</FONT>As of September 30, 2018, the Company had an accumulated deficit of $19,806 and has incurred negative cash flow from
operating activities since its inception. The Company currently believes its existing cash and cash equivalents, together
with the net cash proceeds received from the closing of its IPO on November 15, 2018 of $22,603 (see Note 12), will
be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 24 months from the date
of issuance of these financial statements. This estimate is based on the Company&rsquo;s current assumptions, including assumptions
relating to its ability to manage its spending. The Company could use its available capital resources sooner than currently expected.
Accordingly, t<FONT STYLE="background-color: white">he Company could seek to obtain additional capital through equity financings,
the sale of debt or other arrangements. However, there can be no assurance that the Company will be able to raise additional capital
if needed or under acceptable terms, if at all. The sale of additional equity may dilute existing stockholders and newly
issued shares may contain senior rights and preferences compared to currently outstanding common shares. Issued debt securities
may contain covenants and limit the Company&rsquo;s ability to pay dividends or make other distributions to stockholders. If the
Company is delayed in completing its product development and obtaining regulatory approval for its product candidates and
is unable to obtain such additional financing, operations would need to be scaled back or discontinued.</FONT></FONT></P>

Company accounts for stock-based compensation under the provisions of the Financial Accounting Standards Board (the &ldquo;FASB&rdquo;)
Accounting Standards Codification (&ldquo;ASC&rdquo;) &mdash; 718 Compensation &mdash; Stock Compensation. The guidance under
ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant for employees
and directors and record expense over the related service periods, which are generally the vesting period of the equity awards.
Awards for consultants are accounted for under ASC 505-50 &mdash; Equity Based Payments to Non-Employees. Compensation expense
is recognized over the period during which services are rendered by such consultants and non-employees until completed. At the
end of each financial reporting period prior to completion of the service, the fair value of these awards is remeasured using
the then-current fair value of the Company&rsquo;s common stock and updated assumption inputs in the Black-Scholes-Merton
option-pricing model (&ldquo;BSM&rdquo;).</FONT></P>

Company estimates the fair value of stock-based option awards to its employees and directors using the BSM. The BSM requires the
input of subjective assumptions, including the expected stock price volatility, the calculation of expected term, forfeitures
and the fair value of the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined
from the implied yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options
or warrants. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of
stock options granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on
comparable companies&rsquo; historical volatility, which management believes represents the most accurate basis for estimating
expected future volatility under the current conditions. The Company accounts for forfeitures as they occur.</FONT></P>

from lease contracts, including existing and new arrangements, with terms more than 12 months to be recognized as assets and liabilities
on the balance sheet. Recognition, measurement and presentation of expenses will depend on classification as a finance

August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, <I>Disclosure Update and Simplification</I>, amending
certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments
expanded the disclosure requirements on the analysis of stockholders&rsquo; equity for interim financial statements. Under the
amendments, an analysis of changes in each caption of stockholders&rsquo; equity presented in the balance sheet must be provided
in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of
each period for which a statement of operations is required to be filed. This final rule became effective on November 5,
2018. On September 25, 2018, the SEC released guidance advising that it will not object to a registrant adopting the requirement
to include changes in stockholders&rsquo; equity in the Form 10-Q for the first quarter beginning after the effective date of
the rule. The Company does not expect the adoption of SEC Release No. 33-10532 to have a material impact on its financial position,

warrant liability in the table above is composed of the fair value of a warrant to purchase shares of common stock that were issued
to the Company&rsquo;s placement agent in connection with the Series A Preferred offering (see Note 5). The fair value of the
warrant liability was determined based on significant inputs not observable in the market, which represents a Level 3 measurement
within the fair value hierarchy. The Company used the BSM, which incorporates assumptions and estimates, to value the warrant.
Estimates and assumptions impacting the fair value measurement include the fair value per share of the underlying shares of common
stock, the remaining contractual term of the warrant, risk-free interest rate, expected dividend yield and expected volatility
of the price of the underlying common stock. The Company determined the fair value per share of the underlying common stock by
taking into consideration the most recent sales of its preferred stock, results obtained from third-party valuations and additional
factors that are deemed relevant. The Company historically has been a private company and lacks company-specific historical
and implied volatility information of its common stock. Therefore, the Company estimates its expected stock volatility based on
the historical volatility of publicly traded peer companies for a term equal to the remaining contractual term of the warrant.
The risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to
the remaining contractual term of the warrant. The Company estimated a 0% expected dividend yield based on the fact that the Company
has never paid or declared dividends and does not intend to do so in the foreseeable future.</FONT></P>

In June 2017, the Company issued 6,685,082 Series A Preferred at a price of $3.00 per share and all shares remained outstanding
as of December 31, 2017 and September 30, 2018. The gross proceeds were $20,055 from the Series A Preferred stock offering.
The Series A Preferred stockholders or their permitted transferees, are entitled to rights with respect to the registration under
the Securities Act of 1933, as amended (the &ldquo;Securities Act&rdquo;), of their shares that are converted to common stock,

Series A Preferred automatically converted to common shares upon completion of the IPO in November 2018. The conversion share
calculation was based on the $3.00 initial issue price for the Series A Preferred plus any accrued but unpaid dividends and automatically
converted into shares of the Company&rsquo;s common stock using a stated divisor conversion price equal to 50% of the IPO price
to the public which was $6.00 per share. In accordance with relevant accounting literature, since the terms of the conversion
option did not permit the Company to compute the additional number of shares that it would need to issue upon conversion of the
Series A Preferred when the contingent event occurred, the Company recorded the beneficial conversion amount as a deemed dividend

the Series A Preferred offering are being ratably accreted as a deemed dividend using the effective interest method over its expected

May 2017, the Company issued a warrant to purchase 600,000 shares of its common stock to consultants for business strategy and
intellectual property advisory services. The warrant vested at issuance in May 2017 and has a $0.01 exercise price per warrant
share and expires five years from the date of issuance. The Company used the BSM to value the warrant and the fair value
at the date of issuance was $121 based on an expected term of five years, volatility of 85%, a risk-free interest rate of
1.8% and a 0% rate on expected dividends. The $121 amount for the consulting warrants was expensed as a component of the Company&rsquo;s
general and administrative expenses in May 2017.</FONT></P>

conjunction with the closing of the Series A Preferred offering in June 2017 (See Note 5), the Company issued a warrant
to purchase 649,409 shares of its common stock to the placement agent at an exercise price of $3.00 per share, provided, however,
upon the conversion of the Series A Preferred, the warrant shall adjust to entitle the holder to purchase shares of common stock
equal to 10.0% of the shares of common stock issuable upon conversion of the Series A Preferred (excluding 191,000 shares of
Series A Preferred that were purchased by insiders) and the exercise price shall adjust to the conversion price of the Series
A Preferred. This warrant vested at issuance in June 2017. The Company used the BSM to value the warrant and the fair value at
the date of issuance was $479. The number of common shares issuable upon the exercise of this warrant was not fixed
as it could vary by a factor of 1.000 to 1.333 common shares per warrant share in accordance with the IPO price, and the
Company considered the warrant to be a derivative instrument. The $479 amount was recorded as a component of the issuance costs
for the Series A Preferred in June 2017. As of December 31, 2017, the fair value of the warrant was $520 and the $41 increase
in value during 2017 was recorded as a component of other income and expense.</FONT></P>

value of Common Stock &mdash; Prior to the Company&rsquo;s IPO in November 2018, the fair value of the shares of common stock
underlying the stock-based awards was determined by the board of directors, with input from management. Because there was no public
market for the Company&rsquo;s common stock, the board of directors determined the fair value of the common stock on the grant-date
of the stock-based award by considering a number of objective and subjective factors, including enterprise valuations of the Company&rsquo;s
common stock performed by an unrelated third-party specialist, valuations of comparable companies, sales of the Company&rsquo;s
convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of the
Company&rsquo;s capital stock, and general and industry-specific economic outlook. The board of directors intended all options
granted to be exercisable at a price per share not less than the estimated per share fair value of common stock underlying those
options on the date of grant.</FONT></P>

was issued 3,500,000 shares of the Company&rsquo;s common stock at the formation of the Company at the $0.001 par value per share
price as the paid-in-capital contribution from Imprimis. The Company and Imprimis signed licensing agreements for two products
developed by Imprimis whereby Imprimis assigned the product rights to the Company. The Company will pay Imprimis a $50 milestone
payment upon patent approval for each product and a royalty fee at a rate of six percent on the net sales of those two products.
On December 26, 2017, one of the products had its patent approved and a $50 milestone fee was recognized as R&amp;D expense by
the Company in 2017 and paid to Imprimis in January 2018. In July 2018, the Company determined the patent-approved product was
not viable for its portfolio of product opportunities and Imprimis paid the Company $50 to cancel the licensing agreement for
the one product and retain the product rights at Imprimis.</FONT></P>

were formed in April 2017 as a specialty pharmaceutical company focused on developing and commercializing innovative pharmaceutical

product candidates, the submission of an NDA for our initial product candidate and preliminary discussions with the FDA concerning
the regulatory pathway for certain additional product candidates. We have not commenced revenue-producing operations and, under

corporate strategy is to pursue what we perceive to be low-risk candidates where existing published literature, historical clinical
trials, or physician usage has established safety and/or efficacy of the molecule, thereby reducing the incremental clinical burden
required for us to bring the product to patients. We intend to pursue product candidates that require a single small Phase 3 trial,
a bio-equivalence trial, or literature-based filings. Prior to initiating significant development activities on a product candidate,
we typically meet with the FDA to establish a defined clinical and regulatory path to approval.</FONT></P>

of September 30, 2018, we had total assets of $7.5 million and working capital of $5.6 million. We capitalized our operations
primarily from the June 2017 private placement of approximately $20.1 million of Series A preferred stock, par value $0.001 (the
&ldquo;Series A Preferred&rdquo;). Our Series A Preferred  accumulated dividends at the rate of 6% per annum
and those shares of stock plus all accrued but unpaid dividends automatically converted into shares of our common stock concurrent
with the Company&rsquo;s initial public offering in November 2018 (the &ldquo;IPO&rdquo;), at the conversion price of 50% of the
IPO price. The IPO provided us with net proceeds of $22.6 million which we believe should be sufficient for at least the next
24 months of our operations including through securing regulatory approval and commencement of commercial sales for at least one
product candidate. We do not anticipate requiring additional funding after that point.</FONT></P>

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

account for stock-based compensation under the provisions of the Financial Accounting Standards Board (the &ldquo;FASB&rdquo;)
Accounting Standards Codification (&ldquo;ASC&rdquo;) - 718 Compensation &ndash; Stock Compensation. The guidance under
ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant for employees
and directors and record expense over the related service periods, which are generally the vesting period of the equity awards.
Awards for consultants are accounted for under ASC 505-50 - Equity Based Payments to Non-Employees. Compensation expense is recognized
over the period during which services are rendered by such consultants and non-employees until completed. At the end of each financial
reporting period prior to completion of the service, the fair value of these awards is remeasured using the then-current fair
value of our common stock and updated assumption inputs in the Black-Scholes option-pricing model (&ldquo;BSM&rdquo;).</FONT></P>

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

clinical trial activities, manufacturing and control-related activities and regulatory costs. R&amp;D expenses are charged to
operations as incurred. We review and accrue R&amp;D expenses based on services performed and rely upon estimates of those costs
applicable to the stage of completion of each project. Significant judgments and estimates are made in determining the accrued

estimate the fair value of certain warrants at each reporting period using Level 3 inputs. The estimates in valuation models are
based, in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants,
the risk-free interest rate and the exercise price of the warrants, and could differ materially in the future. Changes in the
fair value of the warrant liability during the period are recorded as a component of other income (expense). We will continue
to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value until the earlier
of the exercise or expiration of the applicable warrants or when the number of shares issuable upon exercise of these warrants
is fixed which occurred with our IPO in November 2018</FONT></P>

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

limitation, (i) providing an auditor&rsquo;s attestation report on our system of internal controls over financial reporting pursuant
to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by the Public Company
Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor&rsquo;s report providing additional
information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging
growth company until the earlier to occur of (1) the last day of the fiscal year (a) December 31, 2023, which is the end of the
fiscal year following the fifth anniversary of the completion of our IPO, (b) in which we have total annual gross revenues of
at least $1.07 billion or (c) in which we are deemed to be a &ldquo;large accelerated filer&rdquo; under the rules of the SEC,
which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th,

primary objective of our investment activities is to preserve capital. We do not utilize hedging contracts or similar instruments.
We are exposed to certain market risks relating primarily to interest rate risk on our cash and cash equivalents and risks relating
to the financial viability of the institutions which hold our capital and through which we have invested our funds. We manage
such risks by investing in short-term, liquid, highly-rated instruments. As of September 30, 2018, our cash equivalents and investments
are invested exclusively in money market funds. We do not believe we have any material exposure to interest rate risk due to the
extremely low interest rate environment and the short duration of the invested funds we hold. Declines in interest rates would
reduce our investment income but would not have a material effect on our financial condition or results of operations. We do not
currently have exposure to foreign currency risk.</FONT></P>

does not expect that our internal control over financial reporting will prevent or detect all errors and all fraud. A control
system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of
the control systems are met. Further, the design of a control system must reflect the fact that there are resource constraints,
and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a cost-effective
control system, no evaluation of internal control over financial reporting 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 or will be detected.</FONT></P>

operations have consisted of the preliminary formulation, testing and development of our initial product candidates. Our limited
operating history makes it difficult for potential investors to evaluate our initial product candidates or our prospective operations.
As an early stage company, we are subject to all the risks inherent in the initial organization, financing, expenditures, complications
and delays in a new business. Further, biopharmaceutical product development is a highly speculative undertaking, involves a substantial
degree of risk and is a capital-intensive business. Accordingly, you should consider our prospects in light of the costs, uncertainties,
delays and difficulties frequently encountered by companies in the early stages of development, especially clinical-stage biopharmaceutical

limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such
amounts.</FONT></P>

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

product candidates are in the early stages of clinical development, and we do not generate revenues from any FDA approved drug

or foreign equivalent to the FDA or international regulatory authorities for our CT-100 product candidate, and may be required
to submit INDs for our other product candidates, seeking approval to initiate our clinical trials in humans in the United States
or other countries yet to be determined. We plan on submitting our clinical trial protocols and receive approvals from the FDA
and international regulatory authorities before we commence any clinical trials. We may not be successful in obtaining acceptance
from the FDA or comparable foreign regulatory authorities to start our clinical trials. If we do not obtain such acceptance, the
time in which we expect to commence clinical programs for any product candidate will be extended and such extension will increase
our expenses and increase our need for additional capital. Moreover, there is no guarantee that our clinical trials will be successful
or that we will continue clinical development in support of an approval from the FDA or comparable foreign regulatory authorities
for any indication. We note that most product candidates never reach the clinical development stage and even those that do commence
clinical development have only a small chance of successfully completing clinical development and gaining regulatory approval.
Therefore, our business currently depends entirely on the successful development, regulatory approval and commercialization of
our product candidates, which may never occur.</FONT></P>

biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change.
We have existing competitors and potential new competitors in a number of jurisdictions, many of which have or will have substantially
greater name recognition, commercial infrastructures and financial, technical and personnel resources than we have. Established
competitors may invest heavily to quickly discover and develop novel compounds that could make any of our product candidates obsolete
or uneconomical. In addition, mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more
resources being concentrated among a smaller number of our competitors, potentially reducing or eliminating our commercial opportunity.
Furthermore, such potential competitors may enter the market before us, and their products may be designed to circumvent our pending
patent applications and any patents we may receive. They may also challenge, narrow or invalidate any granted patents or our patent
applications, and such patents and patent applications may fail to provide adequate protection for our product candidates. Any
new product that competes with an approved product may need to demonstrate compelling advantages in efficacy, cost, convenience,
tolerability and safety to be commercially successful. Other competitive factors, including generic competition, could force us
to lower prices or could result in reduced sales. In addition, new products developed by others could emerge as competitors to
our product candidates. If we are not able to compete effectively against our current and future competitors, our business will
not grow and our financial condition and operations will suffer.</FONT></P>

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

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

hold one patent application for our CT-100 product candidate and one provisional patent application for our DS-300 product
candidate. In addition, we expect that we or our development partner will file a patent application covering our ET-103
product candidate. Other than any protection that may be afforded by the issuance of a patent with respect to such
applications, of which there can be no assurance, we do not believe that any of our current product candidates are eligible
for patent protection or the market and data exclusivity provisions under the FDCA. The FDCA provides three years of
marketing exclusivity for an NDA, 505(b)(2) NDA, or supplement to an existing NDA or 505(b)(2) NDA if new clinical
investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA
to be essential to the approval of the application, (e.g, for new indications, dosages, strengths or dosage forms of an
existing drug). Many of our competitors have significantly greater financial, manufacturing, marketing, drug development,
technical and human resources than we do. As a result, many of our competitors have the ability to bring a product candidate
to market more rapidly than we can and depending on the nature of their product candidate they could substantially delay the
introduction of our product candidate into the market if their product qualifies for the market and data exclusivity
provisions under the FDCA. In order to preserve any competitive advantage, we will, at times, make the decision to pursue a
product candidate for which we will not disclose the API, dosage or reference drug until such time as we believe that any
competitive advantage would not be materially compromised by public disclosure of such information, which in some cases may
be as late as our receipt of marketing approval from the FDA. Our business currently depends on our ability to bring our
product candidates to market in a manner that preserves our perceived competitive advantage and any loss of that competitive
advantage could negatively impact our business, results of operations and stock price.</FONT></P>

testing is expensive, is difficult to design and implement, can take many years to complete and is uncertain as to outcome. Success
in early phases of pre-clinical and clinical trials does not ensure that later clinical trials will be successful, and interim
results of a clinical trial do not necessarily predict final results. A failure of one or more of our clinical trials can occur
at any stage of testing. We may experience numerous unforeseen events during, or as a result of, the clinical trial process that
could delay or prevent our ability to receive regulatory approval or commercialize our product candidates. The research, testing,
manufacturing, labeling, packaging, storage, approval, sale, marketing, advertising and promotion, pricing, export, import and
distribution of drug products are subject to extensive regulation by the FDA and other regulatory authorities in the United States
and other countries, which regulations differ from country to country. We are not permitted to market our product candidates as
prescription pharmaceutical products in the United States until we receive approval of an NDA from the FDA, or in any foreign
countries until we receive the requisite approval from such countries. In the United States, the FDA generally requires the completion
of clinical trials of each drug to establish its safety and efficacy and extensive pharmaceutical development to ensure its quality
before an NDA is approved. Regulatory authorities in other jurisdictions impose similar requirements. Of the large number of drugs
in development, only a small percentage result in the submission of an NDA to the FDA and even fewer are eventually approved for
commercialization. We have submitted an ANDA for our EM-100 product candidate and an NDA to the FDA for our DS-300 product candidate,
however, there can be no assurance our NDA will be approved by the FDA. If our development efforts for our product candidates,
including regulatory approval, are not successful for their planned indications, or if adequate demand for our product candidates
is not generated, our business will be materially adversely affected.</FONT></P>

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

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

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

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

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

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

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

one or more additional clinical studies or measurements to support the change from the branded reference drug, which could be
time consuming and could substantially delay our achievement of regulatory approvals for such product candidates. The FDA may
also reject our future 505(b)(2) submissions and require us to file such submissions under Section 505(b)(1) of the FDCA, which

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

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

FDA as reflected in the product&rsquo;s approved labeling. If we receive marketing approval for our product candidates, physicians
may nevertheless legally prescribe our products to their patients in a manner that is inconsistent with the approved label. If
we are found to have promoted such off-label uses, we may become subject to significant liability and government fines. The FDA
and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is
found to have improperly promoted off-label uses may be subject to significant sanctions. The federal government has levied large
civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in
off-label promotion. The FDA has also requested that companies enter into consent decrees of permanent injunctions under which
specified promotional conduct is changed or curtailed.</FONT></P>

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

the United States, the Medicare Modernization Act (&ldquo;MMA&rdquo;) changed the way Medicare covers and pays for pharmaceutical
products. The legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology
based on average sales prices for drugs. In addition, this legislation authorized Medicare Part D prescription drug plans to use
formularies where they can limit the number of drugs that will be covered in any therapeutic class. As a result of this legislation
and the expansion of federal coverage of drug products, we expect that there will be additional pressure to contain and reduce
costs. These cost reduction initiatives and other provisions of this legislation could decrease the coverage and price that we
receive for our product candidates and could seriously harm our business. While the MMA applies only to drug benefits for Medicare
beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement
rates, and any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from private
payors.</FONT></P>

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

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

January 2017, President Trump has signed two executive orders and other directives designed to delay, circumvent or loosen certain
requirements mandated by the Health Care Reform Law. Concurrently, Congress has considered legislation that would repeal or repeal
and replace all or part of the Health Care Reform Law. While Congress has not passed repeal legislation, the Tax Cuts and Jobs
Act of 2017 includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by
the Health Care Reform Law on certain individuals who fail to maintain qualifying health coverage for all or part of a year that
is commonly referred to as the &ldquo;individual mandate.&rdquo; Additionally, on January 22, 2018, President Trump signed a continuing
resolution on appropriations for fiscal year 2018 that delayed the implementation of certain Health Care Reform Law-mandated fees,
including the so-called &ldquo;Cadillac&rdquo; tax on certain high cost employer-sponsored insurance plans, the annual fee imposed

Congress may consider other legislation to repeal or replace elements of the Health Care Reform Law. We cannot predict the impact
on our business of changes to current laws and regulations. However, any changes that lower reimbursements for products for which
we may obtain regulatory approval, or that impose administrative and financial burdens on us, could adversely affect our business.</FONT></P>

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

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

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

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

the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist
if there is a challenge to such ownership without regard to the merits of the challenge and industry and market conditions generally.
Potential third parties may also consider alternative product candidates or technologies for similar indications that may be available

third parties. We may not be able to negotiate agreements on a timely basis, on acceptable terms or at all. If we are unable to
do so, we may have to curtail the development of the product candidate, reduce or delay its development program, delay its potential
commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development
or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization
activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all.
If we do not have sufficient funds, we may not be able to further develop our product candidate or bring it to market and generate
product revenue.</FONT></P>

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

development costs for any of our product candidates will increase if we have delays in testing or approval or if we need to perform

of that study. If we experience delays in completion of, or if we, the FDA or other regulatory authorities, the IRB, or other

candidates, its commercial prospects may be materially harmed and our ability to generate product revenues will be delayed. Any
delays in completing our clinical trials will increase our costs, slow down our development and approval process and jeopardize
our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition
and prospects significantly. In addition, many of the factors that cause, or lead to, termination or suspension of, or a delay
in the commencement or completion of, clinical studies may also ultimately lead to the denial of regulatory approval of our product
candidates. In addition, if one or more clinical studies are delayed, our competitors may be able to bring products to market

testing of drug product candidates is expensive and can take many years to complete, and its outcome is inherently uncertain.
Failure can occur at any time during the clinical trial process. The results of pre-clinical studies and early clinical trials
may not be predictive of the results of later-stage clinical trials. We cannot assure you that the FDA or comparable foreign regulatory
authorities will view the results as we do or that any future trials of any of our product candidates will achieve positive results.
Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed
through pre-clinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have suffered
significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising
results in earlier trials. Any future clinical trial results for our product candidates may not be successful.</FONT></P>

addition, a number of factors could contribute to a lack of favorable safety and efficacy results for any of our product candidates.
For example, such trials could result in increased variability due to varying site characteristics, such as local standards of
care, differences in evaluation period and surgical technique, and due to varying patient characteristics including demographic
factors and health status.</FONT></P>

have not conducted clinical trials for any of our product candidates, other than a bioequivalence trial for one product candidate,
and we may be delayed in commercializing or fail to find success in these trials. Further, the results of any clinical trial may
not be predictive of future trial results. Positive results in preclinical testing and early clinical trials do not ensure that
later clinical trials will be successful. A number of pharmaceutical companies have suffered significant setbacks in clinical
trials, including in Phase 3, after promising results in preclinical testing and early clinical trials. These setbacks have included
negative safety and efficacy observations in later clinical trials, including previously unreported adverse events.</FONT></P>

in multiple clinics and medical centers across a number of different countries. Before commencing Phase 3 clinical trials in the
United States, we will also need to agree on a protocol with the FDA.</FONT></P>

we conduct additional clinical, nonclinical, manufacturing, validation or drug product quality studies and submit that data before
considering or reconsidering any NDA or similar foreign regulatory application we may submit. Depending on the extent of these
additional studies, approval of any applications that we submit may be significantly delayed or may require us to expend more
resources than we have available. It is also possible that additional studies we conduct may not be considered sufficient by the

of royalties and other payment due under the agreements. Termination of these agreements could prevent us from marketing some

unfavorable resolution of such a dispute could lead to an increase in the royalties payable pursuant to the agreement. If the

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

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

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

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

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

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

on decisions by the U.S. Congress, the federal courts, the U.S. PTO, or similar authorities in foreign jurisdictions, the laws

characterized by frequent litigation regarding patent and other intellectual property rights. Identification of third-party patent
rights that may be relevant to our proprietary technology is difficult because patent searching is imperfect due to differences
in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. Additionally,
because patent applications are maintained in secrecy until the application is published, we may be unaware of third-party patents
that may be infringed by commercialization of any of our product candidates or any future product candidate. There may be certain

In addition, for the period&#13;from April 27, 2017 (inception) to December 31, 2017 and for the nine months ended September 30, 2018, the Company had net cash&#13;used in operating activities of $4,718 and $6,371, respectively.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;To date, t&lt;font style="background-color: white"&gt;he&#13;Company has not generated any revenues and does not anticipate generating any revenues unless and until it successfully completes&#13;development and obtains regulatory approval for one of its product candidates. &lt;/font&gt;As of September 30, 2018, the Company had&#13;an accumulated deficit of $19,806 and has incurred negative cash flow from operating activities since its inception. The Company&#13;currently believes its existing cash and cash equivalents, together with the net cash proceeds received from the closing of its&#13;IPO on November 15, 2018 of $22,603 (see Note 12), will be sufficient to fund its operating expenses and capital expenditure requirements&#13;for at least the next 24 months from the date of issuance of these financial statements. This estimate is based on the Company&amp;#8217;s&#13;current assumptions, including assumptions relating to its ability to manage its spending. The Company could use its available&#13;capital resources sooner than currently expected. Accordingly, t&lt;font style="background-color: white"&gt;he Company could seek to&#13;obtain additional capital through equity financings, the sale of debt or other arrangements. However, there can be no assurance&#13;that the Company will be able to raise additional capital if needed or under acceptable terms, if at all. The sale of additional&#13;equity may dilute existing stockholders and newly issued shares may contain senior rights and preferences compared to currently&#13;outstanding common shares. Issued debt securities may contain covenants and limit the Company&amp;#8217;s ability to pay dividends&#13;or make other distributions to stockholders. If the Company is delayed in completing its product development and obtaining regulatory&#13;approval for its product candidates and is unable to obtain such additional financing, operations would need to be scaled back&#13;or discontinued.&lt;/font&gt;&lt;/p&gt;</us-gaap:LiquidationBasisOfAccountingTextBlock>

The results for the periods ended September 30, 2018 are not necessarily indicative&#13;of results to be expected for the year ending December 31, 2018, any other interim periods or any future year or period.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Use of Estimates&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The preparation of financial&#13;statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets&#13;and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed financial statements and the&#13;reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these&#13;condensed financial statements include, but are not limited to, the accrual of research and development expenses and the valuation&#13;of common stock, stock options, warrants and derivative instruments. Estimates are periodically reviewed in light of changes in&#13;circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known.

The Company&amp;#8217;s chief operating decision-maker is the Chief Executive Officer (&amp;#8220;CEO&amp;#8221;), who evaluates&#13;the Company as a single operating segment.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Cash and Cash Equivalents&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Company considers&#13;all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash equivalents&#13;are held in U.S. financial institutions. Cash equivalents consist of an interest-bearing checking account. From time to time, amounts&#13;deposited exceed federally insured limits. The Company believes the associated credit risk to be minimal.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Deferred Offering Costs&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Company capitalizes&#13;certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings&#13;as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded&#13;in stockholders&amp;#8217; deficit as a reduction of proceeds generated as a result of the offering. Should the planned equity financing&#13;be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the statements of operations.&#13;The Company recorded deferred offering costs of $0 and $397 as of December 31, 2017 and September 30, 2018, respectively, which&#13;is included in other long-term assets on the accompanying condensed balance sheet.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Classification and Accretion of Redeemable&#13;Convertible Preferred Stock&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Company has classified&#13;the Series A Preferred outside of stockholders&amp;#8217; equity (deficit) because the shares contain certain redemption features that&#13;are not solely within the control of the Company.

Internal R&amp;#38;D activity&#13;expenses include salaries, benefits and stock-based compensation and other costs to support the Company&amp;#8217;s R&amp;#38;D operations.&#13;External contracted services include product development efforts including certain product licensor milestone payments, clinical&#13;trial activities, manufacturing and control-related activities and regulatory costs. R&amp;#38;D expenses are charged to operations&#13;as incurred. The Company reviews and accrues R&amp;#38;D expenses based on services performed and relies upon estimates of those costs&#13;applicable to the stage of completion of each project. Significant judgments and estimates are made in determining the accrued&#13;balances at the end of any reporting period. Actual results could differ from the Company&amp;#8217;s estimates.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;Upfront payments and milestone&#13;payments made for the licensing of technology are expensed as R&amp;#38;D in the period in which they are incurred.

Diluted net loss per share is computed by dividing the net loss attributable to common stockholders&#13;for the period by the weighted average number of common and common equivalent shares, such as Series A Preferred, unvested restricted&#13;stock, stock options and warrants, outstanding during the period. Common stock equivalents are excluded from the computation where&#13;their inclusion would be anti-dilutive. No such adjustments were made for 2017 or 2018 as the Company reported a net loss for the&#13;periods ended September 30, 2017 and 2018 as including the effects of common stock equivalents in the diluted EPS calculation would&#13;have been antidilutive (See Note 9).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Warrant Liability&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Company estimates&#13;the fair value of certain warrants at each reporting period using Level 3 inputs. The estimates in valuation models are based,&#13;in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the&#13;risk-free interest rate and the exercise price of the warrants, and could differ materially in the future. Changes in the fair&#13;value of the warrant liability during the period are recorded as a component of other income (expense). The Company will continue&#13;to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value until the earlier&#13;of the exercise or expiration of the applicable warrants, or when the number of shares issuable upon exercise of these warrants&#13;is fixed which occurred with the Company&amp;#8217;s IPO in November 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Stock-Based Compensation&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Company accounts for&#13;stock-based compensation under the provisions of the Financial Accounting Standards Board (the &amp;#8220;FASB&amp;#8221;) Accounting Standards&#13;Codification (&amp;#8220;ASC&amp;#8221;) &amp;#8212; 718 Compensation &amp;#8212; Stock Compensation. The guidance under ASC 718 requires companies&#13;to estimate the fair value of the stock-based compensation awards on the date of grant for employees and directors and record expense&#13;over the related service periods, which are generally the vesting period of the equity awards. Awards for consultants are accounted&#13;for under ASC 505-50 &amp;#8212; Equity Based Payments to Non-Employees. Compensation expense is recognized over the period during&#13;which services are rendered by such consultants and non-employees until completed. At the end of each financial reporting period&#13;prior to completion of the service, the fair value of these awards is remeasured using the then-current fair value of the Company&amp;#8217;s&#13;common stock and updated assumption inputs in the Black-Scholes-Merton option-pricing model (&amp;#8220;BSM&amp;#8221;).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Company estimates&#13;the fair value of stock-based option awards to its employees and directors using the BSM. The BSM requires the input of subjective&#13;assumptions, including the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of&#13;the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined from the implied&#13;yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options or warrants.&#13;Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options&#13;granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies&amp;#8217;&#13;historical volatility, which management believes represents the most accurate basis for estimating expected future volatility under&#13;the current conditions. The Company accounts for forfeitures as they occur.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Fair Value Measurements&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;We measure certain of&#13;our assets and liabilities at fair value. Fair value represents the price that would be received to sell an asset or paid to transfer&#13;a liability in an orderly transaction between market participants at the measurement date. Fair value accounting requires characterization&#13;of the inputs used to measure fair value into a three-level fair value hierarchy as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;b&gt;&lt;i&gt;Level 1&lt;/i&gt;&lt;/b&gt;&#13;&amp;#8212; Inputs based on quoted prices in active markets for identical assets or liabilities. An active market is a market in which&#13;transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;b&gt;&lt;i&gt;Level 2 &lt;/i&gt;&lt;/b&gt;&amp;#8212;&#13;Observable inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based&#13;on market data obtained from sources independent from the entity.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;b&gt;&lt;i&gt;Level 3 &lt;/i&gt;&lt;/b&gt;&amp;#8212;&#13;Unobservable inputs that reflect the entity&amp;#8217;s own assumptions about the assumptions market participants would use in pricing&#13;the asset or liability developed based on the best information available.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;Fair value measurements&#13;are classified based on the lowest level of input that is significant to the measurement. The Company&amp;#8217;s assessment of the&#13;significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the assets&#13;and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values stated below takes&#13;into account the market for the Company&amp;#8217;s financials, assets and liabilities, the associated credit risk and other factors&#13;as required. The Company considers active markets as those in which transactions for the assets or liabilities occur in sufficient&#13;frequency and volume to provide pricing information on an ongoing basis.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The carrying amounts of&#13;cash and cash equivalents, accounts payable and accrued liabilities approximate their fair values due to the short-term maturities&#13;of these instruments.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The fair values of the&#13;Company&amp;#8217;s warrant liability at inception and for subsequent mark-to-market fair value measurements are based on management&amp;#8217;s&#13;valuation model and expectations with respect to the method and timing of settlement. The Company has determined that the warrant&#13;liability fair values are classified as Level 3 measurements within the fair value hierarchy.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Impact of New Accounting Pronouncements&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&amp;#160;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;In February 2016, the&#13;FASB issued ASU 2016-02 (Topic 842) &amp;#8211; Leases, which requires the lease rights and obligations arising from lease contracts,&#13;including existing and new arrangements, with terms more than 12 months to be recognized as assets and liabilities on the balance&#13;sheet. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The&#13;amendments also require certain quantitative and qualitative disclosures about leasing arrangements. ASU 2016-02 is effective for&#13;reporting periods beginning after December 15, 2018 with early adoption permitted. While the Company is still evaluating ASU 2016-02,&#13;the Company expects the adoption of ASU 2016-02 will not have a material effect on the Company&amp;#8217;s financial condition from&#13;the recognition of the lease rights and obligations as assets and liabilities. The Company is currently evaluating ASU 2016-02&#13;to determine the effect on the Company&amp;#8217;s results of operations and cash flows.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;In June 2018, the FASB&#13;issued ASU 2018-07, Compensation &amp;#8212; Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting,&#13;which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies&#13;to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor&amp;#8217;s&#13;own operations by issuing share-based payment awards. ASU 2018-07 will be effective for financial statements issued for fiscal&#13;years beginning after December 15, 2018, and interim periods within those fiscal years with early adoption permitted (but no sooner&#13;than the adoption of Topic 606). The Company is currently evaluating ASU 2018-07 to determine the effect on the Company&amp;#8217;s&#13;financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;In August 2018, the SEC&#13;adopted the final rule under SEC Release No. 33-10532, &lt;i&gt;Disclosure Update and Simplification&lt;/i&gt;, amending certain disclosure&#13;requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure&#13;requirements on the analysis of stockholders&amp;#8217; equity for interim financial statements. Under the amendments, an analysis&#13;of changes in each caption of stockholders&amp;#8217; equity presented in the balance sheet must be provided in a note or separate&#13;statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which&#13;a statement of operations is required to be filed. This final rule became effective on November 5, 2018. On September 25, 2018,&#13;the SEC released guidance advising that it will not object to a registrant adopting the requirement to include changes in stockholders&amp;#8217;&#13;equity in the Form 10-Q for the first quarter beginning after the effective date of the rule. The Company does not expect the&#13;adoption of SEC Release No. 33-10532 to have a material impact on its financial position, results of operations and related disclosures.&#13;The Company anticipates adopting SEC Release No. 33-10532 in its Form 10-Q filing for the quarter ending March 31, 2019.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The fair value of the warrant liability was determined&#13;based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy.&#13;The Company used the BSM, which incorporates assumptions and estimates, to value the warrant. Estimates and assumptions impacting&#13;the fair value measurement include the fair value per share of the underlying shares of common stock, the remaining contractual&#13;term of the warrant, risk-free interest rate, expected dividend yield and expected volatility of the price of the underlying common&#13;stock. The Company determined the fair value per share of the underlying common stock by taking into consideration the most recent&#13;sales of its preferred stock, results obtained from third-party valuations and additional factors that are deemed relevant. The&#13;Company historically has been a private company and lacks company-specific historical and implied volatility information of its&#13;common stock. Therefore, the Company estimates its expected stock volatility based on the historical volatility of publicly traded&#13;peer companies for a term equal to the remaining contractual term of the warrant. The risk-free interest rate is determined by&#13;reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining contractual term of the warrant.&#13;The Company estimated a 0% expected dividend yield based on the fact that the Company has never paid or declared dividends and&#13;does not intend to do so in the foreseeable future.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The Company has granted RSAs, stock&#13;options and restricted stock units (&amp;#8220;RSUs&amp;#8221;) for its common stock under the Plan as detailed in the tables below. There&#13;were 976,020 shares available for future issuance under the Plan as of September 30, 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;Shares that are expired,&#13;terminated, surrendered or canceled without having been fully exercised will be available for future awards under the Plan. The&#13;exercise price for stock options granted is not less than the fair value of common shares as determined by the board of directors&#13;as of the date of grant. The Company&amp;#8217;s board of directors values the Company&amp;#8217;s common stock, taking into consideration&#13;its most recently available valuation of common stock performed by third parties as well as additional factors which may have changed&#13;since the date of the most recent contemporaneous valuation through the date of grant.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;On January 1, 2018, the&#13;Company issued 54,745 restricted shares of its common stock to each of its four outside directors (218,980 total shares). The restricted&#13;shares issued to the outside directors vest 25% at each quarter-end in 2018 and will be 100% vested at December 31, 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;To date, all stock options&#13;issued have been non-qualified stock options and the exercise prices were set at the fair value for the shares at the dates of&#13;grant. Options typically have a ten-year life except for options to purchase 50,000 shares of the Company&amp;#8217;s common stock&#13;granted to product consultants that expire within five years if the Company is not able to file certain product submissions to&#13;the FDA prior to the five-year expiration date. Furthermore, these option awards to the Company&amp;#8217;s product consultants do&#13;not vest unless certain product submissions are made to the FDA, and accordingly, the Company has not recorded any expense for&#13;these contingently vesting option awards to its product consultants.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;For the three months ended&#13;September 30, 2018 and 2017, the Company&amp;#8217;s total stock-based compensation expense was $165 and $604, respectively.

for estimating the expected term of options granted to employees&#13;and directors, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of&#13;the option (generally 10 years). The expected term of options granted to non-employees equals the contractual life of the options.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;Expected Volatility &amp;#8212;&#13;Due to the Company&amp;#8217;s limited operating history and a lack of Company-specific historical and implied volatility data, the&#13;Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly&#13;traded. The historical volatility data was computed using the daily closing prices for the selected companies&amp;#8217; shares during&#13;the equivalent period of the calculated expected term of the stock-based awards.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;Risk-Free Interest Rate&#13;&amp;#8212; The risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of&#13;the Company&amp;#8217;s stock options.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;Expected Dividend &amp;#8212;&#13;The Company has not issued any dividends in its history and does not expect to issue dividends over the life of the options and&#13;therefore has estimated the dividend yield to be zero.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;Fair value of Common Stock&#13;&amp;#8212; Prior to the Company&amp;#8217;s IPO in November 2018, the fair value of the shares of common stock underlying the stock-based&#13;awards was determined by the board of directors, with input from management. Because there was no public market for the Company&amp;#8217;s&#13;common stock, the board of directors determined the fair value of the common stock on the grant-date of the stock-based award by&#13;considering a number of objective and subjective factors, including enterprise valuations of the Company&amp;#8217;s common stock performed&#13;by an unrelated third-party specialist, valuations of comparable companies, sales of the Company&amp;#8217;s convertible preferred&#13;stock to unrelated third parties, operating and financial performance, the lack of liquidity of the Company&amp;#8217;s capital stock,&#13;and general and industry-specific economic outlook. The board of directors intended all options granted to be exercisable at a&#13;price per share not less than the estimated per share fair value of common stock underlying those options on the date of grant.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.25in"&gt;A summary of activity for RSAs and RSUs is&#13;as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td style="border-bottom: black 1.5pt solid"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;Restricted Stock Awards&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td colspan="2" style="border-bottom: black 1.5pt solid; text-align: center"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;Number of shares&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: #CCEEFF"&gt;&#13;    &lt;td style="width: 82%"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;Unvested as of December 31, 2017&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 15%; text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;2,500,000&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: white"&gt;&#13;    &lt;td&gt;&lt;font style="font-size: 10pt"&gt;Issued&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;218,980&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: #CCEEFF"&gt;&#13;    &lt;td&gt;&lt;font style="font-size: 10pt"&gt;Vested&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;(2,164,235&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&lt;font style="font-size: 10pt"&gt;)&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: white"&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&lt;font style="font-size: 10pt"&gt;Forfeited/Cancelled&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 1.5pt solid"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 1.5pt solid; text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;&amp;#8212;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom; background-color: #CCEEFF"&gt;&#13;    &lt;td style="padding-bottom: 2.5pt"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;Unvested as of September 30, 2018&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 2.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 2.25pt double"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="border-bottom: black 2.25pt double; text-align: right"&gt;&lt;font style="font-size: 10pt"&gt;&lt;b&gt;554,745&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 2.5pt"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The weighted average grant&#13;date fair value of the RSAs issued was $1.37 during the nine months ended September 30, 2018.

The Company and Imprimis signed licensing agreements for two products developed by Imprimis whereby&#13;Imprimis assigned the product rights to the Company. The Company will pay Imprimis a $50 milestone payment upon patent approval&#13;for each product and a royalty fee at a rate of six percent on the net sales of those two products. On December 26, 2017, one of&#13;the products had its patent approved and a $50 milestone fee was recognized as R&amp;#38;D expense by the Company in 2017 and paid&#13;to Imprimis in January 2018.

In June 2017,&#13;the Company issued 6,685,082 Series A Preferred at a price of $3.00 per share and all shares remained outstanding as of December&#13;31, 2017 and September 30, 2018. The gross proceeds were $20,055 from the Series A Preferred stock offering. The Series A Preferred&#13;stockholders or their permitted transferees, are entitled to rights with respect to the registration under the Securities Act of&#13;1933, as amended (the &amp;#8220;Securities Act&amp;#8221;), of their shares that are converted to common stock, including demand registration&#13;rights and piggyback registration rights. These rights are provided under the terms of a registration rights agreement between&#13;the Company and the investors.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;As of December 31, 2017,&#13;the liquidation value of the mezzanine Series A Preferred was $20,698, which consisted of the issuance amount of $20,055 plus accrued&#13;dividends of $643. As of September 30, 2018, the liquidation value of the mezzanine Series A Preferred was $21,598, which consisted&#13;of the issuance amount of $20,055 plus accrued dividends of $1,543.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Series A Preferred&#13;automatically converted to common shares upon completion of the IPO in November 2018. The conversion share calculation was based&#13;on the $3.00 initial issue price for the Series A Preferred plus any accrued but unpaid dividends and automatically converted into&#13;shares of the Company&amp;#8217;s common stock using a stated divisor conversion price equal to 50% of the IPO price to the public&#13;which was $6.00 per share. In accordance with relevant accounting literature, since the terms of the conversion option did not&#13;permit the Company to compute the additional number of shares that it would need to issue upon conversion of the Series A Preferred&#13;when the contingent event occurred, the Company recorded the beneficial conversion amount as a deemed dividend at the date of the&#13;IPO in November 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;As a result of the Series&#13;A Preferred having a possible cash redemption feature in the event that an IPO or alternate financing was not available by December&#13;31, 2018, the Series A Preferred is classified as temporary equity and not included as part of Company&amp;#8217;s stockholders&amp;#8217;&#13;deficit. In accordance with that classification, the $2,534 of issuance costs associated with the Series A Preferred offering are&#13;being ratably accreted as a deemed dividend using the effective interest method over its expected term.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif;

The Company used the BSM to value the warrant and the fair value at the date of issuance was $121&#13;based on an expected term of five years, volatility of 85%, a risk-free interest rate of 1.8% and a 0% rate on expected dividends.&#13;The $121 amount for the consulting warrants was expensed as a component of the Company&amp;#8217;s general and administrative expenses&#13;in May 2017.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;In conjunction with the&#13;closing of the Series A Preferred offering in June 2017 (See Note 5), the Company issued a warrant to purchase 649,409 shares of&#13;its common stock to the placement agent at an exercise price of $3.00 per share, provided, however, upon the conversion of the&#13;Series A Preferred, the warrant shall adjust to entitle the holder to purchase shares of common stock equal to 10.0% of the shares&#13;of common stock issuable upon conversion of the Series A Preferred (excluding 191,000 shares of Series A Preferred that were purchased&#13;by insiders) and the exercise price shall adjust to the conversion price of the Series A Preferred. This warrant vested at issuance&#13;in June 2017. The Company used the BSM to value the warrant and the fair value at the date of issuance was $479. The number of&#13;common shares issuable upon the exercise of this warrant was not fixed as it could vary by a factor of 1.000 to 1.333 common shares&#13;per warrant share in accordance with the IPO price, and the Company considered the warrant to be a derivative instrument.

As of December 31, 2017, the&#13;fair value of the warrant was $520 and the $41 increase in value during 2017 was recorded as a component of other income and expense.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;As of September 30, 2018,&#13;the fair value of the warrants was $1,577 and the $1,057 increase in value during 2018 was recorded as a component of other income&#13;and expense. The fair value assumptions included an expected term of five years, expected volatility of 85%, a risk-free interest&#13;rate of 2.9% and estimate of the conversion rate. These warrants are classified as warrant liability on the Company&amp;#8217;s balance&#13;sheets. In accordance with the Company&amp;#8217;s IPO in November 2018, the number of shares issuable upon the exercise of these warrants&#13;became fixed which eliminates the fair value adjustment after that date.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The weighted average exercise&#13;price of the outstanding warrants for the consultant and placement agent as of both December 31, 2017 and September 30, 2018 was&#13;$1.56 per share.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The holders of these&#13;warrants or their permitted transferees, are entitled to rights with respect to the registration under the Securities Act of their&#13;shares that are converted to common stock, including demand registration rights and piggyback registration rights.

The guidance under ASC 718 requires companies&#13;to estimate the fair value of the stock-based compensation awards on the date of grant for employees and directors and record expense&#13;over the related service periods, which are generally the vesting period of the equity awards. Awards for consultants are accounted&#13;for under ASC 505-50 &amp;#8212; Equity Based Payments to Non-Employees. Compensation expense is recognized over the period during&#13;which services are rendered by such consultants and non-employees until completed. At the end of each financial reporting period&#13;prior to completion of the service, the fair value of these awards is remeasured using the then-current fair value of the Company&amp;#8217;s&#13;common stock and updated assumption inputs in the Black-Scholes-Merton option-pricing model (&amp;#8220;BSM&amp;#8221;).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;The Company estimates&#13;the fair value of stock-based option awards to its employees and directors using the BSM. The BSM requires the input of subjective&#13;assumptions, including the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of&#13;the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined from the implied&#13;yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options or warrants.&#13;Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options&#13;granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies&amp;#8217;&#13;historical volatility, which management believes represents the most accurate basis for estimating expected future volatility&#13;under the current conditions. The Company accounts for forfeitures as they occur.&lt;/p&gt;</us-gaap:ShareBasedCompensationOptionAndIncentivePlansPolicy>

Fair value represents the price that would be received to sell an asset or paid to transfer&#13;a liability in an orderly transaction between market participants at the measurement date. Fair value accounting requires characterization&#13;of the inputs used to measure fair value into a three-level fair value hierarchy as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&lt;b&gt;&lt;i&gt;Level 1&lt;/i&gt;&lt;/b&gt;&#13;&amp;#8212; Inputs based on quoted prices in active markets for identical assets or liabilities.

The determination of the fair values stated below takes&#13;into account the market for the Company&amp;#8217;s financials, assets and liabilities, the associated credit risk and other factors&#13;as required.

The Company is currently evaluating ASU 2018-07 to determine the effect on the Company&amp;#8217;s&#13;financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in"&gt;In August 2018, the SEC&#13;adopted the final rule under SEC Release No. 33-10532, &lt;i&gt;Disclosure Update and Simplification&lt;/i&gt;, amending certain disclosure&#13;requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure&#13;requirements on the analysis of stockholders&amp;#8217; equity for interim financial statements. Under the amendments, an analysis&#13;of changes in each caption of stockholders&amp;#8217; equity presented in the balance sheet must be provided in a note or separate&#13;statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which&#13;a statement of operations is required to be filed. This final rule became effective on November 5, 2018. On September 25, 2018,&#13;the SEC released guidance advising that it will not object to a registrant adopting the requirement to include changes in stockholders&amp;#8217;&#13;equity in the Form 10-Q for the first quarter beginning after the effective date of the rule. The Company does not expect the&#13;adoption of SEC Release No. 33-10532 to have a material impact on its financial position, results of operations and related disclosures.&#13;The Company anticipates adopting SEC Release No. 33-10532 in its Form 10-Q filing for the quarter ending March 31, 2019.&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Eton Pharmaceuticals,
Inc. (&#8220;Eton&#8221; or the &#8220;Company&#8221;) was incorporated as a Delaware &#8220;C&#8221; corporation on April 27,
2017 and was initially set up as a wholly-owned subsidiary of Imprimis Pharmaceuticals, Inc. (&#8220;Imprimis&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Eton raised $20,055 in
start-up capital through the sale of its Series A redeemable convertible preferred stock (&#8220;Series A Preferred&#8221;) in
June 2017 and a separate management team was then established for Eton with its corporate offices located in Deer Park, Illinois.
Eton is a specialty pharmaceutical company focused on developing and commercializing prescription drug products utilizing the U.S.
Food and Drug Administration&#8217;s (the &#8220;FDA&#8221;) 505(b)(2) regulatory pathway. The Company&#8217;s business model is
to develop proprietary innovative product candidates that offer commercial and/or functional advantages to currently available
alternatives.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">In November 2018, the
Company completed an initial public offering (&#8220;IPO&#8221;), selling 4,140,000 shares of common stock at an offering price
of $6.00 per share, including pursuant to the underwriter&#8217;s exercise in full of its option to purchase additional shares.
The Company received net proceeds of $22,603, after deducting underwriting discounts and commissions and offering-related expenses
(see Note 12).&#160;</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">As of December 31, 2017
and September 30, 2018, the Company had an accumulated deficit of $8,639 and $19,806, respectively. In addition, for the period
from April 27, 2017 (inception) to December 31, 2017 and for the nine months ended September 30, 2018, the Company had net cash
used in operating activities of $4,718 and $6,371, respectively.</p>

Company has not generated any revenues and does not anticipate generating any revenues unless and until it successfully completes
development and obtains regulatory approval for one of its product candidates. </font>As of September 30, 2018, the Company had
an accumulated deficit of $19,806 and has incurred negative cash flow from operating activities since its inception. The Company
currently believes its existing cash and cash equivalents, together with the net cash proceeds received from the closing of its
IPO on November 15, 2018 of $22,603 (see Note 12), will be sufficient to fund its operating expenses and capital expenditure requirements
for at least the next 24 months from the date of issuance of these financial statements. This estimate is based on the Company&#8217;s
current assumptions, including assumptions relating to its ability to manage its spending. The Company could use its available
capital resources sooner than currently expected. Accordingly, t<font style="background-color: white">he Company could seek to
obtain additional capital through equity financings, the sale of debt or other arrangements. However, there can be no assurance
that the Company will be able to raise additional capital if needed or under acceptable terms, if at all. The sale of additional
equity may dilute existing stockholders and newly issued shares may contain senior rights and preferences compared to currently
outstanding common shares. Issued debt securities may contain covenants and limit the Company&#8217;s ability to pay dividends
or make other distributions to stockholders. If the Company is delayed in completing its product development and obtaining regulatory
approval for its product candidates and is unable to obtain such additional financing, operations would need to be scaled back
or discontinued.</font></p><span></span>

balance sheet as of September 30, 2018, the condensed statements of operations and cash flows for the periods ended September 30,
2018 and 2017, and the statement of redeemable convertible preferred stock and stockholders&#8217; deficit for the nine months
ended September 30, 2018 are unaudited. The unaudited interim financial statements have been prepared on the same basis as the
audited financial statements and, in the opinion of management, reflect all adjustments necessary for the fair presentation of
the Company&#8217;s financial position as of September 30, 2018 and the results of its operations and its cash flows for the periods
ended September 30, 2018 and 2017. The financial data and other information disclosed in these notes related to the periods ended
September 30, 2018 and 2017 are also unaudited. The results for the periods ended September 30, 2018 are not necessarily indicative
of results to be expected for the year ending December 31, 2018, any other interim periods or any future year or period.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The preparation of financial
statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets
and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed financial statements and the
reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these
condensed financial statements include, but are not limited to, the accrual of research and development expenses and the valuation
of common stock, stock options, warrants and derivative instruments. Estimates are periodically reviewed in light of changes in
circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results
could differ from those estimates or assumptions.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company operates the
business on the basis of a single reportable segment, which is the business of developing and commercializing prescription drug
products. The Company&#8217;s chief operating decision-maker is the Chief Executive Officer (&#8220;CEO&#8221;), who evaluates
the Company as a single operating segment.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company considers
all highly liquid investments with an original maturity of three months or less to be cash equivalents. All cash and cash equivalents
are held in U.S. financial institutions. Cash equivalents consist of an interest-bearing checking account. From time to time, amounts
deposited exceed federally insured limits. The Company believes the associated credit risk to be minimal.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company capitalizes
certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings
as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded
in stockholders&#8217; deficit as a reduction of proceeds generated as a result of the offering. Should the planned equity financing
be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the statements of operations.
The Company recorded deferred offering costs of $0 and $397 as of December 31, 2017 and September 30, 2018, respectively, which
is included in other long-term assets on the accompanying condensed balance sheet.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company has classified
the Series A Preferred outside of stockholders&#8217; equity (deficit) because the shares contain certain redemption features that
are not solely within the control of the Company. The carrying value of the Series A Preferred is accreted to its redemption value
from the date of issuance through the earliest date of redemption.</p>

(&#8220;R&#38;D&#8221;) expenses include both internal R&#38;D activities and external contracted services. Internal R&#38;D activity
expenses include salaries, benefits and stock-based compensation and other costs to support the Company&#8217;s R&#38;D operations.
External contracted services include product development efforts including certain product licensor milestone payments, clinical
trial activities, manufacturing and control-related activities and regulatory costs. R&#38;D expenses are charged to operations
as incurred. The Company reviews and accrues R&#38;D expenses based on services performed and relies upon estimates of those costs
applicable to the stage of completion of each project. Significant judgments and estimates are made in determining the accrued
balances at the end of any reporting period. Actual results could differ from the Company&#8217;s estimates.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

payments made for the licensing of technology are expensed as R&#38;D in the period in which they are incurred. Nonrefundable advance
payments for goods or services to be received in the future for use in R&#38;D activities are recorded as prepaid expenses and
are expensed as the related goods are delivered or the services are performed.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Basic net loss per common
share is computed by dividing net loss attributable to common stockholders for the period by the weighted average number of common
shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders
for the period by the weighted average number of common and common equivalent shares, such as Series A Preferred, unvested restricted
stock, stock options and warrants, outstanding during the period. Common stock equivalents are excluded from the computation where
their inclusion would be anti-dilutive. No such adjustments were made for 2017 or 2018 as the Company reported a net loss for the
periods ended September 30, 2017 and 2018 as including the effects of common stock equivalents in the diluted EPS calculation would
have been antidilutive (See Note 9).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company estimates
the fair value of certain warrants at each reporting period using Level 3 inputs. The estimates in valuation models are based,
in part, on subjective assumptions, including but not limited to stock price volatility, the expected life of the warrants, the
risk-free interest rate and the exercise price of the warrants, and could differ materially in the future. Changes in the fair
value of the warrant liability during the period are recorded as a component of other income (expense). The Company will continue
to adjust the fair value of the warrant liability at the end of each reporting period for changes in fair value until the earlier
of the exercise or expiration of the applicable warrants, or when the number of shares issuable upon exercise of these warrants
is fixed which occurred with the Company&#8217;s IPO in November 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company accounts for
stock-based compensation under the provisions of the Financial Accounting Standards Board (the &#8220;FASB&#8221;) Accounting Standards
Codification (&#8220;ASC&#8221;) &#8212; 718 Compensation &#8212; Stock Compensation. The guidance under ASC 718 requires companies
to estimate the fair value of the stock-based compensation awards on the date of grant for employees and directors and record expense
over the related service periods, which are generally the vesting period of the equity awards. Awards for consultants are accounted
for under ASC 505-50 &#8212; Equity Based Payments to Non-Employees. Compensation expense is recognized over the period during
which services are rendered by such consultants and non-employees until completed. At the end of each financial reporting period
prior to completion of the service, the fair value of these awards is remeasured using the then-current fair value of the Company&#8217;s
common stock and updated assumption inputs in the Black-Scholes-Merton option-pricing model (&#8220;BSM&#8221;).</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company estimates
the fair value of stock-based option awards to its employees and directors using the BSM. The BSM requires the input of subjective
assumptions, including the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of
the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined from the implied
yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options or warrants.
Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options
granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies&#8217;
historical volatility, which management believes represents the most accurate basis for estimating expected future volatility under
the current conditions. The Company accounts for forfeitures as they occur.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">We measure certain of
our assets and liabilities at fair value. Fair value represents the price that would be received to sell an asset or paid to transfer
a liability in an orderly transaction between market participants at the measurement date. Fair value accounting requires characterization
of the inputs used to measure fair value into a three-level fair value hierarchy as follows:</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Fair value measurements
are classified based on the lowest level of input that is significant to the measurement. The Company&#8217;s assessment of the
significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the assets
and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values stated below takes
into account the market for the Company&#8217;s financials, assets and liabilities, the associated credit risk and other factors
as required. The Company considers active markets as those in which transactions for the assets or liabilities occur in sufficient
frequency and volume to provide pricing information on an ongoing basis.</p>

Company&#8217;s warrant liability at inception and for subsequent mark-to-market fair value measurements are based on management&#8217;s
valuation model and expectations with respect to the method and timing of settlement. The Company has determined that the warrant
liability fair values are classified as Level 3 measurements within the fair value hierarchy.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">In February 2016, the
FASB issued ASU 2016-02 (Topic 842) &#8211; Leases, which requires the lease rights and obligations arising from lease contracts,
including existing and new arrangements, with terms more than 12 months to be recognized as assets and liabilities on the balance
sheet. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The
amendments also require certain quantitative and qualitative disclosures about leasing arrangements. ASU 2016-02 is effective for
reporting periods beginning after December 15, 2018 with early adoption permitted. While the Company is still evaluating ASU 2016-02,
the Company expects the adoption of ASU 2016-02 will not have a material effect on the Company&#8217;s financial condition from
the recognition of the lease rights and obligations as assets and liabilities. The Company is currently evaluating ASU 2016-02
to determine the effect on the Company&#8217;s results of operations and cash flows.</p>

issued ASU 2018-07, Compensation &#8212; Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting,
which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies
to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor&#8217;s
own operations by issuing share-based payment awards. ASU 2018-07 will be effective for financial statements issued for fiscal
years beginning after December 15, 2018, and interim periods within those fiscal years with early adoption permitted (but no sooner
than the adoption of Topic 606). The Company is currently evaluating ASU 2018-07 to determine the effect on the Company&#8217;s
financial statements.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">In August 2018, the SEC
adopted the final rule under SEC Release No. 33-10532, <i>Disclosure Update and Simplification</i>, amending certain disclosure
requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure
requirements on the analysis of stockholders&#8217; equity for interim financial statements. Under the amendments, an analysis
of changes in each caption of stockholders&#8217; equity presented in the balance sheet must be provided in a note or separate
statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which
a statement of operations is required to be filed. This final rule became effective on November 5, 2018. On September 25, 2018,
the SEC released guidance advising that it will not object to a registrant adopting the requirement to include changes in stockholders&#8217;
equity in the Form 10-Q for the first quarter beginning after the effective date of the rule. The Company does not expect the
adoption of SEC Release No. 33-10532 to have a material impact on its financial position, results of operations and related disclosures.
The Company anticipates adopting SEC Release No. 33-10532 in its Form 10-Q filing for the quarter ending March 31, 2019.</p><span></span>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The warrant liability
in the table above is composed of the fair value of a warrant to purchase shares of common stock that were issued to the Company&#8217;s
placement agent in connection with the Series A Preferred offering (see Note 5). The fair value of the warrant liability was determined
based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy.
The Company used the BSM, which incorporates assumptions and estimates, to value the warrant. Estimates and assumptions impacting
the fair value measurement include the fair value per share of the underlying shares of common stock, the remaining contractual
term of the warrant, risk-free interest rate, expected dividend yield and expected volatility of the price of the underlying common
stock. The Company determined the fair value per share of the underlying common stock by taking into consideration the most recent
sales of its preferred stock, results obtained from third-party valuations and additional factors that are deemed relevant. The
Company historically has been a private company and lacks company-specific historical and implied volatility information of its
common stock. Therefore, the Company estimates its expected stock volatility based on the historical volatility of publicly traded
peer companies for a term equal to the remaining contractual term of the warrant. The risk-free interest rate is determined by
reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining contractual term of the warrant.
The Company estimated a 0% expected dividend yield based on the fact that the Company has never paid or declared dividends and
does not intend to do so in the foreseeable future.</p>

Preferred Stock &#8212; Series A</u></b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company has 10,000,000
authorized shares of $0.001 par value preferred stock as per its Amended and Restated Certificate of Incorporation. In June 2017,
the Company issued 6,685,082 Series A Preferred at a price of $3.00 per share and all shares remained outstanding as of December
31, 2017 and September 30, 2018. The gross proceeds were $20,055 from the Series A Preferred stock offering. The Series A Preferred
stockholders or their permitted transferees, are entitled to rights with respect to the registration under the Securities Act of
1933, as amended (the &#8220;Securities Act&#8221;), of their shares that are converted to common stock, including demand registration
rights and piggyback registration rights. These rights are provided under the terms of a registration rights agreement between
the Company and the investors.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">As of December 31, 2017,
the liquidation value of the mezzanine Series A Preferred was $20,698, which consisted of the issuance amount of $20,055 plus accrued
dividends of $643. As of September 30, 2018, the liquidation value of the mezzanine Series A Preferred was $21,598, which consisted
of the issuance amount of $20,055 plus accrued dividends of $1,543.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Series A Preferred
automatically converted to common shares upon completion of the IPO in November 2018. The conversion share calculation was based
on the $3.00 initial issue price for the Series A Preferred plus any accrued but unpaid dividends and automatically converted into
shares of the Company&#8217;s common stock using a stated divisor conversion price equal to 50% of the IPO price to the public
which was $6.00 per share. In accordance with relevant accounting literature, since the terms of the conversion option did not
permit the Company to compute the additional number of shares that it would need to issue upon conversion of the Series A Preferred
when the contingent event occurred, the Company recorded the beneficial conversion amount as a deemed dividend at the date of the
IPO in November 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">As a result of the Series
A Preferred having a possible cash redemption feature in the event that an IPO or alternate financing was not available by December
31, 2018, the Series A Preferred is classified as temporary equity and not included as part of Company&#8217;s stockholders&#8217;
deficit. In accordance with that classification, the $2,534 of issuance costs associated with the Series A Preferred offering are
being ratably accreted as a deemed dividend using the effective interest method over its expected term.</p>

years from the date of issuance. The Company used the BSM to value the warrant and the fair value at the date of issuance was $121
based on an expected term of five years, volatility of 85%, a risk-free interest rate of 1.8% and a 0% rate on expected dividends.
The $121 amount for the consulting warrants was expensed as a component of the Company&#8217;s general and administrative expenses
in May 2017.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">In conjunction with the
closing of the Series A Preferred offering in June 2017 (See Note 5), the Company issued a warrant to purchase 649,409 shares of
its common stock to the placement agent at an exercise price of $3.00 per share, provided, however, upon the conversion of the
Series A Preferred, the warrant shall adjust to entitle the holder to purchase shares of common stock equal to 10.0% of the shares
of common stock issuable upon conversion of the Series A Preferred (excluding 191,000 shares of Series A Preferred that were purchased
by insiders) and the exercise price shall adjust to the conversion price of the Series A Preferred. This warrant vested at issuance
in June 2017. The Company used the BSM to value the warrant and the fair value at the date of issuance was $479. The number of
common shares issuable upon the exercise of this warrant was not fixed as it could vary by a factor of 1.000 to 1.333 common shares
per warrant share in accordance with the IPO price, and the Company considered the warrant to be a derivative instrument. The $479
amount was recorded as a component of the issuance costs for the Series A Preferred in June 2017. As of December 31, 2017, the
fair value of the warrant was $520 and the $41 increase in value during 2017 was recorded as a component of other income and expense.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">As of September 30, 2018,
the fair value of the warrants was $1,577 and the $1,057 increase in value during 2018 was recorded as a component of other income
and expense. The fair value assumptions included an expected term of five years, expected volatility of 85%, a risk-free interest
rate of 2.9% and estimate of the conversion rate. These warrants are classified as warrant liability on the Company&#8217;s balance
sheets. In accordance with the Company&#8217;s IPO in November 2018, the number of shares issuable upon the exercise of these warrants
became fixed which eliminates the fair value adjustment after that date.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The weighted average exercise
price of the outstanding warrants for the consultant and placement agent as of both December 31, 2017 and September 30, 2018 was
$1.56 per share.</p>

warrants or their permitted transferees, are entitled to rights with respect to the registration under the Securities Act of their
shares that are converted to common stock, including demand registration rights and piggyback registration rights. These rights

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">The Company&#8217;s board
of directors and stockholders approved the Eton Pharmaceuticals, Inc. 2017 Equity Incentive Plan in May 2017 (the &#8220;Plan&#8221;),
which authorizes the issuance of up to 5,000,000 shares of the Company&#8217;s common stock. The Company has granted RSAs, stock
options and restricted stock units (&#8220;RSUs&#8221;) for its common stock under the Plan as detailed in the tables below. There
were 976,020 shares available for future issuance under the Plan as of September 30, 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Shares that are expired,
terminated, surrendered or canceled without having been fully exercised will be available for future awards under the Plan. The
exercise price for stock options granted is not less than the fair value of common shares as determined by the board of directors
as of the date of grant. The Company&#8217;s board of directors values the Company&#8217;s common stock, taking into consideration
its most recently available valuation of common stock performed by third parties as well as additional factors which may have changed
since the date of the most recent contemporaneous valuation through the date of grant.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">On January 1, 2018, the
Company issued 54,745 restricted shares of its common stock to each of its four outside directors (218,980 total shares). The restricted
shares issued to the outside directors vest 25% at each quarter-end in 2018 and will be 100% vested at December 31, 2018.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">To date, all stock options
issued have been non-qualified stock options and the exercise prices were set at the fair value for the shares at the dates of
grant. Options typically have a ten-year life except for options to purchase 50,000 shares of the Company&#8217;s common stock
granted to product consultants that expire within five years if the Company is not able to file certain product submissions to
the FDA prior to the five-year expiration date. Furthermore, these option awards to the Company&#8217;s product consultants do
not vest unless certain product submissions are made to the FDA, and accordingly, the Company has not recorded any expense for
these contingently vesting option awards to its product consultants.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Expected Term &#8212;
The Company has opted to use the &#8220;simplified method&#8221; for estimating the expected term of options granted to employees
and directors, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of
the option (generally 10 years). The expected term of options granted to non-employees equals the contractual life of the options.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Expected Volatility &#8212;
Due to the Company&#8217;s limited operating history and a lack of Company-specific historical and implied volatility data, the
Company has based its estimate of expected volatility on the historical volatility of a group of similar companies that are publicly
traded. The historical volatility data was computed using the daily closing prices for the selected companies&#8217; shares during
the equivalent period of the calculated expected term of the stock-based awards.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Risk-Free Interest Rate
&#8212; The risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of
the Company&#8217;s stock options.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Expected Dividend &#8212;
The Company has not issued any dividends in its history and does not expect to issue dividends over the life of the options and
therefore has estimated the dividend yield to be zero.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.25in">Fair value of Common Stock
&#8212; Prior to the Company&#8217;s IPO in November 2018, the fair value of the shares of common stock underlying the stock-based
awards was determined by the board of directors, with input from management. Because there was no public market for the Company&#8217;s
common stock, the board of directors determined the fair value of the common stock on the grant-date of the stock-based award by
considering a number of objective and subjective factors, including enterprise valuations of the Company&#8217;s common stock performed
by an unrelated third-party specialist, valuations of comparable companies, sales of the Company&#8217;s convertible preferred
stock to unrelated third parties, operating and financial performance, the lack of liquidity of the Company&#8217;s capital stock,
and general and industry-specific economic outlook. The board of directors intended all options granted to be exercisable at a
price per share not less than the estimated per share fair value of common stock underlying those options on the date of grant.</p>

shares of the Company&#8217;s common stock at the formation of the Company at the $0.001 par value per share price as the paid-in-capital
contribution from Imprimis. The Company and Imprimis signed licensing agreements for two products developed by Imprimis whereby
Imprimis assigned the product rights to the Company. The Company will pay Imprimis a $50 milestone payment upon patent approval
for each product and a royalty fee at a rate of six percent on the net sales of those two products. On December 26, 2017, one of
the products had its patent approved and a $50 milestone fee was recognized as R&#38;D expense by the Company in 2017 and paid
to Imprimis in January 2018. In July 2018, the Company determined the patent-approved product was not viable for its portfolio
of product opportunities and Imprimis paid the Company $50 to cancel the licensing agreement for the one product and retain the
product rights at Imprimis.</p>

for the Company&#8217;s pharmaceutical business, key executives at Imprimis received 1,500,000 shares of restricted common stock
in the Company for consulting services and certain Imprimis managers also received options to purchase 130,000 shares of common
stock from the Company (20,000 of these options were forfeited in 2018). The restricted stock and stock options vested 100% after
one year on April 30, 2018. The Company recorded stock-based compensation expense of $970 and $856 for the Imprimis restricted
common stock and $51 and $70 for Imprimis stock options, respectively, for the periods ended September 30, 2018 and 2017 as a component
of its general and administrative expenses.</p>

The Company also holds a right of first refusal to obtain the exclusive license rights for geographic areas outside of the United
States. Pursuant to the Eyemax Agreement, the Company is responsible for all costs of testing and FDA approval of the product,
other than the FDA filing fee which will be paid by Eyemax. The Company is also responsible for commercializing the product in
the United States at its expense. The Company paid Eyemax $250 upon execution of the Eyemax Agreement, which was recorded as a
component of research and development expense and will pay Eyemax $250 upon FDA approval and $500 upon the first commercial sale
of the product. The Company will also pay Eyemax a royalty of 10% on the net sales of all products. The Eyemax Agreement is for
an initial term of 10 years from the date of the Eyemax Agreement, subject to successive two-year renewals unless the Company elects
to terminate the Eyemax Agreement. There were no amounts due under the terms of the Eyemax Agreement as of December 31, 2017 and

CEO (&#8220;Andersen&#8221;). The Company also holds an option to purchase the DS-100 product and all related intellectual property
and government approvals at a price of one dollar. Pursuant to the Andersen Agreement, Andersen is responsible for obtaining FDA
approval at its expense and manufacturing the product for sale to the Company at its cost. The Company is responsible for commercializing
the product in the United States at its expense. The Company paid Andersen $750 upon execution of the Andersen Agreement, which
was recorded as a component of research and development expense and will pay Andersen $750 upon successful completion of three
registration batches of product, $750 upon submission of an NDA and $750 upon FDA approval. The Company will also pay Andersen
50% of the net profit from the sale of the product. The Andersen Agreement is for an initial term of five years from the first
commercial sale of the product, subject to successive two-year renewals unless either party elects to terminate the Andersen Agreement.
There were no amounts due under the terms of the Andersen Agreement as of December 31, 2017 or September 30, 2018. The aforementioned
option to purchase the product and all related intellectual property and government approvals was considered to represent variable
interest in the affiliated entity. The affiliated entity was not considered to be a variable interest entity.</p>

External contracted services include product development efforts including certain product licensor milestone payments, clinical
trial activities, manufacturing and control-related activities and regulatory costs. R&#38;D expenses are charged to operations
as incurred. The Company reviews and accrues R&#38;D expenses based on services performed and relies upon estimates of those costs
applicable to the stage of completion of each project. Significant judgments and estimates are made in determining the accrued
balances at the end of any reporting period. Actual results could differ from the Company&#8217;s estimates.</p>

over the related service periods, which are generally the vesting period of the equity awards. Awards for consultants are accounted
for under ASC 505-50 &#8212; Equity Based Payments to Non-Employees. Compensation expense is recognized over the period during

the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined from the implied
yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options or warrants.
Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options
granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies&#8217;
historical volatility, which management believes represents the most accurate basis for estimating expected future volatility
under the current conditions. The Company accounts for forfeitures as they occur.</p><span></span>

requirements on the analysis of stockholders&#8217; equity for interim financial statements. Under the amendments, an analysis
of changes in each caption of stockholders&#8217; equity presented in the balance sheet must be provided in a note or separate
statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which
a statement of operations is required to be filed. This final rule became effective on November 5, 2018. On September 25, 2018,
the SEC released guidance advising that it will not object to a registrant adopting the requirement to include changes in stockholders&#8217;

Includes any type of security that is redeemable at a fixed or determinable price or on a fixed or determinable date or dates, is redeemable at the option of the holder, or has conditions for redemption which are not solely within the control of the issuer. If convertible, the issuer does not control the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the conversion option if the holder exercises the option to convert the stock to another class of equity. If the security is a warrant or a rights issue, the warrant or rights issue is considered to be temporary equity if the issuer cannot demonstrate that it would be able to deliver upon the exercise of the option by the holder in all cases. Includes stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer.</p></div>
