1.
Operations and Organization
 
Operations
Rexahn Pharmaceuticals, Inc. (the “Company”), a Delaware corporation, is a biopharmaceutical company whose principal operations are the development of innovative treatments for cancer.  The Company had an accumulated deficit of $163,909,446 at March 31, 2020 and anticipates incurring losses in the foreseeable future.  In September 2019, the Company commenced a process to explore and evaluate strategic alternatives to enhance shareholder value and engaged a financial advisory firm to assist in the process.

The Company believes that its cash and cash equivalents of approximately $11.0 million as of March 31, 2020 will be sufficient to cover its cash flow requirements for its current activities for at least the next 12 months from the date these financial statements were issued.

Basis of Presentation
The accompanying unaudited condensed financial statements of the Company have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial information.  Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements.  In the opinion of the Company’s management, all adjustments (consisting of only normal recurring accruals) considered necessary for a fair presentation of the Company’s financial position as of March 31, 2020 and December 31, 2019 and of the results of operations, comprehensive loss, stockholders’ equity and cash flows for the three months ended March 31, 2020 and 2019 have been included.  Operating results for the three months ended March 31, 2020 are not necessarily indicative of results that may be expected for any other interim period or the full fiscal year ending December 31, 2020. The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (the “2019 Form 10-K”).  Information included in the condensed balance sheet as of December 31, 2019 has been derived from the Company’s audited financial statements for the year ended December 31, 2019 included in the 2019 Form 10-K.  The unaudited condensed financial statements have been prepared on a basis that assumes the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future.  Actual results may ultimately differ from these estimates.  These estimates are reviewed periodically, and as adjustments become necessary, they are reported in earnings in the period in which they become available.

COVID-19 Pandemic
The outbreak of the COVID-19 disease, which the World Health Organization declared a pandemic in March 2020, has led to disruption in the global economy and the biopharmaceutical industry. The extent of the COVID-19 pandemic’s impact on the Company’s business, financial condition and results of operations, as well as the Company’s ability to enter into and complete a strategic transaction, is highly uncertain and will depend on various factors, including the duration and scope of the pandemic, restrictions on business and social distancing guidelines that may be requested or mandated by governmental authorities, other actions taken to contain the impact of the pandemic, and impacts on the Company’s ability or the ability of potential strategic partners to access the markets on favorable terms, or at all.

2.
Marketable Securities

Marketable securities are considered “available-for-sale” in accordance with Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 320, “Debt and Equity Securities,” and thus are reported at fair value in the Company’s accompanying balance sheet, with unrealized gains and losses excluded from earnings and reported as a separate component of stockholders’ equity.  Amounts reclassified out of accumulated other comprehensive income (loss) into realized gains and losses are accounted for on the basis of specific identification and are included in other income or expense in the statement of operations.  The Company classifies such investments as current on the balance sheet as the investments are readily marketable and available for use in current operations.

The Company had no marketable securities as of March 31, 2020.  The following table shows the Company’s marketable securities’ adjusted cost, gross unrealized gains and losses, and fair value by significant investment category as of December 31, 2019:

License Agreements

BioSense Global LLC
 
On March 10, 2020, the Company entered into an amendment to its collaboration and license agreement, (as amended, the “License and Assignment Agreement”) with BioSense Global LLC (“BioSense”) to advance the development and commercialization of RX-3117 for all human uses in the Republic of Singapore, China, Hong Kong, Macau, and Taiwan (the “Territory”). Under the terms of the License and Assignment Agreement, upon payment in full of an upfront payment, the Company will (i) grant BioSense an exclusive license to develop and commercialize pharmaceutical products containing RX-3117 as a single agent for all human uses in the Territory and (ii) assign and transfer all of the Company’s patents and patent applications related to RX-3117 in the Territory. The upfront payment consists of an aggregate of $1,650,000, of which $1,500,000 has been received to date. Under the License and Assignment Agreement, the Company is eligible to receive milestone payments in an aggregate of up to $84.5 million upon the achievement of development, regulatory and commercial goals and will also be eligible to receive tiered royalties in the mid-single digits to low tens on annual net sales in the Territory.
 
The Company has evaluated the License and Assignment Agreement under ASC 606, “Revenue from Contracts with Customers,” to determine the appropriate amount of revenue to be recognized as the Company fulfills its obligations under the License and Assignment Agreement.  The Company identified the exclusive license to develop RX-3117 and the supply of RX-3117 drug product, drug substance and intermediate materials (collectively, the “Transferred Materials”) as the distinct performance obligations in the contract.  The Company has determined that it will recognize revenue related to the exclusive license to develop RX-3117 and the supply of the Transferred Materials transfers to BioSense at a point in time when the exclusive license is conveyed and the Transferred Materials are made available for delivery to BioSense, respectively.
 
The Company has determined the transaction price contains both fixed and variable consideration.  The fixed consideration is equal to the upfront payment of $1,650,000.  The variable consideration relates to the milestone payments and future sales-based royalty payments.  The Company estimates the variable consideration in the contract using the most likely amount method.  The Company determined at the contract outset and as of March 31, 2020 that all milestone payments should be fully constrained, as it is not probable that a significant reversal of revenue will not occur in a future period, given the significance of the milestone payments and that the payments are earned based upon the achievement of events that are highly susceptible to factors outside of the Company’s control.  Future sales-based royalties related to the exclusive license to develop RX-3117 will be recognized in the period the underlying sales transaction occurs.
 
The $1,650,000 upfront payment has been allocated to the performance obligations on the basis of the relative standalone selling price estimated for each performance obligation. The Company has determined the standalone selling price of the exclusive license to develop RX-3117 using the adjusted market approach, which represents the price the market will bear based on the license rights granted and the state of the intellectual property, and has determined the standalone selling price of the supply of the Transferred Materials using a cost approach.  Accordingly, the Company has allocated $750,000 of the upfront transaction price to the exclusive license to develop RX-3117 and $900,000 to the supply of the Transferred Materials.  Additional transaction price recognized in future periods related to milestone payments and royalties will be allocated solely to the exclusive license to develop RX-3117, as these amounts relate to efforts associated with the development and commercialization of products related to the exclusive license to develop RX-3117.

As of March 31, 2020, $1,500,000 of the upfront payment had been paid, and the remaining $150,000 remained unpaid.  As of March 31, 2020, the Company had satisfied the performance obligation related to the Transferred Materials and therefore recognized $900,000 in revenue which was previously classified as deferred revenue.  As of March 31, 2020, the exclusive license had not been transferred and no revenue was recognized related to that performance obligation.  Therefore, the Company has recorded the additional $600,000 of transaction consideration received as of March 31, 2020 as deferred revenue on the Company’s balance sheet.
 
Zhejiang HaiChang Biotechnology Co., Ltd.
 
On February 8, 2020, the Company entered into an exclusive license agreement (the “HaiChang License Agreement”) with Zhejiang HaiChang Biotechnology Co., Ltd. (“HaiChang”) pursuant to which the Company granted HaiChang an exclusive (even as to the Company), royalty-bearing, sublicensable worldwide license to research, develop and commercialize pharmaceutical products comprising RX-0201 (subject to and limited by the exclusive rights of NEXT BT Co. Ltd (“Next BT”) with respect to RX-0201 in Asia), the nano-liposomal formulation of RX-0201 known as RX-0301, and RX-0047, a proprietary compound currently in preclinical development. HaiChang has agreed to use commercially reasonable efforts to develop, seek regulatory approval for, and commercialize one product comprising RX-0301 and one product comprising RX-0047.

HaiChang paid a one-time upfront payment of $250,000 to the Company for certain materials to be transferred by the Company to HaiChang.  HaiChang will pay the Company development milestone payments in an aggregate of up to $63,000,000 with respect to RX-0201 and RX-0301 and up to $33,000,000 with respect to RX-0047, and royalties based on percentages of net sales in the low tens with respect to RX-0201 and RX-0301 and the mid-single digits with respect to RX-0047.  However, if HaiChang exclusively sublicenses its rights to a third party with respect to RX-0201 and RX-0301 or RX-0047 in a particular jurisdiction, instead of the foregoing milestones and royalties to the extent relating to such compound(s) and jurisdiction, HaiChang will pay the Company a percentage of any sublicensing revenue received by HaiChang, provided that in any event HaiChang will pay a milestone payment on initiation of a Phase 3 clinical trial that is subject to reduction by the amount of any sublicensing revenue paid with respect to the applicable compound(s) as of the time of initiation of the trial.

The Company accounts for the HaiChang License Agreement under ASC 606.  The Company has determined the performance obligations under the contract relate to the transfer of materials and the license of intellectual property.  Revenue associated with the materials and license are recognized at a point in time.  The Company has determined the transaction price contains both fixed and variable consideration.  The fixed consideration is equal to the upfront payment of $250,000.  At the outset of the contract, the value of the license was determined to be de minimis given the early stage of clinical development of the intellectual property, and allocated the entire fixed consideration to the materials.  The Company transferred the materials during the three months ended March 31, 2020 and therefore recognized the entire fixed consideration as revenue.  The variable consideration relates to the milestone payments, sublicense fees and future sales-based royalty payments.  The Company estimates variable consideration under the contract using the expected value method.  Given the early stage and the uncertain success of the development work to be performed by HaiChang, the Company has determined that the variable consideration in the contract should be fully constrained at the contract outset and as of March 31, 2020.

Leases

The Company leases 5,466 square feet of office space in Rockville, Maryland, with a lease term ending June 30, 2024.  Under the lease agreement, the Company pays its allocable portion of real estate taxes and common area operating charges, which are recorded as variable lease costs.  The lease has escalating rent payments for which the Company records lease expense on a straight-line basis over the lease term, and an option to terminate the leased premises, without penalty, on June 30, 2021.  The Company is reasonably certain that it will not remain in these leased premises after the optional termination date, and therefore, is using the optional termination date in assessing the lease term.

The following table summarizes the right of use lease assets and lease liabilities as of March 31, 2020:

Net Loss per Common Share
 
Basic loss per common share is computed by dividing net loss by the weighted average number of shares of common stock outstanding for the period.  Diluted loss per common share is computed by dividing net loss by the weighted average number of shares of common stock outstanding, plus the number of common share equivalents that would be dilutive.  As of March 31, 2020 and December 31, 2019, there were stock options, and warrants to acquire, in the aggregate, 2,070,511 and 2,126,063 shares of the Company’s common stock, respectively, that are potentially dilutive. However, diluted loss per share is the same as basic loss per share for all periods presented because the inclusion of common share equivalents would be anti-dilutive.

Stock-Based Compensation
 
As of March 31, 2020, the Company had 149,022 options to purchase common stock outstanding.
 
In June 2013, the Company’s shareholders voted to approve the Rexahn Pharmaceuticals, Inc. 2013 Stock Option Plan (the “2013 Plan”).  Under the 2013 Plan, the Company grants equity awards to key employees, directors and consultants of the Company.  The Company has reserved 283,333 shares of common stock for issuance pursuant to the 2013 Plan. As of March 31, 2020, there were 144,366 options outstanding under the 2013 Plan, and 136,936 shares were available for issuance.  In addition, as of March 31, 2020, there were 4,656 options outstanding under a previously established stock option plan under which no new stock options may be granted.
 
Accounting for Awards
 
Stock-based compensation expense is the estimated fair value of options granted amortized on a straight-line basis over the requisite vesting service period for the entire portion of the award. Total stock-based compensation recognized by the Company for the three months ended March 31, 2020 and 2019 is as follows:

Income Taxes
 
No provision for federal and state income taxes was required for the three months ended March 31, 2020 and 2019 due to the Company’s operating losses and increased deferred tax asset valuation allowance.  At March 31, 2020 and December 31, 2019, the Company had unused net operating loss carry-forwards of approximately $157,964,000 and $156,586,000 respectively, which portions of expire at various dates beginning in 2021.  Some of this amount may be subject to annual limitations under certain provisions of the Internal Revenue Code related to “changes in ownership.”
 
As of March 31, 2020 and December 31, 2019, the deferred tax assets related to the aforementioned carry-forwards have been fully offset by valuation allowances, because significant utilization of such amounts is not presently expected in the foreseeable future.

Commitments and Contingencies
 
 
a)
The Company has contracted with various vendors for services, with terms that require payments over the terms of the agreements, usually ranging from two to 36 months. The costs to be incurred are estimated and are subject to revision. As of March 31, 2020, the total estimated cost to complete these agreements was approximately $800,000.  All of these agreements may be terminated by either party upon appropriate notice as stipulated in the respective agreements.
 

b)
On June 22, 2009, the Company entered into a License Agreement with Korea Research Institute of Chemical Technology (“KRICT”) to acquire the rights to all intellectual property related to quinoxaline-piperazine derivatives that were synthesized under a Joint Research Agreement.  The agreement with KRICT calls for a one-time milestone payment of $1,000,000 within 30 days after the first achievement of marketing approval of the first commercial product arising out of or in connection with the use of KRICT’s intellectual property.  As of March 31, 2020, the milestone has not occurred.
 

c)
The Company has established a 401(k) plan for its employees.  The Company has elected to match 100% of the first 3% of an employee’s compensation plus 50% of an additional 2% of the employee’s deferral. Expense related to this matching contribution aggregated to $11,229 and $27,879 for the three months ended March 31, 2020 and 2019, respectively.
 

d)
On February 5, 2018, the Company and Next BT terminated a research collaboration agreement between the Company and Rexgene Biotech Co., Ltd, a predecessor in interest to Next BT.  The Company agreed to pay Next BT a royalty in the low single digits of any net sales of RX-0201 the Company makes in Asia and 50% of the Company’s licensing revenue related to licensing of RX-0201 in Asia, up to an aggregate of $5,000,000.  As of March 31, 2020, the Company has not made any royalty payments to Next BT.

Fair Value Measurements
 
ASC 820 defines fair value as 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, not adjusted for transaction costs.  ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).

The three levels are described below:

Level 1 Inputs
Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company;
     
Level 2 Inputs
Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly;
     
Level 3 Inputs
Unobservable inputs for the asset or liability including significant assumptions of the Company and other market participants.

The following tables present assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

Except for the historical information contained herein, the matters discussed in this Quarterly Report on Form 10-Q may be deemed to be forward-looking statements that involve risks and uncertainties.  We make such forward-looking statements pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and other federal securities laws.  In this Quarterly Report on Form 10-Q, words such as “believe”, “estimate”, “expect”, “anticipate”, “will”, “may”, “intend” and other similar expressions, are intended to identify forward-looking statements.  We caution that forward-looking statements are based largely on our expectations and are subject to a number of known and unknown risks and uncertainties that are subject to change based on factors that are, in many instances, beyond our control.  Actual results, performance or achievements may differ materially from those contemplated, expressed or implied by the forward-looking statements.

Although we believe that the expectations reflected in our forward-looking statements are reasonable as of the date we make them, actual results could differ materially from those currently anticipated due to a number of factors, including risks relating to:


uncertainties about the exploration and evaluation of strategic alternatives, including that they may not result in a definitive transaction or enhance shareholder value and may create a distraction or uncertainty that may adversely affect our operating results, business, or investor perceptions;


uncertainties about the paths of our programs and our ability to evaluate and identify a path forward for those programs, particularly given the constraints we have as a small company with limited financial, personnel and other operating resources;


the impact of the COVID-19 pandemic on the economy, our industry, and our financial condition and results of operations, as well as our ability to enter into and complete a strategic transaction;


our understandings and beliefs regarding the role of certain biological mechanisms and processes in cancer;


our product candidates being in early stages of development, including in preclinical development;


our ability to successfully and timely complete clinical trials for our drug candidates in clinical development;


uncertainties related to the timing, results and analyses related to our drug candidates in preclinical development;


our ability to obtain the necessary U.S. and international regulatory approvals for our drug candidates;



our reliance on third-party contract research organizations and other investigators and collaborators for certain research and development services;


our ability to maintain or engage third-party manufacturers to manufacture, supply, store and distribute supplies of our drug candidates for our clinical trials;
 

our ability to form strategic alliances and partnerships with pharmaceutical companies and other partners for development, sales and marketing of certain of our product candidates;


demand for and market acceptance of our drug candidates;


the scope and validity of our intellectual property protection for our drug candidates and our ability to develop our candidates without infringing the intellectual property rights of others;


our lack of profitability and the need for additional capital to operate our business; and


other risks and uncertainties, including those set forth herein and in the 2019 Form 10-K under the caption “Risk Factors” and those detailed from time to time in our filings with the Securities and Exchange Commission.

These forward-looking statements are made only as of the date hereof, and we undertake no obligation to update or revise the forward-looking statements, whether as a result of new information, future events or otherwise.

We are a clinical stage biopharmaceutical company developing innovative therapies to improve patient outcomes in cancers that are difficult to treat. Our pipeline features two clinical-stage product candidates and additional compounds in preclinical development.
 

RX-3117 is a novel, investigational oral, small molecule nucleoside compound.  Once intracellularly activated (phosphorylated) by the enzyme UCK2, it is incorporated into the DNA or RNA of cells and inhibits both DNA and RNA synthesis, which induces apoptotic cell death of tumor cells.  RX-3117 is the subject of a Phase 2a clinical trial in combination with Celgene’s Abraxane® (paclitaxel protein-bound particles for injectable suspension) as a first-line treatment in patients newly diagnosed with metastatic pancreatic cancer.  The trial reached its target enrollment in February 2019.  As of July 24, 2019, an overall response rate of 23% had been observed in 40 patients that had at least one scan on treatment.  Preliminary and unaudited data indicates that the median progression free survival for patients in the study is approximately 5.4 months.  Complete data from the trial is expected to be available in 2020.  We do not plan to conduct or sponsor any additional trials with RX-3117.

On March 10, 2020, we amended our collaboration and license agreement (as amended, the “License and Assignment Agreement”) with BioSense Global LLC (“BioSense”) to advance the development and commercialization of RX-3117 for all human uses in the Republic of Singapore, China, Hong Kong, Macau, and Taiwan (the “Territory”). Under the terms of the License and Assignment Agreement, upon payment in full of an upfront payment, we will grant BioSense an exclusive license to develop and commercialize pharmaceutical products containing RX-3117 as a single agent for all human uses in the Territory and assign and transfer to BioSense all of our patents and patent applications related to RX-3117 in the Territory. The upfront payment consists of an aggregate of $1,650,000, of which $1,500,000 has been received to date. Under the License and Assignment Agreement, we are eligible to receive milestone payments in an aggregate of up to $84.5 million upon the achievement of development, regulatory and commercial goals and will also be eligible to receive tiered royalties in the mid-single digits to low tens on annual net sales in the Territory.
 

RX-5902 is a potential first-in-class small molecule modulator of the Wnt/beta-catenin pathway which plays a key role in cancer cell proliferation and tumor growth.  In August 2018, we entered into a Clinical Trial Collaboration and Supply Agreement (the “Collaboration Agreement”) with Merck Sharp & Dohme B.V. (“Merck”) to evaluate the combination of RX-5902 and Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) in a Phase 2 trial in patients with metastatic triple negative breast cancer (“TNBC”). On April 7, 2020, we notified Merck that we were terminating the Collaboration Agreement, effective immediately, in connection with our determination to discontinue development of RX-5902 for the treatment of TNBC. We are evaluating development options for RX-5902 and may or may not sponsor additional clinical trials with the compound.


RX-0301 is a potential best-in-class, potent inhibitor of the synthesis of the protein kinase Akt-1, which we believe plays a critical role in cancer cell proliferation, survival, angiogenesis, metastasis, and drug resistance.  RX-0301 is currently in preclinical development by Zhejiang HaiChang Biotechnology Co., Ltd. (“HaiChang”) as a nano-liposomal formulation of RX-0201 (Archexin®) using HaiChang’s proprietary QTsome™ technology On February 8, 2020, we entered into an exclusive license agreement with HaiChang (the “HaiChang License Agreement”) pursuant to which we granted HaiChang an exclusive (even as to us), royalty-bearing, sublicensable worldwide license to research, develop and commercialize RX-0201 and RX-0301. The HaiChang License Agreement supersedes a prior agreement with HaiChang to develop RX-0301 under which HaiChang was to conduct certain preclinical and clinical activities through completion of a Phase 2a proof-of-concept clinical trial in hepatocellular carcinoma.

We have no product sales to date, and our major sources of working capital have been proceeds from various private and public financings and licensing and collaboration agreements with our partners.  In September 2019, we commenced a process to explore and evaluate strategic alternatives to enhance shareholder value, and have engaged Oppenheimer and Co. Inc. as our financial advisor to assist us in this process.  Potential strategic alternatives include an acquisition, merger, reverse merger, other business combination, sales of assets, licensing, or other strategic alternatives.  In connection with the evaluation of strategic alternatives, we are evaluating opportunities to extend our resources and have reduced our headcount to five employees.

The outbreak of the COVID-19 disease, which the World Health Organization declared a pandemic in March 2020, has led to disruption in the global economy and the biopharmaceutical industry. The extent of the COVID-19 pandemic’s impact on our business, financial condition and results of operations, as well as on our ability to enter into and complete a strategic transaction, is highly uncertain and will depend on various factors, including the duration and scope of the pandemic, restrictions on business and social distancing guidelines that may be requested or mandated by governmental authorities, other actions taken to contain the impact of the pandemic, and impacts on our ability or the ability of potential strategic partners to access the markets on favorable terms, or at all.

Results of Operations

Comparison of the Three Months Ended March 31, 2020 and March 31, 2019
 
Total Revenues
 
We recorded revenues of $1,150,000 during the three months ended March 31, 2020, consisting of $250,000 earned from the HaiChang License Agreement and $900,000 from the BioSense License and Assignment Agreement.  We had no revenues for the three months ended March 31, 2019.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related expenses for executive, finance and other administrative personnel, recruitment expenses, professional fees, and other corporate expenses, including business development, investor relations, and general legal activities.

General and administrative expenses decreased approximately $440,000, or 25.9%, to approximately $1,256,000 for the three months ended March 31, 2020 from $1,696,000 for the three months ended March 31, 2019.  The decreases were primarily attributable to decreased personnel and operating costs resulting from the streamlining of operations.

Research and Development Expenses

Research and development costs are expensed as incurred.  These costs consist primarily of salaries and related personnel costs, and amounts paid to contract research organizations, hospitals and laboratories for the provision of services and materials for drug development and clinical trials.  Our research and development expenses are currently related to our oncology drug candidates.

Research and development expenses decreased approximately $1,785,000, or 79.6%, to approximately $457,000 for the three months ended March 31, 2020, from approximately $2,242,000 for the three months ended March 31, 2019.  The decreases are a result of the completion of our RX-3117 and RX-5902 clinical trials, and decreased drug manufacturing costs.

The table below summarizes the approximate amounts incurred in each of our research and development projects for the three months ended March 31, 2020 and 2019:

We expect total research and development expenses to decrease in the remainder of 2020 as compared to the three months ended March 31, 2020 as we complete our Phase 2a clinical trial of RX-3117 with Abraxane and explore and evaluate strategic alternatives.

Interest Income

Interest income decreased approximately $47,000, or 57.7% for the three months ended March 31, 2020, compared to the same period in 2019.  The decreases were primarily attributable to lower interest rates and balances of cash, cash equivalents and marketable securities for the three months ended March 31, 2020 compared to the same period in 2019.

Unrealized (Loss) Gain on Fair Value of Warrants

Our warrants are recorded as liabilities at fair value, and the warrants are valued using a lattice model.  Changes in the fair value of warrants are recorded as an unrealized gain or loss in our statement of operations.  During the three months ended March 31, 2020 and 2019, we recorded unrealized (losses) gains on the fair value of our warrants of approximately $(58,000) and $1,513,000, respectively.  Estimating fair values of warrants requires the development of significant and subjective estimates that may, and are likely to, change over the duration of the warrants due to related changes to external market factors.  The large unrealized gain for the three months ended March 31, 2019 primarily resulted from a significant decrease in the stock price of the underlying common stock at the end of this period compared to the beginnings of this period.

Net Loss

As a result of the above, net loss for the three months ended March 31, 2020 was approximately $587,000 or $0.15 per share, compared to approximately $2,343,000, or $0.62 for the three months ended March 31, 2019.

Liquidity and Capital Resources

Current and Future Financing Needs

We have incurred negative cash flow from operations since we started our business.  We expect to continue to incur negative cash flow and operating losses as we explore strategic alternatives.  We have spent, and subject to our exploration of strategic alternatives, expect to continue to spend, substantial amounts in connection with implementing our business strategy, including our planned product development efforts, our clinical trials and our research and development efforts.  Subject to the result of our exploration of strategic alternatives, we will need to raise additional capital through public or private equity or debt offerings or through arrangements with strategic partners or other sources in order to continue to develop our drug candidates.  In conjunction with our exploration of strategic alternatives, we are exploring opportunities to extend our resources.  We believe that our cash and cash equivalents of approximately $11.0 million as of March 31, 2020 will be sufficient to cover our cash flow requirements for our current activities for at least the next 12 months following the issuance of the financial statements contained in this Quarterly Report. However, our resource requirements could materially change to the extent we identify and enter into any strategic transaction.  Our ability to enter into a strategic transaction could also be impacted by our, or any potential partner’s ability to, raise additional capital.

Cash Flows

Cash used in operating activities was approximately $1,221,000 for the three months ended March 31, 2020.  The operating cash flows during the three months ended March 31, 2020 reflect a net loss of approximately $587,000, a net decrease of cash components of working capital and non-cash charges totaling $634,000. Cash used in operating activities was approximately $4,380,000 for the three months ended March 31, 2019.  The operating cash flows during the three months ended March 31, 2019 reflect a net loss of approximately $2,343,000, an unrealized gain on the fair value of warrants of approximately $1,514,000, and a net increase of cash components of working capital and non-cash charges totaling approximately $523,000.

Cash provided by investing activities was $3,000,000 from the redemption of marketable securities for the three months ended March 31, 2020.  Cash used in investing activities was approximately $5,895,000 for the three months ended March 31, 2019 which consisted of approximately $8,888,000 and approximately $13,000 from the purchases of marketable securities and equipment, respectively, offset by approximately $6,000 from the sale of equipment and $3,000,000 from the redemption of marketable securities.

There was no cash provided by financing activities for the three months ended March 31, 2020.  Cash provided by financing activities was approximately $7,654,000 for the three months ended March 31, 2019, which consisted of net proceeds from our underwritten offering in January 2019.

Contractual Obligations

We have a variety of contractual obligations, as more fully described in the 2019 Form 10-K.  These obligations include, but are not limited to, contractual obligations in connection with license agreements (including related milestone payments), lease payments, employee compensation and incentive program expenses, and contracts with various vendors for services.  As of March 31, 2020, the total estimated cost to complete our contracts with vendors for research and development services was approximately $800,000 under the terms of the applicable agreements.  All of these agreements may be terminated by either party upon appropriate notice as stipulated in the respective agreements.

Item 3.
Quantitative and Qualitative Disclosures About Market Risk.

Not required.

Item 4.
Controls and Procedures.

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective such that the information required to be disclosed by us in reports filed under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s (the “SEC’s”) rules and forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure. A controls system cannot provide absolute assurance, however, that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II.
Other Information

Item 1A.
Risk Factors.

Investing in our stock involves a high degree of risk.  You should carefully consider the following discussion of risk factors in its entirety. In addition to the other information set forth in this report, you should carefully consider the factors set forth in the Risk Factors section of our 2019 Form 10-K, as well as other information contained in the 2019 Form 10-K and in other reports we file with the SEC.

Our business is subject to risks arising from the ongoing COVID-19 pandemic.

The outbreak of COVID-19, which the World Health Organization declared a pandemic in March 2020, has spread across the globe and has led to disruption in the global economy and the biopharmaceutical industry. COVID-19 poses the risk that we or our employees, licensees, and other partners may be prevented from or restricted in conducting business activities for an indefinite period of time, including due to spread of the disease within these groups or due to restrictions on business and social distancing guidelines that may be requested or mandated by governmental authorities. We have reduced our headcount to five employees and are dependent on the efforts of our President and Chief Executive Officer, Douglas J. Swirsky, and other key professionals. The loss of Mr. Swirsky or any of our other key professionals as a result of illness or otherwise in connection with the COVID-19 pandemic could materially and adversely affect our business and our prospects. In addition, as the COVID-19 pandemic continues to disrupt the economy, our future access to capital on favorable terms and our ability to enter into and complete a strategic transaction may be adversely impacted.
 
The extent to which the COVID-19 pandemic impacts our business, financial condition and results of operations as well as on our ability to enter into and consummate a strategic transaction is highly uncertain and will depend on various factors, including the duration and scope of the pandemic, restrictions on business and social distancing guidelines that may be requested or mandated by governmental authorities, the other actions that may be taken to contain its impact, and impacts on our ability or the ability of potential strategic partners to access the markets on favorable terms, or at all.

i.
New IP. Any New IP developed, conceived or generated solely by Biosense after the Amendment Effective Date shall be owned and vest in Biosense. Biosense shall own all right, title, and interest in and to any New IP invented or developed using the Licensed IP and Rexahn Materials.
 

j.
Licensed IP.  Following the Amendment Effective Date (and as a result of giving effect to this Amendment No. 2), the term Rexahn Patents shall include any patents transferred to Biosense as a result of this Amendment No. 2.
 

k.
Personnel Support. Within [***] days after the Amendment Effective Date, Rexahn shall provide the contact information of the Key Employees of Rexahn as set out in Schedule 2.k. to BioSense so that BioSense, if it determines necessary, may use its reasonable efforts to establish consulting arrangements if these employees terminate their employment with Rexahn, except Rexahn shall have no obligation whatsoever to procure any such consulting arrangements for the benefit of Biosense. Rexahn shall waive any non-compete, confidentiality, and IP ownership obligations of the Key Employees solely to the extent related to RX-3117, which may conflict with or restrict those employees from entering into consulting agreements with Biosense after those employees terminate their employment relationship with Rexahn.
 

l.
Non-compete and Rights for other territories.
 

i.
Rexahn irrevocably and unconditionally agrees with and undertakes to BioSense that, unless with prior written consent of BioSense, during the Term of this Agreement and [***] years thereafter, Rexahn shall not, within the Territory (1) engage in research, development or commercialization of any Licensed Product or structurally-related nucleoside analogue that is activated primarily by UCK-2 dependent phosphorylation (“Restricted Products”); or (2) market or sell any Restricted Products in the Territory; or (3) authorize other parties to do so in the Territory.
 

ii.

5


m.
New Materials.  Any new project documents (including study results, regulatory documents etc.) created by BioSense after the Effective Dates will be solely owned by BioSense.  These new project documents may be used to support the development or registration of RX-3117 in the Territory by Biosense, and in other markets under the authorization of BioSense with appropriate financial terms to be discussed and agreed by BioSense, and the party interested in obtaining the information.
 

n.

i.
Article 2 of the Agreement shall be deleted in its entirety.


ii.
Article 3 of the Agreement shall be deleted in its entirety, because, among other reasons, the Parties no longer require a Joint Steering Committee for the Parties to perform their respective obligations under the Agreement.  To the extent any provision of Article 3 of the Agreement is referenced in any other portion of the Agreement (e.g., certain definitions, the operation of the Joint Steering Committee and the roles and responsibilities of Alliance Managers), then those portions of the Agreement shall be deemed to be deleted from the Agreement if not otherwise deleted, modified, waived or amended by this Amendment No. 2.


iii.
Section 4.4 of this Agreement shall be deleted in its entirety.

6

Subject to the provisions of this Section 5.2, BioSense shall have sole decision making authority for all matters related to the development, manufacturing and commercialization of RX-3117 in its territory from and after the Amendment Effective Date. Without prejudice to the rights of Rexahn hereunder, BioSense will provide a written explanation to Rexahn when there are decisions made by BioSense that result in not achieving the milestones with respect to RX-3117 set forth in this Section 5.2.


3.
Section 5.4 is deleted in its entirety.


4.
Section 5.5.2 is deleted in its entirety.


v.

7


vi.
Article 13 of the Agreement shall be amended as follows:


1.
The “proviso” in the last sentence of Section 13.1 shall be deleted, because the corresponding provision of Section 3.1.4 of the Agreement has been deleted.


2.
All other provisions of Article 13 shall apply with respect to the resolution of disputes under this License and Assignment Agreement.

3.    Effectiveness.  This Amendment No. 2 shall be effective from and after the Amendment Effective Date.
 
4.    No Other Amendments.  Except as modified by this Amendment No. 2 or as the context of this Amendment No. 2 may require, the Agreement shall remain in full force and effect, enforceable in accordance with its terms.
 
5.    Governing Law.  This Amendment and any dispute arising from the performance or breach hereof shall be governed by and construed and enforced in accordance with the laws of the State of New York without reference to conflicts of laws principles which would direct the application of the laws of another jurisdiction.
 
6.    Severability.  If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction.
 
7.   Release.  As a condition to Rexahn entering into this Amendment No. 2., Biosense, for itself and its affiliated companies, predecessors, successors, representatives, stockholders, directors, trustees, officers, employees, assigns and anyone claiming by, through or under the foregoing (each, a “Biosense Releasing Party”), hereby irrevocably, unconditionally and completely releases, acquits and forever discharges Rexahn, and its successors, representatives, stockholders, directors, officers, employees and assigns (each, a “Rexahn Released Party”), from and against, and hereby irrevocably, unconditionally and completely waives and relinquishes all past, present and future disputes, claims, controversies, demands, rights, obligations, liabilities, actions and causes of action of every kind and nature (collectively, “Claims”) that a Biosense Releasing Party may have had in the past, may now have or may have in the future, whether directly or indirectly, against any Rexahn Released Party arising out of or related to the Agreement prior to the Amendment Effective Date, whether such Claims are based in tort or contract, or are brought under law or in equity.
 
8.    Counterparts.  This Amendment may be signed in counterparts, each and every one of which shall be deemed an original, notwithstanding variations in format or file designation which may result from the electronic transmission, storage and printing of copies of this Agreement from separate computers or printers. Facsimile signatures and signatures transmitted via PDF shall be treated as original signatures.
 
9.    Successors and Assigns. This Amendment shall be binding upon and shall inure to the benefit of the Parties hereto and their respective successors and permitted assigns (including acquirer of Rexahn).
