FORWARD-LOOKING STATEMENTS

This Annual  Report  on  Form  10-K  (“Annual  Report”)  contains  forward-looking  statements  that  involve  substantial  risks  and  uncertainties  for  purposes  of  the  safe  harbor
provided by the Private Securities Litigation Reform Act of 1995. All statements contained in this Annual Report other than statements of historical fact, including statements
relating  to  future  financial,  business,  and/or  research  and  clinical  performance,  conditions,  plans,  prospects,  trends,  or  strategies  and  other  such  matters,  including  without
limitation,  our  strategy,  future  operations,  future  financial  position,  future  liquidity,  future  revenue,  projected  expenses,  results  of  operations,  the  anticipated  timing,  scope,
design,  progress,  results  and/or  reporting  of  data  of  ongoing  and  future  non-clinical  studies  and  clinical  trials,  intellectual  property  rights,  including  the  validity,  term,  and
enforceability of such, the expected timing and/or results of regulatory submissions and approvals, and prospects for commercializing any of Brickell’s product candidates, or
research  collaborations  with,  or  actions  of,  its  partners,  including  in  Japan,  the  United  States  (“U.S.”)  or  any  other  country.  The  words  “believe,”  “may,”  “could,”  “will,”
“estimate,”  “continue,”  “anticipate,”  “intend,”  “plan,”  “expect,”  “predict,”  “potential,”  “opportunity,”  “goals,”  “looking  forward”  or  “should,”  and  similar  expressions  are
intended  to  identify  forward-looking  statements.  Such  statements  are  based  on  management’s  current  expectations  and  involve  risks  and  uncertainties. Actual  results  and
performance  could  differ  materially  from  those  projected  in  the  forward-looking  statements  as  a  result  of  many  factors.  Unless  otherwise  mentioned  or  unless  the  context
requires otherwise, all references in this Annual Report to “Brickell,” “Brickell Subsidiary,” “Company,” “we,” “us,” and “our,” or similar references, refer to Brickell Biotech,
Inc., and our consolidated subsidiaries.

We  based  these  forward-looking  statements  largely  on  our  current  expectations  and  projections  about  future  events  and  trends  that  we  believe  may  affect  our  financial
condition,  results  of  operations,  business  strategy,  short-term  and  long-term  business  operations  and  objectives,  and  financial  needs.  These  forward-looking  statements  are
subject to a number of risks, uncertainties, and assumptions, including those described in Part I, Item 1A, “Risk Factors” in this Annual Report, and under a similar heading in
any other periodic or current report we may file with the U.S. Securities and Exchange Commission (the “SEC”) in the future. Moreover, we operate in a very competitive and
rapidly changing environment. New risks emerge quickly and from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all
factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking
statements we may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this Annual Report may not occur and actual results
could differ materially and adversely from those anticipated or implied in the forward-looking statements. We undertake no obligation to revise or publicly release the results of
any  revision  to  these  forward-looking  statements,  except  as  required  by  law.  Given  these  risks  and  uncertainties,  readers  are  cautioned  not  to  place  undue  reliance  on  such
forward-looking statements. All forward-looking statements are qualified in their entirety by this cautionary statement.

You should read carefully the factors described in Part I, Item 1A, “Risk Factors” in this Annual Report to better understand the risks and uncertainties inherent in our business
and underlying any forward-looking statements. You are advised to consult any further disclosures we make on related subjects in our future public filings and on our website.

Our business, financial condition, and operating results may be affected by a number of factors, whether currently known or unknown. Any one or more of such factors could
directly or indirectly cause our actual results of operations and financial condition to vary materially from past or anticipated future results of operations and financial condition.
Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition, results of operations, and stock price. We have provided a
summary of some of these risks below, with a more detailed explanation of those and other risks applicable to the Company in Part I, Item 1A. “Risk Factors” in this Annual
Report.

RISK FACTORS SUMMARY

•

Our business depends on the successful financing, clinical development, regulatory approval, and commercialization of sofpironium bromide.

• We have never conducted a pivotal Phase 3 clinical trial ourselves and may be unable to successfully do so for sofpironium bromide.

•

•

•

•

•

•

•

Clinical drug development for sofpironium bromide is expensive, time-consuming, and uncertain.

Use  of  patient-reported  outcome  (“PRO”)  assessments  and  gravimetric  assessments  in  sofpironium  bromide  clinical  trials  may  delay  or  adversely  impact  the
development of sofpironium bromide gel or clinical trial results or increase our development costs.

Sofpironium bromide may cause undesirable side effects or have other unexpected properties that could delay or prevent its regulatory approval, limit the commercial
profile of an approved label, or result in post-approval regulatory action.

Kaken Pharmaceutical Co., Ltd., (“Kaken”), substantially controls the development of sofpironium bromide in Japan and certain other Asian countries and may make
decisions  regarding  product  development,  regulatory  strategy,  and  commercialization  that  may  not  be  in  our  best  interests.  Kaken  may  be  unable  to  secure  an
appropriate local business partner (if desirable) and/or obtain approval of the drug in the ex-Japan Asian markets, over which it has rights.

If  we  or  any  partners  with  which  we  may  collaborate  to  market  and  sell  sofpironium  bromide  are  unable  to  achieve  and  maintain  medical  insurance  coverage  and
adequate levels of reimbursement for this compound following regulatory approval and usage by patients, our commercial success may be hindered severely.

Even if sofpironium bromide obtains regulatory approval, and despite our partner Kaken launching the drug as ECCLOCK  in Japan in 2020, it may fail to achieve the
broad degree of physician and patient adoption and use necessary for commercial success.

®

Sofpironium bromide, if approved, will face significant competition and its failure to compete effectively may prevent it from achieving significant market penetration.

• We may face generic competition for sofpironium bromide, which could expose us to litigation or adversely affect our business, financial condition, operating results,

and prospects.

•

•

If third-party Clinical Research Organizations (“CROs”) and other third parties do not meet our requirements or otherwise conduct our sofpironium bromide clinical
trials as required or are unable to staff our trials, or do not effectively and timely enroll patients in these trials, particularly the ongoing U.S. registration trials, we may
not be able to satisfy our contractual obligations or obtain regulatory approval for, or commercialize, sofpironium bromide at all or in the time frames currently planned
for.

If we are unable to establish sales and marketing capabilities on our own or through third parties, or are delayed in establishing these capabilities, we will be unable to
successfully commercialize our product candidates, if approved, or generate product revenue.

• We will need to raise substantial additional financing in the future to fund our operations and/or prepare a new drug application (“NDA”) submission in the U.S. for

sofpironium bromide, which may not be available to us on favorable terms or at all.

•

If the holders of our company’s stock options and warrants exercise their rights to purchase our common stock, the ownership of our stockholders will be diluted.

5

Table of Contents

• We may never obtain regulatory approval to commercialize any of our product candidates in the U.S., or anywhere else in the world other than Japan, and any products
approved for sale will be subject to continued regulatory review and compliance obligations and there could be further restrictions on post-approval activities, including
commercialization efforts. In obtaining regulatory approval, we will need to negotiate an appropriate product label (aka package insert) with the regulators, which will
determine  the  extent  of  our  allowed  promotional  activities,  and  this  label  could  be  restrictive  or  prohibitory  with  regard  to  subject  matter  we  believe  is  necessary  to
maximize the commercial success of sofpironium bromide.

• Major public health issues, and specifically the pandemic caused by the spread of novel Coronavirus (“COVID-19”) and COVID-19 variants that are recently emerging,
could have an adverse impact on our financial condition and results of operations and other aspects of our business and that of our suppliers, contractors, and business
partners.

• We have sponsored or supported and may in the future sponsor or support clinical trials for our product candidates outside the U.S. and Japan, and the Food and Drug
Administration (“FDA”), Japan’s Pharmaceuticals and Medical Devices Agency (“PMDA”), and applicable foreign regulatory authorities may not accept data from such
trials; in addition, we may not be allowed alone or with local country business partners to obtain regulatory approval for our product candidates without first conducting
clinical trials in each of these other countries.

• We may face product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is

inadequate.

• We may be subject to risks related to pre-approval promotion or off-label use, or unauthorized direct-to-consumer advertising, of our product candidates.

•

Healthcare reform measures, including price controls or restricted access, could hinder or prevent the commercial success of our product candidates.

• We also may be subject to stricter healthcare laws, regulation, and enforcement, and our failure to comply with those laws could expose us to liability or adversely affect

our business, financial condition, operating results, and prospects.

• We  rely  completely  on  third-party  contractors  to  supply,  manufacture,  and  distribute  clinical  drug  supplies  for  our  product  candidates,  including  certain  sole-source
suppliers and manufacturers; we intend to rely on third parties for commercial supply, manufacturing, and distribution if any of our product candidates receive regulatory
approval;  and  we  expect  to  rely  on  third  parties  for  supply,  manufacturing,  and  distribution  of  preclinical,  clinical,  and  commercial  supplies  of  any  future  product
candidates.

• Manufacturing and supply of the active pharmaceutical ingredients (“API”) and other substances and materials used in our product candidates and finished drug products
is a complex and technically challenging undertaking, and there is potential for failure at many points in the manufacturing, testing, quality control and assurance, and
distribution supply chain, as well as the potential for latent defects after products have been manufactured and distributed.

• We may not be able to finance or acquire additional pipeline or marketed assets to grow or sustain our company business.

• We may not be able to obtain, maintain, or enforce global patent rights or other intellectual property rights that cover sofpironium bromide and related technologies (and

any other product candidates) that are of sufficient breadth and term.

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

•

If we fail to comply with our obligations under our intellectual property license agreements, we could lose license rights that are important to our business. Additionally,
these  agreements  may  be  subject  to  disagreement  over  contract  interpretation,  which  could  narrow  the  scope  of  our  rights  to  the  relevant  intellectual  property  or
technology or increase our financial or other obligations to our licensors.

PART I.

ITEM 1. BUSINESS

Overview

We are a clinical-stage pharmaceutical company focused on the development of innovative and differentiated prescription therapeutics for debilitating skin diseases with a focus
on  our  lead  asset  for  the  treatment  of  hyperhidrosis.  Our  executive  management  team  and  board  of  directors  bring  extensive  experience  in  product  development  and  global
commercialization, having served in leadership roles at large global pharmaceutical companies and biotechs that have developed and/or launched successful products, including
®
several that were first-in-class and/or achieved iconic status, such as Cialis , Taltz , Gemzar , Prozac , Cymbalta , and Juvederm .

®

®

®

®

Our  pivotal  Phase  3  clinical-stage  investigational  product  candidate,  sofpironium  bromide,  is  a  new  chemical  entity  that  belongs  to  a  class  of  medications  called
anticholinergics. Anticholinergics  block  the  action  of  acetylcholine,  a  chemical  that  transmits  signals  within  the  nervous  system  that  are  responsible  for  a  range  of  bodily
functions, including activation of the sweat glands. Sofpironium bromide was retrometabolically designed. Retrometabolic drugs are designed to exert their action locally and
are potentially rapidly metabolized to a less active form once absorbed into the blood. This proposed mechanism of action may allow for potentially highly effective doses to be
used while limiting systemic side effects. We intend to develop sofpironium bromide as a potential best-in-class, self-administered, once daily, topical therapy for the treatment
of primary axillary (underarm) hyperhidrosis.

Hyperhidrosis is a life-altering condition of sweating beyond what is physiologically necessary for thermoregulation of the body. It is believed to be caused by an overactive
cholinergic response of the sweat glands and affects an estimated 15.3 million, or 4.8%, of the U.S. population. According to a 2016 update on the prevalence and severity of
hyperhidrosis in the U.S. by Doolittle et al., axillary hyperhidrosis, which is the targeted first potential indication for sofpironium bromide, is the most common occurrence of
hyperhidrosis, affecting approximately 65% of patients, or an estimated 10 million individuals, in the U.S.

We are currently developing sofpironium bromide in the U.S. for the treatment of primary axillary hyperhidrosis. In the fourth quarter of 2020, we initiated the pivotal Phase 3
program for sofpironium bromide, which is comprised of two pivotal Phase 3 clinical trials (Cardigan I and II) to evaluate the safety and efficacy of sofpironium bromide gel,
15% compared to vehicle (placebo) in approximately 350 subjects (per trial) aged nine years or older with primary axillary hyperhidrosis in the U.S. We expect to report topline
results from the pivotal Phase 3 program in the fourth quarter of 2021. If successful, the results from these studies are expected to form the basis of a prospective NDA in the
U.S. with the FDA for the treatment of primary axillary hyperhidrosis.

Collaboration with Kaken in Asia

We and our development partner in Asia, Kaken, have conducted multiple clinical trials of sofpironium bromide gel that encompass over 1,300 subjects in the U.S. and Japan.
These trials evaluated the potential safety, tolerability, pharmacokinetics (“PK”), and efficacy of sofpironium bromide gel in adult and pediatric patients with primary axillary
hyperhidrosis  and  healthy  adult  subjects.  Under  our  License,  Development  and  Commercialization Agreement  with  Kaken,  dated  March  31,  2015  (as  amended,  the  “Kaken
Agreement”), in exchange for paying us an upfront, non-refundable payment, we granted Kaken the exclusive right to develop, manufacture, and commercialize sofpironium
bromide in Japan and certain other Asian countries.

In  September  2020,  Kaken  received  regulatory  approval  in  Japan  to  manufacture  and  market  sofpironium  bromide  gel,  5%  (brand  name:  ECCLOCK )  for  the  once-daily
treatment of primary axillary hyperhidrosis. Japan is the first country to approve sofpironium bromide, which also marks the first approval of a topical prescription product for
the treatment of primary axillary hyperhidrosis in Japan. This approval was based on the results of Kaken’s Japanese pivotal Phase 3 registration study of sofpironium bromide
gel, 5% in 281 patients with primary axillary hyperhidrosis, in which all primary and secondary efficacy endpoints demonstrated statistically significant differences between
sofpironium  bromide  gel  and  vehicle.  In  addition,  sofpironium  bromide  gel,  5%  was  observed  to  be  safe  and  generally  well  tolerated  in  this  study,  as  well  as  in  the
accompanying 52-week long-term safety extension study with 185 patients in Japan.

Table of Contents

After receiving regulatory approval in 2020 for ECCLOCK  from Japanese regulators, Kaken applied for and received pricing approval in Japan, which is required by law to do
so  before  selling.  In  November  2020,  ECCLOCK   was  placed  on  Japan’s  National  Health  Insurance  (“NHI”)  drug  reimbursement  price  list.  The  NHI  listed  drug  price  for
ECCLOCK  in Japan is ¥243.70 per gram, which is ¥4,874.00 (USD $46.47) for a 20-gram bottle or approximately a two-week supply.

®

®

®

In November 2020, Kaken launched commercial sales of ECCLOCK  in Japan. Under the Kaken Agreement, we are entitled to receive commercial milestone payments, as
well  as  tiered  royalties  based  on  a  percentage  of  net  sales  of  sofpironium  bromide  gel  in  Japan.  Furthermore,  Kaken  has  rights  to  develop  and  commercialize  sofpironium
bromide in South Korea, China, and certain other Asian countries, and we are entitled to receive royalties based on a percentage of Kaken’s net sales in these countries. At this
time, Kaken is focused only on commercialization of the sofpironium bromide gel in Japan. In the fourth quarter of 2020, we began recognizing royalty revenue earned on a
percentage of net sales of sofpironium bromide in Japan.

®

Our Strategy

Our  strategy  is  to  identify,  develop,  and  commercialize  innovative  and  differentiated  pharmaceutical  products  that  we  believe  can  be  successful  in  the  marketplace  and
transform lives by solving currently unmet patient needs. The key components of our patient-focused strategy are to:

Advance our lead late-stage product candidate, sofpironium bromide, through pivotal U.S. Phase 3 clinical trials and engage appropriately with patients and members of
the  dermatology  community. We  believe  that  our  management  team’s  expertise  in  designing  and  executing  product  development  programs  in  dermatology  and  other
therapeutic areas, will enable us to advance sofpironium bromide through pivotal Phase 3 clinical trials in the U.S. If approved, we intend to promote awareness of sofpironium
bromide  and  hyperhidrosis  among  key  opinion  leaders,  including  prescribing  dermatologists  and  pediatricians,  patient  advocacy  groups  like  the  International  Hyperhidrosis
Society, and directly to patients and their families coping with primary axillary hyperhidrosis. Consumer activation through a variety of media, including social media, will be
essential to educate both patients and physicians appropriately regarding hyperhidrosis and the potential benefits associated with a safe, effective, and differentiated treatment
option for this debilitating condition.

Evaluate our existing early-stage product candidates, in-license or acquire new product candidates and, potentially, commercial-stage products, while maintaining a strong
relationship  with  our  current  strategic  partner.  We intend to continue to evaluate our existing pipeline of product candidates and will also explore other potential external
product opportunities. We intend to continue to identify, evaluate, in-license and acquire attractive product candidates at the appropriate level of investment from a variety of
strategic sources. We entered into an out-license transaction with Kaken for the development and commercialization of sofpironium bromide in Japan and certain other Asian
countries. We expect to continue to engage with Kaken and further develop our strong global partnership to create value for sofpironium bromide in the U.S., Japan, and other
countries.

Expand  our  team  of  enthusiastic,  committed,  and  experienced  professionals. We  intend  to  expand  our  team  by  selectively  identifying  and  hiring  experienced,  talented,
dedicated, and diverse employees who align with our culture, values, and patient-centric mission and can make significant contributions to our company, consistent with our
current (and any future) financing.

Hyperhidrosis

Hyperhidrosis is a debilitating, life-altering skin disorder of chronic excessive sweating beyond what is physiologically necessary for thermoregulation of the body. Current
estimates show that primary axillary hyperhidrosis (excessive underarm sweating without an alternative origin) affects approximately 4.8% of the U.S. population, or over 15
million people, and about 8.8% and 17.1% of the U.S. population ages 18 to 39 and 12 to 17, respectively. Of hyperhidrosis sufferers, 70% report severe excessive sweating that
they cannot control or shut off in at least one body area. The most common area where excessive sweating occurs is the underarms (axilla; 51%), followed by the face (42%),
palms  of  the  hands  (40%),  and  the  soles  of  the  feet  (38%).  It  is  estimated  that  nearly  half  (49%)  of  people  with  hyperhidrosis  have  not  discussed  their  condition  with  a
healthcare professional, either because they do not yet know it is a medical condition or believe that no adequate treatment options exist. Furthermore, in one survey, 75% of
subjects with hyperhidrosis said that it has had negative impacts on their professional and social lives, sense of well-being, and emotional and mental health. We believe that,
due  to  the  lack  of  diagnosis,  available  treatment  options,  and  knowledge  about  the  disease,  hyperhidrosis  presents  a  substantial  market  opportunity  for  a  new,  innovative,
effective, and well-tolerated topical treatment. We believe that such a therapy could not

8

Table of Contents

only penetrate the segment of patients who currently seek treatment from a physician, but also encourage more patients to come forward and seek treatment for this condition
that causes them to deal with (and try to hide) it each and every day.

Current Hyperhidrosis Treatment Options and Limitations

The market for products to control sweating is large yet highly underpenetrated by innovative prescription pharmaceutical products thoroughly tested in clinical trials. More
specifically, current hyperhidrosis treatment options generally fall into one of the following categories:

•

•

•

Self-administered topicals, which include topical antiperspirants, some of which are prescription only, containing metal salts like aluminum that block the release of
sweat to the skin surface by clogging the opening of the duct and Qbrexza  (glycopyrronium) cloth, approved in June 2018 by the FDA for the topical treatment of
primary axillary hyperhidrosis in adult and pediatric patients nine years of age and older. For decades, topical antiperspirants containing metal salts have been the most
widely used treatment option for hyperhidrosis. Over-the-counter (“OTC”) antiperspirants contain low concentrations of metal salts and are generally well-tolerated but
limited  in  efficacy.  Prescription  antiperspirants  containing  higher  concentrations  of  metal  salts  are  typically  recommended  as  the  treatment  of  choice  when  OTC
antiperspirants prove ineffective. However, these are only marginally more effective, and their tolerability is limited by skin irritation associated with increased metal salt
concentrations,  which  react  with  water  to  form  irritating  hydrochloric  acid  on  the  skin.  Qbrexza  is  available  by  prescription  and  is  administered  once  nightly  by  the
patient using a single-use cloth pre-moistened with the active ingredient, 2.4% glycopyrronium solution, packaged in individual pouches. Qbrexza inhibits the action of
acetylcholine on sweat glands, thereby reducing sweating. While Qbrexza is approved in the U.S. for the treatment of primary axillary hyperhidrosis, we believe that
there is room to expand the market in general with disease and treatment education and for additional products with improved efficacy and/or tolerability profiles.

®

Injectable,  systemic,  and  other  treatments that  block  activation  of  the  sweat  glands.  Therapeutic  options  for  patients  who  are  not  satisfied  with  topical  therapies  are
largely limited to more cumbersome or invasive treatment strategies directed either to blocking the activation of, destroying, or removing altogether the sweat glands.
Intradermal injections of botulinum toxin type A, or BOTOX , a neurotoxin that blocks the release of acetylcholine, are effective but can be painful, costly, and must be
administered by a physician with patients receiving on average 20 to 40 injections to each axilla every six to nine months. A microwave device, MiraDry , is designed to
overheat and destroy sweat glands as a different option. However, treatment with MiraDry may be painful, require multiple physician visits, cause permanent destruction
of the sweat glands, and is not generally covered by insurance. All these treatments are time-consuming and require a significant investment of physician training and
administration time and, in the case of microwave treatment, capital investment by the treating physician. As a result, these treatments have limited attractiveness both to
doctors and their patients. Furthermore, they are also not approved or well-suited for application to other affected body areas, including the hands or feet. Iontophoresis,
which  involves  soaking  the  hands  or  feet  in  water  through  which  an  electrical  current  is  passed,  can  be  performed  in  a  physician’s  office  or  at  home,  but  requires
repeated, time-consuming, and often bothersome treatments.

Surgical and other procedures intended to destroy or remove sweat glands. Some patients with severe hyperhidrosis may choose to be treated with invasive surgical
techniques  that  involve  removal  of  sweat  glands  or  destruction  of  nerves  that  transmit  activating  signals  to  the  glands.  Surgery  is  a  significant  and  costly  permanent
undertaking that can be associated with numerous severe side effects, including increased compensatory sweat production in other body areas.

Deciding among these available treatments depends on many factors including price, ease of administration, the applicable treatment’s safety, efficacy and tolerability profile,
the affected area, severity of the disease and impact on the patient’s quality of life due to the disease being uncontrolled. As a result of the limitations of the currently available
treatment options, we believe that there is a significant unmet patient need for a new, effective, safe, well-tolerated, self-administered, prescription topical hyperhidrosis therapy.

Sofpironium Bromide for Primary Axillary Hyperhidrosis

Sofpironium bromide, our lead investigational product candidate, is a new chemical entity that belongs to a class of medications called anticholinergics. We intend to develop
sofpironium bromide as a potential best-in-class, self-administered, once daily, topical therapy for the treatment of primary axillary hyperhidrosis in adult and pediatric patients
nine years of age

and older. Sofpironium bromide was designed as a structural analog of a well-known potent anticholinergic, glycopyrrolate, to achieve its therapeutic effect at the application
site (skin) similar to glycopyrrolate. However, it differs from glycopyrrolate in that sofpironium bromide was retrometabolically designed. Retrometabolic drugs are intended to
exert their action locally and are potentially rapidly metabolized to a less active form once absorbed into the blood. This retrometabolic approach to drug design is intended to
allow for potentially highly effective doses to be used while limiting systemic side effects.

Key design attributes of a retrometabolic drug include:

•

•

•

The synthesis of a retrometabolic drug is achieved by starting with a known inactive metabolite of a known active drug (e.g., glycopyrrolate).

The  inactive,  or  less  active,  metabolite  is  then  structurally  modified  to  an  active  form  (an  analogue  of  active  drug  in  this  case,  glycopyrrolate)  that  will  undergo  a
predictable one-step transformation back into the inactive metabolite in vivo after exerting its therapeutic effect.

Thus, the retrometabolic drug concept is based upon predictable metabolic deactivation processes by both hydrolysis and further enzymatic (e.g., CYP450) metabolism,
predominantly following systemic absorption.

Sofpironium bromide is delivered as a gel formulation in a metered-dose pump with an applicator that allows patients to avoid unwanted direct product contact to the hands or
other non-axillary body parts. We believe that this will help avoid certain side effects that could be caused by the unintended transference of the drug, such as to the eyes.

Clinical Development of Sofpironium Bromide

We, and our development partner Kaken, have conducted multiple clinical trials of sofpironium bromide gel that encompass over 1,300 subjects in the U.S. and Japan. These
trials evaluated the potential safety, tolerability, PK, and efficacy of sofpironium bromide gel in adult and pediatric patients with primary axillary hyperhidrosis and healthy
adult subjects.

In clinical studies conducted to date, all three concentrations of sofpironium bromide gel tested (5%, 10%, and 15%) were safe and generally well tolerated. Treatment-emergent
adverse events (“TEAEs”) were mostly mild or moderate in severity. There has been one death unrelated to sofpironium bromide, and no serious adverse reactions have been
reported  in  any  clinical  studies  with  sofpironium  bromide  gel.  Thirteen  serious  adverse  events  (“SAEs”)  have  been  reported,  and  all  were  determined  to  be  unrelated  to
sofpironium bromide gel administration. Consistent with a retrometabolic drug design, a low incidence of systemic TEAEs has been found in all clinical studies of sofpironium
bromide gel with a trend toward dose-dependency observed. The most common TEAEs were dry mouth and blurred vision. Of note, the TEAEs were predominantly mild or
moderate in severity and transient in duration (i.e., resolving gradually with continued use). Local application site tolerability reactions of burning, itching, pain, erythema, and
dryness at the axillae were predominantly minimal in severity and typically transient.

Overall,  all  three  sofpironium  bromide  gel  concentrations,  5%,  10%,  and  15%,  exhibited  a  larger  absolute  mean  reduction  in  gravimetric  sweat  production  (“GSP”)  from
baseline to end of treatment (“EOT”) compared with vehicle, with the reduction at the 15% concentration being statistically significant. However, while there was a slight trend
toward  dose  response,  all  gel  concentrations  were  essentially  similar  in  patient-reported  outcome  (“PRO”)  measures  based  on  the  Hyperhidrosis  Disease  Severity  Measure-
Axillary  (“HDSM-Ax”),  modified  Dermatology  Life  Quality  Index  (“DLQI”),  and  Hyperhidrosis  Disease  Severity  Score  (“HDSS”).  All  three  sofpironium  bromide  gel
concentrations, 5%, 10%, and 15%, were statistically significant on the HDSM-Ax PRO assessment. Also, the HDSM-Ax responses were seen as early as Day 8 and remained
consistent throughout the applicable treatment period.

U.S. Phase 2b Clinical Trial (BBI-4000-CL-203)

The U.S. Phase 2b clinical trial was a multicenter, randomized, double blind, vehicle-controlled clinical trial to evaluate the safety and efficacy of topically applied sofpironium
bromide  gel,  5%,  10%,  and  15%,  in  patients  with  primary  axillary  hyperhidrosis.  The  trial  enrolled  a  total  of  227  patients  across  23  clinical  sites  in  the  U.S.,  with  patients
randomized to either sofpironium bromide gel, 5% (n=57), 10% (n=57), 15% (n=56), or vehicle gel (placebo; n=57) who applied the assigned product to the axillae (underarms)
once daily, at bedtime, for 42 days. The objectives of this trial were to evaluate (1) the effect of sofpironium bromide gel, 5%, 10%, and 15% on hyperhidrosis disease severity
as it relates to HDSM-Ax, GSP, HDSS, and modified DLQI; and (2) the safety and local tolerability of sofpironium bromide gel, 5%, 10%, and 15%.

Table of Contents

Changes  in  HDSM-Ax  measures  indicated  statistically  significant  differences  from  placebo  in  all  sofpironium  gel  dose  groups  with  all  methods  of  analysis.  Statistically
significant differences in favor of active treatment groups were observed as early as Day 8 and were sustained over time. A significant higher proportion of active treatment
subjects  had  at  least  a  2-point  change  from  baseline  to  EOT  in  HDSM-Ax-11  items  scale  (5%  gel:  47.4%,  p=0.007;  10%  gel:  49.1%,  p=0.006;  15%  gel:  50.0%,  p=0.002;
vehicle: 22.8%). Larger absolute mean reductions in GSP from baseline to EOT were found for all sofpironium bromide gel concentrations compared to vehicle gel, with the
results with sofpironium bromide gel, 15% being statistically significant. Treatment with sofpironium bromide gel, 15% (U.S. pivotal Phase 3 active dose group) resulted in
statistically significant reduction in GSP from baseline to EOT (-217 mg, p=0.06; vehicle: -143 mg). The 5% and 10% dose groups resulted in -163 mg (p=0.32) and -174 mg
(p=0.26)  reduction  in  GSP  from  baseline  to  EOT,  respectively.  Consistently,  superior  ranked  values  indicating  GSP  reduction  from  baseline  to  EOT  were  observed  for
sofpironium bromide gel, 15% in comparison to vehicle. The ranked order analysis did not indicate a baseline to EOT reduction in GSP for the vehicle group; a p-value of 0.04
comparing sofpironium bromide, 15% gel to vehicle indicated the sofpironium bromide, 15% improvement to be real and not observed by chance. All sofpironium bromide gel
groups met the secondary efficacy endpoints for HDSS and modified DLQI. It was prespecified in the study protocol and statistical analysis plan that as a Phase 2 study, a 1-
sided p<0.10 in favor of an active treatment would be regarded as statistically significant. All p-values cited in this study were 1-sided per the protocol and statistical analysis
plan.

Among the safety population (includes all subjects who received study drug at least once; n=225), the subject incidence of TEAEs was higher in the sofpironium bromide gel
15% group (51.9%) compared to the other groups (5% gel: 29.8%; 10% gel: 33.6%; vehicle gel: 15.8%). The majority of the systemic TEAEs were consistent with adverse
events due to anticholinergic activity. The most common TEAEs included dry mouth (5% gel: 15.8%; 10% gel: 17.5%; 15% gel: 22.2% and vehicle gel: 1.8%) and blurred
vision (5% gel: 3.5.%; 10% gel: 10.5%; 15% gel: 9.3% and vehicle gel: 0.0%). The majority of TEAEs in each group were mild or moderate in severity. Severe TEAEs were
reported by 4 subjects in the 15% group and 2 subjects each in the 10% and 5% groups. The vast majority of severe TEAEs were anticholinergic TEAEs (dry mouth and vision
blurred) or application site TEAEs (application site pain, application site pruritus, application site erythema, application site dryness, and application site exfoliation). There was
one  case  of  severe  osteomyelitis  that  was  an  SAE  assessed  as  not  related  to  sofpironium  bromide  gel.  Treatment  in  all  dose  groups  was  well-tolerated.  Local  tolerability
assessments  indicated  that  all  three  active  treatment  groups;  15%,  10%,  and  5%  were  well  tolerated  over  the  42-day  treatment  period.  Each  local  tolerability  symptom/sign
(burning, itching, dryness, scaling, and erythema) was absent in the majority of subjects in each group at each study visit. The incidence of these symptoms/signs was generally
higher in the sofpironium bromide gel groups compared to the vehicle group. The majority of tolerability symptoms/signs were minimal to mild in severity and most resolved by
the Day 57 visit. Severe tolerability symptoms/signs (burning, itching, and erythema) were reported only in the sofpironium bromide gel groups.

Our U.S. Pivotal Phase 3 Clinical Trials

Based on the positive results observed in clinical trials for sofpironium bromide conducted globally to date by us and Kaken, we initiated during the fourth quarter of 2020 two
U.S. pivotal Phase 3 clinical trials (also referred to as our “Phase 3 Program” or “Cardigan Studies”) that are both currently enrolling patients.

In October 2020, we initiated our first of two pivotal U.S. Phase 3 clinical studies evaluating sofpironium bromide gel, 15% for the treatment for primary axillary (underarm)
hyperhidrosis (the “Cardigan I Study”). The Cardigan I Study is expected to enroll up to 350 subjects aged nine years and older with primary axillary hyperhidrosis and is a
multicenter,  randomized,  double-blinded,  vehicle  (placebo)-controlled  Phase  3  study  to  evaluate  the  safety  and  efficacy  of  topically  applied  sofpironium  bromide  gel,  15%.
Subjects will apply sofpironium bromide or vehicle once daily at bedtime to their underarms for six consecutive weeks, with a two-week post-treatment follow-up. The co-
primary  efficacy  endpoints  of  the  Cardigan  I  Study  include  the  proportion  of  subjects  achieving  at  least  a  2-point  improvement  on  the  HDSM-Ax  scale,  a  proprietary  and
validated PRO measure, and change in GSP, each from baseline to EOT. In addition, safety and tolerability assessments will be performed throughout the study. As of the date
of filing of this Annual Report, we have exceeded 50% enrollment in the Cardigan I study.

In December 2020, we initiated the second of the two pivotal U.S. Phase 3 clinical trials for sofpironium bromide gel, 15% for the primary axillary (underarm) hyperhidrosis
(the “Cardigan II Study”). The Cardigan II Study will evaluate the safety and efficacy of sofpironium bromide gel, 15% versus vehicle in approximately 350 subjects aged nine
years and older with primary axillary hyperhidrosis. As of the date of filing of this Annual Report, all investigational sites are activated, and enrollment of subjects has begun.

Table of Contents

We expect to complete enrollment of the Cardigan Studies in the third quarter of 2021 and anticipate announcing topline results from the Cardigan Studies in the fourth quarter
of 2021. If successful, the results from the Cardigan Studies are expected to form the basis of a prospective NDA in the U.S. for sofpironium bromide gel, 15% for the treatment
of primary axillary hyperhidrosis.

U.S. Phase 3 Open-Label Long-Term Safety Study

In July 2020, we completed our 12-month Phase 3, open-label, long-term safety study evaluating sofpironium gel, 5% and 15% in 300 subjects aged nine years and older with
primary  axillary  hyperhidrosis.  The  study  results  confirmed  to  us  that  sofpironium  bromide  gel,  at  both  concentrations,  was  safe  and  generally  well  tolerated,  which  was
consistent with the earlier Phase 2 clinical trial results. No treatment-related SAEs were observed.

Japan Pivotal Phase 3 Clinical Trial

The Japan Phase 3 pivotal study was a randomized, double-blinded, vehicle-controlled study evaluating the safety and efficacy of topically applied sofpironium bromide gel,
5% in Japanese patients with primary axillary hyperhidrosis. The Phase 3 pivotal study evaluated a total of 281 Japanese subjects at 22 sites. Subjects were randomized 1:1 to
apply sofpironium bromide gel, 5% or vehicle gel (placebo) once daily to the axillae for 42 days. All subjects had HDSS scores ≥ 3, HDSM-Ax scores ≥ 2 and ≥ 50 mg/5 min
GSP in each axilla at baseline. All primary, secondary, and exploratory endpoints were met and demonstrated statistically significant differences between sofpironium bromide
gel and placebo. In addition, sofpironium bromide gel was deemed to be safe and generally well tolerated in this study.

Other Pipeline Programs

While  we  are  primarily  focused  on  the  development  of  sofpironium  bromide  gel  for  the  treatment  of  primary  axillary  hyperhidrosis,  we  will  continue  to  evaluate  the
development of our current earlier stage pipeline, as well as the potential to in-license and/or acquire other potential drug candidates.

AnGes Collaboration Agreement

In September 2020, we entered into a collaboration agreement with AnGes, Inc. (“AnGes”) relating to the development and potential commercialization of AnGes’ proprietary
investigational adjuvanted plasmid DNA vaccine intended to prevent COVID-19. Under the terms of the collaboration agreement, AnGes will continue to lead the development
of its vaccine candidate in Japan, and we will provide information and know-how that could be relevant to such development efforts. If AnGes obtains positive results from its
clinical studies in Japan and we are able to satisfy certain conditions, including raising the required development funding, we would have the right to lead the development
efforts in the U.S. and certain emerging markets. If ultimately approved for sale in the applicable jurisdictions, AnGes would have commercial rights to the vaccine in Japan and
we would have commercial rights in the U.S. and certain emerging markets on terms and conditions to be agreed with AnGes prior to any launch of a vaccine product. AnGes
completed a Phase 1/2 study and is currently conducting a Phase 2/3 clinical study with its vaccine candidate in Japan. If the development process continues based on this effort,
a larger Phase 3 registration study will be required for any regulatory approval.

Competition

Our industry is highly competitive and subject to rapid and significant change. While we believe that our team’s extensive pharmaceutical development and commercialization
experience launching successful drugs across multiple therapeutic areas, scientific knowledge, and global industry relationships provide us with competitive advantages, we
face  competition  from  other  pharmaceutical  and  biotechnology  companies,  including  Eli  Lilly  and  Company,  specialty  pharmaceutical  companies,  generic  drug  companies,
OTC companies, academic institutions, government agencies, and research institutions.

Many of our competitors have significantly greater financial, technical, and human resources than we do. Mergers and acquisitions in the pharmaceutical and biotechnology
industries may result in even more resources being concentrated amongst a smaller number of our competitors. Our commercial opportunity could be reduced or eliminated if
our  competitors  develop  or  market  products  or  other  novel  therapies  that  are  more  effective,  safer,  or  less  costly  than  our  current  or  future  product  candidates  or  obtain
regulatory approval for their products more rapidly than we may obtain approval for our product candidates. Our success will be based in part on our ability to identify, develop
and manage a patented portfolio of product

12

candidates that are safer and more effective than competing products and which will transform the lives of patients suffering from debilitating, chronic skin disorders that do not
go away, even with conventional treatment options.

Competition in Hyperhidrosis

If approved for the treatment of primary axillary hyperhidrosis, we anticipate that sofpironium bromide would compete with other therapies used for hyperhidrosis, including:

•

•

•

Self-Administered Treatments. Self-administered treatments, such as OTC and prescription topical antiperspirants, and Qbrexza  (glycopyrronium) 2.4% cloth. Oral and
compounded topical anticholinergics could be used off-label by administering physicians.

®

®
Non-Surgical Office-Based Procedures. Office-based procedures have been approved for the treatment of hyperhidrosis, including intradermal injections of BOTOX ,
marketed by AbbVie Inc., and MiraDry , a microwave-based treatment marketed by Miramar Labs, Inc.

®

Surgical Treatments. Surgical treatments include techniques for the removal of sweat glands, such as excision, curettage, and liposuction. Surgical procedures, such as
endoscopic thoracic sympathectomy, are also used to destroy nerves that transmit activating signals to sweat glands.

In addition to approved and off-label hyperhidrosis treatments, there are also several treatments currently under development that could potentially be used to treat hyperhidrosis
and may compete directly with sofpironium bromide.

Intellectual Property and In-Licensing Agreements

Our success depends in large part upon our ability to secure proprietary protection for our products and technologies, including those in development, 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
threats, evaluate and take appropriate courses of action.

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.

We also intend to use regulatory exclusivity (also called data package exclusivity), or depending on eligibility, orphan drug designation, as a means of acquiring intellectual
property protections that are separate and distinct to patents for some of our pipeline candidates. These kinds of rights involve being given exclusivity for varying periods of
time depending on the country to incentivize innovators who invest significant funds in and conduct clinical trials to produce necessary data to demonstrate a drug is safe and
effective for its intended use(s) and, as such, the data package in an NDA for the FDA (or similar regulatory filings in other countries) should receive protection even if no patent
is available, or exclusivity given to produce a treatment for a disease that otherwise would not realistically be invested in without such incentive. In addition, there are other
forms of intellectual property protection we may seek worldwide, including but not limited to trademarks, copyrights, trade secrets, pediatric exclusivity and the like, where
available and appropriate for our business interests.

We  further  protect  our  proprietary  information  by  requiring  our  directors,  officers,  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 our Company without adequate permission to do so. In addition, we require confidentiality or service agreements from third parties that
receive our confidential information or materials.

As of December 31, 2020, regarding our complete patent portfolio, we own or possess an exclusive license to  24  issued  U.S.  patents  and  100  issued  foreign  patents,  which
include granted European patent rights that have been validated in various European Union member states. We also own or possess an exclusive license to 13 pending U.S.
patent  applications  and  86  pending  international  and  foreign  patent  applications.  With  regard  to  our  lead  product  candidate,  sofpironium  bromide,  we  own  or  possess  an
exclusive license to nine issued U.S. and 85 issued foreign patents as well as 12 pending U.S. and 82 pending foreign patent applications which, if issued, may provide patent
term coverage until 2040 in certain cases and countries.

Table of Contents

Together with Kaken, we were granted by the Japanese Patent Office a composition of matter patent with claims directed to the novel polymorphic, or crystalline, forms of
sofpironium  bromide  that  are  being  commercialized  by  Kaken  in  Japan  and  would  be  by  us  in  the  U.S.  subject  to  our  own  ongoing  development  efforts,  and  this  patent  is
expected to provide additional protection for these newly developed and distinct forms in certain countries, including Japan, potentially through 2040.

We  aim  to  take  advantage  of  a  broad  range  of  the  intellectual  property  rights  that  are  available  to  us  and  believe  that  this  comprehensive  approach  will  provide  us  with
proprietary exclusive positions for our product candidates, where available.

Amended and Restated License Agreement with Bodor

In February 2020, we, together with Brickell Subsidiary and Bodor Laboratories, Inc. and Dr. Nicholas S. Bodor (collectively, “Bodor”) entered into an amended and restated
license agreement (the “Amended and Restated License Agreement”). The Amended and Restated License Agreement supersedes the License Agreement, dated December 15,
2012, entered into between Brickell Subsidiary and Bodor, as amended by Amendment No. 1 to License Agreement, effective as of October 21, 2013, and Amendment No. 2 to
License Agreement, effective as of March 31, 2015.

The Amended and Restated License Agreement retains with us a worldwide, exclusive license to develop, manufacture, market, sell, and sublicense products containing the
proprietary compound sofpironium bromide based upon the patents referenced in the Amended and Restated License Agreement for a defined field of use. In exchange for
entering into the Amended and Restated License Agreement, settling the previously disclosed dispute, and resolving the associated litigation between us and Bodor, we made
an upfront payment of $1.0 million in cash to Bodor following the execution of the Amended and Restated License Agreement and the settlement agreement by and among the
Company, Brickell Subsidiary, and Bodor, dated February 17, 2020. Additionally, under the original License Agreement and the Amended and Restated License Agreement, we
are required to pay Bodor (i) a royalty on sales of product outside Kaken’s territory, including a low single-digit royalty on sales of certain product not covered by the patent
estate  licensed  from  Bodor;  (ii)  a  specified  percentage  of  all  royalties  we  receive  from  Kaken  for  sales  of  product  within  its  territory;  (iii)  a  percentage  of  non-royalty
sublicensing  income  we  receive  from  Kaken  or  other  sublicensees;  and  (iv)  up  to  an  aggregate  of  $1.8  million  (plus  an  additional  $0.1  million  for  approvals  of  additional
products)  in  cash  payments  and  $1.5  million  of  shares  of  our  common  stock  upon  the  achievement  of  certain  development,  regulatory  and  other  milestones  including  the
enrollment of the first patient in the U.S. Phase 3 trials. Based on the foregoing, we made a $0.5 million milestone payment to Bodor in June 2020 following the closing of our
public offering in June 2020. Additionally, in October 2020, in association with the enrollment of the first patient in our U.S. Phase 3 pivotal program, we made a cash payment
of $0.5 million and issued $0.5 million, or 480,769 shares, of our common stock to Bodor. As a result, during the year ended December 31, 2020, we recorded an aggregate of
$1.5  million  as  research  and  development  expense  in  the  consolidated  statements  of  operations.  Further,  following  December  31,  2020,  we  have  begun  to  pay  Bodor  the
required royalties based on the royalty revenue we have recognized from Kaken’s net sales of sofpironium bromide in Japan.

Manufacturing and Supply

We currently contract with third parties for the manufacture of drug substances and drug products for use in nonclinical and clinical studies, and we intend to continue to do so
in  the  future.  To  our  knowledge,  all  of  our  clinical  drug  substance  and  drug  product  manufacturing  activities  are  in  compliance  with  current  good  manufacturing  practice
(“cGMP”).  We  have  assembled  a  team  of  experienced  employees  and  consultants  to  provide  the  necessary  technical,  quality,  and  regulatory  oversight  over  the  contract
manufacturing  organizations  (“CMOs”)  with  which  we  contract.  We  rely  on  third-party  cGMP  manufacturers  for  scale-up  and  process  development  work  and  to  produce
sufficient quantities of development product candidates for use in nonclinical and clinical studies.

Government Regulation

FDA Drug Approval Process

In the U.S., prescription human drugs are subject to extensive regulation by the FDA. The Federal Food, Drug, and Cosmetic Act (the “FDC Act”) and other federal and state
statutes  and  regulations  govern,  among  other  things,  the  research,  development,  testing,  manufacture,  storage,  recordkeeping,  approval,  labeling,  advertising,  promotion  and
marketing,  distribution,  post-approval  monitoring  and  reporting,  sampling  and  import  and  export  of  pharmaceutical  products.  Failure  to  comply  with  applicable  U.S.
requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending NDAs, warning or untitled letters, product
recalls, product seizures, total or partial

14

Table of Contents

suspension of production or distribution, injunctions, fines, civil penalties, corporate integrity agreements, and criminal prosecution.

Pharmaceutical product development for a new product or certain changes to an approved product in the U.S. typically involves nonclinical laboratory and animal tests, the
submission  to  the  FDA  of  an  Investigational  New  Drug  Exemption  (“IND”),  which  must  become  effective  before  clinical  testing  may  commence,  and  adequate  and  well-
controlled clinical trials to establish the safety and effectiveness of the drug for each indication for which FDA approval is sought. In addition, other tests on the chemistry,
manufacturing, and controls (“CMC”) of producing the drug and its various formulations to establish the shelf life, storage conditions, and quality parameters and specification
must be conducted and submitted.

Satisfaction of FDA pre-market approval requirements typically takes many years and the actual time required may vary substantially based upon the type, complexity, and
novelty  of  the  product  or  disease.  Nonclinical  tests  include  laboratory  evaluation  of  product  chemistry,  formulation,  and  toxicity,  as  well  as  animal  trials  to  assess  the
characteristics and potential safety and efficacy of the product. The conduct of the nonclinical tests must comply with federal regulations and requirements, including current
good laboratory practice (“GLP”) regulation. The results of nonclinical testing are submitted to the FDA as part of an IND along with other information, including information
about product CMC described above and a proposed clinical trial protocol. Long-term nonclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may
continue after the IND is submitted.

A  30-day  waiting  period  after  the  submission  of  each  IND  is  required  prior  to  the  commencement  of  clinical  testing  in  humans.  If  the  FDA  has  neither  commented  on  nor
questioned the IND within this 30-day period, the IND is considered in effect, and the clinical trial proposed in the IND may begin.

Clinical trials involve the administration of the investigational new drug to healthy subjects or patients under the supervision of a qualified physician investigator. Clinical trials
must be conducted (1) in compliance with federal and state regulations; (2) in compliance with current good clinical practice (“cGCP”) regulations, an international standard (as
adopted  by  FDA)  meant  to  protect  the  rights  and  health  of  patients  and  to  define  the  roles  of  clinical  trial  sponsors,  administrators,  and  monitors;  and  (3)  under  protocols
detailing the objectives of the trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated as well as the actual primary and secondary
endpoints of the study to be evaluated. Each protocol involving testing on U.S. patients and subsequent protocol amendments must be submitted to the FDA as part of the IND.

The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is not being
conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial participants. The study protocol and informed consent information for
patients in clinical trials must also be submitted to a local or central institutional review board (“IRB”) (outside the U.S., these are called Ethics Committees) for approval and
oversight. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the IRB’s requirements, or may impose
other conditions.

Clinical trials to support NDAs for marketing approval are typically conducted in three sequential phases, but the phases may overlap or in rarer cases early phases may be
skipped depending on the amount and quality of data that exists. In Phase 1, the initial introduction of the drug into healthy human subjects or patients, the drug is tested to
assess  pharmacological  actions,  metabolism,  pharmacokinetics,  adverse  effects  associated  with  administration  of  the  investigational  drug  and,  if  possible,  early  evidence  of
effectiveness. Phase 2 usually involves trials in a limited patient population to determine the effectiveness of the drug for a particular indication, dosage tolerance, and optimum
dosage, and to identify common adverse effects and safety risks. If a compound demonstrates evidence of effectiveness and an acceptable safety profile in Phase 2 evaluations,
Phase 3 clinical trials are undertaken to obtain the additional information about clinical efficacy and safety in a larger number of patients, typically at geographically dispersed
clinical trial sites, to permit the FDA to evaluate the overall benefit-risk relationship of the drug and to provide adequate information for the labeling of the drug. In most cases,
the FDA requires two adequate and well-controlled prospective Phase 3 clinical trials with statistically significant results to demonstrate the efficacy of the drug by comparing a
treatment arm against a control (placebo or best supportive care) arm. A single Phase 3 clinical trial with other confirmatory evidence may be sufficient in rare instances for
FDA registration where the study is a large multicenter trial demonstrating internal consistency and a statistically very persuasive finding of an effect on mortality, irreversible
morbidity, or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically impossible or ethically problematic.

Currently, our lead asset, sofpironium bromide, is being investigated in the U.S. for the treatment of primary axillary hyperhidrosis. Patients are being enrolled in two Phase 3
registration trials at the time of the filing of this Annual Report, called the Cardigan I and II studies. A long-term safety study on sofpironium bromide has already completed,
along with Phase 1 and Phase 2 clinical trials, and are expected to be part of an NDA submission to FDA at the appropriate time.

After  completion  of  required  clinical  testing,  applicable  law  requires  that  an  NDA  be  prepared  and  submitted  to  the  FDA.  FDA  approval  of  the  NDA  is  required  before
marketing of the product may begin in the U.S., which will be the case for sofpironium bromide. The NDA must include the results of all nonclinical, clinical, and other testing
and a compilation of data relating to the product’s pharmacology and CMC. The cost of preparing and submitting an NDA is substantial. The submission of most NDAs is
additionally subject to a substantial application user fee, and the manufacturer and sponsor under an approved NDA are also subject to annual product and establishment user
fees. These fees are typically increased annually. In the case of sofpironium bromide, payment of a user fee is not expected to be required for filing of an initial NDA, because
FDA guidance waives, or reduces, user fees for, among other things, a small business applicant, like us, submitting its first NDA.

The  FDA  has  60  days  from  its  receipt  of  an  NDA  to  determine  whether  the  application  will  be  accepted  for  filing  based  on  the  agency’s  threshold  determination  that  it  is
sufficiently  complete  to  permit  substantive  review.  Once  the  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review.  The  FDA  has  agreed  with  Congress  to
certain  performance  goals  in  the  review  of  NDAs.  Priority  review  can  be  applied  to  drugs  that  treat  a  serious  condition  and,  if  approved,  would  provide  a  significant
improvement in safety or effectiveness. In addition, FDA provides an accelerated approval mechanism applied to investigational drugs for serious or life-threatening diseases. It
is not expected that sofpironium bromide will be eligible for priority review, or accelerated approval, based on the present criteria. The review process for both standard and
priority review may be extended by the FDA for three additional months to consider certain late-submitted information, or information intended to clarify information already
provided in the submission.

The FDA also may refer applications for novel drug products, or drug products that present difficult questions of safety or efficacy, to an advisory committee, typically a panel
that includes independent clinicians and other experts in the targeted disease, for review, evaluation, and a recommendation as to whether the application should be approved.
The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. It is not known at this time whether FDA will require
an advisory committee for review of any NDA that may be submitted for sofpironium bromide, and that decision will be made by FDA during the NDA review.

Before approving an NDA, the FDA will typically inspect one or more of the sponsor’s clinical sites to assure compliance with cGCPs. Additionally, the FDA will generally
inspect the facility or the facilities at which the drug is manufactured. The FDA will not approve the product unless compliance with cGMP is satisfactory and the NDA contains
data sufficient to support the labeled shelf life and to demonstrate that the drug can be manufactured reliably in a controlled manner.

After the FDA evaluates the NDA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines
the  deficiencies  in  the  submission  and  may  require  substantial  additional  testing,  or  information,  in  order  for  the  FDA  to  reconsider  the  application.  If,  or  when,  those
deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will issue an approval letter. The FDA has committed to reviewing such
resubmissions in two or six months depending on the type of information required.

An approval letter authorizes commercial marketing of the drug in the U.S. with specific prescribing information for specific indications. The approval letter may contain safety
information that limits the ability of the drug to be marketed (e.g., black box warning; although these are not expected for sofpironium bromide) or contains contraindications,
warnings, and/or precautions that limit the potential of the drug’s desirability (these are standard for most approved drugs). As another potential condition of NDA approval, the
FDA  may  require  a  risk  evaluation  and  mitigation  strategy  (“REMS”)  for  drugs  that  are  effective  but  also  have  potentially  significant  safety  concerns.  REMS  can  include
medication guides, communication plans for healthcare professionals, and elements to assure safe use (“ETASU”). ETASU can include, but are not limited to, special training
or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring, and the use of patient registries. The requirement for a REMS can
materially affect the potential market and profitability of the drug. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the
drug’s safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following
initial marketing and/or manufacturing.

16

Table of Contents

Changes  to  some  of  the  conditions  established  in  an  approved  application,  including  changes  in  indications,  labeling,  or  manufacturing  processes  or  facilities,  require
submission and FDA approval of a new NDA or NDA supplement before the change can be implemented. An NDA supplement for a new indication typically requires clinical
data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in reviewing NDAs.

Post-Approval Requirements

Once an NDA is approved, a product will be subject to certain post-approval requirements. For instance, the FDA closely regulates, in part, the post-approval marketing and
promotion  of  drugs,  including  standards  and  regulations  for  direct-to-consumer  advertising,  social  media,  off-label  promotion,  formulary  and  reimbursement  presentations,
product sampling, sales force activities including dissemination of peer-reviewed journal articles and detailing practices with prescribers, health care practitioner interactions,
industry-sponsored scientific and educational activities, other promotional activities involving the internet and to other press, publicity and media communications initiated by
us, while other parts of the government regulate against false claims, foreign corrupt practices, trade sanctions, and anti-kickbacks. States often impose strict legal requirements
and prohibitions on a variety of post-approval drug marketing practices. We may market drugs holding an approved NDA only for the permitted indications and in accordance
with the provisions of the approved labeling.

Adverse event reporting, pharmacovigilance, and submission of periodic reports are required of the NDA holder following FDA approval of that NDA. The FDA also may
require post-marketing testing, known as Phase 4 testing, the aforementioned REMS and surveillance to monitor the effects of an approved product, or the FDA may place
conditions on an approval that could restrict the distribution or use of the product especially in the U.S. In addition, quality-control, drug manufacture, packaging, and labeling
procedures must continue to conform to cGMPs after approval. Drug manufacturers and certain of their subcontractors are required to register their establishments with the FDA
and  certain  state  agencies.  Registration  with  the  FDA  subjects  entities  to  periodic  unannounced  inspections  by  the  FDA,  during  which  the  agency  inspects  manufacturing
facilities  to  assess  compliance  with  cGMPs. Accordingly,  manufacturers  must  continue  to  expend  time,  money,  and  effort  in  the  areas  of  production  and  quality-control  to
maintain compliance with cGMPs or risk being sanctioned by FDA from supplying the drugs they manufacture. Regulatory authorities also may withdraw product approvals or
request product recalls if a company fails to comply with regulatory standards, if it encounters problems following initial marketing and supply, or if previously unrecognized
problems are subsequently discovered.

The Hatch-Waxman Act

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. Upon approval of a drug,
each of the patents listed in the application for the drug is then published in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known
as the “Orange Book.” Drugs listed in the Orange Book can, in turn, be cited by potential generic competitors in support of approval of an abbreviated new drug application
(“ANDA”). An ANDA provides for marketing of a drug product that has the same active ingredients in the same strengths and dosage form as the listed drug and has been
shown  through  bioequivalence  testing  to  be  therapeutically  equivalent  to  the  listed  drug.  Other  than  the  requirement  for  bioequivalence  testing, ANDA  applicants  are  not
required to conduct, or submit results of, nonclinical or clinical studies to prove the safety or effectiveness of their drug product. Drugs approved in this way are commonly
referred to as “generic equivalents” to the listed drug and can often be substituted by pharmacists under prescriptions written for the original listed drug and may be required to
be switched to from the original innovator drug by certain laws or insurance and formulary practices, which can affect the profitability of the drug adversely.

To proceed forward, the ANDA applicant is required to certify to the FDA concerning any patents listed for the approved product in the FDA’s Orange Book. Specifically, the
applicant must certify that (1) the required patent information has not been filed; (2) the listed patent has expired; (3) the listed patent has not expired, but will expire on a
particular date and approval is sought after patent expiration; or (4) the listed patent is invalid or will not be infringed by the new product. The ANDA applicant also may elect
to  submit  a  section  viii  statement  certifying  that  its  proposed ANDA  label  does  not  contain  (or  carves  out)  any  language  regarding  the  patented  method-of-use  rather  than
certify to a listed method-of-use patent. If the applicant does not challenge the listed patents, the ANDA 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 applicant has provided a Paragraph IV certification to the FDA,

17

Table of Contents

the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and
patent holders may then commence a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within
45  days  of  the  receipt  of  a  Paragraph  IV  certification  automatically  prevents  the  FDA  from  approving  the ANDA  until  the  earlier  of  30  months,  expiration  of  the  patent,
settlement of the lawsuit, or a decision in the infringement case that is favorable to the ANDA applicant.

The ANDA also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the referenced product expires.

It is not known at this time whether and to what extent, or when, an ANDA applicant may emerge with respect to sofpironium bromide, or any other pipeline product in our
portfolio.

Regulatory Exclusivity

Upon  NDA  approval  of  a  new  chemical  entity  or  NCE,  which  is  a  drug  that  contains  no  active  molecule  that  has  been  approved  by  the  FDA  in  any  other  NDA,  that  drug
receives five years of marketing exclusivity in the U.S. during which the FDA cannot receive any ANDA seeking approval of a generic version of that drug. Certain changes to
a drug, such as the addition of a new indication to the package insert, are associated with a three-year period of exclusivity during which the FDA cannot approve an ANDA for
a generic drug that includes the change.

An ANDA may be submitted one year before NCE exclusivity expires if a Paragraph IV certification is filed. If there is no listed patent in the Orange Book, there may not be a
Paragraph IV certification and, thus, no ANDA may be filed before the expiration of the exclusivity period.

Patent Term Extension

After NDA approval, owners of relevant drug patents may apply for up to a five-year patent term extension in the U.S. The allowable patent term extension is calculated as half
of  the  drug’s  testing  phase,  the  time  between  IND  application  and  NDA  submission,  and  all  of  the  review  phase,  the  time  between  NDA  submission  and  approval,  up  to  a
maximum of five years. Only one extension may be granted per product per patent. The time can be shortened if the FDA determines that the applicant did not pursue approval
with due diligence. The total patent term after the extension may not exceed 14 years.

For patents that might expire during the application phase, the patent owner may request an interim patent extension. An interim patent extension increases the patent term by
one year and may be renewed up to four times. For each interim patent extension granted, the post-approval patent extension is reduced by one year. The director of the USPTO
must determine that approval of the drug covered by the patent for which a patent extension is being sought is likely. Interim patent extensions are not available for a drug for
which an NDA has not been submitted. As stated, we expect to file an NDA for sofpironium bromide if the Cardigan I and II studies are successful.

It is premature to know what, and if any, patent term extension that may be allowed would be at this time.

Pediatric Information

Under the Pediatric Research Equity Act, NDAs or supplements to NDAs must contain data to assess the safety and effectiveness of the drug for the claimed indications in all
relevant pediatric subpopulations and to support dosing and administration in each pediatric subpopulation for which the drug is safe and effective. The FDA may grant full or
partial  waivers,  or  deferrals,  for  submission  of  data.  We  are  studying  pediatric  populations  aged  nine  and  older  in  various  of  our  clinical  trials  for  sofpironium  bromide,
including the Cardigan I and II pivotal trials. We have a Pediatric Study Plan for sofpironium bromide agreed to with FDA.

The Best Pharmaceuticals for Children Act (“BPCA”) provides NDA holders a six-month extension of any exclusivity, patent or non-patent, for a drug if certain conditions are
met. Conditions for exclusivity include the FDA’s determination that information relating to the use of a new drug in the pediatric population may produce health benefits in
that population, the FDA making a written request for pediatric studies and the applicant agreeing to perform, and report on, the requested studies within the statutory timeframe.

Disclosure of Clinical Trial Information

Sponsors of clinical trials of FDA-regulated products, including drugs, are required to register and disclose certain clinical trial information, including when a clinical trial is
initiated  (often  on  www.clintrials.gov);  you  can  access  this  information  for  certain  Company  studies  including  several  involving  sofpironium  bromide  at  this  website.
Information related to the product, patient population, phase, type and scope of investigation, study sites and investigators and other aspects of the clinical trial is then made
public as part of the registration process. Sponsors are obligated also to discuss the results of their clinical trials after completion and industry trade association ethics guidelines
require publication of both favorable and unfavorable study results, which can affect the potential market for a drug. Disclosure of the results of these trials can be delayed until
the  new  product  or  new  indication  being  studied  has  been  approved.  Competitors  may  use  this  publicly  available  information  to  gain  knowledge  regarding  the  progress  of
development programs.

Regulation Outside of the U.S.

In addition to regulations in the U.S., we will be subject to regulations of other countries governing any clinical trials and commercial sales and distribution of our product
candidates,  as  well  as  extent,  scope,  and  enforceability  of  intellectual  property  rights  associated  with  the  product  candidate.  Whether  or  not  we  obtain  FDA  approval  for  a
product  like  sofpironium  bromide,  we,  or  our  local  partners,  must  obtain  approval  by  the  comparable  regulatory  authorities  of  countries  outside  of  the  U.S.  before  it  can
commence clinical trials in such countries and approval of the regulators of such countries or economic areas, such as the European Union, before we may market products in
those countries or areas. Certain countries outside of the U.S. have a process similar to the FDA’s that requires the submission of a clinical trial application (“CTA”), much like
the IND prior to the commencement of human clinical trials. In the European Union, for example, a CTA must be submitted to each country’s national health authority and an
independent ethics committee, much like the FDA and IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trial development
may proceed. The approval process and requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary greatly from place to place, and
the time may be longer or shorter than that required for FDA approval. In some cases, once the investigational drug is approved by a regulatory agency in certain established
markets, like the FDA in the U.S., other countries will allow a sponsor to rely on that other country’s approval and extend it, with the same terms and conditions, in the foreign
country and this may accelerate the introduction of the drug in foreign markets, where applicable (often called a free sales certificate (“FSC”), or also a CPP, process).

Under European Union regulatory systems, a company may submit marketing authorization applications either under a centralized or decentralized procedure. The centralized
procedure, which is compulsory for medicines produced by biotechnology or those medicines intended to treat AIDS, cancer, neurodegenerative disorders, or diabetes and is
optional for those medicines which are highly innovative, provides for the grant of a single marketing authorization that is valid for all European Union member states. The
decentralized procedure provides for mutual recognition of national approval decisions. Under this procedure, the holder of a national marketing authorization may submit an
application to the remaining member states. Within 90 days of receiving the applications and assessments report, each member state must decide whether to recognize approval.
If a member state does not recognize the marketing authorization, the disputed points are eventually referred to the European Commission, whose decision is binding on all
member states.

As discussed herein, our lead investigational product sofpironium bromide has received marketing authorization from Japan’s regulators issued to our local partner in Japan,
Kaken Pharmaceutical Co., Ltd. under Kaken’s trade name ECCLOCK . At the time of this disclosure, there are no other clinical trials or submissions pending in any other
country outside the U.S. for sofpironium bromide or any other Company pipeline product.

Anti-Kickback, False Claims Laws

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal laws in the U.S. have been applied to restrict or prohibit certain
marketing practices in the pharmaceutical industry. These laws include, among others, anti-kickback statutes, false claims statutes and other statutes pertaining to healthcare
fraud and abuse, and anticorruption. The federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting, or
receiving remuneration to induce, or in return for, purchasing, leasing, ordering, or arranging for the purchase, lease or order of any healthcare item or service reimbursable
under  Medicare,  Medicaid,  or  other  federally  financed  healthcare  programs.  The  Patient  Protection  and Affordable  Care Act,  as  amended  (“PPACA”),  amended  the  intent
element of the federal anti-kickback statute so that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it. This statute has been
interpreted to apply to arrangements between pharmaceutical

19

Table of Contents

manufacturers  on  the  one  hand  and  prescribers,  purchasers,  and  formulary  managers  on  the  other. Although  there  are  a  number  of  statutory  exceptions  and  regulatory  safe
harbors protecting certain common activities from prosecution or other regulatory sanctions, the exceptions  and  safe  harbors  are  drawn  narrowly,  and  practices  that  involve
remuneration intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor.

Federal false claims laws prohibit any person or entity from, among other things, knowingly presenting, or causing to be presented, a false claim for payment to the federal
government, or knowingly making, or causing to be made, a false statement to have a false claim paid. This includes claims made to programs where the federal government
reimburses,  such  as  Medicaid,  as  well  as  programs  where  the  federal  government  is  a  direct  purchaser,  such  as  when  it  purchases  off  the  Federal  Supply  Schedule.
Pharmaceutical and other healthcare companies have been prosecuted under these laws for, among other things, allegedly inflating drug prices they report to pricing services,
which in turn were used by the government to set Medicare and Medicaid reimbursement rates, and for allegedly providing free product to customers with the expectation that
the customers would bill federal programs for the product. In addition, certain marketing practices, including off-label promotion, also may violate federal false claims laws.
Additionally, PPACA amended the federal healthcare program anti-kickback statute such that a violation of that statute can serve as a basis for liability under certain federal
false claims laws.

The majority of U.S. states also have statutes or regulations similar to the federal anti-kickback law and false claims laws, which apply to items and services reimbursed under
Medicaid and other state programs, or, in several states, apply regardless of the payor.

Other  federal  statutes  pertaining  to  healthcare  fraud  and  abuse  include  the  civil  monetary  penalties  statute,  which  prohibits,  among  other  things,  the  offer  or  payment  of
remuneration to a Medicaid or Medicare beneficiary that the offeror or payor knows or should know is likely to influence the beneficiary to order or receive a reimbursable item
or service from a particular supplier, and the healthcare fraud and false statements statutes, which prohibit, among other things, knowingly and willfully executing or attempting
to execute a scheme to defraud any healthcare benefit program or obtain by means of false or fraudulent pretenses, representations, or promises any money or property owned
by or under the control of any healthcare benefit program in connection with the delivery of or payment for healthcare benefits, items, or services.

Violations  of  these  federal  healthcare  fraud  and  abuse  laws  are  punishable  in  the  U.S.  by  imprisonment,  criminal  fines,  civil  monetary  penalties,  and  exclusion  from
participation in federal healthcare programs.

Other Federal and State Regulatory Requirements

Under the Open Payments Rule, the Centers for Medicare & Medicaid Services requires certain manufacturers of prescription drugs to annually collect and report information
on payments or transfers of value to certain health care professionals, including physicians, and teaching hospitals, as well as certain ownership and investment interests held by
physicians  and  their  immediate  family  members.  Failure  to  submit  required  information  may  result  in  civil  monetary  penalties.  Other  countries  require  similar  reporting,
including France and Belgium, if the product is approved and marketed there. In addition, several states now require prescription drug companies to report expenses relating to
the marketing and promotion of drug products and to report gifts and payments to individual healthcare practitioners and entities in these states. Other states prohibit various
other  marketing-related  activities.  Still,  other  states  require  the  posting  of  information  relating  to  clinical  studies  and  their  outcomes.  In  addition,  California,  Connecticut,
Nevada,  and  Massachusetts  require  pharmaceutical  companies  to  implement  compliance  programs  and  marketing  codes.  Several  additional  states  are  considering  similar
proposals. Some of the state laws are broader in scope than federal laws. Compliance with these laws is difficult and time-consuming, and companies that do not comply with
these state laws face civil or other penalties.

Coverage and Reimbursement

Sales of our product candidates, if approved, by us or any potential commercial partners will depend, in part, on the extent to which such products will be covered by third-party
payors, such as government healthcare programs, commercial insurance, and managed healthcare organizations. These third-party payors are increasingly limiting coverage or
reducing reimbursements for medical products and services. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a
significant  portion  of  the  cost  of  our  products.  Sales  of  any  products  for  which  we  receive  regulatory  approval  for  commercial  sale  will  therefore  depend,  in  part,  on  the
availability of coverage and adequate reimbursement from third-party payors. Third-party payors include government authorities, managed care plans, private health insurers,
and other organizations.

20

Table of Contents

The  process  for  determining  whether  a  third-party  payor  will  provide  coverage  for  a  drug  typically  is  separate  from  the  process  for  setting  the  price  of  such  product  or  for
establishing  the  reimbursement  rate  that  the  payor  will  pay  for  the  product  once  coverage  is  approved.  Third-party  payors  may  limit  coverage  to  specific  products  on  an
approved list, also known as a formulary, which might not include all of the FDA-approved products for a particular indication. A decision by a third-party payor not to cover
our product candidates could reduce a physician’s willingness to prescribe our products once approved and have a material adverse effect on our sales, results of operations, and
financial condition. Moreover, a third-party payor’s decision to provide coverage for a drug does not imply that an adequate reimbursement rate will be approved. Adequate
third-party  reimbursement  may  not  be  available  to  enable  us  to  maintain  price  levels  sufficient  to  realize  an  appropriate  return  on  our  investment  in  product  development.
Additionally, coverage and reimbursement for products can differ significantly from payor to payor. One third-party payor’s decision to cover a particular medical product or
service does not ensure that other payors will also provide coverage for the medical product or service, or will provide coverage at an adequate reimbursement rate.

In addition, the U.S. government, state legislatures, and foreign governments have continued implementing cost-containment programs, including price controls, restrictions on
reimbursement, and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in
jurisdictions with existing controls and measures, could further limit our net revenue and results. Third-party payors are increasingly challenging the prices charged for medical
products and services, examining the medical necessity and reviewing the cost-effectiveness of drugs, in addition to questioning safety and efficacy. If these third-party payors
do not consider our products to be cost-effective compared to other available therapies, they may not cover our products after FDA approval or, if they do, the level of payment
may not be sufficient to allow us to sell our products at a profit.

®

In addition, in some non-U.S. jurisdictions, the proposed pricing for a product candidate must be approved before it may be lawfully marketed, such as was the case with our
partner Kaken in Japan for ECCLOCK , which received pricing approval earlier this year as described elsewhere in this disclosure statement. The requirements governing drug
pricing vary widely from country to country. For example, the European Union provides options for its member states to restrict the range of medicinal products for which their
national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the
medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be
no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for
any of our product candidates. Historically, product candidates launched in Japan and the European Union do not follow price structures of the U.S. and generally tend to be
significantly lower, even lower than pricing that might be obtainable in some emerging market countries.

Employees

As of December 31, 2020, we had 13 regular full-time employees. From time to time, we retain independent contractors. None of our employees is represented by a labor union
or covered by a collective bargaining agreement. We have not experienced any work stoppages, and we consider our relations with our employees to be excellent.

ITEM 1A. RISK FACTORS

Our  business,  financial  condition,  and  operating  results  may  be  affected  by  a  number  of  factors,  whether  currently  known  or  unknown,  including  but  not  limited  to  those
described below. Any one or more of such factors could directly or indirectly cause our actual results of operations and financial condition to vary materially from past or
anticipated future results of operations and financial condition. Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition,
results  of  operations,  and  stock  price.  The  following  information  should  be  read  in  conjunction  with  Part  II,  Item  7,  “Management’s  Discussion  and  Analysis  of  Financial
Condition and Results of Operations” and the

consolidated financial statements and related notes in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report.

Risks Related to Our Business Operations

Our business depends on the successful financing, clinical development, regulatory approval, and commercialization of sofpironium bromide.

The successful development, regulatory approval, and commercialization of sofpironium bromide requires significant additional financing and depends on a number of factors,
including but not limited to the following:

•

•

•

•

•

•

•

•

•

•

•

•

timely and successful completion of Phase 3 clinical trials in the U.S., which may be significantly costlier than we currently anticipate, be impacted by how successful
patient enrollment is, especially in a pandemic, and/or produce results that do not achieve the endpoints of the trials or which are ultimately deemed not to be clinically
meaningful;

whether we are required by the FDA or similar foreign regulatory agencies to conduct additional clinical trials beyond those currently planned to support the approval
and commercialization of sofpironium bromide;

achieving and maintaining, and, where applicable, ensuring that our third-party contractors achieve and maintain, compliance with our and their contractual obligations
and with all regulatory and legal requirements applicable to sofpironium bromide;

ability of third parties with which we contract to manufacture consistently adequate clinical trial and commercial supplies of sofpironium bromide, to remain in good
standing  with  regulatory  agencies  and  to  develop,  validate  and  maintain  or  supervise  commercially  viable  manufacturing  processes  that  are  compliant  with  FDA-
regulated cGMPs, and the product’s package insert;

a continued acceptable safety and tolerability profile during clinical development and following any approval of sofpironium bromide;

ability to obtain favorable labeling for sofpironium bromide through regulators that allows for successful commercialization, given the drug may be marketed only to the
extent approved by these regulatory authorities (unlike with most other industries);

ability  to  commercialize  sofpironium  bromide  successfully  in  the  U.S.  and  outside  Japan,  if  approved  for  marketing,  sale,  and  distribution  in  such  countries  and
territories, whether alone or in collaboration with Kaken or others;

ability of Kaken to commercialize sofpironium bromide successfully in Japan now that it has been approved and is being marketed;

acceptance  by  physicians,  insurers  and  payors,  and  patients  of  the  quality,  benefits,  safety,  and  efficacy  of  sofpironium  bromide,  if  approved,  including  relative  to
alternative and competing treatments and the next best standard of care;

existence of a regulatory and legal environment conducive to the success of sofpironium bromide;

ability to price sofpironium bromide to recover our development costs and generate a satisfactory profit margin; and

our ability and our partners’ ability to establish and enforce intellectual property rights in and to sofpironium bromide, including but not limited to patents and licenses.

If  we  do  not  achieve  one  or  more  of  these  factors,  many  of  which  are  beyond  our  reasonable  control,  in  a  timely  manner  or  at  all,  and  with  adequate  financing,  we  could
experience significant delays or an inability to obtain regulatory approvals or commercialize sofpironium bromide. Even if regulatory approvals are obtained, we may never be
able to successfully commercialize sofpironium bromide. Accordingly, we cannot assure you that we will be able to generate sufficient revenue through the sale of sofpironium
bromide, or any other asset, to continue our business.

Table of Contents

We have never conducted a pivotal Phase 3 clinical trial ourselves and may be unable to successfully do so for sofpironium bromide.

The conduct of a pivotal Phase 3 clinical trial is a long, expensive, complicated, uncertain, and highly regulated process. Although our employees have conducted successful
Phase 2 and Phase 3 clinical trials in the past across many therapeutic areas while employed at other companies, we as a company have not conducted a pivotal Phase 3 clinical
trial, and as a result, we may require more time and incur greater costs than we anticipate. We completed a Phase 3 long-term safety study for sofpironium bromide gel in July
2020, and we are presently conducting two pivotal Phase 3 clinical trials in subjects with primary axillary hyperhidrosis in the U.S. While we initiated the U.S. Phase 3 pivotal
program for sofpironium bromide gel, 15% in the fourth quarter of 2020, we may not be able to complete that program in a reasonable timeframe, or at all, including as a result
of an inability to enroll qualifying patients in a timely fashion. Failure to commence or complete, or delays in, our planned clinical trials would prevent us from, or delay us in,
obtaining regulatory approval of and commercializing sofpironium bromide and could prevent us from, or delay us in, receiving development- or regulatory-based milestone
payments and commercializing sofpironium bromide gel for the treatment of primary axillary hyperhidrosis, which would adversely impact our financial performance, as well
as put us in potential breach of material contracts for the licensing and development of sofpironium bromide, subjecting us to significant contract liabilities, including but not
limited to potential loss of rights in and to sofpironium bromide.

Clinical drug development for sofpironium bromide is expensive, time-consuming, and uncertain.

Clinical  development  for  sofpironium  bromide  is  expensive,  time-consuming,  difficult  to  design  and  implement,  and  its  outcome  is  inherently  uncertain.  Most  product
candidates that commence clinical trials are never approved by regulatory authorities for commercialization, and of those that are approved, many do not cover their costs of
development or ever generate a profit. In addition, we, any partner with which we currently or may in the future collaborate, the FDA, a local or central IRB, or other regulatory
authorities, including state and local agencies and counterpart agencies in foreign countries, may suspend, delay, extend, require modifications, or add additional requirements to
or terminate our clinical trials at any time.

In the case of sofpironium bromide, we are seeking to deliver sufficient concentrations of API, absorbed from the skin surface through the skin barrier to the targeted dermal
tissue to achieve the intended therapeutic effect, in this case treatment of primary axillary (underarm) hyperhidrosis. The topical route of administration may involve new dosage
forms, which can be difficult to develop and manufacture and may raise novel regulatory issues and result in development or review delays or inability to get the investigational
drug approved for use.

Use of PROs and gravimetric assessments in sofpironium bromide clinical trials may delay or adversely impact the development of sofpironium bromide gel or clinical trial
results or increase our development costs.

Due to the difficulty of objectively measuring the symptoms of hyperhidrosis in a clinical trial, which is the primary target of treatment for sofpironium bromide, PROs will
have  an  important  role  in  the  development  and  regulatory  approval  of  sofpironium  bromide.  PROs  involve  patients’  own  subjective  assessments  of  efficacy,  and  this
subjectivity increases the uncertainty of determining and achieving clinical endpoints and obtaining regulatory approval. Such assessments can be influenced by factors outside
of our reasonable control and can vary widely from day to day for a particular patient, and from patient to patient and site to site within a clinical trial, notwithstanding that
regulators may or may not accept PROs as part of the drug approval process. Additionally, gravimetric assessments of sweat production, another key clinical endpoint, may vary
significantly for a particular patient, and from patient to patient and site to site within a clinical trial or between separate clinical trials. The reduction, if any, in a patient’s GSP
has the potential for significant variability and uncertain outcomes. This potential for variability and uncertain outcomes may adversely impact our ability to achieve statistical
significance on our primary and secondary endpoints or may provide us with initial or subsequent results that are ultimately deemed not to be clinically meaningful or that do
not result in regulatory approval.

Sofpironium  bromide  may  cause  undesirable  side  effects  or  have  other  unexpected  properties  that  could  delay  or  prevent  its  regulatory  approval,  limit  the  commercial
profile of an approved label, or result in post-approval regulatory action.

Unforeseen side effects from sofpironium bromide could arise either during clinical development or, if approved, after it has been marketed. Undesirable side effects caused by
sofpironium bromide could cause us, any partners with which we may collaborate, or regulatory authorities to interrupt, extend, modify, delay, or halt clinical trials, or even
later

25

Table of Contents

commercialization, and could result in a more restrictive or narrower product label or the delay or denial of regulatory approval by the FDA or comparable foreign authorities,
or a product recall and/or cancellation.

Results of clinical trials could reveal a high and unacceptable severity and prevalence of side effects. In such an event, trials could be suspended or terminated, and the FDA or
comparable foreign regulatory authorities could order us to cease further development of or deny approval of sofpironium bromide for any or all targeted indications. The drug-
related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in product liability claims. Any of these occurrences may
expose us to liability or harm our business, financial condition, operating results, and prospects.

Additionally, if we or others identify undesirable side effects, or other previously unknown problems, caused by sofpironium bromide after obtaining U.S. or foreign regulatory
approval,  a  number  of  potentially  negative  consequences  could  result,  which  could  prevent  us  or  our  potential  partners  from  achieving  or  maintaining  regulatory  approval
and/or market acceptance of sofpironium bromide and could substantially increase the costs (and extent) of commercializing sofpironium bromide, potentially even leading to
withdrawal of the drug.

Under our Clinical Supply Agreement with Kaken, our inability to obtain such API from Kaken on a timely basis could have a material adverse impact on our business.

On  July  30,  2019,  we  entered  into  a  Clinical  Supply Agreement  with  Kaken  (the  “Clinical  Supply Agreement”)  under  which  we  made  various  purchase  orders  for  certain
amounts of drug substance and product components for use in non-clinical and clinical studies, as well as for scale-up validation activities. Failure to receive such API from
Kaken on a timely basis could have a material impact on our business. Furthermore, at this time, we do not have a commercial supply agreement with Kaken or other suppliers.
Our inability to enter into an adequate commercial supply agreement at the right time for sofpironium bromide for the U.S. and other markets outside of Japan and certain other
Asian countries would materially impact our business.

Kaken substantially controls the development and commercialization of sofpironium bromide in Japan and certain other Asian countries and may make decisions regarding
product development, regulatory strategy, and commercialization that may not be in our best interests. Kaken may be unable to secure an appropriate local business partner
(if desirable) and/or obtain approval of the drug in the ex-Japan Asian markets over which it has rights.

The Kaken Agreement granted Kaken an exclusive Japan license and certain rights to additional Asian countries to develop and commercialize sofpironium bromide. Under the
terms of the Kaken Agreement, as amended, we received an up-front payment, development milestones, and research and development payments and are eligible to receive
future milestones and a royalty on net sales.

Kaken has final decision-making authority for the overall regulatory, development, and commercialization strategy for sofpironium bromide, market access activities, pricing
and reimbursement activities, promotion, distribution, packaging, sales, and safety and pharmacovigilance in Japan and certain other Asian countries. In exercising its final
decision-making  authority  in  such  territories,  Kaken  may  make  decisions  regarding  product  development  or  regulatory  strategy  based  on  its  determination  of  how  best  to
preserve and extend regulatory approvals in these territories for sofpironium bromide, which may delay or prevent achieving regulatory approval for sofpironium bromide in
Kaken’s  territories,  as  well  as  by  us  in  the  U.S.  and  the  other  territories  where  we  maintain  exclusive  rights. Additionally,  Kaken  is  responsible  for  conducting  certain
nonclinical and API-related activities (chemistry, manufacturing, and controls) that will be required for FDA approval in the U.S., and as a result, we are reliant on Kaken to
execute successfully, in a timely, compliant, and efficient manner, such activities on our behalf. To the extent Kaken experiences delays and/or difficulties in performing its
development activities, this could prevent or cause substantial delays in our ability to seek approval for sofpironium bromide gel in the U.S. and other territories in which we
maintain exclusive rights.

®
In September 2020, Kaken received approval of an NDA in Japan for the manufacturing and marketing of sofpironium bromide gel, 5% under the brand name ECCLOCK
for the treatment of primary axillary hyperhidrosis, and in November 2020, Kaken launched commercial sales of ECCLOCK  in Japan. In January 2021, Kaken would have
paid  us  its  first  royalty  on  sales  during  the  fourth  quarter  of  2020,  but  instead  offset  amounts  we  owed  Kaken  under  the  Clinical  Supply Agreement.  Despite  receiving
regulatory approval and commencing these commercial activities in Japan, we cannot provide any assurance that an NDA in any other Asian markets will be approved or that
regulatory approvals in other Asian countries will occur. We will not receive additional milestone or other payments from Kaken if Kaken does not

continue to be successful in its development, regulatory, or commercial activities, or if the approval is withdrawn for any reason.

If  we  or  any  partners  with  which  we  may  collaborate  to  market  and  sell  sofpironium  bromide  are  unable  to  achieve  and  maintain  medical  insurance  coverage  and
adequate levels of reimbursement for this compound following regulatory approval and usage by patients, our commercial success may be hindered severely.

If sofpironium bromide only becomes available by prescription, successful sales by us or by any partners with which we collaborate may depend on managed care approvals
and  the  availability  of  adequate  reimbursement  from  third-party  payors,  as  patients  would  then  be  forced  to  pay  for  the  drug  out-of-pocket  if  coverage  and  associated
reimbursement are denied. Patients who are prescribed medicine for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the costs
associated with their prescription drugs. The availability of coverage and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid in
the U.S., and private third-party payors is often critical to new product acceptance regardless of how well the product works. Coverage decisions may depend on clinical and
economic standards that disfavor new drug products when more established or lower-cost therapeutic alternatives are already available or subsequently become available, even
if these alternatives are not as safe and effective or may be affected by the budgets and demands on the various entities responsible for providing health insurance to patients
who will use sofpironium bromide. If insurers and payors decide that hyperhidrosis itself is not a disease they are willing to extend coverage to, which could happen if they
only  think  the  treatment  improves  quality  of  life,  then  coverage  and  reimbursement  for  sofpironium  bromide  may  be  denied,  or  at  least  severely  restricted.  In  this  case,
patients would be forced to pay for sofpironium bromide out-of-pocket for cash, which they may not be willing or able to do. Even if we obtain coverage for sofpironium
bromide,  the  resulting  reimbursement  payment  rates  might  not  be  adequate  or  may  require  co-payments  that  patients  find  unacceptably  high.  Patients  may  not  use
sofpironium bromide unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of sofpironium bromide.

In addition, the market for sofpironium bromide will depend significantly on access to third-party payors’ drug formularies or lists of medications for which third-party payors
provide coverage and reimbursement. The industry competition to be included in such formularies often leads to downward pricing pressures on pharmaceutical companies and
there may be time limitations on when a new drug may even be eligible for formulary inclusion. Also, third-party payors may refuse to include sofpironium bromide in their
formularies or otherwise restrict patient access to sofpironium bromide when a less costly generic equivalent or other treatment alternative is available in the discretion of the
formulary.

Third-party payors, whether foreign or domestic, or governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs. In the U.S.,
although private third-party payors tend to follow Medicare and Medicaid practices, no uniform or consistent policy of coverage and reimbursement for drug products exists
among third-party payors. Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor as well as state to state. Consequently, the
coverage determination process is often uncertain and a time-consuming and costly process that must be played out across many jurisdictions and different entities and which
will  require  us  to  provide  scientific,  clinical  and  health  economics  support  for  the  use  of  sofpironium  bromide  compared  to  current  alternatives  and  do  so  to  each  payor
separately, with no assurance that coverage and adequate reimbursement will be obtained and in what amount or time frame.

Further, we believe that future coverage and reimbursement likely will be subject to increased restrictions both in the U.S. and in international markets, potentially based on
changes in law and/or payor practices. Third-party coverage and reimbursement for sofpironium bromide may not be available or adequate in either the U.S. or international
markets, which could harm our business, financial condition, operating results, and prospects.

After receiving regulatory approval in 2020 for ECCLOCK  from Japanese regulators, Kaken applied for and received pricing approval in Japan, which it is required by law to
do  before  selling.  On  November  18,  2020,  ECCLOCK   was  placed  on  Japan’s  NHI  drug  reimbursement  price  list.  The  NHI  listed  drug  price  for  ECCLOCK   in  Japan  is
¥243.70 per gram, which is ¥4,874.00 (USD $46.47) for a 20-gram bottle or approximately a two-week supply. Kaken will likely face continued pricing pressures in Japan as it
commercializes ECCLOCK , and if it is unable to maintain this current price, or is unable to increase the price in future years, this could have a negative impact on sales in
Japan.

Even if sofpironium bromide obtains regulatory approval outside Japan, and despite our partner Kaken launching the drug as ECCLOCK  in Japan in 2020, it may fail to
achieve the broad degree of physician and patient adoption and use necessary for commercial success.

Table of Contents

The commercial success of sofpironium bromide, if and as approved, will depend significantly on the broad adoption and use of it  by  physicians  and  patients  for  approved
indications,  and  may  not  be  commercially  successful  even  though  the  drug  is  shown  to  be  safe  and  effective.  The  degree  and  rate  of  physician  and  patient  adoption  of
sofpironium bromide, if approved, especially in the U.S., will depend on a number of factors, including but not limited to:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

patient demand for approved products that treat hyperhidrosis;

our ability to market and sell the drug, including through direct-to-consumer advertising and non-traditional sales strategies;

our  ability  to  manage  the  COVID-19  pandemic  to  complete  necessary  clinical  trials,  supply/manufacture  sofpironium  bromide  for  such  trials  and  commercially,  and
otherwise market and sell sofpironium bromide while the pandemic continues in effect;

the safety and effectiveness of sofpironium bromide, and ease of use, compared to other available hyperhidrosis therapies, whether approved or used by physicians off-
label;

the availability of coverage and adequate reimbursement from managed care plans and other healthcare payors for sofpironium bromide;

the cost of treatment with sofpironium bromide in relation to alternative hyperhidrosis treatments and willingness to pay for sofpironium bromide, if approved, on the
part of patients;

overcoming physician or patient biases toward particular therapies for the treatment of hyperhidrosis and achieving acceptance by physicians, major operators of clinics
and patients of sofpironium bromide as a safe, effective, and economical hyperhidrosis treatment;

patients’ perception of hyperhidrosis as a disease and one for which medical treatment may be appropriate and a prescription therapy may be available;

insurers’ and physicians’ willingness to see hyperhidrosis as a disease worth treating and for which reimbursement will be made available for treatment;

proper administration of sofpironium bromide;

patient satisfaction with the results and administration of sofpironium bromide and overall treatment experience;

limitations or contraindications, warnings, precautions, or approved indications for use different than those sought by us that are contained in any final FDA-approved
labeling for sofpironium bromide;

any FDA requirement to undertake a REMS, or results from any post-marketing surveillance studies that FDA may require as a condition of product approval;

the effectiveness of our sales, marketing, pricing, reimbursement and access, government affairs, legal, medical, public relations, compliance, and distribution efforts;

adverse publicity about sofpironium bromide or favorable publicity about competitive products;

new government regulations and programs, including price controls and/or public or private institutional limits or prohibitions on ways to commercialize drugs, such as
increased scrutiny on direct-to-consumer advertising of pharmaceuticals or restrictions on sales representatives to market pharmaceuticals; and

potential  product  liability  claims  or  other  product-related  litigation  or  litigation  related  to  licensing  and  or  other  commercial  matters  associated  with  sofpironium
bromide.

If sofpironium bromide is approved for use but fails to achieve the broad degree of physician and patient adoption necessary for commercial success, our operating results and
financial condition will be adversely affected, which may delay, prevent, or limit our ability to generate revenue and continue our business.

Major public health issues, and specifically the pandemic caused by the spread of COVID-19 and COVID-19 variants that are recently emerging, could have an adverse
impact on our financial condition and results of operations and other aspects of our business and that of our suppliers, contractors, and business partners.

The extent to which COVID-19 impacts our business and operating results will depend on future developments that are highly uncertain and cannot be accurately predicted,
including new information that may emerge concerning COVID-19 and the actions to contain COVID-19 or treat its impact, among others.

The  effects  of  the  COVID-19  pandemic  could  delay  or  interrupt  our  business  operations.  For  instance,  our  clinical  trials  may  be  affected  by  the  pandemic.  Site  initiation,
participant  recruitment  and  enrollment,  participant  dosing,  manufacturing,  and  distribution  of  clinical  trial  materials,  study  monitoring,  and  data  analysis  may  be  paused  or
delayed due to changes in hospital or university policies, federal, state, or local regulations, prioritization of hospital resources toward pandemic efforts, or other reasons related
to  the  pandemic.  Some  participants  and  clinical  investigators  may  not  be  able  to  comply  with  clinical  trial  protocols.  For  example,  quarantines  or  other  travel  limitations
(whether voluntary or required) may impede participant movement, affect sponsor access to study sites, or interrupt healthcare services, and we may be unable to conduct our
clinical trials. Further, if our operations are adversely impacted, we risk a delay, default and/or nonperformance under existing agreements which may increase our costs. These
cost  increases  may  not  be  fully  recoverable  or  adequately  covered  by  insurance.  Infections  and  deaths  related  to  the  pandemic  may  disrupt  the  U.S.’  and  other  countries’
healthcare  and  healthcare  regulatory  systems.  Such  disruptions  could  divert  healthcare  resources  away  from,  or  materially  delay  FDA  or  other  regulatory  review  and/or
approval with respect to, our clinical trials. It is unknown how long these disruptions could continue, were they to occur. Any elongation or de-prioritization of our clinical trials
or delay in regulatory review resulting from such disruptions could materially affect the development and study of our product candidates.

We  currently  rely  on  third  parties,  such  as  contract  laboratories,  contract  research  organizations,  medical  institutions,  and  clinical  investigators  to  conduct  these  studies  and
clinical trials. If these third parties themselves are adversely impacted by restrictions resulting from the COVID-19 outbreak, we will likely experience delays, and/or realize
additional costs. As a result, our efforts to obtain regulatory approvals for, and to commercialize, our therapeutic candidates may be delayed or disrupted.

The spread of COVID-19, which has caused a broad impact globally, including restrictions on travel and quarantine policies put into place by businesses and governments, may
have a material economic effect on our business. While the potential economic impact brought by, and the duration of, the pandemic may be difficult to assess or predict, it has
already caused, and is likely to result in further, significant disruption of global financial markets, which may reduce our ability to access capital either at all or on favorable
terms. In addition, a recession, depression, or other sustained adverse market event resulting from the spread of COVID-19 could materially and adversely affect our business
and the value of our common stock.

The ultimate impact of the current pandemic, or any other health epidemic, is highly uncertain and subject to change. We cannot predict the full extent of potential delays or
impacts on our business, our clinical trials, our research programs, healthcare systems, or the global economy as a whole. However, these effects could have a material adverse
effect on our business, financial condition and results of operations, and cash flows.

Sofpironium bromide, if approved, will face significant competition and its failure to compete effectively may prevent it from achieving significant market penetration.

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition, less effective patent terms, and a strong emphasis on developing newer,
fast-to-market proprietary therapeutics. Numerous companies are engaged in the development, patenting, manufacturing, and marketing of healthcare products competitive with
those  that  we  are  developing,  including  sofpironium  bromide.  We  face  competition  from  a  number  of  sources,  such  as  pharmaceutical  companies,  generic  drug  companies,
biotechnology  companies,  and  academic  and  research  institutions,  many  of  which  have  greater  financial  resources,  marketing  capabilities,  sales  forces,  manufacturing
capabilities, research and development capabilities, regulatory expertise, clinical trial expertise, intellectual property portfolios, more international reach, experience in obtaining
patents and regulatory approvals for product candidates and other resources than us. Some of the companies that

29

Table of Contents

offer competing products also have a broad range of other product offerings, large direct sales forces, and long-term customer relationships with our target physicians, which
could inhibit our market penetration efforts. In addition, sofpironium bromide, if approved, may compete with other dermatological products, including OTC treatments, for a
share of some patients’, or payors’, discretionary budgets and for physicians’ attention within their clinical practices.

We anticipate that sofpironium bromide would compete with other therapies currently used for hyperhidrosis, including but not limited to:

•

•

•

Self-Administered Treatments. Self-administered treatments, such as OTC and prescription topical antiperspirants, and Qbrexza  (glycopyrronium) 2.4% topical cloth.
Oral and compounded topical anticholinergics also may be used off-label.

®

Non-Surgical  Office-Based  Procedures.  Office-based  procedures  have  been  approved  by  the  FDA  for  certain  uses  and  which  may  be  used,  on-or  off-label,  to  treat
hyperhidrosis, including intradermal injections of BOTOX , marketed by Allergan plc., and MiraDry , a microwave-based treatment marketed by Miramar Labs, Inc.

®

®

Surgical Treatments. Surgical treatments include techniques for the removal of sweat glands, such as excision, curettage, and liposuction. Surgical procedures, such as
endoscopic thoracic sympathectomy, are also used to destroy nerves that transmit activating signals to sweat glands.

To compete successfully in this market, we will have to provide an attractive and cost-effective alternative to these existing and other new therapies. Such competition could
lead to reduced market share for sofpironium bromide and contribute to downward pressure on the pricing of sofpironium bromide, which could harm our business, financial
condition, operating results, and prospects.

In some international markets, due to different regulatory requirements than in the U.S., there may be more dermatological products available for use than in the U.S., and there
may be fewer limitations on the claims that our competitors can make about the effectiveness of their products and the manner in which they can market them. As a result, we
could face more competition in these markets than in the U.S.

We may face generic competition for sofpironium bromide, which could expose us to litigation or adversely affect our business, financial condition, operating results, and
prospects.

Upon  expiration  of  patent  protection  (including  applicable  extensions)  in  the  U.S.  (and  any  other  countries  where  patent  coverage  exists,  such  as  Japan)  for  sofpironium
bromide, we could lose a significant portion of then-existing sales of sofpironium bromide in a short period of time from generic competition, which would reduce existing sales
and  could  expose  us  to  litigation,  adversely  affecting  our  business,  financial  condition,  operating  results,  and  prospects.  Further,  other  therapies  used  for  hyperhidrosis  that
would  compete  with  sofpironium  bromide  could  lose  their  patent  protection  at  any  time,  increasing  the  risk  of  generic  competition,  which  could  reduce  existing  sales  and
adversely affect our business, financial condition, operating results, and prospects.

If CROs and other third parties do not meet our requirements or otherwise conduct our clinical trials as required or are unable to staff our trials, or do not effectively and
timely enroll patients in these trials, particularly the ongoing U.S. registration trials, we may not be able to satisfy our contractual obligations or obtain regulatory approval
for, or commercialize, sofpironium bromide at all or in the time frames currently planned for.

We have in the past relied, and expect to continue to rely, on third-party CROs to conduct and oversee our sofpironium bromide clinical trials and other aspects of product
development. We also rely on various medical institutions, clinical investigators, and contract laboratories to conduct our trials in accordance with our clinical protocols and all
applicable regulatory requirements, including the FDA’s regulations and good GCP requirements, which are an international standard meant to protect the rights and health of
patients and to define the roles of clinical trial sponsors, administrators and monitors, and state regulations governing the handling, storage, security and recordkeeping for drug
and biologic products. These CROs and other third parties play a significant role in the conduct of these trials and the subsequent collection and analysis of data from the clinical
trials. We rely heavily on these parties for the execution of our clinical trials and preclinical studies, especially recruiting and enrollment of eligible patients, and control only
certain  aspects  of  their  activities.  We  and  our  CROs  and  other  third-party  contractors  are  required  to  comply  with  GCP  and  GLP  requirements,  which  are  regulations  and
guidelines enforced by the FDA and comparable foreign regulatory authorities for sofpironium bromide. Regulatory

30

Table of Contents

authorities enforce these GCP and GLP requirements through periodic inspections of trial sponsors, principal investigators, and trial sites. If we or any of these third parties fail
to comply with applicable GCP and GLP requirements, or reveal noncompliance from an audit or inspection, the clinical data generated in our clinical trials may be deemed
unreliable and the FDA or other regulatory authorities may require us to perform additional clinical trials before approving our or our partners’ marketing applications. We
cannot assure that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical or preclinical trials comply with applicable
GCP  and  GLP  requirements.  In  addition,  our  clinical  trials  generally  must  be  conducted  with  product  produced  under  cGMP  regulations.  Our  failure  to  comply  with  these
regulations and policies may require us to extend or repeat clinical trials, which would delay the regulatory approval process.

If any of our CROs or clinical trial sites terminate their involvement in one of our clinical trials for any reason, including but not limited to impacts caused by the ongoing
COVID-19  pandemic,  we  may  not  be  able  to  enter  into  arrangements  with  alternative  CROs  or  clinical  trial  sites,  or  do  so  on  commercially  reasonable  terms,  and  in  a
satisfactory timeframe. If our relationship with clinical trial sites is terminated, we may experience the loss of follow-up information on patients enrolled in our ongoing clinical
trials  unless  we  are  able  to  transfer  the  care  of  those  patients  to  another  qualified  clinical  trial  site.  In  addition,  principal  investigators  for  our  clinical  trials  may  serve  as
scientific advisors or consultants to us from time to time and could receive cash or equity compensation in connection with such services. If these relationships and any related
compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical trial site may be questioned by the FDA.

We currently have limited marketing capabilities and no sales organization. If we are unable to establish sales and marketing capabilities on our own or through third
parties, or are delayed in establishing these capabilities, we will be unable to successfully commercialize our product candidates, if approved, or generate product revenue.

We currently have limited marketing capabilities and no sales organization. To commercialize our product candidates, if approved, in the U.S., Australia, Canada, the European
Union, Latin America, Africa, the Middle East, and other jurisdictions we seek to enter, we must build our marketing, sales, distribution, managerial, and other non-technical
capabilities  or  make  arrangements  with  third  parties  to  perform  these  services,  and  we  may  not  be  successful  in  doing  so. Although  our  employees  have  experience  in  the
marketing, sale, and distribution of pharmaceutical products, and business development activities involving external alliances, from prior employment at other companies, we as
a company have no prior experience in the commercial launch, marketing, sale, and distribution of pharmaceutical products, and there are significant risks involved in building
and managing a sales organization, including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and
marketing personnel, and effectively manage a geographically dispersed sales and marketing team so they operate in an effective and compliant way. Any failure or delay in the
development of our internal sales, marketing, distribution, and pricing/reimbursement/access capabilities would impact adversely the commercialization of these products. In
addition, we may need more than one approved and marketed product to sustain having a Company salesforce.

To commercialize sofpironium bromide in the rest of the world, we may be able to leverage the regulatory approval and/or commercial infrastructure of our partner, Kaken,
which will provide us with resources and expertise in certain areas that are greater than we could initially provide ourselves. We may choose to collaborate with additional third
parties in various countries that have direct sales forces, commercial and regulatory capacities, and established distribution systems, either to augment our own sales force and
distribution systems or in lieu of our own sales force and distribution systems. If we are unable to enter into such arrangements on acceptable terms or at all, we may not be able
to successfully commercialize our product candidates, especially in other countries where we currently do not have a foreign legal presence. The inability to commercialize
successfully our product candidates, either on our own or through collaborations with one or more third parties, would harm our business, financial condition, operating results,
and prospects.

Our collaboration with AnGes may prove to be unsuccessful, either because AnGes is unable to timely develop its COVID-19 vaccine candidate, or because we are not able
to continue with this alliance for a variety of business, financial, or other reasons.

The COVID-19 vaccine candidate that is the subject of our collaboration agreement with AnGes, Inc. is at an early stage, and it may not result in a safe and effective product
candidate in a timely manner, or at all, it may not be deemed attractive by consumers given other COVID-19 vaccines are now in the market and available, there could be
supply chain issues for both clinical and commercial contexts, and we may not be able to proceed with related development and commercialization activities. Our contractual
relationship with AnGes may end in a variety of ways or we may be unable to negotiate additional

31

Table of Contents

acceptable terms with AnGes. Further, any attention and resources we devote to this vaccine candidate could negatively impact our development program related to sofpironium
bromide.

In September 2020, we entered into a collaboration agreement with AnGes relating to the development and potential commercialization of AnGes’ proprietary investigational
adjuvanted plasmid DNA vaccine intended to prevent COVID-19. Under the terms of the collaboration agreement, AnGes will continue to lead the development of its vaccine
candidate in Japan, and we will provide information and know-how that could be relevant to such development efforts. If AnGes obtains positive results from its clinical studies
in Japan and we are able to satisfy certain conditions, including raising the required development funding, we would have the right to lead the development efforts in the U.S.
and certain emerging markets. If ultimately approved for sale in the applicable jurisdictions, AnGes would have commercial rights to the vaccine in Japan and we would have
commercial rights in the U.S. and certain emerging markets on terms and conditions to be agreed with AnGes prior to any launch of a vaccine product.

AnGes completed a Phase 1/2 study and is currently conducting Phase 2/3 clinical studies with its vaccine candidate in Japan. The results from these studies will guide any
further  development  efforts  of  this  novel  vaccine  candidate.  Because  the AnGes  vaccine  candidate  is  later  in  its  development  than  other  vaccine  options  for  COVID-19,  its
potential for commercial success could be adversely affected, even if regulatory approval is obtained. The work on the AnGes vaccine candidate is still in the early stages, and it
may not develop into an effective and safe vaccine in a timely manner, or at all. All product candidates are prone to significant risks of failure typical of pharmaceutical product
development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by one or more regulatory authorities, or that
another vaccine option is deemed to be safer, better, more easily obtained, or cheaper. Some regulatory authorities may approve a product candidate while others do not or may
provide approval on different terms or with additional conditions or limitations, or may issue any regulatory approval decisions at very different times. The regulatory approval
processes of the FDA and comparable foreign authorities are lengthy, time consuming, costly, and inherently unpredictable, especially for early-stage product candidates. In
addition,  approval  policies,  regulations,  or  the  type  and  amount  of  clinical  data  necessary  to  gain  approval  may  change  during  the  course  of  a  product  candidate’s  clinical
development and may vary among jurisdictions. The development of any early-stage product candidates may be discontinued at any time for a variety of reasons, including but
not  limited  to  safety  and  efficacy  concerns,  the  appearance  of  new  technologies  that  make  the  product  obsolete,  competition  from  a  competing  product,  supply  chain
considerations, intellectual property right impacts, ability to price or changes in or failure to comply with applicable regulatory requirements, or constraints on us or our product
sponsor in obtaining additional financing and capital.

In addition, a substantial number of companies, individuals and institutions are working to develop, or have developed and are now distributing, a COVID-19 vaccine. Many of
them commenced studies much earlier than the studies commenced by AnGes and many of them have substantially greater financial, scientific and other resources than AnGes
and us, and another party may be successful in producing a safer or more efficacious vaccine or other treatment for COVID-19, or a less costly treatment, which may also lead
to  the  diversion  of  governmental  and  quasi-governmental  funding  toward  other  companies  and  better  insurance  coverage  for  other  COVID-19  preventative  measures  or
treatments, and lead to demand being driven away from any product developed by AnGes or us, or cause AnGes and/or us to cancel or significantly scale back the introduction
of a vaccine candidate based on the other available patient options. The current market entry of certain COVID-19 vaccines and rapid expansion of other development programs
directed  at  COVID-19  may  also  generate  a  scarcity  of  manufacturing  capacity  among  contract  research  organizations  that  provide  cGMP  materials  for  development  and
commercialization of biopharmaceutical products, and/or could make it difficult for those conducting clinical studies to recruit in a timely manner an adequate number of trial
participants, especially for companies like AnGes and us which started these studies much later than other companies.

We  do  not  have  expertise  in  the  development  of  vaccine  candidates  in  infectious  disease  applications.  While  we  remain  focused  on  our  U.S.  Phase  3  pivotal  program  for
sofpironium bromide for the treatment of primary axillary hyperhidrosis, the collaboration agreement with AnGes, including actions taken following the receipt of results from
AnGes’  clinical  studies  of  the  vaccine  candidate  in  Japan,  could  divert  our  management’s  attention  and  other  of  our  resources,  which  could  cause  delays  in  or  otherwise
negatively  impact  our  sofpironium  bromide  development  program. As  a  result,  we  cannot  provide  assurance  that  any  attention  we  provide  to  the  development  of  a  vaccine
candidate against COVID-19 will not adversely impact the timing and development of our other product candidates, and we may decide not to proceed with this collaboration
depending on many still evolving factors.

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

Despite the implementation of security measures, our internal computer systems and those of our current and future CROs and other contractors and consultants, and even the
regulators  who  we  rely  on  to  advance  our  business,  are  vulnerable  to  damage  from  computer  viruses,  unauthorized  access,  computer  hacking  or  breaches,  natural  disasters,
epidemics and pandemics, terrorism, war, labor unrest, and telecommunication and electrical failures. 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.  In  addition,  and  probably  exacerbated  by  the  COVID-19  pandemic  and  increased  remote  working
arrangements,  malicious  cyber  actors  may  increase  malware  campaigns  and  phishing  emails  targeting  teleworkers  as  well  as  company  systems,  preying  on  the  uncertainties
surrounding COVID-19, which exposes us to additional cybersecurity risks. While we have not experienced any such material system failure, accident, or security breach to
date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our development programs and our business operations.
In addition, since we sponsor clinical trials, any breach that compromises patient data and identities, thereby causing a breach of privacy, could generate significant reputational
damage and legal liabilities and costs to recover and repair, including affecting trust in us to recruit for future clinical trials. For example, the loss of clinical trial data from
completed, ongoing or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the
extent  that  any  disruption  or  security  breach  were  to  result  in  a  loss  of,  or  damage  to,  our  data  or  applications  or  inappropriate  disclosure  of  confidential  or  proprietary
information, we could incur liability and the further development and commercialization of our products and product candidates could be delayed.

We may be adversely affected by natural disasters and other catastrophic events and by man-made problems such as war or terrorism or labor disruptions that could disrupt
our business operations, and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our corporate office is located in Boulder, Colorado, near a major flood and blizzard zone and in an area prone to wildfires. If a disaster, power outage, or other event occurred
that prevented us from using all or a significant portion of our office, that damaged critical infrastructure, or that otherwise disrupted operations, it may be difficult or, in certain
cases, impossible for us to continue our business for a period of time. Our contract manufacturers’ and suppliers’ facilities are located in multiple locations where other natural
disasters  or  similar  events,  such  as  tornadoes,  earthquakes,  storms,  fires,  explosions  or  large-scale  accidents  or  power  outages,  could  severely  disrupt  our  operations,  could
expose us to liability and could have a material adverse effect on our business, financial condition, operating results, and prospects. All of the aforementioned risks may be
further increased if we do not implement a disaster recovery plan or our partners’ or manufacturers’ disaster recovery plans prove to be inadequate.

Risks Related to Our Liquidity, Financial Matters and Our Common Stock

We will need to raise substantial additional financing in the future to fund our operations and/or prepare an NDA submission in the U.S. for sofpironium bromide, which
may not be available to us on favorable terms or at all.

We will require substantial additional funds to develop and, if successful, commercialize our product candidates. Our future capital requirements will depend upon a number of
factors, including but not limited to: the number and timing of future product candidates in the pipeline; progress with and results from preclinical testing and clinical trials; the
ability  to  manufacture  sufficient  drug  supplies  to  complete  preclinical  and  clinical  trials;  the  costs  involved  in  preparing,  filing,  acquiring,  prosecuting,  maintaining  and
enforcing patent and other intellectual property claims; compliance with our material contracts including the licensing agreement for sofpironium bromide; the time and costs
involved in obtaining regulatory approvals and favorable reimbursement or formulary acceptance for such product candidates; and overall stock market and global business
conditions and trends.

Raising  additional  capital  may  be  costly  or  difficult  to  obtain  and  could  significantly  dilute  stockholders’  ownership  interests  or  inhibit  our  ability  to  achieve  our  business
objectives. Further, we will be significantly limited in our ability to utilize our common stock in any capital-raising transaction unless and until the number of authorized shares
of  our  common  stock  is  increased,  which  would  require  stockholder  approval.  If  we  raise  additional  funds  through  public  or  private  equity  offerings,  the  terms  of  these
securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Further, to the extent that we raise additional capital through
the sale of common stock or securities convertible

33

Table of Contents

or exchangeable into common stock, our stockholders’ ownership interests in our company will be diluted. In addition, any debt financing may subject us to fixed payment
obligations and 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 capital through marketing and distribution arrangements or other collaborations, strategic alliances, or licensing arrangements with third parties, we may have to
relinquish certain valuable intellectual property or other rights to our product candidates, technologies, future revenue streams or research programs or grant licenses on terms
that may not be favorable to us in one or more countries.

Our ability to raise additional funds is uncertain and is limited given our small market capitalization. Even if sufficient funding is available, there can be no assurance that it will
be available on terms acceptable to us or our stockholders.

Our operating results and liquidity needs could be affected negatively by global market fluctuations and economic downturns.

Our operating results and liquidity could be affected negatively by global economic conditions generally, both in the U.S. and elsewhere around the world, including but not
limited  to  that  related  to  the  ongoing  COVID-19  pandemic.  The  market  for  discretionary  pharmaceutical  products,  medical  devices,  and  procedures  may  be  particularly
vulnerable to unfavorable economic conditions. Some patients may consider sofpironium bromide as discretionary, and if full reimbursement for the product is not available,
demand for the product may be tied to the discretionary, out-of-pocket cash-spending levels of our targeted patient populations. Domestic and international equity and debt
markets have experienced and may continue to experience heightened volatility and turmoil based on domestic and international economic conditions and concerns. In the event
these economic conditions and concerns continue or worsen and the markets continue to remain volatile, or a bear market ensues in the U.S. stock market, including as a result
of the recent COVID-19 outbreak, our operating results and liquidity could be affected adversely by those factors in many ways, including weakening demand for sofpironium
bromide, making it more difficult for us to raise funds if necessary, and our stock price may decline.

Our stock price and volume of shares traded have been and may continue to be highly volatile, and our common stock may continue to be illiquid.

The market price of our common stock following the Merger has been subject to significant fluctuations. The closing price of our common stock fluctuated from $4.69 per
share as of September 3, 2019, the first trading date following the closing of the Merger, to $0.78 per share as of December 31, 2020. Between December 18, 2020 and March
4,  2021,  the  closing  price  of  our  common  stock  has  fluctuated  between  $0.69  and  $1.67  per  share.  Market  prices  for  securities  of  biotechnology  and  other  life  sciences
companies  historically  have  been  particularly  volatile  subject  even  to  large  daily  price  swings.  In  addition,  there  has  been  limited  liquidity  in  the  trading  market  for  our
securities, which may adversely affect stockholders. Some of the factors that may cause the market price of our common stock to continue to fluctuate include, but are not
limited to:

• material developments in, or the conclusion of, any litigation to enforce or defend any intellectual property rights or defend against the intellectual property rights of

others;

•

•

•

•

•

•

•

our  inability  to  maintain  a  share  price  of  at  least  $1.00  per  share  for  the  frequency  and  duration  required  by  The  Nasdaq  Capital  Market  to  stay  listed  on  this  stock
exchange and the impact that this lower price may have on investors;

the entry into, or termination of, or breach by us or our partners of material agreements, including key commercial partner or licensing agreements, including the Kaken
Agreement;

our ability to obtain timely regulatory approvals for sofpironium bromide or future product candidates, and delays or failures to obtain such approvals;

failure of sofpironium bromide, if approved, to achieve commercial success;

issues in manufacturing or the supply chain for sofpironium bromide or future product candidates;

the results of current and any future clinical trials of sofpironium bromide;

failure of other product candidates, if approved, to achieve commercial success;

34

Table of Contents

•

•

•

•

•

•

announcements of any dilutive equity financings;

announcements by commercial partners or competitors of new commercial products, clinical progress or the lack thereof, significant contracts, commercial relationships,
or capital commitments;

the introduction of technological innovations or new therapies or formulations that compete with sofpironium bromide;

lack of commercial success of competitive products or products treating the same or similar indications;

failure to elicit meaningful stock analyst coverage and downgrades of our stock by analysts; and

the loss of key employees and/or inability to recruit the necessary talent for new positions or to replace exiting employees.

Moreover,  the  stock  markets  in  general  have  experienced  substantial  volatility  in  our  industry  that  has  often  been  unrelated  to  the  operating  performance  of  individual
companies or a certain industry segment, such as the recent reaction of global markets to the COVID-19 outbreak. These broad market fluctuations may also adversely affect
the trading price of our common stock.

In  the  past,  following  periods  of  volatility  in  the  market  price  of  a  company’s  securities,  shareholders  have  often  instituted  class  action  securities  litigation  against  those
companies. Such litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which could significantly harm our profitability
and reputation. Such securities litigation often has ensued after a reverse merger or other merger and acquisition activity of the type we completed in 2019. Such litigation, if
brought, could expose us to liability or impact negatively our business, financial condition, operating results, and prospects.

Our  operating  results  may  fluctuate  significantly,  which  makes  our  future  operating  results  difficult  to  predict  and  could  cause  our  operating  results  to  fall  below
expectations.

Our operations to date have been limited primarily to researching and developing sofpironium bromide and undertaking preclinical studies and clinical trials of sofpironium
bromide. Consequently, any predictions you or we make about our future success or viability may not be as accurate as they could be if we had a longer operating history or
approved products on the market. Our revenue and profitability will depend on development funding, the achievement of sales milestones and royalties under an agreement with
Kaken, as well as any potential future collaboration and license agreements and sales of sofpironium bromide or future products, if approved, and our ability to maintain the
related license. These up-front and milestone payments may vary significantly from period to period, and country to country, and any such variance could cause a significant
fluctuation in our operating results from one period to the next. In addition, we measure compensation cost for stock-based awards made to employees at the grant date of the
award, based on the fair value of the award, and recognize the cost as an expense over the employee’s requisite service period. As the variables that we use as a basis for valuing
these awards change over time, including our underlying stock price and stock price volatility, the magnitude of the expense that we must recognize may vary significantly.
Furthermore, our operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict.

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

We qualify as a “smaller reporting company” under Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As a smaller reporting company, we
are entitled to rely on certain exemptions and reduced disclosure requirements, such as simplified executive compensation disclosures and reduced financial statement disclosure
requirements,  in  our  SEC  filings.  These  exemptions  and  decreased  disclosures  in  our  SEC  filings  due  to  our  status  as  a  smaller  reporting  company  may  make  it  harder  for
investors  to  analyze  our  results  of  operations  and  financial  prospects.  We  cannot  predict  if  investors  will  find  our  common  stock  less  attractive  because  we  rely  on  these
exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our common stock price
may be more volatile.

If the holders of our company’s stock options and warrants exercise their rights to purchase our common stock, the ownership of our stockholders will be diluted.

If the holders of our outstanding stock options and warrants exercise their rights to acquire our common stock and service conditions related to restricted stock units are met,
the percentage ownership of our stockholders existing prior to the exercise of such rights will be diluted. As of December 31, 2020, we had outstanding warrants to purchase (i)
one share of our common stock at an exercise price of $0.07 per share; (ii) 490,683 shares of our common stock at an exercise price of $10.36 per share; (iii) 9,005 shares of
our common stock at an exercise price of $33.31 per share; (iv) 1,556,420 shares of our common stock at an exercise price of $1.16 per share; (v) 17,500,000 shares of our
common stock at an exercise price of $1.25 per share; and (vi) 20,833,322 shares of our common stock at an exercise price of $0.72 per share. As of December 31, 2020, we
also had 4,688,625 options issued and outstanding to purchase our common stock at a weighted-average exercise price of $4.66 per share and 143,000 shares of common stock
underlying unvested restricted stock units outstanding.

We may not be able to access the full amounts available under the Purchase Agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”), which could prevent us
from accessing the capital we need to continue our operations, which could have an adverse effect on our business.

On February 17, 2020, we entered into the Purchase Agreement with Lincoln Park pursuant to which Lincoln Park agreed to purchase from us up to an aggregate of $28.0
million  of  our  common  stock  (subject  to  certain  limitations)  from  time  to  time  over  the  36-month  period  commencing  on August  14,  2020. All  funds  available  under  the
Purchase Agreement are subject to the satisfaction of certain conditions specified in the Purchase Agreement, including that our common stock remains listed on The Nasdaq
Capital Market, the effectiveness of a registration statement relating to the resale of the shares to be sold to Lincoln Park under the Purchase Agreement and that no event of
default  has  occurred  under  the  Purchase Agreement. Additionally,  depending  upon  the  prevailing  market  price  of  our  common  stock,  we  may  not  be  able  to  sell  shares  to
Lincoln Park if such a sale would result in us issuing to Lincoln Park more than 9.99% of our shares outstanding prior to entering into the Purchase Agreement. Further, we will
be significantly limited in our ability to sell shares of our common stock under the Purchase Agreement unless and until the number of authorized shares of our common stock
is increased, which would require stockholder approval. In the event that we are unable to satisfy the conditions specified, the purchase commitment made by Lincoln Park will
be unavailable to us and Lincoln Park will not be required to purchase any shares of our common stock. If obtaining funding from Lincoln Park were to prove unavailable, we
will need to secure other sources of funding in order to continue with our proposed development activities and launch and commercialize any product candidates for which we
receive  regulatory  approval. Additionally,  even  if  we  are  able  to  sell  all  shares  under  the  Purchase Agreement,  we  will  still  need  additional  capital  to  fully  implement  our
business, operating, and development plans.

Our failure to maintain compliance with Nasdaq’s continued listing requirements could result in the delisting of our common stock.

Our common stock is currently listed on The Nasdaq Capital Market. In order to maintain this listing, we must satisfy minimum financial and other requirements. On August
17, 2020, we received a notice from the Listing Qualifications Department of the Nasdaq informing us that because the closing bid price for our common stock listed on Nasdaq
was below $1.00 per share for 30 consecutive business days, we were not in compliance with the minimum closing bid price requirement for continued listing. We regained
compliance with this requirement on January 21, 2021. However, there can be no assurance that we will be successful in maintaining the listing of our common stock on The
Nasdaq  Capital  Market. Any  perception  among  investors  that  we  are  at  a  heightened  risk  of  delisting  could  negatively  affect  the  market  price  and  trading  volume  of  our
common stock. If our common stock is delisted from Nasdaq, the delisting could: substantially decrease trading in our common stock; adversely affect the market liquidity of
our common stock as a result of the loss of market efficiencies associated with Nasdaq and the loss of federal preemption of state securities laws; adversely affect our ability to
issue additional securities or obtain additional financing in the future on acceptable terms, if at all; result in the potential loss of confidence by investors, suppliers, partners and
employees and fewer business development opportunities; and result in limited news and analyst coverage. Additionally, the market price of our common stock may decline
further, and shareholders may lose some or all of their investment.

We do not anticipate paying any dividends in the foreseeable future.

Our current expectation is that we will retain any future earnings to fund the development and growth of our business. As a result, capital appreciation, if any, of our shares will
be your sole source of gain, if any, for the foreseeable future.

Our ability to use our net operating loss carryforwards and other tax assets to offset future taxable income may be subject to certain limitations.

As  of  December  31,  2020,  we  had  approximately  $420.8  million  of  federal  and  $382.7  million  of  state  net  operating  loss  (“NOL”)  carryforwards  available  to  offset  future
taxable  income,  of  which  $91.8  million  will  carryforward  indefinitely  and  the  remainder  expiring  in  varying  amounts  beginning  in  2021  for  federal  and  state  purposes  if
unused. Utilization of these NOLs depends on many factors, including our future income, which cannot be assured. Under the U.S. Tax Cuts and Jobs Acts (“Tax Act”), U.S.
federal NOLs incurred in 2018 and later years may be carried forward indefinitely, but our ability to utilize such U.S. federal NOLs to offset taxable income is limited to 80% of
the current-year taxable income. It is uncertain if and to what extent various states within the U.S. will conform to the Tax Act. In addition, under Sections 382 and 383 of the
Internal Revenue Code of 1986 and corresponding provisions of state law, if a corporation undergoes an “ownership change” (which is generally defined as a greater than 50
percentage points change (by value) in its equity ownership over a rolling three-year period), the corporation’s ability to use its pre-change NOL carryforwards and other pre-
change tax attributes to offset its post-change income or taxes may be limited. We have not determined whether we have experienced Section 382 ownership changes in the past
and if a portion of our NOLs is therefore subject to an annual limitation under Section 382. Therefore, we cannot provide any assurance that a change in ownership within the
meaning of the Internal Revenue Code of 1986 and corresponding provisions of state law has not occurred in the past, and there is a risk that changes in ownership could have
occurred. We may experience ownership changes as a result of subsequent changes in our stock ownership, as a result of offerings of our stock or subsequent shifts in our stock
ownership, some of which may be outside of our control. In that case, the ability to use net operating loss carryforwards to offset future taxable income will be limited following
any such ownership change and could be eliminated. If eliminated, the related asset would be removed from the deferred tax asset schedule with a corresponding reduction in
the valuation allowance on our financial statements.

Risks Related to Legal, Regulatory, and Compliance Matters

We may never obtain regulatory approval to commercialize any of our product candidates in the U.S., or anywhere else in the world other than Japan, and any products
approved for sale will be subject to continued regulatory review and compliance obligations and there could be further restrictions on post-approval activities, including
commercialization efforts. In obtaining regulatory approval, we will need to negotiate an appropriate product label (aka package insert) with the regulators, which will
determine  the  extent  of  our  allowed  promotional  activities,  and  this  label  could  be  restrictive  or  prohibitory  with  regard  to  subject  matter  we  believe  is  necessary  to
maximize the commercial success of sofpironium bromide.

The  research,  testing,  manufacturing,  safety  surveillance,  efficacy,  quality  assurance  and  control,  recordkeeping,  labeling,  packaging,  storage,  approval,  sale,  marketing,
distribution, import, export, and reporting of safety and other post-market information related to our investigational drug products are subject to extensive regulation by the
FDA and other regulatory authorities in the U.S. and foreign countries, and such regulations differ from country to country and frequently are revised.

Even after we or our partners achieve regulatory approval for a product candidate, if any, we or our partners will be subject to continued regulatory review and compliance
obligations, including on how the product is commercialized. For example, with respect to our product candidates for the U.S., the FDA may impose significant restrictions on
the approved indicated use(s) for which the product may be marketed or on the conditions of approval. A product candidate’s approval may contain requirements for potentially
costly post-approval studies and surveillance, including Phase 4 clinical trials, to monitor the safety and efficacy of the product or include in the approved label restrictions on
the product and how it may be used or sold. We  also  will  be  subject  to  ongoing  FDA  obligations  and  continued  regulatory  review  with  respect  to,  among  other  things,  the
manufacturing, processing, labeling, packaging, distribution, pharmacovigilance and adverse event reporting, storage, advertising, promotion, and recordkeeping for our product
candidates. These requirements include submissions of safety and other post-marketing information and reports, registration, continued compliance with cGMP requirements
and  with  the  FDA’s  GCP  requirements  and  GLP  requirements,  which  are  regulations  and  guidelines  enforced  by  the  FDA  for  all  of  our  product  candidates  in  clinical  and
preclinical development, and for any clinical trials that we conduct post-approval, as well as continued compliance with the FDA’s laws governing commercialization of the
approved product, including but not limited to the FDA’s Office of Prescription Drug Promotion’s regulation of promotional activities and direct-to-consumer advertising, fraud
and abuse, antikickback, product sampling, debarment, scientific speaker engagements and activities, formulary interactions as well as interactions with healthcare practitioners,
including  various  conflict-of-interest  reporting  requirements  for  any  healthcare  practitioners  we  may  use  as  consultants,  and  laws  relating  to  the  pricing  of  drug  products,
including federal “best price” regulations that if not met can prohibit us from participating in federal reimbursement programs like Medicare or Medicaid. To the extent that a
product candidate is approved for sale in other countries, we may be subject

37

Table of Contents

to similar or more onerous (e.g., prohibition on direct-to-consumer advertising and price controls that do not exist in the U.S.) restrictions and requirements imposed by laws and
government regulators, and even private institutions, in those countries.

In addition, manufacturers of drug and biologic products and their facilities are subject to continual review and periodic inspections by the FDA and other regulatory authorities
for compliance with cGMP regulations. If we or a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or
frequency, or problems with the manufacturing, processing, distribution, or storage facility where, or processes by which, the product is made, a regulatory agency may impose
restrictions  on  that  product  or  us,  including  requesting  that  we  initiate  a  product  recall,  or  requiring  notice  to  physicians  or  the  public,  withdrawal  of  the  product  from  the
market, or suspension of manufacturing.

If  we,  our  partners,  our  product  candidates,  or  the  manufacturing  facilities  for  our  product  candidates  fail  to  comply  with  applicable  regulatory  requirements,  a  regulatory
agency may:

•

impose restrictions on the sale, marketing, advertising, or manufacturing of the product, or amend, suspend, or withdraw product approvals, or revoke necessary licenses;

• mandate  modifications  to  or  prohibit  promotional  and  other  product-specific  materials  or  require  us  to  provide  corrective  information  to  healthcare  practitioners  and

other customers and/or patients, or in our advertising and promotion;

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

require  us  or  our  partners  to  enter  into  a  consent  decree,  which  can  include  imposition  of  various  fines,  reimbursements  for  inspection  costs,  required  due  dates  for
specific actions, penalties for noncompliance and, in extreme cases, require an independent compliance monitor to oversee our activities;

issue warning letters, bring enforcement actions, initiate surprise inspections, issue show cause notices or untitled letters describing alleged violations, which may be
publicly available;

commence criminal investigations and prosecutions;

debar certain healthcare professionals;

exclude us from participating in or being eligible for government reimbursement and formulary inclusion;

initiate audits, inspections, accounting and civil investigations, or litigation;

impose injunctions, suspensions, or revocations of necessary approvals or other licenses;

impose other civil or criminal penalties;

suspend or cancel any ongoing clinical trials;

place restrictions on the kind of promotional activities that can be done;

delay or refuse to approve pending applications or supplements to approved applications filed by us or our potential partners;

refuse to permit drugs or precursor chemicals to be imported or exported to or from the U.S.;

suspend or impose restrictions on operations, including costly new manufacturing requirements;

change or restrict our product labeling; or

seize or detain products or require us or our partners to initiate a product recall.

The regulations, policies, or guidance of the FDA, Japan’s PMDA, and other applicable government agencies may change quickly, and new or additional statutes or government
laws or regulations may be enacted, including at federal, state, and

38

Table of Contents

local levels, or case law may issue, which can differ by geography and could prevent or delay regulatory approval of our product candidates or further restrict or regulate post-
approval  activities,  including  commercialization  efforts.  We  cannot  predict  the  likelihood,  nature,  or  extent  of  adverse  government  regulations  that  may  arise  from  future
legislation or administrative action, or judicial outcomes based on litigation, either in the U.S. or abroad. If we are not able to achieve and maintain regulatory or other legal
compliance,  we  may  not  be  permitted  to  commercialize  our  product  candidates,  which  would  adversely  affect  our  ability  to  generate  revenue  and  achieve  or  maintain
profitability.

We have sponsored or supported and may in the future sponsor or support clinical trials for our product candidates outside the U.S. and Japan, and the FDA, PMDA, and
applicable foreign regulatory authorities may not accept data from such trials; in addition, we may not be allowed alone or with local country business partners to obtain
regulatory approval for our product candidates without first conducting clinical trials in each of these other countries.

We have sponsored or supported and may in the future choose to sponsor or support one or more of our clinical trials outside of the U.S. Although the FDA  or  applicable
foreign  regulatory  authorities  may  accept  data  from  clinical  trials  conducted  outside  the  U.S.  or  the  applicable  jurisdiction,  acceptance  of  such  study  data  by  the  FDA  or
applicable  foreign  regulatory  authorities  may  be  subject  to  certain  conditions  or  exclusions.  Where  data  from  foreign  clinical  trials  are  intended  to  serve  as  the  basis  for
marketing approval in the U.S., the FDA will not approve the application on the basis of foreign data alone unless such data are applicable to the U.S. population and U.S.
medical practice; the studies were performed by clinical investigators of recognized competence; and the data are considered valid without the need for an on-site inspection by
the  FDA  or,  if  the  FDA  considers  such  an  inspection  to  be  necessary,  the  FDA  is  able  to  validate  the  data  through  an  on-site  inspection  or  other  appropriate  means.  Many
foreign regulatory bodies have similar requirements. In addition, such foreign studies would be subject to the applicable local laws of the foreign jurisdictions where the studies
are conducted. There can be no assurance the FDA or applicable foreign regulatory authorities will accept data from trials conducted outside of the U.S. or the applicable home
country. If the FDA or applicable foreign regulatory authority does not accept such data, it would likely result in the need for additional clinical trials, which would be costly
and time-consuming and delay aspects of our business plan.

We may face product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is
inadequate.

We face an inherent risk of product liability or similar causes of action as a result of the clinical testing (and use) of our product candidates and will face an even greater risk if
we commercialize any products. This risk exists even if a product is approved for commercial sale by the FDA and is manufactured in facilities licensed and regulated by the
FDA or an applicable foreign regulatory authority and notwithstanding that we comply with applicable laws on promotional activity. Our products and product candidates are
designed to affect important bodily functions and processes. Any side effects, manufacturing defects, misuse, or abuse associated with our product candidates could result in
actual or perceived injury to a patient that may or may not be reversible or potentially even cause death. We cannot offer any assurance that we will not face product liability or
other similar suits in the future or that we will be successful in defending them, nor can we assure that our insurance coverage will be sufficient to cover our liability under any
such cases.

In addition, a liability claim may be brought against us even if our product candidates merely appear to have caused an injury. Product liability claims may be brought against
us by consumers, healthcare providers, pharmaceutical companies, or others selling or otherwise coming  into  contact  with  our  product  candidates,  among  others,  and  under
some circumstances even government agencies. If we cannot successfully defend against product liability or similar claims, we will incur substantial liabilities, reputational
harm, and possibly injunctions and punitive actions. In addition, regardless of merit or eventual outcome, product liability claims may result in:

•

•

•

•

•

withdrawal or delay of recruitment or decreased enrollment rates of clinical trial participants;

termination or increased government regulation of clinical trial sites or entire trial programs;

the inability to commercialize, or restrictions on commercializing, our product candidates;

decreased demand for our product candidates;

impairment of our business reputation;

39

Table of Contents

•

•

•

•

•

•

•

•

product recall or withdrawal from the market or labeling, marketing, or promotional restrictions;

substantial costs of any related litigation or similar disputes;

distraction of management’s attention and other resources from our primary business;

significant delay in product launch;

debarment of our clinical trial investigators or other related healthcare practitioners working with our Company;

substantial monetary awards to patients or other claimants against us that may not be covered by insurance;

withdrawal of reimbursement or formulary inclusion; or

loss of revenue.

We have obtained product liability insurance coverage for our clinical trials. Large judgments have been awarded in class action or individual lawsuits based on drugs that had
unanticipated side effects. Our insurance coverage may not be sufficient to cover all of our product liability-related expenses or losses and may not cover us for any expenses or
losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive, restrictive, and narrow, and, in the future, we may not be able to maintain adequate
insurance coverage at a reasonable cost, or through self-insurance, in sufficient amounts or upon adequate terms to protect us against losses due to product liability or other
similar legal actions. We will need to increase our product liability coverage if any of our product candidates receive regulatory approval, which will be costly, and we may be
unable to obtain this increased product liability insurance on commercially reasonable terms or at all and for all geographies in which we wish to launch. A successful product
liability  claim  or  series  of  claims  brought  against  us  could,  if  judgments  exceed  our  insurance  coverage,  decrease  our  cash,  expose  us  to  liability  and  harm  our  business,
financial condition, operating results, and prospects.

Our employees, independent contractors, principal investigators, other clinical trial staff, consultants, vendors, CROs, and any partners with which we may collaborate may
engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We  are  exposed  to  the  risk  that  our  employees,  officers,  directors,  independent  contractors,  principal  investigators,  other  clinical  trial  staff,  consultants,  advisors,  vendors,
CROs, and any partners with which we may collaborate may engage in fraudulent or other illegal or unethical activity. Misconduct by these persons could include intentional,
reckless, gross or negligent misconduct or unauthorized activity that violates: laws or regulations, including those laws requiring the reporting of true, complete, and accurate
information  to  the  FDA  or  foreign  regulatory  authorities;  product  sampling;  manufacturing  standards;  federal,  state  and  foreign  healthcare  fraud  and  abuse  laws  and  data
privacy; anticorruption laws, anti-kickback and Medicare/Medicaid rules, debarment laws, promotional laws, securities laws, and/or laws that require the true, complete and
accurate reporting of financial information or data, books, and records. If any such or similar actions are instituted against us and we are not successful in defending ourselves or
asserting  our  rights,  those  actions  could  have  a  significant  impact  on  our  business,  including  the  imposition  of  civil,  criminal  and  administrative  and  punitive  penalties,
damages,  monetary  fines,  possible  exclusion  from  participation  in  Medicare,  Medicaid,  and  other  federal  or  state  healthcare  programs,  debarments,  contractual  damages,
reputational harm, diminished profits and future earnings, injunctions, and curtailment or cessation of our operations, any of which could expose us to liability and adversely
affect our business, financial condition, operating results, and prospects.

We may be subject to risks related to pre-approval promotion or off-label use, or unauthorized direct-to-consumer advertising, of our product candidates.

In the U.S., the FDA strictly regulates the advertising and promotion of drug products, and drug products may only be marketed or promoted for their FDA-approved uses,
consistent with the product’s approved labeling and to appropriate patient populations. Advertising and promotion of any product candidate that obtains approval in the U.S. will
be  heavily  scrutinized  by  the  FDA,  the  Department  of  Justice,  the  Office  of  Inspector  General  of  the  Department  of  Health  and  Human  Services,  state  attorneys  general,
members of Congress, the public, and others. Violations, including promotion of our products for unapproved or off-label uses, or inappropriate direct-to-consumer advertising,
are subject to enforcement letters, inquiries and investigations, and civil, criminal, and/or administrative sanctions by the FDA and other government agencies

40

Table of Contents

or tribunals and lawsuits by competitors, healthcare practitioners, consumers, investors, or other plaintiffs. Additionally, advertising and promotion of any product candidate that
obtains approval outside of the U.S. will be heavily scrutinized by relevant foreign regulatory authorities.

Even if we obtain regulatory approval for our product candidates, the FDA or comparable foreign regulatory authorities may require labeling changes or impose significant
restrictions on a product’s indicated uses or marketing, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance.

In the U.S., engaging in impermissible promotion of our product candidates for off-label uses, or engaging in pre-approval promotion of an unapproved drug candidate, also can
subject  us  to  false  claims  litigation  under  federal  and  state  statutes,  which  can  lead  to  civil,  criminal  and/or  administrative  penalties  and  fines  and  agreements,  such  as  a
corporate integrity agreement, that materially restrict the manner in which we promote or distribute our product candidates. If we do not lawfully promote our products once
they have received regulatory approval, we may become subject to such litigation and, if we are not successful in defending against such actions, those actions could expose us
to liability and could have a material adverse effect on our business, financial condition, operating results, and prospects and even result in having an independent compliance
monitor assigned to audit our ongoing operations at our cost for a lengthy period of time.

Healthcare reform measures, including price controls or restricted access, could hinder or prevent the commercial success of our product candidates.

A new presidential administration just took office. The enactment of any new healthcare initiatives or pharmaceutical industry regulations could have significant impacts on our
ability to advance development of sofpironium bromide or other product candidates and eventually to commercialize them, if at all. In particular, the current President and Vice
President during their successful campaign proposed to lower Medicare Part B drug prices, in addition to contemplating other measures to lower or prescribe certain mandatory
prescription drug prices or drug substitution policies. While these proposals have not yet been enacted, we expect that additional state and federal healthcare reform measures
will  be  adopted  in  the  future,  any  of  which  could  limit  the  amounts  that  federal  and  state  governments  will  pay  for  healthcare  products  and  services,  which  could  result  in
reduced demand for our product candidates if approved or additional pricing pressures.

There are also calls to severely curtail or ban all direct-to-consumer advertising of pharmaceuticals or restrict activities by pharmaceutical sales representatives to have access to
prescribers, which would limit our ability to market our product candidates. With regard to marketing directly to consumers and patients, the U.S. is in a minority of jurisdictions
that even allow this kind of advertising, and its removal could limit the potential reach of a marketing campaign.

We also may be subject to stricter healthcare laws, regulation, and enforcement, and our failure to comply with those laws could expose us to liability or adversely affect
our business, financial condition, operating results, and prospects.

Certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights and privacy are and will be applicable to our business. We are subject
to regulation by both the federal government and the states in which we or our partners conduct business. The healthcare laws and regulations that may affect our ability to
operate include: the Federal Food, Drug and Cosmetic Act, as amended; Title 21 of the Code of Federal Regulations Part 202 (21 CFR Part 202); the 21  Century Cures Act, the
federal Anti-Kickback Statute; federal civil and criminal false claims laws and civil monetary penalty laws; the federal Health Insurance Portability and Accountability Act of
1996, as amended by the Health Information Technology for Economic and Clinical Health Act; the Prescription Drug Marketing Act (for sampling of drug product); the federal
Best Price Act and Medicaid drug rebate program; the federal physician sunshine reporting requirements under the Affordable Care Act and state disclosure laws; the Foreign
Corrupt Practices Act as it applies to activities both inside and outside of the U.S.; the federal Right-to-Try legislation; and state law equivalents of many of the above federal
laws.

st

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject
to challenge under one or more of such laws. In addition, recent healthcare reform legislation has strengthened these laws. For example, the Affordable Care Act, among other
things, amended the intent requirement of the federal Anti-Kickback Statute and certain criminal healthcare fraud statutes. A person or entity no longer needs to have actual
knowledge of the statute or specific intent to violate it. In addition, the Affordable Care Act provides that 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 federal civil False Claims Act.

41

Table of Contents

Achieving and sustaining compliance with these laws may prove costly. In addition, any action against us for violation of these laws, even if we successfully defend against it,
could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business and result in reputational damage. If our operations
are  found  to  be  in  violation  of  any  of  the  laws  described  above  or  any  other  governmental  laws  or  regulations  that  apply  to  us,  we  may  be  subject  to  penalties,  including
administrative,  civil,  and  criminal  penalties,  damages,  including  punitive  damages,  fines,  disgorgement,  the  exclusion  from  participation  in  federal  and  state  healthcare
programs, individual imprisonment or corporate criminal liability, or the curtailment or restructuring of our operations, and injunctions, any of which could expose us to liability
and could adversely affect our business, financial condition, operating results, and prospects.

We incur costs and demands upon management as a result of complying with the laws and regulations affecting public companies.

We  incur  significant  legal,  accounting,  and  other  expenses  that  Private  Brickell  did  not  incur  as  a  private  company  prior  to  the  Merger  and  operating  as  a  public  company,
including  costs  associated  with  public  company  reporting  and  other  SEC  requirements.  We  also  incur  costs  associated  with  corporate  governance  requirements,  including
requirements under the Sarbanes-Oxley Act, as well as rules implemented by the SEC and The Nasdaq Stock Market LLC (“Nasdaq”). These rules and regulations have, and
are expected to continue to, increase our legal and financial compliance costs and to make some activities more time-consuming and costly. These rules and regulations may
also make it expensive for us to operate our business.

Risks Related to Strategic Matters

We  intend  to  in-license  and  acquire  product  candidates  and  may  engage  in  other  strategic  transactions,  which  could  impact  our  liquidity,  increase  our  expenses,  and
present significant distractions to our management.

One of our strategies is to in-license and acquire product candidates, and we may engage in other strategic transactions. Additional potential transactions that we may consider
include  a  variety  of  different  business  arrangements,  including  mergers  and  acquisitions,  spin-offs,  strategic  partnerships,  joint  ventures,  co-marketing,  co-promotion,
distributorships,  development  and  co-development,  royalty  monetization,  restructurings,  divestitures,  business  combinations,  and  investments  on  a  global  basis. Any  such
transaction(s) may require us to incur non-recurring or other charges, may increase our near- and long-term expenditures, and may cause us to grow and expand rapidly, putting
pressure  on  current  resources  and  capabilities,  and  may  pose  significant  integration  challenges  or  disrupt  our  management  or  business,  which  could  adversely  affect  our
operations and financial results. Further, any such transaction(s) may require us to obtain additional financing, which may not be available to us on favorable terms or at all.
Accordingly, there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, and any transaction that we do complete
could  expose  us  to  liability,  delays,  and  implementation  obstacles  that  could  harm  our  business,  financial  condition,  operating  results,  and  prospects.  We  have  no  current
commitment or obligation to enter into any transaction described above other than ones to which we are already committed.

Our failure to in-license, acquire, develop, and market successfully additional product candidates or approved products would impair our ability to grow our business.

We intend to in-license, acquire, develop, and market additional products and product candidates. Because our internal research and development capabilities are limited, we
may be dependent on pharmaceutical or other companies, investment groups or funds, academic or government scientists and other researchers to sell or license products or
technology to us. The success of this strategy depends partly on our ability to identify and select promising pharmaceutical product candidates and products, negotiate licensing
or acquisition agreements with their current owners, and finance these arrangements.

The  process  of  proposing,  negotiating,  and  implementing  a  license  or  acquisition  of  a  product  candidate  or  approved  product  is  lengthy  and  complex.  Other  companies,
including some with substantially greater financial, marketing, sales, legal and other resources, may compete with us for the license or acquisition of product candidates and
approved products. We have limited resources to identify and execute the acquisition or in-licensing of third-party products, businesses, and technologies and integrate them into
our  current  infrastructure.  Moreover,  we  may  devote  resources  to  potential  acquisitions  or  licensing  opportunities  that  are  never  completed,  or  we  may  fail  to  realize  the
anticipated benefits of such efforts. We may not be able to acquire the rights to additional product candidates on terms that we find acceptable or at all.

42

Table of Contents

Further, any product candidate that we acquire may require additional development efforts prior to commercial sale, including preclinical or clinical testing and approval by the
FDA and applicable foreign regulatory authorities for the targeted use(s), or present with significant integration issues. All product candidates are prone to significant risks of
failure typical of pharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by
regulatory authorities. In addition, we cannot provide assurance that any approved products that we acquire will be manufactured or sold profitably, obtain reimbursement, be
subject  to  patents  and  other  intellectual  property  rights  that  provide  any  form  of  market  or  regulatory  exclusivity,  sustain  historical  levels  of  performance  that  made  the
acquisition initially attractive, or achieve/maintain market acceptance.

Other than sofpironium bromide, our other product candidates are at the early stages of clinical and regulatory development.

We are evaluating the next clinical development steps for various early-stage clinical product candidates (prior to Phase 3). The regulatory approval processes of the FDA and
comparable  foreign  authorities  are  lengthy,  time  consuming,  costly,  and  inherently  unpredictable,  especially  for  early-stage  product  candidates.  The  time  required  to  obtain
approval for early-stage product candidates from the FDA and comparable foreign authorities is unpredictable but typically takes many years, involves significant expenditures,
and  depends  upon  numerous  factors,  including  the  substantial  discretion  of  the  regulatory  authorities.  In  addition,  approval  policies,  regulations,  or  the  type  and  amount  of
clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. Our early-stage product
candidates will require substantial additional preclinical and clinical development before we will be able to submit an application to the FDA, if at all. Accordingly, we cannot
provide assurance that we will be able to seek or obtain regulatory approval for any of our early-stage product candidates.

We may choose not to continue developing or commercializing any of our early-stage product candidates, or to pursue the AnGes collaboration regarding a COVID-19
vaccine, at any time during development or after approval, which would reduce or eliminate our potential return on investment for those product candidates.

At any time, we may decide to discontinue the development of any of our early-stage or licensed rights to product candidates for a variety of reasons, including the appearance
of  new  technologies  that  make  our  product  obsolete  or  significantly  impact  the  ability  to  commercialize  the  affected  product  successfully,  competition  from  a  competing
product including entry of generics, supply chain considerations, intellectual property right impacts, ability to price or changes in or failure to comply with applicable regulatory
requirements, or constraints on obtaining additional financing and capital. If we terminate or exit a program in which we have invested significant resources, we will not receive
any return on our investment, and we will have missed the opportunity to have allocated those resources to potentially more productive uses.

Risks Related to Our Dependence on Third Parties

We expect to rely on our collaboration with third-party out-license partners for the successful development and commercialization of our product candidates.

We expect to rely upon the efforts of third-party out-license partners for the successful development and commercialization of our current and future product candidates. The
clinical and commercial success of our product candidates may depend upon maintaining successful relationships with third-party out-license partners which are subject to a
number of significant risks, including the following:

•

•

•

our partners’ ability to execute their responsibilities in a timely, cost-efficient, and compliant manner;

reduced control over supply, delivery, and manufacturing schedules;

price increases and product reliability;

• manufacturing deviations from internal or regulatory specifications;

•

• misappropriation of our current or future product candidates; and

•

other risks in potentially meeting our current and future product commercialization schedule or satisfying the requirements of our end-users.

We  cannot  assure  you  that  we  will  be  able  to  establish  or  maintain  third-party  out-license  partner  relationships  to  successfully  develop  and  commercialize  our  product
candidates.

We  rely  completely  on  third-party  contractors  to  supply,  manufacture,  and  distribute  clinical  drug  supplies  for  our  product  candidates,  including  certain  sole-source
suppliers and manufacturers; we intend to rely on third parties for commercial supply, manufacturing, and distribution if any of our product candidates receive regulatory
approval;  and  we  expect  to  rely  on  third  parties  for  supply,  manufacturing,  and  distribution  of  preclinical,  clinical,  and  commercial  supplies  of  any  future  product
candidates.

We do not  currently  have,  nor  do  we  plan  to  acquire,  the  infrastructure  or  internal  capability  to  supply,  store,  manufacture,  or  distribute  preclinical,  clinical,  or  commercial
quantities of drug substances or products. Additionally, we have not entered into a long-term commercial supply agreement to provide us with such drug substances or products.
As a result, our ability to develop our product candidates is dependent, and our ability to supply our products commercially will depend, in part, on our ability to obtain the APIs
and other substances and materials used in our product candidates successfully from third parties and to have finished products manufactured by third parties in accordance with
regulatory  requirements  and  in  sufficient  quantities  for  preclinical  and  clinical  testing  and  commercialization.  If  we  fail  to  develop  and  maintain  supply  and  other  technical
relationships with these third parties, or global conditions like the coronavirus outbreak significantly and adversely impact such third parties, we may be unable to continue to
develop or commercialize our products and product candidates.

We do not have direct control over whether our contract suppliers and manufacturers will maintain current pricing terms, be willing to continue supplying us with APIs and
finished products, or maintain adequate capacity and capabilities to serve our needs, including quality control, quality assurance, and qualified personnel. We are dependent on
our contract suppliers and manufacturers for day-to-day compliance with applicable laws and cGMPs for production of both APIs and finished products. If the safety or quality
of any product or product candidate or component is compromised due to a failure to adhere to applicable laws or for other reasons, we may not be able to commercialize or
obtain regulatory approval for the affected product or product candidate successfully, and we may be held liable for injuries sustained as a result.

In order to conduct larger or late-stage clinical trials for our product candidates and supply sufficient commercial quantities of the resulting drug product and its components, if
that product candidate is approved for sale, our contract manufacturers and suppliers will need to produce our drug substances and product candidates in larger quantities, more
cost-effectively and, in certain cases, at higher yields than they currently achieve. If our third-party contractors are unable to scale up the manufacture of any of our product
candidates successfully in sufficient quality and quantity and at commercially reasonable prices, or are shut down or put on clinical hold by government regulators, and we are
unable to find one or more replacement suppliers or manufacturers capable of production at a substantially equivalent cost in substantially equivalent volumes and quality, and
we are unable to transfer the processes successfully on a timely basis, the development of that product candidate and regulatory approval or commercial launch for any resulting
products may be delayed, or there may be a shortage in supply, either of which could significantly harm our business, financial condition, operating results, and prospects.

We  expect  to  continue  to  depend  on  third-party  contract  suppliers  and  manufacturers  for  the  foreseeable  future.  Our  supply  and  manufacturing  agreements,  if  any,  do  not
guarantee that a contract supplier or manufacturer will provide services adequate for our needs. Additionally, any damage to or destruction of our third-party manufacturers’ or
suppliers’ facilities or equipment, even by force majeure, may significantly impair our ability to have our products and product candidates manufactured on a timely basis. Our
reliance  on  contract  manufacturers  and  suppliers  further  exposes  us  to  the  possibility  that  they,  or  third  parties  with  access  to  their  facilities,  will  have  access  to  and  may
misappropriate our trade secrets or other proprietary information. In addition, the manufacturing facilities of certain of our suppliers may be located outside of the U.S. This
may give rise to difficulties in importing our products or product candidates or their components into the U.S. or other countries.

Manufacturing  and  supply  of  the  APIs  and  other  substances  and  materials  used  in  our  product  candidates  and  finished  drug  products  is  a  complex  and  technically
challenging undertaking, and there is potential for failure at many points in the manufacturing, testing, quality control and assurance and distribution supply chain, as
well as the potential for latent defects after products have been manufactured and distributed.

44

Table of Contents

Manufacturing and supply of APIs, other substances and materials, and finished drug products is technically challenging. Changes beyond our direct control can impact the
quality,  volume,  price,  and  successful  delivery  of  our  products  and  product  candidates  and  can  impede,  delay,  limit  or  prevent  the  successful  development  and
commercialization of our products and product candidates. Mistakes and mishandling, and/or disruptions in the supply chain, are not uncommon despite reasonable best efforts
and can affect successful production and supply. Some of these risks include but are not limited to:

•

•

•

•

•

•

•

•

failure of our manufacturers to follow cGMP or other legal requirements or mishandling of or adulterating product while in production or in preparation for transit;

inability of our contract suppliers and manufacturers to efficiently and cost-effectively increase and maintain high yields and batch quality, consistency, and stability;

difficulty in establishing optimal drug delivery substances and techniques, production and storage methods, and packaging and shipment processes;

challenges in designing effective drug delivery substances and techniques especially in light of competitor options;

transportation and import/export risk, particularly given the global nature of our supply chain;

delays in analytical results or failure of analytical techniques that we depend on for quality control/assurance and release of a product;

natural  disasters,  strikes  and  labor  disputes,  epidemics  or  pandemics,  war  and  terrorism,  financial  distress,  lack  of  raw  material  supply,  issues  with  facilities  and
equipment or other forms of disruption to business operations of our contract manufacturers and suppliers; and

latent defects that may become apparent after a product has been released and even sold and used and that may result in recall and destruction of the product.

Any  of  these  factors  could  result  in  delays  or  higher  costs  in  connection  with  our  clinical  trials,  regulatory  submissions,  required  approvals,  or  commercialization  of  our
products, which could expose us to liability or harm our business, financial condition, operating results, and prospects.

Risks Related to Our Intellectual Property

We may not be able to obtain, maintain or enforce global patent rights or other intellectual property rights that cover sofpironium bromide and related technologies (and
any other product candidates) that are of sufficient breadth and term.

Our  success  with  respect  to  sofpironium  bromide  will  depend,  in  part,  on  our  ability  to  protect  patent  and  other  intellectual  property  protections  in  both  the  U.S.  and  other
countries,  to  preserve  our  trade  secrets,  and  to  prevent  third  parties  from  infringing  on  our  proprietary  rights.  Our  ability  to  prevent  unauthorized  or  infringing  use  of
sofpironium bromide by third parties depends in substantial part on our ability to leverage valid and enforceable patents and other intellectual property rights around the world.

The patent application process, also known as patent prosecution, is expensive and time-consuming, and we and our current or future licensors and licensees may not be able to
prepare, file, and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner in all the countries that may be desirable. It is also possible
that we or our current licensors and licensees, or any future licensors or licensees, will fail to identify patentable aspects of inventions made in the course of development and
commercialization activities before it is too late to obtain patent protection by others on them. Therefore, these and any of our patents and applications may not be prosecuted
and enforced in a manner consistent with the best interests of our business. Moreover, our competitors independently may develop equivalent knowledge, methods, and know-
how or discover workarounds to our patents that would not constitute infringement. Our partners or licensees may inappropriately take or use our intellectual property and/or
confidential  information  to  infringe  our  patents  or  otherwise  violate  their  contractual  obligations  as  to  us  related  to  protection  of  our  intellectual  property. Any  of  these
outcomes could impair our ability to enforce the exclusivity of our patents effectively, which may have an adverse impact on our business, financial condition, operating results,
and prospects.

45

Table of Contents

Due to constantly shifting global legal standards relating to patentability, validity, enforceability, and claim scope of patents covering pharmaceutical inventions, our ability to
protect patents in any jurisdiction is uncertain and involves complex legal and factual questions, especially across countries. Accordingly, rights under any applicable patents
that apply to us may not cover our product candidates or may not provide us with sufficient protection for our product candidates to afford a sustainable commercial advantage
against competitive products or processes, including those from branded, generic, and OTC pharmaceutical companies. In addition, we cannot guarantee that any patents or
other intellectual property rights will issue from any pending or future patent or other similar applications related to us. Even if patents or other intellectual property rights have
issued or will issue, we cannot guarantee that the claims of these patents and other rights are or will be held valid or enforceable by the courts or other legal authorities, through
injunction  or  otherwise,  or  will  provide  us  with  any  significant  protection  against  competitive  products  or  otherwise  be  commercially  valuable  to  us  in  every  country  of
commercial significance that we may target, or that a legislative or executive branch of government may alter the rights and enforceability thereof at any time.

Competitors in the field of dermatologic therapeutics have created a substantial amount of prior art, including scientific publications, abstracts, posters, presentations, patents
and patent applications, and other public disclosures including on the Internet and various social media. Our ability to protect valid and enforceable patents and other intellectual
property rights depends on whether the differences between our proprietary technology and the prior art allow our technology to be patentable over the prior art. We do not
have outstanding issued patents covering all of the recent developments in our technology and are unsure of the patent protection that we will be successful in securing, if any.
Even if the patents do issue successfully, third parties may design around or challenge the validity, enforceability, or scope of such issued patents or any other issued patents or
intellectual property that apply to us, which may result in such patents and/or other intellectual property being narrowed, invalidated, or held unenforceable. If the breadth or
strength of protection provided by the patents and other intellectual property we hold or pursue with respect to our product candidates is challenged, regardless of our future
success, it could dissuade companies from collaborating with us to develop, or threaten our ability to commercialize or finance, our product candidates.

The  laws  of  some  foreign  jurisdictions  do  not  provide  intellectual  property  rights  to  the  same  extent  or  duration  as  in  the  U.S.,  and  many  companies  have  encountered
significant  difficulties  in  acquiring,  maintaining,  protecting,  defending,  and  especially  enforcing  such  rights  in  foreign  jurisdictions.  If  we  encounter  such  difficulties  in
protecting,  or  are  otherwise  precluded  from  effectively  protecting,  our  intellectual  property  in  foreign  jurisdictions,  our  business  prospects  could  be  substantially  harmed,
especially internationally.

Patents have a limited lifespan. In the U.S., the natural expiration of a patent is generally 20 years after it is filed, with patent term extensions granted in certain instances to
compensate for part of the period in which the drug was under development and could not be commercialized while under the patent. Without patent protection for sofpironium
bromide, we may be open to competition from generic versions of sofpironium bromide. The issued U.S. patents relating to sofpironium bromide run through 2031, including
expected extensions just described. Other patent rights we are seeking in the U.S. would provide expected coverage through 2040, but only in the event of a grant of such rights.

Proprietary trade secrets and unpatented know-how and confidential information are also important to our business. Although we have taken steps to protect our trade secrets,
unpatented  know-how,  and  confidential  information  by  entering  into  confidentiality  and  nondisclosure  agreements  with  third  parties  and  intellectual  property  protection
agreements with officers, directors, employees, and certain consultants and advisors, there can be no assurance that binding agreements will not be breached or enforced by
courts  or  other  legal  authorities,  that  we  would  have  adequate  remedies  for  any  breach,  including  injunctive  and  other  equitable  relief,  or  that  our  trade  secrets,  unpatented
know-how, and confidential information will not otherwise become known, be inadvertently disclosed by us or our agents and representatives, or be independently discovered
by our competitors. If trade secrets are independently discovered, we would not be able to prevent their use, and if we and our agents or representatives inadvertently disclose
trade secrets, unpatented know-how, and/or confidential information, we may not be allowed to retrieve the inadvertently disclosed trade secret, unpatented know-how, and/or
confidential information and maintain the exclusivity we previously enjoyed.

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

Filing, prosecuting, and defending patents on our product candidates does not guarantee exclusivity. The requirements for patentability differ in certain countries, particularly
developing countries, and can change over time in the same country. In addition, the laws of some other countries do not protect intellectual property rights to the same extent as
laws in the U.S., especially when it comes to granting use and other kinds of patents and what kind of enforcement rights will be allowed,

46

Table of Contents

especially injunctive relief in a civil infringement proceeding. Consequently, we may not be able to prevent third parties from practicing our inventions in countries outside the
U.S. and even in launching an identical version of our product notwithstanding us having a valid patent or other intellectual property rights in that country. Competitors may
use our technologies in jurisdictions where we or our licensors have not obtained patent or other protections to develop their own products, or produce copy products, and,
further, may export otherwise infringing products to territories where we have patent and other protections but enforcement against infringing activities is inadequate or where
we have no patents or other intellectual property rights. These products may compete with our products, and our patents or other intellectual property rights may not be effective
or sufficient to prevent them from commercialization or other uses.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries,
particularly in developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to pharmaceuticals, and the
judicial  and  government  systems  are  often  corrupt,  apathetic,  or  ineffective,  which  could  make  it  difficult  for  us  to  stop  the  infringement  of  our  patents  or  marketing  of
competing  products  in  violation  of  our  intellectual  property  rights  generally.  Proceedings  to  enforce  our  intellectual  property  rights  in  foreign  jurisdictions  could  result  in
substantial costs and divert our efforts and attention from other aspects of our business, could put our global patents and other rights at risk of being invalidated or interpreted
narrowly and our global patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuit that we initiate
or infringement action brought against us, and the damages or other remedies awarded, if any, may not be commercially meaningful when we are the plaintiff. When we are the
defendant, we may be required to post large bonds to stay in the market while we defend ourselves from an infringement action.

In addition, certain countries in Europe and certain developing countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to
third parties, especially if the patent owner does not enforce or use its patents over a protracted period of time. In some cases, the courts will force compulsory licenses on the
patent holder even when finding the patentholder’s patents are valid if the court believes it is in the best interests of the country to have widespread access to an essential product
covered  by  the  patent.  Further,  there  is  no  guarantee  that  any  country  will  not  adopt  or  impose  compulsory  licensing  in  the  future.  In  these  situations,  the  royalty  the  court
requires  to  be  paid  by  the  licenseholder  receiving  the  compulsory  license  may  not  be  calculated  at  fair  market  value  and  can  be  inconsequential,  thereby  disaffecting  the
patentholder’s business. In these countries, we may have limited remedies if our patents are infringed or if we are compelled to grant a license to our patents to a third party,
which  could  also  materially  diminish  the  value  of  those  patents.  This  would  limit  our  potential  revenue  opportunities. 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  own  or  license,  especially  in
comparison  to  what  we  enjoy  from  enforcing  our  intellectual  property  rights  in  the  U.S.  Finally,  our  ability  to  protect  and  enforce  our  intellectual  property  rights  may  be
adversely  affected  by  unforeseen  changes  in  both  U.S.  and  foreign  intellectual  property  laws,  or  changes  to  the  policies  in  various  government  agencies  in  these  countries,
including but not limited to the patent office issuing patents and the health agency issuing pharmaceutical product approvals. For example, in Brazil, pharmaceutical patents
require  prior  initial  approval  of  the  Brazilian  health  agency, ANVISA.  Finally,  many  countries  have  large  backlogs  in  patent  prosecution,  and  in  some  countries  in  Latin
America, it can take years, even decades, just to get a pharmaceutical patent application reviewed notwithstanding the merits of the application.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by
governmental patent and similar agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.

Periodic maintenance and annuity fees on any issued patent are due to be paid to the U.S. Patent and Trademark Office (“USPTO”) and foreign patent agencies in several stages
over the lifetime of a patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment, and
other similar provisions during the patent application process. While an inadvertent lapse can, in many cases, be cured by payment of a late fee or by other means in accordance
with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss
of patent rights in the relevant jurisdiction just for failure to know about and/or timely pay such fee. Noncompliance events that could result in abandonment or lapse of a patent
or patent application include failure to respond to official actions within prescribed time limits, non-payment of fees in prescribed time periods, and failure to properly legalize
and  submit  formal  documents  in  the  format  and  style  the  country  requires.  If  we  or  our  licensors  fail  to  maintain  the  patents  and  patent  applications  covering  our  product
candidates for any  reason,  our  competitors  might  be  able  to  otherwise  enter  the  market,  which  would  have  an  adverse  effect  on  our  business,  financial  condition,  operating
results, and prospects.

47

Table of Contents

In  addition,  countries  continue  to  increase  the  fees  that  are  charged  to  acquire,  maintain,  and  enforce  patents  and  other  intellectual  property  rights,  which  may  become
prohibitive to initiate or continue paying in certain circumstances.

If we fail to comply with our obligations under our intellectual property license agreements, we could lose license rights that are important to our business. Additionally,
these agreements may be subject to disagreement over contract interpretation, which could narrow the scope of our rights to the relevant intellectual property or technology
or increase our financial or other obligations to our licensors.

We  have  entered  into  in-license  arrangements  with  respect  to  certain  of  our  product  candidates.  These  license  agreements  impose  various  diligence,  milestone,  royalty,
insurance, reporting, and other obligations on us. If we fail to comply with these obligations, the respective licensors may have the right to terminate or modify the license, or
trigger other more disadvantageous contract clauses, in which event we may not be able to finance, develop or market the affected product candidate. The loss of such rights
could expose us to liability and could materially adversely affect our business, financial condition, operating results, and prospects.

Our commercial success depends on our ability to develop, manufacture, market, and sell our product candidates and use our proprietary technologies without infringing the
proprietary rights of third parties and do this in one or more countries. We cannot assure that marketing and selling such product candidates and using such technologies will not
infringe existing or future patents or other intellectual property rights. Numerous U.S. and foreign-issued patents and pending patent applications owned by third parties exist in
the fields relating to our product candidates. As the biotechnology and pharmaceutical industries expand and more patents and other intellectual property rights are issued, the
risk  increases  that  others  may  assert  that  our  product  candidates,  technologies,  or  methods  of  delivery  or  use(s)  infringe  their  patent  or  other  intellectual  property  rights.
Moreover, it is not always clear to industry participants, including us, which patents and other intellectual property rights cover various drugs, biologics, drug delivery systems
and formulations, manufacturing processes, or their methods of use, and which of these patents may be valid and enforceable. Thus, because of the large number of patents
issued and patent applications filed in our fields across many countries, there may be a risk that third parties may allege they have patent or other rights encompassing our
product candidates, technologies, or methods.

In addition, there may be issued patents of third parties that are infringed or are alleged to be infringed by our product candidates or proprietary technologies notwithstanding
the  patents  we  may  possess.  Because  some  patent  applications  in  the  U.S.  and  other  countries  may  be  maintained  in  confidence  until  the  patents  are  issued,  because  patent
applications in the U.S. and many foreign jurisdictions are typically not published until eighteen (18) months or some other time after filing, and because publications in the
scientific literature or other public disclosures often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by
our patents or our pending applications. Our competitors may have filed, and may in the future file, patent applications covering our product candidates or technology similar to
our technology. Any such patent application may have priority over our patent applications or patents, which could further require us to obtain rights to issued patents covering
such technologies, which may mean paying significant licensing fees or royalties, or the like. If another party has filed a U.S. patent application on inventions similar to ours, we
or the licensor, may have to participate in the U.S. in an interference proceeding to determine priority of invention.

We may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights alleging that our product candidates or proprietary
technologies infringe such third parties’ intellectual property rights, including litigation resulting from filing in the U.S. under Paragraph IV of the Hatch-Waxman Act or other
countries’ laws similar to the Hatch-Waxman Act. These lawsuits could claim that there are existing patent rights for such drug, and this type of litigation can be costly and
could adversely affect our operating results and divert the attention of managerial and technical personnel, even if we do not infringe such patents or the patents asserted against
us are ultimately established as invalid. There is a risk that a court or other legal authority would decide that we are infringing the third party’s patents and would order us to
stop the activities covered by the patents. In addition, there is a risk that a court or other legal authority will order us to pay the other party significant damages for having
violated the other party’s patents or intellectual property rights.

Because we rely on certain third-party licensors, licensees, and partners and will continue to do so in the future, around the world, if one of our licensors, licensees, or partners is
sued for infringing a third party’s intellectual property rights, this could expose us to liability, and our business, financial condition, operating results, and prospects could suffer
in the same manner as if we were sued directly. In addition to facing litigation risks, we have agreed to indemnify certain third-party licensors, licensees, and partners against
claims  of  infringement  caused  by  our  proprietary  technologies,  and  we  have  entered  or  may  enter  into  cost-sharing  agreements  with  some  of  our  licensors,  licensees,  and
partners that could require us to pay some of the costs of patent or other intellectual property rights litigation brought against those third parties whether or not the alleged

48

Table of Contents

infringement  is  caused  by  our  proprietary  technologies.  In  certain  instances,  these  cost-sharing  agreements  could  also  require  us  to  assume  greater  responsibility  for
infringement damages than would be assumed just on the basis of our technology.

The occurrence of any of the foregoing could expose us to liability or adversely affect our business, financial condition, operating results, and prospects at any time.

We may be subject to claims that our employees, officers, directors, advisors, consultants, or independent contractors have wrongfully used or disclosed to us alleged trade
secrets or other confidential and proprietary information of their former employers or their former or current partners or customers.

As  is  common  in  the  biotechnology  and  pharmaceutical  industries,  certain  of  our  employees,  officers,  and  directors  were  formerly  employed  by  other  biotechnology  or
pharmaceutical companies, including our competitors or potential competitors. Moreover, we engage the services of advisors, consultants, and independent contractors to assist
us in the development of our products and product candidates, many of whom were previously employed at, or may have previously been or are currently providing consulting
services to, other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees, officers,
directors, advisors, consultants, and independent contractors or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary confidential information
of their former employers or their former or current customers. Although we have no knowledge of any such claims being alleged to date, if such claims were to arise, litigation
may be necessary to defend against any such claims. Even if we are successful in defending against any such claims, any litigation like this could be protracted, expensive, a
distraction to our management team, and/or board of directors, not viewed favorably by investors and other third parties, and may potentially result in an unfavorable outcome.

General Risk Factors

Provisions of Delaware law and our restated certificate of incorporation and amended and restated bylaws may discourage another company from acquiring us and may
prevent attempts by our stockholders to replace or remove our current management.

Provisions of Delaware law and our restated certificate of incorporation and amended and restated bylaws may discourage, delay, or prevent a merger or acquisition that our
stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. In addition, these provisions may frustrate or
prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace or remove our board of directors.
These provisions include, but are not limited to:

•

•

•

•

•

authorizing the issuance of “blank check” preferred stock without any need for action by stockholders;

providing for a classified board of directors with staggered terms;

requiring supermajority stockholder voting to effect certain amendments to our current certificate of incorporation and bylaws;

eliminating the ability of stockholders to call special meetings of stockholders; and

establishing  advance  notice  requirements  for  nominations  for  election  to  our  board  of  directors  or  for  proposing  matters  that  can  be  acted  on  by  stockholders  at
stockholder meetings.

Although we believe these provisions collectively provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they
would apply even if an offer may be considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to
replace  or  remove  our  current  management  by  making  it  difficult  for  stockholders  to  replace  members  of  our  board  of  directors,  which  is  responsible  for  appointing  the
members of our management.

If we fail to attract and retain management and other key personnel and directors, we may be unable to continue to successfully develop or commercialize our product
candidates or otherwise implement our business plan.

49

Table of Contents

Our ability to compete in the highly competitive pharmaceuticals industry depends on our ability to attract and retain highly qualified managerial, scientific, medical, legal, sales
and marketing and other personnel, and directors of our board of directors. We are highly dependent on our management, scientific personnel, and our directors. In addition, as
a development stage company, we are heavily reliant on equity awards to compensate our management, other personnel and directors, and we will be significantly limited in our
ability to grant equity awards unless and until the number of authorized shares of our common stock and the number of shares of our common stock available for issuance
pursuant to the 2020 Omnibus Long-Term Incentive Plan are increased, each of which would require stockholder approval. The loss of the services of any of these individuals
could impede, delay, or prevent the successful development of our product pipeline, completion of our planned clinical trials, commercialization of our product candidates or in-
licensing or acquisition of new assets and could impact negatively our ability to implement successfully our business plan and in a way that complies with all applicable laws. If
we lose the services of any of these individuals, we might not be able to find suitable replacements on a timely basis or at all, and our business could be harmed as a result. We
might not be able to attract or retain qualified management and other key personnel or directors in the future due to the intense competition for qualified individuals among
biotechnology, pharmaceutical, and other businesses.

On August 31, 2019, Vical and Private Brickell completed the Merger. In accordance with the Merger, Merger Sub merged with and into Private Brickell, with Private Brickell
surviving  as  a  wholly-owned  subsidiary  of  Vical.  On  August  31,  2019,  immediately  after  the  completion  of  the  Merger,  the  Company  changed  its  name  from  “Vical
Incorporated”  to  “Brickell  Biotech,  Inc.”  and  Private  Brickell  changed  its  name  from  “Brickell  Biotech,  Inc.”  to  “Brickell  Subsidiary,  Inc.”  Subsequent  to  the  Merger,  our
common stock is traded on The Nasdaq Capital Market under the symbol “BBI.”

Holders

As  of  March  5,  2021,  we  had  196  registered  holders  of  record  of  our  common  stock. A  substantially  greater  number  of  holders  of  our  common  stock  are  “street  name”  or
beneficial holders, whose shares of record are held by banks, brokers, other financial institutions, and registered clearing agencies. 

Stock Repurchases

There were no repurchases made by us or on our behalf, or by any “affiliated purchaser,” of shares of our common stock during the year ended December 31, 2020.

Dividend Policy

We historically have not, and do not anticipate in the future, paying dividends on our common stock. We currently intend to retain all of our future earnings, if any, to finance
the  growth  and  development  of  our  business.  We  are  not  subject  to  any  legal  restrictions  respecting  the  payment  of  dividends,  except  that  we  may  not  pay  dividends  if  the
payment would render us insolvent. Subject to these limitations, any future determination as to the payment of cash dividends on our common stock will be at our board of
directors’ discretion and will depend on our financial condition, operating results, capital requirements, and other factors that our board of directors considers to be relevant.

Recent Sales of Unregistered Securities

In connection with the enrollment of the first patient in our Cardigan I Study in the U.S., on October 9, 2020, we issued to Bodor 480,769 shares of our common stock, based
on the closing price of $1.04 per share of our common stock on October 8, 2020, as required by the Amended and Restated License Agreement. Such issuance was exempt
from registration under Section 4(a)(2) of the Securities Act.

Our  pivotal  Phase  3  clinical-stage  investigational  product  candidate,  sofpironium  bromide,  is  a  new  chemical  entity  that  belongs  to  a  class  of  medications  called
anticholinergics. Anticholinergics  block  the  action  of  acetylcholine,  a  chemical  that  transmits  signals  within  the  nervous  system  that  are  responsible  for  a  range  of  bodily
functions, including activation of the sweat glands. Sofpironium bromide was retrometabolically designed. Retrometabolic drugs are designed to exert their action locally and
are potentially rapidly metabolized to a less active form once absorbed into the blood. This proposed mechanism of action may allow for potentially highly effective doses to be
used while limiting systemic side effects. We intend to develop sofpironium bromide as a potential best-in-class, self-administered, once daily, topical therapy for the treatment
of primary axillary (underarm) hyperhidrosis.

Hyperhidrosis is a life-altering condition of sweating beyond what is physiologically required for thermoregulation of the body. It is believed to be caused by an overactive
cholinergic response of the sweat glands and affects an estimated 15.3 million, or 4.8%, of the U.S. population. According to a 2016 update on the prevalence and severity of
hyperhidrosis in the U.S. by Doolittle et al., axillary hyperhidrosis, which is the targeted first potential indication for sofpironium bromide, is the most common occurrence of
hyperhidrosis, affecting approximately 65% of patients, or an estimated 10 million individuals, in the U.S.

Collaboration with Kaken in Asia

We and our development partner in Asia, Kaken, have conducted multiple clinical trials of sofpironium bromide gel that encompass over 1,300 subjects in the U.S. and Japan.
These  trials  evaluated  the  potential  safety,  tolerability,  PK,  and  efficacy  of  sofpironium  bromide  gel  in  adult  and  pediatric  patients  with  primary  axillary  hyperhidrosis  and
healthy adult subjects.

In September 2020, Kaken received regulatory approval in Japan to manufacture and market sofpironium bromide gel, 5% under the brand name ECCLOCK   for  the  once-
daily  treatment  of  primary  axillary  hyperhidrosis.  Japan  is  the  first  country  to  approve  sofpironium  bromide,  which  also  marks  the  first  approval  of  a  topical  presentation
product  for  the  treatment  of  primary  axillary  hyperhidrosis  in  Japan.  This  approval  was  based  on  the  results  of  Kaken’s  Japanese  pivotal  Phase  3  registration  study  of
sofpironium bromide gel, 5% in 281 patients with primary axillary hyperhidrosis, in which all primary and secondary efficacy endpoints demonstrated statistically significant
differences between sofpironium bromide gel and vehicle. In addition, sofpironium bromide gel, 5% was observed to be safe and generally well tolerated in this study, as well
as in the accompanying 52-week long-term safety extension study with 185 patients in Japan.

®

In November 2020, Kaken launched commercial sales of ECCLOCK  in Japan. This marked the first commercialization of sofpironium bromide worldwide. Under the Kaken
Agreement,  we  are  entitled  to  receive  commercial  milestone  payments,  as  well  as  tiered  royalties  based  on  a  percentage  of  net  sales  of  sofpironium  bromide  gel  in  Japan.
Furthermore,  Kaken  has  rights  to  develop  and  commercialize  sofpironium  bromide  in  South  Korea,  China,  and  certain  other Asian  countries,  and  we  are  entitled  to  receive
royalties based on a percentage of Kaken’s net sales in these countries.

®

In March 2019, Kaken completed a Phase 3 trial in patients with primary axillary hyperhidrosis in Japan, achieving statistical significance (p<0.05) on all primary and secondary
endpoints, upon which Kaken filed for, and in September 2020 received, regulatory approval to manufacture and market in Japan sofpironium bromide gel, 5% under the brand
name ECCLOCK  for the treatment of primary axillary (underarm) hyperhidrosis.

®

Together with Kaken, we were granted by the Japanese Patent Office a composition of matter patent with claims directed to the novel polymorphic, or crystalline, forms of
sofpironium  bromide  that  are  being  commercialized  by  Kaken  in  Japan  and  would  be  by  us  in  the  U.S.  subject  to  our  own  ongoing  development  efforts,  and  this  patent  is
expected to provide additional protection for these newly developed and distinct forms in certain countries, including Japan, potentially through 2040.

Our Clinical Programs

U.S. Phase 3 Clinical Studies

Based on the positive results in the clinical trials for sofpironium bromide conducted globally to date by us and Kaken, we initiated during the fourth quarter of 2020 two U.S.
pivotal Phase 3 clinical trials (also referred to as our Phase 3 Program or Cardigan Studies), which are both currently enrolling patients.

In October 2020, we initiated our first of two pivotal U.S. Phase 3 clinical studies evaluating sofpironium bromide gel, 15% for the treatment for primary axillary (underarm)
hyperhidrosis, the Cardigan I Study. The Cardigan I Study is expected to

52

Table of Contents

enroll up to 350 subjects aged nine years and older with primary axillary hyperhidrosis and is a multicenter, randomized, double-blinded, vehicle (placebo)-controlled Phase 3
study to evaluate the safety and efficacy of topically applied sofpironium bromide gel, 15%. Subjects will apply sofpironium bromide or vehicle once daily at bedtime to their
underarms for six consecutive weeks, with a two-week post-treatment follow-up. The co-primary efficacy endpoints of the Cardigan I Study include the proportion of subjects
achieving at least a 2-point improvement on the HDSM-Ax scale, a proprietary and validated PRO measure, and change in GSP, each from baseline to EOT. In addition, safety
and tolerability assessments will be performed throughout the study. As of the date of filing of this Annual Report, we have exceeded 50% enrollment in the Cardigan I study.

In December 2020, we initiated the second of the two pivotal U.S. Phase 3 clinical trials for sofpironium bromide gel, 15% for the primary axillary (underarm) hyperhidrosis,
the Cardigan II Study. The Cardigan II Study will evaluate the safety and efficacy of sofpironium bromide gel, 15% versus vehicle in approximately 350 subjects aged nine
years and older with primary axillary hyperhidrosis. As of the date of filing of this Annual Report, all investigational sites are activated, and enrollment of subjects has begun.

We expect to complete enrollment of the Cardigan Studies in the third quarter of 2021 and anticipate announcing topline results from the Cardigan Studies in the fourth quarter
of 2021. If successful, the results from the Cardigan Studies are expected to form the basis of a prospective NDA in the U.S. for sofpironium bromide gel, 15% for the treatment
of primary axillary hyperhidrosis.

Phase 3 Open-Label Long-Term Safety Study

In July 2020, we completed our 12-month Phase 3 open-label long-term safety study evaluating sofpironium gel 5% and 15% in 300 subjects aged nine years and older with
primary  axillary  hyperhidrosis.  The  study  results  confirmed  to  us  that  sofpironium  bromide  gel,  at  both  concentrations,  was  safe  and  generally  well  tolerated,  which  was
consistent with the earlier Phase 2 clinical trial results. No treatment-related SAEs were observed.

AnGes Collaboration Agreement

In September 2020, we entered into a collaboration agreement with AnGes relating to the development and potential commercialization of AnGes’ proprietary investigational
adjuvanted plasmid DNA vaccine intended to prevent COVID-19. Under the terms of the collaboration agreement, AnGes will continue to lead the development of its vaccine
candidate in Japan, and we will provide information and know-how that could be relevant to such development efforts. If AnGes obtains positive results from its clinical studies
in Japan and we are able to satisfy certain conditions, including raising the required development funding, we would have the right to lead the development efforts in the U.S.
and certain emerging markets. If ultimately approved for sale in the applicable jurisdictions, AnGes would have commercial rights to the vaccine in Japan and we would have
commercial rights in the U.S. and certain emerging markets on terms and conditions to be agreed with AnGes prior to any launch of a vaccine product. AnGes completed a
Phase 1/2 study and is currently conducting a Phase 2/3 clinical study with its vaccine candidate in Japan. If the development process continues based on this effort, a larger
Phase 3 registration study will be required for any regulatory approval.

Significant Financing and Licensing Arrangements

Public Offerings of Common Stock and Warrants

In October 2020, we completed the sale of 19,003,510 shares of our common stock, and, to certain investors, pre-funded warrants to purchase 1,829,812 shares of our common
stock,  and  accompanying  common  stock  warrants  to  purchase  up  to  an  aggregate  of  20,833,322  shares  of  our  common  stock  (the  “October  2020  Offering”).  Each  share  of
common stock and pre-funded warrant to purchase one share of common stock was sold together with a common warrant to purchase one share of our common stock. The
public  offering  price  of  each  share  of  common  stock  and  accompanying  common  warrant  was  $0.72  and  $0.719  for  each  pre-funded  warrant  and  accompanying  common
warrant, respectively. The shares of common stock and pre-funded warrants, and the accompanying common warrants, were issued separately and were immediately separable
upon issuance. The common warrants are exercisable at a price of $0.72 per share of our common stock and will expire five years from the date of issuance. The pre-funded
warrants were exercised in October 2020 at an exercise price of $0.001 per share of our common stock. The October 2020 Offering resulted in net proceeds of approximately
$13.7 million to us after deducting underwriting commissions and discounts and other offering expenses of $1.3 million and excluding the proceeds from the exercise of the
warrants.

53

Table of Contents

In June 2020, we completed the sale of 14,790,133 shares of our common stock, and, to certain investors, pre-funded warrants to purchase 2,709,867 shares of our common
stock,  and  accompanying  common  warrants  to  purchase  up  to  an  aggregate  of  17,500,000  shares  of  our  common  stock  (the  “June  2020  Offering”)  (and  together  with  the
October  2020  Offering,  the  “2020  Offerings”).  Each  share  of  common  stock  and  pre-funded  warrant  to  purchase  one  share  of  our  common  stock  was  sold  together  with  a
common warrant to purchase one share of our common stock. The public offering price of each share of common stock and accompanying common warrant was $1.15 and
$1.149 for each pre-funded warrant and accompanying common warrant, respectively. The shares of common stock and pre-funded warrants, and the accompanying common
warrants, were issued separately and were immediately separable upon issuance. The pre-funded warrants were exercised in the third quarter of 2020 at an exercise price of
$0.001 per share of our common stock. The common warrants were immediately exercisable at a price of $1.25 per share of our common stock and will expire five years from
the date of issuance. The June 2020 Offering resulted in approximately $18.7 million of net proceeds after deducting underwriting commissions and discounts and other offering
expenses of $1.4 million and excluding the proceeds from the exercise of the warrants.

We are using the proceeds from the 2020 Offerings for research and development, including clinical trials, working capital, and general corporate purposes.

At Market Issuance Sales Agreement

In April  2020,  we  entered  into  an At  Market  Issuance  Sales Agreement  (the  “ATM Agreement”)  with  Oppenheimer  &  Co.  Inc.  (“Oppenheimer”)  as  our  sales  agent  (the
“Agent”). Pursuant to the terms of the ATM Agreement, we may sell from time to time through the Agent shares of our common stock having an aggregate offering price of up
to $8.0 million (the “Shares”). The Shares are issued pursuant to our shelf registration statement on Form S-3 (Registration No. 333-236353). Sales of the Shares are made by
means of ordinary brokers’ transactions on The Nasdaq Capital Market at market prices or as otherwise agreed by us and the Agent. Under the terms of the ATM Agreement, we
may also sell the Shares from time to time to the Agent as principal for its own account at a price to be agreed upon at the time of sale. Any sale of the Shares to the Agent as
principal would be pursuant to the terms of a separate placement notice between us and the Agent. We will be significantly limited in our ability to sell shares of our common
stock under the ATM Agreement unless and until the number of authorized shares of our common stock is increased, which would require stockholder approval. During the
year ended December 31, 2020, we sold 4,360,167 Shares under the ATM Agreement at a weighted-average price of $0.85 per share, for aggregate net proceeds of $3.4 million,
after  giving  effect  to  a  3%  commission  to  Oppenheimer  as Agent  plus  initial  expenses  for  executing  the ATM Agreement.  Subsequent  to  December  31,  2020,  and  through
March  9,  2021,  we  sold  1,083,548  shares  of  common  stock  under  the  ATM  Agreement  at  a  weighted-average  price  of  $1.55  per  share,  for  aggregate  net  proceeds  of
$1.6 million.

Private Placement Offerings

In  February  2020,  we  and  Lincoln  Park  entered  into  (i)  a  securities  purchase  agreement  (the  “Securities  Purchase Agreement”);  (ii)  a  purchase  agreement  (the  “Purchase
Agreement”); and (iii) a registration rights agreement (the “Registration Rights Agreement”). Pursuant to the Securities Purchase Agreement, Lincoln Park purchased, and we
sold, (i) an aggregate of 950,000 shares of common stock (the “Common Shares”), (ii) a warrant to initially purchase an aggregate of up to 606,420 shares of common stock at
an exercise price of $0.01 per share (the “Series A Warrant”), and (iii) a warrant to initially purchase an aggregate of up to 1,556,420 shares of common stock at an exercise
price of $1.16 per share (the “Series B Warrant”, and together with the Series A Warrant, the “Warrants”). The aggregate gross purchase price for the Common Shares and the
Warrants was $2.0 million.

Under the terms and subject to the conditions of the Purchase Agreement, we have the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to
purchase, up to $28.0 million in the aggregate of shares of our common stock. Sales of common stock by us, if any, will be subject to certain limitations, and may occur from
time to time, at our sole discretion, over the 36-month period commencing on August 14, 2020 (the “Commencement Date”). Further, we will be significantly limited in our
ability to sell shares of our common stock under the Purchase Agreement unless and until the number of authorized shares of our common stock is increased, which would
require stockholder approval.

Following the Commencement Date, under the Purchase Agreement, on any business day selected by us, we may direct Lincoln Park to purchase up to 100,000 shares of our
common stock on such business day (each, a “Regular Purchase”), provided, however, that (i) the Regular Purchase may be increased to up to 125,000 shares, provided that the
closing sale price of the common stock is not below $3.00 on the purchase date; and (ii) the Regular Purchase may be increased to up to

54

Table of Contents

150,000 shares, provided that the closing sale price of the common stock is not below $5.00 on the purchase date. In each case, Lincoln Park’s maximum commitment in any
single Regular Purchase may not exceed $1,000,000. The purchase price per share for each such Regular Purchase will be based on prevailing market prices of common stock
immediately  preceding  the  time  of  sale.  In  addition  to  Regular  Purchases,  we  may  direct  Lincoln  Park  to  purchase  other  amounts  as  accelerated  purchases  or  as  additional
accelerated purchases if the closing sale price of the common stock exceeds certain threshold prices as set forth in the Purchase Agreement. In all instances, we may not sell
shares of our common stock to Lincoln Park under the Purchase Agreement if it would result in Lincoln Park beneficially owning more than 9.99% of the outstanding shares of
our common stock. As of December 31, 2020, we have not made any sales of our common stock under the Purchase Agreement.

We agreed with Lincoln Park that we will not enter into any “variable rate” transactions with any third party, subject to certain exceptions, for a period defined in the Purchase
Agreement. We have the right to terminate the Purchase Agreement at any time, at no cost or penalty.

Amended and Restated License Agreement with Bodor

In February 2020, we, together with Brickell Subsidiary and Bodor entered into the Amended and Restated License Agreement, which supersedes the License Agreement, dated
December  15,  2012,  entered  into  between  Brickell  Subsidiary  and  Bodor,  as  amended  by Amendment  No.  1  to  License Agreement,  effective  as  of  October  21,  2013,  and
Amendment No. 2 to License Agreement, effective as of March 31, 2015.

The Amended and Restated License Agreement retains with us a worldwide, exclusive license  to  develop,  manufacture,  market,  sell  and  sublicense  products  containing  the
proprietary compound sofpironium bromide based upon the patents referenced in the Amended and Restated License Agreement for a defined field of use. In exchange for
entering into the Amended and Restated License Agreement, settling the previously disclosed dispute, and resolving the associated litigation between us and Bodor, we made
an upfront payment of $1.0 million in cash to Bodor following the execution of the Amended and Restated License Agreement and the settlement agreement by and among the
Company, Brickell Subsidiary, and Bodor, dated February 17, 2020. Additionally, under the original License Agreement and the Amended and Restated License Agreement, we
are required to pay Bodor (i) a royalty on sales of product outside Kaken’s territory, including a low single-digit royalty on sales of certain product not covered by the patent
estate  licensed  from  Bodor;  (ii)  a  specified  percentage  of  all  royalties  we  receive  from  Kaken  for  sales  of  product  within  its  territory;  (iii)  a  percentage  of  non-royalty
sublicensing  income  we  receive  from  Kaken  or  other  sublicensees;  and  (iv)  up  to  an  aggregate  of  $1.8  million  (plus  an  additional  $0.1  million  for  approvals  of  additional
products)  in  cash  payments  and  $1.5  million  of  shares  of  our  common  stock  upon  the  achievement  of  certain  development,  regulatory  and  other  milestones,  including  the
enrollment of the first patient in the U.S. Phase 3 trials. Based on the foregoing, we made a $0.5 million milestone payment to Bodor in June 2020 following the closing of the
June  2020  Offering. Additionally,  in  October  2020,  in  association  with  the  enrollment  of  the  first  patient  in  our  U.S.  Phase  3  pivotal  program,  we  made  a  cash  payment  of
$0.5 million and issued $0.5 million, or 480,769 shares, of our common stock to Bodor. As a result, during the year ended December 31, 2020, we recorded an aggregate of
$1.5  million  as  research  and  development  expense  in  the  consolidated  statements  of  operations.  Further,  following  December  31,  2020,  we  have  begun  to  pay  Bodor  the
required royalties based on the royalty revenue we have recognized from Kaken’s net sales of sofpironium bromide in Japan.

Financial Overview

Our  operations  to  date  have  been  limited  to  business  planning,  raising  capital,  developing  our  pipeline  assets  (in  particular  sofpironium  bromide),  identifying  product
candidates, conducting clinical trials, and other research and development. To date, we have financed operations primarily through funds received from the sale of common
stock and warrants, convertible preferred stock, debt, and convertible notes, funds received from license and collaboration agreements, and cash and investments acquired in
connection with the Merger. We do not have any products approved for sale and have not generated any product sales. Since inception, we have incurred operating losses. We
recorded a net loss of $20.9 million and $23.9 million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, we had an accumulated deficit
of $105.9 million. We expect to continue incurring significant expenses and operating losses for at least the next several years as we:

•    execute our two pivotal Phase 3 clinical trials for sofpironium bromide in the U.S.;
•    contract to manufacture product candidates;

55

Table of Contents

•    advance research and development-related activities to develop and expand our product pipeline;
•    maintain, expand, and protect our intellectual property portfolio;
•    hire additional staff, including clinical, scientific, and management personnel; and
•    add operational and finance personnel to support product development efforts and to support operating as a public company.

We  do  not  expect  to  generate  significant  revenue  unless  and  until  we  successfully  complete  development  of,  obtain  marketing  approval  for,  and  commercialize  product
candidates,  either  alone  or  in  collaboration  with  third  parties.  We  expect  these  activities  may  take  several  years  and  our  success  in  these  efforts  is  subject  to  significant
uncertainty. We expect we will need to raise substantial additional capital prior to the regulatory approval and commercialization of any of our product candidates. Until such
time, if ever, that we generate substantial product revenues, we expect to finance our operations through public or private equity or debt financings, collaborations or licenses, or
other available financing transactions. However, we may be unable to raise additional funds through these or other means when needed.

Key Components of Operations

Revenue

Revenue  generally  consists  of  revenue  recognized  under  our  strategic  collaboration  agreements  for  the  development  and  commercialization  of  our  product  candidates.  Our
strategic collaboration agreements generally outline overall development plans and include payments we receive at signing, payments for the achievement of certain milestones,
and royalties. For these activities and payments, we utilize judgment to assess the nature of the performance obligations to determine whether the performance obligations are
satisfied  over  time  or  at  a  point  in  time  and,  if  over  time,  the  appropriate  method  of  measuring  progress  for  purposes  of  recognizing  revenue.  Prior  to  2020,  we  had  not
recognized  any  royalty  revenue  from  any  collaboration  arrangement.  During  the  year  ended  December  31,  2020,  pursuant  to  the  Kaken Agreement,  we  began  recognizing
royalty revenue earned on a percentage of sales of sofpironium bromide in Japan, and we expect to continue to recognize such royalties going forward. Other than the revenue
we  may  generate  in  connection  with  this  agreement,  we  do  not  expect  to  generate  any  revenue  from  any  product  candidates  that  we  develop  unless  and  until  we  obtain
regulatory approval and commercialize our products or enter into other collaboration agreements with third parties.

Research and Development Expenses

Research and development expenses principally consist of payments to third parties known as CROs. These CROs help plan, organize, and conduct clinical and nonclinical
studies  under  our  direction.  Personnel  costs,  including  wages,  benefits,  and  share-based  compensation,  related  to  our  research  and  development  staff  in  support  of  product
development activities are also included, as well as costs incurred for supplies, preclinical studies and toxicology tests, consultants, and facility and related overhead costs.

Below is a summary of our research and development expenses related to sofpironium bromide by categories of costs for the periods presented. The other expenses category
includes travel, lab and office supplies, clinical trial management software, license fees, and other miscellaneous expenses. We expect our research and development expenses to
increase in future periods during the execution of our Phase 3 program for sofpironium bromide.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel costs, including wages, benefits, and share-based compensation, related to our executive, sales, marketing,
finance, and human resources personnel, as well as professional fees, including legal, accounting, and sublicensing fees.

We  expect  our  overall  general  and  administrative  expenses  to  continue  to  increase  in  the  near  term  as  we  incur  expenses  associated  with  operating  as  a  public  company
compared  to  prior  periods,  which  may  include  increased  insurance  premiums,  investor  relations  expenses,  legal  and  accounting  fees  associated  with  the  expansion  of  our
business and corporate governance, financial reporting expenses, and expenses related to Sarbanes-Oxley and other regulatory compliance obligations.

Total Other Income, Net

Investment and Other Income, Net

Investment  and  other  income,  net  consists  primarily  of  realized  gains  and  losses  associated  with  marketable  securities  and  interest  earned  on  cash  and  cash  equivalent  and
marketable securities balances. Our interest income varies each reporting period depending on our average cash balances during the period and market interest rates. We expect
interest income to fluctuate in the future with changes in average cash balances and market interest rates.

Gain on Extinguishment

Gain on extinguishment consists of the gain realized on the conversion of convertible promissory notes to common stock in August 2019, as described further immediately
below.

Interest Expense

Interest  expense  historically  consisted  primarily  of  interest  and  amortization  related  to  the  issuance  of  $7.4  million  of  convertible  promissory  note  principal  during  the  year
ended December 31, 2019, and principal borrowings of $7.5 million provided by the loan and security agreement entered into with Hercules Capital, Inc. on February 18, 2016
(the “Loan Agreement”). In August 2019, the convertible promissory notes were converted and the Loan Agreement was repaid, and therefore, there was no interest expense
thereafter related to these agreements.

Change in Fair Value of Warrant and Derivative Liability

In connection with the Loan Agreement, we issued warrants to Hercules Capital, Inc., which are exercisable for 9,005 shares of common stock at a per share exercise price of
$33.31. In connection with the convertible promissory notes, we issued warrants which are exercisable for 490,683 shares of common stock at a per share exercise price of
$10.36.

We accounted for the warrants as liabilities at their estimated fair value. The warrants were subject to remeasurement to fair value at each balance sheet date, and any fair value
adjustments  were  recognized  in  the  consolidated  statements  of  operations  within  the  “Change  in  fair  value  of  warrant  and  derivative  liability”  line  item.  The  liability  was
adjusted for changes in fair value through August 2019, and at that time the final warrant liability fair value was reclassified to equity in the consolidated balance sheets and no
longer remeasured to fair value each period.

Critical Accounting Policies and Estimates

We  have  prepared  the  consolidated  financial  statements  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of America  (“U.S.  GAAP”).  The
preparation of these consolidated financial statements requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, expenses,
and related disclosures at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis,
management  evaluates  its  critical  estimates,  including  those  related  to  revenue  recognition,  accrued  research  and  development  expenses,  convertible  promissory  notes,
redeemable convertible preferred stock, warrants, and stock-based compensation. We base our estimates on our historical experience and on assumptions that we believe are
reasonable; however, actual results may differ materially from these estimates under different assumptions or conditions.

57

For information on our significant accounting policies, please refer to Note 2 of the notes to our consolidated financial statements included elsewhere in this Annual Report.

Revenue Recognition

We currently recognize revenue generated primarily from licensing and royalty fees received under the Kaken Agreement. The terms of the agreement include non-refundable
upfront fees, funding of research and development activities, payments based upon achievement of milestones, and royalties on net product sales.

We recognize revenue when our customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for
those goods or services. To determine revenue recognition for arrangements that we determine are within the scope of Accounting Standards Update No. 2014-09, Revenue from
Contracts  with  Customers  (“Topic  606”),  we  perform  the  following  five  steps:  (i)  identify  the  promised  goods  or  services  in  the  contract  with  a  customer;  (ii)  identify  the
performance  obligations  in  the  contract;  (iii)  determine  the  transaction  price,  including  the  constraint  on  variable  consideration;  (iv)  allocate  the  transaction  price  to  the
performance obligations in the contract; and (v) recognize revenue when or as the entity satisfies a performance obligation.

At contract inception, we assess the goods or services promised within each contract, determine those that are performance obligations, and assess whether each promised good
or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance
obligation is satisfied. We utilize judgment to assess the nature of the performance obligation to determine whether the performance obligation is satisfied over time or at a point
in time and, if over time, the appropriate method of measuring progress. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of
performance and related revenue recognition.

Licenses of Intellectual Property

If  a  license  to  our  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the  arrangement,  we  recognize  revenue  from  non-
refundable, up-front fees allocated to the license when the license is transferred to the customer, and the customer can 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 achieved 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 value of the associated
milestone (such as a regulatory submission) is included in the transaction price, which is then allocated to each performance obligation. Milestone payments that are not within
our control or the control of our partner, such as approvals from regulators, are not considered probable of being achieved until those approvals are received. At the end of each
subsequent reporting period, we re-evaluate the probability of achievement of such development milestones and, if necessary, adjust our estimate of the overall transaction price.
Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration, and other revenues and earnings in the period of adjustment and
future periods through the end of the performance obligation period.

Royalties

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and where the license is deemed to be the predominant item to
which the royalties relate, we recognize revenue at the later of (a) when the related sales occur, or (b) when the performance obligation to which some or all of the royalty has
been allocated has been satisfied (or partially satisfied). Prior to 2020, we had not recognized any royalty revenue from any collaboration arrangement. During the year ended
December 31, 2020, pursuant to the Kaken Agreement, we recognized revenue related to tiered royalties earned on a percentage of net sales of sofpironium bromide in Japan of
approximately $27 thousand.

For  a  complete  discussion  of  accounting  for  collaboration  licensing  agreements,  see  Note  2  of  the  notes  to  our  consolidated  financial  statements  included  elsewhere  in  this
Annual Report. Our revenue to date has been generated primarily from licensing and development fees received under the Kaken Agreement.

Research and Development

Research and development costs are charged to expense when incurred and consist of costs incurred for independent and collaboration research and development activities. The
major  components  of  research  and  development  costs  include  formulation  development,  clinical  studies,  clinical  manufacturing  costs,  salaries  and  employee  benefits,
toxicology studies, allocations of various overhead, and occupancy costs. Research costs typically consist of applied research, preclinical, and toxicology work. Pharmaceutical
manufacturing development costs consist of product formulation, chemical analysis, and the transfer and scale-up of manufacturing at contract manufacturers.

As part of the process of recording research and development costs, we are required to estimate and accrue expenses. This process involves the following:

•

communicating with appropriate internal personnel to identify services that have been performed on our behalf and estimating the level of service performed and the
associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost;

•    estimating and accruing expenses in our financial statements as of each balance sheet date based on facts and circumstances known to us at the time; and

•    periodically confirming the accuracy of our estimates with service providers and making adjustments, if necessary.

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

•

payments to CROs in connection with preclinical and toxicology studies and clinical trials;

•    payments to investigative sites in connection with clinical trials;

•    payments to CMOs in connection with the production of clinical trial materials; and

•    professional service fees for consulting and related services.

We base our expense accruals related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and
CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements vary from contract to contract and may result in uneven payment flows.
Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing costs, we
estimate  the  period  over  which  services  will  be  performed  and  the  level  of  effort  to  be  expended  in  each  period.  If  we  underestimate  or  overestimate  the  level  of  services
performed or the costs of these services, our actual expenses could differ from estimates.

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

Recent Accounting Pronouncements

Unless otherwise discussed elsewhere in this Annual Report, we believe that the impact of recently issued guidance to be adopted in the future is not expected to have a material
impact on our consolidated financial statements upon adoption.

Revenue decreased by $6.1 million for the year ended December 31, 2020, compared to the year ended December 31, 2019. Revenue in both periods was driven primarily by
collaboration revenue recognized for research and development activities related to the Kaken Agreement for which Kaken provided research and development funding. The
decrease  in  revenue  recognized  was  attributable  to  our  Phase  3  open-label  long-term  safety  study  of  sofpironium  bromide  gel  and  other  ancillary  clinical  studies  that  were
ongoing in 2019 but were concluded or winding down by the end of the first quarter of 2020. Conducting these studies was the basis for revenue recognition over time, through
the third quarter of 2020, of a $15.6 million research and development payment received from Kaken in the second quarter of 2018. During the fourth quarter of 2020, pursuant
to  the  Kaken Agreement,  we  began  recognizing  royalty  revenue  earned  on  a  percentage  of  net  sales  of  sofpironium  bromide  in  Japan,  which  amounted  to  approximately
$27  thousand  in  that  quarter,  however  we  did  not  receive  any  cash  related  to  such  royalties  because  Kaken  instead  offset  amounts  we  owed  it  under  the  Clinical  Supply
Agreement.

Research and Development Expenses

Research and development expenses decreased by $9.0 million for the year ended December 31, 2020, compared to the year ended December 31, 2019, which was primarily
due to a decrease in clinical and other related regulatory and compliance costs related to sofpironium bromide. Our Phase 3, open-label, long-term safety study of sofpironium
bromide gel and other ancillary clinical studies were ongoing in 2019, but were concluded or winding down by the end of the first quarter of 2020. We began incurring greater
research and development costs upon the initiation of our Phase 3 Cardigan Studies in the fourth quarter of 2020.

General and Administrative Expenses

General and administrative expenses decreased by $0.6 million for the year ended December 31, 2020, compared to the year ended December 31, 2019. This decrease was
primarily  due  to  reduced  professional  fees  of  $1.8  million  resulting  from  legal  and  other  fees  incurred  in  2019  related  to  the  Merger  that  did  not  recur  in  2020,  as  well  as
reduced impairment expense of $0.8 million in 2020 compared to 2019. These reduced expenses were partially offset by higher costs in 2020 of $2.0 million for compensation-
related expense and $0.8 million for directors’ and officers’ liability insurance due to becoming a public company.

Total Other Income, Net

Total other income, net decreased by $0.5 million for the year ended December 31, 2020, compared to the year ended December 31, 2019. The change was primarily due to a
gain of $2.3 million related to the conversion of the convertible promissory notes in August 2019 and a gain of $0.2 million resulting from fair value adjustments to warrant
liabilities during the year ended December 31, 2019, both of which did not recur in 2020. These gains were partially offset by a decrease of $2.1 million in interest expense
related to the issuance of convertible promissory notes in 2019 and principal borrowings provided by the Loan Agreement with a former lender.

Liquidity and Capital Resources

We have incurred significant operating losses and have an accumulated deficit as a result of ongoing efforts to develop our product candidates, including conducting preclinical
and clinical trials and providing general and administrative support for these operations. For the years ended December 31, 2020 and 2019, we had a net loss of $20.9 million
and $23.9 million, respectively. As of December 31, 2020, we had an accumulated deficit of $105.9 million. As of December 31, 2020, we had cash and cash equivalents and
marketable securities of $30.1 million compared to $11.7 million as of December 31, 2019. Subsequent to December 31, 2020, we received aggregate proceeds of $10.5 million
from warrant exercises and sales of shares of our common stock under the ATM Agreement. Since inception, we have financed our operations primarily through funds received
from the sale of common stock and warrants, convertible preferred stock, debt, and convertible notes, payments received under strategic license and collaboration agreements,
and cash and investments acquired in the Merger.

We believe that our cash and cash equivalents as of December 31, 2020, along with aggregate cash proceeds received subsequent to December 31, 2020 of $10.5 million from
warrant exercises and sales of shares of our common stock under the ATM Agreement, are sufficient to fund our operations for at least the next 12 months from the issuance of
this Annual  Report.  We  expect  to  continue  to  incur  additional  substantial  losses  in  the  foreseeable  future  as  a  result  of  our  research  and  development  activities. Additional
funding will be required in the future to continue with our planned development and commercial related activities.

Cash Flows

Since  inception,  we  have  primarily  used  our  available  cash  to  fund  expenditures  related  to  product  discovery  and  development  activities.  The  following  table  sets  forth  a
summary of cash flows for the periods presented:

Net cash used in operating activities

$

$

Net cash used in operating activities of $20.0 million during the year ended December 31, 2020 decreased compared to $36.0 million during the prior year primarily due to the
combined effect of a change in working capital of $12.0 million, which included $6.1 million due to changes in deferred revenue and $7.4 million due to changes in prepaid
expenses related to clinical trials, a decrease in net loss of $3.0 million, a reduction associated with the 2019 gain on extinguishment of debt of $2.3 million, and an increase
associated with the 2019 amortization of a convertible promissory notes discount of $1.4 million.

Investing Activities

Net cash provided by investing activities of $4.5 million during the year ended December 31, 2020 decreased compared to $32.5 million during the prior year. The $28.0 million
decrease was primarily the result of a reduction in 2020 in maturities of marketable securities by $15.0 million and cash received from Vical in the Merger of $13.0 million in
2019.

Financing Activities

Net cash provided by financing activities of $38.4 million during the year ended December 31, 2020 increased compared to $2.6 million during the prior year. The increase was
primarily related to higher net proceeds received in the 2020 period from the issuance of common stock and warrants of $38.0 million and proceeds from the issuance of a note
payable  of  $0.4  million,  compared  to  net  proceeds  received  in  2019  from  the  issuance  of  convertible  promissory  notes  of  $7.4  million,  partially  offset  by  the  repayment  of
principal associated with the Loan Agreement in the 2019 period of $4.8 million.

To the Stockholders and the Board of Directors of Brickell Biotech, Inc.

Report of Independent Registered Public Accounting Firm

Opinion on the Financial Statements
We  have  audited  the  accompanying  consolidated  balance  sheets  of  Brickell  Biotech,  Inc.  (the  Company)  as  of  December  31,  2020  and  2019,  the  related  consolidated
statements  of  operations,  comprehensive  loss,  redeemable  convertible  preferred  stock  and  stockholders’  equity  (deficit)  and  cash  flows  for  each  of  the  two  years  in  the
period  ended  December  31,  2020,  and  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 at December 31, 2020 and 2019, and the results of its operations and its cash flows
for each of the two years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

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

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

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

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

Description of the Matter

Research and development costs

The  Company  incurred  $11.2  million  for  research  and  development  expenses  for  the  year  ended  December  31,  2020,  and  accrued  $3.7
million  and  prepaid  $2.3  million  of  research  and  development  expenses  at  December  31,  2020.  The  completeness  and  valuation  of  certain
clinical study fees incurred in the Company's accrued research and development costs are subject to risk of estimation uncertainty related to
services  received  and  efforts  expended.  As  discussed  in  Note  2  of  the  Company’s  consolidated  financial  statements,  costs  for  certain
development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data
such  as  patient  enrollment,  clinical  site  activations  or  information  provided  to  the  Company  by  its  vendors  on  their  actual  costs  incurred.
Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred.

Auditing  research  and  development  costs  was  complex  and  judgmental  due  to  the  significant  estimation  required  by  management  in
determining the time period over which services will be performed, enrollment of patients, number of sites activated and the level of effort to be
expended  in  each  period.  The  Company  has  contracts  with  multiple  contract  research  organizations  (“CROs”)  that  conduct  and  manage
clinical studies on its behalf. The payment terms of these agreements vary from contract to contract and may result in uneven payment flows.

How We Addressed the
Matter in Our Audit

To test the estimated research and development costs, we performed audit procedures that included, among others, assessing methodologies
and  testing  the  significant  assumptions  discussed  above,  testing  the  underlying  data  used  by  management,  and  assessing  the  historical
accuracy  of  management’s  estimates.  We  performed  inquiries  of  clinical  research  managers  to  understand  the  status  of  significant  trials,
discussed  any  delays  or  new  developments  with  the  studies  to  understand  the  impact  of  the  activity  on  the  accounting  for  the  studies,  and
confirmed directly with CROs the status of significant cost drivers, such as patient enrollment and site activation.

We have served as the Company’s auditor since 2017.

NOTE 1. ORGANIZATION AND NATURE OF OPERATIONS

BRICKELL BIOTECH, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Brickell  Biotech,  Inc.  (the  “Company”  or  “Brickell”)  is  a  clinical-stage  pharmaceutical  company  focused  on  the  development  of  innovative  and  differentiated  prescription
therapeutics for debilitating skin diseases with a focus on our lead asset for the treatment of hyperhidrosis. The Company’s pivotal Phase 3 clinical-stage investigational product
candidate, sofpironium bromide, is a new chemical entity that belongs to a class of medications called anticholinergics. The Company intends to develop sofpironium bromide
as  a  potential  best-in-class,  self-administered,  once  daily,  topical  therapy  for  the  treatment  of  primary  axillary  hyperhidrosis.  The  Company’s  operations  to  date  have  been
limited to business planning, raising capital, developing its pipeline assets (in particular sofpironium bromide), identifying product candidates, conducting clinical trials, and
other research and development.

On August 31, 2019, the Company, then known as Vical Incorporated (“Vical”), and Brickell Biotech, Inc., a then privately-held Delaware corporation that began activities in
September 2009 (“Private Brickell”), completed a recapitalization in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated June 2, 2019, as
further amended on August 20, 2019 and on August 30, 2019 (the “Merger Agreement”), by and among Vical, Victory Subsidiary, Inc., a wholly-owned subsidiary of Vical
(“Merger Sub”), and Private Brickell. Pursuant to the Merger Agreement, Merger Sub merged with and into Private Brickell, with Private Brickell surviving as a wholly-owned
subsidiary  of  Vical  (the  “Merger”).  Additionally,  on  August  31,  2019,  immediately  after  the  completion  of  the  Merger,  the  Company  changed  its  name  from  “Vical
Incorporated” to “Brickell Biotech, Inc.” and Private Brickell changed its name from “Brickell Biotech, Inc.” to “Brickell Subsidiary, Inc.”

The  accompanying  consolidated  financial  statements  and  related  notes  reflect  the  historical  results  of  Private  Brickell  prior  to  the  Merger  and  of  the  combined  company
following the Merger, and do not include the historical results of Vical prior to the completion of the Merger.

Liquidity and Capital Resources

The  Company  has  incurred  significant  operating  losses  and  has  an  accumulated  deficit  as  a  result  of  ongoing  efforts  to  develop  product  candidates,  including  conducting
preclinical  and  clinical  trials  and  providing  general  and  administrative  support  for  these  operations.  For  the  year  ended  December  31,  2020,  the  Company  had  a  net  loss  of
$20.9  million  and  net  cash  used  in  operating  activities  of  $20.0  million. As  of  December  31,  2020,  the  Company  had  cash  and  cash  equivalents  of  $30.1  million  and  an
accumulated deficit of $105.9 million.

The Company believes that its cash and cash equivalents as of December 31, 2020, along with the cash proceeds received subsequent to December 31, 2020 as disclosed in Note
10. Subsequent Events, are sufficient to fund its operations for at least the next 12 months from the issuance of these consolidated financial statements. The Company expects to
continue to incur additional substantial losses in the foreseeable future as a result of the Company’s research and development activities. Additional funding will be required in
the future to continue with the Company’s planned development and commercial related activities.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Brickell Subsidiary, Inc., and are presented in U.S.
dollars and prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which include all adjustments necessary for
the  fair  presentation  of  the  Company’s  financial  position,  results  of  operations,  and  cash  flows  for  the  periods  presented. All  significant  intercompany  balances  have  been
eliminated  in  consolidation.  The  Company  operates  in one  operating  segment  and,  accordingly,  no  segment  disclosures  have  been  presented  herein.  The  Company’s
management  performed  an  evaluation  of  its  activities  through  the  date  of  filing  of  these  financial  statements  and  concluded  that  there  are  no  subsequent  events  requiring
disclosure, other than as disclosed.

72

Table of Contents

Use of Estimates

The Company’s consolidated financial statements are prepared in accordance with U.S. GAAP, which requires it to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and contingent liabilities at the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Although these estimates are based on the Company’s knowledge of current events and actions it may take in the future, actual results may
ultimately differ from these estimates and assumptions.

Risks and Uncertainties

The Company’s business is subject to significant risks common to early-stage companies in the pharmaceutical industry including, but not limited to, the ability to develop
appropriate formulations, scale up and produce the compounds; dependence on collaborative parties; uncertainties associated with obtaining and enforcing patents and other
intellectual  property  rights;  clinical  implementation  and  success;  the  lengthy  and  expensive  regulatory  approval  process;  compliance  with  regulatory  and  other  legal
requirements; competition from other products; uncertainty of broad adoption of its approved products, if any, by physicians and patients; significant competition; ability to
manage third-party manufacturers, suppliers, contract research organizations, business partners and other alliances; and obtaining additional financing to fund the Company’s
efforts.

The  product  candidates  developed  by  the  Company  require  approvals  from  the  U.S.  Food  and  Drug  Administration  (“FDA”)  and  foreign  regulatory  agencies  prior  to
commercial  sales  in  the  U.S.  or  foreign  jurisdictions,  respectively.  There  can  be  no  assurance  that  the  Company’s  current  and  future  product  candidates  will  receive  the
necessary approvals. If the Company is denied approval or approval is delayed, it may have a material adverse impact on the Company’s business and its financial condition.

The  Company  expects  to  incur  substantial  operating  losses  for  the  next  several  years  and  will  need  to  obtain  additional  financing  in  order  to  develop  and,  if  successful,
commercialize its product candidates. There can be no assurance that such financing will be available or will be at terms acceptable to the Company.

Cash and Cash Equivalents

The Company considers all highly liquid debt instruments with an original maturity of three months or less from date of purchase to be cash equivalents. Cash equivalents,
which are stated at cost, consist primarily of amounts held in short-term money market accounts with highly rated financial institutions.

Concentrations of Credit Risk

Financial  instruments  that  potentially  subject  the  Company  to  concentrations  of  credit  risk  consist  principally  of  cash  and  cash  equivalents.  The  Company  maintains  cash
balances in several accounts with two financial institutions which, from time to time, are in excess of federally insured limits.

Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation. Expenditures for major betterments and additions are charged to the asset accounts, while replacements,
maintenance, and repairs, which do not improve or extend the lives of the respective assets, are charged to expense as incurred. Depreciation is computed using the straight-line
method over the estimated useful lives of the assets, generally between three and five years. Depreciation expense amounted to approximately $10 thousand and $28 thousand
for the years ended December 31, 2020 and 2019, respectively.

Fair Value Measurements

Fair value is the price that the Company would receive to sell an asset or pay to transfer a liability in a timely transaction with an independent counterparty in the principal
market, or in the absence of a principal market, the most advantageous market for the asset or liability. A three-tier hierarchy is established to distinguish between (1) inputs that
reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity
(observable  inputs)  and  (2)  inputs  that  reflect  the  reporting  entity’s  own  assumptions  about  the  assumptions  market  participants  would  use  in  pricing  an  asset  or  liability
developed based on the best information

73

Table of Contents

available in the circumstances (unobservable inputs), and establishes a classification of fair value measurements for disclosure purposes.

The hierarchy is summarized in the three broad levels listed below:

Level 1—quoted prices in active markets for identical assets and liabilities

Level 2—other significant observable inputs (including quoted prices for similar assets and liabilities, interest rates, credit risk, etc.)

Level 3—significant unobservable inputs (including the Company’s own assumptions in determining the fair value of assets and liabilities)

The  following  table  sets  forth  the  fair  value  of  the  Company’s  financial  assets  measured  at  fair  value  on  a  recurring  basis  based  on  the  three-tier  fair  value  hierarchy  (in
thousands):

(1)    No assets as of each respective date were identified as Level 2 or 3 based on the three-tier fair value hierarchy. The Company had no financial liabilities measured at fair

value on a recurring basis as of each respective date.

Fair Value of Financial Instruments

The following methods and assumptions were used by the Company in estimating the fair values of each class of financial instrument disclosed herein:

Money Market Funds—The  carrying  amounts  reported  as  cash  and  cash  equivalents  in  the  consolidated  balance  sheets  approximate  their  fair  values  due  to  their  short-term
nature and/or market rates of interest (Level 1 of the fair value hierarchy).

U.S. Treasuries—The Company designated its investments in U.S. treasury securities as available-for-sale securities and accounted for them at their respective fair values. The
securities  were  classified  as  short-term  or  long-term  based  on  the  nature  of  the  securities  and  their  availability  to  meet  current  operating  requirements.  Securities  that  were
readily  available  for  use  in  current  operations  are  classified  as  short-term  available-for-sale  marketable  securities  and  are  reported  as  a  component  of  current  assets  in  the
consolidated balance sheets (Level 1 of the fair value hierarchy).

Securities  classified  as  available-for-sale  are  measured  at  fair  value,  including  accrued  interest,  with  temporary  unrealized  gains  and  losses  reported  as  a  component  of
stockholders’ equity until their disposition. The Company reviews available-for-sale securities at the end of each period to determine whether they remain available-for-sale
based  on  its  then-current  intent.  The  cost  of  securities  sold  is  based  on  the  specific  identification  method.  The  securities  are  subject  to  a  periodic  impairment  review. An
impairment charge would occur when a decline in the fair value of the investments below the cost basis is judged to be other-than-temporary.

Leases

The Company accounts for leases under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 842, Leases (“ASC 842”). Under
ASC 842, the Company determines if an arrangement is a lease at inception. Leases with a term greater than one year are recognized on the balance sheet as right-of-use assets,
lease liabilities and, if applicable, long-term lease liabilities. The Company has elected the practical expedient not to recognize on the balance sheet leases with terms of one
year or less and not to separate lease components and non-lease components for long-term real estate leases. Lease liabilities and their corresponding right-of-use assets are
recorded based on the present value of lease

74

Table of Contents

payments  over  the  expected  lease  term.  The  interest  rate  implicit  in  lease  contracts  is  typically  not  readily  determinable. As  such,  the  Company  estimates  the  incremental
borrowing  rate  based  on  industry  peers  in  determining  the  present  value  of  lease  payments.  The  Company’s  facility  operating  lease  has  one  single  component.  The  lease
component  results  in  a  right-of-use  asset  being  recorded  on  the  balance  sheet,  which  is  amortized  as  lease  expense  on  a  straight-line  basis  in  the  Company’s  consolidated
statements of operations.

Revenue Recognition

The Company recognizes revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be
entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers, 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) the Company satisfies the performance obligations. At contract inception, the Company assesses the goods or
services promised within each contract and assesses whether each promised good or service is distinct and determines those that are performance obligations. The Company
then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

To date, the Company has not received approval for any drug candidates from the FDA.

In March 2015, the Company entered into a license, development, and commercialization agreement (as amended, the “Kaken Agreement”) with Kaken Pharmaceutical Co.,
Ltd.  (“Kaken”).  Under  the  Kaken Agreement,  the  Company  granted  to  Kaken  an  exclusive  right  to  develop,  manufacture,  and  commercialize  the  Company’s  sofpironium
bromide compound, a topical anticholinergic, in Japan and certain other Asian countries (the “Territory”). In exchange, Kaken paid the Company an upfront, non-refundable
payment of $11.0 million (the “upfront fee”). In addition, the Company was entitled to receive aggregate payments of up to $10.0 million upon the achievement of specified
development milestones, and $30.0 million upon the achievement of commercial milestones, as well as tiered royalties based on a percentage of net sales of licensed products in
the Territory. The Kaken Agreement further provides that Kaken will be responsible for funding all development and commercial costs for the program in the Territory. Kaken
was also required to enter into negotiations with the Company, to supply the Company, at cost, with clinical supplies to perform Phase 3 clinical trials in the U.S.

The  Company  evaluates  collaboration  arrangements  to  determine  whether  units  of  account  within  the  collaboration  arrangement  exhibit  the  characteristics  of  a  vendor  and
customer  relationship.  The  Company  determined  that  the  licenses  transferred  to  Kaken  in  exchange  for  the  upfront  fee  were  representative  of  this  type  of  relationship.  If  a
license  to  the  Company’s  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations  identified  in  the  arrangement,  the  Company  recognizes
revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For
licenses that are bundled with other performance obligations, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether
the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing
revenue. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition on a
prospective basis.

Under Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“Topic 606”), the Company evaluated the terms of the Kaken Agreement,
and the transfer of intellectual property and manufacturing rights (the “license”) was identified as the only performance obligation as of the inception of the agreement. The
Company concluded that the license for the intellectual property was distinct from its ongoing supply obligations. The Company further determined that the transaction price
under the arrangement was comprised of the $11.0 million upfront payment, which was allocated to the license performance obligation. The future potential milestone amounts
were not included in the transaction price, as they were all determined to be fully constrained. As part of its evaluation of the development and regulatory milestones constraint,
the Company determined that the achievement of such milestones was contingent upon success in future clinical trials and regulatory approvals, each of which was uncertain at
that time. The Company re-evaluates the transaction price each quarter and as uncertain events are resolved or other changes in circumstances occur. Future potential milestone
amounts would be recognized as revenue from collaboration arrangements, if and when they become unconstrained. The remainder of the arrangement, which largely consisted
of  both  parties  incurring  costs  in  their  respective  territories,  provides  for  the  reimbursement  of  the  ongoing  supply  costs.  These  costs  were  representative  of  a  collaboration
arrangement outside of the scope of Topic 606 as they do not have the characteristics of a vendor and customer relationship.

75

Table of Contents

Reimbursable program costs are recognized proportionately with the delivery of drug substance and are accounted for as reductions to research and development expense and
are excluded from the transaction price.

In May 2018, the Company entered into an amendment to the Kaken Agreement, pursuant to which the Company received an upfront non-refundable fee of $15.6 million (the
“Kaken  R&D  Payment”),  which  was  initially  recorded  as  deferred  revenue,  to  provide  the  Company  with  research  and  development  funds  for  the  sole  purpose  of
conducting  certain  clinical  trials  and  other  such  research  and  development  activities  required  to  support  the  submission  of  a  new  drug  application  for  sofpironium  bromide.
These clinical trials have a benefit to Kaken and have the characteristics of a vendor and customer relationship. The Company has accounted for the Kaken R&D Payment under
the provisions of Topic 606. This Kaken R&D Payment is recognized using an input method in proportion to the cost incurred. Upon receipt of the Kaken R&D Payment, on
May 31, 2018, a milestone payment originally due upon the first commercial sale in Japan was removed from the Kaken Agreement and all future royalties to the Company
under the Kaken Agreement were reduced 150 basis points.

During the years ended December 31, 2020 and 2019, the Company recognized revenue of $1.8 million and $7.9 million, respectively, related to the Kaken R&D Payment. As
of  December  31,  2019,  the  Company  had  a  deferred  revenue  balance  related  to  the  Kaken  R&D  Payment  of  $1.8  million,  which  is  recorded  as  deferred  revenue  on  the
accompanying consolidated balance sheet. As of December 31, 2020, there was no remaining deferred revenue balance related to the Kaken R&D Payment.

Milestones

At  the  inception  of  each  arrangement  that  includes  milestone  payments  (variable  consideration),  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 transaction price. Milestone payments that are not within the Company or the Company’s collaboration partner’s
control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each
performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are
satisfied. At  the  end  of  each  subsequent  reporting  period,  the  Company  re-evaluates  the  probability  of  achievement  of  such  milestones  and  any  related  constraint,  and  if
necessary,  adjusts  the  Company’s  estimate  of  the  overall  transaction  price. Any  such  adjustments  are  recorded  on  a  cumulative  catch-up  basis,  which  would  affect  license,
collaboration, or other revenues and earnings in the period of adjustment.

To date, Kaken has paid the Company $10.0 million in milestone payments under the Kaken Agreement.

Royalties

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed to be the predominant item to
which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the
royalty has been allocated has been satisfied (or partially satisfied). Prior to 2020, the Company had not recognized any royalty revenue from any collaboration arrangement. In
September  2020,  Kaken  received  regulatory  approval  in  Japan  to  manufacture  and  market  sofpironium  bromide  gel,  5%  for  the  treatment  of  primary  axillary  (underarm)
hyperhidrosis. During the year ended December 31, 2020, the Company recognized royalty revenue earned on a percentage of net sales of sofpironium bromide in Japan of
approximately $27 thousand.

Research and Development

Research and development costs are charged to expense when incurred and consist of costs incurred for independent and collaboration research and development activities. The
major  components  of  research  and  development  costs  include  formulation  development,  clinical  studies,  clinical  manufacturing  costs,  salaries  and  employee  benefits,
toxicology studies, allocations of various overhead, and occupancy costs. Research costs typically consist of applied research, preclinical, and toxicology work. Pharmaceutical
manufacturing development costs consist of product formulation, chemical analysis, and the transfer and scale-up of manufacturing at contract manufacturers.

76

Table of Contents

Clinical Trial Accruals

Expense  accruals  related  to  clinical  trials  are  based  on  the  Company’s  estimates  of  services  received  and  efforts  expended  pursuant  to  contracts  with  multiple  research
institutions and third-party clinical research organizations that conduct and manage clinical trials on the Company’s behalf. The financial terms of these agreements vary from
contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the
completion of clinical trial milestones. In accruing costs, the Company estimates the period over which services will be performed and the level of effort to be expended in each
period based upon patient enrollment, clinical site activations, or information provided to the Company by its vendors on their actual costs incurred. Any estimates of the level
of services performed or the costs of these services could differ from actual results.

Net Income (Loss) per Common Share

Basic  and  diluted  net  income  (loss)  per  common  share  is  computed  by  dividing  net  income  (loss)  attributable  to  common  stockholders  by  the  weighted  average  number  of
common shares outstanding. When the effects are not anti-dilutive, diluted earnings per share is computed by dividing the Company’s net income (loss) attributable to common
stockholders by the weighted average number of common shares outstanding and the impact of all dilutive potential common shares.

Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the period, including stock options, restricted stock units, and warrants, using
the  treasury  stock  method,  and  redeemable  convertible  preferred  stock  and  convertible  promissory  notes,  using  the  if-converted  method.  In  computing  diluted  earnings  per
share, the average stock price for the period is used in determining the number of shares assumed to be issued from the exercise of stock options, the vesting of restricted stock
units, or the exercise of warrants. Potentially dilutive common share equivalents are excluded from the diluted earnings per share computation in net loss periods because their
effect would be anti-dilutive.

The following table sets forth the potential common shares excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive:

The Company accounts for income taxes by using an asset and liability method of accounting for deferred income taxes. Deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation
allowance is recorded to the extent it is more likely than not that a deferred tax asset will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of
a change in tax rates is recognized in operations in the period that includes the enactment date.

The  Company’s  significant  deferred  tax  assets  are  for  net  operating  loss  carryforwards,  tax  credits,  accruals  and  reserves,  and  capitalized  start-up  costs.  The  Company  has
provided a valuation allowance for its entire net deferred tax assets since inception as, due to its history of operating losses, the Company has concluded that it is more likely
than not that its deferred tax assets will not be realized.

The Company classifies interest and penalties arising from the underpayment of income taxes in the consolidated statements of operations and comprehensive loss as general
and administrative expenses. No such expenses were recognized during the years ended December 31, 2020 and 2019.

In  March  2019,  the  Company  initiated  a  convertible  promissory  notes  offering  pursuant  to  which  the  Company  issued  unsecured  convertible  promissory  notes  (the  “Prom
Notes”), bearing interest at 12.0% with a maturity of one year. Through August 31, 2019, the Company had raised an aggregate principal amount of $7.4 million in Prom Notes,
including $1.7 million from certain of the Company’s management and board of directors. On August 31, 2019, immediately prior to the Merger, the Prom Notes and related
accrued interest converted into 1,069,740 shares of Private Brickell common stock at a conversion price of $7.54 per share.

The Prom Notes also provided for the issuance of warrants at 50% coverage, to acquire 490,683 shares of common stock. The warrants are exercisable for a term of five years at
an exercise price of $10.36. The Company evaluated the various financial instruments under ASC 480, “Distinguishing Liabilities from Equity,” and ASC 815, “Derivatives
and Hedging” (“ASC 815”), and determined the warrants required fair value accounting. The fair value of the warrants was recorded as a warrant liability upon issuance. The
fair value of the warrants on the dates of issuance of $1.5 million was determined with the assistance of a third-party valuation firm. The fair value of the warrants was recorded
as a debt discount upon issuance and was amortized to interest expense over the term of the Prom Notes based on the effective interest method.

At inception of the Prom Notes offering, the Company analyzed the conversion feature of the agreement for derivative accounting consideration under ASC 815 and determined
that the embedded conversion features should be classified as a derivative, which was required to be bifurcated and recorded as a derivative liability.

The  embedded  derivative  for  the  Prom  Notes  was  carried  on  the  Company’s  consolidated  balance  sheets  at  fair  value.  The  derivative  liability  was  marked-to-market  each
measurement period and any change in fair value was recorded as a component of the statements of operations. The fair value of the derivative liabilities on the date of issuance
of $1.4 million was determined with the assistance of a third-party valuation firm. The fair value of the conversion feature was recorded as a debt discount upon issuance and
was amortized to interest expense over the term of the Prom Notes based on the effective interest method.

During the year ended December 31, 2019, the Company recognized $2.0 million of interest expense, including $0.8 million of accretion of discounts using an effective interest
rate of 12.0%. As a result of the conversion on August 31, 2019, the Prom Notes payable, warrant liability, and derivative liability balances were reclassified to equity in the
consolidated balance sheets. A gain of $2.3 million resulted from the conversion of the Prom Notes, which was included in a gain on

extinguishment line in the consolidated statements of operations. During the year ended December 31, 2020, no interest expense was recognized.

NOTE 5. NOTE PAYABLE

Loan Agreement with Hercules Capital, Inc.

On February 18, 2016, the Company entered into a loan and security agreement (the “Loan Agreement”) with Hercules Capital, Inc. (the “Lender”) under which the Company
borrowed $7.5 million upon the execution of the Loan Agreement on February 18, 2016. The interest rate applicable to each tranche was variable based upon the greater of
either (i) 9.2% and (ii) the sum of (a) the Prime Rate as reported in The Wall Street Journal minus 3.5%, plus (b) 9.2%. Payments under the Loan Agreement were interest only
until June 1, 2017, followed by equal monthly payments of principal and interest through the maturity date of September 1, 2019. The Company paid the Lender aggregate
facility fees of $0.2 million in connection with the Loan Agreement.

In connection with the Loan Agreement, the Company issued warrants to the Lender, which are exercisable for 9,005 shares of common stock at a per share exercise price of
$33.31 (the “Hercules Capital Warrants”). The Hercules Capital Warrants will terminate, if not earlier exercised, on February 18, 2026. The fair value of the Hercules Capital
Warrants was recorded at inception as a redeemable convertible preferred stock warrant liability upon issuance.

On September 3, 2019, the Company repaid the remaining outstanding loan balance of $2.6 million and an associated accrued interest and aggregate end-of-term payment of
$0.6 million, and the Loan Agreement was terminated. At the effective time of the Merger, the warrant liability was reclassified to equity in the consolidated balance sheets. As
of December 31, 2020, there were no remaining unaccreted debt discounts and issuance costs.

Paycheck Protection Program

On April  15,  2020,  the  Company  executed  an  unsecured  promissory  note  to  IberiaBank  (the  “PPP  Loan”)  pursuant  to  the  U.S.  Small  Business Administration’s  Paycheck
Protection Program (the “PPP”) under Division A, Title I of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) , which is reported in the consolidated
balance sheet as of December 31, 2020, within the current and long-term note payable line items. A PPP loan is for the purpose of helping businesses keep their workforce
employed during the COVID-19 crisis. The Company used the PPP Loan proceeds to cover payroll costs and certain other permitted costs in accordance with the relevant terms
and conditions of the CARES Act.

The PPP Loan is in the principal amount of $0.4 million, bears interest at a fixed rate of 1.00% per annum, and matures on November 15, 2022. The PPP Loan requires equal
monthly payments of principal and interest commencing on either (1) the date that Small Business Administration remits the Company’s loan forgiveness amount to IberiaBank
or (2) 10 months after the end of the Company’s loan forgiveness covered period. The PPP Loan may be prepaid by the Company at any time prior to maturity without penalty.
As of December 31, 2020, the Company evaluated the uses of proceeds under the PPP Loan with respect to the relevant terms and conditions of the CARES Act and believes
that the full amount of the loan is subject to forgiveness. In January 2021, the Company applied for forgiveness of the full amount of the PPP Loan, which has not yet been
granted.

Operating Leases

In August  2016,  the  Company  entered  into  a five-year  lease  for  office  space  in  Boulder,  Colorado  that  expires  on  October  31,  2021  (the  “Boulder  Lease”)  subject  to  the
Company’s option to renew the Boulder Lease for two additional terms of three years each. Pursuant to the Boulder Lease, the Company leased 3,038 square feet of space in a
multi-suite building. Rent payments under the Boulder Lease included base rent of $4,430 per month during the first year of the Boulder Lease with an annual increase of 3.5%,
and additional monthly fees to cover the Company’s share of certain facility expenses, including utilities, property taxes, insurance, and maintenance, which were $2,160 per
month during the first year of the Boulder Lease.

The  Company  recognized  a  right-of-use  asset  and  corresponding  lease  liability  on  January  1,  2019  by  calculating  the  present  value  of  lease  payments,  discounted  at  the
Company’s estimated incremental borrowing rate of 12.0%, over the 2.8 years

expected remaining term. As the Company’s lease does not provide an implicit rate, the Company estimated the incremental borrowing rate based on industry peers. Industry
peers  consist  of  several  public  companies  in  the  biotechnology  industry  with  comparable  characteristics,  including  the  progress  of  clinical  trials  and  therapeutic  indications.
Amortization of the operating lease right-of-use asset for the Boulder Lease amounted to $0.1 million for the year ended December 31, 2020, which was included in operating
expense.

The  terms  of  the  Boulder  Lease  provide  for  monthly  rental  payments  on  a  graduated  scale.  Lease  expense  for  each  of  the  years  ended  December  31,  2020  and  2019  was
$0.1 million.

The following is a summary of the contractual obligations related to operating lease commitments as of December 31, 2020, and the effect such obligations are expected to have

In February 2020, the Company, together with Brickell Subsidiary and Bodor Laboratories, Inc. and Dr. Nicholas S. Bodor (collectively, “Bodor”) entered into an amended and
restated  license  agreement  (the  “Amended  and  Restated  License Agreement”).  The Amended  and  Restated  License Agreement  supersedes  the  License Agreement,  dated
December  15,  2012,  entered  into  between  Brickell  Subsidiary  and  Bodor,  as  amended  by Amendment  No.  1  to  License Agreement,  effective  as  of  October  21,  2013,  and
Amendment No. 2 to License Agreement, effective as of March 31, 2015.

The Amended  and  Restated  License Agreement  retains  with  the  Company  a  worldwide,  exclusive  license  to  develop,  manufacture,  market,  sell,  and  sublicense  products
containing the proprietary compound sofpironium bromide based upon the patents referenced in the Amended and Restated License Agreement for a defined field of use. In
exchange  for  entering  into  the  Amended  and  Restated  License  Agreement,  settling  the  previously  disclosed  dispute,  and  resolving  the  associated  litigation  between  the
Company and Bodor, the Company made an upfront payment of $ 1.0 million in cash to Bodor following the execution of the Amended and Restated License Agreement and
the settlement agreement by and among the Company, Brickell Subsidiary, and Bodor, dated February 17, 2020. Additionally, under the original License Agreement and the
Amended  and  Restated  License Agreement,  the  Company  is  required  to  pay  Bodor  (i)  a  royalty  on  sales  of  product  outside  Kaken’s  territory,  including  a  low  single-digit
royalty on sales of certain product not covered by the patent estate licensed from Bodor; (ii) a specified percentage of all royalties the Company receives from Kaken for sales of
product  within  its  territory;  (iii)  a  percentage  of  non-royalty  sublicensing  income  the  Company  receives  from  Kaken  or  other  sublicensees;  and  (iv)  up  to  an  aggregate  of
$1.8  million  (plus  an  additional  $0.1  million  for  approvals  of  additional  products)  in  cash  payments  and  $1.5  million  of  shares  of  the  Company’s  common  stock  upon  the
achievement  of  certain  development,  regulatory  and  other  milestones,  including  the  enrollment  of  the  first  patient  in  the  U.S.  Phase  3  trials.  Based  on  the  foregoing,  the
Company made a $0.5 million milestone payment to Bodor in June 2020 following the closing of the June 2020 Offering (see Note 7. “Capital Stock”). Additionally, in October
2020, in association with the enrollment of the first patient in its U.S. Phase 3 pivotal program, the Company made a cash payment of $0.5 million and issued $0.5 million, or
480,769  shares,  of  the  Company’s  common  stock  to  Bodor. As  a  result,  during  the  year  ended  December  31,  2020,  the  Company  recorded  an  aggregate  of  $1.5  million  as
research and development expense in the consolidated statements of operations.

NOTE 7. CAPITAL STOCK

Common Stock

Under the Company’s amended and restated certificate of incorporation, the Company is authorized to issue 100,000,000 shares of common stock with a par value of $0.01 per
share.  Each  share  of  the  Company’s  common  stock  is  entitled  to  one  vote,  and  the  holders  of  the  Company’s  common  stock  are  entitled  to  receive  dividends  when  and  as
declared or paid by its board of directors. The Company has reserved authorized shares of common stock for future issuance at December 31, 2020 as follows:

The Company will be significantly limited in its ability to sell shares of its common stock under the Purchase Agreement or ATM Agreement described below unless and until
the number of authorized shares of common stock of the Company is increased, which would require stockholder approval.

Public Offerings of Common Stock and Warrants

In October 2020, the Company completed a sale of 19,003,510 shares of its common stock, and, to certain investors, pre-funded warrants to purchase 1,829,812  shares  of  its
common stock, and accompanying common stock warrants to purchase up to an aggregate of 20,833,322 shares of its common stock (the “October 2020 Offering”). Each share
of  common  stock  and  pre-funded  warrant  to  purchase  one  share  of  the  Company’s  common  stock  was  sold  together  with  a  common  warrant  to  purchase  one  share  of  the
Company’s common stock. The public offering price of each share of the Company’s common stock and accompanying common warrant was $ 0.72 and $0.719 for each pre-
funded warrant and accompanying common warrant, respectively. The shares of common stock and pre-funded warrants, and the accompanying common warrants, were issued
separately and were immediately separable upon issuance. The common warrants are exercisable at a price of $0.72 per share of the Company’s common stock and will expire
five years from the date of issuance. The pre-funded warrants were exercised in October 2020 at an exercise price of $0.001 per share of the Company’s common stock. The
October 2020 Offering resulted in net proceeds of approximately $13.7 million to the Company after deducting underwriting commissions and discounts and other offering
expenses of $1.3 million and excluding the proceeds from the exercise of the warrants.

In  June  2020,  the  Company  completed  a  sale  of 14,790,133  shares  of  its  common  stock,  and,  to  certain  investors,  pre-funded  warrants  to  purchase 2,709,867  shares  of  its
common stock, and accompanying common stock warrants to purchase up to an aggregate of 17,500,000 shares of its common stock (the “June 2020 Offering”) (and together
with the October 2020 Offering, the “2020 Offerings”). Each share of common stock and pre-funded warrant to purchase one share of common stock was sold together with a
common warrant to purchase one share of common stock. The public offering price of each share of common stock and accompanying common warrant was $1.15 and $1.149
for each pre-funded warrant and accompanying common warrant, respectively. The shares of common stock and pre-funded warrants, and the accompanying common warrants,
were issued separately and were immediately separable upon issuance. The pre-funded warrants were exercised in the third quarter of 2020 at an exercise price of $0.001 per
share of common stock. The common warrants were immediately exercisable at a price of $1.25 per share of common stock and will expire five years from the date of issuance.
The June 2020 Offering resulted in approximately $18.7 million of net proceeds to the Company after deducting underwriting commissions and discounts and other offering
expenses of $1.4 million and excluding the proceeds from the exercise of the warrants. Certain officers of the Company participated in the June 2020 Offering by purchasing an
aggregate purchase price of $0.2 million of the Company's common stock and warrants.

The Company is using the net proceeds from the 2020 Offerings for research and development, including clinical trials, working capital, and general corporate purposes.

At Market Issuance Sales Agreement

In April 2020, the Company entered into an At Market Issuance Sales Agreement (the “ATM Agreement”) with Oppenheimer & Co. Inc. (“Oppenheimer”) as the Company’s
sales agent (the “Agent”). Pursuant to the terms of the ATM Agreement, the Company may sell from time to time through the Agent shares of its common stock having an
aggregate offering price of up to $8.0 million (the “Shares”). The Shares are issued pursuant to the Company’s shelf registration statement on Form S-3 (Registration No. 333-
236353). Sales of the Shares are made by means of ordinary brokers’ transactions on The Nasdaq Capital Market at market prices or as otherwise agreed by the Company and
the Agent. Under the terms of the ATM Agreement, the Company may also sell the Shares from time to time to the Agent as principal for its own account at a price to be agreed
upon at the time of sale. Any sale of the Shares to the Agent as principal would be pursuant to the terms of a separate placement notice between the Company and the Agent.
During the year ended December 31, 2020, the

81

Table of Contents

Company sold 4,360,167 Shares under the ATM Agreement at a weighted-average price of $ 0.85 per share, for aggregate net proceeds of $3.4 million, after giving effect to a
3% commission to Oppenheimer as Agent plus initial expenses for executing the ATM Agreement.

Private Placement Offerings

In February 2020, the Company and Lincoln Park Capital Fund, LLC (“Lincoln Park”) entered into (i) a securities purchase agreement (the “Securities Purchase Agreement”);
(ii)  a  purchase  agreement  (the  “Purchase Agreement”);  and  (iii)  a  registration  rights  agreement  (the  “Registration  Rights Agreement”).  Pursuant  to  the  Securities  Purchase
Agreement, Lincoln Park purchased, and the Company sold, (i) an aggregate of 950,000 shares of common stock (the “Common Shares”); (ii) a warrant to initially purchase an
aggregate of up to 606,420 shares of common stock at an exercise price of $0.01 per share (the “Series A Warrant”); and (iii) a warrant to initially purchase an aggregate of up
to 1,556,420 shares of common stock at an exercise price of $1.16 per share (the “Series B Warrant,” and together with the Series A Warrant, the “Warrants”). The aggregate
gross purchase price for the Common Shares and the Warrants was $2.0 million.

Under  the  terms  and  subject  to  the  conditions  of  the  Purchase Agreement,  the  Company  has  the  right,  but  not  the  obligation,  to  sell  to  Lincoln  Park,  and  Lincoln  Park  is
obligated to purchase, up to $28.0 million in the aggregate of shares of common stock. Sales of common stock by the Company, if any, will be subject to certain limitations, and
may occur from time to time, at the Company’s sole discretion, over the 36-month period commencing on August 14, 2020 (the “Commencement Date”).

Following the Commencement Date, under the Purchase Agreement, on any business day selected by the Company, the Company may direct Lincoln Park to purchase up to
100,000 shares of common stock on such business day (each, a “Regular Purchase”), provided, however, that (i) the Regular Purchase may be increased to up to 125,000 shares,
provided  that  the  closing  sale  price  of  the  common  stock  is  not  below  $3.00  on  the  purchase  date;  and  (ii)  the  Regular  Purchase  may  be  increased  to  up  to 150,000  shares,
provided that the closing sale price of the common stock is not below $5.00 on the purchase date. In each case, Lincoln Park’s maximum commitment in any single Regular
Purchase may not exceed $1,000,000. The purchase price per share for each such Regular Purchase will be based on prevailing market prices of common stock immediately
preceding  the  time  of  sale.  In  addition  to  Regular  Purchases,  the  Company  may  direct  Lincoln  Park  to  purchase  other  amounts  as  accelerated  purchases  or  as  additional
accelerated purchases if the closing sale price of the common stock exceeds certain threshold prices as set forth in the Purchase Agreement. In all instances, the Company may
not sell shares of its common stock to Lincoln Park under the Purchase Agreement if it would result in Lincoln Park beneficially owning more than 9.99% of the outstanding
shares of common stock. As of December 31, 2020, the Company has not made any sales of its common stock under the Purchase Agreement.

The Company agreed with Lincoln Park that it will not enter into any “variable rate” transactions with any third party, subject to certain exceptions, for a period defined in the
Purchase Agreement. The Company has the right to terminate the Purchase Agreement at any time, at no cost or penalty.

The Securities Purchase Agreement, the Purchase Agreement, and the Registration Rights Agreement contain customary representations, warranties, agreements, and conditions
to completing future sale transactions, indemnification rights, and obligations of the parties.

Preferred Stock

Under the Company’s amended and restated certificate of incorporation, the Company’s board of directors has the authority to issue up to 5,000,000 shares of preferred stock
with  a  par  value  of  $0.01  per  share,  at  its  discretion,  in  one  or  more  classes  or  series  and  to  fix  the  powers,  preferences  and  rights,  and  the  qualifications,  limitations,  or
restrictions  thereof,  including  dividend  rights,  conversion  rights,  voting  rights,  terms  of  redemption,  and  liquidation  preferences,  without  further  vote  or  action  by  the
Company’s stockholders. As of December 31, 2020, the Company had  no shares of preferred stock outstanding and had not designated the rights, preferences, or privileges of
any class or series of preferred stock.

Equity Incentive Plans

2020 Omnibus Plan

On April  20,  2020,  the  Company’s  stockholders  approved  the  2020  Omnibus  Long-Term  Incentive  Plan  (the  “Omnibus  Plan”),  which  replaced,  with  respect  to  new  award
grants, the Company’s 2009 Equity Incentive Plan, as amended and restated (the “2009 Plan”), and the Vical Equity Incentive Plan (the “Vical Plan”) (collectively, the “Prior
Plans”) that were previously in effect. Following the approval of the Omnibus Plan on April 20, 2020, no additional grants will be made pursuant to the Prior Plans, but awards
outstanding under those plans as of that date remain outstanding in accordance with their terms. On August 31, 2020, the Company’s stockholders approved an increase in the
number  of  shares  of  common  stock  authorized  for  issuance  under  the  Omnibus  Plan  by 4,500,000. As  of  December  31,  2020, 5,125,000  shares  were  authorized  under  the
Omnibus  Plan  and 3,295,832  shares  were  subject  to  outstanding  awards  under  the  Omnibus  Plan. As  of  December  31,  2020, 2,062,535  shares  remained  available  for  grant
under the Omnibus Plan, subject to limitations as a result of the limited number of available shares due to the Company’s number of authorized shares of common stock at that
date.

2009 Equity Incentive Plan

The 2009 Plan was replaced by the Omnibus Plan on April 20, 2020, and as a result, as of December 31, 2020, there were no remaining shares available for new grants under the
2009 Plan. However, as of December 31, 2020,  1,282,381 shares were subject to outstanding awards under the 2009 Plan, which awards remain outstanding in accordance with
their terms.

Vical Equity Incentive Plan

In connection with the Merger, the Company adopted the Vical Plan, which was replaced by the Omnibus Plan on April 20, 2020. As a result, as of December 31, 2020, there
were no remaining shares available for new grants under the Vical Plan. However, as of December 31, 2020, 253,412 shares were subject to outstanding awards under the Vical
Plan, which awards remain outstanding in accordance with their terms.

Fair Value Assumptions

The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock-based awards. The determination of the fair value of stock-based awards on the
date of grant using an option-pricing model is affected by the value of the Company’s stock price, as well as assumptions regarding subjective variables. These variables include
expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rate, and expected dividends.

Because the Company has a limited history of stock purchase and sale activity, the Company estimates expected volatility of the common stock by using the average share
fluctuations of companies similar in size, operations, and life cycle. The expected term of stock options granted to employees, including members of the board of directors, is
determined as the midpoint between the vesting date and the contractual end of the option grant. The expected term of all other stock options granted is based on the Company’s
historical share option exercise experience, which approximates the midpoint between the vesting date and the contractual end of the option grant. The risk-free interest rates
used in the valuation model are based on U.S. Treasury yield issues in effect at the time of grant for a period commensurate with the expected term of the grant. The Company
does not anticipate paying any dividends in the foreseeable future and therefore uses an expected dividend yield of zero.

Management has estimated a forfeiture rate of 11% based on past history, forfeiture rates, and the individuals receiving the options. The Company monitors actual forfeiture
experience and periodically updates forfeiture estimates based on actual experience.

Stock Options

During the year ended December 31, 2020, the Company granted 3,309,334 stock options to purchase shares of the Company’s common stock with a weighted-average grant
date fair value of $0.52 per share and a weighted-average exercise

Table of Contents

price of $0.80 per share. During the year ended December 31, 2019, the Company granted 1,088,260 stock options with a weighted-average grant date fair value of $3.30 per
share and a weighted-average exercise price of $4.67 per share.

The assumptions used to calculate the fair value of stock options granted are as follows, presented on a weighted-average basis:

As of December 31, 2020, the Company had deferred tax assets of $115.5 million. Due to uncertainties surrounding the Company’s ability to generate future taxable income to
realize these assets, a full valuation allowance has been established to offset the net deferred tax asset.

Pursuant to Sections 382 and 383 of the Internal Revenue Code (“IRC”), annual use of the Company’s NOL and credit carryforwards may be limited in the event a cumulative
change in ownership of more than 50% occurs within a three-year period. In 2019, the Company increased its NOL carryforward by $332.9 million and its credit carryforward
by $23.5 million through the Merger. Vical completed a Section 382 analysis through December 31, 2011 as a result of an ownership change on December 29, 2006,  as defined
in  the  provisions  of  Section  382  of  the  IRC  as  a  result  of  various  stock  issuances  used  to  finance  the  Company’s  operations.  Such  ownership  change  resulted  in  annual
limitations on the utilization of tax attributes, including net operating loss carryforwards and tax credits.

The Company estimates that $76.9 million of Vical’s acquired NOL carryforwards were effectively eliminated under Section 382 for federal tax purposes. The Company also
estimates $8.2 million of Vical’s acquired research and development credits and other tax credits were effectively eliminated under Section 383 for federal purposes. Vical did
not conduct a Section 382 study for periods between December 31, 2011 and the date of the Merger. As such, the Company cannot provide any assurance that a change in
ownership within the meaning of the IRC has not occurred between those dates. There is a risk that additional changes in ownership could have occurred between those dates. It
is further noted, the Company has not completed an IRC 382 and 383 analysis to determine if a change in ownership has occurred since the inception of the Company. If a
change in ownership were to have occurred, additional NOL and tax credit carryforwards could be eliminated or restricted. If eliminated, the related asset would be removed
from the deferred tax asset schedule with a corresponding reduction in the valuation allowance.

As  of  December  31,  2020  and  2019,  the  Company  had  available  federal  NOL  carryforwards  of  approximately  $420.8  million  and  $403.9  million,  respectively.  The  NOL
generated in 2020 of $29.1 million and 2019 of $25.1 million will carry forward indefinitely and be available to offset up to 80% of future taxable income each year. NOLs
generated prior to 2019 will expire from 2020 through 2038. In addition, the Company had federal research and development credits and orphan drug credit carryforwards of
$27.7 million and $30.3 million as of December 31, 2020 and 2019, respectively, to reduce future federal income taxes, if any. The Company also has available state NOL
carryforwards of approximately $382.7 million and $350.8 million as of December 31, 2020 and 2019, respectively. In addition, through the Merger, the Company acquired
Vical’s  California  research  and  development  credits  of  approximately  $ 9.3  million  as  of  December  31,  2020  and  2019,  to  reduce  future  California  income  tax,  if  any.  The
California research and development credits do not expire.

All federal and state NOL and credit carryforwards listed above are reflected before the reduction for amounts effectively eliminated under Sections 382 and 383. Based upon
statute, federal and state NOLs and credits are expected to expire as follows (in thousands):

The Company has evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets. Management has considered the Company’s history of
cumulative net losses incurred since inception and its lack of commercialization of any products and has concluded that it is more likely than not that the Company will not
realize the benefits of the deferred tax assets. Accordingly, a full valuation allowance has been established against the deferred tax assets as of December 31, 2020 and 2019.
Management reevaluates the positive and negative evidence at each reporting period. The Company’s valuation allowance increased by approximately $ 4.9 million for the year
ended December 31, 2020. For the year ended December 31, 2019, the valuation allowance increased by $95.4 million which includes a full valuation allowance against the
acquired deferred tax assets from the Merger.

The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the
weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if
any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believes that it has
appropriate  support  for  the  positions  taken  on  its  tax  returns,  the  Company  regularly  assesses  the  potential  outcome  of  examinations  by  tax  authorities  in  determining  the
adequacy of its provision for income taxes. Before the Merger, the Company had no material unrecognized tax benefits and no adjustments to its financial positions. However,
the Merger brought with it certain unrecognized tax benefits.

As a result of the Merger, the Company acquired gross unrecognized tax benefits with a balance of $21.7 million as of December 31, 2020 and 2019, none of which would
affect the effective tax rate. The Company does not anticipate any significant decreases in its unrecognized tax benefits over the next 12 months. The Company’s policy is to
recognize the interest expense and/or penalties related to income tax matters as a component of income tax expense. The Company had no accrual for interest or penalties on its
balance sheets as of December 31, 2020 and 2019, and has not recognized interest and/or penalties in its statements of operations for the years ended December 31, 2020 and
2019.

As  of  December  31,  2020,  the  Company’s  U.S.  federal  and  state  tax  returns  remain  subject  to  examination  by  tax  authorities  beginning  with  the  tax  year  ended  December
31,  2017.  However,  due  to  NOLs  and  credit  carryforwards  being  generated  and  carried  forward  from  prior  tax  years,  substantially  all  tax  years  may  also  be  subject  to
examination.

NOTE 10. SUBSEQUENT EVENTS

Subsequent to December 31, 2020, and through March 9, 2021, 12,294,887 common warrants associated with the 2020 Offerings were exercised at a weighted-average exercise
price of $0.72 per share, resulting in aggregate proceeds of approximately $8.9 million.

Subsequent to December 31, 2020, and through March 9, 2021, the Company sold 1,083,548 shares of common stock under the ATM Agreement at a weighted-average price of
$1.55 per share, for aggregate net proceeds of $1.6 million.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

Not applicable.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We  maintain  disclosure  controls  and  procedures  that  are  designed  to  ensure  that  information  required  to  be  disclosed  in  the  reports  that  we  file  under  the  Exchange Act  is
recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated
to  our  management,  including  our  principal  executive  officer  and  principal  financial  officer,  as  appropriate,  to  allow  timely  decisions  regarding  required  disclosures.  In
designing  and  evaluating  the  disclosure  controls  and  procedures,  management  recognizes  that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can
provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of
possible controls and procedures.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the
design and operation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) and 15d-15(e) promulgated under the Exchange Act, as of the end of
the period covered by this report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures
were effective and were operating at a reasonable assurance level as of December 31, 2020.

Management Report on Internal Controls over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting  (as  defined  in  Rules  13a-15(f)  and  15d-15(f)  under  the
Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of consolidated financial statements for external purposes
in accordance with U.S. GAAP.

Management assessed our internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by
the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Management’s assessment included evaluation of elements such as the design and
operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment.

Based  on  this  assessment,  management  has  concluded  that  our  internal  control  over  financial  reporting  was  effective  as  of  the  end  of  the  fiscal  year  to  provide  reasonable
assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance with U.S. GAAP.
We reviewed the results of management’s assessment with the audit committee of our board of directors.

Inherent Limitations on Effectiveness of Controls

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

Changes in Internal Control over Financial Reporting

Management has determined that there were no changes in our internal control over financial reporting that occurred during the three months ended December 31, 2020 that
have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As  of  December  31,  2020,  Brickell  Biotech,  Inc.  (the  “Company,”  “we,”  “our”  and  “us”)  maintained  one  class  of  securities  registered  under  Section  12  of  the

Securities Exchange Act of 1934, as amended (the “Exchange Act”): its common stock, par value $0.01 per share (the “Common Stock”).

Description of Common Stock

The  following  is  a  description  of  the  material  terms  of  our  Common  Stock.  The  description  is  qualified  in  its  entirety  by  reference  to  our Amended  and  Restated
Certificate of Incorporation (the “Certificate”), our Amended and Restated Bylaws (the “Bylaws”) and the applicable provisions of the Delaware General Corporation Law, as
amended (the “DGCL”). Our Certificate and Bylaws are incorporated by reference as exhibits to the Annual Report on Form 10-K for the year ended December 31, 2020.

General. Our authorized capital stock consists of 100,000,000 shares of Common Stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value

$0.01 per share. All outstanding shares of Common Stock are duly authorized, validly issued, fully paid and non-assessable.

Voting Rights. The holders of our Common Stock are entitled to one vote for each share held of record on all matters submitted to a vote of our stockholders. The
holders of shares of our Common Stock are not entitled to cumulate their votes in the election of directors, which means that holders of a majority of the outstanding shares of
our Common Stock can elect all of our directors.

Dividend Rights.  The  holders  of  our  Common  Stock  are  entitled  to  receive  ratably  the  dividends,  if  any,  that  may  be  declared  from  time  to  time  by  our  board  of

directors out of funds legally available for such dividends.

Liquidation Rights. In the event of a liquidation, dissolution or winding up of our Company, the holders of our Common Stock would be entitled to share ratably in all

assets remaining after payment of liabilities and the satisfaction of any liquidation preferences granted to the holders of any outstanding shares of preferred stock.

Preemptive Rights. Holders of our Common Stock have no preemptive rights and no conversion rights or other subscription rights. There are no redemption or sinking
fund provisions applicable to our Common Stock. All the outstanding shares of Common Stock are, and all shares of Common Stock offered, when issued and paid for, will be,
validly issued, fully paid and non-assessable. The rights, preferences and privileges of holders of our Common Stock are subject to, and may be adversely affected by, the rights
of the holders of any shares of our preferred stock.

The Nasdaq Capital Market Listing

Our Common Stock is listed on The Nasdaq Capital Market under the symbol “BBI.”

Transfer Agent and Registrar

The transfer agent and registrar for our Common Stock is American Stock Transfer & Trust Company, LLC. Its address is 6201 15th Avenue, Brooklyn, New York

11219 and its telephone number is (800) 937-5449.

Anti-Takeover Provisions

Our Certificate, Bylaws and certain provisions of the DGCL may have an anti-takeover effect. These provisions may delay, defer or prevent a tender offer or takeover
attempt that a stockholder would consider in its best interest. This includes an attempt that might result in a premium over the market price for the shares of Common Stock held
by stockholders. These provisions are expected to discourage certain types of coercive takeover practices and inadequate takeover bids. They are also expected to encourage
persons  seeking  to  acquire  control  of  the  Company  to  negotiate  first  with  our  board  of  directors.  We  believe  that  the  benefits  of  these  provisions  outweigh  the  potential
disadvantages of discouraging takeover proposals because, among other things, negotiation of takeover proposals might result in an improvement of their terms.

Delaware Anti-Takeover Law

We are a Delaware corporation and, as such, we are subject to Section 203 of the DGCL. Section 203 generally prohibits a public Delaware corporation from engaging

in a “business combination” with an “interested

stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

•

•

•

•
•
•
•
•

prior to the date of the transaction, the board of directors of the corporation approved either the business combination or 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  commenced,  excluding  for  purposes  of
determining the number of shares outstanding (a) shares owned by persons who are directors and also officers of the corporation and (b) shares issued under employee
stock plans under 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
on  or  subsequent  to  the  date  of  the  transaction,  the  business  combination  is  approved  by  the  board  of  directors  and  authorized  at  an  annual  or  special  meeting  of
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.

Section 203 defines a business combination to include:

any merger or consolidation involving the corporation and the interested stockholder;
any sale, lease, exchange, mortgage, pledge, transfer or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;
subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;
any transaction involving the corporation that has the effect of increasing the proportionate share of its stock owned by the interested stockholder; or
the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 of the DGCL defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the

corporation and any entity or person associated with, or controlling, controlled by, or under common control with, the entity or person.

Certificate and Bylaws

Some provisions of our Certificate and Bylaws could also have anti-takeover effects. These provisions:

•
•
•
•
•

•

•

provide for a board comprised of three classes of directors with each class serving a staggered three-year term;
authorize our board of directors to issue preferred stock from time to time, in one or more classes or series, without stockholder approval;
require the approval of at least two-thirds of our outstanding voting stock to amend specified provisions of our Certificate;
require the approval of at least two-thirds of our total number of authorized directors, or two-thirds of our outstanding voting stock, to amend our Bylaws;
provide that special meetings of our stockholders may be called only by our Chief Executive Officer, or by our board of directors pursuant to a resolution adopted by a
majority of the total number of authorized directors;
provide  that  vacancies  on  our  board  of  directors  and  newly  created  directorships  may  be  filled  only  by  a  majority  of  the  directors  then  in  office,  though  less  than  a
quorum, or by a sole remaining director; and
do not include a provision for cumulative voting for directors (under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may
be able to ensure the election of one or more directors).

Re: Letter Agreement - Payment for [***] API (“Second API Payment Letter Agreement”)

Dear Andy,

As you know, pursuant to the Letter Agreement for Supply of [***] API - First Amendment ("First API Payment Letter Agreement"), Brickell Biotech,
Inc. ("Brickell") paid Kaken Pharmaceutical Co., Ltd. ("Kaken") for [***] out of a total of [***] API that Kaken delivered to Brickell pursuant to the
Clinical Supply Agreement entered into between Brickell and Kaken dated as of July 30, 2019 ("CSA"). Currently, pursuant to the CSA and the First API
Payment Letter Agreement, Brickell owes Kaken the following amounts:

1.    Principal amount owed for remaining [***] API: Yen [***];

2.    Amount of accrued but unpaid interest on the unpaid principal amounts of the balance owed to Kaken: Yen [***] (as of 9/30/2020); and

3.    Accrued but unpaid storage charges: Yen [***] (as of 9/30/2020).

In addition, interest and storage charges are continuing to accrue at the rates set forth in the CSA and the First API Payment Letter Agreement. All of
the above amounts are past due. As mentioned in the First API Payment Letter Agreement, Kaken reserves all rights at law and in equity with respect
to all amounts that Brickell owes Kaken.

More specifically, Kaken commenced sales of ECCLOCK® Gel 5% (INN: sofpironium bromide, code name: BBI-4000, “ECCLOCK®”) in Japan for primary
axillary hyperhidrosis on November 26, 2020 and, as such, Kaken will now owe Brickell royalty payments in the first quarter of 2021 pursuant to the
License, Development & Commercialization Agreement between Brickell and Kaken, executed March 15, 2015 and as subsequently amended (“LDCA”).
Given this situation, Kaken desires to confirm Brickell’s agreement to pay Kaken amounts that Brickell owes for the [***] API as follows:

1.     Kaken will offset all amounts that Brickell owes Kaken for the [***] API, including interest and storage charges, against royalty and other payments
that Kaken will owe to Brickell pursuant to the LDCA until all amounts that Brickell owes Kaken are fully paid, provided that Kaken will not reduce the
amount of any royalty payment that would otherwise be due to Brickell under the LDCA by more than [***] so that Brickell would be able to pay Bodor
Laboratories, Inc. (“Bodor”) sublicense royalties that Brickell will owe Bodor pursuant to the Amended and Restated License Agreement dated
February 17, 2020 entered into between Brickell and Bodor (“ARLA”). Brickell will promptly send Kaken a copy of the wire transfer confirmation receipt
or other similar document reasonably acceptable to Kaken evidencing Brickell’s timely payment to Bodor of all sublicense royalties that Brickell owes
to Bodor pursuant to the ARLA.

    2.    Kaken will credit amounts that Kaken offsets pursuant to Paragraph 1 against the following, in order: (i) accumulated storage charges, (ii)
accrued interest and (iii) the unpaid principal amount that Brickell owes Kaken for the [***] API and Kaken will set forth the calculation of the amounts
Kaken offsets against the amounts owed by Brickell in each statement that Kaken will

provide to Brickell pursuant to Section 8.3.4 of the LDCA (“Statement”). All unpaid amounts will continue to bear interest at the rate of [***] per
annum on the basis of a 360-day year.

    3.    At any time after prior written notice by Brickell to Kaken of thirty (30) calendar days following payment by Brickell to Kaken hereunder by
royalty offset, Kaken will make available at [***] to a carrier designated by Brickell an amount of API in kg equal to: [***] rounded down to the lowest
[***] (which is the storage capacity of each container in which the API is stored); provided that Kaken shall have no obligation to make any API
available to Brickell’s carrier unless Kaken has an obligation pursuant to this Paragraph 3 to make at least [***] of API available to Brickell’s carrier,
except that this proviso shall not apply when the total remaining amount of API in storage is less than [***]. Storage charges shall continue to accrue
for API at the rates set forth in the CSA and Letter Agreement until Brickell’s carrier takes delivery of all remaining [***] API.

    4.    At any time until Kaken has fully offset all amounts owed by Brickell against royalty and other payments owed by Kaken to Brickell pursuant to
this Second API Payment Letter Agreement, Brickell shall have the right, exercisable upon [***] calendar days’ written notice to Kaken to pay all
amounts that Brickell then owes Kaken for the [***] API. Brickell’s notice shall set forth the business day on which Brickell’s designated carrier will take
delivery of all remaining API in storage, promptly following the expiration of the full [***] calendar day advance notice period (“Pick-up Date”), and
such other details concerning Brickell’s designated carrier as Kaken shall reasonably require. Within [***] calendar days after receipt of such notice
from Brickell, Kaken shall send Brickell an invoice for the principal balance amount that Brickell owes Kaken for the remaining API in storage and
storage charges for the API calculated through later of the Pick-Up Date or the date through which Kaken will incur storage charges. Brickell shall pay
Kaken all amounts set forth in Kaken’s invoice by means of wire transfer to such bank account as designated in writing by Kaken in immediately
available funds without any set-off or deduction for any reason no later than [***] calendar days before the date Brickell has indicated its common
carrier will take delivery of all remaining API. Kaken shall send Brickell a subsequent invoice for the amount of accrued interest calculated through the
date Kaken confirms receipt in full of all amounts set forth in Kaken’s first invoice within [***] calendar days after confirming receipt of all such
amounts. Brickell shall pay Kaken the amount of accrued interest set forth in Kaken’s invoice within [***] calendar days after the date of Kaken’s
invoice by means of wire transfer to such bank account as designated in writing by Kaken in immediately available funds without any set-off or
deduction for any reason. Kaken shall have no obligation to make any API available to Brickell’s carrier unless Kaken is able to confirm receipt in full of
the amounts set forth in its first and second invoices [***] calendar days prior to the date Brickell has indicated its common carrier will take delivery of
all API.

Please kindly signify Brickell's agreement to pay Kaken all amounts owed for the [***] API pursuant to the terms of this Second API Payment Letter
Agreement by signing below where indicated and return a signed copy of this Second API Payment Letter Agreement to my attention.

Sincerely yours,

Agreed this 8  day of December, 2020

By:

Title:

BRICKELL BIOTECH, INC.
2020 Omnibus Long-Term Incentive Plan
Incentive Stock Option Award Agreement

Terms and Conditions

1.    Incentive Stock Option. This Option is intended to be an “incentive stock option” within the meaning of Section 422 of the Internal Revenue Code
(the “Code”) and will be interpreted accordingly. To the extent that, for any reason, the Option does not qualify as an incentive stock option under Code
Section 422, the Option will be treated as a non-statutory stock option, subject to the tax consequences applicable to such options.

2.    Vesting and Exercisability of Option.

(a)    Scheduled Vesting. This Option will vest and become exercisable as to the number of shares of Common Stock (“Shares”) and on the dates
specified in the Vesting and Exercise Schedule on the cover page to this Agreement, so long as you remain a Service Provider (which is defined as an
individual who has not experienced a Termination Date) on such dates. The Vesting and Exercise Schedule is cumulative, meaning that to the extent the
Option has not already been exercised and has not expired or been terminated or cancelled, you or the person otherwise entitled to exercise the Option as
provided in this Agreement may at any time purchase all or any portion of the Shares subject to the vested portion of the Option.

(b)    Accelerated Vesting. The vesting of outstanding Options will be accelerated under the circumstances provided below:

(1)

Death or Disability. If your service to the Company or Related Companies terminates prior to the final Scheduled Vesting Date
due to your death or Disability, then a pro rata portion (based on the number of days during which you were a Service Provider since the most
recent Scheduled Vesting Date (or since the Grant Date if there was no previous Scheduled Vesting Date) as a percentage of the total number of
days between such date and the next Scheduled Vesting Date) of the Options scheduled to vest as of the next Scheduled Vesting Date shall vest as
of such Termination Date.

(2)

Change in Control . If a Change in Control occurs while you continue to be a Service Provider and prior to the final Scheduled

Vesting Date, the following provisions shall apply:

(a)

If,  within  24  months  after  a  Change  of  Control  (A)  described  in  Section  2.6(a)  or  Section  2.6(d)  of  the  Plan  or  (B)
described in Section 2.6(b) of the Plan and in connection with which the surviving or acquiring entity (or its parent entity) has continued,
assumed or replaced this Award, you cease to be a Service Provider due either to an involuntary termination for reasons other than Cause
(as  defined  in  Section  11  below)  or  a  resignation  for  Good  Reason  (as  defined  in  Section  11  below),  then  all  unvested  Options  shall
immediately vest in full.

(b)

If this Award is not continued, assumed or replaced in connection with a Change in Control pursuant to Section 2.6(b) of

the Plan, then all unvested Options shall

2

immediately vest in full upon the occurrence of the Change in Control and paid out in accordance with Section 7.2 of the Plan.

(c)

In the event of a Change of Control described in Section 2.6(c) of the Plan, then all unvested Options shall immediately

vest in full upon the occurrence of the Change in Control and paid out in accordance with Section 7.2 of the Plan.

(3)

Other Agreements or Plans.   Unvested Options shall also vest as provided in any separate employment (or similar) agreement or

severance plan to which you are a party or a participant.

3.    Expiration. This Option will expire and will no longer be exercisable at 5:00 p.m. Eastern Time on the earliest of:

(a)

(b)

(c)

The expiration date specified on the cover page of this Agreement;

Upon your Termination Date if you are terminated for Cause;

Upon the expiration of any applicable period specified in Sections 2 and 4 of this Agreement during which this Option may be exercised

after your termination of service; or

(d)    The date (if any) fixed for termination or cancellation of this Option pursuant to Section 7.2 of the Plan.

4.    Service Requirement. Except as otherwise provided below or in Section 2 of this Agreement, this Option may be exercised only while you continue
to provide service to the Company or Related Companies, and only if you have continuously provided such service since the Grant Date of this Option.
If your service with the Company and all the Related Companies terminates, the following provisions shall apply:

(a)

(b)

consideration.

Upon termination of service for Cause, all unexercised Options shall be immediately forfeited without consideration.

Upon  termination  of  service  for  any  other  reason,  all  unexercisable  portions  of  the  Options  shall  be  immediately  forfeited  without

(c)

Upon  termination  of  service  for  any  reason  other  than  Cause,  death  or  Disability,  the  currently  vested  and  exercisable  portion  of  the
Options may be exercised for a period of three months after the date of such termination. However, if a Participant thereafter dies during such three-
month period, the vested and exercisable portion of the Options may be exercised for a period of one year after the date of such termination.

(d)

Upon termination of service due to death or Disability, the currently vested and exercisable portion of the Options may be exercised for a

period of one year after the date of such termination.

5.    Exercise of Option. Subject to Section 4, the vested and exercisable portion of this Option may be exercised in whole or in part at any time during
the Option term by delivering a written or electronic notice of exercise to the person or entity designated by the Company, and by providing for payment
of the exercise price of the Shares being acquired and any related withholding taxes. The notice of exercise must

3

be in a form approved by the Company and state the number of Shares to be purchased, the method of payment of the aggregate exercise price and the
directions for the delivery of the Shares to be acquired, and must be signed or otherwise authenticated by the person exercising the Option. If you are not
the person exercising the Option, the person submitting the notice also must submit appropriate proof of his/her right to exercise the Option.

6 .    Payment  of  Exercise  Price.  When  you  submit  your  notice  of  exercise,  you  must  include  payment  of  the  exercise  price  of  the  Shares  being
purchased through one or a combination of the following methods:

(a)

(b)

Cash or by promissory note;

By means of a broker-assisted cashless exercise in which you irrevocably instruct your broker to deliver proceeds of a sale of all or a

portion of the Shares to be issued pursuant to the exercise to the Company in payment of the exercise price of such Shares; or

(c)

By  delivery  to  the  Company  of  Shares  (by  actual  delivery  or  attestation  of  ownership  in  a  form  approved  by  the  Company)  already
owned by you that are not subject to any security interest and that have an aggregate Fair Market Value on the date of exercise equal to the exercise price
of the Shares being purchased.

7.    Tax Consequences. You hereby acknowledge that if any Shares received pursuant to the exercise of any portion of this Option are sold within two
years  from  the  Grant  Date  or  within  one  year  from  the  effective  date  of  exercise  of  this  Option,  or  if  certain  other  requirements  of  the  Code  are  not
satisfied, such Shares will be deemed under the Code not to have been acquired by you pursuant to an “incentive stock option” as defined in the Code.
You  agree  to  promptly  notify  the  Company  if  you  sell  any  Shares  received  upon  the  exercise  of  this  Option  within  the  time  periods  specified  in  the
previous  sentence. The  Company  shall  not  be  liable  to  you  if  this  Option  for  any  reason  is  deemed  not  to  be  an  “incentive  stock  option”  within  the
meaning of the Code.

8.    Delivery of Shares. As soon as practicable after the Company receives the notice of exercise and payment of the exercise price as provided above,
and has determined that all other conditions to exercise, including compliance with applicable laws, have been satisfied, it shall deliver to the person
exercising the Option, in the name of such person, the Shares being purchased, as evidenced by issuance of a stock certificate or certificates, electronic
delivery of such Shares to a brokerage account designated by such person, or book-entry registration of such Shares with the Company’s transfer agent.
The Company shall pay any original issue or transfer taxes with respect to the issue or transfer of the Shares and all fees and expenses incurred by it in
connection therewith. All Shares so issued shall be fully paid and nonassessable.

9.    Transfer of Option. During your lifetime, only you may exercise this Option except in the case of a transfer described below. You may not assign
or transfer this Option except for a transfer upon your death in accordance with your will or by the laws of descent and distribution. The Option held by
any such transferee will continue to be subject to the same terms and conditions that were applicable to the Option immediately prior to its transfer and
may be exercised by such transferee as and to the extent that the Option has become exercisable and has not terminated in accordance with the provisions
of the Plan and this Agreement.

10.    No Stockholder Rights Before Exercise. Neither you nor any permitted transferee of this Option will have any of the rights of a stockholder of the
Company with respect to any Shares subject to this

4

Option  until  a  certificate  evidencing  such  Shares  has  been  issued,  electronic  delivery  of  such  Shares  has  been  made  to  your  designated  brokerage
account, or an appropriate book entry in the Company's stock register has been made. No adjustments shall be made for dividends or other rights if the
applicable  record  date  occurs  before  your  stock  certificate  has  been  issued,  electronic  delivery  of  your  Shares  has  been  made  to  your  designated
brokerage account, or an appropriate book entry in the Company’s stock register has been made, except as otherwise described in the Plan.

11.    Definitions.

( a )    Cause.  “Cause”  shall,  if  you  have  an  employment  agreement  with  the  Company,  have  the  meaning  set  forth  in  your  employment
agreement.  If  you  do  not  have  an  employment  agreement  with  the  Company,  “Cause”  means:  (i)  an  action  or  omission  of  the  Participant  which
constitutes  a  willful  and  material  breach  of,  or  failure  or  refusal  (other  than  by  reason  of  his  disability)  to  perform  his  duties  under  any  agreement
between the Participant and the Company or the Related Companies which is not cured within fifteen (15) days after receipt by the Participant of written
notice of same; (ii) fraud, embezzlement, misappropriation of funds or breach of trust in connection with his services to the Company or the Related
Companies; (iii) conviction of any crime which involves dishonesty or a breach of trust; or (iv) gross negligence in connection with the performance of
the Participant’s duties, which is not cured within fifteen (15) days after written receipt by the Participant of written notice of same.

( b )    Disability. “Disability” means (i) any permanent and total disability under any long-term disability plan or policy of the Company or the
Related Companies that covers the Participant, or (ii) if there is no such long-term disability plan or policy, “total and permanent disability” within the
meaning of Code Section 22(e)(3).

( c )    Good  Reason.  “Good  Reason”  shall,  if  you  have  an  employment  agreement  with  the  Company,  have  the  meaning  set  forth  in  your
employment agreement. If you do not have an employment agreement with the Company, “Good Reason” means (i) the assignment to the Participant of
any  duties  inconsistent  in  any  respect  with  the  Participant’s  position  (including  status,  offices,  titles  and  reporting  requirements),  authority,  duties  or
responsibilities, or any other action by the Company which results in a diminution in such position, authority, duties or responsibilities, excluding for this
purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly after receipt of notice
thereof  given  by  the  Participant;  (ii)  any  failure  by  the  Company  to  comply  with  any  of  the  compensation-related  provisions  of  any  employment
agreement  to  which  the  Participant  is  a  party,  other  than  an  isolated,  insubstantial  and  inadvertent  failure  not  occurring  in  bad  faith  and  which  is
remedied  by  the  Company  promptly  after  receipt  of  notice  thereof  given  by  the  Participant; provided however,  that  in  order  to  effect  resignation  for
Good Reason all of the following must occur: (x) Participant must provide the Company with written notice within the sixty-day period following the
event(s) giving rise to Participant’s intent to voluntarily resign his employment for Good Reason (y) such event is not remedied by within thirty (30)
days  following  the  Company’s  receipt  of  such  written  notice;  and  (z)  Participant’s  resignation  is  effective  not  later  than  thirty  (30)  days  after  the
expiration of such thirty (30) day cure period.

12.    Additional Provisions.

(a)

No  Right  to  Continued  Service.  This  Agreement  does  not  give  you  a  right  to  continued  service  with  the  Company  or  the  Related
Companies, and the Company and the Related Companies may terminate your service at any time and otherwise deal with you without regard to the
effect it may have upon you under this Agreement.

5

(b)

Governing Plan Document. This Agreement and Option are subject to all the provisions of the Plan, and to all interpretations, rules and
regulations  which  may,  from  time  to  time,  be  adopted  and  promulgated  by  the  Committee  pursuant  to  the  Plan.  If  there  is  any  conflict  between  the
provisions of this Agreement and the Plan, the provisions of the Plan will govern. If there is any conflict between this Agreement or the Plan and any
separate employment (or similar) agreement or severance plan to which you are a party or a participant, the provisions of the other agreement or plan
will govern.

(c)

Choice of Law. This Agreement will be interpreted and enforced under the laws of the state of Delaware (without regard to its conflicts

or choice of law principles).

(d)

Severability. The provisions of this Agreement shall be severable and if any provision of this Agreement is found by any court to be
unenforceable, in whole or in part, the remainder of this Agreement shall nevertheless be enforceable and binding on the parties. You also agree that any
trier  of  fact  may  modify  any  invalid,  overbroad  or  unenforceable  provision  of  this  Agreement  so  that  such  provision,  as  modified,  is  valid  and
enforceable under applicable law.

(e)

Binding  Effect.  This  Agreement  will  be  binding  in  all  respects  on  your  heirs,  representatives,  successors  and  assigns,  and  on  the

successors and assigns of the Company.

(f)

Other Agreements. You agree that in connection with the exercise of this Option, you will execute such documents as may be necessary
