SUMMARY OF RISK FACTORS

Table of Contents

these  risk  factors,  the  risk  factors  described  in  Item  1A,  and  the  other  reports  and  documents  that  we  have  filed  with  the  Securities  and  Exchange
Commission (“SEC”).  

Risks Related to our Finances and Capital Requirements

● We have incurred significant losses since our inception and anticipate that we will incur continued losses for the foreseeable future. We have not
generated any sales revenue from our development stage products, and we do not know when, or if, we will generate any revenue from sales of an
approved product.

● Our short operating history makes it difficult to evaluate our business and prospects.

● Our  success  is  contingent  upon  raising  additional  capital  for  our  development  programs  and  commercialization  efforts,  which  may  fail.  Even  if
successful,  our  future  capital  raising  activities  may  dilute  our  current  stockholders,  restrict  our  operations,  or  require  us  to  relinquish  proprietary
rights.

● Our limited resources may cause us to fail to capitalize on programs or product candidates presenting commercial opportunity or high likelihood of

success.

Risks Pertaining to our Business Strategy, Structure and Organization

● Our future growth and success depend on our ability to successfully develop and commercialize our product candidates, which we have yet to do.

● Our future growth depends on our acquiring or in-licensing products or product candidates and integrating such products into our business.

Risks Inherent in Drug Development and Commercialization

● Because results of preclinical studies and early clinical trials are not necessarily predictive of future results, any product candidate we advance may
not have favorable results in later clinical trials.  Moreover, interim, “top-line,” and preliminary data from our clinical trials that we announce or
publish may change, or the perceived product profile may be impacted, as more patient data or additional endpoints are analyzed.  

● We may not receive the required regulatory approvals for any of our product candidates on our projected timelines, if at all, which may result in

increased costs and delay our ability to generate revenue.

●

If  a  product  candidate  demonstrates  lack  of  efficacy  or  adverse  side  effects,  we  may  need  to  abandon  or  limit  the  development  of  such  product
candidate.

● We  may  not  obtain  the  desired  labeling  claims  or  intended  uses  for  product  promotion,  or  favorable  scheduling  classifications,  to  successfully

promote our products.

●

Even if a product candidate is approved, it may be subject to various post-marketing requirements, including studies or clinical trials, and increased
regulatory scrutiny.

● Our  competitors  have  developed  or  may  develop  treatments  for  our  products’  target  indications,  which  could  limit  our  product  candidates’

commercial opportunity and profitability.

●

If our products are not broadly accepted by the healthcare community, the revenues from any such product will likely be limited.

● Any successful products liability claim related to any of our current or future product candidates may cause us to incur substantial liability and limit

the commercialization of such products.

Table of Contents

Risks Related to Reliance on Third Parties

● We rely, and will rely in the future, on third-party contract research organizations and contract manufacturers for the conduct of our preclinical and
clinical studies and trials, for the completion of commercial and pre-commercial manufacturing and, eventually, for commercialization. If such third
parties fail to perform contractual obligations, meet deadlines, comply with applicable regulations, or if our relationships with such third parties are
disrupted, our product candidates may be delayed, and our revenue potential may be limited.

● We rely on clinical data and results obtained by third parties, which may prove inaccurate or unreliable.

Risks Relating to Legislation and Regulation Affecting the Biopharmaceutical and Other Industries

● We operate in a heavily regulated industry, and we cannot predict the impact that any future legislation or administrative or executive action may

have on our operations.

● We may be subject to anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security and other healthcare laws
and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and
diminished profits and future earnings.

Risks Pertaining to Intellectual Property and Potential Disputes with Licensors Thereof

●

If  we  are  unable  to  maintain  sufficient  patent  protection  for  our  technology  and  products,  our  competitors  could  develop  and  commercialize
products similar or identical to ours, impairing our ability to successfully commercialize potential products.

● We or our licensors may be subject to costly and time-consuming litigation for infringement of third-party intellectual property rights or to enforce

our or our licensors’ patents.

● Any dispute with our licensors may affect our ability to develop or commercialize our product candidates.

Risks Relating to Our Platform and Data

● Our  business  and  operations  would  suffer  in  the  event  of  computer  system  failures,  cyber-attacks,  or  deficiencies  in  our  or  third  parties’

cybersecurity.

Risks Relating to Our Control by Fortress Biotech, Inc. (“Fortress”)

●

Fortress controls a voting majority of our common stock and has the right to receive significant share grants annually, which will result in dilution
of our other stockholders and could reduce the value of our common stock.

● We have entered into certain agreements with Fortress and may have received better terms from unaffiliated third parties.

Risks Related to Conflicts of Interest

●

The Chairman of our Board of Directors is also the Executive Chairman, President, and Chief Executive Officer of TG Therapeutics, Inc.(“TGTX”).
We have entered a collaboration agreement and a sublicense agreement with TGTX, and as a result, certain conflicts of interest may arise.

● We share certain directors with Fortress, which could create conflicts of interest between us and Fortress.

Item 1.     Business

OVERVIEW

PART I

We  are  a  clinical-stage  immunotherapy  and  targeted  oncology  company  focused  on  the  acquisition,  development  and  commercialization  of  novel
treatments for patients with solid tumor cancers. We are evaluating our lead antibody product candidate, cosibelimab, an anti-programmed death-ligand 1
(“PD-L1”) antibody licensed from the Dana-Farber Cancer Institute (“Dana-Farber”), in an ongoing global, open-label, multicohort Phase 1 clinical trial in
checkpoint  therapy-naïve  patients  with  selected  recurrent  or  metastatic  cancers,  including  ongoing  cohorts  in  locally  advanced  and  metastatic  cutaneous
squamous cell carcinoma (“CSCC”) intended to support one or more applications for marketing approval. In addition, we are evaluating our lead small-
molecule, targeted anti-cancer agent, olafertinib, a third-generation epidermal growth factor receptor (“EGFR”) inhibitor, as a potential new treatment for
patients with EGFR mutation-positive non-small cell lung cancer (“NSCLC”).

In January 2022, we announced topline results from a cohort of the registration-enabling Phase 1 clinical trial of cosibelimab administered as a fixed dose
of 800 mg every two weeks in patients with metastatic CSCC. The cohort met its primary endpoint, with cosibelimab demonstrating a confirmed objective
response rate (“ORR”) of 47.4% (95% CI: 36.0, 59.1) based on independent central review of 78 patients enrolled in the metastatic CSCC cohort using
Response Evaluation Criteria in Solid Tumors version 1.1 (“RECIST 1.1”).

In December 2021, we announced the initiation of our CONTERNO study, a global, open-label, multi-center, randomized Phase 3 trial of cosibelimab in
combination with pemetrexed and platinum chemotherapy for the first-line treatment of patients with NSCLC. The primary endpoint for the CONTERNO
Phase 3 trial is overall survival (“OS”), and key secondary endpoints include progression-free survival (“PFS”), ORR and safety.

We have also entered into various collaboration agreements with TG Therapeutics, Inc. (“TGTX”), a related party, to develop and commercialize certain
assets in connection with our licenses in the field of hematological malignancies, while we retain the right to develop and commercialize these assets in
solid tumors.

To date, we have not received approval for the sale of any product candidate in any market and, therefore, have not generated any product sales from any
product  candidates.  In  addition,  we  have  incurred  substantial  operating  losses  since  our  inception,  and  expect  to  continue  to  incur  significant  operating
losses for the foreseeable future and may never become profitable. As of December 31, 2021, we have an accumulated deficit of $199.9 million.

We are a majority-controlled subsidiary of Fortress Biotech, Inc. (“Fortress”).

PRODUCTS UNDER DEVELOPMENT

Immuno-Oncology Agents

Cosibelimab (Anti-PD-L1) Program

Cosibelimab (formerly referred to as CK-301) is a fully-human monoclonal antibody of IgG1 subtype that directly binds to PD-L1 and blocks the PD-L1
interaction with the Programmed Death Receptor-1 (“PD-1”) and B7.1 receptors. Cosibelimab’s primary mechanism of action is based on the inhibition of
the interaction between PD-L1 and its receptors PD-1 and B7.1, which removes the suppressive effects of PD-L1 on anti-tumor CD8+ T-cells to restore the
cytotoxic T cell response. Additionally, cosibelimab has a functional Fc domain that may be capable of inducing antibody-dependent cellular cytotoxicity
(“ADCC”) and complement-dependent cytotoxicity (“CDC”) against tumor cells.

Numerous preclinical and clinical studies of third-parties have demonstrated that antibodies that block the interaction of PD-1 with its ligands, PD-L1 and
PD-L2,  or  those  that  block  only  the  interaction  of  PD-L1  with  PD-1  can  augment  anti-tumor  T-cell  responses  and  lead  to  complete  and  lasting  tumor
eradication in a certain proportion of patients. Confirmed ORRs in the labels for the FDA approved PD-1 and PD-L1 blocking antibodies were cited in the
20-45% range based on clinical trials in patients with metastatic melanoma and NSCLC. Potent therapeutic anti-tumor responses due to blocking of PD-
1/PD-L1  interaction  have  been  demonstrated  by  these  approved  products  in  patients  with  various  solid  tumors  including,  but  not  limited  to,  NSCLC,
melanoma, RCC, head and neck cancer, CSCC and urothelial carcinoma.

We are developing cosibelimab in solid tumor oncology indications where studies of other PD-1/PD-L1 antibodies have shown to be effective. We licensed
the  exclusive  worldwide  rights  to  certain  anti-PD-L1  antibodies  from  Dana-Farber  in  March  2015.  Also  in  March  2015,  we  entered  into  a  Global
Collaboration Agreement with TGTX, a related party, to develop and commercialize anti-PD-L1 antibodies in the field of hematological malignancies. We
retain the right to develop and commercialize our anti-PD-L1 antibodies in solid tumors. We believe that cosibelimab has the potential to be effective in
many oncological indications as a monotherapy or in combination with other anti-tumor immune response potentiating compounds and targeted therapies.

We commenced a Phase 1 multi-center clinical study for cosibelimab in October 2017. The study is evaluating the safety and tolerability of ascending doses
of cosibelimab in checkpoint therapy-naïve patients with selected recurrent or metastatic cancers. Following completion of dose escalation in March 2018,
multiple  dose  expansion  cohorts  were  initiated,  including  ongoing  cohorts  in  locally  advanced  and  metastatic  CSCC,  intended  to  support  one  or  more
applications for marketing approval. The primary endpoint is ORR, and secondary endpoints include duration of response, PFS, and OS. In January 2022,
we  announced  topline  results  from  a  cohort  of  this  study  with  cosibelimab  administered  as  a  fixed  dose  of  800  mg  every  two  weeks  in  patients  with
metastatic  CSCC.  The  cohort  met  its  primary  endpoint,  with  cosibelimab  demonstrating  a  confirmed  ORR  of  47.4%  (95%  CI:  36.0,  59.1)  based  on
independent central review of 78 patients enrolled in the metastatic CSCC cohort using RECIST 1.1. Based on these results, Checkpoint intends to submit a
Biologics License Application (“BLA”) to the U.S. Food and Drug Administration (“FDA”) for cosibelimab in late 2022, to be followed by a marketing
authorization application (“MAA”) submission in Europe and additional potential submissions in markets worldwide.

We commenced our CONTERNO study, a global, randomized Phase 3 trial of cosibelimab in December 2021. The CONTERNO study is an open-label,
multi-center, randomized trial investigating cosibelimab combined with pemetrexed and investigator’s choice of platinum chemotherapy (either carboplatin
or cisplatin) versus pemetrexed and platinum chemotherapy alone in patients with previously untreated stage IV non-squamous NSCLC and with no EGFR
mutations  or ALK  translocations.  The  primary  endpoint  for  the  CONTERNO  Phase  3  trial  is  OS,  and  key  secondary  endpoints  include  PFS,  ORR  and
safety. The study is designed to potentially support full regulatory approvals worldwide.

CK-302 (Anti-GITR) Program

Our  anti-GITR  monoclonal  antibody,  CK-302,  is  a  fully  human  agonistic  antibody  that  is  designed  to  bind  to  and  trigger  signaling  in  GITR  expressing
cells. Scientific literature indicates that GITR is a co-stimulatory molecule of the TNF receptor family and is expressed

3

Table of Contents

on activated T cells, B cells, natural killer (“NK”) and regulatory T-cells (“Treg”). As a co-stimulatory molecule, GITR engagement increases proliferation,
activation,  and  cytokine  production  of  CD4+  and  CD8+  T-cells.  We  believe  our  anti-GITR  monoclonal  antibody  has  the  potential  to  abrogate
immunosuppressive activity of natural Treg on expansion of T-effector cells. GITR-specific agonistic monoclonal antibodies under development by third
parties  have  been  shown  to  induce  tumor  regression  in  vivo  through  the  activation  of  CD4+  T-cells,  CD8+  T-cells  and  NK  cells  in  a  number  of  tumor
models.

We  licensed  the  exclusive  worldwide  rights  to  anti-GITR  antibodies  from  Dana-Farber  in  March  2015. Also  in  March  2015,  we  entered  into  a  Global
Collaboration Agreement with TGTX to develop and commercialize anti-GITR antibodies in the field of hematological malignancies. We retain the right to
develop and commercialize anti-GITR antibodies in solid tumors. We believe that an anti-GITR antibody has the potential to be effective in one or more
oncological  indications  as  a  monotherapy  or  in  combination  with  an  anti-PD-L1  antibody  as  well  as  other  anti-tumor  immune  response  potentiating
compounds and targeted therapies.

Currently, we are in preclinical development for this program.

Targeted Anti-Cancer Agents

Olafertinib (also known as CK-101 and RX518) EGFR Inhibitor Program

We are developing olafertinib as an oral, third-generation, irreversible kinase inhibitor against selective mutations of EGFR. Activating mutations in the
tyrosine kinase domain of EGFR such as L858R and exon 19 deletion are found in approximately 20% of patients with advanced NSCLC. Compared to
chemotherapy, first-generation EGFR inhibitors significantly improved ORR and PFS in previously untreated NSCLC patients carrying EGFR mutations.
However, tumor progression could develop due to resistance mutations, often within months of treatment with first-generation EGFR inhibitors.

The  EGFR  T790M  “gatekeeper”  mutation  is  the  most  common  resistance  mutation  found  in  patients  treated  with  first-generation  EGFR  inhibitors.  The
mutation decreases the affinity of first-generation inhibitors to EGFR kinase domain, rendering the drugs ineffective. Second-generation EGFR inhibitors
have  improved  in  vitro  potency  against  the  T790M  mutation  but  have  not  provided  meaningful  benefits  in  NSCLC  patients  due  to  toxicity  from  also
inhibiting wild-type EGFR.

Third-generation EGFR inhibitors are designed to be highly selective against one or more EGFR activating mutations and the T790M resistance mutation
with minimal inhibition of wild-type EGFR, thereby potentially improving tolerability and safety profiles. In November 2015, Tagrisso® (osimertinib), a
third-generation  EGFR  inhibitor  developed  by AstraZeneca  plc,  received  accelerated  FDA  approval  for  the  treatment  of  patients  with  metastatic  EGFR
T790M mutation-positive NSCLC who have progressed on or after receiving EGFR tyrosine kinase inhibitor therapy. Tagrisso received full approval from
the  FDA  in  2017  based  on  data  from  a  randomized,  Phase  3  trial,  in  which  Tagrisso  significantly  improved  PFS  versus  platinum-based  doublet
chemotherapy, providing 10.1 months of median PFS compared to 4.4 months from chemotherapy. Subsequently, in April 2018, Tagrisso received FDA
approval for the first-line treatment of adult patients with metastatic NSCLC whose tumors have the EGFR exon 19 deletion or exon 21 L858R activating
mutations based on data from a randomized, Phase 3 trial in which Tagrisso significantly improved PFS versus first-generation EGFR inhibitors, providing
18.9 months of median PFS compared to 10.2 months from the EGFR inhibitor comparators, erlotinib or gefitinib.

We are developing olafertinib for the potential treatment of adult patients with metastatic NSCLC whose tumors have EGFR exon 19 deletion mutations.
We believe that olafertinib has the potential to be effective in this population as a monotherapy or in combination with other anti-tumor immune response
potentiating compounds.

In March 2015, Fortress entered into an exclusive license agreement with NeuPharma, Inc., which agreement was assigned to us by Fortress on the same
date, to develop and commercialize novel covalent third-generation EGFR inhibitors on a worldwide basis outside of certain Asian countries. In August
2016,  the  FDA  accepted  our  Investigational  New  Drug  application  (“IND”)  and  we  initiated  a  Phase  1  clinical  trial  in  September  2016.  The  trial  is
evaluating the safety and tolerability of ascending doses of olafertinib in patients with advanced solid tumors to determine the maximum tolerated dose and
the safety and efficacy of olafertinib in patients with EGFR mutation-positive NSCLC. In September 2018, we announced preliminary interim data in an
oral presentation at the International Association for the Study of Lung Cancer 19th World Conference on Lung Cancer in Toronto. In November 2020,
NeuPharma,  Inc.  commenced  a  Phase  3  clinical  trial  in  China  evaluating  olafertinib  in  treatment-naïve  locally  advanced  or  metastatic  NSCLC  patients
whose tumors have EGFR exon 19 deletion mutations. We have met with the FDA to discuss the adequacy of the ongoing Phase 3 trial in China.

CK-103 BET Inhibitor Program

We are developing CK-103, a novel, selective and potent small molecule inhibitor of bromodomain and extra-terminal (“BET”) bromodomains. CK-103
binds to the first and second bromodomains (BD1, BD2) of the BET protein family, BRD2, BRD3, BRD4, and BRDT. A bromodomain is an amino acid
protein  domain  that  recognizes  acetylated-lysine.  The  binding  of  the  drug  prevents  interaction  between  BET  proteins  and  both  acetylated  histones  and
transcription  factors.  Therefore,  BET  proteins,  such  as  BRD4,  are  considered  potential  therapeutic  targets  in  cancer,  as  they  may  play  a  pivotal  role  in
regulating the transcription of key regulators of cancer cell growth and survival, including the c-Myc oncogene. BRD4 is often required for expression of c-
Myc. Scientific literature has shown that small molecule inhibition of BET bromodomains may lead to selective killing of tumor cells across a broad range
of  hematologic  malignancies  and  certain  targeted  solid  tumors.  We  plan  to  develop  CK-103  for  the  treatment  of  various  advanced  and  metastatic  solid
tumor cancers, including, but not limited to, those associated with elevated c-Myc expression.

In May 2016, we entered into an exclusive license agreement with Jubilant Biosys Limited to develop and commercialize novel compounds that inhibit BET
bromodomains on a worldwide basis. Also in May 2016, we entered into a Sublicense Agreement with TGTX to develop and commercialize CK-103 in the
field of hematological malignancies. We retain the right to develop and commercialize CK-103 in solid tumors. Currently, we have completed the required
CMC, pharmacology and toxicology activities that we believe will support an IND application filing.

Anti-CAIX Research Program

Our anti-carbonic anhydrase IX (“CAIX”) antibody is a fully human preclinical antibody designed to recognize CAIX expressing cells and kill them via
ADCC and CDC. Scientific literature indicates that CAIX is a well characterized tumor associated antigen with expression almost exclusively limited to the
cells of renal cell carcinoma (“RCC”). More than 85% of RCC cases have been demonstrated to express high levels of CAIX expression. There is very
limited expression of this antigen on healthy tissue which we believe will limit reactivity of this antibody against healthy tissues.

In  2015,  preclinical  data  were  published  in  the  peer-reviewed  journal,  Molecular  Cancer,  that  demonstrated  that  our  anti-CAIX  antibodies  could  trigger
killing  of  CAIX-positive  human  RCC  cell  lines  in  tissue  culture  via ADCC  and  CDC.  The  killing  activity  correlated  positively  with  the  level  of  CAIX
expression  on  RCC  tumor  cell  lines.  In  addition,  the  study  demonstrated  that  our  anti-CAIX  antibodies  inhibited  growth  of  CAIX-positive  tumors  in  a
mouse xenograft model as well as led to the activation of T-cells and NK cells.

We licensed the exclusive worldwide rights to certain anti-CAIX antibodies from Dana-Farber in March 2015. Currently, we are in preclinical development
for this program.

Completion  dates  and  costs  in  the  above  table  are  estimates  due  to  the  uncertainties  associated  with  clinical  trials  and  the  related  requirements  of
development. In the cases where the requirements for clinical trials and development programs have not been fully defined, or are dependent on the success
of other trials, we cannot estimate trial completion or cost with any certainty. The actual spending on each trial during the year is also dependent on funding.

INTELLECTUAL PROPERTY AND PATENTS

General

Our goal is to obtain, maintain and enforce patent protection for our products, formulations, processes, methods and other proprietary technologies, preserve
our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the United States and in other countries. Our policy is to
actively  seek  to  obtain,  where  appropriate,  broad  intellectual  property  protection  for  our  product  candidates,  proprietary  information  and  proprietary
technology through a combination of contractual arrangements and patents, both in the U.S. and elsewhere in the world.

We also depend upon the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors, consultants and other
contractors  (“know-how”).  To  help  protect  our  proprietary  know-how  which  is  not  patentable,  and  for  inventions  for  which  patents  may  be  difficult  to
enforce,  we  rely  on  trade  secret  protection  and  confidentiality  agreements  to  protect  our  interests.  To  this  end,  we  require  all  employees,  consultants,
advisors and other contractors to enter into confidentiality agreements that prohibit the disclosure of confidential information and, where applicable, require
disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

Patents  and  other  proprietary  rights  are  crucial  to  the  development  of  our  business.  We  will  be  able  to  protect  our  proprietary  technologies  from
unauthorized  use  by  third  parties  only  to  the  extent  that  our  proprietary  rights  are  covered  by  valid  and  enforceable  patents,  supported  by  regulatory
exclusivity,  or  are  effectively  maintained  as  trade  secrets.  We  cannot  guarantee  the  scope  of  protection  of  the  issued  patents,  or  that  such  patents  will
survive a validity or enforceability challenge, or that any of the pending patent applications will issue as patents.

Generally,  patent  applications  in  the  U.S.  are  maintained  in  secrecy  for  a  period  of  18  months  or  more.  The  patent  positions  of  biotechnology  and
pharmaceutical companies are highly uncertain and involve complex legal and factual questions. Therefore, we cannot predict the breadth of claims allowed
in biotechnology and pharmaceutical patents, the continued patent eligibility of certain subject matter, or their enforceability. To date, there has been no
consistent policy regarding the breadth of claims allowed in biotechnology patents. Third parties or competitors may challenge or circumvent our patents or
patent applications, if issued. If our competitors prepare and file patent applications in the U.S. that claim technology also claimed by us, we may have to
participate in interference or derivation proceedings declared by the U.S. Patent and Trademark Office to determine priority of invention or inventorship,
which could result in substantial cost, even if the eventual outcome is favorable to us. Because of the extensive time required for development, testing and
regulatory  review  of  a  potential  product,  it  is  possible  that  before  we  commercialize  any  of  our  products,  any  related  patent  may  expire  or  remain  in
existence for only a short period following commercialization, thus reducing any advantage of the patent. However, the life of a patent covering a product
that has been subject to regulatory approval may have the ability to be extended through the patent restoration program, although any such extension could
still be minimal and, in any case, is limited to a maximum of five additional years of patent term.  But that maximum of five additional years is, itself,
subject to a cap of a maximum of 14 years of patent protection from the date of marketing approval.

In  March  2015,  we  licensed  intellectual  property  related  to  certain  antibodies  from  Dana-Farber.  The  intellectual  property  includes  issued  patents  in  a
number of countries, including the United States and Europe, as well as pending patent applications in several countries elsewhere. The issued patents and
pending patent applications relate generally to compositions and methods of treatment involving antibodies against PD-L1, CAIX, and GITR.

The PD-L1 segment of the portfolio includes two granted U.S. patents (U.S. Patent Nos. 9,828,434 and 10,604,581) directed to antibodies that bind to PD-
L1 and methods of augmenting a patient’s immune response by administering an anti-PD-L1 antibody, respectively. The ‘434 patent is scheduled to expire
October 4, 2033, and the ‘581 patent is scheduled to expire November 18, 2033, not including any patent term restorations, which might become available
under the provisions of U.S. patent laws, based on regulatory delays associated with obtaining marketing approval. Two Australian (AU 2013326901 and
2018226425), one Japanese (JP 6461800), one South Korean (KR 101947702), one Israeli (IL 237737), one Mexican (MX 370848), one Colombian (CO
34878), one Canadian

(CA 2886433), and two Chinese (CN 104994873 and CN 10782719) counterpart patents have issued, and additional international counterpart applications
are  pending  in  Canada,  China,  Europe  and  Hong  Kong.  The  issued  international  patents  and  any  patents  maturing  from  these  pending  applications  will
expire  no  sooner  than  October  2033.  In  June  2016,  Checkpoint  also  filed  a  company-owned  U.S.  provisional  application  (U.S.  62/356,105)  directed  to
antibodies and functional fragments thereof that bind to human PD-L1, and methods of inhibiting tumor cell proliferation in patients using such antibodies
or functional fragments. The provisional application was converted into a PCT application (PCT/US2017/039810) in June 2017, and a U.S. non-provisional
application  (U.S. Appl.  No.  15/636,610)  was  filed  at  the  same  time.  The  ’610  application  has  now  issued  as  U.S.  Patent  No.  10,590,199  with  claims
directed to specific anti-PD-L1 antibodies and fragments thereof, as well as methods of treating tumors/cancers with anti-PD-L1 antibodies and fragments
thereof.    The  ’199  patent  is  scheduled  to  expire  on  May  31,  2038,  not  including  any  patent  term  restorations,  which  might  become  available  under  the
provisions  of  U.S.  patent  laws,  based  on  regulatory  delays  associated  with  obtaining  marketing  approval. A  further  U.S.  application,  U.S. Appl.  No.
16/818,621,  was  filed  before  the  issuance  of  the  ‘199  patent  and  is  currently  pending. An  Israeli  counterpart  patent  has  also  granted  (IL  263611),  and
additional national stage applications are pending in Australia, Brazil, Canada, China, Europe, Hong Kong, Israel, India, Japan, South Korea, Mexico, New
Zealand, Russia, Singapore and Thailand. Any patents maturing from these pending applications will expire no sooner than June 2037.

The CAIX segment of the portfolio includes three granted U.S. patents (U.S. Patent Nos. 8,466,263, 10,450,383, and 11,174,323) and one pending U.S.
application  (U.S. Appl.  No.  17/498,582).  The  ‘263  patent  is  directed  to  isolated  human  monoclonal  antibodies  and  scFv  antibodies  that  bind  to  CAIX
(G250)  protein,  and  compositions  and  kits  comprising  such  antibodies.  The  term  of  the  ‘263  patent  runs  to  July  9,  2029.  The  ‘383  patent  is  directed  to
methods of treating cancer with anti-CAIX antibodies, and its term runs until April 28, 2027. The ‘323 patent is directed to methods of treating renal cancer
with anti-CAIX antibodies, and its term runs until February 11, 2027. The ‘263 patent, the ‘383 patent, the ‘323 patent, and any patent issuing from the
‘867 application may be entitled to any patent term restorations that might become available under the provisions of U.S. patent laws, based on regulatory
delays associated with obtaining marketing approval. The European counterpart patent (EP 1979379) is in force in Switzerland, Liechtenstein, Germany,
France and the United Kingdom. A Canadian counterpart patent (CA 2,632,094) has also been issued. Both the European and Canadian counterpart patents,
as well as any pending applications outside the United States, are scheduled to expire no sooner than December 2026.

The GITR segment of the portfolio includes an International Application No. PCT/US2015/054010, filed in October 2015, and International Application
No. PCT/US2017/043504, filed in July 2017. All of the national stage applications claiming priority to PCT/US2015/054010 have lapsed; however, there is
one  granted  patent  (U.S.  Patent  No.  10,463,732)  in  this  family.  The  ‘732  patent  will  not  expire  until  at  least  October  2035,  barring  any  patent  term
restorations that might become available under the provisions of U.S. patent laws. National stage applications claiming priority to PCT/US2017/043504 are
pending in the U.S. (U.S. Appl. No. 16/319,590), Australia, Brazil, Canada, China, Europe, Israel, Japan, South Korea, Singapore, Russian, New Zealand
and Mexico. Any of these national stage applications that issue or grant as patents (including U.S. Application No. 16/319,590) would expire no earlier than
July 2037. One U.S. patent (U.S. 11,046,777) has issued in the patent family claiming priority to PCT/UC2017/043504, and this U.S. patent will not expire
until at least July 2037, barring any patent term restorations that might become available under the provisions of the U.S. patent laws.

In March 2015, Fortress in-licensed intellectual property from NeuPharma, assigned to us by Fortress on the same date, which is directed to technology
involving small molecules that are inhibitors of EGFR and kinase mutants, including the compound olafertinib. EGFR is a receptor tyrosine kinase of the
ErbB  family  and  is  also  known  as  “Her1”  and  “ErbB1.”  The  in-licensed  patent  estate  includes  four  granted  U.S.  patents,  a  granted  European  patent,  a
granted patent in Hong Kong, a granted patent in Singapore, a granted patent in the Philippines, a granted Japanese patent, a granted South Korean patent, a
granted  Malaysian  patent,  two  granted Australian  patents,  a  granted  New  Zealand  patent,  two  granted  Israeli  patents,  a  granted  Mexican  patent  and  a
granted  Russian  patent.  U.S.  Patent  No.  9,550,770  is  directed  to  a  generic  formula  of  small  molecules  and  also  has  a  specific  claim  directed  to  the
compound,  olafertinib.  The  granted  claims  also  cover  pharmaceutically  acceptable  salts,  pharmaceutical  compositions,  particular  dosage  forms  and
packaged  goods.  U.S.  Patent  No.  9,849,139  is  directed  to  methods  of  inhibiting  EGFR  or  an  EGFR  mutant  in  a  subject  in  need  thereof,  comprising
administering a therapeutically effective amount of the compounds of the ‘770 patent, including the compound, olafertinib. U.S. Patent No. 10,172,868 is
directed  to  methods  of  treating  non-small  cell  lung  cancer  with  a  specific  list  of  compounds,  including  the  compound,  olafertinib.  U.S.  Patent  No.
10,653,701 is directed to methods of treating skin cancer or lung cancer with a substituted quinazoline compound comprising an electrophilic group capable
of forming a covalent bond with a nucleophile, which includes the compounds of the ‘868 patent (e.g., the compound, olafertinib). Additionally, there is a
pending U.S. application in this family (U.S. Appl. No. 16/843,610) that was recently allowed, but has not yet issued, a further pending U.S. application
(U.S. Appl. No. 17/681,387) has been filed. The granted foreign patents cover the compound, olafertinib, and a broad range of related compounds, salts,
pharmaceutical

compositions, including various dosage forms of such pharmaceutical compositions and certain uses of such compounds or salts thereof in treating cancer,
a disorder mediated by EGFR, or NSCLC, either alone or in combination with an additional anti-cancer and/or cytotoxic agent. The term of granted U.S.
and foreign patents runs to August 22, 2034, not including any patent term restorations in the U.S., which might become available under the provisions of
U.S. patent laws, based on regulatory delays associated with obtaining marketing approval. Additional counterpart applications exist in jurisdictions around
the  world,  including, Australia,  Canada,  Hong  Kong,  the  Philippines,  Singapore,  South  Korea,  Malaysia,  Brazil,  India,  China  and  Europe. Any  patents
maturing from these pending applications would be scheduled to expire no sooner than August 2034. Checkpoint has also licensed from NeuPharma an
additional international application, PCT/US2019/017117, which was filed on February 7, 2019, and it directed to additional EGFR inhibitors and methods
of using the same. National stage applications claiming priority to PCT/US2019/017117 are pending in the U.S. (U.S. Appl. No. 16/967,696), Australia,
Canada, China, Europe, Hong Kong, the Philippines, Israel, Japan, South Korea, Singapore and New Zealand. Any of these national stage applications that
issue or grant as patents (including U.S. Application No. 16/967,696) would expire no earlier than February 2039.

In May 2016, we in-licensed intellectual property from Jubilant. Under the terms of the license agreement, Jubilant granted us exclusive, worldwide rights
under Jubilant’s patents and know-how covering small molecule inhibitors of BET, specifically targeting BRD4, a member of the BET family, which is
often  required  for  the  expression  of  c-Myc.  The  in-licensed  patent  estate  includes  two  international  (PCT)  applications,  filed  in  March  2016
(PCT/IN2016/050098)  and  September  2016  (PCT/IN2016/050300),  respectively,  which  claim  the  benefit  of  two  earlier-filed  Indian  provisional
applications. This patent estate has three granted U.S. patents, a granted Indian patent, two granted Japanese patents, two granted Australian patents, two
granted Russian patents, a granted Israeli patent, two granted patents in Hong Kong, two granted Chinese patents, two granted Mexican patents, and two
granted  European  patents  that  have  each  been  validated  across  a  broad  range  of  European  countries.  National  stage  applications  claiming  priority  to
PCT/IN2016/050098 or PCT/IN2016/050300 are pending in Brazil, Canada, Israel, India, South Korea, New Zealand, Thailand and the U.S. U.S. Patent
No.  10,689,390,  which  is  the  U.S.  national  phase  entry  of  PCT/IN2016/050098,  is  directed  to  a  generic  formula  of  small  molecule  BET  inhibitors  and
specifically claims exemplified small molecule BET inhibitors. The granted claims of the ‘390 patent also cover pharmaceutical compositions. Pending U.S.
Application (U.S. Appl. No.16/869,517) is directed to methods of treatment with the compounds claimed in the ‘390 patent, including inhibiting one or
more BET family bromodomains in the cell and treating a condition mediated by one or more BET family bromodomains. U.S. Patent No. 10,689,395,
which  is  the  U.S.  national  phase  entry  of  PCT/IN2016/050300,  is  directed  to  a  generic  formula  of  small  molecule  BET  inhibitors  that  cover  half  of  the
exemplified  small  molecule  BET  inhibitors  disclosed  in  PCT/IN2016/050300.  The  granted  claims  of  the  ‘395  patent  also  cover  pharmaceutical
compositions and a method of treating cancer. U.S. Patent No. 11,267,820, which is a continuation of the ‘395 patent, is directed to the remaining half of the
exemplified compounds disclosed in PCT/IN2016/050300 and has claims similar to those granted from the ‘395 patent. Any patents maturing from this
patent estate are expected to expire in 2036.

Other Intellectual Property Rights

We  depend  upon  trademarks,  trade  secrets,  know-how  and  continuing  technological  advances  to  develop  and  maintain  our  competitive  position.  To
maintain the confidentiality of trade secrets and proprietary information, we require our employees, scientific advisors, consultants and collaborators, upon
commencement  of  a  relationship  with  us,  to  execute  confidentiality  agreements  and,  in  the  case  of  parties  other  than  our  research  and  development
collaborators, to agree to assign their inventions to us. These agreements are designed to protect our proprietary information and to grant us ownership of
technologies that are developed in connection with their relationship with us. These agreements may not, however, provide protection for our trade secrets
in the event of unauthorized disclosure of such information.

In  addition  to  patent  protection,  we  may  utilize  orphan  drug  designation  or  other  provisions  of  the  Food,  Drug  and  Cosmetic Act  of  1938,  as  amended
(“FDCA”),  to  provide  market  exclusivity  for  certain  of  our  product  candidates.  Orphan  drug  regulations  provide  incentives  to  pharmaceutical  and
biotechnology companies to develop and manufacture drugs for the treatment of rare diseases, currently defined as diseases that exist in fewer than 200,000
individuals in the U.S., or, diseases that affect more than 200,000 individuals in the U.S. but that the sponsor does not realistically anticipate will generate a
net  profit.  Under  these  provisions,  a  manufacturer  of  a  designated  orphan  drug  can  seek  tax  benefits,  and  the  holder  of  the  first  FDA  approval  of  a
designated orphan drug product will be granted a seven-year period of marketing exclusivity for such FDA-approved orphan drug product. In September
2017, we received FDA Orphan Drug Designation for olafertinib for the treatment of EGFR mutation-positive NSCLC.

LICENSING AGREEMENTS AND COLLABORATIONS

Dana-Farber Cancer Institute, Inc.

In  March  2015,  we  entered  into  a  license  agreement  with  Dana-Farber,  which  license  was  amended  effective  on  October  5,  2015, April  12,  2016,  and
October 24, 2016, for an exclusive, worldwide license to Dana-Farber’s patents for a portfolio of fully human immuno-oncology targeted antibodies. The
field of use license includes all prophylactic, therapeutic or diagnostic uses in humans or animals excluding use in chimeric antigen receptor technology.
The Dana-Farber antibodies were generated in the laboratory of Dr. Wayne Marasco, MD, PhD, a Professor in the Department of Cancer Immunology and
AIDS at Dana-Farber. Under the terms of the agreement, we paid Dana-Farber an up-front licensing fee of $1.0 million and, on May 11, 2015, granted
Dana-Farber  five  percent  of  our  common  stock  on  a  fully-diluted  basis,  equal  to  500,000  shares  valued  at  $32,500  or  $0.065  per  share.  The  agreement
included an anti-dilution clause that maintained Dana-Farber’s ownership at 5% until such time that we raised $10 million in cash in exchange for common
shares.  Pursuant  to  this  provision,  on  September  30,  2015,  we  granted  to  Dana-Farber  an  additional  136,830  shares  of  common  stock  valued  at
approximately  $0.6  million  and  the  anti-dilution  clause  thereafter  expired.  Dana-Farber  is  eligible  to  receive  payments  of  up  to  an  aggregate  of
approximately $21.5 million for each licensed product upon our successful achievement of certain clinical development, regulatory and first commercial
sale  milestones.  In  addition,  Dana-Farber  is  eligible  to  receive  up  to  an  aggregate  of  $60.0  million  upon  our  successful  achievement  of  certain  sales
milestones based on aggregate net sales, in addition to royalty payments based on a tiered low to mid-single digit percentage of net sales. Dana-Farber also
receives an annual license maintenance fee of $50,000, which is creditable against milestone payments or royalties due to Dana-Farber. The portfolio of
antibodies  licensed  from  Dana-Farber  include  antibodies  targeting  PD-L1,  GITR  and  CAIX.  The  license  will  terminate  on  a  country-by-country  and
product-by-product basis until the royalty term in such country with respect to such product expires, at which time the agreement will expire in its entirety
with respect to such product in such country. The royalty term, on a product-by-product and country-by-country basis, is the later of (i) ten years after first
commercial sale of a given product in such country, or (ii) the expiration of the last-to-expire Dana-Farber patent containing a valid claim to the product in
such country. To date, we have incurred $6.2 million of upfront licensing and milestone payments under this license agreement.

In connection with the license agreement with Dana-Farber, in March 2015 we entered into a collaboration agreement with TGTX, which was amended and
restated in June 2019, to develop and commercialize the anti-PD-L1 and anti-GITR antibody research programs in the field of hematological malignancies.
We retain the right to develop and commercialize these antibodies in solid tumors. Michael Weiss, Chairman of the Board of Directors of Checkpoint and
Fortress’ Executive Vice Chairman, Strategic Development, is also the Executive Chairman, President and Chief Executive Officer and a stockholder of
TGTX. Under the terms of the original collaboration agreement, TGTX paid us $0.5 million, representing an upfront licensing fee. Upon the signing of the
amended  and  restated  collaboration  agreement  in  June  2019,  TGTX  paid  us  an  additional  $1.0  million  upfront  licensing  fee.  We  are  eligible  to  receive
substantive  potential  milestone  payments  for  the  anti-PD-L1  program  of  up  to  an  aggregate  of  approximately  $27.6  million  upon  TGTX’s  successful
achievement of certain clinical development, regulatory and first commercial sale milestones. This is comprised of up to approximately $8.4 million upon
TGTX’s  successful  completion  of  clinical  development  milestones,  and  up  to  approximately  $19.2  million  upon  regulatory  filings  and  first  commercial
sales  in  specified  territories.  We  are  also  eligible  to  receive  substantive  potential  milestone  payments  for  the  anti-GITR  antibody  program  of  up  to  an
aggregate  of  approximately  $21.5  million  upon  TGTX’s  successful  achievement  of  certain  clinical  development,  regulatory  and  first  commercial  sale
milestones.  This  is  comprised  of  up  to  approximately  $7.0  million  upon  TGTX’s  successful  completion  of  clinical  development  milestones,  and  up  to
approximately $14.5 million upon first commercial sales in specified territories. In addition, we are eligible to receive up to an aggregate of $60.0 million
upon TGTX’s successful achievement of certain sales milestones based on aggregate net sales for both programs, in addition to royalty payments based on a
tiered  low  double-digit  percentage  of  net  sales.  We  also  receive  an  annual  license  maintenance  fee,  which  is  creditable  against  milestone  payments  or
royalties due to us. TGTX also pays us for our out-of-pocket costs of material used by TGTX for their development activities. The collaboration agreement
will terminate on a product-by-product and country-by-country basis upon the expiration of the last licensed patent right, unless the agreement is earlier
terminated. For the years ended December 31, 2021 and 2020, we recognized approximately $0.2 million and $1.0 million respectively, in revenue from
our collaboration agreement with TGTX in the Statements of Operations. The year ended December 31, 2020 included a milestone payment of $925,000
upon the 12th patient dosed in a phase 1 clinical trial for the anti-PD-L1 antibody cosibelimab during March 2020.

Adimab, LLC

In October 2015, Fortress entered into a collaboration agreement with Adimab to discover and optimize antibodies using their proprietary core technology
platform. Under this agreement, Adimab optimized cosibelimab (formerly referred to as CK-301), our anti-PD-L1

Table of Contents

antibody which we originally licensed from Dana-Farber. In January 2019, Fortress transferred the rights to the optimized antibody to us, and we entered
into a collaboration agreement directly with Adimab on the same day. Under the terms of the agreement, Adimab is eligible to receive payments up to an
aggregate of approximately $7.1 million upon our successful achievement of certain clinical development and regulatory milestones, of which $4.8 million
are due upon various filings for regulatory approvals to commercialize the product. In addition, Adimab is eligible to receive royalty payments based on a
tiered low single digit percentage of net sales. The license will terminate on a country-by-country and product-by-product basis until the royalty term in
such  country  with  respect  to  such  product  expires,  at  which  time  the  agreement  will  expire  in  its  entirety  with  respect  to  such  licensed  product  in  such
country. The royalty term, on a product-by-product and country-by-country basis, begins on the first commercial sale of a product in a country and ends on
the  later  of  (a)  expiry  of  the  last-to-expire  licensor  patent  containing  a  valid  claim  to  the  compound  in  such  country;  or  (b)  twelve  years  after  the  first
commercial sale of such licensed product in such country. To date, we have incurred $3.7 million in milestone payments under our collaboration agreement
with Adimab.

NeuPharma, Inc.

In  March  2015,  Fortress  entered  into  an  exclusive  license  agreement  with  NeuPharma  to  develop  and  commercialize  novel  irreversible,  3rd  generation
EGFR inhibitors, including olafertinib, on a worldwide basis other than certain Asian countries. On the same date, Fortress assigned all of its right and
interest  in  the  EGFR  inhibitors  to  us.  The  license  agreement  was  amended  on  February  21,  2017.  Under  the  terms  of  the  license  agreement,  we  paid
NeuPharma an up-front licensing fee of $1.0 million, and NeuPharma is eligible to receive payments of up to an aggregate of approximately $40.0 million
upon our successful achievement of certain clinical development and regulatory milestones in up to three indications, of which $22.5 million are due upon
various regulatory approvals to commercialize the products. In addition, NeuPharma is eligible to receive payments of up to an aggregate of $40.0 million
upon our successful achievement of certain sales milestones based on aggregate net sales, in addition to royalty payments based on a tiered mid to high-
single digit percentage of net sales. The license will terminate on a country-by-country and product-by-product basis until the royalty term in such country
with respect to  such  product  expires,  at  which  time  the  agreement  will  expire  in  its  entirety  with  respect  to  such  product  in  such  country.  Royalty  term
means, on a licensed product-by-licensed product and country-by-country basis, the period from the first commercial sale of a given licensed product in
such  country  until  the  later  of  (a)  expiry  of  the  last-to-expire  licensor  patent  containing  a  valid  claim  to  the  compound  in  such  country;  or  (b)  the  10th
anniversary of the first commercial sale of such licensed product in such country. In a country where no licensor patent containing a valid claim with respect
to the compound has ever existed nor ever exists, the royalty term means on a product-by-product and country-by-country basis, the period from the first
commercial sale of such product in such country until the 10th anniversary of such first commercial sale of such product in such country. To date, we have
incurred $2.0 million of upfront licensing and milestone payments under the license agreement.

Jubilant Biosys Limited

In May 2016, we entered into a license agreement with Jubilant for an exclusive, worldwide license to Jubilant’s family of patents covering compounds that
inhibit BET proteins such as BRD4, including CK-103. The license agreement was amended on December 13, 2016 and March 31, 2017. Under the terms
of  the  license  agreement,  we  paid  Jubilant  an  up-front  licensing  fee  of  $2.0  million,  and  Jubilant  is  eligible  to  receive  payments  up  to  an  aggregate  of
approximately $89.0 million upon our successful achievement of certain clinical development and regulatory milestones, of which $59.5 million are due
upon various regulatory approvals to commercialize the products. In addition, Jubilant is eligible to receive payments up to an aggregate of $89.0 million
upon our successful achievement of certain sales milestones based on aggregate net sales, in addition to royalty payments based on a tiered low to mid-
single digit percentage of net sales. The license will terminate on a country-by-country and product-by-product basis until the royalty term in such country
with  respect  to  such  product  expires,  at  which  time  the  agreement  will  expire  in  its  entirety  with  respect  to  such  licensed  product  in  such  country.  The
royalty term, on a product-by-product and country-by-country basis, begins on the first commercial sale of a product in a country and ends on the expiration
of the last-to-expire Jubilant patent containing a valid claim to the product in such country. To date, we have incurred $2.4 million of upfront licensing and
milestone payments under the license agreement.

In connection with the license agreement with Jubilant, we entered into a sublicense agreement with TGTX, a related party, to develop and commercialize
the compounds licensed in the field of hematological malignancies, while we retain the right to develop and commercialize these compounds in the field of
solid tumors. Under the terms of the sublicense agreement, TGTX paid us $1.0 million, representing an upfront licensing fee, and we are eligible to receive
substantive potential milestone payments up to an aggregate of approximately $87.2 million upon TGTX’s successful achievement of clinical development
and  regulatory  milestones.  This  is  comprised  of  up  to  approximately  $25.5  million  upon  TGTX’s  successful  completion  of  three  clinical  development
milestones for two licensed products, and up to approximately $61.7 million upon the achievement of five regulatory approvals and first commercial sales
in

10

specified territories for two licensed products. In addition, we are eligible to receive potential milestone payments up to an aggregate of $89.0 million upon
TGTX’s  successful  achievement  of  certain  sales  milestones  based  on  aggregate  net  sales  by  TGTX,  for  two  licensed  products,  in  addition  to  royalty
payments based on a mid-single digit percentage of net sales by TGTX. TGTX also pays us for 50% of IND enabling costs and patent expenses. For each of
the years ended December 31, 2021 and 2020, we recognized approximately $0.1 million in revenue related to the sublicense agreement in the Statements
of Operations.

COMPETITION

Competition  in  the  pharmaceutical  and  biotechnology  industries  is  intense.  Our  competitors  include  pharmaceutical  companies  and  biotechnology
companies, as well as universities and public and private research institutions. In addition, companies that are active in different but related fields represent
substantial competition for us. Many of our competitors have significantly greater capital resources, larger research and development staffs and facilities
and  greater  experience  in  drug  development,  regulation,  manufacturing  and  marketing  than  we  do.  These  organizations  also  compete  with  us  to  recruit
qualified  personnel,  attract  partners  for  joint  ventures  or  other  collaborations,  and  license  technologies  that  are  competitive  with  ours.  To  compete
successfully  in  this  industry,  we  must  identify  novel  and  unique  drugs  or  methods  of  treatment  and  then  complete  the  development  of  those  drugs  as
treatments.

The  drugs  that  we  are  attempting  to  develop  will  have  to  compete  with  existing  therapies.  In  addition,  a  large  number  of  companies  are  pursuing  the
development  of  pharmaceuticals  that  target  the  same  conditions  that  we  are  targeting.  Other  companies  have  products  or  product  candidates  in  various
stages of preclinical or clinical development, or with marketing approvals, to treat conditions for which we are also seeking to discover and develop product
candidates. Some of these potential competing drugs are further advanced in development than our product candidates and may be commercialized earlier.

In the immuno-oncology area, almost every major pharmaceutical company has a PD-1 and/or PD-L1 antibody in clinical development or on the market,
including, without limitation, Merck & Co. (approved drug PD-1 with the brand name Keytruda®), Bristol-Myers Squibb (approved PD-1 with the brand
name Opdivo®), Roche (approved PD-L1 with the brand name Tecentriq®), AstraZeneca (approved PD-L1 with the brand name Imfinzi®), Pfizer/Merck
KGA (approved PD-L1 with the brand name Bavencio®), Regeneron (approved PD-1 with the brand name Libtayo®) and GlaxoSmithKline (approved PD-
1  with  the  brand  name  Jemperli®).  We  are  aware  of  several  anti-GITR  antibody  development  programs  that  are  or  were  in  preclinical  or  early  clinical
studies, including, without limitation, by Merck & Co., Leap Therapeutics, Inc. and Astellas Pharma Inc., and an anti-CAIX antibody in clinical studies by
Telix Pharmaceuticals.

In  the  targeted  anti-cancer  agent  area,  there  are  several  companies  with  marketing  approvals  or  in  development  with  EGFR  inhibitors  that  are  targeting
mutations similar to our programs. There are also a number of early stage programs developing BET inhibitors which could overlap with our upcoming
programs.

In the EGFR inhibitor space, Tarceva®, Iressa®, Gilotrif®, Tagrisso® and Vizimpro® are currently approved drugs for the treatment of first-line EGFR
mutation-positive NSCLC in the United States. AstraZeneca’s Tagrisso is also approved by the FDA for the treatment of patients with metastatic EGFR
T790M mutation-positive NSCLC who have progressed on or after EGFR tyrosine kinase inhibitor therapy and for the adjuvant treatment of patients with
early stage EGFR mutation positive NSCLC. In addition, we are aware of a number of products in development targeting cancer-causing mutant forms of
EGFR for the treatment of NSCLC patients, including, Novartis’ nazartinib, Janssen’s lazertinib, and EQRx’s almonertinib.

In the BET inhibitor space, there are a number of companies which have advanced to early stage clinical trials, including Constellation Pharmaceuticals’
pelabresib,  Bristol-Myers  Squibb’s  BMS-986158,  GlaxoSmithKline’s  molibresib, Abbvie’s  mivebresib,  Incyte’s  INCB57643  and  Zenith  Epigenetics’s
ZEN003694.

Additional information can be found under Item 1A - Risk Factors - Risks Related to Our Business and Industry.

EMPLOYEES

As of December 31, 2021, we had fourteen full and part-time employees. None of our employees are represented by a labor union and we consider our
employee relations to be good.

Table of Contents

SUPPLY AND MANUFACTURING

We have limited experience in manufacturing products for clinical or commercial purposes. We currently do not have any manufacturing capabilities. We
have  established,  or  intend  to  establish,  contract  manufacturing  relationships  for  the  supplies  of  our  product  candidates,  in  each  case  with  a  single
manufacturer. As  with  any  supply  program,  obtaining  raw  materials  of  the  correct  quality  cannot  be  guaranteed  and  we  cannot  ensure  that  we  will  be
successful in this endeavor.

At the time of commercial sale, if not prior, and to the extent possible and commercially practicable, we plan to seek to engage a back-up supplier for each
of our product candidates. Until such time, we expect that we will rely on a single contract manufacturer to produce each of our product candidates under
current GMP (“cGMP”) regulations. Our third-party manufacturers have a limited number of facilities in which our product candidates can be produced and
will  have  limited  experience  in  manufacturing  our  product  candidates  in  quantities  sufficient  for  commercialization.  Our  third-party  manufacturers  will
have  other  clients  and  may  have  other  priorities  that  could  affect  their  ability  to  perform  the  work  satisfactorily  and/or  on  a  timely  basis.  Both  of  these
occurrences would be beyond our control.

We expect to similarly rely on contract manufacturing relationships for any products that we may in-license or acquire in the future. However, there can be
no assurance that we will be able to successfully contract with such manufacturers on terms acceptable to us, or at all.

Contract  manufacturers  are  subject  to  ongoing  periodic  and  unannounced  inspections  by  the  FDA,  the  Drug  Enforcement Administration  (“DEA”)  and
corresponding state agencies to ensure strict compliance with cGMP and other state and federal regulations. Our contractors outside of the United States
face  similar  challenges  from  the  numerous  local  and  regional  agencies  and  authorized  bodies..  We  do  not  have  control  over  third-party  manufacturers’
compliance with these regulations and standards, other than through contractual obligations. If they are deemed out of compliance with cGMPs, product
recalls could result, inventory could be destroyed, production could be stopped, and supplies could be delayed or otherwise disrupted.

If  we  need  to  change  manufacturers  after  commercialization,  the  FDA  and  corresponding  foreign  regulatory  agencies  must  approve  these  new
manufacturers  in  advance,  which  will  involve  testing  and  additional  inspections  to  ensure  compliance  with  FDA  and  corresponding  foreign  regulatory
agency  regulations  and  standards  and  may  require  significant  lead  times  and  delay.  Furthermore,  switching  manufacturers  may  be  difficult  because  the
number of potential manufacturers is limited. It may be difficult or impossible for us to find a replacement manufacturer quickly or on terms acceptable to
us, or at all.

GOVERNMENT AND INDUSTRY REGULATIONS

Numerous governmental authorities, including the FDA and corresponding state and foreign regulatory agencies, impose substantial regulations upon the
clinical  development,  manufacture  and  marketing  of  our  product  candidates,  as  well  as  our  ongoing  research  and  development  activities.  None  of  our
product candidates have been approved for sale in any market in which we have marketing rights. Before marketing in the U.S., any drug that we develop
must undergo rigorous preclinical testing and clinical trials and an extensive regulatory approval process implemented by the FDA under the FDCA. The
FDA regulates, among other things, the pre-clinical and clinical testing, safety, efficacy, approval, manufacturing, record keeping, adverse event reporting,
packaging, labeling, storage, advertising, promotion, export, sale and distribution of biopharmaceutical products.

The  regulatory  review  and  approval  process  is  lengthy,  expensive  and  uncertain.  We  are  required  to  submit  extensive  preclinical  and  clinical  data  and
supporting information to the FDA for each indication or use to establish a product candidate’s safety and efficacy before we can secure FDA approval to
market  or  sell  a  product  in  the  U.S.  The  approval  process  takes  many  years,  requires  the  expenditure  of  substantial  resources  and  may  involve  ongoing
requirements for post-marketing studies or surveillance. Before commencing clinical trials in humans, we must submit an IND to the FDA, or comparable
filing outside the U.S., containing, among other things, pre-clinical data, chemistry, manufacturing and control information, and an investigative plan. Our
submission of an IND may not result in FDA authorization to commence a clinical trial.

12

Table of Contents

The  FDA  may  permit  expedited  development,  evaluation,  and  marketing  of  new  therapies  intended  to  treat  persons  with  serious  or  life-threatening
conditions for which there is an unmet medical need under its fast track drug development programs. A sponsor can apply for fast track designation at the
time of submission of an IND, or at any time prior to receiving marketing approval of the new drug application (“NDA”) or BLA. To receive fast track
designation, an applicant must demonstrate:

●
●
●

that the drug is intended to treat a serious or life-threatening condition;
that the drug is intended to treat a serious aspect of the condition; and
that the drug has the potential to address unmet medical needs, and this potential is being evaluated in the planned drug development program.

The FDA must respond to a request for fast track designation within 60 calendar days of receipt of the request. Over the course of drug development, a
product  in  a  fast  track  development  program  must  continue  to  meet  the  criteria  for  fast  track  designation.  Sponsors  of  products  in  fast  track  drug
development  programs  must  be  in  regular  contact  with  the  reviewing  division  of  the  FDA  to  ensure  that  the  evidence  necessary  to  support  marketing
approval  will  be  developed  and  presented  in  a  format  conducive  to  an  efficient  review.  Sponsors  of  products  in  fast  track  drug  development  programs
ordinarily are eligible for priority review of a completed application in six months or less and also may be permitted to submit portions of an NDA or BLA
to the FDA for review before the complete application is submitted.

Sponsors of drugs designated as fast track also may seek approval under the FDA’s accelerated approval regulations. Under this authority, the FDA may
grant marketing approval for a new drug product 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, based on epidemiologic, therapeutic, pathophysiologic, or other evidence, to predict clinical benefit or on
the basis of an effect on a clinical endpoint other than survival or irreversible morbidity. Approval will be subject to the requirement that the applicant study
the  drug  further  to  verify  and  describe  its  clinical  benefit  where  there  is  uncertainty  as  to  the  relation  of  the  surrogate  endpoint  to  clinical  benefit  or
uncertainty as to the relation of the observed clinical benefit to ultimate outcome. Post-marketing studies are usually underway at the time an applicant files
the NDA or BLA. When required to be conducted, such post-marketing studies must also be adequate and well-controlled. The applicant must carry out any
such post-marketing studies with due diligence. Many companies who have been granted the right to utilize an accelerated approval approach have failed to
obtain approval. Moreover, negative or inconclusive results from the clinical trials we may conduct or adverse medical events could cause us to have to
repeat  or  terminate  the  clinical  trials. Accordingly,  we  may  not  be  able  to  complete  the  clinical  trials  within  an  acceptable  time  frame,  if  at  all,  and,
therefore, could not submit the NDA or BLA to the FDA or foreign regulatory authorities for marketing approval.

Clinical  testing  must  meet  requirements  for  institutional  review  board  or  ethics  committee  oversight,  informed  consent  and  good  clinical  practices,  and
must be conducted pursuant to an IND, unless exempted.

For purposes of NDA or BLA approval, clinical trials are typically conducted in the following sequential phases:

●

●

●
●

Phase 1: The drug is administered to a small group of humans, either healthy volunteers or patients, to test for safety, dosage tolerance, absorption,
metabolism, excretion and clinical pharmacology.
Phase 2: Studies are conducted on a larger number of patients to assess the efficacy of the product, to ascertain dose tolerance and the optimal dose
range, and to gather additional data relating to safety and potential adverse events.
Phase 3: Studies establish safety and efficacy in an expanded patient population.
Phase 4: The FDA may require Phase 4 post-marketing studies to find out more about the drug’s long-term risks, benefits, and optimal use, or to
test the drug in different populations.

The  length  of  time  necessary  to  complete  clinical  trials  varies  significantly  and  may  be  difficult  to  predict.  Clinical  results  are  frequently  susceptible  to
varying interpretations that may delay, limit or prevent regulatory approvals. Additional factors that can cause delay or termination of our clinical trials, or
that may increase the costs of these trials, include:

●

●

slow patient enrollment due to the nature of the clinical trial plan, the proximity of patients to clinical sites, the eligibility criteria for participation in
the study, external factors such as pandemics or geopolitical conflicts or other factors;
inadequately trained or insufficient personnel at the study site to assist in overseeing and monitoring clinical trials or delays in approvals from a
study site’s review board;

13

Table of Contents

●
●
●
●

longer treatment time required to demonstrate efficacy or determine the appropriate product dose;
insufficient supply of the product candidates;
adverse medical events or side effects in treated patients; and
ineffectiveness of the product candidates.

In addition, the FDA, equivalent foreign regulatory authority, or a data safety monitoring committee for a trial may place a clinical trial on hold or terminate
it if it concludes that subjects are being exposed to an unacceptable health risk, or for futility. Any drug is likely to produce some toxicity or undesirable
side effects in animals and in humans when administered at sufficiently high doses and/or for a sufficiently long period of time. Unacceptable toxicity or
side effects may occur at any dose level at any time in the course of studies in animals designed to identify unacceptable effects of a product candidate,
known  as  toxicological  studies,  or  clinical  trials  of  product  candidates.  The  appearance  of  any  unacceptable  toxicity  or  side  effect  could  cause  us  or
regulatory authorities to interrupt, limit, delay or abort the development of any of our product candidates and could ultimately prevent approval by the FDA
or foreign regulatory authorities for any or all targeted indications.

Sponsors of drugs may apply for a special protocol assessment (“SPA”) from the FDA. The SPA process is a procedure by which the FDA provides official
evaluation and written guidance on the design and size of proposed protocols that are intended to form the basis for a new drug application. However, final
marketing approval depends on the results of efficacy, the adverse event profile and an evaluation of the benefit/risk of treatment demonstrated in the Phase
3  trial.  The  SPA  agreement  may  only  be  changed  through  a  written  agreement  between  the  sponsor  and  the  FDA,  or  if  the  FDA  becomes  aware  of  a
substantial scientific issue essential to product safety or efficacy.

Before receiving FDA approval to market a product, we must demonstrate that the product is safe and effective for its intended use by submitting to the
FDA an NDA or BLA containing the pre-clinical and clinical data that have been accumulated, together with chemistry and manufacturing and controls
specifications and information, and proposed labeling, among other things. The FDA may refuse to accept an NDA or BLA for filing if certain content
criteria are not met and, even after accepting an NDA or BLA, the FDA may often require additional information, including clinical data, before approval of
marketing a product.

It is also becoming more common for the FDA to request a Risk Evaluation and Mitigation Strategy (“REMS”), as part of an NDA or BLA. The REMS
plan contains post-market obligations of the sponsor to train prescribing physicians, monitor off-label drug use, and conduct sufficient Phase 4 follow-up
studies and registries to ensure the continued safe use of the drug.

As part of the approval process, the FDA must inspect and approve each manufacturing facility. Among the conditions of approval is the requirement that a
manufacturer’s quality control and manufacturing procedures conform to cGMP. Manufacturers must expend significant time, money and effort to ensure
continued compliance, and the FDA conducts periodic inspections to certify compliance. It may be difficult for our manufacturers or us to comply with the
applicable cGMP, as interpreted by the FDA, and other FDA regulatory requirements. If we, or our contract manufacturers, fail to comply, then the FDA
may not allow us to market products that have been affected by the failure.

If  the  FDA  grants  approval,  the  approval  will  be  limited  to  those  conditions  and  patient  populations  for  which  the  product  is  safe  and  effective,  as
demonstrated through clinical studies. Further, a product may be marketed only in those dosage forms and for those indications approved in the NDA or
BLA.  Certain  changes  to  an  approved  NDA  or  BLA,  including,  with  certain  exceptions,  any  significant  changes  to  labeling,  require  approval  of  a
supplemental  application  before  the  drug  may  be  marketed  as  changed. Any  products  that  we  manufacture  or  distribute  pursuant  to  FDA  approvals  are
subject to continuing monitoring and regulation by the FDA, including compliance with cGMP and the reporting of adverse experiences with the drugs. The
nature of marketing claims that the FDA will permit us to make in the labeling and advertising of our products will generally be limited to those specified in
FDA approved labeling, and the advertising of our products will be subject to comprehensive monitoring and regulation by the FDA. Drugs whose review
was accelerated may carry additional restrictions on marketing activities, including the requirement that all promotional materials are pre-submitted to the
FDA. Claims exceeding those contained in approved labeling will constitute a violation of the FDCA. Violations of the FDCA or regulatory requirements at
any time during the product development process, approval process, or marketing and sale following approval may result in agency enforcement actions,
including withdrawal of approval, recall, seizure of products, warning letters, injunctions, fines and/or civil or criminal penalties. Any agency enforcement
action could have a material adverse effect on our business.

14

Table of Contents

Failure to comply with applicable federal, state and foreign laws and regulations would likely have a material adverse effect on our business. In addition,
federal, state and foreign laws and regulations regarding the manufacture and sale of new drugs are subject to future changes.

Other Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the
Centers  for  Medicare  and  Medicaid  Services  (formerly  the  Health  Care  Financing Administration),  other  divisions  of  the  United  States  Department  of
Health and Human Services (e.g., the Office of Inspector General), the United States Department of Justice and individual United States Attorney offices
within the Department of Justice, and state and local governments.

Pharmaceutical Coverage, Pricing and Reimbursement

In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part
on  the  availability  of  reimbursement  from  third-party  payors,  including  government  health  administrative  authorities,  managed  care  providers,  private
health insurers and other organizations. Third-party payors are increasingly examining the medical necessity and cost-effectiveness of medical products and
services,  in  addition  to  their  safety  and  efficacy,  and,  accordingly,  significant  uncertainty  exists  as  to  the  reimbursement  status  of  newly  approved
therapeutics. Adequate third-party reimbursement may not be available for our products to enable us to realize an appropriate return on our investment in
research and product development. In addition, in the U.S., the Patient Protection and Affordable Care Act (the “Affordable Care Act”) contains provisions
that have the potential to substantially change healthcare delivery and financing, including impacting the profitability of drugs. For example, the Affordable
Care Act revised the methodology by which rebates owed by manufacturers for covered outpatient drugs are calculated under the Medicaid Drug Rebate
Program,  extended  the  Medicaid  Drug  Rebate  Program  to  utilization  of  covered  drugs  dispensed  to  individuals  enrolled  in  Medicaid  managed  care
organizations, and subjected manufacturers to new annual fees for certain branded prescription drugs. Given the complexity of the Affordable Care Act and
the  substantial  requirements  for  regulation  thereunder,  the  impact  of  the  Affordable  Care  Act  on  our  financial  conditions  and  operations  cannot  be
predicted, whether in its current form or as amended or repealed.

International Regulation

In addition to regulations in the United States, there are a variety of foreign regulations governing clinical trials and commercial sales and distribution of
any product candidates. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval.

Item 1A.      Risk Factors

The following information sets forth risk factors that could cause our actual results to differ materially from those contained in forward-looking statements
we have made in this report and those we may make from time to time. You should carefully consider the risks described below, in addition to the other
information  contained  in  this  report  and  our  other  public  filings,  before  making  an  investment  decision.  Our  business,  financial  condition  or  results  of
operations could be harmed by any of these risks. The risks and uncertainties described below are not the only ones we face. Additional risks not presently
known to us or other factors not perceived by us to present significant risks to our business at this time also may impair our business operations.

Risks Related to Our Finances and Capital Requirements

We have incurred significant losses since our inception and anticipate that we will  incur  continued  losses  for  the  foreseeable  future.  We  may  never
achieve or maintain profitability.

We are an emerging growth company with a limited operating history. We have focused primarily on in-licensing and developing our product candidates,
with the goal of supporting regulatory approval for these product candidates. We have incurred losses since our inception in November 2014 and have an
accumulated deficit of $199.9 million as of December 31, 2021. We expect to continue to incur significant operating losses for the foreseeable future. We
also do not anticipate that we will achieve profitability for a period of time after generating material revenues, if ever. If we are unable to generate revenues,
we  will  not  become  profitable  and  may  be  unable  to  continue  operations  without  continued  funding.  Because  of  the  numerous  risks  and  uncertainties
associated with developing pharmaceutical products, we are unable to predict the timing or amount of increased expenses or when or if, we will be able to
achieve  profitability.  Our  net  losses  may  fluctuate  significantly  from  quarter  to  quarter  and  year  to  year.  We  anticipate  that  our  expenses  will  increase
substantially if:

●

one or more of our product candidates are submitted for marketing approval or are approved for commercial sale, due to our need to establish the
necessary commercial infrastructure to launch this product candidate without substantial delays, including manufacturing to build pre-commercial
inventory,  hiring  sales  and  marketing  personnel  and  contracting  with  third  parties  for  warehousing,  distribution,  cash  collection  and  related
commercial activities;

● we are required by the FDA or foreign regulatory authorities, to perform studies in addition to those currently expected;
● we initiate one or more clinical trials to pursue additional indications for our product candidates, or if there are any delays in completing our clinical

trials or the development of any of our product candidates;

● we execute other collaborative, licensing or similar arrangements and the timing of payments we may make or receive under these arrangements;
●
●
●
●

there are variations in the level of expenses related to our current and future development programs;
there are any product liability or intellectual property infringement lawsuits in which we may become involved;
there are any regulatory developments affecting product candidates of our competitors; and
one or more of our product candidates receives regulatory approval.

Our  ability  to  become  profitable  depends  upon  our  ability  to  generate  revenue.  To  date,  we  have  not  generated  any  revenue  from  the  sale  of  our
development stage products, and we do not know when, or if, we will generate any revenue. To obtain revenues from sales of our product candidates, we
must succeed, either alone or with third parties, in developing, obtaining regulatory approval for, manufacturing and marketing products with commercial
potential. Our ability to generate revenue depends on a number of factors, including, but not limited to, our ability to:

obtain regulatory approval for one or more of our product candidates, or any future product candidate that we may license or acquire;

●
● manufacture commercial quantities of one or more of our product candidates or any future product candidate, if approved, at acceptable cost levels;

●

and
develop a commercial organization and the supporting infrastructure required to successfully market and sell one or more of our product candidates
or any future product candidate, if approved.

Even 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  depress  the  value  of  our  company  and  could  impair  our  ability  to  raise  capital,  expand  our  business,  maintain  our  research  and
development efforts, diversify our product offerings or even continue our operations. A decline in the value of our company could also cause you to lose all
or part of your investment.

Our short operating history makes it difficult to evaluate our business and prospects.

We  were  incorporated  in  November  2014  and  have  only  been  conducting  operations  with  respect  to  our  product  candidates  since  March  2015.  Our
operations to date have been limited to preclinical and clinical operations and the in-licensing of our product candidates. We have not yet demonstrated an
ability to successfully complete clinical trials, obtain regulatory approvals, manufacture a commercial scale product, or arrange for a third party to do so on
our behalf, or conduct sales and marketing activities necessary for successful

16

product commercialization. Consequently, any predictions about our future performance may not be as accurate as they could be if we had a history of
successfully developing and commercializing pharmaceutical products.

In addition, as a young business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We will
need  to  expand  our  capabilities  to  support  increased  clinical  and  manufacturing  activities  and  future  potential  commercial  activities.  We  may  not  be
successful in adding such capabilities.

We expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety of
factors, many of which are beyond our control. Accordingly, you should not rely upon the results of any past quarterly period as an indication of future
operating performance.

We  will  require  substantial  additional  funding  which  may  not  be  available  to  us  on  acceptable  terms,  or  at  all.  If  we  fail  to  raise  the  necessary
additional  capital,  we  may  be  unable  to  complete  the  development  and  commercialization  of  our  product  candidates,  or  continue  our  development
programs.

Our operations have consumed substantial amounts of cash since inception. We expect to significantly increase our spending to advance the preclinical and
clinical  development  of  our  product  candidates  and  launch  and  commercialize  any  product  candidates  for  which  we  may  receive  regulatory  approval,
including  building  our  own  commercial  organizations  to  address  certain  markets.  We  will  require  additional  capital  for  the  further  development  and,  if
approved, commercialization of our product candidates, as well as to fund our other operating expenses and capital expenditures. We currently believe that
our cash and cash equivalents balances are sufficient to fund our anticipated operating cash requirements for at least one year from the date of issuance of
this Annual Report on Form 10-K.

We cannot be certain that additional funding will be available on acceptable terms, or at all. If we are unable to raise additional capital in sufficient amounts
or on terms acceptable to us we may have to significantly delay, scale back or discontinue the development or, if approved, commercialization of one or
more  of  our  product  candidates.  We  may  also  seek  collaborators  for  one  or  more  of  our  current  or  future  product  candidates  at  an  earlier  stage  than
otherwise  would  be  desirable  or  on  terms  that  are  less  favorable  than  might  otherwise  be  available. Any  of  these  events  could  significantly  harm  our
business, financial condition and prospects.

Our future funding requirements will depend on many factors, including, but not limited to:

●
●
●
●

●

●

●
●
●

●

the timing, design and conduct of, and results from, preclinical studies and clinical trials for our product candidates;
the potential for delays in our efforts to seek regulatory approval for our product candidates, and any costs associated with such delays;
the costs of establishing a commercial organization to sell, market and distribute our product candidates;
the  rate  of  progress  and  costs  of  our  efforts  to  prepare  for  the  submission  of  an  NDA  or  BLA  for  any  of  our  product  candidates  or  any  product
candidates  that  we  may  in-license  or  acquire  in  the  future,  and  the  potential  that  we  may  need  to  conduct  additional  clinical  trials  to  support
applications for regulatory approval;
the  costs  of  filing,  prosecuting,  defending  and  enforcing  any  patent  claims  and  other  intellectual  property  rights  associated  with  our  product
candidates, including any such costs we may be required to expend if our licensors are unwilling or unable to do so;
the cost and timing of securing sufficient supplies of our product candidates from our third-party manufacturers for clinical trials and in preparation
for commercialization;
the effect of competing technological and market developments;
the terms and timing of any collaborative, licensing, co-promotion or other arrangements that we may establish;
if  one  or  more  of  our  product  candidates  are  approved,  the  potential  that  we  may  be  required  to  file  a  lawsuit  to  defend  our  patent  rights  or
regulatory exclusivities from challenges by companies seeking to market generic versions of one or more of our product candidates; and
the success of the commercialization of one or more of our product candidates, if approved.

Future capital requirements will also depend on the extent to which we acquire or invest in additional complementary businesses, products and technologies,
but we currently have no commitments or agreements relating to any of these types of transactions.

17

In order to carry out our business plan and implement our strategy, we anticipate that we will need to obtain additional financing from time to time and may
choose to raise additional funds through strategic collaborations, licensing arrangements, public or private equity or debt financing, bank lines of credit,
asset sales, government grants, or other arrangements. We cannot be sure that any additional funding, if needed, will be available on terms favorable to us or
at all. Furthermore, any additional equity or equity-related financing may be dilutive to our stockholders, and debt or equity financing, if available, may
subject us to restrictive covenants and significant interest costs. If we obtain funding through a strategic collaboration or licensing arrangement, we may be
required to relinquish our rights to certain of our product candidates or marketing territories.

Our inability to raise capital when needed would harm our business, financial condition and results of operations, and could cause our stock price to decline
or require that we wind down our operations altogether.

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

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings,
debt financings, grants and license and development agreements in connection with any collaborations. To the extent that we raise additional capital through
the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other
preferences  that  adversely  affect  your  rights  as  a  stockholder.  Debt  financing  and  preferred  equity  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 additional funds through collaborations, strategic alliances or marketing, distribution 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 grant licenses on terms that may not be
favorable to us. If we are unable to raise additional funds through equity or debt financings 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.

We are an “emerging growth company” and a “smaller reporting company,” and the reduced disclosure requirements applicable to emerging growth
companies and smaller reporting companies may make our common stock less attractive to investors.

We  are  an  “emerging  growth  company”  as  that  term  is  used  in  the  Jumpstart  Our  Business  Startups Act  of  2012  (“JOBS Act”),  and  may  remain  an
emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of the initial public
offering  of  our  common  stock,  (b)  in  which  we  have  total  annual  gross  revenue  of  at  least  $1.07  billion,  or  (c)  in  which  we  are  deemed  to  be  a  large
accelerated filer, which means the market value of our outstanding common stock that are held by non-affiliates exceeds $700 million as of the prior June
30, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three year period. For so long as we remain an
emerging  growth  company,  we  are  permitted  and  intend  to  rely  on  exemptions  from  certain  disclosure  requirements  that  are  applicable  to  other  public
companies that are not emerging growth companies. These exemptions include:

●

●
●

●
●

being permitted to provide only two years of our audited financial statements, in addition to any required unaudited interim financial statements,
with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure in this Annual
Report on Form 10-K;
not being required to comply with the auditor attestation requirements in the assessment of our internal control over financial reporting;
not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory
audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;
disclosure obligations regarding executive compensation; and
exemptions  from  the  requirements  of  holding  a  nonbinding  advisory  vote  on  executive  compensation  and  shareholder  approval  of  any  golden
parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting
standards  until  private  companies  (that  is,  those  that  have  not  had  a  Securities Act  registration  statement  declared  effective  or  do  not  have  a  class  of
securities registered under the Exchange Act) are required to comply with the new or revised financial

18

Table of Contents

accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that
apply to non-emerging growth companies but any such an election to opt out is irrevocable. We have elected to opt out of such extended transition period
which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth
company, will adopt the new or revised standard. This may make comparison of our financial statements with another public company which has opted into
using the extended transition period difficult or impossible because of the potential differences in accountant standards used.

We are also a smaller reporting company, and we will remain a smaller reporting company until the fiscal year following the determination that our voting
and  non-voting  common  shares  held  by  non-affiliates  is  more  than  $250  million  measured  on  the  last  business  day  of  our  second  fiscal  quarter,  or  our
annual revenues are more than $100 million during the most recently completed fiscal year and our voting and non-voting common shares held by non-
affiliates is more than $700 million measured on the last business day of our second fiscal quarter. Similar to emerging growth companies, smaller reporting
companies are able to provide simplified executive compensation disclosure, are exempt from the auditor attestation requirements of Section 404, and have
certain other reduced disclosure obligations, including, among other things, being required to provide only two years of audited financial statements and not
being required to provide selected financial data, supplemental financial information or risk factors.

We have elected to take advantage of certain of the reduced reporting obligations. We cannot predict whether investors will find our common stock less
attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for
our common stock and our stock price may be reduced or more volatile.

We may expend our limited resources to pursue certain product candidates or indications and fail to capitalize on product candidates or indications 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  research  programs  and  product  candidates  that  we  identify  for  specific
indications. As  a  result,  we  may  forego  or  delay  pursuit  of  opportunities  with  other  product  candidates  or  for  other  indications  that  later  prove  to  have
greater  commercial  potential.  Our  resource  allocation  decisions  may  cause  us  to  fail  to  capitalize  on  viable  commercial  products  or  profitable  market
opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any
commercially  viable  products.  If  we  do  not  accurately  and/or  effectively  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.

Risks Related to our Business Strategy, Structure, and Organization

We currently have no drug products for sale and are dependent on the future success of our product candidates. We can give no assurances that any of
our product candidates will receive regulatory approval or be successfully commercialized.

To date, we have invested a significant portion of our efforts and financial resources in the acquisition and development of our product candidates. As a
development-stage  company,  we  have  limited  experience  and  have  not  yet  demonstrated  an  ability  to  successfully  overcome  many  of  the  risks  and
uncertainties  frequently  encountered  by  companies  in  new  and  rapidly  evolving  fields,  particularly  in  the  biopharmaceutical  area.  Our  future  success  is
substantially  dependent  on  our  ability  to  successfully  develop,  obtain  regulatory  approval  for,  and  then  successfully  commercialize  such  product
candidates.  Our  product  candidates  are  currently  in  preclinical  development  or  in  clinical  trials.  Our  business  depends  entirely  on  the  successful
development and commercialization of our product candidates, which may never occur. We currently have no drug products for sale, currently generate no
revenues from sales of any drug products and may never be able to develop or commercialize a marketable drug.

The successful development, and any commercialization of our technologies and any product candidates that may occur, would require us to successfully
perform a variety of functions, including:

●
●
●
●

developing our technology platform;
identifying, developing, formulating, manufacturing and commercializing product candidates;
entering into and maintaining successful licensing and other arrangements with product development partners;
achieving clinical endpoints to support preparation of approval applications;

19

Table of Contents

●
●

●
●

participating in regulatory approval processes, including ultimately gaining approval to market a drug product, which may not occur; 
obtaining sufficient quantities of our product candidates from our third-party manufacturers to meet clinical trial needs and, if approved, to meet
commercial demand at launch and thereafter;
establishing and maintaining agreements with wholesalers, distributors and group purchasing organizations on commercially reasonable terms;
conducting  sales  and  marketing  activities  including  hiring,  training,  deploying  and  supporting  a  sales  force  and  creating  market  demand  for  our
product  candidates  through  our  own  marketing  and  sales  activities,  and  any  other  arrangements  to  promote  our  product  candidates  that  we  may
establish;

● maintaining patent protection and regulatory exclusivity for our product candidates; and
●

obtaining market acceptance for our product candidates.

Each of these requirements will require substantial time, effort and financial resources.

We intend to use data from our ongoing Phase 1 clinical trial of cosibelimab, conducted outside the United States, in checkpoint therapy-naïve patients
with selected recurrent or metastatic cancers, including CSCC, to potentially support one or more U.S. BLAs and comparable applications for marketing
approval outside the U.S. In January 2020, we announced that we had discussed with the FDA this strategy in CSCC. Similarly, we intend to use data from
our licensor’s ongoing Phase 3 clinical trial of olafertinib (formerly CK-101), conducted only in China, in patients with EGFR mutation-positive NSCLC, to
potentially  support  a  U.S.  NDA  and  comparable  applications  for  marketing  approval  outside  the  U.S.  We  believe,  based  on  published  FDA  guidance
documents, public statements of companies with comparable product candidates, and recent interactions with the FDA, that exclusively foreign clinical data
from a single study may be acceptable to support marketing approval(s) under FDA regulations. If we prove to be incorrect, running additional studies in
the U.S. will require substantial time, effort and financial resources or may not be possible at all.

Our operations have been limited  to  organizing  our  company,  acquiring,  developing  and  securing  our  proprietary  technologies  and  obtaining  preclinical
data or clinical data for various product candidates. These operations provide a limited basis for you to assess our ability to continue to identify product
candidates,  develop  and  commercialize  product  candidates  in  our  portfolio  and  any  product  candidates  we  are  able  to  identify  and  enter  into  successful
collaborative arrangements with other companies in the future, as well as for you to assess the advisability of investing in our securities.

Each of our product candidates will require additional preclinical or clinical development, management of preclinical, clinical and manufacturing activities,
regulatory approval in the jurisdictions in which we plan to market the product, obtaining manufacturing supply, building of a commercial organization, and
significant marketing efforts before we generate any revenues from product sales, which may not occur. We are not permitted to market or promote any of
our product candidates in the U.S. or any other jurisdiction before we receive regulatory approval from the FDA or comparable foreign regulatory authority,
respectively, and we may never receive such regulatory approval for any of our product candidates.

Our  future  growth  depends  on  our  ability  to  identify  and  acquire  or  in-license  products  and  successfully  integrating  such  acquired  or  in-licensed
products into our existing operations.

An important part of our business strategy is to continue to develop a pipeline of product candidates by acquiring or in-licensing products, businesses or
technologies  that  we  believe  are  a  strategic  fit  with  our  focus  on  novel  combinations  of  immuno-oncology  antibodies  and  small  molecule  targeted  anti-
cancer agents. Future in-licenses or acquisitions, however, may entail numerous operational and financial risks, including:

●
●
●

●
●
●
●

exposure to unknown liabilities;
disruption of our business and diversion of our management’s time and attention to develop acquired products or technologies;
difficulty  or  inability  to  secure  financing  to  fund  development  activities  for  such  acquired  or  in-licensed  technologies  in  the  current  economic
environment;
incurrence of substantial debt or dilutive issuances of securities to pay for acquisitions;
higher than expected acquisition and integration costs;
increased amortization expenses;
difficulty and cost in combining the operations and personnel of any acquired businesses with our operations and personnel;

20

Table of Contents

●
●

impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and
inability to retain key employees of any acquired businesses.

We have limited resources to identify and execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them
into our current infrastructure. In particular, we may compete with larger pharmaceutical companies and other competitors in our efforts to establish new
collaborations  and  in-licensing  opportunities.  These  competitors  likely  will  have  access  to  greater  financial  resources  than  us  and  may  have  greater
expertise in identifying and evaluating new opportunities. Moreover, we may devote resources to potential acquisitions or in-licensing opportunities that are
never completed, or we may fail to realize the anticipated benefits of such efforts.

Risks Inherent in Drug Development and Commercialization

Because results of preclinical studies and early clinical trials are not necessarily predictive of future results, any product candidate we advance may not
have favorable results in later clinical trials or receive regulatory approval.  Moreover, interim, “top-line,” and preliminary data from our clinical trials
that we announce or publish may change, or the perceived product profile may be negatively impacted, as more patient data or additional endpoints
(including efficacy and safety) are analyzed.

Pharmaceutical  development  has  inherent  risks.  The  outcome  of  preclinical  development  testing  and  early  clinical  trials  may  not  be  predictive  of  the
outcome of later 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  product  candidates.  Once  a  product  candidate  has  displayed
sufficient preclinical data to warrant clinical investigation, we will be required to demonstrate through adequate and well-controlled clinical trials that our
product  candidates  are  effective  with  a  favorable  benefit-risk  profile  for  use  in  populations  for  their  target  indications  before  we  can  seek  regulatory
approvals for their commercial sale. Many drug candidates fail in the early stages of clinical development for safety and tolerability issues or for insufficient
clinical  activity,  despite  promising  preclinical  results. Accordingly,  no  assurance  can  be  made  that  a  safe  and  efficacious  dose  can  be  found  for  these
compounds  or  that  they  will  ever  enter  into  advanced  clinical  trials  alone  or  in  combination  with  other  product  candidates.    Moreover,  success  in  early
clinical  trials  does  not  mean  that  later  clinical  trials  will  be  successful  because  product  candidates  in  later-stage  clinical  trials  may  fail  to  demonstrate
sufficient  safety  or  efficacy  despite  having  progressed  through  initial  clinical  testing.  Companies  frequently  experience  significant  setbacks  in  advanced
clinical  trials,  even  after  earlier  clinical  trials  have  shown  promising  results.  There  is  an  extremely  high  rate  of  failure  of  pharmaceutical  candidates
proceeding through clinical trials.

Individually reported outcomes of patients treated in clinical trials may not be representative of the entire population of treated patients in such studies. In
addition,  registration  or  larger  scale  Phase  3  studies,  which  are  often  conducted  internationally,  are  inherently  subject  to  increased  operational  risks
compared to earlier stage studies, including the risk that the results could vary on a region to region or country to country basis, which could materially
adversely affect the outcome of the study or the opinion of the validity of the study results by applicable regulatory agencies.

From time to time, we may publicly disclose top-line or preliminary data from our clinical trials, which is based on a preliminary analysis of then available
data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular
study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of such data, and we may not have received or
had the opportunity to fully and carefully evaluate all data from the particular study or trial, including all endpoints and safety data. As a result, top-line 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. Top-line or preliminary data also remain subject to audit and verification procedures that may
result in the final data being materially different from the topline, interim, or preliminary data we previously published. When providing top-line results, we
may disclose the primary endpoint of a study before all secondary endpoints have been fully analyzed.  A positive primary endpoint does not translate to all,
or any, secondary endpoints being met. As a result, top-line and preliminary data should be viewed with caution until the final data are available, including
data from the full safety analysis and the final analysis of all endpoints.

Further, 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. For example, many of the results reported in our early clinical trials rely on local

21

Table of Contents

investigator-assessed efficacy outcomes which may be subject to greater variability or subjectivity than results assessed in a blinded, independent, centrally
reviewed manner, often required of final or later phase, adequate and well-controlled registration-directed clinical trials. If the results from our registration-
directed trials are different from the results found in the earlier studies, we may need to terminate or revise our clinical development plan, which could
extend the time for conducting our development program and could have a material adverse effect on our business. Also, time-to-event based endpoints
such  as  duration  of  response  and  progression-free  survival  have  the  potential  to  change,  sometimes  drastically,  with  longer  follow-up.  In  addition,  as
patients continue on therapy, there can be no assurance given that the final safety data from studies, once fully analyzed, will be consistent with prior safety
data  presented,  will  be  differentiated  from  other  similar  agents  in  the  same  class,  will  support  continued  development,  or  will  be  favorable  enough  to
support  regulatory  approvals  for  the  indications  studied.    Further,  others,  including  regulatory  agencies,  may  not  accept  or  agree  with  our  assumptions,
estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular
program, the approvability or commercialization of the particular product candidate or product and our company in general. The information we choose to
publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and regulators or others may not agree
with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line or preliminary data that we
report differ from final results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, or
successfully commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Delays in clinical testing could result in increased costs to us and delay our ability to generate revenue.

Although we are planning for certain clinical trials relating to our product candidates, there can be no assurance that the FDA, or any comparable foreign
regulatory authority, will accept our proposed trial designs. We may experience delays in our clinical trials and we do not know whether current or planned
clinical trials will begin on time, need to be redesigned, enroll patients on time or be completed on schedule, if at all. Clinical trials can be delayed for a
variety of reasons, including delays related to:

●
●

●
●
●
●
●
●
●
●

obtaining regulatory approval to commence a trial;
reaching agreement on acceptable terms with prospective contract research organizations (“CROs”), and clinical trial sites, the terms of which can
be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
obtaining institutional review board (“IRB”), or ethics committee, as applicable, approval at each site;
recruiting a sufficient number of suitable patients to participate in a trial;
clinical sites deviating from trial protocol or dropping out of a trial;
having patients complete a trial or return for post-treatment follow-up;
developing and validating companion diagnostics on a timely basis, if required;
obtaining resolution for any clinical holds that arise from the FDA or any comparable foreign regulatory authority;
adding new clinical trial sites; or
availability of raw materials or manufacturing sufficient quantities of product candidate for use in clinical trials.

We could encounter delays if a clinical trial is suspended or terminated by us, by the IRBs or ethics committees of the institutions in which such trials are
being conducted, by the Data Safety Monitoring Board for such trial or by the FDA or other regulatory authorities. Such authorities may impose such a
suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical
protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold,
unforeseen  safety  issues  or  adverse  side  effects,  failure  to  demonstrate  a  benefit  from  using  a  drug  candidate,  changes  in  governmental  regulations  or
administrative actions or lack of adequate funding to continue the clinical trial.

If  we  experience  delays  in  the  completion  of,  or  termination  of,  any  clinical  trial  of  our  product  candidates,  the  commercial  prospects  of  our  product
candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed, or such revenues may not be
generated at all. In addition, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval
process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition
and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also
ultimately lead to the denial of regulatory approval of our product candidates.

22

Table of Contents

Difficulties in the enrollment of patients in clinical trials may prevent or delay receipt of necessary regulatory approvals.

Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the
proximity of patients to clinical sites, the eligibility criteria for the trial, the design of the clinical trial, competing clinical trials and clinicians’ and patients’
perceptions as to the potential advantages of the drug being studied in relation to other available therapies, including any new drugs that may be approved
for  the  indications  we  are  investigating.  Furthermore,  we  intend  to  rely  on  CROs  and  clinical  trial  sites  to  ensure  the  proper  and  timely  conduct  of  our
clinical trials and we intend to have agreements governing their committed activities, however, we will have limited influence over their actual performance.

We may not be able to initiate or continue clinical trials for one or more of our product candidates 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. Some of our competitors
have ongoing clinical trials for product candidates that treat the same indications that we are targeting for our product candidates, and patients who would
otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates. Available therapies for the indications
we are pursuing can also affect enrollment in our clinical trials. Patient enrollment is affected by other factors including:

●
●
●
●
●
●
●
●

the severity of the disease under investigation;
the eligibility criteria for the study in question;
the perceived risks and benefits of the product candidate under study;
the efforts to facilitate timely enrollment in clinical trials;
the patient referral practices of physicians;
the number of clinical trials sponsored by other companies for the same patient population;
the ability to monitor patients adequately during and after treatment; and
the proximity and availability of clinical trial sites for prospective patients.

Our inability to enroll a sufficient number of patients for our clinical trials would result in significant delays and could require us to abandon one or more
clinical  trials  altogether.  Enrollment  delays  in  our  clinical  trials  may  result  in  increased  development  costs  for  our  product  candidates  or  future  product
candidates, which would cause the value of our company to decline and limit our ability to obtain additional financing.

Russian military action in Europe may impact foreign countries in which we may need to enroll patients in our clinical trials and could cause such
clinical trials to be delayed or suspended.

In  February  2022,  Russia  commenced  a  military  invasion  of  Ukraine.  Russia's  invasion  and  the  ensuing  response  by  Ukraine  may  disrupt  our  ability  to
conduct clinical trials in Russia, Ukraine, Belarus, and Georgia. Although the route, length and impact of Russia's military action is highly unpredictable,
our  clinical  trial  sites  in  Russia,  Ukraine,  Belarus,  and  Georgia  may  suspend  or  terminate  trials,  and  patients  could  be  forced  to  evacuate  or  choose  to
relocate, making them unavailable for initial or further participation in our clinical trials. Alternative sites to fully and timely compensate for our clinical
trial activities in these areas may not be available and we may need to find other countries to conduct these clinical trials. Furthermore, Russian military
action  may  prevent  the  FDA  from  auditing  our  clinical  sites  in  these  countries  upon  review  of  our  planned  BLA  for  cosibelimab.  Interruptions  of  our
clinical trials, particularly of the CONTERNO study, may delay our clinical development and approvals for our product candidates, which could increase
our costs and jeopardize our ability to commence product sales and generate revenues.

We may not receive regulatory approval for our product candidates, or their approval may be delayed, which would have a material adverse effect on
our business and financial condition.

Our  product  candidates  and  the  activities  associated  with  their  development  and  commercialization,  including  their  design,  testing,  manufacture,  safety,
efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA, by
other  regulatory  agencies  in  the  United  States,  by  the  European  Medicines Agency  and  by  comparable  foreign  regulatory  authorities  outside  the  United
States.  Failure  to  obtain  marketing  approval  for  one  or  more  of  our  product  candidates  or  any  future  product  candidate  will  prevent  us  from
commercializing  the  product  candidate.  We  have  not  received  approval  to  market  any  of  our  product  candidates  from  regulatory  authorities  in  any
jurisdiction. We have only limited experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on third-
party CROs and other third-party vendors

23

Table of Contents

to assist us in this process. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information to
regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing marketing approval also requires the
submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, regulatory authorities. One or more of
our  product  candidates  or  any  future  product  candidate  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 preclude our obtaining marketing approval or prevent or limit commercial use. If any of
our product candidates or any future product candidate receives marketing approval, the accompanying label may limit the approved use of our drug by
severity of disease, patient group, or include contraindications, interactions, or warnings, which could limit sales of the product.

The process of obtaining marketing approval, both in the United States and abroad, is expensive, may take many 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. Changes in marketing
approval policies during the development period, changes in available therapies and standards of care, changes in or the enactment of additional statutes or
regulations,  or  changes  in  regulatory  review  for  each  submitted  product  application,  may  cause  delays  in  the  approval  or  rejection  of  an  application.
Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our study design,
including  the  control  arm  used  in  our  study,  or  data  are  insufficient  for  approval  and  require  additional  preclinical  studies  or  clinical  trials.  In  addition,
varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent marketing approval of a product candidate.
Any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not
commercially viable.

Under  the  FDA’s  accelerated  approval  regulations,  which  only  apply  to  certain  drug  products,  the  FDA  may  grant  marketing  approval  for  a  new  drug
product 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, based on epidemiologic, therapeutic, pathophysiologic, or other evidence, to predict clinical benefit or on the basis of an effect on a clinical endpoint
other than survival or irreversible morbidity. While we may undertake development programs for one or more of our product candidates that we believe, if
successful, could support a submission for marketing approval under the accelerated approval regulations, we may ultimately fail to meet the criteria to do
so, which may cause delays in the approval or rejection of an application.

If we experience delays in obtaining approval or if we fail to obtain approval of one or more of our product candidates or any future product candidate, the
commercial prospects for our product candidates may be harmed and our ability to generate revenue will be materially impaired.

In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates or any future product candidate for fewer
or  more  limited  indications  than  we  request,  may  not  approve  the  price  we  intend  to  charge  for  our  products,  may  grant  approval  contingent  on  the
performance of costly post-marketing studies, including clinical trials, or may approve a product candidate with a label that does not include the labeling
claims necessary or desirable for the successful commercialization of that product candidate. The regulatory authority may also require the label to contain
warnings,  contraindications,  or  precautions  that  limit  the  commercialization  of  that  product. Any  of  these  scenarios  could  compromise  the  commercial
prospects for one or more of our product candidates or any future product candidate.

If serious adverse or unacceptable side effects are identified during the development of one or more of our product candidates or any future product
candidate, we may need to abandon or limit our development of some of our product candidates.

If one or more of our product candidates or any future product candidate are associated with undesirable side effects or adverse events in clinical trials or
have characteristics that are unexpected, we may need to abandon their development or limit development to more narrow uses or subpopulations in which
the adverse events, undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. In our
industry, many compounds that initially showed promise in early-stage testing have later been found to cause serious adverse events that prevented further
development of the compound. In the event that our clinical trials reveal a high or unacceptable severity and prevalence of adverse events, our trials could
be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development or deny approval of one
or more of our product candidates or any future product candidate for any or all targeted indications. The FDA could also issue a letter requesting additional
data  or  information  prior  to  making  a  final  decision  regarding  whether  to  approve  a  product  candidate.  The  number  of  requests  for  additional  data  or
information  issued  by  the  FDA  in  recent  years  has  increased  and  resulted  in  substantial  delays  in  the  approval  of  several  new  drugs. Adverse  events  or
undesirable side effects caused by one or more of our product candidates or any future product

24

Table of Contents

candidate could also result in the inclusion of unfavorable information in our product labeling, denial of regulatory approval by the FDA or other regulatory
authorities for any or all targeted indications, and in turn prevent us from commercializing and generating revenues from the sale of that product candidate.
Adverse  events  or  drug-related  side  effects  could  affect  patient  recruitment  or  the  ability  of  enrolled  patients  to  complete  the  trial  and  could  result  in
potential product liability claims.

Additionally,  if  one  or  more  of  our  product  candidates  or  any  future  product  candidate  receives  marketing  approval  and  we  or  others  later  identify
undesirable side effects caused by this product, a number of potentially significant negative consequences could result, including:

●

regulatory  authorities  may  require  the  addition  of  unfavorable  labeling  statements,  including  specific  warnings,  black  box  warnings,  adverse
reactions, precautions, and/or contraindications;
regulatory authorities may suspend or withdraw their approval of the product, and/or require it to be removed from the market;

●
● we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product; or
●

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of any of our product candidates or any future product candidate or
could substantially increase our commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues, or any
revenues, from its sale.

Public  concern  regarding  the  safety  of  drug  products  could  delay  or  limit  our  ability  to  obtain  regulatory  approval,  result  in  the  inclusion  of
unfavorable information in our labeling, or require us to undertake other activities that may entail additional costs.

In light of widely publicized events concerning the safety risk of certain drug products, the FDA, members of Congress, the Government Accountability
Office, medical professionals and the general public have raised concerns about potential drug safety issues. These events have resulted in the withdrawal of
drug  products,  revisions  to  drug  labeling  that  further  limit  use  of  the  drug  products  and  the  establishment  of  risk  management  programs.  The  Food  and
Drug Administration Amendments Act of 2007 (“FDAAA”), grants significant expanded authority to the FDA, much of which is aimed at improving the
safety of drug products before and after approval. In particular, the new law authorizes the FDA to, among other things, require post-approval studies and
clinical trials, mandate changes to drug labeling to reflect new safety information and require risk evaluation and mitigation strategies for certain drugs,
including  certain  currently  approved  drugs.  It  also  significantly  expands  the  federal  government’s  clinical  trial  registry  and  results  databank,  which  we
expect will result in significantly increased government oversight of clinical trials. Under the FDAAA, companies that violate these and other provisions of
the new law are subject to substantial civil monetary penalties, among other regulatory, civil and criminal penalties. The increased attention to drug safety
issues  may  result  in  a  more  cautious  approach  by  the  FDA  in  its  review  of  data  from  our  clinical  trials.  Data  from  clinical  trials  may  receive  greater
scrutiny, particularly with respect to safety, which may make the FDA or other regulatory authorities more likely to require additional preclinical studies or
clinical trials. If the FDA requires us to conduct additional preclinical studies or clinical trials prior to approving any of our product candidates, our ability to
obtain approval of this product candidate will be delayed. If the FDA requires us to provide additional clinical or preclinical data following the approval of
any of our product candidates, the indications for which this product candidate is approved may be limited or there may be specific warnings or limitations
on dosing, and our efforts to commercialize our product candidates may be otherwise adversely impacted.

Even if one or more of our product candidates receives regulatory approval, it and any other products we may market will remain subject to substantial
regulatory scrutiny.

If  one  or  more  of  our  product  candidates  that  we  may  license  or  acquire  is  approved,  the  approved  product  candidate  will  be  subject  to  ongoing
requirements  and  review  by  the  FDA  and  other  regulatory  authorities.  These  requirements  include  labeling,  packaging,  storage,  advertising,  promotion,
record-keeping and submission of safety and other post-market information and reports, registration and listing requirements, cGMP requirements relating
to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of
samples to physicians and recordkeeping of the drug, and requirements regarding company presentations and interactions with health care professionals.

The FDA, or other regulatory authorities, may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the
safety or efficacy of the product. The FDA and other applicable regulatory authorities closely regulate the post-approval marketing and promotion of drugs
to ensure drugs are marketed only for the approved indications and in accordance with

25

Table of Contents

the  provisions  of  the  approved  labeling.  The  FDA  and  other  applicable  regulatory  authorities  impose  stringent  restrictions  on  manufacturers’
communications regarding off-label use and if we do not market our products for only their approved indications, we may be subject to enforcement action
for off-label marketing. Violations of the Federal Food, Drug and Cosmetic Act relating to the promotion of prescription drugs may lead to investigations,
civil claims, and/or criminal charges alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.

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

restrictions on such products, operations, 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 letters, untitled letters, import alerts, and/or inspection observations;
● 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;
suspension or withdrawal of marketing or regulatory approvals;
suspension of any ongoing clinical trials;
refusal to permit the import or export of our products;
product seizure; or
injunctions, consent decrees, and/or the imposition of civil or criminal penalties.

The FDA’s policies, or the policies of other applicable regulatory authorities, may change and additional government regulations may be enacted that could
prevent,  limit  or  delay  regulatory  approval  of  our  product  candidates,  or  negatively  affect  those  products  for  which  we  may  have  already  received
regulatory approval, if any. 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 be subject to the various actions listed above, including losing any marketing approval that we may
have obtained.

Regulatory approval by the FDA, or any similar regulatory authorities outside the United States, is limited to those specific indications and conditions
for which clinical safety and efficacy have been demonstrated.

Any regulatory approval is limited to those specific diseases and indications for which a product is deemed to be safe and effective by the FDA, or other
similar  regulatory  authorities  outside  the  United  States.  In  addition  to  the  regulatory  approval  required  for  new  drug  products,  new  formulations  or
indications for an approved product also require regulatory approval. If we are not able to obtain regulatory approval for any desired future indications for
our products, our ability to effectively market and sell our products may be prevented or reduced, and our business may be adversely affected.

While physicians may choose to prescribe drugs for uses that are not described in the product’s labeling and for uses that differ from those tested in clinical
studies and approved by the regulatory authorities, our ability to promote products is limited to those indications that are specifically approved by the FDA,
or similar regulatory authorities outside the United States. These “off-label” uses are common across medical specialties and may constitute an appropriate
treatment for some patients in certain circumstances. Regulatory authorities in the U.S. generally do not regulate the behavior of physicians in their choice
of  treatments.  Regulatory  authorities  do,  however,  restrict  promotion  by  pharmaceutical  companies  on  the  subject  of  off-label  use.  If  our  promotional
activities fail to comply with these regulations or guidelines, we may be subject to warnings from, or enforcement action by, these authorities. In addition,
our failure to follow FDA, or any applicable foreign regulatory authority, rules and guidelines relating to promotion and advertising may cause the FDA, or
such applicable foreign regulatory authority, to suspend or withdraw an approved product from the market, require a recall or institute fines or penalties, or
could result in disgorgement of money, operating restrictions, injunctions or criminal prosecution, any of which could harm our business.

We  will  need  to  obtain  FDA  approval  of  any  proposed  product  brand  names,  and  any  failure  or  delay  associated  with  such  approval  may  adversely
impact our business.

A pharmaceutical product cannot be marketed in the U.S. or other countries until we have completed a rigorous and extensive regulatory review process,
including  approval  of  a  brand  name. Any  brand  names  we  intend  to  use  for  our  product  candidates  will  require  approval  from  the  FDA  regardless  of
whether we have secured a formal trademark registration from the United States Patent and Trademark Office (“USPTO”). The FDA typically conducts a
review of proposed product brand names, including an evaluation of the potential for confusion with other product names. The FDA may also object to a
product brand name if it believes the name inappropriately implies medical claims. If the FDA objects to any of our proposed product brand names, we may
be required to adopt an alternative brand name for our product candidates. If we adopt an alternative brand name, we would lose the benefit of our existing
trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a suitable product
brand name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may be
unable to build a successful brand identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our product
candidates.

If our competitors develop treatments for any of our product candidates’ target indications and those competitor products are approved more quickly,
marketed more successfully or demonstrated to be more effective, the commercial opportunity for our product candidate will be reduced or eliminated.

The biotechnology and pharmaceutical industries are subject to rapid and intense technological change. We face, and will continue to face, competition in
the development and marketing of our product candidates from academic institutions, government agencies, research institutions and biotechnology and
pharmaceutical  companies.  There  can  be  no  assurance  that  developments  by  others  will  not  render  one  or  more  of  our  product  candidates  obsolete  or
noncompetitive. Furthermore, new developments, including the development of other drug technologies and methods of preventing the incidence of disease,
occur in the pharmaceutical industry at a rapid pace. These developments may render one or more of our product candidates obsolete or noncompetitive.

Competitors may seek to develop alternative formulations that do not directly infringe on our in-licensed patent rights. The commercial opportunity for one
or more of our product candidates could be significantly harmed if competitors are able to develop alternative formulations outside the scope of our in-
licensed patents. Compared to us, many of our potential competitors have substantially greater:

●

●

●

●

●

capital resources;

development resources, including personnel and technology;

clinical trial experience;

regulatory experience;

expertise in prosecution of intellectual property rights; and

● manufacturing, distribution and sales and marketing experience.

As  a  result  of  these  factors,  our  competitors  may  obtain  regulatory  approval  of  their  products  more  rapidly  than  we  are  able  to  or  may  obtain  patent
protection or other intellectual property rights that limit our ability to develop or commercialize one or more of our product candidates. Our competitors
may also develop drugs that are more effective, safe, useful and less costly than ours and may be more successful than us in manufacturing and marketing
their products. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large
and established companies. We will also face competition from these third parties in establishing clinical trial sites, in patient registration for clinical trials,
and in identifying and in-licensing new product candidates.

Further, generic therapies are typically sold at lower prices than branded therapies and are generally preferred by hospital formularies and managed care
providers  of  health  services.  We  anticipate  that,  if  approved,  our  product  candidates  will  face  increasing  competition  in  the  form  of  generic  versions  of
branded products of competitors, including those that have lost or will lose their patent exclusivity. In

27

Table of Contents

the future, we may face additional competition from a generic form of our own candidates when the patents covering them begin to expire, or earlier if the
patents are successfully challenged. If we are unable to demonstrate to physicians and payers that the key differentiating features of our product candidates
translate to overall clinical benefit or lower cost of care, we may not be able to compete with generic alternatives.

If any of our product candidates are successfully developed but do not achieve broad market acceptance among physicians, patients, healthcare payors
and the medical community, the revenues that any such product candidates generate from sales will be limited.

Even if our product candidates receive regulatory approval, they may not gain market acceptance among physicians, patients, healthcare payors and the
medical community. Coverage and reimbursement of our product candidates by third-party payors, including government payors, generally would also be
necessary for commercial success. The degree of market acceptance of any approved products would depend on a number of factors, including, but not
necessarily limited to:

●

●

●

●

●

●

●

●

●

●

●

●

●

the efficacy and safety as demonstrated in clinical trials;

the timing of market introduction of such product candidates as well as competitive products;

the clinical indications for which the drug is approved;

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

the potential and perceived advantages of product candidates over alternative treatments;

the safety of product candidates in a broader patient group (i.e. based on actual use);

the cost of treatment in relation to alternative treatments;

the availability of adequate reimbursement and pricing by third parties and government authorities;

changes in regulatory requirements by government authorities for our product candidates

relative convenience and ease of administration;

the prevalence and severity of side effects and adverse events;

the effectiveness of our sales and marketing efforts; and

unfavorable publicity relating to the product.

If any product candidate is approved but does not achieve an adequate level of acceptance by physicians, hospitals, healthcare payors and patients, we may
not generate sufficient revenue from these products and in turn we may not become or remain profitable.

Reimbursement may be limited or unavailable in certain market segments for our product candidates, which could make it difficult for us to sell our
products profitably.

There  is  significant  uncertainty  related  to  the  third-party  coverage  and  reimbursement  of  newly  approved  drugs.  Such  third-party  payors  include
government  health  programs  such  as  Medicare,  managed  care  providers,  private  health  insurers  and  other  organizations.  We  intend  to  seek  approval  to
market our product candidates in the U.S., Europe and other selected foreign jurisdictions. Market acceptance and sales of our product candidates in both
domestic and international markets will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for any of
our product candidates and may be affected by existing and future health care reform measures.

28

Table of Contents

Government and other third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement
for new drugs and, as a result, they may not cover or provide adequate payment for our product candidates. These payors may conclude that our product
candidates are less safe, less effective or less cost-effective than existing or future introduced products, and third-party payors may not approve our product
candidates for coverage and reimbursement or may cease providing coverage and reimbursement for these product candidates.

Obtaining coverage and reimbursement approval for a product from a government or other third-party payor is a time consuming and costly process that
could require us to provide to the payor supporting scientific, clinical and cost-effectiveness data for the use of our products. We may not be able to provide
data sufficient to gain acceptance with respect to coverage and reimbursement. If reimbursement of our future products is unavailable or limited in scope or
amount,  or  if  pricing  is  set  at  unsatisfactory  levels,  it  may  impact  the  market  acceptance  of  our  products  and  we  may  be  unable  to  achieve  or  sustain
profitability.

In  some  foreign  countries,  particularly  in  the  European  Union,  the  pricing  of  prescription  pharmaceuticals  is  subject  to  governmental  control.  In  these
countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product candidate. To
obtain reimbursement or pricing approval in some countries, we may be required to conduct additional clinical trials that compare the cost-effectiveness of
our product candidates to other available therapies. If reimbursement of our product candidates is unavailable or limited in scope or amount in a particular
country, or if pricing is set at unsatisfactory levels, we may be unable to achieve or sustain profitability of our products in such country.

If we are unable to establish sales, marketing, and distribution capabilities or to enter into agreements with third parties to market and sell our product
candidates, we may be unsuccessful in commercializing our product candidates, if they are approved.

We currently do not have a marketing or sales organization for the marketing, sales and distribution of pharmaceutical products. In order to commercialize
any approved product candidate, we would need to build marketing, sales, distribution, managerial and other non-technical capabilities, or arrange for third
parties to perform these services, and we may be unsuccessful in doing so. In the event of successful development and regulatory approval of any of our
current or future product candidates, we expect to build a targeted specialist sales force to market or co-promote the product. There are risks involved with
establishing our own sales, marketing and distribution capabilities. For example, recruiting and training a sales force is expensive and time consuming and
could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is
delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and
our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

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

●
●
●

●

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

We face potential product liability exposure, and if successful claims are brought against us, we may incur substantial liability for one or more of our
product candidates or a future product candidate we may license or acquire and may have to limit their commercialization.

The use of one or more of our product candidates and any future product candidate we may license or acquire in clinical trials and the sale of any products
for which we obtain marketing approval expose us to the risk of product liability claims. For example, we may be sued if any product we develop allegedly
causes injury or is found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include
allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of
warranties. Product liability claims might be brought against us by consumers, health care providers or others using, administering or selling our products.
If we cannot successfully defend

29

Table of Contents

ourselves against these claims, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

● withdrawal of clinical trial participants;
●
●
●
●
●
●
●
●
●

suspension or termination of clinical trial sites or entire trial programs;
decreased demand for any product candidates or products that we may develop;
initiation of investigations by regulators;
impairment of our business reputation;
costs of related litigation;
substantial monetary awards to patients or other claimants;
loss of revenues;
reduced resources of our management to pursue our business strategy; and
the inability to commercialize our product candidate or future product candidates.

We have obtained, and will continue to obtain, limited product liability insurance coverage for any and all of our current and future clinical trials. However,
our  insurance  coverage  may  not  reimburse  us  or  may  not  be  sufficient  to  reimburse  us  for  any  expenses  or  losses  we  may  suffer.  Moreover,  insurance
coverage is becoming increasingly expensive, and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient
amounts to protect us against losses due to liability. If we obtain marketing approval for one or more of our product candidates in development, we intend to
expand  our  insurance  coverage  to  include  the  sale  of  commercial  products,  but  we  may  be  unable  to  obtain  commercially  reasonable  product  liability
insurance  for  any  products  approved  for  marketing.  On  occasion,  large  judgments  have  been  awarded  in  class  action  lawsuits  based  on  drugs  that  had
unanticipated side effects. A successful product liability claim or series of claims brought against us could cause our stock price to fall and, if judgments
exceed our insurance coverage, could decrease our cash and adversely affect our business.

Risks Related to Reliance on Third Parties

We intend to contract with third parties for the manufacture of our approved products, if any. If such contract manufacturer fails to timely produce
sufficient product volume or to comply with applicable regulations, the commercialization of our product candidates may be delayed, we may be unable
to meet market demand, and we may lose potential revenues.

The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing
techniques and process controls, and the use of specialized processing equipment. We intend to enter into development and supply agreements with contract
manufacturers for the completion of pre-commercialization manufacturing development activities and the manufacture of commercial supplies for each of
our product candidates. Any termination or disruption of our relationships with our contract manufacturers may materially harm our business and financial
condition and frustrate any commercialization efforts for each respective product candidate.

All of our contract manufacturers must comply with strictly enforced federal, state and foreign regulations, including cGMP requirements enforced by the
FDA through its establishment inspection program. We are required by law to establish adequate oversight and control over raw materials, components and
finished products furnished by our third-party suppliers and contract manufacturers, but we have little control over their compliance with these regulations.

Any  failure  to  comply  with  applicable  regulations  may  result  in  fines  and  civil  penalties,  suspension  of  production,  restrictions  on  imports  and  exports,
suspension or delay in product approval, product seizure or recall, or withdrawal of product approval, and would limit the availability of our product and
customer confidence in our product. Any manufacturing defect or error discovered after products have been produced and distributed could result in even
more significant consequences, including costly recall procedures, re-stocking costs, potential for breach of contract claims, damage to our reputation and
potential for product liability claims.

If  the  contract  manufacturers  upon  whom  we  rely  to  manufacture  one  or  more  of  our  product  candidates,  and  any  future  product  candidate  we  may  in-
license, fails to deliver the required commercial quantities on a timely basis at commercially reasonable prices, we would likely be unable to meet demand
for our products and we would lose potential revenues.

30

Table of Contents

We  rely,  and  expect  to  continue  to  rely,  on  third  parties  to  conduct  our  preclinical  studies  and  clinical  trials.  Those  third  parties  may  perform
unsatisfactorily, fail to meet deadlines for trial completion, or to comply with applicable regulatory requirements.

We  rely  on  third-party  CROs  and  site  management  organizations  to  conduct  some  of  our  preclinical  studies  and  all  our  clinical  trials  for  our  product
candidates,  and  plan  to  do  the  same  for  any  future  product  candidate.  We  expect  to  continue  to  rely  on  third  parties,  such  as  CROs,  site  management
organizations, image reading vendors, laboratories, clinical data management organizations, medical institutions and clinical investigators, to conduct some
of our preclinical studies and all of our clinical trials. The agreements with these third parties might terminate for a variety of reasons, including a failure to
perform by the third parties. If we need to enter into alternative arrangements, that could delay our product development activities.

Our  reliance  on  these  third  parties  for  research  and  development  activities  reduces  our  control  over  these  activities  but  does  not  relieve  us  of  our
responsibilities. For example, we remain responsible for ensuring that each of our preclinical studies and clinical trials are conducted in accordance with the
general  investigational  plan  and  protocols  for  the  trial  and  for  ensuring  that  our  preclinical  studies  are  conducted  in  accordance  with  good  laboratory
practices (“GLPs”) as appropriate. Moreover, the FDA requires us to comply with standards, commonly referred to as good clinical practices (“GCPs”), for
conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity
and  confidentiality  of  trial  participants  are  protected.  Regulatory  authorities  enforce  these  requirements  through  periodic  inspections  of  trial  sponsors,
clinical  investigators  and  trial  sites.  If  we  or  any  of  our  clinical  research  organizations  or  other  third  party  vendors,  institutions  or  investigators  fail  to
comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory
authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a
regulatory authority, such regulatory authority will determine that any of our clinical trials complies with GCP regulations. In addition, our clinical trials
must be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials,
which would delay the regulatory approval process. We also are required to register ongoing clinical trials and post the results of completed clinical trials on
a  government-sponsored  database,  ClinicalTrials.gov,  within  specified  timeframes.  Failure  to  do  so  can  result  in  fines,  adverse  publicity  and  civil  and
criminal sanctions.

The third parties with whom we have contracted to help perform our preclinical studies and/or clinical trials may also have relationships with other entities,
some of which may be our competitors. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our
preclinical studies or clinical trials in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in
obtaining,  marketing  approvals  for  our  product  candidates  and  will  not  be  able  to,  or  may  be  delayed  in  our  efforts  to,  successfully  commercialize  our
product candidates.

If any of our relationships with these third-party CROs or site management organizations terminate, we may not be able to enter into arrangements with
alternative  CROs  or  site  management  organizations  or  to  do  so  on  commercially  reasonable  terms.  Switching  or  adding  additional  CROs  or  site
management organizations involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new
CRO  or  site  management  organization  commences  work.  As  a  result,  delays  could  occur,  which  could  compromise  our  ability  to  meet  our  desired
development timelines. Though we carefully manage our relationships with our CROs or site management organizations, there can be no assurance that we
will not encounter similar challenges or delays in the future. Forces beyond our control, including the impacts of COVID-19, could disrupt the ability of our
third-party CROs, site management organizations, image reading vendors, laboratories, clinical data management organizations, medical institutions and
clinical investigators to conduct our preclinical studies and our clinical trials for our product candidates and for any future product candidate.

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

We do not have any manufacturing facilities. We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for
preclinical and clinical testing, and plan to do so for commercial manufacture of any of our product candidates that may receive marketing approval. This
reliance  on  third  parties  increases  the  risk  that  we  will  not  have  sufficient  quantities  of  our  product  candidates  or  any  future  product  candidate  or  such
quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts.

31

We also expect to rely on third-party manufacturers or third-party collaborators for the manufacture of commercial supply of any product candidates for
which our collaborators or we may obtain marketing approval. We may be unable to establish or maintain any agreements with third-party manufacturers
or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails
additional risks, including:

●

reliance on the third party for regulatory compliance and quality assurance, while still being required by law to establish adequate oversight and
control over products furnished by that third party;
the possible breach of the manufacturing agreement by the third party;

●
● manufacturing delays if our third-party manufacturers are unable to obtain raw materials due to supply chain disruptions, give greater priority to the
supply of other products over our product candidates or otherwise do not satisfactorily perform according to the terms of the agreement between us;
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.

●
●

We rely on our third-party manufacturers to produce or purchase from third-party suppliers the materials necessary to produce our product candidates for
our preclinical and clinical trials. There are a limited number of suppliers for raw materials that we use to manufacture our drugs and there may be a need to
assess alternate suppliers to prevent a possible disruption of the manufacture of the materials necessary to produce our product candidates for our preclinical
and clinical trials, and if approved, ultimately for commercial sale. We do not have any control over the process or timing of the acquisition of these raw
materials by our third-party manufacturers. Forces beyond our control, including the effects of the COVID-19 pandemic, could disrupt the global supply
chain and impact our or our third-party manufacturers’ ability to obtain raw materials or other products necessary to manufacture our product candidates.
Any significant delay in the supply of a product candidate, or the raw material components thereof, for an ongoing preclinical or clinical trial due to the
need to replace a third-party manufacturer could considerably delay completion of our preclinical or clinical trials, product testing and potential regulatory
approval of our product candidates. If our third-party manufacturers or we are unable to purchase these raw materials after regulatory approval has been
obtained for a product candidate, the commercial launch of that product candidate would be delayed or there would be a shortage in supply, which would
impair our ability to generate revenues from the sale of our product candidates.

The facilities used by our third-party manufacturers to manufacture our product candidates must be approved by the FDA pursuant to inspections that will
be  conducted  after  we  submit  an  NDA  or  BLA  to  the  FDA.  We  are  required  by  law  to  establish  adequate  oversight  and  control  over  raw  materials,
components and finished products furnished by our third-party manufacturers, but we do not control the day-to-day manufacturing operations of, and are
dependent on, our third-party manufacturers for compliance with cGMP regulations for manufacture of our product candidates. Third-party manufacturers
may not be able to comply with the cGMP regulations or similar regulatory requirements outside the United States. Our failure, or the failure of our third-
party  manufacturers,  to  comply  with  applicable  regulations  could  result  in  sanctions  being  imposed  on  us,  including  clinical  holds,  fines,  injunctions,
restrictions  on  imports  and  exports,  civil  penalties,  delays,  suspension  or  withdrawal  of  approvals,  license  revocation,  seizures  or  recalls  of  product
candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our products.

One or more of the product candidates that we may develop may compete with other product candidates and products for access to manufacturing facilities.
There are a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. Any performance
failure on the part of our existing or future third-party manufacturers could delay clinical development or marketing approval. We do not currently have
arrangements  in  place  for  redundant  supply  or  a  second  source  for  bulk  drug  substance  or  the  manufacture  of  drug  product.  If  our  current  third-party
manufacturers  cannot  perform  as  agreed,  we  may  be  required  to  replace  such  manufacturers.  We  may  incur  added  costs  and  delays  in  identifying  and
qualifying any replacement manufacturers.

The U.S. DEA restricts the importation of a controlled substance finished drug product when the same substance is commercially available in the United
States, which could reduce the number of potential alternative manufacturers for one or more of our product candidates.

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

32

Table of Contents

We  also  expect  to  rely  on  other  third  parties  to  store  and  distribute  drug  supplies  for  our  clinical  trials. Any  performance  failure  on  the  part  of  our
distributors could delay clinical development or marketing approval of our product candidates or commercialization of our products, if approved, producing
additional losses and depriving us of potential product revenue.

We rely on clinical data and results obtained by third parties that could ultimately prove to be inaccurate or unreliable.

As  part  of  our  strategy  to  mitigate  development  risk,  we  seek  to  develop  product  candidates  with  well-studied  mechanisms  of  action  and  may  utilize
biomarkers to assess potential clinical efficacy early in the development process. This strategy necessarily relies upon clinical data and other results obtained
by  third  parties  that  may  ultimately  prove  to  be  inaccurate  or  unreliable.  Further,  such  clinical  data  and  results  may  be  based  on  products  or  product
candidates that are significantly different from our product candidates or any future product candidate. If the third-party data and results we rely upon prove
to be inaccurate, unreliable or not applicable to our product candidates or future product candidate, we could make inaccurate assumptions and conclusions
about our product candidates and our research and development efforts could be compromised.

Risks Relating to Legislation and Regulation Affecting the Biopharmaceutical and Other Industries

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 cannot predict the likelihood, nature or extent of how government regulation that may arise from future legislation or administrative or executive action
taken by the U.S. presidential administration may impact our business and industry. In particular, the U.S. President has taken several executive actions,
specifically  through  rulemaking  and  guidance,  that  could  impact  the  pharmaceutical  business  and  industry. A  few  of  the  major  administrative  actions
include:

1. On  October  9,  2019,  the  Centers  for  Medicare  &  Medicaid  Services  (“CMS”)  issued  a  proposed  rule  entitled, Modernizing  and  Clarifying  the
Physician  Self-Referral  Regulations  and  on  the  same  day  the  HHS  Office  of  Inspector  General  issued  a  similar  rule,  entitled Revisions  to  Safe
Harbors Under the Anti-Kickback Statute, and Civil Monetary penalty Rules Regarding Beneficiary Inducements. The proposed rules are an effort
to reform regulations dealing with anti-kickback and self-referral laws. The proposals are attempting to allow certain financial arrangements that
would  otherwise  violate  anti-kickback  and  self-referral  laws  for  providers  that  are  participating  in  value-based  payment  arrangements.  The
proposed rule could impact drug purchasing behavior to ensure providers are within their budget and/or restructure existing payment structures
between providers and manufacturers.

2. On  October  30,  2019,  the Administration  issued  an  advanced  notice  of  proposed  rulemaking  (“ANPRM”)  entitled, International  Pricing  Index
Model for Medicare Part B Drugs. This ANPRM is soliciting feedback on a potential proposal to align United States drug prices in the Medicare
Part B program with international prices. It also solicits public feedback on a policy that would allowing private-sector vendors to negotiate prices,
take title to drugs, and improve competition for hospital and physician business. Although this is only a notice for a potential rule, it signals the
Administration’s desire to regulatorily influence the United States drug pricing system that could adversely affect the industry.

3. On November 15, 2019, CMS issued a proposed rule entitled, Transparency in Coverage and finalized the Calendar Year (“CY”) 2020 Outpatient
Prospective  Payment  System  (“OPPS”)  &  Ambulatory  Surgical  Center  Price  Transparency  Requirements  for  Hospitals  to  Make  Standard
Charges Rule. Together the rules would increase price transparency through health plans and in hospitals. The affects may influence consumer
purchasing habits in the health care sector as a whole. Although the transparency provisions are not yet in effect and the hospital price transparency
requirements are subject to litigation, there could be implications for the industry related to drug pricing if or when it is enacted.

4. On  November  18,  2019,  CMS  issued  a  proposed  rule  entitled, Medicaid Fiscal Accountability Regulation (“MFAR”).  The  proposed  rule  would
significantly  impact  states’  ability  to  finance  their  Medicaid  programs.  If  finalized,  the  MFAR  could  force  states  to  restructure  their  Medicaid
financing that could disincentivize or change state prescription drug purchasing behavior that would adversely impact the industry.

33

5. On  December  18,  2019,  the  FDA  issued  a  proposed  rule  entitled, Importation  of  Prescription  Drugs.  The  proposed  rule  would  allow  the
importation  of  certain  prescription  drugs  from  Canada.  If  finalized,  states  or  other  non-federal  government  entities  would  be  able  to  submit
importation program proposals to FDA for review and authorization. This proposed rule could also influence pricing practices in the United States.

6. On January 30, 2020, CMS issued a state waiver option entitled, Health Adult Opportunity (“HAO”). The HAO would allow states to restructure
benefits  and  coverage  policies  for  their  Medicaid  programs.  The  HAO  will  provide  states  administrative  flexibilities  in  exchange  for  a  capped
federal share. The cap on the federal share is commonly referred to as a “block grant.” Importantly, the HAO allows states to set formularies that
align with Essential Health Benefit requirements while still requiring manufacturers to participate in the Medicaid Rebate Program. Depending on
utilization of the HAO by states, it could impact the industry – especially if states elect to use a formulary.

We are subject to new legislation, regulatory proposals and managed care initiatives that may increase our costs of compliance and adversely affect our
ability to market our products, obtain collaborators and raise capital.

In the U.S. and some foreign jurisdictions, there have been a number of proposed and enacted legislative and regulatory changes regarding the healthcare
system that could prevent or delay marketing approval of one or more of our product candidates, restrict or regulate post-approval activities and affect our
ability to profitably sell any of our product candidates for which we obtain marketing approval. Among policy makers and payors in the U.S. and elsewhere,
there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and expanding
access.  In  the  U.S.,  the  pharmaceutical  industry  has  been  a  particular  focus  of  these  efforts  and  has  been  significantly  affected  by  major  legislative
initiatives.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the “ACA”), was
enacted  in  2010  and  made  significant  changes  to  the  United  States’  healthcare  system.  The ACA  and  any  revisions  or  replacements  of  that Act,  any
substitute legislation, and other changes in the law or regulatory framework could have a material adverse effect on our business.

Among the provisions of the ACA of importance to our potential product candidates are:

●

●

●

●

●

●

●

●
●
●

●

an  annual,  nondeductible  fee  on  any  entity  that  manufactures,  or  imports  specified  branded  prescription  drugs  and  biologic  agents,  apportioned
among these entities according to their market share in certain government healthcare programs;
an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average
manufacturer price for branded and generic drugs, respectively;
expansion  of  healthcare  fraud  and  abuse  laws,  including  the  federal  False  Claims Act  and  the  federal Anti-Kickback  Statute,  new  government
investigative powers and enhanced penalties for non-compliance;
a  new  Medicare  Part  D  coverage  gap  discount  program,  in  which  manufacturers  must  agree  to  offer  70%  point-of-sale  discounts  off  negotiated
prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for a manufacturer’s outpatient drugs to be
covered under Medicare Part D;
extension  of  a  manufacturer’s  Medicaid  rebate  liability  to  covered  drugs  dispensed  to  individuals  who  are  enrolled  in  Medicaid  managed  care
organizations;
expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals
and  by  adding  new  mandatory  eligibility  categories  for  certain  individuals  with  income  at  or  below  138%  of  the  federal  poverty  level,  thereby
potentially increasing a manufacturer’s Medicaid rebate liability;
expansion  of  the  entities  eligible  to  enroll  in  the  340B  Drug  Pricing  Program  to  include  certain  critical  access  hospitals,  freestanding  cancer
hospitals, rural referral centers, and sole community hospitals, but exempting orphan drugs from the ceiling price requirements for these covered
entities;
the new requirements under the federal Open Payments program and its implementing regulations;
a new requirement to annually report drug samples that manufacturers and distributors provide to physicians;
a new regulatory pathway for the approval of biosimilar biological products, all of which will impact existing government healthcare programs and
will result in the development of new programs; 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  Supreme  Court  upheld  the ACA  in  the  main  challenge  to  the  constitutionality  of  the  law  in  2012.  Specifically,  the  Supreme  Court  held  that  the
individual mandate and corresponding penalty was constitutional because it would be considered a tax by the federal government. The Supreme Court also
upheld federal subsidies for purchasers of insurance through federally facilitated exchanges in a decision released in June 2015.

At the end of 2017, Congress passed the Tax Cuts and Jobs Act, which repealed the penalty for individuals who fail to maintain minimum essential health
coverage  as  required  by  the ACA.  Following  this  legislation,  Texas  and  19  other  states  filed  a  lawsuit  alleging  that  the ACA  is  unconstitutional  as  the
individual mandate was repealed, undermining the legal basis for the Supreme Court’s prior decision. On December 14, 2018, a Texas federal district court
judge  issued  a  ruling  declaring  that  the ACA  in  its  entirety  is  unconstitutional.  Upon  appeal,  the  Fifth  Circuit  upheld  the  district  court’s  ruling  that  the
individual mandate is unconstitutional. However, the Fifth Circuit remanded the case back to the district court to conduct a more thorough assessment of the
constitutionality of the entire ACA despite the individual mandate being unconstitutional. The Supreme Court agreed to hear the case on appeal from the
Fifth  Circuit  on  March  2,  2020  and  held  oral  arguments  on  November  10,  2020.  While  this  lawsuit  has  no  immediate  legal  effect  on  the ACA  and  its
provisions, this lawsuit is ongoing and the outcome may have a significant impact on our business.

The Bipartisan Budget Act of 2018, the “BBA,” which set government spending levels for Fiscal Years 2018 and 2019, revised certain provisions of the
ACA.  Specifically,  beginning  in  2019,  the  BBA  increased  manufacturer  point-of-sale  discounts  off  negotiated  prices  of  applicable  brand  drugs  in  the
Medicare Part D coverage gap from 50% to 70%, ultimately increasing the liability for brand drug manufacturers. Further, this mandatory manufacturer
discount applied to biosimilars beginning in 2019.

The Senate Committee on Health, Education, Labor, and Pensions (HELP) advanced the Lower Health Care Costs Act of 2019. Among other things, the
bill is intended to reduce costs in the United States health sector. The bill revises certain requirements to expedite the approval of generics and biosimilars.
It also limits prices that pharmacy benefit managers may charge health insurers or enrollees for prescription drugs. Although this bill still needs to pass the
full Senate and House of Representatives, it is worth noting the wide-ranging effects it could have on the health care sector.

On December 12, 2019, the House of Representatives passed broad legislation (H.R. 3, the Elijah E. Cummings Lower Drug Costs Now Act) that would,
among other provisions, require HHS to negotiate drug prices and impose price caps and restructure the Medicare Part D benefit, imposing more financial
responsibility on certain drug manufacturers. Failure by a manufacturer to reach an agreement with HHS on the negotiated price could result in significant
penalties  for  prescription  drug  manufacturers.  In  addition,  S.  2543,  the  Prescription  Drug  Pricing  Reduction Act  would  also,  among  other  provisions,
restructure the Medicare Part D benefit, but it would not authorize direct negotiation by the federal government. While we cannot predict what proposals
may ultimately become law, the elements under consideration could significantly change the landscape in which the pharmaceutical market operates.

The Trump Administration took several regulatory steps to redirect ACA implementation. The HHS finalized a Medicare hospital payment reduction for
Part B drugs acquired through the 340B Drug Pricing Program.

Under  the  Trump  Administration,  HHS  finalized  several  proposals  aimed  at  lowering  drug  prices  for  Medicare  beneficiaries  and  increasing  price
transparency. For example, the Trump Administration issued an interim final rule on November 27, 2020 implementing a “Most Favored Nation” payment
model for Part B drugs that applies international reference pricing to determine reimbursement for certain drugs paid by Medicare Part B. The interim final
rule was enjoined by federal courts prior to its implementation date of January 1, 2021, and the lawsuit is ongoing. In addition, HHS, in conjunction with
the FDA, finalized four pharmaceutical importation pathways in September 2020: (1) regulations establishing importation of pharmaceuticals from Canada
by  wholesalers  and  pharmacists;  (2)    FDA  guidance  permitting  manufacturers  to  import  their  own  pharmaceuticals  that  were  originally  intended  for
marketing in other countries; (3) a request for proposals from private sector entities to import prescription drugs for personal use under existing statutory
authority; and (4) a request for proposals from private sector entities to reimport insulin under existing statutory authority. Further, on November 11, 2020,
the Trump Administration issued a final rule that changes the permissible structure of drug rebates and discounts between drug manufacturers and third-
party payors (including pharmacy benefit managers that negotiate drug prices on behalf of such third-party payors). This final rule, often referred to as the
“Rebate  Rule,”  could  have  significant  direct  and  indirect  impacts  on  drug  pricing  in  both  government  and  commercial  markets.  With  respect  to  price
transparency,  the  Trump Administration  promulgated  regulations  that  require  hospitals  and  third-party  payors  to  disclose  prices  of  items  and  services,
which may impact negotiated rates in the commercial market.

On January 20, 2021, Joe Biden was inaugurated as the 46th president of the United States. As a presidential candidate, Mr. Biden indicated support for
several policies aimed at lowering drug prices, including government price negotiation, drug importation,

35

Table of Contents

international reference pricing, and price increase controls. The incoming Biden Administration may continue, modify, or repeal many of the drug pricing
policies proposed and finalized by the Trump Administration. While we cannot predict which policies the Biden Administration may support and enforce,
the  policies  finalized  in  the  months  prior  to  the  beginning  of  Mr.  Biden’s  term,  if  continued,  could  significantly  change  the  landscape  in  which  the
pharmaceutical market operates and significantly impact our ability to effectively market and sell our products.

There likely will continue to be legislative and regulatory proposals at the federal and state levels directed at broadening the availability of healthcare and
containing or lowering the cost of healthcare products and services. We cannot predict the initiatives that may be adopted in the future. The continuing
efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare
may adversely affect:

●

●

●

●

●

the demand for any products for which we may obtain regulatory approval;

our ability to set a price that we believe is fair for our products;

our ability to generate revenues and achieve or maintain profitability;

the level of taxes that we are required to pay; and

the availability of capital.

In addition, governments may impose price controls, which may adversely affect our future profitability. In January 2020, President Trump signed into law
the U.S.-Mexico-Canada (USMCA) trade deal into law. As enacted, there are no commitments with respect to biological product intellectual property rights
or data protection, which may create an unfavorable environment across these three countries.

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

Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription
of  any  product  candidates  for  which  we  obtain  marketing  approval.  Our  future  arrangements  with  third-party  payors  and  customers  may  expose  us  to
broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations,  including,  without  limitation,  the  federal Anti-Kickback  Statute  and  the
federal False Claims Act, which may constrain the business or financial arrangements and relationships through which we sell, market and distribute any
product candidates for which we obtain marketing approval. In addition, we may be subject to transparency laws and patient privacy regulation by U.S.
federal  and  state  governments  and  by  governments  in  foreign  jurisdictions  in  which  we  conduct  our  business.  The  applicable  federal,  state  and  foreign
healthcare laws and regulations that may affect our ability to operate include:

●

●

the  federal Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,    offering,  receiving  or
providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for,  either the referral of an individual for, or the
purchase, order or recommendation of, any good or service, for which payment may be made under federal and state healthcare programs, such as
Medicare and Medicaid;
federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act, which impose criminal and civil
penalties, including civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the
federal government, including the Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to
avoid, decrease or conceal an obligation to pay money to the federal government; the federal Health Insurance Portability and Accountability Act of
1996  (“HIPAA”),  which  imposes  criminal  and  civil  liability  for  executing  a  scheme  to  defraud  any  healthcare  benefit  program  or  making  false
statements relating to healthcare matters;

● HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health Act  of  2009  (“HITECH”),    and  their  respective

implementing regulations, which impose obligations on covered healthcare providers, health plans, and

36

healthcare clearinghouses, as well as their business associates that create, receive, maintain or transmit individually identifiable health information
for  or  on  behalf  of  a  covered  entity,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of  individually  identifiable  health
information;
the federal Open Payments program,  which  requires  manufacturers  of  certain  approved  drugs,  devices,  biologics  and  medical  supplies  for  which
payment  is  available  under  Medicare,  Medicaid  or  the  Children’s  Health  Insurance  Program,  with  specific  exceptions,  to  report  annually  to  the
Centers for Medicare & Medicaid Services (“CMS”), information related to “payments or other transfers of value” made to physicians, which is
defined to include doctors, dentists, optometrists, podiatrists and chiropractors, and teaching hospitals and applicable manufacturers and applicable
group purchasing organizations to report annually to CMS ownership and investment interests held by the physicians and their immediate family
members. Data collection began on August 1, 2013 with requirements for manufacturers to submit reports to CMS by March 31, 2014 and 90 days
after  the  end  each  subsequent  calendar  year.  Disclosure  of  such  information  was  made  by  CMS  on  a  publicly  available  website  beginning  in
September 2014; and
analogous  state  and  foreign  laws  and  regulations,  such  as  state  anti-kickback  and  false  claims  laws,  which  may  apply  to  sales  or  marketing
arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-governmental  third-  party  payors,  including  private  insurers;
state and foreign laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the
relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers; state
and  foreign  laws  that  require  drug  manufacturers  to  report  information  related  to  payments  and  other  transfers  of  value  to  physicians  and  other
healthcare  providers  or  marketing  expenditures;  and  state  and  foreign  laws  governing  the  privacy  and  security  of  health  information  in  certain
circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance
efforts.

Efforts  to  ensure  that  our  business  arrangements  with  third  parties  will  comply  with  applicable  healthcare  laws  and  regulations  may  involve  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 civil, criminal and administrative penalties, including, without
limitation,  damages,  fines,  imprisonment,  exclusion  from  participation  in  government  healthcare  programs,  such  as  Medicare  and  Medicaid,  and  the
curtailment  or  restructuring  of  our  operations,  which  could  have  a  material  adverse  effect  on  our  business.  If  any  of  the  physicians  or  other  healthcare
providers or entities with whom we expect to do business, including our collaborators, is found not to be in compliance with applicable laws, it may be
subject  to  criminal,  civil  or  administrative  sanctions,  including  exclusions  from  participation  in  government  healthcare  programs,  which  could  also
materially affect our business.

Risks Related to Intellectual Property and Potential Disputes with Licensors Thereof

If we are unable to obtain and maintain sufficient patent protection for our technology and products, our competitors could develop and commercialize
technology and products similar or identical to ours, and our ability to successfully commercialize our technology and products may be impaired.

Our  commercial  success  will  depend  in  part  on  obtaining  and  maintaining  patent  protection  and  trade  secret  protection  in  the  United  States  and  other
countries with respect to our product candidates or any future product candidate that we may license or acquire and the methods we use to manufacture
them, as well as successfully defending these patents and trade secrets against third-party challenges. We seek to protect our proprietary position by filing
patent  applications  in  the  United  States  and  abroad  related  to  our  novel  technologies  and  product  candidates,  and  by  maintenance  of  our  trade  secrets
through proper procedures. We will only be able to protect our technologies from unauthorized use by third parties to the extent that valid and enforceable
patents or trade secrets cover them in the market they are being used or developed.

The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications
at a reasonable cost or in a timely manner. It is also possible that we will fail to identify any patentable aspects of our research and development output and
methodology, and, even if we do, an opportunity to obtain patent protection may have passed. Given the uncertain and time-consuming process of filing
patent applications and prosecuting them, it is possible that our product(s) or process(es) originally covered by the scope of the patent application may have
changed or been modified, leaving our product(s) or process(es) without patent protection. If our licensors or we fail to obtain or maintain patent protection
or  trade  secret  protection  for  one  or  more  product  candidates  or  any  future  product  candidate  we  may  license  or  acquire,  third  parties  may  be  able  to
leverage our

37

proprietary information and products without risk of infringement, which could impair our ability to compete in the market and adversely affect our ability
to generate revenues and achieve profitability. Moreover, should we enter into other collaborations we may be required to consult with or cede control to
collaborators regarding the prosecution, maintenance and enforcement of licensed patents. Therefore, 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.  In  addition,  no  consistent  policy  regarding  the  breadth  of  claims  allowed  in  pharmaceutical  or
biotechnology patents has emerged to date in the U.S. The patent situation outside the U.S. is even more uncertain. The laws of foreign countries may not
protect our rights to the same extent as the laws of the United States, and we may fail to seek or obtain patent protection in all major markets. For example,
European patent law restricts the patentability of methods of treatment of the human body more than United States law does. 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 a first filing, or in some cases not at all. Therefore, we cannot know with certainty whether we or our licensors were the first to make
the  inventions  claimed  in  patents  or  pending  patent  applications  that  we  own  or  licensed,  or  that  we  or  our  licensors  were  the  first  to  file  for  patent
protection of such inventions. In the event that a third party has also filed a U.S. patent application relating to our product candidates or a similar invention,
depending  upon  the  priority  dates  claimed  by  the  competing  parties,  we  may  have  to  participate  in  interference  proceedings  declared  by  the  USPTO  to
determine  priority  of  invention  in  the  U.S.  The  costs  of  these  proceedings  could  be  substantial  and  it  is  possible  that  our  efforts  to  establish  priority  of
invention would be unsuccessful, resulting in a material adverse effect on our U.S. patent position. As a result, the issuance, scope, validity, enforceability
and commercial value of our or any of our respective licensors’ 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. For example, the federal courts of the United States have taken an increasingly dim view
of the patent eligibility of certain subject matter, such as naturally occurring nucleic acid sequences, amino acid sequences and certain methods of utilizing
the same, which include their detection in a biological sample and diagnostic conclusions arising from their detection. Such subject matter, which had long
been a staple of the biotechnology and biopharmaceutical industry to protect their discoveries, is now considered, with few exceptions, ineligible in the first
instance for protection under the patent laws of the United States. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in
our patents or in those licensed from a third-party.

In  addition,  U.S.  patent  laws  may  change,  which  could  prevent  or  limit  us  from  filing  patent  applications  or  patent  claims  to  protect  products  and/or
technologies or limit the exclusivity periods that are available to patent holders, as well as affect the validity, enforceability, or scope of issued patents.

Moreover,  we  may  be  subject  to  a  third-party  pre-issuance  submission  of  prior  art  to  the  USPTO,  or  become  involved  in  opposition,  derivation,
reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of others. The costs of
these  proceedings  could  be  substantial  and  it  is  possible  that  our  efforts  to  establish  priority  of  invention  would  be  unsuccessful,  resulting  in  a  material
adverse effect on our U.S. patent position. An adverse determination in any such submission, patent office trial, proceeding or litigation could reduce the
scope of, render unenforceable, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with
us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if the
breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to
license, develop or commercialize current or future product candidates.

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

The issuance of a patent does not foreclose challenges to its inventorship, scope, validity or enforceability. Therefore, our owned and licensed patents may
be challenged in the courts or patent offices in the United States and abroad. 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 product candidates might expire before or shortly after such
product candidates are commercialized.

38

Table of Contents

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.

We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available on commercially
reasonable terms.

A  third  party  may  hold  intellectual  property,  including  patent  rights  that  are  important  or  necessary  to  the  development  and  commercialization  of  our
products. It may be necessary for us to use the patented or proprietary technology of third parties, whom may or may not be interested in granting such a
license, to commercialize our products, in which case we would be required to obtain a license from these third parties on commercially reasonable terms,
or our business could be harmed, possibly materially.

We  depend  on  our  licensors  to  maintain  and  enforce  the  intellectual  property  covering  certain  of  our  product  candidates.  We  have  limited,  if  any,
control over the resources that our licensors can or will devote to securing, maintaining, and enforcing patents protecting our product candidates.

We  depend  on  our  licensors  to  protect  the  proprietary  rights  covering  our  antibody  and  certain  of  our  small  molecule  product  candidates  and  we  have
limited, if any, control over the amount or timing of resources that they devote on our behalf, or the priority they place on, maintaining patent rights and
prosecuting patent applications to our advantage. Moreover, we have limited, if any, control over the strategies and arguments employed in the maintenance
of patent rights and the prosecution of patent applications to our advantage.

Our licensors, depending on the patent or application, are responsible for maintaining issued patents and prosecuting patent applications for our antibody
and certain of our small molecule product candidates. We cannot be sure that they will perform as required. Should they decide they no longer want to
maintain any of the patents licensed to us, they are required to afford us the opportunity to do so at our expense. If our licensors do not perform, and if we
do not assume the maintenance of the licensed patents in sufficient time to make required payments or filings with the appropriate governmental agencies,
we risk losing the benefit of all or some of those patent rights. Moreover, and possibly unbeknownst to us, our licensors may experience serious difficulties
related to their overall business or financial stability, and they may be unwilling or unable to continue to expend the financial resources required to maintain
and prosecute these patents and patent applications. While we intend to take actions reasonably necessary to enforce our patent rights, we depend, in part,
on our licensors to protect a substantial portion of our proprietary rights and to inform us of the status of those protections and efforts thereto.

Our licensors may also be notified of alleged infringement and be sued for infringement of third-party patents or other proprietary rights. We may have
limited,  if  any,  control  or  involvement  over  the  defense  of  these  claims,  and  our  licensors  could  be  subject  to  injunctions  and  temporary  or  permanent
exclusionary  orders  in  the  U.S.  or  other  countries.  Our  licensors  are  not  obligated  to  defend  or  assist  in  our  defense  against  third-party  claims  of
infringement. We have limited, if any, control over the amount or timing of resources, if any, that our licensors devote on our behalf or the priority they
place on defense of such third-party claims of infringement.

Because of the uncertainty inherent in any patent or other litigation involving proprietary rights, we or our licensors may not be successful in defending
claims of intellectual property infringement alleged by third parties, which could have a material adverse effect on our results of operations. Regardless of
the outcome of any litigation, defending the litigation may be expensive, time-consuming and distracting to management.

Protecting our proprietary rights is difficult and costly, and we may be unable to ensure their protection.

The degree of future protection for our proprietary rights is uncertain, because legal means afford only limited protection and may not adequately protect
our rights or permit us to gain or keep our competitive advantage, in addition to being costly and time consuming to undertake. For example:

●
●
●

●

our licensors might not have been the first to make the inventions covered by each of our pending patent applications and issued patents;
our licensors might not have been the first to file patent applications for these inventions;
others  may  independently  develop  similar  or  alternative  technologies  or  duplicate  our  product  candidates  or  any  future  product  candidate
technologies;
it is possible that none of the pending patent applications licensed to us will result in issued patents;

39

Table of Contents

●
●

the scope of our issued patents may not extend to competitive products developed or produced by others;
the  issued  patents  covering  our  product  candidates  or  any  future  product  candidate  may  not  provide  a  basis  for  market  exclusivity  for  active
products, may not provide us with any competitive advantages, or may be challenged by third parties;

● we may not develop additional proprietary technologies that are patentable; or
●

intellectual property rights of others may have an adverse effect on our business.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and
unsuccessful, and an unfavorable outcome in any litigation would harm our business.

Competitors may infringe our issued patents or other intellectual property. To counter infringement or unauthorized use, we may be required to file one or
more actions for patent infringement, which can be expensive and time consuming. Any claims we assert against accused infringers could provoke these
parties to assert counterclaims against us alleging invalidity of our patents or that we infringe their patents; or provoke those parties to petition the USPTO
to institute inter partes review against the asserted patents, which may lead to a finding that all or some of the claims of the patent are invalid. 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 pending patents at risk of being invalidated, rendered unenforceable, or interpreted
narrowly.  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. Furthermore, adverse results on U.S. patents may affect related
patents in our global portfolio.

Our ability to develop, manufacture, market and sell one or more of our product candidates or any future product candidate that we may license or acquire
depends  upon  our  ability  to  avoid  infringing  the  proprietary  rights  of  third  parties.  Numerous  U.S.  and  foreign  issued  patents  and  pending  patent
applications, which are owned by third parties, exist in the general fields of fully human immuno-oncology targeted antibodies and targeted anti-cancer
agents  and  cover  the  use  of  numerous  compounds  and  formulations  in  our  targeted  markets.  Because  of  the  uncertainty  inherent  in  any  patent  or  other
litigation involving proprietary rights, we and our licensors may not be successful in defending intellectual property claims asserted by third parties, which
could have a material adverse effect on our results of operations. Regardless of the outcome of any litigation, defending the litigation may be expensive,
time-consuming  and  distracting  to  management.  In  addition,  because  patent  applications  can  take  many  years  to  issue,  there  may  be  currently  pending
applications that are unknown to us, which may later result in issued patents that one or more of our product candidates may infringe. There could also be
existing patents of which we are not aware that one or more of our product candidates may infringe, even if only inadvertently.

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

There  is  a  substantial  amount  of  litigation  involving  patent  and  other  intellectual  property  rights  in  the  biotechnology  and  biopharmaceutical  industries
generally. If a third-party claims that we infringe their patents or misappropriated their technology, we could face a number of issues, including:

●

●
●
●

infringement and other intellectual property claims which, with or without merit, can be expensive and time consuming to litigate and can divert
management’s attention from our core business;
substantial damages for past infringement which we may have to pay if a court decides that our product infringes a competitor’s patent;
a court prohibiting us from selling or licensing our product unless the patent holder licenses the patent to us, which it would not be required to do;
if a license is available from a patent holder, we may have to pay substantial royalties or grant cross licenses to our patents; and

40

Table of Contents

●

redesigning our processes so they do not infringe, which may not be possible or could require substantial funds, time, and may result in an inferior
or less-desirable process or product.

If we fail to comply with our obligations under our intellectual property licenses and third-party funding arrangements, we could lose rights that are
important to our business.

We have in-licensed the rights to all of our product candidates from third parties. Any disputes between us and any of our licensors regarding our rights
under our license agreements may impact our ability to develop and commercialize these product candidates. Any uncured, material breach under any of
our license agreements could result in our loss of exclusive rights to one or more of our product candidates and may lead to a complete termination of our
related product development efforts.

We  are  currently  a  party  to  license  agreements  with  Dana-Farber, Adimab,  NeuPharma  and  Jubilant.  In  the  future,  we  may  become  party  to  additional
licenses that are important for product development and commercialization. If we fail to comply with our obligations under current or future license and
funding agreements, our counterparties may have the right to terminate these agreements, in which event we might not be able to develop, manufacture or
market any product or utilize any technology that is covered by these agreements or may face other penalties under the agreements. Such an occurrence
could  materially  and  adversely  affect  the  value  of  a  product  candidate  being  developed  under  any  such  agreement  or  could  restrict  our  drug  discovery
activities. Termination of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or
reinstated agreements with less favorable terms, or cause us to lose our rights under these agreements, including our rights to important intellectual property
or technology.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As  is  common  in  the  biotechnology  and  pharmaceutical  industry,  we  employ  individuals  who  were  previously  employed  at  other  biotechnology  or
pharmaceutical companies, including our competitors or potential competitors. Although no claims against us are currently pending, we may be subject to
claims  that  we  or  these  employees  have  inadvertently  or  otherwise  used  or  disclosed  trade  secrets  or  other  proprietary  information  of  their  former
employers. Even if frivolous or unsubstantiated in nature, litigation may be necessary to defend against these claims. Even if we are successful in defending
against these claims, litigation could result in substantial costs and be a distraction to management and the implicated employee(s).

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

In  addition  to  seeking  patent  protection  for  our  product  candidates  or  any  future  product  candidate,  we  also  rely  on  trade  secrets,  including  unpatented
know-how, technology and other proprietary information, to maintain our competitive position, particularly where we do not believe patent protection is
appropriate or obtainable. However, trade secrets are difficult to protect. We limit disclosure of such trade secrets where possible but we also seek to protect
these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who do have access to them, such as our employees,
our licensors, corporate collaborators, outside scientific collaborators, contract manufacturers, consultants, advisors and other third parties. We also enter
into  confidentiality  and  invention  or  patent  assignment  agreements  with  our  employees  and  consultants.  Despite  these  efforts,  any  of  these  parties  may
breach the agreements and may unintentionally or willfully 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. Moreover, 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.

Risks Relating to Our Platform and Data

Our business and operations would suffer in the event of computer system failures, cyber-attacks, or deficiencies in our or third parties’ cybersecurity.

We are increasingly dependent upon information technology systems, infrastructure, and data to operate our business. In the ordinary course of business,
we  collect,  store,  and  transmit  confidential  information,  including,  but  not  limited  to,  information  related  to  our  intellectual  property  and  proprietary
business information, personal information, and other confidential information. It is critical that we

41

Table of Contents

maintain  such  confidential  information  in  a  manner  that  preserves  its  confidentiality  and  integrity.  Furthermore,  we  have  outsourced  elements  of  our
operations to third party vendors, who each have access to our confidential information, which increases our disclosure risk.

Although  we  have  implemented  internal  security  and  business  continuity  measures  and  have  developed  an  information  technology  infrastructure,  our
internal  computer  systems,  as  well  as  those  of  current  and  future  third  parties  on  which  we  rely,  are  vulnerable  to  damage  from  computer  viruses  and
unauthorized access, and may fail. Our information technology and other internal infrastructure systems, including corporate firewalls, servers, data center
facilities,  lab  equipment,  and  internet  connection,  face  the  risk  of  breakdown  or  other  damage  or  interruption  from  service  interruptions,  system
malfunctions, natural disasters, terrorism, war, and telecommunication and electrical failures, as well as security breaches from inadvertent or intentional
actions by our employees, contractors, consultants, business partners, and/or other third parties, or from cyber-attacks by malicious third parties (including
the deployment of harmful malware, ransomware, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the
confidentiality,  integrity  and  availability  of  information),  each  of  which  could  compromise  our  system  infrastructure  or  lead  to  the  loss,  destruction,
alteration, disclosure, or dissemination of, or damage or unauthorized access to, our data or data that is processed or maintained on our behalf, or other
assets.

In addition, the loss or corruption of, or other damage to, clinical trial data from completed or future clinical trials could result in delays in our regulatory
approval efforts and could significantly increase our costs to recover or reproduce the data. Likewise, we will rely on third parties for the manufacture of our
current or future drug candidates and to conduct clinical trials, and similar events relating to their systems and operations could also have a material adverse
effect  on  our  business  and  lead  to  regulatory  agency  actions.  The  risk  of  a  security  breach  or  disruption,  particularly  through  cyber-attacks  or  cyber
intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity, and sophistication of
attempted attacks and intrusions from around the world have increased.

Sophisticated  cyber  attackers  (including  foreign  adversaries  engaged  in  industrial  espionage)  are  skilled  at  adapting  to  existing  security  technology  and
developing new methods of gaining access to organizations’ sensitive business data, which could result in the loss of proprietary information, including
trade secrets. We may be unable to anticipate all types of security threats and to implement preventive measures effective against all such security threats.
The  techniques  used  by  cyber  criminals  change  frequently,  may  not  be  recognized  until  launched,  and  can  originate  from  a  wide  variety  of  sources,
including outside groups such as external service providers, organized crime affiliates, terrorist organizations, or hostile foreign governments or agencies.

Any  security  breach  or  other  event  leading  to  the  loss  or  damage  to,  or  unauthorized  access,  use,  alteration,  disclosure,  or  dissemination  of,  personal
information,  including  personal  information  regarding  clinical  trial  subjects,  contractors,  directors,  or  employees,  our  intellectual  property,  proprietary
business  information,  or  other  confidential  or  proprietary  information,  could  directly  harm  our  reputation,  enable  competitors  to  compete  with  us  more
effectively, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, or
otherwise subject us to liability under laws and regulations that protect the privacy and security of personal information.

Each  of  the  foregoing  could  result  in  significant  legal  and  financial  exposure  and  reputational  damage  that  could  adversely  affect  our  business.
Notifications  and  follow-up  actions  related  to  a  security  incident  could  impact  our  reputation  or  cause  us  to  incur  substantial  costs,  including  legal  and
remediation costs, in connection with these measures and otherwise in connection with any actual or suspected security breach. Our efforts to detect and
prevent  security  incidents  and  otherwise  implement  our  internal  security  and  business  continuity  measures,  including  those  connected  with  any  actual,
potential, or anticipated attack, may cause us to incur significant cost, including those connected with the engagement of additional personnel (including
third-party experts and consultants), employment protection technologies, and employee training.

The costs related to significant security breaches or disruptions could be material and our insurance policies may not be adequate to compensate us for the
potential losses arising from any such disruption in, or failure or security breach of, our systems or third-party systems where information important to our
business operations or commercial development is stored or processed. In addition, such insurance may not be available to us in the future on economically
reasonable terms, or at all. Further, our insurance may not cover all claims made against us and could have high deductibles in any event, and defending a
suit, regardless of its merit, could be costly and divert management attention. Furthermore, if the information technology systems of our third-party vendors
and other contractors and consultants become subject to disruptions or security breaches, we may have insufficient recourse against such third parties and
we may

42

Table of Contents

have  to  expend  significant  resources  to  mitigate  the  impact  of  such  an  event,  and  to  develop  and  implement  protections  to  prevent  future  events  of  this
nature from occurring.

The  occurrence  of  such  a  cybersecurity  breach  could  result  in  interruptions  in  our  operations,  material  disruption  of  our  development  programs  or  our
business operations, and may cause us financial, legal, business, or reputational harm.

Fortress controls a voting majority of our common stock.

Risks Relating to Our Control by Fortress Biotech Inc.

Pursuant to the terms of the Class A common stock held by Fortress, Fortress is entitled to cast, for each share of Class A common stock held by Fortress,
the number of votes that is equal to one and one-tenth (1.1) times a fraction, the numerator of which is the sum of the shares of outstanding common stock
and the denominator of which is the number of shares of outstanding Class A common stock. Accordingly, as long as Fortress owns any shares of Class A
common stock, they will be able to control or significantly influence all matters requiring approval by our stockholders, including the election of directors
and  the  approval  of  mergers  or  other  business  combination  transactions.  The  interests  of  Fortress  may  not  always  coincide  with  the  interests  of  other
stockholders,  and  Fortress  may  take  actions  that  advance  its  own  interests  and  are  contrary  to  the  desires  of  our  other  stockholders.  Moreover,  this
concentration  of  voting  power  may  delay,  prevent  or  deter  a  change  in  control  of  us  even  when  such  a  change  may  be  in  the  best  interests  of  all
stockholders, could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of Checkpoint or our assets,
and might affect the prevailing market price of our common stock.

Fortress  has  the  right  to  receive  a  significant  grant  of  shares  of  our  common  stock  annually  which  will  result  in  the  dilution  of  your  holdings  of
common stock upon each grant, which could reduce their value.

Under the terms of the Founders Agreement, which became effective as of March 17, 2015 and was amended and restated on July 11, 2016, Fortress has
the right to receive an annual grant of shares of our common stock equal to 2.5% of the fully-diluted outstanding equity at the time of issuance on January 1
of each year. This annual issuance of shares to Fortress will dilute your holdings in our common stock and, if the value of Checkpoint has not grown over
the prior year, would result in a reduction in the value of your shares.

We might have received better terms from unaffiliated third parties than the terms we receive in our agreements with Fortress.

The agreements we entered into with Fortress in connection with the separation include a Management Services Agreement and the Founders Agreement.
While  we  believe  the  terms  of  these  agreements  are  reasonable,  they  might  not  reflect  terms  that  would  have  resulted  from  arm’s-length  negotiations
between unaffiliated third parties. The terms of the agreements relate to, among other things, payment of a royalty on product sales and the provision of
employment  and  transition  services.  We  might  have  received  better  terms  from  third  parties  because,  among  other  things,  third  parties  might  have
competed with each other to win our business.

Risks Related to Conflicts of Interest

The  Chairman  of  our  Board  of  Directors  is  also  the  Executive  Chairman,  President  and  Chief  Executive  Officer  of  TGTX,  with  whom  we  have  a
collaboration agreement and a sublicense agreement. As a result, during the term of these agreements, certain conflicts of interest may arise which will
require the attention of our officers and independent directors who are unaffiliated with TGTX.

In  connection  with  our  license  agreement  with  Dana-Farber  and  Adimab,  we  entered  into  a  collaboration  agreement  with  TGTX  to  develop  and
commercialize the anti-PD-L1 and anti-GITR antibody research programs, including cosibelimab in the field of hematological malignancies. Michael S.
Weiss,  our  Chairman  of  the  Board  of  Directors,  is  also  the  Executive  Chairman,  President  and  Chief  Executive  Officer  of  TGTX.  As  such,  as  the
collaboration agreement proceeds, certain conflicts of interest may arise between us and TGTX. Those conflicts will have to be resolved by our officers and
directors who are unaffiliated with TGTX, and also by officers and directors of TGTX who are unaffiliated with us. This may lead to less than desirable
complications and costs to both companies, which could harm our results of operations.

In  connection  with  our  license  agreement  with  Jubilant,  we  entered  into  a  sublicense  agreement  with  TGTX  to  develop  and  commercialize  the  Jubilant
family of patents covering compounds that inhibit BET proteins such as BRD4, including CK-103, in the

43

Table of Contents

field of hematological malignancies. As such, as the sublicense agreement proceeds, certain conflicts of interest may arise between us and TGTX. Those
conflicts  will  have  to  be  resolved  by  our  officers  and  directors  who  are  unaffiliated  with  TGTX,  and  also  by  officers  and  directors  of  TGTX  who  are
unaffiliated with us. This may lead to less than desirable complications and costs to both companies, which could harm our results of operations.

The dual roles of our directors who also serve in similar roles with Fortress could create a conflict of interest and will require careful monitoring by
our independent directors.

We share some directors with Fortress which could create conflicts of interest between the two companies in the future. While we believe that the Founders
Agreement and the Management Services Agreement were negotiated by independent parties on both sides on arm’s length terms, and the fiduciary duties
of both parties were thereby satisfied, in the future situations may arise under the operation of both agreements that may create a conflict of interest. We will
have to be diligent to ensure that any such situation is resolved by independent parties. In particular, under the Management Services Agreement, Fortress
and its affiliates are free to pursue opportunities which could potentially be of interest to Checkpoint, and they are not required to notify Checkpoint prior to
pursuing  the  opportunity. Any  such  conflict  of  interest  or  pursuit  by  Fortress  of  a  corporate  opportunity  independent  of  Checkpoint  could  expose  us  to
claims by our investors and creditors and could harm our results of operations.

General Risks

Major public health issues, and specifically the pandemic caused by the spread of COVID-19, could have an adverse impact on our financial condition
and results of operations and other aspects of our business.

In December 2019, a novel strain of coronavirus, COVID-19, was first detected in Wuhan, China, and has since spread around the world. On March 11,
2020, the World Health Organization declared that the rapidly spreading COVID-19 outbreak had evolved into a pandemic. In response to the pandemic,
many  governments  around  the  world  are  implementing  a  variety  of  measures  to  reduce  the  spread  of  COVID-19,  including  travel  restrictions  and  bans,
instructions to residents to practice social distancing, quarantine advisories, shelter-in-place orders and required closures of non-essential businesses.

The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, and created significant volatility and disruption of
financial markets. Although COVID-19 has not had a material adverse effect on our business to date, no assurance can be given that it will not in the future
if the situation persists or worsens. The extent to which the coronavirus impacts our business and operating results will depend on future developments that
are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning the coronavirus and the actions to contain
the coronavirus or treat its impact, among others.

Should the coronavirus continue to spread, our business operations could be delayed or interrupted. For instance, our clinical trials may be affected by the
pandemic.  Site  initiation,  participant  recruitment  and  enrollment,  participant  dosing,  distribution  of  clinical  trial  materials,  study  monitoring  and  data
analysis may be paused or delayed due to changes in hospital or university policies, federal, state or local regulations, prioritization of hospital resources
toward pandemic efforts, or other reasons related to the pandemic. If the coronavirus continues to spread, some participants and clinical investigators may
not  be  able  to  comply  with  clinical  trial  protocols.  For  example,  quarantines  or  other  travel  limitations  (whether  voluntary  or  required)  may  impede
participant movement, affect sponsor access to study sites, or interrupt healthcare services, and we may be unable to conduct our clinical trials. Infections
and deaths related to the pandemic may disrupt the United States’ and other countries’ healthcare and healthcare regulatory systems. Such disruptions could
divert healthcare resources away from, or materially delay FDA or other regulatory review and/or approval with respect to, our clinical trials. It is unknown
how  long  these  disruptions  could  continue,  were  they  to  occur. Any  elongation  or  de-prioritization  of  our  clinical  trials  or  delay  in  regulatory  review
resulting from such disruptions could materially affect the development and study of our product candidates.

We currently rely on third parties, such as contract laboratories, contract research organizations, medical institutions and clinical investigators to conduct
these  studies  and  clinical  trials.  If  these  third  parties  themselves  are  adversely  impacted  by  restrictions  resulting  from  the  coronavirus  outbreak,  we  will
likely  experience  delays  and/or  realize  additional  costs.  We  also  rely  on  third  parties  for  the  manufacture  of  our  product  candidates  for  preclinical  and
clinical testing. Disruptions to the global supply chain could impact our or our third-party manufacturers’ ability to obtain raw materials or other products
necessary  to  manufacture  and  distribute  our  product  candidates. As  a  result,  our  efforts  to  obtain  regulatory  approvals  for,  and  to  commercialize,  our
product candidates may be delayed or disrupted.

Table of Contents

The  Company’s  employees  have  been  and  are  currently  being  affected  by  the  COVID-19  pandemic.  Our  office  and  management  personnel  are  mostly
working remotely, and the Company may need to enact further precautionary measures to help minimize the risk of our employees being exposed to the
coronavirus.  If  these  conditions  worsen,  or  last  for  an  extended  period  of  time,  the  Company’s  ability  to  manage  its  business  may  be  impaired,  and
operational risks, cybersecurity risks and other risks the Company faced even prior to the pandemic may be elevated.

The potential economic impact brought by and the duration of the pandemic may be difficult to assess or predict, however it has already caused, and is
likely  to  result  in  further,  significant  disruption  of  global  financial  markets,  which  may  reduce  our  ability  to  access  capital  either  at  all  or  on  favorable
terms.  In  addition,  a  recession,  depression  or  other  sustained  adverse  market  event  resulting  from  the  spread  of  the  coronavirus  could  materially  and
adversely affect our business and the value of our common stock.

The  ultimate  impact  of  the  current  pandemic,  or  any  other  health  epidemic,  is  highly  uncertain  and  will  depend  on  future  developments  that  cannot  be
predicted with confidence, such as the duration of the outbreak, the severity of COVID-19, and the effectiveness of actions to contain and treat for COVID-
19. Although, as of the date of this Annual Report on Form 10-K, we do not expect any material impact on our long-term activity, we do not yet know the
full extent of potential delays or impacts on our business, our clinical trials, our research programs, healthcare systems or the global economy as a whole,
which could have a material adverse effect on our business, financial condition and results of operations and cash flows.

We may not be able to manage our business effectively if we are unable to attract and retain key personnel.

We  may  not  be  able  to  attract  and/or  retain  qualified  management  and  commercial,  scientific  and  clinical  personnel  in  the  future  due  to  the  intense
competition for qualified personnel among biotechnology, pharmaceutical and other businesses. If we are not able to attract and retain necessary personnel
to accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our
ability to raise additional capital and our ability to implement our business strategy.

Our employees or third-party contractors may engage in misconduct or other improper activities, including noncompliance with regulatory standards
and requirements, which could have a material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees or third-party contractors could include intentional failures to
comply with FDA regulations, provide accurate information to the FDA, comply with manufacturing standards we have established, comply with federal
and  state  health-care  fraud  and  abuse  laws  and  regulations,  report  financial  information  or  data  accurately  or  disclose  unauthorized  activities  to  us.  In
particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud,
kickbacks,  bribery,  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.  Employee  or  third-party  contractors
misconduct  could  also  involve  the  improper  use  of  information  obtained  in  the  course  of  clinical  trials,  which  could  result  in  regulatory  sanctions  and
serious harm to our reputation, as well as civil and criminal liability. The precautions we take to detect and prevent this activity may not be effective in
controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  us  from  governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a
failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or
asserting our rights, those actions could have a significant impact on our business and results of operations, including the imposition of significant fines
and/or other civil and/or criminal sanctions.

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

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use,
storage,  treatment  and  disposal  of  hazardous  materials  and  wastes.  Our  operations  involve  the  use  of  hazardous  and  flammable  materials,  including
chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these
materials  and  wastes.  We  cannot  eliminate  the  risk  of  contamination  or  injury  from  these  materials. Although  we  believe  that  the  safety  procedures  for
handling and disposing of these materials comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of accidental
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 any 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.

45

Table of Contents

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  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 research, development or production efforts. Our failure to comply with these laws and regulations also may
result in substantial fines, penalties or other sanctions.

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

Despite  the  implementation  of  security  measures,  our  internal  computer  systems  are  vulnerable  to  damage  from  computer  viruses,  unauthorized  access,
natural disasters, terrorism, war and telecommunication and electrical failures. Any system failure, accident or security breach that causes interruptions in
our operations could result in a material disruption of our drug development programs. For example, the loss of clinical trial data from completed clinical
trials for one or more of our product conducts could result in delays in our regulatory 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 or damage to our data or applications, or inappropriate disclosure of
confidential or proprietary information, we may incur liability and the further development of one or more of our product candidates may be delayed.

The market price and trading volume of our common stock has been volatile. Our stock may continue to be subject to substantial price and volume
fluctuations due to a number of factors, many of which are beyond our control and may prevent our stockholders from reselling our common stock at a
profit.

The market prices for securities of biotechnology and pharmaceutical companies have historically been highly volatile, and the market has from time to
time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies.

The  market  price  and  trading  volume  of  our  common  stock  has  been  highly  volatile  and  is  likely  to  continue  to  be  highly  volatile  and  may  fluctuate
substantially due to many factors, including:

●
●

announcements relating to the clinical development of our product candidates;
announcements  concerning  the  progress  of  our  efforts  to  obtain  regulatory  approval  for  and  commercialize  our  product  candidates  or  any  future
product candidate, including any requests we receive from the FDA, or comparable regulatory authorities outside the United States, for additional
studies or data that result in delays or additional costs in obtaining regulatory approval or launching these product candidates, if approved;
the depth and liquidity of the market for our common stock;
investor perceptions about us and our business;

●
●
● market conditions in the pharmaceutical and biotechnology sectors or the economy as a whole, which may be impacted by economic or other crises

or external factors, including the effects of the COVID-19 pandemic on the global economy;
price and volume fluctuations in the overall stock market;
the failure of one or more of our product candidates or any future product candidate, if approved, to achieve commercial success;
announcements of the introduction of new products by us or our competitors;
developments concerning product development results or intellectual property rights of others;
litigation or public concern about the safety of our potential products;
actual fluctuations in our quarterly operating results, and concerns by investors that such fluctuations may occur in the future;
deviations in our operating results from the estimates of securities analysts or other analyst comments;
additions or departures of key personnel;
health  care  reform  legislation,  including  measures  directed  at  controlling  the  pricing  of  pharmaceutical  products,  and  third-party  coverage  and
reimbursement policies;
developments concerning current or future strategic collaborations; and
discussion of us or our stock price by the financial and scientific press and in online investor communities.

We may become involved in securities class action litigation that could divert management’s attention and harm our business.

The market price and trading volume of our common stock has been highly volatile and is likely to continue to be highly volatile. In addition, the stock
markets  have  from  time  to  time  experienced  significant  price  and  volume  fluctuations  that  have  affected  the  market  prices  for  the  common  stock  of
biotechnology and pharmaceutical companies. These broad market fluctuations may cause the market price of our stock to decline. In the past, securities
class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for
us because biotechnology and biopharmaceutical companies have experienced significant stock price volatility in recent years. We may become involved in
this  type  of  litigation  in  the  future.  Litigation  often  is  expensive  and  diverts  management’s  attention  and  resources,  which  could  adversely  affect  our
business.

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

Forward-Looking Statements

Statements  in  the  following  discussion  and  throughout  this  report  that  are  not  historical  in  nature  are  “forward-looking  statements.”  You  can  identify
forward-looking statements by the use of words such as “expect,” “anticipate,” “estimate,” “may,” “will,” “should,” “intend,” “believe,” and similar
expressions. Although we believe the expectations reflected in these forward-looking statements are reasonable, such statements are inherently subject to
risk and we can give no assurances that our expectations will prove to be correct. Actual results could differ from those described in this report because of
numerous  factors,  many  of  which  are  beyond  our  control.  These  factors  include,  without  limitation,  those  described  under  Item  1A  “Risk  Factors.”  We
undertake  no  obligation  to  update  these  forward-looking  statements  to  reflect  events  or  circumstances  after  the  date  of  this  report  or  to  reflect  actual
outcomes. Please see “Forward-Looking Statements” at the beginning of this Form 10-K.

The following discussion of our financial condition and results of operations should be read in conjunction with our financial statements and the related
notes  thereto  and  other  financial  information  appearing  elsewhere  in  this  Form  10-K.  We  undertake  no  obligation  to  update  any  forward-looking
statements in the discussion of our financial condition and results of operations to reflect events or circumstances after the date of this report or to reflect
actual outcomes.

Overview

We  are  a  clinical-stage  immunotherapy  and  targeted  oncology  company  focused  on  the  acquisition,  development  and  commercialization  of  novel
treatments for patients with solid tumor cancers. We are evaluating our lead antibody product candidate, cosibelimab, an anti-PD-L1 antibody licensed from
the  Dana-Farber,  in  an  ongoing  global,  open-label,  multicohort  Phase  1  clinical  trial  in  checkpoint  therapy-naïve  patients  with  selected  recurrent  or
metastatic  cancers,  including  ongoing  cohorts  in  locally  advanced  and  metastatic  cutaneous  squamous  cell  carcinoma  intended  to  support  one  or  more
applications  for  marketing  approval.  In  addition,  we  are  evaluating  our  lead  small-molecule,  targeted  anti-cancer  agent,  olafertinib,  a  third-generation
EGFR inhibitor, as a potential new treatment for patients with EGFR mutation-positive NSCLC.

In January 2022, we announced topline results from a cohort of the registration-enabling Phase 1 clinical trial of cosibelimab administered as a fixed dose
of 800 mg every two weeks in patients with metastatic CSCC. The cohort met its primary endpoint, with cosibelimab demonstrating a confirmed ORR of
47.4% (95% CI: 36.0, 59.1) based on independent central review of 78 patients enrolled in the metastatic CSCC cohort using RECIST 1.1.

In December 2021, we announced the initiation of our CONTERNO study, a global, open-label, multi-center, randomized Phase 3 trial of cosibelimab in
combination with pemetrexed and platinum chemotherapy for the first-line treatment of patients with NSCLC. The primary endpoint for the CONTERNO
Phase 3 trial is OS, and key secondary endpoints include PFS, ORR and safety.

We have also entered into various collaboration agreements with TGTX, a related party, to develop and commercialize certain assets in connection with our
licenses in the field of hematological malignancies, while we retain the right to develop and commercialize these assets in solid tumors.

To date, we have not received approval for the sale of any product candidate in any market and, therefore, have not generated any product sales from any
product  candidates.  In  addition,  we  have  incurred  substantial  operating  losses  since  our  inception,  and  expect  to  continue  to  incur  significant  operating
losses for the foreseeable future and may never become profitable. As of December 31, 2021, we have an accumulated deficit of $199.9 million.

We are a majority-controlled subsidiary of Fortress.

Checkpoint Therapeutics, Inc. was incorporated in Delaware on November 10, 2014 and commenced principal operations in March 2015. Our executive
offices  are  located  at  95  Sawyer  Road,  Suite  110,  Waltham,  MA  02453.  Our  telephone  number  is  (781)  652-4500  and  our  email  address  is

Critical Accounting Policies and Use of Estimates

Our  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  are  based  on  our  financial  statements,  which  have  been  prepared  in
accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of these financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities
in  our  financial  statements.  On  an  ongoing  basis,  we  evaluate  our  estimates  and  judgments,  including,  but  not  limited  to,  those  related  to  research  and
development expenses, accrued research and development expenses and stock-based compensation. We base our estimates on historical experience, known
trends  and  events  and  various  other  factors  that  are  believed  to  be  reasonable  under  the  circumstances,  the  results  of  which  form  the  basis  for  making
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates
under different assumptions or conditions.

Our  significant  accounting  policies  are  described  in  the  notes  to  our  financial  statements  appearing  elsewhere  in  this  Form  10-K.  We  believe  that  the
accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas
involving management's judgments and estimates.

Research and Development

Research and development costs are expensed as incurred. Advance payments for goods and services that will be used in future research and development
activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. Upfront and
milestone payments due to third parties that perform research and development services on the Company's behalf will be expensed as services are rendered
or when the milestone is achieved.

Research and development costs primarily consist of personnel related expenses, including salaries, benefits, travel, and other related expenses, stock-based
compensation, payments made to third parties for license and milestone costs related to in-licensed products and technology, payments made to third party
contract research organizations for preclinical and clinical studies, investigative sites for clinical trials, consultants, the cost of acquiring and manufacturing
clinical trial materials, and costs associated with regulatory filings, laboratory costs and other supplies.

In accordance with ASC 730 10 25 1, Research and Development, costs incurred in obtaining technology licenses are charged to research and development
expense  if  the  technology  licensed  has  not  reached  commercial  feasibility  and  has  no  alternative  future  use.  In  each  case,  we  evaluate  if  the  license
agreement  results  in  the  acquisition  of  an  asset  or  a  business.  Such  licenses  purchased  by  the  Company  require  substantial  completion  of  research  and
development, regulatory and marketing approval efforts in order to reach commercial feasibility and has no alternative future use. Accordingly, the total
purchase price for the licenses acquired during the period is reflected as research and development on the Consolidated Statements of Operations.

Accrued Research and Development Expense

We  record  accruals  for  estimated  costs  of  research,  preclinical,  clinical  and  manufacturing  development  within  accrued  expenses  which  are  significant
components of research and development expenses. A substantial portion of our ongoing research and development activities is conducted by third-party
service  providers  such  as  contract  research  organizations  in  connection  with  our  clinical  studies,  contract  manufacturing  organizations,  trial  sites  in
connection with our clinical studies and vendors associated with licenses/milestones. We accrue the costs incurred under agreements with these third parties
based  on  estimates  of  actual  work  completed  in  accordance  with  the  respective  agreements.  We  determine  the  estimated  costs  through  the  reviewing  of
open contracts, communicating with our personnel to identify services that have been performed 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 cost. The majority of our service
providers invoice us monthly for services performed or when contractual milestones are met.. Payments made to third parties under these arrangements in
advance of the performance of the related services are recorded as prepaid expenses until the services are rendered.

If  the  actual  timing  of  the  performance  of  services  or  the  level  of  effort  varies  from  the  estimate,  we  adjust  accrued  expenses  or  prepaid  expenses
accordingly, which impact research and development expenses. Although we do not expect our estimates to be materially different from amounts actually
incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may
result in reporting amounts that are too high or too low in any particular period.

50

Table of Contents

Stock-Based Compensation

The Company expenses stock-based compensation to employees and non-employees over the requisite service period based on the estimated grant-date fair
value of the awards and forfeitures, which are recorded upon occurrence. The Company estimates the fair value of stock option grants using the Black-
Scholes option pricing model. The assumptions used in calculating the fair value of stock-based awards represent management's best estimates and involve
inherent uncertainties and the application of management's judgment.

We will continue to use judgment in evaluating the expected volatility, expected terms and interest rates utilized for our stock-based compensation expense
calculations  on  a  prospective  basis.  The  assumptions  underlying  these  valuations  represent  our  management's  best  estimate,  which  involve  inherent
uncertainties  and  the  application  of  management  judgment.  As  a  result,  if  factors  or  expected  outcomes  change  and  we  use  significantly  different
assumptions  or  estimates,  our  stock-based  compensation  expense  could  be  materially  different.  We  expect  to  continue  to  grant  options  and  other  stock-
based awards in the future, and to the extent that we do, our stock-based compensation expense recognized in future periods will likely increase.

Results of Operations

In  this  section,  we  discuss  the  results  of  our  operations  for  the  year  ended  December  31,  2021  compared  to  the  year  ended  December  31,  2020.  For  a
discussion of the year ended December 31, 2020 compared to the year ended December 31, 2019, please refer to Part II, Item 7, “Management’s Discussion
and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2020.

Comparison of the Years Ended December 31, 2021 and 2020

Revenue

For the year ended December 31, 2021, revenue was approximately $0.3 million compared to approximately $1.1 million for the year ended December 31,
2020, a decrease of approximately $0.8 million. Revenue for the current period primarily consisted of $0.2 million from TGTX related to the collaboration
agreement.  Revenue  for  the  year  ended  December  31,  2020  primarily  consisted  of  $1.0  million  from  TGTX  related  to  the  collaboration  agreement,
including a milestone of $925,000 upon the 12th patient dosed in a phase 1 clinical trial for cosibelimab during March 2020.

Research and Development Expenses

Research and development expenses primarily consist of personnel related expenses, including salaries, benefits, travel, and other related expenses, stock-
based compensation, payments made to third parties for license and milestone costs related to in-licensed products and technology, payments made to third
party  CROs  for  preclinical  and  clinical  studies,  investigative  sites  for  clinical  trials,  consultants,  the  cost  of  acquiring  and  manufacturing  clinical  trial
materials, costs associated with regulatory filings and patents, laboratory costs and other supplies.

For the year ended December 31, 2021, research and development expenses were approximately $48.5 million, compared to approximately $16.4 million
for the year ended December 31, 2020, an increase of $32.1 million. The current period research and development expenses primarily consisted of $17.0
million related to the manufacturing costs of our product candidates, $14.3 million related to clinical costs for our product candidates, $6.6 million related
to the non-cash annual equity fee in connection with the Founders’ Agreement, $6.4 million related to a non-refundable milestone payment upon the first
patient dosed in a Phase 3 clinical study of cosibelimab, $1.5 million related to salary expenses and $0.7 million related to stock compensation expense. For
the  year  ended  December  31,  2020,  research  and  development  expenses  primarily  consisted  of  $8.0  million  related  to  clinical  costs  for  our  product
candidates,  $1.7  million  related  to  manufacturing  and  related  costs  of  our  product  candidates,  $4.6  million  related  to  the  non-cash  annual  equity  fee  in
connection with the Founders’ Agreement, $0.6 million related to salary expenses and $0.6 million related to stock compensation expense.

We anticipate research and development expenses in 2022 to increase modestly as compared to 2021.

General and Administrative Expenses

General  and  administrative  expenses  consist  primarily  of  salaries  and  related  expenses,  including  stock-based  compensation,  for  executives  and  other
administrative personnel, recruitment expenses, professional fees and other corporate expenses, including investor relations, legal activities, and facilities-
related expenses.

For the year ended December 31, 2021, general and administrative expenses were approximately $8.5 million, compared to approximately $7.9 million for
the  year  ended  December  31,  2020,  an  increase  of  $0.6  million.  The  current  period  general  and  administrative  expenses  primarily  consisted  of  stock
compensation expense of $2.5 million, $1.4 million related to salary expenses, $1.0 million related to our issuance of shares to Fortress pursuant to the
Founders Agreement in connection with the sale of shares of our common stock, $1.0 million related to legal and accounting fees and $0.4 million related
to  investor  relation  fees.  The  prior  period  general  and  administrative  expenses  primarily  consisted  of  stock  compensation  expense  of  $2.2  million,  $1.2
million related to salary expenses, $0.9 million related to legal and accounting fees, $0.9 million related to our issuance of shares to Fortress pursuant to the
Founders Agreement in connection with the sale of shares of our common stock under an At-the-Market Issuance Sales Agreement (the “ATM”) and $0.9
million related to investor relation fees.

We anticipate general and administrative expenses in 2022 to modestly increase as compared to 2021.

Liquidity and Capital Resources

We have incurred substantial operating losses since our inception and expect to continue to incur significant operating losses for the foreseeable future and
may never become profitable. As of December 31, 2021, we had an accumulated deficit of $199.9 million.

During the year ended December 31, 2021, we sold a total of 11,899,983 shares of common stock under the ATM for aggregate total gross proceeds of
approximately  $41.3  million  at  an  average  selling  price  of  $3.47  per  share,  resulting  in  net  proceeds  of  approximately  $40.3  million  after  deducting
commissions and other transaction costs.

In September 2020, we completed an underwritten public offering in which we sold 7,321,429 shares of our common stock at a price of $2.80 per share for
gross proceeds of approximately $20.5 million. Total net proceeds from the offering were approximately $18.9 million, net of underwriting discounts and
offering expenses of approximately $1.6 million. The shares were sold under a Registration Statement (No. 333-221493) on Form S-3 (the “2017 S-3”),
filed with the SEC.

During  the  year  ended  December  31,  2020,  we  sold  a  total  of  5,104,234  shares  of  common  stock  under  the ATM  for  aggregate  total  gross  proceeds  of
approximately  $12.8  million  at  an  average  selling  price  of  $2.50  per  share,  resulting  in  net  proceeds  of  approximately  $12.4  million  after  deducting
commissions and other transaction costs.

Our major sources of cash have been proceeds from the sale of equity securities. We expect to use these proceeds primarily for general corporate purposes,
which may include financing our growth, developing new or existing product candidates, and funding capital expenditures, acquisitions and investments.
We currently believe that our cash and cash equivalents balances are sufficient to fund our anticipated operating cash requirements for at least one year
from the date of issuance of this Annual Report on Form 10-K.

We will be required to expend significant funds in order to advance the development of our product candidates. Our estimate as to how long we expect our
existing cash to be able to continue to fund our operations is based on assumptions that may prove to be wrong, and we could use our available capital
resources sooner than we currently expect. Further, changing circumstances, some of which may be beyond our control, could cause us to consume capital
faster  than  we  currently  anticipate,  and  we  may  need  to  seek  additional  funds  sooner  than  planned. Accordingly,  we  will  be  required  to  obtain  further
funding through equity offerings, debt financings, collaborations and licensing arrangements or other sources. Further financing may not be available to us
on acceptable terms, or at all. Our failure to raise capital as and when needed would have a negative impact on our financial condition and our ability to
pursue our business strategy and we may be forced to curtail or cease operations.

In addition to the foregoing, based on the Company’s current assessment, the Company does not expect any material impact on its long-term development
timeline  and  its  liquidity  due  to  the  worldwide  spread  of  COVID-19.  However,  the  Company  is  continuing  to  assess  the  effect  on  its  operations  by
monitoring the spread of COVID-19, as well as the effect of the COVID-19 pandemic on the Company’s clients, vendors, and business partners, and the
actions implemented to combat the virus throughout the world.

Off-Balance Sheet Arrangements

We  are  not  party  to  any  off-balance  sheet  transactions.  We  have  no  guarantees  or  obligations  other  than  those  which  arise  out  of  normal  business
operations.

Cash Flows for the Years Ended December 31, 2021 and 2020

Operating Activities

Net cash used in operating activities was $26.3 million for the year ended December 31, 2021, compared to $16.6 million for the year ended December 31,
2020. The increase in net cash used in operating activities was due primarily to an increase in manufacturing of cosibelimab and clinical trial expenses in the
current period.

Investing Activities

There were no investing activities for the years ended December 31, 2021 and 2020.

Financing Activities

Net  cash  provided  by  financing  activities  was  $40.3  million  for  the  year  ended  December  31,  2021,  which  related  to  net  proceeds  from  the  issuance  of
common stock as part of our ATM offerings. Net cash provided by financing activities was $31.2 million for the year ended December 31, 2020, which
related to net proceeds of $18.9 million from the issuance of common stock as part of our underwritten public offering in September 2020 and net proceeds
of $12.4 million from the issuance of common stock as part of our ATM offerings.

Item 7A.     Quantitative and Qualitative Disclosures About Market Risks

Market risk represents the risk of loss that may result from the change in value of financial instruments due to fluctuations in their market price. Market risk
is inherent in all financial instruments. Market risk may be exacerbated in times of trading illiquidity when market participants refrain from transacting in
normal quantities and/or at normal bid-offer spreads. The primary quantifiable market risk associated with our financial instruments is sensitivity to changes
in  interest  rates.  Interest  rate  risk  represents  the  potential  loss  from  adverse  changes  in  market  interest  rates.  The  primary  objective  of  our  investment
activities is to preserve principal while maximizing our income from investments and minimizing our market risk. As of December 31, 2021, our portfolio
of financial instruments consists of cash equivalents, including money market funds. Due to the short-term nature of these financial instruments, we believe
there is no material exposure to interest rate risk, and/or credit risk, arising from our portfolio of financial instruments.

Our assets and liabilities are denominated in U.S. dollars. Consequently, we have not  considered  it  necessary  to  use  foreign  currency  contracts  or  other
derivative  instruments  to  manage  changes  in  currency  rates.  We  do  not  now,  nor  do  we  plan  to,  use  derivative  financial  instruments  for  speculative  or
trading purposes. However, these circumstances might change.

Item 9A.     Controls and Procedures.

Evaluation of Disclosure Controls and Procedures.

As  of  December  31,  2021,  management  carried  out,  under  the  supervision  and  with  the  participation  of  our  principal  executive  officer  and  principal
financial officer, an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and
15d-15(e) under the Exchange Act). Our disclosure controls and procedures are designed to provide reasonable assurance that information we are required
to disclose in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified
in applicable rules and forms. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of December 31,
2021, our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) or Rule
15d-15(f) under the Exchange Act). Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In
making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, known as
COSO,  in  Internal  Control-Integrated  Framework  (2013).  Our  management  has  concluded  that,  as  of  December  31,  2021,  our  internal  control  over
financial reporting was effective based on these criteria.

Changes in Internal Control Over Financial Reporting.

There were no changes in our internal control over financial reporting during the most recent fiscal quarter that have materially affected, or are reasonably
likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls.

Our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or
our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide
only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that
there  are  resource  constraints,  and  the  benefits  of  controls  must  be  considered  relative  to  their  costs.  Because  of  the  inherent  limitations  in  all  control
systems,  no  evaluation  of  controls  can  provide  absolute  assurance  that  all  control  issues  and  instances  of  fraud,  if  any,  within  our  company  have  been
detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Shareholders and Board of Directors
Checkpoint Therapeutics, Inc.
Waltham, MA

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Checkpoint  Therapeutics,  Inc.  (the  “Company”)  as  of  December  31,  2021  and  2020,  the  related
statements  of  operations,  stockholders’  equity,  and  cash  flows  for  the  years  then  ended,  and  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 at December 31, 2021
and 2020, and the results of its operations and its cash flows for the years then ended, 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 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.

/s/ BDO USA, LLP
We have served as the Company’s auditor since 2016.

Note 1 - Organization and Description of Business Operations

CHECKPOINT THERAPEUTICS, INC.
Notes to Financial Statements

Checkpoint  Therapeutics,  Inc.  (the  “Company”  or  “Checkpoint”)  was  incorporated  in  Delaware  on  November  10,  2014.  Checkpoint  is  a  clinical-stage
immunotherapy and targeted oncology company focused on the acquisition, development and commercialization of novel treatments for patients with solid
tumor  cancers.  The  Company  may  acquire  rights  to  these  technologies  by  licensing  the  rights  or  otherwise  acquiring  an  ownership  interest  in  the
technologies, funding their research and development and eventually either out-licensing or bringing the technologies to market. The Company may also
enter into collaboration agreements with third and related parties including sponsored research agreements to develop these technologies for liquid tumors
while retaining the rights in solid tumors.

The Company is a majority-controlled subsidiary of Fortress Biotech, Inc. (“Fortress”).

The Company’s common stock is listed on the NASDAQ Capital Market and trades under the symbol “CKPT.”

Liquidity and Capital Resources

The Company has incurred substantial operating losses since its inception and expects to continue to incur significant operating losses for the foreseeable
future and may never become profitable. As of December 31, 2021, the Company had an accumulated deficit of $199.9 million.

During  the  year  ended  December  31,  2021,  the  Company  sold  a  total  of 11,899,983  shares  of  common  stock  under  the ATM  for  aggregate  total  gross
proceeds  of  approximately  $41.3  million  at  an  average  selling  price  of  $3.47  per  share,  resulting  in  net  proceeds  of  approximately  $40.3  million  after
deducting commissions and other transaction costs.

The Company expects to continue to use the proceeds from previous financing transactions primarily for general corporate purposes, which may include
financing  the  Company’s  growth,  developing  new  or  existing  product  candidates,  and  funding  capital  expenditures,  acquisitions  and  investments.  The
Company currently anticipates that its cash and cash equivalents balances are sufficient to fund its anticipated operating cash requirements for at least one
year from the date of issuance of this Annual Report on Form 10-K.

The Company will be required to expend significant funds in order to advance the development of its product candidates. The Company’s estimate as to
how long it expects its existing cash to be able to continue to fund its operations is based on assumptions that may prove to be wrong, and it could use its
available capital resources sooner than it currently expects. Further, changing circumstances, some of which may be beyond its control, could cause the
Company to consume capital faster than it currently anticipates, and it may need to seek additional funds sooner than planned. Accordingly, the Company
will  be  required  to  obtain  further  funding  through  equity  offerings,  debt  financings,  collaborations  and  licensing  arrangements  or  other  sources.  Further
financing may not be available to it on acceptable terms, or at all. The Company’s failure to raise capital as and when needed would have a negative impact
on its financial condition and its ability to pursue its business strategy and may be forced to curtail or cease operations.

In addition to the foregoing, based on the Company’s current assessment, the Company does not expect any material impact on its long-term development
timeline and its liquidity due to the worldwide spread of the coronavirus (“COVID-19”). However, the Company is continuing to assess the effect on its
operations  by  monitoring  the  spread  of  COVID-19,  as  well  as  the  effect  of  the  COVID-19  pandemic  on  the  Company’s  clients,  vendors,  and  business
partners, and the actions implemented to combat the virus throughout the world.

Note 2 - Significant Accounting Policies

Basis of Presentation

The  Company’s  financial  statements  have  been  prepared  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of America
(“GAAP”) and include all adjustments necessary for the fair presentation of the Company’s financial position for the periods presented. The Company has
no subsidiaries.

F-7

Table of Contents

Segments

CHECKPOINT THERAPEUTICS, INC.
Notes to Financial Statements

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating
decision  maker,  or  decision-making  group,  in  deciding  how  to  allocate  resources  and  in  assessing  performance.  The  Company  views  its  operations  and
manages its business in one operating and reporting segment.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts
of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during
the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

Other Receivables - Related Party

Other receivables includes amounts due to the Company from TG Therapeutics, Inc. (“TGTX”), a related party, and are recorded at the invoiced amount.

Research and Development Costs

Research and development costs are expensed as incurred. Advance payments for goods and services that will be used in future research and development
activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. Upfront and
milestone payments due to third parties that perform research and development services on the Company’s behalf will be expensed as services are rendered
or when the milestone is achieved.

Research and development costs primarily consist of personnel related expenses, including salaries, benefits, travel, and other related expenses, stock-based
compensation, payments made to third parties for license and milestone costs related to in-licensed products and technology, payments made to third party
contract research organizations for preclinical and clinical studies, investigative sites for clinical trials, consultants, the cost of acquiring and manufacturing
clinical trial materials, costs associated with regulatory filings, laboratory costs and other supplies.

In accordance with Accounting Standards Codification (“ASC”) 730-10-25-1, Research and Development, costs incurred in obtaining technology licenses
are charged to research and development expense if the technology licensed has not reached commercial feasibility and has no alternative future use. Such
licenses  purchased  by  the  Company  require  substantial  completion  of  research  and  development,  regulatory  and  marketing  approval  efforts  in  order  to
reach commercial feasibility and have no alternative future use.

Annual Equity Fee

Under the Founder’s Agreement with Checkpoint dated March 17, 2015 and amended in July 2016 and October 2017 (the “Founders Agreement”), Fortress
is  entitled  to  an  annual  equity  fee  on  January  1  of  each  year  equal  to 2.5%  of  fully  diluted  outstanding  equity,  payable  in  Checkpoint  common  shares
(“Annual  Equity  Fee”).  The Annual  Equity  Fee  was  part  of  the  consideration  payable  for  formation  of  the  Company,  identification  of  certain  assets,
including the license contributed to Checkpoint by Fortress (see Note 4).

The  Company  records  the  Annual  Equity  Fee  in  connection  with  the  Founders  Agreement  with  Fortress  as  contingent  consideration.  Contingent
consideration is recorded when probable and reasonably estimable. The Company’s future share prices and shares outstanding cannot be estimated prior to
the issuance of the Annual Equity Fee due to the nature of its assets and the Company’s stage

Table of Contents

Notes to Financial Statements

of development. Due to these uncertainties, the Company has concluded that it is unable to reasonably estimate the contingent consideration until shares are
actually issued on January 1 of each year.

Pursuant to the Founders Agreement, the Company issued 1,742,449 shares of common stock to Fortress for the Annual Equity Fee, representing 2.5% of
the fully-diluted outstanding equity of Checkpoint on January 1, 2021. Because the number of outstanding shares issuable to Fortress was determinable on
January 1, 2021 prior to the issuance of the December 31, 2020 financial statements, the Company recorded approximately $4.6 million in research and
development expense and a credit to Common shares issuable - Founders Agreement during the year ended December 31, 2020.

Pursuant to the Founders Agreement, the Company issued 2,121,422 shares of common stock to Fortress for the Annual Equity Fee, representing 2.5% of
the fully-diluted outstanding equity of Checkpoint on January 1, 2022.  Because the number of outstanding shares issuable to Fortress was determinable on
January 1, 2022 prior to the issuance of the December 31, 2021 financial statements, the Company recorded approximately $6.6 million in research and
development expense and a credit to Common shares issuable - Founders Agreement during the year ended December 31, 2021.

Stock-Based Compensation Expenses

The Company expenses stock-based compensation over the requisite service period based on the estimated grant-date fair value of the awards and forfeiture
rates. The Company accounts for forfeitures as they occur.

The Company estimates the fair value of stock option grants using the Black-Scholes option pricing model. The assumptions used in calculating the fair
value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment. All
stock-based compensation costs are recorded in general and administrative or research and development costs in the Statements of Operations based upon
the underlying individual’s role at the Company.

Fair Value Measurement

The Company follows the accounting guidance in ASC 820 for its fair value measurements of financial assets and liabilities measured at fair value on a
recurring basis. Under this accounting guidance, fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid
to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that
should be determined based on assumptions that market participants would use in pricing an asset or a liability.

The accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories:

Level 1: Quoted  prices  in  active  markets  for  identical  assets  or

liabilities.

Level 2: Observable  inputs  other  than  Level  1  prices,  for  similar  assets  or  liabilities  that  are  directly  or  indirectly  observable  in  the

marketplace.

Level 3: Unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using
pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value
requires significant judgment or estimation.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair
value. Assets  and  liabilities  measured  at  fair  value  are  classified  in  their  entirety  based  on  the  lowest  level  of  input  that  is  significant  to  the  fair  value
measurement.

Certain of the Company’s financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate their fair
value due to their liquid or short-term nature, such as accounts payable and accrued expenses.

Revenue from Contracts with Customers

CHECKPOINT THERAPEUTICS, INC.
Notes to Financial Statements

The Company recognizes revenue under ASC 606, “Revenue from Contracts with Customers.”  The  core  principle  of  the  new  revenue  standard  is  that  a
company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which
the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:

●
●
●
●
●

Step 1: Identify the contract with the customer
Step 2: Identify the performance obligations in the contract
Step 3: Determine the transaction price
Step 4: Allocate the transaction price to the performance obligations in the contract
Step 5: Recognize revenue when the company satisfies a performance obligation

In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and
identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of
goods or services) if both of the following criteria are met:

●

●

The customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e.,
the good or service is capable of being distinct).
The entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to
transfer the good or service is distinct within the context of the contract).

If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified
that is distinct.

The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a
customer, excluding amounts collected on behalf of third parties (for example, some sales taxes). The consideration promised in a contract with a customer
may include fixed amounts, variable amounts, or both. When determining the transaction price, an entity must consider the effects of all of the following:

● Variable consideration
● Constraining estimates of variable consideration
●
● Noncash consideration
● Consideration payable to a customer

The existence of a significant financing component in the contract

Variable  consideration  is  included  in  the  transaction  price  only  to  the  extent  that  it  is  probable  that  a  significant  reversal  in  the  amount  of  cumulative
revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

The  transaction  price  is  allocated  to  each  performance  obligation  on  a  relative  standalone  selling  price  basis.  The  transaction  price  allocated  to  each
performance obligation is recognized when that performance obligation is satisfied, at a point in time or over time as appropriate.

Revenue for a sales-based or usage-based royalty promised in exchange for a license of intellectual property is recognized only when (or as) the later of the
following events occurs:

a. The subsequent sale or usage occurs.
b. The  performance  obligation  to  which  some  or  all  of  the  sales-based  or  usage-based  royalty  has  been  allocated  has  been  satisfied  (or  partially

satisfied).

F-10

Table of Contents

CHECKPOINT THERAPEUTICS, INC.
Notes to Financial Statements

Incremental  contract  costs  are  expensed  when  incurred  when  the  amortization  period  of  the  asset  that  would  have  been  recognized  is  one  year  or  less;
otherwise, incremental contract costs are recognized as an asset and amortized over time as services are provided to a customer.

Income Taxes

The Company records income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax effects
attributable  to  temporary  differences  between  the  financial  statement  carrying  amounts  of  existing  assets  and  liabilities  and  their  respective  income  tax
bases, and operating loss and tax credit carryforwards. The Company establishes a valuation allowance if management believes it is more likely than not
that the deferred tax assets will not be recovered based on an evaluation of objective verifiable evidence. For tax positions that are more likely than not of
being sustained upon audit, the Company recognizes the largest amount of the benefit that is greater than 50% likely of being realized. For tax positions that
are  not  more  likely  than  not  of  being  sustained  upon  audit,  the  Company  does  not  recognize  any  portion  of  the  benefit. As  of  December  31,  2021  and
December  31,  2020,  the  Company  determined,  based  upon  available  evidence,  that  it  is  more  likely  than  not  that  the  net  deferred  tax  asset  will  not  be
realized and, accordingly, has provided a full valuation allowance against its net deferred tax asset.

Net Loss per Share

Net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Since dividends are
declared, paid and set aside among the holders of shares of common stock and Class A common stock pro-rata on an as-if-converted basis, the two-class
method of computing net loss per share is not required. Diluted net loss per share does not reflect the effect of shares of common stock to be issued upon
the  exercise  of  stock  options  and  warrants,  as  their  inclusion  would  be  anti-dilutive.  The  following  table  summarizes  potentially  dilutive  securities
outstanding at December 31, 2021 and 2020 that were excluded from the computation of diluted net loss per share, as they would be anti-dilutive:

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law on March 27, 2020.
The CARES Act, among other things, includes tax provisions relating to refundable payroll tax credits, deferment of employer’s social security payments,
net operating loss utilization and carryback periods and modifications to the net interest deduction limitations. The CARES Act did not have a material
impact on the Company’s income tax provision for 2021. The Company will continue to evaluate the impact of the CARES Act on its financial position,
results of operations and cash flows.

On December 27, 2020, the President of the United States signed the Consolidated Appropriations Act, 2021 (“Consolidated Appropriations Act”) into law.
The  Consolidated Appropriations Act  is  intended  to  enhance  and  expand  certain  provisions  of  the  CARES Act,  allows  for  the  deductions  of  expenses
related  to  the  Payroll  Protection  Program  funds  received  by  companies,  and  provides  an  update  to  meals  and  entertainment  expensing  for  2021.  The
Consolidated Appropriations Act did not have a material impact to the Company’s income tax provisions for 2021 and 2020. The Company will continue to
evaluate the impact of the Consolidated Appropriations Act on its financial position, results of operations and cash flows.

Note 3 - License Agreements

Dana-Farber Cancer Institute

In March 2015, the Company entered into an exclusive license agreement with Dana-Farber Cancer Institute (“Dana Farber”) to develop a portfolio of fully
human immuno-oncology targeted antibodies. Under the terms of the license agreement, the Company paid Dana-Farber an up-front licensing fee of $1.0
million and, on May 11, 2015, granted Dana-Farber 500,000 shares, valued at $32,500 or $0.065 per share. The license agreement included an anti-dilution
clause  that  maintained  Dana-Farber’s  ownership  at  5%  until  such  time  that  the  Company  raised  $10  million  in  cash  in  exchange  for  common  shares.
Pursuant  to  this  provision,  on  September  30,  2015,  the  Company  granted  to  Dana-Farber  an  additional 136,830  shares  of  common  stock  valued  at
approximately  $0.6  million  and  the  anti-dilution  clause  thereafter  expired.  Dana-Farber  is  eligible  to  receive  payments  of  up  to  an  aggregate  of
approximately $21.5 million for each licensed product upon the Company’s successful achievement of certain clinical development, regulatory and first
commercial sale milestones. In addition, Dana-Farber is eligible to receive up to an aggregate of $60.0 million upon the Company’s successful achievement
of certain sales milestones based on aggregate net sales, in addition to royalty payments based on a tiered low to mid-single digit percentage of net sales.
Dana-Farber also receives an annual license maintenance fee of $50,000, which is creditable against future milestone payments or royalties. The portfolio
of antibodies licensed from Dana-Farber include antibodies targeting PD-L1, GITR and CAIX.

In December 2021 the Company expensed a non-refundable milestone payment of $4.0 million upon the first patient dosed in a Phase 3 clinical study of its
anti-PD-LI antibody cosibelimab, which is included in the Statements of Operations for the year ended December 31, 2021.

In  connection  with  the  license  agreement  with  Dana-Farber,  the  Company  entered  into  a  collaboration  agreement  with  TGTX,  which  was  amended  and
restated in June 2019, to develop and commercialize the anti-PD-L1 and anti-GITR antibody research programs in the field of hematological malignancies,
while the Company retains the right to develop and commercialize these antibodies in solid tumors. Michael Weiss, Chairman of the Board of Directors of
Checkpoint and Fortress’ Executive Vice Chairman, Strategic Development, is also the Executive Chairman, President and Chief Executive Officer and a
stockholder of TGTX. Under the terms of the original collaboration agreement, TGTX paid the Company $0.5 million, representing an upfront licensing
fee.  Upon  the  signing  of  the  amended  and  restated  collaboration  agreement  in  June  2019,  TGTX  paid  the  Company  an  additional  $1.0  million  upfront
licensing  fee.  The  Company  is  eligible  to  receive  substantive  potential  milestone  payments  for  the  anti-PD-L1  program  of  up  to  an  aggregate  of
approximately $27.6 million upon TGTX’s successful achievement of certain clinical development, regulatory and first commercial sale milestones. This is
comprised  of  up  to  approximately  $8.4  million  upon  TGTX’s  successful  completion  of  clinical  development  milestones,  and  up  to  approximately  $19.2
million upon regulatory filings and first commercial sales in specified territories. The Company is also eligible to receive substantive potential milestone
payments  for  the  anti-GITR  antibody  program  of  up  to  an  aggregate  of  approximately  $21.5  million  upon  TGTX’s  successful  achievement  of  certain
clinical  development,  regulatory  and  first  commercial  sale  milestones.  This  is  comprised  of  up  to  approximately  $7.0  million  upon  TGTX’s  successful
completion of clinical development milestones, and up to approximately $14.5 million upon first commercial sales in specified territories. In addition, the
Company is eligible to receive up to an aggregate of $60.0 million upon TGTX’s successful achievement of certain sales milestones based on aggregate net
sales for both programs, in addition to royalty payments based on a tiered low double-digit percentage of net sales. The Company also receives an annual
license maintenance fee, which is creditable against future milestone payments or royalties. TGTX also pays the Company for its out-of-pocket costs of
material used by TGTX for their development activities. For the years ended December 31, 2021 and 2020, the Company recognized approximately $0.2
million and $1.0 million, respectively, in revenue related to the collaboration agreement in the Statements of Operations. The revenue for the year ended
December 31, 2020 included a milestone of $925,000 upon the 12th patient dosed in a phase 1 clinical trial for the anti-PD-L1 antibody cosibelimab during
March 2020.

Adimab, LLC

CHECKPOINT THERAPEUTICS, INC.
Notes to Financial Statements

In October 2015, Fortress entered into a collaboration agreement with Adimab, LLC (“Adimab”) to discover and optimize antibodies using their proprietary
core  technology  platform.  Under  this  agreement, Adimab  optimized  cosibelimab  (formerly  referred  to  as  CK-301),  the  Company’s  anti-PD-L1  antibody
which it originally licensed from Dana-Farber. In January 2019, Fortress transferred the rights to the optimized antibody to the Company, and Checkpoint
entered into a collaboration agreement directly with Adimab on the same day. Under the terms of the agreement, Adimab is eligible to receive payments up
to an aggregate of approximately  $7.1 million upon the Company’s successful achievement of certain clinical development and regulatory milestones, of
which $4.8 million are due upon various filings for regulatory approvals to commercialize the product. In addition, Adimab is eligible to receive royalty
payments based on a tiered low single digit percentage of net sales.

In December 2021 the Company expensed non-refundable milestone payments of $2.4 million upon the first patient dosed in a Phase 3 clinical study of its
anti-PD-LI  antibody  cosibelimab,  which  is  included  in  the  Statements  of  Operations  for  the  year  ended  December  31,  2021.  The  expense  included  the
amount  due  for  the  first  patient  dosed  in  a  Phase  2  clinical  study  of  cosibelimab,  which  was  payable  upon  the  achievement  of  a  later-stage  clinical
milestone.

NeuPharma, Inc.

In  March  2015,  Fortress  entered  into  an  exclusive  license  agreement  with  NeuPharma,  Inc.  (“NeuPharma”)  to  develop  and  commercialize  novel
irreversible,  3rd  generation  EGFR  inhibitors,  including  olafertinib,  on  a  worldwide  basis  other  than  certain Asian  countries.  On  the  same  date,  Fortress
assigned all of its right and interest in the EGFR inhibitors to the Company. Under the terms of the license agreement, the Company paid NeuPharma an
up-front  licensing  fee  of  $1.0  million,  and  NeuPharma  is  eligible  to  receive  payments  of  up  to  an  aggregate  of  approximately  $40.0  million  upon  the
Company’s successful achievement of certain clinical development and regulatory milestones in up to three indications, of which $22.5  million  are  due
upon various regulatory approvals to commercialize the products. In addition, NeuPharma is eligible to receive payments of up to an aggregate of $40.0
million upon the Company’s successful achievement of certain sales milestones based on aggregate net sales, in addition to royalty payments based on a
tiered mid to high-single digit percentage of net sales.

Jubilant Biosys Limited

In  May  2016,  the  Company  entered  into  a  license  agreement  with  Jubilant  Biosys  Limited  (“Jubilant”),  whereby  the  Company  obtained  an  exclusive,
worldwide license to Jubilant’s family of patents covering compounds that inhibit BET proteins such as BRD4, including CK-103. Under the terms of the
license agreement, the Company paid Jubilant an up-front licensing fee of $2.0 million, and Jubilant is eligible to receive payments up to an aggregate of
approximately  $89.0  million  upon  the  Company’s  successful  achievement  of  certain  clinical  development  and  regulatory  milestones,  of  which  $59.5
million are due upon various regulatory approvals to commercialize the products. In addition, Jubilant is eligible to receive payments up to an aggregate of
$89.0 million upon the Company’s successful achievement of certain sales milestones based on aggregate net sales, in addition to royalty payments based
on a tiered low to mid-single digit percentage of net sales.

In  connection  with  the  license  agreement  with  Jubilant,  the  Company  entered  into  a  sublicense  agreement  with  TGTX,  a  related  party,  to  develop  and
commercialize the compounds licensed in the field of hematological malignancies, while the Company retains the right to develop and commercialize these
compounds  in  the  field  of  solid  tumors.  Under  the  terms  of  the  sublicense  agreement,  TGTX  paid  the  Company  $1.0  million,  representing  an  upfront
licensing  fee,  and  the  Company  is  eligible  to  receive  substantive  potential  milestone  payments  up  to  an  aggregate  of  approximately  $87.2  million  upon
TGTX’s successful achievement of clinical development and regulatory milestones. This is comprised of up to approximately $ 25.5 million upon TGTX’s
successful completion of three clinical development milestones for two licensed products, and up to approximately $61.7 million upon the achievement of
five  regulatory  approvals  and  first  commercial  sales  in  specified  territories  for  two  licensed  products.  In  addition,  the  Company  is  eligible  to  receive
potential milestone payments up to an aggregate of $89.0 million upon TGTX’s successful achievement of certain sales milestones based on aggregate net
sales by TGTX, for two licensed products, in addition to royalty payments based on a mid-single digit percentage of net sales by TGTX. TGTX also pays
the Company 50% of IND enabling costs and patent expenses. For each of the years ended

F-13

Table of Contents

CHECKPOINT THERAPEUTICS, INC.
Notes to Financial Statements

December  31,  2021  and  2020,  the  Company  recognized  approximately  $0.1  million  in  revenue  related  to  the  sublicense  agreement  in  the  Statements  of
Operations.

The collaborations with TGTX each contain single material performance obligations under Topic 606, which is the granting of a license that is functional
intellectual property. The Company’s performance obligation was satisfied at the point in time when TGTX had the ability to use and benefit from the right
to use the intellectual property. The performance obligations of the original agreements were satisfied prior to the adoption of Topic 606. The performance
obligation of the amendment to the collaboration agreement was satisfied in June 2019.

The  milestone  payments  are  based  on  successful  achievement  of  clinical  development,  regulatory,  and  sales  milestones.  Because  these  payments  are
contingent on the occurrence of a future event, they represent variable consideration and are constrained and included in the transaction price only when it is
probable  that  a  significant  reversal  in  the  amount  of  cumulative  revenue  recognized  will  not  occur.  The  sales-based  royalty  payments  are  recognized  as
revenue when the subsequent sales occur. The Company also receives variable consideration for certain research and development, out-of-pocket material
costs and patent maintenance related activities that are dependent upon the Company’s actual expenditures under the collaborations and are constrained and
included in the transaction price only when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Revenue
is  recognized  approximately  when  the  amounts  become  due  because  it  relates  to  an  already  satisfied  performance  obligation.  For  the  year  ended
December 31, 2021, the Company did not receive any milestones or royalty payments.

Note 4 - Related Party Agreements

Founders Agreement and Management Services Agreement with Fortress

Effective  March  17,  2015,  the  Company  entered  into  a  Founders Agreement  with  Fortress,  which  was  amended  in  July  2016  and  October  2017.  The
Founders Agreement provides, that in exchange for the time and capital expended in the formation of Checkpoint and the identification of specific assets
the  acquisition  of  which  resulted  in  the  formation  of  a  viable  emerging  growth  life  science  company,  the  Company  assumed  $2.8  million  in  debt  that
Fortress accumulated under a promissory note through National Securities Corporation for expenses and costs of forming Checkpoint, and the Company
shall also: (i) issue annually to Fortress, on January 1 of each year, shares of common stock equal to two and one-half percent ( 2.5%) of the fully-diluted
outstanding equity of Checkpoint at the time of issuance; (ii) pay an equity fee in shares of common stock, payable within five (5) business days of the
closing of any equity or debt financing for Checkpoint or any of its respective subsidiaries that occurs after the effective date of the Founders Agreement
and ending on the date when Fortress no longer has majority voting control in Checkpoint’s voting equity, equal to two and one-half percent ( 2.5%) of the
gross amount of any such equity or debt financing; and (iii) pay a cash fee equal to four and one half percent (4.5%)  of  Checkpoint’s  annual  net  sales,
payable on an annual basis, within ninety (90) days of the end of each calendar year. In the event of a change in control (as it is defined in the Founders
Agreement), Checkpoint will pay a one-time change in control fee equal to five times (5x) the product of (i) monthly net sales for the twelve (12) months
immediately preceding the change in control and (ii) four and one-half percent (4.5%). The Founders Agreement has a term of fifteen years, after which it
automatically  renews  for  one-year  periods  unless  Fortress  gives  the  Company  notice  of  termination.  The  Founders Agreement  will  also  automatically
terminate upon a change of control.

Effective March 17, 2015, the Company entered into a Management Services Agreement (the “MSA”) with Fortress. Pursuant to the terms of the MSA, for
a period of five (5) years, Fortress will render advisory and consulting services to the Company. Services provided under the MSA may include, without
limitation, (i) advice and assistance concerning any and all aspects of Checkpoint’s operations, clinical trials, financial planning and strategic transactions
and financings and (ii) conducting relations on behalf of the Company with accountants, attorneys, financial advisors and other professionals (collectively,
the  “Services”).  The  Company  is  obligated  to  utilize  clinical  research  services,  medical  education,  communication  and  marketing  services  and  investor
relations/public relation services of companies or individuals designated by Fortress, provided those services are offered at market prices. However, the
Company  is  not  obligated  to  take  or  act  upon  any  advice  rendered  from  Fortress  and  Fortress  shall  not  be  liable  for  any  of  the  Company’s  actions  or
inactions based upon their advice. Fortress and its affiliates, including all members of its Board of Directors, have been contractually exempt from fiduciary
duties to the Company relating to corporate opportunities. In consideration for the Services, the Company will pay Fortress an annual consulting fee of $0.5
million (the “Annual Consulting Fee”), payable in advance in equal quarterly installments on the first business day of each calendar quarter in each year,
provided, however, that such Annual Consulting Fee shall be increased

Leases

The Company is not a party to any leases for office space or equipment.

License Agreements

The  Company  has  undertaken  to  make  contingent  milestone  payments  to  the  licensors  of  its  portfolio  of  product  candidates.  In  addition,  the  Company
would pay royalties to such licensors based on a percentage of net sales of each product candidate following regulatory marketing approval (See Note 3).

Litigation

The Company recognizes a liability for a contingency when it is probable that liability has been incurred and when the amount of loss can be reasonably
estimated.  When  a  range  of  probable  loss  can  be  estimated,  the  Company  accrues  the  most  likely  amount  of  such  loss,  and  if  such  amount  is  not
determinable, then the Company accrues the minimum of the range of probable loss. As of December 31, 2021 and 2020, there was no litigation against the
Company.

Note 6 - Stockholders’ Equity

Common Stock

At the Company’s 2021 Annual Meeting of Stockholders held on June 9, 2021, its stockholders approved an amendment to its certificate of incorporation
to increase the number of authorized shares of common stock available to issue by 40,000,000  to 135,000,000 with a par value of $0.0001  per  share,  of
which 7,000,000 shares are designated as “Class A common stock.” The amendment was filed with the Secretary of State of the State of Delaware on June
10, 2021.

As  of  December  31,  2021  and  2020,  there  were 7,000,000  shares  of  Class A  common  stock  issued  and  outstanding  to  Fortress.  Dividends  are  to  be
distributed pro-rata to the Class A and common stockholders. The holders of common stock are entitled to one vote per share of common stock held. The
Class A common stockholders are entitled to a number of votes per share equal to 1.1 times a fraction, the numerator of which is the sum of the shares of
outstanding common stock and the denominator of which is the number of shares of Class A common stock. Accordingly, the holder of shares of Class A
common stock will be able to control or significantly influence all matters requiring approval by our stockholders, including the election of directors and the
approval of mergers or other business combination transactions. Each share of Class A common stock is convertible, at the option of the holder thereof, into
one (1) fully paid and non-assessable share of common stock subject to adjustment for stock splits and combinations.

The  Company  has  determined,  based  upon  available  evidence,  that  it  is  more  likely  than  not  that  the  net  deferred  tax  asset  will  not  be  realized  and,
accordingly, has provided a full valuation allowance against its net deferred tax asset. A valuation allowance of approximately $ 51.5  million  and  $37.3
million was recorded for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, the Company had federal and state net
operating loss carryforwards of approximately $143.6 million and $136.1 million, respectively. Approximately $ 112.6 million of the federal net operating
loss carryforwards and $1.6 million of the state net operating loss carryforwards can be carried forward indefinitely. The remaining $31.2 million of federal
and $134.5 million of state net operating loss carryforwards will begin to expire, if not utilized, by 2034  and 2034,  respectively.  The  Company  has  $1.2
million of research and development credit carryforwards and $1.0 million of orphan drug credit carryforwards, which will begin to expire, if not utilized,
by 2034.  Utilization  of  the  net  operating  loss  and  credit  carryforwards  may  be  subject  to  an  annual  limitation  due  to  the  ownership  change  limitations
provided by Section 382 of the Internal Revenue Code of 1986, as amended and similar state provisions.

There  are  no  significant  matters  determined  to  be  unrecognized  tax  benefits  taken  or  expected  to  be  taken  in  a  tax  return,  in  accordance  with ASC  740
“Income  Taxes”  (“ASC  740”),  which  clarifies  the  accounting  for  uncertainty  in  income  taxes  recognized  in  the  financial  statements,  that  have  been
recorded on the Company’s financial statements for the year ended December 31, 2021 and 2020. The Company does not anticipate a material change to
unrecognized tax benefits in the next twelve months.

Additionally, ASC 740 provides guidance on the recognition of interest and penalties related to income taxes. There were no interest or penalties related to
income taxes that have been accrued or recognized as of and for the period ended December 31, 2021 and 2020. The Company would classify interest and
penalties related to uncertain tax positions as income tax expense, if applicable.

The federal and state tax returns for the periods ended December 31, 2018, 2019 and 2020 are currently open for examination under the applicable federal
and state income tax statues of limitations. The Company is currently under examination by the New York City Department Finance for the 2016, 2017 and
2018 tax years. While the outcomes of the examinations are unknown, the Company does not expect any material adjustments.

DESCRIPTION OF SECURITIES

DESCRIPTION OF CAPITAL STOCK

The following description summarizes the material terms of Checkpoint capital stock. Because it is only a summary, it does not contain all the
information that may be important to you. For a complete description of our capital stock, you should refer to our certificate of incorporation, our bylaws
and to the provisions of applicable Delaware law.

Common Stock

Our common stock is traded on The Nasdaq Capital Market, or the Exchange, under the symbol “CKPT.”

The authorized capital stock of Checkpoint consists of 135,000,000 shares of common stock, of which 7,000,000 shares have been designated as

Class A common stock. The description of our Class A Common Stock in this item is for information purposes only. All of the Class A common stock has
been issued to Fortress. Class A common stock is identical to common stock other than as to voting rights, the election of directors for a definite period, and
conversion rights. On any matter presented to our stockholders for their action or consideration at any meeting of our stockholders (or by written consent of
stockholders in lieu of meeting), each holder of outstanding shares of Class A common stock will be entitled to cast for each share of Class A common
stock held by such holder as of the record date for determining stockholders entitled to vote on such matter, the number of votes that is equal to one and
one-tenth (1.1) times a fraction, the numerator of which is the sum of the shares of outstanding common stock and the denominator of which is the number
of shares of outstanding Class A common stock. Thus, the Class A common stock will at all times constitute a voting majority. For a period of ten (10)
years from the date of the first issuance of shares of Class A common stock expiring in 2025 (the “Class A Director Period”), the holders of record of the
shares of Class A common stock (or other capital stock or securities issued upon conversion of or in exchange for the Class A common stock), exclusively
and as a separate class, will be entitled to appoint or elect the majority of the directors of Checkpoint (the “Class A Directors”). Finally, each share of Class
A common stock is convertible, at the option of the holder, into one fully paid and nonassessable share of common stock (the “Conversion Ratio”), subject
to certain adjustments.

If Checkpoint at any time effects a subdivision of the outstanding common stock (or other capital stock or securities at the time issuable upon
conversion  of  the  Class A  common  stock)  by  any  stock  split,  stock  dividend,  recapitalization  or  otherwise,  the  applicable  Conversion  Ratio  in  effect
immediately before that subdivision will be proportionately decreased so that the number of shares of common stock (or other capital stock or securities at
the  time  issuable  upon  conversion  of  the  Class A  common  stock)  issuable  on  conversion  of  each  share  of  Class A  common  stock  will  be  increased  in
proportion to such increase in the aggregate number of shares of common stock (or other capital stock or securities at the time issuable upon conversion of
the Class A common stock) outstanding. If Checkpoint at any time combines the outstanding shares of common stock, the applicable Conversion Ratio in
effect  immediately  before  the  combination  will  be  proportionately  increased  so  that  the  number  of  shares  of  common  stock  (or  other  capital  stock  or
securities  at  the  time  issuable  upon  conversion  of  the  Class A  common  stock)  issuable  on  conversion  of  each  share  of  Class A  common  stock  will  be
decreased in proportion to such decrease in the aggregate number of shares of common stock (or other capital stock or securities at the time issuable upon
conversion  of  the  Class  A  common  stock)  outstanding.  Additionally,  if  any  reorganization,  recapitalization,  reclassification,  consolidation  or  merger
involving Checkpoint occurs in which the common stock (but not the Class A common stock) is converted into or exchanged for securities, cash or other
property (other than a transaction involving the subdivision or combination of the common stock), then, following any such reorganization, recapitalization,
reclassification, consolidation or merger, each share of Class A common stock becomes convertible into the kind and amount of securities, cash or other
property  which  such  Class A  Stockholder  would  have  been  entitled  to  receive  had  he  or  she  converted  the  Class A  Shares  immediately  before  said
transaction. In such case, appropriate adjustment (as determined in good faith by the Board of Directors of Checkpoint) will be made in the application of
the  provisions  of  Checkpoint’s Amended  and  Restated  Certificate  of  Incorporation  relating  the  subdivision  or  combination  of  the  common  stock  with
respect to the rights and interests thereafter of the holders of the Class A common stock, such that the provisions set forth in of Checkpoint’s Amended and
Restated Certificate of Incorporation relating to the subdivision or combination of the common stock (including the provisions with respect to changes in
and other

adjustments of the applicable Conversion Ratio) will thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property
thereafter deliverable upon the conversion of the Class A common stock. Checkpoint is not authorized to issue preferred stock.

Dividends

The holders of outstanding shares of our common stock, including Class A common stock, are entitled to receive dividends out of funds legally

available at the times and in the amounts that our board of directors may determine. All dividends are non-cumulative.

Voting Rights

The  holders  of  our  common  stock  are  entitled  to  one  vote  for  each  share  of  common  stock  held  on  all  matters  submitted  to  a  vote  of  the
stockholders, including the election of directors, except as to the Class A Directors during the Class A Director Period. Our certificate of incorporation and
bylaws do not provide for cumulative voting rights.

Liquidation and Dissolution

Upon our liquidation, dissolution, or  winding-up,  the  assets  legally  available  for  distribution  to  our  stockholders  would  be  distributable  ratably

among the holders of our common stock, including Class A common stock, outstanding at that time after payment of other claims of creditors, if any.

Other

The holders of our common stock have no preemptive, conversion, or subscription rights, and there are no redemption or sinking fund provisions

applicable to our common stock.

All of the outstanding shares of our common stock, including Class A common stock, are duly issued, fully paid and non-assessable.

General

One  or  more  series  of  debt  securities  may  be  sold  as  “original  issue  discount”  securities.  These  debt  securities  would  be  sold  at  a  substantial
discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. One or more series
of debt securities may be variable rate debt securities that may be exchanged for fixed rate debt securities.

United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in the applicable

prospectus supplement.

Debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange
rates,  commodity  prices,  equity  indices  or  other  factors.  Holders  of  such  debt  securities  may  receive  a  principal  amount  or  a  payment  of  interest  that  is
greater  than  or  less  than  the  amount  of  principal  or  interest  otherwise  payable  on  such  dates,  depending  upon  the  value  of  the  applicable  currencies,
commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date,
the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked and certain additional United States federal
income tax considerations will be set forth in the applicable prospectus supplement.

The  term  “debt  securities”  includes  debt  securities  denominated  in  U.S.  dollars  or,  if  specified  in  the  applicable  prospectus  supplement,  in  any

other freely transferable currency or units based on or relating to foreign currencies.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of $2,000 and any integral multiples
thereof.  Subject  to  the  limitations  provided  in  the  indenture  and  in  the  prospectus  supplement,  debt  securities  that  are  issued  in  registered  form  may  be
transferred  or  exchanged  at  the  principal  corporate  trust  office  of  the  trustee,  without  the  payment  of  any  service  charge,  other  than  any  tax  or  other
governmental charge payable in connection therewith.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on

behalf of, a depositary identified in the prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form.
Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the
depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such
depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary
arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be
described in the applicable prospectus supplement.

Governing Law

The indenture and the debt securities shall be construed in accordance with and governed by the laws of the State of New York.

DESCRIPTION OF UNITS

We may issue, in one more series, units comprised of shares of our common stock, warrants to purchase common stock, debt securities or any
combination of those securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder
of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the
securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

We may evidence units by unit certificates that we issue under a separate agreement. We may issue the units under a unit agreement between us
and one or more unit agents. If we elect to enter into a unit agreement with a unit agent, the unit agent will act solely as our agent in connection with the
units and will not assume any obligation or relationship of agency or trust for or with any registered holders of units or beneficial owners of units. We will
indicate the name and address and other information regarding the unit agent in the applicable prospectus supplement relating to a particular series of units
if we elect to use a unit agent.

We will describe in the applicable prospectus supplement the terms of the series of units being offered, including:

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities
may be held or transferred separately;

any provisions of the governing unit agreement that differ from those described herein;
and

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the
units.
