PART I

Item 1. Business.

Overview

We are a commercial-stage biopharmaceutical company focused on the development and commercialization of novel small molecule therapeutics for the
treatment  of  patients  with  cancer.  Our  first  FDA-approved  product,  COSELA™  (trilaciclib)  is  the  first  and  only  therapy  indicated  to  proactively  help
protect bone marrow from the damage of chemotherapy (myeloprotection) and is the first innovation in managing myelosuppression in decades. Trilaciclib
was  developed  from  a  technology  platform  that  targets  key  cellular  pathways  including  transient  arrest  of  the  cell  cycle  at  the  G1  phase,  prior  to  the
beginning of DNA replication. Controlled administration and clean G1 arrest reduce hematologic adverse events (AEs) caused by cytotoxic therapy and
may  increase  the  ability  to  receive  longer  treatment  durations.  Transient  CDK4/6  inhibition  also  modulates  multiple  immune  functions  while  allowing
beneficial T cell proliferation which may improve patients’ anti-tumor immune responses. We are exploring the use of trilaciclib in a variety of trials across
multiple tumor types and treatment combinations to optimize these dual benefits of myeloprotection and improved anti-tumor efficacy for patients globally.

We were incorporated under the laws of the State of Delaware in May 2008 under the name “G-Zero Therapeutics, Inc.” In September 2012, we changed
our name to “G1 Therapeutics, Inc.” Our principal executive offices are located at 700 Park Offices Drive, Suite 200, Research Triangle Park, NC 27709,
and our telephone number is (919) 213-9835. 

We manage our operations as a single segment for the purposes of assessing performance and making operating decisions. All of our assets are held in the
United States.

“G1 Therapeutics,” “COSELA” and our logo are our trademarks. All other service marks, trademarks and trade names appearing in this Annual Report are
the  property  of  their  respective  owners.  We  do  not  intend  our  use  or  display  of  other  companies’  trade  names,  trademarks  or  service  marks  to  imply  a
relationship with, or endorsement or sponsorship of us by, these other companies. We shall use “COSELA” when we are referring to our FDA approved
drug and “trilaciclib” when we are referring to our development of COSELA for additional indications. “Myeloprotection” is synonymous with the term
“myelopreservation.”  We used “myelopreservation” in our communications and disclosures prior to the FDA’s approval of trilaciclib (COSELA) and we
now use the term “myeloprotection” following FDA’s approval in order to align more closely with the FDA’s terminology.

Product Portfolio

Our lead compound trilaciclib is a first-in-class therapy designed to help protect against chemotherapy-induced myelosuppression. Trilaciclib helps protect
hematopoietic stem and progenitor cells (“HSPCs”) in the bone marrow by transiently inhibiting CDK4/6 leading to a temporary arrest of susceptible host
cells during chemotherapy in patients. This reduces the duration and severity of neutropenia and other myelosuppressive consequences of chemotherapy. In
addition, trilaciclib may improve anti-tumor efficacy when administered as combination treatment in patients by increasing their ability to receive more
cytotoxic  therapy,  protecting  their  immune  systems  from  damage  caused  by  cytotoxic  therapy,  and  improving  their  immune  responses  by  modulating
multiple immune functions while also allowing beneficial T cell proliferation. On February 12, 2021, trilaciclib (COSELA™) was approved by the U.S.
Food and Drug Administration (“FDA”) to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to
a platinum/etoposide-containing regimen or topotecan-containing regimen for extensive small cell lung cancer (“ES-SCLC”). We continue to explore these
dual benefits of myeloprotection and anti-tumor efficacy across multiple clinical trials.

In 2020, we out-licensed global rights to lerociclib, an internally discovered and differentiated oral CDK4/6 inhibitor designed to enable more effective
treatment combination strategies across multiple oncology indications. We also have intellectual property focused on cyclin-dependent kinase targets.

Rintodestrant is an oral selective estrogen receptor degrader (“SERD”) for the treatment of ER+ breast cancer. We are in the process of evaluating
partnering options for this program.

In 2020, we entered into a global license agreement with ARC Therapeutics, Inc. (“ARC”) for the development and commercialization of an internally
discovered  CDK2  inhibitor  for  all  human  and  veterinary  uses.  ARC  is  currently  granted  an  exclusive,  royalty-bearing,  license  with  the  right  to  grant
sublicenses to one of our solely-owned patent families.

COSELA is a prescription medicine used to help reduce the occurrence of low blood cell counts caused by damage to bone marrow from chemotherapy.
COSELA is used to treat adults taking certain chemotherapies (platinum/etoposide or topotecan) for extensive-stage small cell lung cancer.

COSELA is an injection for intravenous (IV) use given within 4 hours before chemotherapy.

Commercial Product

On February 12, 2021, COSELA™ was approved by the U.S. Food and Drug Administration (“FDA”) to decrease the incidence of chemotherapy-induced
myelosuppression  in  adult  patients  when  administered  prior  to  a  platinum/etoposide-containing  regimen  or  topotecan-containing  regimen  for  extensive
small cell lung cancer (“ES-SCLC”). COSELA became commercially available through our specialty distributor network on March 2, 2021. COSELA is a
first-in-class therapy designed to help protect against chemotherapy-induced myelosuppression. COSELA helps protect hematopoietic stem and progenitor
cells (“HSPCs”) in bone marrow by transiently inhibiting CDK4/6 leading to a temporary arrest of susceptible host cells during chemotherapy in patients
with ES-SCLC. This reduces the duration and severity of neutropenia and other myelosuppressive consequences of chemotherapy.

COSELA is administered intravenously as a 30-minute infusion completed within four (4) hours prior to the start of chemotherapy and is the first and only
FDA-approved  therapy  that  helps  proactively  deliver  multilineage  myeloprotection  to  patients  with  ES-SCLC  being  treated  with  chemotherapy.  The
approval of COSELA is based on data from three (3) randomized, placebo-controlled trials that showed patients receiving COSELA prior to chemotherapy
had clinically meaningful and statistically significant reduction in the duration and severity of neutropenia, reduction of red blood cell transfusions, as well
as improvements in other myeloprotection measures, compared to patients receiving chemotherapy without COSELA.

We  announced  on  March  25,  2021,  that  COSELA  had  been  included  in  two  updated  National  Comprehensive  Cancer  Network®  (“NCCN”)  Clinical
Practice  Guidelines  in  Oncology  (NCCN  Guidelines®):  The  Treatment  Guidelines  for  Small  Cell  Lung  Cancer  and  the  Supportive  Care  Guidelines  for
Hematopoietic Growth Factors. These guidelines document evidence-based, consensus-driven management to ensure that all patients receive preventive,
diagnostic, treatment, and supportive services that are most likely to lead to optimal outcomes. On October 1, 2021, we announced that the permanent J-
code for COSELA that was issued in July 2021 by the Centers for Medicare & Medicaid Services (CMS) is now effective for provider billing for all sites
of care. All hospital outpatient departments, ambulatory surgery centers and physician offices in the United States have one consistent Healthcare Common
Procedure Coding System (HCPCS) code to standardize the submission and payment of COSELA insurance claims across Medicare, Medicare Advantage,
Medicaid  and  commercial  plans.  Our  new  technology  add-on  payment  (NTAP)  for  COSELA,  which  provides  additional  payment  to  inpatient  hospitals
above  the  standard  Medicare  Severity  Diagnosis-Related  Group  (MS-DRG)  payment  amount,  also  became  effective  for  provider  billing  on  October  1,
2021.

In  June  2020,  we  entered  into  a  three-year  co-promotion  agreement  for  COSELA  in  the  United  States  and  Puerto  Rico  with  Boehringer  Ingelheim
Pharmaceuticals, Inc (“BI”). In December 2021, G1 and BI announced that the parties mutually agreed to end the co-promotion agreement for COSELA,
effective March 2022. At that time, we announced that we would hire and deploy a total of 34 oncology sales representatives to accelerate sales activities
and help maximize the adoption of COSELA. As of February 21, 2022, all 34 sales representatives have been hired, trained and deployed.

Trilaciclib Development Pipeline

We are also executing on our tumor-agnostic strategy to evaluate the potential benefits of trilaciclib to patients with other tumors and to generate new data
for trilaciclib in a variety of cytotoxic settings and treatment combinations to maximize its potential for patients in existing and future treatment paradigms.
We currently have five on-going clinical trials: a pivotal trial in 1L colorectal cancer (“CRC”), a pivotal trial in 1L mTNBC, a Phase 2 trial in 1L bladder
cancer with chemotherapy induction and checkpoint inhibitor maintenance, a Phase 2 trial in combination with an antibody-drug conjugate (“ADC”) in
2L/3L mTNBC, and a Phase 2 trial in neoadjuvant TNBC designed to validate trilaciclib’s immune-based mechanism of action (“MOA”). These studies
will evaluate trilaciclib’s dual benefits of proactive multi-lineage myeloprotection and anti-tumor efficacy across tumor types and treatment combinations
and will help inform the design of future additional pivotal studies. We are also conducting extensive preclinical work to assess the additive/synergistic
potential of trilaciclib with a variety of new and emerging therapeutic agents that may be pursued as combination treatments in future clinical trials.

Mechanism of Action - Trilaciclib

Trilaciclib,  a  novel  transient  IV  CDK4/6  inhibitor  has  unique  attributes  including  rapid  onset  from  IV  administration,  potent  and  selective  CDK4  and
CDK6  inhibition  and  a  short  half-life.  Controlled  administration  and  clean  G1  arrest  reduce  hematologic  adverse  events  (“AEs”)  caused  by  cytotoxic
therapy and may increase patients’ abilities to receive longer treatment durations. Transient CDK4/6 inhibition also modulates multiple immune functions
while allowing beneficial T cell proliferation which may improve patients’ anti-tumor immune responses.

Trilaciclib  transiently  blocks  progression  through  the  cell  cycle.  This  provides  benefits  which  manifest  depending  on  the  tumor  type  and  therapeutic
backbone, including: (1) proactive multi-lineage myeloprotection, and (2) potentially improved anti-tumor efficacy.

First, trilaciclib provides proactive multi-lineage myeloprotection by transiently arresting hematopoietic stem and progenitor cells (“HSPCs”), helping to
protect  them  from  damage  caused  by  cytotoxic  therapy  thereby  minimizing  cytopenias  across  neutrophils,  erythrocytes,  and  platelets.  These  proactive
multi-lineage myeloprotection benefits were seen in our three double-blind, placebo-controlled clinical trials in ES-SCLC, where highly myelosuppressive
chemotherapy regimens are administered multiple days in a row. This myeloprotection benefit is being explored as the primary endpoint in our ongoing
PRESERVE 1 trial in 1L colorectal cancer.

Second, trilaciclib may have the ability to improve anti-tumor efficacy through a combination of potential factors, including increasing patients’ ability to
receive  more  cytotoxic  therapy,  protecting  the  immune  system  from  damage  caused  by  cytotoxic  therapy,  and  favorably  modulating  multiple  immune
functions  while  also  allowing  beneficial  T  cell  proliferation.  In  particular,  these  immune  function  improvements  may  include:  (1)  enhancing  T  cell
activation  (via  increased  antigen  presentation  and  secretion  of  IL-2  and  IFNγ),  (2)  favorably  altering  the  tumor  microenvironment  (via  increased
chemokines responsible for trafficking T cells to tumors and reducing the number and function of immunosuppressive cell populations), and (3) improving
long-term immune surveillance (via increased generation of memory CD8+ T cells). A meaningful anti-tumor efficacy benefit was observed in our Phase 2
mTNBC study in which trilaciclib led to a significant improvement in overall survival when administered in combination with chemotherapy compared to
chemotherapy  alone.  We  are  exploring  these  dual  benefits  of  myeloprotection  and  anti-tumor  efficacy  across  a  variety  of  ongoing  Phase  2  and  Phase  3
clinical trials.

Description of Ongoing Clinical Trials - Trilaciclib

Pivotal 1L Colorectal Cancer (CRC)

We are enrolling patients in PRESERVE 1, a randomized, placebo-controlled registrational trial of trilaciclib in colorectal cancer (“CRC”). CRC is a large
indication commonly treated with 5-FU-based chemotherapy. We have extensive preclinical research demonstrating myeloprotection and potential efficacy
in 5-FU-based regimens with trilaciclib. Our ongoing 1L CRC trial is evaluating trilaciclib administered in combination with FOLFOXIRI, which is the
most efficacious chemotherapy regimen in this tumor type but highly myelosuppressive compared with FOLFOX or FOLFIRI. By reducing the toxicity of
FOLFOXIRI, we believe trilaciclib will significantly expand use of FOLFOXIRI in patients living with CRC and potentially improve anti-tumor efficacy.

1L Metastatic Triple-Negative Breast Cancer (mTNBC)

Building upon the robust OS benefit observed in the prior Phase 2 study, we are enrolling patients in PRESERVE 2, a pivotal Phase 3 trial of trilaciclib in
patients receiving first-line gemcitabine and carboplatin for locally advanced unresectable or mTNBC. This study is evaluating trilaciclib in PD-L1 positive
and negative patients and largely replicates the design of the positive Phase 2 trial which demonstrated improved anti-tumor efficacy across patients. Anti-
tumor efficacy and myeloprotection endpoints are being assessed in this study. G1 has discontinued the 2L cohort of this trial given anticipated enrollment
concerns and limited commercial potential with the initial rapid uptake for Trodelvy® (sacituzumab govitecan-hziy) following its recent U.S. approval. G1
will broaden enrollment of the 1L cohort in this study to also include patients who received checkpoint inhibitors in the neo/adjuvant setting to ensure that
we develop clinical experience for trilaciclib in this increasingly relevant patient population.

1L Bladder Cancer

We are enrolling patients in PRESERVE 3, a randomized, open-label Phase 2 study of trilaciclib administered with first-line platinum-based chemotherapy
and  the  immune  checkpoint  inhibitor  avelumab  maintenance  therapy  in  patients  with  untreated,  locally  advanced  or  metastatic  urothelial  carcinoma
(“mUC”).  Myeloprotection  and  anti-tumor  efficacy  endpoints  are  being  assessed  in  this  study.  There  is  a  strong  rationale  to  evaluate  trilaciclib  in  1L
bladder  cancer:  (1)  bladder  is  a  known  immunogenic  tumor  proven  to  be  responsive  to  chemotherapy  and  immune  checkpoint  inhibitors;  (2)  the  most
common  chemotherapy  regimen  used  in  1L  bladder  cancer  is  gemcitabine  and  platinum,  which  is  similar  to  the  chemotherapy  regimen  in  our  mTNBC
study (gemcitabine and carboplatin) where we showed significant OS benefits; and (3) preclinical data suggests meaningful potential synergistic benefits
by combining trilaciclib with checkpoint inhibitors. We anticipate that the Phase 2 study will provide important data for trilaciclib in a known immunogenic
setting and is expected to help define future combination studies.

Phase 2 Study of Trilaciclib in Combination with an Antibody-Drug Conjugate (ADC)

Triple negative breast cancer (“TNBC”) is an area where trilaciclib, in our Phase 2 study, and ADCs – medicines that deliver targeted chemotherapy agents
to cancer cells – have both shown clinically meaningful and substantial improvements in overall survival. We believe that trilaciclib and ADCs could act
synergistically to improve patient outcomes with fewer myelosuppressive side effects. We are enrolling patients in a Phase 2 single arm study of trilaciclib
administered prior to the ADC Trodelvy® (sacituzumab govitecan-hziy) in patients with unresectable locally advanced or mTNBC who received at least
two prior treatments, at least one in the metastatic setting. We anticipate that data generated from this trial will be instructive in evaluating future ADC
combination possibilities.

Phase 2 Study to Confirm the Immune-Based Mechanism of Action (MOA) of Trilaciclib

We are enrolling patients in a Phase 2 study of trilaciclib and chemotherapy in patients with early-stage TNBC receiving neoadjuvant treatment, to evaluate
and confirm the immune-based mechanism of action (“MOA”) of trilaciclib. This trial in neoadjuvant TNBC replaced the I-SPY2 neoadjuvant breast trial
in G1’s pipeline given a treatment landscape shift in neoadjuvant TNBC from chemotherapy only to chemotherapy plus I/O (checkpoint inhibitors). This
MOA  study  will  build  upon  earlier  observations  from  the  Phase  2  TNBC  trial  and  preclinical  data  and  evaluate  the  potential  for  developing  rational
combinations  with  novel  targeted  therapies.  The  study  will  evaluate  immune  endpoints,  including  the  change  in  the  ratio  of  CD8+  tumor-infiltrating
lymphocytes (TILs) to regulatory T cells (Treg) in the tumor microenvironment following a single dose of trilaciclib, and impacts on immunomodulation.
We  anticipate  that  data  generated  from  the  MOA  study  will  inform  the  design  of  future  pivotal  studies  across  multiple  tumor  types  and  treatment
combinations.

Investigator Sponsored Studies (ISS) Program

The Company has a robust Investigator Sponsored Studies (“ISS”) program. An ISS is a study that is developed and conducted by a qualified physician
investigator  external  to  G1  who  assumes  full  responsibility  for  the  conduct  of  the  study.  An  ISS  can  take  a  variety  of  forms  including  clinical  and
nonclinical  studies  that  may  be  interventional  or  observational.  Our  ISS  program  supports  studies  that  align  with  our  areas  of  scientific  interest.  We
anticipate that the first ISS to be supported by G1 will be in 1L non-small cell lung cancer and expect it to be initiated in the second quarter of 2022.

Market opportunities for trilaciclib

Cancer is the second leading cause of death in the United States with an estimated 1.9 million new cases and 609,000 deaths projected to occur in 2022,
according to the American Cancer Society. Cytotoxic therapies (chemotherapies, antibody-drug conjugates, others) are the standard of care treatment for
multiple cancers.

Myelosuppression is a common serious adverse event related to cytotoxic therapies. These treatments have significant clinical utility and continue to be the
most  effective  treatment  for  many  cancers.  However,  cytotoxic  therapies  also  damage  HSPCs  (myelosuppression)  and  the  immune  system
(immunosuppression), leading to severe adverse effects and limiting anti-tumor activity. Myelosuppression causes abnormally low numbers of red blood
cells, or anemia, abnormally low numbers of neutrophils, or neutropenia, and/or abnormally low numbers of platelets, or thrombocytopenia. Treating or
preventing the myelosuppressive side effects of cytotoxic therapy presents a large market opportunity, with chemotherapy utilized in more than one million
patients in North America annually, and newer cytotoxic agents such as ADCs continuing to demonstrate benefits in expanding patient populations. The
only  current  treatments  for  chemotherapy-induced  myelosuppression  are  rescue  interventions  like  growth  factors  and/or  transfusions  given  after
myelosuppression  occurs.  COSELA  is  the  only  product  approved  to  proactively  prevent  chemotherapy-induced  myelosuppression  and  we  continue  to
evaluate the utility of trilaciclib to prevent myelosuppression in clinical trials with existing and newer cytotoxic therapies.

Additionally, significant unmet medical need continues to exist for products that can meaningfully improve the antitumor efficacy of existing and emerging
standard  of  care  therapies.  Despite  continued  advancements  of  new  treatment  modalities,  additional  novel  therapies  are  needed  to  further  improve  anti-
tumor efficacy, including in combination with newer agents. Trilaciclib is a novel compound with the potential to meaningfully improve anti-tumor efficacy
across  tumor  types  when  administered  in  treatment  combinations.  We  are  studying  trilaciclib  broadly  in  multiple  Phase  2  and  Phase  3  clinical  trials  to
evaluate its potential to improve anti-tumor efficacy and reduce adverse events commonly associated with cytotoxic therapies

Extensive-stage small cell lung cancer (ES-SCLC). According to the American Cancer Society, SCLC accounts for approximately 10-15% of
all  lung  cancers.  Approximately  30,000  people  are  treated  annually  in  the  United  States  for  ES-SCLC  across  first  line  through  third  line.
First-line treatment of ES-SCLC in the United States is typically a chemotherapy regimen of carboplatin and etoposide, which has significant
myelosuppressive  side  effects.  Combination  treatment  with  chemotherapy  and  immunotherapy  has  emerged  as  the  standard  of  care  in  the
United States. While these patients often respond to first-line therapy, approximately 90% progress within one year and die within two years.
Five-year survival rates are less than 5% for patients with ES-SCLC. Topotecan, approved for SCLC in 2007, is a standard treatment used in
the  second/third  line  setting  and  is  highly  myelosuppressive.  Based  on  market  research  we  have  completed  to  date,  many  physicians  see
proactive myeloprotection as a better approach for patients and would incorporate trilaciclib into their SCLC treatment regimen. We believe
the total market value of the trilaciclib opportunity for all eligible ES-SCLC patients in the U.S. exceeds $700 million.

Colorectal cancer (CRC). We are evaluating the use of trilaciclib in colorectal cancer in a Phase 3 trial that initiated in the fourth quarter of
2020  and  enrolled  the  first  patient  in  the  first  quarter  of  2021.  Colorectal  cancer  is  the  third  most  common  cancer  in  men  and  women,
excluding certain skin cancers. Globally, it is the second leading cause of cancer death, with more than 1.8 million people newly diagnosed
each year. In the United States, there are approximately 150,000 new cases diagnosed each year. Chemotherapy is the standard of care for
colorectal  cancer,  and  the  majority  of  patients  in  the  United  States,  Europe  and  Japan  receive  chemotherapy  as  part  of  their  treatment
regimen.

Breast  cancer.  We  are  evaluating  the  use  of  trilaciclib  in  a  variety  of  breast  cancers,  including  metastatic  triple  negative  breast  cancer
(mTNBC)  and  other  high-risk,  early-stage  breast  cancer  subtypes.  According  to  the  World  Health  Organization,  an  estimated  2.3  million
cases of breast cancer are diagnosed annually worldwide. Triple negative breast cancer makes up approximately 15-20% of such diagnosed
breast cancers. Because mTNBC cells lack key growth-signaling receptors, patients do not respond well to medications that block estrogen,
progesterone, or HER2 receptors. Instead, treating mTNBC typically involves chemotherapy, radiation, and surgery. In general, survival rates
tend to be lower with mTNBC compared to other forms of breast cancer, and mTNBC is also more likely to return after it has been treated,
especially in the first few years after treatment.

Bladder cancer. We are evaluating the use of trilaciclib in bladder cancer in a Phase 2 study that initiated in the second quarter of 2021. There
have  been  multiple  positive  registrational  studies  and  approvals  of  checkpoint  inhibitors  in  combination  with  chemotherapy,  and  these
combination regimens are emerging as a standard of care in multiple tumor types. Data from our trial of trilaciclib in combination with the
checkpoint inhibitor Tecentriq in patients with ES-SCLC showed myeloprotection benefits without impairing anti-tumor efficacy. This Phase
2 trial in bladder cancer will explore the use of trilaciclib in combination with chemotherapy for induction therapy and in combination with a
checkpoint inhibitor for maintenance therapy. We believe trilaciclib may improve outcomes for these patients based on potentially synergistic
benefits with both chemotherapy and immunotherapy. According to the American Cancer Society, there are over 81,000 new cases of bladder
cancer diagnosed in the United States  each  year,  and  over  17,000  reported  annual  deaths.  Globally,  there  are  nearly  575,000  new  bladder
cancer diagnoses each year.

Advantages of trilaciclib

Trilaciclib is a novel transient IV CDK4/6 inhibitor with unique attributes including rapid onset from IV administration, potent and selective CDK4 and
CDK6 inhibition and a short half-life. We believe that treating patients with trilaciclib prior to the administration of cytotoxic therapy or immunotherapy
regimens may have the following benefits and advantages:

•

•

•

•

•

•

•

•

Potential  to  decrease  the  incidence  of  chemotherapy-induced  myelosuppression.  Trilaciclib  has  been  rationally  designed  and  optimized  to
preserve HSPCs from damage by cytotoxic therapy, thereby minimizing cytopenias across neutrophils, red cells, and platelets. Trilaciclib has
the potential to decrease the clinically relevant consequences of these cytopenias and improve patient outcomes.

Potential to reduce cytotoxic therapy dose-delays and dose reductions. Chemotherapy-induced myelosuppression is the major dose limiting
toxicity of chemotherapy and can lead to dose reductions and schedule delays that can limit therapeutic benefit. Trilaciclib has been designed
specifically to minimize myelosuppression and has the potential to enable maintenance of the indicated and planned chemotherapeutic dose
and schedule.

Potential  to  improve  the  patient  experience  as  measured  by  validated  Patient  Reported  Outcomes  (PRO)  instruments.  PRO  data  from  our
randomized  trials  demonstrate  that  patients  receiving  trilaciclib  prior  to  chemotherapy  report  less  fatigue  and  improved  physical  and
functional well-being.

Potential for use with cytotoxic therapy / immune checkpoint inhibitors combinations. Immune checkpoint inhibitors are often combined with
cytotoxic  therapy.  We  have  demonstrated  that  trilaciclib  mitigates  myelosuppression  in  ES-SCLC  patients  treated  with  chemotherapy  in
combination with the immune checkpoint inhibitor Tecentriq. Additionally, our preclinical data suggests there may be meaningful potential
synergistic  benefits  in  terms  of  anti-tumor  efficacy  when  combining  trilaciclib  with  checkpoint  inhibitors  in  the  appropriate  treatment
settings.

Convenience of administration. Trilaciclib is designed to be administered via an IV infusion prior to chemotherapy treatment. This dosing
regimen fits with standard clinical practice for chemotherapy administration with or without checkpoint inhibitors.

Potential to reduce the cost of rescue interventions. Chemotherapy-induced myelosuppression leads to severe adverse side effects, such as
fatigue due to anemia, infections due to neutropenia, and bleeding due to thrombocytopenia. These adverse side effects often require costly
rescue interventions such as hospitalizations, transfusions, antibiotic usage and/or treatment with growth factor support. Because trilaciclib
has  been  designed  specifically  to  minimize  myelosuppression,  we  believe  that  it  has  the  potential  to  reduce  these  costs.  The  positive
multilineage myeloprotection data we have reported to date and our market research with payers supports the value proposition of trilaciclib
to reduce these costs.

Potential broad applicability.  We  believe  trilaciclib  has  the  potential  to  benefit  patients  treated  with  multiple  myelosuppressive  cytotoxic
regimens, including targeted chemotherapy (ADCs), across a wide range of tumor types.

Potential to improve anti-tumor efficacy and prolong overall survival in treatment combinations. Trilaciclib has demonstrated the ability to
improve anti-tumor efficacy and increase overall survival in our Phase 2 mTNBC study. Trilaciclib may increase patients’ ability to receive
more cytotoxic therapy, protect their immune systems from damage by cytotoxic therapy, and improve their immune responses by modulating
multiple immune functions while also allowing beneficial T cell proliferation. We are evaluating trilaciclib’s ability to improve anti-tumor
efficacy across multiple tumor types and in various treatment combinations in ongoing clinical studies.

Trilaciclib: preclinical and clinical development

Preclinical development

We  have  published  extensive  biochemical,  cellular  and  in  vivo  data  on  trilaciclib.    Our  preclinical  data  show  that  trilaciclib  can  induce  transient  and
reversible cell-cycle arrest of HSPCs; helps protect HSPCs from damage caused by chemotherapy; preserves bone marrow and immune system function;
improves  complete  blood  count  (CBC)  recovery;  helps  protect  from  bone  marrow  exhaustion;  prevents  myeloid  skewing  and  consequent  lymphopenia;
activates T-cells in the tumor microenvironment; and enhances chemotherapy and checkpoint inhibitor anti-tumor activity.

We are currently conducting extensive preclinical development work to assess the synergistic potential of trilaciclib with a variety of novel and emerging
therapeutic agents to identify synergies to evaluate in future clinical trials.

Completed Phase 1 clinical trial

In  2015,  we  completed  a  Phase  1  clinical  trial  of  trilaciclib  in  45  healthy  volunteers  in  the  Netherlands.  In  this  trial,  subjects  in  seven  cohorts  were
administered a single ascending dose of trilaciclib between 6 mg/m² and 192 mg/m². The purpose of this trial was to evaluate the safety including dose
limiting toxicities, or DLTs, serious adverse events, or SAEs, adverse events, or AEs, and pharmacokinetics, or PK, and identify a biologically effective
dose of trilaciclib. Published data from this trial demonstrated that trilaciclib was well tolerated, with no DLTs or SAEs reported. These data demonstrated
that the administration of trilaciclib resulted in the robust cell-cycle arrest of HSPCs for at least 32 hours and supported a starting dose of 200 mg/m 2 for
the initial studies in patients.

Phase 2 clinical program in SCLC (study 1 in package insert)

Based  on  the  encouraging  preliminary  data,  we  advanced  both  SCLC  trials  into  the  randomized,  placebo-controlled,  double-blind  Phase  2  segment.
Enrollment  in  the  first-line  SCLC  Phase  2  trial  was  completed  in  the  second  quarter  of  2017  and  positive  multilineage  myeloprotection  results  were
reported in March 2018, with additional data reported at the European Society for Medical Oncology (ESMO) 2018 Congress and published in Annals of
Oncology  (Weiss  et al.)  in  2019.  Enrollment  in  the  second/third-line  SCLC  Phase  2  trial  was  completed  in  the  second  quarter  of  2018,  with  positive
multilineage  myeloprotection  data  reported  in  the  fourth  quarter  of  2018  and  full  data  presented  at  an  oral  session  at  the  American  Society  of  Clinical
Oncology (ASCO) 2019 Annual Meeting. These data were also published in the International Journal of Cancer (Daniel et al.; 2020).

In December 2016, we entered into a non-exclusive agreement with Genentech to evaluate the combination of Genentech's immune checkpoint, anti-PD-L1
antibody  Tecentriq  with  trilaciclib.  Our  first  trial  under  the  agreement  is  in  first-line  treatment  for  patients  with  ES-SCLC  receiving  carboplatin  and
etoposide.  We  initiated  enrollment  in  this  randomized,  double-blinded,  placebo-controlled  Phase  2  trial  in  the  second  quarter  of  2017.  The  goals  of  the
clinical trial are to evaluate the safety, OS, myeloprotection, PK, and anti-tumor activity of trilaciclib in combination with Tecentriq and chemotherapy. We
completed enrollment in the first quarter of 2018. We reported positive multilineage myeloprotection data and preliminary progression free survival (PFS)
in November 2018, and presented updated safety and anti-tumor efficacy data at the 2019 ESMO Congress.

Phase 1b/2 clinical trial in first-line treatment of SCLC (study 2 in package insert)

In 2015, we initiated a Phase 1b/2 clinical trial in first-line ES-SCLC patients across multiple sites in the United States and Europe. The Phase 1b segment
of the trial was designed to confirm the trilaciclib dose to be used in the randomized, placebo-controlled Phase 2 segment. The goals of the trial are to
evaluate  the  safety,  myeloprotection,  pharmacokinetics,  and  anti-tumor  activity  of  trilaciclib  in  combination  with  the  existing  first-line  chemotherapy
standard  of  care  regimen  of  etoposide  and  carboplatin  and  to  confirm  the  dose  to  be  used  in  future  trials.  All  patients  in  the  Phase  1b  segment  were
administered  three-week  cycles  of  trilaciclib  plus  etoposide/carboplatin,  with  an  estimated  four  to  six  cycles  administered  in  total  per  patient  based  on
historical practice. Trilaciclib was administered as an IV infusion prior to every dose of etoposide/carboplatin.

In the Phase 1b section of this trial, as reported at the American Society of Clinical Oncology meeting in June 2017, we treated 19 patients with multiple
cycles of trilaciclib and chemotherapy and did not have a single episode of febrile neutropenia – one of the most common adverse consequences of these
chemotherapy  regimens.  We  also  observed  a  dose  dependent  reduction  in  grade  3/4  hematologic  adverse  events.    The  results  from  the  Phase  1b  study
support the hypothesis that trilaciclib could ameliorate the significant acute and long-term consequences of chemotherapy-induced myelosuppression by
preserving hematopoietic and immune system function. Based on these results, we initiated the randomized, placebo-controlled Phase 2 segment of the trial
in  fourth-quarter  of  2016  with  a  trilaciclib  dose  of  240  mg/m2  and  completed  enrollment  of  a  total  of  77  patients  in  the  second  quarter  of  2017.    We
reported positive multilineage myeloprotection data from the Phase 2 segment of the trial in March 2018, with additional data from the trial presented at the
2018 ESMO Congress and final data published in Annals of Oncology (Weiss et al.; 2019).

Phase 1b/2 clinical trial in second/third-line treatment of SCLC (study 3 in package insert)

In 2015, we initiated a Phase 1b/2 clinical trial in second/third-line SCLC patients across multiple sites in the United States and Europe. The Phase 1b
segment of the trial was designed to confirm the trilaciclib dose to be used in the randomized, placebo-controlled Phase 2 segment of the trial. The goals of
the  trial  are  to  evaluate  the  safety,  myeloprotection,  PK,  and  anti-tumor  activity  of  trilaciclib  in  combination  with  the  existing  second/third-line
chemotherapy  standard  of  care  regimen  of  topotecan  and  to  confirm  the  dose  to  be  used  in  future  trials.  All  patients  in  the  Phase  1b  segment  were
administered three-week cycles of trilaciclib plus topotecan until the progression of disease. Trilaciclib was administered as an IV infusion prior to every
dose of topotecan. Trilaciclib doses of 200 to 280 mg/m2 and topotecan doses of 0.75 to 1.5 mg/m2 were tested across 7 cohorts in the completed Phase 1b
open-label  segment  of  the  trial.  The  doses  chosen  for  the  randomized,  placebo-controlled  Phase  2  segment  of  this  trial  were  trilaciclib  240  mg/m2  +
topotecan 0.75 mg/m2 and trilaciclib 240 mg/m2 + topotecan 1.5 mg/m2.
In  the  Phase  1b  segment  we  treated  32  patients  with  trilaciclib  and  topotecan  without  any  episodes  of  febrile  neutropenia  or  treatment  related  SAEs.
Preliminary results from Phase 1b were reported at the IASCLC World Conference on Lung Cancer in December 2016. Based on these results, the Phase 2
segment was initiated in the first quarter of 2017 and consists of a double blind-design with 91 patients randomized on a 2:1 basis to receive trilaciclib plus
topotecan, or placebo plus topotecan. We completed enrollment in this trial in the second quarter of 2018 and reported multilineage myeloprotection data in
the fourth quarter of 2018. Safety and anti-tumor efficacy data were presented at the 2019 ASCO Annual Meeting. These data were published in the 2019
Advanced in Therapy (Hart et al.; 2020).

Our  double-blind  placebo  controlled  trials  of  trilaciclib  in  SCLC  trials  demonstrated  that,  when  added  to  standard  of  care  chemotherapy  or
chemotherapy/checkpoint inhibitor regimens, trilaciclib mitigates clinically significant chemotherapy-induced myelosuppression. The U.S. Food and Drug
Administration (“FDA”) granted Breakthrough Therapy Designation for trilaciclib based on myeloprotection data from our three randomized, double-blind,
placebo-controlled  SCLC  clinical  trials,  as  well  as  safety  data  collected  across  all  completed  and  ongoing  clinical  trials.  The  Breakthrough  Therapy
program is designed to expedite development and review of drugs intended for serious or life-threatening conditions. In August 2020, the FDA accepted
our  New  Drug  Application  (NDA)  for  trilaciclib  in  SCLC,  granting  Priority  Review  with  a  Prescription  Drug  User  Fee  Act  (PDUFA)  action  date  of
February  15,  2021.  COSELA™  (trilaciclib)  was  approved  by  the  FDA  on  February  12,  2021  to  decrease  the  incidence  of  chemotherapy-induced
myelosuppression  in  adult  patients  when  administered  prior  to  a  platinum/etoposide-containing  regimen  or  topotecan-containing  regimen  for  ES-SCLC.
Discussions with European regulatory authorities have indicated existing data is sufficient to support a Marketing Authorization Application (MAA) to the
European Medicines Agency (EMA) for trilaciclib for myeloprotection in SCLC, which we plan to pursue in collaboration with a partner.

Phase 2 clinical trial in metastatic Triple Negative Breast Cancer (mTNBC)

In January 2017, we initiated an open label, randomized, Phase 2 trial that enrolled 102 patients with first, second or third-line mTNBC across multiple
sites in the United States and Europe. The goals of the clinical trial are to evaluate the safety, myeloprotection, PK, and anti-tumor activity of trilaciclib in
combination with the existing chemotherapy standard of care regimen of gemcitabine and carboplatin (GC). We completed enrollment in the second quarter
of  2018.  At  the  December  2018  SABCS,  we  presented  preliminary  data  demonstrating  improvement  in  progression-free  survival  (PFS).  We  presented
additional safety and anti-tumor efficacy data at the 2019 ESMO Congress. The results of the trial demonstrated significant improvement in overall survival
(OS) (preliminary).  Though  the  trial  did  not  meet  the  primary  myeloprotection  endpoint,  patients  receiving  trilaciclib  were  able  to  receive  ~50%  more
cycles of chemo, without additional hematological toxicity. These data were presented at the 2019 ESMO

9

Congress and concurrently published in The Lancet Oncology (Tan et al.; 2019). Updated safety and efficacy data from this trial were presented at the 2020
SABCS. Data included that compared to GC alone (Group 1), OS was improved in both trilaciclib arms (Groups 2 and 3) (Group 2: HR=0.31, p=0.0016;
Group 3: HR=0.40, p=0.0004). Median OS was 12.6 months in Group 1, not reached for Group 2, and 17.8 months in Group 3. The median OS for Groups
2 and 3 combined was 19.8 months (HR=0.37, p<0.0001). OS findings in patients receiving trilaciclib were consistent with previously reported data from
this trial. The median OS for GC alone (Group 1, 12.6 months) was consistent with the previous trial findings and historical data. Patients with both PD-
L1-positive and PD-L1-negative tumors treated with trilaciclib and GC demonstrated improvement in OS compared to patients receiving GC alone, with
the PD-L1-positive subset achieving statistically significant improvement. Further, data from T cell clonality analyses suggest that administering trilaciclib
prior to chemotherapy enhanced immune system function.

Five ongoing clinical trials
Trilaciclib (IV CDK4/6 inhibitor)

Phase 3 clinical trial in first line Colorectal Cancer (PRESERVE 1)

We initiated PRESERVE 1 in first line colorectal cancer (CRC) in the fourth quarter of 2020, and in January of 2021 we enrolled the first patient. CRC is a
large  indication  commonly  treated  with  5-FU-based  chemotherapy.  We  have  extensive  preclinical  research  demonstrating  myeloprotection  and  potential
efficacy in 5-FU-based regimens with trilaciclib. The Phase 3 trial is being conducted across multiple sites in the United States and Europe. The study is
evaluating the safety, myeloprotection and antitumor efficacy of trilaciclib in combination with FOLFOXIRI, the most efficacious chemotherapy regimen
in CRC, but also highly myelosuppressive. The primary endpoint is myeloprotection; secondary endpoints include progression-free survival (PFS), overall
survival  (OS),  and  patient  reported  outcomes  (PRO).  We  expect  to  enroll  approximately  300  participants.  Initial  results  of  this  study  including
myeloprotection and Objective Response Rate (ORR) endpoints are expected in the first quarter of 2023.

Phase 3 clinical trial in first line Triple Negative Breast Cancer (PRESERVE 2)

Building upon the robust OS benefit observed in the prior Phase 2 study, in April 2021, we initiated PRESERVE 2, a pivotal Phase 3 trial of trilaciclib in
patients  receiving  first-  or  second-line  gemcitabine  and  carboplatin  chemotherapy  (“GC”)  for  locally  advanced  unresectable  or  mTNBC.  Anti-tumor
efficacy and myeloprotection endpoints are being assessed in this study. The Phase 3 trial is being conducted across multiple sites in the United States and
Europe. We made the strategic decision to discontinue the 2L arm of this trial due to a shift in the treatment paradigm for 2L mTNBC caused by the rapid
uptake of Trodelvy in this setting. This shift has created significant barriers to enrollment in the 2L cohort of this clinical study, and to the commercial
potential of trilaciclib in 2L mTNBC. Given this, we will enroll patients who previously received checkpoint inhibitors in the neo/adjuvant setting into the
1L arm of the trial, to ensure that we develop clinical experience in this patient population. We will continue to enroll and focus on 1L mTNBC patients, an
area of high unmet medical need. The primary endpoint is to evaluate the effect of trilaciclib on overall survival (OS) compared with placebo in patients
receiving  first-line  GC.  Key  secondary  endpoints  include  assessment  of  the  effect  of  trilaciclib  on  patients’  quality  of  life  compared  with  placebo.  We
expect to enroll approximately 170 1L patients. Initial results of this study including interim Overall Survival (OS) are expected in the second half of 2023.

Phase 2 clinical trial in first line Bladder Cancer (PRESERVE 3)

We  initiated  PRESERVE  3,  a  Phase  2,  randomized,  open-label  study  of  trilaciclib  administered  with  first-line  platinum-based  chemotherapy  and  the
immune checkpoint inhibitor avelumab maintenance therapy in patients with untreated, locally advanced or metastatic urothelial carcinoma (“mUC”), in
the second quarter of 2021. Myeloprotection and anti-tumor efficacy endpoints are being assessed in this study. The primary endpoint is to evaluate the
anti-tumor  efficacy  of  trilaciclib  when  combined  with  platinum-based  chemotherapy  and  the  checkpoint  inhibitor  avelumab  maintenance  therapy  as
measured by progression-free survival (PFS) during the overall study. Secondary endpoints include evaluation of the anti-tumor efficacy of trilaciclib  as
measured  by  the  objective  response  rate  (ORR),  duration  of  objective  response  (DOR),  PFS  in  the  maintenance  period,  overall  survival  (OS)  and
probability  of  survival  (POS)  at  Month  16,  and  evaluation  of  the  myeloprotective  effects  of  trilaciclib on chemotherapy-induced myelosuppression. We
have entered into a clinical trial collaboration with the alliance between Merck KGaA, Darmstadt, Germany and Pfizer whereby the alliance will contribute
clinical supply of avelumab to this G1-sponsored and funded trial in mUC. We expect to enroll approximately 90 patients. Initial results of this study for
ORR and myeloprotection are expected in the fourth quarter of 2022.

Phase 2 clinical trial in combination with the antibody-drug conjugate, Trodelvy® (Sacituzumab Govitecan-Hziy)

We initiated this Phase 2, single arm, open-label study of trilaciclib administered prior to the antibody-drug conjugate (ADC), Trodelvy® (sacituzumab
govitecan-hziy)  in  patients  with  unresectable  locally  advanced  or  mTNBC  in  the  fourth  quarter  of  2021.  ADCs  are  medicines  that  deliver  targeted
chemotherapy agents to cancer cells. Antitumor efficacy and myeloprotective endpoints are being assessed. The primary objective is to evaluate the anti-
tumor efficacy of trilaciclib when administered prior to sacituzumab govitecan-hziy as measured by progression-free survival (PFS). Secondary endpoints
include evaluation of the anti-tumor efficacy as

10

 
measured by the objective response rate (ORR), duration of objective response (DOR), clinical benefit rate (CBR), overall survival (OS); and evaluation of
the myeloprotective effects of trilaciclib. We expect to enroll approximately 45 patients. We anticipate that data generated from this trial will be instructive
in evaluating future ADC combination possibilities. Initial results of this study for ORR and myeloprotection are expected in the fourth quarter of 2022.

Phase 2 clinical trial to confirm the antitumor mechanism of action (MOA) in the tumor microenvironment

We initiated this trial in the fourth quarter of 2021. This trial in neoadjuvant triple negative breast cancer (“TNBC”) replaced the I-SPY2 neoadjuvant breast
trial in G1’s pipeline given a treatment landscape shift in neoadjuvant TNBC from chemotherapy only to chemotherapy plus I/O (checkpoint inhibitors).
The trial is a Phase 2, single arm, open-label study of trilaciclib in patients with early-stage neoadjuvant TNBC designed to further investigate the role of
trilaciclib  in  modulating  the  anti-tumor  immune  response.  Pathologic  complete  response  endpoints  are  also  being  evaluated  in  this  trial.  The  primary
objective is to evaluate the immune-based mechanism of action (“MOA”) of trilaciclib after a single-dose as measured by the change in the ratio of CD8+
tumor-infiltrating  lymphocytes  (TILs)  to  regulatory  T  cells  (Tregs)  in  the  tumor  microenvironment.  Secondary  and  exploratory  endpoints  include  the
assessment  of  pathologic  complete  response  (pCR)  at  the  time  of  definitive  surgery,  immune  response  and  profiling  measures.  We  anticipate  that  data
generated from this MOA study will inform design of future additional pivotal studies across multiple tumor types and treatment combinations. We expect
to enroll approximately 30 patients. Initial results of this study including results for immune endpoints (e.g., CD8+ / Treg ratio) are expected in the fourth
quarter of 2022.

Investigator Sponsored Studies (“ISS”) Program
Trilaciclib (IV CDK4/6 inhibitor)

An Investigator Sponsored Study (“ISS”) is a study that is developed and conducted by a qualified physician external to G1 Therapeutics who assumes full
responsibility  for  the  conduct  of  the  study.  An  ISS  can  take  a  variety  of  forms  including  clinical  and  nonclinical  studies  that  may  be  interventional  or
observational. We support studies that align with our areas of scientific interest.

We anticipate that the first ISS to be supported by G1 will be in 1L non small cell lung cancer. This ISS is expected to be initiated by the physician in the
second quarter of 2022.

Trilaciclib: regulatory status

COSELA for injection was approved by the FDA in February 2021 to decrease the incidence of chemotherapy-induced myelosuppression in adult patients
when  administered  prior  to  a  platinum/etoposide-containing  regimen  or  topotecan-containing  regimen  for  extensive-stage  small  cell  lung  cancer  (ES-
SCLC).  The  approval  was  based  on  three  small  cell  lung  cancer  (“SCLC”)  trials  demonstrating  that  trilaciclib,  when  added  to  standard  of  care
chemotherapy or chemotherapy/checkpoint inhibitor regimens, mitigates clinically significant chemotherapy-induced myelosuppression. Discussions with
European regulatory authorities have indicated existing data is sufficient to support an MAA to the EMA for trilaciclib for myeloprotection in ES-SCLC.

We received Breakthrough Therapy Designation from the FDA in 2019 based on positive myeloprotection data in small cell lung cancer patients from three
randomized  Phase  2  clinical  trials.  As  is  common  with  Breakthrough-designated  products  that  receive  priority  review,  we  will  conduct  certain  post-
marketing  activities,  including  in  vitro  drug-drug  interaction  and  metabolism  studies,  and  a  clinical  trial  to  assess  the  impact  of  trilaciclib  on  disease
progression  or  survival  in  patients  with  ES-SCLC  with  chemotherapy-induced  myelosuppression  treated  with  a  platinum/etoposide-containing  or
topotecan-containing regimen with at least a two year follow up. We intend to initiate the post-approval clinical trial in 2022.

In 2021, the FDA granted Fast Track designation to trilaciclib for use in combination with chemotherapy for the treatment of locally advanced or mTNBC.
Fast track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill unmet medical needs. The
purpose is to get important new drugs to the patient earlier. A drug that receives Fast Track designation may be eligible for more frequent engagements
with  the  FDA  to  discuss  a  drug’s  clinical  development  plan,  eligibility  for  Accelerated  Approval  and  Priority  Review,  and  Rolling  Review  in  which
completed sections of a New Drug Application (NDA) can be submitted for FDA review on a rolling basis rather than waiting until all sections of the NDA
are completed before the entire application can be reviewed.

We  continue  to  engage  in  research  and  clinical  development  of  trilaciclib  in  order  seek  regulatory  approval  to  market  additional  indications  in multiple
tumor types and treatment combinations, including colorectal cancer, breast cancer, bladder cancer.

Lerociclib

Lerociclib is a differentiated oral CDK4/6 inhibitor being developed for use in combination with other targeted therapies in multiple oncology indications.
In 2020, we entered into separate, exclusive agreements with EQRx, Inc. (rights for U.S., Europe, Japan and all markets outside Asia-Pacific) and Genor
Biopharma Co. Inc. (rights for Asia-Pacific, excluding Japan) for the development and commercialization of lerociclib in all indications. Combined, these
agreements provided $26.0 million in upfront payments, along with sales-based royalties and up to $330.0 million in potential milestone payments. EQRx,
Inc.  and  Genor  Biopharma  Co.  Inc.  are  responsible  for  all  costs  related  to  the  development  and  commercialization  of  lerociclib  in  their  respective
territories.

Rintodestrant

Rintodestrant is a clinical-stage oral SERD, for use as a monotherapy and in combination with CDK4/6 inhibitors, initially Ibrance® (palbociclib), for the
treatment of ER+, HER2- breast cancer. We are in the process of evaluating partnering options for rintodestrant.

CDK2 Inhibitor

In 2020, we entered into a global license agreement with ARC Therapeutics, LLC for the development and commercialization of an internally discovered
CDK2 inhibitor for all human and veterinary uses. ARC is currently granted an exclusive, royalty-bearing, license with the right to grant sublicenses to one
of our solely owned patent families.

Our Business Strategy

Our  goal  is  to  improve  the  lives  of  those  impacted  by  cancer  through  the  ongoing  development  and  expansion  of  trilaciclib.  Our  strategy  includes  the
following key components:

•

•

•

Establish COSELA (trilaciclib) as the standard of care for ES-SCLC in the United States. COSELA (trilaciclib) for Injection was approved
by the FDA in February 2021 to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior
to a platinum/etoposide-containing regimen or topotecan-containing regimen for extensive-stage small cell lung cancer (ES-SCLC).

Maximize  long-term  value  of  trilaciclib  by  executing  our  robust  tumor  agnostic  development  plan  across  multiple  indications  and
treatment settings. We believe that, because of its mechanism of action and unique attributes, including rapid onset from IV administration,
potent  and  selective  CDK4  and  CDK6  inhibition,  and  short  half  life  trilaciclib  has  the  potential  to  be  used  to  treat  patients  receiving
myelosuppressive cytotoxic therapies like chemotherapy and to meaningfully improve anti-tumor efficacy across multiple tumor types and
when administered in various treatment combinations.

Manage capital efficiently to fully fund operations. We intend to efficiently execute our capital management strategies to ensure our ability
to fund our operations, including the commercialization of COSELA in ES-SCLC, and our ongoing and future clinical programs to develop
trilaciclib in additional cancer indications.

Commercialization

In  February  2021,  the  U.S.  Food  and  Drug  Administration  (FDA)  approved  COSELA  (trilaciclib)  to  decrease  the  incidence  of  chemotherapy-induced
myelosuppression  in  adult  patients  when  administered  prior  to  a  platinum/etoposide-containing  regimen  or  topotecan-containing  regimen  for  extensive-
stage small cell lung cancer (ES-SCLC). In June 2020, we entered into a three-year co-promotion agreement for COSELA in the United States and Puerto
Rico  with  Boehringer  Ingelheim  Pharmaceuticals,  Inc.  (“BI”).  In  December  2021,  G1  and  BI  mutually  agreed  to  end  the  co-promotion  agreement  for
COSELA, effective March 2022. At that time, we announced that we would hire and deploy a total of 34 oncology sales representatives to accelerate sales
activities and help maximize the adoption of COSELA. As of February 21, 2022, all 34 sales representatives have been hired, trained and deployed. We are
now managing and executing all commercial activities in-house, including sales, marketing, market access and clinical nurse educator functions, as well as
product distribution. The G1 to One program serves as a patient hub and provides patient and healthcare provider services.

We  plan  to  globally  commercialize  our  product  candidates  through  the  establishment  of  collaboration  agreements  with  global  and/or  regional
pharmaceutical  companies  to  leverage  our  and  their  development  and  commercialization  infrastructures  and  capabilities,  enabling  us  to  cost-effectively
maximize the global commercial opportunities of our product candidates.

Manufacturing

We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We rely, and expect to continue to rely, on third parties
(contract  manufacturing  organizations,  or  CMOs)  for  the  manufacture  of  our  product  candidates.  To  date,  we  have  obtained  drug  substances  and  drug
products for our preclinical studies, clinical trials and commercial product from multiple third-party manufacturers. Redundant suppliers are in place for
some  of  our  drug  substances  and  drug  products.    As  development  proceeds  for  our  products,  we  will  evaluate  qualifying  additional  redundant
manufacturers for drug substances and drug products.

Although  we  are  reliant  on  third  parties  to  manufacture  our  products,  we  have  personnel  with  extensive  manufacturing  experience  to  oversee  the
relationships with our CMOs. CMOs are subject to extensive governmental regulations and we depend on them to manufacture our products in accordance
with  current  good  manufacturing  practices,  or  cGMP.  We  have  an  established  quality  assurance  program  to  ensure  that  the  CMOs  involved  in  the
manufacture  of  products  do  so  in  accordance  with  cGMP  and  other  applicable  U.S.  and  foreign  regulations.  We  believe  that  our  current  CMO  network
complies with such regulations.

Competition

The development and commercialization of new drug therapies is highly competitive. We will face competition with respect to all therapeutics we may
develop or commercialize in the future from pharmaceutical and biotechnology companies worldwide. Any drug candidates we successfully develop and
commercialize will compete with currently marketed drugs and therapies used for treatment of the same indications, and potentially with products currently
in development for the same indications. Many of the entities marketing or developing potentially competing products have significantly greater financial
resources  and  expertise  than  we  do  in  research  and  development,  manufacturing,  preclinical  testing,  conducting  clinical  trials,  obtaining  regulatory
approvals and marketing. We believe the key competitive factors affecting the success of any approved product will be its efficacy, safety profile, price,
convenience of administration, and level of promotional activity. Accordingly, our commercial opportunity will be reduced or eliminated if our competitors
develop and commercialize products that are more effective, have fewer side effects, are more convenient or are less expensive than any products that we
may develop.

COSELA is the first approved therapy designed and optimized to help protect HSPCs and immune system function from damage by chemotherapy. We
believe administering trilaciclib with the current standard of care may minimize chemotherapy-induced myelosuppression, including the following adverse
side effects: fatigue due to anemia; infections due to neutropenia; and bleeding due to thrombocytopenia. Currently, these adverse side effects often require
costly rescue interventions such as hospitalizations, transfusions, antibiotic usage and/or treatment with growth factor support. Trilaciclib may reduce the
need to administer the existing rescue growth factor support treatments, including Neulasta® (pegfigrastim), Neupogen® (filgrastim), Procrit® (epoeitin
alpha),  and  Aranesp®  (darbepoetin  alfa)  as  well  as  biosimilars  of  these  products.  In  addition,  trilaciclib  may  compete  with  multiple  approved  drugs  or
drugs that may be approved in the future, such as plinabulin which is in development for chemotherapy induced-neutropenia and ALRN-6924 which is in
development for chemotherapy-induced myelosuppression.

Intellectual property

Our commercial success depends in part on our ability to obtain and maintain proprietary protection in jurisdictions where we seek to commercialize our
FDA approved CDK4/6 inhibitor trilaciclib (COSELA).  Our commercial success also depends in part on our ability to obtain and maintain proprietary
protection  in  the  jurisdictions  where  our  licensees  seek  to  commercialize  our  proprietary  CDK  inhibitors,  including  clinical  candidates  trilaciclib  and
lerociclib. We have secured patent protection to the composition of matter for trilaciclib and lerociclib in a number of jurisdictions, including for example,
the United States, Europe, China, Hong Kong, Macau, Japan, Korea, Singapore, Australia, Canada, Mexico, India, Israel, Russia, and Brazil.  We have
secured  patent  protection  to  the  use  of  trilaciclib  or  lerociclib  for  the  treatment  of  certain  cancers,  including  in  the  United  States,  Europe,  China,  Hong
Kong, Macau, and Japan.  We have secured patent protection to the composition of matter for rintodestrant in the Unites States, Japan, Australia, Mexico,
Russia,  and  the  Eurasian  Patent  Organization  (EAPO).  We  also,  where  we  believe  appropriate,  seek  protection  on  processes  for  the  production  of  our
CDK4/6  inhibitors  and  in-licensed  SERD  compound,  formulations,  additional  compositions,  combinations  of  our  product  candidates  with  other  active
agents and dosing schedules and regimens. Our success also depends on our ability to operate without infringing on the proprietary rights of others and to
prevent others from infringing our proprietary rights. Our policy is to seek to protect our proprietary position by, among other methods, filing U.S. and
foreign patent applications covering our proprietary technology, inventions, and improvements that are important to the development and implementation
of our business. In addition, we plan to seek patent term adjustments, restorations, and/or patent term extensions where applicable in the United States and
other jurisdictions. We also rely on trade secrets, know-how, continuing technological innovation and potential in-licensing opportunities to develop and
maintain our proprietary position. Additionally, we expect to benefit, where appropriate, from statutory frameworks in the United States, Europe, and other
countries that provide a period of clinical data exclusivity to compensate for the time required for regulatory approval of our drug products. See also the
“Government Regulation and Product Approval” section below.

We are the sole owner or exclusive licensee of all of our patents and currently filed patent applications that cover trilaciclib, lerociclib, and rintodestrant.
We have the exclusive right to prosecute these patent families in our sole discretion, and, where we have out-licensed patents and patent applications, our
licensees have the right to review and comment on all material patent filings, and their

13

 
 
 
 
review and comments will be considered by us in good faith. Our intellectual property strategy includes patenting our CDK4/6 inhibitors, their uses, and
methods  of  manufacturing  as  well  as  our  in-licensed  applications  directed  to  selective  estrogen  receptor  degraders  and  their  uses,  manufacture,  and
combination with our and other CDK4/6 inhibitors. We have obtained more than twenty composition-of-matter patents in the United States on a number of
our CDK4/6 inhibitors, including claims that cover trilaciclib and lerociclib, and we continue to seek composition-of-matter patents on additional CDK
inhibitors both in the United States and throughout the world. In addition, we have obtained more than twelve patents in the United States on methods of
treatment using a number of our CDK4/6 inhibitors, including claims that cover methods of using trilaciclib and lerociclib. We continue to seek additional
patents for our key CDK4/6 inhibitors and their uses in key therapeutic areas.

As of December 31, 2021, we have listed 10 U.S. granted patents in the U.S. FDA’s Orange Book for our U.S. Food and Drug Administration approved
drug trilaciclib (COSELA).  In addition, on April 8, 2021, we filed a request for patent term extension pursuant to 35 U.S.C. § 156 on two of these listed
patents (U.S. 8,598,186 and U.S. 9,487,530).  We ultimately intend to elect one patent for extension.  To the extent U.S. 8,598,186 is elected, the term is
expected to be extended to December 30, 2034.  To the extent U.S. 9,487,530 is elected, the term is expected to be extended to February 12, 2035.

We have also obtained two composition-of-matter patents, and two method of treatment patents, in the United States on the SERD compounds that we have
exclusively in-licensed, including rintodestrant. We also seek patent protection on methods of treatment that incorporate in-licensed SERD compounds in
combination with other therapeutic agents to treat specific clinical indications and targeted patient populations.

We  continually  assess  and  refine  our  intellectual  property  strategies  as  we  develop  new  technologies  and  product  candidates.  We  plan  to  file  additional
patent applications based on our intellectual property strategies where appropriate, including where we seek to adapt to competition or to improve business
opportunities. Further, we plan to file patent applications, as we consider appropriate under the circumstances, to protect new technologies that we develop.
Our  patent  filing  strategy  typically  includes  seeking  patent  protection  in  the  United  States,  the  European  Union,  and  in  additional  countries  where  we
believe such protection is likely to be useful, including one or more of Australia, Brazil, Canada, China, Hong Kong, India, Israel, Japan, Mexico, Macau,
Russia, Singapore, and South Korea.

We  are  party  to  four  license  agreements  relating  to  our  CDK  inhibitor  technology.  On  May  22,  2020,  we  entered  into  a  license  agreement  with  ARC
Therapeutics, LLC, (“ARC”) where we out-licensed to ARC a portfolio of CDK2 inhibitors for development and commercialization. On June 15, 2020, we
entered into a license agreement with Genor Biopharma Co. Inc.(“Genor”) for the development and commercialization of our CDK4/6 inhibitor lerociclib
in the Genor Territory. On July 22, 2020, we entered into a license agreement with EQRx, Inc. (“EQRx”) for the development and commercialization of
lerociclib  in  the  EQRx  Territory.  On  August  3,  2020,  we  entered  into  a  license  agreement  with  Nanjing  Simcere  Dongyuan  Pharmaceutical  Co.,  Ltd,
(“Simcere”) for the development and commercialization of our CDK4/6 inhibitor trilaciclib in the Simcere Territory. Each of these license agreements is
described below.

Our owned and in-licensed patent estate as of December 31, 2021, on a worldwide basis, includes over 375 granted or pending patent applications in more
than 30 patent families with more than 40 granted U.S. patents. The term of individual patents depends upon the laws of the countries in which they are
obtained. In the countries in which we currently file, the patent term is 20 years from the earliest date of filing of a non-provisional patent application which
serves as a priority application. However, the term of a U.S. patent may be extended to compensate for the time required to obtain regulatory approval to
sell a drug (a patent term extension) or by delays encountered during patent prosecution that are caused by the United States Patent and Trademark Office
(USPTO) (referred to as patent term adjustment). For example, the Hatch-Waxman Act permits a patent term extension for FDA-approved drugs of up to
five years beyond the expiration of the patent. The length of the patent term extension is related to the length of time the drug is under regulatory review
and diligence during the review process. Patent term extensions cannot extend the remaining term of a patent beyond a total of 14 years from the date of
product approval, and only one patent covering an approved drug or its method of use may be extended. A similar kind of patent extension, referred to as a
Supplementary  Protection  Certificate,  is  available  in  Europe.  Legal  frameworks  are  also  available  in  certain  other  jurisdictions  to  extend  the  term  of  a
patent.  We  currently  intend  to  seek  patent  term  extensions  on  any  of  our  issued  patents  in  any  jurisdiction  where  we  have  a  qualifying  patent  and  the
extension is available; however, there is no guarantee that the applicable regulatory authorities, including the FDA and the USPTO in the United States,
will agree with our assessment of whether such extensions should be granted, and even if granted, the length of such extensions. Further, even if our patent
is extended, the patent, including the extended portion of the patent, may be held invalid or unenforceable by a court of final jurisdiction in the United
States or a foreign country.

Our current issued patents covering the composition-of-matter for trilaciclib and lerociclib will expire in 2031, exclusive of any patent term extension. As
described  above,  we  have  filed  a  request  for  patent  term  extension  under  35  U.S.C.  §  156  for  a  term  extension  of  U.S.  8,598,186,  which  claims  the
composition  of  matter  of  trilaciclib,  which,  if  granted,  would  extend  the  term  of  this  patent  to  December  30,  2034.  Our  current  issued  patents  covering
methods of use of trilaciclib and lerociclib will expire in 2034 to 2035. As described above, we have filed a request for patent term extension under 35
U.S.C. § 156 for a term extension of U.S. 9,487,530,

14

which claims the use of trilaciclib to reduce the effect of chemotherapy on healthy cells in a subject being treated for, among other things, small cell lung
cancer, which, if granted, would extend the term of this patent to February 12, 2035. Our pending applications on additional methods of use of trilaciclib
and lerociclib, should they issue, will expire on dates ranging from 2034 to 2042. We plan to file additional applications on aspects of our innovations that
may have patent terms that extend beyond these dates.

Our  in-licensed  patent  covering  the  composition-of-matter  of  our  clinical  candidate  rintodestrant  will  expire  in  2036,  exclusive  of  any  patent  term
extension. Our pending applications on additional methods and combinations relating to rintodestrant, should they issue, will expire in 2038.

Any of our patents, including patents that we may rely on to protect our market for approved drugs, may be held invalid or unenforceable by a court of final
jurisdiction.  Alternatively,  we  may  decide  that  it  is  in  our  interest  to  settle  a  litigation  in  a  manner  that  affects  the  term  or  enforceability  of  our  patent.
Changes  in  either  the  patent  laws  or  in  interpretations  of  patent  laws  in  the  United  States  and  other  countries  may  diminish  our  ability  to  protect  our
inventions and enforce our intellectual property rights. Accordingly, we cannot predict the breadth or enforceability of claims that have been or may be
granted in our patents or in third-party patents. The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents
and  other  intellectual  property  rights.  Our  ability  to  obtain  and  maintain  our  proprietary  position  for  our  CDK4/6  inhibitors  or  our  in-licensed  SERD
compound will depend on our success in enforcing the claims that have been granted or may grant. We do not know whether any of the pending patent
applications that we have filed or may file or license from third parties will result in the issuance of any additional patents. The issued patents that we own
or may receive in the future may be challenged, invalidated, or circumvented, and the rights granted under any issued patents may not provide us with
sufficient protection or competitive advantages against competitors with similar technology. Furthermore, our competitors may be able to independently
develop and commercialize drugs with similar mechanisms of action and duplicate our methods of treatments or strategies without infringing our patents.
Because of the extensive time required for clinical development and regulatory review of a drug we may develop, it is possible that, before any of our drugs
can  be  commercialized,  any  related  patent  may  expire  or  remain  in  force  for  only  a  short  period  following  commercialization,  thereby  reducing  any
advantage of any such patent.

Trilaciclib and lerociclib patent coverage

We  own  seven  issued  U.S.  Patents  (U.S.  8,598,186;  U.S.  8,598,197;  U.S.  9,957,276;  U.S.  10,189,849;  U.S.  10,189,850;  U.S.  10,927,120;  and  U.S.

Rintodestrant Patent Coverage

We have exclusively licensed from University of Illinois, or the University, two patent families that cover rintodestrant and related compounds and their
pharmaceutical  compositions  and  use  as  selective  estrogen  receptor  down-regulators.  Selected  applications  from  these  families  are  pending  in  ARIPO,
Australia, Brazil, Canada, China, Eurasia, Europe, Israel, India, Japan, Korea, Mexico, New Zealand, Russia, United States, and South Africa. Four U.S.
Patents (U.S. 10,118,910, U.S. 10,377,735, 10,807,964, and 11,072,595) have issued from this family. We have also received issued patents in Australia,
Eurasia, Japan, Russia, Mexico and South Africa. The expected year of expiration for these patent families, where issued, valid and enforceable, is 2036,
without regard to any extensions, adjustments, or restorations of term that may be available under national law. Under the Exclusive License Agreement
with the University, we have the right to prosecute the licensed applications, subject to review by the University.

We co-own, along with the University, patent applications filed in the United States, Europe, Australia, Brazil, Canada, China, Israel, India, Japan, South
Korea, Mexico, Russia, New Zealand, and the regional patent offices of ARIPO and the EAPO directed to the combination of rintodestrant and related
compounds  with  lerociclib  and  related  compounds  for  the  treatment  of  estrogen-modulated  disorders  such  as  RB-positive  breast  cancer.  We  have
exclusively licensed the University’s rights in this co-owned application. The expected year of expiration for this patent family, where issued, valid and
enforceable, is 2038, without regard to any extensions, adjustments, or restorations of term that may be available under national law.

A  number  of  our  pending  patent  applications  covering  certain  aspects  of  using  trilaciclib,  lerociclib,  or  rintodestrant  have  not  yet  issued.  As  with  other
biotechnology and pharmaceutical companies, our ability to obtain and maintain a proprietary position on our drug candidates and technologies will depend
on  our  success  in  obtaining  effective  patent  claims  on  these  pending  patents  and  enforcing  those  claims  if  granted.  However,  our  pending  patent
applications,  and  any  patent  applications  that  we  may  in  the  future  file  or  license  from  third  parties,  may  not  result  in  the  issuance  of  patents.  We  also
cannot predict the breadth of claims that may be allowed or enforced in our patents.

Any issued patents that we have received or may receive in the future may be challenged, invalidated or circumvented. In addition, because of the extensive
time required for clinical development and regulatory review of a drug candidate we may develop, it is possible that, before any of our drug candidates can
be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby limiting protection such
patent would afford the respective product and any competitive advantage such patent may provide. Moreover, even our issued patents do not guarantee us
the right to practice our technology in relation to the commercialization of our clinical candidates. The area of patent and other intellectual property rights
in pharmaceuticals is an evolving one with many risks and uncertainties, and third parties may have blocking patents that could be used to prevent us from
commercializing our clinical candidates.

Exclusive license for rintodestrant

In  November  2016,  we  entered  into  a  license  agreement  with  the  University  of  Illinois,  the  University,  pursuant  to  which  we  obtained  an  exclusive,
worldwide  license  to  make,  use,  import,  sell  and  offer  for  sale  certain  SERDs,  including  rintodestrant,  covered  by  patent  rights  owned  by  the
University. The rights licensed to us are for all fields of use. The November 2016 license agreement was amended in March 2017.

Under  the  terms  of  the  agreement  we  paid  a  one-time  only,  non-refundable  upfront  fee  of  $0.5  million,  and  we  are  required  to  pay  the  University  low
single-digit royalties on all net sales of products and a share of any sublicensing revenues. We are also obligated to pay annual maintenance fees, which are
fully  creditable  against  any  royalty  payments  made  by  us.  We  will  also  be  required  to  pay  the  University  milestone  payments  of  up  to  an  aggregate  of
$2.6 million related to the initiation and execution of clinical trials and first commercial sale of a product in multiple countries. Under the terms of the
agreement, we control prosecution, and are required to consider the input of the University with regard to certain patent filings. We are also responsible for
any future patent prosecution costs that may arise.

The term of the license agreement will continue on a country-by-country basis until the later of (i) the expiration of the last valid claim within the patent
rights covering the product in such country, (ii) the expiration of market exclusivity in such country and (iii) the 10th anniversary of the first commercial
sale in such country. The University may terminate the agreement in the event (i) we fail to pay any amount or make any report when required to be made
and fail to cure such failure within 30 days after receipt of notice, (ii) we are in breach of any provision of the agreement and fail to remedy such breach
within 45 days after receipt of notice, (iii) we make a report to the University under the agreement that is determined to be materially false, (iv) we declare
insolvency or bankruptcy or (v) we take any action that causes patent rights or technical information to be subject to any lien or encumbrance and fail to
remedy  within  45  days  of  receipt  of  notice.  We  may  terminate  the  agreement  at  any  time  upon  at  least  90  days’  written  notice.  Upon  expiration  or
termination of the agreement, all rights revert to the University.

Trade secrets

In  addition  to  patents,  we  rely  upon  unpatented  trade  secrets  and  know-how  and  continuing  technological  innovation  to  develop  and  maintain  our
competitive position. We seek to protect our proprietary information, in part, using confidentiality agreements with our commercial partners, collaborators,
employees,  and  consultants,  and  invention  assignment  agreements  with  our  employees.  These  agreements  are  designed  to  protect  our  proprietary
information and, in the case of the invention assignment agreements, to grant us ownership of technologies that are developed through a relationship with a
third  party.  These  agreements  may  be  breached,  and  we  may  not  have  adequate  remedies  for  any  breach.  In  addition,  our  trade  secrets  may  otherwise
become known or be independently discovered by competitors. To the extent that our commercial partners, collaborators, employees, and consultants use
intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Government regulation and product approval

FDA approval process

In the United States, pharmaceutical products are subject to extensive regulation by the U.S. Food and Drug Administration, or FDA. The Federal Food,
Drug,  and  Cosmetic  Act,  or  the  FDC  Act,  and  other  federal  and  state  statutes  and  regulations,  govern,  among  other  things,  the  research,  development,
testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling,
and  import  and  export  of  pharmaceutical  products.  Failure  to  comply  with  applicable  U.S.  requirements  may  subject  a  company  to  a  variety  of
administrative or judicial sanctions, such as FDA refusal to approve pending new drug applications, or NDAs, warning letters, voluntary product recalls,
product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties, and criminal prosecution.

Preclinical tests include laboratory evaluation of product chemistry, formulation, and toxicity, as well as animal studies to assess the pharmacokinetic and
pharmacodynamic  characteristics  and  potential  safety  and  effectiveness  of  the  product.  The  conduct  of  the  preclinical  tests  must  comply  with  certain
federal regulations and requirements, including good laboratory practices, or GLP, for any safety testing. The results of preclinical testing are submitted to
the  FDA  as  part  of  an  IND  along  with  other  information,  including  information  about  product  chemistry,  manufacturing  and  controls,  and  a  proposed
clinical  trial  protocol.  Long-term  nonclinical  tests,  such  as  animal  tests  of  reproductive  toxicity  and  carcinogenicity,  may  continue  after  the  IND  is
submitted.

19

 
Clinical trials involve the administration of the investigational new drug to healthy volunteers or patients under the supervision of qualified investigators.
Clinical trials must be conducted: (i) under the supervision of one or more qualified investigators and in compliance with federal regulations, including
those encompassing good clinical practice, or GCP, requirements that are meant to protect the rights and welfare of study subjects and to define the roles of
clinical  trial  sponsors,  investigators,  and  monitors,  and  (ii)  under  protocols  detailing  the  objectives  of  the  clinical  trial,  the  parameters  to  be  used  in
monitoring safety and the effectiveness criteria to be evaluated.

The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time by imposing a clinical hold or impose other sanctions if it
believes  that  the  clinical  trial  either  is  not  being  conducted  in  accordance  with  FDA  requirements  or  presents  an  unacceptable  risk  to  the  clinical  trial
subjects. The clinical trial protocol and informed consent information for subjects in clinical trials must also be submitted for review and approval by an
institutional review board, or IRB, on behalf of each participating in the clinical trial before the trial commences at that site. An IRB also monitors the trial
until  completion  and  may  require  the  clinical  trial  at  the  site  to  be  halted,  either  temporarily  or  permanently,  for  failure  to  comply  with  the  IRB’s
requirements or for safety issues or it may impose other conditions on the clinical investigators or the sponsor of the clinical trial.

After completion of the required clinical testing, an NDA is prepared and submitted to the FDA. FDA approval of the NDA is required before marketing of
the  product  may  begin  in  the  United  States.  The  NDA  must  include  the  results  of  all  nonclinical,  clinical,  and  other  testing  and  a  compilation  of  data
relating  to  the  product’s  chemistry,  manufacture,  and  controls.  The  cost  of  preparing  and  submitting  an  NDA  is  substantial.  Under  federal  law,  the
submission of most NDAs is additionally subject to a substantial application user fee, currently over $2.8 million for an NDA with clinical information, and
the  manufacturer  and/or  sponsor  under  an  approved  NDA  is  also  subject  to  an  annual  program  fee,  currently  over  $330,000.  These  fees  are  typically
increased annually. Fee waivers or reductions are available in certain circumstances.

The  FDA  has  60  days  from  its  receipt  of  an  NDA  to  determine  whether  the  application  will  be  accepted  for  filing  based  on  the  agency’s  threshold
determination that it is sufficiently complete to permit substantive review. Once the submission is accepted for filing, the FDA begins an in-depth review.
The FDA has agreed to certain performance goals in the review of NDAs. The FDA seeks to review applications for standard review drug products within
ten months, and applications for priority review drugs within six months. Priority review can be applied to drugs intended to treat a serious condition and
that the FDA determines offer major advances in treatment, or provide a treatment where no adequate therapy exists. The review process for both standard
and priority reviews may be extended by FDA for three additional months to consider additional, late-submitted information, or information intended to
clarify information already provided in the submission in response to FDA review questions.

The FDA may also refer applications for novel drug products, or drug products that present difficult questions of safety or efficacy, to an external advisory
committee, which is typically a panel that includes clinicians and other experts, for review, evaluation, and a recommendation as to whether the application
should  be  approved.  The  FDA  is  not  bound  by  the  recommendation  of  an  advisory  committee,  but  it  generally  follows  such  recommendations.  Before
approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. Additionally, the FDA will typically inspect
the facility or the facilities at which the drug is manufactured, unless the facility has recently had an FDA inspection. The FDA also typically inspects the
application  sponsor.  The  FDA  will  not  approve  the  product  unless  compliance  with  current  good  manufacturing  practice,  or  cGMP,  requirements  is
satisfactory and the NDA contains data that provide substantial evidence that the drug is safe and effective in the indication studied.

After the FDA evaluates the NDA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response
letter  generally  outlines  the  deficiencies  in  the  submission  and  may  require  substantial  additional  testing,  or  additional  nonclinical  or  clinical  study
information,  in  order  for  the  FDA  to  reconsider  the  application.  If  a  complete  response  letter  is  issued,  the  applicant  may  either  resubmit  the  NDA,
addressing  all  of  the  deficiencies  identified  in  the  letter,  or  withdraw  the  application.  If,  or  when,  those  deficiencies  have  been  addressed  to  the  FDA’s
satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or six
months depending on the type of information included.

An approval letter authorizes commercial marketing of the drug with the accompanying approved prescribing information for specific indications. As a
condition of NDA approval, the FDA may require a risk evaluation and mitigation strategy, or REMS, in addition to the approved labeling, to help ensure
that the benefits of the drug outweigh its risks. A REMS could include communication plans for health care professionals, medication guides for patients,
and/or elements to assure safe use, or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing,
restricted distribution requirements, dispensing only under certain circumstances, special monitoring, and the use of patient registries. The FDA determines
the requirement for a REMS, as well as the specific REMS provisions, on a case-by-case basis. If the FDA concludes a REMS plan is needed, the sponsor
of the NDA must submit a proposed REMS plan. The requirement for a REMS can materially affect the potential market and profitability of the drug.
Moreover,  product  approval  may  require  substantial  post-approval  testing  and  surveillance  to  monitor  the  drug’s  safety  or  efficacy  as  described  as
postmarketing commitments or requirements included in the approval letter. Once granted, product approvals may be

20

withdrawn if compliance with regulatory requirements and commitments is not maintained or problems are identified following initial marketing.

Disclosure of clinical trial information

Sponsors  of  clinical  trials  of  certain  FDA-regulated  products,  including  prescription  drugs,  are  required  to  register  and  disclose  certain  clinical  trial
information on a public registry maintained by the U.S. National Institutes of Health (NIH). Information related to the product, patient population, phase of
investigation, clinical trial sites and investigator, and other aspects of the clinical trial is made public as part of the registration of the clinical trial. Although
sponsors are also obligated to disclose the results of their clinical trials after completion, disclosure of the results may be delayed in some cases for up to
two years after the date of completion of the trial. Competitors may use this publicly-available information to gain knowledge regarding the design and
progress of our development programs. Failure to timely register a covered clinical study or to submit study results as provided for in the law can give rise
to civil monetary penalties and also prevent the non-compliant party from receiving future grant funds from the federal government. The NIH’s Final Rule
on ClinicalTrials.gov registration and reporting requirements became effective in 2017, and both NIH and FDA have signaled the government’s willingness
to begin enforcing those requirements against non-compliant clinical trial sponsors.

Data privacy and the protection of personal information

We are subject to laws and regulations governing data privacy and the protection of personal information including health information. The legislative and
regulatory  landscape  for  privacy  and  data  protection  continues  to  evolve,  and  there  has  been  an  increasing  focus  on  privacy  and  data  protection  issues
which  will  continue  to  affect  our  business.    In  the  United  States,  we  may  be  subject  to  state  security  breach  notification  laws,  state  laws  protecting  the
privacy of health and personal information and federal and state consumer protections laws which regulate the collection, use, disclosure and transmission
of  personal  information.  These  laws  overlap  and  often  conflict  and  each  of  these  laws  is  subject  to  varying  interpretations  by  courts  and  government
agencies,  creating  complex  compliance  issues  for  us.    If  we  fail  to  comply  with  applicable  laws  and  regulations  we  could  be  subject  to  penalties  or
sanctions,  including  criminal  penalties.    Our  customers  and  research  partners  must  comply  with  laws  governing  the  privacy  and  security  of  health
information, including the Health Insurance Portability and Accountability Act of 1996 as amended (“HIPAA”) and state health information privacy laws.
If we knowingly obtain health information that is protected under HIPAA, called “protected health information”, our customers or research collaborators
may be subject to enforcement and we may have direct liability for the unlawful receipt of protected health information or for aiding and abetting a HIPAA
violation.  

State  laws  protecting  health  and  personal  information  are  becoming  increasingly  stringent.    For  example,    California  has  implemented  the  California
Confidentiality  of  Medical  Information  Act  that  imposes  restrictive  requirements  regulating  the  use  and  disclosure  of  health  information  and  other
personally identifiable information, and California has recently adopted the California Consumer Privacy Act of 2018 (the CCPA).  The CCPA mirrors a
number of the key provisions of the EU General Data Protection Regulation (GDPR) described below.  The CCPA establishes a new privacy framework for
covered  businesses  by  creating  an  expanded  definition  of  personal  information,  establishing  new  data  privacy  rights  for  consumers  in  the  State  of
California, imposing special rules on the collection of consumer data from minors, and creating a new and potentially severe statutory damages framework
for violations of the CCPA and for businesses that fail to implement reasonable security procedures and practices to prevent data breaches.  Additionally, a
new  privacy  law,  the  California  Privacy  Rights  Act  (CPRA),  was  approved  by  California  voters  in  the  election  on  November  3,  2020,  and  certain
provisions  are  effective  as  of  January  1,  2022,  with  full  effectiveness  as  of  January  1,  2023.  The  CPRA  modifies  the  CCPA  significantly,  potentially
resulting in further uncertainty, additional costs and expenses in an effort to comply and additional potential for harm and liability for failure to comply.
Among other things the CPRA established a new regulatory authority, the California Privacy Protection Agency, with will be enacting new regulations and
will have expanded enforcement authority.  Virginia and Colorado enacted similar data protection laws in 2021, and other U.S. states have proposals under
consideration, increasing the regulatory compliance risk.  

The Hatch-Waxman Act and marketing applications for follow-on drugs

In 1984, with passage of the Hatch-Waxman Amendments to the FDC Act, Congress authorized the FDA to approve generic drugs that are the same as
drugs previously approved by the FDA under the NDA provisions of the statute and also enacted Section 505(b)(2) of the FDC Act. To obtain approval of a
generic  drug,  an  applicant  must  submit  an  abbreviated  new  drug  application,  or  ANDA,  to  the  agency.  In  support  of  such  applications,  a  generic
manufacturer may rely on the preclinical and clinical testing conducted for a drug product previously approved under an NDA, known as the reference
listed drug, or RLD. Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to
the active ingredients, the route of administration, the dosage form, and the strength of the drug. At the same time, the FDA must also determine that the
generic drug is “bioequivalent” to the innovator drug.

21

Orange book listing

In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent that has claims that cover the applicant’s product
or method of therapeutic use. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the FDA’s Approved
Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by
potential  generic  competitors  in  support  of  approval  of  an  ANDA.  The  ANDA  requests  permission  to  market  a  drug  product  that  has  the  same  active
ingredients in the same strengths and dosage form as the RLD and has been shown through bioequivalence testing to be therapeutically equivalent to the
RLD. Other than the requirement for bioequivalence testing, ANDA applicants are not required to conduct, or submit results of, nonclinical or clinical tests
to prove the safety or effectiveness of their drug product. Drugs approved in this way are commonly referred to as “generic equivalents” to the innovator
drug, and can often be substituted by pharmacists under prescriptions written for the original listed drug referenced by the ANDA applicant if the FDA’s
listing for the generic drug in the Orange Book indicates that it is “therapeutically equivalent” to the RLD.

In contrast, Section 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies not conducted
by or for the applicant and for which the applicant has not obtained a right of reference. A Section 505(b)(2) applicant may eliminate the need to conduct
certain preclinical or clinical studies, if it can establish that reliance on studies conducted for a previously-approved product is scientifically appropriate.
Unlike the ANDA pathway used by developers of bioequivalent versions of innovator drugs, which does not allow applicants to submit new clinical data
other than bioavailability or bioequivalence data, the 505(b)(2) regulatory pathway does not preclude the possibility that a follow-on applicant would need
to  conduct  additional  clinical  trials  or  nonclinical  studies;  for  example,  it  may  be  seeking  approval  to  market  a  previously  approved  drug  for  new
indications or for a new patient population that would require new clinical data to demonstrate safety or effectiveness.

When an ANDA applicant submits its application to the FDA, it is required to certify to the FDA concerning any patents listed for the approved product in
the FDA’s Orange Book. Specifically, the applicant must certify that: (i) the required patent information has not been filed; (ii) the listed patent has expired;
(iii) the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or (iv) the listed patent is invalid or
will not be infringed by the new product. The ANDA applicant may also elect to submit a section viii statement, certifying that its proposed ANDA label
does  not  contain  or  carve  out  any  language  regarding  the  patented  method-of-use,  rather  than  certify  to  a  listed  method-of-use  patent.  Moreover,  to the
extent that the Section 505(b)(2) NDA applicant is relying on studies conducted for an already approved product, the applicant also is required to certify to
the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA applicant would. 

If  the  applicant  does  not  challenge  the  innovator’s  listed  patents,  FDA  will  not  approve  the  ANDA  or  505(b)(2)  application  until  all  the  listed  patents
claiming the referenced product have expired. A certification that the new product will not infringe the already approved product’s listed patents, or that
such patents are invalid, is called a Paragraph IV certification. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant
must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA
and  patent  holders  may  then  initiate  a  patent  infringement  lawsuit  in  response  to  the  notice  of  the  Paragraph  IV  certification.  The  filing  of  a  patent
infringement  lawsuit  within  45  days  of  the  receipt  of  a  Paragraph  IV  certification  automatically  prevents  the  FDA  from  approving  the  ANDA  until  the
earlier of 30 months, expiration of the patent, settlement of the lawsuit, or a decision in the infringement case that is favorable to the ANDA applicant.

An  ANDA  or  505(b)(2)  application  also  will  not  be  approved  until  any  applicable  non-patent  exclusivity  listed  in  the  Orange  Book  for  the  referenced
product has expired.

Non-Patent Exclusivity

Upon NDA approval of a new chemical entity or NCE, which is a drug that contains no active moiety that has been approved by the FDA in any other
NDA, that drug receives five years of marketing exclusivity during which time the FDA cannot receive any ANDA seeking approval of a generic version
of that drug. Certain changes to a drug, such as the addition of a new indication to the package insert or a different formulation, are associated with a three-
year period of exclusivity. During the exclusivity period, the FDA cannot accept for review any ANDA or 505(b)(2) NDA submitted by another company
for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However,  an
application may be submitted one year before NCE exclusivity expires if a Paragraph IV certification is filed on an NCE patent and any time after approval
if the application is filed based on a new indication or a new formulation.

22

The  Hatch-Waxman  Act  also  provides  three  years  of  data  exclusivity  for  a  NDA,  505(b)(2)  NDA  or  supplement  to  an  existing  NDA  if  new  clinical
investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval
of  the  application,  for  example,  new  indications,  dosages  or  strengths  of  an  existing  drug.  This  three-year  exclusivity  covers  only  the  conditions  of  use
associated  with  the  new  clinical  investigations  and  does  not  prohibit  the  FDA  from  approving  follow-on  applications  for  drugs  containing  the  original
active agent. If there is no listed patent in the Orange Book, there may not be a Paragraph IV certification, and, thus, no ANDA or 505(b)(2) NDA may be
filed before the expiration of the exclusivity period. Five-year and three-year exclusivity also will not delay the submission or approval of a traditional
NDA filed under Section 505(b)(1) of the FDC Act. However, an applicant submitting a traditional NDA would be required to either conduct or obtain a
right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Patent term extension

After  NDA  approval,  owners  of  relevant  drug  patents  may  apply  for  up  to  a  five-year  patent  term  extension.  The  allowable  patent  term  extension  is
calculated as half of the drug’s testing phase—the time between when the IND becomes effective and NDA submission—and all of the review phase—the
time  between  NDA  submission  and  approval,  up  to  a  maximum  of  five  years.  The  time  can  be  shortened  if  FDA  determines  that  the  applicant  did  not
pursue approval with due diligence. The total patent term after the extension may not exceed 14 years.

For patents that might expire during the application phase, the patent owner may request an interim patent extension. An interim patent extension increases
the patent term by one year and may be renewed up to four times. For each interim patent extension granted, the post-approval patent extension is reduced
by one year. The director of the Patent and Trademark Office (PTO) must determine that approval of the drug covered by the patent for which a patent
extension is being sought is likely. Interim patent extensions are not available for a drug for which an NDA has not been submitted.

Pediatric clinical trials and exclusivity

Under the Pediatric Research Equity Act, or PREA, NDAs or certain types of supplements to NDAs must contain data to assess the safety and effectiveness
of the drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for
which the drug is safe and effective. The sponsor must submit an initial Pediatric Study Plan, or PSP, within 60 days of an end-of-phase 2 meeting or as
may be agreed between the sponsor and the FDA. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct,
including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information,
and  any  request  for  a  deferral  of  pediatric  assessments  or  a  full  or  partial  waiver  of  the  requirement  to  provide  data  from  pediatric  studies  along  with
supporting information. The FDA and the sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at
any time if changes to the pediatric plan need to be considered based on data collected from nonclinical studies, early phase clinical trials, and/or other
clinical development programs. The FDA may grant full or partial waivers, or deferrals, for submission of pediatric assessment data.

The Best Pharmaceuticals for Children Act, or BPCA, provides NDA holders a six-month extension of any exclusivity—patent or non-patent—for a drug if
certain conditions are met, including satisfaction of a pediatric trial(s) agreed with FDA as a Pediatric Written Request. Conditions for pediatric exclusivity
include  the  FDA’s  determination  that  information  relating  to  the  use  of  a  new  drug  in  the  pediatric  population  may  produce  health  benefits  in  that
population, the FDA making a written request for pediatric clinical trials, and the applicant agreeing to perform, and reporting on, the requested clinical
trials within the statutory timeframe. Applications under the BPCA are treated as priority applications, with all of the benefits that designation confers. This
six-month  exclusivity  may  be  granted  if  an  NDA  sponsor  submits  pediatric  data  that  fairly  respond  to  the  written  request  from  the  FDA  for  such  data.
Those data do not need to show the product to be effective in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the
FDA’s request, the additional protection is granted. Although this is not a patent term extension, it effectively extends the regulatory period during which
the FDA cannot approve another application.

Fast track, breakthrough therapy, and priority review designations

The FDA is authorized to designate certain products for expedited development or review if they are intended to address an unmet medical need in the
treatment of a serious or life-threatening disease or condition. These programs include fast track designation, breakthrough therapy designation, and priority
review designation. Even if a drug qualifies for one or more of these programs, the FDA may later decide that the drug no longer meets the conditions for
qualification or that the time period for FDA review or approval will not be shortened. Generally, drugs that may be eligible for these programs are those
for serious or life-threatening conditions, those with the potential to address unmet medical needs, and those that offer meaningful benefits over existing
treatments. For example, fast track designation is a process designed to facilitate the development, and expedite the review, of drugs to treat serious or life-
threatening diseases and fill an unmet medical need. The designation request may be made at the time of IND submission and generally no later than the
pre-NDA  meeting.  The  FDA  will  respond  within  60  calendar  days  of  receipt  of  the  request.  Priority  review,  which  is  requested  at  the  time  of  NDA
submission, is designed to give drugs that offer major advances in treatment or

23

provide a treatment where no adequate therapy exists, an initial review within six months after filing as compared to a standard review time of ten months.
Although fast track designation and priority review do not affect the standards for approval, the FDA will attempt to facilitate early and frequent meetings
with  a  sponsor  of  a  fast  track  designated  drug  and  expedite  review  of  the  application  for  a  drug  designated  for  priority  review.  Accelerated  approval
provides an earlier approval of drugs to treat serious diseases, and that fill an unmet medical need based on a surrogate endpoint, which is a laboratory
measurement or physical sign used as an indirect or substitute measurement representing a clinically meaningful outcome. Discussions with the FDA about
the  feasibility  of  an  accelerated  approval  typically  begin  early  in  the  development  of  the  drug  in  order  to  identify,  among  other  things,  an  appropriate
endpoint. As a condition of approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform post-marketing clinical trials to
confirm the appropriateness of the surrogate marker clinical trial.

Another  expedited  program  is  that  for  breakthrough  therapy  designation,  which  is  designed  to  expedite  the  development  and  review  of  drugs  that  are
intended to treat a serious condition where preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available
therapy on a clinically significant endpoint(s). A sponsor may request breakthrough therapy designation at the time that the IND is submitted, or no later
than at the end-of-Phase 2 meeting. The FDA will respond to a breakthrough therapy designation request within sixty days of receipt of the request. A drug
that  receives  breakthrough  therapy  designation  is  eligible  for  all  fast  track  designation  features,  intensive  guidance  on  an  efficient  drug  development
program, beginning as early as Phase 1, and commitment from the FDA involving senior managers. Products that are designated as Breakthrough therapies
with priority review are often given preclinical or clinical post-marketing requirements or post marketing commitments by the FDA.

Accelerated approval pathway
In  addition,  products  studied  for  their  safety  and  effectiveness  in  treating  serious  or  life-threatening  illnesses  and  that  provide  meaningful  therapeutic
benefit over existing treatments may receive accelerated approval from the FDA and may be approved on the basis of adequate and well-controlled clinical
trials establishing that the drug product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit. A surrogate endpoint is a
laboratory measurement or physical sign used as an indirect or substitute measurement representing a clinically meaningful outcome. Surrogate endpoints
can often be measured more easily or more rapidly than clinical endpoints. The FDA may also grant accelerated approval for such a drug when the product
has an effect on an intermediate clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality, or IMM, and that is
reasonably  likely  to  predict  an  effect  on  IMM  or  other  clinical  benefit,  taking  into  account  the  severity,  rarity,  or  prevalence  of  the  condition  and  the
availability or lack of alternative treatments. The FDA has limited experience with accelerated approvals based on intermediate clinical endpoints, but has
indicated  that  such  endpoints  generally  may  support  accelerated  approval  when  the  therapeutic  effect  measured  by  the  endpoint  is  not  itself  a  clinical
benefit and basis for traditional approval, if there is a basis for concluding that the therapeutic effect is reasonably likely to predict the ultimate long-term
clinical benefit of a drug.

Discussions with the FDA about the feasibility of an accelerated approval typically begin early in the development of the drug in order to identify, among
other  things,  an  appropriate  endpoint.  The  accelerated  approval  pathway  is  most  often  used  in  settings  in  which  the  course  of  a  disease  is  long  and  an
extended period of time is required to measure the intended clinical benefit of a drug, even if the effect on the surrogate or intermediate clinical endpoint
occurs rapidly. For example, accelerated approval has been used extensively in the development and approval of drugs for treatment of a variety of cancers
in  which  the  goal  of  therapy  is  generally  to  improve  survival  or  decrease  morbidity  and  the  duration  of  the  typical  disease  course  requires  lengthy  and
sometimes large clinical trials to demonstrate a clinical or survival benefit.

As a condition of approval, the FDA may require that a sponsor of a drug receiving accelerated approval perform post-marketing clinical trials to verify and
describe the predicted effect on IMM or other clinical endpoint. Drugs granted accelerated approval must meet the same statutory standards for safety and
effectiveness as those granted traditional approval. Because the accelerated approval pathway is usually contingent on a sponsor’s agreement to conduct, in
a  diligent  manner,  additional  post-approval  confirmatory  studies  to  verify  and  describe  the  drug’s  clinical  benefit,  a  product  candidate  approved  on  this
basis  is  subject  to  rigorous  post-marketing  compliance  requirements,  including  the  completion  of  Phase  4  or  post-approval  clinical  trials  to  confirm  the
effect on the clinical endpoint. Failure to conduct required post-approval studies, or to confirm the predicted clinical benefit of the product during post-
marketing studies, would allow the FDA to withdraw approval of the drug. In addition, all promotional materials for product candidates being considered
and approved under the accelerated approval program are subject to prior review by the FDA.

Regulation of companion diagnostic devices

If we decide that a diagnostic test would provide useful information for patient selection or if the FDA requires us to develop such a test, we may work with
a  collaborator  to  develop  an  in  vitro  diagnostic,  or  companion  test.  The  FDA  regulates  in  vitro  diagnostic  tests  as  medical  devices,  and  the  type  of
regulation to which such a test will be subjected will depend, in part, on a risk assessment by the FDA as well as a determination of whether the test is
intended to yield results that would be helpful to know versus one that the FDA or we believe is necessary to know for the safe and effective use of our
drugs under development.

24

 
 
 
The  FDA  has  issued  several  guidance  documents  on  in  vitro  companion  diagnostic  devices  in  August  2014,  which  are  intended  to  assist  companies
developing in vitro companion diagnostic devices and companies developing therapeutic products that depend on the use of a specific in vitro companion
diagnostic for the safe and effective use of the product. The FDA defines an in vitro companion diagnostic device, or IVD companion diagnostic device, as
a device that provides information that is essential for the safe and effective use of a corresponding therapeutic product, such as when the use of a product
is limited to a specific patient subpopulation that can be identified by using the test. The use of an IVD companion diagnostic device with a therapeutic
product will be stipulated in the instructions for use in the labeling of both the diagnostic device and the corresponding therapeutic product, including the
labeling of any generic equivalents of the therapeutic product. The FDA expects that the therapeutic product sponsor will address the need for an approved
or  cleared  IVD  companion  diagnostic  device  in  its  therapeutic  product  development  plan  and  that,  in  most  cases,  the  therapeutic  product  and  its
corresponding companion diagnostic will be developed contemporaneously. However, the FDA may decide that it is appropriate to approve such a product
without an approved or cleared in vitro companion diagnostic device when the drug or therapeutic biologic is intended to treat a serious or life-threatening
condition for which no satisfactory alternative treatment exists and the FDA determines that the benefits from the use of a product with an unapproved or
uncleared in vitro companion diagnostic device are so pronounced as to outweigh the risks from the lack of an approved or cleared in  vitro  companion
diagnostic device. The FDA encourages sponsors considering developing a therapeutic product that requires a companion diagnostic to request a meeting
with both relevant device and therapeutic product review divisions to ensure that the product development plan will produce sufficient data to establish the
safety and effectiveness of both the therapeutic product and the companion diagnostic. Because the FDA’s policies on companion diagnostics is set forth
only in guidance, this policy is subject to change and is not legally binding.

Post-approval requirements
Following FDA marketing approval of a new prescription drug product, the manufacturer and the approved drug are subject to pervasive and continuing
regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting of adverse experiences with the product, product
sampling  and  distribution  restrictions,  complying  with  promotion  and  advertising  requirements,  which  include  restrictions  on  promoting  drugs  for
unapproved  uses  or  patient  populations  (i.e.,  “off-label  use”)  and  limitations  on  industry-sponsored  scientific  and  educational  activities.  Although
physicians may prescribe legally available products for off-label uses, manufacturers may not market or promote such uses. 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.  If  there  are  any  modifications  to  the  product,  including  changes  in  indications,  labeling  or  manufacturing
processes or facilities, the applicant may be required to submit and obtain FDA approval of a new NDA or an NDA supplement, which may require the
applicant to develop additional data or conduct additional preclinical studies and clinical trials.

Once  an  approval  is  granted,  the  FDA  may  withdraw  the  approval  if  compliance  with  regulatory  requirements  and  standards  is  not  maintained  or  if
problems occur after the drug product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of
unanticipated severity or frequency, may result in in mandatory revisions to the approved labeling to add new safety information; imposition of post-market
or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences include,
among other things:

■
■
■
■
■
■

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;
fines, warning letters or other enforcement-related letters or clinical holds on post-approval clinical trials;
refusal of the FDA to approve pending NDAs or supplements to approved NDAs, or suspension or revocation of product approvals;
product seizure or detention, or refusal to permit the import or export of products;
injunctions or the imposition of civil or criminal penalties; and
consent  decrees,  corporate  integrity  agreements,  debarment,  or  exclusion  from  federal  health  care  programs;  or  mandated  modification  of
promotional materials and labeling and the issuance of corrective information.

Accordingly,  COSELA  and  any  future  therapeutic  candidate  manufactured  or  distributed  by  us  pursuant  to  FDA  approvals  are  subject  to  continuing
regulation by the FDA, including, among other things:

■
■
■
■
■
■

record-keeping requirements;
reporting of adverse experiences with the therapeutic candidate;
providing the FDA with updated safety and efficacy information;
therapeutic sampling and distribution requirements;
notifying the FDA and gaining its approval of specified manufacturing or labeling changes; and
complying with FDA promotion and advertising requirements, which include, among other things, standards for direct-to-consumer advertising,
restrictions  on  promoting  products  for  uses  or  in-patient  populations  that  are  not  described  in  the  product’s  approved  labeling,  limitations  on
industry-sponsored scientific and educational activities and requirements for promotional activities involving the internet.

25

 
 
 
 
 
 
 
 
 
 
 
 
 
FDA  regulations  require  that  products  be  manufactured  in  specific  approved  facilities  and  in  accordance  with  cGMPs.  The  cGMP  regulations  include
requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product containers and closures,
production  and  process  controls,  packaging  and  labeling  controls,  holding  and  distribution,  laboratory  controls,  records  and  reports  and  returned  or
salvaged products. Drug manufacturers and other entities involved in the manufacture and distribution of approved drug 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 some state agencies for
compliance  with  cGMPs  and  other  laws.  The  FDA  periodically  inspects  manufacturing  facilities  to  assess  compliance  with  cGMP  requirements.  In
addition, changes to the manufacturing process are strictly regulated, and, depending on the significance of the change, may require FDA approval before
being  implemented.  FDA  regulations  also  require  investigation  and  correction  of  any  deviations  from  cGMP  and  impose  reporting  and  documentation
requirements upon the NDA applicant and any third-party manufacturers involved in producing the approved drug product. Accordingly, manufacturers
must  continue  to  expend  time,  money  and  effort  in  the  area  of  production  and  quality  control  to  maintain  compliance  with  cGMP  and  other  aspects  of
quality control and quality assurance.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or the PDMA, which regulates the
distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states.
Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples and impose requirements to ensure accountability in
distribution. Most recently, the Drug Supply Chain Security Act, or the DSCSA, was enacted with the aim of building an electronic system to identify and
trace  certain  prescription  drugs  distributed  in  the  United  States,  including  most  biological  products.  The  DSCSA  mandates  phased-in  and  resource-
intensive  obligations  for  pharmaceutical  manufacturers,  wholesale  distributors,  and  dispensers  over  a  10‑year  period  that  is  expected  to  culminate  in
November 2023. From time to time, new legislation and regulations may be implemented that could significantly change the statutory provisions governing
the approval, manufacturing and marketing of products regulated by the FDA. It is impossible to predict whether further legislative or regulatory changes
will be enacted, or FDA regulations, guidance or interpretations changed or what the impact of such changes, if any, may be.

Europe/Rest of world government regulation

In addition to regulations in the United States, we are and will be subject, either directly or through our distribution partners, to a variety of regulations in
other  jurisdictions  governing,  among  other  things,  clinical  trials,  the  privacy  of  personal  data  and  commercial  sales  and  distribution  of  our  products,  if
approved.

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in non-U.S. countries prior to the
commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the United States have a process that requires
the submission of a clinical trial application much like an IND prior to the commencement of human clinical trials. In Europe, for example, a clinical trial
application,  or  CTA,  must  be  submitted  to  the  competent  national  health  authority  and  to  independent  ethics  committees  in  each  country  in  which  a
company plans to conduct clinical trials. Once the CTA is approved in accordance with a country’s requirements, clinical trials may proceed in that country.

The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country, even
though there is already some degree of legal harmonization in the European Union member states resulting from the national implementation of underlying
E.U. legislation. In all cases, the clinical trials are conducted in accordance with GCP and other applicable regulatory requirements.

To obtain a marketing license for a new drug, or medicinal product in the European Union, the sponsor must obtain approval of a marketing authorization
application, or MAA. The way in which a medicinal product can be approved in the European Union depends on the nature of the medicinal product.

The centralized procedure results in a single marketing authorization granted by the European Commission that is valid across the European Union, as well
as in Iceland, Liechtenstein, and Norway. The centralized procedure is compulsory for human drugs that are: (i) derived from biotechnology processes,
such  as  genetic  engineering,  (ii)  contain  a  new  active  substance  indicated  for  the  treatment  of  certain  diseases,  such  as  HIV/AIDS,  cancer,  diabetes,
neurodegenerative diseases, autoimmune and other immune dysfunctions and viral diseases, (iii) officially designated “orphan drugs” (drugs used for rare
human  diseases)  and  (iv)  advanced-therapy  medicines,  such  as  gene-therapy,  somatic  cell-therapy  or  tissue-engineered  medicines.  The  centralized
procedure may at the request of the applicant also be used for human drugs which do not fall within the above mentioned categories if the human drug
(a) contains a new active substance which was not authorized in the European Community; or (b) the applicant shows that the medicinal product constitutes
a significant therapeutic, scientific or technical innovation or that the granting of authorization in the centralized procedure is in the interests of patients or
animal health at the European Community level.

Under  the  centralized  procedure  in  the  European  Union,  the  maximum  timeframe  for  the  evaluation  of  a  marketing  authorization  application  by  the
European Medicines Agency, or EMA, is 210 days (excluding clock stops, when additional written or oral information is to be provided by the applicant in
response to questions asked by the Committee for Medicinal Products for Human Use, or CHMP), with adoption of the actual marketing authorization by
the European Commission thereafter. Accelerated evaluation

26

might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public health interest from the point of view of
therapeutic  innovation,  defined  by  three  cumulative  criteria:  the  seriousness  of  the  disease  to  be  treated;  the  absence  of  an  appropriate  alternative
therapeutic approach, and anticipation of exceptional high therapeutic benefit. In this circumstance, EMA ensures that the evaluation for the opinion of the
CHMP is completed within 150 days and the opinion issued thereafter.

The  mutual  recognition  procedure,  or  MRP,  for  the  approval  of  human  drugs  is  an  alternative  approach  to  facilitate  individual  national  marketing
authorizations within the European Union. Basically, the MRP may be applied for all human drugs for which the centralized procedure is not obligatory.
The  MRP  is  applicable  to  the  majority  of  conventional  medicinal  products,  and  is  based  on  the  principle  of  recognition  of  an  already  existing  national
marketing authorization by one or more member states. In the MRP, a marketing authorization for a drug already exists in one or more member states of the
E.U.  and  subsequently  marketing  authorization  applications  are  made  in  other  European  Union  member  states  by  referring  to  the  initial  marketing
authorization. The member state in which the marketing authorization was first granted will then act as the reference member state. The member states
where the marketing authorization is subsequently applied for act as concerned member states. After a product assessment is completed by the reference
member  state,  copies  of  the  report  are  sent  to  all  member  states,  together  with  the  approved  summary  of  product  characteristics,  labeling  and  package
leaflet.  The  concerned  member  states  then  have  90  days  to  recognize  the  decision  of  the  reference  member  state  and  the  summary  of  product
characteristics,  labeling  and  package  leaflet.  National  marketing  authorizations  within  individual  member  states  shall  be  granted  within  30  days  after
acknowledgement of the agreement

Should any member state refuse to recognize the marketing authorization by the reference member state, on the grounds of potential serious risk to public
health,  the  issue  will  be  referred  to  a  coordination  group.  Within  a  timeframe  of  60  days,  member  states  shall,  within  the  coordination  group,  make  all
efforts to reach a consensus. If this fails, the procedure is submitted to an EMA scientific committee for arbitration. The opinion of this EMA committee is
then forwarded to the Commission, for the start of the decision-making process. As in the centralized procedure, this process entails consulting various
European Commission Directorates General and the Standing Committee on Human Medicinal Products or Veterinary Medicinal Products, as appropriate.

For  countries  outside  of  the  European  Union,  such  as  countries  in  Eastern  Europe,  Latin  America  or  Asia,  the  requirements  governing  the  conduct  of
clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical trials are conducted in accordance
with GCP and the other applicable regulatory requirements.

If  we  fail  to  comply  with  applicable  foreign  regulatory  requirements,  we  may  be  subject  to,  among  other  things,  fines,  suspension  of  clinical  trials,
suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions, and criminal prosecution.

Europe - Data Privacy

On May 25, 2018, the European General Data Protection Regulation, or GDPR, went into effect, implementing a broad data protection framework that
expanded the scope of EU data protection law, including to non-EU entities that process, or control the processing of, personal data relating to individuals
located in the EU, including clinical trial data.  The  GDPR sets out a number of requirements that must be complied with when handling the personal data
of  European  Union-based  data  subjects  including:  providing  expanded  disclosures  about  how  their  personal  data  will  be  used;  higher  standards  for
organizations  to  demonstrate  that  they  have  obtained  valid  consent  or  have  another  legal  basis  in  place  to  justify  their  data  processing  activities;  the
obligation to appoint data protection officers in certain circumstances; new rights for individuals to be “forgotten” and rights to data portability, as well as
enhanced  current  rights  (e.g.  access  requests);  the  principal  of  accountability  and  demonstrating  compliance  through  policies,  procedures,  training  and
audit; and a new mandatory data breach regime. In particular, medical or health data, genetic data and biometric data where the latter is used to uniquely
identify  an  individual  are  all  classified  as  “special  category”  data  under  the  GDPR  and  afforded  greater  protection  and  require  additional  compliance
obligations.  Further,  EU  member  states  have  a  broad  right  to  impose  additional  conditions—including  restrictions—on  these  data  categories.  This  is
because the GDPR allows EU member states to derogate from the requirements of the GDPR mainly in regard to specific processing situations (including
special category data and processing for scientific or statistical purposes). As the EU states continue to reframe their national legislation to harmonize with
the GDPR, we will need to monitor compliance with all relevant EU member states’ laws and regulations, including where permitted derogations from the
GDPR are introduced.

We will also be subject to evolving EU laws on data export, if we transfer data outside the EU to ourselves or third parties outside of the EU. The GDPR
only permits exports of data outside the EU where there is a suitable data transfer solution in place to safeguard personal data (e.g. the European Union
Commission  approved  Standard  Contractual  Clauses).  On  July  16,  2020,  the  Court  of  Justice  of  the  European  Union  or  the  CJEU,  issued  a  landmark
opinion  in  the  case  Maximilian  Schrems  vs.  Facebook  (Case  C-311/18),  called  Schrems  II.    This  decision  calls  into  question  certain  data  transfer
mechanisms as between the EU member states and the US.   The CJEU is the highest court in Europe and the Schrems II decision heightens the burden on
data  importers  to  assess  U.S.  national  security  laws  on  their  business  and  future  actions  of  EU  data  protection  authorities  are  difficult  to  predict.   
Consequently, there is some risk of any data transfers from the European Union being halted.   If we have to rely on third parties to carry out services for
us,

27

 
 
 
including processing personal data on our behalf, we are required under GDPR to enter into contractual arrangements to help ensure that these third parties
only  process  such  data  according  to  our  instructions  and  have  sufficient  security  measures  in  place.  Any  security  breach  or  non-compliance  with  our
contractual terms or breach of applicable law by such third parties could result in enforcement actions, litigation, fines and penalties or adverse publicity
and could cause customers to lose trust in us, which would have an adverse impact on our reputation and business.  Any contractual arrangements requiring
the transfer of personal data from the EU to us in the United States will require greater scrutiny and assessments as required under Schrems II and may have
an adverse impact on cross-border transfers of personal data, or increase costs of compliance.  The GDPR provides an enforcement authority to impose
large penalties for noncompliance, including the potential for fines of up to €20 million or 4% of the annual global revenues of the noncompliant company,
whichever  is  greater.    We  will  be  subject  to  the  GDPR  when  we  have  a  European  Union  presence  or  “establishment”  (e.g.,  EU  based  subsidiary  or
operations), when conducting clinical trials with EU based data subjects, whether the trials are conducted directly by us or through a vendor or partner, or
offering approved products or services to EU-based data subjects, regardless of whether involving a EU based subsidiary or operations.  

Pharmaceutical Coverage, Pricing, and Reimbursement

Sales  of  our  products  that  are  approved  by  the  FDA  will  depend,  in  part,  on  the  extent  to  which  the  products  will  be  covered  by  third-party  payors,
including government health programs in the United States such as Medicare and Medicaid, commercial health insurers, and managed care organizations.
The process for determining whether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement
rate that the payor will pay for the product once coverage is approved, and it is time consuming and expensive to seek reimbursement from third-party
payors. Third-party payors may limit coverage to specific products on an approved list, or formulary, which might not include all of the approved products
for a particular indication. Coverage may be more limited than the purposes for which the product is approved by the FDA or regulatory authorities in other
countries.

In  order  to  secure  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  a  company  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain
FDA or other comparable regulatory approvals. A payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement
rate will be approved. Moreover, eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers our costs,
including research, development, manufacture, sale and distribution. Interim payments for new products, if applicable, may also not be sufficient to cover
our costs and may not be made permanent. Payment rates may vary according to the use of the product and the clinical setting in which it is used, may be
based on payments allowed for lower cost products that are already reimbursed and may be incorporated into existing payments for other services. Net
prices for products may be reduced by mandatory discounts or rebates required by third-party payors and by any future relaxation of laws that presently
restrict imports of products from countries where they may be sold at lower prices than in the United States. In the U.S., third-party payors often rely upon
Medicare coverage policy and payment limitations in setting their own reimbursement policies, but they also have their own methods and approval process
apart from Medicare coverage and reimbursement determinations. Accordingly, one third-party payor’s determination to provide coverage for a product
does not assure that other payors will also provide coverage for the product.

In addition, the containment of healthcare costs has become a priority of federal and state governments and the prices of therapeutics have been a focus in
this  effort.  The  United  States  government,  state  legislatures  and  foreign  governments  have  shown  significant  interest  in  implementing  cost-containment
programs,  including  price  controls,  restrictions  on  reimbursement  and  requirements  for  substitution  of  generic  products.  Adoption  of  price  controls  and
cost-containment  measures,  and  adoption  of  more  restrictive  policies  in  jurisdictions  with  existing  controls  and  measures,  could  further  limit  our  net
revenue  and  results.  If  these  third-party  payors  do  not  consider  our  products  to  be  cost-effective  compared  to  other  therapies,  they  may  not  cover  our
products  after  approval  as  a  benefit  under  their  plans  or,  if  they  do,  the  level  of  payment  may  not  be  sufficient  to  allow  us  to  sell  our  products  on  a
profitable basis. Moreover, companion diagnostic tests require coverage and reimbursement separate and apart from the coverage and reimbursement for
their  companion  pharmaceutical  products.  Similar  challenges  to  obtaining  coverage  and  reimbursement  for  the  pharmaceutical  products  apply  to
companion diagnostics.

In  the  European  Union,  pricing  and  reimbursement  schemes  vary  widely  from  country  to  country.  Some  countries  provide  that  drug  products  may  be
marketed  only  after  a  reimbursement  price  has  been  agreed.  Some  countries  may  require  the  completion  of  additional  studies  that  compare  the  cost-
effectiveness of our product candidate to currently available therapies (so called health technology assessment, or HTA) in order to obtain reimbursement
or pricing approval. For example, the European Union provides options for its member states to restrict the range of drug products for which their national
health insurance systems provide reimbursement and to control the prices of medicinal products for human use. E.U. member states may approve a specific
price for a drug product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the drug product on the
market. Other member states allow companies to fix their own prices for drug products but monitor and control prescription volumes and issue guidance to
physicians to limit prescriptions. The downward pressure on health care costs in general, particularly prescription drugs, has become intense. As a result,
increasingly  high  barriers  are  being  erected  to  the  entry  of  new  products.  In  addition,  there  can  be  considerable  pressure  by  governments  and  other
stakeholders on prices and reimbursement levels, including as part of cost

28

containment  measures.  Political,  economic  and  regulatory  developments  may  further  complicate  pricing  negotiations,  and  pricing  negotiations  may
continue after reimbursement has been obtained. Reference pricing used by various E.U. member states, and parallel distribution (arbitrage between low-
priced and high-priced member states), can further reduce prices. Any country that has price controls or reimbursement limitations for drug products may
not  allow  favorable  reimbursement  and  pricing  arrangements.  There  can  be  no  assurance  that  any  country  that  has  price  controls  or  reimbursement
limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our product candidates that are approved
for commercial marketing and distribution. Historically, therapeutic candidates launched in the European Union do not follow price structures of the United
States and generally tend to be significantly lower.

Other Healthcare Laws and Regulations

As we are commercializing COSELA and may commercialize other product candidates, we are subject to additional healthcare statutory and regulatory
requirements and enforcement by federal government and the states and foreign governments in the jurisdictions in which we conduct our business.
Healthcare providers, physicians and third-party payors play a primary role in the recommendation and prescription of COSELA and any other product
candidates for which we obtain marketing approval. Our arrangements with third-party payors and customers expose us to broadly applicable fraud and
abuse and other healthcare laws and regulations that constrain the business or financial arrangements and relationships through which we market, sell and
distribute any products for which we obtain marketing approval.

Restrictions under applicable federal and state healthcare laws and regulations include the following:

• The federal Anti-Kickback Statute prohibits, among other things, any person from knowingly and willfully offering, soliciting, receiving or
providing  remuneration,  directly  or  indirectly,  to  induce  either  the  referral  of  an  individual,  for  an  item  or  service  or  the  purchasing  or
ordering  of  a  good  or  service,  for  which  payment  may  be  made  under  federal  healthcare  programs  such  as  the  Medicare  and  Medicaid
programs. The federal Anti-Kickback Statute is subject to evolving interpretations. In the past, the government has enforced the federal Anti-
Kickback  Statute  to  reach  large  settlements  with  healthcare  companies  based  on  sham  consulting  and  other  financial  arrangements  with
physicians. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed
a violation. In addition, the government may assert that 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 civil False Claims Act;

• The federal civil and criminal false claims laws, including the civil False Claims Act, and civil monetary penalty laws, prohibit, among other
things,  knowingly  presenting  or  causing  the  presentation  of  a  false,  fictitious  or  fraudulent  claim  for  payment  to  the  U.S.  government,
knowingly  making,  using,  or  causing  to  be  made  or  used  a  false  record  or  statement  material  to  a  false  or  fraudulent  claim  to  the  U.S.
government, or from knowingly making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. government.
Actions  under  these  laws  may  be  brought  by  the  Attorney  General  or  as  a  qui  tam  action  by  a  private  individual  in  the  name  of  the
government. The federal government uses these laws, and the accompanying threat of significant liability, in its investigation and prosecution
of  pharmaceutical  and  biotechnology  companies  throughout  the  U.S.,  for  example,  in  connection  with  the  promotion  of  products  for
unapproved uses and other allegedly unlawful sales and marketing practices;

• The U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created new federal, civil and criminal statutes that
prohibit  among  other  actions,  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit
program, including private 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, concealing or covering up a material fact
or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items
or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific
intent to violate it in order to have committed a violation;

• The  Physician  Payments  Sunshine  Act,  enacted  as  part  of  the  Affordable  Care  Act  of  2010,  among  other  things,  imposes  reporting
requirements  on  manufacturers  of  FDA-approved  drugs,  devices,  biologics  and  medical  supplies  covered  by  Medicare,  Medicaid,  or  the
Children’s Health Insurance Program to report, on an annual basis, to the Centers for Medicare & Medicaid Services, or CMS, information
related  to  payments  and  other  transfers  of  value  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists,  chiropractors
and, beginning in 2022 for payments and other transfers of value provided in the previous year, certain advanced non-physician health care
practitioners), teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members;

29

 
 
 
 
 
 
 
 
• HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  or  HITECH,  and  their  respective
implementing regulations impose specified requirements relating to the privacy, security and transmission of individually identifiable health
information.  Among  other  things,  HITECH  makes  HIPAA’s  privacy  and  security  standards  directly  applicable  to  “business  associates,”
defined  as  independent  contractors  or  agents  of  covered  entities,  which  include  certain  healthcare  providers,  health  plans,  and  healthcare
clearinghouses, that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf
of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates
and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to
enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions;

• Analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, that 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  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 and may require drug manufacturers to report information related to
payments and other transfers of value to physicians and other healthcare providers or marketing expenditures to the extent that those laws
impose  requirements  that  are  more  stringent  than  the  Physician  Payments  Sunshine  Act,  as  well  as  state  and  local  laws  that  require  the
registration of pharmaceutical sales representatives; and

State  laws  and  foreign  laws  and  regulations  (particularly  European  Union  laws  regarding  personal  data  relating  to  individuals  based  in
Europe)  that  govern  the  privacy  and  security  of  health  information  in  certain  circumstances,  many  of  which  differ  from  each  other  in
significant ways, thus complicating compliance efforts.

Moreover, in November 2020, the Department of Health and Human Services (“DHHS”) finalized significant changes to the regulations implementing the
Anti-Kickback Statute, as well as the Physician Self-Referral Law (Stark Law) and the civil monetary penalty rules regarding beneficiary inducements,
with  the  goal  of  offering  the  healthcare  industry  more  flexibility  and  reducing  the  regulatory  burden  associated  with  those  fraud  and  abuse  laws,
particularly with respect to value-based arrangements among industry participants. As noted below under “Healthcare Reform,” however, those final rules
may be potentially overturned under the Congressional Review Act following the change in control of the legislative and executive branches in January
2021.

Ensuring that our current and future business arrangements with third parties comply with applicable healthcare laws and regulations involve substantial
costs.  It  is  possible  that  governmental  authorities  may  conclude  that  our  business  practices  may  not  comply  with  current  or  future  statutes,  regulations,
agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of
any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties,
including  monetary  damages,  fines,  disgorgement,  imprisonment,  loss  of  eligibility  to  obtain  approvals  from  the  FDA,  exclusion  from  participation  in
government contracting, healthcare reimbursement or other government programs, including Medicare and Medicaid, reputational harm, diminished profits
and future earnings, or additional reporting requirements if we become subject to a corporate integrity agreement or other agreement to resolve allegations
of non-compliance with any of these laws, and the curtailment or restructuring of our operations. If any of the physicians or other healthcare providers or
entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative
sanctions, including exclusions from government funded healthcare programs.

Healthcare Reform and potential changes to drug and healthcare laws

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes
regarding the healthcare system that could prevent or delay marketing approval of product and therapeutic candidates, restrict or regulate post-approval
activities,  and  affect  the  ability  to  profitably  sell  product  and  therapeutic  candidates  that  obtain  marketing  approval.  The  FDA’s  and  other  regulatory
authorities’  policies  may  change  and  additional  government  regulations  may  be  enacted  that  could  prevent,  limit  or  delay  regulatory  approval  of  our
product and therapeutic candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies,
or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we otherwise may have obtained and we may not achieve
or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations. Moreover, among policy makers
and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing
healthcare costs, improving quality and/or expanding access.

For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the ACA,
was enacted in March 2010 and has had a significant impact on the health care industry in the U.S. The ACA expanded coverage for the uninsured while at
the same time containing overall healthcare costs. With regard to biopharmaceutical products, the ACA, among other things, addressed a new methodology
by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or
injected, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to
individuals enrolled in Medicaid managed care organizations, established annual fees on manufacturers of certain branded prescription drugs, and created a
new  Medicare  Part  D  coverage  gap  discount  program.  Additionally,  on  December  20,  2019,  President  Trump  signed  the  Further  Consolidated
Appropriations  Act  for  2020  into  law  (P.L.  116-94)  that  includes  a  piece  of  bipartisan  legislation  called  the  Creating  and  Restoring  Equal  Access  to
Equivalent Samples Act of 2019 or the “CREATES Act.” The CREATES Act aims to address the concern articulated by both the FDA and others in the
industry that some brand manufacturers have improperly restricted the distribution of their products, including by invoking the existence of a REMS for
certain products, to deny generic product developers access to samples of brand products. Because generic product developers need samples to conduct
certain comparative testing required by the FDA, some have attributed the inability to timely obtain samples as a cause of delay in the entry of generic
products.  To  remedy  this  concern,  the  CREATES  Act  establishes  a  private  cause  of  action  that  permits  a  generic  product  developer  to  sue  the  brand
manufacturer  to  compel  it  to  furnish  the  necessary  samples  on  “commercially  reasonable,  market-based  terms.”  Whether  and  how  generic  product
developments will use this new pathway, as well as the likely outcome of any legal challenges to provisions of the CREATES Act, remain highly uncertain
and its potential effects on future competition for COSELA or any of our other future commercial products are unknown.

As another example, the 2021 Consolidated Appropriations Act signed into law on December 27, 2020 incorporated extensive healthcare provisions and
amendments to existing laws, including a requirement that all manufacturers of drugs and biological products covered under Medicare Part B report the
product’s average sales price, or ASP, to DHHS beginning on January 1, 2022, subject to enforcement via civil money penalties.  

Since its enactment, there have been executive, judicial and Congressional challenges to certain aspects of the ACA and we expect there will be additional
challenges and amendments to the ACA in the future. Members of the US Congress have indicated that they may continue to seek to modify, repeal or
otherwise  invalidate  all,  or  certain  provisions  of,  the  ACA.  For  example,  the  Tax  Cuts  and  Jobs  Act,  or  TCJA,  was  enacted  in  2017  and,  among  other
things, removed penalties, starting January 1, 2019, for not complying with the ACA’s individual mandate to carry health insurance, commonly referred to
as  the  “individual  mandate.”  In  December  2018,  a  U.S.  District  Court  Judge  in  the  Northern  District  of  Texas  ruled  that  the  individual  mandate  was  a
critical and inseverable feature of the ACA, and therefore, because it was repealed as part of the TCJA, the remaining provisions of the ACA were invalid
and the law in its entirety was unconstitutional. In December 2019, the U.S. Court of Appeals for the Fifth Circuit upheld the District Court ruling that the
individual mandate was unconstitutional but remanded the case back to the District Court to determine whether other reforms enacted as part of the ACA
but not specifically related to the individual mandate or health insurance could be severed from the rest of the ACA so as not to be declared invalid as well.
On  March  2,  2020,  the  United  States  Supreme  Court  granted  the  petitions  for  writs  of  certiorari  to  review  this  case  and  allocated  one  hour  for  oral
arguments,  which  occurred  on  November  10,  2020.  A  decision  from  the  Supreme  Court  is  expected  to  be  issued  in  spring  2021.  It  is  unclear  how  this
litigation and other efforts to repeal and replace the ACA will impact the implementation of the ACA, the pharmaceutical industry more generally, and our
business.  Complying  with  any  new  legislation  or  reversing  changes  implemented  under  the  ACA  could  be  time-intensive  and  expensive,  resulting  in  a
material adverse effect on our business.

31

In  addition,  other  legislative  changes  have  been  proposed  and  adopted  in  the  United  States  since  the  ACA  that  affect  health  care  expenditures.  These
changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control Act of 2011, which
began in 2013 and will remain in effect through 2030 unless additional Congressional action is taken. The Coronavirus Aid, Relief, and Economic Security
Act, or the CARES Act, which was signed into law on March 27, 2020 and was designed to provide financial support and resources to individuals and
businesses affected by the COVID-19 pandemic, suspended the 2% Medicare sequester from May 1, 2020 through December 31, 2020, and extended the
sequester  by  one  year,  through  2030,  in  order  to  offset  the  added  expense  of  the  2020  cancellation.  The  2021  Consolidated  Appropriations  Act  was
subsequently signed into law on December 27, 2020 and extends the CARES Act suspension period to March 31, 2021.

Moreover,  there  has  been  heightened  governmental  scrutiny  over  the  manner  in  which  manufacturers  set  prices  for  their  marketed  products,  which  has
resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency
to  product  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reform  government  program  reimbursement
methodologies for drug products. DHHS, has solicited feedback on some of various measures intended to lower drug prices and reduce the out of pocket
costs of drugs and implemented others under its existing authority. For example, in May 2019, DHHS issued a final rule to allow Medicare Advantage
plans the option to use step therapy for Part B drugs beginning January 1, 2020. This final rule codified a DHHS policy change that was effective January
1,  2019.  As  part  of  the  Trump  Administration’s  so-called  “Blueprint”  to  lower  drug  prices,  DHHS  and  FDA  also  released  on  July  31,  2019  their  Safe
Importation Action Plan proposing two different pathways for the importation of foreign drug products. One pathway focuses on the importation of certain
drugs  from  Canada,  which  required  the  agencies  to  go  through  notice-and-comment  rulemaking,  while  the  second  pathway  allows  manufacturers  to
distribute their drugs manufactured abroad and was released as agency policy in an FDA guidance document first issued in December 2019. FDA’s notice
of proposed rulemaking to implement a system whereby state governmental entities could lawfully import and distribute prescription drugs sourced from
Canada  was  published  at  the  end  of  December  2019  and  in  September  2020,  the  rulemaking  was  finalized  by  FDA.  Those  new  regulations  became
effective  on  November  30,  2020,  although  the  impact  of  such  future  programs  is  uncertain,  in  part  because  lawsuits  have  been  filed  challenging  the
government’s authority to promulgate them. The final regulations may also be vulnerable to being overturned by a joint resolution of disapproval from
Congress under the procedures set forth in the Congressional Review Act, which could be applied to regulatory actions taken by the Trump Administration
on or after August 21, 2020 (i.e., in the last 60 days of legislative session of the 116th Congress). Congress and the executive branch have each indicated
that  it  will  continue  to  seek  new  legislative  and/or  administrative  measures  to  control  drug  costs,  making  this  area  subject  to  ongoing  uncertainty.  In
addition, the probability of success of other policies enacted over the final months of the Trump Administration and their impact on the U.S. prescription
drug  marketplace  is  unknown.  There  are  likely  to  be  political  and  legal  challenges  associated  with  implementing  these  reforms  as  they  are  currently
envisioned, and the January 20, 2021 transition to a new Democrat-led presidential administration created further uncertainty. Following his inauguration,
President Biden took immediate steps to order a regulatory freeze on all pending substantive executive actions in order to permit incoming department and
agency heads to review whether questions of fact, policy, and law may be implicated and to determine how to proceed.

Individual states in the United States have also increasingly passed legislation and implemented regulations designed to control pharmaceutical product
pricing,  including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and
transparency  measures,  and,  in  some  cases,  designed  to  encourage  importation  from  other  countries  and  bulk  purchasing.  In  December  2020,  the  U.S.
Supreme  Court  held  unanimously  that  federal  law  does  not  preempt  the  states’  ability  to  regulate  pharmaceutical  benefit  managers  (PBMs)  and  other
members of the health care and pharmaceutical supply chain, an important decision that may lead to further and more aggressive efforts by states in this
area.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action,
either in the United States or abroad. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which
could limit the amounts that federal and state governments will pay for healthcare products and services, including COSELA and any future products for
which we secure marketing approval.

Human Capital

As  of  December  31,  2021,  we  had  148  full-time  employees,  including  58  in  research  and  development  and  90  in  selling,  general  and  administrative
functions. Of these full-time employees, 33 had an MD, PhD or PharmD. We have no collective bargaining agreements with our employees, and we have
not  experienced  any  work  stoppages.  We  expect  headcount  growth  to  continue  for  the  foreseeable  future,  particularly  as  we  continue  to  develop  our
products and commercialize COSELA. We consider our relations with our employees to be good.

Diversity and Inclusion

Diversity  and  inclusion  are  an  important  part  of  our  culture.  We  seek  to  build  a  diverse  and  inclusive  workplace  where  we  can  leverage  our  collective
cognitive and other diversity. We conduct routine pay equity analysis to determine we have pay equity across gender and race in similar jobs, accounting
for factors such as role, experience, education and level. We also have a Culture Committee comprised of employees across departments, who focus on
employee engagement and other initiatives throughout the year.

32

Compensation and Benefits

We offer competitive compensation to attract and retain the best people. Our total compensation package includes market-competitive salary, bonuses, and
equity. We offer full-time employees equity at the time of hire and through annual equity grants because we want them to consider themselves to have an
ownership  stake  in  the  company  and  to  be  committed  to  our  long-term  success.  We  offer  a  wide  range  of  benefits  across  areas  such  as  health,  family,
finance, community, and time off, including healthcare and wellness benefits, a 401(k) plan, access to legal services, family leave, and paid time off.

Protection and Support of our Employees During the COVID-19 Pandemic

In response to the COVID-19 pandemic, we put in place the following safety measures for our employees, patients, healthcare professionals, and suppliers
to limit exposure and protect the health of those we employ and serve. These measures included, but were not limited to, we substantially restricted travel,
supplied personal protective equipment to employees, limited access to our headquarters and asked most of our staff to work remotely. On short notice, we
transitioned most of our employees to working remotely and added bandwidth and VPN capacity to our infrastructure. In addition, we continued to enhance
our  cybersecurity  protections.  As  a  company,  we  supported  our  employees  by  maintaining  base  compensation  throughout  the  year,  and  our  year-end
practices  around  merit,  bonus  and  equity  were  not  impacted.  We  continue  to  build  a  strong  supportive  culture  around  values  of  patients  first,  integrity,
respect and collaboration. Our efforts to develop our culture will last far beyond this pandemic.

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of
the  other  information  in  this  Annual  Report,  including  our  financial  statements  and  related  notes,  before  investing  in  our  common  stock.  The  risks  and
uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not
material,  may  also  become  important  factors  that  affect  us.  If  any  of  the  following  risks  occur,  our  business,  operating  results  and  prospects  could  be
materially harmed. In that event, the price of our common stock could decline, and you could lose part or all of your investment.

Summary Risk Factors

Below is a summary of the principal risk factors in each risk category that could adversely affect our business, operations, and financial results.

Risks related to the commercialization of COSELA

COSELA may fail to achieve the degree of market acceptance for commercial success.

COSELA may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies.

• We depend almost entirely on the commercial success of COSELA.
•
• We may not be able to effectively sell or market our COSELA, or generate substantial product revenues.
•
• We face substantial competition.
• We must comply with post-approval development and regulatory requirements to maintain FDA approval of COSELA.
•
•
•

Product liability lawsuits against us could cause us to incur substantial liabilities.
If we violate the guidelines pertaining to promotion and advertising we may be subject to disciplinary action.
Our relationships with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws
and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and
future earnings.

Risks related to development of COSELA:

If we are unable to successfully develop and commercialize COSELA, our business will be materially harmed.
Delays in the enrollment of patients in clinical trials, may delay or prevent our plans.
Initial success in our ongoing clinical trials may not be indicative of results obtained when these trials are completed.

•
•
•
• We  may  incur  additional  costs  or  experience  delays  in  completing  the  development  and  may  ultimately  be  unable  to  obtain  the  approval

COSELA in additional indications.

Risks related to our financial position and need for additional capital:

• We may need additional funding.
• We expect to incur losses for the foreseeable future and may never achieve or maintain profitability.
•
•

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights.
Our limited operating history may make it difficult for you to evaluate the success of our business.

Risks related to marketing approval of COSELA:

•

•

•

If  we  are  not  able  to  obtain,  or  if  there  are  delays  in  obtaining,  the  additional  required  marketing  approvals,  we  will  not  be  able  to  broadly
commercialize COSELA, and our ability to generate revenue will be materially impaired.
COSELA  may  cause  undesirable  side  effects  that  could  delay  or  prevent  its  marketing  approval,  limit  the  commercial  profile  of  an  approved
label, or result in significant negative consequences following marketing approval, if any.
COSELA is subject to extensive post-marketing regulatory requirements and could be subject to post-marketing restrictions or withdrawal from
the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with
COSELA.

Risks related to employee matters, managing growth and other risks related to our business

• We currently have a limited number of employees, and our future success depends on our ability to retain key executives and to attract, retain and

motivate qualified personnel.

• We  face  risks  related  to  health  epidemics  and  outbreaks,  including  the  novel  coronavirus  (COVID-19),  which  could  significantly  disrupt  our

preclinical studies and clinical trials.

• We expect to potentially implement sales, marketing and distribution capabilities, and as a result, we may encounter difficulties in managing our

growth, which could disrupt our operations.

Risks related to our dependence on third parties

• We rely on, and expect to continue to rely on, third parties to conduct our clinical trials for COSELA. If these third parties do not successfully
carry  out  their  contractual  duties,  comply  with  regulatory  requirements  or  meet  expected  deadlines,  we  may  not  be  able  to  obtain  marketing
approval for or commercialize COSELA, and our business could be substantially harmed.

• We contract with third parties for the manufacture of COSELA for preclinical studies and clinical trials and commercialization. This reliance on
third parties increases the risk that we will not have sufficient quantities of COSELA or drugs or such quantities at an acceptable cost, which
could delay, prevent or impair our development or commercialization efforts.

• We rely on, and expect to continue to rely on, third parties for the supply of COSELA.  If these third parties do not successfully carry out their

contractual duties or meet expected deadlines, we may not be able to fulfill orders of COSELA and our business could be substantially harmed.

Risks related to our intellectual property

•

If  we  are  unable  to  obtain  and  maintain  intellectual  property  protection  for  our  technology  and  products,  or  if  the  scope  of  the  intellectual
property protection obtained is not sufficiently broad, our competitors could commercialize technology and products similar or identical to ours,
and our ability to successfully commercialize our technology and products may be impaired and, if we infringe the valid patent rights of others,
we may be prevented from making, using or selling our products or may be subject to damages or penalties.

• We may become involved in administrative adversarial proceedings in the U.S. PTO or in the patent offices of foreign countries brought by a
third party to attempt to cancel or invalidate our patent rights, which could be expensive, time consuming and cause a loss of patent rights.
• We may have to file one or more lawsuits in court to prevent a third party from selling a product or using a product in a manner that infringes our

patent, which could be expensive, time consuming and unsuccessful, and ultimately result in the loss of our proprietary market.

Risks related to our common stock

•
•

The price of our common stock may be volatile and fluctuate substantially.
Provisions in our corporate charter documents and under Delaware law could make an acquisition of our company, which may be beneficial to
our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

For a more complete discussion of the material risks facing our business, see below.

Risks related to the commercialization of COSELA

We depend almost entirely on the commercial success of COSELA. There is no assurance that our commercialization efforts in the U.S. with respect to
COSELA will be successful or that we will be able to generate revenues at the levels or within the timing we expect or at the levels or within the timing
necessary to support our goals.

To  date,  we  have  generated  $11.1  million  in  revenues  from  the  sale  of  COSELA.  COSELA  was  approved  by  the  FDA  in  February  2021  and  was
commercially available in the U.S. on March 2, 2021. There is no assurance that the sales of COSELA will grow on the timing we anticipate. We may
encounter delays or hurdles related to our sales efforts that affect amount of revenue generated and the timing of such revenue.

Our business currently depends heavily on our ability to successfully commercialize COSELA in the U.S. to treat patients with ES-SCLC. We may never
be  able  to  successfully  commercialize  COSELA  or  meet  our  expectations  with  respect  to  revenues.  We  have  never  marketed,  sold  or  distributed  for
commercial  use  any  pharmaceutical  product  prior  to  COSELA.  There  is  no  guarantee  that  the  infrastructure,  systems,  processes,  policies,  personnel,
relationships and materials we have built in anticipation of the commercialization of COSELA in the U.S. will be sufficient for us to achieve success at the
levels  we  expect.  Additionally,  healthcare  providers  may  not  accept  a  new  treatment  paradigm  for  patients  with  ES-SCLC.  We  may  also  encounter
challenges related to reimbursement of COSELA, even as we have had positive early indications from payors, including potential limitations in the scope,
breadth, availability, or amount of reimbursement covering COSLEA. Similarly, healthcare settings or patients may determine that the financial burdens of
treatment are not acceptable. Our results may also be negatively impacted if we have not adequately sized our field teams or our physician segmentation
and targeting strategy is inadequate or if we encounter deficiencies or inefficiencies in our infrastructure or processes. Any of these issues could impair our
ability  to  successfully  commercialize  COSELA  or  to  generate  substantial  revenues  or  profits  or  to  meet  our  expectations  with  respect  to  the  amount  or
timing  of  revenue  or  profits.  Any  issues  or  hurdles  related  to  our  commercialization  efforts  may  materially  adversely  affect  our  business,  results  of
operations, financial condition and prospects. There is no guarantee that we will be successful in our commercialization efforts with respect to COSELA.

Our COSELA commercialization efforts may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in
the medical community necessary for commercial success.

Our COSELA commercialization efforts may fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical
community.  If  COSELA  does  not  achieve  an  adequate  level  of  acceptance,  we  may  not  generate  significant  product  revenues  and  we  may  not  become
profitable. The degree of market acceptance of COSELA and will depend on a number of factors, including:

•
•
•
•
•
•
•
•
•
•
•
•
•

•

the timing of our receipt of any additional marketing approvals;
the terms of any approvals and the countries in which approvals are obtained;
the efficacy and safety and potential advantages and disadvantages compared to alternative treatments;
the prevalence and severity of any side effects associated with our products;
the additional indications for which our products are approved;
adverse publicity about our products or favorable publicity about competing products;
the approval of other products for the same indications as our products;
our ability to offer our products for sale at competitive prices;
the convenience and ease of administration compared to alternative treatments;
the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;
the success of our physician education programs;
the strength of our marketing and distribution support;
the availability of third-party coverage and adequate reimbursement, including patient cost-sharing programs such as copays and deductibles;
and
any restrictions on the use of our products together with other medications.

If COSELA fails to achieve market acceptance, it could have a material and adverse effect on our business, financial condition, results of operation and
prospects.

If we are unable to establish effective sales or marketing capabilities or enter into agreements with third parties to sell or market COSELA, we may not
be able to effectively sell or market COSELA, if approved, or generate substantial product revenues.

To achieve commercial success for COSELA, we must build our sales, marketing, managerial, and other non-technical capabilities or make arrangements
with  third  parties  to  perform  these  services.  There  are  risks  involved  with  both  establishing  our  own  sales  and  marketing  capabilities  and  entering  into
arrangements with third parties to perform these services.

36

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Factors that may inhibit our efforts to commercialize COSELA on our own include:

•
•
•

•

our inability to recruit and retain adequate numbers of effective sales and marketing personnel;
the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe any future drugs;
the lack of complementary drugs to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with
more extensive product lines; and
unforeseen costs and expenses associated with creating an independent sales and marketing organization.

In addition, we may not be successful in entering into arrangements with third parties to market and distribute COSELA or may be unable to do so when
needed or on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary
resources and attention to market and distribute our products effectively. If we do not establish sales, marketing, and distribution capabilities successfully,
either on our own or in collaboration with third parties, we will not be successful in commercializing COSELA to receive marketing approval or any such
commercialization may experience delays or limitations. If we are not successful in commercializing COSELA, either on our own or through collaborations
with one or more third parties, our business, results of operations, financial condition and prospects will be materially adversely affected.

Even if we are able to commercialize COSELA, it may become subject to unfavorable pricing regulations or third-party coverage and reimbursement
policies, which would harm our business.

The regulations that govern marketing approvals, pricing and reimbursement for new drugs vary widely from country to country. Some countries require
approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing approval is granted. In
some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a
result, we might obtain marketing approval for COSELA in a particular country, but then be subject to price regulations that delay our commercial launch,
possibly for lengthy time periods, and negatively impact the revenues we are able to generate from the sale of COSELA in that country. Adverse pricing
limitations may hinder our ability to recoup our investment in COSELA, even if marketing approval is obtained.

Our ability to commercialize COSELA successfully also will depend in part on the extent to which coverage and reimbursement for COSELA and related
treatments will be available from government authorities, private health insurers and other organizations. In the United States, the principal decisions about
reimbursement for new medicines are typically made by the CMS, an agency within the U.S. Department of Health and Human Services, as CMS decides
whether and to what extent a new medicine will be covered and reimbursed under Medicare. Private payors tend to follow CMS to a substantial degree. It is
difficult to predict what CMS will decide with respect to reimbursement. Reimbursement agencies in Europe may be more conservative than CMS. For
example,  a  number  of  cancer  drugs  are  generally  covered  and  paid  for  in  the  United  States,  but  have  not  been  approved  for  reimbursement  in  certain
European countries. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have
attempted to control costs by limiting coverage and the amount of payments for particular drugs. Increasingly, third-party payors are requiring that drug
companies provide them with predetermined discounts from list prices and are challenging the prices charged for drugs. We cannot be sure that coverage
will be available for COSELA and, if coverage is available, the level of payments. Reimbursement may impact the demand for, or the price of, COSELA. If
reimbursement is not available or is available only to limited levels, we may not be able to successfully commercialize COSELA.

In  addition  to  CMS  and  private  payors,  professional  organizations  such  as  the  National  Comprehensive  Cancer  Network  and  the  American  Society  of
Clinical Oncology can influence decisions about reimbursement for medicines by determining standards of care. In addition, many private payors contract
with commercial vendors who sell software that provide guidelines that attempt to limit utilization of, and therefore reimbursement for, certain products
deemed to provide limited benefit to existing alternatives. Such organizations may set guidelines that limit reimbursement or utilization of our products.

There may be significant delays in obtaining reimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the
drug is approved by the FDA or similar regulatory authorities outside the United States. Moreover, eligibility for reimbursement does not imply that any
drug  will  be  paid  for  in  all  cases  or  at  a  rate  that  covers  our  costs,  including  research,  development,  manufacture,  sale  and  distribution.  Interim
reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may
vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and
may  be  incorporated  into  existing  payments  for  other  services.  Net  prices  for  drugs  may  be  reduced  by  mandatory  discounts  or  rebates  required  by
government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they
may be sold at lower prices than in the United States. Our inability to promptly obtain coverage and profitable payment rates from both government-funded
and private payors for any approved drugs that we develop could have a material adverse effect on our operating results, our ability to raise capital needed
to commercialize drugs and our overall financial condition.

37

 
 
 
 
 
If market opportunities for COSELA are smaller than we estimate or if any FDA approval that we receive for additional indications for COSELA are
based on a narrower definition of the patient population, our revenues may be substantially lower than we estimate.

We are focused on the development and commercialization of COSELA, the first and only therapy indicated to proactively help protect bone marrow from
the damage of chemotherapy. We have estimated the number of people who have cancer or will develop cancer and have estimated those who could benefit
from COSELA. However, our estimates, which have been developed from a number of sources, may ultimately be inaccurate. Our estimates may change
because of novel studies, the number of potential patients may be fewer than contemplated, the additional indications for COSELA approved by FDA may
be based on a narrower definition of the patient population than we have estimated, patients may not be receptive to treatment with COSELA, patients may
select our competitors’ products instead of ours, or it may be more difficult to identify the potential patient population than anticipated, all of which could
cause the market opportunities for COSELA to be more limited than we predicted and adversely impact our business and profitability.

We  face  substantial  competition,  which  may  result  in  others  discovering,  developing  or  commercializing  competing  products  before  or  more
successfully than we do.

The  development  and  commercialization  of  new  drug  products  is  highly  competitive.  We  face  competition  with  respect  to  COSELA  from  major
pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and
biotechnology companies that currently market and sell products or are pursuing the development of products for the treatment of the disease indications
for which we are developing COSELA. Some of these competitive products and therapies are based on scientific approaches that are the same as or similar
to our approach, and others are based on entirely different approaches. Potential competitors also include academic institutions, government agencies and
other  public  and  private  research  organizations  that  conduct  research,  seek  patent  protection  and  establish  collaborative  arrangements  for  research,
development, manufacturing and commercialization.

Specifically,  there  are  a  large  number  of  companies  developing  or  marketing  treatments  for  cancer,  including  many  major  pharmaceutical  and
biotechnology companies. COSELA competes with (a) existing growth factor support treatments, and (b)  multiple approved drugs or drugs that may be
approved in the future for indications for which we may develop COSELA.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have
fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA
or other marketing approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a
strong market position before we are able to enter the market and/or slow our marketing approval. Some of the important competitive factors affecting the
success of all COSELA are likely to be their efficacy, safety, convenience, price and the availability of reimbursement from government and other third-
party payors.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and
expertise  in  research  and  development,  manufacturing,  preclinical  studies,  conducting  clinical  trials,  obtaining  marketing  approvals  and  marketing
approved  products  than  we  do.  Mergers  and  acquisitions  in  the  pharmaceutical  and  biotechnology  industries  may  result  in  even  more  resources  being
concentrated among a smaller number of our competitors. Smaller and early-stage companies may also prove to be significant competitors, particularly
through  collaborative  arrangements  with  large  and  established  companies.  These  third  parties  compete  with  us  in  recruiting  and  retaining  qualified
scientific  and  management  personnel,  establishing  clinical  trial  sites  and  patient  registration  for  clinical  trials,  as  well  as  in  acquiring  technologies
complementary to, or necessary for, our programs.

Because COSELA received approval by the FDA, we must still comply with post-approval development and regulatory requirements to maintain that
approval and, if we fail to do so, FDA could withdraw its approval of COSELA, which would lead to substantially lower revenues.

For drugs granted approval, the FDA typically requires post-marketing confirmatory trials to evaluate the anticipated effect on irreversible morbidity or
mortality or other clinical benefit. These confirmatory trials must be completed with due diligence. As a condition of the accelerated approval of COSELA,
we  are  required  to  (i)  conduct  a  study  in  a  sufficient  number  of  adult  patients  with  extensive  stage-small  cell  lung  cancer  undergoing  chemotherapy  to
evaluate  the  impact  of  COSELA  on  disease  progression  or  survival  in  patients  with  chemotherapy-induced  myelosuppression  treated  with  a
platinum/etoposide-containing regimen or topotecan-containing regimen with at least 2 years of follow-up (ii) conduct an in vitro metabolism study and
CYP phenotyping study at clinically relevant concentrations to appropriately determine major metabolic pathway for COSELA. Characterize the formation
of  the  major  circulating  metabolite  of  trilaciclib,  M8,  using  the  purified  M8  compound  with  a  validated  bioanalytical  method),  (iii) conduct  an  in  vitro
Drug-Drug Interaction (DDI) study to evaluate the major circulating metabolite of COSELA, M8, as an inhibitor for major

38

 
 
 
 
CYP enzymes and drug transporters, and (iv) conduct a clinical trial to evaluate the effect of hepatic impairment on the pharmacokinetics and safety of
COSELA.

The FDA may withdraw approval of COSELA if, for example, the trial required to verify the predicted clinical benefit fails to verify such benefit or does
not  demonstrate  sufficient  clinical  benefit  to  justify  the  risks  associated  with  COSELA.  The  FDA  may  also  withdraw  approval  if  other  evidence
demonstrates that COSELA is not shown to be safe or effective under the conditions of use, we fail to conduct any required post approval trial of COSELA
with due diligence or we disseminate false or misleading promotional materials relating thereto.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products that we may develop.

We face an inherent risk of product liability exposure related to the evaluation of COSELA in human clinical trials and will face an even greater risk if we
commercially  sell  any  products  that  we  may  develop.  If  we  cannot  successfully  defend  ourselves  against  claims  that  COSELA  caused  injuries,  we  will
incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

decreased demand for COSELA or products that we may develop;
injury to our reputation and significant negative media attention;

•
•
• withdrawal of clinical trial participants;
•
•
•
•
•

significant costs to defend the related litigation;
substantial monetary awards to trial participants or patients;
loss of revenue;
reduced resources of our management to pursue our business strategy; and
the inability to successfully commercialize any products that we may develop.

We  currently  hold  $10.0  million  in  product  liability  insurance  coverage  in  the  aggregate,  with  a  per  incident  limit  of  $10.0  million,  which  may  not  be
adequate to cover all liabilities that we may incur. We may need to increase our insurance coverage as we expand our clinical trials. Insurance coverage is
increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may
arise.

If we or any of our current or future partners violate the guidelines pertaining to promotion and advertising of COSELA, we or they may be subject to
disciplinary action by the FDA's Office of Prescription Drug Promotion (OPDP) or other regulatory authorities.

The FDA’s Office of Prescription Drug Promotion (OPDP), is responsible for reviewing prescription drug advertising and promotional labeling to ensure
that  the  information  contained  in  these  materials  is  not  false  or  misleading.  There  are  specific  disclosure  requirements,  and  the  applicable  regulations
mandate that advertisements cannot be false or misleading or omit material facts about the product. Prescription drug promotional materials must present a
fair  balance  between  the  drug’s  effectiveness  and  the  risks  associated  with  its  use.  Most  warning  letters  from  OPDP  cite  inadequate  disclosure  of  risk
information.

OPDP  prioritizes  its  actions  based  on  the  degree  of  risk  to  the  public  health,  and  often  focuses  on  newly  introduced  drugs  and  those  associated  with
significant health risks. There are two types of letters that OPDP typically sends to companies that violate its drug advertising and promotional guidelines:
untitled letters and warning letters. In the case of an untitled letter, OPDP typically alerts the drug company of the violation and issues a directive to refrain
from future violations, but does not typically demand other corrective action. A warning letter is typically issued in cases that are more serious or where the
company is a repeat offender. Although we have not received any such letters from OPDP, we or any of our current or future partners may inadvertently
violate OPDP’s guidelines in the future and be subject to an OPDP untitled letter or warning letter, which may have a negative impact on our business.

39

 
 
 
 
 
 
 
 
 
 
Our  relationships  with  customers  and  third-party  payors  are  subject  to  applicable  anti-kickback,  fraud  and  abuse  and  other  healthcare  laws  and
regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future
earnings.

As  we  are  commercializing  COSELA,  we  are  subject  to  additional  healthcare  statutory  and  regulatory  requirements  and  enforcement  by  federal
government and the states and foreign governments in the jurisdictions in which we conduct our business. Healthcare providers, physicians and third-party
payors play a primary role in the recommendation and prescription of COSELA. Our arrangements with third-party payors and customers expose us to
broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations  that  constrain  the  business  or  financial  arrangements  and  relationships
through  which  we  market,  sell  and  distribute  any  products  for  which  we  obtain  marketing  approval.  Restrictions  under  applicable  federal  and  state
healthcare laws and regulations include the following:

•

•

•

•

the  federal  Anti-Kickback  Statute  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,  offering,  receiving  or
paying 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 or recommendation of, any good or service, for which payment may be made under a federal healthcare program such as
Medicare and Medicaid; a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to
have committed a violation;
the  federal  false  claims  laws  impose  criminal  and  civil  penalties,  including  civil  whistleblower  or  qui  tam  actions,  against  individuals  or
entities for knowingly presenting, or causing to be presented, to the federal government, 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; in addition, the government
may  assert  that  a  claim  including  items  and  services  resulting  from  a  violation  of  the  federal  Anti-Kickback  Statute  constitutes  a  false  or
fraudulent claim for purposes of the False Claims Act;
the  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  imposes  criminal  and  civil  liability  for  executing  a
scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making
any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services; similar to the federal
Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have
committed a violation;
the  federal  physician  payment  transparency  requirements,  sometimes  referred  to  as  the  “Sunshine  Act”  under  the  Patient  Protection  and
Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education  Reconciliation  Act  of  2010,  or  collectively  the  ACA,  require
manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health
Insurance Program to report to the Centers for Medicare & Medicaid Services, or CMS, information related to payments and other transfers
of value to physicians and teaching hospitals and the ownership and investment interests of physicians and their immediate family members
in such manufacturers;

•

• HIPPA, as amended by the Health Information Technology for Economic and Clinical Health Act and its implementing regulations, which
also imposes obligations on certain covered entity healthcare providers, health plans, and healthcare clearinghouses as well as their business
associates that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory
contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;
analogous  state  and  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false  claims  laws,  may  apply  to  sales  or  marketing
arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-governmental  third-party  payors,  including  private
insurers;
some  state  laws  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the
relevant compliance guidance promulgated by the federal government and may require drug manufacturers to report information related to
payments and other transfers of value to physicians and other healthcare providers or marketing expenditures; and
state and foreign laws also govern 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.

•

•

Efforts to ensure that our business arrangements with third parties comply with applicable healthcare laws and regulations involve substantial costs. It is
possible that governmental authorities may conclude that our business practices may not comply with current or future statutes, regulations or case law
involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any
other  governmental  regulations  that  may  apply  to  us,  we  may  be  subject  to  significant  civil,  criminal  and  administrative  penalties,  damages,  fines,
imprisonment, exclusion of products from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of
our operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with
applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

40

 
 
 
 
 
 
 
 
Governments outside the United States tend to impose strict price controls, which may adversely affect our revenues, if any.

In some countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to governmental control. In these
countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain
reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-effectiveness of COSELA to
other  available  therapies.  If  reimbursement  of  COSELA  is  unavailable  or  limited  in  scope  or  amount,  or  if  pricing  is  set  at  unsatisfactory  levels,  our
business could be harmed, possibly materially.

Risks related to development of COSELA

If we are unable to successfully commercialize additional indications for COSELA or experience significant delays in doing so, our business will be
materially harmed.

We have invested substantially all of our efforts and financial resources identifying and developing our COSELA. Our ability to generate product revenues
will  depend  on  the  successful  development  and  commercialization  of  COSELA.  COSELA  will  require  additional  development,  management  of
development  and  manufacturing  activities,  marketing  approval  in  multiple  jurisdictions,  obtaining  manufacturing  supply,  commercialization  activities,
substantial investment and significant marketing efforts.

We have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and
rapidly evolving fields, particularly in the biopharmaceutical area. For example, to execute our business plan, we will need to successfully:

•
•
•
•
•
•

•
•

build and maintain robust sales, distribution and marketing capabilities, either on our own or in collaboration with strategic partners;
gain acceptance for COSELA by patients, the medical community and third-party payors;
compete effectively with other therapies;
execute development activities for COSLEA, including successful enrollment in and completion of clinical trials;
obtain required marketing approvals for the development and commercialization of additional indications for COSELA;
obtain and maintain patent and trade secret protection and regulatory exclusivity for COSELA and ensure that we do not infringe the valid
patent rights of third parties;
protect, leverage and expand our intellectual property portfolio;
establish and maintain clinical and commercial manufacturing capabilities or make arrangements with third-party manufacturers for clinical
and commercial manufacturing;
obtain and maintain healthcare coverage and adequate reimbursement;

•
• maintain a continued acceptable safety profile for COSELA ;
•
•
• manage  our  spending  as  costs  and  expenses  increase  due  to  preclinical  development,  clinical  trials,  marketing  approvals  and

develop and maintain any strategic relationships;
enforce and defend intellectual property rights and claims; and

commercialization.

If  we  do  not  achieve  one  or  more  of  these  factors  in  a  timely  manner  or  at  all,  we  could  experience  significant  delays  or  an  inability  to  successfully
commercialize COSELA, which would materially harm our business.

If  we  experience  delays  or  difficulties  in  the  enrollment  of  patients  in  clinical  trials,  development  of  COSELA  may  be  delayed  or  prevented,  which
would have a material adverse effect on our business.

Identifying and qualifying patients to participate in clinical trials for COSELA is critical to our success. In particular, because we are initially focused on
patients with diseases with genetically defined tumors, our ability to enroll eligible patients may be limited or may result in slower enrollment than we
anticipate.  We  may  not  be  able  to  initiate  or  continue  clinical  trials  for  COSELA  if  we  are  unable  to  locate  and  enroll  a  sufficient  number  of  eligible
patients to participate in these trials. Patient enrollment may be affected by many factors including:

•
•
•
•
•
•
•

the severity of the disease under investigation;
the eligibility criteria for the clinical trial in question;
the perceived risks and benefits of COSELA under study;
the efforts to facilitate timely enrollment in clinical trials;
the patient referral practices of physicians;
the availability of competing therapies and clinical trials; and
the proximity and availability of clinical trial sites for prospective patients.

41

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If  we  experience  delays  or  difficulties  in  the  enrollment  of  patients  in  clinical  trials,  our  clinical  trials  may  be  delayed  or  terminated.  Any  delays  in
completing our clinical trials will increase our costs, delay or prevent development of COSELA and the approval process, and jeopardize our ability to
commence product sales and generate revenue. Any of these occurrences may harm our business, financial condition and prospects significantly.

Initial success in our ongoing clinical trials may not be indicative of results obtained when these trials are completed or in later stage trials.

We are currently evaluating COSELA in clinical trials. There can be no assurance that any of our clinical trials will ultimately be successful or support
further clinical development of COSELA. There is a high failure rate for drugs and biologics proceeding through clinical trials. A number of companies in
the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical development even after achieving promising results in earlier
studies, and any such setbacks in our clinical development could have a material adverse effect on our business and operating results.

We may not be able to identify additional therapeutic indications for COSELA or to expand our portfolio of product candidates.

We are conducting a number of clinical trials to identify new therapeutic indications for COSELA and to expand our portfolio of product candidates.
However, we may be unsuccessful in developing additional therapeutic indications for COSELA. For example, our initial research in colorectal cancer,
breast cancer, and bladder cancer may have shown potential for therapeutic opportunities yet our clinical trials in these possible additional therapeutic
indications may ultimately fail. Moreover, such clinical trials require the use of significant financial, human, and technical resources. Even if we are able to
identify new opportunities, COSELA will not be commercially available in these indications for a number of years due to extensive clinical testing
requirements and regulatory approvals. Additionally, we may focus our limited efforts and resources on a new therapeutic indication that is ultimately
unsuccessful. Therefore, we cannot guarantee that we will ever be able to identify and develop additional therapeutic indications for COSELA or expand
our portfolio of product candidates, which could adversely impact our future growth and prospects.

Clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in
completing,  or  ultimately  be  unable  to  complete,  the  development  and  may  experience  delays  in  obtaining,  or  ultimately  be  unable  to  obtain,  the
approval of COSELA in additional indications.

The  risk  of  failure  in  drug  development  is  high.  Before  obtaining  marketing  approval  from  regulatory  authorities  for  the  sale  of  COSELA,  we  must
complete preclinical development and conduct extensive clinical trials to demonstrate the safety and efficacy of COSELA in humans. Clinical trials are
expensive, difficult to design and implement and can take several years to complete, and their outcomes are inherently uncertain. Failure can occur at any
time during the clinical trial process. Further, the results of preclinical studies and early clinical trials of COSELA may not be predictive of the results of
later-stage  clinical  trials,  and  interim  results  of  a  clinical  trial  do  not  necessarily  predict  final  results.  Moreover,  preclinical  and  clinical  data  are  often
susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical
studies and clinical trials have nonetheless failed to obtain marketing approval of their products.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval
in additional indications or commercialize COSELA. Clinical trials may be delayed, suspended or prematurely terminated because costs are greater than we
anticipate or for a variety of reasons, such as:

•

•

•

•

•
•
•

•

•

delay  or  failure  in  reaching  agreement  with  the  FDA  or  a  comparable  foreign  regulatory  authority  on  a  trial  design  that  we  are  able  to
execute;
delay  or  failure  in  obtaining  authorization  to  commence  a  trial  or  inability  to  comply  with  conditions  imposed  by  a  regulatory  authority
regarding the scope or design of a clinical trial;
delays  in  reaching,  or  failure  to  reach,  agreement  on  acceptable  terms  with  prospective  trial  sites  and  prospective  contract  research
organizations, or CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and
trial sites;
inability, delay, or failure in identifying and maintaining a sufficient number of trial sites, many of which may already be engaged in other
clinical programs;
delay or failure in recruiting and enrolling suitable subjects to participate in a trial;
delay or failure in having subjects complete a trial or return for post-treatment follow-up;
clinical sites and investigators deviating from the clinical protocol, failing to conduct the trial in accordance with regulatory requirements, or
dropping out of a trial;
failure to initiate or delay of or failure to complete a clinical trial as a result of an IND being placed on clinical hold by the FDA, or for other
reasons;
lack of adequate funding to continue a clinical trial, including unforeseen costs due to enrollment delays, requirements to conduct additional
clinical trials and increased expenses associated with the services of our CROs and other third parties;

•

•

clinical  trials  of  COSELA  may  produce  negative  or  inconclusive  results,  and  we  may  decide,  or  regulators  may  require  us,  to  conduct
additional clinical trials or abandon product development programs;
the number of patients required for clinical trials of COESLA may be larger than we anticipate, enrollment in these clinical trials may be
slower than we anticipate, or participants may drop out of these clinical trials at a higher rate than we anticipate;
our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or
at all;
regulators, or a Data Safety Monitoring Board, or DSMB, if one is used for our clinical trials, may require that we suspend or terminate our
clinical  trials  for  various  reasons,  including  noncompliance  with  regulatory  requirements,  unforeseen  safety  issues  or  adverse  side  effects,
failure to demonstrate a benefit from using a drug, or a finding that the participants are being exposed to unacceptable health risks;
the supply or quality of COSELA or other materials necessary to conduct clinical trials may be insufficient;
the FDA or other regulatory authorities may require us to submit additional data or impose other requirements before permitting us to initiate
a clinical trial; or
there may be changes in governmental regulations or administrative actions.

Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of marketing
approval for COSELA in additional indications. Further, the FDA may disagree with our clinical trial design and our interpretation of data from clinical
trials or may change the requirements for approval even after it has reviewed and commented on the design for our clinical trials.

If  we  are  required  to  conduct  additional  clinical  trials  or  other  studies  of  COSELA  beyond  those  that  we  currently  contemplate,  if  we  are  unable  to
successfully complete clinical trials of COSELA or other studies, if the results of these trials or tests are not positive or are only modestly positive or if
there are safety concerns, we may:

•
•
•

•
•

be delayed in obtaining marketing approval for COSELA in additional indications;
obtain approval for indications or patient populations that are not as broad as intended or desired;
obtain  approval  with  labeling  that  includes  significant  use  or  distribution  restrictions  or  safety  warnings  that  would  reduce  the  potential
market for our products or inhibit our ability to successfully commercialize our products;
be subject to additional post-marketing restrictions and/or requirements; or
have the product removed from the market after obtaining marketing approval.

Our  product  development  costs  will  also  increase  if  we  experience  delays  in  preclinical  and  clinical  development  or  receiving  the  requisite  marketing
approvals. We do not know whether any of our preclinical studies or clinical trials will need to be restructured or will be completed on schedule, or at all.
Significant preclinical or clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize COSELA or
allow our competitors to bring products to market before we do and impair our ability to successfully commercialize COSELA and may harm our business
and results of operations.

Our  development  of  COSELA,  a  CDK4/6  inhibitor  to  decrease  the  incidence  of  chemotherapy-induced  myelosuppression,  is  novel,  unproven  and
rapidly evolving.

COSELA  is  a  short-acting  intravenous  CDK4/6  inhibitor.  The  use  of  a  CDK4/6  inhibitor  to  decrease  the  incidence  of  chemotherapy-induced
myelosuppression is a novel approach and we believe that we are the only company currently developing a CDK4/6 inhibitor for this patient population.
Even  though  COSELA  has  demonstrated  positive  results  in  clinical  trials  for  small  cell  lung  cancer,  we  may  not  succeed  in  demonstrating  safety  and
efficacy of COSELA in additional indications.

Advancing COSELA creates significant challenges for us, including:

•

•

•

obtaining marketing approval for multiple indications, as the FDA and other regulatory authorities have limited experience with commercial
development of a CDK4/6 inhibitor for this type of use;
educating medical personnel regarding the potential safety benefits, as well as the challenges, of incorporating our product candidates into
their treatment regimens; and
establishing sales and marketing capabilities to gain market acceptance of a novel therapy.

Risks related to our financial position and need for additional capital

We will need substantial additional funding. If we are unable to raise capital when needed, we would be compelled to delay, reduce or eliminate our
product development programs or commercialization efforts.

The development of pharmaceutical drugs is a capital-intensive venture. We expect our expenses to continue to increase along with our ongoing activities,
particularly  as  we  support  commercial  activities  and  conduct  larger-scale  clinical  trials  of,  and  seek  marketing  approval  for,  COSELA  in  additional
indications.  For  example,  we  expect  to  incur  significant  COSELA  commercialization  expenses  related  to  product  sales,  marketing,  manufacturing  and
distribution. We may also need to raise additional funds sooner if we choose to pursue additional indications and/or geographies for COSELA or otherwise
expand  more  rapidly  than  we  presently  anticipate.  Furthermore,  we  have  incurred,  and  expect  to  continue  to  incur,  additional  costs  associated  with
operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are
unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our clinical programs, development efforts or
any future commercialization efforts.

As of December 31, 2021, we had $221.2 million in cash and cash equivalents. We believe that, based upon our current operating plan, our existing capital
resources  will  be  sufficient  to  fund  our  anticipated  operations  for  greater  than  12  months  from  the  date  of  filing  this  Annual  Report.  Our  future  capital
requirements  and  the  period  for  which  we  expect  our  existing  resources  to  support  our  operations  may  vary  significantly  from  what  we  expect.  Our
monthly spending levels vary based on new and ongoing commercialization expenses, research and development, and other corporate activities. Because
the length of time and activities associated with successful commercialization and research and development of COSELA is highly uncertain, we are unable
to estimate the actual funds we will require for commercialization and development of COSELA. In addition, our future capital requirements will depend
on many factors, and could increase significantly as a result of many factors, including:

•

•
•
•
•

•
•

•

•
•
•

the  costs  of  commercialization  activities,  including  product  sales,  marketing,  manufacturing  and  distribution  of  COSELA  for  which  we
receive marketing approval;
the scope, progress, results and costs of development, laboratory testing and clinical trials for COSELA;
the scope, prioritization and number of our research and development programs;
the costs, timing and outcome of regulatory review of COSELA;
the extent to which we enter into non-exclusive, jointly funded clinical research collaboration arrangements, if any, for the development of
COSELA in combination with other companies’ products;
our ability to establish collaboration arrangements for the development of COSELA on favorable terms, if at all;
the achievement of milestones or occurrence of other developments that trigger payments under our license agreement and any collaboration
agreements into which we may enter, if any;
the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical trial costs under future collaboration agreements,
if any;
the extent to which we acquire or in-license product candidates and technologies, and the terms of such in-licenses;
revenue received from commercial sales of COSELA and any future product candidates; and
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending
intellectual property-related claims.

Conducting studies and clinical trials is a time-consuming, expensive and uncertain process that can take years to complete, and we may never generate the
necessary  data  or  results  required  to  obtain  marketing  approval  and  achieve  product  sales.  In  addition,  COSELA  and  our  future  product  candidates,  if
approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that may not be commercially
available for some time, if ever. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives.

Any  additional  fundraising  efforts  may  divert  our  management  from  their  day-to-day  activities,  which  may  adversely  affect  our  ability  to  develop  and
commercialize COSELA and future product candidates. Volatility in the financial markets have generally made equity and debt financing more difficult to
obtain and may have a material adverse effect on our ability to meet our fundraising needs. We cannot guarantee that future financing will be available in
sufficient  amounts  or  on  terms  acceptable  to  us,  if  at  all.  Moreover,  the  terms  of  any  financing  may  adversely  affect  the  holdings  or  the  rights  of  our
stockholders and the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our
shares to decline.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue the commercialization of COSELA or
any one or more of our research or development programs or be unable to expand our operations or otherwise capitalize on our business opportunities, as
desired, which could materially affect our business, financial condition and results of operations.

44

 
 
 
 
 
 
 
 
 
 
 
 
We  have  incurred  significant  operating  losses  since  our  inception.  We  expect  to  incur  losses  for  the  foreseeable  future  and  may  never  achieve  or
maintain profitability.

We have incurred significant operating losses since our inception. We incurred net losses of $148.4 million for the year ended December 31, 2021, $99.3
million  for  the  year  ended  December  31,  2020,  and  $122.4  million  for  the  year  ended  December  31,  2019.  As  of  December  31,  2021,  we  had  an
accumulated deficit of $584.5 million. It may be several years, if ever, before we become profitable. To date, we have financed our operations through sales
of our preferred and common stock, license agreements and debt. We expect to continue to incur significant expenses and increasing operating losses for
the  foreseeable  future.  The  net  losses  we  incur  may  fluctuate  significantly  from  quarter  to  quarter.  We  anticipate  that  our  expenses  will  increase
substantially as we:

•
•
•
•

•
•
•
•
•
•

•

continue development of trilaciclib, including initiation of additional clinical trials
identify and develop new product candidates;
seek additional marketing approvals for trilaciclib upon successful completion of clinical trials;
grow  our  sales,  marketing  and  distribution  infrastructure  to  commercialize  COSELA  and  any  future  products  for  which  we  may  obtain
marketing approval;
achieve market acceptance of our product candidates in the medical community and with third-party payors;
maintain, expand and protect our intellectual property portfolio;
hire additional personnel;
enter into collaboration arrangements, if any, for the development of our product candidates or in-license other products and technologies;
identify and develop new product candidates;
add operational, financial and management information systems and personnel, including personnel to support our product development and
planned future commercialization efforts; and
continue to incur increased costs as a result of operating as a public company.

Because of the numerous risks and uncertainties associated with developing and commercializing pharmaceutical drugs, we are unable to predict the extent
of any future losses or when we will become profitable, if at all. In addition, our expenses could increase beyond expectations if we are required by the
FDA or foreign regulatory agencies, to perform studies and clinical trials in addition to those that we currently anticipate for COSELA, or if there are any
delays in our or our partners completing clinical trials or the development of any of our product candidates.

To become and remain profitable, we must develop and commercialize products with significant market potential. This will require us to be successful in a
range of challenging activities, including the following:

•
•
•

completing clinical trials of COSELA that meet their clinical endpoints;
manufacturing, marketing and selling those products for which we may obtain marketing approval; and
achieving market acceptance of COSELA in the medical community and with third-party payors.

We may never succeed in these activities and, even if we do, may never generate revenues that are significant or large enough to achieve profitability. If we
do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable
would decrease the value of the company and could impair our ability to raise capital, maintain our discovery and preclinical development efforts, expand
our business or continue our operations and may require us to raise additional capital that may dilute your ownership interest. A decline in the value of our
company could also cause you to lose all or part of your investment.

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

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity financings,
debt financings, collaborations, strategic alliances and licensing arrangements. The sale of additional equity or convertible debt securities would dilute all
of  our  stockholders.  The  incurrence  of  indebtedness  would  result  in  increased  fixed  payment  obligations,  and  we  may  be  required  to  agree  to  certain
restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property
rights, limitations on declaring dividends and other operating restrictions that could adversely impact our ability to conduct our business. We could also be
required to seek funds through collaborations, strategic alliances or licensing arrangements with third parties, and we could be required to do so at an earlier
stage than otherwise would be desirable. In connection with any such collaborations, strategic alliances or licensing arrangements, we may be required to
relinquish valuable rights to our intellectual property, future revenue streams, research programs or product , grant rights to develop and market product
that we would otherwise prefer to develop and market ourselves, or otherwise agree to terms unfavorable to us, any of which may have a material adverse
effect on our business, operating results and prospects.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

Biopharmaceutical drug development is a highly speculative undertaking and involves a substantial degree of risk. Our operations to date have been limited
to  organizing  and  staffing  our  company,  business  planning,  raising  capital,  developing  our  technology,  identifying  potential  products,  undertaking
preclinical  studies,  and  conducting  clinical  trials  of  trilaciclib.  We  have  not  yet  demonstrated  our  ability  to  successfully  complete  large-scale,  pivotal
clinical  trials,  manufacture  a  commercial  scale  product,  or  arrange  for  a  third  party  to  do  so  on  our  behalf,  or  conduct  sales  and  marketing  activities
necessary for successful product commercialization. Typically, it takes several years to develop one new drug from the time it is discovered to when it is
available for treating patients. In addition, as a new business, we may encounter unforeseen expenses, difficulties, complications, delays and other known
and  unknown  factors.  We  will  need  to  transition  from  a  company  with  a  research  focus  to  a  company  capable  of  supporting  commercial  activities  and
continuing to develop products. We may not be successful in such a transition.

Our level of indebtedness and debt service obligations could adversely affect our financial condition and may make it more difficult for us to fund our
operations.

We have entered into a Second Amendment to the Loan and Security Agreement with Hercules Capital, Inc. for up to $150.0 million of debt under a term
loan. The maturity date of the Hercules Loan Agreement is November 1, 2026.  As of December 31, 2021, the Company has borrowed $75.0 million under
the Hercules Loan Agreement. The Company’s obligations under the Hercules Loan Agreement are secured by a blanket lien on substantially all of the
Company’s assets, including a security interest in the intellectual property.

This indebtedness may create additional financing risk for us, particularly if our business or prevailing financial market conditions are not conducive to
paying off or refinancing our outstanding debt obligations at maturity. This indebtedness could also have important negative consequences, including the
fact that we will need to repay our indebtedness by making payments of interest and principal, which will reduce the amount of money available to finance
our operations, our commercialization efforts, our research and development efforts and other general corporate activities.

If we were to become unable to pay, when due, the principal of, interest on, or other amounts due in respect of, our indebtedness, our financial condition
would be adversely affected.  Further, under the Hercules Loan Agreement, we are subject to certain restrictive covenants that, among other things, subject
to exceptions, restrict the Company’s ability to do the following things: declare dividends or redeem or repurchase equity interests; incur additional liens;
make loans and investments; incur additional indebtedness; engage in mergers, acquisitions, and asset sales; transact with affiliates; undergo a change in
control; and add or change business locations. If we breach any of these restrictive covenants or are unable to pay our indebtedness under the Hercules
Loan Agreement when due, this could result in a default under the Hercules Loan Agreement. In such event, Hercules may elect (after the expiration of any
applicable notice or grace periods) to declare all outstanding borrowings, together with accrued and unpaid interest and other amounts payable under the
Hercules Loan Agreement, to be immediately due and payable. Any such occurrence would have an adverse impact on our financial condition.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could
harm our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use,
storage,  treatment  and  disposal  of  hazardous  materials  and  wastes.  Our  operations  involve  the  use  of  hazardous  and  flammable  materials,  including
chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these
materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from
our use of hazardous materials, we could be held liable for any resulting damages, and the amount of the liability could exceed our resources. We also
could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from
the  use  of  hazardous  materials,  this  insurance  may  not  provide  adequate  coverage  against  other  potential  liabilities.  We  do  not  maintain  insurance  for
environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive
materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or
future laws and regulations may impair our discovery, preclinical development or production efforts. Our failure to comply with these laws and regulations
also may result in substantial fines, penalties or other sanctions.

46

 
Our ability to use our net operating loss carryforwards and other tax attributes may be limited, and changes in tax laws could adversely impact our
business and financial position.

The  Internal  Revenue  Service  or  other  tax  authority  may  review  and  adjust  our  net  operating  loss  and  tax  credit  carryforwards  pursuant  to  the  Internal
Revenue Code of 1986 (the “Code”). In the event of an “ownership change” under Section 382 of the Code (“Section 382”), we may be subject to annual
limitations on our ability to utilize net operating loss and tax credit carryforwards. An ownership change constitutes a change in the ownership interest of
significant shareholders in excess of 50 percent on a cumulative basis over a three-year period. In April 2019, the Company completed an evaluation study
as to whether an “ownership change” had occurred and determined that the limitation would be approximately $8.0 million on federal net operating loss
carryforwards,  $1.2  million  on  state  net  operating  loss  carryforwards,  and  $0.1  million  on  R&D  tax  credit  carryforwards.  The  carryforward  amounts
reported above have already been reduced for these limitations. The Company continues to maintain a valuation allowance on the remaining NOLs as it
believes that it is more likely than not that all of the deferred tax asset associated with the NOLs will not be realized regardless of whether an “ownership
change” has occurred. As of December 31, 2021, our federal and state net operating loss carryforwards amounted to $510.0 million and $332.7 million,
respectively. Other changes in the ownership of our stock may have caused an ownership change in the past or could cause one in the future. Additional
ownership changes under Section 382 could further limit our ability to reduce future tax liabilities by utilizing our net operating loss carryforwards.

In addition, our capacity to utilize our net operating loss carryforwards and other tax attributes could be limited due to statutory and regulatory changes. For
example, among other things, the Tax Cuts and Jobs Act of 2017 (the “TCJA”) comprehensively changed U.S. federal tax rates, permitted capital
expenditures to be expensed, and restricted tax deductions for net interest expense and net operating losses. The CARES Act of 2020 was enacted to restore
the ailing U.S. economy during the COVID-19 pandemic. Among other things, the CARES Act temporarily eased the TCJA’s restrictions on net interest
expense tax deductions and altered the payroll tax scheme. Congress may enact additional tax legislation, and we cannot predict how future amendments in
tax laws and regulations will impact our business and financial position.

Risks related to marketing approval of COSELA for additional indications

If  we  are  not  able  to  obtain,  or  if  there  are  delays  in  obtaining,  additional  required  marketing  approvals  for  COSELA,  we  will  not  be  able  to
commercialize it in other indications, and our ability to generate revenue will be materially impaired.

COSELA and the activities associated with its development and commercialization, including  design, testing, manufacture, safety, efficacy, recordkeeping,
labeling,  storage,  approval,  advertising,  promotion,  sale,  distribution,  import  and  export  are  subject  to  comprehensive  regulation  by  the  FDA  and  other
regulatory agencies in the United States and by comparable authorities in other countries. These requirements include submissions of safety and other post-
marketing  information  and  reports,  registration  and  listing  requirements,  current  good  manufacturing  practice,  or  cGMP,  requirements  relating  to
manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, including periodic inspections by FDA and other
regulatory  authorities,  requirements  regarding  the  distribution  of  samples  to  physicians  and  recordkeeping.  Before  we  can  commercialize  COSELA  in
additional indications, it must be approved by the FDA pursuant to a new drug application, or NDA, in the United States, by the European Medicines Agency,
or EMA, pursuant to a marketing authorization application, or MAA, in the European Union, and by similar regulatory authorities outside the United States
prior to commercialization.

The process of obtaining marketing approvals, both in the United States and abroad, is expensive and takes several years, if approval is obtained at all, and
can  vary  substantially  based  upon  a  variety  of  factors,  including  the  type,  complexity  and  novelty  of  the  product  candidates  involved.  Failure  to  obtain
marketing  approval  for  COSELA  in  additional  indications  will  prevent  us  from  commercializing  it  in  those  indications.  We  have  limited  experience  in
planning and conducting the clinical trials required for marketing approvals, and we expect to rely on third-party contract research organizations, or CROs,
to assist us in this process. Obtaining marketing approval requires the submission of extensive preclinical and clinical data and supporting information to
regulatory authorities for each therapeutic indication to establish product safety and efficacy. Securing marketing approval also requires the submission of
information about the product manufacturing process, and in many cases the inspection of manufacturing facilities by the regulatory authorities. COSELA
may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that
may  limit  commercial  use.  Regulatory  authorities  have  substantial  discretion  in  the  approval  process  and  may  refuse  to  accept  any  application  or  may
decide that our data are insufficient for approval and require additional preclinical studies or clinical trials. COSLEA may be delayed in receiving, or fail to
receive, marketing approval in additional indications for many reasons, including the following:

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;

•
• we  may  be  unable  to  demonstrate  to  the  satisfaction  of  the  FDA  or  comparable  foreign  regulatory  authorities  that  COSELA  is  safe  and

•

effective for its proposed indication;
the results of clinical trials may not meet the level of statistical significance required by the FDA or comparable foreign regulatory authorities
for approval;

47

 
 
 
 
 
 
• we may be unable to demonstrate that COSELA’s clinical and other benefits outweigh its safety risks;
•
•

the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;
the data collected from clinical trials of COSELA may not be sufficient to support the submission of an NDA or other submission to obtain
marketing approval in the United States or elsewhere;
third-party  manufacturers  or  our  clinical  or  commercial  product  may  be  unable  to  meet  the  FDA’s  cGMP  requirements  or  similar
requirements of foreign regulatory authorities; and
the  approval  requirements  or  policies  of  the  FDA  or  comparable  foreign  regulatory  authorities  may  significantly  change  in  a  manner
rendering our clinical data insufficient for approval.

•

•

In  addition,  even  if  we  were  to  obtain  approval  for  additional  indications,  regulatory  authorities,  may  grant  approval  contingent  on  the  performance  of
costly  post-marketing  clinical  trials,  or  may  approve  a  label  that  does  not  include  the  labeling  claims  necessary  or  desirable  for  the  successful
commercialization of COSELA. Any of the foregoing scenarios could materially harm the commercial prospects of COSELA.

If we experience delays in obtaining approval or if we fail to obtain approval of COSELA in additional indications, the commercial prospects for COSELA
may be harmed and our ability to generate revenues will be materially impaired.

Our  product  may  cause  undesirable  side  effects  that  could  delay  or  prevent  its  marketing  approval  for  additional  indications,  limit  its  commercial
profile, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product could cause us or the FDA or other regulatory authorities to interrupt, delay or halt our clinical trials for any
additional indiciations and could result in more restrictive labels or the delay or denial of marketing approval by the FDA or other regulatory authorities of
our product in additional indications. Results of our ongoing clinical trials could reveal a high and unacceptable severity and prevalence of these or other
side effects we may observe when trilaciclib is administered in the other tumor types and treatment combinations. 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  for  any  or  all  additional  indications.  In  addition  to  this,  the  drug-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.

Further, clinical trials by their nature utilize a sample of the potential patient population. With a limited number of patients, rare and severe side effects of
trilaciclib  may  only  be  uncovered  with  a  significantly  larger  number  of  patients  exposed  to  the  product.  If  our  product  receives  marketing  approval  in
additional indications and we or others identify undesirable side effects caused by such product (or any other similar drugs) after such approval, a number
of potentially significant negative consequences could result, including:

regulatory authorities may withdraw or limit their approval of such product;
regulatory authorities may require the addition of labeling statements, such as a “boxed” warning or a contraindication;

•
•
• we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;
• we may be required to change the way such product is distributed or administered, conduct additional clinical trials or change the labeling of

•

the product;
regulatory authorities may require a Risk Evaluation and Mitigation Strategy plan to mitigate risks, which could include medication guides,
physician  communication  plans,  or  elements  to  assure  safe  use,  such  as  restricted  distribution  methods,  patient  registries  and  other  risk
minimization tools;

• we may be subject to regulatory investigations and government enforcement actions;
• we may decide to remove the product from the marketplace after it is approved;
• we could be sued and held liable for injury caused to individuals exposed to or taking our product; and
•

our reputation may suffer.

We believe that any of these events could prevent us from achieving or maintaining market acceptance of COSELA in ES-SCLC and could substantially
increase the costs of gaining marketing approval for COSELA in additional indications and significantly impact our ability to successfully commercialize
COSELA and generate revenues in other tumor types and treatment combinations.

COSELA will be subject to extensive post-marketing regulatory requirements and could be subject to post-marketing restrictions or withdrawal from
the market, and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our
products, when approved.

Commercialization  activities  for  COSELA,  such  as  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

48

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
requirements. The FDA or a comparable foreign regulatory authority may also impose requirements for costly post-marketing preclinical studies or clinical
trials and surveillance to monitor the safety or efficacy of the product. The FDA closely regulates the post-approval marketing and promotion of drugs to
ensure drugs are marketed only for the approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent
restrictions  on  manufacturers’  communications  regarding  use  of  their  products,  and  if  we  promote  COSELA  or  any  other  of  our  products  beyond  their
approved indications, we may be subject to enforcement actions or prosecution arising from that off-label promotion. Violations of the Federal Food, Drug,
and Cosmetic Act relating to the promotion of prescription drugs may lead to investigations alleging violations of federal and state healthcare fraud and
abuse and other laws, as well as state consumer protection laws.

In  addition,  later  discovery  of  previously  unknown  adverse  events  or  other  problems  with  our  products,  manufacturers  or  manufacturing  processes,  or
failure to comply with regulatory requirements, may yield various results, including:

restrictions on such products, manufacturers or manufacturing processes;
restrictions on the labeling or marketing of a product;
restrictions on product distribution or use;
requirements to conduct post-marketing studies or clinical trials;

•
•
•
•
• warning or untitled letters;
• withdrawal of the products from the market;
•
•
•
•
•
•
•

refusal to approve pending applications or supplements to approved applications that we submit;
recall of products;
fines, restitution or disgorgement of profits or revenues;
suspension or withdrawal of marketing approvals;
refusal to permit the import or export of our products;
product seizure; or
injunctions or the imposition of civil or criminal penalties.

Non-compliance  with  European  Union  requirements  regarding  safety  monitoring  or  pharmacovigilance  can  also  result  in  significant  financial  penalties.
Similarly, failure to comply with the European Union’s requirements regarding the protection of personal information can also lead to significant penalties
and sanctions.

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

Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize COSELA and affect the
prices we may obtain.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the
healthcare  system  that  could  prevent  or  delay  marketing  approval  of  COSELA,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to
profitably sell COSELA.

In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, changed the way Medicare covers and
pays  for  pharmaceutical  products.  The  legislation  expanded  Medicare  coverage  for  drug  purchases  by  the  elderly  and  certain  disabled  people  and
introduced  a  reimbursement  methodology  based  on  average  sales  prices  for  physician-administered  drugs.  In  addition,  this  law  provided  authority  for
limiting the number of drugs that will be covered in any therapeutic class. Cost reduction initiatives and other provisions of this law and future laws could
decrease the coverage and price that we will receive for any approved products. While the MMA only applies to drug benefits for Medicare beneficiaries,
private  payors  often  follow  Medicare  coverage  policy  and  payment  limitations  in  setting  their  own  payment  rates.  Therefore,  any  limitations  in
reimbursement that results from the MMA may result in reductions in payments from private payors.

In  March  2010,  the  ACA  became  law.  The  ACA  is  a  sweeping  law  intended  to  broaden  access  to  health  insurance,  reduce  or  constrain  the  growth  of
healthcare  spending,  enhance  remedies  against  fraud  and  abuse,  add  new  transparency  requirements  for  the  healthcare  and  health  insurance  industries,
impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the ACA of importance to COSELA are the following:

•
•

an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologic products;
an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program;

49

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•
•
•
•
•
•

expansion of healthcare fraud and abuse laws, including the False Claims Act and the Anti-Kickback Statute, new government investigative
powers, and enhanced penalties for noncompliance;
a  new  Medicare  Part  D  coverage  gap  discount  program,  in  which  manufacturers  must  agree  to  offer  50%  point-of-sale  discounts  off
negotiated prices;
extension of manufacturers’ Medicaid rebate liability;
expansion of eligibility criteria for Medicaid programs;
expansion of the entities eligible for discounts under the Public Health Service Act’s pharmaceutical pricing program;
new requirements to report financial arrangements with physicians and teaching hospitals;
a new requirement to annually report drug samples that manufacturers and distributors provide to physicians; and
a  new  Patient-Centered  Outcomes  Research  Institute  to  oversee,  identify  priorities  in,  and  conduct  comparative  clinical  effectiveness
research, along with funding for such research.

There have been several recent U.S. congressional inquiries and proposed and enacted federal and state legislation designed to bring more transparency to
drug  pricing,  reduce  the  costs  of  drugs  under  Medicare,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reform
government  program  reimbursement  methodologies  for  drug  products.  Although  any  proposed  measures  will  require  authorization  through  additional
legislation  to  become  effective,  Congress  and  the  current  administration  have  each  indicated  that  it  will  continue  to  seek  new  legislative  and/or
administrative  measures  to  control  drug  costs.  Also,  the  FDA  recently  issued  draft  guidance  that  would  allow  manufacturers  to  import  their  own  FDA-
approved drugs that are authorized for sale in other countries as a means to lower drug prices.

We expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and
in  additional  downward  pressure  on  the  price  that  we  will  receive  for  any  approved  product.  Any  reduction  in  payments  from  Medicare  or  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.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical
products.  We  cannot  be  sure  whether  additional  legislative  changes  will  be  enacted,  or  whether  FDA  regulations,  guidance  or  interpretations  will  be
changed, or what the impact of such changes on the marketing approvals, if any, of our product candidates, may be. In addition, increased scrutiny by the
U.S.  Congress  of  the  FDA’s  approval  process  may  significantly  delay  or  prevent  marketing  approval,  as  well  as  subject  us  to  more  stringent  product
labeling and post-marketing conditions and other requirements.

The FDA and other government agencies could prevent the timely development and commercialization of COSELA due to concerns about the quality
of that data from clinical trials performed in China.

Numerous factors, including regulatory and policy changes, could impact the likelihood and timing of obtaining FDA approval of additional indications for
COSELA. The FDA has recently expressed reservations regarding the quality of data from clinical trials conducted in China for the development of cancer
treatments. In August 2020, we entered into a license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd. (“Simcere”), for the
development and commercialization of COSELA in Greater China.  In addition, we have collaborated with Simcere in China to help us develop additional
indications for COSELA. We are dependent on Simcere’s ability to comply with applicable foreign and U.S. regulatory requirements. The FDA may be
hesitant to approve drugs that include data from clinical trials performed in China. This may require us to modify our current clinical trials to exclude the
data from China or perform additional clinical trials without Simcere’s assistance, which could be expensive and time-consuming. A delay in obtaining the
required regulatory approvals could in turn lead to delays in the development of additional indications for COSELA, which could adversely affect us
financially.

Our future growth may depend, in part, on our ability to penetrate foreign markets, where we would be subject to additional regulatory burdens and
other risks and uncertainties.

Our future profitability may depend, in part, on our ability to commercialize our product in foreign markets. In order to market and sell our product in the
European Union and many other jurisdictions, we or our third-party collaborators must obtain separate marketing approvals and comply with numerous and
varying regulatory requirements. The approval procedure varies among countries and economic areas and can involve additional testing. The time required
to obtain approval may differ substantially from that required to obtain FDA approval. The marketing approval process outside the United States generally
includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it is required that the product be
approved for reimbursement before the product can be approved for sale in that country. We or these third parties may not obtain approvals from regulatory
authorities outside the United States on a timely basis, if at all. Approval by FDA does not ensure approval by regulatory authorities in other countries or
jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or
jurisdictions or by FDA. Additionally, a failure or delay in obtaining marketing approval in one jurisdiction may have a negative effect on the marketing
approval process in others. Approval procedures

50

 
 
 
 
 
 
 
 
 
 
 
vary  among  jurisdictions  and  can  involve  requirements  and  administrative  review  periods  different  from,  and  greater  than,  those  in  the  United  States,
including additional preclinical studies or clinical trials. Obtaining foreign marketing approvals and compliance with foreign regulatory requirements could
result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our product in certain countries. If we fail to comply
with the regulatory requirements in international markets and/or receive applicable marketing approvals, our target market will be reduced and our ability
to realize the full market potential of our product will be harmed.

We may not be able to file for marketing approvals and may not receive necessary approvals to commercialize our products in any market. If we obtain
approval of our product candidates and ultimately commercialize our product in foreign markets, we would be subject to additional risks and uncertainties,
including:

•
•
•
•
•
•
•
•
•
•
•

•

•
•
•

our customers’ ability to obtain reimbursement for our product in foreign markets;
our inability to directly control commercial activities because we are relying on third parties;
the burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements;
different medical practices and customs in foreign countries affecting acceptance in the marketplace;
import or export licensing requirements;
longer accounts receivable collection times;
longer lead times for shipping;
language barriers for technical training;
reduced or no protection on pharmaceutical products or their use in some foreign countries;
the unwillingness of courts in some foreign jurisdictions to enforce patents even when valid and infringed in that country;
the possibility of pre-grant or post-grant review proceedings in certain foreign countries that allow a petitioner to hold up patent rights for an
extended period or permanently by challenging the patent filing at the patent office of that country;
the possibility of a compulsory license issued by a foreign country that allows a third-party company or a government to manufacture, use or
sell our products with a government-set low royalty to us;
the existence of additional potentially relevant third-party intellectual property rights;
foreign currency exchange rate fluctuations; and
the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute.

Foreign sales of COSELA could also be adversely affected by the imposition of governmental controls, political and economic instability, trade restrictions
and changes in tariffs.

Risks related to employee matters, managing growth and other risks related to our business

We  currently  have  a  limited  number  of  employees,  and  our  future  success  depends  on  our  ability  to  retain  key  executives  and  to  attract,  retain  and
motivate qualified personnel.

We  are  a  clinical  development  company,  and,  as  of  December  31,  2021,  had  148  employees,  which  includes  seven  executive  officers.  We  are  highly
dependent on the commercialization, research and development, clinical, and business development expertise of our executive officers, as well as the other
principal members of our management, scientific and clinical team. Although we have entered into employment agreements with our executive officers,
each  of  them  may  terminate  their  employment  with  us  at  any  time.  We  do  not  maintain  “key  person”  insurance  for  any  of  our  executives  or  other
employees.  In  addition,  we  rely  on  consultants  and  advisors,  including  scientific  and  clinical  advisors,  to  assist  us  in  formulating  our  research  and
development  and  commercialization  strategy.  Our  consultants  and  advisors  may  be  employed  by  employers  other  than  us  and  may  have  commitments
under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality
personnel, our ability to pursue our growth strategy will be limited.

Recruiting  and  retaining  qualified  scientific,  clinical,  manufacturing,  sales  and  marketing  personnel  will  also  be  critical  to  our  success.  The  loss  of  the
services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives
and  seriously  harm  our  ability  to  successfully  implement  our  business  strategy.  Furthermore,  replacing  executive  officers  and  key  employees  may  be
difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience
required to successfully develop, obtain marketing approval of and commercialize products. Competition to hire from this limited pool is intense, and we
may  be  unable  to  hire,  train,  retain  or  motivate  these  key  personnel  on  acceptable  terms  given  the  competition  among  numerous  pharmaceutical  and
biotechnology  companies  for  similar  personnel.  We  also  experience  competition  for  the  hiring  of  scientific  and  clinical  personnel  from  universities  and
research institutions. Failure to succeed in clinical trials may make it more challenging to recruit and retain qualified scientific personnel. If we are unable
to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.

We face risks related to health epidemics and outbreaks, including the novel coronavirus (COVID-19), which could significantly disrupt our preclinical
studies and clinical trials.

51

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In December 2019, a novel strain of coronavirus (COVID-19) surfaced in Wuhan, China and in March 2020, in an effort to halt the outbreak of COVID-19,
the United States, along with many other countries, placed significant restrictions on travel and many businesses have announced extended closures which
could adversely impact our operations. The COVID-19 pandemic has continued to evolve, with new variants (such as the Omicron variant) emerging and
spreading more easily and quickly than other variants.  As such, the duration and the geographic impact of the business disruption and related financial
impact resulting from the COVID-19 pandemic cannot be reasonably estimated at this time and our business could be adversely impacted by the effects of
the COVID-19 pandemic.

The enrollment of patients in current and future clinical trials may be slower due to the outbreak of COVID-19. In addition, we rely on independent clinical
investigators, contract research organizations and other third-party service providers to assist us in managing, monitoring and otherwise carrying out our
nonclinical studies and clinical trials, and the outbreak may affect their ability to devote sufficient time and resources to our programs. We also rely on third
party suppliers and contract manufacturers to produce the drug product we utilize in our clinical trials. Although we do not anticipate significant supply
chain  delays  or  shortages  as  a  result  of  the  COVID-19  pandemic  at  this  time,  the  outbreak  may  cause  delays  in  delivery  of  APIs  and  drug  product.
Temporary  closure  of  our  facilities,  or  facilities  at  which  our  clinical  trials  or  nonclinical  studies  are  conducted,  or  restrictions  on  the  ability  of  our
employees,  clinicians  or  patients  enrolled  in  our  trials  to  travel  could  adversely  affect  our  operations  and  our  ability  to  conduct  and  complete  our
nonclinical studies and clinical trials. As a result of the foregoing factors, the expected timeline for data readouts of our clinical trials may be negatively
impacted, which would adversely affect our business.

The COVID-19 pandemic also presents a number of challenges for our commercial business, including, among others, the impact due to continued travel
limitations  and  government-mandated  work-from-home  or  shelter-in-place  orders,  potential  decreased  product  demand  due  to  reduced  numbers  of  in-
person  meetings  with  prescribers  and  patient  visits  with  physicians,  possible  delay  in  cancer  treatments  with  chemotherapy  as  well  as  increased
unemployment resulting in lower new prescriptions.

In addition, the FDA’s ability to engage in routine regulatory and oversight activities, such as the review and clearance or approval of new products, may be
affected by the COVID-19 pandemic. The FDA and other regulatory authorities may have slower response times or be under-resourced. If the global health
concerns  continue  to  disrupt  or  prevent  the  FDA  or  other  regulatory  authorities  from  conducting  their  regular  reviews,  inspections,  or  other  regulatory
activities,  it  could  significantly  impact  the  ability  of  the  FDA  or  other  regulatory  authorities  to  timely  review  and  process  our  marketing  applications,
clinical trial authorizations, or other regulatory submissions, which could have a material adverse effect on our business.

The full extent to which COVID-19 impacts our business will depend on future developments, including, but not limited to, the ultimate severity and scope
of the pandemic, the pace at which governmental and private travel restrictions and public concerns about public gatherings will ease, the rate at which
historically large increases in unemployment rates will decrease, if at all, and whether, and the speed with which the economy recovers, which are highly
uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions to treat or contain
COVID-19 and any variants thereof,  or to otherwise limit their impact.

Unfavorable global economic conditions could adversely affect our business, financial condition, or results of operations.

Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. The global financial
crisis at the end of the last decade caused extreme volatility and disruptions in the capital and credit markets. A severe or prolonged economic downturn,
such  as  that  global  financial  crisis,  could  result  in  a  variety  of  risks  to  our  business,  including  our  ability  to  raise  additional  capital  when  needed  on
acceptable terms, if at all. A weak or declining economy could also strain our suppliers, possibly resulting in supply disruption. Any of the foregoing could
harm our business, and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact
our business.

52

We may encounter difficulties in managing our growth, which could disrupt our operations.

To  manage  our  anticipated  expansion,  we  must  continue  to  implement  and  improve  our  managerial,  operational  and  financial  systems,  and  continue  to
recruit and train additional qualified personnel. Also, our management may need to divert a disproportionate amount of its attention away from its day-to-
day activities and devote a substantial amount of time to managing these growth activities. Due to our limited resources, we may not be able to effectively
manage the expansion of our operations or recruit and train additional qualified personnel. This may result in weaknesses in our infrastructure, give rise to
operational  mistakes,  loss  of  business  opportunities,  loss  of  employees  and  reduced  productivity  among  remaining  employees.  The  expansion  of  our
operations may lead to significant costs and may divert financial resources from other projects, such as the development of our product. If our management
is unable to effectively manage our expected expansion, our expenses may increase more than expected, our ability to generate or increase our revenue
could  be  reduced  and  we  may  not  be  able  to  implement  our  business  strategy.  Our  future  financial  performance  and  our  ability  to  commercialize  our
product, if approved, and compete effectively will depend, in part, on our ability to effectively manage the future expansion of our company.

Our business and operations could suffer in the event of system failures.

We utilize information technology systems and networks to process, transmit and store electronic information in connection with our business activities. As
use of digital technologies has increased, cyber incidents, including deliberate attacks and attempts to gain unauthorized access to computer systems and
networks, have increased in frequency and sophistication. These threats pose a risk to the security of our systems and networks and the confidentiality,
availability  and  integrity  of  our  data.  There  can  be  no  assurance  that  we  will  be  successful  in  preventing  cyber-attacks  or  successfully  mitigating  their
effects.

Despite the implementation of security measures, our internal computer systems and those of our third-party CROs and other contractors and consultants
are vulnerable to damage from cyber-attack, computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical
failures.  Furthermore,  we  have  little  or  no  control  over  the  security  measures  and  computer  systems  of  our  third-party  CROs  and  other  contractors  and
consultants.  While  we  have  not  experienced  any  such  system  failure,  accident,  or  security  breach  to  date,  if  such  an  event  were  to  occur  and  cause
interruptions in our operations, it could result in a material disruption of our programs. For example, the loss of clinical trial data for COSELA could result
in delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security
breach  results  in  a  loss  of  or  damage  to  our  data  or  applications  or  other  data  or  applications  relating  to  our  technology  or  product,  or  inappropriate
disclosure of confidential or proprietary information, we could incur liabilities and the further development of our COSELA could be delayed.

Our employees, principal investigators, CROs and consultants may engage in misconduct or other improper activities, including non-compliance with
regulatory standards and requirements and insider trading.

We are exposed to the risk that our employees, principal investigators, CROs and consultants may engage in fraudulent conduct or other illegal activity.
Misconduct  by  these  parties  could  include  intentional,  reckless  and/or  negligent  conduct  or  disclosure  of  unauthorized  activities  to  us  that  violate  the
regulations of the FDA and other regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such
authorities; healthcare fraud and abuse laws and regulations in the United States and abroad; or laws that require the reporting of financial information or
data accurately. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended
to  prevent  fraud,  misconduct,  kickbacks,  self-dealing  and  other  abusive  practices.  These  laws  and  regulations  may  restrict  or  prohibit  a  wide  range  of
pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to these
laws also involve the improper use of information obtained in the course of clinical trials or creating fraudulent data in our preclinical studies or clinical
trials,  which  could  result  in  regulatory  sanctions  and  cause  serious  harm  to  our  reputation.  We  have  adopted  a  code  of  conduct  applicable  to  all  of  our
employees, but it is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and
prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or
other actions or lawsuits stemming from a failure to comply with these laws or regulations. Additionally, we are subject to the risk that a person could
allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves
or  asserting  our  rights,  those  actions  could  have  a  significant  impact  on  our  business,  including  the  imposition  of  civil,  criminal  and  administrative
penalties,  damages,  monetary  fines,  possible  exclusion  from  participation  in  Medicare,  Medicaid  and  other  federal  healthcare  programs,  contractual
damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to
operate our business and our results of operations.

We may fail to capitalize on product candidates that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on a specific product. As a result, we may forgo or delay pursuit of opportunities
with other product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on
viable  commercial  products  or  profitable  market  opportunities.  Our  spending  on  current  and  future  research  and  development  programs  and  product
candidates for specific indications may not yield any commercially viable product candidates. If we do not accurately evaluate the commercial potential or
target  market  for  a  particular  product  candidate,  we  may  relinquish  valuable  rights  to  that  product  candidate  through  collaboration,  licensing  or  other
royalty  arrangements  in  cases  in  which  it  would  have  been  more  advantageous  for  us  to  retain  sole  development  and  commercialization  rights  to  such
product candidate.

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

Earthquakes, pandemics such as the COVID-19 (coronavirus), or other natural disasters could severely disrupt our operations and have a material adverse
effect on our business, results of operations, financial condition and prospects. If a natural disaster, power outage or other event occurred that prevented us
from  using  all  or  a  significant  portion  of  our  headquarters,  that  damaged  critical  infrastructure,  such  as  the  manufacturing  facilities  of  our  third-party
contract  manufacturers,  or  that  otherwise  disrupted  operations,  it  may  be  difficult  or,  in  certain  cases,  impossible  for  us  to  continue  our  business  for  a
substantial period of time. The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or
similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a
material adverse effect on our business.

We may acquire businesses or drugs, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.

We  may  acquire  additional  businesses  or  drugs,  form  strategic  alliances  or  create  joint  ventures  with  third  parties  that  we  believe  will  complement  or
augment our existing business. If we acquire businesses with promising markets or technologies, we may not be able to realize the benefit of acquiring such
businesses if we are unable to successfully integrate them with our existing operations and company culture. We may encounter numerous difficulties in
developing,  manufacturing  and  marketing  any  new  drugs  resulting  from  a  strategic  alliance  or  acquisition  that  delay  or  prevent  us  from  realizing  their
expected benefits or enhancing our business. We cannot assure you that, following any such acquisition, we will achieve the expected synergies to justify
the transaction.

Risks related to our dependence on third parties

We rely on, and expect to continue to rely on, third parties to conduct our clinical trials for COSELA. If these third parties do not successfully carry out
their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to commercialize our product or obtain
marketing approval for additional indications, and our business could be substantially harmed.

We do not have the ability to independently conduct clinical trials. We rely on medical institutions, clinical investigators, contract laboratories and other
third parties, such as CROs, to conduct or otherwise support clinical trials for COSELA. We expect to rely heavily on these parties for performance of
clinical  trials  for  our  product.  Nevertheless,  we  will  be  responsible  for  ensuring  that  each  of  our  clinical  trials  is  conducted  in  accordance  with  the
applicable protocol, legal and regulatory requirements and scientific standards.

We, our investigators, and our CROs will be required to comply with regulations, including good clinical practice, or GCP, and other related requirements
for conducting, monitoring, recording and reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate,
and that the trial patients are adequately informed of the potential risks of participating in clinical trials and their rights are protected. These regulations are
enforced by the FDA, the Competent Authorities of the Member States of the European Economic Area and comparable foreign regulatory authorities for
any drugs in clinical development. The FDA enforces GCPs through periodic inspections of clinical trial sponsors, principal investigators and trial sites. If
we, our investigators or our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be called into question and the
FDA  or  comparable  foreign  regulatory  authorities  may  require  us  to  perform  additional  clinical  trials  before  considering  our  marketing  applications  for
approval. We cannot assure you that, upon inspection, the FDA will determine that any of our future clinical trials will comply with GCPs.

In addition, our clinical trials must be conducted with product produced under cGMPs. Our failure or the failure of our investigators or CROs to comply
with these requirements may require us to repeat clinical trials, which would delay the marketing approval process and could also subject us to enforcement
action.  We  also  are  required  to  register  certain  clinical  trials  and  post  the  results  of  such  completed  clinical  trials  involving  our  product  for  which  we
receive marketing approval on a government-sponsored database, ClinicalTrials.gov, within certain timeframes. Failure to do so can result in fines, adverse
publicity and civil and criminal sanctions.

54

 
Although we intend to design the clinical trials for COSELA, CROs will administer all of the clinical trials. As a result, many important aspects of our
development programs, including their conduct and timing, will be outside of our direct control. Our reliance on third parties to conduct future clinical
trials will also result in less direct control over the management of data developed through clinical trials than would be the case if we were relying entirely
upon  our  own  staff.  Communicating  with  outside  parties  can  also  be  challenging,  potentially  leading  to  mistakes  as  well  as  difficulties  in  coordinating
activities. Outside parties may:

have staffing difficulties;
fail to comply with contractual obligations;
experience regulatory compliance issues;
undergo changes in priorities or become financially distressed;

•
•
•
•
• make errors in the design, management or retention of our data or data systems; and/or
•

form relationships with other entities, some of which may be our competitors.

These factors may materially adversely affect the willingness or ability of third parties to conduct our clinical trials and may subject us to unexpected cost
increases that are beyond our control. If the CROs do not perform clinical trials in a satisfactory manner, breach their obligations to us or fail to comply
with regulatory requirements, the development, marketing approval and commercialization of our product may be delayed, we may not be able to obtain
marketing approval and commercialize our product candidates, or our development program may be materially and irreversibly harmed. If we are unable to
rely on clinical data collected by our CROs, we could be required to repeat, extend the duration of, or increase the size of any clinical trials we conduct, and
this could significantly delay commercialization and require significantly greater expenditures.

If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs. If CROs do not
successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the
clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, any clinical
trials  such  CROs  are  associated  with  may  be  extended,  delayed  or  terminated,  and  we  may  not  be  able  to  obtain  marketing  approval  in  additional
indications or successfully commercialize COSELA. As a result, we believe that our financial results and the commercial prospects for COSELA in the
subject indication would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We contract with third parties for the manufacture of COSELA for preclinical studies, clinical trials, and commercial supply. This reliance on third
parties increases the risk that we will not have sufficient quantities of COSELA or such quantities at an acceptable cost, which could delay, prevent or
impair our development or commercialization efforts.

We do not currently own or operate, nor do we have any plans to establish in the future, any manufacturing facilities. We rely, and expect to continue to
rely,  on  third  parties  for  the  manufacture  of  COSELA  for  preclinical  studies,  clinical  trials,  and  commercial  supply  of  COSELA.  This  reliance  on  third
parties increases the risk that we will not have sufficient quantities of our product or drugs or such quantities at an acceptable cost or quality, which could
delay, prevent or impair our development or commercialization efforts.

The facilities used to manufacture COSELA (drug substance and drug product) must be approved by the FDA (and comparable foreign regulatory authority
depending  on  where  marketing  authorizations  are  filed)  before  marketing  authorizations  are  approved.    Often,  but  not  always,  these  inspections  are
triggered  by  marketing  authorization  submissions.  We  are  completely  dependent  on  our  contract  manufacturers  for  compliance  with  current  Good
Manufacturing  Practices  (cGMPs)  in  connection  with  the  manufacture  of  our  product.  If  our  contract  manufacturers  cannot  successfully  manufacture
material that conforms to our specifications and to the regulatory requirements of the FDA or comparable foreign regulatory authority, then we will not be
able to use the products produced at their manufacturing facilities. In addition, we have no control over the ability of our contract manufacturers to maintain
adequate quality control, quality assurance and qualified personnel. If the FDA or comparable foreign regulatory authority finds that these facilities do not
comply with cGMP, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain marketing
approval for or market COSELA. Further, our failure, or the failure of our third party manufacturers, to comply with these or other applicable regulations
could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals,
license revocation, seizures or recalls of product or drugs, if approved, operating restrictions and criminal prosecutions, any of which could significantly
and adversely affect our business and supplies of COSELA.

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

•
•
•
•

reliance on the third party for regulatory compliance and quality assurance;
the possible breach of the manufacturing agreement by the third party;
the possible misappropriation of our proprietary information, including our trade secrets and know-how; and
the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us.

COSELA  may  compete  with  other  product  candidates  and  approved  drugs  for  access  to  manufacturing  facilities.  There  are  a  limited  number  of
manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us.

55

 
 
 
 
 
 
 
 
 
 
Any performance failure on the part of our existing or future manufacturers could delay clinical development, marketing approval, or commercialization
efforts. If our current contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers. Although we believe that there
are several potential alternative manufacturers who could manufacture our product, we may incur added costs and delays in identifying and qualifying any
such replacements.

Our current and anticipated future dependence upon others for the manufacture of our product or drugs may adversely affect our future profit margins and
our ability to commercialize any drugs that receive marketing approval on a timely and competitive basis.

The third parties upon which we rely for the supply of the drug substance, and drug products are our sole sources of supply and have limited capacity,
and the loss of any of these suppliers could harm our business.

Some drug substances and drug products for our product are supplied to us from single source suppliers with limited capacity. Our ability to successfully
develop our product, and to ultimately supply our commercial drugs in quantities sufficient to meet the market demand, depends in part on our ability to
obtain the drug substances and drug products in accordance with cGMP requirements and in sufficient quantities for clinical trials and commercialization.  
It is possible that our suppliers of drug substance or drug product which are not dual-sourced could, for any reason, cease their operations.  

We do not know whether our suppliers will be able to meet our demand, either because of the nature of our agreements with those suppliers, our limited
experience with those suppliers or our relative importance as a customer to those suppliers. It may be difficult for us to assess their ability to timely meet
our demand in the future based on past performance. While our suppliers have generally met our demand for their products on a timely basis in the past,
they may subordinate our needs in the future to their other customers.

For  our  product,  we  intend  to  identify  and  qualify  additional  manufacturers  to  provide  drug  substances  and  drug  products.  Establishing  additional  or
replacement  suppliers  for  drug  substances  and  drug  products  for  our  product,  if  required,  may  not  be  accomplished  quickly.  If  we  are  able  to  find  a
replacement supplier, such replacement supplier would need to be qualified, or we may have to perform comparative studies comparing the drug product
from a new manufacturer to the product used in any completed clinical trials. All of this may require additional regulatory approval, which could result in
further delay. While we seek to maintain adequate inventory of drug substance and drug product for our product, any interruption or delay in the supply of
components or materials, or our inability to obtain such drug substance and drug product from alternate sources at acceptable prices in a timely manner
could impede, delay, limit, or prevent our development efforts, which could harm our business, results of operations, financial condition, and prospects.

We,  or  our  third-party  manufacturers,  may  be  unable  to  successfully  scale-up  manufacturing  of  COSELA  in  sufficient  quality  and  quantity,  which
would delay or prevent us from developing and commercializing COSELA.

In order to conduct large-scale clinical trials of COSELA, or successfully commercialize COSELA, we will need to manufacture them in large quantities.
We, or any of our manufacturing partners, may be unable to successfully increase the manufacturing capacity of COSELA in a timely or cost-effective
manner, or at all. In addition, quality issues may arise during scale-up activities. If we, or any manufacturing partners, are unable to successfully scale up
the manufacture COSELA in sufficient quality and quantity, the development, testing, and clinical trials of the product may be delayed or infeasible, and
regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which could significantly harm our business.

We have entered into license agreements for lerociclib, a license agreement for the development of COSELA in greater China, and intend to continue
to  use  third-party  collaborators  to  help  us  develop  and  commercialize  any  new  products,  and  our  ability  to  commercialize  such  products  could  be
impaired or delayed if these collaborations are unsuccessful.

Our drug development programs and the potential commercialization of COSELA will require substantial additional cash to fund expenses. We may decide
to collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization of COSELA or lerociclib.

We have entered into license agreements with third-parties, and may continue to selectively pursue strategic collaborations, for the development and
commercialization of our products.  For example, (i) in June 2020, we entered into a license agreement with Genor Biopharma Co. Inc., for the
development and commercialization of lerociclib in the Asia-Pacific region (excluding Japan); (ii) in July 2020, we and EQRx entered into license
agreement pursuant to which we have granted EQRx the exclusive rights to develop and commercialize lerociclib in the U.S., Europe, Japan and all other
global markets, excluding the Asia-Pacific region (except Japan); and (iii)in August 2020, we entered into a license agreement with Nanjing Simcere
Dongyuan Pharmaceutical Co., Ltd, for the development and commercialization of COSELA in Greater China.

In our third-party collaborations, we are dependent upon the success of the collaborators to perform their responsibilities with continued cooperation. Our
collaborators may not cooperate with us or perform their obligations under our agreements with them. We

56

 
cannot control the amount and timing of our collaborators’ resources that will be devoted to performing their responsibilities under our agreements with
them. Our collaborators may choose to pursue alternative therapies in preference to those being developed in collaboration with us. Development and
commercialization will be delayed if collaborators fail to conduct their responsibilities in a timely manner or in accordance with applicable regulatory
requirements or if they breach or terminate their collaboration agreements with us. Disputes with our collaborators could also impair our reputation or
result in development delays, decreased revenues, and litigation expenses.

We face significant competition in seeking additional appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend,
among  other  things,  upon  our  assessment  of  the  collaborator’s  resources  and  expertise,  the  terms  and  conditions  of  the  proposed  collaboration  and  the
proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by
the  FDA  or  similar  regulatory  authorities  outside  the  United  States,  the  potential  market  for  the  subject  product,  the  costs  and  complexities  of
manufacturing and delivering such product to patients, the potential of competing drugs and market conditions generally. The proposed collaborator may
also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration
could be more attractive than the one with us for our product. The terms of any collaborations or other arrangements that we may establish may not be
favorable to us.

We  may  also  be  restricted  under  existing  collaboration  agreements  from  entering  into  future  agreements  on  certain  terms  with  potential  collaborators.
Collaborations  are  complex  and  time-consuming  to  negotiate  and  document.  In  addition,  there  have  been  a  significant  number  of  recent  business
combinations  among  large  pharmaceutical  companies  that  have  resulted  in  a  reduced  number  of  potential  future  collaborators.  We  may  not  be  able  to
negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of the product
for which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential
commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization
activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to
obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further
develop COSELA or bring it to market and generate drug revenue.

In addition, any collaboration that we enter into may not be successful. The success of our collaboration arrangements will depend heavily on the efforts
and activities of our collaborators. Collaborators generally have significant discretion in determining the efforts and resources that they will apply to these
collaborations.  Any  such  collaboration  may  require  us  to  incur  non-recurring  or  other  charges,  increase  our  near-  and  long-term  expenditures  and  pose
significant  integration  or  implementation  challenges  or  disrupt  our  management  or  business.  These  transactions  would  entail  numerous  operational  and
financial  risks,  including  exposure  to  unknown  liabilities,  disruption  of  our  business  and  diversion  of  our  management’s  time  and  attention  in  order  to
manage  a  collaboration,  incurrence  of  substantial  debt  or  dilutive  issuances  of  equity  securities  to  pay  transaction  consideration  or  costs,  higher  than
expected collaboration or integration costs, write-down of assets or goodwill or impairment charges, increased amortization expenses and difficulty and
cost in facilitating the collaboration.

Lastly, disagreements between parties to a collaboration arrangement regarding clinical development and commercialization matters can lead to delays in
the  development  process  or  commercializing  a  product  and,  in  some  cases,  termination  of  the  collaboration  arrangement.  These  disagreements  can  be
difficult to resolve if neither of the parties has final decision-making authority. Collaborations with pharmaceutical or biotechnology companies and other
third parties often are terminated or allowed to expire by the other party. Any such termination or expiration would adversely affect us financially and could
harm our business reputation.

Risks related to our intellectual property

If we are unable to obtain and maintain intellectual property protection for our technology and products, or if the scope of the intellectual property
protection obtained is not sufficiently broad, our competitors could commercialize technology and products similar or identical to ours, and our ability
to successfully commercialize our technology and products may be impaired and, if we infringe the valid patent rights of others, we may be prevented
from making, using or selling our products or may be subject to damages or penalties.

Our  success  depends  in  large  part  on  our  ability  to  obtain  and  maintain  patents  in  the  United  States  and  other  countries  that  adequately  protect  our
proprietary technology and products. We seek to protect our proprietary position by filing patent applications in the United States and in foreign countries
that cover COSELA, lerociclib and rintodestrant and their uses, pharmaceutical formulations and dosages, and processes for the manufacture of them. Our
patent portfolio currently includes both patents and patent applications.

The patent prosecution process is expensive and time-consuming. We may not be able to file and prosecute all necessary or desirable patent applications at
a  reasonable  cost  or  in  a  timely  manner.  We  may  choose  not  to  seek  patent  protection  for  certain  innovations  and  may  choose  not  to  pursue  patent
protection  in  certain  jurisdictions.  Under  the  laws  of  certain  jurisdictions,  patents  or  other  intellectual  property  rights  may  be  unavailable  or  limited  in
scope. It is also possible that we will fail to identify patentable aspects of our research and development before it is too late to obtain patent protection.

57

We currently solely own or exclusively license our patents and patent applications and we have the right to control the prosecution of the in-licensed patent
applications. In the future, we may choose to in-license additional patents or patent applications from third parties that we conclude are useful or necessary
for our business goals. We may not have the right to control the preparation, filing, prosecution or maintenance of such patent applications. Therefore, if we
do license additional patents or patent applications in the future, these patents and applications may not be prosecuted and enforced in a manner consistent
with the best interests of our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in
recent years been the subject of much litigation. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent
applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we
cannot know with certainty whether we were the first to make the inventions claimed in our owned or licensed patents or pending patent applications, or
that we were the first to file for patent protection of such inventions. As a result, the issuance, scope, validity, enforceability and commercial value of our
patent  rights  are  highly  uncertain.  Our  pending  and  future  patent  applications  may  not  result  in  patents  being  issued  which  protect  our  technology  or
products, in whole or in part, or which effectively prevent others from commercializing competitive technologies and products. Changes in either the patent
laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent
protection.

Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or
defense of our issued patents. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-
Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and
may  also  affect  patent  litigation.  The  U.S.  Patent  and  Trademark  Office,  or  U.S.  PTO,  recently  developed  new  regulations  and  procedures  to  govern
administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and in particular, the first
to file provisions, became effective on March 16, 2013. The Leahy-Smith Act also created certain new administrative adversarial proceedings, discussed
below.  It  is  not  clear  what,  if  any,  impact  the  Leahy-Smith  Act  will  have  on  the  operation  of  our  business.  However,  the  Leahy-Smith  Act  and  its
implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our
issued patents, all of which could have a material adverse effect on our business and financial condition.

The U.S. Supreme Court has issued opinions in patent cases in the last few years that many consider may weaken patent protection in the United States,
either  by  narrowing  the  scope  of  patent  protection  available  in  certain  circumstances,  holding  that  certain  kinds  of  innovations  are  not  patentable  or
generally otherwise making it easier to invalidate patents in court. Additionally, there have been recent proposals for additional changes to the patent laws
of the United States and other countries that, if adopted, could impact our ability to obtain patent protection for our proprietary technology or our ability to
enforce our proprietary technology. Depending on future actions by the U.S. Congress, the U.S. courts, the U.S. PTO and the relevant law-making bodies in
other countries, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to
enforce our existing patents and patents that we might obtain in the future.

Even if our patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from
competing with us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our owned or licensed patents by
developing similar or alternative technologies or products in a non-infringing manner.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged in
the courts or patent offices in the United States and in other countries. Such challenges may result in loss of exclusivity or in patent claims being narrowed,
invalidated  or  held  unenforceable,  in  whole  or  in  part,  which  could  limit  our  ability  to  stop  others  from  using  or  commercializing  similar  or  identical
technology  and  products,  or  limit  the  duration  of  the  patent  protection  of  our  technology  and  products.  Given  the  amount  of  time  required  for  the
development,  testing  and  regulatory  review  of  new  product  candidates,  patents  protecting  such  candidates  might  expire  before  or  shortly  after  such
candidates  are  commercialized.  As  a  result,  our  owned  and  licensed  patent  portfolio  may  not  provide  us  with  sufficient  rights  to  exclude  others  from
commercializing products similar or identical to ours. Likewise, a court could uphold and enforce a third-party patent that it rules we have infringed, which
would subject us to damages or prevent us from making, using or selling our products.

During patent prosecution in the United States and in most foreign countries, a third party can submit prior art or arguments to the reviewing patent office
to  attempt  to  prevent  the  issuance  of  a  competitor’s  patent.  For  example,  our  pending  patent  applications  may  be  subject  to  a  third-party  pre-issuance
submission of prior art to the U.S. PTO or an Observation in Europe. Such submission may convince the receiving patent office not to issue the patent. In
addition, if the breadth or strength of protection provided by our patents and patent applications is reduced by such third-party submission, it could affect
the value of our resulting patent or dissuade companies from collaborating with us to license, develop or commercialize current or future products.

The risks described here pertaining to our patents and other intellectual property rights also apply to any intellectual property rights that we may license in
the future, and any failure to obtain, maintain and enforce these rights could have a material adverse effect on

58

our business. In some cases, we may not have control over the prosecution, maintenance or enforcement of the patents that we license, and our licensors
may fail to take the steps that we believe are necessary or desirable in order to obtain, maintain and enforce the licensed patents. Any inability on our part
to adequately protect or defend our intellectual property may have a material adverse effect on our business, operating results and financial position.

We may become involved in administrative adversarial proceedings in the U.S. PTO or in the patent offices of foreign countries brought by a third party
to attempt to cancel or invalidate our patent rights, which could be expensive, time consuming and cause a loss of patent rights.

The  Leahy-Smith  Act  created  for  the  first  time  new  procedures  to  challenge  issued  patents  in  the  United  States,  including  post-grant  review  and  inter
partes review proceedings, which some third parties have been using to cause the cancellation of selected or all claims of issued patents of competitors. For
a patent with a priority date of March 16, 2013 or later, a petition for post-grant review can be filed by a third party in a nine-month window from issuance
of the patent. A petition for inter partes review can be filed immediately following the issuance of a patent if the patent was filed prior to March 16, 2013.
A petition for inter partes review can be filed after the nine-month period for filing a post-grant review petition has expired for a patent with a priority date
of March 16, 2013 or later. Post-grant review proceedings can be brought on any ground of challenge, whereas inter partes review proceedings can only be
brought  to  raise  a  challenge  based  on  published  prior  art.  These  administrative  adversarial  actions  at  the  U.S.  PTO  review  patent  claims  without  the
presumption of validity afforded to U.S. patents in lawsuits in U.S. federal courts, use a lower burden of proof than used by U.S. federal courts. The U.S.
PTO issued a Final Rule on November 11, 2018, announcing that it will now use the same claim construction currently used in the U.S. federal courts to
interpret patent claims, which is the plain and ordinary meaning of words used. If any of our patents are challenged by a third party in such a U.S. patent
office proceeding, there is no guarantee that we will be successful in defending the patent, which would result in a loss of the challenged patent right to us.
Further, even if a U.S. federal court or PTAB rules that a patent owned by us is valid and enforceable, if the other venue takes a contrary position, the patent
is considered invalid and not enforceable. Therefore, a party seeking to invalidate a patent owned by us in the United States has the procedural advantage of
two alternative venues.

Opposition or invalidation procedures are also available in most foreign countries. Many foreign authorities, such as the authorities at the European Patent
Office, have only post-grant opposition proceedings, however, certain countries, such as India, have both pre-grant and post-grant opposition proceedings.
These procedures have been used frequently against pharmaceutical patents in foreign countries. For example, in some foreign countries, these procedures
are  used  by  generic  companies  to  hold  up  an  innovator’s  patent  rights  as  a  means  to  allow  the  generic  company  to  enter  the  market.  This  activity  is
particularly prevalent in India, China and South America and may become more prevalent in Africa and other parts of Asia as certain countries reach more
established economies. If any of our patents are challenged in a foreign opposition or invalidation proceeding, we could face significant costs to defend our
patents, and we may not be successful. Uncertainties resulting from the initiation, continuation or loss of such proceedings could have a material adverse
effect on our ability to compete in the market place. Further, in many foreign jurisdictions, the losing party must pay the attorneys’ fees of the winning
party, which can be substantial.

We may have to file one or more lawsuits in court to prevent a third party from selling a product or using a product in a manner that infringes our
patent, which could be expensive, time consuming and unsuccessful, and ultimately result in the loss of our proprietary market.

Because  competition  in  our  industry  is  intense,  competitors  may  infringe  or  otherwise  violate  our  issued  patents,  patents  of  our  licensors  or  other
intellectual  property.  To  counter  infringement  or  unauthorized  use,  we  may  be  required  to  file  infringement  lawsuits,  which  can  be  expensive  and  time
consuming. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their
patents. In addition, in a patent infringement proceeding, a court may decide that a patent of ours is invalid or unenforceable, in whole or in part, construe
the patent’s claims narrowly or refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology
in question. An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly. We may
also  elect  to  enter  into  license  agreements  in  order  to  settle  patent  infringement  claims  or  to  resolve  disputes  prior  to  litigation,  and  any  such  license
agreements may require us to pay royalties and other fees that could be significant. Furthermore, because of the substantial amount of discovery required in
connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure.

Because our CDK 4/6 inhibitor candidates are small molecules, after commercialization they will be subject in the United States to the patent litigation
process of the Hatch Waxman Act, which allows a generic company to submit an Abbreviated New Drug Application, or ANDA, to the FDA to obtain
approval to sell our drug using bioequivalence data only. Under the Hatch Waxman Act, we will have the opportunity to list all of our patents that cover our
drug product or its method of use in the FDA’s compendium of “Approved Drug Products with Therapeutic Equivalence Evaluation,” sometimes referred
to  as  the  FDA’s  Orange  Book.  A  generic  company  can  submit  an  ANDA  to  the  FDA  four  years  after  our  drug  approval  because  our  drug  products
candidates, COSELA and lerociclib, would be deemed new chemical entities. The submission of the ANDA by a generic company is considered a technical
act of patent infringement. The generic company can certify that it will wait until the natural expiration date of our listed patents to sell a generic version of
our product or can certify that one or more of our listed patents are invalid, unenforceable, or not infringed. If the latter, we will have 45 days to bring a
patent  infringement  lawsuit  against  the  generic  company.  This  will  initiate  a  challenge  to  one  or  more  of  our  Orange  Book  listed  patents  based  on
arguments from the generic company that either our patent is invalid, unenforceable or not infringed. Under the Hatch Waxman Act, if a lawsuit is brought,
the FDA is prevented from issuing a final approval on the generic drug until the earlier of seven-and-a-half years from our drug approval or a final decision
of a court holding that our asserted patent claims are invalid, unenforceable or not infringed. If we do not properly list our relevant patents in the Orange
Book,  or  timely  file  a  lawsuit  in  response  to  a  certification  from  a  generic  company  under  an  ANDA,  or  if  we  do  not  prevail  in  the  resulting  patent
litigation, we can lose our proprietary market, which can rapidly become generic. Further, even if we do correctly list our relevant patents in the Orange
Book, bring a lawsuit in a timely manner and prevail in that lawsuit, it may be at a very significant cost to us of attorneys’ fees and employee time and
distraction over a long period. Further, it is common for more than one generic company to try to sell an innovator drug at the same time, and so we may be
faced with the cost and distraction of multiple lawsuits. We may also determine it is necessary to settle the lawsuit in a manner that allows the generic
company to enter our market prior to the expiration of our patent or otherwise in a manner that adversely affects the strength, validity or enforceability of
our patent.

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain
and could have a material adverse effect on the success of our business.

We  may  become  party  to,  or  threatened  with,  adversarial  proceedings  or  litigation  regarding  intellectual  property  rights  covering  our  products  and
technology,  including  inter  parties  review  proceedings  before  the  U.S.  PTO.  Third  parties  may  assert  infringement  claims  against  us  based  on  existing
patents or patents that may be granted in the future. For example, we are aware that many companies, universities and institutions, including competitors,
have filed patent applications and received issued patents in our general areas of CDK 4/6 inhibitors and SERD compounds and their uses in methods of
treatment  and  combinations  with  other  drugs  as  well  as  their  processes  of  manufacture.  If  we  are  found  to  infringe  a  third  party’s  intellectual  property
rights,  we  could  be  required  to  litigate  the  validity  or  enforceability  of  the  third-party  asserted  patent,  which  may  be  expensive,  time-consuming  and
distracting  to  the  company,  and  which  litigation  we  may  lose.  We  may,  instead  of  litigating,  seek  to  obtain  a  license  from  such  third  party  to  continue
developing and marketing our products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or
at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We
could  be  forced,  including  by  court  order,  to  cease  commercializing  the  infringing  technology  or  product.  In  addition,  we  could  be  found  liable  for
monetary  damages,  including  treble  damages  and  attorneys’  fees  if  we  are  found  to  have  willfully  infringed  a  patent.  A  finding  of  infringement  could
prevent us from commercializing COSELA or force us to cease some of our business operations, which could materially harm our business. Claims that we
have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

A number of pharmaceutical companies have been the subject of intense review by the U.S. Federal Trade Commission or a corresponding agency in
another  country  based  on  how  they  have  conducted  or  settled  drug  patent  litigation,  and  certain  reviews  have  led  to  an  allegation  of  an  anti-trust
violation, sometimes resulting in a fine or loss of rights. We cannot be sure that we would not also be subject to such a review or that the result of the
review would be favorable to us, which could result in a fine or penalty.

The U.S. Federal Trade Commission, or FTC, has brought a number of lawsuits in federal court in the past few years to challenge Hatch Waxman ANDA
litigation settlements between innovator companies and generic companies as anti-competitive. The FTC has taken an aggressive position that anything of
value is a payment, whether money is paid or not. Under their approach, if an innovator as part of a patent settlement agrees not to launch or delay launch
of an authorized generic during the 180-day period granted to the first generic company to challenge an Orange Book listed patent covering an innovator
drug, or negotiates a delay in entry without payment, the FTC may consider it an unacceptable reverse payment. The biopharmaceutical industry argues
that such agreements are rational business decisions to dismiss risk and are immune from antitrust attack if the terms of the settlement are within the scope
of  the  exclusionary  potential  of  the  patent.  In  2013,  the  U.S.  Supreme  Court,  in  a  five-to-three  decision  in  FTC  v.  Actavis,  Inc.  rejected  both  the
biopharmaceutical  industry’s  and  FTC’s  arguments  with  regard  to  so-called  reverse  payments,  and  held  that  whether  a  “reverse  payment”  settlement
involving the exchange of consideration for a delay in entry is subject to an anticompetitive analysis depends on five considerations: (a) the potential for
genuine adverse effects on competition; (b) the justification of payment; (c) the patentee’s ability to bring about anticompetitive harm; (d) whether the size
of the payment is a workable surrogate for the patent’s weakness; and (e) that antitrust liability for large unjustified payments does not prevent litigating
parties from settling their lawsuits, for example, by allowing the generic to enter the market before the patent expires without the patentee’s paying the
generic. Furthermore, whether a reverse payment is justified depends upon its size, its scale in relation to the patentee’s anticipated future litigation costs,
its independence from other services for which it might represent payment, as was the case in Actavis, and the lack of any other convincing justification.
The Court held that reverse payment settlements can potentially violate antitrust laws and are subject to the standard antitrust rule-of-reason analysis, with
the burden of proving that an agreement is unlawful on the FTC and leaving to lower courts the structuring of such rule of reason analysis. If we are faced
with drug patent litigation, including Hatch

60

Waxman litigation with a generic company, we could be faced with such an FTC challenge based on that activity, including how or whether we settle the
case, and even if we strongly disagree with the FTC’s position, we could face a significant expense or penalty.

We may not be able to effectively enforce our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on COSELA, lerociclib and rintodestrant in all countries throughout the world would be prohibitively expensive,
and  therefore  we  only  file  for  patent  protection  in  selected  countries.  The  requirements  for  patentability  may  differ  in  certain  countries,  particularly  in
developing  countries.  Moreover,  our  ability  to  protect  and  enforce  our  intellectual  property  rights  may  be  adversely  affected  by  unforeseen  changes  in
foreign intellectual property laws.

The laws of foreign countries may not protect our rights to the same extent as the laws of the United States. For example, Europe, India, China and certain
other countries do not allow patents for methods of treating the human body. Many companies have encountered significant problems in protecting and
defending intellectual property rights in certain foreign jurisdictions that do not favor patent protection on drugs. This could make it difficult for us to stop
the  infringement  of  our  patents  or  the  misappropriation  of  our  other  intellectual  property  rights.  Competitors  may  use  our  technologies  in  jurisdictions
where we have not obtained patent protection to develop their own drugs and, further, may export otherwise infringing drugs to territories where we have
patent protection, if our ability to enforce our patents to stop infringing activities is inadequate. These drugs may compete with COSELA, and our patents
or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Proceedings  to  enforce  our  patent  rights  in  foreign  jurisdictions,  whether  or  not  successful,  could  result  in  substantial  costs  and  divert  our  efforts  and
resources from other aspects of our business. Furthermore, while we intend to protect our intellectual property rights in the major markets for COSELA, we
cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market it. Accordingly, our efforts to
protect our intellectual property rights in such countries may be inadequate.

A number of foreign countries have stated that they are willing to issue compulsory licenses to patents held by innovator companies on approved drugs to
allow the government or one or more third party companies to sell the approved drug without the permission of the innovator patentee where the foreign
government concludes it is in the public interest. India, for example, has used such a procedure to allow domestic companies to make and sell patented
drugs without innovator approval. There is no guarantee that patents covering any of our drugs will not be subject to a compulsory license in a foreign
country, or that we will have any influence over if or how such a compulsory license is granted. Further, Brazil allows its regulatory agency ANVISA to
participate in deciding whether to grant a drug patent in Brazil, and patent grant decisions are made based on several factors, including whether the patent
meets the requirements for a patent and whether such a patent is deemed in the country’s interest. In addition, several other countries have created laws that
make  it  more  difficult  to  enforce  drug  patents  than  patents  on  other  kinds  of  technologies.  Further,  under  the  treaty  on  the  Trade-Related  Aspects  of
Intellectual Property, or TRIPS, as interpreted by the Doha Declaration, countries in which drugs are manufactured are required to allow exportation of the
drug to a developing country that lacks adequate manufacturing capability. Therefore, our drug markets in the United States or foreign countries may be
affected by the influence of current public policy on patent issuance, enforcement or involuntary licensing in the healthcare area.

In addition, in November 2015, members of the World Trade Organization, or the WTO, which administers TRIPS, voted to extend the exemption against
enforcing pharmaceutical drug patents in least developed countries until 2033. We currently have no patent applications filed in least developed countries,
and our current intent is not to file in these countries in the future, at least in part due to this WTO pharmaceutical patent exemption.

Some  intellectual  property  may  have  been  discovered  through  government  funded  programs  and  thus  may  be  subject  to  federal  regulations  such  as
“march-in”  rights,  certain  reporting  requirements  and  a  preference  for  U.S.-based  companies.  Compliance  with  such  regulations  may  limit  our
exclusive rights, and limit our ability to contract with non-U.S. manufacturers.

Many of our intellectual property rights were generated through the use of U.S. government funding and are therefore subject to certain federal regulations.
As a result, the U.S. government may have certain rights to intellectual property embodied in our current or future product candidates pursuant to the Bayh-
Dole Act of 1980, or Bayh-Dole Act. These U.S. government rights in certain inventions developed under a government-funded program include a non-
exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right,
under certain limited circumstances, to require us to grant exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a third party
if it determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or
safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also referred to as “march-in rights”).
The U.S. government also has the right to take title to these inventions if we fail to disclose the invention to the government or fail to file an application to
register the intellectual property within specified time limits. Intellectual property generated under a government funded program is also subject to certain
reporting requirements, compliance with which may require us to expend substantial resources. In addition, the U.S. government requires that any products
embodying the subject invention or

61

produced through the use of the subject invention be manufactured substantially in the United States. The manufacturing preference requirement can be
waived if the owner of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to
potential  licensees  that  would  be  likely  to  manufacture  substantially  in  the  United  States  or  that  under  the  circumstances  domestic  manufacture  is  not
commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. product manufacturers for products covered
by such intellectual property. To the extent any of our current or future intellectual property is generated through the use of U.S. government funding, the
provisions of the Bayh-Dole Act may similarly apply.

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

In addition to seeking patents for some of our technology and products, we also rely on trade secrets, including unpatented know-how, technology and other
proprietary  information,  to  maintain  our  competitive  position.  We  seek  to  protect  these  trade  secrets,  in  part,  by  entering  into  non-disclosure  and
confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific collaborators, contract
manufacturers,  consultants,  advisors  and  other  third  parties.  We  seek  to  protect  our  confidential  proprietary  information,  in  part,  by  entering  into
confidentiality and invention or patent assignment agreements with our employees and consultants, however, we cannot be certain that such agreements
have been entered into with all relevant parties. Moreover, to the extent we enter into such agreements, any of these parties may breach the agreements and
disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim
that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition,
some  courts  inside  and  outside  the  United  States  are  less  willing  or  unwilling  to  protect  trade  secrets.  If  any  of  our  trade  secrets  were  to  be  lawfully
obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that
technology  or  information  to  compete  with  us.  If  any  of  our  trade  secrets  were  to  be  disclosed  to  or  independently  developed  by  a  competitor,  our
competitive position would be harmed.

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

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be due to be paid to the U.S.
PTO and various governmental patent agencies outside of the United States in several stages over the lifetime of the patents and/or applications. We have
systems in place to remind us to pay these fees, and we employ an outside firm and rely on our outside counsel to pay these fees due to non-U.S. patent
agencies. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a
late fee or by other means in accordance with the applicable rules. However, there are situations in which non-compliance can result in abandonment or
lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors
might be able to enter the market and this circumstance would have a material adverse effect on our business.

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities.

Litigation  or  other  legal  proceedings  relating  to  intellectual  property  claims,  with  or  without  merit,  is  unpredictable  and  generally  expensive  and  time
consuming and is likely to divert significant resources from our core business, including distracting our technical and management personnel from their
normal responsibilities. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a
risk  that  some  of  our  confidential  information  could  be  compromised  by  disclosure  during  this  type  of  litigation.  In  addition,  there  could  be  public
announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results
to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings could substantially increase our
operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities.

We  may  not  have  sufficient  financial  or  other  resources  to  adequately  conduct  such  litigation  or  proceedings.  Some  of  our  competitors  may  be  able  to
sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed
intellectual property portfolios. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating or
from  successfully  challenging  our  intellectual  property  rights.  Uncertainties  resulting  from  the  initiation  and  continuation  of  patent  litigation  or  other
proceedings could have a material adverse effect on our ability to compete in the marketplace.

62

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership
of what we regard as our own intellectual property.

Many  of  our  employees  were  previously  employed  at  universities  or  other  biotechnology  or  pharmaceutical  companies,  including  our  competitors  or
potential competitors. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we
may be subject to claims that these employees or we have used or disclosed intellectual property, including trade secrets or other proprietary information, of
any such employee’s former employer. Litigation may be necessary to defend against these claims.

In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property to execute
agreements  assigning  such  intellectual  property  to  us,  we  may  be  unsuccessful  in  executing  such  an  agreement  with  each  party  who  in  fact  develops
intellectual property that we regard as our own. Our and their assignment agreements may not be self-executing or may be breached, and we may be forced
to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.

If  we  fail  in  prosecuting  or  defending  any  such  claims,  in  addition  to  paying  monetary  damages,  we  may  lose  valuable  intellectual  property  rights  or
personnel.  Even  if  we  are  successful  in  prosecuting  or  defending  against  such  claims,  litigation  could  result  in  substantial  costs  and  be  a  distraction  to
management.

Risks related to our common stock

The price of our common stock may be volatile and fluctuate substantially.

The market price of shares of our common stock could be subject to wide fluctuations in response to many risk factors listed in this section, and others
beyond our control, including:

•
•
•
•
•
•
•
•
•

•
•
•
•
•

•

results of preclinical and clinical trials;
results of clinical trials of our competitors’ products;
regulatory actions with respect to our products or our competitors’ products;
actual or anticipated fluctuations in our financial condition and operating results;
publication of research reports by securities analysts about us or our competitors or our industry;
our failure or the failure of our competitors to meet analysts’ projections or guidance that we or our competitors may give to the market;
developments or disputes concerning patent applications, issued patents or other proprietary rights;
additions and departures of key personnel;
strategic decisions by us or our competitors, such as acquisitions, collaborations, divestitures, spin-offs, joint ventures, strategic investments
or changes in business strategy;
the passage of legislation or other regulatory developments in the United States and other countries affecting us or our industry;
fluctuations in the valuation of companies perceived by investors to be comparable to us;
sales of our common stock by us, our insiders or our other stockholders;
speculation in the press or investment community;
announcement or expectation of additional financing efforts;
changes in accounting principles;
changes in the structure of healthcare payment systems;
terrorist acts, acts of war or periods of widespread civil unrest;
natural disasters and other calamities;
changes in market conditions for pharmaceutical and biopharmaceutical stocks;
changes in general market, industry and economic conditions; and
the other factors described in this “Risk Factors” section.

In  addition,  the  stock  market  has  experienced  significant  volatility,  particularly  with  respect  to  pharmaceutical,  biotechnology  and  other  life  sciences
company stocks. The volatility of pharmaceutical, biotechnology and other life sciences company stocks often does not relate to the operating performance
of  the  companies  represented  by  the  stock.  In  the  past,  securities  class  action  litigation  has  often  been  initiated  against  companies  following  periods  of
volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources, and could also
require us to make substantial payments to satisfy judgments or to settle litigation.

63

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Provisions in our corporate charter documents and under Delaware law could make an acquisition of our company, which may be beneficial to our
stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions  in  our  certificate  of  incorporation  and  our  by-laws  may  discourage,  delay  or  prevent  a  merger,  acquisition  or  other  change  in  control  of  our
company  that  stockholders  may  consider  favorable,  including  transactions  in  which  you  might  otherwise  receive  a  premium  for  your  shares.  These
provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price
of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may
frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace
members of our board of directors. Although we believe these provisions collectively provide for an opportunity to obtain greater value for stockholders by
requiring potential acquirers to negotiate with our board of directors, they would apply even if an offer rejected by our board of directors were considered
beneficial by some stockholders. Among other things, these provisions:

•
•
•
•

•

•
•

•

establish a classified board of directors such that only one of three classes of directors is elected each year;
allow the authorized number of our directors to be changed only by resolution of our board of directors;
limit the manner in which stockholders can remove directors from our board of directors;
establish advance notice requirements for stockholder proposals that can be acted on at stockholder meetings and nominations to our board of
directors;
require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written
consent;
limit who may call stockholder meetings;
authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that
would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by
our board of directors; and
require the approval of the holders of at least two-thirds of the voting power of all of the then-outstanding shares of capital stock that would
be entitled to vote generally in the election of directors to amend or repeal specified provisions of our certificate of incorporation or by-laws.

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which
prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date
of  the  transaction  in  which  the  person  acquired  in  excess  of  15%  of  our  outstanding  voting  stock,  unless  the  merger  or  combination  is  approved  in  a
prescribed manner.

We have incurred and will continue to incur increased costs as a result of operating as a public company, and our management will be required to
devote substantial time to new compliance initiatives and corporate governance practices.

As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses. The Sarbanes-Oxley Act of 2002, the
Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of The Nasdaq Stock Market and other applicable securities rules
and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls
and corporate governance practices. Our management and other personnel devote a substantial amount of time to these compliance initiatives. Moreover,
these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly. For example, these
rules and regulations make it more difficult and more expensive for us to obtain director and officer liability insurance.

Our certificate of incorporation includes a forum selection clause, which could limit our stockholders’ ability to obtain a favorable judicial forum for
disputes with us.

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of
Delaware will be the sole and exclusive forum for any stockholder to bring (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, officers, or employees to us or to our stockholders, (iii) any action asserting a
claim arising pursuant to any provision of the Delaware General Corporation Law or our certificate of incorporation or by-laws, or (iv) any action asserting
a claim governed by the internal affairs doctrine; in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as
defendants. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to
the foregoing provisions. This forum selection provision in our certificate of incorporation may limit our stockholders’ ability to obtain a favorable judicial
forum for disputes with us. It is also possible that, notwithstanding the forum selection clause included in our certificate of incorporation, a court could rule
that such a provision is inapplicable or unenforceable.

We do not anticipate paying any cash dividends on our capital stock in the foreseeable future.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth
and  development  of  our  business.  In  addition,  the  terms  of  any  future  debt  agreements  may  preclude  us  from  paying  dividends.  As  a  result,  capital
appreciation, if any, of our common stock will be the sole source of gain for our stockholders for the foreseeable future.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our corporate headquarters is located in Research Triangle Park, North Carolina, where we lease approximately 60,000 square feet of laboratory and office
space.  This lease on our corporate headquarters commenced in September 2019 and expires on September 30, 2027. None of our leases are material to our
business operations. We believe our facility is adequate for our current needs and that suitable additional or substitute space would be available if needed.

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  financial  statements  and
related notes included elsewhere in this Annual Report. This discussion contains forward-looking statements that involve risk and uncertainties, such as
statements of our plans, objectives, expectations and intentions. As a result of many factors, including those factors set forth in the “Risk Factors” section
of this Annual Report, 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.

Overview

We are a commercial-stage biopharmaceutical company focused on the development and commercialization of novel small molecule therapeutics for the
treatment of patients with cancer. Our first product approved by the FDA, COSELA™ (trilaciclib), is the first and only therapy indicated to proactively
help protect bone marrow from the damage of chemotherapy and is the first innovation in managing myeloprotection in decades.

We  shall  use  “COSELA”  when  referring  to  our  FDA  approved  drug  and  “trilaciclib”  when  referring  to  our  development  of  COSELA  for  additional
indications.  

COSELA is a prescription medicine used to help reduce the occurrence of low blood cell counts caused by damage to bone marrow from chemotherapy.
COSELA is used to treat adults taking certain chemotherapies (platinum/etoposide or topotecan) for extensive-stage small cell lung cancer.

COSELA is an injection for intravenous (IV) use given within 4 hours before chemotherapy.

Commercial Product

On February 12, 2021, COSELA (trilaciclib) for injection was approved by the FDA to decrease the incidence of chemotherapy-induced myelosuppression
in adult patients treated with a platinum/etoposide-containing regimen or topotecan-containing regimen for ES-SCLC. We are also exploring potential use
of trilaciclib in a variety of tumors, including colorectal cancer (“CRC”), breast cancer, bladder cancer, and in trials designed to inform the design of future
additional  pivotal  studies  across  multiple  tumor  types  and  treatment  combinations  including  targeted  chemotherapy  medicines  called  antibody-drug
conjugates (ADCs).

In  June  2020,  we  entered  into  a  three-year  co-promotion  agreement  for  COSELA  in  the  United  States  and  Puerto  Rico  with  Boehringer  Ingelheim
Pharmaceuticals, Inc. In December 2021, G1 and Boehringer Ingelheim mutually agreed to end the co-promotion agreement for COSELA, effective March
2022. At that time, the Company announced that it would hire and deploy a total of 34 oncology sales representatives to allow G1 to target all accounts to
accelerate sales activities and help maximize the adoption of COSELA. As of February 21, 2022, all 34 sales representatives have been hired, trained, and
deployed.

Product Pipeline

Trilaciclib is a first-in-class therapy designed to help protect against chemotherapy-induced myelosuppression.

We are executing on our tumor-agnostic strategy to evaluate the potential benefits of trilaciclib to patients with other tumors to continuously develop new
data with trilaciclib in a variety of chemotherapeutic settings and in combination with other agents to maximize the applicability of the drug to potential
future treatment paradigms. We currently have five on-going clinical trials: a pivotal trial in 1L colorectal cancer (“CRC”), a pivotal trial in 1L mTNBC, a
Phase  2  1L  bladder  cancer  trial  with  chemotherapy  and  a  checkpoint  inhibitor,  a  Phase  2  trial  designed  to  evaluate  the  antitumor  efficacy  and
myeloprotective  benefit  of  trilaciclib  administered  prior  to  an  antibody-drug  conjugate  (“ADC”),  and  a  Phase  2  trial  in  neoadjuvant  TNBC  designed  to
validate trilaciclib’s immune-based mechanism of action (“MOA”). These studies across treatment settings and tumor types will evaluate trilaciclib’s dual
benefits in both multi-lineage myeloprotection and anti-tumor efficacy. In addition, the MOA and ADC trials will inform the design of future additional
pivotal  studies  across  multiple  tumor  types  and  treatment  combinations.  The  Company  is  also  conducting  significant  preclinical  work  to  assess  the
additive/synergistic potential of trilaciclib with a variety of novel and emerging therapeutic agents to identify synergies to evaluate in future clinical trials.
G1’s clinical approach to designing our clinical program includes monitoring the evolution of future standards of care and develop trilaciclib with these in
mind, allowing us to conduct or support trials that will generate important data to maximize future usage in a variety of future settings.

Lerociclib

Lerociclib is a differentiated oral CDK4/6 inhibitor being developed for use in combination with other targeted therapies in multiple oncology indications.
In 2020, we entered into separate, exclusive agreements with EQRx, Inc. (rights for U.S., Europe, Japan and all markets outside Asia-Pacific) and Genor
Biopharma Co. Inc. (rights for Asia-Pacific, excluding Japan) for the development and commercialization of lerociclib in all indications. Combined, these
agreements  provided  $26.0  million  in  upfront  payments,  along  with  sales-based  royalties,  and  the  opportunity  for  up  to  $330.0  million  in  potential
milestone payments. EQRx, Inc. and Genor Biopharma Co. Inc. are responsible for all costs related to the development and commercialization of lerociclib
in their respective territories.

Rintodestrant

Rintodestrant is a clinical-stage oral SERD, for use as a monotherapy and in combination with CDK4/6 inhibitors, initially Ibrance® (palbociclib), for the
treatment of ER+, HER2- breast cancer. We are in the process of evaluating partnering options for rintodestrant.

CDK2 Inhibitor
In 2020, we entered into a global license agreement with ARC Therapeutics, LLC for the development and commercialization of an internally discovered
CDK2 inhibitor for all human and veterinary uses. ARC is currently granted an exclusive, royalty-bearing, license with the right to grant sublicenses to one
of our solely owned patent families.

Coronavirus (COVID-19) impact on operations

We  have  implemented  business  continuity  plans  to  address  the  COVID-19  pandemic  and  minimize  disruptions  to  ongoing  operations.  Enrollment  of
patients in current and future clinical trials may be impacted by COVID-19. Although we have not had any significant supply chain delays or shortages as a
result of the COVID-19 pandemic to date, we have experienced delays in the delivery of our investigational product to certain investigative sites due to
shortages  of  ancillary  materials  and  the  delay  of  governmental  inspections.    To  date,  we  are  on  track  to  meet  all  of  our  previously  announced  clinical
milestones.  If  the  COVID-19  pandemic  continues  or  increases  in  severity,  we  could  experience  disruptions  to  our  clinical  development  timelines.  If  we
experience  delays  in  patient  enrollment,  we  could  incur  increased  clinical  program  expense  if  it  is  deemed  necessary  or  advisable  to  improve  patient
recruitment by opening additional clinical sites. COVID-19 travel limitations and government-mandated work-from-home or shelter-in-place orders, may
reduce the number of in-person meetings with prescribers and fewer patient visits with physicians, potentially resulting in fewer new prescriptions.

We  established  a  COVID-19  response  team  which  continually  monitors  the  impact  of  COVID-19  on  our  operations.    The  COVID-19  response  team
manages our workplace protocols that govern our employees’ use of our office. To mitigate the impact of COVID-19 on our business, we put in place the
following safety measures for our employees, patients, healthcare professionals, and suppliers to limit exposure: we substantially restricted travel, supplied
personal protective equipment to employees, limited access to our headquarters and asked most of our staff to work remotely. As of December 31, 2021,
the majority of our employees are still working remotely, which may negatively impact our ability to conduct research and development activities, engage
in  sales-related  initiatives,  or  efficiently  conduct  day-to-day  operations.  In  addition,  we  added  bandwidth  and  VPN  capacity  to  our  infrastructure  to
facilitate remote work arrangements. We will continue to monitor the impact of COVID-19 on our operations, including how it will impact our employees,
clinical trials, development programs, supply chain, and other aspects of our operations, and report to our Board of Directors regularly on the progress of
our response to the COVID-19 outbreak.

Financial Overview

Since our inception in 2008, we have devoted substantially all of our resources to synthesizing, acquiring, testing and developing our product candidates,
including conducting preclinical studies and clinical trials and providing selling, general and administrative support for these operations as well as securing
intellectual  property  protection  for  our  products.  Currently,  COSELA  is  our  only  product  approved  for  sale.  We  began  generating  revenue  for  the  net
product sales from COSELA in March of 2021.We recorded $11.1 million of net product sales from COSELA and $20.4 million of license revenue for the
year ended December 31, 2021, and $45.3 million of license revenue for the year ended December 31, 2020. To date, we have financed our operations
primarily  through  the  sale  of  equity  securities,  our  loan  agreement  with  Hercules  Capital,  Inc.,  and  licensing  arrangements.  Under  our  licensing
arrangements, we are eligible to receive certain development and sales-based milestones. Our ability to earn these milestones and the timing of achieving
these milestones is primarily dependent upon the outcome of the licensee’s activities and is uncertain at this time.

As of December 31, 2021, we had cash and cash equivalents of $221.2 million. Since inception, we have incurred net losses. Our net losses were
$148.4 million, $99.3 million and $122.4 million for the years ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021, we had
an accumulated deficit of $584.5 million. Substantially all of our net losses have resulted from costs incurred in connection with our research and
development programs, our commercial launch of COSELA, and from selling, general and administrative expenses associated with our operations. We
expect our research and development, commercial activities, and selling, general and administrative expenses will continue to increase in connection with
our ongoing and future activities as we:

•

•

•

•

•

•

•

•

•

continue development of trilaciclib, including initiation of additional clinical trials

identify and develop new product candidates;

seek additional marketing approvals for trilaciclib upon successful completion of clinical trials;

grow  our  sales,  marketing  and  distribution  infrastructure  to  commercialize  COSELA  and  any  future  products  for  which  we  may  obtain
marketing approval;

achieve market acceptance of our products in the medical community and with third-party payors;

maintain, expand and protect our intellectual property portfolio;

hire additional personnel;

enter into collaboration arrangements, if any, for the development of our products or in-license other products and technologies;

identify and develop new product candidates;

72

 
 
 
 
 
 
 
 
 
 
 
•

•

add operational, financial and management information systems and personnel, including personnel to support our product development and
planned future commercialization efforts; and

continue to incur increased costs as a result of operating as a public company.

Components of our Results of Operations

Revenues

On February 12, 2021, COSELA was approved by the FDA and we began generating revenue for the product sales of COSELA in March 2021. Prior to the
approval of COSELA, our revenues were derived solely from our license agreements.

We entered into an exclusive license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd (“Simcere”) in August 2020 and granted them
the  rights  to  develop  and  commercialize  trilaciclib  in  Greater  China  (mainland  China,  Hong  Kong,  Macau,  and  Taiwan)  (the  “Simcere  Territory”).  We
received an upfront payment of $14.0 million (less applicable withholding taxes of $1.4 million) in September 2020. This was recognized as revenue once
the  transfer  of  the  license  and  related  technology  and  know-how  was  completed  in  the  fourth  quarter  of  2020.  We  have  the  potential  to  receive  $156.0
million  upon  reaching  development  and  commercial  milestones,  and  receive  tiered  low  double-digit  royalties  on  annual  net  sales  of  trilaciclib  in  the
Simcere Territory. During the twelve months ended December 31, 2021, three development milestones totaling $8.0 million (less applicable withholding
taxes of $0.8 million) were received and recognized as revenue.

We  entered  into  an  exclusive  license  agreement  with  EQRx,  Inc.  (“EQRx”)  in  July  2020  and  granted  them  the  rights  to  develop  and  commercialize
lerociclib in the United States, Europe, Japan and all other global markets, excluding the Asia-Pacific region (except Japan) (the “EQRx Territory”). We
received an upfront payment of $20.0 million in August 2020. This was recognized as revenue in September 2020 when we transferred the license and
related technology and know-how. We have the potential to receive $290.0 million upon reaching development and commercial milestones, and receive
tiered royalties ranging from mid-single digits to mid-teens based on annual net sales of lerociclib in the EQRx Territory.

We  entered  into  an  exclusive  license  agreement  with  Genor  Biopharma  Co.  Inc.  (“Genor”)  in  June  2020  and  granted  them  the  rights  to  develop  and
commercialize  lerociclib  in  the  Asia-Pacific  Region,  excluding  Japan  (the  “Genor  Territory”).  We  received  an  upfront  payment  of  $6.0  million  in  July
2020. This was recognized as revenue in September 2020 when we transferred the license and related technology and know-how. We have the potential to
receive $40.0 million upon reaching development and commercial milestones, and receive tiered royalties ranging from high single to low double-digits
based on annual net sales of lerociclib in the Genor Territory. During the twelve months ended December 31, 2021, one development milestone totaling
$3.0 million was received and recognized as revenue.

We entered into an exclusive license agreement with ARC Therapeutics, LLC (“ARC”) in May 2020.  We granted ARC an exclusive, worldwide, royalty-
bearing license of its CDK2 inhibitor compounds in exchange for an upfront payment and equity in ARC with a total value of approximately $2.1 million,
which resulted in the recognition of related party revenue. We are entitled to receive additional milestone payments and sales-based royalties, and has right
of first negotiation to re-acquire these assets.

Operating expenses

We classify our operating expenses into three categories: cost of goods sold, research and development and selling, general and administrative expenses.
Personnel costs, including salaries, benefits, bonuses and stock-based compensation expense, comprise a significant component of each of these expense
categories. We allocate expenses associated with personnel costs based on the nature of work associated with these resources.

Cost of goods sold

Cost of goods sold includes direct and indirect costs related to the manufacturing and distribution of COSELA, including third-party manufacturing costs,
packaging services, freight-in, third-party logistics costs associated with COSELA, and personnel costs. Cost of goods sold may also include period costs
related to certain inventory manufacturing services and inventory adjustment charges.

Research and Development Expenses

The largest component of our total operating expenses since inception has been research and development activities, including the preclinical and clinical
development of our product candidates.

Research and development costs are expensed as incurred. Our research and development expense primarily consists of:

•

salaries and personnel-related costs, including bonuses, benefits and any stock-based compensation, for our scientific personnel performing or
managing out-sourced research and development activities;

73

 
 
 
 
•

•

•

•

•

costs incurred under agreements with contract research organizations and investigative sites that conduct preclinical studies and clinical trials;

costs related to manufacturing pharmaceutical active ingredients and drug products for preclinical studies and clinical trials;

costs related to upfront and milestone payments under in-licensing agreements;

fees paid to consultants and other third parties who support our product development;

allocated facility-related costs and overhead.

The successful development of our products are highly uncertain. Products in later stages of clinical development generally have higher development costs
than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. Accordingly, we expect
research and development costs to increase as we conduct later stage clinical trials. However, we do not believe that it is possible at this time to accurately
project total program-specific expenses through commercialization. Our expenditures on current and future preclinical and clinical development programs
are subject to numerous uncertainties in timing and cost to completion. The duration, costs and timing of clinical trials and development of products will
depend on a variety of factors including:

•

•

•

•

•

•

•

the scope, rate of progress, and expenses of our ongoing as well as any additional clinical trials and other research and development activities;

future clinical trial results;

achievement of milestones requiring payments under our in-licensing agreements;

uncertainties in clinical trial enrollment rates or drop-out or discontinuation rates of patients;

potential additional studies requested by regulatory agencies;

significant and changing government regulation; and

the timing and receipt of any regulatory approvals.

We  track  research  and  development  expenses  on  a  program-by-program  basis  only  for  clinical-stage  product  candidates.  Preclinical  research  and
development expenses and chemical manufacturing research and development expenses are not assigned or allocated to individual development programs.
In 2021, we had two clinical-stage products, trilaciclib and rintodestrant.

Selling, general and administrative expenses

Selling, general and administrative expenses consist of personnel costs, allocated expenses and other expenses for outside professional services, including
legal,  audit  and  accounting  services.  Personnel  costs  consist  of  salaries,  bonuses,  benefits  and  stock-based  compensation.  Other  selling,  general  and
administrative  expenses  include  facility-related  costs  not  otherwise  allocated  to  research  and  development  expense,  professional  fees,  pre-
commercialization costs, expenses associated with obtaining and maintaining patents and costs of our information systems. We anticipate that our selling,
general and administrative expenses will continue to increase in the future as we increase our headcount to support our continued research and development
and commercialization of COSELA.

We expect to continue to incur additional selling, general and administrative expenses in the future in connection with the commercialization of COSELA,
as  we  support  continued  research  and  development  activities,  and  as  we  support  our  operations  in  a  public  company  environment,  including  expenses
related  to  compliance  with  the  rules  and  regulations  of  the  SEC  and  Nasdaq,  additional  insurance  expenses,  and  expenses  related  to  investor  relations
activities.

Total other income (expense), net

Total  other  income  (expense),  net  consists  of  interest  income  earned  on  cash  and  cash  equivalents  and  interest  expenses  incurred  under  our  loan  and
security agreement with Hercules.

Income taxes

To  date,  we  have  not  been  required  to  pay  U.S.  federal  or  state  income  taxes  because  we  have  not  generated  taxable  income.  Income  tax  expense
recognized in 2021 and 2020 related to the foreign withholding taxes incurred as a result of the Simcere license agreement.

Critical accounting policies and significant judgments and estimates

This  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  is  based  on  our  financial  statements,  which  have  been  prepared  in
accordance with U.S. generally accepted accounting principles. The preparation of our financial statements requires us to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well
as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we
believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities
that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in the notes to our financial statements appearing elsewhere in this Annual Report, we
believe that the following accounting policies are critical to the process of making significant judgments and estimates in the preparation of our financial
statements and understanding and evaluating our reported financial results.

Revenue Recognition

For elements of those arrangements that we determine should be accounted for under ASC 606, Revenue from Contracts with Customers (“ASC 606”), we
assess which activities in our license or collaboration agreements are performance obligations that should be accounted for separately and determine the
transaction  price  of  the  arrangement,  which  includes  the  assessment  of  the  probability  of  achievement  of  future  milestones  and  other  potential
consideration.  For  arrangements  that  include  multiple  performance  obligations,  such  as  granting  a  license  or  performing  manufacturing  or  research  and
development  activities,  we  allocate  the  transaction  price  based  on  the  relative  standalone  selling  price  and  recognize  revenue  that  is  allocated  to  the
respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. Accordingly, we develop
assumptions  that  require  judgment  to  determine  the  standalone  selling  price  for  each  performance  obligation  identified  in  the  contract.  These  key
assumptions may include revenue forecasts, clinical development timelines and costs, discount rates and probabilities of clinical and regulatory success.

License Revenue

Licenses of Intellectual Property

If  a  license  to  our  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the  arrangement,  we  recognize
revenue allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that
are  bundled  with  other  promises,  we  utilize  judgment  to  assess  the  nature  of  the  combined  performance  obligation  to  determine  whether  the  combined
performance  obligation  is  satisfied  over  time  or  at  a  point  in  time  and,  if  over  time,  the  appropriate  method  of  measuring  progress  for  purposes  of
recognizing  revenue  associated  with  the  bundled  performance  obligation.  We  evaluate  the  measure  of  progress  each  reporting  period  and,  if  necessary,
adjusts the measure of progress and related revenue recognition.

Milestone Payments

At  the  inception  of  each  arrangement  that  includes  developmental  and  regulatory  milestone  payments,  we  evaluate  whether  the  achievement  of  each
milestone specifically relates to our efforts to satisfy a performance obligation or transfer a distinct good or service within a performance obligation. We
evaluates  each  milestone  to  determine  when  and  how  much  of  the  milestone  to  include  in  the  transaction  price.  We  first  estimates  the  amount  of  the
milestone payment that we could receive using either the expected value or the most likely amount approach. We primarily uses the most likely amount
approach  as  that  approach  is  generally  most  predictive  for  milestone  payments  with  a  binary  outcome.  Then,  we  considers  whether  any  portion  of  that
estimated amount is subject to the variable consideration constraint (that is, whether it is probable that a significant reversal of cumulative revenue would
not  occur  upon  resolution  of  the  uncertainty).  We  update  the  estimate  of  variable  consideration  included  in  the  transaction  price  at  each  reporting  date
which  includes  updating  the  assessment  of  the  likely  amount  of  consideration  and  the  application  of  the  constraint  to  reflect  current  facts  and
circumstances.

75

 
 
Royalties

For  arrangements  that  include  sales-based  royalties,  including  milestone  payments  based  on  the  level  of  sales,  and  the  license  is  deemed  to  be  the
predominant  item  to  which  the  royalties  relate,  we  will  recognize  revenue  at  the  later  of  (i)  when  the  related  sales  occur,  or  (ii)  when  the  performance
obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, we have not recognized any revenue
related to sales-based royalties or milestone payments based on the level of sales.

Product Sales, Net

We sell COSELA to specialty distributors in the U.S. and, in accordance with ASC 606, recognizes revenue at the point in time when the customer is
deemed to have obtained control of the product. The customer is deemed to have obtained control of the product at the time of physical receipt of the
product at the customers’ distribution facilities, or Free on Board (“FOB”) destination, the terms of which are designated in the contract.

Product sales are recorded at the net selling price, which includes estimates of variable consideration for which reserves are established for (a) rebates and
chargebacks, (b) co-pay assistance programs, (c) distribution fees, (d) product returns, and (e) other discounts. Where appropriate, these estimates take into
consideration a range of possible outcomes which are probability-weighted for relevant factors such as current contractual and statutory requirements, and
forecasted customer buying and payment patterns. Overall, these reserves reflect our best estimates of the amount of consideration to which it is entitled
based on the terms of the applicable contract. The amount of variable consideration may be constrained and is included in the net sales price only to the
extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of
consideration ultimately received may differ from our estimates. If actual results in the future vary from estimates, we adjust these estimates, which would
affect net product revenue and earnings in the period such variances become known.

Liabilities related to co-pay assistance, rebates, and GPO fees are classified as “Accrued Expenses” in the Condensed Balance Sheets. Discounts such as
chargebacks, returns, and specialty distributor fees are recorded as a reduction to trade accounts receivable, which is included in “Accounts Receivable” in
the Condensed Balance Sheets.

Forms of Variable Consideration

Rebates and Chargebacks: We estimate reductions to product sales for Public Health Service Institutions, such as Medicaid, Medicare and Veterans
Administration (“VA”) programs, as well as certain other qualifying federal and state government programs, and other group purchasing organizations. We
estimate these reductions based upon our contracts with government agencies and other organizations, statutorily defined discounts and estimated payor
mix. These organizations purchase directly from our specialty distributors at a discount and the specialty distributors charge us back the difference between
the wholesaler price and the discounted price. Our liability for Medicaid rebates consists of estimates for claims that a state will make. We reserve for this
discounted pricing is based on expected sales to qualified healthcare providers and the chargebacks that customers have already claimed.

Co-pay assistance: Eligible patients who have commercial insurance may receive assistance from us to reduce the patient’s out of pocket costs. Liabilities
for co-pay assistance are calculated by actual program participation from third-party administrators.

Distribution Fees: We have written contracts with its customers that include terms for distribution fees and costs for inventory management. We estimate
and record distribution fees due to its customers based on gross sales.

Product Returns: We generally offers a right of return based on the product’s expiration date and certain spoilage and damaged instances. We estimate the
amount of product sales that may be returned and record the estimate as a reduction of product sales in the period the related product sales are recognized.
Our estimates for expected returns are based primarily on an ongoing analysis of sales information and visibility into the inventory remaining in the
distribution channel.

Cost of Goods Sold

Cost of goods sold includes direct and indirect costs related to the manufacturing and distribution of COSELA, including third-party manufacturing costs,
packaging services, freight-in, third-party logistics costs associated with COSELA, and our personnel costs. Cost of goods sold may also include period
costs related to certain inventory manufacturing services and inventory adjustment charges. In connection with the FDA approval of COSELA on February
12, 2021, we subsequently began capitalizing inventory manufactured or purchased after this date. As a result, certain manufacturing costs associated with
product shipments of COSELA were expensed prior to FDA approval and, therefore, are not included in cost of goods sold during the current period.

76

 
Accrued research and development expenses

As part of the process of preparing our financial statements, we estimate and accrue research and development expenses, including external clinical study
costs associated with clinical trial activities. The process involves reviewing contracts and purchase orders, identifying services that have been provided on
our behalf, and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise
notified of the actual costs.

Costs for clinical trial activities are recognized based on an evaluation of our vendors’ progress towards completion of specific tasks, using data such as
patient enrollment, clinical site activations or information provided to us by our vendors regarding their actual costs incurred. Payments for these activities
are  based  on  the  terms  of  individual  contracts  and  payment  timing  may  differ  significantly  from  the  period  in  which  the  services  were  performed.  We
determine  accrual  estimates  through  reports  from  and  discussions  with  applicable  personnel  and  outside  service  providers  as  to  the  progress  or  state  of
completion of trials, or the services completed. Our estimates of accrued external clinical study costs as of each balance sheet date are based on the facts
and circumstances known at the time.

Although  we  do  not  expect  our  estimates  to  be  materially  different  from  the  amounts  actually  incurred,  if  our  estimates  of  the  status  and  timing  of  the
services performed differ from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular
period. To date, there have been no material differences from our estimates to the amount actually incurred.

Stock-based compensation

We account for stock-based compensation awards in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification
(ASC)  Topic  718,  Compensation—Stock  Compensation,  or  ASC  718.  ASC  718  requires  all  stock-based  payments  to  employees,  including  grants  of
employee stock options, to be recognized in the statement of operations based on their fair values. Our stock-based compensation awards have historically
consisted of stock options.

We recognize compensation costs related to stock options granted to employees based on the estimated fair value of the awards on the date of grant. We
estimate the grant date fair value, and the resulting stock-based compensation expense, using the Black-Scholes option-pricing model. The grant date fair
value of the stock-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of
the respective awards. We account for forfeitures as they occur, rather than estimating forfeitures as of the date of grant.

We recorded non-cash stock-based compensation expense of $22.3 million, $18.8 million and $16.4 million for the years ended December 31, 2021, 2020
and 2019, respectively.

We  calculate  the  fair  value  of  stock  options  using  the  Black-Scholes  option-pricing  model.  The  Black-Scholes  option-pricing  model  requires  the  use  of
subjective assumptions, including the expected volatility of our common stock, the assumed dividend yield, the expected term of our stock options, the
risk-free interest rate for a period that approximates the expected term of our stock options, and the fair value of the underlying common stock on the date
of grant. In applying these assumptions, we considered the following factors:

•

•

•

•

•

we do not have sufficient history to estimate the volatility of our common stock; we calculate expected volatility based on reported data for
selected similar publicly traded companies for which the historical information is available as we do not have sufficient history to estimate
volatility  using  only  our  common  stock;  in  2019,  we  began  incorporating  our  historical  stock  price  in  conjunction  with  selected  similar
publicly  traded  companies;  we  plan  to  continue  to  use  the  guideline  peer  group  volatility  information  until  the  historical  volatility  of  our
common stock is sufficient to measure expected volatility for future option grants;

the assumed dividend yield of zero is based on our expectation of not paying dividends for the foreseeable future;

our estimates of expected term used in the Black-Scholes option-pricing model were based on the estimated time from the grant date to the
date of exercise;

we determine the risk-free interest rate by reference to implied yields available from U.S. Treasury securities with a remaining term equal to
the expected life assumed at the date of grant; and

we account for forfeitures as they occur, rather than estimating forfeitures as of an award’s grant date.

See “Note 10 – Stock-Based Compensation” to the accompanying audited financial statements included in Item 15 of this Annual Report for the weighted
average assumptions used in the Black-Scholes option-pricing model for awards granted in the years ended December 31, 2021, 2020 and 2019.

77

 
 
 
 
 
 
Prior to our initial public offering, the fair value of our common shares underlying our stock options was estimated on each grant date by our board of
directors.  In  order  to  determine  the  fair  value  of  our  common  shares  underlying  granted  stock  options,  our  board  of  directors  considered,  among  other
things,  timely  valuations  of  our  common  shares  prepared  by  an  unrelated  third-party  valuation  firm  in  accordance  with  the  guidance  provided  by  the
American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation.

Given the absence of a public trading market for our common shares, our board of directors exercised reasonable judgment and considered a number of
objective and subjective factors to determine the best estimate of the fair value of our common shares, including (1) our business, financial condition and
results of operations, including related industry trends affecting our operations; (2) our forecasted operating performance and projected future cash flows;
(3) the illiquid nature of our common shares; (4) liquidation preferences and other rights and privileges of our common shares; (5) market multiples of our
most comparable public peers and (6) market conditions affecting our industry. Since our IPO, our board of directors has determined the fair value of each
common share underlying share-based awards based on the closing price of our common shares as reported by the Nasdaq on the date of grant.

Income taxes

We recognize deferred income taxes for temporary differences between the basis of assets and liabilities for financial statement and income tax purposes.
We  periodically  evaluate  the  positive  and  negative  evidence  bearing  upon  the  ability  to  realize  our  deferred  tax  assets.  Based  upon  the  weight  of  the
available evidence, which includes historical operating performance, reported cumulative net losses since inception and difficulty in accurately forecasting
our future results, we maintained a full valuation allowance on the net deferred tax assets for all periods presented. We intend to maintain a full valuation
allowance on the U.S. deferred tax assets for the foreseeable future until sufficient positive evidence exists to support reversal of the valuation allowance.

At December 31, 2021, we have federal net operating loss carryforwards (“NOLs”) of approximately $510.0 million, which are available to offset future
taxable income. Of the $510.0 million available, $95.4 million will begin to expire in 2029. The remaining $414.6 million has an indefinite carryforward
period. Under the Tax Cuts and Jobs Act (“Tax Act”), federal NOLs arising after December 31, 2017 may be carried forward indefinitely. However, for
NOLs arising after December 31, 2017, NOL carryforwards will be limited to 80% of taxable income. Our NOLs generated in 2017 and in prior years will
not be subject to the 80% limitation under the Tax Act. In addition, we had state net operating loss carryforwards totaling approximately $332.7 million,
which are available to offset future state taxable income. The state net operating loss carryforwards are inclusive of North Carolina net operating losses,
which are recorded at zero benefit, as discussed in the income tax footnote. State net operating losses begin to expire in 2024. Because we had incurred
cumulative  net  operating  losses  since  inception,  all  tax  years  remain  open  to  examination  by  U.S.  federal  and  state  income  tax  authorities.  As  of
December 31, 2021, we also had federal research and development (R&D) credit carryforwards of approximately $17.0 million available to offset future
income tax which begin to expire in 2035.

Our ability to utilize net operating losses and research and development credit carryforwards may be substantially limited due to ownership changes that
may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the Code), as well as
similar  state  provisions.  These  ownership  changes  may  limit  the  amount  of  NOL  and  R&D  credit  carryforwards  that  can  be  utilized  annually  to  offset
future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series
of  transactions  over  a  three-year  period  resulting  in  an  ownership  change  of  more  than  50  percent  of  the  outstanding  stock  of  a  company  by  certain
stockholders or public groups.

In  April  2019,  we  completed  an  evaluation  study  as  to  whether  an  “ownership  change”  had  occurred  and  determined  that  the  limitation  would  be
approximately $8.0 million on federal net operating loss carryforwards, $1.2 million on state net operating loss carryforwards, and $0.1 million on R&D
tax credit carryforwards. The carryforward amounts reported above have already been reduced for these limitations. We continue to maintain a valuation
allowance on the remaining NOLs and tax credits as we believe that it is more likely than not that all of the deferred tax asset associated with them will not
be realized regardless of whether an “ownership change” has occurred.

Product sales, net

Product sales, net was $11.1 million and $0 for the years ended December 31, 2021 and December 31, 2020, respectively. The sales revenue recognized in
the current year was related to the product sales of COSELA. We received FDA approval of COSELA on February 12, 2021 and the product has been
commercially available since March 2, 2021.

License revenue

License  revenue  was  $20.4  million  and  $45.3  million  for  the  years  ended  December  31,  2021  and  December  31,  2020,  respectively.  License  revenue
recognized in the current year was primarily related to $11.0 million in milestone payments from Genor and Simcere. We also recognized $2.5 million and
$1.0  million  in  clinical  trial  costs  reimbursed  by  EQRx  and  Simcere,  respectively.  Additionally,  we  recognized  $5.9  million  in  supply,  manufacturing
services  and  patent  reimbursable  costs  from  EQRx,  Genor,  and  Simcere.  License  revenue  recognized  in  the  prior  year  was  primarily  related  to  $42.1
million in revenue recognized from the Simcere, EQRx, Genor and ARC upfront payments under the respective license agreements following the transfer
of related technology and know-how which occurred during the period. We also recognized $1.3 million for clinical trial costs reimbursed by EQRx and
$0.4 million in patent costs to be reimbursed by EQRx, Genor, and Simcere. Additionally, we recognized $1.3 million in revenue for existing inventory
transfers to EQRx and Genor which occurred during the fourth quarter of 2020.

Cost of goods sold

Cost of goods sold was $2.0 million and $0 for the years ended December 31, 2021 and December 31, 2020, respectively. Cost of goods sold includes our
third-party logistics costs for the sales of COSELA, inventory overhead costs, and personnel costs.

Research  and  development  expenses  were  $76.2  million  for  the  year  ended  December  31,  2021  as  compared  to  $73.3  million  for  the  year  ended
December  31,  2020.  The  increase  of  $2.9  million,  or  4%,  was  primarily  due  to  an  increase  of  $20.0  million  in  our  clinical  program  costs,  offset  by  a
decrease  of  $16.2  million  for  manufacturing  of  active  pharmaceutical  ingredient  and  drug  product  to  support  our  clinical  trials  and  a  decrease  of  $0.9
million  in  external  costs  related  to  discovery  and  preclinical  development.  The  following  table  summarizes  our  research  and  development  expenses
allocated to trilaciclib, rintodestrant, lerociclib, and unallocated research and development expenses for the periods indicated:

December 31, 2020. The increase of $27.2 million, or 40%, was due to an increase of $12.7 million in personnel related costs due to increased headcount,
of which $5.4 million related to non-cash stock compensation expense, an increase of $12.1 million in commercialization activities, an increase of $2.2 in
information  technology  systems  and  related  expenses,  and  an  increase  of  $0.2  million  medical  affairs  costs  related  to  trilaciclib,  professional  services,
insurance, and other administrative costs.

Total other income (expense), net

Total other income (expense), net was $(5.0) million for the year ended December 31, 2021 as compared to $(1.4) million for the year ended December 31,
2020. The decrease of $3.6 million, or -263%, was primarily driven and increase in interest expense on loan payable due to higher principal balance in
2021 as compared to 2020.

Income tax expense

Income  tax  expense  was  $0.9  million  for  the  year  ended  December  31,  2021  as  compared  to  $1.4  million  for  the  year  ended  December  31,  2020.  The
decrease of $0.5 million, or -34%, in foreign withhold taxes incurred is a result of a decrease in license revenue recognized from Simcere as compared to
the prior.

Product sales, net

Product sales, net was $0 for each of the years ended December 31, 2020 and December 31, 2019.

License revenue

License revenue was $45.3 million and $0 for the years ended December 31, 2020 and December 31, 2019, respectively. The license revenue for the year
ended December 31, 2020 was primarily related to $42.1 million in revenue recognized from the Simcere, EQRx, Genor and ARC upfront payments under
the respective license agreements following the transfer of the related technology and know-how which occurred during the period. We also recognized
$1.3  million  for  clinical  trial  costs  and  $0.4  million  in  patent  costs  to  be  reimbursed  by  EQRx,  Genor,  and  Simcere.  Additionally,  we  recognized  $1.3
million in revenue for existing inventory transfers to EQRx and Genor which occurred during the fourth quarter of 2020.

Cost of goods sold

Cost of goods sold was $0 for each of the years ended December 31, 2020 and December 31, 2019.

Research and development

Research  and  development  expenses  were  $73.3  million  for  the  year  ended  December  31,  2020  as  compared  to  $89.0  million  for  the  year  ended
December  31,  2019.  The  decrease  of  $15.7  million,  or  -18%,  was  primarily  due  to  a  decrease  of  $10.2  million  in  our  clinical  program  costs  due  to  a
decrease in spend for ongoing clinical trials of $5.7 million and decrease of $5.9 million related to a regulatory filing expense of $2.9 million incurred in
2019 and reimbursed in 2020, partially offset by an increase in personnel costs of $1.4 million. The decrease of $1.3 million in costs for manufacturing of
active pharmaceutical ingredient and drug product to support our clinical trials, as well as a decrease in research and development expenses was also due to
a  decrease  of  $4.2  million  in  external  costs  related  to  discovery  and  preclinical  development.  The  following  table  summarizes  our  research  and
development expenses allocated to trilaciclib, rintodestrant, lerociclib, and unallocated research and development expenses for the periods indicated:

Selling, general and administrative

Selling, general and administrative expenses were $68.5 million for the year ended December 31, 2020 as compared to $40.0 million for the year ended
December 31, 2019. The increase of $28.5 million, or 71%, was due to an increase of $6.8 million in personnel related costs due to increased headcount, of
which $1.7 million related to non-cash stock compensation expense, an increase of $15.8 million in expenses related to pre-commercialization activities, an
increase of $2.0 million in medical affairs costs related to trilaciclib, an increase of $0.8 million in information technology systems and related expenses,
and an increase of $3.1 million professional services, insurance, and other administrative costs.

Total other income (expense), net

Total other income (expense), net was $(1.4) million for the year ended December 31, 2020 as compared to $6.6 million for the year ended December 31,
2019. The decrease of $8.0 million was primarily driven by a lower balance of money market funds due to cash used in operating activities and changes in
interest rates during the year ended December 31, 2020 as compared to the year ended December 31, 2019, interest expense on loan payable, and loss on
disposal of fixed assets.

Income tax expense

Income  tax  expense  was  $1.4  million  and  $0  for  the  year  ended  December  31,  2020  and  December  31,  2019,  respectively.  The  income  tax  expense
recognized in the year ended December 31, 2020 related to the foreign withholding taxes incurred as a result of the upfront payment received from the
Simcere license agreement entered into in 2020.

Liquidity and Capital Resources   

We have incurred cumulative losses and negative cash flows from operations since our inception in 2008. We incurred net losses of $148.4 million for the
year ended December 31, 2021, $99.3 million for the year ended December 31, 2020, and $122.4 million for the year ended December 31, 2019. As of
December 31, 2021, we had an accumulated deficit of $584.5 million. 

As of December 31, 2021, we had cash and cash equivalents of $221.2 million. To date, we have funded our operations primarily through proceeds from
our initial public offering, our follow-on stock offerings, our debt agreement with Hercules Capital, and proceeds from our license agreements. Under our
licensing arrangements, we are eligible to receive certain development and sales-based milestones. Our ability to earn these milestones and the timing of
achieving these milestones is primarily dependent upon the outcome of the licensee’s activities and are uncertain at this time.

Shelf registration statement

On July 2, 2021, we filed an automatically effective shelf registration statement with the Securities and Exchange Commission  (the “SEC”), which we
refer to as the 2021 Form S-3.  Each issuance under the shelf registration statement would have required the filing of a prospectus supplement identifying
the amount and terms of securities to be issued.  The 2021 Form S-3 did not limit the amount of securities that could have been issued thereunder.

On February 23, 2022, because we are no longer a “well-known seasoned issuer” as such term is defined in Rule 405 under the Securities Act of 1933, as
amended, we filed an automatic post-effective amendment to the 2021 Form S-3 on Form POSASR, which became effective upon filing, to register for sale
up to $300.0 million of any combination of our common stock, preferred stock, debt securities, warrants, rights and/or units from time to time and at prices
and on terms that we may determine and, as required by SEC rules, will file another post-effective amendment to the 2021 Form S-3 on Form POS AM
after the filing of this Form 10-K. Once the post-effective amendment to the 2021 Form S-3 on Form POS AM has been declared effective by the SEC, the
2021 Form S-3 will remain in effect for up to three years from the date it originally became effective, which was July 2, 2021. We make no assurances as to
our ability to continue to use the 2021 Form S-3.

At-the-market offerings

On June 15, 2018, we entered into a sales agreement for “at the market offerings” with Cowen and Company, LLC (“Cowen”), which allows us to issue
and sell shares of common stock pursuant to a shelf registration statement for total gross sales proceeds of up to $125.0 million from time to time through
Cowen, acting as our agent. Between June 18, 2018 and August 2, 2018, we sold 752,008 shares of common stock pursuant to this agreement resulting in
$36.1 million in net proceeds, realizing $12.1 million in the second quarter and the remaining $24.0 million by August 2, 2018.

Between January 14, 2021 and February 9, 2021, we sold 3,513,027 shares of common stock pursuant to this agreement resulting in $86.4 million in net
proceeds. As of February 9, 2021, we have used the entirety of the remaining availability under the sales agreement with Cowen.

In connection with the 2021 Form S-3, on July 2, 2021, we entered into a sales agreement for “at the market offerings” with Cowen, which allowed us to
issue and sell shares of common stock pursuant to the 2021 Form S-3 for total gross sales proceeds of up to $150.0 million from time to time through
Cowen, acting as our agent (the “2021 Sales Agreement”). We did not sell any shares of common stock or other securities under the 2021 Sales Agreement
and we terminated the 2021 Sales Agreement on February 23, 2022. Also, on February 23, 2022, we entered into the 2022 Sales Agreement for “at the
market offerings” with Cowen, which allows us to issue and sell shares of common stock pursuant to the 2021 Form S-3, once it has been post-effectively
amended as noted above, for total gross sales proceeds of up to $100.0 million from time to time through Cowen, acting as our agent.

Loan and Security Agreement with Hercules

On May 29, 2020, we entered into a loan and security agreement with Hercules Capital, Inc. (“Hercules”) under which Hercules has agreed to lend us up to
$100.0 million, to be made available in a series of tranches, subject to specified conditions. We borrowed $20.0 million at loan closing. The term of the
loan is approximately 48 months, with a maturity date of June 1, 2024. No principal payments are due during an interest-only period, commencing on the
initial borrowing date and continuing through June 1, 2022. The interest only period may be extended through January 1, 2023 upon satisfaction of certain
milestones. Following the interest only period, we will repay the principal balance and interest of the advances in equal monthly installments through June
1, 2024.

On March 31, 2021, we entered into the First Amendment to Loan and Security Agreement (the “First Amendment”) with Hercules whereby the Company
drew the remaining $10.0 million of the first tranche and the interest rate and financial covenants were amended. Unless loan advances exceeded $40.0
million, no financial covenants were required.

On November 1, 2021, we entered into a Second Amendment to the loan and security agreement with Hercules under which Hercules has agreed to lend us
up to $150.0 million, to be made available in a series of tranches, subject to certain terms and conditions. The first tranche was increased to $100.0 million.
At  close  of  the  Second  Amendment,  we  borrowed  an  additional  $45.0  million  from  Tranche  1  with  $25.0  million  remaining  to  be  borrowed  through
September 15, 2022. No principal payments are due during an interest-only period, commencing on the close of the Second Amendment and continuing
through  December  1,  2024.  The  interest  only  period  may  be  extended  through  December  1,  2025,  in  quarterly  increments,  subject  to  compliance  with
covenants of the Second Amendment. Following the interest only period, we will repay the principal balance and interest of the advances in equal monthly
installments through the maturity date of November 1, 2026.

Net cash used in investing activities

For the year ended December 31, 2021 there was no cash provided or used in investing activities.

Net cash used in investing activities was $0.2 million for the year ended December 31, 2020, which represented proceeds from the disposal of property and
equipment.

Net  cash  used  in  investing  activities  was  $2.7  million  for  the  year  ended  December  31,  2019,  which  represented  purchases  of  property  and  equipment,
primarily associated with laboratory equipment and leasehold improvements for new office space.

Net cash provided by financing activities

During the year ended December 31, 2021, net cash provided by financing activities was $145.9 million, which consisted of $86.4 million in net proceeds
from  our  ATM  offering  after  deducting  cash  paid  during  the  year  for  underwriting  discounts  and  commissions  and  other  expenses,  $55.0  million  in
proceeds  from  our  loan  agreement  with  Hercules,  partially  offset  by  $1.4  million  in  payments  related  to  debt  issuances  costs,  and  $5.9  million  in  net

to debt issuances costs.

During the year ended December 31, 2019, net cash provided by financing activities was $2.7 million in net proceeds from the exercise of stock options.

Operating capital requirements and plan of operations

To date, we have generated limited revenue from product sales. We expect our expenses to increase as we continue the development of and seek additional
regulatory approvals for trilaciclib, and continue to commercialize COSELA. We are subject to all of the risks inherent in the development of new products,
and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business.

We believe that our existing cash and cash equivalents will be sufficient to fund our projected cash needs for greater than 12 months following the filing of
this Annual Report.

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all of our available capital
resources  sooner  than  we  expect.  Because  of  the  numerous  risks  and  uncertainties  associated  with  research,  development  and  commercialization  of
pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on
many factors, including, but not limited to:

•

•

•

•

•

•

•

the scope, progress, results and costs of nonclinical development, laboratory testing and clinical trials for our product candidates;

the scope, prioritization and number of our research and development programs;

the costs, timing and outcome of regulatory review of our product candidates;

the extent to which we enter into non-exclusive, jointly funded clinical research collaboration arrangements, if any, for the development of
our product candidates in combination with other companies’ products;

our ability to establish such collaborative co-development arrangements on favorable terms, if at all;

the achievement of milestones or occurrence of other developments that trigger payments under our license agreement and any collaboration
agreements into which we enter;

the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical trial costs under future collaboration agreements, if
any;

84

 
 
 
 
 
 
 
 
 
 
•

•

•

•

the extent to which we acquire or in-license product candidates and technologies, such as rintodestrant, and the terms of such in-licenses;

the  costs  of  commercialization  activities,  including  product  sales,  marketing,  manufacturing  and  distribution,  for  any  of  our  product
candidates for which we receive marketing approval;

revenue received from commercial sales of our product candidates; and

the  costs  of  preparing,  filing  and  prosecuting  patent  applications,  maintaining  and  enforcing  our  intellectual  property  rights  and  defending
intellectual property-related claims.

Until  such  time,  if  ever,  as  we  can  generate  substantial  revenues,  we  expect  to  finance  our  cash  needs  through  a  combination  of  equity  offerings,  debt
financings, other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. We do
not have any committed external source of funds except for amounts included under our licensing arrangements and the loan agreement with Hercules. To the
extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interest will be diluted, and the
terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing, if available,
may  involve  agreements  that  include  covenants  limiting  or  restricting  our  ability  to  take  specific  actions,  such  as  incurring  additional  debt,  making  capital
expenditures or declaring dividends. If we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may
have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may
not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, limit, reduce or terminate our product development
or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations, Commitments and Contingencies

Represents  future  minimum  lease  payments  under  the  non-cancelable  lease  for  our  headquarters  in  Research  Triangle  Park,  NC  and  our  former
headquarters in Research Triangle Park, NC. The lease for the new office space commenced in September 2019 for approximately 60,000 square
feet of laboratory space and office space in Research Triangle Park, NC. The lease will expire in September 2027, with the Company having the
option to renew for an additional 5 years. The lease for our former headquarters will expire in December 2022. The minimum lease payments above
do not include any related common area maintenance charges or real estate taxes.

Amounts  in  the  table  reflect  payments  due  for  our  Second  Amendment  to  the  Loan  and  Security  Agreement  with  Hercules  with  outstanding
borrowings of $75.0 million as of December 31, 2021. The amounts in the table above reflect interest-only payments through December 1, 2024
with payments on principal beginning thereafter. For purposes of the table above, interest payments were calculated using an annual interest rate of
9.15%, which was the interest rate in effect as of December 31, 2021. Additionally, the table above includes end of term charges of $2.1 million due
on  June  1,  2025  and  $5.1  million  due  upon  maturity  on  November  1,  2026.  See  Note  8  of  the  financial  statements  for  further  discussion  of
the Hercules loan agreement.

(3) We  enter  into  agreements  in  the  normal  course  of  business  with  contract  research  organizations  (CROs)  for  clinical  trials  and  with  vendors  for
preclinical studies and other services and products for operating purposes which are cancelable at any time by us, generally upon 30-60 days prior
written notice. As of December 31, 2021, we have several on-going clinical studies in various stages. Under agreements with various CROs and
clinical study sites, we incur expenses related to clinical studies of our product candidates and potential other clinical candidates. The timing and
amounts of these disbursements are contingent upon the services rendered or as expenses are incurred by the CROs or clinical trial sites. Therefore,
we cannot estimate the potential timing and amount of these payments and they have been excluded from the table above. Also, the above amounts
exclude potential payments to be made under our license agreement for rintodestrant with the University of Illinois that are based on the progress of
rintodestrant, as these payments are not determinable.

(4) We entered into a Product Agreement with Patheon Manufacturing Services, LLC as issued under the Master Manufacturing Services Agreement
dated  August  27,  2019  to  manufacture  and  supply  trilaciclib  for  commercial  production.  The  initial  term  of  the  agreement  is  effective  until
December 31, 2024. If the annual volume of product ordered does not meet a specified amount, a true-up payment to this minimum will be due at
the end of the applicable year. This minimum purchase amount was excluded from the table above as the conditions of the committed amount make
it undeterminable at this time.

(5) We entered into a three-year co-promotion agreement in the United States and Puerto Rico with Boehringer Ingelheim Pharmaceuticals, Inc., or BI,
in June 2020. In December 2021, G1 and BI announced that the parties mutually agreed to end the co-promotion agreement for COSELA, effective
March 2022. At that time, we announced that we would hire and deploy a total of 34 oncology sales representatives to accelerate sales activities and
help  maximize  the  adoption  of  COSELA.  For  two  years  following  the  termination,  sales  payments  to  BI  will  be  decreased  to  mid-single  digit
percentages of net sales. The sales payments will vary based on the level of net sales in an applicable year following the termination. Our obligations
to make sales payments under the co-promotion agreement will terminate in March 2024.

Off-Balance Sheet Arrangements

We did not have, during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable SEC rules.

Recent Accounting Pronouncements

See Note 2 to our financial statements included elsewhere in this report regarding the impact of certain recent accounting pronouncements on our financial
statements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We  are  exposed  to  market  risks  in  the  ordinary  course  of  our  business.  These  risks  primarily  include  interest  rate  sensitivities.  We  had  cash  and  cash
equivalents  of  $221.2  million  as  of  December  31,  2021,  which  consists  of  deposits  in  banks,  including  checking  accounts,  money  market  accounts  and
certificates of deposit. Such interest-earning instruments carry a degree of interest rate risk; however, historical fluctuations in interest income have not
been significant.

We also have exposure to market risk on our loan agreement with Hercules Capital, Inc. Our loan agreement accrues interest from its date of issue at a
variable  interest  rate  equal  to  the  greater  of  either  (i)  (a)  the  prime  rate  as  reported  in  The  Wall  Street  Journal,  plus  (b)  5.90%,  and  (ii)  9.15%.  As  of
December 31, 2021, $75.0 million was outstanding under the loan agreement with Hercules.

We are not currently exposed to significant market risk related to changes in foreign currency exchange rates; however, our operations may be subject to
fluctuations in foreign currency exchange rates in the future.

Inflation generally affects us by increasing our cost of labor. We do not believe that inflation had a material effect on our business financial condition or
results of operations three and twelve months ended December 31, 2021.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit
under the Securities and Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and
forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely
decisions regarding required disclosure.

As  of  December  31,  2021,  our  management,  with  the  participation  of  our  principal  executive  officer  and  principal  financial  officer,  evaluated  the
effectiveness  of  our  disclosure  controls  and  procedures  (as  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Securities  Exchange  Act  of  1934).  Our
management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving
their  objectives,  and  management  necessarily  applies  its  judgement  in  evaluating  the  cost-benefit  relationship  of  possible  controls  and  procedures.    Our
principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of December 31, 2021, our
disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Controls Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during 2021 that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act
Rule 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief
Financial  Officer,  we  conducted  an  evaluation  of  the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the  framework  in  Internal
Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  Based  on  our
evaluation under the framework in Internal Control—Integrated Framework, our management concluded that our internal control over financial reporting
was effective as of December 31, 2021.

The  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2021,  has  been  audited  by  PricewaterhouseCoopers  LLP,  an
independent registered public accounting firm, as stated in their report, which is included in this Annual Report on Form 10-K.

Item 9B. Other Information.

“At the Market” Offering

On February 23, 2022, we entered into a sales agreement (the “2022 Sales Agreement”) with Cowen and Company, LLC (“Cowen”) with respect to an at-
the-market offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, par value $0.0001
per share (the “Common Stock”), having an aggregate offering price of up to $100.0 million (the “Placement Shares”) through Cowen as our sales agent.
Our issuance and sale, if any, of the Placement Shares under the 2022 Sales Agreement is subject to the effectiveness of a post-effective amendment to our
registration statement on Form S-3 (File No. 333-257640), to be filed with the Securities and Exchange Commission after the filing of this Form 10-K on
February 23, 2022. We make no assurances as to if or when the registration statement, as post-effectively amended, will become effective or, if it does
become effective, as to the continued effectiveness of the registration statement.  

We  are  not  obligated  to  make  any  sales  of  Common  Stock  under  the  2022  Sales  Agreement.  The  offering  of  Placement  Shares  pursuant  to  the
2022 Sales Agreement will terminate upon the earlier of (i) the sale of all Placement Shares subject to the 2022 Sales Agreement or (ii) termination of the
2022 Sales Agreement in accordance with its terms.  

Upon delivery of a placement notice and subject to the terms and conditions of the 2022 Sales Agreement, Cowen may sell the Placement Shares by any
method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act of 1933, as amended, including, without
limitation,  sales  made  through  The  Nasdaq  Global  Select  Market  or  on  any  other  existing  trading  market  for  the  Common  Stock.  Cowen  will  use
commercially reasonable efforts to sell the Placement Shares from time to time, based upon our instructions (including any price, time or size limits or
other customary parameters or conditions we may impose). We will pay Cowen a commission equal to three percent (3%) of the gross sales proceeds of
any Placement Shares sold

87

 
 
 
through Cowen under the 2022 Sales Agreement, and we also have provided Cowen with customary indemnification and contribution rights.

The  foregoing  description  of  the  2022  Sales Agreement  is  qualified  in  its  entirety  by  reference  to  the  full  text  of  the  2022  Sales Agreement,  which  is
attached hereto as Exhibit 10.92 and incorporated herein by reference. The legal opinion of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. relating to
the shares of common stock being offered pursuant to the 2022 Sales Agreement is filed as Exhibit 5.1 to the Company’s Form POSASR filed February 23,
2022.  

In connection with our entering into the 2022 Sales Agreement with Cowen, on February 23, 2022, we terminated that certain sales agreement, dated as of
July 2, 2021 (the “2021 Sales Agreement”), that we previously entered into with Cowen with respect to an at-the-market offering program, under which we
could offer and sell, from time to time at our sole discretion, shares of our Common Stock having an aggregate offering price of up to $150.0 million (the
“2021 ATM Program”). As the date hereof, we had not sold any shares of common stock or other securities pursuant to the 2021 ATM Program. As a result
of the termination of the 2021 Sales Agreement, we will not offer or sell any additional shares under the 2021 ATM Program.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of G1 Therapeutics, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying balance sheets of G1 Therapeutics, Inc. (the “Company”) as of December 31, 2021 and 2020, and the related statements
of operations, of redeemable convertible preferred stock and stockholders' equity (deficit) and of cash flows for each of the three years in the period ended
December 31, 2021, including the related notes (collectively referred to as the “financial statements”). We also have audited the Company's internal control
over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee
of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31,
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
accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective
internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by
the COSO.

Basis for Opinions

The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its
assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting
appearing under Item 9A. Our responsibility is to express opinions on the Company’s financial statements and on the Company's internal control over
financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States)
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control
over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due
to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the
design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we
considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or
required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the financial statements and (ii)
involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion
on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical
audit matter or on the accounts or disclosures to which it relates.

Accrued External Clinical Study Costs

As described in Notes 2 and 6 to the financial statements, management estimated and accrued research and development expenses including external
clinical study costs associated with clinical trial activities. The Company’s accrued external clinical study costs were $9.6 million as of December 31, 2021.
The process of estimating and accruing expenses involved reviewing contracts and purchase orders, identifying services that have been provided on the
Company’s behalf, and estimating the level of service performed and the associated cost incurred for the service when the Company has not yet been
invoiced or otherwise notified of the actual cost. Costs for clinical trial activities were estimated based on an evaluation of the vendors’ progress towards
completion of specific tasks, using data such as patient enrollment, clinical site activations or information provided by vendors regarding their actual costs
incurred. Management determined accrual estimates through reports from and discussion with applicable personnel and outside service providers as to the
progress or state of completion of trials, or the services completed.

The principal considerations for our determination that performing procedures relating to accrued external clinical study costs is a critical audit matter are
the significant judgment by management in estimating the costs incurred to date, specifically progress towards completion of specific tasks. This in turn led
to a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence relating to cost estimates made by
management to establish accrued external clinical study costs.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the financial
statements. These procedures included testing the effectiveness of controls relating to the completeness and accuracy of accrued external clinical study
costs. These procedures also included, among others, (i) testing management’s process for estimating accrued external clinical study costs, (ii) evaluating
the appropriateness of the method used by management to develop the estimate, (iii) evaluating the reasonableness of significant assumptions, including
progress towards completion of specific tasks and the associated cost incurred for services when the Company has not yet been invoiced or otherwise
notified of the actual cost, and (iv) testing the completeness and accuracy of underlying data used in the model.

Notes to Financial Statements

1. Description of Business

G1 Therapeutics, Inc. (the “Company”) is a commercial-stage biopharmaceutical company based in Research Triangle Park, North Carolina focused on the
development and commercialization of novel small molecule therapeutics for the treatment of patients with cancer. The Company’s first FDA-approved
product, COSELA™ (trilaciclib) is the first and only therapy indicated to proactively help protect bone marrow from the damage of chemotherapy and is
first innovation in managing myelosuppression in decades. The Company was incorporated on May 19, 2008 in the state of Delaware.

The Company uses “COSELA” when referring to its FDA approved drug and “trilaciclib” when referring to the development of COSELA for additional
indications.  

The Company is advancing trilaciclib, a first-in-class therapy designed to improve outcomes for patients who are treated with chemotherapy, in clinical
trials  assessing  myeloprotection  and  anti-tumor  efficacy  endpoints  in  a  variety  of  tumors  including  colorectal  cancer  (“CRC”),  breast  cancer,  bladder
cancer, and in trials designed to inform the design of future additional pivotal studies across multiple tumor types and treatment combinations including
targeted chemotherapy medicines called antibody-drug conjugates (“ADCs”).

The Company’s clinical approach to designing our clinical program includes monitoring the evolution of future standards of care and develop trilaciclib
with these in mind, allowing it to conduct or support trials that will generate important data to maximize future usage in a variety of future settings. The
Company’s robust clinical pipeline includes the following ongoing trials:

•
•
•
•
•

Phase 3 trial in colorectal cancer (initial results including myeloprotection and ORR endpoints expected in 1Q2023)
Phase 3 trial in 1L mTNBC (initial results including interim results for OS expected in 2H2023
Phase 2 trial in bladder cancer (initial results including ORR and myeloprotection endpoints expected in 4Q2022)
Phase 2 trial in combination with the ADC Trodelvy (initial results including ORR and myeloprotection endpoints expected in 4Q2022)
Phase  2  trial  to  confirm  the  immune-based  mechanism  of  action  (MOA)  of  trilaciclib  in  early-stage  neoadjuvant  TNBC  (initial  results
including immune endpoints (e.g., CD8+ / Treg ratio) expected in 4Q2022)

The Company is also conducting extensive preclinical development work to assess the synergistic potential of trilaciclib with a variety of new anti-cancer
mechanisms.

The Company also has a robust Investigator Initiated Studies (“ISS”) program. An ISS is a study that is developed and conducted by a qualified physician
external to the Company who assumes full responsibility for the conduct of the study. The Company supports investigator sponsored studies that align with
its areas of scientific interest. The Company anticipates that the first ISS to be supported by G1 will be in 1L NSCLC and expect it to be initiated in the first
half of 2022.

The Company out-licensed global rights to lerociclib, an internally discovered and differentiated oral CDK4/6 inhibitor designed to enable more effective
combination  treatment  strategies  across  multiple  oncology  indications.  In  addition,  the  company  out-licensed  global  rights  to  an  internally  discovered
CDK2  inhibitor  for  all  human  and  veterinary  uses.  The  Company  is  in  the  process  of  evaluating  partnering  options  for  rintodestrant,  an  oral  selective
estrogen receptor degrader (SERD) for the potential treatment of ER+, HER2- breast cancer. The Company also has intellectual property focused on cyclin-
dependent kinase targets.

Trilaciclib

The  Company’s  lead  compound,  COSELA™  (trilaciclib),  is  a  first-in-class  therapy  approved  to  help  protect  hematopoietic  stem  and  progenitor  cells
(“HSPCs”) in bone marrow against chemotherapy-induced myelosuppression by transiently inhibiting CDK4/6 in patients with extensive-stage small cell
lunger cancer (“ES-SCLC”). This action leads to temporary arrest of susceptible host cells during chemotherapy. This reduces the duration and severity of
neutropenia and other myelosuppressive consequences of chemotherapy.

Trilaciclib is a novel therapeutic approach, which is given before chemotherapy, that temporarily blocks progression through the cell cycle. Its short half-
life and IV route of administration allows for rapid onset, controlled administration, and clean G1 arrest, which are important attributes required for its
unique  mechanism  of  action.  Transient  IV  CDK4/6  inhibition  with  trilaciclib  provides  two  benefits.  First,  it  proactively  helps  protect  HSPCs  in  bone
marrow  leading  to  preservation  of  neutrophils,  erythrocytes,  and  platelets  (called  myeloprotection)  which  reduces  the  occurrences  and  severity  of
neutropenia  and  other  myelosuppressive  consequences  of  chemotherapy.  This  myeloprotection  benefit  has  been  conclusively  proven  in  double-blind
placebo-controlled clinical trials in

F-7

 
 
 
 
 
 
 
 
extensive-stage small cell lung cancer. Second, clinical data has shown that trilaciclib has the potential to activate and enhance the immune system response
driving increased anti-tumor efficacy, which we are exploring in clinical trials in a variety of solid tumor types and treatment settings.

On February 12, 2021, COSELA (trilaciclib) for injection was approved by the U.S. Food and Drug Administration (“FDA”) to decrease the incidence of
chemotherapy-induced  myelosuppression  in  adult  patients  when  administered  prior  to  a  platinum/etoposide-containing  regimen  or  topotecan-containing
regimen for ES-SCLC. On March 2, 2021, COSELA became commercially available through the Company’s specialty distributor network. COSELA is
administered  intravenously  as  a  30-minute  infusion  completed  within  four  (4)  hours  prior  to  the  start  of  chemotherapy  and  is  the  first  FDA-approved
therapy to provide proactive, multilineage protection from chemotherapy-induced myelosuppression. The approval of COSELA is based on data from three
(3)  randomized,  placebo-controlled  trials  that  showed  patients  receiving  COSELA  prior  to  chemotherapy  had  clinically  meaningful  and  statistically
significant reduction in the duration and severity of neutropenia, reduction of red blood cell transfusions, as well as improvements in other myeloprotection
measures, compared to patients receiving chemotherapy without COSELA. The Company announced on March 25, 2021 that COSELA had been included
in  two  updated  National  Comprehensive  Cancer  Network®  (“NCCN”)  Clinical  Practice  Guidelines  in  Oncology  (NCCN  Guidelines®):  The  Treatment
Guidelines for Small Cell Lung Cancer and the Supportive Care Guidelines for Hematopoietic Growth Factors. These guidelines document evidence-based,
consensus-driven management to ensure that all patients receive preventive, diagnostic, treatment, and supportive services that are most likely to lead to
optimal outcomes. On October 1, 2021, the Company announced that the permanent J-code for COSELA that was issued in July 2021 by the Centers for
Medicare & Medicaid Services (CMS) is now effective for provider billing for all sites of care. All hospital outpatient departments, ambulatory surgery
centers and physician offices in the United States have one consistent Healthcare Common Procedure Coding System (HCPCS) code to standardize the
submission and payment of COSELA insurance claims across Medicare, Medicare Advantage, Medicaid and commercial plans. G1’s new technology add-
on payment (NTAP) for COSELA which provides additional payment to inpatient hospitals above the standard Medicare Severity Diagnosis-Related Group
(MS-DRG) payment amount also became effective for provider billing on October 1, 2021.

In  June  2020,  we  entered  into  a  three-year  co-promotion  agreement  for  COSELA  in  the  United  States  and  Puerto  Rico  with  Boehringer  Ingelheim
Pharmaceuticals, Inc. (“BI”). In December 2021, G1 and BI mutually agreed to end the co-promotion agreement for COSELA, effective March 2022. At
that time, the Company announced that it would hire and deploy a total of 34 oncology sales representatives to allow G1 to target all accounts to accelerate
sales activities and help maximize the adoption of COSELA. As of February 21, 2022, all 34 sales representatives have been hired, trained and deployed.

In  August  2020,  the  Company  entered  into  an  exclusive  license  agreement  with  Nanjing  Simcere  Dongyuan  Pharmaceutical  Co.,  Ltd  (“Simcere”)  for
development and commercialization rights for trilaciclib in all indications in Greater China (mainland China, Hong Kong, Macau and Taiwan). Under the
terms of the agreement, the Company received an upfront payment of $14.0 million in September 2020 and will be eligible to receive up to $156.0 million
in  development  and  commercial  milestone  payments.  During  the  twelve  months  ended  December  31,  2021,  the  Company  received  three  development
milestone payments totaling $8.0 million. Simcere will also pay the Company tiered low double-digit royalties on annual net sales of trilaciclib in Greater
China. As part of this agreement, Simcere will participate in global clinical trials of trilaciclib and the companies will be responsible for all development
and commercialization costs in their respective territories.

The  Company  is  also  executing  on  our  tumor-agnostic  strategy  to  evaluate  the  potential  benefits  of  trilaciclib  to  patients  with  other  tumors  and  to
continuously develop new data with trilaciclib in a variety of chemotherapeutic settings and in combination with other agents to maximize the applicability
of the drug to potential future treatment paradigms.

Lerociclib

Lerociclib is a differentiated clinical-stage oral CDK4/6 inhibitor for use in combination with other targeted therapies in multiple oncology indications. In
2020, the Company entered into separate, exclusive agreements with EQRx, Inc. (rights for U.S., Europe, Japan and all markets outside Asia-Pacific) and
Genor Biopharma Co. Inc. (rights for Asia-Pacific, excluding Japan) for the development and commercialization of lerociclib in all indications. Combined,
these agreements provide $26.0 million in upfront payments to the Company, and the opportunity for up to $330.0 million in potential milestone payments,
plus sales-based royalties. EQRx, Inc. and Genor Biopharma Co. Inc. are responsible for all costs related to the development and commercialization of
lerociclib in their respective territories.

Rintodestrant

Rintodestrant  is  an  oral  SERD  for  the  treatment  of  estrogen  receptor-positive  (“ER+”)  breast  cancer.  The  Company  is  in  the  process  of  evaluating
partnering options for rintodestrant.

CDK2 Inhibitor

In 2020, we entered into a global license agreement with ARC Therapeutics, LLC for the development and commercialization of an internally discovered
CDK2 inhibitor for all human and veterinary uses. ARC is currently granted an exclusive, royalty-bearing, license with the right to grant sublicenses to one
of our solely owned patent families.

The Company’s financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization
of assets and the settlement of liabilities and commitments in the normal course of business. As of December 31, 2021, the Company had an accumulated
deficit of $584.5 million. The Company has reported a net loss in all fiscal periods since inception and expects to incur substantial losses in the future to
conduct research and development and pre-commercialization activities.

As  of  December  31,  2021,  the  Company  had  cash  and  cash  equivalents  of  $221.2  million.      The  Company  expects  that  its  existing  cash  and  cash
equivalents will enable it to fund its operating expenses and capital expenditure requirements for greater than 12 months from the date of filing this Annual
Report.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The  Company  has  prepared  the  accompanying  financial  statements  in  conformity  with  generally  accepted  accounting  principles  in  the  United  States  of
America (“U.S. GAAP”).

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts
reported in the financial statements and the accompanying notes. On an ongoing basis, the Company’s management evaluates its estimates which include,
but  are  not  limited  to,  estimates  related  to  accrued  expenses,  accrued  external  clinical  costs,  net  product  sales,  stock-based  compensation  expense  and
deferred tax asset valuation allowance. Actual results could differ from those estimates. These estimates include the Company’s common stock valuation,
stock compensation, and deferred tax asset valuation allowance.

Accounts Receivable

The Company’s accounts receivable consists of amounts due from specialty distributors in the U.S. (collectively, its “Customers”) related to sales of
COSELA and have standard payment terms. Trade receivables are recorded net of the estimated variable consideration for chargebacks based on
contractual terms and the Company’s expectation regarding the utilization and earnings of the chargebacks and discounts as well as the net amount
expected to be collected from the Company’s customers. Estimates of the Company’s credit losses are determined based on existing contractual payment
terms, individual customer circumstances, and any changes to the economic environment.

In addition, the Company’s accounts receivable consists of open invoices issued to its license partners for services rendered by the Company or receivables
with its license partners for invoices related to milestones that were completed and recognized as revenue.

Inventories

Inventories are stated at the lower of cost or net realizable value and recognized on a weighted-average cost method. The Company uses actual cost to
determine the cost basis for inventory. Inventory is capitalized based on when future economic benefit is expected to be realized. Due to the nature of the
Company’s supply chain process, inventory that is owned by the Company, is physically stored at third-party warehouses, logistics providers, and contract
manufacturers. The Company began capitalizing inventory upon receiving FDA approval for COSELA on February 12, 2021. Prior to FDA approval of
COSELA, expenses associated with the manufacturing of the Company's products were recorded as research and development expense.

Inventory valuation is established based on a number of factors including, but not limited to, finished goods not meeting product specifications, product
excess and obsolescence, or application of the lower of cost or net realizable value concepts. The determination of events requiring the establishment of
inventory valuation, together with the calculation of the amount of such adjustments may require judgment. The Company analyzes its inventory levels on
a periodic basis to determine if any inventory is at risk for expiration prior to sale or has a cost basis that is greater than its estimated future net realizable
value. Any adjustments are recognized through

F-9

 
 
 
cost of sales in the period in which they are incurred. No inventory valuation adjustments have been recorded for any periods presented.

Revenue Recognition

For elements of those arrangements that we determine should be accounted for under ASC 606, Revenue from Contracts with Customers (“ASC 606”), we
assess which activities in our license or collaboration agreements are performance obligations that should be accounted for separately and determine the
transaction  price  of  the  arrangement,  which  includes  the  assessment  of  the  probability  of  achievement  of  future  milestones  and  other  potential
consideration.  For  arrangements  that  include  multiple  performance  obligations,  such  as  granting  a  license  or  performing  manufacturing  or  research  and
development  activities,  we  allocate  the  transaction  price  based  on  the  relative  standalone  selling  price  and  recognize  revenue  that  is  allocated  to  the
respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. Accordingly, we develop
assumptions  that  require  judgment  to  determine  the  standalone  selling  price  for  each  performance  obligation  identified  in  the  contract.  These  key
assumptions may include revenue forecasts, clinical development timelines and costs, discount rates and probabilities of clinical and regulatory success.

Licenses of Intellectual Property

If a license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the
Company recognizes revenue allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the
license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to
determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring
progress for purposes of recognizing revenue associated with the bundled performance obligation. The Company evaluates the measure of progress each
reporting period and, if necessary, adjusts the measure of progress and related revenue recognition.

Milestone Payments

At the inception of each arrangement that includes developmental and regulatory milestone payments, the Company evaluates whether the achievement of
each milestone specifically relates to the Company’s efforts to satisfy a performance obligation or transfer a distinct good or service within a performance
obligation. The Company evaluates each milestone to determine when and how much of the milestone to include in the transaction price. The Company
first estimates the amount of the milestone payment that the Company could receive using either the expected value or the most likely amount approach.
The Company primarily uses the most likely amount approach as that approach is generally most predictive for milestone payments with a binary outcome.
Then, the Company considers whether any portion of that estimated amount is subject to the variable consideration constraint (that is, whether it is probable
that  a  significant  reversal  of  cumulative  revenue  would  not  occur  upon  resolution  of  the  uncertainty).  The  Company  updates  the  estimate  of  variable
consideration included in the transaction price at each reporting date which includes updating the assessment of the likely amount of consideration and the
application of the constraint to reflect current facts and circumstances.

Royalties

For  arrangements  that  include  sales-based  royalties,  including  milestone  payments  based  on  the  level  of  sales,  and  the  license  is  deemed  to  be  the
predominant  item  to  which  the  royalties  relate,  the  Company  will  recognize  revenue  at  the  later  of  (i)  when  the  related  sales  occur,  or  (ii)  when  the
performance  obligation  to  which  some  or  all  of  the  royalty  has  been  allocated  has  been  satisfied  (or  partially  satisfied).  To  date,  the  Company  has  not
recognized any revenue related to sales-based royalties or milestone payments based on the level of sales.

Product Sales, Net

The  Company  sells  COSELA  to  specialty  distributors  in  the  U.S.  and,  in  accordance  with  ASC  606,  recognizes  revenue  at  the  point  in  time  when  the
customer is deemed to have obtained control of the product. The customer is deemed to have obtained control of the product at the time of physical receipt
of the product at the customers’ distribution facilities, or Free on Board (“FOB”) destination, the terms of which are designated in the contract.

Product sales are recorded at the net selling price, which includes estimates of variable consideration for which reserves are established for (a) rebates and
chargebacks, (b) co-pay assistance programs, (c) distribution fees, (d) product returns, and (e) other discounts. Where appropriate, these estimates take into
consideration a range of possible outcomes which are probability-weighted for relevant factors such as current contractual and statutory requirements, and
forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is
entitled based on the terms of the applicable contract. The amount of variable consideration may be constrained and is included in the net sales price only to
the extent

F-10

 
that  it  is  probable  that  a  significant  reversal  in  the  amount  of  the  cumulative  revenue  recognized  will  not  occur  in  a  future  period. Actual  amounts  of
consideration ultimately received may differ from the Company's estimates. If actual results in the future vary from estimates, the Company adjusts these
estimates, which would affect net product revenue and earnings in the period such variances become known.

Liabilities related to co-pay assistance, rebates, and GPO fees are classified as “Accrued Expenses” in the Condensed Balance Sheets. Discounts such as
chargebacks, returns, and specialty distributor fees are recorded as a reduction to trade accounts receivable, which is included in “Accounts Receivable” in
the Condensed Balance Sheets.

Forms of Variable Consideration

Rebates  and  Chargebacks:  The  Company  estimates  reductions  to  product  sales  for  Public  Health  Service  Institutions,  such  as  Medicaid,  Medicare  and
Veterans  Administration  (“VA”)  programs,  as  well  as  certain  other  qualifying  federal  and  state  government  programs,  and  other  group  purchasing
organizations. The Company estimates these reductions based upon the Company’s contracts with government agencies and other organizations, statutorily
defined discounts and estimated payor mix. These organizations purchase directly from the Company’s specialty distributors at a discount and the specialty
distributors charge the Company back the difference between the wholesaler price and the discounted price. The Company’s liability for Medicaid rebates
consists of estimates for claims that a state will make. The Company’s reserve for this discounted pricing is based on expected sales to qualified healthcare
providers and the chargebacks that customers have already claimed.

Co-pay assistance: Eligible patients who have commercial insurance may receive assistance from the Company to reduce the patient’s out of pocket costs.
Liabilities for co-pay assistance are calculated by actual program participation from third-party administrators.

Distribution Fees: The Company has written contracts with its customers that include terms for distribution fees and costs for inventory management. The
Company estimates and records distribution fees due to its customers based on gross sales.

Product Returns: The Company generally offers a right of return based on the product’s expiration date and certain spoilage and damaged instances. The
Company  estimates  the  amount  of  product  sales  that  may  be  returned  and  records  the  estimate  as  a  reduction  of  product  sales  in  the  period  the  related
product sales are recognized. The Company’s estimates for expected returns are based primarily on an ongoing analysis of sales information and visibility
into the inventory remaining in the distribution channel.

Cash and Cash Equivalents

The  Company  considers  all  highly  liquid  investments  purchased  with  an  original  maturity  of  three  months  or  less  at  the  date  of  purchase  to  be  cash
equivalents.  Cash  and  cash  equivalents  at  December  31,  2021  and  2020  consist  of  amounts  on  deposit  in  banks,  including  checking  accounts,  money
market accounts and certificates of deposit. Cash deposits are all in financial institutions in the United States. As part of the lease for the new office space,
the  Company  obtained  a  standby  letter  of  credit  in  the  amount  of  $0.5  million  related  to  the  security  deposit.  This  letter  of  credit  is  secured  by  money
market funds at the financial institution. Therefore, these funds are classified as restricted cash on the balance sheet. The letter of credit will be reduced
ratably  on  each  anniversary  of  the  commencement  of  the  lease  until  the  end  of  the  lease  term.  As  of  December  31,  2021,  restricted  cash  totaled  $0.4
million.

Concentration of Credit Risk

Financial  instruments  that  potentially  subject  the  Company  to  credit  risk  consist  of  cash  and  cash  equivalents.  Deposits  with  financial  institutions  are
insured, up to certain limits, by the Federal Deposit Insurance Corporation (“FDIC”). The Company’s cash deposits often exceed the FDIC insurance limit;
however, all deposits are maintained with high credit quality institutions and the Company has not experienced any losses in such accounts. The financial
condition of financial institutions is periodically reassessed, and the Company believes the risk of any loss is minimal. The Company believes the risk of
any loss on cash due to credit risk is minimal.

Property and Equipment

Property  and  equipment  are  stated  at  cost  less  accumulated  depreciation.  Depreciation  is  generally  calculated  using  the  straight-line  method  over  the
following estimated useful lives:

Computer equipment
Laboratory equipment
Furniture and fixtures
Leasehold improvements

   5 years
   5 years
   7 years
   7 years

F-11

 
 
 
 
 
 
 
 
Costs  associated  with  maintenance  and  repairs  are  charged  to  expense  as  incurred.  Property  and  equipment  held  under  leasehold  improvements  are
amortized over the shorter of the lease term or the estimated useful life of the related asset.

Impairment of Long-lived Assets

The Company evaluates its long-lived assets for indicators of possible impairment by comparison of the carrying amounts to future net undiscounted cash
flows expected to be generated by such assets when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable.
Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s fair value based on
discounted estimates of future cash flows. For the years ended December 31, 2021, 2020 and 2019, the Company’s management evaluated its long-lived
assets and determined no impairment charge was needed.

Cost of Goods Sold

Cost of goods sold includes direct and indirect costs related to the manufacturing and distribution of COSELA, including third-party manufacturing costs,
packaging  services,  freight-in,  third-party  logistics  costs  associated  with  COSELA,  and  Company  personnel  costs.  Cost  of  goods  sold  may  also  include
period costs related to certain inventory manufacturing services and inventory adjustment charges. In connection with the FDA approval of COSELA on
February 12, 2021, the Company subsequently began capitalizing inventory manufactured or purchased after this date. As a result, certain manufacturing
costs associated with product shipments of COSELA were expensed prior to FDA approval and, therefore, are not included in cost of goods sold during the
current period.

Research and Development

Research and development expenses consist of costs incurred to further the Company’s research and development activities and include salaries and related
employee  benefits,  manufacturing  of  pharmaceutical  active  ingredients  and  drug  products,  costs  associated  with  clinical  trials,  nonclinical  activities,
regulatory activities, research-related overhead expenses and fees paid to expert consultants, external service providers and contract research organizations
which  conduct  certain  research  and  development  activities  on  behalf  of  the  Company.  Costs  incurred  in  the  research  and  development  of  products  are
charged to research and development expense as incurred.

Each  reporting  period,  management  estimated  and  accrued  research  and  development  expenses,  including  external  clinical  study  costs  associated  with
clinical trial activities. The process of estimating and accruing expenses involved reviewing contracts and purchase orders, identifying services that have
been provided on the Company’s behalf, and estimating the level of service performed and the associated cost incurred for the service when the Company
has not yet been invoiced or otherwise notified of the actual costs.

Costs for clinical trial activities were estimated based on an evaluation of vendors’ progress towards completion of specific tasks, using data such as patient
enrollment, clinical site activations or information provided by vendors regarding their actual costs incurred. Payments for these activities are based on the
terms of individual contracts and payment timing may differ significantly from the period in which the services were performed. The Company determines
accrual estimates through reports from and discussions with applicable personnel and outside service providers as to the progress or state of completion of
trials,  or  the  services  completed.  The  estimates  of  accrued  external  clinical  study  costs  as  of  each  balance  sheet  date  are  based  on  the  facts  and
circumstances known at the time.

Fair value of Financial Instruments

The Company provides disclosure of financial assets and financial liabilities that are carried at fair value based on the price that would be received upon
sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements may
be classified based on the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities using the following three levels:

Level 1

Level 2

Inputs  are  unadjusted  quoted  prices  in  active  markets  for  identical  assets  or  liabilities  that  the  Company  has  the  ability  to  access  at  the
measurement date.

Inputs  include  quoted  prices  for  similar  assets  and  liabilities  in  active  markets,  quoted  prices  for  identical  or  similar  assets  or  liabilities  in
markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally
from or corroborated by observable market data by correlation or other means.

Level 3

Unobservable inputs that reflect the Company’s estimates of the assumptions that market participants would use in pricing the asset or liability.
The Company develops these inputs based on the best information available, including its own data.

F-12

 
 
 
 
  
 
 
  
 
 
  
The carrying amounts of cash, cash equivalents, accounts payable and accrued liabilities approximate fair value because of their short-term nature.

At  December 31, 2021 and 2020 these financial instruments and respective fair values have been classified as follows (in thousands):

During the twelve months ended December 31, 2021 and December 31, 2020, there were no changes in valuation methodology.

The Loan Payable (discussed in Note 8), which is classified as a Level 3 liability, has a variable interest rate and the carrying value approximates its fair
value. As of December 31, 2021, the carrying value was $75.2 million.

Patent Costs

Costs associated with the submission of patent applications are expensed as incurred given the uncertainty of the future economic benefits of the patents.
Patent-related  legal  expenses  included  in  selling,  general  and  administrative  costs  were  approximately  $1,934  thousand,  $2,761  thousand,  and  $2,114
thousand for the years ended December 31, 2021, 2020 and 2019, respectively.  

Income Taxes

Income  taxes  are  accounted  for  using  the  asset  and  liability  method.  Deferred  tax  assets  and  liabilities  are  recognized  for  the  future  tax  consequences
attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating
loss  carryforwards,  and  tax  credit  carryforwards.  Deferred  tax  assets  and  liabilities  are  measured  using  enacted  tax  rates  expected  to  apply  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 income in the period that includes the enactment date.

In  accordance  with  Financial  Accounting  Standards  Board  (FASB)  Accounting  Standards  Codification  (ASC)  740,  Accounting  for  Income  Taxes,  the
Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only
when  it  is  considered  ‘more-likely-than-not’  that  the  position  taken  will  be  sustained  by  a  taxing  authority.  As  of  December  31,  2021  and  2020,  the
Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s effective income tax rate associated with
these  items.  The  Company’s  policy  for  recording  interest  and  penalties  relating  to  uncertain  income  tax  positions  is  to  record  them  as  a  component  of
income tax expense in the accompanying statements of operations. As of December 31, 2021 and 2020, the Company had no such accruals.

Stock-Based Compensation

The primary type of stock-based payments utilized by the Company are stock options. The Company accounts for stock-based employee compensation
arrangements by measuring the cost of employee services received in exchange for all equity awards granted

F-13

 
 
 
 
 
   
   
   
 
   
      
      
      
  
   
 
 
 
 
   
   
   
 
   
      
      
      
  
   
 
 
 
 
 
 
based on the fair value of the award on the grant date. The fair value of each employee stock option is estimated on the date of grant using an options
pricing model. The Company currently uses the Black-Scholes valuation model to estimate the fair value of its share-based payments. The model requires
management to make a number of assumptions including expected volatility, expected life, risk-free interest rate and expected dividends.

The Company also incurs stock-based compensation expense related to restricted stock units (“RSUs”) granted to employees. The fair value of RSUs is
determined by the closing market price of the Company’s common stock on the date of grant and then recognized over the requisite service period of the
award.

Segment Information

The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. All of the Company’s
assets are held in the United States.

Comprehensive Loss

Comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than
those with stockholders. There was no difference between net loss and comprehensive loss for each of the periods presented in the accompanying financial
statements.

Leases
We determine if an arrangement is a lease at inception. Operating lease assets represent our right to use an underlying asset for the lease term and lease
liabilities  represent  our  obligation  to  make  lease  payments  arising  from  the  lease.  Operating  leases  are  included  in  operating  lease  assets,  other  current
liabilities, and operating lease liabilities on our balance sheet at December 31, 2021. Operating lease assets and operating lease liabilities are recognized
based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an
implicit rate, we use our incremental borrowing rate based on the information available at commencement date to determine the present value of future
payments.  Our  lease  terms  may  include  options  to  extend  or  terminate  the  lease  when  it  is  reasonably  certain  that  we  will  exercise  that  option.  Lease
expense for minimum lease payments is recognized on a straight-line basis over the lease term.

Debt Issuance Costs

Debt issuance costs are amortized to interest expense over the estimated life of the related debt based on the effective interest method. In accordance with
ASC 835, Interest, we present debt issuance costs on the condensed balance sheet as a direct deduction from the associated debt.

Coronavirus (COVID-19) Impact on Operations

The Company has implemented business continuity plans to address the COVID-19 pandemic and minimize disruptions to ongoing operations. To date,
enrollment of patients in current clinical trials have not been impacted by COVID-19. Although the Company has not had any significant supply chain
delays or shortages as a result of the COVID-19 pandemic to date, the Company has experienced delays in the delivery of its investigational product to
certain investigative sites due to shortages of ancillary materials and the delay of governmental inspections. To date, the Company is on track to meet all of
its  previously  announced  clinical  milestones.  COVID-19  travel  limitations  and  government-mandated  work-from-home  or  shelter-in-place  orders,  has
reduced  the  number  of  in-person  meetings  in  2021  with  prescribers  and  fewer  patient  visits  with  physicians,  potentially  resulting  in  fewer  new
prescriptions.

The Company established a COVID-19 response team which continually monitors the impact of COVID-19 on its operations. The COVID-19 response
team manages workplace protocols that govern employees use of our office. To mitigate the impact of COVID-19 on its business, the Company put in place
the following safety measures for its employees, patients, healthcare professionals, and suppliers to limit exposure: the Company substantially restricted
travel, supplied personal protective equipment to employees, limited access to its headquarters and asked most of its staff to work remotely. In addition, the
Company transitioned most of its employees to working remotely and added bandwidth and VPN capacity to its infrastructure. The Company will continue
to monitor the impact of COVID-19 on its operations, including how it will impact our employees, clinical trials, development programs, supply chain, and
other aspects of our operations, and report to the Board regularly on the progress of its response to the COVID-19 outbreak.

5. Patent License Agreement

On November 23, 2016, the Company entered into a license agreement with the Board of Trustees of the University of Illinois (“the University”), which
was  amended  on  March  24,  2017.  Pursuant  to  the  license  agreement,  as  amended,  the  University  licensed  patent  rights  to  the  Company,  with  rights  of
sublicense, to make, have made, use, import, sell and offer for sale products covered by certain patent rights owned by the University. The rights licensed to
the Company are exclusive, worldwide, non-transferable rights, for all fields of use. Under the terms of the agreement the Company paid a one-time only,
non-refundable license issue fee in the amount of $0.5 million which was charged to research and development expense in the fourth quarter of 2016.

The Company is also obligated to pay annual maintenance fees to the University. All annual minimum payments are fully creditable against any royalty
payments made by the Company. Under the terms of the agreement, the Company must pay the University royalty percentage on all net sales of products
and a share of sublicensing revenues. In addition, the University is eligible to receive milestone payments of up to $2.6 million related to the initiation and
execution of clinical trials and the first commercial sale of a product in another country. To date, the Company has made milestone payments totaling $0.6
million, of which $0 was incurred during 2021. The Company will be responsible for any future patent prosecution costs that may arise.

cure such failure within thirty (30) days after receipt of notice from the University, (ii) is in breach of any provision of the agreement and fails to remedy
within  forty-five  (45)  days  after  receipt  of  notice,  (iii)  makes  a  report  to  the  University  under  the  agreement  that  is  determined  to  be  materially  false,

written  notice  to  the  University  at  least  ninety  (90)  days  prior  to  the  termination  date  specified  in  the  notice.  Upon  expiration  or  termination  of  the
agreement, all rights revert to the University.

7. Leases

We  adopted  ASC  842  as  of  January  1,  2019.  Prior  period  amounts  have  not  been  adjusted  and  continue  to  be  reported  in  accordance  with  our  historic
accounting under ASC 840.

Pursuant to a lease agreement dated January 10, 2014 (the “Lease”), on April 1, 2014, the Company leased office and lab space with a free rent period and
escalating rent payments; the Lease had an expiration date of July 31, 2017. The Lease was amended on January 27, 2016 to lease new larger office and lab
space beginning in August 2016 with a discounted rent period and escalating rent payments and the Lease term was extended to December 31, 2022. The
amendment also contained an option for a five-year renewal and a right of first refusal to lease adjacent office space. The Lease was further amended on
March  27,  2017  to  lease  additional  office  space  beginning  in  August  2017  with  a  discounted  rent  period  and  escalating  rent  payments.  The  Lease  was
amended  again  in  January  2018  to  lease  additional  adjacent  office  space  beginning  in  August  2018  with  a  discounted  rent  period  and  escalating  rent
payments.  The  term  of  the  renewal  option  contained  in  the  Lease,  as  amended,  was  not  included  in  the  measurement  of  the  operating  lease  asset  and
liability since exercise of the option was uncertain.

On March 20, 2020, the Lease was amended to surrender three of the office spaces previously entered into above, with a termination date of May 31, 2020
and in consideration of a termination fee to be paid. The lease payments and term for the remaining occupied space will remain the same. Due to these
changes in lease terms for the three office spaces, in March 2020 the Company modified the operating lease liabilities and operating lease assets of these
three office spaces to reflect the new terms.

In November 2018, the Company signed a new lease to secure approximately 60,000 square feet of laboratory and office space at 700 Park Offices Drive in
Research Triangle Park, NC (“700 Lease”). The 700 Lease commenced on September 2, 2019 and has an expiration date of September 30, 2027 for the
initial term with the Company having the option to renew for an additional 5 years. The term of the renewal option contained in the Lease was not included
in the measurement of the operating lease asset and liability since exercise of the option was uncertain. As part of the 700 Lease, the Company obtained a
standby letter of credit in the amount of $0.5 million related to the security deposit. This letter of credit is secured by money market funds at the financial
institution. Therefore, these funds are classified as restricted cash on the balance sheet. The letter of credit will be reduced ratably on each anniversary of
the commencement of the 700 Lease until the end of the lease term.

8. Loan Payable

On May 29, 2020, the Company entered into a loan and security agreement (the “Loan Agreement”) with Hercules Capital, Inc. (“Hercules”), under which
Hercules has agreed to lend the Company up to $100.0 million, to be made available in a series of tranches, subject to certain terms and conditions. The
first tranche totals $30.0 million, of which the Company received $20.0 million at closing. Upon initiation of the phase 3 trial of COSELA for metastatic
colorectal cancer and receiving FDA approval for COSELA for small cell lung cancer (“the Performance Milestone”), the second tranche of $20.0 million
became available to the Company for drawdown through December 15, 2021. The third tranche of $30.0 million will be available through December 31,
2022. The fourth tranche of $20.0 million will be available at Hercules’ approval through December 31, 2022. On March 31, 2021, the Company entered
into  the  First  Amendment  to  Loan  and  Security  Agreement  (the  “First  Amendment”)  with  Hercules  whereby  the  Company  drew  the  remaining  $10.0
million  of  the  first  tranche  and  the  interest  rate  and  financial  covenants  were  amended.  Unless  loan  advances  exceeded  $40.0  million,  no  financial
covenants were required.

Amounts borrowed under the Loan Agreement will bear an interest rate equal to the greater of either (i) (a) the prime rate as reported in The Wall Street
Journal, plus (b) 6.40%, and (ii) 9.65%. Based on original terms of the Loan Agreement, the Company will make interest only payments through June 1,
2022  and  following  the  interest  only  period,  the  Company  will  repay  the  principal  balance  and  interest  of  the  advances  in  equal  monthly  installments
through  June  1,  2024.  Based  on  the  original  terms  of  the  Loan  Agreement,  upon  satisfaction  of  the  Performance  Mileston,  the  interest  only  period  was
extended through January 1, 2023 and the maturity date was extended to June 1, 2025. Upon entering into the First Amendment on March 31, 2021, the
interest rate was amended to the greater of either (i) (a) the prime rate as reported in The Wall Street Journal, plus (b) 6.20%, and (ii) 9.45%.

The Company may prepay advances under the Loan Agreement, in whole or in part, at any time subject to a prepayment charge equal to (a) 3.0% of the
prepayment amount in the first year; (b) 2.0% of the prepayment amount in the second year; and (c) 1.0% of the prepayment amount in the third year.

Upon prepayment or repayment of all or any of the advances under the Loan Agreement, the Company will pay (in addition to the prepayment charge) an
end of term charge of 6.95% of the aggregate funded amount. With respect to the first tranche, the end of term charge of $2.1 million will be payable upon
any prepayment or repayment. To the extent that the Company is provided additional advances under the Loan Agreement, the 6.95% end of term charge
will be applied to such additional amounts. These amounts have been accrued over the term of the loan using effective-interest method.

On  November  1,  2021,  the  Company  entered  into  a  Second  Amendment  to  Loan  and  Security  Agreement  (the  “Second  Amendment”)  under  which
Hercules agreed to lend the Company up to $150.0 million, to be made available in a series of tranches, subject to certain terms and conditions. The first
tranche  was  increased  to  $100.0  million.  At  close  of  the  Second  Amendment,  the  Company  borrowed  an  additional  $45.0  million  from  Tranche  1  with
$25.0 million remaining to be borrowed through September 15, 2022. The second tranche of $20.0 million will become available to the Company upon
achievement of $50.0 million trailing six-month net product revenue of COSELA no later than June 30, 2023 and will be available through December 15,
2023. The third tranche of $15.0 million will become available upon achievement of certain development performance milestones and available through
December 15, 2023. The fourth tranche of $15.0 million will be available at Hercules’ approval through June 30, 2024.

Amounts borrowed under the Second Amendment will bear an interest rate equal to the greater of either (i) (a) the prime rate as reported in The Wall Street
Journal,  plus  (b)  5.90%,  and  (ii)  9.15%.  The  Company  will  make  interest  only  payments  through  December  1,  2024  and  may  be  extended  through
December  1,  2025,  in  quarterly  increments,  subject  to  compliance  with  covenants  of  the  Second  Amendment.  Following  the  interest  only  period,  the
Company will repay the principal balance and interest of the advances in equal monthly installments through November 1, 2026.

The Company may prepay advances under the Second Amendment, in whole or in part, at any time subject to a prepayment charge equal to (a) 3.0% of the
prepayment amount in the first year from the closing of the Second Amendment; (b) 2.0% of the prepayment amount in the second year from the closing of
the Second Amendment; and (c) 1.0% of the prepayment amount in the third year from the closing of the Second Amendment.

Upon prepayment or repayment of all or any of the advances under the Second Amendment, the Company will pay (in addition to the prepayment charge)
an end of term charge of 6.75% of the aggregate amount funded. The Company will be required to make a final payment to Hercules in the amount of
6.75% of the amounts funded, less any amount previously paid. In addition, the Company will be required to make a payment to the lender for $2.1 million
on the earliest occurrence of (i) June 1, 2025, (ii) the date the Company repays the outstanding principal amount in full, or (iii) the date that the principal
amount becomes due and payable in full.

The  Second  Amendment  is  secured  by  substantially  all  of  the  Company’s  assets,  including  intellectual  property,  subject  to  certain  exemptions.  The
Company out-licensed lerociclib as permitted in the Loan Agreement and the Company may out-license rintodestrant upon approval of the licensing terms
by Hercules.

The Second Amendment contains a minimum revenue covenant. Beginning August 15, 2022, with the reporting of the financial results for the second fiscal
quarter  ended  June  30,  2022,  and  tested  monthly,  the  Company  must  have  achieved  net  product  revenue  of  COSELA  of  at  least  65%  of  the  amounts
projected in the Company’s forecast. Testing of the minimum revenue covenant shall be

F-18

 
 
waived at any time in which either (a) the Company’s market capitalization exceeds $750.0 million and the Company maintains unrestricted cash equal to
at least 50% of the total amounts funded, or (b) the Company maintains unrestricted cash equal to at least 100% of the total amounts funded.

The Company evaluated the Second Amendment under the guidance found in ASC 470-50 Modification and Extinguishment.  The  Company  concluded
that the previous debt under the Loan Agreement was extinguished based on the difference in present value of the cash flows of the Loan Agreement and
the  Second  Amendment.  Accordingly,  the  difference  between  the  carrying  value  of  the  Loan  Agreement  as  of  November  1,  2021,  including  the
unamortized debt issuance costs, and the fair value of the Second Amendment was recorded as a $0.2 million loss on extinguishment of debt for the twelve
months ended December 31, 2021. Fees paid to third parties directly related to the funded portion of the Second Amendment have been capitalized as debt
issuance costs and will be amortized to interest expense over the life of the Second Amendment using the effective interest method. Fees paid that were
directly  related  to  the  unfunded  portion  is  account  for  as  a  deferred  financing  charge  and  amortized  to  interest  expense  over  the  period  the  unfunded
portions  are  available.  The  end  of  term  charges  associated  with  the  Second  Amendment  are  being  accreted  through  interest  expense  using  the  effective
interest method over the related term of the debt. During the twelve months ended December 31, 2021, the Company recognized $4.7 million of interest
expense related to the debt, inclusive of the loss on extinguishment, which is reflected in other income (expense), net on the statement of operations.

As of December 31, 2021 the future principal payments due under the Loan Agreement, excluding interest, are as follows:

9. Stockholders’ Equity

Common stock

The Company’s common stock has a par value of $0.0001 per share and consists of 120,000,000 authorized shares as of December 31, 2021 and 2020,
respectively.  Holders of common stock are entitled to one vote per share and are entitled to receive dividends, as if and when declared by the Company’s
Board of Directors.

On June 15, 2018, the Company entered into a sales agreement for “at the market offerings” with Cowen and Company, LLC (“Cowen”), which allowed
the Company to issue and sell shares of common stock pursuant to a shelf registration statement for total gross sales proceeds of up to $125.0 million from
time to time through Cowen, acting as its agent. Between January 14, 2021 and February 9, 2021, the Company sold 3,513,027 shares of common stock
pursuant  to  this  agreement  resulting  in  $86.4  million  in  net  proceeds.  As  of  February  9,  2021,  the  Company  has  used  the  entirety  of  the  remaining
availability under the 2018 sales agreement with Cowen.

On July 2, 2021, the Company filed an automatic shelf registration statement on Form S-3 with the Securities and Exchange Commission (the “SEC”),
which became effective upon filing, pursuant to which the Company registered for sale an unlimited amount of any combination of its common stock,
preferred stock, debt securities, warrants, rights and/or units from time to time and at prices and on terms that the Company may determine, so long as the
Company continued to satisfy the requirements of a “well-known seasoned issuer” under SEC rules (the “2021 Form S-3”).

In  connection  with  the  2021  Form  S-3,  on  July  2,  2021,  the  Company  entered  into  a  sales  agreement  for  “at  the  market  offerings”  with  Cowen,  which
allowed the Company to issue and sell shares of common stock pursuant to the 2021 Form S-3 for total gross sales proceeds of up to $150.0 million from
time to time through Cowen, acting as its agent (the “2021 Sales Agreement”). The Company did not sell any shares of common stock under the 2021 Sales
Agreement.

On February 23, 2022, because the Company is no longer a “well-known seasoned issuer” as such term is defined in Rule 405 under the Securities Act of
1933, as amended, the Company filed an automatic post-effective amendment to the 2021 Form S-3 on Form POSASR, which became effective upon
filing, to register for sale up to $300.0 million of any combination of its common stock, preferred stock, debt securities, warrants, rights and/or units from
time to time and at prices and on terms that the Company may determine and, as required by SEC rules, will file another post-effective amendment to the
2021 Form S-3 on Form POS AM after the filing of this Form 10-K. Once the post-effective amendment to the 2021 Form S-3 on Form POS AM has been
declared effective by the SEC, the 2021 Form S-3 will remain in effect for up to three years from the date it originally became effective, which was July 2,
2021. The Company makes no assurances as to the continued effectiveness of the 2021 Form S-3 after the declaration of effectiveness of the post-effective
amendment to the 2021 Form S-3 on Form POS AM. The 2021 Form S-3 also includes a prospectus covering up to an aggregate of $100.0 million in
common stock that the Company may issue and sell from time to time, through Cowen acting as its sales agent, pursuant to that certain sales agreement that
the Company entered into with Cowen on February 23, 2022 (the “2022 Sales Agreement”). In connection with the Company entering into the 2022 Sales
Agreement with Cowen, the Company terminated the 2021 Sales Agreement.

Preferred stock

Upon completion of the IPO, all outstanding preferred stock was automatically converted into 18,933,053 shares of common stock.  The Company is also
authorized  to  issue  5,000,000  shares  of  undesignated  preferred  stock  in  one  or  more  series.   As  December  31,  2021,  no  shares  of  preferred  stock  were
issued or outstanding.

Shares Reserved for Future Issuance

The Company has reserved authorized shares of common stock for future issuance at December 31, 2021 and December 31, 2020 as follows:

10. Stock-Based Compensation

2011 Equity Incentive Plan

In March 2011, the Company adopted the 2011 Equity Incentive Plan (the “Plan”).  As amended, 4,400,640 shares of common stock were reserved for
issuance under the 2011 Plan.  Eligible plan participants included employees, directors, officers, consultants and advisors of the Company. The 2011 plan
permitted the granting of incentive stock options, nonqualified stock options and other stock- based awards. In connection with the adoption of the 2017
Plan (as defined below), the 2011 Plan was terminated and no further awards will be made under the 2011 Plan.

2017 Equity Incentive Plan

In  May  2017,  the  Company  adopted  the  2017  Equity  Incentive  Plan  (the  “2017  Plan”).  The  2017  Plan  provided  for  the  direct  award  or  sale  of  the
Company’s  common  stock  and  for  the  grant  of  up  to  1,932,000  stock  options  to  employees,  directors,  officers,  consultants  and  advisors  of  the
Company.  The 2017 Plan provides for the grant of incentive stock options, non-statutory stock options or restricted stock. Effective January 1, 2021, and in
accordance with the “evergreen” provision of the 2017 plan, an additional 1,096,553 shares were made available for issuance.

Under both the 2011 Plan and the 2017 Plan, options to purchase the Company’s common stock may be granted at a price no less than the fair market value
of a share of common stock on the date of grant.  The fair value shall be the closing sales price for a share as quoted on any established securities exchange
for such grant date or the last preceding date for which such quotation exists.  Vesting terms of options issued are determined by the Board of Directors or
Compensation Committee of the Board.  The Company’s stock options vest based on terms in the stock option agreements.  Stock options have a maximum
term of ten years.

Beginning in January 2021, the Company began granting Restricted Stock Units (“RSUs”) under the 2017 Plan. RSUs are granted at the fair market value
of a share of common stock on the date of grant.

As of December 31, 2021, there were a total of 1,307,735 shares of common stock available for future issuance under the 2017 Plan.

2021 Inducement Equity Incentive Plan

In February 2021, the Company adopted the 2021 Inducement Equity Incentive Plan (the “2021 Inducement Plan”). The 2021 Inducement Plan provides
for the grant of up to 500,000 non-qualified options, stock grants, and stock-based awards to employees and directors of the Company. The 2021
Inducement Plan does not include an evergreen provision.

As of December 31, 2021, there were a total of 68,900 shares of common stock available for future issuance under the 2021 Inducement Plan.

2021 Sales Force Inducement Equity Incentive Plan

In September 2021, the Company adopted the 2021 Sales Force Inducement Equity Incentive Plan (the “2021 Sales Force Inducement Plan”). The 2021
Sales Force Inducement Plan provides for the grant of up to 500,000 non-qualified options, stock grants, and stock-based awards to sales force individuals
and support staff that were not previously employees or directors of the Company. The 2021 Sales Force Inducement Plan does not include an evergreen
provision.

As of December 31, 2021, there were a total of 395,000 shares of common stock available for future issuance under the 2021 Sales Force Inducement Plan.

Stock-based Compensation

The Company recognizes compensation costs related to stock options granted to employees based on the estimated fair value of the awards on the date of
grant, net of estimated forfeitures. The grant date fair value of the stock-based awards is generally recognized on a straight-line basis over the requisite
service period, which is generally the vesting period of the respective awards.  Share-based awards granted to non-employee directors as compensation for
serving on the Company’s Board of Directors are accounted for in the same manner as employee share-based compensation awards.  

The Company calculates the fair value of stock options using the Black-Scholes option pricing model.  The Black-Scholes option-pricing model requires
the use of subjective assumptions, including the expected volatility of the Company’s common stock, the assumed dividend yield, the expected term of the
Company’s stock options and the fair value of the underlying common stock on the date of grant.

The Company also incurs stock-based compensation expense related to RSUs. The fair value of RSUs is determined by the closing market price of the
Company’s common stock on the date of grant and then recognized over the requisite service period of the award.

During the years ended December 31, 2021, 2020 and 2019, the Company recorded employee share-based compensation expense of $22,319, $18,770, and
$16,351, respectively. The Company recorded non-employee share-based compensation expense of $0, $0, and $98 during the years ended December 31,
2021, 2020 and 2019, respectively.  Total share-based compensation expense included in the statements of operations is as follows:

The  fair  value  of  each  option  grant  is  estimated  on  the  grant  date  using  the  Black-Scholes  option-pricing  model,  using  the  following  weighted  average
assumptions:

Expected volatility
Weighted-average risk free rate
Dividend yield
Expected term (in years)
Weighted-average grant-date fair value per share

The expected term of stock options represents the weighted-average period the stock options are expected to remain outstanding and is based on the option
vesting term, contractual terms and industry peers as the Company did not have sufficient historical information to develop reasonable expectations about
future exercise patterns and post-vesting employment termination behavior.

The expected stock price volatility assumptions for the Company’s stock options were determined by examining the historical volatilities for industry peers
as the Company does not have sufficient history to estimate volatility using only its common stock. In 2019, the Company began incorporating its historical
stock  price  in  conjunction  with  selected  similar  publicly  traded  companies.  The  Company  plans  to  continue  to  use  the  guideline  peer  group  volatility
information until the historical volatility of its common stock is sufficient to measure expected volatility for future option grants.

The risk-free interest rate assumption at the date of grant is based on the U.S. Treasury instruments whose term was consistent with the expected term of
the Company’s stock options.

The expected dividend assumption is based on the Company’s history and expectation of dividend payouts.

As of December 31, 2021, unrecognized compensation expense related to unvested stock options totaled $33.5 million, which is expected to be recognized
over a weighted-average period of approximately 2.4 years.

Prior to our initial public offering, the fair value of our common shares underlying our stock options was estimated on each grant date by our board of
directors.  In  order  to  determine  the  fair  value  of  our  common  shares  underlying  granted  stock  options,  our  board  of  directors  considered,  among  other
things,  timely  valuations  of  our  common  shares  prepared  by  an  unrelated  third-party  valuation  firm  in  accordance  with  the  guidance  provided  by  the
American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation.

Since the IPO, the board of directors has determined the fair value of each common share underlying share-based awards based on the closing price of the
common shares as reported by Nasdaq on the date of grant.

Restricted Stock Units

The  Company’s  restricted  stock  units  (“RSUs”)  are  considered  nonvested  share  awards  and  require  no  payment  from  the  employee.  For  each  RSU,
employees receive one common share at the end of the vesting period. Compensation cost is recorded based on the market price of the Company’s common
stock on the grant date and is recognized on a straight-line basis over the requisite service period.

The following table is a summary of the RSU activity for the twelve months ended December 31, 2021:

11. License Revenue

ARC License Agreement

On May 22, 2020, the Company entered into an exclusive license agreement with ARC Therapeutics, LLC (“ARC”), a company primarily owned by a
related party, whereby the Company granted to ARC an exclusive, worldwide, royalty-bearing license, with the right to sublicense, solely to make, have
made, use, sell, offer for sale, import, export, and commercialize products related to its cyclin dependent kinase 2 (“CDK2”) inhibitor compounds. At close,
the  Company  received  consideration  in  the  form  of  an  upfront  payment  of  $1.0  million  and  an  equity  interest  in  ARC  equal  to  10%  of  its  issued  and
outstanding units valued at $1.1 million. In addition, the Company may receive a future development milestone payment totaling $2.0 million and royalty
payments in the mid-single digits based on net sales of the licensed compound after commercialization. The Company has right of first negotiation to re-
acquire these assets.

The Company assessed the license agreement in accordance with ASC 606 and identified one performance obligation in the contract, which is the transfer
of the license, as ARC can benefit from the license using its own resources. The Company recognized $2.1 million in license revenue consisting of the
upfront payment and the 10% equity interest in ARC upon the effective date as the Company determined the license was a right to use the intellectual
property and the Company had provided all necessary information to ARC to benefit from the license.

The Company considers the future potential development milestones and sales-based royalties to be variable consideration. The development milestone is
excluded  from  the  transaction  price  because  it  determined  the  payment  to  be  fully  constrained  under  ASC  606  due  to  the  inherent  uncertainty  in  the
achievement of such milestone due to factors outside of the Company’s control. As sales-based royalties are all related to the license of the intellectual
property, the Company will recognize revenue in the period when subsequent sales are made pursuant to the sales-based royalty exception. The Company
will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

There was no revenue recognized during the twelve months ended December 31, 2021.

Genor License Agreement

On  June  15,  2020,  the  Company  entered  into  an  exclusive  license  agreement  with  Genor  Biopharma  Co.  Inc.  (“Genor”)  for  the  development  and
commercialization of lerociclib in the Asia-Pacific region, excluding Japan (the “Genor Territory”). Under the license agreement, the Company granted to
Genor an exclusive, royalty-bearing, non-transferable license, with the right to grant sublicenses, to develop, obtain, hold and maintain regulatory approvals
for, and commercialize lerociclib, in the Genor Territory.

Under  the  license  agreement,  Genor  agreed  to  pay  the  Company  a  non-refundable,  upfront  cash  payment  of  $6.0  million  with  the  potential  to  pay  an
additional $40.0 million upon reaching certain development and commercial milestones. In addition, Genor will pay the Company tiered royalties ranging
from high single to low double-digits based on annual net sales of lerociclib in the Genor Territory. In September 2020, the Company transferred to Genor
the related technology and know-how that is necessary to develop, seek regulatory approval for, and commercialize lerociclib in the Genor Territory, which
resulted in the recognition of $6.0 million in revenue in accordance with ASC 606.

During the twelve months ended December 31, 2021, the Company recognized $3.0 million of revenue related to development milestones which occurred
during the year.

EQRx License Agreement

On July 22, 2020, the Company entered into an exclusive license agreement with EQRx, Inc. (“EQRx”) for the development and commercialization of
lerociclib  in  the  U.S.,  Europe,  Japan  and  all  other  global  markets,  excluding  the  Asia-Pacific  region  (except  Japan)  (the  “EQRx  Territory”).  Under  the
license agreement, the Company granted to EQRx an exclusive, royalty-bearing, non-transferable license, with the right to grant sublicenses, to develop,
obtain, hold and maintain regulatory approvals for, and commercialize lerociclib in the EQRx Territory.

Under  the  license  agreement,  EQRx  agreed  to  pay  the  Company  a  non-refundable,  upfront  cash  payment  of  $20.0  million  with  the  potential  to  pay  an
additional $290.0 million upon reaching certain development and commercial milestones. In addition, EQRx will pay the Company tiered royalties ranging
from mid-single digits to mid-teens based on annual net sales of lerociclib in the EQRx Territory. In September 2020, the Company transferred to EQRx the
related technology and know-how that is necessary to develop, seek regulatory approval for, and commercialize lerociclib in the EQRx Territory which
resulted in the recognition of $20.0 million in revenue in accordance with ASC 606. EQRx will be responsible for the development of the product in the
EQRx Territory. The Company will continue until completion, as the clinical trial sponsor, its two primary clinical trials at EQRx’s sole cost and expense.
EQRx  will  reimburse  the  Company  for  all  of  its  out-of-pocket  costs  incurred  after  the  effective  date  of  the  license  agreement  in  connection  with  these
clinical trials. The Company will invoice EQRx within 30 days following the end of the quarter, and EQRx will pay within 30 days after its receipt of such
invoice.

F-24

 
 
 
For the twelve months ended December 31, 2021the Company recognized revenue of $4.8 million related to the delivery of clinical drug supply and
manufacturing services and $2.5 million for the reimbursement of costs associated with the two primary clinical trials for lerociclib. The amounts for
clinical drug supply and manufacturing services have been invoiced and paid. The amounts for clinical trial reimbursements that occurred during the
quarter are recognized as accounts receivable on the balance sheet as of December 31, 2021. No development and commercial milestones, as defined by the
agreement, have been achieved through December 31, 2021.

Simcere License Agreement

On August 3, 2020, the Company entered into an exclusive license agreement with Nanjing Simcere Dongyuan Pharmaceutical Co., Ltd (“Simcere”) for
the development and commercialization of trilaciclib in all indications in Greater China (mainland China, Hong Kong, Macau, and Taiwan) (the “Simcere
Territory”). Under the license agreement, the Company granted to Simcere an exclusive, royalty-bearing, non-transferable license, with the right to grant
sublicenses, to develop, obtain, hold and maintain regulatory approvals for, and commercialize trilaciclib in the Simcere Territory.

Under the license agreement, Simcere agreed to pay the Company a non-refundable, upfront cash payment of $14.0 million with the potential to pay an
additional $156.0 million upon reaching certain development and commercial milestones. In addition, Simcere will pay the Company tiered low double-
digit royalties on annual net sales of trilaciclib in the Simcere Territory. In accordance with ASC 606, the Company recognized the non-fundable, upfront
cash payment of $14.0 million (less applicable withholding taxes of $1.4 million) 2020 as the Company had transferred the license and related technology
and know-how to Simcere.

During the twelve months ended December 31, 2021 the Company recognized $8.0 million (less applicable withholding taxes of $0.8 million) related to
development milestones which were met during the period and $1.0 million for the reimbursement of clinical trial costs.

12. Net Loss per Common Share

Basic  net  loss  per  common  share  is  computed  using  the  weighted  average  number  of  common  shares  outstanding  during  the  period  including  nominal
issuances of common stock warrants. Diluted net loss per common share is computed using the sum of the weighted average number of common shares
outstanding during the period and, if dilutive, the weighted average number of potential shares of common stock, including the assumed exercise of stock
options, stock warrants and unvested restricted common stock. For the years ended December 31, 2021, 2020 and 2019, the following potentially dilutive
securities have been excluded from the computations of diluted weighted-average shares outstanding because the effect would be anti-dilutive:

Stock options issued and outstanding
Unvested RSU
Total potential diluted shares

Amounts in the table above reflect the common stock equivalents of the noted instruments.

13. Income Taxes

Income  taxes  are  accounted  for  using  the  asset  and  liability  method.  Deferred  tax  assets  and  liabilities  are  recognized  for  the  future  tax  consequences
attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating
loss  carryforwards,  and  tax  credit  carryforwards.  Deferred  tax  assets  and  liabilities  are  measured  using  enacted  tax  rates  expected  to  apply  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 income in the period that includes the enactment date.

In  accordance  with  FASB  ASC  740,  Accounting for Income Taxes,  the  Company  reflects  in  the  financial  statements  the  benefit  of  positions  taken  in  a
previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be
sustained by a taxing authority. As of December 31, 2021 and 2020, the Company had no unrecognized income tax benefits and correspondingly there is no
impact  on  the  Company’s  effective  income  tax  rate  associated  with  these  items.  The  Company’s  policy  for  recording  interest  and  penalties  relating  to
uncertain income tax positions is to record them as a component of income tax expense in the accompanying statements of operations. As of December 31,
2021 and 2020, the Company had no such accruals.

On November 18, 2021, North Carolina enacted the 2021 Appropriations Act, which included a gradual corporate income tax rate decrease from the
current 2.5% to 0% by 2030.  The Company is in a cumulative loss position and does not have significant deferred tax liabilities that can be utilized as a
source of taxable income in the future.  Therefore, the Company has reduced its North Carolina deferred tax assets, including the NOLs, to zero, as no
benefit is expected to be realized from these deferred tax assets prior to 2030 when there would be no income tax in North Carolina.  The reduction in the
value of the deferred tax assets resulted in $8.4 million of tax expense, which was offset fully by the reduction in the corresponding valuation allowance.  If
the Company becomes profitable prior to 2030, the Company will recognize an income tax benefit related to the portion of its North Carolina deferred tax
assets utilized.

The tax effects of temporary differences and operating loss carryforwards that gave rise to significant portions of the deferred tax assets and deferred tax
liabilities were as follows at December 31, 2021 and 2020 (in thousands):

At December 31, 2021 and December 31, 2020, the Company evaluated all significant available positive and negative evidence, including the existence of
losses in recent years and management’s forecast of future taxable income, and, as a result, determined it was more likely than not that federal and state
deferred tax assets, including benefits related to net operating loss carryforwards, would not be realized. The valuation allowance increased $27.6 million
from $109.8 million at December 31, 2020 to $137.4 million at December 31, 2021. The increase in valuation allowance was due primarily to the increase
in net operating loss carryforwards and income tax credits.

At December 31, 2021, the Company has federal net operating loss carryforwards (“NOLs”) of approximately $510.0 million, which are available to offset
future  taxable  income.  Of  the  $510.0  million  available,  $95.4  million  will  begin  to  expire  in  2029.  The  remaining  $414.6  million  has  an  indefinite
carryforward period. Under the Tax Cuts and Jobs Act (“Tax Act”), federal NOLs arising after December 31, 2017 may be carried forward indefinitely.
However, for NOLs arising after December 31, 2017, NOL carryforwards will be limited to 80% of taxable income. The Company’s NOLs generated in
2017 and in prior years will not be subject to the 80% limitation under the Tax Act. In addition, the Company has state net operating loss carryforwards
totaling approximately $332.7 million, which are available to offset future state taxable income. The state net operating loss carryforwards are inclusive of
North Carolina net operating losses, which are recorded at zero benefit, as discussed in this footnote. State net operating losses begin to expire in 2024.
Because  the  Company  has  incurred  cumulative  net  operating  losses  since  inception,  all  tax  years  remain  open  to  examination  by  U.S.  federal  and  state
income tax authorities. As of December 31, 2021, the Company also had federal

research and development (R&D) credit carryforwards of approximately $17.0 million available to offset future income tax which begin to expire in 2035.

In  accordance  with  FASB  ASC  740,  Accounting for Income Taxes,  the  Company  reflects  in  the  financial  statements  the  benefit  of  positions  taken  in  a
previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be
sustained by a taxing authority. As of December 31, 2021 and 2020, the Company had no unrecognized income tax benefits and correspondingly there is no
impact  on  the  Company’s  effective  income  tax  rate  associated  with  these  items.  The  Company’s  policy  for  recording  interest  and  penalties  relating  to
uncertain income tax positions is to record them as a component of income tax expense in the accompanying statements of income. As of December 31,
2021 and 2020, the Company had no such accruals.

Section 382 Limitation

The Company’s ability to utilize its net operating loss and research and development credit carryforwards may be substantially limited due to ownership
changes that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the Code),
as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to
offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or
series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the outstanding stock of a company by certain
stockholders or public groups.

In April 2019, the Company completed an evaluation study as to whether an “ownership change” had occurred and determined that the limitation would be
approximately $8.0 million on federal net operating loss carryforwards, $1.2 million on state net operating loss carryforwards, and $0.1 million on R&D
tax credit carryforwards. The carryforward amounts reported above have already been reduced for these limitations. The Company continues to maintain a
valuation allowance on the remaining NOLs as it believes that it is more likely than not that all of the deferred tax asset associated with the NOLs will not
be realized regardless of whether an “ownership change” has occurred.

14. Related Party Transactions

The  Company  maintained  a  consulting  agreement  with  a  Seth  A.  Rudnick,  M.D.,  a  member  of  the  Board  of  Directors,  for  scientific  advisory  services

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.2

General

The following description of our capital stock and provisions of our amended and restated certificate of incorporation and amended and restated by-laws
are summaries of material terms and provisions and are qualified by reference to our amended and restated certificate of incorporation and amended and
restated by-laws, copies of which have been filed with the SEC as exhibits to the registration statement of which this prospectus is a part.

Our authorized capital stock consists of 120,000,000 shares of common stock, par value $0.0001 per share, and 5,000,000 shares of preferred stock, par
value $0.0001 per share, all of which are undesignated. Only share of our common stock are and no shares of preferred stock outstanding.

Common stock

We are authorized to issue one class of common stock. Holders of our common stock are entitled to one vote for each share of common stock held of record
for the election of directors and on all matters submitted to a vote of stockholders. Holders of our common stock are entitled to receive dividends ratably, if
any, as may be declared by our board of directors out of legally available funds, subject to any preferential dividend rights of any preferred stock then
outstanding. Upon our dissolution, liquidation or winding up, holders of our common stock are entitled to share ratably in our net assets legally available
after the payment of all our debts and other liabilities, subject to the preferential rights of any preferred stock then outstanding. Holders of our common
stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of common stock are subject to,
and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future. Except as
described under the “—Anti-Takeover Effects of Delaware Law, Our Amended and Restated Certificate of Incorporation and Our Amended and Restated
By-Laws” section below, a majority vote of the holders of common stock is generally required to take action under our amended and restated certificate of
incorporation and amended and restated by-laws.

Preferred stock

Our board of directors is authorized, without action by the stockholders, to designate and issue up to an aggregate of 5,000,000 shares of preferred stock in
one or more series. Our board of directors can designate the rights, preferences and privileges of the shares of each series and any of its qualifications,
limitations or restrictions. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect
the voting power or other rights of the holders of common stock. The issuance of preferred stock, while providing flexibility in connection with possible
future financings and acquisitions and other corporate purposes could, under certain circumstances, have the effect of restricting dividends on our common
stock, diluting the voting power of our common stock, impairing the liquidation rights of our common stock, or delaying, deferring or preventing a

 
 
 
 
 
 
 
 
 
change in control of our company, which might harm the market price of our common stock. See also the “—Anti-Takeover Effects of Delaware Law, Our
Amended and Restated Certificate of Incorporation and Our Amended and Restated By-Laws” section below.

Our board of directors will make any determination to issue such shares based on its judgment as to our company’s best interests and the best interests of
our stockholders. We have no shares of preferred stock outstanding.

Warrants

There are no warrants outstanding.

Anti-takeover effects of Delaware law, our amended and restated certificate of incorporation and our amended and restated by-laws

Our amended and restated certificate of incorporation and amended and restated by-laws include a number of provisions that may have the effect of
encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue
non-negotiated takeover attempts. These provisions include the items described below.

Board composition and filling vacancies

In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three classes serving three-year terms, with
one class being elected each year. Our amended and restated certificate of incorporation also provides that directors may be removed only for cause and
then only by the affirmative vote of the holders of 75% or more of the shares then entitled to vote at an election of directors. Furthermore, any vacancy on
our board of directors, however occurring, including a vacancy resulting from an increase in the size of our board of directors, may only be filled by the
affirmative vote of a majority of our directors then in office, even if less than a quorum.

No written consent of stockholders

Our amended and restated certificate of incorporation provides that all stockholder actions are required to be taken by a vote of the stockholders at an
annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting.

Meetings of stockholders

Our amended and restated by-laws provide that only a majority of the members of our board of directors then in office may call special meetings of
stockholders and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders. Our
amended and restated by-laws limit the business that may be conducted at an annual meeting of stockholders to those matters properly brought before the
meeting.

Advance notice requirements

Our amended and restated by-laws establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for
election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must
be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received
at our principal executive offices not less than 90 days or more than 120 days prior to the first anniversary date of the annual meeting for the preceding
year. The notice must contain certain information specified in the amended and restated by-laws. These provisions may have the effect of precluding the
conduct of certain business at a meeting if the proper procedures are not followed. These provisions may also discourage or deter a potential acquirer from
conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company.

Amendment to by-laws and certificate of incorporation

As required by the Delaware General Corporation Law, any amendment of our amended and restated certificate of incorporation must first be approved by
a majority of our board of directors and, if required by law or our amended and restated certificate of incorporation, thereafter be approved by a majority of
the outstanding shares entitled to vote on the amendment, and a majority of the outstanding shares of each class entitled to vote thereon as a class, except
that the amendment of the provisions relating to stockholder action, directors, limitation of liability, exclusive jurisdiction of Delaware Courts and the
amendment of our amended and restated by-laws and amended and restated certificate of incorporation must be approved by not less than 75% of the
outstanding shares entitled to vote on the amendment, and not less than 75% of the outstanding shares of each class entitled to vote thereon as a class. Our
amended and restated by-laws may be amended by the affirmative vote of a majority of the directors then in office, subject to any limitations set forth in the
amended and restated by-laws; and may also be amended by the affirmative vote of at least 75% of the outstanding shares

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
entitled to vote on the amendment, or, if the board of directors recommends that the stockholders approve the amendment, by the affirmative vote of the
majority of the outstanding shares entitled to vote on the amendment, in each case voting together as a single class.

Blank check preferred stock

Our amended and restated certificate of incorporation provides for 5,000,000 authorized shares of preferred stock. The existence of authorized but unissued
shares of preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a
merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our board of directors were to determine
that a takeover proposal is not in the best interests of us or our stockholders, our board of directors could cause shares of preferred stock to be issued
without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights of the proposed acquirer or
insurgent stockholder or stockholder group. In this regard, our amended and restated certificate of incorporation grants our board of directors broad power
to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease the
amount of earnings and assets available for distribution to holders of shares of common stock. The issuance may also adversely affect the rights and
powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

Section 203 of the Delaware General Corporation Law

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly-held Delaware
corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this stockholder
becomes an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes, among other
things, a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person
who, together with affiliates and associates, owns, or did own within three years prior to the determination of interested stockholder status, 15% or more of
the corporation’s voting stock.

Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following
conditions:

•

•

•

before the stockholder became interested, the board of directors approved either the business combination or the transaction that resulted in the
stockholder becoming an interested stockholder;
upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at
least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the
voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances; or
at or after the time the stockholder became interested, the business combination was approved by the board of directors of the corporation and
authorized at an annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock that is
not owned by the interested stockholder.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its
amended and restated certificate of incorporation or by-laws resulting from a stockholders’ amendment approved by at least a majority of the outstanding
voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or
prevented.

Exclusive jurisdiction of certain actions

Our amended and restated certificate of incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions
against our directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the
State of Delaware, unless we otherwise consent. Although we believe this provision benefits us by providing increased consistency in the application of
Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Nasdaq Global Select Market Listing

Our common stock is listed on The Nasdaq Global Select Market under the trading symbol “GTHX.”

MUTUAL TERMINATION, RELEASE, AND SETTLEMENT AGREEMENT

by and between

G1 THERAPEUTICS, INC.

and

BOEHRINGER INGELHEIM PHARMACEUTICALS, INC.

December 15, 2021

 
 
 
 
 
 
 
 
MUTUAL TERMINATION, RELEASE, AND SETTLEMENT AGREEMENT

This  Mutual  Termination,  Release,  and  Settlement  Agreement  (“Termination Agreement”),  effective  as  of  December
15,  2021  (“Termination  Agreement  Effective  Date”),  by  and  between  G1  Therapeutics,  Inc.  (“G1”),  and  Boehringer  Ingelheim
Pharmaceuticals, Inc. (“BI”), sets forth the mutual understanding and agreement of the Parties regarding the mutual termination of
the  Co-Promotion  Agreement,  dated  June  29,  2020,  entered  into  by  and  between  G1  and  BI  (the  “Co-Promotion
Agreement”).  G1 and BI are each referred to herein as a “Party”  and together as the  “Parties”.  Capitalized terms  used  in  this
Termination Agreement and not defined herein shall have the respective meanings ascribed to such terms in the Co-Promotion
Agreement.  If there is a conflict between the terms of this Termination Agreement and the Co-Promotion Agreement, the terms
of this Termination Agreement will govern.

As discussed, G1 and BI have decided to mutually terminate the Co-Promotion Agreement under certain agreed terms,

all as detailed below:

1.

Termination.  Notwithstanding any provisions of the Co-Promotion Agreement to the contrary (including Section
11.2 therein), the Co-Promotion Agreement is hereby terminated effective as of March 2, 2022 at 11:59 p.m. Eastern Standard Time
(the  “Termination  Effective  Date”).    The  Parties  agree  that  the  termination  will  be  characterized  as  a  mutual  termination,  not  a
termination for cause or convenience under Section 11.2 of the Co-Promotion Agreement.

2.

Payment  Obligations  Upon  Termination.    The  provisions  of  Section  11.3  of  the  Co-Promotion  Agreement  shall
apply  to  the  effect  of  termination  of  the  Co-Promotion  Agreement  pursuant  to  this  Termination  Agreement;  provided, however,  that
Section 11.3.3 and Section 11.3.4 of the Co-Promotion Agreement shall not apply to the termination of the Co-Promotion Agreement
pursuant to this Termination Agreement, and instead, the following payment terms upon termination shall apply:

(a) Within  [*  *  *]  days  after  the  Termination  Effective  Date,  G1  will  make  the  final  Annual  Floor  True-Up
payment to BI for the Contract Year ending on the Termination Effective Date.  For the avoidance of doubt,
this payment shall be in an amount sufficient to ensure that, between the Sales Payments made on a quarterly
basis and this final Annual Floor True-Up, BI has been paid a total of at least [* * *] in connection with the
first Contract Year. Other than the payment pursuant to this Section 2(a) of this Termination Agreement, G1’s
Annual Floor payment obligations shall end as of the Termination Effective Date.

(b) G1 will pay BI [* * *] of the Annual SCLC Net Sales during the period [* * *] through [* * *].

(c) G1 will pay BI [* * *] of the Annual SCLC Net Sales during the period [* * *] through [* * *].

For purposes of Section 2(b) and Section 2(c) above, G1 will provide  [* * *]  reports  and  make  [* * *] payments  to  BI  in  a  manner
consistent with the timing terms set forth in Section 6.4.1 of the Co-Promotion Agreement, but, for the avoidance of doubt, G1 will
have no obligation

2

 
 
 
 
 
 
 
 
to provide [* * *] estimates of Net Sales as set forth in Section 6.4.2, which obligation will terminate as of the Termination Effective
Date.  For the avoidance of doubt, the Parties agree that the payments described in Section 2 of this Termination Agreement are the
only amounts that G1 shall be obligated to pay to BI under the Co-Promotion Agreement after the Termination Effective Date, and no
additional amounts will be payable by G1 to BI under or in connection with the Co-Promotion Agreement, including as a result of the
termination thereof.

3.

Wire Instructions and Late Payments: All payments made pursuant to this Termination Agreement shall be made

by wire transfer in accordance with the following instructions:

Boehringer Ingelheim Pharmaceuticals Inc.
[* * *]
New York, NY
Account No.: [* * *]
ABA No. [* * *]
SWIFT Code: [* * *]

If BI does not receive payment of any sum due to it on or before 5:00 p.m. (Eastern Standard Time) on the due date, interest shall
thereafter accrue in accordance with Section 6.4.6 of the Co-Promotion Agreement until the remaining amount plus accrued interest is
paid in full. For the avoidance of doubt, any failure to pay any sum due under this Termination Agreement on or before 5:00 p.m.
(Eastern Standard Time) on the due date shall be considered a material breach of this Termination Agreement, unless prior to the due
date the Party that owes the sum in good faith submits the question of the amount of the sum owed to dispute resolution in accordance
with the procedures described in Section 11.

4.

Mutual Waiver of Audit Rights.  G1 agrees to waive and not to exercise its rights of inspection pursuant to Section
4.2.2 of the Co-Promotion Agreement. BI agrees to waive and not to exercise its rights of inspection pursuant to Section 6.7 of the Co-
Promotion  Agreement  for  the  Contract  Year  ending  [*  *  *].    For  the  avoidance  of  doubt,  BI  retains  and  may  exercise  all  rights  of
inspection pursuant to Section 6.7 of the Co-Promotion Agreement for the period from [* * *] to [* * *].

5.

Transition Plan; Wind-Down.  

5.1.

Notwithstanding  Section  11.3.6  of  the  Co-Promotion  Agreement,  commencing  upon  the
Termination Agreement Effective Date, the Parties will work diligently and in good faith to (a) wind-down BI’s performance of
the  Promotion  Services  and  the  Promotion  Plan,  and  (b)  develop  a  written  transition  plan  that  facilitates  an  organized  and
efficient  transition  of  the  Promotion  Services  or  other  activities  performed  by  BI  under  the  Co-Promotion  Agreement  so
that G1 and/or its designee may seamlessly take over such activities within the transition period provided in such plan
(“2022 Transition Plan”) and BI will be relieved of promotional duties with respect to accounts that are transitioned from BI to
G1.  The 2022 Transition Plan shall, without limitation,

3

 
 
 
 
 
 
 
include  the  introduction  of  key  customers  to  G1  and  an  orientation  briefing  on  customers  and  accounts  by  the
Oncology Sales Consultants in the Territory.  The Parties shall agree upon the 2022 Transition Plan no later than [* *
*], and the Parties shall commence implementation and performance of the 2022 Transition Plan no later than [* * *].  The 2022
Transition  Plan  shall  be  designed  to  minimize  disruption  of  the  ongoing  Promotion  Services  and  commercialization  of  the
Product in the Territory, each Party shall work diligently and in good faith to perform its obligations under the 2022 Transition
Plan and act in accordance with  the  2022 Transition  Plan,  and  each  Party  shall  be  responsible  for  its  own  costs  and  expenses
incurred in connection therewith.  

5.2.

The  Parties  acknowledge,  and  the  2022  Transition  Plan  shall  take  into  account,  that  G1
has begun to hire its own salesforce to promote COSELATM and that this added salesforce may impact BI’s ability to
meet any particular sales targets.  To the extent such G1 activities impair BI’s ability to meet its obligations under the
2022 Transition Plan, BI’s obligations to do so shall be waived. For the avoidance of doubt, the obligations set forth in this
Section 5 and the 2022 Transition Plan supersede and render moot the Parties’ obligations with respect to the obligations set forth
in  Section  4.1  of  the  Co-Promotion  Agreement,  including,  without  limitation,  the  Promotion  Services,  the  Promotion  Plan
(including  the  Sales  Plan  and  the  Market  Access  Plan),  and  the  Transition  Plan  set  forth  in  the  Co-Promotion  Agreement.  In
addition,  the  Parties  acknowledge  and  agree  that  BI  will  take  no  steps  to  reduce  the  size  or  composition  of  the  Oncology
Personnel  before  [*  *  *]  unless  otherwise  set  forth  in  the  2022  Transition  Plan.  For  the  avoidance  of  doubt,  the  voluntary
resignation  or  termination  for  cause  of  any  Oncology  Personnel  shall  not  constitute  a  failure  to  perform  under  the  2022
Transition  Plan  or  a  breach  of  the  any  contractual  or  other  obligation  of  BI,  including  without  limitation  this  Termination
Agreement.  The  Parties  also  acknowledge  and  agree  that  BI  will  set  compensation  for  its  Oncology  Sales  Consultants  in
accordance with Section 4.1.4 of the Co-Promotion Agreement until the Termination Effective Date, or as otherwise set forth in
the 2022 Transition Plan.

The  Alliance  Managers  shall  coordinate  the  Parties’  performance  of  the  2022  Transition  Plan,
and the JPC shall monitor and oversee, and provide a forum for discussing, the 2022 Transition Plan and BI’s wind-down and
transition activities.

5.3.

6.

Surviving Rights and Obligations.  Except as provided in Sections 2 and 5 above and in Section 9 below, the
Parties are not relieved of their surviving obligations set forth in the second sentence of Section 11.3.5 of the Co-Promotion
Agreement (the “Surviving Rights and Obligations”) after the Termination Effective Date.

7.

Pharmacovigilance  Agreement.    The  Parties  hereby  terminate,  as  of  the  Termination  Effective  Date,  the

Pharmacovigilance Agreement entered into by them dated [* * *].

4

 
 
 
 
 
 
8.

Public Statements or Disclosures; Press Release.  

8.1.

This  Termination  Agreement  and  its  terms  shall  be  deemed  to  be  Confidential  Information  of
both Parties, and each Party agrees not to disclose any of them without the prior written consent of the other Party, except that
each Party may disclose any of them in accordance with the provisions of Article 8 of the Co-Promotion Agreement and Section
8.2 and Section 8.3 of this Termination Agreement.

8.2.

Without  limiting  either  Party’s  obligation  to  comply  with  the  terms  of  Article  8  of  the
Co-Promotion  Agreement,  each  Party  agrees  that  it  will  not  issue  any  press  release  or  other  public  statement  with
respect to the Co-Promotion Agreement or this Termination Agreement that disparages the other Party in any manner
reasonably likely to be harmful to the other Party; provided that each Party may make such disclosures regarding the
Co-Promotion  Agreement  and  this  Termination  Agreement  as  such  Party  believes,  with  the  advice  of  counsel,  are
reasonably  necessary  to  comply  with  Applicable  Laws,  including  regulations  promulgated  by  applicable
Governmental  Authorities,  securities  exchanges,  court  order,  administrative  subpoena,  or  other  legal  process.    In
addition, each Party hereby represents, warrants and covenants to the other Party that such Party will [* * *].

8.3.

As of the Termination Agreement Effective Date, (a) the Parties will work diligently and in good
faith to develop a mutually acceptable press release, or (b) if elected by either Party, the Parties may issue separate press releases, in
each case with respect to the termination of the Co-Promotion Agreement; provided that the content of any such press releases must
be consented to by the other Party prior to the issuance thereof, such consent not to be unreasonably withheld or delayed.  For clarity,
the Parties agree that after a press release is issued pursuant to this Section 8.3, the Parties may subsequently make public disclosures
of the same content without having to again follow the consent procedures herein; provided such content remains accurate as of such
time.  Each Party agrees that it shall cooperate fully with the other Party with respect to all disclosures regarding this Termination
Agreement to the Securities and Exchange Commission and any other Governmental Authorities, including requests for confidential
treatment of proprietary information of either Party included in any such disclosure.  In all other cases, each Party agrees not to, and
agrees to cause its Affiliates not to, issue any additional press release or make any other public statement or disclosure regarding this
Termination Agreement, the activities hereunder, or the transactions contemplated hereby, except in accordance with Article 8 of the
Co-Promotion Agreement.

9.

Mutual Release.  

9.1.

Each Party, for itself and its past and present Affiliates and its and their respective successors and

Dispute  Resolution.    If  a  dispute  arises  between  the  Parties  in  connection  with  or  relating  to  this  Termination

faith to resolve the Dispute,

6

 
 
 
 
 
including through discussions between the Senior Officers of the Parties.  Unless otherwise agreed to at the time, if these good-faith
efforts fail to resolve any such Dispute within [* * *] days of the initiation of the discussions related to the Dispute, then the Dispute
shall be submitted to and finally settled by binding arbitration by JAMS under its Comprehensive Arbitration Rules and Procedures.  A
Dispute settled  by  an  arbitrator  shall  be  conducted  by  [*  *  *]  arbitrators,  each  having  ten  years  of  experience  in  the  pharmaceutical
industry and also shall have served as an arbitrator at least three times prior to their service as an arbitrator in this arbitration.  Within [*
* *] of commencement of an arbitration each Party shall select [* * *] arbitrator and together select a [* * *] arbitrator who shall serve as
a neutral arbitrator.  The [* * *] designated arbitrators shall select a [* * *] neutral arbitrator within [* * *] of their selection if the Parties
cannot agree on the [* * *] arbitrator.  If the  [* * *]  arbitrators  cannot  agree  on  selection  of  a  [*  *  *] arbitrator within [*  *  *]  of their
appointment, JAMS shall do so in accordance with its rules.  The fees of the arbitrator(s) and JAMS shall be paid by the losing Party,
which shall be designated by the arbitrator(s).  If the arbitrator(s) is unable to designate a losing Party, it shall so state and the fees shall
be  split  equally  by  the  Parties.    The  arbitrator(s)  is  hereby  empowered  to  award  any  monetary  remedy  allowed  by  Applicable  Law,
including  money  damages,  prejudgment  interest  and  attorneys’  fees,  and  to  grant  final,  complete,  interim  or  interlocutory  relief,
provided  the  arbitrator(s)  shall  not  be  permitted  to  award  any  equitable  remedies,  including  injunctive  relief.    Notwithstanding  any
provision of this Agreement to the contrary, the Parties reserve the right to (a) pursue actions of equitable remedies, including injunctive
relief, exclusively in the  federal  and  state  courts  located  in  Wilmington,  Delaware,  including  actions  for  the  purposes  of  an  order  to
compel arbitration, for preliminary relief in aid of arbitration and for injunctive or equitable relief to maintain the status quo or prevent
irreparable  harm  prior  to  the  appointment  of  the  arbitrators,  and  (b)  to  pursue  actions  for  the  enforcement  of  any  monetary  remedy
issued pursuant to this Section 11 in any court of competent jurisdiction in the Territory.

12.

No Admission of Liability.  Each of the Parties agrees and acknowledges that nothing in this Termination
Agreement and no act of any Party shall be treated in any way as an admission of liability as to any claim, contention or
cause of action, and that this Termination Agreement is governed by Rule 408 of the Federal Rules of Evidence and similar
state law.

13.

Miscellaneous:  The  terms  of  this  Termination  Agreement  and  the  Co-Promotion  Agreement  constitute  the  sole
and  entire  agreement  between  the  Parties  with  respect  to  the  subject  matter  contained  herein  and  supersede  all  prior  and
contemporaneous  understandings,  agreements,  representations,  and  warranties.  In  addition,  this  Termination  Agreement  will  be
governed by, enforced, and construed in accordance with the laws of Delaware without regard to any conflicts of law provisions. This
Termination Agreement may be executed in counterparts with the same effect as if all Parties had signed the same document.  All such
counterparts  will  be  deemed  an  original,  will  be  construed  together,  and  will  constitute  one  and  the  same  instrument.    Any  such
counterpart, to the extent delivered by means of a fax machine or by .pdf, .tif, .gif, .jpeg or similar attachment to electronic mail (any
such delivery, an “Electronic Delivery”) will be treated in all respects as an original executed counterpart and will be considered to have
the  same  binding  legal  effect  as  if  it  were  the  original  signed  version  thereof  delivered  in  person.    No  Party  will  raise  the  use  of
Electronic Delivery to deliver a

7

 
 
 
 
signature  or  the  fact  that  any  signature  or  agreement  or  instrument  was  transmitted  or  communicated  through  the  use  of  Electronic
Delivery as a defense to the formation of a contract, and each Party forever waives any such defense, except to the extent that such
defense relates to lack of authenticity.  This Termination Agreement may be amended, or any term hereof modified or waived, only by a
written instrument duly executed by authorized representatives of the Parties.  This Termination Agreement shall be binding upon
and shall inure to the benefit of the heirs, executors, administrators, trustees, beneficiaries, successors, representatives and
assigns of the undersigned Parties.  If any provision of this Termination Agreement or the application thereof is held invalid,
the  invalidity  shall  not  affect  other  provisions  or  applications  of  this  Termination  Agreement  which  can  be  given  effect
without the invalid provisions or application, and to this end, the provisions of this Termination Agreement are declared to
be severable.

Ladies and Gentlemen:

COMMON STOCK
(par value $0.0001 per share)

SALES AGREEMENT

Exhibit 10.29

Execution Version

February 23, 2022

G1 Therapeutics, Inc., a Delaware corporation (the “Company”), confirms its agreement (this “Agreement”) with Cowen and Company, LLC

(“Cowen”), as follows:

1. Issuance and Sale of Shares. The Company agrees that, from time to time during the term of this Agreement, on the terms and subject to the
conditions set forth herein, it may issue and sell through Cowen, acting as agent and/or principal, shares (the “Placement Shares”) of the Company’s
common stock, par value $0.0001 per share (the “Common Stock”), having an aggregate offering price of up to $100,000,000. Notwithstanding anything
to the contrary contained herein, the parties hereto agree that compliance with the limitation set forth in this Section 1 on the number of shares of Common
Stock issued and sold under this Agreement shall be the sole responsibility of the Company, and Cowen shall have no obligation in connection with such
compliance. The issuance and sale of Common Stock through Cowen will be effected pursuant to the Registration Statement (as defined below) to be filed
by the Company and after such Registration Statement has been declared effective under the Securities Act (as defined below) with the Securities and
Exchange Commission (the “Commission”), although nothing in this Agreement shall be construed as requiring the Company to use the Registration
Statement (as defined below) to issue the Placement Shares. The Registration Statement will be a “shelf” registration statement and the Placement Shares
have been and remain eligible for registration by the Company on such shelf registration statement.

The Company has filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder

(collectively, the “Securities Act”), with the Commission a registration statement on Form S-3ASR (File No. 333-257640), including a base prospectus,
relating to certain securities, including the Common Stock, to be issued from time to time by the Company, and which incorporates by reference documents
that the Company has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder (collectively, the “Exchange Act”). Such registration statement and an automatic post-effective amendment thereto on Form POSASR filed on
February 23, 2022 became effective on filing, and a post-effective amendment to such registration statement on Form POS AM requesting that the
registration statement be converted to a non-automatic shelf registration statement was filed on February 23, 2022. The Company has prepared a prospectus
or a prospectus supplement to the base prospectus included as part of the registration statement, which prospectus or prospectus supplement relates to the
Placement Shares to be issued from time to time by the Company  (the “Prospectus Supplement”). The Company will file a final form of such Prospectus
Supplement pursuant to Rule 424(b) under the Securities Act.  Following the date that such registration statement is declared effective, the Company will
furnish to Cowen, for use by Cowen, copies of the prospectus included as part of such registration statement, as supplemented by the Prospectus
Supplement, relating to the Placement Shares. Except where the context otherwise requires, such registration statement, and any post-effective amendment
thereto, as amended when it becomes effective, including all documents filed as part thereof or incorporated by reference therein, and including any
information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act
Regulations or deemed to be a part of such registration statement pursuant to Rule 430B or 462(b) of the Securities Act, or any subsequent registration
statement on Form S-3 filed pursuant to Rule 415(a)(6) under the Securities Act by the Company with respect to the Placement Shares, of the Securities
Act, is herein called the “Registration Statement.” The base prospectus, including all documents incorporated therein by reference, included in the
Registration Statement, as it may be supplemented by the Prospectus Supplement, in the form in which such prospectus and/or Prospectus

 
 
Supplement have most recently been filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act Regulations, together
with any “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act (“Rule 433”), relating to the Placement Shares that (i) is
consented to by Cowen, hereinafter referred to as a “Permitted Free Writing Prospectus,” (ii) is required to be filed with the Commission by the
Company or (iii) is exempt from filing pursuant to Rule 433(d)(5)(i), in each case in the form filed or required to be filed with the Commission or, if not
required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g), is herein called the “Prospectus.” Any reference herein to the
Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the documents incorporated by
reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the
Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated
by reference therein. For purposes of this Agreement, all references to the Registration Statement, the Prospectus or to any amendment or supplement
thereto shall be deemed to include any copy filed with the Commission pursuant to the Electronic Data Gathering Analysis and Retrieval System
(“EDGAR”).

2. Placements. Each time that the Company wishes to issue and sell the Placement Shares hereunder (each, a “Placement”), it will notify Cowen

by email notice (or other method mutually agreed to in writing by the parties) (a “Placement Notice”) containing the parameters in accordance with which
it desires the Placement Shares to be sold, which shall at a minimum include the number of Placement Shares to be issued, the time period during which
sales are requested to be made, any limitation on the number of Placement Shares that may be sold in any one Trading Day (as defined in Section 3) and
any minimum price below which sales may not be made, a form of which containing such minimum sales parameters necessary is attached hereto as
Schedule 1. The Placement Notice shall originate from any of the individuals from the Company set forth on Schedule 2 (with a copy to each of the other
individuals from the Company listed on such schedule), and shall be addressed to each of the individuals from Cowen set forth on Schedule 2, as such
Schedule 2 may be amended from time to time. The Placement Notice shall be effective upon receipt by Cowen unless and until (i) in accordance with the
notice requirements set forth in Section 4, Cowen declines to accept the terms contained therein for any reason, in its sole discretion, (ii) the entire amount
of the Placement Shares have been sold, (iii) in accordance with the notice requirements set forth in Section 4, the Company suspends or terminates the
Placement Notice for any reason in its sole discretion, (iv) the Company issues a subsequent Placement Notice with parameters superseding those on the
earlier dated Placement Notice, or (v) this Agreement has been terminated under the provisions of Section 11. The amount of any discount, commission or
other compensation to be paid by the Company to Cowen in connection with the sale of the Placement Shares shall be calculated in accordance with the
terms set forth in Schedule 3. It is expressly acknowledged and agreed that neither the Company nor Cowen will have any obligation whatsoever with
respect to a Placement or any Placement Shares unless and until the Company delivers a Placement Notice to Cowen and Cowen does not decline such
Placement Notice pursuant to the terms set forth above, and then only upon the terms specified therein and herein. In the event of a conflict between the
terms of this Agreement and the terms of a Placement Notice, the terms of the Placement Notice will control.

3. Sale of Placement Shares by Cowen. Subject to the terms and conditions herein set forth, upon the Company’s delivery of a Placement Notice,
and unless the sale of the Placement Shares described therein has been declined, suspended, or otherwise terminated in accordance with the terms of this
Agreement, Cowen, for the period specified in the Placement Notice, will use its commercially reasonable efforts consistent with its normal trading and
sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq Global Select Market LLC (“Nasdaq”) to sell such
Placement Shares up to the amount specified in the Placement Notice, and otherwise in accordance with the terms of such Placement Notice. Cowen will
provide written confirmation to the Company (including by email correspondence to each of the individuals of the Company set forth on Schedule 2, if
receipt of such correspondence is actually acknowledged by any of the individuals to whom the notice is sent, other than via auto-reply) no later than the
opening of the Trading Day (as defined below) immediately following the Trading Day on which it has made sales of Placement Shares hereunder setting
forth the number of Placement Shares sold on such day, the volume-weighted average price of the Placement Shares sold, and the Net Proceeds (as defined
below) payable to the Company. In the event the Company engages Cowen for a sale of Placement Shares that would constitute a “block” within the
meaning of Rule 10b-18(a)(5) under the Exchange Act (a “Block Sale”), the Company will provide Cowen, at Cowen’s request and upon reasonable
advance notice to the Company, on or prior to the Settlement Date (as defined below), the opinions of counsel, accountants’ letter and officers’ certificates
set forth in Section 8 hereof, each dated the Settlement Date, and such other documents and information as Cowen

 
 
shall reasonably request. Cowen may sell Placement Shares by any method permitted by law deemed to be an “at the market” offering as defined in Rule
415 of the Securities Act, including without limitation sales made through Nasdaq or on any other existing trading market for the Common Stock.
Notwithstanding the provisions of Section 6(ii), Cowen shall not purchase Placement Shares for its own account as principal unless expressly authorized to
do so by the Company in a Placement Notice. The Company acknowledges and agrees that (i) there can be no assurance that Cowen will be successful in
selling Placement Shares, and (ii) Cowen will incur no liability or obligation to the Company or any other person or entity if it does not sell Placement
Shares for any reason other than a failure by Cowen to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell
such Placement Shares as required under this Section 3. For the purposes hereof, “Trading Day” means any day on which the Company’s Common Stock
is purchased and sold on Nasdaq.

Notwithstanding any other provision of this Agreement, the Company shall not offer, sell or deliver, or request the offer or sale of, any Placement

Shares pursuant to this Agreement and, by notice to Cowen given by telephone (confirmed promptly by email), shall cancel any instructions for the offer or
sale of any Placement Shares, and Cowen shall not be obligated to offer or sell any Placement Shares, (i) during any period in which the Company is, or
could be deemed to be, in possession of material non-public information, or (ii) at any time from and including the date on which the Company shall issue a
press release containing, or shall otherwise publicly announce, its earnings, revenues or other results of operations (an “Earnings Announcement”)
through and including the time that the Company files a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated
financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement.

4. Suspension of Sales.

(a) The Company or Cowen may, upon notice to the other party in writing (including by email correspondence to each of the individuals of the

other party set forth on Schedule 2, if receipt of such correspondence is actually acknowledged by any of the individuals to whom the notice is sent, other
than via auto-reply) or by telephone (confirmed immediately by verifiable facsimile transmission or email correspondence to each of the individuals of the
other party set forth on Schedule 2), suspend any sale of Placement Shares; provided, however, that such suspension shall not affect or impair either party’s
obligations with respect to any Placement Shares sold hereunder prior to the receipt of such notice. Each of the parties agrees that no such notice under this
Section 4 shall be effective against the other unless it is made to one of the individuals named on Schedule 2 hereto, as such schedule may be amended in
writing from time to time.

(b) If either Cowen or the Company has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the

Exchange Act are not satisfied with respect to the Common Stock, it shall promptly notify the other party, and Cowen may, at its sole discretion, suspend
sales of the Placement Shares under this Agreement.

(c) Notwithstanding any other provision of this Agreement, during any period in which the Registration Statement is no longer effective under the

Securities Act, the Company shall promptly notify Cowen, the Company shall not request the sale of any Placement Shares, and Cowen shall not be
obligated to sell or offer to sell any Placement Shares.

5. Settlement.

(a) Settlement of Placement Shares. Unless otherwise specified in the applicable Placement Notice, settlement for sales of Placement Shares will

occur on the second (2nd) Trading Day (or such earlier day as is industry practice for regular-way trading) following the date on which such sales are made
(each, a “Settlement Date” and the first such settlement date, the “First Delivery Date”). The amount of proceeds to be delivered to the Company on a
Settlement Date against receipt of the Placement Shares sold (the “Net Proceeds”) will be equal to the aggregate sales price received by Cowen at which
such Placement Shares were sold, after deduction for (i) Cowen’s commission, discount or other compensation for such sales payable by the Company
pursuant to Section 2 hereof, (ii) any other amounts due and payable by the Company to Cowen hereunder pursuant to Section 7(g) (Expenses) hereof, and
(iii) any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales.

 
 
(b) Delivery of Placement Shares. On or before each Settlement Date, the Company will, or will cause its transfer agent to, electronically transfer

the Placement Shares being sold by crediting Cowen’s or its designee’s account (provided Cowen shall have given the Company written notice of such
designee at least one Trading Day prior to the Settlement Date) at The Depository Trust Company through its Deposit and Withdrawal at Custodian System
or by such other means of delivery as may be mutually agreed upon by the parties hereto which in all cases shall be freely tradeable, transferable, registered
shares in good deliverable form. On each Settlement Date, Cowen will deliver the related Net Proceeds in same day funds to an account designated by the
Company on, or prior to, the Settlement Date. The Company agrees that if the Company, or its transfer agent (if applicable), defaults in its obligation to
deliver duly authorized Placement Shares on a Settlement Date, through no fault of Cowen, the Company agrees that in addition to and in no way limiting
the rights and obligations set forth in Section 9(a) (Indemnification and Contribution) hereto, it will (i) hold Cowen harmless against any loss, claim,
damage, or reasonable and documented expense (including reasonable and documented legal fees and expenses), as incurred, arising out of or in
connection with such default by the Company and (ii) pay to Cowen (without duplication) any commission, discount, or other compensation to which it
would otherwise have been entitled absent such default.

6. Representations and Warranties of the Company. Except as disclosed in the Registration Statement or the Prospectus, the Company represents

and warrants to, and agrees with, Cowen that as of the date of this Agreement, unless such representation or warranty specifies a different time, each
Representation Date (as defined in Section 6(m)), each date on which a Placement Notice is given, and any date on which Placement Shares are sold
hereunder:

(a) Compliance with Registration Requirements. The Registration Statement and any Rule 462(b) Registration Statement shall have been declared
effective by the Commission under the Securities Act. The Company has complied, to the Commission’s satisfaction, with all requests of the Commission
for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration
Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Company, contemplated or
threatened by the Commission. The Company meets the requirements for use of Form S-3 under the Securities Act. The sale of the Placement Shares
hereunder meets the requirements of General Instruction I.B.1 of Form S-3.

(b) No Misstatement or Omission. The Prospectus when filed, complied and, as amended or supplemented, if applicable, will comply in all material

respects with the Securities Act. Each of the Registration Statement, any Rule 462(b) Registration Statement, the Prospectus and any post-effective
amendments or supplements thereto, at the time it was declared effective or its date, as applicable, complied and as of each of the Settlement Dates, if any,
complied and will comply in all material respects with the Securities Act and did not and, as of each Settlement Date, if any, did not and will not contain
any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not
misleading. The Prospectus, as amended or supplemented, as of its date, did not and, as of each of the Settlement Dates, if any, did not and will not contain
any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading. The representations and warranties set forth in the two immediately preceding sentences do not apply to
statements in or omissions from the Registration Statement, any Rule 462(b) Registration Statement, or any post-effective amendment thereto, or the
Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with the Agent’s Information (as defined below). There
are no contracts or other documents required to be described in the Prospectus or to be filed as exhibits to the Registration Statement which have not been
described or filed as required.

(c) Offering Materials Furnished to Cowen. The Company has delivered to Cowen one complete copy of the Registration Statement and a copy of
each consent and certificate of experts filed as a part thereof, and conformed copies of the Registration Statement (without exhibits) and the Prospectus, as
amended or supplemented, in such quantities and at such places as Cowen has reasonably requested. The Registration Statement, the Prospectus and any
Permitted Free Writing Prospectus (to the extent any such Permitted Free Writing Prospectus was required to be filed with the Commission) delivered to
Cowen for use in connection with the public offering of the Placement Shares contemplated herein have been and will be identical to the versions of such
documents transmitted to the Commission for filing via EDGAR, except to the extent permitted by Regulation S-T.

 
 
(d) Not an Ineligible Issuer. The Company currently is not an “ineligible issuer,” as defined in Rule 405 promulgated under the Securities Act. The

Company agrees to notify Cowen promptly if it becomes an “ineligible issuer.”

(e) Distribution of Offering Material By the Company. The Company has not distributed and will not distribute, prior to the completion of Cowen’s

distribution of the Placement Shares pursuant to this Agreement, any offering material in connection with the offering and sale of the Placement Shares
other than the Prospectus or the Registration Statement.

(f) The Sales Agreement. This Agreement has been duly authorized, executed and delivered by, and is a valid and binding agreement of, the
Company, enforceable in accordance with its terms, except as rights to indemnification hereunder may be limited by applicable law and except as the
enforcement hereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles.

(g) Authorization of the Placement Shares. The Placement Shares, when issued and delivered, will be duly authorized for issuance and sale
pursuant to this Agreement and, when issued and delivered by the Company against payment therefor pursuant to this Agreement, will be duly authorized,
validly issued, fully paid and non-assessable, free and clear of any pledge, lien, encumbrance, security interest or other claim, and the issuance and sale of
the Placement Shares by the Company is not subject to preemptive or other similar rights, in each case arising by operation of law, under the organizational
documents of the Company or under any agreement to which the Company or any subsidiary is a party.

(h) No Applicable Registration or Other Similar Rights. There are no persons with registration or other similar rights to have any equity or debt
securities registered for sale under the Registration Statement or included in the offering contemplated by this Agreement, except for such rights as have
been duly waived.

(i) No Material Adverse Change. Except as otherwise disclosed in the Prospectus, subsequent to the respective dates as of which information is

given in the Prospectus: (i) there has been no material adverse change, or any development that could reasonably be expected to result in a material adverse
change, in the condition, financial or otherwise, or in the earnings, business, operations or prospects, whether or not arising from transactions in the
ordinary course of business, of the Company and its subsidiaries, considered as one entity (any such change is called a “Material Adverse Change”); (ii)
the Company and its subsidiaries, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, not in the
ordinary course of business nor entered into any material transaction or agreement not in the ordinary course of business: and (iii) there has been no
dividend or distribution of any kind declared, paid or made by the Company or, except for regular quarterly dividends publicly announced by the Company
or dividends paid to the Company or other subsidiaries, by any of its subsidiaries on any class of capital stock or repurchase or redemption by the Company
or any of its subsidiaries of any class of capital stock, except for repurchases of unvested Common Shares from terminated employees or consultants.

(j) Independent Accountants. PricewaterhouseCoopers LLP, who has expressed its opinion with respect to the financial statements (which term as

used in this Agreement includes the related notes thereto) filed with the Commission or incorporated by reference as a part of the Registration Statement
and included in the Prospectus, is an independent registered public accounting firm as required by the Securities Act and the Exchange Act.

(k) Preparation of the Financial Statements. The financial statements filed with the Commission as a part of or incorporated by reference in the
Registration Statement and included in the Prospectus present fairly, in all material respects, the consolidated financial position of the Company and its
subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified. The supporting schedules included
in or incorporated in the Registration Statement present fairly the information required to be stated therein. Such financial statements and supporting
schedules have been prepared in conformity with generally accepted accounting principles as applied in the United States applied on a consistent basis
throughout the periods involved, except as may be expressly stated in the related notes thereto. No other financial statements or supporting schedules are
required to be included in or incorporated in the Registration Statement.

 
 
 
(l) XBRL. The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement

authorized by all necessary corporate action and will not result in any violation of the provisions of the charter or by-laws of the Company or any

(p) No Material Actions or Proceedings. Except as disclosed in the Prospectus, there are no legal or governmental actions, suits or proceedings
pending or, to the best of the Company’s knowledge, threatened against or affecting the Company or any of its subsidiaries, where in any such case (A)
there is a reasonable possibility that such action, suit or proceeding might be determined adversely to the Company or such subsidiary and (B) any such
action, suit or proceeding, if so determined adversely, would reasonably be expected to result in a Material Adverse

local governmental or regulatory authority performing functions similar to those performed by the FDA) that are necessary for the ownership or lease of its
properties or the conduct of its business as described in the Prospectus (collectively, the “Governmental Permits”) except where any failures to possess or
make the same would not, singularly or in the aggregate, have a Material Adverse Change. The Company is in compliance with all such Governmental
Permits; all such Governmental Permits are valid and in full force and effect, except where the validity or failure to be in full force and effect would not,
singularly or in the aggregate, have a Material Adverse Change. All such Governmental Permits are free and clear of any restriction or condition that are in
addition to, or materially different from those normally applicable to similar licenses, certificates, authorizations and permits. The Company has not
received notification of any revocation, modification, suspension, termination or invalidation (or proceedings related thereto) of any such Governmental
Permit and no event has occurred that allows or results in, or after notice or lapse of time or both would allow or result in, revocation, modification,

coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its
business as now conducted and at a cost that would not result in a Material Adverse Change.

(u) No Price Stabilization or Manipulation. The Company has not taken and will not take, directly or indirectly, any action designed to or that

respect to any Intellectual Property Rights or Intellectual Property Assets owned or used by the Company. To the Company’s knowledge, the Company’s

of the business as currently conducted. With respect to the use of the software in the Company’s business as it is currently conducted,

be necessary or advisable in connection with the distribution of the Placement Shares by Cowen (provided, however, that the failure of Cowen to make
such request shall not relieve the Company of any obligation or liability hereunder, or affect Cowen’s right to rely on the representations and warranties
made by the Company in this Agreement; and provided, further, that the only remedy Cowen shall have with respect to the failure to make such filing will
be to cease making sales under this Agreement until such amendment or supplement is filed); (iii) the Company will not file any amendment or supplement
to the Registration Statement or Prospectus, other than documents incorporated by reference, relating to the Placement Shares or a security convertible into
the Placement Shares unless a copy thereof has been submitted to Cowen within a reasonable period of time before the filing and Cowen has not reasonably
objected in writing thereto (provided, however, that (A) the failure of Cowen to make such objection shall not relieve the Company of any obligation or
liability hereunder, or affect Cowen’s right to rely on the representations and warranties made by the Company in this Agreement and (B) the only remedy
Cowen shall have with respect to the failure by the Company to provide Cowen with such copy of the filing of such amendment or supplement despite
Cowen’s objection shall be to cease making sales under this Agreement) and the Company will furnish to Cowen at the time of filing thereof a copy of any
document that upon filing is deemed to be incorporated by reference into the Registration Statement or Prospectus, except for those documents available
via EDGAR; (iv) the Company will cause each amendment or supplement to the Prospectus, other than documents incorporated by reference, to be filed
with the Commission as required pursuant to the applicable paragraph of Rule 424(b) of the Securities Act, and (v) prior to the termination of this
Agreement, the Company will notify Cowen if at any time the Registration Statement shall no longer be effective as a result of the passage of time pursuant
to Rule 415 under the Securities Act or otherwise.

(b) Notice of Commission Stop Orders. The Company will advise Cowen, promptly after it receives notice or obtains knowledge thereof, of the

issuance or threatened issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, of the suspension of the
qualification of the Placement Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and
it will promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order should be
issued.

(c) Delivery of Prospectus; Subsequent Changes. During any period in which a Prospectus relating to the Placement Shares is required to be

delivered by Cowen under the Securities Act with respect to a pending sale of the Placement Shares, (including in circumstances where such requirement
may be satisfied pursuant to Rule 172 under the Securities Act), the Company will comply with all requirements imposed upon it by the Securities Act, as
from time to time in force, and to file on or before their respective due dates (taking into account any extensions available under the Exchange Act) all
reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Sections 13(a), 13(c), 14,
15(d) or any other provision of or under the Exchange Act. If during such period any event occurs as a result of which the Prospectus as then amended or
supplemented would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of
the circumstances then existing, not misleading, or if during such period it is necessary to amend or supplement the Registration Statement or Prospectus to
comply with the Securities Act, the Company will promptly notify Cowen to suspend the offering of Placement Shares during such period and the
Company will promptly amend or supplement the Registration Statement or Prospectus (at the reasonable expense of the Company) so as to correct such
statement or omission or effect such compliance; provided, however, that the Company may delay the filing of any amendment or supplement, if in the
judgment of the Company, it is in the best interests of the Company. Until such time as the Company shall have corrected such statement or omission or
effected such compliance, the Company shall not request that Cowen resume the offering of Placement Shares.

 
 
 
(d) Listing of Placement Shares. During any period in which the Prospectus relating to the Placement Shares is required to be delivered by Cowen

under the Securities Act with respect to a pending sale of the Placement Shares (including in circumstances where such requirement may be satisfied
pursuant to Rule 172 under the Securities Act), the Company will use its commercially reasonable efforts to cause the Placement Shares to be listed on
Nasdaq and to qualify the Placement Shares for sale under the securities laws of such jurisdictions as Cowen reasonably designates and to continue such
qualifications in effect so long as required for the distribution of the Placement Shares; provided, however, that the Company shall not be required in
connection therewith to qualify as a foreign corporation or dealer in securities or file a general consent to service of process in any jurisdiction.

(e) Delivery of Registration Statement and Prospectus. The Company will furnish to Cowen and its counsel (at the reasonable expense of the
Company) copies of the Registration Statement, the Prospectus (including all documents incorporated by reference therein) and all amendments and
supplements to the Registration Statement or Prospectus that are filed with the Commission during any period in which a Prospectus relating to the
Placement Shares is required to be delivered under the Securities Act (including all documents filed with the Commission during such period that are
deemed to be incorporated by reference therein), in each case as soon as reasonably practicable and in such quantities as Cowen may from time to time
reasonably request and, at Cowen’s request, will also furnish copies of the Prospectus to each exchange or market on which sales of the Placement Shares
may be made; provided, however, that the Company shall not be required to furnish any document (other than the Prospectus) to Cowen to the extent such
document is available on EDGAR.

(f) Earnings Statement. The Company will make generally available to its security holders as soon as practicable, via filing on EDGAR, but in any

event not later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement covering a 12-month period that satisfies the
provisions of Section 11(a) and Rule 158 of the Securities Act.

(g) Expenses. The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is terminated, in

accordance with the provisions of Section 11 hereunder, will pay the following expenses all incident to the performance of its obligations hereunder,
including, but not limited to, expenses relating to (i) the preparation, printing and filing of the Registration Statement and each amendment and supplement
thereto, of each Prospectus and of each amendment and supplement thereto, (ii) the preparation, issuance and delivery of the Placement Shares, (iii) the
qualification of the Placement Shares under securities laws in accordance with the provisions of Section 7(d) of this Agreement, including filing fees
(provided, however, that any fees or disbursements of counsel for Cowen in connection therewith shall be paid by Cowen except as set forth in (vii) below),
(iv) the printing and delivery to Cowen of copies of the Prospectus and any amendments or supplements thereto, and of this Agreement, (v) the fees and
expenses incurred in connection with the listing or qualification of the Placement Shares for trading on Nasdaq, (vi) the filing fees and expenses, if any, of
the Commission, (vii) the filing fees and associated legal expenses of Cowen’s outside counsel for filings with the FINRA Corporate Financing
Department, if any, such legal expense reimbursement not to exceed $10,000 and (viii) the reasonable fees and disbursements of Cowen’s counsel in an
amount not to exceed $50,000.

(h) Use of Proceeds. The Company will use the Net Proceeds as described in the Prospectus in the section entitled “Use of Proceeds.”

(i) Notice of Other Sales. During the pendency of any Placement Notice given hereunder, and for five (5) trading days following the termination of

any Placement Notice given hereunder, the Company shall provide Cowen notice as promptly as reasonably possible before it offers to sell, contracts to
sell, sells, grants any option to sell or otherwise disposes of any shares of Common Stock (other than Placement Shares offered pursuant to the provisions
of this Agreement) or securities convertible into or exchangeable for Common Stock, warrants or any rights to purchase or acquire Common Stock;
provided, that such notice shall not be required in connection with the (i) issuance, grant or sale of Common Stock, options to purchase shares of Common
Stock or Common Stock issuable upon the exercise of options or other equity awards pursuant to the any stock option, stock bonus or other stock plan or
arrangement described in the Prospectus, (ii) the issuance of securities in connection with an acquisition, merger or sale or purchase of assets or (iii) the
issuance or sale of Common Stock pursuant to any dividend reinvestment plan that the Company may adopt from time to time provided the implementation
of such is disclosed to Cowen in advance or (iv) any shares of common stock issuable upon the exchange, conversion or redemption of securities or the
exercise of warrants, options or other rights in effect or outstanding.

 
 
(j) Change of Circumstances. The Company will, at any time during a fiscal quarter in which the Company intends to tender a Placement Notice or
sell Placement Shares, advise Cowen promptly after it shall have received notice or obtained knowledge thereof, of any information or fact that would alter
or affect in any material respect any opinion, certificate, letter or other document provided to Cowen pursuant to this Agreement.

(k) Due Diligence Cooperation. During the term of this Agreement, the Company will cooperate with any reasonable due diligence review

conducted by Cowen or its agents in connection with the transactions contemplated hereby, including, without limitation, providing information and
making available documents and senior corporate officers, during regular business hours and at the Company’s principal offices, as Cowen may reasonably
request.

(l) Required Filings Relating to Placement of Placement Shares. The Company agrees that on such dates as the Securities Act shall require, the
Company will (i) file a prospectus supplement with the Commission under the applicable paragraph of Rule 424(b) under the Securities Act (each and
every filing under Rule 424(b), a “Filing Date”), which prospectus supplement will set forth, within the relevant period, the amount of Placement Shares
sold through Cowen, the Net Proceeds to the Company and the compensation payable by the Company to Cowen with respect to such Placement Shares,
and (ii) deliver such number of copies of each such prospectus supplement to each exchange or market on which such sales were effected as may be
required by the rules or regulations of such exchange or market. The Company shall disclose in its quarterly reports on Form 10-Q and in its annual report
on Form 10-K, the number of the Placement Shares sold through Cowen under this Agreement, and the gross proceeds and Net Proceeds to the Company
from the sale of the Placement Shares and the compensation paid by the Company with respect to sales of the Placement Shares pursuant to this Agreement
during the relevant quarter or, in the case of an Annual Report on Form 10-K, during the fiscal year covered by such Annual Report and the fourth quarter
of such fiscal year.

(m) Representation Dates; Certificate. During the term of this Agreement, on or prior to the First Delivery Date and each time the Company (i) files

the Prospectus relating to the Placement Shares or amends or supplements the Registration Statement or the Prospectus relating to the Placement Shares
(other than a prospectus supplement filed in accordance with Section 7(l) of this Agreement) by means of a post-effective amendment, sticker, or
supplement but not by means of incorporation of document(s) by reference to the Registration Statement or the Prospectus relating to the Placement
Shares; (ii) files an annual report on Form 10-K under the Exchange Act; (iii) files its quarterly reports on Form 10-Q under the Exchange Act; or (iv) files
a current report on Form 8-K containing amended financial information (other than information “furnished” pursuant to Items 2.02 or 7.01 of Form 8-K)
under the Exchange Act (each date of filing of one or more of the documents referred to in clauses (i) through (iv) shall be a “Representation Date”); the
Company shall furnish Cowen with a certificate, in the form attached hereto as Exhibit 7(m) within three (3) Trading Days of any Representation Date if
requested by Cowen. The requirement to provide a certificate under this Section 7(m) shall be automatically waived for any Representation Date occurring
at a time at which no Placement Notice is pending, which waiver shall continue until the earlier to occur of the date the Company delivers a Placement
Notice hereunder (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date; provided,
however, that such waiver shall not apply for any Representation Date on which the Company files its annual report on Form 10-K. Notwithstanding the
foregoing, if the Company subsequently decides to sell Placement Shares following a Representation Date when the Company relied on such waiver and
did not provide Cowen with a certificate under this Section 7(m), then before the Company delivers the Placement Notice or Cowen sells any Placement
Shares, the Company shall provide Cowen with a certificate, in the form attached hereto as Exhibit 7(m), dated the date of the Placement Notice.

(n) Legal Opinion. On or prior to the First Delivery Date and within three (3) Trading Days of each Representation Date with respect to which
the Company is obligated to deliver a certificate in the form attached hereto as Exhibit 7(m) for which no waiver is applicable, the Company shall cause to
be furnished to Cowen a written opinion of Mintz, Levin Cohn, Ferris, Glovsky and Popeo, P.C. (“Company Counsel”), or other counsel satisfactory to
Cowen, in form and substance satisfactory to Cowen and its counsel, dated the date that the opinion is required to be delivered, modified, as necessary, to
relate to the Registration Statement and the Prospectus as then amended or supplemented; provided, however, that in lieu of such opinions for subsequent
Representation Dates, Company Counsel may furnish Cowen with a letter (a “Reliance Letter”) to the effect that Cowen may rely on a prior opinion
delivered under this Section 7(n) to the same extent as if it were dated the date of such letter (except

 
 
 
 
that statements in such prior opinion shall be deemed to relate to the Registration Statement and the Prospectus as amended or supplemented at such
Representation Date).

(o) Comfort Letter. On or prior to the First Delivery Date and within three (3) Trading Days of each Representation Date with respect to which the

Company is obligated to deliver a certificate in the form attached hereto as Exhibit 7(m) for which no waiver is applicable, the Company shall cause its
independent accountants to furnish Cowen a letter (the “Comfort Letter”), dated the date the Comfort Letter is delivered, in form and substance
reasonably satisfactory to Cowen, (i) confirming that they are an independent registered public accounting firm within the meaning of the Securities Act
and the PCAOB, (ii) stating, as of such date, the conclusions and findings of such firm with respect to the financial information and other matters ordinarily
covered by accountants’ “comfort letters” to Cowen in connection with registered public offerings (the first such letter, the “Initial Comfort Letter”) and
(iii) updating the Initial Comfort Letter with any information that would have been included in the Initial Comfort Letter had it been given on such date and
modified as necessary to relate to the Registration Statement and the Prospectus, as amended and supplemented to the date of such letter.

(p) Market Activities. The Company will not, directly or indirectly, (i) take any action designed to cause or result in, or that constitutes or might

reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the
Placement Shares or (ii) sell, bid for, or purchase the Placement Shares to be issued and sold pursuant to this Agreement, or pay anyone any compensation
for soliciting purchases of the Placement Shares other than Cowen; provided, however, that the Company may bid for and purchase shares of its common
stock in accordance with Rule 10b-18 under the Exchange Act.

(q) Insurance. The Company and its subsidiaries shall maintain, or cause to be maintained, insurance in such amounts and covering such risks as is

reasonable and customary for the business for which it is engaged.

(r) Compliance with Laws. The Company and each of its subsidiaries shall maintain, or cause to be maintained, all material environmental permits,

licenses and other authorizations required by federal, state and local law in order to conduct their businesses as described in the Prospectus, and the
Company and each of its subsidiaries shall conduct their businesses, or cause their businesses to be conducted, in substantial compliance with such permits,
licenses and authorizations and with applicable environmental laws, except where the failure to maintain or be in compliance with such permits, licenses
and authorizations could not reasonably be expected to result in a Material Adverse Change.

(s) Investment Company Act. The Company will conduct its affairs in such a manner so as to reasonably ensure that neither it nor its subsidiaries
will be or become, at any time prior to the termination of this Agreement, an “investment company,” as such term is defined in the Investment Company
Act, assuming no change in the Commission’s current interpretation as to entities that are not considered an investment company.

(t) Securities Act and Exchange Act. The Company will use its best efforts to comply with all requirements imposed upon it by the Securities Act

and the Exchange Act as from time to time in force, so far as necessary to permit the continuance of sales of, or dealings in, the Placement Shares as
contemplated by the provisions hereof and the Prospectus.

(u) No Offer to Sell. Other than the Prospectus or a Permitted Free Writing Prospectus approved in advance by the Company and Cowen in its
capacity as principal or agent hereunder, neither Cowen nor the Company (including its agents and representatives, other than Cowen in its capacity as
such) will make, use, prepare, authorize, approve or refer to any written communication (as defined in Rule 405 under the Securities Act), required to be
filed with the Commission, that constitutes an offer to sell or solicitation of an offer to buy Placement Shares hereunder.

(v) Sarbanes-Oxley Act. The Company and its subsidiaries will use their best efforts to comply with all effective applicable provisions of the

Sarbanes-Oxley Act.

(w) Affirmation.  Each Placement Notice delivered by the Company to Cowen shall be deemed to be (i) an affirmation that the representations,

warranties and agreements of the Company herein contained and contained in any certificate delivered to Cowen pursuant hereto are true and correct at the
time of delivery of such Placement Notice, and (ii) an undertaking that such representations, warranties and agreements will be true and correct on any

 
 
 
applicable Time of Sale and Settlement Date, as though made at and as of each such time (it being understood that such representations, warranties and
agreements shall relate to the Registration Statement and the Prospectus as amended and supplemented to the time of such Placement Notice acceptance).

(x) Renewal. If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, the
aggregate gross sales price of Placement Shares sold by the Company is less than $100,000,000 and this Agreement has not expired or been terminated, the
Company may elect to file, prior to the Renewal Deadline, if it has not already done so and is eligible to do so, a new shelf registration statement relating to
the Placement Shares, in a form satisfactory to Cowen, and, if not automatically effective, will use its commercially reasonable efforts to cause such
registration statement to be declared effective within 60 days after the Renewal Deadline. The Company will take all other action necessary or appropriate
to permit the issuance and sale of the Placement Shares to continue as contemplated in the expired registration statement relating to the Placement Shares.
References herein to the Registration Statement shall include such new shelf registration statement.

8. Conditions to Cowen’s Obligations. The obligations of Cowen hereunder with respect to a Placement will be subject to the continuing accuracy
and completeness of the representations and warranties made by the Company herein, to the due performance by the Company of its obligations hereunder,
to the completion by Cowen of a due diligence review satisfactory to Cowen in its reasonable judgment, and to the continuing satisfaction (or waiver by
Cowen in its sole discretion) of the following additional conditions:

(a) Registration Statement Effective. The Registration Statement shall be effective and shall be available for (i) all sales of Placement Shares issued

pursuant to all prior Placement Notices and (ii) the sale of all Placement Shares contemplated to be issued by any Placement Notice.

(b) No Material Notices. None of the following events shall have occurred and be continuing: (i) receipt by the Company or any of its subsidiaries

of any request for additional information from the Commission or any other federal or state governmental authority during the period of effectiveness of the
Registration Statement, the response to which would require any post-effective amendments or supplements to the Registration Statement or the
Prospectus; (ii) the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose; (iii) receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Placement Shares for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose; or (iv) the occurrence of any event that makes any material statement made in the Registration Statement or the Prospectus or
any material document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any
changes in the Registration Statement, related Prospectus or such documents so that, in the case of the Registration Statement, it will not contain any
materially untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not
misleading and, that in the case of the Prospectus, it will not contain any materially untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(c) No Misstatement or Material Omission. Cowen shall not have advised the Company that the Registration Statement or Prospectus, or any
amendment or supplement thereto, contains an untrue statement of fact that in Cowen’s reasonable opinion is material, or omits to state a fact that in
Cowen’s opinion is material and is required to be stated therein or is necessary to make the statements therein not misleading.

(d) Material Changes. Except as contemplated in the Prospectus, or disclosed in the Company’s reports filed with the Commission, there shall not
have been any Material Adverse Change, on a consolidated basis, in the authorized capital stock of the Company or any Material Adverse Change or any
development that could reasonably be expected to result in a Material Adverse Change, or any downgrading in or withdrawal of the rating assigned to any
of the Company’s securities (other than asset backed securities) by any rating organization or a public announcement by any rating organization that it has
under surveillance or review its rating of any of the Company’s securities (other than asset backed securities), the effect of which, in the case of any such
action by a rating organization described above, in the reasonable judgment of Cowen (without relieving the Company of any

 
 
obligation or liability it may otherwise have), is so material as to make it impracticable or inadvisable to proceed with the offering of the Placement Shares
on the terms and in the manner contemplated in the Prospectus.

(e) Company Counsel Legal Opinion. Cowen shall have received the opinion of Company Counsel required to be delivered pursuant to Section

7(n) on or before the date on which such delivery of such opinion is required pursuant to Section 7(n).

(f) Cowen Counsel Legal Opinion. Cowen shall have received from DLA Piper LLP (US), counsel for Cowen, such opinion or opinions, on or

before the date on which the delivery of the Company Counsel legal opinion is required pursuant to Section 7(n), with respect to such matters as Cowen
may reasonably require, and the Company shall have furnished to such counsel such documents as they request for enabling them to pass upon such
matters.

(g) Comfort Letter. Cowen shall have received the Comfort Letter required to be delivered pursuant to Section 7(o) on or before the date on which

such delivery of such Comfort Letter is required pursuant to Section 7(o).

(h) Representation Certificate. Cowen shall have received the certificate required to be delivered pursuant to Section 7(m) on or before the date on

which delivery of such certificate is required pursuant to Section 7(m).

(i) Secretary’s Certificate. On or prior to the First Delivery Date, Cowen shall have received a certificate, signed on behalf of the Company by its

corporate Secretary, in form and substance satisfactory to Cowen and its counsel.

(j) No Suspension. Trading in the Common Stock shall not have been suspended on Nasdaq.

(k) Other Materials. On each date on which the Company is required to deliver a certificate pursuant to Section 7(m), the Company shall have

furnished to Cowen such appropriate further information, certificates and documents as Cowen may have reasonably requested. All such opinions,
certificates, letters and other documents shall have been in compliance with the provisions hereof. The Company will furnish Cowen with such conformed
copies of such opinions, certificates, letters and other documents as Cowen shall have reasonably requested.

(l) Securities Act Filings Made. All filings with the Commission required by Rule 424 under the Securities Act to have been filed prior to the

issuance of any Placement Notice hereunder shall have been made within the applicable time period prescribed for such filing by Rule 424.

(m) Approval for Listing. The Placement Shares shall either have been (i) approved for listing on Nasdaq, subject only to notice of issuance, or (ii)

the Company shall have filed an application for listing of the Placement Shares on Nasdaq at, or prior to, the issuance of any Placement Notice.

(n) No Termination Event. There shall not have occurred any event that would permit Cowen to terminate this Agreement pursuant to Section

11(a).

9. Indemnification and Contribution.

(a) Company Indemnification. The Company agrees to indemnify and hold harmless Cowen, the directors, officers, partners, employees and agents
of Cowen and each person, if any, who (i) controls Cowen within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or (ii)
is controlled by or is under common control with Cowen (a “Cowen Affiliate”) from and against any and all losses, claims, liabilities, reasonable and
documented expenses and damages (including, but not limited to, any and all reasonable and documented investigative, legal and other expenses incurred
in connection with, and any and all amounts paid in settlement (in accordance with Section 9(c)) of, any action, suit or proceeding between any of the
indemnified parties and any indemnifying parties or between any indemnified party and any third party, or otherwise, or any claim asserted), as and when
incurred, to which Cowen, or any such person, may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based, directly or indirectly, on
(x) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus or any amendment or
supplement to the Registration Statement or the Prospectus or in any free writing

 
 
 
prospectus or in any application or other document executed by or on behalf of the Company or based on written information furnished by or on behalf of
the Company filed in any jurisdiction in order to qualify the Common Stock under the securities laws thereof or filed with the Commission, (y) the
omission or alleged omission to state in any such document a material fact required to be stated in it or necessary to make the statements in it not
misleading or (z) any breach by any of the indemnifying parties of any of their respective representations, warranties and agreements contained in this
Agreement; provided, however, that this indemnity agreement shall not apply to the extent that such loss, claim, liability, expense or damage arises from the
sale of the Placement Shares pursuant to this Agreement and is caused directly or indirectly by an untrue statement or omission made in reliance upon and
in conformity with the Agent’s Information. This indemnity agreement will be in addition to any liability that the Company might otherwise have.

(b) Cowen Indemnification. Cowen agrees to indemnify and hold harmless the Company and its directors and each officer of the Company that

signed the Registration Statement, and each person, if any, who (i) controls the Company within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act or (ii) is controlled by or is under common control with the Company (a “Company Affiliate”) against any and all loss, liability,
claim, damage and expense described in the indemnity contained in Section 9(a), as incurred, but only with respect to untrue statements or omissions, or
alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto) or the Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with the Agent’s Information.

(c) Procedure. Any party that proposes to assert the right to be indemnified under this Section 9 will, promptly after receipt of notice of
commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 9,
notify each such indemnifying party in writing of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify
such indemnifying party will not relieve the indemnifying party from (i) any liability that it might have to any indemnified party otherwise than under this
Section 9 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section 9 unless, and only to the extent that,
such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified
party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by
delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly
with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and
after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the
indemnified party for any legal or other expenses except as provided below and except for the reasonable and documented costs of investigation
subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel
by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of
counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the
indemnifying party, (3) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the
indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or
(4) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the
commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the
indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the reasonable and documented fees, disbursements and other charges of more than one separate firm admitted to
practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by
the indemnifying party promptly after the indemnifying party receives a written invoice relating to fees, disbursements and other charges. An indemnifying
party will not, in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the
prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or
proceeding relating to the matters contemplated by this Section 9 (whether or not any indemnified party is a party thereto), unless such settlement,

 
 
compromise or consent includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or
proceeding.

(d) Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing

paragraphs of this Section 9 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or Cowen, the
Company and Cowen will contribute to the total losses, claims, liabilities, reasonable and documented expenses and damages (including any investigative,
legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted,
but after deducting any contribution received by the Company from persons other than Cowen, such as persons who control the Company within the
meaning of the Securities Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for
contribution) to which the Company and Cowen may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the
Company on the one hand and Cowen on the other. The relative benefits received by the Company on the one hand and Cowen on the other hand shall be
deemed to be in the same proportion as the total Net Proceeds from the sale of the Placement Shares (before deducting expenses) received by the Company
bear to the total compensation received by Cowen from the sale of Placement Shares on behalf of the Company. If, but only if, the allocation provided by
the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not
only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and Cowen, on the other, with
respect to the statements or omission that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant
equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or
Cowen, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The
Company and Cowen agree that it would not be just and equitable if contributions pursuant to this Section 9(d) were to be determined by pro rata allocation
or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an
indemnified party as a result of the loss, claim, liability, expense, or damage, or action in respect thereof, referred to above in this Section 9(d) shall be
deemed to include, for the purpose of this Section 9(d), any documented legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim to the extent consistent with Section 9(c) hereof. Notwithstanding the foregoing
provisions of this Section 9(d), Cowen shall not be required to contribute any amount in excess of the commissions received by it under this Agreement and
no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9(d), any person who controls a party to this Agreement
within the meaning of the Securities Act, and any officers, directors, partners, employees or agents of Cowen, will have the same rights to contribution as
that party, and each officer and director of the Company who signed the Registration Statement will have the same rights to contribution as the Company,
subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against
such party in respect of which a claim for contribution may be made under this Section 9(d), will notify any such party or parties from whom contribution
may be sought, but the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or
they may have under this Section 9(d) except to the extent that the failure to so notify such other party materially prejudiced the substantive rights or
defenses of the party from whom contribution is sought. Except for a settlement entered into pursuant to the last sentence of Section 9(c) hereof, no party
will be liable for contribution with respect to any action or claim settled without its written consent if such consent is required pursuant to Section 9(c)
hereof.

10. Representations and Agreements to Survive Delivery. The indemnity and contribution agreements contained in Section 9 of this Agreement and
all representations and warranties of the Company herein or in certificates delivered pursuant hereto shall survive, as of their respective dates, regardless of
(i) any investigation made by or on behalf of Cowen, any controlling persons, or the Company (or any of their respective officers, directors or controlling
persons), (ii) delivery and acceptance of the Placement Shares and payment therefor or (iii) any termination of this Agreement.

11. Termination.

 
 
(a) Cowen shall have the right by giving written notice as hereinafter specified at any time to terminate this Agreement if (i) any Material Adverse

Change, or any development that could reasonably be expected to result in a Material Adverse Change has occurred that, in the reasonable judgment of
Cowen, may materially impair the ability of Cowen to sell the Placement Shares hereunder, (ii) the Company shall have failed, refused or been unable to
perform any agreement on its part to be performed hereunder; provided, however, in the case of any failure of the Company to deliver (or cause another
person to deliver) any certification, opinion, or letter required under Sections 7(m), 7(n), or 7(o), Cowen’s right to terminate shall not arise unless such
failure to deliver (or cause to be delivered) continues for more than thirty (30) days from the date such delivery was required; or (iii) any other condition of
Cowen’s obligations hereunder is not fulfilled, or (iv), any suspension or limitation of trading in the Placement Shares or in securities generally on Nasdaq
shall have occurred. Any such termination shall be without liability of any party to any other party except that the provisions of Section 7(g) (Expenses),
Section 9 (Indemnification and Contribution), Section 10 (Representations and Agreements to Survive Delivery), Section 16 (Applicable Law; Consent to
Jurisdiction) and Section 17 (Waiver of Jury Trial) hereof shall remain in full force and effect notwithstanding such termination. If Cowen elects to
terminate this Agreement as provided in this Section 11(a), Cowen shall provide the required notice as specified in Section 12 (Notices).

(b) The Company shall have the right, by giving ten (10) days written notice as hereinafter specified to terminate this Agreement in its sole
discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the
provisions of Section 7(g), Section 9, Section 10, Section 16 and Section 17 hereof shall remain in full force and effect notwithstanding such termination.

(c) Cowen shall have the right, by giving ten (10) days’ notice as hereinafter specified to terminate this Agreement in its sole discretion at any time

after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the provisions of Section 7(g),
Section 9, Section 10, Section 16 and Section 17 hereof shall remain in full force and effect notwithstanding such termination.

(d) Unless earlier terminated pursuant to this Section 11, this Agreement shall automatically terminate upon the issuance and sale of all of the
Placement Shares through Cowen on the terms and subject to the conditions set forth herein; provided that the provisions of Section 7(g), Section 9, Section
10, Section 16 and Section 17 hereof shall remain in full force and effect notwithstanding such termination.

(e) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 11(a), (b), (c), or (d) above or otherwise by mutual

agreement of the parties; provided, however, that any such termination by mutual agreement shall in all cases be deemed to provide that Section 7(g),
Section 9, Section 10, Section 16 and Section 17 shall remain in full force and effect.

(f) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided, however, that such
termination shall not be effective until the close of business on the date of receipt of such notice by Cowen or the Company, as the case may be. If such
termination shall occur prior to the Settlement Date for any sale of Placement Shares, such Placement Shares shall settle in accordance with the provisions
of this Agreement.12. Notices. All notices or other communications required or permitted to be given by any party to any other party pursuant to the terms
of this Agreement shall be in writing, unless otherwise specified in this Agreement, and if sent to Cowen, shall be delivered to Cowen at Cowen and

13. Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the Company and Cowen and their respective

successors and the affiliates, controlling persons, officers and directors referred to in Section 9 hereof. References to any of the parties contained in this
Agreement shall be deemed to include the successors and permitted assigns of such party. Nothing in this Agreement, express or implied, is intended to
confer upon any party other than the parties hereto or their respective successors and permitted assigns any rights, remedies, obligations or liabilities under
or by reason of this Agreement, except as expressly provided in this Agreement. Neither party may assign its rights or obligations under this Agreement
without the prior written consent of the other party; provided, however, that Cowen may assign its rights and obligations hereunder to an affiliate of Cowen
without obtaining the Company’s consent.

14. Adjustments for Share Splits. The parties acknowledge and agree that all share-related numbers contained in this Agreement shall be adjusted

to take into account any share split, share dividend or similar event effected with respect to the Common Stock.

15. Entire Agreement; Amendment; Severability. This Agreement (including all schedules and exhibits attached hereto and Placement Notices

issued pursuant hereto) constitutes the entire agreement and supersedes all other prior and contemporaneous agreements and undertakings, both written and
oral, among the parties hereto with regard to the subject matter hereof. Neither this Agreement nor any term hereof may be amended except pursuant to a
written instrument executed by the Company and Cowen. In the event that any one or more of the provisions contained herein, or the application thereof in
any circumstance, is held invalid, illegal or unenforceable as written by a court of competent jurisdiction, then such provision shall be given full force and
effect to the fullest possible extent that it is valid, legal and enforceable, and the remainder of the terms and provisions herein shall be construed as if such
invalid, illegal or unenforceable term or provision was not contained herein, but only to the extent that giving effect to such provision and the remainder of
the terms and provisions hereof shall be in accordance with the intent of the parties as reflected in this Agreement.

16. Applicable Law; Consent to Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State

of New York without regard to the principles of conflicts of laws. Each party hereby irrevocably submits to the non-exclusive jurisdiction of the state and
federal courts sitting in the City of New York, borough of Manhattan, for the adjudication of any dispute hereunder or in connection with any transaction
contemplated hereby, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to
the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or
proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof (certified or registered mail, return receipt requested) to such party at the address in effect for notices to it under this
Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed
to limit in any way any right to serve process in any manner permitted by law.

17. Waiver of Jury Trial. The Company and Cowen each hereby irrevocably waives any right it may have to a trial by jury in respect of any claim

based upon or arising out of this Agreement or any transaction contemplated hereby.

18. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) Cowen has been retained solely to act as an arm’s length contractual counterparty to the Company in connection with the sale of the Placement
Shares contemplated hereby and that no fiduciary, advisory or agency relationship between the Company and Cowen has been created in respect of any of
the transactions contemplated by this Agreement, irrespective of whether Cowen has advised or is advising the Company on other matters;

(b) the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions

contemplated by this Agreement;

 
 
(c) the Company has been advised that Cowen and its affiliates are engaged in a broad range of transactions which may involve interests that differ

from those of the Company and that Cowen has no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary,
advisory or agency relationship; and

(d) the Company waives, to the fullest extent permitted by law, any claims it may have against Cowen, for breach of fiduciary duty or alleged

breach of fiduciary duty in connection with the sale of the Placement Shares under this Agreement and agrees that Cowen shall have no liability (whether
direct or indirect) to the Company in respect of such a fiduciary claim or to any person asserting a fiduciary duty claim on behalf of or in right of the
Company, including stockholders, partners, employees or creditors of the Company.

19. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. Delivery of an executed Agreement by one party to the other may be made by facsimile or electronic
transmission.

20. Recognition of the U.S. Special Resolution Regimes.  

In the event that Cowen is a Covered Entity and becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from

Cowen of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective
under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state
of the United States.

In the event that Cowen is a Covered Entity or a BHC Act Affiliate (as defined below) of Cowen becomes subject to a proceeding under a U.S.

Special Resolution Regime, Default Rights under this Agreement that may be exercised against Cowen are permitted to be exercised to no greater extent
than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or
a state of the United States.
