with Amgen for the Phase 1/2 clinical trial to evaluate IDE397 in combination with AMG 193. These expenditures will 
include costs associated with conducting preclinical studies and clinical trials, obtaining regulatory approvals, and manufacturing and supply, as well as marketing and 
selling any products approved for sale. In addition, other unanticipated costs may arise. Because the outcome of any preclinical study or clinical trial is highly uncertain, 
we cannot reasonably estimate the actual amounts necessary to successfully develop and commercialize our product candidates or any future product candidates.

We believe that our existing cash, cash equivalents and marketable securities will allow us to fund our planned operations for at least 12 months from the date of the 
issuance of the financial statements included in this Form 10-K. However, our operating plans and other demands on our capital resources may change as a result of 
many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings or other 
sources, such as strategic collaborations. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe 
we have sufficient funds for our current or future operating plans. Such financing may result in dilution to stockholders, imposition of burdensome debt covenants and 
repayment obligations, or other restrictions that may adversely affect our business. If we raise additional funds through licensing or collaboration 

45

 
 
 
 
 
 
 
arrangements with third parties, we may have to relinquish valuable rights to our product candidates, or grant licenses on terms that are not favorable to us. Attempting 
to secure additional financing may also divert our management from our day-to-day activities, which may adversely affect our ability to develop our product candidates. 
In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. 

Our future capital requirements will depend on many factors, including: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the scope, progress, results and costs of developing our product candidates or any other future product candidates, and conducting preclinical studies and 
clinical trials, including our ongoing clinical trials for IDE397, darovasertib and IDE161; 

the scope, progress, results and costs related to the research and development of our precision medicine target and biomarker discovery platform, 
including costs related to the development of our proprietary libraries and database of tumor genetic information and specific cancer-target dependency 
networks; 

the timing of, and the costs involved in, obtaining regulatory approvals for our product candidates or any future product candidates, or any applicable 
diagnostics; 

the number and characteristics of any additional product candidates we develop or acquire; 

the cost of coordinating and/or collaborating with certain diagnostic companies for manufacturing and supply of companion diagnostics for biomarkers 
associated with our product candidates and any future product candidates; 

our ability to maintain existing, and establish new, strategic collaborations, licensing or other arrangements and the financial terms of any such 
agreements, including the Collaboration, Option and License Agreement with GSK, the License Agreement with Novartis and the Option and License 
Agreement with Cancer Research Technology Ltd., or CRT, and University of Manchester; 

the timing and amount of any option exercise, milestone, royalty or other payments we may or may not receive pursuant to any current or future 
collaboration or license agreement, including under the Collaboration, Option and License Agreement with GSK; 

the timing and amount of any milestone, royalty or other payments we are required to make pursuant to any current or future collaboration or license 
agreement, including under the License Agreement with Novartis or the Option and License Agreement with CRT and University of Manchester; 

potential delays in our ongoing clinical programs as a result of any public health outbreaks, epidemics or pandemics (such as the COVID-19 pandemic);

the cost of manufacturing our product candidates and any future products we successfully commercialize; 

the cost of commercialization activities, including the cost of building a sales force in anticipation of product commercialization and distribution costs; 

any product liability or other lawsuits related to our product candidates or future approved products;

the expenses needed to attract, hire and retain skilled personnel; 

the costs associated with being a public company; 

the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing our intellectual property portfolio; and 

the timing, receipt and amount of sales of any future approved products, if any. 

Our ability to raise additional funds will depend on financial, economic and other factors, including the ongoing effects of the COVID-19 pandemic, the Ukraine-Russia 
conflict, the Israel-Hamas conflict, and closure of or liquidity issues at financial institutions (including, for example, Silicon Valley Bank), many of which are beyond 
our control. Additional funds may not be available when we need them, on terms that are acceptable to us, or at all. Furthermore, we maintain the majority of our cash 
and cash equivalents in accounts with major U.S. and multi-national financial institutions, and our deposits at certain of these institutions exceed insured limits. Market 
conditions can impact the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there 
can be no assurance that we would be able to access uninsured funds in a timely manner or at all. If adequate funds are not available to us on a timely basis, we may be 
required to: 

46

 
 
 
•

•

delay, limit, reduce or terminate preclinical studies, clinical trials or other research and development activities or eliminate one or more of our 
development programs altogether; or 

delay, limit, reduce or terminate our efforts to establish manufacturing and sales and marketing capabilities or other activities that may be necessary to 
commercialize darovasertib, if approved, IDE397, if approved, IDE161, if approved, or any other future approved products, or reduce our flexibility in 
developing or maintaining our sales and marketing strategy. 

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies. 

To date, we have primarily financed our operations through the sale of equity securities and payments received under our collaboration agreements. We will be required 
to seek additional funding in the future and currently intend to do so through collaborations, public or private equity offerings or debt financings, credit or loan facilities 
or a combination of one or more of these funding sources. If we raise additional funds by issuing equity securities, our stockholders may suffer dilution and the terms of 
any financing may adversely affect the rights of our stockholders. In addition, as a condition to providing additional funds to us, future investors may demand, and may 
be granted, rights superior to those of existing stockholders. Debt financing, if available, is likely to involve restrictive covenants limiting our flexibility in conducting 
future business activities, and, in the event of insolvency, debt holders would be repaid before holders of our equity securities received any distribution of our corporate 
assets. We also could be required to seek funds through arrangements with collaborators or others that may require us to relinquish rights or jointly own some aspects of 
our technologies or product candidates that we would otherwise pursue on our own. 

Risks Related to Our Business 

We are early in our development efforts. Our business is dependent on the successful development of our product candidates, future product candidates, and 
companion diagnostics for biomarkers associated with our product candidates and future product candidates.

Our current product candidates are in early stages of development and we are further developing our precision medicine target and biomarker discovery platform. We 
have no products approved for sale and our three most advanced product candidates, IDE397, darovasertib and IDE161, are in the early stages of clinical development 
and will require additional clinical development, regulatory review and approval in each jurisdiction in which we intend to market them, access to sufficient commercial 
manufacturing capacity, and significant sales and marketing efforts before we can generate any revenue from product sales. Our other product candidates have not been 
tested in clinical trials. The success of our business, including our ability to finance our company and generate revenue in the future, will primarily depend on the 
successful development, regulatory approval and commercialization of our product candidates, which may never occur. In the future, we may also become dependent on 
other product candidates that we may develop or acquire; however, given our early stage of development, it may be many years, if at all, before we have demonstrated 
the safety and efficacy of a product candidate sufficient to support approval for commercialization. 

We have not previously submitted a new drug application, or NDA, to the FDA or similar approval filings to a comparable foreign regulatory authority, for any product 
candidate. An NDA or other relevant regulatory filing must include extensive preclinical and clinical data and supporting information to establish that the product 
candidate is safe and effective for each desired indication. The NDA or other relevant regulatory filing must also include significant information regarding the 
chemistry, manufacturing and controls for the product. We cannot be certain that our current or future product candidates will be successful in clinical trials or receive 
regulatory approval. Further, even if they are successful in clinical trials, our product candidates or any future product candidates may not receive regulatory approval. 
If we do not receive regulatory approvals for current or future product candidates, we may not be able to continue our operations. Even if we successfully obtain 
regulatory approval to market a product candidate, our revenue will depend, in part, upon the size of the markets in the territories for which we gain regulatory approval 
and have commercial rights, as well as the availability of competitive products, whether there is sufficient third-party reimbursement and adoption by physicians. 

We plan to seek regulatory approval to commercialize our product candidates both in the United States and in select foreign countries. While the scope of regulatory 
approval generally is similar in other countries, in order to obtain separate regulatory approval in other countries we must comply with numerous and varying regulatory 
requirements of such countries regarding safety and efficacy. Other countries also have their own regulations governing, among other things, clinical trials and 
commercial sales, as well as pricing and distribution of drugs, and we may be required to expend significant resources to obtain regulatory approval and to comply with 
ongoing regulations in these jurisdictions. 

47

 
 
 
 
 
 
 
 
The clinical and commercial success of our current and any future product candidates will depend on a number of factors, including the following: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

our ability to raise any additional required capital on acceptable terms, or at all; 

our ability to develop and successfully utilize our precision medicine target and biomarker discovery platform; 

timely and successful completion of our preclinical studies and clinical trials, which may be significantly slower or cost more than we currently 
anticipate and will depend substantially upon the performance of third-party contractors; 

acceptance of INDs by the FDA, or similar regulatory filing by a comparable foreign regulatory authority for the conduct of clinical trials of our product 
candidates and our proposed design of future clinical trials; 

whether we are required by the FDA or a comparable foreign regulatory agency to conduct additional clinical trials or other studies beyond those 
planned to support approval of our product candidates; 

our ability to timely execute our ongoing clinical trials and enroll a sufficient number of patients on a timely basis to evaluate our product candidates in 
clinical development;

acceptance of our proposed indications and primary endpoint assessments of our product candidates by the FDA and comparable foreign regulatory 
authorities; 

the availability or successful development of companion diagnostics for biomarkers associated with our product candidates or any other future product 
candidates; 

our ability to make arrangements with third-party manufacturers for, or establish, commercial manufacturing capabilities, and to consistently 
manufacture our product candidates on a timely basis; 

our ability, and the ability of any third parties with whom we contract, to remain in good standing with regulatory agencies and develop, validate and 
maintain commercially viable manufacturing processes that are compliant with current good manufacturing practices, or cGMPs, or similar foreign 
requirements; 

our ability to demonstrate to the satisfaction of the FDA and comparable foreign regulatory authorities the safety, efficacy and acceptable risk-benefit 
profile of our product candidates; 

the prevalence, duration and severity of potential side effects or other safety issues experienced with our product candidates, either as monotherapy or in 
combination with other drugs, or future approved products, if any; 

the timely receipt of necessary marketing approvals from the FDA and comparable foreign regulatory authorities; 

achieving and maintaining, and, where applicable, ensuring that our third-party contractors achieve and maintain, compliance with our contractual 
obligations and with all regulatory requirements applicable to our current product candidates or any future product candidates or approved products, if 
any; 

the willingness of physicians, operators of hospitals and clinics and patients to use or adopt any approved products, as well as the willingness of 
physicians and other health-care providers to incorporate molecular diagnostics or genetic sequencing into their clinical practice; 

our ability to successfully develop a commercial strategy and thereafter commercialize any approved products in the United States and internationally, 
whether alone or in collaboration with others; 

the availability and level of coverage and adequate reimbursement from managed care plans, private insurers, government payors, such as Medicare and 
Medicaid, and other third-party payors for any of our product candidates that may be approved; 

the convenience of our treatment or dosing regimen; 

our ability to compete with other approved therapies, if any; 

acceptance by physicians, payors and patients of the benefits, safety and efficacy of our product candidates or any future product candidates, if approved, 
including relative to alternative and competing treatments; 

patient demand for any approved products; 

our ability to establish and enforce intellectual property rights in and to our product candidates; and 

48

 
 
•

our ability to avoid third-party patent interference, opposition, derivation, intellectual property challenges, intellectual property infringement claims or 
similar proceedings with respect to our intellectual property rights. 

These factors, many of which are beyond our control, could cause us to experience significant delays or an inability to obtain regulatory approvals or commercialize our 
current or future product candidates. Even if regulatory approvals are obtained, we may never be able to successfully commercialize any products. Accordingly, we 
cannot provide assurances that we will be able to generate sufficient revenue through the sale of products to continue our business or achieve profitability. 

In connection with the Collaboration, Option and License Agreement with GSK, if GSK terminates any development program under its collaborations with us, 
whether as a result of our inability to meet milestones or otherwise, any potential revenue from those collaborations will be significantly reduced or non-existent, 
and our results of operations and financial condition will be materially and adversely affected.

We have invested a significant portion of our time and financial resources in the development of multiple product candidates that are included in our strategic 
partnership and collaboration with GSK, under the Collaboration, Option and License Agreement entered into on June 15, 2020, or the GSK Collaboration Agreement. 
The programs currently included in the GSK Collaboration Agreement are the Pol Theta and Werner Helicase (WRN) programs. 

Under the GSK Collaboration Agreement, we will be eligible to receive from GSK future development and regulatory milestones of up to $475 million for the Pol 
Theta and $482.0 million for the WRN product, and commercial milestones of up to $475 million, with respect to the Pol Theta and WRN product. Additionally, we are 
entitled to receive 50% of U.S. net profits and tiered royalties on global non-U.S. net sales of WRN products by GSK, its affiliates and their sublicensees ranging from 
high single digit to sub-teen double digit percentages, subject to certain customary reductions. We are entitled to receive tiered royalties on global net sales of Pol Theta 
products by GSK, its affiliates and their sublicensees ranging from high single digit to sub-teen double digit percentages, subject to certain customary reductions. We 
have a right to opt-out of the 50% U.S. net profit share and corresponding development cost share for the WRN program, and would be eligible to receive tiered 
royalties on U.S. net sales of WRN products by GSK, its affiliates and their sublicensees at the same royalty rates as for global non-U.S. net sales thereafter, with 
potential positive economic adjustments based on the stage of the WRN program, as applicable, at the time of opt-out. There is no guarantee that we will be able to 
successfully continue to advance the Pol Theta and WRN programs and receive regulatory filing milestone payments related to any Pol Theta or WRN product. GSK 
may terminate the entire GSK Collaboration Agreement or any collaboration program on a target-by-target basis for any or no reason upon written notice to us after 
expiration of a defined notice period. The GSK Collaboration Agreement or any program under the GSK Collaboration Agreement may also be terminated by either 
party for the other party’s insolvency or certain uncured breaches. We may terminate the GSK Collaboration Agreement if GSK or any of its sublicensees or affiliates 
challenge certain of our patents. Depending on the timing of any such termination we may not be entitled to receive the option exercise fees, or potential milestone 
payments, as these payments terminate with termination of the GSK Collaboration Agreement.

If GSK terminates its rights and obligations with respect to a program or the entire GSK Collaboration Agreement, then depending on the timing of such event:

•

•

•

•

the development of our product candidates subject to the GSK Collaboration Agreement may be terminated or significantly delayed;

our cash expenditures could increase significantly if it is necessary for us to hire additional employees and allocate scarce resources to the development 
and commercialization of product candidates that were previously funded by GSK;

we would bear all of the risks and costs related to the further development and commercialization of product candidates that were previously the subject 
of the GSK Collaboration Agreement, including the reimbursement of third parties; and

in order to fund further development and commercialization, we may need to seek out and establish alternative collaboration arrangements with third-
party collaboration partners; this may not be possible, or we may not be able to do so on terms which are acceptable to us, in which case it may be 
necessary for us to limit the size or scope of one or more of our programs or increase our expenditures and seek additional funding by other means.

Any of these events would have a material adverse effect on our results of operations and financial condition.

49

 
 
 
 
 
 
 
 
As an organization, we have never completed a clinical trial, and may be unable to do so for any of our product candidates. 

We will need to successfully initiate and complete our own Phase 1 clinical trials and later-stage and pivotal clinical trials in order to obtain FDA or a comparable 
foreign regulatory body’s approval to market our product candidates. Carrying out clinical trials and the submission of regulatory filings is a complicated process. As an 
organization, we have not yet completed any clinical trials for any of our product candidates. We have limited experience in preparing, submitting and prosecuting 
regulatory filings, and have not previously submitted any NDA or other comparable foreign regulatory submission for any product candidate. In addition, we have had 
limited interactions with the FDA and cannot be certain how many additional clinical trials of darovasertib, IDE397 or IDE161 or how many clinical trials of any of our 
other product candidates will be required or whether the FDA will agree with the design or implementation of our clinical trials. We are required to comply with certain 
regulatory requirements, and the FDA may identify specific clinical or other development-related requirements that we must satisfy, as a condition to initiating or 
continuing our clinical trials; if we fail to meet such a requirement, the FDA may issue a clinical hold or designate other conditions on our clinical trials. Consequently, 
we may be unable to successfully and efficiently execute and complete necessary clinical trials in a way that leads to regulatory submission of a marketing application 
for, and approval of, darovasertib, IDE397, IDE161, or any of our other product candidates. We may require more time and incur greater costs than our competitors and 
may not succeed in obtaining regulatory approvals of product candidates that we develop. Failure to commence or complete, or delays in, our planned clinical trials, 
could prevent us from or delay us in commercializing darovasertib, IDE397, IDE161, or any other product candidate. 

The successful development of targeted therapeutics, including therapeutics involving direct targeting of an oncogenic pathway and synthetic lethality therapeutics, 
including our portfolio of synthetic lethality small molecule inhibitors, as well as any related diagnostics, is highly uncertain. 

Successful development of targeted therapeutics, including therapeutics involving direct targeting oncogenic pathways and synthetic lethality therapeutics, such as our 
portfolio of synthetic lethality small molecule inhibitors, as well as any related diagnostics, is highly uncertain and is dependent on numerous factors, many of which 
are beyond our control. Our precision medicine target and biomarker discovery platform is based on new technologies and methods relating to drug target and 
biomarker identification, screening and validation, including Dual CRISPR genetic screening and bioinformatics and we have not, to date, sought regulatory approval 
for any therapeutics developed through our precision medicine target and biomarker discovery platform. As such, it is difficult to accurately predict the developmental 
challenges we or our collaboration partners may incur for our current and future product candidates as we proceed through product discovery, identification, preclinical 
studies and clinical trials. 

Our precision medicine target and biomarker discovery platform is novel and may not be effective at identifying targets and/or biomarkers for product candidates. We 
therefore cannot provide any assurance that we will be able to successfully identify additional product candidates or biomarkers, advance any of these additional 
product candidates or diagnostics for their associated biomarkers through the development process.

Additionally, particular patient genetic alterations, such as mutations, deletions or fusions may not be functionally active genetic drivers of the disease. Further, whether 
a genetic alteration is functionally active may be difficult to ascertain from preclinical cancer models, may be tissue-type dependent and may vary from patient to 
patient within a specific indication. If that was the case, we would need to functionally validate such genetic alterations, for example, using in vitro and in vivo models, 
potentially across more than one tumor-tissue type and across multiple cell lines. If some of the genetic alterations are not functionally validated, this would reduce the 
size of our addressable patient population. Even if genetic alterations are preclinically validated, the relevance of these alterations may not translate into a human 
clinical setting, which could adversely impact our clinical trial results and our commercial opportunities. 

Targeted therapeutics that appear promising in the early phases of development may fail to reach the market for several reasons, including:

•

•

research or preclinical studies may show our targeted small molecule inhibitors or antagonists to be less effective than desired or to have harmful or 
problematic side effects or toxicities; 

failure to accurately identify, validate or develop clinically relevant biomarkers for our targeted therapeutic product candidates; 

50

 
 
 
 
 
 
 
•

•

•

•

clinical trial results may show our targeted therapeutic small molecule inhibitors to be less effective than expected based on preclinical studies (e.g., a 
clinical trial could fail to meet its primary endpoint(s)) or to have unacceptable side effects or toxicities; 

failure to receive the necessary regulatory approvals or a delay in receiving such approvals. Among other things, such delays may be caused by slow 
enrollment in clinical trials, patients dropping out of trials, length of time to achieve trial endpoints, additional time requirements for data analysis, IND 
preparation, discussions with the FDA or similar foreign regulatory authorities, an FDA or similar foreign regulatory authority request for additional 
preclinical or clinical data, or unexpected safety or manufacturing issues; 

manufacturing costs, formulation issues, pricing or reimbursement issues, or other factors that may make our targeted therapeutic small molecule 
inhibitors uneconomical; and 

proprietary rights of others and their competing products and technologies that may prevent our targeted therapeutic small molecule inhibitors, or the 
diagnostics for biomarkers associated with such small molecule inhibitors, from being commercialized.

As a result of these factors, it is more difficult for us to predict the time and cost of product candidate development, and we cannot predict whether the application of 
our precision medicine target and biomarker discovery platform will result in the identification, development, and regulatory approval of any products. The length of 
time necessary to complete clinical trials and to submit an application for marketing approval for a decision by a regulatory authority may be difficult to predict for 
targeted therapeutic small molecule inhibitors, in large part because of the limited regulatory history associated with them. The clinical trial requirements of the FDA 
and other comparable foreign regulatory authorities and the criteria these regulators use to determine the safety and efficacy of a product candidate vary substantially 
according to the type, complexity, novelty and intended use and market of the product candidate. Except for certain PARP inhibitors, no products based on synthetic 
lethality have been approved to date by regulators. As a result, the regulatory approval process for product candidates such as ours is uncertain and may be more 
expensive and take longer than the approval process for product candidates based on other, better known or more extensively studied technologies. It is difficult to 
determine how long it will take or how much it will cost to obtain regulatory approvals for our product candidates in either the United States or other comparable 
regions of the world or how long it will take to commercialize our product candidates. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory 
approval necessary to bring a potential product candidate to market would adversely affect our business, financial condition, results of operations and prospects. 

Even if we are successful in obtaining regulatory approval, commercial success of any approved products will also depend in large part on the availability of insurance 
coverage and adequate reimbursement from third-party payors, including government payors, such as the Medicare and Medicaid programs, and managed care 
organizations, which may be affected by existing and future healthcare reform measures designed to reduce the cost of healthcare. Third-party payors could require us 
to conduct additional studies, including post-marketing studies related to the cost-effectiveness of a product, to qualify for reimbursement, which could be costly and 
divert our resources. If government and other healthcare payors were not to provide adequate insurance coverage and reimbursement levels for one any of our products 
once approved, market acceptance and commercial success would be limited.

In addition, if any of our products is approved for marketing, we will be subject to significant regulatory obligations regarding the submission of safety and other post-
marketing information and reports and registration, and will need to continue to comply (or ensure that our third-party providers comply) with cGMPs, or similar 
applicable foreign requirements and GCPs for any clinical trials that we conduct post-approval. In addition, there is always the risk that we or a regulatory authority 
might identify previously unknown problems with a product post-approval, such as adverse events, or AEs, of unanticipated severity or frequency. Compliance with 
these requirements is costly and any failure to comply or other post-approval issues with our product candidates could have a material adverse effect on our business, 
financial condition, results of operations and prospects.

Preclinical and clinical drug development is a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience delays in 
completing, or ultimately be unable to complete, the development and commercialization of any product candidates, which could result in increased costs to us, 
delay or limit our ability to generate revenue and adversely affect our business, financial condition, results of operations and prospects. Furthermore, results of 
earlier studies and trials may not be predictive of future trial results. 

Before we can initiate clinical trials for our product candidates, we must submit the results of preclinical studies to the FDA or a comparable foreign regulatory 
authority along with other information, including information about product candidate 

51

 
 
 
 
 
 
chemistry, manufacturing and controls, diagnostics for biomarkers for our product candidates and our proposed clinical trial protocol, as part of an IND application or 
similar regulatory filing. 

Before obtaining marketing approval from regulatory authorities for the sale of any products, we, or our collaboration partners must conduct extensive clinical trials to 
demonstrate the safety and efficacy of the product candidates in humans. Clinical trials are expensive and can take many years to complete, and their outcome is 
inherently uncertain. Failure can occur at any time during the clinical trial process. In addition, we may rely in part on preclinical, clinical and quality data generated by 
contract research organizations, or CROs, and other third parties for regulatory submissions for our product candidates. While we have or will have agreements 
governing these third parties’ services, we have limited influence over their actual performance. Further, pursuant to our license agreement with Novartis, we have a 
right of reference to certain data from Novartis’ Phase 1 clinical trial data for our regulatory filings for darovasertib. 

If these third parties, including Novartis, fail to make data available to us, or, if applicable, make regulatory submissions in a timely manner, in each case pursuant to 
our agreements with them, our development programs may be significantly delayed and we may need to conduct additional studies or trials or collect additional data 
independently. In either case, our development costs would increase. 

Our clinical trial collaboration and supply agreements with Pfizer, Amgen and Gilead for the supply of crizotinib, AMG 193 and Trodelvy, respectively, support our 
plans to evaluate the safety and efficacy of darovasertib in combination with crizotinib, IDE397 in combination with AMG 193, and IDE397 in combination with 
Trodelvy. If any of these strategic collaborators delay or fail to supply their compound in support of these combination trials, fail to sponsor or appropriately conduct the 
combination trial (in the case of Amgen), or we fail to reach an agreement with any of these strategic collaborators for the continued supply of their compound beyond 
the terms of the current supply agreements, the development programs as pertaining to these combinations may be significantly delayed, and our development costs 
may increase. In each case, this may require us to establish additional supply agreements and rely upon third parties for supply of such combination agents, or if such 
combination agents are commercially available, in the absence of a supply agreement, we may incur the cost of purchasing such combination agents and may be at risk 
of having insufficient supply. We may initiate clinical trials in which our product candidates, including darovasertib, IDE397 or IDE161, are combined with one or more 
other pharmaceutical agents that have not yet been approved by the FDA or comparable foreign regulatory authorities; in such situations, we may be relying on third 
parties for obtaining appropriate regulatory approvals and we may have no or limited influence over whether or not such regulatory approvals are achieved for such 
combination agents. 

We and our strategic collaborators also may experience numerous unforeseen events during, or as a result of, any preclinical studies or clinical trials that could delay or 
prevent us or our strategic collaborators from successfully developing our product candidates, including: 

•

•

•

•

•

•

•

•

•

•

•

we may be unable to generate sufficient preclinical, toxicology, or other in vivo or in vitro data to support the initiation of clinical trials; 

the FDA or a comparable foreign regulatory authority disagreeing as to the design or implementation of our clinical trials; 

delays in obtaining regulatory authorization to commence a clinical trial; 

reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and 
may vary significantly among different CROs and clinical trial sites; 

obtaining IRB or ethics committee approval or positive opinion at each clinical trial site; 

recruiting an adequate number of suitable patients to participate in a clinical trial, particularly if any public health outbreak, epidemic or pandemic leads 
to clinical site closures; 

having patients complete a clinical trial or return for post-treatment follow-up; 

clinical sites deviating from clinical trial protocol or dropping out of a clinical trial; 

addressing subject safety concerns that arise during the course of a clinical trial; 

adding a sufficient number of clinical trial sites; 

obtaining sufficient quantities of product candidate for use in preclinical studies or clinical trials from third-party suppliers; or 

52

 
 
 
 
 
•

accessing third-party products or product candidates for use in combination with our product candidates in preclinical studies or clinical trials, including 
third-party product candidates that have not yet been approved by the FDA or comparable foreign regulatory authorities. 

We and our strategic collaborators may experience numerous adverse or unforeseen events during, or as a result of, preclinical studies and clinical trials that could delay 
or prevent our ability to receive marketing approval or commercialize our product candidates, including:

•

•

•

•

•

•

•

•

•

we may receive feedback from regulatory authorities that requires us to modify the design of our clinical trials; 

clinical trials of our product candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct 
additional clinical trials or abandon our development programs; 

the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may be 
slower than we anticipate or participants may drop out of these clinical trials at a higher rate than we anticipate; 

we or our third-party contractors may fail to comply with regulatory requirements, fail to maintain adequate quality controls, or be unable to produce 
sufficient product supply to conduct and complete preclinical studies or clinical trials of our product candidates in a timely manner, or at all; 

we or our investigators might have to suspend or terminate clinical trials of our product candidates for various reasons, including non-compliance with 
regulatory requirements, a finding that our product candidates have undesirable side effects or other unexpected characteristics, or a finding that the 
participants are being exposed to unacceptable health risks; 

the cost of clinical trials of our product candidates may be greater than we anticipate; 

the quality of our product candidates or other materials necessary to conduct preclinical studies or clinical trials of our product candidates may be 
insufficient or inadequate;

regulators may revise the requirements for approving our product candidates, or such requirements may not be as we anticipate; and 

collaborators may conduct clinical trials in ways they view as advantageous to them but that are suboptimal for us. 

If we or our strategic collaborators are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently 
contemplate, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not positive or are 
only moderately positive or if there are safety concerns, we may:

•

•

•

•

•

•

•

incur unplanned costs;

be delayed in obtaining marketing approval for our product candidates or not obtain marketing approval at all; 

obtain marketing approval in some countries and not in others; 

obtain marketing approval for indications or patient populations that are not as broad as intended or desired; 

obtain marketing approval with labeling that includes significant use or distribution restrictions or safety warnings, including boxed warnings; 

be subject to additional post-marketing testing requirements, which could be expensive and time-consuming; or 

have the treatment removed from the market after obtaining marketing approval. 

We and our strategic collaborators could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such trials are 
being conducted, by the Data Safety Monitoring Board, or DSMB, for such trial or by the FDA or another comparable foreign regulatory authority. Such authorities 
may suspend or terminate a clinical trial due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our 
clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, 
unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative 
actions or lack of adequate funding to continue the clinical trial. In addition, changes in regulatory requirements and policies may occur, and we may need to amend 
clinical trial 

53

 
 
 
 
protocols to comply with these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs or other foreign regulatory authorities or ethics 
committees for reexamination, which may impact the costs, timing or successful completion of a clinical trial. For example, in recent years the FDA has issued draft 
guidance and launched programs aiming to reform and modernize the dose optimization procedures used by clinical trial sponsors during the development of oncology 
drugs. Although these efforts have not yet resulted in any formal changes to the FDA’s regulations or policies, changes in the FDA’s thinking with respect to dose 
selection and optimization could require us to change the design of our planned or ongoing clinical trials or otherwise conduct additional preclinical, clinical or 
manufacturing studies beyond those we currently anticipate, which could increase our costs and/or delay the development of our product candidates.

As another example, the regulatory landscape related to clinical trials in the EU recently evolved. The EU Clinical Trials Regulation, or CTR, which was adopted in 
April 2014 and repeals the EU Clinical Trials Directive, became applicable on January 31, 2022. While the EU Clinical Trials Directive required a separate clinical trial 
application, or CTA, to be submitted in each member state in which the clinical trial takes place, to both the competent national health authority and an independent 
ethics committee, the CTR introduces a centralized process and only requires the submission of a single application for multi-center trials. The CTR allows sponsors to 
make a single submission to both the competent authority and an ethics committee in each member state, leading to a single decision per member state. The assessment 
procedure of the CTA has been harmonized as well, including a joint assessment by all member states concerned, and a separate assessment by each member state with 
respect to specific requirements related to its own territory, including ethics rules. Each member state’s decision is communicated to the sponsor via the centralized EU 
portal. Once the CTA is approved, clinical study development may proceed. The CTR foresees a three-year transition period. The extent to which ongoing and new 
clinical trials will be governed by the CTR varies. Clinical trials for which an application was submitted (i) prior to January 31, 2022 under the EU Clinical Trials 
Directive, or (ii) between January 31, 2022 and January 31, 2023 and for which the sponsor has opted for the application of the EU Clinical Trials Directive remain 
governed by said Directive until January 31, 2025. After this date, all clinical trials (including those which are ongoing) will become subject to the provisions of the 
CTR. Compliance with the CTR requirements by us and our third-party service providers, such as CROs, may impact our developments plans.

Further, conducting clinical trials in foreign countries, as we may do for certain of our product candidates, presents additional risks that may delay completion of our 
clinical trials. These risks include the possibility that we could be required to conduct additional preclinical studies before initiating any clinical trials, the failure of 
enrolled patients in foreign countries to adhere to clinical protocol as a result of differences in healthcare services or cultural customs, managing additional 
administrative burdens associated with comparable foreign regulatory schemes, as well as political and economic risks relevant to such foreign countries. 

Principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and may receive cash or equity compensation in 
connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or a regulatory authority concludes 
that the financial relationship may have affected the interpretation of the clinical trial, the integrity of the data generated at the applicable clinical trial site may be 
questioned and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection of the marketing application we submit. Any such 
delay or rejection could prevent or delay us from commercializing our current or future product candidates.

If any of our preclinical studies or clinical trials of our product candidates are delayed or terminated, the commercial prospects of our product candidates may be 
harmed, and our ability to ultimately generate revenues from any of these product candidates will be delayed or not realized at all. In addition, any delays in completing 
our clinical trials may increase our costs, slow down our product candidate development and regulatory approval process and jeopardize our ability to commence 
product sales and generate revenues. Any of these occurrences may significantly harm our business, financial condition, results of operations and prospects. In addition, 
many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of 
our product candidates. If our product candidates and any future product candidates prove to be ineffective, unsafe or commercially unviable, our entire platform and 
approach would have little, if any, value, which would have a material adverse effect on our business, financial condition, results of operations and prospects.

Furthermore, the results of preclinical studies and clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Product 
candidates in later stages of clinical trials may fail to show the desired safety and efficacy despite having progressed through preclinical studies and initial clinical trials. 
Furthermore, for some of our programs, in the future we intend to conduct basket trials, which will be designed to include multiple clinically defined populations under 
one investigational protocol, although each population is enrolled and analyzed separately. A basket trial design could potentially decrease the time to study new 
populations by decreasing administrative burden, however, these trials may not provide opportunities for accelerated regulatory pathways, and do not overcome 
limitations to extrapolating data from the experience 

54

 
 
 
 
 
 
in one disease to other diseases, because safety and efficacy results in each indication are analyzed separately. Accordingly, clinical success in a basket trial, or any trial 
in one indication, may not predict success in another indication. In contrast, in the event of an adverse safety issue, clinical hold, or other adverse finding in one or more 
indications being tested, such event could adversely affect our trials in the other indications and may delay or prevent completion of the clinical trials. A number of 
companies in the pharmaceutical, biopharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials for similar indications 
that we are pursuing due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier studies, and we cannot be certain that we will not 
face similar setbacks. Even if our clinical trials are completed, the results may not be sufficient to obtain regulatory approval of any products. 

Synthetic lethality represents an emerging class of precision medicine targets, and negative perceptions of the efficacy, safety or tolerability of this class of targets, 
including any that we develop, could adversely affect our ability to conduct our business, advance our product candidates or obtain regulatory approvals. 

Aside from PARP inhibitors, such as Lynparza, Rubraca, Zejula and Talzenna, no synthetic lethality small molecule inhibitor therapeutics have been approved to date 
by the FDA or other comparable regulators. AEs in future clinical trials of our product candidates or in clinical trials of others developing similar products and the 
resulting publicity, as well as any other AEs in the field of synthetic lethality, or other products that are perceived to be similar to synthetic lethality, such as those 
related to gene therapy or gene editing, could result in a decrease in the perceived benefit of one or more of our programs, increased regulatory scrutiny, decreased 
confidence by patients and CROs in our product candidates, and less demand for any product that we may develop. Our substantial pipeline of synthetic lethality small 
molecule inhibitor product candidates could result in a greater quantity of reportable AEs or other reportable negative clinical outcomes, manufacturing reportable 
events or material clinical events that could lead to clinical delays or holds by the FDA or applicable regulatory authority or other clinical delays, any of which could 
negatively impact the perception of one or more of our synthetic lethality programs, as well as our business as a whole. In addition, responses by U.S. federal, state or 
foreign governments to negative public perception may result in new legislation or regulations that could limit our ability to develop any product candidates or 
commercialize any approved products, obtain or maintain regulatory approval, or otherwise achieve profitability. More restrictive statutory regimes, government 
regulations, or negative public opinion would have an adverse effect on our business, financial condition, results of operations, and prospects, and may delay or impair 
the development of our product candidates and commercialization of any approved products or demand for any products we may develop.

Tissue-type agnostic basket trials are an emerging clinical approach that may result in delays in clinical development, additional regulatory requirements and 
delays in, or the prevention of, our ability to obtain regulatory approval or commercialize our product candidates. 

We initiated a Phase 1/2 tissue-type agnostic basket trial with darovasertib in June 2019, and may also utilize a basket trial approach in clinical trials for other product 
candidates. Basket trials allow us to evaluate the safety and efficacy of a product candidate in a variety of tumor types with a specific molecular profile. We believe that 
this clinical approach provides many benefits, however, there are limited precedents, and as a result, there a number of inherent risks. 

There is limited precedent for the FDA and foreign regulatory authorities to review and grant tissue-type agnostic approvals. Furthermore, as clinical trials increasingly 
use classification of tumors by molecular profiling, the FDA or other regulatory authority may change or issue guidance or adopt a policy that adversely affects 
requirements for basket trials. In the event that such guidance or policy has an effect on any of our protocols or trials, as the case may be, it may result in the delay of 
clinical development, or require us to conduct additional preclinical studies or clinical trials. 

Even if we obtain a tissue-type agnostic approval for one or more of our product candidates, there is limited precedent for obtaining reimbursement. Third-party payors 
may reimburse at different levels across tumor tissue types and indicates, or not at all. 

We may find it difficult to enroll patients in our clinical trials given the limited number of patients who have the diseases for which our product candidates are 
being developed. If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely 
affected. 

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our and our collaboration partners’ ability to enroll a 
sufficient number of patients who remain in the clinical trial until its conclusion. We may experience difficulties in patient enrollment in our clinical trials for a variety 
of reasons. The enrollment of patients depends on many factors, including: 

•

the patient eligibility and exclusion criteria defined in the protocol; 

55

 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

•

•

the size and nature of the patient population required for analysis of the clinical trial’s primary endpoints; 

the proximity of patients to clinical trial sites; 

the design of the clinical trial; 

the risk that enrolled patients will not complete a clinical trial; 

our ability to recruit clinical trial investigators with the appropriate competencies and experience; 

clinical trial investigators’ willingness to continue enrolling patients and patients’ willingness to complete protocol assessments during any public health 
outbreak, epidemic or pandemic;

clinicians’ and patients’ perceptions as to the safety of the product candidate; 

clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, 
including any new therapies that may be approved for the indications we are investigating as well as any drugs under development; and 

our ability to obtain and maintain patient consents. 

We will be required to identify and enroll a sufficient number of patients for each of our clinical trials. Potential patients for any planned clinical trials may not be 
adequately diagnosed or identified with the diseases which we are targeting or may not meet the entry criteria for such trials. We also may encounter difficulties in 
identifying and enrolling patients with a stage of disease appropriate for our planned clinical trials and monitoring such patients adequately during and after treatment. 
We may not be able to initiate or continue clinical trials if we are unable to locate a sufficient number of eligible patients to participate in the clinical trials required by 
the FDA or a comparable foreign regulatory authority. In addition, the process of finding and diagnosing patients may prove costly. 

In addition, our clinical trials may compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this 
competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in 
a trial being conducted by one of our competitors. As a result of any public health outbreak, competition for potential patients in our trials may be further exacerbated as 
a result of any clinical site closures. Since the number of qualified clinical investigators is already limited, we may conduct some of our clinical trials at the same 
clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials in such clinical trial site. 

Furthermore, certain conditions for which we plan to evaluate our current development candidates are rare diseases, such as metastatic uveal melanoma, with limited 
patient pools from which to draw for clinical trials. For example, one of our product candidates, darovasertib, is currently being evaluated in a Phase 1/2 basket trial that 
we initiated in June 2019 to evaluate darovasertib in solid tumors harboring GNAQ/GNA11 hotspot mutations in metastatic uveal melanoma. The timing of our clinical 
trials depends, in part, on the speed at which we can recruit patients to participate in our trials, as well as completion of required follow-up periods. The eligibility 
criteria of our clinical trials, once established, will further limit the pool of available trial participants. 

In addition, our clinical trials may be affected by any public health outbreak, epidemic or pandemic. Clinical site initiation and patient enrollment may be delayed. For 
example, as a result of the COVID-19 pandemic, several of our sites halted new enrollment for several months in 2020 before resuming enrollment. Some patients may 
not be able or willing to comply with clinical trial protocols, and data collected may be incomplete, if quarantines impede patient movement or interrupt healthcare 
services. Similarly, the ability to recruit and retain patients, and principal investigators and site staff who, as healthcare providers, may have heightened exposure to 
infectious diseases, may be delayed or disrupted, which may adversely impact our clinical trial operations. 

If patients are unwilling to participate in our clinical trials for any reason, including the existence of other approved therapies or concurrent clinical trials for similar 
patient populations, if they are unwilling to enroll in a clinical trial with a placebo-controlled design, or we otherwise have difficulty enrolling a sufficient number of 
patients, the timeline for recruiting patients, conducting studies and obtaining regulatory approval of our product candidates may be delayed. Our inability to enroll a 
sufficient number of patients for any of our future clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether. In 
addition, we expect to rely on CROs and clinical trial sites to ensure proper and timely conduct of our future clinical trials and, while we intend to enter into agreements 
governing their services, we will have limited influence over their actual performance. 

56

 
 
 
 
 
 
 
We cannot assure you that we will not experience delays in enrollment, which would result in the delay of completion of such trials beyond our expected timelines. 

Our product candidates or any future product candidates may be associated with undesirable side effects or AEs that could delay or prevent their regulatory 
approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any. 

As with most pharmaceutical products, use of our product candidates could be associated with side effects or AEs which can vary in severity from minor reactions to 
death and in frequency from infrequent to prevalent. Undesirable side effects or unacceptable toxicities caused by our product candidates could cause us or regulatory 
authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or a comparable 
foreign regulatory authority. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of these or other side effects. Furthermore, 
certain of our product candidates may be co-administered with third-party approved or experimental therapies, such as darovasertib with crizotinib in the combination 
arms of our Phase 1/2 clinical trial or IDE397 with PRMT5 inhibitors in the combination arms of our Phase 1/2 clinical trial. These combinations may have additional 
side effects. The uncertainty resulting from the use of our product candidates in combination with other therapies may make it difficult to accurately predict side effects 
in future clinical trials. 

To date, only three of our product candidates, IDE397, darovasertib, and IDE161 have been tested in clinical trials, and they have been observed to be generally well 
tolerated, with certain drug-related SAEs and AEs being reported for darovasertib, as monotherapy and in combination with crizotinib, for IDE397, and for IDE161. 

If unacceptable side effects arise in the further development of darovasertib, including in combination with crizotinib, in the further development of IDE397, including 
in combination with PRMT5 inhibitors, in the further development of IDE161, or in the development of any of our other product candidates, we, the FDA or 
comparable foreign regulatory authorities, or the IRBs at the institutions in which the clinical trials are being conducted could suspend or terminate our clinical trials or 
the FDA or a comparable foreign regulatory authority could order us to cease clinical trials or deny approval of our product candidates for any or all targeted 
indications. Treatment-related side effects could also affect patient recruitment or the ability of enrolled patients to complete any of our clinical trials or result in 
potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We expect to have to train 
medical personnel using our product candidates to understand the side effect profiles for our clinical trials and upon any commercialization of any of our product 
candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in patient injury or death. Any of these 
occurrences may harm our business, financial condition, results of operations and prospects significantly. 

In addition, even if we successfully advance our product candidates or any future product candidates into and through clinical trials, such trials will likely only include a 
limited number of patients and limited duration of exposure to our product candidates. As a result, we cannot be assured that adverse effects of our product candidates 
will not be uncovered when a significantly larger number of patients are exposed to the product candidate. Further, any clinical trials may not be sufficient to determine 
the effect and safety consequences of taking our product candidates over a multi-year period. 

If any of our product candidates receives marketing approval and we or others later identify undesirable side effects caused by such products, a number of potentially 
significant negative consequences could result, including: 

•

•

•

•

•

•

•

•

regulatory authorities may withdraw their approval of the product; 

we may be required to recall a product or change the way such product is administered to patients; 

additional restrictions may be imposed on the marketing of the particular product or the manufacturing processes for the product or any component 
thereof; 

regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication; 

we may be required to implement a Risk Evaluation and Mitigation Strategy, or REMS, or create a Medication Guide outlining the risks of such side 
effects for distribution to patients or similar risk management measures; 

we could be sued and held liable for harm caused to patients; 

the product may become less competitive; and 

our reputation may suffer. 

57

 
 
 
 
 
 
 
Any of the foregoing events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and result in the loss of 
significant revenues to us, which would adversely affect our business, financial condition, results of operations and prospects. In addition, if one or more of our product 
candidates prove to be unsafe, our entire technology platform and pipeline could be affected, which would have a material adverse effect on our business, financial 
condition, results of operations and prospects.

If we are unable to successfully develop molecular diagnostics for biomarkers that enable patient selection and/or that demonstrate drug-target interaction, or 
experience significant delays in doing so, we may not realize the full commercial potential of our product candidates. 

A key component of our strategy includes the use of molecular diagnostics to guide patient selection and/or to confirm target engagement of our product candidates. In 
some cases, a diagnostic may be commercially available, for example, on a tumor-profiling panel. If not already commercially available, we may collaborate with 
diagnostic companies for the development of biomarkers associated with our product candidates. We may have difficulty in establishing or maintaining such 
development relationships, and we will face competition from other companies in establishing these collaborations. 

There are also several risks associated with biomarker identification and validation. We, in collaboration with any diagnostic partners, may not be able to identify 
predictive biomarkers or pharmacodynamic biomarkers for one or more of our programs. We may not be able to validate potential biomarkers (e.g., certain genetic 
mutations) or their functional relevance preclinically in relevant in vitro or in vivo models. Data analytics and information from databases that we rely on for identifying 
or validating some of our biomarker-target relationships may not accurately reflect potential patient populations. Potential biomarkers, even if validated preclinically, 
may not be functionally effective or validated in human clinical trials. 

If we, in collaboration with these parties, are unable to successfully develop companion diagnostics for our product candidates, or experience delays in doing so, the 
development of our product candidates may be adversely affected. The development of companion diagnostic products requires a significant investment of working 
capital, and may not result in any future income. This could require us to raise additional funds, which could dilute our current investors or impact our ability to 
continue our operations in the future. 

There are also risks associated with diagnostics that are commercially available, including that we may not have access to reliable supply for such diagnostics.

The failure to obtain required regulatory approvals or certification for any companion diagnostic tests that we may pursue may prevent or delay approval of our 
product candidates. Moreover, the commercial success of any of our product candidates may be tied to the regulatory approval or certification, market acceptance 
and continued availability of a companion diagnostic. 

The FDA regulates in vitro companion diagnostics as medical devices that will likely be subject to and require prospective validation in clinical trials in conjunction 
with the clinical trials for our product candidates, and which will require regulatory clearance or approval prior to commercialization. We plan to collaborate with third 
parties for the development, testing and manufacturing of these companion diagnostics, the application for and receipt of any required regulatory clearances or 
approvals, and the commercial supply of these companion diagnostics. Our third-party collaborators may fail to obtain the required regulatory clearances or approvals, 
which could prevent or delay approval of our product candidates. In addition, the commercial success of any of our product candidates may be tied to and dependent 
upon the receipt of required regulatory clearances or approvals of the companion diagnostic. 

Even if a companion diagnostic is approved, we will rely on the continued ability of any third-party collaborator to make the companion diagnostic commercially 
available to us on reasonable terms in the relevant geographies. Furthermore, if commercial tumor profiling panels are not able to be updated to include additional 
tumor-associated genes, or if clinical oncologists do not incorporate molecular or genetic sequencing into their clinical practice, we may not be successful in developing 
or commercializing our existing product candidates or any future product candidates.

Further, approval, clearance or certification of companion diagnostics may be subject to further legislative or regulatory reforms notably in the EU. On May 25, 2017, 
the new In Vitro Medical Devices Regulation, or IVDR, entered into force. The IVDR repeals and replaces the EU In Vitro Diagnostic Medical Devices Directive. 
Unlike directives, which must be implemented into the national laws of the EU member states, regulations are directly applicable, i.e., without the need for adoption of 
EU member states laws implementing them, in all EU member states and are intended to eliminate current differences in the regulation of medical devices among EU 
member states. The IVDR, among other things, is intended to 

58

 
 
 
 
 
 
 
 
 
 
 
establish a uniform, transparent, predictable and sustainable regulatory framework across the EU for in vitro diagnostic medical devices and ensure a high level of 
safety and health while supporting innovation. The IVDR became applicable on May 26, 2022. However, on October 14, 2021, the European Commission had proposed 
a “progressive” roll-out of the IVDR to prevent disruption in the supply of in vitro diagnostic medical devices. Therefore, the IVDR applies since May 26, 2022 but 
there is a tiered system extending the grace period for many in vitro diagnostic medical devices (depending on their risk classification) before they have to be fully 
compliant with the Regulation.

The regulation of companion diagnostics is subject to further requirements since the IVDR became applicable as it introduced a new classification system for 
companion diagnostics which are now specifically defined as diagnostic tests that support the safe and effective use of a specific medicinal product, by identifying 
patients that are suitable or unsuitable for treatment. Companion diagnostics will have to undergo a conformity assessment by a notified body. Before it can issue an EU 
certificate, the notified body must seek a scientific opinion from the EMA on the suitability of the companion diagnostic to the medicinal product concerned if the 
medicinal product falls exclusively within the scope of the centralized procedure for the authorization of medicines, or the medicinal product is already authorized 
through the centralized procedure, or a marketing authorization application for the medicinal product has been submitted through the centralized procedure. For other 
substances, the notified body can seek the opinion from a national competent authorities or the EMA. These modifications may make it more difficult and costly for us 
to obtain regulatory clearances, approvals or certifications for our companion diagnostics or to manufacture, market or distribute our products after clearance, approval 
or certification is obtained.

Interim, “topline” and preliminary data from our clinical trials may differ materially from the final data. 

From time to time, we may publicly disclose preliminary or “topline” data from our clinical trials, which are based on a preliminary analysis of then-available data, and 
the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also 
make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully 
evaluate all data. As a result, the topline results that we report may differ from future results of the same clinical trials, or different conclusions or considerations may 
qualify such topline results, once additional data have been received and fully evaluated. Topline data also remain subject to audit and verification procedures that may 
result in the final data being materially different from the preliminary data we previously published. As a result, topline data should be viewed with caution until the 
final data is available. From time to time, we may also disclose interim data from our clinical trials. Interim data from clinical trials are subject to the risk that one or 
more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse differences between preliminary 
or interim data and final data could significantly harm our business, financial condition, results of operations and prospects. 

Others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the 
importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or 
product and the value of our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is typically a 
summary of extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our 
disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or 
otherwise regarding a particular product, product candidate or our business. If the topline data that we report differ from actual results, or if others, including regulatory 
authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our 
business, financial condition, operating results and prospects. 

We may be unable to obtain regulatory approval for our product candidates or any future product candidates. The denial or delay of such approval would prevent 
or delay commercialization of our product candidates and adversely impact our business, financial condition, operating results and prospects. 

The process of obtaining regulatory approval is expensive, often takes many years following the commencement of clinical trials and can vary substantially based upon 
the type, complexity and novelty of the product candidates involved, as well as the target indications and patient population. Approval policies or regulations may 
change, and the FDA or comparable foreign regulatory authorities have substantial discretion in the drug approval process, including the ability to delay, limit or deny 
approval of a product candidate for many reasons. Despite the time and expense invested in clinical development of product candidates, regulatory approval is never 
guaranteed. Neither we nor any collaborator or any future collaborator, is permitted to market any of our product candidates in the United States or abroad until we 
receive approval of an NDA from the FDA or similar regulatory approvals from comparable foreign regulatory authorities. 

59

 
 
 
 
 
 
 
 
Prior to obtaining approval to commercialize a product candidate in the United States, we or our collaborators must demonstrate with substantial evidence from 
adequate and well-controlled clinical trials, and to the satisfaction of the FDA, that such product candidates are safe and effective for their intended uses. Foreign 
regulatory authorities may require a similar demonstration before we can obtain approval to commercialize a product candidate abroad. Results from preclinical studies 
and clinical trials can be interpreted in different ways. Even if we believe the preclinical or clinical data for our product candidates are promising, such data may not be 
sufficient to support approval by the FDA or comparable foreign regulatory authorities. The FDA or a comparable foreign regulatory authority, as the case may be, may 
also require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or post-approval, or may object to elements of our 
clinical development program.

The FDA or a comparable foreign regulatory authority can delay, limit or deny approval of a product candidate for many reasons, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

such authorities may disagree with the design or implementation of our clinical trials; 

negative or ambiguous results from our clinical trials, or results may not meet the level of statistical significance required by the FDA or a comparable 
foreign regulatory agency for approval; 

serious and unexpected drug-related side effects may be experienced by participants in our clinical trials or by individuals using drugs similar to our 
product candidates; 

the population studied in the clinical trial may not be sufficiently broad or representative to assure safety in the full population for which we seek 
approval; 

such authorities may not accept clinical data from trials which are conducted at clinical facilities or in countries where the standard of care is potentially 
different from that of the United States; 

we are unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks; 

the FDA’s or the applicable comparable foreign regulatory agency’s non-approval of the formulation, labeling or specifications of our product candidates 
or any of our future product candidates; 

such authorities may disagree with our interpretation of data from preclinical studies or clinical trials; 

such authorities could question the integrity of data obtained in our current or future clinical trials, for example, due to missed protocol procedures;

such authorities may not agree that the data collected from clinical trials of our product candidates are acceptable or sufficient to support the submission 
of an NDA or other submission or to obtain regulatory approval in the United States or elsewhere, and such authorities may impose requirements for 
additional preclinical studies or clinical trials; 

such authorities may disagree regarding the formulation, labeling and/or the specifications of our product candidates; 

such authorities may only approve indications that are significantly more limited than what we apply for and/or with other significant restrictions on 
distribution and use; 

such authorities may find deficiencies in the manufacturing processes or facilities of our third-party manufacturers with which we or any of our 
collaborators or any potential future collaborators, contract for clinical and commercial supplies; and 

the approval policies or regulations of such authorities may significantly change in a manner rendering our or any of our collaborators’ clinical data 
insufficient for approval. 

With respect to foreign markets, approval procedures vary among countries and, in addition to the foregoing risks, may involve additional product testing, 
administrative review periods and agreements with pricing authorities. In addition, events raising questions about the safety of certain marketed pharmaceuticals may 
result in increased cautiousness by the FDA and comparable foreign regulatory authorities in reviewing new drugs based on safety, efficacy or other regulatory 
considerations and may result in significant delays in obtaining regulatory approvals. Any delay in obtaining, or inability to obtain, applicable regulatory approvals 
would prevent us or any of our collaborators or any potential future collaborators, from commercializing any products. 

60

 
 
 
 
Of the large number of drugs in development, only a small percentage successfully complete the FDA or comparable foreign regulatory approval processes and are 
commercialized. The lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to 
market our product candidates, which would significantly harm our business, financial condition, results of operations and prospects. 

Even if we eventually complete clinical trials and receive approval of an NDA or foreign marketing application for a product, the FDA or a comparable foreign 
regulatory authority may grant approval contingent on the performance of costly additional clinical trials, including Phase 4 clinical trials, and/or the implementation of 
a REMS, which may be required to ensure safe use of the drug after approval. The FDA or a comparable foreign regulatory authority also may approve a product 
candidate for a more limited indication or patient population than we originally requested, and the FDA or a comparable foreign regulatory authority may not approve 
the labeling that we believe is necessary or desirable for the successful commercialization of a product candidate. Any delay in obtaining, or inability to obtain, 
applicable regulatory approval would delay or prevent commercialization of that product candidate and would materially adversely impact our business and prospects. 

We may develop our product candidates and future product candidates in combination with other therapies, and safety or supply issues with combination-use 
products may delay or prevent development and approval of our product candidates. 

We may develop our product candidates in combination with one or more cancer therapies, both approved and unapproved. Even if any product candidate we develop 
were to receive marketing approval or be commercialized for use in combination with other existing therapies, we would continue to be subject to the risks that the 
FDA or similar regulatory authorities outside of the United States could revoke approval of the therapy used in combination with our product candidates or that safety, 
efficacy, manufacturing or supply issues could arise with these existing therapies. Combination therapies are commonly used for the treatment of cancer, and we would 
be subject to similar risks if we develop any of our product candidates for use in combination with other drugs or for indications other than cancer. Similarly, if the 
therapies we use in combination with our product candidates are replaced as the standard of care for the indications we choose for any of our product candidates, the 
FDA or similar regulatory authorities outside of the United States may require us to conduct additional clinical trials. The occurrence of any of these risks could result 
in our own products, if approved, being removed from the market or being less successful commercially. 

We may also evaluate our product candidates in combination with one or more cancer therapies that have not yet been approved for marketing by the FDA or a similar 
regulatory authority outside of the United States. We may be unable to effectively identify and collaborate with third parties for the evaluation of our product candidates 
in combination with their therapies. We will not be able to market and sell any product candidate we develop in combination with any such unapproved cancer therapies 
that do not ultimately obtain marketing approval. The regulations prohibiting the promotion of products for unapproved uses are complex and subject to substantial 
interpretation by the FDA and other foreign government agencies. In addition, there are additional risks similar to the ones described for our products currently in 
development and clinical trials that result from the fact that such cancer therapies are unapproved, such as the potential for serious adverse effects, delay in their clinical 
trials and lack of FDA or comparable foreign regulatory authorities approval. 

If the FDA or a similar regulatory authority outside of the United States does not approve these other drugs or revokes approval of, or if safety, efficacy, manufacturing, 
or supply issues arise with, the drugs we choose to evaluate in combination with any product candidate we develop, we may be unable to obtain approval of or market 
such product. 

Although we may apply for orphan drug designation for our product candidates, we may not receive the designation or we may be unable to obtain the benefits 
associated with such designation, including the potential for marketing exclusivity

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations as orphan drugs. In 
the United States, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient 
population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable 
expectation that the cost of developing the drug will be recovered from sales in the United States. In the United States, orphan drug designation entitles a party to 
financial incentives such as opportunities for grant funding, tax credits for certain clinical trial costs and user-fee waivers. If a drug with an orphan drug designation 
subsequently receives the first marketing approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which 
precludes the FDA from approving another marketing application for the same drug and indication for seven years, except in limited circumstances.

61

 
 
 
 
 
 
 
 
 
In the EU, the European Commission grants orphan designation on the basis of the EMA’s Committee for Orphan Medicinal Products opinion. A medicinal product 
may be designated as orphan if (1) it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either (a) such 
condition affects no more than five in 10,000 persons in the EU when the application is made, or (b) the product, without the benefits derived from orphan status, would 
not generate sufficient return in the EU to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment, of such condition 
authorized for marketing in the EU, or if such a method exists, the product will be of significant benefit to those affected by the condition. In the EU, orphan 
designation entitles a party to financial incentives such as reduction of fees or fee waivers, protocol assistance, and access to the centralized marketing authorization 
procedure. Moreover, upon grant of a marketing authorization and assuming the requirement for orphan designation are also met at the time the marketing authorization 
is granted, orphan medicinal products are entitled to a ten-year period of market exclusivity for the approved therapeutic indication. The period of market exclusivity is 
extended by two years for orphan medicinal products that have also complied with an agreed Pediatric Investigation Plan, or PIP. 

Although we may apply for orphan drug designation for our product candidates, we may not receive the designation we apply for. Even if we received orphan drug 
designation for one or more of our product candidates, which we have received for darovasertib in uveal melanoma, there is no guarantee that we will obtain approval 
or orphan drug exclusivity for the product. Even if we obtain approval and orphan drug exclusivity for any of our product candidates, that exclusivity may not 
effectively protect the product candidate from competition because different therapies can be approved for the same condition and the same therapy could be approved 
for different conditions. Even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if the FDA concludes that the 
later drug is clinically superior in that it is shown to provide greater safety, greater effectiveness or a major contribution to patient care. In addition, a designated orphan 
drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Moreover, orphan 
drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the 
manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. In the EU, during the exclusivity period, 
marketing authorizations may be granted to a similar medicinal product with the same orphan indication if: (i) the applicant can establish that the second medicinal 
product, although similar to the orphan medicinal product already authorized is safer, more effective or otherwise clinically superior to the orphan medicinal product 
already authorized; (ii) the marketing authorization holder for the orphan medicinal product grants its consent; or (iii) if the marketing authorization holder of the 
orphan medicinal product is unable to supply sufficient quantities of product. The European exclusivity period can be reduced to six years, if, at the end of the fifth year 
a drug no longer meets the criteria for orphan drug designation (i.e. the prevalence of the condition has increased above the orphan designation threshold or it is judged 
that the product is sufficiently profitable so as not to justify maintenance of market exclusivity). Orphan drug designation neither shortens the development time or 
regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. While we may seek additional orphan drug designations 
for applicable indications for our current and any future product candidates, we may never receive such designations. Even if we do receive such designations, there is 
no guarantee that we will enjoy the benefits of those designations.

We may seek and fail to obtain fast track or breakthrough therapy designations for our current or future product candidates. Even if we are successful, these 
programs may not lead to a faster development or regulatory review process, and they do not guarantee we will receive approval for any product candidate. 

If a product is intended for the treatment of a serious or life-threatening condition and preclinical or clinical data demonstrate the potential to address an unmet medical 
need for this condition, the product sponsor may apply for fast track designation. The sponsor of a fast track product candidate has opportunities for more frequent 
interactions with the applicable FDA review team during product development and, once an NDA is submitted, the product candidate may be eligible for priority 
review. A fast track product candidate may also be eligible for rolling review, where the FDA may consider for review sections of the NDA on a rolling basis before the 
complete application is submitted. The FDA has broad discretion whether or not to grant fast track designation, so even if we believe a particular product candidate is 
eligible for this designation, we cannot assure you that the FDA would decide to grant it. Although the FDA has granted fast track designation to darovasertib in 
combination with crizotinib for treatment of adult patients with MUM and to IDE161 for treatment of adult patients with breast cancer or ovarian cancer and we may 
seek additional designation for other product candidates in the future, we may not experience a faster development process, review or approval compared to 
conventional FDA procedures. The FDA may rescind the fast track designation if it believes that the designation is no longer supported by data from our clinical 
development program.

We may also seek breakthrough therapy designation for any product candidate that we develop. A breakthrough therapy is defined as a drug that is intended, alone or in 
combination with one or more other drugs, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug may 
demonstrate substantial improvement over 

62

 
 
 
 
 
currently approved therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For product 
candidates that have been designated as breakthrough therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the 
most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Product candidates designated as 
breakthrough therapies by the FDA may also be eligible for priority review. Like fast track designation, breakthrough therapy designation is within the discretion of the 
FDA. Accordingly, even if we believe a product candidate we develop meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead 
determine not to make such designation. In any event, the receipt of breakthrough therapy designation for a product candidate may not result in a faster development 
process, review or approval compared to drugs developed under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if a 
product candidate we develop qualifies as a breakthrough therapy, the FDA may later decide that the drug no longer meets the conditions for qualification and rescind 
the designation.

We may attempt to secure approval from the FDA through the use of the accelerated approval pathway. If we are unable to obtain such approval, we may be 
required to conduct additional preclinical studies or clinical trials beyond those that we contemplate, which could increase the expense of obtaining, and delay the 
receipt of, necessary marketing approvals. Even if we receive accelerated approval from the FDA, if our confirmatory trials do not verify clinical benefit, or if we do 
not comply with rigorous post-marketing requirements, the FDA may seek to withdraw any accelerated approval we have obtained. 

We may in the future seek accelerated approval for our one or more of our product candidates. Under the accelerated approval program, the FDA may grant accelerated 
approval to a product candidate designed to treat a serious or life-threatening condition that provides meaningful therapeutic benefit over available therapies upon a 
determination that the product candidate has an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably likely to predict clinical benefit. The 
FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful in the context of a given disease, such as irreversible morbidity or 
mortality. For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign, or other 
measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. An intermediate clinical endpoint is a clinical endpoint that can be 
measured earlier than an effect on irreversible morbidity or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical 
benefit. 

The accelerated approval pathway may be used in cases in which the advantage of a new drug over available therapy may not be a direct therapeutic advantage, but is a 
clinically important improvement from a patient and public health perspective. If granted, accelerated approval is contingent on the sponsor’s agreement to conduct, in a 
diligent manner, additional post-approval confirmatory studies to verify and describe the drug’s clinical benefit. If such post-approval studies fail to confirm the drug’s 
clinical benefit or are not completed in a timely manner, the FDA may withdraw its approval of the drug on an expedited basis. In addition, in December 2022, 
President Biden signed an omnibus appropriations bill to fund the U.S. government through fiscal year 2023 which included the Food and Drug Omnibus Reform Act 
of 2022, or FDORA. Among other things, the legislation introduced reforms intended to expand the FDA’s ability to regulate products receiving accelerated approval, 
including by increasing the FDA’s oversight over the conduct of confirmatory trials; however, the ultimate impact of these reforms remains unclear.

Prior to seeking accelerated approval for any of our product candidates, we intend to seek feedback from the FDA and will otherwise evaluate our ability to seek and 
receive accelerated approval. There can be no assurance that after our evaluation of the feedback and other factors we will decide to pursue or submit an NDA for 
accelerated approval or any other form of expedited development, review or approval. Furthermore, if we decide to submit an application for accelerated approval for 
our product candidates, there can be no assurance that such application will be accepted or that any expedited review or approval will be granted on a timely basis, or at 
all. The FDA or other comparable foreign regulatory authorities could also require us to conduct further studies prior to considering our application or granting approval 
of any type. A failure to obtain accelerated approval or any other form of expedited development, review or approval for a product candidate would result in a longer 
time period to commercialization of such product candidate, if any, could increase the cost of development of such product candidate and could harm our competitive 
position in the marketplace.

We face significant competition in an environment of rapid technological and scientific change, and our failure to effectively compete may prevent us from 
achieving significant market penetration. Most of our competitors have significantly greater resources than we do and we may not be able to successfully compete. 

The biotechnology and pharmaceutical industries in particular are characterized by rapidly advancing technologies, intense competition and a strong emphasis on 
developing proprietary therapeutics. We compete with a variety of multinational biopharmaceutical companies and specialized biotechnology companies, as well as 
technology being developed at 

63

 
 
 
 
 
 
 
universities and other research institutions. Our competitors have developed, are developing or will likely develop product candidates and processes competitive with 
our product candidates. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community and any new 
treatments that enter the market. We believe that a significant number of product candidates are currently under development, and may become commercially available 
in the future, for the treatment of diseases and other conditions for which we may try to develop product candidates. Our competitors may obtain regulatory approval of 
their products more rapidly than we may or may obtain patent protection or other intellectual property rights that limit our ability to develop or commercialize our 
product candidates. We believe that while our precision medicine target and biomarker discovery platform and our scientific and technical know-how give us a 
competitive advantage in this space, competition from many sources remains. Our competitors include larger and better funded biopharmaceutical, biotechnological and 
oncology therapeutics companies, as well as universities and other research institutions. 

Our commercial opportunity and success will be reduced or eliminated if competing products emerge that are safer, more effective, or less expensive than the 
therapeutics we develop. Our competitors may develop drugs that are more effective, more convenient, more widely used and less costly or have a better safety profile 
than our products and these competitors may also be more successful than us in manufacturing and marketing their products. 

For darovasertib, we are not aware of other companies actively developing clinical-stage therapeutics directed to PKC as a target for solid tumors. MingSight is 
developing a PKC beta inhibitor in chronic lymphocytic leukemia, or CLL, and diabetic macular edema, both in Phase 1 studies. Varian Biopharmaceuticals is 
advancing a preclinical-stage atypical PCK iota inhibitor, including as a dermatologic gel formulation for potential topical treatment of Basal Cell Carcinoma, or BCC. 
Exscientia is developing a PKC theta inhibitor in inflammatory diseases in Phase 1 studies. Varsity Pharma is developing a PKC inhibitor in CLL. We are aware of 
other companies that are conducting research and development of potential therapies for primary UM or for MUM based on other targets and approaches. For example, 
Aura Biosciences is developing AU-011 a virus-like drug conjugate (VDC) as local treatment for early-stage choroidal melanoma. Immunocore is developing and 
commercializing Tebentafusp, also known under its branded name as Kimmtrak for the treatment of adult patients with HLA-A*02:01-positive unresectable or 
metastatic uveal melanoma. Novartis is developing DYP688, an antibody-drug-conjugate, or ADC, with a GNAQ-11 inhibitor payload in a Phase 1/2 clinical trial in 
MUM.

For IDE397, Servier Pharmaceuticals, LLC, or Servier, is evaluating a small molecule MAT2A inhibitor designated as S95035 in a Phase 1 trial and Insilico Medicine 
has a small molecule MAT2A inhibitor in IND-enabling studies.

For IDE161, we are not aware of any other clinical-stage therapies targeting PARG. Several companies are conducting preclinical research to develop PARG inhibitors, 
including Nodus Oncology, SynRx, 858 Therapeutics and Satya Pharma Innovations. 

For GSK101 (IDE705), Artios Pharma is developing two clinical-stage therapies targeting Pol Theta, both in Phase 1/2 studies. Additionally, Repare Therapeutics and 
Breakpoint Therapeutics have Pol Theta inhibitors in IND-enabling studies. 

For our preclinical pipeline of synthetic lethality therapeutics, potential competition includes established companies as well as earlier-stage emerging biotechnology 
companies. Multiple established companies have been involved with research and development in synthetic lethality, such as AstraZeneca (Lynparza), Pfizer 
(Talzenna), GSK (Zejula) and Roche. Additionally, several other early-stage companies, including 858 Therapeutics, Anticancer Bioscience, Artios, Breakpoint 
Therapeutics, FoRx Therapeutics, Repare Therapeutics, Ryvu Therapeutics, Tango, Vividion, Xpose, and Eikon Therapeutics.

Development decisions and data from clinical trials of our competitors may adversely impact clinical development of our product candidates, and may additionally or 
alternatively have a material adverse impact on our financial condition or business prospects.

Furthermore, we also face competition more broadly across the market for cost-effective and reimbursable cancer treatments. The most common methods of treating 
patients with cancer are surgery, radiation and drug therapy, including chemotherapy, hormone therapy and targeted drug therapy or a combination of such methods. 
There are a variety of available drug therapies marketed for cancer. In many cases, these drugs are administered in combination to enhance efficacy. Some of these 
drugs are branded and subject to patent protection, and others are available on a generic basis. Insurers and other third-party payors may also encourage the use of 
generic products or specific branded products. We expect that if our product candidates are approved, they will be priced at a significant premium over competitive 
generic, including branded generic, products. As a result, obtaining market acceptance of, and a gaining significant share of the market for, any of our product 
candidates that 

64

 
 
 
 
 
 
 
 
 
we successfully introduce to the market will pose challenges. In addition, many companies are developing new therapeutics, and we cannot predict what the standard of 
care will be as our product candidates progress through clinical development. 

In some cases we may also develop diagnostics to enable relevant biomarker screening for clinical and commercial purposes in connection with our product candidates. 
If not already commercially available, we anticipate working in collaboration with diagnostic companies for this development, and we will face competition from other 
companies in establishing these collaborations. Our competitors will also compete with us in recruiting and retaining qualified scientific, management and commercial 
personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our 
programs. 

Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we 
successfully obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness of our products, 
the ease with which our products can be administered and the extent to which patients accept relatively new routes of administration, the timing and scope of regulatory 
approvals for these products, the availability and cost of manufacturing, marketing and sales capabilities, price, coverage, reimbursement and patent position. 
Competing products could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than 
any products we may develop. Competing products may make any products we develop obsolete or noncompetitive before we recover the expense of developing and 
commercializing our product candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our ability to 
execute our business plan. 

We expect to expand our development and regulatory capabilities and potentially implement sales and distribution capabilities, and as a result, we will need to 
increase the size of our organization, and we may experience difficulties in managing growth. 

As of December 31, 2023, we had 124 employees. We will need to continue to expand our managerial, operational, finance and other resources in order to manage our 
operations and clinical trials, continue our development activities, submit for regulatory approval and, if approved, commercialize our product candidates or any future 
product candidates. Our management and personnel, systems and facilities currently in place may not be adequate to support this future growth. Our need to effectively 
execute our growth strategy requires that we: 

•

•

•

•

manage our preclinical studies and clinical trials effectively; 

identify, recruit, retain, incentivize and integrate additional employees, including sales personnel; 

manage our internal development and operational efforts effectively while carrying out our contractual obligations to third parties; and 

continue to improve our operational, financial and management controls, reports systems and procedures.

There is no assurance that any of these increases in scale, expansion of personnel, equipment, software and computing capacities, or process enhancements will be 
successfully implemented, or that we will have adequate space in our laboratory facilities to accommodate such required expansion. 

We currently have no sales organization. If we are unable to establish sales capabilities on our own or through third parties, we may not be able to market and sell 
any products effectively, if approved, or generate product revenue. 

We currently do not have a marketing or sales organization. In order to commercialize any product, if approved, in the United States and foreign jurisdictions, we must 
build our marketing, sales, distribution, managerial and other non-technical capabilities or make arrangements with third parties to perform these services, and we may 
not be successful in doing so. In advance of any of our product candidates receiving regulatory approval, we expect to establish a sales organization with technical 
expertise and supporting distribution capabilities to commercialize each such product candidate, which will be expensive and time-consuming. We have no prior 
experience in the marketing, sale and distribution of pharmaceutical products, and there are significant risks involved in building and managing a sales organization, 
including our ability to hire, retain, and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel, and 
effectively manage a geographically dispersed sales and marketing team. Any failure or delay in the development of our internal sales, marketing and distribution 
capabilities would adversely impact the commercialization of these products. Under our GSK Collaboration Agreement, GSK will be responsible for commercialization 
of any Pol Theta or WRN products. We may choose to collaborate with additional third parties that have direct sales forces and established distribution systems, either 
to augment our own sales force and distribution systems or in lieu of our own sales force and 

65

 
 
 
 
 
 
 
 
distribution systems. If we are unable to enter into such arrangements on acceptable terms or at all, we may not be able to successfully commercialize our product 
candidates. If we are not successful in commercializing products, either on our own or through arrangements with one or more third parties, we may not be able to 
generate any future product revenue and we would incur significant additional losses. 

If we fail to attract and retain senior management and key scientific personnel, our business may be materially and adversely affected. 

Our success depends in part on our continued ability to attract, retain and motivate highly qualified management, clinical and scientific personnel. We are highly 
dependent upon our senior management, particularly our President and Chief Executive Officer, as well as our senior scientists and other members of our senior 
management team. The loss of services of any of these individuals could delay or prevent the successful development of any products, initiation or completion of our 
planned clinical trials or the commercialization of our product candidates or any other product candidates. 

Competition for qualified personnel in the biotechnology and biopharmaceutical fields is intense due to the limited number of individuals who possess the skills and 
experience required by our industry. We will need to hire additional personnel as we expand our clinical development and if we initiate commercial activities. We may 
not be able to attract and retain quality personnel on acceptable terms, or at all. In addition, to the extent we hire personnel from competitors, we may be subject to 
allegations that they have been improperly solicited or that they have divulged proprietary or other confidential information, or that their former employers own their 
research output. 

Our employees and independent contractors, including principal investigators, consultants, collaborators, service providers and other vendors may engage in 
misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have an adverse effect on our results 
of operations. 

We are exposed to the risk that our employees and independent contractors, including principal investigators, consultants, collaborators, service providers and other 
vendors may engage in misconduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or other 
unauthorized activities that violate: the laws and regulations of the FDA and other similar regulatory bodies, including those laws that require the reporting of true, 
complete and accurate information to such regulatory bodies; manufacturing standards; U.S. federal and state healthcare fraud and abuse laws, data privacy and security 
laws and other similar non-U.S. laws; or laws that require the true, complete and accurate reporting of financial information or data. Activities subject to these laws also 
involve the improper use or misrepresentation of information obtained in the course of clinical trials, the creation of fraudulent data in our preclinical studies or clinical 
trials, or illegal misappropriation of product, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify 
and deter misconduct by employees and other third-parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown 
or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such 
laws or regulations. In addition, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such 
actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business 
and financial results, including, without limitation, the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgement, 
possible exclusion from participation in Medicare, Medicaid and other U.S. federal healthcare programs or healthcare programs in other jurisdictions, integrity 
oversight and reporting obligations to resolve allegations of non-compliance, individual imprisonment, other sanctions, contractual damages, reputational harm, 
diminished profits and future earnings and curtailment of our operations, any of which could adversely affect our business, financial condition, results of operations and 
prospects. 

Our business involves the use of hazardous materials and we and our third-party manufacturers and suppliers must comply with environmental laws and 
regulations, which can be expensive and restrict how we do business. 

Our research and development activities and our third-party manufacturers’ and suppliers’ activities involve the controlled storage, use and disposal of hazardous 
materials owned by us, including the components of our product candidates and other hazardous compounds. We and any third-party manufacturers and suppliers we 
engage are subject to numerous federal, state and local environmental, health and safety laws, regulations and permitting requirements, including those governing 
laboratory procedures; the generation, handling, use, storage, treatment, and disposal of hazardous and regulated materials and wastes; the emission and discharge of 
hazardous materials into the ground, air and water; and employee health and safety. Our operations involve the use of hazardous and flammable materials, including 
chemicals and biological and radioactive materials. Our operations also produce hazardous waste. In some cases, these hazardous materials and various wastes resulting 
from their use are stored at our and our manufacturers’ facilities pending their use and disposal. We 

66

 
 
 
 
 
 
 
 
generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination, which could cause an interruption of 
our research and development efforts, commercialization efforts and business operations, environmental damage resulting in costly clean-up and liabilities under 
applicable laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. 

Although we believe that the safety procedures utilized by our third-party manufacturers for handling and disposing of these materials generally comply with the 
standards prescribed by these laws and regulations, we cannot guarantee that this is the case or eliminate the risk of accidental contamination or injury from these 
materials. Under certain environmental laws, we could be held responsible for costs relating to any contamination at our current or past facilities and at third-party 
facilities. In such an event, we may be held liable for any resulting damages and such liability could exceed our resources and state or federal or other applicable 
authorities may curtail our use of certain materials and/or interrupt our business operations. Furthermore, environmental laws and regulations are complex, change 
frequently and have tended to become more stringent. We cannot predict the impact of such changes and cannot be certain of our future compliance. 

Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair our research, 
product development and manufacturing efforts. In addition, we cannot entirely eliminate the risk of accidental injury or contamination from these materials or wastes. 
Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of 
hazardous materials and pollution insurance to cover us for certain biological or hazardous waste exposure and contamination situations, this insurance may not provide 
adequate coverage against potential liabilities. Accordingly, in the event of contamination or injury, we could be held liable for damages or be penalized with fines in an 
amount exceeding our resources, and our clinical trials or regulatory approvals could be suspended, which could have a material adverse effect on our business, 
financial condition, results of operations and prospects. 

We attempt to distribute our technology, biology, execution and financing risks across a range of therapeutic classes, disease states, programs and technologies. 
Due to the significant resources required for the development of our broad portfolio of programs, and depending on our ability to access capital, we must make 
certain risk assessments and prioritize development of certain product candidates. Moreover, we may expend our limited resources to pursue a particular product 
candidate and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success. 

Our organization is committed to a broad approach to precision medicine that seeks to maximize our integrated biomarker and small molecule drug discovery 
capabilities. Our current portfolio consists of multiple programs, extending across multiple classes of precision medicine, including direct targeting of oncogenic 
pathways and synthetic lethality. Together, these programs require significant capital investment. The directly targeted therapy programs are at various stages of 
preclinical and early clinical development, and our synthetic lethality programs are in the target identification, validation, lead optimization, and early clinical stages of 
development. We seek to maintain a process of prioritization and resource allocation to maintain an optimal balance between advancing and expanding our synthetic 
lethality and direct targeting programs. Because we have limited financial and managerial resources, we focus on specific product candidates, indications and discovery 
programs. As a result, we may forgo or delay pursuit of opportunities with other product candidates that could have had greater commercial potential. Our resource 
allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and 
development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial 
potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaborations, licenses and other 
similar arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. 

Furthermore, as our programs progress, we or others may determine: that certain of our risk allocation decisions were incorrect or insufficient; that we made platform 
level technology mistakes; that individual programs or our approach to synthetic lethality or precision medicine in general has technology or biology risks that were 
unknown or underappreciated; that our choices on how to build our organizational infrastructure to drive our expansion will result in an inability to manufacture our 
products for clinical trials or otherwise impede our manufacturing capabilities; or that we have allocated resources in such a way that large investments are not 
recovered and capital allocation is not subject to rapid re-direction. All of these risks may relate to our current or future precision medicine programs or companion 
diagnostics, and in the event material decisions in any of these areas turn out to have been incorrect or under-optimized, we may experience a material adverse impact 
on our business, financial condition, results of operations and prospects.

Public health outbreaks, epidemics or pandemics (such as the COVID-19 pandemic) may materially and adversely affect our business and operations.

67

 
 
 
 
 
 
 
The COVID-19 pandemic previously adversely affected, and the COVID-19 pandemic or other actual or threatened public health outbreaks, epidemics, or pandemics 
may in the future adversely affect, among other things, our research and development efforts, clinical trial operations, manufacturing and supply chain operations, 
administrative personnel, third-party service providers, and business partners.

While the COVID-19 pandemic did not materially adversely affect our business operations during the twelve months ended December 31, 2023, economic and health 
conditions in the United States and across most of the globe continue to change rapidly and may materially affect us economically. While the potential economic impact 
brought by, and the duration of, the COVID-19 pandemic may be difficult to assess or predict, a continuing widespread pandemic could result in significant disruption 
of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market correction 
resulting from the spread of COVID-19 or a future public health outbreak could materially affect our business and the value of our common stock. The ultimate impact 
of the COVID-19 pandemic or a similar public health outbreak is highly uncertain and subject to change. We do not yet know the full extent of potential delays or 
impacts on our business, our clinical trials, healthcare systems or the global economy as a whole. However, these effects could have a material adverse effect on our 
business, results of operations and financial condition.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain, or deploy 
key  leadership  and  other  personnel,  or  otherwise  prevent  products  from  being  developed,  approved,  or  commercialized  in  a  timely  manner  or  at  all,  which  may 
adversely affect our business.

The ability of the FDA and other government agencies to review and approve new products can be affected by a variety of factors, including government budget and 
funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the 
FDA and foreign regulatory authorities have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and 
development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies, including a prolonged 
government shutdown, or such as the European Medicines Agency following its relocation to Amsterdam and resulting staff changes, may cause significant regulatory 
delays and, therefore, delay our efforts to seek approvals and adversely affect our business, financial condition, results of operations, or cash flows. For example, over 
the last several years, the U.S. government has shut down several times, and certain regulatory agencies, such as the FDA, have had to furlough critical employees and
stop critical activities.

Additionally, in response to the COVID-19 pandemic, the FDA postponed most inspections of domestic and foreign manufacturing facilities at various points. Even 
though the FDA has since resumed standard inspection operations, any resurgence of the virus or emergence of new variants may lead to further inspectional or 
administrative delays. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA other regulatory authorities from 
conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA and other regulatory authorities to timely 
review and process our regulatory submissions, which could have a material adverse effect on our business.

We or the third parties upon whom we depend may be adversely affected by earthquakes or other natural disasters and our business continuity and disaster recovery 
plans may not adequately protect us from a serious disaster. 

Our corporate headquarters is located in the San Francisco Bay Area, which in the past has experienced both severe earthquakes and wildfires. We do not carry 
earthquake insurance. Earthquakes, wildfires or other natural disasters could severely disrupt our operations, and have a material adverse effect on our business, results 
of operations, financial condition and prospects. 

If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters or other facilities, that damaged 
critical infrastructure, such as our enterprise financial systems or manufacturing resource planning and enterprise quality systems, or that otherwise disrupted 
operations, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time. The disaster recovery and business 
continuity plans we have in place currently are limited and are unlikely to prove adequate in the event of a serious disaster or similar event. We may incur substantial 
expenses as a result of the limited nature of our disaster recovery and business continuity plans, which, particularly when taken together with our lack of earthquake 
insurance, could have a material adverse effect on our business. 

Furthermore, the third parties on which we depend, including suppliers, contract manufacturers and CROs are similarly vulnerable to natural disasters or other sudden, 
unforeseen and serious adverse events. If such an event were to affect our 

68

 
 
 
 
 
 
 
 
 
 
supply chain, manufacturing arrangements or interfere with a preclinical study or clinical trial, it could have a material adverse effect on our business. 

We are currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability due 
to the ongoing military conflict between Russia and Ukraine. Our business, financial condition and results of operations may be materially adversely affected by 
any negative impact on the global economy and capital markets resulting from the conflict in Ukraine or any other geopolitical tensions.

U.S. and global markets are experiencing volatility and disruption following the escalation of geopolitical tensions and the ongoing military conflict between Russia and 
Ukraine. In February 2022, a military invasion of Ukraine by Russian troops was reported. Following the invasion, the U.S. and global financial markets experienced 
volatility, which has led to disruptions to trade, commerce, pricing stability, credit availability and supply chain continuity globally. In response to the invasion, the 
United States, United Kingdom and European Union, along with others, imposed significant new sanctions and export controls against Russia, Russian banks and 
certain Russian individuals and may implement additional sanctions or take further punitive actions in the future. The full economic and social impact of the sanctions 
imposed on Russia (as well as possible future punitive measures that may be implemented), as well as the counter measures imposed by Russia, in addition to the 
ongoing military conflict between Ukraine and Russia and related sanctions, which could conceivably expand into the surrounding region, remains uncertain; however, 
both the conflict and related sanctions have resulted and could continue to result in disruptions to trade, commerce, pricing stability, credit availability and supply chain 
continuity in both Europe and globally, and has introduced significant uncertainty into global markets. Such risks and disruptions may negatively impact our supply 
chain, manufacturing arrangements, preclinical studies, clinical trials and our access to capital markets and ability to finance operations, which could have a materially 
adverse impact on our results of operations, financial condition and prospects.

Risks Related to Our Dependence on Third Parties 

The commercial success of our partnered product candidates in our Pol Theta and WRN programs, which are part of the GSK Collaboration Agreement, will 
depend in large part on the development and marketing efforts of GSK. If GSK is unable to perform in accordance with the terms of the GSK Collaboration 
Agreement, our potential to generate future revenue from these programs would be significantly reduced and our business would be materially and adversely 
harmed.

We will have limited influence and/or control over GSK’s approaches to development and commercialization of any Pol Theta or WRN products. While we will have 
the right to receive potential milestone, profit share and royalty streams payable as GSK or its sublicensees advance development of such Pol Theta or WRN products, 
we are likely to have limited ability to influence GSK’s development and commercialization efforts. If GSK does not perform in the manner that we expect or fulfill its 
responsibilities in a timely manner, or at all, the clinical development, regulatory approval and commercialization efforts related to product candidates we have licensed 
to GSK could be delayed or terminated. Furthermore, GSK or its licensees may elect to devote greater resources to other programs that do not relate to us or our 
collaboration.

If we terminate the GSK Collaboration Agreement, or any program thereunder due to a material breach by GSK, we have the right to assume the responsibility at our 
own expense for the development of the applicable product candidates. Assumption of sole responsibility for further development will greatly increase our 
expenditures, and may mean we need to limit the size and scope of one or more of our programs, seek additional funding and/or choose to stop work altogether on one 
or more of the affected product candidates. This could result in a limited potential to generate future revenue from such product candidates, and our business could be 
materially and adversely affected.

We rely on third parties to conduct certain of our preclinical studies and all of our clinical trials and intend to rely on third parties in the conduct of all of our 
future clinical trials. If these third parties do not successfully carry out their contractual duties, fail to comply with applicable regulatory requirements or meet 
expected deadlines, it may delay or prevent us from seeking or obtaining regulatory approval or commercializing our current or future product candidates. 

We currently do not have the ability to independently conduct preclinical studies that comply with the regulatory requirements known as good laboratory practice, or 
GLP, requirements. We also do not currently have the ability to independently conduct any clinical trials. The FDA and regulatory authorities in other jurisdictions 
require us to comply with regulations and standards, commonly referred to as GCP, requirements for conducting, monitoring, recording and reporting the results of 
clinical trials, in order to ensure that the data and results are scientifically credible and accurate and that the clinical trial patients are adequately informed of the 
potential risks of participating in clinical trials. We rely on medical institutions, clinical investigators, contract laboratories and other third parties, such as CROs, to 
conduct GLP-compliant preclinical studies and GCP-compliant clinical trials on our product candidates properly and on time. The third parties with 

69

 
 
 
 
 
 
 
 
 
whom we contract for execution of our GLP-compliant preclinical studies and our GCP-compliant clinical trials play a significant role in the conduct of these studies 
and trials and the subsequent collection and analysis of data. These third parties are not our employees and, except for restrictions imposed by our contracts with such 
third parties, we have limited ability to control the amount or timing of resources that they devote to our programs. Although we rely on these third parties to conduct 
our GLP-compliant preclinical studies and GCP-compliant clinical trials, we remain responsible for ensuring that each of our GLP preclinical studies and clinical trials 
is conducted in accordance with its investigational plan and protocol and applicable laws and regulations, and our reliance on the CROs does not relieve us of our 
regulatory responsibilities.

Many of the third parties with whom we contract may also have relationships with other commercial entities, including our competitors, for whom they may also be 
conducting clinical trials or other drug development activities that could harm our competitive position. Further, some of these agreements may also be terminated by 
such third parties on short notice, or under certain circumstances, including our insolvency. If the third parties conducting our preclinical studies or our clinical trials do 
not adequately perform their contractual duties or obligations, experience significant business challenges, disruptions or failures, do not meet expected deadlines, 
terminate their agreements with us or need to be replaced, or if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to our 
protocols or to GCPs, or for any other reason, we may need to enter into new arrangements with alternative third parties. This could be difficult, costly or impossible, 
and our preclinical studies or clinical trials may need to be extended, delayed, terminated or repeated. As a result, we may not be able to obtain regulatory approval in a 
timely fashion, or at all, for the applicable product candidate, and our business, financial position, results of operations and prospects may be adversely affected. 

We rely on third parties for the manufacture of our product candidates for preclinical and clinical development and expect to continue to do so for the foreseeable 
future. This reliance on third parties increases the risk that we will not have sufficient quantities of our product candidates or products or such quantities at an 
acceptable cost, which could delay, prevent or impair our development or commercialization efforts. 

We do not own or operate manufacturing facilities and have no plans to build our own clinical or commercial scale manufacturing capabilities. We rely, and expect to 
continue to rely, on third parties for the manufacture of our product candidates and related raw materials for preclinical and clinical development, as well as for 
commercial manufacture of any future approved products. The facilities used by third-party manufacturers to manufacture our product candidates must be approved by 
the FDA pursuant to inspections that will be conducted after we submit our NDA to the FDA. We do not control the manufacturing process of, and are completely 
dependent on, third-party manufacturers for compliance with cGMP requirements or similar applicable foreign requirements for manufacture of drug products. If these 
third-party manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or other 
comparable foreign regulatory authorities, including requirements related to the manufacturing of high potency compounds, they will not be able to secure and/or 
maintain regulatory approval for their manufacturing facilities. These third-party manufacturers may be delayed in their manufacture or shipment of our product 
candidates due to public health outbreaks, heightened geopolitical conflict, increases in inflation and interest rates, or supply chain disruptions. For example, 
deterioration in the relationship between the United States and the PRC may impact international trade, government spending, regional stability and macroeconomic 
conditions. The impact of these potential developments, including any resulting sanctions, export controls or other restrictive actions that may be imposed against 
governmental or other entities in, for example, the PRC, may contribute to disruption of our PRC-based third-party suppliers and instability and volatility in the global 
markets, which in turn could adversely impact our operations and weaken our financial results. Additionally, our ability to audit these third-party manufacturers for 
compliance with cGMP requirements or similar foreign requirements (where applicable) and our specifications may be hindered or delayed due to a public health 
outbreak or geopolitical conditions.

In addition, we have no control over the ability of third-party manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA 
or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the 
future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our 
product candidates, if approved. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being 
imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, seizures or recalls of product candidates or 
products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our products. 

In addition, we may be unable to establish or renew any agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish 
agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including: 

70

 
 
 
 
 
 
•

•

•

•

•

•

failure of third-party manufacturers to comply with regulatory requirements and maintain quality assurance; 

breach of the manufacturing agreement by the third-party; 

failure to manufacture our product according to our specifications; 

failure to manufacture our product according to our schedule or at all; 

misappropriation of our proprietary information, including our trade secrets and know-how; and 

termination or nonrenewal of the agreement by the third-party at a time that is costly or inconvenient for us. 

Our product candidates and any products that we may develop may compete with other product candidates and products for access to manufacturing facilities. There are 
a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us, particularly if the COVID-19 pandemic, 
geopolitical conflict and macroeconomic concerns continue or worsen.

Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval, and any related remedial measures 
may be costly or time-consuming to implement. We do not currently have arrangements in place for redundant supply or a second source for all required raw materials 
used in the manufacture of our product candidates. If our current third-party manufacturers cannot perform as agreed, we may be required to replace such manufacturers 
and we may be unable to replace them on a timely basis or at all. 

We rely on, and in the future may rely on, third-party databases and collaborations with third parties to inform patient selection and drug target identification for 
our existing product candidates and any future product candidates and for the supply of biomarker companion diagnostics.

We are using bioinformatics, including data analytics, biostatistics, and computational biology, to identify new target and biomarker opportunities. As part of this 
approach, we interrogate public and proprietary databases comprising human tumor genetic information and specific cancer-target dependency networks. We rely on 
these databases and data analytics for identifying or validating some of our biomarker-target relationships and access to these databases may not continue to be available 
publicly or through a proprietary subscription on acceptable terms. 

Many of our precision medicine targeted therapeutic product candidates also rely on the availability and use of commercially available tumor diagnostics panels or data 
on the prevalence of our target patient population to inform the patient selection and drug target identification for our product candidates. In cases where such biomarker 
diagnostic is not already commercially available, we expect to establish strategic collaborations for the clinical supply and development of companion diagnostics. If 
these diagnostics are not able to be developed, or if commercial tumor profiling panels are not able to be updated to include additional tumor-associated genes, or if 
clinical oncologists do not incorporate molecular or genetic sequencing into their clinical practice, we may not be successful in developing our existing product 
candidates or any future product candidates. 

We depend on third-party suppliers for key materials required for the production of our product candidates, and the loss of these third-party suppliers or their 
inability to supply us with adequate materials could harm our business. 

We rely on third-party suppliers for certain materials, such as starting reagents, required for the production of our product candidates and/or for certain materials and 
assays, such as diagnostics, for clinical and commercial use of our product candidates. Our dependence on these third-party suppliers and the challenges we may face in 
obtaining adequate supplies of materials involve several risks, including limited control over pricing, availability, quality and delivery schedules. As a small company, 
our negotiation leverage is limited and we are likely to get lower priority than our competitors that are larger than we are. We cannot be certain that our suppliers will 
continue to provide us with the quantities of these raw materials that we require or satisfy our anticipated specifications and quality requirements. Any supply 
interruption in limited or sole sourced raw materials could materially harm our ability to manufacture our product candidates until a new source of supply, if any, could 
be identified and qualified. We may be unable to find a sufficient alternative supply channel in a reasonable time or on commercially reasonable terms. Any 
performance failure on the part of our suppliers could delay the development and potential commercialization of our product candidates, including limiting supplies 
necessary for clinical trials and regulatory approvals, which would have a material adverse effect on our business. 

Additionally, the facilities to manufacture our product candidates must be the subject of a satisfactory inspection before the FDA or other regulatory authorities approve 
an NDA or grant a marketing authorization for the product candidate manufactured at that facility. We will depend on these third-party manufacturing partners for 
compliance with the FDA’s 

71

 
 
 
 
 
 
 
 
 
requirements for the manufacture of our finished products. If our manufacturers cannot successfully manufacture material that conforms to our specifications and the 
FDA’s and other regulatory authorities’ GMP requirements, our product candidates will not be approved or, if already approved, may be subject to recalls.

Furthermore, certain of the third-party suppliers on which we rely are based in the PRC. The evolving trade dispute between the PRC and the United States has resulted 
in the imposition of significant tariffs on certain imports from the PRC. Any deterioration of the relationship between the United States and the PRC, or the imposition 
of more stringent export controls or tariffs applicable to our suppliers in the PRC, could adversely affect our ability to obtain the raw materials required for the 
manufacture of our product candidates, and therefore adversely affect our business, financial condition, results of operations and prospects. 

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured the product candidates ourselves, including: 

•

•

•

the possibility of a breach of the manufacturing agreements by the third parties because of factors beyond our control; 

the possibility of termination or nonrenewal of the agreements by the third parties before we are able to arrange for a qualified replacement third-party 
manufacturer; and 

the possibility that we may not be able to secure a manufacturer or manufacturing capacity in a timely manner and on satisfactory terms in order to meet 
our manufacturing needs. 

Any of these factors could cause the delay of approval or commercialization of any products, cause us to incur higher costs or prevent us from commercializing any 
products successfully. Furthermore, if any of our product candidates are approved and contract manufacturers fail to deliver the required commercial quantities of 
finished product on a timely basis and at commercially reasonable prices, and we are unable to find one or more replacement manufacturers capable of production at a 
substantially equivalent cost, in substantially equivalent volumes and quality and on a timely basis, we would likely be unable to meet demand for our products and 
could lose potential revenue. It may take several years to establish an alternative source of supply for our product candidates and to have any such new source approved 
by the FDA or any other relevant regulatory authority. 

If we fail to comply with our obligations under any of our in-license agreements, we could lose license rights that are important to our business. 

Our current in-license agreements or any future in-license agreements provide or may provide that we must use reasonable efforts to obtain regulatory approval for a 
product candidate using the licensed compound. The agreements further impose or may impose an obligation to make various milestone payments and royalty payments 
as well as other obligations on us. If we materially breach the terms of any in-license agreement and fail to cure such breach within the period allowed, then the licensor 
may terminate the license agreement. In addition, the licensor has or may have the right to terminate on our insolvency. If the agreement is terminated, then we will not 
be able to further develop or commercialize the licensed compound or any future related product candidates. 

Furthermore, any dispute with the licensor may result in the delay or termination of the research, development or commercialization of the licensed compound or any 
future related product candidates, and may result in costly litigation or arbitration that diverts management attention and resources away from our day-to-day activities, 
which may adversely affect our business, financial condition, results of operations and prospects.

Our existing collaboration arrangements and any collaboration arrangements that we may enter into in the future may not be successful, which could adversely 
affect our ability to develop and commercialize our product candidates or diagnostics associated with such product candidates. 

In the future, we may seek to enter into additional collaboration arrangements for the development or commercialization of certain of our product candidates or 
diagnostics for biomarkers associated with our product candidates. To the extent that we decide to enter into additional collaboration agreements in the future, we may 
face significant competition in seeking appropriate collaborators. Moreover, collaboration arrangements are complex and time-consuming to negotiate, document, 
implement and maintain and challenging to manage. We may not be successful in our efforts to prudently manage our existing collaborations or to enter new ones 
should we chose to do so. The terms of new collaborations or other arrangements that we may establish may not be favorable to us. 

72

 
 
 
 
 
 
 
 
 
 
The success of our collaboration arrangements, including our GSK Collaboration Agreement, will depend heavily on the efforts and activities of our collaborators. 
Collaborations are subject to numerous risks, which may include risks that:

•

•

•

•

•

•

•

•

•

•

•

•

collaborators may have significant discretion in determining the efforts and resources that they will apply to collaborations; 

collaborators may not pursue development and commercialization of our product candidates or may elect not to continue or renew development or 
commercialization programs based on clinical trial results, changes in their strategic focus due to their acquisition of competitive products or their 
internal development of competitive products, availability of funding or other external factors, such as a business combination that diverts resources or 
creates competing priorities; 

collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial, abandon a product candidate, repeat 
or conduct new clinical trials or require a new formulation of a product candidate for clinical testing; 

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our products or product 
candidates; 

a collaborator with marketing, manufacturing and distribution rights to one or more products may not commit sufficient resources to or otherwise not 
perform satisfactorily in carrying out these activities; 

we could grant exclusive rights to our collaborators that would prevent us from collaborating with others; 

collaborators may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a 
way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us 
to potential liability; 

disputes may arise between us and a collaborator that cause the delay or termination of the research, development or commercialization of our current or 
future product candidates or that results in costly litigation or arbitration that diverts management attention and resources; 

collaborations may be terminated, which may result in a need for additional capital to pursue further development or commercialization of the applicable 
current or future product candidates; 

collaborators may own or co-own intellectual property covering products that result from our collaboration with them, and in such cases, we would not 
have the exclusive right to develop or commercialize such intellectual property; 

disputes may arise with respect to the ownership or inventorship of any intellectual property developed pursuant to our collaborations; and 

a collaborator’s sales and marketing activities or other operations may not be in compliance with applicable laws resulting in civil or criminal 
proceedings. 

Risks Related to Commercialization of Our Product Candidates 

Even if we receive regulatory approval for any product candidate, we will be subject to ongoing regulatory obligations and continued regulatory review, which may 
result in significant additional expense. Additionally, our product candidates, if approved, could be subject to labeling and other restrictions on marketing or 
withdrawal from the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with 
our product candidates, when and if any of them are approved. 

If one of our product candidates is approved, it will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, 
promotion, sampling, record-keeping, conduct of post-marketing studies, and submission of safety, efficacy, and other post-market information, including both federal 
and state requirements in the United States and requirements of comparable foreign regulatory authorities. 

For example, the FDA or similar foreign regulatory authorities may impose significant restrictions on a product’s indicated uses or marketing or impose ongoing 
requirements for potentially costly and time-consuming post-approval studies, post-market surveillance or clinical trials to monitor the safety and efficacy of the 
product candidate. The FDA may also require a REMS as a condition of approval of our product candidates, which could include requirements for a medication guide, 
physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient 

73

 
 
 
 
 
registries and other risk minimization tools. Similar requirements may apply in foreign jurisdictions. In addition, if the FDA or a comparable foreign regulatory 
authority approves our product candidates, the manufacturing processes, labeling, packaging, distribution, AE reporting, storage, advertising, promotion, import, export 
and recordkeeping for our product candidates will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and 
other post-marketing information and reports, registration, as well as continued compliance with cGMPs or similar foreign requirements and GCP requirements for any 
clinical trials that we conduct post-approval. Later discovery of previously unknown problems with our product candidates, including AEs of unanticipated severity or 
frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

•

•

•

•

•

•

•

suspension or withdrawal of regulatory approval, restrictions on the marketing or manufacturing of our product candidates, withdrawal of the product 
from the market, or voluntary or mandatory product recalls; 

restrictions on product distribution or use, or requirements to conduct post-marketing studies or additional clinical trials; 

suspension of any of our ongoing clinical trials; 

fines, restitutions, disgorgement of profits or revenues, warning letters, untitled letters or holds on clinical trials; 

refusal by the FDA or comparable foreign regulatory authorities to approve pending applications or supplements to approved applications filed by us or 
suspension or revocation of approvals; 

product seizure or detention, or refusal to permit the import or export of our product candidates; and 

injunctions or the imposition of civil or criminal penalties. 

The occurrence of any event or penalty described above may inhibit our ability to commercialize any future approved product and generate revenue and could require 
us to expend significant time and resources in response and could generate negative publicity.

In addition, if any of our product candidates is approved, our product labeling, advertising and promotion will be subject to regulatory requirements and continuing 
regulatory review. The FDA strictly regulates the promotional claims that may be made about drug products. In particular, a product may not be promoted for uses that 
are not approved by the FDA as reflected in the product’s approved labeling. Similar requirements may apply in foreign jurisdictions. If we receive marketing approval 
for a product, physicians may nevertheless prescribe it to their patients in a manner that is inconsistent with the approved label. If we are found to have promoted such 
off-label uses, we may become subject to significant liability. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-
label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant sanctions. The federal government has levied large 
civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also 
requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. 

The FDA’s and other regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory 
approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are 
not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability. 

The incidence and prevalence of our target patient populations are estimations. If the market opportunities for our product candidates are smaller than we 
estimate, our business, financial position, results of operations and prospects may be harmed. 

We rely on various sources, including published literature and public or proprietary databases, to ascertain an estimate of the number of patients having particular 
genetic alterations, such as mutations, deletions or fusions, across various tissue-type specific indications. The determinable prevalence may vary depending on the 
source and quality of the underlying data and in some cases, insufficient data or poorly curated data may impact our ability to accurately estimate the prevalence of our 
target patient populations for each indication and in the aggregate across multiple indications both in the clinical trial setting, as well as in the commercial setting, if our 
product is approved. If the market opportunities for our product candidates are smaller than we estimate, our business, financial position, results of operations and 
prospects may be harmed. In addition, upon treatment with our product candidates, patients may have or develop resistance to our product candidates, reducing the 
addressable patient population and the duration of treatment. 

74

 
 
 
 
 
 
Even if our product candidates or any future product candidate obtains regulatory approval, they may fail to achieve the broad degree of physician and patient 
adoption and use necessary for commercial success. 

Even if our product candidates or any future product candidate receives FDA or other regulatory approvals, the commercial success of any product will depend 
significantly on the broad adoption and use of the resulting product by physicians and patients for approved indications. For a variety of reasons, including among other 
things, competitive factors, pricing or physician preference, reimbursement by insurers, the degree and rate of physician and patient adoption of any products, if 
approved, will depend on a number of factors, including: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the clinical indications for which the product is approved and patient demand for approved products that treat those indications; 

the safety and efficacy of our product as compared to other available therapies; 

the availability of companion diagnostics for biomarkers associated with our product candidates or any other future product candidates; 

the time required for manufacture and release of our products; 

the availability of coverage and adequate reimbursement from managed care plans, private insurers, government payors (such as Medicare and 
Medicaid) and other third-party payors for any of our products that may be approved; 

acceptance by physicians, operators of hospitals and clinics and patients of the product as a safe and effective treatment; 

physician and patient willingness to adopt a new therapy over other available therapies for a particular indication; 

proper training and administration of our product candidates by physicians and medical staff; 

patient satisfaction with the results and administration of our product candidates and overall treatment experience, including, for example, the 
convenience of any dosing regimen; 

the cost of treatment with our product candidates in relation to alternative treatments and reimbursement levels, if any, and willingness to pay for the 
product, if approved, on the part of insurance companies and other third-party payors, physicians and patients; 

the prevalence and severity of side effects;

limitations or warnings contained in the FDA-approved labeling for our products or similar foreign requirements; 

the willingness of physicians, operators of hospitals and clinics and patients to utilize or adopt our products as a solution; 

any FDA requirement for a REMS or similar foreign risk mitigation measures; 

the effectiveness of our sales, marketing and distribution efforts; 

adverse publicity about our products or favorable publicity about competitive products; and 

potential product liability claims. 

We cannot assure you that our current or future product candidates, if approved, will achieve broad market acceptance among physicians and patients. Any failure by 
our product candidates that obtain regulatory approval to achieve market acceptance or commercial success would adversely affect our business, financial condition, 
results of operations and prospects. 

The successful commercialization of any products will depend in part on the extent to which governmental authorities, private health insurers, managed care plans 
and other third-party payors provide coverage, adequate reimbursement levels and implement pricing policies favorable for any products. Failure to obtain or 
maintain coverage and adequate reimbursement for products, if approved, could limit our ability to market those products and decrease our ability to generate 
revenue. 

The availability of coverage and adequacy of reimbursement by governmental healthcare programs, such as Medicare and Medicaid, private health insurers, managed 
care plans and other third-party payors are essential for most patients to be able to afford medical services and pharmaceutical products such as our product candidates 
that receive FDA approval. Our ability to 

75

 
 
 
 
 
 
achieve acceptable levels of coverage and reimbursement by third-party payors for our products will have an effect on our ability to successfully commercialize our 
product candidates. 

No uniform policy for coverage and reimbursement for products exists among third-party payors in the United States. Therefore, coverage and reimbursement for 
products can differ significantly from payor to payor. The process for determining whether a third-party payor will provide coverage for a product typically is separate 
from the process for setting the price of such product or for establishing the reimbursement rate that the payor will pay for the product once coverage is approved. 
Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the FDA-approved products 
for a particular indication, or place products at certain formulary levels that result in lower reimbursement levels and higher cost-sharing obligation imposed on patients. 
One third-party payor’s decision to cover a particular medical product or service does not ensure that other payors will also provide coverage for the medical product or 
service. As a result, the coverage determination process will often require us to provide scientific and clinical support for the use of our products to each payor 
separately and can be a time-consuming process, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first 
instance. We cannot be sure that coverage will be available for any product that we may develop. A decision by a third-party payor not to cover any of our product 
candidates could reduce physician utilization of our products once approved and adversely affect our business, financial condition, results of operations and prospects. 

Assuming there is coverage for our products, if any, by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments 
that patients find unacceptably high. Furthermore, rules and regulations regarding reimbursement change frequently, in some cases on short notice, and we believe that 
changes in these rules and regulations are likely. 

Third-party payors increasingly are challenging prices charged for pharmaceutical products and services, and many third-party payors may refuse to provide coverage 
and reimbursement for particular drugs or biologics when an equivalent generic drug, biosimilar or a less expensive therapy is available. It is possible that a third-party 
payor may consider our product candidates as substitutable and only offer to reimburse patients for the less expensive product. Even if we show improved efficacy or 
improved convenience of administration with our products, pricing of other third-party therapeutics may limit the amount we will be able to charge for our products. 
These third-party payors may deny or revoke the reimbursement status of our products, if approved, or establish prices for our products at levels that are too low to 
enable us to realize an appropriate return on our investment. If reimbursement is not available, is decreased or eliminated in the future, or is available only at limited 
levels, we may not be able to successfully commercialize our products and may not be able to obtain a satisfactory financial return on our products. 

Outside the United States, international operations are generally subject to extensive governmental price controls and other market regulations, and we believe the 
increasing emphasis on cost-containment initiatives in Europe and other countries has and will continue to put pressure on the pricing and usage of our products, if any. 
In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to
fix their own prices for medical products but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict 
the amount that we are able to charge for our products. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared 
with the United States and may be insufficient to generate commercially reasonable revenue and profits. 

Moreover, increasing efforts by governmental and third-party payors in the United States and abroad to cap or reduce healthcare costs may cause such organizations to 
limit both coverage and the level of reimbursement for newly approved products, and, as a result, they may not cover or provide adequate payment for our products. We 
expect to experience pricing pressures in connection with the sale of our product candidates due to the trend toward managed health care, the increasing influence of 
health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and 
biologics and surgical procedures and other treatments, has become intense. As a result, increasingly high barriers are being erected to the entry of new products. 

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of any products. 

We face an inherent risk of product liability as a result of the planned clinical trials of our product candidates and will face an even greater risk if we commercialize any 
products. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during product testing, manufacturing, 
marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the 
product, negligence, strict liability, and a breach of warranty. Claims could also be asserted under state consumer 

76

 
 
 
 
 
 
 
 
protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization 
of any products. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims 
may result in: 

•

•

•

•

•

•

•

•

•

decreased demand for any products; 

injury to our reputation; 

withdrawal of clinical trial participants; 

costs to defend the related litigation; 

a diversion of management’s time and our resources; 

substantial monetary awards to clinical trial participants or patients; 

regulatory investigations, product recalls, withdrawals or labeling, marketing or promotional restrictions; 

loss of revenue; and 

the inability to commercialize any products. 

Our inability to obtain and maintain sufficient product liability insurance at an acceptable cost and scope of coverage to protect against potential product liability claims 
could prevent or inhibit the commercialization of any products. Although we have obtained and intend to maintain product liability insurance covering our clinical 
trials, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or 
that is in excess of the limits of our insurance coverage. Our insurance policies also have various exclusions and deductibles, and we may be subject to a product 
liability claim for which we have no coverage. We will have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or 
that are not covered by our insurance, and we may not have, or be able to obtain, sufficient funds to pay such amounts. Moreover, in the future, we may not be able to 
maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. If and when we obtain approval for marketing any of our product 
candidates, we intend to expand our insurance coverage to include the sale of such product candidate; however, we may be unable to obtain this liability insurance on 
commercially reasonable terms or at all. 

Risks Related to Intellectual Property 

Our success depends on our ability to obtain and maintain protection for our intellectual property and our proprietary technologies and to avoid infringing the 
rights of others. 

Our commercial success depends in part on our ability to obtain and maintain patent, trademark, trade secret and other intellectual property protection for our product 
candidates and proprietary technologies as well as our ability to operate without infringing upon the proprietary rights of others. 

We and our licensors have applied, and we intend to continue applying, for patents covering important aspects of our product candidates, proprietary technologies and 
their uses as we deem appropriate. However, the patent prosecution process is expensive, time-consuming and complex, and we may not be able to apply for patents on 
certain aspects of our current or future product candidates and proprietary technologies in a timely fashion, at a reasonable cost, in all jurisdictions, or at all. If we 
cannot adequately obtain, maintain and enforce our intellectual property rights and proprietary technology, competitors may be able to use our technologies or the 
goodwill we have acquired in the marketplace and erode or negate any competitive advantage we may have and our ability to compete, which could harm our business 
and ability to achieve profitability and/or cause us to incur significant expenses. Failure to obtain, maintain and/or enforce intellectual property rights necessary to our 
business and failure to protect, monitor and control the use of our intellectual property rights could negatively impact our ability to compete and cause us to incur 
significant expenses. The intellectual property laws and other statutory and contractual arrangements in the United States and other jurisdictions we depend upon may 
not provide sufficient protection in the future to prevent the infringement, use, violation or misappropriation of our patents, trademarks, data, technology and other 
intellectual property rights and products by others, and may not provide an adequate remedy if our intellectual property rights are infringed, misappropriated or 
otherwise violated by others.

Our patent applications cannot be enforced against third parties practicing the inventions claimed in such applications unless, and until, patents issue from such 
applications, and then only to the extent the issued claims cover the invention as claimed. The patent application process is subject to numerous risks and uncertainties, 
and there can be no assurance that we or any of 

77

 
 
 
 
 
 
 
our actual or potential future collaborators or licensors will be successful in protecting our product candidates and proprietary technologies by obtaining and defending 
patents. These risks and uncertainties include the following: 

•

•

•

•

•

•

•

•

•

the United States Patent and Trademark Office, or USPTO, and various foreign governmental patent agencies require compliance with a number of 
procedural, documentary, fee payment and other requirements during the patent process, the noncompliance with which can result in abandonment or 
lapse of a patent or patent application, and partial or complete loss of patent rights in the relevant jurisdiction; 

patent applications may not result in any patents being issued; 

our competitors, many of whom have substantially greater resources than we do and many of whom have made significant investments in competing 
technologies, may seek or may have already obtained or licensed patents that will limit, interfere with or eliminate our ability to make, use and sell our 
product candidates; 

other parties may have designed or may design around our claims or developed technologies that may be related or competitive to our platform, may 
have filed or may file patent applications and may have received or may receive patents that overlap or conflict with our patent applications, either by 
claiming the same methods or devices or by claiming subject matter that could dominate our patent position; 

any successful opposition to any patents owned by or licensed to us could deprive us of rights necessary for the practice of our technologies or the 
successful commercialization of any product candidates that we may develop;

because patent applications in the United States and most other countries are confidential for a period of time after filing, we cannot be certain that we or 
our licensors were the first to file any patent application related to our product candidates and proprietary technologies; 

an interference proceeding can be provoked by a third-party or instituted by the USPTO to determine who was the first to invent any of the subject 
matter covered by the patent claims of our applications for any application with an effective filing date before March 16, 2013; 

there may be significant pressure on the U.S. government and international governmental bodies to limit the scope of patent protection both inside and 
outside the United States for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns; and 

countries other than the United States may have patent laws less favorable to patentees than those upheld by U.S. courts, allowing foreign competitors a 
better opportunity to create, develop and market competing product candidates. 

We rely in part on our portfolio of issued and pending patent applications in the United States and other countries to protect our intellectual property and competitive 
position. The patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of 
much litigation in recent years. It is possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent 
protection. If we fail to timely file for patent protection in any jurisdiction, we may be precluded from doing so at a later date. And although we enter into non-
disclosure and confidentiality agreements with parties who have access to patentable aspects of our research and development output, such as our employees, corporate 
collaborators, outside scientific collaborators, CROs, contract manufacturers, consultants, advisors and other third parties, any of these parties may breach such 
agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. Furthermore, publications of 
discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not 
published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in any of our 
patents or pending patent applications, or that we were the first to file for patent protection of such inventions. Moreover, should we become a licensee of a third-party’s 
patents or patent applications, depending on the terms of any future in-licenses to which we may become a party, we may not have the right to control the preparation, 
filing and prosecution of patent applications, or to maintain or enforce the patents, covering technology in-licensed from third parties. Therefore, these patents and 
patent applications may not be prosecuted, maintained and/or enforced in a manner consistent with the best interests of our business. Any of these outcomes could 
impair our ability to prevent competition from third parties, which may have an adverse impact on our business. 

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability and it may not provide us with adequate proprietary protection or 
competitive advantages against competitors with similar products or services. Accordingly, we cannot provide any assurances about which of our patent applications 
will issue, the breadth of any resulting patent, whether any of the issued patents will be found to be infringed, invalid or unenforceable or will be threatened or 

78

 
 
 
challenged by third parties, that any of our issued patents have, or that any of our currently pending or future patent applications that mature into issued patents will 
include, claims with a scope sufficient to protect our products and services. The coverage claimed in a patent application can be significantly reduced before the patent 
is issued, and its scope can be reinterpreted after issuance. We cannot offer any assurances that the breadth of our granted patents will be sufficient to stop a competitor 
from developing, manufacturing and commercializing a product or technologies in a non-infringing manner that would be competitive with one or more of our products 
or technologies, or otherwise provide us with any competitive advantage. Further, our patents or the patent rights that we license from others, may be challenged in the 
courts or patent offices in the United States and abroad. Once granted, patents may remain open to opposition, interference, re-examination, post-grant review, inter 
partes review, nullification or derivation action or similar proceedings in court or before patent offices in the United States or foreign jurisdictions for a given period 
after allowance or grant, during which time third parties can raise objections against such patents. Such challenges may result in loss of exclusivity or in patent claims 
being narrowed, invalidated or held unenforceable, all of which could limit our ability to stop others from using or commercializing similar or identical product 
candidates, or limit the duration of the patent protection of our product candidates. In addition, defending such challenges in such proceedings may be costly. Further, 
there can be no assurance that we will have adequate resources to enforce our patents. Thus, any patents that we may own may not provide the anticipated level of, or 
any, protection against competitors. Furthermore, an adverse decision may result in a third-party receiving a patent right sought by us, which in turn could affect our 
ability to develop, manufacture or commercialize our products or technologies.

The degree of future protection for our patent rights is uncertain, and we cannot ensure that: 

•

•

•

•

•

•

•

•

•

•

•

•

any of our patents, or any of our pending patent applications, if issued, or those of our licensors, will include claims having a scope sufficient to protect 
our product candidates; 

any of our pending patent applications will issue as patents;

any of the patents we own or license will be found to ultimately be valid and enforceable if subject to challenge; 

we were the first to make the inventions covered by each of our patents and pending applications;

we were the first to file patent applications for these inventions;

we will be able to successfully manufacture and commercialize our products on a substantial scale, if approved, before relevant patents we may have 
expire;

any patents issued to us or our licensors will provide a basis for an exclusive market for any commercially viable products we may develop or will 
provide us with any competitive advantages; 

we will develop or in-license additional proprietary technologies that are patentable; 

the patents of others will not have an adverse effect on our business; 

others will not develop, manufacture and/or commercialize similar or alternative products or technologies that do not infringe our patents;

our competitors do not conduct research and development activities in countries where we do not have enforceable patent rights and then use the 
information learned from such activities to develop competitive products for sale in our major commercial markets; and 

our commercial activities or products will not infringe upon the patents of others.

Our ability to enforce patent rights also depends on our ability to detect infringement. It may be difficult to detect infringers who do not advertise the components or 
methods that are used in connection with their products and services. Such proceedings could also provoke third parties to assert claims against us, including that some 
or all of the claims in one or more of our patents are invalid or otherwise unenforceable. Moreover, it may be difficult or impossible to obtain evidence of infringement 
in a competitor’s or potential competitor’s product or service. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded if we were 
to prevail may not be commercially meaningful. If we initiate lawsuits to protect or enforce our patents, or litigate against third-party claims, such proceedings would be 
expensive and would divert the attention of our management and technical personnel. 

Where we obtain licenses from or collaborate with third parties, in some circumstances, we may not have the right to control the preparation, filing and prosecution of 
patent applications, or to maintain the patents, covering technology that we license from third parties, or such activities, if controlled by us, may require the input of 
such third parties. We may also require the cooperation of our licensors and collaborators to enforce any licensed patent rights, and such cooperation may not be 

79

 
 
 
 
provided. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. Moreover, if we 
do obtain necessary licenses, we will likely have obligations under those licenses, and any failure to satisfy those obligations could give our licensor the right to 
terminate the license. Termination of a necessary license, or expiration of licensed patents or patent applications, could have a material adverse impact on our 
competitive position, business, financial condition, results of operations and prospects. 

Some of our patents and patent applications may in the future be co-owned with third parties. If we are unable to obtain an exclusive license to any such third-party co-
owners’ interest in such patents or patent applications, such co-owners may be able to license their rights to other third parties, including our competitors, and our 
competitors could market competing products, services and technology. In addition, we may need the cooperation of any such co-owners of our patents in order to 
enforce such patents against third parties, and such cooperation may not be provided to us.

Furthermore, our owned and in-licensed intellectual property rights may be subject to a reservation of rights by one or more third parties. For example, the research 
resulting in certain of our owned and in-licensed patent rights and technology was funded in part by the U.S. government. As a result, the government may have certain 
rights, or march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the government generally obtains 
certain rights in any resulting patents, including a non-exclusive license authorizing the government to use the invention for non-commercial purposes. These rights 
may permit the government to disclose our confidential information to third parties and to exercise march-in rights to use or allow third parties to use our licensed 
technology. The government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-
funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In 
addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United States. Any exercise by 
the government of such rights could harm our competitive position, business, financial condition, results of operations, and prospects. 

Further, we rely on a combination of contractual provisions, confidentiality procedures and patent, trademark, copyright, trade secret and other intellectual property 
laws to protect the proprietary aspects of our products, brands, technologies, trade secrets, know-how and data. These legal measures afford only limited protection, and 
competitors or others may gain access to or use our intellectual property rights and proprietary information. Our success will depend, in part, on preserving our trade 
secrets, maintaining the security of our data and know-how and obtaining, maintaining and enforcing other intellectual property rights. We may not be able to obtain, 
maintain and/or enforce our intellectual property or other proprietary rights necessary to our business or in a form that provides us with a competitive advantage.

If we fail to obtain sufficient patent or other intellectual property protection for our product candidates or proprietary technologies or if we lose any patent or other 
intellectual property protection for our product candidates or proprietary technologies, our business, financial condition, results of operations and prospects could be 
adversely affected. 

If we do not obtain patent term extension in the United States under the Hatch-Waxman Act and in foreign countries under similar legislation for patents covering 
our product candidates, our business may be materially harmed, and in any case, the terms of our patents may not be sufficient to effectively protect our product 
candidates and business. 

Patents have a limited term. In most countries, including the United States, the expiration of a patent is generally 20 years after its first effective non-provisional filing 
date. However, depending upon the timing, duration and specifics of FDA marketing approval of darovasertib, IDE397, our other product candidates or any future 
product candidates, one or more of any U.S. patents we may be issued or have licensed may be eligible for limited patent term restoration under the Drug Price 
Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Amendments. 

The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA 
regulatory review process. The Hatch-Waxman Act allows a maximum of one patent to be extended per FDA-approved product as compensation for the patent term lost 
during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product 
approval and only those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. Patent term extension 
may also be available in certain foreign countries upon regulatory approval of our product candidates. However, we may not be granted an extension because of, for 
example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. 
Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension or 
restoration or the term of any such extension is less than we request, the period during which we will have the right to exclusively market our product will be shortened 
and our competitors may 

80

 
 
 
 
 
 
 
 
obtain approval of competing products following our patent expiration, and our competitive position, business, financial condition, results of operations, and prospects 
could be harmed, possibly materially. 

If there are delays in obtaining regulatory approvals or other additional delays, the period of time during which we can market our product candidates under patent 
protection could be further reduced. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting 
such product candidates might expire before or shortly after such product candidates are commercialized. Once the patent term has expired, we may be open to 
competition from similar or generic products. The launch of a generic version of one of our products in particular would be likely to result in an immediate and 
substantial reduction in the demand for that product, which could have a material adverse effect on our business, financial condition, results of operations and prospects. 

Obtaining  and  maintaining  our  patent  protection  depends  on  compliance  with  various  procedural,  document  submission,  fee  payment  and  other  requirements 
imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements. 

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during 
the patent application process to maintain patent applications and issued patents. In addition, periodic maintenance fees, renewal fees, annuity fees and various other 
government fees on issued patents often must be paid to the USPTO and foreign patent agencies over the lifetime of the patent and/or applications and any patent rights 
we may obtain in the future. While an unintentional lapse of a patent or patent application can in many cases be cured by payment of a late fee or by other means in 
accordance  with  the  applicable  rules,  there  are  situations  in  which  noncompliance  with  these  requirements  can  result  in  abandonment  or  lapse  of  a  patent  or  patent 
application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent 
or  patent  application  include,  but  are  not  limited  to,  failure  to  respond  to  official  actions  within  prescribed  time  limits,  non-payment  of  fees  and  failure  to  properly 
legalize  and  submit  formal  documents.  If  we  fail  to  maintain  the  patents  and  patent  applications  covering  our  products  or  services,  we  may  not  be  able  to  stop  a 
competitor from marketing products or services that are the same as or similar to our products or services, which would have a material adverse effect on our business, 
financial condition and results of operations. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case. 

Our rights to develop and commercialize our product candidates are subject in part to the terms and conditions of licenses granted to us by others, and the patent 
protection, prosecution and enforcement for some of our product candidates may be dependent on our licensors. 

We currently are reliant upon licenses of certain intellectual property rights and proprietary technology from third parties that are important or necessary to the 
development of our proprietary technology, including technology related to our product candidates. For example, we rely on our exclusive license agreement with 
Novartis for the clinical development of darovasertib and our option and license agreement with CRT for the clinical development of PARG inhibitors. These licenses, 
and other licenses we may enter into in the future, may not provide adequate rights to use such intellectual property rights and proprietary technology in all relevant 
fields of use or in all territories in which we may wish to develop or commercialize technology and product candidates in the future. Licenses to additional third-party 
proprietary technology or intellectual property rights that may be required for our development programs may not be available in the future or may not be available on 
commercially reasonable terms. In that event, we may be required to expend significant time and resources to redesign our proprietary technology or product candidates 
or to develop or license replacement technology, which may not be feasible on a technical or commercial basis. If we are unable to do so, we may not be able to develop 
and commercialize technology and product candidates in fields of use and territories for which we are not granted rights pursuant to such licenses, which could harm 
our business, financial condition, results of operations and prospects significantly. Third-party patents may exist which might be enforced against our current or future 
product candidates, resulting in either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of 
compensation to third parties.

In some circumstances, we may not have the right to control the preparation, filing, prosecution and enforcement of patent applications, or to maintain the patents, 
covering technology that we license from third parties. In addition, some of our agreements with our licensors require us to obtain consent from the licensor before we 
can enforce patent rights, and our licensor may withhold such consent or may not provide it on a timely basis. Therefore, we cannot be certain that our licensors or 
collaborators will prosecute, maintain, enforce and defend such intellectual property rights in a manner consistent with the best interests of our business, including by 
taking reasonable measures to protect the confidentiality of know-how and trade secrets, or by paying all applicable prosecution and maintenance fees related to 
intellectual property registrations for any of our product candidates. We also cannot be certain that our licensors have drafted or prosecuted the patents and patent 

81

 
 
 
 
 
 
 
applications licensed to us in compliance with applicable laws and regulations, which may affect the validity and enforceability of such patents or any patents that may 
issue from such applications. This could cause us to lose rights in any applicable intellectual property that we in-license, and as a result our ability to develop and 
commercialize product candidates may be adversely affected and we may be unable to prevent competitors from making, using and selling competing products. 

Our current licenses impose, and our future licenses likely will impose, various royalty payments, milestones, and other obligations on us. If we fail to comply with any 
of these obligations, we may be subject to liability, including the payment of damages, and the licensor may have the right to terminate the license. Termination by the 
licensor would cause us to lose valuable rights, and could prevent us from developing and commercializing our product candidates and proprietary technologies. 
Furthermore, if any current or future licenses terminate, or if the underlying patents fail to provide the intended exclusivity, competitors or other third parties may gain 
the freedom to seek regulatory approval of, and to market, products similar or identical to our planned products. Moreover, our licensors may own or control intellectual 
property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the 
licensor’s rights. In addition, while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products, if any, 
the amounts may be significant. The amount of our future royalty obligations will depend on the technology and intellectual property we use in product candidates that 
we successfully develop and commercialize, if any. Therefore, even if we successfully develop and commercialize product candidates, we may be unable to achieve or 
maintain profitability. In addition, we may seek to obtain additional licenses from our licensors and, in connection with obtaining such licenses, we may agree to amend 
our existing licenses in a manner that may be more favorable to the licensors, including by agreeing to terms that could enable third parties (potentially including our 
competitors) to receive licenses to a portion of the intellectual property rights that are subject to our existing licenses. Any of these events could have a material adverse 
effect on our competitive position, business, financial conditions, results of operations, and prospects. 

We may fail to comply with any of our obligations under existing or future agreements pursuant to which we license or have otherwise acquired intellectual 
property rights or technology, which could result in the loss of rights or technology that are material to our business. 

We are party to various agreements that we depend on to operate our business, including intellectual property rights relating to darovasertib, in particular, our agreement 
with Novartis. Our rights to use currently licensed intellectual property, or intellectual property to be licensed in the future, are or will be subject to the continuation of 
and our compliance with the terms of these agreements. These agreements are complex, and certain provisions in such agreements may be susceptible to multiple 
interpretations which could lead to disputes, including but not limited to those regarding: 

•

•

•

•

•

•

•

•

•

the scope of rights granted under the license agreement; 

the extent to which our proprietary technology and product candidates infringe on intellectual property of the licensor that is not subject to the licensing 
agreement; 

the sublicensing of patent and other rights; 

diligence obligations under the license agreement and what activities satisfy those diligence obligations; 

the ownership of inventions and know-how resulting from the creation or use of intellectual property by us or our counterparties, alone or jointly; 

the scope and duration of our payment obligations; 

the priority of invention of patented technology;

rights upon termination of such agreement; and 

the scope and duration of exclusivity obligations of each party to the agreement. 

The resolution of any contractual interpretation dispute that may arise, if unfavorable to us, could have a material adverse effect on our business, financial condition, 
results of operations and prospects. Such resolution could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, 
increase what we believe to be our financial or other obligations under the relevant agreement or decrease the third-party’s financial or other obligations under the 
relevant agreement. 

Furthermore, if disputes over intellectual property rights that we have licensed or acquired from third parties prevent or impair our ability to maintain our current license 
agreements on acceptable terms, we may be unable to successfully develop 

82

 
 
 
 
 
 
and commercialize the affected product candidates. If we fail to comply with our obligations under current or future license agreements, these agreements may be 
terminated or the scope of our rights under them may be reduced and we might be unable to develop, manufacture or market any product that is licensed under these 
agreements. We are generally also subject to all of the same risks with respect to protection of intellectual property that we may license as we are for intellectual 
property that we own, which are described herein. If we or any of our current or future licensors fail to adequately protect this intellectual property, our ability to 
commercialize product candidates could suffer.

We may become subject to third-party claims alleging infringement, misappropriation or violation of such third-party’s patents or other intellectual property rights 
and/or third-party claims seeking to invalidate our patents, which could require us to spend significant time and money and, if successfully asserted against us, 
could delay or prevent us from developing, manufacturing and selling our products. 

Our commercial success depends significantly on our ability to develop, manufacture or commercialize our products and product candidates without infringing, 
misappropriating or otherwise violating the intellectual property rights of third parties. However, our research, development and commercialization activities may 
nonetheless be subject to claims that we infringe or otherwise violate patents or other intellectual property rights owned or controlled by third parties. Claims by third 
parties that we infringe their intellectual property rights may result in liability for damages or prevent or delay our developmental and commercialization efforts. We 
cannot assure you that our operations do not, or will not in the future, be found to infringe existing or future patents. 

Other entities may have or obtain patents or proprietary rights that could limit our ability to make, use, sell, offer for sale or import our product candidates or impair our 
competitive position. As the biotechnology industry expands and more patents are issued, the risk increases that our product candidates may be subject to claims of 
infringement of the patent rights of third parties. Our competitors in both the United States and abroad, many of which have substantially greater resources and have 
made substantial investments in patent portfolios and competing technologies, may have applied for or obtained or may in the future apply for and obtain, patents that 
will prevent, limit or otherwise interfere with our ability to make, use and sell our product candidates. There is a substantial amount of litigation, both within and 
outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement 
lawsuits, interferences, oppositions, reexaminations, inter partes review proceedings and post-grant review proceedings before the USPTO and/or corresponding 
foreign patent offices, and companies in the industry have used these proceedings to gain a competitive advantage. Numerous third-party U.S. and foreign issued 
patents and pending patent applications exist in the fields in which we are developing product candidates. There may be third-party patents or patent applications with 
claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. For example, we are 
aware of an international patent application published as PCT WO 2017/096165 A1. If a patent issues from such patent application with claims similar to those 
published, our ability to commercialize a product candidate for our MAT2A program may be adversely affected if we do not obtain a license under such patent. 

Furthermore, the scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history and can 
involve other factors such as expert opinion. Our analysis of these issues, including interpreting the relevance or the scope of claims in a patent or a pending application, 
determining applicability of such claims to our proprietary technologies or product candidates, predicting whether a third-party’s pending patent application will issue 
with claims of relevant scope, and determining the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect, which may 
negatively impact our ability to develop and market our product candidates. We do not always conduct independent reviews of pending patent applications of and 
patents issued to third parties. 

Additionally, patent applications in the United States and elsewhere are typically published approximately 18 months after the earliest filing for which priority is 
claimed, with such earliest filing date being commonly referred to as the priority date. Certain U.S. applications that will not be filed outside the United States can 
remain confidential until patents issue. In addition, patent applications in the United States and elsewhere can be pending for many years before issuance, or 
unintentionally abandoned patents or applications can be revived. Furthermore, pending patent applications that have been published can, subject to certain limitations, 
be later amended in a manner that could cover our technologies, our product candidates or the use of our product candidates. These applications may later result in 
issued patents, or the revival of previously abandoned patents, that will prevent, limit or otherwise interfere with our ability to make, use or sell our products. As a 
result, we may be unaware of third-party patents that may be infringed by commercialization of darovasertib, IDE397 or our other product candidates, and cannot be 
certain that we were the first to file a patent application related to a product candidate or proprietary technology. In addition, identification of third-party patent rights 
that may be relevant to our technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the 
difficulty in assessing the meaning of patent claims. Moreover, we may face patent infringement claims from non-practicing entities that have no relevant product 
revenue and against whom our own patent portfolio may thus have 

83

 
 
 
 
 
 
no deterrent effect. We may be unaware of one or more issued patents that would be infringed by the manufacture, sale or use of our product candidates.

Further, we may be required to indemnify future collaboration partners against claims of infringement, misappropriation, or other violations of intellectual property 
rights. We are not aware of any threatened or pending claims related to these matters, but in the future litigation may be necessary to defend against such claims. If a 
patent infringement suit were brought against us, we could be forced, including by court order to stop or delay development, manufacturing and/or sales of the product 
or product candidate that is the subject of the suit. As a result of patent infringement claims, or in order to avoid potential claims, we may choose to seek, or be required 
to seek, a license from the third-party and would most likely be required to pay license fees or royalties or both. These licenses may not be available on commercially 
reasonable terms, or at all, in which event our business would be materially and adversely affected. Even if we were able to obtain a license, we may be unable to 
maintain such licenses and the rights may be nonexclusive, which could give our competitors access to the same intellectual property.

Although no third-party has asserted a claim of patent infringement against us as of December 31, 2023, others may hold proprietary rights that could prevent 
darovasertib, IDE397, our other product candidates or any future product candidates from being marketed. Any patent-related legal action against us claiming damages 
and seeking to enjoin commercial activities relating to our product candidates or proprietary technologies could subject us to potential liability for damages, including 
treble damages if we were determined to willfully infringe or attorney’s fees and costs of litigation to the party whose intellectual property rights we may be found to be 
infringing, and require us to obtain a license to manufacture or market darovasertib, IDE397, our other product candidates or any future product candidates. Defense of 
these claims, regardless of their merit, would involve substantial litigation expense and would be time-consuming and a substantial diversion of management and 
employee resources from our business. Even if we believe such claims are without merit, we cannot predict whether we would prevail in any such actions or that any 
license required under any of these patents would be made available on commercially acceptable terms, if at all. Even if such licenses are available, we could incur 
substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our gross margins, and the rights may be non-
exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. In addition, we cannot be certain that we could 
redesign our product candidates or proprietary technologies to avoid infringement, if necessary, or on a cost-effective basis. If we were to challenge the validity of any 
such third-party U.S. patent in federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to present clear and 
convincing evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any 
such U.S. patent. We will have similar burdens to overcome in foreign courts in order to successfully challenge a third-party claim of patent infringement. Accordingly, 
an adverse determination in a judicial or administrative proceeding, or the failure to obtain necessary licenses, could prevent us from developing and commercializing 
darovasertib, our other product candidates or any future product candidates, until the asserted patent expires or is held finally invalid or not infringed in a court of law. 
In addition, intellectual property litigation, regardless of its outcome, may cause negative publicity or the disclosure of confidential information, and the perceived value 
of our product candidates or intellectual property could be diminished correspondingly. 

Additionally, our collaborators or any third parties with which we collaborate in the future, may not properly maintain or defend our intellectual property rights or may 
use our proprietary information in such a way as to invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us 
to litigation or potential liability. Further, collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential 
liability. Also, we may be obligated under our agreements with our collaborators, licensors, suppliers and others to indemnify and hold them harmless for damages 
arising from intellectual property infringement by us. Any of the foregoing could harm our competitive position, business, financial condition, results of operations, and 
prospects. 

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming, and unsuccessful. 
Further, our issued patents could be found invalid or unenforceable if challenged. 

Third parties, including our competitors may currently, or in the future, infringe, misappropriate or otherwise violate our issued patents or other intellectual property 
rights or those of our licensors. To prevent infringement or unauthorized use, we may be required to file lawsuits or initiate other proceedings to protect or enforce our 
patents or other intellectual property rights, which can be expensive, time-consuming and unsuccessful. However, the steps we have taken, and are taking, to protect our 
proprietary rights may not be adequate to enforce our rights as against such infringement, misappropriation or violation of our intellectual property rights. In certain 
circumstances it may not be practicable or cost-effective for us to enforce our intellectual property rights fully, particularly in certain developing countries or where the 
initiation of a claim might harm our business relationships. We may also be hindered or prevented from enforcing our rights with respect to a government entity or 
instrumentality because of the doctrine of sovereign immunity. Our ability to enforce our patent or other 

84

 
 
 
 
 
 
intellectual property rights depends on our ability to detect infringement. It may be difficult to detect infringers who do not advertise the components or methods that 
are used in connection with their products or technologies. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or potential 
competitor’s product or technologies. Thus, we may not be able to detect unauthorized use of, or take appropriate steps to enforce, our intellectual property rights. Any 
inability to meaningfully enforce our intellectual property rights could harm our ability to compete and reduce demand for our products and product candidates.

In addition, in a patent infringement proceeding, a court or administrative tribunal may decide that a patent we own or in-license is not valid, is unenforceable and/or is 
not infringed. If we or any of our collaborators or potential future collaborators, were to initiate legal proceedings against a third-party to enforce a patent directed at 
one of our product candidates, the defendant could counterclaim that our patent is invalid and/or unenforceable in whole or in part. In patent litigation in the United 
States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge include an alleged failure to meet any of 
several statutory requirements, including lack of novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could include an allegation that 
someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution. Third parties 
may also raise similar claims before the USPTO, even outside the context of litigation. Similar mechanisms for challenging the validity and enforceability of a patent 
exist in foreign patent agencies. The outcome following legal assertions of invalidity and unenforceability is unpredictable, and could result in the revocation, 
cancellation, or amendment of our patents or those of our licensors. With respect to validity, for example, we cannot be certain that there is no invalidating prior art, of 
which we and the patent examiner were unaware during prosecution. A court may decide that a patent or other intellectual property right of ours is invalid or 
unenforceable, in whole or in part, construe the patent’s claims or other intellectual property narrowly or refuse to stop the other party from using the technology at 
issue on the grounds that our patents or other intellectual property do not cover the technology in question. If a defendant were to prevail on a legal assertion of 
invalidity and/or unenforceability, we could lose at least part, and perhaps all, of the patent protection on an affected product candidate. Such a loss of patent protection 
would have a material adverse impact on our business, financial condition, results of operations and prospects. 

Additionally, interference or derivation proceedings provoked by third parties or brought by us or declared by the USPTO, or equivalent actions brought in foreign 
jurisdictions, may be necessary to determine the priority of invention with respect to our patents or patent applications or those of our licensors. Our defense of 
litigation or interference proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. An unfavorable 
outcome could require us to cease using the covered technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the 
prevailing party does not offer us a license on commercially reasonable terms or at all, or if a non-exclusive license is offered and our competitors gain access to the 
same technology. These and other uncertainties associated with litigation could have a material adverse effect on our ability to raise the funds necessary to continue our 
clinical trials, continue our research programs, license necessary technology from third parties or enter into development or manufacturing partnerships that would help 
us bring our product candidates to market. 

Even if resolved in our favor, litigation or other legal proceedings relating to our intellectual property rights may cause us to incur significant expenses, and could 
distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions 
or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the 
price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development 
activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings 
adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial 
resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the 
marketplace. 

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential 
information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other 
interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our 
common stock. Any of the foregoing could harm our business, financial condition, results of operations and prospects. Even if our patents or other intellectual property 
rights are found to be valid and infringed, a court may refuse to grant injunctive relief against the infringer and instead grant us monetary damages and/or ongoing 
royalties. Such monetary compensation may be insufficient to adequately offset the damage to our business caused by the infringer’s competition in the market. An 
adverse result in any litigation or administrative proceeding could put one or more of our patents or other intellectual 

85

 
 
 
 
 
property rights at risk of being invalidated or interpreted narrowly, which could adversely affect our competitive business position, financial condition and results of 
operations.

We may be subject to claims that we or our employees, consultants, advisors or other third parties have wrongfully used or disclosed alleged confidential 
information or trade secrets of their former employers. 

We may be subject to claims that our employees or consultants have wrongfully used for our benefit or disclosed to us confidential information of third parties. As is 
common in the biotechnology and biopharmaceutical industries, in addition to our employees, we engage the services of consultants, advisors and other third parties to 
assist us in the development of our product candidates. Many of these individuals, and many of our employees, were previously employed at, or may have previously 
provided or may be currently providing consulting services to, other biotechnology or biopharmaceutical companies including our competitors or potential competitors. 
Some of these employees, consultants and contractors, may have executed proprietary rights, non-disclosure and non-competition agreements in connection with such 
previous employment or engagement. Although we try to ensure that individuals working for or collaborating with us do not use the intellectual property rights, 
proprietary information or know-how of others in their work for us, and do not perform work for us that is in conflict with their obligations to another employer or any 
other entity, we may become subject to claims that we, our employees, consultants, advisors or other third parties have, inadvertently or otherwise, misappropriated the 
intellectual property, including know-how, trade secrets or other information proprietary to their former or current employers or clients. We may also be subject to 
claims that patents and applications we have filed to protect inventions of our employees, consultants, advisors or other third parties, even those related to one or more 
of our product candidates, are rightfully owned by their former or concurrent employer. Litigation may be necessary to defend against these claims. There is no 
guarantee of success in defending these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual 
property rights, which could adversely affect our competitive position, business, financial condition, results of operations, and prospects. Even if we are successful in 
defending against these claims, litigation could result in substantial costs and be a distraction to our management team.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property rights. 

We may also be subject to claims that our former employees, contractors or collaborators, or other third parties have an ownership interest in our current or future 
patents, patent applications, or other intellectual property rights, including as an inventor or co-inventor. We may be subject to ownership or inventorship disputes in the 
future arising, for example, from conflicting obligations of employees, consultants or others who were or are involved in developing our products or product candidates. 
Although it is our policy to require our employees and our personnel who may be involved in the development of intellectual property to execute agreements assigning 
such inventions, we may not obtain these agreements in all circumstances, and individuals with whom we have these agreements may not comply with their terms. The 
assignment of intellectual property may not be self-executing and despite such agreement, such inventions may become assigned to third parties. In the event of 
unauthorized use or disclosure of our trade secrets or proprietary information, these agreements, even if obtained, may not provide meaningful protection, particularly 
for our trade secrets or other confidential information. We may be subject to claims that former employees, consultants, advisors or other third parties have an 
ownership interest in our patents or other intellectual property. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable 
intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property rights, and other owners may be able to license their rights to 
other third parties, including our competitors. Such an outcome could have a material adverse effect on our business. Even if we are successful in prosecuting or 
defending against such claims, litigation could result in substantial costs and be a distraction to our management and scientific personnel.

In addition, we may face claims by third parties challenging ownership interest in or inventorship of intellectual property rights we regard as our own, based on claims 
that our agreements with employees, consultants, advisors or other third parties obligating them to assign intellectual property to us are ineffective or in conflict with 
prior or competing contractual obligations of assignment, which could result in ownership disputes regarding intellectual property we have developed or will develop 
and interfere with our ability to capture the commercial value of such intellectual property. We are not aware of any threatened or pending claims related to these 
matters, but in the future litigation may be necessary to defend against these and other claims challenging inventorship or ownership and it may be necessary or we may 
desire to obtain a license to such third-party’s intellectual property rights to settle any such claim; however, there can be no assurance that we would be able to obtain 
such license on commercially reasonable terms, if at all. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable 
intellectual property rights. A court could prohibit us from using technologies, features or other intellectual property rights that are essential to our products or 
technologies, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of another person or entity, 
including another or former employers. An inability to incorporate technologies, features or other intellectual property rights 

86

 
 
 
 
 
 
that are important or essential to our products or product candidates could have a material adverse effect on our business, financial condition, results of operations, and 
competitive position, and may prevent us from developing, manufacturing and/or commercializing our products or technologies. In addition, we may lose valuable 
intellectual property rights or personnel. Such an outcome could have a material adverse effect on our competitive position, business, financial condition, results of 
operations, and prospects. Even if we are successful in defending against such claims, litigation could result in substantial costs and distraction to management and 
other employees. Any litigation or the threat thereof may adversely affect our ability to hire employees or contract with independent sales representatives. A loss of key 
personnel or their work product could hamper or prevent our ability to develop, manufacture and/or commercialize our products or services, which could materially and 
adversely affect our business, financial condition and results of operations.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. 

In addition to patent protection, we also rely on other intellectual property rights, including protection of copyright, trade secrets, know-how, technology and/or other 
proprietary information that is not patentable or that we elect not to patent. Trade secrets can be difficult to protect, and some courts are less willing or unwilling to 
protect trade secrets. To maintain the confidentiality of our trade secrets and proprietary information, we rely heavily on confidentiality agreements with third parties, 
and confidential information and invention assignment agreements with employees, consultants, advisors and appropriate third parties. However, we cannot guarantee 
that we have entered into such agreements with each party that may have or have had access to our trade secrets or proprietary technology and processes and we may 
not enter into such agreements with all employees, consultants and third parties who have been involved in the development of our intellectual property rights. 
Although we generally require all of our employees, consultants, advisors and any third parties who have access to our proprietary know-how, information, or 
technology to enter into confidentiality agreements, we cannot provide any assurances that all such agreements have been duly executed. 

In addition to contractual measures, we try to protect the confidential nature of our proprietary information using commonly accepted physical and technological 
security measures. Despite these efforts, we cannot provide any assurances that all such agreements have been duly executed, and any of these parties may breach the 
agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. In addition, 
such security measures may not provide adequate protection for our proprietary information, for example, in the case of misappropriation of a trade secret by an 
employee, consultant, customer or third-party with authorized access. Our security measures may not prevent an employee, consultant, advisor or other third-party from 
misappropriating our trade secrets and providing them to a competitor, and recourse we take against such misconduct may not provide an adequate remedy to protect 
our interests fully. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary 
technologies will be effective. Therefore, we may not be able to prevent the unauthorized disclosure or use of our technical knowledge or other trade secrets by such 
employees, consultants, advisors or third parties, despite the existence generally of these confidentiality restrictions. These agreements may not provide meaningful 
protection against the unauthorized use or disclosure of our trade secrets, know-how or other proprietary information in the event the unwanted use is outside the scope 
of the provisions of the contracts or in the event of any unauthorized use, misappropriation, or disclosure of such trade secrets, know-how, or other proprietary 
information. There can be no assurances that such employees, consultants, advisors or third parties will not breach their agreements with us, that we will have adequate 
remedies for any breach, or that our trade secrets will not otherwise become known or independently developed by third parties, including our competitors.

Unauthorized parties may also attempt to copy or reverse engineer certain aspects of our products that we consider proprietary. We may not be able to obtain adequate 
remedies in the event of such unauthorized use. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-
consuming, and the outcome is unpredictable. Further, we may not be able to obtain adequate remedies for any breach. Even though we use commonly accepted 
security measures, trade secret violations are often a matter of state law in the United States, and the criteria for protection of trade secrets can vary among different 
jurisdictions. If the steps we have taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for 
misappropriating the trade secret. 

Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. 
Because from time to time we expect to rely on third parties in the development, manufacture, and distribution of our products and provision of our services, we must, 
at times, share trade secrets with them. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. Trade secrets 
will over time be disseminated within the industry through independent development, the publication of journal articles and the movement of personnel skilled in the art 
from company to company or academic to industry scientific positions. Though our agreements with third parties typically restrict the ability of our advisors, 
employees, collaborators, licensors, suppliers, third-party contractors and consultants to publish data potentially relating to our trade secrets, our 

87

 
 
 
 
 
 
agreements may contain certain limited publication rights. In addition, if any of our trade secrets were to be lawfully obtained or independently developed by a 
competitor, we would have no right to prevent such competitor from using that technology or information to compete with us, which could harm our competitive 
position. Despite employing the contractual and other security precautions described above, the need to share trade secrets increases the risk that such trade secrets 
become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. If any of these 
events occurs or if we otherwise lose protection for our trade secrets, the value of this information may be greatly reduced and our competitive position, business, 
financial condition, results of operations, and prospects would be harmed. If any of our trade secrets were to be disclosed to or independently developed by a 
competitor, our competitive position would be harmed. The exposure of our trade secrets and other proprietary information would impair our competitive advantages 
and could have a material adverse effect on our business, financial condition and results of operations. In particular, a failure to protect our proprietary rights may allow 
competitors to copy our technology, which could adversely affect our pricing and market share. If we do not apply for patent protection prior to such publication or if 
we cannot otherwise maintain the confidentiality of our proprietary technology and other confidential information, then our ability to obtain patent protection or to 
protect our trade secret information may be jeopardized. 

Intellectual property rights do not necessarily address all potential threats to our competitive advantage. 

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately 
protect our business or permit us to maintain our competitive advantage. For example: 

•

•

•

•

•

•

•

•

•

•

others may be able to make precision medicines that are similar to ours but that are not covered by the claims of the patents that we own or have 
exclusively licensed; 

we or our licensors or future collaborators might not have been the first to make the inventions covered by the issued patents or pending patent 
applications that we own or have exclusively licensed; 

we or our licensors or future collaborators might not have been the first to file patent applications covering certain of our inventions; 

others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual property 
rights; 

it is possible that our pending patent applications or those that we may own in the future will not lead to issued patents;

issued patents that we hold rights to may be held invalid or unenforceable, including as a result of legal challenges by our competitors;

the patents of others may harm our business;

we may choose not to seek patent protection for some of our proprietary technology to maintain certain trade secrets or know-how, and a third-party may 
subsequently file a patent covering such trade secrets or know-how;

our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned 
from such activities to develop competitive products for sale in our major commercial markets; and 

we may not develop additional proprietary technologies that are patentable; 

Should any of these events occur, they could significantly harm our business, financial condition, results of operations and prospects. 

Risks Related to Government Regulation 

Enacted and future healthcare legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates 
and may affect the prices we may set. 

In the United States, the EU and other jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes and 
proposed changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue to be a number of initiatives at 
the U.S. federal and state levels that seek to reduce healthcare costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and 
Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the ACA, was 

88

 
 
 
 
 
 
 
enacted, which substantially changed the way healthcare is financed by both governmental and private payors. Among the provisions of the ACA, those of greatest 
importance to the pharmaceutical and biotechnology industries include the following: 

•

•

•

•

•

•

•

an annual, non-deductible fee payable by any entity that manufactures or imports certain branded prescription drugs and biologic agents (other than 
those designated as orphan drugs), which is apportioned among these entities according to their market share in certain government healthcare programs; 

an increase to the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and an extension the rebate program to 
individuals enrolled in Medicaid managed care organizations; 

a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, 
infused, instilled, implanted or injected;

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to certain individuals with 
income at or below 133% of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability; 

a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of 
applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered 
under Medicare Part D; 

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along 
with funding for such research; and 

establishment of a Center for Medicare and Medicaid Innovation at the Centers for Medicare & Medicaid Services, or CMS, to test innovative payment 
and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending. 

Since its enactment, there have been judicial, executive and congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court 
dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the U.S. 
Supreme Court’s decision, President Biden issued an executive order initiating a special enrollment period from February 15, 2021 through August 15, 2021 for 
purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and 
reconsider their existing policies and rules that limit access to healthcare.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. In August 2011, the Budget Control Act of 
2011, among other things, led to aggregate reductions of Medicare payments to providers. These reductions went into effect in April 2013 and, due to subsequent 
legislative amendments to the statute, will remain in effect through 2032, with the exception of a temporary suspension from May 1, 2020 through March 31, 2022, 
unless additional action is taken by Congress. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further 
reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations 
period for the government to recover overpayments to providers from three to five years. 

The American Rescue Plan Act of 2021 was also signed into law, which eliminates the statutory Medicaid drug rebate cap, beginning January 1, 2024. The rebate was 
previously capped at 100% of a drug’s average manufacturer price.

Moreover, on August 16, 2022, the Inflation Reduction Act of 2022, or IRA, was signed into law, which among other things, includes prescription drug provisions that 
have significant implications for the pharmaceutical industry and beneficiaries, including extending enhanced subsidies for individuals purchasing health insurance 
coverage in ACA marketplaces through plan year 2025, allowing the federal government to negotiate a maximum fair price for certain high-priced single source 
Medicare drugs, imposing penalties and excise tax for manufacturers that fail to comply with the drug price negotiation requirements, requiring inflation rebates for all 
Medicare Part B and Part D drugs, with limited exceptions, if their drug prices increase faster than inflation, and redesigning Medicare Part D to reduce out-of-pocket 
prescription drug costs for beneficiaries. On August 29, 2023, HHS announced the list of the first ten drugs that will be subject to price negotiations, although the drug 
price negotiation program is currently subject to legal challenges. For that and other reasons, it is currently unclear how the IRA will be effectuated. The 
implementation of cost containment measures, including the prescription drug provisions under the IRA, as well as other healthcare reforms may prevent us from being 
able to generate revenue, attain profitability, or commercialize our product candidates if approved. Complying with any new legislation and regulatory changes could be 
time-intensive and expensive, resulting in a material adverse effect on our business. 

89

 
 
 
 
 
Individual states in the United States have also increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product 
pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, 
and, in some cases, designed to encourage importation from other countries and bulk purchasing. Legally-mandated price controls on payment amounts by third-party 
payors or other restrictions could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual 
hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other 
healthcare programs. Furthermore, there has been increased interest by third-party payors and governmental authorities in reference pricing systems and publication of 
discounts and list prices. These reforms could reduce the ultimate demand for our product candidates or put pressure on our product pricing. 

In the EU, similar political, economic and regulatory developments may affect our ability to profitably commercialize our product candidates, if approved. In addition 
to continuing pressure on prices and cost containment measures, legislative developments at the EU or member state level may result in significant additional 
requirements or obstacles that may increase our operating costs. The delivery of healthcare in the EU, including the establishment and operation of health services and 
the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than EU, law and policy. National governments and health service 
providers have different priorities and approaches to the delivery of health care and the pricing and reimbursement of products in that context. In general, however, the 
healthcare budgetary constraints in most EU member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service 
providers. Coupled with ever-increasing EU and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing 
approval of our product candidates, restrict or regulate post-approval activities and affect our ability to commercialize our product candidates, if approved. In markets 
outside of the United States and European Union, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted 
price ceilings on specific products and therapies. 

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action in the United States, the EU 
or any other jurisdiction. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements 
or policies, or if we or such third parties are not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been 
obtained and we may not achieve or sustain profitability. 

Our business operations and current and future relationships with investigators, healthcare professionals, consultants, third-party payors, patient organizations 
and customers will be subject to applicable healthcare regulatory laws, which could expose us to penalties. 

Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, patient organizations and 
customers, may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations. These laws may constrain the business or financial 
arrangements and relationships through which we conduct our operations, including how we research, market, sell and distribute our product candidates, if approved. 
Such laws include: 

•

•

the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering, 
receiving or providing any remuneration (including any kickback, bribe, or certain rebate), directly or indirectly, overtly or covertly, in cash or in kind, to 
induce or reward, or in return for, either the referral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or 
service, for which payment may be made, in whole or in part, under any U.S. federal healthcare program, such as Medicare and Medicaid. A person or 
entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation; 

the U.S. federal civil and criminal false claims and civil monetary penalties laws, including the civil False Claims Act, which prohibit, among other 
things, including through civil whistleblower or qui tam actions, individuals or entities from knowingly presenting, or causing to be presented, to the 
U.S. federal government, claims for payment or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a false 
record or statement material to a false or fraudulent claim, or from knowingly making a false statement to avoid, decrease or conceal an obligation to pay 
money to the U.S. federal government. Pharmaceutical manufacturers can cause false claims to be presented to the U.S. federal government by engaging 
in impermissible marketing practices, such as the off-label promotion of a product for an indication for which it has not received FDA approval. In 
addition, the government may assert that a claim including items and services resulting from a 

90

 
 
 
 
 
 
•

•

•

•

•

•

•

violation of the U.S. federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act; 

the Health Insurance Portability and Accountability Act, as amended by the Health Information Technology for Economic and Clinical Health Act of 
2009, or HIPAA, which imposes criminal and civil liability for, among other things, knowingly and willfully executing, or attempting to execute, a 
scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any 
materially false statement, in connection with the delivery of, or payment for, healthcare benefits, items or services. Similar to the U.S. federal Anti-
Kickback Statute, a person or entity does not need to have actual knowledge of the healthcare fraud statute implemented under HIPAA or specific intent 
to violate it in order to have committed a violation; 

the Federal Food Drug or Cosmetic Act, or FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics and medical 
devices; 

the U.S. Physician Payments Sunshine Act and its implementing regulations, which requires certain manufacturers of drugs, devices, biologics and 
medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, to report 
annually to the government information related to certain payments and other transfers of value to physicians (defined to include doctors, dentists, 
optometrists, podiatrists and chiropractors), certain non-physician practitioners (nurse practitioners, certified nurse anesthetists, physician assistants, 
clinical nurse specialists, anesthesiology assistants and certified nurse midwives), and teaching hospitals, as well as ownership and investment interests 
held by the physicians described above and their immediate family members; 

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers; 

analogous U.S. state laws and regulations, including: state anti-kickback and false claims laws, which may apply to our business practices, including but 
not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare items or services reimbursed by any third-party 
payor, including private insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance 
guidelines and the relevant compliance guidance promulgated by the U.S. federal government, or otherwise restrict payments that may be made to 
healthcare providers and other potential referral sources; and state laws and regulations that require drug manufacturers to file reports relating to pricing 
and marketing information, which requires tracking gifts and other remuneration and items of value provided to healthcare professionals and entities; 
state and local laws requiring the registration of pharmaceutical sales representatives; 

the U.S. Foreign Corrupt Practices Act of 1977, as amended, which prohibits, among other things, U.S. companies and their employees and agents from 
authorizing, promising, offering, or providing, directly or indirectly, corrupt or improper payments or anything else of value to foreign government 
officials, employees of public international organizations and foreign government owned or affiliated entities, candidates for foreign political office, and 
foreign political parties or officials thereof; and 

similar healthcare laws and regulations in the EU and other jurisdictions, including reporting requirements detailing interactions with and payments to 
healthcare providers. 

Ensuring that our internal operations and future business arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial 
costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or 
case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above 
or any other governmental laws and regulations that may apply to us, we may be subject to significant penalties, including civil, criminal and administrative penalties, 
damages, fines, exclusion from government-funded healthcare programs, such as Medicare and Medicaid or similar programs in other countries or jurisdictions, 
integrity oversight and reporting obligations to resolve allegations of non-compliance, disgorgement, individual imprisonment, contractual damages, reputational harm, 
diminished profits and the curtailment or restructuring of our operations. If any of the physicians or other providers or entities with whom we expect to do business are 
found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded 
healthcare programs and imprisonment, which could affect our ability to operate our business. Further, defending against any such actions can be costly, time-
consuming and may require significant personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, 
our business may be impaired. 

91

 
 
 
Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely 
affect our business, results of operations, and financial condition.

The regulatory environment surrounding information security, data collection and privacy is increasingly demanding. We are subject to numerous U.S. federal and state 
laws and non-U.S. regulations governing the protection of personal and confidential information of our clinical patients, clinical investigators, employees and 
vendors/business contacts, including in relation to medical records, credit card data and financial information. Outside the United States, an increasing number of laws, 
regulations, and industry standards apply to data privacy and security. For example, in Europe, European Union General Data Protection Regulation, or GDPR, went 
into effect in May 2018, implementing more stringent requirements in relation to our use of personal data. The GDPR applies to any company established in the 
European Economic Area, or EEA, as well as to those outside the EEA if they collect and use personal data in connection with the offering of goods or services to 
individuals in the EEA or the monitoring of their behavior. Companies that must comply with the GDPR face increased compliance obligations and risk, including more 
robust regulatory enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues of the 
noncompliant company, whichever is greater. Among other requirements, the GDPR regulates transfers of personal data subject to the GDPR to third countries that 
have not been found to provide adequate protection to such personal data, including the U.S., and the efficacy and longevity of current transfer mechanisms between the 
EU and the U.S. remains uncertain, and the efficacy and longevity of current transfer mechanisms between the EEA, and the United States remains uncertain. Case law 
from the Court of Justice of the European Union, or CJEU, states that reliance on the standard contractual clauses - a standard form of contract approved by the 
European Commission as an adequate personal data transfer mechanism - alone may not necessarily be sufficient in all circumstances and that transfers must be 
assessed on a case-by-case basis. On October 7, 2022, President Biden signed an Executive Order on ‘Enhancing Safeguards for United States Intelligence Activities’ 
which introduced new redress mechanisms and binding safeguards to address the concerns raised by the CJEU in relation to data transfers from the EEA to the United 
States and which formed the basis of the new EU-US Data Privacy Framework, or DPF, as released on December 13, 2022. The European Commission adopted its 
Adequacy Decision in relation to the DPF on July 10, 2023, rendering the DPF effective as a GDPR transfer mechanism to U.S. entities self-certified under the DPF. 
The DPF also introduced a new redress mechanism for EU citizens which addresses a key concern in the previous CJEU judgments and may mean transfers under 
standard contractual clauses are less likely to be challenged in future. We currently rely on the EU standard contractual clauses and the UK Addendum to the EU 
standard contractual clauses, as relevant, to transfer personal data outside the EEA and the UK, including to the United States, with respect to both intragroup and third 
party transfers. We expect the existing legal complexity and uncertainty regarding international personal data transfers to continue. In particular, we expect the DPF 
Adequacy Decision to be challenged and international transfers to the United States and to other jurisdictions more generally to continue to be subject to enhanced 
scrutiny by regulators. As a result, we may have to make certain operational changes and we will have to implement revised standard contractual clauses and other 
relevant documentation for existing data transfers within required time frames.

Further, from January 1, 2021, companies have had to comply with the GDPR and also the UK data protection regime, which imposes separate but similar obligations 
to those under the GDPR. The UK GDPR mirrors the fines under the GDPR (e.g., fines up to the greater of €20 million (£17.5 million) or 4% of global turnover). On 
October 12, 2023, the UK Extension to the DPF came into effect (as approved by the UK Government), as a UK GDPR data transfer mechanism to U.S. entities self-
certified under the UK Extension to the DPF. As we continue to expand into other foreign countries and jurisdictions, we may be subject to additional laws and 
regulations that may affect how we conduct business.

In the United States, HIPAA imposes privacy, security and breach reporting obligations with respect to individually identifiable health information upon “covered 
entities” (health plans, health care clearinghouses and certain health care providers), and their respective business associates, individuals or entities that create, receive, 
maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. While we do not believe that we are 
currently acting as a covered entity or business associate under HIPAA and thus are not directly regulated under HIPAA, any person may be prosecuted under HIPAA’s 
criminal provisions either directly or under aiding-and-abetting or conspiracy principles. Consequently, depending on the facts and circumstances, we could face 
substantial criminal penalties if we knowingly receive individually identifiable health information from a HIPAA-covered healthcare provider or research institution 
that has not satisfied HIPAA’s requirements for disclosure of individually identifiable health information. 

In addition, certain states govern the privacy and security of health-related and other personal information in certain circumstances, many of which differ from each 
other in significant ways and may not have the same effect, thus complicating compliance efforts. By way of example, the California Consumer Privacy Act, or CCPA, 
went into effect on January 1, 2020, and imposes increased privacy and security obligations on entities handling certain personal information of consumers or 
households, and gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing, and receive 
detailed information about how their personal information is used. The CCPA 

92

 
 
 
 
 
provides for civil penalties for violations, as well as a private right of action for data breaches that has increased the likelihood of, and risks associated with data breach 
litigation. The CCPA may increase our compliance costs and potential liability. Further, the California Privacy Rights Act, or CPRA, generally went into effect on 
January 1, 2023, and significantly amends the CCPA. It imposes additional data protection obligations on covered companies doing business in California, including 
additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It also created 
a new California data protection agency specifically tasked to enforce the law, which would likely result in increased regulatory scrutiny of California businesses in the 
areas of data protection and security. Additional compliance investment and potential business process changes may also be required. Similar laws have passed in other 
states and are continuing to be proposed at the state and federal level, reflecting a trend toward more stringent privacy legislation in the United States. The enactment of 
such laws could have potentially conflicting requirements that would make compliance challenging. In the event that we are subject to or affected by HIPAA, the 
CCPA, the CPRA or other domestic privacy and data protection laws, any liability from failure to comply with the requirements of these laws could adversely affect our 
financial condition.

If any person, including any of our employees, clinical trial collaborators or those with whom we share such information, negligently disregards or intentionally 
breaches our established controls with respect to clinical subject, clinical investigator or employee data, or otherwise mismanages or misappropriates that data, we could 
be subject to significant monetary damages, regulatory enforcement actions, fines and/or criminal prosecution in one or more jurisdictions. In addition, a data breach 
could result in negative publicity which could damage our reputation and have an adverse effect on our business, financial condition or results of operations.

pandemic, as well as adverse geopolitical and macroeconomic developments, such as the ongoing Ukraine-Russia conflict, the Israel-Hamas conflict, 
and related sanctions, instability in the global banking system, actual and anticipated changes in interest rates, economic inflation and the responses by 
central banking authorities to control such inflation; and 

general economic and geo-political conditions in the United States and abroad. 

In addition, the stock markets in general, and the markets for biopharmaceutical and biotechnology stocks in particular, have experienced extreme volatility. In 
particular, the market prices of securities of smaller biotechnology have experienced dramatic fluctuations that often have been unrelated or disproportionate to the 
operating results of these companies. These broad market fluctuations may adversely affect the trading price or liquidity of our common stock. Furthermore, the trading 
price of our common stock may be adversely affected by third-parties trying to drive down the market price. Short sellers and others, some of whom post anonymously 
on social media, may be positioned to profit if our stock declines and their activities can negatively affect our stock price. In the past, when the market price of a stock 
has been volatile, holders of that stock have sometimes instituted securities class action litigation against the issuer. If any of our stockholders were to bring such a 
lawsuit against us, we could incur substantial costs defending the lawsuit and the attention of our management would be diverted from the operation of our business. 

An active, liquid and orderly market for our common stock may not be maintained, and you may not be able to resell your common stock. 

Prior to our initial public offering, or IPO, in May 2019, there was no public market for shares of our common stock. Our stock currently trades on the Nasdaq Global 
Select Market, but we can provide no assurance that we will be able to maintain an active trading market on the Nasdaq Global Select Market or any other exchange in 
the future. The lack of an active market may impair your ability to sell your shares at the time you wish to sell them or at a price that you consider reasonable. An 
inactive market may also impair our ability to raise capital by selling shares and may impair our ability to acquire other businesses, applications, or technologies using 
our shares as consideration. 

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall. 

If our existing stockholders sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the trading price of our common stock 
could decline. As of December 31, 2023, we have outstanding a total of 65.0 million shares of common stock, of which the holders of approximately 2.3 million shares 
of our common stock are entitled to rights with respect to the registration of their shares under the Securities Act. Registration of these shares under the Securities Act 
would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares purchased by affiliates. Any sales of securities by 
these stockholders could have a material adverse effect on the trading price of our common stock. In addition, as of December 31, 2023, approximately 11.4 million 
shares of common stock that are either subject to outstanding options or reserved for future issuance under our existing equity incentive plan will become eligible for 
sale in the public market to the extent permitted by the provisions of various vesting schedules, Rule 144 and Rule 701 under the Securities Act. If these additional 
shares of common stock are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline.

General Risks 

Our information technology systems, or those of our collaborators, CROs or other contractors or consultants, may fail or suffer security breaches, which could 
adversely affect our business. Security breaches, loss of data or financial assets, and other disruptions could compromise sensitive information related to our 
business or prevent us from accessing critical information and expose us to liability. 

We collect and maintain information in digital form that is necessary to conduct our business, and we are increasingly dependent on information technology systems 
and infrastructure to operate our business. In the ordinary course of our business, we collect, store and transmit large amounts of confidential information, including 
intellectual property, proprietary 

94

 
 
 
 
 
 
 
 
 
business information, preclinical and clinical trial data, health-related information and personal information, or collectively, Confidential Information. It is critical that 
we do so in a secure manner to maintain the confidentiality and integrity of such Confidential Information, including both our own and that of third parties. We have 
established physical, electronic and organizational measures to safeguard and secure our systems to prevent a data compromise, and rely on commercially available 
systems, software, tools, and monitoring to provide security for our information technology systems and the processing, transmission and storage of digital information. 
We have also outsourced elements of our information technology infrastructure, and as a result a number of third-party vendors may or could have access to our 
Confidential Information. Our internal information technology systems and infrastructure, and those of our current and any future collaborators, contractors and 
consultants and other third parties on which we rely, are vulnerable to attack, damage and interruption from computer viruses, malware (e.g. ransomware), malicious 
code, misconfigurations, “bugs” or other vulnerabilities, natural disasters, terrorism, war, telecommunication and electrical failures, hacking, cyberattacks or intrusions 
over the Internet, phishing attacks and other social engineering schemes, attachments to emails, human error, fraud, denial or degradation of service attacks, 
sophisticated nation-state and nation-state-supported actors, employee theft or misuse, persons inside our organization, or persons with access to systems inside our 
organization. 

The risk of a security breach or disruption or data loss, particularly through cyberattacks or cyber-intrusion, including by computer hackers, foreign governments and 
cyber-terrorists, has generally increased as the number, level of persistence, intensity and sophistication of attempted attacks and intrusions from around the world have 
increased. Emerging and evolving cybersecurity threats such as the attack on SolarWinds and the Log4j vulnerability reported in December 2021 pose unique 
challenges and involve sophisticated threat actors. In addition, the pervasive use of mobile devices that access Confidential Information increases the risk of data 
security breaches, which could lead to the loss of Confidential Information, including both our own and that of third parties. As a result of the continuing hybrid 
working environment, we may also face increased cybersecurity risks due to our reliance on internet technology and the number of our employees who are working 
remotely, which may create additional opportunities for cybercriminals to exploit vulnerabilities.

We rely on industry-accepted security measures and technology to securely maintain all confidential and proprietary information on our information systems. We have 
devoted and will continue to devote significant resources to the security of our information technology systems, but they may still be vulnerable to these threats. 
Furthermore, because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not recognized until launched 
against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. We may also experience security breaches that may 
remain undetected for an extended period. The costs to us to mitigate network security problems, bugs, viruses, worms, malicious software programs and security 
vulnerabilities could be significant, and while we have implemented security measures to protect our data security and information technology systems, our efforts to 
address these problems may not be successful, and these problems could result in unexpected interruptions, delays, cessation of service and other harm to our business 
and our competitive position. There can also be no assurance that our programs, and our future collaborators’, contractors’ and consultants’ cybersecurity risk 
management programs and processes, including policies, controls or procedures, will be fully implemented, complied with or effective in protecting our systems, 
networks and Confidential Information.

We and certain of our service providers are from time to time subject to cyberattacks and security incidents. While we do not believe that we have experienced any 
significant system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material 
disruption of our product development programs. For example, the loss of clinical trial data could result in delays in our regulatory approval efforts and significantly 
increase our costs to recover or reproduce the data. Moreover, if a computer security breach affects our systems or results in the unauthorized release of personally 
identifiable information, our reputation could be materially damaged. In addition, such a breach may require notification to governmental agencies, the media or 
individuals pursuant to applicable privacy and security laws. We would also be exposed to a risk of loss, including financial assets, litigation and potential liability and  
significant incident response, system restoration or remediation and future compliance costs, all of which could materially adversely affect our business, financial 
condition, results of operations and prospects. We maintain cyber liability insurance; however, this insurance may not be sufficient to cover the financial, legal, business 
or reputational losses that may result from an interruption or breach of our systems.

If we engage in future acquisitions or strategic collaborations, it may increase our capital requirements, dilute our stockholders, cause us to incur debt or assume 
contingent liabilities and subject us to other risks. 

We may evaluate various acquisitions and strategic collaborations, including licensing or acquiring complementary products, intellectual property rights, technologies, 
or businesses. Any potential acquisition or strategic partnership may entail numerous risks, including: 

95

 
 
 
 
 
 
•

•

•

•

•

•

•

•

increased operating expenses and cash requirements; 

the assumption or incurrence of additional indebtedness or contingent liabilities; 

the issuance of our equity securities; 

assimilation of operations, intellectual property and products of an acquired company, including difficulties associated with integrating new personnel; 

the diversion of our management’s attention from our existing product programs and initiatives in pursuing such a strategic merger or acquisition; 

loss of key personnel, and uncertainties in our ability to maintain key business relationships; 

uncertainties associated with the other party to such a transaction, including the prospects of that party and their existing products or product candidates 
and regulatory approvals; and 

our inability to generate revenue from acquired technology and/or products sufficient to meet our objectives in undertaking the acquisition or even to 
offset the associated acquisition and maintenance costs. 

In addition, if we undertake acquisitions, we may incur large one-time expenses and acquire intangible assets that could result in significant future amortization 
expense. Moreover, we may not be able to locate suitable acquisition opportunities and this inability could impair our ability to grow or obtain access to technology or 
products that may be important to the development of our business.

We may not be successful in obtaining or maintaining necessary rights to our product candidates through acquisitions and in-licenses.

Our programs may require the use of intellectual property rights held by third parties to which we do not have rights. In such a case, the growth of our business will 
depend in part on our ability to acquire, in-license or use these rights. However, we may be unable to acquire or in-license any compositions, methods of use, processes 
or other third-party intellectual property rights from third parties that we identify as necessary for our product candidates on reasonable terms and conditions or at all. 

The acquisition or licensing of intellectual property rights for pharmaceutical products is very competitive. If we seek to acquire or license additional intellectual 
property rights, we may face substantial competition from a number of more established companies, some of which have acknowledged strategies to license or acquire 
products, and many of which have more institutional experience and greater financial and other resources than we have. These established companies may have a 
competitive advantage over us due to their size, cash resources and greater clinical development and commercialization capabilities, as may other emerging companies 
taking similar or different approaches to product licenses and/or acquisitions. In addition, a number of established research-based pharmaceutical and biotechnology 
companies may acquire products in late stages of development to augment their internal product lines, which may provide those companies with an even greater 
competitive advantage. Furthermore, companies that perceive us to be a competitor may be unwilling to assign or license rights to us or may interfere with our 
acquisition or licensing of rights from others. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make 
an appropriate return on our investment. 

We have collaborated with U.S. academic institutions and may in the future collaborate with U.S. and foreign academic institutions to accelerate our preclinical research 
or development under written agreements with these institutions. These institutions may provide us with an option to negotiate a license to any of the institution’s rights 
in technology resulting from the collaboration. Regardless of such option, we may be unable to negotiate a license within the specified timeframe or under terms that 
are acceptable to us. 

If we are unable to successfully obtain rights to required third-party intellectual property rights or maintain the existing intellectual property rights we have on 
reasonable terms, we may have to abandon development of that program and our competitive position, business, financial condition, results of operations, and prospects 
could suffer. 

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business 
may be adversely affected. 

Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. 
We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential collaborators or customers in 
our markets of interest. At times, 

96

 
 
 
 
 
 
 
 
 
competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In 
addition, there could be potential trade name or trademark infringement claims brought by owners of other trademarks or trademarks that incorporate variations of our 
registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then 
we may not be able to compete effectively and our business may be adversely affected. We may license our trademarks and trade names to third parties, such as 
distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of 
our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names. Our efforts to 
enforce or protect our proprietary rights related to trademarks, trade names, trade secrets, domain names, copyrights or other intellectual property may be ineffective 
and could result in substantial costs and diversion of resources and could adversely affect our business, financial condition, results of operations and prospects. 

Changes in patent law in the United States or in other countries could diminish the value of patents in general, thereby impairing our ability to protect our product 
candidates. 

Our patent rights may be affected by developments or uncertainty in the United States’ or other jurisdictions’ patent statutes, patent case law, USPTO rules and 
regulations or the rules and regulations of other jurisdictions’ patent offices. 

There are a number of recent changes to U.S. patent laws that may have a significant impact on our ability to protect our technology and enforce our intellectual 
property rights. For example, on September 16, 2011, the Leahy-Smith America Invents Act, or Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a 
number of significant changes to U.S. patent law. These include provisions that affect the way patent applications will be prosecuted and may also affect patent 
litigation. In particular, under the Leahy-Smith Act, the United States transitioned in March 2013 to a “first to file” system in which the first inventor to file a patent 
application is typically entitled to the patent. Third parties are allowed to submit prior art before the issuance of a patent by the USPTO, and may become involved in 
post-grant proceedings including opposition, derivation, reexamination, inter partes review or interference proceedings challenging our patent rights or the patent rights 
of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope or enforceability of, or invalidate, our patent rights, which 
could adversely affect our competitive position. In addition, the U.S. congress may pass additional patent reform legislation that is unfavorable to us.

The Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the 
rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has 
created uncertainty with respect to the value of patents once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws and 
regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents we 
might obtain in the future. Similarly, statutory or judicial changes to the patent laws of other countries may increase the uncertainties and costs surrounding the 
prosecution of patent applications and the enforcement or defense of issued patents. 

We may not be able to protect our intellectual property rights throughout the world. 

Filing, prosecuting and defending all current and future patents in all countries throughout the world would be prohibitively expensive, and our intellectual property 
rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect 
intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing 
our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other 
jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may 
export otherwise infringing products to territories where we have patent protection but enforcement is not as strong as that in the United States. These products may 
compete with our product candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. 

The legal systems of many foreign countries do not favor the enforcement of patents and other intellectual property protection, which could make it difficult for us to 
stop the infringement of our patents or marketing of competing products in violation of our proprietary rights. For example, some foreign countries have compulsory 
licensing laws under which a patent owner must grant licenses to third parties. In addition, some countries limit the enforceability of patents against third parties, 
including government agencies or government contractors. In these countries, patents may provide limited or no benefit. Proceedings to enforce our patent rights in 
foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being 
invalidated or interpreted narrowly and our 

97

 
 
 
 
 
 
 
 
patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages 
or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be 
inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. If we or any of our licensors is forced to grant a 
license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of 
operations, and prospects may be adversely affected. 

Further, on June 1, 2023, the European Union Patent Package (EU Patent Package) regulations were implemented with the goal of providing a single pan-European 
Unitary Patent and a new European Unified Patent Court (UPC) for litigation involving European patents. As a result, all European patents, including those issued prior 
to ratification of the EU Patent Package, now by default automatically fall under the jurisdiction of the UPC. It is uncertain how the UPC will impact granted European 
patents in the biotechnology and pharmaceutical industries. Our European patent applications, if issued, could be challenged in the UPC. During the first seven years of 
the UPC’s existence, the UPC legislation allows a patent owner to opt its European patents out of the jurisdiction of the UPC. We may decide to opt out our future 
European patents from the UPC, but doing so may preclude us from realizing the benefits of the UPC. Moreover, if we do not meet all of the formalities and 
requirements for opt-out under the UPC, our future European patent applications and patents could remain under the jurisdiction of the UPC. The UPC will provide our 
competitors with a new forum to centrally revoke our European patents, and allow for the possibility of a competitor to obtain pan-European injunction. Such a loss of 
patent protection could have a material adverse impact on our business and our ability to commercialize our technology and product candidates and, resultantly, on our 
business, financial condition, prospects and results of operations.

Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed 
by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements. 

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during 
the patent process. Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the 
USPTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We employ 
reputable professionals and rely on such third parties to help us comply with these requirements and effect payment of these fees with respect to the patents and patent 
applications that we own, and if we license intellectual property we may have to rely upon our licensors to comply with these requirements and effect payment of these 
fees with respect to any patents and patent applications that we license. In many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in 
accordance with the applicable rules. However, there are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, 
resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would 
otherwise have been the case. 

If securities or industry analysts do not continue to publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our 
stock, our stock price and trading volume could decline. 

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If any of 
the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock performance, or if our clinical 
trials and operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to 
publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. 

We incur significant costs as a result of operating as a public company, and our management devotes substantial time to new compliance initiatives. We may fail to 
comply with the rules that apply to public companies, including Section 404 of the Sarbanes-Oxley Act of 2002, which could result in sanctions or other penalties 
that would harm our business. 

We incur significant legal, accounting and other expenses as a public company, including costs resulting from public company reporting obligations under the Exchange 
Act and regulations regarding corporate governance practices. The listing requirements of the Nasdaq Global Select Market and the rules of the Securities and 
Exchange Commission, or SEC, require that we satisfy certain corporate governance requirements relating to director independence, filing annual and interim reports, 
stockholder meetings, approvals and voting, soliciting proxies, conflicts of interest and a code of conduct. Our management and other personnel devote a substantial 
amount of time to ensure that we comply with all of these requirements. Moreover, the reporting requirements, rules and regulations will increase our legal and financial 
compliance costs and make some 

98

 
 
 
 
 
 
 
 
activities more time-consuming and costly. Any changes we make to comply with these obligations may not be sufficient to allow us to satisfy our obligations as a 
public company on a timely basis, or at all. These reporting requirements, rules and regulations, coupled with the increase in potential litigation exposure associated 
with being a public company, could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors or board committees or to 
serve as executive officers, or to obtain certain types of insurance, including D&O insurance, on acceptable terms. 

As a public company, we are subject to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, and the related rules of the SEC, which generally require our 
management and independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting. This assessment will need 
to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. Additionally, as a result of our ceasing to 
be an emerging growth company and being deemed a large accelerated filer as of January 1, 2024, commencing with this Annual Report on Form 10-K for the year 
ending December 31, 2023, our independent registered public accounting firm is required to issue an opinion on the effectiveness of our internal control over financial 
reporting. We expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the auditor attestation requirements of 
Section 404. Furthermore, we will also have to file a more expansive proxy statement and be subject to shorter filing deadlines, which will require additional time and 
expense as well. It may require significant resources and management oversight to maintain and, if necessary, improve our disclosure controls and procedures and 
internal control over financial reporting to meet this standard. As a result, management’s attention may be diverted from other business concerns, which could adversely 
affect our business and operating results. To comply with these requirements, we may need to hire more employees in the future or engage outside consultants, which 
would increase our costs and expenses. 

In order to provide the reports required by these rules, we must conduct reviews and testing of our internal controls. During the course of our review and testing, we 
may identify deficiencies and be unable to remediate them before we must provide the required reports. Furthermore, if we have a material weakness in our internal 
control over financial reporting, we may not detect errors on a timely basis and our audited financial statements may be materially misstated. We or our independent 
registered public accounting firm may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting, which could harm our 
operating results, cause investors to lose confidence in our reported financial information and cause the trading price of our stock to fall. In addition, as a public 
company we are required to file accurate and timely quarterly and annual reports with the SEC under the Exchange Act. In order to report our results of operations and 
financial statements on an accurate and timely basis, we will depend on CROs and contract manufacturing organizations, or CMOs, to provide timely and accurate 
notice of their costs to us and on GSK to provide timely and accurate reports of cost sharing under the GSK Collaboration Agreement. Any failure to report our 
financial results on an accurate and timely basis could result in sanctions, lawsuits, delisting of our shares from the Nasdaq Global Select Market or other adverse 
consequences that would materially harm to our business. 

If we are unable to maintain effective internal controls, our business, financial position, results of operations and prospects could be adversely affected. 

As a public company, we are subject to reporting and other obligations under the Exchange Act, including Section 404, which require annual management assessments 
of the effectiveness of our internal control over financial reporting. As a result of our ceasing to be an emerging growth company and being deemed a “large accelerated 
filer” as of January 1, 2024, commencing with this Annual Report on Form 10-K for the year ending December 31, 2023, our independent registered public accounting 
firm will be required to formally attest to the effectiveness of our internal control over financial reporting pursuant to Section 404. 

The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant 
documentation, testing and possible remediation to meet the detailed standards under the rules. During the course of its testing, our management may identify material 
weaknesses or deficiencies which may not be remedied in time to meet the deadline imposed by the Sarbanes-Oxley Act of 2002. These reporting and other obligations 
place significant demands on our management and administrative and operational resources, including accounting resources, which we expect to further increase in 
2024 when we are no longer be an emerging growth company and are deemed a large accelerated filer.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a 
process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with accounting principles generally accepted in the United States. Any failure to maintain effective internal controls could have an adverse effect on our 
business, financial position, and results of operations. 

99

 
 
 
 
 
 
 
 
If we sell shares of our common stock in future financings, stockholders may experience immediate dilution and, as a result, our stock price may decline. 

We may from time to time issue additional shares of common stock at a discount from the current trading price of our common stock. As a result, our stockholders 
would experience immediate dilution upon the purchase of any shares of our common stock sold at such discount. In addition, as opportunities present themselves, we 
may enter into financing or similar arrangements in the future, including the issuance of debt securities, preferred stock or common stock. If we issue common stock or 
securities convertible into common stock, our common stockholders would experience additional dilution and, as a result, our stock price may decline. 

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited. 

We have incurred substantial losses during our history and do not expect to become profitable in the near future, and we may never achieve profitability. Under Sections 
382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” generally defined as a greater than 50 percentage 
point change (by value) in its stock ownership by certain stockholders over a three-year period, the corporation’s ability to use its pre-change net operating loss 
carryforwards, or NOLs, and other pre-change tax attributes (such as research and development tax credits) to offset its post-change taxable income may be limited. As 
a result of such ownership changes, our ability to utilize certain NOLs and other tax attributes may be permanently limited if such attributes will expire unused. We 
have experienced ownership changes in the past, and we may experience ownership changes in the future due to subsequent shifts in our stock ownership (some of 
which may be outside our control). As a result, even if we attain profitability, we may be unable to use a material portion of our NOLs and other tax attributes to offset 
future taxable income.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment 
of management.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent changes in control or changes in 
our management without the consent of our board of directors. These provisions include the following: 

•

•

•

•

•

•

•

•

•

a classified board of directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of a majority of 
our board of directors; 

no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates; 

the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death 
or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors; 

the ability of our board of directors to authorize the issuance of shares of preferred stock and to determine the price and other terms of those shares, 
including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquiror; 

the ability of our board of directors to alter our amended and restated bylaws without obtaining stockholder approval; 

the required approval of at least 66 2/3% of the shares entitled to vote at an election of directors to adopt, amend or repeal our amended and restated 
bylaws or repeal the provisions of our amended and restated certificate of incorporation regarding the election and removal of directors; 

a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

the requirement that a special meeting of stockholders may be called only by our chief executive officer or president or by the board of directors, which 
may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors; and 

advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to propose matters to be acted 
upon at a stockholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror’s own 
slate of directors or otherwise attempting to obtain control of us. 

100

 
 
 
 
 
 
We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law. Under Section 203, a corporation may not, in 
general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other 
exceptions, the board of directors has approved the transaction. 

Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the 
amount of money available to us. 

Our amended and restated certificate of incorporation and amended and restated bylaws provide that we will indemnify our directors and officers, in each case to the 
fullest extent permitted by Delaware law. 
In addition, as permitted by Section 145 of the Delaware General Corporation Law, our amended and restated bylaws and our indemnification agreements that we have 
entered into with our directors and officers provide that: 

•

•

•

•

•

•

we will indemnify our directors and officers for serving us in those capacities or for serving other business enterprises at our request, to the fullest extent 
permitted by Delaware law. Delaware law provides that a corporation may indemnify such person if such person acted in good faith and in a manner 
such person reasonably believed to be in or not opposed to the best interests of the registrant and, with respect to any criminal proceeding, had no 
reasonable cause to believe such person’s conduct was unlawful; 

we may, in our discretion, indemnify employees and agents in those circumstances where indemnification is permitted by applicable law; 

we are required to advance expenses, as incurred, to our directors and officers in connection with defending a proceeding, except that such directors or 
officers shall undertake to repay such advances if it is ultimately determined that such person is not entitled to indemnification; 

we will not be obligated pursuant to our amended and restated bylaws to indemnify a person with respect to proceedings initiated by that person against 
us or our other indemnitees, except with respect to proceedings authorized by our board of directors or brought to enforce a right to indemnification; 

the rights conferred in our amended and restated bylaws are not exclusive, and we are authorized to enter into indemnification agreements with our 
directors, officers, employees and agents and to obtain insurance to indemnify such persons; and 

we may not retroactively amend our amended and restated bylaw provisions to reduce our indemnification obligations to directors, officers, employees 
and agents. 

If the costs of maintaining adequate D&O insurance coverage increase significantly in the future, our operating results could be materially adversely affected. Likewise, 
if any of our current D&O insurance coverage should become unavailable to us or become economically impractical, we may need to decrease our coverage limits or 
increase our self-insured retention or we may be unable to renew such insurance at all. If we incur liabilities that exceed our coverage or incur liabilities not covered by 
our insurance, we would have to self-fund any indemnification amounts owed to our directors and officers and employees in which case our results of operations and 
financial condition could be materially adversely affected. Additionally, a lack of D&O insurance may make it difficult for us to retain and attract talented and skilled 
directors and officers to serve our company, which could adversely affect our business.

Our amended and restated certificate of incorporation provides for an exclusive forum in the Court of Chancery of the State of Delaware and in the U.S. federal 
district courts for certain disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes 
with us or our directors, officers or employees. 

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any state law derivative 
action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware 
General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws, any action to interpret, apply, enforce, or 
determine the validity of our amended and restated certificate of incorporation or amended and restated bylaws, or any action asserting a claim against us that is 
governed by the internal affairs doctrine. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for 
disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees and result 
in increased costs for investors to bring a claim.

Item 1C. Cybersecurity.

Cybersecurity Risk Management and Strategy

We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems 
and information. Our cybersecurity risk management program includes a cybersecurity incident response plan. 

We design and assess our program based on the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF). This does not imply that we 
meet any particular technical standards, specifications, or requirements, only that we use the NIST CSF as a guide to help us identify, assess, and manage cybersecurity 
risks relevant to our business.

Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels 
and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas.

Our cybersecurity risk management program includes:

•

•

•

•

•

•

•

risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services, and our broader enterprise 
information technology environment;

a security team principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to 
cybersecurity incidents;

a documented set of cybersecurity policies and procedures that specifies the manner in which security controls are implemented;

the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls;

cybersecurity awareness training of our employees, incident response personnel, and senior management; 

a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and

a third-party risk management process for service providers, suppliers, and vendors who have access to our critical systems and information.

There can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, 
complied with or effective in protecting our systems and information.

We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably 
likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. For more information, see the section titled “Risk 
Factor— Our information technology systems, or those of our collaborators, CROs or other contractors or consultants, may fail or suffer security breaches, which could 
adversely affect our business. Security breaches, loss of data or financial assets, and other disruptions could compromise sensitive information related to our business or 
prevent us from accessing critical information and expose us to liability.”

Cybersecurity Governance

Our  board  of  directors  considers  cybersecurity  risk  as  part  of  its  risk  oversight  function  and  has  delegated  to  the  Audit  Committee,  or  the  Committee,  oversight  of 
cybersecurity,  data  privacy  and  other  information  technology  risks.  The  Committee  oversees  management’s  implementation  of  our  cybersecurity  risk  management 
program. The Committee is composed of members of our board of directors with diverse expertise, including risk management, public accounting, biotechnology, chief 
executive officer roles, and multiple public company directorships, which has prepared them to oversee our cybersecurity risks.

The Committee receives quarterly reports from management on our cybersecurity risks. In addition, management updates the Committee, as necessary, regarding any 
material cybersecurity incidents, as well as any incidents with lesser impact potential.

The Committee reports to our full board of directors regarding its activities, including those related to cybersecurity. The full board of directors also receives briefings 
from  management  on  our  cybersecurity  risk  management  program.  Board  members  receive  presentations  on  cybersecurity  topics  from  our  Senior  Vice  President 
(“SVP”), Head of Finance and Investor Relations, Chief Legal Officer, internal security staff and external experts as part of the board of directors’ continuing education 
on topics that impact public companies.

Our management team, including our SVP, Head of Finance and Investor Relations and Chief Legal Officer, is responsible for assessing and managing our material 
risks  from  cybersecurity  threats.  The  team  has  primary  responsibility  for  our  overall  cybersecurity  risk  management  program  and  supervises  both  our  internal 
cybersecurity personnel and our retained external cybersecurity consultants. Our management team’s experience includes monitoring the cybersecurity landscape for 
new risks and best practices, developing and executing cybersecurity strategies, overseeing related governance policies, testing compliance with applicable technical 
standards, remediating known risks and leading employee training programs. 

Our  management  team  supervises  efforts  to  prevent,  detect,  mitigate,  and  remediate  cybersecurity  risks  and  incidents  through  various  means,  which  may  include 
briefings  from  internal  security  personnel;  threat  intelligence  and  other  information  obtained  from  governmental,  public  or  private  sources,  including  external 
consultants engaged by us; and alerts and reports produced by security tools deployed in the information technology environment.

Item 2. Properties 

Our corporate headquarters is located in South San Francisco, California, where we lease and occupy approximately 29,600 square feet of office and laboratory space. 
The current term of our South San Francisco lease expires in July 2024, with an option to extend the term through July 2026. 

In June 2023, we entered into a lease agreement for 43,966 square feet of space at 5000 Shoreline Court, South San Francisco, California. The lease term is expected to 
commence in June 2024 and the lease term is one hundred twenty months.

In November 2023, we additionally entered into a lease for an office located in San Diego, California, where we occupy approximately 5,700 square feet of office 
space. The lease commenced in December 2023 and expires in March 2028. 

We believe our existing facilities are sufficient for our needs for the foreseeable future. To meet the future needs of our business, we may lease additional or alternate 
space, and we believe suitable additional or alternative space will be available in the future on commercially reasonable terms. 

Item 3. Legal Proceedings

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the 
opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on our business, 
financial condition, results of operations and prospects because of defense and settlement costs, diversion of management resources and other factors.

Overview 

We are a precision medicine oncology company committed to the discovery and development of targeted therapeutics for patient populations selected using molecular 
diagnostics. Our approach integrates small molecule drug discovery with extensive capabilities in identifying and validating translational biomarkers to develop 
targeted therapies for select patient populations that are most likely to benefit from these targeted therapies. Our small molecule drug discovery expertise includes 
discovery and development of small molecule therapeutics. We are applying these capabilities to develop a robust pipeline in precision medicine oncology.

Our clinical pipeline includes four potential first-in-class clinical-stage product candidates – darovasertib (PKC), IDE397 (MAT2A), IDE161 (PARG) and GSK101 (Pol 
Theta  Helicase).  We  own  or  control  all  commercial  rights  of  the  three  most-advanced  of  these  product  candidates:  darovasertib,  IDE397  and  IDE161.  We  are  also 
advancing  our  Werner  Helicase  program  for  which  we  have  selected  a  development  candidate  in  collaboration  with  GlaxoSmithKline,  or  GSK  and,  subject  to 
investigational  new  drug-,  or  IND-,  enabling  studies,  are  targeting  an  IND  in  2024.  We  also  have  multiple  earlier-stage  preclinical  programs.  We  have  established 
selective, value-accretive collaborations with leading pharmaceutical companies to support our clinical development activities.

Darovasertib – PKC Inhibitor Clinical Candidate in Metastatic Uveal Melanoma and Primary Uveal Melanoma

Our most advanced clinical program is evaluating darovasertib, or IDE196 which we in-licensed from Novartis, a small molecule protein kinase C, or PKC, inhibitor, in 
uveal melanoma, or UM. We are evaluating darovasertib in combination with crizotinib in a potential registrational clinical trial in patients having MUM. We are also 
evaluating darovasertib as monotherapy in a Phase 2 clinical trial in primary UM. We are further evaluating darovasertib in combination with crizotinib in a Phase 2 
clinical trial in patients with cutaneous melanoma. 

We have initiated and achieved double-digit patient enrollment and have opened multiple clinical sites, including international sites, where we are recruiting patients for 
enrollment in a potential registration-enabling Phase 2/3 clinical trial, designated as IDE196-002, to evaluate darovasertib in combination with crizotinib, Pfizer’s 
investigational cMET inhibitor, in patients having metastatic UM, or MUM, with human leukocyte antigen-, or HLA-A*02:01 negative, or HLA-A2(-), serotype, as part 
of a second Clinical Trial Collaboration and Supply Agreement, or Second Pfizer agreement, with Pfizer. We are targeting clinical program update(s) in 2024.

We are also planning to enroll additional HLA-A*02:01 positive, or HLA-A2(+), patients as an independent clinical strategy to address HLA-A2(+) MUM patients, in a 
clinical study. We are further evaluating darovasertib in combination with crizotinib in a Phase 2 expansion arm of IDE196-001 clinical trial in patients with cutaneous 
melanoma, alternatively referred to as skin melanoma. 

We separately initiated and have achieved double-digit patient enrollment in our Phase 2 clinical trial, designated as IDE196-009, evaluating darovasertib as single-
agent neoadjuvant and adjuvant therapy in patients having primary UM, with ongoing enrollment and multiple clinical sites open. We are targeting a clinical efficacy 
update in mid-year 2024 and regulatory guidance update in 2024.

We are also supporting evaluation of darovasertib as single-agent neoadjuvant and adjuvant therapy in primary UM in an ongoing investigator-sponsored clinical trial, 
or IST, captioned as “Neoadjuvant / Adjuvant trial of Darovasertib in Ocular Melanoma”, or NADOM, and led by St. Vincent’s Hospital in Sydney with the 
participation of Alfred Health and the Royal Victorian Eye and Ear Hospital in Melbourne. We are targeting a clinical efficacy update in mid-year 2024.

We own or control all commercial rights in our darovasertib program in uveal melanoma, including in MUM and in primary UM, subject to certain economic 
obligations pursuant to our exclusive, worldwide license to darovasertib with Novartis.

IDE397 – MAT2A Inhibitor Clinical Candidate in Tumors with MTAP Deletion

IDE397, our small molecule methionine adenosyltransferase 2a, or MAT2A, inhibitor, is being evaluated in a Phase 1/2 clinical trial. We are actively enrolling into the 
Phase 2 monotherapy expansion cohort in selected priority indications for patients having tumors with methylthioadenosine phosphorylase, or MTAP, gene deletion, 
including squamous non-small cell lung cancer, or NSCLC, bladder, gastric and esophageal cancers. We observed IDE397 monotherapy responses in multiple priority 
solid tumor types based on experience across several patients in the early phase of the Phase 2 dose expansion.

We are enrolling patients into a Phase 2 clinical trial designated as IDE397-001 to evaluate IDE397 for patients having certain tumors with MTAP gene deletion. We are 
proceeding with enrollment of MTAP-deletion patients into a monotherapy Phase 2 expansion cohort with an initial focus on high priority solid tumor types, including 
squamous NSCLC, bladder, esophageal and gastric cancers. In June 2023, we announced selection of a Phase 2 monotherapy expansion dose for IDE397 and in 
connection therewith, reported preliminary evidence of clinical activity as monotherapy. 

In collaboration with Amgen as part of the Amgen Clinical Trial Collaboration and Supply Agreement, or Amgen CTCSA, we initiated patient enrollment in the 
Amgen-sponsored Phase 1/2 clinical trial evaluating IDE397 in combination with AMG 193, the Amgen investigational MTA-cooperative protein arginine 
methyltransferase 5, or PRMT5, inhibitor, in patients having tumors with MTAP deletion, or the IDE397/AMG 193 combination study. This potential first-in-class 
synthetic lethality combination targets mechanistically complementary nodes of the MTAP methylation pathway – MAT2A and PRMT5 and is supported by data 
demonstrating preclinical anti-tumor efficacy presented at the 2023 Annual Meeting of the American Association for Cancer Research, or AACR 2023. We are 
targeting the development of a joint publication strategy in 2024.

We are collaborating with Gilead to clinically evaluate IDE397 in combination with Trodelvy, the Gilead Trop-2 directed ADC, in patients having MTAP deletion 
bladder cancer, in an IDEAYA-sponsored clinical trial pursuant to the Gilead CSCSA. We anticipate enrolling the first patient in this clinical trial in mid-year 2024.

We own all right, title and interest in and to IDE397 and the MAT2A program, including all worldwide commercial rights thereto.

IDE161 – PARG Inhibitor Clinical Candidate in Tumors with Homologous Recombination Deficiency 

We are evaluating IDE161, a small molecule inhibitor of PARG being evaluated in a Phase 1/2 clinical trial designated as IDE161-001 for patients having tumors with 
HRD and potentially other genetic and/or molecular signatures. PARG is a novel target in a clinically validated biological pathway. PARG functions as a regulator of 
DNA repair in the same biochemical pathway as PARP. PARG hydrolyzes poly (ADP-ribose), or PAR, chains that are polymerized by PARP enzymes, completing the 
PAR cycle. Small molecule inhibitors of PARG result in a dose dependent increase in cellular PAR after DNA damage. PARG is a mechanistically distinct target 
relative to PARP.

We are progressing with enrollment of patients having tumors with HRD into the Phase 1 expansion portion of the Phase 1/2 clinical trial in selected priority tumors. In 
parallel, we are also continuing with Phase 1 dose optimization to confirm a move-forward expansion dose for the planned Phase 2 portion of the clinical trial. We are 
targeting clinical program update(s) in 2024. We are also validating IDE161 combination opportunities preclinically and targeting identification of potential 
combination(s) in 2024.

We received Fast Track Designation from the U.S. Food and Drug Administration, or FDA for IDE161 for ovarian cancer and breast cancer indications, specifically for 
the treatment of (i) adult, pretreated, platinum-resistant advanced or metastatic ovarian cancer patients having tumors with BRCA1/2 mutations and (ii) adult, 
pretreated, advanced or metastatic hormone receptor positive, or HR+, Her2- and BRCA1/2 mutant breast cancer patients.

We own or control all commercial rights in our PARG program, subject to certain economic obligations pursuant to our exclusive, worldwide license to certain PARG 
inhibitors, including IDE161, with CRT and University of Manchester.

Pol Theta

GSK101 (IDE705), our Pol Theta Helicase inhibitor clinical development candidate, is a potential first-in-class small molecule inhibitor of the helicase domain of 
Polymerase Theta, or Pol Theta. GSK101 was discovered and evaluated in preclinical studies in collaboration with GSK. Pursuant to the GSK Collaboration 
Agreement, GSK holds a global, exclusive 

106

 
 
 
 
 
 
 
 
 
 
 
 
 
 
license to develop and commercialize Pol Theta products arising out of the Pol Theta program. GSK is leading clinical development for GSK101 and is responsible for 
all research and development costs for the Pol Theta program. 

We are evaluating GSK101 in combination with niraparib, the GSK small molecule inhibitor of PARP for the treatment of patients having tumors with BRCA or other 
HR mutations, or HRD in a Phase 1 clinical trial. GSK has dosed the first patient in this trial.

GSK is leading clinical development of GSK101 pursuant to the GSK Collaboration Agreement. GSK is responsible for all research and development costs for the Pol 
Theta program.

We have the potential to receive an additional $10.0 million milestone payment upon initiation of Phase 1 clinical dose expansion. In August 2023, we achieved and 
earned a $7.0 million milestone based on acceptance of the IND by the FDA. An earlier preclinical development $3.0 million milestone payment from GSK was 
achieved in August 2022 in connection with ongoing IND-enabling studies to support evaluation of GSK101.

We have the potential to earn further aggregate later‐stage development and regulatory milestones of up to $465 million. Upon commercialization, we will be eligible to 
receive up to $475 million of commercial milestones, and tiered royalties on global net sales of GSK101 – ranging from high single-digit to sub-teen double-digit 
percentages, subject to certain customary reductions. 

WRN Program in Tumors with High Microsatellite Instability

We selected a Werner Helicase Inhibitor DC in collaboration with GSK. This Werner Helicase Inhibitor DC is targeting the helicase domain of the Werner, or WRN, 
protein, for patients having tumors with high microsatellite instability, or MSI. Subject to successful completion of ongoing IND-enabling studies, we are targeting an 
IND submission in 2024 to enable first-in-human clinical evaluation of Werner Helicase Inhibitor DC for patients having tumors with high MSI. 

We are collaborating with GSK on the ongoing IND-enabling studies and, subject to IND submission and FDA allowance of clinical development, GSK will lead 
clinical development for the Werner Helicase program.

In October 2023, we earned a $3 million milestone in connection with IND-enabling studies, for which payment was received in November 2023. We have the potential 
to earn up to an additional $17 million aggregate milestone payments through early Phase 1 clinical studies, including $7.0 million upon IND clearance. We are also 
eligible to receive additional future aggregate total development milestones of up to $465 million. Upon commercialization, we will be eligible to receive up to $475 
million of commercial milestones, 50% of U.S. net profits and tiered royalties on global non-U.S. net sales of the Werner Helicase Inhibitor DC – ranging from high 
single-digit to sub-teen double-digit percentages, subject to certain customary reductions.

Other Pipeline Programs (Defined Biomarkers)

We have initiated early preclinical research programs focused on pharmacological inhibition of several new targets, or NTs, for patients with solid tumors characterized 
by defined biomarkers based on genetic mutations and/or molecular signatures. We believe these research programs have the potential for discovery and development of 
first-in-class or unique-in-class or best-in-class therapeutics. We are targeting development candidate nominations in 2024 for multiple NTs, including a development 
candidate to treat MTAP-deletion solid tumors. We own or control all commercial rights in our next-generation programs. 

New Target and Biomarker Discovery Platform

We have invested significantly and continue to invest in capabilities for identification and validation of new precision medicine targets and biomarkers for patient 
selection. For targets of interest, we advance our research to discover therapeutic drugs and to further qualify relevant biomarkers. 

We own or control all commercial rights in programs directed to targets identified in on our new target and biomarker discovery platform.

Corporate Update

We do not have any products approved for sale and have not generated any product revenue since inception. We have funded our operations through December 31, 2023 
primarily through the sale and issuance of common stock, pre-funded warrants, redeemable convertible preferred stock, and convertible promissory notes, including our 
initial public offering, or IPO, in May 2019, a follow-on underwritten public offering in June 2020, a direct private placement equity investment by Glaxo Group 
Limited, an affiliate of GSK, in June 2020, the sale and issuance of common stock under our at-the-market facility pursuant to the August 2020 and January 2021 Sales 
Agreements with Jefferies as sales agent, and through additional follow-on underwritten public offerings in July 2021, September 2022, April 2023 and October 2023. 
Additionally, we received a non-dilutive upfront cash payment of $100 million from GSK in connection with the GSK Collaboration Agreement in July 2020. As of 
December 31, 2023, GSK has made aggregate payments to us in the amount of $13.0 million for the achievement of certain development and regulatory milestones 
with respect to Pol Theta and WRN products.

Since our inception in June 2015, we have devoted substantially all of our resources to discovering and developing our product candidates. We have incurred significant 
operating losses to date and expect that our operating expenses will increase significantly as we advance our product candidates through preclinical and clinical 
development; seek regulatory approval, and prepare for, and, if approved, proceed to commercialization; acquire, discover, validate and develop additional product 
candidates; obtain, maintain, protect and enforce our intellectual property portfolio; and hire additional personnel. Certain program costs that contribute to our operating 
expenses have been and/or will be reimbursed by GSK pursuant to the GSK Collaboration Agreement, including 100% of costs we incur for research we perform in 
connection with the Pol Theta program and 80% of the aggregate program costs incurred by us and GSK for research each of us performs for the Werner Helicase 
program. We anticipate that payments which we may make to Amgen will also contribute to our operating expenses as they are reimbursed by us pursuant to the Amgen 
CTCSA, including 50% of external costs Amgen incurs in connection with the Amgen-sponsored and executed IDE397 / AMG 193 Combination Study. We anticipate 
that we will also incur costs in accordance with the Gilead CSCSA. Gilead will bear internal or external costs incurred in connection with its supply of Trodelvy. We 
will bear all internal and external costs and expenses associated with the conduct of the combination study. In addition, we expect to incur additional costs associated 
with operating as a public company. 

Our net losses were $113.0 million and $58.7 million for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, we had an accumulated 
deficit of $348.4 million. 

Our ability to generate product revenue will depend on the successful development, regulatory approval and eventual commercialization of one or more of our product 
candidates, ourselves, or for some programs, in collaboration with our strategic partners. 

Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings, or 
other capital sources, including potential collaborations with other companies or other strategic transactions. Adequate funding may not be available to us on acceptable 
terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, scale back or discontinue the 
development and commercialization of our product candidates.

As of December 31, 2023, we had cash, cash equivalents, and short-term and long-term marketable securities of $632.6 million. 

We believe that our cash, cash equivalents, and short-term and long-term marketable securities will be sufficient to fund our planned operations for at least twelve 
months from the date of the issuance of our Annual Report on Form 10-K filed February 20, 2024. 

These funds will support our efforts through potential achievement of multiple preclinical and clinical milestones across multiple programs. 

Components of Operating Results

Collaboration Revenues

To date, we have not generated any revenue from product sales, and we do not expect to generate any revenue from product sales unless and until we are able to initiate 
a registrational clinical trial, obtain regulatory approval and commercialize one of our product candidates in the future. Our revenue consists exclusively of 
collaboration revenue under the GSK Collaboration 

109

 
 
 
 
 
 
 
 
 
 
 
 
 
Agreement, including amounts that are recognized related to previously received upfront payments and amounts due and payable to us for research and development 
services. The amount of revenue recognized related to the GSK Collaboration Agreement, including as related to the previously received upfront payment or to certain 
development milestone payments, may vary considerably by period and certain components thereof may generally decrease year-over-year as we satisfy remaining 
performance obligations, for example, relating to the Pol Theta and WRN R&D Services. As of December 31, 2023, we have fully recognized the contract liabilities 
related to the upfront payment and reimbursements for the research and development performance obligations under the GSK Collaboration Agreement. There are no 
remaining contract liabilities as of December 31, 2023 as we concluded all the research and development performance obligations under the GSK Collaboration 
Agreement. The future revenue recognition will be contingent on additional milestone earned, profit sharing and royalties on any net product sales under our 
collaborations. We expect that any revenue we recognize or generate under the GSK Collaboration Agreement will fluctuate from period to period due to period to 
period variability in milestone payments and other payments. 

Operating Expenses

Research and Development Expenses

Substantially all of our research and development expenses consist of expenses incurred in connection with discovery and development of our product candidates. 
These expenses include certain payroll and personnel-related expenses, including salaries, employee benefit costs and stock-based compensation expenses for our 
research and product development employees, fees to third parties to conduct certain research and development activities on our behalf including fees to CMOs and 
CROs in support of manufacturing and clinical activity for darovasertib, IDE397, IDE161 and WRN, consulting costs, costs for laboratory supplies, costs for product 
licenses and allocated overhead, including rent, equipment, depreciation, information technology costs and utilities. We expense both internal and external research and 
development expenses as they are incurred.

We have entered into various agreements with CMOs and CROs. Our research and development accruals are estimated based on the level of services performed, 
progress of the studies, including the phase or completion of events, and contracted costs. The estimated costs of research and development provided, but not yet 
invoiced, are included in accrued liabilities on the balance sheet. If the actual timing of the performance of services or the level of effort varies from the original 
estimates, we will adjust the accrual accordingly. Payments made to CMOs and CROs under these arrangements in advance of the performance of the related services 
are recorded as prepaid expenses and other current assets until the services are rendered.

Costs of certain activities, such as preclinical studies, are generally recognized based on an evaluation of the progress to completion of specific tasks. Nonrefundable 
payments made prior to the receipt of goods or services that will be used or rendered for future research and development activities are deferred and capitalized as 
prepaid expenses and other current assets on our balance sheet. The capitalized amounts are recognized as expense as the goods are delivered or the related services are 
performed.

We do not allocate our internal costs by product candidate, including internal costs, such as payroll and other personnel expenses, laboratory supplies and allocated 
overhead. With respect to internal costs, several of our departments support multiple product candidate research and development programs, and therefore the costs 
cannot be allocated to a particular product candidate or development program. The following table summarizes our external clinical development expenses by program:

External clinical development expenses include manufacturing and clinical trial costs. These expenses are primarily for services provided by external consultants, CMOs and CROs.
IDE397 includes costs from Amgen Clinical Trial Collaboration and Supply Agreement

We are focusing substantially all of our resources on the development of our product candidates. We expect our research and development expenses to increase 
substantially during the next few years, as we seek to initiate and/or advance clinical trials for our product candidates, complete our clinical program, pursue regulatory 
approval of our product candidates and prepare for a possible commercial launch. Predicting the timing or the cost to complete our clinical program or validation of our 
commercial manufacturing and supply processes is difficult and delays may occur because of many factors, including factors outside of our control. For example, if the 
FDA or other regulatory authorities were to require us to conduct clinical trials 

110

 
 
 
 
 
 
   
 
 
     
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant 
additional financial resources and time on the completion of clinical development. Furthermore, we are unable to predict when or if our product candidates will receive 
regulatory approval with any certainty. 

General and Administrative Expenses 

General and administrative expenses consist primarily of payroll and personnel-related expenses, including salaries, employee benefit costs and stock-based 
compensation expense, professional fees for legal, patent, consulting, accounting and tax services, allocated overhead, including rent, equipment, depreciation, 
information technology costs and utilities, and other general operating expenses not otherwise classified as research and development expenses. 

We anticipate that our general and administrative expenses will increase, as a result of increased personnel costs, including salaries, benefits and stock-based 
compensation expense, patent costs for our product candidates, expanded infrastructure and higher consulting, legal and accounting services associated with 
maintaining compliance with our Nasdaq stock exchange listing and requirements of the Securities and Exchange Commission, or the SEC, investor relations costs and 
director and officer insurance policy premiums associated with being a public company. 

Other Income (Expense)

Interest Income and Other Income (Expense), Net

Interest income and other income (expense), net consists primarily of interest income earned on our cash, cash equivalents and marketable securities.

Collaboration revenue decreased by $27.5 million, or 54%, during the year ended December 31, 2023 compared to the year ended December 31, 2022. In July 2020, the 
GSK Collaboration Agreement became effective, and we started recognizing collaboration revenue, which consists of revenue from preclinical and Phase 1 
monotherapy clinical research and development services under the MAT2A program as well as preclinical research services and the related license under the Pol Theta 
and WRN programs. Revenue we recognize from satisfaction of performance obligations under the GSK Collaboration Agreement is impacted by our estimates of the 
remaining costs to complete our obligations, which may vary due to changes to prospective collaboration research budgets or changes to respective allocation of 
resources and in any case require significant judgment, and may cause fluctuation in the revenue recognized from period to period.

During 2023, the Company recognized $23.4 million in revenue resulting from the progress in WRN R&D services and the Pol Theta program's IND acceptance 
milestone achievement and WRN program's toxicology study initiation milestone achievement. 

As of December 31, 2023, we have fully recognized the contract liabilities related to the upfront payment and reimbursements for the research and development 
performance obligations under the GSK Collaboration Agreement. There are no remaining contract liabilities as of December 31, 2023 as we concluded all the research 
and development performance obligations under the GSK Collaboration Agreement. The future revenue recognition will be contingent on additional milestones earned, 
profit sharing and royalties on any net product sales under our collaborations. We expect that any revenue we recognize or generate under the GSK Collaboration 
Agreement will fluctuate from period to period due to period to period variability in milestone payments and other payments. 

Research and Development Expenses 

Research and development expenses increased by $40.0 million, or 45%, during the year ended December 31, 2023 compared to the year ended December 31, 2022. 
The increase in research and development expenses was primarily due to increases of $24.5 million in fees paid to CROs, CMOs and consultants related to the 
advancement of our lead product candidates through preclinical and clinical studies, $12.3 million in personnel-related expenses, including salaries, benefits and stock-
based compensation, primarily related to an increase in headcount to support our growth, and $3.2 million in costs for laboratory supplies, facilities, software and 
insurance premiums to support our research and development programs.

General and Administrative Expenses 

General and administrative expenses increased by $4.4 million, or 18%, during the year ended December 31, 2023 compared to the year ended December 31, 2022. The 
increase in general and administrative expenses was primarily due to increases of $1.6 million for consulting and legal services and $3.5 million in personnel-related 
expenses, including salaries, benefits and stock-based compensation, related to an increase in headcount to support our growth, partially offset by a decrease in $0.1 
million in software licenses and facility costs, and $0.6 million in directors and officer's insurance premiums.

Interest Income and Other Income (Expense), Net

Interest income increased by $17.6 million, or 458%, during the year ended December 31, 2023 compared to the year ended December 31, 2022, primarily due to 
higher investment balances and interest rates.

Liquidity and Capital Resources; Plan of Operations 

Sources of Liquidity 

We have funded our operations primarily through the sale and issuance of common stock, pre-funded warrants, redeemable convertible preferred stock, and convertible 
promissory notes, the up-front and milestone payment received from GSK. As of December 31, 2023, we had cash, cash equivalents and marketable securities of 
$632.6 million, consisting primarily of money market funds, U.S. government securities, commercial paper, and corporate bonds.

Material Cash Requirements 

We have incurred net losses since our inception. For the years ended December 31, 2023 and December 31, 2022, we had net losses of $113.0 million and $58.7 
million, respectively, and we expect to incur substantial additional losses in future periods. As of December 31, 2023, we had an accumulated deficit of $348.4 million. 
Based on our current business plan, we believe that our existing cash, cash equivalents and marketable securities will be sufficient to fund our planned operations for at 
least the next 12 months from the issuance date of this Annual Report on Form 10-K. 

To date, we have not generated any product revenue. We do not expect to generate any meaningful product revenue unless and until we obtain regulatory approval of 
and commercialize any of our product candidates, and we do not know when, or if, it will occur. We expect to continue to incur significant losses for the foreseeable 
future, and we expect the losses to increase as we continue the development of, and seek regulatory approvals for, our product candidates and begin to commercialize 
any approved products. We are subject to all of the risks typically related to the development of new product candidates, and we may encounter unforeseen expenses, 
difficulties, complications, delays and other unknown factors that may adversely affect our business. Moreover, we expect to incur additional costs associated with 
operating as a public company. 

112

 
 
We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable future. We may seek to raise capital through 
private or public equity or debt financings, collaboration or other arrangements with corporate sources, or through other sources of financing. Adequate additional 
funding may not be available to us on acceptable terms or at all. Our failure to raise capital as and when needed would have a negative impact on our financial condition 
and our ability to pursue our business strategies. We anticipate that we will need to raise substantial additional capital, the requirements for which will depend on many 
factors, including: 

•

•

•

•

•

•

•

•

•

•

the scope, timing, rate of progress and costs of our drug discovery, preclinical development activities, laboratory testing and clinical trials for our product 
candidates;

the number and scope of clinical programs we decide to pursue;

the scope and costs of manufacturing development and commercial manufacturing activities;

the extent to which we acquire or in-license other product candidates and technologies;

the cost, timing and outcome of regulatory review of our product candidates; 

the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual 
property-related claims; 

our ability to establish and maintain collaborations on favorable terms, if at all;

our efforts to enhance operational systems and our ability to attract, hire and retain qualified personnel, including personnel to support the development 
of our product candidates;

the costs associated with being a public company; and 

the cost and timing associated with commercializing our product candidates, if they receive marketing approval.

A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly change the costs and 
timing associated with the development of that product candidate. Furthermore, our operating plans may change in the future, and we will continue to require additional 
capital to meet operational needs and capital requirements associated with such operating plans. If we raise additional funds by issuing equity securities, our 
stockholders may experience dilution. Any future debt financing into which we enter may impose upon us additional covenants that restrict our operations, including 
limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments or engage in certain merger, 
consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we 
are unable to raise additional funds when needed, we may be required to delay, reduce, or terminate some or all of our development programs and clinical trials. We 
may also be required to sell or license to others rights to our product candidates in certain territories or indications that we would prefer to develop and commercialize 
ourselves.

We lease our laboratory and office facilities in South San Francisco, California under operating leases with expiration dates in July 2024. In May 2018, we amended our 
South San Francisco facility lease agreement to expand the size of the original premises by adding approximately 7,340 rentable square feet of additional space. In 
September 2019, we further amended our South San Francisco facility lease agreement to expand the size of the premises by adding 5,588 rentable square feet of 
additional space. As of December 31, 2023, we expect to make the total lease payments of $1.6 million through July 2024. 

In June 2023, we entered into a lease agreement for 43,966 square feet of space at 5000 Shoreline Court, South San Francisco, California. The lease term is expected to 
commence in June 2024 and the lease term is one hundred twenty months. In November 2023, we additionally entered into a lease for an office located in San Diego, 
California, where we occupy approximately 5,700 square feet of office space. The lease commenced in December 2023 and expires in March 2028. 

We enter into contracts in the normal course of business with third-party contract organizations for preclinical and clinical studies and testing, manufacture and supply 
of our preclinical and clinical materials and providing other services and products for operating purposes. These contracts generally provide for termination following a 
certain period after notice, and therefore we believe that our non-cancelable obligations under these agreements are not material. 

Pursuant to the GSK Collaboration Agreement, we will be responsible for 20% of global research and development costs for the WRN program. The cost-sharing 
percentages will be adjusted based on the actual ratio of U.S. to global profits for WRN products, as measured three and six years after global commercial launch 
thereof. We may opt out of 50% U.S. net profit share and corresponding development cost share for the WRN program.

In September 2018, we entered into a license agreement with Novartis to develop and commercialize Novartis’ LXS196 (also known as IDE196), a Phase 1 PKC 
inhibitor, for the treatment of cancers having GNAQ and GNA11 mutations. We have renamed Novartis’ LXS196 oncology as IDE196, and which has a non-
proprietary name of darovasertib. We paid Novartis 

113

 
 
 
 
an upfront payment of $2.5 million and issued 263,615 shares of our Series B redeemable convertible preferred stock concurrently with the execution of the license 
agreement. Subject to completion of certain clinical and regulatory development milestones, we agreed to make milestone payments in the aggregate of up to $9.0 
million, and subject to achievement of certain commercial sales milestones, we agreed to make milestone payments in the aggregate of up to $20.0 million. We also 
agreed to pay mid to high single-digit tiered royalty payments based on annual worldwide net sales of licensed products, payable on a licensed product-by-licensed 
product and country by country basis until the latest of the expiration of the last to expire exclusively licensed patent, the expiration of regulatory exclusivity, and the 
ten year anniversary of the first commercial sale of such product in such country. The royalty payments are subject to reductions for lack of patent coverage, loss of 
market exclusivity, and payment obligations for third-party licenses. 

In March 2020, we entered into the Pfizer Agreement. Pursuant to the Pfizer Agreement, as amended in September 2020, April 2021, September 2021 and May 2023, 
Pfizer supplies us with their MEK inhibitor, binimetinib, and their cMET inhibitor, crizotinib, to evaluate combinations of darovasertib independently with each of the 
Pfizer compounds, in patients with tumors harboring activating GNAQ or GNA11 mutations. Under the Pfizer Agreement, we are the sponsor of the combination 
studies and will provide darovasertib and pay for the costs of the combination studies. Pfizer will provide binimetinib and crizotinib for use in the clinical trial at no cost 
to us. The Pfizer Agreement provides that we and Pfizer will jointly own clinical data generated from the clinical trial and will also jointly own inventions, if any, 
relating to the combined use of darovasertib and binimetinib, or independently, to the combined use of darovasertib and crizotinib. We and Pfizer have formed a joint 
development committee responsible for coordinating all regulatory and other activities under the agreement. 

We have further expanded the scope of our relationship with Pfizer, entering into additional agreements to facilitate evaluation of darovasertib in combination with 
crizotinib in a potential registrational clinical trial in MUM and separately, in combination with crizotinib in other cMET-driven tumor indications. 

In March 2022, we and Pfizer entered into the Second Pfizer Agreement pursuant to which we may, subject to FDA feedback and guidance, evaluate darovasertib and 
crizotinib as a combination therapy in MUM in a planned Phase 2/3 potential registration-enabling clinical trial. Pursuant to the Second Pfizer Agreement, we are the 
sponsor of the planned combination trial and we will provide darovasertib and pay for the costs of the combination trial; Pfizer will provide crizotinib for the planned 
combination trial at no cost to us for up to an agreed-upon number of MUM patients. We and Pfizer will jointly own clinical data from the planned combination trial 
and all inventions relating to the combined use of darovasertib and crizotinib. We and Pfizer have formed a joint development committee responsible for coordinating 
all regulatory and other activities under the Second Pfizer Agreement. 

Separately, in March 2022, we and Pfizer also entered into the Third Pfizer Agreement pursuant to which we may, subject to preclinical validation and FDA feedback 
and guidance, evaluate darovasertib and crizotinib, as a combination therapy in cMET-driven tumors such as NSCLC and/or HCC in a Phase 1 clinical trial. Pursuant to 
the Third Pfizer Agreement, we are the sponsor of the planned combination trial, and we will provide darovasertib and pay for the costs of the combination trial; Pfizer 
will provide crizotinib for the planned combination trial at no cost to us. We and Pfizer will jointly own clinical data from the planned combination trial and all 
inventions relating to the combined use of darovasertib and crizotinib. We and Pfizer had formed a joint development committee responsible for coordinating all 
regulatory and other activities under the Third Pfizer Agreement.

In May 2023, we continued our relationship with Pfizer by entering into Amendment No. 4 to the Pfizer Agreement relating to the supply of crizotinib in support of this 
Phase 2 clinical trial, pursuant to which Pfizer will continue to provide us with an additional defined quantity of crizotinib at no cost.

We also expanded our relationship with Pfizer in May 2023 under an Amendment No. 1 to the Second Pfizer Agreement to support the Phase 2/3 registrational trial to 
evaluate darovasertib and crizotinib as a combination therapy in MUM. Under the as-amended Second Pfizer Agreement, Pfizer will provide us with a first defined 
quantity of crizotinib at no cost, as well as an additional second defined quantity of crizotinib at a lump-sum cost. Under Amendment No. 1 to the Second Pfizer 
Agreement, we also terminated the Third Pfizer Agreement. 

In January 2022, we exercised our option for an exclusive worldwide license rights covering a broad class of PARG inhibitors from Cancer Research Technology Ltd. 
(CRT) and the University of Manchester, and in connection therewith, paid a one-time option exercise fee of £250,000. Certain of the clinical and regulatory milestones 
are related to and may be due and payable by us if certain milestones are achieved in connection with the IDE161-001 Phase 1/2 clinical trial. We will be obligated to 
make future milestone payments to CRT aggregating up to £18.75 million upon the achievement of specific development and regulatory approval events for 
development of a PARG inhibitor in oncologic diseases, including an aggregate of up to £1.5 million and up to £2.25 million for the achievement of certain Phase 2 and 
Phase 3 development milestones, respectively, in each case as relating to first (e.g., a breast cancer) and second (e.g., ovarian cancer) tumor histologies.

114

 
 
 
 
 
 
 
 
In April 2023, we incurred an obligation to pay milestone payments in an aggregate amount of £750,000 to CRT based upon the achievement of certain milestones 
relating to first and second tumor histologies in connection with the Phase 1 portion of the Phase 1/2 clinical trial in oncologic diseases.

Following our exercise of the option, if we sublicense certain intellectual property developed under the agreement or Cancer Research UK background patents 
specifically relating to PARG, we will also have an obligation to pay to Cancer Research UK low double digit percentage of sublicense revenue we receive, if any. If the 
agreement is terminated due to our material breach, then we are eligible to receive a percentage of sublicensing revenue that Cancer Research UK receives for licensing 
intellectual property. 

In July 2022, we entered into the Amgen CTCSA to clinically evaluate IDE397 in combination with AMG 193 in patients having MTAP-null solid tumors, in a Phase 
1/2 clinical trial. Under the mutually non-exclusive Amgen CTCSA, we will provide IDE397 drug supply to Amgen, who will be the sponsor of the Phase 1 clinical 
combination trial evaluating IDE397 and AMG 193. Each party will pay for fifty percent (50%) of the external third-party costs of the combination study. Each party 
will be responsible for its own internal costs and expenses in support of the combination study. We and Amgen will jointly oversee clinical development of the 
combination therapy through a Joint Oversight Committee responsible for coordinating all regulatory and other activities under the Amgen CTCSA. The parties will 
jointly own collaboration data and combination-related intellectual property, if any, arising from the combination clinical trial. We and Amgen each retain commercial 
rights to our respective compounds, including with respect to use as a monotherapy agent or combination agent. 

In November 2023, we entered into the Gilead CSCSA with Gilead to clinically evaluate IDE397 in combination with Trodelvy (sacituzumab-govitecan-hziy), a Trop-2 
directed ADC, in patients having MTAP-deletion bladder cancer, in a Phase 1 clinical trial. Under the mutually non-exclusive Gilead CSCSA, we will receive Trodelvy 
drug supply from Gilead and will sponsor the Phase 1 clinical combination trial evaluating ID397 and Trodelvy. Gilead will bear internal or external costs incurred in 
connection with its supply of Trodelvy. We will bear all internal and external costs and expenses associated with the conduct of the combination study. We and Gilead 
will jointly oversee clinical development of the combination therapy through a Joint Steering Committee responsible for coordinating all regulatory and other activities 
under the Gilead CSCSA. We and Gilead each retain commercial rights to our respective compounds, including with respect to use as a monotherapy agent or 
combination agent.

Adequate additional funding may not be available to us on acceptable terms or at all. See the section of this Annual Report on Form 10-K titled “Part I, Item 1A. – Risk 
Factors” for additional risks associated with our substantial capital requirements.

Off-Balance Sheet Arrangements

We have not entered into any off-balance sheet arrangements as defined in the rules and regulations of the SEC.

Net cash used in operating activities was $115.2 million for the year ended December 31, 2023. Cash used in operating activities was primarily due to the use of funds 
in our operations to develop our product candidates resulting in a net loss of $113.0 million, adjusted for net non-cash charges of $10.9 million and changes in net 
operating assets and liabilities of $13.2

 million. Our non-cash charges consisted of $18.5 million in stock-based compensation, and $2.5 million in depreciation and amortization of right of use asset of $1.5 
million, partially offset by $11.6 million accretion of discounts on marketable securities. The net change in our operating assets and liabilities consisted primarily of 
decreases of $13.8 million in contract liabilities due to revenue recognized under the GSK Collaboration Agreement, $2.0 million in prepaid and other assets, and $1.9 
million in lease liabilities, partially offset by $1.6 million accrued and other liabilities due to CRO fees in support of research and manufacturing activities, $2.6 million 
in accounts payable, and $0.2 million in accounts receivable from GSK for estimated program costs under the GSK Collaboration Agreement. 

Net cash used in operating activities was $87.2 million for the year ended December 31, 2022. Cash used in operating activities was primarily due to the use of funds in 
our operations to develop our product candidates resulting in a net loss of $58.7 million, adjusted for net non-cash charges of $14.4 million and changes in net operating 
assets and liabilities of $43.0 million. Our non-cash charges consisted of $11.6 million in stock-based compensation, and $2.1 million in depreciation, and $1.4 million 
of amortization of right of use asset, partially offset by $0.7 million accretion of discounts on marketable securities. The net change in our operating assets and liabilities 
consisted primarily of decreases of $46.5 million in contract liabilities due to revenue recognized under the GSK Collaboration Agreement, $2.1 million in prepaid and 
other assets, and $1.7 million in lease liabilities, partially offset by $4.6 million accrued and other liabilities due to CRO fees in support of research and manufacturing 
activities, $1.9 million in accounts payable, and $0.9 million in accounts receivable from GSK for estimated program costs under the GSK Collaboration Agreement. 

Cash Flows from Investing Activities 

Net cash used in investing activities was $158.5 million for the year ended December 31, 2023, which consisted primarily of $596.0 million used to purchase 
marketable securities and $2.4 million used to purchase property and equipment, partially offset by $439.9 million provided by maturities of marketable securities.

Net cash used in investing activities was $33.4 million for the year ended December 31, 2022, which consisted primarily of $255.8 million used to purchase marketable 
securities and $3.4 million used to purchase property and equipment, partially offset by $225.8 million provided by maturities of marketable securities. 

Cash Flows from Financing Activities 

Net cash provided by financing activities was $362.7 million for the year ended December 31, 2023, which consisted primarily of $281.2 million of net proceeds from 
our follow-on offering, $42.2 million of proceeds from issuance of pre-funded warrants, $28.6 million of proceeds from ATM offering, $9.6 million of proceeds from 
exercise of common stock options, and $1.2 million of proceeds from ESPP purchase.

Net cash provided by financing activities was $97.2 million for the year ended December 31, 2022, which consisted primarily of $86.1 million of net proceeds from our 
follow-on offering, $8.8 million of proceeds from ATM offering, $1.4 million of proceeds from exercise of common stock options, and $0.8 million of proceeds from 
ESPP purchase.

Critical Accounting Policies and Estimates 

Our financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements 
requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of 
the financial statements and the reported revenue recognized and expenses incurred during the reporting periods. Our estimates are based on our historical experience 
and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value 
of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We 
believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant 
areas involving management’s judgments and estimates. For more detail on our critical accounting policies, refer to Note 2 to the financial statements appearing 
elsewhere in this Annual Report on Form 10-K.

Revenue Recognition

Licenses of intellectual property: If a license to our intellectual property is determined to be distinct from the other promised goods or services identified in an 
arrangement, we recognize revenue from non-refundable, upfront fees allocated to the license at the point in time when the license is transferred to the customer and the 
customer is able to use and benefit from the license. For licenses that are bundled with other goods or services, we utilize judgment to assess the nature of the combined 
performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method 
of measuring progress toward satisfying the performance obligation for purposes of recognizing revenue from non-refundable, upfront fees. We evaluate the measure of 
progress each reporting period and, if necessary, adjust the measure of progress and related revenue recognition.

Customer options for additional goods or services: If a contract contains customer options that allow the customer to acquire additional goods or services, including a 
license to our intellectual property, the goods and services underlying the customer options are evaluated to determine whether they are deemed to represent a material 
right. In determining whether the customer option has a material right, we assess whether there is an option to acquire additional goods or services at a discount. If the 
customer option is determined not to represent a material right, the option is not considered to be a performance obligation. If the customer option is determined to 
represent a material right, the material right is recognized as a separate performance obligation. We allocate the transaction price to material rights based on the relative 
standalone selling price, which is determined based on the identified discount and the probability that the customer will exercise the option. Amounts allocated to a 
material right are not recognized as revenue until the option is exercised.

Milestone payments: At the inception of each arrangement or amendment that includes development, regulatory or commercial milestone payments, we evaluate 
whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price. ASC 606 prescribes two methods to 
use when estimating the amount of variable consideration: the expected value method and the most likely amount method. Under the expected value method, an entity 
considers the sum of probability-weighted amounts in a range of possible consideration amounts. Under the most likely amount method, an entity considers the single 
most likely amount in a range of possible consideration amounts. Whichever method is used, it should be consistently applied throughout the life of the contract; 
however, it is not necessary for us to use the same approach for all contracts. If it is probable that a significant revenue reversal would not occur when the uncertainty 
associated with the milestone is resolved, the associated milestone value is included in the transaction price. Milestone payments that are highly susceptible to factors 
outside our influence, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. If there is more than one 
performance obligation, the transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis. We recognize revenue as or 
when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, we re-evaluate the probability or achievement of each 
milestone and any related constraint, and if necessary, adjust our estimates of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up 
basis, which would affect revenues and earnings in the period of adjustment.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license deemed to be the predominant 
item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of 
the royalty has been allocated has been satisfied (or partially satisfied).

Upfront payments and fees are recorded as contract liabilities upon receipt or when due and may require deferral of revenue recognition to a future period until we 
perform our obligations under these arrangements. Amounts payable to us are recorded as accounts receivable when our right to consideration is unconditional. We do 
not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and 
the transfer of the promised goods or services to the customer will be one year or less.

Contractual cost sharing payments received from a customer or collaboration partner are accounted for as variable consideration. We include an expected value in the 
transaction price. Contractual cost sharing payments made to a customer or collaboration partner are accounted for as a reduction to the transaction price if such 
payments are not related to distinct goods or services received from the customer or collaboration partner.

Contracts may be amended to account for changes in contract specifications and requirements. Contract modifications exist when the amendment either creates new, or 
changes existing, enforceable rights and obligations. When contract modifications create new performance obligations and the increase in consideration approximates 
the standalone selling price for goods and services related to such new performance obligations as adjusted for specific facts and circumstances of the contract, the 
modification is accounted for as a separate contract. If a contract modification is not accounted for as a separate contract, we account for the promised goods or services 
not yet transferred at the date of the contract modification (the 

117

 
remaining promised goods or services) prospectively, as if it were a termination of the existing contract and the creation of a new contract, if the remaining goods or 
services are distinct from the goods or services transferred on or before the date of the contract modification. We account for a contract modification as if it were a part 
of the existing contract if the remaining goods or services are not distinct and, therefore, form part of a single performance obligation that is partially satisfied at the 
date of the contract modification. In such case the effect that the contract modification has on the transaction price, and on the entity’s measure of progress toward 
complete satisfaction of the performance obligation, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) at the date of the 
contract modification (the adjustment to revenue is made on a cumulative catch-up basis).

Upfront payment contract liabilities resulting from our license and collaboration agreements do not represent a financing component as the payment is not financing the 
transfer of goods and services, and the technology underlying the licenses granted reflects research and development expenses already incurred by us. As such, we do 
not adjust our revenues for the effects of a significant financing component.

Determination of the estimate of standalone selling price (SSP)

Prior to entering into the GSK Collaboration Agreement, we have never entered into a similar collaboration agreement nor have ever recognized any revenue, and the 
SSP of performance obligations identified in the GSK Collaboration Agreement is not directly observable. Accordingly, we developed an estimate of the SSP of each 
performance obligation based on the information known to us on the Effective Date and on input from an independent third-party valuation firm.

We applied the income approach as a primary methodology to determine the SSP of each performance obligation. Specifically, based on our early stage of development 
and other relevant factors, we determined to use the following methodologies:

(1)

(2)

(3)

(4)

(5)

(6)

Preclinical and Phase 1 Monotherapy clinical research and development services under the MAT2A program (MAT2A R&D Services) – the expected 
costs of satisfying the performance obligation, adjusted for probabilities of technical success where appropriate;

Preclinical research services and the related license to IDEAYA-owned technology under the Pol Theta program (Pol Theta R&D Services) – a 
combination of risk-adjusted net present value analysis and the expected costs of satisfying the performance obligation, adjusted for probabilities of 
technical success where appropriate;

Preclinical research services and the related license to IDEAYA-owned technology under the WRN program (WRN R&D Services) – a combination of 
risk-adjusted net present value analysis and the expected costs of satisfying the performance obligation, adjusted for probabilities of technical success 
where appropriate;

The Option – risk-adjusted net present value analysis;

Material right associated with the option to license to IDEAYA-owned technology under the MAT2A program to the extent necessary for preclinical 
activities in preparation for the MAT2A Combination Trial (Preclinical MAT2A License) – the expected costs of satisfying the performance obligation; 
and,

Material right associated with the supply of MAT2A product for the MAT2A Combination Trial (MAT2A Supply) – the expected costs of satisfying the 
performance obligation.

The assumptions used to determine the SSP of each performance obligation are based on numerous objective and subjective factors, combined with management 
judgment, including:

•

•

•

•

•

•

projected preclinical and clinical research and development expenses;

the probability of technical success for the development, regulatory approval and commercialization of our product candidates;

projected cash flow during development and commercialization periods;

discount rates based on cost of capital;

the probability of exercise of the Option; and,

the projected manufacturing cost and overhead expense for IDE 397.

We considered reasonably available data points, market conditions and entity-specific factors in estimating the SSP of performance obligations. However, some of these 
assumptions are specific to us and are not directly observable. We also applied our own judgment as management in determining these assumptions. Accordingly, these 
assumptions are subject to 

118

 
uncertainty, and changing methodology and/or assumption could materially impact the estimate of the SSP of performance obligations, and as a result, an amount of 
subsequent revenue recognition and/or its timing.

Determination of the timing of satisfaction of performance obligations

We recognize revenue from the MAT2A R&D Services, Pol Theta R&D Services and WRN R&D Services over time, as GSK simultaneously receives and consumes 
the benefits provided by our performance as we perform. We measure our progress toward complete satisfaction of the MAT2A R&D Services, Pol Theta R&D 
Services and WRN R&D Services based on the costs incurred as a percentage of the estimated total costs to be incurred to complete the performance obligations.

The estimated total costs to be incurred to complete the MAT2A R&D Services, Pol Theta R&D Services and WRN R&D Services may evolve and be updated 
throughout the performance period with the consultation with GSK through the joint development committee. The change in the estimated total costs and/or the timing 
of completion may materially impact an amount of subsequent revenue recognition and/or its timing. MAT2A R&D Services and Pol Theta R&D Services are 
completed. The expected timing of completing the WRN R&D Services may be updated. 

JOBS Act Accounting Election

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, permits an “emerging growth company” which we were until December 31, 2023 to take advantage 
of an extended transition period to comply with new or revised accounting standards applicable to public companies. As of June 30, 2023, the aggregate market value of 
the voting and non-voting common equity held by non-affiliates was $1.3 billion, and we are deemed a large accelerated filer as of January 1, 2024, commencing with 
this Annual Report on Form 10-K for the year ending December 31, 2023. As a result, we are ceased to be an emerging growth company as of December 31, 2023.

Recent Accounting Pronouncements

this Annual Report on Form 10-K for additional information.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Sensitivity

The market risk inherent in our financial instruments and in our financial position represents the potential loss arising from adverse changes in interest rates or exchange 
rates. As of December 31, 2023, we had cash equivalents and marketable securities of $632.6 million, consisting of interest-bearing money market funds, investments 
in U.S. government securities, commercial paper, and corporate bonds, for which the fair value would be affected by changes in the general level of U.S. interest rates. 
Even if the fair value of certain government securities, commercial paper, and corporate bonds is affected by changes in U.S. interest rates, the principal of such 
instruments will be due to us upon maturity. 

While we are seeing, and expect to continue to see, record inflation and elevated interest rates due to geopolitical and macroeconomic events, such as the ongoing 
Ukraine-Russia conflict and related sanctions, the Israel-Hamas conflict, and the banking sector volatility, we do not believe that inflation, interest rate changes or 
exchange rate fluctuations have had a significant impact on our results of operations for any periods presented herein.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the 
Exchange Act, that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, 
processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and (2) accumulated and 
communicated to our management, including our principal executive officer and principal financial and accounting officer, as appropriate to allow timely decisions 
regarding required disclosure. Our management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only 
reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible disclosure 
controls and procedures. 

Our management, with the participation of our principal executive officer and principal financial and accounting officer, evaluated the effectiveness of our disclosure 
controls and procedures at the end of the period covered by this Annual Report on Form 10-K. Based upon such evaluation, our principal executive officer and principal 
financial and accounting officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of such date.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company's internal control over financial reporting that occurred during the quarter ended December 31, 2023 that have materially 
affected, or are reasonably likely to materially effect, the Company's internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange 
Act). Under the supervision of and with the participation of our principal executive officer and principal financial and accounting officer, our management assessed the 
effectiveness of our internal control over financial reporting as of December 31, 2023 based on the criteria set forth by the Committee of Sponsoring Organizations of 
the Treadway Commission in “Internal Control—Integrated Framework” (2013). Based on this assessment, management concluded that our internal control over 
financial reporting was effective as of December 31, 2023.

The effectiveness of our internal control over financial reporting as of December 31, 2023 has been audited by PricewaterhouseCoopers LLP, an independent registered 
public accounting firm, as stated in their report, which is included under “Item 8. Financial Statements and Supplementary Data” of this Annual Report.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of IDEAYA Biosciences, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying balance sheets of IDEAYA Biosciences, Inc. (the “Company”) as of December 31, 2023 and 2022, and the related statements of 
operations and comprehensive loss, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related 
notes (collectively referred to as the “financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2023, 
based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 
2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles 
generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework(2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of 
the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. 
Our responsibility is to express opinions on the Company’s financial statements and on the Company's internal control over financial reporting based on our audits. We 
are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect 
to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the 
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance 
about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting 
was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or 
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in 
the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 
overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over 
financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a 
reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the 
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial 
reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

F-2

 
 
 
 
 
 
 
 
 
 
 
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness 
to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or 
procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be 
communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the financial statements and (ii) involved our especially 
challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a 
whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to 
which it relates. 

Accrued Research and Development Expenses Related to Contract Research Organizations 

As described in Notes 2 and 4 to the financial statements, the Company has entered into various agreements with contract research organizations (CROs). The 
Company’s accrued research and development expenses as of December 31, 2023 was $10.7 million, of which a portion relates to open agreements with CROs. The 
Company’s research and development accruals are estimated based on the level of services performed, progress of the studies, including the phase or completion of 
events, and contracted costs. The estimated costs of research and development provided, but not yet invoiced, are included in accrued liabilities on the balance sheet. If 
the actual timing of the performance of services or the level of effort varies from the original estimates, management will adjust the accrual accordingly. Management’s 
process involves reviewing open contracts and purchase orders, communicating with applicable personnel to identify services that have been performed, and estimating 
the level of service performed and the associated costs incurred based on vendor estimates for the services when the Company has not yet been invoiced or otherwise 
notified of actual costs. 

The principal consideration for our determination that performing procedures relating to accrued research and development expenses related to CROs is a critical audit 
matter is a high degree of auditor effort in performing procedures related to the Company’s accrued research and development expenses related to CROs. 

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the financial statements. These 
procedures included testing the effectiveness of controls relating to accrued research and development expenses, including controls related open agreements with CROs. 
These procedures also included, among others, testing research and development expenses related to CROs, on a sample basis, by obtaining and inspecting source 
documents, such as underlying agreements with CROs, purchase orders, invoices received, and information received from certain third party service providers.

1. Organization

Description of the Business 

IDEAYA Biosciences, Inc.

IDEAYA Biosciences, Inc. (the “Company”) is a synthetic lethality-focused precision medicine oncology company committed to the discovery and development of 
targeted therapeutics for patient populations selected using molecular diagnostics. The Company is headquartered in South San Francisco, California and was 
incorporated in the State of Delaware in June 2015. To date, the Company has been primarily engaged in business planning, research, development, recruiting and 
raising capital. 

Follow-On Offering

On September 19, 2022, we completed an underwritten public offering of 8,761,905 shares of our common stock at an offering price to the public of $10.50 per share, 
including 1,142,857 shares of common stock upon the exercise in full of the overallotment option by the underwriters, pursuant to which we received aggregate net 
proceeds of $86.1 million, after deducting underwriting discounts and commissions and other offering expenses. 

On April 27, 2023, the Company completed an underwritten public follow-on offering. The offering consisted of 8,858,121 shares of our common stock at an offering 
price to the public of $18.50 per share, including 1,418,920 shares of common stock upon the exercise in full of the overallotment option by the underwriters, as well as 
pre-funded warrants to purchase 2,020,270 shares of common stock at a public offering price of $18.4999 per underlying share, in each case before underwriting 
discounts and commissions. Pursuant to the offering, we received aggregate gross proceeds of approximately $201.3 million, before deducting underwriting discounts 
and commissions and other offering expenses, resulting in net proceeds of approximately $188.7 million, after deducting underwriting discounts and commissions and 
other offering expenses.

On October 27, 2023, the Company completed a further underwritten public follow-on offering. The offering consisted of 5,797,872 shares of our common stock at an 
offering price to the public of $23.50 per share, including 797,872 shares of common stock upon the exercise in full of the overallotment option by the underwriters, as 
well as pre-funded warrants to purchase 319,150 shares of common stock at a public offering price of $23.4999 per underlying share, in each case before underwriting 
discounts and commissions. Pursuant to the offering, we received aggregate gross proceeds of approximately $143.7 million, before deducting underwriting discounts 
and commissions and other offering expenses, resulting in net proceeds of approximately $134.6 million, after deducting underwriting discounts and commissions and 
other offering expenses.

At-the-Market Offering

Our Registration Statement on Form S-3, which was filed under the Securities Act, and became effective as of June 10, 2020, lapsed in June 2023. The January 2021 
Sales Agreement was automatically terminated concurrently therewith. As of the termination date of the January 2021 Sales Agreement, approximately $61.8 million of 
common stock remained available to be sold under the at-the-market facility associated therewith.

On June 26, 2023, we filed a new Registration Statement on Form S-3 (File No. 333- 272936) under the Securities Act as an automatic shelf registration statement as a 
“well-known seasoned issuer”, as defined in Rule 405 under the Securities Act. On June 26, 2023, we also entered into a new Open Market Sales Agreement, or June 
2023 Sales Agreement, with Jefferies LLC (“Jefferies”) relating to an at-the-market offering program under which we may offer and sell, from time to time at our sole 
discretion, shares of our common stock, par value $0.0001 per share, having aggregate gross proceeds of up to $250.0 million through Jefferies as sales agent.

During the year ended December 31, 2023, we sold an aggregate of 1,188,705 shares of our common stock through at-the-market offerings for aggregate net proceeds 
of $28.6 million, after deducting underwriting discounts and commissions and other offering expenses, at a weighted average sales price of approximately $25.30 per 
share under the at-the-market offering pursuant to the January 2021 Sales Agreement and June 2023 Sales Agreement with Jefferies as sales agent. As of December 31, 
2023, approximately $222.5 million of common stock remained available to be sold under the June 2023 Sales Agreement with Jefferies as sales agent.

Liquidity 

The Company has incurred significant losses and negative cash flows from operations in all periods since inception and had an accumulated deficit of $348.4 million as 
of December 31, 2023. 

The Company has historically financed its operations primarily through the sale of convertible notes, redeemable convertible preferred stock and common stock, pre-
funded warrants, and payments received from its collaboration arrangement. 

To date, none of the Company’s product candidates have been approved for sale, and the Company has not generated any revenue from commercial products since 
inception. Management expects operating losses to continue and increase for the foreseeable future, as the Company progresses into clinical development activities for 
its lead product candidates. The Company’s prospects are subject to risks, expenses and uncertainties frequently encountered by companies in the biotechnology 
industry as discussed under Risks and Uncertainties in Note 2. While the Company has been able to raise multiple rounds of financing, there can be no assurance that in 
the event the Company requires additional financing, such financing will be available on terms which are favorable or at all. Failure to generate sufficient cash flows 
from operations, raise additional capital or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended 
business objectives. 

As of December 31, 2023, the Company had cash, cash equivalents and marketable securities of $632.6 million. Management believes that the Company’s current cash, 
cash equivalents and marketable securities will be sufficient to fund its planned operations for at least 12 months from the date of the issuance of these financial 
statements.

2. Summary of Significant Accounting Policies

Basis of Presentation

The financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America 
(“U.S. GAAP”).

Use of Estimates 

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of 
assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during 
the reporting period. Such estimates include useful lives of property and equipment, determination of the discount rate for operating leases, accruals for research and 
development activities, revenue recognition, stock-based compensation, and income taxes. On an ongoing basis, management reviews these estimates and assumptions. 
Changes in facts and circumstances may alter such estimates and actual results could differ from those estimates.

Segments 

The Company operates and manages its business as one operating and reportable segment, which is the business of research and development for oncology-focused 
precision medicine. The Company’s chief executive officer, who is the chief operating decision maker, reviews financial information on an aggregate basis for purposes 
of allocating resources and evaluating financial performance. All of the Company's long-lived assets are located in the United States.

Risks and Uncertainties 

The Company operates in a dynamic and highly competitive industry and is subject to risks and uncertainties common to early-stage companies in the biotechnology 
industry, including, but not limited to, development by competitors of new technological innovations, protection of proprietary technology, dependence on key 
personnel, contract manufacturers, contract research organizations and collaboration partners, compliance with government regulations and the need to obtain additional 
financing to fund operations. Product candidates currently under development will require significant additional research and development efforts, including extensive 
preclinical studies and clinical trials and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate 
personnel infrastructure and extensive compliance and reporting. The Company believes that changes in any of the following areas could have a material adverse effect 
on the Company’s future financial position, results of operations, or cash flows: ability to obtain future financing; advances and trends in new technologies and industry 
standards; results of clinical trials and collaboration activities; regulatory approval and market acceptance of the Company’s products; development of sales channels; 
certain strategic relationships; litigation or claims against the Company based on intellectual property, patent, product, regulatory, or other factors; and the Company’s 
ability to attract and retain employees necessary to support its growth. 

F-9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Products developed by the Company require approvals from the U.S. Food and Drug Administration (“FDA”) or other international regulatory agencies prior to 
commercial sales. There can be no assurance that the Company’s research and development will be successfully completed, that adequate protection for the Company’s 
intellectual property will be obtained or maintained, that the products will receive the necessary approvals, or that any approved products will be commercially viable. If 
the Company was denied approval, approval was delayed or the Company was unable to maintain approval, it could have a materially adverse impact on the Company. 
Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will generate revenue from product sales. The Company 
operates in an environment of rapid change in technology and substantial competition from other pharmaceutical and biotechnology companies. In addition, the 
Company is dependent upon the services of its employees, consultants and other third parties.

The Company has expended and will continue to expend substantial funds to complete the research, development and clinical testing of product candidates. The 
Company also will be required to expend additional funds to establish commercial-scale manufacturing arrangements and to provide for the marketing and distribution 
of products that receive regulatory approval. The Company may require additional funds to commercialize its products. The Company is unable to entirely fund these 
efforts with its current financial resources. If adequate funds are unavailable on a timely basis from operations or additional sources of financing, the Company may 
have to delay, reduce the scope of or eliminate one or more of its research or development programs which would materially and adversely affect its business, financial 
condition and operations. 

Concentration of Credit Risk 

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and marketable securities. Substantially all 
the Company’s cash is held by two financial institutions that management believes are of high credit quality. Such deposits may, at times, exceed federally insured 
limits. 

The Company’s investment policy addresses credit ratings, diversification, and maturity dates. The Company invests its cash equivalents and marketable securities in 
money market funds, U.S. government securities, commercial paper, and corporate bonds. The Company limits its credit risk associated with cash equivalents and 
marketable securities by placing them with banks and institutions it believes are creditworthy and in highly rated investments and, by policy, limits the amount of credit 
exposure with any one commercial issuer. The Company has not experienced any credit losses on its deposits of cash, cash equivalents or marketable securities. 

Cash Equivalents 

Cash equivalents that are readily convertible to cash are stated at cost, which approximates fair value. The Company considers all highly liquid investments purchased 
with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. 

Restricted Cash 

Restricted cash as of December 31, 2023 and December 31, 2022 consisted of cash balances held as security in connection with the Company’s facility lease 
agreements in South San Francisco, California and San Diego, California. The balances are classified as long-term assets on the Company’s balance sheet.

Marketable Securities 

Marketable securities are investments in marketable securities with maturities greater than three months at the time of purchase. The Company determines the 
appropriate classification of its investments in marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. The Company 
has classified and accounted for its marketable securities as available-for-sale. After consideration of the Company’s risk versus reward objectives and liquidity 
requirements, the Company may sell these securities prior to their stated maturities. The Company classifies highly liquid securities with maturities beyond 12 months 
as long-term marketable securities in the balance sheet. These securities are carried at fair value as determined based upon quoted market prices or pricing models for 
similar securities. Unrealized gains and losses, if any, are excluded from earnings and are reported as a component of accumulated other comprehensive income (loss). 
The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity, which is included in interest income and other 
income (expense), net on the statements of operations and comprehensive loss. Realized gains and losses, if any, on available-for-sale securities are included in interest 
income and other income (expense), net. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as 
available-for-sale are included in interest income. 

F-10

 
Fair Value of Financial Instruments 

The carrying amounts of the Company’s certain financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued liabilities 
approximate fair value due to their relatively short maturities and market interest rates if applicable. Refer to Note 3 for details on the fair value of marketable securities. 

Property and Equipment, Net 

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated 
useful lives of the assets, which is generally between three and five years. Leasehold improvements are stated at cost and amortized over the shorter of the useful lives 
of the assets or the lease term. Maintenance and repairs are charged to expense as incurred. When assets are retired or otherwise disposed of, the cost and accumulated 
depreciation are removed from the balance sheet and any resulting gain or loss is reflected in the statements of operations and comprehensive loss in the period realized. 

Impairment of Long-Lived Assets 

The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group 
may not be recoverable. Recoverability is measured by comparison of the carrying amount of the asset or asset group to the future net cash flows which the asset or 
asset group is expected to generate. If such asset or asset group is considered to be impaired, the impairment to be recognized is measured by the amount by which the 
carrying amount of the asset or asset group exceeds the fair value of the asset or asset group. There have been no such impairments of long-lived assets for the years 
ended December 31, 2023 and December 31, 2022. 

Leases 

The Company determines if an arrangement is a lease, or contains a lease, at its inception. Operating leases are included in right-of-use (“ROU”) assets, lease liabilities, 
and long-term lease liabilities on the Company’s balance sheet.

ROU assets and lease liabilities are recognized based on the present value of the future lease payments over the lease term at commencement date. As most of the 
Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in 
determining the present value of future payments. The ROU asset also includes any lease payments made to the lessor at or before the commencement date, minus lease 
incentives received, and initial direct costs incurred. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that 
the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company combines lease and 
nonlease components.

Cloud Computing Arrangements

The Company capitalizes certain implementation costs incurred under a cloud computing arrangement that is a service contract. Costs incurred during the application 
development stage related to the implementation of the hosting arrangement are capitalized and included within prepaid expenses and other current assets, and other 
non-current assets on the accompanying balance sheets. Amortization of capitalized implementation costs is recognized on a straight-line basis over the term of the 
associated hosting arrangement when it is ready for its intended use. Costs related to preliminary project activities and post-implementation activities are expensed as 
incurred.

Revenue Recognition

The Company follows Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, the Company recognizes 
revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in 
exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company 
performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction 
price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance 
obligation. 

The Company applies the five-step model to contracts when (1) parties have approved the contract and are committed to performing respective obligations, (2) the 
Company can identify each party’s rights regarding the goods or services to be transferred, (3) the Company can identify the payment terms for the goods or services to 
be transferred, (4) the contract has commercial substance, and (5) it is probable that the Company will collect the consideration it is entitled to in exchange for 

F-11

 
the goods or services it transfers to the customer. At contract inception, the Company assesses the goods or services promised within each contract and determines the 
performance obligations by assessing whether each promised good or service is distinct. Goods or services that are not distinct are bundled with other goods or services 
in the contract until a bundle of goods or services that is distinct is created. The Company then recognizes as revenue the amount of the transaction price that is 
allocated to the respective performance obligations when (or as) the performance obligations are satisfied. The Company constrains its estimate of the transaction price 
up to the amount (the “variable consideration constraint”) that a significant reversal of recognized revenue is not probable.

Licenses of intellectual property: If a license to the Company’s intellectual property is determined to be distinct from the other promised goods or services identified in 
an arrangement, the Company recognizes revenue from non-refundable, upfront fees allocated to the license at the point in time when the license is transferred to the 
customer and the customer is able to use and benefit from the license. For licenses that are bundled with other goods or services, the Company applies judgment to 
assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if 
over time, the appropriate method of measuring progress toward satisfying the performance obligation for purposes of recognizing revenue from non-refundable, 
upfront fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of progress and related revenue recognition.

Customer options for additional goods or services: If a contract contains customer options that allow the customer to acquire additional goods or services, including a 
license to the Company’s intellectual property, the goods and services underlying the customer options are evaluated to determine whether they are deemed to represent 
a material right. In determining whether the customer option has a material right, the Company assesses whether there is an option to acquire additional goods or 
services at a discount. If the customer option is determined not to represent a material right, the option is not considered to be a performance obligation. If the customer 
option is determined to represent a material right, the material right is recognized as a separate performance obligation. The Company allocates the transaction price to 
material rights based on the relative standalone selling price, which is determined based on the identified discount and the probability that the customer will exercise the 
option. Amounts allocated to a material right are not recognized as revenue until the option is exercised.

Milestone payments: At the inception of each arrangement or amendment that includes development, regulatory or commercial milestone payments, the Company 
evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price. ASC 606 prescribes two 
methods to use when estimating the amount of variable consideration: the expected value method and the most likely amount method. Under the expected value 
method, an entity considers the sum of probability-weighted amounts in a range of possible consideration amounts. Under the most likely amount method, an entity 
considers the single most likely amount in a range of possible consideration amounts. The Company uses the expected value method to estimate the amount of variable 
consideration related to the reimbursement of Pol Theta and WRN program costs which is consistently applied throughout the life of the contract: however, it is not 
necessary for the Company to use the same approach for all contracts. If it is probable that a significant revenue reversal would not occur when the uncertainty 
associated with the milestone is resolved, the associated milestone value is included in the transaction price. Milestone payments that are highly susceptible to factors 
outside the Company’s influence, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. If there is more than 
one performance obligation, the transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis. The Company recognizes 
revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the 
probability or achievement of each milestone and any related constraint, and if necessary, adjusts its estimates of the overall transaction price. Any such adjustments are 
recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license deemed to be the predominant 
item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which 
some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Upfront payments and fees are recorded as contract liabilities upon receipt or when due and may require deferral of revenue recognition to a future period until the 
Company performs its obligations under these arrangements. Amounts payable to the Company are recorded as accounts receivable when the Company’s right to 
consideration is unconditional. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such 
that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less.

Contractual cost sharing payments received from a customer or collaboration partner are accounted for as variable consideration. The Company includes an expected 
value in the transaction price. Contractual cost sharing payments made to a customer or collaboration partner are accounted for as a reduction to the transaction price if 
such payments are not related to distinct goods or services received from the customer or collaboration partner.

Contracts may be amended to account for changes in contract specifications and requirements. Contract modifications exist when the amendment either creates new, or 
changes existing, enforceable rights and obligations. When contract 

F-12

 
modifications create new performance obligations and the increase in consideration approximates the standalone selling price for goods and services related to such new 
performance obligations as adjusted for specific facts and circumstances of the contract, the modification is accounted for as a separate contract. If a contract 
modification is not accounted for as a separate contract, the Company accounts for the promised goods or services not yet transferred at the date of the contract 
modification (the remaining promised goods or services) prospectively, as if it were a termination of the existing contract and the creation of a new contract, if the 
remaining goods or services are distinct from the goods or services transferred on or before the date of the contract modification. The Company accounts for a contract 
modification as if it were a part of the existing contract if the remaining goods or services are not distinct and, therefore, form part of a single performance obligation 
that is partially satisfied at the date of the contract modification. In such case, the effect that the contract modification has on the transaction price, and on the entity’s 
measure of progress toward complete satisfaction of the performance obligation, is recognized as an adjustment to revenue (either as an increase in or a reduction of 
revenue) at the date of the contract modification (the adjustment to revenue is made on a cumulative catch-up basis).

Upfront payment contract liabilities resulting from the Company’s license and collaboration agreements do not represent a financing component as the payment is not 
financing the transfer of goods and services, and the technology underlying the licenses granted reflects research and development expenses already incurred by the 
Company. As such, the Company does not adjust its revenues for the effects of a significant financing component. Amounts received prior to satisfying the revenue 
recognition criteria are recorded as contract liability in the Company’s balance sheets. If the related performance obligation is expected to be satisfied within the next 
twelve (12) months, this will be classified and included within current contract liability.

Research and Development Expenses 

Research and development expenses consist of compensation costs, employee benefit costs, costs for contract manufacturing organizations (“CMOs”), costs for contract 
research organizations (“CROs”), costs for clinical trials, costs for sponsored research, consulting costs, costs for laboratory supplies, costs for product licenses, facility-
related expenses and depreciation. All research and development costs are charged to research and development expenses as incurred and included within the statements 
of operations and comprehensive loss. Payments associated with licensing agreements to acquire exclusive licenses to develop, use, manufacture and commercialize 
products that have not reached technological feasibility and do not have alternate commercial use are also expensed as incurred. Payments made to third parties under 
these arrangements in advance of the performance of the related services by the third parties are recorded as prepaid expenses until the services are rendered.

Accrued Research and Development Expenses

The Company has entered into various agreements with CMOs and CROs. The Company’s research and development accruals are estimated based on the level of 
services performed, progress of the studies, including the phase or completion of events, and contracted costs. The estimated costs of research and development 
provided, but not yet invoiced, are included in accrued liabilities on the balance sheet. If the actual timing of the performance of services or the level of effort varies 
from the original estimates, the Company will adjust the accrual accordingly. Payments made to CMOs and CROs under these arrangements in advance of the 
performance of the related services are recorded as prepaid expenses and other current assets until the services are rendered. Management’s process involves reviewing 
open contracts and purchase orders, communicating with applicable personnel to identify services that have been performed, and estimating the level of service 
performed and the associated costs incurred based on vendor estimates for the services when the Company has not yet been invoiced or otherwise notified of actual 
costs. 

Stock-Based Compensation 

The Company accounts for stock-based compensation arrangements with employees and non-employees in accordance with ASC 718, Stock Compensation. The 
Company accounts for stock-based compensation arrangements using a fair value method which requires the recognition of compensation expense related to all stock-
based awards. The fair value method requires the Company to estimate the fair value of stock option awards on the date of grant using an option pricing model. The 
Company uses the Black-Scholes option pricing model to determine the fair value of options granted, which is expensed on a straight-line basis over the vesting period. 
Generally, the stock options granted by the Company to its employees have a 10-year term and vest over a 4-year period with 1-year cliff vesting.

Income Taxes 

The Company accounts for income taxes using the asset and liability method whereby deferred tax assets and liabilities are determined based on differences between 
financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are currently in effect unless such rate is expected to 
be different when the deferred item 

F-13

 
reverses. Valuation allowances are established where necessary to reduce deferred tax assets to the amounts expected to be realized. Deferred tax assets and liabilities 
are classified as noncurrent on the balance sheet. 

The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are 
measured at the largest amount that has a greater than 50% likelihood of being realized. Changes in recognition or measurement are reflected in the period in which the 
change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in interest expense and other expense, respectively.

Comprehensive Loss 

Comprehensive loss includes net loss and certain changes in stockholders’ equity that are excluded from net loss, primarily unrealized gains and losses from the 
Company’s marketable securities.

Net Loss per Share Attributable to Common Stockholders 

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common stock 
outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to 
common stockholders by the weighted-average number of common stock and potentially dilutive securities outstanding for the period. Pre-funded warrants are included 
in the calculation of basic and diluted earnings per share. For purposes of the diluted net loss per share calculation, stock options, restricted stock and restricted stock 
that is subject to repurchase at the original purchase price are considered to be potentially dilutive securities. The Company considers the shares issued upon the early 
exercise of stock options subject to repurchase to be participating securities, because holders of such shares have non-forfeitable dividend rights in the event a dividend 
is paid on common stock. The holders of early exercised shares subject to repurchase do not have a contractual obligation to share in the Company’s losses. As such, the 
net loss was attributed entirely to common stockholders. Because the Company has reported a net loss for all periods presented, diluted net loss per common share is the 
same as basic net loss per common share for those periods. 

Recent Accounting Pronouncements 

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) under its accounting standard codifications 
(“ASC”) or other standard setting bodies and adopted by the Company as of the specified effective date, unless otherwise discussed below. 

New Accounting Pronouncements Adopted 

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which 
requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss 
impairment model with an expected loss model. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale 
debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in 
earlier recognition of credit losses. For public business entities, this ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within 
those fiscal years. The FASB subsequently issued supplemental guidance to ASC 326 within ASU 2019-05, Financial Instruments—Credit Losses (Topic 326): 
Targeted Transition Relief, ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) and ASU 
2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses. ASU 2019-05 provides an option to irrevocably elect the fair value option for 
certain financial assets previously measured at amortized cost basis. ASU 2019-10 extended the effectiveness of Topic 326 for smaller reporting companies until fiscal 
years beginning after December 15, 2022. As of January 1, 2024, the Company is no longer a smaller reporting company. The Company adopted this ASU on January 
1, 2023, and evaluated the impact of the adoption of the ASU. It did not result in a material impact on the Company's financial statements and related disclosures. 

New Accounting Pronouncements Issued, Not yet Adopted

On October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification 
Initiative, which modifies the disclosure or presentation requirements related to variety of FASB Accounting Standard Codification topics. The effective date for each 
amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K is effective. If by June 30, 2027, the SEC has 
not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the associated amendment will be removed from the 
Codification and will not become effective for any entities. We are currently evaluating the effect of adopting this ASU.

F-14

 
 
 
On December 14, 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which amends the guidance in ASC 740, Income Taxes. The ASU is 
intended to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation 
and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The ASU’s 
amendments are effective for public business entities for annual periods beginning after December 15, 2024. Entities are permitted to early adopt the standard “for 
annual financial statements that have not yet been issued or made available for issuance.” Adoption is either prospectively or retrospectively, the Company will adopt 
this ASU on a prospective basis. The Company is currently evaluating the impact of the ASU but does not expect any material impacts upon adoption. 

3. Fair Value Measurement and Marketable Securities

The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in 
the financial statements on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an 
orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market 
participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which 
prioritizes the inputs used in measuring fair value as follows: 

Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities at the measurement date. 

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other 
inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. 

Level 3—Unobservable inputs which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the 
measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. 

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the 
extent possible as well as considers counterparty credit risk in its assessment of fair value.

As of December 31, 2023, financial assets measured and recorded at fair value are as follows (in thousands):

$4.0 million was included in cash and cash equivalents on the balance sheet due to securities with purchase dates within 90 days of maturity dates
Included in cash and cash equivalents on the balance sheet

As of December 31, 2023 and December 31, 2022, all marketable securities had a remaining maturity of less than two years. There were no financial liabilities 
measured and recognized at fair value as of December 31, 2023 and December 31, 2022.

The Company considers available evidence in evaluating potential other-than-temporary impairments of its marketable securities, including the duration and extent to 
which fair value is less than cost, and the Company’s ability and intent to hold the investment. As of December 31, 2023 and December 31, 2022, the Company held 
certain securities in an unrealized loss position. These unrealized losses were considered to be temporary as the Company expects to recover the entire amortized cost 
basis on the securities in unrealized loss positions based on the creditworthiness of the underlying issuer, and the Company neither intends to sell these securities nor 
considers it more likely than not that the Company would be required to sell any such security before its anticipated recovery. As a result, the Company did not consider 
any of these investments to be other-than-temporarily impaired at December 31, 2023 and December 31, 2022.

5. Operating Leases

The Company leases its laboratory and office facilities in South San Francisco for approximately 29,000 square feet with an expiration date in July 2024.

In June 2023, we entered into a lease agreement for approximately 44,000 square feet of space at 5000 Shoreline Court, South San Francisco, California. The estimated 
commencement date is June 2024 and the lease term is one hundred twenty months. The Company has the option to extend the lease term for two consecutive five-year 
periods. 

In November 2023, we entered into a lease agreement for approximately 5,700 square feet of space at 11710 El Camino Real, San Diego, California for corporate office 
space. The lease commenced in December 2023 and expires in March 2028. We have an option to renew the lease for 3 years. The Company recorded a right-of-use 
asset and lease liability related to the lease upon its commencement date in December 2023. As of December 31, 2023, the balances of the right-of-use asset and the 
lease liability were $1.3 million each.

Future minimum lease payments under operating leases included on the Company's balance sheet are as follows:

Operating lease costs were $1.7 million for each of the years ended December 31, 2023, 2022 and 2021. Variable lease costs were $1.4 million, $1.0 million, and $1.0 
million for the years ended December 31, 2023, 2022, and 2021, respectively. Variable lease costs represent additional costs incurred, related to administration, 
maintenance and property tax costs incurred, which are billed based on both usage and as a percentage of the Company's share of total square footage.

During the years ended December 31, 2023, 2022 and 2021, cash paid for amounts included in the measurement of lease liabilities and included within cash used in 
operating activities in the statement of cash flows was $2.0 million, $2.0 million and $1.9 million, respectively.

Contingencies 

From time to time, the Company may be involved in litigation related to claims that arise in the ordinary course of its business activities. The Company accrues for 
these matters when it is probable that future expenditures will be made and these expenditures can be reasonably estimated. As of December 31, 2023, the Company 
does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s financial position, results of operations or 
cash flows.

Indemnification 

The Company enters into standard indemnification arrangements in the ordinary course of business with vendors, clinical trial sites and other parties. Pursuant to these 
arrangements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party. The 
term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments the 
Company could be required to make under these arrangements is not determinable. The Company has never incurred costs to defend lawsuits or settle claims related to 
these indemnification agreements. Accordingly, the Company has not recorded a liability related to such indemnification agreements as of December 31, 2023.

7. Income Taxes

No provision for income taxes was recorded for the years ended December 31, 2023, December 31, 2022 and December 31, 2021. The Company has incurred net 
operating losses only in the United States since its inception. The Company has not reflected any benefit of such net operating loss carryforwards in the financial 
statements. 

The provision for income taxes differs from the amount expected by applying the federal statutory rate to the loss before taxes as follows:

The Company has established a full valuation allowance against its deferred tax assets due to the uncertainty surrounding the realization of such assets. 

ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management 
assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income 
within the carryforward period. Because of the Company’s recent history of operating losses, management believes that recognition of the deferred tax assets arising 
from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a valuation allowance. 

As of December 31, 2023, the Company had net operating loss carryforwards of $135.3 million available to reduce future taxable income, if any, for federal income tax 
purposes. As of December 31, 2023, the Company had net operating loss carryforwards of $89.6 million available to reduce future taxable income, if any, for state 
income tax purposes. If not utilized, the federal carryforwards of $11.6 million and the state carryforwards of $89.6 million will begin to expire in 2037 and 2036, 
respectively. The federal net operating loss carryforwards of $123.7 million arising after December 31, 2017 do not expire. 

The Company also had federal and state research and development credit carryforwards of $12.0 million and $6.4 million, respectively. The Company also had Orphan 
Drug Credits, or ODC, related to the orphan drug designation of darovasertib in 2022, of $6.3 million. The federal credits will expire starting in 2037 if not utilized, and 
the state research credit can be carried forward indefinitely. 

The Tax Reform Act of 1986 limits the use of net operating loss carryforwards in certain situations where changes occur in the stock ownership of a company. The 
annual limitation may result in the expiration of net operating losses and credits before utilization. The Company performed a Section 382 analysis through December 
31, 2023. The Company has not experienced ownership changes in the current year. Subsequent ownership changes may affect the limitation in future years. 

Related to unrecognized tax benefits noted below, the Company accrued no penalties or interest during the years ended December 31, 2023, December 31, 2022 and 
December 31, 2021. The Company does not expect its unrecognized tax benefit balance to change materially over the next 12 months. 

The Company had $3.8 million and $2.0 million of unrecognized tax benefits as of December 31, 2023 and December 31, 2022, respectively.

The following table summarizes the activity related to the Company’s unrecognized tax benefits (in thousands).

The Company files income tax returns in the U.S. federal jurisdiction and in the state of Arizona, California, New Jersey, Wisconsin, North Carolina and Pennsylvania. 
For jurisdictions in which tax filings have been filed, all tax years remain open for examination by the federal and state authorities for three and four years, respectively, 
from the date of utilization of any net operating losses or credits.

The Inflation Reduction Act was signed into law on August 16, 2022, and contained several tax provisions to curb inflation by reducing the deficit, lowering 
prescription drug prices, investing into domestic energy production while promoting clean energy, and introduced the topic of corporate alternative minimum tax on 
applicable corporations. There is no impact to the Company’s current tax provision.

In accordance with the 2017 Tax Act, research and experimental (R&E) expenses under Internal Revenue Code Section 174 are required to be capitalized beginning in 
2022. R&E expenses are required to be amortized over a period of 5 years for domestic expenses and 15 years for foreign expenses. The Company has reflected this in 
its current tax provision.

8. Common Stock

As of December 31, 2023 and December 31, 2022, the Company’s certificate of incorporation authorized the Company to issue 300,000,000 shares of common stock at 
a par value of $0.0001 per share. Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever 
funds are legally available and when declared by the Company’s board of directors. As of December 31, 2023, no dividends have been declared to date. 

On October 27, 2023, the Company completed a further underwritten public follow-on offering. The offering consisted of 5,797,872 shares of our common stock at an 
offering price to the public of $23.50 per share, including 797,872 shares of common stock upon the exercise in full of the overallotment option by the underwriters, as 
well as pre-funded warrants to purchase 319,150 shares of common stock at a public offering price of $23.4999 per underlying share, in each case before underwriting 
discounts and commissions. Pursuant to the offering, we received aggregate gross proceeds of approximately $143.7 million, before deducting underwriting discounts 
and commissions and other offering expenses, resulting in net proceeds of approximately $134.6 million, after deducting underwriting discounts and commissions and 
other offering expenses. 

On April 27, 2023, the Company completed an underwritten public follow-on offering. The offering consisted of 8,858,121 shares of our common stock at an offering 
price to the public of $18.50 per share, including 1,418,920 shares of common stock upon the exercise in full of the overallotment option by the underwriters, as well as 
pre-funded  warrants  to  purchase  2,020,270  shares  of  common  stock  at  a  public  offering  price  of  $18.4999  per  underlying  share,  in  each  case  before  underwriting 
discounts and commissions. Pursuant to the offering, we received aggregate gross proceeds of approximately $201.3 million, before deducting underwriting discounts 
and commissions and other offering expenses, resulting in net proceeds of approximately $188.7 million, after deducting underwriting discounts and commissions and 
other offering expenses. 

As of December 31, 2023, the following aggregate warrants to purchase shares of the Company’s common stock were issued and outstanding:

The Warrants are classified as a component of Stockholders’ Equity within Additional Paid-in-Capital. The Warrants are equity classified because they are freestanding 
financial instruments that are legally detachable and separately exercisable from the equity instruments, are immediately exercisable, do not embody an obligation for 
the Company to repurchase its shares, are indexed to the Company’s common stock and meet the equity classification criteria. The Warrants will not expire until they 
are fully exercised. As of December 31, 2023, no shares underlying the Warrants had been exercised.

The Company had reserved common stock for future issuance as follows: 

Exercise of outstanding options under the 2015, 2019 and 2023 Plans
Shares available for grant under the 2019 Plan
Shares available for grant under the 2023 Inducement Plan

exclusively for grants of awards to individuals who were not previously employees or directors of the Company as an inducement material to the individual’s entry into 
employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules. The 2023 Inducement Plan was approved by the Company’s board 
of directors without stockholder approval in accordance with such rule. Options granted under the 2023 Inducement Plan have a term of 10 years and generally vest 
over a 4-year period with 1-year cliff vesting.

As of December 31, 2023, the number of shares available for issuance under the 2023 Inducement Plan was 524,300.

2019 Incentive Award Plan

In May 2019, the Company’s board of directors adopted and the Company’s stockholders approved the 2019 Incentive Award Plan (the “2019 Plan”), under which the 
Company may grant cash and equity-based incentive awards to the Company’s employees, consultants and directors. Following the effectiveness of the 2019 Plan, the 
Company will not make any further grants under the 2015 Equity Incentive Plan (the “2015 Plan”). However, the 2015 Plan continues to govern the terms and 
conditions of the outstanding awards granted under it. Shares of common stock subject to awards granted under the 2015 Plan that are forfeited or lapse unexercised and 
which following the effective date of the 2019 Plan are not issued under the 2015 Plan will be available for issuance under the 2019 Plan. 

Options granted under the 2019 Plan may be either incentive stock options (“ISOs”) or nonqualified stock options (“NSOs”). ISOs may be granted only to Company 
employees (including officers and directors who are also employees). NSOs may be granted to Company employees and consultants. 

The 2019 Plan is subject to an annual increase on the first day of each year beginning in 2020 and ending in 2029, equal to the lesser of 4% of the shares outstanding on 
the last day of the immediately preceding fiscal year, and such small number of shares as determined by the Company's board of directors. Options granted under the 
2019 Plan have a term of 10 years (or five years if granted to a 10% stockholder) and generally vest over a 4-year period with 1-year cliff vesting.

As of December 31, 2023, the number of shares available for issuance under the 2019 Plan was 964,622.

2015 Equity Incentive Plan 

In 2015, the Company established its 2015 Plan which provides for the granting of stock options to employees and consultants of the Company. Options granted under 
the 2015 Plan may be either ISOs or NSOs. 

2019 Employee Stock Purchase Plan

In May 2019, the Company’s board of directors adopted and the Company’s stockholders approved the 2019 Employee Stock Purchase Plan (the “ESPP”). The ESPP 
provides eligible employees with the opportunity to acquire an ownership interest in the Company through periodic payroll deductions up to 15% of eligible 
compensation. The offering period is determined by the Company in its discretion but may not exceed 27 months. The per-share purchase price on the applicable 
exercise date for an offering period is equal to the lesser of 85% of the fair market value of the common stock at either the first business day or last business day of the 
offering period, provided that no more than 4,000 shares of common stock may be purchased by any one employee during each offering period. 

The ESPP is intended to constitute an “employee stock purchase plan” under Section 423(b) of the Internal Revenue Code of 1986, as amended. A total of 195,000 
shares of common stock were initially reserved for issuance under the ESPP, subject to an annual increase on January 1 of each year, beginning on January 1, 2020, 
equal to the lesser of 1% of the shares outstanding on the last day of the immediately preceding fiscal year and such number of shares as may be determined by the 
Company's board of directors, provided, however, that no more than 2,500,000 shares may be issued under the ESPP.

As of December 31, 2023, the number of shares available for issuance under the ESPP was 1,317,974. For the years ended December 31, 2023 and December 31, 2022, 
the Company recorded $0.6 million and $0.4 million, respectively, of compensation expense related to employee participation in the ESPP.

The weighted-average grant-date fair value of options granted during the years ended December 31, 2023 and December 31, 2022 was $13.98 and $10.10 per share, 
respectively. The aggregate intrinsic value of options exercised for the years ended December 31, 2023 and December 31, 2022 was $16.9 million and $1.8 million, 
respectively. Intrinsic values are calculated as the difference between the exercise price of the underlying options and the fair value of the common stock on the date of 
exercise. 

As of December 31, 2023 and December 31, 2022, the total unrecognized stock-based compensation expense for stock options was $41.1 million and $28.0 million, 
respectively, which is expected to be recognized over a weighted-average period of 2.59 years and 2.65 years, respectively.

Black-Scholes Assumptions

The fair values of options were calculated using the assumptions set forth below: 

Expected term
Expected volatility
Risk-free interest rate
Dividend yield

2023
6.1 years
81.76% - 86.90%
3.56% - 4.83%
0%

Year Ended December 31,
2022

0%

2021
5.5 - 6.1 years
90.0% - 103.6%
0.6% - 1.4%
0%

Expected term. The expected term represents the weighted-average period the stock options are expected to remain outstanding and is based on the options’ vesting 
terms, contractual terms and industry peers, as the Company does not have sufficient historical information to develop reasonable expectations about future exercise 
patterns and post-vesting employment termination behavior.

Expected Volatility. The expected volatility is based on the Company's historical stock price volatility. The historical stock price volatility is calculated based on a 
period of time commensurate with the expected term assumption for each grant.

Risk-Free Interest Rate. The risk-free rate assumption is based on U.S. Treasury instruments whose term was consistent with the expected term of the Company’s stock 
options. 

Expected Dividend Rate. The Company has not paid and does not anticipate paying any dividends in the near future. Accordingly, the Company has estimated the 
dividend yield to be zero. 

The Company accounts for forfeitures as they occur.

Fair Value of Common Stock 

The fair value of the Company’s common stock is determined based on its market price on the date of grant. 

10. Significant Agreements

GSK Collaboration, Option and License Agreement

In June 2020, we entered into the GSK Collaboration Agreement, with GSK, pursuant to which we and GSK have entered into a collaboration for its synthetic lethality 
programs targeting MAT2A, Pol Theta and Werner Helicase. On July 27, 2020, ("the Effective Date"), we and GSK received Hart-Scott-Rodino Antitrust 
Improvements Act clearance, or HSR Clearance, and the GSK Collaboration Agreement became effective. Pursuant to the GSK Collaboration Agreement, GSK paid 
the Company $100.0 million on July 31, 2020.

Pursuant to the Agreement, GSK paid the Company $100.0 million on July 31, 2020. As of December 31, 2023, GSK has made aggregate payments in the amount of 
$13.0 million for the achievement of certain development and regulatory milestones with respect to Pol Theta and WRN products. 

GSK Collaboration - MAT2A Program

Under the MAT2A program, we led research and development through early clinical development stage, and GSK had an exclusive option to obtain an exclusive 
license to continue development of and commercialize MAT2A products arising out of the MAT2A program, or the Option. We delivered an Option data package 
resulting from our conduct of a dose escalation portion of a MAT2A Phase 1 monotherapy clinical trial pursuant to the GSK Collaboration Agreement, following which 
the Option was exercisable within a specified time period.

In January 2022, GSK waived its rights under the GSK Collaboration Agreement to initiate, or request that we initiate, prior to GSK’s exercise of the Option, a Phase 1 
combination clinical trial for a MAT2A product and GSK’s Type I PRMT inhibitor (GSK3368715) product, or the MAT2A Combination Trial. Accordingly, we have no 
further obligation under the GSK Collaboration Agreement to supply MAT2A product for the MAT2A Combination Trial at its own cost. Our obligation to supply the 
MAT2A compound for the MAT2A Combination Study was deemed a material right under the GSK Collaboration Agreement.

In August 2022, we received notice from GSK waiving its rights to exercise its Option, or the MAT2A Option Waiver, pursuant to the GSK Collaboration Agreement. 
As such, we retain and fully own all right, title and interest in and to IDE397 and the MAT2A program, including all worldwide commercial rights thereto. We will be 
responsible for the costs of further research and clinical development activities that we conduct for the MAT2A program following the MAT2A Option Waiver. 

GSK Collaboration - Pol Theta Program

Pursuant to the GSK Collaboration Agreement, GSK holds a global, exclusive license to develop and commercialize Pol Theta products arising out of the Pol Theta 
program. We and GSK collaborated on preclinical research for the Pol Theta program, and GSK is leading clinical development for the Pol Theta program. GSK is 
responsible for all research and development costs for the Pol Theta program.

We will be eligible to receive total development and regulatory milestones of up to $485 million, with respect to each Pol Theta product, including as applicable, for 
multiple Pol Theta products that target certain alternative protein domains or are based on alternative modalities. Additionally, we will be eligible to receive up to $475 
million of commercial milestones with respect to the Pol Theta product. We are also entitled to receive tiered royalties on global net sales of Pol Theta products by 

F-23

 
 
 
 
 
 
 
 
 
 
GSK, its affiliates and their sublicensees ranging from high single digit to sub-teen double digit percentages, subject to certain customary reductions. 

In June 2022, we announced the nomination of a Pol Theta Helicase Inhibitor DC and in August 2022, announced the achievement of an initial preclinical development 
milestone in connection with ongoing IND-enabling studies to support evaluation of Pol Theta Helicase Inhibitor DC, triggering a $3.0 million milestone payment, 
which we received in October 2022. 

An IND was submitted and was cleared by the FDA in August 2023 to enable clinical evaluation in combination with niraparib, triggering a $7.0 million milestone 
payment.

We have the potential to achieve an additional $10.0 million development milestone upon initiation of Phase 1 clinical dose expansion, as well as potential further 
aggregate late-stage development and regulatory milestones of up to $465 million. We are also entitled to receive tiered royalties on global net sales of Pol Theta 
products by GSK, its affiliates and their sublicensees ranging from high single digit to sub-teen double digit percentages, subject to certain customary reductions.

GSK Collaboration - Werner Helicase Program

Pursuant to the GSK Collaboration Agreement, GSK holds a global, exclusive license to develop and commercialize WRN products arising out of the WRN program. 
We and GSK are collaborating on ongoing preclinical research for the WRN program, and GSK will lead clinical development for the WRN program, with IDEAYA 
responsible for 20% and GSK responsible for 80% of such global research and development costs. The cost-sharing percentages will be adjusted based on the actual 
ratio of U.S. to global profits for WRN products, as measured three and six years after global commercial launch thereof. 

We will be eligible to receive total development milestones of up to $485.0 million, with respect to each WRN product, including as applicable, for multiple WRN 
products that are based on alternative modalities. Additionally, we will be eligible to receive up to $475 million of commercial milestones with respect to each WRN 
product. We will be entitled to receive 50% of U.S. net profits and tiered royalties on global non-U.S. net sales of WRN products by GSK, its affiliates and their 
sublicensees ranging from high single digit to sub-teen double digit percentages, subject to certain customary reductions. We will have a right to opt-out of the 50% 
U.S. net profit share and corresponding research and development cost share for the WRN program, and would be eligible to receive tiered royalties on U.S. net sales of 
WRN products by GSK, its affiliates and their sublicensees at the same royalty rates as for global non-U.S. net sales thereafter, with economic adjustments based on the 
stage of the WRN program at the time of opt-out.

In October 2023, we earned a $3.0 million milestone from GSK in connection with IND-enabling studies for the Werner Helicase Inhibitor DC.

GSK Collaboration - General

Under the terms of the GSK Collaboration Agreement, subject to certain exceptions, we and GSK will not, directly or through third parties, develop or commercialize 
other products whose primary and intended mechanism of action is the modulation of WRN or Pol Theta for an agreed upon period of time. We and GSK have formed a 
joint steering committee, joint development committees, and joint commercialization committees responsible for coordinating all activities under the GSK 
Collaboration Agreement. Ownership of intellectual property developed under the GSK Collaboration Agreement is allocated between or shared by the parties 
depending on development and subject matter.

GSK’s royalty obligations continue with respect to each country and each product until the later of (i) the date on which such product is no longer covered by certain 
intellectual property rights in such country and (ii) the 10th anniversary of the first commercial sale of such product in such country.

Each party has the right to sublicense its rights under the GSK Collaboration Agreement subject to certain conditions.

The GSK Collaboration Agreement will continue in effect on a product-by-product and country-by-country basis until the expiration of the obligation to make 
payments under the GSK Collaboration Agreement with respect to such product in each country, unless earlier terminated by either party pursuant to its terms. Either 
party may terminate the GSK Collaboration Agreement for the other party’s insolvency or certain uncured breaches. We may terminate the GSK Collaboration 
Agreement if GSK or any of its sublicensees or affiliates challenge certain patents of ours. GSK may terminate the GSK Collaboration Agreement in its entirety or on a 
target-by-target basis upon 90-day notice to us.

Pfizer Clinical Trial Collaboration and Supply Agreements

In March 2020, we entered into the Pfizer Agreement. Pursuant to the Pfizer Agreement, as amended in September 2020, April 2021, September 2021 and May 2023, 
Pfizer supplies us with their MEK inhibitor, binimetinib, and their cMET inhibitor, crizotinib, to evaluate combinations of darovasertib independently with each of the 
Pfizer compounds, in patients with tumors harboring activating GNAQ or GNA11 mutations. Under the Pfizer Agreement, we are the sponsor of the combination 
studies and will provide darovasertib and pay for the costs of the combination studies. Pfizer will provide binimetinib and crizotinib for use in the clinical trial at no cost 
to us. The Pfizer Agreement provides that we and Pfizer will jointly own clinical data generated from the clinical trial and will also jointly own inventions, if any, 
relating to the combined use of darovasertib and binimetinib, or independently, to the combined use of darovasertib and crizotinib. We and Pfizer have formed a joint 
development committee responsible for coordinating all regulatory and other activities under the agreement. 

In March 2022, we and Pfizer entered into the Second Pfizer Agreement pursuant to which we may, subject to FDA feedback and guidance, evaluate darovasertib and 
crizotinib as a combination therapy in MUM in a planned Phase 2/3 potential registration-enabling clinical trial. Pursuant to the Second Pfizer Agreement, we are the 
sponsor of the planned combination trial and we will provide darovasertib and pay for the costs of the combination trial; Pfizer will provide crizotinib for the planned 
combination trial at no cost to us for up to an agreed-upon number of MUM patients. We and Pfizer will jointly own clinical data from the planned combination trial 
and all inventions relating to the combined use of darovasertib and crizotinib. We and Pfizer have formed a joint development committee responsible for coordinating 
all regulatory and other activities under the Second Pfizer Agreement. 

Separately, in March 2022, we and Pfizer also entered into the Third Pfizer Agreement pursuant to which we may, subject to preclinical validation and FDA feedback 
and guidance, evaluate darovasertib and crizotinib, as a combination therapy in cMET-driven tumors such as NSCLC and/or HCC in a Phase 1 clinical trial. Pursuant to 
the Third Pfizer Agreement, we are the sponsor of the planned combination trial, and we will provide darovasertib and pay for the costs of the combination trial; Pfizer 
will provide crizotinib for the planned combination trial at no cost to us. We and Pfizer will jointly own clinical data from the planned combination trial and all 
inventions relating to the combined use of darovasertib and crizotinib. We and Pfizer had formed a joint development committee responsible for coordinating all 
regulatory and other activities under the Third Pfizer Agreement. 

In May 2023, we continued our relationship with Pfizer by entering into Amendment No. 4 to the Pfizer Agreement relating to the supply of crizotinib in support of this 
Phase 2 clinical trial, pursuant to which Pfizer will continue to provide us with an additional defined quantity of crizotinib at no cost.

We also expanded our relationship with Pfizer in May 2023 under an Amendment No. 1 to the Second Pfizer Agreement to support the Phase 2/3 registrational trial to 
evaluate darovasertib and crizotinib as a combination therapy in MUM. Under the as-amended Second Pfizer Agreement, Pfizer will provide us with a first defined 
quantity of crizotinib at no cost, as well as an additional second defined quantity of crizotinib at a lump-sum cost. Under Amendment No. 1 to the Second Pfizer 
Agreement, we also terminated the Third Pfizer Agreement. 

Novartis License Agreement

In September 2018, we entered into a license agreement with Novartis International Pharmaceuticals Ltd. ("Novartis") to develop and commercialize Novartis’ LXS196 
(also known as IDE196), a Phase 1 protein kinase C ("PKC") inhibitor, for the treatment of cancers having GNAQ and GNA11 mutations. We have renamed Novartis’ 
LXS196 oncology as IDE196, and which has a non-proprietary name of darovasertib. Under the license agreement, the Company is liable to make contingent 
development and sales-based milestone payments of up to $29.0 million and mid to high single-digit royalty payments based on net sales of the licensed products. 
Because the achievement of these milestones had not occurred or was not considered probable as of December 31, 2023, such contingencies have not been recorded in 
the Company's financial statements.

Amgen Clinical Trial Collaboration and Supply Agreement

In July 2022, we entered into the Amgen CTCSA to clinically evaluate IDE397 in combination with AMG 193 in patients having MTAP-null solid tumors, in a Phase 
1/2 clinical trial. Under the mutually non-exclusive Amgen CTCSA, we will provide IDE397 drug supply to Amgen, who will be the sponsor of the Phase 1 clinical 
combination trial evaluating IDE397 and AMG 193. Each party will pay for fifty percent (50%) of the external third-party costs of the combination study. Each party 
will be responsible for its own internal costs and expenses in support of the combination study. We and Amgen will jointly oversee clinical development of the 
combination therapy through a Joint Oversight Committee responsible for coordinating all regulatory and other activities under the Amgen CTCSA. The parties will 
jointly own collaboration data and combination-related intellectual property, if any, arising from the combination clinical trial. We and Amgen each retain commercial 
rights to our respective compounds, including with respect to use as a monotherapy agent or combination agent.

Gilead Clinical Trial Collaboration and Supply Agreement 

In November 2023, the Company entered into the Gilead CSCSA with Gilead to clinically evaluate IDE397 in combination with Trodelvy, the Gilead Trop-2 directed 
ADC, in patients having MTAP deletion bladder cancer, in an IDEAYA-sponsored clinical trial pursuant to the Gilead CSCSA. Under the mutually non-exclusive 
Gilead CSCSA, we will receive Trodelvy drug supply from Gilead and will sponsor the Phase 1 clinical combination trial evaluating ID397 and Trodelvy. Gilead will 
bear internal or external costs incurred in connection with its supply of Trodelvy. We will bear all internal and external costs and expenses associated with the conduct 
of the combination study. We and Gilead will jointly oversee clinical development of the combination therapy through a Joint Steering Committee responsible for 
coordinating all regulatory and other activities under the Gilead CSCSA. We and Gilead each retain commercial rights to our respective compounds, including with 
respect to use as a monotherapy agent or combination agent.

Cancer Research UK and University of Manchester Exclusive Option and License Agreement 

In January 2022, the Company exercised its option for an exclusive worldwide license covering a broad class of PARG inhibitors from Cancer Research Technology 
Ltd. (CRT) and the University of Manchester, and in connection therewith, paid a one-time option exercise fee of £250,000. The Company will be obligated to make 
payments to CRT aggregating up to a total of £19.5 million upon the achievement of specific development and regulatory approval events for development of a PARG 
inhibitor in oncologic diseases. The Company will also pay low single-digit tiered royalties, and potentially also sales-based milestones, to CRT based on net sales of 
licensed products. In addition, in the event the Company sublicenses the intellectual property, it will also be obligated to pay CRT a specified percentage of any 
sublicense revenue.

In April 2023, we incurred an obligation to pay milestone payments in an aggregate amount of £750,000 to CRT based upon the achievement of certain milestones 
relating to first and second tumor histologies in connection with the Phase 1 portion of the Phase 1/2 clinical trial in oncologic diseases.

The Company will be obligated to make additional payments to CRT aggregating up to £18.75 million upon the achievement of specific development and regulatory 
approval events for development of a PARG inhibitor in oncologic diseases, including an aggregate of up to £1.5 million and up to £2.25 for the achievement of certain 
Phase 2 and Phase 3 development milestones, respectively, in each case as relating to first and second tumor histologies.

11. Revenue Recognition

The Company recognizes revenue in accordance with ASC 606 for the GSK Collaboration Agreement (see No. 10, Significant Agreements).

As of December 31, 2023 and December 31, 2022, the Company had accounts receivable of zero and $0.2 million, respectively, and contract liabilities of zero and 
$13.8 million, respectively, related to the GSK Collaboration Agreement.

As of December 31, 2023, we have fully recognized the contract liabilities related to the upfront payment and reimbursements for the research and development 
performance obligations under the GSK Collaboration Agreement. There are no remaining contract liabilities as of December 31, 2023 as we concluded all the research 
and development performance obligations under the GSK Collaboration Agreement. The future revenue recognition will be contingent on additional milestones earned, 
profit sharing and royalties on any net product sales under our collaborations. We expect that any revenue

we recognize or generate under the GSK Collaboration Agreement will fluctuate from period to period due to period to period variability in milestone payments and 
other payments. 

Performance obligations

The Company has identified the following six performance obligations associated with the GSK Collaboration Agreement:

(i)

(ii)

Preclinical and Phase 1 Monotherapy clinical research and development services under the MAT2A program (“MAT2A R&D Services”)

Preclinical research services and the related license to IDEAYA-owned technology under the Pol Theta program (“Pol Theta R&D Services”)

(iii)

Preclinical research services and the related license to IDEAYA-owned technology under the WRN program (“WRN R&D Services”)

(iv) Material right associated with the option to license IDEAYA-owned technology under the MAT2A program (“Option”)

(v)

Material right associated with the option to license to IDEAYA-owned technology under the MAT2A program to the extent necessary for preclinical 
activities in preparation for the MAT2A Combination Trial (“Preclinical MAT2A License”)

(vi) Material right associated with the supply of MAT2A product for the MAT2A Combination Trial (“MAT2A Supply”)

The Company recognizes revenue related to amounts allocated to the MAT2A R&D services as the underlying services are performed over the period through the 
delivery of the Option data package, which is generated from its conduct of the dose escalation portion of the MAT2A Phase 1 monotherapy clinical trial. The Company 
uses its internal research and development capability and also engages third-party clinical research organizations, or CROs, for which the Company acts as a principal. 
The Company has delivered the Option data package to GSK. Accordingly, the performance obligation related to the MAT2A R&D services has been fulfilled. 

With respect to the Pol Theta and WRN programs, the Company identified two promises: (1) granting of the license to develop and commercialize Pol Theta and WRN 
products, respectively, and (2) the preclinical research services. The Company has determined that these two promises are not distinct within the context of the contract. 

After the Company and GSK identify a development candidate, a series of IND-enabling studies will be conducted before an Investigational New Drug application is 
submitted to the FDA. Due to the early stage of development, the Company’s preclinical research services are expected to transform the underlying technology and 
significantly modify or customize the license. Therefore, the two promises are not distinct from each other and are accounted for as a single performance obligation for 
each of the Pol Theta and WRN programs, respectively. An IND for GSK101 was submitted and has been cleared by the FDA and GSK has dosed a first patient in the 
Phase 1 clinical trial. GSK plans to evaluate GSK101 in combination with niraparib, the GSK small molecule inhibitor of PARP for the treatment of patients having 
tumors with BRCA or other HRD. 

For the Pol Theta product, we achieved and earned a $7.0 million payment for a milestone in August 2023 based on acceptance of the IND by the FDA, payment. An 
earlier preclinical development $3.0 million milestone payment from GSK was achieved in August 2022 in connection with ongoing IND-enabling studies to support 
evaluation of GSK101. We have the potential to receive an additional $10.0 million milestone payment upon initiation of Phase 1 clinical dose expansion. 

For the WRN product, we achieved and earned a $3.0 million payment for a milestone in October 2023 in connection with IND-enabling studies for the Werner 
Helicase Inhibitor DC. We are, in collaboration with GSK, targeting an IND submission in 2024 to enable first-in-human clinical evaluation of our Werner Helicase 
Inhibitor DC in high MSI tumors.

The Company recognized revenue related to amounts allocated to the Pol Theta R&D Services and WRN R&D Services as the underlying services are performed over 
the period through the completion of the Pol Theta and WRN preclinical research programs, respectively. Within 90 days from the end of each calendar quarter, GSK 
reimbursed the Pol Theta program costs incurred by the Company. Within 75 days from the end of each calendar quarter, the Company and GSK determined the 
amounts of WRN program costs incurred by both parties and the net amount owed by GSK to the Company or by the Company to GSK, which was paid within 75 days 
from such determination by a reimbursing party. The Company used its internal research capability and may also engage third-party clinical research organizations, or 
CROs, in transferring the Pol Theta R&D services and WRN R&D services, for which the Company acts as a principal. The Company completed Pol 

F-27

 
 
 
 
 
 
 
Theta R&D services during December 2022. Accordingly, the performance obligation related to the Pol Theta R&D services has been fulfilled.

Subject to exercise of the Option, at Option closing following HSR clearance, GSK would have obtained an exclusive license to develop and commercialize MAT2A 
products. The Company has concluded that this Option results in a material right as the option exercise fee contains a discount that GSK would not have otherwise 
received. The Company has determined the nature of the license to develop and commercialize MAT2A products to be functional. 

The Company delivered an Option data package to GSK pursuant to the GSK Collaboration Agreement comprising preclinical and clinical data resulting from the 
Company's conduct of a dose-escalation portion of the MAT2A Phase 1 monotherapy clinical trial, following which, the Option was exercisable by GSK within a 
specified period of time. In August 2022, the Company received notice from GSK waiving its rights to exercise its Option to obtain an exclusive license to further 
develop and commercialize IDE397, as well as other IDEAYA compounds, if any, directly targeting MAT2A, or the GSK MAT2A Option Waiver, pursuant to the GSK 
Collaboration Agreement. As such, the Company retains and fully owns all right, title and interest in and to IDE397 and the MAT2A program, including all worldwide 
commercial rights thereto. The Company will be responsible for the costs of further research and clinical development activities that the Company conducts for the 
MAT2A program following the GSK MAT2A Option Waiver. Accordingly, the Company recognized revenue of $17.4 million related to GSK's waiver of its rights to 
exercise its Option during the year ended December 31, 2022.

If GSK had elected to conduct the MAT2A Combination Trial, the Company would have an obligation to supply MAT2A product to be used for the MAT2A 
Combination Trial at its own cost. The Company has concluded that this supply option results in a material right as it involves a discount that GSK would not have 
otherwise received. The Company would have recognized revenue, as it transferred the control of the MAT2A product to GSK. In January 2022, GSK waived its rights 
under the GSK Collaboration Agreement to initiate, or request that the Company initiate, prior to GSK’s exercise of the Option, a Phase 1 combination clinical trial for 
a MAT2A product and GSK’s Type I PRMT inhibitor (GSK3368715) product, or the MAT2A Combination Trial. Accordingly, the Company has no further obligation 
under the GSK Collaboration Agreement to supply MAT2A product for the MAT2A Combination Trial at its own cost. The Company recognized revenue of $2.4 
million during the year ended 2022 related to the material right to supply MAT2A compound as the material right no longer exists and the Company has no further 
obligation related to the MAT2A Combination Trial.

As of December 31, 2023, there are no remaining performance obligations related to the WRN, Pol Theta and MAT2A program. 

Significant judgments

In applying ASC 606 to the GSK Collaboration Agreement, the Company made the following judgments that significantly affect the timing and amount of revenue 
recognition:

(i) Determination of the transaction price, including whether any variable consideration is included at inception of the contract

The transaction price is the amount of consideration that the Company expects to be entitled to in exchange for transferring promised goods or services to the customer. 
The transaction price must be determined at inception of a contract and may include amounts of variable consideration. However, there is a constraint on inclusion of 
variable consideration in the transaction price, if there is uncertainty at inception of the contract as to whether such consideration will be recognized in the future.

The decision as to whether or not it is probable that a significant reversal of revenue will occur in the future, depends on the likelihood and magnitude of the reversal 
and is highly susceptible to factors outside the Company’s influence (for example, the Company cannot determine the outcome of clinical trials; the Company cannot 
determine if or when the counterparty will initiate or complete clinical trials; and the Company cannot determine if or when an regulatory agency provides any 
approval). In addition, the uncertainty is not expected to be resolved for a long period and finally, the Company has limited experience in the field. Therefore, at 
inception of the GSK Collaboration Agreement, development and regulatory milestones were fully constrained and were not included in the transaction price based on 
the factors noted above.

The Company constrains estimates of other variable consideration, such as reimbursable program costs, to amounts that are not expected to result in a significant 
revenue reversal in the future. The Company re-evaluates the transaction price, including the estimated variable consideration included in the transaction price and all 
constrained amounts, in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

(ii) Determination of the timing of satisfaction of performance obligations

F-28

 
 
 
 
The Company recognizes revenue from the MAT2A R&D Services, Pol Theta R&D Services and WRN R&D Services over time, as GSK simultaneously receives and 
consumes the benefits provided by the Company’s performance as the Company performs. The Company measures its progress toward complete satisfaction of the 
MAT2A R&D Services, Pol Theta R&D Services and WRN R&D Services based on the costs incurred as a percentage of the estimated total costs to be incurred to 
complete the performance obligations. As the Company performs, it shares the results of research and development studies with GSK through the joint development 
committee. Accordingly, the cost incurred method faithfully depicts the Company’s performance of the MAT2A R&D Services, Pol Theta R&D Services and WRN 
R&D Services.

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 
1934 

IDEAYA Biosciences (“we,” “us,” or “our”) has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended: our 

common stock, $0.0001 par value per share (“common stock”). 

Description of Capital Stock

The following summary describes our common stock and the material provisions of our amended and restated certificate of incorporation (the “certificate of 

incorporation”), our amended and restated bylaws (the “bylaws”), the amended and restated investors’ rights agreement (the “investors’ rights agreement”), each as 
amended from time to time, to which we and certain of our stockholders are parties, and of the Delaware General Corporation Law (the “DGCL”). Because the 
following is only a summary, it does not contain all of the information that may be important to you. For a complete description, you should refer to the full text of our 
certificate of incorporation, bylaws and investors’ rights agreement.  We encourage you to read those documents and the DGCL carefully. 

General 

The certificate of incorporation authorizes 300,000,000 shares of common stock, $0.0001 par value per share. 

Common Stock 

Voting Rights 

Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. 

Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the 
directors. In addition, the affirmative vote of holders of 66-2/3% of the voting power of all of the then outstanding voting stock is required to take certain actions, 
including amending certain provisions of our amended and restated certificate of incorporation, such as the provisions relating to amending our amended and restated 
bylaws, the classified board and director liability. 

Dividends 

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive dividends, if any, as may 

be declared from time to time by our board of directors out of legally available funds. 

Liquidation 

In the event of our liquidation, dissolution or winding up, holders of our common stock are entitled to share ratably in the net assets legally available for 

distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then 
outstanding shares of preferred stock. 

Rights and Preferences 

Holders of our common stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to 

our common stock. The rights, preferences and privileges of the 

 
 
 
 
 
 
 
 
 
 
 
       
 
 
 
 
 
 
 
 
 
 
holders of our common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of our preferred stock that we may 
designate in the future. 

Fully Paid and Nonassessable 

All outstanding shares of common stock are fully paid and non-assessable. 

Undesignated Preferred Stock 

Under our certificate of incorporation, our board of directors has the authority, without further action by our stockholders, to issue up to 10,000,000 shares of 

preferred stock, $0.0001 par value per share, in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and 
privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares 
constituting, or the designation of, such series, any or all of which may be greater than the rights of common stock. The issuance of our preferred stock could adversely 
affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon our liquidation. In addition, 
the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in control of our company or other corporate action. No shares of 
preferred stock are outstanding, and we have no present plan to issue any shares of preferred stock. 

Registration Rights 

Certain holders of unregistered common stock purchased in private placements, or their permitted transferees, are entitled to rights with respect to the registration 

of such shares under the Securities Act of 1933, as amended (the “Securities Act”). These rights are provided under the terms of (i) an investors’ rights agreement 
between us and the holders of certain of these shares, or the investors’ rights agreement, which include demand registration rights and piggyback registration rights, and 
(ii) a stock purchase agreement between us and the holder of certain of these shares, or the stock purchase agreement, which include Form S-3 registration rights. All 
fees, costs and expenses of underwritten registrations will be borne by us and all selling expenses, including underwriting discounts and selling commissions, will be 
borne by the holders of the shares being registered. 

The demand, piggyback and Form S-3 registration rights will expire, with respect to any particular stockholder party to the investors’ rights agreement, upon the 
earliest of (i) three years after the consummation of our initial public offering, (ii) when that stockholder can sell all of its shares under Rule 144 of the Securities Act 
during any 90-day period or (iii) upon the consummation of an acquisition. The Form S-3 registration rights will expire, with respect to the stockholder party to the 
stock purchase agreement, when such stockholder can sell all of its shares under Rule 144 of the Securities Act during any 90-day period.

Anti-Takeover Effects of Provisions of Our Amended and Restated Certificate of Incorporation, Our Amended and Restated Bylaws and Delaware Law 

Some provisions of Delaware law and our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that could 
make the following transactions more difficult: acquisition of us by means of a tender offer; acquisition of us by means of a proxy contest or otherwise; or removal of 
our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may 
otherwise consider to be in their best interest or in our best interests, including transactions that might result in a premium over the market price for our shares. 

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to 

encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential 
ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals 
because negotiation of these proposals could result in an improvement of their terms. 

Delaware Anti-Takeover Statute 

 
 
 
 
 
 
 
 
 
 
  We are subject to Section 203 of the DGCL, which prohibits persons deemed “interested stockholders” from engaging in a “business combination” with a publicly-
held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in 
which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested 
stockholder” is a person who, together with affiliates and associates, beneficially owns, or within three years prior to the determination of interested stockholder status 
did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a 
financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by 
the board of directors, such as discouraging takeover attempts that might result in a premium over the market price of our common stock. 

Undesignated Preferred Stock 

The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences 
that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deterring hostile takeovers or delaying changes 
in control or management of our company. 

Special Stockholder Meetings 

Our amended and restated bylaws provide that a special meeting of stockholders may be called by our board of directors, or by our President or Chief Executive 

Officer. 

Requirements for Advance Notification of Stockholder Nominations and Proposals 

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as 

directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors. 

Elimination of Stockholder Action by Written Consent 

Our amended and restated certificate of incorporation and our amended and restated bylaws eliminate the right of stockholders to act by written consent without a 

meeting. 

Classified Board; Election and Removal of Directors; Filling Vacancies 

Our board of directors is divided into three classes. The directors in each class will serve for a three-year term, one class being elected each year by our 

stockholders, with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing 
for the remainder of their respective three-year terms. Because our stockholders do not have cumulative voting rights, our stockholders holding a majority of the shares 
of common stock outstanding will be able to elect all of our directors. Our amended and restated certificate of incorporation provides for the removal of any of our 
directors only for cause and requires a stockholder vote by the holders of at least a 66-2/3% of the voting power of the then outstanding voting stock. Furthermore, any 
vacancy on our board of directors, however occurring, including a vacancy resulting from an increase in the size of the board, may only be filled by a resolution of the 
board of directors unless the board of directors determines that such vacancies shall be filled by the stockholders. This system of electing and removing directors and 
filling vacancies may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more 
difficult for stockholders to replace a majority of the directors. 

Choice of Forum 

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of 

the State of Delaware will be the exclusive forum for: any state law derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary 
duty; any action asserting a claim against us arising pursuant to the DGCL; or any action asserting a claim against us that 

 
 
 
 
 
 
 
 
 
is governed by the internal affairs doctrine. Similarly, our amended and restated certificate of incorporation provides that the U.S. federal district courts are the 
exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. The enforceability of similar choice of forum provisions 
has been challenged in legal proceedings, and it is possible that, in connection with such actions or any future actions, a court could find the choice of forum provisions 
contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable. Although our amended and restated certificate of incorporation 
contains the choice of forum provision described above, it is possible that a court could find that such provisions are inapplicable for a particular claim or action or that 
such provisions are unenforceable. 

Amendment of the Certificate of Incorporation and Bylaws 

The amendment of any of the above provisions, except for the provision making it possible for our board of directors to issue undesignated preferred stock, would 

require approval by a stockholder vote by the holders of at least a 66-2/3% of the voting power of the then outstanding voting stock. 

The provisions of the DGCL, our amended and restated certificate of incorporation and our amended and restated bylaws could have the effect of discouraging 

others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result 
from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these 
provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests. 

Limitations of Liability and Indemnification Matters 

Our amended and restated certificate of incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent 
permitted by Delaware law. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties 
as directors, except liability for: 

•

•

•

•

  any breach of the director’s duty of loyalty to us or our stockholders; 

  any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law; 

  unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or 

  any transaction from which the director derived an improper personal benefit. 

Each of our amended and restated certificate of incorporation and amended and restated bylaws provide that we are required to indemnify our directors and 
officers, in each case to the fullest extent permitted by Delaware law. Our amended and restated bylaws also obligate us to advance expenses incurred by a director or 
officer in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee or other agent for 
any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under Delaware law. We 
have entered and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by our board of directors. 
With specified exceptions, these agreements provide for indemnification for related expenses including, among other things, attorneys’ fees, judgments, fines and 
settlement amounts incurred by any of these individuals in any action or proceeding. We believe that these bylaw provisions and indemnification agreements are 
necessary to attract and retain qualified persons as directors and officers. We also maintain directors’ and officers’ liability insurance. 

The limitation of liability and indemnification provisions in our amended and restated certificate of incorporation and amended and restated bylaws may 

discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duty. They may also reduce the likelihood of derivative 
litigation against our directors and officers, even though an action, if successful, might benefit us and our stockholders. Further, a stockholder’s investment may be 
adversely affected to the extent that we pay the costs of settlement and damages.

studies other than the Gilead Arm relating to its Compound (or other compounds or products), either individually or in combination with 
any other compound or product, in any therapeutic area, or (b) to create any exclusive relationship between the Parties or otherwise prohibit

writing, such approval not to be unreasonably withheld, conditioned or delayed. 

(c)

Company  shall  have  the  right  to  amend  the  Protocol  or  the  Statistical  Analysis  Plan  (in  each  case,  after  its

4.5Data Privacy.

4.5.1 Roles of the Parties.  To the extent such concept is recognized under Data Protection Laws, each of Gilead and 
Company are independent data controllers with respect to any Personal Data provided or disclosed by or on behalf of a Party to the other 
Party under this Agreement (“Covered Personal Data”), except as otherwise agreed in writing by the Parties.  Each Party is independently 
responsible  for  Processing  Personal  Data  (including  any  Covered  Personal  Data)  in  its  possession  or  control  in  accordance  with  Data 
Protection Laws, and each Party shall comply with all Data Protection Laws and not intentionally take any actions or fail to take any actions 
that would cause the other Party to be in violation of Data Protection Laws.  Company shall provide all notices, obtain all consents and 
authorizations, and otherwise act in a manner so as to ensure that there is no prohibition or restriction that (a) prohibits or restricts Company 
from  disclosing  or  transferring  data  (including  Clinical  Data,  Control  Arm  Data  and  Sample  Analysis  Results)  to  Gilead  as  required  or 
contemplated  under  this  Agreement  or  (b)  prohibits  or  restricts  Gilead  from  Processing  such  data  as  required  or  permitted  under  this 
Agreement.    Notwithstanding  the  foregoing,  if  Company  becomes  aware  of  any  legal  or  other  circumstances  that  it  believes,  acting 
reasonably, may give rise to such a prohibition or restriction, it shall promptly notify Gilead of the same and take all reasonable steps, at 
Gilead’s  cost  and  expense,  including  following  Gilead’s  reasonable  instructions,  to  ensure  that  it  reasonably  minimizes  any  impact  on 
Gilead or its performance under this Agreement. 

4.5.2 Data Processing Commitments.

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.

 
(a)

The Party that provides or discloses Covered Personal Data (“Data Disclosing Party”) to the other Party (“Data 
Receiving Party”) represents and warrants that (i) it has all necessary consents, approvals, authorizations and rights to provide or disclose 
such Covered Personal Data to the Data Receiving Party, and for the Data Receiving Party to Process the Covered Personal Data, for the 
purposes contemplated under the Agreement; (ii) it shall not provide or disclose any Personal Data to the Data Receiving Party except in 
accordance with Data Protection Laws; and (iii) its disclosure of Personal Data to the Data Receiving Party, and the Data Receiving Party’s 
Processing of Personal Data as required or permitted hereby, is in accordance with any notices supplied to, and consents or authorizations 
obtained from, data subjects.

(b)

Each  Party  agrees  to  notify  the  other  Party  in  writing  (i)  immediately,  if  such  Party  becomes  aware  of  any 
investigation by or communication from any government authority relating to Personal Data Processed in connection with this Agreement, 
in  which  case  such  Party  shall  also  inform  the  other  Party  of  all  material  information  relating  to  the  circumstances  giving  rise  to  such 
claims; and (ii) promptly, if such Party receives any inquiry, notice or complaint from any individual relating to Personal Data about that 
individual. 

4.5.3 International Transfers.  The Parties agree to enter any supplemental terms that are or become required under 
Data  Protection  Laws,  including  one  or  more  data  transfer  agreements  that  may  be  required  with  respect  to  the  international  transfer  of 
Covered  Personal  Data.    Without  limitation,  with  respect  to  any  transfer  by  a  Data  Disclosing  Party  of  Covered  Personal  Data  from  the 
European Union to any jurisdiction outside the European Economic Area, the Parties shall comply with the Model Clauses to the extent 
required to ensure that such transfer complies with Data Protection Laws.  Upon the request of either Party to enable it to comply with Data 
Protection Laws, the Parties shall separately execute the Model Clauses.  For the avoidance of doubt, the Parties shall comply with both the 
terms of the Agreement and the terms of the Model Clauses when Processing Covered Personal Data, however, in the event of a conflict 
between the Agreement and the Model Clauses, the terms of the Model Clauses shall control and govern.

4.5.4 Cooperation of the Parties.  Upon request, each Party shall provide to the other Party, at such other Party’s cost 
and expense, commercially reasonable assistance as is reasonably requested to enable the requesting Party to comply with its obligations 
under Data Protection Laws.  Without limitation, Company shall provide, or shall ensure that Gilead Arm site personnel provide, Gilead 
with  reasonable  assistance  in  addressing  data  subject  rights  (e.g.,  rights  to  access,  correct,  delete,  and  object  to  Processing  of  Covered 
Personal Data), conducting privacy impact assessments at Gilead’s cost and expense, and responding to data subject inquiries, in each case, 
in accordance with industry practices and Data Protection Laws.  With respect to any Personal Data that a Party Processes on behalf of the 
other Party, the Parties shall enter a supplemental data processing agreement(s), and, with respect to any Processing of Personal Data for 
which the Parties jointly determine the purposes and means of Processing, the Parties shall enter

designed to (a) maintain the security and confidentiality of the Clinical Data, Sample Analysis Results and any other Covered Personal Data 
provided  or  disclosed  hereunder  and  the  systems  on  which  such  data  is  processed;  (b)  protect  against  reasonably  anticipated  threats  or 
hazards to the security or integrity of such data and systems; and (c) protect against unauthorized access to or use of such data and systems.  
Without limitation, Company shall ensure that the Clinical Data, Control Arm Data, Sample Analysis Results and any other data provided 
by Company to Gilead are coded or otherwise pseudonymized in accordance with industry standards to protect data subject confidentiality.

pharmacovigilance  agreement  to  ensure  the  exchange  of  relevant  safety  data  within  appropriate  timeframes  and  in  appropriate  format  to 
enable  the  Parties  to  fulfill  their  regulatory  reporting  obligations  and  to  facilitate  appropriate  safety  reviews,  all  in  accordance  with 
Applicable Laws (“Pharmacovigilance Agreement”).  From and after the effective date thereof, each Party shall perform its obligations 
under  the  Pharmacovigilance  Agreement.    In  the  event  of  a  conflict  between  the  terms  of  this  Agreement  and  the  terms  of  the 
Pharmacovigilance  Agreement,  the  terms  of  the  Pharmacovigilance  Agreement  shall  control  to  the  extent  related  to  pharmacovigilance 
matters, and the terms of this Agreement shall control in all other respects.  Without limiting the foregoing, any disagreement regarding 
pharmacovigilance matters under the Pharmacovigilance Agreement shall be resolved in accordance with the applicable dispute resolution 
mechanism set forth in the Pharmacovigilance Agreement.

the  Protocol  and  (b)  not  caused  by  (i)  negligence  or  willful  misconduct  on  the  part  of  Company  (or  any  of  its  Affiliates,  or  its  or  their 
employees,  directors  or  agents),  (ii)  Company’s  breach  of  this  Agreement,  (iii)  any  violation  of  Applicable  Law  by  Company,  (iv)  any

notice  to  the  other  Party  (the  “Indemnifying  Party”)  promptly  after  learning  of  the  applicable  Third  Party  Claim.    The  Indemnifying 
Party’s obligation to defend, indemnify, and hold harmless under this Section 13.2 shall be reduced to the extent the Indemnified Party’s

[***] days after receipt of the notice thereof.  The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the

consent of the Indemnified Party, not to be unreasonably withheld, conditioned or delayed, unless the settlement involves only the payment 
of money.  The Indemnified Party shall not settle any such Third Party Claim without the prior written consent of the Indemnifying Party, 
which consent shall not be unreasonably withheld, conditioned or delayed.  Notwithstanding the foregoing, if the Indemnifying Party does 
not assume and conduct the defense of the Third Party Claim as provided above, (a) the Indemnified Party

manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent 
from, the Indemnifying Party in connection therewith), and (b) the Indemnified Party reserves any right it may have under this Section 13.2 
to obtain indemnification from the Indemnifying Party.

13.3LIMITATION OF LIABILITY.  IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR 
ANY  SPECIAL,  INDIRECT,  INCIDENTAL,  PUNITIVE,  EXEMPLARY  OR  CONSEQUENTIAL  DAMAGES,  OR  ANY  DAMAGES 
FOR  LOST  PROFITS  OR  LOST  OPPORTUNITIES,  ARISING  OUT  OF  OR  IN  CONNECTION  WITH  THIS  AGREEMENT, 
WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE; PROVIDED, HOWEVER, 
THAT THE FOREGOING SHALL NOT LIMIT (A) A PARTY’S INDEMNIFICATION OBLIGATIONS UNDER SECTION 13.2, (B) A 
PARTY’S LIABILITY FOR BREACH OF ANY OF ITS OBLIGATIONS UNDER ARTICLE 8 OR ARTICLE 9, OR (C) COMPANY’S 
BREACH OF ITS OBLIGATIONS UNDER SECTION 4.1.2(B) OR 7.2.3(A)(I).

Agreement.    Subject  to  Section  14.3.2,  any  dispute,  claim  or  controversy  arising  out  of  or  related  to  this  Agreement  shall  be  brought

Pharmacovigilance  Agreement  (which,  for  clarity,  shall  be  governed  by  the  applicable  dispute  resolution  mechanism  set  forth  in  the 
Pharmacovigilance  Agreement)  (“Dispute”),  shall  be  resolved,  if  possible,  through  good  faith  negotiations  between  the  Parties.    If  the 
Parties are unable to resolve any Dispute within [***] days after the first discussions relating thereto, then such Dispute shall be referred to 
the Senior Executives, who shall in good faith attempt to resolve such Dispute.  Any resolution agreed in writing by the Senior Executives 
shall  be  final  and  binding  on  the  Parties.    Any  negotiations  pursuant  to  this  Section  14.3.2  are  confidential  and  shall  be  treated  as 
compromise and settlement negotiations for purposes of applicable rules of evidence.  If the Senior Executives cannot resolve such Dispute 
within  [***]  days  after  referral  to  them,  then  either  Party  shall  have  the  right  to  pursue  any  and  all  remedies  available  at  law  or  equity, 
consistent with Section 14.3.1.  Notwithstanding any other provision of this Agreement, the Parties shall be entitled to seek equitable relief,

for the Southern District of New York without first having complied with the procedures set forth in this Section 14.3.2.  Such remedies

breaches this Agreement and such material breach could cause immediate harm to the non-breaching Party, the non-breaching Party shall be 
entitled to seek preliminary and permanent injunctive relief or other equitable relief, without the necessity of proving irreparable injury or 
actual damages or waiting for the conclusion of dispute resolution procedures under Section 14.3.2 or otherwise and without the necessity

that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on 
behalf of the Party waiving such term or condition.  The waiver by either Party of any right hereunder or of the failure to perform or of a 
breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other failure or breach by such other Party 
whether of a similar nature or otherwise.  Except as otherwise expressly provided in this Agreement, the rights and remedies provided in 
this Agreement are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available.

MODEL CLAUSES

SECTION I

Clause 1

Purpose and scope

(a)  The purpose of these standard contractual clauses is to ensure compliance with the requirements of Regulation (EU) 2016/679 of the 
European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of 
personal data and on the free movement of such data (General Data Protection Regulation) for the transfer of personal data to a 
third country.

(b)  The Parties:

(i) 

the  natural  or  legal  person(s),  public  authority/ies,  agency/ies  or  other  body/ies  (hereinafter  ‘entity/ies’)  transferring  the  

personal data, as listed in Annex I.A (hereinafter each ‘data exporter’), and

(ii)  the entity/ies in a third country receiving the personal data from the data exporter, directly or indirectly via another entity 

also Party to these Clauses, as listed in Annex I.A (hereinafter each ‘data importer’)

have agreed to these standard contractual clauses (hereinafter: ‘Clauses’).

(c)  These Clauses apply with respect to the transfer of personal data as specified in Annex I.B.

(d)  The Appendix to these Clauses containing the Annexes referred to therein forms an integral part of these Clauses.

Clause 2

Effect and invariability of the Clauses

(a)  These Clauses set out appropriate safeguards, including enforceable data subject rights and effective legal remedies, pursuant to Article 
46(1) and Article 46(2)(c) of Regulation (EU) 2016/679 and, with respect to data transfers from controllers to processors and/or 
processors to processors, standard contractual clauses pursuant to Article 28(7) of Regulation (EU) 2016/679, provided they are 
not modified, except to select the appropriate Module(s) or to add or update information in the Appendix.  This does not prevent 
the  Parties  from  including  the  standard  contractual  clauses  laid  down  in  these  Clauses  in  a  wider  contract  and/or  to  add  other 
clauses  or  additional  safeguards,  provided  that  they  do  not  contradict,  directly  or  indirectly,  these  Clauses  or  prejudice  the 
fundamental rights or freedoms of data subjects.

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
 
 
(b)  These Clauses are without prejudice to obligations to which the data exporter is subject by virtue of Regulation (EU) 2016/679.

Clause 3

Third-party beneficiaries

(a)  Data subjects may invoke and enforce these Clauses, as third-party beneficiaries, against the data exporter and/or data importer, with 

the following exceptions:

(i)  Clause 1, Clause 2, Clause 3, Clause 6, Clause 7;

(ii)  Clause 8.5 (e) and Clause 8.9(b); 

(iii)  N/A

(iv)  Clause 12(a) and (d); 

(v)  Clause 13;

(vi)  Clause 15.1(c), (d) and (e);

(vii) Clause 16(e);

(viii) 

Clause 18(a) and (b).

(b)  Paragraph (a) is without prejudice to rights of data subjects under Regulation (EU) 2016/679.

Clause 4

Interpretation

(a)  Where  these  Clauses  use  terms  that  are  defined  in  Regulation  (EU)  2016/679,  those  terms  shall  have  the  same  meaning  as  in  that  

Regulation.

(b)  These Clauses shall be read and interpreted in the light of the provisions of Regulation (EU) 2016/679.

(c)  These Clauses shall not be interpreted in a way that conflicts with rights and obligations provided for in Regulation (EU) 2016/679.

Clause 5

Hierarchy

In the event of a contradiction between these Clauses and the provisions of related agreements between the Parties, existing at the time these 
Clauses are agreed or entered into thereafter, these Clauses shall prevail.

Clause 6

Description of the transfer(s)

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
The  details  of  the  transfer(s),  and  in  particular  the  categories  of  personal  data  that  are  transferred  and  the  purpose(s)  for  which  they  are 
transferred, are specified in Annex I.B.

Clause 7 – Optional

Docking clause

(a)  An entity that is not a Party to these Clauses may, with the agreement of the Parties, accede to these Clauses at any time, either as a 

data exporter or as a data importer, by completing the Appendix and signing Annex I.A.

(b)  Once it has completed the Appendix and signed Annex I.A, the acceding entity shall become a Party to these Clauses and have the 

rights and obligations of a data exporter or data importer in accordance with its designation in Annex I.A.

(c)  The acceding entity shall have no rights or obligations arising under these Clauses from the period prior to becoming a Party.

SECTION II – OBLIGATIONS OF THE PARTIES

Clause 8

Data protection safeguards

The  data  exporter  warrants  that  it  has  used  reasonable  efforts  to  determine  that  the  data  importer  is  able,  through  the  implementation  of 
appropriate technical and organisational measures, to satisfy its obligations under these Clauses.

8.1   Purpose limitation

The data importer shall process the personal data only for the specific purpose(s) of the transfer, as set out in Annex I.B. It may 

only process the personal data for another purpose:

(i)  where it has obtained the data subject’s prior consent;

(ii)  where  necessary  for  the  establishment,  exercise  or  defence  of  legal  claims  in  the  context  of  specific  administrative,  

regulatory or judicial proceedings; or

(iii)  where necessary in order to protect the vital interests of the data subject or of another natural person.

8.2    

Transparency

(a)  In order to enable data subjects to effectively exercise their rights pursuant to Clause 10, the data importer shall inform them, 
either directly or through the data exporter:

(i)  of its identity and contact details;

(ii)  of the categories of personal data processed;

(iii)  of the right to obtain a copy of these Clauses;

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
(iv)  where  it  intends  to  onward  transfer  the  personal  data  to  any  third  party/ies,  of  the  recipient  or  categories  of  
recipients  (as  appropriate  with  a  view  to  providing  meaningful  information),  the  purpose  of  such  onward 
transfer and the ground therefore pursuant to Clause 8.7.

(b)  Paragraph  (a)  shall  not  apply  where  the  data  subject  already  has  the  information,  including  when  such  information  has  
already  been  provided  by  the  data  exporter,  or  providing  the  information  proves  impossible  or  would  involve  a 
disproportionate effort for the data importer.  In the latter case, the data importer shall, to the extent possible, make the 
information publicly available.

(c)  On request, the Parties shall make a copy of these Clauses, including the Appendix as completed by them, available to the 
data  subject  free  of  charge.    To  the  extent  necessary  to  protect  business  secrets  or  other  confidential  information, 
including personal data, the Parties may redact part of the text of the Appendix prior to sharing a copy, but shall provide a 
meaningful  summary  where  the  data  subject  would  otherwise  not  be  able  to  understand  its  content  or  exercise  his/her 
rights.  On request, the Parties shall provide the data subject with the reasons for the redactions, to the extent possible 
without revealing the redacted information.

(d)  Paragraphs  (a)  to  (c)  are  without  prejudice  to  the  obligations  of  the  data  exporter  under  Articles  13  and  14  of  Regulation  

(EU) 2016/679.

8.3   Accuracy and data minimisation

(a)  Each Party shall ensure that the personal data is accurate and, where necessary, kept up to date.  The data importer shall take 
every  reasonable  step  to  ensure  that  personal  data  that  is  inaccurate,  having  regard  to  the  purpose(s)  of  processing,  is 
erased or rectified without delay.

(b)  If  one  of  the  Parties  becomes  aware  that  the  personal  data  it  has  transferred  or  received  is  inaccurate,  or  has  become  

outdated, it shall inform the other Party without undue delay.

(c)  The data importer shall ensure that the personal data is adequate, relevant and limited to what is necessary in relation to the 

purpose(s) of processing.

8.4    

Storage limitation

The data importer shall retain the personal data for no longer than necessary for the purpose(s) for which it is processed.  It shall 
put  in  place  appropriate  technical  or  organisational  measures  to  ensure  compliance  with  this  obligation,  including  erasure  or 
anonymisation of the data and all back-ups at the end of the retention period.

8.5    

Security of processing

(a)  The data importer and, during transmission, also the data exporter shall implement appropriate technical and organisational 
measures  to  ensure  the  security  of  the  personal  data,  including  protection  against  a  breach  of  security  leading  to 
accidental 

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
or  unlawful  destruction,  loss,  alteration,  unauthorised  disclosure  or  access  (hereinafter  ‘personal  data  breach’).    In 
assessing the appropriate level of security, they shall take due account of the state of the art, the costs of implementation, 
the nature, scope, context and purpose(s) of processing and the risks involved in the processing for the data subject.  The 
Parties  shall  in  particular  consider  having  recourse  to  encryption  or  pseudonymisation,  including  during  transmission, 
where the purpose of processing can be fulfilled in that manner.

(b)  The Parties have agreed on the technical and organisational measures set out in Annex II.  The data importer shall carry out 

regular checks to ensure that these measures continue to provide an appropriate level of security.

(c)  The  data  importer  shall  ensure  that  persons  authorised  to  process  the  personal  data  have  committed  themselves  to  

confidentiality or are under an appropriate statutory obligation of confidentiality.

(d)  In the event of a personal data breach concerning personal data processed by the data importer under these Clauses, the data 
importer shall take appropriate measures to address the personal data breach, including measures to mitigate its possible 
adverse effects.

(e)  In  case  of  a  personal  data  breach  that  is  likely  to  result  in  a  risk  to  the  rights  and  freedoms  of  natural  persons,  the  data  
importer  shall  without  undue  delay  notify  both  the  data  exporter  and  the  competent  supervisory  authority  pursuant  to 
Clause  13.  Such  notification  shall  contain  i)  a  description  of  the  nature  of  the  breach  (including,  where  possible, 
categories and approximate number of data subjects and personal data records concerned), ii) its likely consequences, iii) 
the measures taken or proposed to address the breach, and iv) the details of a contact point from whom more information 
can be obtained.  To the extent it is not possible for the data importer to provide all the information at the same time, it 
may do so in phases without undue further delay.

(f) 

In case of a personal data breach that is likely to result in a high risk to the rights and freedoms of natural persons, the data 
importer shall also notify without undue delay the data subjects concerned of the personal data breach and its nature, if 
necessary in cooperation with the data exporter, together with the information referred to in paragraph (e), points ii) to 
iv),  unless  the  data  importer  has  implemented  measures  to  significantly  reduce  the  risk  to  the  rights  or  freedoms  of 
natural persons, or notification would involve disproportionate efforts.  In the latter case, the data importer shall instead 
issue a public communication or take a similar measure to inform the public of the personal data breach.

(g)  The data importer shall document all relevant facts relating to the personal data breach, including its effects and any remedial 

action taken, and keep a record thereof.

8.6   Sensitive data

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
Where the transfer involves personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, or 
trade union membership, genetic data, or biometric data for the purpose of uniquely identifying a natural person, data concerning 
health or a person’s sex life or sexual orientation, or data relating to criminal convictions or offences (hereinafter ‘sensitive data’), 
the data importer shall apply specific restrictions and/or additional safeguards adapted to the specific nature of the data and the 
risks  involved.    This  may  include  restricting  the  personnel  permitted  to  access  the  personal  data,  additional  security  measures 
(such as pseudonymisation) and/or additional restrictions with respect to further disclosure.

8.7    

Onward transfers

The data importer shall not disclose the personal data to a third party located outside the European Union (in the same country as 
the data importer or in another third country, hereinafter ‘onward transfer’) unless the third party is or agrees to be bound by these 
Clauses, under the appropriate Module.  Otherwise, an onward transfer by the data importer may only take place if:

(i) 

it is to a country benefitting from an adequacy decision pursuant to Article 45 of Regulation (EU) 2016/679 that covers the 

onward transfer;

(ii)  the  third  party  otherwise  ensures  appropriate  safeguards  pursuant  to  Articles  46  or  47  of  Regulation  (EU)  2016/679  with  

respect to the processing in question;

(iii)  the third party enters into a binding instrument with the data importer ensuring the same level of data protection as under 

these Clauses, and the data importer provides a copy of these safeguards to the data exporter;

(iv)  it is necessary for the establishment, exercise or defence of legal claims in the context of specific administrative, regulatory 

or judicial proceedings;

(v) 

it is necessary in order to protect the vital interests of the data subject or of another natural person; or

(vi)  where  none  of  the  other  conditions  apply,  the  data  importer  has  obtained  the  explicit  consent  of  the  data  subject  for  an  
onward transfer in a specific situation, after having informed him/her of its purpose(s), the identity of the recipient and 
the possible risks of such transfer to him/her due to the lack of appropriate data protection safeguards.  In this case, the 
data importer shall inform the data exporter and, at the request of the latter, shall transmit to it a copy of the information 
provided to the data subject.

Any onward transfer is subject to compliance by the data importer with all the other safeguards under these Clauses, in particular 
purpose limitation.

8.8    

Processing under the authority of the data importer 

The  data  importer  shall  ensure  that  any  person  acting  under  its  authority,  including  a  processor,  processes  the  data  only  on  its 
instructions.

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
8.9    

Documentation and compliance

(a)  Each Party shall be able to demonstrate compliance with its obligations under these Clauses.  In particular, the data importer 

shall keep appropriate documentation of the processing activities carried out under its responsibility.

(b)  The data importer shall make such documentation available to the competent supervisory authority on request.

Clause 9

Use of sub-processors

N/A

Clause 10

Data subject rights

 (a)  The data importer, where relevant with the assistance of the data exporter, shall deal with any enquiries and requests it receives from a 
data subject relating to the processing of his/her personal data and the exercise of his/her rights under these Clauses without undue 
delay and at the latest within one month of the receipt of the enquiry or request.  The data importer shall take appropriate measures 
to facilitate such enquiries, requests and the exercise of data subject rights.  Any information provided to the data subject shall be 
in an intelligible and easily accessible form, using clear and plain language.

(b)  In particular, upon request by the data subject the data importer shall, free of charge:

(i)  provide confirmation to the data subject as to whether personal data concerning him/her is being processed and, where this is 
the  case,  a  copy  of  the  data  relating  to  him/her  and  the  information  in  Annex  I;  if  personal  data  has  been  or  will  be 
onward transferred, provide information on recipients or categories of recipients (as appropriate with a view to providing 
meaningful information) to which the personal data has been or will be onward transferred, the purpose of such onward 
transfers  and  their  ground  pursuant  to  Clause  8.7;  and  provide  information  on  the  right  to  lodge  a  complaint  with  a 
supervisory authority in accordance with Clause 12(c)(i);

(ii)  rectify inaccurate or incomplete data concerning the data subject;

(iii)  erase  personal  data  concerning  the  data  subject  if  such  data  is  being  or  has  been  processed  in  violation  of  any  of  these  
Clauses ensuring third-party beneficiary rights, or if the data subject withdraws the consent on which the processing is 
based.

(c)  Where the data importer processes the personal data for direct marketing purposes, it shall cease processing for such purposes if the 

data subject objects to it.

(d)  The  data  importer  shall  not  make  a  decision  based  solely  on  the  automated  processing  of  the  personal  data  transferred  (hereinafter  
‘automated  decision’),  which  would  produce  legal  effects  concerning  the  data  subject  or  similarly  significantly  affect  him/her, 
unless with the 

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
explicit consent of the data subject or if authorised to do so under the laws of the country of destination, provided that such laws 
lays down suitable measures to safeguard the data subject’s rights and legitimate interests.  In this case, the data importer shall, 
where necessary in cooperation with the data exporter:

(i) 

inform the data subject about the envisaged automated decision, the envisaged consequences and the logic involved; and

(ii)  implement suitable safeguards, at least by enabling the data subject to contest the decision, express his/her point of view and 

obtain review by a human being.

(e)  Where  requests  from  a  data  subject  are  excessive,  in  particular  because  of  their  repetitive  character,  the  data  importer  may  either  
charge a reasonable fee taking into account the administrative costs of granting the request or refuse to act on the request.

(f)  The data importer may refuse a data subject’s request if such refusal is allowed under the laws of the country of destination and is 
necessary  and  proportionate  in  a  democratic  society  to  protect  one  of  the  objectives  listed  in  Article  23(1)  of  Regulation  (EU) 
2016/679.

(g)  If  the  data  importer  intends  to  refuse  a  data  subject’s  request,  it  shall  inform  the  data  subject  of  the  reasons  for  the  refusal  and  the  

possibility of lodging a complaint with the competent supervisory authority and/or seeking judicial redress.

Clause 11

Redress

(a)  The data importer shall inform data subjects in a transparent and easily accessible format, through individual notice or on its website, 

of a contact point authorised to handle complaints.  It shall deal promptly with any complaints it receives from a data subject.

(b)  In case of a dispute between a data subject and one of the Parties as regards compliance with these Clauses, that Party shall use its best 
efforts  to  resolve  the  issue  amicably  in  a  timely  fashion.    The  Parties  shall  keep  each  other  informed  about  such  disputes  and, 
where appropriate, cooperate in resolving them.

(c)  Where the data subject invokes a third-party beneficiary right pursuant to Clause 3, the data importer shall accept the decision of the 

data subject to:

(i) 

lodge a complaint with the supervisory authority in the Member State of his/her habitual residence or place of work, or the 

competent supervisory authority pursuant to Clause 13;

(ii)  refer the dispute to the competent courts within the meaning of Clause 18.

(d)  The Parties accept that the data subject may be represented by a not-for-profit body, organisation or association under the conditions 

set out in Article 80(1) of Regulation (EU) 2016/679.

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
(e)  The data importer shall abide by a decision that is binding under the applicable EU or Member State law.

(f)  The data importer agrees that the choice made by the data subject will not prejudice his/her substantive and procedural rights to seek 

remedies in accordance with applicable laws.

Clause 12

Liability

 (a)  Each Party shall be liable to the other Party/ies for any damages it causes the other Party/ies by any breach of these Clauses.

(b)  Each Party shall be liable to the data subject, and the data subject shall be entitled to receive compensation, for any material or non-
material damages that the Party causes the data subject by breaching the third-party beneficiary rights under these Clauses.  This is 
without prejudice to the liability of the data exporter under Regulation (EU) 2016/679.

(c)  Where  more  than  one  Party  is  responsible  for  any  damage  caused  to  the  data  subject  as  a  result  of  a  breach  of  these  Clauses,  all  
responsible Parties shall be jointly and severally liable and the data subject is entitled to bring an action in court against any of 
these Parties.

(d)  The Parties agree that if one Party is held liable under paragraph (c), it shall be entitled to claim back from the other Party/ies that part 

of the compensation corresponding to its/their responsibility for the damage.

(e)  The data importer may not invoke the conduct of a processor or sub-processor to avoid its own liability.

Clause 13

Supervision

(a)

[Where the data exporter is established in an EU Member State:] The supervisory authority with responsibility for ensuring 
compliance by the data exporter with Regulation (EU) 2016/679 as regards the data transfer, as indicated in Annex I.C, shall act as 
competent supervisory authority.
[Where the data exporter is not established in an EU Member State, but falls within the territorial scope of application of 
Regulation (EU) 2016/679 in accordance with its Article 3(2) and has appointed a representative pursuant to Article 27(1) 
of Regulation (EU) 2016/679:] The supervisory authority of the Member State in which the representative within the meaning of 
Article 27(1) of Regulation (EU) 2016/679 is established, as indicated in Annex I.C, shall act as competent supervisory authority.
[Where the data exporter is not established in an EU Member State, but falls within the territorial scope of application of 
Regulation (EU) 2016/679 in accordance with its Article 3(2) without however having to appoint a representative pursuant 
to Article 27(2) of Regulation (EU) 2016/679:] The supervisory authority of one of the Member States in which the data subjects 
whose personal data is transferred under these Clauses in 

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
relation to the offering of goods or services to them, or whose behaviour is monitored, are located, as indicated in Annex I.C, shall 
act as competent supervisory authority. 

(b)  The  data  importer  agrees  to  submit  itself  to  the  jurisdiction  of  and  cooperate  with  the  competent  supervisory  authority  in  any  
procedures  aimed  at  ensuring  compliance  with  these  Clauses.    In  particular,  the  data  importer  agrees  to  respond  to  enquiries, 
submit  to  audits  and  comply  with  the  measures  adopted  by  the  supervisory  authority,  including  remedial  and  compensatory 
measures.  It shall provide the supervisory authority with written confirmation that the necessary actions have been taken.

SECTION III – LOCAL LAWS AND OBLIGATIONS IN CASE OF ACCESS BY PUBLIC AUTHORITIES

Clause 14

Local laws and practices affecting compliance with the Clauses

 (a)  The Parties warrant that they have no reason to believe that the laws and practices in the third country of destination applicable to the 
processing of the personal data by the data importer, including any requirements to disclose personal data or measures authorising 
access  by  public  authorities,  prevent  the  data  importer  from  fulfilling  its  obligations  under  these  Clauses.    This  is  based  on  the 
understanding that laws and practices that respect the essence of the fundamental rights and freedoms and do not exceed what is 
necessary and proportionate in a democratic society to safeguard one of the objectives listed in Article 23(1) of Regulation (EU) 
2016/679, are not in contradiction with these Clauses.

(b)  The  Parties  declare  that  in  providing  the  warranty  in  paragraph  (a),  they  have  taken  due  account  in  particular  of  the  following  

elements:

(i) 

the specific circumstances of the transfer, including the length of the processing chain, the number of actors involved and the 
transmission channels  used;  intended  onward  transfers;  the  type  of  recipient;  the purpose of processing; the categories 
and format of the transferred personal data; the economic sector in which the transfer occurs; the storage location of the 
data transferred;

(ii)  the  laws  and  practices  of  the  third  country  of  destination–  including  those  requiring  the  disclosure  of  data  to  public  
authorities or authorising access by such authorities – relevant in light of the specific circumstances of the transfer, and 
the applicable limitations and safeguards;

(iii)  any  relevant  contractual,  technical  or  organisational  safeguards  put  in  place  to  supplement  the  safeguards  under  these  
Clauses,  including  measures  applied  during  transmission  and  to  the  processing  of  the  personal  data  in  the  country  of 
destination.

(c)  The data importer warrants that, in carrying out the assessment under paragraph (b), it has made its best efforts to provide the data 
exporter with relevant information and agrees that it will continue to cooperate with the data exporter in ensuring compliance with 
these Clauses.

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
(d)  The Parties agree to document the assessment under paragraph (b) and make it available to the competent supervisory authority on 

request.

(e)  The  data  importer  agrees  to  notify  the  data  exporter  promptly  if,  after  having  agreed  to  these  Clauses  and  for  the  duration  of  the  
contract,  it  has  reason  to  believe  that  it  is  or  has  become  subject  to  laws  or  practices  not  in  line  with  the  requirements  under 
paragraph (a), including following a change in the laws of the third country or a measure (such as a disclosure request) indicating 
an application of such laws in practice that is not in line with the requirements in paragraph (a). 

(f)  Following a notification pursuant to paragraph (e), or if the data exporter otherwise has reason to believe that the data importer can no 
longer fulfil its obligations under these Clauses, the data exporter shall promptly identify appropriate measures (e.g. technical or 
organisational measures to ensure security and confidentiality) to be adopted by the data exporter and/or data importer to address 
the situation.  The data exporter shall suspend the data transfer if it considers that no appropriate safeguards for such transfer can 
be  ensured,  or  if  instructed  by  the  competent  supervisory  authority  to  do  so.    In  this  case,  the  data  exporter  shall  be  entitled  to 
terminate the contract, insofar as it concerns the processing of personal data under these Clauses.  If the contract involves more 
than two Parties, the data exporter may exercise this right to termination only with respect to the relevant Party, unless the Parties 
have agreed otherwise.  Where the contract is terminated pursuant to this Clause, Clause 16(d) and (e) shall apply.

Clause 15

Obligations of the data importer in case of access by public authorities

15.1     Notification

(a)  The data importer agrees to notify the data exporter and, where possible, the data subject promptly (if necessary with the 

help of the data exporter) if it:

(i) 

receives  a  legally  binding  request  from  a  public  authority,  including  judicial  authorities,  under  the  laws  of  the  
country of destination for the disclosure of personal data transferred pursuant to these Clauses; such notification 
shall  include  information  about  the  personal  data  requested,  the  requesting  authority,  the  legal  basis  for  the 
request and the response provided; or

(ii)  becomes aware of any direct access by public authorities to personal data transferred pursuant to these Clauses in 
accordance with the laws of the country of destination; such notification shall include all information available 
to the importer.

(b)  If the data importer is prohibited from notifying the data exporter and/or the data subject under the laws of the country of 
destination,  the  data  importer  agrees  to  use  its  best  efforts  to  obtain  a  waiver  of  the  prohibition,  with  a  view  to 
communicating as much information as possible, as soon as possible.  The data importer agrees to 

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
document its best efforts in order to be able to demonstrate them on request of the data exporter.

(c)  Where  permissible  under  the  laws  of  the  country  of  destination,  the  data  importer  agrees  to  provide  the  data  exporter,  at  
regular intervals for the duration of the contract, with as much relevant information as possible on the requests received 
(in particular, number of requests, type of data requested, requesting authority/ies, whether requests have been challenged 
and the outcome of such challenges, etc.). 

(d)  The data importer agrees to preserve the information pursuant to paragraphs (a) to (c) for the duration of the contract and 

make it available to the competent supervisory authority on request.

(e)  Paragraphs (a) to (c) are without prejudice to the obligation of the data importer pursuant to Clause 14(e) and Clause 16 to 

inform the data exporter promptly where it is unable to comply with these Clauses.

15.2     Review of legality and data minimisation

(a)  The  data  importer  agrees  to  review  the  legality  of  the  request  for  disclosure,  in  particular  whether  it  remains  within  the  
powers granted to the requesting public authority, and to challenge the request if, after careful assessment, it concludes 
that there are reasonable grounds to consider that the request is unlawful under the laws of the country of destination, 
applicable obligations under international law and principles of international comity.  The data importer shall, under the 
same  conditions,  pursue  possibilities  of  appeal.    When  challenging  a  request,  the  data  importer  shall  seek  interim 
measures with a view to suspending the effects of the request until the competent judicial authority has decided on its 
merits.    It  shall  not  disclose  the  personal  data  requested  until  required  to  do  so  under  the  applicable  procedural  rules.  
These requirements are without prejudice to the obligations of the data importer under Clause 14(e).

(b)  The data importer agrees to document its legal assessment and any challenge to the request for disclosure and, to the extent 
permissible under the laws of the country of destination, make the documentation available to the data exporter.  It shall 
also make it available to the competent supervisory authority on request. 

(c)  The  data  importer  agrees  to  provide  the  minimum  amount  of  information  permissible  when  responding  to  a  request  for  

disclosure, based on a reasonable interpretation of the request.

SECTION IV – FINAL PROVISIONS

Clause 16

Non-compliance with the Clauses and termination

(a)  The data importer shall promptly inform the data exporter if it is unable to comply with these Clauses, for whatever reason.

|[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10). Such excluded information is not material and would likely 
cause competitive harm to the registrant if publicly disclosed.||

 
 
(b)  In the event that the data importer is in breach of these Clauses or unable to comply with these Clauses, the data exporter shall suspend 
the transfer of personal data to the data importer until compliance is again ensured or the contract is terminated.  This is without 
prejudice to Clause 14(f).

(c)  The data exporter shall be entitled to terminate the contract, insofar as it concerns the processing of personal data under these Clauses, 

where:

(i) 

the data exporter has suspended the transfer of personal data to the data importer pursuant to paragraph (b) and compliance 

with these Clauses is not restored within a reasonable time and in any event within one month of suspension;

(ii)  the data importer is in substantial or persistent breach of these Clauses; or

(iii)  the  data  importer  fails  to  comply  with  a  binding  decision  of  a  competent  court  or  supervisory  authority  regarding  its  

obligations under these Clauses.

In  these  cases,  it  shall  inform  the  competent  supervisory  authority  of  such  non-compliance.    Where  the  contract  involves  more 
than two Parties, the data exporter may exercise this right to termination only with respect to the relevant Party, unless the Parties 
have agreed otherwise.

(d)  Personal data that has been transferred prior to the termination of the contract pursuant to paragraph (c) shall at the choice of the data 
exporter immediately be returned to the data exporter or deleted in its entirety.  The same shall apply to any copies of the data.  
The data importer shall certify the deletion of the data to the data exporter.  Until the data is deleted or returned, the data importer 
shall  continue  to  ensure  compliance  with  these  Clauses.    In  case  of  local  laws  applicable  to  the  data  importer  that  prohibit  the 
return or deletion of the transferred personal data, the data importer warrants that it will continue to ensure compliance with these 
Clauses and will only process the data to the extent and for as long as required under that local law.

(e)  Either Party may revoke its agreement to be bound by these Clauses where (i) the European Commission adopts a decision pursuant to 
Article  45(3)  of  Regulation  (EU)  2016/679  that  covers  the  transfer  of  personal  data  to  which  these  Clauses  apply;  or  (ii) 
Regulation (EU) 2016/679 becomes part of the legal framework of the country to which the personal data is transferred.  This is 
without prejudice to other obligations applying to the processing in question under Regulation (EU) 2016/679.

Clause 17

Governing law

These Clauses shall be governed by the law of one of the EU Member States, provided such law allows for third-party beneficiary rights.

EXPLANATORY NOTE:

It must be possible to clearly distinguish the information applicable to each transfer or category of transfers and, in this regard, to determine 
the respective role(s) of the Parties as data exporter(s) and/or data importer(s).  This does not necessarily require completing and signing 
separate  appendices  for  each  transfer/category  of  transfers  and/or  contractual  relationship,  where  this  transparency  can  achieved  through 
one appendix.  However, where necessary to ensure sufficient clarity, separate appendices should be used.

any  extension  rights  described  in  Paragraph  3.2,  below,  and  (ii)  earlier  termination  by  Landlord,  as  provided  in  this  Lease.    The  term 
“Expiration Date”, as used in this Lease, shall mean the Initial Expiration Date, any earlier date upon which this Lease is terminated by 
Landlord,  as  provided  below,  or  if  the  Term  is  extended  pursuant  to  Paragraph  3.2,  below,  then  the  expiration  date  of  any  exercised 
Extension Term.

3.2. Extension Rights. Tenant shall, subject to all of the provisions of this Paragraph 3.2 (including all subparagraphs 
hereof), have one (1) option to extend the Term (the “Option to Extend”) for an additional term of three (3) years (the "Extension Term"), 
provided Tenant or a Permitted Transferee is in occupancy 90% of the Premises at the time of exercise of the Option to Extend and Tenant 
gives  Landlord  written  notice  via  overnight  nationally-recognized  courier  (such  as  FedEx  or  UPS),  with  signature  acknowledgement  by 
recipient required, of its election to exercise such Option to Extend no less than 12 months and no more than 15 months prior to the then-
applicable Expiration Date of the Term.  Such notice will constitute Tenant’s binding irrevocable election to extend the Term pursuant to this 
Paragraph  3.2  and  may  not  subsequently  be  revoked  by  Tenant  except  as  provided  below.    Time  is  of  the  essence  with  respect  to  the 
timing of such requirement to give notice to Landlord.

3.2.1.Restrictions on Transferability of Option.  The Option to Extend is personal to the Tenant originally named 
in  this  Lease  or  any  Permitted  Transferee  (as  defined  below)  and  may  not  be  exercised  by  anyone  other  than  such  originally  named 
Tenant or a Permitted Transferee. 

3.2.2.Conditions  Terminating  Tenant’s  Rights  to  Exercise  Option.  Tenant shall not have the right to exercise 
the Option to Extend, notwithstanding anything set forth above to the contrary: (a) during any period of time commencing from the date 
Landlord  gives  to  Tenant  a  bona  fide  written  notice  that  Tenant  is  in  default  under  any  provision  of  this  Lease  and  continuing  until  the 
default alleged in said notice is cured; or (b) during the period of time commencing on the day after a monetary obligation to Landlord is 
due from Tenant and unpaid (without any necessity for notice thereof to Tenant) and continuing until the obligation is paid. The period of 
time within which the Option to Extend may be exercised shall not be extended or lengthened by reason of Tenant’s inability to exercise 
the Option to Extend because of the foregoing provisions of this Paragraph 3.2.2, even if the effect thereof is to eliminate Tenant’s right to 
exercise the Option to Extend.

3.2.3.Conditions Terminating Tenant’s Option Rights.  All rights with respect to the Option to Extend (including 
rights  as  to  subsequent  Extension  Terms,  if  any)  shall  terminate  and  be  of  no  further  force  or  effect  even  after  Tenant’s  due  and  timely 
exercise of the Option to Extend, if, as of the date of the commencement of the Extension Term, Tenant is in default of its obligations under 
this Lease beyond any applicable notice and cure period.

3.2.4.Terms and Conditions of Extension of Term.  If Tenant duly and timely exercises the Option to Extend for 
an  Extension  Term,  then  this  Lease  shall  remain  in  full  force  and  effect  for  such  additional  three  (3)  year  period,  except  that  the  Basic 
Monthly  Rent  will  adjust  as  of  the  first  day  of  the  first  Extension  Term  such  that  for  the  first  year  of  the  first  Extension  Term  the  Basic 
Monthly Rent shall be equal to the then prevailing base rental rate (adjusted to account for tenant improvement and similar refurbishment 
or construction allowances, free rent, periods and other tenant benefits/concessions typically associated with a renewal lease) for renewal 
leases of comparable Class A office space of comparable size, location, quality, views and Project amenities (i.e., staffed fitness center, 
conference  center,  daycare  center  and  multiple  food  and  beverage  offerings)  in  the  Carmel  Valley/Del  Mar  Heights  submarket,  as 
projected  for  the  first  day  of  the  applicable  Extension  Term  and  determined  pursuant  to  Paragraph  3.2.5,  below  (the  "Then-Prevailing 
Rate"). 

3.2.5.Determination  of  Then-Prevailing  Rate.    If  Tenant  properly  exercises  the  Option  to  Extend  for  an 
Extension  Term,  then  Landlord  shall,  subject  to  the  terms  and  conditions  set  forth  in  this  Paragraph  3.2,  within  15  business  days  after 
receipt of Tenant's Option Exercise Notice, provide Tenant with written notice of the Then-Prevailing Rate and the Then-Prevailing Increase 
Rate and the calculation of the new Basic Monthly Rent to be effective during the first year of the Extension Term. Tenant shall have 10 
business  days  from  the  date  of  Landlord's  notice  in  which  to  (i)  accept  the  Landlord's  determination  of  the  Then-Prevailing  Rate,  or  (ii) 
dispute  Landlord's  determination  of  the  Then-Prevailing  Rate.  If  Tenant  fails  to  notify  Landlord,  in  writing,  of  its  disagreement  with 
Landlord's determination of the Then-Prevailing Rate within such 10 business day period, then Tenant will be deemed to have accepted 
Landlord's  determination  and  Landlord's  determination  shall  be  binding  on  both  parties.  If  Tenant  disputes  such  determination,  then  its 
notice  to  Landlord  disputing  such  determination  must  set  forth  Tenant's  determination  of  the  Then-Prevailing  Rate.  Upon  receipt  of 
Tenant's notice, Landlord and Tenant shall promptly meet and, in good faith, attempt to agree upon the Then-Prevailing 

American Assets Trust – Lease Form 1/31/2023

Rate. If Landlord and Tenant are unable to reach agreement upon the Then-Prevailing Rate within 30 days of the date of Landlord's receipt 
of  Tenant's  dispute  notice,  then  the  parties  shall  promptly  submit  such  dispute  to  the  San  Diego  office  of  the  American  Arbitration 
Association  (the  "AAA"),  or  its  successor,  for  resolution  before  a  single  arbitrator  (who  must  have  at  least  ten  years'  experience  in  the 
Carmel Valley/Del Mar Heights commercial real estate market as a real estate broker or MAI appraiser) in accordance with Real Estate 
Industry Arbitration Rules of the AAA. Within 10 days of the commencement of the arbitration, Landlord and Tenant shall each provide the 
arbitrator  with  their  respective  written  determination  of  the  Then-Prevailing  Rate—which  determinations  will  not  be  disclosed  by  the 
arbitrator until both parties have submitted their respective written determinations. The arbitrator's sole authority will be to select between 
the Landlord's and the Tenant's respective written determinations of the Then-Prevailing Rate, as provided to the arbitrator in accordance 
with the preceding sentence; provided, however, if either party fails to timely submit such a written determination to the arbitrator, then the 
arbitrator shall use the written determination of such party as set forth in the notices described above as part of the initiation of the subject 
process. In no event may such arbitrator select any other amount as the Then-Prevailing Rate. The decision of the arbitrator shall be final 
and  binding  upon  all  parties,  and  not  subject  to  appeal,  and  the  cost  of  the  arbitration  and  the  arbitrator’s  fee  shall  be  shared  equally 
between Landlord and Tenant.

4. Delivery of Possession.

4.1. Delivery  Requirements.    On  or  before  the  Lease  Commencement  Date,  Landlord,  at  its  cost,  shall  have 
Substantially Completed the work, if any, required to be completed by Landlord prior to the tender of possession of the Premises to Tenant, 
as described in Exhibit “C” to this Lease (“Landlord's Work”) and shall tender possession of the Premises to Tenant (subject to Landlord's 
reserved  rights  hereunder  and  Landlord's  right  to  continue  the  completion  of  Landlord's  Work  without  material  interference  by  Tenant).  
Landlord's tender of possession of the Premises shall consist of Landlord's notification (which notification may be telephonic, by written 
notice,  or  by  electronic  transmission—such  as  by  facsimile  or  email)  that  possession  of  the  Premises  is  then  available  to  Tenant,  and 
instructing  Tenant  that  Tenant  may  obtain  the  keys  to  the  Premises  from  Landlord's  offices.  Tenant's  refusal  to  accept  such  tender  (or 
avoidance  thereof)  shall  not  affect  the  Lease  Commencement  Date  or  delay  the  Rent  Commencement  Date  and  such  dates  will  be 
calculated  as  if  no  such  refusal  or  avoidance  had  occurred.    Pursuant  to  the  provisions  of  attached  Exhibit  "C",  following  the  Lease 
Commencement  Date,  Landlord  shall  provide  Tenant  with  a  factually  accurate  "Confirmation  of  Lease  Terms"  (herein  so  called)  written 
memorandum in the form of attached hereto as Exhibit "H"; provided, however, that any failure by Landlord to provide the Confirmation of 
Lease Terms shall not affect the validity or enforceability of this Lease or any of the provisions hereof. Tenant shall execute and return to 
Landlord  the  Confirmation  of  Lease  Terms  memorandum  within  10  days  after  its  submittal  by  Landlord  to  Tenant.    Failure  by  Tenant  to 
execute the Confirmation of Lease Terms memorandum shall not amend or in any way affect the terms thereof, but shall be deemed as 
Tenant's final and conclusive acceptance of the terms of the Confirmation of Lease Terms.

4.2. Definition  of  Substantial  Completion.    For  purposes  of  this  Lease,  the  term  “Substantially  Complete”  (and  its 
grammatical variations, such as Substantial Completion) when used with reference to Landlord's Work, will mean that Landlord's Work has 
been completed in the Premises pursuant to Exhibit "C", with the exception of any punch list items of a minor nature that do not interfere 
with Tenant’s ability to complete Tenant’s Work and may be finally completed within thirty (30) days by Landlord.

4.3.

Final Completion.  Except for any items set forth on a written, detailed “punch-list” of excepted items delivered to 
Landlord  upon  the  Lease  Commencement  Date,  and  subject  to  the  terms  of  this  Lease,  Tenant  shall,  as  of  the  Lease  Commencement 
Date, be deemed to have (i) determined that, to Tenant's knowledge, the Premises comply with all applicable Laws and ordinances, and 
that  the  Premises  are  in  first-class  condition  and  repair,  (ii)  acknowledged  that  Landlord's  Work  has  been  Substantially  Completed,  (iii) 
accepted the Premises in its then as-is condition with no right to require Landlord to perform any additional work therein, except as set 
forth on the punch list, and (iv) waived any express or implied warranties regarding the condition of the Premises, including any implied 
warranties of fitness for a particular purpose or habitability, suitability, merchantability, quality or condition.   

5. Use of Premises and Common Areas.

5.1. Permitted Use of Premises.  Tenant may use the Premises for the Permitted Use specified in the Principal Lease 
Provisions  and  for  no  other  use  without  Landlord’s  consent.    Any  change  or  deviation  in  the  Permitted  Use  will  require  Landlord's  prior 
written consent, which consent may be granted or withheld in Landlord's sole and exclusive discretion.

5.2. Compliance with Laws.  Landlord covenants that the Premises will comply with the Americans With Disabilities 
Act of 1990, as amended (42 U.S.C. 12181 et seq.) (the “ADA”) and all other applicable federal, state and local laws, statutes, ordinances, 
or  other  governmental  rules,  regulations  or  requirements  (collectively,  together  with  the  ADA,  “Laws”)  as  of  the  Lease  Commencement 
Date.  After the Lease Commencement Date, Tenant shall comply with all Laws with respect to Tenant's particular use of the Premises, 
Tenant’s Work or any Alterations.  Such obligation to comply with Laws shall include without limitation compliance with the ADA and the 
California  Unruh  Civil  Rights  Act.    In  addition  to  the  foregoing,  if  Tenant's  particular  use  of  the  Premises  (including  the  construction  or 
installation of Tenant’s Work, Alterations, as defined below) or any modifications to Tenant’s use of the Premises or Project results in the 
need for modifications or alterations to any other portion of the Project (including but not limited to the Common Areas of the Project) in 
order to comply with the ADA or other applicable Laws, then Tenant shall additionally be responsible, upon demand, for the cost of such 
modifications and alterations plus a supervisory fee of 10% of such cost payable to Landlord. Tenant acknowledges and agrees that it has 
reviewed the CASp Inspection Disclosure and Acknowledgment attached to this Lease as Exhibit “F”, and California Civil Code Section 
1938, attached thereto and incorporated herein, at least 48 hours prior to the execution of this Lease.  Tenant shall indemnify, defend (with 
counsel reasonably satisfactory to Landlord), and hold Landlord (and its partners, members, shareholders, directors, officers, employees, 
agents, assigns, and any successors to Landlord's interest in the Project) harmless from and against any and all losses, costs, demands, 
damages,  expenses  (including  reasonable  attorneys'  fees  and  expenses),  claims,  causes  of  action,  judgments,  penalties,  fines,  or 
liabilities, to the extent arising from Tenant's failure to satisfy its obligations under this Paragraph including, without limitation, (i) any costs, 
expenses, and liabilities incurred by Landlord in connection with responding to any demand by any governmental authority that Landlord 
undertake any modifications or alterations which are Tenant's responsibility pursuant to this Paragraph  or for which Tenant is obligated to 
reimburse Landlord hereunder, as well as (ii) any attorneys' fees, costs, expenses, and liabilities incurred by Landlord in responding to, 
defending, pursuing, or otherwise being involved with any action, suit, or proceeding arising out of any claim relating to the non-compliance 
of the Premises or the Project with the ADA or any similar Laws where such action, suit, or proceeding relates to, or arises from, Tenant's 
particular use of the Premises, Tenant’s Work or any Alterations.

5.3. Condition During Periods of Non-Use.  During any period of time in which Tenant is not continuously using and 
occupying the Premises for the operation of its business, Tenant shall take such measures as may be necessary or desirable, in Landlord's 
reasonable opinion, to secure the Premises from break-ins and use by unauthorized persons, to minimize the appearance of non-use, and 
to otherwise maintain the interior portions of Tenant's Premises, including all windows and doors, in first class condition. 

5.4. Use  of  Common  Areas.  Tenant's  use  of  the  Common  Areas  shall  at  all  times  comply  with  the  provisions  of  all 
Rules  (as  defined  below)  regarding  such  use  as  Landlord  may  from  time  to  time  adopt  which  do  not  materially  increase  Tenant's 
obligations or materially decrease Tenant's rights under the Lease. In no event shall the rights granted to Tenant to use the Common Areas 
include  the  right  to  store  any  property  in  the  Common  Areas,  whether  temporarily  or  permanently.  Any  property  stored  in  the  Common 
Areas may be removed by Landlord and disposed of, and the cost of such removal and disposal shall be payable by Tenant to Landlord 
upon  demand.  Additionally,  in  no  event  may  Tenant  use  any  portion  of  the  Common  Areas  for  loading,  unloading,  or  parking,  except  in 
those  areas  specifically  designated  by  Landlord  for  such  purposes,  nor  for  any  group  social  event,  sidewalk  sale,  employment  fair  or 
similar commercial or unauthorized purpose. Without limiting the generality of the rights of Landlord under this Paragraph 5.4, Landlord 
also reserves the right to temporarily close any portion of the Common Areas for maintenance purposes so long as reasonable access to 
the Premises remains available.

5.5. General Covenants and Limitations on Use.  In addition to the Rules, Tenant’s and Tenant's agents’, employees’, 
officers’, independent contractors’, licensees’, guests and invitees’ (collectively, “Tenant's Invitees”) use of the Premises and the Project, 
will be subject to the following additional general covenants and limitations on use. 

5.5.1.Tenant shall not do, bring, or keep anything in or about the Premises that will cause a cancellation of any 
insurance covering the Premises.  If the rate of any insurance carried by Landlord is increased as a result of Tenant's use of the Premises 
or Tenant’s failure to continuously use and occupy the Premises, Tenant shall pay the amount of such increase to Landlord, within 10 days 
after Landlord delivers to Tenant a notice of such increase.  

5.5.2.No noxious or unreasonably offensive activity shall be carried on, in or upon the Premises by Tenant or 
Tenant's  Invitees,  nor  shall  anything  be  done  or  kept  in  the  Premises  which  may  be  or  become  a  public  nuisance  or  which  may  cause 
unreasonable

embarrassment, disturbance, or annoyance to others in the Project, or on adjacent or nearby property.  To that end, Tenant additionally 
covenants  and  agrees  that  no  light  shall  be  emitted  from  the  Premises  which  is  unreasonably  bright  or  causes  unreasonable  glare;  no 
sounds  shall  be  emitted  from  the  Premises  which  are  unreasonably  loud  or  annoying;  and  no  odor  shall  be  emitted  from  the  Premises 
which is or might be noxious or offensive to others in the Building, on the Project, or on adjacent or near-by property. 

5.5.3.No unsightliness shall be permitted in the Premises which is visible from the Common Areas.  Without 
limiting the generality of the foregoing, all equipment, objects, and materials shall be kept enclosed within the Premises and screened from 
view or in Common Areas trash enclosures; no refuse, scraps, debris, garbage, trash, bulk materials, or waste shall be kept, stored, or 
allowed  to  accumulate  except  as  may  be  properly  enclosed  within  appropriate  containers  in  the  Premises  and  promptly  and  properly 
disposed of.

5.5.4.The  Premises  shall  not  be  used  for  sleeping  or  washing  clothes,  nor  shall  the  Premises  be  used  for 
cooking or the preparation, manufacture, or mixing of anything that might emit any offensive odor or objectionable noises or lights onto the 
Project or nearby properties.  

5.5.5.All pipes, wires, conduit, cabling, poles, antennas, and other equipment/facilities for or relating to utilities, 
telecommunications,  computer  equipment,  or  the  transmission  or  reception  of  audio  or  visual  signals  must  be  kept  and  maintained 
enclosed  within  the  Premises  (except  to  the  extent  included  as  part  of  Landlord's  Work,  Tenant's  Work,  or  otherwise  approved  by 
Landlord). 

(excluding service animals), bird, reptile, or other exotic creature in the Premises.  

5.5.6.Tenant  shall  not  keep  or  permit  to  be  kept  any  bicycle,  motorcycle,  or  other  vehicle,  nor  any  animal 

5.5.7.Neither  Tenant  nor  Tenant's  Invitees  shall  do  anything  that  will  cause  damage  or  waste  to  the  Project.  
Neither  the  floor  nor  any  other  portion  of  the  Premises  shall  be  overloaded.    Tenant  shall  be  responsible  for  all  structural  engineering 
required  to  determine  structural  load  for  items  placed  in  the  Premises  by  Tenant.    Tenant  shall  fasten  all  files,  bookcases,  and  like 
furnishings to walls in a manner to prevent tipping over in the event of earthquake, tremor, or other earth movements.  Landlord shall not 
be  responsible  for  any  damage  or  liability  for  such  events.    No  machinery,  equipment,  apparatus,  or  other  appliance  shall  be  used  or 
operated in or on the Premises that will in any manner injure, vibrate, or shake all or any part of the Project or be allowed to interfere with 
the  equipment  of  any  other  tenant  within  the  Project  (or  other  property  owned  by  Landlord  or  its  affiliates),  including,  without  limitation, 
interference with transmission and reception of telephone, telecommunications, television, radio, or similar signals.

defined by ADA.  Tenant shall not offer its goods and services to the general public at the Premises.  

5.5.8.The Premises will be used only as a commercial facility and not as a place of public accommodation as 

5.6. Access Rights.  Except as set forth herein, Tenant will have 24 hour-a-day, 7 day-a-week access to the Building 
and the Premises.  Notwithstanding the foregoing, no failure of such access rights will constitute an eviction (constructive or otherwise) or 
a  disturbance  of  Tenant’s  use  and  possession  of  the  Premises  or  relieve  Tenant  from  paying  Rent  or  performing  any  of  its  obligations 
under this Lease; except that Tenant shall be entitled to equitable abatement of its Rent (as defined below) obligations hereunder to the 
extent such lack of access is due to Landlord's negligence or intentional misconduct and continues for a period in excess of 3 business 
days. Landlord will not be liable, under any circumstances, for a loss of or injury to property or for injury to or interference with Tenant’s 
business,  including  loss  of  profits  through,  in  connection  with,  or  incidental  to  a  failure  to  furnish  access  under  this  Paragraph. 
Notwithstanding the foregoing, Landlord agrees to use reasonable efforts to promptly correct any such interruption of access.

5.7. Remedies for Breach.  In the event of any breach of this Paragraph 5 by Tenant or Tenant's Invitees, Landlord, at 
its election and in addition to its other rights and remedies under this Lease, may pay the cost of correcting such breach and Tenant shall 
immediately, upon demand, pay Landlord the cost thereof, plus a supervisory fee in the amount of 10% of such cost.

6. Security Deposit.

6.1. Security Deposit.  Upon Tenant’s execution of this Lease, Tenant shall 

 6

American Assets Trust – Lease Form 1/31/2023

 
 
 
 
 
 
 
 
 
 
 
 
deposit with Landlord good funds in the amount of the Security Deposit (if any) set forth in the Principal Lease Provisions, to secure the 
performance by Tenant of its obligations under this Lease, including without limitation Tenant's obligations (i) to pay Basic Monthly Rent 
and Additional Rent (as defined below), (ii) to repair damages to the Premises and/or the Project caused by Tenant or Tenant’s Invitees, 
(iii) to surrender the Premises in the condition required by Paragraph 23.1, below, and (iv) to remedy any other defaults by Tenant in the 
performance of any of its obligations under this Lease.  If Tenant commits any default under this Lease, Landlord may, at its election, use 
the Security Deposit to cure such default, and to compensate Landlord for all damages actually suffered by Landlord which are directly 
attributable  to  such  default,  including,  without  limitation,  reasonable  attorneys'  fees  and  costs  incurred  by  Landlord.    Upon  demand  by 
Landlord,  Tenant  shall  promptly  pay  to  Landlord  a  sum  equal  to  any  portion  of  the  Security  Deposit  so  used  by  Landlord,  in  order  to 
maintain  the  Security  Deposit  in  the  amount  set  forth  in  the  Principal  Lease  Provisions  above  (subject  to  increase  as  set  forth  below).  
Should  Landlord  choose  to  apply  the  Security  Deposit  against  damages  suffered  by  it,  such  application  shall  not  establish  or  signify  a 
waiver of any other rights or remedies of Landlord hereunder, nor shall such application constitute an accord and satisfaction.  If the Basic 
Monthly Rent shall, from time to time, increase during the Term, then, upon demand by Landlord, Tenant shall deposit with Landlord cash 
in an amount necessary to increase the Security Deposit such that it shall at all times bear the same proportion to the then‑current Basic 
Monthly Rent as the initial Security Deposit bears to the initial Basic Monthly Rent.  Within 45 days following the Expiration Date or earlier 
termination of this Lease, Landlord shall deliver to Tenant, at Tenant's last known address, any portion of the Security Deposit not used by 
Landlord, as provided in this Paragraph.  Landlord may commingle the Security Deposit (and any advance Rent received by Landlord) with 
Landlord's other funds and Landlord shall not pay interest on such Security Deposit to Tenant. Tenant waives the provisions of California 
Civil  Code  Section  1950.7  (or  any  successor  statute),  and  any  similar  principle  of  Laws  with  respect  to  Landlord’s  ability  to  apply  the 
Security Deposit against future rent damages.  Furthermore, upon lawful termination of the Lease as a result of Tenant’s default, Landlord 
shall be entitled to immediately apply the Security Deposit against damages computed under California Civil Code Section 1951.2, without 
the requirement that Tenant first be given notice and an opportunity to cure, and notwithstanding that the damages have not been finally 
adjudicated  by  a  court.    Tenant  may  not  assign  or  encumber  Tenant's  residual  rights  in  the  Security  Deposit  without  the  consent  by 
Landlord.

7. Rent and Rent Adjustments.

7.1.

Initial  Monthly  Rent.    Tenant  shall  pay  to  Landlord  as  minimum  monthly  rent,  without  deduction,  setoff,  prior 
notice, or demand, the Basic Monthly Rent described in the Principal Lease Provisions (subject to adjustment as provided in the attached 
Addendum), in advance, on or before the first day of each calendar month, beginning on the Rent Commencement Date and thereafter 
throughout  the  Term.    If  the  Rent  Commencement  Date  is  other  than  the  first  day  of  a  calendar  month,  then  the  Basic  Monthly  Rent 
payable by Tenant for the second month of the Term following the Rent Commencement Date (acknowledging that the first month’s rent is 
payable  upon  Lease  execution)  shall  be  prorated  on  the  basis  of  the  actual  number  of  days  during  the  Term  occurring  during  the  first 
partial calendar month thereof. 

attached Addendum No. 1 to this Lease.

7.2. Rental Adjustments.  The Basic Monthly Rent shall be increased periodically in accordance with the provisions of

Operating  Expenses  (as  defined  below)  that  are  in  excess  of  the  amount  of  Operating  Expenses  applicable  to  the  Base  Year.    The 
amounts  payable  pursuant  to  this  Paragraph,  together  with  all  other  amounts  of  any  kind  (other  than  Basic  Monthly  Rent)  payable  by 
Tenant to Landlord under the terms of this Lease, constitute additional rent for the Premises and are collectively and individually referred to 
in this Lease as “Additional Rent”.

7.4. General Rental Provisions.  All “Rent”  (which  includes  Basic  Monthly  Rent  and  all  “Additional Rent”  hereunder) 
shall be paid to Landlord at the same address as notices are to be delivered to Landlord pursuant to the Principal Lease Provisions, as 
Landlord may change such address from time to time pursuant to the terms of this Lease.

any  of  Landlord’s  employees  provide  services  for  more  than  one  project  of  Landlord's,  only  the  prorated  portion  of  those  employees’

Landlord, (i) in order to comply with any Laws, change in Laws, or any other rules, regulations or requirements of any governmental or 
quasi-governmental authority having jurisdiction or of the board of fire underwriters or similar insurance body (except to the extent Tenant 
is otherwise obligated, pursuant to this Lease, to undertake such improvements or structural modifications at Tenant’s cost), or (ii) in order

other  tenants’  premises  that  are  directly  paid  for,  or  reimbursed,  by  such  other  tenants.  All  capital  expenditures  shall  be  amortized 
(including interest on the unamortized cost at the rate stated in subparagraph (o) of this Paragraph) over their useful life, as reasonably 
determined  by  Landlord’s  certified  public  accountant.  Operating  Expenses  will  not,  however,  include  any  Excluded  Costs  (as  defined 
below).

8.1.2.Excluded  Costs.    “Excluded  Costs”  means  the  following  expenses,  as  they  relate  to  the  Operating 
Expenses:  (i) depreciation, principal, interest, and fees on mortgages or ground lease payments, except as otherwise expressly provided 
herein,  (ii)  legal  fees  incurred  in  negotiating  and  enforcing  tenant  leases,  or  disputes  with  other  tenants,  its  employees  or  property

a single individual tenant, or costs incurred for the benefit of a single tenant, (vi) costs of any items to the extent Landlord actually receives 
reimbursement therefor from insurance proceeds, under warranties, or from a tenant or other third party (such costs shall be excluded or

reserves  previously  included  in  Operating  Expenses,  (vii)  costs  incurred  due  to  Landlord’s  breach  of  Laws  or  ordinance,  (viii)  repairs

same  are  distinguished  from  the  costs  of  operation  of  the  Building,  (xix)  overhead  and  profit  increment  paid  to  the  Landlord  or  to 
subsidiaries or affiliates of the Landlord for services to the extent the same exceeds the costs of such services rendered by qualified, first-
class unaffiliated third parties on a competitive basis; (xx) costs, including fines or penalties, incurred due to a violation of any law in force 
and effect as of the Lease Commencement Date; (xxi) costs incurred to comply with laws relating to the removal of Hazardous Substances

3.5% of the gross revenue of the Project.

which any portion of the Term falls, through and including the calendar year in which the Term expires.

8.1.3.Expense Year.    “Expense Year”  means  the  Base  Year,  and  each  calendar  year  after  the  Base  Year,  in 

8.1.4.Tenant's  Share.    “Tenant’s  Share”  means  a  fraction,  the  numerator  of  which  is  the  total  aggregate 
Rentable Square Feet in the Premises, and the denominator of 18,788 which is the total aggregate Rentable Square Feet in the Building.  
As of the Lease Commencement Date, the Tenant's Share will be 30.54%.  If either the Premises or the Building are expanded or reduced, 
Tenant’s Share shall be appropriately adjusted.  Tenant’s Share for the Expense Year in which that change occurs shall be determined on 
the basis of the number of days during the Expense Year in which each such Tenant’s Share was in effect.

8.2. Adjustment of Operating Expenses.  Operating Expenses shall be adjusted as follows:

8.2.1.Gross  Up  Adjustment  When  a  Building  is  Less  Than  Fully  Occupied.    If  the  occupancy  of  the  total 
Rentable Square Footage of the completed, partially occupied Building is less than 95%, Landlord shall make an appropriate adjustment to 
the  variable  components  of  the  Operating  Expenses  for  that  Expense  Year,  as  estimated  by  Landlord  in  its  sole  discretion  using  sound 
accounting and management principles, to determine the amount of Operating Expenses that would have been incurred had such building 
been  95%  occupied.    This  amount  shall  be  considered  to  have  been  the  amount  of  Operating  Expenses  for  that  Expense  Year.    For 
purposes  of  this  Paragraph  8.2.  “variable  components”  include  only  those  component  expenses  that  are  affected  by  variations  in 
occupancy levels, such as nightly janitorial service to Tenants’ Premises or water usage.

8.2.2.Adjustment When Landlord Adds Additional Buildings to the Project. If Landlord adds additional buildings 
within the Project following the Base Year, Landlord shall make an appropriate adjustment to the Operating Expenses for the Base Year, as 
reasonably determined by Landlord using sound accounting and management principles, to determine the amount of Operating Expenses 
that would have been incurred for the Base Year if such additional building had been complete and 95% occupied during the Base Year.

8.2.3.Adjustment  When  Landlord  Does  Not  Furnish  a  Service  to  All  Tenants.    If,  during  any  part  of  any 
Expense Year (including the Base Year), Landlord is not furnishing a particular service or work (the cost of which, if furnished by Landlord, 
would be included in Operating Expenses) to a tenant (other than Tenant) that has undertaken to perform such service or work in lieu of 
receiving  it  from  Landlord,  Operating  Expenses  for  that  Expense  Year  shall  be  considered  to  be  increased  by  an  amount  equal  to  the 
additional Operating 

American Assets Trust – Lease Form 1/31/2023

Expenses that Landlord would reasonably have incurred during such period if Landlord had furnished such service or work to that tenant.  
Likewise, if, during any part of any Expense Year (including the Base Year), Landlord begins furnishing a particular service or work (the 
cost  of  which,  if  furnished  by  Landlord,  would  be  included  in  Operating  Expenses)  to  a  tenant  (other  than  Tenant)  that  was  previously 
undertaken by Tenant in lieu of receiving it from Landlord, Operating Expenses for that Expense Year shall be considered to be decreased 
by an amount equal to the reduction in Operating Expenses that would reasonably have occurred during such period now that Landlord is 
furnishing such service or work to that tenant.

8.2.4.Additional  Costs.    If  due  to  a  change  in  the  types  of  costs  being  incurred  by  Landlord  as  Operating 
Expenses (such as, for example, the commencement or cessation of security services—but not a mere change in how a particular cost is 
handled—such as going from an in-house to an outside landscaping service), the Base Year Operating Expenses need to be adjusted to 
eliminate the effect of such change, Landlord shall reasonably adjust the Base Year Operating Expenses and notify Tenant of such change 
in  writing.  Furthermore,  Landlord  shall  have  the  right  to  reasonably  decrease  the  amount  of  the  Base  Year  Operating  Expenses  for 
purposes of calculating Increased Operating Expenses to eliminate the effect of abnormally high costs, or unusual costs, of a particular 
type or types (such as, by way of example, abnormally high energy costs associated with the “energy crisis” of 2001) occurring during the 
Base Year.  There shall be no cap on Operating Expenses.

8.2.5.Common Areas.  Landlord shall elect to partition/separate portions of the Common Areas of the Project 
such that the Operating Expenses (including, but not limited to Tax Expenses and Insurance Expenses) associated with such partitioned 
Common Areas are equitably allocated to particular buildings or parcels within the Project.

8.3.

Tax Expenses.    “Taxes”  means  and  refers  to  all  federal,  state,  county,  or  local  government  or  municipal  taxes, 
fees,  charges,  or  other  impositions  of  every  kind  or  nature,  whether  general,  special,  ordinary,  or  extraordinary.  Taxes  include,  without 
limitation,  taxes,  fees,  and  charges  such  as  real  property  taxes,  general  and  special  assessments  (including,  without  limitation, 
maintenance assessment district assessments, facilities benefit assessments and similar district fees and assessments), transit taxes and 
surcharges, leasehold taxes, school taxes, sewer charges and taxes based on the receipt of rent (including gross receipts or sales taxes 
applicable  to  the  receipt  of  rent,  unless  required  to  be  paid  by  Tenant),  and  personal  property  taxes  imposed  on  Landlord's  fixtures, 
machinery,  equipment,  apparatus,  systems,  appurtenances,  and  other  personal  property  used  in  connection  with  the  Project  or  the 
Building, as the case may be, along with reasonable legal and other professional fees, costs and disbursements incurred in connection 
with proceedings to contest, determine or reduce real property taxes. Notwithstanding the foregoing, the following shall be excluded from 
Taxes: (a) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal, 
state, and local income taxes, and other taxes applied or measured by Landlord’s general or net income (as opposed to rents, receipts, or 
income attributable to operations at the Building), and (b) personal property taxes attributable to property owned or installed by or for other 
tenants of the Project. For all purposes of this Lease, the term “Tax Expenses” shall mean the sum of all Taxes that are paid or incurred by 
Landlord because of or in connection with the ownership, leasing, and/or operation of the Project from time to time. 

Expense Year shall be calculated and paid as follows:

8.4. Calculation and Payment of Operating Expenses.  Tenant’s Share of the increased Operating Expenses for any 

8.4.1.Calculation of Excess.  If Operating Expenses for any Expense Year (other than the Base Year) ending or 
beginning within the Term exceeds the amount of Operating Expenses applicable to the Base Year, Tenant shall pay as Additional Rent to 
Landlord an amount equal to Tenant’s Share of that excess, in the manner stated below.

8.4.2.Statement/Payment  of  Operating  Expenses.    Tenant  shall  pay  to  Landlord,  on  the  first  day  of  each 
calendar month during the Term, commencing January 1, 2025, as Additional Rent, without notice, demand, offset, or deduction (except as 
provided below), an amount (“Tenant's Monthly Payment”) equal to one-twelfth of Tenant's Share of the amount by which the Operating 
Expenses  for  each  Expense  Year  following  the  Base  Year  exceed  the  Base  Year  Operating  Expenses  (such  excess  being  referred  to 
herein as the “Increased  Operating  Expenses”),  as  estimated  (and  subsequently  reconciled)  by  Landlord  in  the  most  recently  delivered 
Estimated  Statement  (as  defined  below).    Landlord  intends  to  deliver  to  Tenant,  prior  to  the  commencement  of  each  Expense  Year 
following  the  Base  Year  during  the  Term,  a  written  statement  (“Estimated Statement”)  setting  forth  Landlord's  estimate  of  the  Operating 
Expenses  and  Increased  Operating  Expenses  allocable  to  the  ensuing  Expense  Year,  and  Tenant's  Share  of  such  Increased  Operating 
Expenses.    Landlord  may,  at  its  option,  during  any  Expense  Year,  deliver  to  Tenant  a  revised  Estimated  Statement,  revising  Landlord's 
estimate of the Operating

Expenses and Increased Operating Expenses, in accordance with Landlord's most current estimate.  Within approximately 90 days after 
the end of each Expense Year during the Term, Landlord intends to deliver to Tenant a written statement (“Actual Statement”) setting forth 
the actual Operating Expenses allocable to the preceding Expense Year.  Tenant's failure to object to Landlord regarding the contents of 
an Actual Statement, in writing, within 90 days after delivery to Tenant of such Actual Statement, shall constitute Tenant's absolute and 
final  acceptance  and  approval  of  the  Actual  Statement.    If  the  sum  of  Tenant's  Monthly  Payments  actually  paid  by  Tenant  during  any 
Expense Year exceeds Tenant's Share of the actual Increased Operating Expenses allocable to such Expense Year, then such excess will 
be  credited  against  future  Tenant's  Monthly  Payments,  unless  such  Expense  Year  was  the  Expense  Year  during  which  the  Lease 
Expiration Date occurs (the “Last Calendar Year”), in which event either (i) such excess shall be credited against any monetary default of 
Tenant under this Lease, or (ii) if Tenant is not in default under this Lease, then Landlord shall (within the time frame for returning Tenant's
Security Deposit) pay to Tenant such excess.  If the sum of Tenant's Monthly Payments actually paid by Tenant during any Expense Year 
is less than Tenant's Share of the actual Increased Operating Expenses allocable to such Expense Year, then Tenant shall, within 30 days 
after  delivery  of  the  Actual  Statement,  pay  to  Landlord  the  amount  of  such  deficiency.    Landlord's  delay  in  delivering  any  Estimated 
Statement or Actual Statement will not release Tenant from its obligation to pay any Tenant's Monthly Payment or any such excess upon
receipt  of  the  Estimated  Statement  or  the  Actual  Statement,  as  the  case  may  be.    The  references  in  this  Paragraph  8.4  to  the  actual 
Increased  Operating  Expenses  allocable  to  an  Expense  Year,  shall  include,  if  such  Expense  Year  is  the  Last  Calendar  Year,  the  actual 
Increased  Operating  Expenses  allocable  to  the  portion  of  such  year  prior  to  the  Lease  Expiration  Date,  calculated  on  a  pro  rata  basis, 
without regard to the date of a particular expenditure. The provisions of this Paragraph 8.4 shall survive the termination of this Lease, and 
even  though  the  Term  has  expired  and  Tenant  has  vacated  the  Premises,  when  the  final  determination  is  made  of  Tenant’s  Share  of 
Operating  Expenses  for  the  year  in  which  this  Lease  terminates,  Tenant  shall  immediately  pay  any  increase  due  over  the  estimated 
expenses paid by Tenant pursuant hereto and conversely any overpayment made in Tenant's estimated payments shall be immediately 
rebated by Landlord to Tenant.

8.5.

Landlord's Books and Records.  If Tenant disputes (in a writing delivered to Landlord setting forth with specificity 
the basis for such dispute and the portions of such Actual Statement which Tenant disputes) the amount of Additional Rent stated in an 
Actual Statement within 90 days after delivery thereof to Tenant, Tenant may, upon at least 5 business days’ notice to Landlord, request an 
opportunity to inspect and audit Landlord’s records and supporting documentation regarding such Actual Statement (but not regarding any 
other Actual Statement). Such inspection and audit must be conducted by an independent certified public accountant within 180 days after 
the date Tenant received the Actual Statement, shall be at Tenant’s sole cost and expense (except as provided below), and Landlord shall, 
at  its  election,  either  provide  copies  of  such  records  and  supporting  documentation  to  Tenant  or  make  such  records  and  supporting 
documentation relating to the matter in dispute available to Tenant for its inspection at Landlord’s business office during normal business 
hours. If Tenant fails to dispute (in writing, as provided above) the amount of Additional Rent stated in an Actual Statement within 90 days 
after Tenant’s receipt thereof, or if Tenant's inspection and audit fails to disclose a discrepancy in such Actual Statement within 180 days 
after Tenant's receipt of the Actual Statement in question, then the Actual Statement will be deemed accurate and binding on Tenant and 
Tenant will be estopped from raising or pursuing any claim or defense to the contrary. If it is determined as a result of Tenant's timely audit 
of  Landlord's  records  (and  Landlord's  certified  public  accountant's  concurrence  therewith)  that  Tenant  was  overcharged  relative  to  the 
Operating Expenses, such overcharge shall entitle Tenant to a credit against its next payment of Operating Expenses in the amount of the 
overcharge plus, in the case of an overcharge exceeding 3% of the Operating Expenses, the reasonable third party costs of such audit 
(and  if  such  credit  occurs  following  the  expiration  of  the  Term,  Landlord  shall  promptly  pay  the  amount  of  such  credit  to  Tenant).  If  it  is 
determined as a result of Tenant's timely audit of Landlord's records (and Landlord's certified public accountant's concurrence therewith), 
or  otherwise,  that  Tenant  was  undercharged  relative  to  the  Operating  Expenses,  Tenant  shall,  within  30  days  after  written  demand,  pay 
such  undercharge  to  Landlord.    Landlord  shall  be  entitled  to  a  copy  of  any  such  audit.    For  avoidance  of  doubt,  Landlord  shall  not  be 
required to provide or make available to Tenant any of Landlord’s records (i) that would result in the disclosure of confidential information 
pertaining to any other tenant in the Project or (ii) under any circumstances, except as may be required by Laws, unless Tenant exercises 
its inspection and audit rights pursuant to this Paragraph 8.5. Notwithstanding anything to the contrary in this Paragraph 8.5, Tenant's right 
to inspect and audit Landlord's records and to otherwise dispute any Actual Statement are subject to the following conditions:

8.5.1.No audit may be conducted during the months of December or April, and Tenant's auditor must make an 
advance  appointment  with  Landlord's  audit  supervisor  at  a  mutually  acceptable  time  (which  Landlord  will  use  reasonable  efforts  to 
schedule within 60 days of Tenant's request).

billed and must not be in default of any other provisions of this Lease.

8.5.2.Before conducting an audit, Tenant must pay the full amount of Tenant's Share of Operating Expenses 

8.5.3.Tenant may review only those records of Landlord specifically related to the specific Operating Expenses 
which  Tenant  has  disputed.  Tenant  may  not  review  any  other  records  or  any  other  leases  or  agreements,  or  Landlord's  tax  returns  or 
financial statements.

auditing commercial office property records, subject to Landlord's reasonable prior approval.

8.5.4.In  conducting  an  audit,  Tenant  must  utilize  an  independent  certified  public  accountant  experienced  in 

data.

8.5.5.Upon  receipt  thereof,  Tenant  will  deliver  to  Landlord  a  copy  of  the  audit  report  and  all  accompanying 

8.5.6.Tenant will keep confidential all agreements involving the rights provided in this Paragraph 8.5 and the 
results of any audits conducted hereunder. Notwithstanding the foregoing, Tenant will be permitted to furnish the foregoing information to 
its attorneys, accountants, and auditors to the extent necessary to perform their respective services for Tenant.

8.5.7.An audit may be conducted only once with respect to any Actual Statement, even if the audit conducted 

does not address every Operating Expense set forth in the Actual Statement.

8.5.8.Tenant may not use an auditor under this Paragraph 8.5 who is paid on a contingency basis, or whose 
pay  is  based,  in  whole  or  in  part,  on  the  amount  of  recovery  or  any  reduction  of  Tenant’s  Share  of  Additional  Rent  resulting  from  such 
audit.

9. Utilities and Services.

Tenant’s Utility Costs.  Except as provided below, Tenant shall pay when due all bills for gas, electricity, and other 
utilities used at the Premises on and after the Rent Commencement Date and through and including the date of expiration of this Lease, 
that are separately metered and assessed for utility services servicing the Premises during the Term.

Landlord shall provide HVAC when necessary for normal comfort for normal office use in the Premises during Building Standard Operating 
Hours.

9.2.2.Landlord shall provide adequate electrical wiring and facilities sufficient to provide electrical current to the 
Premises  for  Project-standard  ordinary  and  customary  office  uses  and  excluding  electrical  power  required  for  electric  data  processing 
equipment,  computer  rooms,  special  lighting  in  excess  of  Building  standard  lighting,  or  any  other  item  of  electrical  equipment  which 
(individually) consumes more than 1.8 kilowatts at rated capacity in which requires a voltage other than 120 volts single phase. In addition 
to  the  foregoing,  Landlord  shall  replace  lamps,  starters,  and  ballasts  for  Project-standard  lighting  fixtures  within  the  Premises  upon 
Tenant’s request; the expense of which will be an Operating Expense. Tenant shall replace lamps, starters, and ballasts for non-Project-
standard lighting fixtures within the Premises at Tenant’s sole expense.  Landlord shall also provide electrical service in connection with 
Common Area needs, such as lighting.

9.2.3.Landlord shall provide adequate electricity and other customary utility services to the Premises.  Landlord 
shall also provide hot and cold city water from the regular Building outlets for drinking, lavatory and toilet purposes in the Building Common 
Areas and at points of supply within the Premises.

9.2.4.Landlord shall provide 5 day per week ordinary and customary, basic janitorial services in and about the 
Premises in a manner consistent with other comparable buildings in the vicinity of the Building.  Landlord shall not be required to provide 
janitorial services to above-Project-standard improvements installed in the Premises including but not limited to metallic trim, wood floor 
covering, glass panels, interior windows, kitchen/dining areas, executive washrooms, or shower facilities.  Any janitorial services required 
by  Tenant  and  provided  by  Landlord  in  excess  of  such  ordinary  and  customary,  basic  janitorial  services  shall  be  separately  paid  for  by 
Tenant, as Additional Rent, within 10 days of written demand.

Building  Standard  Operating  Hours,  shall  have  one  elevator  available  at  all  other  times,  including  on  the  Holidays,  and  shall  provide 
nonexclusive, non-attended automatic passenger escalator service during Building Standard Operating Hours only.

9.2.6.Landlord shall provide nonexclusive freight elevator service subject to scheduling by Landlord.

Tenant shall cooperate fully with Landlord at all times and abide by all regulations and requirements that Landlord may reasonably 

prescribe for the proper functioning and protection of the HVAC, electrical, mechanical, and plumbing systems.

9.3. Over-Standard Tenant Use.  Tenant shall not exceed the rated capacity of the Building’s electrical and other utility 
systems, which systems will be consistent in capacity with other first class office buildings built at or about the same time as the Building.  
In the event of any damage to any of the Project’s systems caused by Tenant’s use thereof in excess of ordinary and customary usage for 
a  professional  office.    Tenant  shall  be  responsible  for  all  costs  and  expenses  incurred  by  Landlord  as  a  result  of  such  over-use.    In 
addition, if Tenant requires any utilities or services described in this Paragraph 9, which are to be provided by Landlord, in excess of the 
standard levels being provided by Landlord, or during hours other than Building Standard Operating Hours, Landlord shall have the right to 
impose reasonable restrictions on such usage and/or commercially reasonable charges therefor.  The initial charge to Tenant for heating 
and  air  conditioning  during  hours  other  than  Building  Standard  Operating  Hours  will  be  $55.00  per  hour  (or  portion  thereof),  subject  to 
increase over the Term, including the Extension Term, if any.  Such charges are Additional Rent relative to the provision of such services 
and are not an offset to any Operating Expenses.

9.4. Conduit and Wiring.  Installation of all types of conduit and wiring exclusively serving the Premises (other than as 
part of Landlord's Work), including but not limited to Tenant's Work, is subject to the requirements of Paragraph 22, below, Exhibit “C”, and
the Landlord’s reasonable approval of the location, manner of installation, and qualifications of the installing contractor.  All such conduit 
and wiring will, at Landlord's option, become Landlord's property upon the expiration of the Term.  Upon expiration of the Term, Landlord 
may elect to require Tenant to remove such conduit and wiring at Tenant's expense and, with respect to such conduit and wiring, return the 
Premises  and  the  Common  Areas  to  substantially  their  pre-existing  condition.    If  Landlord  constructs  new  or  additional  utility  facilities, 
including  without  limitation  wiring,  plumbing,  conduits,  and/or  mains,  resulting  from  Tenant's  changed  or  increased  utility  requirements, 
Tenant shall on demand promptly pay (or advance) to Landlord the cost of such items as Additional Rent.  

9.5. Utilities  Generally.    Tenant  agrees  that,  except  as  specifically  provided  below,  Landlord  will  not  be  liable  for 
damages, by abatement of Rent or otherwise, for failure to furnish or for delay in furnishing any utility or related service (including, without 
limitation,  telephone  and  telecommunication  services)  or  for  diminution  in  the  quality  or  quantity  of  any  utility  or  related  service.    Such 
failure,  delay,  or  diminution  will  not  constitute  an  eviction  or  a  disturbance  of  Tenant’s  use  and  possession  of  the  Premises  or  relieve 
Tenant from paying Rent or performing any of its obligations under this Lease, except that Tenant will be entitled to an equitable abatement 
of Rent for the period of such failure, delay, or diminution to the extent such the following are satisfied; (i) failure, delay, or diminution is 
directly  attributable  to  Landlord’s  gross  negligence  or  intentional  misconduct,  (ii)  such  failure,  delay  or  diminution  prevents  Tenant  from 
using, and Tenant does not use, the Premises or the affected portion thereof for the conduct of Tenant's business operations therein, (iii) 
Tenant was using the Premises or such affected portion for the conduct of Tenant's business operations immediately prior to the failure, 
delay or diminution, (iv) such failure, delay, or diminution continues for more than 2 consecutive business days (or 10 business days in any 
12-month period) after delivery of written notice of such failure, delay, or diminution from Tenant to Landlord, (v) the restoration of such 
utility or related service is reasonably within the control of Landlord, and (vi) Tenant’s losses arising from such failure, delay, or diminution 
are not covered by any insurance required to be maintained by Tenant under this Lease or otherwise maintained by Tenant. Landlord and 
Tenant acknowledge that such abatement of Basic Monthly Rent and Additional Rent constitutes reasonable liquidated damages for any 
and  all  of  Tenant's  monetary  loss  caused  by  the  interruption  of  such  utility  and/or  service,  given  that  Tenant's  actual  damages  are 
extremely difficult or impossible to calculate.  Except as otherwise expressly provided in this Lease, in no event shall such failure, delay, or 
diminution  in  the  quality  or  quantity  of  any  utility  or  service  relieve  Tenant  of  any  of  its  obligations  under  the  Lease,  or  constitute 
constructive  eviction  or  entitle  Tenant  to  consequential  damages.  Landlord  will  not  be  liable,  under  any  circumstances,  for  a  loss  of  or 
injury to property or for injury to or interference with Tenant’s business, including loss of profits through, in connection with, or

incidental to a failure to furnish any of the utilities or services under this Paragraph.  Notwithstanding the foregoing, Landlord agrees to use 
reasonable efforts to promptly correct any such interruption of utilities or services (unless such interruption of service was caused by the 
negligence of Tenant, or anyone acting by, through or under Tenant). Tenant hereby waives the provisions of California Civil Code Section 
1932(1)  or  any  other  applicable  existing  or  future  Laws  permitting  the  termination  of  this  Lease  due  to  the  interruption  or  failure  of  or 
inability to provide any services required to be provided by Landlord hereunder.  If any governmental authority having jurisdiction over the 
Project  imposes  mandatory  controls,  or  suggests  voluntary  guidelines  applicable  to  the  Project,  relating  to  the  use  or  conservation  of 
water, gas, electricity, power, or the reduction of automobile emissions, Landlord, at its sole discretion, may comply with such mandatory 
controls  or  voluntary  guidelines  and,  accordingly,  require  Tenant  to  so  comply.    Landlord  shall  not  be  liable  for  damages  to  persons  or 
property for any such reduction, nor shall such reduction in any way be construed as a partial eviction of Tenant, cause an abatement of 
Rent, or operate to release Tenant from any of Tenant's obligations under this Lease, except as specifically provided in this Paragraph 9.5.  
By  executing  this  Lease,  Tenant  hereby  authorizes  Landlord  to  obtain  information  regarding  Tenant’s  utility  and  energy  usage  at  the 
Premises directly from the applicable utility providers or any governmental agency and Tenant shall execute, within 5 days of Landlord’s 
request, any additional documentation required by any applicable utility provider evidencing such authorization.  Further, within 15 days of 
Landlord’s request, Tenant shall provide to Landlord all requested information regarding Tenant’s utility and energy usage at the Premises, 
which information may include copies of Tenant’s utilities bills.

10.Maintenance.

10.1. Tenant's Duties.  Tenant shall at its sole cost maintain, repair, replace, and repaint, all in first class condition, the 
interior  of  the  Premises,  all  building  systems  exclusively  serving  the  Premises  and  located  within  the  Premises  or  the  walls  of  the 
Premises,  and  any  damage  to  the  Premises  or  the  Project  resulting  from  the  acts  or  omissions  of  Tenant  or  any  of  Tenant's  Invitees. 
Tenant  shall  maintain  all  communications  conduit,  equipment,  and  wiring  serving  the  Premises,  whether  in  the  Premises  or  not  (and 
specifically  including  all  of  Tenant’s  Work  and  all  wiring,  equipment,  and  conduit  located  on  the  roof  of  the  Building),  regardless  of  the 
ownership of said conduit or wiring, subject to Landlord’s reasonable approval of Tenant’s maintenance/repair contractor and manner of 
maintenance/repair (but excluding those portions of the Premises which are the express responsibility of Landlord pursuant to Paragraph 
10.2 below).  Notwithstanding anything to the contrary contained herein, Tenant shall pay any and all maintenance and recurring costs for 
supplemental HVAC units exclusively serving the Premises, or any portion thereof, upon presentation of invoice from Landlord.  If Tenant 
fails to maintain, repair, replace, or repaint any portion of the Premises or the Project as provided above then following 10 days’ written 
notice thereof to Tenant, Landlord may, at its election, maintain, repair, replace, or repaint any such portion of the Premises or the Project 
and Tenant shall promptly reimburse Landlord, as Additional Rent, for Landlord's actual cost thereof, plus a supervisory fee in the amount 
of 10% of Landlord’s actual cost.  Notwithstanding the foregoing, if following Tenant’s payment (or performance) of its obligations under 
this Paragraph, Landlord receives payment from an insurer for such work, Tenant will be entitled to receive such proceeds (after Landlord 
has  first  been  fully  reimbursed  for  its  costs  and  expenses  relative  thereto  including  Landlord’s  costs  and  expenses  in  obtaining  such 
proceeds) to the extent Tenant previously paid or incurred third party costs relative thereto.

10.2. Landlord's Duties.  Landlord shall, as part of the Operating Expenses (subject to Section 8.1),  maintain, repair, 
replace,  and  repaint,  all  in  good  order  and  condition,  consistent  with  other  first-class  office  buildings  in  the  vicinity  of  the  Building,  the 
Common  Areas  and  all  portions  of  the  interior  and  exterior  of  the  Building  and  any  other  buildings  in  the  Project  (including,  without 
limitation, all electrical, mechanical, plumbing, fire/life safety, and other building systems), except to the extent of Tenant's obligations as 
set forth in Paragraph 10.1, above.  Landlord's failure to perform its obligations set forth above will not release Tenant of its obligations 
under this Lease, including without limitation Tenant's obligation to pay Rent.  Tenant waives the provisions of California Civil Code Section 
1942 (or any successor statute), and any similar principle of Laws with respect to Landlord's obligations for tenantability of the Premises 
and  Tenant's  right  to  make  repairs  and  deduct  the  expense  of  such  repairs  from  rent.    If  Landlord  fails  to  perform  any  of  its  repair  and 
maintenance obligations under this Paragraph 10.2 and such failure materially and adversely impairs Tenant’s ability to use and occupy 
the  Premises  for  the  Permitted  Use,  Tenant  will  have  the  right,  to  perform  such  repairs  and/or  maintenance  to  the  extent  necessary  to 
enable Tenant to resume its use and occupancy of the Premises.   Notwithstanding the foregoing, prior to exercising such right, Tenant 
must, except as provided below in connection with an emergency, have given Landlord at least 30 days’ prior written notice of the nature of 
the  problem  and  Tenant’s  intention  to  exercise  its  rights  under  this  Paragraph  if  such  matter  is  not  resolved  within  such  30-day  period; 
provided, however, if the nature of the matter giving rise to such repair or maintenance obligation will reasonably require more than 30 

American Assets Trust – Lease Form 1/31/2023

 14

 
 
 
 
 
days to remedy and Landlord is proceeding with due diligence to remedy such matter, then such 30 day period will be extended for such 
additional time as may be necessary for Landlord to complete such repairs or maintenance.  Notwithstanding the preceding sentence, in 
the case of an emergency which poses an imminent threat of death, injury, or severe damage to persons or property, the required notice 
from  Tenant  may  be  provided  orally  rather  than  in  writing  and  for  such  shorter  period  of  time  (i.e.,  less  than  30  days)  as  Tenant,  in  the 
exercise  of  its  reasonable  judgment  deems  appropriate  under  the  exigent  circumstances  (however,  at  a  minimum,  Tenant  shall  at  least 
contact Landlord telephonically prior to commencing such work so that Landlord may, at its election, make arrangements to handle such 
emergency itself).   If Landlord fails to fulfill its repair and maintenance obligations under this Paragraph, and as a result thereof Tenant 
exercises the foregoing right to correct such matter, then Landlord shall reimburse Tenant for the reasonable third-party costs incurred by 
Tenant to complete such repairs and/or maintenance within 30 days after receipt of Tenant’s written demand therefor, together with copies
of the paid invoices evidencing the costs so incurred.   Any such repairs or maintenance performed by Tenant, as permitted herein, must 
be performed in a good and workmanlike manner by licensed contractors.  Under no circumstances may Tenant offset any amount it is 
owed by Landlord pursuant to this Paragraph (or otherwise) against any Rent obligation under this Lease.

11. Parking.

11.1. General Parking Rights.  Subject to the remaining provisions of this Paragraph 11, Landlord grants to Tenant (for 
the benefit of Tenant and Tenant’s Invitees) the right to the non-exclusive use of the unreserved parking area within the boundaries of and 
serving the Project (the “Parking Area”).  Tenant's use of the Parking Area shall be subject to such rules as Landlord may, in its reasonable 
and non-discriminatory discretion, adopt from time to time with respect to the Parking Area, including without limitation (i) rules providing 
for  the  payment  of  charges  or  fees  by  users  of  the  Parking  Area  subject  to  the  term  and  conditions  set  forth  in  Paragraph  11.2,  below, 
specifically including the final sentence therein, and in such event the charges or fees shall be deemed Additional Rent, (ii) rules limiting 
tenants of the Project (including, without limitation, Tenant) to the use of, or excluding the use of, certain parking spaces or certain portions 
of  the  Parking  Area,  in  order  to  maintain  the  availability  of  accessible  parking  spaces  for  clients,  guests,  and  invitees  of  tenants  of  the 
Project,  and (iii) rules limiting tenants of the Project (including without limitation Tenant), and their employees, to the use of a restricted 
number of parking spaces or a restricted area. If Tenant, or any of Tenant's employees, fails to comply with any such rules or requirement 
(such as, by way of example, parking in areas designated as visitor parking only), then Landlord will have the right to either have such
vehicles  towed  from  the  Project  at  Tenant's  expense,  or  to  charge  Tenant  $100.00  per  day  per  car  for  any  cars  which  are  parked  in 
violation of such requirements. Furthermore, Landlord shall have the right to immobilize such improperly parked vehicles by use of a "boot" 
or other device.   Tenant shall not assign or sublet such parking privileges separate and apart from the other rights of Tenant under this 
Lease.

11.2. Parking Ratios.  As of the Rent Commencement Date (and subject to temporary interruptions in connection with 
Landlord’s continued development of the Project, as provided below), the parking ratio within the Project applicable to Tenant will be four 
(4) spaces per 1,000 Usable Square Feet (“USF”) of space within the Premises.  The foregoing (4:1,000 USF) parking ratio includes all 
spaces within the Project, including covered, uncovered, reserved, unreserved, handicap, and visitor parking spaces.  Of the total spaces 
described above, a maximum of four (4) of said total spaces may be reserved in the parking garage by Tenant at the rate of $100.00 per 
space per month, subject to future escalation by Landlord provided, however, that in no event shall such escalation be more than three 
percent (3%) during any consecutive 12 month period.   All unreserved parking shall be provided on a free and unassigned basis during 
the Initial Lease Term (i.e., first come, first served).

12.Signs.

12.1. General Signage Conditions.  Landlord may at any time change the name of either or both of the Building and/or 
the  Project  and  install,  affix,  and  maintain  all  signs  on  the  exterior  and  interior  of  the  Building  and  other  buildings  within  the  Project  as 
Landlord  may,  in  Landlord’s  sole  discretion,  desire.    Tenant  shall  not  have  or  acquire  any  property  right  or  interest  in  the  name  of  the 
Building or the Project.  Subject to Tenant’s signage rights under Paragraph 12.2. below.  Tenant may not place, construct, or maintain any 
sign, advertisement, awning, banner, or other exterior decoration (collectively, “Sign”) inside or outside the Premises which is visible from 
the exterior of the Premises, or on the Building or any other portion of the Project, without Landlord's prior written consent.  Any sign that 
Tenant is permitted by Landlord to place, construct, or maintain in the Premises or on the Building or the Project (including pursuant to 
Paragraph 12.2. below) must comply with Landlord's sign criteria applicable to the Project, including, without limitation, criteria relating to 
size, color, shape, graphics, and location 

American Assets Trust – Lease Form 1/31/2023

 15

 
 
 
 
 
 
 
(collectively, the “Sign Criteria”), and shall comply with all applicable Laws, ordinances, CC&R’s (or similar recorded instruments), rules, or 
regulations, and Tenant shall obtain any approvals required by such Laws, ordinances, CC&R’s (or similar recorded instruments), rules, 
and regulations.  Landlord makes no representation or warranty with respect to Tenant's ability to obtain any such approval.  Tenant shall, 
at Tenant's sole cost and expense, make any changes to any sign, whether in the Premises or on the Building, as required by any new or 
revised applicable Laws, ordinances, rules, or regulations or any changes in the Project Sign Criteria.  Tenant shall, additionally, maintain, 
repair, and replace all of Tenant’s signs (including, specifically, those installed pursuant to Paragraph 12.2. below) in first class condition.  
Nothing  contained  in  this  Paragraph  12  limits  Landlord’s  right  to  grant  signage  rights  to  other  tenants  of  the  Building,  or  to  affect  the 
signage rights of any tenant of the Building.

Tenant is hereby granted the following signage rights in/on the Building and at the Project.

12.2. Tenant's  Individual  Signage  Rights.    Subject  to  compliance  with  the  requirements  of  Paragraph  12.1,  above, 

12.2.1.Directory/Suite  Signage.    The  Building  will  be  provided,  at  Landlord’s  expense,  with  both  a  Project-
standard lobby directory sign and suite signage. Tenant shall be entitled to be listed on such signs, subject to prior approval of the Tenant’s 
graphics by Landlord, if applicable.

12.2.2.Building Signage.  In addition to the foregoing, and subject to all of the terms, provisions, and conditions 
relating to signage set forth in Paragraph 12.1, above, Landlord hereby grants Tenant the non-exclusive right to install one (1) building top 
sign  located  on  the  east  facing  wall  of  the  Building  (facing  El  Camino  Real)  (the  “Exterior  Building  Sign”).    Such  signage  rights  shall 
continue throughout any period of time during the Lease Term that Tenant is occupying all of the Premises and operating in accordance 
with the Permitted Use definition set forth in the Principal Lease Provisions. The Exterior Building Signage shall be fabricated and installed 
at Tenant's sole expense and Tenant shall be responsible for and pay the cost of maintaining, repairing, and removing the Exterior Building 
Sign.  The  Exterior  Building  Sign  shall  be  professionally  fabricated  in  strict  accordance  with  sign  criteria  established  by  Landlord  for  the 
Project, as may be amended from time to time, as well as any local, city, state or federal requirements.  The location, dimensions, and 
design  of  the  Exterior  Building  Sign  shall  be  subject  to  Landlord’s  prior  approval  (which  may  be  withheld  in  Landlord’s  reasonable 
discretion) and must comply with the City of San Diego Comprehensive Sign Program approved for Torrey Reserve and be approved and 
permitted by the City of San Diego, and any other applicable governmental authority (all costs of approvals, permits, or any other charges 
for such requirements shall be at Tenant’s sole expense).    If Tenant or a Permitted Transferee ceases to occupy and operate within at 
least 75% of the Premises in accordance with the Permitted Use set forth in the Principal Lease Provisions, excluding temporary closures 
for  repair,  remodeling  or  restoration  work,  Tenant  shall,  at  its  sole  expense  and  within  fifteen  (15)  business  days  of  Landlord’s  written 
request, remove the Exterior Building Sign and repair all damage caused by the Exterior Building Sign or its installation, maintenance, or 
removal.  If Tenant fails to maintain the Exterior Building Sign in first class condition and repair, or if Tenant fails to remove the Exterior 
Building Sign as may be required by this Paragraph 12.2 or upon expiration or earlier termination of this Lease and repair any damage 
caused by the former presence of the signage or its removal (including, but not limited to, patching/restoring the affected area, if required 
by Landlord), Landlord may do so at Tenant’s expense.  All sums reasonably disbursed, expended, or incurred by Landlord in connection 
with such removal and repair, shall be reimbursed by Tenant to Landlord, upon Tenant’s receipt of Landlord’s invoice, plus a supervisory 
fee of ten percent of such cost payable to Landlord.  Additionally, all reasonable actual costs and expenses incurred by Landlord relative to 
the maintenance, repair, illumination, and operation of Tenant’s Exterior Building Sign shall constitute Additional Rent under this Lease and 
Tenant shall reimburse Landlord for all such costs immediately upon written request.

12.2.3.Exterior Monument Signage.  Upon written notice to Landlord from Tenant, at any time during the first 
year of the Term, Landlord shall, at Tenant’s sole expense as Additional Rent, install a sign strip on the monument in front of the Building, 
subject to the following requirements: (i) Tenant must obtain Landlord’s and any applicable governmental entity's prior written approval for 
such signs (including all required permits); and (ii) all signs must be in keeping with the quality, design, and style of the Building and the 
rules and regulations and design criteria imposed by Landlord with respect to signage.

13.Rules, Regulations, and Covenants.  Tenant shall faithfully observe and strictly comply with (and shall cause Tenant's Invitees 
to observe and comply with) any rules and regulations which Landlord may from time to time adopt for the Project that do not materially 
increase  Tenant's  obligations  or  materially  decrease  Tenant's  rights  under  the  Lease  (a  copy  of  such  rules  and  regulations  shall  be 
provided to Tenant), as well as any recorded easement 

American Assets Trust – Lease Form 1/31/2023

 16

 
 
 
 
 
 
 
agreements,  maintenance  agreements,  CC&R’s  or  like  instruments  affecting  the  Building  and/or  the  Project,  whether  now  existing  or 
hereafter adopted or amended from time to time (all of the foregoing, collectively, “Rules”).  Landlord has no duty or obligation to enforce 
any  Rule  against  any  other  tenant,  and  Landlord  will  not  be  liable  to  Tenant  for  violation  of  any  Rule  by  any  other  tenant,  or  any  other 
tenant's  agents,  employees,  officers,  independent  contractors,  customers,  invitees,  visitors,  guests  or  licensees.    Tenant  acknowledges 
that Landlord reserves the right, from time to time, to enter into leases or other agreements by which Landlord agrees to restrict the use of 
all or any portion of the Project (including the Premises) from certain uses.  All such leases and other agreements, whether now existing or 
entered  into  in  the  future,  shall  be  binding  upon  Tenant  and  in  no  event  shall  Tenant  utilize  the  Premises  for  any  use  so  prohibited; 
provided, however, no such restriction may prevent Tenant from using the Premises for the Permitted Use.

14.Early Access/Insurance.    If  prior  to  the  Rent  Commencement  Date  Tenant    desires  to  make  any  Alterations  (as  defined  in 
Paragraph 22 below) to the Premises (as approved by Landlord in the attached Exhibit “C”), perform any of the Tenant's Work, or install 
any of Tenant’s personal property, then in addition to complying with the provisions of attached Exhibit “C”, (i) Tenant shall, at Tenant's sole 
cost  and  expense,  prior  to  first  entering  onto  the  Project,  obtain  and  thereafter  at  all  times  maintain  (or,  with  respect  to  Builder’s  Risk 
insurance, cause its contactor to obtain and thereafter at all times maintain) (a) ”Builder's Risk” or “Course of Construction” insurance with 
respect to any actual construction work, and (b) all of the insurance required to be maintained by Tenant during the Term, and (ii) and all 
obligations of Tenant under the provisions of this Lease other than those relating to the obligation to pay Rent, shall be operative.  Without 
limiting the foregoing, any work pursuant to this Paragraph shall be subject to all of the provisions of Paragraph 22, below.  Subject to the 
foregoing, Landlord shall provide such early access no later than ten (10) business days prior to the Lease Commencement Date.

15.Tenant’s  Liability  Insurance.    Tenant  shall  maintain,  at  Tenant's  sole  cost  and  expense,  Commercial  General  Liability 
Insurance  covering  the  insured  against  (i)  any  and  all  Claims  (as  defined  below)  of  bodily  injury,  personal  injury  and  property  damage 
(including loss of use thereof) arising out of or connection with Tenant's use, occupancy and operations within the Premises and Building, 
and (ii) all contractual liabilities under this Lease, including, without limitation, indemnity provisions contained herein, for limits of liability of 
$3,000,000 per occurrence and $4,000,000 annual aggregate and may be met with primary and excess liability policy.

16.Tenant’s Property Damage Insurance.  Tenant shall maintain, at Tenant’s sole cost and expense, Physical Damage Insurance 
covering (i) all office furniture, business and trade fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise 
and all other items of Tenant's property on the Premises installed by, for, or at the expense of Tenant, (ii) all Tenant improvements (installed 
and/or constructed per Exhibit “C” attached hereto), and any other improvements which exist in the Premises as of the Commencement 
Date  (excluding  the  base  building  structure  and  building  systems),  and  (iii)  all  other  improvements,  Alterations,  Personal  Property  and 
additions to the Premises.  Such insurance shall be written on an "all risks" of physical loss or damage basis, for the full replacement cost 
value, new without deduction for depreciation of the covered items and shall include coverage for damage or other loss caused by fire or 
other peril including, but not limited to, terrorism, vandalism and malicious mischief, theft, water damage of any type, including sprinkler 
leakage, bursting or stoppage of pipes, coverage with respect to increased costs due to building ordinances, demolition coverage, boiler 
and machinery insurance and explosion. Such “full replacement cost value” shall be determined by the insurance company issuing such 
policy  at  the  time  the  policy  is  initially  obtained.    Not  more  frequently  than  once  every  two  years,  either  Landlord  or  Tenant  may,  at  its 
election, notify the other that it elects to have the replacement cost value redetermined by an insurance company.  Such redetermination 
shall be made promptly and in accordance with the rules and practices of the Board of Fire Underwriters, or a like board recognized and 
generally accepted by the insurance company, and Landlord and Tenant shall be promptly notified of the results by the company.  Such 
policy shall be promptly adjusted according to such redetermination.

17.Tenant’s  Additional  Insurance.    In  addition  to  the  foregoing  coverages,  Tenant  shall  maintain,  at  Tenant’s  sole  cost  and 

expense:

located;

by disease – each employee and $1,000,000 bodily injury by accident – each accident for the protection of its employees or other similar

17.3. 

Business Interruption Insurance in amounts sufficient to reimburse Tenant (over a 12 month period) for direct 
or indirect loss of earnings attributable to all perils commonly insured against by prudent tenants or attributable to prevention of access to 
the Premises or to the Project as a result of such perils, including, without limitation, reimbursement for payment of rental and all other 
monetary obligations required herein;

Automobile  Liability  with  a  combined  single  limit  of  $3,000,000  per  occurrence  covering  the  operation,  
ownership, maintenance, and use of owned (if any), non-owned, and hired automobiles, bodily injury and property damage, as aforesaid; 
and

17.4. 

17.5. 

In  the  event  Tenant  distributes,  sells  and/or  manufactures  liquor  or  alcoholic  beverages  on  the  Premises,  
Tenant  shall  maintain  liquor  liability  coverage  with  minimum  coverage  limits  of  $3,000,000  per  occurrence  and  $3,000,000  annual 
aggregate,  (which  limits  may  be  met  by  combining  primary  and  excess  liability  policies  limits)  and  also  maintain  the  coverages  and 
coverage limits set forth in Paragraph 15. Notwithstanding anything in this Lease to the contrary, if Tenant serves, sells or maintains liquor 
or alcoholic beverages on Premises, Tenant, at a minimum, shall maintain dram shop coverage (or its equivalent) with limits of $2,000,000 
in accordance with Paragraph 15.  Coverage shall be on a per occurrence form.  Notwithstanding the foregoing, in no event shall Tenant 
be permitted to distribute, sell or manufacture liquor on the Premises without Landlord’s prior written consent, which may be withheld by 
Landlord in its sole and absolute discretion.

18.Form of Tenant’s Insurance Policies.  The minimum limits of policies of insurance required of Tenant under this Lease shall in 
no event limit the liability of Tenant under this Lease.  Such insurance (i) shall name Landlord, American Assets Trust, Inc. and American 
Assets Trust, LP. and any other party with an insurable interest in the Project which the Landlord so specifies by written notice to Tenant, 
as an additional insured, including Landlord's managing agent, American Assets Trust Management, LLC, as such agent may be changed 
from  time  to  time;  (ii)  shall  cover  the  liability  assumed  by  Tenant  under  the  indemnification  provisions  of  this  Lease;  (iii)  shall  consist  of 
"occurrence"  based  coverage,  without  provision  for  subsequent  conversion  to  "claims"  based  coverage  (provided,  however,  Products 
Liability coverage may be “claims made” coverage); (iv) shall be issued by an insurance company having a rating of not less than A VII in 
Best's  Insurance  Guide  or  which  is  otherwise  acceptable  to  Landlord  and  authorized  to  do  business  in  the  state  in  which  the  Project  is 
located; (v)  shall be primary insurance and non-contributing with respect to all Claims thereunder and any policies carried by Landlord and 
that any coverage carried by Landlord shall be excess insurance; (vi) be in form and content reasonably acceptable to Landlord; and (vii) 
shall  provide  that  said  insurance  shall  not  be  canceled  or  modified    in  coverage  unless  30  days'  prior  notice  shall  have  been  given  to
Landlord.  Tenant shall deliver said policy or policies or certificates and applicable endorsements thereof or reasonable evidence that such 
insurance is in place to Landlord on or before the Commencement Date.  In the event Tenant shall fail to procure such insurance, or to 
deliver  such  policies  or  certificate  and  applicable  endorsements,  Landlord  may,  at  its  option  upon  5  business  days'  notice  to  Tenant, 
procure such policies for the account of Tenant unless Tenant provides same within such 5 day period, and the cost thereof shall be paid to 
Landlord  within  5  days  after  delivery  to  Tenant  of  bills  therefore.    Tenant  shall,  within  five  (5)  days  prior  to  the  expiration  of  each  such 
policy, furnish Landlord with a renewal certificate and applicable endorsement of or "binder" extending such policy.  

18.1. Tenant  shall  deliver  all  certificates,  endorsements  and  policies  required  to  be  delivered  to  Landlord  under  this 
Lease by emailing them to aatinsurance@americanassets.com (as such email address may be changed upon written notice from Landlord 
to Tenant).

19.Waiver of Subrogation.    Notwithstanding  anything  to  the  contrary  set  forth  in  this  Lease, Landlord  and  Tenant  release  each 
other,  Tenant's  Invitees,  Landlord's  guests,  invitees,  customers  and  licensees  (collectively,  "Landlord's Invitees")  and  Landlord’s  agents, 
affiliates, officers, directors and employees from all claims for damage, loss, or injury to the Project, to Tenant's Personal Property, and to 
the fixtures and Alterations of either Landlord or Tenant in or on the Project to the extent such damage, loss or injury is covered by any 
insurance  policies  carried  by  Landlord  and  Tenant  and  in  force  at  the  time  of  such  damage,  or  which  would  have  been  covered  by 
insurance policies required by this Lease to be carried by Tenant, but which Tenant failed to carry.  Subject to the remaining provisions of 
this  Paragraph,  Landlord  and  Tenant  shall  each  cause  all  insurance  policies  obtained  by  it  pursuant  to  this  Lease  to  provide  that  the 
insurance  company  waives  all  right  of  recovery  by  way  of  subrogation  against  Landlord,  American  Assets  Trust,  Inc.,  American  Assets 
Trust,  L.P.,  American  Assets  Trust  Management,  LLC,  and  Landlord’s  agents,  employees  and  representatives  and  Tenant  and  Tenant’s 
agents, employees and representatives  in connection with any damage, loss, or injury covered by such policy.  If any such policy cannot 
be obtained with a waiver of subrogation, or is obtainable only by the payment 

American Assets Trust – Lease Form 1/31/2023

of an additional premium charge above that charged by insurance companies issuing policies without waiver of subrogation endorsements, 
the party undertaking to obtain such policy (the "Undertaking Party") shall so notify the other party (the "Notified Party").  The Notified Party 
shall,  within  10  days  after  delivery  of  such  notice,  either  obtain  such  policy  from  a  company  that  is  reasonably  satisfactory  to  the 
Undertaking Party and that will issue such policy with a waiver of subrogation endorsement, or agree to pay the additional premium if such 
policy is obtainable at additional cost.  If such policy cannot be obtained with a waiver of subrogation endorsement or the Notified Party 
refuses to pay such additional premium, then the Undertaking Party shall not be required to obtain a waiver of subrogation endorsement 
with  respect  to  such  policy.    Notwithstanding  the  foregoing,  if  any  claim  to  which  the  foregoing  release  by  Landlord  and  waiver  of 
subrogation provision would apply is for an amount which is less than Landlord’s applicable deductible, and Landlord elects not to submit 
such claim to its insurer, then the provisions of the foregoing release by Landlord shall not be applicable.

20.Landlord's Insurance.  Landlord shall, at its election, maintain any of the following insurance, in such amounts and with such 
limits  as  Landlord  shall  determine  in  its  reasonable  discretion  for  projects  of  a  similar  nature:    (i)  public  liability  and  property  damage 
insurance, and products liability insurance; (ii) fire and extended coverage and special form insurance for the full replacement cost, with 
coverage with respect to increased costs due to building ordinances, demolition coverage, and sprinkler leakage coverage; (iii) boiler and 
machinery  insurance;  (iv)  fidelity  insurance;  (v)  plate‑glass  insurance;  (vi)  earthquake  insurance;  (vii)  terrorism  insurance,  (viii)  flood 
insurance; (ix) rental interruption and/or business interruption insurance; and (x) pollution legal liability insurance.  The premiums, costs, 
expenses, and commercially reasonable deductibles (or similar costs or charges) of and/or with respect to any such insurance (all of the 
preceding, collectively, "Insurance Expenses") shall be included in Operating Expenses. Any such coverage may be part of an umbrella or 
blanket policy, whereupon the premiums, costs, and expenses hereof will be reasonably apportioned between the Building and the other 
properties  so  included  under  such  policy(ies).    Landlord  reserves  the  right  to  self-insure  against  any  or  all  loss,  damage,  liability  or  risk 
related  to  the  Project  rather  than  maintain  traditional  insurance  policies,  in  which  event  Landlord  shall  have  right  to  include  within 
Insurance Expenses passed through to Tenant an amount equal to what Insurance Expenses reasonably would have been had Landlord 
maintained traditional insurance policies.

21.Personal Property Taxes.  Tenant shall pay before delinquency all taxes, assessments, license fees, and other charges that 
are levied or assessed against, or based upon the value of, Tenant’s personal property installed or located in or on the Premises including 
without limitation trade fixtures, furnishings, equipment, Alterations, and inventory (collectively, “Tenant’s Personal Property”).  On written 
demand by Landlord, Tenant shall furnish Landlord with satisfactory evidence of such payments.   If any such taxes, assessments, license 
fees, and/or other charges are levied against Landlord or Landlord’s property, or if the assessed value of the Premises is increased by the 
inclusion  of  a  value  placed  on  Tenant’s  Personal  Property,  and  if  Landlord  pays  such  taxes,  assessments,  license  fees,  and/or  other 
charges  or  any  taxes  based  on  the  increased  assessments  caused  by  Tenant’s  Personal  Property,  then  Tenant,  on  demand,  shall 
immediately reimburse Landlord, as Additional Rent, for the sum of such taxes, assessments, license fees, and/or other charges so levied 
against  Landlord,  or  the  proportion  of  taxes  resulting  from  such  increase  in  Landlord’s  assessment.      Landlord  may,  at  its  election,  pay 
such  taxes,  assessments,  license  fees,  and/or  other  charges  or  such  proportion,  and  receive  such  reimbursement,  regardless  of  the 
validity of the levy.

22.Alterations.  Tenant shall not make any alterations, improvements, additions, installations, or changes of any nature in or to 
the Premises (any of the preceding, “Alterations”) unless Tenant first obtains Landlord’s written consent to such Alteration and otherwise 
complies with the provisions of this Paragraph 22; provided, however, that no such consent will be required in connection with any Minor 
Alterations (as defined below).  

22.1. Request for Consent.  At least 15 days prior to making any Alterations, Tenant shall submit to Landlord, in written 
form, proposed detailed plans of such Alterations, which plans must (i) in the case of a Minor Alterations, be in sufficient detail to, among 
other things, provide Landlord with reasonable evidence that such Alterations are of a nature that Landlord’s consent is not required, and 
(ii) in the case of any other Alterations, in sufficient detail to allow Landlord and its consultants to fully evaluate the proposed Alterations 
and  their  affect  upon  the  Premises  and  the  Project.    Landlord  will  not  unreasonably  withhold,  condition,  or  delay  its  consent  to  any 
Alterations for which consent is required; provided, however that in the case of exterior Alterations or Alterations which will be visible from 
outside  the  Premises  or  which  will  affect  any  structural  components  of  the  Project,  Landlord  shall  have  the  right  to  grant  or  withhold  its 
consent in the exercise of its sole discretion.  In addition to the foregoing requirements, if the proposed Alteration requires approval by or 
notice  to  the  lessor  of  a  ground  or  underlying  lease  or  the  holder  of  a  deed  of  trust  encumbering  the  Project,  no  Alteration  shall  be 
commenced until 

American Assets Trust – Lease Form 1/31/2023

 19

 
 
 
 
 
 
such approval has been received, or such notice has been given, as the case may be, and all applicable conditions and provisions of said 
superior lease or deed of trust with respect to the proposed Alterations have been met or complied with at Tenant’s sole cost and expense; 
and Landlord, if it approves the Alteration, will request such approval or give such notice expeditiously, as the case may be, and thereafter 
take reasonable diligent measures to obtain such approval.

22.2. Minor Alterations.   Notwithstanding anything to the contrary contained herein, minor, interior cosmetic Alterations 
such as painting, wall papering, carpeting or hanging pictures or moving furniture and temporary partitions or cubicles (the aggregate cost 
of which will not exceed $10,000, and which Alterations will not be visible from outside the Premises or affect any structural components of 
the Project) will not require Landlord’s prior consent so long as (i) Tenant notifies Landlord in accordance with Paragraph 22.1(i) and (ii) 
Tenant  complies  with  all  reasonable  conditions  which  may  be  imposed  by  Landlord  including,  but  not  limited  to,  the  requirements  of 
Paragraph 22.3 below, Landlord’s selection of specific contractors or construction techniques and the requirements of the attached Exhibit 
“C”.  Any Alterations meeting the foregoing requirements to avoid the necessity of obtaining Landlord’s consent are referred to herein as a 
“Minor Alterations”.

22.3. Additional Requirements.  Tenant shall, prior to the commencement of any Alterations, and at Tenant's sole cost 
and expense, (i) acquire (and deliver to Landlord a copy of) any required permit from the appropriate governmental agencies to make such 
Alterations  (any  conditions  of  which  permit  Tenant  shall  comply  with,  at  Tenant’s  sole  cost  and  expense,  in  a  prompt  and  expeditious 
manner), (ii) provide Landlord with 10 business days’ prior written notice of the date the installation of the such Alterations is to commence, 
so that Landlord can post and record an appropriate notice of non-responsibility, (iii) pay Landlord the reasonable costs and expenses of 
Landlord  for  architectural,  engineering,  or  other  consultants  which  reasonably  may  be  incurred  by  Landlord  in  determining  whether  to 
approve  any  such  Alterations  (excluding  Minor  Alterations),  and  (iv)  if  applicable,  obtain  (and  deliver  to  Landlord  proof  of)  reasonably 
adequate additional workers compensation insurance with respect to any of Tenant’s employees installing or involved with such Alterations 
(which  insurance  Tenant  shall  maintain  on  an  occurrence  basis  in  force  until  completion  of  the  Alterations).      In  addition,  Tenant  shall 
comply  with  all  reasonable  conditions  which  may  be  imposed  by  Landlord  relative  to  such  Alterations  including,  but  not  limited  to,  (1) 
Landlord’s selection of specific contractors or construction techniques and (2) the requirements of the attached Exhibit “C”  applicable  to 
Tenant’s Work. Notwithstanding anything to the contrary in this Paragraph 22.3, in no event shall Tenant remove any ceiling tiles or ceiling 
gridwork or lighting without Landlord's prior written consent, and any such consent may be conditioned upon requiring Tenant to restore the 
Premises to their prior condition upon termination of the Term and to secure Tenant's obligation to so restore the Premises.

22.4. Ownership of Alterations.   Except for Tenant's trade fixtures, all Alterations shall, upon the Expiration Date of this 
Lease,  become  the  property  of  Landlord  and  shall  remain  on  and  be  surrendered  with  the  Premises  on  the  Expiration  Date;  provided, 
however that Landlord may, at its election, require Tenant to remove any or all of the Alterations, provided that Landlord notifies Tenant in 
writing prior to commencement of the Alterations.  If Landlord so elects that the Alterations be removed, Tenant shall, at its sole cost and 
expense, on or before the Expiration Date, repair and restore the Premises to the condition of the Premises prior to the installation of the 
Alterations which are to be removed.  Tenant shall be solely responsible for and shall pay all costs and expenses for Alterations and other 
construction done or caused to be done by Tenant and Tenant shall keep the Premises free and clear of all mechanics’ and materialmen’s 
liens resulting from or relating to any Alterations or other construction.   Tenant may, at its election, contest the correctness or validity of 
any such lien provided that (a) within 20 days after written demand by Landlord, Tenant procures and records a lien release bond, issued 
by a corporation satisfactory to Landlord and authorized to issue surety bonds in California, in an amount equal to 125% of the amount of 
the claim of lien, which bond meets the requirements of California Civil Code Section 8424 or any successor statute, and (b) Landlord may, 
at its election, require Tenant to pay Landlord’s attorneys’ fees, costs and expenses incurred in participating in such an action.

22.5. Control over Tenant’s Wi-Fi Use.

(a) Wi-Fi.  Tenant  shall  have  the  right  to  install,  at  its  sole  cost  and  expense,  a  wireless  intranet,  Internet,  and 
communications  network  (also  known  as  “Wi-Fi”)  utilizing  IEEE  802.XX  protocols  within  the  Premises  for  the  use  of  Tenant  and  its 
employees  (the  “Network”)  subject  to  the  provisions  of  this  Paragraph  22.5  and  the  other  provisions  of  Paragraph  22.    All 
telecommunications service providers shall be subject to Landlord’s prior written approval.

No  solicitation.  Tenant  shall  not  solicit,  suffer,  or  permit  other  tenants  or  occupants  of  the  Building  to  use  the 
Network or any other communications service, including, without limitation, any wired or wireless Internet service that passes through, is 
transmitted

through, or emanates from the Premises.

(c)

Interference.  Tenant  agrees  that  the  Network,  Tenant’s  communications  equipment  and  the  communications 
equipment  of  Tenant’s  service  providers  located  in  or  about  the  Premises  or  installed  in  the  Building  to  service  the  Premises  including, 
without limitation, any antennas, switches, or other equipment (collectively, “Tenant’s Communications Equipment”) shall be of a type and, 
if applicable, a frequency that will not cause radio frequency, electromagnetic, or other interference to any other party or any equipment of 
any  other  party  including,  without  limitation,  Landlord,  other  tenants,  or  occupants  of  the  Building.  Landlord  reserves  the  right  to  cause 
Tenant to operate on a channel or frequency band that Landlord selects, in its sole discretion.  In the event that Tenant’s Communications 
Equipment causes or is believed by Landlord to cause any such interference, upon receipt of notice from Landlord of such interference,
Tenant will promptly take all steps necessary to correct and eliminate the interference. If the interference is not eliminated within 24 hours 
(or  a  shorter  period  if  Landlord  believes  a  shorter  period  to  be  appropriate)  then,  upon  notice  from  Landlord,  Tenant  shall  use  other 
channels or frequencies as determined solely by Landlord, or, at Landlord’s election, shut down the Tenant’s Communications Equipment 
pending  resolution  of  the  interference  (with  the  exception  of  intermittent  testing  upon  prior  notice  to,  and  with  the  prior  approval  of, 
Landlord).    Landlord  shall  have  no  obligation  or  liability  with  respect  to  any  interruption,  curtailment  or  discontinuance  of 
telecommunications services.

cost and expense.

(d)

Maintenance.  Tenant shall maintain Tenant’s Telecommunications Equipment in good order and repair at its sole 

other rights to other tenants and/or occupants of the Building and to telecommunications service providers.

(e)

Acknowledgment.  Tenant acknowledges that Landlord has granted and/or may grant lease rights, licenses, and 

23.Surrender of Premises and Holding Over.  

23.1. Surrender.    On  the  Expiration  Date  or  earlier  termination  of  the  Term,  Tenant  shall  surrender  to  Landlord  the 
Premises and all Alterations (except for Alterations that Tenant is obligated to remove as expressly set forth in Paragraph 22.4 above) in 
the condition received, less any normal wear and tear, free of trash and debris including cleaning of all flooring; all walls shall be patched 
and  painted;  all  signage  installed  by  Tenant  on  any  portion  of  the  Buildings  or  Project  shall  be  removed  and  the  surfaces  repaired, 
including restoration of the signage mounting surfaces to their pre-existing condition; all sign circuits, electrical circuits, and lighting fixtures 
shall  be  in  good  operating  condition;  all  roof  penetrations  arising  from  Tenant’s  occupancy  of  the  Premises  shall  be  in  a  watertight 
condition; and all doors, windows, locks, and hardware shall be in operable condition upon the termination of this Lease.   Tenant shall 
additionally,  as  of  the  Expiration  Date,  remove  all  of  Tenant's  Personal  Property  and  all  electric,  data  and  voice  cabling  installed  in  the 
Premises,  or  behind  or  above  any  ceiling  or  wall  in,  on,  or  about  the  Premises  and  perform  all  repairs  and  restoration  required  by  the 
removal of any such cabling, Alterations or Tenant's Personal Property, as applicable, and Tenant shall surrender to Landlord all keys to 
the  Premises  (including  without  limitation  any  keys  to  any  exterior  or  interior  doors).    Landlord  may  elect  to  retain  or  dispose  of  in  any 
manner any Alterations or Tenant's Personal Property that Tenant does not remove from the Premises on or before the Expiration Date or 
earlier termination date of the Term of this Lease by giving written notice to Tenant.  Any such Alterations or Tenant's Personal Property 
that  Landlord  elects  to  retain  or  dispose  of  shall  immediately  upon  notice  to  Tenant  vest  in  Landlord.    Tenant  waives  all  claims  against 
Landlord for any damage to Tenant resulting from Landlord's retention or disposition of any such Alterations or Tenant's Personal Property.  
Tenant  will  be  liable  to  Landlord  for  Landlord's  costs  for  storing,  removing  (including  related  restoration  work),  or  disposing  of  any  such 
Alterations (that were required to be removed by Landlord under this Lease) or Tenant's Personal Property.  If Tenant fails to surrender the 
Premises to Landlord on the Expiration Date (or earlier termination of the Term) in the condition required by this Paragraph 23.1, Tenant 
shall  indemnify,  defend,  and  hold  harmless  the  Landlord  from  and  against  all  third  party  liabilities,  damages,  losses,  costs,  expenses, 
attorneys' fees and costs, and claims resulting from such failure, including without limitation any claim for damages made by a succeeding 
tenant.  

23.2. Holding  Over.    If  Tenant,  with  Landlord's  consent,  remains  in  possession  of  the  Premises  after  the  Expiration 
Date, such possession by Tenant shall be deemed to be a month‑to‑month tenancy terminable on 30‑days' written notice given at any time 
by  Landlord  or  Tenant.    During  any  such  month‑to‑month  tenancy,  or  any  other  holdover  tenancy  which  is  without  Landlord's  consent, 
Tenant shall pay, as Basic Monthly Rent, (i) 103% of the Basic Monthly Rent in effect immediately prior to the Expiration Date for the first 
two (2) months of such holdover tenancy in the event that Tenant has provided Landlord with a minimum of 9 months’ written notice of 
such intent (should Tenant fail to provide Landlord with such notice, Tenant shall be 

American Assets Trust – Lease Form 1/31/2023

 21

 
 
 
 
 
required  to  pay  150%  of  the  Basic  Monthly  Rent  in  effect  immediately  prior  to  the  Expiration  Date),  and  150%  of  the  Additional  Rent  in 
effect immediately prior to the Expiration Date; which rental amount Tenant acknowledges is fair and reasonable under all of the facts and 
circumstances existing as of the date of this Lease. All provisions of this Lease except for those pertaining to Term shall apply to any such 
tenancy. If Tenant holds over after the Expiration Date without the express written consent of Landlord, Tenant shall become a tenant at 
sufferance only, at a rental rate equal to 150% of the Basic Monthly Rent and 150% of the Additional Rent in effect immediately prior to 
expiration of the Term (prorated on a daily basis), and otherwise subject to the terms, provisions, and conditions herein specified, so far as 
applicable.  Acceptance by Landlord of rent after such expiration or earlier termination shall not constitute consent to a holdover tenancy 
hereunder or result in a renewal. The foregoing provisions this Paragraph 23.2 are in addition to, and do not affect, Landlord's right of re-
entry  or  any  rights  of  Landlord  hereunder  or  as  otherwise  provided  by  Laws.  Landlord  expressly  reserves  the  right  to  require  Tenant  to
surrender  possession  of  the  Premises  to  Landlord  as  provided  in  this  Lease  upon  expiration  or  other  termination  of  this  Lease.    The 
provisions of this Paragraph 23.2 shall not be considered to limit or constitute a waiver of any other rights or remedies of Landlord provided 
in this Lease or at Laws or equity.  In addition to the foregoing, if Tenant fails to surrender the Premises to Landlord on the Expiration Date 
in  the  condition  required  by  Paragraph  23.1,  above,  Tenant  shall  indemnify,  defend,  and  hold  harmless  Landlord  from  and  against  all 
actions,  demands,  liabilities,  damages,  losses,  costs,  expenses,  attorneys’  fees  and  costs,  and  claims  resulting  from  such  failure, 
including, without limitation, any claim for damages made by a succeeding tenant.

24.Default.  The occurrence of any of the following shall constitute a material default and breach of this Lease by Tenant (each, 

an “Event of Default”):

24.1. The abandonment (as defined in the California Civil Code 1951.3) of the Premises by Tenant.

within 3 business days after delivery of written notice from Landlord specifying such failure to pay.

24.2. Tenant's  failure  to  make  any  payment  of  Rent  (including  late  charges)  when  due,  and  such  failure  is  not  cured 

24.3. Tenant’s  failure  to  timely  deliver  an  estoppel  certificate  to  Landlord  in  accordance  with  the  provisions  of 
Paragraph 41, below, or to timely deliver a subordination, non-disturbance, and attornment agreement in accordance with the provisions of 
Paragraph 40, below, after notice and 3 business days in which to cure.

24.4. Tenant’s  failure  to  restore  the  Security  Deposit  pursuant  to  Paragraph  6,  above,  within  10  business  days  after 
written notice from Landlord demanding such restoration; provided, however, that any such notice shall be in lieu of, and not in addition to, 
any notice required under applicable unlawful detainer statutes.

Building or Project.

24.5. Tenant is in default beyond any notice and cure period under any other lease or agreement with Landlord at the 

24.6. Tenant's failure to observe or perform any of the provisions of this Lease to be observed or performed by Tenant, 
other than described in the preceding six paragraphs, where such failure shall continue for a period of 20 days after written notice of such 
failure from Landlord to Tenant (or such lesser or greater cure period as explicitly set forth in the Lease); provided, however, that any such 
notice shall be in lieu of, and not in addition to, any notice required under applicable unlawful detainer statutes; and provided further, that if 
the nature of Tenant's default is such that more than 20 days are reasonably required for its cure, then Tenant shall not be deemed to be in 
default if Tenant commenced such cure within such 20 day period and thereafter diligently prosecutes such cure to completion within 60 
days after Landlord's written notice.  Such written notice will be deemed to satisfy the statutory notice requirements of applicable unlawful 
detainer statutes and will be in lieu thereof (and not in addition thereto).  Tenant acknowledges that Landlord only agreed to the inclusion of 
such notice requirement on the condition that such notice would constitute the legally required notice following a default and Tenant waives 
any claim, counterclaim, or defense to any action relating to an unlawful detainer on the basis that such notice, was insufficient to meet 
such statutory notice requirement or was in any other manner defective, and Tenant agrees that it will be estopped from raising any such 
argument in any action by Landlord.

24.7. The making by Tenant of any general arrangement or assignment for the benefit of creditors; Tenant's becoming 
bankrupt,  insolvent  or  a  “debtor”  as  defined  in  11  U.S.C.  Section  101,  or  any  successor  statute  (unless,  in  the  case  of  a  petition  filed 
against  Tenant,  such  petition  is  dismissed  within  60  days  after  its  original  filing);  the  institution  of  proceedings  under  the  bankruptcy  or 
similar Laws in which Tenant is the debtor or bankrupt; the appointing of a trustee 

American Assets Trust – Lease Form 1/31/2023

 22

 
 
 
 
  
 
 
 
 
 
or receiver to take possession of substantially all of Tenant's assets located at the Premises or of Tenant's interest in this Lease (unless 
possession  is  restored  to  Tenant  within  60  days  after  such  taking);  the  attachment,  execution,  or  judicial  seizure  of  substantially  all  of 
Tenant's  assets  located  at  the  Premises  or  Tenant's  interest  in  this  Lease  (unless  such  attachment,  execution,  or  judicial  seizure  is 
discharged within 60 days after such attachment, execution, or judicial seizure); or, if Tenant is a partnership or consists of more than one 
person or entity, any partners of the partnership or any such other person or entity becoming bankrupt or insolvent or making a general 
arrangement or assignment for the benefit of creditors.

25.Landlord's Remedies.    Landlord  shall  have  the  following  remedies  if  Tenant  commits  an  Event  of  Default  under  this  Lease.  
These remedies are not exclusive, but are cumulative and in addition to any remedies provided elsewhere in this Lease or now or later 
allowed by Laws.

25.1. Continuation of Lease.  No act by Landlord shall terminate Tenant's right to possession unless Landlord notifies 
Tenant in writing that Landlord elects to terminate Tenant's right to possession.  As long as Landlord does not terminate Tenant's right to 
possession, Landlord may (i) continue this Lease in effect, (ii) continue to collect Rent when due and enforce all the other provisions of this 
Lease, and (iii) enter the Premises and relet them, or any part of them, to third parties for Tenant's account, for a period shorter or longer 
than  the  remaining  Term  of  this  Lease.    Tenant  shall  immediately  pay  to  Landlord  all  costs  Landlord  incurs  in  such  reletting,  including, 
without limitation, brokers' commissions, attorneys' fees, advertising costs, and expenses of remodeling the Premises for such reletting.  
The parties agree that Landlord is to have the remedy described in California Civil Code Section 1951.4 (which effectively provides that a 
lessor may continue a lease in effect after the lessee’s breach and recover rent as it becomes due), and the Tenant hereby acknowledges 
that this Lease meets the requirements of such statutory provision and that Tenant’s rights to sublet or assign hereunder are subject only 
to reasonable limitations.

25.2. Rent from Reletting.  If Landlord elects to relet all or any portion of the Premises as permitted above, rent that 
Landlord  receives  from  such  reletting  shall  be  applied  to  the  payment  of,  in  the  following  order  and  priority,  (i)  any  indebtedness  from 
Tenant  to  Landlord  other  than  Rent  due  from  Tenant,  (ii)  all  costs  incurred  by  Landlord  in  such  reletting,  and  (iii)  Rent  due  and  unpaid 
under  this  Lease.    After  applying  such  payments  as  referred  to  above,  any  sum  remaining  from  the  rent  Landlord  receives  from  such 
reletting shall be held by Landlord and applied in payment of future Rent as it becomes due under this Lease.  In no event shall Tenant be 
entitled to any excess rent received by Landlord unless and until all obligations of Tenant under this Lease, including all future obligations, 
are satisfied in full. 

25.3. Termination  of  Tenant's  Right  to  Possession.    Landlord  may  terminate  Tenant's  right  to  possession  of  the 
Premises at any time, by notifying Tenant in writing that Landlord elects to terminate Tenant's right to possession.  Such written notice will 
result in the immediate termination of this Lease upon the date such right of possession is terminated.   Upon termination of this Lease, 
Landlord has the right to recover from Tenant (i) the worth at the time of the award of the unpaid Rent which had been earned at the time 
of such termination, (ii) the worth at the time of the award of the amount by which the unpaid Rent which would have been earned after 
such termination until the time of award exceeds the amount of such loss of Rent that Tenant proves could have been reasonably avoided, 
(iii) the worth at the time of the award of the amount by which the unpaid Rent for the balance of the Term after the time of award (had 
there been no such termination) exceeds the amount of such loss of Rent that Tenant proves could be reasonably avoided, and (iv) any 
other amount necessary to compensate Landlord for all detriment proximately caused by Tenant's failure to perform Tenant's obligations 
under this Lease or in the ordinary course of things would be likely to result therefrom, and (v) the unamortized cost of broker commissions 
paid for this Lease, the unamortized cost of any improvements to the Premises installed by or paid for by Landlord, and full reimbursement 
for  any  free  or  abated  rent  occupancy  periods  granted  to  Tenant.    The  “worth  at  the  time  of  the  award”  of  the  amounts  referred  to  in 
clauses (i) and (ii) above is to be computed by allowing interest at the Default Rate.  The “worth at the time of the award” of the amount 
referred to in clause (iii) above is to be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San 
Francisco  at  the  time  of  award  plus  1%.    If  Landlord  takes  possession  of  the  Premises  pursuant  to  the  authority  herein  granted,  then 
Landlord shall have the right to keep in place and use all of the furniture, fixtures and equipment at the Premises, including that which is 
owned by or leased to Tenant at all times prior to any foreclosure thereon by Landlord or repossession thereof by any lessor thereof or 
third  party  having  a  lien  thereon.    Landlord  shall  also  have  the  right  to  remove  from  the  Premises  (without  the  necessity  of  obtaining  a 
distress warrant, writ of sequestration or other legal process and without being liable for prosecution or any claim for damages therefor) all 
or any portion of such furniture, fixtures, equipment and other property located thereon and place the same in storage at any place within 
the county in which the 

American Assets Trust – Lease Form 1/31/2023

Premises  is  located  or  dispose  of  the  same;  and  in  such  event,  Tenant  shall  be  liable  to  Landlord  for  costs  incurred  by  Landlord  in 
connection  with  such  removal,  storage,  and/or  disposal  and  shall  indemnify  and  hold  Landlord  harmless  from  all  loss,  damage,  cost, 
expense, and liability in connection with such removal, storage and/or disposal.  Landlord shall also have the right to relinquish possession 
of  all  or  any  portion  of  such  furniture,  fixtures,  equipment,  and  other  property  to  any  person  ("Claimant”)  claiming  to  be  entitled  to 
possession thereof who presents to Landlord a copy of any instrument purporting to have been executed by Tenant (or any predecessor of 
Tenant) granting Claimant the right under various circumstances to take possession of such furniture, fixtures, equipment or other property, 
without  the  necessity  on  the  part  of  Landlord  to  inquire  into  the  authenticity  of  said  instrument  and  without  the  necessity  of  Landlord's 
making any investigation or inquiry as to the validity of the factual or legal basis upon which Claimant purports to act; and Tenant agrees to 
indemnify,  defend  and  hold  Landlord  Parties    harmless  from  all  cost,  expense,  loss,  damage,  and  liability  incident  to  Landlord's 
relinquishment  of  possession  of  all  or  any  portion  of  such  furniture,  fixtures,  equipment,  or  other  property  to  Claimant.    Should  Tenant 
abandon the Premises and leave property therein, Landlord may elect whether or not to accept the property, liquidate said property and 
apply  the  proceeds  against  any  sums  due  and  owing  by  Tenant,  or  to  dispose  of  said  property,  and  Tenant  waives  any  claim  to  such 
property  after  any  such  abandonment.    For  purposes  of  the  foregoing,  Tenant  shall  be  deemed  to  have  abandoned  its  interest  in  such 
property if the same is not removed from the Premises by Tenant within 10 days after Landlord's proper demand that Tenant remove same, 
or within 10 days after expiration or earlier termination of this Lease, whichever first occurs.  Notwithstanding the foregoing, Landlord shall 
also  be  entitled  to  exercise  its  rights  pursuant  to  California  Civil  Code  Section  1980  et.  seq.  with  respect  to  the  disposition  of  Tenant's 
personal property. The provisions of this Paragraph 25.3 shall additionally apply at the time of Tenant's surrender of the Premises pursuant 
to Paragraph 20.1.  The provisions hereof shall survive the termination of this Lease.

25.4. Landlord's Right to Cure Default.  Landlord, at any time after Tenant commits an Event of Default, may cure such 
Event of Default at Tenant's sole cost.  If Landlord at any time, by reason of Tenant's default or breach, pays any sum or does any act that 
requires the payment of any sum, such sum shall be due immediately from Tenant to Landlord at the time such sum is paid, along with a 
supervisory fee in the amount of 10% of such amount so expended by Landlord, and shall be deemed Additional Rent under this Lease.  If 
Tenant fails to timely pay any amount due under this Paragraph within 10 business days of receipt of Landlord’s invoice for such costs, 
then (without curing such default) interest at the Default Rate shall accrue (and be immediately payable) on such overdue amount until it is 
paid.  

25.5. Enforcement Costs.  All costs and expenses incurred by Landlord in connection with collecting any amounts and 
damages  owing  by  Tenant  pursuant  to  the  provisions  of  this  Lease,  or  to  enforce  any  provision  of  this  Lease,  including  reasonable 
attorneys' fees, whether or not any action is commenced by Landlord, shall be paid by Tenant to Landlord upon demand.  If Tenant fails to 
timely  pay  any  amount  due  under  this  Paragraph,  then  (without  curing  such  default)  interest  at  the  Default  Rate  shall  accrue  (and  be 
immediately payable) on such overdue amounts until it is paid. 

25.6.

Independent  Covenants.    If  Landlord  shall  commence  any  proceeding  for  nonpayment  of  Rent,  or  any  other 
payment of any other kind to which Landlord may be entitled, or which it may claim hereunder, Tenant will not interpose any counterclaim 
or  setoff  of  whatever  nature  or  description,  (other  than  compulsory  counterclaim)  in  such  proceedings.    The  parties  hereto  specifically 
agree  that  Tenant's  covenants  to  pay  Rent  or  any  other  payments  required  of  it  hereunder  are  independent  of  all  other  covenants  and 
agreements herein contained and, as such, among other things, Tenant shall have no offset rights against the Rent payable hereunder by 
Tenant  to  Landlord.    The  foregoing  shall  not  be  construed  as  a  waiver  of  Tenant's  right  to  assert  any  such  claim  in  a  separate  action 
brought by Tenant against Landlord nor a waiver of any compulsory counterclaim under applicable Laws.

26.Interest and Late Charges.  Late payment by Tenant to Landlord of Rent or other charges will cause Landlord to incur costs 
not contemplated by this Lease, the exact amount of which would be impracticable or extremely difficult to fix.  Such costs include, without 
limitation, processing, collection and accounting charges, and late charges that may be imposed on Landlord by the terms of any deed of 
trust covering the Premises.  Therefore, if any Rent or other charge (in the form of good funds) is not received by Landlord within 10 days 
of its due date, then, without any requirement for notice to Tenant, Tenant shall owe and pay to Landlord an additional sum of five percent 
(5%) of such overdue amount as a late charge.  Such late charge represents a fair and reasonable estimate of the costs that Landlord will 
incur by reason of any late payment by Tenant, and therefore this Paragraph is reasonable under the circumstances existing at the time 
this Lease is made.  Acceptance of such late charge by Landlord shall not constitute a waiver or cure of Tenant's default with respect to 
such overdue amount, nor prevent Landlord from

exercising  any  of  the  other  rights  and  remedies  available  to  Landlord  under  this  Lease  any  or  all  of  which  may  be  exercised  before, 
concurrently, or after Landlord’s exercise of its rights hereunder.  In addition to the late charge payable by Tenant, as provided above, if 
any such Rent or other charge is not paid within 30 days of the date such Rent or other charge was due, then Tenant shall pay to Landlord 
interest on such overdue Rent or other charge (from such 30th day until all amounts, including interest, are paid in full) at the rate of 7% per 
annum above the “reference rate” announced from time to time by Bank of America, NT&SA or the maximum amount permitted by Laws, 
whichever is less (the “Default Rate”).  If such reference rate ceases to be announced, then a comparable “prime rate” shall be utilized, as
selected by Landlord.  Notwithstanding the foregoing, in any consecutive twelve (12) month period, Tenant shall not be obligated to pay a 
late charge on the first payment which Landlord does not receive when due, unless Tenant does not pay such amount within five (5) days 
after written notice from Landlord that such payment is past due. 

27.Landlord  Default  –  Tenant’s  Remedies.    Landlord  shall  not  be  in  default  hereunder  unless  Landlord  fails  to  perform  the 
obligations required of Landlord within a reasonable time, but in no event later than 30 days after notice by Tenant to Landlord, and to the 
holder of any first mortgage or deed of trust covering the Premises, whose name and address shall have theretofore been furnished to 
Tenant,  specifying  the  nature  of  Landlord's  failure  to  perform;  provided,  however,  that  if  the  nature  of  Landlord's  obligation  is  such  that 
more than 30 days are required for performance, then Landlord shall not be in default if Landlord commences performance within such 30-
day period and thereafter diligently prosecutes the same to completion.  In no event shall Tenant have the right to terminate this Lease as 
a  result  of  Landlord's  default,  and  Tenant's  remedies  shall  be  limited  to  monetary  damages;  provided,  however,  that  in  no  event  shall 
Landlord be liable under any circumstances for any consequential damages incurred by Tenant, including, without limitation, any injury to, 
or interference with, Tenant's business (including any loss of profits), arising in connection with this Lease.  Nothing herein contained shall 
be interpreted to mean that Tenant is excused from paying Rent due hereunder as a result of any default by Landlord.

28.Quarterly  Payments.    If  a  late  charge  is  payable  under  this  Lease,  whether  or  not  collected,  for  two  installments  of  Basic 
Monthly  Rent  or  Additional  Rent  due  under  this  Lease  during  any  one  calendar  year  during  the  Term,  then  Basic  Monthly  Rent  and 
Additional Rent shall automatically become due and payable quarterly in advance, rather than monthly.  All monies paid to Landlord under 
this  Paragraph  may  be  commingled  with  other  monies  of  Landlord  and  shall  not  bear  interest.    If  Tenant  breaches  any  provision  of  this
Lease,  then  any  balance  remaining  from  funds  paid  to  Landlord  under  the  provisions  of  this  Paragraph  may,  at  Landlord's  election,  be 
applied to the payment of any monetary default of Tenant in lieu of being applied to the payment of personal property taxes, real property 
taxes and insurance premiums.      Further, if three or more installments of Basic Monthly Rent or Additional Rent due under this Lease, or 
if  any  three  payments  made  by  Tenant  in  the  form  of  a  personal  or  business  check  are  returned  by  the  bank  it  was  drawn  upon  for 
whatever reason, including, but not limited to, insufficient funds, then Landlord, at Landlord’s option, may require Tenant to submit all future 
payments to Landlord in the form of a certified cashier’s check, money order, or by wire transfer with all wire transfer fees of both Landlord 
and Tenant being the responsibility of Tenant.  Tenant’s obligation to provide payment in the aforementioned manner shall continue in full 
force  and  effect  until  Landlords,  in  its  reasonable  discretion,  determines  otherwise.    Tenant  further  agrees  to  reimburse  Landlord,  as 
Additional Rent, Landlord’s actual costs imposed by Landlord’s bank or financial institution arising from Tenant’s returned check(s).  These 
costs shall be in addition to any late charges payable by Tenant pursuant to this Lease.

29.Destruction.    If  the  Building  is  totally  or  partially  destroyed  during  the  Term,  rendering  the  Premises  totally  or  partially 
inaccessible or unusable, then, subject to the remainder of this Paragraph 29, (i) Landlord shall promptly commence work necessary to 
restore the Building to substantially the same condition as it was in immediately before such destruction and shall diligently prosecute such 
restoration work until completed, (ii) Landlord shall not be required to restore Tenant's Alterations or Tenant's Personal Property, unless 
they are fixtures in the Premises and they are specifically covered by insurance proceeds received by Landlord, such excluded items being 
the  sole  responsibility  of  Tenant  to  restore,  (iii)  such  destruction  shall  not  terminate  this  Lease  (except  as  provided  below),  and  (iv)  all 
obligations of Tenant under this Lease shall remain in effect, except that the Basic Monthly Rent and Additional Rent shall be abated or 
reduced,  between  the  date  of  such  destruction  and  the  date  of  Substantial  Completion  of  restoration,  by  the  ratio  of  (a)  the  Rentable 
Square  Footage  of  the  Premises  rendered  unusable  or  inaccessible  by  the  destruction,  to  (b)  the  Rentable  Square  Footage  of  the 
Premises prior to such destruction.  Notwithstanding anything to the contrary in this Paragraph, either party shall have 10 business days 
from  the  date  of  Landlord’s  determination  that  this  sentence  applies  to  the  subject  destruction/reconstruction,  in  which  to  terminate  this
Lease if Landlord determines that (1) it will likely take more than either (A) 330 days following the date of such casualty, or (B) 270 

American Assets Trust – Lease Form 1/31/2023

 25

 
 
 
 
 
days  after  obtaining  all  required  permits  for  such  reconstruction,  in  which  to  complete  such  work,  (2)  such  destruction  (which  is  not  de 
minimus in nature) occurs during the last year of the Term, or (3) then-existing Laws do not permit such restoration.   Additionally, Landlord 
may, at its election, terminate this Lease by so notifying Tenant in writing on or before the later of 60 days after such destruction or 30 days 
after Landlord's receipt of the proceeds (or written notice of the amount of proceeds) from insurance maintained by Landlord, if (l) such 
destruction  exceeds  20%  of  the  then‑replacement  value  of  the  Premises,  the  Building,  or  the  Project,  or  (ll)  Landlord  reasonably 
determines that the cost of such restoration will exceed the amount of insurance proceeds relating to such destruction actually received by 
Landlord  from  insurance  maintained  by  Landlord,  excluding  deductibles,  by  more  than  5%  of  such  cost  of  restoration.    If  Landlord  or 
Tenant so terminates this Lease, then (x) Landlord shall have no obligation to restore the Project , (y) Landlord shall retain all insurance 
proceeds relating to such destruction, and (z) this Lease shall terminate as of 30 days after such notice of termination from Landlord to 
Tenant.  Tenant hereby waives the provisions of California Civil Code Sections 1932(2) and 1933(4) or any successor statute with respect 
to any destruction of the Premises.  If Landlord restores the Premises following any such destruction, Tenant shall immediately refixturize, 
re-equip,  and  (if  applicable)  restock  the  Premises  and  shall  re-open  the  Premises  for  business  as  soon  thereafter  as  is  reasonably 
practicable, not to exceed 60 days.   If Tenant does not intend to so reopen the Premises for business, it must notify Landlord in writing 
within  20  business  days  of  such  damage  or  destruction,  whereupon  Landlord  may  cease  its  repair  work  and  terminate  this  Lease.  
Additionally, if Landlord fails to Substantially Complete such restoration work within one year, Tenant may, by giving 30 days’ written notice 
to Landlord delivered after such year (during which period of time such restoration is not Substantially Completed), terminate this Lease.

30.Condemnation.    If  during  the  Term,  or  during  the  period  of  time  between  the  execution  of  this  Lease  and  the  Lease 
Commencement  Date,  there  is  any  taking  of  all  or  any  part  of  the  Premises  or  any  interest  in  this  Lease  by  the  exercise  of  any 
governmental  power,  whether  by  legal  proceedings  or  otherwise,  by  any  public  or  quasi‑public  authority,  or  private  corporation  or 
individual,  having  the  power  of  condemnation  (any  of  the  preceding  a  “Condemnor”),  or  a  voluntary  sale  or  transfer  by  Landlord  to  any
Condemnor,  either  under  threat  of  condemnation  or  while  legal  proceedings  for  condemnation  are  pending  (any  of  the  preceding,  a 
“Condemnation”),  the  rights  and  obligations  of  Landlord  and  Tenant  shall  be  determined  pursuant  to  this  Paragraph  30.    If  such 
Condemnation is of the entire Premises, then this Lease shall terminate on the date the Condemnor takes possession of the Premises (the 
“Date  of  Condemnation”).    If  such  Condemnation  is  of  any  portion,  but  not  all,  of  the  Premises,  then  this  Lease  shall  remain  in  effect, 
except that, if the remaining portion of the Premises is rendered unsuitable for Tenant's continued use of the Premises, then Tenant may 
elect to terminate this Lease, by so notifying Landlord in writing (the “Termination Notice”) within 30 days after the date that the nature and 
extent of the Condemnation have been determined.  Such termination shall be effective on the earlier of (i) the date that is 30 days after 
the  delivery  of  the  Termination  Notice,  or  (ii)  the  Date  of  Condemnation.    If  Tenant  does  not  deliver  the  Termination  Notice  to  Landlord 
within  such  30‑day  period,  then  all  obligations  of  Tenant  under  this  Lease  shall  remain  in  full  force  and  effect,  except  that  (unless  the 
Premises  are  restored  as  set  forth  below)  Basic  Monthly  Rent  shall  be  reduced  by  the  ratio  of  (a)  the  Rentable  Square  Footage  of  the 
Premises taken by the Condemnation to (b) the Rentable Square Footage of the Premises immediately prior to the Date of Condemnation.  
Notwithstanding anything to the contrary in this Paragraph, if, within 30 days after Landlord's receipt of the Termination Notice, Landlord 
notifies Tenant that Landlord at its cost will add to the remaining Premises (or substitute for the Premises other comparable space in the 
Project)  so that the Rentable Square Footage of the Premises will be substantially the same after the Condemnation as they were before 
the Condemnation, and Landlord commences the restoration promptly and completes it within 150 days after Landlord so notifies Tenant, 
then all obligations of Tenant under this Lease shall remain in effect, except that Basic Monthly Rent and Additional Rent shall be abated 
or  reduced  during  the  period  from  the  Date  of  Condemnation  until  the  completion  of  such  restoration  by  the  ratio  of  (A)  the  Rentable 
Square Footage of the Premises taken by the Condemnation to (B) the Rentable Square Footage of the Premises immediately prior to the 
Date of Condemnation.  Unless Landlord restores the Premises pursuant to the preceding sentence, or unless Tenant gives to Landlord 
the Termination Notice within the relevant 30‑day period, Tenant at its sole cost and expense shall accomplish any restoration required by 
Tenant to use the Premises.  A temporary Condemnation of the Premises, or any part of the Premises, for less than 180 days, shall not 
constitute a Condemnation under this Paragraph; but the Basic Monthly Rent shall abate as to the portion of the Premises affected during 
such temporary Condemnation.  All compensation, sums, or anything of value awarded, paid, or received as a result of a total or partial 
Condemnation  (the  “Award”)  shall  belong  to  and  be  paid  to  Landlord.    Tenant  shall  have  no  right  to  any  part  of  the  Award,  and  Tenant 
hereby assigns to Landlord all of Tenant's right, title, and interest in and to any part of the Award, except that Tenant shall receive from the 
Award any sum paid expressly to Tenant from the Condemnor for Tenant’s Personal Property or for severance damages.  Landlord and 
Tenant  waive  the  provisions  of  any  statute  (including  without  limitation  California  Code  of  Civil  Procedure  Section  1265.130  or  any 
successor statute) that 

American Assets Trust – Lease Form 1/31/2023

 26

 
 
 
allows Landlord or Tenant to petition the superior court (or any other court) to terminate this Lease in the event of a partial Condemnation 
of the Premises.

31.Assignment and Other Transfers.

31.1. Restriction  on  Transfer.    Without  Landlord’s  prior  written  consent,  which  shall  not  be  unreasonably  withheld  or 
delayed,  and  except  as  permitted  by  Paragraph  31.3,  below,  none  of  the  following  shall  occur  (nor  be  permitted  by  Tenant  to  occur), 
voluntarily, involuntarily, by operation of Laws, or otherwise (any of the following, a “Transfer”): (i) any assignment, sublease, disposition, 
sale, concession, license, license agreement for the use of any portion of the Premises, mortgage, encumbrance, hypothecation, pledge, 
collateral assignment, or other transfer, by Tenant of this Lease, any interest in this Lease, or all or any portion of the Premises; or (ii) any 
assignment, disposition, sale, transfer, acquisition, or issuance of equitable interests (whether stock, partnership or otherwise) in Tenant, to 
or  by  any  person,  entity,  or  group  of  related  persons  or  affiliated  entities,  whether  in  a  single  transaction  or  in  a  series  of  related  or 
unrelated transactions, which results in such person, entity, or group holding (or assigning, transferring, disposing of, or selling) 50% or 
more of the aggregate issued and outstanding equitable interests in Tenant. 

31.2. Transfer Provisions Generally.

31.2.1.  Landlord shall not be liable in damages to Tenant or to any proposed subtenant, assignee or other transferee  
(any of the preceding, a “Proposed Transferee”) if such consent is adjudicated to have been unreasonably withheld, and, in such event, 
Tenant's sole remedy shall be to have the proposed Transfer declared as valid as if Landlord's consent had been given, although Tenant 
shall be entitled to reasonable attorney's fees if Tenant is the prevailing party in such litigation.  At least 30 days prior to entering into any 
proposed  Transfer,  Tenant  shall  submit  to  Landlord  the  non-refundable  sum  of  $2,000  (as  payment  toward  Landlord's  and  Landlord's 
attorneys' cost of reviewing, consenting to, rejecting and/or consummating any proposed Transfer), and a written notice (“Tenant's Notice”) 
which includes (i) a draft copy of the proposed instrument of transfer (i.e., the sublease or assignment instrument) relating to the proposed 
Transfer, along with all related agreements, documents, instruments, exhibits, and escrow instructions, (ii) the name and address of the 
Proposed Transferee, (iii) an abstract of the terms and conditions of the proposed Transfer, including without limitation the economics of 
such Proposed Transfer and the commencement or effective date of the proposed Transfer, which shall be at least 30 days after Tenant's
Notice is given, and (iv) the nature, character, and current banking, financial, and other credit information and references with respect to 
the Proposed Transferee and the business of the Proposed Transferee (including without limitation tax returns for the three most‑recent 
years,  a  business  plan  with  cash‑flow  projections  and  financial  projections  with  assumptions  and  competitive  market  analysis),  in 
reasonably sufficient detail to enable Landlord to determine the Proposed Transferee's financial responsibility.  

31.2.2. Within 30 days after Landlord's receipt from Tenant of such sum and Tenant's Notice, and all documentation  
requested of Tenant by Landlord, Landlord shall notify Tenant whether Landlord has consented to the proposed Transfer.  Any consent by 
Landlord to any proposed Transfer shall not constitute a consent with respect to any other Transfer.  If Landlord consents to any proposed 
Transfer, and Tenant fails to consummate such Transfer within 30 days of the commencement or effective date of the proposed Transfer 
(as set forth in Tenant's Notice) or, if Tenant’s Notice fails to identify such a date, then within 150 days after the date of Tenant’s Notice, 
such  consent  shall  be  deemed  withdrawn  and  Tenant  shall  be  required  again  to  comply  with  this  Paragraph  31.2.2  before  making  a 
Transfer.  Landlord shall not have unreasonably withheld its consent with respect to any Transfer if (among other things) Landlord shall not 
have received such sum or Tenant's Notice, if the nature or character of the Proposed Transferee is not in keeping with the dignity and 
character of the Building and the surrounding area, if the Proposed Transferee’s proposed use is materially and adversely different than 
the Permitted Use or Tenant’s prior use, if the proposed Transfer will result in the diminution of the value or marketability of the Building or 
the Project, if Landlord is not reasonably satisfied that the Proposed Transferee is creditworthy, or if the proposed Transfer will conflict with 
or result in a breach of any of the provisions of, or constitute a default under, any agreement, instrument, or document to which Landlord is 
a party or by which the Project may be bound.  No Transfer shall release or discharge Tenant from any liability, whether past, present, or 
future,  under  this  Lease  and  Tenant  shall  continue  to  remain  directly  and  primarily  liable  under  this  Lease  (and  not  as  a  mere  surety); 
provided,  however,  that  as  a  condition  to  granting  consent  to  any  Transfer,  Landlord  may  require  the  assigning  Tenant  to  execute  a 
guaranty  on  Landlord's  standard  form—which  guaranty  shall  serve  to  release  such  assigning  Tenant  from  direct  liability  hereunder  and 
such  assigning  Tenant’s  liability  for  matters  accruing  under  this  Lease  thereafter  shall  be  pursuant  to  such  guaranty  and  not  under  the 
Lease,  but  Tenant  shall  continue  to  be  liable  for  any  claims  and  liability  accrued  prior  to  such  Transfer  (it  being  understood  that  if  such 
assigning Tenant fails to 

American Assets Trust – Lease Form 1/31/2023

 27

 
 
 
 
 
 
 
 
 
 
 
execute such guaranty, the such assignment shall constitute an Event of Default, such Transfer will be void, and such assigning Tenant 
shall remain primarily liable hereunder).  Tenant irrevocably assigns to Landlord, as security for Tenant's obligations under this Lease, all 
rent and other amounts generated from any Transfer, and Landlord, as assignee and as special attorney‑in‑fact for Tenant, or a receiver 
for Tenant appointed on Landlord's application, may collect such rent and other amounts and apply them toward Tenant's obligations under 
this Lease; provided, however, that unless an Event of Default occurs under this Lease, Tenant shall have the right to collect such rent and 
other  amounts.    Nothing  stated  in  this  Paragraph  31  shall  be  construed  as  extending  to  any  Proposed  Transferee  any  third  party 
beneficiary rights to this Lease or the Premises.

31.2.3   Unless otherwise agreed to by all parties, the Tenant's Security Deposit (if any) shall be retained by Landlord  
and returned to the lawful tenant in possession of the Premises at the time of the Lease termination, subject to the terms and conditions of 
Paragraph 6 of this Lease.  Any Transfer documentation shall contain the following provisions, which provisions whether contained in such 
Transfer  documentation  or  not,  shall  apply  to  such  Transfer:    (a)  such  Transfer  shall  be  subject  and  subordinate  to,  and  bound  by,    all 
provisions of this Lease; (b) no Proposed Transferee shall be permitted to enter into any Transfer without Landlord's prior written consent; 
and (c) at Landlord's option, in the event of cancellation or termination of this Lease for any reason or the surrender of this Lease, whether 
voluntarily, involuntarily, by operation of Laws or otherwise, prior to the expiration of such Transfer, the Proposed Transferee shall make full 
and complete attornment to Landlord for the balance of the term of such Transfer.  Such attornment shall be evidenced by an agreement in 
form and substance reasonably satisfactory to Landlord that the Proposed Transferee shall execute and deliver to Landlord within 5 days 
after request by Landlord.  

31.2.4.   Tenant shall promptly reimburse Landlord for Landlord's reasonable cost (less the $2,000 previously paid) of  
reviewing, consenting to, rejecting and/or consummating any proposed Transfer, including without limitation reasonable attorneys' fees and 
costs and fees of Landlord’s Lender (if any) in connection therewith, not to exceed $2,500 in the aggregate per request.   If Tenant fails to 
pay such amount within 10 business days of written demand, Tenant shall be in default hereunder and Landlord shall have the right, in 
addition  to  its  other  rights  and  remedies  under  this  Lease,  to  revoke  its  prior  approval  of  the  proposed  Transfer  if  such  Proposed 
Transferee has not yet taken possession of the Premises.  

31.3. Excess Rent and Recapture.  Tenant shall promptly pay to Landlord, as and when received, 50% of all rents and 
other  consideration  after  all  of  Tenant’s  reasonable  third-party  expenses  incurred  in  connection  with  such  Transfer  are  deducted,  of 
whatever nature, payable by the Proposed Transferee (or receivable by Tenant) pursuant to or as a result of any Transfer, which exceed (i) 
in the case of a sublease of a portion of the Premises, the portion of the Basic Monthly Rent that is allocable to the portion of the Premises 
subleased (such allocation based on the Rentable Square Footage of the portion subleased), or (ii) in the case of any other Transfer, the 
Basic Monthly Rent.  Landlord additionally has the right, in the event Tenant indicates in the Tenant’s Notice that it desires to assign this 
Lease or sublet greater than 50% of the Premises, at its election, by giving written notice (the “Recapture Notice”) to Tenant within 15 days 
after receipt of Tenant’s Notice, to recapture the Premises and terminate this Lease.  If Landlord elects to exercise such right and delivers 
a Recapture Notice to Tenant, this Lease shall automatically be deemed terminated as of the commencement or effective date stated in 
Tenant’s Notice for the proposed Transfer, and Tenant shall surrender possession of the Premises as of such date (and any failure to do so 
shall constitute a default hereunder).  Landlord’s giving of a Recapture Notice shall not constitute Landlord’s consent to Tenant’s proposed 
Transfer.  Notwithstanding  the  foregoing,  if  Landlord  gives  its  Recapture  Notice,  Tenant  may  within  three  (3)  business  thereafter,  give 
written notice to Landlord of its retraction of Tenant’s Notice, and upon Landlord’s receipt of the same, Landlord shall not have a right to 
recapture the Premises pursuant to this Section.

31.4. Permitted Transferee.  Notwithstanding anything to the contrary contained in Paragraphs 31.1 or 31.3, above, no 
consent of Landlord will be required for, and no amounts will be payable to Landlord in connection with, any assignment or subletting to 
any of the following (any of which will constitute a “Permitted Transferee”):

31.4.1.Any parent, wholly-owned subsidiary, or other company of which Tenant owns all or substantially all of 
the voting and beneficial interests, or which company owns all or substantially all of the voting and beneficial interests in Tenant, and which 
parent, subsidiary, or other company has a tangible net worth (excluding good will as an asset) (determined in accordance with GAAP) 
equal to or greater than Two Hundred Fifty Million Dollars ($250,000,000); or

31.4.2.Any  surviving  or  successor  entity  resulting  from  a  merger,  consolidation,  or  sale  of  substantially  all  of 
the assets of Tenant, where the tangible net worth (excluding good will as an asset) of the resulting or acquiring company exceeds (as 
determined  in  accordance  with  GAAP),  the  tangible  net  worth  (excluding  good  will  as  an  asset)  of  Two  Hundred  Fifty  Million  Dollars 
($250,000,000).

Notwithstanding the foregoing, and as a condition precedent to the effectiveness of any such Transfer to a Permitted Transferee, 
at  least  ten  (10)  days  prior  to  any  proposed  Transfer  to  a  Permitted  Transferee  (except  in  the  case  of  Paragraph  31.4.2  above  where 
confidentiality restrictions prevent disclosure (in which case Tenant shall promptly notify Landlord when such confidentiality restrictions are 
lifted)), Tenant shall notify Landlord in writing of its intention to undertake such a Transfer and provide Landlord with sufficient information 
to confirm that such entity will in fact be a Permitted Transferee and the assigning Tenant shall execute Landlord's form guaranty—which 
guaranty shall serve to release such assigning Tenant from direct liability hereunder and such assigning Tenant will then have liability for 
matters accruing under this Lease thereafter pursuant to such guaranty and not under the Lease, but Tenant shall continue to be liable for 
any claims and liability accrued prior to such Transfer (it being understood that if such assigning Tenant fails to execute such a guaranty, 
then such assignment shall constitute an Event of Default, such Transfer will be void, and such assigning Tenant shall remain primarily 
liable  hereunder).      Landlord  shall  keep  all  such  information  pertaining  to  a  proposed  Transfer  or  a  Proposed  Transferee  confidential.  
Other than the right to engage in such a Transfer to a Permitted Transferee without Landlord’s consent, all other provisions of Paragraph 
31.2 shall apply to such a Transfer.

31.5. Assignment  by  Landlord.    Landlord  may  transfer  or  assign  its  interest  in  this  Lease,  the  Building  and/or  the 
Premises to any person or entity assuming Landlord's obligations under this Lease without Tenant’s consent.  Upon any such transfer or 
assignment,  Landlord  shall  be  released  from  any  further  obligation  hereunder,  and  Tenant  agrees  to  look  solely  to  such  successor  in 
interest of the Landlord for performance of such obligations.  Any security given by Tenant to secure performance of Tenant's obligations 
hereunder may be assigned and transferred by Landlord to such successor in interest, and Landlord shall thereby be discharged of any 
further obligation relating thereto.

32.Landlord’s Reserved Rights.

32.1. General  Rights  Reserved.    In  addition  to  specific  reserved  rights  identified  elsewhere  in  this  Lease,  below, 
Landlord,  as  owner  of  the  Project,  in  addition  to  Landlord’s  other  rights,  reserves  the  right  from  time  to  time:  (i)  to  temporarily  utilize 
portions of the Common Areas for, among other things, entertainment, outdoor shows, displays, automobile and other product shows, the
leasing  of  kiosks,  or  such  other  uses  which,  in  Landlord’s  sole  discretion,  are  appropriate;  (ii)  to  utilize  the  lighting  standards  and  other 
areas  or  improvements  in  the  Common  Areas  for  advertising,  notice  purposes,  or  other  reasonable  purposes;  (iii)  to  close  any  of  the 
Common Areas to the extent required in the opinion of Landlord's legal counsel to prevent a dedication of any of the Common Areas or the 
accrual  of  any  rights  to  any  person  or  to  the  public  in  and  to  any  portion  of  the  Common  Areas;  (iv)  to  close,  temporarily,  any  of  the 
Common  Areas  for  maintenance  purposes;  (v)  to  designate  other  property  outside  the  boundaries  of  the  Project  to  become  part  of  the 
Common Areas; (vi) to close off or otherwise utilize portions of the Common Areas while constructing improvements or making repairs or 
alterations  to  any  portion  of  the  Project;  (vii)  to  utilize  portions  of  the  Common  Areas,  on  a  temporary  basis,  as  a  staging  area  for  any 
construction work by Landlord or its affiliates, agents, tenants, or contractors; and (viii) to make any changes to the Common Areas, or any 
part  of  the  Project,  including  without  limitation  changes  to  buildings  or  other  improvements,  the  addition  of  new  buildings  or  other 
improvements,  and/or  changes  in  (among  other  things)  the  location  of  driveways,  entrances,  exits,  vehicular  parking  spaces,  or  the 
direction  of  the  flow  of  traffic.    In  exercising  such  rights,  Landlord  agrees  to  use  commercially  reasonable  efforts  to  minimize  any 
interference with Tenant’s use of the Premises.

32.2. Future  Construction.    Tenant  acknowledges  that,  as  more  particularly  provided  below,  the  development  of  the 
Project is continuing and may, at Landlord’s election, include the construction of additional buildings and improvements within the Project, 
including in areas which currently constitute Common Areas.  Tenant is entering into this Lease with a full understanding of the possible 
ramifications/effects  of  such  future  development  work  on  its  tenancy  and  the  rental  charged  hereunder  takes  such  factors  into  account.  
Tenant further acknowledges and agrees that Landlord may, from time to time, at its sole election, construct (including, without limitation, 
additional buildings), reconstruct (including without limitation the replacement of certain improvements with other improvements), improve 
(including  tenant  improvements),  modify,  expand,  or  otherwise  alter  the  Project  or  portions  thereof,  including  a  remodel,  renovation,  or 
refurbishment of the Premises (collectively, “Construction Work”) (in no event however will Landlord have any obligation to do so).  Tenant 
acknowledges that any such Construction Work 

American Assets Trust – Lease Form 1/31/2023

 29

 
 
 
 
 
 
 
 
will  necessarily  involve,  among  other  things,  the  generation  of  noise,  dust,  and  vibrations,  barricading  portions  of  the  Project  and  the 
placement of scaffolding within the Project, demolition, structural alterations, storage of materials and equipment within the Project, and 
the  presence  of  workmen  within  the  Project,  all  of  which  may  require  the  rearrangement  of  the  Common  Areas,  including,  without 
limitation,  landscaping,  parking  areas  (which  may  include  the  provision  of  temporary  parking  areas  during  periods  of  construction), 
roadways,  lighting  facilities,  and  the  re-direction  of  vehicular  and  pedestrian  traffic.    Tenant  agrees  that  the  performance  of  any 
Construction  Work  shall  not  constitute  an  eviction  (constructive  or  otherwise);  provided,  however,  Landlord  agrees  to  use  commercially 
reasonable  efforts  to  minimize  any  interference  with  Tenant’s  use  of  the  Premises  in  connection  with  such  Construction  Work.  Further, 
Landlord  hereby  reserves  such  licenses  and  easements  in,  on,  above  or  below  the  Premises  as  may  be  reasonably  required  (i)  for  the 
installation, inspection, surveying, maintenance, or construction of mains, conduits, shafts, columns, footings, piers, pipes or other facilities 
to serve any building within the Project, or (ii) for any Construction Work; provided, however, Landlord will use its commercially reasonable 
efforts  to  minimize  any  unreasonable  interference  with  Tenant’s  use,  occupancy,  or  enjoyment  of  the  Premises  as  contemplated  by  this 
Lease.    Except  as  provided  below,  Tenant  waives  any  and  all  claims,  defenses,  rights  of  offset,  or  deductions  based  upon  any 
inconvenience  suffered  by  Tenant  or  any  interruption  of  or  interference  with  Tenant’s  business  including,  without  limitation,  any  loss  of 
business, decreased sales, damage to property, loss of electronic information, or inconvenience to Tenant or Tenant’s Invitees as a result 
of or relating to such Construction Work.   Landlord hereby reserves for itself and its agents, employees, licensees and contractors, the 
right to enter the Premises to the extent reasonably necessary to pursue such Construction Work upon twenty-four (24) hours’ prior notice 
to Tenant.   The exercise of any of Landlord’s rights pursuant to this Paragraph will not entitle Tenant to any abatement of Rent or other 
claim, right of offset, or defense against Landlord, except that (subject to the provisions of Paragraphs 19, 36, 44, and other provisions of 
this Lease) (a) Tenant shall have the right to bring an action against Landlord (as Tenant’s sole remedy) in the event Tenant suffers any 
damages as a result of Landlord’s negligence or intentional misconduct in pursuing such Construction Work, and (b) if such Construction 
Work  results  in  Tenant  being  unable  to  access  the  Premises,  or  portions  thereof,  for  the  Permitted  Use  for  a  period  of  greater  than  5 
business days, Tenant shall be entitled (as Tenant’s sole remedy with respect to such lack of access) to equitable abatement of the Rent 
for such period of time during which it is unable to access the Premises.   The foregoing rights will constitute Tenant’s sole and absolute 
rights  against  Landlord  or  otherwise  in  connection  with  any  such  Construction  Work  and  Tenant  releases  and  waives  any  other  claims, 
defenses,  or  rights  in  connection  therewith.    Tenant  further  acknowledges  that  expansion  of  the  Project  may  affect  the  amount  of  the 
Operating Expenses and the portion thereof payable by Tenant.

32.3. Relocation. Intentionally deleted.   

33.Easements.    Landlord  may,  at  its  election,  from  time  to  time,  grant  such  easements,  rights  and  dedications,  and  cause  the 
recordation of parcel maps, easement and operating agreements, and restrictions affecting the Premises and the Project, provided that no 
such acts materially and adversely affect Tenant’s rights of ingress or egress to the Building and the Premises or Tenant’s right to use the 
Premises.  Tenant shall promptly sign any commercially reasonable documents or instruments to accomplish the foregoing upon request 
by  Landlord.    Tenant  irrevocably  appoints  Landlord  as  Tenant’s  special  attorney-in-fact  to  execute  and  deliver  such  documents  or 
instruments on behalf of Tenant if Tenant refuses or fails to do so within 10 days after Landlord’s written request.

34.Access  by  Landlord.    Landlord  and  any  of  Landlord's  Invitees  shall  have  the  right  to  enter  the  Premises  at  all  reasonable 
times, during normal business hours if feasible under the circumstances, and upon 24 hours’ notice, if feasible under the circumstances, (i) 
to determine whether the Premises are in good condition and whether Tenant is complying with its obligations under this Lease, (ii) to do 
any  necessary  maintenance  or  make  any  restoration  to  the  Premises  that  Landlord  has  the  right  or  obligation  to  perform,  (iii)  to  serve, 
post, or keep posted any notices required or allowed under this Lease, (v) to post “for sale” or “for rent” or “for lease” signs during the final 
nine months of the Term, (vi) to show the Premises to brokers, lenders, agents, prospective buyers, prospective tenants, or other persons 
interested in a listing of, financing, purchasing, or occupying the Project, the Premises or any portion of the Project or the Premises, and 
(vii) to shore the foundations, footings, and walls of the Project, and to erect scaffolding and protective barricades around and about the 
Premises, but not so as to prevent entry to the Premises, and to do any other act or thing necessary for the safety or preservation of the 
Premises if any excavation or other construction is undertaken or is about to be undertaken on any adjacent property or nearby street.  In 
the event of an emergency Landlord shall have the right to enter the Premises at any time, without prior notice to Tenant.  Landlord's rights 
under  this  Paragraph  extend,  with  Landlord's  consent,  to  the  owner  of  adjacent  property  on  which  excavation  or  construction  is  to  take 
place and the adjacent property owner's agents, employees, officers, and

contractors.  Landlord shall not be liable for any inconvenience, disturbance, loss of business, nuisance, or other damage arising out of 
any entry on the Premises as provided in this Paragraph except damage resulting directly from the negligent acts or willful misconduct of 
Landlord or Landlord's Invitees.  Tenant shall not be entitled to any abatement or reduction of Basic Monthly Rent or other Rent because of 
the exercise by Landlord of any rights under this Paragraph.

35.Indemnity.    Tenant  hereby  agrees  to  indemnify,  defend,  protect,  and  hold  harmless  Landlord  and  its  shareholders,  officers, 
directors, agents, property managers, employees, contractors, and the partners comprising Landlord (if any) from and against any and all 
liabilities,  damages,  losses,  costs,  expenses,  attorneys'  fees,  and  claims,  including,  without  limitation,  any  and  all  costs,  expenses,  and 
attorneys’  fees  incurred  in  the  defense  or  handling  of  any  such  claims  and/or  any  action  or  proceeding  brought  on  any  of  such  claims 
(collectively, “Claims”) (except to the extent they result from Landlord's negligent acts or willful misconduct) to the extent arising from or 
which  seek  to  impose  liability  under  or  because  of  (i)  Tenant's  or  Tenant's  Invitees'  use  of  the  Premises,  (ii)  the  conduct  of  Tenant's 
business, (iii) any activity, work, or things done, permitted, or suffered by Tenant or any of Tenant's Invitees in or about the Premises or 
elsewhere,  (iv)  any  breach  or  default  in  the  performance  of  any  obligation  to  be  performed  by  Tenant  under  this  Lease,  and/or  (v)  any 
negligence  of  Tenant  or  any  of  Tenant's  Invitees.    If  any  action  or  proceeding  is  brought  against  Landlord  or  its  shareholders,  officers, 
directors, agents, property managers, employees, contractors, or the partners comprising Landlord (if any) by reason of any such Claims, 
Tenant upon notice from Landlord shall defend such action or proceeding at Tenant's sole cost and expense by legal counsel satisfactory 
to Landlord. 

36.Exemption of Landlord from Liability.  Except to the extent caused by Landlord's negligent acts or willful misconduct, Tenant 
assumes all risk of, Tenant waives all claims against Landlord in respect of, and Landlord shall not be liable for, any of the matters set forth 
in the preceding Paragraph or any of the following: injury to Tenant's business, loss of income from such business, or damage or injury to 
the goods, wares, merchandise, or other property or the person of Tenant, Tenant's Invitees, or any other persons in, upon, or about the 
Premises,  whether  such  damage,  loss,  or  injury  is  caused  by  or  results  from  criminal  acts,  fire,  steam,  electricity,  gas,  water,  rain,  the 
breakage, leakage, obstruction or other defects of pipes, sewer lines, sprinklers, wires, appliances, plumbing, air‑conditioning or lighting 
fixtures, or any other cause, conditions arising upon the Premises, or other sources or places, and regardless of whether the cause of such 
damage, loss, or injury or the means of repairing such damage, loss, or injury is inaccessible to Tenant. In connection with the foregoing, 
Tenant hereby waives any defense that would otherwise be provided by Section 1542 of the California Civil Code (which states "A general 
release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of 
executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released 
party"), or Laws of a similar nature, which would limit any such release to matters known or suspected to exist by Tenant. This Lease shall 
not be affected or impaired by any change to any part of the Project or any sidewalks, streets or improvements nearby the Project.  

37.Hazardous Substances.

37.1. Landlord’s  Covenants.    Landlord  hereby  notifies  Tenant,  and  Tenant  hereby  acknowledges  that,  prior  to  the 
leasing of the Premises pursuant to this Lease, Tenant has been notified, pursuant to California Health and Safety Code Section 25359.7, 
that  Landlord  knows,  or  has  reasonable  cause  to  believe,  that  certain  hazardous  substances  (as  such  term  is  used  in  such  Section 
25359.7),  such  as  common  cleaning  supplies,  office  supplies,  spillage  of  petroleum  products  from  motor  vehicles,  and  other  consumer 
products, may be located (now or in the future) on or beneath the Premises and/or the Project.  Notwithstanding the foregoing, Landlord 
shall not cause any unlawful accumulations of Hazardous Materials to be generated, brought onto, used, stored, or disposed of in or about 
the Premises, the Building, or the Project by Landlord or its agents, employees, or contractors, except for limited quantities of standard 
office and janitorial supplies and petroleum and petroleum-related products commonly used on or at similar office projects.  Furthermore, 
Landlord  shall:  (a)  use,  store,  and  dispose  of  all  such  permitted  Hazardous  Material  in  strict  compliance  with  all  applicable  statutes, 
ordinances,  and  regulations  in  effect  during  the  Term  that  govern  and/or  relate  to  Hazardous  Material,  public  health  and  safety  and 
protection  of  the  environment,  and  (b)  comply  at  all  times  during  the  Term  with  all  Environmental  Laws  (as  defined  in  Paragraph  37.2, 
below).  Except as to those matters which are Tenant’s responsibility pursuant to Paragraph 37.2, below, Landlord shall be responsible, at 
its expense (or the expense of others; but not as an Operating Expense) to cause any unlawful accumulations of Hazardous Materials to 
be remediated in accordance with the requirements of all applicable Environmental Laws.

Building, and the Project will be in full compliance with

Landlord’s  negligent  acts  or  willful  misconduct),  arising  from  or  relating  to:  (i)  any  discharges,  releases,  or  threatened  releases  of  any 
Hazardous  Materials  into  ambient  air,  water,  or  land  by  Tenant  or  Tenant’s  Invitee’s  from,  on,  under,  or  above  the  Premises,  (ii)  the 
manufacture, processing, distribution, use, treatment, storage, disposal, transport, or handling of pollutants, contaminants, or hazardous or 
toxic wastes, substances, or materials by Tenant or Tenant’s Invitees, or otherwise from, on, or under, the Premises, or (iii) a violation by 
Tenant  of  any  Environmental  Law  on,  under,  or  above  the  Premises  (for  purposes  of  this  Lease,  “Environmental Laws”  shall  mean  any 
Federal, State, or local Laws, statute, regulation, ordinance, guideline, or common Laws principle relating to public health or safety or the 
use or control of the environment, including without limitation the Federal Comprehensive Environmental Response, Compensation and

Act,  the  Federal  Resource  Conservation  and  Recovery  Act,  the  California  Nejedly‑Z'berg‑Dills  Solid  Waste  Management  and  Recovery 
Act,  and  California  Health  and  Safety  Code  Section  25359.7)  and  any  other  Laws  governing  environmental  or  Hazardous  Materials 
matters in California.  Tenant shall not cause or permit any Hazardous Materials to be generated, brought onto, used, stored, or disposed 
of in or about the Premises, the Building, or the Project by Tenant or its agents, employees, contractors, subtenants, or invitees, except for 
limited  quantities  of  standard  office  and  janitorial  supplies.    Tenant  shall:    (a)  use,  store,  and  dispose  of  all  such  permitted  Hazardous 
Materials in strict compliance with all applicable statutes, ordinances, and regulations in effect during the Term that govern and/or relate to 
Hazardous  Materials,  public  health  and  safety  and  protection  of  the  environment,  and  (b)  comply  at  all  times  during  the  Term  with  all 
Environmental  Laws.    If  the  Premises  are  contaminated  (or,  due  to  the  acts  or  omissions  of  Tenant  or  Tenant's  Invitees,  the  Project  is 
contaminated) by any Hazardous Materials during the Term, then (1) Tenant shall promptly notify Landlord in writing of such contamination, 
and (2) Landlord may elect to either (A) demand that Tenant perform all remediation required by Landlord (to Landlord's satisfaction and at 
Tenant's sole cost and expense, necessary to return the Premises (and/or the Project) to at least as good a condition as the Premises (or 
the Project) are in as of the date of this Lease, which Tenant shall immediately do upon receipt of notice from Landlord, or (B) proceed to 
cause such investigation, clean-up, and remediation work which Landlord deems necessary or desirable to be undertaken, whereupon the 
entire  cost  thereof  (plus  a  supervisory  fee  equal  to  ten  percent  of  such  cost)  will  be  payable  by  Tenant  to  Landlord  upon  demand  as 
Additional Rent. If, after demand by Landlord, as provided in this Paragraph, Tenant does not promptly commence and diligently pursue 
such  remediation,  then  Landlord  may,  at  Landlord's  election,  perform  or  cause  to  be  performed  such  remediation  and  Tenant  shall 
immediately,  upon  demand,  pay  the  cost  thereof  to  Landlord,  plus  a  supervisory  fee  in  the  amount  of  ten  percent  (10%)  of  such  cost. 
Tenant's obligations and liability under this Paragraph 37.2 shall survive the termination of Tenant's tenancy and the Term of this Lease, 
except that nothing contained in this Paragraph 37.2 shall be deemed to impose liability on Tenant for any contamination arising before or 
after the Term of this Lease provided that neither Tenant nor Tenant's Invitees contributed to such contamination during the Term.  Tenant 
acknowledges that it has reviewed the Guidelines for Avoiding Moisture and Mold Problems in the Premises attached hereto as Exhibit “G” 
(the “Moisture Guidelines”), and agrees to comply with the Moisture Guidelines.

37.3. Definition of Hazardous Materials.  As used in this Lease the term "Hazardous Materials" shall mean any material 
or substance that is (i) defined as a “hazardous waste,” “extremely hazardous waste,” “restricted hazardous waste,” hazardous substance,” 
hazardous material,” “waste,” “pollutant,” “contaminant” or “toxic chemical, material or substance” as any of those terms are defined under 
(a)  the  Comprehensive  Environmental  Response,  Compensation,  and  Liability  Act  of  1980  (CERCLA)  (42  United  States  Code  Sections 
9601-9675); (b) the Resource Conservation and Recovery Act of 1976 (RCRA) (42 United States Code Sections 6901-6992k); or (c) any

38.Prohibition  Against  Mold,  Lead-Based  Paint,  and  Asbestos-Containing  Materials.  Tenant  shall  not  allow  or  permit  any  lead-
based paint to be used in the Premises, nor shall Tenant allow or permit any condition, conduct or omission at the Premises, or anywhere 
on the Project, that will promote or allow the production or growth of mold spores, fungus, or other similar organism within the Premises.  
Additionally,  Tenant  shall  not  allow  or  permit  any  materials  which  contain  asbestos  in  any  form  or  concentration  (“Asbestos-Containing

stored in the Premises or used in the construction of any improvements or alterations to the Premises, including, without limitation, building 
or  construction  materials  and  supplies.    Such  prohibition  against  Asbestos-Containing  Materials  shall  apply  regardless  of  whether  the 
Asbestos-Containing Materials may be considered safe or approved for use by a manufacturer, supplier, or governmental authority, or by 
common use or practice. Landlord shall have the right, upon 24-hours’ notice, to enter upon and conduct inspections of the Premises to 
determine Tenant's compliance with this Paragraph 38. If Tenant violates the foregoing covenants relating to lead-based paint, mold, and 
Asbestos-Containing  Materials  (collectively  “Prohibited  Substances”),  then  (a)  Tenant  shall,  upon  notice  from  Landlord,  immediately 
remove  and  remediate  any  damage  from  such  Prohibited  Substances  at  Tenant's  sole  cost  and  expense,  (b)  such  removal  and 
remediation  shall  comply  with  all  applicable  Laws,  (c)  Tenant  shall  reimburse  Landlord  for  all  expenses  incurred  in  connection  with  any 
inspection and testing of the Premises conducted by Landlord, and (d) unless Tenant completes such removal within 30 days after notice 
from Landlord, Landlord may, at its election, do either or both of the following: (i) declare an Event of Default under Paragraph 24.4 (for 
which no notice by Landlord is required) and exercise Landlord’s remedies hereunder, including, without limitation, terminate this Lease 
upon 10 days prior written notice to Tenant, and/or (ii) remove and remediate such Prohibited Substances and obtain reimbursement from 
Tenant for the cost of such removal and remediation, including a supervisory fee payable to Landlord in the amount of ten percent (10%) of 
the  removal  and  disposal  cost.  Tenant  shall  indemnify  Landlord  and  Landlord's  directors,  officers,  employees,  and  agents  against  all 
Claims  arising  from  (A)  the  failure  to  strictly  comply  with  the  obligations  under  this  provision  as  evidenced  by  the  presence  of  any 
Prohibited Substances upon the Premises (B) any lawsuit, settlement, governmental order, or decree relating to the presence, handling, 
removal, or disposal of Prohibited Substances upon or from the Premises, to the extent that such  Prohibited Substances are used, stored, 
or  otherwise  permitted  in  the  Premises  or  used  in  the  construction  of  any  improvements  or  Alterations  to  the  Premises  by  Tenant  or 
Tenant's agents, employees, representatives or independent contractors, or (C) Tenant's failure to perform its obligations to remove such 
Prohibited Substances under this Paragraph 38.  The provisions of this Paragraph 38 shall not apply to any Prohibited Substances brought 
onto the Premises by Landlord or Landlord’s Invitees or resulting from the acts of Landlord or Landlord’s Invitees.

39.Security  Measures.    Tenant  acknowledges  that,  although  the  Building  may  contain  a  restricted  access  entry  system  (if 
provided for as part of Landlord's Work), (i) the Basic Monthly Rent does not include the cost of any security measures for any portion of 
the  Project  (ii)    Landlord  shall  have  no  obligation  to  provide  any  such  security  measures,  (iii)    Landlord  has  made  no  representation  to 
Tenant  regarding  the  safety  or  security  of  the  Project,  and  (iv)  Tenant  will  be  solely  responsible  for  providing  any  security  it  deems 
necessary to protect itself, its property, and Tenant's Invitees in, on, or about the Project.  If Landlord provides any security measures at 
any time, then the cost thereof shall be included as part of the Operating Expenses, but Landlord will not be obligated to continue providing 
such  security  measures  for  any  period  of  time,  Landlord  may  discontinue  such  security  measures  without  notice  and  without  liability  to 
Tenant,  and  Landlord  will  not  be  obligated  to  provide  such  security  measures  with  any  particular  standard  of  care.    Tenant  assumes  all 
responsibility  for  the  security  and  safety  of  Tenant,  Tenant's  property,  and  Tenant's  Invitees.    Tenant  releases  Landlord  from  all  claims 
whatsoever  (other  than  due  to  Landlord's  negligence  or  intentional  misconduct)  for  damage,  loss,  or  injury  to  Tenant,  Tenant's  Invitees, 
and/or to the personal property of Tenant and/or of Tenant's Invitees, even if such damage, loss, or injury is caused by or results from the 
criminal, reckless, or negligent acts of third parties. In connection with the foregoing, Tenant hereby waives any defense would otherwise 
be provided by Section 1542 of the California Civil Code (which states "A general release does not extend to claims that the creditor or 
releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, 
would have materially affected his or her settlement with the debtor or released party"), or Laws of a similar nature, which would limit any 
such release to matters known or suspected to exist by Tenant. Tenant is hereby instructed to conduct its own investigation through local 
police agencies regarding any criminal acts or dangerous conduct that has occurred in or near the Project.  Landlord shall have no duty to 
warn  Tenant  of  any  criminal  acts  or  dangerous  conduct  that  has  occurred  in  or  near  the  Project,  regardless  of  Landlord's  knowledge  of 
such crimes or conduct, and Tenant hereby undertakes to remain informed regarding such issues.

40.Subordination and Attornment.  This Lease and Tenant's rights under this Lease are subject and subordinate to any mortgage, 
deed of trust, ground lease, or underlying lease (and to all renewals, modifications, consolidations, replacements, or extensions thereof), 
now  or  hereafter  affecting  the  Premises;  provided,  however,  that  such  mortgagor,  beneficiary  or  ground  lessor  has  executed  a 
commercially  reasonable  Subordination  and  Non-Disturbance  Agreement  providing  that  the  Lease  and  Tenant  occupancy  shall  not  be 
disturbed so long as Tenant is not in an Event of Default under the Lease.   The provisions of this Paragraph shall be self‑operative, and 
no further instrument of subordination shall be required.  In confirmation of such subordination, however, Tenant shall promptly execute 
and deliver any commercially reasonable

instruments that Landlord, any Lender, or the lessor under any ground or underlying lease, may request to evidence such subordination, 
provided such instrument contains customary non-disturbance language in favor of Tenant and is consistent with the provisions of the next 
sentence  including,  without  limitation,  a  Subordination,  Attornment,  and  Non-Disturbance  Agreement  in  the  form  to  be  commercially 
reasonable and acceptable to Lender. If any Lender, or the lessor of any ground or underlying lease affecting the Premises, shall hereafter 
succeed  to  the  rights  of  Landlord  under  this  Lease,  whether  by  foreclosure,  deed  in  lieu  of  foreclosure,  or  otherwise,  then  (i)  such 
successor landlord shall not be subject to any offsets or defenses which Tenant might have against Landlord, (ii) such successor landlord 
shall not be bound by any prepayment by Tenant of more than one month's installment of Basic Monthly Rent or any other Rent, (iii) such 
successor landlord shall not be subject to any liability or obligation of Landlord except those arising after such succession, (iv) Tenant shall 
attorn  to  and  recognize  such  successor  landlord  as  Tenant's  landlord  under  this  Lease  and  such  successor  shall  not  disturb  Tenant’s 
possession  under  this  Lease,  (v)  Tenant  shall  promptly  execute  and  deliver  any  commercially  reasonable  instruments  that  may  be 
necessary  to  evidence  such  attornment  and  non-disturbance,  (vi)    upon  such  attornment,  this  Lease  shall  continue  in  effect  as  a  direct 
lease (whether separately documented or not) between such successor landlord and Tenant upon and subject to all of the provisions of 
this Lease, and (vii) Tenant shall be entitled to quiet enjoyment of the Premises for so long as Tenant is not in default under the terms of 
this Lease or any substitute lease referenced above.  Notwithstanding the preceding provisions of this Paragraph, if any ground lessor or 
Lender elects to have this Lease prior to the lien of its ground lease, deed of trust, or mortgage, and gives written notice thereof to Tenant 
that this Lease shall be deemed prior to such ground lease, deed of trust, or mortgage, whether this Lease is dated prior or subsequent to 
the date of such ground lease, deed of trust, or mortgage, then this Lease shall be deemed to be prior to the lien of such ground lease or
mortgage and such ground lease, deed of trust, or mortgage shall be deemed to be subordinate to this Lease.  

41.Estoppel  Certificate.    Within  10  days  after  written  request  from  Landlord,  Tenant  shall  execute  and  deliver  to  Landlord  a 
certificate (“Estoppel Certificate”) stating (i) that this Lease is unmodified and in full force and effect, or in full force and effect as modified, 
and stating all modifications, (ii) the then‑current Basic Monthly Rent, (iii) the dates to which Basic Monthly Rent has been paid in advance, 
(iv)  the  amount  of  any  security  deposit  or  letter  of  credit,  if  applicable,  prepaid  rent  or  other  payment  constituting  Rent  which  has  been 
paid, (v) whether or not Tenant or, to the knowledge of Tenant, Landlord is in default under this Lease and whether, to the knowledge of 
Tenant, there currently exist any defenses or rights of offset under the Lease in favor of Tenant, (vi) that any work required to be performed 
by  Landlord  under  this  Lease  is  complete  (or  stating  any  exceptions),  (vii)  that  any  tenant  improvement  allowance  has  been  paid  (or 
stating any exceptions), and (viii) such other matters as Landlord may reasonably request.  Landlord will similarly, in connection with any 
lending or Transfer transaction, upon 10-days written request from Tenant, execute an estoppel certificate in favor of Tenant's proposed 
lender  or  Transferee  confirming  (i)  that  this  Lease  is  unmodified  and  in  full  force  and  effect,  or  in  full  force  and  effect  as  modified,  and 
stating all modifications, (ii) the then‑current Basic Monthly Rent, (iii) the dates to which Basic Monthly Rent has been paid in advance, (iv) 
the amount of any security deposit or letter of credit, if applicable, prepaid rent, or other payment constituting Rent which has been paid, 
and (v) whether or not to the best of Landlord's knowledge Tenant is in default under this Lease.  The requirement for Tenant to execute
and  deliver  to  Landlord,  the  Estoppel  Certificate,  as  required  above,  shall  not  be  delayed,  conditioned,  or  withheld  for  any  reason;  this 
requirement shall be an independent covenant of Tenant under this Lease. 

42.Waiver.  No delay or omission in the exercise of any right or remedy of Landlord in the event of any default or Event of Default 
by Tenant shall impair such right or remedy or be construed as a waiver.  The receipt and acceptance by Landlord of delinquent Rent shall 
not constitute a waiver of any default other than the particular Rent payment accepted.  Landlord's receipt and acceptance from Tenant, on 
any date (the “Receipt Date”), of an amount less than  the Rent actually due on such Receipt Date, or to become due at a later date but 
applicable to a period prior to such Receipt Date, shall not release Tenant of its obligation (i) to pay the full amount of such Rent due on 
such Receipt Date or (ii) to pay when due the full amount of such Rent to become due at a later date but applicable to a period prior to 
such Receipt Date.  No act or conduct of Landlord, including without limitation, the acceptance of the keys to the Premises, shall constitute 
an acceptance by Landlord of the surrender of the Premises by Tenant before the Expiration Date.  Only a written notice from Landlord to 
Tenant stating Landlord's election to terminate Tenant's right to possession of the Premises shall constitute acceptance of the surrender of 
the  Premises  and  accomplish  a  termination  of  this  Lease.    Landlord's  consent  to  or  approval  of  any  act  by  Tenant  requiring  Landlord's 
consent or approval shall not be deemed to waive or render unnecessary Landlord's consent to or approval of any other or subsequent act 
by Tenant.  Any waiver by Landlord of any default must be in writing and shall not be a waiver of any other default concerning the same or 
any other provision of this Lease.  Tenant hereby waives any rights granted to Tenant under California Code of Civil Procedure Section 
1179, California 

American Assets Trust – Lease Form 1/31/2023

 34

 
 
 
 
Civil Code Section 3275, and/or any successor statute(s).  Tenant represents and warrants that if Tenant breaches this Lease and, as a 
result, this Lease is terminated, Tenant will not suffer any undue hardship as a result of such termination and, during the Term, will make 
such  alternative  or  other  contingency  plans  to  provide  for  its  vacation  of  the  Premises  and  relocation  in  the  event  of  such  termination.  
Tenant acknowledges that Tenant's waivers set forth in this Paragraph are a material part of the consideration for Landlord's entering into 
this Lease and that Landlord would not have entered into this Lease in the absence of such waivers.

43.Brokers.    Tenant  represents  that  no  real  estate  broker,  agent,  finder,  or  other  person  is  responsible  for  bringing  about  or
negotiating this Lease other than the Tenant's broker, if any, listed in the Principal Lease Provisions, and Tenant has not dealt with any 
other  real  estate  broker,  agent,  finder,  or  other  person,  relative  to  this  Lease  in  any  manner.    Tenant  shall  indemnify,  defend,  and  hold 
Landlord  harmless  from  and  against  all  liabilities,  damages,  losses,  costs,  expenses,  attorneys'  fees  and  costs,  and  claims  arising  from
any claims that may be made against Landlord by any real estate broker, agent, finder, or other person (other than as set forth above), 
alleging  to  have  acted  on  behalf  of  or  to  have  dealt  with  Tenant.    Landlord  represents  that  no  real  estate  broker,  agent,  finder,  or  other 
person  is  responsible  for  bringing  about  or  negotiating  this  Lease  other  than  the  Landlord’s  broker,  if  any,  listed  in  the  Principal  Lease 
Provisions,  and  Landlord  has  not  dealt  with  any  other  real  estate  broker,  agent,  finder,  or  other  person,  relative  to  this  Lease  in  any 
manner.  Landlord shall indemnify, defend, and hold Tenant harmless from and against all liabilities, damages, losses, costs, expenses, 
attorneys' fees and costs, and claims arising from any claims that may be made against Tenant by any real estate broker, agent, finder, or 
other  person  (other  than  as  set  forth  above),  alleging  to  have  acted  on  behalf  of  or  to  have  dealt  with  Landlord.    Landlord  shall  be 
responsible, upon satisfaction of the requirements of a separate written listing agreement between Landlord and Landlord's broker, for the 
payment of the commission due and owing to Landlord's brokers identified in the Principal Lease Provisions (or any other brokers engaged 
by  Landlord),  pursuant  to  such  separate  written  agreement  between  Landlord  and  Landlord's  broker.  Landlord's  broker  will  in  turn  split 
such commission with Tenant's broker as such parties may agree.

44.Limitations  on  Landlord's  Liability;  Waiver  of  Consequential  Damages.    If  Landlord  is  in  default  of  this  Lease,  and  as  a 
consequence  Tenant  recovers  a  money  judgment  against  Landlord,  such  judgment  shall  be  satisfied  only  out  of  the  proceeds  of  sale 
received upon execution of such judgment and levy against the right, title, and interest of Landlord in the Project, and out of rent or other 
income from the Project receivable by Landlord or out of the consideration received by Landlord from the sale or other disposition of all or 
any part of Landlord's right, title, and interest in the Project.  Notwithstanding anything contained in this Lease to the contrary, under no 
circumstances  whatsoever  shall  any  Landlord  or  any  of  Landlord's  present  or  future  shareholders,  trustees,  beneficiaries,  participants, 
members, officers, directors, agents, advisors, property managers, employees, contractors, or the partners comprising Landlord (if any) or 
affiliates or any of their heirs, successors or assignees be liable for any incidental, indirect, special, consequential or punitive damages, 
including, without limitation, lost profits, nor shall any of them be personally liable for any deficiency.  

45.Sale or Transfer.  If Landlord sells or transfers the Premises or the Project (whether voluntarily or involuntarily), Landlord, on 
consummation of the sale or transfer and assumption of this Lease by Landlord's successor‑in‑interest, shall be released from any liability 
thereafter accruing under this Lease.  If any Security Deposit or prepaid Rent has been paid by Tenant or if a Letter of Credit has been 
issued pursuant to this Lease, Landlord may transfer the Security Deposit and/or 1 month prepaid Rent or Letter of Credit, if applicable to 
Landlord's  successor‑in‑interest  and  on  such  transfer  Landlord  shall  be  discharged  from  any  further  liability  arising  from  the  Security 
Deposit or such prepaid Rent or Letter of Credit, if applicable.

46.Quitclaim  Deed.    Tenant  shall  execute  and  deliver  to  Landlord  on  the  Expiration  Date,  promptly  on  Landlord's  request,  a

quitclaim deed to the Premises, in recordable form, designating Landlord as transferee, and confirming the termination of the Lease.

47.No Merger.  The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation of this Lease, or a termination 
by  Landlord,  shall  not  work  a  merger,  and  shall,  at  the  option  of  Landlord,  terminate  any  existing  subleases  or  may,  at  the  option  of 
Landlord, operate as an assignment to Landlord of any such subleases.

48.Confidentiality.    Except  as  essential  to  the  consummation  of  the  transaction  contemplated  by  this  Lease  (together  with  all 

amendments and addenda hereto):

damages or an agreed upon sum to be paid by one party to the other for a breach by one of the parties, the parties hereby agree that all 
such amounts so specified are not intended as a forfeiture or penalty but are intended to constitute reasonable liquidated damages to the 
non-breaching  party  because  the  loss  or  harm  resulting  from  the  breach  is  uncertain  or  difficult  to  prove  with  certainty,  and  the  amount 
specified in each such case is reasonable in light of the anticipated or actual damages caused by the breach.

51.11. Covenants  and  Conditions;  Survival.    All  provisions,  whether  covenants  or  conditions,  to  be  performed  or 
observed  by  Tenant  shall  be  deemed  to  be  both  covenants  and  conditions.    All  indemnity,  defense,  and  hold  harmless  obligations  of 
Tenant hereunder shall survive the termination of this Lease.

51.12. Joint and Several Liability.    If  more  than  one  person  is  Tenant,  then  the  obligations  of  Tenant  under  this  Lease 
shall be the joint and several obligations of each of such persons; provided, however, that any act or signature of one or more of any of 
such persons and any notice or refund given to or served on any one of such persons shall be fully binding on each of such persons.

51.13. Counterparts.  This Lease and all documents relating to this Lease, including without limitation, this Lease, any 
addenda, any exhibits, the Work Letter, the Guaranty (if any), and any amendments to any of the foregoing (collectively, together with the 
Lease,  the  “Lease  Documents”)  may  be  executed  in  any  number  of  counterparts,  each  of  which  shall  be  deemed  an  original  for  all 
purposes, and all counterparts shall constitute one and the same instrument.

construed to have been used in the plural (and vice versa), each gender shall be construed to include any other genders, and the word

trust, an estate or any other entity.  

51.15. Severability.  Each provision of this Lease shall be valid and enforceable to the fullest extent permitted by Laws.  
If  any  provision  of  this  Lease  or  the  application  of  such  provision  to  any  person  or  circumstance  shall,  to  any  extent,  be  invalid  or 
unenforceable, the remainder of this Lease, or the application of such provision to persons or circumstances other than those as to which it 
is held invalid or unenforceable, shall not be affected by such invalidity or unenforceability, unless such provision or such application of 
such provision is essential to this Lease.  

51.16. Effective  Upon  Execution.    This  Lease  shall  become  effective  and  binding  upon  the  parties  when  it  has  been 
executed  by  each  of  Landlord  and  Tenant;  notwithstanding  the  fact  that  the  Term  of  this  Lease  (i.e.  Tenant's  rights  of  full  occupancy 
hereunder) will not commence until the Lease Commencement Date.  

51.17. Successors.  Subject to any restriction on transferability contained in this Lease, this Lease shall be binding upon 
and shall inure to the benefit of the successors‑in‑interest and assigns of each party to this Lease.  Nothing in this Paragraph shall create 
any rights enforceable by any person not a party to this Lease, except for the rights of the successors‑in‑interest and permitted assigns of 
each party to this Lease, unless such rights are expressly granted in this Lease to other specifically identified persons.

51.19. Construction.  Each party to this Lease and its legal counsel have had an opportunity to review and revise this 
Lease.    The  rule  of  construction  that  any  ambiguities  are  to  be  resolved  against  the  drafting  party  shall  not  be  employed  in  the 
interpretation of this Lease or any Addendum or Exhibit to this Lease, and such rule of construction is hereby waived by Tenant.

signage criteria, in a written form, for the benefit of the Project and Building, as it deems appropriate. Violations of such Rules, regulations, 
and signage criteria by Tenant or Tenant's Invitees shall constitute a material default of this Lease.

governing  the  Premises,  lease  negotiations,  arrangements,  letters  of  intents,  offers  to  lease,  lease  proposals  or  drafts,  brochures, 
representations,  and  information  conveyed,  whether  oral  or  written,  between  the  parties  hereto  or  their  respective  agents  or

business and an original written record when printed.  Such paper copies or “printouts,” if introduced as evidence in any judicial, arbitral, 
mediation, administrative, or other legal proceeding, will be fully admissible as between the parties to the same extent and under the same 
conditions as other original business records created and maintained in documentary form.  Neither Landlord nor Tenant shall contest the 
admissibility of true and accurate copies of electronically signed documents on the basis of the best evidence rule or as not satisfying the

Civil Code §1938

A commercial property owner or lessor shall state on every lease form or rental agreement executed on or after January 1, 2017, 

(a)
whether or not the subject premises have undergone inspection by a Certified Access Specialist (CASp).

(b)
If  the  subject  premises  have  undergone  inspection  by  a  CASp  and,  to  the  best  of  the  commercial  property  owner’s  or  lessor’s 
knowledge, there have been no modifications or alterations completed or commenced between the date of the inspection and the date of 
the lease or rental agreement that have impacted the subject premises’ compliance with construction-related accessibility standards, the 
commercial property owner or lessor shall provide, prior to execution of the lease or rental agreement, a copy of any report prepared by 
the  CASp  with  an  agreement  from  the  prospective  lessee  or  tenant  that  information  in  the  report  shall  remain  confidential,  except  as 
necessary for the tenant to complete repairs and corrections of violations of construction-related accessibility standards that the lessee or

(c) Making any repairs or modifications necessary to correct violations of construction-related accessibility standards that are noted in a 
CASp report is presumed to be the responsibility of the commercial property owner or lessor, unless otherwise mutually agreed upon by 
the commercial property owner or lessor and the lessee or tenant. The prospective lessee or tenant shall have the opportunity to review 
any CASp report prior to execution of the lease or rental agreement. If the report is not provided to the prospective lessee or tenant at least

(e)
55.53, the commercial property owner or lessor shall state the following on the lease form or rental agreement:

“A Certified Access Specialist (CASp) can inspect the subject premises and determine whether the subject premises comply with all 
of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the 
subject premises, the commercial property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the 
subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall

GUIDELINES FOR AVOIDING MOISTURE AND MOLD PROBLEMS IN THE PREMISES

EXHIBIT "G"

Controlling moisture and proper maintenance are necessary to limit mold growth. Tenant agrees to maintain the Premises in a manner that 
prevents mold growth. Tenant specifically agrees to:

Contact the Management Office IMMEDIATELY to report:

➣ Any  water  leak,  flooding  or  excessive  or  persistent  moisture  in  the  Premises,  storage  room,  garage  or  any  common  area, 

including any surrounding sinks, toilets, washers, dryers, and refrigerators.

➣ Any stains, discoloration, mold growth or musty odor.

➣ Any malfunction of Tenant’s heating or air conditioning system.

➣ Any cracked or broken window.

NOTE: When organic building materials (e.g., wood, drywall) become wet, they can begin to show visible mold growth in as little 
as 24-48 hours. As such, it is imperative that efforts are made to dry materials thoroughly as quickly as possible.

Properly ventilate and de-humidify the Premises:

➣ Ensure the Premises is regularly ventilated by opening doors and windows. Keeping the Premises closed up can result in indoor 

moisture accumulation. Excessive condensation on window interiors can also occur during periods of cold outdoor temperatures.

➣ Use air conditioning, heating, and fans as necessary to keep air circulating throughout the Premises, but avoid running the air 
conditioning  when  doors  and  windows  are  open,  as  this  can  result  in  excessive  condensation  on  air  registers  and  other  cold 
metal surfaces.

➣ To  the  extent  possible,  keep  windows  and  doors  closed  in  damp  or  rainy  weather  conditions  to  avoid  moisture  entering  the 

Premises.

➣ Do not block or cover any heating/ventilation/air-conditioning diffusers, grilles or thermostats with furniture, wall hangings, etc.

➣ Excessive use of a humidifier can contribute to conditions favorable for moisture build-up and mold growth.

➣ Do not maintain a fish tank or other water-filled container without Landlord’s written consent.

Maintain a clean environment in the Premises:

➣ Regularly vacuum and clean the Premises using household cleaners.

➣ Wipe down and dry countertops, windows, windowsills, and air conditioning grilles when moisture condenses on these surfaces.

➣ Do  not  over-water  indoor  plants  and  clean  up  spills  immediately.  All  potted  plants  must  have  a  secondary  container  under  the 

primary container to collect water.

➣ Remove garbage regularly and remove moldy or rotting items (such as food, wet clothing, or other materials) promptly from the

Premises.

➣ Do not bring any personal property into the Premises that is water-damaged or exhibiting mold growth, especially items such as 

clothes, couches, chairs, mattresses, or pillows. 

Prevent moisture buildup in Tenant’s laundry closet if Tenant has a washer/dryer:

➣ Call Landlord to report condensation in the washer and dryer closet. Dry any condensation that does gather.

➣ Use Tenant’s dryer to dry the bulk of Tenant’s laundry. While a small rack may be used for delicate clothing articles, extensive use 

of drying racks can create humidity that may 

 
 
 
lead to moisture problems. Use drying racks in well-ventilated areas and, if possible, use a fan to circulate the air.

➣ Ensure that Tenant’s dryer vent is properly connected and clear of any obstructions.

➣ Clean the lint filter after every use.

Prevent moisture buildup in any closet space:

➣ Do not overfill closets or storage areas with clothes or other soft goods.

➣ Do not allow damp or moist stacks of clothes or other cloth material to lie in piles.

➣ Leave any closet doors ajar to permit ventilation.

➣ Dry wet shoes, coats, clothes and umbrellas before storing. 

Periodically inspect the Premises for moisture and mold:

➣ Inspect  the  inside  of  the  Premises  (both  visually  and  by  smell)  for  the  presence  of  mold  growth  at  least  once  per  month.  The 

inspection will include but is not limited to:

o

o

o

o

o

o

o

window frames, baseboards, walls and carpets;

the ceiling;

any currently or formerly damp material made of cellulose (such as wallpaper, books, papers, and newspapers);

appliances (including washers/dryers/dishwashers and refrigerators);

around all plumbing fixtures (toilets, sinks and below sinks); 

areas with limited air circulation such as closets, shelves and cupboards;

personal property. 

Thank you for your assistance in maintaining a healthful environment.

Tenant  agrees  to  comply  with  all  instructions  and  requirements  necessary  to  prepare  the  Premises  and/or  Project  for  investigation  and 
remediation,  to  control  water  intrusion,  to  control  mold  growth,  or  to  make  repairs.  Storage,  cleaning,  removal,  or  replacement  of 
contaminated or potentially contaminated personal property will be Tenant’s responsibility unless the elevated mold growth was the result 
of Landlord’s negligence, intentional wrongdoing or violation of law. Landlord is not responsible for any condition about which Landlord is 
not aware. Tenant agrees to provide Landlord with copies of all records, documents, sampling data and other material relating to any water 
leak, excessive moisture, or mold conditions in the Premises or Project as soon as Tenant obtains them. Violation of any of the provisions 
of this Exhibit will be a material breach of this Lease.

Due to coastal atmospheric and other conditions, the Premises may develop moisture resulting in mildew and mold. Tenant acknowledges 
that  this  risk  exists  and  assumes  responsibility  for  proper  ventilation  and  housekeeping  of  the  Premises  to  avoid  such  developments. 
Additionally,  to  the  extent  allowed  by  law,  Tenant  assumes  liability  for  any  injuries  or  damages  caused  by  moisture  resulting  in  mildew 
and/or mold to the Premises, and Tenant’s person and/or property as a result of exposure to moisture resulting in mildew and/or mold.

           Exhibit 97

IDEAYA BIOSCIENCES, INC. 
POLICY FOR RECOVERY OF 
ERRONEOUSLY AWARDED COMPENSATION

IDEAYA Biosciences, Inc. (the “Company”) has adopted this Policy for Recovery of Erroneously Awarded Compensation (the 
“Policy”), effective as of November 13, 2023 (the “Effective Date”).  Capitalized terms used in this Policy but not otherwise defined herein 
are defined in Section 11. 

1.

Persons Subject to Policy

This Policy shall apply to current and former Officers of the Company. Each Officer shall be required to sign an acknowledgment 
pursuant to which such Officer will agree to be bound by the terms of, and comply with, this Policy; however, any Officer’s failure to sign 
any such acknowledgment shall not negate the application of this Policy to the Officer.

2.  Compensation Subject to Policy

This Policy shall apply to Incentive-Based Compensation received on or after the Effective Date. For purposes of this Policy, the 
date on which Incentive-Based Compensation is “received” shall be determined under the Applicable Rules, which generally provide that 
Incentive-Based  Compensation  is  “received”  in  the  Company’s  fiscal  period  during  which  the  relevant  Financial  Reporting  Measure  is 
attained or satisfied, without regard to whether the grant, vesting or payment of the Incentive-Based Compensation occurs after the end of 
that period.

3.  Recovery of Compensation

In the event that the Company is required to prepare a Restatement, the Company shall recover, reasonably promptly, the portion 
of  any  Incentive-Based  Compensation  that  is  Erroneously  Awarded  Compensation,  unless  the  Committee  has  determined  that  recovery 
would be Impracticable. Recovery shall be required in accordance with the preceding sentence regardless of whether the applicable Officer 
engaged  in  misconduct  or  otherwise  caused  or  contributed  to  the  requirement  for  the  Restatement  and  regardless  of  whether  or  when 
restated financial statements are filed by the Company.  For clarity, the recovery of Erroneously Awarded Compensation under this Policy 
will not give rise to any person’s right to voluntarily terminate employment for “good reason,” or due to a “constructive termination” (or 
any similar term of like effect) under any plan, program or policy of or agreement with the Company or any of its affiliates.

4.  Manner of Recovery; Limitation on Duplicative Recovery

The Committee shall, in its sole discretion, determine the manner of recovery of any Erroneously Awarded Compensation, which 
may include, without limitation, reduction or cancellation by the Company or an affiliate of the Company of Incentive-Based Compensation 
or  Erroneously  Awarded  Compensation,  reimbursement  or  repayment  by  any  person  subject  to  this  Policy  of  the  Erroneously  Awarded 
Compensation, and, to the extent permitted by law, an offset of the Erroneously Awarded Compensation against other compensation payable 
by the Company or an affiliate of the Company to such person. Notwithstanding the foregoing, unless otherwise 

||

1

 
prohibited  by  the  Applicable  Rules,  to  the  extent  this  Policy  provides  for  recovery  of  Erroneously  Awarded  Compensation  already 
recovered by the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 or Other Recovery Arrangements, the amount of 
Erroneously  Awarded  Compensation  already  recovered  by  the  Company  from  the  recipient  of  such  Erroneously  Awarded  Compensation 
may be credited to the amount of Erroneously Awarded Compensation required to be recovered pursuant to this Policy from such person.

5.  Administration 

This  Policy  shall  be  administered,  interpreted  and  construed  by  the  Committee,  which  is  authorized  to  make  all  determinations 
necessary,  appropriate  or  advisable  for  such  purpose.  The  Board  of  Directors  of  the  Company  (the  “Board”)  may  re-vest  in  itself  the 
authority  to  administer,  interpret  and  construe  this  Policy  in  accordance  with  applicable  law,  and  in  such  event  references  herein  to  the 
“Committee” shall be deemed to be references to the Board.  Subject to any permitted review by the applicable national securities exchange 
or association pursuant to the Applicable Rules, all determinations and decisions made by the Committee pursuant to the provisions of this 
Policy shall be final, conclusive and binding on all persons, including the Company and its affiliates, equityholders and employees. The 
Committee  may  delegate  administrative  duties  with  respect  to  this  Policy  to  one  or  more  directors  or  employees  of  the  Company,  as 
permitted under applicable law, including any Applicable Rules. 

6. 

Interpretation

This Policy will be interpreted and applied in a manner that is consistent with the requirements of the Applicable Rules, and to the 
extent  this  Policy  is  inconsistent  with  such  Applicable  Rules,  it  shall  be  deemed  amended  to  the  minimum  extent  necessary  to  ensure 
compliance therewith. 

7.  No Indemnification; No Liability

The Company shall not indemnify or insure any person against the loss of any Erroneously Awarded Compensation pursuant to 
this Policy, nor shall the Company directly or indirectly pay or reimburse any person for any premiums for third-party insurance policies 
that such person may elect to purchase to fund such person’s potential obligations under this Policy.  None of the Company, an affiliate of 
the Company or any member of the Committee or the Board shall have any liability to any person as a result of actions taken under this 
Policy.

8.  Application; Enforceability

Except as otherwise determined by the Committee or the Board, the adoption of this Policy does not limit, and is intended to apply 
in addition to, any other clawback, recoupment, forfeiture or similar policies or provisions of the Company or its affiliates, including any 
such policies or provisions of such effect contained in any employment agreement, bonus plan, incentive plan, equity-based plan or award 
agreement thereunder or similar plan, program or agreement of the Company or an affiliate or required under applicable law (the “Other 
Recovery Arrangements”). The remedy specified in this Policy shall not be exclusive and shall be in addition to every other 

2

 
 
 
right or remedy at law or in equity that may be available to the Company or an affiliate of the Company.

9.  Severability

The provisions in this Policy are intended to be applied to the fullest extent of the law; provided, however, to the extent that any 
provision of this Policy is found to be unenforceable or invalid under any applicable law, such provision will be applied to the maximum 
extent permitted, and shall automatically be deemed amended in a manner consistent with its objectives to the extent necessary to conform 
to any limitations required under applicable law. 

10.  Amendment and Termination

The Board or the Committee may amend, modify or terminate this Policy in whole or in part at any time and from time to time in 
its  sole  discretion.  This  Policy  will  terminate  automatically  when  the  Company  does  not  have  a  class  of  securities  listed  on  a  national 
securities exchange or association.

11.  Definitions

“Applicable Rules”  means  Section  10D  of  the  Exchange  Act,  Rule  10D-1  promulgated  thereunder,  the  listing  rules  of  the  national

adopted by the Securities and Exchange Commission or any national securities exchange or association on which the Company’s securities 
are listed.

“Committee”  means  the  committee  of  the  Board  responsible  for  executive  compensation  decisions  comprised  solely  of

directors serving on the Board.

“Erroneously  Awarded  Compensation”  means  the  amount  of  Incentive-Based  Compensation  received  by  a  current  or  former

“Exchange Act” means the Securities Exchange Act of 1934, as amended.

3

 
 
 
 
 
 
 
 
 
 
 
“Impracticable”  means  (a)  the  direct  costs  paid  to  third  parties  to  assist  in  enforcing  recovery  would  exceed  the  Erroneously 
Awarded Compensation; provided that the Company (i) has made reasonable attempts to recover the Erroneously Awarded Compensation, 
(ii)  documented  such  attempt(s),  and  (iii)  provided  such  documentation  to  the  relevant  listing  exchange  or  association,  (b)  to  the  extent 
permitted by the Applicable Rules, the recovery would violate the Company’s home country laws pursuant to an opinion of home country 
counsel; provided that  the  Company  has  (i)  obtained  an  opinion  of  home  country counsel, acceptable to the relevant listing exchange or 
association, that recovery would result in such violation, and (ii) provided such opinion to the relevant listing exchange or association, or (c) 
recovery  would  likely  cause  an  otherwise  tax-qualified  retirement  plan,  under  which  benefits  are  broadly  available  to  employees  of  the 
Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and the regulations thereunder.

“Incentive-Based Compensation” means, with respect to a Restatement, any compensation that is granted, earned, or vested based

requirement under securities laws, including restatements that correct an error in previously issued financial statements (a) that is material 
to the previously issued financial statements or (b) that would result in a material misstatement if the error were corrected in the current 
period or left uncorrected in the current period.

“Three-Year Period” means, with respect to a Restatement, the three completed fiscal years immediately preceding the date that 
the Board, a committee of the Board, or the officer or officers of the Company authorized to take such action if Board action is not required, 
concludes, or reasonably should have concluded, that the Company is required to prepare such Restatement, or, if earlier, the date on which 
a court, regulator or other legally authorized body directs the Company to prepare such Restatement. The “Three-Year Period” also includes 
any transition period (that results from a change in the Company’s fiscal year) within or immediately following the three completed fiscal 
years identified in the preceding sentence. However, a transition period between the last day of the Company’s previous fiscal year end and 
the first day of its new fiscal year that comprises a period of nine to 12 months shall be deemed a completed fiscal year.
