Note Regarding Forward-Looking Statements

This  Annual  Report  on  Form  10-K  and  the  information  incorporated  herein  by  reference  contain  forward-looking  statements  that  involve  a
number of risks and uncertainties, many of which are beyond our control. Although our forward-looking statements reflect the good faith judgment of our
management, these statements can only be based on facts and factors currently known by us. Consequently, these forward-looking statements are inherently
subject  to  risks  and  uncertainties,  and  actual  results  and  outcomes  may  differ  materially  from  results  and  outcomes  discussed  in  the  forward-looking
statements as a result of various factors, including those set forth below under the caption “Risk Factors.”

Forward-looking  statements  in  this  Annual  Report  and  in  our  other  reports  with  the  Securities  and  Exchange  Commission  (the  “SEC”),  for

example, may include statements regarding:

● our ability to submit our product candidates through the 505(b)(2) regulatory pathway for approval by the U.S. Food and Drug Administration (the

“FDA”);

● our ability to obtain FDA approval for our product candidates;

● our ability to comply with all U.S. and foreign regulations concerning the development, manufacture and sale of our product candidates;

● our ability to maintain, protect and enhance our intellectual property;

● costs associated with initiating and defending intellectual property infringement and other claims;

● our expectations regarding the period during which we qualify as an emerging growth company under the JOBS Act;

● future acquisitions of or investments in complementary companies or technologies; and

Overview

PART I

Eton  is  an  innovative  pharmaceutical  company  focused  on  developing,  acquiring,  and  commercializing  innovative  products  to  address  unmet

needs in patients suffering from rare diseases.

The  Company  currently  has  three  commercial  rare  disease  products,  ALKINDI  SPRINKLE®  for  the  treatment  of  adrenocortical  insufficiency,
Carglumic Acid for the treatment of hyperammonemia due to N-acetylglutamate synthase (NAGS) deficiency, and Betaine Anhydrous for the treatment of
homocystinuria and has three additional product candidates in late-stage development. The Company is developing dehydrated alcohol injection, which has
received Orphan Drug Designation for the treatment of methanol poisoning, ZENEO® hydrocortisone autoinjector for the treatment of adrenal crisis, and
ET-400.

ALKINDI SPRINKLE® (hydrocortisone granules) - This product was approved by the FDA in September 2020 as a replacement therapy for
Adrenocortical Insufficiency (“AI”) in children under 17 years of age. The product is the first and only FDA-approved granule hydrocortisone
formulation for the treatment of AI designed for use in children. We acquired U.S. marketing rights to the product in March 2020 and launched
ALKINDI  SPRINKLE®  in  December  2020  with  a  sales  force  targeting  pediatric  endocrinologists.  We  believe  there  are  approximately  10,000
children  currently  suffering  from  AI  in  the  United  States.  ALKINDI  SPRINKLE®  is  protected  by  three  issued  patents  that  extend  to  2034.  In
January 2021, we announced the acquisition of Canadian rights to ALKINDI SPRINKLE®.

Carglumic Acid  tablets  -  Our  Carglumic  Acid  product  is  an  FDA-approved  generic  version  of  Carbaglu®.  Our  product  is  approved  for  the
treatment  of  acute  and  chronic  hyperammonemia  due  to  N-acetylglutamate  Synthase  (NAGS)  deficiency.  We  acquired  marketing  rights  to  the
product in October 2021 and launched the product in December 2021. We promote the product with our internal sales force.

Betaine Anhydrous for Oral Solution - Our Betaine Anhydrous product is an FDA-approved generic version of Cystadane® for the treatment of
homocystinuria,  a  rare  inherited  condition  that  is  estimated  to  impact  less  than  2,000  patients  in  the  United  States.  We  acquired  the  product  in
September 2022 and expect to relaunch in early 2023.

Dehydrated Alcohol Injection - Our dehydrated alcohol injection product candidate is currently under review with the FDA for the treatment of
methanol poisoning. The application has been assigned a Target Action Date of June 27, 2023. The product was granted Orphan Drug Designation
in 2020. We believe the dehydrated alcohol injection market is more than $70 million annually.

ET-400 -  Eton  expects  to  submit  a  new  drug  application  for  the  adrenal  insufficiency  product  by  the  end  of  2023,  which  could  allow  for  an
approval and launch of the product in 2024.

ZENEO® Hydrocortisone Autoinjector - Our ZENEO® hydrocortisone autoinjector product candidate is a proprietary needle-free autoinjector
under development for the treatment of adrenal crisis. We acquired U.S. marketing rights to the product candidate from Crossject in June 2021.
Currently  patients  suffering  from  adrenal  crisis  typically  use  Solu-Cortef,  a  lyophilized  hydrocortisone  injection  kit  that  must  be  reconstituted
prior  to  delivery.  The  current  market  for  Solu-Cortef  is  more  than  $85  million  annually  based  on  IQVIA  data.  We  believe  our  needle-free
autoinjector will be preferred by patients. We expect to submit a New Drug Application (“NDA”) for the product in 2024, which could allow for
FDA approval in 2025.

In  addition,  the  Company  is  entitled  to  royalties  or  milestone  payments  from  five  FDA-approved  products  and  one  product  candidate  under
development  that  the  Company  developed  and  out-licensed.  The  products  are  Alaway®  Preservative  Free,  EPRONTIA®,  Cysteine  Hydrochloride,
ZONISADE™, Biorphen®, and Lamotrigine for Oral Suspension.

Alaway®  Preservative  Free (ketotifen fumarate) - Alaway  Preservative  Free  is  the  first  and  only  preservative-free  ophthalmic  product  FDA-
approved for the treatment of allergic conjunctivitis. The Company sold the product rights to Bausch Health in February 2019. Bausch Health is
responsible for commercialization of the product which was launched in February 2021 and we receive a twelve percent royalty on the product’s
net sales.

EPRONTIA® (topiramate  oral  solution)  -  EPRONTIA®  is  the  only  FDA-approved  liquid  formulation  of  topiramate.  It  is  approved  for  three
indications, including: monotherapy for treatment of partial-onset or primary general tonic-clonic seizures in patients two years of age and older;
adjunctive therapy for treatment of partial-onset seizures, including seizures associated with Lennox-Gastaut syndrome in patients two years of
age and older; and as a preventive treatment of migraine in patients 12 years of age and older. The product was approved in November 2021 and
launched by Azurity Pharmaceuticals, Inc. (“Azurity”) in December 2021.

Cysteine Hydrochloride - Cysteine hydrochloride is an FDA-approved generic form of EXELA Pharma Sciences’ Elcys® product indicated for
use  as  an  additive  to  amino  acid  solutions  to  meet  the  nutritional  requirements  of  newborn  infants.  The  product  is  now  owned  by  Dr.  Reddy’s
Laboratories S.A. (“Dr. Reddy’s”).

ZONISADE™ (zonisamide oral suspension) - The product is an FDA-approved innovative liquid formulation of zonisamide for the treatment of
partial seizures in patients with epilepsy. The product was approved in July 2022.

Biorphen® -  Biorphen  is  the  first  and  only  FDA-approved  formulation  of  ready-to-use  phenylephrine  injection.  Biorphen  is  indicated  for  the
treatment  of  clinically  important  hypotension  resulting  primarily  from  vasodilation  in  the  setting  of  anesthesia.  The  product  was  approved  in
October 2019 and launched in December 2019. The product is marketed by Dr. Reddy’s.

Lamotrigine  for  Oral  Suspension  -  The  product  is  an  innovative  liquid  formulation  of  lamotrigine  under  development  for  the  treatment  of
epilepsy. The product’s NDA was previously submitted to the FDA and received a Complete Response Letter (“CRL”) in May 2022. Azurity is
working on addressing the items identified in the CRL in order to resubmit the product’s NDA.

Goals and Strengths

Our goal is to become a leading profitable pharmaceutical company that brings innovative treatments to rare disease patients. We believe we are
unique in the pharmaceutical industry in our ability to identify, acquire, and advance products through the development and regulatory process. Our biggest
competitive strengths are:

● Business  development  experience  –  our  ability  to  identify  and  execute  transactions  on  under-appreciated  development  assets.  Our  team  has
completed  over  150  business  development  transactions  throughout  their  careers  and  their  industry  connections  and  track  record  provide  the
company with proprietary deal flow. We typically avoid participating in broker led transactions of auction processes.

● Regulatory expertise  –  our  knowledge  and  experience  gaining  FDA  approval,  and  particularly  our  knowledge  within  the  505(b)(2)  regulatory
pathway, provides drug sponsors with the opportunity to leverage existing data or literature to drastically expedite drug development timelines and
reduce investment.

Sales and Marketing

We  currently  commercialize  three  orphan  products  under  our  own  label  with  our  internal  infrastructure  and  sales  force.  We  currently
commercialize  ALKINDI  SPRINKLE®,  Carglumic  Acid,  and  Betaine  Anhydrous  in  the  United  States.  These  products  are  distributed  to  patients  via
specialty pharmacies, which support customer service and reimbursement activities.

In our royalty product category, the products are commercialized by our partners. Bausch Health is responsible for all sale and marketing activities
related  to  Alaway  Preservative  Free,  and  Azurity  is  responsible  for  all  sales  and  marketing  activities  related  to  EPRONTIA®,  ZONISADE™,  and
lamotrigine suspension. In all cases we receive a royalty on net sales of the products.

Research and Development

We  currently  have  eight  employees  that  support  our  product  research  and  development  activities.  In  addition,  we  utilize  external  sources  for
various product development activities, including the resources of our product development partners for certain product candidates and through the use of
contract laboratory services on a fee for service model.

Manufacturing and Suppliers

We rely on third-party contract manufacturing organizations (“CMOs”) to manufacture our products. All of our finished product manufacturing
partners are based in the United States or Europe. We seek to work with CMOs that have a long history of quality and FDA compliance. All products are
manufactured in compliance with current Good Manufacturing Processes (“cGMP”), and our internal quality system requires us to enter quality agreements
with and audit all of our manufacturers prior to commercializing the product. Our choice to rely on external manufacturers significantly reduces the amount
of capital invested in our business and allows us the flexibility to pursue a broad range of opportunities beyond the specific capabilities of a single facility.

Intellectual Property

Our  policy  is  to  seek  to  protect  our  proprietary  position  by,  among  other  methods,  filing  U.S.  and  foreign  patent  applications  related  to  our
proprietary technology, inventions and improvements that are important to the development of our business. We also rely on our trade secrets, know-how
and continuing technological innovation to develop and maintain our proprietary position. We vigorously defend our intellectual property to preserve our
rights and gain the benefit of our technological investments. Our business is not dependent, however, upon any single patent, trademark or contract.

ALKINDI SPRINKLE® is protected by three issued patents that extend to 2034. We intend to seek patent protection on our internally developed

products as circumstances warrant.

Government Regulations and Funding

Pharmaceutical companies are subject to extensive regulation by foreign, federal, state and local agencies, such as the FDA, and various European
regulatory authorities. The manufacture, distribution, marketing and sale of pharmaceutical products are subject to government regulation in the United
States  and  various  foreign  countries.  Additionally,  in  the  United  States,  we  must  follow  rules  and  regulations  established  by  the  FDA  requiring  the
presentation of data indicating that our products are safe and efficacious and are manufactured in accordance with cGMP regulations. If we do not comply
with applicable requirements, we may be fined, the government may refuse to approve our marketing applications or allow us to manufacture or market our
products,  and  we  may  be  criminally  prosecuted.  We,  and  our  manufacturers  and  contract  research  organizations  (“CROs”),  may  also  be  subject  to
regulations  under  other  foreign,  federal,  state  and  local  laws,  including,  but  not  limited  to,  the  U.S.  Occupational  Safety  and  Health  Act,  the  Resource
Conservation and Recovery Act, the Clean Air Act and import, export and customs regulations as well as the laws and regulations of other countries. The
U.S. government has increased its enforcement activity regarding illegal marketing practices domestically and internationally. As a result, pharmaceutical
companies must ensure their compliance with the Foreign Corrupt Practices Act and federal healthcare fraud and abuse laws, including the False Claims
Act.

These regulatory requirements impact our operations and differ from one country to another, so that securing the applicable regulatory approvals
of one country does not imply the approval of another country. The approval procedures involve high costs and are manpower intensive, usually extend
over many years and require highly skilled and professional resources.

FDA Market Approval Process

The steps required to be taken before a new drug may be marketed in the United States generally include:

● completion of pre-clinical laboratory and animal testing;

● completion of required chemistry, manufacturing and controls testing;

● the submission to the FDA of an investigational new drug or IND, the application for which must be evaluated and found acceptable by the

FDA before human clinical trials may commence;

● performance of adequate and well-controlled human clinical trials to establish the safety, pharmacokinetics and efficacy of the proposed drug

for its intended use;

● submission and approval of an NDA; and

● agreement with FDA of the language on the package insert.

Clinical  studies  are  conducted  under  protocols  detailing,  among  other  things,  the  objectives  of  the  study,  what  types  of  patients  may  enter  the
study, schedules of tests and procedures, drugs, dosages, and length of study, as well as the parameters to be used in monitoring safety, and the efficacy
criteria  to  be  evaluated.  A  protocol  for  each  clinical  study  and  any  subsequent  protocol  amendments  must  be  submitted  to  the  FDA  as  part  of  the  IND
process.

Clinical trials are usually conducted in three phases. Phase 1 clinical trials are normally conducted in small groups of healthy volunteers to assess
safety of various dosing regimens and pharmacokinetics. After a safe dose has been established, in Phase 2 clinical trials the drug is administered to small
populations of sick patients to look for initial signs of efficacy in treating the targeted disease or condition and to continue to assess safety. Phase 3 clinical
trials are usually multi-center, double-blind controlled trials in larger numbers of subjects at various sites to assess as fully as possible both the safety and
effectiveness of the drug.

Clinical  trials  must  be  conducted  in  accordance  with  the  FDA’s  Good  Clinical  Practices  (“cGCP”)  requirements.  The  FDA  may  order  the
temporary or permanent discontinuation of a clinical study at any time or impose other sanctions if it believes that the clinical study is not being conducted
in  accordance  with  FDA  requirements  or  that  the  participants  are  being  exposed  to  an  unacceptable  health  risk.  An  institutional  review  board  (“IRB”)
generally must approve the clinical trial design and patient informed consent at study sites that the IRB oversees and may halt a study, either temporarily or
permanently, for failure to comply with the IRB’s requirements, or may impose other conditions. Additionally, some clinical studies are overseen by an
independent  group  of  qualified  experts  organized  by  the  clinical  study  sponsor,  known  as  a  data  safety  monitoring  board  or  committee.  This  group
recommends whether or not a trial may move forward at designated check-points based on access to certain data from the study. The clinical study sponsor
may also suspend or terminate a clinical trial based on evolving business objectives and/or competitive climate.

As a product candidate moves through the clinical testing phases, manufacturing processes are further defined, refined, controlled and validated.
The level of control and validation required by the FDA increases as clinical studies progress. We and the third-party manufacturers on which we rely for
the  manufacture  of  our  product  candidates  and  their  respective  components  (including  the  active  pharmaceutical  ingredient  (“API”))  are  subject  to
requirements  that  drugs  be  manufactured,  packaged  and  labeled  in  conformity  with  cGMP.  To  comply  with  cGMP  requirements,  manufacturers  must
continue to spend time, money and effort to meet requirements relating to personnel, facilities, equipment, production and process, labeling and packaging,
quality control, recordkeeping and other requirements.

After completion of all required testing in accordance with all applicable regulatory requirements, detailed information on the product candidate is
submitted to the FDA in the form of an NDA, requesting approval to market the product for one or more indications, together with payment of a user fee,
unless waived. An NDA includes all relevant data available from pertinent nonclinical and clinical studies, including negative or ambiguous results as well
as  positive  findings,  together  with  detailed  information  on  the  chemistry,  manufacture,  controls  and  proposed  labeling,  among  other  things.  To  support
marketing  approval,  the  data  submitted  must  be  sufficient  in  quality  and  quantity  to  establish  the  safety  and  efficacy  of  the  product  candidate  for  its
intended use to the satisfaction of the FDA.

If  an  NDA  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review  of  the  NDA.  Under  the  Prescription  Drug  User  Fee  Act
(“PDUFA”) the FDA’s goal is to complete its initial review and respond to the applicant within ten months of submission, unless the application relates to
an unmet medical need, or is for a serious or life-threatening indication, in which case the goal may be within six months of NDA submission. However,
the review process and the target response date under PDUFA may be extended if the FDA requests or the NDA sponsor otherwise provides additional
information or clarification regarding information already provided in the NDA. During its review of an NDA, the FDA may refer the application to an
advisory  committee  for  review,  evaluation  and  recommendation  as  to  whether  the  application  should  be  approved.  The  FDA  is  not  bound  by  the
recommendation of the advisory committee, but it typically follows such recommendations. Data from clinical studies are not always conclusive and the
FDA and/or any advisory committee it appoints may interpret data differently than the applicant.

After  the  FDA  evaluates  the  NDA  and  inspects  manufacturing  facilities  where  the  drug  product  and/or  its  API  will  be  produced,  it  will  either
approve commercial marketing of the drug product with prescribing information for specific indications or issue a CRL indicating that the application is
not ready for approval and stating the conditions that must be met in order to secure approval of the NDA. If the CRL requires additional data and the
applicant subsequently submits that data, the FDA nevertheless may ultimately decide that the NDA does not satisfy its criteria for approval. The FDA
could also approve the NDA with a Risk Evaluation and Mitigation Strategies (“REMS”) plan to mitigate risks, which could include medication guides,
physician communication plans, or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools.
The FDA also may condition approval on, among other things, changes to proposed labeling, development of adequate controls and specifications, or a
commitment  to  conduct  post-marketing  testing.  Such  post-marketing  testing  may  include  Phase  4  clinical  trials  and  surveillance  to  further  assess  and
monitor the product’s safety and efficacy after approval.

7

 
 
 
 
 
 
 
If the FDA approves one of our product candidates, we will be required to comply with a number of post-approval regulatory requirements. We would be
required to report, among other things, certain adverse reactions and production problems to the FDA, provide updated safety and efficacy information and
comply with requirements concerning advertising and promotional labeling for any of our products. Also, quality control and manufacturing procedures
must  continue  to  conform  to  cGMP  after  approval,  and  the  FDA  periodically  inspects  manufacturing  facilities  to  assess  compliance  with  cGMP,  which
imposes extensive procedural, substantive and record-keeping requirements. If we seek to make certain changes to an approved product, such as certain
manufacturing changes, we will need FDA review and approval before the change can be implemented. For example, if we change the manufacturer of a
product or our API, the FDA may require stability or other data from the new manufacturer. Such data will take time and are costly to generate, and the
delay associated with generating these data may cause interruptions in our ability to meet commercial demand, if any. While physicians may use products
for indications that have not been approved by the FDA, we may not label or promote the product for an indication that has not been approved. Securing
FDA approval for new indications is similar to the process for approval of the original indication and requires, among other things, submitting data from
adequate and well-controlled studies that demonstrate the product’s safety and efficacy in the new indication. Even if such studies are conducted, the FDA
may not approve any change in a timely fashion, or at all.

The FDA may also require post-marketing testing or Phase 4 testing, as well as risk minimization action plans and surveillance to monitor the

effects of an approved product or place conditions on an approval that could otherwise restrict the distribution or use of the product.

Section 505(b)(2) New Drug Applications

We intend to submit applications for certain product candidates via the 505(b)(2) regulatory pathway. As an alternate path for FDA approval of
new  indications  or  new  formulations  of  previously  approved  products,  a  company  may  submit  a  Section  505(b)(2)  NDA,  instead  of  a  “stand-alone”  or
“full” NDA. Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act (“FDCA”) was enacted as part of the Drug Price Competition and Patent Term
Restoration Act of 1984, otherwise known as the Hatch-Waxman Amendments. Section 505(b)(2) permits the submission of an NDA where at least some
of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of
reference. Some examples of products that may be allowed to follow a 505(b)(2) path to approval are drugs that have a new dosage form, strength, route of
administration, formulation or indication.

The Hatch-Waxman Amendments permit the applicant to rely upon certain published nonclinical or clinical studies conducted for an approved
product or the FDA’s conclusions from prior review of such studies. The FDA may require companies to perform additional studies or measurements to
support  any  changes  from  the  approved  product.  The  FDA  may  then  approve  the  new  product  for  all  or  some  of  the  labeled  indications  for  which  the
reference product has been approved, as well as for any new indication supported by the Section 505(b)(2) application. While references to nonclinical and
clinical data not generated by the applicant or for which the applicant does not have a right of reference are allowed, all development, process, stability,
qualification and validation data related to the manufacturing and quality of the new product must be included in an NDA submitted under Section 505(b)
(2).

To  the  extent  that  the  Section  505(b)(2)  applicant  is  relying  on  the  FDA’s  conclusions  regarding  studies  conducted  for  an  already  approved
product,  the  applicant  must  provide  the  patent  number  and  certify  to  the  FDA  in  its  opinion  and  to  the  best  of  its  knowledge,  one  of  the  following
circumstances: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the listed patent has not expired, but will expire
on a particular date and approval is sought after patent expiration; or (iv) the listed patent is invalid or will not be infringed by the new product. The Section
505(b)(2) application also will not be approved until any non-patent exclusivity, such as exclusivity for obtaining approval of a new chemical entity, listed
in the Orange Book for the reference product has expired. If the Orange Book certifications outlined above are not accomplished, the Section 505(b)(2)
applicant may invest a significant amount of time and expense in the development of its products only to be subject to significant delay and patent litigation
before its products may be commercialized.

Section 505(j) Abbreviated New Drug Applications

The 505(j) pathway is used for product candidates that are therapeutically equivalent to an approved product. The underlying premise of the 505(j)
pathway is that a product candidate classified as therapeutically equivalent can be substituted for the approved product with the full expectation that the
substituted  product  will  produce  the  same  clinical  effect  and  safety  profile  as  the  approved  product  when  administered  under  the  same  conditions.  A
product  candidate  utilizing  the  505(j)  pathway  requires  an  abbreviated  new  drug  application,  (“ANDA”),  which  relies  on  the  FDA’s  finding  that  the
previously approved drug candidate is safe and effective. An ANDA generally must contain information to show that the product candidate is the same as
the  approved  product  with  respect  to  API,  conditions  of  use,  route  of  administration,  dosage  form,  strength  and  labeling,  with  certain  permissible
differences, and is the bioequivalent of the approved drug. The 505(j) pathway typically requires no clinical testing other than a bioequivalence trial. While
the  505(j)  pathway  is  typically  shorter  and  less  expensive  than  the  505(b)(2)  pathway,  the  505(b)(2)  pathway  allows  greater  flexibility  as  to  the
characteristics of the product candidate.

Other U.S. Healthcare Laws and Compliance Requirements

For  products  distributed  in  the  United  States,  we  will  also  be  subject  to  additional  healthcare  regulation  and  enforcement  by  the  federal

government and the states in which we conduct our business. Applicable federal and state healthcare laws and regulations include the following:

● The  U.S.  Anti-Kickback  Statute  prohibits,  among  other  things,  persons  from  knowingly  and  willfully  soliciting,  offering,  receiving,  or
providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase,
order,  lease,  or  recommendation  of,  any  good  or  service,  for  which  payment  may  be  made  under  federal  healthcare  programs  such  as
Medicare and Medicaid;

● The  federal  civil  and  criminal  false  claims  laws,  including  the  U.S.  False  Claims  Act,  can  be  enforced  by  individuals,  on  behalf  of  the
government,  through  civil  whistleblower  or  qui  tam  actions,  and  the  civil  monetary  penalties  law,  prohibits  individuals  or  entities  from,
among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government  claims  for  payment  that  are  false  or
fraudulent or making a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government;

● The  Health  Insurance  Portability  and  Accountability  Act  of  1996  (“HIPAA”),  which  prohibits,  among  other  things,  executing  a  scheme  to
defraud any healthcare benefit program, including private third-party payors, and knowingly and willfully falsifying, concealing or covering
up  a  material  fact  or  making  any  materially  false,  fictitious,  or  fraudulent  statement  in  connection  with  the  delivery  of  or  payment  for
healthcare benefits, items, or services;

● HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  and  their  implementing  regulations,
imposes  obligations,  including  mandatory  contractual  terms,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of
individually identifiable health information; and

9

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● Analogous state laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing arrangements and
claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers, state laws that
require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance
guidance  promulgated  by  the  federal  government;  state  and  local  laws  that  require  drug  manufacturers  to  report  information  related  to
payments  and  other  transfers  of  value  to  physicians  and  other  healthcare  providers  or  marketing  expenditures;  state  laws  that  require  the
reporting  of  information  related  to  drug  pricing;  state  and  local  laws  requiring  the  registration  of  pharmaceutical  sales  and  medical
representatives;  and  state  and  foreign  laws,  such  as  the  General  Data  Protection  Regulation  (EU)  2016/679,  governing  the  privacy  and
security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted
by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory safe harbors, it is possible that some of
our business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the federal or
state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including significant criminal, civil, and
administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, integrity oversight
and reporting obligations to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations.

Reimbursement

Sales of our products in the United States may depend, in part, on the extent to which the costs of the products will be covered and reimbursed by
third-party  payors,  such  as  government  health  programs,  commercial  insurance  and  managed  health  care  organizations.  These  third-party  payors  are
increasingly challenging the prices charged for medical products and services. Additionally, the containment of health care costs has become a priority of
federal  and  state  governments,  and  the  prices  of  drugs  have  been  a  focus  in  this  effort.  The  United  States  government,  state  legislatures  and  foreign
governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,  restrictions  on  reimbursement  and
requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in
jurisdictions with existing controls and measures, could further limit our net revenue and results. If these third-party payors do not consider our products to
be cost-effective compared to other available therapies, they may not cover our products after approval as a benefit under their plans or, if they do, the level
of payment may not be sufficient to allow us to sell our products on a profitable basis.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, (the “MMA”), imposed new requirements for the distribution and
pricing of prescription drugs for Medicare beneficiaries and included a major expansion of the prescription drug benefit under Medicare Part D. Under Part
D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities which will provide coverage of outpatient prescription drugs.
Part D plans include both stand-alone prescription drug benefit plans and prescription drug coverage as a supplement to Medicare Advantage plans. Unlike
Medicare Parts A and B, Part D coverage is not standardized. Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs,
and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug
formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or
class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government
payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However, any negotiated
prices for our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the
MMA applies only to drug benefits for Medicare beneficiaries, private third-party payors often follow Medicare coverage policy and payment limitations in
setting  their  own  payment  rates.  Any  reduction  in  payment  that  results  from  the  MMA  may  result  in  a  similar  reduction  in  payments  from  non-
governmental payors.

10

 
 
 
 
 
 
 
 
Decreases in third-party reimbursement for our products or a decision by a third-party payor to not cover our products could reduce physician

usage of the products and have a material adverse effect on our sales, results of operations and financial condition.

Healthcare Reform

In  the  United  States  and  some  foreign  jurisdictions,  there  have  been  a  number  of  legislative  and  regulatory  changes  and  proposed  changes
regarding the health-care system that could prevent or delay marketing approval pharmaceutical products, restrict or regulate post-approval activities and
affect our ability to profitably sell our product candidates. Legislative and regulatory proposals have been made to expand post-approval requirements and
restrict sales and promotional activities for pharmaceutical products.

For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act,
(collectively, the “Health Care Reform Law”) was enacted, which substantially changes the way health care is financed by both governmental and private
insurers, and significantly impacts the U.S. pharmaceutical industry. The Health Care Reform Law, among other things, imposed reporting requirements on
manufacturers related to drug samples and financial relationships with physicians and teaching hospitals, increased the minimum Medicaid rebates owed by
manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations,
established annual fees on manufacturers of certain branded prescription drugs, and established a Medicare Part D coverage gap discount program.

Some of the provisions of the Health Care Reform Law have yet to be implemented, and there have been judicial and Congressional challenges to
certain aspects of the Health Care Reform Law. In addition, Congress has considered legislation that would repeal or repeal and replace all or part of the
Health Care Reform Law. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under
the Health Care Reform Law have been signed into law. The Tax Cuts and Jobs Act of 2017 (the “Tax Act”) included a provision which repealed, effective
January  1,  2019,  the  tax-based  shared  responsibility  payment  imposed  by  the  Health  Care  Reform  Law  on  certain  individuals  who  fail  to  maintain
qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” The Bipartisan Budget Act of 2018, among
other things, amended the Health Care Reform Law, effective January 1, 2019, to increase from 50 percent to 70 percent the point-of-sale discount that is
owed by pharmaceutical manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred
to as the “donut hole”. In 2018, a Texas U.S. District Court Judge ruled that the Health Care Reform Law is unconstitutional in its entirety because the
“individual mandate” was repealed by Congress as part of the Tax Act. On June 17, 2021, the U.S. Supreme Court overturned the 2018 Texas U.S. District
Court decision. It is unclear how subsequent appeals and other efforts to repeal and replace the Health Care Reform will impact our business.

In  addition,  other  legislative  changes  have  been  proposed  and  adopted  in  the  United  States  since  the  Health  Care  Reform  Law  was  enacted,

including:

●   In  August  2011,  President  Obama  signed  into  law  the  Budget  Control  Act  of  2011,  which,  among  other  things,  created  the  Joint  Select
Committee on Deficit Reduction to recommend to Congress proposals for deficit reduction of at least $1.2 trillion for the years 2013 through 2021.
The Joint Select Committee on Deficit Reduction did not achieve a targeted deficit reduction, which triggered the legislation’s automatic reduction to
several  government  programs.  This  includes  aggregate  reductions  to  Medicare  payments  to  providers  of,  up  to  2%  per  fiscal  year,  and,  due  to
subsequent legislative amendments, will remain in effect through 2030 unless Congress takes additional action. These reductions went into effect in
April  2013  and,  due  to  subsequent  legislative  amendments  to  the  statute,  will  remain  in  effect  through  2030  unless  additional  action  is  taken  by
Congress.

● On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and small
group marketplaces, which may have the effect of relaxing the essential health benefits required under the Health Care Reform Law for plans sold
through such marketplaces.

● On May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to
access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval.
Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the
FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a
result of the Right to Try Act.

● On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning

January 1, 2020.

Further,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of  pharmaceutical  pricing  practices  in  light  of  the  rising  cost  of
prescription  drugs  and  biologics.  Such  scrutiny  has  resulted  in  several  recent  U.S.  Congressional  Inquiries  and  proposed  and  enacted  federal  and  state
legislation designed to, among other things, bring more transparency to product pricing, reduce the cost of prescription drugs under Medicare, review the
relationship  between  pricing  and  manufacturer  and  patient  programs,  and  reform  government  program  reimbursement  methodologies  for  products.  At  a
federal level, President Biden signed an Executive Order on July 9, 2021, affirming the administration’s policy to (i) support legislative reforms that would
lower the prices of prescription drug and biologics, including by allowing Medicare to negotiate drug prices, by imposing inflation caps, and, by supporting
the development and market entry of lower-cost generic drugs and biosimilars; and (ii) support the enactment of a public health insurance option. Among
other  things,  the  Executive  Order  also  directs  the  U.S.  Department  of  Health  &  Human  Services  (“HHS”)  to  provide  a  report  on  actions  to  combat
excessive pricing of prescription drugs, enhance the domestic drug supply chain, reduce the price that the Federal government pays for drugs, and address
price  gouging  in  the  industry;  and  directs  the  FDA  to  work  with  states  and  Indian  Tribes  that  propose  to  develop  section  804  Importation  Programs  in
accordance with the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, and the FDA’s implementing regulations. FDA released
such implementing regulations on September 24, 2020, which went into effect on November 30, 2020, providing guidance for states to build and submit
importation  plans  for  drugs  from  Canada.  On  September  25,  2020,  CMS  stated  drugs  imported  by  states  under  this  rule  will  not  be  eligible  for  federal
rebates  under  Section  1927  of  the  Social  Security  Act  and  manufacturers  would  not  report  these  drugs  for  “best  price”  or  Average  Manufacturer  Price
purposes. Since these drugs are not considered covered outpatient drugs, CMS further stated it will not publish a National Average Drug Acquisition Cost
for  these  drugs.  If  implemented,  importation  of  drugs  from  Canada  may  materially  and  adversely  affect  the  price  we  receive  for  any  of  our  product
candidates. Additionally, on November 30, 2020, HHS published a regulation removing safe harbor protection for price reductions from pharmaceutical
manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule
also  creates  a  new  safe  harbor  for  price  reductions  reflected  at  the  point-of-sale,  as  well  as  a  safe  harbor  for  certain  fixed  fee  arrangements  between
pharmacy  benefit  managers  and  manufacturers.  Pursuant  to  court  order,  the  removal  and  addition  of  the  aforementioned  safe  harbors  were  delayed  and
recent legislation imposed a moratorium on implementation of the rule until January 1, 2032. Although a number of these and other proposed measures
may  require  authorization  through  additional  legislation  to  become  effective,  and  the  Biden  administration  may  reverse  or  otherwise  change  these
measures, both the Biden administration and Congress have indicated that they will continue to seek new legislative measures to control drug costs.

Most recently, on August 16, 2022, President Biden signed the Inflation Reduction Act (“IRA”) which provides for (i) the government to set or
negotiate prices for select high-cost Medicare Part D (beginning in 2026) and Medicare Part B drugs (beginning in 2028) that are more than nine years (for
small-molecule drugs) or 13 years (for biological products) from their FDA approval, (ii) manufacturers to pay a rebate for Medicare Part B and Part D
drugs  when  prices  increase  faster  than  inflation  beginning  in  2022  for  Medicare  Part  D  and  2023  for  Medicare  Part  B  drugs,  and  (iii)  Medicare  Part  D
redesign  which  replaces  the  current  coverage  gap  provisions  and  establishes  a  $2,000  cap  for  out-of-pocket  limits  costs  for  Medicare  beneficiaries
beginning in 2025, with manufacturers being responsible for 10% of costs up to the $2,000 cap and 20% after that cap is reached. Implementation of the
IRA is expected to be carried out through upcoming actions by regulatory authorities, the outcome of which is uncertain.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological
product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and
transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

We expect that the healthcare reform measures that have been adopted and may be adopted in the future, may result in more rigorous coverage
criteria  and  in  additional  downward  pressure  on  the  price  that  we  receive  for  any  approved  product  and  could  seriously  harm  our  future  revenues.  Any
reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private third-party payors.

In June 2016, the electorate in the UK voted in favor of leaving the EU (commonly referred to as “Brexit”), and the UK formally left the EU on
January 31, 2020. There was a transition period during which EU pharmaceutical laws continued to apply to the UK, which expired on December 31, 2020.
However, the EU and the UK have concluded a trade and cooperation agreement, or TCA, which was provisionally applicable since January 1, 2021, and
has been formally applicable since May 1, 2021. The TCA includes specific provisions concerning pharmaceuticals, which include the mutual recognition
of GMP, inspections of manufacturing facilities for medicinal products and GMP documents issued but does not foresee wholesale mutual recognition of
UK  and  EU  pharmaceutical  regulations.  At  present,  Great  Britain  has  implemented  EU  legislation  on  the  marketing,  promotion,  and  sale  of  medicinal
products through the Human Medicines Regulations 2012 (as amended) (under the Northern Ireland Protocol, the EU regulatory framework will continue
to apply in Northern Ireland). The regulatory regime in Great Britain therefore largely aligns with current EU regulations, however it is possible that these
regimes will diverge in future now that Great Britain’s regulatory system is independent from the EU and the TCA does not provide for mutual recognition
of UK and EU pharmaceutical legislation.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal, and state levels directed at broadening
the  availability  of  healthcare  and  containing  or  lowering  the  cost  of  healthcare.  The  implementation  of  cost  containment  measures  or  other  healthcare
reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product. Such reforms could have an adverse effect
on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our
overall financial condition and ability to develop product candidates.

Risk Factor Summary

You should carefully consider the risks set forth in the section of this Annual Report of Form 10-K entitled “Risk Factors” beginning on page 16

of this Annual Report, including, but not limited to, the following:

● We are a specialty pharmaceutical company with a limited operating history, and it is difficult for potential investors to evaluate our business.
● We may have significant research, regulatory and development expenses as we advance our product candidates.
● We may need to grow the size of our organization, and we may experience difficulties in managing this growth.
● If product  liability  lawsuits  are  brought  against  us,  we  may  incur  substantial  liabilities  and  may  be  required  to  limit  commercialization  of  our

product candidates.

● We may acquire businesses or products, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.
● We  rely  significantly  on  information  technology  and  any  failure,  inadequacy,  interruption  or  security  lapse  of  that  technology,  including  any

cybersecurity incidents, could harm our ability to operate our business effectively.

● Sales of counterfeits of any of our product candidates, as well as unauthorized sales of any of our product candidates, may have adverse effects on

our revenues, business and results of operations and damage our brand and reputation.

● We  have  entered  into  several  arrangements  with  related  parties  for  the  development  and  marketing  of  certain  product  candidates  and  these

arrangements present potential conflicts of interest.

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

effectively.

● Our competitors may obtain FDA or other regulatory approval for comparable products more rapidly than we may obtain approval for ours, and
the risk of our competitors doing so may lead us to develop drug candidates without disclosing certain information with regard to such candidates.
● If we  are  not  able  to  obtain  any  required  regulatory  approvals  for  our  product  candidates,  we  will  not  be  able  to  commercialize  our  product

candidate and our ability to generate revenue will be limited.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● If  the  FDA  does  not  conclude  that  our  product  candidates  satisfy  the  requirements  for  the  505(b)(2)  regulatory  approval  pathway,  or  if  the
requirements for approval of any of our product candidates under Section 505(b)(2) are not as we expect, the approval pathway for our product
candidates  will  likely  take  significantly  longer,  cost  significantly  more  and  encounter  significantly  greater  complications  and  risks  than
anticipated, and in any case may not be successful.

● An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or

prevent the review or approval of our product candidate.

● Even if we receive regulatory approval for any of our product candidates, we may not be able to successfully commercialize the product, and the

revenue that we generate from its sales, if any, may be limited.

● We are  subject  to  ongoing  obligations  and  continued  regulatory  review,  which  may  result  in  significant  additional  expense.  Additionally,  our
product 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 product candidates.

● Significant additional labeling or warning requirements or limitations on the availability of our products may inhibit sales of affected products.
● Current  and  future  legislation  may  increase  the  difficulty  and  cost  for  us  to  obtain  marketing  approval  of  and  commercialize  our  product

candidates and affect the prices we may obtain.

● Our future  growth  may  depend,  in  part,  on  our  ability  to  penetrate  international  markets,  where  we  would  be  subject  to  additional  regulatory

burdens and other risks and uncertainties.

● If we market any of our products or product candidates in a manner that violates health care fraud and abuse laws, or if we violate government

price reporting laws, we may be subject to civil or criminal penalties.

● We may not be able to establish agreements with third parties with whom we wish to collaborate and, if we are able to establish them, we may not
be able to establish them on commercially reasonable terms, which could result in alterations or delays of our development and commercialization
plans.

● We expect  to  rely  on  third  parties  to  conduct  clinical  trials  for  our  product  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  any  of  our  product
candidates and our business would be substantially harmed.

● We enter  into  various  contracts  in  the  normal  course  of  our  business,  some  or  all  of  which  may  require  us  to  indemnify  the  other  party  to  the
contract.  In  the  event  we  have  to  perform  under  these  indemnification  provisions,  it  could  have  an  adverse  effect  on  our  business,  financial
condition and results of operations.

● Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product 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.

● 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.

● Third-party coverage and reimbursement and health care cost containment initiatives and treatment guidelines may constrain our future revenues.
● We are subject to extensive laws and regulations related to data privacy, and our failure to comply with these laws and regulations could harm our

business.

● We  will  depend  on  rights  to  certain  pharmaceutical  compounds  that  have  been  acquired  by  us.  We  do  not  have  complete  control  over  these

pharmaceutical compounds and any loss of our rights to them could prevent us from selling our products.

● It is difficult and costly to protect our intellectual property rights, and we cannot ensure the protection of these rights.
● Changes in either U.S. or foreign patent law or interpretation of such laws could diminish the value of patents in general, thereby impairing our

ability to protect our products.

● Our  product  candidates  may  infringe  the  intellectual  property  rights  of  others,  which  could  increase  our  costs  and  delay  or  prevent  our

development and commercialization efforts.

● Others  may  claim  an  ownership  interest  in  our  intellectual  property,  which  could  expose  us  to  litigation  and  have  an  adverse  effect  on  our

prospects.

● 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.

Item 1A. Risk Factors

We operate in a dynamic and rapidly changing environment that involves numerous risks and uncertainties. Certain factors may have a material adverse
effect on our business, financial condition and results of operations, and you should carefully consider them. Accordingly, in evaluating our business, we
encourage you to consider the following discussion of risk factors, in its entirety, in addition to other information contained in this Annual Report on Form
10-K and our other public filings with the SEC. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our
results of operations and financial condition.

Risks Relating to Our Business

We are a specialty pharmaceutical company with a limited operating history, and it is difficult for potential investors to evaluate our business.

We  are  a  specialty  pharmaceutical  company  founded  in  April  2017  and  have  commenced  revenue-producing  operations  and  our  historical
operations  have  primarily  consisted  of  the  preliminary  formulation,  testing  and  development  of  our  various  product  candidates.  Our  limited  operating
history makes it difficult for potential investors to evaluate our initial product candidates or our prospective operations. As an early-stage company, we are
subject to all the risks inherent in the initial organization, financing, expenditures, complications and delays in a new business. Further, biopharmaceutical
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  product
development and commercialization, especially clinical-stage biopharmaceutical companies such as ours. As a company with a limited operating history,
we may be unable to:

● successfully implement or execute our current business plan or develop a business plan that is sound;

● successfully complete clinical trials and obtain regulatory approval for the marketing of our additional product candidates;

● successfully contract for the manufacture of our clinical drug products and establish a commercial drug supply;

● secure market exclusivity or adequate intellectual property protection for our product candidates;

● attract and retain an experienced management and advisory team; or

● raise sufficient funds in the capital markets to effectuate our business plan, including clinical development, regulatory approval and ongoing

commercialization for our product candidates.

There can be no assurance that our efforts will be successful or that we will ultimately be able to attain profitability. If we cannot successfully

execute any one of the foregoing, our business may not succeed.

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

As  our  development  and  commercialization  plans  and  strategies  develop,  we  may  need  to  expand  the  size  of  our  employee  and
consultant/contractor  base.  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 product candidates and any other future product candidates and our ability to compete effectively will depend, in part, on our
ability to effectively manage our future growth.

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

We face a potential risk of product liability as a result of the commercialization of our approved products and clinical testing of our new product
candidates and will face an even greater risk if we commercialize our current product candidates or any other future product. For example, we may be sued
if our approved products or any product we develop, including any of our product candidates, 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. In the United States, 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 product 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 current products or any of our product candidates or any future products that we may develop;

● 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 some or all of our product candidates; and

● a decline in the value of our stock.

We  carry  product  liability  insurance  we  consider  adequate  for  our  current  level  of  expected  product  sales,  clinical  testing  and  product
development.  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 our approved products or additional products we develop. Although we will endeavor to obtain
and maintain such insurance in coverage amounts which we deem adequate, 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 or products, or form strategic alliances, in the future, and we may not realize the benefits of such acquisitions.

We  may  acquire  additional  businesses  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 products resulting from a strategic alliance or acquisition that delay or prevent
us  from  realizing  their  expected  benefits  or  enhancing  our  business.  We  cannot  assure  you  that,  following  any  such  acquisition,  we  will  achieve  the
expected synergies to justify the transaction.

We  rely  significantly  on  information  technology  and  any  failure,  inadequacy,  interruption  or  security  lapse  of  that  technology,  including  any
cybersecurity incidents, could harm our ability to operate our business effectively.

Despite the implementation of security measures, our internal computer systems and those of third parties with which we contract are vulnerable
to  damage  from  cyber  attacks,  computer  viruses,  unauthorized  access,  natural  disasters,  terrorism,  war  and  telecommunication  and  electrical  failures.
System  failures,  accidents  or  security  breaches  could  cause  interruptions  in  our  operations,  and  could  result  in  a  material  disruption  of  our  product
development and clinical activities and business operations, in addition to possibly requiring substantial expenditures of resources to remedy. Cybersecurity
attacks in particular are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic
security breaches that could lead to disruptions in systems, misappropriation of our confidential or otherwise protected information and corruption of data.
The loss, theft or sabotage of product development or clinical trial data could result in delays in our regulatory approval efforts and significantly increase
our  costs  to  recover  or  reproduce  the  data.  To  the  extent  that  any  disruption  or  security  breach  were  to  result  in  a  loss  of,  or  damage  to,  our  data  or
applications,  or  inappropriate  disclosure  of  confidential  or  proprietary  information,  we  could  incur  liability  and  our  development  programs  and  the
development of our product candidates could be delayed.

Sales of counterfeits of any of our product candidates, as well as unauthorized sales of any of our product candidates, may have adverse effects on our
revenues, business and results of operations and damage our brand and reputation.

Our  current  approved  products  or  our  new  product  candidates  may  become  subject  to  competition  from  counterfeit  pharmaceutical  products,
which are pharmaceutical products sold under the same or very similar brand names and/or having a similar appearance to genuine products, but which are
sold without proper licenses or approvals. Such products divert sales from genuine products, often are of lower cost, often are of lower quality (having
different ingredients or formulations, for example), and have the potential to damage the reputation for quality and effectiveness of the genuine product.
Obtaining regulatory approval for our product candidates is a complex and lengthy process. If during the period while the regulatory approval is pending,
illegal sales of counterfeit products begin, consumers may buy such counterfeit products, which could have an adverse impact on our revenues, business
and results of operations. In addition, if illegal sales of counterfeits result in adverse side effects to consumers, we may be associated with any negative
publicity resulting from such incidents. Although pharmaceutical regulation, control and enforcement systems throughout the world have been increasingly
active  in  policing  counterfeit  pharmaceuticals,  we  may  not  be  able  to  prevent  third  parties  from  manufacturing,  selling  or  purporting  to  sell  counterfeit
products competing with our current products or our new product candidates. Such sales may also be occurring without our knowledge. The existence and
any  increase  in  production  or  sales  of  counterfeit  products  or  unauthorized  sales  could  negatively  impact  our  revenues,  brand  reputation,  business  and
results of operations.

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

We  depend  entirely  on  the  success  of  current  approved  products  and  our  new  product  candidates.  If  we  are  unable  to  generate  revenues  from  our
approved products and new product candidates, our ability to create stockholder value will be limited.

We have various product candidates under review with the FDA and are in the early stages of clinical development with a number of new product
candidates,  and  have  not  yet  generated  significant  revenues  from  our  approved  drug  products.  We  plan  on  submitting  our  clinical  trial  protocols  and
receiving approvals from the FDA and international regulatory authorities before we commence any clinical trials. We may not be successful in obtaining
acceptance from the FDA or comparable foreign regulatory authorities to start our clinical trials. If we do not obtain such acceptance, the time in which we
expect to commence clinical programs for any product candidate will be extended and such extension will increase our expenses and increase our need for
additional  capital.  Moreover,  there  is  no  guarantee  that  our  clinical  trials  will  be  successful  or  that  we  will  continue  clinical  development  in  support  of
additional product approvals from the FDA or comparable foreign regulatory authorities for any indication. We note that most product candidates never
reach the clinical development stage and even those that do commence clinical development have only a small chance of successfully completing clinical
development and gaining regulatory approval. Therefore, our business substantially depends entirely on the successful development, regulatory approval
and commercialization of our product candidates, which may never occur.

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
existing competitors and potential new competitors in a number of jurisdictions, many of which have or will 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  any  of  our  product  candidates  obsolete  or  uneconomical.  In  addition,  mergers  and  acquisitions  in  the
biotechnology and pharmaceutical industries may result in even more resources being concentrated among a smaller number of our competitors, potentially
reducing or eliminating our commercial opportunity. Furthermore, such potential competitors may enter the market before us, and their products may be
designed to circumvent our pending patent applications and any patents we may receive. They may also challenge, narrow or invalidate any granted patents
or our patent applications, and such patents and patent applications may fail to provide adequate protection for our product candidates. 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 product 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.

We face substantial competition, which may result in others discovering, developing and commercializing products before or more successfully than
our product candidates.

The  development  and  commercialization  of  new  drugs  is  highly  competitive.  We  face  competition  (from  major  pharmaceutical  companies,
specialty  pharmaceutical  companies  and  biotechnology  companies  worldwide)  with  respect  to  our  current  product  candidates  and  will  face  competition
with respect to any product candidates that we may seek to develop or commercialize in the future. We compete directly with companies that focus on
505(b)(2)  and  generic  drugs,  and  companies  dedicating  their  resources  to  novel  forms  of  therapies  for  these  indications.  Many  of  these  competitors  are
attempting to develop products for our target indications. We face the risk that our competitors will develop a competing product using the same 505(b)(2)
pathway that we intend to pursue. Our business model is to focus on product candidates that we consider to have a shorter timeline to, and lower cost of,
regulatory approval. These attributes can also be taken advantage of by our competitors to develop and obtain marketing approval of a competing product.
In addition, following FDA approval of our product candidates for which we have no patent protection, our competitors may seek to develop a competing
product pursuant to the 505(j) pathway, which is an abbreviated pathway used for the regulatory approval of generic product candidates. As a result of the
foregoing, we may find that the market opportunity for our product candidates for which we have no patent protection is relatively small due to the fact that
barriers to entry are low and generic competition may follow within relatively short time periods after our product is approved. With the proliferation of
new drugs and therapies in these areas, we expect to face increasingly intense competition as new technologies become available. Any product candidates
that we successfully develop and commercialize will compete with existing products and new products that may become available in the future.

18

 
 
 
 
 
 
 
 
There are products already approved for all of the indications we are targeting. Many of these approved products are well established therapies and
are widely accepted by physicians, patients and third-party payors. This may make it difficult for us to achieve our business strategy of replacing existing
products with our product candidates. In addition, where we are able to offer benefits over existing products offered by our competitors, those competitors
may reformulate their drugs in a manner that mimics the benefits offered by our product candidates. As noted below, many of our product candidates are
not eligible for patent protection or the market and data exclusivity provisions under the FDCA. Consequently, our commercial operations face significant
direct competition and our competitors may develop products that are similar to ours and perhaps safer, more effective, more convenient or less costly than
any that we are developing or that would render our product candidates obsolete or non-competitive. Our inability to successfully compete could negatively
impact our business, results of operations and stock price.

Our competitors may obtain FDA or other regulatory approval for comparable products more rapidly than we may obtain approval for ours, and the
risk of our competitors doing so may lead us to develop drug candidates without disclosing certain information with regard to such candidates.

The FDCA provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA, or supplement to an existing NDA or 505(b)(2) NDA if
new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to
the  approval  of  the  application,  (e.g.,  for  new  indications,  dosages,  strengths  or  dosage  forms  of  an  existing  drug).  Many  of  our  competitors  have
significantly  greater  financial,  manufacturing,  marketing,  drug  development,  technical  and  human  resources  than  we  do.  As  a  result,  many  of  our
competitors have the ability to bring a product candidate to market more rapidly than we can and depending on the nature of their product candidate they
could substantially delay the introduction of our product candidate into the market if their product qualifies for the market and data exclusivity provisions
under the FDCA. In order to preserve any competitive advantage, we will, at times, make the decision to pursue a product candidate for which we will not
disclose the API, dosage or reference drug until such time as we believe that any competitive advantage would not be materially compromised by public
disclosure of such information, which in some cases may be as late as our receipt of marketing approval from the FDA. Our business currently depends on
our  ability  to  bring  our  product  candidates  to  market  in  a  manner  that  preserves  our  perceived  competitive  advantage,  and  any  loss  of  that  competitive
advantage could negatively impact our business, results of operations and stock price.

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

We may be required to successfully complete clinical trials for our product candidates before we can apply for marketing approval. Even if we
complete any such clinical trials, it does not assure marketing approval. Any such clinical trials may be unsuccessful, which would materially harm our
business. Even if such initial clinical trials are successful, we may be required to conduct additional clinical trials to establish our product candidates’ safety
and efficacy before an NDA or foreign equivalents can be submitted to the FDA or comparable foreign regulatory authorities for marketing approval of our
product candidates.

Our success depends on the receipt of regulatory approval and the issuance of such regulatory approvals is uncertain and subject to a number of

risks, including the following:

● the results of any required toxicology studies may not support the submission of an IND for our product candidates;

● the  FDA  or  comparable  foreign  regulatory  authorities  or  Institutional  Review  Boards  (“IRB”),  may  disagree  with  the  design  or

implementation of our clinical trials;

● we may not be able to provide acceptable evidence of our product candidates’ safety and efficacy;

19

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● 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 or

other regulatory agencies for marketing approval;

● the dosing of our product candidates in any required clinical trial may not be at an optimal level;

● 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 or

other regulatory agencies for marketing approval;

● the dosing of our product candidates in any required 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 product 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; and

● the approval policies or regulations of the FDA may significantly change in a manner rendering our clinical data insufficient for approval.

Failure to obtain regulatory approval for our product candidates for the foregoing, or any other reasons, will prevent us from commercializing our
product  candidates,  and  our  ability  to  generate  sufficient  revenue  will  be  materially  impaired.  We  cannot  guarantee  that  regulators  will  agree  with  our
assessment of the results of the clinical trials we intend to conduct in the future or that such trials will be successful. The FDA 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 our product candidates.

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 the regulatory authorities. Changes in regulatory approval policies 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  our  product  candidates  will  prevent  us  from  commercializing  the  product
candidate, and our ability to generate sufficient revenue will be materially impaired.

If  the  FDA  does  not  conclude  that  our  product  candidates  satisfy  the  requirements  for  the  505(b)(2)  regulatory  approval  pathway,  or  if  the
requirements  for  approval  of  any  of  our  product  candidates  under  Section  505(b)(2)  are  not  as  we  expect,  the  approval  pathway  for  our  product
candidates will likely take significantly longer, cost significantly more and encounter significantly greater complications and risks than anticipated, and
in any case may not be successful.

We  intend  to  seek  FDA  approval  through  the  505(b)(2)  regulatory  pathway  for  the  majority  of  our  product  candidates.  The  Drug  Price
Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Act, added Section 505(b)(2) to the FDCA. Section 505(b)(2)
permits  the  filing  of  an  NDA  where  at  least  some  of  the  information  required  for  approval  comes  from  studies  that  were  not  conducted  by  or  for  the
applicant. If the FDA does not allow us to pursue the 505(b)(2) regulatory pathway for our product candidates as anticipated, we may need to conduct
additional clinical trials, provide additional data and information and meet additional standards for regulatory approval. If this were to occur, the time and
financial resources required to obtain FDA approval for our product candidates would likely substantially increase. Moreover, the inability to pursue the
505(b)(2)  regulatory  pathway  could  result  in  new  competitive  products  reaching  the  market  faster  than  our  product  candidates,  which  could  materially
adversely impact our competitive position and prospects. Even if we are allowed to pursue the 505(b)(2) regulatory pathway for a product candidate, we
cannot  assure  you  that  we  will  receive  the  requisite  or  timely  approvals  for  commercialization  of  such  product  candidate.  For  example,  we  had  under
development  a  patented  injectable  pentoxifylline  therapeutic  candidate,  which  we  believed  would  satisfy  the  requirements  of  the  505(b)(2)  regulatory
pathway.  However,  based  on  a  pre-IND  meeting  with  the  FDA  in  March  2018  to  discuss  the  clinical  and  regulatory  pathway  for  the  product,  we  have
decided  to  suspend  all  further  development  activities  for  this  candidate  indefinitely  due  to  extraordinarily  high  costs  of  the  clinical  trials  that  would  be
required by the FDA.

Notwithstanding  the  approval  of  many  products  by  the  FDA  pursuant  to  Section  505(b)(2),  over  the  last  few  years  some  pharmaceutical
companies  and  others  have  objected  to  the  FDA’s  interpretation  of  Section  505(b)(2)  to  allow  reliance  on  the  FDA’s  prior  findings  of  safety  and
effectiveness. If the FDA changes its interpretation of Section 505(b)(2), or if the FDA’s interpretation is successfully challenged in court, this could delay
or even prevent the FDA from approving any Section 505(b)(2) application that we submit. In addition, we expect that our competitors will file citizens’
petitions  with  the  FDA  in  an  attempt  to  persuade  the  FDA  that  our  product  candidate,  or  the  clinical  studies  that  support  their  approval,  contain
deficiencies. Such actions by our competitors could delay or even prevent the FDA from approving any NDA that we submit under Section 505(b)(2).

Moreover, the FDA recently adopted an interpretation of the three-year exclusivity provisions whereby a 505(b)(2) application can be blocked by
exclusivity  even  if  does  not  rely  on  the  previously  approved  drug  that  has  exclusivity  (or  any  safety  or  effectiveness  information  regarding  that  drug).
Under the FDA’s new interpretation, approval may be blocked by exclusivity awarded to a previously-approved drug product that shares certain innovative
features with our product, even if our 505(b)(2) application does not identify the previously-approved drug product as a listed drug or rely upon any of its
safety  or  efficacy  data.  Any  failure  to  obtain  regulatory  approval  of  our  product  candidates  would  significantly  limit  our  ability  to  generate  sufficient
revenues, and any failure to obtain such approval for all of the indications and labeling claims we deem desirable could reduce our potential revenues.

An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or prevent
the review or approval of our product candidate.

The  505(b)(2)  application  would  enable  us  to  reference  published  literature  or  the  FDA’s  previous  findings  of  safety  and  effectiveness  for  the
branded reference drug. For NDAs submitted under Section 505(b)(2) of the FDCA, the patent certification and related provisions of the Hatch-Waxman
Act apply. In accordance with Hatch-Waxman Act, in seeking approval for a drug through such an NDA, applicants are required to list with the FDA each
patent whose claims cover the applicant’s product. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the
FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. Drugs listed in the Orange Book can, in
turn, be cited by potential generic competitors in support of approval of an ANDA. An ANDA provides for marketing of a drug product that has the same
active  ingredients  in  the  same  strengths  and  dosage  form  as  the  listed  drug  and  has  been  shown  to  be  bioequivalent  to  the  listed  drug.  Other  than  the
requirement for bioequivalence testing, ANDA applicants are not required to conduct or submit results of pre-clinical or clinical tests to prove the safety or
effectiveness  of  their  drug  product.  Drugs  approved  in  this  way  are  commonly  referred  to  as  “generic  equivalents”  to  the  listed  drug  and  can  often  be
substituted by pharmacists under prescriptions written for the original listed drug.

21

 
 
 
 
 
 
 
 
The  ANDA  applicant  is  required  to  certify  to  the  FDA  concerning  any  patents  listed  for  the  approved  product  in  the  FDA’s  Orange  Book.
Specifically, the applicant must certify that either: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the listed
patent has not expired, but will expire on a particular date and approval is sought after patent expiration or (iv) the listed patent is invalid or will not be
infringed by the new product. The ANDA applicant may also elect to submit a section viii statement certifying that its proposed ANDA label does not
contain (or carves out) any language regarding the patented method-of-use rather than certify to a listed method-of-use patent. If the applicant does not
challenge the listed patents, the ANDA application will not be approved until all the listed patents claiming the referenced product have expired.

A  certification  that  the  new  product  will  not  infringe  the  already  approved  product’s  listed  patents,  or  that  such  patents  are  invalid  or
unenforceable, is called a Paragraph IV certification. If the ANDA applicant has provided a Paragraph IV certification to the FDA, the applicant must also
send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent
holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. Under the Hatch-Waxman Act, the holder
of patents that the 505(b)(2) application references may file a patent infringement lawsuit after receiving notice of the Paragraph IV certification. Filing of a
patent infringement lawsuit against the filer of the 505(b)(2) applicant within 45 days of the patent owner’s receipt of notice triggers a one-time, automatic,
30-month stay of the FDA’s ability to approve the 505(b)(2) NDA, unless patent litigation is resolved in favor of the Paragraph IV filer or the patent expires
before that time. Accordingly, we may invest a significant amount of time and expense in the development of one or more product candidates only to be
subject to significant delay and patent litigation before such product candidates may be commercialized, if at all.

In  addition,  a  505(b)(2)  application  will  not  be  approved  until  any  non-patent  exclusivity,  such  as  exclusivity  for  obtaining  approval  of  a  new
chemical entity listed in the Orange Book for the referenced product has expired. The FDA may also require us to perform one or more additional clinical
studies  or  measurements  to  support  the  change  from  the  branded  reference  drug,  which  could  be  time-consuming  and  could  substantially  delay  our
achievement of regulatory approvals for such product candidates. The FDA may also reject our future 505(b)(2) submissions and require us to file such
submissions under Section 505(b)(1) of the FDCA, which would require us to provide extensive data to establish safety and effectiveness of the drug for
the proposed use and could cause delay and be considerably more expensive and time-consuming. These factors, among others, may limit our ability to
successfully commercialize our product candidates.

Companies that produce branded reference drugs routinely bring litigation against ANDA or 505(b)(2) applicants that seek regulatory approval to
manufacture and market generic and reformulated forms of their branded products. These companies often allege patent infringement or other violations of
intellectual property rights as the basis for filing suit against an ANDA or 505(b)(2) applicant. Likewise, patent holders may bring patent infringement suits
against  companies  that  are  currently  marketing  and  selling  their  approved  generic  or  reformulated  products.  Litigation  to  enforce  or  defend  intellectual
property rights is often complex and often involves significant expense and can delay or prevent introduction or sale of our product candidates. If patents
are held to be valid and infringed by our product candidates in a particular jurisdiction, we would, unless we could obtain a license from the patent holder,
be required to cease selling in that jurisdiction and may need to relinquish or destroy existing stock in that jurisdiction. There may also be situations where
we use our business judgment and decide to market and sell our approved products, notwithstanding the fact that allegations of patent infringement(s) have
not  been  finally  resolved  by  the  courts,  which  is  known  as  an  “at-risk  launch.”  The  risk  involved  in  doing  so  can  be  substantial  because  the  remedies
available to the owner of a patent for infringement may include, among other things, damages measured by the profits lost by the patent owner and not
necessarily by the profits earned by the infringer. In the case of a willful infringement, the definition of which is subjective, such damages may be increased
up  to  three  times.  Moreover,  because  of  the  discount  pricing  typically  involved  with  bioequivalent  and,  to  a  lesser  extent,  505(b)(2)  products,  patented
branded  products  generally  realize  a  substantially  higher  profit  margin  than  bioequivalent  and,  to  a  lesser  extent,  505(b)(2)  products,  resulting  in
disproportionate damages compared to any profits earned by the infringer. An adverse decision in patent litigation could have a material adverse effect on
our business, financial position and results of operations and could cause the market value of our common stock to decline.

22

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

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

● demonstration of clinical safety and efficacy;

● relative convenience, dosing burden and ease of administration;

● the willingness of physicians to prescribe our product candidates, and the target patient population to try new therapies;

● efficacy of our product candidates compared to competing products;

● the introduction of any new products that may in the future become available targeting indications for which our product candidates may be

approved;

● new procedures or therapies that may reduce the incidences of any of the indications in which our product candidates may show utility;

● pricing and cost-effectiveness;

● the inclusion or omission of our product candidates in applicable therapeutic and vaccine guidelines;

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

● limitations or warnings contained in approved labeling from regulatory authorities;

● our  ability  to  obtain  and  maintain  sufficient  third-party  coverage  and  adequate  reimbursement  from  government  health  care  programs,
including Medicare  and  Medicaid,  private  health  insurers  and  other  third-party  payors  or  to  receive  the  necessary  pricing  approvals  from
government bodies regulating the pricing and usage of therapeutics; and

● the willingness  of  patients  to  pay  out-of-pocket  in  the  absence  of  third-party  coverage  or  adequate  reimbursement  or  government  pricing

approvals.

If any of our product 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 product candidates may require significant resources and may never be successful.

In addition, even if we obtain regulatory approvals for our product candidates, the timing or scope of any approvals may prohibit or reduce our
ability to commercialize our product 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  product  candidates  not  commercially  viable.  For  example,  regulatory
authorities may approve any of our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge
for any of our product candidates, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve any of our
product  candidates  with  a  label  that  does  not  include  the  labeling  claims  necessary  or  desirable  for  the  successful  commercialization  of  that  indication.
Further, the FDA or comparable foreign regulatory authorities may place conditions on approvals or require risk management plans or a REMS, to assure
the safe use of the drug. If the FDA concludes a REMS is needed, 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 product 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 product candidates.

We are subject to ongoing obligations and continued regulatory review, which may result in significant additional expense. Additionally, our product
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 product candidates.

The FDA or foreign equivalent may still impose significant restrictions on our products indicated uses 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  product  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, as well as continued compliance with current cGCP regulations for any clinical trials
that we conduct post-approval. 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  cGMP  requirements  relating  to  quality  control,  quality  assurance  and  corresponding
maintenance of records and documents.

The FDA has the authority to require a REMS as part of an NDA or after approval, which may impose further requirements or restrictions on the
distribution  or  use  of  an  approved  drug,  such  as  limiting  prescribing  to  certain  physicians  or  medical  centers  that  have  undergone  specialized  training,
limiting treatment to patients who meet certain safe-use criteria or requiring patient testing, monitoring and/or enrollment in a registry.

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.

24

 
 
 
 
 
 
 
In addition, if any of our product candidates are approved for a particular 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. However, companies may share truthful and not misleading information that is otherwise consistent with the product’s approved FDA labeling. If
we receive marketing approval for our product candidates, physicians may nevertheless legally prescribe our products to their patients in a manner that is
inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant liability and government
fines. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to
have improperly promoted off-label uses may be subject to significant sanctions. 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  discovers  previously  unknown  problems  with  a  product,  such  as  adverse  events  of  unanticipated  severity  or
frequency,  problems  with  the  facility  where  the  product  is  manufactured,  or  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;

● clinical holds;

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

● suspension or withdrawal of regulatory approval;

● 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 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 product 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.

Obtaining  foreign  regulatory  approvals  and  compliance  with  foreign  regulatory  requirements  could  result  in  significant  delays,  difficulties  and
costs  for  us  and  could  delay  or  prevent  the  introduction  of  our  products  in  certain  countries.  If  we  fail  to  comply  with  the  regulatory  requirements  in
international markets and/or to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential
of our product candidates will be harmed.

Significant additional labeling or warning requirements or limitations on the availability of our products may inhibit sales of affected products.

Various jurisdictions may seek to adopt significant additional product labeling or warning requirements or limitations on the availability of our
products relating to the content or perceived adverse health consequences of our products. Federal laws may preempt some or all of these attempts by state
or localities to impose additional labeling or warning requirements. If these types of requirements become applicable to our products under current or future
environmental or health laws or regulations, they may inhibit sales of our products. Moreover, if we fail to meet compliance deadlines for any such new
requirements,  our  products  may  be  deemed  misbranded  or  mislabeled  and  could  be  subject  to  enforcement  action,  or  we  could  be  exposed  to  private
lawsuits alleging misleading labels or product promotion.

Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product 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 health care system that could prevent or delay marketing approval for our product candidates, restrict or regulate post-approval activities and
affect our ability to profitably sell our product 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 product 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, the Medicare Modernization Act (“MMA”) changed the way Medicare covers and pays for pharmaceutical products. The
legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology based on average sales prices
for drugs. In addition, this legislation authorized 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. As a result of this legislation and the expansion of federal coverage of drug products, we expect that there will be
additional pressure to contain and reduce costs. These cost reduction initiatives and other provisions of this legislation could decrease the coverage and
price  that  we  receive  for  our  product  candidates  and  could  seriously  harm  our  business.  While  the  MMA  applies  only  to  drug  benefits  for  Medicare
beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates, and any reduction in
reimbursement that results from the MMA may result in a similar reduction in payments from private payors.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively
referred to as the Health Care Reform Law, was enacted, which substantially changes the way health care is financed by both governmental and private
insurers, and significantly impacts the U.S. pharmaceutical industry. The Health Care Reform Law, among other things, imposed reporting requirements on
manufacturers related to drug samples and financial relationships with physicians and teaching hospitals, increased the minimum Medicaid rebates owed by
manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations,
established annual fees on manufacturers of certain branded prescription drugs, and established a Medicare Part D coverage gap discount program.

26

 
 
 
 
 
 
 
 
Some of the provisions of the Health Care Reform Law have yet to be implemented, and there have been judicial and Congressional challenges to
certain aspects of the Health Care Reform Law, as well as recent efforts by the Trump administration to repeal or replace certain aspects of the Health Care
Reform Law. Since January 2017, former President Trump had signed two executive orders and other directives designed to delay, circumvent or loosen
certain requirements mandated by the Health Care Reform Law. Concurrently, Congress has considered legislation that would repeal or repeal and replace
all  or  part  of  the  Health  Care  Reform  Law. While  Congress  has  not  passed  comprehensive  repeal  legislation,  two  bills  affecting  the  implementation  of
certain taxes under the Health Care Reform Law have been signed into law. The Tax Act included a provision which repealed, effective January 1, 2019,
the  tax-based  shared  responsibility  payment  imposed  by  the  Health  Care  Reform  Law  on  certain  individuals  who  fail  to  maintain  qualifying  health
coverage  for  all  or  part  of  a  year  that  is  commonly  referred  to  as  the  “individual  mandate.”  On  January  22,  2018,  former  President  Trump  signed  a
continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain Health Care Reform Law-mandated fees, including
the so-called “Cadillac” tax on certain high-cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based
on market share, and the medical device excise tax on non-exempt medical devices. The Bipartisan Budget Act of 2018, among other things, amended the
Health Care Reform Law, effective January 1, 2019, to increase from 50% to 70% the point-of-sale discount that is owed by pharmaceutical manufacturers
who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. On December
14, 2018, a Texas U.S. District Court Judge ruled that the Health Care Reform Law is unconstitutional in its entirety because the “individual mandate” was
repealed  by  Congress  as  part  of  the  Tax  Act.  On  June  17,  2021,  the  U.S.  Supreme  Court  overturned  the  2018  Texas  U.S.  District  Court  decision.  It  is
unclear how subsequent appeals, and other efforts to repeal and replace the Health Care Reform will impact our business. We cannot predict the impact on
our business of changes to current laws and regulations. However, any changes that lower reimbursements for products for which we may obtain regulatory
approval, or that impose administrative and financial burdens on us, could adversely affect our business.

In addition, other legislative changes have been proposed and adopted in the United States since the Health Care Reform Law was enacted. These
changes include, among others, aggregate reductions of Medicare payments to providers of up to 2% per fiscal year. We expect that additional state and
federal health care reform measures will be adopted in the future, which may alter or completely replace the existing health care financing structure. Any of
these  reform  measures  could  limit  the  amounts  that  federal  and  state  governments  will  pay  for  health  care  products  and  services,  which  could  result  in
reduced demand for any such product candidate that we may have developed or additional pricing pressures on our business.

Further,  there  has  been  heightened  governmental  scrutiny  in  the  United  States  of  pharmaceutical  pricing  practices  in  light  of  the  rising  cost  of
prescription drugs and biologics. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation
designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs,
and reform government program reimbursement methodologies for products. For example, the Trump administration released a “Blueprint” to lower drug
prices and reduce out-of-pocket costs of drugs that contains additional proposals to increase drug manufacturer competition, increase the negotiating power
of  certain  federal  healthcare  programs,  incentivize  manufacturers  to  lower  the  list  price  of  their  products,  and  reduce  the  out-of-pocket  costs  of  drug
products  paid  by  consumers.  On  January  31,  2019,  the  U.S.  Department  of  Health  and  Human  Services,  Office  of  Inspector  General,  proposed
modifications to the federal Anti-Kickback Statute discount safe harbor for the purpose of reducing the cost of drug products to consumers which, among
other things, if finalized, will affect discounts paid by manufacturers to Medicare Part D plans, Medicaid managed care organizations and pharmacy benefit
managers working with these organizations. While some of these and other proposed measures may require additional authorization to become effective,
Congress  and  government  administration  officials  have  each  indicated  that  they  will  continue  to  seek  new  legislative  and/or  administrative  measures  to
control drug costs.

27

 
 
 
 
 
The policies of the FDA or similar regulatory authorities may change, and additional government regulations may be enacted that could prevent,
limit or delay regulatory approval of our product candidates. For example, in December 2016, the 21st Century Cures Act was signed into law. The 21st
Century Cures Act, among other things, is intended to modernize the regulation of drugs and biologics and spur innovation, but it has not yet been fully
implemented and its ultimate implementation is unclear. Furthermore, the Trump administration has taken several executive actions, including the issuance
of a number of executive orders, that could impose significant burdens on, or otherwise materially delay, the FDA’s ability to engage in routine regulatory
and  oversight  activities  such  as  implementing  statutes  through  rulemaking,  issuance  of  guidance  and  review  and  approval  of  marketing  applications.  If
these executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may
be negatively impacted. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are
not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve
or sustain profitability, which would adversely affect our business.

If we market our existing approved products or any of our new product candidates in a manner that violates health care 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 can be subject to significant liability.
Similarly,  industry  codes  in  the  EU  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 health care fraud and abuse
laws have been applied in recent years to restrict certain marketing practices in the pharmaceutical industry. These laws include, among others, 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 their exceptions and 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 health care item or service reimbursable under
Medicare,  Medicaid  or  other  federally  financed  health  care  programs.  This  statute  has  been  interpreted  broadly  to  apply  to  arrangements  between
pharmaceutical manufacturers on the one hand and prescribers, purchasers, formulary managers, and others on the other hand. Although there are several
statutory  exceptions  and  regulatory  safe  harbors  protecting  certain  common  activities  from  prosecution,  the  exceptions  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 exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does
not make the conduct per se illegal under the Federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case
basis  based  on  a  cumulative  review  of  all  of  its  facts  and  circumstances.  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, amended the intent requirement of the U.S. Anti-Kickback Statute and other criminal health care fraud statutes; a person or entity
no longer needs to have actual knowledge of the statutes or specific intent to violate them in order to have committed a violation. 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.

28

 
 
 
 
 
 
Over the past few years, several pharmaceutical and other health care 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  significant  administrative,  criminal,  and  civil  monetary
penalties, exclusion of a manufacturer’s products from reimbursement under government programs, fines and imprisonment. Due to the breadth of these
federal and state anti-kickback laws, and the potential for additional legal or regulatory change in this area, it is possible that our future business activities,
including our sales and marketing practices and/or our future relationships with physicians and the medical community might be challenged under anti-
kickback laws, which could harm us.

We are completely dependent on third parties to manufacture our approved products and new product candidates, and our commercialization of our
product  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 product 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 API in our product candidates for use in
our clinical trials or for commercial product, if any. In addition, we do not have the capability to encapsulate any of our product candidates as a finished
drug product for commercial distribution. As a result, we will be obligated to rely on contract manufacturers, if and when any of our product candidates are
approved for commercialization. While we have entered into certain agreements with contract manufacturers for clinical and commercial supply, there can
be no assurance we will be able to maintain those relationships or engage additional contract manufacturers for clinical or commercial supply of any of our
product candidates on favorable terms to us, or at all.

The  facilities  used  by  our  contract  manufacturers  to  manufacture  our  product  candidates  must  be  approved  by  the  FDA  or  comparable  foreign
regulatory authorities pursuant to inspections that will be conducted after we submit an NDA to the FDA or their equivalents to other relevant regulatory
authorities. We will not control the manufacturing process of, and will be completely dependent on, our contract manufacturing partners for compliance
with cGMPs for manufacture of both 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 product candidates. If our contract manufacturers do not 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 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  our
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 product 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 any of our product 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 any of our product 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 API or finished products or should cease doing business with us,
we could experience significant interruptions in the supply of any of our product candidates or may not be able to create a supply of our product candidates
at all. Were we to encounter manufacturing issues, our ability to produce a sufficient supply of any of our product 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 any of our product 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 any of our product candidates if we decided to transfer the manufacture of any of our product
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 contract manufacturer caused by problems at suppliers could delay shipment of Biorphen or any of our product candidates,
increase our cost of goods sold and result in lost sales.

We cannot guarantee that our future manufacturing and supply partners will be able to reduce the costs of commercial-scale manufacturing of any
of our product candidates over time. If the commercial-scale manufacturing costs of any of our product 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.

We may not be able to establish agreements with third parties with whom we wish to collaborate and, if we are able to establish them, we may not be
able to establish them on commercially reasonable terms, which could result in alterations or delays of our development and commercialization plans.

We  face  significant  competition  in  seeking  appropriate  third  parties  to  assist  us  in  our  business  operations.  Whether  we  reach  a  definitive
agreement will depend, among other things, upon our assessment of the third parties’ resources and expertise, the terms and conditions of the proposed
agreement, and the proposed parties’ evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of
approval by the FDA or similar regulatory authorities outside the United States, the potential market for the product candidate, the costs and complexities
of  manufacturing  and  delivering  the  product  candidate  to  patients,  the  potential  of  competing  products,  the  existence  of  uncertainty  with  respect  to  our
ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge and industry and market
conditions generally. Potential third parties may also consider alternative product candidates or technologies for similar indications that may be available to
collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. The terms of any arrangements
that we may establish may also not be favorable to us.

30

 
 
 
 
 
 
 
Agreements with third parties are complex and time-consuming to negotiate and document. In addition, there have been a significant number of
recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future third parties to assist us in
our business operations. We may not be able to negotiate agreements on a timely basis, on acceptable terms or at all. If we are unable to do so, we may
have  to  curtail  the  development  of  the  product  candidate,  reduce  or  delay  its  development  program,  delay  its  potential  commercialization  or  reduce  the
scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If
we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may
not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidate or bring
it to market and generate product revenue.

In addition, any future agreements that we enter into may not be successful. The success of our arrangements will depend heavily on the efforts
and  activities  of  our  third-party  collaborators.  Collaborators  generally  have  significant  discretion  in  determining  the  efforts  and  resources  that  they  will
apply to these collaborations. Disagreements between parties to an agreement regarding clinical development and commercialization matters can lead to
delays  in  the  development  process  or  commercializing  the  applicable  product  candidate  and,  in  some  cases,  termination  of  the  agreement.  These
disagreements can be difficult to resolve if neither of the parties has final decision-making authority. Collaborations with pharmaceutical or biotechnology
companies and other third parties often are terminated or allowed to expire by the other party. Any such termination or expiration would adversely affect us
financially and could harm our business reputation.

We may need to rely on third parties to conduct clinical trials for our future product 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 any of our product candidates
and our business would be substantially harmed.

We have entered into agreements with third-party CROs to conduct and manage our clinical programs including contracting with clinical sites to
perform  our  clinical  studies.  We  plan  to  rely  heavily  on  these  parties  for  execution  of  clinical  studies  for  our  product  candidates  and  will  control  only
certain aspects of their activities. 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 and comparable foreign regulatory authorities
for  any  products  in  clinical  development.  The  FDA  and  its  foreign  equivalents  enforce  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 or other regulatory authorities 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.

Although we intend to design the clinical trials for our product candidates in consultation with CROs, we expect that the CROs will manage all of
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,  breach  their  obligations  to  us  or  fail  to  comply  with
regulatory  requirements,  the  development  and  commercialization  of  any  of  our  product  candidates  for  the  subject  indication  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 any of our product 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.

31

 
 
 
 
 
 
 
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 product candidates. As a result, our financial results and the commercial prospects for any of our product candidates would be harmed,
our costs could increase and our ability to generate revenue could be delayed.

We enter into various contracts in the normal course of our business, some or all of which may require us to indemnify the other party to the contract.
In the event we have to perform under these indemnification provisions, it could have an adverse effect on our business, financial condition and results
of operations.

In the normal course of business, we periodically may enter into commercial, service, collaboration, licensing, consulting and other agreements
that contain indemnification provisions. With respect to our commercial agreements, vendors typically ask for indemnification from any third-party product
liability  claims  that  could  result  from  the  production,  use  or  consumption  of  the  product,  as  well  as  for  alleged  infringements  of  any  patent  or  other
intellectual property right by a third party. Should our obligation under an indemnification provision exceed applicable insurance coverage or if we were
denied insurance coverage, our business, financial condition and results of operations could be adversely affected. Similarly, if we are relying on a third
party to indemnify us and the party is denied insurance coverage, or the indemnification obligation exceeds the applicable insurance coverage and does not
have other assets available to indemnify us, our business, financial condition and results of operations could be adversely affected.

Any termination or suspension of, or delays in the commencement or completion of, any necessary studies of any of our product 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 or a comparable foreign regulatory authority failing to grant permission to proceed and placing the clinical study on hold;

● subjects for clinical testing failing to enroll or remain in our trials at the rate we expect;

● a facility manufacturing any of our product 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
candidates 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  product  candidates,  or  participating  in

competing clinical studies;

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

● reports from clinical testing on 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,  cGMP  requirements,  or  other  third  parties  not
performing data collection and analysis in a timely or accurate manner;

32

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● inspections of clinical study sites by the FDA, comparable foreign regulatory authorities, 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;

● 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; and

● government or regulatory delays or “clinical holds” requiring suspension or termination of a trial.

Product development costs for any of our product 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, comparable foreign regulatory authorities, 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, the IRB, or other reviewing entities, or any of our clinical study sites suspend or terminate any of our clinical studies of any of
our product candidates, its commercial prospects may be materially harmed and our ability to generate sufficient 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 generate
sufficient 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 product 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 any of our product candidates could be significantly reduced.

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 of drug product candidates 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. 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 or comparable foreign regulatory authorities will view the results as we do or that any future trials
of any of our product 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 biopharmaceutical 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 product candidates may not be successful.

33

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, a number of factors could contribute to a lack of favorable safety and efficacy results for any of our product candidates. For example,
such  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.

We may need to conduct clinical trials for our new product candidates and we may be delayed in commercializing or fail to find success in these
trials. Further, the results of any clinical trial may not be predictive of future trial results. Positive results in preclinical testing and early clinical trials do not
ensure that later clinical trials will be successful. A number of pharmaceutical companies have suffered significant setbacks in clinical trials, including in
Phase 3, after promising results in preclinical testing and early clinical trials. These setbacks have included negative safety and efficacy observations in
later clinical trials, including previously unreported adverse events.

Phase 3 clinical trials often produce unsatisfactory results even though prior clinical trials were successful. Moreover, the results of clinical trials
may be unsatisfactory to the FDA or foreign regulatory authorities even if we believe those clinical trials to be successful. The FDA or applicable foreign
regulatory agencies may suspend one or all of our clinical trials or require that we conduct additional clinical, nonclinical, manufacturing, validation or
drug product quality studies and submit that data before considering or reconsidering any NDA or similar foreign regulatory application we may submit.
Depending on the extent of these additional studies, approval of any applications that we submit may be significantly delayed or may require us to expend
more resources than we have available. It is also possible that additional studies we conduct may not be considered sufficient by the FDA or applicable
foreign regulatory agencies to provide regulatory approval.

If any of these outcomes occur, we may not receive approval for our product candidate.

We are subject to extensive laws and regulations related to data privacy, and our failure to comply with these laws and regulations could harm our
business.

We are subject to data privacy and security laws and regulations by both the federal government and the states in which we conduct our business.
HIPAA and their respective implementing regulations, including the Final Omnibus Rule published on January 25, 2013, govern our processing of personal
data, including the collection, access, use, analysis, modification, storage, transfer, security breach notification, destruction and disposal of personal data.
There are foreign and state law versions of these laws and regulations to which we are currently and/or may in the future, be subject. For example, the
collection and use of personal health data in the European Union is governed by the GDPR. The GDPR, which is wide-ranging in scope, imposes several
requirements  relating  to  the  consent  of  the  individuals  to  whom  the  personal  data  relates,  the  information  provided  to  the  individuals,  the  security  and
confidentiality of the personal data, data breach notification and the use of third-party processors in connection with the processing of personal data. The
GDPR also imposes strict rules on the transfer of personal data out of the European Union to the United States, provides an enforcement authority and
imposes  large  monetary  penalties  for  noncompliance.  The  GDPR  requirements  apply  not  only  to  third-party  transactions,  but  also  to  transfers  of
information within our company, including employee information.

In the United States, there are numerous privacy laws that may be applicable to our activities, and a range of enforcement agencies at both the
state and federal levels that can review companies for privacy and data security concerns based on general consumer protection laws. New laws also are
being considered or have been implemented at both the state and federal levels. For example, the California Consumer Privacy Act of 2018 (effective on
January 1, 2020), as amended by the California Privacy Rights and Enforcement Act of 2020 (effective on January 1, 2023) (“CCPA”), requires companies
that process information of California residents (“consumers,” as defined under the CCPA) to make specific disclosures about their data collection, use and
disclosure  practices,  provides  consumers  with  individual  data  privacy  rights,  including  enabling  consumers  to  limit  the  use  of  their  sensitive  personal
information, imposes new operational requirements for covered businesses, imposes data retention limitations, provides a private right of action for data
breaches, creates a statutory damages framework and creates a new state agency, the California Privacy Protection Agency, that is vested with the authority
to implement and enforce the CCPA. Although there are limited exemptions for clinical trial data under the CCPA, the CCPA and other similar laws could
impact our business activities in the future depending on our revenue growth, how much consumer data we process, and how such laws are interpreted.
Additionally, four additional states have enacted privacy laws, which could increase our potential liability and adversely affect our business in the future. In
particular,  the  Virginia  Consumer  Data  Protection  Act  (“VCDPA”)  became  effective  on  January  1,  2023;  the  Colorado  Privacy  Act  (“CPA”)  and  the
Connecticut Data Privacy Act (“CTDPA”) will become effective on July 1, 2023; and the Utah Consumer Privacy Act (“UCPA”) will become effective on
December  31,  2023.  While  these  regulations  incorporate  many  similar  concepts  to  the  CCPA,  there  are  also  several  key  differences  in  their  scope,
application,  and  enforcement  that  will,  among  other  things,  impact  how  regulated  businesses  collect  and  process  personal  sensitive  data,  conduct  data
protection assessments, transfer personal data to affiliates, and respond to consumer rights requests. Other states are considering similar legislation and a
broad range of legislative measures also have been introduced at the federal level. Such proposed legislation, if enacted, may add additional complexity,
variation in requirements, restrictions and potential legal risk, require additional investment of resources in compliance programs, impact strategies and the
availability of previously useful data and could result in increased compliance costs and/or changes in business practices and policies. The existence of
comprehensive privacy laws in different states in the country makes our compliance obligations more complex and costly and may increase the likelihood
that we may be subject to enforcement actions or otherwise incur liability for noncompliance.

34

 
 
 
 
 
 
 
 
 
Further, regulations promulgated pursuant to HIPAA imposes privacy, security and breach notification obligations on certain healthcare providers,
health  plans,  and  healthcare  clearinghouses,  known  as  covered  entities,  as  well  as  their  business  associates  that  perform  certain  services  that  involve
creating,  receiving,  maintaining  or  transmitting  individually  identifiable  health  information  for  or  on  behalf  of  such  covered  entities,  and  their  covered
subcontractors.  HIPAA  establishes  privacy  and  security  standards  that  limit  the  use  and  disclosure  of  individually  identifiable  health  information  and
protected health information, or PHI, and requires the implementation of administrative, physical, and technological safeguards to protect the privacy of
PHI and ensure the confidentiality, integrity, and availability of electronic PHI. Most healthcare providers, including research institutions from which we
obtain patient health information, are subject to privacy and security regulations promulgated under HIPAA. We do not believe that we are currently acting
as  a  covered  entity  or  business  associate  under  HIPAA  and  thus  are  not  directly  subject  to  its  requirements  or  penalties.  However,  any  person  may  be
prosecuted under HIPAA’s criminal provisions either directly or under aiding-and-abetting or conspiracy principles. Consequently, depending on the facts
and circumstances, we could face substantial criminal penalties if we knowingly receive individually identifiable health information from a HIPAA-covered
healthcare provider or research institution that has not satisfied HIPAA’s requirements for disclosure of individually identifiable health information.

The  global  legislative  and  regulatory  landscape  for  privacy  and  data  protection  continues  to  evolve,  and  implementation  standards  and
enforcement practices are likely to remain uncertain for the foreseeable future. This evolution may create uncertainty in our business, result in liability or
impose additional costs on us. The cost of compliance with these laws, regulations and standards is high and is likely to continue to increase in the future.

It is possible that privacy laws may be interpreted and applied in a manner that is inconsistent with our practices. Any failure or perceived failure
by us to comply with federal, state, or foreign laws or self-regulatory standards could result in negative publicity, diversion of management time and effort
and proceedings against us by governmental entities or others. In many jurisdictions, enforcement actions and consequences for noncompliance are rising.
As  we  continue  to  expand  into  other  foreign  countries  and  jurisdictions,  we  may  be  subject  to  additional  laws  and  regulations  that  may  affect  how  we
conduct business.

In  addition  to  the  risks  associated  with  enforcement  activities  and  potential  contractual  liabilities,  our  ongoing  efforts  to  comply  with  evolving
laws and regulations at the federal and state level may be costly and require ongoing modifications to our policies, procedures and systems. Further, any
failure by our third-party collaborators, service providers, contractors or consultants to comply with applicable law, regulations or contractual obligations
related to data privacy or security could result in proceedings against us by governmental entities or others.

We may also publish privacy policies and other documentation regarding our collection, processing, use and disclosure of personal information
and/or other confidential information. Although we endeavor to comply with applicable regulations, our published policies and other documentation, we
may  at  times  fail  to  do  so  or  may  be  perceived  to  have  failed  to  do  so.  Despite  our  efforts,  we  may  not  be  successful  in  achieving  compliance  if  our
employees or vendors fail to comply with our published policies and documentation. Such failures can subject us to potential international, local, state and
federal action if they are found to be deceptive, unfair, or misrepresentative of our actual practices. Claims that we have violated individuals’ privacy rights
or failed to comply with data protection laws or applicable privacy notices, even if we are not found liable, could be expensive and time-consuming to
defend and could result in adverse publicity that could harm our business. We also face a threat of consumer class actions related to these laws and the
overall protection of personal information. Even if we are not determined to have violated these laws, government investigations into these issues typically
require  the  expenditure  of  significant  resources  and  generate  negative  publicity,  which  could  harm  our  reputation  and  our  business,  financial  condition,
results of operations or prospects.

35

 
 
 
 
 
 
 
Risks Relating to Our Intellectual Property Rights

We  will  depend  on  rights  to  certain  pharmaceutical  compounds  that  have  been  acquired  by  us.  We  do  not  have  complete  control  over  these
pharmaceutical compounds and any loss of our rights to them could prevent us from selling our products.

We  are  dependent  on  the  assignment  and  licensing  from  third  parties  for  certain  of  our  pharmaceutical  compounds  and  potential  product
candidates. Our rights to use the pharmaceutical compounds we were assigned are subject to the negotiation of, continuation of and compliance with the
terms of those assignments and licenses. Moreover, under these agreements, any related patents may remain under the control of the assignor or licensor.
Our rights to develop and commercialize the product candidates are subject to the validity of the intellectual property rights. Enforcement of any assigned
or licensed patents or defense or any claims asserting the invalidity of these patents is often subject to the control or cooperation of the assignor or licensor.
Legal action could be initiated against the original owners of the intellectual property that we acquired and an adverse outcome in such legal action could
harm our business because it might prevent such companies or institutions from continuing to assign intellectual property that we may need to operate our
business.

In addition, our rights to practice the inventions claimed in any patents and patent applications are subject to our assignors and licensors abiding
by the terms of those agreements and not terminating them. These agreements may be terminated by the assignor or licensor if we are in material breach of
certain terms or conditions of the agreement or in certain other circumstances. Our rights under these agreements are subject to our continued compliance
with the terms of the agreements, including the payment of royalties and other payment due under the agreements. Termination of these agreements could
prevent us from marketing some or all of our products. Because of the complexity of our products and the patents, determining the scope of the assignment
or license and related royalty obligations can be difficult and can lead to disputes between us and the assignor or licensor. An unfavorable resolution of
such a dispute could lead to an increase in the royalties payable pursuant to the agreement. If the assignor or licensor believed we were not paying the
royalties due under the agreement or were otherwise not in compliance with the terms of the agreement, the assignor or licensor might attempt to revoke the
agreement. If such an attempt were successful, we might be barred from producing and selling some or all of our products.

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

Our  commercial  success  will  depend,  in  part,  on  obtaining  and  maintaining  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 or enforceable in our patents. Patent and patent applications relating to our
product candidates and related technologies may be challenged, invalidated or circumvented by third parties and might not protect us against competitors
with similar products or technologies.

The degree of future protection for our proprietary rights is uncertain, because legal means afford only limited protection and may not adequately
protect our rights, 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 any of our product
candidates,  or  important  to  our  business.  We  cannot  be  certain  that  any  patent  application  owned  by  a  third  party  will  not  have  priority  over  patent
applications filed by us, or that we will not be involved in interference, opposition or invalidity proceedings before U.S. or foreign patent offices.

36

 
 
 
 
 
 
 
 
 
Additionally,  if  we  or  one  of  our  licensing  partners  initiated  legal  proceedings  against  a  third  party  to  enforce  a  patent  covering  any  product
candidate, the defendant could counterclaim that the patent covering any other product candidate is invalid and/or unenforceable. In patent litigation in the
United  States,  defendant  counterclaims  alleging  invalidity  and/or  unenforceability  are  commonplace.  Grounds  for  a  validity  challenge  include  alleged
failures to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Grounds for unenforceability assertions
include  allegations  that  someone  connected  with  prosecution  of  the  patent  withheld  relevant  information  from  the  U.S.  Patent  and  Trademark  Office
(“USPTO”), or made a misleading statement, during prosecution. Third parties may also raise similar claims before administrative bodies in the United
States or abroad, even outside the context of litigation. Such mechanisms include re-examination, post grant review and equivalent proceedings in foreign
jurisdictions, e.g., opposition proceedings. Such proceedings could result in revocation or amendment of our patents or our licensors’ patents in such a way
that  they  no  longer  cover  product  candidates  or  competitive  products.  The  outcome  following  legal  assertions  of  invalidity  and  unenforceability  is
unpredictable. With respect to validity, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were
unaware  during  prosecution.  If  a  defendant  were  to  prevail  on  a  legal  assertion  of  invalidity  and/or  unenforceability,  we  would  lose  at  least  part,  and
perhaps all, of the patent protection on any product candidate. Such a loss of patent protection would have a material adverse impact on our business.

In  the  future,  we  may  rely  on  know-how  and  trade  secrets  to  protect  technology,  especially  in  cases  when  we  believe  patent  protection  is  not
appropriate or obtainable. However, know-how and trade secrets are difficult to protect. While we intend to 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.

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

Filing,  prosecuting  and  defending  patents  on  product  candidates  in  all  countries  and  jurisdictions  throughout  the  world  would  be  prohibitively
expensive, and our intellectual property rights in some countries outside the United States could be less extensive than those offered in the United States.
Consequently,  we  may  not  be  able  to  prevent  third  parties  from  practicing  our  inventions  in  all  countries  outside  the  United  States,  or  from  selling  or
importing products made using our inventions in and into the United States or other jurisdictions.

Competitors may use our technologies in jurisdictions where we do not have, or where we do not pursue and obtain, patent protection to develop
their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as
that  in  the  United  States.  These  products  may  compete  with  our  product  and  our  patents  or  other  intellectual  property  rights  may  not  be  effective  or
sufficient to prevent them from competing. Even if we pursue and obtain issued patents in particular jurisdictions, our patent claims or other intellectual
property rights may not be effective or sufficient to prevent third parties from so competing.

Further, the laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the United States. Many
companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems
of some countries, particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those
relating  to  biotechnology.  This  could  make  it  difficult  for  us  to  stop  the  infringement  of  our  patents,  if  obtained,  or  the  misappropriation  of  our  other
intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third
parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In
these  countries,  patents  may  provide  limited  or  no  benefit.  Patent  protection  must  ultimately  be  sought  on  a  country-by-country  basis,  which  is  an
expensive and time-consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we
will not have the benefit of patent protection in such countries.

37

 
 
 
 
 
 
 
Moreover, proceedings to enforce our patent rights, or those of our licensors or partners, in foreign jurisdictions could result in substantial costs
and divert our efforts and attention from other aspects of our business, could put our in-licensed patents, or any patents that we may own in the future, at
risk  of  being  invalidated  or  interpreted  narrowly,  could  put  our  owned  or  in-licensed  patent  applications  at  risk  of  not  issuing  and  could  provoke  third
parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be
commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant
commercial advantage from the intellectual property that we develop or license.

If we fail to obtain or maintain patent protection or trade secret protection for our product candidates 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.

Changes in either U.S. or foreign patent law or interpretation of such laws could diminish the value of patents in general, thereby impairing our ability
to protect our products.

As is the case with other biotechnology companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and
enforcing patents in the biotechnology industry involve both technological and legal complexity, and it therefore is costly, time-consuming and inherently
uncertain.  In  addition,  on  September  16,  2011,  the  Leahy-Smith  America  Invents  Act  (“AIA”),  was  signed  into  law.  The  AIA  includes  a  number  of
significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted and may also affect patent litigation.

An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” system for deciding
which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention. A third party that
files a patent application in the U.S. PTO after that date but before us could therefore be awarded a patent covering an invention of ours even if we had
made the invention before it was made by the third party. This will require us to be cognizant going forward of the time from invention to filing of a patent
application.

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and providing
opportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our U.S. patents, even those issued before March 16,
2013. Because of a lower evidentiary standard necessary to invalidate a patent claim in the USPTO proceedings compared to the evidentiary standard in
U.S. federal court, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though
the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the
USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district
court action.

Depending  on  decisions  by  the  U.S.  Congress,  the  federal  courts,  the  USPTO,  or  similar  authorities  in  foreign  jurisdictions,  the  laws  and
regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing in-licensed
patents and patents that we might obtain in the future.

38

 
 
 
 
 
 
 
 
 
 
Our 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 any of our product candidates or any future product candidate.
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 any of our 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.

Third parties may hold proprietary rights that could prevent any of our product candidates from being marketed. Any patent-related legal action
against  us  claiming  damages  and  seeking  to  enjoin  commercial  activities  relating  to  any  of  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 any of our product candidates or any future 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 our product candidates or any future 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 any of our product candidates or a future product candidate, which
could harm our business, financial condition and operating results.

We expect that there are other companies, including major pharmaceutical companies, working in the areas competitive to our proposed product
candidates which either has resulted, or may result, in the filing of patent applications that may be deemed related to our activities. If we were to challenge
the validity of these or any issued U.S. patent in court, we would need to overcome a statutory presumption of validity that attaches to every issued U.S.
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 U.S. patent in an administrative trial before the Patent Trial and Appeal Board in the USPTO, 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.

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Others may claim an ownership interest in our intellectual property, which could expose us to litigation and have an adverse effect on our prospects.

A third party may claim an ownership interest in one or more of our or our licensors’ patents or other proprietary or intellectual property rights. A
third  party  could  bring  legal  actions  against  us  and  seek  monetary  damages  and/or  enjoin  clinical  testing,  manufacturing  and  marketing  of  the  affected
product or products. We cannot guarantee that a third party will not assert a claim or an interest in any of such patents or intellectual property. If we become
involved  in  any  litigation,  it  could  consume  a  substantial  portion  of  our  resources,  and  cause  a  significant  diversion  of  effort  by  our  technical  and
management personnel. If any of these actions are successful, in addition to any potential liability for damages, we could be required to obtain a license to
continue to manufacture or market the affected product, in which case we may be required to pay substantial royalties or grant cross-licenses to our patents.
We  cannot,  however,  assure  you  that  any  such  license  will  be  available  on  acceptable  terms,  if  at  all.  Ultimately,  we  could  be  prevented  from
commercializing a product candidate, or be forced to cease some aspect of our business operations as a result of claims of patent infringement or violation
of other intellectual property rights. Further, the outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in
advance, including the demeanor and credibility of witnesses and the identity of any adverse party. This is especially true in intellectual property cases that
may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree.

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 will 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.

Risks Related to Owning Our Common Stock

An active, liquid and orderly trading market for our shares may not continue to be developed or sustained.

Our common stock is listed on the Nasdaq Global Market. However, trading volume has been limited and a more active public market for our
common stock may not develop or be sustained over time. The market price of our common stock could be subject to significant fluctuations. The price of
our  stock  may  change  in  response  to  variations  in  our  operating  results  and  also  may  change  in  response  to  other  factors,  including  factors  specific  to
companies in our industry many of which are beyond our control. Our shares may be less liquid than the shares of other public companies and there may be
imbalances between supply and demand for our shares. As a result, our share price may experience significant volatility and may not necessarily reflect the
value  of  our  expected  performance.  Moreover,  sales  of  our  common  stock  in  the  public  market,  or  the  perception  that  such  sales  could  occur,  could
negatively  impact  the  price  of  our  common  stock.  As  a  result,  you  may  not  be  able  to  sell  your  shares  of  our  common  stock  in  short  time  periods,  or
possibly at all, and the price per share of our common stock may fluctuate significantly.

40

 
 
 
 
 
 
 
 
 
Future capital raises may dilute our existing stockholders’ ownership, could depress the market price for our common stock and have other adverse
effects on our operations.

We  have  an  effective  Form  S-3  registration  statement  (“Shelf  Registration”)  on  file  with  the  SEC  which  allows  us  to  sell  any  combination  of
common stock, preferred stock, debt securities, warrants to purchase any of these securities, subscription rights to purchase any of these securities, and/or
units consisting of one or more of the foregoing in one or more offerings up to a total dollar amount of $100 million (including the $22.5 million raised in
our October 2020 offering of common stock). The issuance of additional shares of our common stock pursuant to the Shelf Registration, or issuances of
securities  convertible  into  or  exercisable  for  our  common  stock  or  other  equity-linked  securities,  including  preferred  stock,  warrants,  debt  securities  or
units, would dilute the ownership interest of our common shareholders and could depress the market price of our common stock and impair our ability to
raise capital through the sale of additional equity securities. 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.

The trading price of the shares of our common stock may continue to be volatile, and purchasers of our common stock could incur substantial losses.

The trading price of our common stock has fluctuated significantly in the past and is likely to be volatile. The stock market in general, and early
stage  public  companies  in  particular,  has  experienced  extreme  price  and  volume  fluctuations  that  have  often  been  unrelated  or  disproportionate  to  the
operating performance of such companies. The stock market in general has been, and the market price of our shares in particular will likely be, subject to
fluctuation, whether due to, or irrespective of, our operating results and financial condition. The market price of our shares on the Nasdaq Global Market
may fluctuate as a result of a number of factors, some of which are beyond our control, including, but not limited to:

● actual or anticipated variations in our and our competitors’ results of operations and financial condition;

● market acceptance of our products;

● the mix of products that we sell and related services that we provide;

● changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;

● not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley

Act”);

● changes in earnings estimates or recommendations by securities analysts, if our shares are covered by analysts;

● development of technological innovations or new competitive products by others;

● announcements of technological innovations or new products by us;

● publication of the results of preclinical or clinical trials for our other product candidates;

● failure by us to achieve a publicly announced milestone;

● delays between our expenditures to develop and market new or enhanced products and the generation of sales from those products;

● developments concerning intellectual property rights, including our involvement in litigation brought by or against us;

● regulatory developments and the decisions of regulatory authorities as to the approval or rejection of new or modified products;

● changes in the structure of healthcare payment systems;

● changes in the amounts that we spend to develop, acquire or license new products, technologies or businesses;

● changes in our expenditures to promote our products;

● our sale or proposed sale, or the sale by our significant stockholders, of our shares or other securities in the future;

● changes in key personnel;

● success or failure of our research and development projects or those of our competitors;

● the trading volume of our shares; and

● general economic and market conditions and other factors, including factors unrelated to our operating performance.

These factors and any corresponding price fluctuations may materially and adversely affect the market price of our shares and result in substantial
losses being incurred by our investors. In the past, following periods of market volatility, public company stockholders have often instituted securities class
action  litigation.  If  we  were  involved  in  securities  litigation,  it  could  impose  a  substantial  cost  upon  us  and  divert  the  resources  and  attention  of  our
management from our business.

We are an “emerging growth company” under the JOBS Act of 2012 and we cannot be certain if the reduced disclosure requirements applicable to
emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”), and we may take advantage
of  certain  exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  “emerging  growth  companies”
including, but not limited to:

● not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley

Act”);

● reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements;

● exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden

parachute payments; and

● extended transition periods available for complying with new or revised accounting standards.

We have chosen to “opt out” of the extended transition periods available for complying with new or revised accounting standards, but we intend to
take advantage of all of the other benefits available under the JOBS Act, including the exemptions discussed above. We cannot predict if investors will find
our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may
be a less active trading market for our common stock and our stock price may be more volatile.

We will remain an “emerging growth company” for up to five years from the end of the fiscal year following the fifth anniversary of the date of
the first sale of our common stock pursuant to an effective registration statement filed under the Securities Act, which will be December 31, 2023. We will
lose that status sooner, however, if our revenues exceed $1.07 billion, if we issue more than $1 billion in non-convertible debt in a three-year period or if
the market value of our common stock that is held by non-affiliates exceeds $700 million as of any June 30.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or
prevent  fraud.  As  a  result,  stockholders  could  lose  confidence  in  our  financial  and  other  public  reporting,  which  would  harm  our  business  and  the
trading price of our common shares.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure
controls and procedures, are designed to 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. In addition, any testing by us conducted in connection with Section 404 of the
Sarbanes-Oxley Act, or the subsequent testing by our independent registered public accounting firm when required, may reveal deficiencies in our internal
controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retrospective changes to our consolidated
financial statements or identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in
our reported financial information, which could have a negative effect on the trading price of our common shares. There is also a risk that neither we nor
our independent registered public accounting firm (when applicable in the future) will be able to conclude within the prescribed timeframe that internal
controls over financial reporting is effective as required by Section 404. This could result in an adverse reaction in the financial markets due to a loss of
confidence in the reliability of our financial statements.

Our status as an “emerging growth company” under the JOBS Act may make it more difficult to raise capital as and when we need it.

Because of the exemptions from various reporting requirements provided to us as an “emerging growth company,” we may be less attractive to
investors and it may be difficult for us to raise additional capital as and when we need it. Investors may be unable to compare our business with other
companies in our industry if they believe that our reporting is not as transparent as other companies in our industry. If we are unable to raise additional
capital as and when we need it, our financial condition and results of operations may be materially and adversely affected.

We have not paid dividends in the past and have no immediate plans to pay dividends, so any returns will be limited to the value of our stock.

We plan to reinvest all of our earnings, to the extent we have earnings, to cover operating costs and otherwise become and remain competitive. We
do not plan to pay any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that we would, at any time, generate
sufficient  surplus  cash  that  would  be  available  for  distribution  to  the  holders  of  our  common  stock  as  a  dividend.  Therefore,  you  should  not  expect  to
receive cash dividends on our common stock, and any return to stockholders will therefore be limited to the appreciation of their stock.

43

 
 
 
 
 
 
 
 
 
 
If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our shares, the
price of our shares could decline.

The trading market for our shares will rely in part on the research and reports that equity research analysts publish about us and our business, if at
all. We do not have control over these analysts, and we do not have commitments from them to write research reports about us. The price of our shares
could decline if no research reports are published about us or our business, or if one or more equity research analysts downgrades our shares or if those
analysts issue other unfavorable commentary or cease publishing reports about us or our business.

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

Our federal net operating losses (“NOLs”) generated in taxable years ending prior to 2018 could expire unused. Under the Tax Act, federal NOLs
incurred in taxable years ending after December 31, 2017, may be carried forward indefinitely, but the deductibility of federal NOLs generated in tax years
beginning before December 31, 2017, is limited. We filed in GA, IL, MN and TN for 2021. Only GA conforms to the Tax Act. IL and TN do not conform
(their NOL will expire if not used and there is no limit deduction on their NOL). MN does conform with the 80% of taxable income limitation section of
the Tax Act but not the indefinite carryforward section. MN NOL will expire if not used. In addition, under Sections 382 and 383 of the Internal Revenue
Code of 1986, as amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a
greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards, or
NOLs, and other pre-change tax attributes (such as research tax credits) to offset its post-change income may be limited. We are performing a study to
determine  if  we  have  triggered  any  “ownership  change”  limitations.  We  may  also  experience  ownership  changes  in  the  future  as  a  result  of  subsequent
shifts in our stock ownership some of which may be outside of our control. As a result, if we earn net taxable income, our ability to use our pre-ownership
change  NOL  carryforwards  to  offset  U.S.  federal  taxable  income  may  be  subject  to  limitations,  which  could  potentially  result  in  increased  future  tax
liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate
or permanently increase state taxes owed.

Assuming a market for our common stock continues to develop, sales of a substantial number of shares of our common stock in the public market by
our existing stockholders could cause our stock price to fall.

Sales of a substantial number of shares of our common stock by our existing stockholders in the public market or the perception that these sales
might  occur,  could  depress  the  market  price  of  our  common  stock  and  could  impair  our  ability  to  raise  capital  through  the  sale  of  additional  equity
securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock.

As of March 7, 2023, we had 25,458,057 shares of common stock outstanding, all of which, other than shares held by our directors and certain
officers, are eligible for sale in the public market, subject in some cases to compliance with the requirements of Rule 144, including volume limitations and
manner of sale requirements.

Certain holders of our securities are entitled to rights with respect to the registration of their shares under the Securities Act of 1933, as amended
(the “Securities Act”). Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the
Securities Act. Any sales of securities by these stockholders could have a material adverse effect on the trading price of our common stock.

We may be at an increased risk of securities class action litigation.

Historically, securities class action litigation has often been brought against a company following a decline in the market price of its securities.
This risk is especially relevant for us because biotechnology and pharmaceutical companies have experienced significant stock price volatility in recent
years. If we were to be sued, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

Our charter documents and Delaware law may inhibit a takeover that stockholders consider favorable.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws and applicable provisions of Delaware law
may  delay  or  discourage  transactions  involving  an  actual  or  potential  change  in  control  or  change  in  our  management,  including  transactions  in  which
stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests.
The provisions in our amended and restated certificate of incorporation and amended and restated bylaws:

● authorize our board of directors to issue, without further action by the stockholders, shares of undesignated preferred stock with terms, rights and

preferences determined by our board of directors that may be senior to our common stock;

● establish  an  advance  notice  procedure  for  stockholder  proposals  to  be  brought  before  an  annual  meeting,  including  proposed  nominations  of

persons for election to our board of directors;

● establish that our board of directors is divided into three classes, with each class serving three-year staggered terms;

● require the approval of our board of directors or the holders of at least seventy-five percent (75%) of our outstanding shares of capital stock to

amend our bylaws and certain provisions of our certificate of incorporation;

● limit who may call stockholder meetings;

● do not provide for cumulative voting rights; and

● provide that all vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum.

In addition, Section 203 of the Delaware General Corporation Law may limit our ability to engage in any business combination with a person who
beneficially  owns  15%  or  more  of  our  outstanding  voting  stock  unless  certain  conditions  are  satisfied.  This  restriction  lasts  for  a  period  of  three  years
following  the  share  acquisition.  These  provisions  may  have  the  effect  of  entrenching  our  management  team  and  may  deprive  our  stockholders  of  the
opportunity to sell their shares to potential acquirers at a premium over prevailing prices. This potential inability to obtain a control premium could reduce
the price of our common stock.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for
certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes
with us or our directors, officers or stockholders.

Provisions in our amended and restated certificate of incorporation provide that the Court of Chancery of the State of Delaware will, to the fullest

extent permitted by law, be the sole and exclusive forum for:

● any derivative action or proceeding brought on our behalf;

● any action asserting a claim of breach of a fiduciary duty owed to us or our stockholders by any of our directors, officers or other employees;

● any action asserting a claim against us or any of our directors, officers or other employees arising pursuant to any provision of Delaware law

or our charter documents; or

● any action  asserting  a  claim  against  us  or  any  of  our  directors,  officers  or  other  employees  governed  by  the  internal  affairs  doctrine,  but
excluding actions to enforce a duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive
jurisdiction.

In  addition,  unless  we  consent  in  writing  to  the  selection  of  an  alternative  forum,  the  Federal  district  courts  of  the  United  States  shall  be  the
exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. However, a court may determine that this
provision is unenforceable.

Ownership portions held by our executives and directors, as well as by our former parent company, Harrow Health, Inc., may limit our stockholders’
ability to influence corporate matters.

Our directors and executive officers beneficially own approximately 5.0% of our common stock. Additionally, Harrow Health, Inc. (“Harrow”),
our former parent company, holds approximately 7.8% of our outstanding common stock as of March 7, 2023. Accordingly, these parties, together, can
significantly influence, though not independently determine, the outcome of matters required to be submitted to our stockholders for approval, including
decisions relating to the election of our board of directors and the outcome of any proposed merger or consolidation of our company. These interests may
not be consistent with those of our other stockholders. In addition, the significant interest held by these parties, and particularly by Harrow, may discourage
third parties from seeking to acquire control of us, which may adversely affect the market price of our shares.

As  stockholders  in  our  company,  you  will  be  deemed  to  have  notice  of  and  have  consented  to  the  provisions  of  our  amended  and  restated
certificate of incorporation related to choice of forum, but will not be deemed to have waived our compliance with the federal securities laws and the rules
and regulations thereunder. The choice of forum provisions in our amended and restated certificate of incorporation may limit our stockholders’ ability to
obtain a favorable judicial forum for disputes with us or any of our directors, officers or other employees, which may discourage lawsuits with respect to
such claims. Alternatively, if a court were to find the choice of forum provision contained in our restated charter to be inapplicable or unenforceable in an
action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations and
financial condition.

Results of Operations

To date, we have realized revenues from the sale of our neurology products portfolio to Azurity in 2021, a licensing arrangement on our EM-100
product  that  was  sold  to  Bausch  Health,  the  launch  of  our  Biorphen®,  ALKINDI  SPRINKLE®,  and  Carglumic  Acid  products  in  December  2019,
December  2020,  and  December  2021,  respectively,  and  also  from  the  sale  of  our  hospital  products  portfolio  to  Dr.  Reddy’s  in  2022.  We  anticipate
successfully growing sales of our commercialized products and commercializing additional product candidates in 2023 and beyond.

Year Ended December 31, 2022 Compared to Year Ended December 31, 2021

Net  revenues  of  $21.3  million  in  2022  included  $10.0  million  of  licensing  revenue,  consisting  of  $5.0  million  from  Azurity  on  the  launch  of
Zonisamide  and  $5.0  million  from  the  sale  of  our  hospital  products  to  Dr.  Reddy’s.  Net  revenue  of  $21.8  million  in  2021  included  $19.0  million  of
licensing  revenue,  primarily  consisting  of  $17.0  million  from  Azurity  on  three  neurology  products  sold  to  them  at  the  beginning  of  2021.  Net  product
revenue of $11.3 million in 2022 increased by $8.4 million from $2.8 million in 2021 as a result of growth in ALKINDI SPRINKLE® and Carglumic Acid.

Our 2022 gross profit of $14.3 million was down from $19.0 million in 2021, as a result of lower licensing revenue.

For the years ended December 31, 2022 and 2021, we incurred $4.0 million and $6.2 million of research and development (“R&D”) expenses,
respectively, and $18.6 million and $14.3 million of general and administrative (“G&A”) expenses, respectively. The $2.2 million decrease in R&D was
driven by milestone payments on a number of our products in development in 2021 that did not recur in 2022. The $4.3 million increase in G&A expenses
was primarily due to personnel additions and increased sales & marketing spending to support our growing business. We incurred a net loss of $9.0 million
and $2.0 million for the years ended December 31, 2022 and 2021, respectively.

General and Administrative Expenses

G&A  expenses  consist  primarily  of  employee  compensation  expenses,  selling  and  adverting/promotional  expenses,  legal  and  professional  fees,
business insurance and FDA fees associated with approved products. We anticipate that our G&A expenses will increase to support our business growth –
particularly with respect to sales and marketing for additional personnel and promotional expenses.

Research and Development Expenses

We currently have eight employees that support our overall product development function. The majority of our spend in R&D is to third parties we

contract with to develop and test our products in addition to development partner milestone payments.

Year Ended December 31, 2021 Compared to Year Ended December 31, 2020

Net  revenues  of  $21.8  million  in  2021  included  $19.0  million  of  licensing  revenue,  including  $17.0  million  from  Azurity  on  three  neurology
products sold to them at the beginning of the year. Revenues were nominal in 2020 for Biorphen and reflected the launch of ALKINDI SPRINKLE® late in
mid-December.

Our 2021 gross profit of $19.0 million was up significantly as the prior year negative gross profit level was adversely impacted by Biorphen price
discounts  and  a  reserve  charge  to  cost  of  sales  for  certain  slow-moving  Biorphen  inventory  that  we  did  not  believe  we  would  be  able  to  sell  before  its
expiry date.

For the years ended December 31, 2021 and 2020, we incurred $6.2 million and $14.1 million of research and development (“R&D”) expenses,
respectively, and $14.3 million and $12.6 million of general and administrative (“G&A”) expenses, respectively. The $7.9 million decrease in R&D was
driven by significant milestone payments on a number of our products in development in 2020 that did not recur in 2021. The $1.7 million increase in
G&A expenses was primarily due to personnel additions and increased professional/consulting spending to support our growing business. We incurred a
net loss of $2.0 million and $28.0 million for the years ended December 31, 2021 and 2020, respectively.

General and Administrative Expenses

G&A expenses consisted primarily of employee compensation expenses, selling and adverting/promotional expenses, legal and professional fees,
business insurance and FDA fees. We anticipate that our G&A expenses will increase to support our business growth – particularly with respect to sales
and marketing for additional personnel and promotional expenses.

Research and Development Expenses

We had seven employees that supported our overall product development function. The majority of our spend in R&D was to third parties we

contracted with to develop and test our products in addition to development partner milestone payments. We closed our R&D facility in May 2021.

Liquidity and Capital Resources

As of December 31, 2022, we had total assets of $25.0 million, cash and cash equivalents of $16.3 million and working capital of $13.5 million.
We  believe  that  our  existing  funding  and  revenues  from  our  approved  products  will  be  sufficient  for  at  least  the  next  twelve  months  of  our  operations.
However,  our  projected  estimates  for  our  product  development  spending,  administrative  expenses  and  our  working  capital  requirements  could  be
inaccurate, or we may experience growth more quickly or on a larger scale than we expect, any of which could result in the depletion of capital resources
more rapidly than anticipated and could require us to seek additional financing earlier than we expect to support our operations.

Cash Flows

The following table sets forth a summary of our cash flows for the years ended December 31, 2022, 2021 and 2020 (amounts are in thousands):

Net cash provided by (used in) operating activities

The decrease in cash used in operating activities is primarily a result of increased revenue. Investing activities in 2022 and 2021 consist primarily
of licensing fees for Betaine and Carglumic Acid respectively. Financing activities in 2020 consisted of a follow-on common stock offering in October
2020.

Critical Accounting Policies

Our financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The
preparation  of  our  financial  statements  and  related  disclosures  requires  us  to  make  estimates  and  judgments  that  affect  the  reported  amounts  of  assets,
liabilities, costs and expenses in our financial statements. We base our estimates on historical experience, known trends and events and various other factors
that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ
from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 3 to our financial statements included herein, we believe that the

following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

We account for contracts with our customers in accordance with Accounting Standards Codification (“ASC”) 606 — Revenue from Contracts with
Customers. ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, 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 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.

At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each
contract  and  determines  those  that  are  performance  obligations  and  assesses  whether  each  promised  good  or  service  is  distinct.  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.
Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. We assess
whether these options provide a material right to the customer and, if so, they are considered performance obligations. The exercise of a material right is
accounted for as a contract modification for accounting purposes.

We  recognize  as  revenue  the  amount  of  the  transaction  price  that  is  allocated  to  the  respective  performance  obligation  when  (or  as)  each
performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts
received  prior  to  revenue  recognition  will  be  recorded  as  deferred  revenue.  Amounts  expected  to  be  recognized  as  revenue  within  the  twelve  months
following the balance sheet date will be classified as current portion of deferred revenue in our balance sheets. Amounts not expected to be recognized as
revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion.

Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, we will evaluate whether
the  milestone  conditions  have  been  achieved  and  if  it  is  probable  that  a  significant  revenue  reversal  would  not  occur  before  recognizing  the  associated
revenue. Milestone payments that are not within our control or the licensee’s control, such as regulatory approvals, are generally not considered probable of
being achieved until those approvals are received.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a
customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, we will recognize revenue at the
later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied or
partially satisfied.

Significant Financing Component – In determining the transaction price, we will adjust consideration for the effects of the time value of money if

the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one year.

The  Company  sells  its  ALKINDI  SPRINKLE®  and  Carglumic  Acid  product  to  one  pharmacy  distributor  customer  which  provides  order
fulfilment and inventory storage/distribution services. The Company may sell products in the U.S. to wholesale pharmaceutical distributors, who then sell
the  product  to  hospitals  and  other  end-user  customers.  Sales  to  wholesalers  are  made  pursuant  to  purchase  orders  subject  to  the  terms  of  a  master
agreement, and delivery of individual shipments represent performance obligations under each purchase order. The Company uses a third-party logistics
(“3PL”) vendor to process and fulfill orders and has concluded it is the principal in the sales to wholesalers because it controls access to the 3PL vendor
services rendered and directs the 3PL vendor activities. The Company has no significant obligations to wholesalers to generate pull-through sales.

50

 
 
 
 
 
 
 
 
 
 
For its ALKINDI SPRINKLE® and Carglumic Acid products, the Company bills at the initial product list price which are subject to offsets for
patient  co-pay  assistance  and  potential  state  Medicaid  reimbursements  which  are  recorded  as  a  reduction  of  net  revenues  at  the  date  of  sale/shipment.
Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell products at
negotiated discounted prices to members of certain group purchasing organizations (“GPOs”) and government programs. Because of the shelf life of the
product and the Company’s lengthy return period, there may be a significant period of time between when the product is shipped and when it issues credits
on returned product.

The Company estimates the transaction price when it receives each purchase order taking into account the expected reductions of the selling price
initially billed to the wholesaler/distributor arising from all of the above factors. The Company has developed estimates for future returns and chargebacks
and the impact of other discounts and fees it pays, although ALKINDI SPRINKLE® and Carglumic Acid sales are not subject to returns. When estimating
these adjustments to the transaction price, the Company reduces it sufficiently to be able to assert that it is probable that there will be no significant reversal
of revenue when the ultimate adjustment amounts are known.

The  Company  stores  its  ALKINDI  SPRINKLE®  and  Carglumic  Acid  inventory  at  its  pharmacy  distributor  customer  location,  and  sales  are
recorded  when  stock  is  pulled  and  shipped  to  fulfill  specific  patient  orders.  The  Company  recognizes  revenue  and  cost  of  sales  from  products  sold  to
wholesalers upon delivery to the wholesaler location. At that time, the wholesalers take control of the product as they take title, bear the risk of loss of
ownership and have an enforceable obligation to pay the Company. They also have the ability to direct sales of product to their customers on terms and at
prices  they  negotiate.  Although  wholesalers  have  product  return  rights,  the  Company  does  not  believe  they  have  a  significant  incentive  to  return  the
product.

Upon  recognition  of  revenue  from  product  sales,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,  prompt
payment  discounts,  state  Medicaid  and  GPO  fees  are  included  in  sales  reserves,  accrued  liabilities  and  net  accounts  receivable.  The  Company  monitors
actual product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from its estimates, it will make adjustments
to these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment.

In addition, the Company anticipates it will continue to receive revenues from product licensing agreements where it has contracted for milestone

payments and royalties from products it has developed or acquired.

Stock-Based Compensation

We account for stock-based compensation under the provisions of ASC 718 Compensation – Stock Compensation. The guidance under ASC 718
requires  companies  to  estimate  the  fair  value  of  the  stock-based  compensation  awards  on  the  date  of  grant  and  record  expense  over  the  related  service
periods,  which  are  generally  the  vesting  period  of  the  equity  awards.  Compensation  expense  is  recognized  over  the  period  during  which  services  are
rendered by consultants and non-employees until completed. At the end of each financial reporting period prior to completion of the service, the fair value
of these awards is remeasured using the then-current fair value of our common stock and updated assumption inputs in the Black-Scholes option-pricing
model (“BSM”).

We estimate the fair value of stock-based option awards to our using the BSM. The BSM requires the input of subjective assumptions, including
the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of the underlying common stock on the date of grant,
among  other  inputs.  The  risk-free  interest  rate  was  determined  from  the  implied  yields  for  zero-coupon  U.S.  government  issues  with  a  remaining  term
approximating the expected life of the options or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options.
The expected term of stock options granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable
companies’ historical volatility along with a limited weighting included for our own volatility subsequent to our IPO, which we believe represents the most
accurate basis for estimating expected future volatility under the current conditions. We account for forfeitures as they occur.

51

 
 
 
 
 
 
 
 
 
 
Prior  to  our  initial  public  offering  in  November  2018,  the  fair  value  of  the  shares  of  common  stock  underlying  our  stock-based  awards  was
determined by our board of directors, with input from management. Because there had been no public market for our common stock prior to the IPO, our
board of directors had determined the fair value of the common stock on the grant-date of the stock-based award by considering a number of objective and
subjective  factors,  including  enterprise  valuations  of  our  common  stock  performed  by  an  unrelated  third-party  specialist,  valuations  of  comparable
companies, sales of our convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of our capital stock,
and  general  and  industry-specific  economic  outlook.  Following  our  IPO,  we  use  the  closing  stock  price  on  the  date  of  grant  for  the  fair  value  of  the
common stock.

Research and Development Expenses

R&D expenses include both internal R&D activities and external contracted services. Internal R&D activity expenses include salaries, benefits and
stock-based  compensation  and  other  costs  to  support  our  R&D  operations.  External  contracted  services  include  product  development  efforts  including
certain product licensor milestone payments, clinical trial activities, manufacturing and control-related activities and regulatory costs. R&D expenses are
charged to operations as incurred. We review and accrue R&D expenses based on services performed and rely upon estimates of those costs applicable to
the  stage  of  completion  of  each  project.  Significant  judgments  and  estimates  are  made  in  determining  the  accrued  balances  at  the  end  of  any  reporting
period. Actual results could differ from our estimates.

Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed
as  R&D  in  the  period  in  which  they  are  incurred.  Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  R&D
activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed.

Off Balance Sheet Transactions

We do not have any off-balance sheet transactions.

JOBS Act Transition Period

In April 2012, the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), was enacted. Section 107 of the JOBS Act provides that an
“emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with
new  or  revised  accounting  standards.  Thus,  an  emerging  growth  company  can  delay  the  adoption  of  certain  accounting  standards  until  those  standards
would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will
adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

Subject  to  certain  conditions,  as  an  emerging  growth  company,  we  may  rely  on  certain  of  these  exemptions,  including  without  limitation,  (i)
providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act
and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board (“PCAOB”) regarding mandatory audit
firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor
discussion and analysis. We will remain an emerging growth company until the earlier to occur of (1) the last day of the fiscal year (a) December 31, 2023,
which is the end of the fiscal year following the fifth anniversary of the completion of our IPO, (b) in which we have total annual gross revenues of at least
$1.07 billion or (c) in which we are deemed to be a “large accelerated filer” under the rules of the SEC, which means the market value of our common
stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-
convertible debt during the prior three-year period.

52

 
 
 
 
 
 
 
 
 
 
 
Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The  primary  objective  of  our  investment  activities  is  to  preserve  capital.  We  do  not  utilize  hedging  contracts  or  similar  instruments.  We  are
exposed to certain market risks relating primarily to interest rate risk on our cash and cash equivalents and risks relating to the financial viability of the
institutions which hold our capital and through which we have invested our funds. We manage such risks by investing in short-term, liquid, highly rated
instruments. As of December 31, 2022, our cash equivalents only included cash deposits at our bank. From time to time, we do have cash investments in
short-term money market or U.S. treasury bills. We do not believe we have any material exposure to interest rate risk due to the extremely low interest rate
environment and the short duration of the invested funds we hold. Declines in interest rates would reduce our investment income but would not have a
material effect on our financial condition or results of operations. We do not currently have exposure to foreign currency risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Eton Pharmaceuticals, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Eton  Pharmaceuticals,  Inc.  (the  “Company”)  as  of  December  31,  2022  and  2021,  the  related
statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2022, and the related notes
(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position
of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2022, 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 these 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 a separate opinion on the
critical audit matter or on the accounts or disclosures to which it relates.

Product Sales Deductions

Critical Audit Matter Description

As described in Note 3 to the financial statements under the caption “Revenue Recognition for Contracts with Customers,” revenues from product sales are
recognized net of reductions for estimated returns, chargebacks, distribution fees, prompt payment discounts, state Medicaid and GPO fees (collectively,
“sales deductions”), which are established at the time of sale.

Auditing the estimation of sales deductions was challenging because of the limited sales history of the Company’s products and the subjectivity of certain
assumptions  required  to  estimate  those  amounts.  In  particular,  management  estimates  potential  chargebacks,  which  relate  to  price  reductions  below  the
estimated sales price that the wholesalers provide to certain customers, based on historical industry data for competitive products and adjusted for actual
historical  experience.  In  addition,  management  estimates  its  provision  for  product  returns  based  on  prior  experience  with  similar  product  launches  and
considers other factors such as levels of inventory in the distribution channel, forecasted buying patterns, and product dating and expiration period. The
product  sales  deductions  are  estimated  based  on  current  contractual  and  statutory  requirements,  market  events  and  trends,  and  internal  and  external
historical data.

How the Critical Audit Matter Was Addressed in the Audit

To test management’s estimated product sales deductions, we obtained management’s calculations for the respective estimates and performed the following
procedures, among others. We tested management’s estimation process for determining of product sales discounts accruals by developing an independent
expectation of the estimated accrual rate, including a comparison of rates used in management’s forecast to rates in the underlying contracts and performing
a retrospective review of assumptions to actual activity. In addition, we assessed subsequent events to determine whether there was any new information
that would require adjustment to the initial accruals, evaluated trends in actual sales and discount accrual balances, and compared cash receipts to product
sales. We also examined terms and conditions for a sample of contracts with the Company’s customers, tested a sample of credits issued and payments
made throughout the year and agreed rates to underlying contract terms.

To  date,  the  Company  has  generated  revenues  from  multiple  products  and  expects  further  growth  in  2023  and  beyond  in  accordance  with
additional  market  penetration  from  these  products  plus  revenues  from  additional  products  where  it  anticipates  FDA  approval.  The  Company  currently
believes its existing cash and cash equivalents of $16,305 as of December 31, 2022 will be sufficient to fund its operating expenses and capital expenditure
requirements for at least the next twelve months from the date of issuance of these financial statements. This estimate is based on the Company’s current
assumptions, including assumptions relating to estimated sales and its ability to manage its spending. The Company could use its available capital resources
sooner than currently expected. Accordingly, the Company could seek to obtain additional capital through equity financings, the issuance of debt or other
arrangements. However, there can be no assurance that the Company will be able to raise additional capital if needed or under acceptable terms, if at all.
The sale of additional equity may dilute existing stockholders and newly issued shares may contain senior rights and preferences compared to currently
outstanding common shares. The Company’s existing long-term debt obligation contains covenants and limits the Company’s ability to pay dividends or
make other distributions to stockholders. If the Company experiences delays in product sales growth and completing its product development and obtaining
regulatory  approval  for  its  other  product  candidates  and  is  unable  to  obtain  such  additional  financing,  operations  would  need  to  be  scaled  back  or
discontinued.

Note 3 — Summary of Significant Accounting Policies (continued)

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported
amounts  of  assets  and  liabilities,  the  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of
revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these financial statements include, but are not limited
to, provisions for uncollectible receivables, chargebacks and sales returns, valuation of inventories, useful lives of assets and the impairment of property
and equipment, deferred tax assets, the accrual of research and development expenses and the valuation of common stock, stock options and warrants, and
restricted stock units (“RSUs”). Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are
recorded in the period in which they become known. Actual results could differ from those estimates or assumptions.

Segment Information

The  Company  operates  the  business  on  the  basis  of  a  single  reportable  segment,  which  is  the  business  of  developing  and  commercializing
prescription drug products. The Company’s chief operating decision-maker is the Chief Executive Officer (“CEO”), who evaluates the Company as a single
operating segment.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash
equivalents  are  held  in  U.S.  financial  institutions  or  invested  in  short-term  U.S.  treasury  bills  or  high-grade  money  market  funds.  From  time  to  time,
amounts deposited with its bank exceed federally insured limits. The Company believes the associated credit risk to be minimal.

Accounts Receivable

Accounts  receivable  are  recorded  at  the  invoiced  amount  and  are  non-interest  bearing.  Accounts  receivable  are  recorded  net  of  allowances  for
doubtful accounts, cash discounts for prompt payment, distribution fees, chargebacks and returns and allowances. The total for these reserves amounted to
$262 and $96 as of December 31, 2022 and 2021, respectively.

Inventories

The  Company  values  its  inventories  at  the  lower  of  cost  or  net  realizable  value  using  the  first-in,  first-out  method  of  valuation.  The  Company
reviews its inventories for potential excess or obsolete issues on an ongoing basis and will record a write-down if an impairment is identified. Inventories at
December  31,  2022  and  2021  consist  solely  of  purchased  finished  goods.  At  December  31,  2022,  inventories  are  shown  net  of  a  reserve  for  damaged
Biorphen  inventory  yet  to  be  destroyed  and  net  of  ALKINDI  SPRINKLE®  inventory  at  risk  of  expiry  prior  to  being  sold.  At  December  31,  2021,
inventories  are  shown  net  of  a  reserve  for  Biorphen  inventory  due  to  the  risk  of  expiry  prior  to  being  sold.  There  was  an  inventory  reserve  of  $62  and
$1,414 at December 31, 2022 and 2021, respectively.

Property and Equipment

Property  and  equipment  are  stated  at  cost.  Depreciation  of  property  and  equipment  is  computed  utilizing  the  straight-line  method  based  on  the
following estimated useful lives. Computer hardware and software is depreciated over three years. Equipment, furniture and fixtures is depreciated over
five years.  Leasehold  improvements  are  amortized  over  their  estimated  useful  lives  or  the  remaining  lease  term,  whichever  is  shorter.  Construction  in
progress is capitalized but not depreciated until it is placed into service.

Maintenance and repairs are charged to expense as incurred, while renewals and improvements are capitalized.

Intangible Assets

The Company capitalizes payments it makes for licensed products when the payment is based on FDA approval for the product and the cost is
recoverable based on expected future cash flows from the product. The cost is amortized on a straight-line basis over the estimated useful life of the product
commencing on the approval date in accordance with Accounting Standards Codification (“ASC”) 350 — Intangibles - Goodwill and Other. In November
2021, the Company purchased the rights for its Carglumic Acid product for $3,250 and that cost is being amortized over ten years. A $750 payment related
to the approval of Biorphen had been capitalized in 2019 and that cost was being amortized over five years. As a result of the Biorphen sale to Dr. Reddy’s
(see Note 14), amortization of that asset was accelerated to record $275 of expense in June 2022 and the remaining $75 of expense in the last six months of
the  year  ended  December  31,  2022.  A  $750  payment  related  to  the  approval  of  Rezipres®  had  been  capitalized  in  Q1  2022  and  that  cost  was  being
amortized over five years. As a result of the sale to Dr. Reddy’s, amortization of the Rezipres® asset was accelerated to record the remaining $738 in the
three-month period ended June 30, 2022. In September 2022, the Company purchased the rights for its Betaine Anhydrous product for $2,000 and that cost
is being amortized over five years. The intangible assets, net on the Company’s balance sheet reflected $1,996 of accumulated amortization as of December
31, 2022. The Company recorded $1,617, $204, and $150 of amortization expense for the years ended December 31, 2022, 2021, and 2020 respectively.
During the years ended December 31, 2021 and 2020, the Company reclassified $204 and $150 of amortization expense of intangible assets, respectively,
to cost of sales to conform with the current year presentation. The table below shows the estimated remaining amortization for these products for each of
the five years from 2023 to 2027 and thereafter.

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted
future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is
recognized in the Company’s statements of operations for the amount by which the carrying amount of the asset exceeds the fair value of the asset. No
impairment was recognized during the years ended December 31, 2022, 2021 and 2020.

Debt Issuance Costs and Debt Discount and Detachable Debt-Related Warrants

Costs  incurred  to  issue  debt  are  deferred  and  recorded  as  a  reduction  to  the  debt  balance  in  the  accompanying  balance  sheets.  The  Company
amortizes debt issuance costs over the expected term of the related debt using the effective interest method. Debt discounts relate to the relative fair value
of warrants issued in conjunction with the debt and are also recorded as a reduction to the debt balance and accreted over the expected term of the debt to
interest expense using the effective interest method.

Note 3 — Summary of Significant Accounting Policies (continued)

Leases

The Company accounts for leases in accordance with ASC Topic 842 — Leases. The Company reviews all relevant facts and circumstances of a
contract to determine if it is a lease whereby the terms of the agreement convey the right to control the direct use and receive substantially all the economic
benefits of an identified asset for a period of time in exchange for consideration. The associated right-of-use assets and lease liabilities are recognized at
lease commencement. The Company measures lease liabilities based on the present value of the lease payments over the lease term discounted using the
rate it would pay on a loan with the equivalent payments and term for the lease. The Company does not include the impact for lease term options that
would extend or terminate the lease unless it is reasonably certain that it will exercise any such options. The Company accounts for the lease components
separately from non-lease components for its operating leases.

The Company measures right-of-use assets based on the corresponding lease liabilities adjusted for (i) any prepayments made to the lessor at or
before  the  commencement  date,  (ii)  initial  direct  costs  it  incurs,  and  (iii)  any  incentives  under  the  lease.  In  addition,  the  Company  evaluates  the
recoverability of its right-of-use assets for possible impairment in accordance with its long-lived assets policy.

Operating leases are reflected on the balance sheets as operating lease right-of-use assets, current accrued liabilities and long-term operating lease

liabilities. The Company does not have any finance leases as of December 31, 2022 and 2021.

The Company commences recognizing operating lease expense when the lessor makes the underlying asset available for use by the Company and

the operating lease expense is recognized on a straight-line basis over the term of the lease. Variable lease payments are expensed as incurred.

The  Company  does  not  recognize  right-of-use  assets  or  lease  liabilities  for  leases  with  a  term  of  twelve  months  or  less;  such  lease  costs  are

recorded in the statements of operations on a straight-line basis over the lease term.

Patent Costs

All  patent-related  costs  incurred  in  connection  with  filing  and  prosecuting  patent  applications  are  expensed  as  incurred  due  to  the  uncertainty

about the successful award of a patent and the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses.

Concentrations of Credit Risk, Sources of Supply and Significant Customers

The Company is subject to credit risk for its cash and cash equivalents which are invested in money market funds and U.S. treasury bills from time
to time. The Company maintains its cash and cash equivalent balances with one major commercial bank and the deposits held with the financial institution
exceed the amount of insurance provided on such deposits and is exposed to credit risk in the event of a default by the financial institutions holding its cash
and cash equivalents to the extent recorded on the balance sheets. The Company believes the associated credit risk to be minimal.

The  Company  is  dependent  on  third-party  suppliers  for  its  products  and  product  candidates.  In  particular,  the  Company  relies,  and  expects  to
continue  to  rely,  on  a  small  number  of  suppliers  to  manufacture  key  chemicals,  approved  products  and  process  its  product  candidates  as  part  of  its
development programs. These programs could be adversely affected by a significant interruption in the manufacturing process.

Note 3 — Summary of Significant Accounting Policies (continued)

The Company is also subject to credit risk from its accounts receivable related to product sales as it extends credit based on an evaluation of the
customer’s  financial  condition,  and  collateral  is  not  required.  Management  monitors  its  exposure  to  accounts  receivable  by  periodically  evaluating  the
collectability of the account receivable based on a variety of factors including the length of time the receivables are past due, the financial health of the
customer and historical experience. Based upon the review of these factors, the Company recorded no allowance for doubtful accounts at December 31,
2022 or 2021. The accounts receivable balance at December 31, 2022 and 2021 and product sales revenue recognized during the year ended December 31,
2022 and 2021 consist of sales to and amounts due from AmerisourceBergen Corporation, Cardinal Health Services and McKesson Corporation for sales of
the Company’s Biorphen product. The December 31, 2022 accounts receivable balance and sales in 2022 also include amounts due from AnovoRx for sales
of the Company’s ALKINDI SPRINKLE® product and its Carglumic Acid product. AnovoRx sales made up 45.5% of 2022 total net revenues and 79.8%
of net accounts receivable as of December 31, 2022, and 9.0% of 2021 total net revenues and 6.4% of net accounts receivable as of December 31, 2021.

Revenue Recognition for Contracts with Customers

The  Company  accounts  for  contracts  with  its  customers  in  accordance  with  ASC  606  —  Revenue  from  Contracts  with  Customers.  ASC  606
applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, 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 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.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised
within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company
then  recognizes  as  revenue  the  amount  of  the  transaction  price  that  is  allocated  to  the  respective  performance  obligation  when  (or  as)  the  performance
obligation  is  satisfied.  Arrangements  that  include  rights  to  additional  goods  or  services  that  are  exercisable  at  a  customer’s  discretion  are  generally
considered  options.  The  Company  assesses  whether  these  options  provide  a  material  right  to  the  customer  and,  if  so,  they  are  considered  performance
obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes.

The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as)
each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method. Any amounts
received  prior  to  revenue  recognition  will  be  recorded  as  deferred  revenue.  Amounts  expected  to  be  recognized  as  revenue  within  the  twelve  months
following the balance sheet date will be classified as current portion of deferred revenue in the Company’s balance sheets. Amounts not expected to be
recognized as revenue within the twelve months following the balance sheet date are classified as long-term deferred revenue, net of current portion.

Milestone Payments – If a commercial contract arrangement includes development and regulatory milestone payments, the Company will evaluate
whether  the  milestone  conditions  have  been  achieved  and  if  it  is  probable  that  a  significant  revenue  reversal  would  not  occur  before  recognizing  the
associated revenue. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are generally not
considered probable of being achieved until those approvals are received.

Note 3 — Summary of Significant Accounting Policies (continued)

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a
customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, the Company will recognize
revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has
been satisfied or partially satisfied.

Significant Financing Component – In determining the transaction price, the Company will adjust consideration for the effects of the time value of
money if the expected period between payment by the licensees and the transfer of the promised goods or services to the licensees will be more than one
year.

The  Company  sells  its  ALKINDI  SPRINKLE®  and  Carglumic  Acid  product  to  one  pharmacy  distributor  customer  which  provides  order
fulfilment and inventory storage/distribution services. The Company may sell products in the U.S. to wholesale pharmaceutical distributors, who then sell
the  product  to  hospitals  and  other  end-user  customers.  Sales  to  wholesalers  are  made  pursuant  to  purchase  orders  subject  to  the  terms  of  a  master
agreement, and delivery of individual shipments represent performance obligations under each purchase order. The Company uses a third-party logistics
(“3PL”) vendor to process and fulfill orders and has concluded it is the principal in the sales to wholesalers because it controls access to the 3PL vendor
services rendered and directs the 3PL vendor activities. The Company has no significant obligations to wholesalers to generate pull-through sales.

For its ALKINDI SPRINKLE® and Carglumic Acid products, the Company bills at the initial product list price which are subject to offsets for
patient  co-pay  assistance  and  potential  state  Medicaid  reimbursements  which  are  recorded  as  a  reduction  of  net  revenues  at  the  date  of  sale/shipment.
Selling prices initially billed to wholesalers are subject to discounts for prompt payment and subsequent chargebacks when the wholesalers sell products at
negotiated discounted prices to members of certain group purchasing organizations (“GPOs”) and government programs. Because of the shelf life of the
product and the Company’s lengthy return period, there may be a significant period of time between when the product is shipped and when it issues credits
on returned product.

The Company estimates the transaction price when it receives each purchase order taking into account the expected reductions of the selling price
initially billed to the wholesaler/distributor arising from all of the above factors. The Company has developed estimates for future returns and chargebacks
and the impact of other discounts and fees it pays, although ALKINDI SPRINKLE® and Carglumic Acid sales are not subject to returns. When estimating
these adjustments to the transaction price, the Company reduces it sufficiently to be able to assert that it is probable that there will be no significant reversal
of revenue when the ultimate adjustment amounts are known.

The  Company  stores  its  ALKINDI  SPRINKLE®  and  Carglumic  Acid  inventory  at  its  pharmacy  distributor  customer  location,  and  sales  are
recorded  when  stock  is  pulled  and  shipped  to  fulfill  specific  patient  orders.  The  Company  recognizes  revenue  and  cost  of  sales  from  products  sold  to
wholesalers upon delivery to the wholesaler location. At that time, the wholesalers take control of the product as they take title, bear the risk of loss of
ownership and have an enforceable obligation to pay the Company. They also have the ability to direct sales of product to their customers on terms and at
prices  they  negotiate.  Although  wholesalers  have  product  return  rights,  the  Company  does  not  believe  they  have  a  significant  incentive  to  return  the
product.

Upon  recognition  of  revenue  from  product  sales,  the  estimated  amounts  of  credit  for  product  returns,  chargebacks,  distribution  fees,  prompt
payment  discounts,  state  Medicaid  and  GPO  fees  are  included  in  sales  reserves,  accrued  liabilities  and  net  accounts  receivable.  The  Company  monitors
actual product returns, chargebacks, discounts and fees subsequent to the sale. If these amounts end up differing from its estimates, it will make adjustments
to these allowances, which are applied to increase or reduce product sales revenue and earnings in the period of adjustment.

In addition, the Company anticipates it will receive revenues from product licensing agreements where it has contracted for milestone payments

and royalties from products it has developed or acquired.

Note 3 — Summary of Significant Accounting Policies (continued)

Cost of Product Sales

Cost of product sales consists of the profit-sharing and royalty fees with the Company’s product licensing and development partners, the purchase
costs for finished products from third-party manufacturers, the amortization of certain intangible assets, and freight and handling/storage costs from the
Company’s  3PL  logistics  service  providers.  The  cost  of  sales  for  profit-sharing  and  royalty  fees  and  costs  for  purchased  finished  products  and  the
associated  inbound  freight  expense  is  recorded  when  the  associated  product  sale  revenue  is  recognized  in  accordance  with  the  terms  of  shipment  to
customers  while  outbound  freight  and  handling/storage  fees  charged  by  the  3PL  service  provider  are  expensed  as  they  are  incurred.  Cost  of  sales  also
reflects any write-downs or reserve adjustments for the Company’s inventories.

Research and Development Expenses

Research  and  development  (“R&D”)  expenses  include  both  internal  R&D  activities  and  external  contracted  services.  Internal  R&D  activity
expenses include salaries, benefits and stock-based compensation and other costs to support the Company’s R&D operations. External contracted services
include  product  development  efforts  such  as  certain  product  licensor  milestone  payments,  clinical  trial  activities,  manufacturing  and  control-related
activities and regulatory costs. R&D expenses are charged to operations as incurred. The Company reviews and accrues R&D expenses based on services
performed and relies upon estimates of those costs applicable to the stage of completion of each project. Significant judgments and estimates are made in
determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates.

Upfront payments and milestone payments made for the licensing of technology for products that are not yet approved by the FDA are expensed
as  R&D  in  the  period  in  which  they  are  incurred.  Nonrefundable  advance  payments  for  goods  or  services  to  be  received  in  the  future  for  use  in  R&D
activities are recorded as prepaid expenses and are expensed as the related goods are delivered or the services are performed.

Income (Loss) Per Share

Basic net income (loss) per common share is computed by dividing net income (loss) attributable to common stockholders for the period by the
weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income
(loss) attributable to common stockholders for the period by the weighted average number of common and common equivalent shares, such as Series A
Preferred, unvested restricted stock, stock options and warrants that are outstanding during the period. Common stock equivalents are excluded from the
computation when their inclusion would be anti-dilutive. No such adjustments were made for 2022, 2021 or 2020 as the Company reported a net loss for
the years ended December 31, 2022, 2021 and 2020 and including the effects of common stock equivalents in the diluted earnings per share calculation
would have been anti-dilutive (see Note 9).

Stock-Based Compensation

The  Company  accounts  for  stock-based  compensation  under  the  provisions  of  ASC  718  Compensation  —  Stock  Compensation.  The  guidance
under ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant and record expense over the
related service periods, which are generally the vesting period of the equity awards. The Company estimates the fair value of stock-based option awards
using the Black-Scholes-Merton option-pricing model (“BSM”). The BSM requires the input of subjective assumptions, including the expected stock price
volatility, the calculation of expected term, forfeitures and the fair value of the underlying common stock on the date of grant, among other inputs. The risk-
free interest rate was determined from the implied yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of
the  options  or  warrants.  Dividends  on  common  stock  are  assumed  to  be  zero  for  the  BSM  valuation  of  the  stock  options.  The  expected  term  of  stock
options  granted  is  based  on  vesting  periods  and  the  contractual  life  of  the  options.  Expected  volatilities  are  based  on  comparable  companies’  historical
volatility  along  with  a  limited  weighting  included  for  the  Company’s  own  volatility,  which  management  believes  represents  the  most  accurate  basis  for
estimating  expected  future  volatility  under  the  current  conditions.  The  Company  accounts  for  forfeitures  as  they  occur.  The  Company  uses  the  closing
common stock price on the date of grant for the fair value of the common stock.

Income Taxes

As part of the process of preparing the Company’s financial statements, the Company must estimate the actual current tax liabilities and assess
temporary  differences  resulting  from  differing  treatment  of  items  for  tax  and  accounting  purposes.  These  differences  result  in  deferred  tax  assets  and
liabilities, which are included within the balance sheets. The Company must assess the likelihood that the deferred tax assets will be recovered from future
taxable income and, to the extent the Company believes that recovery is not likely, a valuation allowance must be established. To the extent the Company
establishes a valuation allowance or increase or decrease to this allowance in a period, the impact will be included in income tax expense in the statements
of operations. As of December 31, 2022 and 2021, the Company has established a 100% valuation reserve against its deferred tax assets.

The Company accounts for income taxes under the provisions of ASC 740 - Income Taxes. As of December 31, 2022 and 2021, there were no
unrecognized tax benefits included in the balance sheets that would, if recognized, affect the effective tax rate. The Company’s practice is to recognize
interest and penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties in its balance sheets at
December 31, 2022 or 2021, and has not recognized interest and penalties in the statements of operations for the years ended December 31, 2022, 2021 and
2020. As of December 31, 2022, the Company is subject to taxation in the United States and certain individual states – primarily Illinois and Tennessee.
The Company’s tax losses from 2017 through 2022 are subject to examination by the federal and state tax authorities due to the carryforward of unutilized
net operating losses (“NOLs”).

Current  accounting  standards  include  guidance  on  the  accounting  for  uncertainty  in  income  taxes  recognized  in  the  financial  statements.  Such
standards also prescribe a recognition threshold and measurement model for the financial statement recognition of a tax position taken, or expected to be
taken, and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company
believes that the ultimate deductibility of all tax positions is highly certain, although there is uncertainty about the timing of such deductibility. As a result,
no liability for uncertain tax positions was recorded as of December 31, 2022 or 2021.

Fair Value Measurements

We  measure  certain  of  our  assets  and  liabilities  at  fair  value.  Fair  value  represents  the  price  that  would  be  received  to  sell  an  asset  or  paid  to
transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the  measurement  date.  Fair  value  accounting  requires  characterization  of  the
inputs used to measure fair value into a three-level fair value hierarchy as follows:

Level 1 — Inputs based on quoted prices in active markets for identical assets or liabilities. An active market is a market in which transactions

occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 — Observable inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market

data obtained from sources independent from the entity.

Level 3 — Unobservable inputs that reflect the entity’s own assumptions about the assumptions market participants would use in pricing the asset

or liability developed based on the best information available.

significance  of  a  particular  input  to  the  fair  value  measurement  requires  judgment,  which  may  affect  the  valuation  of  the  assets  and  liabilities  and  their
placement  within  the  fair  value  hierarchy  levels.  The  determination  of  the  fair  values  stated  below  takes  into  account  the  market  for  the  Company’s
financials,  assets  and  liabilities,  the  associated  credit  risk  and  other  factors  as  required.  The  Company  considers  active  markets  as  those  in  which
transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

The Company’s financial instruments included cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and long-term
debt  obligation.  The  carrying  amounts  of  these  financial  instruments,  except  for  the  long-term  debt  obligation,  approximate  their  fair  values  due  to  the
short-term  maturities  of  these  instruments.  Based  on  borrowing  rates  currently  available  to  the  Company,  the  carrying  value  of  the  long-term  debt
obligation approximate their respective fair values.

Impact of New Accounting Pronouncements

There  were  no  new  accounting  pronouncements  issued  by  the  Financial  Accounting  Standards  Board  (“FASB”)  during  the  current  period  that

would apply to the Company and have a material impact on its financial position or results of operations.

Note 5 – Debt

SWK Loan

On November 13, 2019, the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Holdings Corporation (“SWK”)
which provided for up to $10,000 in financing. The Company received proceeds of $5,000 at closing and was able to borrow an additional $5,000 upon the
FDA  approval  of  a  second  product  developed  by  the  Company,  excluding  EM-100.  In  March  2020,  in  conjunction  with  the  Company’s  ALKINDI
SPRINKLE® product licensing agreement (see Note 14) and the Company’s March 2020 sale of shares of its common stock (see Note 6), the Company
and SWK amended the SWK Credit Agreement. The amendment provided the Company with the option to immediately draw $2,000 and the ability to
borrow an additional $3,000  based  upon  the  FDA  approval  of  EM-100  and  ALKINDI  SPRINKLE®  which  subsequently  occurred  in  September  2020.
Accordingly, the Company borrowed an additional $2,000 on August 11, 2020. The term of the SWK Credit Agreement is for five years and borrowings
bear interest at a rate of LIBOR 3-month plus 10.0%, subject to a stated LIBOR floor rate of 2.0%. A 2.0% unused credit limit fee is assessed during the
first  twelve  months  after  the  date  of  the  SWK  Credit  Agreement  and  loan  fees  include  a  5.0%  exit  fee  based  on  the  principal  amounts  drawn  which  is
payable at the end of the term of the SWK Credit Agreement. The Company was required to maintain a minimum cash balance of $3,000, only pay interest
on the debt until February 2022 and then pay 5.5% of the loan principal balance commencing on February 15, 2022 and then every three months thereafter
until  November  13,  2024  at  which  time  the  remaining  principal  balance  is  due.  Borrowings  under  the  SWK  Credit  Agreement  are  secured  by  the
Company’s assets. The SWK Credit Agreement contains customary default provisions and covenants which include limits on additional indebtedness. In
March 2020, SWK provided a waiver for the Company to obtain loans with the Small Business Association. In February 2021, the Company notified SWK
that it will not require additional borrowing capacity under the SWK Credit Agreement and terminated the additional borrowing capacity with SWK.

In  connection  with  the  initial  $5,000  borrowed  in  November  2019,  the  Company  issued  warrants  to  SWK  to  purchase  51,239  shares  of  the
Company’s common stock with an exercise price of $5.86 per share. The relative fair value of these 51,239 warrants was $226 and was estimated using the
Black-Scholes-Merton option pricing model with the following assumptions: fair value of the Company’s common stock at issuance of $5.75  per  share;
seven-year contractual term; 95% volatility; 0% dividend rate; and a risk-free interest rate of 1.8%.

In connection with the additional $2,000 borrowed in August 2020, the Company issued warrants for 18,141 shares of its common stock at an
exercise price of $6.62 per share. The relative fair value of the 18,141 warrants was $94 and was estimated using the Black-Scholes-Merton option pricing
model  with  the  following  assumptions:  fair  value  of  the  Company’s  common  stock  at  issuance  of  $6.85  per  share;  seven-year  contractual  term;  95%
volatility; 0% dividend rate; and a risk-free interest rate of 0.4%.

These warrants (the “SWK Warrants”) are exercisable immediately and have a term of seven years from the date of issuance. The SWK Warrants
are subject to a cashless exercise feature, with the exercise price and number of shares issuable upon exercise subject to change in connection with stock
splits, dividends, reclassifications and other conditions.

On April 5, 2022, the Company and SWK entered into an amendment to the SWK Credit Agreement which allowed for a deferral of loan principal
payments until May 2023 and reduced the interest rate to LIBOR 3-month plus 8.0%, subject to a stated LIBOR floor rate of 2.0%. In accordance with the
change, the Company has classified $1,033 as principal due in the next 12 months and the remainder classified as long-term debt in its balance sheet at
December 31, 2022. Because LIBOR was intended to be phased out by the end of 2021, future borrowings under our Credit Agreement could be subject to
reference  rates  other  than  LIBOR.  However,  the  cessation  date  of  LIBOR  has  been  deferred  to  June  30,  2023  and  we  do  not  expect  the  planned
discontinuation of LIBOR to have a material impact on interest payments incurred under the SWK Credit Agreement. The Company is in discussions with
SWK regarding an alternate reference rate.

The Company recorded interest expense of $955, $1,042 and $884 in 2022, 2021 and 2020, respectively, which included $127, $148 and $121,
respectively, of debt discount amortization. The Company had accrued interest of $231 and $134 as of December 31, 2022 and 2021, respectively, which is
included in accrued liabilities in the accompanying balance sheets.

On  July  21,  2020,  the  Company  received  $150  in  loan  proceeds  under  the  Economic  Injury  Disaster  Loan  program  (“EIDL”)  from  the  SBA.  The

Company paid off the full EIDL loan principal and its cumulative interest of $6 in July 2021.

Note 6 — Common Stock

The Company has 50,000,000 authorized shares of $0.001 par value common stock as per its Amended and Restated Certificate of Incorporation.

In March and April 2020, the Company entered into securities purchase agreements with various investors and sold an aggregate of 2,600,000

shares of its common stock at a price of $3.00 per share and received $7,756 in net proceeds after deducting issuance costs associated with the sale.

In March 2020, the Company issued 379,474 shares of its common stock to Diurnal Limited (“Diurnal”) as a milestone fee for acquiring the U.S.
marketing rights to ALKINDI SPRINKLE®, an orphan drug product currently under review with the FDA (see Note 14). The shares were valued at $1,264
based  on  the  Company’s  closing  stock  price  on  the  date  of  issuance  and  this  amount  was  recorded  as  a  component  of  the  Company’s  research  and
development expense and a corresponding increase to its additional paid-in-capital.

In  October  2020,  the  Company  issued  3,220,000  shares  of  its  common  stock  in  a  public  offering  at  an  offering  price  of  $7.00  per  share  and

Note 8 — Share-Based Payment Awards (continued)

Shares that are expired, terminated, surrendered or canceled without having been fully exercised will be available for future awards under the 2018
Plan. In addition, the 2018 Plan provides that commencing January 1, 2019 and through January 1, 2028, the share reserve will be increased by 4% of the
total  number  of  shares  outstanding  as  of  the  preceding  December  31,  subject  to  a  reduction  at  the  discretion  of  the  Company’s  board  of  directors.  On
January 1, 2019, the share reserve was increased by 704,317 shares based on the 17,607,928 shares of common stock outstanding at December 31, 2018.
On January 1, 2020, the share reserve was increased by 715,099  shares  based  on  the  17,877,486  shares  of  common  stock  outstanding  at  December  31,
2019. On January 1, 2021, the share reserve was increased by 972,512 shares based on the 24,312,808 shares of common stock outstanding at December
31,  2020.  On  January  1,  2022,  the  share  reserve  was  increased  by  985,040  shares  based  on  the  24,626,004  shares  of  common  stock  outstanding  at
December 31, 2021. The exercise price for stock options granted is not less than the fair value of common stock as determined by the board of directors as
of the date of grant. The Company uses the closing stock price on the date of grant as the exercise price.

In April 2020, the Company issued 15,190 shares of its common stock as an RSA to a new employee. This RSA vested 25% every three months

and was 100% vested in April 2021.

To date, all stock options issued have been non-qualified stock options, and the exercise prices were set at the fair value for the shares at the dates
of  grant.  Options  typically  have  a  ten-year  life,  except  for  options  to  purchase  50,000  shares  of  the  Company’s  common  stock  granted  to  product
consultants in July 2017 that expired, unexercised, in July 2022 as the Company was not able to file certain product submissions to the FDA prior to the
five-year expiration date. Furthermore, these option awards to the Company’s product consultants would not vest unless certain product submissions are
made to the FDA, and accordingly, the Company has not recorded any expense for these contingently vesting option awards to its product consultants.

In  July  2022  and  September  2022,  the  Company’s  board  of  directors  approved  modifications  of  certain  outstanding  awards  of  two  senior
executives, one of whom retired in May 2022 and the other whose employment was terminated in July 2022. The combined awards had an exercise price
range of $1.37 to $8.61 which were set to expire 90 days after retirement or termination as the case may be, and the Company extended the expiration dates
to  April  2023.  No  other  terms  were  modified.  Due  to  these  modifications,  the  Company  incurred  a  modification  expense  of  approximately  $104 that is
included in general and administration expense on the Statement of Operations for the year ended December 31, 2022.

For the years ended December 31, 2022, 2021, and 2020, the Company’s total stock-based compensation expense was $4,218, $3,381 and $2,576,
respectively. Of these amounts, $3,954, $2,838 and $2,295 was recorded in general and administrative expenses, respectively, and $264, $543  and  $281
was recorded in R&D expenses, respectively.

Expected Term — The Company has opted to use the “simplified method” for estimating the expected term of options granted to employees and
directors, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option (generally 10 years).
The expected term of options granted to non-employees equals the contractual life of the options.

Expected Volatility — Due to the Company’s limited operating history and a lack of Company-specific historical and implied volatility data, the
Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The historical
volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term
of the stock-based awards. The Company has also applied some limited weighting to its own volatility.

Risk-Free Interest Rate — The risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of

the Company’s stock options.

Expected Dividend — The Company has not issued any dividends in its history and does not expect to issue dividends over the life of the options

and therefore has estimated the dividend yield to be zero.

Fair value of Common Stock —The Company uses the closing stock price on the date of grant for the fair value of the common stock.

As of December 31, 2022, there was a total of $3,868 of unrecognized compensation costs related to non-vested stock option awards which will be

recognized over a weighted average period of 2 years.

Note 8 — Share-Based Payment Awards (continued)

Employee Stock Purchase Plan

In December 2018, the Company’s board of directors adopted an initial offering of the Company’s common stock under the Company’s ESPP. The
Company’s ESPP provides for an initial reserve of 150,000 shares and this reserve is automatically increased on January 1 of each year by the lesser of 1%
of the outstanding common shares at December 31 of the preceding year or 150,000 shares, subject to reduction at the discretion of the Company’s board of
directors.

The terms of the ESPP permit employees of the Company to use payroll deductions to purchase stock at a price per share that is at least the lesser
of (1) 85% of the fair market value of a share of common stock on the first date of an offering or (2) 85% of the fair market value of a share of common
stock on the date of purchase. After the initial offering period, subsequent twelve-month offering periods automatically commence over the term of the
ESPP on the day that immediately follows the conclusion of the preceding offering, each consisting of two purchase periods approximately six months in
duration ending on or around June 10 and December 10 each year, subject to a restart feature if the Company’s stock price drops at the end of a six-month
period within the twelve-month offering period.

The  Company  recorded  an  expense  of  $128,  $73  and  $71  in  2022,  2021,  and  2020,  respectively,  related  to  the  ESPP.  For  the  years  ended
December 31, 2022 and 2021, there were 69,884 and 49,155 share issuances, respectively, under the ESPP. The weighted average grant date fair value of
share awards in 2022, 2021, and 2020 was $1.17, $2.50 and $2.32 per share, respectively. Employees contributed $234 and $205 to the ESPP during 2022
and  2021,  respectively.  Of  these  amounts,  $23  and  $22  at  December  31,  2022  and  2021,  respectively,  are  included  in  accrued  liabilities  in  the
accompanying balance sheets. As of December 31, 2022, there were 560,296 shares available for issuance under the ESPP.

Note 9 — Basic and Diluted Net Loss per Common Share

Basic and diluted net loss per share is computed using the weighted average number of shares of common stock outstanding during the period.
Common stock equivalents (using the treasury stock and “if converted” method) from stock options, unvested RSAs and RSUs, and warrants at December
31,  2022,  2021,  and  2020  were  5,494,153,  4,286,687  and  3,371,489,  respectively,  and  are  excluded  from  the  calculation  of  diluted  net  loss  per  share

issuance and delivery of the shares are deferred until the director retires from service as a director.

Note 10 — Related-Party Transactions

Harrow

The Chief Executive Officer of Harrow Health, Inc. (“Harrow”) was a member of the Company’s board of directors until March 17, 2021 when he
retired from service with the board. The Company issued 25,000 shares to the Harrow CEO in April 2021 after his retirement from the Company’s board
associated  with  RSUs  that  were  previously  fully  vested.  As  of  December  31,  2022,  Harrow  owned  1,982,000 shares  of  Eton’s  common  shares  which
represents 7.8% of the Company’s common shares outstanding.

In  March  2021,  the  Company  closed  its  laboratory  operation  in  Lake  Zurich,  Illinois  and  in  May  2021  it  reached  an  agreement  for  Imprimis

Pharmaceuticals, a subsidiary of Harrow, to purchase its lab equipment for $700 which was $181 above the Company’s net book value of the equipment.

Chief Executive Officer

The CEO has a partial interest in a company that the Company has partnered with for its EM-100/Alaway Preservative Free eye allergy product as

described below.

The  Company  acquired  the  exclusive  rights  to  sell  the  EM-100  product  in  the  United  States  pursuant  to  a  sales  and  marketing  agreement  (the
“Eyemax Agreement”) dated August 11, 2017 between the Company and Eyemax LLC (“Eyemax”), an entity affiliated with the Company’s CEO. The
Company also held a right of first refusal to obtain the exclusive license rights for geographic areas outside of the United States. Pursuant to the Eyemax
Agreement,  the  Company  was  responsible  for  all  costs  of  testing  and  FDA  approval  of  the  product,  other  than  the  FDA  filing  fee  which  was  paid  by
Eyemax.  The  Company  was  also  to  be  responsible  for  commercializing  the  product  in  the  United  States  at  its  expense.  The  Company  paid  Eyemax
$250  upon  execution  of  the  Eyemax  Agreement,  which  was  recorded  as  a  component  of  R&D  expense.  Under  the  terms  of  the  original  agreement,  the
Company would pay Eyemax $250 upon FDA approval and $500 upon the first commercial sale of the product and pay Eyemax a royalty of 10% on the
net sales of all products. The Eyemax Agreement was for an initial term of 10 years from the date of the Eyemax Agreement, subject to successive two-
year renewals unless the Company elected to terminate the Eyemax Agreement. 

On  February  18,  2019,  the  Company  entered  into  an  Amended  and  Restated  Agreement  with  Eyemax  amending  the  Sales  Agreement  (the
“Amended Agreement”). Pursuant to the Amended Agreement, Eyemax sold the Company all of its right, title and interest in EM-100, including any such
product  that  incorporates  or  utilizes  Eyemax’s  intellectual  property  rights.  Under  the  Amended  Agreement,  the  Company  assumed  certain  liabilities  of
Eyemax  under  its  Exclusive  Development  &  Supply  Agreement  with  Excelvision  SAS  dated  as  of  July  11,  2013,  as  amended  (the  “Excelvision
Agreement”), with respect to certain territories and arising during certain time periods. Pursuant to the Amended Agreement, the Company paid Eyemax
two milestone payments: (i) one milestone payment for $250 upon regulatory approval in the territory by the FDA of the first single agent product and (ii)
one milestone payment for $500 following the first commercial sale of the first single agent product in the territory. Following payment of the milestones,
the Company is entitled to retain all of the non-royalty transaction revenues and royalties up to $2,000 (the “Recovery Amount”). After the Company has
retained the full Recovery Amount, it is entitled to retain half of all royalty and non-royalty transaction revenue. The Company has realized $1,818 of the
non-royalty and royalty revenue as of December 31, 2022. The Amended Agreement also contains customary representations, warranties, covenants and
indemnities  by  the  parties.  The  EM-100  asset  and  its  associated  product  rights  were  sold  to  Bausch  Health  on  February  18,  2019  and  future  potential
royalties  of  twelve  percent  on  Bausch  Health  sales  of  the  product,  named  Alaway® Preservative  Free  by  Bausch,  which  was  approved  by  the  FDA  in
September 2020, will be split between Eyemax and the Company. The royalty from Bausch Health is subject to reduction if a competitive product with the
same active pharmaceutical ingredient is launched in the U.S. or if the product’s U.S market share falls below a specified target percentage. 

There were no amounts due to Eyemax under the terms of the Amended Agreement as of December 31, 2022 or December 31, 2021.

Note 11 — Leases

The Company recognizes a right-of-use (“ROU”) asset and a lease liability on the balance sheet for substantially all leases, including operating

leases, and separates lease components from non-lease components related to its office space lease.

On January 12, 2018, the Company signed an amended lease agreement to lease additional office space adjacent to its current corporate office
space in Deer Park, Illinois. The amended lease was scheduled to expire at the end of March 2021. In October 2020, the Company renewed its office lease
for  a  two-year  period  through  March  31,  2023  and  recorded  $195  in  ROU  assets  and  $195  in  operating  lease  liabilities  in  association  with  the  lease
extension. In November 2022, the Company renewed its office lease for a two-year period through March 31, 2025 and recorded $188 in ROU assets and
$188 in operating lease liabilities in association with the lease extension. On March 7, 2018, the Company entered into a lease for laboratory space at a
complex  in  Lake  Zurich,  Illinois.  The  lease  commenced  on  March  7,  2018  and  was  scheduled  to  expire  in  February  2021.  In  November  2020,  this
laboratory  lease  was  extended  to  June  2021  and  was  not  extended  after  that  date  as  the  Company  completed  an  evaluation  its  laboratory  operations
requirements and determined it would discontinue the laboratory activities and outsource its requirements.

The Company does not have any lease contracts that contain: (1) an option to extend that the Company is reasonably certain to exercise, (2) an
option to terminate that the Company is reasonably certain to exercise, or (3) an option to extend (or not to terminate) in which exercise of the option is
controlled  by  the  lessor.  Additionally,  the  Company  does  not  have  any  leases  with  residual  value  guarantees  or  material  restrictive  covenants.  Lease
liabilities and their corresponding right-of-use assets have been recorded based on the present value of the future lease payments over the expected lease
term. One of the Company’s lease agreements contains provisions for escalating rent payments over the term of the lease.

The Company’s leases do not contain readily determinable implicit discount rates, and therefore, the Company was required to use its incremental
borrowing rate of 7.8% to discount the future lease payments based on information available at lease commencement. In October 2020, the new discount
rate for the office lease extension was estimated at 5.4%. In November 2022, the new discount rate for an additional office lease extension was estimated at
8.6%. The incremental borrowing rate was estimated by determining the rate of interest that the Company would have to pay to borrow on a collateralized
basis over a similar term an amount equal to the lease payments in a similar economic environment.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Company’s operating lease cost as presented in the “Research and Development” and “General and Administrative” captions in the statements
of  operations  was  $0,  $9  and  $55  and  $82,  $86  and  $84  for  the  years  ended  December  31,  2022,  2021  and  2020,  respectively.  For  the  years  ended
December 31, 2022, 2021, and 2020, the Company recorded $87, $113, and $139,  respectively,  in  rent  expense.  Cash  paid  for  amounts  included  in  the
measurement of operating lease liabilities was $88 and $83 for years ended December 31, 2022 and 2021, respectively. The ROU asset amortization for
years ended December 31, 2022, 2021, and 2020 was $82, $88 and $129, respectively, and is reflected in depreciation and amortization in the Company’s
statements of cash flows. As of December 31, 2022, the weighted-average remaining lease term was 2.25 years, and the weighted-average discount rate
was 8.6%.

The  Company  has  a  federal  and  state  NOL  carryforward  of  $60,281  as  of  December  31,  2022.  Under  the  Tax  Act,  federal  NOLs  incurred  in
taxable years ending after December 31, 2017 in the amount of $54,629 may be carried forward indefinitely and are subject to an 80% usage limitation.
The deductibility of federal NOLs generated in tax years beginning before December 31, 2017 in the amount of $5,652 will expire in 2037. The state NOL
carry forward will begin to expire in 2029.

In  addition,  under  Sections  382  and  383  of  the  Internal  Revenue  Code  of  1986,  as  amended,  and  corresponding  provisions  of  state  law,  if  a
corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change (by value) in its equity ownership over a three-year
period, the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes (such as research tax credits) to offset its post-
change income may be limited.

Note 13 - Employee Savings Plan

The Company established an employee savings plan pursuant to Section 401(k) of the Internal Revenue Code, effective January 1, 2018. The plan
allows participating employees to deposit into tax deferred investment accounts up to 100% of their salary, subject to annual limits. The Company makes
certain matching contributions to the plan in amounts up to 4% of the participants’ annual cash compensation, subject to annual limits. For the years ended
December 31, 2022, 2021 and 2020, the Company made $172, $154 and $117, respectively, in matching contributions.

Note 14 — Commitments and Contingencies

Legal

The  Company  is  subject  to  legal  proceedings  and  claims  that  may  arise  in  the  ordinary  course  of  business.  The  Company  is  not  aware  of  any

pending or threatened litigation matters at this time that may have a material impact on the operations of the Company.

License and Product Development Agreements

The Company has entered into various agreements in addition to those discussed above which are described below.

The three oral solution pediatric neurology product candidates discussed below, Topiramate, Zonisamide and Lamotrigine were developed by the
Company and its various product candidate development partners and the Company subsequently sold all its rights and interests in these three products to
Azurity in 2021. The Company has recognized $22,000 in milestone revenues to date from these three products (including $5,000 received in 2022) and
may receive up to $20,000  in  additional  milestone  revenues  related  to  FDA  product  approvals  and  the  future  sales  levels  for  the  products.  Azurity  has
assumed royalty or profit share obligations owed to development partners as well as additional milestone payments based on sales volume targets.

During the years ended December 31, 2021 and 2020 the Company worked with Tulex Pharmaceuticals, Inc. (“Tulex”) as a third-party contract
manufacturer to develop an oral solution for Topiramate (fka ET-101) which targets a neurological condition. The Company subsequently filed the product
with the FDA in October 2020 and paid a $1,438 filing fee. In November 2021, the product received approval from the FDA and was launched by Azurity
in December 2021. The Company recognized a $5,000 milestone revenue at launch which was reflected in accounts receivable on the Company’s balance
sheet at December 31, 2021 and subsequently collected in January 2022.

On January 23, 2019, the Company entered into a Licensing and Supply Agreement (the “Agreement”) with Liquimeds Worldwide (“LMW”) for
Zonisamide oral liquid, a development stage product candidate (“ET-104”). Pursuant to the terms of the Agreement, the Company was to be responsible for
regulatory and marketing activities and LMW was responsible for development and manufacturing of ET-104. The Company paid $650 to  Azurity  upon
issuance  of  patent  covering  ET-104  listed  in  the  FDA’s  Orange  Book  in  November  2022  and  will  pay  $500 in  the  event  that  product  sales  in  excess  of
$10,000 were achieved within a calendar year.

On  June  12,  2019,  the  Company  entered  into  an  Exclusive  Licensing  and  Supply  Agreement  (the  “ET-105  License  Agreement”)  with  Aucta
Pharmaceuticals, Inc. (“Aucta”) for marketing rights in the United States to Lamotrigine, an oral suspension product candidate for use as an adjunct therapy
for partial seizures, primary generalized tonic-clonic seizures, and generalized seizures of Lennox-Gastaut syndrome in patients two years of age and older.
Pursuant to the terms of the ET-105 License Agreement, the Company was to be responsible for marketing activities and Aucta will be responsible for
development, manufacturing, and regulatory activities related to obtaining regulatory approval. The Company paid Aucta a licensing payment of $2,000 in
August 2019 upon receiving an acceptance for review letter from the FDA and will pay $2,450 upon FDA approval and commercial sales of the product
candidate and another $1,000 upon issuance of an Orange-book listed patent. If Aucta successfully completes a Lamotrigine product line extension product,
Eton will pay $1,500 upon FDA acceptance of the product filing. Aucta will be entitled to receive milestone payments from the Company of up to $3,000
based on commercial success of the product, including $1,000 when net sales exceed $10 million in a calendar year, and $2,000 when net sales exceed $20
million in a calendar year.

Azurity will assume royalty or profit share obligations owed to development partners as well as additional milestone payments based on sales volume

targets.

On March 27, 2020, the Company entered into an Exclusive Licensing and Supply Agreement (the “Alkindi License Agreement”) with Diurnal
for  marketing  ALKINDI  SPRINKLE®  in  the  United  States.  ALKINDI  SPRINKLE®’s  New  Drug  Application  (NDA)  was  approved  by  the  FDA  on
September 29, 2020 as a replacement therapy for pediatric patients with adrenocortical insufficiency.

For the initial licensing milestone fee, the Company paid Diurnal $3,500 in cash and issued 379,474 shares of its common stock to Diurnal which
were valued at $1,264 based on the Company’s closing stock price of $3.33 on March 26, 2020 (see Note 6). The total amount of $4,764 was recorded as a
component of research and development expense in the Company’s statement of operations for the year ended December 31, 2020. The Company will also
pay Diurnal $2,500 if the product obtains orphan drug exclusivity status from the FDA.

On June 15, 2021, the Company acquired U.S. and Canadian rights to Crossject’s ZENEO® hydrocortisone needleless autoinjector, which is under
development  as  a  rescue  treatment  for  adrenal  crisis.  The  Company  paid  Crossject  $500  upon  signing,  $500  in  March  2022  upon  a  completion  of  a
successful technical batch and could pay up to $3,500 in additional development milestones and up to $6,000 in commercial milestones, as well as a 10%
royalty on net sales.

On  October  28,  2021,  the  Company  acquired  the  U.S.  marketing  rights  to  Carglumic  Acid  Tablets.  The  product’s  Abbreviated  New  Drug
Application (“ANDA”), which is owned by Novitium Pharma, was approved by the FDA on October 12, 2021. The product is an AB-rated, substitutable
generic version of Carbaglu®. The Company paid $3,250 upon signing and retains 50%  of  the  product  profits  with  the  balance  being  distributed  to  the
licensor and manufacturer. The Company launched this product in December 2021.

In  June  2022,  the  Company  sold  its  rights  in  Cysteine  Hydrochloride,  Biorphen®,  and  Rezipres®  to  Dr.  Reddy’s.  Under  the  terms  of  the
transaction, Dr. Reddy’s assumed immediate ownership of Eton’s rights and interest in the products. The Company received $5,000 at closing, recorded as
licensing revenue in the twelve months ended December 31, 2022, and could receive up to $42,500 of additional payments based on the achievement of
certain event-based and sales-based milestones. Of the $5,000 received at closing, $250 was held in escrow to address potential indemnity claims during
the 12-month period following the effective date of the agreement. In addition, 10% of any additional payments paid by Dr. Reddy’s during the 12-month
period following the effective date will be held in escrow and subsequently released to Eton upon expiration of the 12-month period following the effective
date. In accordance with the terms of the agreement, $812 of Sintetica profit share receivables were expensed as cost of goods sold in the twelve months
ended December 31, 2022.

On September 13, 2022, the Company acquired an FDA-approved ANDA for Betaine Anhydrous for oral solution. The ANDA was approved by
the FDA on January 28, 2022. The Company paid $2,000 upon signing and could pay up to $1,000 in commercial milestones. The Company will retain
65% of the product profits with the balance being distributed to the licensor.

Indemnification

As permitted under Delaware law and in accordance with the Company’s Amended and Restated Bylaws, the Company is required to indemnify
its officers and directors for certain events or occurrences while the officer or director is or was serving in such capacity. The Company is also party to
indemnification agreements with its directors and officers. The Company believes the fair value of the indemnification rights and agreements is minimal.
Accordingly, the Company has not recorded any liabilities for these indemnification rights and agreements as of December 31, 2022 or 2021.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

We  maintain  “disclosure  controls  and  procedures,”  as  such  term  is  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Exchange Act,  that  are
designed  to  ensure  that  information  required  to  be  disclosed  by  us  in  reports  that  we  file  or  submit  under  the  Exchange  Act  is  recorded,  processed,
summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our
management, including our principal executive officer and our principal financial officer, to allow timely decisions regarding required disclosure.

The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there

can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

As of December 31, 2022, an evaluation was conducted under the supervision and with the participation of our management, including our Chief
Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures. Based on this evaluation, such officers have
concluded that our disclosure controls and procedures are effective as of December 31, 2022.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for our Company, as such term
is defined in Rule 13a-15(f) under the Exchange Act. Our management conducted an evaluation, with the participation of our principal executive officer
and principal financial officer, of the effectiveness of our internal control over financial reporting as of December 31, 2022, based on the criteria set forth in
the  2013  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  this
evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2022.

This report does not include an attestation report of our independent registered public accounting firm regarding our internal control over financial

reporting, in accordance with applicable SEC rules that permit us to provide only management’s report in this report.

Changes in Internal Control over Financial Reporting

There  has  not  been  any  change  in  our  internal  control  over  financial  reporting  (as  defined  in  Rules  13a-15(f)  under  the  Exchange  Act)  that
occurred during the quarter ended December 31, 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over
financial reporting.

79

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and principal financial officer, do not expect that our disclosure controls or our internal
control over financial reporting will prevent or detect all errors and all fraud. 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.  The  design  of  a  control  system  must  reflect  the  fact  that  there  are
resource  constraints,  and  the  benefits  of  controls  must  be  considered  relative  to  their  costs.  Further,  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,  if  any,  have  been  detected. These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty  and  that
breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or
more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood
of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of
any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions
or deterioration in the degree of compliance with policies or procedures.
