BUSINESS

All  references  in  this  report  to  “Corbus,”  the  “Company,”  “we,”  “us,”  or  “our”  mean  Corbus  Pharmaceuticals  Holdings,  Inc.  and  its  subsidiaries  unless  we  state

otherwise, or the context otherwise indicates.

Overview

We are a Phase 3, clinical-stage pharmaceutical company focused on the development and commercialization of novel therapeutics that target the endocannabinoid
system in the fields of autoimmunity, fibrosis, and cancer. We are developing a diverse pipeline of drug candidates across several distinct programs, including small molecules
as well as biologics, while also evaluating potential external candidates complimentary to our existing programs.

Our pipeline includes the following programs:

1. Lenabasum, a  novel,  synthetic,  oral,  cannabinoid  receptor  type  2  (CB2)  agonist  designed  to  resolve  chronic  inflammation,  limit  fibrosis  and  support  tissue  repair.
Lenabasum  is  in  clinical  development  for  treatment  of  autoimmune  diseases.  We  are  currently  evaluating  lenabasum  for  safety  and  efficacy  in  a  Phase  3  study  in
dermatomyositis, as well as a Phase 2 study in systemic lupus erythematosus (“SLE”).

2. Peripherally-restricted cannabinoid receptor type 1 (CB1) inverse agonists designed to normalize metabolic abnormalities or limit inflammation and fibrosis. We are
currently evaluating these compounds in pre-clinical studies for the treatment of metabolic disorders and for fibrotic disorders. We are evaluating certain compounds as
potential candidates for further clinical development.

3. Novel CB2 agonists designed to limit cancer cell growth directly and reduce the fibrosis and immunosuppression in the tumor microenvironment that are associated
with  tumor  growth,  metastasis,  and  resistance  to  treatment  with  drugs  such  as  checkpoint  inhibitors.  We  are  currently  evaluating  these  compounds  in  pre-clinical
studies  for  the  treatment  of  cancer,  in  combination  with  other  cancer  therapies  such  as  checkpoint  inhibitors.  We  are  evaluating  certain  compounds  as  potential
candidates for further clinical development.

Our Pipeline

Lenabasum for the Treatment of Autoimmune Diseases

Lenabasum selectively binds to CB2, which is preferentially expressed on activated immune cells, fibroblasts and other cell types, including muscle and bone cells.
Lenabasum reduces inflammation and limits fibrosis, without immunosuppression. Lenabasum inhibits production of inflammatory cytokines and eicosanoids, and stimulates
the production of mediators (Specialized Pro-resolving Lipid Mediators) that resolve inflammation. It inhibits transformation of fibroblasts into myofibroblasts and production
of fibrotic growth factors and collagen. These biologic effects have been demonstrated in cells, animal models, and humans.

The U.S. Food and Drug Administration, or FDA, granted lenabasum Orphan Drug Designation as well as Fast Track Status for systemic sclerosis and cystic fibrosis,
and  Orphan  Drug  Designation  for  dermatomyositis.  The  European  Medicines  Authority,  or  EMA,  has  granted  lenabasum  Orphan  Drug  Designation  for  systemic  sclerosis,
cystic fibrosis, and dermatomyositis.

In 2020, we announced that lenabasum did not meet the primary endpoints in our RESOLVE-1 Phase 3 study of lenabasum for the treatment of systemic sclerosis (the
“RESOLVE-1 Study”) or our Phase 2b study of lenabasum for the treatment of cystic fibrosis. Currently, no patients with systemic sclerosis or cystic fibrosis are being treated
with lenabasum. We are preparing the data from our RESOLVE-1 Study for publication and will decide on the next steps in the development process for systemic sclerosis
pending the outcome of our Phase 3 study of lenabasum for the treatment of dermatomyositis (the “DETERMINE Study”). We are preparing the data from our Phase 2b study
of lenabasum for the treatment of cystic fibrosis for publication, but currently we do not have plans for additional clinical studies in cystic fibrosis.

In  December  2018,  we  initiated  the  DETERMINE  Study,  our  Phase  3  double-blind  placebo-controlled  multi-center  international  clinical  study. The  DETERMINE
Study is fully enrolled with 176 patients. In January, 2021, we submitted a protocol amendment to the FDA to shorten the duration of the DETERMINE Study from 52 weeks
to 28 weeks. Subjects in the DETERMINE Study are randomized to receive lenabasum 20 mg twice per day, lenabasum 5 mg twice per day, or placebo twice per day in a 2:1:2
ratio.  The  primary  efficacy  outcome,  which  will  be  measured  at  week  28,  is  the  American  College  of  Rheumatology/European  League  Against  Rheumatism  2016  Total
Improvement  Score,  which  is  a  weighted  composite  measure  of  improvement  from  baseline  in  six  endpoints,  including  Physician  Global  Assessment  of  Disease  Activity,
Physician Global Assessment of Extramuscular Disease Activity, Patient Global Assessment of Disease Activity, Health Assessment Questionnaire (patient-reported disability),
Manual Muscle Testing, and muscle enzymes. Change from Baseline in the Cutaneous Dermatomyositis Activity and Severity Index activity (CDASI) score is one of several
secondary efficacy outcomes in the Phase 3 study. All subjects in the DETERMINE study have completed their week 28 visit, and some need to complete a 28-day safety
follow-up visit off study drug, with topline data expected in the second quarter of 2021.

The  design  of  our  DETERMINE  Study  was  based  on  positive  data  from  our  16-week,  Phase  2  double-blind,  placebo-controlled  single  center  study  of  safety  and
efficacy  of  lenabasum  in  patients  with  refractory  dermatomyositis  skin  disease  and  no  more  than  minimal  active  muscle  involvement  at  baseline.  Our  Phase  2  study  was
completed in October 2017 and showed improvement in skin disease with lenabasum treatment. All subjects remained on their background standard-of-care therapy, which, for
a  majority  of  patients,  included  immunosuppressive  therapies,  throughout  the  study.  Lenabasum  treatment  was  also  associated  with  numerically  better  improvements  in
multiple secondary efficacy outcomes, compared to placebo. Lenabasum was safely administered in this study, with no severe or serious adverse effects. Lenabasum was well-
tolerated, with no subjects discontinuing treatment because of an adverse effect related to lenabasum.

In our Phase 2 study of lenabasum for the treatment of dermatomyositis, the mean improvement (reduction) in the primary efficacy outcome, the CDASI score, was

9.3 points for lenabasum treatment versus a reduction of 3.7 points for placebo treatment (p = 0.04, 2-sided MMRM) at Week 16.

Phase 2 Dermatomyositis Study*

*Data on file.

Our  double-blind,  randomized,  placebo-controlled  Phase  2  study  of  lenabasum  in  systemic  lupus  erythematosus  (funded  by  the  National  Institutes  of  Health)  is
underway. The study is expected to dose 100 subjects at 15 sites. Enrollment is expected to be completed in the second fiscal quarter of 2021, and topline results are expected in
the second half of 2021.

Lenabasum has demonstrated acceptable safety and tolerability profiles in clinical studies to date.

CB1 Inverse Agonists for the Treatment of Metabolic and Fibrotic Diseases

CB1 is a receptor that is highly expressed in the nervous system and is also expressed in multiple cell lines outside the nervous system. A CB1 agonist is a compound
that initiates a pharmacologic response when it binds to CB1. Both CB1 antagonists and CB1 inverse agonists bind to, or block, CB1 and will reduce pharmacologic effects of
CB1 agonists. A CB1 inverse agonist binds CB1 but also induces a pharmacological response opposite to a CB1 agonist. Testing of CB1 antagonists and CB1 inverse agonists
in  animal  studies  has  shown  improvement  in  models  of  metabolic  diseases,  including  diet-induced  obesity,  diabetes,  diabetic  nephropathy,  diabetic  retinopathy,  metabolic
syndrome,  non-alcoholic  steatohepatitis,  fibrotic  diseases  including  (lung,  cardiac,  renal  disease,  and  liver  fibrosis),  and  other  diseases  including  ascites,  cognitive  defects,
Prader-Willi syndrome, and smoking cessation.

6

 
 
 
 
 
 
  
 
 
In the nervous system, CB1 regulates neurotransmission. Despite the positive results observed in animal studies of CB1 antagonists and CB1 inverse agonists for the
treatment of certain diseases, treatment with a particular CB1 inverse agonist, rimonabant (brand name, Acomplia), has also been associated with increased risk of anxiety,
depression, and suicidality in humans that led in October 2008 to the withdrawal of rimonabant from the European market, where it had been approved for treatment of obesity.

Importantly, data shows that the metabolic effects of blocking CB1 are mediated by CB1 in the periphery, not the central nervous system. This has led to efforts to
develop drugs that block CB1 only outside the central nervous system, to avoid adverse central nervous system effects seen with rimonabant when treating metabolic diseases.
When considering treatment of metabolic diseases, CB1 is known to have reciprocal functional activities with the incretins glucose-dependent insulinotropic polypeptide, or
GIP, and glucagon-like peptide-1, or GLP-1. This is of importance because recent data show that GIP/GLP-1 receptor agonists semaglutide and tirzepatide reduce obesity and
blood sugar in humans. In animal studies, GIP/GLP-1 receptor agonists are reported to have greater metabolic effects when used in combination with CB1 inhibitors than when
used as monotherapies. Beneficial effects of the combination of GIP/GLP-1 receptor agonists and CB1 inhibitors have been observed on body weight, fat mass, insulin action,
dyslipidemia, and hepatic steatosis in obese diabetic mice.

We have an exclusive worldwide license to develop, manufacture and market drug candidates from more than 600 compounds that have been developed primarily to

serve as CB1 inverse agonists with limited blood-brain-barrier penetration, to lessen risks of CB1-mediated central nervous system adverse effects.

We have identified and are conducting pre-clinical studies of several CB1 inverse agonists that have shown low exposure in the brain compared to the plasma. As

shown below, the area under the curve exposure in the brain is less than 5-10% of that in the plasma for some of our compounds in murine studies.

Some of these compounds have shown metabolic effects in a diet-induced obesity (DIO) murine model, preventing weight gain, or inducing weight loss and improving
glucose tolerance. In the experiment shown below, mice received a high fat diet for 16 weeks to induce obesity and glucose intolerance, then continued to receive high fat diet
while receiving oral compounds for 4 weeks. Treatment with CRB cmpd C gave dose dependent decreases in body weight that were similar to the positive control rimonabant.
At the same doses, but lower exposures, cmpd D appeared to prevent the body weight gains associated with vehicle, though the differences were not statistically significant.
However,  CRB  cmpd  D  gave  exposures  that  were  ~7-12  fold  lower  than  exposures  for  the  same  dose  of  CRB  cmpd  C,  so  results  for  CRB  cmpds  C  and  D  should  not  be
compared  directly.  CRB  cmpd  D  (5  mg/kg  and  10  mg/kg)  significantly  reduced  blood  glucose  levels  at  15  minutes  and  30  minutes  post  glucose  challenge  indicating
improvement in glucose tolerance. Note that 1 hour after the last study dose, the brain-plasma ratio for CRB cmpd C was 0.04 (5 mg/kg) and 0.02 (10 mg/kg) and for CRB
cmpd D was 0.04 for both doses.

Some  of  the  CB1  inverse  agonist  compounds  we  are  evaluating  have  demonstrated  anti-inflammatory  and  anti-fibrotic  effects,  as  well  as  the  inhibition  of

inflammatory cytokine production and the fibroblast to myofibroblast transition in pre-clinical studies.

For some of the CB1 inverse agonists, we will further evaluate drug exposure and CB1 occupancy in the brain, relative to the periphery, following chronic dosing in
several  animal  species  including  non-human  primates.  We  have  planned  other  pre-clinical  studies  to  fully  characterize  effects  of  these  compounds  in  animal  models  of
metabolic diseases and fibrosis. We also plan to test metabolic effects of our CB1 inverse agonists in combination with GLP-1 receptor agonists in animal models.

We believe that CB1 inverse agonists with limited CB1 receptor occupancy in the brain may potentially be a safe and effective treatment for metabolic, fibrotic and

other diseases. We intend to begin IND-enabling studies with a CB1 inverse agonist (yet to be selected) in 2021 and begin Phase 1 testing in 2022.

Novel CB2 agonists for treatment of cancer

The role of the endocannabinoid system in cancer has been widely researched and is a focus of current oncology research. Unregulated expression of cannabinoid
receptors and the elevated levels of endocannabinoids have been observed in a variety of cancer cells (skin, prostate, and colon cancer, hepato- cellular carcinoma, endometrial
sarcoma, glioblastoma multiforme, meningioma and pituitary adenoma, Hodgkin lymphoma, chemically induced hepatocarcinoma, mantel cell lymphoma). For example, CB2
expression in breast cancer biopsies correlates with negative clinical outcomes.

Pre-clinical  studies  of  CB2  agonists  in  tumor  models  in vitro  and  in  vivo  have  shown  positive  data,  with  a  decrease  in  tumor  growth  and  progression  observed.
Similarly, plant-derived cannabinoids such as tetrahydrocannabinol and cannabidiol have shown activity in pre-clinical models of cancer. Several pathways downstream from
CB2 have been proposed to mediate possible anti-cancer activities of CB2 agonists, as shown in the figure below.

Proposed CB2 Pathways for Anti-Cancer Activities*

*Pisanti  S,  Picardi  P,  D'Alessandro  A,  Laezza  C,  Bifulco  M.  The  endocannabinoid  signaling  system  in  cancer.  Trends  Pharmacol  Sci.  2013  May;34(5):273-82.  doi:
10.1016/j.tips.2013.03.003. Epub 2013 Apr 17. PMID: 23602129.

We have several novel CB2 agonists (which also function as CB1 agonists) that have reduced proliferation of some human tumor cell lines in vitro (some Her2+ breast
cancer, estrogen receptor+ breast cancer, triple negative breast cancer, lymphoma, non-small cell lung cancer, and glioblastoma cell lines) in our pre-clinical studies. A time-
dependent  reduction  in  phosphorylation  of  Her2  on  Her2+  HCC1954  breast  cancer  cells  in vivo  has  been  observed  as  shown  in  the  first  panel  in  the  figure  below.  In  this
experiment, HCC1954 Her2+ breast cancer cells were cultured with vehicle (DMSO) or CRB cmpd DD for different times. Densitometric analysis of the relative expression of
the phosphorylated Her2 vs. total Her2 protein was determined. CRB cmpd DD suppressed Her2 phosphorylation in vitro in HCC1954 cells.

We have conducted pre-clinical studies with our CB2 agonists that have shown a reduction in tumor volume of human Her2+ breast cancer cell HCC1954 (shown in
the second panel in the figure below) and a triple negative breast cancer in xenograft murine models. In the experiment shown below, female Balb/c nude mice (n = 10/group)
were injected in the flank with HCC1954 Her2+ breast cancer cells. Pharmacological treatments for 21 days with vehicle or CRB cmpd DD were started when tumors reached
90-180 mm3,with BKM-129 serving as a concurrent positive control. Tumor dimensions were measured using a caliper and used to calculate tumor volume.

* Data on file. Presented at New York Academy of Sciences Webinar on January 27, 2021.

We are conducting and plan to commence additional pre-clinical studies to define the range of anti-cancer effects of our CB2 agonist compounds and the underlying
pathways for these effects. We also plan to test efficacy of these compounds as monotherapy and in combination with other anti-cancer agents such as checkpoint inhibitors, in
animal models. We believe that it will be important to demonstrate that these compounds add to the efficacy seen with checkpoint inhibitors alone in animal models before
moving these compounds into clinical development. We intend to begin IND-enabling studies with a CB2 inverse agonist (yet to be selected) in 2021 and begin Phase 1 testing
in 2022.

Lenabasum Market Opportunity and Developed Competitive Landscape

Dermatomyositis

Dermatomyositis  is  a  serious  and  rare  autoimmune  idiopathic  inflammatory  myopathy  with  characteristic  cutaneous  findings.  About  80,000  individuals  in  the  U.S.,

Europe and Japan suffer from dermatomyositis. Dermatomyositis usually strikes adults, with common age of onset in adults between 50-60 years of age.

This  systemic  disorder  most  frequently  affects  the  skin  and  muscles,  and  dermatomyositis  can  also  include  interstitial  lung  disease/restrictive  lung  disease,  arthritis,
gastrointestinal and cardiac involvement. Inflammatory muscle disease associated with dermatomyositis can cause discomfort and significant weakness of the proximal muscles
of the arms and legs and of the trunk. Dermatomyositis can include damaging inflammation elsewhere in the body, for example: lung inflammation that leads to lung fibrosis
and  restrictive  lung  disease;  heart  inflammation  that  causes  arrhythmia,  congestive  heart  failure,  and  pericarditis;  inflammation  of  muscles  in  the  esophagus  that  causes
swallowing problems or aspiration pneumonia; and arthritis. Dermatomyositis patients may have active skin disease despite successful treatment of their muscle and/or lung
disease. The skin findings in dermatomyositis can be disfiguring and are inflammatory rashes characterized by redness and itching in exposed areas of the skin, around the eyes,
on the hands, and in a “shawl” distribution on the scalp, hands, upper back, and photo-exposed areas. Patients with dermatomyositis have an increased risk of malignancy, most
commonly in older patients. By itself, skin involvement in dermatomyositis has a large negative impact on quality of life, comparable to that of cutaneous lupus erythematosus,
and much higher than many dermatologic diseases.

Typically,  people  with  dermatomyositis  are  prescribed  immunosuppressive  therapies.  These  therapies  may  be  associated  with  significant  side  effects,  such  as  serious
infections.  FDA-approved  treatments  for  dermatomyositis  include  systemic  corticosteroids  and  adrenocorticotropic  hormone  analogue.  Additionally,  a  Phase  3  study  of
Octagam® 10% in dermatomyositis (NCT02728752) was reported in 2020 to achieve its primary endpoint.

We believe that a safe and effective drug that controls inflammation in the skin, muscles, and other organs and improves overall disease would address a significant unmet

medical need in dermatomyositis, particularly a non-immunosuppressive drug like lenabasum.

Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a prototypical autoimmune disease with a wide array of clinical manifestations, including arthritis, rash, photosensitivity, oral
ulcers, pleuritis, pericarditis, kidney problems, seizures and psychosis and blood cell abnormalities. About 550,000 individuals in the U.S., Europe and Japan suffer from SLE.
The musculoskeletal system is the most commonly involved system in SLE. Patients with SLE have an increased frequency of related autoimmune problems, such as Sjogren’s
syndrome and antiphospholipid syndrome that require additional treatments. Systemic lupus erythematosus may occur with other autoimmune conditions, such as thyroiditis,
hemolytic anemia, and idiopathic thrombocytopenia purpura.

The pathology of SLE involves chronic activation of the innate immune system by immune complexes, with activation of the complement cascade, increased production

of type 1 interferons and other mediators of inflammation, generation of specific immunity against self-antigens, and resultant tissue inflammation and damage.

Medicines specifically approved by the FDA for treatment of SLE are aspirin, hydroxychloroquine, corticosteroids (for example, prednisone), the corticotropin injection
Acthar® and the immunosuppressive drug Benlysta®. Other drugs that are not specifically FDA approved for SLE may be prescribed by physicians, including methotrexate,
mycophenolate, azathioprine, and cyclophosphamide. These treatments may be associated with significant side effects, such as serious infections.

We believe that a safe and effective drug that controls inflammation in the joints and skin as well as improves overall disease activity will address a significant unmet

medical need in SLE, particularly a non-immunosuppressive drug like lenabasum.

Sales and Marketing for Lenabasum

We  are  developing  our  commercial  capabilities  in  anticipation  of  potential  FDA  approval  for  lenabasum.  Our  intent  is  to  commercialize  lenabasum  ourselves  in  the
United  States  with  a  targeted  customer-facing  organization  to  call  on  treating  specialists  and  payers.  In  Europe  we  are  evaluating  potential  partnerships  for  the
commercialization of lenabasum as well as considering the option of commercializing ourselves. In Japan we granted exclusive license rights to Kaken Pharmaceutical Co.,
Ltd., or Kaken, for the commercialization of lenabasum for the treatment of systemic sclerosis and dermatomyositis.

CB1 Inverse Agonist Market Opportunity

There has been clinical interest in CB1 inverse agonists and antagonists for their potential applications in fibrosis, and metabolic disorders such as obesity. In obesity,
rimonabant  (brand  name  Acomplia),  a  CB1  inverse  agonist,  received  marketing  authorization  in  Europe  in  2006  prior  to  its  subsequent  withdrawal  in  2008  due  to  safety
concerns.  In  fibrosis,  there  are  two  companies  with  pre-clinical  stage  CB1  inverse  agonist  programs.  Goldfinch  Bio  has  a  preclinical  program  in  diabetic  nephropathy.
Inversago has preclinical programs in diabetic nephropathy, non-alcoholic steatohepatitis, and Prader-Willi syndrome.

We believe there is continued interest in the potential benefits of reducing obesity in diabetic and other at-risk populations. Recent data from two large clinical studies
have demonstrated significant effects of GLP-1 agonists on weight loss in a diabetic population. As of 2019, the market size for GLP-1 agonists was estimated at over $10
billion  and  expected  to  grow  based  on  a  2016  estimate  of  approximately  1.9  billion  adults  worldwide  who  are  overweight  and  at  increased  risk  of  developing  diabetes.We
believe a CB1 inverse agonist that avoids the potential central nervous system adverse effects associated with Acomplia could have potential clinical utility in helping treat
metabolic disorders.

Market Opportunity for CB2 Agonists That Add Benefit to Immune Checkpoint Inhibitors

The emergence of immune checkpoint inhibitors, or ICIs has transformed the treatment paradigm for multiple cancers. The ICI market reached $24 billion worldwide
in 2019 and is projected to grow to more than $50 billion by 2026. However, as of 2019, it is estimated that as few as 44% of patients are eligible to receive and only 12.5% of
all patients respond to an ICI. Even for patients who achieve a response, disease progression often occurs due to resistance mechanisms. Therefore, therapies that combine with
checkpoint inhibitors to improve outcomes, for example by altering the tumor microenvironment to reduce immunosuppression or fibrosis, may offer an attractive commercial
opportunity. We are currently planning to conduct pre-clinical studies of certain of our CB2 agonist compounds with ICIs for the treatment of certain cancer indications.

lenabasum for the treatment of all fibrotic diseases, encompassing the Company’s lead indications systemic sclerosis, cystic fibrosis and others. The patent provides intellectual
property protection in the United States for this use of lenabasum to February 12, 2034.

On September 20, 2018, we entered into an exclusive license agreement with Jenrin Discovery, LLC which provides us with an exclusive worldwide license to develop
and market cannabinoid compounds covered by the Jenrin issued patents and patent applications that cover the composition and method of use of selective cannabinoid receptor
modulators. The Jenrin intellectual property portfolio includes sixteen granted United States patents, one pending United States application and twenty-two granted or pending
foreign  patents  and  applications.  This  portfolio  includes  U.S.  Patent  No.  8,680,131,  which  granted  with  claims  covering  the  cannabinoid  receptor  blocker  CRB-4001  and
methods of using the same for treating obesity related disorders, diabetes, various inflammatory disorders, various cardiometabolic disorders, various hepatic disorders, and/or
various cancers. The licensed intellectual property portfolio provides intellectual property protection in the United States for CRB-4001 and these uses to July of 2033, not
including any potential patent term extension.

Lenabasum  has  been  granted  Orphan  Drug  Designation  for  cystic  fibrosis,  dermatomyositis  and  systemic  sclerosis  in  the  U.S.  and  in  the  European  Union  and  for
systemic sclerosis in Japan. In addition, in systemic sclerosis and in cystic fibrosis, lenabasum has been granted a Fast Track Designation by the FDA. Orphan designation for
lenabasum may be pursued for other inflammatory diseases in the U.S., Europe, and Japan. Orphan drug status provides seven years of market exclusivity in the U.S. and ten
years in Europe and Japan beginning on the date of drug approval.

Our commercial success depends in part on our ability to obtain and maintain patent and other proprietary protection for lenabasum and to operate without infringing the
proprietary  right  of  others  and  to  prevent  others  from  infringing  our  proprietary  rights. We  strive  to  protect  our  intellectual  property  through  a  combination  of  patents  and
trademarks as well as through the confidentiality provisions in our contracts. With respect to lenabasum, we endeavor to obtain and maintain patent protection in the U.S. and
internationally on all patentable aspects of the drug. We cannot be sure that the patents will be granted with respect to any patent applications we may own or license in the
future, nor can we be sure that any patents issued or licensed to us in the future will be useful in protecting our technology. For this and more comprehensive risks related to our
intellectual property, please see “Risk Factors—Risks Relating to Our Intellectual Property Rights.”

In  addition  to  patent  protection,  we  rely  on  trade  secrets  and  know-how  to  develop  and  maintain  our  competitive  position.  For  example,  aspects  of  our  proprietary
technology platform are based on unpatented trade secrets and know-how related to the manufacturing of lenabasum. Trade secrets and know-how can be difficult to protect.
We  seek  to  protect  our  proprietary  technology  and  processes,  in  part,  by  confidentiality  agreements  and  invention  assignment  agreements  with  our  employees,  consultants,
scientific  advisors,  contractors  and  commercial  partners.  These  agreements  are  designed  to  protect  our  proprietary  information  and,  in  the  case  of  the  invention  assignment
agreements, to grant us ownership of technologies that are developed through a relationship with a third party. We also seek to preserve the integrity and confidentiality of our
data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence
in these individuals, organizations and systems, agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our
trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our contractors use intellectual property owned by others in their
work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

13

 
 
 
 
 
 
 
 
 
 
We also seek and will continue to seek trademark protection in the United States and outside of the United States where available and when appropriate. We use and

intend to use these registered marks in connection with our pharmaceutical research and development as well as our product candidates.

Manufacturing and Supply for Lenabasum and Our Other Product Candidates

Lenabasum is a synthetic molecule and there are readily available supplies of all raw materials necessary for manufacturing lenabasum. We have developed and validated
a good manufacturing practice, or GMP, to manufacture lenabasum’s active pharmaceutical ingredient and drug product through our contract manufacturers. Our existing active
pharmaceutical  ingredient  contract  manufacturer  has  produced  multi-kilogram  scale  bulk  batches  under  GMP  for  our  on-going  clinical  studies  and  is  under  agreement  to
produce sufficient API required prior to submitting an NDA filing with the FDA. We do not own or operate manufacturing facilities for the production of lenabasum. We expect
to depend on third-party suppliers and manufacturing organizations for all our pre-clinical and clinical trial quantities of raw materials and drug substance.

Regulatory Matters

Government Regulation

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

Any  product  development  activities  related  to  lenabasum  or  products  that  we  may  develop  or  acquire  in  the  future  will  be  subject  to  extensive  regulation  by  various
government authorities, including the FDA, other federal, state and local agencies and comparable regulatory authorities in other countries, which regulate the design, research,
clinical and non-clinical development, testing, manufacturing, storage, distribution, import, export, labeling, advertising and marketing of pharmaceutical products and devices.
Generally, before a new drug can be sold, considerable data demonstrating its quality, safety and efficacy must be obtained, organized into a format specific to each regulatory
authority, submitted for review and approved by the regulatory authority. The data are often generated in two distinct development states: pre-clinical and clinical.

Development of Drugs in the United States

Lenabasum or other products that we may develop or acquire in the future must be approved by the FDA before they may be legally marketed in the United States. For
new chemical entities, the pre-clinical development stage generally involves synthesizing the active component, developing the formulation and determining the manufacturing
process, and drug stability as well as carrying out non-human toxicology, pharmacology and drug metabolism studies that support subsequent clinical testing. These pre-clinical
laboratory  and  animal  tests  are  often  performed  under  the  FDA’s  Good  Laboratory  Practices  regulations.  A  drug’s  sponsor  must  submit  the  result  of  the  pre-clinical  tests,
together with manufacturing information, analytical data and any available clinical data or literature and a proposed clinical protocol to the FDA as part of an IND application,
which is a request for authorization from the FDA to administer an investigational drug or biological product to humans. Similar filings are required in other countries.

14

 
 
 
 
 
 
 
 
 
 
 
The  clinical  stage  of  development  can  generally  be  divided  into  three  sequential  phases  that  may  overlap,  Phase  1,  Phase  2  and  Phase  3  clinical  trials.  In  Phase  1,
generally, small numbers of healthy volunteers are initially exposed to single escalating doses and then multiple escalating doses of the product candidate. The primary purpose
of  these  studies  is  to  assess  the  metabolism,  pharmacologic  action  and  general  safety  of  the  drug.  Phase  2  trials  typically  involve  studies  in  disease-affected  patients  to
determine the dose required to produce the desired benefits, common short-term side effects and risks. Phase 2 studies are typically well-controlled, closely monitored, and
conducted in a relatively small number of patients, usually involving no more than several hundred subjects. Phase 3 trials are intended to gather the additional information
about effectiveness and safety that is needed to evaluate the overall benefit-risk relationship of the drug and to provide an adequate basis for physician labeling. Phase 3 studies
usually include from several hundred to several thousand subjects and are closely controlled and monitored. In addition to these Phase 1-3 trials, other trials may be conducted
to gather additional safety, pharmacokinetic and pharmacodynamic information., Pharmaceutical products with active ingredients equal or similar to those already approved by
the FDA often have more streamlined development programs than compounds entirely new to the agency, often skipping Phase 1 and 2 trials.

A clinical plan must be submitted to the FDA prior to commencement of a clinical trial. If the FDA has concerns about the clinical plan or the safety of the proposed
studies, they may suspend or terminate the study at any time. Studies must be conducted in accordance with good clinical practice and reporting of study progress and any
adverse experiences is required. Studies are also subject to review by independent institutional review boards responsible for overseeing studies at particular sites and protecting
human research study subjects. An independent institutional review board may also suspend or terminate a study once initiated. Accordingly, we cannot be sure that submission
of an IND will result in the FDA allowing clinical trials to begin, or that once begun, issues will not arise that could cause the trial to be suspended or terminated.

Post-approval  studies,  sometimes  referred  to  as  Phase  4  clinical  trials,  may  be  conducted  after  initial  marketing  approval.  Sometimes,  these  studies  are  used  to  gain
additional experience from the treatment of patients in the intended therapeutic condition. In certain instances, the FDA may mandate the performance of Phase 4 studies. In
other situations, post-approval studies aim to gain additional indications for a medication.

Special Protocol Assessment

The Federal Food, Drug, and Cosmetic Act directs the FDA to meet with sponsors, pursuant to a sponsor’s written request, for the purpose of reaching agreement on the
design and size of clinical trials intended to form the primary basis of an efficacy claim in an NDA. If an agreement is reached, the FDA will reduce the agreement to writing
and make it part of the administrative record. This agreement is called a special protocol assessment, or SPA. While the FDA’s guidance on SPAs states that documented SPAs
should  be  considered  binding  on  the  review  division,  the  FDA  has  latitude  to  change  its  assessment  if  certain  exceptions  apply.  Exceptions  include  public  health  concerns
emerging that were unrecognized at the time of the protocol assessment, identification of a substantial scientific issue essential to the safety or efficacy testing that later comes
to light, a sponsor’s failure to follow the protocol agreed upon, or the FDA’s reliance on data, assumptions or information that are determined to be wrong.

Review and Approval in the United States

Following pivotal or Phase 3 trial completion, data are analyzed to determine safety and efficacy. Data are then filed with the FDA in a New Drug Application, or an
NDA, along with proposed labeling for the product and information about the manufacturing and testing processes and facilities that will be used to ensure product quality. In
the United States, FDA approval of an NDA must be obtained before marketing a pharmaceutical product. The NDA must contain proof of safety, purity, potency and efficacy,
which entails extensive pre-clinical and clinical testing.

The FDA will likely re-analyze the clinical trial data, which could result in extensive discussions between the FDA and us during the review process. The review and
evaluation  of  applications  by  the  FDA  is  extensive  and  time  consuming  and  may  take  several  years  to  complete.  The  FDA  may  conduct  a  pre-approval  inspection  of  the
manufacturing facilities for the new product to determine whether they comply with current good manufacturing practice requirements and may also audit data from clinical
and pre-clinical trials.

15

 
 
 
 
 
 
 
 
 
 
There is no assurance that the FDA will act favorably or quickly in making such reviews and significant difficulties or costs may be encountered in our efforts to obtain
FDA approvals. The FDA may require that certain contraindications, warnings or precautions be included in the product labeling, or may condition the approval of the NDA on
other  changes  to  the  proposed  labeling,  development  of  adequate  controls  and  specifications,  or  a  commitment  to  conduct  post-marketing  testing  or  clinical  trials  and
surveillance  programs  to  monitor  the  safety  of  approved  products  that  have  been  commercialized.  Further,  the  FDA  may  place  conditions  on  approvals  including  the
requirement for a risk evaluation and mitigation strategy, or REMS, to assure the safe use of the drug. If the FDA concludes a REMS is needed, the sponsor of the NDA must
submit a proposed REMS; the FDA will not approve the NDA without an approved REMS, if required. A REMS could include medication guides, physician communication
plans,  or  elements  to  assure  safe  use,  such  as  restricted  distribution  methods,  patient  registries  and  other  risk  minimization  tools.  Any  of  these  limitations  on  approval  or
marketing  could  restrict  the  commercial  promotion,  distribution,  prescription  or  dispensing  of  products.  Product  approvals  may  be  withdrawn  for  non-compliance  with
regulatory standards or if problems occur.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition
that affects fewer than 200,000 individuals in the United States. Orphan product designation must be requested before submitting an NDA. After the FDA grants orphan drug
designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan product designation does not convey any advantage in
or shorten the duration of regulatory review and approval process. In addition to the potential period of exclusivity, orphan designation makes a company eligible for grant
funding of up to $400,000 per year for four years to defray costs of clinical trial expenses, tax credits for clinical research expenses and potential exemption from the FDA
application user fee.

If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled
to orphan drug exclusivity, which means the FDA may not approve any other applications to market the same drug for the same indication for seven years, except in limited
circumstances, such as (i) the drug’s orphan designation is revoked; (ii) its marketing approval is withdrawn; (iii) the orphan exclusivity holder consents to the approval of
another applicant’s product; (iv) the orphan exclusivity holder is unable to assure the availability of a sufficient quantity of drug; or (v) a showing of clinical superiority to the
product  with  orphan  exclusivity  by  a  competitor  product.  If  a  drug  designated  as  an  orphan  product  receives  marketing  approval  for  an  indication  broader  than  what  is
designated, it may not be entitled to orphan drug exclusivity. We have received orphan drug designation for lenabasum for cystic fibrosis and systemic sclerosis. There can be
no assurance that we will receive orphan drug designation for lenabasum for DM, or additional orphan diseases.

Drug Development in Europe

In the European Union, our future products may also be subject to extensive regulatory requirements. Similar to the U.S., the marketing of medicinal products is subject
to  the  granting  of  marketing  authorizations  by  regulatory  agencies.  Also,  as  in  the  U.S.,  the  various  phases  of  pre-clinical  and  clinical  research  in  the  European  Union  are
subject to significant regulatory controls.

Review and Approval in the European Union

In the European Union, approval of new medicinal products can be obtained through one of three processes: the mutual recognition procedure, the centralized procedure

and the decentralized procedure. We intend to determine which process we will follow, if any, in the future.

Mutual  Recognition  Procedure:  An  applicant  submits  an  application  in  one  European  Union  member  state,  known  as  the  reference  member  state.  Once  the  reference
member  state  has  granted  the  marketing  authorization,  the  applicant  may  choose  to  submit  applications  in  other  concerned  member  states,  requesting  them  to  mutually
recognize the marketing authorizations already granted. Under this mutual recognition process, authorities in other concerned member states have 55 days to raise objections,
which must then be resolved by discussion among the concerned member states, the reference member state and the applicant within 90 days of the commencement of the
mutual recognition procedure. If any disagreement remains, all considerations by authorities in the concerned member states are suspended and the disagreement is resolved
through an arbitration process. The mutual recognition procedure results in separate national marketing authorizations in the reference member state.

16

 
 
 
 
 
 
 
 
 
 
 
Centralized Procedure: This procedure is currently mandatory for products developed by means of a biotechnological process and optional for new active substances and
other  “innovative  medicinal  products  with  novel  characteristics.”  Under  this  procedure,  an  application  is  submitted  to  the  European  Agency  for  the  Evaluation  of  Medical
Products. Two European Union member states are appointed to conduct an initial evaluation of each application. These countries each prepare an assessment report that is then
used as the basis of a scientific opinion of the Committee on Proprietary Medical Products. If this opinion is favorable, it is sent to the European Commission, which drafts a
decision. After consulting with the member states, the European Commission adopts a decision and grants a marketing authorization, which is valid throughout the European
Union and confers the same rights and obligations in each of the member states as a marketing authorization granted by that member state.

Decentralized Procedure: The most recently introduced of the three processes for obtaining approval of new medicinal processes in the European Union, the decentralized
procedure is similar to the mutual recognition procedure described above, but with differences in the timing that key documents are provided to concerned member states by the
reference member state, the overall timing of the procedure and the possibility of, among other things, “clock stops” during the procedure.

Post-Marketing Requirements

Following approval of a new product, a pharmaceutical company and the approved product are subject to continuing regulation by the FDA and other federal and state
regulatory authorities, including, among other things, monitoring and recordkeeping activities, reporting to applicable regulatory authorities of adverse experiences with the
product, providing the regulatory authorities with updated safety and efficacy information, product sampling and distribution requirements, and complying with promotion and
advertising  requirements,  which  include,  among  others,  standards  for  direct-to-consumer  advertising,  restrictions  on  promoting  drugs  for  uses  or  in  patient  populations  not
described  in  the  drug’s  approved  labeling  (known  as  “off-label  use”),  and  limitations  on  industry-sponsored  scientific  and  educational  activities.  Although  physicians  may
prescribe legally available drugs for off-label uses, manufacturers may not market or promote such off-label uses. Modifications or enhancements to the products or labeling or
changes of site of manufacture are often subject to the approval of the FDA and other regulators, which may or may not be received or may result in a lengthy review process.
The FDA regulations require the products be manufactured in specific approved facilities and in accordance with current good manufacturing practices, and NDA holders must
list  their  products  and  register  their  manufacturing  establishments  with  the  FDA.  These  regulations  also  impose  certain  organizational,  procedural  and  documentation
requirements with respect to manufacturing and quality assurance activities. Drug manufacturers and other entities involved in the manufacture and distribution of approved
drugs are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with current good manufacturing practice and other laws. NDA
holders using contract manufacturers, laboratories or packagers are responsible for the selection and monitoring of qualified firms. These firms are subject to inspections by the
FDA  at  any  time,  and  the  discovery  of  violative  conditions  could  result  in  enforcement  actions  that  interrupt  the  operation  of  any  such  facilities  or  the  ability  to  distribute
products manufactured, processed or tested by them.

Other Regulatory Matters

Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in addition to the FDA,
including,  in  the  United  States,  the  Centers  for  Medicare  &  Medicaid  Services,  or  CMS,  other  divisions  of  the  Department  of  Health  and  Human  Services,  the  Drug
Enforcement Administration, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental
Protection Agency, and state and local governments. These regulations include:

●   the  federal  healthcare  program  anti-kickback  law  which  prohibits,  among  other  things,  persons  from  soliciting,  receiving  or  providing  remuneration,  directly  or
indirectly, to induce either the referral of an individual, for an item or service or the purchasing or ordering of a good or service, for which payment may be made under federal
healthcare programs such as the Medicare and Medicaid programs;

17

 
 
 
 
 
 
 
 
 
● federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from
Medicare, Medicaid, or other government reimbursement programs that are false or fraudulent. The government may assert that a claim including items or services resulting
from a violation of the federal healthcare program anti-kickback law or related to off-label promotion constitutes a false or fraudulent claim for purposes of the federal false
claims laws;

● the Federal Physician Payments Sunshine Act within the ACA, and its implementing regulations, require that certain manufacturers of drugs, devices, biological and
medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report information related
to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of,
the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate family members; and

●   the  Health  Insurance  Portability  and  Accountability  Act,  or  HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  or
HITECH,  and  its  implementing  regulations,  imposes  certain  requirements  relating  to  the  privacy,  security  and  transmission  of  individually  identifiable  health  information.
Among  other  things,  HITECH  makes  HIPAA’s  privacy  and  security  standards  directly  applicable  to  “business  associates”—independent  contractors  or  agents  of  covered
entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil
monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates and possibly other persons, and gave state attorneys general
new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing
federal civil actions.

● applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act.

● The Lanham Act and federal antitrust laws.

● state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party
payer, including commercial insurers, and state 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 federal laws, thus complicating compliance efforts.

Distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, traceability, and storage and

security requirements intended to prevent the unauthorized sale of pharmaceutical products

The handling of any controlled substances must comply with the U.S. Controlled Substances Act and the Controlled Substances Import and Export Act. In the U.S., our

product candidate, lenabasum, is currently classified as Schedule I controlled substance as defined in the Controlled Substance Act (“CSA”).

Schedule  I  controlled  substances  are  pharmaceutical  products  subject  to  specific  regulations  under  the  CSA,  that  establishes,  among  other  things,  certain  registration,
manufacturing  quotas,  security,  recordkeeping,  reporting,  import,  export  and  other  requirements  administered  by  the  DEA.  All  parties  responsible  for  the  manufacturing,
distribution and testing the drug in clinical studies must apply for and obtain a license from the DEA before they are permitted to perform these activities with lenabasum.
Furthermore, these parties must have the security, control, recordkeeping, reporting and inventory mechanisms required by the DEA to prevent drug loss and diversion. All
licensed  facilities  are  required  to  renew  their  registrations  annually  if  they  intend  to  continue  to  work  with  our  drug.  The  DEA  conducts  periodic  inspections  of  certain
registered  establishments  that  handle  controlled  substances. We  have  been  working  with  our  manufacturers,  distributors,  exporters  and  clinical  sites  to  obtain  the  necessary
licenses to work with lenabasum. The parties responsible for the manufacturing, distribution and export of lenabasum have already applied for and have been granted DEA
licenses and a number of institutions responsible for conducting our current clinical studies have also been granted DEA licenses.

18

 
 
 
 
 
 
 
 
 
 
 
Individual states have also established controlled substance laws and regulations. Though state-controlled substances laws often mirror federal law because the states are
separate jurisdictions, they may separately schedule drugs, as well. While some states automatically schedule a drug based on federal action, other states schedule drugs through
rulemaking or a legislative action. The requirement for state registrations could also result in delay of the manufacturing, distribution of lenabasum or in the completion of our
current  clinical  studies.  We  and  our  manufacturing  vendors  and  clinical  sites  must  also  obtain  separate  state  registrations,  permits  or  licenses  in  order  to  be  able  to  obtain,
handle,  and  distribute  controlled  substances  for  clinical  trials  or  commercial  sale,  and  failure  to  meet  applicable  regulatory  requirements  could  lead  to  enforcement  and
sanctions by the states in addition to those from the DEA or otherwise arising under federal law.

Third-Party Payer Coverage and Reimbursement

Significant  uncertainty  exists  as  to  the  coverage  and  reimbursement  status  of  any  of  our  drug  candidates  that  ultimately  may  obtain  regulatory  approval.  In  both  the
United  States  and  foreign  markets,  our  ability  to  commercialize  our  product  candidates  successfully,  and  to  attract  commercialization  partners  for  our  product  candidates,
depends in significant part on the availability of adequate financial coverage and reimbursement from third-party payers, including, in the United States, governmental payers
such as the Medicare and Medicaid programs, managed care organizations, and private health insurers. Medicare is a federally funded program managed by the CMS, through
local fiscal intermediaries and carriers that administer coverage and reimbursement for certain healthcare items and services furnished to the elderly and disabled. Medicaid is
an insurance program for certain categories of patients whose income and assets fall below state defined levels and who are otherwise uninsured that is both federally and state
funded and managed by each state. The federal government sets general guidelines for Medicaid and each state creates specific regulations that govern its individual program.
Each payer has its own process and standards for determining whether it will cover and reimburse a procedure or particular product. Private payers often rely on the lead of the
governmental payers in rendering coverage and reimbursement determinations. Therefore, achieving favorable CMS coverage and reimbursement is usually a significant gating
issue  for  successful  introduction  of  a  new  product.  The  competitive  position  of  some  of  our  products  will  depend,  in  part,  upon  the  extent  of  coverage  and  adequate
reimbursement for such products and for the procedures in which such products are used. Prices at which we or our customers seek reimbursement for our product candidates
can be subject to challenge, reduction or denial by the government and other payers.

The United States Congress and state legislatures may, from time to time, propose and adopt initiatives aimed at cost containment, which could impact our ability to sell
our  product  candidates  profitably.  For  example,  the  two-year  spending  law  signed  by  the  President  of  United  States  on  February  9,  2018  includes  a  provision  raising  the
manufacturer discount to 70% in 2019 in the Medicare Part D coverage gap, also known as the “donut hole.” Under prior law, manufacturers were required to provide a 50%
discount on prescription drugs purchased in the donut hole. Manufacturers of branded drugs will face much higher liabilities from donut hole payments beginning in 2019,
estimated at multiple billions of dollars for some of the largest companies.

The cost of pharmaceuticals continues to generate substantial governmental and third-party payer interest. We expect that the pharmaceutical industry will experience
pricing  pressures  due  to  the  trend  toward  managed  healthcare,  the  increasing  influence  of  managed  care  organizations  and  additional  legislative  proposals.  Our  results  of
operations could be adversely affected by current and future healthcare reforms.

Some third-party payers also require pre-approval of coverage for new or innovative devices or drug therapies before they will reimburse healthcare providers that use
such  therapies.  While  we  cannot  predict  whether  any  proposed  cost-containment  measures  will  be  adopted  or  otherwise  implemented  in  the  future,  the  announcement  or
adoption of these proposals could have a material adverse effect on our ability to obtain adequate prices for our product candidates and operate profitably.

19

 
 
 
 
 
 
 
 
In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing
vary  widely  from  country  to  country.  For  example,  the  European  Union  provides  options  for  its  member  states  to  restrict  the  range  of  medicinal  products  for  which  their
national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the
medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be
no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements
for any of our products. Historically, products launched in the European Union do not follow price structures of the United States and generally tend to be significantly lower.

ITEM 1A. RISK FACTORS

An investment in our common stock is speculative and illiquid and involves a high degree of risk including the risk of a loss of your entire investment. You should carefully
consider  the  risks  and  uncertainties  described  below  and  the  other  information  contained  in  this  report  and  our  other  reports  filed  with  the  Securities  and  Exchange
Commission. The risks set forth below are not the only ones facing us. Additional risks and uncertainties may exist that could also adversely affect our business, operations and
financial condition. If any of the following risks actually materialize, our business, financial condition and/or operations could suffer. In such event, the value of our common
stock could decline, and you could lose all or a substantial portion of the money that you pay for our common stock.

Risks Related to Our Financial Position and Need for Capital

We are a clinical stage pharmaceutical company with a limited operating history.

Risk Related to our Company and our Business

We  are  a  clinical  stage  pharmaceutical  company  with  a  limited  operating  history.  We  must  complete  clinical  studies  and  other  development  activity  and  receive  regulatory
approval of a New Drug Application, or NDA, before commercial sales of a product can commence. The likelihood of success of our business plan must be considered in light
of the problems, substantial expenses, difficulties, complications and delays frequently encountered in connection with developing and expanding early-stage businesses and the
regulatory and competitive environment in which we operate. Pharmaceutical product development is a highly speculative undertaking, involves a substantial degree of risk and
is a capital-intensive business.

Accordingly,  you  should  consider  our  prospects  in  light  of  the  costs,  uncertainties,  delays  and  difficulties  frequently  encountered  by  companies  in  the  early  stages  of
development, especially clinical pharmaceutical companies such as ours. Potential investors should carefully consider the risks and uncertainties that a company with a limited
operating history will face. In particular, potential investors should consider that we cannot assure you that we will be able to:

● successfully implement or execute our current business plan, and we cannot assure you that our business plan is sound;
● successfully manufacture our clinical products and establish commercial drug supply;
● obtain Drug Enforcement Administration, or DEA, licenses necessary for the manufacturing of lenabasum and for evaluating lenabasum in our clinical trials;
● successfully complete the preclinical and clinical trials necessary to obtain regulatory approval for the marketing of our drug candidates, including lenabasum and our

cannabinoid drug candidates;

● secure market exclusivity and/or adequate intellectual property protection for our drug candidates;
● attract and retain an experienced management and advisory team;
● secure acceptance of our drug candidates in the medical community and with third party payors and consumers;
● launch commercial sales of our drug candidates, whether alone or in collaboration with others; and
● raise sufficient funds in the capital markets to effectuate our business plan.

If we cannot successfully execute any one of the foregoing, our business may not succeed and your investment will be adversely affected.

We have incurred operating losses in each year since our inception and expect to continue to incur substantial losses for the foreseeable future. We may never become
profitable or, if we achieve profitability, be able to sustain profitability.

We expect to incur substantial expenses without corresponding revenues unless and until we are able to obtain regulatory approval and successfully commercialize any of our
drug  candidates.  To  date,  we  have  not  generated  any  revenue  from  our  drug  candidates  and  we  expect  to  incur  significant  expense  to  complete  our  preclinical  and  clinical
program  for  our  drug  candidates  in  the  United  States  and  elsewhere.  We  may  never  be  able  to  obtain  regulatory  approval  for  the  marketing  of  our  drug  candidates  in  any
indication in the United States or internationally. Even if we are able to commercialize our drug candidates, there can be no assurance that we will generate significant revenues
or ever achieve profitability. Our net losses for the years ended December 31, 2020 and December 31, 2019 were approximately $111,269,000 and $71,454,000, respectively.
As of December 31, 2020, we had an accumulated deficit of approximately $304.1 million.

We may elect to pursue FDA approval for lenabasum in other indications and for other drug candidates, which will result in significant additional research and development
expenses. As a result, we expect to continue to incur substantial losses for the foreseeable future, and these losses will increase. We are uncertain when or if we will be able to
achieve  or  sustain  profitability.  If  we  achieve  profitability  in  the  future,  we  may  not  be  able  to  sustain  profitability  in  subsequent  periods.  Failure  to  become  and  remain
profitable would impair our ability to sustain operations and adversely affect the price of our common stock and our ability to raise capital.

Our cash or cash equivalents will only fund our operations for a limited time and we will need to raise additional capital to support our development and commercialization
efforts.

We are currently operating at a loss and expect our operating costs will increase significantly as we incur further costs related to preclinical development and the clinical trials
for our drug candidates. As of December 31, 2020, we held cash and cash equivalents of approximately $85.4 million.

On January 26, 2018, we entered into the Cystic Fibrosis Program Related Investment Agreement (the “Investment Agreement”) with the Cystic Fibrosis Foundation, a non-
profit drug discovery and development corporation, pursuant to which we received a development award for up to $25 million in funding (the “2018 CFF Award”) to support a
Phase 2b clinical trial (the “Phase 2b Clinical Trial”) of lenabasum in patients with cystic fibrosis, of which we received $22.5 million to date. The remainder of the 2018 CFF
Award is payable to us incrementally upon the achievement of the remaining milestones related to the progress of the Phase 2b Clinical Trial, as set forth in the Investment
Agreement and we expect to receive the remainder before the end of the first half of 2021.

On  January  3,  2019,  we  entered  into  a  strategic  collaboration  with  Kaken  Pharmaceutical  Co.,  Ltd.  (“Kaken”)  for  the  development  and  commercialization  in  Japan  of
lenabasum for the treatment of SSc and DM. Under the terms of the agreement, Kaken receives an exclusive license to commercialize and market lenabasum in Japan for SSc
and DM. Kaken made an upfront payment to us of $27 million. We are eligible to receive in addition up to $173 million upon achievement of certain regulatory, development
and sales milestones as well as double-digit royalties.

On July 28, 2020, we entered into a Loan and Security Agreement (the “Loan Agreement”) with our subsidiary, Corbus Pharmaceuticals, Inc., as borrower, us, as guarantor,
each lender party thereto (the “Lenders”), K2 HealthVentures LLC (“K2HV”), an unrelated third party, as administrative agent for the Lenders, and Ankura Trust Company,
LLC,  an  unrelated  third  party,  as  collateral  agent  for  the  Lenders,  pursuant  to  which  K2HV  may  provide  us  with  term  loans  in  an  aggregate  principal  amount  of  up  to  a
$50,000,000.

On August 7, 2020, we entered into an Open Market Sale AgreementSM (the “August 2020 Sale Agreement”) with Jefferies LLC (“Jefferies”), as sales agent, pursuant to which
we may issue and sell, from time to time, through Jefferies, shares of our common stock. We will pay Jefferies a commission of 3.0% of the aggregate gross proceeds from each
sale  of  common  stock  and  have  agreed  to  provide  Jefferies  with  customary  indemnification  and  contribution  rights.  We  have  also  agreed  to  reimburse  Jefferies  for  certain
specified expenses. As of August 7, 2020, we were authorized to offer and sell up to $150 million of our common stock pursuant to the August 2020 Sale Agreement. As of
December  31,  2020  we  have  sold  15,546,151  shares  of  our  common  stock  for  gross  proceeds  to  us  totaling  $21,404,000,  less  issuance  costs  incurred  of  approximately
$642,000.

We expect the cash and cash equivalents of approximately $85.4 million at December 31, 2020, $58.9 million of proceeds raised from the August 2020 Sale Agreement from
January 1, 2021 through March 15, 2021, and the remaining $2.5 million of proceeds that we expect to receive under the 2018 CFF Award before the end of the first half of
2021 to be sufficient to meet our operating and capital requirements into 2024, based on planned expenditures.

22

 
 
 
 
 
 
 
 
 
 
 
 
We may seek additional capital through a combination of private and public equity offerings, debt financings and strategic collaborations. Debt financing, if obtained, may
involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, and could increase our expenses and
require that our assets secure such debt.

Equity  financing,  if  obtained,  could  result  in  dilution  to  our  then  existing  stockholders  and/or  require  such  stockholders  to  waive  certain  rights  and  preferences.  If  such
financing is not available on satisfactory terms, or is not available at all, we may be required to delay, scale back or eliminate the development of business opportunities and our
operations  and  financial  condition  may  be  materially  adversely  affected.  We  can  provide  no  assurances  that  any  additional  sources  of  financing  will  be  available  to  us  on
favorable terms, if at all. In addition, if we are unable to secure sufficient capital to fund our operations, we may choose to pursue, as an alternative, strategic collaborations that
could require us to share commercial rights to our drug candidates with third parties in ways that we currently do not intend or on terms that may not be favorable to us. If we
choose to pursue additional indications and/or geographies for our drug candidates or otherwise expand more rapidly than we presently anticipate we may also need to raise
additional capital sooner than expected.

Our Loan and Security Agreement contains restrictive and financial covenants that may limit our operating flexibility.

Our Loan Agreement with K2HV for up to $50,000,000 is secured by a lien covering substantially all of our personal property, excluding intellectual property.

The  Loan  Agreement  contains  customary  representations,  warranties  and  covenants.  including  restrictive  covenants  by  the  Company  and  Borrower  limiting  additional
indebtedness,  liens,  mergers  and  acquisitions,  dispositions,  investments,  distributions,  subordinated  debt,  transactions  with  affiliates  and  fundamental  changes.  We  therefore
may not be able to engage in any of the foregoing types of transactions unless we obtain the consent of K2 Health Ventures or prepay the outstanding amount under the Loan
Agreement. The Loan Agreement also contains certain financial covenants, including requirements to maintain unrestricted cash in the amount of $10,000,000 or the amount of
all principal loans outstanding if certain regulatory and developmental milestones do not occur.

The restrictions and covenants in the Loan Agreement, as well as those contained in any future debt financing agreements that we may enter into, may restrict our ability to
finance our operations and engage in, expand or otherwise pursue our business activities and strategies. Our ability to comply with these covenants and restrictions may be
affected by events beyond our control, and breaches of these covenants and restrictions could result in a default under the loan agreement and any future financing agreements
that we may enter into.

Risks Related to Product Development, Regulatory Approval, Manufacturing and Commercialization

Our  near-term  success  is  substantially  dependent  upon  successful  development  of  lenabasum,  our  first  compound  to  enter  clinical  development,  and  our  longer-term
success is dependent upon successful development of other compounds in our pipeline or that we may acquire. If we are unable to generate revenues from lenabasum, or
any other product candidates our ability to create stockholder value will be limited.

We do not generate revenues from any FDA approved drug products. Our current business currently depends heavily on the successful development, regulatory approval, and
commercialization of lenabasum, which may never occur. Currently, our most advanced product candidate is lenabasum, for which we have completed a Phase 3 double-blind,
placebo-controlled  study  in  systemic  sclerosis  and  a  double-blind,  placebo-controlled  study  Phase  2b  study  in  cystic  fibrosis,  and  have  an  ongoing  double-blind,  placebo-
controlled study Phase 3 study in DM. The Phase 3 study in systemic sclerosis and Phase 2 study in cystic fibrosis did not meet their primary efficacy endpoints. There is no
guarantee that our Phase 3 trial in DM will be successful or that, if positive, it would support FDA approval of a New Drug Application for lenabasum for treatment of DM.

We are currently conducting pre-clinical trials and testing for a number of CB1 inverse agonists and CB2 agonists. We note that most drug candidates never reach the clinical
development stage and even those that do have only a small chance of successfully completing clinical development and gaining regulatory approval.

The  coronavirus  COVID-19  pandemic  or  the  widespread  outbreak  of  any  other  communicable  disease  could  materially  and  adversely  affect  our  business,  financial
condition and results of operations.

We  face  risks  related  to  health  epidemics  or  outbreaks  of  communicable  diseases,  for  example,  the  outbreak  around  the  world  of  the  highly  transmissible  and  pathogenic
coronavirus, COVID-19. The outbreak of such communicable diseases, including COVID-19 and variants, could result in a widespread health crisis that could adversely affect
general commercial activity and the economies and financial markets of many countries.

In December 2019, a novel strain of coronavirus, COVID-19, was reported to have surfaced in Wuhan, China and on March 11, 2020 was declared a pandemic by the World
Health Organization. The extent to which COVID-19 may impact our preclinical and clinical trial operations will depend on future developments, which are highly uncertain
and cannot be predicted with confidence, such as the duration of the outbreak, the severity of COVID-19, including its variants, and the effectiveness of actions to contain and
treat COVID-19, including the effectiveness of vaccines and the ability of governments and healthcare providers to administer vaccines quickly and effectively

To limit the spread of COVID-19, governments have taken various actions from time to time including the issuance of travel restrictions, complete or partial prohibitions of
non-essential  activities,  restrictions  or  shutdowns  of  non-essential  businesses,  stay-at-home  orders  and  social  distancing  guidelines.  Such  events  may  result  in  a  period  of
business, supply and drug product manufacturing disruption, and in reduced operations, any of which could materially affect our business, financial condition and results of
operations.

Some  of  our  business  partners  and  manufacturing  operations,  including  production  of  our  commercial  and  clinical  active  pharmaceutical  ingredient  of  lenabasum,  are
conducted  internationally  and  may  be  impacted  by  the  global  spread  of  COVID-19.  Although  we  have  not  experienced  any  material  disruptions  to  these  manufacturing
operations or any material delays in shipping our commercial and clinical active pharmaceutical ingredient to our clinical trial sites to date, the continued impact resulting from
the COVID-19 outbreak where we have operations, or if the COVID-19 outbreak in these areas were to increase in severity, and the measures taken by the governments of
countries affected could adversely affect our business, financial condition or results of operations by limiting our ability to manufacture or ship materials or forcing temporary
closure of facilities that we rely upon.

The global spread of COVID-19 has created significant volatility and uncertainty in global financial markets and may materially affect us economically and such conditions
continue to persist. While the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread pandemic could result in
significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or
market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common shares.

The continued spread of COVID-19 globally, and the resulting travel restrictions in place by governments to help stop the spread of COVID-19, could adversely impact our
clinical trial operations, including the ability of our patients, principal investigators and site staff to travel to our clinical trial sites, and our ability to recruit and retain principal
investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 if an outbreak occurs in their geography. We cannot predict whether
clinical testing sites will withdraw from participation in any of our studies temporarily or permanently. In addition, if the patients enrolled in our clinical trials become infected
with COVID-19, we may have more adverse events and deaths in our clinical trials as a result. We may also face difficulties enrolling patients in our clinical trials if the patient
populations that are eligible for our clinical trials are impacted by the coronavirus disease. Vulnerable patients, including patients with autoimmune disorders like the patients
enrolled in our clinical trials, may be at a higher risk of contracting COVID-19 and may experience more severe symptoms from the disease, adversely affecting our chances for
regulatory approval or requiring further clinical studies.

The COVID-19 outbreak may also affect the ability of our staff and the parties we work with to carry out our non-clinical, clinical, and drug development and manufacturing
activities.  We  rely  on  clinical  sites,  investigators  and  other  study  staff,  consultants,  independent  contractors,  contract  research  organizations  and  other  third-party  service
providers  to  assist  us  in  managing,  monitoring  and  otherwise  carrying  out  our  nonclinical  studies  and  clinical  trials.  We  also  rely  on  consultants,  independent  contractors,
contract  development  and  manufacturing  organizations,  and  other  third-party  service  providers  to  assist  us  in  managing,  monitoring  and  otherwise  carrying  out  our  API
production, formulation, and drug manufacturing activities. COVID-19 may affect the ability of any of these external people, organizations, or companies to devote sufficient
time and resources to our programs or to travel to perform work for us.

Potential negative impacts of the COVID-19 outbreak on the conduct of current or future clinical studies include delays in gaining feedback from regulatory agencies, starting
new clinical studies, and recruiting subjects to studies that are enrolling. Although we have implemented remote data monitoring procedures for our clinical trials, the potential
negative impacts also include inability to have study visits at study sites, incomplete collection of safety and efficacy data, and higher rates of drop-out of subjects from ongoing
studies, delays in site entry of study data into the data base, delays in monitoring of study data because of restricted physical access to study sites, delays in site responses to
queries, delays in data-base lock, delays in data analyses, delays in time to top-line data, and delays in completing study reports. New or worsening COVID-19 disruptions or
restrictions could have the potential to further negatively impact our non-clinical studies, clinical trials, and drug manufacturing activities.

As a result of the factors described above, the expected timeline for data readouts of our drug manufacturing activities, non-clinical studies, clinical trials, and certain regulatory
filings  may  be  negatively  impacted,  which  would  adversely  affect  our  ability  to  obtain  regulatory  approval  for  and  to  commercialize  our  product  candidates,  increase  our
operating expenses and have a material adverse effect on our financial results.

If we are not able to obtain any required regulatory approvals for our drug candidates, we will not be able to commercialize our product candidates and our ability to
generate revenue will be limited.

Our clinical trials may be unsuccessful, which would materially harm our business. Even if our ongoing clinical trials are successful, we will be required to conduct additional
clinical trials to establish the safety and efficacy of our drug candidates, before a New Drug Application, or NDA, can be filed with the FDA for marketing approval of any of
our drug candidates.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Clinical testing is expensive, is difficult to design and implement, can take many years to complete and is uncertain as to outcome. Success in early phases of pre-clinical and
clinical trials does not ensure that later clinical trials will be successful, and interim results of a clinical trial do not necessarily predict final results. A failure of one or more of
our clinical trials can occur at any stage of testing. We may experience numerous unforeseen events during, or as a result of, the clinical trial process that could delay or prevent
our ability to receive regulatory approval or commercialize our drug candidates. The research, testing, manufacturing, labeling, packaging, storage, approval, sale, marketing,
advertising  and  promotion,  pricing,  export,  import  and  distribution  of  drug  products  are  subject  to  extensive  regulation  by  the  FDA  and  other  regulatory  authorities  in  the
United States and other countries, which regulations differ from country to country. We are not permitted to market any of our drug candidates as prescription pharmaceutical
products in the United States until we receive approval of an NDA from the FDA or in foreign markets until we receive the requisite approval from comparable regulatory
authorities in such countries. In the United States, the FDA generally requires the completion of clinical trials of each drug to establish its safety and efficacy and extensive
pharmaceutical development to ensure its quality before an NDA is approved. Regulatory authorities in other jurisdictions impose similar requirements. Of the large number of
drugs in development, only a small percentage result in the submission of an NDA to the FDA and even fewer are eventually approved for commercialization. We have never
submitted an NDA to the FDA or any comparable applications to other regulatory authorities. If our development efforts for our drug candidates, including regulatory approval,
are not successful for our planned indications, or if adequate demand for our drug candidates is not generated, our business will be harmed.

24

 
 
Receipt of necessary regulatory approval is subject to a number of risks, including the following:

■ the FDA or comparable foreign regulatory authorities or institutional review boards, or IRBs, may disagree with the design or implementation of our clinical trials,

including the shortened duration of treatment in our DETERMINE phase 3 study of lenabasum for treatment of dermatomyositis from 52 weeks to 26 weeks;

■ we may not be able to provide acceptable evidence of the safety and efficacy of our drug candidates;

■ the results of our clinical trials may not be satisfactory or may not meet the level of statistical or clinical significance required by the FDA, the European Medicines

Agency, or EMA, or other comparable foreign regulatory authorities for marketing approval;

■ the dosing of our drug candidates in a particular clinical trial may not be at an optimal level;

■ patients in our clinical trials may suffer adverse effects for reasons that may or may not be related to our drug candidates;

■ the data collected from clinical trials may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory approval in the United

States or elsewhere;

■ the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  the  manufacturing  processes  or  facilities  of  third-party  manufacturers  with  which  we

contract for clinical and commercial supplies;

■ the  approval  policies  or  regulations  of  the  FDA  or  comparable  foreign  regulatory  authorities  may  significantly  change  in  a  manner  rendering  our  clinical  data

insufficient for approval; and

■ the FDA or comparable foreign regulatory authorities may decide that the clinical trial endpoints we have chosen, the statistical analysis plans that we use, or any other

parameter that we rely on to show the safety and efficacy of our drugs, are not parameters that can be used to support approval of our products.

Failure to obtain regulatory approval for any of our drug candidates for the foregoing or any other reasons will prevent us from commercializing such product candidate as a
prescription product, and our ability to generate revenue will be materially impaired. We cannot guarantee that regulators will agree with the endpoints that we have chosen to
use in our clinical trials, our assessment of the results of our clinical trials or that such trials will be considered by regulators to have shown safety or efficacy of our product
candidates. The FDA, EMA and other regulators have substantial discretion in the approval process and may refuse to accept any application or may decide that our data is
insufficient  for  approval  and  require  additional  clinical  trials,  or  pre-clinical  or  other  studies.  In  addition,  varying  interpretations  of  the  data  obtained  from  pre-clinical  and
clinical testing could delay, limit or prevent regulatory approval of a product candidate.

We  have  only  limited  experience  in  filing  the  applications  necessary  to  gain  regulatory  approvals  and  expect  to  rely  on  consultants  and  third  party  contract  research
organizations, or CROs, with expertise in this area to assist us in this process. Securing FDA approval requires the submission of pre-clinical, clinical and/or pharmacokinetic
data,  information  about  product  manufacturing  processes  and  inspection  of  facilities  and  supporting  information  to  the  FDA  for  each  therapeutic  indication  to  establish  a
product candidate’s safety and efficacy for each indication. Our drug candidates may prove to have undesirable or unintended side effects, toxicities or other characteristics that
may preclude our obtaining regulatory approval or prevent or limit commercial use with respect to one or all intended indications.

The process of obtaining regulatory approvals is expensive, often takes many years, if approval is obtained at all, and can vary substantially based upon, among other things, the
type, complexity and novelty of the product candidates involved, the jurisdiction in which regulatory approval is sought and the substantial discretion of regulatory authorities.
Changes in the regulatory approval policy during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for
a submitted product application may cause delays in the approval or rejection of an application. Regulatory approval obtained in one jurisdiction does not necessarily mean that
a product candidate will receive regulatory approval in all jurisdictions in which we may seek approval, but the failure to obtain approval in one jurisdiction may negatively
impact our ability to seek approval in a different jurisdiction. Failure to obtain regulatory marketing approval for any of our drug candidates in any indication will prevent us
from commercializing such product candidates, and our ability to generate revenue will be materially impaired.

Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial
results.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. Our
drug candidates are in various stages of preclinical and clinical testing. Preclinical tests are performed at an early stage of a product's development and provide information
about a drug candidate's safety and effectiveness on laboratory animals. Preclinical tests can last years. If a product passes its preclinical tests satisfactorily and we determine
that further development is warranted, we would file an IND application for the product with the FDA, and if the FDA gives its approval, we would begin Phase 1 clinical tests.
If Phase 1 test results are satisfactory and the FDA gives its approval, we can begin Phase 2 clinical tests. If Phase 2 test results are satisfactory and the FDA gives its approval,
we can begin Phase 3 pivotal studies. Once clinical testing is completed and a BLA or NDA is filed with the FDA, it may take more than a year to receive FDA approval.

The results of pre-clinical studies and early clinical trials may not be predictive of the results of later-stage clinical trials. We cannot assure you that the FDA will view the
results as we do or that any future trials of our drug candidates will achieve positive results. Product candidates in later stages of clinical trials may fail to show the desired
safety and efficacy traits despite having progressed through pre-clinical studies and initial clinical trials. A number of companies in the pharmaceutical industry have suffered
significant  setbacks  in  advanced  clinical  trials  due  to  lack  of  efficacy  or  adverse  safety  profiles,  notwithstanding  promising  results  in  earlier  trials. Any  future  clinical  trial
results for our drug candidates may not be successful.

In all cases, we must show that a drug candidate is both safe and effective before the FDA, or drug approval agencies of other countries where we intend to sell the product, will
approve it for sale. Our research and testing programs must comply with drug approval requirements both in the United States and in other countries, since we are developing
our drug candidates with the intention to, or could later decide to, commercialize them both in the U.S. and abroad. A product may fail for safety or effectiveness at any stage of
the testing process. A major risk we face is the possibility that none of our products under development will come through the testing process to final approval for sale, with the
result that we cannot derive any commercial revenue from them after investing significant amounts of capital in multiple stages of preclinical and clinical testing. In addition, a
number of factors could contribute to a lack of favorable safety and efficacy results for our drug candidates. For example, our trials could result in increased variability due to
varying  site  characteristics,  such  as  local  standards  of  care,  differences  in  evaluation  period  and  surgical  technique,  and  due  to  varying  patient  characteristics,  including
demographic factors and health status.

Even  if  we  receive  regulatory  approval  for  our  drug  candidates,  we  still  may  not  be  able  to  successfully  commercialize  any  of  our  products,  and  the  revenue  that  we
generate from sales, if any, may be limited.

If approved for marketing, the commercial success of our drug candidates will depend upon their acceptance by the medical community, including physicians, patients and
health care payors. The degree of market acceptance of our drug candidates will depend on a number of factors, including:

■ demonstration of clinical safety and efficacy;

■ relative convenience, pill burden and ease of administration;

■ the prevalence and severity of any adverse effects;

■ the willingness of physicians to prescribe our drug candidates and of the target patient population to try new therapies;

■ safety, tolerability and efficacy of our drug candidates compared to competing products;

■ the introduction of any new products that may in the future become available to treat indications for which our drug candidates may be approved;

■ new procedures or methods of treatment that may reduce the incidences of any of the indications in which our drug candidates may show utility;

■ pricing and cost-effectiveness;

■ the inclusion or omission of our drug candidates in applicable treatment guidelines;

■ the effectiveness of our or any future collaborators’ sales and marketing strategies;

■ limitations or warnings contained in FDA-approved labeling;

■ our ability to obtain and maintain sufficient third-party coverage or reimbursement from government health care programs, including Medicare and Medicaid, private

health insurers and other third-party payors; and

■ the willingness of patients to pay out-of-pocket in the absence of third-party coverage or reimbursement.

If any of our drug candidates are approved, but do not achieve an adequate level of acceptance by physicians, health care payors and patients, we may not generate sufficient
revenue and we may not be able to achieve or sustain profitability. Our efforts to educate the medical community and third-party payors on the benefits of our drug candidates
may require significant resources and may never be successful.

In addition, even if we obtain regulatory approvals, the timing or scope of any approvals may prohibit or reduce our ability to commercialize our drug candidates successfully.
For example, if the approval process takes too long, we may miss market opportunities and give other companies the ability to develop competing products or establish market
dominance.  Any  regulatory  approval  we  ultimately  obtain  may  be  limited  or  subject  to  restrictions  or  post-approval  commitments  that  render  our  drug  candidates  not
commercially viable. For example, regulatory authorities may approve our drug candidates for fewer or more limited indications than we request, may not approve the prices
we intend to charge for our drug candidates, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve our drug candidates with
labels that do not include the labeling claims necessary or desirable for the successful commercialization of a particular indication. Further, the FDA or comparable foreign
regulatory authorities may place conditions on approvals, such as risk management plans and a Risk Evaluation and Mitigation Strategy, or REMS, to assure the safe use of the
drug. If the FDA concludes a REMS is needed, the sponsor of the NDA must submit a proposed REMS; the FDA will not approve the NDA without an approved REMS, if
required. A REMS could include medication guides, physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries
and other risk minimization tools. The FDA may also require a REMS for an approved product when new safety information emerges. Any of these limitations on approval or
marketing could restrict the commercial promotion, distribution, prescription or dispensing of our drug candidates. Moreover, product approvals may be withdrawn for non-
compliance with regulatory standards or if problems occur following the initial marketing of the product. Any of the foregoing scenarios could materially harm the commercial
success of our drug candidates.

Even if we obtain marketing approval for our drug candidates, we will be subject to ongoing obligations and continued regulatory review, which may result in significant
additional expense. Additionally, our drug candidates could be subject to labeling and other restrictions and withdrawal from the market and we may be subject to penalties
if we fail to comply with regulatory requirements or if we experience unanticipated problems with our drug candidates.

Even  if  we  obtain  United  States  regulatory  approval  of  our  drug  candidates  for  an  indication,  the  FDA  may  still  impose  significant  restrictions  on  their  indicated  uses  or
marketing or the conditions of approval, or impose ongoing requirements for potentially costly and time-consuming post-approval studies, including Phase 4 clinical trials, and
post-market surveillance to monitor safety and efficacy. Our drug candidates will also be subject to ongoing regulatory requirements governing the manufacturing, labeling,
packaging,  storage,  distribution,  safety  surveillance,  advertising,  promotion,  recordkeeping  and  reporting  of  adverse  events  and  other  post-market  information.  These
requirements include registration with the FDA, continued compliance with current Good Clinical Practices regulations, or cGCPs, for any clinical trials that we conduct post-
approval, continued compliance with the CSA and ongoing review by the DEA. In addition, manufacturers of drug products and their facilities are subject to continual review
and periodic inspections by the FDA and other regulatory authorities for compliance with current Good Manufacturing Practices, or cGMP, requirements relating to quality
control, quality assurance and corresponding maintenance of records and documents.

With respect to sales and marketing activities by us or any future partner, advertising and promotional materials must comply with FDA rules in addition to other applicable
federal, state and local laws in the United States and similar legal requirements in other countries. In the United States, the distribution of product samples to physicians must
comply with the requirements of the U.S. Prescription Drug Marketing Act. Application holders must obtain FDA approval for product and manufacturing changes, depending
on the nature of the change. We may also be subject, directly or indirectly through our customers and partners, to various fraud and abuse laws, including, without limitation,
the U.S. Anti-Kickback Statute, U.S. False Claims Act, and similar state laws, which impact, among other things, our proposed sales, marketing, and scientific/educational
grant programs. If we participate in the U.S. Medicaid Drug Rebate Program, the Federal Supply Schedule of the U.S. Department of Veterans Affairs, or other government
drug  programs,  we  will  be  subject  to  complex  laws  and  regulations  regarding  reporting  and  payment  obligations.  All  of  these  activities  are  also  potentially  subject  to  U.S.
federal and state consumer protection and unfair competition laws. Similar requirements exist in many of these areas in other countries.

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

If we or a regulatory agency discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency or problems with the facility
where the product is manufactured, or if we or our manufacturers fail to comply with applicable regulatory requirements, we may be subject to the following administrative or
judicial sanctions:

■ restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, or voluntary or mandatory product recalls;

■ issuance of warning letters or untitled letters;

■ injunctions or the imposition of civil or criminal penalties or monetary fines;

■ suspension of any ongoing clinical trials;

■ refusal to approve pending applications or supplements to approved applications filed by us, or suspension or revocation of product license approvals;

■ suspension of, or imposition of restrictions on, operations, including costly new manufacturing requirements; or

■ product seizure or detention or refusal to permit the import or export of product.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our drug candidates and generate revenue. Adverse regulatory action, whether
pre- or post-approval, can also potentially lead to product liability claims and increase our product liability exposure.

The collaboration and license agreement, or the Collaboration Agreement, with Kaken Pharmaceuticals Co., Ltd., or Kaken, is important to our business. If we or Kaken
fail  to  adequately  perform  under  the  Collaboration  Agreement,  or  if  we  or  Kaken  terminate  the  Collaboration  Agreement,  the  development  and  commercialization  of
lenabasum for the treatment of SSc and DM in Japan would be delayed or terminated and our business would be adversely affected.

On  January  3,  2019,  we  entered  into  the  Collaboration  Agreement  with  Kaken,  pursuant  to  which  we  granted  to  Kaken  an  exclusive  license  to  commercialize  and  market
lenabasum  for  the  prevention  and  treatment  of  DM  and  SSc  in  Japan.  Our  ability  to  generate  revenue  under  the  Collaboration  Agreement  will  depend  in  large  part  on  our
success in further clinical development of lenabasum and Kaken’s success in achieving regulatory approval for, and commercializing lenabasum, in Japan. Such efforts are
subject to significant uncertainty. We have no control over the resources, time and effort that Kaken may devote to the commercialization of lenabasum. Any of several events
or factors could have a material adverse effect on our ability to generate revenue from Kaken’s commercialization of lenabasum in Japan. For example, Kaken:

■ may not achieve satisfactory levels of market acceptance and reimbursement by physicians, patients and third-party payers for lenabasum for the treatment of DM and

SSc;

■ may not compete successfully against other products and therapies for DM and SSc;

■ may have to comply with additional requests and recommendations from foreign regulatory authorities;

■ may not make all regulatory filings and obtain all necessary approvals from foreign regulatory agencies and all commercially necessary reimbursement approvals;

■ may not  commit  sufficient  resources  to  the  marketing  and  distribution  of  lenabasum,  whether  for  competitive  or  strategic  reasons  or otherwise due to a change in

business priorities; and

■ may cease to perform its obligations under the terms of the Collaboration Agreement.

In addition, pursuant to the Collaboration Agreement, we and Kaken have agreed to negotiate in good faith to enter into a supply agreement and a quality agreement. There can
be no assurance that we will be able to reach mutually agreeable terms on such agreements with Kaken, and the absence of agreement on such terms would prevent us from
gaining the expected benefit of the Collaboration Agreement.

Further,  we  and  Kaken  agreed  to  provide  mutual  indemnification  against  losses  in  connection  with  third-party  claims  arising  out  of  breaches  of  or  inaccuracies  in  the
Collaboration Agreement, gross negligence or willful misconduct, and the development or commercialization of lenabasum pursuant to the Collaboration Agreement. Conflicts
may arise in connection with these indemnification obligations.

After a specified period of time, Kaken may unilaterally terminate the Collaboration Agreement on 180 days’ prior written notice without any reason and without any further
commitment.  Kaken  may  also  terminate  in  the  event  of  certain  safety  concerns  and  clinical  failures,  and  either  we  or  Kaken  may  terminate  in  the  case  of  the  other  party’s
material breach or insolvency. Termination of the Collaboration Agreement could cause significant delays in our product candidate development and commercialization efforts,
which could prevent us from commercializing lenabasum without first expanding our internal capabilities or entering into another agreement with a third party. Any suitable
alternative collaboration or license agreement would take considerable time to negotiate and could also be on less favorable terms to us.

We  have  entered  into,  and  may  in  the  future  enter  into,  collaboration  agreements  for  the  licensing,  development  and  ultimate  commercialization  of  some  of  our  drug
candidates. In such cases, we will depend greatly on our third-party collaborators to license, develop and commercialize such drug candidates, and they may not meet our
expectations.

We  may  enter  into  further  co-development  and  commercialization  partnerships  for  our  drug  candidates  where  appropriate.  The  process  of  identifying  collaborators  and
negotiating collaboration agreements for the licensing, development and ultimate commercialization of some of our drug candidates may cause delays and increased costs. We
may not be able to enter into collaboration agreements on terms favorable to us or at all. Furthermore, some of those agreements may give substantial responsibility over our
drug candidates to the collaborator. Some collaborators may be unable or unwilling to devote sufficient resources to develop our drug candidates as their agreements require.
They often face business risks similar to ours, and this could interfere with their efforts. Also, collaborators may choose to devote their resources to products that compete with
ours.  If  a  collaborator  does  not  successfully  develop  any  one  of  our  products,  we  will  need  to  find  another  collaborator  to  do  so.  The  success  of  our  search  for  a  new
collaborator will depend on our legal right to do so at the time and whether the product remains commercially viable.

If we enter into collaboration agreements for one or more of our drug candidates, the success of such drug candidates will depend in great part upon our and our collaborators’
success in promoting them as superior to other treatment alternatives. We believe that our drug candidates can be proven to offer disease treatment with notable advantages over
drugs  in  terms  of  patient  compliance  and  effectiveness.  However,  there  can  be  no  assurance  that  we  will  be  able  to  prove  these  advantages  or  that  the  advantages  will  be
sufficient to support the successful commercialization of our drug candidates.

We  currently  have  a  limited  sales  and  marketing  organization.  If  we  are  unable  to  secure  a  sales  and  marketing  partner  or  establish  satisfactory  sales  and  marketing
capabilities, we may not successfully commercialize our drug candidates.

At present, we have a team of three employees in the commercial organization in order to commercialize products that are approved for commercial sales in the United States.
We  must  either  collaborate  with  third  parties  that  have  such  commercial  infrastructure  or  continue  to  develop  our  own  sales  and  marketing  infrastructure.  If  we  are  not
successful in entering into appropriate collaboration arrangements, or recruiting sales and marketing personnel or in building a sales and marketing infrastructure, we will have
difficulty successfully commercializing our drug candidates, which would adversely affect our business, operating results and financial condition.

We may not be able to enter into collaboration agreements on terms acceptable to us or at all. In addition, even if we enter into such relationships, we may have limited or no
control over the sales, marketing and distribution activities of these third parties. Our future revenues may depend heavily on the success of the efforts of these third parties. If
we elect to establish a sales and marketing infrastructure we may not realize a positive return on this investment. In addition, we will have to compete with established and
well-funded pharmaceutical and biotechnology companies to recruit, hire, train and retain sales and marketing personnel. Factors that may inhibit our efforts to commercialize
our drug candidates without strategic partners or licensees include:

■ our inability to recruit and retain adequate numbers of effective sales and marketing personnel;

■ the inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe our drug candidates;

■ the lack  of  complementary  products  to  be  offered  by  sales  personnel,  which  may  put  us  at  a  competitive  disadvantage  relative  to  companies with more extensive

product lines; and

■ unforeseen costs and expenses associated with creating an independent sales and marketing organization.

We face competition from other biotechnology and pharmaceutical companies and our operating results will suffer if we fail to compete effectively.

The  biotechnology  and  pharmaceutical  industries  are  intensely  competitive  and  subject  to  rapid  and  significant  technological  change. We  have  competitors  in  a  number  of
jurisdictions, many of which have substantially greater name recognition, commercial infrastructures and financial, technical and personnel resources than we have. Established
competitors  may  invest  heavily  to  quickly  discover  and  develop  novel  compounds  that  could  make  our  drug  candidates  obsolete  or  uneconomical.  Any  new  product  that
competes with an approved product may need to demonstrate compelling advantages in efficacy, cost, convenience, tolerability and safety to be commercially successful. Other
competitive factors, including generic competition, could force us to lower prices or could result in reduced sales. In addition, new products developed by others could emerge
as  competitors  to  our  drug  candidates.  If  we  are  not  able  to  compete  effectively  against  our  current  and  future  competitors,  our  business  will  not  grow  and  our  financial
condition and operations will suffer.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our drug candidates and affect the
prices we may obtain.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that
could  prevent  or  delay  marketing  approval  for  our  drug  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to  profitably  sell  our  drug  candidates.
Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. We do not
know whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes
on the marketing approvals of our drug candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay
or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

In  the  United  States,  under  the  Medicare  Modernization  Act,  or  MMA,  Medicare  Part  D  provides  coverage  to  the  elderly  and  disabled  for  outpatient  prescription  drugs  by
approving and subsidizing prescription drug plans offered by private insurers. The MMA also authorizes Medicare Part D prescription drug plans to use formularies where they
can limit the number of drugs that will be covered in any therapeutic class. The Part D plans use their formulary leverage to negotiate rebates and other price concessions from
drug manufacturers. Also under the MMA, Medicare Part B provides coverage to the elderly and disabled for physician-administered drugs on the basis of the drug’s average
sales price, a price that is calculated according to regulatory requirements and that the manufacturer reports to Medicare quarterly.

Both  Congress  and  the  Centers  for  Medicare  &  Medicaid  Services  (CMS),  the  agency  that  administers  the  Medicare  program,  from  time  to  time  consider  legislation,
regulations,  or  other  initiatives  to  reduce  drug  costs  under  Medicare  Parts  B  and  D.  For  example,  under  the  2010  Affordable  Care  Act,  drug  manufacturers  are  required  to
provide a 50% discount on prescriptions for branded drugs filled while the beneficiary is in the Medicare Part D coverage gap, also known as the “donut hole.” There have been
legislative proposals to repeal the “non-interference” provision of the MMA to allow CMS to leverage the Medicare market share to negotiate larger Part D rebates. Further cost
reduction efforts could decrease the coverage and price that we receive for our drug candidates and could seriously harm our business. Private payors often follow Medicare
coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in reimbursement under the Medicare program may result in a similar
reduction in payments from private payors.

The 2010 Affordable Care Act is intended to broaden access to health insurance and reduce or constrain the growth of healthcare spending. Further, the Affordable Care Act
imposes a significant annual fee on companies that manufacture or import branded prescription drug products. It also increased the amount of the rebates drug manufacturers
must pay to state Medicaid programs, required that Medicaid rebates be paid on managed Medicaid utilization, and increased the additional rebate on “line extensions” (such as
extended  release  formulations)  of  solid  oral  dosage  forms  of  branded  products.  The  law  also  contains  substantial  provisions  affecting  fraud  and  abuse  compliance  and
transparency, which may require us to modify our business practices with healthcare practitioners, and incur substantial costs to ensure compliance.

31

 
 
 
 
 
 
 
In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For example, the Budget Control Act of 2011 included,
among other things, provisions that have led to 2% across-the-board reductions in Medicare payment amounts. Several states have adopted or are considering adopting laws
that  require  pharmaceutical  companies  to  provide  notice  prior  to  raising  prices  and  to  justify  price  increases.  We  expect  that  additional  healthcare  reform  measures  will  be
adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, and in turn could significantly
reduce the projected value of certain development projects and reduce our profitability.

Our  future  growth  depends,  in  part,  on  our  ability  to  enter  into  and  succeed  in  markets  outside  of  the  United  States,  where  we  may  choose  to  rely  on  third  party
collaborations and will be subject to additional regulatory and commercial burdens, risks and other uncertainties.

Our future profitability will depend, in part, on our ability to gain approval of and commercialize our drug candidates in non-U.S. markets. In some or all of these non-U.S.
markets, we intend to enter into licensing and contractual collaborations with third parties, such as Kaken, to handle some or all of the tasks and responsibilities necessary to
succeed. Our activities in non-U.S. markets are subject to additional risks and uncertainties, including:

■ our ability to enter into favorable licensing and contractual arrangements with our partners;

■ our ability to select partners who are capable of achieving success at the tasks they agree to perform;

■ obtaining timely and sufficient favorable approval terms for our drug candidates;

■ obtaining favorable pricing and reimbursement;

■ our inability to directly control commercial activities because we are relying on third parties;

■ the burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements;

■ different medical practices and customs in foreign countries affecting acceptance in the marketplace;

■ import or export licensing requirements;

■ longer accounts receivable collection times;

■ longer lead times for shipping;

■ language barriers for technical training;

■ reduced protection of intellectual property rights in some foreign countries;

■ foreign currency exchange rate fluctuations; and

■ the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute.

International sales of our drug candidates could also be adversely affected by the imposition of governmental controls, political and economic instability, and trade restrictions
and changes in tariffs, any of which may adversely affect our results of operations.

If we market our drug candidates in a manner that violates healthcare fraud and abuse laws, or if we violate government price reporting laws, we may be subject to civil or
criminal penalties.

The FDA enforces laws and regulations which require that the promotion of pharmaceutical products be consistent with the approved prescribing information. While physicians
may prescribe an approved product for a so-called “off label” use, it is unlawful for a pharmaceutical company to promote its products in a manner that is inconsistent with its
approved  label  and  any  company  which  engages  in  such  conduct  may  be  subject  to  significant  liability.  Similarly,  industry  codes  in  the  European  Union  and  other  foreign
jurisdictions prohibit companies from engaging in off-label promotion and regulatory agencies in various countries enforce violations of the code with civil penalties. While we
intend to ensure that our promotional materials are consistent with our label, regulatory agencies may disagree with our assessment and may issue untitled letters, warning
letters or may institute other civil or criminal enforcement proceedings. In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state
and federal healthcare fraud and abuse laws have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. These laws include the U.S.
Anti-Kickback Statute, U.S. False Claims Act and similar state laws. Because of the breadth of these laws and the narrowness of the safe harbors, it is possible that some of our
business activities could be subject to challenge under one or more of these laws.

The  U.S.  Anti-Kickback  Statute  prohibits,  among  other  things,  knowingly  and  willfully  offering,  paying,  soliciting  or  receiving  remuneration  to  induce,  or  in  return  for,
purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other federally financed
healthcare programs. This statute has been interpreted broadly to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers and
formulary  managers  on  the  other.  Although  there  are  several  statutory  exemptions  and  regulatory  safe  harbors  protecting  certain  common  activities  from  prosecution,  the
exemptions  and  safe  harbors  are  drawn  narrowly,  and  practices  that  involve  remuneration  intended  to  induce  prescribing,  purchasing  or  recommending  may  be  subject  to
scrutiny if they do not qualify for an exemption or safe harbor. Our practices may not, in all cases, meet all of the criteria for safe harbor protection from anti-kickback liability.
Moreover, recent health care reform legislation has strengthened these laws. For example, the Health Care Reform Law, among other things, amends the intent requirement of
the U.S. Anti-Kickback Statute and criminal health care fraud statutes; a person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it.
In addition, the Health Care Reform Law provides that the government may assert that a claim including items or services resulting from a violation of the U.S. Anti-Kickback
Statute constitutes a false or fraudulent claim for purposes of the U.S. False Claims Act. Federal false claims laws prohibit any person from knowingly presenting, or causing to
be presented, a false claim for payment to the federal government or knowingly making, or causing to be made, a false statement to get a false claim paid.

Over the past few years, pharmaceutical and other healthcare companies have been prosecuted under these laws for a variety of alleged promotional and marketing activities,
such as: allegedly providing free trips, free goods, sham consulting fees and grants and other monetary benefits to prescribers; reporting to pricing services inflated average
wholesale  prices  that  were  then  used  by  federal  programs  to  set  reimbursement  rates;  engaging  in  off-label  promotion  that  caused  claims  to  be  submitted  to  Medicare  or
Medicaid for non-covered, off-label uses; and submitting inflated best price information to the Medicaid Rebate Program to reduce liability for Medicaid rebates. Most states
also have statutes or regulations similar to the U.S. Anti-Kickback Statute and the U.S. False Claims Act, which apply to items and services reimbursed under Medicaid and
other state programs, or, in several states, apply regardless of the payor. Sanctions under these federal and state laws may include substantial civil monetary penalties, exclusion
of a manufacturer’s products from reimbursement under government programs, substantial criminal fines and imprisonment.

We are, and will be, completely dependent on third parties to manufacture our drug candidates, and our commercialization of our drug candidates could be halted, delayed
or  made  less  profitable  if  those  third  parties  fail  to  obtain  manufacturing  approval  from  the  FDA  or  comparable  foreign  regulatory  authorities,  fail  to  provide  us  with
sufficient quantities of our drug candidates or fail to do so at acceptable quality levels or prices.

We do not currently have, nor do we plan to acquire, the capability or infrastructure to manufacture the active pharmaceutical ingredients of our drug candidates, or the finished
drug products, for use in our clinical trials or for commercial product, if any. As a result, we will be obligated to rely on contract manufacturers if and when our drug candidates
are approved for commercialization.

33

 
 
 
 
 
 
 
 
We currently rely on a single foreign supplier for manufacturing the starting chemical intermediates and finished bulk drug product for lenabasum. We also rely on a single
foreign supplier for the manufacturing of the finished lenabasum capsules. The facilities used by our two contract manufacturers to manufacture lenabasum must be approved
by  the  FDA  pursuant  to  inspections  that  will  be  conducted  after  we  submit  our  NDAs  to  the  FDA.  We  do  not  control  the  manufacturing  processes  of,  and  are  completely
dependent on, our two contract manufacturing partners for compliance with cGMPs for manufacture of all active drug substances and finished drug products. These cGMP
regulations cover all aspects of the manufacturing, testing, quality control and record keeping relating to our drug candidates. If our contract manufacturers cannot successfully
manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able to secure and/or maintain regulatory
approval for their manufacturing facilities. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of lenabasum or our
other product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our
ability to develop, obtain regulatory approval for or market our drug candidates, if approved.

Our contract manufacturers will be subject to ongoing periodic unannounced inspections by the FDA and corresponding state and foreign agencies for compliance with cGMPs
and similar regulatory requirements. We will not have control over our contract manufacturers’ compliance with these regulations and standards. Failure by any of our contract
manufacturers  to  comply  with  applicable  regulations  could  result  in  sanctions  being  imposed  on  us,  including  fines,  injunctions,  civil  penalties,  failure  to  grant  approval  to
market our drug candidates, delays, suspensions or withdrawals of approvals, operating restrictions and criminal prosecutions, any of which could significantly and adversely
affect our business. In addition, we will not have control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified
personnel. Failure by our contract manufacturers to comply with or maintain any of these standards could adversely affect our ability to develop, obtain regulatory approval for
or market our drug candidates.

If for any reason, these third parties are unable or unwilling to perform, we may not be able to terminate our agreements with them, and we may not be able to locate alternative
manufacturers or formulators or enter into favorable agreements with them and we cannot be certain that any such third parties will have the manufacturing capacity to meet
future  requirements.  If  these  manufacturers  or  any  alternate  manufacturer  of  finished  drug  product  experiences  any  significant  difficulties  in  its  respective  manufacturing
processes for our active pharmaceutical ingredient, or API, or our finished products or should cease doing business with us, we could experience significant interruptions in the
supply of our drug candidates or may not be able to create a supply of our drug candidates at all. Were we to encounter manufacturing issues, our ability to produce a sufficient
supply of our drug candidates might be negatively affected. Our inability to coordinate the efforts of our third party manufacturing partners, or the lack of capacity available at
our third party manufacturing partners, could impair our ability to supply our drug candidates at required levels. Because of the significant regulatory requirements that we
would need to satisfy in order to qualify a new bulk or finished product manufacturer, if we face these or other difficulties with our current manufacturing partners, we could
experience  significant  interruptions  in  the  supply  of  our  drug  candidates  if  we  decided  to  transfer  the  manufacture  of  our  drug  candidates  to  one  or  more  alternative
manufacturers in an effort to deal with the difficulties.

Any manufacturing problem or the loss of a contract manufacturer could be disruptive to our operations and result in lost sales. Additionally, we rely on third parties to supply
the raw materials needed to manufacture our potential products. Any reliance on suppliers may involve several risks, including a potential inability to obtain critical materials
and reduced control over production costs, delivery schedules, reliability and quality. Any unanticipated disruption to a future contract manufacturer caused by problems at
suppliers could delay shipment of our drug candidates, increase our cost of goods sold and result in lost sales.

We  cannot  guarantee  that  our  manufacturing  and  supply  partners  will  be  able  to  manufacture  our  drug  candidates  at  commercial  scale  on  a  cost-effective  basis.  If  the
commercial-scale manufacturing costs of our drug candidates are higher than expected, these costs may significantly impact our operating results. In order to reduce costs, we
may  need  to  develop  and  implement  process  improvements.  However,  in  order  to  do  so,  we  will  need,  from  time  to  time,  to  notify  or  make  submissions  with  regulatory
authorities, and the improvements may be subject to approval by such regulatory authorities. We cannot be sure that we will receive these necessary approvals or that these
approvals will be granted in a timely fashion. We also cannot guarantee that we will be able to enhance and optimize output in our commercial manufacturing process. If we
cannot enhance and optimize output, we may not be able to reduce our costs over time.

34

 
 
 
 
 
 
 
There  are  risks  associated  with  scaling  up  manufacturing  to  commercial  scale.  If  our  contract  manufacturers  are  unable  to  manufacture  our  drug  candidates  on  a
commercial scale, this could potentially delay regulatory approval and commercialization or materially adversely affect our results of operations.

There are risks associated with scaling up manufacturing to commercial volumes including, among others, cost overruns, technical problems with process scale-up, process
reproducibility, stability issues, and lot consistency. Even if we obtain regulatory approval for our drug candidates, there is no assurance that our contract manufacturers will be
able  to  manufacture  the  approved  products  to  specifications  acceptable  to  the  FDA  or  other  regulatory  authorities,  to  produce  them  in  sufficient  quantities  to  meet  the
requirements for the potential launch of the product or to meet potential future demand. If our manufacturers are unable to produce sufficient quantities of approved products
for commercialization, either on a timely basis or at all, our commercialization efforts would be impaired, which would have a material adverse effect on our business, financial
condition, results of operations and growth prospects.

Our lead product candidate, lenabasum, is currently classified as a Schedule I controlled substance subject to U.S. controlled substance laws and regulations, including
regulations of the Drug Enforcement Agency and the U.S. Food and Drug Administration. Failure to obtain the necessary licenses and registrations and failure to comply
with these laws could result in the delay in the manufacturing and distribution of lenabasum and could delay the completion of clinical studies. Such delays and the cost of
compliance with these laws and regulations, could adversely affect our business operations and our financial condition.

In the United States, our lead product candidate, lenabasum, is currently classified as a Schedule I controlled substance as defined in the Controlled Substance Act, or CSA.
This  designation  is  mainly  based  on  lenabasum’s  chemical  structure  (it  is  a  synthetic  compound  that  is  structurally  related  to  the  non-psychoactive  terminal  metabolite  of
tetrahydrocannabinol).

Schedule  I  controlled  substances  are  pharmaceutical  products  subject  to  specific  regulations  under  the  CSA,  which  establishes,  among  other  things,  certain  registration,
manufacturing  quotas,  security,  recordkeeping,  reporting,  import,  export  and  other  requirements  administered  by  the  DEA.  All  parties  responsible  for  the  manufacturing,
distribution and testing of the drug in clinical studies must apply for and obtain a license from the DEA before they are permitted to perform these activities with lenabasum.
Furthermore, these parties must have the security, control, recordkeeping, reporting and inventory mechanisms required by the DEA to prevent drug loss and diversion. All
licensed  facilities  are  required  to  renew  their  registrations  annually  if  they  intend  to  continue  to  work  with  our  drug.  The  DEA  conducts  periodic  inspections  of  certain
registered  establishments  that  handle  controlled  substances. We  have  been  working  with  our  manufacturers,  distributors,  exporters  and  clinical  sites  to  obtain  the  necessary
licenses to work with lenabasum. The parties responsible for the manufacturing, distribution and export of lenabasum have already applied for and have been granted DEA
licenses  and  a  number  of  institutions  responsible  for  conducting  our  current  clinical  studies  have  also  been  granted  DEA  licenses.  However,  the  failure  to  maintain  the
necessary registrations, and the delay or failure of additional clinical sites to obtain DEA registrations, could delay the manufacturing, distribution and export of lenabasum and
could delay the completion of the clinical studies. Furthermore, failure to maintain compliance with the CSA, particularly non-compliance resulting in loss or diversion, could
result in regulatory action that could have a material adverse effect on our business, financial condition and results of operations. The DEA may seek civil penalties, refuse to
renew necessary registrations, or initiate proceedings to restrict, suspend or revoke those registrations. In certain circumstances, violations could lead to criminal proceedings.
In addition, if the FDA, DEA, or any foreign regulatory authority determines that lenabasum may have potential for abuse, it may require us to generate more clinical or other
data  than  we  currently  anticipate  to  establish  whether  or  to  what  extent  the  substance  has  an  abuse  potential,  which  could  increase  the  cost  and/or  delay  the  launch  of
lenabasum.

Individual  states  have  also  established  controlled  substance  laws  and  regulations.  Though  state-controlled  substances  laws  often  mirror  federal  law,  because  the  states  are
separate jurisdictions, they may separately schedule drugs, as well. While some states automatically schedule a drug based on federal action, other states schedule drugs through
rulemaking or a legislative action. The requirement for state registrations could also result in delay of the manufacturing and distribution of lenabasum or in the completion of
our clinical studies. We and our manufacturing vendors and clinical sites must also obtain separate state registrations, permits or licenses in order to be able to obtain, handle
and distribute controlled substances for clinical trials or commercial sale, and failure to meet applicable regulatory requirements could lead to enforcement and sanctions by the
states in addition to those from the DEA or otherwise arising under federal law.

35

 
 
 
 
 
 
 
 
The manufacturing and distribution of lenabasum is subject to the DEA’s annual manufacturing and procurement quota requirements. The annual quota allocated to us or our
contract  manufacturers  for  the  controlled  substances  in  lenabasum  may  not  be  sufficient  to  complete  clinical  trials.  Consequently,  any  delay  or  refusal  by  the  DEA  in
establishing  our,  or  our  contract  manufacturers’,  procurement  and/or  production  quota  for  controlled  substances  could  delay  or  stop  our  clinical  trials  or  product  launches,
which could have a material adverse effect on our business, financial position and operations.

While lenabasum is a Schedule I controlled substance, if lenabasum is approved for medical use by the FDA, it will have satisfied the “accepted medical use” requirement of
the CSA. If and when lenabasum receives FDA approval, the DEA will make a scheduling determination and place lenabasum in a schedule other than Schedule I or declassify
it in order for it to be prescribed to patients in the United States. As part of the scheduling determination, FDA will assess the abuse and dependence potential of lenabasum and
make  a  scheduling  recommendation  to  DEA.  If  approved  by  the  FDA,  the  length  of  time  the  DEA  takes  to  complete  the  rescheduling  or  declassification  of  lenabasum  is
uncertain and could be lengthy and we will not be able to sell the drug until the rescheduling is complete. Any delays in the rescheduling could have a material adverse impact
on our results of operations.

Delays in shipping our drug candidates could have a material adverse effect on our business, results of operations and financial condition.

The import and export of our drug candidates requires import and export licenses. In addition, because lenabasum is currently a Schedule I controlled substance in the United
States, in addition to the FDA and U.S. Customs and Border Protection, its import and export is also regulated by the DEA. We may not be granted, or if granted, maintain,
such licenses for import or export from the authorities these regulatory agencies. Even if we obtain the relevant licenses, shipments of our drug candidates may be held up in
transit  by  any  of  these  authorities,  which  could  cause  significant  delays  and  may  lead  to  product  batches  which  no  longer  meet  specifications  for  use  in  clinical  trials  or
commercial distribution. Such events could result in delayed development timelines, increased expenses and partial or total loss of revenue from our drug candidates.

We  expect  that  we  will  rely  on  third  parties  to  assist  us  in  conducting  clinical  trials  for  our  drug  candidates.  If  these  third  parties  do  not  successfully  carry  out  their
contractual  duties  or  meet  expected  deadlines,  we  may  not  be  able  to  obtain  regulatory  approval  for  or  commercialize  our  drug  candidates  and  our  business  would  be
substantially harmed.

We expect to enter into agreements with third-party CROs to assist us in conducting and managing our clinical programs, including contracting with clinical sites to perform
our clinical studies. We plan to rely on these parties for execution of clinical studies for our drug candidates and we will control only certain aspects of conducting the clinical
studies.  Nevertheless,  we  will  be  responsible  for  ensuring  that  each  of  our  studies  is  conducted  in  accordance  with  the  applicable  protocol,  legal,  regulatory  and  scientific
standards, and our reliance on CROs and clinical sites will not relieve us of our regulatory responsibilities. We and our CROs will be required to comply with cGCPs, which are
regulations  and  guidelines  enforced  by  the  FDA,  the  Competent  Authorities  of  the  Member  States  of  the  European  Economic  Area  and  comparable  foreign  regulatory
authorities for any products in clinical development. The FDA enforces these cGCP regulations through periodic inspections of trial sponsors, principal investigators and trial
sites. If we or our CROs fail to comply with applicable cGCPs, 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, the FDA
will determine that any of our clinical trials comply with cGCPs. In addition, our clinical trials must be conducted with products produced under cGMP regulations and will
require a large number of test subjects. Our failure or the failure of our CROs or clinical sites to comply with these regulations may require us to repeat clinical trials, which
would delay the regulatory approval process and could also subject us to enforcement action up to and including civil and criminal penalties.

36

 
 
 
 
 
 
 
 
Although we intend to design the clinical trials for our drug candidates in consultation with CROs, we expect that the CROs will manage and assist us with the clinical trials
conducted at contracted clinical sites. As a result, many important aspects of our drug development programs would be outside of our direct control. In addition, the CROs and
clinical sites may not perform all of their obligations under arrangements with us or in compliance with regulatory requirements. If the CROs or clinical sites do not perform
clinical trials in a satisfactory manner, or if they breach their obligations to us or fail to comply with regulatory requirements, the development and commercialization of our
drug  candidates  for  the  subject  indications  may  be  delayed  or  our  development  program  materially  and  irreversibly  harmed.  We  cannot  control  the  amount  and  timing  of
resources these CROs and clinical sites will devote to our program or our drug candidates. If we are unable to rely on clinical data collected by our CROs, we could be required
to repeat, extend the duration of, or increase the size of our clinical trials, which could significantly delay commercialization and require significantly greater expenditures.

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

Any  termination  or  suspension  of  or  delays  in  the  commencement  or  completion  of  any  necessary  studies  of  our  drug  candidates  for  any  indications  could  result  in
increased costs to us, delay or limit our ability to generate revenue and adversely affect our commercial prospects.

The commencement and completion of clinical studies can be delayed for a number of reasons, including delays related to:

■ the FDA failing to grant permission to proceed and placing the clinical study on hold;

■ subjects failing to enroll or remain in our trials at the rate we expect;

■ a facility manufacturing any of our drug candidates being ordered by the FDA or other government or regulatory authorities to temporarily or permanently shut down

due to violations of cGMP requirements or other applicable requirements, or cross-contaminations of product in the manufacturing process;

■ any changes to our manufacturing process that may be necessary or desired;

■ subjects choosing an alternative treatment for the indications for which we are developing our drug candidates, or participating in competing clinical studies;

■ subjects experiencing severe or unexpected drug-related adverse effects;

■ reports of similar technologies and products raising safety and/or efficacy concerns;

■ third-party clinical investigators losing their license or permits necessary to perform our clinical trials, not performing our clinical trials on our anticipated schedule or
employing  methods  consistent  with  the  clinical  trial  protocol,  cGCP  requirements,  or  other  third  parties  not  performing  data  collection  and  analysis  in  a  timely  or
accurate manner;

■ inspections of clinical study sites by the FDA or IRBs finding regulatory violations that require us to undertake corrective action, result in suspension or termination of
one or more sites or the imposition of a clinical hold on the entire study, or that prohibit us from using some or all of the data in support of our marketing applications;

■ third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for violations of regulatory
requirements,  in  which  case  we  may  need  to  find  a  substitute  contractor,  and  we  may  not  be  able  to  use  some  or  any  of  the  data  produced  by  such  contractors  in
support of our marketing applications;

37

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
■ one or more IRBs refusing to approve, suspending or terminating the study at an investigational site precluding enrollment of additional subjects, or withdrawing its
approval of the trial; reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject to extensive negotiation
and may vary significantly among different CROs and trial sites;

■ deviations of the clinical sites from trial protocols or dropping out of a trial;

■ adding new clinical trial sites;

■ the inability of the CRO to execute any clinical trials for any reason;

■ government or regulatory delays or “clinical holds” requiring suspension or termination of a trial; and

■ delays related to the impacts of COVID-19, including slowdowns in enrollment or our ability complete our clinical trials on our expected timeline.

Product development costs for our drug candidates will increase if we have delays in testing or approval or if we need to perform more or larger clinical studies than planned.
Additionally, changes in regulatory requirements and policies may occur and we may need to amend study protocols to reflect these changes. Amendments may require us to
resubmit our study protocols to the FDA and IRBs for reexamination, which may impact the costs, timing or successful completion of that study. If we experience delays in
completion of, or if we, the FDA or other regulatory authorities, any IRBs, or other reviewing entities, or any of our clinical study sites suspend or terminate any of our clinical
studies of our drug candidates, our commercial prospects may be materially harmed and our ability to generate product revenues will be delayed. Any delays in completing our
clinical trials will increase our costs, slow down our 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, termination or suspension of, or
a delay in the commencement or completion of, clinical studies may also ultimately lead to the denial of regulatory approval of our drug candidates. In addition, if one or more
clinical studies are delayed, our competitors may be able to bring products to market before we do, and the commercial viability of our drug candidates could be significantly
reduced.

We may not be able to obtain or maintain orphan drug designation or exclusivity for our product candidates.

We have been granted orphan drug designation in the United States and in the European Union for lenabasum for the treatment of CF, SSc and DM. Upon receipt of regulatory
approval, orphan drug status will provide us with seven years of market exclusivity in the United States under the Orphan Drug Act. However, there is no guarantee that the
FDA  will  grant  orphan  drug  designation  for  any  of  our  drug  candidates  for  any  future  indication,  which  would  make  us  ineligible  for  the  additional  exclusivity  and  other
benefits of orphan drug designation. Moreover, there can be no assurance that another company also holding orphan drug designation for the same indication or which may
receive orphan drug designation in the future will not receive approval prior to us, in which case our competitor would have the benefit of the seven years of market exclusivity,
and we would be unable to commercialize our product for the same indication until the expiration of such seven-year period. Even if we are the first to obtain approval for the
orphan drug indication, there are circumstances under which a competing product may be approved for the same indication during our seven-year period of exclusivity.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to a drug intended to treat a rare disease or condition, which is generally a disease or condition that
affects fewer than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making a drug available in the
Unites States for this type of disease or condition will be recovered from sales of the product. Orphan drug designation must be requested before submitting an NDA. After the
FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan designation does not convey
any advantage in or shorten the duration of regulatory review and approval process. In addition to the potential period of exclusivity, orphan designation makes a company
eligible for grant funding of up to $400,000 per year for four years to defray costs of clinical trial expenses, tax credits for clinical research expenses and potential exemption
from the FDA application user fee.

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to
orphan drug exclusivity, which means the FDA may not approve any other applications to market the same drug for the same indication for seven years, except in limited
circumstances, such as (i) the drug’s orphan designation is revoked; (ii) its marketing approval is withdrawn; (iii) the orphan exclusivity holder consents to the approval of
another applicant’s product; (iv) the orphan exclusivity holder is unable to assure the availability of a sufficient quantity of drug; or (v) a showing of clinical superiority to the
product  with  orphan  exclusivity  by  a  competitor  product.  If  a  drug  designated  as  an  orphan  product  receives  marketing  approval  for  an  indication  broader  than  what  is
designated, it may not be entitled to orphan drug exclusivity. There can be no assurance that we will receive orphan drug designation for any of our drug candidates for any
additional indications, if we elect to seek such designation.

Any fast track designation or grant of priority review status by the FDA may not actually lead to a faster development or regulatory review or approval process, nor will it
assure FDA approval of our product candidates. Additionally, our product candidates may treat indications that do not qualify for priority review vouchers.

We have received fast track designation for lenabasum for the treatment of cystic fibrosis and systemic sclerosis in the United States and European Union and may seek fast
track  designation  or  priority  review  of  applications  for  approval  of  our  product  candidate  for  future  indications.  If  a  drug  is  intended  for  the  treatment  of  a  serious  or  life-
threatening condition and the drug demonstrates the potential to address unmet medical needs for this condition, the drug sponsor may apply for FDA fast track designation. If a
product  candidate  offers  major  advances  in  treatment,  the  FDA  may  designate  it  eligible  for  priority  review.  The  FDA  has  broad  discretion  whether  or  not  to  grant  these
designations, so even if we believe a particular product candidate is eligible for these designations, we cannot assure you that the FDA would decide to grant them. Even if we
do receive fast track designation or priority review, we may not experience a faster development process, review or approval compared to conventional FDA procedures. The
FDA may withdraw fast track designation if it believes that the designation is no longer supported by data from our clinical development program.

Any breakthrough therapy designation granted by the FDA for our product candidate may not lead to a faster development or regulatory review or approval process, and it
does not increase the likelihood that our product candidate will receive marketing approval.

We have applied for, and may in the future apply for, a breakthrough therapy designation of our product candidates for future indications. A breakthrough therapy is defined as
a  drug  that  is  intended,  alone  or  in  combination  with  one  or  more  other  drugs,  to  treat  a  serious  or  life-threatening  disease  or  condition,  and  preliminary  clinical  evidence
indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects
observed early in clinical development. For drugs and biologics that have been designated as breakthrough therapies, interaction and communication between the FDA and the
sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens. Drugs
designated as breakthrough therapies by the FDA may also be eligible for accelerated approval if the relevant criteria are met.

Designation of a product candidate as a breakthrough therapy is within the discretion of the FDA. Accordingly, even if we believe our product candidate meets the criteria for
designation  as  a  breakthrough  therapy,  the  FDA  may  disagree  and  instead  determine  not  to  make  such  designation.  In  any  event,  the  receipt  of  a  breakthrough  therapy
designation for a product candidate may not result in a faster development process, review or approval compared to drugs considered for approval under conventional FDA
procedures and does not assure ultimate approval by the FDA. In addition, even if one or more of our product candidates qualify as breakthrough therapies, the FDA may later
decide that the products no longer meet the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

39

 
 
 
 
 
 
 
 
Third-party coverage and reimbursement and health care cost containment initiatives and treatment guidelines may constrain our future revenues.

Our  ability  to  successfully  market  our  drug  candidates  will  depend  in  part  on  the  level  of  reimbursement  that  government  health  administration  authorities,  private  health
coverage insurers and other organizations provide for the cost of our products and related treatments. Countries in which our drug candidates are expected to be sold through
reimbursement schemes under national health insurance programs frequently require that manufacturers and sellers of pharmaceutical products obtain governmental approval of
initial  prices  and  any  subsequent  price  increases.  In  certain  countries,  including  the  United  States,  government-funded  and  private  medical  care  plans  can  exert  significant
indirect pressure on prices. We may not be able to sell our drug candidates profitably if adequate prices are not approved or coverage and reimbursement is unavailable or
limited in scope. Increasingly, third-party payors attempt to contain health care costs in ways that are likely to impact our development of products including:

■ failing to approve or challenging the prices charged for health care products;

■ introducing reimportation schemes from lower priced jurisdictions;

■ limiting both coverage and the amount of reimbursement for new therapeutic products;

■ denying or limiting coverage for products that are approved by the regulatory agencies but are considered to be experimental or investigational by third-party payors;

and

■ refusing to provide coverage when an approved product is used in a way that has not received regulatory marketing approval.

It is difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights.

Risks Relating to Our Intellectual Property Rights

Our commercial success will depend, in part, on maintaining and obtaining additional patent protection for our technologies, products and processes, successfully defending
these patents against third-party challenges and successfully enforcing these patents against third party competitors. The patent positions of pharmaceutical companies can be
highly uncertain and involve complex legal, scientific and factual questions for which important legal principles remain unresolved. Changes in either the patent laws or in
interpretations of patent laws may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be allowable in our pending
applications or, the enforceability of our existing and future patents. Our pending patent applications for lenabasum and its uses may never be approved by United States or
foreign patent offices and the existing patents and patent applications relating to lenabasum and related technologies may be challenged, invalidated or circumvented by third
parties and may not protect us against competitors with similar products or technologies.

The degree of our current and future protection for our proprietary rights is uncertain, because legal means afford only limited protection and may not adequately protect our
rights, permit us to gain or keep our competitive advantage, or provide us with any competitive advantage at all. For example, others have filed, and in the future are likely to
file, patent applications covering products and technologies that are similar, identical or competitive to lenabasum, or important to our business. We cannot be certain that any
patents  or  patent  application  owned  by  a  third  party  will  not  have  priority  over  patents  and  patent  applications  filed  by  us,  or  that  we  will  not  be  involved  in  interference,
opposition or invalidity proceedings before United States or foreign patent offices.

We also rely on trade secrets to protect technology, especially in cases when we believe patent protection is not appropriate or obtainable. However, trade secrets are difficult to
protect.  While  we  require  employees,  academic  collaborators,  consultants  and  other  contractors  to  enter  into  confidentiality  agreements,  we  may  not  be  able  to  adequately
protect our trade secrets or other proprietary or licensed information. Typically, research collaborators and scientific advisors have rights to publish data and information in
which we may have rights. If we cannot maintain the confidentiality of our proprietary technology and other confidential information, our ability to receive patent protection
and our ability to protect valuable information owned by us may be imperiled. Enforcing a claim that a third-party entity illegally obtained and is using any of our trade secrets
is  expensive  and  time  consuming,  and  the  outcome  is  unpredictable.  In  addition,  courts  are  sometimes  less  willing  to  protect  trade  secrets  than  patents.  Moreover,  our
competitors may independently develop equivalent knowledge, methods and know-how.

If we fail to maintain or obtain additional patent protection or trade secret protection for lenabasum or our technologies, third parties could use our proprietary information,
which could impair our ability to compete in the market and adversely affect our ability to generate revenues and attain profitability.

We may also rely on the trademarks we may develop to distinguish our products from the products of our competitors. We cannot guarantee that any trademark applications
filed by us or our business partners will be approved. Third parties may also oppose such trademark applications, or otherwise challenge our use of the trademarks. In the event
that the trademarks we use are successfully challenged, we could be forced to rebrand our products, which could result in loss of brand recognition, and could require us to
devote resources to advertising and marketing new brands. Further, we cannot provide assurance that competitors will not infringe the trademarks we use, or that we will have
adequate resources to enforce these trademarks.

We have in-licensed a portion of our intellectual property, and if we fail to comply with our obligations under these arrangements, we could lose such intellectual property
rights or owe damages to the licensor of such intellectual property.

We are a party to a license agreement with Jenrin pursuant to which we licensed the exclusive worldwide rights to develop, manufacture and market drug candidates from
Jenrin. This agreement is important to our business, and we may enter into additional license agreements in the future. Certain of our in-licensed intellectual property covers, or
may cover and potential cannabinoid developmental candidates. Our existing license agreement imposes, and we expect that future license agreements will impose, various
diligence,  milestone  payment,  royalty  and  other  obligations  on  us.  If  there  is  any  conflict,  dispute,  disagreement  or  issue  of  non-performance  between  us  and  our  licensing
partners  regarding  our  rights  or  obligations  under  the  license  agreements,  including  any  such  conflict,  dispute  or  disagreement  arising  from  our  failure  to  satisfy  payment
obligations under any such agreement, we may owe damages, our licensor may have a right to terminate the affected license, and our ability to utilize the affected intellectual
property  in  our  product  discovery  and  development  efforts  and  our  ability  to  enter  into  collaboration  or  marketing  agreements  for  an  affected  product  candidate  may  be
adversely affected.

Lenabasum and our other product candidates may infringe the intellectual property rights of others, which could increase our costs and delay or prevent our development
and commercialization efforts.

Our  success  depends  in  part  on  avoiding  infringement  of  the  proprietary  technologies  of  others.  The  pharmaceutical  industry  has  been  characterized  by  frequent  litigation
regarding patent and other intellectual property rights. Identification of third-party patent rights that may be relevant to our proprietary technology is difficult because patent
searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. Additionally, because
patent  applications  are  maintained  in  secrecy  until  the  application  is  published,  we  may  be  unaware  of  third-party  patents  that  may  be  infringed  by  commercialization  of
lenabasum or any of our other product candidates. There may be certain issued patents and patent applications claiming subject matter that we may be required to license in
order  to  research,  develop  or  commercialize  lenabasum  or  our  other  product  candidates,  and  we  do  not  know  if  such  patents  and  patent  applications  would  be  available  to
license on commercially reasonable terms, or at all. Any claims of patent infringement asserted by third parties would be time-consuming and may:

■ result in costly litigation;

■ divert the time and attention of our technical personnel and management;

■ prevent us from commercializing a product until the asserted patent expires or is held finally invalid or not infringed in a court of law;

■ require us to cease or modify our use of the technology and/or develop non-infringing technology; or

■ require us to enter into royalty or licensing agreements.

Although no third party has asserted a claim of infringement against us, others may hold proprietary rights that could prevent our product candidates from being marketed. Any
patent-related  legal  action  against  us  claiming  damages  and  seeking  to  enjoin  commercial  activities  relating  to  our  product  candidates  or  our  processes  could  subject  us  to
potential liability for damages and require us to obtain a license to continue to manufacture or market lenabasum or any other product candidates. We cannot predict whether we
would prevail in any such actions or that any license required under any of these patents would be made available on commercially acceptable terms, if at all. In addition, we
cannot be sure that we could redesign lenabasum or any other product candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a
judicial  or  administrative  proceeding,  or  the  failure  to  obtain  necessary  licenses,  could  prevent  us  from  developing  and  commercializing  lenabasum  or  another  product
candidate, which could harm our business, financial condition and operating results.

A number of companies, including several major pharmaceutical companies, have conducted research on anti-inflammatory and anti-fibrosis therapies which resulted in the
filing of many patent applications related to this research. If we were to challenge the validity of these or any issued United States patent in court, we would need to overcome a
statutory presumption of validity that attaches to every issued United States patent. This means that, in order to prevail, we would have to present clear and convincing evidence
as to the invalidity of the patent’s claims.

If we were to challenge the validity of these or any issued United States patent in an administrative trial before the Patent Trial and Appeal Board in the United States Patent
and Trademark Office, we would have to prove that the claims are unpatentable by a preponderance of the evidence. There is no assurance that a jury and/or court would find in
our favor on questions of infringement, validity or enforceability.

We  may  be  subject  to  claims  that  we  have  wrongfully  hired  an  employee  from  a  competitor  or  that  we  or  our  employees  have  wrongfully  used  or  disclosed  alleged
confidential information or trade secrets of their former employers.

As  is  commonplace  in  our  industry,  we  employ  individuals  who  were  previously  employed  at  other  pharmaceutical  companies,  including  our  competitors  or  potential
competitors.  Although  no  claims  against  us  are  currently  pending,  we  may  be  subject  in  the  future  to  claims  that  our  employees  or  prospective  employees  are  subject  to  a
continuing obligation to their former employers (such as non-competition or non-solicitation obligations) or claims that our employees or we have inadvertently or otherwise
used or disclosed trade secrets or other proprietary information of their former employers. 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.

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

Although we are not aware of any asserted third-party claims challenging inventorship on our patents or ownership of our intellectual property, we may in the future be subject
to claims that former employees, strategic partners, commercial counterparties or other third parties associated with us or one of our predecessors in ownership of lenabasum
have an interest in our patents or other intellectual property as an inventor or co-inventor. While it is our policy to require our employees and contractors who may be involved
in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we cannot fully control the enforcement of these
policies  by  third  parties  with  which  we  contract,  nor  can  we  be  certain  that  assignment  agreements  between  us  and  our  employees,  between  us  and  our  counterparties,  or
between our counterparties and their employees or between our predecessors of ownership and their employees and counterparties, will effectively protect our interests as to
any  party  who  conceives  or  develops  intellectual  property  that  we  regard  as  our  own.  Among  other  issues,  the  assignment  of  intellectual  property  rights  may  not  be  self-
executing, the assignment agreements may be breached, or we may have disputes arise from conflicting obligations of consultants or others who are involved in developing our
product candidates. As we approach potential commercialization of our product candidates, we are more closely analyzing all facts that we believe might be used to assert an
inventorship claim against us. Determinations like these involve complex sets of fact and applications of sometimes-unsettled patent law, resulting in inherent uncertainties
regarding  ownership  rights.  Determining  the  history  of  development  of  certain  of  our  intellectual  property  is  made  more  difficult  by  the  fact  that  certain  of  our  intellectual
property was developed by other companies for other indications before being acquired by us. Consequently, we cannot be sure that we have all of the documentary records
relevant to such an analysis. In the course of our analysis we identified a potential issue regarding incomplete inventorship on certain aspects of our lenabasum portfolio that
were  developed  prior  to  our  acquisition  of  lenabasum.  Since  identifying  this  potential  issue,  we  reached  agreement  with  the  relevant  third-party  co-inventors  and  received
assignments of such co-inventors’ rights in and to the relevant patents.

If claims challenging inventorship are made against us, we may need to resort to litigation to resolve those claims. If we fail in defending against any such claims, in addition to
paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of valuable intellectual property rights or the right to assert those
rights  against  third-parties  marketing  competing  products.  Even  if  we  are  successful  in  defending  against  such  claims,  litigation  could  result  in  substantial  costs  and  be  a
distraction to management and other employees.

There are risks to our Intellectual Property based on our international business operations.

We  may  face  risks  to  our  technology  and  intellectual  property  as  a  result  of  our  conducting  business  outside  of  the  United  States,  including  as  a  result  of  our  license  and
collaboration agreement with Kaken, and particularly in jurisdictions that do not have comparable levels of protection of corporate proprietary information and assets such as
intellectual property, trademarks, trade secrets, know-how and customer information and records. While these risks are common to many companies, conducting business in
certain  foreign  jurisdictions,  housing  technology,  data  and  intellectual  property  abroad,  or  licensing  technology  to  joint  ventures  with  foreign  partners  may  have  more
significant exposure. Pursuant to our license and collaboration agreement with Kaken, we have granted Kaken an exclusive license to commercialize lenabasum in Japan, and
an  exclusive,  worldwide  license  for  the  development  and  manufacturing  of  lenabasum  in  connection  with  Kaken’s  commercialization  efforts.  As  a  result,  and  in  the  event
Kaken partners with other companies in other foreign jurisdictions in connection with the development and manufacturing of lenabasum, we may be exposed to material risks
of theft of our proprietary information and other intellectual property, including technical data, manufacturing processes, data sets or other sensitive information. For example,
our products or components may be reverse engineered by other business partners or other parties, which could result in our patents being infringed or our know-how or trade
secrets stolen. The risk can be by direct intrusion wherein technology and intellectual property is stolen or compromised through cyber intrusions or physical theft through
corporate espionage, including with the assistance of insiders, or via more indirect routes.

General Company-Related Risks

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of December 31, 2020, we had 76 full-time employees. As our development and commercialization plans and strategies develop, we will need to expand the size of our
employee  base  for  managerial,  operational,  sales,  marketing,  financial  and  other  resources.  Future  growth  would  impose  significant  added  responsibilities  on  members  of
management, including the need to identify, recruit, maintain, motivate and integrate additional employees. In addition, our management may have to divert a disproportionate
amount of its attention away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. Our future financial performance and
our ability to commercialize our drug candidates and our ability to compete effectively will depend, in part, on our ability to effectively manage our future growth.

Future capital raises may dilute our existing stockholders’ ownership and/or have other adverse effects on our operations.

If we raise additional capital by issuing equity securities, our existing stockholders’ percentage ownership will be reduced and these stockholders may experience substantial
dilution. We may also issue equity securities that provide for rights, preferences and privileges senior to those of our common stock. If we raise additional funds by issuing debt
securities, these debt securities would have rights senior to those of our common stock and the terms of the debt securities issued could impose significant restrictions on our
operations, including liens on our assets. If we raise additional funds through collaborations and licensing arrangements, we may be required to relinquish some rights to our
technologies or candidate products, or to grant licenses on terms that are not favorable to us.

44

 
 
 
 
 
 
 
If we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business strategy. In addition, the loss of
the  services  of  certain  key  employees,  including  Yuval  Cohen,  our  Chief  Executive  Officer,  Barbara  White,  our  Chief  Medical  Officer,  Craig  Millian,  our  Chief
Commercial Officer, and Sean Moran, our Chief Financial Officer would adversely impact our business prospects.

Our ability to compete in the highly competitive pharmaceuticals industry depends in large part upon our ability to attract highly qualified managerial, scientific and medical
personnel. In order to induce valuable employees to remain with us, we intend to provide employees with stock options that vest over time. The value to employees of stock
options that vest over time will be significantly affected by movements in the price of our common stock that we will not be able to control and may at any time be insufficient
to counteract more lucrative offers from other companies.

Our management team has expertise in many different aspects of drug development and commercialization. However, we will need to hire additional personnel as we further
develop our drug candidates. Competition for skilled personnel in our market is intense and competition for experienced scientists may limit our ability to hire and retain highly
qualified  personnel  on  acceptable  terms.  Despite  our  efforts  to  retain  valuable  employees,  members  of  our  management,  scientific  and  medical  teams  may  terminate  their
employment with us on short notice. We have entered into employment agreements with certain of our executive officers. However, these employment arrangements provide
for  at-will  employment,  which  means  that  any  of  our  employees  could  leave  our  employment  at  any  time,  with  or  without  notice.  The  loss  of  the  services  of  any  of  our
executive officers or other key employees could potentially harm our business, operating results or financial condition. In particular, we believe that the loss of the services of
Yuval  Cohen,  Ph.D.,  our  Chief  Executive  Officer,  Barbara  White,  M.D.,  our  Chief  Medical  Officer,  Craig  Millian,  our  Chief  Commercial  Officer  and  Sean  Moran,  C.P.A.,
M.B.A., our Chief Financial Officer, would have a material adverse effect on our business. Our success also depends on our ability to continue to attract, retain and motivate
highly skilled junior, mid-level, and senior managers as well as junior, mid-level, and senior scientific and medical personnel.

Other pharmaceutical companies with which we compete for qualified personnel have greater financial and other resources, different risk profiles, and a longer history in the
industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to
high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-quality personnel, the rate and success at which we can develop and
commercialize product candidates would be limited.

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

We face a potential risk of product liability as a result of the clinical testing of our drug candidates and will face an even greater risk if we commercialize our drug candidates.
For example, we may be sued if any product we develop or any materials that we use in our products allegedly causes injury or is found to be otherwise unsuitable during
product testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of
dangers  inherent  in  the  product,  negligence,  strict  liability  and  a  breach  of  warranties.  Claims  could  also  be  asserted  under  state  consumer  protection  acts.  If  we  cannot
successfully  defend  ourselves  against  product  liability  claims,  we  may  incur  substantial  liabilities  or  be  required  to  limit  commercialization  of  our  drug  candidates.  Even
successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

● decreased demand for our drug candidates;
● injury to our reputation;
● withdrawal of clinical trial participants;
● costs to defend the related litigation;
● a diversion of management’s time and our resources;
● substantial monetary awards to trial participants or patients;
● product recalls, withdrawals or labeling, marketing or promotional restrictions;
● the inability to commercialize our drug candidates; and
● a decline in the value of our stock.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our  inability  to  obtain  and  retain  sufficient  product  liability  insurance  at  an  acceptable  cost  to  protect  against  potential  product  liability  claims  could  prevent  or  inhibit  the
commercialization of products we develop. We intend to obtain product liability insurance covering our clinical trials. Although we will maintain such insurance, any claim that
may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits
of our insurance coverage. Our insurance policies also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may
have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have,
or be able to obtain, sufficient capital to pay such amounts.

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

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

Risks Related to our Common Stock

We will be unable to issue additional shares for future capital raising transactions or strategic transactions unless we obtain stockholder approval to amend our certificate
of incorporation to increase the number of authorized shares of our common stock available for issuance.

We have 150,000,000 authorized shares of common stock. As of March 15, 2021, we have 125,033,006 shares of common stock outstanding and 23,370,094 shares of common
stock  reserved  for  future  issuance  related  to  stock  options  and  warrants.  As  a  result,  as  of  March  15,  2021,  we  have  approximately  90,694  shares  of  authorized  shares  of
common stock available for future issuance. We will be limited by the number of additional shares available for future capital raising transactions or business development
transactions unless we obtain stockholder approval of an amendment to our certificate of incorporation to increase the number of authorized shares of common stock. We plan
to solicit the approval of our stockholders to amend our certificate of incorporation to increase the number of authorized shares of common stock, but we cannot be certain that
our stockholders will approve the amendment. A delay in securing, or a failure to secure, stockholder approval to amend our certificate of incorporation could cause a delay in
our future capital raising, collaboration, partnership or other strategic transactions, and may have a material adverse effect on our business and financial condition.

Our affiliates may control our company for the foreseeable future, including the outcome of matters requiring stockholder approval.

Our  officers,  directors,  and  five  percent  stockholders  collectively  owned  approximately  20.2%  of  our  outstanding  shares  of  common  stock  as  of  December  31,  2020.  This
concentration  of  voting  power  and  control  could  have  a  significant  effect  in  delaying,  deferring  or  preventing  an  action  that  might  otherwise  be  beneficial  to  our  other
stockholders and be disadvantageous to our stockholders with interests different from those entities and individuals. Certain of these individuals also have significant control
over our business, policies and affairs as officers or directors of our company. Therefore, you should not invest in reliance on your ability to have any control over our company.

An active, liquid trading market for our common stock may not be sustained.

Presently, our common stock is traded on the Nasdaq Global Market, or Nasdaq, and an investment in our company may require a long-term commitment, with no certainty of
return. If we are unable to maintain an active, liquid active trading market:

● investors may have difficulty buying and selling or obtaining market quotations;
● market visibility for shares of our common stock may be limited; and
● a lack of visibility for shares of our common stock may have a depressive effect on the market price for shares of our common stock.

The lack of an active market could impair your ability to sell your shares at the time you wish to sell them or at a price that you consider reasonable. The lack of an active
market may also reduce the fair market value of your shares. An inactive market may also impair our ability to raise capital to continue to fund operations by selling shares and
may impair our ability to acquire additional intellectual property assets by using our shares as consideration.

46

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We are currently listed on the Nasdaq Global Market. If we are unable to maintain listing of our securities on the Nasdaq Global Market or any stock exchange, our stock
price could be adversely affected and the liquidity of our stock and our ability to obtain financing could be impaired and it may be more difficult for our stockholders to sell
their securities.

Although our common stock is currently listed on the Nasdaq Global Market, we may not be able to continue to meet the exchange’s minimum listing requirements or those of
any other national exchange. If we are unable to maintain listing on Nasdaq or if a liquid market for our common stock does not develop or is sustained, our common stock may
remain thinly traded.

The Listing Rules of Nasdaq require listing issuers to comply with certain standards in order to remain listed on its exchange. If, for any reason, we should fail to maintain
compliance with these listing standards and Nasdaq should delist our securities from trading on its exchange and we are unable to obtain listing on another national securities
exchange, a reduction in some or all of the following may occur, each of which could have a material adverse effect on our stockholders:

● the liquidity of our common stock;
● the market price of our common stock;
● our ability to obtain financing for the continuation of our operations;
● the number of institutional and general investors that will consider investing in our common stock;
● the number of investors in general that will consider investing in our common stock;
● the number of market makers in our common stock;
● the availability of information concerning the trading prices and volume of our common stock; and
● the number of broker-dealers willing to execute trades in shares of our common stock.

The market price of our common stock may be significantly volatile.

The market price for our common stock may be volatile and subject to wide fluctuations in response to factors including the following:

● actual or anticipated fluctuations in our quarterly or annual operating results;
● changes in financial or operational estimates or projections;
● conditions in markets generally;
● changes in the economic performance or market valuations of companies similar to ours; and
● general economic or political conditions in the United States or elsewhere.

In particular, the market prices of biotechnology companies like ours have been highly volatile due to factors, including, but not limited to:

● any delay or failure to conduct a clinical trial for our product or receive approval from the FDA and other regulatory agencies;
● developments or disputes concerning a company’s intellectual property rights;
● technological innovations of such companies or their competitors;
● changes in market valuations of similar companies;
● announcements  by  such  companies  or  their  competitors  of  significant  contracts,  acquisitions,  strategic  partnerships,  joint  ventures,  capital  commitments,  new

technologies, or patents; and

● failure to complete significant transactions or collaborate with vendors in manufacturing a product.

The securities market has from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies.
These market fluctuations may also materially and adversely affect the market price of shares of our common stock.

Future sales of shares by existing stockholders could cause our stock price to decline.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large
number of shares of common stock intend to sell shares, could reduce the market price of our common stock.

47

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
As of December 31, 2020, we had outstanding options to purchase an aggregate of 14,289,643 shares of our common stock at a weighted average exercise price of $5.15 per
share and warrants to purchase an aggregate of 1,506,206 shares of our common stock at a weighted average exercise price of $9.46 per share. The exercise of such outstanding
options and warrants will result in further dilution of your investment. If our existing stockholders sell substantial amounts of our common stock in the public market, or if the
public perceives that such sales could occur, this could have an adverse impact on the market price of our common stock, even if there is no relationship between such sales and
the performance of our business.

We do not currently intend to pay dividends on our common stock in the foreseeable future, and consequently, your ability to achieve a return on your investment will
depend on appreciation in the price of our common stock.

We have never declared or paid cash dividends on our common stock and do not anticipate paying any cash dividends to holders of our common stock in the foreseeable future.
Consequently,  investors  must  rely  on  sales  of  their  common  stock  after  price  appreciation,  which  may  never  occur,  as  the  only  way  to  realize  any  future  gains  on  their
investments. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which our investors have purchased their shares.

There may be limitations on the effectiveness of our internal controls, and a failure of our control systems to prevent error or fraud may materially harm our company.

We are required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by our management on, among other things, the effectiveness of our internal control
over  financial  reporting.  This  assessment  will  need  to  include  disclosure  of  any  material  weaknesses  identified  by  our  management  in  our  internal  control  over  financial
reporting.  A  material  weakness  is  a  deficiency,  or  combination  of  deficiencies,  in  internal  control  over  financial  reporting  such  that  there  is  a  reasonable  possibility  that  a
material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis.

Effective  internal  control  over  financial  reporting  is  necessary  for  us  to  provide  reliable  and  timely  financial  reports  and,  together  with  adequate  disclosure  controls  and
procedures,  are  designed  to  reasonably  detect  and  prevent  fraud.  Any  failure  to  implement  required  new  or  improved  controls,  or  difficulties  encountered  in  their
implementation could cause us to fail to meet our reporting obligations. Undetected material weaknesses in our internal control over financial reporting could lead to financial
statement restatements and require us to incur the expense of remediation.

We do not expect that our disclosure controls or internal control over financial reporting will prevent or detect all error or all fraud. We may in the future discover weaknesses
in our system of internal control over financial reporting that could result in a material misstatement of our financial statements. A control system, no matter how well designed
and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no
evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. If
we identify one or more material weaknesses in our internal controls, investors could lose confidence in the reliability of our financial statements, the market price of our stock
could decline and we could be subject to sanctions or investigations by The Nasdaq Stock Market, the SEC or other regulatory authorities. Failure of our control systems to
detect or prevent error or fraud could materially adversely impact us.

48

 
 
 
 
 
 
 
 
 
We may be unable to complete our analysis of our internal controls over financial reporting in a timely manner, or these internal controls may not be determined to be
effective, which may adversely affect investor confidence in our company and, as a result, the value of our common stock.

We  may  not  be  able  to  complete  our  evaluation  and  testing  of  our  internal  control  over  financial  reporting  and  any  required  remediation  in  a  timely  fashion.  During  the
evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal
controls are effective.

If we are unable to assert that our internal control over financial reporting is effective, or, if applicable, our independent registered public accounting firm is unable to express
an opinion on the effectiveness of our internal controls, we could lose investor confidence in the accuracy and completeness of our financial reports, which would cause the
price of our common stock to decline, and we may be subject to investigation or sanctions by the SEC. We will also be required to disclose changes made in our internal control
and procedures on a quarterly basis.

If we identify a material weakness, our remediation efforts may not enable us to avoid a material weakness in our internal control over financial reporting in the future. Any of
the foregoing occurrences, should they come to pass, could negatively impact the public perception of our company, which could have a negative impact on our stock price.

Upon dissolution of our company, you may not recoup all or any portion of your investment.

In the event of a liquidation, dissolution or winding-up of our company, whether voluntary or involuntary, the proceeds and/or assets of our company remaining after giving
effect to such transaction, and the payment of all of our debts and liabilities and distributions required to be made to holders of any outstanding preferred stock will then be
distributed to the stockholders of common stock on a pro rata basis. There can be no assurance that we will have available assets to pay to the holders of common stock, or any
amounts, upon such a liquidation, dissolution or winding-up of our Company. In this event, you could lose some or all of your investment.

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

We have incurred substantial losses during our history and do not expect to become profitable in the near future, and we may never achieve profitability. Unused federal net
operating losses for tax years beginning before January 1, 2018 may be carried forward to offset future taxable income, if any, until such unused net operating losses expire.
Under legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act, or the Tax Act, as modified by legislation enacted on March 27, 2020, entitled the Coronavirus
Aid,  Relief,  and  Economic  Security  Act,  or  the  CARES  Act,  federal  net  operating  losses  incurred  in  tax  years  beginning  after  December  31,  2017,  can  be  carried  forward
indefinitely, but the deductibility of such federal net operating losses in tax years beginning after December 31, 2020 is limited to 80% of taxable income. In addition, as a
result  of  our  merger  in  April  2014  with  Corbus  Pharmaceuticals,  Inc.,  our  wholly-owned  subsidiary,  our  ability  to  utilize  our  federal  net  operating  loss,  carryforwards  and
federal tax credit prior to that date may be limited under Sections 382 of the Internal Revenue Code. The limitations apply if an “ownership change,” as defined by Section 382,
occurs. Generally, an ownership change occurs if the percentage of the value of the stock that is owned by one or more direct or indirect “five percent shareholders” increases
by more than 50 percentage points over their lowest ownership percentage at any time during the applicable testing period (typically three years). In addition, future changes in
our stock ownership, which may be outside of our control, may trigger an “ownership change” and, consequently, Section 382 limitations. As a result, if we earn net taxable
income, our ability to use our pre-change net operating loss carryforwards and other tax attributes to offset United States federal taxable income may be subject to limitations,
which could potentially result in increased future tax liability to us.

Legislation or other changes in U.S. tax law could adversely affect our business and financial condition.

The rules dealing with U.S. federal, state, and local income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue
Service and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application) could adversely affect us or holders of our common stock. In
recent years, many changes have been made to applicable tax laws and changes are likely to continue to occur in the future. For example, the Tax Act, made significant changes
to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%; limitation of the tax deduction for interest expense to
30%  of  adjusted  earnings  (except  for  certain  small  businesses);  and,  subject  to  certain  changes  in  tax  law  made  by  the  CARES  Act  as  discussed  above,  limitation  of  the
deduction of net operating losses generated in tax years beginning after December 31, 2017 to 80% of taxable income, indefinite carryforward of net operating losses generated
in tax years after 2018 and elimination of net operating loss carrybacks generated in tax years ending after December 31, 2017; changes in the treatment of offshore earnings
regardless of whether they are repatriated; current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations, mandatory capitalization of
research and development expenses beginning in 2022; immediate deductions for certain new investments instead of deductions for depreciation expense over time; further
deduction limits on executive compensation; and modifying, repealing and creating many other business deductions and credits, including the reduction in the orphan drug
credit from 50% to 25% of qualifying expenditures. We continue to examine the impact this tax reform legislation may have on our business. Notwithstanding the reduction in
the corporate income tax rate, the overall impact of the Tax Act is uncertain and our business and financial condition could be adversely affected. The impact of this tax reform
on holders of our common stock is also uncertain and could be adverse. This periodic report does not discuss any such tax legislation or the manner in which it might affect us
or our stockholders in the future. We urge our stockholders to consult with their legal and tax advisors with respect to such legislation. In addition, the CARES Act included
certain changes in tax law intended to stimulate the U.S. economy in light of the COVID-19 outbreak, including temporary beneficial changes to the treatment of net operating
losses, interest deductibility limitations and payroll tax matters.

It cannot be predicted whether, when, in what form, or with what effective dates, new tax laws may be enacted, or regulations and rulings may be enacted, promulgated or
issued under existing or new tax laws, which could result in an increase in our or our shareholders’ tax liability or require changes in the manner in which we operate in order to
minimize or mitigate any adverse effects of changes in tax law or in the interpretation thereof.

Our  certificate  of  incorporation,  as  amended,  allows  for  our  board  to  create  new  series  of  preferred  stock  without  further  approval  by  our  stockholders,  which  could
adversely affect the rights of the holders of our common stock.

Our  board  of  directors  has  the  authority  to  fix  and  determine  the  relative  rights  and  preferences  of  preferred  stock.  We  anticipate  that  our  board  of  directors  will  have  the
authority to issue up to 10,000,000 shares of our preferred stock without further stockholder approval. As a result, our board of directors could authorize the issuance of a series
of preferred stock that would grant to holders the preferred right to our assets upon liquidation and the right to receive dividend payments before dividends are distributed to the
holders of common stock. In addition, our board of directors could authorize the issuance of a series of preferred stock that has greater voting power than our common stock or
that is convertible into our common stock, which could decrease the relative voting power of our common stock or result in dilution to our existing stockholders.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with our financial statements and the related notes and the
other  financial  information  included  elsewhere  in  this  Annual  Report.  This  discussion  contains  forward-looking  statements  that  involve  risks  and  uncertainties.  Our  actual
results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed below and elsewhere in this
Annual Report, particularly those under “Risk Factors.”

Overview

We are a Phase 3, clinical-stage pharmaceutical company focused on the development and commercialization of novel therapeutics that target the endocannabinoid
system in the fields of autoimmunity, fibrosis, and cancer. We are developing a diverse pipeline of drug candidates across several distinct programs, including small molecules
as well as biologics, as well as evaluating potential external candidates complimentary to our existing programs.

51

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our pipeline includes the following programs:

1. Lenabasum,  a  novel,  synthetic,  oral,  CB2  agonist  designed  to  resolve  chronic  inflammation,  limit  fibrosis  and  support  tissue  repair.  Lenabasum  is  in  clinical
development for treatment of autoimmune diseases. We are currently evaluating lenabasum for safety and efficacy in a Phase 3 study in dermatomyositis, as well as a
Phase 2 study in SLE”.

2. Peripherally-restricted CB1 inverse agonists that are designed to normalize metabolic abnormalities or limit inflammation and fibrosis. We are currently evaluating
these compounds in pre-clinical studies for the treatment of metabolic disorders and for fibrotic disorders. We are evaluating certain compounds as potential candidates
for further clinical development.

3. Novel CB2  agonists  that  are  designed  to  limit  cancer  cell  growth  directly  and  reduce  the  fibrosis  and  immunosuppression  in  the  tumor  microenvironment  that  are
associated with tumor growth, metastasis, and resistance to treatment with drugs such as checkpoint inhibitors. We are currently evaluating these compounds in pre-
clinical studies for the treatment of cancer, in combination with other cancer therapies such as checkpoint inhibitors. We are evaluating certain compounds as potential
candidates for further clinical development.

Lenabasum selectively binds to CB2, which is preferentially expressed on activated immune cells, fibroblasts and other cell types, including muscle and bone cells.
Lenabasum reduces inflammation and limits fibrosis, without immunosuppression. Lenabasum inhibits production of inflammatory cytokines and eicosanoids and stimulates
the production of mediators (Specialized Pro-resolving Lipid Mediators) that resolve inflammation. It inhibits transformation of fibroblasts into myofibroblasts and production
of fibrotic growth factors and collagen. These biologic effects have been demonstrated in cells, animal models, and humans.

The  U.S.  Food  and  Drug Administration,  or  FDA,  has  granted  lenabasum  Orphan  Drug  Designation  as  well  as  Fast  Track  Status  for  systemic  sclerosis  and  cystic
fibrosis,  and  Orphan  Drug  Designation  for  dermatomyositis.  The  European  Medicines  Authority,  or  EMA,  has  granted  lenabasum  Orphan  Drug  Designation  for  systemic
sclerosis, cystic fibrosis, and dermatomyositis.

In 2020, we announced that lenabasum did not meet the primary endpoints in our RESOLVE-1 Phase 3 study of lenabasum for the treatment of systemic sclerosis or
our Phase 2b study of lenabasum for the treatment of cystic fibrosis. Currently, no patients with systemic sclerosis or cystic fibrosis are being treated with lenabasum. We are
preparing the data from our RESOLVE-1 Study for publication and will decide on the next steps in the development process for systemic sclerosis pending the outcome of our
Phase  3  study  of  lenabasum  for  the  treatment  of  dermatomyositis  (the  “DETERMINE  Study”).  We  are  preparing  the  data  from  our  Phase  2b  study  of  lenabasum  for  the
treatment of cystic fibrosis for publication, but currently we do not have plans for additional clinical studies in cystic fibrosis.

In  December  2018,  we  initiated  the  DETERMINE  Study,  our  Phase  3  double-blind  placebo-controlled  multi-center  international  clinical  study. The  DETERMINE
Study is fully enrolled with 176 patients. In January, 2021, we submitted a protocol amendment to the FDA to shorten the duration of the DETERMINE Study from 52 weeks
to 28 weeks. Subjects in the DETERMINE Study are randomized to receive lenabasum 20 mg twice per day, lenabasum 5 mg twice per day, or placebo twice per day in a 2:1:2
ratio.  The  primary  efficacy  outcome,  which  will  be  measured  at  week  28,  is  the  American  College  of  Rheumatology/European  League  Against  Rheumatism  2016  Total
Improvement  Score,  which  is  a  weighted  composite  measure  of  improvement  from  baseline  in  six  endpoints,  including  Physician  Global  Assessment  of  Disease  Activity,
Physician Global Assessment of Extramuscular Disease Activity, Patient Global Assessment of Disease Activity, Health Assessment Questionnaire (patient-reported disability),
Manual Muscle Testing, and muscle enzymes. Change from Baseline in the Cutaneous Dermatomyositis Activity and Severity index activity (CDASI) score is one of several
secondary efficacy outcomes in the Phase 3 study. Last subject, last dose in the placebo-controlled part of the DETERMINE Study has been completed in the first fiscal quarter
of 2021, with topline data expected in the second fiscal quarter of 2021.

Since  our  inception,  we  have  devoted  substantially  all  of  our  efforts  to  business  planning,  research  and  development,  recruiting  management  and  technical  staff,
acquiring operating assets and raising capital. Our research and development activities have included conducting pre-clinical studies, developing manufacturing methods and
the manufacturing of our drug lenabasum for clinical trials and conducting clinical studies in patients.

In September 2018, pursuant to a license agreement (the ‘Jenrin Agreement”) with Jenrin Discovery LLC (“Jenrin”) we acquired an exclusive worldwide license to
develop, manufacture and market drug candidates from more than 600 compounds targeting the endocannabinoid system. The portfolio of compounds includes cannabinoid
candidates targeting liver, lung, heart and kidney fibrotic diseases.

On January 3, 2019, we entered into a strategic collaboration with Kaken Pharmaceutical Co., Ltd. (“Kaken”) for the development and commercialization in Japan of
our  investigational  drug  lenabasum  for  the  treatment  of  systemic  sclerosis  and  dermatomyositis.  Under  the  terms  of  the  agreement,  Kaken  receives  an  exclusive  license  to
commercialize and market lenabasum in Japan for systemic sclerosis and dermatomyositis. In March 2019, Kaken made an upfront payment to us of $27 million. We are also
eligible to receive up to $173 million upon achievement of certain regulatory, development and sales milestones as well as double- digit royalties from Kaken.

On January 30, 2019, we consummated an underwritten public offering of shares of our common stock pursuant to which we sold an aggregate of 6,198,500 shares of
our  common  stock  at  a  purchase  price  of  $6.50  per  share  with  gross  proceeds  to  us  totaling  approximately  $40.3  million,  less  estimated  issuance  costs  incurred  of
approximately $2.6 million.

On February 11, 2020, we consummated an underwritten public offering of shares of our common stock pursuant to which we sold an aggregate of 7,666,667 shares of
our  common  stock  at  a  purchase  price  of  $6.00  per  share  with  gross  proceeds  to  us  totaling  approximately  $46.0  million,  less  estimated  issuance  costs  incurred  of
approximately $3.0 million.

On April 7, 2020, we entered into an Open Market Sale AgreementSM (“April 2020 Sale Agreement”) with Jefferies LLC (“Jefferies”) pursuant to which Jefferies is
serving  as  our  sales  agent  to  sell  up  to  $75,000,000  of  shares  of  the  Company’s  common  stock  through  an  “at  the  market  offering”.  As  of  December  31,  2020  we  sold
10,539,374 shares of our common stock under the April 2020 Sale Agreement for gross proceeds to us totaling $75,000,000, less issuance costs incurred of approximately
$2,250,000.

On July 28, 2020, we entered into the Loan Agreement with our subsidiary, Corbus Pharmaceuticals, Inc., as borrower, us, as guarantor, each lender party thereto (the
“Lenders”), K2 HealthVentures LLC (“K2HV”), an unrelated third party, as administrative agent for the Lenders, and Ankura Trust Company, LLC, an unrelated third party, as
collateral agent for the Lenders, pursuant to which K2HV may provide us with term loans in an aggregate principal amount of up to a $50,000,000.

On August 7, 2020, we entered into an Open Market Sale AgreementSM (the “August 2020 Sale Agreement”) with Jefferies, as sales agent, pursuant to which we may
issue and sell, from time to time, through Jefferies, shares of our common stock. As of August 7, 2020, we are authorized to offer and sell up to $150 million of our common
stock pursuant to the August 2020 Sale Agreement. As of December 31, 2020 we have sold 15,546,151 shares of our common stock under the August 2020 Sale Agreement for
gross proceeds totaling $21,404,000, less issuance costs incurred of approximately $642,000.

We  expect  the  cash  and  cash  equivalents  of  approximately  $85.4  million  at  December  31,  2020,  $58.9  million  of  proceeds  raised  from  the  August  2020  Sale
Agreement from January 1, 2021 through March 15, 2021, and the remaining $2.5 million of proceeds that we expect to receive under the 2018 CFF Award before the end of
the first half of 2021 to be sufficient to meet our operating and capital requirements into 2024, based on planned expenditures.

Financial Operations Overview

We are a clinical stage pharmaceutical company and have not generated any revenues from the sale of products. We have never been profitable and at December 31,
2020, we had an accumulated deficit of approximately $304.1 million. Our net losses for the years ended December 31, 2020 and 2019 were approximately $111,269,000 and
$71,454,000, respectively.

We expect to continue to incur significant expenses for the foreseeable future. We expect our expenses to decline in 2021 due to the completion of our clinical studies
in systemic sclerosis and cystic fibrosis in 2020 and dermatomyositis in 2021. While we expect expenses to decline in 2021, we will still incur significant operating losses and
accordingly we will need additional financing to support our continuing operations. We will seek to fund our operations through public or private equity or debt financings or
other sources, which may include government grants and collaborations with third parties. Adequate additional 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. We will need to
generate significant revenues to achieve profitability, and we may never do so.

We expect to continue to incur operating losses for at least the next several years in connection with our ongoing activities, as we:

● conduct preclinical and clinical trials for our product candidates in DM, systemic lupus erythematosus and other indications;

● continue our research and development efforts; and

● manufacture clinical study materials.

Critical Accounting Policies

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The
preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

On an ongoing basis, we evaluate our estimates and judgments for all assets and liabilities, including those related to stock-based compensation expense. We base our
estimates  and  judgments  on  historical  experience,  current  economic  and  industry  conditions  and  on  various  other  factors  that  are  believed  to  be  reasonable  under  the
circumstances. This forms 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.

53

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We believe that full consideration has been given to all relevant circumstances that we may be subject to, and the consolidated financial statements accurately reflect

our best estimate of the results of operations, financial position and cash flows for the periods presented.

Revenue Recognition

Revenue from awards for the years ended December 31, 2020 and 2019 was approximately $3,937,000 and $9,144,000, respectively, and pertains only to the 2018
CFF  Award.  No  revenue  from  licenses  was  recognized  for  the  year  ended  December  31,  2020.  Revenue  from  licenses  for  the  year  ended  December  31,  2019  included  the
recognition  of  the  $27,000,000  upfront  payment  received  from  Kaken  in  March  2019  for  which  we  satisfied  the  combined  performance  obligation  by  June  30,  2019,  upon
which we recognized the $27,000,000 as revenue in the second quarter of 2019.

We will assess any new agreements we enter into under GAAP, including whether such agreements fall under the scope of such standard. This standard applies to all
contracts  with  customers,  except  for  contracts  that  are  within  the  scope  of  other  standards,  such  as  leases,  insurance,  collaboration  arrangements  and  financial  instruments.
Under  GAAP,  an  entity  recognizes  revenue  when  its  customer  obtains  control  of  promised  goods  or  services,  in  an  amount  that  reflects  the  consideration  which  the  entity
expects  to  receive  in  exchange  for  those  goods  or  services.  To  determine  revenue  recognition  for  contracts  with  customers,  the  entity  performs  the  following  five  steps:  (i)
identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the
performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The five-step model is applied to contracts when it
is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, we assess the
goods or services promised within each contract and determine those that are performance obligations, and assess whether each promised good or service is distinct. We then
recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Revenue associated with the performance obligation is being recognized as revenue as the research and development services are provided using an input method,
according to the costs incurred as related to the research and development activities and the costs expected to be incurred in the future to satisfy the performance obligation. The
transfer of control occurs over this time period and, in management’s judgment, is the best measure of progress towards satisfying the performance obligation. The research and
development services related to this performance obligation are expected to be performed over an approximately three-year period expected to be completed in the first half of
2021. Amounts received prior to revenue recognition are recorded as deferred revenue. Amounts expected to be recognized as revenue within the 12 months following the
balance sheet date are classified as current portion of deferred revenue in the accompanying consolidated balance sheets. Amounts not expected to be recognized as revenue
within  the  12  months  following  the  balance  sheet  date  are  classified  as  deferred  revenue,  net  of  current  portion.  Amounts  recognized  as  revenue,  but  not  yet  received  or
invoiced are generally recognized as contract assets.

54

 
 
 
 
 
 
 
Revenue

To date, we have not generated any revenues from the sales of products. We do not expect to generate revenue from product sales unless and until we successfully
complete development and obtain regulatory approval for the marketing of lenabasum or other of our product candidates, which we expect will take a number of years and is
subject to significant uncertainty.

We recognized approximately $3,937,000 and $9,144,000 of revenue from awards in the years ended December 31, 2020 and 2019, respectively.

Amounts recognized in revenue from awards for the years ended December 31, 2020 and 2019 were in connection with our entry on January 26, 2018 into the Cystic
Fibrosis  Program  Related  Investment  Agreement  (“Investment  Agreement)  with  the  Cystic  Fibrosis  Foundation  (“CFF”),  a  non-profit  drug  discovery  and  development
corporation, pursuant to which we received a development award for up to $25 million in funding (the “2018 CFF Award”) to support a Phase 2b Clinical Trial (the “Phase 2b
Clinical Trial”) of lenabasum in patients with cystic fibrosis of which we received $6.25 million in the first quarter of 2018, $6.25 million in the second quarter of 2018, $5.0
million in the second quarter of 2019, and $5.0 million in the third quarter of 2020 upon our achievement of a milestone related to the progress of the Phase 2b Clinical Trial, as
set forth in the Investment Agreement. The $2.5 million remainder of the 2018 CFF Award is payable to us incrementally upon the achievement of the remaining milestones
related to the progress of the Phase 2b Clinical Trial, as set forth in the Investment Agreement and we expect to receive the remainder before the end of the first half of 2021.

Additionally, no revenue from licenses was recognized for the year ended December 31, 2020. Revenue from licenses for the year ended December 31, 2019 included
the recognition of the $27,000,000 upfront payment received from Kaken in March 2019 for which we satisfied the combined performance obligation by June 30, 2019, upon
which we recognized the $27,000,000 as revenue in the second quarter of 2019.

Research and Development

Research and development expenses are incurred for the development of lenabasum and other cannabinoid compounds and consist primarily of payroll and payments
to contract research and development companies. To date, these costs are related to generating pre-clinical data and the cost of manufacturing drug product for clinical trials and
conducting clinical trials. These costs are expected to decrease in 2021 as our RESOLVE-1 Study and our Phase 2b Study of lenabasum for the treatment of cystic fibrosis have
completed. The reduction in workforce announced in October 2020 will also contribute to reduction of future operating expenses.

General and Administrative Expenses

General and administrative expenses consist primarily of payroll, rent and professional services such as accounting and legal services. We anticipate that our general

and administrative expenses will decrease in the future as a result of the reduction in workforce announced in October 2020.

Other Income, Net

Other  income,  net  consists  primarily  refundable  research  and  development  tax  credits  that  were  earned  on  certain  research  and  development  expenses  we  incurred
primarily outside of the United States. Other income, net also consists of interest income we earn on interest-bearing accounts, interest expense incurred on our outstanding
debt, and realized and unrealized foreign currency exchange gains and losses.

Critical Accounting Policies and Estimates

Our  consolidated  financial  statements  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of  America.  The
preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

On  an  ongoing  basis,  we  evaluate  our  estimates  and  judgments  for  all  assets  and  liabilities,  including  those  related  to  stock-based  compensation  expense,  accrued
research and development expense, and operating lease right of use assets and liabilities. We base our estimates and judgments on historical experience, current economic and
industry  conditions  and  on  various  other  factors  that  are  believed  to  be  reasonable  under  the  circumstances.  This  forms  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.

We believe that full consideration has been given to all relevant circumstances that we may be subject to, and the consolidated financial statements accurately reflect

our best estimate of the results of operations, financial position and cash flows for the periods presented.

Accrued Research and Development Expenses

As part of the process of preparing financial statements, we are required to estimate and accrue expenses, the largest of which are research and development expenses.
This process involves: communicating with our applicable 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 actual cost; estimating and accruing expenses in our financial
statements as of each balance sheet date based on facts and circumstances known to us at the time; and periodically confirming the accuracy of our estimates with selected
service providers and making adjustments, if necessary.

Examples of estimated research and development expenses that we accrue include:

● fees paid to CROs in connection with nonclinical studies;

● fees paid to contract manufacturers in connection with the production of lenabasum for clinical trials;

● fees paid to CRO and research institutions in connection with conducting of clinical studies; and

● professional service fees for consulting and related services.

We base our expense accruals related to clinical studies on our estimates of the services performed pursuant to contracts with multiple research institutions and clinical
research organizations that conduct and manage clinical studies on our behalf. The financial terms of these agreements vary from contract to contract and may result in uneven
payment flows. Payments under some of these contracts depend on factors, such as the successful enrollment of patients and the completion of clinical study milestones. Our
service providers invoice us monthly in arrears for services performed. In accruing service fees, we estimate the time period over which services will be performed and the level
of effort to be expended in each period. If we do not identify costs that we have begun to incur or if we underestimate or overestimate the level of services performed or the
costs of these services, our actual expenses could differ from our estimates.

To  date,  we  have  not  experienced  significant  changes  in  our  estimates  of  accrued  research  and  development  expenses  following  each  applicable  reporting  period.
However, due to the nature of estimates, we cannot assure you that we will not make changes to our estimates in the future as we become aware of additional information
regarding the status or conduct of our clinical studies and other research activities.

Stock-Based Compensation

Stock options are granted with an exercise price at no less than fair market value at the date of the grant. The stock options normally expire ten years from the date of

grant. Stock option awards vest upon terms determined by our board of directors.

We recognize compensation costs resulting from the issuance of stock-based awards to employees, members of our Board of directors and consultants. The fair value
of each option grant was estimated as of the date of grant using the Black-Scholes option-pricing model. The fair value is amortized as compensation cost on a straight-line
basis over the requisite service period of the awards, which is generally the vesting period. We estimate volatility by analyzing the volatility of the trading price of our common
stock. We use historical data, as well as subsequent events occurring prior to the issuance of the consolidated financial statements, to estimate option exercise and employee
forfeitures within the valuation model. The expected term of options granted to employees under our stock plans is based on the average of the contractual term (generally 10
years)  and  the  vesting  period  (generally  48  months).  The  expected  term  of  options  granted  under  the  2014  Plan,  all  of  which  qualify  as  “plain  vanilla”  per  SEC  Staff
Accounting Bulletin 107, is based on the average of the 6.25 years. For non-employee options, the expected term is the contractual term. The risk-free rate is based on the yield
of a U.S. Treasury security with a term consistent with the option. We estimate the forfeiture rate at the time of grant and revise it, if necessary, in subsequent periods if actual
forfeitures differ from those estimates. Forfeitures were estimated based on management’s expectation through industry knowledge and historical data. We have never paid
dividends on our common stock and do not anticipate paying dividends on our common stock in the foreseeable future. Accordingly, we have assumed no dividend yield for
purposes of estimating the fair value of our share-based compensation.

The following assumptions were used to estimate the fair value of stock options granted using the Black-Scholes option pricing model for the years ended December

31, 2020 and 2019 is as follows:

Risk free interest rate
Expected dividend yield
Expected term in years
Expected volatility
Estimated forfeiture rate

Revenue  from  Awards  and  Licenses.  We  have  recognized  approximately  $3,937,000  and  $36,144,000  of  revenue  from  awards  and  licenses  in  the  years  ended

December 31, 2020 and 2019, respectively.

Revenue from awards for the years ended December 31, 2020 and 2019 was approximately $3,937,000 and $9,144,000, respectively, recognized in accordance with
ASC 606 and pertains only to the 2018 CFF Award. We received an aggregate of $12,500,000 during the year ended December 31, 2018 and an additional $5,000,000 during
the year ended December 31, 2019, and $5,000,000 in the third quarter of 2020 upon our achievement of a milestone related to the progress of the Phase 2b Clinical Trial, as set
forth in the Investment Agreement. The $2,500,000 remainder of the 2018 CFF Award is payable to us incrementally upon the achievement of the remaining milestones related
to the progress of the Phase 2b Clinical Trial, as set forth in the Investment Agreement and we expect to receive the remainder before the end of the first half of 2021.

Revenue for the year ended December 31, 2019 also included the recognition of revenue from licenses for the $27,000,000 upfront payment received from Kaken in
March 2019 for which we satisfied the combined performance obligation by June 30, 2019, upon which we recognized the $27,000,000 as revenue in the second quarter of
2019.

We assessed the 2018 CFF Award and the Kaken collaboration agreement for accounting under ASC 606. To determine revenue recognition for arrangements that an
entity  determines  are  within  the  scope  of  ASC  606,  the  entity  performs  the  following  five  steps:  (i)  identify  the  contract(s)  with  a  customer;  (ii)  identify  the  performance
obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when
(or as) the entity satisfies a performance obligation.

Research  and  Development.  Research  and  development  expenses  for  the  year  ended  December  31,  2020  totaled  approximately  $98,267,000,  an  increase  of
$8,662,000 over the $89,605,000 recorded for the year ended December 31, 2019. The increase in fiscal 2020 as compared to fiscal 2019 was primarily attributable to increases
of approximately $3,561,000 in clinical trial costs and $5,638,000 in compensation costs. These increases were partially offset by an approximate $537,000 decrease in stock-
based compensation expense.

During 2018, the Company formed a subsidiary in each of the United Kingdom and Australia and approximately 44% and 46% of research and development expenses

recorded for the year ended December 31, 2020 and December 31, 2019 respectively was recorded in these entities.

General  and  Administrative.  General  and  Administrative  expense  for  the  year  ended  December  31,  2020  totaled  approximately  $28,480,000,  an  increase  of
$4,837,000 over the $23,643,000 recorded for the year ended December 31, 2019. The increase in fiscal 2020 as compared to fiscal 2019 was primarily attributable to increases
of approximately $3,119,000 in compensation costs, $1,014,000 stock-based compensation, $473,000 in insurance costs, and $376,000 in temporary help and recruiting costs.

Other  Income,  Net.  Other  income,  net  for  2020  was  approximately  $11,541,000  as  compared  to  approximately  $5,651,000  recorded  for  2019.  The  increase  of
$5,890,000 in 2020 as compared to 2019 was primarily attributable to approximately $9,574,000 increase in cash paid to us in 2020 from taxing authorities for refundable
research and development tax credits that were earned on certain research and development expenses we incurred primarily outside of the United States, offset by $251,000
related  to  the  derivative  liability  valuation  associated  with  the  Loan  Agreement  with  K2HV  and  $850,000  related  to  a  return  of  a  state  of  Massachusetts  research  and
development tax credit. In prior year we received approximately $472,000 for a refundable research and development tax credit and in 2020 approximately $378,000 became
due back to the state of Massachusetts. The net increase was also offset by a $2,256,000 decrease to interest income. This was the result of approximately $1,100,000 lower
interest income on excess cash and cash equivalents and $1,127,000 higher interest expense in 2020 as a result of entering into K2HV security and loan agreement.

Liquidity and Capital Resources

Since inception, we have experienced negative cash flows from operations. We have financed our operations primarily through sales of equity-related securities. In
addition, the majority of the costs of the SLE clinical trial has been or is expected to be funded by NIH grants, and our phase 2b cystic fibrosis trial was supported by the 2018
CFF Award. At December 31, 2020, our accumulated deficit since inception was approximately $304,093,000.

At December 31, 2020, we had total current assets of approximately $92,075,000 and current liabilities of approximately $31,898,000 resulting in working capital of

approximately $60,177,000. Of our total cash and cash equivalents of $85.4 million at December 31, 2020, $84.4 million was held within the United States.

Net cash used in operating activities for the year ended December 31, 2020 was approximately $99,686,000 which includes a net loss of approximately $111,269,000,
adjusted for non-cash expenses of approximately $14,789,000, principally related to stock-based compensation expense of $12,458,000, depreciation and amortization expense
of $1,124,000 and operating lease right of use asset amortization of $570,000, and approximately $3,205,000 of cash used by net working capital items, principally related to
the decrease in accounts payable.

Cash  used  in  investing  activities  for  the  year  ended  December  31,  2020  totaled  approximately  $484,000,  which  was  largely  related  to  payments  for  furniture  and

fixtures utilized in the build out of our office space in 2019.

58

 
 
 
 
 
 
 
 
 
 
 
 
Cash provided by financing activities for the year ended December 31, 2020 totaled approximately $154,875,000.

On February 11, 2020, we consummated an underwritten public offering of shares of our common stock pursuant to which we sold an aggregate of 7,666,667 shares of

our common stock at a purchase price of $6.00 per share with gross proceeds to us totaling $46,000,000, less estimated issuance costs incurred of approximately $3,147,000.

During the year ended December 31, 2020 we sold an aggregate of 26,085,525 shares of our common stock under the April 2020 Sale Agreement and August 2020

Sale Agreement for gross proceeds of approximately $96,404,000, less issuance costs incurred of approximately $2,892,000.

On July 28, 2020, we entered into the Loan Agreement with K2HV pursuant to which K2HV may provide us with term loans in an aggregate principal amount of up to
a $50,000,000 and we received the first tranche for $20,000,000 at closing. The second tranche for $20,000,000 and the third tranche for $10,000,000 will be made available at
our option subject to the achievement of certain clinical and regulatory milestones. The loan matures on August 1, 2024 and we are obligated to make interest only payments
for the first 24 months and then interest and equal principal payments for the next 24 months. Interest accrues at a variable annual rate equal to the greater of (i) 8.5% and (ii)
the rate of interest noted in The Wall Street Journal, Money Rates section, as the “Prime Rate” plus 5.25%, in each case, subject to a step-down of 25 basis points upon the
funding of the second tranche. K2HV may elect to convert up to $5,000,000 of the outstanding loan into common stock at a conversion price of $9.40 per share. At closing, we
issued a Warrant to K2HV exercisable for 86,206 shares of the Company’s common stock at an exercise price of $6.96 per share. We granted registration rights to the lenders in
connection with the Loan Agreement and the Warrant.

During the year ended December 31, 2020, we also received proceeds of approximately $756,000 from the issuance of 427,611 shares of our common stock upon the
exercise of stock options to purchase common stock. Cash provided by financing activities for the year ended December 31, 2020 included proceeds from issuances of notes
payable  of  approximately  $909,000,  offset  by  principal  payments  on  notes  payable  of  approximately  $952,000  in  connection  with  our  loan  agreements  with  financing
companies  to  fund  D&O  insurance  premiums.  The  terms  of  the  loan  that  we  entered  into  in  November  2019  stipulated  equal  monthly  payments  of  principal  and  interest
payments of $109,413 over a nine-month period. Interest accrued on this loan at an annual rate of 5.25% and the loan was paid in full in August 2020. In November 2020, the
Company  entered  into  a  loan  agreement  with  a  financing  company  for  $909,375  to  finance  one  of  the  Company’s  insurance  policies.  The  terms  of  the  loan  stipulate  equal
monthly payments of principal and interest payments of $103,112 over a nine-month period. Interest accrues on this loan at an annual rate of 4.89%.

We expect our cash and cash equivalents of approximately $85.4 million at December 31, 2020, combined with the $58.9 million of proceeds from the August 2020
Sale Agreement subsequent to December 31, 2020, and the expected final $2.5 million milestone payment from the CFF award will be sufficient to meet our operating and
capital requirements into 2024 based on current planned expenditures.

We will need to raise significant additional capital to continue to fund operations and the clinical trials for lenabasum. If we are unable to raise sufficient capital in the
future, we may be required to undertake cost-cutting measures, including delaying or discontinuing certain clinical activities. We may seek to sell common stock, preferred
stock or convertible debt securities, enter into a credit facility or another form of third-party funding or seek other debt financing. In addition, we may seek to raise cash through
collaborative agreements or from government grants. The sale of equity and convertible debt securities may result in dilution to our stockholders and certain of those securities
may have rights senior to those of our common shares. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing,
these  securities  or  other  debt  could  contain  covenants  that  would  restrict  our  operations.  Any  other  third-party  funding  arrangement  could  require  us  to  relinquish  valuable
rights.

The  source,  timing  and  availability  of  any  future  financing  will  depend  principally  upon  market  conditions,  and,  more  specifically,  on  the  progress  of  our  clinical

development programs.

Funding may not be available when needed, at all, or on terms acceptable to us. Lack of necessary funds may require us, among other things, to delay, scale back or

eliminate expenses including some or all of our planned clinical trials.

Contractual Obligations and Commitments

The following table presents information about our known contractual obligations as of December 31, 2020. It does not reflect contractual obligations that may have

arisen or may arise after that date. Except for historical facts, the information in this section is forward-looking information.

On  February  26,  2019,  we  amended  our  lease  (“February  2019  Lease  Agreement”)  pursuant  to  which  an  additional  30,023  square  feet  of  office  space  (“New
Premises”) will be leased by us in the same building for an aggregate total of 62,756 square feet of leased office space (“Total Premises”). The February 2019 Lease Agreement
constitutes a modification as it extends the original lease term and increases the scope of the lease (additional space provided under the amendment), which requires evaluation
of the remeasurement of the lease liability and corresponding right-of-use (“ROU”) asset. Accordingly, we reassessed the classification of the Leased Premises and remeasured
the  lease  liability  on  the  basis  of  the  extended  lease  term  using  the  20  additional  monthly  rent  payments  and  the  incremental  borrowing  rate  at  the  effective  date  of  the
modification of 9%. The remeasurement for the modification resulted in an increase to the lease liability and the ROU asset of approximately $855,000. We determined that the
New Premises will be treated as a new standalone operating lease under U.S. GAAP and recorded a lease liability and a right-of-use asset of approximately $2.7 million for this
lease.

Per the terms of the February 2019 Lease Agreement, the landlord agreed to reimburse us for $990,759 of leasehold improvements. The reimbursements are being
recognized  as  a  reduction  of  rent  expense  over  the  term  of  the  lease.  Additionally,  the  February  2019  Lease  Agreement  required  a  standby  irrevocable  letter  of  credit  of
$369,900, which may be reduced, if we are not in default under the February 2019 Lease Agreement, to $277,425 and $184,950 on the third and fourth anniversary of the
commencement date, respectively.

On October 25, 2019, we amended our lease (“October 2019 Lease Amendment”) pursuant to which the term of the lease was extended through November 30, 2026
and the existing office space under lease was expanded by 500 square feet for an aggregate total of 63,256 square feet of leased office space (“Amended Total Premises”). The
October  2019  Lease  Amendment  constitutes  a  modification  as  it  extends  the  original  lease  term  and  increases  the  scope  of  the  lease  (additional  space  provided  under  the
amendment), which requires evaluation of the remeasurement of the lease liability and corresponding ROU asset. The additional space did not result in a separate contract as
the rent increase was determined not to be commensurate with the standalone price for the additional right of use. Accordingly, we reassessed the classification of the Amended
Total Premises, which resulted in operating classification, and remeasured the lease liability on the basis of the extended lease term using the additional monthly rent payments
and the incremental borrowing rate at the effective date of the modification of 8%. The remeasurement for the modification resulted in an increase to the lease liability and the
ROU asset of approximately $381,000 that was recorded in the fourth quarter of 2019.

Pursuant  to  the  terms  of  our  non-cancelable  lease  agreements  in  effect  at  December  31,  2020,  the  following  table  summarizes  our  maturities  of  operating  lease

liabilities as of December 31, 2020:

We may enter into contracts in the normal course of business with clinical research organizations for clinical trials and clinical supply manufacturing and with vendors
for  pre-clinical  research  studies,  research  supplies  and  other  services  and  products  for  operating  purposes.  These  contracts  generally  provide  for  termination  on  notice,  and
therefore, we believe that our non-cancelable obligations under these agreements are not material. As of December 31, 2020, other than our leases in the table above, we had no
material Contractual Obligations or Commitments that will affect our future liquidity.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial
condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors, other than future royalty payments under
development award agreements discussed as follows:

Collaboration Agreement with Kaken

Pursuant  to  the  terms  of  the  Kaken  Agreement,  we  will  bear  the  cost  of,  and  be  responsible  for,  among  other  things,  conducting  the  clinical  studies  and  other
developmental  activities  for  the  Licensed  Products  in  the  Initial  Indications  in  the  Territory,  and  Kaken  will  bear  the  cost  of,  and  be  responsible  for,  among  other  things,
preparing  and  filing  applications  for  regulatory  approval  in  the Territory  and  for  commercializing  Licensed  Products  in  the  Territory,  and  will  use  commercially  reasonable
efforts to commercialize Licensed Products and obtain pricing approval for Licensed Products in the Territory.

In consideration of the license and other rights granted by us, Kaken paid us a $27,000,000 upfront cash payment in March 2019 and is obligated to pay potential
milestone  payments  to  us  totaling  up  to  approximately  $173,000,000  for  the  achievement  of  certain  development,  sales  and  regulatory  milestones.  In  addition,  during  the
Royalty Term (as defined below), Kaken is obligated to pay us royalties on sales of Licensed Products in the Territory, under certain conditions, in the double digits, which
royalty shall be reduced in certain circumstances. In particular, for so long as we supply Licensed Products to Kaken pursuant to a supply agreement to be entered into by the
parties, royalty payments shall be payable for each unit of Licensed Product that we supply as a percentage of the Japanese National Health Insurance price of the Licensed
Product. During any time in which a supply agreement is not in effect, royalty payments shall be changed to a rate to be agreed upon by the parties in good faith.

The Kaken Agreement will remain in effect on a Licensed Product-by-Licensed product basis and will expire upon the expiration of the Royalty Term for the final
Licensed Product. The “Royalty Term” means the period beginning on the date of the first commercial sale of the Licensed Product in Japan and ends on the latest of (i) the
expiration of the last valid claim of the royalty patents covering such Licensed Product in Japan, (ii) the expiration of regulatory exclusivity for such Licensed Product for such
Initial Indication in Japan, or (iii) ten (10) years after the first commercial sale of such Licensed Product for such Initial Indication in Japan. The Agreement may be terminated
by either party for material breach, upon a party’s insolvency or bankruptcy or upon a challenge by one party of any patents of the other party, and Kaken may terminate in
specified situations, including for a safety concern or clinical failure, or at its convenience following the second anniversary of the first commercial sale of a Licensed Product
in either of the Initial Indications in the Territory, with 180 days’ notice.

License Agreement with Jenrin

Pursuant to the terms of the Jenrin Agreement, we are obligated to pay potential milestone payments to Jenrin totaling up to $18.4 million for each compound we elect
to develop based upon the achievement of specified development and regulatory milestones. In addition, we are obligated to pay Jenrin royalties in the mid, single digits based
on net sales of any Licensed Products, as defined in the Jenrin Agreement, subject to specified reductions.

The Jenrin Agreement terminates on a country-by-country basis and product-by-product basis upon the expiration of the royalty term for such product in such country.
Each  royalty  term  begins  on  the  date  of  the  first  commercial  sale  of  the  licensed  product  in  the  applicable  country  and  ends  on  the  later  of  seven  years  from  such  first
commercial sale or the expiration of the last to expire of the applicable patents in that country. The Jenrin Agreement may be terminated earlier in specified situations, including
termination for uncured material breach of the Jenrin Agreement by either party, termination by Jenrin in specified circumstances, termination by Corbus with advance notice
and termination upon a party’s insolvency or bankruptcy.

2018 CFF Award

Pursuant to the terms of the Investment Agreement, we are obligated to make certain royalty payments to CFF, including a royalty payment of one and one-half times
the amount of the 2018 CFF Award, payable in cash within sixty days upon the first receipt of approval of lenabasum in the United States and a second royalty payment of one
and one-half times the amount of the 2018 CFF Award upon approval in another major market, as set forth in the Investment Agreement (the “Approval Royalty”). At our
election, we may satisfy the first of the two Approval Royalties in registered shares of our common stock. Additionally, we will owe to CFF a royalty payment equal to 10% of
any  amounts  we  receive  as  payment  under  the  collaboration  agreement  with  Kaken,  provided  that  the  total  royalties  that  we  will  be  required  to  pay  under  the  Investment
Agreement resulting from income from licenses or sales subject to the Investment Agreement are capped at five times the total amount of the 2018 CFF Award, and we may
credit such royalties against any royalties on net sales otherwise owed to CFF under the Investment Agreement. Accordingly, we were required to pay CFF $2,700,000 in May
2019, which is within 60 days of our receipt of the $27,000,000 upfront cash payment from Kaken described below.

61

 
 
 
 
 
 
 
 
 
 
 
Additionally, we are obligated to make (i) royalty payments to CFF of two and one-half percent of net sales from lenabasum due within sixty days after any quarter in
which such net sales occur in the Field, as defined in the Investment Agreement, (ii) royalty payments to CFF of one percent of net sales of Non-Field Products, as defined in
the Investment Agreement due within sixty days after any quarter in which such net sales occur, and (iii) royalty payments to CFF of ten percent of any amount that we and our
stockholders receive in connection with the license, sale, or other transfer to a third party of lenabasum, if indicated for the treatment or prevention of CF, or a change of control
transaction, except that such payment shall not exceed five times the amount of the 2018 CFF Award, with such payments to be credited against any other net sales royalty
payments due. Either CFF or we may terminate the Investment Agreement for cause, which includes our material failure to achieve certain commercialization and development
milestones. Our payment obligations survive the termination of the Investment Agreement.

2015 CFFT Award

Pursuant to the terms of the 2015 CFFT Award agreement, we are obligated to make royalty payments to CFFT contingent upon commercialization of lenabasum in
the Field of Use (as defined in the 2015 CFFT Award Agreement) as follows: (i) a royalty payment equal to five times the amount we receive under the 2015 CFFT Award
Agreement, up to $25 million, payable in three equal annual installments following the first commercial sale of lenabasum, the first of which is due within 90 days following
the first commercial sale of lenabasum, (ii) a royalty payment to CFFT equal to the amount we receive under the 2015 CFFT Award Agreement, up to $5 million, due in the
first  calendar  year  in  which  the  aggregate  cumulative  net  sales  of  lenabasum  in  the  Field  of  Use  exceed  $500  million,  and  (iii)  royalty  payment(s)  to  CFFT  of  up  to
approximately $15 million if we transfer, sell or license lenabasum in the Field of Use other than for certain clinical or development purposes, or if we enter into a change of
control transaction, with such payment(s) to be credited against the royalty payments due upon commercialization. The Field of Use is defined in the CFFT Award Agreement
as the treatment in humans of CF, asbestosis, bronchiectasis, byssinosis, chronic bronchitis/COPD hypersensitivity pneumonitis, pneumoconiosis, primary ciliary dyskinesis,
sarcoidosis  and  silicosis.  Either  CFFT  or  we  may  terminate  the  2015  CFFT  Award  Agreement  for  cause,  which  includes  our  material  failure  to  achieve  certain
commercialization and development milestones. Our payment obligations, if any, would survive the termination of the 2015 CFFT Award Agreement.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk is limited to our cash and cash equivalents, all of which have maturities of three months or less. The primary objectives of our investment
activities  are  to  preserve  principal,  provide  liquidity  and  maximize  income  without  significantly  increasing  risk.  Our  primary  exposure  to  market  risk  is  interest  income
sensitivity,  which  is  affected  by  changes  in  the  general  level  of  U.S.  interest  rates.  However,  because  of  the  short-term  nature  of  the  instruments  in  our  portfolio,  a  sudden
change in market interest rates would not be expected to have a material impact on our financial condition and/or results of operation.

Foreign Exchange Risk

The majority of our operations are based in the United States and, accordingly our transactions are denominated in U.S. Dollars. However, we have foreign currency
exposures related to our cash valued in the United Kingdom in British Pounds and Euros and our cash valued in Australia in Australian Dollars because our functional currency
is the U.S. Dollar in our foreign-based subsidiaries. Our foreign denominated assets and liabilities are remeasured each reporting period with any exchange gains and losses
recorded in our consolidated statements of operations.

Item 9A. CONTROLS AND PROCEDURES

Evaluation of Our Disclosure Controls

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the
Securities and Exchange Act of 1934 as amended (the “Exchange Act”) is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s
rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and our principal financial officer, or persons performing
similar functions, to allow timely decisions regarding required disclosure.

As of December 31, 2020, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act). Our management recognizes that any controls and procedures, no matter
how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-
benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded, based upon the evaluation described

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting, as such term is defined in Rule 13a-15(f) of the

Exchange Act .

Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in the “Internal Control-
Integrated Framework (2013)” issued by the Committee of Sponsoring Organization of the Treadway Commission. Based on this assessment, management concluded that, as of
December 31, 2020, our internal control over financial reporting was effective.

This annual report does not include an attestation report of our registered public accounting firm on internal control over financial reporting.

Remediation of Previously Reported Material Weaknesses

The  material  weaknesses  related  to  our  control  environment  and  our  information  technology  general  controls  governing  user  access  over  certain  information
technology (“IT”) systems that were previously reported in Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 were remediated during
our fiscal year ended December 31, 2020, and we determined that we maintained effective internal controls over our financial reporting as of December 31, 2020.

Management  took  significant  steps  to  remediate  the  control  deficiencies  that  led  to  the  material  weaknesses.  We  added  experienced  accounting  personnel  to  our
finance  staff,  implemented  software  to  assist  in  monitoring  internal  controls  and  engaged  an  outside  consulting  firm  to  help  us  evaluate  and  test  our  internal  controls.  We
successfully redesigned our IT control environment related to permissions and access to software applications and our financial control environment associated with the accrual
of costs from research and development contracts.

Changes in Internal Controls over Financial Reporting

Other than the changes described above, there were no other changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f))
under the Exchange Act) that occurred during the fourth quarter ended December 31, 2020, that has materially affected, or is reasonably likely to materially affect, our internal
control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Corbus Pharmaceuticals Holdings, Inc. and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Corbus Pharmaceuticals Holdings, Inc. and Subsidiaries (the “Company”) as of December 31, 2020 and
2019, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of 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 consolidated financial position of the Company as of December
31, 2020 and 2019, and the consolidated results of their operations and their cash flows of 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.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or  required  to  be
communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging,
subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we
are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Accruals for Research and Development Expenses and Clinical Trials

As described in Note 3 to the consolidated financial statements, at each balance sheet date the Company estimates its accrued clinical expenses resulting from its obligations
under contracts with vendors, clinical research organizations and consultants and under clinical site agreements in connection with conducting clinical trials, and may depend
on factors such as successful enrollment of certain numbers of patients, site initiation, and the completion of clinical trial milestones. The Company accounts for trial expenses
based on services that have been performed on the Company’s behalf and estimating the level of service performed and the associated cost incurred for the service when an
invoice has not been received or the Company has not otherwise been notified of the actual cost. The Company estimates the time period over which services will be performed
and the level of effort to be expended in each period. The Company’s accrual for clinical trial expenses of $16,322,000 is included in Accrued expenses on the December 31,
2020  consolidated  balance  sheet.  The  amounts  recorded  for  clinical  trial  expenses  represent  the  Company’s  estimate  of  the  unpaid  clinical  trial  expenses  based  on  the
information available to the Company at that time. The estimation of clinical trial expenses was also identified as a critical accounting estimate by management.

We  identified  the  accruals  for  research  and  development  expenses  and  clinical  trials  as  a  critical  audit  matter  due  to  the  significant  judgment  and  estimation  required  by
management in determining progress or state of completion of trials or services completed. This in turn led to a high degree of auditor subjectivity and significant audit effort
was required in performing our procedures and evaluating audit evidence relating to estimates made by management.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the financial statements. We obtained
an understanding and evaluated the design of controls over the Company’s estimation of clinical trial expenses, including the process of estimating the expenses incurred to date
based on the status of the clinical trials. Our procedures also included, among others, reading agreements and contract amendment with vendors in connection with conducting
clinical trials, and evaluating the significant assumptions described above and the methods used in developing the clinical trial estimates and calculating the amounts that were
unpaid at the balance sheet date. We confirmed the assumptions directly with the third parties involved in performing the clinical trial services on behalf of the Company. We
also made direct inquiries of financial and clinical client personnel regarding status and progress to completion of clinical trials and description of future commitments, and
verified  amounts  paid  to  date  under  each  contract  by  vouching  to  invoices  and  payment  support.  We  also  assessed  the  historical  accuracy  of  management’s  estimates,  and
compared the current estimate of expenses incurred to estimates previously made by management.

Corbus Pharmaceuticals Holdings, Inc.
Notes to Consolidated Financial Statements
December 31, 2020 and 2019

1. NATURE OF OPERATIONS

Business

Corbus Pharmaceuticals Holdings, Inc. (“the Company” or “Corbus”) is a clinical-stage pharmaceutical company focused on the development and commercialization of
novel therapeutics that target the endocannabinoid or immune system. The Company intends to pursue indications for our novel therapeutics that are autoimmune, fibrotic,
or metabolic diseases, or cancer. The Company is developing a diverse pipeline of drug candidates and plan to expand our pipeline through internal efforts and business
development.  Since  its  inception,  the  Company  has  devoted  substantially  all  of  its  efforts  to  business  planning,  research  and  development,  recruiting  management  and
technical staff, acquiring operating assets and raising capital. The Company’s business is subject to significant risks and uncertainties and the Company will be dependent
on raising substantial additional capital before it becomes profitable and it may never achieve profitability.

In response to the spread of COVID-19, the Company has taken temporary precautionary measures intended to help minimize the risk of the virus to its employees and
community, including temporarily requiring employees to work remotely, implementing remote monitoring procedures for clinical data and suspending all non-essential
travel worldwide for its employees.

The Company is continuing to monitor the impact of the COVID-19 pandemic on its business and operations.

2. LIQUIDITY

The  accompanying  consolidated  financial  statements  have  been  prepared  assuming  the  Company  will  continue  as  a  going  concern,  which  contemplates  continuity  of
operations,  realization  of  assets  and  the  satisfaction  of  liabilities  and  commitments  in  the  normal  course  of  business.  The  Company  has  incurred  recurring  losses  since
inception and as of December 31, 2020, had an accumulated deficit of $304,094,000. The Company anticipates operating losses to continue for the foreseeable future due
to,  among  other  things,  costs  related  to  research  funding,  development  of  its  product  candidates  and  its  preclinical  and  clinical  programs,  strategic  alliances  and  the
development of its administrative organization. The Company expects the cash and cash equivalents of $85,433,000 at December 31, 2020 and proceeds of subsequent
raises of capital (see Note 15) will be sufficient to meet its operating and capital requirements at least 12 months from the filing of this 10-K.

The  source,  timing  and  availability  of  any  future  financing  will  depend  principally  upon  market  conditions,  and,  more  specifically,  on  the  progress  of  the  Company’s
clinical development programs.

On February 11, 2020, the Company consummated an underwritten public offering of shares of its common stock (“February 2020 Offering”) (See Note 11).

On April  7,  2020,  the  Company  entered  into  an  Open  Market  Sale  AgreementSM  (“April  2020  Sale  Agreement”)  with  Jefferies  LLC  (“Jefferies”)  pursuant  to  which
Jefferies is serving as the Company’s sales agent to sell up to $75,000,000 of shares of the Company’s common stock through an “at the market offering”. During the year
ended  December  31,  2020,  the  Company  sold  10,539,374  shares  of  its  common  stock  under  the  April  2020  Sale  Agreement  for  which  the  Company  received  gross
proceeds of approximately $75,000,000, less issuance costs incurred of approximately $2,250,000 (See Note 11).

In June 2020, the Company became entitled to receive $5,000,000 upon the Company’s achievement of a milestone related to the progress of the Phase 2b Clinical Trial, as
set  forth  in  the  Cystic  Fibrosis  Program  Related  Investment  Agreement  (“Investment  Agreement”)  with  the  Cystic  Fibrosis  Foundation  (“CFF”),  a  non-profit  drug
discovery  and  development  corporation,  pursuant  to  which  the  Company  received  a  development  award  for  up  to  $25,000,000  in  funding  (the  “2018  CFF  Award”)  to
support a Phase 2b Clinical Trial (the “Phase 2b Clinical Trial”) of lenabasum in patients with cystic fibrosis. The Company received the $5,000,000 payment from the
CFF for this milestone achievement in July 2020. The Company expects the final $2.5 million remainder of the 2018 CFF Award will be paid to the Company upon the
achievement of the last remaining milestone related to the progress of the Phase 2b Clinical Trial, as set forth in the Investment Agreement. (See Note 9).

On July 28, 2020, the Company entered into the Loan Agreement with its subsidiary, Corbus Pharmaceuticals, Inc., as borrower, the Company, as guarantor, each lender
party thereto (the “Lenders”), K2 HealthVentures LLC (“K2HV”), an unrelated third party, as administrative agent for the Lenders, and Ankura Trust Company, LLC, an
unrelated third party, as collateral agent for the Lenders, pursuant to which K2HV may provide the Company with term loans in an aggregate principal amount of up to a
$50,000,000. The Company received the first $20,000,000 tranche upon signing the agreement. (See Note 7 and 14).

On August 7, 2020, the Company entered into an Open Market Sale AgreementSM (the “August 2020 Sale Agreement”) with Jefferies LLC (“Jefferies”), as sales agent,
pursuant to which the Company may issue and sell, from time to time, through Jefferies, shares of its common stock, and pursuant to which Jefferies may sell its common
stock by any method permitted by law deemed to be an “at the market offering” as defined by Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended.
The  Company  will  pay  Jefferies  a  commission  of  3.0%  of  the  aggregate  gross  proceeds  from  each  sale  of  common  stock  and  have  agreed  to  provide  Jefferies  with
customary indemnification and contribution rights. The Company has also agreed to reimburse Jefferies for certain specified expenses. As of August 7, 2020, the Company
is  authorized  to  offer  and  sell  up  to  $150 million  of  its  common  stock  pursuant  to  the  August  2020  Sale  Agreement.  During  the  year  ended  December  31,  2020,  the
Company  sold  15,546,151  shares  of  its  common  stock  under  the  August  2020  Sale  Agreement  for  which  the  Company  received  gross  proceeds  of  approximately
$21,404,000, less issuance costs incurred of approximately $642,000. The Company has sold an additional 25,391,710 shares of our common stock under the August 2020
Sale Agreement for net proceeds of approximately $58,861,000 subsequent to December 31, 2020. (See note 11 and 14)

3. SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies followed by the Company in the preparation of the financial statements is as follows:

Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and accounts have
been eliminated in consolidation.

Use of Estimates

The  process  of  preparing  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of  America  (“U.S.  GAAP”)  requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and changes in estimates may
occur.  The  most  significant  estimates  are  related  to  stock-based  compensation  expense,  the  accrual  of  research,  product  development  and  clinical  obligations,  the
recognition of revenue under the Investment Agreement (See Note 9), the valuation of the CFF and K2HV warrants discussed in Note 13 and Note 7, and the derivative
liability associated with the K2 Security and Loan agreement (see Note 14).

Cash and Cash Equivalents

The Company considers only those investments which are highly liquid, readily convertible to cash, and that mature within three months from date of purchase to be cash
equivalents. Marketable investments are those with original maturities in excess of three months. At December 31, 2020 and 2019, cash equivalents were comprised of
money market funds. The Company had no marketable investments at December 31, 2020 and 2019.

Restricted  cash  as  of  December  31,  2020  included  a  collateral  account  for  the  Company’s  corporate  credit  cards  and  is  classified  in  current  assets  in  the  amount  of
$250,000. Additionally, as of December 31, 2020, restricted cash included a stand-by letter of credit issued in favor of a landlord for $769,900 of which $100,000 was
classified in current assets and $669,900 was classified in noncurrent assets as of December 31, 2020.

As of December 31, 2020, all of the Company’s cash and cash equivalents was held in the United States, except for approximately $1,033,000 of cash which was held
principally in our subsidiary in the United Kingdom. As of December 31, 2019, all of the Company’s cash and cash equivalents was held in the United States, except for
approximately $466,000 of cash which was held principally in our subsidiary in the United Kingdom.

Financial Instruments

The carrying values of the notes payable and debt approximate their fair value due to the fact that they are at market terms.

Fair Value Measurements

The valuation of the company’s debt and embedded derivatives are determined primarily by an income approach that considers the present value of net cash flows of the
debt with and without prepayment and default features. In accordance with ASC 815 “Accounting for Derivative Instruments and Hedging Activities”,  these  embedded
debt features which are determined to be classified as derivative liabilities are marked-to-market each reporting period, with a corresponding non-cash gain or loss charged
to the current period. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an
asset or liability. As a basis for considering such assumptions, there exists a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as
follows:

Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date

Level 2 – Inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with
observable market data

Level 3 – Unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date

To  determine  the  fair  value  of  our  embedded  derivatives,  management  evaluates  assumptions  regarding  the  probability  of  certain  future  events.  Other  factors  used  to
determine fair value include the discount rate, risk free interest rate and derivative term. The fair value recorded for the derivative liability varies from period to period.
This variability may result in the actual derivative liability for a period either above or below the estimates recorded on our consolidated financial statements, resulting in
fluctuations in other income (expense) because of the corresponding non-cash gain or loss recorded.

Property and Equipment

The estimated life for the Company’s property and equipment is as follows: three years for computer hardware and software and three to five years for office furniture and
equipment. The Company’s leasehold improvements and assets under capital lease are amortized over the shorter of their useful lives or the respective leases. See Note 5
for details of property and equipment and Note 6 for operating and capital lease commitments.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
    
 
  
 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
Research and Development Expenses

Costs incurred for research and development are expensed as incurred.

F-8

 
 
 
Nonrefundable advance payments for goods or services that have the characteristics that will be used or rendered for future research and development activities pursuant to
executory  contractual  arrangements  with  third  party  research  organizations  are  deferred  and  recognized  as  an  expense  as  the  related  goods  are  delivered  or  the  related
services are performed.

Accruals for Research and Development Expenses and Clinical Trials

As part of the process of preparing its financial statements, the Company is required to estimate its expenses resulting from its obligations under contracts with vendors,
clinical research organizations and consultants and under clinical site agreements in connection with conducting clinical trials. The financial terms of these contracts are
subject to negotiations, which vary from contract to contract and may result in payment terms that do not match the periods over which materials or services are provided
under  such  contracts.  The  Company’s  objective  is  to  reflect  the  appropriate  expenses  in  its  financial  statements  by  matching  those  expenses  with  the  period  in  which
services  are  performed  and  efforts  are  expended.  The  Company  accounts  for  these  expenses  according  to  the  timing  of  various  aspects  of  the  expenses.  The  Company
determines  the  accrual  estimates  by  taking  into  account  discussion  with  applicable  personnel  and  outside  service  providers  as  to  the  progress  of  clinical  trials,  or  the
services  completed.  During  the  course  of  a  clinical  trial,  the  Company  adjusts  its  clinical  expense  recognition  if  actual  results  differ  from  its  estimates.  The  Company
makes estimates of its accrued expenses as of each balance sheet date based on the facts and circumstances known to it at that time. The Company’s clinical trial accruals
are dependent upon the timely and accurate reporting of contract research organizations and other third-party vendors. Although the Company does not expect its estimates
to be materially different from amounts actually incurred, its 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 it reporting amounts that are too high or too low for any particular period. For the years ended December 31, 2020 and 2019, there
were no material adjustments to the Company’s prior period estimates of accrued expenses for clinical trials.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities
and operating lease liabilities in the Company’s consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the
lease. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not
provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of
lease payments. This is the rate the Company would have to pay if borrowing on a collateralized basis over a similar term to each lease. The ROU asset also includes any
lease payments made and excludes lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Concentrations of Credit Risk

The Company has no significant off-balance-sheet concentration of credit risk such as foreign exchange contracts, option contracts or other hedging arrangements. The
Company may from time to time have cash in banks in excess of Federal Deposit Insurance Corporation insurance limits. However, the Company believes the risk of loss
is minimal as these banks are large financial institutions.

Segment Information

Operating  segments  are  identified  as  components  of  an  enterprise  about  which  separate  discrete  financial  information  is  available  for  evaluation  by  the  chief  operating
decision maker, or decision-making group, in making decisions regarding resource allocation and assessing performance. To date, the Company has viewed its operations
and  manages  its  business  as  principally  one  operating  segment,  which  is  developing  and  commercializing  therapeutics  to  treat  rare  life-threatening  inflammatory  and
fibrotic diseases. As of December 31, 2020, all of the Company’s assets were located in the United States, except for approximately $1,033,000 of cash, $1,837,000 of
prepaid expenses and other assets, and $23,000 of property and equipment, net which were held outside of the United States, principally in our subsidiary in the United
Kingdom. As of December 31, 2019, all of the Company’s assets were located in the United States, except for approximately $466,000 of cash, $1,629,000  of  prepaid
expenses and other assets, and $52,000 of property and equipment, net which were held outside of the United States, principally in our subsidiary in the United Kingdom.

Income Taxes

For federal and state income taxes, deferred tax assets and liabilities are recognized based upon temporary differences between the financial statement and the tax basis of
assets  and  liabilities.  Deferred  income  taxes  are  based  upon  prescribed  rates  and  enacted  laws  applicable  to  periods  in  which  differences  are  expected  to  reverse.  A
valuation allowance is recorded to reduce a net deferred tax benefit when it is not more likely than not that the tax benefit from the deferred tax assets will be realized.
Accordingly, given the cumulative losses since inception, the Company has provided a valuation allowance equal to 100% of the deferred tax assets in order to eliminate
the deferred tax assets amounts.

Tax positions taken or expected to be taken in the course of preparing the Company’s tax returns are required to be evaluated to determine whether the tax positions are
“more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet a more-likely-than-not threshold, as well as accrued interest
and  penalties,  if  any,  would  be  recorded  as  a  tax  expense  in  the  current  year.  There  were  no  uncertain  tax  positions  that  require  accrual  or  disclosure  to  the  financial
statements as of December 31, 2020 or 2019.

Impairment of Long-lived Assets

The  Company  continually  monitors  events  and  changes  in  circumstances  that  could  indicate  that  carrying  amounts  of  long-lived  assets  may  not  be  recoverable.  An
impairment loss is recognized when expected undiscounted cash flows of an asset are less than an asset’s carrying value. Accordingly, when indicators of impairment are
present, the Company evaluates the carrying value of such assets in relation to the operating performance and future undiscounted cash flows of the underlying assets. An
impairment loss equal to the excess of the fair value of the asset over its carrying amount, is recorded when it is determined that the carrying value of the asset may not be
recoverable. No impairment charges were recorded for the years ended December 31, 2020 and 2019.

Stock-based Payments

The Company recognizes compensation costs resulting from the issuance of stock-based awards to employees, non-employees and directors as an expense in the statement
of operations over the service period based on a measurement of fair value for each stock-based award. The fair value of each option grant to employees is estimated as of
the date of grant using the Black-Scholes option-pricing model, net of estimated forfeitures. The fair value is amortized as compensation cost on a straight-line basis over
the requisite service period of the awards, which is generally the vesting period.

Foreign Currency

Transaction gains and losses arising from currency exchange rate fluctuations on transactions denominated in a currency other than the U.S. Dollar functional currency are
recorded in the Company’s statement of operations. Such transaction gains and losses may be realized or unrealized depending upon whether the transaction settled during
the period or remains outstanding at the balance sheet date.

Net Loss Per Common Share

Basic and diluted net loss per share of the Company’s common stock has been computed by dividing net loss by the weighted average number of shares outstanding during
the period. For years in which there is a net loss, options and warrants are anti-dilutive and therefore excluded from diluted loss per share calculations. The following table
sets forth the computation of basic and diluted earnings per share for the years ended December 31, 2020 and 2019:

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 (“ASU 2018-
18”). ASU 2018-18 clarifies the interaction between the accounting guidance for collaborative arrangements and revenue from contracts with customers. ASU 2018-18 is
effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. The Company’s adoption of ASU
2018-18 as of January 1, 2019 had no impact on the Company’s financial statements and related disclosures.

Accounting for Income Taxes

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes which is intended to simplify various aspects
related to accounting for income taxes. The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2020, with early
adoption permitted. The standard will be adopted upon the effective date for us beginning January 1, 2021. The Company’s adoption of ASU 2019-12 as of January 1, 2021
will not have a material impact on the Company’s financial statements and related disclosures.

Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s
Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity which is intended to simplify various aspects generally
accepted accounting principles (GAAP) for certain financial instruments with characteristics of liabilities and equity. The standard is effective for public companies that
meet definition of a Securities and Exchange Commission (SEC) filer, excluding entities to be smaller reporting companies as defined by the SEC, for fiscal years, and
interim periods within those years, beginning after December 15, 2021. For all other entities, the amendments are effective for fiscal years beginning after December 15,
2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim
periods within those fiscal years. The Company is currently evaluating the timing of the adoption of ASU 2020-06 and the expected impact it could have on the Company’s
financial statements and related disclosures.

4. LICENSE AGREEMENT

The Company entered into a License Agreement (the “Jenrin Agreement”) with Jenrin Discovery, LLC, a privately-held Delaware limited liability company (“Jenrin”),
effective  September  20,  2018.  Pursuant  to  the  Jenrin  Agreement,  Jenrin  granted  the  Company  exclusive  worldwide  rights  to  develop  and  commercialize  the  Licensed
Products (as defined in the Jenrin Agreement) which includes the Jenrin library of over 600 compounds and multiple issued and pending patent filings. The compounds are
designed to treat inflammatory and fibrotic diseases by targeting the endocannabinoid system.

In consideration of the license and other rights granted by Jenrin, the Company paid Jenrin a $250,000 upfront cash payment and is obligated to pay potential milestone
payments to Jenrin totaling up to $18.4 million for each compound it elects to develop based upon the achievement of specified development and regulatory milestones. In
addition, Corbus is obligated to pay Jenrin royalties in the mid, single digits based on net sales of any Licensed Products, subject to specified reductions.

In  January  2017,  the  FASB  issued  ASU  2017-01,  Business  Combinations  (Topic  805):  Clarifying  the  Definition  of  a  Business  (“ASU  2017-01”)  which  clarifies  the
definition of a business and determines when an integrated set of assets and activities is not a business. ASU 2017-01 requires that if substantially all of the fair value of
gross  assets  acquired  or  disposed  of  is  concentrated  in  a  single  asset  or  group  of  similar  identifiable  assets,  the  assets  would  not  represent  a  business.  The  Company
determined that substantially all of the fair value of the Jenrin Agreement was attributable to a single in-process research and development asset which did not constitute a
business. The Company concluded that it did not have any alternative future use for the acquired in-process research and development asset. Thus, the Company recorded
the $250,000 upfront payment to research and development expenses in the third quarter of 2018. The Company will account for the $18.4 million of development and
regulatory milestone payments in the period that the relevant milestones are achieved as either research and development expense or as an intangible asset as applicable.

6. COMMITMENTS AND CONTINGENCIES

Operating Lease Commitment

On August 21, 2017, the Company entered into a lease agreement (“August 2017 Lease Agreement”) for commercial lease of office space, pursuant to which the Company
agreed to lease 32,733 square feet of office space (“Leased Premises”). The initial term of the August 2017 Lease Agreement was for a period of seven years which began
with the Company’s occupancy of the Leased Premises in February 2018. The base rent for the Leased Premises ranged from approximately $470,000 for the first year to
approximately $908,000  for  the  seventh  year.  Per  the  terms  of  the  August  2017  Lease  Agreement,  the  landlord  agreed  to  reimburse  the  Company  for  approximately
$1,080,000  of  leasehold  improvements.  The  reimbursements  had  been  deferred  and  were  to  be  recognized  as  a  reduction  of  rent  expense  over  the  term  of  the  lease.
Additionally, the August 2017 Lease Agreement required a standby irrevocable letter of credit of $400,000, which was to be reduced, if the Company is not in default
under the August 2017 Lease Agreement, to $300,000 and $200,000 on the third and fourth anniversary of the commencement date, respectively, The Company entered
into an unsecured letter of credit for $400,000 in connection with the August 2017 Lease Agreement.

The  Company  adopted  ASU  2016-02,  Leases  (Topic  842),  as  amended  (“ASU  2016-02”)  using  the  effective  date  method  as  of  January  1,  2019  and  recorded  a  lease
liability of approximately $3,811,000, and a right-of-use asset of approximately $2,400,000, with no operations adjustment to the accumulated deficit related to the Leased
Premises. Operating leases are included in operating lease right-of-use assets (“ROU”), operating lease liabilities, current and operating lease liabilities, noncurrent in the
Company’s consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the
lease. ROU assets and liabilities are recognized at the date of adoption based on the present value of lease payments over the lease term. As the Company’s leases do not
provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of
lease payments, which was 9%. This is the rate the Company would have to pay if borrowing on a collateralized basis over a similar term to each lease. The ROU asset
also includes any lease payments made and excludes lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

On February 26, 2019, the Company amended its lease (“February 2019 Lease Agreement”) pursuant to which an additional 30,023 square feet of office space (“New
Premises”) will be leased by the Company in the same building for an aggregate total of 62,756 square feet of leased office space (“Total Premises”). The February 2019
Lease Agreement constitutes a modification as it extends the original lease term and increases the scope of the lease (additional space provided under the amendment),
which requires evaluation of the remeasurement of the lease liability and corresponding ROU asset. Accordingly, the Company reassessed the classification of the Leased
Premises and remeasured the lease liability on the basis of the extended lease term using the 20 additional monthly rent payments and the incremental borrowing rate at the
effective  date  of  the  modification  of  9%.  The  remeasurement  for  the  modification  resulted  in  an  increase  to  the  lease  liability  and  the  ROU  asset  of  approximately
$855,000. The Company determined that the New Premises will be treated as a new standalone operating lease and recorded a lease liability and a right-of-use asset of
approximately $2,700,000 for this lease.

Per  the  terms  of  the  February  2019  Lease  Agreement,  the  landlord  agreed  to  reimburse  the  Company  for  approximately  $991,000  of  leasehold  improvements.  The
reimbursements  are  being  recognized  as  a  reduction  of  rent  expense  over  the  term  of  the  lease.  Additionally,  the  February  2019  Lease  Agreement  required  a  standby
irrevocable letter of credit of $369,900, which may be reduced, if the Company is not in default under the February 2019 Lease Agreement, to $277,425 and $184,950 on
the third and fourth anniversary of the commencement date, respectively.

On October 25, 2019, the Company amended its lease (“October 2019 Lease Amendment”) pursuant to which the term of the lease was extended through November 30,
2026  and  the  existing  office  space  under  lease  was  expanded  by  500  square  feet  for  an  aggregate  total  of  63,256  square  feet  of  leased  office  space  (“Amended  Total
Premises”). The  October  2019  Lease  Amendment  constitutes  a  modification  as  it  extends  the  original  lease  term  and  increases  the  scope  of  the  lease  (additional  space
provided under the amendment), which requires evaluation of the remeasurement of the lease liability and corresponding ROU asset. The additional space did not result in
a  separate  contract  as  the  rent  increase  was  determined  not  to  be  commensurate  with  the  standalone  price  for  the  additional  right  of  use.  Accordingly,  the  Company
reassessed the classification of the Amended Total Premises, which resulted in operating classification, and remeasured the lease liability on the basis of the extended lease
term  using  the  additional  monthly  rent  payments  and  the  incremental  borrowing  rate  at  the  effective  date  of  the  modification  of  8%.  The  remeasurement  for  the
modification resulted in an increase to the lease liability and the ROU asset of approximately $381,000 that was recorded in the fourth quarter of 2019.

7. NOTES PAYABLE

D&O Financing

In November 2019, the Company entered into a loan agreement with a financing company for $963,514 to finance one of the Company’s insurance policies. The terms of
the loan stipulated equal monthly payments of principal and interest payments of $109,413 over a nine-month period. Interest accrued on this loan at an annual rate of
5.25%. This loan was fully repaid in July 2020.

In November 2020, the Company entered into a loan agreement with a financing company for $909,375 to finance one of the Company’s insurance policies. The terms of
the  loan  stipulate  equal  monthly  payments  of  principal  and  interest  payments  of  $103,112 over a nine-month period.  Interest  accrues  on  this  loan  at  an  annual  rate  of
4.89%. Prepaid expenses as of December 31, 2020 included approximately $1,010,000, related to this insurance policy.

Loan and Security Agreement with K2 HealthVentures LLC

On July 28, 2020, the Company, with its subsidiary, Corbus Pharmaceuticals, Inc., as borrower, entered into a $50,000,000 secured Loan and Security Agreement with
K2HV, an unrelated third party (the “Loan Agreement”) and received the first $20,000,000 tranche upon signing. The second tranche of $20,000,000 and the third tranche
of $10,000,000 will be made available at the Company’s option subject to the achievement of certain clinical and regulatory milestones. The loan matures on August 1,
2024 and the Company is obligated to make interest only payments for the first 24 months and then interest and equal principal payments for the next 24 months. Interest
accrues at a variable annual rate equal to the greater of (i) 8.5% and (ii) the rate of interest noted in The Wall Street Journal, Money Rates section, as the “Prime Rate” plus
5.25%, in each case, subject to a step-down of 25 basis points upon the funding of the second tranche. The interest rate used at December 31, 2020 was 8.5%. K2HV may
elect to convert up to $5,000,000 of the outstanding loan into common stock at a conversion price of $9.40 per share.

In connection with the Loan Agreement, on July 28, 2020, the Company issued the Lenders a warrant to purchase up to 86,206 common shares (the “K2 Warrant”) at an
exercise price of $6.96 (the “Warrant Price”). The K2 Warrant may be exercised either for cash or on a cashless “net exercise” basis and expires on July 28, 2030. The total
proceeds attributed to the K2 Warrant was approximately $472,000 based on the relative fair value of the K2 Warrant as compared to the sum of the fair values of the K2
Warrant, prepayment feature, default feature, and debt. Total proceeds attributed to the prepayment and default features was approximately $546,000. The Company also
incurred approximately $1,244,000  of  debt  issuance  costs  and  is  required  to  make  a  final  payment  equal  to  approximately  $1,190,000.  See  Note  13  for  more  detail  on
assumptions used in the valuation of the K2 warrant and see Note 14 for more information on the assumptions used in valuation of the default and prepayment features.

The  total  principal  amount  of  the  loan  under  the  Loan  Agreement  outstanding  at  December  31,  2020,  including  the  $1,190,000  final  payment  discussed  above,  is
$21,190,000.

Upon  the  occurrence  of  an  Event  of  Default  (as  defined  in  the  Loan  Agreement),  and  during  the  continuance  of  an  Event  of  Default,  the  applicable  rate  of  interest,
described above, will be increased by 5.00% per annum. The secured term loan maturity date is August 1, 2024, and the Loan Agreement includes both financial and non-
financial covenants. The Company was in compliance with these covenants as of December 31, 2020. The obligations under the Loan Agreement are secured on a senior
basis by a lien on substantially all of the assets of the Company and its subsidiaries. The subsidiaries of the Company are guarantors of the obligations of the Company
under the Loan Agreement.

The total debt discount related to Lenders of approximately $2,262,000 is being charged to interest expense using the effective interest method over the term of the debt. At
December 31, 2020, the fair value of our outstanding debt, which is considered Level 3 in the fair value hierarchy, is estimated to be approximately $18,029,005. Interest
expense for the year ended December 31, 2020 was approximately $1,126,534. No interest expense or amortization of debt discount recorded in 2019 related to the Loan
Agreement.

under  the  laws  of  Japan  (“Kaken”).  Pursuant  to  the  Agreement,  Corbus  granted  Kaken  an  exclusive  license  to  commercialize  pharmaceutical  preparations  containing
lenabasum  (the  “Licensed  Products”)  for  the  prevention  or  treatment  of  dermatomyositis  and  systemic  sclerosis  (together,  the  “Initial  Indications”)  in  Japan  (the
“Territory”).

Pursuant to the terms of the Agreement, Corbus will bear the cost of, and be responsible for, among other things, conducting the clinical studies and other developmental
activities for the Licensed Products in the Initial Indications in the Territory, and Kaken will bear the cost of, and be responsible for, among other things, preparing and
filing  applications  for  regulatory  approval  in  the Territory  and  for  commercializing  Licensed  Products  in  the  Territory,  and  will  use  commercially  reasonable  efforts  to
commercialize Licensed Products and obtain pricing approval for Licensed Products in the Territory.

In  consideration  of  the  license  and  other  rights  granted  by  Corbus,  Kaken  paid  to  Corbus  in  March  2019  a  $27,000,000  upfront  cash  payment  and  is  obligated  to  pay
potential milestone payments to Corbus totaling up to approximately $173,000,000 for the achievement of certain development, sales and regulatory milestones, with part
of the milestone payments being calculated in Japanese Yen, and therefore subject to change based on the conversion rate to U.S. Dollars in effect at the time of payment.
In addition, during the Royalty Term (as defined below), Kaken is obligated to pay Corbus royalties on sales of Licensed Products in the Territory, under certain conditions,
in the double digits, which royalty shall be reduced in certain circumstances. In particular, for so long as Corbus supplies Licensed Products to Kaken pursuant to a supply
agreement  to  be  entered  into  by  the  parties,  royalty  payments  shall  be  payable  for  each  unit  of  Licensed  Product  that  Corbus  supplies  as  a  percentage  of  the  Japanese
National Health Insurance price of the Licensed Product. During any time in which a supply agreement is not in effect, royalty payments shall be changed to a rate to be
agreed upon by the parties in good faith.

The Agreement  will  remain  in  effect  on  a  Licensed  Product-by-Licensed  product  basis  and  will  expire  upon  the  expiration  of  the  Royalty Term  for  the  final  Licensed
Product. The  “Royalty  Term”  means  the  period  beginning  on  the  date  of  the  first  commercial  sale  of  the  Licensed  Product  in  Japan  and  ends  on  the  latest  of  (i)  the
expiration of the last valid claim of the royalty patents covering such Licensed Product in Japan, (ii) the expiration of regulatory exclusivity for such Licensed Product for
such Initial Indication in Japan, or (iii) ten (10) years after the first commercial sale of such Licensed Product for such Initial Indication in Japan. The Agreement may be
terminated by either party for material breach, upon a party’s insolvency or bankruptcy or upon a challenge by one party of any patents of the other party, and Kaken may
terminate in specified situations, including for a safety concern or clinical failure, or at its convenience following the second anniversary of the first commercial sale of a
Licensed Product in either of the Initial Indications in the Territory, with 180 days’ notice.

Pursuant to the Agreement, the parties agreed to develop a joint steering committee to provide strategic oversight of the parties’ activities under the Agreement, as well as a
joint development committee to coordinate the development of Licensed Products in Japan. Additionally, the parties will establish a joint commercialization committee to
review and confirm commercialization activities with respect to Licensed Products in Japan upon regulatory approval of such Licensed Product.

The  Agreement  also  contains  customary  representations,  warranties  and  covenants  by  both  parties,  as  well  as  customary  provisions  relating  to  indemnification,
confidentiality and other matters.

The Company assessed this arrangement in accordance with U.S. GAAP and concluded that the contract counterparty, Kaken, is a customer. The Company identified the
following material promises under the arrangement: (1) the exclusive license to commercialize lenabasum; (2) the product’s initial know-how transfer; (3) election to use
the product trademarks; (4) the sharing of data gathered through the execution of the Global Development Plan for the Initial Indications; and (5) Japanese Pharmaceuticals
and Medical Devices Agency (“PMDA”)-required supplemental studies. The Company identified two performance obligations; (1) the combined performance obligation
of  the  License,  initial  know-how  transfer  and  license  to  the  Company’s  product  trademarks;  and  (2)  the  sharing  of  data  gathered  through  the  execution  of  the  Global
Development Plan (as defined in the Agreement) for the Initial Indications. The Company determined that the license and initial know-how transfer were not distinct from
another in the context of the contract, as initial know-how transfer is highly interrelated to the license and Kaken would incur significant costs to re-create the know-how of
the Company. The Company determined that the election to use the product trademarks license contributes to the exclusivity of the license and, therefore, is combined with
the license. The PMDA-required supplemental study is a contingent promise although not a performance obligation as the promise does not provide Kaken with a material
right.

Under the Agreement, in order to evaluate the appropriate transaction price, the Company determined that the upfront amount of $27,000,000 constituted the entirety of the
consideration to be included in the transaction price at the outset of the arrangement, which was allocated to the two performance obligations. The potential milestone
payments that the Company is eligible to receive were excluded from the transaction price, as all milestone payments are fully constrained based on the probability of
achievement. The Company will reevaluate the transaction price at the end of each reporting period and as uncertain events are resolved or other changes in circumstances
occur, and, if necessary, adjust its estimate of the transaction price.

The Company estimated the stand-alone selling price of each performance obligation using a market approach and allocated the transaction price on a relative basis. This
allocation resulted in a de minimis value attributable to the obligation to sharing of data gathered through the execution of the Global Development Plan for the Initial
Indications and effectively all of the value to the combined license, initial know-how transfer and license to product trademarks. Therefore, the full upfront payment of
$27,000,000 is allocated to the combined performance obligation of the license, initial technology transfer and license to the product trademarks.

The  Company  received  the  upfront  payment  of  $27,000,000  in  March  2019  and,  as  the  performance  obligations  were  not  yet  satisfied  at  that  time,  the  payment  was
recorded in deferred revenue as of March 31, 2019. The Company satisfied the combined performance obligation by June 30, 2019, upon which the Company recognized
the $27,000,000 upfront payment as revenue in the second quarter of 2019.

The Company was required to make a $2,700,000 royalty payment to CFF within 60 days of receipt of the upfront cash payment from Kaken pursuant to the 2018 CFF
Award. This obligation was paid by the Company to CFF in May 2019.

2018 CFF Award

On January 26, 2018, the Company entered into the Cystic Fibrosis Program Related Investment Agreement with the CFF (“Investment Agreement”), a non-profit drug
discovery and development corporation, pursuant to which the Company received an award for up to $25 million in funding (the “2018 CFF Award”) to support a Phase 2b
Clinical  Trial  (the  “Phase  2b  Clinical  Trial”)  of  lenabasum  in  patients  with  cystic  fibrosis,  of  which  the  Company  has  received  $22.5 million  in  the  aggregate  through
December 31, 2020 upon the Company’s achievement of milestones related to the progress of the Phase 2b Clinical Trial, as set forth in the Investment Agreement. The
Company expects that the $2.5 million remainder of the 2018 CFF Award will be paid upon the Company’s achievement of the final milestone related to the progress of the
Phase 2b Clinical Trial, as set forth in the Investment Agreement, and the Company expects to receive the remainder before the end of the first half of 2021.

Pursuant to the terms of the Investment Agreement, the Company is obligated to make certain royalty payments to CFF, including a royalty payment of one and one-half
times the amount of the 2018 CFF Award, payable in cash within sixty days upon the first receipt of approval of lenabasum in the United States and a second royalty
payment of one and one-half times the amount of the 2018 CFF Award upon approval in another major market, as set forth in the Investment Agreement (the “Approval
Royalty”). At the Company’s election, the Company may satisfy the first of the two Approval Royalties in registered shares of the Company’s common stock.

F-17

 
 
 
 
 
 
 
 
 
 
Additionally,  the  Company  is  obligated  to  make  (i)  royalty  payments  to  CFF  of  two  and  one-half  percent  of  net  sales  from  lenabasum  due  within  sixty  days  after  any
quarter in which such net sales occur in the Field, as defined in the Investment Agreement, (ii) royalty payments to CFF of one percent of net sales of Non-Field Products,
as defined in the Investment Agreement due within sixty days after any quarter in which such net sales occur, and (iii) royalty payments to CFF of ten percent of any
amount  the  Company  and  its  stockholders  receive  in  connection  with  the  license,  sale,  or  other  transfer  to  a  third  party  of  lenabasum,  if  indicated  for  the  treatment  or
prevention of CF, or a change of control transaction, except that such payment shall not exceed five times the amount of the 2018 CFF Award, with such payments to be
credited  against  any  other  net  sales  royalty  payments  due.  Accordingly,  the  Company  will  owe  to  CFF  a  royalty  payment  equal  to  10%  of  any  amounts  the  Company
receives  as  payment  under  the  collaboration  agreement  with  Kaken,  provided  that  the  total  royalties  that  the  Company  will  be  required  to  pay  under  the  Investment
Agreement resulting from income from licenses or sales subject to the Investment Agreement are capped at five times the total amount of the 2018 CFF Award, and the
Company may credit such royalties against any royalties on net sales otherwise owed to CFF under the Investment Agreement. Accordingly, the Company was required to
pay CFF $2,700,000 in May 2019 as a result of its receipt of the $27,000,000 upfront cash payment from Kaken.

Either CFF or the Company may terminate the Investment Agreement for cause, which includes the Company’s material failure to achieve certain commercialization and
development milestones. The Company’s payment obligations survive the termination of the Investment Agreement.

Pursuant to the terms of the Investment Agreement, the Company issued a warrant to CFF to purchase an aggregate of 1,000,000 shares of the Company’s common stock
(the “CFF Warrant”). The CFF Warrant is exercisable at a price equal to $13.20 per share and is immediately exercisable for 500,000 shares of the Company’s common
stock. Upon completion of the final milestone set forth in the Investment Agreement and receipt of the final payment from CFF to the Company pursuant to the Investment
Agreement, the CFF Warrant will be exercisable for the remaining 500,000 shares of the Company’s common stock. The CFF Warrant expires on January 26, 2025. Any
shares of the Company’s common stock issued upon exercise of the CFF Warrant will be unregistered and subject to a one-year lock-up.

Under  the  Investment  Agreement,  the  Company  recorded  $3,937,230  and  $9,143,568  of  revenue  during  the  year  ended  December  31,  2020  and  2019.  The  Company
assessed the 2018 CFF Award for accounting under ASC 606, which it adopted in the first quarter of 2018. To determine revenue recognition for arrangements that an
entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance
obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue
when (or as) the entity satisfies a performance obligation.

The  Company  assessed  this  arrangement  in  accordance  with  ASC  606  and  concluded  that  the  contract  counterparty,  CFF,  is  a  customer.  The  Company  identified  the
following material promise under the arrangement: research and development activities and related services under the Phase 2b Clinical Trial. Based on these assessments,
the  Company  identified  one  performance  obligation  at  the  outset  of  the  Investment  Agreement,  which  consists  of:  Phase  2b  Clinical  Trial  research  and  development
activities and related services.

To determine the transaction price, the Company included the total aggregate payments under the Investment Agreement which amount to $25 million and reduced the
revenue to be recognized by the payment to the customer of $6,215,225 in the form of the CFF Warrant representing its fair value, leaving the remaining $18,784,775 as
the transaction price as of the outset of the arrangement, which will be recognized as revenue over the performance period as discussed below. The $6,215,225 fair value of
the warrant was also recorded as an increase to additional paid in capital.

The Company has invoiced and received $22,500,000 so far in milestone payments including $12,500,000 in 2018, $5,000,000 in 2019 and $5,000,000 in 2020. A roll
forward of deferred revenue related to the Investment Agreement for the year ended December 31, 2020 is presented below.

The CFF Warrant is accounted for as a payment to the customer. See Note 13 for further information related to the CFF Warrant. The Company notes that the Investment
Agreement  contains  an  initial  payment  that  was  received  upon  contract  execution  and  subsequent  milestone  payments,  which  are  a  form  of  variable  consideration  that
require evaluation for constraint considerations. The Company concluded that the related performance milestones are generally within the Company’s control and as result
are considered probable. Revenue associated with the performance obligation is being recognized as revenue as the research and development services are provided using
an input method, according to the costs incurred as related to the research and development activities on each program and the costs expected to be incurred in the future to
satisfy the performance obligation. The transfer of control occurs over this time period and, in management’s judgment, is the best measure of progress towards satisfying
the performance obligation. The research and development services related to this performance obligation are expected to be performed over approximately three years and
is expected to be completed in the first half of 2021. The amounts received that have not yet been recognized as revenue are recorded in deferred revenue and the amounts
recognized as revenue, but not yet received or invoiced are generally recognized as a contract asset on the Company’s condensed consolidated balance sheet.

10. INCOME TAXES

No provision or benefit for federal or state income taxes has been recorded, as the Company has incurred a net loss for all of the periods presented, and the Company has
provided a full valuation allowance against its deferred tax assets.

At  December  31,  2020  and  2019,  the  Company  had  federal  net  operating  loss  carryforwards  of  approximately  $167,399,000 and  $99,754,000,  respectively,  of  which
federal carryforwards will expire in varying amounts beginning in 2029. Of the federal net operating loss carryforwards of $167,399,000, approximately $111,047,000 are
from 2018, 2019, and 2020 have no expiration date, and are limited to 80% of taxable income. At December 31, 2020 and 2019, the Company had Massachusetts net
operating  loss  carryforwards  of  approximately  $161,143,000  and  $94,884,000,  respectively.  Utilization  of  net  operating  losses  may  be  subject  to  substantial  annual
limitations due to the “change in ownership” provisions of the Internal Revenue Code, and similar state provisions. The annual limitations may result in the expiration of
net operating losses before utilization. The Company has not yet conducted a study to determine if any such changes have occurred that could limit the Company’s ability
to use the net operating losses and tax credit carryforwards. The Company also had research and development tax credit carryforwards at December 31, 2020 and 2019 of
approximately $9,233,000 and $6,031,000, respectively.

In the second half of 2020, the Company received from a foreign taxing authority, an approximate aggregate $13.7 million of cash payments for refundable research and
development tax credits that were earned on certain research and development expenses. The Company recorded the $13.7 million in other income in the accompanying
statements of operations for the year ended December 31, 2020.

Significant components of the Company’s net deferred tax asset are as follows:

NOL carryforward
Foreign net operating loss carryforward
Tax credits
Stock based compensation
Accrued expenses
Other temporary differences
Subtotal
Valuation allowance

The Company has maintained a full valuation allowance against its deferred tax assets in all periods presented. A valuation allowance is required to be recorded when it is
not more likely than not that some portion or all of the net deferred tax assets will be realized. Since the Company cannot determine that it is more likely than not that it
will  generate  taxable  income,  and  thereby  realize  the  net  deferred  tax  assets,  a  full  valuation  allowance  has  been  provided.  The  valuation  allowance  increased  by
$23,324,000 and $18,210,000 in 2020 and 2019, respectively, due to the increase in deferred tax assets, primarily due to net operating loss carryforwards. The Company
has no uncertain tax positions at December 31, 2020 and 2019 that would affect its effective tax rate. Since the Company is in a loss carryforward position, the Company is
generally subject to U.S. federal and state income tax examinations by tax authorities for all years for which a loss carryforward is available.

shares of the Company’s common stock through an “at the market offering.” As of August 7, 2020, the company was authorized to sell up to $150,000,000 of shares of the
Company’s  common  stock  pursuant  to  the  August  2020  Sale  Agreement.  During  the  year  ended  December  31,  2020.  During  the  year  ended  December  31,  2020,  the
Company  sold  15,546,151  shares  of  its  common  stock  under  the  August  2020  Sale  Agreement  for  which  the  Company  received  gross  proceeds  of  approximately
$21,404,000, less issuance costs incurred of approximately $642,000 through December 31, 2020.

During the year ended December 31, 2020 and 2019, the Company issued 427,611 and 107,029 shares of common stock upon the exercise of stock options to purchase
common stock and the Company received proceeds of approximately $756,000 and $387,000 from these exercises, respectively.

No warrants were exercised during the year ended December 31, 2020. During the year ended December 31, 2019, warrants to purchase 1,283,500 shares of stock were
exercised on a cashless basis resulting in the issuance of 1,119,868 shares of common stock.

12. STOCK OPTIONS

In April 2014, the Company adopted the Corbus Pharmaceuticals Holdings, Inc. 2014 Equity Incentive Plan (the “2014 Plan”). Pursuant to the 2014 Plan, the Company’s
Board of Directors may grant incentive and nonqualified stock options and restricted stock to employees, officers, directors, consultants and advisors. Pursuant to the terms
of  an  annual  evergreen  provision  in  the  2014  Plan,  the  number  of  shares  of  common  stock  available  for  issuance  under  the  2014  Plan  shall  automatically  increase  on
January 1 of each year by at least seven percent (7%) of the total number of shares of common stock outstanding on December 31st of the preceding calendar year, or,
pursuant to the terms of the 2014 Plan, in any year, the Board of Directors may determine that such increase will provide for a lesser number of shares. On January 1, 2020,
pursuant to an annual evergreen provision contained in the 2014 Plan, the number of shares reserved for future grants was increased by 4,527,103 shares, which was seven
percent (7%) of the outstanding shares of common stock on December 31, 2019. As of December 31, 2020, there was a total of 23,070,842 shares reserved for issuance
under the 2014 Plan and there were 7,369,051 shares available for future grants. Options issued under the 2014 Plan generally vest over 4 years from the date of grant in
multiple tranches and are exercisable for up to 10 years from the date of issuance.

In accordance with the terms of the 2014 Plan, effective as of January 1, 2021, the number of shares of common stock available for issuance under the 2014 Plan increased
by 2,500,000 shares, which was less than seven percent (7%) of the outstanding shares of common stock on December 31, 2020 (see Note 15). As of January 1, 2021, the
2014 Plan had a total reserve of 25,570,842 shares and there were 9,869,051 shares available for future grants.

Share-based Compensation

For  stock  options  issued  and  outstanding  for  the  years  ended  December  31,  2020  and  2019,  the  Company  recorded  non-cash,  stock-based  compensation  expense  of
$12,458,229 and $11,981,655, respectively, net of estimated forfeitures.

The fair value of each option award for employees is estimated on the date of grant and for non-employees is estimated at the end of each reporting period until vested
using  the  Black-Scholes  option  pricing  model  that  uses  the  assumptions  noted  in  the  following  table.  The  Company  uses  historical  data,  as  well  as  subsequent  events
occurring prior to the issuance of the financial statements, to estimate option exercises and employee terminations in order to estimate its forfeiture rate. The expected term
of options granted under the 2014 Plan, all of which qualify as “plain vanilla” per SEC Staff Accounting Bulletin 107, is determined based on the simplified method due to
the  Company’s  limited  operating  history,  and  is  6.25  years  based  on  the  average  between  the  vesting  period  and  the  contractual  life  of  the  option.  For  non-employee
options, the expected term is the contractual term. The risk-free rate is based on the yield of a U.S. Treasury security with a term consistent with the option.

The weighted average assumptions used principally in determining the fair value of options granted were as follows:

Risk free interest rate
Expected dividend yield
Expected term in years
Expected volatility
Estimated forfeiture rate

13. WARRANTS

No warrants were exercised during the year ended December 31, 2020. During the year ended December 31, 2019, warrants to purchase 1,283,500 shares of stock were
exercised on a cashless basis resulting in the issuance of 1,119,868 shares of common stock.

At December 31, 2020, there were warrants outstanding to purchase 1,506,206 shares of common stock with a weighted average exercise price of $9.46 and a weighted
average remaining life of 4.6 years, related to the warrants issued to CFF pursuant to the terms of the Investment Agreement (Note 9) warrants issued to a consultant for
investor relations services and the warrants issued pursuant to the K2 Loan and Security Agreement (Note 7).

The  Company  issued  a  warrant  to  CFF  to  purchase  an  aggregate  of  1,000,000  shares  of  the  Company’s  common  stock  (the  “CFF  Warrant”).  The  CFF  Warrant  is
exercisable at a price equal to $13.20 per share and is immediately exercisable for 500,000 shares of the Company’s common stock. Upon completion of the final milestone
set  forth  in  the  Investment  Agreement  and  receipt  of  the  final  payment  from  CFF  to  the  Company  pursuant  to  the  Investment  Agreement,  the  CFF  Warrant  will  be
exercisable for the remaining 500,000 shares of the Company’s common stock. The CFF Warrant expires on January 26, 2025. Any shares of the Company’s common
stock issued upon exercise of the CFF Warrant will be unregistered and subject to a one-year lock-up. The CFF Warrant is classified as equity as it meets all the conditions
under  U.S.  GAAP  for  equity  classification.  In  accordance  with  U.S.  GAAP,  the  Company  has  calculated  the  fair  value  of  the  warrant  for  initial  measurement  and  will
reassess whether equity classification for the warrant is appropriate upon any changes to the warrants or capital structure, at each balance sheet date. The weighted average
assumptions used in determining the $6,215,225 fair value of the CFF Warrant were as follows:

Risk free interest rate
Expected dividend yield
Expected term in years
Expected volatility

On  July  28,  2020,  the  Company  entered  into  the  Loan  Agreement  with  K2HV  pursuant  to  which  K2HV  may  provide  the  Company  with  term  loans  in  an  aggregate
principal amount of up to $50,000,000. On July 28, 2020, in connection with the funding of the first $20,000,000 tranche, the Company issued a warrant exercisable for
86,206 shares of the Company’s common stock (the “K2 Warrant”) at an exercise price of $6.96 per share. The K2 warrant is immediately exercisable for 86,206 shares
and expires on July 28, 2030. Any shares of the Company’s common stock issued upon exercise of the K2 Warrant are permitted to be settled in unregistered shares. The
K2 Warrant is classified as equity as it meets all the conditions under U.S. GAAP for equity classification. In accordance with U.S. GAAP, the Company has calculated the
fair value of the warrant for initial measurement and will reassess whether equity classification for the warrant is appropriate upon any changes to the warrants or capital
structure, at each balance sheet date. The weighted average assumptions used in determining the $472,409 fair value of the K2 Warrant were as follows:

Risk free interest rate
Expected dividend yield
Expected term in years
Expected volatility

On October 16, 2020, the Company entered into a professional services agreement with an investor relations service provider. Pursuant to the agreement, the Company
issued warrants exercisable for a total of 420,000 shares of the Company’s common stock (the “Warrants”) at an exercise price of $1.07 per share. The Warrants will be
fully vested on October 19, 2021. Any shares of the Company’s common stock issued upon exercise of the Warrants are permitted to be settled in unregistered shares. The
Warrants are classified as equity as they meet all the conditions under U.S. GAAP for equity classification. In accordance with U.S. GAAP, the Company has calculated the
fair  value  of  the  warrants  for  initial  measurement  and  will  reassess  whether  classification  for  the  warrant  is  appropriate  upon  any  changes  to  the  warrants  or  capital
structure, at each balance sheet date. The weighted average assumptions used in determining the $334,740 fair value of the Warrants were as follows:

Risk free interest rate
Expected dividend yield
Expected term in years

14. DERIVATIVE LIABILITY

100.6%

On July 28, 2020, the Company, with its subsidiary, Corbus Pharmaceuticals, Inc., as borrower, entered into a $50,000,000 secured Loan and Security Agreement with
K2HV, an unrelated third party (the “Loan Agreement”) and received the first $20,000,000 tranche upon signing. The Company has determined that a prepayment feature
and default feature needed to be separately valued and mark to market each reporting period after assessing the agreement under ASC 815.

The value of these features are determined each reporting period by taking the present value of net cash flows with and without the prepayment features. The significant
assumption used to determine the fair value of the debt without any features is the discount rate which has been estimated by using published market rates of triple CCC
rated  public  companies.  All  other  inputs  are  taken  from  the  Loan  Agreement.  The  additional  significant  assumptions  used  when  valuing  the  prepayment  feature  is  the
probability of a change of control event. The Company has determined the probability increased from July 28, 2020 to December 31, 2020 as a result of SSc-002 phase 3
and CF-002 phase 2 trial results. The additional significant assumption used when valuing the default feature is the probability of defaulting on the repayment of loan. The
Company has determined the probability increased from July 28, 2020 to December 30, 2020. As the probability of both features increased the fair value of the derivative
liability has increased at December 31, 2020. The value of these features was determined to be approximately $546,000 at July 28, 2020 and $797,000 at December 31,
2020 which resulted in $251,000 of other expense. The Company considers the fair value of the derivative liability to be Level 3 under the three-tier fair value hierarchy.

A roll forward of the fair value of the derivative liability for the year ended December 31, 2020 is presented below.
