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. COSELA® (trilaciclib), our first product approved by the U.S. Food and Drug Administration (“FDA”), is the first and
only  therapy  indicated  to  proactively  help  protect  bone  marrow  (myeloprotection)  from  the  damage  of  chemotherapy  and  is  the  first  innovation  in
managing  myeloprotection  in  decades.  COSELA  (trilaciclib  hydrochloride  for  injection)  is  also  approved  by  the  China  National  Medical  Products
Administration  ("NMPA")  for  marketing  in  mainland  China  and  is  commercialized  by  our  partner,  Simcere  Pharmaceutical  Co.,  Ltd.  ("Simcere"),  in
Greater China (mainland China, Hong Kong, Macau and Taiwan).

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  from  transient  CDK4/6  inhibition  may  protect  bone  marrow  and  the
immune  system  from  cytotoxic  damage  during  treatment.  Transient  CDK4/6  inhibition  also  may  improve  survival  in  combination  with  leading  and
emerging  treatments  by  improving  long-term  immune  surveillance.  This  can  be  accomplished  through  protection  of  the  immune  system  for  improved
longer-term  function  and  by  potentially  increasing  the  generation  of  memory  T  cells,  which  may  provide  additional  benefit  after  treatment.  We  are
exploring  the  use  of  trilaciclib  in  clinical  trials  to  optimize  these  potential  benefits  in  combination  with  leading  and  emerging  treatments  for  patients.
Beyond  our  initial  extensive-stage  small  cell  lung  cancer  ("ES-SCLC")  indication  in  the  United  States,  we  plan  to  focus  our  efforts  on  two  core
development paths for trilaciclib in order to optimize the opportunity ahead, including: (1) triple negative breast cancer ("TNBC"), where trilaciclib has
demonstrated potential benefits across treatment settings in multiple Phase 2 studies, and (2) in antibody-drug conjugate ("ADC") combinations, in TNBC
and potentially other additional tumor types.

We believe we have opportunities for significant growth, including (1) optimizing COSELA in our initial ES-SCLC marketed indication in the U.S., (2)
commercializing this potentially transformational new treatment option for patients with metastatic TNBC, provided positive Phase 3 results and regulatory
approval, (3) advancing development in combination with leading ADC treatments with an opportunity to meaningfully improve their efficacy and safety,
and (4) pursuing global expansion through ongoing partnering initiatives.

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

Our Business Strategy

We  aspire  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 as the standard of care for ES-SCLC in the United States.
Maximize  long-term  value  of  trilaciclib  by  executing  our  development  plan  across  TNBC  treatment  settings  and  in  ADC
Combinations.
Manage capital efficiently to fully fund operations.

We believe that, because of the trilaciclib 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 and
to  meaningfully  improve  anti-tumor  efficacy  across  various  TNBC  treatment  settings  and  in  ADC  combinations.  Furthermore,  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.

Commercial Product

On  February  12,  2021,  FDA  approved  COSELA  (trilaciclib  for  intravenous  injection)  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. COSELA became
commercially available in the United States through our specialty distributor network on March 2, 2021.

COSELA  is  also  commercially  available  in  Greater  China  (i.e.,  mainland  China,  Hong  Kong,  Macau  and  Taiwan)  pursuant  to  an  exclusive  license
agreement  with  Simcere  in  August  2020  to  develop  and  commercialize  trilaciclib  for  any  indication  in  humans  through  parenteral  delivery,  including
intravenous  delivery,  in  China,  Hong  Kong,  Macau,  and  Taiwan.  See  "Business  -  License  Agreements  -  Exclusive  license  to  Simcere  for  trilaciclib  in
Greater China" section of this Annual Report for more details. COSELA (trilaciclib hydrochloride for injection) is indicated in Greater China to decrease
the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen for ES-
SCLC.

Product Portfolio

Our product portfolio consists of three assets: trilaciclib and lerociclib, both of which are CDK4/6 inhibitors, and a CDK2 inhibitor.

Trilaciclib

As a condition of marketing approval in ES-SCLC, we are required to conduct a post marketing trial of trilaciclib in combination with chemotherapy in
patients with ES-SCLC to evaluate survival outcomes. To meet this requirement, a trial of trilaciclib or placebo in combination with topotecan in patients
with ES-SCLC has been initiated and the first patient was enrolled in October 2023.

Beyond  our  continued  development  and  commercialization  of  our  initial  ES-SCLC  indication  in  the  U.S.,  we  are  focusing  our  efforts  on  two  core
development paths for trilaciclib, including (1) TNBC, where trilaciclib has demonstrated potential benefits across treatment settings in multiple Phase 2
studies, and (2) ADC combinations, in TNBC and potentially other additional tumor types.

Trilaciclib  is  a  novel  therapy  designed  to  transiently  arrest  cells  that  are  dependent  on  CDK4/6  for  proliferation,  including  hematopoietic  stem  and
progenitor cells ("HSPCs"), in the G1 phase. The unique product attributes of trilaciclib include: (1) rapid onset from IV administration, (2) potent and
selective  CDK4  and  CDK6  inhibition,  and  (3)  a  short  half-life.  These  attributes  enable  a  controlled  administration  of  trilaciclib  intended  to  achieve  a
precisely timed effect, a robust clean G1-phase arrest, and an optimal environment for T-cells to proliferate.

Trilaciclib has demonstrated an ability to protect the bone marrow and immune system from damage during cytotoxic treatment. This may lead to reduced
hematologic  adverse  events  ("AEs"),  which  can  mitigate  the  need  for  rescue  interventions  and  hospitalizations  and  potentially  increase  the  ability  of
patients to receive longer durations of treatment. Trilaciclib may also improve survival in combination with leading and emerging treatments through its
potential to improve long term immune surveillance in patients following treatment. This may occur through protection of immune system function, as well
as the potential for trilaciclib to increase the generation of memory T cells. These potential effects may provide additional longer-term benefit for cancer
patients after initial trilaciclib treatment.

Market opportunities for trilaciclib

Cancer is the second leading cause of death in the United States with an estimated 2.0 million new cases and 611,000 deaths expected to occur in 2024,
according to the American Cancer Society. Cytotoxic therapies (chemotherapies, antibody-drug conjugates, others) are the standard of care treatment for
many of these cancers.

Cytotoxic therapies 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  potentially  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.  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.

5

 
 
Additionally,  significant  unmet  medical  need  continues  to  exist  for  products  that  can  meaningfully  improve  the  anti-tumor  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 in Phase 2 and Phase 3 clinical trials to evaluate its
potential to improve anti-tumor efficacy and reduce adverse events that are commonly associated with cytotoxic therapies:

•

•

Extensive-stage  small  cell  lung  cancer  (ES-SCLC).  According  to  the  American  Cancer  Society,  small  cell  lung  cancer  ("SCLC")
accounts for approximately 10-15% of all lung cancers. Approximately 27,000 people are treated annually in the United States for
ES-SCLC  in  first  and  second  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 treatment regimen. We believe the total addressable market of the
trilaciclib opportunity for all eligible ES-SCLC patients in the U.S. exceeds $700 million.
Breast cancer. We are evaluating the use of trilaciclib in a variety of TNBC treatment settings, including metastatic and early stage
TNBC.  According  to  the  World  Health  Organization,  an  estimated  2.3  million  cases  of  breast  cancer  are  diagnosed  annually
worldwide. In 2023, it is estimated that 43,700 women and 530 men died of breast cancer. TNBC makes up approximately 15-20%
of  such  diagnosed  breast  cancers.  Because  TNBC  cells  lack  key  growth-signaling  receptors,  patients  do  not  respond  well  to
medications  that  block  estrogen,  progesterone,  or  HER2  receptors.  Instead,  treating  TNBC  typically  involves  cytotoxic  therapy,
radiation, and surgery. In general, survival rates tend to be lower with TNBC compared to other forms of breast cancer, and TNBC is
also more likely to return after it has been treated, especially in the first few years after treatment. We believe the total addressable
market in metastatic TNBC exceeds $1 billion in the U.S.

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 the potential to enable maintenance of the indicated and planned chemotherapeutic dose and schedule.
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,  and  improve  their  long-term  immune
surveillance.

6

•

•

•

•

•

Potential  for  use  with cytotoxic  therapy  /  antibody-drug  conjugate  combinations.  ADCs  including  TROP2  ADCs  are  among  the
fastest growing class of anti-cancer therapy. We have demonstrated that trilaciclib can be combined with ADCs to provide significant
reductions in on-target adverse events compared to historical ADC monotherapy data, and may improve overall survival compared to
that of ADCs alone.
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  potential  synergistic  benefits  in  terms  of  anti-tumor  efficacy  when  combining  trilaciclib  with  checkpoint  inhibitors  in  the
appropriate treatment settings.
Potential to reduce the cost of rescue interventions. Chemotherapy-induced myelosuppression leads to severe adverse side effects,
which often require costly rescue interventions such as hospitalizations, transfusions, antibiotic usage and/or treatment with growth
factor support. Because trilaciclib is expected to reduce myelosuppression, we believe it has the potential to reduce these costs. The
positive  proactive  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 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.
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.

Preclinical and Clinical Development for trilaciclib

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.

Phase 1 clinical trial in healthy volunteers

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 ("DLTs"), serious adverse events ("SAEs"), AEs, and pharmacokinetics ("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  for the initial
studies in patients.

Phase 2 clinical trial in ES-SCLC (study 1 in package insert)

Based  on  the  encouraging  preliminary  data,  we  advanced  both  ES-SCLC  trials  into  the  randomized,  placebo-controlled,  double-blind  Phase  2  segment.
Enrollment in the first-line ES-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 ESMO 2018 Congress and published in Annals of Oncology (Weiss et al.) in 2019. Enrollment
in the second/third-line ES-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 ASCO 2019 Annual Meeting. These data were also published in the International
Journal of Cancer (Daniel et al.; 2020).

We evaluated the combination of Genentech's immune checkpoint, anti-PD-L1 antibody Tecentriq with trilaciclib 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 were 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 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 ES-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 were 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  ASCO  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/m   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 ES-SCLC (study 3 in package insert)

In 2015, we initiated a Phase 1b/2 clinical trial in second/third-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 of the trial. The goals of
the  trial  were  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/m  and topotecan doses of 0.75 to 1.5 mg/m  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/m   +
2
topotecan 0.75 mg/m and trilaciclib 240 mg/m  + topotecan 1.5 mg/m .

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  ES-SCLC  trials  demonstrated  that,  when  added  to  standard  of  care  chemotherapy  or
chemotherapy/checkpoint  inhibitor  regimens,  trilaciclib  mitigates  clinically  significant  chemotherapy-induced  myelosuppression.  The  FDA  granted
Breakthrough Therapy Designation for trilaciclib based on myeloprotection data from our three randomized, double-blind, placebo-controlled ES-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  ES-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 ES-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 PFS. We presented additional safety and
anti-tumor efficacy data at the 2019 ESMO Congress. The results of the trial demonstrated significant improvement in 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 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.

Phase 3 clinical trial in metastatic colorectal cancer (PRESERVE 1) - Trial discontinued

PRESERVE 1 was 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  in  5-FU-based  regimens  with  trilaciclib.
PRESERVE 1 evaluated trilaciclib administered in combination with the triplet therapy FOLFOXIRI (5-FU, folinic acid, oxaliplatin and irinotecan) and
bevacizumab,  which  is  the  most  efficacious  chemotherapy  regimen  for  most  1L  CRC  tumors  but  also  highly  myelosuppressive  compared  to  doublet
therapies including FOLFOX or FOLFIRI.

On February 13, 2023 , we announced topline results from our pivotal Phase 3 PRESERVE 1 trial showing that the trial achieved its co-primary endpoints
related  to  severe  neutropenia  with  statistical  significance,  including  clinically  meaningful  and  statistically  significant  reductions  in  both  occurrence  of
severe  neutropenia  during  induction  (placebo=20%  vs.  trilaciclib=1%;  p<0.001)  and  mean  duration  of  severe  neutropenia  in  Cycles  1  through  4
(placebo=1.3 days vs. trilaciclib=0.1 days; p<0.001).

However, despite the achievement of the co-primary endpoints and other secondary measures of myeloprotection and tolerability, early anti-tumor efficacy
data, including ORR, favored patients receiving placebo compared to trilaciclib (61% and 50% ORRs, respectively). Given the differential in these anti-
tumor  efficacy  metrics  and  the  low  likelihood  of  achieving  the  PFS  and  OS  endpoints,  we  made  the  decision  to  discontinue  PRESERVE  1.  The  Data
Monitoring Committee (DMC) independently reached the same conclusion.

Other  clinical  trials  of  trilaciclib  in  combination  with  different  chemotherapies  in  patients  with  ES-SCLC  and  triple  negative  breast  cancer  did  not
demonstrate this adverse survival signal.

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

In November 2023, we announced the completion of the Phase 2 trial of trilaciclib in bladder cancer (PRESERVE 3). We concluded the trial following the
final fourth quarter protocol defined analyses of survival and plan to report the results at a future medical meeting. PRESERVE 3 was a signal finding study
designed to assess the potential additive contribution of trilaciclib to anti-cancer therapy, including in combination with the immune checkpoint inhibitor
avelumab alone without chemotherapy during the maintenance part of the study. An overall survival trend in favor of the trilaciclib plus avelumab arm in
the maintenance phase was observed, suggesting a potential additive benefit when used in combination with a checkpoint inhibitor. This Phase 2 trial has
been concluded and the information may inform future studies in our core areas of focus.

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

In June 2023, we presented final results during the 2023 ASCO meeting from 24 patients enrolled in our Phase 2, single arm mechanism of action study of
trilaciclib administered as a single agent to patients with early-stage TNBC prior to receiving trilaciclib and neoadjuvant therapy confirming that trilaciclib
can increase the pool of memory T cells in the tumor microenvironment responsible for long term immune surveillance and efficacy. These results highlight
the  potential  for  trilaciclib  to  enhance  long  term  immune  surveillance  by  increasing  T  cell  function  and  generation  of  certain  memory  T  cells  and
demonstrate gene expression profiles that may be associated with improved clinical outcome. These data support earlier findings from this Phase 2 trial
demonstrating an increase in the ratio of CD8+ T cells to regulatory T cells (Tregs); a high ratio of CD8+ T cell to Tregs is predictive of overall survival
(OS) and is associated with pathologic complete response (pCR). As expected, high rates of pCR were observed in patients with PD-L1(+) tumors and in
patients with inflamed tumor immune microenvironments.

Trilaciclib was shown to enhance the number and function of CD8+ T cells in the tumor microenvironment. Seven days after monotherapy with trilaciclib,
the  number  of  CD8+  T  cells  and  GZMB+  cells,  which  is  a  surrogate  marker  for  T  cell  function,  were  enhanced  with  statistical  significance  in  patients
achieving a pCR. There was also an increase in stromal TILs within the tumor microenvironment after a single dose of trilaciclib.

Ongoing clinical trials for trilaciclib

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

Building  upon  the  robust  OS  benefit  observed  in  the  prior  Phase  2  study,  we  initiated  PRESERVE  2,  a  pivotal  Phase  3  trial  of  trilaciclib  in  patients
receiving  first-line  GC  for  locally  advanced  unresectable  or  mTNBC.  Enrollment  was  completed  in  this  trial  in  October  2022.  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. We broadened 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. This trial is being conducted across multiple sites in the United States and Europe. We enrolled patients
who  previously  received  checkpoint  inhibitors  in  the  new/adjuvant  setting  into  the  trial,  to  ensure  that  we  develop  clinical  experience  in  this  patient
population. 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.  Enrollment  in  this  trial  is
complete at 187 IL patients.

An interim OS analysis at approximately 80% of events required for the final analysis was conducted in February 2024. The Independent Data Monitoring
Committee  ("DMC")  determined  that  the  trial  did  not  achieve  the  early  stopping  criteria  and  recommended  continuation  of  PRESERVE  2  to  the  final
analysis. The DMC raised no safety concerns nor did it recommend any other changes to the study. The final analysis will be conducted on the intent-to-
treat (ITT) population and is estimated to occur in the third quarter of 2024. G1 remains blinded to all data.

We  believe  that  the  additional  events  required  for  the  final  analysis  and  the  longer  follow  up  could  potentially  allow  patients  to  benefit  from  receiving
subsequent anticancer therapies following discontinuation of trilaciclib. This is based on new data we presented at the 2023 San Antonio Breast Cancer
Symposium  ("SABCS")  from  patients  with  mTNBC  who  participated  in  our  Phase  2  trial  (NCT02978716)  indicating  that  patients  with  mTNBC  who
received  trilaciclib  with  their  cytotoxic  chemotherapy  during  the  trial  and  then  received  subsequent  anticancer  therapy  ("SACT")  after  trilaciclib
discontinuation exhibit statistically significant and clinically meaningful improvements in median overall survival (OS) (32.7 months versus 12.8 months;
p=0.001).  Additionally,  median  OS  for  patients  who  received  prior  trilaciclib  was  improved  from  the  time  they  started  their  first  SACT  compared  to
patients who did not receive prior trilaciclib (14.0 months versus 5.8 months; p=0.001). Administering trilaciclib with cytotoxic chemotherapy also led to
improved survival in patients unable to receive SACT.

Phase 2 clinical trial in combination with the antibody-drug conjugate ("ADC"), Sacituzumab Govitecan ("SG")

In  TNBC,  trilaciclib,  in  combination  with  gemcitabine  and  carboplatin,  and  the  ADC,  SG,  have  both  shown  clinically  meaningful  and  substantial
improvements  in  overall  survival.  We  believe  that  trilaciclib  could  act  synergistically  with  ADCs  to  improve  overall  patient  outcomes  with  fewer
myelosuppressive side effects.

In the fourth quarter of 2021, we initiated this ongoing Phase 2, single arm, open-label study of trilaciclib administered prior to the ADC, SG in patients
with  unresectable  locally  advanced  or  mTNBC  in  the  fourth  quarter  of  2021.  Anti-tumor  efficacy  and  myeloprotective  endpoints  are  being  assessed.
Objectives included of the myeloprotective effects of trilaciclib, and the anti-tumor efficacy of trilaciclib when administered prior to SG as measured by
OS, PFS, ORR, duration of objective response (DOR), and clinical benefit rate (CBR).

In May 2023, we presented results at the ESMO meeting confirming the potential benefit of trilaciclib in reducing adverse events related to the TROP2
ADC,  SG.  The  data  suggested  a  potential  for  trilaciclib  to  meaningfully  reduce  adverse  events  related  to  use  of  SG,  including  that  trilaciclib  was  well
tolerated when administered prior to SG. Safety results showed a clinically meaningful on-target effect of trilaciclib to reduce (>50%) the rates of multiple
adverse  events  compared  to  the  previously  published  sacituzumab  govitecan-hziy  single  agent  safety  profile  from  the  ASCENT  trial,  including
myelosuppression (neutropenia, anemia) and diarrhea due to the presence of CDK4/6-expressing cells in the intestinal crypt.

In January 2024, we provided initial efficacy results from the ongoing Phase 2 ADC trial suggesting improved OS among patients receiving trilaciclib in
combination  with  SG.  Preliminary  data  from  the  ongoing  Phase  2  trial  of  trilaciclib  in  combination  with  SG  in  metastatic  TNBC  patients  suggested
clinically meaningful improvements in OS among patients receiving trilaciclib in combination with SG compared to SG alone based on historical data from
the ASCENT trial, including (1) current median OS of 17.9 months with trilaciclib vs 12.1 months for SG alone and (2) estimated 12-month survival of
59% of patients receiving trilaciclib in combination with SG, representing a ~20% improvement over SG alone. The clinical benefit rate was similar in both
arms: 47% (trilaciclib) vs 45% (SG; historical from ASCENT).

We expect to provide updated OS data from this study in mid-2024.

Post-marketing trial of trilaciclib in 2L ES-SCLC in combination with topotecan

We  are  conducting  an  approximately  300  patient  post-marketing  trial  of  trilaciclib  in  2L  ES-SCLC  in  combination  with  topotecan  (a  topoisomerase  1
inhibitor chemotherapy). This is a global study, which is intended to formally evaluate the OS for trilaciclib in combination with topotecan in this 2L ES-
SCLC patient population.

Phase 2 Investigator Sponsored Studies ("ISS") of trilaciclib

An ISS is a study that is proposed, developed, and conducted by a qualified sponsor external to G1 Therapeutics who assumes full responsibility for the
conduct of the study

G1  is  supporting  an  ISS  of  trilaciclib  and  lurbinectedin  in  patients  with  2L  ES-SCLC,  sponsored  by  UNC  Lineberger.  This  is  a  prospective,  non-
randomized,  single-arm  Phase  2  study  to  evaluate  trilaciclib  administered  intravenously  prior  to  lurbinectedin  in  approximately  30  participants  with
platinum  refractory  ES-SCLC  evaluating  myeloprotection,  and  efficacy  measures  (OS,  PFS,  and  ORR),  and  quality  of  life  assessments.  The  primary
endpoint is the rate of grade 4 neutropenia in any cycle. Secondary endpoints include mean duration (days) of grade 4 neutropenia in cycle 1, OS, PFS,
ORR, quality of life assessments, and the use of secondary/reactive supportive measures including G-CSF administration.

12

G1 is supporting an ISS of trilaciclib in combination with gemcitabine/carboplatin and pembrolizumab, which is being sponsored by Atrium Health Levine
Cancer  Institute.  This  is  an  open  label,  single-arm,  phase  2  study  to  evaluate  trilaciclib,  pembrolizumab,  gemcitabine  and  carboplatin  administered  to
approximately 36 participants with locally advanced unresectable or metastatic TNBC evaluating efficacy, safety and tolerability measures.

Regulatory Status for trilaciclib

The FDA approved COSELA for injection 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  ES-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  and  the  New  Drug  Application  (NDA)  received  priority  review.  As  a  condition  of  approval,  we  were  required  to
complete certain post-marketing activities. The only remaining post-marketing activity is completion of 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 have completed site selection for the post-approval clinical trial, site activations are in
progress, and the first patient was enrolled in October 2023.

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 an 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 additional
tumor types and treatment combinations, including breast cancer.

Lerociclib

Lerociclib is a differentiated clinical-stage oral CDK4/6 inhibitor being developed for use in combination with other targeted therapies in multiple oncology
indications.  We  are  not  actively  pursuing  preclinical  or  clinical  development  activities  for  lerociclib.  In  2020,  we  out-licensed  the  development  and
commercialization  of  lerociclib  in  all  indications.  See  "Business  -  License  Agreements  -  Exclusive  License  to  Genor  for  lerociclib  in  certain  licensed
territories" section of this Annual Report for more details.

CDK2 Inhibitor

Cyclin-dependent kinase 2 ("CDK2") is an internally discovered inhibitor. We are not actively pursuing preclinical or clinical development activities for
CDK2. In 2020, we out-licensed the development and commercialization of CDK2 inhibitor for all human and veterinary uses. See "Business - License
Agreements - Exclusive License to Incyclix" section of this Annual Report for more details.

Commercialization

In February 2021, the 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  ES-SCLC.  Our  commercial  team  includes  sales,
marketing,  market  access,  strategic  accounts  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.

COSELA  is  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. Furthermore,
COSELA is recommended as a myeloid supportive agent in the updated American Society of Clinical Oncology (“ASCO”) SCLC guidelines for patients
with  untreated  or  previously  treated  ES-SCLC  who  are  undergoing  treatment  with  chemotherapy  or  chemoimmunotherapy.  These  guidelines  provide
evidence-based,  consensus-driven  recommendations  to  practicing  clinicians  to  ensure  that  all  patients  receive  preventive,  diagnostic,  treatment,  and
supportive services that are most likely to lead to optimal outcomes. The Centers for Medicare & Medicaid Services ("CMS") issued the permanent J-code
for  COSELA,  allowing  providers  to  bill  for  it  at  all  sites  of  care.  This  standardized  the  submission  and  payment  of  COSELA  insurance  claims  across
Medicare, Medicare Advantage, Medicaid, and commercial plans for all hospital outpatient departments, ambulatory surgery centers, and physician offices
in the United States using the Healthcare Common Procedure Coding System ("HCPCS") code.

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  ("CMOs")  for  the  manufacture  of  our  product  candidates.  To  date,  we  have  obtained  drug  substances  and  drug
product  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 product. As development proceeds for our products, we will evaluate qualifying additional redundant manufacturers
for drug substances and drug product.

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.

Intellectual property

Our  commercial  success  depends  in  part  on  our  ability  to  obtain,  maintain,  and  enforce  proprietary  protection  in  jurisdictions  where  we  seek  to
commercialize our FDA approved CDK4/6 inhibitor trilaciclib (COSELA) and where our licensees seek to commercialize our proprietary CDK inhibitors,
including  trilaciclib  and  clinical  candidate  lerociclib.  We  also,  where  we  believe  appropriate,  seek  protection  on  processes  for  the  production  of  our
CDK4/6  inhibitors,  formulations,  additional  compositions,  combinations  of  our  product  candidates  with  other  active  agents  and  dosing  schedules  and
regimens. In addition, we plan to seek patent term adjustments, restorations, and/or patent term extensions where applicable in the United States and other
jurisdictions. 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  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. 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  product.  See  "Business  -  Government
Regulation and Product Approval” section of this Annual Report for more details.

Our owned and in-licensed patent estate as of December 31, 2023, on a worldwide basis, includes over 385 granted or pending patent applications in more
than 26 patent families with more than 55 granted U.S. patents. Our intellectual property strategy includes patenting our CDK4/6 inhibitors, their uses, and
methods of manufacturing. 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 eighteen 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.

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.

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 have filed for patent term extensions with
the United States Patent and Trademark Office seeking the extension of term for patents encompassing trilaciclib.

Our current issued patents covering methods of use of trilaciclib will expire in 2034 to 2039. Our pending applications on additional methods of use of
trilaciclib, 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.

In addition, we own four issued U.S. Patents (U.S. 9,487,530; U.S. 10,085,992; U.S. 10,966,984; and U.S. 11,717,523) covering the use of trilaciclib to
reduce  the  effect  of  chemotherapy  on  healthy  cells  in  a  subject  being  treated  for  cancer  or  to  treat  a  subject  with  cancer  in  combination  with  a
chemotherapeutic agent, each of which has been listed in the Orange Book listing for COSELA. This patent family covers, for example, SCLC treatment
protocols involving chemotherapeutic agents carboplatin, etoposide, and/or topotecan along with trilaciclib for protection of healthy replicating cells like
hematopoietic  stem  and  progenitor  cells,  and  the  use  of  trilaciclib  to  treat  cancer,  including  SCLC,  in  combination  with  a  chemotherapeutic  agent.  The
patent filing also covers chemoprotection of healthy replicating cells with trilaciclib during the treatment of CDK4/6 independent cancer including triple
negative  breast  cancer,  and  the  use  of  trilaciclib  to  treat  TNBC  in  combination  with  a  chemotherapeutic  agent.  Patents  from  this  family  have  issued  in
Europe,  China,  Hong  Kong,  Macau,  Canada,  and  Japan.  Patent  applications  from  this  family  are  pending  in  Europe,  Japan,  and  the  United  States.  The
expected  year  of  expiration  for  this  patent  family,  where  issued,  valid  and  enforceable,  is  2034,  without  regard  to  any  extensions,  adjustments,  or
restorations of term that may be available under national law. 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,  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 and elected (as described further below), would extend the term of this patent to February 12, 2035. We
ultimately intend to elect one patent (U.S. 8,598,186 or U.S. 9,487,530) for extension under 35 U.S.C. § 156.

We have filed applications in the United States, in the European Patent Office (EPO), Canada, China, Hong Kong, Australia, Brazil, Israel, Japan, South

License Agreements

We  are  the  sole  owner  or  exclusive  licensee  of  all  of  our  patents  and  currently  filed  patent  applications  that  cover  the  composition  of  trilaciclib  and
lerociclib,  the  manufacture  of  trilaciclib  and  lerociclib,  and  our  use  or  our  licensees'  use  of  trilaciclib  and  lerociclib.  We  have  the  exclusive  right  to
prosecute  all  pending  patent  families  related  to  trilaciclib  and  lerociclib  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 review and comments will be considered by us in
good faith. In 2023, we were party to four out-licensing agreements concerning our CDK inhibitor technology with each of Simcere, Genor, and Incyclix;
however, our fourth out-license agreement with EQRx was terminated in the third quarter of 2023.

Exclusive license to Simcere for trilaciclib in Greater China

On August 3, 2020, we entered into an exclusive license agreement with 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, we 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. Since entering into the license agreement, we have received an upfront payment of $14.0 million and an
additional $22.0 million for the achievement of development milestones.

On  April  28,  2023,  we  amended  the  license  agreement  with  Simcere,  whereby  we  received  a  one-time,  non-refundable  payment  of  $30.0  million  in
exchange  for  the  relief  of  future  royalty  payments  from  the  sale  of  COSELA  in  Greater  China.  In  addition,  the  milestone  payments  under  the  license
agreement were adjusted such that we will be eligible to receive a $5.0 million payment upon Simcere’s filing an NDA of TNBC in mainland China and a
$13.0 million payment upon Simcere receiving regulatory approval of TNBC in mainland China. Under the amended license agreement, Simcere is not
responsible for any sales milestone payments or any royalties accrued after April 28, 2023. Following the amendment, we continue to own all the global
development and commercial rights to trilaciclib, excluding Greater China.

During the twelve months ended December 31, 2023, we recognized $30.0 million in revenue from the one-time payment for the relief of future royalty
payments, $2.9 million in supply and manufacturing services, $0.6 million in royalty revenue, and $0.7 million in patent and clinical trial reimbursable
costs.

Exclusive license to Genor Biopharma Co. Inc. ("Genor") for lerociclib in certain licensed territories

On June 15, 2020, we entered into a license agreement with Genor for the development and commercialization of lerociclib using an oral dosage form to
treat any indication in humans (the “Genor License”). The Genor licensed territories are in Australia, Bangladesh, China, Hong Kong, India, Indonesia,
Macau,  Malaysia,  Myanmar,  New  Zealand,  Pakistan,  Philippines,  Singapore,  South  Korea,  Sri  Lanka,  Taiwan,  Thailand,  and  Vietnam  (the  “Genor
Territory”).  Pursuant  to  the  Genor  License,  Genor  has  been  granted  an  exclusive,  royalty-bearing,  non-transferable  license,  with  the  right  to  grant
sublicenses,  to  ten  of  our  solely-owned  patent  families  in  the  Genor  Territory.  We  maintain  the  exclusive  right  to  prosecute  these  patent  families  in  the
Genor Territory, and Genor has the right to review and comment on all material patent filings, such review and comment to be considered by us in good
faith.

Under the Genor License, Genor shares all patent prosecution costs incurred in the Genor Territory with us. We are solely responsible for costs associated
with any adversarial patent prosecution proceeding in the Genor Territory, including oppositions, reexaminations, invalidations, revocations, nullifications,
or cancellation proceedings related to our licensed patent families.

18

Under the Genor License, we have the sole right in our discretion to bring and control any legal action to enforce our licensed patent families against any
infringement action in the Genor Territory, except in the case of i) a G1 patent containing a claim to the composition-of-matter of lerociclib or ii) a G1
patent that contains claims covering only lerociclib that arises as a result of making, using, offering to sell, selling or importing of lerociclib by a third
party,  in  which  case  we  have  the  first  right,  but  not  the  obligation,  to  bring  and  control  any  infringement  action  at  our  own  expense,  subject  to  the
consideration  of  Genor’s  reasonable  and  timely  comments.  To  the  extent  we  decline  to  bring  an  action  against  an  infringer  under  the  above-described
conditions, Genor has the right, but not the obligation, to bring an infringement action at its own expense.

Pursuant to the license agreement, Genor agreed to pay us 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 us tiered royalties ranging from high single to
low double-digits based on annual net sales of lerociclib in the Genor Territory. The upfront cash payment was received in July 2020. In September 2020,
we 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.  Genor  will  be  responsible  for  the  development  of  the  product  in  the  Genor  Territory  and  will  be  responsible,  at  its  sole  cost,  for
obtaining supply of lerociclib to meet its development, regulatory approval, and commercialization obligations under the agreement. Since entering into the
license  agreement,  we  have  received  an  upfront  payment  of  $6.0  million  and  an  additional  $3.0  million  for  the  achievement  of  development  and
commercial milestones. During the twelve months ended December 31, 2023, we did not recognize any revenue related to development milestones.

Exclusive license to Incyclix

On May 22, 2020, we entered into a global license agreement with Incyclix, formerly ARC Therapeutics, LLC, for the development and commercialization
of a CDK2 inhibitor for all human and veterinary uses. Pursuant to the Incyclix License, Incyclix is currently granted an exclusive, royalty-bearing, license
with the right to grant sublicenses to one of our solely-owned patent families. At close, we received consideration in the form of an upfront payment of
$1.0 million and an equity interest in Incyclix equal to 10% of its issued and outstanding units valued at $1.1 million. In addition, we 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. In the first quarter of 2022, Incyclix announced a new round of financing which we did not participate. Following the financing, our
equity interest is now approximately 6.5%.

We also have right of first negotiation to re-acquire these assets. In 2021, Incyclix returned three of the four licensed patent families. Under the Incyclix
License, Incyclix received the exclusive right to prosecute these patent families in its sole discretion, and we have the right to review and comment on all
material patent filings, and our review and comments will be considered by Incyclix in good faith.

Under the Incyclix License, Incyclix is solely responsible for all patent prosecution costs. Incyclix has the first right, but not the obligation, to bring and
control any infringement action at its own expense, subject to Incyclix keeping us reasonably informed. Incyclix also has the right to name and join us in
any infringement action relating to our patents. In the case of a patent certification in connection with an Abbreviated New Drug Application under the U.S.
Hatch Waxman Act, or the substantial equivalent in a foreign country, if Incyclix declines to file a lawsuit, we have the right to bring an infringement action
at our own expense. There was no revenue recognized during twelve months ended December 31, 2023.

Exclusive license to EQRx for lerociclib - terminated

On July 22, 2020, we 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, we 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.

19

Under  the  license  agreement,  EQRx  agreed  to  pay  us  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 would pay us tiered royalties ranging from mid-single
digits to mid-teens based on annual net sales of lerociclib in the EQRx Territory. In September 2020, we transferred to EQRx the related technology and
know-how that was necessary to develop, seek regulatory approval for, and commercialize lerociclib in the EQRx Territory. EQRx was responsible for the
development of the product in the EQRx Territory. We agreed to continue until completion, as the clinical trial sponsor, our two primary clinical trials and
EQRx agreed to reimburse us for all related out-of-pocket costs incurred after the effective date of the license agreement.

On August 1, 2023, we received from EQRx formal notice of termination of the lerociclib license agreement in connection with the acquisition of EQRx by
Revolution Medicines, Inc. The notice stated the intention to revert the lerociclib product rights back to us. Under the terms of the license agreement, EQRx
was responsible for winding down its development activities. On September 13, 2023, the parties entered into a letter agreement whereby EQRx would pay
us  $1.6  million  to  reimburse  anticipated  wind  down  costs;  the  payment  was  received  during  the  third  quarter  of  2023.  No  milestones  were  previously
achieved through the date of termination of the lerociclib license agreement, and as a result of the termination, we will not receive any further milestone
payments or future royalties from EQRx.

During  the  twelve  months  ended  December  31,  2023,  we  recognized  revenue  of  $1.7  million  for  the  reimbursement  of  patent  and  clinical  trial  costs,
including $1.4 million of the $1.6 million payment received during the third quarter of 2023 following notice from EQRx of termination of the license
agreement. As of December 31, 2023, the remaining $0.2 million is held as short-term deferred revenue on the balance sheet and will be recognized as
revenue as clinical trial costs associated with the wind down are incurred.

In light of the EQRx termination, we directed the abandonment of certain patents and patent applications solely directed to lerociclib, or its use, in certain
EQRx territories. No granted patents, however, have been abandoned in the United States.

Government Regulation and Product Approval

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,  the  government  has  brought  enforcement  actions  against
clinical trial sponsors that fail to comply with such requirements.

Pediatric clinical trials and exclusivity

Under  the  Pediatric  Research  Equity  Act  ("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 ("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.

20

The Best Pharmaceuticals for Children Act ("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.

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  (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 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  potential  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 ("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.

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 ("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.

Congress also recently amended the FDC Act to require sponsors of a Phase 3 clinical trial, or other “pivotal study” of a new drug to support marketing
authorization, to design and submit a diversity action plan for such clinical trial. The action plan must include the sponsor’s diversity goals for enrollment,
as well as a rationale for the goals and a description of how the sponsor will meet them. Sponsors must submit a diversity action plan to the FDA by the
time the sponsor submits the relevant clinical trial protocol to the agency for review. The FDA may grant a waiver for some or all of the requirements for a
diversity action plan. It is unknown at this time how the diversity action plan may affect Phase 3 trial planning and timing or what specific information
FDA will expect in such plans, but if the FDA objects to a sponsor’s diversity action plan or otherwise requires significant changes to be made, it could
delay initiation of the relevant clinical trial.

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, before the trial commences. An IRB also monitors the trial on an ongoing basis consistent with regulatory requirements
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.

21

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, as well as proposed labeling and information about the product's manufacturing facility or
facilities.  The  cost  of  preparing  and  submitting  an  NDA  is  substantial.  Under  federal  law,  the  submission  of  most  NDAs  is  subject  to  a  substantial
application user fee and an annual program fee for approved NDAs. In 2024 the fee for an NDA submission with clinical information is over $4 million
and  the  annual  program  fee  for  an  approved  NDA  is  over  $416  thousand.  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  ("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 ("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 healthcare professionals, medication guides for patients,
and/or elements to assure safe use ("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  post
marketing commitments or requirements included in the approval letter. Once granted, product approvals may be withdrawn if compliance with regulatory
requirements and commitments is not maintained or problems are identified following initial marketing.

22

Fast track, breakthrough therapy, RTOR, 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  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.

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.

Specific to oncology drug applications, FDA’s Oncology Center of Excellence has developed a program called Real-Time Oncology Review (“RTOR”).
RTOR  facilitates  earlier  submission  of  topline  results  (i.e.,  efficacy  and  safety  results  from  clinical  studies  before  the  study  report  is  completed)  and
datasets, after database lock, to support an earlier start to the agency’s review of a marketing application review. The intent of RTOR is to provide FDA
reviewers earlier access to data, to identify data quality and potential review issues, and to potentially enable early feedback to the applicant, which can
allow for a more streamlined and efficient review process for the product’s NDA. Applicants can apply for review under RTOR when the database for a
pivotal trial has been locked and the oncology product is eligible under FDA’s criteria for the program. Eligibility requires (a) clinical evidence indicating
that the drug may demonstrate substantial improvement on one or more clinically relevant endpoints over available therapies; (b) the use of straightforward
study designs and easily interpreted clinical trial endpoints (e.g., overall survival, response rates); and (c) that no aspect of the NDA is likely to require a
longer review time (e.g., requirement for new REMS or input from an advisory committee). In November 2023, the agency finalized guidance for industry
on RTOR.

Fast  track  designation,  breakthrough  therapy  designation,  RTOR,  and  priority  review  do  not  change  the  standards  for  approval  and  may  not  ultimately
expedite the development or approval process.

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 ("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.

23

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.

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. However, companies may share
truthful  and  not  misleading  information  that  is  not  inconsistent  with  the  product's  labeling,  and  the  FDA  has  recently  published  a  draft  guidance  with
recommendations  for  how  drug  manufacturers  can  share  scientifically  sound  and  clinically  relevant  information  on  unapproved  uses  with  health  care
providers  so  long  as  such  presentations  are  not  promotional.  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 healthcare programs; or
mandated modification of promotional materials and labeling and the issuance of corrective information.

24

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  inpatient  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.

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 (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. More recently, the Drug Supply Chain Security Act (the "DSCSA") was enacted with the aim of building an electronic system to identify and
trace  certain  prescription  drugs  distributed  in  the  United  States.  The  DSCSA  mandates  phased-in  and  resource-intensive  obligations  for  pharmaceutical
manufacturers,  wholesale  distributors,  and  dispensers  over  a  10‑year  period  that  culminated  in  November  2023.  However,  FDA  announced  a  one-year
stabilization period, until November 2024, to give entities subject to the DSCSA additional time to finalize interoperable tracking systems and to ensure
supply chain continuity. 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. For example, the FDA released proposed regulations in February
2022 to amend the national standards for licensing of wholesale drug distributors by the states; establish new minimum standards for state licensing third-
party logistics providers; and create a federal system for licensure for use in the absence of a state program, each of which is mandated by the DSCSA. 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.

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.

25

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.

Accordingly, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support
for the use of our FDA-approved products to each payor separately, with no assurance that coverage and adequate payment will be applied consistently or
granted  at  all.  The  process  for  determining  whether  a  payor  will  cover  and  how  much  it  will  reimburse  a  product  may  be  separate  from  the  process  of
seeking  approval  of  the  product  or  for  setting  the  price  of  the  product.  Even  if  reimbursement  is  provided,  market  acceptance  of  our  products  may  be
adversely affected if the amount of payment for our products proves to be unprofitable for healthcare providers or less profitable than alternative treatments
or if administrative burdens make our products less desirable to use.

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. For example, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring
more  transparency  to  drug  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reform  government  program
reimbursement  methodologies  for  drugs.  In  August  2022,  President  Biden  signed  into  the  law  the  Inflation  Reduction  Act  of  2022  (the  “IRA”),  which
includes (among other things) multiple provisions that may impact the prices of drug products that are both sold into the Medicare program and throughout
the  United  States.  A  manufacturer  of  drug  products  covered  by  Medicare  Parts  B  or  D  must  now  pay  a  rebate  to  the  federal  government  if  their  drug
product’s price increases faster than the rate of inflation. This calculation is made on a drug product by drug product basis and the amount of the rebate
owed to the federal government is directly dependent on the volume of a drug product that is paid for by Medicare Parts B or D. Additionally, starting for
payment year 2026, CMS will negotiate drug prices annually for a select number of single source Part D drugs without generic competition. CMS will also
negotiate  drug  prices  for  a  select  number  of  Part  B  drugs  starting  for  payment  year  2028.  If  a  drug  product  is  selected  by  CMS  for  negotiation,  it  is
expected  that  the  revenue  generated  from  such  drug  will  decrease.  CMS  has  begun  to  implement  these  new  authorities  and  entered  into  the  first  set  of
agreements with pharmaceutical manufacturers to conduct price negotiations in October 2023. However, the IRA’s impact on the pharmaceutical industry
in  the  United  States  remains  uncertain,  in  part  because  multiple  large  pharmaceutical  companies  and  other  stakeholders  (e.g.,  the  U.S.  Chamber  of
Commerce) have initiated federal lawsuits against CMS arguing the program is unconstitutional for a variety of reasons, among other complaints. Those
lawsuits are currently ongoing.

We  expect  that  federal,  state  and  local  governments  in  the  U.S.  will  continue  to  consider  legislation  directed  at  lowering  the  total  cost  of  healthcare.
Individual states in the United States have 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. For example, in recent years, several states
have  formed  prescription  drug  affordability  boards  (“PDABs”).  Much  like  the  IRA’s  drug  price  negotiation  program,  these  PDABs  have  attempted  to
implement  upper  payment  limits  on  drugs  sold  in  their  respective  states  in  both  public  and  commercial  health  plans.  As  an  example,  in  August  2023,
Colorado’s  PDAB  announced  a  list  of  five  prescription  drugs  that  would  undergo  an  affordability  review.  The  effects  of  these  efforts  remain  uncertain
pending the outcomes of several federal lawsuits challenging state authority to regulate prescription drug payment limits.

If 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 EU, 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) in order to obtain reimbursement or pricing approval. For example, the
EU 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. EU 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 healthcare 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  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 EU 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  EU  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 in the future, 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.  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. We contract with a third-party service provider to provide COSELA to
qualifying uninsured or underinsured patients within the population indicated in our label. Less than 3% of utilization has been through this patient support
program.

27

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,
paying, 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 a variety
of 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  ("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, among other things, requires manufacturers of FDA-approved drugs, devices, biologics and
medical supplies covered by Medicare, Medicaid, or the Children’s Health Insurance Program to report to CMS, on an annual basis,
information  related  to  payments  and  other  transfers  of  value  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,
podiatrists, chiropractors and certain advanced non-physician healthcare practitioners, and teaching hospitals, as well as ownership
and investment interests held by physicians and their immediate family members;
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act ("HITECH") and its 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;

28

•

•

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 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.

Ensuring that our current and future business arrangements with third parties comply with applicable privacy, consumer protection, and 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. Moreover, if any of
the  physicians  or  other  healthcare  providers  or  entities  with  whom  we  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 healthcare systems that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect
the  ability  to  profitably  sell  product  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 or affect our ability to successfully
commercialize  COSELA  for  its  approved  indication(s).  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.  See  additional  disclosures  above  under
"Pharmaceutical Coverage, Pricing, and Reimbursement."

For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the "ACA"),
was enacted in March 2010 and has had a significant impact on the healthcare 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,  the  Creating  and  Restoring  Equal  Access  to  Equivalent  Samples  Act  of  2019  (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 established
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 uncertain and its potential effects on future competition for COSELA or any of our
other future commercial products are unknown.

29

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 ("ASP") to Department of Health and Human Services ("DHHS") beginning on January 1, 2022, subject to enforcement via
civil money penalties. More recently, the American Rescue Plan Act of 2021 included a provision that eliminated the statutory cap on rebates that drug
manufacturers  pay  to  Medicaid.  Beginning  in  January  2024,  Medicaid  rebates  are  no  longer  being  capped  at  100  percent  of  the  quarterly  average
manufacturer price ("AMP").

As  noted  above  under  "Pharmaceutical  Coverage,  Pricing  and  Reimbursement,"  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  pharmacy  benefit  managers  ("PBMs")  and  other  members  of  the  health  care  and  pharmaceutical  supply  chain,  an  important
decision  that  has  led  to  more  aggressive  efforts  by  states  in  this  area.  The  Federal  Trade  Commission  (“FTC”)  in  mid-2022  also  launched  sweeping
investigations  into  the  practices  of  the  PBM  industry  that  could  lead  to  additional  federal  and  state  legislative  or  regulatory  proposals  targeting  such
entities’ operations, pharmacy networks, or financial arrangements. During the current congressional session, numerous PBM reforms are being considered
in both the Senate and the House of Representatives; they include diverse legislative proposals such as eliminating rebates; divorcing service fees from the
price  of  a  drug,  discount,  or  rebate;  prohibiting  spread  pricing;  limiting  administrative  fees;  requiring  PBMs  to  report  formulary  placement  rationale;
promoting transparency. Significant efforts to change the PBM industry as it currently exists in the U.S. may affect the entire pharmaceutical supply chain
and the business of other stakeholders, including pharmaceutical product developers like us.

Further, in September 2023, the FTC issued a policy statement articulating its view that certain “improper” patent listings by drug developers in FDA’s
Orange Book represent an unfair trade practice and indicated that industry should be prepared for potential enforcement actions based on its analysis. The
FTC followed that action in November 2023 by publicly calling out over 100 “improper” patent listings made by ten large pharmaceutical companies and
initiating an FDA administrative process with respect to those patents. It remains to be seen whether the FTC, other governmental agencies, pharmaceutical
manufacturers, or other stakeholders continue to prioritize the policy issue of “improper” patent listings and whether significant litigation will develop in
this  area.  Accordingly,  regulatory  and  government  interest  in  biopharmaceutical  industry  business  practices  continues  to  expand  and  pose  a  risk  of
uncertainty.

In  the  EU,  similar  political,  economic  and  regulatory  developments  may  affect  our  ability  to  profitably  commercialize  our  products.  In  addition  to
continuing  pressure  on  prices  and  cost  containment  measures,  legislative  developments  at  the  EU  or  EU  member  state  level  may  result  in  significant
additional requirements or obstacles that may increase our operating costs. For example, in April 2023 the European Commission issued a proposal that
will revise and replace the existing general pharmaceutical legislation. If adopted and implemented as currently proposed, these revisions will significantly
change several aspects of drug development and approval in the European Union.

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.

U.S. Foreign Corrupt Practices Act

In general, the Foreign Corrupt Practices Act of 1977, as amended, (the “FCPA”) prohibits offering to pay, paying, promising to pay, or authorizing the
payment of money or anything of value to a foreign official in order to influence any act or decision of the foreign official in his or her official capacity or
to secure any other improper advantage in order to obtain or retain business for or with, or in order to direct business to, any person. The prohibitions apply
not only to payments made to “any foreign official,” but also those made to “any foreign political party or official thereof,” to “any candidate for foreign
political office” or to any person, while knowing that all or a portion of the payment will be offered, given, or promised to anyone in any of the foregoing
categories. “Foreign officials” under the FCPA include officers or employees of a department, agency, or instrumentality of a foreign government. The term
“instrumentality” is broad and can include state-owned or state-controlled entities.

30

Importantly, United States authorities that enforce the FCPA, including the Department of Justice, deem most healthcare professionals and other employees
of foreign hospitals, clinics, research facilities and medical schools in countries with public health care or public education systems to be “foreign officials”
under  the  FCPA.  When  we,  or  any  of  our  agents,  interact  with  foreign  healthcare  professionals  and  researchers  in  testing  and  marketing  our  products
abroad, we must have policies and procedures in place sufficient to prevent us and agents acting on our behalf from providing any bribe, gift or gratuity,
including  excessive  or  lavish  meals,  travel  or  entertainment  in  connection  with  marketing  our  products  and  services  or  securing  required  permits  and
approvals  such  as  those  needed  to  initiate  clinical  trials  in  foreign  jurisdictions.  The  FCPA  also  obligates  companies  whose  securities  are  listed  in  the
United States to comply with accounting provisions requiring the maintenance of books and records that accurately and fairly reflect all transactions of the
corporation,  including  international  subsidiaries,  and  the  development  and  maintenance  of  an  adequate  system  of  internal  accounting  controls  for
international operations. The U.S. Securities and Exchange Commission is involved with the books and records provisions of the FCPA.

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  ("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.
In  addition,  European  clinical  trials  legislation  has  recently  been  reformed  with  the  aims  of  harmonizing  and  streamlining  clinical-trial  authorization,
simplifying adverse-event reporting procedures, improving the supervision of clinical trials and increasing their transparency. Specifically, the new Clinical
Trials  Regulation,  (EU)  No  536/2014  (Clinical  Trials  Regulation)  came  into  application  on  January  31,  2022  and  is  directly  applicable  in  all  the  EU
Member States, repealing the previous Clinical Trials Directive 2001/20/EC. The extent to which ongoing clinical trials are governed by the Clinical Trials
Regulation depends on when the Clinical Trials Regulation became applicable and on the duration of the individual clinical trial. If a clinical trial continues
for more than three years from the day on which the Clinical Trials Regulation became applicable the Clinical Trials Regulation will at that time begin to
apply to the clinical trial. In addition, use of the new EU-wide application procedure being implemented via the Clinical Trial Information System (“CTIS”)
became mandatory for new clinical trial application submissions as of February 1, 2023.

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.  In  April  2023  the
European  Commission  issued  a  proposal  that  will  revise  and  replace  the  existing  general  pharmaceutical  legislation.  If  adopted  and  implemented  as
currently proposed, these revisions will significantly change several aspects of drug development and approval in the EU.

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 ("MAA"). The way in which a medicinal product can be approved in the European Union depends on the nature of the medicinal product.

31

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 ("CHMP") with adoption of the actual marketing authorization by
the European Commission thereafter. Accelerated evaluation 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  ("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.

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, including but not limited to the Federal Trade Commission Act. 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. Although we are not directly subject to HIPAA, we could potentially be subject to criminal penalties
if we or our agents knowingly receive individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized
or permitted by HIPAA.

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.  In  addition,  the  California  Consumer  Privacy  Act  ("CCPA")  became  effective  in  January  of  2020.  The  CCPA,  as
amended  by  the  California  Privacy  Rights  Act  ("CPRA,"  and  together,  the  "CCPA")  which  came  into  full  effect  in  January  of  2023,  broadly  defines
personal information, and creates new privacy rights and protections for Californians, places increased privacy and security obligations on entities handling
personal  data,  and  adds  civil  penalties  for  violations  and  a  private  right  of  action  by  data  breaches.  The  CCPA  requires  covered  companies  to  provide
certain  disclosures  to  consumers  (including  employees  and  contractors)  about  its  data  collection,  use,  and  sharing  practices,  and  to  provide  affected
California  residents  with  ways  to  opt-out  of  certain  sales  or  transfers  of  personal  information.  The  CPRA  modifies  the  CCPA  significantly  including
establishing a new regulatory agency, the California Privacy Protection Agency, which is charged with enacting regulations and has expanded enforcement
authority. The scope of the new regulations and the effect on operations is still unclear, resulting in further uncertainty, additional costs and expenses in an
effort to comply and additional potential for harm and liability for failure to comply.

In  addition  to  the  CCPA,  new  comprehensive  privacy  and  security  laws  have  been  proposed  in  more  than  half  of  the  states  in  the  U.S.,  and  Congress
continues to propose federal privacy legislation. Colorado, Connecticut, Virginia, and Utah all had comprehensive privacy laws that took effect in 2023 and
other states have laws taking effect in 2024 and 2025. The effects of these multiple and differing state laws, and other similar state or federal laws, are
potentially significant and may require us to modify our data processing practices and policies and incur substantial costs and potential liability in an effort
to comply with such legislation.

Europe - Data Privacy

In Europe, our clinical trials may be subject to the General Data Protection Regulation ("GDPR") and the UK GDPR (collectively, the "GDPR") which
went into effect in May 2018 and which imposes obligations on companies that operate in our industry with respect to the processing of personal data and
the  cross-border  transfer  of  such  data.  The  GDPR  applies  to  any  company  established  in  the  European  Economic  Area  ("EEA")  (which  includes  the
European Union ("EU") member states plus Iceland, Liechtenstein, and Norway) and to companies established outside the EEA that process personal data
in connection with the offering of goods or services to data subjects in the EEA or the monitoring of the behavior of data subjects in the EEA. The GDPR
establishes  stringent  requirements  applicable  to  the  processing  of  personal  data,  including  strict  requirements  relating  to  the  validity  of  consent  of  data
subjects, expanded disclosures about how personal data is used, requirements to conduct data protection impact assessments for “high risk” processing,
limitations  on  retention  of  personal  data,  special  provisions  affording  greater  protection  to  and  requiring  additional  compliance  measures  for  “special
categories  of  personal  data”  including  health  and  genetic  information  of  data  subjects,  mandatory  data  breach  notification  (in  certain  circumstances),
“privacy by design” requirements, and direct obligations on service providers acting as processors. The GDPR also prohibits the international transfer of
personal  data  from  the  EEA  to  countries  outside  of  the  EEA  unless  made  to  a  country  deemed  to  have  adequate  data  privacy  laws  by  the  European
Commission  or  a  data  transfer  mechanism  has  been  put  in  place.  If  our  or  our  partners’  or  service  providers’  privacy  or  data  security  measures  fail  to
comply with the GDPR requirements, we may be subject to litigation, regulatory investigations, enforcement notices requiring us to change the way we use
personal data and/or fines of up to 20 million Euros or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher,
as well as compensation claims by affected individuals, negative publicity, reputational harm and a potential loss of business and goodwill. The GDPR may
also impose additional compliance obligations relating to the transfer of data between us and our affiliates, collaborators, or other business partners. For
example, on July 16, 2020, the Court of Justice of the European Union (CJEU), issued a landmark opinion in the case Maximilian Schrems vs. Facebook
(Case C-311/18), called Schrems II. This decision (a) calls into question commonly relied upon data transfer mechanisms as between the EU member states
and the United States (such as the Standard Contractual Clauses) and (b) invalidates the EU-U.S. Privacy Shield on which many companies had relied as an
acceptable mechanism for transferring such data from the EU to the United States.

On July 10, 2023, The European Commission adopted an adequacy decision for a new mechanism for transferring data from the EU to the United States –
the EU-US Data Privacy Framework (the “Framework”). The Framework provides EU individuals with several new rights, including the right to obtain
access to their data, or obtain correction or deletion of incorrect or unlawfully handled data. The adequacy decision followed the signing of an executive
order introducing new binding safeguards to address the points raised in the Schrems II decision. Notably, the new obligations were geared to ensure that
data  can  be  accessed  by  US  intelligence  agencies  only  to  the  extent  necessary  and  proportionate  and  to  establish  an  independent  and  impartial  redress
mechanism to handle complaints from Europeans concerning the collection of their data for national security purposes. The European Commission will
continually  review  developments  in  the  US  along  with  its  adequacy  decision.  Adequacy  decisions  can  be  adapted  or  even  withdrawn  in  the  event  of
developments  affecting  the  level  of  protection  in  the  applicable  jurisdiction.  Future  actions  of  EU  data  protection  authorities  are  difficult  to  predict.
Reliance  on  the  Framework  to  enable  cross-border  transfers  without  certain  contractual  and  other  representations  is  dependent  upon  certification  to  the
Framework, which we have not yet done.

Relatedly,  the  United  Kingdom  ("UK")  formally  left  the  European  Union  on  January  31,  2020  (commonly  referred  to  as  Brexit). In  the  UK,  the  Data
Protection  Act  2018  “implements”  and  compliments  the  GDPR,  and  is  effective  in  the  UK. On  June  28,  2021,  the  European  Commission  adopted  an
adequacy decision in respect of transfers of personal data to the UK for a four year period (until June 27, 2025). Similarly, the UK has determined that it
considers all of the European Economic Area to be adequate for the purposes of data protection. This ensures that data flows between the UK and the EU
remain unaffected. The  UK  has  likewise  adopted  a  UK  Extension  to  the  Framework  on  the  same  terms  as  the  European  Commission  for  data  transfers
between the US and the UK, but we have not yet certified to the Framework.

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  ("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 ("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.

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.

35

Non-Patent Exclusivity

Upon NDA approval of a new chemical entity ("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.

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.

Upon approval of the first COSELA marketing application in February 2021, the drug product secured a 5-year period of NCE exclusivity. This exclusivity
period will expire on February 12, 2026.

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.

On April 8, 2021, we filed a request for patent term extension pursuant to 35 U.S.C. § 156 on two of our trilaciclib (COSELA) Orange Book listed patents
(U.S.  8,598,186  and  U.S.  9,487,530).  The  ‘186  patent  claims  the  composition  of  matter  of  trilaciclib  (COSELA).  The  ‘530  patent  claims  the  use  of
trilaciclib (COSELA) to reduce the effect of chemotherapy on healthy cells in a subject being treated for, among other things, small cell lung cancer. For
the ‘186 patent, we requested an extension of 1,162 days. For the ‘530 patent, we requested an extension of 335 days.

36

On February 28, 2022, the USPTO informed the FDA that we had requested a patent term extension on the ‘186 patent and ‘530 patent and that the subject
matter of the patents would be eligible for extension. On September 21, 2022, the FDA informed the USPTO that COSELA was the subject of a new drug
application (NDA), was reviewed by the FDA before commercial marketing, and the patent term extension request was timely filed, all in compliance with
35 U.S.C. § 156. On February 7, 2023, the USPTO informed the FDA that the ‘186 patent and ‘530 patent were eligible for patent term extension and
requested  that  the  FDA  calculate  the  regulatory  review  period.  On  November  28,  2023,  pursuant  to  35  U.S.C.  §  156(d)(2)(A),  the  FDA  informed  the
USPTO and published its determination of COSELA’s regulatory review period in the Federal Register (88 Fed. Reg. 83140 (Nov. 28, 2023)), agreeing
with  our  calculations.  Anyone  with  knowledge  that  any  of  the  dates  as  published  in  the  Federal  Register  are  incorrect  may  request  that  the  FDA
redetermine the extension calculations by January 29, 2024 (60 days from publication) or petition the FDA for a determination regarding whether we acted
with due diligence during the regulatory review period by May 28, 2024 (180-days from publication). If no comment or petition is filed within the time
period provided, the FDA will notify the USPTO that the period for filing a due diligence petition pursuant to the publication has expired and that the FDA
therefore  considers  its  determination  of  the  regulatory  review  period  for  COSELA  to  be  final.  Following  notification  from  the  FDA,  the  USPTO  will
proceed with the final patent term extension eligibility determination.

After reviewing the information provided by the FDA, if the USPTO determines the patents are eligible for extension, the USPTO will then calculate the
length of extension for which the patents are eligible. A Notice of Final Determination will be mailed to us which states the length of extension for which
the patents have been determined to be eligible and the calculations used to determine the length of extension. The Notice of Final Determination provides
a  period,  usually  one  month,  in  which  we  can  request  reconsideration  of  any  aspect  of  the  USPTO’s  determination  as  to  eligibility  or  the  length  of
extension.

Under  35  U.S.C.  156,  only  one  patent  may  be  extended  for  a  single  regulatory  review  period  for  COSELA.  The  USPTO  will  provide  a  period  of  time
(usually  one  month)  for  us  to  elect  the  patent  for  which  extension  is  desired  following  the  receipt  of  the  Notice  of  Final  Determination.  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.

Environmental, Health, and Safety Regulation

We are subject to numerous federal, state and local environmental, health and safety (“EHS”), laws and regulations relating to, among other matters, safe
working  conditions,  product  stewardship,  environmental  protection,  and  handling  or  disposition  of  products,  including  those  governing  the  generation,
storage, handling, use, transportation, release, and disposal of hazardous or potentially hazardous materials, medical waste, and infectious materials that
may be handled by our research laboratories. Some of these laws and regulations also require us to obtain licenses or permits to conduct our operations. If
we fail to comply with such laws or obtain and comply with the applicable permits, we could face substantial fines or possible revocation of our permits or
limitations on our ability to conduct our operations. Certain of our development and manufacturing activities involve use of hazardous materials, and we
believe we are in compliance with the applicable environmental laws, regulations, permits, and licenses. However, we cannot ensure that EHS liabilities
will not develop in the future. EHS laws and regulations are complex, change frequently and have tended to become more stringent over time. Although the
costs to comply with applicable laws and regulations, have not been material, we cannot predict the impact on our business of new or amended laws or
regulations or any changes in the way existing and future laws and regulations are interpreted or enforced, nor can we ensure we will be able to obtain or
maintain any required licenses or permits.

Human Capital

As of December 31, 2023, we had 100 full-time employees, including 72 mapped to selling, general and administrative functions, 25 mapped to research
and development functions and three mapped to costs of goods sold functions. Of these full-time employees, 17 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 to fluctuate slightly as we
continue  to  develop  our  products  and  commercialize  COSELA.  We  consider  our  relations  with  our  employees  to  be  good  and  were  named  by  Triangle
Business Journal as one of the Best Places to Work in 2023 for the second year in a row.

37

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, building a more diverse and inclusive organization, and other initiatives throughout the year.

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, and family leave.

Item 1A. Risk Factors.

Investing  in  our  common  stock  carries  significant  risks.  Before  investing,  carefully  review  the  risks  and  uncertainties  outlined  in  this  Annual  Report,
including our financial statements and related notes. These risks are not exhaustive, and others not currently known to us could also impact our business
and reputation. If any of these risks materialize, it could harm our business, financial condition, liquidity, cash flows, or results of operations, potentially
leading to a decline in the price of our common stock and a loss of 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

•
•
•
•
•
•
•

•

We depend almost entirely on the commercial success of COSELA.
COSELA may fail to achieve the degree of market acceptance for commercial success.
We may not be able to effectively sell or market COSELA, or generate substantial product revenues.
COSELA may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies.
We face substantial competition.
We must comply with post-approval development and regulatory requirements to maintain FDA approval of COSELA.
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.
Any significant cost increases or shortages in the supply of chemotherapy products containing platinum/etoposide or topotecan could
have an adverse impact on our customers’ abilities to order and administer COSELA

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

•
•
•
•

We may need substantial 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 level of indebtedness and debt service obligations could adversely affect our financial condition.

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 additional marketing approvals 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  is  subject  to  extensive  post-marketing  regulatory  requirements  and  could  be  subject  to  additional  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.

39

•

COSELA may cause undesirable side effects that could delay or prevent additional marketing approvals, limit the commercial profile
of additional approved labels, or result in significant negative consequences following additional marketing approvals, if any.

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.

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

Risks related to our intellectual property:

•

If we are unable to obtain, enforce, and maintain intellectual property protection for our current or future 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.

•    Applicable regulatory authorities, including the FDA and the USPTO in the United States, may not agree with our assessment of whether
applicable extensions should be granted, and even if granted, the length of such extensions. Further, 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.

•    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.

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. for COSELA
will succeed or that we will be able to generate revenues necessary to support our goals.

There is no guarantee that we will be successful in our commercialization efforts with respect to COSELA. 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 the amount of revenue generated and the
timing of such revenue.

40

Our  business  currently  depends  heavily  on  our  ability  to  successfully  commercialize  COSELA  in  the  U.S.  to  treat  patients  with  ES-SCLC.  There  is  no
guarantee that the infrastructure, systems, processes, policies, personnel, relationships and materials we have built for the commercialization of COSELA in
the U.S. will be sufficient for us to achieve success at the levels we expect. Our results may also be negatively impacted if we have not adequately sized our
field  teams,  if  our  physician  segmentation  and  targeting  strategy  is  inadequate,  or  if  we  encounter  deficiencies  or  inefficiencies  in  our  infrastructure  or
processes. These issues could hinder our ability to successfully commercialize COSELA, generate significant revenues or profits, or meet our expectations
regarding revenue or profit amounts or timing. Any issues or hurdles related to our commercialization efforts may materially adversely affect our business,
results of operations, financial condition and prospects.

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. Healthcare providers may not accept a change in treatment paradigm for patients with ES-SCLC. We may also encounter challenges related to
reimbursement of COSELA including potential limitations in the scope, breadth, availability, or amount of reimbursement covering COSELA. Similarly,
healthcare settings or patients may determine that the financial burdens of treatment are not acceptable. 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 COSELA;
adverse publicity about COSELA, including the discontinuation of the trials, or favorable publicity about competing products;
our ability to offer COSELA 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 COSELA 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  enhance  our  sales  or  marketing  capabilities,  we  may  not  be  able  to  effectively  sell  or  market  COSELA  or  generate  substantial
product revenues.

To achieve commercial success for COSELA, we must continue to develop our sales, marketing, managerial, and other non-technical capabilities.

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

•
•
•

•

our inability to 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 COSELA;
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.

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.

41

If market opportunities for COSELA are smaller than we estimate or if any FDA approval that we receive for additional indications for COSELA is
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. We have estimated the number of people who have cancer or will develop cancer
and have estimated the amount of approved patient populations 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, any 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.

COSELA 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.

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 Centers for Medicare & Medicaid Services ("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 CMS policies or decisions 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.  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 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.

42

If we or any of our future partners violate the rules or regulations 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 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 enforcement letters from OPDP cite inadequate disclosure of risk
information or misleading presentations about a product’s efficacy. In addition, although physicians may prescribe legally available products for off-label
uses  under  professional  practice  guidelines,  manufacturers  may  not  market  or  promote  such  uses.  Companies  may,  however,  share  truthful  and  not
misleading information that is consistent with the product’s labeling.

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. OPDP issues two types of public letters for drug advertising violations: untitled letters and warning letters. Untitled letters alert
companies of potential violations and direct them to refrain from future violations, while warning letters are issued for more serious offenses and typically
request corrective actions be taken by the company. Although we have not received any such letters from OPDP, we or any of our future partners may
inadvertently violate OPDP’s rules and regulations in the future, which may have a negative impact on our business.

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 additional indications, 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  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.

43

Even though 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.

As a condition of the initial marketing approval of COSELA, we were 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, and 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  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.  Except  for  the  clinical  study  noted  in  (i)  above,  we  have  completed  the  other  post-marketing  requirements
attached to our NDA approval and submitted them to the FDA for review.

The FDA may withdraw approval of COSELA if evidence generated from the post-approval studies demonstrates that COSELA is not shown to be safe or
effective  under  the  conditions  of  use,  we  disseminate  false  or  misleading  promotional  materials  relating  thereto,  among  other  potential  administrative
actions that could be taken against the drug product or against our company.

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 commercialize 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 which prohibits, among other things, persons or entities from knowingly and willfully soliciting,
offering, receiving or providing any remuneration (including any kickback, bribe or certain rebates), directly or indirectly, overtly or
covertly,  in  cash  or  in  kind,  in  return  for,  either  the  referral  of  an  individual  or  the  purchase,  lease,  or  order,  or  arranging  for  or
recommending the purchase, lease, or order of any good, facility, item or service, for which payment may be made, in whole or in
part, under a federal healthcare program such as Medicare and Medicaid. A person or entity does not need to have actual knowledge
of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a violation;
the federal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, which prohibit, among other
things, individuals or entities from knowingly presenting, or causing to be presented, to the federal government, claims for payment
or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a false record or statement material
to a false or fraudulent claim, or from knowingly making or causing to be made 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 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;
HIPAA,  which  imposes  criminal  and  civil  liability  for,  among  other  things,  knowingly  and  willfully  executing,  or  attempting  to
execute,  a  scheme  to  defraud  any  healthcare  benefit  program,  or  knowingly  and  willfully  falsifying,  concealing  or  covering  up  a
material fact or making any materially false statement, in connection with the delivery of, or payment for, healthcare benefits, items
or services. Similar to the 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;

44

•

•

•

•

•

•

the federal Physician Payments Sunshine Act, which requires certain require manufacturers of drugs, devices, biologics and medical
supplies  for  which  payment  is  available  under  Medicare,  Medicaid  or  the  Children’s  Health  Insurance  Program,  with  certain
exceptions,  to  report  annually  to  CMS  information  related  to  payments  and  other  "transfers  of  value"  to  physicians  (defined  to
include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors),  certain  advanced  nonphysician  practitioners,  and  teaching
hospitals, as well as ownership and investment interests held by physicians and their immediate family members;
HIPAA,  as  amended  by  HITECH  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;
some state laws that require pharmaceutical companies to report information on the pricing of certain drug products; and some state
and local laws that require the registration of pharmaceutical sales representatives; 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  current  and  future  business  arrangements  with  third  parties  will  comply  with  applicable  healthcare  and  privacy  laws  and
regulations will involve ongoing substantial costs. It is possible that governmental authorities will 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  penalties,
including  civil,  criminal  and  administrative  penalties,  damages,  fines,  disgorgement,  imprisonment,  exclusion  from  participation  in  government-funded
healthcare  programs,  such  as  Medicare  and  Medicaid,  integrity  oversight  and  reporting  obligations,  contractual  damages,  reputational  harm,  diminished
profits and future earnings and the curtailment or restructuring of our operations. Defending against any such actions can be costly and time-consuming and
may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought
against us, our business may be impaired. Further, if any of the physicians or other healthcare providers or entities with whom we expect to do business are
found  to  violate  applicable  laws  or  regulations,  they  may  be  subject  to  significant  criminal,  civil  or  administrative  sanctions,  including  exclusions  from
government-funded healthcare programs.

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 EU, 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.

Any  significant  cost  increases  or  shortages  in  platinum/etoposide  or  topotecan  chemotherapy  could  hinder  our  customers’  ability  to  order  and
administer COSELA, potentially affecting its sales.

As COSELA’s efficacy relies on its administration in conjunction with specific chemotherapy regimens containing platinum/etoposide or topotecan, any
significant  cost  increases  or  supply  shortages  of  these  chemotherapy  products  could  have  an  adverse  impact  on  our  customers’  abilities  to  order  and
administer COSELA, and as a result, could impact the sales of COSELA.

45

If  manufacturers  face  production  challenges  for  these  chemotherapy  products  due  to supply  chain  disruptions  or  manufacturing  issues,  or  if  customers
struggle to obtain an adequate supply due to price fluctuations or shortages, they may reduce orders of COSELA. This could lead to treatment delays or
disruptions for ES-SCLC, affecting patient outcomes and treatment schedules.

As of the date of this report, the FDA has reported shortages in the supply of certain platinum-based chemotherapy products, including Cisplatin (since
February 2023) and Carboplatin (since April 2023). We are actively monitoring any issues related to the availability of these chemotherapy products and
their potential impact on the use of COSELA. Any significant disruption in the supply chain or demand for these chemotherapy products could adversely
impact our sales of COSELA and therefore adversely affect our business, results of operations, and financial conditions.

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.

Developing  pharmaceutical  drugs  is  a  capital-intensive  venture.  We  expect  increasing  expenses  for  our  ongoing  activities,  particularly  as  we  support
commercial activities, conduct clinical trials, and seek marketing approval for, COSELA in any 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 to pursue new indications and/or geographies for COSELA or otherwise if we expand more rapidly than currently anticipated. 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 and to achieve our business objectives. 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.

Because the length of time and activities associated with successful commercialization, research and development of COSELA is highly uncertain, we are
unable to estimate the actual funds we will require. Our future capital needs will depend on several factors and could increase significantly due to various
reasons, including:

•

•
•
•
•

•
•

•

•
•

•
•
•

•

the costs of commercialization activities, including product sales, marketing, manufacturing and distribution of COSELA for which
we received marketing approval or any of our product candidates for which we receive marketing approval;
the scope, progress, results and costs of nonclinical 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 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  agreements  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;
the extent to which we acquire or in-license product candidates and technologies, and the terms of such in-licenses;
the  potential  benefit  of  the  NMPA's  conditional  approval  for  our  products  and  product  candidates  and  our  ability  to  provide
comprehensive clinical data from post-approval clinical research;
revenue received from commercial sales of COSELA and any future product candidates;
our ability to meet the required financial covenants under our loan agreement;
the  costs  of  preparing,  filing  and  prosecuting  patent  applications,  maintaining  and  enforcing  our  intellectual  property  rights  and
defending intellectual property-related claims; and
global economic uncertainty, rising inflation, rising interest rates, market disruptions and volatility in commodity prices.

46

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.

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.

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  $48.0  million  for  the  year  ended  December  31,  2023,
$147.6 million for the year ended December 31, 2022, and $148.4 million for the year ended December 31, 2021. As of December 31, 2023, we had an
accumulated deficit of $780.0 million. It may be several years, if ever, before we become profitable. To date, we have financed our operations primarily
through proceeds from our initial public offering, our follow-on stock offerings, our loan agreement with Hercules Capital, Inc. ("Hercules") and proceeds
from our license agreements. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future.

To date, inflation has not had a material impact on our business, but if the global inflationary trends continue, we expect appreciable increases in clinical
trial, selling, labor, and other operating costs. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset
such higher costs through price increases of our product. Our inability or failure to do so could adversely affect our business, financial condition and results
of operations.

In  addition,  currently  there  is  a  conflict  involving  Russia  and  Ukraine  and  a  conflict  involving  Israel  and  Hamas,  and  these  conflicts  may  directly  or
indirectly impact our contract research organizations, clinical data management organizations, and clinical investigators’ ability to conduct certain of our
trials in Eastern European countries, and may increase our product development costs and materially harm our business.

The net losses we incur may fluctuate significantly from quarter to quarter. We anticipate our research and development, commercial activities, and selling,
general and administrative expenses will continue to increase in connection with our ongoing and future activities.

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 trilaciclib, 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.

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. A decline in the value of our company could also cause you to lose
all or part of your investment.

47

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. This could result in us relinquishing 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.

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.

As of December 31, 2023, the Company has $50.0 million outstanding under our loan agreement with Hercules (the "Hercules Loan Agreement"), with a
maturity  date  of  November  1,  2026.  Our  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. As of December 31, 2023, we were in compliance with all covenants. 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. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -
Liquidity and Capital Resources - Loan and Security Agreement" section of this Annual Report for more details.

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 waste. 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.

48

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.

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% 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. We continue to maintain a valuation allowance on the remaining NOLs as we believe 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, 2023, our federal and state net operating loss carryforwards amounted to $550.7 million and $401.2 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 development of COSELA

If  we  are  unable  to  successfully  develop  and  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 COSELA. Our ability to generate product revenues will
depend  on  the  successful  development  and  commercialization  of  COSELA  for  additional  indications.  COSELA  will  require  additional  development,
management  of  development  and  manufacturing  activities,  marketing  approval 
jurisdictions,  obtaining  manufacturing  supply,
commercialization activities, substantial investment and significant marketing efforts.

in  multiple 

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:

•
•
•
•
•

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 COSELA, including successful completion of clinical trials;
obtain required marketing approvals for the development and commercialization of additional indications for COSELA, which may
become more difficult considering the discontinuation of clinical trials;

49

•

•
•

•
•
•
•
•

obtain, maintain, and enforce 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., maintain, and enforce healthcare coverage and adequate reimbursement;
maintain a continued acceptable safety profile for COSELA;
develop and maintain any strategic relationships;
enforce and defend intellectual property rights and claims; and
manage  our  spending  as  costs  and  expenses  increase  due  to  preclinical  development,  clinical  trials,  marketing  approvals  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 any future clinical trials, development of additional indications for COSELA may
be delayed or prevented, which would have a material adverse effect on our business.

Identifying and qualifying patients to participate in future clinical trials for additional indications for COSELA is critical to our success. We may not be
able to initiate or continue future clinical trials for COSELA if we are unable to locate and enroll a sufficient number of eligible patients to participate in
these  trials  as  required  by  the  FDA  or  similar  regulatory  authorities  outside  the  United  States.  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.

Congress also recently amended the FDC Act to require sponsors of a Phase 3 clinical trial, or other “pivotal study” of a new drug to support marketing
authorization, to design and submit a diversity action plan for such clinical trial. The action plan must describe appropriate diversity goals for enrollment,
as well as a rationale for the goals and a description of how the sponsor will meet them. Accordingly, we must submit a diversity action plan to the FDA by
the  time  we  submit  a  Phase  3  trial,  or  pivotal  study,  protocol  to  the  agency  for  review,  unless  we  are  able  to  obtain  a  waiver  for  some  or  all  of  the
requirements for a diversity action plan. It is unknown at this time how the diversity action plan may affect the planning and timing of any future Phase 3
trial for our product candidates or what specific information FDA will expect in such plans. However, initiation of such trials may be delayed if the FDA
objects to our proposed diversity action plans for any future Phase 3 trial for our product candidates, and we may experience difficulties recruiting a diverse
population of patients in attempting to fulfill the requirements of any approved diversity action plan.

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 additional indications for 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.

50

Interim,  “topline”  and  preliminary  data  from  our  clinical  trials  that  we  announce  or  publish  from  time  to  time  may  change  as  more  patient  data
become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose preliminary or topline data from our preclinical studies and clinical trials, which are based on a preliminary
analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the
data related to the particular study or trial. We make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not
have received or had the opportunity to fully and carefully evaluate all data. As a result, the topline or preliminary results that we report may differ from
future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully
evaluated.  Topline  data  also  remain  subject  to  audit  and  verification  procedures  that  may  result  in  the  final  data  being  materially  different  from  the
preliminary data we previously published or reported. As a result, topline data should be viewed with caution until the final data are available.

From time to time, we may also disclose interim data from our preclinical studies and clinical trials. Interim data from clinical trials that we may complete
are  subject  to  the  risk  that  one  or  more  of  the  clinical  outcomes  may  materially  change  as  patient  enrollment  continues  and  more  patient  data  become
available. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of
interim data by us could result in volatility in the price of our common stock.

Further,  others,  including  regulatory  agencies,  may  not  accept  or  agree  with  our  assumptions,  estimates,  calculations,  conclusions  or  analyses  or  may
interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of
COSELA and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on
what  is  typically  extensive  information,  and  you  or  others  may  not  agree  with  what  we  determine  is  material  or  otherwise  appropriate  information  to
include in our disclosure.

If  the  interim,  topline,  or  preliminary  data  that  we  report  differ  from  actual  results,  or  if  others,  including  regulatory  authorities,  disagree  with  the
conclusions reached, our ability to obtain approval for, and commercialize, COSELA may be harmed, which could harm our business, operating results,
prospects or financial condition.

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.

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 or in non-US markets.

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  for  each  of  its
intended uses. 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.

51

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  or  statistical
analysis plan 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;
delays in reaching, or failure to reach, agreement with the FDA on a pivotal study's mandatory diversity action plan;
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 COSELA may be larger 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, an IRB, or a Data Safety Monitoring Board, 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.

52

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.

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  early  anti-tumor  efficacy  data  in
colorectal cancer showed patients receiving placebo are favored compared to trilaciclib and led to the decision to discontinue PRESERVE 1. In addition,
we  may  be  unsuccessful  in  developing  COSELA  for  breast  cancer.  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.

Our development of COSELA, a CDK4/6 inhibitor to decrease the incidence of chemotherapy-induced myelosuppression, is novel 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.  Even  though  COSELA  has  demonstrated  positive  results  in  clinical  trials  for  ES-SCLC,  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 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.

Before we can commercialize COSELA in additional indications, each additional indication must be approved by the FDA pursuant to a supplemental 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.

53

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. For example, our early anti-tumor
efficacy data in colorectal cancer showed patients receiving placebo were favored compared to trilaciclib and led to the decision to discontinue PRESERVE
1. 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 nonclinical 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 relevant regulatory authorities. In each proposed indication for use, 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 also 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
nonclinical  studies  or  clinical  trials.  COSELA  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 each 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;
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, sNDA, MAA 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.

If COSELA is approved for additional indications, it may 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.

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  requirements.  The  FDA  or  a  comparable
foreign regulatory authority may also impose requirements for costly post-marketing nonclinical 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. See risks described above, under "If we or any of our future partners
violate the rules or regulations 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 or other regulatory authorities."

54

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 EU or applicable local country requirements regarding safety monitoring or pharmacovigilance can also result in significant financial
penalties. Similarly, failure to comply with the EU or applicable local country 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 additional
indications for 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 ("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 ASP 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. More recently, 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 drug products
covered under Medicare Part B report the product's ASP to CMS beginning on January 1, 2022, subject to enforcement via civil monetary penalties.

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;

55

•

•

•
•
•
•
•
•

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.

The  Infrastructure  Investment  and  Jobs  Act may  impact  our  future  strategies  and  results  of  operations  as  it  pertains  to  COSELA.  Passed  by  the  117th
United  States  Congress  and  signed  into  law  by  President  Joe  Biden  on  November  15,  2021,  the  Infrastructure  Investment  and  Jobs  Act  is  landmark
legislation which may significantly impact the pharmaceutical industry. As another example, the American Rescue Plan Act of 2021 included a provision
that eliminated the statutory cap on rebates that drug manufacturers pay to Medicaid. Beginning in January 2024, Medicaid rebates are no longer being
capped at 100 percent of the quarterly AMP.

Moreover,  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.  One  significant  example  of  recent  legislative  action  is  the  Inflation
Reduction Act of 2022 (the "IRA"), which was signed into law in August 2022 and included several measures intended to lower the cost of prescription
drugs.  Specifically,  the  IRA  authorizes  and  directs  CMS  to  set  drug  price  caps  for  certain  high-cost  Medicare  Part  B  and  Part  D  qualified  drugs.  A
manufacturer of drug products covered by Medicare Parts B or D must now pay a rebate to the federal government if their drug product’s price increases
faster  than  the  rate  of  inflation.  This  calculation  is  made  on  a  drug  product  by  drug  product  basis  and  the  amount  of  the  rebate  owed  to  the  federal
government is directly dependent on the volume of a drug product that is paid for by Medicare Parts B or D. Additionally, starting for payment year 2026,
CMS  will  negotiate  drug  prices  annually  for  a  select  number  of  single  source  Part  D  drugs  without  generic  competition.  CMS  will  also  negotiate  drug
prices for a select number of Part B drugs starting for payment year 2028. If a drug product is selected by CMS for negotiation, it is expected that the
revenue  generated  from  such  drug  will  decrease.  CMS  has  begun  to  implement  these  new  authorities  and  entered  into  the  first  set  of  agreements  with
pharmaceutical  manufacturers  to  conduct  price  negotiations  in  October  2023.  However,  the  IRA's  impact  on  the  pharmaceutical  industry  in  the  United
States  remains  uncertain,  in  part  because  multiple  large  pharmaceutical  companies  and  other  stakeholders  (e.g.,  the  U.S.  Chamber  of  Commerce)  have
initiated  federal  lawsuits  against  CMS  arguing  the  program  is  unconstitutional  for  a  variety  of  reasons,  among  other  complaints.  Those  lawsuits  are
currently ongoing. In addition, the IRA creates significant changes to the Medicare Part D benefit design by capping Part D beneficiaries' annual out-of-
pocket spending at $2,000 beginning in 2025. The IRA is still subject to rulemaking (with more information to come via guidance documents from the
responsible federal agencies) and at this time, we cannot be sure whether additional or related legislation or rulemaking will be issued or enacted, or what
impact, if any, such changes will have on the profitability of COSELA, in the future.

We expect that the IRA, as well as other federal 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.

56

We also expect that state and local governments in the U.S. will continue to consider legislation directed at lowering the total cost of healthcare. Individual
states in the United States have 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.  For  example,  in  recent  years,  several  states  have  formed
PDABs.  Much  like  the  IRA’s  drug  price  negotiation  program,  these  PDABs  have  attempted  to  implement  upper  payment  limits  on  drugs  sold  in  their
respective states in both public and commercial health plans. As an example, in August 2023, Colorado’s PDAB announced a list of five prescription drugs
that would undergo an affordability review. The effects of these efforts remain uncertain pending the outcomes of several federal lawsuits challenging state
authority to regulate prescription drug payment limits.

In  addition,  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.

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 indications 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.

57

We may incur material losses and costs as a result of product liability and warranty claims that may be brought against us and recalls, which may
adversely affect our results of operations and financial condition. Furthermore, as a pharmaceutical company, we face an inherent risk of damage to
our reputation if one or more of our products are, or are alleged to be, defective.

Our business exposes us to potential product liability risks that are inherent in the design, manufacture and marketing of prescription medical products. In
particular,  COSELA  is  used  to  treat  seriously  ill  cancer  patients  who  are  undergoing  chemotherapy.  Manufacturing  defects  or  inadequate  disclosure  of
product-related risks with respect to COSELA or other products we may commercialize in the future could result in an unsafe condition or injury to, or
death of, the patient. As a result, we face an inherent risk of damage to our reputation if one or more of our products are, or are alleged to be, defective.
Although  we  carry  product  liability  insurance,  we  may  be  exposed  to  product  liability  and  warranty  claims  in  the  event  that  our  products  actually  or
allegedly fail to perform as expected or the use of our products results, or is alleged to result, in bodily injury. The outcome of litigation, particularly any
class-action  lawsuits,  is  difficult  to  quantify.  Plaintiffs  often  seek  recovery  of  very  large  or  indeterminate  amounts,  including  punitive  damages.  The
magnitude of the potential losses relating to these lawsuits may remain unknown for substantial periods of time and the cost to defend against any such
litigation  may  be  significant.  Accordingly,  we  could  experience  material  warranty  or  product  liability  losses  in  the  future  and  incur  significant  costs  to
defend these claims.

In addition, if any of our products are, or are alleged to be, defective or unsafe, we may voluntarily initiate, or be required by FDA or other applicable
regulators, to initiate a recall of that product from the marketplace. In the event of a recall, we may experience lost sales and be exposed to individual or
class-action litigation claims and reputational risk. Product liability, warranty and recall costs may have a material adverse effect on our business, financial
condition and results of operations.

The FDA and other government agencies could prevent the timely development and commercialization of new indications of COSELA due to concerns
about the quality of 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 Simcere, which was amended on April 28, 2023, for the development 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. There can be no assurance that the FDA, EMA or any applicable
foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction, including any trials conducted
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.

The  government  of  the  People’s  Republic  of  China  (“PRC”)  may  determine  that  our  licensing  agreement  with  Simcere  is  not  in  compliance  with
applicable PRC laws, rules and regulations.

There are uncertainties regarding the interpretation and application of PRC laws, rules and regulations, including, but not limited to, the laws, rules and
regulations governing the validity and enforcement of our licensing agreement with Simcere. Because the interpretations of many laws, regulations and
rules are not always uniform, the interpretation of statutes and regulations may be subject to government policies reflecting domestic political agendas and
enforcement of existing laws or contracts based on existing law may be uncertain and sporadic. We cannot assure you that the PRC regulatory authorities
will not determine that our licensing agreement with Simcere in China does not violate PRC laws, rules or regulations. If the PRC regulatory authorities
determine that this licensing agreement is in violation of applicable PRC laws, rules or regulations, it may become invalid or unenforceable, which will
adversely affect our operations. The PRC has broad discretion in dealing with violations of laws and regulations, including levying fines, revoking business
and other licenses and requiring actions necessary for compliance. In particular, licenses and permits issued or granted by relevant governmental agencies
may be revoked at a later time by other regulatory agencies. We cannot predict the effect of the interpretation of existing or new PRC laws or regulations on
our business. Any of these or similar actions could significantly disrupt our operations or restrict us from conducting a substantial portion of our operations,
which could materially and adversely affect our business, financial condition and results of operations.

58

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
EU and many other jurisdictions, we or our third-party collaborators must obtain separate marketing approvals and comply with numerous and varying
regulatory requirements. 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  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.

59

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 commercial-stage biopharmaceutical company, and, as of December 31, 2023, had 100 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.

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 or from universities and research institutions for the hiring of scientific and clinical personnel. 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.

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

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, travel
restrictions, ability to hire and retain key personnel and accept payment of user fees, and statutory, regulatory, and policy changes. Average review times at
the FDA have fluctuated in recent years. In addition, government funding of the SEC and other government agencies on which our operations may rely,
including those that fund research and development activities is inherently fluid and unpredictable.

Disruptions  at  the  FDA  and  other  agencies  may  also  slow  the  time  necessary  for  new  drugs  to  be  reviewed  and/or  approved  by  necessary  government
agencies, which would adversely affect our business. For example, over the last several years, including most recently beginning on December 22, 2018,
the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC
and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the
FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further,  future  government
shutdowns could impact our ability to access the public markets and obtain necessary capital to properly capitalize and continue our operations.

60

Public health threats could have a material impact on our business, financial condition and results of operations, including our commercial operations
and sales, clinical trials and non-clinical trials.

The COVID-19 worldwide pandemic, which was recently declared no longer a public health emergency both globally and in the United States, presented
substantial public health and economic challenges and affected our employees, customers, patients, physicians and other healthcare providers, communities
and  business  operations,  as  well  as  the  U.S.  and  global  economies  and  financial  markets.  International  and  U.S.  governmental  authorities  in  impacted
regions took multiple and diverse actions in an effort to slow the spread of COVID-19 and variants of the virus, including issuing varying forms of “stay-at-
home”  orders.  Such  measures  taken  by  the  governmental  authorities  to  respond  to  any  future  epidemic  or  pandemic  disease  outbreaks  could  severely
impact our ability to successfully commercialize COSELA or develop and commercialize COSELA in additional indications, disrupt the supply chain and
the manufacture or shipment of drug substances and finished drug product for use in our clinical trials and research and non-clinical studies and, delay,
limit or prevent our employees from continuing research and development activities, impede our clinical trial initiation and recruitment and the ability of
patients to continue in clinical trials, including due to measures taken that may limit social interaction or prevent reopening of high-transmission settings,
impede testing, monitoring, data collection and analysis and other related activities, any of which could delay our non-clinical studies and clinical trials and
increase our development costs, and have a material adverse effect on our business, financial condition and results of operations. Any future epidemic or
pandemic  disease  outbreak,  including  any  resurgence  of  COVID-19,  could  also  potentially  further  affect  the  operations  of  the  FDA  or  other  regulatory
authorities,  which  could  result  in  delays  in  meetings  related  to  our  planned  clinical  trials.  Any  future  epidemic  disease  outbreak  may  have  an  adverse
impact on global economic conditions which could have an adverse effect on our business and financial condition, including impairing our ability to raise
capital when needed.

We may fail to comply with evolving privacy and data protection laws, which could adversely affect our business, results of operations and financial
condition.

In  California,  the  California  Consumer  Privacy  Act  (“CCPA”),  which  became  effective  in  2020,  broadly  defines  personal  information,  gives  California
residents expanded individual privacy rights and protections and provides for civil penalties for violations and a private right of action for data breaches.
Further, the California Privacy Rights Act (“CPRA”), which became effective in 2023 and amends the CCPA, creates additional obligations with respect to
processing  and  storing  personal  information.  We  continue  to  monitor  developments  related  to  the  CCPA  and  anticipate  additional  costs  and  expenses
associated with CPRA compliance as regulations are enacted by the California Privacy Protection Agency. While there is an exception for protected health
information that is subject to HIPAA and clinical trial regulations, the CCPA may impact our business activities as a “Business” defined under the CCPA.
Unlike other state privacy laws, the CCPA also regulates personal information collected in a business to business and in human resources contexts. Further,
there continues to be some uncertainly about how provisions of the CCPA and the new regulations will be interpreted and how the law will be enforced.

In addition to the CCPA, broad consumer privacy laws recently went into effect in Virginia on January 1, 2023, in Colorado and Connecticut on July 1,
2023, and in Utah on December 31, 2023. New privacy laws will also become effective in Florida, Montana and Texas in 2024, in Tennessee and Iowa in
2025,  and  in  Indiana  in  2026  and  numerous  other  states  are  considering  new  privacy  laws.  Furthermore,  other  U.S.  states,  such  as  New  York,
Massachusetts, and Utah have enacted stringent data security laws and numerous other states have proposed similar privacy laws.

The existence of differing comprehensive privacy laws in different states in the country will make our compliance obligations more complex and costly and
may require us to modify our data processing practices and policies and to incur substantial costs and potential liability in an effort to comply with such
legislation.

61

In the EU and the UK, we may also face particular privacy, data security, and data protection risks in connection with requirements of the GDPR. The
GDPR applies to any company established in the EU as well as to those outside the EU if they collect and use personal data in connection with the offering
of  goods  or  services  to  individuals  in  the  EU  or  the  monitoring  of  their  behavior.  We  currently  conduct  clinical  trials  and  engage  in  regulatory  and
commercial operations in the EEA and the UK. As a result, The GDPR imposes a broad range of data protection obligations on companies subject to the
GDPR,  including,  for  example,  imposing  obligations  on  companies  around  how  they  process  personal  data,  stricter  requirements  relating  to  processing
health and other sensitive data, ensuring there is a legal basis to justify the processing of personal data, stricter requirements relating to obtaining consent of
individuals, expanded disclosures about how personal information is to be used, limitations on retention of information, mandatory data breach notification
requirements,  implementing  safeguards  to  protect  the  security  and  confidentiality  of  personal  data,  taking  certain  measures  on  engagement  with  third
parties, restrictions on transfers outside of the EU to third countries deemed to lack adequate privacy protections (such as the U.S.), and has created onerous
new obligations and liabilities on services providers or data processors. Non-compliance with the GDPR may result in monetary penalties of up to €20
million  or  4%  of  worldwide  revenue,  whichever  is  higher. Moreover,  data  subjects  can  claim  damages  resulting  from  infringement  of  the  GDPR.  The
GDPR  further  grants  non-profit  organizations  the  right  to  bring  claims  on  behalf  of  data  subjects. The  GDPR  and  other  changes  in  laws  or  regulations
associated with the enhanced protection of certain types of personal data, such as healthcare data or other sensitive information, could greatly increase our
cost  of  providing  our  products  and  services  or  even  prevent  us  from  offering  certain  services  in  jurisdictions  that  we  may  operate  in.  The  GDPR  may
increase our responsibility and liability in relation to personal data that we process where such processing is subject to the GDPR, and we may be required
to put in place additional mechanisms to ensure compliance with the GDPR, including as implemented by individual countries. Ensuring our continued
compliance  with  the  GDPR  is  a  rigorous  and  time-intensive  process  that  may  increase  our  cost  of  doing  business  or  require  us  to  change  our  business
practices, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection with our
European activities.

In particular, member states of the EEA (the “Member States”) have implemented national laws which may partially deviate from the GDPR and impose
different and more restrictive obligations from country to country, so that we do not expect to operate in a uniform legal landscape in the EU. Also, as it
relates to processing and transfer of genetic data, the GDPR specifically allows the Member States to enact laws that impose additional and more specific
requirements or restrictions, and European laws have historically differed quite substantially in this field, leading to additional uncertainty.

In addition, we must also ensure that we maintain adequate safeguards to enable the transfer of personal data outside of the EEA, in particular to the U.S.,
in compliance with EEA data protection laws. We expect that we will continue to face uncertainty as to whether our efforts to comply with our obligations
under European privacy laws will be sufficient. The EU and U.S. have adopted an adequacy decision for the EU U.S. Data Privacy Framework, which
entered into force on July 11, 2023. This Framework provides that the protection of personal data transferred between the EU and the U.S. is comparable to
that offered in the EU. This provides a further avenue to ensuring transfers to the U.S. are carried out in accordance with the GDPR. The Framework could
be subject to legal challenge like its predecessor frameworks, and we have not yet certified participation with the Framework.

Many  jurisdictions  outside  of  Europe  are  considering  and/or  enacting  comprehensive  data  protection  legislation  that  could  have  an  impact  on  market
expansion and clinical trials. For example, we are the named sponsor for two clinical trials in China and developments in privacy and data security in China
may require adjustments to our business practices with respect to these personal information protection laws and regulations.

We  also  continue  to  see  jurisdictions  imposing  data  localization  laws. These  regulations  may  interfere  with  our  intended  business  activities,  inhibit  our
ability to expand into those markets or prohibit us from continuing to offer services in those markets without significant additional costs.

Because the interpretation and application of many privacy and data protection laws (including those state laws in the U.S. and the GDPR), commercial
frameworks,  and  standards  are  uncertain,  it  is  possible  that  these  laws,  frameworks,  and  standards  may  be  interpreted  and  applied  in  a  manner  that  is
inconsistent with our existing data management practices and policies. If so, in addition to the possibility of fines, lawsuits, breach of contract claims, and
other claims and penalties, we could be required to fundamentally change our business activities and practices or modify our solutions, which could have
an adverse effect on our business. Any inability to adequately address privacy and security concerns, even if unfounded, or comply with applicable privacy
and security or data security laws, regulations, and policies, could result in additional cost and liability to us, damage our reputation, inhibit our ability to
conduct trials, and adversely affect our business.

62

Our business and operations could suffer in the event of system failures, cyberattacks, or deficiency in our cyber security.

We  rely  on  information  technology  systems  and  networks,  including  third-party  "cloud-based"  service  providers,  and  our  third-party  CROs,  to  process,
transmit  and  store  electronic  information  in  connection  with  our  business  activities.  This  includes  crucial  systems  such  as  email,  other  communication
tools, electronic document repositories, and archives. 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. Cyberattacks could include wrongful conduct by hostile foreign
governments, industrial espionage, wire fraud and other forms of cyber fraud, the deployment of harmful malware, denial-of-service, social engineering
fraud or other means to threaten data security, confidentiality, integrity and availability. Furthermore, because the techniques used to obtain unauthorized
access  to,  or  to  sabotage,  systems  change  frequently  and  often  are  not  recognized  until  launched  against  a  target,  we  may  be  unable  to  anticipate  these
techniques or implement adequate preventative measures. We may also experience security breaches that may remain undetected for an extended period. A
successful cyberattack could cause serious negative consequences for us, including, without limitation, the disruption of operations, the misappropriation of
confidential business information, including financial information, trade secrets, financial loss and the disclosure of corporate strategic plans. There can be
no assurance that we will be successful in preventing cyber-attacks or successfully mitigating their effects. There have been no cybersecurity incidents that
have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition.

We  have  little  or  no  control  over  the  security  measures  and  computer  systems  of  our  third-party  CROs,  clinical  trial  sites  and  other  contractors  and
consultants and we may have insufficient recourse against such third parties in the event that they become subject to disruptions or security breaches, and
may have to expend significant resources to mitigate the impact of such an event. 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.

We  take  measures  to  protect  sensitive  data  from  unauthorized  access,  use  or  disclosure,  but  our  information  technology  and  infrastructure  may  be
vulnerable to attacks by hackers or viruses or breached due to personnel error, malfeasance, or other malicious or inadvertent disruptions. Any such access,
breach,  or  other  loss  of  information  could  result  in  legal  claims  or  proceedings,  liability  under  domestic  or  foreign  privacy,  data  protection,  and  data
security laws and could subject us to fines and penalties or class action litigation. The costs related to significant security breaches or disruptions could be
material and could exceed the limits of the cybersecurity insurance we maintain against such risks.

The interplay of federal and state laws may be subject to varying interpretations by courts and government agencies, creating complex compliance issues
for us and data we receive, use and share, potentially exposing us to additional expense, adverse publicity and liability. Further,  as  regulatory  focus  on
privacy issues continues to increase and laws and regulations concerning the protection of personal information expand and become more complex, these
potential risks to our business could intensify. Changes in laws or regulations associated with the enhanced protection of certain types of sensitive data, for
the treatment of health and patient data, along with increased customer demands for enhanced data security infrastructure, could greatly increase our cost of
providing our products, decrease demand for our products, reduce our revenues and/or subject us to additional liabilities.

63

Artificial intelligence presents risks and challenges that can impact our business including by posing security risks to our confidential information,
proprietary information, and personal data.

Issues in the development and use of artificial intelligence, combined with an uncertain regulatory environment, may result in reputational harm, liability,
or other adverse consequences to our business operations. We may adopt and integrate generative artificial intelligence tools into our systems for specific
use  cases  reviewed  by  legal  and  information  security. Our  vendors  may  incorporate  generative  artificial  intelligence  tools  into  their  offerings,  and  the
providers of these generative artificial intelligence tools may not meet existing or rapidly evolving regulatory or industry standards with respect to privacy
and data protection and may inhibit our or our vendors’ ability to maintain an adequate level of service and experience. If we, our vendors, or our third-
party partners experience an actual or perceived breach or privacy or security incident because of the use of generative artificial intelligence, we may lose
valuable intellectual property and confidential information and our reputation and the public perception of the effectiveness of our security measures could
be harmed. Any of these outcomes could damage our reputation, result in the loss of valuable property and information, and adversely impact our business.

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. 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,  which  may  increase  our
expenses or reduce our ability to generate or increase our revenue. 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. 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.

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, which 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.

64

Our  employees,  principal  investigators,  clinical  trial  site  personnel,  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, clinical trial site personnel, 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.  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 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  or  the  third  parties  upon  which  we  depend  may  be  adversely  affected  by  general  political,  unstable  market  and  economic  conditions  and  other
events beyond our control and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

We have become increasingly subject to the risks arising from adverse changes in market and economic and political conditions, both domestically and
globally, including trends toward protectionism and nationalism, other unfavorable changes in economic conditions, as well as disruptions in global credit
and financial markets, such as failures and instability in U.S. and international banking systems, downgrades of the U.S. credit rating, rising interest rates,
slower  economic  growth  or  a  recession,  and  other  events  beyond  our  control,  such  as  epidemics,  political  instability,  and  armed  conflicts  and  wars,
including the ongoing conflict between Russia and Ukraine and the war between Israel and Hamas.

The U.S. debt ceiling and budget deficit concerns have increased the possibility of credit-rating downgrades and economic slowdowns, or a recession in the
United States. On August 1, 2023, Fitch Ratings downgraded the United States’ long-term foreign currency issuer default rating to AA+ from AAA as a
result of these repeated debt ceiling and budget deficit concerns. The impact of this or any further downgrades to the U.S. government’s sovereign credit
rating or its perceived creditworthiness could adversely affect the U.S. and global financial markets and economic conditions.

If  the  equity  and  credit  markets  deteriorate,  it  may  make  any  necessary  equity  or  debt  financing  more  difficult  to  secure,  more  costly  or  more  dilutive.
Failure to secure any necessary financing in a timely manner and on favorable terms could harm our growth strategy, financial performance and stock price
and could require us to delay or abandon plans with respect to our business, including clinical development plans. If the financial institutions with which
we do business enter receivership or become insolvent in the future, there is no guarantee that the Department of the Treasury, the Federal Reserve and the
Federal Deposit Insurance Corporation (“FDIC”) will intercede to provide us and other depositors with access to balances in excess of the $250,000 FDIC
insurance limit, that we would be able to access our existing cash, cash equivalents and investments, that we would be able to maintain any required letters
of credit or other credit support arrangements, or that we would be able to adequately fund our business for a prolonged period of time or at all, any of
which could have a material adverse effect on our business, financial condition and results of operations. We cannot predict the impact that the high market
volatility and instability of the banking sector more broadly could have on economic activity and our business in particular. In addition, there is a risk that
one  or  more  of  our  current  service  providers,  manufacturers  or  other  third  parties  with  which  we  conduct  business  may  not  survive  difficult  economic
times, which could directly affect our ability to attain our operating goals on schedule and on budget.

65

The effects of current and future economic and political conditions and other events beyond our control on us, patients, our third party vendors, including
clinical trial sites, and our partners could severely disrupt our operations and have a material adverse effect on our business. If the critical infrastructure of a
third party vendor was disrupted, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. We may
incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans.

Political uncertainty may have an adverse impact on our operating performance and results of operations.

General political uncertainty may have an adverse impact on our operating performance and results of operations. In particular, the United States continues
to experience significant political events that cast uncertainty on global financial and economic markets, especially in light of the upcoming presidential
election. It is presently unclear exactly what actions a new administration in the United States would implement, and if implemented, how these actions
may impact the pharmaceutical industry in the United States.

Climate change or legal, regulatory or market measures to address climate change may negatively affect our business, results of operations, cash flows
and prospects.

We believe that climate change has the potential to negatively affect our business. We are exposed to physical risks (such as extreme weather conditions),
risks in transitioning to a low-carbon economy (such as additional legal or regulatory requirements, changes in technology, market risk and reputational
risk) and social and human effects (such as population dislocations and harm to health and well-being) associated with climate change. These risks can be
either acute (short-term) or chronic (long-term).

The adverse impacts of climate change include increased frequency and severity of natural disasters and extreme weather events. Extreme weather poses
physical  risks  to  our  facilities  as  well  as  those  of  our  suppliers,  such  as  physical  damage  to  facilities,  loss  or  spoilage  of  inventory,  and  business
interruption.  Other  potential  physical  impacts  due  to  climate  change  include  reduced  access  to  high-quality  water  in  certain  regions  and  the  loss  of
biodiversity, which could impact future product development. These risks could disrupt our operations and supply chains, which may result in increased
costs.

New  legal  or  regulatory  requirements  may  be  enacted  to  prevent,  mitigate,  or  adapt  to  the  implications  of  a  changing  climate  and  its  effects  on  the
environment. These regulations could result in us being subject to new or expanded carbon pricing or taxes, increased compliance costs, restrictions on
greenhouse gas emissions, investment in new technologies, increased carbon disclosure and transparency, upgrade of facilities to meet new building codes,
and the redesign of utility systems, which could increase our operating costs. Our supply chain would likely be subject to these same transitional risks and
would likely pass along any increased costs to us.

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.

66

If we fail to establish and maintain proper and effective internal control over financial reporting, our operating results and our ability to operate our
business could be harmed.

Adequate internal control over financial reporting is necessary for us to provide reliable financial reports and, together with effective disclosure controls
and procedures, are designed to prevent or detect material misstatements due to fraud or error. Any failure to implement required new or improved controls,
or  difficulties  encountered  in  their  implementation  could  cause  us  to  fail  to  meet  our  reporting  obligations.  In  addition,  any  testing  conducted  by  us  in
connection  with  Section  404  of  the  Sarbanes-Oxley  Act,  or  any  subsequent  testing  by  our  independent  registered  public  accounting  firm,  may  reveal
deficiencies  in  our  internal  control  over  financial  reporting  that  are  deemed  to  be  material  weaknesses  or  that  may  require  prospective  or  retroactive
changes to our financial statements or identify other areas for further attention or improvement. Inadequate internal controls could also cause investors to
lose confidence in our reported financial information, which could have a negative effect on the trading price of our stock and make it more difficult for us
to effectively market and sell our service to new and existing customers.

Implementing  any  appropriate  changes  to  our  internal  controls  may  distract  our  officers  and  employees,  entail  substantial  costs  to  modify  our  existing
processes, and take significant time to complete. These changes may not, however, be effective in maintaining the adequacy of our internal controls, and
any failure to maintain that adequacy, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs
and harm our business.

We  have  a  hybrid  in-person  and  remote  workforce,  which  could  subject  us  to  certain  operational  challenges  and  risks  and  potential  harm  to  our
business.

We expect to continue to be subject to the challenges and risks of having a remote workforce, as well as challenges and risks from operating with a hybrid
workforce.  For  example,  certain  security  systems  in  remote  workplaces  may  be  less  secure  than  those  used  in  our  offices,  which  may  subject  us  to
increased security risks and expose us to risks of data or financial loss and associated disruptions to our business operations. Members of our workforce
who work remotely may not have access to technology that is as robust as that in our offices, so the networks, information systems, applications, and other
tools available to those remote workers to be more limited or less reliable than in our offices. We may also be exposed to risks associated with the locations
of remote workers, including compliance with local laws and regulations or exposure to compromised internet infrastructure. Allowing members of our
workforce to work remotely may create intellectual property risk if employees create intellectual property on our behalf while residing in a jurisdiction with
unenforced  or  uncertain  intellectual  property  laws.  Our  hybrid  work  model  may  also  subject  us  to  other  operational  challenges  and  risks.  For  example,
hybrid working may adversely affect our ability to recruit and retain personnel who prefer a fully remote or fully in-person work environment. Operating
our business with both remote and in-person workers, or workers who work in flexible locations and on flexible schedules, could have a negative impact on
our corporate culture, decrease the ability of our workforce to collaborate and communicate effectively, or decrease innovation and productivity. If we are
unable to manage these challenges, our business could be harmed or otherwise negatively impacted.

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  and  our  clinical  trial  sites  personnel,  to  conduct  or  otherwise  support  clinical  trials  for  COSELA.  We  rely  heavily  on  these
parties for performance of clinical trials for our product. Nevertheless, we are and will continue to 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.

67

We, our investigators, our clinical trial sites and our CROs are 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 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,  our  clinical  sites  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, our clinical trial sites
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.

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.

68

We contract with third parties for the manufacture of COSELA for nonclinical 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 nonclinical 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 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 outside of contractual obligations and periodic independent audits of their quality systems. 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.

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.

69

The third parties upon which we rely for the supply of the drug substance and drug product 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 our drug 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 product 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  product.  Establishing  additional  or
replacement suppliers for drug substances and drug 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, 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 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.

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.

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 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.

70

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, maintain, and enforce 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, maintain, and enforce 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 and its uses, pharmaceutical formulations and dosages, and processes for the manufacture of it. 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.

71

We currently solely own or exclusively license our patents and 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.  Recent  United  States  Supreme  Court  and  Federal  Circuit  rulings  have  narrowed  the
scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. For example, recent Federal
Circuit rulings such as Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1340 (Fed. Cir. 2010) (en banc), Wyeth & Cordis Corp. v. Abbott Labs, 720
F.3d 1380 (Fed. Cir. 2013), Enzo Life Scis., Inc. v. Roche Molecular Sys., 928 F.3d 1340 (Fed. Cir. 2019), and Idenix Pharms. LLC v. Gilead Scis. Inc., 941
F.3d  1149  (Fed.  Cir.  2019),  and  Amgen  Inc.  v.  Sanofi,  598  U.S.  594  (2023)  have  significantly  heightened  the  standard  for  securing  broad  claims  to
pharmaceutical and biological products. In addition, recent Federal Circuit rulings such as In re Cellect, 81 F.4th 1216 (Fed. Cir. 2023) have expanded the
bases for invalidating a patent under the judicially created doctrine of obviousness-type double patenting. 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.

The  recently-passed  Inflation  Reduction  Act  may  impact  our  future  strategies  and  results  of  operations  as  it  pertains  to  COSELA.  Passed  by  the  117th
United States Congress and signed into law by President Joe Biden on August 16, 2022, the Inflation Reduction Act of 2022 is landmark legislation which
may significantly impact the pharmaceutical industry.

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.

72

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 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.

73

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 marketplace. 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 COSELA is a small molecule, after commercialization it 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 ("ANDA") to the FDA to obtain approval to sell our drug using
bioequivalence  data  only.  Under  the  Hatch  Waxman  Act,  we  have  listed  all  of  our  patents  that  cover  COSELA  and  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 trilaciclib has been deemed a new chemical entity. 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.

74

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  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.

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

Filing, prosecuting and defending patents on COSELA and lerociclib 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 ("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.

75

In  addition,  in  November  2015,  members  of  the  World  Trade  Organization  ("WTO"),  which  administers  TRIPS,  voted  to  extend  the  exemption  against
enforcing  pharmaceutical  drug  patents  in  least  developed  countries  until  2033.  We  currently  have  no  patents  or  pending  applications  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.

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.

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 ("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  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.

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  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.

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.

77

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 of our products or 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;
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.

78

Forecasting potential sales for COSELA is difficult, and if our projections are inaccurate, our business may be harmed and our stock price may be
adversely affected.

Our business planning requires us to forecast or make assumptions regarding product demand and revenues for COSELA, despite numerous uncertainties.
These uncertainties may be increased if we rely on third parties to conduct commercial activities in certain jurisdictions and provide us with accurate and
timely information. Actual results may differ materially from projected results for various reasons, including the following, as well as risks identified in
other risk factors:

•
•

•
•
•
•
•
•

•

the efficacy and safety of COSELA, including as relative to marketed products and drug candidates in development by third parties;
pricing (including discounting and other promotions), reimbursement, product returns or recalls, competition, labeling, adverse
events and other items that impact commercialization;
the rate of adoption in the particular market, including fluctuations in demand for various reasons;
potential market size;
lack of patient and physician familiarity with the drug product;
lack of patient use and physician prescribing history;
lack of commercialization experience with COSELA;
uncertainty relating to when COSELA may become commercially available to patients in a particular jurisdiction and rate of
adoption; and
products provided without compensation through patient support programs or product sample programs, may not eventually result in
or contribute to revenue-producing prescriptions.

We  expect  that  our  revenues  from  sales  of  COSELA  will  be  based  in  part  on  estimates,  judgment  and  accounting  policies.  Any  incorrect  estimates  or
disagreements with regulators or others regarding such estimates, judgment or accounting policies may result in changes to our guidance, projections or
previously reported results. Expected and actual product sales and quarterly and other results may greatly fluctuate, including in the near-term, and such
fluctuations can adversely affect the price of our common stock, perceptions of our ability to forecast demand and revenues, and our ability to maintain and
fund  our  operations.  The  metrics  that  we  are  tracking  in  order  to  evaluate  the  success  of  our  sales  efforts  may  not  correlate  to  commercial  success,
particularly given the challenging market for COSELA.

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.

79

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.

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 1C. Cybersecurity.

We recognize the critical importance of maintaining the trust and confidence of customers, patients, business partners and employees toward our business
and  are  committed  to  protecting  the  confidentiality,  integrity  and  availability  of  our  business  operations  and  systems.  Our  board  of  directors  is  actively
involved in oversight of our risk management activities, and cybersecurity represents an important element of our overall approach to risk management.
Our cybersecurity policies, standards, processes and practices are based on recognized frameworks established by the National Institute of Standards and
Technology ("NIST") and other applicable industry standards. In general, we seek to address cybersecurity risks through a comprehensive, cross-functional
approach that is focused on preserving the confidentiality, security and availability of the information that we collect and store by identifying, preventing
and mitigating cybersecurity threats and effectively responding to cybersecurity incidents when they occur.

Cybersecurity Risk Management and Strategy; Effect of Risk

We face risks related to cybersecurity such as unauthorized access, cybersecurity attacks and other security incidents, including as perpetrated by hackers
and unintentional damage or disruption to hardware and software systems, loss of data, and misappropriation of confidential information. To identify and
assess material risks from cybersecurity threats, we maintain a comprehensive cybersecurity program to ensure our systems are effective and prepared for
information security risks, including regular oversight of our programs for security monitoring for internal and external threats to ensure the confidentiality
and integrity of our information assets. We consider risks from cybersecurity threats alongside other company risks as part of our overall risk assessment
process.  We  employ  a  range  of  tools  and  services,  including  regular  network  and  endpoint  monitoring,  audits,  vulnerability  assessments,  penetration
testing,  threat  modeling  and  tabletop  exercises  to  inform  our  risk  identification  and  assessment.  As  discussed  in  more  detail  under  “Cybersecurity
Governance” below, our board of directors provides oversight of our cybersecurity risk management and strategy processes, which are led by our General
Counsel and Chief Compliance Officer, Vice President, Information Technology and Associate Director of Information Technology Operations, and Chief
Operations Officer.

We also identify our cybersecurity threat risks by comparing our processes to standards set by NIST, as well as by engaging experts to attempt to infiltrate
our  information  systems.  To  provide  for  the  availability  of  critical  data  and  systems,  maintain  regulatory  compliance,  manage  our  material  risks  from
cybersecurity threats, and protect against and respond to cybersecurity incidents, we undertake the following activities:

•
•

•

•

•

•

•

•

monitor emerging data protection laws and implement changes to our processes that are designed to comply with such laws;
through our policies, practices and contracts (as applicable), require employees, as well as third parties that provide services on our
behalf, to treat confidential information and data with care;
employ  technical  safeguards  that  are  designed  to  protect  our  information  systems  from  cybersecurity  threats,  including  firewalls,
intrusion  prevention  and  detection  systems,  anti-malware  functionality  and  access  controls,  which  are  evaluated  and  improved
through vulnerability assessments and cybersecurity threat intelligence;
provide regular, mandatory training for our employees and contractors regarding cybersecurity threats as a means to equip them with
effective tools to address cybersecurity threats, and to communicate our evolving information security policies, standards, processes
and practices;
conduct regular phishing email simulations for all employees and contractors with access to our email systems to enhance awareness
and responsiveness to possible threats;
conduct at least annual cybersecurity management and incident training for employees involved in our systems and processes that
handle sensitive data;
conduct annual tabletop exercises facilitated by a third party to simulate a response to a cybersecurity incident and use the findings to
improve our processes and technologies;
review and revise our incident response plan at least annually to ensure that it is current with respect to our technology and current
risks;

81

•

•
•

•

leverage the NIST incident handling framework to help us identify, protect, detect, respond and recover when there is an actual or
potential cybersecurity incident;
carry information security risk insurance that provides protection against the potential losses arising from a cybersecurity incident;
review  privileged  network  and  application  accounts  every  three  (3)  months  for  appropriate  access  privileges,  and  review  user
accounts every six (6) months; and
review  and  test  our  disaster  recovery  plan  annually  to  confirm  effective  and  efficient  recovery  processes  are  in  place  to  support
business continuity in the event of a disaster.

Our incident response plan coordinates the activities we take to prepare for, detect, respond to and recover from cybersecurity incidents, which include
processes  to  triage,  assess  severity  for,  escalate,  contain,  investigate  and  remediate  the  incident,  as  well  as  to  comply  with  potentially  applicable  legal
obligations and mitigate damage to our business and reputation.

As part of the above processes, we regularly engage with consultants and other third party advisors, including annually having a third-party review our
cybersecurity program to help identify areas for continued focus, improvement and compliance.

Our processes also address cybersecurity threat risks associated with our use of third-party service providers, including our suppliers and manufacturers or
who have access to patient and employee data or our systems. In addition, cybersecurity considerations affect the selection and oversight of our third-party
service providers. We perform diligence on third parties that have access to our systems, data or facilities that house such systems or data, and continually
monitor cybersecurity threat risks identified through such diligence. When we identify a vendor who may pose a cybersecurity threat risk, we will require
those third parties to agree by contract to manage their cybersecurity risks in specified ways, and to agree to be subject to cybersecurity audits.

We  describe  whether  and  how  risks  from  identified  cybersecurity  threats,  including  as  a  result  of  any  previous  cybersecurity  incidents,  have  materially
affected or are reasonably likely to materially affect us, including our business strategy, results of operations, or financial condition, under the heading "Our
business and operations could suffer in the event of system failures, cyberattacks, or deficiency in our cyber security," which disclosures are incorporated
by reference herein.

In  the  last  three  fiscal  years,  we  have  not  experienced  any  material  cybersecurity  incidents.  We  did  not  incur  any  expenses  related  to  penalties  and
settlements.

Cybersecurity Governance; Management

Cybersecurity is an important part of our risk management processes and an area of focus for our board of directors and management. In general, our board
of directors oversees risk management activities designed and implemented by our management, and considers specific risks, including, for example, risks
associated  with  our  strategic  plan,  business  operations,  and  capital  structure.  Our  board  of  directors  executes  its  oversight  responsibility  for  risk
management both directly and through delegating oversight of certain of these risks, including those from cybersecurity threats, to its audit committee.

On  an  annual  basis,  our  board  of  directors  receives  an  update  from  management  of  our  cybersecurity  threat  risk  management  and  strategy  processes
covering  topics  such  as  data  security  posture,  results  from  third-party  assessments,  progress  towards  pre-determined  risk-mitigation-related  goals,  our
incident response plan, and material cybersecurity threat risks or incidents and developments, as well as the steps management has taken to respond to such
risks. In such sessions, our board of directors generally receives materials that include a cybersecurity scorecard and other materials discussing current and
emerging  material  cybersecurity  threat  risks,  and  describing  our  ability  to  mitigate  those  risks,  as  well  as  recent  developments,  evolving  standards,
technological developments and information security considerations arising with respect to our peers and third parties, and discusses such matters with our
Vice President, Information Technology. Our board of directors also receive prompt and timely information regarding any cybersecurity incident that meets
establishing reporting thresholds, as well as ongoing updates regarding any such incident until it has been addressed.

Members of our board of directors may also engage in conversations with management on cybersecurity-related news events and discuss any updates to our
cybersecurity risk management and strategy programs.

82

Our  cybersecurity  risk  management  and  strategy  processes,  which  are  discussed  in  greater  detail  above,  are  led  by  our  Vice  President,  Information
Technology,  Associate  Director  of  Information  Technology  Operations,  General  Counsel  and  Chief  Compliance  Officer,  and  Chief  Operations  Officer.
Such  individuals  have  collectively  over  30  years  of  prior  work  experience  in  various  roles  involving  managing  information  security,  developing
cybersecurity  strategy,  implementing  effective  information  and  cybersecurity  programs,  as  well  as  several  relevant  degrees.  These  management  team
members are informed about and monitor the prevention, mitigation, detection, and remediation of cybersecurity incidents through their management of,
and participation in, the cybersecurity risk management and strategy processes described above, including the operation of our incident response plan. As
discussed  above,  our  Vice  President  of  Information  Technology  and  Associate  Director  of  Information  Technology  Operations  report  to  our  board  of
directors about cybersecurity threat risks, among other cybersecurity related matters, on an annual basis.

Item 2. Properties.

Our corporate headquarters is located at 700 Park Offices Drive in Research Triangle Park, North Carolina ("700 Building"), 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. On November 1, 2023, we entered into a sublease agreement with a third party for the third floor of the 700 Building, the term of which commences
on January 1, 2024 and expires on August 31, 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.

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 $46.3 million, $31.3 million, and $11.1 million of net product sales from COSELA for the
years ended December 31, 2023, 2022, and 2021, respectively. We recorded $36.2 million, $20.0 million, and $20.4 million of license revenue for the years
ended December 31, 2023, 2022, and 2021, respectively. To date, we have financed our operations primarily through the sale of equity securities, our loan
agreement with Hercules, 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, 2023, we had cash and cash equivalents of $32.2 million and marketable securities of $49.9 million. Since inception we have incurred
net losses. As of December 31, 2023, we had an accumulated deficit of $780.0 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  to  continue  to  incur  significant  expenses  and  increasing  operating  losses.  As  disclosed  in  the  Liquidity  and
Capital Resources section, as of the date of issuance of these financial statements, we expect that our cash and cash equivalents and marketable securities as
of December 31, 2023 will be sufficient to fund our planned operations and remain in compliance with our objective financial covenants for at least the
next 12 months from the date of issuance of these financial statements. To date, inflation has not had a material impact on our business, but if the global
inflationary trends continue, we expect appreciable increases in clinical trial, selling, labor, and other operating costs. If our costs were to become subject to
significant inflationary pressures, we may not be able to fully offset such higher costs through price increases of our product. Our inability or failure to do
so could adversely affect our business, financial condition and results of operations.

In  addition,  currently  there  is  a  conflict  involving  Russia  and  Ukraine  and  a  conflict  involving  Israel  and  Hamas,  and  these  conflicts  may  directly  or
indirectly impact our contract research organizations, clinical data management organizations, and clinical investigators’ ability to conduct certain of our
trials in Eastern European countries, and may increase our product development costs and materially harm our business.

85

We  also  expect  to  continue  incurring  costs  for  research  and  development,  commercial  activities,  and  selling,  general  and  administrative  expenses,  in
connection with our ongoing and future initiatives as we:

•
•
•

•
•
•
•
•

continue development of trilaciclib, including continuation of ongoing clinical trials;
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 in the medical community and with third-party payors;
maintain, expand and protect our intellectual property portfolio;
enter into collaboration arrangements, if any, for the development of our product or in-license other products and technologies;
add 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 have been derived from our license agreements.

Pursuant to the exclusive license agreement with Simcere, during the twelve months ended December 31, 2023, we recognized $2.9 million in supply and
manufacturing  services,  $0.6  million  in  royalty  revenue,  and  $0.7  million  in  patent  and  clinical  trial  reimbursable  costs.  We  did  not  receive  any
development  milestones  during  the  twelve  months  ended  December  31,  2023.  On  April  28,  2023,  we  amended  the  license  agreement  with  Simcere,
whereby we received a one-time, non-refundable payment of $30.0 million in exchange for the relief of future royalty payments from the sale of COSELA
in  Greater  China,  which  was  recognized  as  license  revenue  during  the  period.  See  "Business  -  License  Agreements  -  Exclusive  license  to  Simcere  for
trilaciclib in Greater China" section of this Annual Report for more details.

Pursuant to the exclusive license agreement with EQRx, during the twelve months ended December 31, 2023, we recognized revenue of $1.7 million for
the reimbursement of EQRx patent and clinical trial costs, including $1.4 million of the $1.6 million payment received during the third quarter of 2023
following notice from EQRx of termination of the license agreement. As of December 31, 2023, the remaining $0.2 million is held as short-term deferred
revenue  on  the  balance  sheet  and  will  be  recognized  as  revenue  as  clinical  trial  costs  associated  with  the  wind  down  are  incurred.  No  milestones  were
previously achieved through the date of termination of the lerociclib license agreement, and as a result of the termination, we will not receive any further
milestone payments or future royalties from EQRx. See "Business - License Agreements - Exclusive license to EQRx for lerociclib" section of this Annual
Report for more details.

Pursuant  to  the  exclusive  license  agreement  with  Genor,  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. We did
not receive any development milestones during the twelve months ended December 31, 2023. See "Business - License Agreements - Exclusive license to
Genor for lerociclib" section of this Annual Report for more details.

Pursuant to the exclusive license agreement with Incyclix, we are entitled to receive an additional milestone payment and sales-based royalties, and have
right of first negotiation to re-acquire these assets. We did not receive the development milestone payment during the twelve months ended December 31,
2023. See "Business - License Agreements - Exclusive license to Incyclix" section of this Annual Report for more details.

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. In addition, costs to sell and
market COSELA are included within selling, general and administrative expense categories.

86

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 for excess and obsolete inventory.

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;
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 product for preclinical studies and clinical trials;
fees paid to consultants and other third parties who support our product development; and
allocated facility-related costs and overhead.

The successful development of our products is 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.  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 our 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;
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.

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, 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 continue to expand our research and development and commercialization of COSELA.

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.

87

Income taxes

To date, we have not been required to pay U.S. federal or state income due to our significant net operating losses. Income tax expense was recognized in
2023, 2022, and 2021 related to the foreign withholding taxes incurred as a result of the payments received under the Simcere license agreement during
each year.

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,
adjust the measure of progress and related revenue recognition.

88

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
evaluate each milestone to determine when and how much of the milestone to include in the transaction price. We first estimate the amount of the milestone
payment that we could receive using either the expected value or the most likely amount approach. We primarily use the most likely amount approach as
that approach is generally most predictive for milestone payments with a binary outcome. Then, we consider 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. For regulatory
milestones,  we  recognize  revenue  at  a  point  in  time  upon  approval,  as  that  is  when  achievement  of  the  milestone  is  considered  probable.  We  assess
milestones as they are achieved to determine whether they are tied to any other performance obligations in the respective license agreements.

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). During the twelve months ended December 31,
2023, the Company recognized $0.6 million in revenue related to sales-based royalties under the Simcere license agreement prior to the amendment on
April 28, 2023.

Product Sales, Net

We  sell  COSELA  to  specialty  distributors  in  the  U.S.  and,  in  accordance  with  ASC  606,  recognize  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,  (e)  GPO  fees,  and  (f)  other  discounts.  Where  appropriate,  these
estimates take into consideration a range of possible outcomes 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,  returns,  and  GPO  fees  are  classified  as  “Accrued  Expenses”  in  the  Balance  Sheets.  Discounts  such  as
chargebacks  and  specialty  distributor  fees  are  recorded  as  a  reduction  to  trade  accounts  receivable,  which  is  included  in  “Accounts  Receivable”  in  the
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.

89

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 offer 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 for excess and obsolete inventory.

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.

Debt

The Company classifies its loan payable in current or long-term liabilities based on the timing of scheduled principal payments. The Loan Agreement with
Hercules contains events of default, including a material adverse change, which is subjectively defined, in the Company’s business, payment defaults, and
breaches  of  covenants  following  any  applicable  cure  period.  In  the  event  of  default  by  the  Company  under  the  Loan  Agreement,  the  Company  may  be
required to repay all amounts then outstanding under the Loan Agreement. The Company has determined that subjective acceleration under the material
adverse events clause included in the Loan Agreement is not probable and, therefore, has classified the outstanding principal amount in long-term liabilities
based on the timing of scheduled principal payments.

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.

90

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 $14.5 million, $20.6 million and $22.3 million for the twelve months ended December 31,
2023, 2022 and 2021, 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:

•

•
•

•

•

the  expected  stock  price  volatility  assumptions  for  our  stock  options  were  determined  by  examining  the  historical  volatilities  for
industry  peers,  as  we  did  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  continued  to  use  the
guideline peer group volatility information until April 2023, when the historical volatility of our common stock became 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 9 – 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 twelve months ended December 31, 2023, 2022 and 2021.

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.

91

At December 31, 2023, we have federal net operating loss carryforwards (“NOLs”) of approximately $550.7 million, which are available to offset future
taxable income. Of the $550.7 million available, $93.5 million will begin to expire in 2029. The remaining $457.2 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 $401.2 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, 2023, we also had federal research and development (R&D) credit carryforwards of approximately $23.4 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% 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  was  $46.3  million  and  $31.3  million  for  the  twelve  months  ended  December  31,  2023  and  2022,  respectively.  The  increase  of
$15.0 million, or 48%, was primarily due to increased sales volume as we continued our commercialization efforts.

License revenue

License revenue was $36.2 million and $20.0 million for the twelve months ended December 31, 2023 and 2022, respectively. License revenue increased
$16.2 million, or 81%. License revenue recognized in the current year was primarily related to $30.0 million in revenue from the one-time payment for the
relief of future royalty payments, $2.9 million in supply and manufacturing services, and $0.6 million in royalty revenue from Simcere. Additionally, we
recognized $2.5 million in license revenue related to patent and clinical trial costs reimbursed by EQRx and Simcere.

Cost of goods sold

Cost of goods sold was $7.2 million and $3.7 million for the twelve months ended December 31, 2023 and 2022, respectively. The increase of $3.5 million,
or 95%, was primarily due to an increase in inventory write-offs and an increase in units sold.

Research and development

Research  and  development  expenses  were  $43.7  million  for  the  twelve  months  ended  December  31,  2023  as  compared  to  $83.3  million  for  the  twelve
months ended December 31, 2022. The decrease of $39.6 million, or 48%, was primarily due to a decrease of $37.3 million in our clinical program costs, a
decrease  of  $2.0  million  for  manufacturing  of  active  pharmaceutical  ingredients  and  drug  product  to  support  our  clinical  trials,  and  a  decrease  of  $0.3
million in pre-clinical and discovery costs. The following table summarizes our research and development expenses allocated to trilaciclib, lerociclib, and
unallocated research and development expenses for the periods indicated:

twelve months ended December 31, 2022. The decrease of $29.3 million, or 29%, was due to decreases of $14.6 million in commercialization activities,
$10.1 million in personnel costs due to a reduction in force, $1.1 million in professional fees, $2.4 million in medical affairs costs related to trilaciclib, and
$1.1 million in audit, IT, legal, office and other administrative expenses.

Total other income (expense), net

Total other income (expense), net was $(5.3) million for the twelve months ended December 31, 2023 as compared to $(9.7) million for twelve months
ended December 31, 2022. The change of $4.4 million, or 45%, was primarily driven by an increase of $1.7 million in interest income, an increase of $2.2
million  in  other  income,  and  a  decrease  of  $0.4  million  in  interest  expense  on  the  loan  payable  due  to  reduction  of  principal  outstanding  following  the
principal repayment in the second quarter of 2023.

December 31, 2022. The increase of $1.4 million, or 82%, was primarily driven by the foreign tax withheld on the one-time payment for the relief of future
royalty payments received from Simcere during the first half of 2023.

$20.2  million,  or  182%,  was  primarily  due  to  increased  sales  volume  as  we  continued  our  commercialization  efforts.  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  $20.0  million  and  $20.4  million  for  the  years  ended  December  31,  2022  and  December  31,  2021,  respectively.  License  revenue
decreased $0.4 million, or 2% License revenue recognized in the current year was primarily related to $14.0 million in milestone payments from Simcere.
We also recognized $2.4 million and $2.3 million in clinical trial costs reimbursed by EQRx and Simcere, respectively. Additionally, we recognized $1.3
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 $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.

Cost of goods sold

Cost  of  goods  sold  was  $3.7  million  and  $2.0  million  for  the  years  ended  December  31,  2022  and  December  31,  2021,  respectively.  The  increase  of
$1.7 million, or 85%, was primarily due to an increase in units sold and an increase in overhead.

Research and development

Research  and  development  expenses  were  $83.3  million  for  the  year  ended  December  31,  2022  as  compared  to  $76.2  million  for  the  year  ended
December  31,  2021.  The  increase  of  $7.1  million,  or  9%,  was  primarily  due  to  an  increase  of  $10.8  million  in  our  clinical  program  costs,  offset  by  a
decrease of $3.2 million for manufacturing of active pharmaceutical ingredient and drug product to support our clinical trials and a decrease of $0.5 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, 2021. The increase of $4.7 million, or 5% was due to an increase of $12.5 million in personnel related costs due to increased headcount, and
an increase of $2.6 million in office and other administrative expenses, of which $1.7 million related to travel expenses. These increases were offset by a
decrease of $7.3 million in commercialization activities, a decrease of $1.7 million in information technology systems and related expenses, and a decrease
of $1.4 million in medical affairs costs related to trilaciclib, professional services, and taxes.

Total other income (expense), net

Total other income (expense), net was $(9.7) million for the year ended December 31, 2022 as compared to $(5.0) million for the year ended December 31,
2021. The change of $4.7 million, or 94%, was primarily driven by an increase in interest expense on loan payable due to higher principal balance in 2022
as compared to 2021.

Income tax expense

Income  tax  expense  was  $1.7  million  for  the  year  ended  December  31,  2022  as  compared  to  $0.9  million  for  the  year  ended December  31,  2021.  The
increase of $0.8 million, or 89%, in foreign tax withholdings incurred is a result of an increase in license revenue recognized from Simcere as compared to
the prior year.

Liquidity and Capital Resources

We have experienced net losses since our inception, and have an accumulated deficit of $780.0 million and $732.0 million as of December 31, 2023 and
December  31,  2022,  respectively.  We  expect  to  incur  losses  and  have  negative  net  cash  flows  from  operating  activities  as  we  execute  on  our  strategy
including engaging in further research and development activities, particularly conducting non-clinical studies and clinical trials. Our success depends on
the  ability  to  successfully  commercialize  our  technologies  to  support  our  operations  and  strategic  plan.  As  of  the  date  of  issuance  of  these  financial
statements,  we  expect  that  our  cash  and  cash  equivalents  and  marketable  securities  as  of  December  31,  2023  will  be  sufficient  to  fund  our  planned
operations and remain in compliance with our objective financial covenants for at least the next 12 months from the date of issuance of these financial
statements. 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.
There  can  be  no  assurances  that  we  will  be  able  to  secure  such  additional  financing  if  at  all,  or  on  terms  that  are  satisfactory  to  us,  and  that  it  will  be
sufficient to meet our needs. In the event we are not successful in obtaining sufficient funding, this could force us to delay, limit, or reduce our product
development,  commercialization  efforts  or  other  operations.  Our  financial  statements  have  been  prepared  assuming  that  we  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.  The  financial
statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of
liabilities  that  might  result  from  the  outcome  of  the  uncertainties  described  above.  In  connection  with  the  Loan  Payable  described  in  Note  7,  we  are
required to remain in compliance with a minimum cash covenant and are subject to a conditional borrowing base measured on a trailing three-month net
revenue basis, which begins with the financial reporting for the period ending June 30, 2023, and has been tested monthly thereafter. The lender also has
the ability to call debt based on a material adverse change clause, which is subjectively defined. As of December 31, 2023, we are in compliance with the
minimum cash covenant and the conditional borrowing base requirements. If we do not maintain unrestricted cash equal to at least 35% of the outstanding
or do not comply with the conditional borrowing base requirements or the subjective acceleration clauses are triggered under the agreement, then the lender
may call the debt, resulting in us immediately needing additional funds.

To date, we have funded our operations primarily through proceeds from our initial public offering, our follow-on stock offerings, our Loan Agreement
with  Hercules,  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 (the “2021 Form S-3”) with the Securities and Exchange Commission (the
“SEC”). 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.

At the time of the filing of our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 23, 2022, we no longer
qualified as a “well-known seasoned issuer” as such term is defined in Rule 405 under the Securities Act. As a result, in February 2022, we amended the
2021 Form S-3 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. The 2021 Form S-3, as amended, will remain in effect for up to three years from
the date it originally became effective, which was July 2, 2021.

At-the-market offerings

In  connection  with  the  2021  Form  S-3,  as  amended,  we  entered  into  a  sales  agreement  for  “at  the  market  offerings”  with  Cowen  and  Company,  LLC
(“Cowen”) acting as our agent (the “2022 Sales Agreement”), which allows us to issue and sell shares of common stock pursuant to the amended 2021
Form S-3 for total gross sales proceeds of up to $100.0 million from time to time through Cowen.

As of the date hereof, we have not sold any shares of common stock or other securities under the 2022 Sales Agreement.

Loan and Security Agreement

On  May  29,  2020,  we  entered  into  the  Loan  Agreement,  under  which  they  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 was approximately 48 months, with a maturity
date of June 1, 2024. No principal payments were due during an interest-only period, commencing on the initial borrowing date and continuing through
June  1,  2022.  The  interest  only  period  could  be  extended  through  January  1,  2023  upon  satisfaction  of  certain  milestones.  Following  the  interest  only
period, we agreed to repay the principal balance and interest of the advances in equal monthly installments through June 1, 2024.

On March 31, 2021, we entered into a First Amendment to Loan and Security Agreement (the “First Amendment”) with Hercules whereby we 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 (the “Second Amendment”) with Hercules, under which
Hercules 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  the  first  tranche.  We  had  the  right  to
request that Hercules make the remaining $25.0 million term loan advances under the first tranche to us by September 15, 2022, which we did not exercise.
No principal payments were 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  agreed  to  repay  the  principal  balance  and  interest  of  the  advances  in  equal  monthly  installments
through the maturity date of November 1, 2026.

On June 24, 2022, we entered into a Third Amendment to Loan and Security Agreement (the “Third Amendment”) with Hercules which extended the time
for drawing the remainder of the first tranche advance of up to $25.0 million from September 15, 2022 to December 31, 2022, which we did not exercise.
The Third Amendment also added a minimum cash covenant whereby we must maintain unrestricted cash equal to at least 50% of the outstanding debt,
and such percentage shall decrease upon us achieving specified net product revenue of COSELA. It further provides for a minimum revenue covenant that,
beginning August 15, 2022, with the reporting of the financial results for the second fiscal quarter ended June 30, 2022, and tested monthly, we must have
achieved net product revenue of COSELA of at least 80% of the amounts projected in our forecast. Testing of the minimum revenue covenant shall be
waived at any time in which either (a) our market capitalization exceeds $750.0 million and we maintain unrestricted cash equal to at least 50% of the total
amounts funded, or (b) we maintain unrestricted cash equal to at least 100% of the total amounts funded.

On  November  1,  2022,  we  entered  into  a  Fourth  Amendment  to  Loan  and  Security  Agreement  (the  “Fourth  Amendment”)  with  Hercules.  The  Fourth
Amendment extended the time for drawing the Tranche 1D Advance (as defined in the Loan Agreement) of up to $25.0 million from December 31, 2022 to
June 30, 2023. The Fourth Amendment continues to provide for a minimum revenue covenant, tested monthly, where we must achieve net product revenue
of COSELA of at least 80% of the amounts projected in our forecast. The Fourth Amendment also amended the minimum cash covenant such that if the
outstanding  debt  is  less  than  or  equal  to  $75.0  million,  we  must  maintain  unrestricted  cash  equal  to  at  least  65%  of  the  outstanding  debt  in  addition  to
meeting the required revenue covenant. In addition, if the outstanding debt is greater than $75.0 million, we must maintain unrestricted cash equal to at
least  70%  of  the  outstanding  debt  while  meeting  the  revenue  covenant.  If  we  achieve  the  specified  net  revenue  of  COSELA,  the  cash  percentage  will
decrease to 45% of the outstanding debt. Testing of the minimum revenue covenant shall be waived at any time in which either (a) our market capitalization
exceeds $750.0 million and we maintain unrestricted cash equal to at least 50% of the total amounts funded, or (b) we maintain unrestricted cash equal to at
least 100% of the total amounts funded. The Fourth Amendment also re-set the prepayment premiums associated with any prepayment of the loans under
the Loan Agreement.

97

On  June  6,  2023,  we  entered  into  a  Fifth  Amendment  to  Loan  and  Security  Agreement  (the  “Fifth  Amendment”)  with  Hercules,  under  which  Hercules
agreed to lend us up to $75.0 million, subject to specified conditions. In conjunction with the closing of the Fifth Amendment, we repaid $25.0 million of
the outstanding debt such that the total loan amount outstanding upon closing of the Fifth Amendment was $50.0 million. The Fifth Amendment eliminated
advances  under  Tranches  2  and  3  and  increased  the  advance  available  under  Tranche  4  from  $15.0  million  to  $25.0  million  and  extended  the  time  for
drawing  the  Tranche  4  Advance  (as  defined  in  the  Loan  and  Security  Agreement)  from  June  30,  2024  to  December  15,  2024.  The  Fifth  Amendment
adjusted the minimum cash covenant such that we must maintain unrestricted cash equal to at least 35% of the outstanding debt at all times. The Fifth
Amendment removed the existing minimum revenue covenant and provided for a conditional borrowing base limit such that, beginning with the financial
reporting  for  the  period  ended  June  30,  2023,  and  tested  monthly,  our  debt  outstanding  shall  not  exceed  certain  thresholds  of  trailing  three  months  net
product revenue of COSELA.

Hercules also has the ability to call debt based on a material adverse change clause, which is subjectively defined. If we are not in compliance with the
minimum cash covenant, conditional borrowing base requirements, or the subjective acceleration clauses are triggered under the agreement, then Hercules
may call the debt resulting in us immediately needing additional funds. We have determined that subjective acceleration under the material adverse events
clause included in the Loan Agreement is not probable and, therefore, have classified the outstanding principal amount in long-term liabilities based on the
timing of scheduled principal payments. As of December 31, 2023, and as of the date of the issuance of these financial statements, we were not in default
under the Loan Agreement as we remained in compliance with the minimum cash covenant, the conditional borrowing base requirements, and have not
been notified of an event of default by the lender under the Loan Agreement.

License Agreements

On May 22, 2020, we entered into a global license agreement with Incyclix, formerly ARC Therapeutics, LLC, for the development and commercialization
of a CDK2 inhibitor for all human and veterinary uses. On June 15, 2020, we entered into an exclusive license agreement with Genor for the development
and  commercialization  of  lerociclib  in  the  Genor  Territory.  On  July  22,  2020,  we  entered  into  an  exclusive  license  agreement  with  EQRx  for  the
development and commercialization of lerociclib in the EQRx Territory. The license agreement with EQRx was terminated during the previous quarter. On
August 3, 2020, we entered into an exclusive license agreement with Simcere for the development and commercialization of trilaciclib in all indications in
the  Simcere  Territory.  The  license  agreement  with  Simcere  was  amended  on  April  28,  2023.  See  “Note  10  –  License  Revenue”  to  the  accompanying
audited  financial  statements  included  in  Item  15  of  this  Annual  Report  for  a  further  description  of  our  license  agreements  and  our  relationships  with
Incyclix, Genor, EQRx, and Simcere.

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 and marketable securities will be sufficient to fund our projected cash needs for at least the next 12
months from the date of issuance of the financial statements.

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;

99

•
•

•
•

•

•
•

•

•
•
•

•

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 agreements 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;
the extent to which we acquire or in-license product candidates and technologies 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;
the  potential  benefit  of  the  NMPA’s  conditional  approval  for  our  products  and  product  candidates  and  our  ability  to  provide
comprehensive clinical data from post-approval clinical research;
revenue received from commercial sales of our product candidates;
our ability to meet the required financial covenants under our loan agreement;
the  costs  of  preparing,  filing  and  prosecuting  patent  applications,  maintaining  and  enforcing  our  intellectual  property  rights  and
defending intellectual property-related claims; and
global economic uncertainty, rising inflation, rising interest rates, market disruptions and volatility in commodity prices.

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.
Other than amounts included under the terms of our licensing arrangements and the Loan Agreement with Hercules, which are subject to certain conditions,
we do not have any committed external source of funds. We may be bound by ongoing compliance with financial covenants under 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.

Represents  future  minimum  lease  payments  under  the  non-cancelable  lease  for  our  current  headquarters  in  Research  Triangle  Park,  NC.  The
lease for our current 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  five
years. The lease for our former headquarters expired in December 2022, no payments were owed or paid related to this lease subsequent to the
lease expiration date. 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 under our Fifth Amendment to the Loan and Security Agreement with Hercules with outstanding
borrowings of $50.0 million as of December 31, 2023. 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 14.15%, which was the interest rate in effect as of December 31, 2023. Additionally, the table above includes end of term charges of $2.1
million  due  on  June  1,  2025  and  $3.4  million  due  upon  maturity  on  November  1,  2026.  See  Note  7  of  the  financial  statements  for  further
discussion of the Hercules loan agreement.

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 cancellable at any time by us, generally upon 30-60 days
prior  written  notice.  As  of  December  31,  2023,  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.

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.

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 our own oncology sales team 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

For  a  discussion  of  recent  accounting  pronouncements,  refer  to  Note  2,  Basis  of  Presentation  and  Summary  of  Significant  Accounting  Policies,  to  our
financial statements appearing elsewhere in this Annual Report on Form 10-K.

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,  which  are  affected  by
changes  in  the  general  level  of  U.S.  interest  rates.  We  had  cash  and  cash  equivalents  of  $32.2  million  and  marketable  securities  of  $49.9  million  as  of
December  31,  2023.  Cash  and  cash  equivalents  consist  of  deposits  in  banks,  including  checking  accounts  and  money  market  accounts  and  funds.
Marketable securities consist of U.S. Treasury bills. Such interest-earning instruments carry a degree of interest rate risk; however, historical fluctuations in
interest income have not been significant. Due to the short-term nature of our cash equivalents, a sudden change in interest rates would not be expected to
have a material effect on our business, financial condition or results of operations.

101

We also have exposure to market risk on our Loan Agreement with Hercules. Our Loan Agreement (as such is amended from time to time) 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) 5.65%, and
(ii) 9.15%. As of December 31, 2023, $50.0 million of principal was outstanding under the Loan Agreement with Hercules. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources - Loan and Security Agreement" section of this Annual
Report for more details.

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 during the three and twelve months ended December 31, 2023.

Item 8. Financial Statements and Supplementary Data.

The financial statements of G1 Therapeutics, Inc. are provided in Part IV, Item 15 in this Annual Report.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

Not Applicable.

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  Exchange  Act  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,  2023,  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 Exchange Act). 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, 2023, 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 the fourth quarter of 2023 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, 2023.

102

Item 9B. Other Information.

amended), adopted, terminated or modified a Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement (as such terms are defined in Item
408 of Regulation S-K of the Securities Act of 1933, as amended).

Report of Independent Registered Public Accounting Firm

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

Opinion on the Financial Statements

We have audited the accompanying balance sheets of G1 Therapeutics, Inc. (the “Company”) as of December 31, 2023 and 2022, and the related statements
of operations, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes
(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position
of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2023 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial
statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  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 of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform
the  audit  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are
required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the
Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Emphasis of Matter

As discussed in Note 2 to the financial statements, the Company will require additional financing to fund future operations. Management’s evaluation of
the events and conditions and plans to mitigate this matter are also described in Note 2.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or
required  to  be  communicated  to  the  audit  committee  and  that  (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  5  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 $10.9 million as of December 31,
2023. 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.

F-1

The principal considerations for our determination that performing procedures relating to accrued external clinical study costs is a critical audit matter are
(i) the significant judgment by management in estimating the costs incurred to date, specifically progress towards completion of specific tasks, and (ii) 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, among others, (i) testing management’s process for estimating accrued external clinical study costs, (ii) evaluating
the  appropriateness  of  the  model  used  by  management  to  develop  the  estimate,  (iii)  evaluating  the  reasonableness  of  significant  assumptions  related  to
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 focused on the development and commercialization of novel
small molecule therapeutics for the treatment of patients with cancer. The Company's first product approved by the U.S. Food and Drug Administration
(“FDA”),  COSELA®  (trilaciclib),  is  the  first  and  only  therapy  indicated  to  proactively  help  protect  bone  marrow  from  the  damage  of  chemotherapy
(myeloprotection) is the first innovation in managing myeloprotection in decades. COSELA (trilaciclib hydrochloride for injection) is also conditionally
approved  by  the  China  National  Medical  Products  Administration  (NMPA)  for  marketing  in  mainland  China  and  is  commercialized  by  the  Company's
partner, Simcere Pharmaceutical Co., Ltd. ("Simcere"), in Greater China (mainland China, Hong Kong, Macau and Taiwan).

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  from  transient  CDK4/6  inhibition  may  protect  bone  marrow  and  the
immune  system  from  cytotoxic  damage  during  treatment.  Transient  CDK4/6  inhibition  also  may  improve  survival  in  combination  with  leading  and
emerging  treatments  by  improving  long-term  immune  surveillance.  This  can  be  accomplished  through  protection  of  the  immune  system  for  improved
longer-term function and by potentially increasing the generation of memory T cells, which can provide additional benefit after treatment. The Company is
exploring  the  use  of  trilaciclib  in  clinical  trials  to  optimize  these  potential  benefits  in  combination  with  leading  and  emerging  treatments  for  patients.
Beyond  the  Company’s  initial  ES-SCLC  indication  in  the  United  States,  the  Company  plans  to  focus  its  efforts  on  two  core  development  paths  for
trilaciclib in order to optimize the opportunity ahead, including: (1) triple negative breast cancer ("TNBC"), where trilaciclib has demonstrated potential
benefits across treatment settings in multiple Phase 2 studies, and (2) in antibody-drug conjugate ("ADC") combinations, in TNBC and potentially other
additional tumor types.

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”).

The Company has experienced net losses since its inception and has an accumulated deficit of $780.0 million and $732.0 million as of December 31, 2023
and December 31, 2022, respectively. The Company expects to incur losses and have negative net cash flows from operating activities as it executes on its
strategy including engaging in further research and development activities, particularly conducting non-clinical studies and clinical trials. The success of
the Company depends on the ability to successfully commercialize its technologies to support its operations and strategic plan. Management has evaluated
actions already taken, the significance of anticipated continued losses, future cash flow projections, and the ability of the Company to remain in compliance
with the financial covenants and requirements as defined within the Loan Agreement (as defined below). Based on the foregoing, as of the date of issuance
of these financial statements, the Company expects that its cash and cash equivalents and marketable securities as of December 31, 2023 will be sufficient
to fund the Company’s planned operations and remain in compliance with its objective financial covenants for at least the next 12 months from the date of
issuance of these financial statements. Until such time, if ever, as the Company can generate substantial revenues, the Company expects to finance its 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. There can be no assurances that the Company will be able to secure such additional financing
if at all, or on terms that are satisfactory to the Company, and that it will be sufficient to meet its needs. In the event the Company is not successful in
obtaining  sufficient  funding,  this  could  force  it  to  delay,  limit,  or  reduce  its  product  development,  commercialization  efforts  or  other  operations.  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. The financial statements do not include any adjustments relating
to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the
uncertainties described above.

F-7

In connection with the Loan Payable described in Note 7, the Company is required to be in compliance with a minimum cash covenant and is subject to a
conditional borrowing base measured on a trailing three-month net revenue basis, which began with the financial reporting for the period ended June 30,
2023, and has been tested monthly thereafter. The lender also has the ability to call debt based on a material adverse change clause, which is subjectively
defined. If the Company is not in compliance with the minimum cash covenant, conditional borrowing base requirements, or the subjective acceleration
clauses  are  triggered  under  the  agreement,  then  the  lender  may  call  the  debt  resulting  in  the  Company  immediately  needing  additional  funds.  As  of
December 31, 2023, the Company is in compliance with the minimum cash covenant and the conditional borrowing base requirements as set forth in the
Loan Agreement.

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,  common  stock  valuation,  stock-based
compensation expense and deferred tax asset valuation allowance. Actual results could differ from those estimates.

Cash, Cash Equivalents, and Restricted Cash

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,  2023  consist  of  amounts  on  deposit  in  banks,  including  checking  accounts  and  money  market
accounts  and  funds.  Cash  deposits  are  all  in  financial  institutions  in  the  United  States.  As  part  of  the  lease  for  the  office  space  which  commenced  on
September 2, 2019, 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 a money market account at the financial institution and is classified as restricted cash on the Company's 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.  Restricted  cash  totaled  $250  thousand  and
$313 thousand for the years ended December 31, 2023 and 2022, respectively.

Marketable Securities

The Company determines the appropriate classification of marketable securities at the time of purchase and reevaluates such designation at each balance
sheet date. The Company classified all of its marketable securities at December 31, 2023 as “available-for-sale” pursuant to ASC Topic 320, Investments –
Debt and Equity Securities. Investments not classified as cash equivalents are presented as either short-term or long-term investments based on both their
maturities as well as the time period the Company intends to hold such securities. Available-for-sale securities are maintained by an investment manager
and  primarily  consist  of  fixed  income  securities.  Available-for-sale  securities  are  carried  at  fair  value.  Any  premium  or  discount  arising  at  purchase  is
amortized or accreted to interest income over the life of the instrument. Realized gains and losses are determined using the specific identification method
and are included in other (income) expense, net. As of December 31, 2023, the unrealized gains and losses are not considered to be material.

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,  of  which  there  are  none  for  the  year  ended
December 31, 2023, 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.  The  Company  also  has  unbilled  accounts
receivable related to clinical trial reimbursements where the Company has the right to invoice the license partner and accordingly has recognized revenue.
Invoicing  to  the  license  partner  will  occur  once  the  Company  has  been  invoiced  by  the  service  provider.  As  of  December  31,  2023,  unbilled  accounts
receivable totaled $0.2 million.

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.

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 cost of goods sold in the period in which they are incurred.

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
Manufacturing equipment
Furniture and fixtures
Leasehold improvements

5 years
5 years
5 years
7 years
7 years

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, 2023, 2022 and 2021, the Company’s management evaluated its long-lived
assets and determined no impairment charge was needed.

Debt

The  Company  classifies  its  loan  payable  in  current  or  long-term  liabilities  based  on  the  timing  of  scheduled  principal  payments.  The  loan  and  security
agreement  with  Hercules  Capital,  Inc.  (as  amended,  the  “Loan  Agreement”)  contains  events  of  default,  including  a  material  adverse  change,  which  is
subjectively defined, in the Company’s business, payment defaults, and breaches of covenants following any applicable cure period. In the event of default
by  the  Company  under  the  Loan  Agreement,  the  Company  may  be  required  to  repay  all  amounts  then  outstanding  under  the  Loan  Agreement.  The
Company  has  determined  that  subjective  acceleration  under  the  material  adverse  events  clause  included  in  the  Loan  Agreement  is  not  probable  and,
therefore, has classified the outstanding principal amount in long-term liabilities based on the timing of scheduled principal payments.

F-9

Revenue Recognition

For elements of those arrangements that the Company determines should be accounted for under ASC 606, Revenue from Contracts with Customers (“ASC
606”), the Company assesses which activities in its license or collaboration agreements are performance obligations that should be accounted for separately
and determines 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, the Company allocates the transaction price based on the relative standalone selling price and recognizes 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, the Company develops 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 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. For regulatory milestones, the Company recognizes revenue at a point in time upon
approval,  as  that  is  when  achievement  of  the  milestone  is  considered  probable.  The  Company  assesses  milestones  as  they  are  achieved  to  determine
whether they are tied to any other performance obligations in the respective license agreements.

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). During the twelve months ended
December 31, 2023, the Company recognized $0.6 million in revenue related to sales-based royalties.

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.

F-10

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,  (e)  GPO  fees,  and  (f)  other  discounts.  Where  appropriate,  these
estimates take into consideration a range of possible outcomes 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 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,  returns,  and  GPO  fees  are  classified  as  “Accrued  Expenses”  in  the  Balance  Sheets.  Discounts  such  as
chargebacks  and  specialty  distributor  fees  are  recorded  as  a  reduction  to  trade  accounts  receivable,  which  is  included  in  “Accounts  Receivable”  in  the
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.

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.

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 for excess and obsolete inventory.

F-11

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  product,  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  estimates  and  accrues  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

Level 3

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.

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.

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

At December 31, 2023 and 2022 these financial instruments and respective fair values have been classified as follows (in thousands):

During the twelve months ended December 31, 2023 and December 31, 2022, there were no changes in valuation methodology.

The Loan Payable (discussed in Note 7), 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, 2023, the carrying value was $51.6 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 $1.8 million, $1.8 million, and $1.9 million for the
years ended December 31, 2023, 2022 and 2021, respectively.

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 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”), performance based restricted stock units (“PSUs”),
and deferred share units (“DSUs”). The fair value of RSUs, PSUs, and DSUs 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. As the PSUs have non-market performance and service conditions,
compensation expense will be recognized over the requisite service periods if and when the achievement of such performance condition(s) is determined to
be  probable  by  the  Company.  If  a  performance  condition  is  not  determined  to  be  probable  or  is  not  met,  no  stock-based  compensation  expense  is
recognized.  The  Company  reassesses  the  probability  of  achieving  the  performance  condition(s)  at  each  reporting  period.  As  of  December  31,  2023,  the
Company did not deem the achievement of any performance condition(s) to be probable and no compensation expense related to PSUs was recognized.

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.

F-13

 
 
 
 
 
 
 
 
 
 
 
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, 2023 and December 31,
2022, 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, 2023 and December 31, 2022, the Company had no such accruals.

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

The Company determines if an arrangement is a lease at inception. Operating lease assets represent the Company's right to use an underlying asset for the
lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating leases are included in operating
lease  assets,  other  current  liabilities,  and  operating  lease  liabilities  on  the  Company's  balance  sheet  at  December  31,  2023.  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  the  Company's  leases  do  not  provide  an  implicit  rate,  the  Company  uses  its  incremental  borrowing  rate  based  on  the  information  available  at
commencement date to determine the present value of future payments. The Company's lease terms may include options to extend or terminate the lease
when it is reasonably certain that it 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, the Company presents debt issuance costs on the balance sheet as a direct deduction from the associated debt.

Recent Accounting Pronouncements

From  time  to  time,  new  accounting  pronouncements  are  issued  by  the  FASB  or  other  standard  setting  bodies  and  adopted  by  the  Company  as  of  the
specified effective date. The Company did not adopt any new accounting pronouncements during the year ended December 31, 2023, that had a material
effect on its financial statements.

F-14

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." ASU 2023-07 is
intended to improve disclosures about a public entity's reportable segment by requiring additional, more detailed incremental segment information to be
disclosed on an annual and interim basis. ASU 2023-07 requires that a public entity with a single reportable segment provide all the disclosures required by
the amendments of ASU 2023-07 and all existing segment disclosures in FASB ASC Topic 280. The amendments of ASU 2023-07 require a public entity
to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and
included within each reported measure of segment profit or loss, and an amount for other segment items by reportable segment and a description of its
composition. In additional, ASU 2023-07 requires a public entity to disclose the title and position of the CODM, together with an explanation of how the
CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. ASU 2023-07 also
requires a public entity to provide all annual disclosures about a reportable segment profit or loss and assets currently required under FASB ASC Topic 280
in interim periods. The amendments of ASU 2023-07 are effective for annual periods beginning after December 15, 2023, and for interim periods with
fiscal years beginning after December 15, 2024, with early adoption permitted. The Company intends to adopt the amendments of ASU 2023-07 related to
annual disclosure requirements effective January 1, 2024, and will present any newly required annual disclosures in its Annual Report on Form 10-K for
the year ending December 31, 2024. The Company intends to adopt the amendments of ASU 2023-07 related to interim disclosure requirements effective
January 1, 2025, an will present any newly required interim disclosures beginning with its Quarterly Report on Form 10-Q for the period ending March 31,
2025. The Company is currently evaluating the changes to disclosures required by ASU 2023-07; however, adoption of ASU 2023-07 is not expected to
have a material impact to its financial position or results of operations.

In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." ASU 2023-09 is intended to
improve the disclosures for income taxes to allow investors to better assess, in their capital allocation decisions, how an entity's worldwide operations and
related tax risks and tax planning and operational opportunities affect its income tax rate and prospects for future cash flows. The amendments in ASU
2023-09 require consistent categories and greater disaggregation of information in the rate reconciliation disclosure as well as disclosure of income taxes
paid  disaggregated  by  jurisdiction.  The  amendments  of  ASU  2023-09  are  effective  for  annual  periods  beginning  after  December  15,  2024,  with  early
adoption  permitted  for  annual  financial  statements  that  have  not  yet  been  issued  or  made  available  for  issuance.  The  Company  intends  to  adopt  the
amendments of ASU 2023-09 effective January 1, 2025, and will include the required disclosures in its Annual Report on Form 10-K for the year ending
December 31, 2025. The Company is currently evaluating the changes to disclosures required by ASU 2023-09; however, adoption of ASU 2023-09 is not
expected to have a material impact to its financial position or results of operations.

The Company adopted ASC 842 as of January 1, 2019. Prior period amounts have not been adjusted and continue to be reported in accordance with the
Company's 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. The Lease term ended on December 31, 2022 and was not renewed.

F-16

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  a  money  market  account  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.

The  tables  below  reflect  the  Company’s  lease  position  and  weighted-average  lease  terms  and  discount  rates  for  its  operating  leases  as  of  December  31,
2023.  Operating  lease  liabilities  are  based  on  the  net  present  value  of  the  remaining  lease  payments  over  the  remaining  lease  term.  In  determining  the
present value of lease payments, the Company used its incremental borrowing rate based on the information available at the lease commencement date.

Cash payments included in the measurement of the Company's operating leases were $1.6 million, $1.7 million and $1.7 million for the twelve months
ended December 31, 2023, 2022, and 2021, respectively.

On  November  1,  2023,  the  Company  entered  into  an  agreement  (“Sublease”)  to  sublease  approximately  20,830  square  feet  of  office  space  at  700  Park
Offices Drive in Research Triangle Park, NC. Upon signing of the Sublease, the Company received a security deposit equal to one month's rent, which has
been recorded within other non-current liabilities on the balance sheet as of December 31, 2023. The initial fixed rental rate is $24 per rentable square foot
of the premises per annum and will increase at a rate of 2.75% per rentable square foot each year. The term of the sublease commences on January 1, 2024,
with base rent first becoming due on April 1, 2024, and has an expiration date of August 31, 2027. No sublease income was recognized during the twelve
months ended December 31, 2023, 2022, or 2021.

7. 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 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 was available through December 31, 2022.
The fourth tranche of $20.0 million was 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  initially  borrowed  under  the  original  terms  of  the  Loan  Agreement  bore  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 agreed to make interest
only payments through June 1, 2022 and following the interest only period, the Company agreed to 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 Milestone,
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.

F-18

Upon prepayment or repayment of all or any of the advances under the Loan Agreement, the Company agreed to 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 would be payable
upon any prepayment or repayment. To the extent that the Company was provided additional advances under the Loan Agreement, the 6.95% end of term
charge would 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 the first tranche.
The  Company  had  the  right  to  request  that  Hercules  make  the  remaining  $25.0  million  term  loan  advances  under  the  first  tranche  to  the  Company  by
September 15, 2022, which the Company did not exercise. 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 bore 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 Hercules 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.

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  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  accounted  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.

F-19

On  June  24,  2022,  the  Company  entered  into  a  Third  Amendment  to  Loan  and  Security  Agreement  (the  “Third  Amendment”)  with  Hercules,  which
extended the time for drawing the remainder of the first tranche advance of up to $25.0 million from September 15, 2022 to December 31, 2022, which the
Company did not exercise. The Third Amendment also added a minimum cash covenant whereby the Company must maintain unrestricted cash equal to at
least 50% of the outstanding debt, and such percentage shall decrease upon the Company achieving specified net product revenue of COSELA. It further
provided for a minimum revenue covenant that, 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 80% of the amounts projected in the
Company’s  forecast.  Testing  of  the  minimum  revenue  covenant  shall  be  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 Third Amendment under the guidance found in ASC 470-
50 Modification and Extinguishment.  The  Company  concluded  that  the  Third  Amendment  was  a  modification  and  there  was  no  impact  to  the  financial
statements.

On November 1, 2022, the Company entered into a Fourth Amendment to Loan and Security Agreement (the “Fourth Amendment”) with Hercules, which
extended the time for drawing the remainder of the first tranche advance of up to $25.0 million from December 31, 2022 to June 30, 2023. The Fourth
Amendment continued to provide for a minimum revenue covenant, tested monthly, where the Company must achieve net product revenue of COSELA of
at  least  80%  of  the  amounts  projected  in  the  Company's  forecast.  The  Fourth  Amendment  also  amended  the  minimum  cash  covenant  such  that  if  the
outstanding  debt  is  less  than  or  equal  to  $75.0  million,  the  Company  must  maintain  unrestricted  cash  equal  to  at  least  65%  of  the  outstanding  debt  in
addition  to  meeting  the  required  revenue  covenant.  In  addition,  if  the  outstanding  debt  is  greater  than  $75.0  million,  the  Company  must  maintain
unrestricted cash equal to at least 70% of the outstanding debt while meeting the revenue covenant. If the Company achieves the specified net revenue of
COSELA,  the  cash  percentage  will  decrease  to  45%  of  the  outstanding  debt.  Testing  of  the  minimum  revenue  covenant  shall  be  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 Fourth Amendment also re-set the
prepayment premiums associated with any prepayment of the loans under the Loan Agreement. The Company evaluated the Fourth Amendment under the
guidance found in ASC 470-50 Modification and Extinguishment. The Company concluded that the Fourth Amendment was a modification and there was
no impact to the financial statements.

On June 6, 2023, the Company entered into a Fifth Amendment to Loan and Security Agreement (the “Fifth Amendment”) with Hercules, under which
Hercules agreed to lend the Company up to $75.0 million, subject to specified conditions. In conjunction with the closing of the Fifth Amendment, the
Company repaid $25.0 million of the outstanding debt such that the total loan amount outstanding upon closing of the Fifth Amendment is $50.0 million. In
addition to the $25.0 million principal prepayment, upon closing of the Fifth Amendment, the Company made a $1.7 million pro-rata payment of the end-
of-term charge. The Company continues to be required to make a payment to Hercules 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  Fifth  Amendment  eliminated  advances  under  Tranches  2  and  3  and  increased  the  advance  available  under  Tranche  4  from  $15.0  million  to  $25.0
million and extended the time for drawing the Tranche 4 Advance (as defined in the Loan and Security Agreement) from June 30, 2024 to December 15,
2024.

Amounts borrowed under the Fifth 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)  5.65%,  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 conditional borrowing base compliance. 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 Fifth 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 effective date of the Fourth Amendment; (b) 2.0% of the prepayment amount in the second year from the
effective date of the Fourth Amendment; and (c) 1.0% of the prepayment amount in the third year from the effective date of the Fourth Amendment. For
the avoidance of doubt, no prepayment charge shall be applicable when repayments are required to maintain compliance with the conditional borrowing
base limit as discussed below.

F-20

The  Fifth  Amendment  amended  the  minimum  cash  covenant  such  that  the  Company  must  maintain  unrestricted  cash  equal  to  at  least  35%  of  the
outstanding debt at all times. The minimum cash covenant shall be eliminated upon the Company's achievement of quarterly net product revenue of $45.0
million or trailing six months net product revenue of $85.0 million.

The Fifth Amendment removed the existing minimum revenue covenant and provided for a conditional borrowing base limit, beginning with the financial
reporting for the period ended June 30, 2023, and tested monthly thereafter. The Fifth Amendment also provides that the Company’s debt outstanding shall
not exceed certain thresholds of trailing three month net product revenue of COSELA.

The Company evaluated the Fifth Amendment under the guidance found in ASC 470-50 Modification and Extinguishment. The Company concluded that
the Fifth Amendment was a modification; accordingly, no gain or loss was recorded. A new effective interest rate of 18.33% was established based on the
carrying value of the debt and the revised cash flows. The remaining end of term charges are accreted through interest expense through the maturity date
using  the  updated  effective  interest  rate.  The  borrowing  capacity  of  the  new  arrangement  is  less  than  the  old  arrangement.  As  such,  the  existing
unamortized  deferred  financing  costs  of  the  new  arrangement  were  written  off  in  proportion  to  the  decrease  in  the  borrowing  capacity  of  the  unfunded
portion of the arrangement. The remaining unamortized deferred financing costs are amortized to interest expense and deferred over the commitment term
of the new arrangement.

The Loan Agreement contains events of default, including a material adverse change, which is subjectively defined, in the Company’s business, payment
defaults, and breaches of covenants following any applicable cure period. In the event of default by the Company under the Loan Agreement, the Company
may be required to repay all amounts then outstanding under the Loan Agreement. The Company has determined that subjective acceleration under the
material adverse events clause included in the Loan Agreement is not probable and, therefore, has classified the outstanding principal amount in long-term
liabilities based on the timing of scheduled principal payments.

As of December 31, 2023, the outstanding debt of $50.0 million does not exceed the required threshold of trailing three month revenue for the period ended
December 31, 2023. Additionally, as of December 31, 2023 the Company maintained unrestricted cash equal to more than 35% of the total outstanding
debt and has not been notified of an event of default by the lender under the Loan Agreement.

As of December 31, 2023, the future principal payments due under the Loan Agreement, excluding interest, are as follows (in thousands):

On July 2, 2021, the Company filed an automatic shelf registration statement on Form S-3ASR 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”).  The  2021  Form  S-3  also
included a prospectus covering up to an aggregate of $150.0 million in shares of common stock that the Company may issue and sell from time to time
through Cowen and Company, LLC (“Cowen”), acting as its agent, pursuant to a sales agreement for “at the market offerings” the Company entered into
with Cowen in July 2021 (the “2021 Sales Agreement”). The Company did not sell any shares of common stock under the 2021 Sales Agreement.

At the time of the filing of the Company's Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 23, 2022,
the Company no longer qualified as a “well-known seasoned issuer” as such term is defined in Rule 405 under the Securities Act. As a result, in February
2022, the Company amended the 2021 Form S-3 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. The 2021 Form S-3, as amended,
will remain in effect for up to three years from the date it originally became effective, which was July 2, 2021. The amended 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. As of the date
hereof, the Company has not sold any shares of common stock or other securities under the 2022 Sales Agreement for “at the market offerings.”

On November 17, 2022, the Company entered into an underwriting agreement related to a public offering of 7,700,000 shares of common stock at a public
offering price of $6.50 per share less the underwriting discounts and commissions, pursuant to the shelf registration statement on Form S-3. The Company
received  approximately  $50.1  million  in  gross  proceeds  from  this  offering,  before  deducting  underwriting  discounts  and  commissions  and  offering
expenses. The offering closed on November 22, 2022. In addition, 873,353 shares of common stock were issued upon exercise by the underwriters of their
option to purchase additional shares at the same offering price, which closed on December 20, 2022. The gross proceeds from the offering of the aggregate
of 8,573,353 shares of the Company's common stock were $55.7 million and net proceeds of $52.0 million, after deducting underwriting discounts and

9. Stock-Based Compensation

2011 Equity Incentive Plan

In  March  2011,  the  Company  adopted  the  2011  Equity  Incentive  Plan  (the  “2011  Plan”).  The  2011  Plan  provided  for  the  direct  award  or  sale  of  the
Company’s common stock and for the grant of stock options to employees, directors, officers, consultants and advisors of the Company. The 2011 Plan was
subsequently  amended  in  August  2012,  October  2013,  February  2015,  December  2015,  April  2016  and  November  2016  to  allow  for  the  issuance  of
additional  shares  of  common  stock.  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,  2023,  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.

In January 2021, the Company began granting RSUs under the 2017 Plan. RSUs are granted at the fair market value of a share of common stock on the
date of grant.

In January 2023, the Company began granting PSUs, which are subject to non-market performance and service conditions, to Company executives under
the 2017 Plan. PSUs are granted at the fair market value of a share of common stock on the date of grant.

In May 2023, the Company adopted the G1 Therapeutics, Inc. Deferred Compensation Plan for Non-Employee Directors to enable non-employee directors
of the Company (each a “Non-Employee Director”) to elect to defer annually the receipt of shares that vest in accordance with the terms of RSUs granted
under the 2017 Plan (the “Vested RSUs”) for service as a Non-Employee Director (the “Deferred Compensation Plan”). The Deferred Compensation Plan
is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended. Under the Deferred Compensation Plan,
the Non-Employee Directors shall be entitled to file with the Compensation Committee of the Board prior to December 31 of each Plan Year (as defined
therein) an election form so as to make an election under the Deferred Compensation Plan effective for the following Plan Year, pursuant to which a Non-
Employee Director may elect to defer receipt of shares underlying Vested RSUs with respect to RSUs granted in the following Plan Year. The Deferred
Compensation Plan is unfunded and unsecured.

As of December 31, 2023, there were a total of 1,473,163 shares of common stock available for future issuance under the 2017 Plan.

Amended and Restated 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.

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.

F-23

In  March  2022,  the  Company  merged  the  2021  Sales  Force  Inducement  Plan  into  the  2021  Inducement  Plan  and  amended  and  restated  the  2021
Inducement Plan to create the Amended and Restated 2021 Inducement Equity Incentive Plan (the “Amended and Restated 2021 Plan”). In addition, the
number of shares reserved for issuance under the Amended and Restated 2021 Plan was increased by 750,000 shares of the Company’s common stock, for
an  aggregate  of  1,750,000  shares  of  the  Company’s  common  stock  authorized  to  issue  under  the  Amended  and  Restated  2021  Plan.  The  Amended  and
Restated 2021 Plan does not include an evergreen provision.

As of December 31, 2023, there was a total of 911,870 shares of common stock available for future issuance under the Amended and Restated 2021 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.  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, PSUs, and DSUs. The fair value of RSUs, PSUs, and DSUs 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. As the
PSUs have non-market performance and service conditions, compensation expense will be recognized over the requisite service periods if and when the
achievement of such performance condition(s) is determined to be probable by the Company. If a performance condition is not determined to be probable
or is not met, no stock-based compensation expense is recognized. The Company reassesses the probability of achieving the performance condition(s) at
each  reporting  period.  As  of  December  31,  2023,  the  Company  did  not  deem  the  achievement  of  any  performance  condition(s)  to  be  probable  and  no
compensation expense related to PSUs was recognized.

The table below summarizes the stock-based compensation expense recognized in the Company’s statement of operations by classification (in thousands):

Stock options – Black-Scholes inputs

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  granted  was  determined  using  the  simplified  method  under  SAB  107  which  represents  the  mid-point  between  the
vesting term and the contractual term.

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 continued to use the guideline peer group volatility information
until April 2023, when the historical volatility of its common stock became 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.

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.

Performance Based Restricted Stock Units

The Company's performance based restricted stock units (“PSUs”) are considered nonvested share awards and require no payment from the employee. For
each PSU, employees receive one common share at the end of the vesting period, subject to non-market performance and service conditions. Compensation
cost is recorded based on the market price of the Company's common stock on the grant date and is recognized over the requisite service if and when the
achievement  of  such  performance  condition(s)  is  determined  to  be  probable  by  the  Company.  The  Company  reassesses  the  probability  of  achieving  the
performance condition(s) at each reporting period. As of December 31, 2023, the Company did not deem the achievement of any performance condition(s)
to be probable and compensation expense related to PSUs was not recognized.

Deferred Share Units

The Company's DSUs are considered nonvested share awards and require no payment from the holders. For each DSU, holders receive one common share
on a future date, generally upon “Separation from Service” (within the meaning of Section 409A of the Code) as a Non-Employee Director of the Company
for any reason. Upon settlement, holders will receive one fully paid and non-assessable common share in respect of each vested DSU. 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.

10. License Revenue

Incyclix License Agreement

On May 22, 2020, the Company entered into an exclusive license agreement with Incyclix Bio, LLC (“Incyclix”), formerly ARC Therapeutics, LLC, a
company primarily owned by a former board member, whereby the Company granted to Incyclix 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
Incyclix 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.  In  the  first  quarter  of  2022,  Incyclix  announced  a  new  round  of  financing  which  the
Company did not participate. Following the financing, the Company's equity interest is now approximately 6.5%.

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 Incyclix 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 Incyclix 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 Incyclix to benefit from the license.

The Company considers the future potential development milestone 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, 2023.

F-27

 
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  Australia,  Bangladesh,  China,  Hong  Kong,  India,  Indonesia,  Macau,  Malaysia,  Myanmar,  New  Zealand,  Pakistan,
Philippines,  Singapore,  South  Korea,  Sri  Lanka,  Taiwan,  Thailand,  and  Vietnam  (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. Since then, through December 31, 2022, the Company had recognized
an additional $3.0 million in revenue for the achievement of development and commercial milestones as defined by the license agreement.

There was no milestone revenue recognized during the twelve months ended December 31, 2023.

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  would  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  was  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 was responsible for the development of the
product in the EQRx Territory. The Company agreed to continue until completion, as the clinical trial sponsor, its two primary clinical trials and EQRx
agreed to reimburse the Company for all related out-of-pocket costs incurred after the effective date of the license agreement.

On August 1, 2023, the Company received from EQRx formal notice of termination of the lerociclib license agreement in connection with the acquisition
of EQRx by Revolution Medicines, Inc. The notice stated the intention to revert the lerociclib product rights back to the Company. Under the terms of the
license agreement, EQRx is responsible for winding down its development activities. On September 13, 2023, the parties entered into a letter agreement
whereby EQRx would pay the Company $1.6 million to reimburse anticipated wind down costs; the payment was received during the third quarter of 2023.
No milestones were previously achieved through the date of termination of the lerociclib license agreement, and as a result of the termination, the Company
will not receive any further milestone payments or future royalties from EQRx.

During the twelve months ended December 31, 2023, the Company recognized revenue of $1.7 million for the reimbursement of patent and clinical trial
costs,  including  $1.4  million  of  the  $1.6  million  payment  received  during  the  third  quarter  of  2023  following  notice  from  EQRx  of  termination  of  the
license agreement. As of December 31, 2023, the remaining $0.2 million is held as short-term deferred revenue on the balance sheet and will be recognized
as revenue as clinical trial costs associated with the wind down are incurred.

F-28

Simcere License Agreement

On August 3, 2020, the Company entered into an exclusive license agreement with 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. Since entering into the license agreement, the Company had received an
upfront payment of $14.0 million and an additional $22.0 million for the achievement of development milestones through December 31, 2022.

On April 28, 2023, the Company amended the license agreement with Simcere, whereby the Company received a one-time, non-refundable payment of
$30.0 million in exchange for the relief of future royalty payments from the sale of COSELA in Greater China. In addition, the milestone payments under
the license agreement were adjusted such that the Company will be eligible to receive a $5.0 million payment upon Simcere’s filing an NDA of TNBC in
mainland  China  and  a  $13.0  million  payment  upon  Simcere  receiving  regulatory  approval  of  TNBC  in  mainland  China.  Under  the  amended  license
agreement,  Simcere  is  not  responsible  for  any  sales  milestone  payments  or  any  royalties  accrued  after  April  28,  2023.  Following  the  amendment,  the
Company continues to own all the global development and commercial rights to trilaciclib, excluding Greater China.

During the twelve months ended December 31, 2023, the Company recognized $30.0 million in revenue from the one-time payment for the relief of future
royalty  payments,  $2.9  million  in  supply  and  manufacturing  services,  $0.6  million  in  royalty  revenue,  and  $0.7  million  in  patent  and  clinical  trial
reimbursable costs.

11. 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 twelve months ended December 31, 2023, 2022 and 2021, the following potentially
dilutive securities have been excluded from the computations of diluted weighted-average shares outstanding because the effect would be anti-dilutive:

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.

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 in the year ended December 31, 2021, which was offset fully by the reduction in the
corresponding valuation allowance. To the extent 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.

At December 31, 2023 and December 31, 2022, 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 $9.9 million
from $173.9 million at December 31, 2022 to $183.7 million at December 31, 2023. The increase in valuation allowance was due primarily to the increase
in net operating loss carryforwards, capitalized research and experimentation costs, and income tax credits.

At December 31, 2023, the Company has federal net operating loss carryforwards (“NOLs”) of approximately $550.7 million, which are available to offset
future  taxable  income.  Of  the  $550.7  million  available,  $93.5  million  will  begin  to  expire  in  2029.  The  remaining  $457.2  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 $401.2 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, 2023, the Company also had federal research and development (R&D) credit carryforwards of approximately
$23.4 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, 2023 and 2022, 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,
2023 and 2022, 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 assets associated with them will not be
realized regardless of whether an “ownership change” has occurred.

13. Related Party Transactions

On September 19, 2023, Mark A. Velleca, M.D., Ph.D., notified the Company of his decision to resign from the Company's Board of Directors, effective as
of September 30, 2023. Dr. Velleca was a member of the Board since May 2014. Dr. Velleca’s decision to resign was not due to any disagreement with the
Company on any matter relating to the Company’s operations, policies or practices.

Dr. Velleca will continue to serve as a senior advisor to the Company pursuant to the terms of a Senior Advisor Agreement dated September 29, 2020 (the
“Agreement”), as amended by that certain First Amendment to Senior Advisor Agreement, dated as of September 20, 2023 (the “Amendment”). Pursuant
to the terms of the Agreement, Dr. Velleca was paid in equal quarterly installments, for his services, of which one final installment of $50,000 has not been
paid as of December 31, 2023.

Pursuant to the Amendment, the term of the Agreement has been extended from December 31, 2023 to December 31, 2024. Dr. Velleca will not receive any
cash or equity compensation for his services during the period from January 1, 2024 through December 31, 2024 (the “Extended Term”). However, any
stock options held by Dr. Velleca will continue to vest in accordance with their terms during the Extended Term.

EXHIBIT 10.25

G1 THERAPEUTICS, INC.

AMENDED AND RESTATED CLAWBACK POLICY
(Effective December 1, 2023)

I.    INTRODUCTION

The Board of Directors (the “Board”) of G1 Therapeutics, Inc. (the “Company”), believes that it is in the best interests of
the Company and its shareholders to create and maintain a corporate culture that emphasizes integrity and accountability and that
reinforces the Company’s pay-for-performance compensation philosophy. The Board has therefore adopted this amended and
restated policy as of December 1, 2023 (the “Effective Date”), which provides for the recoupment of certain executive
compensation in the event of an accounting restatement resulting from material noncompliance with financial reporting
requirements under the federal securities laws (the “Policy”). This Policy was initially adopted by the Company on December 1,
2022 and was amended and restated on the Effective Date. This Policy is designed to comply with Section 10D of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), and final rules and amendments adopted by the Securities and
Exchange Commission (the “SEC”) to implement the aforementioned legislation.

II.    ADMINISTRATION

This Policy shall be administered by the Board or, if so designated by the Board, the Compensation Committee in which

case references herein to the Board shall be deemed references to the Compensation Committee. Any determinations made by the
Board shall be final and binding on all affected individuals.

III.    COVERED EXECUTIVES

This Policy applies to the Company’s current and former executive officers, as determined by the Board in accordance
with the requirements of Section 10D of the Exchange Act and any applicable rules or standards adopted by the SEC and any
national securities exchange on which the Company’s securities are listed (the “Applicable Rules”), and such other employees
who may from time to time be deemed subject to the Policy by the Board (“Covered Executives”).

IV.    INCENTIVE-BASED COMPENSATION

For purposes of this Policy, incentive-based compensation (“Incentive-Based Compensation”) includes any compensation

that is granted, earned, or vested based wholly or in part upon the attainment of any financial reporting measures that are
determined and presented in accordance with the accounting principles (“GAAP Measures”) used in preparing the Company’s
financial statements and any measures derived wholly or in part from such measures, as well as non-GAAP Measures, stock
price, and total shareholder return (collectively, “Financial Reporting Measures”); however, it does not include: (i) base salaries;
(ii) discretionary cash bonuses; (iii) awards (either cash or equity) that are solely based upon subjective, strategic or operational
standards or standards unrelated to Financial Reporting Measures, and (iv) equity awards that vest solely on completion of a
specified employment period or without any performance condition. Incentive-Based Compensation is considered received in the
fiscal period during which the applicable reporting measure is attained, even if the payment or grant of such award occurs after
the end of that period. If an award is subject to both time-based and performance-based vesting conditions, the award is
considered received upon satisfaction of the

performance-based conditions, even if such award continues to be subject to the time-based vesting conditions.

For the purposes of this Policy, Incentive-Based Compensation may include, among other things:

· Annual bonuses and other short-term and long-term cash incentives;

·

·

Stock options;

Stock appreciation rights;

· Restricted stock;
· Restricted stock units;

·

·

Performance shares; and

Performance units.

For the purposes of this Policy, Financial Reporting Measures may include, among other things:

· Company stock price;

· Total shareholder return;
· Revenues;

· Net income;

· Earnings before interest, taxes, depreciation, and amortization;

Funds from operations;

·
· Liquidity measures such as working capital or operating cash flow;

· Return measures such as return on invested capital or return on assets; and

· Earnings measures such as earnings per share.

V.    RECOUPMENT; ACCOUNTING RESTATEMENT

In the event the Company is required to prepare an accounting restatement of its financial statements due to the
Company’s material noncompliance with any financial reporting requirement under U.S. securities laws, including any required
accounting restatement to correct an error in previously issued financial statements that (i) is material to the previously issued
financial statements or (ii) is not material to previously issued financial statements, but that would result in a material
misstatement if the error were corrected in the current period or left uncorrected in the current period, the Board will require
reimbursement or forfeiture of any excess Incentive-Based Compensation received by any Covered Executive during the three
completed fiscal years immediately preceding the date on which the Company is required to prepare the accounting restatement
(the “Look-Back Period”). For the purposes of this Policy, the date on which the Company is required to prepare an accounting
restatement is the earlier of (i) the date the Board concludes or reasonably should have concluded that the Company is required to
prepare a restatement to correct a material error, and (ii) the date a court, regulator, or other legally authorized body directs the
Company to restate its previously issued financial statements to correct a material error. The Company’s obligation to recover
erroneously awarded compensation is not dependent on if or when the restated financial statements are filed.

2

Recovery of the Incentive-Based Compensation is only required when the excess award is received by a Covered

Executive (i) after the beginning of their service as a Covered Executive, (ii) who served as an executive officer at any time
during the performance period for that Incentive-Based Compensation, (iii) while the Company has a class of securities listed on
a national securities exchange or a national securities association, and (iv) during the Look-Back Period immediately preceding
the date on which the Company is required to prepare an accounting restatement.

VI.    EXCESS INCENTIVE COMPENSATION: AMOUNT SUBJECT TO RECOVERY

The amount of Incentive-Based Compensation subject to recovery is the amount the Covered Executive received in
excess of the amount of Incentive-Based Compensation that would have been paid to the Covered Executive had it been based on
the restated financial statements, as determined by the Board. The amount subject to recovery will be calculated on a pre-tax
basis.

For Incentive-Based Compensation received as cash awards, the erroneously awarded compensation is the difference

between the amount of the cash award that was received (whether payable in a lump sum or over time) and the amount that
should have been received applying the restated Financial Reporting Measure. For cash awards paid from bonus pools, the
erroneously awarded Incentive-Based Compensation is the pro rata portion of any deficiency that results from the aggregate
bonus pool that is reduced based on applying the restated Financial Reporting Measure.

For Incentive-Based Compensation received as equity awards that are still held at the time of recovery, the amount subject

to recovery is the number of shares or other equity awards received or vested in excess of the number that should have been
received or vested applying the restated Financial Reporting Measure. If the equity award has been exercised, but the underlying
shares have not been sold, the erroneously awarded compensation is the number of shares underlying the award.

In instances where the Company is not able to determine the amount of erroneously awarded Incentive-Based

Compensation directly from the information in the accounting restatement, the amount will be based on the Company’s
reasonable estimate of the effect of the accounting restatement on the applicable measure. In such instances, the Company will
maintain documentation of the determination of that reasonable estimate.

VII.    METHOD OF RECOUPMENT

The Board will determine, in its sole discretion, subject to applicable law, the method for recouping Incentive-Based

Compensation hereunder, which may include, without limitation:

• Requiring reimbursement of cash Incentive-Based Compensation previously paid;
•

Seeking recovery of any gain realized on the vesting, exercise, settlement, sale, transfer, or other disposition of any
equity-based awards;

• Offsetting the recouped amount from any compensation otherwise owed by the Company to the Covered Executive;
• Cancelling outstanding vested or unvested equity awards; and

• Taking any other remedial and recovery action permitted by law, as determined by the Board.

3

IIX.    NO INDEMNIFICATION

The Company shall not indemnify any Covered Executives against the loss of any incorrectly awarded Incentive-Based

Compensation.

IX    INTERPRETATION

The Board is authorized to interpret and construe this Policy and to make all determinations necessary, appropriate, or

advisable for the administration of this Policy. It is intended that this Policy be interpreted in a manner that is consistent with the
requirements of Section 10D of the Exchange Act and any Applicable Rules.

X.    EXCEPTIONS TO ENFORCEMENT

The Board shall recover any excess Incentive-Based Compensation in accordance with this Policy unless such recovery

would be impracticable, as determined by the Board in accordance with Rule 10D-1 of the Exchange Act and any Applicable
Rules.

XI.    EFFECTIVE DATE

This Policy shall be effective as of the Effective Date and shall apply to Incentive-Based Compensation that is received by

a Covered Executive on or after October 2, 2023, as determined by the Board in accordance with any Applicable Rules.

XII.    AMENDMENT

The Board may amend this Policy from time to time in its discretion and shall amend this Policy as it deems necessary to

comply with any Applicable Rules. The Board may terminate this Policy at any time.

XIII.    OTHER RECOUPMENT RIGHTS

Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies or rights of recoupment

that may be available to the Company pursuant to the terms of any similar policy in any employment agreement, equity award
agreement, or similar agreement and any other legal remedies available to the Company.

INCORPORATED TERMS AND CONDITIONS

AGREEMENT (this “Agreement”) made as of the date of grant set forth in the Restricted Stock Unit Award Grant Notice
between  G1  Therapeutics,  Inc.  (the  “Company”),  a  Delaware  corporation,  and  the  individual  whose  name  appears  on  the
Restricted Stock Unit Award Grant Notice (the “Participant”).

WHEREAS, the Company has adopted the Amended and Restated 2017 Employee, Director and Consultant Equity
Incentive Plan (the “Plan”), to promote the interests of the Company by providing an incentive for Employees, directors and
Consultants of the Company and its Affiliates;

WHEREAS, pursuant to the provisions of the Plan, the Company desires to grant to the Participant restricted stock units
(“RSUs”)  related  to  the  Company’s  common  stock,  $0.0001  par  value  per  share  (“Common  Stock”),  in  accordance  with  the
provisions of the Plan, all on the terms and conditions hereinafter set forth; and

WHEREAS, the Company and the Participant understand and agree that any terms used and not defined herein have the

meanings ascribed to such terms in the Plan.

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein and for other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.

Grant of Award. The Company hereby grants to the Participant an award for the number of RSUs set forth in the
Restricted  Stock  Unit  Award  Grant  Notice  (the  “Award”).  Each  RSU  represents  a  contingent  entitlement  of  the  Participant  to
receive one share of Common Stock, on the terms and conditions and subject to all the limitations set forth herein and in the Plan,
which is incorporated herein by reference. The Participant acknowledges receipt of a copy of the Plan.

2.

Vesting of Award.

(a)

Subject  to  the  terms  and  conditions  set  forth  in  this  Agreement  and  the  Plan,  the  Award  granted  hereby
shall vest as set forth in the Restricted Stock Unit Award Grant Notice and is subject to the other terms and conditions of this
Agreement and the Plan. On each vesting date set forth in the Restricted Stock Unit Award Grant Notice, the Participant shall be
entitled to receive such number of shares of Common Stock equivalent to the number of RSUs as set forth in the Restricted Stock
Unit Award Grant Notice provided that the Participant is employed or providing services to the Company or an Affiliate on such
vesting date. Such shares of Common Stock shall thereafter be delivered by the Company to the Participant within five days of
the applicable vesting date and in accordance with this Agreement and the Plan.

(b)

Except  as  otherwise  set  forth  in  this  Agreement,  if  the  Participant  ceases  to  be  employed  or  providing
services for any reason by the Company or by an Affiliate (the “Termination”) prior to a vesting date set forth in the Restricted
Stock Unit Award Grant Notice, then as of the date on which the Participant’s employment or service terminates, all unvested
RSUs shall immediately be forfeited to the Company and this Agreement shall terminate and be of no further force or effect.

3.

Prohibitions  on  Transfer  and  Sale. This  Award  (including  any  additional  RSUs  received  by  the  Participant  as  a
result  of  stock  dividends,  stock  splits  or  any  other  similar  transaction  affecting  the  Company’s  securities  without  receipt  of
consideration) shall not be transferable by the Participant otherwise than (i) by will or by the laws of descent and distribution, or
(ii)  pursuant  to  a  qualified  domestic  relations  order  as  defined  by  the  Internal  Revenue  Code  or  Title  I  of  the  Employee
Retirement  Income  Security  Act  or  the  rules  thereunder.  Except  as  provided  in  the  previous  sentence,  the  shares  of  Common
Stock to be issued pursuant to this Agreement shall be issued, during the Participant’s lifetime, only to the Participant (or, in the
event  of  legal  incapacity  or  incompetence,  to  the  Participant’s  guardian  or  representative).  This  Award  shall  not  be  assigned,
pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment
or similar process. Any attempted transfer, assignment, pledge, hypothecation or other disposition of this Award or of any rights
granted hereunder contrary to the provisions of this Section 3, or the levy of any attachment or similar process upon this Award
shall be null and void.

4.

Adjustments.  The  Plan  contains  provisions  covering  the  treatment  of  RSUs  and  shares  of  Common  Stock  in  a
number of contingencies such as stock splits. Provisions  in  the  Plan  for  adjustment  with  respect  to  this  Award  and  the  related
provisions with respect to successors to the business of the Company are hereby made applicable hereunder and are incorporated
herein by reference.

5.

Securities  Law  Compliance.  The  Participant  specifically  acknowledges  and  agrees  that  any  sales  of  shares  of
Common  Stock  shall  be  made  in  accordance  with  the  requirements  of  the  Securities  Act  of  1933,  as  amended.  The  Company
currently  has  an  effective  registration  statement  on  file  with  the  Securities  and  Exchange  Commission  with  respect  to  the
Common Stock to be granted hereunder. The Company intends to maintain this registration statement but has no obligation to do
so. If the registration statement ceases to be effective for any reason, Participant will not be able to transfer or sell any of the
shares  of  Common  Stock  issued  to  the  Participant  pursuant  to  this  Agreement  unless  exemptions  from  registration  or  filings
under applicable securities laws are available. Furthermore, despite registration, applicable securities laws may restrict the ability
of the Participant to sell his or her Common Stock, including due to the Participant’s affiliation with the Company. The Company
shall not be obligated to either issue the Common Stock or permit the resale of any shares of Common Stock if such issuance or
resale would violate any applicable securities law, rule or regulation.

6.

Rights as a Stockholder. The Participant shall have no right as a stockholder, including voting and dividend rights,

with respect to the RSUs subject to this Agreement.

7.

Incorporation  of  the  Plan.  The  Participant  specifically  understands  and  agrees  that  the  RSUs  and  the  shares  of
Common  Stock  to  be  issued  under  the  Plan  will  be  issued  to  the  Participant  pursuant  to  the  Plan,  a  copy  of  which  Plan  the
Participant acknowledges he or she has read and understands and by which Plan he or she agrees to be bound. The provisions of
the Plan are incorporated herein by reference.

8.

Tax Liability of the Participant and Payment of Taxes. The Participant acknowledges and agrees that any income
or other taxes due from the Participant with respect to this Award or the shares of Common Stock to be issued pursuant to this
Agreement or otherwise sold shall be the Participant’s responsibility. Without limiting the foregoing, the Participant agrees that if
under applicable law the Participant will owe taxes at each vesting date on the portion of the Award then vested the Company
shall be entitled to immediate payment from the Participant of the amount of any tax or other amounts required to be withheld by
the Company by applicable law or regulation. Any taxes or other amounts due shall be paid, at the option of the Administrator as
follows:

2

(a)

through  reducing  the  number  of  shares  of  Common  Stock  entitled  to  be  issued  to  the  Participant  on  the
applicable  vesting  date  in  an  amount  equal  to  the  statutory  minimum  of  the  Participant’s  total  tax  and  other  withholding
obligations  due  and  payable  by  the  Company.  Fractional  shares  will  not  be  retained  to  satisfy  any  portion  of  the  Company’s
withholding obligation. Accordingly, the Participant agrees that in the event that the amount of withholding required would result
in  a  fraction  of  a  share  being  owed,  that  amount  will  be  satisfied  by  withholding  the  fractional  amount  from  the  Participant’s
paycheck;

(b)

requiring the Participant to deposit with the Company an amount of cash equal to the amount determined
by the Company to be required to be withheld with respect to the statutory minimum amount of the Participant’s total tax and
other  withholding  obligations  due  and  payable  by  the  Company  or  otherwise  withholding  from  the  Participant’s  paycheck  an
amount equal to such amounts due and payable by the Company; or

(c)

by requiring the sale by the Participant on the applicable vesting date of such number of shares of Common
Stock as the Company instructs a registered broker to sell to satisfy the Company’s withholding obligation, after deduction of the
broker’s commission, and the broker shall be required to remit to the Company the cash necessary in order for the Company to
satisfy  its  withholding  obligation.  Such  sales  shall  be  made  pursuant  to  a  mandatory  “sell-to-cover”  program  instituted  by  the
Company  with  no  discretion  by  the  Participant  with  respect  to  any  sale  under  the  “sell-to-cover”  program.  To  the  extent  the
proceeds  of  such  sale  exceed  the  Company’s  withholding  obligation  the  Company  agrees  to  pay  such  excess  cash  to  the
Participant  as  soon  as  practicable.  In  addition,  if  such  sale  is  not  sufficient  to  pay  the  Company’s  withholding  obligation  the
Participant agrees to pay to the Company as soon as practicable, including through additional payroll withholding, the amount of
any  withholding  obligation  that  is  not  satisfied  by  the  sale  of  shares  of  Common  Stock.  The  Participant  agrees  to  hold  the
Company and the broker harmless from all costs, damages or expenses relating to any such sale. The Participant acknowledges
that the Company and the broker are under no obligation to arrange for such sale at any particular price. In connection with such
sale of shares of Common Stock, the Participant shall execute any such documents requested by the broker in order to effectuate
the sale of shares of Common Stock and payment of the withholding obligation to the Company.

(d)

G1 Therapeutics, Inc.

RESTRICTED STOCK UNIT AGREEMENT –

INCORPORATED TERMS AND CONDITIONS

AGREEMENT (this “Agreement”) made as of the date of grant set forth in the Restricted Stock Unit Award Grant Notice
between  G1  Therapeutics,  Inc.  (the  “Company”),  a  Delaware  corporation,  and  the  individual  whose  name  appears  on  the
Restricted Stock Unit Award Grant Notice (the “Participant”).

WHEREAS, the Company has adopted the Amended and Restated 2021 Inducement Equity Incentive Plan (the “Plan”),

to promote the interests of the Company by providing an incentive for Employees and Directors of the Company;

WHEREAS, pursuant to the provisions of the Plan, the Company desires to grant to the Participant restricted stock units
(“RSUs”)  related  to  the  Company’s  common  stock,  $0.0001  par  value  per  share  (“Common  Stock”),  in  accordance  with  the
provisions of the Plan, all on the terms and conditions hereinafter set forth; and

WHEREAS, the Company and the Participant understand and agree that any terms used and not defined herein have the

meanings ascribed to such terms in the Plan.

NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein and for other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.

Grant of Award. The Company hereby grants to the Participant an award for the number of RSUs set forth in the
Restricted  Stock  Unit  Award  Grant  Notice  (the  “Award”).  Each  RSU  represents  a  contingent  entitlement  of  the  Participant  to
receive one share of Common Stock, on the terms and conditions and subject to all the limitations set forth herein and in the Plan,
which is incorporated herein by reference. The Participant acknowledges receipt of a copy of the Plan. The Company and the
Participant understand and agree that the Award shall be granted in compliance with Nasdaq Listing Rule 5635(c)(4) as a material
inducement to the Participant entering into employment with the Company.

2.

Vesting of Award.

(a)

Subject  to  the  terms  and  conditions  set  forth  in  this  Agreement  and  the  Plan,  the  Award  granted  hereby
shall vest as set forth in the Restricted Stock Unit Award Grant Notice and is subject to the other terms and conditions of this
Agreement and the Plan. On each vesting date set forth in the Restricted Stock Unit Award Grant Notice, the Participant shall be
entitled to receive such number of shares of Common Stock equivalent to the number of RSUs as set forth in the Restricted Stock
Unit Award Grant Notice provided that the Participant is employed by or providing services to the Company or an Affiliate on
such vesting date. Such shares of Common Stock shall thereafter be delivered by the Company to the Participant within five days
of the applicable vesting date and in accordance with this Agreement and the Plan.

(b)

Except  as  otherwise  set  forth  in  this  Agreement,  if  the  Participant  ceases  to  be  employed  or  providing
services for any reason by the Company or by an Affiliate (the “Termination”) prior to a vesting date set forth in the Restricted
Stock Unit Award Grant Notice, then as of the date on which the Participant’s employment or service terminates, all unvested
RSUs shall immediately be forfeited to the Company and this Agreement shall terminate and be of no further force or effect.

3.

Prohibitions  on  Transfer  and  Sale. This  Award  (including  any  additional  RSUs  received  by  the  Participant  as  a
result  of  stock  dividends,  stock  splits  or  any  other  similar  transaction  affecting  the  Company’s  securities  without  receipt  of
consideration) shall not be transferable by the Participant otherwise than (i) by will or by the laws of descent and distribution, or
(ii)  pursuant  to  a  qualified  domestic  relations  order  as  defined  by  the  Internal  Revenue  Code  or  Title  I  of  the  Employee
Retirement  Income  Security  Act  or  the  rules  thereunder.  Except  as  provided  in  the  previous  sentence,  the  shares  of  Common
Stock to be issued pursuant to this Agreement shall be issued, during the Participant’s lifetime, only to the Participant (or, in the
event  of  legal  incapacity  or  incompetence,  to  the  Participant’s  guardian  or  representative).  This  Award  shall  not  be  assigned,
pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment
or similar process. Any attempted transfer, assignment, pledge, hypothecation or other disposition of this Award or of any rights
granted hereunder contrary to the provisions of this Section 3, or the levy of any attachment or similar process upon this Award
shall be null and void.

4.

Adjustments.  The  Plan  contains  provisions  covering  the  treatment  of  RSUs  and  shares  of  Common  Stock  in  a
number of contingencies such as stock splits. Provisions  in  the  Plan  for  adjustment  with  respect  to  this  Award  and  the  related
provisions with respect to successors to the business of the Company are hereby made applicable hereunder and are incorporated
herein by reference.

5.

Securities  Law  Compliance.  The  Participant  specifically  acknowledges  and  agrees  that  any  sales  of  shares  of
Common  Stock  shall  be  made  in  accordance  with  the  requirements  of  the  Securities  Act  of  1933,  as  amended.  The  Company
currently  has  an  effective  registration  statement  on  file  with  the  Securities  and  Exchange  Commission  with  respect  to  the
Common Stock to be granted hereunder. The Company intends to maintain this registration statement but has no obligation to do
so. If the registration statement ceases to be effective for any reason, Participant will not be able to transfer or sell any of the
shares  of  Common  Stock  issued  to  the  Participant  pursuant  to  this  Agreement  unless  exemptions  from  registration  or  filings
under applicable securities laws are available. Furthermore, despite registration, applicable securities laws may restrict the ability
of the Participant to sell his or her Common Stock, including due to the Participant’s affiliation with the Company. The Company
shall not be obligated to either issue the Common Stock or permit the resale of any shares of Common Stock if such issuance or
resale would violate any applicable securities law, rule or regulation.

6.

Rights as a Stockholder. The Participant shall have no right as a stockholder, including voting and dividend rights,

with respect to the RSUs subject to this Agreement.

2

7.

Incorporation  of  the  Plan.  The  Participant  specifically  understands  and  agrees  that  the  RSUs  and  the  shares  of
Common  Stock  to  be  issued  under  the  Plan  will  be  issued  to  the  Participant  pursuant  to  the  Plan,  a  copy  of  which  Plan  the
Participant acknowledges he or she has read and understands and by which Plan he or she agrees to be bound. The provisions of
the Plan are incorporated herein by reference.

8.

Tax Liability of the Participant and Payment of Taxes. The Participant acknowledges and agrees that any income
or other taxes due from the Participant with respect to this Award or the shares of Common Stock to be issued pursuant to this
Agreement or otherwise sold shall be the Participant’s responsibility. Without limiting the foregoing, the Participant agrees that if
under applicable law the Participant will owe taxes at each vesting date on the portion of the Award then vested the Company
shall be entitled to immediate payment from the Participant of the amount of any tax or other amounts required to be withheld by
the Company by applicable law or regulation. Any taxes or other amounts due shall be paid, at the option of the Administrator as
follows:

(a)

through  reducing  the  number  of  shares  of  Common  Stock  entitled  to  be  issued  to  the  Participant  on  the
applicable  vesting  date  in  an  amount  equal  to  the  statutory  minimum  of  the  Participant’s  total  tax  and  other  withholding
obligations  due  and  payable  by  the  Company.  Fractional  shares  will  not  be  retained  to  satisfy  any  portion  of  the  Company’s
withholding obligation. Accordingly, the Participant agrees that in the event that the amount of withholding required would result
in  a  fraction  of  a  share  being  owed,  that  amount  will  be  satisfied  by  withholding  the  fractional  amount  from  the  Participant’s
paycheck;

(b)

requiring the Participant to deposit with the Company an amount of cash equal to the amount determined
by the Company to be required to be withheld with respect to the statutory minimum amount of the Participant’s total tax and
other  withholding  obligations  due  and  payable  by  the  Company  or  otherwise  withholding  from  the  Participant’s  paycheck  an
amount equal to such amounts due and payable by the Company; or

(c)

by requiring the sale by the Participant on the applicable vesting date of such number of shares of Common
Stock as the Company instructs a registered broker to sell to satisfy the Company’s withholding obligation, after deduction of the
broker’s commission, and the broker shall be required to remit to the Company the cash necessary in order for the Company to
satisfy  its  withholding  obligation.  Such  sales  shall  be  made  pursuant  to  a  mandatory  “sell-to-cover”  program  instituted  by  the
Company  with  no  discretion  by  the  Participant  with  respect  to  any  sale  under  the  “sell-to-cover”  program.  To  the  extent  the
proceeds  of  such  sale  exceed  the  Company’s  withholding  obligation  the  Company  agrees  to  pay  such  excess  cash  to  the
Participant  as  soon  as  practicable.  In  addition,  if  such  sale  is  not  sufficient  to  pay  the  Company’s  withholding  obligation  the
Participant agrees to pay to the Company as soon as practicable, including through additional payroll withholding, the amount of
any  withholding  obligation  that  is  not  satisfied  by  the  sale  of  shares  of  Common  Stock.  The  Participant  agrees  to  hold  the
Company and the broker harmless from all costs, damages or expenses relating to any such sale. The Participant acknowledges
that the Company and the broker are under no obligation to arrange for such sale at any particular price. In connection with such
sale of shares of Common Stock, the Participant shall execute any such documents requested by the broker in order to effectuate
the sale of shares of Common Stock and payment of the withholding obligation to the Company.

(d)

It  is  the  Company’s  intention  that  the  Participant’s  tax  obligations  under  this  Section  8  shall  be  satisfied
through the procedure of Subsection (c) above, unless the Company provides notice of an alternate procedure under this Section,
in  its  discretion.  The  Company  shall  not  deliver  any  shares  of  Common  Stock  to  the  Participant  until  it  is  satisfied  that  all
required withholdings have been made.

EMPLOYMENT AGREEMENT

This EMPLOYMENT AGREEMENT (the “Agreement”), is made and entered into effective as of May 22, 2023 (the
“Effective Date”), by and between G1 Therapeutics, Inc., a Delaware corporation (the “Company”), and Monica R. Thomas
(“Employee”).

1.

EMPLOYMENT; DUTIES. The Company agrees to employ Employee as its General Counsel, and Employee

agrees to accept such employment upon the terms and conditions hereinafter set forth. Employee will perform such services for
the Company as are customarily associated with such position and as may otherwise be assigned to the Employee from time to
time by the Company’s Chief Executive Officer or his designee. Employee will devote Employee’s full business time and
attention to the business and affairs of the Company, and will perform Employee’s duties diligently and to the best of Employee’s
ability, in compliance with the Company’s policies and procedures and the laws and regulations that apply to the Company’s
business.

2.

TERM; TERMINATION. Employee’s employment under this Agreement will commence on May 22, 2023 (the

“Start Date”) and will continue until terminated by either party. Employee’s employment with the Company is at-will, and either
party can terminate the employment relationship and/or this Agreement at any time, for any or no cause or reason, and with or
without prior notice, subject to the applicable terms of Section 4. Upon termination of Employee’s employment by either party
for any reason, Employee will resign Employee’s position(s), if any, as an officer or director of the Company, as a member of the
Company’s Board of Directors (the “Board”) and any Board committees, as well as any other positions Employee may hold with
or for the benefit of the Company and/or its affiliates.

3.

COMPENSATION. As compensation for the services to be rendered by Employee under this Agreement, the

Company will provide the following compensation and benefits during Employee’s employment hereunder.

“Base Salary”) at an annual rate of Four Hundred Thousand Dollars ($400,000), payable in equal installments in accordance
with the Company’s customary payroll practices as in effect from time to time. The Base Salary may be reviewed from time to
time by the Company and may be increased in the sole discretion of the Company. The Base Salary may also be decreased in
connection with any Company-wide decrease in executive compensation.

(b)

ANNUAL BONUS. Employee will be eligible to receive an annual calendar year bonus based upon

Employee’s and the Company’s achievement of certain individual and Company goals that will be set for Employee by the Board
or its designee (the “Annual Bonus”). The amount of the target Annual Bonus will be equal to forty percent (40%) of
Employee’s then-current Base Salary as of the date of the payment; provided that the actual amount of the Annual Bonus may be
greater or less than such target amount. The Board or its designee will have the sole discretion to set the applicable individual and
Company goals, to determine whether the goals have been met, and to determine the amount of the Annual Bonus. The Annual
Bonus for any given year, if any is earned, will be paid in accordance with, and subject to, the Company’s policies and procedures
in effect from

time to time. Employee must be employed by the Company on December 31 of the bonus year in order to receive the Annual
Bonus for that year.

One Hundred and Fifty Thousand (150,000) shares of the Company’s common stock (the “Options”) at a per share

inducement material to you joining the Company, pursuant to Rule 5635(c)(4) of the Nasdaq Listed Company Manual and
will be further subject to the terms of a stock option agreement as approved by the Board setting forth the exercise price,
vesting conditions and other restrictions. One fourth (1/4th) of the total number of such Options will vest on the first

consolidation with or into another entity such that the stockholders of the Company prior to such transaction do not or are
not expected to own a majority of the voting stock of the surviving entity, (ii) the sale or other disposition of all or
substantially all of the assets of the Company, or (iii) the sale or other disposition of greater than fifty percent (50%) of
the then-outstanding voting stock of the Company by the holders thereof to one or more persons or entities who are not
then stockholders of the Company.

(ii)    RESTRICTED STOCK UNITS. Effective on May 22, 2023, Employee will be granted Fifty

Thousand (50,000) restricted stock units (“RSUs”) with respect to the Company’s common stock. The RSUs will be

(100%) of any unvested RSUs will vest immediately if Employee’s employment is terminated by the Company without
Cause (as defined below) or Employee resigns with Good Reason (as defined below) within ninety (90) days following a
Change in Control (as defined above).

(d)

PAID TIME OFF. Employee will be eligible for paid time off in accordance with, and subject to, the

Company’s policies and procedures in effect from time to time.

(e)

BENEFITS. Employee will (subject to applicable eligibility requirements) receive such other benefits as

are provided from time to time to other similarly-situated employees of the Company pursuant to the Company’s policies and
procedures as they may be instituted from time to time. All such benefits are subject to the provisions of their respective plan
documents in accordance with their terms. Employee acknowledges and agrees that the Company has the unilateral right to

2

amend, modify or terminate its employee benefit plans or policies to the maximum extent allowed by law.

(f)

EXPENSE REIMBURSEMENT. The Company will reimburse Employee for all reasonable business
expenses incurred by Employee in connection with the performance of Employee’s duties hereunder, subject to Employee’s
compliance with the Company’s reimbursement policies in effect from time to time. All reimbursements provided under this
Agreement will be made or provided in accordance with the requirements of Section 409A of the Internal Revenue Code and the
rules and regulations thereunder including, where applicable, the requirement that (i) any reimbursement is for expenses incurred
during Employee’s lifetime (or during a shorter period of time specified in this Agreement); (ii) the amount of expenses eligible
for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other calendar year; (iii)
the reimbursement of an eligible expense shall be made no later than the last day of the calendar year following the year in which
the expense is incurred; and (iv) the right to reimbursement or in kind benefits is not subject to liquidation or exchange for
another benefit.

(g) WITHHOLDINGS. The Company will withhold from any amounts payable under this Agreement, such

federal, state and local taxes, as the Company reasonably determines are required to be withheld pursuant to applicable law.

(h)

Signing Bonus. The Company will pay Employee Fifteen Thousand Dollars ($15,000) (the “Signing
Bonus”) payment, minus applicable taxes and withholdings, in accordance with the Company's payroll practices on the first
payroll date after the Start Date. The Signing Bonus is provided as an advance and will be earned by Employee if Employee
remains employed with the Company for twelve (12) months from the Start date. If Employee resigns for any reason or is
terminated by the Company for “cause” within twelve (12) months from the Start Date, Employee agrees to pay back to the
Company the total amount of the advanced Signing Bonus within thirty (30) days of Employee’s separation date with the
Company. The Company may deduct any monies or portion thereof from amounts due to Employee, including final pay.

4.

EFFECT OF TERMINATION.

(a)

GENERALLY. When Employee’s employment with the Company is terminated for any reason, Employee,

or Employee’s estate, as the case may be, will be entitled to receive the compensation and benefits earned through the effective
date of termination, along with reimbursement for any approved business expenses that Employee has timely submitted for
reimbursement in accordance with the Company’s expense reimbursement policy or practice.

(b)

SEPARATION BENEFIT UPON CERTAIN TERMINATIONS. If the Company terminates Employee’s
employment without Cause (as defined below), or if Employee resigns Employee’s employment for Good Reason (as defined
below), then conditioned upon Employee executing a Release (as defined below) following such termination, Employee will be
entitled to receive an amount equal to payment of Employee’s then-current Base Salary for a period of twelve (12) months (the
“Separation Benefit”). The Separation Benefit is conditioned upon Employee executing a release of claims in a form satisfactory
to the Company (the “Release”) within the time specified therein, which Release is not revoked within any time period allowed
for revocation under applicable law. The Separation Benefit will be payable to Employee over time in accordance with the

3

Company’s payroll practices and procedures beginning on the sixtieth (60 ) day following the termination of Employee’s
employment with the Company, provided that the Company, in its sole discretion, may begin the payments earlier. For avoidance
of doubt, the termination of Employee’s employment as a result of Employee’s death or disability (meaning the inability of
Employee, due to the condition of Employee’s physical, mental or emotional health, effectively to perform the essential functions
of Employee’s job with or without reasonable accommodation for a continuous period of more than 90 days or for 90 days in any
period of 180 consecutive days, as determined by the Board in its sole discretion in consultation with a physician retained by the
Company) will not constitute a termination without Cause triggering the rights described in this Section 4(b).

th

(c)

CAUSE. For purposes of this Agreement, “Cause” means: (i) Employee’s fraud, embezzlement or
misappropriation with respect to the Company; (ii) Employee’s material breach of fiduciary duties to the Company; (iii)
Employee’s willful or negligent misconduct; (iv) Employee’s material breach of this Agreement; (v) Employee’s willful failure or
refusal to perform Employee’s material duties under this Agreement or failure to follow any specific lawful instructions of the
Company; (vi) Employee’s conviction or plea of nolo contendere in respect of a felony or of a misdemeanor involving moral
turpitude; (vii) Employee’s alcohol or substance abuse which has a material adverse effect on Employee’s ability to perform
Employee’s duties under this Agreement; or (viii) Employee’s engagement in a form of discrimination or harassment prohibited
by law (including, without limitation, discrimination or harassment based on race, color, religion, sex, national origin, age or
disability). In the event that the Company concludes that Employee has engaged in acts constituting Cause as defined in clause
(iii), (iv), (v), or (vii) above, prior to terminating this Agreement for Cause the Company will provide Employee with at least
fifteen (15) days’ advance written notice of the specific circumstances constituting such Cause, and an opportunity to correct
such circumstances.

(d)

GOOD REASON. In order for Employee to resign for Good Reason, Employee must provide written

notice to the Company of the existence of the Good Reason condition within thirty (30) days of the initial existence of such Good
Reason condition. Upon receipt of such notice, the Company will have thirty (30) days during which it may remedy the Good
Reason condition and not be required to provide for the benefits described in Section 4(b) above as a result of such proposed
resignation if successfully remedied. If the Good Reason condition is not remedied within such thirty (30) day period, Employee
may resign based on the Good Reason condition specified in the notice effective no later than thirty (30) days following the
expiration of the thirty (30) day cure period. For purposes of this Agreement, “Good Reason” means the occurrence of any of the
following events without Employee’s consent: (i) a material reduction of Employee’s Base Salary not generally applicable to
other executive-level employees of the Company, (ii) a material diminution of the Employee’s authority, duties, or
responsibilities, (iii) a relocation of Employee’s primary workplace to a location that is more than fifty (50) miles from the
location of Employee’s primary workplace as of the date hereof, or (iv) the Company’s material breach of this Agreement.

(e)

APPLICATION OF INTERNAL REVENUE CODE SECTION 409A. Notwithstanding anything to the

contrary set forth herein, any payments and benefits provided under this Section 4 that constitute “deferred compensation” within
the meaning of Section 409A of the Internal Revenue Code and the regulations and other guidance thereunder and any state law
of similar effect (collectively “Section 409A”) will not commence in connection with Employee’s termination of employment
unless and until Employee has also incurred a “separation from service” (as such term is defined in Treasury Regulation Section
1.409A-1(h) (a “Separation From Service”), unless the

4

Company reasonably determines that such amounts may be provided to Employee without causing Employee to incur an
additional tax under Section 409A. The parties intend that each installment of the Separation Benefits payments provided for in
this Agreement is a separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). For the avoidance of
doubt, the parties intend that payments of the Separation Benefits set forth in this Agreement satisfy, to the greatest extent
possible, the exemptions from the application of Section 409A provided under Treasury Regulation Sections 1.409A-1(b)(4),
1.409A-1(b)(5) and 1.409A-1(b)(9). However, if the Company determines that the Separation Benefits constitute “deferred
compensation” under Section 409A and Employee is, on the termination of service, a “specified employee” of the Company or
any successor entity thereto, as such term is defined in Section 409A, then, solely to the extent necessary to avoid the incurrence
of the adverse personal tax consequences under Section 409A, the timing of the Separation Benefits payments will be delayed
until the earlier to occur of: (i) the date that is six months and one day after Employee’s Separation From Service, or (ii) the date
of Employee’s death (such applicable date, the “Specified Employee Initial Payment Date”), the Company (or the successor
entity thereto, as applicable) will (A) pay to Employee a lump sum amount equal to the sum of the Separation Benefits payments
that Employee would otherwise have received through the Specified Employee Initial Payment Date if the commencement of the
payment of the Separation Benefits had not been so delayed pursuant to this Section and (B) commence paying the balance of the
Separation Benefits in accordance with the applicable payment schedules set forth in this Agreement.

(f)    NO FURTHER OBLIGATIONS. Except as expressly provided above or as otherwise required by law, the

Company will have no obligations to Employee in the event of the termination of this Agreement for any reason.

5.

EMPLOYEE REPRESENTATIONS. Employee represents and warrants that Employee is not obligated or

restricted under any agreement (including any non-competition or confidentiality agreement), judgment, decree, order or other
restraint of any kind that could impair Employee’s ability to perform the duties and obligations required of Employee hereunder.
Employee further agrees that Employee will not divulge to the Company any confidential information and/or trade secrets
belonging to others, including Employee’s former employers, nor will the Company seek to elicit from Employee such
information. Consistent with the foregoing, Employee will not provide to the Company, and the Company will not request, any
documents or copies of documents containing such information.

6.

NOTICES. Any notice required to be given hereunder will be sufficient if in writing and hand delivered or sent by
mail, return receipt requested, postage prepaid, in the case of Employee, to Employee’s address shown on the Company’s records,
and in the case of the Company, to 700 Park Offices Drive, Suite 200, Research Triangle Park, North Carolina 27709, or to such
other addresses as either party shall specify to the other.

7.

AMENDMENT; WAIVER. No amendment of any provision of this Agreement will be valid unless the

amendment is in writing and signed by the Company and Employee. No waiver of any provision of this Agreement will be valid
unless the waiver is in writing and signed by the waiving party. The failure of a party at any time to require performance of any
provision of this Agreement will not affect such party’s rights at a later time to enforce such provision. No waiver by a party of
any breach of this Agreement will be deemed to extend to any other breach hereunder or affect in any way any rights arising by
virtue of any other breach.

5

8.

GOVERNING LAW; VENUE. This Agreement will be governed by and construed in accordance with the laws of

the State of North Carolina, without regard to that body of law known as choice of law. The parties agree that any litigation
arising out of or related to this Agreement or Employee’s employment by the Company will be brought exclusively in any state
or federal court in Durham County, North Carolina. Each party (i) consents to the personal jurisdiction of said courts, (ii) waives
any venue or inconvenient forum defense to any proceeding maintained in such courts, and (iii) agrees not to bring any
proceeding arising out of or relating to this Agreement or Employee’s employment by the Company in any other court.

9.

BENEFIT. This Agreement will be binding upon and will inure to the benefit of each of the parties hereto, and to

their respective heirs, representatives, successors and permitted assigns. Employee may not assign any of Employee’s rights or
delegate any of Employee’s duties under this Agreement.

10.

ENTIRE AGREEMENT; OTHER AGREEMENTS. This Agreement contains the entire agreement and

understanding by and between the Company and Employee with respect to the subject matter hereof, and any representations,
promises, agreements or understandings, written or oral, not herein contained will be of no force or effect; provided, however,
that Employee is also subject to the terms and conditions of (i) that certain Employee Non-Competition and Non-Solicitation
Agreement by and between Employee and the Company, and (ii) that certain Employee Confidentiality and Inventions
Agreement by and between Employee and the Company, each of which remains in full force and effect.

11.

CAPTIONS; RULE OF CONSTRUCTION. The captions in this Agreement are for convenience only and in no

way define, bind or describe the scope or intent of this Agreement. The terms and provisions of this Agreement will not be
construed against the drafter or drafters hereof. All parties hereto agree that the language of this Agreement will be construed as a
whole according to its fair meaning and not strictly for or against any of the parties hereto.

COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which will be deemed

an original but all of which together will constitute one and the same agreement. Facsimile or PDF reproductions of original
signatures will be deemed binding for the purpose of the execution of this Agreement.

13.

SEVERABILITY. Each provision of this Agreement is severable from every other provision of this Agreement.

Any provision of this Agreement that is determined by any court of competent jurisdiction to be invalid or unenforceable will not
affect the validity or enforceability of any other provision. Any provision of this Agreement held invalid or unenforceable only in
part or degree will remain in full force and effect to the extent not held invalid or unenforceable.
