Item 1. Business

Overview

PART I

We are a physician-led biopharmaceutical company focused on immuno-inflammatory diseases.  We currently have a pipeline of drug
candidates focused on immuno-inflammatory diseases, as well as one product approved by the U.S. Food and Drug Administration, or FDA, that
we  are  not  currently  distributing,  marketing  or  selling,  and  other  investigational  drug  candidates.  In  September  2019,  we  announced  the
completion of a strategic review of our business, as a result of which we are refocusing our resources on our immuno-inflammatory development
programs.  We  plan  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates  and  ESKATA  (hydrogen  peroxide)  topical  solution,  40%
(w/w), or ESKATA, our non-marketed FDA-approved product.

Our Drug Candidates Currently in Development

Our pipeline of drug candidates that we are currently developing is summarized in the table below:

MK2 Inhibitors, JAK Inhibitors and ITK Inhibitors as Potential Treatments for Immuno-Inflammatory Diseases

In 2017, we acquired Confluence Life Sciences, Inc. (now known as Aclaris Life Sciences, Inc.), or Confluence.  The acquisition of
Confluence  added  small  molecule  drug  discovery  and  preclinical  development  capabilities  that  allowed  us  to  bring  early-stage  research  and
development activities in-house that we previously outsourced to third parties.  We also earn revenue from Confluence’s provision of contract
research services to third parties. We intend to leverage our proprietary drug discovery platform acquired from Confluence, called KINect, to
identify potential drug candidates that we may develop independently or in collaboration with third parties. We also acquired several preclinical
drug  candidates,  including  inhibitors  of  the  mitogen-activated  protein  kinase-activated  protein  kinase  2,  or  MK2,  signaling  pathway,  topical
Janus kinase, or JAK, inhibitors known as soft-JAK inhibitors, and inhibitors of interleukin-2-inducible T cell kinase, or ITK.

We  submitted  an  Investigational  New  Drug  Application,  or  IND,  in  April  2019  for  ATI-450,  an  investigational  oral,  novel,  small
molecule selective MK2 inhibitor compound, for the treatment of rheumatoid arthritis, which was allowed by the FDA in May 2019.  MK2 is a
key  regulator  of  pro-inflammatory  mediators  including  TNFα,  IL1β,  IL6,  IL8  and  other  essential  pathogenic  signals  in  chronic  immuno-
inflammatory diseases, as well as in cancer.  As an oral drug candidate, we are developing ATI-450 as a potential alternative to injectable anti-
TNF/IL1/IL6 biologics for treating

4

 
 
 
 
 
 
 
Table of Contents

certain immuno-inflammatory diseases. We initiated a Phase 1 single and multiple ascending dose clinical trial in 77 healthy subjects in August
2019. Preliminary data from this trial demonstrated that ATI-450 resulted in marked inhibition of TNFα, IL1β, IL8 and IL6. We also observed
that ATI-450 had dose-proportional pharmacokinetics with a terminal half-life of 9-12 hours in the multiple ascending dose cohort, and had no
meaningful food effect or drug-drug interaction with methotrexate.  ATI-450 was generally well-tolerated at all doses tested in the trial.  The
most common adverse events (reported by 2 or more subjects who received ATI-450) observed during the trial were dizziness, headache, upper
respiratory tract infection, constipation, abdominal pain, and nausea.  Based on the results of the Phase 1 trial, we  intend to initiate a Phase 2a
clinical trial for ATI-450 in subjects with rheumatoid arthritis in the first half of 2020. We are also planning to initiate a Phase 2a clinical trial of
ATI-450 for an additional immuno-inflammatory indication.

We  expect  to  submit  an  IND  for  ATI-1777,  an  investigational  topical  soft-JAK  inhibitor  compound,  for  the  treatment  of  atopic
dermatitis in mid-2020.  Soft-JAK inhibitors are designed to be topically applied and active in the skin, but rapidly metabolized and inactivated
when they enter the bloodstream, which may result in low systemic exposure. If the IND is allowed, we expect to initiate a Phase 1/2 clinical trial
in healthy subjects and subjects with atopic dermatitis in the second half of 2020 evaluating ATI-1777 as a potential treatment for moderate-to-
severe atopic dermatitis.

We  are  also  developing  ATI-2138,  our  investigational  oral  ITK/TXK/JAK3,  or  ITJ,  inhibitor  compound,  as  a  potential  treatment  for
psoriasis  and/or  inflammatory  bowel  disease,  which  are  both  T-cell  mediated  autoimmune  diseases.    The  ITJ  compound  interrupts  T  cell
signaling through the combined inhibition of ITK/TXK/JAK3 pathways in lymphocytes. We expect to file an IND for ATI-2138 in the fourth
quarter of 2020 or the first quarter of 2021.

Our Other Drug Candidates and FDA-Approved Product

A-101 45% Topical Solution as a Potential Treatment for Common Warts

We  are  developing  a  high-concentration  formulation  of  hydrogen  peroxide,  A-101  45%  Topical  Solution,  as  a  potential  prescription
treatment for common warts, also known as verruca vulgaris.  Although common warts are generally not harmful, and in most cases, eventually
clear without medical treatment, they may be painful and aesthetically unattractive and are contagious.  On an annual basis, approximately 2.0
million people in the United States are diagnosed with common warts. Cryosurgery is the most frequently used in-office treatment for common
warts.    Common  warts  can  also  be  treated  with  over-the-counter  products,  such  as  those  containing  salicylic  acid.   We  are  not  aware  of  any
prescription drugs that have been approved by the FDA for the treatment of common warts.    

In September 2018, we commenced two pivotal Phase 3 clinical trials, which we refer to as THWART-1 and THWART-2, evaluating a
twice-weekly dosing regimen of A-101 45% Topical Solution for the treatment of common warts. In each of the THWART-1 trial and THWART-
2  trial,  which  we  completed  in  October  2019  and  September  2019,  respectively,  subjects  treated  with  A-101  45%  Topical  Solution  achieved
clinically  meaningful  and  statistically  significant  outcomes  for  the  primary  and  secondary  efficacy  endpoints.    No  treatment-related  serious
adverse events were observed in the trials. The most common adverse events occurring in more than 5% of subjects in the A-101 45% Topical
Solution group were adverse events at the application site such as pain, scabbing, erythema, pruritus, pallor and erosion.

In February 2019, we commenced an open-label safety extension trial investigating A-101 45% Topical Solution as a potential treatment

for common warts.

We are pursuing strategic alternatives, including seeking a partner, to obtain regulatory approval and commercialize A-101 45% Topical

Solution as a potential treatment for common warts.

ATI-501 and ATI-502 as a Potential Treatment for Alopecia

In 2015, we in-licensed exclusive, worldwide rights from Rigel Pharmaceuticals, Inc., or Rigel, to certain inhibitors of the JAK family
of enzymes, which we refer to as ATI-501 and ATI-502, an oral and topical formulation, respectively, for specified dermatological conditions,
including alopecia areata, or AA, androgenetic alopecia, or AGA, also known as male or female pattern baldness, vitiligo and atopic dermatitis.
 We are pursuing strategic alternatives, including seeking a partner, to further develop, obtain regulatory approval and commercialize ATI-501
and ATI-502 as potential treatments for alopecia.

ESKATA for the Treatment of Raised Seborrheic Keratosis

ESKATA, our only FDA-approved product, is a proprietary formulation of high-concentration hydrogen peroxide topical solution which
was approved by the FDA in December 2017 as an office-based prescription treatment for raised seborrheic keratosis, or SK, a common non-
malignant skin tumor.

We  launched  ESKATA  in  the  United  States  in  May  2018.    In  August  2019,  we  voluntarily  discontinued  the  commercialization  of
ESKATA in the United States, but we continue to maintain the New Drug Application, or NDA, for ESKATA in the United States.  We also
withdrew the marketing authorizations we had previously received for the product in all countries outside of the United States. We are pursuing
strategic alternatives, including seeking a strategic partner, to commercialize ESKATA.

Our Commercial Product Which We Have Divested

RHOFADE for the Treatment of Persistent Facial Erythema (Redness) Associated with Rosacea in Adults

In  November  2018,  we  acquired  RHOFADE  (oxymetazoline  hydrochloride)  cream,  1%,  or  RHOFADE,  which  included  an  exclusive
license  to  certain  intellectual  property  for  RHOFADE,  as  well  as  additional  intellectual  property,  from  Allergan  Sales,  LLC,  or  Allergan.    In
October 2019, we sold the worldwide rights to RHOFADE, which included the assignment of certain licenses for related intellectual property
assets, to EPI Health, LLC, or EPI Health, as described further below under “—Acquisitions and License Agreements.”

Manufacturing and Supply

We do not have any manufacturing facilities.  We rely on third parties for the manufacture of preclinical and clinical supplies for all of

our drug candidates.

We  have  entered  into  an  exclusive,  ten-year,  automatically  renewable  supply  agreement  with  PeroxyChem  LLC,  or  PeroxyChem,  to
provide hydrogen peroxide, the active pharmaceutical ingredient, or API, that is used in A-101 45% Topical Solution for the potential treatment
of common warts and ESKATA for the treatment of raised SKs.  The ten-year term commenced on the date of first commercial sale of ESKATA
in  the  United  States.  We  or  PeroxyChem  may  terminate  the  supply  agreement  with  prior  written  notice  immediately  for  specified  financial
reasons, after a 10-business day and 60-day cure period for material monetary and material non-monetary breaches, respectively, and in the event
of a force majeure event, that continues for 90 consecutive days. In addition, we may terminate the PeroxyChem supply agreement, with prior
written notice, for PeroxyChem’s failure to supply API to us for more than 90 cumulative days in a year. We may assign the agreement without
the consent of PeroxyChem in connection with the sale, transfer or license of the products covered by the agreement.

We  have  entered  into  an  exclusive  commercial  supply  agreement  with  James  Alexander  Corporation,  or  James  Alexander,  for  the
manufacture of the finished dosage form of A-101 45% Topical Solution and ESKATA.  We must meet a minimum purchase requirement each
year through 2022.  In the event that we do not meet the minimum purchase requirements, James Alexander may, at its discretion, convert the
agreement  into  a  non-exclusive  agreement.    Additionally,  during  the  term  of  the  agreement,  James  Alexander  will  not  manufacture  any
competitive  product,  as  defined  in  the  agreement.  The  term  of  the  agreement  with  James  Alexander  is  five  years  from  the  date  of  the  first
commercial sale of ESKATA in the United States and thereafter will be renewed automatically for one-year periods. Either party may terminate
the  agreement  for  any  reason  upon  180  days  prior  written  notice.  In  addition,  either  party  has  the  right  to  immediately  terminate  the  supply
agreement  under  certain  circumstances,  including  (i)  the  other  party  files  for  bankruptcy,  (ii)  the  other  party  materially  breaches  the  supply
agreement and such breach is not cured within a specified period and (iii) any required license, permit or certificate required of the other party to
perform its obligations under the supply agreement is not approved or issued or is revoked by an applicable governmental regulatory authority.
We may assign the agreement without the consent of James Alexander in connection with the sale of the products to which the agreement relates.

Competition

The  pharmaceutical  industry  is  characterized  by  rapidly  advancing  technologies,  intense  competition  and  a  strong  emphasis  on

proprietary drugs. While we believe that our knowledge, experience and scientific resources provide us with

6

 
   
 
 
 
 
 
 
 
 
 
Table of Contents

competitive  advantages,  we  face  potential  competition  from  many  different  sources,  including  major  pharmaceutical,  biotechnology  and
specialty  pharmaceutical  companies,  academic  institutions  and  governmental  agencies  and  public  and  private  research  institutions.  Our  drug
candidates, if approved, will compete with existing treatments and new treatments that may become available in the future.

With  respect  to  A-101  45%  Topical  Solution  for  the  treatment  of  common  warts,  we  are  aware  of  the  following  companies  that  are
developing a drug candidate for the treatment of common warts: Nielsen BioSciences, Inc. and Verrica Pharmaceuticals Inc. In addition, there are
over-the-counter drugs for the treatment of common warts and other drugs that have been used off-label as treatments for common warts.

With respect to ATI-450 as a potential treatment for rheumatoid arthritis, there are numerous commercial products, such as anti-TNFs,
anti-IL6s, anti-IL1s and JAK inhibitors, approved for the treatment of rheumatoid arthritis. In addition, we are aware of a number of companies
conducting late-stage clinical trials for investigational drug candidates for the treatment of rheumatoid arthritis.

The  commercial  opportunity  for  our  drug  candidates,  if  approved,  could  be  reduced  or  eliminated  if  our  competitors  develop  and
commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any
drug that we may develop. Our competitors also may obtain FDA or other regulatory approval for their drug candidates more rapidly than our
potential third-party partners may obtain approval for our drug candidates, which could result in our competitors establishing a strong market
position before our drug candidates are able to enter the market.

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

Intellectual Property

Our success depends in large part upon our ability to obtain and maintain proprietary protection for our drug candidates and to operate
without  infringing  the  proprietary  rights  of  others.  We  seek  to  avoid  the  latter  by  monitoring  patents  and  publications  that  may  affect  our
business,  and  to  the  extent  we  identify  such  developments,  evaluate  and  take  appropriate  courses  of  action.  Our  policy  is  to  protect  our
proprietary position by, among other methods, filing patent applications on inventions that are important to the development and conduct of our
business with the U.S. Patent and Trademark Office, or USPTO, and its foreign counterparts.

With respect to our inhibitors of the MK2 signaling pathway, we own two U.S. patents and pending applications in the European Union
and other foreign countries that cover ATI-450, our lead candidate, and certain methods of use.  The U.S. patents expire in 2034 and any claims
that issue from the pending applications expire in 2034, subject to any applicable patent term adjustment or extension that may be available in a
particular country.  We also own numerous U.S. patents and pending foreign patent applications directed to other inhibitors of the MK2 signaling
pathway, which expire or will expire between 2031 and 2034, subject to any applicable patent term adjustment or extension that may be available
in a particular country. 

With  respect  to  our  soft-JAK  inhibitors,  we  have  filed  two  U.S.  and  PCT  applications  directed  to  various  novel  inhibitors  of  JAK1
and/or JAK3, including ATI-1777, and methods of using the same.  Any claims that may issue would expire in 2038, subject to any applicable
patent term adjustment or extension that may be available in a particular country.

With respect to our ITK inhibitors, we own multiple U.S. patents and pending applications in the United States and foreign countries
directed to novel inhibitors of ITK, including pending U.S. and PCT applications to ATI-2138, and methods of using the same.  The patents and
pending  applications,  if  issued,  expire  between  2035  and  2039,  subject  to  any  applicable  patent  term  adjustment  or  extension  that  may  be
available in a particular country.

of  various  skin  conditions  including  SK,  acrochordons,  corns,  tags,  acne,  warts  and  rosacea.  The  patents  in  Germany,  the  United  Kingdom,
Mexico and Singapore include claims that cover the use of high-concentration hydrogen peroxide of at least 23%, including A-101 45% Topical
Solution and ESKATA, for the alleviation of acrochordons. The issued patents relating to the use of A-101 45% Topical Solution and ESKATA
begin to expire in 2022, subject to any applicable patent term extension that may be available in a particular country.

We also own four issued U.S. patents and pending U.S., European and other foreign patent applications directed to various formulations
comprising high-concentration hydrogen peroxide, including A-101 45% Topical Solution and ESKATA, dosing regimens for such formulations,
applicators  for  use  with  such  formulations,  and  methods  of  treating  various  skin  conditions,  including  SK  and  common  warts,  by  the  topical
administration of such formulations.  Our U.S. formulation, method of use and applicator patents expire in 2035 and any claims that issue from
the pending formulation applications will expire in 2035, subject to any applicable patent term adjustment or extension that may be available in a
particular country.

We  also  use  other  forms  of  protection,  such  as  trademark,  copyright,  and  trade  secret  protection,  to  protect  our  intellectual  property,
particularly where we do not believe patent protection is appropriate or obtainable. We aim to take advantage of all of the intellectual property
rights that are available to us and believe that this comprehensive approach will provide us with proprietary positions for our drug candidates,
where available.

Patents extend for varying periods according to the date of patent filing or grant and the legal term of patents in various countries where
patent protection is obtained. The actual protection afforded by a patent, which can vary from country to country, depends on the type of patent,
the scope of its coverage and the availability of legal remedies in the country. In most countries in which we file, the patent term is 20 years from
the  earliest  date  of  filing  a  non-provisional  patent  application.  In  the  United  States,  a  patent  term  may  be  shortened  if  a  patent  is  terminally
disclaimed over another patent or as a result of delays in patent prosecution by the patentee, and a patent’s term may be lengthened by patent
term adjustment, which compensates a patentee for administrative delays by the USPTO in granting a patent or by patent term extension, which
compensates  a  patentee  for  delays  at  the  FDA.  The  patent  term  of  a  European  patent  is  20  years  from  its  filing  date;  however,  unlike  in  the
United States, the European patent does not grant patent term adjustments. The European Union does have a compensation program similar to
patent term extension called supplementary patent certificate that would effectively extend patent protection for up to five years.

We  also  protect  our  proprietary  information  by  requiring  our  employees,  consultants,  contractors  and  other  advisors  to  execute
nondisclosure and assignment of invention agreements upon commencement of their respective employment or engagement. Agreements with
our employees also prevent them from bringing the proprietary rights of third parties to us. In addition, we also require confidentiality or service
agreements from third parties that receive our confidential information or materials.

Acquisition and License Agreements 

Agreement and Plan of Merger with Confluence

In  August  2017,  we  entered  into  an  Agreement  and  Plan  of  Merger,  or  the  Confluence  Agreement,  with  Confluence,  Aclaris  Life
Sciences,  Inc.,  our  wholly-owned  subsidiary,  or  Merger  Sub,  and  Fortis  Advisors  LLC,  as  representative  of  the  equity  holders  of
Confluence.  Pursuant to the terms of the Confluence Agreement, the Merger Sub merged with and into Confluence, with Confluence surviving
as our wholly-owned subsidiary, resulting in our acquisition of 100% of the outstanding shares of Confluence.  We paid $10.3 million in cash and
issued 349,527 shares of our common stock with a fair value of $9.7 million to the Confluence equity holders. 

In  November  2018,  we  achieved  a  development  milestone  specified  in  the  Confluence  Agreement.    The  milestone  payment  to  the
former  Confluence  equity  holders  was  comprised  of  $2.5  million  in  cash  and  253,208  shares  of  our  common  stock  with  a  fair  value  of  $2.2
million.  We also agreed to pay the former Confluence equity holders aggregate remaining contingent consideration of up to $75.0 million, based
upon the achievement of specified regulatory and commercial milestones set forth in the Confluence Agreement. In addition, we have agreed to
pay  the  former  Confluence  equity  holders  future  royalty  payments  calculated  as  a  low  single-digit  percentage  of  annual  net  sales,  subject  to
specified reductions, limitations and other adjustments, until the date that all of the patent rights for that product have expired, as determined on a
country-by-country  and  product-by-product  basis  or,  in  specified  circumstances,  ten  years  from  the  first  commercial  sale  of  such  product.    In
addition, if we sell, license or transfer any of the intellectual property acquired from Confluence to a third party, we will be obligated to pay the
former Confluence equity holders a portion of any incremental consideration (in excess of the development and milestone payments described
above) that we receive from such sale, license or transfer in specified circumstances. 

License Agreement with Rigel

In  August  2015,  we  entered  into  an  exclusive,  worldwide  license  and  collaboration  agreement  with  Rigel  for  the  development  and
commercialization  of  products  containing  two  specified  JAK  inhibitors,  ATI-501  and  ATI-502,  or  the  Rigel  License  Agreement,  which  we
amended  in  October  2019.  Under  this  agreement,  we  may  develop  these  JAK  inhibitors  for  the  treatment  of  AA  and  other  dermatological
conditions. We are required to use commercially reasonable efforts to develop, seek regulatory approval and commercialize at least one product,
which is deemed satisfied by us using commercially reasonable efforts to find a third party to use commercially reasonable efforts to develop,
seek  regulatory  approval  and  commercialize  at  least  one  product.  We  paid  Rigel  an  upfront  nonrefundable  payment  of  $8.0  million  and  $4.0
million upon  the  achievement  of  a  specified  development  milestone,  and  have  agreed  to  make  remaining  aggregate  payments  of  up  to  $76.0
million upon the achievement of specified development milestones, such as clinical trials and regulatory approvals. Further, we have agreed to
pay up to an additional $10.5 million to Rigel upon the achievement of a second set of development milestones. In addition, in connection with
the amendment of the agreement in October 2019, we agreed to pay Rigel an amendment fee of $1.5 million in three installments of $0.5 million
in January 2020, April 2020 and July 2020. With respect to any products we commercialize under the Rigel License Agreement, we will pay
Rigel quarterly tiered royalties on our annual net sales of each product at a high single-digit percentage of annual net sales, subject to specified
reductions,  until  the  date  that  all  of  the  patent  rights  for  that  product  have  expired,  as  determined  on  a  country-by-country  and  product-by-
product basis or, in specified countries under specified circumstances, ten years from the first commercial sale of such product.

The Rigel License Agreement terminates on the date of expiration of all royalty obligations unless earlier terminated by either party for
a material breach. We may also terminate the Rigel License Agreement without cause at any time upon advance written notice to Rigel. Rigel,
after consultation with us, will be responsible for maintaining and prosecuting the patent rights, and we will have final decision-making authority
regarding  such  patent  rights  for  a  product  in  the  United  States  and  the  European  Union.  To  the  extent  that  we  jointly  develop  intellectual
property, we will confer and decide which party will be responsible for filing, prosecuting and maintaining those patent rights. The Rigel License

Agreement  also  establishes  a  joint  steering  committee  composed  of  an  equal  number  of  representatives  for  each  party,  which  will  monitor
progress of the development of products.

Stock Purchase Agreement with Vixen Pharmaceuticals, Inc.

In March 2016, we entered into a stock purchase agreement, or the Vixen Agreement, with Vixen and JAK1, LLC, JAK2, LLC and
JAK3,  LLC,  or  together,  the  Selling  Stockholders,  and  Shareholder  Representative  Services  LLC,  as  the  representative  of  the  Selling
Stockholders.    Pursuant  to  the  Vixen  Agreement,  we  acquired  all  shares  of  Vixen’s  capital  stock  from  the  Selling  Stockholders,  or  the  Vixen
Acquisition.    Following  the  Vixen  Acquisition,  Vixen  became  our  wholly-owned  subsidiary.    We  paid  $0.6  million  upfront  and  issued  an
aggregate  of  159,420  shares  of  our  common  stock  to  the  Selling  Stockholders.  We  are  obligated  to  make  annual  payments  of  $0.1  million
through March 2022, with such amounts being creditable against specified future payments that may be paid under the Vixen Agreement.

Under the Vixen Agreement, we agreed to use commercially reasonable efforts to develop and commercialize at least one product for
the treatment of AA and at least one product for the treatment of AGA, in each case for commercial sale and distribution throughout the United
States and such other areas of the world as we determine to be commercially prudent.  In the event we do not comply with these obligations, we
are obligated to license, on a non-exclusive basis, certain intellectual property rights related to the products to the Selling Stockholders or their
designee, on terms to be mutually agreed to by the parties, among other rights exercisable by the Selling Stockholders.

Under the Vixen Agreement, we are obligated to make aggregate payments of up to $18.0 million to the Selling Stockholders upon the
achievement  of  specified  pre-commercialization  milestones  for  three  products  covered  by  the  Vixen  patent  rights  in  the  United  States,  the
European  Union  and  Japan,  and  aggregate  payments  of  up  to  $22.5  million  upon  the  achievement  of  specified  commercial  milestones  for
products covered by the Vixen patent rights. With respect to any covered products that we commercialize under the Vixen Agreement, we are
obligated to pay low single-digit royalties on net sales, subject to specified reductions, limitations and other adjustments, until the date that all of
the  patent  rights  for  that  product  have  expired,  as  determined  on  a  country-by-country  and  product-by-product  basis  or,  in  specified
circumstances, ten years from the first commercial sale of such product. If we sublicense any of Vixen’s patent rights and know-how acquired
pursuant  to  the  Vixen  Agreement,  we  will  be  obligated  to  pay  a  portion  of  any  consideration  we  receive  from  such  sublicenses  in  specified
circumstances. 

License Agreement with Columbia University 

As a result of the Vixen Acquisition, we became party to the Exclusive License Agreement, by and between Vixen and the Trustees of
Columbia  University  in  the  City  of  New  York,  or  Columbia,  dated  as  of  December  31,  2015,  or  as  amended,  the  Columbia  License
Agreement.  Pursuant to the Columbia License Agreement, we have an exclusive, worldwide license under specified Columbia patent rights and
a  non-exclusive,  worldwide  license  under  specified  Columbia  know-how  in  all  fields  to  develop  and  commercialize  a  product  that  otherwise
infringes a Columbia patent right or uses Columbia know-how.  Our rights to this Columbia intellectual property cover the use of specified JAK
inhibitor compounds for the potential treatment of AA, AGA and other dermatological conditions. 

We are obligated to pay Columbia an annual license fee of $10,000, subject to specified adjustments for patent expenses incurred by
Columbia and creditable against any royalties that may be paid under the Columbia License Agreement. We are also obligated to pay up to an
aggregate of $11.6 million upon the achievement of specified commercial milestones, including specified levels of net sales of products covered
by Columbia patent rights and/or know-how, and royalties at a sub-single-digit percentage of annual net sales of products covered by Columbia
patent  rights  and/or  know-how,  subject  to  specified  adjustments.  If  we  sublicense  any  of  Columbia’s  patent  rights  and  know-how  acquired
pursuant  to  the  Columbia  License  Agreement,  we  will  be  obligated  to  pay  Columbia  a  portion  of  any  consideration  received  from  such
sublicenses in specified circumstances.  The royalties, as determined on a country-by-country and product-by-product basis, are payable until the
date that all of the patent rights for that product have expired, the expiration of any market exclusivity period granted by a regulatory body or, in
specified circumstances, ten years from the first commercial sale of such product.

We  have  agreed  to  use  commercially  reasonable  efforts  to  develop  and  commercialize  at  least  one  product.  In  the  event  we  do  not
comply with this obligation, Columbia has the option to terminate the license or convert the exclusive patent license to a non-exclusive patent
license. Further, in the event we do not comply with our obligations under the Vixen Agreement to develop and commercialize products, our
rights under the Columbia License Agreement may revert

10

 
 
 
 
 
 
 
 
Table of Contents

to a party to be designated by the Selling Stockholders.  Columbia is responsible for maintaining and prosecuting the patent rights, giving due
consideration to our reasonable comments related thereto.

The Columbia License Agreement terminates on the date of expiration of all royalty obligations thereunder unless earlier terminated by
either party for a material breach, subject to a specified cure period. We may also terminate the Columbia License Agreement without cause at
any time upon advance written notice to Columbia.

Asset Purchase Agreement with EPI Health

In October 2019, we entered into an Asset Purchase Agreement, or APA, with EPI Health, pursuant to which we sold the worldwide

rights to RHOFADE, which included the assignment of certain licenses for related intellectual property assets, or the Disposition. 

Pursuant  to  the  APA,  EPI  Health  paid  us  an  upfront  payment  of  $35.0  million  ($1.75  million  of  which  was  placed  in  escrow)  and
$200,000  for  inventory.    In  addition,  EPI  Health  has  agreed  to  pay  us  (i)  potential  sales  milestone  payments  of  up  to  $20.0  million  in  the
aggregate upon the achievement of specified levels of net sales (as defined in the APA) of products covered by the APA, (ii) a specified high
single-digit royalty calculated as a percentage of net sales, on a product-by-product and country-by-country basis, until the date that the patent
rights related to a particular product, such as RHOFADE, have expired, provided, that with respect to sales of RHOFADE in any territory outside
of the United States, such royalty shall be paid on a country-by-country basis until the date that the RHOFADE patent rights in the particular
country have expired or, if later, 10 years from the date of the first commercial sale of RHOFADE in such country and (iii) 25% of any upfront,
license, milestone, maintenance or fixed payment received by EPI Health in connection with any license or sublicense of the assets transferred in
the Disposition in any territory outside of the United States, subject to specified exceptions.  In addition, EPI Health has agreed to assume our
obligation  to  pay  specified  royalties  and  milestone  payments  under  our  existing  agreements  with  Allergan,  Aspect  Pharmaceuticals,  LLC  and
Vicept Therapeutics, Inc.

Assignment Agreement with the Estate of Mickey Miller and Finder’s Services Agreement with KPT Consulting, LLC

In  August  2012,  we  entered  into  an  assignment  agreement,  or,  as  amended,  the  Assignment  Agreement,  with  the  Estate  of  Mickey
Miller,  or  the  Miller  Estate,  under  which  we  acquired  some  of  the  intellectual  property  rights  covering  A-101  45%  Topical  Solution  and
ESKATA.    The  assignment  of  intellectual  property  rights  covers  specified  know-how,  along  with  modifications  of,  improvements  to  and
variations  on  A-101  that  meet  defined  chemical  properties.  Under  this  agreement,  we  have  the  sole  and  exclusive  right,  but  not  the  duty,  to
develop, obtain marketing approval for and commercialize A-101 45% Topical Solution and ESKATA in various countries throughout the world.
We  are  required  to  use  commercially  reasonable  efforts  to  develop  and  commercialize  at  least  one  product  for  at  least  one  indication  in  the
United States. In connection with obtaining the assignment of the intellectual property from the Miller Estate, in August 2012 we also entered
into a separate finder’s services agreement, or the Finder’s Services Agreement, with KPT Consulting, LLC. 

Under  the  terms  of  the  Assignment  Agreement  and  the  Finder’s  Services  Agreement,  we  made  aggregate  upfront  payments  of  $0.6
million in 2012 and one-time milestone payments of $0.4 million in 2013 upon the dosing of the first human subject with ESKATA in our Phase
2 clinical trial. There are no remaining potential milestone payments under the Assignment Agreement. Under the Finder’s Services Agreement,
we made a one-time milestone payment of $1.0 million in April 2017 upon the achievement of a specified regulatory milestone, and a one-time
milestone payment of $1.5 million in May 2018 upon the achievement of a specified commercial milestone.  Under the terms of the Finder’s
Services Agreement, we are obligated to make an additional milestone payment of $3.0 million upon the achievement of a specified commercial
milestone.  Under each of the Assignment Agreement and the Finder’s Services Agreement, we are also obligated to pay royalties on sales of
ESKATA and related products, at low single-digit percentages of net sales, subject to reduction in specified circumstances. Both agreements will
terminate upon the expiration of the last pending, viable patent claim of the patents acquired under the Assignment Agreement, but no sooner
than 15 years from the effective date of the agreements.

Government Regulation and Product Approval

Governmental  authorities  in  the  United  States,  at  the  federal,  state  and  local  level,  and  analogous  authorities  in  other  countries
extensively regulate, among other things, the research, development, testing, manufacture, safety surveillance, efficacy, quality control, labeling,
packaging,  distribution,  record  keeping,  promotion,  storage,  advertising,  distribution,  marketing,  sale,  export  and  import,  and  the  reporting  of
safety and other post-market information of products such as the ones we are developing. A drug candidate must be approved by the FDA before
it may be legally promoted in the United States and by comparable foreign regulatory authorities before marketing in other jurisdictions.  The
process of obtaining regulatory approvals and the subsequent compliance with applicable federal, state, local and foreign statutes and regulations
require the expenditure of substantial time and resources. Failure to comply with the applicable U.S. requirements at any time during the product
development  process,  approval  process  or  after  approval  may  subject  an  applicant  and/or  sponsor  to  a  variety  of  administrative  or  judicial
sanctions,  including  refusal  by  regulatory  authorities  to  approve  applications,  withdrawal  of  an  approval,  imposition  of  a  clinical  hold,
import/export delays, issuance of warning letters and untitled letters, product recalls, product seizures, total or partial suspension of production or
distribution,  injunctions,  fines,  refusals  of  government  contracts,  restitution,  disgorgement  of  profits,  or  civil  or  criminal  investigations  and
penalties brought by FDA and the Department of Justice or other governmental entities.

United States Government Regulation

NDA Approval Processes

In the United States, the FDA regulates drug and medical device products under the Federal Food, Drug, and Cosmetic Act, or FDCA,
and  its  implementing  regulations.    The  FDA’s  Center  for  Drug  Evaluation  and  Research  has  primary  jurisdiction  over  the  premarket
development, review and approval of our drug candidates. Accordingly, we are investigating our drug candidates pursuant to IND applications
and expect that any third-party partners that we may consummate a transaction with would seek approval through the NDA pathway.  A-101 45%
Topical Solution is comprised of both a drug component (the hydrogen peroxide solution) and a pen-type applicator. Based on our discussions
with  the  FDA  to  date,  we  do  not  anticipate  that  the  FDA  will  require  the  submission  of  a  separate  marketing  application  for  the  pen-type
applicator that will be used with A-101 45% Topical Solution for the treatment of common warts, but this could change during the course of the
FDA’s review of the NDA.

An applicant seeking approval to market and distribute a new drug product in the United States must typically undertake the following:

·

·
·

·

·
·
·

·
·

completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s good laboratory practice
regulations;
submission to the FDA of an IND which must take effect before clinical trials may begin;
approval by an independent institutional review board, or IRB, representing each clinical site before clinical testing may be initiated at
the clinical site;
performance of adequate and well-controlled clinical trials in accordance with good clinical practice, or GCP, regulations to establish
the safety and efficacy of the proposed drug product for each indication;
preparation and submission to the FDA of an NDA;
review of the NDA by a FDA advisory committee, if applicable;
satisfactory completion of one or more FDA inspections of the manufacturing facility or facilities at which the product or its
components are produced to assess compliance with current good manufacturing practices, or cGMP, and regulations to assure that the
facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity;
payment of user fees and securing FDA approval of the NDA; and
compliance with any post-approval requirements, including potential requirements for a risk evaluation and mitigation strategy and
post-approval studies required by the FDA.

Once  a  drug  candidate  is  identified  for  development,  it  enters  the  preclinical  or  nonclinical  testing  stage.  Preclinical  studies  include
laboratory evaluations of product chemistry, pharmacology, toxicity and formulation. An IND sponsor must submit the results of the preclinical
studies, together with manufacturing information and analytical data, to the FDA as part of the IND. Some preclinical studies may continue even
after the IND is submitted. In addition to including

12

 
 
 
 
 
 
 
 
Table of Contents

the results of the preclinical studies, the IND will also include a protocol detailing, among other things, the objectives of the clinical trial, the
parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the first phase lends itself to an efficacy determination.
The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, places the IND on
clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin. A clinical hold
may occur at any time during the life of an IND, and may affect one or more specific clinical trials or all clinical trials conducted under the IND.

All  clinical  trials  must  be  conducted  under  the  supervision  of  one  or  more  qualified  investigators  in  accordance  with  current  GCP
regulations.  They  must  be  conducted  under  protocols  detailing  the  objectives  of  the  trial,  dosing  procedures,  research  subject  selection  and
exclusion criteria and the safety and effectiveness criteria to be evaluated. Each protocol must be submitted to the FDA as part of the IND, and
progress reports detailing the status of the clinical trials must be submitted to the FDA annually. Sponsors also must timely report to FDA serious
and  unexpected  adverse  reactions,  any  clinically  important  increase  in  the  rate  of  a  serious  suspected  adverse  reaction  over  that  listed  in  the
protocol  or  investigator  brochure,  or  any  findings  from  other  studies  or  animal  or  in  vitro  testing  that  suggest  a  significant  risk  in  humans
exposed to the drug. An IRB at each institution participating in the clinical trial must review and approve the protocol before the clinical trial
commences  at  that  institution  and  must  also  approve  the  information  regarding  the  trial  and  the  consent  form  that  must  be  provided  to  each
research subject or the subject’s legal representative, monitor the study until completed and otherwise comply with IRB regulations.

Clinical trials are typically conducted in three sequential phases that may overlap or be combined:

·

·

·

Phase 1.  The drug is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism,
distribution and elimination. In the case of some products for severe or life-threatening diseases, such as cancer, and especially when the
product may be inherently too toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients
who already have the condition.
Phase 2.  Clinical trials are performed on a limited patient population intended to identify possible adverse effects and safety risks, to
preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.
Phase 3.  If a drug candidate is found to be potentially effective and to have an acceptable safety profile in Phase 2 clinical trials, the
clinical trial program will be expanded to Phase 3 clinical trials to further evaluate dosage, clinical efficacy and safety in an expanded
patient population at geographically dispersed clinical trial sites. These studies are intended to establish the overall risk-benefit ratio of
the product and provide an adequate basis for product approval and labeling claims.

Phase  4  clinical  trials  are  conducted  after  approval  to  gain  additional  experience  from  the  treatment  of  patients  in  the  intended
therapeutic indication and to document a clinical benefit in the case of drugs approved under accelerated approval regulations, or when otherwise
requested by the FDA in the form of post-market requirements or commitments. Failure to promptly conduct any required Phase 4 clinical trials
could result in withdrawal of approval.

Clinical trials are inherently uncertain, and Phase 1, Phase 2 and Phase 3 testing may not be successfully completed. The FDA or the
sponsor  may  suspend  a  clinical  trial  at  any  time  for  a  variety  of  reasons,  including  a  finding  that  the  research  subjects  or  patients  are  being
exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial
is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. In
some cases, clinical trials are overseen by an independent group of qualified experts organized by the trial sponsor, which is called the clinical
monitoring board or data safety monitoring board. This group provides authorization for whether or not a trial may move forward at designated
check points. These decisions are based on the limited access to data from the ongoing trial.

During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be
prior  to  the  submission  of  an  IND,  at  the  end-of-Phase  2  and  before  an  NDA  is  submitted.  Meetings  at  other  times  may  be  requested.  These
meetings can provide an opportunity for the sponsor to share information about the data gathered to date and for the FDA to provide advice on
the next phase of development. Sponsors typically use the meeting at the end-of-Phase 2 to discuss their Phase 2 clinical trial results and present
their plans for the pivotal Phase 3 clinical trial or trials that they believe will support the approval of the new drug.

13

 
 
 
 
 
 
 
Table of Contents

Concurrent with clinical trials, sponsors usually complete additional animal safety studies and also develop additional information about
the  chemistry  and  physical  characteristics  of  the  drug  and  finalize  a  process  for  manufacturing  commercial  quantities  of  the  product  in
accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug and the
manufacturer must develop methods for testing the quality, purity and potency of the drug. Additionally, appropriate packaging must be selected
and tested, and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its
proposed shelf-life.

The  results  of  product  development,  preclinical  studies  and  clinical  trials,  along  with  descriptions  of  the  manufacturing  process,
analytical tests and other control mechanisms, proposed labeling and other relevant information are submitted to the FDA as part of an NDA
requesting approval to market the product. The submission of an NDA is subject to the payment of user fees, but a waiver of such fees may be
obtained  under  specified  circumstances.  The  FDA  reviews  all  NDAs  submitted  for  a  period  of  60  days  to  ensure  that  they  are  sufficiently
complete for substantive review before it accepts them for filing. It may request additional information rather than accept an NDA for filing. In
this event, the NDA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA
accepts it for filing.

During the approval process, the FDA also will determine whether a risk evaluation and mitigation strategy, or REMS, is necessary to
assure the safe use of the product. If the FDA concludes a REMS is needed, the sponsor of the application must submit a proposed REMS, and
the  FDA  will  not  approve  the  application  without  an  approved  REMS,  if  required.  A  REMS  can  substantially  increase  the  costs  of  obtaining
approval. The FDA could also require a special warning, known as a boxed warning, to be included in the product label in order to highlight a
particular safety risk.

Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA reviews an NDA to determine, among other
things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant. The FDA may refer the
NDA to an advisory committee for review and recommendation as to whether the application should be approved and under what conditions.
The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. NDAs receive either
standard or priority review. A drug representing a significant improvement in treatment, prevention or diagnosis of disease may receive priority
review. A priority review designation is intended to direct overall attention and resources to the evaluation of such applications, and to shorten
the FDA’s goal for taking action on the NDA from ten months to six months from FDA filing of the NDA. After the FDA evaluates the NDA and
conducts  inspections  of  manufacturing  facilities  where  the  drug  product  and/or  its  API  will  be  produced,  it  may  issue  an  approval  letter  or  a
Complete  Response  Letter.  An  approval  letter  authorizes  commercial  marketing  of  the  drug  with  specific  prescribing  information  for  specific
indications.  A  Complete  Response  Letter  indicates  that  the  review  cycle  of  the  application  is  complete,  and  the  application  is  not  ready  for
approval.  A  Complete  Response  Letter  may  require  additional  clinical  data  and/or  an  additional  pivotal  Phase  3  clinical  trial(s),  and/or  other
significant,  expensive  and  time-consuming  requirements  related  to  clinical  trials,  preclinical  studies  or  manufacturing.  Even  if  such  data  and
information are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval.

Post-approval Requirements

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA and other
governmental  agencies,  including,  among  other  things,  requirements  relating  to  recordkeeping,  periodic  reporting,  product  sampling  and
distribution,  advertising  and  promotion  and  reporting  of  adverse  experiences  with  the  product.  Once  an  approval  is  granted,  the  FDA  may
withdraw the approval if compliance with regulatory requirements is not maintained or if problems occur after the product reaches the market.
Later discovery of previously unknown problems with a product may result in restrictions on the product or even complete withdrawal of the
product from the market. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes
and  additional  labeling  claims,  are  subject  to  further  FDA  review  and  approval.  There  also  are  continuing,  annual  user  fee  requirements  for
products and the establishments at which such products are manufactured, as well as new application fees for certain supplemental applications.
In addition, the FDA may require testing and surveillance programs to monitor the effect of approved products that have been commercialized,
and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs.

Drug  manufacturers  and  other  entities  involved  in  the  manufacture  and  distribution  of  approved  drugs  are  required  to  register  their

establishments with the FDA and certain state agencies, and are subject to periodic unannounced

14

 
 
 
 
 
 
Table of Contents

inspections  by  the  FDA  and  some  state  agencies  for  compliance  with  GMP  regulations  and  other  laws.  The  FDA  has  promulgated  specific
requirements for drug cGMPs and device cGMPs embodied in the Quality System Regulation. Changes to the manufacturing process are strictly
regulated  and  often  require  prior  FDA  approval  before  being  implemented.  FDA  regulations  also  require  investigation  and  correction  of  any
deviations from cGMP requirements and impose reporting and documentation requirements upon the sponsor and any third-party manufacturers
that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and
quality control to maintain cGMP compliance.

Failure to comply with the applicable U.S. requirements at any time during the product development process or approval process, or
after approval, may subject us to administrative or judicial sanctions, any of which could have a material adverse effect on us. These sanctions
could include:

·
·
·
·
·
·
·
·

refusal to approve pending applications;
withdrawal of an approval;
imposition of a clinical hold;
warning letters;
product seizures or detention, or refusal to permit the import or export of products;
restrictions on the marketing or manufacturing of the product;
total or partial suspension of production or distribution or product recalls; or
injunctions, fines, disgorgement, or civil or criminal penalties.

The FDA strictly regulates the marketing, labeling, advertising and promotion of drug products that are placed on the market. Drugs
may be promoted only for the approved indications and in accordance with the provisions of the approved label.  However, companies may share
truthful  and  not  misleading  information  that  is  otherwise  consistent  with  the  product’s  FDA  approved  labeling.  The  FDA  and  other  agencies
actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted
off-label  uses  may  be  subject  to  significant  liability.    However,  physicians  may,  in  their  independent  medical  judgment,  prescribe  legally
available  products  for  off-label  uses.  The  FDA  does  not  regulate  the  behavior  of  physicians  in  their  choice  of  treatments  but  the  FDA  does
restrict manufacturer’s communications on the subject of off-label use of their products.

From  time  to  time,  legislation  is  drafted,  introduced  and  passed  in  Congress  that  could  significantly  change  the  statutory  provisions
governing the approval, manufacturing and marketing of products regulated by the FDA. In addition, FDA regulations and guidance are often
issued  revised  or  reinterpreted  by  the  agency  in  ways  that  may  significantly  affect  our  business  and  our  drug  candidates.  It  is  impossible  to
predict whether legislative changes will be enacted, or whether FDA regulations, guidance or interpretations will be issued or changed or what
the impact of such changes, if any, may be.

Non-patent Exclusivity

The  FDCA  provides  a  five-year  period  of  non-patent  marketing  exclusivity  within  the  United  States  to  the  first  applicant  to  obtain
approval  of  an  NDA  for  a  new  chemical  entity,  or  NCE.  A  drug  is  an  NCE  if  the  FDA  has  not  previously  approved  any  other  new  drug
containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance.  If market exclusivity is granted
for an NCE, during the exclusivity period, the FDA may not accept for review or approve an abbreviated new drug application, or ANDA, or a
505(b)(2)  NDA  submitted  by  another  company  for  another  version  of  such  drug  where  the  applicant  does  not  own  or  have  a  legal  right  of
reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent
invalidity or non-infringement to one of the patents listed with the FDA by the innovator NDA holder.

The  FDCA  also  provides  three  years  of  marketing  exclusivity  for  an  NDA,  or  supplement  to  an  existing  NDA  if  new  clinical
investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the
approval of the application, for example new indications, dosages, dosage forms or strengths of an existing drug.  This three-year exclusivity
covers only the conditions associated with the new clinical investigations and prohibits the FDA from approving an ANDA, or a 505(b)(2) NDA
submitted by another company with overlapping conditions associated with the new clinical investigations for the three-year period.  Clinical
investigation exclusivity does not prohibit the FDA from approving ANDAs for drugs containing the original active agent. Five-year and three-
year exclusivity will not delay the submission or approval of an NDA for the same drug. However, an applicant

15

 
 
 
 
 
 
 
Table of Contents

submitting an NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled
clinical trials necessary to demonstrate safety and effectiveness.

Regulation Outside of the United States

Even if we obtain FDA approval for a drug candidate, we must obtain approval by the comparable regulatory authorities of countries
outside of the United States before we can commence clinical trials in such countries, and our potential third-party partners must obtain approval
of the regulators of such countries or economic areas, such as the European Union, before they may market any of our drug candidates in those
countries or areas. The approval process and requirements governing the conduct of clinical trials, product licensing and promotion, pricing and
reimbursement vary greatly by geographic region, and the time may be longer or shorter than that required for FDA approval.

In the European Economic Area, or EEA, which is composed of the 28 Member States of the European Union plus Norway, Iceland and

Liechtenstein, medicinal products can only be commercialized after obtaining a Marketing Authorization, or MA.

There are two types of MAs:

·

·

The  Community  MA,  which  is  issued  by  the  European  Commission  through  the  Centralized  Procedure,  based  on  the  opinion  of  the
Committee  for  Medicinal  Products  for  Human  Use,  or  CHMP,  of  the  European  Medicines  Agency,  or  EMA,  and  which  is  valid
throughout the entire territory of the EEA. The Centralized Procedure is mandatory for certain types of products, such as biotechnology
medicinal products, orphan medicinal products, and medicinal products indicated for the treatment of AIDS, cancer, neurodegenerative
disorders,  diabetes,  auto-immune  and  viral  diseases.  The  Centralized  Procedure  is  optional  for  products  containing  a  new  active
substance not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or
which  are  in  the  interest  of  public  health  in  the  European  Union.  Under  the  Centralized  Procedure,  the  maximum  timeframe  for  the
evaluation of a marketing authorization application is 210 days (excluding clock stops, when additional written or oral information is to
be provided by the applicant in response to questions asked by the CHMP). Accelerated evaluation might be granted by the CHMP in
exceptional cases, when the authorization of a medicinal product is of major interest from the point of view of public health and, in
particular,  from  the  viewpoint  of  therapeutic  innovation.  Under  the  accelerated  procedure,  the  standard  210  days  review  period  is
reduced to 150 days.
National MAs, which are issued by the competent authorities of the Member States of the EEA and only cover their respective territory,
are  available  for  products  not  falling  within  the  mandatory  scope  of  the  Centralized  Procedure.  Where  a  product  has  already  been
authorized  for  marketing  in  a  Member  State  of  the  EEA,  this  National  MA  can  be  recognized  in  another  Member  State  through  the
Mutual Recognition Procedure. If the product has not received a National MA in any Member State at the time of application, it can be
approved simultaneously in various Member States through the Decentralized Procedure.

In  the  EEA,  upon  receiving  marketing  authorization,  new  chemical  entities  generally  receive  eight  years  of  data  exclusivity  and  an
additional  two  years  of  market  exclusivity.  If  granted,  data  exclusivity  prevents  regulatory  authorities  in  the  EEA  from  referencing  the
innovator’s data to assess a generic application. During the additional two-year period of market exclusivity, a generic marketing authorization
can  be  submitted,  and  the  innovator’s  data  may  be  referenced,  but  no  generic  product  can  be  marketed  until  the  expiration  of  the  market
exclusivity. However, there is no guarantee that a product will be considered by the EEA’s regulatory authorities to be a new chemical entity, and
products may not qualify for data exclusivity.

Other Health Care Laws

Health  care  providers,  physicians  and  third-party  payors  in  the  United  States  and  elsewhere  will  play  a  primary  role  in  the
recommendation and prescription of any of our drug candidates for  which  marketing  approval  is  obtained.  Our  potential  third-party  partners’
arrangements with third-party payors, health care professionals and customers may expose them to broadly applicable fraud and abuse and other
health care laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal civil False Claims Act, that may
constrain the business or financial arrangements and relationships through which they sell, market and distribute any drug candidates for which
marketing approval is obtained. In addition, we and our potential third-party partners may be subject to transparency laws and patient

16

 
 
 
 
 
 
 
 
Table of Contents

privacy regulation by the federal government and by the U.S. states and foreign jurisdictions in which we or they conduct business.

The federal Anti-Kickback Statute makes it illegal for any person or entity, including a prescription drug manufacturer (or a party acting
on  its  behalf)  to  knowingly  and  willfully,  directly  or  indirectly,  solicit,  receive,  offer,  or  pay  any  remuneration  that  is  intended  to  induce  the
referral of business, including the purchase, order, or lease of any good, facility, item or service for which payment may be made under a federal
health  care  program,  such  as  Medicare  or  Medicaid.  The  term  "remuneration"  has  been  broadly  interpreted  to  include  anything  of  value.  The
Anti-Kickback  Statute  has  been  interpreted  to  apply  to  arrangements  between  pharmaceutical  manufacturers  on  one  hand  and  prescribers,
purchasers, formulary managers, and beneficiaries on the other. Although there are a number of statutory exceptions and regulatory safe harbors
protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration
that may be alleged to be intended to induce prescribing, purchases or recommendations 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 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 its facts and circumstances. Several courts have interpreted the statute’s intent requirement to mean that
if any one purpose of an arrangement involving remuneration is to induce referrals of federal health care covered business, the Anti-Kickback
Statute has been violated. Violations of this law are punishable by up to five years in prison, and can also result in criminal fines, civil monetary
penalties, administrative penalties and exclusion from participation in federal health care programs.

Additionally, the intent standard under the Anti-Kickback Statute was amended by the Patient Protection and Affordable Care Act of
2010, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the Affordable Care Act, to a stricter standard
such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a
violation. In addition, the Affordable Care Act codified case law that a claim including items or services resulting from a violation of the federal
Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.

Federal false claims and false statement laws, including the federal civil False Claims Act, prohibits, among other things, any person or
entity  from  knowingly  presenting,  or  causing  to  be  presented,  for  payment  to,  or  approval  by,  federal  programs,  including  Medicare  and
Medicaid, claims for items or services, including drugs, that are false or fraudulent or not provided as claimed. Entities can be held liable under
these  laws  if  they  are  deemed  to  "cause"  the  submission  of  false  or  fraudulent  claims  by,  for  example,  providing  inaccurate  billing  or  coding
information to customers, promoting a product off-label, or for providing medically unnecessary services or items. In addition, activities relating
to  the  sale  and  marketing  of  products  are  subject  to  scrutiny  under  this  law.  Penalties  for  the  federal  civil  False  Claims  Act  violations  may
include  up  to  three  times  the  actual  damages  sustained  by  the  government,  plus  mandatory  civil  penalties  for  each  separate  false  claim,  the
potential for exclusion from participation in federal health care programs, and, although the federal civil False Claims Act is a civil statute, False
Claims  Act  violations  may  also  implicate  various  federal  criminal  statutes.    For  example,  the  federal  Health  Insurance  Portability  and
Accountability Act of 1996, or HIPAA, created federal criminal statutes that prohibit among other actions, knowingly and willfully executing, or
attempting  to  execute,  a  scheme  to  defraud  any  health  care  benefit  program,  including  private  third-party  payors,  knowingly  and  willfully
embezzling or stealing from a health care benefit program, willfully obstructing a criminal investigation of a health care offense, and knowingly
and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection
with the delivery of or payment for health care benefits, items or services. Like the Anti-Kickback Statute, the Affordable Care Act amended the
intent standard for the health care fraud statute under HIPAA such that a person or entity no longer needs to have actual knowledge of the statute
or specific intent to violate it in order to have committed a violation.

The  civil  monetary  penalties  statute  imposes  penalties  against  any  person  or  entity  that,  among  other  things,  is  determined  to  have
presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was
not provided as claimed or is false or fraudulent.

Also, many states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payor,
in  addition  to  items  and  services  reimbursed  under  Medicaid  and  other  state  programs.  Additionally,  to  the  extent  that  a  product  is  sold  in  a
foreign country, the seller may be subject to similar foreign laws.

In  addition,  legislation  imposing  marketing  restrictions  and  transparency  requirements  on  pharmaceutical  manufacturers  has  been

enacted at the state and federal levels.  For example, the Affordable Care Act imposed, among

17

 
 
 
 
 
 
Table of Contents

other things, annual reporting requirements for covered manufacturers for certain payments and other transfers of value provided to physicians,
as  defined  by  such  law,  and  teaching  hospitals,  as  well  as  ownership  and  investment  interests  held  by  physicians  and  their  immediate  family
members.  Failure  to  submit  timely,  accurately  and  completely  the  required  information  for  all  payments,  transfers  of  value  and  ownership  or
investment interests may result in civil monetary penalties for "knowing failures."  Certain states also mandate implementation of compliance
programs,  impose  restrictions  on  drug  manufacturer  marketing  practices,  require  registration  of  certain  employees  engaged  in  marketing
activities in the location, and/or require the tracking and reporting of gifts, compensation and other remuneration to physicians. 

We  have  developed  a  comprehensive  compliance  program  that  establishes  internal  controls  to  facilitate  adherence  to  the  rules  and
program  requirements  to  which  we  are  subject.  Although  the  development  and  implementation  of  compliance  programs  designed  to  establish
internal controls and facilitate compliance can mitigate the risk of investigation, prosecution, and penalties assessed for violations of these laws,
or any other laws that may apply to us, the risks cannot be entirely eliminated. If our operations are found to be in violation of any of such laws
or  any  other  governmental  regulations,  we  may  be  subject  to  significant  penalties,  including,  without  limitation,  administrative,  civil,  and
criminal penalties, damages, fines, disgorgement, imprisonment, contractual damages, reputational harm, diminished profits and future earnings,
the  curtailment  or  restructuring  of  our  operations,  exclusion  from  participation  in  federal  and  state  health  care  programs,  additional reporting
requirements  and  oversight  if  we  become  subject  to  a  corporate  integrity  agreement  or  similar  agreement  to  resolve  allegations  of  non-
compliance  with  these  laws  and  individual  imprisonment,  any  of  which  could  adversely  affect  our  ability  to  operate  our  business  and  our
financial results.

We may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct our
business. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their implementing
regulations, including the final omnibus rule published on January 25, 2013, mandates, among other things, the adoption of uniform standards for
the  electronic  exchange  of  information  in  common  health  care  transactions,  as  well  as  standards  relating  to  the  privacy  and  security  of
individually  identifiable  health  information,  which  require  the  adoption  of  administrative,  physical  and  technical  safeguards  to  protect  such
information. Among other things, HITECH makes HIPAA’s security standards directly applicable to "business associates", namely independent
contractors or agents of HIPAA covered entities that create, receive or obtain protected health information in connection with providing a service
for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities and
business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the
federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, certain state laws govern the
privacy and security of health information in certain circumstances, some of which are more stringent than HIPAA and many of which differ
from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws,
where applicable, can result in the imposition of significant civil and/or criminal penalties.

Health Care Reform

In the United States, there have been and continue to be a number of significant legislative initiatives to contain health care costs. For
example, in March 2010, the Affordable Care Act was passed, which has had, and is expected to continue to have, a significant impact on the
health care industry. The Affordable Care Act was designed to expand coverage for the uninsured and at the same time containing overall health
care costs. With regard to pharmaceutical products, among other things, the Affordable Care Act expanded and increased industry rebates for
drugs  covered  under  Medicaid  programs;  addressed  a  new  methodology  by  which  rebates  owed  by  manufacturers  under  the  Medicaid  Drug
Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected; extended the rebate program to individuals
enrolled  in  Medicaid  managed  care  organizations;  established  annual  fees  and  taxes  on  manufacturers  of  certain  branded  prescription  drugs;
made changes to the coverage requirements under the Medicare prescription drug benefit; and established a new Medicare Part D coverage gap
discount program, in which manufacturers, as a condition for their outpatient drugs to be covered under Medicare Part D,  must agree to offer
70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period.  Moreover,
the  Affordable  Care  Act  provided  incentives  to  programs  that  increase  the  federal  government’s  comparative  effectiveness  research  and
implemented  payment  system  reforms  including  a  national  pilot  program  on  payment  bundling  meant  to  encourage  hospitals,  physicians  and
other providers to improve the coordination, quality and efficiency of certain health care services.

There  remain  judicial  and  Congressional  challenges  to,  as  well  as  efforts  by  the  Trump  Administration  to  repeal  or  replace  certain
aspects of the Affordable Care Act.  For example, since January 2017, President Trump has signed two executive orders and other directives
designed  to  delay,  circumvent,  or  loosen  certain  requirements  mandated  by  the  Affordable  Care  Act.  Concurrently,  Congress  has  considered
legislation that would repeal or repeal and replace all or part of the Affordable Care Act. While Congress has not passed comprehensive repeal
legislation, two bills affecting the implementation of certain taxes under the Affordable Care Act have been signed into law.  The Tax Cuts and
Jobs  Act  of  2017  includes  a  provision  repealing,  effective  January  1,  2019,  the  tax-based  shared  responsibility  payment  imposed  by  the
Affordable Care Act 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”.  In addition, the 2020 federal spending package permanently eliminates, effective January 1, 2020, the Affordable
Care Act-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also
eliminates the health insurer tax.  Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amended the Affordable Care
Act, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”.  In December
2018, the Centers for Medicare & Medicaid Services, or CMS, published a new final rule permitting further collections and payments to and
from certain Affordable Care Act qualified health plans and health insurance issuers under the Affordable Care Act risk adjustment program in
response to the outcome of federal district court litigation regarding the method CMS uses to determine this risk adjustment. On December 14,
2018, a Texas U.S. District Court Judge ruled that the Affordable Care Act is unconstitutional in its entirety because the “individual mandate”
was repealed by Congress as part of the Tax Cuts and Jobs Act of 2017. Additionally, on December 18, 2019, the U.S. Court of Appeals for the
5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to
determine  whether  the  remaining  provisions  of  the  Affordable  Care  Act  are  invalid  as  well. It  is  unclear  how  this  decision,  future  decisions,
subsequent appeals, and other efforts to repeal and replace the Affordable Care Act will impact the Affordable Care Act.

In  addition,  other  legislative  changes  have  been  proposed  and  adopted  since  the  Affordable  Care  Act  was  enacted.  For  example,  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  in  spending  reductions.  The  Joint  Select  Committee  on  Deficit  Reduction  did  not
achieve a targeted deficit reduction of at least $1.2 trillion for fiscal years 2012 through 2021, triggering the legislation’s automatic reduction to
several  government  programs.  This  includes  aggregate  reductions  in  Medicare  payments  to  providers  of  2%  per  fiscal  year,  which  went  into
effect beginning on April 1, 2013 and, due to subsequent legislative amendments to the statute, including the BBA, will stay in effect through
2029, unless additional Congressional action is taken. Additionally, in January 2013, the American Taxpayer Relief Act of 2012 was signed into
law,  which,  among  other  things,  reduced  Medicare  payments  to  several  providers,  including  hospitals,  cancer  treatment  centers  and  imaging
centers. Moreover, the Drug Supply Chain Security Act imposes new obligations on manufacturers of pharmaceutical products related to product
tracking  and  tracing.  Legislative  and  regulatory  proposals  have  been  made  to  expand  post-approval  requirements  and  restrict  sales  and
promotional activities for pharmaceutical products.

More recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed
products. 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.  At the federal level, the Trump Administration’s budget proposal for
fiscal  year  2020  contains  further  drug  price  control  measures  that  could  be  enacted  during  the  budget  process  or  in  other  future  legislation,
including, for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some
states  to  negotiate  drug  prices  under  Medicaid,  and  to  eliminate  cost  sharing  for  generic  drugs  for  low-income  patients.  Further,  the  Trump
Administration released a “Blueprint”, or plan, 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  health  care  programs,  incentivize  manufacturers  to
lower  the  list  price  of  their  products,  and  reduce  the  out-of-pocket  costs  of  drug  products  paid  by  consumers.  The  Department  of  Health  and
Human  Services,  or  HHS,  has  solicited  feedback  on  some  of  these  measures  and  has  implemented  others  under  its  existing  authority.  For
example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning
January 1, 2020. This final rule codified CMS’ policy change that was effective January 1, 2019. While some of these and other measures may
require additional authorization to become effective, Congress and the Trump Administration have both stated that they will continue to seek
new legislative and/or administrative measures to control drug costs. At the state level, legislatures have become increasingly active in passing
legislation  and  implementing  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient
reimbursement

19

 
 
Table of Contents

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.

The  Affordable  Care  Act,  as  well  as  other  federal  and  state  health  care  reform  measures  that  have  been  and  may  be  adopted  in  the
future, could harm our future revenue.  Additional legislative actions may be taken in the future which may change current regulations, guidance
and interpretations.  The impact of such actions on our business, if any, cannot presently be determined.

The Hatch Waxman Amendments to the FDC Act

Orange Book Listing

In  seeking  approval  for  a  drug  through  an  NDA,  applicants  are  required  to  list  with  the  FDA  each  patent  whose  claims  cover  the
applicant’s product or a method of using the 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  competitors  in  support  of  approval  of  an  ANDA  or  an  application  covered  by  Section
505(b)(2) of the FDCA. An ANDA provides for marketing of a drug product that has the same active ingredients, generally in the same strengths
and dosage form, as the listed drug and has been shown through pharmacokinetic, or PK, testing to be bioequivalent to the listed drug. 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.  Other  than  the  requirement  for  bioequivalence  testing,  ANDA  applicants  are  generally  not
required to conduct, or submit results of, preclinical studies or clinical tests to prove the safety or effectiveness of their drug product. Section
505(b)(2) applications provide for marketing of a drug product that may have the same active ingredients as the listed drug and contains full
safety and effectiveness data as an NDA, but at least some of this information comes from studies not conducted by or for the applicant. This
alternate  regulatory  pathway  enables  the  applicant  to  rely,  in  part,  on  the  FDA’s  findings  of  safety  and  efficacy  for  an  existing  product,  or
published literature, in support of its application. The FDA may then approve the new drug candidate for all or some of the labeled indications
for which the referenced product has been approved, as well as for any new indication sought by the 505(b)(2) applicant.

The ANDA or Section 505(b)(2) 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: (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  or  Section  505(b)(2)  applicant  may  also  elect  to  submit  a
statement certifying that its proposed ANDA label does not contain, or carves out, any language regarding a patented method of use rather than
certify to such listed method of use patent. If the applicant does not challenge the listed patents by filing a certification that the listed patent is
invalid or will not be infringed by the new product, the ANDA or Section 505(b)(2) 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, is
called  a  Paragraph  IV  certification.  If  the  ANDA  or  Section  505(b)(2)  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 or Section 505(b)(2) application
has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of
the  Paragraph  IV  certification.  The  filing  of  a  patent  infringement  lawsuit  within  45  days  of  the  receipt  of  a  Paragraph  IV  certification
automatically prevents the FDA from approving the ANDA or Section 505(b)(2) application until the earliest of 30 months, expiration of the
patent,  settlement  of  the  lawsuit,  and  a  decision  in  the  infringement  case  that  is  favorable  to  the  ANDA  or  Section  505(b)(2)  applicant.  This
prohibition is generally referred to as the 30-month stay. Thus, approval of an ANDA or 505(b)(2) NDA could be delayed for a significant period
of time depending on the patent certification the applicant makes and the reference drug sponsor’s decision to initiate patent litigation.

The ANDA or Section 505(b)(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange

Book for the referenced product has expired.

Patent Term Extension

In  the  United  States,  after  NDA  approval,  owners  of  relevant  drug  patents  may  apply  for  up  to  a  five  year  patent  extension,  which
provides  patent  term  restoration  as  compensation  for  the  patent  term  lost  during  the  FDA  regulatory  review  process  for  the  first  permitted
commercial  marketing  of  a  drug  product.  The  Drug  Price  Competition  and  Patent  Term  Restoration  Act  of  1984,  or  the  Hatch-Waxman  Act,
permits a patent term extension of up to five years beyond the expiration of the patent. The allowable patent term extension is calculated as half
of the drug’s testing phase, which is the time between the IND submission becoming effective and the NDA submission, and all of the review
phase, which is the time between NDA submission and approval, up to a maximum extension of five years. The time can be shortened if the
FDA determines that the applicant did not pursue approval with due diligence. Patent extension cannot extend the remaining term of a patent
beyond a total of 14 years from the date of product approval and only one patent applicable to an approved drug may be extended. 

Similar  provisions  are  available  in  the  European  Union  and  other  foreign  jurisdictions  to  extend  the  term  of  a  patent  that  covers  an
approved drug. For example, in Japan, it may be possible to extend the patent term for up to five years and in the European Union, it may be
possible to obtain a supplementary patent certificate that would effectively extend patent protection for up to five years.

Coverage and Reimbursement

We  believe  the  success  of  our  drug  candidates,  if  approved,  will  depend  on  obtaining  and  maintaining  coverage  and  adequate
reimbursement as a prescription treatment or in the absence of coverage and adequate reimbursement, on the extent to which patients will be
willing to pay out of pocket for our prescription drug products.

Third-party payors determine which prescription drug products they will cover and establish reimbursement levels. Reimbursement by a
third-party payor may depend upon a number of factors, including: the third-party payor’s determination that a product is safe, effective, and
medically necessary; appropriate for the specific patient; cost-effective; supported by peer-reviewed medical journals or current clinical practice
guidelines; and whether there are competitive products, either branded or generic, and the pricing of those products.  Many private third-party
payors,  such  as  managed  care  plans,  manage  access  to  drug  products’  coverage  partly  to  control  costs  for  their  plans,  and  may  use  drug
formularies  and  medical  policies  to  limit  their  exposure.    Obtaining  and  maintaining  favorable  reimbursement  can  be  a  time-consuming  and
expensive process, and our potential third-party partners may not be able to negotiate or continue to negotiate reimbursement or pricing terms for
our drug candidates, if approved, with third-party payors at levels that are profitable to us, or at all.   

In addition to uncertainties surrounding coverage policies, there are periodic changes to reimbursement.  Third-party payors regularly
update reimbursement amounts and also from time to time revise the methodologies used to determine reimbursement amounts.  Accordingly,
these  updates  could  impact  the  demand  for  our  drug  candidates,  if  approved.  Our  drug  candidates,  if  approved,  may  not  be  considered  cost
effective, and government and third-party private health insurance coverage and reimbursement may not be available to patients or sufficient to
allow our potential third-party partners to sell our drug candidates, if approved, on a competitive and profitable basis.  Our results of operations
could  be  adversely  affected  by  the  Affordable  Care  Act  and  by  other  health  care  reforms  that  may  be  enacted  or  adopted  in  the  future.    In
addition, increasing emphasis on managed care in the United States will continue to put pressure on the pricing of pharmaceutical products.  Cost
control initiatives could decrease the price that our potential third-party partners could receive for any of our drug candidates, if approved, and
could  adversely  affect  our  profitability.    We  cannot  predict  how  pending  and  future  health  care  legislation  will  impact  our  business,  and  any
changes in coverage and reimbursement that further restricts coverage of our drug candidates could harm our business.  

Foreign governments also have their own health care reimbursement systems, which vary significantly by country and region, and we
cannot be sure that coverage and adequate reimbursement will be made available with respect to our drug candidates, if approved, under any
foreign reimbursement system.  In some foreign countries, including major markets in the European Union and Japan, the pricing of prescription
pharmaceuticals  is  subject  to  governmental  control.    In  these  countries,  pricing  negotiations  with  governmental  authorities  can  take  up  to  12
months  or  longer  after  the  receipt  of  regulatory  marketing  approval  for  a  product.    To  obtain  reimbursement  or  pricing  approval  in  some
countries,  we  may  be  required  to  conduct  a  pharmacoeconomic  study  that  compares  the  cost-effectiveness  of  our  drug  candidate  to  other
available therapies.  Such pharmacoeconomic studies can be costly and the results uncertain.  Our business could be

21

 
 
 
 
 
 
 
Table of Contents

harmed if reimbursement of our drug candidates, if approved, is unavailable or limited in scope or amount or if pricing is set at unsatisfactory
levels.

Item 1A. Risk Factors

Our business is subject to numerous risks. You should carefully consider the following risks and all other information contained in this
Annual Report, as well as general economic and business risks, together with any other documents we file with the SEC. If any of the following
events  actually  occur  or  risks  actually  materialize,  it  could  have  a  material  adverse  effect  on  our  business,  operating  results  and  financial
condition and cause the trading price of our common stock to decline.

Risks Related to Our Business, Our Financial Position and Capital Needs

We have incurred significant losses since our inception. We expect to incur losses over the next several years and may never achieve

or maintain profitability.

We have a limited operating history. Since inception, we have incurred significant net losses. We incurred net losses of $161.4 million
and $132.7 million for the years ended December 31, 2019 and 2018, respectively. As of December 31, 2019, we had an accumulated deficit of
$453.5  million.  We  have  financed  our  operations  over  the  last  several  years  primarily  from  public  offerings  and  a  private  placement  of  our
common stock, as well as debt financing that has since been repaid in full.  We have one commercial product, ESKATA, that we are no longer
distributing,  marketing  or  selling,  one  late-stage  investigational  drug  candidate  and  other  preclinical  and  clinical  drug  candidates  that  we  are
developing.

We have devoted substantially all of our financial resources and efforts to the development of our drug candidates, including preclinical
studies and clinical trials, and from 2018 to October 2019, to the commercialization of our products. Our net losses may fluctuate significantly
from quarter to quarter and year to year. We expect to continue to incur significant expenses and operating losses in the near term as we:

·

·

pursue  strategic  alternatives,  including  identifying  and  seeking  to  consummate  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize our drug candidates and ESKATA;
continue the clinical development of ATI-450, our MK2 inhibitor, as a potential treatment for rheumatoid arthritis and potentially
an additional immuno-inflammatory indication;
continue to develop our preclinical drug candidates, including ATI-1777, a soft-JAK inhibitor, and ATI-2138, an ITJ inhibitor;
seek to discover and develop additional drug candidates;

·
·
· maintain, expand and protect our intellectual property portfolio; and
·

incur legal, accounting, investor relations and other administrative expenses in operating as a public company.  

To  become  and  remain  profitable,  we  must  succeed  in  a  range  of  challenging  activities,  including  completing  preclinical  testing  and
clinical trials of our drug candidates and pursuing strategic alternatives, including identifying and consummating transactions with third-party
partners, for the further development and/or commercialization of our drug candidates, as well as discovering and developing additional drug
candidates. We are in the early stages of most of these activities. We may never succeed in these activities and, even if we do, may never earn
revenue from our drug candidates that is significant enough to achieve profitability.

For any of our drug candidates, our revenue will be dependent, in part, upon our ability to identify and consummate transactions with
third-party partners to further develop, obtain marketing approval for and/or commercialize those drug candidates. Further, we will be dependent
on  our  potential  third-party  partners’  ability  to  obtain  marketing  approval  and  successfully  commercialize  the  product,  upon  the  size  of  the
markets  in  the  territories  where  marketing  approval  is  obtained,  the  accepted  price  for  the  product,  and  the  ability  to  obtain  coverage  and
reimbursement, if any. If we fail to identify and enter into partnerships with third parties to further develop, obtain marketing approval for and/or
commercialize  our  drug  candidates,  any  partnerships  we  enter  into  do  not  result  in  the  successful  development,  marketing  approval  for  and
commercialization  of  our  drug  candidates,  the  number  of  addressable  patients  is  not  as  significant  as  estimated  by  our  potential  third-party
partners, the indication approved by regulatory authorities is narrower than expected, or the treatment population is narrowed by competition,
physician choice or treatment guidelines, we may not earn significant revenue from agreements with potential third-party partners for such drug
candidates, even if the drug candidates are approved for marketing. 

23

Because of the numerous risks and uncertainties associated with drug development, we are unable to accurately predict the timing or
amount  of  expenses  or  when,  or  if,  we  will  be  able  to  achieve  profitability.  If  we  are  required  by  regulatory  authorities  to  perform  studies  in
addition to those expected, or if there are any delays in the initiation and completion of our clinical trials, the development of any of our drug
candidates  or  the  identification  and  consummation  of  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for
and/or commercialize our drug candidates, our expenses could increase.

Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to
become  and  remain  profitable  would  depress  the  value  of  our  company  and  could  impair  our  ability  to  raise  capital,  expand  our  business,
maintain our development efforts, diversify our offerings or continue our operations. A decline in the value of our company could also cause you
to lose all or part of your investment.

We will need substantial additional funding to meet our financial obligations and to pursue our business objectives. If we are unable

to raise capital when needed, we could be forced to curtail our planned operations. 

Identifying potential drug candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain
process that takes years to complete, and we may never generate the necessary data or results required to identify and consummate transactions
with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates.  We  expect  to  incur
significant expenses and operating losses for the foreseeable future as we advance our drug candidates from discovery through preclinical and
clinical  development.  In  addition,  we  may  not  be  able  to  identify  and  consummate  transactions  with  third-party  partners  to  further  develop,
obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates,  and  our  drug  candidates,  if  approved,  may  not  achieve  commercial
success.    Furthermore,  we  have  incurred  and  expect  to  continue  to  incur  significant  costs  associated  with  operating  as  a  public  company,
including legal, accounting, investor relations and other expenses. 

As of December 31, 2019, we had cash, cash equivalents and marketable securities of $75.0 million. We believe that our existing cash,
cash  equivalents  and  marketable  securities  as  of  the  date  of  this  Annual  Report  will  enable  us  to  fund  our  operating  expenses  and  capital
expenditure  requirements  for  a  period  greater  than  12  months  from  the  date  of  this  report  based  on  our  current  operating  assumptions.  These
assumptions may prove to be wrong, and we could use our available capital resources sooner than we expect. Changes may occur beyond our
control that would cause us to consume our available capital before that time, including changes in and progress of our development activities,
acquisitions of additional products or drug candidates, and changes in regulation. Our future capital requirements will depend on many factors,
including:

·
·

·
·
·

·

·

the number and development requirements of the drug candidates that we may pursue;
the scope, progress, results and costs of preclinical development, laboratory testing and conducting preclinical and clinical trials for
our drug candidates;
the costs, timing and outcome of regulatory review of our drug candidates;
the extent to which we in-license or acquire additional drug candidates and technologies;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property
rights and defending any intellectual property-related claims;
our  ability  to  identify  and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for
and/or commercialize our drug candidates, and earn revenue from such arrangements; and
the revenue earned from our commercial products as a result of licenses to, or partnerships with, third parties.

We  expect  that  we  will  require  additional  capital  to  complete  the  clinical  development  of  ATI-450,  to  develop  our  preclinical
compounds and to support our discovery efforts.  Additional funds may not be available on a timely basis, on commercially acceptable terms, or
at all, and such funds, if raised, may not be sufficient to enable us to continue to implement our long-term business strategy. If we are unable to
raise sufficient additional capital, we could be forced to curtail our planned operations.

24

 
 
 
 
 
 
 
 
Table of Contents

Our business is dependent on the successful development of our drug candidate, ATI-450.

Our  pipeline  includes  ATI-450,  our  investigational  oral,  novel,  selective  MK2  inhibitor  compound,  which  we  are  developing  for
rheumatoid arthritis and potentially for an additional immuno-inflammatory indication. We expect to initiate a Phase 2a clinical trial for ATI-450
in  subjects  with  rheumatoid  arthritis  in  the  first  half  of  2020.    The  success  of  our  business  will  significantly  depend  on  our  successful
development of and/or our ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners,
to further develop, obtain marketing approval for and/or commercialize ATI-450.

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

technologies, intellectual property, potential future revenue streams or drug candidates.

Until  such  time,  if  ever,  as  we  can  earn  substantial  revenue,  we  expect  to  finance  our  cash  needs  through  a  combination  of  equity
offerings,  debt  financings  and  license  and  partnership  agreements.  To  the  extent  that  we  raise  additional  capital  through  the  sale  of  equity
securities or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other
preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve
agreements  that  include  covenants  limiting  or  restricting  our  ability  to  take  specific  actions,  such  as  incurring  additional  debt,  making  capital
expenditures or declaring dividends.

If  we  raise  additional  funds  through  partnerships,  strategic  alliances  or  marketing,  distribution  or  licensing  arrangements  with  third-
party partners, we may be required to relinquish valuable rights to our technologies, intellectual property, potential future revenue streams, or
drug  candidates  or  grant  licenses  on  terms  that  may  not  be  favorable  to  us.  If  we  are  unable  to  raise  additional  funds  through  equity  or  debt
financings or other arrangements with third parties when needed, we may be required to delay, limit, reduce or terminate our drug development
efforts or grant rights to third parties to develop technologies, intellectual property, or drug candidates that we would otherwise prefer to develop
ourselves.

We  have  a  limited  operating  history  and  recently  changed  our  strategic  focus  to  focus  on  the  development  of  our  immuno-

inflammatory portfolio, which may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

Our operations over the last several years have been largely focused on raising capital, undertaking preclinical studies and conducting
clinical  trials,  and  acquiring  new  drug  candidates  and  related  intellectual  property.  In  2018  and  2019,  we  were  also  focused  on  the
commercialization  of  two  commercial  products.  In  September  2019,  we  announced  the  completion  of  a  strategic  review  of  our  business,  as  a
result  of  which  we  are  refocusing  our  resources  on  our  immuno-inflammatory  development  programs  and  are  pursuing  strategic  alternatives,
including  seeking  partners,  for  our  investigational  drug  candidates  and  ESKATA.  We  have  had  limited  time  to  demonstrate  our  ability  to
successfully  develop,  manufacture  and  identify  and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain  marketing
approval for and/or commercialize our drug candidates. Consequently, any predictions you make about our future success or viability may not be
as accurate as they could be if we had a longer operating history or a longer history of developing and partnering drugs. We may also encounter
unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business objectives.

Our  business  and  operations  would  suffer  in  the  event  of  computer  system  failures,  cyber-attacks  or  a  deficiency  in  our  cyber-

security.

Despite  the  implementation  of  security  measures,  our  internal  computer  systems,  and  those  of  third  parties  on  which  we  rely,  are
vulnerable to damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks
or  cyber-intrusions  over  the  Internet,  attachments  to  emails,  persons  inside  our  organization,  or  persons  with  access  to  systems  inside  our
organization. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusion, including by computer hackers,
foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions
from  around  the  world  have  increased.  If  such  an  event  were  to  occur  and  cause  interruptions  in  our  operations,  it  could  result  in  a  material
disruption of our drug development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials
could result in delays in obtaining marketing approval for our drug candidates and significantly increase our costs to recover or reproduce the
data.  To  the  extent  that  any  disruption  or  security  breach  was  to  result  in  a  loss  of  or  damage  to  our  data  or  applications,  or  inappropriate
disclosure of confidential or proprietary

25

 
 
 
 
 
 
 
 
Table of Contents

information, we could incur material legal claims and liability, damage to our reputation, and the further development or commercialization of
our drug candidates by a potential third-party partner could be delayed.

Risks Related to the Development and Potential Commercialization of Our Drug Candidates

If  we  are  unable  to  successfully  develop  our  drug  candidates  and  to  pursue  strategic  alternatives,  including  identifying  and
consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug
candidates, or experience significant delays in doing so, our business will be harmed.

We have invested significant efforts and financial resources in the development of our drug candidates and the identification of potential
drug candidates. Our ability to earn substantial revenue from our drug candidates will depend heavily on our ability to successfully develop and
pursue strategic alternatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing
approval for and/or commercialize these drug candidates. The success of any drug candidates that we develop, including A-101 45% Topical
Solution and ATI-450, will depend on several factors, including:

·
·
·
·

·
·

·

·
·

·

successful completion of preclinical studies and our clinical trials;
successful development of manufacturing processes for any of our drug candidates that receive marketing approval;
receipt of timely approvals from applicable regulatory authorities;
the  identification  and  consummation  of  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for
and/or commercialize our drug candidates;
the commercial launch of our drug candidates by a third-party partner, if approved;
our third-party partners’ ability to achieve acceptance of our drug candidates, if approved, by patients, the medical community and
third-party payors, and willingness of patients to pay out of pocket for our drug candidates when third-party payor coverage and
reimbursement is limited or unavailable;
our third-party partners’ ability to achieve success in educating physicians and patients about the benefits, administration and use of
our drug candidates, if approved;
the prevalence and severity of adverse events experienced with our drug candidates;
the availability, perceived advantages, cost, safety and efficacy of alternative treatments for the proposed indications of our drug
candidates;
obtaining  and  maintaining  patent,  trademark  and  trade  secret  protection  and  regulatory  exclusivity  for  our  drug  candidates  and
otherwise protecting the intellectual property portfolio;

· maintaining compliance with regulatory requirements, including current good manufacturing practices, or cGMPs;
·
·

our third-party partners’ ability to compete effectively with other treatment procedures; and
our third-party partners’ ability to maintain a continued acceptable safety, tolerability and efficacy profile of our drug candidates
following marketing approval.

Whether marketing approval will be granted is unpredictable and depends upon numerous factors, including the substantial discretion of
the  regulatory  authorities.  Our  drug  candidates’  success  in  clinical  trials  will  not  guarantee  marketing  approval.  If,  following  submission,  the
NDA for any drug candidate is not accepted for substantive review, or even if it is accepted for substantive review, the FDA or other comparable
foreign regulatory authorities may require additional studies or clinical trials, additional data, or additional manufacturing steps, or require other
conditions  before  they  will  reconsider  or  approve  the  application.  If  the  FDA  or  other  comparable  foreign  regulatory  authorities  require
additional studies, clinical trials or data, this could increase costs and cause delays in the marketing approval process, which may require the
expenditure of additional resources. These delays would also impact our ability to identify and consummate transactions with third-party partners
to further develop, obtain marketing approval for and/or commercialize our drug candidates. In addition, the FDA or other comparable foreign
regulatory  authorities  may  not  consider  sufficient  any  additional  required  studies,  clinical  trials,  data  or  information  that  we  perform  and
complete or generate, or we may decide to abandon the program.

It is possible that our drug candidates currently in development will never obtain marketing approval. If we do not achieve one or more
of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully pursue strategic alternatives,
including identifying and consummating transactions with third-party

26

 
 
 
 
 
 
Table of Contents

partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates, which would harm our business.

Clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or
experience  delays  in  completing,  or  ultimately  be  unable  to  complete,  the  development  of  and  pursue  strategic  alternatives,  including
identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize
our drug candidates.

The risk of failure for our drug candidates is high. It is impossible to predict when or if any of our drug candidates will prove effective
or safe in humans or will receive marketing approval. Before obtaining regulatory approval for the sale of any drug candidate, we must complete
preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of our drug candidates in humans for use
in  the  target  indication.  Clinical  testing  is  expensive,  difficult  to  design  and  implement,  can  take  many  years  to  complete  and  is  inherently
uncertain as to outcome.

A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may
not  be  predictive  of  the  success  of  later  clinical  trials,  and  interim  results  of  a  clinical  trial  do  not  necessarily  predict  final  results.  Moreover,
preclinical  and  clinical  data  are  often  susceptible  to  varying  interpretations  and  analyses,  and  many  companies  that  have  believed  their  drug
candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their drugs.

We may experience numerous unforeseen events during or as a result of clinical trials that could delay or prevent our ability to pursue
strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our drug candidates, including:

·

·

·

·

·

·

·

·
·

regulators or institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a clinical
trial at a prospective trial site;
we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols
with prospective trial sites or prospective contract research organizations, or CROs, the terms of which can be subject to extensive
negotiation and may vary significantly among different CROs and trial sites;
clinical  trials  of  our  drug  candidates  may  produce  negative  or  inconclusive  results,  including  failure  to  demonstrate  statistical
significance, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon drug development
programs;
the  number  of  patients  required  for  clinical  trials  of  our  drug  candidates  may  be  larger  than  we  anticipate,  enrollment  in  these
clinical  trials  may  be  slower  than  we  anticipate,  or  participants  may  drop  out  of  these  clinical  trials  or  fail  to  return  for  post-
treatment follow-up at a higher rate than we anticipate;
our  drug  candidates  may  have  undesirable  side  effects  or  other  unexpected  characteristics,  causing  us  or  our  investigators,
regulators or institutional review boards to suspend or terminate the trials;
our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely
manner, or at all;
regulators  or  institutional  review  boards  may  require  that  we  or  our  investigators  suspend  or  terminate  clinical  development  for
various  reasons,  including  noncompliance  with  regulatory  requirements  or  a  finding  that  the  participants  are  being  exposed  to
unacceptable health risks;
the cost of clinical trials of our drug candidates may be greater than we anticipate; and
the supply or quality of our drug candidates or other materials necessary to conduct clinical trials of our drug candidates may be
insufficient or inadequate.

We could also encounter delays if a clinical trial is suspended or terminated by us, by the institutional review boards of the institutions
in which such trials are being conducted, by the data safety monitoring board for such trial or by the FDA or other regulatory authorities. Such
authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance
with  regulatory  requirements  or  our  clinical  protocols,  inspection  of  the  clinical  trial  operations  or  trial  site  by  the  FDA  or  other  regulatory
authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from
using  a  drug,  changes  in  governmental  regulations  or  administrative  actions  or  lack  of  adequate  funding  to  continue  the  clinical  trial.    If  we
experience delays in the completion of, or termination of, any clinical trial of our drug candidates, our costs will increase, our drug candidate
development process will be slowed, the commercial prospects of our drug candidates

will be harmed, and our ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners, to
further develop, obtain marketing approval for and/or commercialize our drug candidates will be delayed. Any of these occurrences may harm
our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement
or completion of clinical trials may also ultimately lead to the denial of marketing approval of our drug candidates. If we are required to conduct
additional  clinical  trials  or  other  testing  of  our  drug  candidates  beyond  those  that  we  currently  contemplate,  if  we  are  unable  to  successfully
complete clinical trials of our drug candidates or other testing, if the results of these trials or tests are not favorable or if there are safety concerns,
we  may  not  be  able  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize our drug candidates, and our potential third-party partners may:

·
·
·
·
·
·

be delayed in obtaining marketing approval for our drug candidates;
not obtain marketing approval at all;
obtain marketing approval for indications or patient populations that are not as broad as intended or desired;
obtain marketing approval with labeling that includes significant use or distribution restrictions or safety warnings;
be subject to additional post-marketing testing requirements; or
have the drug removed from the market after obtaining marketing approval.

Our drug development costs will also increase if we experience delays in testing. We do not know whether any of our preclinical studies
or clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant preclinical study or
clinical trial delays also could shorten any periods during which our potential third-party partners may have the exclusive right to commercialize
our  drug  candidates  or  allow  competitors  to  bring  drugs  to  market  before  such  third-party  partners  do,  which  would  impact  our  ability  to
successfully  identify  and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize our drug candidates.

If  we  experience  delays  or  difficulties  in  the  enrollment  of  subjects  in  clinical  trials,  our  ability  to  pursue  strategic  alternatives,
including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or
commercialize our drug candidates could be delayed or prevented.

Successful  and  timely  completion  of  clinical  trials  will  require  that  we  enroll  a  sufficient  number  of  subjects.  Subject  enrollment,  a
significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population. Trials may be
subject to delays as a result of subject enrollment taking longer than anticipated or subject withdrawal. We may not be able to initiate or continue
clinical trials for our drug candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as
required by the FDA or similar regulatory authorities outside the United States. We cannot predict how successful we will be at enrolling subjects
in future clinical trials. Subject enrollment is affected by other factors including:

·
·
·
·
·
·
·

the eligibility criteria for the trial in question;
the perceived risks and benefits of the drug candidate in the trial;
the availability of drugs approved to treat the skin disease in the trial;
the efforts to facilitate timely enrollment in clinical trials;
the patient referral practices of physicians;
the ability to monitor patients adequately during and after treatment; and
the proximity and availability of clinical trial sites for prospective patients.

Our inability to enroll a sufficient number of subjects for clinical trials would result in significant delays and could require us or them to
abandon one or more clinical trials altogether. Enrollment delays in these clinical trials may result in increased development costs for our drug
candidates, which would cause the value of our company to decline and limit our ability to obtain additional financing. Furthermore, we rely on
and expect to continue to rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and we will have
limited  influence  over  their  performance.  Any  delays  in  completing  clinical  trials  would  delay  or  prevent  our  ability  to  pursue  strategic
alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for
and/or commercialize our drug candidates.

28

Our clinical trials may fail to demonstrate the safety and efficacy of our drug candidates, or serious adverse or unacceptable side
effects  may  be  identified  during  the  development  of  our  drug  candidates,  which  could  prevent  or  delay  our  ability  to  pursue  strategic
alternatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval
for and/or commercialize our drug candidates, increase our costs or necessitate the abandonment or limitation of the development of some of
our drug candidates.

Before  any  potential  third-party  partners  can  obtain  marketing  approvals  for  the  commercial  sale  of  our  drug  candidates,  we  must
demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that our drug candidates are both safe and effective for
use in each target indication, and failures can occur at any stage of testing. Clinical trials often fail to demonstrate safety and efficacy of the drug
candidate studied for the target indication.

If  our  drug  candidates  are  associated  with  side  effects  in  clinical  trials  or  have  characteristics  that  are  unexpected,  we  may  need  to
abandon their development or limit development to more narrow uses in which the side effects or other characteristics are less prevalent, less
severe  or  more  acceptable  from  a  risk-benefit  perspective.  The  FDA  or  an  institutional  review  board  may  also  require  that  we  suspend,
discontinue, or limit our clinical trials based on safety information. Such findings could further result in regulatory authorities failing to provide
marketing authorization for our drug candidates. Many drug candidates that initially showed promise in early stage testing have later been found
to cause side effects that prevented further development of the drug candidate.

Additionally,  if  we  or  others  identify  undesirable  side  effects  caused  by  our  drugs,  a  number  of  potentially  significant  negative

consequences could result, including:

·
·
·
·
·
·

regulatory authorities may withdraw approval to market such product;
regulatory authorities may require additional warnings on the labels;
a medication guide outlining the risks of such side effects for distribution to patients may be required;
we could be sued and held liable for harm caused to patients;
our reputation and physician or patient acceptance of our drug candidates, if approved, may suffer; and
our ability to pursue strategic alternatives, including identifying and consummating transactions with third-party partners, to further
develop, obtain marketing approval for and/or commercialize our drug candidates would be harmed.

Any  of  these  events  could  prevent  us  from  pursuing  strategic  alternatives,  including  identifying  and  consummating  transactions  with
third-party partners, to further develop, obtain marketing approval for and/or commercialize the particular drug candidate and could significantly
harm our business, results of operations and prospects.

Changes in methods of drug candidate manufacturing or formulation may result in additional costs or delay.

As drug candidates are developed through preclinical studies to late-stage clinical trials towards approval and commercialization, it is
common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort
to  optimize  processes  and  results.  Such  changes  carry  the  risk  that  they  will  not  achieve  these  intended  objectives,  and  may  also  require
additional testing, FDA notification or FDA approval.  Any of these changes could cause our drug candidates to perform differently and affect
the results of planned clinical trials or other future clinical trials conducted with the altered materials.  This could delay completion of clinical
trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of
our drug candidates and jeopardize our ability to pursue strategic alternatives, including identifying and consummating transactions with third-
party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates.

We may not be successful in our efforts to increase our pipeline of drug candidates, including by in-licensing or acquiring additional

drug candidates.

A key element of our strategy is to build and expand our pipeline of drug candidates. To build our pipeline, we may seek to in-license or
acquire additional drug candidates. We may not be able to identify or develop drug candidates that are safe, tolerable and effective. Even if we
are successful in continuing to build our pipeline, the potential drug candidates that we identify, in-license or acquire may not be suitable for
clinical development, including as a result of being shown to have harmful side effects or other characteristics that indicate that they are unlikely
to be drugs that will receive marketing approval and achieve market acceptance.

We may expend our limited resources to pursue a particular drug candidate or indication and fail to capitalize on drug candidates or

indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and management resources, we focus on development programs and drug candidates that we identify
for  specific  indications.  As  such,  we  are  currently  primarily  focused  on  the  development  of  ATI-450  as  a  potential  treatment  for  rheumatoid
arthritis  and  an  additional  immuno-inflammatory  indication.    As  a  result,  we  may  forego  or  delay  pursuit  of  opportunities  with  other  drug
candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to
capitalize on viable commercial drugs or profitable market opportunities. Our spending on current and future development programs and drug
candidates for specific indications may not yield any commercially viable drugs. If we do not accurately evaluate the commercial potential or
target market for a particular drug candidate, we may relinquish valuable rights to that drug candidate through partnerships, licensing or other
royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to
such drug candidate.

For any of our drug candidates that receive marketing approval, our third-party partners may fail to achieve the degree of market

acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

For any of our drug candidates that receive marketing approval, our third-party partners may fail to gain sufficient market acceptance by
physicians,  patients,  third-party  payors  and  others  in  the  medical  community.  If  our  third-party  partners  fail  to  obtain  an  adequate  level  of
acceptance for our drug candidates, we may not earn significant revenue and we may not become profitable. The degree of market acceptance of
any drug candidate, if approved, will depend on a number of factors, including:

·
·
·
·
·
·
·
·
·

the efficacy, safety and potential advantages compared to alternative treatments;
our third-party partners’ ability to offer the products for sale at competitive prices;
the convenience and ease of administration compared to alternative treatments;
the willingness of the target patient population to try new treatments and of physicians to prescribe these treatments;
the ability of our potential third-party partners to retain a sales force;
the strength of our potential third-party partners’ marketing and distribution support;
the availability of third-party payor coverage and adequate reimbursement or the willingness of patients to pay for these products;
the prevalence and severity of any side effects; and
any restrictions on the use of our products together with other medications.

We  face  substantial  competition,  which  may  result  in  others  discovering,  developing  or  commercializing  drugs  before  or  more

successfully than we do.

The  development  and  commercialization  of  new  drugs  is  highly  competitive.  We  will  face  competition  with  respect  to  any  drug
candidates that we may seek to develop or through our potential third-party partners, commercialize, in the future, from many different sources,
including major pharmaceutical, biotechnology and specialty pharmaceutical companies, academic institutions and governmental agencies and
public and private research institutions.

With respect to A-101 45% Topical Solution for the treatment of common warts, we are aware of at least two other companies that are
developing a drug candidate for the treatment of common warts. In addition, there are over-the-counter drugs for the treatment of common warts
and other drugs that have been used off-label as treatments for common warts. 

With respect to ATI-450 as a potential treatment for rheumatoid arthritis, there are numerous commercial products, such as anti-TNFs,
anti-IL6s, anti-IL1s and JAK inhibitors, approved for the treatment of rheumatoid arthritis. In addition, we are aware of a number of companies
conducting late-stage clinical trials for investigational drug candidates for the treatment of rheumatoid arthritis.

The  commercial  opportunity  for  our  drug  candidates,  if  approved,  could  be  reduced  or  eliminated  if  our  competitors  develop  and
commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than a drug
that  we  may  develop.  Our  competitors  also  may  obtain  FDA  or  other  regulatory  approval  for  their  drugs  more  rapidly  than  our  third-party
partners’ may obtain approval for our drug candidates, which could result in our competitors establishing a strong market position before our
drug candidates are able to enter the market.

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

The  success  of  our  drug  candidates,  if  approved,  will  depend  significantly  on  coverage  and  adequate  reimbursement  or  the

willingness of patients to pay for these products.

We  believe  the  success  of  our  drug  candidates,  if  approved,  will  depend  on  obtaining  and  maintaining  coverage  and  adequate
reimbursement as a prescription treatment or in the absence of coverage and adequate reimbursement, on the extent to which patients will be
willing to pay out of pocket for our prescription drug products.

Third-party payors determine which prescription drug products they will cover and establish reimbursement levels. Reimbursement by a
third-party payor may depend upon a number of factors, including: the third-party payor’s determination that a product is safe, effective, and
medically necessary; appropriate for the specific patient; cost-effective; supported by peer-reviewed medical journals or current clinical practice
guidelines; and whether there are competitive products, either branded or generic, and the pricing of those products.  Many private third-party
payors,  such  as  managed  care  plans,  manage  access  to  drug  products’  coverage  partly  to  control  costs  for  their  plans,  and  may  use  drug
formularies  and  medical  policies  to  limit  their  exposure.    Obtaining  and  maintaining  favorable  reimbursement  can  be  a  time-consuming  and
expensive process, and our potential third-party partners may not be able to negotiate or continue to negotiate reimbursement or pricing terms for
our products with third-party payors at levels that are profitable to us, or at all.  

In addition to uncertainties surrounding coverage policies, there are periodic changes to reimbursement.  Third-party payors regularly
update reimbursement amounts and also from time to time revise the methodologies used to determine reimbursement amounts.  Accordingly,
these  updates  could  impact  the  demand  for  our  drug  candidates,  if  approved.  Our  drug  candidates,  if  approved,  may  not  be  considered  cost
effective, and government and third-party private health insurance coverage and reimbursement may not be available to patients or sufficient to
allow our potential third-party partners to sell our drug candidates, if approved, on a competitive and profitable basis.  Our results of operations
could  be  adversely  affected  by  the  Affordable  Care  Act  and  by  other  health  care  legislative  reforms  that  may  be  enacted  or  adopted  in  the
future.  In addition, increasing emphasis on managed care in the United States will continue to put pressure on the pricing of pharmaceutical
products.  Cost control initiatives could decrease the price that our potential third-party partners could receive for any of our drug candidates, if
approved,  and  could  adversely  affect  our  profitability.    We  cannot  predict  how  pending  and  future  health  care  legislation  will  impact  our
business, and any changes in coverage and reimbursement that further restricts coverage of our drug candidates could harm our business.

Foreign governments also have their own healthcare reimbursement systems, which vary significantly by country and region, and we
cannot be sure that coverage and adequate reimbursement will be made available with respect to our drug candidates, if approved, under any
foreign reimbursement system.  In some foreign countries, including major markets in the European Union and Japan, the pricing of prescription
pharmaceuticals  is  subject  to  governmental  control.    In  these  countries,  pricing  negotiations  with  governmental  authorities  can  take  up  to  12
months  or  longer  after  the  receipt  of  regulatory  marketing  approval  for  a  product.    To  obtain  reimbursement  or  pricing  approval  in  some
countries,  we  may  be  required  to  conduct  a  pharmacoeconomic  study  that  compares  the  cost-effectiveness  of  our  drug  candidate  to  other
available therapies.  Such pharmacoeconomic studies can be costly and the results uncertain.  Our business could be harmed if reimbursement of
our drug candidates, if approved, is unavailable or limited in scope or amount or if pricing is set at unsatisfactory levels.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any of our drug
candidates  that  we  may  develop  and  are  commercialized  by  our  potential  third-party  partners  or  impact  any  commercial  products  that  we
have previously sold or are being sold by third-party partners.

We face an inherent risk of product liability exposure related to the testing of our drug candidates in human clinical trials and an even
greater  risk  relating  to  any  of  our  commercial  products  that  we  have  previously  sold  or  are  being  sold  by  third-party  partners.  If  we  cannot
successfully defend ourselves against claims that our commercial products that we have previously sold or are being sold by third-party partners
or drug candidates caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may
result in:

·
·
·
·
·
·
·
·

decreased demand for any drug candidates that we may develop and are commercialized by our potential third-party partners;
injury to our reputation and significant negative media attention;
withdrawal of clinical trial participants;
significant costs to defend the related litigation;
substantial monetary awards paid to trial participants or patients;
loss of revenue;
reduced resources of our management to pursue our business strategy; and
our  inability  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to
further develop, obtain marketing approval for and/or commercialize our drug candidates.

We currently hold $10 million in product liability insurance coverage in the aggregate, with a per incident limit of $10 million, which
may  not  be  adequate  to  cover  all  liabilities  that  we  may  incur.  Insurance  coverage  is  increasingly  expensive.  We  may  need  to  increase  our
insurance coverage and we may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability
that may arise.

Risks Related to Our Dependence on Third Parties

We  rely  on  third  parties  to  conduct  clinical  trials  for  our  drug  candidates,  and  those  third  parties  may  not  perform  satisfactorily,

including failing to meet deadlines for the completion of such trials.

We engage CROs to conduct clinical trials of our drug candidates. We expect to continue to rely on third parties, such as clinical data
management organizations, medical institutions and clinical investigators, to conduct those clinical trials. If any of our relationships with these
third parties terminate, we may not be able to timely enter into arrangements with alternative third parties or to do so on commercially reasonable
terms, if at all. In addition, any third parties conducting our clinical trials will not be our employees, and except for remedies available to us
under  our  agreements  with  such  third  parties,  we  cannot  control  whether  or  not  they  devote  sufficient  time  and  resources  to  our  clinical
programs. If these third parties 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,  our  clinical  trials  may  be  extended,  delayed  or  terminated  and  we  may  not  be  able  to  identify
and    consummate  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug
candidates.  Consequently,  our  results  of  operations  and  the  commercial  prospects  for  our  drug  candidates  would  be  harmed,  our  costs  could
increase substantially and our ability to earn revenue from those partnerships could be delayed significantly.

Switching or adding CROs involves substantial cost and requires management time and focus. In addition, there is a natural transition
period  when  a  new  CRO  commences  work.  As  a  result,  delays  occur,  which  can  materially  impact  our  ability  to  meet  our  desired  clinical
development  timelines.  Though  we  intend  to  carefully  manage  our  relationships  with  our  CROs,  there  can  be  no  assurance  that  we  will  not
encounter challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial
condition and prospects.

We  rely  on  these  parties  for  execution  of  our  preclinical  studies  and  clinical  trials,  and  generally  do  not  control  their  activities.  Our
reliance on these third parties for research and development activities will reduce our control over these activities but will not relieve us of our
responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general
investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with standards, commonly referred to as good clinical
practices, or GCPs, for

32

 
 
 
 
 
 
 
 
Table of Contents

conducting,  recording  and  reporting  the  results  of  clinical  trials  to  assure  that  data  and  reported  results  are  credible  and  accurate  and  that  the
rights, integrity and confidentiality of trial participants are protected. We also are required to register ongoing clinical trials and post the results of
completed  clinical  trials  on  a  government-sponsored  database,  ClinicalTrials.gov,  within  specified  timeframes.  Failure  to  do  so  can  result  in
fines,  adverse  publicity  and  civil  and  criminal  sanctions.  If  we  or  any  of  our  CROs  fail  to  comply  with  applicable  GCPs,  the  clinical  data
generated in our clinical trials may be deemed unreliable and the FDA, European Medicines Agency or comparable foreign regulatory authorities
may  require  us  to  perform  additional  clinical  trials  before  approving  marketing  applications.  We  cannot  assure  you  that  upon  inspection  by  a
given regulatory authority, such regulatory authority will determine that any of our clinical trials complies with GCP regulations. In addition, our
clinical trials must be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to
repeat clinical trials, which would delay the marketing approval process for our potential third-party partners.

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

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

We do not have any manufacturing facilities. We currently rely, and expect to continue to rely, on third parties for the manufacture and
supply  of  our  drug  candidates  for  preclinical  and  clinical  testing.    For  example,  we  have  entered  into  an  exclusive,  ten-year,  automatically
renewable  supply  agreement  with  PeroxyChem,  a  manufacturer  of  hydrogen  peroxide,  to  provide  the  active  pharmaceutical  ingredient  that  is
used in A-101 45% Topical Solution for the potential treatment of common warts. This reliance on third parties increases the risk that we will not
have sufficient quantities of our drug candidates at an acceptable cost and/or quality, which could delay, prevent or impair our ability to timely
conduct our clinical trials or our other development efforts.

The facilities used by our contract manufacturers to manufacture our drug candidates must be approved by the FDA or other regulatory
authorities pursuant to inspections that will be conducted after the NDA or comparable marketing application is submitted to the FDA or other
regulatory  authority.  We  do  not  have  control  over  a  supplier’s  or  manufacturer’s  compliance  with  laws,  regulations  and  applicable  cGMP
standards and other laws and regulations, such as those related to environmental health and safety matters. If our contract manufacturers cannot
successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not
be  able  to  secure  and  maintain  regulatory  approval  for  their  manufacturing  facilities.  In  addition,  we  have  no  control  over  the  ability  of  our
contract  manufacturers  to  maintain  adequate  quality  control,  quality  assurance  and  qualified  personnel.  If  the  FDA  or  a  comparable  foreign
regulatory  authority  does  not  approve  these  facilities  for  the  manufacture  of  our  drug  candidates  or  if  it  withdraws  any  such  approval  in  the
future,  we  may  need  to  find  alternative  manufacturing  facilities,  which  could  significantly  impact  our  ability  to  develop,  and  identify  and
consummate transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize, our drug candidates.

We may be unable to establish any agreements with future third-party manufacturers or to do so on acceptable terms. Even if we are

able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:

·
·
·
·
·

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

Third-party  manufacturers  may  not  be  able  to  comply  with  cGMP  regulations  or  similar  regulatory  requirements  outside  the  United
States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed
on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension

33

 
 
 
 
 
 
 
Table of Contents

or  withdrawal  of  approvals,  license  revocation,  seizures  or  recalls  of  products,  operating  restrictions  and  criminal  prosecutions,  any  of  which
could significantly and adversely affect supplies of our drug candidates. 

Our drug candidates may compete with other products and drug candidates for access to manufacturing facilities. There are a limited
number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. Any performance failure on
the part of our existing or future manufacturers could delay clinical development or marketing approval of our drug candidates.

If our current contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers. We may incur added
costs and delays in identifying and qualifying any such replacement. We do not currently have arrangements in place for redundant supply or a
second source for the active pharmaceutical ingredients and/or drug product for our drug candidates.

We  expect  to  continue  to  depend  on  third-party  contract  manufacturers  for  the  foreseeable  future.  Our  current  and  anticipated  future
dependence  upon  others  for  the  manufacture  of  our  drug  candidates  may  adversely  affect  our  future  profit  margins  and  our  ability  to  pursue
strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing
approval for and/or commercialize our drug candidates on a timely and competitive basis.

We intend to pursue strategic alternatives, including identifying and consummating transactions with third-party partners, to further
develop, obtain marketing approval for and/or commercialize our drug candidates. If those arrangements are not successful, we may not be
able to capitalize on the market potential of these drug candidates.

We  intend  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop, obtain marketing approval for and/or commercialize our drug candidates. For example, we intend to seek a partner to obtain marketing
approval  and  commercialize  A-101  45%  Topical  Solution  as  a  potential  treatment  for  common  warts  and  a  partner  to  further  develop,  obtain
marketing approval and commercialize ATI-501 and ATI-502 as potential treatments for alopecia. Our likely partners for any such arrangements
include large and mid-size pharmaceutical companies, regional and national pharmaceutical companies and biotechnology companies. If we do
enter into any such arrangements with any third parties, we will likely have limited control over the amount and timing of resources that our
partners  dedicate  to  the  development  or  commercialization  of  our  drug  candidates.  Our  ability  to  earn  revenue  from  these  arrangements  will
depend on our partners’ abilities to successfully perform the functions assigned to them in these arrangements.

Partnerships involving our drug candidates would pose the following risks to us:

·
·
·

·

·

·

·

partners have significant discretion in determining the efforts and resources that they will apply to these arrangements;
partners may not perform their obligations as expected;
partners  may  not  pursue  development,  marketing  approval  or  commercialization  of  any  drug  candidates  that  achieve  marketing
approval or may elect not to continue or renew development or commercialization programs based on clinical trial results, changes
in  the  partners’  strategic  focus  or  available  funding,  or  external  factors,  such  as  an  acquisition,  that  divert  resources  or  create
competing priorities;
partners may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a drug
candidate, repeat or conduct new clinical trials or require a new formulation of a drug candidate for clinical testing;
partners  could  independently  develop,  or  develop  with  third  parties,  products  that  compete  directly  or  indirectly  with  our  drug
candidates if the partners believe that competitive products are more likely to be successfully developed or can be commercialized
under terms that are more economically attractive than ours;
drug candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own products or
drug candidates, which may cause our partners to cease to devote resources to the development and/or commercialization of our
drug candidates, if approved;
a partner with marketing and distribution rights to one or more of our drug candidates that achieve marketing approval may not
commit sufficient resources to the marketing and distribution of such drug candidates;

disagreements  with  partners,  including  disagreements  over  proprietary  rights,  contract  interpretation  or  the  preferred  course  of
development or commercialization, might cause delays or termination of the research, development or commercialization of drug
candidates, might lead to additional responsibilities for us with respect to drug candidates, or might result in litigation or arbitration,
any of which would be time-consuming and expensive;
partners may not properly maintain or defend our or their intellectual property rights or may use our or their proprietary information
in  such  a  way  as  to  invite  litigation  that  could  jeopardize  or  invalidate  such  intellectual  property  or  proprietary  information  or
expose us to potential litigation;
partners may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability; and
partnerships  may  be  terminated  for  the  convenience  of  the  partner  and,  if  terminated,  we  could  be  required  to  raise  additional
capital to pursue further development and/or commercialization of the applicable drug candidates.

Partnership agreements may not lead to development, marketing approval or commercialization of drug candidates in the most efficient
manner or at all. If a present or future partner of ours were to be involved in a business combination, the continued pursuit and emphasis on our
drug development or commercialization program could be delayed, diminished or terminated. 

If we are not able to establish partnerships, we may have to alter our development and commercialization plans.

Our drug development programs for our drug candidates will require substantial additional capital. For some of our drug candidates, we
intend  to  partner  with  pharmaceutical  and  biotechnology  companies  for  the  further  development  and/or  commercialization  of  those  drug
candidates.

We face significant competition in seeking appropriate partners. Whether we reach a definitive agreement for a partnership will depend,
among other things, upon our assessment of the partner’s resources and expertise, the terms and conditions of the proposed arrangement and the
proposed partner’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval
by  the  FDA  or  similar  regulatory  authorities  outside  the  United  States,  the  potential  market  for  the  subject  drug  candidate,  the  costs  and
complexities of manufacturing and delivering such drug 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. The partner may also consider alternative drug candidates or technologies for similar
indications  that  may  be  available  to  partner  on  and  whether  such  a  partnership  could  be  more  attractive  than  the  one  with  us  for  our  drug
candidate. Partnerships 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 partners.

We may not be able to negotiate partnerships 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 such drug candidate, or reduce or delay its development program or one or more of our other development programs,
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 drug candidates or
bring them to market and generate revenue.

We may not have access to all information regarding our drug candidates that are subject to partnership agreements. Consequently,
our ability to inform our stockholders about the status of our drug candidates that are subject to these agreements, and our ability to make
business and operational decisions, may be limited.

We may not have access to all information regarding our drug candidates that may become subject to agreements with partners, including
potentially  material  information  about  clinical  trial  design,  execution  and  timing,  safety  and  efficacy,  clinical  trial  results,  regulatory  affairs,
manufacturing, marketing, sales and other areas known by our potential partners. In addition, we may have confidentiality obligations under our
agreements with such partners. Therefore, our ability to keep our stockholders informed about the status of our drug candidates will be limited by
the degree to which our partners keep us informed and by the degree to which our partners allow us to disclose information to the public or

35

 
 
 
 
 
Table of Contents

provide such information to the public themselves. If our partners do not timely inform us about the status of our drug candidates that are the
subject of the partnership, we may make operational and investment decisions that we would not have made had we been fully informed, which
may have an adverse impact on our business, prospects, financial condition and results of operations.

We are dependent upon EPI Health for the commercialization of RHOFADE, and if we successfully pursue strategic alternatives,
including identifying and consummating transactions with third-party partners, to further develop and/or commercialize our drug candidates
and ESKATA, we will be dependent on the success of such third-party partners.

In October 2019, we sold the worldwide rights to RHOFADE to EPI Health.  Among other payment obligations, EPI Health has agreed
to  pay  us  potential  sales  milestone  payments  of  up  to  $20.0  million  in  the  aggregate  upon  the  achievement  of  specified  levels  of  net  sales,  a
specified  high  single-digit  royalty  calculated  as  a  percentage  of  net  sales,  and  25%  of  any  upfront,  license,  milestone,  maintenance  or  fixed
payment  received  by  EPI  Health  in  connection  with  any  license  or  sublicense  of  the  assets  transferred  in  any  territory  outside  of  the  United
States, subject to specified exceptions.  We also intend to pursue strategic alternatives, including identifying and consummating transactions with
third-party partners, to further develop, obtain regulatory approval and/or commercialize our drug candidates and ESKATA. We cannot control
the timing or quantity of resources that our existing or future potential third-party partners will dedicate to developing and/or commercializing
these products and drug candidates. Our partners may not perform their obligations according to our expectations or standards of quality. Our
partners  could  terminate  our  existing  agreements  for  a  number  of  reasons,  including  that  they  may  have  other,  higher  priority  products  in
development or because our partnered programs may no longer be a priority for them. If any of our partnership agreements were to be terminated
or if any of our partners do not perform as expected, we could lose the opportunity to earn any revenues from the arrangements with such third-
party partners, incur unforeseen costs, and suffer damage to the reputation of the product and as a company generally.

Our sublease could terminate if the master lease is terminated for any reason, thus terminating our rights to our corporate

headquarters.

We sublease space for our corporate headquarters.  While the term of the sublease extends until October 2023, if for any reason the

master lease is terminated or expires prior to October 2023, our sublease will also automatically terminate.  In such an event, we would need to
obtain a new direct lease with the master landlord or negotiate and enter into a new lease for office space at a different location, which we may
not be able to do on commercially reasonable terms, if at all.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain patent protection for our drug candidates, or if the scope of the patent protection obtained is
not  sufficiently  broad,  our  competitors  could  develop  and  commercialize  technology  and  drugs  similar  or  identical  to  ours,  and  ability  to
successfully identify a potential third-party partner to commercialize our technology and drug candidates may be impaired.

Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with
respect to our drug candidates. We seek to protect our proprietary position by filing patent applications in the United States and abroad related to
our drug candidates. 

The patent prosecution process is expensive and time-consuming, however, and we may not be able to file and prosecute all necessary
or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our
development output before it is too late to obtain patent protection. We may not have the right to control the preparation, filing and prosecution
of  patent  applications,  or  to  maintain  the  rights  to  patents  licensed  to  third  parties.  Therefore,  these  patents  and  applications  may  not  be
prosecuted and enforced in a manner consistent with the best interests of our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual
questions and has in recent years been the subject of much litigation. In addition, the laws of foreign countries may not protect our rights to the
same extent as the laws of the United States or vice versa. For example, European patent law restricts the patentability of methods of treatment of
the  human  body  more  than  U.S.  law  does.  Publications  of  discoveries  in  the  scientific  literature  often  lag  behind  the  actual  discoveries,  and
patent applications in the

36

 
 
 
 
 
 
 
 
 
Table of Contents

United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot
know with certainty whether we or our licensors were the first to make the inventions claimed in our patents or pending patent applications, or
that we or our licensors were the first to file for patent protection of such inventions. As a result, the issuance, scope, validity, enforceability and
commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued that
protect  our  technology  or  drug  candidates,  in  whole  or  in  part,  or  which  effectively  prevent  others  from  commercializing  competitive
technologies and drug candidates. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries
may diminish the value of our patents or narrow the scope of our patent protection.

Moreover, we may be subject to a third-party preissuance submission of prior art to the U.S. Patent and Trademark Office, or USPTO,
or become involved in opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our
patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of,
or invalidate, our patent rights, allow third parties to commercialize  our  technology  or  drug  candidates  and  compete  directly  with  us,  without
payment  to  us,  or  result  in  the  inability  of  our  potential  third-party  partners  to  manufacture  or  commercialize  our  drug  candidates  without
infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications that we
own, or license is threatened, it could dissuade companies from partnering with us to license, develop and/or commercialize our drug candidates. 

Even  if  our  patent  applications  that  we  own  or  license  issue  as  patents,  they  may  not  issue  in  a  form  that  will  provide  us  with  any
meaningful protection, prevent competitors from competing with us or our potential third-party partners or otherwise provide us or our potential
third-party partners  with  any  competitive  advantage.  Competitors  may  be  able  to  circumvent  our  patents  by  developing  similar  or  alternative
technologies or drugs in a non-infringing manner.  For example, the patents and patent applications that we exclusively license from Columbia
University  that  are  primarily  directed  to  methods  of  treating  hair  loss  disorders  with  JAK  inhibitors  have  issued  and  may  issue  with  claims
directed to the use of specific JAK inhibitors that we do not intend to develop or commercialize or may not issue with claims directed to the use
of JAK inhibitors that our competitors may commercialize.

In addition, the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our patents may be
challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate
or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit the ability to stop others from using
or commercializing similar or identical technology and drug candidates, or limit the duration of the patent protection of our technology and drug
candidates. Our issued U.S. patents covering our lead inhibitor of the MK2 signaling pathway, ATI-450, expire in 2034 and other issued patents
covering different MK2 signaling pathway inhibitors expire in 2031 and 2032. We currently do not have any patents issued directed to our lead
soft-JAK inhibitor, ATI-1777, but any claims that may issue would expire in 2038. We currently do not have any patents issued directed to our
lead ITK inhibitor, ATI-2138, but any claims that may issue would expire in 2039.  Our issued patents covering other novel inhibitors of ITK
expire between 2035 and 2038. Certain issued U.S. patents relating to our JAK inhibitors, ATI-501 and ATI-502, are scheduled to expire in 2023
and additional U.S. patents, with claims specifically directed to such JAK inhibitors, are scheduled to expire in 2030. The issued U.S., European,
Japanese  and  South  Korean  patents  that  we  exclusively  license  from  Columbia  University  with  claims  directed  to  the  use  of  third-party  JAK
inhibitors for the treatment of hair loss disorders, including AA and AGA, and inducing hair growth, expire in 2031. Our issued U.S. patents,
with claims directed to treatment of SK and acrochordons with high-concentration hydrogen peroxide of at least 23%, including ESKATA, are
scheduled to expire in 2022, and our issued U.S. patents with claims directed to high-concentration hydrogen peroxide formulations, including
A-101 45% Topical Solution and ESKATA, and methods of use and applicators for the same are scheduled to expire in 2035. Given the amount
of  time  required  for  the  development,  testing  and  regulatory  review  of  new  drug  candidates,  patents  protecting  such  candidates  might  expire
before  or  shortly  after  such  candidates  are  commercialized.  As  a  result,  our  patent  portfolio  may  not  provide  us  or  our  potential  third-party
partners with sufficient rights to exclude others from commercializing drugs similar or identical to ours.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time-

consuming and unsuccessful. Further, our issued patents could be found invalid or unenforceable if challenged in court.

Competitors may infringe our issued patents or other intellectual property. Our pending applications cannot be enforced against third

parties practicing the technology claimed in such applications unless and until a patent issues from

37

 
 
 
 
 
Table of Contents

such applications. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and
time-consuming. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that
we infringe their patents or that our patents are invalid or unenforceable. Grounds for a validity challenge could be an alleged failure to meet any
of  several  statutory  requirements,  including  lack  of  novelty,  obviousness,  non-enablement  or  insufficient  written  description.  Grounds  for  an
unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the
USPTO  or  made  a  misleading  statement  during  prosecution.  Third  parties  may  also  raise  similar  claims  before  the  USPTO,  in  post-grant
proceedings  such  as  ex parte  reexaminations,  inter  partes  review,  or  post-grant  review,  or  oppositions  or  similar  administrative  proceedings
outside the United States, in parallel with litigation or, even outside the context of litigation. The outcome following legal assertions of invalidity
and unenforceability is unpredictable. With respect to the validity question, 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 or
unenforceability, we would lose at least part, and perhaps all, of the patent protection on our drug candidates. Such a loss of patent protection
would harm our business. 

In such a proceeding, a court or administrative board may decide that a patent of ours is invalid or unenforceable, in whole or in part,
construe the patent's claims narrowly or refuse to stop the other party from using the technology at issue on the grounds that our patents do not
cover the technology. An adverse result in any such proceeding could put one or more of our patents at risk of being invalidated or interpreted
narrowly. We may find it impractical or undesirable to enforce our intellectual property against some third parties. For instance, we are aware of
third parties that have marketed high-concentration hydrogen peroxide solutions over the internet for the treatment of warts. These parties do not
appear to have regulatory authority, and we have not authorized them in any way to market these products. However, to date we have refrained
from seeking to enforce our intellectual property rights against these third parties due to the transient nature of their activities.  

Interference  proceedings  provoked  by  third  parties  or  brought  by  us  or  declared  by  the  USPTO  may  be  necessary  to  determine  the
priority  of  inventions  with  respect  to  our  patents  or  patent  applications.  An  unfavorable  outcome  could  require  us  to  cease  using  the  related
technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a
license on commercially reasonable terms. 

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk

that some of our confidential information could be compromised by disclosure during this type of litigation.

With  respect  to  ATI-501  and  ATI-502,  if  we  do  not  elect  to  exercise  our  first  right  to  do  so,  Rigel  may  enforce  the  licensed  patents
relating to ATI-501 and ATI-502 against any infringing third party in the field of dermatology. In addition, Rigel has the first right, but not the
obligation, to enforce the licensed patents relating to ATI-501 and ATI-502 against any infringing party outside of the field of dermatology. With
respect to the licensed patents from Columbia University, Columbia University has the first right to initiate, control and defend any proceedings
related  to  the  validity,  enforceability  or  infringement  of  the  licensed  patent  rights  and  in  doing  so,  has  no  obligation  to  assert  more  than  one
licensed patent in one jurisdiction against a third party. With respect to the licensed patents from Columbia University, if Columbia University
does not elect to exercise its first right to do so, we may enforce the licensed patent rights relating to an infringement of the licensed patent rights
against any infringing third party.

If  we  breach  our  license  agreement  with  Rigel,  it  could  compromise  our  ability  to  identify  and  consummate  transactions  with
potential third-party partners to further develop, obtain marketing approval for and commercialize our JAK inhibitors, ATI-501 and ATI-502.

We entered into an exclusive license agreement with Rigel, which grants us the rights to certain patent rights and other intellectual property
owned by them relating to the JAK inhibitors ATI-501 and ATI-502 in the field of dermatology. If we materially breach or fail to perform any
provision under this license agreement, including failure to make payments to Rigel when due or failure to use commercially reasonable efforts
to find a third party to develop and commercialize a JAK inhibitor, Rigel has the right to terminate our license, and upon the effective date of
such termination, our right to practice the licensed Rigel’s patent rights and other intellectual property would end, which would negatively impact
our ability to find a potential third-party partner to develop, obtain marketing approval for and commercialize ATI-501 and ATI-502. 

38

If  we  breach  our  agreement  with  the  Selling  Stockholders  of  Vixen,  it  could  compromise  our  ability  to  identify  and  consummate
transactions  with  potential  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and  commercialize  our  JAK  inhibitors,
ATI-501 and ATI-502.

In March 2016, we entered into a stock purchase agreement with the stockholders of Vixen, pursuant to which we purchased all of the
stock of Vixen and assumed its license agreement with Columbia University.  If we fail to use commercially reasonable efforts to develop and
commercialize a JAK inhibitor for alopecia, the license agreement with Columbia University will be transferred to the Selling Stockholders of
Vixen following any adverse resolution of any dispute relating thereto.  Upon the effective date of such transfer, our right to practice the licensed
Columbia University patent rights and know-how would end, which would negatively impact our ability to find a potential third-party partner to
develop, obtain marketing approval for and commercialize ATI-501 and ATI-502. 

If we breach our agreement with Columbia University, it could compromise our ability to find a potential third-party partner to develop,

obtain marketing approval for and commercialize our JAK inhibitors, ATI-501 and ATI-502.

In  March  2016,  as  part  of  the  Vixen  acquisition,  we  assumed  a  license  agreement  with  Columbia  University,  which  grants  us  the  right
under certain patent rights and know-how owned by Columbia University relating to the use of JAK inhibitors to treat hair-loss disorders. If we
materially  breach  or  fail  to  perform  any  provision  under  this  license  agreement,  including  failure  to  make  payments  to  Columbia  University
when due and failure to use commercially reasonable efforts to develop and commercialize a licensed product, Columbia University has the right
to terminate our license, and upon the effective date of such termination, our right to practice the licensed Columbia University patent rights and
know-how would end, which would negatively impact our ability to find a potential third-party partner to develop, obtain marketing approval for
and commercialize ATI-501 and ATI-502. 

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

Filing,  prosecuting  and  defending  patents  on  our  drug  candidates  in  all  countries  throughout  the  world  would  be  prohibitively
expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States.
For  example,  the  use  of  A-101  45%  Topical  Solution  for  the  treatment  of  warts  is  currently  covered  by  issued  patents  in  the  United  States,
Australia,  India  and  New  Zealand,  but  not  in  the  European  Union  or  other  countries.  An  additional  four  U.S.  patents  are  issued,  and  patent
applications are pending in the United States, the European Union and other foreign countries directed to high-concentration hydrogen peroxide
formulations, including ESKATA and/or A-101 45% Topical Solution and methods of use.

Our  lead  inhibitor  of  the  MK2  signaling  pathway,  ATI-450,  is  currently  covered  in  patents  and  applications  in  the  United  States,
European Union and other major foreign markets.  We currently do not have any patents issued directed to our lead soft-JAK inhibitor, ATI-1777,
or our lead ITK inhibitor, ATI-2138. Our JAK inhibitors, ATI-501 and ATI-502, are currently covered in patents and applications in the United
States, the European Union, and other major foreign markets. Additionally, U.S., European, Japanese, and South Korean patents have issued in
the patent portfolio licensed from Columbia University, which are directed to the use of certain third-party JAK inhibitors for the treatment of
hair loss disorders and applications are pending in the United States and South Korea.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions.
The  legal  systems  of  some  countries  do  not  favor  the  enforcement  of  patents  and  other  intellectual  property  protection,  which  could  make  it
difficult for us to stop the infringement of our patents generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in
substantial  costs  and  divert  our  efforts  and  attention  from  other  aspects  of  our  business,  could  put  our  patents  at  risk  of  being  invalidated  or
interpreted narrowly and our 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. 

Many  countries,  including  European  Union  countries,  India,  Japan  and  China,  have  compulsory  licensing  laws  under  which  a  patent
owner may be compelled under specified circumstances to grant licenses to third parties. In those countries, we may have limited remedies if
patents are infringed or if we are compelled to grant a license to a third party, which could materially diminish the value of those patents. This
could limit our ability to pursue strategic alternatives, including identifying and consummating transactions with potential third-party partners, to
further develop, obtain marketing approval for and/or commercialize our drug candidates, and consequently our potential revenue opportunities.

39

 
 
 
 
 
 
 
 
 
Table of Contents

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.

We may need to license intellectual property from third parties, and such licenses may not be available or may not be available on

commercially reasonable terms.

A  third  party  may  hold  intellectual  property,  including  patent  rights,  that  are  important  or  necessary  to  the  development  and/or
commercialization  of  our  drug  candidates.  For  example,  we  exclusively  license  intellectual  property  from  Rigel  in  the  field  of  dermatology
related to our JAK inhibitors, ATI-501 and ATI-502.  We also exclusively license intellectual property from Columbia University related to the
use of JAK inhibitors for the treatment of hair loss disorders.  It may be necessary for our potential third-party partners to use the patented or
proprietary technology of third parties to further develop and/or commercialize our drug candidates. If our potential third-party partners are not
able to obtain a license from these third parties on commercially reasonable terms, our business could be harmed, possibly materially. 

Our  third-party  licensors  may  develop  JAK  inhibitors,  including  those  related  to  our  drug  candidates,  outside  of  the  field  of

dermatology.

We exclusively license intellectual property from Rigel in order to develop, use, manufacture, sell and commercialize ATI-501 and ATI-
502  in  the  field  of  dermatology.  Rigel  has  retained  the  rights  under  such  intellectual  property  to  develop,  use,  manufacture,  sell  and
commercialize ATI-501 and ATI-502 outside of the field of dermatology. If Rigel were to commercialize such JAK inhibitors outside the field of
dermatology, such a product could possibly be used off-label for a dermatology indication, which could negatively impact our ability to identify
and  consummate  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  those  drug
candidates for dermatological indications, which in turn would impact our ability to earn revenue from the arrangements with such third-party
partners. Rigel also retained the intellectual property rights to develop, use, manufacture, sell and commercialize other structurally similar JAK
inhibitors.  If  Rigel  commercializes  a  structurally  similar  JAK  inhibitor,  such  a  product  could  directly  compete  with  our  JAK  inhibitor  drug
candidates, if they are approved. 

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which

would be uncertain and could have a material adverse effect on the success of our business.

Our  success  depends  upon  our  ability  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with
potential third-party partners, to develop, obtain marketing approval for and/or commercialize our drug candidates and earn revenue from those
partnerships,  and  for  our  proprietary  technologies  to  be  used  without  infringing  the  proprietary  rights  of  third  parties.  There  is  considerable
intellectual  property  litigation  in  the  biotechnology  and  pharmaceutical  industries.  We  may  become  party  to,  or  threatened  with,  future
adversarial  proceedings  or  litigation  regarding  intellectual  property  rights  with  respect  to  our  drug  candidates  and  technologies,  including
interference or derivation proceedings before the USPTO. Numerous U.S. and foreign issued patents and pending patent applications owned by
third parties exist in the fields in which we are developing our drug candidates. Third parties may assert infringement claims against us based on
existing patents or patents that may be granted in the future.

If we or our potential third-party partners are found to infringe a third party’s intellectual property rights, we or such partners could be
required to obtain a license from such third party to continue developing or commercializing our drug candidates and technology. However, we
or our third-party partners may not be able to obtain any required license on commercially reasonable terms or at all. Even if we or our third-
party partner were able to obtain a license, it could be non-exclusive, thereby giving competitors access to the same technologies licensed to us
or our partner. Consequently, we or our third-party partner could be forced, including by court order, to cease developing or commercializing the
infringing technology or drug candidate. In addition, we or our third-party partner could be found liable for monetary damages, including treble
damages and attorneys’ fees if we or such partner are found to have willfully infringed a patent. A finding of infringement could prevent our
third-party partners from commercializing our drug candidates, if approved, or force such partners to cease some of their business operations. In
the event of a successful claim of infringement against us or our potential third-party partners, we or our third-party partners may have to pay
substantial damages, including treble damages and attorneys’ fees for willful infringement, pay royalties, redesign our infringing drug candidate
or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary expenditure. Claims that we
have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

Table of Contents

We may be subject to claims by third parties asserting that we, our employees or our licensors have misappropriated their intellectual

property, or claiming ownership of what we regard as our own intellectual property.

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

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

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

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

responsibilities.

Even  if  resolved  in  our  favor,  litigation  or  other  legal  proceedings  relating  to  intellectual  property  claims  may  cause  us  to  incur
significant expenses, and could distract our technical and management personnel from their normal responsibilities. In addition, there could be
public  announcements  of  the  results  of  hearings,  motions  or  other  interim  proceedings  or  developments  and  if  securities  analysts  or  investors
perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Such litigation or proceedings
could  substantially  increase  our  operating  losses  and  reduce  the  resources  available  for  development  activities.  We  may  not  have  sufficient
financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of
such litigation or proceedings more effectively than we can because of their greater financial resources. Some of our competitors are larger than
we are and have substantially greater resources. They are, therefore, likely to be able to sustain the costs of complex patent litigation longer than
we could. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual
property.  Litigation  could  result  in  substantial  costs  and  diversion  of  management  resources,  which  could  harm  our  business.  In  addition,  the
uncertainties associated with litigation could compromise our ability to compete in the marketplace, including compromising our ability to raise
the funds necessary to continue our clinical trials, continue our internal research programs, or pursue strategic alternatives, including identifying
and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug
candidates.

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

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

41

 
 
 
 
 
 
 
 
Table of Contents

that  technology  or  information  to  compete  with  us.  If  any  of  our  trade  secrets  were  to  be  disclosed  to  or  independently  developed  by  a
competitor, our competitive position would be harmed. 

The validity, scope and enforceability of any of our patents that cover any of our commercial products or any of our drug candidates

can be challenged by competitors.

The likelihood that a third party will challenge the patents covering a commercial product is increased because it is a marketed product.
The challenge may come in the form of a patent office proceeding, such as an inter partes review, challenging the validity of the patents or a
district court proceeding, such as a paragraph IV litigation arising out of the filing of an ANDA.

If a third party files an ANDA or 505(b)(2) application for a generic of a commercial product, and relies in whole or in part on studies
conducted by or for us, the third party will be required to certify to the FDA that either: (1) there is no patent information listed in the FDA’s
Orange Book with respect to our NDA for the applicable approved drug; (2) the patents listed in the Orange Book have expired; (3) the listed
patents have not expired, but will expire on a particular date and approval is sought after patent expiration; or (4) the listed patents are invalid or
will  not  be  infringed  by  the  manufacture,  use  or  sale  of  the  third  party's  generic  drug.  A  certification  that  the  new  drug  will  not  infringe  the
Orange Book-listed patents for the applicable approved drug, or that such patents are invalid, is called a paragraph IV certification. If the third
party submits a paragraph IV certification to the FDA, a notice of the paragraph IV certification must also be sent to us once the third party’s
ANDA is accepted for filing by the FDA. We may then initiate a lawsuit to defend the patents identified in the notice. The filing of a patent
infringement lawsuit within 45 days of receipt of the notice automatically prevents the FDA from approving the third party’s ANDA until the
earliest of 30 months or the date on which the patent expires, the lawsuit is settled, or the court reaches a decision in the infringement lawsuit in
favor of the third party. If we do not file a patent infringement lawsuit within the required 45-day period, the third party’s ANDA will not be
subject to the 30-month stay of FDA approval. Litigation or other proceedings to enforce or defend intellectual property rights are often very
complex in nature, may be very expensive and time-consuming, may divert our management's attention from our core business, and may result in
unfavorable results that could limit our ability to prevent third parties from competing with our commercial products. 

On October 8, 2019, we, together with Allergan, Inc., filed a patent infringement lawsuit in the U.S. District Court for the District of
Delaware  against  Taro  Pharmaceuticals,  Inc.,  or  Taro,  related  to  an  ANDA  that  Taro  filed  with  the  FDA  to  market  a  generic  version  of
RHOFADE.  The lawsuit claims infringement of U.S. Patent Nos. 7,812,049, 8,420,688, 8,815,929, 9,974,773 and 10,335,391, which are listed
in  the  FDA’s  Approved  Drug  Products  with  Therapeutic  Equivalence  Evaluations,  commonly  known  as  the  Orange  Book,  for  RHOFADE.
 We received a Paragraph IV Notice Letter from Taro dated August 28, 2019, advising that Taro had submitted an ANDA to the FDA seeking
approval from the FDA to manufacture and market a generic version of RHOFADE prior to the expiration of the Orange Book-listed patents. EPI
Health, as purchaser of our rights to RHOFADE, has been substituted for us as a plaintiff party. If EPI Health is not able to successfully defend
the RHOFADE intellectual property and a generic version of RHOFADE is approved, our ability to earn revenue from EPI Health through the
achievement of sales milestones, licensing in jurisdictions outside of the United States and/or royalty payments would be negatively impacted.

If any of our drug candidates advance through development or are approved by the FDA, one or more third parties may challenge the
current patents, or patents that may issue in the future, within our portfolio covering these drug candidates. Any such challenge could result in the
invalidation of, or render unenforceable, some or all of the relevant patent claims or a finding of non-infringement.  

If  we  do  not  obtain  protection  under  the  Hatch-Waxman  Act  by  extending  the  patent  term  and  obtaining  data  exclusivity  for  our

drug candidates, our business may be materially harmed.

Our  success  will  largely  depend  on  our  ability  to  obtain  and  maintain  patent  and  other  intellectual  property  in  the  United  States  and
other countries with respect to our proprietary technology, drug candidates and our target indications.  Our issued U.S. patents covering ATI-450,
our lead inhibitor of the MK2 signaling pathway, expire in 2034 and other issued patents covering different MK2 signaling pathway inhibitors
expire in 2031 and 2032. We currently do not have any patents issued directed to our lead soft-JAK inhibitor, ATI-1777, but any claims that may
issue would expire in 2038. We currently do not have any patents issued directed to our lead ITK inhibitor, ATI-2138, but any claims that may
issue  would  expire  in  2039.    Our  issued  patents  covering  other  novel  inhibitors  of  ITK  expire  between  2035  and  2038.  Certain  issued  U.S.
patents relating to our JAK inhibitors, ATI-501 and ATI-502, are scheduled to expire in 2023 and

42

 
 
 
 
 
 
 
Table of Contents

additional U.S. patents, with claims specifically directed to such JAK inhibitors, are scheduled to expire in 2030.  The issued U.S., European,
Japanese and South Korean patents licensed from Columbia University relating to the use of certain third-party JAK inhibitors for the treatment
of  hair  loss  disorders,  including  AA  and  AGA,  and  inducing  hair  growth,  expire  in  2031.    Our  issued  U.S.  patent  with  claims  directed  to
treatment of SK with ESKATA is scheduled to expire in 2022 and our issued U.S. formulation and applicator patents with claims directed to
high-concentration hydrogen peroxide formulations and applicators containing the same, including A-101 45% Topical Solution and ESKATA,
and methods of use is scheduled to expire in 2035.  Given the amount of time required for the development, testing and regulatory review of new
drug  candidates,  patents  protecting  our  drug  candidates  might  expire  before  or  shortly  after  such  candidates  begin  to  be  commercialized.  We
expect to seek extensions of patent terms in the United States and, if available, in other countries where we are prosecuting patents.

Depending upon the timing, duration and specifics of FDA marketing approval of our drug candidates, one or more of our U.S. patents
may be eligible for limited patent term extension under The Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-
Waxman Act, for a drug candidate. The Hatch-Waxman Act permits a patent extension term of up to five years beyond the normal expiration of
the patent as compensation for patent term lost during development and the FDA regulatory review process, which is limited to the approved
indication  (or  any  additional  indications  approved  during  the  period  of  extension).  However,  the  total  patent  term  including  the  period  of
extension  cannot  exceed  14  years  from  the  product’s  approval  date.    Furthermore,  this  extension  is  limited  to  only  one  patent  per  regulatory
review period that covers the approved product. However, the applicable authorities, including the FDA and the USPTO in the United States, and
any  equivalent  regulatory  authority  in  other  countries,  may  not  agree  with  our  assessment  of  whether  such  extensions  are  available,  and  may
refuse to grant extensions to our patents, or may grant more limited extensions than we request. We may not be granted an extension because of,
for example, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy
applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request.

If we are unable to extend the expiration date of our existing patents or obtain new patents with longer expiry dates, our competitors
may  be  able  to  take  advantage  of  our  investment  in  development  and  clinical  trials  by  referencing  our  clinical  and  preclinical  data  to  obtain
approval of competing products following our patent expiration and launch their product earlier than might otherwise be the case.

Any trademarks we have obtained or may obtain may be infringed or successfully challenged, resulting in harm to our business.

We expect to rely on trademarks as one means to distinguish our products, services or technologies from those of our competitors. Once
we select new trademarks and apply to register them, our trademark applications may not be approved. Third parties may oppose or attempt to
cancel  our  trademark  applications  or  trademarks,  or  otherwise  challenge  our  use  of  the  trademarks.  In  the  event  that  our  trademarks  are
successfully challenged, our products, services or technologies may need to be rebranded, which could result in loss of brand recognition and
could require us to devote resources to advertising and marketing new brands. Our competitors may infringe our trademarks and we may not
have adequate resources to enforce our trademarks.

Outside of the United States we cannot be certain that any country’s patent or trademark office will not implement new rules that

could seriously affect how we draft, file, prosecute and maintain patents, trademarks and patent and trademark applications.

We  cannot  be  certain  that  the  patent  or  trademark  offices  of  countries  outside  the  United  States  will  not  implement  new  rules  that
increase costs for drafting, filing, prosecuting and maintaining patents, trademarks and patent and trademark applications or that any such new
rules will not restrict our ability to file for patent protection. For example, we may elect not to seek patent protection in some jurisdictions or for
some  drug  candidates  in  order  to  save  costs.  We  may  be  forced  to  abandon  or  return  the  rights  to  specific  patents  due  to  a  lack  of  financial
resources.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The  degree  of  future  protection  afforded  by  our  intellectual  property  rights  is  uncertain  because  intellectual  property  rights  have
limitations,  and  may  not  adequately  protect  our  business,  or  permit  us  to  maintain  our  competitive  advantage.  The  following  examples  are
illustrative:

43

others  may  be  able  to  make  formulations  or  compositions  that  are  the  same  as  or  similar  to  A-101  45%  Topical  Solution  and
ESKATA but that are not covered by the claims of the patents that we own;
others may be able to make a JAK inhibitor that is similar to the JAK inhibitors we intend to partner that is not covered by the
patents that we exclusively license and have the right to enforce;
we, our licensors or any third-party partners might not have been the first to make the inventions covered by the issued patents or
pending patent applications that we own;
we,  our  licensors  or  any  third-party  partners  might  not  have  been  the  first  to  file  patent  applications  covering  certain  of  our
inventions;
others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our
intellectual property rights;
it is possible that our pending patent applications will not lead to issued patents;
issued patents that we own or exclusively license may not provide us with any competitive advantages, or may be held invalid or
unenforceable as a result of legal challenges;
our  competitors  might  conduct  research  and  development  activities  in  the  United  States  and  other  countries  that  provide  a  safe
harbor from patent infringement claims for certain research and development activities, as well as in countries where we do not
have  patent  rights,  and  then  use  the  information  learned  from  such  activities  to  develop  competitive  products  for  sale  in  major
commercial markets; and
we may not develop additional proprietary technologies that are patentable.

Risks Related to Regulatory Approval of Our Drug Candidates and Other Legal Compliance Matters

If our potential third-party partners are not able to obtain, or if there are delays in obtaining, required regulatory approvals, our
drug candidates will not be able to be commercialized, and our ability to earn revenue from arrangements with such third-party partners will
be materially impaired.

Our  drug  candidates  and  the  activities  associated  with  their  development  and  commercialization,  including  their  design,  testing,
manufacture,  safety,  efficacy,  recordkeeping,  labeling,  storage,  approval,  advertising,  promotion,  sale  and  distribution,  are  subject  to
comprehensive  regulation  by  the  FDA  and  other  regulatory  agencies  in  the  United  States  and  by  the  European  Commission  and  EU  Member
State  Competent  Authorities  and  similar  regulatory  authorities  outside  the  United  States.  Failure  to  obtain  marketing  approval  for  a  drug
candidate will prevent our potential third-party partners from commercializing the drug candidate. We have only limited experience in filing and
supporting the applications necessary to gain marketing approvals. Securing marketing approval requires the submission of extensive preclinical
and clinical data and supporting information to regulatory authorities for each therapeutic indication to establish the drug candidate’s safety and
efficacy. Securing marketing approval also requires the submission of information about the drug manufacturing process to, and inspection of
manufacturing facilities by, the regulatory authorities. Our drug candidates may not be effective, may be only moderately effective or may prove
to  have  undesirable  or  unintended  side  effects,  toxicities  or  other  characteristics  that  may  preclude  our  potential  third-party  partners  from
obtaining marketing approval or prevent or limit commercial use. If any of our drug candidates receive marketing approval, the accompanying
label may limit the approved use of our product in this way, which could limit sales of the product. 

The process of obtaining marketing approvals, both in the United States and abroad, is expensive and may take many years if additional
clinical trials are required, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity
and novelty of the drug candidates involved. Changes in marketing approval policies during the development period, changes in or the enactment
of additional statutes or regulations, or changes in regulatory review for each submitted drug application, may cause delays in the approval or
rejection of an application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or
may  decide  that  our  data  is  insufficient  for  approval  and  require  additional  preclinical,  clinical  or  other  studies.  In  addition,  varying
interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent marketing approval of a drug candidate. Any
marketing approval our potential third-party partners ultimately obtain may be limited or subject to restrictions or post-approval commitments
that render the approved drug not commercially viable.

If our potential third-party partners experience delays in obtaining approval or if they fail to obtain approval of our drug candidates, the
commercial prospects for our drug candidates may be harmed and our ability to earn revenue from arrangements with such third-party partners
will be materially impaired.

44

 
 
 
 
 
 
Table of Contents

Failure to obtain marketing approval in international jurisdictions would prevent our drug candidates from being marketed abroad.

In order to market and sell our drugs in the European Union and any other jurisdictions, our potential third-party partners must obtain
separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries
and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The
regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in
many countries outside the United States, it is required that the drug be approved for reimbursement before the drug can be approved for sale in
that country. Our potential third-party partners may not obtain approvals from regulatory authorities outside the United States on a timely basis,
if  at  all.  Approval  by  the  FDA  does  not  ensure  approval  by  regulatory  authorities  in  other  countries  or  jurisdictions,  and  approval  by  one
regulatory  authority  outside  the  United  States  does  not  ensure  approval  by  regulatory  authorities  in  other  countries  or  jurisdictions  or  by  the
FDA. However, failure to obtain approval in one jurisdiction may impact our potential third-party partners’ ability to obtain approval elsewhere.
Our potential third-party partners may not be able to file for marketing approvals and may not receive necessary approvals to commercialize our
drug candidates in any market.

A variety of risks associated with marketing our drug candidates by our potential third-party partners internationally could harm

our business.

If our drug candidates are marketed internationally by our potential third-party partners, if approved, our potential third-party partners

would be subject to additional risks related to operating in foreign countries, including:

·
·

·
·
·
·
·
·

·
·
·

·

·
·
·

differing regulatory requirements in foreign countries;
the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts
to import goods from a foreign market (with low or lower prices) rather than buying them locally;
unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements;
economic weakness, including inflation, or political instability in particular foreign economies and markets;
foreign reimbursement, pricing and insurance regimes;
compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;
foreign taxes, including withholding of payroll taxes;
foreign  currency  fluctuations,  which  could  result  in  increased  operating  expenses  and  reduced  revenue,  and  other  obligations
incident to doing business in another country;
difficulties staffing and managing foreign operations;
workforce uncertainty in countries where labor unrest is more common than in the United States;
potential  liability  under  the  U.S.  Foreign  Corrupt  Practices  Act  of  1977,  as  amended,  or  the  FCPA,  or  comparable  foreign
regulations;
challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and
protect intellectual property rights to the same extent as the United States;
production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad;
logistical challenges resulting from distributing our drug candidates to foreign countries; and
business interruptions resulting from geo-political actions, including war and terrorism.

These  and  other  risks  associated  with  international  operations  may  compromise  our  ability  to  earn  revenue  from  arrangements  with

potential third-party partners for our drug candidates.

Any  drug  candidate  for  which  our  potential  third-party  partners  obtain  marketing  approval  could  be  subject  to  post-marketing
restrictions or recall or withdrawal from the market, and our potential third-party partners may be subject to penalties if they fail to comply
with regulatory requirements or if they experience unanticipated problems with our drug candidates, when and if any of them are approved.

Any  drug  candidate  for  which  our  potential  third-party  partners  obtain  marketing  approval,  along  with  the  manufacturing  processes,
post-approval clinical data, labeling, advertising and promotional activities for such drug candidate, will be subject to continual requirements of
and review by the FDA and other regulatory authorities. These

45

 
 
 
 
 
 
Table of Contents

requirements  include  submissions  of  safety  and  other  post-marketing  information  and  reports,  registration  and  listing  requirements,  cGMP
requirements  relating  to  manufacturing,  quality  control,  quality  assurance  and  corresponding  maintenance  of  records  and  documents,
requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval of a drug candidate is granted,
the approval may be subject to limitations on the indicated uses for which the drug candidate may be marketed or to the conditions of approval,
including the requirement to implement a risk evaluation and mitigation strategy. If any of our drug candidates receives marketing approval, the
accompanying label may limit the approved use of our drug, which could limit sales of the drug by our potential third-party partners.

The  FDA  may  also  impose  requirements  for  costly  post-marketing  studies  or  clinical  trials  and  surveillance  to  monitor  the  safety  or
efficacy of the drug. The FDA closely regulates the post-approval marketing and promotion of drugs to ensure drugs are marketed only for the
approved indications and in accordance with the provisions of the approved labeling. The FDA imposes stringent restrictions on manufacturers’
communications regarding off-label use and if our potential third-party partners do not market our drugs for their approved indications, they may
be subject to enforcement action for off-label marketing. Violations of the FDCA relating to the promotion of prescription drugs may lead to
investigations alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with our drugs, manufacturers or manufacturing

processes, or failure to comply with regulatory requirements, may have negative consequences, including:

·
·
·
·
·
·
·
·
·
·
·
·
·

restrictions on such drugs, manufacturers or manufacturing processes;
restrictions on the labeling or marketing of a drug;
restrictions on drug distribution or use;
requirements to conduct post-marketing studies or clinical trials;
warning letters;
recall or withdrawal of the drugs from the market;
refusal to approve pending applications or supplements to approved applications;
clinical holds;
fines, restitution or disgorgement of profits or revenue;
suspension or withdrawal of marketing approvals;
refusal to permit the import or export of our drugs;
drug seizure; or
injunctions or the imposition of civil or criminal penalties.

Non-compliance  with  the  European  Union’s  requirements  regarding  safety  monitoring  or  pharmacovigilance,  and  with  requirements
related to the development of drugs for the pediatric population, can also result in significant financial penalties. Similarly, failure to comply with
the European Union’s requirements regarding the protection of personal information can also lead to significant penalties and sanctions. These
and  other  risks  associated  with  the  failure  by  our  potential  third-party  partners  to  comply  with  regulatory  requirements  may  compromise  our
ability to earn revenue from arrangements with such third-party partners for our drug candidates.

Our  potential  third-party  partners’  relationships  with  third-party  payors,  health  care  professionals  and  customers  in  the  United
States  and  elsewhere  may  be  subject,  directly  or  indirectly,  to  applicable  anti-kickback,  fraud  and  abuse,  false  claims,  physician  payment
transparency, health information privacy and security and other health care laws and regulations, and any failure to comply with such laws
and regulations could have a material adverse effect on our ability to earn revenue from arrangements with such third-party partners for our
drug candidates.

Health  care  providers,  physicians  and  third-party  payors  in  the  United  States  and  elsewhere  will  play  a  primary  role  in  the
recommendation  and  prescription  of  any  of  our  drug  candidates  for  which  marketing  approval  is  obtained.  Our  potential  third-party  partners’
arrangements with third-party payors, health care professionals and customers may expose them to broadly applicable fraud and abuse and other
health care laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal civil False Claims Act, that may
constrain the business or financial arrangements and relationships through which they sell, market and distribute any drug candidates for which
marketing approval is obtained. In addition, we and our potential third-party partners may be subject to transparency laws and patient

46

 
 
 
Table of Contents

privacy  regulation  by  the  federal  government  and  by  the  U.S.  states  and  foreign  jurisdictions  in  which  we  or  they  conduct  business.  The
applicable federal, state and foreign health care laws and regulations that may affect our or our potential third-party partners’ ability to operate
include the following:

·

·

·

·

·

·

the  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  persons  and  entities  from  knowingly  and  willfully
soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return
for, either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment
may be made under federal and state health care programs such as Medicare and Medicaid. Further, several courts have interpreted
the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of
federal health care covered business, the Anti-Kickback Statute has been violated.  The intent standard was further amended by the
Affordable Care Act, to a stricter standard such that a person or entity no longer needs to have actual knowledge of the statute or
specific intent to violate it in order to have committed a violation.  Moreover, the government may assert that a claim including
items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes
of the False Claims Act;
federal civil and criminal false claims laws, including, without limitation, the federal civil False Claims Act (that can be enforced
through civil whistleblower or qui tam actions), and the civil monetary penalties law, which impose criminal and civil penalties,
against  individuals  or  entities  for  knowingly  presenting,  or  causing  to  be  presented,  to  the  federal  government,  including  the
Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or
conceal an obligation to pay money to the federal government;
federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  which  imposes  criminal  and  civil  liability  for,
among other things, executing a scheme to defraud any health care benefit program or making false statements relating to health
care matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute
or specific intent to violate it to have committed a violation;
HIPAA, as amended by HITECH, and their respective implementing regulations, which impose obligations on covered health care
providers, health plans, and health care clearinghouses, as well as their business associates that create, receive, maintain or transmit
individually identifiable health information for or on behalf of a covered entity, with respect to safeguarding the privacy, security
and transmission of individually identifiable health information;
the federal Open Payments program, created under Section 6002 of the Affordable Care Act (commonly known as the Physician
Payments Sunshine Act) and its implementing regulations, which requires specified manufacturers of drugs, devices, biologics or
medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid  or  the  Children’s  Health  Insurance  Program,  with
specific exceptions, to report annually to CMS information related to payments or other “transfers of value” made to physicians,
which  is  defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors,  and  teaching  hospitals,  as  well  as
applicable  manufacturers  to  report  annually  to  CMS  ownership  and  investment  interests  held  by  physicians  and  their  immediate
family members. All such reported information is publicly available; and
analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or
marketing  arrangements  and  claims  involving  health  care  items  or  services  reimbursed  by  non-governmental  third-party  payors,
including  private  insurers;  state  and  foreign  laws  that  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical
industry’s  voluntary  compliance  guidelines  and  the  relevant  compliance  guidance  promulgated  by  the  federal  government  or
otherwise restrict payments that may be made to health care providers; state, local and foreign laws that require drug manufacturers
to report information related to payments and other transfers of value to physicians and other health care providers or marketing
expenditures; state laws that require drug manufacturers to report pricing information regarding certain drugs; and/or that require
registration of certain employees engaged in marketing activities in the location; and state and foreign laws governing the privacy
and security of health information in certain circumstances, many of which differ from each other in significant ways and often are
not preempted by HIPAA, thus complicating compliance efforts.

Efforts  to  ensure  that  our  or  our  potential  third-party  partners’  business  arrangements  with  third  parties  will  comply  with  applicable
health care laws and regulations may involve substantial costs. It is possible that governmental authorities will conclude that our or our potential
third-party partners’ business practices, including relationships with physicians and other health care providers, some of whom may recommend,
purchase and/or prescribe our drug candidates,

47

 
 
Table of Contents

if approved, may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other health care
laws and regulations. By way of example, some of our consulting arrangements with physicians may not meet all of the criteria of the personal
services  safe  harbor  under  the  federal  Anti-Kickback  Statute.  Accordingly,  they  may  not  qualify  for  safe  harbor  protection  from  government
prosecution. A business arrangement that does not substantially comply with a safe harbor, however, is not necessarily illegal under the Anti-
Kickback Statute, but may be subject to additional scrutiny by the government.

If  our  or  our  potential  third-party  partners’  operations  are  found  to  be  in  violation  of  any  of  these  laws  or  any  other  governmental
regulations that may apply to us or them, we or our potential third-party partners may be subject to significant civil, criminal and administrative
penalties,  including,  without  limitation,  damages,  fines,  disgorgement,  imprisonment,  exclusion  from  participation  in  government  health  care
programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we or they become subject to a corporate integrity
agreement  or  similar  agreement  to  resolve  allegations  of  non-compliance  with  these  laws  and  the  curtailment  or  restructuring  of  our  or  their
operations, which could have a material adverse effect on our ability to earn revenue from arrangements with such third-party partners for our
drug candidates. If any physician or other health care provider or entity with whom we or our potential third-party partners expect to do business
is  found  not  to  be  in  compliance  with  applicable  laws,  it  may  be  subject  to  significant  criminal,  civil  or  administrative  sanctions,  including
exclusions  from  participation  in  government  health  care  programs,  which  could  also  materially  affect  our  ability  to  earn  revenue  from
arrangements with such third-party partners for our drug candidates.

Recently  enacted  and  future  legislation  may  increase  the  difficulty  and  cost  for  our  potential  third-party  partners  to  obtain
marketing approval of our drug candidates and commercialize our drug candidates, if approved, and affect the prices our potential third-
party partners 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 of our drug candidates, restrict or regulate post-approval
activities  and  affect  our  potential  third-party  partners’  ability  to  profitably  sell  any  of  our  drug  candidates  for  which  our  potential  third-party
partners obtain marketing approval, and consequently affect our ability to earn revenue from arrangements with such third-party partners for our
drug candidates.

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in health care
systems with the stated goals of containing health care costs, improving quality and/or expanding access. In the United States, the pharmaceutical
industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.  The Affordable Care Act,
which was signed into law in 2010, is a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of health
care spending, enhance remedies against fraud and abuse, add new transparency requirements for the health care and health insurance industries,
impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the Affordable Care Act of importance to commercial products are the following:

·

·

·

·

·

·

an  annual,  nondeductible  fee  on  any  entity  that  manufactures  or  imports  certain  branded  prescription  drugs  and  biologic  agents,
apportioned among these entities according to their market share in certain government health care programs;
an  increase  in  the  statutory  minimum  rebates  a  manufacturer  must  pay  under  the  Medicaid  Drug  Rebate  Program  to  23.1%  and
13.0% of the average manufacturer price for branded and generic drugs, respectively;
expansion  of  health  care  fraud  and  abuse  laws,  including  the  False  Claims  Act  and  the  Anti-Kickback  Statute,  which  include,
among other things, new government investigative powers and enhanced penalties for non-compliance;
a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off
negotiated  prices  of  applicable  brand  drugs  to  eligible  beneficiaries  during  their  coverage  gap  period,  as  a  condition  for  the
manufacturer’s outpatient drugs to be covered under Medicare Part D;
extension  of  manufacturers’  Medicaid  rebate  liability  to  covered  drugs  dispensed  to  individuals  who  are  enrolled  in  Medicaid
managed care organizations;
expansion  of  eligibility  criteria  for  Medicaid  programs  by,  among  other  things,  allowing  states  to  offer  Medicaid  coverage  to
additional individuals, thereby potentially increasing manufacturers’ Medicaid rebate liability;

48

 
 
 
 
 
 
Table of Contents

·
·
·
·

expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program;
the new requirements under the federal Open Payments program and its implementing regulations;
a new requirement to annually report drug samples that manufacturers and distributors provide to physicians; and
a  new  Patient-Centered  Outcomes  Research  Institute  to  oversee,  identify  priorities  in,  and  conduct  comparative  clinical
effectiveness research, along with funding for such research.

There  remain  judicial  and  Congressional  challenges  to,  as  well  as  efforts  by  the  Trump  Administration  to  repeal  or  replace  certain
aspects of the Affordable Care Act. As a result, there have been delays in the implementation of, and action taken to repeal or replace, certain
aspects of the Affordable Care Act.  For example, since January 2017, President Trump has signed two executive orders and other directives
designed  to  delay,  circumvent,  or  loosen  certain  requirements  mandated  by  the  Affordable  Care  Act.  Concurrently,  Congress  has  considered
legislation that would repeal or repeal and replace all or part of the Affordable Care Act. While Congress has not passed comprehensive repeal
legislation, two bills affecting the implementation of certain taxes under the Affordable Care Act have been signed into law. The Tax Cuts and
Jobs Act of 2017, or the 2017 Tax Act, includes a provision that repealed, effective January 1, 2019, the tax-based shared responsibility payment
imposed  by  the  Affordable  Care  Act  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”.  Additionally, the 2020 federal spending package permanently eliminates, effective January 1,
2020, the Affordable Care Act-mandated “Cadillac” tax on high-cost employer-sponsored health coverage and medical device tax and, effective
January 1, 2021, also eliminates the health insurer tax.  Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amended
the Affordable Care Act, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut
hole”.  In December 2018, CMS published a new final rule permitting further collections and payments to and from certain Affordable Care Act
qualified health plans and health insurance issuers under the Affordable Care Act risk adjustment program in response to the outcome of federal
district court litigation regarding the method CMS uses to determine this risk adjustment. On December 14, 2018, a Texas U.S. District Court
Judge ruled that the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of
the 2017 Tax Act. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court ruling that the
individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the
Affordable  Care  Act  are  invalid  as  well.  It  is  unclear  how  this  decision,  future  decisions,  subsequent  appeals,  and  other  efforts  to  repeal  and
replace the Affordable Care Act will impact the Affordable Care Act. We continue to evaluate the impact of the Affordable Care Act and efforts
to repeal or replace the Affordable Care Act on our business.

In  addition,  other  legislative  changes  have  been  proposed  and  adopted  since  the  Affordable  Care  Act  was  enacted.  These  changes
included  aggregate  reductions  to  Medicare  payments  to  providers  of  2%  per  fiscal  year  that  became  effective  on  April  1,  2013  and,  due  to
subsequent legislative amendments to the statute, including the BBA, will stay in effect through 2029 unless additional Congressional action is
taken.  The American Taxpayer Relief Act of 2012, which was signed into law in January 2013, among other things, further reduced Medicare
payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three
to five years. Any similar new laws may result in additional reductions in Medicare and other health care funding, which could have a material
adverse effect on our ability to earn revenue from arrangements with our potential third-party partners for our drug candidates.

We expect that the Affordable Care Act, as well as other health care reform measures that may be adopted in the future, may result in
more rigorous coverage criteria and in additional downward pressure on the price that our potential third-party partners receive for any approved
drug candidate. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments
from  private  payors.  The  implementation  of  cost  containment  measures  or  other  health  care  reforms  may  prevent  our  potential  third-party
partners from being able to generate revenue, attain profitability, or commercialize our drug candidates, if approved, which in turn may impact
our ability to earn revenue from arrangements with such third-party partners for our drug candidates.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities
for drugs.  In addition, 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 drug pricing, review the relationship between pricing
and manufacturer patient

programs,  and  reform  government  program  reimbursement  methodologies  for  drugs.  At  the  federal  level,  the  Trump  Administration’s  budget
proposals for fiscal year 2020 contains further drug price control measures that could be enacted during the budget process or in other future
legislation, including, for example, measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to
allow some states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients. Further, the
Trump  Administration  released  a  “Blueprint”,  or  plan,  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  health  care  programs,  incentivize
manufacturers to lower the list price of their drugs, and reduce the out of pocket costs of drug products paid by consumers. The Department of
Health and Human Services, or HHS, has solicited feedback on some of these measures and, has implemented others under its existing authority.
For  example,  in  May  2019,  CMS  issued  a  final  rule  to  allow  Medicare  Advantage  Plans  the  option  of  using  step  therapy  for  Part  B  drugs
beginning  January  1,  2020.  This  final  rule  codified  CMS’  policy  change  that  was  effective  January  1,  2019.  While  some  of  these  and  other
measures  may  require  additional  authorization  to  become  effective,  Congress  and  the  Trump  Administration  have  both  stated  that  they  will
continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures have become increasingly
active in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or
patient reimbursement constraints, discounts, restrictions on certain drug access and marketing cost disclosure and transparency measures, and,
in some cases, designed to encourage importation from other countries and bulk purchasing  We cannot be sure 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
obtaining  marketing  approvals  for  our  drug  candidates,  if  any,  may  be.  In  addition,  increased  scrutiny  by  the  U.S.  Congress  of  the  FDA’s
approval process may significantly delay or prevent marketing approval, as well as subject our potential third-party partners to more stringent
drug labeling and post-marketing testing and other requirements. These risks may compromise our ability to earn revenue from arrangements
with such third-party partners for our drug candidates.

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

In  some  countries,  particularly  the  countries  of  the  European  Union,  the  pricing  of  prescription  pharmaceuticals  is  subject  to
governmental  control.  In  these  countries,  pricing  negotiations  with  governmental  authorities  can  take  considerable  time  after  the  receipt  of
marketing approval for a drug. To obtain coverage and reimbursement or pricing approval in some countries, our potential third-party partners
may  be  required  to  conduct  a  clinical  trial  that  compares  the  cost-effectiveness  of  our  drug  candidate  to  other  available  procedures.  If
reimbursement of our drug candidates is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our potential third-
party partners may not able to generate revenue, which in turn may adversely affect our ability to earn revenue from arrangements with such
third-party partners for our drug candidates. 

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or

incur costs that could harm our business.

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

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

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

The  inherent  dangers  in  production  and  transportation  of  hydrogen  peroxide  could  cause  disruptions  and  could  expose  us  to

potentially significant losses, costs or liabilities.

Our operations are subject to significant hazards and risks inherent in the use and transport of hydrogen peroxide, the active ingredient
in A-101 45% Topical Solution. Hydrogen peroxide can decompose in the presence of organic materials and is categorized as an oxidizer and is
corrosive. Hydrogen peroxide should be stored in cool, dry, well-ventilated areas and away from any flammable or combustible substances. The
hazards  and  risks  associated  with  producing  and  transporting  hydrogen  peroxide  include  fires,  explosions,  third-party  interference  (including
terrorism) and mechanical failure of equipment at our facilities or those of our supplier of hydrogen peroxide. The occurrence of any of these
events  could  result  in  production  and  distribution  difficulties  and  disruptions,  personal  injury  or  wrongful  death  claims  and  other  damage  to
properties.

We  are  subject  to  governmental  economic  sanctions  and  export  and  import  controls  that  could  impair  our  potential  third-party
partners’ ability to compete in international markets or subject us or our potential third-party partners to liability if we or they are not in
compliance with applicable laws.

As a U.S. company, we are subject to U.S. import and export controls and economic sanctions laws and regulations, and we are required
to  import  and  export  our  drug  candidates,  technology  and  services  in  compliance  with  those  laws  and  regulations,  including  the  U.S.  Export
Administration Regulations, the International Traffic in Arms Regulations, and economic embargo and trade sanction programs administered by
the Treasury Department’s Office of Foreign Assets Control. 

U.S. economic sanctions and export control laws and regulations prohibit the shipment of certain products and services to countries,
governments  and  persons  targeted  by  U.S.  sanctions.  While  we  are  currently  taking  precautions  to  prevent  doing  any  business,  directly  or
indirectly, with countries, governments and persons targeted by U.S. sanctions and to ensure that our drug candidates, are not exported or used by
countries, governments and persons targeted by U.S. sanctions, such measures may be circumvented. 

Furthermore, if we or our third-party partners export our drug candidates, the exports may require authorizations, including a license, a
license  exception  or  other  appropriate  government  authorization.  Complying  with  export  control  and  sanctions  regulations  may  be  time-
consuming and may result in the delay or loss of sales opportunities. Failure to comply with export control and sanctions regulations may expose
us or our potential third-party partners to government investigations and penalties. 

If we are found to be in violation of U.S. sanctions or import or export control laws, it could result in civil and criminal, monetary and
non-monetary  penalties,  including  possible  incarceration  for  those  individuals  responsible  for  the  violations,  the  loss  of  export  or  import
privileges and reputational harm.

We  and  our  potential  third-party  partners  are  subject  to  anti-corruption  and  anti-money  laundering  laws  with  respect  to  our  and

their operations and non-compliance with such laws can subject us to criminal and/or civil liability and harm our business.

We and our potential third-party partners are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the
U.S.  Travel  Act,  the  USA  PATRIOT  Act  and  possibly  other  anti-bribery  and  anti-money  laundering  laws  in  countries  in  which  we  conduct
activities.  Anti-corruption  laws  are  interpreted  broadly  and  prohibit  companies  and  their  employees  and  third-party  intermediaries  from
authorizing, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We or our
potential  third-party  partners  may  engage  third-party  intermediaries  in  connection  with  the  development  or  commercialization  of  our  drug
candidates  and  to  obtain  necessary  permits,  licenses  and  other  regulatory  approvals.  We,  our  potential  third-party  partners  or  the  third-party
intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities.
We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors,
partners and agents, even if we do not explicitly authorize such activities. 

Noncompliance  with  anti-corruption  and  anti-money  laundering  laws  could  subject  us  to  whistleblower  complaints,  investigations,
sanctions,  settlements,  prosecution,  other  enforcement  actions,  disgorgement  of  profits,  significant  fines,  damages,  other  civil  and  criminal
penalties or injunctions, suspension and/or debarment from contracting

with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other collateral consequences. Responding to
any action will likely result in a materially significant diversion of management’s attention and resources and significant defense costs and other
professional fees.

Risks Related to Employee Matters and Managing Our Growth

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

We  are  highly  dependent  on  the  management,  development,  clinical,  financial,  legal  and  business  development  expertise  of  Dr.  Neal
Walker, our Chief Executive Officer, Dr. David Gordon, our Chief Medical Officer, Frank Ruffo, our Chief Financial Officer, and Kamil Ali-
Jackson, our Chief Legal Officer, as well as the other members of our scientific and clinical teams. Although we have entered into employment
agreements with certain of our executive officers, each of them may currently terminate their employment with us or resign at any time.  We do
not maintain “key person” insurance for any of our key executives other than for Dr. Walker. 

Recruiting and retaining qualified scientific, manufacturing and clinical personnel will also be critical to our success. The loss of the
services of our executive officers or other key employees could impede the achievement of our development objectives and seriously harm our
ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may
take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to
successfully  develop  and  partner  drug  candidates.  Competition  to  hire  from  this  limited  pool  is  intense,  and  we  may  be  unable  to  hire,  train,
retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies
for  similar  personnel.  We  also  experience  competition  for  the  hiring  of  scientific  and  clinical  personnel  from  universities  and  research
institutions.  In  addition,  we  rely  on  consultants  and  advisors,  including  scientific  and  clinical  advisors,  to  assist  us  in  formulating  our
development strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting
or  advisory  contracts  with  other  entities  that  may  limit  their  availability  to  us.  If  we  are  unable  to  continue  to  attract  and  retain  high  quality
personnel, our ability to pursue our growth strategy will be limited. 

Our employees, independent contractors, consultants, third-party partners, principal investigators, CROs and vendors may engage in

misconduct or other improper activities, including non-compliance with regulatory standards and requirements.

We are exposed to the risk that our employees, independent contractors, consultants, third-party partners, principal investigators, CROs
and vendors may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless and/or
negligent  conduct  or  disclosure  of  unauthorized  activities  to  us  that  violates  FDA  regulations,  including  those  laws  requiring  the  reporting  of
true, complete and accurate information to the FDA, manufacturing standards, federal and state health care laws and regulations, and laws that
require the true, complete and accurate reporting of financial information or data. In particular, sales, marketing and business arrangements by
our potential third-party partners in the health care industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks,
self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and
promotion, sales commission, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the
improper use of individually identifiable information, including, without limitation, information obtained in the course of clinical trials, which
could  result  in  regulatory  sanctions  and  serious  harm  to  our  reputation.  We  have  adopted  a  code  of  business  conduct  and  ethics,  but  it  is  not
always  possible  to  identify  and  deter  misconduct,  and  the  precautions  we  take  to  detect  and  prevent  this  activity  may  not  be  effective  in
controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming
from  a  failure  to  be  in  compliance  with  such  laws  or  regulations.  If  any  such  actions  are  instituted  against  us,  and  we  are  not  successful  in
defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant
civil,  criminal  and  administrative  penalties,  including,  without  limitation,  damages,  fines,  disgorgement,  imprisonment,  exclusion  from
participation  in  government  health  care  programs,  such  as  Medicare  and  Medicaid,  additional  reporting  obligations  and  oversight  if  we  are
subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, and the curtailment or
restructuring of our operations.

Risks Related to Ownership of Our Common Stock

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

Although our common stock is listed on The Nasdaq Global Select Market, we cannot assure you that an active trading market for our
shares will be sustained. If an active market for our common stock is not sustained, it may be difficult for investors in our common stock to sell
shares without depressing the market price for the shares or to sell the shares at all. 

The trading price of the shares of our common stock has been and is likely to continue to be volatile.

Our  stock  price  has  been  and  is  likely  to  continue  to  be  volatile.  The  stock  market  in  general  and  the  market  for  biotechnology
companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies.
As a result of this volatility, investors may not be able to sell their common stock at or above the price paid for the shares. The market price for
our common stock may be influenced by many factors, including:

the commencement, enrollment or results of any clinical trials we may conduct, or changes in the development status of our drug
candidates;
any delay in our regulatory filings for any of our drug candidates and any adverse development or perceived adverse development
with respect to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a
“refusal to file” letter or a request for additional information;
adverse results from, delays in or termination of clinical trials;
adverse regulatory decisions, including failure of any of our drug candidates to receive marketing approval;
unanticipated serious safety concerns related to the use of any drug candidate or previously sold commercial product;
changes in financial estimates by us or by any securities analysts who might cover our stock;
conditions or trends in our industry;
changes in the structure of health care payment systems;
changes in the market valuations of similar companies;
stock  market  price  and  volume  fluctuations  of  comparable  companies  and,  in  particular,  those  that  operate  in  the  biotechnology
industry;
publication  of  research  reports  about  us  or  our  industry  or  positive  or  negative  recommendations  or  withdrawal  of  research
coverage by securities analysts;
announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures;
announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us;
investors’ general perception of our company and our business;
recruitment or departure of key personnel;
overall performance of the equity markets;
trading volume of our common stock;
disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent
protection for our technologies;
significant lawsuits, including patent or stockholder litigation;
general political and economic conditions; and
other events or factors, many of which are beyond our control.

In  the  past,  stockholders  have  initiated  class  action  lawsuits  against  pharmaceutical  companies  following  periods  of  volatility  in  the
market prices of these companies’ stock. For example, two purported class action complaints were filed against us and certain of our executive
officers alleging violations of certain federal securities laws and two stockholder derivative actions were filed against certain of our executive
officers and directors alleging breaches of fiduciary duties.  We and the other defendants dispute the plaintiffs’ claims and intend to defend these
matters vigorously.  We have entered into indemnity agreements with our executive officers and directors which provide, among other things,
that we will indemnify such officer or director, under the circumstances and to the extent provided for therein, for expenses, damages, judgments,
fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or
her position as our director, officer or other agent, and otherwise to the fullest

53

extent  permitted  under  Delaware  law  and  our  bylaws.  These  cases,  and  additional  litigation,  if  instituted  against  us,  could  cause  us  to  incur
substantial costs and divert management’s attention and resources from our business.

If we fail to maintain compliance with the listing requirements of The Nasdaq Global Market, we may be delisted and the price of

our common stock and our ability to access the capital markets could be negatively impacted.

Our common stock is currently listed on The Nasdaq Global Market. To maintain the listing of our common stock on The Nasdaq
Global Market, we are required to meet certain listing requirements, including, among others, either: (i) a minimum closing bid price of $1.00
per share, a market value of publicly held shares (excluding shares held by our executive officers, directors and 10% or more stockholders) of
at least $5 million and stockholders’ equity of at least $10 million; or (ii) a minimum closing bid price of $1.00 per share, a market value of
publicly held shares (excluding shares held by our executive officers, directors, affiliates and 10% or more stockholders) of at least $15 million
and a total market value of listed securities of at least $50.0 million.

We may fail to satisfy one or more Nasdaq Global Market requirements for continued listing of our common stock in the future. There
can be no assurance that we will be successful in maintaining the listing of our common stock on the Nasdaq Global Market, or, if transferred, on
the Nasdaq Capital Market. This could impair the liquidity and market price of our common stock. In addition, the delisting of our common stock
from  a  national  exchange  could  have  a  material  adverse  effect  on  our  access  to  capital  markets,  and  any  limitation  on  market  liquidity  or
reduction in the price of our common stock as a result of that delisting could adversely affect our ability to raise capital on terms acceptable to us,
or at all.

If equity research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or

our market, our stock price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that equity research analysts publish about us or our
business,  our  market  and  our  competitors.  Equity  research  analysts  may  elect  not  to  initiate  or  continue  to  provide  research  coverage  of  our
common stock, and such lack of research coverage may adversely affect the market price of our common stock. Even if we have equity research
analyst coverage, we will not have any control over the analysts or the content and opinions included in their reports. The price of our stock
could decline if one or more equity research analysts downgrade our stock or issue other unfavorable commentary or research. If one or more
equity research analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which
in turn could cause our stock price or trading volume to decline. 

The issuance of additional stock in connection with financings, acquisitions, investments, our equity incentive plan or otherwise will

dilute all other stockholders.

Our  certificate  of  incorporation  authorizes  us  to  issue  up  to  100,000,000  shares  of  common  stock  and  up  to  10,000,000  shares  of
preferred stock with such rights and preferences as may be determined by our board of directors. Subject to compliance with applicable rules and
regulations, we may issue our shares of common stock or securities convertible into our common stock from time to time in connection with a
financing, acquisition, investment, our equity incentive plan or otherwise. Any such issuance could result in substantial dilution to our existing
stockholders and cause the trading price of our common stock to decline. 

Sales of a substantial number of shares of our common stock into the market could cause the market price of our common stock to

drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our stockholders sell, or
the market perceives that our stockholders intend to sell, substantial amounts of our common stock in the public market, the market price of our
common stock could decline significantly.

In addition, we have filed registration statements on Form S-8 under the Securities Act registering the issuance of shares of common
stock subject to options or other equity awards issued or reserved for future issuance under our equity incentive plans. Shares registered under
these  registration  statements  are  available  for  sale  in  the  public  market  subject  to  vesting  arrangements  and  exercise  of  options,  and  the
restrictions of Rule 144 under the Securities Act in the case of our affiliates.

54

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Additionally, certain holders of shares of our common stock, or their transferees, have rights, subject to some conditions, to require us to
file one or more registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or
other stockholders. If we were to register the resale of these shares, they could be freely sold in the public market. If these additional shares are
sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline.

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to
change our management and hinder efforts to acquire a controlling interest in us, and the market price of our common stock may be lower
as a result.

There are provisions in our certificate of incorporation and bylaws that may make it difficult for a third party to acquire, or attempt to
acquire, control of our company, even if a change of control was considered favorable by some or all of our stockholders. For example, our board
of directors has the authority to issue up to 10,000,000 shares of preferred stock. The board of directors can fix the price, rights, preferences,
privileges, and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock
may delay or prevent a change of control transaction. As a result, the market price of our common stock and the voting and other rights of our
stockholders may be adversely affected. An issuance of shares of preferred stock may result in the loss of voting control to other stockholders.

Our charter documents also contain other provisions that could have an anti-takeover effect, including:

·
·
·
·
·

only one of our three classes of directors is elected each year;
stockholders are not entitled to remove directors other than by a 66 2/3% vote and only for cause;
stockholders are not permitted to take actions by written consent;
stockholders cannot call a special meeting of stockholders; and
stockholders must give advance notice to nominate directors or submit proposals for consideration at stockholder meetings.

In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which regulates
corporate acquisitions by prohibiting Delaware corporations from engaging in specified business combinations with particular stockholders of
those companies. These provisions could discourage potential acquisition proposals and could delay or prevent a change of control transaction.
They could also have the effect of discouraging others from making tender offers for our common stock, including transactions that may be in
your  best  interests.  These  provisions  may  also  prevent  changes  in  our  management  or  limit  the  price  that  investors  are  willing  to  pay  for  our
stock.

We  are  an  “emerging  growth  company”  and,  as  a  result  of  the  reduced  disclosure  and  governance  requirements  applicable  to

emerging growth companies, our common stock may be less attractive to investors.

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and we intend
to take advantage of some of the exemptions from reporting requirements that are applicable to other public companies that are not emerging
growth companies, including:

·

·

·

·

·

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

55

We cannot predict if investors will find our common stock less attractive because we will 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 may take advantage of these reporting exemptions until we are no longer an emerging growth company. We currently expect
that we will remain an emerging growth company until December 31, 2020.

We also qualify as a “smaller reporting company” as defined in Rule 12b-2 of the Exchange Act, and so long as we remain a smaller

reporting company, we benefit from some of the same scaled disclosure requirements.

Under Section 107(b) of the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such
time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised
accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not
emerging growth companies.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis

could be impaired.

We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act and the rules and regulations of the stock
market  on  which  our  common  stock  is  listed.  The  Sarbanes-Oxley  Act  requires,  among  other  things,  that  we  maintain  effective  disclosure
controls  and  procedures  and  internal  control  over  financial  reporting,  and  perform  system  and  process  evaluation  and  testing  of  our  internal
control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting. This requires
that  we  incur  substantial  additional  professional  fees  and  internal  costs  to  expand  our  accounting  and  finance  functions  and  that  we  expend
significant management efforts.

We may identify weaknesses in our system of internal financial and accounting controls and procedures that could result in a material
misstatement of our consolidated financial statements. Our internal control over financial reporting will not 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.  Because  of  the  inherent  limitations  in  all  control  systems,  no  evaluation  of  controls  can  provide  absolute
assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

If  we  are  unable  to  maintain  proper  and  effective  internal  controls,  we  may  not  be  able  to  produce  timely  and  accurate  financial
statements, and we may conclude that our internal control over financial reporting is not effective. If that were to happen, the market price of our
stock could decline, and we could be subject to sanctions or investigations by the stock exchange on which our common stock is listed, the SEC,
or other regulatory authorities.

Changes in tax laws or regulations that are applied adversely to us may have a material adverse effect on our business, cash flow,

financial condition or results of operations.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely
affect  our  business  operations  and  financial  performance.  Further,  existing  tax  laws,  statutes,  rules,  regulations  or  ordinances  could  be
interpreted, changed, modified or applied adversely to us. For example, the 2017 Tax Act enacted many significant changes to the U.S. tax laws.
Future guidance from the Internal Revenue Service and other tax authorities with respect to the 2017 Tax Act may affect us, and certain aspects
of  the  2017  Tax  Act  could  be  repealed  or  modified  in  future  legislation.  In  addition,  it  is  uncertain  if  and  to  what  extent  various  states  will
conform to the 2017 Tax Act or any newly enacted federal tax legislation. Changes in corporate tax rates, the realization of net deferred tax assets
relating to our operations, the taxation of foreign earnings, and the deductibility of expenses under the 2017 Tax Act or future reform legislation
could have a material impact on the value of our deferred tax assets, could result in significant one-time charges, and could increase our future
U.S. tax expense.

We might not be able to utilize a significant portion of our net operating loss carryforwards and research and development tax credit

carryforwards.

As of December 31, 2019, we had federal and state net operating loss carryforwards, or NOLs, of $326.1 million and $338.8 million,
respectively, which will begin to expire in 2032.  Under federal income tax law, federal NOLs incurred in 2018 and later years may be carried
forward indefinitely, but the deductibility of such federal NOLs is limited.  It is

56

 
 
 
 
 
 
 
 
 
 
Table of Contents

uncertain if and to what extent various states will conform to the federal tax law.  As of December 31, 2019, we also had federal research and
development  tax  credit  carryforwards  of  $7.3  million  which  will  begin  to  expire  in  2032,  and  state  research  and  development  tax  credit
carryforwards of $0.1 million which will begin to expire in 2022. These net operating loss and tax credit carryforwards could expire unused or
due to limitation on use be unavailable to offset future income tax liabilities.  In addition, under Section 382 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 net operating
loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited.  We have completed an analysis under
Section  382  for  NOLs  generated  from  July  13,  2012  through  December  31,  2018.    Although  we  have  experienced  Section  382  ownership
changes since 2012, we have concluded that we should have sufficient ability to utilize NOLs accumulated during the periods tested.  We have
not yet determined if a Section 382 ownership change has occurred during the year ended December 31, 2019, or for Confluence prior to the
acquisition.  In addition, we may 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. If we determine that an ownership change has occurred and our ability to use our historical net operating
loss  and  tax  credit  carryforwards  is  materially  limited,  it  might  harm  our  future  operating  results  by  effectively  increasing  our  future  tax
obligations. 

We do not anticipate paying any cash dividends on our common stock in the foreseeable future and our stock may not appreciate in

value.

We have not declared or paid cash dividends on our common stock to date. We currently intend to retain our future earnings, if any, to
fund the development and growth of our business. There is no guarantee that shares of our common stock will appreciate in value or that the
price at which our stockholders have purchased their shares will be able to be maintained.

We incur significant costs and demands upon management as a result of being a public company.

As a public company listed in the United States, we incur, and will continue to incur, particularly after we cease to be an “emerging
growth company,” significant legal, accounting and other costs. These costs could negatively affect our financial results. In addition, changing
laws, regulations and standards relating to corporate governance and public disclosure, including regulations implemented by the SEC and The
Nasdaq  Stock  Market,  may  increase  legal  and  financial  compliance  costs  and  make  some  activities  more  time-consuming.  These  laws,
regulations  and  standards  are  subject  to  varying  interpretations  and,  as  a  result,  their  application  in  practice  may  evolve  over  time  as  new
guidance is provided by regulatory and governing bodies. We intend to invest resources to comply with evolving laws, regulations and standards,
and  this  investment  may  result  in  increased  general  and  administrative  expenses  and  a  diversion  of  management’s  time  and  attention  from
revenue-generating activities to compliance activities. If notwithstanding our efforts to comply with new laws, regulations and standards, we fail
to comply, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

Failure to comply with these rules might also make it more difficult for us to obtain some types of insurance, including director and
officer liability insurance, and we might be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the
same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on
our board of directors, on committees of our board of directors or as members of senior management.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the 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 employees.

Our  amended  and  restated  certificate  of  incorporation  provides  that  the  Court  of  Chancery  of  the  State  of  Delaware  is  the  exclusive
forum  for  the  following  types  of  actions  or  proceedings  under  Delaware  statutory  or  common  law:  (i)  any  derivative  action  or  proceeding
brought on our behalf, (ii) any action asserting a claim for breach of a fiduciary duty owed by any of our directors, officers or other employees to
us  or  our  stockholders,  (iii)  any  action  asserting  a  claim  arising  pursuant  to  any  provision  of  the  Delaware  General  Corporation  Law,  our
amended  and  restated  certificate  of  incorporation  or  our  amended  and  restated  bylaws  or  (iv)  any  action  asserting  a  claim  governed  by  the
internal affairs doctrine. However, this exclusive forum provision would not apply to suits brought to enforce a duty or liability created by the
Securities Act or the Exchange Act. The choice of forum provision may limit a stockholder’s ability to bring a claim

57

 
 
 
 
 
 
 
Table of Contents

in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits
against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provision contained in our
amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with
resolving such action in other jurisdictions, which could adversely affect our business and financial condition.    

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

We  currently  sublease  33,019  square  feet  of  space  for  our  headquarters  in  Wayne,  Pennsylvania,  which  has  a  term  through  October
2023, which we use for our therapeutics business.  If for any reason the lease between Chesterbrook Partners, LP, the Landlord, and Auxilium
Pharmaceuticals,  LLC,  the  Sublandlord,  is  terminated  or  expires  prior  to  October  2023,  our  sublease  will  automatically  terminate.    We  also
sublease 21,056 square feet of office and laboratory space in St. Louis, Missouri, which has an initial term through June 2029, which we use for
our therapeutics and contract research businesses.  We have the option to extend the initial term for two additional periods of five years each. We
believe that our facilities are suitable and adequate to meet our current needs.

Item 3. Legal Proceedings

Securities Class Action

On July 30, 2019, plaintiff Linda Rosi, or Rosi, filed a putative class action complaint captioned Rosi v. Aclaris Therapeutics, Inc., et al.
in the U.S. District Court for the Southern District of New York against us and certain of our executive officers.  The complaint alleges that the
defendants  violated  federal  securities  laws  by,  among  other  things,  failing  to  disclose  an  alleged  likelihood  that  regulators  would  scrutinize
advertising materials related to ESKATA and find that the materials minimized the risks or overstated the efficacy of the product.  The complaint
seeks unspecified compensatory damages on behalf of Rosi and all other persons and entities that purchased or otherwise acquired our securities
between May 8, 2018 and June 20, 2019. 

On September 5, 2019, an additional plaintiff, Robert Fulcher, or Fulcher, filed a substantially identical putative class action complaint

captioned Fulcher v. Aclaris Therapeutics, Inc., et al. in the same court against the same defendants.

On  November  6,  2019,  the  court  consolidated  the  Rosi  and  Fulcher  actions,  or  together,  the  Consolidated  Securities  Action,  and

appointed Fulcher “lead plaintiff” for the putative class. 

                On January 24, 2020, Fulcher filed a consolidated amended complaint in the Consolidated Securities Action, naming two additional
executive officers as defendants, extending the putative class period to August 12, 2019, and adding allegations concerning, among other things,
alleged  statements  and  omissions  throughout  the  putative  class  period  concerning  ESKATA’s  risks,  tolerability  and  effectiveness.    The
defendants’ deadline to answer, move against or otherwise respond to the consolidated amended complaint is March 27, 2020.

We and the other defendants dispute plaintiffs’ claims in the Consolidated Securities Action and intend to defend the matter vigorously.

Stockholder Derivative Action

On November 15, 2019, plaintiff Keith Allred, or Allred, filed a derivative stockholder complaint captioned Allred v. Walker et al. in the
U.S. District Court for the Southern District of New York against certain of our directors and executive officers.  The complaint alleges that the
defendants,  among  other  things,  breached  their  fiduciary  duties  as  directors  and/or  officers  in  connection  with  the  claims  alleged  in  the
Consolidated Securities Action.  The complaint seeks, among other things, unspecified compensatory damages on behalf of our company. 

58

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

On November 25, 2019, an additional plaintiff, Bruce Brown, or Brown, filed a substantially identical complaint captioned Brown v.

Walker et al. in the same court against the same defendants.

                                On  December  12,  2019,  the  court  consolidated  the  Allred  and  Brown  actions  under  the  caption  In  re  Aclaris  Therapeutics,  Inc.
Derivative Litigation, or the Consolidated Derivative Action, and directed that future derivative cases filed in or transferred to the court arising
out  of  substantially  the  same  transactions  or  events  be  similarly  consolidated.    Thereafter,  on  January  11,  2020,  the  court  stayed  –  subject  to
certain conditions – all deadlines in the Consolidated Derivative Action pending resolution of the defendants’ anticipated motion to dismiss the
Consolidated Securities Action.

The defendants dispute plaintiffs’ claims in the Consolidated Derivative Action and intend to defend the matter vigorously.  

Patent Infringement

On October 8, 2019, we, together with Allergan, Inc., filed a patent infringement lawsuit in the U.S. District Court for the District of
Delaware  against  Taro  Pharmaceuticals,  Inc.,  or  Taro,  related  to  an  ANDA  that  Taro  filed  with  the  FDA  to  market  a  generic  version  of
RHOFADE.  The lawsuit claims infringement of U.S. Patent Nos. 7,812,049, 8,420,688, 8,815,929, 9,974,773 and 10,335,391, which are listed
in  the  FDA’s  Approved  Drug  Products  with  Therapeutic  Equivalence  Evaluations,  commonly  known  as  the  Orange  Book,  for
RHOFADE.    We  received  a  Paragraph  IV  Notice  Letter  from  Taro  dated  August  28,  2019,  advising  that  Taro  had  submitted  an  ANDA  to
the FDA seeking approval from the FDA to manufacture and market a generic version of RHOFADE prior to the expiration of the Orange Book-
listed patents. Under our agreement with EPI Health for the purchase of RHOFADE, EPI Health agreed to file a motion to be substituted for us as
a plaintiff party and has agreed to reimburse us for our reasonable fees and expenses so long as we remained a plaintiff party. On December 3,
2019, EPI Health was substituted for us as a plaintiff party.

In addition, from time to time, we are subject to litigation and claims arising in the ordinary course of business but, except as stated
above, we are not currently a party to any material legal proceedings and we are not aware of any pending or threatened legal proceeding against
us that we believe could have a material adverse effect on our business, operating results, cash flows or financial condition.

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

You  should  read  the  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  in  conjunction  with  the
consolidated  financial  statements  and  the  related  notes  to  those  statements  included  later  in  this  Annual  Report.  In  addition  to  historical
financial  information,  the  following  discussion  contains  forward‑looking  statements  that  reflect  our  plans,  estimates,  beliefs  and  expectations
that  involve  risks  and  uncertainties.  Our  actual  results  and  the  timing  of  events  could  differ  materially  from  those  discussed  in  these
forward‑looking  statements.  Factors  that  could  cause  or  contribute  to  these  differences  include  those  discussed  below  and  elsewhere  in  this
Annual Report, particularly in “Item 1A. Risk Factors” and “Special Note Regarding Forward‑Looking Statements.”

Overview

We are a physician-led biopharmaceutical company focused on immuno-inflammatory diseases.  We currently have a pipeline of drug
candidates focused on immuno-inflammatory diseases, as well as one product approved by the U.S. Food and Drug Administration, or FDA, that
we  are  not  currently  distributing,  marketing  or  selling,  and  other  investigational  drug  candidates.  In  September  2019,  we  announced  the
completion of a strategic review of our business, as a result of which we are refocusing our resources on our immuno-inflammatory development
programs.  We  plan  to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further
develop,  obtain  marketing  approval  for  and/or  commercialize  our  drug  candidates  and  ESKATA  (hydrogen  peroxide)  topical  solution,  40%
(w/w), or ESKATA, our non-marketed FDA-approved product.

Since our inception, we have incurred significant operating losses.  Our net loss was $161.4 million for the year ended December 31,
2019 and $132.7 million for the year ended December 31, 2018.  As of December 31, 2019, we had an accumulated deficit of $453.5 million. We
expect to incur significant expenses and operating losses for the foreseeable future as we advance our drug candidates from discovery through
preclinical and clinical development. In addition, our drug candidates, even if they are approved by regulatory agencies for marketing, may not
achieve  commercial  success.    We  may  also  not  be  successful  in  pursuing  strategic  alternatives,  including  identifying  and  consummating
transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize our drug candidates or ESKATA.
Furthermore, we have incurred and expect to continue to incur significant costs associated with operating as a public company, including legal,
accounting, investor relations and other expenses.  As a result, we will need substantial additional funding to support our continuing operations.

We have historically financed our operations primarily with sales of our convertible preferred stock, as well as net proceeds from our
initial public offering, or IPO, in October 2015, and subsequent public offerings of, and a private placement of, our common stock.  In the near
term, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential partnerships
with  other  companies  or  other  strategic  transactions.    We  may  be  unable  to  raise  additional  funds  or  enter  into  such  other  agreements  or
arrangements when needed on commercially acceptable terms, or at all.  If we fail to raise capital or enter into such agreements as, and when,
needed, we may have to significantly delay, scale back or discontinue the development of one or more of our drug candidates. 

License Agreement with Rigel

In  August  2015,  we  entered  into  an  exclusive,  worldwide  license  and  collaboration  agreement  with  Rigel  Pharmaceuticals,  Inc.,  or
Rigel, for the development and commercialization of products containing two specified Janus Kinase, or JAK, inhibitors, ATI-501 and ATI-502,
or  the  Rigel  License  Agreement,  which  we  amended  in  October  2019.    Under  this  agreement,  we  may  develop  these  JAK  inhibitors  for  the
treatment of alopecia areata, or AA, and other dermatological conditions. We paid Rigel an upfront nonrefundable payment of $8.0 million in
2015  and  $4.0  million  upon  the  achievement  of  a  specified  development  milestone  in  2019.  In  addition,  we  have  agreed  to  make  remaining
aggregate  payments  of  up  to  $76.0  million  upon  the  achievement  of  specified  development  milestones,  such  as  clinical  trials  and  regulatory
approvals.    Further,  we  have  agreed  to  pay  up  to  an  additional  $10.5  million  to  Rigel  upon  the  achievement  of  a  second  set  of  development
milestones.  In addition, in connection with the amendment of the agreement in October 2019, we agreed to pay Rigel an amendment fee of $1.5
million  in  three  installments  of  $0.5  million  in  January  2020,  April  2020  and  July  2020,  which  is  included  in  accrued  expenses  on  our
consolidated balance sheet.  With respect to any products we commercialize under the Rigel License Agreement, we will pay Rigel quarterly
tiered royalties on our annual net sales of each product at a high single digit percentage of annual net sales, subject to specified reductions until
the date that all of the patent rights for that product have expired, as determined on a country-by-country and product-by-

product basis or, in specified countries under specified circumstances, 10 years from the first commercial sale of such product.    

The Rigel License Agreement terminates on the date of expiration of all royalty obligations unless earlier terminated by either party for
a material breach. We may also terminate the Rigel License Agreement without cause at any time upon advance written notice to Rigel. Rigel,
after consultation with us, will be responsible for maintaining and prosecuting the patent rights, and we will have final decision-making authority
regarding  such  patent  rights  for  a  product  in  the  United  States  and  the  European  Union.  To  the  extent  that  we  jointly  develop  intellectual
property, we will confer and decide which party will be responsible for filing, prosecuting and maintaining those patent rights. The Rigel License
Agreement  also  establishes  a  joint  steering  committee  composed  of  an  equal  number  of  representatives  for  each  party,  which  will  monitor
progress in the development of products. 

Stock Purchase Agreement with Vixen Pharmaceuticals, Inc. and License Agreement with Columbia University

In March 2016, we entered into a stock purchase agreement, or the Vixen Agreement, with Vixen Pharmaceuticals, Inc., or Vixen, and
JAK1,  LLC,  JAK2,  LLC  and  JAK3,  LLC,  or  together,  the  Selling  Stockholders,  and  Shareholder  Representative  Services  LLC  as  the
representative of the Selling Stockholders.  Pursuant to the Vixen Agreement, we acquired all shares of Vixen’s capital stock from the Selling
Stockholders,  or  the  Vixen  Acquisition.  Following  the  Vixen  Acquisition,  Vixen  became  our  wholly-owned  subsidiary.  Pursuant  to  the  Vixen
Agreement, we paid $0.6 million upfront and issued an aggregate of 159,420 shares of our common stock to the Selling Stockholders. We are
obligated to make annual payments of $0.1 million through March 2022, with such amounts being creditable against specified future payments
that may be paid under the Vixen Agreement.    

Under the Vixen Agreement we are obligated to make aggregate payments of up to $18.0 million to the Selling Stockholders upon the
achievement  of  specified  pre-commercialization  milestones  for  three  products  covered  by  the  Vixen  patent  rights  in  the  United  States,  the
European  Union  and  Japan,  and  aggregate  payments  of  up  to  $22.5  million  upon  the  achievement  of  specified  commercial  milestones  for
products covered by the Vixen patent rights. With respect to any covered products that we commercialize under the Vixen Agreement, we are
obligated to pay low single-digit royalties on net sales, subject to specified reductions, limitations and other adjustments, until the date that all of
the  patent  rights  for  that  product  have  expired,  as  determined  on  a  country-by-country  and  product-by-product  basis  or,  in  specified
circumstances, ten years from the first commercial sale of such product. If we sublicense any of Vixen’s patent rights and know-how acquired
pursuant  to  the  Vixen  Agreement,  we  will  be  obligated  to  pay  a  portion  of  any  consideration  we  receive  from  such  sublicenses  in  specified
circumstances. 

As a result of the Vixen Acquisition, we became party to the Exclusive License Agreement, by and between Vixen and the Trustees of
Columbia  University  in  the  City  of  New  York,  or  Columbia,  dated  as  of  December  31,  2015,  or,  as  amended,  the  Columbia  License
Agreement.  Under the Columbia License Agreement, we are obligated to pay Columbia an annual license fee of $10,000 subject to specified
adjustments  for  patent  expenses  incurred  by  Columbia  and  creditable  against  any  royalties  that  may  be  paid  under  the  Columbia  License
Agreement.  We  are  also  obligated  to  pay  up  to  an  aggregate  of  $11.6  million  upon  the  achievement  of  specified  commercial  milestones,
including  specified  levels  of  net  sales  of  products  covered  by  Columbia  patent  rights  and/or  know-how,  and  royalties  at  a  sub-single-digit
percentage  of  annual  net  sales  of  products  covered  by  Columbia  patent  rights  and/or  know-how,  subject  to  specified  adjustments.  If  we
sublicense any of Columbia’s patent rights and know-how acquired pursuant to the Columbia License Agreement, we will be obligated to pay
Columbia a portion of any consideration received from such sublicenses in specified circumstances.  The royalties, as determined on a country-
by-country and product-by-product basis, are payable until the date that all of the patent rights for that product have expired, the expiration of
any  market  exclusivity  period  granted  by  a  regulatory  body  or,  in  specified  circumstances,  ten  years  from  the  first  commercial  sale  of  such
product.  The Columbia License Agreement terminates on the date of expiration of all royalty obligations thereunder unless earlier terminated by
either party for a material breach, subject to a specified cure period. We may also terminate the Columbia License Agreement without cause at
any time upon advance written notice to Columbia.

Agreement and Plan of Merger with Confluence

In  August  2017,  we  entered  into  an  Agreement  and  Plan  of  Merger,  or  the  Confluence  Agreement,  with  Confluence,  Aclaris  Life
Sciences,  Inc.,  our  wholly-owned  subsidiary,  or  Merger  Sub,  and  Fortis  Advisors  LLC,  as  representative  of  the  equity  holders  of
Confluence.  Pursuant to the terms of the Confluence Agreement, the Merger Sub merged with and into Confluence, with Confluence surviving
as our wholly-owned subsidiary.  We paid $10.3 million in cash and issued 349,527 shares of our common stock with a fair value of $9.7 million
to the Confluence equity holders. 

In  November  2018,  we  achieved  a  development  milestone  specified  in  the  Confluence  Agreement.    The  milestone  payment  to  the
former  Confluence  equity  holders  was  comprised  of  $2.5  million  in  cash  and  253,208  shares  of  our  common  stock  with  a  fair  value  of  $2.2
million.  We also agreed to pay the former Confluence equity holders aggregate remaining contingent consideration of up to $75.0 million, based
upon the achievement of specified regulatory and commercial milestones set forth in the Confluence Agreement.  In addition, we have agreed to
pay  the  former  Confluence  equity  holders  future  royalty  payments  calculated  as  a  low  single-digit  percentage  of  annual  net  sales,  subject  to
specified reductions, limitations and other adjustments, until the date that all of the patent rights for that product have expired, as determined on a
country-by-country  and  product-by-product  basis  or,  in  specified  circumstances,  ten  years  from  the  first  commercial  sale  of  such  product.    In
addition, if we sell, license or transfer any of the intellectual property acquired from Confluence pursuant to the Confluence Agreement to a third
party, we will be obligated to pay the former Confluence equity holders a portion of any incremental consideration (in excess of the development
and milestone payments described above) that we receive from such sale, license or transfer in specified circumstances. 

License, Development and Commercialization Agreement with Cipher Pharmaceuticals Inc.

In  April  2018,  we  entered  into  an  exclusive  license  agreement  with  Cipher  Pharmaceuticals  Inc.,  or  Cipher,  for  the  rights  to  obtain
regulatory approval of and commercialize A-101 40% Topical Solution, which we marketed under the brand name ESKATA in the United States,
in Canada for the treatment of seborrheic keratosis, or the Cipher License Agreement.  We received an upfront payment of $1.0 million upon
signing of the Cipher License Agreement and $0.5 million upon the achievement of a specified regulatory milestone.  In September 2019, we and
Cipher mutually terminated the Cipher License Agreement. 

Asset Purchase Agreement with Allergan

In November 2018, we acquired RHOFADE (oxymetazoline hydrochloride) cream, 1%, or  RHOFADE,  which  included  an  exclusive
license to certain intellectual property for RHOFADE, as well as additional intellectual property, from Allergan Sales, LLC, or Allergan, pursuant
to an asset purchase agreement.    

At the closing of the acquisition, we paid total cash consideration of $66.1 million, consisting of $59.6 million paid to Allergan and $6.5
million placed in escrow. In addition, we agreed to pay Allergan specified royalty payments, ranging from a mid-single digit percentage to a mid-
teen percentage of net sales, subject to specified reductions, limitations and other adjustments. In addition, we agreed to assume the obligation to
pay specified royalties and milestone payments under agreements with Aspect Pharmaceuticals, LLC and Vicept Therapeutics, Inc.  We incurred
an aggregate expense of approximately $0.7 million and $0.2 million related to royalty payments under these agreements during the years ended
December 31, 2019 and 2018, respectively. 

Asset Purchase Agreement with EPI Health

In  October  2019,  we  entered  into  an  asset  purchase  agreement  with  EPI  Health,  LLC,  or  EPI  Health,  pursuant  to  which  we  sold  the

worldwide rights to RHOFADE, which included the assignment of certain licenses for related intellectual property assets, or the Disposition. 

Pursuant to the asset purchase agreement,  EPI Health paid us an upfront payment of $35.0 million, $1.75 million of which was placed
in escrow, and $0.2 million for inventory.  In addition, EPI Health has agreed to pay us (i) potential sales milestone payments of up to $20.0
million in the aggregate upon the achievement of specified levels of net sales of products covered by the agreement, (ii) a specified high single-
digit royalty calculated as a percentage of net sales, on a product-by-product and country-by-country basis, until the date that the patent rights
related to a particular product, such as RHOFADE, have expired, provided, that with respect to sales of RHOFADE in any territory outside of the
United

63

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

States, such royalty shall be paid on a country-by-country basis until the date that the RHOFADE patent rights in the particular country have
expired  or,  if  later,  10  years  from  the  date  of  the  first  commercial  sale  of  RHOFADE  in  such  country  and    (iii)  25%  of  any  upfront,  license,
milestone, maintenance or fixed payment received by EPI Health in connection with any license or sublicense of the assets transferred in the
Disposition  in  any  territory  outside  of  the  United  States,  subject  to  specified  exceptions.    In  addition,  EPI  Health  has  agreed  to  assume  our
obligation  to  pay  specified  royalties  and  milestone  payments  under  our  existing  agreements  with  Allergan,  Aspect  Pharmaceuticals,  LLC  and
Vicept Therapeutics, Inc.

Other Third-Party Agreements

Under  an  assignment  agreement,  pursuant  to  which  we  acquired  intellectual  property,  we  have  agreed  to  pay  royalties  on  sales  of
ESKATA and related products at rates ranging in low single-digit percentages of net sales, as defined in the agreement.  Under this assignment
agreement,  we  paid  $0.2  million  in  connection  with  a  specified  development  milestone,  and  there  are  no  remaining  milestone  payment
obligations. 

In connection with the assignment agreement, we also entered into a finder’s services agreement under which we have made aggregate
milestone payments of $3.0 million upon the achievement of specified pre-commercialization milestones, such as clinical trials and regulatory
approvals, and commercial milestones as described in the agreement.  We have also agreed to make an additional payment of $3.0 million upon
the achievement of a specified commercial milestone.  In addition, we have agreed to pay royalties on sales of ESKATA and related products at a
low single-digit percentage of net sales, as defined in the agreement. 

In  August  2019,  we  voluntarily  discontinued  the  commercialization  of  ESKATA  in  the  United  States  and  withdrew  the  marketing

authorizations we had previously received for the product in all countries outside of the United States.

Components of Our Results of Operations

Revenue

Product Sales, net

We  sold  RHOFADE  in  the  United  States  during  the  years  ended  December  31,  2019  and  2018.   We  relied  on  Allergan  to  distribute
RHOFADE  on  our  behalf  pursuant  to  the  terms  of  a  transition  services  agreement.   We  sold  RHOFADE  to  wholesalers  in  the  United  States,
which, in turn, distributed it to pharmacies that ultimately filled patient prescriptions.  We also entered into, or were subject to, arrangements with
third-party payors, including pharmacy benefit managers and government agencies, as well as group purchasing organizations, or GPOs, which
provided for government mandated or privately negotiated rebates, chargebacks, and discounts with respect to the purchase of RHOFADE.  We
never sold RHOFADE outside of the United States.  We sold the worldwide rights to RHOFADE to EPI Health in October 2019. 

During the years ended December 31, 2019 and 2018, we sold ESKATA to one wholesaler, McKesson Specialty Care Distribution, or
McKesson,  which  in  turn  resold  ESKATA  to  health  care  providers.    We  also  entered  into  agreements  with  two  GPOs  that  provided  for
administrative fees and discounted pricing in the form of volume-based rebates and chargebacks.  We never sold ESKATA outside of the United
States.  We discontinued sales of ESKATA in the United States in August 2019.  

Product sales, net has been reclassified to discontinued operations for all periods presented. 

Contract Research

We  earn  revenue  from  the  provision  of  laboratory  services  to  clients  through  Confluence,  our  wholly-owned  subsidiary.    Contract
research revenue is generally evidenced by contracts with clients which are on an agreed upon fixed-price, fee-for-service basis and are generally
billed on a monthly basis in arrears for services rendered. 

64

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

We have also received revenue from grants under the Small Business Innovation Research program of the National Institutes of Health,
or NIH.  During the year ended December 31, 2018, we had two active grants from NIH related to early-stage research.  As of December 31,
2019, there were no remaining funds available to us under the grants. 

Cost of Revenue

Cost  of  revenue  consists  of  the  costs  incurred  in  connection  with  the  provision  of  contract  research  services  to  our  clients  through

Confluence.  Cost of revenue primarily includes:

·
·
·
·
·

employee-related expenses, which include salaries, benefits and stock-based compensation;
outsourced professional scientific services;
depreciation of laboratory equipment;
facility-related costs; and
laboratory materials and supplies used to support the services provided.

Research and Development Expenses

Research  and  development  expenses  consist  of  expenses  incurred  in  connection  with  the  discovery  and  development  of  our  drug

candidates. These expenses primarily include:

·

expenses incurred under agreements with contract research organizations, or CROs, as well as investigative sites and consultants
that conduct our clinical trials and preclinical studies;

· manufacturing scale-up expenses and the cost of acquiring and manufacturing active pharmaceutical ingredients and preclinical and

clinical trial materials;
outsourced professional scientific development services;

·
· medical affairs expenses related to our drug candidates, including investigator-initiated studies;
employee-related expenses, which include salaries, benefits and stock-based compensation;
·
depreciation of manufacturing equipment;
·
payments made under agreements with third parties under which we have acquired or licensed intellectual property;
·
expenses relating to regulatory activities, including filing fees paid to regulatory agencies;
·
laboratory materials and supplies used to support our research activities; and
·
non-cash charges for changes in the fair value of contingent consideration.
·

Research  and  development  activities  are  central  to  our  business  model.    Drug  candidates  in  later  stages  of  clinical  development
generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of
later-stage  clinical  trials.    We  expect  to  continue  to  incur  research  and  development  expenses  in  the  near  term  as  we  continue  the  clinical
development of ATI-450 as a potential treatment for rheumatoid arthritis and other immuno-inflammatory diseases, continue the development of
our  preclinical  compounds,  and  continue  to  identify,  research  and  develop  additional  drug  candidates.    Our  direct  research  and  development
expenses primarily consist of external costs including fees paid to CROs, consultants, investigator sites, regulatory agencies and third parties that
manufacture  our  preclinical  and  clinical  trial  materials,  and  are  tracked  on  a  program-by-program  basis.   We  do  not  allocate  personnel  costs,
facilities or other indirect expenses, to specific research and development programs. 

The successful development of our drug candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature,
timing and costs of the efforts that will be necessary to complete the remainder of the development of, or when, if ever, material net cash inflows
may commence from any of our drug candidates. This uncertainty is due to the numerous risks and uncertainties associated with the duration and
cost of clinical trials, which vary significantly over the life of a project as a result of many factors, including:

·
·
·
·
·

the number of clinical sites included in the trials;
the length of time required to enroll suitable subjects;
the number of subjects that ultimately participate in the trials;
the number of doses subjects receive;
the duration of subject follow-up; and

65

 
 
 
 
 
 
 
 
 
 
Table of Contents

·

the results of our clinical trials.

Our expenditures are subject to additional uncertainties, including the preparation of regulatory filings for our drug candidates, and the
expense of filing, prosecuting, defending and enforcing any patent claims or other intellectual property rights.  We may obtain unexpected results
from our clinical trials.  We may elect to discontinue, delay or modify clinical trials of some drug candidates or focus on others.  A change in the
outcome of any of these variables with respect to the development of a drug candidate could mean a significant change in the costs and timing
associated with the development of that drug candidate.  For example, if the FDA or other regulatory authorities were to require us to conduct
clinical trials beyond those that we currently anticipate, or if we experience significant delays in enrollment in any of our clinical trials, we could
be required to expend significant additional financial resources and time on the completion of clinical development. 

Sales and Marketing Expenses

Sales  and  marketing  expenses  primarily  consist  of  market  research  activities  related  to  A-101  45%  Topical  Solution  and  our  JAK

inhibitors. 

General and Administrative Expenses

General and administrative expenses consist principally of salaries and related costs for personnel in executive, administrative, finance,
investor relations and legal functions, including stock-based compensation, travel expenses and recruiting expenses.  General and administrative
expenses also include facility-related costs, patent filing and prosecution costs, professional fees for legal, auditing and tax services, insurance
costs,  as  well  as  payments  made  under  a  terminated  related  party  sublease  agreement  and  milestone  payments  under  our  finder’s  services
agreement.  We anticipate that we will incur increased director and officer insurance premiums and legal expenses associated with defending the
current lawsuits described in this report.    

Other Income (Expense), net

Other income (expense), net consists of interest earned on our cash, cash equivalents and marketable securities, interest expense, and

gains and losses on transactions denominated in foreign currencies.

Critical Accounting Policies and Significant Judgments and Estimates

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

While our significant accounting policies are described in more detail in the notes to our consolidated financial statements appearing
elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are those most critical to the judgments and
estimates used in the preparation of our consolidated financial statements. 

Revenue Recognition

We  account  for  revenue  in  accordance  with  Accounting  Standards  Codification,  or  ASC,  Topic  606,  Revenue  from  Contracts  with
Customers.    Under  ASC  Topic  606,  revenue  is  recognized  when  a  customer  obtains  control  of  promised  goods  or  services  in  an  amount  that
reflects the consideration to which we expect to be entitled in exchange for those goods or services. 

To determine revenue recognition in accordance with ASC Topic 606, we perform 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) performance obligations are satisfied.  We recognize revenue
when collection of the consideration we are entitled to under a contract with a customer is probable.  At contract inception, we assess the goods
or  services  promised  within  a  contract  with  a  customer  to  identify  the  performance  obligations,  and  to  determine  if  they  are  distinct.    We
recognize  revenue  that  is  allocated  to  each  distinct  performance  obligation  when  (or  as)  that  performance  obligation  is  satisfied.    We  only
recognize revenue when collection of the consideration we are entitled to under a contract with a customer is probable.

Product Sales, net

We recognized revenue from product sales at the point the customer obtained control, which generally occurred upon delivery.  We also
included estimates of variable consideration in the same period revenue was recognized.  Components of variable consideration included trade
discounts  and  allowances,  product  returns,  government  rebates,  discounts  and  rebates,  other  incentives  such  as  patient  co-pay  assistance,  and
other  fee  for  service  amounts.    Variable  consideration  was  recorded  on  the  consolidated  balance  sheet  as  either  a  reduction  of  accounts
receivable,  if  payable  to  a  customer,  or  as  a  current  liability,  if  payable  to  a  third-party  other  than  a  customer.    We  considered  all  relevant
information  when  estimating  variable  consideration  such  as  contractual  and  statutory  requirements,  specific  known  market  events  and  trends,
industry  data  and  forecasted  customer  buying  and  payment  patterns.    The  amount  of  net  revenue  that  can  be  recognized  is  constrained  by
estimates  of  variable  consideration  which  are  included  in  the  transaction  price.    Payment  terms  with  customers  did  not  exceed  one  year  and,
therefore,  we  did  not  account  for  a  financing  component  in  our  arrangements.   We  expensed  incremental  costs  of  obtaining  a  contract  with  a
customer, including sales commissions, when incurred as the period of benefit was less than one year.

Trade  Discounts  and  Allowances  -  We  provided  customers  with  trade  discounts,  rebates,  allowances  and/or  other  incentives.    We

recorded estimates for these items as a reduction of revenue in the same period the revenue was recognized. 

Government  and  Payor  Rebates  –  We  contracted  with,  or  were  subject  to  arrangements  with,  certain  third-party  payors,  including
pharmacy benefit managers and government agencies, for the payment of rebates with respect to utilization of our commercial products.  We also
entered into agreements with GPOs that provided for administrative fees and discounted pricing in the form of volume-based rebates.  We were
also  subject  to  discount  and  rebate  obligations  under  state  Medicaid  programs  and  Medicare.   We  recorded  estimates  for  these  discounts  and
rebates as a reduction of revenue in the same period the revenue was recognized. 

67

 
 
 
 
 
 
 
 
 
 
Table of Contents

Other  Incentives  –  We  maintained  a  co-pay  assistance  program  which  was  intended  to  provide  financial  assistance  to  qualified
commercially-insured patients with prescription drug co-payments required by third-party payors.  We estimated and recorded accruals for these
incentives as a reduction of revenue in the period the revenue was recognized.   Our estimated amounts for co-pay assistance were based upon
the number of claims and the cost per claim that we expected to receive associated with product that had been sold to customers but remained in
the distribution channel at the end of each reporting period. 

Product Returns - Consistent with industry practice, we have a product returns policy for RHOFADE which may provide customers a
right of return for product purchased within a specified period prior to and subsequent to the product’s expiration date.  The right of return lapses
upon shipment of the product to a patient.  We recorded an estimate for the amount of product which may be returned as a reduction of revenue
in the period the related revenue was recognized.  Our estimates for product returns were based upon available industry data and our own sales
information,  including  visibility  into  the  inventory  remaining  in  the  distribution  channel.   There  is  no  return  liability  associated  with  sales  of
ESKATA as we had a no returns policy for ESKATA when we commercialized it. 

Contract Research

Revenue related to laboratory services is generally recognized as the laboratory services are performed, based upon the rates specified in
the  contracts.    Under  ASC  Topic  606,  we  elected  to  apply  the  “right  to  invoice”  practical  expedient  when  recognizing  contract  research
revenue.  We recognize contract research revenue in the amount to which we have the right to invoice. 

We  recognize  revenue  related  to  grants  as  amounts  become  reimbursable  under  each  grant,  which  is  generally  when  research  is

performed, and the related costs are incurred. 

Other Revenue

Licenses  of  Intellectual  Property  –  We  recognize  revenue  received  from  non-refundable,  upfront  fees  related  to  the  licensing  of
intellectual  property  when  the  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the
arrangement, the license has been transferred to the customer, and the customer is able to use and benefit from the license. 

Milestone Payments – At the inception of each arrangement that includes milestone payments, we evaluate whether the milestones are
considered probable of being reached and estimate the amount to be included in the transaction price using the most likely amount method.  If it
is probable that a significant revenue reversal would not occur, the associated milestone value is included in the amount allocated to the license
of intellectual property.  Milestone payments that are not within our control or the control of the customer, such as regulatory approvals, are not
considered probable of being achieved until those approvals are received.

Inventory

Inventory  included  the  third-party  cost  of  manufacturing  and  assembly  of  the  finished  product  forms  of  ESKATA  and  RHOFADE,
quality control and other overhead costs.  Inventory is stated at the lower of cost or net realizable value.  Inventory is adjusted for short-dated,
unmarketable  inventory  equal  to  the  difference  between  the  cost  of  inventory  and  the  estimated  value  based  upon  assumptions  about  future
demand and market conditions.  Inventory was comprised primarily of finished goods and has been reclassified to discontinued operations for all
periods presented.

Intangible Assets

Our  intangible  assets  include  both  definite-lived  and  indefinite-lived  assets.    Definite-lived  intangible  assets  are  amortized  over  their
estimated useful life based on the pattern over which the intangible assets are consumed or otherwise used up. If that pattern cannot be reliably
determined,  the  straight-line  method  of  amortization  is  used.    Our  definite-lived  intangible  assets  consist  of  a  research  technology  platform
acquired through the acquisition of Confluence.  Prior to the disposition in 2019, definite-lived intangible assets also included the intellectual
property rights related to RHOFADE.  Our indefinite-lived intangible assets consist of an in-process research and development, or IPR&D, drug
candidate acquired through the acquisition of Confluence.  IPR&D assets are considered indefinite-lived until the completion or abandonment of
the associated research and development efforts.  The cost of IPR&D assets is either amortized over their estimated useful life beginning when
the  underlying  drug  candidate  is  approved  and  launched  commercially,  or  expensed  immediately  if  development  of  the  drug  candidate  is
abandoned. 

Definite-lived intangible assets are tested for impairment when events or changes in circumstances indicate that the carrying value of
the  asset  may  not  be  recoverable.    Indefinite-lived  intangible  assets  are  tested  for  impairment  at  least  annually,  which  we  perform  during  the
fourth quarter, or when indicators of an impairment are present.  We recognize an impairment loss when and to the extent that the estimated fair
value of an indefinite-lived intangible asset is less than its carrying value. 

During the year ended December 31, 2019, we performed an impairment analysis of the RHOFADE intangible asset due to our decision
to discontinue commercial operations and actively seek a commercialization partner for RHOFADE.  Our impairment analysis, which primarily
utilized  a  third-party  indication  of  fair  value,  resulted  in  a  fair  value  for  the  RHOFADE  intangible  asset  which  was  less  than  its  carrying
value.  As a result, we recorded an impairment charge of $27.6 million to adjust the carrying value of the RHOFADE intangible asset to its net
realizable value. 

Goodwill

Goodwill is not amortized, but rather is subject to testing for impairment at least annually, which we perform either during the fourth
quarter or when indicators of an impairment are present.  We consider each of our operating segments, therapeutics and contract research, to be a
reporting unit since this is the lowest level for which discrete financial information is available.  We attributed the full amount of the goodwill in
connection with the acquisition of Confluence, or $18.5 million, to our therapeutics segment.  We perform an impairment test annually which is a
qualitative  assessment  based  upon  current  facts  and  circumstances  related  to  operations  of  the  therapeutics  segment.    If  our  qualitative
assessment indicates an impairment may be present, we would perform the required quantitative analysis and an impairment charge would be
recognized to the extent that the estimated fair value of the reporting unit is less than its carrying amount.  However, any loss recognized would
not exceed the total amount of goodwill allocated to that reporting unit. 

During  the  year  ended  December  31,  2019,  we  performed  an  impairment  analysis  due  to  the  decline  in  our  stock  price,  which  was
considered a triggering event to evaluate goodwill for impairment.  Our impairment analysis, which utilized a market approach, noted that our
stock price, including a reasonable control premium, resulted in a fair value for the therapeutics reporting unit which was less than its carrying
value.  As a result, we recorded an impairment charge of $18.5 million, the full balance of goodwill. 

Leases

Leases represent a company’s right to use an underlying asset and a corresponding obligation to make payments to a lessor for the right
to use those assets.  We evaluate leases at their inception to determine if they are an operating lease or a finance lease.  A lease is accounted for as
a finance lease if it meets one of the following five criteria: the lease has a purchase option that is reasonably certain of being exercised, the
present  value  of  the  future  cash  flows  are  substantially  all  of  the  fair  market  value  of  the  underlying  asset,  the  lease  term  is  for  a  significant
portion of the remaining economic life of the underlying asset, the title to the underlying asset transfers at the end of the lease term, or if the
underlying asset is of such a specialized nature that it is expected to have no alternative uses to the lessor at the end of the term.  Leases that do
not meet the finance lease criteria are accounted for as an operating lease. 

We recognize assets and liabilities for leases at their inception based upon the present value of all payments due under the lease.  We use
an implicit interest rate to determine the present value of finance leases, and our incremental borrowing rate to determine the present value of
operating leases.  We determine incremental borrowing rates by

69

 
 
 
 
 
 
 
 
 
Table of Contents

referencing collateralized borrowing rates for debt instruments with terms similar to the respective lease.  We recognize expense for operating
and finance leases on a straight-line basis over the term of each lease, and interest expense related to finance leases is recognized over the lease
term based on the effective interest method.  We include estimates for any residual value guarantee obligations under our leases in lease liabilities
recorded on our consolidated balance sheet. 

Right-of-use assets are included in other assets and property and equipment, net on our consolidated balance sheet for operating and
finance  leases,  respectively.    Obligations  for  lease  payments  are  included  in  current  portion  of  lease  liabilities  and  other  liabilities  on  our
consolidated balance sheet for both operating and finance leases. 

Contingent Consideration

We  initially  recorded  the  contingent  consideration  related  to  future  potential  payments  based  upon  the  achievement  of  specified
development,  regulatory  and  commercial  milestones,  resulting  from  the  acquisition  of  Confluence,  at  its  estimated  fair  value  on  the  date  of
acquisition.  Changes in fair value reflect new information about the likelihood of the payment of the contingent consideration and the passage of
time.  For example, if the timing of the development of an acquired drug candidate, or the size of potential commercial opportunities related to an
acquired drug, differ from our assumptions, then the fair value of contingent consideration would be adjusted accordingly.  Future changes in the
fair value of the contingent consideration, if any, will be recorded as income or expense in our consolidated statement of operations. 

During  the  year  ended  December  31,  2019,  we  updated  our  assumptions  for  contingent  consideration  related  to  the  acquisition  of

Confluence as a result of the filing of an IND for ATI-450, which resulted in a charge of $0.7 million.

Research and Development Expenses

As  part  of  the  process  of  preparing  our  consolidated  financial  statements,  we  are  required  to  estimate  our  research  and  development
expenses.  This process involves reviewing open contracts and purchase orders, communicating with our applicable personnel to identify services
that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we
have  not  yet  been  invoiced  or  otherwise  notified  of  actual  costs.  The  majority  of  our  preclinical  development  activities  and  clinical  trials  are
performed  pursuant  to  quotes  and  contracts  with  multiple  vendors,  including  research  institutions  and  CROs,  that  conduct  and  manage  such
activities  on  our  behalf.    Many  of  the  contracts  with  our  vendors  require  advance  payments;  while  others  invoice  us  in  arrears  for  services
performed, or on a pre-determined schedule, or upon the successful enrollment of subjects, or when contractual milestones are met.  We record
expenses  for  preclinical  development  activities  and  clinical  trials  based  upon  estimates  of  the  total  cost  of  the  services  to  be  provided  by  the
vendor and the time period over which the vendor is to perform those services.  Estimates of research and development expenses included in our
consolidated  financial  statements  are  based  on  facts  and  circumstances  known  to  us  at  that  time.  The  financial  terms  of  our  agreements  are
subject to negotiation, vary from contract to contract, and may result in uneven payment flows.  There may be times when payments made to a
vendor exceed the level of services provided, resulting in a prepayment for work to be performed.  We may confirm the accuracy of our estimates
with the service providers, or make adjustments to our estimates based upon new or updated facts and circumstances, as necessary.  For example,
if the timing and/or cost of services to be performed is materially different from our previous estimates, we would make a prospective adjustment
for the change in our estimates in the period in which we become aware of the new cost and/or timing. Although we do not expect our estimates
to be materially different from actual amounts incurred, our understanding of the status and timing of services performed relative to the actual
status and timing of services performed may vary and may result in reporting amounts that are too high or too low in any particular period.  To
date, we have not made any material adjustments to our estimates of research and development expenses. 

Stock-Based Compensation

We measure the compensation expense of stock-based awards granted to employees and directors using the grant date fair value of the
award.    We  have  issued  stock  options  and  restricted  stock  unit,  or  RSU,  awards  with  service-based  vesting  conditions,  as  well  as  with
performance-based  vesting  conditions.    We  have  not  issued  awards  that  include  market-based  conditions.    For  service-based  awards,  we
recognize  stock-based  compensation  expense  on  a  straight-line  basis  over  the  requisite  service  period.    For  performance-based  awards,  we
recognize stock-based compensation expense on a straight-line basis over the requisite service period beginning in the period that it becomes
probable the performance conditions will occur.  At each balance sheet date, we evaluate whether any performance conditions related to a

70

 
 
 
 
 
 
 
 
Table of Contents

performance-based  award  have  changed.   The  effect  of  any  change  in  performance  conditions  would  be  recognized  as  a  cumulative  catch-up
adjustment  in  the  period  such  change  occurs,  and  any  remaining  unrecognized  compensation  expense  would  be  recognized  on  a  straight-line
basis over the remaining requisite service period.  The impact of forfeitures is recognized in the period in which they occur. 

We  initially  measure  the  compensation  expense  of  stock-based  awards  granted  to  consultants  using  the  grant  date  fair  value  of  the
award.  We recognize compensation expense over the period during which services are rendered by the consultant.  At the end of each financial
reporting period prior to the completion of services being rendered, we re-measure the compensation expense related to these awards using the
then current fair value of our common stock for RSUs, or based upon updated assumptions in the Black-Scholes option-pricing model for stock
option awards. 

We estimate the fair value of each stock option grant using the Black-Scholes option-pricing model.  We estimate expected volatility
based on historical volatility of a set of peer companies, which are publicly traded, and we expect to continue to do so until we have adequate
historical data regarding the volatility of our own publicly-traded stock price.  The expected term of our stock options has been determined using
the “simplified” method for awards that qualify as “plain vanilla” options. The expected term of stock options we granted to non-employees is
equal to the contractual term of the option award.  The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect
at the time of grant of the award for time periods approximately equal to the expected term of the award.  We use an expected dividend yield of
zero because we have not paid cash dividends to date, and have no intention of paying cash dividends in the future.  Prior to our IPO, we valued
our  common  stock  using  a  hybrid  method  which  used  market  approaches  to  estimate  our  enterprise  value.    The  hybrid  method  used  was  a
probability-weighted expected return method which was a scenario-based methodology that estimated the fair value of our common stock based
upon an analysis of future values for the company assuming various outcomes.  The hybrid method used calculated equity values using an option
pricing model in one or more of scenarios, and also considered the rights of each class of stock.

The fair value of each RSU is measured using the closing price of our common stock on the date of grant.

Income Taxes

Since our inception, we have not recorded U.S. federal or state income tax benefits for the net operating losses we have incurred in each

year or for our earned research and development tax credits, due to our uncertainty of realizing a benefit from those items.

Contract research revenue was $4.2 million and $4.7 million for the years ended December 31, 2019 and 2018, respectively, and was
comprised primarily of fees earned from the provision of laboratory services to clients through Confluence.  Other revenue for the year ended
December 31, 2018 related to the Cipher License Agreement and consisted of an upfront payment of $1.0 million, and $0.5 million earned upon
the  achievement  of  a  specified  regulatory  milestone.    Revenue  from  sales  of  ESKATA  and  RHOFADE  has  been  reclassified  to  discontinued
operations for all periods presented (see Note 18 to the consolidated financial statements included in this report for more information). 

Cost of Revenue

Cost  of  revenue  was  $4.1  million  and  $4.3  million  for  the  years  ended  December  31,  2019  and  2018,  respectively,  and  related  to
providing laboratory services to our clients through Confluence.  Cost of revenue for sales of ESKATA and RHOFADE has been reclassified to
discontinued  operations  for  all  periods  presented  (see  Note  18  to  the  consolidated  financial  statements  included  in  this  report  for  more

Expenses related to A-101 45% Topical Solution increased primarily due to our two pivotal Phase 3 clinical trials, which were initiated
during the third quarter of 2018 and were completed in September 2019 and October 2019, respectively. Development expenses related to our
JAK inhibitors decreased primarily as a result of several Phase 2 clinical trials of ATI-501 and ATI-502 which were completed during the year
ended December 31, 2019.  The increase in expenses for ATI-450 resulted primarily from preclinical development activities as well as a Phase 1
clinical  trial,  which  was  initiated  and  near  completion  during  the  year  ended  December  31,  2019.    The  increase  in  personnel  expenses  was
primarily the result of increased headcount prior to our restructuring.  The decrease in stock-based compensation expense was primarily the result
of forfeitures by certain employees during 2019.  Restructuring expenses primarily included the cost of termination benefits given to employees
that  were  involuntarily  terminated  during  the  year  ended  December  31,  2019.    Milestones  and  licensing  expenses  consisted  of  $4.0  million
related to the achievement of a development milestone under the Rigel License Agreement, as well as $1.5 million we agreed to pay to Rigel in
connection with the amendment of the agreement.  The change in contingent consideration was the result of updates to our assumptions related to
drug discovery research on our soft-JAK inhibitors, which progressed more quickly than we had originally planned. Other research expenses,
which  primarily  included  expenses  for  medical  affairs  activities  and  drug  discovery,  decreased  primarily  as  a  result  of  lower  medical  affairs
activities during the year ended December 31, 2019.  Expenses related to ESKATA primarily consisted of stability testing.  Expenses related to
ESKATA  for  post-NDA  approval  activities  have  been  reclassified  to  discontinued  operations  for  all  periods  presented  (see  Note  18  to  the
consolidated financial statements included in this report for more information).

Personnel  and  stock-based  compensation  expenses  increased  due  to  increased  headcount  prior  to  our  restructuring.    Restructuring
expenses  primarily  include  the  costs  of  termination  benefits  given  to  employees  that  were  involuntarily  terminated  during  the  year  ended
December  31,  2019.    Professional  and  legal  fees  included  accounting,  legal,  investor  relations  and  corporate  communication  costs,  as  well  as
legal  fees  related  to  patents  and  business  development.   The  decrease  in  professional  and  legal  fees  was  primarily  related  to  lower  corporate
communications costs as well as lower legal costs incurred related to patents.  Facility and support services included general office expenses and
information technology costs, which increased due to our new office and laboratory facility in St. Louis, which we moved into during 2019, as
well as increased headcount prior to our restructuring.  Other general and administrative expenses included insurance, travel costs, depreciation
and other miscellaneous expenses. 

Goodwill Impairment

During the year ended December 31, 2019, we performed an impairment analysis due to the decline in our stock price.  Our impairment
analysis noted that our stock price, including a reasonable control premium, resulted in a fair value for the therapeutics reporting unit which was
less than its carrying value.  As a result, we recorded an impairment charge of $18.5 million writing off the full balance of goodwill. 

Amortization of Definite-Lived Intangible

Amortization  expense  related  to  the  intangible  asset  for  RHOFADE  intellectual  property  has  been  reclassified  to  discontinued

operations for all periods presented (see Note 18 to the consolidated financial statements included in this report for more information).  

Other Income (Expense), net

The $5.2 million decrease in other income (expense), net was primarily due to interest expense incurred on our debt with Oxford, which

we borrowed in October 2018.  We repaid the debt in full in October 2019.

Expenses related to A-101 45% Topical Solution increased primarily due to the initiation of Phase 3 clinical trials for the treatment of
common  warts  during  the  third  quarter  of  2018.    Development  expenses  for  our  JAK  inhibitors  increased  due  to  continued  growth  in  both
preclinical  and  clinical  trial  expenses  as  we  continued  to  conduct  multiple  Phase  2  clinical  trials  of  ATI-501  and  ATI-502.    Development
expenses for ATI-450 increased as we performed IND-enabling preclinical studies and manufacturing scale-up activities in preparation for the
initiation  of  clinical  trials.   The  increase  in  personnel  expenses  was  primarily  the  result  of  increased  headcount.   The  increase  in  stock-based
compensation expense was primarily the result of new awards granted during 2018.  The change in contingent consideration was the result of
updates to our assumptions related to our soft-JAK inhibitors that reflected the achievement of a specified development milestone in November
2018 under the Confluence Agreement.  Other research expenses primarily included expenses for medical affairs activities, and expenses related
to drug discovery performed by Confluence, which we acquired in August 2017; we did not incur similar drug discovery expenses prior to that
acquisition.  The increase in other research expenses was also driven by expenses related to our ITK inhibitor.  Expenses related to ESKATA
primarily  consisted  of  stability  testing  and  regulatory  costs.   The  decrease  in  expenses  related  to  ESKATA  primarily  related  to  the  regulatory
costs associated with the filing of the NDA, which occurred during the year ended December 31, 2017.  Expenses related to ESKATA for post-
NDA approval activities have been reclassified to discontinued operations for all periods presented (see Note 18 to the consolidated financial
statements included in this report for more information).

Personnel and stock-based compensation expenses increased due to increased headcount as we expanded our operations.  Professional
and  legal  fees  included  accounting,  legal  and  investor  relations  costs  associated  with  being  a  public  company,  as  well  as  legal  fees  related  to
patents.    The  increase  in  professional  and  legal  fees  was  related  to  legal  and  consulting  expenses  associated  with  business  development
activities.    Facility  and  support  services  included  general  office  expenses  and  information  technology  costs  which  were  higher  due  to  our
increased headcount as well as the relocation of our headquarters during the year ended December 31, 2018.  The milestone payment of $1.0
million  in  the  year  ended  December  31,  2017  was  made  upon  the  achievement  of  specified  regulatory  milestones  pursuant  to  our  Finder’s
Services Agreement with KPT Consulting, LLC.  Other general and administrative expenses included insurance, travel costs, depreciation and
other miscellaneous expenses.

Other Income, net

The $0.6 million increase in other income, net was primarily due to higher invested balances of marketable securities as a result of funds

received from our financing transactions in 2017 and 2018, as well as higher yields on those invested balances. 

Benefit from Income Taxes

Benefit from income taxes was $1.8 million for the year ended December 31, 2017 and was comprised primarily of the revaluation of

our deferred tax assets, net resulting from the Tax Cuts and Jobs Act of 2017, which was enacted on December 22, 2017. 

Liquidity and Capital Resources

Since our inception, we have incurred net losses and negative cash flows from our operations.  Prior to our acquisition of Confluence in
August 2017, we did not generate any revenue.  We have financed our operations over the last several years primarily through sales of our equity
securities in public offerings and a private placement transaction, as well as debt financing that has since been repaid in full. We may engage in
additional  debt  and  equity  financing  transactions  in  order  to  raise  additional  funds.    In  addition,  to  the  extent  we  are  able  to  consummate
transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize our drug candidates or ESKATA,
we may receive upfront payments, milestone payments or royalties from such arrangements that would increase our liquidity. 

As  of  December  31,  2019,  we  had  cash,  cash  equivalents  and  marketable  securities  of  $75.0  million.    Cash  in  excess  of  immediate

requirements is invested in accordance with our investment policy, primarily with a view towards liquidity and capital preservation.

We  currently  have  no  ongoing  material  financing  commitments,  such  as  lines  of  credit  or  guarantees,  that  are  expected  to  affect  our
liquidity  over  the  next  five  years,  other  than  sublease  obligations,  capital  lease  obligations  and  contingent  obligations  under  acquisition  and
intellectual property licensing agreements, which are summarized below under “Contractual Obligations and Commitments.”  

At-The-Market Facility

In November 2016, we entered into a sales agreement with Cowen and Company, LLC, or Cowen, pursuant to which Cowen acted as
our  agent  in  connection  with  sales  of  our  common  stock  from  time  to  time  under  an  “at-the-market”  equity  facility.    In  April  2017,  we  sold
635,000  shares  of  common  stock  at  a  weighted  average  price  per  share  of  $31.50,  for  aggregate  gross  proceeds  of  $19.3  million.    We  paid
underwriting discounts and commissions of $0.6 million, and also incurred expenses of $0.1 million in connection with this sale.  In October
2018, we terminated the at-the-market sales agreement with Cowen without having sold any additional shares of common stock. 

August 2017 Public Offering

In August 2017, we closed our follow-on public offering in which we sold 3,747,602 shares of common stock at a price to the public of
$23.02 per share, for aggregate gross proceeds of $86.3 million. We paid underwriting discounts and commissions of $5.2 million, and we also
incurred  expenses  of  $0.2  million  in  connection  with  the  offering.    As  a  result,  the  net  offering  proceeds  received  by  us,  after  deducting
underwriting discounts, commissions and offering expenses, were $80.9 million. 

October 2018 Public Offering

In October 2018, we closed a public offering in which we sold 9,941,750 shares of common stock at a price to the public of $10.75 per
share, for aggregate gross proceeds of $106.9 million.  We paid underwriting discounts and commissions of $6.4 million to the underwriters, and
we  incurred  expenses  of  $0.3  million  in  connection  with  the  offering.   As  a  result,  the  net  offering  proceeds  received  by  us,  after  deducting
underwriting discounts, commissions and offering expenses, were $100.2 million. 

Loan and Security Agreement with Oxford 

In October 2018, we entered into a loan and security agreement, or the Loan Agreement, with Oxford Finance LLC, or Oxford. The
Loan Agreement provided for up to $65.0 million in term loans.  Of the $65.0 million, we borrowed $30.0 million in October 2018.  The Loan
Agreement provided for interest only payments through the payment date immediately prior to November 1, 2021, followed by 24 consecutive
equal monthly payments of principal and interest in arrears starting on November 1, 2021 and continuing through the maturity date of October 1,
2023.  The Loan Agreement provided for an annual interest rate equal to the greater of (i) 8.35% and (ii) the 30-day U.S. LIBOR rate reported in
The  Wall  Street  Journal  on  the  last  business  day  of  the  month  that  immediately  preceded  the  month  in  which  the  interest  was  to  accrue  plus
6.25%. The Loan Agreement also provided for a final payment equal to 5.75% of the original principal amount of the term loans drawn. 

We  had  the  option  to  prepay  the  outstanding  balance  of  the  term  loans  in  full,  subject  to  a  prepayment  fee  of  (i)  3%  of  the  original
principal amount of the aggregate term loans drawn for any prepayment prior to the first anniversary of the applicable funding date, (ii) 2% of
the original principal amount of the aggregate term loans drawn for any prepayment between the first and second anniversaries of the applicable
funding date or (iii) 1% of the original principal amount of the aggregate term loans drawn for any prepayment after the second anniversary of
the applicable funding date but before October 1, 2023. In October 2019, we repaid in full the $30.0 million that was outstanding under the Loan
Agreement and paid a prepayment fee of $0.6 million and a final payment fee of $1.7 million.

During  the  year  ended  December  31,  2019,  operating  activities  used  $96.4  million  of  cash  primarily  resulting  from  our  net  loss  of
$161.4 million, partially offset by non-cash adjustments of $67.6 million.  Net cash used by changes in our operating assets and liabilities during
the year ended December 31, 2019 consisted of a $5.1 million decrease in accounts payable and accrued expenses and a $0.8 million increase in
accounts  receivable,  which  were  partially  offset  by  a  $3.7  million  decrease  in  prepaid  expenses  and  other  assets.    The  decrease  in  accounts
payable and accrued expenses was primarily driven by lower levels of expenses, including sales discounts and allowances, as the result of the
disposition of RHOFADE, and lower research and development expenses as a result of the completion of our two pivotal Phase 3 clinical trials
for A-101 45% Topical Solution, as well as the timing of vendor invoicing and payments.  The decrease in prepaid expenses and other assets was
due  to  research  and  development  activities  primarily  related  to  preclinical  development  activities  for  ATI-450  and  ATI-502,  which  concluded
during the year ended December 31, 2019, and the elimination of sales and marketing activities as a result of the disposition of RHOFADE in
October  2019.    The  increase  in  accounts  receivable  was  primarily  the  result  of  the  timing  of  cash  receipts  from  our  contract  research
customers.    Non-cash  expenses  of  $67.6  million  were  composed  of  an  intangible  asset  impairment  charge  of  $27.6  million,  a  goodwill
impairment charge of $18.5 million, stock-based compensation expense of $16.2 million, a charge of $0.7 million related to the change in the fair
value of contingent consideration and depreciation and amortization expense of $6.4 million, partially offset by a gain of $1.9 million recognized
on the disposition of RHOFADE. 

During  the  year  ended  December  31,  2018,  operating  activities  used  $100.8  million  of  cash  primarily  resulting  from  our  net  loss  of
$132.7 million, partially offset by changes in our operating assets and liabilities of $9.4 million, and non-cash adjustments of $23.2 million.  Net
cash provided by changes in our operating assets and liabilities during the year ended December 31, 2018 consisted of a $13.8 million increase in
accounts payable and accrued expenses, which was partially offset by a $4.4 million increase in accounts receivable.  The increase in accounts
payable and accrued expenses was primarily driven by expenses incurred, but not yet paid, as of December 31, 2018, as well as the timing of
vendor invoicing and payments.  Expenses incurred, but not yet paid, as of December 31, 2018 primarily included sales and marketing expenses
related to the commercial launch of ESKATA in the United States in May 2018, amounts payable for copay assistance and commercial rebates
related to sales of RHOFADE which we began selling in December 2018, as well as expenses related to our Phase 3 clinical trials for A-101 45%
Topical Solution and our Phase 2 clinical trials for ATI-501 and ATI-502.  The increase in accounts receivable was the result of the commercial
launch  of  ESKATA  in  May  2018  and  sales  of  RHOFADE  which  we  acquired  in  November  2018.    Non-cash  expenses  of  $23.2  million  were
primarily composed of stock-based compensation expense.

During the year ended December 31, 2017, operating activities used $54.7 million of cash primarily resulting from our net loss of $68.5
million, partially offset by changes in our operating assets and liabilities of $0.9 million and non-cash adjustments of $13.0 million.  Net cash
used by changes in our operating assets and liabilities during the year ended December 31, 2017 consisted of a $4.3 million increase in prepaid
expenses  and  other  assets  offset  by  a  $5.2  million  increase  in  accounts  payable  and  accrued  expenses.   The  increase  in  prepaid  expenses  and
other assets was primarily due to a $2.0 million PDUFA fee paid to the FDA in conjunction with the filing of the NDA for ESKATA, as well as
deposits made for clinical supplies and development activities that were incurred during 2018.  The increase in accounts payable and accrued
expenses was primarily due to an increase of $1.2 million in accrued bonuses payable due to increased headcount, $0.6 million payable to NST
Consulting LLC in connection with the early termination of our sublease with them, as well as expenses incurred, but not yet paid, in connection
with  our  Phase  2  clinical  trials  for  A-101  45%  Topical  Solution,  ATI-501  and  ATI-502.    Non-cash  expenses  of  $13.0  million  included  stock-
based compensation expense of

$14.4 million, and $0.4 million of depreciation and amortization, partially offset by an adjustment to our deferred tax liability, net of $1.8 million
which was the result of the Tax Cuts and Jobs Act of 2017 enacted on December 22, 2017. 

Investing Activities

During the year ended December 31, 2019, investing activities provided $105.7 million of cash, consisting of proceeds from sales and
maturities  of  marketable  securities  of  $210.5  million  and  $34.2  million  from  the  disposition  of  RHOFADE,  partially  offset  by  purchases  of
marketable securities of $137.4 million and purchases of equipment of $1.6 million.

During  the  year  ended  December  31,  2018,  investing  activities  provided  $9.4  million  of  cash,  consisting  of  proceeds  from  sales  and
maturities of marketable securities of $239.4 million, partially offset by purchases of marketable securities of $161.6 million, $67.1 million for
the acquisition of RHOFADE, and purchases of equipment of $1.4 million. 

During  the  year  ended  December  31,  2017,  investing  activities  used  $55.7  million  of  cash,  consisting  of  purchases  of  marketable
securities of $197.3 million, $9.6 million for the acquisition of Confluence and purchases of property and equipment of $1.2 million, partially
offset by proceeds from sales and maturities of marketable securities of $152.5 million.

Financing Activities

During the year ended December 31, 2019, financing activities used $30.3 million of cash consisting of $30.0 million for the repayment
of  our  term  loan  with  Oxford  and  $0.5  million  related  to  finance  lease  payments,  partially  offset  by  $0.2  million  of  cash  received  from  the
exercise of employee stock options. 

During the year ended December 31, 2018, financing activities provided $128.3 million of cash and included net proceeds of $100.2
million received from our public offering of common stock in October 2018, $29.9 million of net borrowings pursuant to the Loan Agreement
with Oxford, and $0.6 million of cash received from the exercise of employee stock options, partially offset by $1.8 million paid to the former
Confluence equity holders as a result of the achievement of a development milestone and $0.6 million of finance lease payments.

During  the  year  ended  December  31,  2017,  financing  activities  provided  $100.4  million  of  cash  and  included  $19.3  million  of  net
proceeds received from the sale of common stock under our sales agreement with Cowen in April 2017, $80.9 million of net proceeds received
from  our  public  offering  of  common  stock  in  August  2017,  and  $0.2  million  of  cash  received  from  the  exercise  of  employee  stock  options,
partially offset by $0.1 million of finance lease payments for laboratory equipment. 

Funding Requirements

We anticipate we will incur net losses in the near term as we continue the clinical development of ATI-450 as a potential treatment for
rheumatoid arthritis and other immuno-inflammatory diseases, continue the development of our preclinical compounds, and continue to identify,
research  and  develop  additional  drug  candidates.    We  may  not  be  able  to  generate  revenue  from  these  programs  if,  among  other  things,  our
clinical trials are not successful, the FDA does not approve our drug candidates currently in clinical trials when we expect, or at all, or we are not
able to identify and consummate transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize
our drug candidates. 

Our primary uses of capital are, and we expect will continue in the near term to be, compensation and related expenses, clinical costs,
external  research  and  development  services,  laboratory  and  related  supplies,  legal  and  other  regulatory  expenses,  and  administrative  and
overhead costs.  Our future funding requirements will be heavily determined by the resources needed to support the development of our drug
candidates. 

As a publicly traded company, we have incurred and will continue to incur significant legal, accounting and other expenses that we were
not required to incur as a private company.  In addition, the Sarbanes-Oxley Act of 2002, as well as rules adopted by the SEC and the Nasdaq
Stock Market LLC, requires public companies to implement specified corporate governance practices that were not applicable to us prior to our
IPO.  We expect ongoing compliance with these rules and regulations will increase our legal and financial compliance costs and will make some
activities more time-

80

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

consuming and costly, in particular after we cease to be an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012,
or JOBS Act, which we expect to occur on December 31, 2020. 

We  believe  our  existing  cash,  cash  equivalents  and  marketable  securities  are  sufficient  to  fund  our  operating  and  capital  expenditure
requirements for a period greater than 12 months from the date of issuance of our consolidated financial statements that appear in Item 8 of this
Annual Report on Form 10-K based on our current operating assumptions.  We expect that we will require additional capital to complete the
clinical  development  of  ATI-450,  to  develop  our  preclinical  compounds,  and  to  support  our  discovery  efforts.   Additional  funds  may  not  be
available on a timely basis, on commercially acceptable terms, or at all, and such funds, if raised, may not be sufficient to enable us to continue
to implement our long-term business strategy. If we are unable to raise sufficient additional capital or generate revenue from transactions with
third-party  partners  for  the  development  and/or  commercialization  of  our  drug  candidates,  we  may  need  to  substantially  curtail  our  planned
operations. 

We may raise additional capital through the sale of equity or debt securities. In such an event, your ownership will be diluted, and the

terms of these securities may include liquidation or other preferences that adversely affect the rights of a holder of our common stock.

Because of the numerous risks and uncertainties associated with research and development of pharmaceutical drugs, we are unable to
estimate  the  exact  amount  of  our  working  capital  requirements.  Our  funding  requirements  in  the  near  term  will  depend  on  many  factors,
including:

·
·

·
·
·

·

·

the number and development requirements of the drug candidates that we may pursue;
the scope, progress, results and costs of preclinical development, laboratory testing and conducting preclinical and clinical trials for our
drug candidates;
the costs, timing and outcome of regulatory review of our drug candidates;
the extent to which we in-license or acquire additional drug candidates and technologies;
the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights
and defending any intellectual property-related claims;
our ability to identify and consummate transactions with third-party partners to further develop, obtain marketing approval for and/or
commercialize our drug candidates, and earn revenue from such arrangements; and
the revenue earned from our commercial products as a result of licenses to, or partnerships with, third parties.

See “Risk Factors” for additional risks associated with our substantial capital requirements.

Contractual Obligations and Commitments

We occupy space for our headquarters in Wayne, Pennsylvania under a sublease agreement which has a term through October 2023.  We

occupy office and laboratory space in St. Louis, Missouri under a sublease agreement which has a term through June 2029. 

We lease laboratory equipment used in our laboratory space in St. Louis, Missouri under two capital lease financing arrangements which

have terms through October 2020 and December 2020. 

Under the assignment agreement with the Estate of Mickey Miller pursuant to which we acquired intellectual property, we have agreed
to  pay  royalties  on  sales  of  ESKATA  and  related  products  at  rates  ranging  in  low  single-digit  percentages  of  net  sales,  as  defined  in  the
agreement.  Under the related finder’s services agreement with KPT Consulting, LLC, we have agreed to make a remaining payment of $3.0
million upon the achievement of a specified commercial milestone.  In addition, we have agreed to pay royalties on sales of ESKATA and related
products  at  a  low  single-digit  percentage  of  net  sales,  as  defined  in  the  agreement.    In  August  2019,  we  voluntarily  discontinued  the
commercialization of ESKATA in the United States and withdrew the marketing authorizations we had previously received for the product in all
countries outside of the United States.

Under  the  Rigel  License  Agreement,    we  have  agreed  to  make  remaining  aggregate  payments  of  up  to  $76.0  million  upon  the
achievement  of  specified  development  milestones,  such  as  clinical  trials  and  regulatory  approvals.  Further,  we  have  agreed  to  pay  up  to  an
additional  $10.5  million  to  Rigel  upon  the  achievement  of  a  second  set  of  development  milestones.  In  addition,  in  connection  with  the
amendment of the agreement in October 2019, we agreed to pay Rigel an amendment fee of $1.5 million in three installments of $500,000 in
January 2020, April 2020 and July 2020. With respect to any products we commercialize under the Rigel License Agreement, we will pay Rigel
quarterly tiered royalties on our annual net sales of each product developed using the licensed JAK inhibitors at a high single digit percentage of
annual net sales, subject to specified reductions. 

Under the Vixen Agreement, we are obligated to make aggregate payments of up to $18.0 million upon the achievement of specified
pre-commercialization milestones for three products covered by the Vixen patent rights in the United States, the European Union and Japan, and
aggregate payments of up to $22.5 million upon the achievement of specified commercial milestones for products covered by the Vixen patent
rights.    We  are  also  obligated  to  make  an  annual  payment  of  $0.1  million  through  March  2022,  which  amounts  are  creditable  against  any
specified  future  payments  that  may  be  paid  under  the  Vixen  Agreement.    With respect to any covered  products  that  we  commercialize  under
the Vixen Agreement, we are obligated to pay low single-digit percentage of annual net sales, subject to specified reductions, limitations and
other adjustments, until the date that all of the patent rights for that product have expired, as determined on a country-by-country and product-by-
product basis or, in specified circumstances, ten years from the first commercial sale of such product.  If we sublicense any of the patent rights
and  know-how  acquired  pursuant  to  the  Vixen Agreement,  we  will  be  obligated  to  pay  a  portion  of  any  consideration  we  receive  from  such
sublicenses in specified circumstances. 

Under the Columbia License Agreement, we are obligated to pay an annual license fee of $10,000, subject to specified adjustments for
patent expenses incurred by Columbia and creditable against any royalties that may be paid under the license agreement.  We are also obligated
to pay up to an aggregate of $11.6 million upon the achievement of specified commercial milestones, including specified levels of net sales of
products  covered  by  Columbia  patent  rights  and/or  know-how,  and  royalties  at  a  sub-single-digit  percentage  of  annual  net  sales  of  products
covered  by  Columbia  patent  rights  and/or  know-how,  subject  to  specified  adjustments.    If  we  sublicense  any  of  Columbia’s  patent  rights  and
know-how acquired pursuant to the Columbia License Agreement, we will be obligated to pay Columbia a portion of any consideration Vixen
receives from such sublicenses in specified circumstances. 

Under  the  Confluence  Agreement,    we  are  obligated  to  make  remaining  aggregate  payments  of  up  to  $75.0  million  upon  the
achievement  of  specified  regulatory  and  commercialization  milestones.    With  respect  to  any  covered  products  we  commercialize,  we  are
obligated to pay a low single-digit percentage of annual net sales, subject to specified reductions, limitations and other adjustments, until the date
that all of the patent rights for that product have expired, as determined on a country-by-country and product-by-product basis or, in specified
circumstances,  ten  years  from  the  first  commercial  sale  of  such  product.    If  we  sublicense  any  of  the  patent  rights  and  know-how  acquired
pursuant to the Confluence Agreement, we will be obligated to pay a portion of any consideration we receive from such sublicenses in specified
circumstances. 

We  enter  into  contracts  in  the  normal  course  of  business  with  CROs  for  clinical  trials,  preclinical  research  studies  and  testing,
manufacturing  and  other  services  and  products  for  operating  purposes.  These  contracts  generally  provide  for  termination  upon  notice,  and
therefore we believe that our non-cancelable obligations under these agreements are not material. 

Off-Balance Sheet Arrangements

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

and regulations of the SEC.

Recently Issued Accounting Pronouncements

In  November  2018,  the  Financial  Accounting  Standards  Board,  or  FASB,  issued  Accounting  Standards  Update,  or  ASU,  2018-18,
Collaborative  Arrangements  (Topic  808):    Clarifying  the  Interaction  Between  Topic  808  and  Topic  606,  which,  among  other  things,  provides
guidance on how to assess whether certain collaborative arrangement transactions should be accounted for under Topic 606.  The amendments in
this  ASU  are  effective  for  fiscal  years,  and  interim  periods  within  those  fiscal  years,  beginning  after  December  15,  2019.    We  adopted  this
standard as of January 1, 2020, the impact of which on our consolidated financial statements was not significant. 

In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40).  ASU
2018-15  requires  a  customer  in  a  cloud  computing  arrangement  that  is  a  service  contract  to  follow  the  internal-use  software  guidance  in
Accounting Standards Codification, or ASC, 350-40 to determine which implementation costs to capitalize as assets or expense as incurred.  The
standard will be effective for fiscal years beginning after December 15, 2019, including interim periods within such fiscal years.  We adopted this
standard as of January 1, 2020, the impact of which on our consolidated financial statements was not significant.   

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820).  The FASB developed the amendments to ASC
820  as  part  of  its  broader  disclosure  framework  project,  which  aims  to  improve  the  effectiveness  of  disclosures  in  the  notes  to  financial
statements  by  focusing  on  requirements  that  clearly  communicate  the  most  important  information  to  users  of  the  financial  statements.    This
update  eliminates  certain  disclosure  requirements  for  fair  value  measurements  for  all  entities,  requires  public  entities  to  disclose  certain  new
information and modifies some of the existing disclosure requirements.  The standard will be effective for fiscal years beginning after December
15,  2019,  including  interim  periods  within  such  fiscal  years.    We  adopted  this  standard  as  of  January  1,  2020,  the  impact  of  which  on  our
consolidated financial statements was not significant. 

In June 2018, the FASB, issued ASU 2018-07, Compensation—Stock Compensation (Topic 718).  The amendments in this ASU expand
the scope of Topic 718 to include stock-based compensation arrangements with non-employees except for specific guidance on option pricing
model inputs and cost attribution.  ASU 2018-07 is effective for annual reporting periods beginning after December 31, 2018, including interim
periods within that year.  We adopted this standard as of January 1, 2019, the impact of which on our consolidated financial statements was not
significant.   

In  February  2016,  the  FASB  issued  ASU  2016-02,  Leases  (Topic  842).    In  July  2018,  the  FASB  issued  ASU  2018-10,  Codification
Improvements to Topic 842, Leases, and ASU 2018-11, Targeted Improvements, both of which included a number of technical corrections and
improvements, including additional options for transition.  The new standard establishes a right-of-use model that requires a lessee to record a
right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months.  Leases are classified as either finance
or  operating,  with  classification  affecting  the  pattern  of  expense  recognition  in  the  income  statement.   ASU  2016-02  is  effective  for  annual
periods beginning after December 15, 2018, including interim periods within those annual periods.  The amendments in ASU 2016-02 must be
applied to all leases existing at the date a company initially applies the standard. 

We adopted the new standard as of January 1, 2019, using the effective date as the date of initial application, and we used the modified
retrospective approach.  In addition, we elected the practical expedients permitted under the transition guidance within the new standard, which,
among other things, allowed us to carry forward the historical lease identification and classification.  We also elected the practical expedient to
not separate lease and non-lease components, as well as the short-term lease exemption which allowed us to not capitalize leases with terms less
than  12  months  that  do  not  contain  a  reasonably  certain  purchase  option.    Our  consolidated  financial  statements  have  not  been  updated,  and
disclosures required by the new standard have not been provided, for periods before January 1, 2019. 

The adoption of ASU 2016-02 resulted in us recording additional assets and liabilities of $2.1 million and $2.3 million, respectively,
upon adoption on January 1, 2019.  The adoption of ASU 2016-02 did not have a material impact on our consolidated statement of operations or
cash flows.

Emerging Growth Company Status

The  Jumpstart  Our  Business  Startups  Act  of  2012,  or  the  JOBS  Act,  permits  an  “emerging  growth  company”  such  as  us  to  take
advantage  of  an  extended  transition  period  to  comply  with  new  or  revised  accounting  standards  applicable  to  public  companies  until  those
standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision and, as a result, we will comply
with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies. 

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Our  cash  equivalents  and  marketable  securities  consist  of  money  market  funds,  asset-backed  securities,  commercial  paper,  corporate
debt securities and government agency debt. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the
general  level  of  U.S.  interest  rates.    Our  marketable  securities  are  subject  to  interest  rate  risk  and  will  fall  in  value  if  market  interest  rates
increase.    However,  due  to  the  short-term  nature  and  low-risk  profile  of  our  investment  portfolio,  we  do  not  expect  that  an  immediate  10%
change in market interest rates would have a material effect on the fair market value of our investment portfolio.  We have the ability to hold our
marketable  securities  until  maturity,  and  therefore  we  would  not  expect  our  operating  results  or  cash  flows  to  be  affected  to  any  significant
degree by the effect of a change in market interest rates on our investments.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Aclaris Therapeutics, Inc. and its subsidiaries (the “Company”) as of
December 31, 2019 and 2018, and the related consolidated statements of operations and comprehensive loss, of stockholders’ equity and of cash
flows for each of the three years in the period ended December 31, 2019, including the related notes (collectively referred to as the “consolidated
financial statements”).  In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the
Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2019 in conformity with accounting principles generally accepted in the United States of America. 

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an
opinion  on  the  Company’s  consolidated  financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public
Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance
with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.    

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated 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 consolidated 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  consolidated  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 consolidated financial statements. We
believe that our audits provide a reasonable basis for our opinion.    

/s/ PricewaterhouseCoopers LLP
Philadelphia, Pennsylvania

We have served as the Company’s auditor since 2015.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands, except share and per share data)

1. Organization and Nature of Business

Overview

Aclaris  Therapeutics,  Inc.  was  incorporated  under  the  laws  of  the  State  of  Delaware  in  2012.    In  July  2015,  Aclaris  Therapeutics
International Limited (“ATIL”) was established under the laws of the United Kingdom as a wholly-owned subsidiary of Aclaris Therapeutics,
Inc.  In March 2016, Vixen Pharmaceuticals, Inc. (“Vixen”) became a wholly-owned subsidiary of Aclaris Therapeutics, Inc., and in September
2018,  Vixen  was  dissolved.    In  August  2017,  Confluence  Life  Sciences,  Inc.,  now  known  as  Aclaris  Life  Sciences,  Inc.  (“Confluence”)  was
acquired by Aclaris Therapeutics, Inc. and became a wholly-owned subsidiary thereof.  Aclaris Therapeutics, Inc., ATIL, Vixen and Confluence
are referred to collectively as the “Company”.  The Company is a physician-led biopharmaceutical company focused on immuno-inflammatory
diseases.  The Company currently has a pipeline of drug candidates focused on immuno-inflammatory diseases, as well as one product approved
by  the  U.S.  Food  and  Drug  Administration  (“FDA”)  that  it  is  not  currently  distributing,  marketing  or  selling,  and  other  investigational  drug
candidates. In September 2019, the Company announced the completion of a strategic review of its business, as a result of which it is refocusing
its resources on its immuno-inflammatory development programs. The Company plans to pursue strategic alternatives, including identifying and
consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize its drug candidates
and ESKATA (hydrogen peroxide) topical solution, 40% (w/w) (“ESKATA”), the Company’s non-marketed FDA-approved product.    

Liquidity

The Company’s consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and
the satisfaction of liabilities in the ordinary course of business.  At December 31, 2019, the Company had cash, cash equivalents and marketable
securities of $75,015 and an accumulated deficit of $453,527.  Since inception, the Company has incurred net losses and negative cash flows
from  its  operations.    Prior  to  the  acquisition  of  Confluence  in  August  2017,  the  Company  had  never  generated  revenue.    There  can  be  no
assurance that profitable operations will ever be achieved, and, if achieved, will be sustained on a continuing basis.  In addition, development
activities, including clinical and preclinical testing of the Company’s drug candidates, will require significant additional financing.  The future
viability of the Company is dependent on its ability to successfully develop its drug candidates and to generate revenue from identifying and
consummating  transactions  with  third-party  partners  to  further  develop,  obtain  marketing  approval  for  and/or  commercialize  its  development
assets or to raise additional capital to finance its operations.   The Company expects that it will require additional capital to complete the clinical
development of ATI-450, to develop its preclinical compounds, and to support its discovery efforts.  Additional funds may not be available on a
timely basis, on commercially acceptable terms, or at all, and such funds, if raised, may not be sufficient to enable the Company to continue to
implement its long-term business strategy.  If the Company is unable to raise sufficient additional capital or generate revenue from transactions
with  third-party  partners  for  the  development  and/or  commercialization  of  its  drug  candidates,  it  may  need  to  substantially  curtail  planned
operations.  The  Company’s  failure  to  raise  capital  as  and  when  needed  could  have  a  negative  impact  on  its  financial  condition  and  ability  to
pursue its business strategies.  

In accordance with Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue
as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and events, considered in the aggregate, that
raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that its consolidated financial
statements are issued.  As of the report date, the Company believes the actions described below are probable of being implemented effectively
and of alleviating the conditions or events that exist which raise substantial doubt about its ability to continue as a going concern within one year
after  the  date  of  the  issuance  of  these  consolidated  financial  statements.      The  Company  believes  its  existing  cash,  cash  equivalents  and
marketable securities are sufficient to fund its operating and capital expenditure requirements for a period greater than 12 months from the date
of issuance of these consolidated financial statements.

Table of Contents

The Company has taken a number of actions to support its operations and meet its liquidity needs.  In September 2019, the Company
announced the completion of a strategic review and its decision to refocus its resources on its immuno-inflammatory development programs and
to  pursue  strategic  alternatives,  including  identifying  and  consummating  transactions  with  third-party  partners,  to  further  develop,  obtain
marketing  approval  for  and/or  commercialize  its  drug  candidates  and  ESKATA.     As  a  result  of  this  decision,  the  Company  restructured  its
operations  and  terminated  employees,  some  of  which  are  occurring  through  termination  dates  into  2020,  which  will  result  in  lower  operating
costs in the future. In October 2019, the Company sold the worldwide rights to RHOFADE to further its focus on its development programs and
improve cash flow. 

The  Company’s  plans  to  further  alleviate  the  substantial  doubt  about  its  going  concern,  which  are  probable  of  effectively  being
implemented and mitigating these conditions, primarily include its ability to control the timing and spending on its research and development
programs.   The  Company  may  also  consider  other  plans  to  fund  its  operations  including:  (1)  raising  additional  capital  through  debt  or  equity
financings; (2) identification of third-party partners to further develop, obtain marketing approval for and/or commercialize its drug candidates
and  ESKATA,  which  may  generate  revenue  and/or  milestone  payments;  (3)  reducing  spending  on  one  or  more  research  and  development
programs  by  delaying  or  discontinuing  development;  and/or  (4)  further  restructuring  its  operations  to  change  its  overhead  structure.  Finally,
additional  funds  may  not  be  available  on  a  timely  basis,  on  commercially  acceptable  terms,  or  at  all,  and  such  funds,  if  raised,  may  not  be
sufficient to enable the Company to continue to implement its long-term business strategy. 

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in
the  United  States  (“GAAP”).    The  consolidated  financial  statements  of  the  Company  include  the  accounts  of  the  operating  parent  company,
Aclaris Therapeutics, Inc., and its wholly-owned subsidiaries, Confluence, ATIL and Vixen.  All significant intercompany transactions have been
eliminated.    Based  upon  the  revenue  from  contract  research  services,  the  Company  believes  that  gross  profit  does  not  provide  a  meaningful
measure of profitability and, therefore, has not included a line item for gross profit on the consolidated statement of operations. 

Discontinued Operations

In  September  2019,  the  Company  announced  the  completion  of  a  strategic  review  and  its  decision  to  refocus  its  resources  on  its
immuno-inflammatory development programs and to actively seek partners for its commercial products.  The Company also announced a plan to
terminate 86 employees (see Note 17). 

The accompanying consolidated financial statements have been recast for all periods presented to reflect the assets, liabilities, revenue
and expenses related to the Company’s commercial products as discontinued operations (see Note 18).  The accompanying consolidated financial
statements  are  generally  presented  in  conformity  with  the  Company’s  historical  format,  even  in  certain  situations  where  reclassifications  to
discontinued  operations  have  resulted  in  $0  values  being  presented.    The  Company  believes  this  format  provides  comparability  with  its
previously filed financial statements. 

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 expenses during the reporting periods.  Significant estimates and assumptions reflected in these financial statements include,
but  are  not  limited  to,  research  and  development  expenses,  contingent  consideration  and  the  valuation  of  stock-based  awards.    Estimates  are
periodically reviewed in light of changes in circumstances, facts and experience.  Actual results could differ from the Company’s estimates.

Revenue Recognition

The  Company  accounts  for  revenue  in  accordance  with  Accounting  Standards  Codification  (“ASC”)  Topic  606,  Revenue  from

Contracts with Customers.  Under ASC Topic 606, revenue is recognized when a customer obtains control

92

 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

of promised goods or services in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those
goods or services. 

To determine revenue recognition in accordance with ASC Topic 606, the Company 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) performance obligations are satisfied.  At
contract  inception,  the  Company  assesses  the  goods  or  services  promised  within  a  contract  with  a  customer  to  identify  the  performance
obligations, and to determine if they are distinct.  The Company recognizes the revenue that is allocated to each distinct performance obligation
when (or as) that performance obligation is satisfied.  The Company only recognizes revenue when collection of the consideration it is entitled to
under a contract with a customer is probable. 

Product Sales, net

The Company sold RHOFADE (oxymetazoline hydrochloride) cream, 1% (“RHOFADE”) and ESKATA (hydrogen peroxide) Topical
Solution, 40% (w/w) (“ESKATA”) during the years ended December 31, 2019 and 2018 to a limited number of wholesalers in the United States
(collectively,  its  “Customers”).    These  Customers  subsequently  resold  the  Company’s  products  to  pharmacies  and  health  care  providers.    In
addition to distribution agreements with Customers, the Company entered into, or was subject to, arrangements with third-party payors, including
pharmacy  benefit  managers  and  government  agencies,  as  well  as  group  purchasing  organizations  (“GPOs”),  which  provided  for  government
mandated or privately negotiated rebates, chargebacks, and discounts with respect to the purchase of the Company’s commercial products.  The
Company  discontinued  selling  ESKATA  in  August  2019.   The  Company  sold  the  worldwide  rights  to  RHOFADE  in  October  2019  (see  Note
3).  Product sales, net has been reclassified to discontinued operations for all periods presented. 

  The  Company  also 

included  estimates  of  variable  consideration 

The  Company  recognized  revenue  from  product  sales  at  the  point  the  Customer  obtained  control  of  the  product,  which  generally
occurred  upon  delivery. 
the  same  period  revenue  was
recognized.  Components of variable consideration include trade discounts and allowances, product returns, government rebates, discounts and
rebates,  other  incentives  such  as  patient  co-pay  assistance,  and  other  fee  for  service  amounts.    Variable  consideration  was  recorded  on  the
consolidated balance sheet as either a reduction of accounts receivable, if payable to a Customer, or as a current liability, if payable to a third
party other than a Customer.  The Company considered all relevant information when estimating variable consideration such as contractual and
statutory  requirements,  specific  known  market  events  and  trends,  industry  data  and  forecasted  customer  buying  and  payment  patterns.    The
amount  of  net  revenue  that  can  be  recognized  is  constrained  by  estimates  of  variable  consideration  which  are  included  in  the  transaction
price.  Payment terms with Customers did not exceed one year and, therefore, the Company did not account for a financing component in its
arrangements.  The Company expensed incremental costs of obtaining a contract with a Customer, including sales commissions, when incurred
as the period of benefit was less than one year. 

in 

Trade  Discounts  and  Allowances  -  The  Company  provided  Customers  with  trade  discounts,  rebates,  allowances  and/or  other

incentives.  The Company recorded estimates for these items as a reduction of revenue in the same period the revenue was recognized. 

Government  and  Payor  Rebates  -  The  Company  contracted  with,  or  was  subject  to  arrangements  with,  certain  third-party  payors,
including  pharmacy  benefit  managers  and  government  agencies,  for  the  payment  of  rebates  with  respect  to  utilization  of  its  commercial
products.  The Company also entered into agreements with GPOs that provided for administrative fees and discounted pricing in the form of
volume-based rebates.  The Company was also subject to discount and rebate obligations under state Medicaid programs and Medicare.  The
Company recorded estimates for these discounts and rebates as a reduction of revenue in the same period the revenue was recognized. 

Other  Incentives  -  The  Company  maintained  a  co-pay  assistance  program  which  was  intended  to  provide  financial  assistance  to
qualified  commercially-insured  patients  with  prescription  drug  co-payments  required  by  third-party  payors.    The  Company  estimated  and
recorded accruals for these incentives as a reduction of revenue in the period the revenue was recognized.   The Company estimated amounts for
co-pay assistance based upon the number of claims and the cost per claim that the Company expected to receive associated with product that had
been sold to Customers but remained in the distribution channel at the end of each reporting period. 

93

 
 
 
 
 
 
 
 
Table of Contents

Product Returns - Consistent with industry practice, the Company has a product returns policy for RHOFADE that provides Customers
a  right  of  return  for  product  purchased  within  a  specified  period  prior  to  and  subsequent  to  the  product’s  expiration  date.  The  right  of  return
lapses upon shipment of the product to a patient.  The Company recorded an estimate for the amount of its products which may be returned as a
reduction of revenue in the period the related revenue was recognized. The Company’s estimate for product returns was based upon available
industry data and its own sales information, including its visibility into the inventory remaining in the distribution channel.  There is no return
liability associated with sales of ESKATA as the Company had a no returns policy for ESKATA when it was commercialized.

Contract Research

The  Company  earns  contract  research  revenue  from  the  provision  of  laboratory  services  to  clients  through  Confluence,  its  wholly-
owned subsidiary.  Contract research revenue is generally evidenced by contracts with clients which are on an agreed upon fixed-price, fee-for-
service  basis  and  are  generally  billed  on  a  monthly  basis  in  arrears  for  services  rendered.    Revenue  related  to  these  contracts  is  generally
recognized as the laboratory services are performed, based upon the rates specified in the contracts.  Under ASC Topic 606, the Company elected
to  apply  the  “right  to  invoice”  practical  expedient  when  recognizing  contract  research  revenue.    The  Company  recognizes  contract  research
revenue in the amount to which it has the right to invoice. 

The Company has also received revenue from grants under the Small Business Innovation Research program of the National Institutes
of Health (“NIH”).  During the year ended December 31, 2018, the Company had two active grants from NIH which were related to early-stage
research.   As  of  December  31,  2019,  there  were  no  remaining  funds  available  to  the  Company  under  the  grants.    The  Company  recognizes
revenue related to grants as amounts become reimbursable under each grant, which is generally when research is performed, and the related costs
are incurred. 

Other Revenue

Licenses of Intellectual Property – The Company recognizes revenue received from non-refundable, upfront fees related to the licensing
of  intellectual  property  when  the  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the
arrangement, the license has been transferred to the customer, and the customer is able to use and benefit from the license.

Milestone  Payments  –    At  the  inception  of  each  arrangement  that  includes  milestone  payments,  the  Company  evaluates  whether  the
milestones  are  considered  probable  of  being  reached  and  estimates  the  amount  to  be  included  in  the  transaction  price  using  the  most  likely
amount method.  If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the amount
allocated to the license of intellectual property.  Milestone payments that are not within the control of the Company or the customer, such as
regulatory approvals, are not considered probable of being achieved until those approvals are received.

Cash, Cash Equivalents and Restricted Cash

The Company considers all short-term, highly liquid investments with original maturities of 90 days or less at acquisition date to be
cash  equivalents.    Cash  equivalents,  which  have  consisted  of  money  market  accounts,  commercial  paper  and  corporate  debt  securities  with
original maturities of less than three months, are stated at fair value.  Restricted cash as of December 31, 2019 included $1,750 placed in escrow
pursuant to the asset purchase agreement with EPI Health, LLC (“EPI Health”) (see Note 3). 

Marketable Securities

Marketable  securities  with  original  maturities  of  greater  than  three  months  and  remaining  maturities  of  less  than  one  year  from  the
balance sheet date are classified as short-term. Marketable securities with remaining maturities of greater than one year from the balance sheet
date are classified as long-term. 

94

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

The  Company  classifies  all  of  its  marketable  securities  as  available-for-sale  securities.  The  Company’s  marketable  securities  are
measured and reported at fair value using quoted prices in markets that are not active for identical or similar securities. Unrealized gains and
losses are reported as a separate component of stockholders’ equity. The cost of securities sold is determined on a specific identification basis,
and realized gains and losses, if any, are included in other income, net within the consolidated statement of operations and comprehensive loss. If
any adjustment to fair value reflects a decline in the value of the investment, the Company considers available evidence to evaluate the extent to
which  the  decline  is  “other  than  temporary”  and  reduces  the  investment  to  fair  value  through  a  charge  to  the  statement  of  operations  and
comprehensive loss. 

Inventory

Inventory  includes  the  third-party  cost  of  manufacturing  and  assembly  of  finished  product,  quality  control  and  other  overhead
costs.  Inventory is stated at the lower of cost or net realizable value.  Inventory is adjusted for short-dated, unmarketable inventory equal to the
difference  between  the  cost  of  inventory  and  the  estimated  value  based  upon  assumptions  about  future  demand  and  market  conditions.    The
Company had $0 and $791 of inventory as of December 31, 2019 and 2018, respectively, which was comprised primarily of finished goods and
has been reclassified to discontinued operations for all periods presented. 

Property and Equipment

Property  and  equipment  are  stated  at  cost  less  accumulated  depreciation.  Depreciation  expense  is  recognized  using  the  straight-line
method  over  the  useful  life  of  the  asset.  Computer  equipment  is  depreciated  over  three  years.  Manufacturing  and  laboratory  equipment  is
depreciated over five years. Furniture and fixtures are depreciated over five years.  Leasehold improvements are depreciated over the shorter of
the lease term or their useful life.  Expenditures for repairs and maintenance of assets are charged to expense as incurred. Upon retirement or
sale, the cost and related accumulated depreciation of assets disposed of are removed from the accounts and any resulting gain or loss is included
in loss from operations. 

Impairment of Long-Lived Assets

Long-lived assets consist of property and equipment. Long-lived assets to be held and used are tested for recoverability whenever events
or  changes  in  business  circumstances  indicate  that  the  carrying  amount  of  the  assets  may  not  be  fully  recoverable.  Factors  that  the  Company
considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations,
significant negative industry or economic trends and significant changes or planned changes in the use of the assets. If an impairment review is
performed to evaluate a long-lived asset for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from
the  use  and  eventual  disposition  of  the  long-lived  asset  to  its  carrying  value.  An  impairment  loss  would  be  recognized  when  estimated
undiscounted future cash flows expected to result from the use of an asset are less than its carrying amount. The impairment loss would be based
on the excess of the carrying value of the impaired asset over its fair value, determined based on discounted cash flows.

Intangible Assets

Intangible  assets  include  both  definite-lived  and  indefinite-lived  assets.    Definite-lived  intangible  assets  are  amortized  over  their
estimated useful life based on the pattern over which the intangible assets are consumed or otherwise used up.  If that pattern cannot be reliably
determined,  the  straight-line  method  of  amortization  is  used.    Definite-lived  intangible  assets  consist  of  a  research  technology  platform  the
Company  acquired  through  the  acquisition  of  Confluence.    Prior  to  the  disposition  in  2019,  definite-lived  intangible  assets  also  included  the
intellectual  property  rights  related  to  RHOFADE.    Indefinite-lived  intangible  assets  consist  of  an  in-process  research  and  development
(“IPR&D”) drug candidate acquired through the acquisition of Confluence.  IPR&D assets are considered indefinite-lived until the completion or
abandonment of the associated research and development efforts.  The cost of IPR&D is either amortized over its estimated useful life beginning
when the underlying drug candidate is approved and launched commercially, or expensed immediately if development of the drug candidate is
abandoned.

Definite-lived intangible assets are tested for impairment when events or changes in circumstances indicate that the carrying value of
the asset may not be recoverable.  Indefinite-lived intangible assets are tested for impairment at least annually, which the Company performs
during the fourth quarter, or when indicators of an impairment are present.  The Company recognizes impairment losses when and to the extent
that the estimated fair value of an intangible asset is less than its carrying value. 

During the year ended December 31, 2019, the Company performed an impairment analysis of the RHOFADE intangible asset due to its
decision  to  discontinue  commercial  operations  and  actively  seek  a  commercialization  partner  for  RHOFADE.    The  Company’s  impairment
analysis, which primarily utilized a market-participant’s indication of fair value, resulted in a fair value for the RHOFADE intangible asset which
was  less  than  its  carrying  value.    As  a  result,  the  Company  recorded  an  impairment  charge  of  $27,638,  which  is  included  in  discontinued
operations on the consolidated statement of operations, to adjust the carrying value of the RHOFADE intangible asset to its net realizable value
(see Note 3). 

Goodwill

Goodwill is not amortized, but rather is subject to testing for impairment at least annually, which the Company performs either during
the fourth quarter or when indicators of an impairment are present.  The Company considers each of its operating segments, therapeutics and
contract  research,  to  be  a  reporting  unit  since  this  is  the  lowest  level  for  which  discrete  financial  information  is  available.    The  Company
attributed  the  full  amount  of  the  goodwill  acquired  with  Confluence,  or  $18,504,  to  the  therapeutics  segment.    The  annual  impairment  test
performed  by  the  Company  is  a  qualitative  assessment  based  upon  current  facts  and  circumstances  related  to  operations  of  the  therapeutics
segment.  If the qualitative assessment indicates an impairment may be present, the Company would perform the required quantitative analysis
and  an  impairment  charge  would  be  recognized  to  the  extent  that  the  estimated  fair  value  of  the  reporting  unit  is  less  than  its  carrying
amount.  However, any loss recognized would not exceed the total amount of goodwill allocated to that reporting unit. 

During the year ended December 31, 2019, the Company performed an impairment analysis due to the decline in its stock price, which
was considered a triggering event to evaluate goodwill for impairment.  The Company’s impairment analysis, using a market approach, noted
that its stock price, including a reasonable control premium, resulted in a fair value for the therapeutics reporting unit which was less than its
carrying value.  As a result, the Company recorded an impairment charge of $18,504, the full balance of goodwill. 

Leases

Leases represent a company’s right to use an underlying asset and a corresponding obligation to make payments to a lessor for the right
to use those assets.  The Company evaluates leases at their inception to determine if they are an operating lease or a finance lease.  A lease is
accounted for as a finance lease if it meets one of the following five criteria: the lease has a purchase option that is reasonably certain of being
exercised, the present value of the future cash flows are substantially all of the fair market value of the underlying asset, the lease term is for a
significant portion of the remaining economic life of the underlying asset, the title to the underlying asset transfers at the end of the lease term, or
if the underlying asset is of such a specialized nature that it is expected to have no alternative uses to the lessor at the end of the term.  Leases
that do not meet the finance lease criteria are accounted for as an operating lease. 

The Company recognizes assets and liabilities for leases at their inception based upon the present value of all payments due under the
lease.    The  Company  uses  an  implicit  interest  rate  to  determine  the  present  value  of  finance  leases,  and  its  incremental  borrowing  rate  to
determine the present value of operating leases.  The Company determines incremental borrowing rates by referencing collateralized borrowing
rates for debt instruments with terms similar to the respective lease.  The Company recognizes expense for operating and finance leases on a
straight-line  basis  over  the  term  of  each  lease,  and  interest  expense  related  to  finance  leases  is  recognized  over  the  lease  term  based  on  the
effective  interest  method.    The  Company  includes  estimates  for  any  residual  value  guarantee  obligations  under  its  leases  in  lease  liabilities
recorded on its consolidated balance sheet. 

Right-of-use  assets  are  included  in  other  assets  and  property  and  equipment,  net  on  the  Company’s  consolidated  balance  sheet  for
operating and finance leases, respectively.  Obligations for lease payments are included in current portion of lease liabilities and other liabilities
on the Company’s consolidated balance sheet for both operating and finance leases.

Contingent Consideration

The Company initially recorded the contingent consideration related to future potential payments based upon the achievement of certain
development,  regulatory  and  commercial  milestones,  resulting  from  the  acquisition  of  Confluence,  at  its  estimated  fair  value  on  the  date  of
acquisition.  Changes in fair value reflect new information about the likelihood of the payment of the contingent consideration and the passage of
time.  For example, if the timing of the development of an acquired drug candidate, or the size of potential commercial opportunities related to an
acquired drug, differ from the Company’s assumptions, then the fair value of contingent consideration would be adjusted accordingly.  Future
changes in the fair value of the contingent consideration, if any, will be recorded as income or expense in the Company’s consolidated statement
of operations. 

Research and Development Costs

Research  and  development  costs  are  expensed  as  incurred.  Research  and  development  expenses  include  salaries,  stock-based
compensation and benefits of employees, fees paid under licensing agreements, fees paid under a third party assignment agreement and other
operational  costs  related  to  the  Company’s  research  and  development  activities,  including  depreciation  expenses  and  the  cost  of  research  and
development  contracts  which  the  Company  has  entered  into  with  outside  vendors  to  conduct  both  preclinical  studies  and  clinical
trials.  Significant judgment and estimates are made in determining the amount of research and development costs recognized in each reporting
period.  The Company analyzes the progress of its preclinical studies and clinical trials, completion of milestone events, invoices received and
contracted  costs  when  estimating  research  and  development  costs.  Actual  results  could  differ  from  the  Company’s  estimates.  The  Company’s
historical estimates for research and development costs have not been materially different from the actual costs.

Stock-Based Compensation

The Company measures the compensation expense of stock-based awards granted to employees and directors using the grant date fair
value of the award.  The Company has issued stock options and restricted stock unit (“RSU”) awards with service-based vesting conditions, as
well  as  with  performance-based  vesting  conditions.    The  Company  has  not  issued  awards  that  include  market-based  conditions.    For  service-
based  awards  the  Company  recognizes  stock-based  compensation  expense  on  a  straight-line  basis  over  the  requisite  service  period.    For
performance-based awards the Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period
beginning  in  the  period  that  it  becomes  probable  the  performance  conditions  will  occur.   At  each  balance  sheet  date,  the  Company  evaluates
whether any performance conditions related to a performance-based award have changed.  The effect of any change in performance conditions
would  be  recognized  as  a  cumulative  catch-up  adjustment  in  the  period  such  change  occurs,  and  any  remaining  unrecognized  compensation
expense would be recognized on a straight-line basis over the remaining requisite service period.  The impact of forfeitures is recognized in the
period in which they occur. 

The Company initially measures the compensation expense of stock-based awards granted to consultants using the grant date fair value
of the award. Compensation expense is recognized over the period during which services are rendered by such consultants. At the end of each
financial reporting period prior to completion of services being rendered, the compensation expense related to these awards is remeasured using
the then current fair value of the Company’s common stock for RSUs, or based upon updated assumptions in the Black-Scholes option pricing
model for stock option awards. 

The Company classifies stock-based compensation expense in its statement of operations and comprehensive loss in the same manner in

which the award recipient’s payroll costs are classified or in which the award recipients’ service payments are classified. 

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company
estimates  its  expected  stock  volatility  based  on  the  historical  volatility  of  a  set  of  peer  companies,  which  are  publicly  traded,  and  expects  to
continue to do so until it has adequate historical data regarding the volatility of its own publicly-traded stock price. The expected term of the
Company’s stock options has been determined using the “simplified” method for awards that qualify as “plain vanilla” options. The expected
term of stock options granted to non-employees is equal to the contractual term of the option award. The risk-free interest rate is determined by
reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of
the award. The Company uses an expected dividend yield of zero based on the fact that the Company has never paid cash dividends and does not
expect to pay cash dividends in the future.  Prior to the Company’s initial public offering

97

 
 
 
 
 
 
 
 
Table of Contents

in October 2015 (“IPO”), the Company valued its common stock using a hybrid method to estimate its enterprise value.  The hybrid method used
was  a  probability-weighted  expected  return  method  which  was  a  scenario-based  methodology  that  estimated  the  fair  value  of  the  Company’s
common stock based upon an analysis of future values for the Company assuming various outcomes.  The hybrid method used calculated equity
values using an option pricing model in one or more of scenarios, and also considered the rights of each class of stock. 

The fair value of each RSU is measured using the closing price of the Company’s common stock on the date of grant.

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 recovery of the expenditure.  Amounts incurred are classified as general and administrative expenses.

Foreign Currency Translation

The reporting currency of the Company is the U.S. Dollar. The functional currency of ATIL, the Company’s wholly-owned subsidiary,
is the British Pound.  Assets and liabilities of ATIL are translated into U.S. Dollars based on exchange rates at the end of each reporting period.
Revenues and expenses are translated at average exchange rates during the reporting period.  Gains and losses arising from the translation of
assets  and  liabilities  are  included  as  a  component  of  accumulated  other  comprehensive  loss  within  the  Company’s  consolidated  balance
sheet.    Gains  and  losses  resulting  from  foreign  currency  transactions  are  reflected  within  the  Company’s  consolidated  statement  of
operations.  The Company has not utilized foreign currency hedging strategies to mitigate the effect of its foreign currency exposure.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and
liabilities  for  the  expected  future  tax  consequences  of  events  that  have  been  recognized  in  the  financial  statements  or  in  the  Company’s  tax
returns. Deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted
tax rates in effect in the years in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the
provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to
the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets
will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is
evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies.

The  Company  accounts  for  uncertainty  in  income  taxes  recognized  in  the  consolidated  financial  statements  by  applying  a  two-step
process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will
be  sustained  upon  external  examination  by  the  taxing  authorities.  If  the  tax  position  is  deemed  more  likely  than  not  to  be  sustained,  the  tax
position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that
may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for
income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related
net interest and penalties.

Comprehensive Loss

Comprehensive  loss  includes  net  loss  as  well  as  other  changes  in  stockholders’  equity  (deficit)  that  result  from  transactions  and
economic events other than those with stockholders.  Comprehensive loss is comprised of net loss, foreign currency translation adjustments and
unrealized gains (losses) on marketable securities.

Table of Contents

Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period.  Diluted net
loss per share is computed using the sum of the weighted average number of common shares outstanding during the period, plus the weighted
average  number  of  potential  shares  of  common  stock  from  the  assumed  exercise  of  stock  options,  and  the  assumed  vesting  of  RSUs  and
restricted stock granted by the Company upon its formation, if dilutive.  Since the Company was in a net loss position basic and diluted net loss
per share was the same for each of the periods presented. 

Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP.  Fair value is defined as the exchange price that would be received for
an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between
market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and
minimize  the  use  of  unobservable  inputs.  Financial  assets  and  liabilities  carried  at  fair  value  are  to  be  classified  and  disclosed  in  one  of  the
following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

·

·

·

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or
liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable
or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair
value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

The Company’s cash equivalents, marketable securities and contingent consideration are carried at fair value, determined according to
the fair value hierarchy described above.  The carrying value of the Company’s accounts payable and accrued expenses approximate fair value
due to the short-term nature of these liabilities.

Concentration of Credit Risk and of Significant Suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents
and  marketable  securities.  The  Company  holds  all  cash,  cash  equivalents  and  marketable  securities  balances  at  one  accredited  financial
institution, in amounts that exceed federally insured limits. The Company does not believe that it is subject to unusual credit risk beyond the
normal credit risk associated with commercial banking relationships. 

The Company is dependent on third-party manufacturers to supply drug product, including all underlying components, for its research
and development activities, including preclinical and clinical testing.  These activities could be adversely affected by a significant interruption in
the supply of active pharmaceutical ingredients or other components.

Segment Reporting

Operating segments are components of a company for which separate financial information is available and evaluated regularly by the
chief operating decision maker in assessing performance and deciding how to allocate resources.  The Company has two reportable segments,
therapeutics and contract research, which are primarily based on its operating segments and operating results used to assess performance.  The
therapeutics segment is focused on immuno-inflammatory diseases.  The contract research segment is focused on providing laboratory services to
pharmaceutical and biotech companies looking to supplement their research and development efforts with difficult-to-execute specialty skills and
programs.  The Company does not allocate assets by segment. 

Recently Issued Accounting Pronouncements

In  November  2018,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  ASU  2018-18,  Collaborative  Arrangements  (Topic
808):  Clarifying  the  Interaction  Between  Topic  808  and  Topic  606,  which,  among  other  things,  provides  guidance  on  how  to  assess  whether
certain collaborative arrangement transactions should be accounted for under Topic 606.  The amendments in this ASU are effective for fiscal
years, and interim periods within those fiscal years, beginning after December 15, 2019.  The Company adopted this standard as of January 1,
2020, the impact of which on its consolidated financial statements was not significant. 

In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40).  ASU
2018-15 requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC
350-40 to determine which implementation costs to capitalize as assets or expense as incurred.  The standard will be effective for fiscal years
beginning after December 15, 2019, including interim periods within such fiscal years.  The Company adopted this standard as of January 1,
2020, the impact of which on its consolidated financial statements was not significant. 

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820).  The FASB developed the amendments to ASC
820  as  part  of  its  broader  disclosure  framework  project,  which  aims  to  improve  the  effectiveness  of  disclosures  in  the  notes  to  financial
statements  by  focusing  on  requirements  that  clearly  communicate  the  most  important  information  to  users  of  the  financial  statements.    This
update  eliminates  certain  disclosure  requirements  for  fair  value  measurements  for  all  entities,  requires  public  entities  to  disclose  certain  new
information and modifies some of the existing disclosure requirements.  The standard will be effective for fiscal years beginning after December
15, 2019, including interim periods within such fiscal years.  The Company adopted this standard as of January 1, 2020, the impact of which on
its consolidated financial statements was not significant. 

In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718).  The amendments in this ASU expand
the scope of Topic 718 to include stock-based compensation arrangements with nonemployees except for specific guidance on option pricing
model inputs and cost attribution.  ASU 2018-07 is effective for annual reporting periods beginning after December 31, 2018, including interim
periods within that year.  The Company adopted the provisions of this standard as of January 1, 2019, the impact of which on its consolidated
financial statements was not significant. 

In  February  2016,  the  FASB  issued  ASU  2016-02,  Leases  (Topic  842).    In  July  2018,  the  FASB  issued  ASU  2018-10,  Codification
Improvements to Topic 842, Leases, and 2018-11, Targeted Improvements, which included a number of technical corrections and improvements,
including additional options for transition.  The new standard establishes a right-of-use model that requires a lessee to record a right-of-use asset
and a lease liability on the balance sheet for all leases with terms longer than 12 months.  Leases are classified as either finance or operating, with
classification affecting the pattern of expense recognition in the income statement.  ASU 2016-02 is effective for annual periods beginning after
December  15,  2018,  including  interim  periods  within  those  annual  periods.    The  amendments  in  ASU  2016-02  must  be  applied  to  all  leases
existing at the date a company initially applies the standard. 

The Company adopted the new standard as of January 1, 2019, using the effective date as the date of its initial application, and used the
modified retrospective approach.  In addition, the Company elected the practical expedients permitted under the transition guidance within the
new  standard  which,  among  other  things,  allowed  the  Company  to  carry  forward  the  historical  lease  identification  and  classification.    The
Company also elected the practical expedient to not separate lease and non-lease components, as well as the short-term lease practical expedient
which allowed the Company

100

 
 
 
 
 
 
 
 
 
Table of Contents

to not capitalize leases with terms less than 12 months that do not contain a reasonably certain purchase option.  The Company’s consolidated
financial statements have not been restated, and disclosures required by the new standard have not been provided, for periods before January 1,
2019. 

The adoption of ASU 2016-02 resulted in the Company recording additional assets and liabilities of $2,132 and $2,317, respectively,
upon adoption on January 1, 2019.  The adoption of ASU 2016-02 did not have a material impact on the Company’s consolidated statement of
operations or cash flows.

3. RHOFADE

Disposition - Asset Purchase Agreement with EPI Health, LLC

In  October  2019,  the  Company  entered  into  an  asset  purchase  agreement  with  EPI  Health  pursuant  to  which  the  Company  sold  the

worldwide rights to RHOFADE, which included the assignment of certain licenses for related intellectual property assets (the “Disposition”). 

Pursuant to the asset purchase agreement, EPI Health paid the Company an upfront payment of $35,000  ($1,750 of which was placed in
escrow) and $200 for inventory.  In addition, EPI Health has agreed to pay the Company (i) potential sales milestone payments of up to $20,000
in the aggregate upon the achievement of specified levels of net sales of products as defined in the asset purchase agreement, (ii) a specified high
single-digit royalty calculated as a percentage of net sales, on a product-by-product and country-by-country basis, until the date that the patent
rights related to a particular product, such as RHOFADE, have expired, provided, that with respect to sales of RHOFADE in any territory outside
of the United States,  such royalty shall be paid until the date that the RHOFADE patent rights in the particular country have expired or, if later,
10 years from the date of the first commercial sale of RHOFADE in such country and (iii) 25% of any upfront, license, milestone, maintenance
or fixed payment received by EPI Health in connection with any license or sublicense of the assets transferred in the Disposition in any territory
outside of the United States, subject to specified exceptions.  Finally, EPI Health agreed to assume the Company’s obligation to pay specified
royalties and milestone payments under its existing agreements with Allergan Sales, LLC (“Allergan”), Aspect Pharmaceuticals, LLC and Vicept
Therapeutics, Inc. 

Acquisition – Asset Purchase Agreement with Allergan Sales, LLC

In  November  2018,  the  Company  acquired  the  worldwide  rights  to  RHOFADE,  which  included  an  exclusive  license  to  certain
intellectual  property,  from  Allergan  pursuant  to  an  asset  purchase  agreement.    The  Company  paid  Allergan  upfront  cash  consideration  of
$66,100.    In  addition,  the  Company  agreed  to  pay  Allergan  specified  royalties,  ranging  from  a  mid-single  digit  percentage  to  a  mid-teen
percentage of net sales, subject to specified reductions, limitations and other adjustments, on a country-by-country basis until the date that the
patent  rights  related  RHOFADE  have  expired  or,  if  later,  November  30,  2028.    The  Company  also  agreed  to  assume  the  obligation  to  pay
specified royalties and milestone payments under agreements with Aspect Pharmaceuticals, LLC and Vicept Therapeutics, Inc. 

The  acquisition  of  RHOFADE  was  accounted  for  as  an  asset  acquisition  in  accordance  with  FASB  ASC  805-50,  rather  than  as  a
business combination.  As an asset acquisition, the cost to acquire a group of assets is allocated to the individual assets acquired or liabilities
assumed based on their relative fair values.  The relative fair values of identifiable tangible and intangible assets assumed from the acquisition of
RHOFADE were based on estimates of fair value using assumptions that the Company believes were reasonable.  The Company accounted for
the acquisition of RHOFADE as an asset acquisition because substantially all of the fair value of the assets acquired was concentrated in a single
asset, the RHOFADE product rights.  ASC 805-10-55-5A, which sets forth a screen test, provides that if substantially all of the fair value of the
assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, the assets acquired are not considered to be a
business. 

The following table summarizes the fair value of assets acquired in the acquisition of RHOFADE:

The fair value of finished goods inventory acquired was estimated using net selling price less the costs of disposal and a reasonable
profit  for  the  disposal  efforts.    Raw  material  was  valued  at  current  replacement  cost,  which  approximated  the  seller’s  carrying  value.    The
intangible asset for the RHOFADE product rights was being amortized on a straight-line basis over a period of 10 years.

As of December 31, 2019 and 2018, the Company’s cash equivalents consisted of investments with maturities of less than three months
and included a money market fund and commercial paper, which were valued based upon Level 1 inputs.  As of December 31, 2019 and 2018,
the  Company’s  marketable  securities  consisted  of  investments  with  maturities  of  more  than  three  months  and  included  commercial  paper,
corporate  debt  and  government  obligations,  which  were  valued  based  upon  Level  2  inputs.  In  determining  the  fair  value  of  its  Level  2
investments, the Company relied on quoted prices for identical securities in markets that are not active. These quoted prices were obtained by the
Company  with  the  assistance  of  a  third‑party  pricing  service  based  on  available  trade,  bid  and  other  observable  market  data  for  identical
securities.    Quarterly,  the  Company  compares  the  quoted  prices  obtained  from  the  third‑party  pricing  service  to  other  available  independent
pricing  information  to  validate  the  reasonableness  of  the  quoted  prices  provided.  The  Company  evaluates  whether  adjustments  to  third-party
pricing  is  necessary  and,  historically,  the  Company  has  not  made  adjustments  to  quoted  prices  obtained  from  the  third-party  pricing
service.  During the years ended December 31, 2019 and 2018, there were no transfers between Level 1,  Level 2 and Level 3.  The change in
acquisition-related  contingent  consideration  of  $734  during  the  year  ended  December  31,  2019  was  the  result  of  updates  to  the  Company’s
assumptions as a result of the filing of an Investigational New Drug Application (“IND”) for ATI-450 during the year ended December 31, 2019.

8. Debt

Loan and Security Agreement – Oxford Finance LLC

In  October  2018,  the  Company  entered  into  a  Loan  and  Security  Agreement  (“Loan  Agreement”)  with  Oxford  Finance  LLC,  a
Delaware limited liability company (“Oxford”).  The Loan Agreement provided for up to $65,000 in term loans (the “Term Loan Facility”).  Of
the $65,000, the Company borrowed $30,000 in October 2018.  In October 2019, the Company repaid in full the $30,000 that was outstanding
under the Loan Agreement, together with all accrued and unpaid interest and fees. 

The  Loan  Agreement  provided  for  interest  only  payments  through  November  2021,  followed  by  24  consecutive  equal  monthly
payments of principal and interest in arrears starting on November 2021 and continuing through the maturity date of October 2023.  The Loan
Agreement provided for an annual interest rate equal to the greater of (i) 8.35% and (ii) the 30-day U.S. LIBOR rate plus 6.25%.  The Loan
Agreement also provided for a final payment fee equal to 5.75% of the original principal amount of the term loans drawn under the Term Loan
Facility. 

The carrying value of the Loan Agreement approximated fair value because the interest rate was a floating rate based on the 30-day U.S.

LIBOR rate and was therefore reflective of market rates. 

9. Stockholders’ Equity

Preferred Stock

As of December 31, 2019 and 2018, the Company’s amended and restated certificate of incorporation authorized the Company to issue

10,000,000 shares of undesignated preferred stock.  There were no shares of preferred stock outstanding as of December 31, 2019 and 2018. 

Common Stock

As of December 31, 2019 and 2018, the Company’s amended and restated certificate of incorporation authorized the Company to issue

100,000,000 shares of $0.00001 par value common stock. 

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common
stockholders are entitled to receive dividends, as may be declared by the board of directors, if any, subject to any preferential dividend rights of
any series of preferred stock that may be outstanding.  No dividends have been declared through December 31, 2019. 

At-The-Market Facility

In November 2016, the Company entered into a sales agreement with Cowen and Company, LLC (“Cowen”), pursuant to which Cowen
acted as an agent in connection with sales of the Company’s common stock from time to time under an “at-the-market” equity facility.  In April
2017,  the  Company  sold  635,000  shares  of  common  stock  at  a  weighted  average  price  per  share  of  $31.50,  for  aggregate  gross  proceeds  of
$20,003.  The Company incurred expenses of $691 in connection with the shares issued under the at-the-market sales agreement.  In October
2018, the Company terminated the at-the-market sales agreement with Cowen without having sold any additional shares of common stock.

August 2017 Public Offering

In August 2017, the Company entered into an underwriting agreement pursuant to which the Company issued and sold 3,747,602 shares
of common stock under a registration statement on Form S-3, including the underwriters’ partial exercise of their option to purchase additional
shares.  The shares of common stock were sold to the public at a price of $23.02 per share, for gross proceeds of $86,270. 

The Company paid underwriting discounts and commissions of $5,176 to the underwriters in connection with the offering.  In addition,
the Company incurred expenses of $176 in connection with the offering.  The net offering proceeds received by the Company, after deducting
underwriting discounts and commissions and offering expenses, were $80,918.

10. Stock‑Based Awards

2017 Inducement Plan

In  July  2017,  the  Company’s  board  of  directors  adopted  the  2017  Inducement  Plan  (the  “2017  Inducement  Plan”).    The  2017
Inducement  Plan  is  a  non-shareholder  approved  stock  plan  adopted  pursuant  to  the  “inducement  exception”  provided  under  Nasdaq  listing
rules.  The only employees eligible to receive grants of awards under the 2017 Inducement Plan are individuals who satisfy the standards for
inducement grants under Nasdaq rules, generally including individuals who were not previously an employee or director of the Company. Under
the terms of the 2017 Inducement Plan the Company was permitted to grant up to 1,000,000 shares of common stock pursuant to nonqualified
stock options, stock appreciation rights, restricted stock awards, RSUs, and other stock awards.  All shares of common stock that were eligible
for issuance under the 2017 Inducement Plan after October 1, 2018, including any shares underlying any awards that expire or are otherwise
terminated, reacquired to satisfy tax withholding obligations, settled in cash or repurchased by the Company in the future that would have been
eligible for re-issuance under the 2017 Inducement Plan, were retired. 

2015 Equity Incentive Plan

In September 2015, the Company’s board of directors adopted the 2015 Equity Incentive Plan (the “2015 Plan”), and the Company’s
stockholders approved the 2015 Plan.  The 2015 Plan became effective in connection with the Company’s IPO.  Beginning at the time the 2015
Plan  became  effective,  no  further  grants  may  be  made  under  the  Company’s  2012  Equity  Compensation  Plan,  as  amended  and  restated  (the
“2012 Plan”).  The 2015 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted
stock awards, RSU awards, performance stock awards, cash-based awards and other stock-based awards. The number of shares initially reserved
for issuance under the 2015 Plan was 1,643,872 shares of common stock.  The number of shares of common stock that may be issued under the
2015 Plan will automatically increase on January 1 of each year ending on January 1, 2025, in an amount equal to the lesser of (i) 4.0% of the
shares  of  the  Company’s  common  stock  outstanding  on  December  31  of  the  preceding  calendar  year  or  (ii)  an  amount  determined  by  the
Company’s  board  of  directors.  The  shares  of  common  stock  underlying  any  awards  that  expire,  are  otherwise  terminated,  settled  in  cash  or
repurchased by the Company under the 2015 Plan and the 2012 Plan will be added back to the shares of common stock available for issuance
under the 2015 Plan.  As of December 31, 2019, 817,586 shares remained available for grant under the 2015 Plan.  As of January 1, 2020, the
number of shares of common stock that may be issued under the 2015 Plan was automatically increased by 1,451,997 shares. 

2012 Equity Compensation Plan

Upon the 2015 Plan becoming effective, no further grants can be made under the 2012 Plan.  The Company granted a total of 1,140,524
stock  options  under  the  2012  Plan,  of  which  745,735  and  984,761  were  outstanding  as  of  December  31,  2019  and  2018,  respectively.    Stock
options granted under the 2012 Plan vest over four years and expire after ten years.  As required, the exercise price for the stock options granted
under the 2012 Plan was not less than the fair value of common shares as determined by the Company as of the date of grant.

The Company’s potentially dilutive securities, which included stock options and RSUs, have been excluded from the computation of
diluted net loss per share since the effect would be to reduce the net loss per share.  Therefore, the weighted average number of common shares

13. Income Taxes

The Tax Cuts and Jobs Act of 2017 (the “TCJA”) was enacted on December 22, 2017 and became effective January 1, 2018. The TCJA
made significant changes to U.S. tax law, including lowering U.S. corporate income tax rates, implementing a territorial tax system, imposing a
one-time transition tax on deemed repatriated earnings of foreign subsidiaries and modifying the taxation of other income and expense items.

The TCJA reduced the U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018. Deferred tax assets and liabilities
are  measured  using  enacted  tax  rates  expected  to  apply  to  taxable  income  in  the  years  in  which  those  temporary  differences  are  expected  to
reverse.  As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the TCJA, the Company revalued its deferred
tax liabilities, net as of December 31, 2017.  The impact of revaluation of the deferred tax liabilities, net was $18,507 of income tax expense,
which was more than offset by a reduction in the valuation allowance of $20,344 resulting in a net impact of a $1,837 tax benefit.  The net tax
benefit recorded was primarily the result of tax law changes which impacted the deferred tax liability the Company recorded for

IPR&D related to the acquisition of Confluence.  Under GAAP, IPR&D is an indefinite-lived intangible that is capitalized on the balance sheet,
but which does not have a cost basis under U.S. tax law. 

The TCJA provided for a one-time transition tax on the deemed repatriation of post-1986 undistributed foreign subsidiary earnings and
profits.  The  Company  did  not  have  consolidated  accumulated  earnings  and  profits  attributable  to  its  foreign  subsidiary;  accordingly,  the
Company did not record any income tax expense related to the transition tax. 

Due to the timing of the enactment of the TCJA, the Staff of the SEC issued SAB 118 which provided a measurement period to report
the impact of the TCJA.  During the measurement period, provisional amounts for the effects of the law were able to be recorded to the extent a
reasonable estimate can be made.  To the extent that all information necessary is not available, prepared or analyzed, companies were able to
recognize provisional estimated amounts for a period of up to one year following enactment of the TCJA.  The Company completed its analysis
during the year ended December 31, 2018, and made no adjustments as a result of TCJA under SAB 118. 

During the years ended December 31, 2019,  2018 and 2017, the Company did not record an income tax benefit for net operating losses

incurred in each year due to the uncertainty of realizing a benefit from those items.

Loss before income taxes is allocated as follows:

As  of  December  31,  2019,  the  Company  had  federal  and  state  net  operating  loss  (“NOL”)  carryforwards  of  $326,113  and  $338,822,
respectively, which will begin to expire in 2032.  As of December 31, 2019, the Company also had federal research and development tax credit
carryforwards  of  $7,323  which  will  begin  to  expire  in  2032,  and  state  research  and  development  tax  credit  carryforwards  of  $118  which  will
begin to expire in 2022. The Company also has $1,675 of loss carryforwards in the United Kingdom which can be carried forward indefinitely.
Utilization  of  the  NOLs  and  research  and  development  tax  credit  carryforwards  in  the  United  States  may  be  subject  to  a  substantial  annual
limitation under Section 382 of the Internal Revenue Code of 1986 due to ownership changes that may have occurred previously or that could
occur in the future. These ownership changes may limit the amount of carryforwards that can be utilized annually to offset future taxable income.
 In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain stockholders or public
groups in the stock of a corporation by more than 50% over a three-year period. The Company has completed an analysis under Section 382 for
NOLs generated from July 13, 2012 through December 31, 2018.  Although the Company has experienced Section 382 ownership changes since
2012, the Company has concluded that it should have sufficient ability to utilize NOLs accumulated during the periods tested.  The Company has
not yet determined if a Section 382 ownership change has occurred during the year ended December 31, 2019, or for Confluence prior to the
acquisition.  In addition, the Company may experience ownership changes in the future as a result of subsequent shifts in its stock ownership,
some of which may be outside of the Company’s control. 

The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets.  The Company
considered its history of cumulative net losses incurred since inception, its lack of substantial revenue generated to date, and its forecasted future
operating  losses  and  concluded  that  it  is  more  likely  than  not  that  the  Company  will  not  realize  the  benefits  of  its  deferred  tax
assets.   Accordingly,  a  full  valuation  allowance  has  been  established  against  the  deferred  tax  assets  as  of  December  31,  2019  and  2018.   The
Company evaluates positive and negative evidence of its ability to realize deferred tax assets at each reporting period.

December 31, 2019 and 2018. The Company accrues interest and penalties related to unrecognized tax benefits in income tax expense (benefit)
in the consolidated statement of operations and comprehensive loss.  During each of the years ended December 31, 2019, 2018 and 2017, the
Company recognized expense (benefit) of $0,  $0 and $3, respectively, related to interest and penalties.    

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business,
the  Company  is  subject  to  examination  by  federal  and  state  jurisdictions,  where  applicable.  There  are  currently  no  pending  income  tax
examinations. The Company’s tax years are still open under statute from 2012 to the present.  All open years may be examined to the extent that
tax credit or NOLs are used in future periods.  The Company’s policy is to record interest and penalties related to income taxes as part of its
income tax provision.

In August 2015, the Company entered into an exclusive, worldwide license and collaboration agreement with Rigel Pharmaceuticals,
Inc. (“Rigel”) for the development and commercialization of products containing two specified JAK inhibitors, which the Company refers to as
ATI-501  and  ATI-502.    Under  the  agreement,  the  Company  agreed  to  make  aggregate  payments  of  up  to  $80,000  upon  the  achievement  of
specified development milestones.  During the year ended December 31, 2019, the Company made a milestone payment of $4,000 to Rigel upon
the achievement of a specified development milestone which is included in research and development expenses on the Company’s consolidated
statement of operations.  With respect to any products the Company commercializes under the agreement, the Company will pay Rigel quarterly
tiered royalties on its annual net sales of each product at a high single‑digit percentage of annual net sales, subject to specified reductions, until
the date that all of the patent rights for that product have expired, as determined on a country‑by‑country and product‑by‑product basis or, in
specified countries under specified circumstances, ten years from the first commercial sale of such product. 

In connection with the amendment of the agreement in October 2019, the Company agreed to pay Rigel an amendment fee of $1,500 in
three installments of $500 in January 2020, April 2020 and July 2020, which is included in accrued expenses on the Company’s consolidated
balance  sheet  as  of  December  31,  2019.    In  addition,  the  parties  modified  certain  other  development  milestones,  and  the  Company  agreed  to
increase the potential payments payable upon the achievement of such milestones from $10,000 to $10,500 in the aggregate. 

License, Development and Commercialization Agreement - Cipher Pharmaceuticals Inc.

In April 2018, the Company entered into an exclusive license agreement with Cipher Pharmaceuticals Inc. (“Cipher”) for the rights to
obtain regulatory approval of and commercialize A-101 40% Topical Solution, which the Company marketed under the brand name ESKATA in
the United States, in Canada for the treatment of seborrheic keratosis.  The Company received an upfront payment of $1,000 upon signing of the
agreement with Cipher and $500 upon the achievement of a specified regulatory milestone, both of which are included in other revenue in the
Company’s consolidated statement of operations for the year ended December 31, 2018.  In September 2019, the Company and Cipher mutually
terminated the exclusive license agreement.

Assignment Agreement - Estate of Mickey Miller and
Finder’s Services Agreement - KPT Consulting, LLC

In August 2012, the Company entered into an assignment agreement with the Estate of Mickey Miller (the “Miller Estate”) under which
the Company acquired some of the intellectual property rights covering A-101 45% Topical Solution and ESKATA. In connection with obtaining
the  assignment  of  the  intellectual  property  from  the  Miller  Estate,  the  Company  also  entered  into  a  separate  finder’s  services  agreement  with
KPT  Consulting,  LLC.    Under  the  terms  of  the  finder’s  services  agreement,  the  Company  made  a  milestone  payment  of  $1,000  upon  the
achievement  of  a  specified  regulatory  milestone  in  April  2017,  and  a  milestone  payment  of  $1,500  upon  the  achievement  of  a  specified
commercial  milestone  in  May  2018.    The  payments  were  recorded  as  general  and  administrative  expenses  in  the  Company’s  consolidated
statement of operations.  

Under  the  finder’s  services  agreement  the  Company  is  obligated  to  make  an  additional  milestone  payment  of  $3,000  upon  the
achievement of a specified commercial milestone.  Under each of the assignment agreement and the finder’s services agreement, the Company is
obligated  to  pay  royalties  on  sales  of  ESKATA  and  any  related  products,  at  low  single-digit  percentages  of  net  sales,  subject  to  reduction  in
specified circumstances.  The Company incurred an aggregate expense of $14, $112 and $0 related to royalty payments under these agreements
during the years ended December 31, 2019, 2018 and 2017, respectively.  Both agreements will terminate upon the expiration of the last pending,
viable  patent  claim  of  the  patents  acquired  under  the  assignment  agreement,  but  no  sooner  than  15  years  from  the  effective  date  of  the
agreements.

Stock Purchase Agreement - Vixen Pharmaceuticals, Inc. and License Agreement - Columbia University

In March 2016, the Company entered into a stock purchase agreement (the “Vixen Agreement”) with Vixen, JAK1, LLC, JAK2, LLC
and JAK3, LLC (together, the “Selling Stockholders”) and Shareholder Representative Services LLC, solely in its capacity as the representative
of  the  Selling  Stockholders.  Pursuant  to  the  Vixen  Agreement,  the  Company  acquired  all  shares  of  Vixen’s  capital  stock  from  the  Selling
Stockholders. Following the acquisition of Vixen, Vixen became a wholly-owned subsidiary of the Company. The Company is obligated to make
annual payments of $100 each year through March 2022, with such amounts being creditable against specified future payments that may be paid
under the Vixen Agreement.

The Company is obligated to make aggregate payments of up to $18,000 to the Selling Stockholders upon the achievement of specified
pre-commercialization milestones for three products covered by the Vixen patent rights in the United States, the European Union and Japan, and
aggregate  payments  of  up  to  $22,500  upon  the  achievement  of  specified  commercial  milestones  for  products  covered  by  the  Vixen  patent
rights.  With respect to any covered products that the Company commercializes under the Vixen Agreement, the Company is obligated to pay
low single-digit royalties on net sales, subject to specified reductions, limitations and other adjustments, until the date that all of the patent rights
for that product have expired, as determined on a country-by-country and product-by-product basis or, in specified circumstances, ten years from
the first commercial sale of such product. If the Company sublicenses any of Vixen’s patent rights and know-how acquired pursuant to the Vixen
Agreement,  the  Company  will  be  obligated  to  pay  a  portion  of  any  consideration  the  Company  receives  from  such  sublicenses  in  specified
circumstances.    

As a result of the transaction with Vixen, the Company became party to the Exclusive License Agreement, by and between Vixen and
the  Trustees  of  Columbia  University  in  the  City  of  New  York  (“Columbia”),  dated  as  of  December  31,  2015  (as  amended,  the  “License
Agreement”).  Under  the  License  Agreement,  the  Company  is  obligated  to  pay  Columbia  an  annual  license  fee  of  $10,  subject  to  specified
adjustments for patent expenses incurred by Columbia and creditable against any royalties that may be paid under the License Agreement. The
Company is also obligated to pay up to an aggregate of $11,600 upon the achievement of specified commercial milestones, including specified
levels of net sales of products covered by Columbia patent rights and/or know-how, and royalties at a sub-single-digit percentage of annual net
sales  of  products  covered  by  Columbia  patent  rights  and/or  know-how,  subject  to  specified  adjustments.  If  the  Company  sublicenses  any  of
Columbia’s  patent  rights  and  know-how  acquired  pursuant  to  the  License  Agreement,  it  will  be  obligated  to  pay  Columbia  a  portion  of  any
consideration received from such sublicenses in specified circumstances. The royalties, as determined on a country-by-country and product-by-
product basis, are payable until the date that all of the patent rights for that product have expired, the expiration of any market exclusivity period
granted by a regulatory body or, in specified circumstances, ten years from the first commercial sale of such product. The License Agreement
terminates on the date of expiration of all royalty obligations thereunder unless earlier terminated by either party for a

material breach, subject to a specified cure period. The Company may also terminate the License Agreement without cause at any time upon
advance written notice to Columbia.

16. Retirement Savings Plan

The  Company  has  a  defined  contribution  savings  plan  under  Section  401(k)  of  the  Internal  Revenue  Code.  This  plan  covers
substantially  all  employees  who  meet  minimum  age  and  service  requirements  and  allows  participants  to  defer  a  portion  of  their  annual
compensation on a pre-tax basis. Company contributions to the plan may be made at the discretion of the Company’s board of directors. The
Company  has  elected  to  match  100%  of  employee  contributions  to  the  401(k)  Plan  up  to  4%  of  the  employee’s  earnings,  subject  to  certain
limitations.  Company contributions under the 401(k) Plan were $740,  $662, and $270 for the years ended December 31, 2019, 2018 and 2017,
respectively. 

17. Restructuring Charges

In  September  2019,  the  Company  announced  the  completion  of  a  strategic  review  and  its  decision  to  refocus  on  its  immuno-
inflammatory  development  programs  and  to  actively  seek  partners  for  its  commercial  products.    As  a  result,  the  Company  terminated  63
employees (“terminated employees”) and gave notice to an additional 23 employees (“noticed employees”) who were asked to provide transition
services through termination dates ranging between 4 to 10 months from the date notice was given.  The terminated employees were entitled to
receive  cash  severance  payments  as  well  as  cash  payments  in  lieu  of  sixty  days’  notice  required  by  the  Worker  Adjustment  and  Retraining
Notification Act (the “WARN Act”).  The noticed employees are entitled to receive one-time cash severance payments which are not contingent
upon providing additional services to the Company.  In addition, certain noticed employees can earn retention bonuses if they continue to be
employed  by  the  Company  through  certain  termination  dates.    The  Company  recorded  a  restructuring  charge  for  the  one-time  severance  and
WARN Act payments, which was triggered immediately upon either terminating or giving notice to the impacted employees.  The Company is
expensing the cost of retention bonuses for noticed employees over their respective service terms.  During the year ended December 31, 2019,
the Company recognized aggregate expenses of $2,748 and made payments of $2,316 related to termination benefits for employees explained
above.  The Company committed to paying up to $339 for contingent retention bonuses, of which $208 was accrued, as of December 31, 2019.

The  Company  relied  on  Allergan  to  distribute  RHOFADE  on  its  behalf  pursuant  to  the  terms  of  a  transition  services
agreement.  Accounts receivable, net as of December 31, 2019 and 2018 included $4,966 and $3,838, respectively, related to amounts invoiced
by Allergan for sales of RHOFADE. 

As a result of the Company’s decision to actively seek partners for its commercial products, the Company terminated the finance leases
for its fleet vehicles and recognized a loss on lease termination of $248 in the year ended December 31, 2019, which is included in other income,
net in the Company’s consolidated statement of operations.

During the year ended December 31, 2019, the Company performed an impairment analysis of the RHOFADE intangible asset due to its
decision  to  discontinue  commercial  operations  and  actively  seek  a  commercialization  partner  for  RHOFADE.    The  Company’s  impairment
analysis, which primarily utilized a third-party indication of fair value, resulted in a fair value for the RHOFADE intangible asset which was less
than  its  carrying  value.   As  a  result,  the  Company  recorded  an  impairment  charge  of  $27,638  to  adjust  the  carrying  value  of  the  RHOFADE
intangible asset to its net realizable value. 

19. Segment Information

The Company has two reportable segments, therapeutics and contract research.  The therapeutics segment is focused on identifying and
developing  innovative  therapies  to  address  significant  unmet  needs  for  immuno-inflammatory  diseases.  The  contract  research  segment  earns
revenue  from  the  provision  of  laboratory  services  to  clients  through  Confluence,  the  Company’s  wholly-owned  subsidiary.    Contract  research
revenue  is  generally  evidenced  by  contracts  with  clients  which  are  on  an  agreed  upon  fixed-price,  fee-for-service  basis.    Corporate  and  other
includes general and administrative expenses as well as eliminations of intercompany transactions.  The Company does not report balance sheet
information by segment since it is not reviewed by the chief operating decision maker, and all of the Company’s tangible assets are held in the
United States. 

The Company’s results of operations by segment for the years ended December 31, 2019, 2018 and 2017 are summarized in the tables

20. Legal Proceedings

Securities Class Action

On July 30, 2019, plaintiff Linda Rosi (“Rosi”) filed a putative class action complaint captioned Rosi v. Aclaris Therapeutics, Inc., et al.
in the U.S. District Court for the Southern District of New York against the Company and certain of its executive officers.  The complaint alleges
that  the  defendants  violated  federal  securities  laws  by,  among  other  things,  failing  to  disclose  an  alleged  likelihood  that  regulators  would
scrutinize advertising materials related to ESKATA and find that the materials minimized the risks or overstated the efficacy of the product.  The
complaint seeks unspecified compensatory damages on behalf of Rosi and all other persons and entities that purchased or otherwise acquired the
Company’s securities between May 8, 2018 and June 20, 2019. 

On September 5, 2019, an additional plaintiff, Robert Fulcher (“Fulcher”), filed a substantially identical putative class action complaint

captioned Fulcher v. Aclaris Therapeutics, Inc., et al. in the same court against the same defendants.

On  November  6,  2019,  the  court  consolidated  the  Rosi  and  Fulcher  actions  (together,  the  “Consolidated  Securities  Action”)  and

appointed Fulcher “lead plaintiff” for the putative class. 

On  January  24,  2020,  Fulcher  filed  a  consolidated  amended  complaint  in  the  Consolidated  Securities  Action,  naming  two  additional
executive officers as defendants, extending the putative class period to August 12, 2019, and adding allegations concerning, among other things,
alleged  statements  and  omissions  throughout  the  putative  class  period  concerning  ESKATA’s  risks,  tolerability  and  effectiveness.    The
defendants’ deadline to answer, move against or otherwise respond to the consolidated amended complaint is March 27, 2020.

The Company and the other defendants dispute plaintiffs’ claims in the Consolidated Securities Action and intend to defend the matter

vigorously.

Stockholder Derivative Action

On November 15, 2019, plaintiff Keith Allred (“Allred”) filed a derivative stockholder complaint captioned Allred v. Walker et al. in the
U.S.  District  Court  for  the  Southern  District  of  New  York  against  certain  of  the  Company’s  directors  and  executive  officers.   The  complaint
alleges that the defendants, among other things, breached their fiduciary duties as directors and/or officers in connection with the claims alleged
in the Consolidated Securities Action.  The complaint seeks, among other things, unspecified compensatory damages on behalf of the Company. 

On November 25, 2019, an additional plaintiff, Bruce Brown (“Brown”), filed a substantially identical complaint captioned Brown v.

Walker et al. in the same court against the same defendants.

On  December  12,  2019,  the  court  consolidated  the  Allred  and  Brown  actions  under  the  caption  In  re  Aclaris  Therapeutics,  Inc.
Derivative Litigation (the “Consolidated Derivative Action”) and directed that future derivative cases filed in or transferred to the court arising
out  of  substantially  the  same  transactions  or  events  be  similarly  consolidated.    Thereafter,  on  January  11,  2020,  the  court  stayed  –  subject  to
certain conditions – all deadlines in the Consolidated Derivative Action pending resolution of the defendants’ anticipated motion to dismiss the
Consolidated Securities Action.

The defendants dispute plaintiffs’ claims in the Consolidated Derivative Action and intend to defend the matter vigorously.

Patent Infringement

On October 8, 2019, the Company, together with Allergan, Inc., filed a patent infringement lawsuit in the U.S. District Court for the
District  of  Delaware  against Taro  Pharmaceuticals,  Inc.  (“Taro”),  related  to  an  Abbreviated  New  Drug  Application  (“ANDA”)  that  Taro  filed
with the FDA to market a generic version of RHOFADE.  The lawsuit claims infringement of U.S. Patent Nos. 7,812,049, 8,420,688, 8,815,929,
9,974,773 and 10,335,391, which are listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known
as the Orange Book, for RHOFADE.  The Company received a Paragraph IV Notice Letter from Taro dated August 28, 2019, advising that Taro
had submitted an ANDA to the FDA seeking approval from the FDA to manufacture and market a generic version of RHOFADE prior to the
expiration of the Orange Book-listed patents. Under the agreement with EPI Health for the purchase of RHOFADE, EPI Health agreed to file a
motion to be substituted for the Company as a plaintiff party and has agreed to reimburse the Company for its reasonable fees and expenses so
long as it remained a plaintiff party.  On December 3, 2019, EPI Health was substituted for the Company as a plaintiff party.

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

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under  the  supervision  of  and  with  the  participation  of  our  management,  including  our  chief  executive  officer,  who  is  our  principal
executive officer, and our chief financial officer, who is our principal financial officer, we conducted an evaluation of the effectiveness of our
disclosure controls and procedures as of December 31, 2019, the end of the period covered by this Annual Report. The term “disclosure controls
and procedures,” as set forth in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act,
means controls and other procedures of a company that are designed to provide reasonable assurance that information required to be disclosed by
a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods
specified in the rules and forms promulgated by the SEC. Disclosure controls and procedures include, without limitation, controls and procedures
designed  to  ensure  that  information  required  to  be  disclosed  by  a  company  in  the  reports  that  it  files  or  submits  under  the  Exchange  Act  is
accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate
to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed
and  operated,  can  provide  only  reasonable  assurance  of  achieving  their  objectives,  and  management  necessarily  applies  its  judgment  in
evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as
of  December  31,  2019,  our  chief  executive  officer  and  chief  financial  officer  concluded  that,  as  of  such  date,  our  disclosure  controls  and
procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-
15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2019 that has materially affected, or is reasonably
likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting and Attestation Report of the Registered Public Accounting Firm

Our  management  is  responsible  for  establishing  and  maintaining  an  adequate  system  of  internal  control  over  financial  reporting,  as
defined in Rule 13a-15(f) of the Exchange Act. Management conducted an assessment of our internal control over financial reporting based on
the framework established in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated
Framework.  Based on the assessment, management concluded that, as of December 31, 2019, our internal control over financial reporting was
effective.

This  Annual  Report  does  not  include  an  attestation  report  of  our  registered  public  accounting  firm  regarding  internal  control  over
financial reporting as required by Section 404(b) of the Sarbanes-Oxley Act of 2002. Because we qualify as an emerging growth company under
the JOBS Act, management's report was not subject to attestation by our independent registered public accounting firm.

Exhibit 4.2

DESCRIPTION OF ACLARIS THERAPEUTICS, INC. CAPITAL STOCK

The following description of the common stock of Aclaris Therapeutics, Inc., or the Company, is a summary and does not purport to be
complete. This summary is qualified in its entirety by reference to the provisions of the Delaware General Corporation Law, or the DGCL,
and the complete text of the Company’s amended and restated certificate of incorporation, or the certificate of incorporation, and amended
and restated bylaws or the bylaws, which are incorporated by reference as Exhibits 3.1 and 3.2, respectively of the Company’s Annual
Report on Form 10-K to which this description is also an exhibit. The Company encourages you to read that law and those documents
carefully. 

Common Stock

Under the certificate of incorporation, the Company authorized to issue up to 100,000,000 shares of common stock, $0.00001 par value

per share, and 10,000,000 shares of preferred stock, $0.00001 par value per share, all of which shares of preferred stock are undesignated.
The Company’s board of directors may establish the rights and preferences of the preferred stock from time to time.

Voting Rights

Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the

election of directors. Under the certificate of incorporation and the bylaws, common stockholders do not have cumulative voting rights.
Because of this, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the
directors standing for election, if they should so choose.

Dividends

Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of common stock are entitled to receive

ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds.

Liquidation

In the event of the Company’s liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the
net assets legally available for distribution to stockholders after the payment of all of debts and other liabilities and the satisfaction of any
liquidation preference granted to the holders of any then-outstanding shares of preferred stock.

Rights and Preferences

Holders of common stock have no preemptive, conversion or subscription rights and there are no redemption or sinking fund

provisions applicable to the common stock. The rights, preferences and privileges of the holders of common stock are subject to, and may
be adversely affected by, the rights of the holders of shares of any series of preferred stock that the Company may designate in the future.

Anti-Takeover Provisions

Section 203 of the DGCL

The Company is subject to Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business

combination with any interested stockholder for a period of three years after the date that such stockholder became an interested
stockholder, with the following exceptions:

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(cid:0)                  before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted

in the stockholder becoming an interested stockholder;

(cid:0)                  upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder
owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of
determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, those shares
owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have
the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

(cid:0)                  on or after such date, the business combination is approved by the board of directors and authorized at an annual or special

meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock
that is not owned by the interested stockholder.

In general, Section 203 defines a “business combination” to include the following:

(cid:0)                  any merger or consolidation involving the corporation and the interested stockholder;
(cid:0)                  any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;
(cid:0)                  subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the

corporation to the interested stockholder;

(cid:0)                  any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series

of the corporation beneficially owned by the interested stockholder; or

(cid:0)                  the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or

through the corporation.

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and

associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more
of the outstanding voting stock of the corporation.

Certificate of Incorporation and Bylaws

The certificate of incorporation provides for the Company’s board of directors to be divided into three classes with staggered three-year

terms. Only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the
remainder of their respective three-year terms. Because the Company’s stockholders do not have cumulative voting rights, stockholders
holding a majority of the shares of common stock outstanding will be able to elect all of the Company’s directors. The certificate of
incorporation and bylaws also provide that directors may be removed by the stockholders only for cause upon the vote of 66 2/3% or more
of outstanding common stock. Furthermore, the authorized number of directors may be changed only by resolution of the board of
directors, and vacancies and newly created directorships on the board of directors may, except as otherwise required by law or determined
by the board, only be filled by a majority vote of the directors then serving on the board, even though less than a quorum.

The certificate of incorporation and bylaws also provide that all stockholder actions must be effected at a duly called meeting of
stockholders and will eliminate the right of stockholders to act by written consent without a meeting. The bylaws also provide that only the
Company’s chairman of the board, chief executive officer or the board of directors pursuant to a resolution adopted by a majority of the
total number of authorized directors may call a special meeting of stockholders.

The bylaws also provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for

election as directors at a meeting of stockholders must provide timely advance notice in writing, and specify requirements as to the form
and content of a stockholder’s notice.

The certificate of incorporation and bylaws provide that the stockholders cannot amend many of the provisions described above except

by a vote of 66 2/3% or more of outstanding common stock.

 
 
 
 
 
 
 
 
 
The combination of these provisions make it more difficult for the Company’s existing stockholders to replace the board of directors as

well as for another party to obtain control of the Company by replacing its board of directors. Since the Company’s board of directors has
the power to retain and discharge the Company’s officers, these provisions also make it more difficult for existing stockholders or another
party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for the Company’s
board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change
the Company’s control.

These provisions are intended to enhance the likelihood of continued stability in the composition of the Company’s board of directors

and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce
the Company’s vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such
provisions could have the effect of discouraging others from making tender offers for the Company’s shares and may have the effect of
delaying changes in its control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of the
Company’s stock that could result from actual or rumored takeover attempts. The Company believes that the benefits of these provisions,
including increased protection of its potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or
restructure the company, outweigh the disadvantages of discouraging takeover proposals, because negotiation of takeover proposals could
result in an improvement of their terms.

be  modified  by  Employer  from  time  to  time;  provided,  however,  that  Executive  has  provided  Employer  with
documentation of such expenses in accordance with the Employer’s expense reimbursement policies and applicable
tax  requirements.    For  the  avoidance  of  doubt,  to  the  extent  that  any  reimbursements  payable  to  Executive  are

December  31  of  the  year  following  the  year  in  which  the  expense  was  incurred,  (b)  the  amount  of  expenses
reimbursed  in  one  year  will  not  affect  the  amount  eligible  for  reimbursement  in  any  subsequent  year,  and  (c)  the

revised  or  deleted  from  time  to  time  in  Employer’s  sole  discretion,  subject  to  and  on  a  basis  consistent  with  the
terms, conditions and overall administration of such plans and programs. All matters of eligibility for coverage or
benefits  under  any  benefit  plan  shall  be  determined  in  accordance  with  the  provisions  of  such  plan.    Employer
retains  the  unilateral  right  to  amend,  modify  or  terminate  any  of  its  employee  benefit  plans  and  programs  at  any
time.

other amounts as may be required by law.

successive one (1) year periods (the Initial Term, together with any subsequent employment period being referred to

of death.

3.1.1

 Death. In the event of Executive’s death, Executive’s employment will terminate on the date

3.1.2

  Disability.  In  the  event  of  Executive’s  Disability  (as  hereinafter  defined),  Employer  will
have the option to terminate Executive’s employment by giving a notice of termination to Executive. The notice of
termination shall specify the date of termination, which date shall not be earlier than thirty (30) calendar days after
the notice of termination is given. For purposes of this Employment Agreement, “Disability” means the failure or
inability of Executive to substantially perform, with or without reasonable accommodation, his duties hereunder for
an  aggregate  of  ninety  (90)  calendar  days  during  any  consecutive  three  hundred  sixty-five  (365)  day  period  as  a
result  of  a  physical  or  mental  illness  or  injury,  as  determined  in  good  faith  by  the  Board  upon  the  advice  of  an
independent physician experienced in treating the condition(s) allegedly giving rise to the disability.  This definition
shall be interpreted and applied consistent with the Americans with Disabilities Act, the Family and Medical Leave
Act, and other applicable law.

3.1.3

 Termination by Employer for Cause. Employer may, at its option, terminate Executive’s
employment  for  Cause  by  unilateral  action  of  the  Board  of  Directors  upon  giving  a  notice  of  termination  to
Executive. “Cause” shall mean (i) Executive’s conviction of, or guilty plea to, a crime of moral turpitude (whether
or  not  a  felony)  or  a  felony  (other  than  traffic  violations);  (ii)  any  act(s)  or  omission(s)  by  Executive  which
constitutes  gross  negligence  or  a  material  breach  of  Executive’s  duty  of  loyalty;  (iii)  any  material  breach  by
Executive  of  Employer’s  personnel  policies,  including  those  prohibiting  acts  of  discrimination,  harassment  or
retaliation;  (iv)  any  act  constituting  dishonesty,  fraud,  immoral  or  disreputable  conduct;  (v)  refusal  to  follow  or
implement a clear and reasonable directive of Employer; (vi) breach of fiduciary duty; or (vii) a material violation
or breach by Executive of this Employment Agreement (other than an event described in the foregoing clauses (i)
through (vi)) or any other agreement between the parties.

3.1.4

  Without  Cause  By  Employer.  Employer  may,  at  its  option,  terminate  Executive’s
employment  for  any  reason  whatsoever  (other  than  for  the  other  reasons  set  forth  above  in  this  Section  3.1  that
would constitute “Cause” to terminate) by giving a notice of termination to Executive, and Executive’s employment
shall  terminate  on  the  later  of  the  date  the  notice  of  termination  is  given  or  the  date  set  forth  in  such  notice  of
termination.

3.1.5

 By Executive. Executive may, at any time, terminate Executive’s employment for any reason
whatsoever by giving a notice of termination to Employer. Executive’s employment shall terminate on the earlier of
(i)  the  date,  following  the  date  of  the  notice  of  termination,  upon  which  a  suitable  replacement  for  Executive  is
found  by  the  Employer  or  upon  which  Employer  makes  a  determination,  in  its  sole  discretion,  that  Executive’s
duties shall be undertaken by other employees of Employer, (ii) thirty (30) calendar days after the date of receipt by
Employer of the notice of termination, or (iii) such earlier date as the Employer and Executive shall agree.

 Termination Upon Non-Renewal. Either party may terminate this Employment Agreement
and Executive’s employment hereunder by providing the other party notice in accordance with Section 2.4 above, in
which case this Employment Agreement and

3.1.6

4

 
 
Executive’s employment hereunder shall terminate on the last date of the Initial Term or the Employment Term, as
the case may be. For the avoidance of doubt, Executive shall continue to be employed by Employer, on the same
terms  and conditions as set forth in this Employment Agreement during the ninety (90)-day notice period provided
by  either  party  to  the  other  party  in  accordance  with  Section  2.4  above,  unless,  Employer,  in  its  sole  discretion
determines that it does not want Executive to continue to work for Employer, in any capacity, during such notice
period. In such event, Employer shall pay Executive all compensation in accordance with Section 3.2.3.

  For  Good  Reason  by  Executive.  Executive  may,  at  his  option,  terminate  Executive’s
employment for “Good Reason” by giving a notice of termination to Employer in the event that, in the absence of
events that would support a termination of Executive for Cause:

3.1.7

  there  is  a  material  failure  of  Employer  (or  successor  employer)  to  pay
Executive’s  salary  or  additional  compensation  or  benefits  hereunder  in  accordance  with  this  Employment
Agreement;

(i)

written consent;

(ii)

  Executive’s  annual  Base  Salary  is  materially  decreased  without  his  prior

responsibilities set forth in Executive’s job description, without Executive’s prior written consent;

(iii)

 Executive  is  assigned  duties  substantially  inconsistent  with  his  title  and  the

 Executive’s place of employment is changed to a location that is greater than
fifty (50) miles from Executive’s current place of employment which is contemplated to be 101 Lindenwood Drive,
Suite 400, Malvern, Pennsylvania 19355; or

(iv)

Agreement.

(v)

  any  other  material  violation  or  breach  by  Employer  of  this  Employment

Notwithstanding the foregoing, none of the events described in clauses (i) through (v) above shall constitute Good
Reason unless Executive shall have notified Employer in writing describing the event which constitute Good Reason
within  thirty  (30)  days  after  Executive  first  becomes  aware  of  such  event  and  then  only  if  Employer  and/or  its
subsidiaries  shall  have  failed  to  reasonably  cure  such  events,  if  curable,  within  thirty  (30)  days  after  Employer’s
receipt of such written notice and Executive elects to terminate his employment as a result within thirty (30) days
following the end of such thirty (30) day period (assuming, for the avoidance of doubt, that Employer does not elect
to cure).

3.2

  Certain  Obligations  of  Employer  Following  Termination  of  Executive’s  Employment.
Following the termination of Executive’s employment under the circumstances described below, Employer will pay
to  Executive,  subject  to  standard  federal  and  state  payroll  withholding  requirements  and  in  accordance  with  its
regular  payroll  practices,  the  following  compensation  and  provide  the  following  benefits  (provided  that  the
continuing  payments  of  Executive’s  then-current  salary,  as  described  below,  shall  occur  no  less  frequently  than
monthly):

5

 
 
3.2.1

 Death; Disability; Termination by Employer Without Cause or by Executive for Good
Reason. In the event that Executive’s employment is terminated by Employer pursuant to Section 3.1.1 (“Death”),
Section  3.1.2  (“Disability”),  Section  3.1.4  (“Without  Cause  by  Employer”)  or  by  Executive  pursuant  to  Section
3.1.7  (“Termination  by  Executive  for  Good  Reason”)  hereof,  and  Executive,  or  his  estate,  as  the  case  may  be,
executes and does not revoke a separation agreement containing a release upon such termination, in a form provided
by the Employer, of any and all claims against Employer and all related parties with respect to all matters arising out
of Executive’s employment by Employer, or the termination thereof (the “Release”) in accordance with Section 3.7,
Executive,  or  his  estate,  as  the  case  may  be,  shall  be  entitled  to  the  following  payments  and  benefits,  which
payments and benefits shall be paid in accordance with this Section 3.2.1 and Section 3.7:

  Continuing  payments  of  Executive’s  then-current  salary  for  the  Severance
Period,  as  defined  in  Section  3.5  herein,  payable  subject  to  standard  federal  and  state  payroll  withholding
requirements in accordance with Employer’s regular payroll practices on Employer’s normal payroll schedule over
the Severance Period, subject to Section 3.7;  

(i)

(ii)

 Employer shall pay to Executive a lump sum payment equal to the gross sum
of any bonuses or portion thereof for any preceding year or for the year of termination which have been approved by
Employer,  but  has  not  been  received  by  Executive  prior  to  the  effective  date  of  termination,  less  applicable
deductions and withholdings paid in accordance with Section 2.2 but in no event later than two and one-half (2 1/2)
months following the end of the fiscal year to which it relates. For the avoidance of doubt, (x) Executive does not
have to be employed by Employer on the date such bonuses are approved by Employer to receive such bonuses; and
(y) this provision shall not be construed as guaranteeing the payment of a bonus for such year(s);

(iii)

 So long as Executive is eligible, and so long as Executive remains eligible,
for and upon his timely election of coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985,
or, if applicable, state or local insurance laws (“COBRA”), Employer will continue to pay, directly to the healthcare
provider when due, 100% of the medical, vision and dental coverage premiums (including employee contributions,
if any) until the earlier of (i) the end of the Severance Period; or (ii) the date when Executive becomes eligible for
substantially  equivalent  health  insurance  coverage  in  connection  with  new  employment  (the  “COBRA  Payment
Period”);  provided that Executive must immediately notify Employer in the event Executive becomes eligible for
coverage  under  another  employer’s  group  health  plan  during  the  COBRA  Payment  Period;  and  provided  further
that, if at any time Employer determines, in its sole discretion, that the payment of the COBRA premiums would
result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Code or any statute or regulation of
similar effect (including but not limited to the 2010 Patient Protection and Affordable Care Act, as amended by the
2010  Health  Care  and  Education  Reconciliation  Act),  then  in  lieu  of  providing  the  COBRA  premiums  for  the
remainder of the COBRA Payment Period, Employer will instead pay Executive on the first day of each month of
the remainder of the COBRA Payment Period, a fully taxable cash payment equal to the COBRA premiums for that
month, subject to applicable tax withholdings, for the remainder of the COBRA Payment Period; and

6

 
 
 In  the  event  such  termination  of  employment  occurs  on  or  within  three  (3)
months  prior  to  or  within  twelve  (12)  months  following  the  effective  date  of  a  Change  of  Control  (as  defined
herein), Executive shall be entitled to the additional following payments and benefits:

(iv)

  Continuing  payments  of  Executive’s  then-current  salary  for  an
additional six (6) months following the end of the Severance Period, payable subject to standard federal and state
payroll  withholding  requirements  in  accordance  with  Employer’s  regular  payroll  practices  on  Employer’s  normal
payroll schedule over the six (6) month period immediately following the end of the Severance Period, subject to
Section 3.7;

(1)

 Continued payment of Executive’s COBRA premiums directly to the
healthcare provider for an additional six (6) months following the end of the Severance Period, or if earlier, until the
date  when  Executive  becomes  eligible  for  substantially  equivalent  health  insurance  coverage  in  connection  with
new employment, subject to the terms, conditions and payment provisions set forth in Section 3.2.1(iii); and

(2)

(3)

 In the event such termination of employment occurs (A) on or within
three (3) months prior to  the effective date of a Change of Control (as defined herein), all unvested stock options
and other equity awards held by Executive and outstanding on the effective date of termination shall become fully
vested on the effective date of the Change of Control, or (B) within twelve (12) months following the effective date
of a Change of Control, provided that any surviving corporation or acquiring corporation assumes Executive’s stock
options  and/or  other  equity  awards,  as  applicable,  or  substitutes  similar  stock  options  or  equity  awards  for
Executive’s  stock  options  and/or  equity  awards,  as  applicable,  in  accordance  with  the  terms  of  Employer’s
 applicable equity incentive plans, all such unvested stock options and other equity awards held by Executive and
outstanding on the effective date of termination shall become fully vested on the date of such termination.  

For purposes of this Agreement, “Change of Control” means, in each case as approved
by the Board and the requisite stockholders of Employer, (i) any consolidation or merger of Employer with or into
any other corporation or other entity or person, or any other corporate reorganization, in which the stockholders of
Employer immediately prior to such consolidation, merger or reorganization, own, in the aggregate, less than 50%
of the surviving entity’s voting power and/or outstanding capital stock immediately after such consolidation, merger
or reorganization, or any transaction or series of related transactions (including any transaction which results from
an option agreement or binding letter of intent with a third party) to which Employer or any of its stockholders is a
party  in  which  in  excess  of  50%  of  Employer’s  voting  power  and/or  outstanding  capital  stock  is  transferred,  or
pursuant to which any person or group of affiliated persons obtains in excess of 50% of Employer’s voting power
and/or outstanding capital stock, excluding any consolidation or merger effected exclusively to change the domicile
of  Employer;  or  (ii)  any  sale,  lease  or  other  disposition  (including  through  a  Board  and  stockholder  approved
division or spin-off transaction) of all or substantially all of the assets of Employer and/or any of its subsidiaries or
any  sale,  lease,  exclusive  license  (or  substantially  exclusive  license  or  agreement)  or  other  disposition  of  all  or
substantially  all  of  Employer’s  intellectual  property,  as  reasonably  determined  based  upon  the  potential  earning
power of the assets or intellectual property; provided, however that none of the following shall

7

 
 
constitute  a  Change  of  Control:  (A)  transfers  of  capital  stock  by  an  existing  stockholder  as  a  result  of  death  or
otherwise  for  estate  planning  purposes  or  to  such  stockholder’s  affiliates  or  to  any  of  Employer’s  other  existing
stockholders, and (B) issuances of equity securities of Employer in connection with financings for working capital
and other general corporate purposes.

3.2.2

  Termination  by  Executive  Other  than  For  Good  Reason:  Termination  Upon  Non-
Renewal by Executive; Termination by Employer for Cause. In the event Executive’s employment is terminated
by  Executive  other  than  for  Good  Reason  pursuant  to  Section  3.1.5  hereof  (“By  Executive”)  or  by  Executive
pursuant  to  Section  3.1.6  hereof  (“Termination  Upon  Non-Renewal”)  or  by  Employer  pursuant  to  Section  3.1.3
hereof  (“Termination  by  Employer  for  Cause”),  Executive  shall  be  entitled  to  no  further  compensation  or  other
benefits under this Employment Agreement except as to that portion of any unpaid salary and other benefits accrued
and  earned  by  him  hereunder  up  to  and  including  the  effective  date  of  such  termination  and  to  offer  COBRA
coverage at Executive’s cost pursuant to applicable law.

3.2.3

 Termination  Upon  Non  Renewal  by  Employer.  In  the  event  Executive’s  employment  is
terminated by Employer pursuant to Section 3.1.6 hereof, then during the ninety (90)-day notice period of Section
2.4,  Employer  shall  continue  to  pay  to  Executive  his  then-current  annual  Base  Salary  and  benefits  subject  to
standard  federal  and  state  payroll  withholding  requirements  and  in  accordance  with  Employer’s  regular  payroll
practices and no later than the effective date of termination of employment, Employer shall pay to Executive any
unpaid salary accrued and earned by him up to and including the effective date of termination.  In addition, in the
event Executive’s employment is terminated by Employer pursuant to Section 3.1.6 hereof, then provided Executive
executes and does not revoke a Release in accordance with Section 3.7, Executive shall be entitled to the following,
which payments and benefits shall be paid in accordance with this Section 3.2.3 and Section 3.7:

  continuing  payments  of  Executive’s  then-current  salary  for  the  Severance
Period  payable  subject  to  standard  federal  and  state  payroll  withholding  requirements  in  accordance  with
Employer’s regular payroll practices on Employer’s normal payroll schedule over the Severance Period, subject to
Section 3.7;  

(i)

(ii)

 Employer shall pay to Executive a lump sum payment equal to the gross sum
of  any  bonuses  or  portion  thereof  for  any  preceding  year  or  for  the  year  of  termination  which  bonus  has  been
approved  by  Employer,  but  has  not  been  received  by  Executive  prior  to  the  effective  date  of  termination,  less
applicable deductions and withholdings paid in accordance with Section 2.2 but in no event later than two and one-
half (2 1/2) months following the end of the fiscal year to which it relates. For the avoidance of doubt, (x) Executive
does not have to be employed by Employer on the date such bonuses are approved by the Employer to receive such
bonuses; and (y) this provision shall not be construed as guaranteeing the payment of a bonus for such year(s); and

 So long as Executive is eligible, and so long as Executive remains eligible,
for  and  upon  his  timely  election  of  COBRA  coverage,  Employer  will  continue  to  pay,  directly  to  the  healthcare
provider when due, 100% of the medical, vision and dental

(iii)

8

 
 
coverage premiums (including employee contributions, if any) until the earlier of (i) the end of the five (5) month
period following the effective date of termination; or (ii) the date when Executive becomes eligible for substantially
equivalent  health  insurance  coverage  in  connection  with  new  employment  (the  “Nonrenewal  COBRA  Payment
Period”); provided that Executive must immediately notify Employer in the event Executive becomes eligible for
coverage  under  another  employer’s  group  health  plan  during  the  Nonrenewal  COBRA  Payment  Period;  and
provided  further  that,  if  at  any  time  Employer  determines,  in  its  sole  discretion,  that  the  payment  of  the  COBRA
premiums would result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Code or any statute
or regulation of similar effect (including but not limited to the 2010 Patient Protection and Affordable Care Act, as
amended  by  the  2010  Health  Care  and  Education  Reconciliation  Act),  then  in  lieu  of  providing  the  COBRA
premiums for the remainder of the Nonrenewal COBRA Payment Period, Employer will instead pay Executive on
the  first  day  of  each  month  of  the  remainder  of  the  Nonrenewal  COBRA  Payment  Period,  a  fully  taxable  cash
payment equal to the COBRA premiums for that month, subject to applicable tax withholdings, for the remainder of
the Nonrenewal COBRA Payment Period.

3.3

 Nature of Payments. All amounts to be paid by Employer to Executive pursuant to Sections 3.2.1(i)
–  (iv)  and  3.2.3(i)  –  (iii)  are  considered  by  the  parties  to  be  severance  payments  and  are  in  lieu  of,  and  not  in
addition to, any benefits to which Executive may otherwise be entitled under any Employer severance plan, policy
or program.

3.4

 Duties Upon Termination.  During the Severance Period,  if there is a Severance Period applicable
to  Executive’s  termination  of  employment  from  Employer,  Executive  shall  fully  cooperate  with  Employer  in  all
matters relating to the winding up of Executive’s pending work including, but not limited to, any litigation in which
Employer  is  involved,  and  the  orderly  transfer  of  any  such  pending  work  to  such  other  employees  as  may  be
designated  by  Employer.    Notwithstanding  the  foregoing,  such  cooperation  requirement  shall  not  unreasonably
interfere with his then current employment or business activities.  With Employer’s prior approval, Executive shall
be reimbursed for all expenses reasonably incurred in connection with such cooperation.  Following the end of the
Severance  Period,  Executive  will  be  released  from  any  duties  and  obligations  hereunder  (except  those  duties  and
obligations  set  forth  in  Article  4  hereof).    In  the  event  of  termination  of  Executive’s  employment  pursuant  to
Sections  3.1.1  through  3.1.7  hereof,  the  obligations  of  Employer  to  Executive  will  be  as  set  forth  in  Section  3.2
hereof.

3.5

 Severance Period.    “Severance  Period”  shall  mean  a  period  of  nine  (9)  months  beginning  on  and

immediately following the effective date of Executive’s termination of employment with Employer.

3.6

 Release. Notwithstanding any provision of this Employment Agreement to the contrary, in no event
shall the timing of Executive’s execution of the Release, directly or indirectly, result in Executive designating the
calendar year of payment, and if a payment that is subject to the requirements of Section 409A of the Code and is
subject  to  execution  of  the  Release  could  be  made  in  more  than  one  taxable  year  based  on  when  the  Release  is
executed or becomes effective, payment shall be made in the later year.

3.7

  Commencement  of  Severance  Payments.    The  severance  payments  and  benefits    set  forth  in
Sections  3.2.1(i)  –  (iv)  (Termination  by  Employer  for  Death,  Disability,  Without  Cause,  by  Executive  for  Good
Reason)  and  Sections  3.2.3(i)  –  (iii)  (Termination  Upon  Non-Renewal  by  Employer)  above  will  not  be  paid  or
provided unless Executive executes and does not revoke the Release and the Release is enforceable and effective as
provided in the Release on or before the date that is the sixtieth (60 ) day following the effective date of termination
(such 60  day, the “Severance Pay Commencement Date”).  No cash severance payments will be paid pursuant to
Sections 3.2.1 or 3.2.3 prior to the Severance Pay Commencement Date.  On the Severance Pay Commencement
Date Employer will pay in a lump sum the aggregate amount of the cash severance payments that Employer would
have paid Executive through such date had the payments commenced on the effective date of termination through
the  Severance  Pay  Commencement  Date,  with  the  balance  paid  thereafter  on  the  applicable  schedules  described
above.  Notwithstanding  any  other  provision  of  this  Agreement  to  the  contrary,  it  is  intended  that  the  payment  of
severance upon termination for Good Reason by Executive in accordance with Section 3.1.7 satisfy the safe harbor
set  forth  in  Treasury  Regulation  Section  1.409A-1(n)(2)(ii)),  and  any  severance  payment  made  pursuant  to  this
Agreement shall satisfy the exemptions from the application of Section 409A of the Code provided under Treasury
Regulation Sections 1.409A‑1(b)(4), and 1.409A‑1(b)(9).

5.7

 Headings. The headings contained herein are for the sole purpose of convenience of reference, and

Employment Agreement.

5.8

 Binding Effect; Successors and Assigns. Executive may not delegate his duties or assign his rights
hereunder.  This  Employment  Agreement  will  inure  to  the  benefit  of,  and  be  binding  upon,  the  parties  hereto  and

executed  by  the  party  against  whom  or  which  enforcement  of  such  waiver  is  sought,  and  no  waiver  of  any  such
breach shall be construed or deemed to be a waiver of any other or subsequent breach.

5.10

 Continuing Effect.  Provisions of this Agreement which by their terms must survive the termination
of  this  Agreement  in  order  to  effectuate  the  intent  of  the  parties  will  survive  any  such  termination,  whether  by
expiration of the term, termination of Executive’s employment, or otherwise, for such period as may be appropriate
under the circumstances.

5.11

  Representations  and  Warranties  of  Executive.  Executive  hereby  represents  and  warrants  to
Employer that to the knowledge of Executive, Executive is not bound by any non-competition or other agreement
which would prevent his performance hereunder.

5.12

 Section 409A of the Code. This Employment Agreement is intended to comply with Section 409A
of  the  Code  and  its  corresponding  regulations,  or  an  exemption,  and  payments  may  only  be  made  under  this
Employment  Agreement  upon  an  event  and  in  a  manner  permitted  by  Section  409A  of  the  Code,  to  the  extent
applicable. Payment under this Employment Agreement is intended to be exempt from Code Section 409A under
the “short-teen deferral” exception set forth in Treasury Regulation Section 1.409A-1(b)(4), to the maximum extent
applicable, and then under the “separation pay” exception set forth in Treasury Regulation Section 1.409A-1(b)(9),
to  the  maximum  extent  applicable.  All  payments  to  be  made  upon  a  termination  of  employment  under  this
Agreement may only be made upon a “separation from service” within the meaning of Treasury Regulation Section
1.409A-1(h) (or any successor provision) (a “Separation from Service”). For purposes of Code Section 409A, the
right  to  a  series  of  installment  payments  under  this  Agreement  shall  be  treated  as  a  right  to  a  series  of  separate
payments.  In  no  event  may  the  Executive,  directly  or  indirectly,  designate  the  calendar  year  of  a  payment.  If  the
termination of employment giving rise to the payments described in Section 3.2.1 is not a Separation from Service,
then the amounts otherwise payable pursuant to

12

 
 
Section  3.2.1  will  instead  be  deferred  without  interest  and  paid  when  Executive  experiences  a  Separation  from
Service. Notwithstanding anything in this Employment Agreement to the contrary or otherwise, with respect to any
expense,  reimbursement  or  in-kind  benefit  provided  pursuant  to  this  Employment  Agreement  that  constitutes  a
“deferral of compensation” within the meaning of Section 409A of the Code and its implementing regulations and
guidance, (a) the expenses  eligible for  reimbursement or  in-kind  benefits provided to Executive must be incurred
during the Employment Term (or applicable survival period), (b) the amount of expenses eligible for reimbursement
or in-kind benefits provided to Executive during any calendar year will not affect the amount of expenses eligible
for reimbursement or in-kind benefits provided to Executive in any other calendar year, (c) the reimbursements for
expenses for which Executive is entitled to be reimbursed shall be made on or before the last day of the calendar
year  following  the  calendar  year  in  which  the  applicable  expense  is  incurred  and  (d)  the  right  to  payment  or
reimbursement  or  in-kind  benefits  hereunder  may  not  be  liquidated  or  exchanged  for  any  other  benefit.
 Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed by Employer at the time
of his Separation from Service to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code,
and  if  any  of  the  payments  due  upon  Separation  From  Service  set  forth  herein  and/or  under  any  other  agreement
with Employer are deemed to be “deferred compensation,” then to the extent delayed commencement of any portion
of such payments is required to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code and the
related adverse taxation under Section 409A of the Code, such payments will not be provided to Executive prior to
the earliest of (i) the expiration of the six (6)-month period measured from the date of Executive’s Separation From
Service with Employer, (ii) the date of Executive’s death or (iii) such earlier date as permitted under Section 409A
of the Code without the imposition of adverse taxation.  Upon the first business day following the expiration of such
applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph will be paid in a
lump sum to Executive, and any remaining payments due will be paid as otherwise provided in this Agreement or in
the applicable agreement.  No interest will be due on any amounts so deferred.

5.13

 Dispute Resolution.    The parties recognize that litigation in federal or state courts or before federal
or state administrative agencies of disputes arising out of the Executive’s employment with the Employer or out of
this Agreement, or the Executive’s termination of employment or termination of this Agreement, may not be in the
best interests of either the Executive or Employer, and may result in unnecessary costs, delays, complexities, and
uncertainty.    The  parties  agree  that  any  dispute  between  the  parties  arising  out  of  or  relating  to  the  negotiation,
execution, performance or termination of this Agreement or the Executive’s  employment, including, but not limited
to, any claim arising out of this Agreement, claims under Title VII of the Civil Rights Act of 1964, as amended, the
Civil Rights Act of 1991, the Age Discrimination in Employment Act of 1967, the Americans with Disabilities Act
of 1990, Section 1981 of the Civil Rights Act of 1966, as amended, the Family Medical Leave Act, the Executive
Retirement Income Security Act, and any similar federal, state or local law, statute, regulation, or any common law
doctrine,  whether  that  dispute  arises  during  or  after  employment,  shall  be  settled  by  binding  arbitration  in
accordance  with  the  National  Rules  for  the  Resolution  of  Employment  Disputes  of  the  American  Arbitration
Association;  provided  however,  that  this  dispute  resolution  provision  shall  not  apply  to  any  separate  agreements
between  the  parties  that  do  not  themselves  specify  arbitration  as  an  exclusive  remedy.  The  location  for  the
arbitration shall be the Philadelphia, Pennsylvania metropolitan area.  Any award made by such panel shall

be  final,  binding  and  conclusive  on  the  parties  for  all  purposes,  and  judgment  upon  the  award  rendered  by  the
arbitrators  may  be  entered  in  any  court  having  jurisdiction  thereof.  The  arbitrators’  fees  and  expenses  and  all
administrative fees and expenses associated with the filing of the arbitration shall be borne by Employer. The parties
acknowledge  and  agree  that  their  obligations  to  arbitrate  under  this  Section  survive  the  termination  of  this
Agreement  and  continue  after  the  termination  of  the  employment  relationship  between  Executive  and  Employer.
The  parties  each  further  agree  that  the  arbitration  provisions  of  this  Agreement  shall  provide  each  party  with  its
exclusive  remedy,  and  each  party  expressly  waives  any  right  it  might  have  to  seek  redress  in  any  other  forum,
except as otherwise expressly provided in this Agreement.  By election arbitration as the means for final settlement
of all claims, the parties hereby waive their respective rights to, and agree not to, sue each other in any action
in a Federal, State or local court with respect to such claims, but may seek to enforce in court an arbitration
award rendered pursuant to this Agreement.  The parties specifically agree to waive their respective rights to
a trial by jury, and further agree that no demand, request or motion will be made for trial by jury
