Item 1.     Business

Company Overview

BUSINESS

Mirati  Therapeutics,  Inc.  is  a  clinical-stage  oncology  company  developing  novel  therapeutics  to  address  the  genetic 

and immunological promoters of cancer. 

We have two KRAS inhibitor programs. Adagrasib is an investigational, selective, specific, potent and orally available 
KRAS  G12C  inhibitor  in  clinical  development  as  a  monotherapy  and  in  combination  with  other  agents.  Adagrasib  is  the 
provisionally filed nonproprietary name for MRTX849. MRTX1133 is an investigational, selective, specific and potent KRAS 
G12D inhibitor in preclinical development. 

Sitravatinib  is  an  investigational  spectrum-selective  kinase  inhibitor  designed  to  potently  inhibit  receptor  tyrosine 

kinases (“RTK”s) and enhance immune responses through the inhibition of immunosuppressive signaling. 

MRTX1719 is an internally discovered investigational synthetic lethal PRMT5 inhibitor designed to specifically target 

the PRMT5/methylthioadensoine (MTA) complex in preclinical development.

The Company also has additional preclinical programs of potentially first-in-class and best-in-class product candidates 
specifically designed to address mutations and tumors where few treatment options exist. We approach all of our programs with 
a singular focus: to translate our deep understanding of the molecular drivers of cancer into better therapies and better outcomes 
for patients.

KRAS Inhibitor Programs 

The RAS family of genes is the most commonly mutated oncogene and mutations in this gene family occur in up to 
approximately  25%  of  all  human  cancers.  Among  the  RAS  family  members,  mutations  most  frequently  occur  in  KRAS 
(approximately 85% of all RAS family mutations). Tumors characterized by KRAS mutations are commonly associated with 
poor prognosis and resistance to therapy. Nonclinical studies have demonstrated that cancer cells exhibiting KRAS mutations 
are  highly  dependent  on  KRAS  function  for  cell  growth  and  survival.  Our  KRAS  inhibitor  programs  are  focused  on  the 
discovery and development of small molecule compounds that target KRAS G12C and G12D. We are pursuing development of 
our KRAS G12C and KRAS G12D inhibitor programs in both single agent and rational combination approaches.

Adagrasib, a selective KRAS G12C inhibitor

Adagrasib,  our  lead  KRAS  G12C  compound,  is  an  investigational,  selective,  specific,  potent  and  orally  available 
KRAS G12C inhibitor and is in clinical development varying from Phase 1 through Phase 3. Adagrasib is designed to directly 
inhibit  KRAS  G12C  mutations.  KRAS  G12C  mutations  are  present  in  approximately  14%  of  non-small  cell  lung  cancer 
(“NSCLC”) adenocarcinoma patients, 3-4% of colorectal cancer (“CRC”) patients, 2% of pancreatic cancer patients, as well as 
smaller percentages of several other difficult-to-treat cancers. 

We received U.S. Food and Drug Administration (“FDA”) authorization of our investigational new drug application 
(“IND”) for adagrasib in November 2018, and in January 2019, we initiated the dose escalation phase of KRYSTAL-1, a Phase 
1/2  multiple  expansion  cohort  clinical  trial  evaluating  adagrasib  in  patients  with  advanced  solid  tumors  that  harbor  KRAS 
G12C  mutations  both  in  monotherapy  and  in  combination  with  other  anticancer  therapies.  Following  single  agent  dose 
escalation,  the  KRYSTAL-1  trial  was  expanded  into  multiple  cohorts  in  which  adagrasib  is  being  evaluated  both  in 
monotherapy and in combination with other compounds in patients with NSCLC, CRC and those with other tumors that carry 
the KRAS G12C mutation.

In December 2021, we completed our New Drug Application (“NDA“) submission to the FDA for adagrasib for the 
treatment  of  patients  with  previously  treated  KRAS  G12C-mutated  NSCLC  who  have  received  prior  systemic  therapy.  In 
February 2022, the FDA accepted the NDA and assigned a Prescription Drug User Fee Action (“PDUFA”) date of December 
14,  2022.  The  NDA  is  being  reviewed  by  the  FDA  for  Accelerated  Approval  (Subpart  H),  which  allows  for  the  approval  of 
drugs  that  treat  serious  conditions,  and  that  fill  an  unmet  medical  need  based  on  a  surrogate  endpoint.  In  addition,  this 
application  is  being  reviewed  under  the  FDA  Real-Time  Oncology  Review  pilot  program,  which  aims  to  explore  a  more 
efficient review process that ensures safe and effective treatments are made available to patients as early as possible. Adagrasib 
has also achieved Breakthrough Therapy Designation as a potential treatment for patients with NSCLC who harbor the KRAS 
G12C mutation following prior systemic therapy. The Company also has an Expanded Access Program for adagrasib for the 
treatment of eligible patients with KRAS G12C-mutated cancers regardless of tumor type in the United States.

The KRYSTAL-1 trial is evaluating the combination of adagrasib and a PD-1 inhibitor (pembrolizumab) in patients 
with  NSCLC,  the  combination  of  adagrasib  and  a  pan-EGFR  inhibitor  (afatinib)  in  patients  with  advanced  NSCLC,  and  the 
combination of adagrasib and an anti-EGFR antibody (cetuximab) in patients with CRC. In 2020, we initiated KRYSTAL-2, a 
Phase  1/2  clinical  trial  evaluating  the  combination  of  adagrasib  and  a  SHP-2  inhibitor  (TNO-155)  in  patients  with  advanced 
NSCLC  and  advanced  CRC.  In  2021,  we  initiated  KRYSTAL-14,  a  Phase  1/2  clinical  trial  evaluating  the  combination  of 
adagrasib and a SOS1 inhibitor (BI 1701963) in patients with advanced NSCLC, and we initiated KRYSTAL-16, a Phase 1/1b 
clinical  trial  evaluating  the  combination  of  adagrasib  and  a  CDK4/6  inhibitor  (palbociclib)  in  patients  with  advanced  solid 
tumors with KRAS G12C mutation.

In  the  fourth  quarter  of  2021,  we  announced  preliminary  results  from  the  Phase  1b  cohort  of  the  KRYSTAL-1  trial 
evaluating  the  combination  of  adagrasib  and  a  PD-1  inhibitor  (pembrolizumab)  in  eight  patients  with  KRAS  G12C-mutated 
first-line NSCLC. The preliminary results support moving forward with a 400mg twice daily dose (“BID”) of adagrasib with 
full  dose  pembrolizumab,  which  will  be  evaluated  in  an  ongoing  Phase  2  clinical  trial.  The  Phase  1b  data  showed  adagrasib 
400mg BID plus pembrolizumab had a manageable tolerability profile, with no observed Grade 4 or Grade 5 adverse events. Of 
the seven patients evaluable for a response as of October 21, 2021, four had a confirmed RECIST-defined partial response and 
one  additional  patient,  who  is  still  on  study,  experienced  49%  tumor  regression  in  the  first  scan,  which  allowed  for  tumor 
resection prior to achieving a RECIST-defined confirmed response. The disease control rate (“DCR”) was 100%, with all seven 
patients  exhibiting  tumor  regression  ranging  from  37%  to  92%.  With  a  median  follow  up  of  9.9  months,  five  of  the  seven 
patients remained on treatment, as of the data cutoff date, and had been on treatment for 8 to 11 months.

On  September  20,  2021,  we  announced  that  we  completed  an  analysis  in  the  intent-to-treat  population  of  the 
registration enabling cohort of KRYSTAL-1, the Phase 1/2 clinical trial evaluating adagrasib at 600mg BID as a monotherapy 
treatment for patients in at least 2nd line NSCLC. The analysis showed an objective response rate (“ORR”) of 43% and a DCR 
of 80%, based on central independent review, as of June 15, 2021.

In  the  third  quarter  of  2021,  we  amended  KRYSTAL-7,  the  Phase  2  clinical  trial  evaluating  the  combination  of 
adagrasib at 400mg BID and a PD-1 inhibitor (pembrolizumab) in patients with NSCLC stratified by <1% Tumor Proportion 
Score (“TPS”) score and ≥1% TPS score.

In  the  first  quarter  of  2021,  we  initiated  two  registration-enabling  Phase  3  clinical  trials.  The  first  clinical  trial, 
KRYSTAL-12, is evaluating adagrasib as a monotherapy randomized against docetaxel in patients with 2nd line NSCLC. The 
second  clinical  trial,  KRYSTAL-10,  is  evaluating  the  combination  of  adagrasib  and  an  anti-EGFR  antibody  (cetuximab) 
randomized against chemotherapy in patients with 2nd line CRC.

On  September  19,  2021,  at  the  European  Society  for  Medical  Oncology  Congress  2021,  we  presented  preliminary 
results from the cohort of the KRYSTAL-1 Phase 1/2 clinical trial evaluating adagrasib at 600mg BID as both a monotherapy 
treatment and in combination with cetuximab for patients with heavily pretreated colorectal cancer harboring a KRAS G12C 
mutation.

As of May 25, 2021, the adagrasib monotherapy arm (n=46) had a median follow up of 8.9 months. Of the evaluable 
patients  (n=45),  preliminary  results  showed  an  investigator  assessed  response  rate  (“RR”)  of  22%,  including  one 
unconfirmed partial response (“PR”), and a DCR of 87%; the median duration of response (“DOR”) was 4.2 months. 
In all enrolled patients, the median progression free survival (“PFS”) was 5.6 months (95% confidence interval (“CI”): 
4.1,8.3).

As of July 9, 2021, the adagrasib plus cetuximab arm (n=32) had a median follow up of 7 months. Of the evaluable 
patients (n=28), preliminary results showed an investigator assessed RR of 43%, including two unconfirmed PRs and a 
DCR  of  100%.  After  the  data  cutoff  date,  of  the  two  unconfirmed  PRs,  follow  up  scans  showed  one  patient  had  a 
confirmed PR, and the second patient progressed.

Adagrasib monotherapy and in combination with cetuximab was well-tolerated in this study, with a manageable safety 
profile. Grade 3/4 treatment related adverse events (“TRAEs”) were observed in 30% of patients treated with adagrasib 
alone,  and  in  16%  of  patients  treated  with  the  combination.  Treatment  related  adverse  events  led  to  treatment 
discontinuation in 6% of patients who received combination therapy and in none (0%) of those who received adagrasib 
monotherapy. No Grade 5 TRAEs were observed in either treatment arm.

On  October  9,  2021,  at  the  33rd  EORTC-NCI-AACR  Symposium  on  Molecular  Targets  and  Therapeutics,  we 
presented  preliminary  results  from  a  cohort  of  the  KRYSTAL-1  clinical  trial  evaluating  adagrasib  at  600mg  BID  as 

3

monotherapy  for  patients  with  pancreatic  ductal  adenocarcinoma  harboring  a  KRAS  G12C  mutation.  arm  (n=12).  Of  the 
evaluable patients (n=10), preliminary results showed an investigator assessed RR of 50%, including an unconfirmed PR, and a 
DCR of 100%.

Preliminary efficacy data was assessed as of August 30, 2020 in six patients with advanced solid tumors, other than 
NSCLC and CRC, treated with adagrasib as a monotherapy at 600mg BID dose from a Phase 1/1b cohort. One patient each 
with  pancreatic,  ovarian,  endometrial  and  cholangiocarcinoma  tumors  were  treated  and  had  a  confirmed  PR  to  therapy.  Two 
appendiceal cancer patients had stable disease and all six eligible patients remained on treatment.

Adagrasib Development in Collaboration with Zai Lab Ltd. (“Zai”)

In May 2021, we entered into a Collaboration and License Agreement with Zai (the “Zai Agreement”). Under the Zai 
Agreement,  we  granted  Zai  the  right  to  research,  develop,  manufacture  and  exclusively  commercialize  adagrasib  in  all 
indications  in  China,  Macau,  Hong  Kong  and  Taiwan  (collectively,  the  “Zai  Licensed  Territory”),  with  Mirati  retaining 
exclusive rights for the development, manufacture and commercialization of adagrasib outside the Zai Territory and certain co-
commercialization, manufacture, and development rights in the Zai Licensed Territory.

MRTX1133, a selective KRAS G12D inhibitor

MRTX1133,  our  lead  KRAS  G12D  compound,  has  been  identified  as  a  clinical  development  candidate  and  is  an 
investigational,  selective,  specific  and  potent  inhibitor  of  KRAS  G12D  and  is  currently  in  preclinical  development.  KRAS 
G12D  mutations  have  been  detected  in  over  25  different  types  of  cancer,  including  pancreatic,  colon,  lung  and  endometrial 
adenocarcinoma. The prevalence of cancers harboring KRAS G12D mutations exceeds the prevalence of KRAS G12C positive 
cancers by greater than two-fold and is an area of significant unmet medical need.

On October 25, 2020 we announced initial preclinical in vivo data from MRTX1133. Based on preclinical analyses, 
MRTX1133 has a projected human half-life of approximately 50 hours and exhibits a low propensity for drug interactions or 
off-target  pharmacology.  MRTX1133  demonstrated  tumor  regression  in  multiple  in  vivo  tumor  models,  including  pancreatic 
and colorectal cancers. MRTX1133 has a low predicted target plasma concentration, based on its potency and high unbound 
fraction,  and  our  goal  is  to  achieve  near  complete  and  sustained  target  inhibition  and  maximal  anti-tumor  activity.  We  have 
prioritized  a  long-acting  IV  injectable  drug  product  strategy,  including  liposome-based  formulations,  that  are  designed  to 
optimize and extend the duration of KRAS G12D target inhibition as we progress towards IND-enabling studies. We are also 
continuing to evaluate strategies to enhance oral absorption to potentially enable development of a solid oral dose form.

Sitravatinib

Sitravatinib is a spectrum-selective kinase inhibitor in Phase 3 clinical development and is designed to potently inhibit 
receptor  tyrosine  kinases  (“RTK”s),  including  TAM  family  receptors  (TYRO3,  Axl,  Mer),  split  family  receptors  (VEGFR2, 
KIT) and RET. Sitravatinib’s potent inhibition of TAM and split family RTKs may overcome resistance to checkpoint inhibitor 
therapy  through  targeted  reversal  of  an  immunosuppressive  tumor  microenvironment,  enhancing  antigen-specific  T  cell 
response and expanding dendritic cell-dependent antigen presentation. There are over 100,000 2nd or 3rd line NSCLC patients in 
the  United  States  and  Europe,  who  have  derived  prior  clinical  benefit  following  treatment  with  a  PD-(L)1  inhibitor,  with 
approximately 70,000 of these patients being of the non-squamous histology.

Sitravatinib in Combination with Nivolumab

As an immuno-oncology agent, sitravatinib is being evaluated in combination with nivolumab (OPDIVO®), Bristol-
Myers  Squibb  Company’s  (“BMS”)  anti-PD-1  checkpoint  inhibitor,  in  patients  with  NSCLC  who  have  experienced 
documented disease progression following treatment with a checkpoint inhibitor. Sitravatinib is also being developed in certain 
Asian  territories  in  collaboration  with  BeiGene,  Ltd.  (“BeiGene”)  which  is  evaluating  sitravatinib  in  combination  with 
tislelizumab, BeiGene’s anti-PD-1 checkpoint inhibitor, in a number of advanced solid tumors.

We  are  enrolling  an  ongoing  Phase  3  clinical  trial  in  2nd  line  non-squamous  NSCLC  patients  whose  tumors  have 
progressed on prior therapy with platinum-chemotherapy in combination with a checkpoint inhibitor or 3rd line non-squamous 
NSCLC patients who have received chemotherapy followed by a checkpoint inhibitor. The Phase 3 clinical trial is comparing 
the  combination  of  sitravatinib  plus  nivolumab  randomized  to  docetaxel.  The  statistical  design  of  the  Phase  3  clinical  trial 
includes  an  interim  analysis  of  overall  survival  that  we  believe,  if  positive,  could  support  an  NDA  submission  seeking  full 
approval.

In January 2019, we announced a clinical trial collaboration with BMS in connection with the aforementioned Phase 3 
clinical  trial.  Under  the  terms  of  the  collaboration,  we  are  sponsoring  and  funding  the  clinical  trial  and  BMS  is  providing 
nivolumab at no cost. We maintain global development and commercial rights to sitravatinib outside of certain Asian territories 
and  Australia  and  New  Zealand,  where  we  have  partnered  with  BeiGene,  and  we  are  free  to  develop  the  program  in 
combination with other agents.

We also have several Phase 2 clinical trials in which we are evaluating sitravatinib in combination with nivolumab in 
patients with NSCLC, urothelial carcinoma or other cancers who have experienced documented disease progression following 
prior treatment with chemotherapy and/or a checkpoint inhibitor. On September 20, 2021, we announced results from a post 
hoc exploratory  analysis of the Phase 2 study, MRTX-500, in patients with nonsquamous NSCLC with prior clinical benefit 
from checkpoint inhibitor therapy and where anti-PD-(L)1 was the most recent line of therapy (n=68) and a median follow-up 
of 33.6 months. The median overall survival was 14.9 months (95% CI: 9.3, 21.1), with 56% and 32% of these patients alive at 
one  year  and  two  years,  respectively.  The  ORR  was  18%,  with  3%  of  patients  achieving  a  complete  response  and  15%  of 
patients achieving a PR. The median DOR was 12.8 months.

Sitravatinib Development in Collaboration with BeiGene

In January 2018, we entered into a Collaboration and License Agreement with BeiGene (the “BeiGene Agreement”). 
Under  the  BeiGene  Agreement,  we  granted  BeiGene  an  exclusive  license  to  develop,  manufacture  and  commercialize 
sitravatinib  in  Asia  (excluding  Japan  and  certain  other  countries),  Australia  and  New  Zealand  (the  “BeiGene  Licensed 
Territory”), and we retained exclusive rights for the development, manufacturing and commercialization of sitravatinib outside 
the BeiGene Licensed Territory.

In  November  2018,  we  dosed  the  first  patient  under  the  BeiGene  Agreement  to  assess  the  safety  and  tolerability, 
pharmacokinetics and preliminary anti-tumor activity of sitravatinib in combination with BeiGene’s investigational anti-PD-1 
antibody,  tislelizumab,  in  patients  with  advanced  solid  tumors.  BeiGene’s  clinical  trials  will  evaluate  the  combination  of 
sitravatinib and tislelizumab in patients with solid tumors including NSCLC, renal cell carcinoma, hepatocellular cancer, gastric 
cancer and ovarian cancer.

MRTX1719, a synthetic lethal MTA cooperative PRMT5 inhibitor

MRTX1719, our lead synthetic MTA cooperative lethal PRMT5 inhibitor is an investigational, selective, potent and 
orally available inhibitor targeting the PRMT5/MTA complex in methylthioadenosine phosphorylase (MTAP)-deleted cancers 
and is in Phase 1/2 clinical development. The MTAP deletion is present in approximately 10 percent of all cancers and is the 
most frequently observed gene deletion event (MTAP/CDKN2A) across several cancer types. Cancers with an MTAP deletion, 
such as pancreatic, lung, and bladder cancers, are associated with a poor prognosis, representing a significant unmet medical 
need.

In preclinical studies, MRTX1719 has demonstrated a greater than 70-fold selectivity for MTAP-deleted cells relative 
to normal cells and demonstrated near complete and sustained inhibition of PRMT5 in tumor xenografts resulting in significant 
tumor growth inhibition or tumor regression in MTAP-deleted tumor models. The ability to target the PRMT5/MTA complex 
provides an opportunity to selectively target tumor cells harboring the MTAP gene deletion which exhibit an abnormally high 
level of MTA (methylthioadenosine) compared with normal cells.  This is anticipated to provide an increased therapeutic index 
relative to first generation PRMT5 inhibitors that do not specifically target the PRMT5/MTA complex. In the first quarter of 
2022, we initiated a Phase 1/2 multiple expansion cohort trial to evaluate MRTX1719 in patients with advanced, unresectable or 
metastatic solid tumor malignancy with homozygous deletion of the MTAP gene.

Market and Competition

NSCLC Market

The  National  Cancer  Institute  estimates  that  in  2021,  approximately  236,000  patients  in  the  United  States  (“U.S.”) 
were diagnosed with lung cancer and 132,000 died due to the disease.  Lung cancer represents almost 12% of all new cancer 
cases in the U.S., and 22% of all cancer deaths. According to the American Cancer Society, approximately 84% of lung cancers 
are  NSCLC.  The  five-year  survival  rate  for  lung  cancer  patients  is  25%,  indicating  a  significant  need  for  novel  therapies  to 
extend overall survival in this patient population.

The  prognosis  for  advanced  NSCLC  is  poor,  and  the  primary  objective  of  treating  late-stage  disease  is  to  prolong 
overall survival, delay disease progression and control symptoms. The treatment algorithm for advanced NSCLC has changed 

5

significantly  following  recent  approvals  and  label  expansions  of  immuno-oncology  agents,  specifically  immune  checkpoint 
inhibitors.  In 2015, the FDA approved OPDIVO®, an anti-PD-1 monoclonal antibody, and the first immuno-oncology agent 
approved for the treatment of squamous NSCLC. The approval of OPDIVO® in NSCLC was subsequently followed by FDA 
approval of three additional immuno-oncology agents in NSCLC, KEYTRUDA®, TECENTRIQ®, and IMFINZI®.  These four 
agents, approved for multiple indications including NSCLC, accounted for over $27 billion in global sales in 2020.

Despite  the  advances  in  patient  outcomes  demonstrated  by  approved  immuno-oncology  therapies  in  NSCLC,  a 
significant  patient  need  remains.    The  percentage  of  patients  who  respond  to  approved  immuno-oncology  treatments  is  quite 
low, and of the patients that respond, the majority will still experience disease progression.

NSCLC  represents  a  heterogeneous  patient  population  with  diverse  tumor  histology  and  underlying  genomic 
aberrations.  The  clinical  and  commercial  success  of  leading  targeted  agents  across  multiple  indications,  including  NSCLC, 
demonstrates the potential of new targeted treatments for cancer. 

Competition

KRAS G12C

We are aware of at least six companies who currently have competing commercial or clinical-stage direct KRAS G12C 
inhibitor  programs:  Amgen,  Inc.,  F.  Hoffman-LaRoche  Ltd.,  Eli  Lilly  and  Company,  Merck  &  Co.,  Inc.,  Novartis  AG  and 
Boehringer Ingelheim International GmbH.

Sitravatinib in Combination with Immune Checkpoint Inhibitors

There  are  several  immune  checkpoint  inhibitors  currently  approved  for  use  as  single  agents  to  treat  multiple  tumor 
types, including NSCLC. To augment the efficacy of these agents, combination studies are being conducted with a variety of 
potentially synergistic mechanisms, including inhibitors of CTLA-4, LAG3, TIM-3, TIGIT and CSF-1R, among others. Most of 
these  combination  studies  are  being  conducted  in  patients  who  are  naïve  to  immune  checkpoint  inhibitor  therapy.  Direct 
mechanistic competitors to sitravatinib in combination with checkpoint inhibitors in NSCLC patients who had previously failed 
checkpoint inhibitor therapy include CABOMETYX® (Exelixis, Inc.) and LENVIMA® (Eisai Co., Ltd.), both anti-VEGF agents 
that  also  inhibit  other  receptor  tyrosine  kinases.  Additionally,  there  are  numerous  other  potential  competitors  with  kinase 
inhibitors  that  are  being  evaluated  in  combination  with  checkpoint  inhibitors  in  NSCLC  patients  who  had  previously  failed 
checkpoint inhibitor therapy in earlier lines of treatment.

Oncology

In addition to companies that have kinase inhibitors addressing our targets of interest, our competition also includes 
hundreds  of  private  and  publicly  traded  companies  that  operate  in  the  area  of  oncology  but  have  therapeutics  with  different 
mechanisms of action.  The oncology market in general is highly competitive with over 1,000 molecules currently in clinical 
development. Other important competitors, in addition to those mentioned above, are small and large biotechnology companies, 
specialty  and  regional  pharmaceutical  companies  and  multinational  pharmaceutical  companies,  including  but  not  limited  to 
AbbVie  Inc.,  AstraZeneca  plc,  Bristol-Myers  Squibb  Company,  Gilead  Sciences,  Inc.,  GlaxoSmithKline  plc,  Johnson  & 
Johnson, Pfizer Inc., Sanofi S.A., and Takeda Pharmaceutical Co.

Intellectual Property

Our  goal  is  to  obtain,  maintain  and  enforce  patent  protection  wherever  appropriate  for  our  product  candidates, 
formulations, processes, methods and any other proprietary technologies both in the United States and in other countries. We 
typically file for patents in the United States with counterparts in certain countries in Europe and certain key market countries in 
the rest of the world, thereby covering the major pharmaceutical markets. As of December 31, 2021, we own or co-own U.S. 
patents  and  patent  applications  and  their  foreign  counterparts,  including  34  issued  U.S.  patents,  including  one  for  KRAS 
inhibitors  and  15  for  sitravatinib  and  other  kinase  inhibitors.  Mirati’s  patents  and  patent  applications  have  expiration  dates 
ranging from 2023-2041. In some instances, patent terms can be increased or decreased, depending on the laws and regulations 
of the country or jurisdiction that issued the patent. 

6

Manufacturing

We do not own or operate manufacturing facilities for the production of any of our product candidates, nor do we plan 
to  develop  our  own  manufacturing  operations  in  the  foreseeable  future.  We  currently  depend  on  third-party  contract 
manufacturers for all of our required raw materials and finished products for our preclinical and clinical trials.

Manufacturers of our products are required to comply with applicable FDA manufacturing requirements contained in 
the  FDA’s  Current  Good  Manufacturing  Practices  (“cGMP”)  regulations.  cGMP  regulations  require,  among  other  things, 
quality  control  and  quality  assurance,  as  well  as  corresponding  maintenance  of  records  and  documentation.  Pharmaceutical 
product manufacturers and other entities involved in the manufacture and distribution of approved pharmaceutical products 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 and other laws. Accordingly, manufacturers must 
continue  to  expend  time,  money,  and  effort  in  the  area  of  production  and  quality  control  to  maintain  cGMP  compliance. 
Discovery of problems with a product after approval may result in restrictions on a product, manufacturer or holder of an NDA, 
including withdrawal of the product from the market. In addition, changes to the manufacturing process generally require prior 
FDA approval before being implemented.

Government Regulation

The Regulatory Process for Drug Development

Our  business  activities,  including  the  manufacturing  of  our  product  candidates  and  our  ongoing  research  and 
development activities are subject to extensive regulation by numerous governmental authorities in the United States and other 
countries.  Regulation  by  these  government  authorities  is  a  significant  component  in  the  development,  manufacture  and 
commercialization  of  pharmaceutical  products  and  services.  Before  marketing  in  the  United  States,  any  new  drug  developed 
must undergo rigorous preclinical testing, clinical trials and an extensive regulatory clearance process implemented by the FDA 
under the Federal Food, Drug, and Cosmetic Act, as amended (the “FDCA”). The FDCA and other various federal, state and 
foreign  statutes  govern  or  influence  the  research,  testing,  manufacture,  safety,  labeling,  storage,  recordkeeping,  approval, 
promotion,  marketing,  distribution,  post-approval  monitoring  and  reporting,  sampling,  quality,  and  import  and  export  of  our 
medicines. State, local, and other authorities also regulate pharmaceutical manufacturing. 

Applicable legislation requires licensing of manufacturing and contract research facilities, carefully controlled research 
and  testing  of  products,  and  governmental  review  and/or  approval  of  results  prior  to  marketing  therapeutic  products. 
Additionally,  adherence  to  good  laboratory  practices  (“GLP”)  and  good  clinical  practices  (“GCP”)  during  nonclinical  and 
clinical  testing  and  cGMP  during  production  is  required.  Our  manufacturing  CMOs  are  subject  to  periodic  inspection  by  the 
FDA  and  other  foreign  equivalents  to  ensure  that  they  are  operating  in  compliance  with  cGMP  requirements.  In  addition, 
marketing  authorization  for  each  new  medicine  may  require  a  rigorous  manufacturing  pre-approval  inspection  by  regulatory 
authorities. Post approval, there are strict regulations regarding changes to the manufacturing process, and, depending on the 
significance of the change, changes may require prior FDA approval. FDA regulations also require investigation and correction 
of any deviations from cGMP and impose reporting and documentation requirements upon us and any third-party manufacturers 
that we may decide to use. 

In  addition,  we  are  subject  to  other  state  and  federal  laws,  including,  among  others,  anti-kickback  laws,  fraud  and 
abuse, false claims laws, Sunshine Act, patient protection and affordable care, data privacy and security laws and regulations, 
and transparency laws that restrict certain business practices in the pharmaceutical industry. Violations of these healthcare laws 
can result in significant penalties, including civil, criminal and administrative penalties. Moreover, government coverage and 
reimbursement policies will both directly and indirectly impact our ability to successfully commercialize any future approved 
products,  and  such  coverage  and  reimbursement  policies  will  be  impacted  by  enacted  and  any  applicable  future  healthcare 
reform and drug pricing measures.

U.S. Pharmaceutical Product Development Process

To establish a new product candidate’s safety and efficacy, the FDA requires companies seeking approval to market a 
pharmaceutical drug product to submit extensive preclinical and clinical data, along with other information, for each indication 
for  which  the  product  will  be  labeled.  The  data  and  information  are  submitted  to  the  FDA  in  the  form  of  a  New  Drug 
Application (NDA), which must be accompanied by payment  of a significant user fee unless a waiver or exemption applies. 
Generating  the  required  data  and  information  for  an  NDA  takes  many  years  and  requires  the  expenditure  of  substantial 
resources.  Information  generated  in  this  process  is  susceptible  to  varying  interpretations  that  could  delay,  limit  or  prevent 
regulatory  approval  at  any  stage  of  the  process.  The  failure  to  demonstrate  adequately  the  quality,  safety  and  efficacy  of  a 

7

product candidate under development would delay or prevent regulatory approval of the product candidate. Under applicable 
laws and FDA regulations, each NDA submitted for FDA approval is given an internal administrative review within 60 days 
following  submission  of  the  NDA.  If  deemed  sufficiently  complete  to  permit  a  substantive  review,  the  FDA  will  “file”  the 
NDA.  The  FDA  can  refuse  to  file  any  NDA  that  it  deems  incomplete  or  not  properly  reviewable.  The  FDA  has  established 
internal goals of eight months from submission for priority review of NDAs that cover new product candidates that offer major 
advances in treatment or provide a treatment where no adequate therapy exists, and 12 months from submission for the standard 
review  of  NDAs.  However,  the  FDA  is  not  legally  required  to  complete  its  review  within  these  periods,  these  performance 
goals  may  change  over  time  and  the  review  is  often  extended  by  FDA  requests  for  additional  information  or  clarification. 
Moreover,  the  outcome  of  the  review,  even  if  generally  favorable,  may  not  be  an  actual  approval  but  a  “complete  response 
letter” that describes additional work that must be done before the NDA can be approved. Before approving an NDA, the FDA 
can  choose  to  inspect  the  facilities  at  which  the  product  is  manufactured  and  will  not  approve  the  product  unless  the 
manufacturing  facility  complies  with  GMPs.  The  FDA  may  also  audit  sites  at  which  clinical  trials  have  been  conducted  to 
determine  compliance  with  GCPs  and  data  integrity.  The  FDA’s  review  of  an  NDA  may  also  involve  review  and 
recommendations by an independent FDA advisory committee, particularly for novel indications. The FDA is not bound by the 
recommendation  of  an  advisory  committee.  Further,  the  FDA  may  require  that  certain  contraindications,  warnings  or 
precautions be included in the product labeling.

FDA Regulation of Companion Diagnostics

As part of our clinical development plans, we are exploring the use of companion diagnostics to identify patients most 
likely to respond to our product candidates. Companion diagnostics are classified as medical devices under the FDCA in the 
United States and similarly in other foreign regulations. In the United States, the FDA regulates the medical device design and 
development, preclinical and clinical testing, premarket clearance or approval, registration and listing, manufacturing, labeling, 
storage,  reporting,  recordkeeping,  advertising  and  promotion,  export  and  import,  sales  and  distribution,  and  post-market 
surveillance of medical devices. Unless an exemption applies, companion diagnostics require marketing clearance or approval 
from the FDA prior to commercial distribution. The two primary types of FDA marketing authorization applicable to a medical 
device are premarket notification, also called 510(k) clearance, and premarket approval (“PMA”).

The FDA previously has required in vitro companion diagnostics intended to select the patients who will respond to 
the  cancer  treatment  to  obtain  a  510(k)  clearance  or  PMA  simultaneously  with  approval  of  the  drug.  Based  on  the  draft 
guidance, and the FDA’s past treatment of companion diagnostics, we believe that the FDA will require a PMA for one or more 
companion  diagnostics  to  identify  patient  populations  suitable  for  our  product  candidates.  The  review  of  these  companion 
diagnostics in conjunction with the review of our product candidates involves coordination of review by the FDA’s Center for 
Drug Evaluation and Research and by the FDA’s Center for Devices and Radiological Health.

Pharmaceutical Coverage, Pricing and Reimbursement

In the United States and markets in other countries, sales of any products for which we receive regulatory approval for 
commercial  sale  will  depend  in  part  on  the  availability  of  coverage  and  adequate  reimbursement  from  third-party  payors, 
including government authorities, managed care providers, private health insurers and other organizations. In the United States, 
private health insurers and other third-party payors often provide reimbursement for products and services based on the level at 
which the government (through the Medicare or Medicaid programs) provides reimbursement for such products and services. 
There is no uniform coverage and reimbursement policy among third-party payors in the United States; however, private third-
party payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Third-
party  payors  are  increasingly  examining  the  medical  necessity  and  cost-effectiveness  of  medical  products  and  services  in 
addition to their safety and efficacy and, accordingly, significant uncertainty exists as to the coverage and reimbursement status 
of newly approved therapeutics. In particular, in the United States, the European Union and other potentially significant markets 
for our product  candidates, government authorities and third-party payors are increasingly attempting to limit or regulate the 
price of medical products and services, particularly for new and innovative products and therapies, which often has resulted in 
average  selling  prices  that  are  lower  than  they  would  otherwise  be.  The  increased  emphasis  on  managed  healthcare  in  the 
United  States  and  on  country  and  regional  pricing  and  reimbursement  controls  in  the  European  Union  will  put  additional 
pressure on product pricing, reimbursement and utilization, which may adversely affect our future product sales and results of 
operations.  These  pressures  can  arise  from  rules  and  practices  of  managed  care  groups,  judicial  decisions  and  governmental 
laws and regulations related to Medicare, Medicaid and healthcare reform, pharmaceutical reimbursement policies and pricing 
in  general.  As  a  result,  coverage  and  adequate  third-party  reimbursement  may  not  be  available  for  our  product  candidates  to 
enable us to realize an appropriate return on our investment in research and product development.

8

The  market  for  our  product  candidates  for  which  we  may  receive  regulatory  approval  will  depend  significantly  on 
access  to  third-party  payors’  drug  formularies,  or  lists  of  medications  for  which  third-party  payors  provide  coverage  and 
reimbursement.  The  industry  competition  to  be  included  in  such  formularies  often  leads  to  downward  pricing  pressures  on 
pharmaceutical companies. Also, third-party payors may refuse to include a particular branded drug in their formularies or may 
otherwise  restrict  patient  access  to  a  branded  drug  when  a  less  costly  generic  equivalent  or  other  alternative  is  available.  In 
addition,  because  each  third-party  payor  individually  approves  coverage  and  reimbursement  levels,  obtaining  coverage  and 
adequate  reimbursement  is  a  time-consuming  and  costly  process.  We  would  be  required  to  provide  scientific  and  clinical 
support for the use of any product to each third-party payor separately with no assurance that approval would be obtained, and 
we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the cost-effectiveness of our products. 
This process could delay the market acceptance of any of our product candidates for which we may receive approval and could 
have  a  negative  effect  on  our  future  revenue  and  operating  results.  We  cannot  be  certain  that  our  product  candidates  will  be 
considered  cost-effective.  If  we  are  unable  to  obtain  coverage  and  adequate  payment  levels  for  our  product  candidates  from 
third-party  payors,  physicians  may  limit  how  much  or  under  what  circumstances  they  will  prescribe  or  administer  them  and 
patients  may  decline  to  purchase  them.  This  in  turn  could  affect  our  ability  to  successfully  commercialize  our  products  and 
impact our profitability, results of operations, financial condition, and future success.

Human Capital Resources

Successful execution of our strategy is dependent on attracting, developing, and retaining key employees and members 
of  our  executive  leadership  team.  The  skills,  experience  and  industry  knowledge  of  our  employees  significantly  benefit  our 
operations  and  performance.  We  continuously  evaluate,  modify,  and  enhance  our  internal  processes  and  technologies  to 
increase  employee  engagement,  productivity,  and  efficiency.  The  Company  works  diligently  to  attract  the  best  talent  from  a 
diverse range of sources in order to meet the current and future demands of our business. We offer a strong employee value 
proposition  and  our  compensation  programs  are  designed  to  align  the  compensation  of  our  employees  with  the  Company’s 
performance and to provide the proper incentives to attract, retain and motivate employees. The structure of our compensation 
programs incentivizes both short-term and long-term performance and we believe in a total rewards experience, specifically:

• We provide employee wages that are competitive and consistent with employee positions, skill levels, experience, and 
knowledge. Our competitive benefits packages include equity grants such as stock options and restricted stock units; 
performance-based  bonuses;  recognition  awards;  an  employee  stock  purchase  plan;  retirement  savings  plan  with 
company  matching  contributions;  medical,  dental  and  life  insurance;  an  employee  assistance  program;  work/life 
balance arrangements, including core hours and flexible work arrangements; paid time off and holidays; and volunteer 
hours.

• We engage nationally recognized independent compensation and benefits consulting firms to evaluate the effectiveness 
of  our  executive  compensation  and  benefit  programs  and  to  provide  benchmarking  against  our  peers  within  the 
industry.

•

Annual  increases  and  incentive  compensation,  which  are  communicated  to  employees  at  the  time  of  hiring  and 
documented through our talent management process as part of our review procedures.

We also make significant investments in training, development and engagement, using development programs such as 
our Leadership Model Sessions program, comprised of interactive workshops to gain insight into leading at the Company, and 
our Mirati Mentor Program, in which employees self-nominate as mentors or mentees and facilitates meaningful relationships 
supporting new employees’ career and development goals.

As of December 31, 2021, we had 418 employees of which 413 were full-time, exempt employees, one was a part-
time, exempt employee, and the remaining were full-time, non-exempt employees. None of our employees are represented by a 
collective bargaining agreement

Culture

Fostering  and  maintaining  a  strong,  healthy  culture  is  fundamental  to  the  success  of  our  business.  Our  core  values 
reflect  who  we  are  and  the  way  our  employees  interact  with  one  another,  our  partners,  and  stakeholders.  Urgency,  open-
mindedness, accountability, and collaboration ground our work and behavior. These shared values are central to who we are, 
what we do, and how we do it. No matter the role, we are unified by our passion for helping patients, and we are inspired by a 
single  vision  –  to  unlock  the  science  behind  the  promise  of  a  life  beyond  cancer.  We  believe  our  culture  creates  strong 
engagement,  which  is  measured  through  an  annual  employee-wide,  anonymous  survey  to  assess  our  performance  on  metrics 
including mission and vision, development and empowerment, our ability to adapt and overall employee satisfaction. 

9

Diversity, Equity and Inclusion

We  believe  diverse  professional  experiences  and  an  inclusive  culture  can  drive  better  outcomes  for  patients.  Our 
culture is one where we challenge norms, have high risk tolerance and celebrate an entrepreneurial and courageous attitude full 
of grit and determination to make a difference. In 2021, we initiated a Diversity, Equity and Inclusion (“DE&I”) program, for 
which  we  took  the  following  initials  steps:  established  a  DE&I  Committee,  comprised  of  cross-functional  representatives 
including from medical affairs, supply chain, financial planning, business development, commercial and human resources, and 
surveyed all employees to inform the Company’s DE&I objectives and future employee training. Based on data as of November 
1, 2021, 46% of our Company’s employees identify as women, including 43% of our executive leadership team; and 40% of 
our Company’s employees identify as being a racial or ethnic minority, including 14% of our executive leadership team. As of 
December 31, 2021, 30% of the Company’s board of directors, identify as women and 30% identify as being a racial or ethnic 
minority. We are committed to diversifying the representation of our organization.

COVID-19 Health and Safety

We are committed to providing a healthy and safe work environment for our employees, partners and consultants. In 
early 2020 as the pandemic began, we assembled a cross-functional COVID-19 response team that included members of our 
executive  leadership.  At  the  start  of  the  pandemic,  we  quickly  moved  to  a  work-from-home  mandate  and  adopted  a  flexible 
work  schedule.  We  are  continuing  to  allow  for  flexible  work  schedules,  including  remote  and  hybrid  options.  To  allow 
employees  to  work  from  home  seamlessly,  we  provide  the  necessary  technology  and  collaboration  tools  and  developed  an 
internal task force to identify support opportunities for employees working from home and homeschooling children.

In  response  to  employee  feedback  and  as  part  of  our  commitment  to  supporting  our  employees  and  families  in 
meaningful  ways  throughout  the  pandemic,  we  put  in  place  the  following  programs:  a  work-from-home  stipend  for  all 
employees  whose  jobs  are  not  regularly  remote;  caregiver  resources,  including  a  tax-free  subsidy  to  help  with  unplanned 
dependent care costs; an Employee Assistance Program that includes free resources and confidential counseling for employees 
and their household members; and fully-covered COVID-19 testing for employees. 

As we move towards having more of our workforce onsite, we implemented the following protocols based on recent 
COVID-19  science  and  local/federal  government  advice:  requiring  the  COVID-19  vaccination  as  a  condition  to  be  at  our 
corporate  headquarters,  with  certain  exceptions;  Company  personnel  who  are  onsite  are  highly  recommended  to  wear  face 
masks  when  unable  to  physically  distance,  regardless  of  vaccination  status;  providing  disposable  masks;  face  masks  and  a 
negative COVID-19 test result are required for those who are unvaccinated for each week they are approved to come on-site; 
and all personnel complete a touch-free temperature check and “check” to the site via a third-party app to help keep track of 
employees  coming  to  the  site  for  potential  contact  tracing  needs.  We  continually  evaluate  our  approach  in  line  with  our 
principles to meet our company goals, while maintaining the well-being and productivity of our teams.

Item 1A.     Risk Factors

RISK FACTORS 

Risks Related to Our Business and Industry

Our research and development programs and product candidates are in development. As a result, we are unable to 

predict if or when we will successfully develop or commercialize our product candidates.

Our clinical-stage product candidates as well as our other pipeline assets will require significant further investment and 
regulatory approvals prior to commercialization. Adagrasib is in Phase 3 and Phase 1/2 clinical trials, sitravatinib is in a Phase 3 
clinical  trial,  and  Phase  1/2  clinical  trials,  MRTX1719  is  in  a  Phase  1  clinical  trial,  and  MRTX1133  is  in  preclinical 
development. We recently submitted an NDA to the FDA to adagrasib. Each of our product candidates will require the selection 
of  suitable  patients  for  our  clinical  trials  and  additional  clinical  development,  management  of  clinical,  preclinical  and 
manufacturing activities, obtaining regulatory approval, obtaining manufacturing supply, continued build out of a commercial 
organization, substantial investment and significant marketing efforts before we generate any revenues from product sales. We 
are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or 
comparable  foreign  regulatory  authorities,  and  we  may  never  receive  such  regulatory  approval  for  any  of  our  product 
candidates. The treatment of cancer is a rapidly evolving field and will continue to evolve.  By such time, if ever, as we may 
receive necessary regulatory approvals for our product candidates, the standard of care for the treatment of cancers may have 
evolved such that it would be necessary to modify our plans for full approval and commercial acceptance of our products may 
be  limited  by  a  change  in  the  standard  of  care.  In  addition,  some  of  our  product  development  programs  contemplate  the 
development  of  companion  diagnostics.  Companion  diagnostics  are  subject  to  regulation  as  medical  devices  and  we  or  our 
collaborators  may  be  required  to  obtain  marketing  approval  for  accompanying  companion  diagnostics  before  we  may 
commercialize our product candidates.

Even  if  we  obtain  the  required  financing  or  establish  a  collaboration  to  enable  us  to  conduct  late-stage  clinical 
development  of  our  product  candidates  and  pipeline  assets,  we  cannot  be  certain  that  such  clinical  development  would  be 
successful, or that we will obtain regulatory approval or be able to successfully commercialize any of our product candidates 
and  generate  revenue.  Success  in  preclinical  testing  and  early  clinical  trials  does  not  ensure  that  later  clinical  trials  will  be 
successful,  and  the  clinical  trial  process  may  fail  to  demonstrate  that  our  product  candidates  are  safe  and  effective  for  their 
proposed uses. Any such failure could cause us to abandon further development of any one or more of our product candidates 
and may delay development of other product candidates. Product candidates in later stages of clinical trials may fail to show the 
desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. Any delay in, or 
termination of, our clinical trials will delay and possibly preclude the submission of any new drug applications (“NDA”) with 
the FDA and, ultimately, our ability to commercialize our product candidates and generate product revenue.

We  recently  submitted  an  NDA  to  the  FDA.  We,  however,  have  not  previously  submitted  an  NDA  to  the  FDA,  or 
similar drug approval filings to comparable foreign authorities, for any product candidate, and we cannot be certain that any of 
our product candidates will receive regulatory approval. Further, our product candidates may not receive regulatory approval 
even if they are successful in clinical trials. If we do not receive regulatory approvals for our product candidates, we may not be 
able  to  continue  our  operations.  Even  if  we  successfully  obtain  regulatory  approvals  to  market  one  or  more  of  our  product 
candidates, our revenues will be dependent, in part, upon our current collaborators’ and future collaborators’ ability to obtain 
regulatory approval for the companion diagnostics to be used with our product candidates, if required, and upon the size of the 
markets in the territories for which we gain regulatory approval and have commercial rights. If the markets for patient subsets 
that  we  are  targeting  are  not  as  significant  as  we  estimate,  we  may  not  generate  significant  revenues  from  sales  of  such 
products, if approved.

Further, even if any product candidate we develop was to receive marketing approval or be commercialized for use in 
combination  with  other  existing  therapies,  we  would  continue  to  bear  the  risks  that  the  FDA  or  similar  foreign  regulatory 
authorities  could  revoke  approval  of  the  therapy  used  in  combination  with  our  product  candidate  or  that  safety,  efficacy, 
manufacturing or supply issues could arise with these existing therapies.

All of our product candidates are subject to extensive regulation, which can be costly and time consuming, cause 

delays or prevent approval of such product candidates for commercialization.

The clinical development of product candidates is subject to extensive regulation by the FDA in the United States and 
by comparable regulatory authorities in foreign markets. Product development is a very lengthy and expensive process, and its 
outcome is inherently uncertain. The product development timeline can vary significantly based upon the product candidate’s 
novelty and complexity and the applicable regulatory authority. For example, we are pursuing an expansion strategy to bring 

11

our leading product candidate to countries within the European Economic Area (“EEA”) and the United Kingdom (“UK”). The 
regulatory approval in other countries may include all the risks associated with FDA approval as well as additional, presently 
unanticipated,  risks.  Regulations  are  subject  to  change  and  regulatory  agencies  have  significant  discretion  in  the  approval 
process.

Numerous statutes and regulations govern human testing and the manufacture and sale of human therapeutic products 
in  the  United  States,  Europe  and  other  countries  and  regions  where  we  intend  to  market  our  products.  Such  legislation  and 
regulation  bears  upon,  among  other  things,  the  approval  of  trial  protocols  and  human  testing,  the  approval  of  manufacturing 
facilities, safety of the product candidates, testing procedures and controlled research, review and approval of manufacturing, 
preclinical and clinical data prior to marketing approval including adherence to good manufacturing practices (“GMP”) during 
production and storage as well as regulation of marketing activities including advertising and labeling.

In order to obtain regulatory approval, including an NDA or marketing authorization application, for the commercial 
sale  of  any  of  our  product  candidates  in  the  United  States,  EEA  and  other  foreign  market,  we  must  demonstrate  through 
preclinical  studies  and  clinical  trials,  as  well  as  extensive  information  regarding  chemistry,  manufacturing  and  controls 
(“CMC”), that the potential product is safe and effective for use in humans for each target indication. The failure to adequately 
demonstrate the safety and efficacy of a product under development could delay or prevent regulatory approval of our product 
candidates.  Regulatory  approval  in  one  country  does  not  ensure  regulatory  approval  in  another,  but  a  failure  or  delay  in 
obtaining regulatory approval in one country may negatively impact the regulatory process in others.

No  assurance  can  be  given  that  current  regulations  relating  to  regulatory  approval  will  not  change  or  become  more 
stringent in the United States or foreign markets. Regulatory agencies may also require that additional trials be run in order to 
provide additional information regarding the safety or efficacy of any drug candidates for which we seek regulatory approval or 
require  additional  administrative  review  periods,  including  obtaining  reimbursement  and  pricing  approval  in  select  markets. 
Moreover, any regulatory approval of a drug which is eventually obtained may entail limitations on the indicated uses for which 
that  drug  may  be  marketed.  Furthermore,  product  approvals  may  be  withdrawn  or  limited  in  some  way  if  problems  occur 
following  initial  marketing  or  if  compliance  with  regulatory  standards  is  not  maintained.  Regulatory  agencies  could  become 
more risk averse to any side effects or set higher standards of safety and efficacy prior to reviewing or approving a product. 
This  could  result  in  a  product  not  being  approved.  Any  of  the  foregoing  scenarios  could  materially  harm  the  commercial 
prospects for our product candidates.

The  successful  commercialization  of  our  product  candidates,  if  approved,  will  depend  on  achieving  market 

acceptance and we may not be able to gain sufficient acceptance to generate significant revenue.

Even if our product candidates are successfully developed and receive regulatory approval, they may not gain market 
acceptance among physicians, patients, healthcare payors such as private insurers or governments and other funding parties and 
the  medical  community.  The  degree  of  market  acceptance  for  any  of  our  products  will  depend  on  a  number  of  factors, 
including:

•

•

•

•

•

•

•

demonstration of the clinical efficacy and safety of our products;

the prevalence and severity of any adverse side effects;

limitations or warnings contained in the product’s approved labeling;

cost-effectiveness and availability of acceptable pricing;

competitive product profile versus alternative treatment methods and the superiority of alternative treatment or 
therapeutics;

the effectiveness of marketing and distribution methods and support for the products; and

the availability of coverage and adequate reimbursement from third-party payors to the extent that our products receive 
regulatory approval.

Disease  indications  may  be  small  subsets  of  a  disease  that  could  be  parsed  into  smaller  and  smaller  indications  as 
different subsets of diseases are defined. This increasingly fine characterization of diseases could have negative consequences; 
including  creating  an  approved  indication  that  is  so  small  as  not  to  have  a  viable  market  for  us.  If  future  technology  allows 
characterization of a disease in a way that is different from the characterization used for large pivotal studies, it may make those 

12

studies  invalid  or  reduce  their  usefulness,  and  may  require  repeating  all  or  a  portion  of  the  studies.  Future  technology  may 
supply better prognostic ability which could reduce the portion of patients projected to need a new therapy. Even after being 
cleared  by  regulatory  authorities,  a  product  may  later  be  shown  to  be  unsafe  or  not  to  have  its  purported  effect,  thereby 
preventing its widespread use or requiring withdrawal from the market.

We may not be successful in establishing development and commercialization collaborations which could adversely 

affect, and potentially prohibit, our ability to develop our product candidates.

Developing  pharmaceutical  products,  conducting  clinical  trials,  obtaining  regulatory  approval,  establishing 
manufacturing capabilities and marketing approved products is expensive, and therefore we may seek to enter into additional 
collaborations with companies that have more resources and experience in order to continue to develop and commercialize our 
product  candidates.  We  also  may  be  required  due  to  financial  or  scientific  constraints  to  enter  into  additional  collaboration 
agreements to research and/or to develop and commercialize our product candidates. The establishment and realization of such 
collaborations  may  not  be  possible  or  may  be  problematic.  There  can  be  no  assurance  that  we  will  be  able  to  establish  such 
additional collaborations on favorable terms, if at all, or that our current or future collaborative arrangements will be successful 
or maintained for any specific product candidate or indication. If we are unable to reach successful agreements with suitable 
collaboration partners for the ongoing development and commercialization of our product candidates, we may face increased 
costs, we may be forced to limit the scope and number of our product candidates we can commercially develop or the territories 
in which we commercialize such product candidates, and we may be unable to commercialize products or programs for which a 
suitable collaboration partner cannot be found. If we fail to achieve successful collaborations, our operating results and financial 
condition will be materially and adversely affected.

In  addition,  the  terms  of  any  collaboration  agreements  may  place  restrictions  on  our  activities  with  respect  to  other 
products,  including  by  limiting  our  ability  to  grant  licenses  or  develop  products  with  other  third  parties,  or  in  different 
indications,  diseases  or  geographical  locations,  or  may  place  additional  obligations  on  us  with  respect  to  development  or 
commercialization of our product candidates. If we fail to comply with or breach any provision of a collaboration agreement, a 
collaborator may have the right to terminate, in whole or in part, such agreement or to seek damages.

Some  of  our  collaboration  agreements,  including  the  BeiGene  Agreement  and  Zai  Agreement,  are  complex  and 
involve sharing or division of ownership of certain data, know-how and intellectual property rights among the various parties. 
Accordingly, our collaborators could interpret certain provisions differently than we or our other collaborators which could lead 
to unexpected or inadvertent disputes with collaborators. In addition, these agreements might make additional collaborations, 
partnering or mergers and acquisitions difficult.

There is no assurance that a collaborator who is acquired by a third party would not attempt to change certain contract 
provisions that could negatively affect our collaboration. The acquiring company may also not accept the terms or assignment 
of our contracts and may seek to terminate the agreements. Any one of our collaborators could breach covenants, restrictions 
and/or sub-license agreement provisions leading us into disputes and potential breaches of our agreements with other partners.

We have no experience in clinical or commercial manufacturing and depend on others for the production of our 
product  candidates  at  suitable  levels  of  quality  and  quantity.  Any  problems  or  delays  in  the  manufacture  of  our  products 
would have a negative impact on our ability to successfully execute our development and commercialization strategies.

We  do  not  currently  have  nor  do  we  plan  to  acquire  the  infrastructure  or  capability  internally  to  manufacture  our 
clinical drug supplies for use in the conduct of our clinical trials, and we lack the resources and the capability to manufacture 
any of our product candidates on a clinical or commercial scale. We rely on collaborators and/or third parties for development, 
scale-up, formulation, optimization, management of clinical trial and commercial scale manufacturing and commercialization. 
There  are  no  assurances  we  can  scale-up,  formulate  or  manufacture  any  product  candidate  in  sufficient  quantities  with 
acceptable specifications for the conduct of our clinical trials or for the regulatory agencies to grant approval of such product 
candidate. We have not yet commercialized any products and have no commercial manufacturing experience. To be successful, 
our products must be properly formulated, scalable, stable and safely manufactured in clinical trial and commercial quantities in 
compliance  with  GMP  and  other  regulatory  requirements  and  at  acceptable  costs.  Should  any  of  our  suppliers  or  our 
collaborators be unable to supply or be delayed in supplying us with sufficient supplies, no assurance can be given that we will 
be able to find alternative means of supply in a short period of time. Should such parties’ operations suffer a material adverse 
effect,  the  manufacturing  of  our  products  would  also  be  adversely  affected.  Furthermore,  key  raw  materials  could  become 
scarce or unavailable. There may be a limited number of third parties who can manufacture our products. We may not be able to 
meet specifications previously established for product candidates during scale-up and manufacturing.

13

Our reliance on third parties to manufacture our product candidates will expose us and our partners to risks including 
the following, any of which could delay or prevent the commercialization of our products, result in higher costs, or deprive us 
of potential product revenue:

•

•

•

Contract  manufacturers  can  encounter  difficulties  in  achieving  the  scale-up,  optimization,  formulation,  or  volume 
production  of  a  compound  as  well  as  maintaining  quality  control  with  appropriate  quality  assurance.  They  may  also 
experience  shortages  of  qualified  personnel.  Contract  manufacturers  are  required  to  undergo  a  satisfactory  GMP 
inspection  prior  to  regulatory  approval  and  are  obliged  to  operate  in  accordance  with  FDA,  International  Council  for 
Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (“ICH”), European and 
other  nationally  mandated  GMP  regulations  and/or  guidelines  governing  manufacturing  processes,  stability  testing, 
record keeping and quality standards. A failure of these contract manufacturers to follow GMP and to document their 
adherence  to  such  practices  or  failure  of  an  inspection  by  a  regulatory  agency  may  lead  to  significant  delays  in  the 
availability of our product candidate materials for clinical study, leading to delays in our trials.

For  each  of  our  current  product  candidates  we  will  initially  rely  on  a  limited  number  of  contract  manufacturers. 
Changing these or identifying future manufacturers may be difficult. Changing manufacturers requires re-validation of 
the  manufacturing  processes  and  procedures  in  accordance  with  FDA,  ICH,  European  and  other  mandated  GMP 
regulations and/or guidelines. Such re-validation may be costly and time-consuming. It may be difficult or impossible 
for us to quickly find replacement manufacturers on acceptable terms.

Our contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the 
time required to produce, store and distribute our products successfully.

A variety of risks associated with operating our business internationally could adversely affect our business.

In  addition  to  our  operations  in  the  United  States,  we  have  operations  in  the  Netherlands,  and  are  pursuing  further 
European  expansion  to  support  the  planned  commercialization  of  our  product  candidates  in  the  EEA  and  UK.  We  face  risks 
associated  with  our  international  operations,  including  possible  unfavorable  political,  tax  and  labor  conditions,  which  could 
harm our business. We are subject to numerous risks associated with international business activities, including:

•

•

•

•

•

•

•

•

•

•

difficulties in staffing and managing foreign operations;

foreign government taxes, regulations and permit requirements;

United  States  and  foreign  government  tariffs,  trade  restrictions,  price  and  exchange  controls  and  other  regulatory 
requirements;

anti-corruption laws, including the Foreign Corrupt Practices Act (“FCPA”);

economic weakness, including inflation, natural disasters, war, events of terrorism or political instability in particular 
foreign countries;

fluctuations in currency exchange rates, which could result in increased operating expenses and reduced revenues, and 
other obligations related to doing business in another country;

compliance  with  tax,  employment,  immigration  and  labor  laws,  regulations  and  restrictions  for  employees  living  or 
traveling abroad;

workforce uncertainty in countries where labor unrest is more common than in the United States;

production shortages resulting from any events affecting raw material supply or manufacturing capabilities aboard; and

changes in diplomatic and trade relationships.

Our business activities outside of the United States are subject to the FCPA and similar anti-bribery or anti-corruption 
laws, regulations or rules of other countries in which we operate. The FCPA and similar anti-corruption laws generally prohibit 
offering, promising, giving, or authorizing others to give anything of value, either directly or indirectly, to non-U.S. government 
officials in order to improperly influence any act or decision, secure any other improper advantage, or obtain or retain business. 
The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions 

14

of  the  company  and  to  devise  and  maintain  an  adequate  system  of  internal  accounting  controls.  As  described  above,  our 
business is heavily regulated and therefore involves significant interaction with public officials, including officials of non-U.S. 
governments. Additionally, in many other countries, the health care providers who prescribe pharmaceuticals are employed by 
their government, and the purchasers of pharmaceuticals are government entities; therefore, any dealings with these prescribers 
and purchasers may be subject to regulation under the FCPA. Recently the Securities and Exchange Commission (“SEC”) and 
the  U.S.  Department  of  Justice  (“DOJ”)  have  increased  their  FCPA  enforcement  activities  with  respect  to  pharmaceutical 
companies.  In  addition,  under  the  Dodd–Frank  Wall  Street  Reform  and  Consumer  Protection  Act,  private  individuals  who 
report to the SEC original information that leads to successful enforcement actions may be eligible for a monetary award. We 
are engaged in ongoing efforts that are designed to ensure our compliance with these laws, including due diligence, training, 
policies, procedures and internal controls. However, there is no certainty that all employees and third-party business partners 
(including  our  distributors,  wholesalers,  agents,  contractors,  and  other  partners)  will  comply  with  anti-bribery  laws.  In 
particular,  we  do  not  control  the  actions  of  manufacturers  and  other  third-party  agents,  although  we  may  be  liable  for  their 
actions.  Violation  of  these  laws  may  result  in  civil  or  criminal  sanctions,  which  could  include  monetary  fines,  criminal 
penalties, and disgorgement of past profits, which could have a material adverse impact on our business and financial condition.

We are or may become subject to tax audits in the Netherlands or other countries into which we expand our operations, 
and such jurisdictions may assess additional income tax against us. The final determination of tax audits could be materially 
different from our recorded income tax provisions and accruals. The ultimate results of an audit could have a material adverse 
effect on our operating results or cash flows in the period or periods for which that determination is made and could result in 
increases to our overall tax expense in subsequent periods.

These  and  other  risks  associated  with  our  international  operations  may  materially  adversely  affect  our  business, 

financial condition and results of operations.

The  COVID-19  pandemic  could  adversely  impact  our  business  including  our  ongoing  and  planned  clinical  trials 

and preclinical research.

Our business could be materially adversely affected by the effects of health epidemics. For example, since December 
2019, a novel strain of coronavirus, SARS-CoV-2, causing a disease referred to as COVID-19, has spread worldwide. In March 
2020,  the  World  Health  Organization  declared  the  COVID-19  outbreak  a  pandemic  and  the  U.S.  government-imposed  travel 
restrictions on travel between the U.S., Europe and certain other countries. In addition, the Governor of the State of California 
issued  a  number  of  stay-at-home  orders  and  health  directives.  As  a  result  of  such  orders,  we  implemented  work-from-home 
policies  for  most  of  our  employees  and  generally  suspended  business-related  travel.  Although  many  of  these  orders  and 
directives  have  since  been  lifted,  in  response  to  the  spread  of  various  variants  of  COVID-19  and  to  protect  the  health  and 
welfare of our employees, we continue to maintain flexible work-from-home policies for most of our employees. The effects of 
these work-from-home and travel policies have thus far had a limited impact on our business.

Our  business  could  be  materially  adversely  affected  by  health  epidemics  in  regions  where  we  or  our  partners  have 
concentrations of clinical trial sites or other business operations and could cause significant disruption in the operations of third-
party manufacturers and contract research organizations upon whom we rely. 

Quarantines, shelter-in-place, executive and similar government orders, or the perception that such orders, shutdowns 
or  other  restrictions  on  the  conduct  of  business  operations  could  occur,  could  impact  personnel  at  third-party  manufacturing 
facilities in the U.S. and other countries, or the availability or cost of materials, which would disrupt our supply chain. We have 
experienced impacts to our clinical trial operations due to the COVID-19 pandemic. Some examples of these impacts include:

•

•

•

•

we have experienced impact on clinical site initiation and patient enrollment due to restrictions imposed as a result of 
the COVID-19 pandemic; 

some patients have not been able to comply with clinical trial protocols as quarantines have impeded patient movement 
and interrupted healthcare services;

we have experienced some impact on our ability to recruit and retain patients and principal investigators and site staff 
who, as healthcare providers, may have heightened exposure to COVID-19; and

we  have  experienced  some  delays  in  necessary  interactions  with  regulators,  ethics  committees  and  other  important 
agencies  and  contractors  due  to  limitations  in  employee  resources  or  forced  furlough  of  government  or  contractor 
personnel.

15

The  global  COVID-19  pandemic  continues  to  rapidly  evolve.  While  we  have  not  yet  experienced  material  adverse 
effects  to  our  business  as  a  result  of  the  COVID-19  pandemic  the  ultimate  impact  of  the  COVID-19  pandemic  or  a  similar 
health epidemic is highly uncertain and could have negative impact our business, financial condition and operating results.

We rely upon third-party contractors and service providers for the execution of some aspects of our development 
programs.  Failure  of  these  collaborators  to  provide  services  of  a  suitable  quality  and  within  acceptable  timeframes  may 
cause the delay or failure of our development programs.

We  outsource  certain  functions,  tests  and  services  to  CROs,  medical  institutions  and  collaborators  and  outsource 
manufacturing  to  collaborators  and/or  contract  manufacturers,  and  we  rely  on  third  parties  for  quality  assurance,  clinical 
monitoring, clinical data management and regulatory expertise. In particular, we rely on CROs to run our clinical trials on our 
behalf  and  contract  manufacturers  to  manufacture  our  product  candidates.  There  is  no  assurance  that  such  individuals  or 
organizations  will  be  able  to  provide  the  functions,  tests,  drug  supply  or  services  as  agreed  upon  or  to  acceptable  quality 
standards, and we could suffer significant delays in the development of our products or processes. In particular, certain third 
party  service  providers  may  be  unable  to  comply  with  their  contractual  obligations  to  us  due  to  disruptions  caused  by  the  
COVID-19 pandemic, including reduced operations or headcount reductions, or otherwise, and in certain cases we may have 
limited recourse if the non-compliance is due to factors outside of the service provider’s control.

In some cases, there may be only one or few providers of such services, including manufacturing services. In addition, 
the cost of such services could increase significantly over time. We rely on third parties as mentioned above to enroll qualified 
patients and conduct, supervise and monitor our clinical trials. Our reliance on these third parties and collaborators for clinical 
development  activities  reduces  our  control  over  these  activities,  but  does  not  relieve  us  of  our  regulatory  responsibilities, 
including ensuring that our clinical trials are conducted in accordance with good clinical practices (“GCP”) regulations and the 
investigational  plan  and  protocols  contained  in  the  regulatory  agency  applications.  In  addition,  these  third  parties  may  not 
complete  activities  on  schedule  or  may  not  manufacture  compounds  under  GMP  conditions.  Preclinical  studies  may  not  be 
performed or completed in accordance with good laboratory practices, regulatory requirements or our trial design. If we or our 
CROs fail to comply with GCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and the 
FDA,  the  European  Medicines  Agency  (“EMA”)  or  comparable  foreign  regulatory  authorities  may  require  us  to  perform 
additional clinical trials before approving any marketing applications. If these third parties or collaborators do not successfully 
carry  out  their  contractual  duties  or  meet  expected  deadlines,  obtaining  regulatory  approval  for  manufacturing  and 
commercialization of our product candidates may be delayed or prevented. We rely substantially on third-party data managers 
for  our  clinical  trial  data.  There  is  no  assurance  that  these  third  parties  will  not  make  errors  in  the  design,  management  or 
retention of our data or data systems. There is no assurance that these third parties will pass FDA or regulatory audits, which 
could delay or prohibit regulatory approval.

Our CROs may also have relationships with other commercial entities, including our competitors, for whom they may 
also be conducting clinical trials or other product development activities, which could harm our competitive position. If any of 
our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs 
or  to  do  so  on  commercially  reasonable  terms.  Further,  switching  or  adding  additional  CROs  involves  additional  cost  and 
requires management time and attention. In addition, there is a natural transition period when a new CRO commences work. As 
a  result,  delays  may  occur,  which  could  materially  impact  our  ability  to  meet  our  desired  clinical  development  timelines. 
Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter challenges 
or  delays  in  the  future  or  that  these  delays  or  challenges  will  not  have  a  material  adverse  impact  on  our  business,  financial 
condition and prospects.

Competition  in  our  targeted  market  area  is  intense  and  this  field  is  characterized  by  rapid  technological  change. 
Therefore,  developments  by  competitors  may  substantially  alter  the  predicted  market  or  render  our  product  candidates 
uncompetitive.

We are aware of at least six companies who currently have competing commercial or clinical-stage direct KRAS G12C 
inhibitor  programs:  Amgen,  Inc.,  F.  Hoffman-LaRoche  Ltd.,  Eli  Lilly  and  Company,  Merck  &  Co.,  Inc,  Novartis  AG  and 
Boehringer Ingelheim International GmbH. 

There  are  several  immune  checkpoint  inhibitors  currently  approved  for  use  as  single  agents  to  treat  multiple  tumor 
types, including NSCLC.  To augment the efficacy of these agents, combination studies are being conducted with a variety of 
potentially synergistic mechanisms, including inhibitors of CTLA-4, LAG3, TIM-3, TIGIT and CSF-1R, among others. Most of 
these  combination  studies  are  being  conducted  in  patients  who  are  naïve  to  immune  checkpoint  inhibitor  therapy.  Direct 
mechanistic competitors to sitravatinib in combination with checkpoint inhibitors in NSCLC patients who had previously failed 
checkpoint inhibitor therapy include CABOMETYX® (Exelixis, Inc.) and LENVIMA® (Eisai Co., Ltd.), both anti-VEGF agents 

16

that  also  inhibit  other  receptor  tyrosine  kinases.  Additionally,  there  are  numerous  other  potential  competitors  with  kinase 
inhibitors  that  are  being  evaluated  in  combination  with  checkpoint  inhibitors  in  NSCLC  patients  who  had  previously  failed 
checkpoint inhibitor therapy in earlier lines of treatment.

In addition to companies that have inhibitors addressing our targets of interest, our competition also includes hundreds 
of private and publicly traded companies that operate in the area of oncology but have therapeutics with different mechanisms 
of action.  The oncology market in general is highly competitive with over 1,000 molecules currently in clinical development. 
Other important competitors, in addition to those mentioned above, are small and large biotechnology companies, specialty and 
regional  pharmaceutical  companies  and  multinational  pharmaceutical  companies,  including  but  not  limited  to  AbbVie  Inc., 
AstraZeneca plc, Bristol-Myers Squibb Company, Gilead Sciences, Inc., GlaxoSmithKline plc, Johnson & Johnson, Pfizer Inc., 
Sanofi S.A., and Takeda Pharmaceutical Co.

Developments by others may render our products or technologies non-competitive or we may not be able to keep pace 
with technological developments. Our competitors may have developed or may be developing technologies which may be the 
basis  for  competitive  products.  Some  of  these  products  may  prove  to  be  more  effective  and  less  costly  than  the  products 
developed or being developed by us. Our competitors may obtain regulatory approval for their products more rapidly than we 
do  which  may  change  the  standard  of  care  in  the  indications  we  are  targeting,  rendering  our  technology  or  products  non-
competitive. For example, with the recent approval of immunotherapy agents for the treatment of NSCLC and other cancers, the 
standard of care for the treatment of cancer is evolving and will continue to evolve which could require us to change the design 
and  timelines  for  our  registration  trials  and  may  limit  the  commercial  acceptance  of  our  products  in  the  future.  Others  may 
develop treatments or cures superior to any therapy we are developing or will develop. Moreover, alternate, less toxic forms of 
medical treatment may be developed which may be competitive with our products.

Many  of  the  organizations  which  could  be  considered  to  be  our  competitors  have  substantially  more  financial  and 
technical  resources,  more  extensive  discovery  research,  preclinical  research  and  development  capabilities  and  greater 
manufacturing,  marketing,  distribution,  production  and  human  resources  than  we  do.  Many  of  our  current  or  potential 
competitors  have  more  experience  than  we  do  in  research,  preclinical  testing  and  clinical  trials,  drug  commercialization, 
manufacturing  and  marketing,  and  in  obtaining  domestic  and  foreign  regulatory  approvals.  In  addition,  failure,  unacceptable 
toxicity, lack of sales or disappointing sales or other issues regarding competitors’ products or processes could have a material 
adverse effect on our product candidates, including our clinical candidates or our lead compounds. Established pharmaceutical 
companies may invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds 
that could make our product candidates less competitive. In addition, any new product that competes with an approved product 
must  demonstrate  compelling  advantages  in  efficacy,  convenience,  tolerability  and  safety  in  order  to  overcome  price 
competition and brand recognition and to be commercially successful. Accordingly, our competitors may succeed in obtaining 
patent  protection,  receiving  FDA,  EMA  or  other  regulatory  approval  or  discovering,  developing  and  commercializing 
medicines before we do, which would have a material adverse impact on our business.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their 
regulatory  approval,  limit  the  commercial  profile  of  an  approved  product  label,  or  result  in  significant  negative 
consequences following marketing approval, if any.

Undesirable side effects 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 other 
comparable  foreign  authorities.  Results  of  our  trials  could  reveal  a  high  and  unacceptable  severity  and  prevalence  of  side 
effects. In such an event, our trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities 
could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. 
Treatment-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial, or result in 
potential  product  liability  claims.  Any  of  these  occurrences  may  harm  our  business,  financial  condition  and  prospects 
significantly.

Additionally,  if  one  or  more  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 approvals of such product;

regulatory authorities may require additional warnings on the product label;

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

17

•

•

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

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of any product candidate, if 

approved, and could significantly harm our business, results of operations and prospects.

We are subject to competition for our skilled personnel and may experience challenges in identifying and retaining 

key personnel that could impair our ability to conduct our operations effectively.

Our future success depends on our ability to retain our executive officers and to attract, retain and motivate qualified 
personnel. If we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully 
implement  our  business  strategy.  Although  we  have  not  experienced  problems  attracting  and  retaining  highly  qualified 
personnel in the recent past, our industry has experienced a high rate of turnover of management personnel in recent years. Our 
ability to compete in the highly competitive biotechnology and pharmaceuticals industries depends upon our ability to attract 
and  retain  highly  qualified  managerial,  scientific  and  medical  personnel.  We  are  highly  dependent  on  our  management, 
scientific  and  medical  personnel,  whose  services  are  critical  to  the  successful  implementation  of  our  product  candidates, 
development and regulatory strategies, as well as the management of our financial operations. We are not aware of any present 
intention of any of these personnel to leave our Company. In order to induce valuable employees to continue their employment 
with us, we have provided equity awards that vest over time. The value to employees of equity awards that vest over time is 
significantly  affected  by  movements  in  our  stock  price  that  are  beyond  our  control,  and  may  at  any  time  be  insufficient  to 
counteract more lucrative offers from other companies.

Despite our efforts to retain valuable employees, members of our management, scientific and development teams may 
terminate their employment with us at any time, with or without notice. The loss of the services of any of our executive officers 
or  other  key  employees  and  our  inability  to  find  suitable  replacements  could  harm  our  business,  financial  condition  and 
prospects. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level and 
senior managers as well as junior, mid-level and senior scientific and medical personnel.

We will continue to experience growth in the number of our employees and the scope of our operations. This growth 
will place a significant strain on our management, operations and financial resources and we may have difficulty managing this 
future potential growth. No assurance can be provided that we will be able to attract new employees to assist in our growth. 
Many of the other pharmaceutical companies that we compete against for qualified personnel have greater financial and other 
resources, different risk profiles and a longer history in the industry than we do. We also may employ consultants or part-time 
and contract employees. There can be no assurance that these individuals are retainable. While we have been able to attract and 
retain skilled and experienced personnel and consultants in the past, no assurance can be given that we will be able to do so in 
the future.

We have attempted to obtain FDA approval of adagrasib, sitravatinib or other product candidates through the use 
of the accelerated approval pathway. If we are unable to obtain such approval, we may be required to await the completion 
of planned or ongoing clinical trials or conduct additional clinical trials, which could increase the expense of obtaining, and 
delay the receipt of, necessary approval. 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 
accelerated approval.

We  may  in  the  future  seek  an  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  usually  contingent  on  the 
sponsor’s agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify and describe the 

18

drug’s  clinical  benefit.  If  such  post-approval  studies  fail  to  confirm  the  drug’s  clinical  benefit,  the  FDA  may  withdraw  its 
approval of the drug.

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. If we decide to submit 
an  application  for  accelerated  approval  for  our  product  candidates,  there  can  be  no  assurance  that  such  submission  or 
application will be accepted or that review or approval will be granted on a timely basis, or at all. A failure to obtain accelerated 
approval  would  result  in  a  longer  time  period  to  commercialization  of  such  product  candidate,  could  increase  the  cost  of 
development of such product candidate and could harm our competitive position in the marketplace.

If  we  or  third  parties  are  unable  to  successfully  develop  companion  diagnostics  for  our  product  candidates,  or 
experience significant delays in doing so, we may not achieve marketing approval or realize the full commercial potential of 
such product candidates.

A key part of our development strategy for our product candidates is to identify subsets of patients with specific types 
of  tumors  that  express  specific  genetic  markers.  Identification  of  these  patients  will  require  the  use  and  development  of 
companion diagnostics. The FDA generally will either require approval or clearance of the diagnostic at the same time the FDA 
approves the therapeutic product, or as a post-marketing commitment at the time of the therapeutic product’s approval. We do 
not have experience or capabilities in developing or commercializing diagnostics and plan to rely in large part on third parties to 
perform these functions. 

Companion diagnostics are subject to regulation by the FDA and comparable foreign regulatory authorities as medical 
devices  and  will  likely  require  separate  regulatory  approval  prior  to  commercialization.  If  we  or  third  parties  are  unable  to 
successfully develop companion diagnostics for our product candidates, or experience delays in doing so:

•

•

•

the  development  of  these  product  candidates  may  be  delayed  because  it  may  be  difficult  to  identify  patients  for 
enrollment in our clinical trials in a timely manner;

these product candidates may not receive marketing approval if their safe and effective use depends on a companion 
diagnostic; and

we may not realize the full commercial potential of these product candidates that receive marketing approval if, among 
other reasons, we are unable to appropriately identify patients or types of tumors with the specific genetic alterations 
targeted by these product candidates.

Even  if  our  product  candidates  and  any  associated  companion  diagnostics  are  approved  for  marketing,  the  need  for 
companion diagnostics may slow or limit adoption of our product candidates. Although we believe genetic testing is becoming 
more  prevalent  in  the  diagnosis  and  treatment  of  cancer,  our  product  candidates  may  be  perceived  negatively  compared  to 
alternative treatments that do not require the use of companion diagnostics, either due to the additional cost of the companion 
diagnostic  or  the  need  to  complete  additional  procedures  to  identify  genetic  markers  prior  to  administering  our  product 
candidates.

If any of these events were to occur, our business and growth prospects would be harmed, possibly materially.

Interim, topline and preliminary data from our clinical trials may change as more patient data become available, 

and are subject to audit and verification procedures that could result in material changes in the final data.

From  time  to  time,  we  may  publicly  disclose  preliminary,  interim  or  topline  data  from  our  preclinical  studies  and 
clinical  trials,  which  is  based  on  a  preliminary  analysis  of  then-available  data,  and  the  results  and  related  findings  and 
conclusions  are  subject  to  change  as  patient  enrollment  and  treatment  continues  and  more  patient  data  become  available. 
Adverse differences between previous preliminary or interim data and future interim or final data could significantly harm our 
business prospects. We may also announce topline data following the completion of a preclinical study or clinical trial, which 
may be 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 interim, topline or preliminary results that we report 
may  differ  from  future  results  of  the  same  studies,  or  different  conclusions  or  considerations  may  qualify  such  results,  once 
additional data have been received and fully evaluated. Preliminary, interim, or topline data also remain subject to audit and 

19

verification procedures that may result in the final data being materially different from the data we previously published. As a 
result, preliminary, interim, and topline data should be viewed with caution until the final data are available.

Further, 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 our company in 
general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what 
is  typically  extensive  information,  and  you  or  others  may  not  agree  with  what  we  determine  to  be  material  or  otherwise 
appropriate information to include in our disclosure.

The timelines of our clinical trials may be impacted by numerous factors and any delays may adversely affect our 

ability to execute our current business strategy.

Clinical testing is expensive, difficult to design and implement, can take many years to complete, and is uncertain as to 
outcome. We may experience delays in clinical trials at any stage of development and testing of our product candidates. Our 
planned clinical trials may not begin on time, have an effective design, enroll a sufficient number of subjects, or be completed 
on schedule, if at all.

Events which may result in a delay or unsuccessful completion of clinical trials include:

inability to raise funding necessary to initiate or continue a trial;

delays in obtaining regulatory approval to commence a trial;

delays in reaching agreement with the FDA or other regulatory authorities on final trial design;

imposition of a clinical hold following an inspection of our clinical trial operations or trial sites by the FDA or other 
regulatory authorities;

delays in reaching agreement on acceptable terms with prospective CROs and clinical trial sites;

delays in obtaining required institutional review board approval at each site;

delays in having subjects complete participation in a trial or return for post-treatment follow-up;

delays caused by subjects dropping out of a trial due to side effects or otherwise;

delays caused by or relating to the COVID-19 pandemic;

clinical sites dropping out of a trial to the detriment of enrollment;

time required to add new clinical sites; and

delays by our contract manufacturers to produce and deliver a sufficient supply of clinical trial materials.

•

•

•

•

•

•

•

•

•

Furthermore, enrollment may depend on the availability of suitable companion diagnostics to identify genetic markers 

we are targeting and the capability and willingness of clinical sites to conduct genetic screening of potential patients.

If  initiation  or  completion  of  any  of  our  clinical  trials  for  our  product  candidates  are  delayed  for  any  of  the  above 
reasons  or  for  other  reasons,  our  development  costs  may  increase,  our  approval  process  could  be  delayed,  any  periods  after 
commercial launch and before expiration of patent protection may be reduced and our competitors may have more time to bring 
products  to  market  before  we  do.  Any  of  these  events  could  impair  the  commercial  potential  of  our  product  candidates  and 
could have a material adverse effect on our business.

If we experience delays or difficulties in the enrollment of patients in clinical trials, those clinical trials could take 

longer than expected to complete and our receipt of necessary regulatory approvals could be delayed or prevented.

We  may  not  be  able  to  initiate  or  complete  clinical  trials  for  our  product  candidates  if  we  are  unable  to  locate  and 
enroll a sufficient number of eligible patients to participate in these trials. In particular, because we are focused on patients with 

20

specific genetic alterations in some of our trials, our pool of suitable patients may be smaller and more selective and our ability 
to  enroll  a  sufficient  number  of  suitable  patients  may  be  limited  or  take  longer  than  anticipated.  In  addition,  some  of  our 
competitors have ongoing clinical trials for product candidates that treat the same indications, including NSCLC, where we are 
studying  adagrasib  in  monotherapy  and  in  combination  with  other  anticancer  therapies,  and  sitravatinib  in  combination  with 
checkpoint inhibitors, or target the same genetic alterations as our product candidates. Therefore, patients who would otherwise 
be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates.

Patient enrollment for any of our clinical trials may also be affected by other factors, including without limitation:

•

•

•

•

•

•

•

•

•

the severity of the disease under investigation

the frequency of the genetic alteration we are seeking to target in the applicable trial, and the ability to effectively 
identify such alteration;

the willingness of clinical sites and principal investigators to subject candidate patients to genetic screening;

the eligibility criteria for the study in question;

the perceived risks and benefits of the product candidate under study;

the availability, effectiveness and safety of other treatment options;

the patient referral practices of physicians;

the ability to monitor patients adequately during and after treatment; and

the proximity and availability of a sufficient number of clinical trial sites that are willing to comply with the 
requirements of our clinical protocols.

For  example,  due  to  the  targeted  indications  and  patient  populations  we  intend  to  focus  on  for  development  of  our 
product candidates, the number of study sites and patient populations available to us may be limited, and therefore enrollment 
of suitable patients to participate in clinical trials for these product candidates may take longer than would be the case if we 
were pursuing broader indications or patient populations.

We  are  and  continue  to  be  subject  to  stringent  government  regulations  concerning  the  clinical  testing  of  our 

products. We will also continue to be subject to government regulation of any product that receives regulatory approval.

Numerous statutes and regulations govern human testing and the manufacture and sale of human therapeutic products 
in  the  United  States,  EEA,  UK  and  other  countries  where  we  intend  to  market  our  products.  Such  legislation  and  regulation 
bears  upon,  among  other  things,  the  approval  of  trial  protocols  and  human  testing,  the  approval  of  manufacturing  facilities, 
testing procedures, CMC and controlled research, the review and approval of manufacturing, preclinical and clinical data prior 
to  marketing  approval,  including  adherence  to  GMP  during  production  and  storage,  and  marketing  activities  including 
advertising and labeling.

Clinical trials may be delayed or suspended at any time by us or by the FDA or other similar regulatory authorities if it 
is determined at any time that patients may be or are being exposed to unacceptable health risks, including the risk of death, or 
if compounds are not manufactured under acceptable GMP conditions or with acceptable quality. Current regulations relating to 
regulatory approval may change or become more stringent. The agencies may also require additional trials be run in order to 
provide  additional  information  regarding  the  safety,  efficacy  or  equivalency  of  any  product  candidate  for  which  we  seek 
regulatory approval.

Moreover, any regulatory approval of a drug which is eventually obtained may entail limitations on the indicated uses 
for  which  that  drug  may  be  marketed  or  on  the  conditions  of  approval,  or  contain  requirements  for  potentially  costly  post-
marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. 
These  requirements  include  submissions  of  safety  and  other  post-marketing  information  and  reports,  registration,  as  well  as 
continued compliance with GMPs and GCPs for any clinical trials that we conduct post-approval. In addition, if the FDA or a 
comparable  foreign  regulatory  authority  approves  any  of  our  product  candidates,  the  manufacturing  processes,  labeling, 
packaging,  distribution,  adverse  event  reporting,  storage,  advertising,  promotion  and  recordkeeping  for  the  product  will  be 
subject  to  extensive  and  ongoing  regulatory  requirements.  For  example,  prescription  drugs  may  be  promoted  only  for  the 

21

approved  indications  in  accordance  with  the  approved  label.  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  liability.  However,  physicians  may,  in  their  independent  medical  judgment,  prescribe  legally 
available products for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments, but the 
FDA  does  restrict  manufacturer’s  communications  on  the  subject  of  off-label  use  of  their  products.  Furthermore,  product 
approvals  may  be  withdrawn  or  limited  in  some  way  if  problems  occur  following  initial  marketing  or  if  compliance  with 
regulatory standards is not maintained. Similar restrictions are imposed in foreign markets. Regulatory agencies could become 
more risk averse to any side effects or set higher standards of safety and efficacy prior to reviewing or approving a product. 
This could result in a product not being approved.

If  we,  or  any  future  marketing  collaborators  or  contract  manufacturers,  fail  to  comply  with  applicable  regulatory 
requirements,  we  may  be  subject  to  sanctions  including  fines,  product  recalls  or  seizures  and  related  publicity  requirements, 
injunctions, total or partial suspension of production, civil penalties, suspension or withdrawals of previously granted regulatory 
approvals,  warning  or  untitled  letters,  refusal  to  approve  pending  applications  for  marketing  approval  of  new  products  or  of 
supplements  to  approved  applications,  import  or  export  bans  or  restrictions,  and  criminal  prosecution  and  penalties.  Any  of 
these penalties could delay or prevent the promotion, marketing or sale of our products and product candidates.

The FDA’s policies, and policies of comparable foreign regulatory authorities, 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 to adopt 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,  which  would  adversely  affect  our 
business, prospects and ability to achieve or sustain profitability.

Breakthrough therapy designation by the FDA, even if granted for any of our product candidates, may not lead to a 
faster  development  or  regulatory  review  or  approval  process  and  it  does  not  increase  the  likelihood  that  our  product 
candidates will receive marketing approval.

We received breakthrough therapy designation for adagrasib for the treatment of patients with NSCLC with the KRAS 
G12C  mutation  following  prior  systemic  therapy,  and  we  may  seek  breakthrough  therapy  designation  for  future  product 
candidates. A breakthrough therapy is defined as a drug or biologic that is intended, alone or in combination with one or more 
other drugs or biologics, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates 
that  the  drug,  or  biologic,  may  demonstrate  substantial  improvement  over  existing  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, sponsors may obtain more frequent interaction with and communication with 
the FDA to help to identify the most efficient path for clinical development.

The  receipt  of  a  breakthrough  therapy  designation  for  a  product  candidate  may  not  result  in  a  faster  development 
process, review or approval and does not change the approval standards or assure ultimate approval by the FDA. In addition, 
the FDA may later decide that the product no longer meets the conditions for qualification. As such, there can be no assurance 
that  even  if  we  do  receive  breakthrough  therapy  designation,  that  such  designation  will  have  a  material  impact  on  our 
development program.

The failure to (i) maintain the BeiGene Agreement or the failure of BeiGene to perform its obligations under the 
BeiGene Agreement and/or (ii) maintain the Zai Agreement or the failure of Zai to perform its obligations under the Zai 
Agreement, could, in each case, negatively impact our business.

Pursuant to the terms of the BeiGene Agreement, we granted to BeiGene an exclusive license to develop, manufacture 
and  commercialize  sitravatinib  in  the  BeiGene  Licensed  Territory.  Consequently,  our  ability  to  generate  any  revenues  from 
sitravatinib  in  the  BeiGene  Licensed  Territory  depends  on  our  ability  to  maintain  our  collaboration  with  BeiGene.  We  have 
limited control over the amount and timing of resources that BeiGene will dedicate to these efforts.

Pursuant to the terms of the Zai Agreement, we granted Zai the right to research, develop, manufacture and exclusively 
commercialize adagrasib in the Zai Licensed Territory. Consequently, our ability to generate any revenues from adagrasib in the 
Zai Licensed Territory depends on our ability to maintain our collaboration with Zai. We have limited control over the amount 
and timing of resources that Zai will dedicate to these efforts.

We are subject to a number of other risks associated with our dependence on the BeiGene Agreement with respect to 
sitravatinib in the BeiGene Licensed Territory and the Zai Agreement with respect to adagrasib in the Zai Licensed Territory, 
including:

22

•

•

•

BeiGene or Zai may not comply with applicable regulatory guidelines with respect to developing, manufacturing or 
commercializing sitravatinib or adagrasib, respectively, which could adversely impact sales or future development of 
sitravatinib in or outside of the BeiGene Licensed Territory or adagrasib in or outside of the Zai Licensed Territory, 
respectively;

There may be disputes between us and BeiGene or Zai, including disagreements regarding the BeiGene Agreement or 
the Zai Agreement, respectively; and

BeiGene or Zai may not properly 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 rights or expose us to 
potential litigation.

Each of the BeiGene Agreement and Zai Agreement are also subject to early termination, including through BeiGene’s 
and Zai’s (as applicable) right to terminate without cause upon advance notice to us. If the agreement is terminated early, we 
may not be able to find another collaborator for the further development and commercialization of (i) with respect to BeiGene, 
sitravatinib in the BeiGene Licensed Territory and/or (ii) with respect to Zai, adagrasib in the Zai Licensed Territory, in each 
case  on  acceptable  terms,  or  at  all,  and  we  may  be  unable  to  pursue  continued  development  and  commercialization  of 
sitravatinib in the BeiGene Licensed Territory and/or adagrasib in the Zai Licensed Territory on our own.

If we fail to obtain coverage and adequate reimbursement for our products, our revenue-generating ability will be 

diminished and there is no assurance that the anticipated market for our products will be sustained.

We believe that there will be many different applications for products successfully derived from our technologies and 
that the anticipated market for products under development will continue to expand. However, due to competition from existing 
or new products and the yet-to-be established commercial viability of our products, no assurance can be given that these beliefs 
will prove to be correct. Physicians, patients, formularies, payors or the medical community in general may not accept or utilize 
any products that we or our collaborative partners may develop. Other drugs may be approved during our clinical testing which 
could change the accepted treatments for the disease targeted and make our product candidates obsolete.

Our  and  our  collaborators’  ability  to  commercialize  our  products  successfully  will  depend,  in  part,  on  the  extent  to 
which  coverage  and  adequate  reimbursement  for  such  products  and  related  treatments  will  be  available  from  governmental 
health payor programs at the federal and state levels, including Medicare and Medicaid, private health insurers, managed care 
plans and other organizations. No assurance can be given that third-party payor coverage and adequate reimbursement will be 
available that will allow us to maintain price levels sufficient for the realization of an appropriate return on our investment in 
product development.

Coverage and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and 
private health insurers, managed care plans and other organizations is critical to new product acceptance. There is no uniform 
coverage  and  reimbursement  policy  among  third-party  payors  in  the  United  States;  however,  private  third-party  payors  often 
follow  Medicare  coverage  policy  and  payment  limitations  in  setting  their  own  reimbursement  rates.  Additionally,  coverage 
decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower 
cost therapeutic alternatives are already available or subsequently become available. Even if we obtain coverage for our product 
candidates,  the  resulting  reimbursement  payment  rates  might  not  be  adequate  or  may  require  co-payments  that  patients  find 
unacceptably  high.  Patients  are  unlikely  to  use  our  product  candidates  unless  coverage  is  provided  and  reimbursement  is 
adequate to cover a significant portion of the cost of our product candidates.

Additionally, we or our collaborators may develop companion diagnostic tests for use with our product candidates. We 
or our collaborators will be required to obtain coverage and reimbursement for these tests separate and apart from the coverage 
and  reimbursement  we  seek  for  our  product  candidates,  once  approved.  While  we  have  not  yet  developed  any  companion 
diagnostic  test  for  use  with  our  product  candidates,  if  we  do,  there  is  significant  uncertainty  regarding  our  ability  to  obtain 
coverage and adequate reimbursement for the same reasons applicable to our product candidates.

In  the  United  States  and  in  many  other  countries,  pricing  and/or  profitability  of  some  or  all  prescription 
pharmaceuticals and biopharmaceuticals are subject to varying degrees of government control.  In the United States, there has 
recently  been  increased  government  enforcement  and  government  and  payor  scrutiny  relating  to  drug  pricing  and  price 
increases.  For example, there have been several recent U.S. Congressional inquiries and proposed and enacted federal and state 
legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing 
and  manufacturer  patient  programs,  and  reform  government  program  reimbursement  methodologies  for  drugs.  At  the  federal 

23

level,  the  Trump  administration  used  several  means  to  propose  implementing  drug  pricing  reform,  including  through  federal 
budget  proposals,  executive  orders  and  policy  initiatives.  For  example,  on  July  24,  2020  and  September  13,  2020,  President 
Trump signed several executive orders aimed at lowering drug prices. As a result, the FDA released a final rule and guidance in 
September  2020  providing  pathways  for  states  to  build  and  submit  importation  plans  for  drugs  from  Canada.  Further,  on 
November 20, 2020, the U.S. Department of Health and Human Services (“HHS”) finalized a regulation removing safe harbor 
protection  for  price  reductions  from  pharmaceutical  manufacturers  to  plan  sponsors  under  Part  D,  either  directly  or  through 
pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by 
the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new 
safe harbor for price reductions reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements 
between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed until January 1, 
2023. On November 20, 2020, Centers for Medicare & Medicaid Services (“CMS”) issued an interim final rule implementing 
President  Trump’s  Most  Favored  Nation  executive  order,  which  would  tie  Medicare  Part  B  payments  for  certain  physician-
administered drugs to the lowest price paid in other economically advanced countries. As a result of litigation challenging the 
Most Favored Nation model, on December 27, 2021, CMS published a final rule that rescinded the Most Favored Nation model 
interim final rule. In July 2021, the Biden administration released an executive order, “Promoting Competition in the American 
Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, 
HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets 
out  a  variety  of  potential  legislative  policies  that  Congress  could  pursue  to  advance  these  principles.  No  legislation  or 
administrative actions have been finalized to implement these principles. In addition, Congress is considering drug pricing as 
part of other reform initiatives. At the state level, legislatures have 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. These changes may adversely impact the prices 
we or our future collaborators may charge for our products candidates, if commercialized.

Outside of the United States, the successful commercialization of our products will depend largely on obtaining and 
maintaining  government  coverage,  because  in  many  countries,  patients  are  unlikely  to  use  prescription  drugs  that  are  not 
covered by their government healthcare programs. Negotiating coverage and reimbursement with governmental authorities can 
delay commercialization by 12 months or more. Coverage and reimbursement policies may adversely affect our ability to sell 
our  products  on  a  profitable  basis.  In  many  international  markets,  governments  control  the  prices  of  prescription 
pharmaceuticals, including through the implementation of reference pricing, price cuts, rebates, revenue-related taxes and profit 
control, and we expect prices of prescription pharmaceuticals to decline over the life of the product or as volumes increase.

Healthcare reform and controls on healthcare spending may limit the price we charge for any products and the amounts 
thereof that we can sell. In particular, in the United States, the federal government and private insurers have changed, and have 
considered ways to change, the manner in which healthcare services are provided. In March 2010, the Patient Protection and 
Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, “ACA”) became law in 
the  United  States.  With  respect  to  pharmaceutical  products,  the  ACA,  among  other  things,  expanded  and  increased  industry 
rebates  for  drugs  covered  by  Medicaid  and  made  changes  to  the  coverage  requirements  under  Medicare  Part  D,  Medicare’s 
prescription drug benefits program. Some of the provisions of the ACA have yet to be fully implemented, and there have been 
executive,  judicial  and  Congressional  challenges  to  certain  aspects  of  the  ACA.  For  example,  on  June  17,  2021  the  U.S. 
Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the 
“individual mandate” was repealed by Congress. Thus, the ACA will remain in effect in its current form. Further, prior to the 
U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive order that initiated a special enrollment 
period 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, 
including  among  others,  reexamining  Medicaid  demonstration  projects  and  waiver  programs  that  include  work  requirements, 
and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It 
is  possible  that  the  ACA  will  be  subject  to  judicial  or  Congressional  challenges  in  the  future.  It  is  unclear  how  any  such 
challenges and the health reform measures of the Biden administration will impact the ACA and our business.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. In August 2011, 
the  Budget  Control  Act  of  2011,  among  other  things,  created  measures  for  spending  reductions  by  Congress.  A  Joint  Select 
Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 
2013  through  2021,  was  unable  to  reach  required  goals,  thereby  triggering  the  legislation’s  automatic  reduction  to  several 
government programs. These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal 
year, which went into effect on April 1, 2013 and, as amended by subsequent legislation including the Bipartisan Budget Act of 
2018, will stay in effect through 2030, except for a temporary suspension from May 1, 2020 through March 31, 2022 due to the 
COVID-19  pandemic,  unless  additional  Congressional  action  is  taken.  Under  current  legislation,  the  actual  reduction  in 

24

Medicare  payments  will  vary  from  1%  in  2022  to  up  to  3%  in  the  final  fiscal  year  of  this  sequester.  On  March  11,  2021, 
President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate 
cap,  currently  set  at  100%  of  a  drug’s  average  manufacturer  price,  for  single  source  and  innovator  multiple  source  drugs, 
beginning  January  1,  2024.  In  January  2013,  President  Obama  signed  into  law  the  American  Taxpayer  Relief  Act  of  2012, 
which,  among  other  things,  further  reduced  Medicare  payments  to  several  types  of  providers  and  increased  the  statute  of 
limitations period for the government to recover overpayments to providers from three to five years. These laws may result in 
additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on our customers 
and accordingly, our financial operations.

We anticipate that the ACA, as well as alternative or replacement healthcare reform measures that may be adopted in 
the  future,  may  result  in  more  rigorous  coverage  criteria  and  additional  downward  pressure  on  the  reimbursement  we  may 
receive for any approved product. It is possible that additional governmental action will be taken in response to the COVID-19 
pandemic. Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives.

In  addition,  levels  of  reimbursement  may  be  impacted  by  other  current  and  future  legislation,  regulation  or 
reimbursement  policies  of  third-party  payors  in  a  manner  that  may  harm  the  demand  and  reimbursement  available  for  our 
products, including for companion diagnostics for our products, which in turn, could harm our future product pricing and sales. 
Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments 
from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being 
able to generate revenue, attain profitability or commercialize our products.

Our potential future relationships with customers and third-party payors in the United States and elsewhere may be 
subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, transparency, health information 
privacy and security and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, 
contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

As  a  clinical-stage  company  that  could  potentially  become  a  commercial  pharmaceutical  company,  even  though  we 
will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, certain federal 
and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights will be applicable to our business. 
Our potential future arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse 
and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal False 
Claims Act, which may constrain the business or financial arrangements and relationships through which we may sell, market 
and  distribute  any  drugs  for  which  we  obtain  marketing  approval.  In  addition,  we  may  be  subject  to  transparency  laws  and 
patient  privacy  regulation  by  U.S.  federal  and  state  governments  and  by  governments  in  foreign  jurisdictions  in  which  we 
conduct our business. The laws that may affect our ability to operate include:

•

•

•

the  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  from  knowingly  and  willfully 
soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, 
or  in  return  for,  either  the  referral  of  an  individual  for,  or  the  purchase,  order,  lease,  furnishing,  prescribing  or 
recommendation of, any good or service, for which payment may be made under federal and state healthcare programs, 
such as Medicare and Medicaid. The term “remuneration” has been broadly interpreted to include anything of value. 
The ACA, among other things, amended the intent requirement of the federal Anti‑Kickback Statute such that a person 
or  entity  no  longer  needs  to  have  actual  knowledge  of  the  statute  or  specific  intent  to  violate,  in  order  to  commit  a 
violation;

federal civil and criminal false claims laws, including the federal False Claims Act which can be enforced by private 
individuals  on  behalf  of  the  government  through  civil  whistleblower  or  qui  tam  actions,    and  civil  monetary  penalty 
laws  prohibit  individuals  or  entities  for  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government, 
including  the  Medicare  and  Medicaid  programs,  claims  for  payment  that  are  false  or  fraudulent  or  making  a  false 
statement  to  avoid,  decrease  or  conceal  an  obligation  to  pay  money  to  the  federal  government.  Entities  can  be  held 
liable  under  these  laws  if  they  are  deemed  to  “cause”  the  submission  of  false  or  fraudulent  claims  by,  for  example, 
providing  inaccurate  billing  or  coding  information  to  customers,  promoting  a  product  off‑label,  or  for  providing 
medically unnecessary services or items. In addition, a claim including items or services resulting from a violation of 
the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act;

the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which imposes criminal and civil 
liability  for  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit 
program,  including  third-party  payors,  knowingly  and  willfully  embezzling  or  stealing  from  a  healthcare  benefit 
program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, 

25

•

•

•

concealing  or  covering  up  a  material  fact  or  making  any  materially  false,  fictitious  or  fraudulent  statements  in 
connection with the delivery of or payment for healthcare benefits, items or services;

HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  of  2009 
(“HITECH”), and their respective implementing regulations, which impose obligations on certain healthcare providers, 
health plans, and healthcare clearinghouses, known as covered entities, as well as individuals and entities that create, 
receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity, known as 
business  associates,  as  well  as  their  covered  subcontractors,  with  respect  to  safeguarding  the  privacy,  security  and 
transmission of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, 
amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys 
general  new  authority  to  file  civil  actions  for  damages  or  injunctions  in  U.S.  federal  courts  to  enforce  the  federal 
HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions;

the federal Open Payments program, which requires manufacturers of drugs, devices, biologics and medical supplies for 
which  payment  is  available  under  Medicare,  Medicaid  or  the  Children’s  Health  Insurance  Program,  with  specific 
exceptions, to report annually to CMS information related to “payments or other transfers of value” made to physicians, 
which is defined to include doctors, dentists, optometrists, podiatrists and chiropractors, other health care professionals 
(such as physician assistances and nurse practitioners), and teaching hospitals and ownership and investment interests 
held by such healthcare professionals and their immediate family members; and

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to 
sales  or  marketing  arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-governmental 
third-party payors, including private insurers; state and foreign laws that require pharmaceutical companies to comply 
with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated 
by the federal government or otherwise restrict payments that may be made to healthcare providers; state and foreign 
laws that require drug manufacturers to report information related to payments and other transfers of value to physicians 
and  other  healthcare  providers,    marketing  expenditures,  or  drug  pricing;  state  and  local  laws  that  require  the 
registration  of  pharmaceutical  sales  representatives;  and  state  and  foreign  laws  governing  the  privacy  and  security  of 
health information in certain circumstances, many of which differ from each other in significant ways and often are not 
preempted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory safe harbors, 
it is possible that some of our business activities could be subject to challenge under one or more of such laws. To the extent 
that any of our product candidates is ultimately sold in countries other than the United States, we may be subject to similar laws 
and regulations in those countries. If we or our operations are found to be in violation of any of the laws described above or any 
other  governmental  regulations  that  apply  to  us,  we  may  be  subject  to  penalties,  including  significant  civil,  criminal  and 
administrative  penalties,  damages,  fines,  imprisonment,  disgorgement,  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, 
exclusion from participation in government healthcare programs, and the curtailment or restructuring of our operations, any of 
which could have a material adverse effect on our business. If any of the physicians or other healthcare providers or entities 
with whom we expect to do business, including any of our collaborators, is found not to be in compliance with applicable laws, 
they  may  be  subject  to  significant  criminal,  civil  or  administrative  sanctions,  including  exclusion  from  participation  in 
government healthcare programs, which could also materially affect our business.

We are subject to stringent and changing obligations related to data privacy and security.  Our actual or perceived 
failure  to  comply  with  such  obligations  could  lead  to  regulatory  investigations  or  actions;  litigation;  fines  and  penalties; 
disruptions of our business operations, reputational harm, and other adverse business impacts.

In  the  ordinary  course  of  business,  we  process  personal  data  and  other  sensitive  data,  including  proprietary  and 
confidential business data, trade secrets, intellectual property, data we collect about trial participants in connection with clinical 
trials,  and  sensitive  third-party  data.  Our  data  processing  activities  also  subject  us  to  numerous  data  privacy  and  security 
obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and security policies, 
contracts, and other obligations that govern the processing of personal data by us and on our behalf. 

In  the  United  States,  federal,  state,  and  local  governments  have  enacted  numerous  data  privacy  and  security  laws, 
including data breach notification laws, personal data privacy laws, and consumer protection laws. The California Consumer 
Privacy  Act  of  2018  (“CCPA”)  imposes  obligations  on  businesses  to  which  it  applies.  These  obligations  include,  without 
limitation, providing specific disclosures in privacy notices, affording California residents certain rights related to their personal 
data, and requiring businesses subject to the CCPA to implement certain measures to effectuate California residents’ personal 

26

data rights. The CCPA allows for statutory fines for noncompliance (up to $7,500 per violation). In addition, it is anticipated 
that the California Privacy Rights Act of 2020 (“CPRA”), effective January 1, 2023, will expand the CCPA. For example, the 
CPRA establishes a new California Privacy Protection Agency to implement and enforce the CCPA (as amended), which could 
increase  the  risk  of  an  enforcement  action.  Other  states  have  enacted  data  privacy  laws.    For  example,  Virginia  passed  its 
Consumer  Data  Protection  Act,  and  Colorado  passed  the  Colorado  Privacy  Act,  both  of  which  differ  from  the  CPRA  and 
become effective in 2023.

Outside the United States, an increasing number of laws, regulations, and industry standards apply to data privacy and 
security.  For example, the European Union’s General Data Protection Regulation (“EU GDPR”) and the UK’s GDPR (“UK 
GDPR”) impose strict requirements for processing the personal data of individuals located, respectively, within the EEA and 
the  UK.  For  example,  under  the  EU  GDPR,  government  regulators  may  impose  temporary  or  definitive  bans  on  data 
processing, as well as fines up to 20 million euros or 4% of the annual global revenue, whichever is greater. Further, individuals 
may initiate litigation related to our processing of their personal data.

Certain jurisdictions have enacted data localization laws and cross-border personal data transfers laws. For example, 
absent appropriate safeguards or other circumstances, the EU GDPR generally restricts the transfer of personal data to countries 
outside of the EEA, such as the United States, which the European Commission does not consider to provide an adequate level 
of personal data protection. The European Commission released a set of “Standard Contractual Clauses” that are designed to be 
a valid mechanism by which entities can transfer personal data out of the EEA to jurisdictions that the European Commission 
has not found to provide an adequate level of protection. Currently, these Standard Contractual clauses are a valid mechanism to 
transfer personal data outside of the EEA. The Standard Contractual Clauses, however, require parties that rely upon that legal 
mechanism  to  comply  with  additional  obligations  such  as  conducting  transfer  impact  assessments  to  determine  whether 
additional  security  measures  are  necessary  to  protect  the  at-issue  personal  data.  Moreover,  due  to  potential  legal  challenges, 
there exists some uncertainty regarding whether the Standard Contractual Clauses will remain a valid mechanism for personal 
data transfers out of the EEA. In addition, laws in Switzerland and the UK similarly restrict personal data transfers outside of 
those jurisdictions to countries such as the United States that do not provide an adequate level of personal data protection. In 
addition  to  European  restrictions  on  cross-border  personal  data  transfers,  other  jurisdictions  have  enacted  or  are  considering 
similar cross-border personal data transfer laws and local personal data residency laws, any of which could increase the cost and 
complexity of doing business. If we cannot implement a valid compliance mechanism for cross-border personal data transfers, 
we  may  face  increased  exposure  to  regulatory  actions,  substantial  fines,  and  injunctions  against  processing  or  transferring 
personal data from Europe or elsewhere.  Inability to import personal data to the United States may significantly and negatively 
impact  our  business  operations,  including  by  limiting  our  ability  to  conduct  clinical  trial  activities  in  Europe  and  elsewhere; 
limiting our ability to collaborate with parties subject to European and other data protection laws or requiring us to increase our 
personal data processing capabilities in Europe and/or elsewhere at significant expense.

Our obligations related to data privacy and security are quickly changing in an increasingly stringent fashion. These 
obligations  may  be  subject  to  differing  applications  and  interpretations,  which  may  be  inconsistent  among  jurisdictions  or  in 
conflict.  Preparing  for  and  complying  with  these  obligations  requires  us  to  devote  significant  resources  (including,  without 
limitation,  financial  and  time-related  resources).  These  obligations  may  necessitate  changes  to  our  information  technologies, 
systems, and practices and those of any third parties that process personal data on our behalf.  In addition, these obligations may 
even require us to change to our business model. Although we endeavor to comply with all applicable data privacy and security 
obligations, we may at times fail (or be perceived to have failed) to do so.  Moreover, despite our efforts, our personnel or third-
parties upon whom we rely may fail to comply such obligations that impacts our compliance posture.  

If we fail, or are perceived to have failed, to address or comply with data privacy and security obligations, we could 
face significant consequences.  These consequences may include, but are not limited to, government enforcement actions (e.g., 
investigations, fines, penalties, audits, inspections and similar); litigation (including class-related claims); additional reporting 
requirements and/or oversight; bans on processing personal data; and orders to destroy or not use personal data. Any of these 
events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss 
of customers; interruptions or stoppages in our business operations (including clinical trials); inability to process personal data 
or operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources 
to defend any claim or inquiry; adverse publicity; or revision or restructuring our operations.  

Changes  in  funding  for  the  FDA,  the  SEC  and  other  government  agencies,  or  shutdowns,  travel  restrictions  or 
furloughs,  could  hinder  their  ability  to  hire  and  retain  key  leadership  and  other  personnel,  prevent  new  products  and 
services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing 
normal functions on which the operation of our business may rely, which could negatively impact our business.

27

The  ability  of  the  FDA  to  review  and  approve  new  products  can  be  affected  by  a  variety  of  factors,  including 
government budget and funding levels, travel restrictions, ability to hire and retain key personnel and accept payment of user 
fees,  and  statutory,  regulatory,  and  policy  changes.  Average  review  times  at  the  agency  have  fluctuated  in  recent  years  as  a 
result. In addition, government funding of the SEC and other government agencies on which our operations may rely, including 
those  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  may  also  slow  the  time  necessary  for  new  drugs  to  be  reviewed  and/or 
approved  by  necessary  government  agencies,  which  would  adversely  affect  our  business.  For  example,  over  the  last  several 
years, including most recently beginning on December 22, 2018, the U.S. government has shut down several times and certain 
regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees 
and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to 
timely  review  and  process  our  regulatory  submissions,  which  could  have  a  material  adverse  effect  on  our  business.  Further, 
future  government  shutdowns  could  impact  our  ability  to  access  the  public  markets  and  obtain  necessary  capital  in  order  to 
properly capitalize and continue our operations.

We may become subject to the risk of product liability claims.

We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an 
even greater risk if we commercialize any products. Human therapeutic products involve the risk of product liability claims and 
associated  adverse  publicity.  Currently,  the  principal  risks  we  face  relate  to  patients  in  our  clinical  trials,  who  may  suffer 
unintended  consequences.  Claims  might  be  made  by  patients,  healthcare  providers,  pharmaceutical  companies  or  others.  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 
warranties.  Claims  could  also  be  asserted  under  state  consumer  protection  laws.    If  we  cannot  successfully  defend  ourselves 
against  product  liability  claims,  we  may  incur  substantial  liabilities  or  be  required  to  limit  commercialization  of  our  product 
candidates, if approved. 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 our product candidates;

injury to our reputation;

withdrawal of clinical trial participants;

initiation of investigations by regulators;

costs to defend the related litigation;

a diversion of management’s time and our resources;

substantial monetary awards to trial participants or patients;

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

loss of revenue from product sales; and

the inability to commercialize any of our product candidates, if approved.

We may not have or be able to obtain or maintain sufficient and affordable insurance coverage, and without sufficient 
coverage any claim brought against us could have a materially adverse effect on our business, financial condition or results of 
operations.  We  run  clinical  trials  through  investigators  that  could  be  negligent  through  no  fault  of  our  own  and  which  could 
affect  patients,  cause  potential  liability  claims  against  us  and  result  in  delayed  or  stopped  clinical  trials.  We  are  required  in 
many  cases  by  contractual  obligations  to  indemnify  collaborators,  partners,  third-party  contractors,  clinical  investigators  and 
institutions.  These  indemnifications  could  result  in  a  material  impact  due  to  product  liability  claims  against  us  and/or  these 
groups.  We  currently  carry  $10  million  in  product  liability  insurance,  which  we  believe  is  appropriate  for  our  clinical  trials. 
Although we maintain such insurance, 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 

28

coverage. Our insurance policies also have various exclusions, 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 capital to pay such 
amounts.

Our business involves the controlled use of hazardous materials and as such we are subject to environmental and 
occupational  safety  laws.  Continued  compliance  with  these  laws  may  incur  substantial  costs  and  failure  to  maintain 
compliance could result in liability for damages that may exceed our resources.

Our  preclinical  research,  manufacturing  and  development  processes  involve  the  controlled  use  of  hazardous  and 
radioactive materials. We are subject to federal, local and foreign laws and regulations governing the use, manufacture, storage, 
handling and disposal of such materials and certain waste products. Our operations involve the use of hazardous and flammable 
materials,  including  chemicals  and  biological  materials.  Our  operations  also  produce  hazardous  waste  products.  The  risk  of 
accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, we 
could be held liable for any damages that result, and any such liability could exceed our resources. We may not be adequately 
insured  against  this  type  of  liability.  We  may  be  required  to  incur  significant  costs  to  comply  with  environmental  laws  and 
regulations  in  the  future,  and  our  operations,  business  or  assets  may  be  materially  adversely  affected  by  current  or  future 
environmental laws or regulations.

We may have to dedicate resources to the settlement of litigation.

Securities legislation in the United States, Canada and other countries makes it relatively easy for shareholders to sue. 
This could lead to frivolous lawsuits which could take substantial time, money, resources and attention or force us to settle such 
claims rather than seek adequate judicial remedy or dismissal of such claims.

If we are required to defend patent infringement actions brought by third parties, or if we sue to protect our own patent 
rights or otherwise to protect our proprietary information and to prevent its disclosure, or if we are involved in other litigation, 
whether  as  a  plaintiff  or  defendant,  we  may  be  required  to  pay  substantial  litigation  costs  and  managerial  attention  may  be 
diverted from business operations even if the outcome is in our favor. If we are required to defend our patents or trademarks 
against  infringement  by  third  parties,  we  may  be  required  to  pay  substantial  litigation  costs  and  managerial  attention  and 
financial resources may be diverted from our research and development operations even if the outcome is in our favor.

If  our  information  technology  systems  or  data  is  or  were  compromised,  we  could  experience  adverse  impacts 
resulting  from  such  compromise,  including,  but  not  limited  to  interruptions  to  our  operations  such  as  our  clinical  trials, 
claims that we breached our data protection obligations, and harm to our reputation.

In the ordinary course of our business, we may collect, store, use, transmit, disclose or otherwise process proprietary, 
confidential, and sensitive data, including personal data (such as health-related data), intellectual property, and trade secrets. We 
are dependent upon our own or third-party information technology systems, infrastructure and data, to operate our business.

Cyberattacks,  malicious  internet-based  activity,  and  online  and  offline  fraud  are  prevalent  and  continue  to  increase.  
These  threats  are  becoming  increasingly  difficult  to  detect.  These  threats  come  from  a  variety  of  sources.  In  addition  to 
traditional computer “hackers,” threat actors, personnel misconduct or error (such as theft or misuse), sophisticated nation-state 
and nation-state supported actors now engage in attacks. We may be subject to a variety of evolving threats, including but not 
limited to social engineering attacks (including through phishing attacks), malicious code (such as viruses and worms), malware 
(including  as  a  result  of  advanced  persistent  threat  intrusions),  denial-of-service  attacks  (such  as  credential  stuffing), 
ransomware  attacks,  supply-chain  attacks,  software  bugs,  server  malfunction,  software  or  hardware  failures,  loss  of  data  or 
other  information  technology  assets,  adware,  telecommunications  failures,  and  other  similar  threats.    Ransomware  attacks, 
including those perpetrated by organized criminal threat actors, nation-states, and nation-state supported actors, are becoming 
increasingly  prevalent  and  severe  and  can  lead  to  significant  interruptions  in  our  operations,  loss  of  data  and  income, 
reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we 
may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting payments.  
Similarly,  supply-chain  attacks  have  increased  in  frequency  and  severity,  and  we  cannot  guarantee  that  third  parties  and 
infrastructure in our supply chain have not been compromised or that they do not contain exploitable defects or bugs that could 
result in a breach of or disruption to our information technology systems (including our products/operational activities) or the 
third-party  information  technology  systems  that  support  us  and  our  operational  activities.  The  COVID-19  pandemic  and  our 
remote workforce poses increased risks to our information technology systems and data, as more of our employees work from 
home, utilizing network connections outside our premises.

29

Any of the previously identified or similar threats could cause a security incident. A security incident could result in 
unauthorized, unlawful or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of or access 
to data. A security incident could disrupt our (and third parties upon whom we rely) ability to provide our products. Any system 
failure,  accident  or  security  breach  that  causes  interruptions  in  our  own,  in  collaborators’  or  in  third-party  service  vendors’ 
operations  could  result  in  a  material  disruption  of  our  drug  discovery  and  development  programs  or  theft  of  our  intellectual 
property.  We  may  expend  significant  resources  or  modify  our  business  activities  (including  our  clinical  trial  activities)  in  an 
effort to protect against security incidents.

Certain  data  privacy  and  security  obligations  may  require  us  to  implement  and  maintain  specific  security  measures, 

industry-standard or reasonable security measures to protect our information technology systems and data.

We  devote  considerable  internal  and  external  resources  to  implementing  security  measures  to  protect  our  systems, 
customers, and users, but these security measures cannot provide absolute security. We may be unable to detect vulnerabilities 
in  our  information  technology  systems  (including  our  products)  because  such  threats  and  techniques  change  frequently,  are 
often sophisticated in nature, and may not be detected until after a security incident has occurred. Despite our efforts to identify 
and remediate vulnerabilities, if any, in our information technology systems (including our products), our efforts may not be 
successful. Further, we may experience delays in developing and deploying remedial measures designed to address any such 
identified vulnerabilities.

Potential  breaches  of  our  security  measures  and  the  accidental  loss,  inadvertent  disclosure,  or  unapproved 
dissemination of proprietary information, intellectual property, or sensitive or confidential data about us, our employees, or our 
customers or users (including the potential loss or disclosure of such information or data as a result of employee error or other 
employee actions or inactions, hacking, fraud, social engineering, or other forms of deception) could expose us, our customers, 
or the individuals affected to a risk of loss or misuse of this information, result in litigation and potential liability for us, damage 
our brand and reputation, or otherwise materially adversely affect our business, results of operations, and financial condition. 
Applicable  data  privacy  and  security  obligations  may  require  us  to  notify  relevant  stakeholders  of  security  incidents.  Such 
disclosures are costly, and the disclosures or the failure to comply with such requirements, could lead to adverse impacts.

In  addition,  the  cost  and  operational  consequences  of  implementing  further  data  protection  measures  could  be 
significant and theft of our intellectual property or proprietary business information could require substantial expenditures to 
remedy. Further, we cannot be certain that (a) our liability insurance will be sufficient in type or amount to cover us against 
claims related to security breaches, cyberattacks and other related breaches; (b) such coverage will cover any indemnification 
claims against us relating to any incident, will continue to be available to us on economically reasonable terms, or at all; or (c) 
any insurer will not deny coverage as to any future claim.  The successful assertion of one or more large claims against us that 
exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the 
imposition of large deductible or co-insurance requirements, could adversely affect our reputation, business, financial condition 
and results of operations.

In addition, we rely upon third-party contractors and service providers for the hosting, support and/or maintenance of 
some aspects of our computer hardware, computer software and telecommunications systems.  Failure of those contractors and 
service providers to provide systems and services of a suitable quality and within acceptable timeframes may cause the delay or 
failure  of  our  development  programs,  or  loss  of  confidential  or  proprietary  information.  To  the  extent  that  any  disruption  or 
security breach results in a loss or damage to our data or applications, or inappropriate disclosure of confidential or proprietary 
information, we may incur liability, our drug discovery and development programs may be adversely affected and the further 
development  of  our  product  candidates  may  be  delayed.  Furthermore,  such  disruptions  or  security  breaches  could  harm  our 
reputation, compel us to comply with federal and/or  state breach notification laws and foreign law equivalents, subject us to 
mandatory corrective action, require us to verify the correctness of database contents and otherwise subject us to litigation or 
other liability under laws and regulations that protect personal data, any of which could disrupt our business and/or result in 
increased costs. 

Risks Related to Our Financial Position and Capital Requirements

We  will  require  additional  financing  and  may  be  unable  to  raise  sufficient  capital,  which  could  lead  us  to  delay, 

reduce or abandon development programs or commercialization.

Our operations have consumed substantial amounts of cash since inception. Our research and development expenses 
were $508.6 million, $299.3 million, and $182.9 million for the years ended December 31, 2021, 2020 and 2019, respectively. 
Our net loss for the years ended December 31, 2021, 2020, and 2019 were $581.8 million, $357.9 million, and $213.3 million 
respectively. As of December 31, 2021, we had an accumulated deficit of $1.7 billion. We may require substantial additional 

30

capital to pursue additional clinical development for our lead clinical programs, including conducting late-stage clinical trials, 
manufacturing clinical supplies and developing other assets in our pipeline, and, if we are successful, to commercialize any of 
our  current  product  candidates.  If  the  UFDA  or  any  foreign  regulatory  agency,  such  as  the  EMA  requires  that  we  perform 
studies or trials in addition to those that we currently anticipate with respect to the development of our product candidates, or 
repeat studies or trials, or if our clinical trials are otherwise delayed or disrupted due to the COVID-19 pandemic or otherwise, 
our  expenses  would  further  increase  beyond  what  we  currently  expect.  We  may  not  be  able  to  adequately  finance  our 
development  programs,  which  could  limit  our  ability  to  move  our  programs  forward  in  a  timely  and  satisfactory  manner  or 
require  us  to  abandon  the  programs,  any  of  which  would  harm  our  business,  financial  condition  and  results  of  operations. 
Because successful development of our product candidates is uncertain, we are unable to accurately estimate the actual funds 
we will require to complete research and development and commercialize our product candidates.

If, at any point, we are unable to obtain funding from equity offerings or debt financings on a timely basis, we may be 
required to (1) seek additional collaborators for one or more of our product candidates at an earlier stage than otherwise would 
be desirable or on terms that are less favorable than might otherwise be available; (2) relinquish or license on unfavorable terms 
our  rights  to  technologies  or  product  candidates  that  we  otherwise  would  seek  to  develop  or  commercialize  ourselves;  or 
(3) significantly curtail one or more of our research or development programs or cease operations altogether.

We may not generate revenue from sales of products. If any of our product candidates fail in clinical trials or do not 
gain  regulatory  approval,  or  if  any  of  our  product  candidates,  if  approved,  fail  to  achieve  market  acceptance,  we  may  never 
become profitable. If one or more of our product candidates is approved for commercial sale and we retain commercial rights, 
we anticipate incurring significant costs associated with commercializing any such approved product candidate. Therefore, even 
if we are able to generate revenue from the sale of any approved product, we may never become profitable. Even if we achieve 
profitability  in  the  future,  we  may  not  be  able  to  sustain  profitability  in  subsequent  periods.  Our  ability  to  generate  future 
revenue from product sales depends heavily on our success in:

•

•

•

•

•

•

completing development and clinical trial programs for our product candidates;

maintaining existing collaboration and licensing agreements and entering into additional ones;

seeking and obtaining marketing approvals for any product candidates that successfully complete clinical trials;

establishing and maintaining supply and manufacturing relationships with third parties;

successfully commercializing any product candidates for which marketing approval is obtained; and

successfully establishing a sales force and marketing and distribution infrastructure.

We are a clinical-stage company with no approved products and no product revenue. Consequently, we expect that 

our financial and operating results will vary significantly from period to period.

We are a clinical-stage company that has incurred losses since its inception and expect to continue to incur substantial 
losses  in  the  foreseeable  future.  Biopharmaceutical  product  development  is  a  highly  speculative  undertaking  and  involves  a 
substantial degree of uncertainty.

Our actual financial condition and operating results have varied significantly in the past and are expected to continue 
to  fluctuate  significantly  from  quarter-to-quarter  or  year-to-year  due  to  a  variety  of  factors,  many  of  which  are  beyond  our 
control. Factors relating to our business that may contribute to these fluctuations include:

•

•

•

•

•

the success of our clinical trials through all phases of clinical development;

delays in the commencement, enrollment and timing of clinical trials;

delays due to force majeure;

our  ability  to  secure  and  maintain  collaborations,  licensing  or  other  arrangements  for  the  future  development  and/or 
commercialization of our product candidates, as well as the terms of those arrangements;

our ability to obtain, as well as the timeliness of obtaining, additional funding to develop our product candidates;

31

•

•

•

•

•

•

•

•

•

•

•

•

•

the  results  of  clinical  trials  or  marketing  applications  for  product  candidates  that  may  compete  with  our  product 
candidates;

competition from existing products or new products that may receive marketing approval;

potential side effects of our product candidates that could delay or prevent approval or cause an approved drug to be 
taken off the market;

any delays in regulatory review and approval of our clinical development plans or product candidates;

our ability to identify and develop additional product candidates;

the ability of patients or healthcare providers to obtain coverage or sufficient reimbursement for our products;

our ability, and the ability of third parties such as CROs to adhere to clinical study and other regulatory requirements;

the ability of third-party manufacturers to manufacture our product candidates and key ingredients needed to conduct 
clinical trials and, if approved, successfully commercialize our products;

the costs to us, and our ability as well as the ability of any third-party collaborators, to obtain, maintain and protect our 
intellectual property rights;

costs related to and outcomes of potential intellectual property litigation;

our ability to adequately support future growth;

our ability to attract and retain key personnel to manage our business effectively; and

our ability to build our finance infrastructure and, to the extent required, improve our accounting systems and controls.

Accordingly,  the  likelihood  of  our  success  must  be  evaluated  in  light  of  many  potential  challenges  and  variables 
associated  with  a  clinical-stage  company,  many  of  which  are  outside  of  our  control,  and  past  operating  or  financial  results 
should  not  be  relied  on  as  an  indication  of  future  results.  Fluctuations  in  our  operating  and  financial  results  could  cause  our 
share price to decline. It is possible that in some future periods, our operating results will be above or below the expectations of 
securities analysts or investors, which could also cause our share price to decline.

Raising  additional  funds  through  debt  or  equity  financing  will  be  dilutive  and  raising  funds  through  licensing 

agreements may be dilutive, restrict operations or relinquish proprietary rights.

To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of 
those securities could result in substantial dilution for our current shareholders and the terms may include liquidation or other 
preferences that adversely affect the rights of our current shareholders. Existing shareholders may not agree with our financing 
plans  or  the  terms  of  such  financings.  In  addition,  the  COVID-19  pandemic  continues  to  rapidly  evolve  and  may  result  in  a 
significant disruption of global financial markets. Our ability to raise additional capital may be adversely impacted by potential 
worsening  global  economic  conditions  and  the  recent  disruptions  to,  and  volatility  in,  the  credit  and  financial  markets  in  the 
U.S.  and  worldwide  resulting  from  the  pandemic.  If  the  disruption  persists  and  deepens,  we  could  experience  an  inability  to 
access additional capital, which could in the future negatively affect our capacity to fund research and development programs, 
including discovery research, preclinical and clinical development activities. Moreover, the incurrence of debt financing could 
result  in  a  substantial  portion  of  our  operating  cash  flow  being  dedicated  to  the  payment  of  principal  and  interest  on  such 
indebtedness  and  could  impose  restrictions  on  our  operations.  In  addition,  if  we  raise  additional  funds  through  future 
collaboration  and  licensing  arrangements,  it  may  be  necessary  to  relinquish  potentially  valuable  rights  to  our  products  or 
proprietary technologies, or to grant licenses on terms that are not favorable to us. Additional funding may not be available to 
us on acceptable terms, or at all.

Our ability to use our U.S. net operating loss carryforwards and certain other tax attributes may be limited.

Our U.S. federal net operating loss (“NOL”), carryforwards generated in tax years beginning before January 1, 2018, 
are  only  permitted  to  be  carried  forward  for  20  years  under  applicable  U.S.  tax  law.  Under  current  law,  our  federal  NOLs 
generated in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such 

32

federal NOLs in tax years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what 
extent various states will conform to federal tax laws. In addition, under Sections 382 and 383 of the Code, and corresponding 
provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% 
change,  by  value,  in  its  equity  ownership  over  a  three-year  period,  the  corporation’s  ability  to  use  its  pre-change  NOL 
carryforwards and other pre-change U.S. tax attributes (such as research tax credits) to offset its post-change income or taxes 
may be limited.

As a result, our NOL carryforwards generated in tax years beginning before January 1, 2018 may expire prior to being 
used, and the deductibility of our NOL carryforwards generated in tax years beginning after December 31, 2017 will be subject 
to a percentage limitation, in taxable years beginning after December 31, 2020.  In addition, we believe that we have in the past 
undergone, and in the future it is possible we may undergo, additional ownership changes that could limit our ability to use all 
of our pre-change NOLs and other pre-change tax attributes (such as research tax credits) to offset our post-change income or 
taxes. Similar provisions of state tax law may also apply to limit our use of accumulated state tax attributes. In addition, at the 
state level, there may be periods during which the use of NOLs or other tax attributes is suspended or otherwise limited, which 
could accelerate or permanently increase state taxes owed. As a result, we may be unable to use all or a material portion of our 
NOLs and other tax attributes, which could adversely affect our future cash flows.

Risks Related to Our Intellectual Property

We  may  not  obtain  adequate  protection  for  our  products  and/or  product  candidates  through  patents  and  other 

intellectual property rights and as such, our competitive advantage in the marketplace may be compromised.

Our success depends to a significant degree upon on our ability to develop, secure and maintain intellectual property 
rights  to  our  proprietary  products,  to  operate  without  infringing  on  the  proprietary  rights  of  others  or  having  third  parties 
circumvent the rights that we own or license. We have filed and are actively pursuing patent applications in the United States, 
Japan, Europe and other major markets via the Patent Cooperation Treaty or directly in countries of interest. However, we may 
not  receive  issued  patents  on  any  of  our  pending  patent  applications  in  these  countries  and  we  may  not  be  able  to  obtain, 
maintain or enforce our patents and other intellectual property rights which could impact our ability to compete effectively. We 
cannot  be  certain  that  the  U.S.  Patent  and  Trademark  Office,  courts  in  the  United  States  or  the  patent  offices  and  courts  in 
foreign  countries  will  consider  the  claims  in  our  patents  and  applications  covering  any  of  our  products  in  development  as 
patentable. In addition, the scope of any of our issued patents may not be sufficiently broad to provide us with a competitive 
advantage.  Furthermore,  other  parties  may  successfully  challenge,  invalidate  or  circumvent  our  issued  patents  or  patents 
licensed to us so that our patent rights do not create an effective competitive barrier.  Our method-of-use patents protect the use 
of  a  product  only  for  the  specified  method.  This  type  of  patent  does  not  prevent  a  competitor  from  making  and  marketing  a 
product  that  is  identical  to  our  product  for  an  indication  that  is  outside  the  scope  of  the  patented  method.  Moreover,  even  if 
competitors  do  not  actively  promote  their  product  for  our  targeted  indications,  physicians  may  prescribe  these  products  off-
label. Although off-label prescriptions may infringe or contribute to the infringement of method-of-use patents, the practice is 
common and such infringement is difficult to prevent, including through legal action. Further, if the patent applications we own 
or  license  with  respect  to  our  programs,  product  candidates  and/or  companion  diagnostic  fail  to  issue,  if  their  breadth  or 
strength  of  protection  is  threatened,  or  if  they  fail  to  provide  meaningful  exclusivity  for  our  product  candidates,  it  could 
dissuade companies from collaborating with us to develop product candidates, and threaten our ability to commercialize future 
products.

We may file applications for trademark registrations in connection with our product candidates in various jurisdictions, 
including the United States. No assurance can be given that any of our trademark applications will be registered in the United 
States  or  elsewhere,  or  that  the  use  of  any  registered  or  unregistered  trademarks  will  confer  a  competitive  advantage  in  the 
marketplace. Furthermore, even if we are successful in our trademark registrations, the FDA and regulatory authorities in other 
countries  have  their  own  process  for  drug  nomenclature  and  their  own  views  concerning  appropriate  proprietary  names.  The 
loss, abandonment, or cancellation of any of our trademarks or trademark applications could negatively affect the success of the 
product candidates to which they relate.

Moreover, some of our know-how and technology which is not patented or not patentable may constitute trade secrets. 
Therefore, we require our consultants, advisors and collaborators to enter into confidentiality agreements and our employees to 
enter into invention and non-disclosure agreements. However, no assurance can be given that such agreements will provide for 
a meaningful protection of our trade secrets, know-how or other proprietary information in the event of any unauthorized use or 
disclosure of information. Furthermore, we cannot provide assurance that any of our employees, consultants, contract personnel 
or collaborators, either accidentally or through willful misconduct, will not cause serious negative impact to our programs and/
or our strategy. All of our employees have signed confidentiality agreements, but there can be no assurance that they will not 
inadvertently or through their misconduct give trade secrets away.

33

Third-party patents or intellectual property infringement claims may result in a reduction in the scope of our patent 
protection  and  competitive  exclusivity  with  respect  to  our  product  candidates.  Patent  litigation,  including  defense  against 
third-party intellectual property claims, may result in us incurring substantial costs.

Our patents may be challenged by third parties from time to time, and we will have to defend our intellectual property 
rights. If we are involved in an intellectual property dispute, we may need to litigate to defend our rights or assert them against 
others. Disputes can involve arbitration, litigation or proceedings declared by the United States Patent and Trademark Office or 
the International Trade Commission or foreign patent authorities. These disputes can result in the successful invalidation of our 
patents  or  reduction  in  scope  so  that  our  patent  rights  do  not  create  an  effective  competitive  barrier.  Even  if  resolved  in  our 
favor, litigation or other legal proceedings relating to intellectual property claims 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. 

It  is  possible  that  third  parties  will  circumvent  our  patents  by  means  of  alternate  designs  or  processes  or  file 
applications or be granted patents that would block or hamper our efforts. Further, a third party may claim that our products or 
technology infringe its patents or other intellectual property rights, as such we may have to discontinue or alter our products and 
processes, pay license fees or cease certain activities. We may not be able to obtain a license to needed intellectual property on 
favorable terms, if at all. There are many patents issued or applied for in the biotechnology industry, and we may not be aware 
of patents or patent applications held by others that relate to our business. This is especially true since patent applications in the 
U.S. and elsewhere are filed confidentially for the first 18 months. Moreover, the validity and breadth of biotechnology patents 
involve complex legal and factual questions for which important legal issues remain.

Maintaining our patents and applications requires timely payment of fees and other associated costs in the countries of 
filing, and we could inadvertently abandon a patent or patent application (or trademark or trademark application) due to non-
payment  of  fees,  or  as  a  result  of  a  failure  to  comply  with  filing  deadlines  or  other  requirements  of  the  prosecution  process, 
resulting in the loss of protection of certain intellectual property rights in a certain country. Alternatively, we, our collaborators 
or our patent counsel may take action resulting in a patent or patent application becoming abandoned which may not be able to 
be reinstated, or if reinstated, may suffer negative patent term adjustments. Any of these outcomes could hurt our ability to gain 
full  patent  protection  for  our  products.  Registered  trademarks  and/or  applications  for  trademark  registrations  in  the  United 
States that belong to us are subject to similar risks as described above for patents and patent applications.

Third parties may seek to obtain approval of a generic version of approved products.  Defense against entry of a 
generic  product  may  result  in  us  incurring  substantial  costs  and  ultimate  failure  to  prevail  against  approval  of  a  generic 
product could result in a substantial loss of market share and profits.

Even  if  we  are  successful  in  obtaining  regulatory  approval  to  sell  any  of  our  product  candidates  in  one  or  more 
countries, we cannot be certain that our patents and other intellectual property rights will ultimately prevent approval during the 
patent term of generic products developed and commercialized by third parties.  A generic manufacturer may seek approval of a 
generic  version  of  any  of  our  products  in  the  United  States  by  filing  an  Abbreviated  New  Drug  Application  with  the  FDA, 
asserting that our patents are invalid and/or unenforceable to maintain market exclusivity for any of our products, if approved. 
We cannot predict if, or when, one or more generic manufacturers may attempt to seek regulatory approval for a generic version 
of any of our products, if approved. There is no assurance that we will ultimately be successful in a court of law to prevent entry 
of a generic version of any of our products during the applicable patent term and we may incur substantial costs defending our 
patents  and  intellectual  property  rights.  An  inability  to  stop  a  generic  manufacturer  from  selling  a  generic  version  of  our 
products could result in a substantial loss of market share and profits or even preclude the ability to continue to commercialize 
any of our products, if approved.

Risks Related to Our Shares of Common Stock

Our principal shareholders control the majority of our shares, and their actions may significantly influence matters 

submitted to our shareholders for approval and our share price.

Based on the information available to us as of December 31, 2021, our shareholders and their affiliates who owned 
more  than  5%  of  our  outstanding  common  stock  collectively  owned  39%  of  our  outstanding  common  stock.  Boxer  Capital, 
LLC (“Boxer Capital”) and its affiliates collectively own 10% of our outstanding common stock. In addition, in conjunction 
with certain financing transactions, we granted Boxer Capital the right to nominate a member of our Board of Directors and the 
right  to  appoint  an  observer  on  our  Board  of  Directors.  In  addition,  we  granted  Baker  Brothers  Advisors,  LLC  (“Baker 

34

Brothers”) the right to appoint an observer on our Board of Directors. Collectively Baker Brothers and Boxer Capital may have 
significant influence over matters submitted to our shareholders for approval, including the election and removal of directors 
and the approval of any merger, consolidation, or sale of all or substantially all of our assets. Furthermore, if Boxer Capital, 
Baker  Brothers,  or  any  other  of  our  major  shareholders  determine  to  exit  from  the  industry  or  from  their  holdings  in  us,  for 
whatever reason, the impact on our share price could be detrimental over a prolonged period of time.

Our  bylaws,  as  amended  (our  “Bylaws”)  provide  that  the  Court  of  Chancery  of  the  State  of  Delaware  is  the 
exclusive forum for certain disputes between us and our shareholders, which could limit our shareholders’ ability to obtain 
a favorable judicial forum for disputes with us or our directors, officers or employees.

Our Bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the 
following  types  of  actions  or  proceedings  under  Delaware  statutory  or  common  law:  (i)  any  derivative  action  or  proceeding 
brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors or officers to 
our company or our shareholders, (iii) any action asserting a claim against our company arising pursuant to any provision of the 
Delaware  General  Corporation  Law  or  our  amended  and  restated  certificate  of  incorporation  or  Bylaws,  or  (iv)  any  action 
asserting a claim against our company governed by the internal affairs doctrine. This choice of forum provision does not apply 
to suits brought to enforce a duty or liability created by the Securities Act of 1933, as amended, or the Exchange Act, or any 
other claim for which the federal courts have exclusive jurisdiction.  

This choice of forum provision may limit a shareholder’s ability to bring certain claims in a judicial forum that it finds 
favorable for disputes with us or any of our directors, officers, other employees or shareholders, which may discourage lawsuits 
with  respect  to  such  claims,  although  our  shareholders  will  not  be  deemed  to  have  waived  our  compliance  with  federal 
securities laws and the rules and regulations thereunder. If a court were to find this choice of forum provision to be inapplicable 
or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which 
could adversely affect our business and financial condition.

Because  we  do  not  anticipate  paying  any  cash  dividends  on  our  common  stock  in  the  foreseeable  future,  capital 

appreciation, if any, would be our shareholders’ only source of gain.

We have never declared or paid any cash dividends on our common shares, and we currently expect that earnings, if 
any, and cash flow will primarily be retained and used in our operations, including servicing any debt obligations we may have 
now or in the future. Accordingly, although we do not anticipate paying any dividends in the foreseeable future, we may not be 
able to generate sufficient cash flow in order to allow us to pay future dividends on, or make any distributions with respect to 
our common stock. As a result, capital appreciation, if any, of our common stock would be our shareholders’ sole source of 
gain on their investment in our common stock for the foreseeable future.

General Risks

As  a  public  company  in  the  United  States,  we  incur  significant  legal  and  financial  compliance  costs  and  we  are 
subject to the Sarbanes-Oxley Act. We can provide no assurance that we will, at all times, in the future be able to report that 
our internal controls over financial reporting are effective.

Companies that file reports with the SEC, including us, are subject to the requirements of Section 404 of the Sarbanes-
Oxley  Act  of  2002.  Section  404  requires  management  to  establish  and  maintain  a  system  of  internal  control  over  financial 
reporting,  and  annual  reports  on  Form  10-K  filed  under  the  Securities  Exchange  Act  of  1934,  as  amended  (the  “Exchange 
Act”),  must  contain  a  report  from  management  assessing  the  effectiveness  of  a  company’s  internal  control  over  financial 
reporting.  Ensuring  that  we  have  adequate  internal  financial  and  accounting  controls  and  procedures  in  place  to  produce 
accurate  financial  statements  on  a  timely  basis  remains  a  costly  and  time-consuming  effort  that  needs  to  be  re-evaluated 
frequently. Failure on our part to have effective internal financial and accounting controls would cause our financial reporting to 
be unreliable, could have a material adverse effect on our business, operating results, and financial condition, and could cause 
our stock price to decline as a result.

If  we  cannot  conclude  that  we  have  effective  internal  control  over  our  financial  reporting,  or  if  our  independent 
registered public accounting firm is unable to provide an unqualified opinion regarding the effectiveness of our internal control 
over financial reporting, investors could lose confidence in the reliability of our financial statements. Failure to comply with 
reporting requirements could also subject us to sanctions and/or investigations by the SEC, The Nasdaq Global Select Market or 
other regulatory authorities.

35

Furthermore,  shareholder  activism,  the  current  political  environment  and  the  current  high  level  of  government 
intervention  and  regulatory  reform  may  lead  to  substantial  new  regulations  and  disclosure  obligations,  which  may  lead  to 
additional compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate. 
Our  management  and  other  personnel  will  need  to  devote  a  substantial  amount  of  time  to  these  compliance  initiatives. 
Moreover, any new regulations or disclosure obligations may increase our legal and financial compliance costs and will make 
some activities more time-consuming and costly.

Our share price is volatile and may be influenced by numerous factors that are beyond our control.

A  low  share  price  and  low  market  valuation  may  make  it  difficult  to  raise  sufficient  additional  cash  due  to  the 
significant dilution to current shareholders. Market prices for shares of biotechnology and biopharmaceutical companies such as 
ours are often volatile. Factors such as clinical and regulatory developments regarding our products or processes, developments 
regarding potential or future third-party collaborators, announcements of technological innovations, new commercial products, 
patents, the development of proprietary rights by us or by others or any litigation relating to these rights, regulatory actions, 
general  conditions  in  the  biotechnology  and  pharmaceutical  industries,  failure  to  meet  analysts’  expectations,  publications, 
financial results or public concern over the safety of biopharmaceutical and biotechnological products, economic conditions in 
the United States and other countries, terrorism and other factors could have a significant effect on the share price for our shares 
of common stock. Any setback or delay in the clinical development of our programs could result in a significant decrease in our 
share price. In recent years the stock of other biotechnology and biopharmaceutical companies has experienced extreme price 
fluctuations that have been unrelated to the operating performance of the affected companies. There can be no assurance that 
the market price of our shares of common stock will not experience significant fluctuations in the future, including fluctuations 
that are unrelated to our performance. These fluctuations may result due to macroeconomic and world events, national or local 
events, general perception of the biotechnology industry or to a lack of liquidity. In addition, other biotechnology companies’ or 
our competitors’ programs could have positive or negative results that impact their stock prices and their results or experience 
stock  price  fluctuations  that  could  have  a  positive  or  negative  impact  on  our  stock  price,  regardless  whether  such  impact  is 
direct or not.

Shareholders may not agree with our business, scientific, clinical and financial strategy, including additional dilutive 
financings, and may decide to sell their shares or vote against such proposals. Such actions could materially impact our stock 
price. In addition, portfolio managers of funds or large investors can change or change their view on us and decide to sell our 
shares. These actions could have a material impact on our stock price. In order to complete a financing, or for other business 
reasons, we may elect to consolidate our shares of common stock. Investors may not agree with these actions and may sell our 
shares. We may have little or no ability to impact or alter such decisions.

Changes in tax laws or regulations that are applied adversely to us or our future potential customers may have a 

material adverse effect on our business, cash flow, financial condition or results of operations.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which 
could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, rules, regulations 
or ordinances could be interpreted, changed, modified or applied adversely to us. The Biden Administration and Congress have 
proposed  various  U.S.  federal  tax  law  changes,  which  if  enacted  could  have  a  material  impact  on  our  business,  cash  flows, 
financial condition or results of operations. Furthermore, it is uncertain if and to what extent various states will conform federal 
tax  laws.  Future  tax  reform  legislation  could  have  a  material  impact  on  the  value  of  our  deferred  tax  assets,  could  result  in 
significant one-time charges, and could increase our future U.S. tax expense.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our 
equity incentive plans, could result in additional dilution of the percentage ownership of our shareholders and could cause 
our stock price to fall.

We expect that significant additional capital will be needed in the future to continue our planned operations. To the 
extent we raise additional capital by issuing equity securities, our shareholders may experience substantial dilution. We may sell 
common  stock,  convertible  securities  or  other  equity  securities  in  one  or  more  transactions  at  prices  and  in  a  manner  we 
determine  from  time  to  time.  If  we  sell  common  stock,  convertible  securities  or  other  equity  securities  in  more  than  one 
transaction,  investors  may  be  materially  diluted  by  subsequent  sales.  These  sales  may  also  result  in  material  dilution  to  our 
existing shareholders, and new investors could gain rights superior to our existing shareholders.

Pursuant  to  our  2013  Equity  Incentive  Plan  and  our  2013  Employee  Stock  Purchase  Plan  (the  “ESPP”),  our 
management  is  authorized  to  grant  stock  options,  restricted  stock  units  and  other  equity-based  awards  to  our  employees, 
directors and consultants, and to sell our common stock to our employees, respectively. Pursuant to the inducement plan, the 

36

Board of Directors is authorized to grant stock options, restricted stock units and other equity-based awards to new employees 
who satisfy the standards for inducement grants in accordance with the Nasdaq Stock Market LLC listing rules. Any increase in 
the  number  of  shares  outstanding  as  a  result  of  the  exercise  of  outstanding  options,  the  vesting  or  settlement  of  outstanding 
stock  awards,  or  the  purchase  of  shares  pursuant  to  the  ESPP  will  cause  our  shareholders  to  experience  additional  dilution, 
which could cause our stock price to fall.

Item  5.        Market  for  Registrant’s  Common  Equity,  Related  Stockholder  Matters  and  Issuer  Purchases  of  Equity 
Securities 

Our  common  stock  is  listed  under  the  ticker  symbol  “MRTX”  on  The  Nasdaq  Global  Select  Market  since  June  5, 
2018,  and  was  previously  listed  on  The  Nasdaq  Capital  Market  since  July  15,  2013.  Prior  to  that  date,  there  was  no  public 
market for our common stock in the United States as our common stock was listed on the Toronto Stock Exchange.

On February 22, 2022, the last reported sale price for our common stock on The Nasdaq Global Select Market was 

$90.66 per share. 

As of February 22, 2022, we had 13 shareholders of record, which excludes shareholders whose shares were held in 
nominee or street name by brokers. The actual number of common shareholders is greater than the number of record holders, 
and includes shareholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. 
This number of holders of record also does not include shareholders whose shares may be held in trust by other entities. We 
have  never  declared  or  paid  any  cash  dividends  on  our  capital  stock.  We  currently  intend  to  retain  any  future  earnings  for 
funding operations and, therefore, do not anticipate paying any cash dividends in the foreseeable future.

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

You  should  read  the  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  together 
with our consolidated financial statements and related notes thereto included elsewhere in this Annual Report on Form 10-K. 
Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, 
including information with respect to our plans and strategy for our business and related financing, includes forward-looking 
statements  that  involve  risks  and  uncertainties.  As  a  result  of  many  factors,  including  those  factors  set  forth  in  the  “Risk 
Factors” section of this Annual Report on Form 10-K, our actual results could differ materially from the results described in or 
implied by the forward-looking statements contained in the following discussion and analysis.

References  in  the  following  discussion  to  “we,”  “our,”  “us,”  “Mirati”  or  “the  Company”  refer  to  Mirati 

Therapeutics, Inc. and its subsidiaries.

Company Overview

Mirati  Therapeutics,  Inc.  is  a  clinical-stage  oncology  company  developing  novel  therapeutics  to  address  the  genetic 

and immunological promoters of cancer.

We have two KRAS inhibitor programs. Adagrasib is an investigational, selective, specific, potent and orally available 
KRAS  G12C  inhibitor  in  clinical  development  as  a  monotherapy  and  in  combination  with  other  agents.  Adagrasib  is  the 
provisionally filed nonproprietary name for MRTX849. MRTX1133 is an investigational, selective, specific and potent KRAS 
G12D inhibitor in preclinical development. 

Sitravatinib  is  an  investigational  spectrum-selective  kinase  inhibitor  designed  to  potently  inhibit  receptor  tyrosine 

kinases (“RTK”s) and enhance immune responses through the inhibition of immunosuppressive signaling.

MRTX1719 is an internally discovered investigational synthetic lethal PRMT5 inhibitor designed to specifically target 

the PRMT5/methylthioadensoine (MTA) complex in preclinical development.

The Company also has additional preclinical discovery programs of potentially first-in-class and best-in-class product 
candidates  specifically  designed  to  address  mutations  and  tumors  where  few  treatment  options  exist.  We  approach  all  of  our 
programs with a singular focus: to translate our deep understanding of the molecular drivers of cancer into better therapies and 
better outcomes for patients.

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of financial condition and results of operations are based upon our consolidated financial 
statements,  which  have  been  prepared  in  accordance  with  U.S.  generally  accepted  accounting  principles.  The  preparation  of 
these financial statements requires us to make significant estimates and judgments that affect the reported amounts of assets, 
liabilities, revenue and expenses and related disclosures. On an ongoing basis, our actual results may differ significantly from 
our estimates.

While our significant accounting policies are more fully described in Note 2 to our consolidated financial statements 
appearing  elsewhere  in  this  Annual  Report  on  Form  10-K,  we  believe  the  following  accounting  policies  to  be  critical  to  the 
judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

Under  Accounting  Standards  Codification  (“ASC”)  Topic  606  (“Topic  606”),  we  recognize  revenue  when  our 
customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to 
receive in exchange for those goods or services.  To determine revenue recognition for contracts with customers, we perform 
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 entity satisfies a performance obligation.  We only apply the five-step model to contracts 
when  it  is  probable  that  we  will  collect  the  consideration  we  are  entitled  to  in  exchange  for  the  goods  or  services  we 
transfer.  At contract inception, once the contract is determined to be within the scope of Topic 606, we assess the goods or 
services  promised  within  each  contract,  determine  those  that  are  performance  obligations,  and  assess  whether  each  promised 
good or service is distinct.  We then recognize as revenue the amount of the transaction price that is allocated to the respective 

41

performance obligation when (or as) the performance obligation is satisfied.  We utilize key assumptions to determine a stand-
alone selling price for performance obligations, which may include revenue forecasts, expected development timelines, discount 
rates, probabilities of technical and regulatory success and costs for manufacturing clinical supplies.  Because the amount of 
revenue recognized for each performance obligation is determined based upon its relative stand-alone selling price, an increase 
or  decrease  of  10%  in  the  estimated  fair  value  of  each  performance  obligation  would  not  have  a  significant  impact  on  the 
amount of revenue recognized.  

Accrued Research and Development Expenses 

We  accrue  and  expense  clinical  trial  activities  performed  by  third  parties  based  upon  estimates  of  the  proportion  of 
work  completed  over  the  life  of  the  individual  clinical  trial  and  patient  enrollment  rates  in  accordance  with  agreements 
established  with  clinical  research  organizations  (“CROs”)  and  clinical  trial  sites.  We  determine  the  estimates  by  reviewing 
contracts, vendor agreements and purchase orders, and through discussions with internal clinical personnel and external service 
providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services. 
However,  actual  costs  and  timing  of  clinical  trials  are  highly  uncertain,  subject  to  risks  and  may  change  depending  upon  a 
number of factors, including our clinical development plan. 

We  make  estimates  of  our  accrued  expenses  as  of  each  balance  sheet  date  in  our  consolidated  financial  statements 
based on facts and circumstances known to us at that time. If the actual timing of the performance of services or the level of 
effort  varies  from  the  estimate,  we  will  adjust  the  accrual  accordingly.  Nonrefundable  advance  payments  for  goods  and 
services,  including  fees  for  process  development  or  manufacturing  and  distribution  of  clinical  supplies  that  will  be  used  in 
future  research  and  development  activities,  are  deferred  and  recognized  as  expense  in  the  period  that  the  related  goods  are 
consumed or services are performed. 

Share-Based Compensation Expense

We  measure  and  recognize  compensation  expense  for  share-based  payments  based  on  estimated  fair  value.  We 
estimate  the  fair  value  of  stock  options  granted  using  the  Black-Scholes  option-pricing  model.  The  Black-Scholes  option- 
pricing model requires the use of certain estimates and assumptions that affect the amount of share-based compensation expense 
recognized  in  our  consolidated  financial  statements.  These  assumptions  include  the  expected  volatility  of  our  stock  price, 
expected term of the options, the risk-free interest rate and expected dividend yields. We estimate the fair value of restricted 
stock units using the intrinsic value method. We estimate the fair value of performance stock units, which vest based on the 
achievement  of  pre-established  performance  goals,  using  the  intrinsic  value  method  and  the  probability  that  the  specified 
performance criteria will be met. Share-based compensation is recognized using the graded accelerated vesting method. If any 
of the assumptions used in our calculation change significantly, share-based compensation expense may differ materially from 
what we have recorded in the current period.

License and collaboration revenues

License and collaboration revenues relate to the Zai Agreement under which Zai was granted an exclusive license to 
develop,  manufacture  and  commercialize  adagrasib  in  the  Zai  Licensed  Territory,  the  BeiGene  Agreement  under  which 
BeiGene  was  granted  an  exclusive  license  to  develop,  manufacture  and  commercialize  sitravatinib  in  the  BeiGene  Licensed 
Territory, and the ORIC License Agreement under which we granted to ORIC an exclusive worldwide, sublicensable, royalty-
free license, and certain related know-how, to develop and commercialize small molecule inhibitors of the Company's allosteric 
polycomb repressive complex 2, or PRC2, to ORIC. License and collaboration revenues for the year ended December 31, 2021 
were $72.1 million, and are comprised of $66.6 million of license and collaboration revenues under the Zai Agreement related 
to  the  transfer  of  the  license  and  related  know-how  to  Zai,  $5.0  million  of  development  milestone  revenues  related  to  the 
initiation  of  the  first  pivotal  clinical  trial  in  the  BeiGene  Licensed  Territory,  and  $0.4  million  related  to  the  manufacturing 
supply services agreement with BeiGene. License and collaboration revenues for the year ended December 31, 2020 were $13.4 
million, of which $11.4 million related to the transfer of the license and related know-how to ORIC under the ORIC License 
Agreement, and $2.0 million related to the manufacturing supply services agreement with BeiGene.

Research and Development Expenses

Research and development expenses consist primarily of:

•

•

•

•

•

salaries and related expenses for personnel, including expenses related to stock options, or other share-based 
compensation granted to personnel in development functions;

fees  paid  to  external  service  providers  such  as  CROs  and  contract  manufacturing  organizations  related  to 
clinical  trials,  including  contractual  obligations  for  clinical  development,  clinical  sites,  manufacturing  and 
scale-up, and formulation of clinical drug supplies; 

fees  paid  to  contract  service  providers  related  to  drug  discovery  efforts  including  chemistry  and  biology 
services;

license fees paid in connection with our early discovery efforts; and

costs for allocated facilities and depreciation of equipment.

We record research and development expenses as incurred. 

Our research and development efforts during the years ended December 31, 2021 and 2020 were focused primarily on 
our  clinical  development  programs  and  our  preclinical  programs.  The  following  table  summarizes  our  research  and

Research and development expenses for the year ended December 31, 2021 were $508.6 million compared to $299.3 
million during the year ended December 31, 2020. The increase of $209.2 million during the year ended December 31, 2021 
relates  to  an  increase  in  third-party  research  and  development  expenses  of  $129.3  million,  an  increase  in  salaries  and  other 
employee related expense of $36.6 million, an increase in share-based compensation expense of $20.5 million, and an increase 
in  other  research  and  development  costs  of  $23.0  million.  The  increase  in  third-party  research  and  development  expense 
primarily  relates  to  an  increase  in  expenses  associated  with  the  development  of  adagrasib  of  $102.8  million,  sitravatinib  of 
$11.5 million and preclinical and early discovery programs of $16.1 million. The increase in expenses associated with adagrasib 
relates  to  the  ongoing  clinical  trials,  which  include  Phase  1/2,  Phase  2  and  Phase  3  clinical  trials.  The  costs  are  comprised 
largely  of  manufacturing  expenses,  including  manufacturing  costs  related  to  registrational  manufacturing  batches,  CRO  fees 
and  other  clinical  trial-related  expenses.  The  increase  in  expenses  associated  with  the  development  of  sitravatinib  relates  to 
increased investigator payment expenses and CRO fees to support the expansion of existing and new sitravatinib clinical trials. 
The increase in preclinical and early discovery costs is primarily due to increased contracted research and development services 
to support our early discovery efforts. The increase in salaries and other employee related expense of $36.6 million is primarily 
due to an increase in the number of research and development employees during the year ended December 31, 2021 compared 
to the same period in 2020. The increase in share-based compensation of $20.5 million is due to an increase in the fair value of 
equity awards granted and an increase in headcount during the year ended December 31, 2021 compared to the same period in 
2020. The increase in other research and development costs of $23.0 million is primarily due to increases in costs associated 
with professional and consulting services, rent and software license.  

At this time, due to the risks inherent in the clinical development process and product development programs we are 
unable  to  estimate  with  any  certainty  the  costs  we  will  incur  in  the  continued  development  of  adagrasib  and  sitravatinib, 
MRTX1719,  MRTX1133  and  any  of  our  other  preclinical  and  early  discovery  programs.  The  process  of  conducting  clinical 
trials necessary to obtain regulatory approval and manufacturing scale-up to support expanded development and potential future 
commercialization is costly and time consuming. Any failure by us or delay in completing clinical trials, manufacturing scale 
up or in obtaining regulatory approvals could lead to increased research and development expense and, in turn, have a material 
adverse  effect  on  our  results  of  operations.  We  expect  that  our  research  and  development  expenses  may  increase  if  we  are 
successful in advancing adagrasib, sitravatinib, MRTX1719 and MRTX1133 or any of our other preclinical programs into more 
advanced stages of clinical development.

General and Administrative Expenses

General  and  administrative  expenses  consist  primarily  of  salaries  and  related  benefits,  including  share-based 
compensation,  related  to  our  executive,  finance,  legal,  commercial  and  support  functions.  Other  general  and  administrative 
expenses include professional fees for auditing, tax, consulting and patent-related services, rent and utilities and insurance.

General and administrative expenses for the year ended December 31, 2021 were $136.7 million compared to $83.4 
million for the same period in 2020. The increase of $53.3 million is primarily due to an increase in salaries and other employee 
related  expense  of  $15.8  million,  an  increase  in  professional  services  expense  of  $14.9  million,  an  increase  in  facilities, 
insurance and other expense of $10.1 million, an increase in share-based compensation expense of $7.2 million, and an increase 
in sponsorship agreements expense of $5.3 million. The increase in salaries and other employee related expense is primarily due 
to an increase in the number of general and administrative employees during the year ended December 31, 2021 compared to 
the same period in 2020, and is due to growth driven by commercial readiness activities. The increase in professional services 
expense is primarily due to an increase in commercial costs as we prepare for a potential product launch and includes market 
research and professional consulting fees. The increase in facilities, insurance and other expense is primarily due to our new 
corporate headquarters, the size of which is nearly twice that of our former headquarters at an increased cost per square foot, 
increased  software  licensing  costs  and  expensed  equipment  due  to  increased  headcount,  as  well  as  increased  director’s  and 
officer’s liability insurance expense. The increase in share-based compensation expense is due to an increase in the fair value of 
equity awards granted and an increase in headcount during the year ended December 31, 2021 compared to the same period in 
2020. The increase in sponsorship agreements expense is primarily due to a $4.0 million research grant made in the first quarter 
of 2021.

Other (Expense) Income, Net

Other (expense) income, net for the year ended December 31, 2021 was an expense of $5.3 million compared to an 
income  of $11.4 million for the same period in 2020. The decrease of $16.7 million was primarily due to the change  in  fair 
value on the long-term investment in ORIC Pharmaceuticals, Inc., which was acquired in 2020 in connection with the ORIC 
License Agreement, and a decrease in interest income primarily due to lower interest rates.

44

Income Tax Expense

Income tax expense for the year ended December 31, 2021 was $3.3 million and related to foreign income taxes as a 

result of the upfront payment received from Zai in July 2021.

A summary of our Results of Operation for the year ended December 31, 2019 may be found in our Annual Reports on 

Form 10-K, filed with the SEC on February 25, 2021 and February 26, 2020.

Liquidity and Capital Resources

At  December  31,  2021,  we  had  $1.5  billion  of  cash,  cash  equivalents  and  short-term  investments  compared  to  $1.4 
billion  at  December  31,  2020.  In  November  2021,  we  completed  a  public  offering  of  our  common  stock  that  generated  net 
proceeds of $474.7 million. In July 2021, we received net proceeds of $63.4 million for the up-front fee in connection with the 
Zai Agreement. In July 2021, we entered into an amended and restated sales agreement pursuant to which we may, from time to 
time, sell shares of our common stock having an aggregate offering price of up to $500.0 million; as of December 31, 2021, no 
shares  have  been  sold  in  connection  with  this  amended  and  restated  sales  agreement.  During  2020,  we  completed  public 
offerings of our common stock that generated total net proceeds of $1.2 billion. In 2019, we completed public offerings of our 
common  stock  that  generated  net  proceeds  of  $327.8  million.  Based  on  our  current  and  anticipated  level  of  operations,  we 
believe that our cash, cash equivalents and short-term investments will be sufficient to meet our anticipated obligations for at 
least one year from the date this Annual Report on Form 10-K is filed with the SEC.

It  can  take  a  significant  amount  of  time  and  capital  resources  to  successfully  complete  all  stages  of  research  and 
development  and  commercialization  of  a  product  candidate.  The  length  of  time  and  funding  required  cannot  be  accurately 
estimated  as  it  varies  substantially  according  to  the  type,  complexity,  novelty  and  intended  use  of  a  product  candidate.  The 
funding necessary to execute product development and commercialization is uncertain and we are unable to accurately predict 
when or if we will be able to achieve or maintain profitability. The timing and amount of our operating expenditures, and future 
capital requirements will depend on many factors, including:

•

•

•

•

•

the success of our commercialization efforts and market acceptance of adagrasib and other drug product candidates;

the timing and outcome of regulatory review of adagrasib and other drug product candidates;

continued progress in our research and development and clinical development programs;

the cost of manufacturing clinical supply for our clinical trials and commercial manufacturing; and

addition and retention of key research and development and commercial, including sales and marketing, personnel.

To  date,  we  have  funded  our  operations  primarily  through  the  sale  of  our  common  stock,  pre-funded  warrants  to 
purchase our common stock, and to a lesser extent through up-front payments, research funding and milestone payments under 
collaborative  arrangements.  Since  inception,  we  have  primarily  devoted  our  resources  to  funding  research  and  development 
programs,  including  discovery  research,  preclinical  and  clinical  development  activities,  as  well  as  costs  associated  with 
commercial  launch  preparedness  activities.  To  fund  future  operations,  we  will  likely  need  to  raise  additional  capital.  The 
amount and timing of future funding requirements will depend on many factors, including the timing and results of our ongoing 
development efforts, the potential expansion of our current development programs, potential new development programs and 
related  general  and  administrative  support.  We  anticipate  that  we  will  seek  to  fund  our  operations  through  public  or  private 
equity  or  debt  financings  or  other  sources,  such  as  potential  collaboration  agreements.  We  cannot  make  assurances  that 
anticipated  additional  financing  will  be  available  to  us  on  favorable  terms,  or  at  all.  Although  we  have  previously  been 
successful in obtaining financing through our equity securities offerings, there can be no assurance that we will be able to do so 
in  the  future.  As  a  result  of  the  COVID-19  pandemic  and  actions  taken  to  slow  its  spread,  the  global  credit  and  financial 
markets  have  experienced  extreme  volatility,  including  in  liquidity  and  credit  availability,  declines  in  consumer  confidence, 
declines in economic growth, and uncertainty about economic stability. There can be no assurance that deterioration in credit 
and  financial  markets  and  confidence  in  economic  conditions  will  not  occur.  If  equity  and  credit  markets  deteriorate,  it  may 
make any necessary debt or equity financing more difficult to obtain, more costly and/or more dilutive.

(1) On June 30, 2020, the Company entered into an amended and restated lease agreement (the “Amended and Restated Lease”) for office and laboratory space 
located in San Diego, California, for the Company’s new corporate headquarters. The Amended and Restated Lease supersedes in its entirety the original lease 
agreement for the Company’s future corporate headquarters dated as of August 22, 2019. The Amended and Restated Lease has a lease term of approximately 
12 years. The Company has an early termination right 7 years into the lease term, in which the total contractual obligation would be reduced by $41.1 million.

We enter into contracts in the normal course of business with clinical sites for the conduct of clinical trials, CROs for 
clinical research studies, professional consultants for expert advice and other vendors for clinical supply manufacturing or other 
services. These contracts generally provide for termination on notice, and therefore are cancelable contracts and not included in 
the table of contractual obligations and commitments.

Item 7A.     Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

Some  of  our  short-term  investments  have  market  risk  in  that  a  change  in  prevailing  interest  rates  may  cause  the 
principal amount of the investment to fluctuate. Financial instruments that potentially subject us to significant concentrations of 
credit  risk  consist  primarily  of  cash,  cash  equivalents  and  short-term  investments.  We  invest  our  excess  cash  primarily  in 
commercial  paper  and  debt  instruments  of  financial  institutions,  corporations,  U.S.  government-sponsored  agencies  and  the 
U.S.  Treasury.  We  mitigate  credit  risk  by  maintaining  a  well-diversified  portfolio  and  limiting  the  amount  of  investment 
exposure as to institution, maturity and investment type. We invest our excess cash in accordance with our investment policy. 

Because  of  the  short-term  maturities  of  our  cash  equivalents  and  short-term  investments,  we  do  not  believe  that  an 
increase in market rates would have any significant impact on the realized value of our investments. If a 10% change in interest 
rates were to have occurred on December 31, 2021, this change would not have had a material effect on the fair value of our 
investment portfolio as of that date.

Effects of Inflation

We do not believe that inflation and changing prices 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 

As  required  by  Rule  13a-15(b)  and  Rule  15d-15(b)  of  the  Exchange  Act,  our  management,  including  our  principal 
executive officer and our principal financial officer, conducted an evaluation as of the end of the period covered by this Annual 
Report on Form 10-K of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in 
Exchange Act Rule 13a-15(e) and 15d-15(e)). Based on that evaluation, management has concluded that as of December 31, 
2021, the Company’s disclosure controls and procedures were  effective at the reasonable assurance level and we believe the 
consolidated  financial  statements  included  in  this  Form  10-K  for  the  year  ended  December  31,  2021  present,  in  all  material 
respects, our financial position, results of operations, comprehensive loss and cash flows for the periods presented in conformity 
with U.S. generally accepted accounting principles.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as 
such term is defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed under the 
supervision  and  with  the  participation  of  our  management,  including  our  principal  executive  officer  and  principal  financial 
officer,  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 of America. 
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. Therefore, 
even  those  systems  determined  to  be  effective  can  provide  only  reasonable  assurance  with  respect  to  financial  statement 
preparation and presentation.

As of December 31, 2021, our management assessed the effectiveness of our internal control over financial reporting 
using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-
Integrated  Framework  (2013  Framework).  Based  on  this  assessment,  our  management  concluded  that,  as  of  December  31, 
2021, our internal control over financial reporting was effective based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2021 has been audited by Ernst & 

Young LLP, an independent registered public accounting firm, as stated in its report, which is included herein.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant 
to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the quarter ended December 31, 2021 that materially affected, or 
are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of Mirati Therapeutics, Inc.

Opinion on Internal Control Over Financial Reporting 

We have audited Mirati Therapeutics, Inc.’s internal control over financial reporting as of December 31, 2021, based on criteria 
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) (the COSO criteria). In our opinion, Mirati Therapeutics, Inc. (the Company) maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of Mirati Therapeutics, Inc. as of December 31, 2021 and 2020, the related 
consolidated statements of operations and comprehensive loss, changes in shareholders’ equity and cash flows for each of the 
three years in the period ended December 31, 2021, and the related notes and our report dated February 28, 2022 expressed an 
unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report 
on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control 
over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a 
reasonable basis for our opinion.

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) 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 (3) 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. 

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.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of Mirati Therapeutics, Inc.

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Mirati Therapeutics, Inc. (the Company) as of December 31, 
2021 and 2020, the related consolidated statements of operations and comprehensive loss, changes in shareholders’ equity and 
cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as 
the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material 
respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash 
flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting 
principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(2013 framework), and our report dated February 28, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error or fraud. Our audits 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. We believe that our audits provide a reasonable basis for our opinion. 

Critical Audit Matter 

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: (1) relates to accounts or disclosures that 
are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The 
communication of the critical audit matter does not alter in any way our opinion on the consolidated 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.

58

Description of 
the Matter

Accrued research and development expenses
At December 31, 2021, the Company incurred $508.6 million for research and development expenses and 
accrued $76.3 million for research and development expenses. As described in Note 2 to the consolidated 
financial statements, the Company records accruals for estimated costs of research and development activities, 
including contract services for clinical trials and related clinical manufacturing costs. Clinical trial activities 
performed by third parties are accrued and expensed based upon estimates of the proportion of work 
completed over the life of the individual clinical trial and patient enrollment rates in accordance with 
agreements established with Clinical Research Organizations (“CROs”) and clinical trial sites. Estimates are 
determined by reviewing contracts, vendor agreements and purchase orders, and through discussions with 
internal clinical personnel and external service providers as to the progress or stage of completion of trials or 
services and the agreed-upon fee to be paid for such services.

Auditing management’s accounting for accrued research and development expenses, for which the Company 
has either not been invoiced or has not received information on the actual costs incurred, was especially 
challenging as evaluating the progress or stage of completion of the activities under the Company’s research 
and development agreements is dependent upon information from internal clinical personnel and third party 
service providers and involves a high volume of data which is tracked in spreadsheets and other end user 
computing programs.

How We 
Addressed the 
Matter in Our 
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the 
accounting for accrued research and development expenses.  For example, we tested controls over 
management’s assessment and measurement of estimated accrued costs, including data inputs for study 
progress and remaining stages of completion under each study.

To test the completeness of the Company’s accrued research and development expenses, we obtained 
supporting evidence of the research and development activities performed for significant clinical trials. We 
attended internal clinical trial and project status meetings with accounting and clinical project managers to 
inspect the status of significant research and development activities. To assess the appropriate measurement of 
accrued research and development costs, our audit procedures included, among others, obtaining and 
inspecting significant agreements and agreement amendments, and testing a sample of transactions and 
comparing the costs against related invoices and contracts. We also tested a sample of subsequent payments to 
evaluate the completeness of the accrued expenses and compared the results to the current year accrual.

We have served as the Company’s auditor since 2014.

Notes to Consolidated Financial Statements

1.  Description of Business

Mirati Therapeutics, Inc. (“Mirati” or the “Company”) is a clinical-stage oncology company developing product 
candidates to address the genetic and immunological promoters of cancer. The Company was incorporated under the laws of the 
State of Delaware on April 29, 2013 as Mirati Therapeutics, Inc. and is located in San Diego, California. The Company has a 
wholly owned subsidiary in Canada, MethylGene, Inc. (“MethylGene”), a wholly owned subsidiary in the Netherlands (“Mirati 
Therapeutics B.V.”) and operates in the United States. The Company’s common stock has been listed on the Nasdaq Global 
Select Market since June 5, 2018, and was previously listed on the Nasdaq Capital Market since July 15, 2013, under the ticker 
symbol “MRTX.”

2. Summary of Significant Accounting Policies

Basis of Presentation

These consolidated financial statements are prepared in accordance with accounting principles generally accepted in 
the  United  States  (“U.S.  GAAP”).  These  consolidated  financial  statements  include  the  accounts  of  the  Company  and 
MethylGene  and  Mirati  Therapeutics  B.V.  All  significant  inter-company  transactions,  balances  and  expenses  have  been 
eliminated upon consolidation.

Mirati was incorporated under the laws of the State of Delaware on April 29, 2013. On May 8, 2013, the Company’s 
Board  of  Directors  approved  and  the  Company  entered  into  an  arrangement  agreement  with  MethylGene  and  MethylGene 
became a wholly-owned subsidiary. On August 3, 2021, Mirati Therapeutics B.V. was formed in Amsterdam, Netherlands, and 
became a wholly-owned subsidiary.

These consolidated financial statements are presented in United States (“U.S.”) Dollars, which is also the functional 

currency of the Company.

Use of Estimates

The  preparation  of  the  Company’s  consolidated  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 at the date of the financial statements and the reported amounts of revenues and expenses during 
the reporting period. 

Reported  amounts  and  note  disclosures  reflect  the  overall  economic  conditions  that  are  most  likely  to  occur  and 
anticipated  measures  management  intends  to  take.  Actual  results  could  differ  materially  from  those  estimates.  Estimates  and 
assumptions are reviewed quarterly. Any revisions to accounting estimates are recognized in the period in which the estimates 
are revised and in any future periods affected.

Cash, Cash Equivalents and Short-term Investments

Cash and cash equivalents consist of cash and highly liquid securities with original maturities at the date of acquisition 
of ninety days or less. Investments with an original maturity of more than ninety days are considered short-term investments 
and have been classified by management as available-for-sale. These investments are classified as current assets, even though 
the  stated  maturity  date  may  be  one  year  or  more  beyond  the  current  consolidated  balance  sheet  date,  which  reflects 
management’s intention to use the proceeds from sales of these securities to fund its operations, as necessary. Such investments 
are carried at fair value, and the unrealized gains and losses are reported as a component of accumulated other comprehensive 
income in shareholders’ equity until realized. Realized gains and losses from the sale of available-for-sale securities, if any, are 
determined on a specific identification basis.  

Concentration of Credit Risk

The  Company  invests  its  excess  cash  in  accordance  with  its  investment  policy.  The  Company’s  investments  are 
comprised  primarily  of  commercial  paper  and  debt  instruments  of  financial  institutions,  corporations,  U.S.  government-
sponsored  agencies  and  the  U.S.  Treasury.  The  Company  mitigates  credit  risk  by  maintaining  a  diversified  portfolio  and 

64

limiting  the  amount  of  investment  exposure  as  to  institution,  maturity  and  investment  type.  Financial  instruments  that 
potentially subject the Company to significant credit risk consist principally of cash equivalents and short-term investments.

Revenue Recognition

The Company recognizes revenue in connection with certain collaboration and license agreements in accordance with 
the  guidance  of  Revenue  From  Contracts  With  Customers,  Accounting  Standards  Codification  (“ASC”)  Topic  606  (“Topic 
606”). Under Topic 606, the Company recognizes revenue when its customer obtains control of promised goods or services, in 
an  amount  that  reflects  the  consideration  that  the  entity  expects  to  receive  in  exchange  for  those  goods  or  services.    To 
determine  revenue  recognition  for  arrangements  the  Company  determines  are  within  the  scope  of  Topic  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 only applies the five-
step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods 
or services it transfers to the customer.  At contract inception, once the contract is determined to be within the scope of Topic 
606,  the  Company  assesses  the  goods  or  services  promised  within  each  contract  and  determines  those  that  are  performance 
obligations,  and  assesses  whether  each  promised  good  or  service  is  distinct.    The  Company  then  recognizes  as  revenue  the 
amount  of  the  transaction  price  that  is  allocated  to  the  respective  performance  obligation  when  (or  as)  the  performance 
obligation is satisfied.

Property and Equipment, Net 

Property and equipment is stated at historical cost less accumulated depreciation. Historical cost includes expenditures 
that  are  directly  attributable  to  the  acquisition  of  the  items.  All  repairs  and  maintenance  are  charged  to  consolidated  net  loss 
during the financial period in which they are incurred.

Depreciation of property and equipment is calculated using the straight-line method over the estimated useful lives of 

the assets, as follows:

Computer equipment     .................................................................................... 3 years
Office and other equipment     .......................................................................... 6 years
Laboratory equipment    ................................................................................... 6 years
Leasehold improvements .............................................................................. The lesser of the lease term or the life of the asset

Upon  disposal  or  impairment  of  property  and  equipment,  the  cost  and  related  accumulated  depreciation  is  removed 

from the consolidated financial statements and the net amount, less any proceeds, is included in consolidated net loss.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that 
the  carrying  value  of  an  asset  may  not  be  recoverable.  If  such  circumstances  are  determined  to  exist,  an  estimate  of 
undiscounted  future  cash  flows  produced  by  the  long-lived  asset,  including  its  eventual  residual  value,  is  compared  to  the 
carrying value to determine whether impairment exists. In the event that such cash flows are not expected to be sufficient to 
recover  the  carrying  amount  of  the  assets,  the  assets  are  written-down  to  their  estimated  fair  values.  Fair  value  is  estimated 
through discounted cash flow models to project cash flows from the asset. The Company recognized no impairment charges for 
the years ended December 31, 2021, 2020 and 2019.

Share-Based Compensation Expense

The Company measures and recognizes compensation expense for share-based payments based on estimated fair value 
as of the grant date. The fair value of restricted stock units is determined using the intrinsic value method. The fair value of 
performance stock units, which vest based on the achievement of pre-established performance goals, is determined using the 
intrinsic value method and the probability that the specified performance criteria will be met. The fair value of stock options is 
determined using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use of certain 
estimates  and  assumptions  that  affect  the  amount  of  share-based  compensation  expense  recognized  in  the  Company’s 
consolidated  financial  statements.  These  assumptions  include  the  expected  volatility  of  the  Company’s  stock  price,  expected 
term of the options, the risk-free interest rate and expected dividend yields. Share-based compensation expense is recognized 
using the graded accelerated vesting method.

65

Research and Development Expenses

Research and development expenses are charged to consolidated net loss in the period in which they are incurred and 
are comprised of the following types of costs incurred in performing research and development activities: contract services for 
clinical trials and related clinical manufacturing costs, salaries and benefits including share-based compensation expense, costs 
for allocated facilities and depreciation of equipment and license fees paid in connection with the Company’s early discovery 
efforts.

General and Administrative Expenses

General  and  administrative  expenses  consist  primarily  of  salaries  and  related  benefits,  including  share-based 
compensation  expense,  related  to  the  Company’s  executive,  finance,  legal,  commercial  and  support  functions.  Other  general 
and administrative expenses include professional fees for auditing, tax, consulting and patent-related services, rent and utilities 
and insurance. 

Leases

The Company determines if an arrangement is a lease at inception. Lease right-of-use assets represent the Company's 
right  to  use  an  underlying  asset  for  the  lease  term  and  lease  liabilities  represent  the  Company's  obligation  to  make  lease 
payments  arising  from  the  lease.  For  operating  leases  with  an  initial  term  greater  than  12  months,  the  Company  recognizes 
operating  lease  right-of-use  assets  and  operating  lease  liabilities  based  on  the  present  value  of  lease  payments  over  the  lease 
term at the commencement date. Operating lease right-of-use assets are comprised of the lease liability plus any lease payments 
made  and  excludes  lease  incentives.  Lease  terms  include  options  to  renew  or  terminate  the  lease  when  the  Company  is 
reasonably certain that the renewal option will be exercised or when it is reasonably certain that the termination option will not 
be  exercised.  For  the  Company's  operating  leases,  if  the  interest  rate  used  to  determine  the  present  value  of  future  lease 
payments it not readily determinable, the Company estimates its incremental borrowing rate as the discount rate for the lease. 
The Company's incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar 
terms and payments, and in similar economic environments. Lease expense for lease payments is recognized on a straight-line 
basis over the lease term. The Company has elected the practical expedient to not separate lease and non-lease components.

Income Taxes

Income  taxes  have  been  accounted  for  using  the  asset  and  liability  method.  Under  the  asset  and  liability  method, 
deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial 
carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. 
Deferred tax assets and liabilities are measured using enacted tax rates applicable to taxable income in the years in which those 
temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax 
rates is recognized in net loss in the period that includes the enactment date. A valuation allowance against deferred tax assets is 
recorded if, based upon the weight of all available evidence, it is more likely than not that some or all of the deferred tax assets 
will  not  be  realized.  For  uncertain  tax  positions  that  meet  “a  more  likely  than  not”  threshold,  the  Company  recognizes  the 
benefit of uncertain tax positions in the consolidated financial statements.

Segment Reporting

Operating  segments  are  components  of  a  business  where  separate  discrete  financial  information  is  available  for 
evaluation by the chief operating decision-maker for purposes of making decisions regarding resource allocation and assessing 
performance. To date, the Company and the chief operating decision-maker has viewed its operations and managed its business 
as one segment operating primarily in the United States.

Net Loss per Share

Basic  net  loss  per  share  is  calculated  by  dividing  the  net  loss  by  the  weighted-average  number  of  common  shares 
outstanding during the period, without consideration for common share equivalents as they are anti-dilutive. Diluted net loss per 
share is computed by dividing the net loss by the weighted-average number of common shares and common share equivalents 
outstanding  for  the  period,  as  well  as  certain  shares  that  are  contingently  issuable.  Common  share  equivalents  outstanding, 
determined using the treasury stock method, are comprised of shares that may be issued under the Company’s stock option and 
warrant agreements, as well as restricted stock units and performance stock units.

66

The following table presents the weighted average number of common share equivalents, calculated using the treasury 
stock method, as well as certain shares that are contingently issuable, not included in the calculation of diluted net loss per share 
due to the anti-dilutive effect of the securities:

The Company has classified all of its short-term investments as available-for-sale as the sale of such securities may be 
required prior to maturity to implement management strategies, and accordingly, carries these investments at fair value. As of 
December  31,  2021,  and  December  31,  2020,  aggregated  gross  unrealized  losses  of  available-for-sale  investments  were  not 
material, and accordingly, no allowance for credit losses was recorded.

As of December 31, 2021, the Company held 588,235 shares of ORIC Pharmaceuticals, Inc. (“ORIC”) common stock 
subject to certain transfer restrictions. The shares held by the Company are measured at fair value at each reporting period based 
on the closing price of ORIC’s common stock on the last trading day of each reporting period, adjusted for a discount for lack 
of marketability, with any unrealized gains and losses recorded in other (expense) income, net in the Company’s consolidated 
statements of operations and comprehensive loss. See Note 4 for further details.

4. Fair Value Measurements

The Company has certain financial assets and liabilities recorded at fair value which have been classified as Level 1, 2 

or 3 within the fair value hierarchy as described in the accounting standards for fair value measurements. 

The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received 
for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for the asset or liability 
in an orderly transaction between market participants on the measurement date. Market participants are buyers and sellers in the 
principal  market  that  are  (i)  independent,  (ii)  knowledgeable,  (iii)  able  to  transact,  and  (iv)  willing  to  transact.  The  guidance 
prioritizes the inputs used in measuring fair value into the following hierarchy:

•

•

•

Level 1-  Quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2-  Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and

Level 3-  Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its 
own assumptions about the assumptions that market participants would use in pricing.

The Company’s investments in Level 1 assets are valued based on publicly available quoted market prices for identical 
securities as of December 31, 2021 and 2020. The Company determines the fair value of Level 2 related securities with the aid 
of  valuations  provided  by  third  parties  using  proprietary  valuation  models  and  analytical  tools.  These  valuation  models  and 
analytical  tools  use  market  pricing  or  prices  for  similar  instruments  that  are  both  objective  and  publicly  available,  including 
matrix  pricing  or  reported  trades,  benchmark  yields,  broker/dealer  quotes,  issuer  spreads,  two-sided  markets,  benchmark 
securities,  bids  and/or  offers.  The  Level  3  fair  value  measurement  of  the  Company’s  long-term  investment  in  ORIC 
Pharmaceuticals, Inc., which was acquired in 2020, utilized a combination of the Asian Protective Put Option and Finnerty Put 
Option  fair  value  techniques  with  unobservable  inputs  of  69%  volatility  and  an  expected  term  of  0.1  years  to  determine  the 
discount for lack of marketability of 5.0%. See Note 8 for further details on the license agreement with ORIC Pharmaceuticals, 
Inc. There were no transfers between fair value measurement levels for the years ended December 31, 2021 and 2020. 

The  following  table  presents  the  changes  in  estimated  fair  value  of  the  Company’s  asset  measured  using  significant 

unobservable inputs (Level 3) (in thousands):

8. License and Collaboration Agreements

BeiGene Agreement

Terms of Agreement

On January 7, 2018, the Company and BeiGene Ltd, (“BeiGene”) entered into a Collaboration and License Agreement 
(the  “BeiGene  Agreement”),  pursuant  to  which  the  Company  and  BeiGene  agreed  to  collaboratively  develop  sitravatinib  in 
Asia (excluding Japan and certain other countries), Australia and New Zealand (the “BeiGene Licensed Territory”). Under the 
BeiGene  Agreement,  the  Company  granted  BeiGene  an  exclusive  license  to  develop,  manufacture  and  commercialize 
sitravatinib  in  the  BeiGene  Licensed  Territory,  with  Mirati  retaining  exclusive  rights  for  the  development,  manufacture  and 
commercialization of sitravatinib outside the BeiGene Licensed Territory.

As consideration for the rights granted to BeiGene under the BeiGene Agreement, BeiGene paid the Company a non-
refundable, non-creditable up-front fee of $10.0 million.  BeiGene is also required to make milestone payments to the Company 
of up to an aggregate of $123.0 million upon the first achievement of specified clinical, regulatory and sales milestones. The 
BeiGene Agreement additionally provides that BeiGene is obligated to pay to the Company royalties at tiered percentage rates 
ranging from mid-single digits to twenty percent on annual net sales of licensed products in the BeiGene Licensed Territory, 
subject  to  reduction  under  specified  circumstances.  The  BeiGene  Agreement  also  provides  that  the  Company  will  supply 
BeiGene with sitravatinib for use in BeiGene’s development activities in the BeiGene Licensed Territory.

The BeiGene Agreement will terminate upon the expiration of the last royalty term for the licensed products, which is 
the  latest  of  (i)  the  date  of  expiration  of  the  last  valid  patent  claim  related  to  the  licensed  products  under  the  BeiGene 
Agreement,  (ii)  10  years  after  the  first  commercial  sale  of  a  licensed  product  and  (iii)  the  expiration  of  any  regulatory 
exclusivity as to a licensed product. BeiGene may terminate the BeiGene Agreement at any time by providing 60 days prior 
written notice to the Company. Either party may terminate the BeiGene Agreement upon a material breach by the other party 
that remains uncured following 60 days after the date of written notice of such breach or upon certain bankruptcy events. In 
addition, the Company may terminate the BeiGene Agreement upon written notice to BeiGene under specified circumstances if 
BeiGene challenges the licensed patent rights.

Revenue Recognition

 The Company evaluated the BeiGene Agreement under Topic 606. In determining the appropriate amount of revenue 
to be recognized as the Company fulfills its obligations under the BeiGene Agreement, the Company performed the following 
steps: (i) identified the promised goods or services in the contract; (ii) determined whether the promised goods or services are 
performance obligations including whether they are distinct in the context of the contract; (iii) measured the transaction price, 
including any constraints on variable consideration; (iv) allocated the transaction price to the performance obligations; and (v) 
recognized revenue when (or as) the Company satisfied each performance obligation.   

The Company determined the transaction price was equal to the up-front fee of $10.0 million. The transaction price 
was  allocated  to  the  performance  obligations  on  the  basis  of  the  relative  stand-alone  selling  price  estimated  for  each 
performance obligation.  In estimating the stand-alone selling price for each performance obligation, the Company developed 
assumptions  that  require  judgment  and  included  forecasted  revenues,  expected  development  timelines,  discount  rates, 
probabilities of technical and regulatory success and costs for manufacturing clinical supplies. As such, of the up-front fee, the 
Company allocated $9.5 million to the license of the Company’s intellectual property, bundled with the associated know-how, 
and $0.5 million to the initial obligation to supply sitravatinib for clinical development in the BeiGene Licensed Territory.

Licenses  of  Intellectual  Property.      The  license  to  the  Company’s  intellectual  property,  bundled  with  the 
associated  know-how,  represents  a  distinct  performance  obligation.    The  license  and  associated  know-how 
was  transferred  to  BeiGene  during  the  three  months  ended  March  31,  2018,  therefore  the  Company 
recognized  the  full  revenue  related  to  this  performance  obligation  in  the  amount  of  $9.5  million  during  the 
year  ended  December  31,  2018  as  license  and  collaboration  revenues  in  its  consolidated  statements  of 
operations and comprehensive loss.

Manufacturing  Supply  Services.    The  Company’s  initial  obligation  to  supply  sitravatinib  for  clinical 
development  in  the  BeiGene  Licensed  Territory  represents  a  distinct  performance  obligation.  The 
Company recognizes revenue when BeiGene obtains control of the goods, upon delivery, over the period of 
the obligation, which began in late 2018 and continued into 2021. The Company recognized $0.4 million as 
license  and  collaboration  revenues  for  this  performance  obligation  for  the  year  ended  December  31,  2021. 
The Company recognized $2.0 million for this performance obligation during the year ended December 31, 
2020, of which $1.8 million relates to cost-sharing payments due from BeiGene, and $0.2 million relates to 
recognition from the deferred revenue balance. The Company recognized $3.3 million for this performance 
obligation during the year ended December 31, 2019, of which $3.0 million relates to cost-sharing payments 
due from BeiGene, and $0.3 million relates to recognition from the deferred revenue balance.

The  Company  recorded  a  cost-sharing  receivable  from  BeiGene  within  other  current  assets  on  the 
consolidated balance sheets of $0.3 million and $1.3 million as of December 31, 2021 and 2020, respectively.

Milestone  Payments.    The  Company  is  entitled  to  development  milestones  under  the  agreement.  The 
Company recognized $5.0 million milestone payment related to the initiation of the first pivotal clinical trial 
in the BeiGene Licensed Territory during the year ended December 31, 2021, and did not recognize revenue 
associated with development milestones during the years ended December 31, 2020 or 2019. The Company is 
also  entitled  to  certain  regulatory  milestone  payments  which  are  paid  upon  receipt  of  regulatory  approvals 
within  the  BeiGene  Licensed  Territory.  The  Company  determined  that  as  of  December  31,  2021,  the 
remaining potential milestone payments are probable of significant revenue reversal as their achievement is 
highly  dependent  on  factors  outside  the  Company’s  control.  Therefore,  these  payments  have  been  fully 
constrained and are therefore not recognized as revenue.  At the end of each subsequent reporting period, the 
Company will re-evaluate the probability of achievement of each milestone and any related constraint, and if 
necessary,  adjust  its  estimate  of  the  overall  transaction  price.    Any  such  adjustments  are  recorded  on  a 

71

 
cumulative catch-up basis, which would affect the reported amount of license and collaboration revenues in 
the period of adjustment.

Royalties.    As  the  license  is  deemed  to  be  the  predominant  item  to  which  sales-based  royalties  relate,  the 
Company will recognize revenue when the related sales occur.  No royalty revenue was recognized during the 
years ended December 31, 2021, 2020, or 2019.

Pfizer Agreement

In  October  2014,  the  Company  entered  into  a  drug  discovery  collaboration  and  option  agreement  with  Array 
BioPharma,  Inc.  (“Array,”  acquired  by  Pfizer  Inc.  (“Pfizer”)  during  2019)  whereby  Array  provided  services  to  facilitate  the 
discovery, optimization and development of small molecule compounds that bind and specifically inhibit KRAS G12C. In June 
2017,  the  two  parties  entered  into  a  second,  separate  discovery  collaboration  and  option  agreement  whereby  Array  provided 
services  to  facilitate  the  discovery,  optimization  and  development  of  small  molecule  compounds  that  bind  and  specifically 
inhibit  KRAS  G12D.  Both  agreements  established  an  option  mechanism  which  enabled  the  Company  to  elect  an  exclusive 
worldwide  license  under  the  technology  for  the  development  and  commercialization  of  certain  products  based  on  such 
compounds. 

Under the agreements, following the joint discovery periods which have concluded, the Company executed its options 
to retain exclusive worldwide licenses to develop, manufacture and commercialize inhibitors of KRAS G12C and KRAS G12D, 
including but not limited to, MRTX849 (adagrasib is the provisionally filed name for MRTX849) and MRTX1133. Under each 
agreement,  Pfizer  is  entitled  to  potential  development  milestone  payments  of  up  to  $9.3  million,  and  tiered  sales  milestone 
payments of up to $337.0 million based upon worldwide net sales, and tiered royalties in the high single digits to mid-teens on 
worldwide net sales of products arising from the collaborations. Under the agreements, the Company has incurred $9.5 million 
in development milestone payments from inception through December 31, 2021.

The  royalty  term  for  each  agreement  shall  be  payable  on  a  country-by-country  and  product-by-product  basis,  and 
separately will terminate at the later of (i) the date of expiration of the last valid patent claim within the collaboration patent 
rights or the Pfizer background technology covering such product in the country in which such product is sold at the time of 
such sale, or (ii) 10 years after the first commercial sale of such product in such country. The Company may terminate each 
agreement at any time by providing 60 days prior written notice to Pfizer. Either party may terminate each agreement upon a 
material  breach  by  the  other  party  that  remains  uncured  following  60  days  after  the  date  of  written  notice  of  such  breach  or 
upon certain bankruptcy events. 

For the year ended December 31, 2021, the Company incurred expenses under these agreements with Pfizer of $5.0 
million  related  to  initiation  of  the  first  Phase  3  trial  for  adagrasib.  For  the  year  ended  December  31,  2020,  the  Company 
incurred  expenses  of  $4.8  million,  consisting  of  a  $3.0  million  milestone  payment  for  initiation  of  the  first  Phase  2  trial  for 
adagrasib,  a  $0.3  million  milestone  payment  for  initiation  of  the  first  regulatory  toxicology  study  for  MRTX1133,  and  $1.5 
million in research and development services. For the year ended December 31, 2019, the Company incurred expense of $7.0 
million, consisting of a $1.0 million milestone payment for initiation of the first Phase 1 trial for adagrasib, and $6.0 million in 
research and development services.

ORIC Pharmaceuticals Agreement

Terms of Agreement

On  August  3,  2020,  the  Company  entered  into  a  license  agreement  with  ORIC  Pharmaceuticals,  Inc.  (“ORIC”) 
pursuant to which the Company granted to ORIC an exclusive, worldwide license to develop and commercialize the Company’s 
allosteric  polycomb  repressive  complex  2  (“PRC2”)  inhibitors  for  all  indications  (the  “ORIC  License  Agreement”).  In 
accordance with the terms of the ORIC License Agreement, in exchange for such license, ORIC issued 588,235 shares of its 
common stock (the “Shares”) to the Company on August 3, 2020. The Shares were issued under a stock issuance agreement 
entered into between ORIC and the Company, dated August 3, 2020. During the eighteen-month period following the date of 
the stock issuance agreement, the Company is subject to certain transfer restrictions. ORIC is not obligated to pay the Company 
milestone payments or royalty payments under the ORIC License Agreement.  

Unless terminated earlier, the ORIC License Agreement will continue in effect on a country-by-country and licensed 
product-by-licensed  product  basis  until  the  later  (a)  the  expiration  of  the  last  valid  claim  of  a  licensed  patent  covering  such 
licensed  product  in  such  country  or  (b)  10  years  after  the  first  commercial  sale  of  such  licensed  product  in  such  country. 
Following  the  expiration  of  the  ORIC  License  Agreement,  ORIC  will  retain  its  licenses  under  the  intellectual  property  the 

72

Company licensed to ORIC on a royalty-free basis. The Company and ORIC may each terminate the ORIC License Agreement 
if the other party materially breaches the terms of such agreement, subject to specified notice and cure provisions, or enters into 
bankruptcy or insolvency proceedings. The Company may terminate the agreement if ORIC challenges any of the patent rights 
licensed to ORIC by the Company or if ORIC discontinues development of licensed products for a specified period of time. 
ORIC  also  has  the  right  to  terminate  the  ORIC  License  Agreement  without  cause  by  providing  prior  written  notice  to  the 
Company.

Revenue Recognition

The  Company  accounted  for  the  ORIC  License  Agreement  under  Topic  606  and  identified  the  granting  of  an 
exclusive, worldwide license to develop and commercialize the Company’s allosteric PRC2 inhibitors for all indications as a 
distinct  performance  obligation  since  ORIC  can  benefit  from  the  license  on  its  own  by  developing  and  commercializing  the 
underlying product using its own resources. 

In  determining  the  transaction  price,  the  Company  received  the  Shares  as  non-cash  consideration.  The  Company 
allocated the entire transaction price to the distinct performance obligation described above, and the license and related know-
how was transferred to ORIC during the third quarter of 2020. Therefore, the Company recognized the entire transaction price 
of  $11.4  million  as  license  and  collaboration  revenues  in  its  consolidated  statements  of  operations  and  comprehensive  loss 
during the year ended December 31, 2020.

The Shares are carried at fair value and are recorded on the consolidated balance sheet as a long-term investment. Any 
change  in  fair  value  is  recorded  within  other  (expense)  income,  net  on  the  consolidated  statements  of  operations  and 
comprehensive  loss.  The  value  of  the  long-term  investment  is  determined  by  utilizing  a  Level  3  fair  value  measurement  as 
further described in Note 4.

Zai Agreement

Terms of Agreement

On May 28, 2021, the Company and Zai Lab Ltd. (“Zai”) entered into a Collaboration and License Agreement (the 
“Zai Agreement”), pursuant to which the Company and Zai agreed to collaboratively develop adagrasib in China, Hong Kong, 
Macau and Taiwan (collectively, the “Zai Licensed Territory”). Under the Zai Agreement, the Company granted Zai the rights 
to research, develop, manufacture and exclusively commercialize adagrasib in all indications in the Zai Licensed Territory, with 
the Company retaining exclusive rights for the development, manufacture and commercialization of adagrasib outside the Zai 
Licensed Territory and certain co-commercialization, manufacture, and development rights in the Zai Licensed Territory. Zai is 
obligated to participate in selected global, registration-enabling clinical trials and enroll patients in the Zai Licensed Territory at 
Zai’s expense.

As  consideration  for  the  rights  granted  to  Zai  under  the  Zai  Agreement,  Zai  agreed  to  pay  the  Company  a  non-
refundable,  non-creditable  up-front  fee  of  $65.0  million.  Under  the  Zai  Agreement,  the  Company  is  entitled  to  potential 
development  and  regulatory-based  milestone  payments  of  up  to  $93.0  million,  and  tiered  sales  milestone  payments  of  up  to 
$180.0 million based on net sales in the Zai Licensed Territory. The Zai Agreement additionally provides that Zai is obligated 
to pay to the Company royalties at tiered percentage rates ranging from the high-teens to the low-twenties on annual net sales of 
licensed  products  in  the  Zai  Licensed  Territory,  subject  to  reduction  under  specified  circumstances.  The  Zai  Agreement  also 
provides that the Company will supply Zai with adagrasib for use in Zai’s development activities in the Zai Licensed Territory 
at Zai’s expense.

The Zai Agreement will terminate on a licensed product-by-licensed product basis and on a region-by-region basis in 
the Zai Licensed Territory, upon the later to occur of (i) the date of expiration of the last valid claim covering such licensed 
product  in  such  region,  (ii)  the  date  that  is  ten  years  after  the  date  of  the  first  commercial  sale  in  such  region  and  (iii)  the 
expiration date of any regulatory exclusivity for such licensed product in such region, or for a co-commercialized product on 
the  date  the  parties  agree  to  terminate  such  co-commercialization,  or  in  its  entirety  upon  the  expiration  of  all  payment 
obligations under the Zai Agreement. Zai may terminate the Zai Agreement at any time by providing 12 months’ notice to the 
Company.  Either  party  may  terminate  the  Zai  Agreement  upon  a  material  breach  by  the  other  party  that  remains  uncured  or 
upon  certain  bankruptcy  events.  In  addition,  the  Company  may  terminate  the  Zai  Agreement  if  Zai  challenges  the  licensed 
patent rights.

73

Revenue Recognition

The  Company  evaluated  the  Zai  Agreement  under  Topic  606.  The  Company  determined  that  two  performance 
obligations existed: (1) the license to intellectual property, bundled with the associated know-how and (2) the Company’s initial 
obligation  to  supply  adagrasib  for  clinical  development  in  the  Zai  Licensed  Territory.  At  the  time  it  entered  into  the  Zai 
Agreement, the Company determined the transaction price was equal to $66.6 million, which includes the up-front fee and other 
incidental  amounts.  In  estimating  the  stand-alone  selling  price  for  each  performance  obligation,  the  Company  developed 
assumptions  that  require  judgment  and  included  forecasted  revenues,  expected  development  timelines,  discount  rates, 
probabilities of technical and regulatory success, forecasted costs for manufacturing clinical supplies and cost savings related to 
Zai’s  participation  in  selected  trials.  The  Company  allocated  the  full  transaction  price  to  the  license  to  the  Company’s 
intellectual  property,  bundled  with  the  associated  know-how.  The  Company  concluded  the  variable  payments  related  to  the 
Company’s initial obligation to supply adagrasib for clinical development in the Zai Licensed Territory relate specifically to the 
Company’s efforts to satisfy this performance obligation and the obligation to provide the initial clinical supply approximates 
the stand-alone selling price. Payments under the Zai Agreement are subject to foreign tax withholdings.

Licenses  of  Intellectual  Property.      The  license  to  the  Company’s  intellectual  property,  bundled  with  the 
associated  know-how,  represents  a  distinct  performance  obligation.  The  license  and  associated  know-how 
was transferred to Zai during the year ended December 31, 2021, therefore, the Company recognized revenue 
of  $66.6  million  as  license  and  collaboration  revenues  and  $3.3  million  as  income  tax  expense  in  its 
consolidated statements of operations and comprehensive loss during the year ended December 31, 2021.

Manufacturing  Supply  Services.    The  Company’s  initial  obligation  to  supply  adagrasib  for  clinical 
development  in  the  Zai  Licensed  Territory  represents  a  distinct  performance  obligation.  As  such,  the 
Company  will  recognize  revenue  when  Zai  obtains  control  of  the  goods.  No  revenue  related  to  this 
performance  obligation  was  recognized  for  the  year  ended  December  31,  2021.  The  Company  may  also 
become responsible for manufacturing adagrasib for commercial supply and will receive reimbursement that 
approximates stand-alone selling prices.

Milestone Payments.  The Company is entitled to development milestone payments and certain regulatory and 
sales milestone payments which are paid upon achievement of the development milestones, upon receipt of 
regulatory  approvals  and  annual  net  sales  thresholds  within  the  Zai  Licensed  Territory  under  the  Zai 
Agreement. The Company evaluated whether or not the milestones are considered probable of being reached 
and  determined  that  their  achievement  is  highly  dependent  on  factors  outside  of  the  Company’s  control. 
These payments have been fully constrained and therefore are not included in the transaction price. At the end 
of  each  subsequent  reporting  period,  the  Company  will  re-evaluate  the  probability  of  achievement  of  each 
milestone and any related constraint and, if necessary, adjust its estimate of the overall transaction price. Any 
such adjustments will be recorded on a cumulative catch-up basis, which would affect the reported amount of 
license and collaboration revenues in the period of adjustment.

Royalties.    As  the  license  is  deemed  to  be  the  predominant  item  to  which  sales-based  royalties  relate,  the 
Company will recognize revenue when the related sales occur.  No royalty revenue was recognized during the 
year ended December 31, 2021.

Equity Incentive Plan 

The Company has a stock option plan (the “Stock Option Plan”) for the benefit of employees, directors, officers and 
consultants  of  the  Company.  In  May  2013  the  Company’s  Board  of  Directors  adopted  the  2013  Equity  Incentive  Plan  (the 
“2013  Plan”).  The  2013  Plan  was  approved  by  the  Company’s  shareholders  in  connection  with  the  Arrangement.  The 
Company’s  Board  of  Directors  and  shareholders  approved  an  amendment  to  the  2013  Plan  in  2021  to,  among  other  things, 
increase the aggregate number of shares of common stock authorized for issuance under the 2013 Plan by 2.5 million shares. 
The 2013 Plan is a continuation of and successor to the Stock Option Plan and no further grants will be made under the Stock 
Option Plan. As of December 31, 2021, there were approximately 2.6 million shares available to be granted from the 2013 Plan.

In December 2019, the Company’s Board of Directors adopted the Inducement Plan, reserving 417,343 shares of the 
Company’s  common  stock  for  issuance  of  stock  options  and  other  equity-based  awards  to  new  employees  who  satisfy  the 
standards  for  inducement  grants  in  accordance  with  the  Nasdaq  Stock  Market  LLC  listing  rules.  As  of  December  31,  2021, 
there were 121,574 shares available to be issued from the Inducement Plan. 

As  of  December  31,  2021,  share-based  compensation  awards  under  both  the  Stock  Option  Plan  and  the  2013  Plan 
consist of incentive and non-qualified stock options, and restricted stock units. Stock options granted under each of the plans 
must have an exercise price equal to at least 100% of the fair market value of the Company’s common stock on the date of grant 
and generally vest over four years. Stock options granted under the Stock Option Plan had a contractual term of seven years and 
stock options granted under the 2013 Plan have a contractual term of ten years.

The total intrinsic value of stock options exercised was $91.1 million, $121.5 million and $38.6 million for the years 
ended December 31, 2021, 2020, and 2019, respectively. The Company received total cash of $28.0 million, $45.9 million and 
$8.5  million  for  the  exercise  of  options  for  the  years  ended  December  31,  2021,  2020  and  2019,  respectively.  The  total  fair 
value of options vested during the years ended December 31, 2021, 2020 and 2019 was $58.3 million, $52.1 million and $20.4 
million, respectively. Upon option exercise, the Company issues new shares of its common stock. 

The  fair  value  of  options  granted  is  estimated  at  the  date  of  grant  using  the  Black-Scholes  option  pricing  model. 
Forfeitures are accounted for as incurred as a reversal of any share-based compensation expense related to options that will not 
vest. The assumptions used for the specified reporting periods and the resulting estimates of weighted-average estimated fair 
value per share of options granted during those periods are as follows:

Risk-Free Interest Rate - The risk-free interest rate is the rate for periods equal to the expected term of the 
stock option based on U.S. Treasury zero-coupon bonds.  

Dividend Yield - The dividend yield is based on the Company’s history and expectation of dividend payouts. 
The Company has not paid, and does not intend to pay dividends.

Volatility Factor - The expected volatility assumption was determined by examining the historical volatility 
of the Company’s stock. 

Expected Term - The expected term represents the weighted average period the stock options are expected to 
be outstanding.

The  total  compensation  cost  not  yet  recognized  as  of  December  31,  2021  related  to  non-vested  option  awards  was 

$88.8 million which will be recognized over a weighted-average period of 1.3 years.

Restricted Stock Units (“RSUs”)

The Company began issuing RSUs during 2020. The RSUs generally vest annually over four years and are subject to 

continued service. A summary of the Company’s RSU activity for the year ended December 31, 2021 is as follows:

2013 Employee Stock Purchase Plan

In May 2013, the Company’s Board of Directors adopted the 2013 Employee Stock Purchase Plan (the “ESPP”). The 
ESPP was approved by the Company’s shareholders in connection with the Arrangement. In December 2014, the ESPP became 
effective and the first purchase period began. The ESPP permits eligible employees to make payroll deductions to purchase up 
to $25,000 of the Company’s common stock on regularly scheduled purchase dates at a discount. Offering periods under the 
ESPP  are  not  more  than  six  months  in  duration  and  shares  are  purchased  at  85%  of  the  lower  of  the  closing  price  for  the 
Company’s  common  stock  on  the  first  day  of  the  offering  period  or  the  date  of  purchase.  The  ESPP  initially  authorized  the 
issuance  of  300,000  shares  of  the  Company’s  common  stock  pursuant  to  rights  granted  to  employees  for  their  payroll 
deductions. As of December 31, 2021, 192,236 shares have been issued out of the plan.

11.  Employee Benefit Plan

The  Company  has  a  defined  contribution  401(k)  plan  (the  “Plan”)  for  all  employees.  Employees  are  eligible  to 
participate in the Plan if they are at least 21 years of age or older. Under the terms of the Plan, employees may make voluntary 
contributions as a percentage of compensation. During the years ended December 31, 2021 and 2020, the Company matched up 
to 5% of an employee’s earnings, subject to Internal Revenue Service limitations. In 2019, the Company matched up to 4% of 
an employee’s contributions, subject to a limit of $2,500. Expense associated with the Company’s matching contribution totaled 
$2.5 million, $1.3 million, and $0.2 million for the years ended December 31, 2021, 2020, and 2019 respectively.

12.  Income Taxes

The  income  tax  expense  recorded  during  the  year  ended  December  31,  2021,  of  $3.3  million  was  related  to  foreign 
withholding taxes on the up-front fee in connection with the Zai Agreement. The Company had no federal income tax expense 
and immaterial state tax expense for the years ended December 31, 2020 and 2019.

The total valuation allowance increased by $150.7 million for the year ended December 31, 2021. The Company has 
established  a  full  valuation  allowance  against  its  net  deferred  tax  assets  as  of  December  31,  2021  due  to  the  uncertainty 
surrounding the realization of such assets as evidenced by the cumulative losses from operations through December 31, 2021.

For  Canadian  federal  income  tax  purposes,  the  Company’s  Canadian  federal  scientific  research  and  experimental 
development  expenditures  amounted  to  $19.9  million  at  December  31,  2021,  2020  and  2019  and  for  provincial  income  tax

purposes amounted to $21.6 million at December 31, 2021, 2020 and 2019.  As operations in Canada ceased during 2014, no 
expenditures were incurred for the years ended December 31, 2021, 2020 and 2019. These expenditures are available to reduce 
future taxable income and have an unlimited carry forward period. Scientific research and development expenditures are subject 
to  verification  by  the  taxation  authorities,  and  accordingly,  these  amounts  may  vary  by  a  material  amount.  In  addition,  the 
Company has research and development tax credit carryforwards for U.S. federal and state income tax purposes as of December 
31, 2021 of $48.5 million and $16.8 million, respectively. The federal credits will begin to expire in 2033 unless utilized and 
the state credits have an indefinite life. Further, the Company has orphan drug tax credit carryforwards for U.S. federal income 
tax purposes as of December 31, 2021 of $7.2 million. The credits will begin to expire in 2041 unless previously utilized. 

At December 31, 2021, the Company’s net operating loss carry forwards (“NOLs”) for U.S. federal and state income 
taxes were $1.3 billion and $296.4 million, respectively, and the Company’s NOLs for Canadian federal and provincial income 
tax purposes were $79.5 million and $78.9 million, respectively. The NOLs expire as follows (in thousands):

The future utilization of the U.S. federal and state NOL and credit carryforwards to offset future taxable income and 
tax, respectively, may be subject to an annual limitation as a result of ownership changes that may have occurred previously or 
may  occur  in  the  future.  The  Tax  Reform  Act  of  1986  (the  “Act”)  limits  a  company’s  ability  to  utilize  certain  tax  credit 
carryforwards  and  net  operating  loss  carryforwards  in  the  event  of  a  cumulative  change  in  ownership  in  excess  of  50%  (by 
value) as defined in the Act.

During 2017, the Company completed a study to assess whether an ownership change, as defined by Section 382 of 
the Act, had occurred from the Company’s formation through December 31, 2017. The results of the study have been extended 
through December 31, 2021. Based upon the study, the Company determined an ownership change had occurred during 2017, 
causing  the  annual  utilization  of  the  NOL  and  credit  carryforwards  to  be  limited.  The  Company  does  not  believe  any  of  the 
NOL and credit carryforwards generated through December 31, 2021 would expire solely as a result of annual limitations on 
the  utilization  of  those  attributes.  The  Canadian  Federal  and  Provincial  Tax  Acts  maintain  similar  rules  in  the  case  of 
acquisition of control, which may limit the utilization of tax attributes.

The  Company  files  income  tax  returns  in  the  U.S.  (federal  and  state)  and  Canada  (federal  and  provincial).  The 
Company’s U.S. operations have not been audited for any open taxation years. The Company has experienced losses for U.S. 
tax purposes and therefore, the taxation authorities may review any loss year, if and when the losses are utilized.

For Canadian tax purposes, the Company remains subject to federal and provincial audit for the December 31, 2016 
and subsequent taxable years. Where tax years remain open, the Company considers it reasonably possible that issues may be 
raised or tax positions agreed to with the taxation authorities, which may result in increases or decreases of the balance of non-
refundable  investment  tax  credits  (“ITCs”)  and  NOLs.  However,  an  estimate  of  such  increases  and  decreases  cannot  be 
currently made.

If recognized, none of the unrecognized tax positions would impact the Company’s income tax benefit or effective tax 
rate  as  long  as  the  Company’s  net  deferred  tax  assets  remain  subject  to  a  full  valuation  allowance.  The  Company  does  not 
expect any significant increases or decreases to the Company’s unrecognized tax positions within the next 12 months. 

The  Company  recognizes  interest  and  penalties  related  to  unrecognized  tax  benefits  in  income  tax  expense.  The 

Company had no accrual for interest or penalties on tax matters as of December 31, 2021, 2020 and 2019.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted in response to 
the  COVID-19  pandemic.  The  CARES  Act,  among  other  things,  permits  NOL  carryovers  and  carrybacks  to  offset  100%  of 
taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019 and 
2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. Due to 
the Company’s history of net operating losses, the CARES Act did not have a material impact on the Company’s consolidated 
financial statements.

13.  Investment Tax Credits

In prior years, the Company was entitled to claim Canadian federal and provincial ITCs for eligible scientific research 
and  development  expenditures.  The  Company  recorded  ITCs  based  on  management’s  best  estimates  of  the  amount  to  be 
recovered and ITCs claimed are subject to audit by the taxation authorities and accordingly, may vary by a material amount. 
The Company has not recorded federal or provincial ITCs since the year ended December 31, 2013, as the primary operations 
of the Company were moved from Canada to San Diego, California in early 2014.  

The  Company’s  non-refundable  Canadian  federal  ITCs  as  of  December  31,  2021  are  $3.9  million  and  relate  to 
scientific research and development expenditures, which may be utilized to reduce Canadian federal income taxes payable in 
future years. The benefits of the non-refundable Canadian federal ITCs have not been recognized in the financial statements and 
will be recorded as a reduction of tax expense when realized.

14.  Commitments and Contingencies

On June 30, 2020, the Company entered into an amended and restated lease agreement (the “Amended and Restated 
Lease”) for office and laboratory space located in San Diego, California, for the Company’s new corporate headquarters. The 
Amended  and  Restated  Lease  supersedes  in  its  entirety  the  original  lease  agreement  for  the  Company’s  future  corporate 
headquarters  dated  as  of  August  22,  2019.  The  Amended  and  Restated  Lease  has  a  lease  term  of  approximately  12  years 
(“Lease Term”), unless terminated earlier. The Lease Term has an initial abatement period, and the initial base rent payable will 
be approximately $0.6 million per month following the abatement period, which amount will increase by 3% per year over the

Lease  Term.  The  Company  has  also  received  incentives  from  the  landlord  for  tenant  improvements.  During  2020,  the 
underlying  asset  was  available  for  use  by  the  Company  to  construct  tenant  improvements  and  therefore,  the  Lease  Term  is 
considered to have commenced.

The  Amended  and  Restated  Lease  is  considered  to  be  an  operating  lease,  and  the  Amended  and  Restated  Lease 
indicates the interest rate applicable to the lease is 12%, therefore the Company used a discount rate of 12% to calculate the 
present value of its lease payments over the Lease Term. As of December 31, 2021, the consolidated balance sheet includes an 
operating right-of-use asset of $37.7 million and an operating lease liability of $47.2 million, of which $1.3 million is a current 
lease liability and included in other accrued expenses, and $45.9 million is included in non-current lease liability. For the year 
ended December 31, 2021, the Company recorded $7.7 million in operating lease expense.

As of December 31, 2020, the consolidated balance sheet includes an operating right-of-use asset of $39.9 million and 
an  operating  lease  liability  of  $41.9  million.  For  the  year  ended  December  31,  2020,  the  Company  recorded  $0.3  million  in 
operating lease cost.

The Company has an early termination right 7 years into the lease term, in which the total contractual obligation would be reduced by $41.1 million.

San Diego, California. The office space under the lease is the Company’s corporate headquarters. The lease commenced in two 
phases (in July 2014 and March 2015) at a combined total initial monthly rent of $24,100 per month. The leased property is 
subject to a 3% annual rent increase following availability. In addition to such base monthly rent, the Company is obligated to 
pay  certain  customary  amounts  for  its  share  of  operating  expenses  and  facility  amenities.  The  original  lease  provided  for 
expiration on January 31, 2018, and the Company entered into subsequent amendments to the original lease to extend the lease 
term to July 2021 and expand the size of the existing space. All other terms and covenants from the original lease agreement 
remain unchanged.
