1.Operations and Organization

Operations
Rexahn Pharmaceuticals, Inc. (the “Company”), a Delaware corporation, is a biopharmaceutical company whose principal operations are the discovery, development and commercialization of innovative treatments for cancer.  The Company had an accumulated deficit of $136,726,249$163,909,446 at September 30, 2017March 31, 2020 and anticipates incurring losses through fiscal year 2017in the foreseeable future.  In September 2019, the Company commenced a process to explore and beyond.  The Company has not yet generated commercial revenuesevaluate strategic alternatives to enhance shareholder value and has funded its operating lossesengaged a financial advisory firm to date throughassist in the sale of shares of its common stock and warrants to purchase shares of its common stock, convertible debt, interest income from cash, cash equivalents and marketable securities, and proceeds from reimbursed research and development costs.  process.

The Company believes that its cash and cash equivalents and marketable securitiesof 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.  Management believes it has the capability of managing the Company’s operations within existing cash available by focusing on select research and development activities, selecting projects in conjunction with potential financings and milestones, and efficiently managing the Company’s general and administrative affairs.

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 September 30, 2017March 31, 2020 and December 31, 20162019 and of the results of operations, and comprehensive loss, for the three and nine months ended September 30, 2017 and 2016stockholders’ equity and cash flows for the ninethree months ended September 30, 2017March 31, 2020 and 20162019 have been included.  Operating results for the three and nine months ended September 30, 2017March 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, 2017.2020. 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, 20162019 (the “2016“2019 Form 10-K”).  Information included in the condensed balance sheet as of December 31, 20162019 has been derived from the Company’s audited financial statements for the year ended December 31, 20162019 included in the 20162019 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.Recent Accounting Pronouncements Affecting the Company
Revenue from Contracts with Customers

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers,” a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The standard’s core principle is that a company should recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services, and provides a revenue recognition framework in accordance with this principle.  On August 12, 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09 by one year to December 15, 2017 for annual reporting periods beginning after that date and interim periods therein.  The Company expects to adopt this standard for the annual reporting period beginning January 1, 2018.   As the Company currently does not have revenue, contracts the Company does not expect the adoption of this standard to have a material impact on the operating results of the Company.

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases,” which requires an entity to recognize assets and liabilities arising from leases on the balance sheet and to provide additional disclosures about leasing arrangements.  ASU 2016-02 will be effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact the adoption of this guidance will have on its financial statements.

Compensation-Stock Compensation

In March 2016, the FASB issued ASU 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share Based Payment Accounting,” which includes multiple provisions intended to simplify various aspects of accounting for share-based payments.  The guidance is effective for reporting periods beginning after December 15, 2016, with early adoption permitted.  The Company adopted this guidance for the three months ended March 31, 2017.  This pronouncement did not have a material impact on the financial statements.

3.Marketable Securities

Marketable securities are considered “available-for-sale” in accordance with FASBFinancial 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 September 30, 2017 and December 31, 2016:

The Company typically invests in highly-rated securities, with the primary objective of minimizing the potential risk of principal loss.  As of September 30, 2017, the Company had three investments of commercial paper with an aggregate fair value of $3,228,583 and unrealized losses of $1,983, and 11 corporate bonds with an aggregate fair value of $11,249,968 and unrealized losses of $12,124 all of which have been unrealized losses for less than 12 months.  The Company does not intend to sell its marketable securities in an unrealized loss position.  Based upon these securities’ fair value relative to the cost, high ratings, and volatility of fair value, the Company considers the declines in market value of its marketable securities to be temporary in nature, does not consider any of its investments other-than-temporarily impaired, and anticipates that it will recover the entire amortized cost basis.2019:

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.

7.Deferred Research and Development Arrangement
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.
 
Rexgene BiotechZhejiang HaiChang Biotechnology Co., Ltd.
 
In 2003,On February 8, 2020, the Company entered into a collaborative researchan exclusive license agreement (the “HaiChang License Agreement”) with Rexgene BiotechZhejiang HaiChang Biotechnology Co., Ltd. (“Rexgene”HaiChang”) pursuant to which the Company granted HaiChang an exclusive (even as to the Company), a shareholder.  Rexgene is engaged in the development ofroyalty-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 AsiaAsia), 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 assistuse 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 research, developmentlow tens with respect to RX-0201 and clinical trials necessary for registrationRX-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 Company’s drug candidate Archexin® in Asia.  This agreement provides Rexgene with exclusive rightsforegoing milestones and royalties to license, sublicense, make, have made, use, sellthe extent relating to such compound(s) and import Archexin in Asia.  In accordance with the agreement, Rexgene paidjurisdiction, HaiChang will pay the Company a one-time feepercentage of $1,500,000any sublicensing revenue received by HaiChang, provided that in 2003.  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 agreement terminatesCompany 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 latercontract outset and as of 20 years or the term of the patent.  The amortization reduces research and development expenses for the periods presented.March 31, 2020.

The Company is using 20 years as its basis for recognition and accordingly, research and development expenses were reduced by $18,750 for each of the three month periods ended September 30, 2017 and 2016 and $56,250 for each of the nine month periods ended September 30, 2017 and 2016.  The remaining $393,750 and $450,000 to be amortized at September 30, 2017 and December 31, 2016, respectively, is reflected as a deferred research and development arrangement on the balance sheet.  The payment from Rexgene is being used in the cooperative funding of the costs of development of Archexin. Royalties of 3% of net sales of licensed products will become payable by Rexgene to the Company on a quarterly basis once commercial sales of Archexin begin in Asia.  The product is still under development and commercial sales in Asia are not expected to begin until at least 2018.

9.7.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 September 30, 2017March 31, 2020 and December 31, 2016,2019, there were stock options, restricted stock units and warrants to acquire, in the aggregate, 7,166,2092,070,511 and 7,142,7282,126,063 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.

At September 30, 2017March 31, 2020, the weighted average remaining contractual life of the outstanding warrants was 3.83.4 years.

The warrants issued to investors in the December 2012, November 2015, March 2016 and September 2016 offerings contain a provision for net cash settlement in the event of a fundamental transaction (contractually defined to include a merger, sale of substantially all assets, tender offer or share exchange).  Pursuant to the November 2015, March 2016, and September 2016 warrants, if fundamental transaction occurs, then the warrant holder has the option to receive cash, equal to the fair value of the remaining unexercised portion of the warrant.  The option is available to holders of the December 2012 warrants only if the consideration issued in the fundamental transaction consists of cash or stock in a non-public company.  Due to these contingent redemption provisions, the warrants require liability classification in accordance with ASC 480, “Distinguishing Liabilities from Equity,” and are recorded at fair value.   The June 2017 warrants contain a provision that allows the holder to opt for cash settlement in a fundamental transaction that was approved by, or required to be approved by, the board of directors of the Company. All of the Company’s outstanding warrants provide the holder the option as to the type of consideration received if the holders of common stock receive an option as to their consideration. In addition, all of the Company’s outstanding warrants contain a cashless exercise provision that is exercisable only in the event that a registration statement is not effective. That provision may not be operative if an effective registration statement is not available because an exemption under the U.S. securities laws may not be available to issue unregistered shares.  As a result, net cash settlement may be required, and the warrants require liability classification.

ASC 820, “Fair Value Measurements and Disclosures,” provides requirements for disclosure of liabilities that are measured at fair value on a recurring basis in periods subsequent to the initial recognition.  Fair values for warrants were determined using the Binomial Lattice (“Lattice”) valuation technique. The Lattice model provides for dynamic assumptions regarding volatility and risk-free interest rates within the total period to maturity. Accordingly, within the contractual term, the Company provided multiple date intervals over which multiple volatilities and risk free interest rates were used. These intervals allow the Lattice model to project outcomes along specific paths that consider volatilities and risk free rates that would be more likely in an early exercise scenario.

Significant assumptions are determined as follows:
Trading market values—Published trading market values;
Exercise price—Stated exercise price;
Term—Remaining contractual term of the warrant;
Volatility—Historical trading volatility for periods consistent with the remaining terms; and
Risk-free rate—Yields on zero coupon government securities with remaining terms consistent with the remaining terms of the warrants.

Due to the fundamental transaction provision, which could provide for early redemption of the warrants, the model also considered the probability the Company would enter into a fundamental transaction during the remaining term of the warrant. Because the Company is not yet achieving positive cash flow, management believes the probability of a fundamental transaction occurring over the term of the warrant is unlikely and therefore estimates the probability of entering into a fundamental transaction to be 5%.  For valuation purposes, the Company also assumed that if such a transaction did occur, it was more likely to occur towards the end of the term of the warrants.

The significant unobservable inputs used in the fair value measurement of the warrants include management’s estimate of the probability that a fundamental transaction may occur in the future.  Significant increases (decreases) in the probability of occurrence would result in a significantly higher (lower) fair value measurement.

15.12.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; and
   
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.

We are a clinical stage biopharmaceutical company dedicateddeveloping 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 discovery,“License and Assignment Agreement”) with BioSense Global LLC (“BioSense”) to advance the development and commercialization of innovative treatmentsRX-3117 for cancer. Our mission isall 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 improvedevelop and commercialize pharmaceutical products containing RX-3117 as a single agent for all human uses in the livesTerritory and assign and transfer to BioSense all of cancer patients by developing next-generation cancer therapies thatour 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 designedeligible to maximize efficacy while minimizingreceive milestone payments in an aggregate of up to $84.5 million upon the toxicityachievement of development, regulatory and side effects traditionally associated with cancer treatment. Our clinical pipeline features three oncology product candidatescommercial goals and will also be eligible to receive tiered royalties in Phase II clinical development and additional compoundsthe mid-single digits to low tens on annual net sales in pre-clinical development. Our strategy is to continue building a significant pipelinethe Territory.

RX-3117 is a small molecule nucleoside compound that we believe has therapeutic potential in a broad range of cancers, including pancreatic, bladder, colon, and lung cancer. RX-3117 is being evaluated as monotherapy in a multi-center Phase IIa clinical trial in metastatic pancreatic cancer in patients who are refractory to, or have relapsed after, multiple prior rounds of chemotherapy.  We are also planning to evaluate RX-3117 in combination with Abraxane® (nab-paclitaxel) as first line treatment in patients who are newly-diagnosed with metastatic pancreatic cancer and have not had prior cytotoxic treatment.  In 2016, we commenced enrollment in another Phase IIa trial in patients with locally advanced or metastatic bladder cancer.  This Phase IIa clinical trial is a multi-center open label, single agent study of RX-3117 being conducted at 10 clinical centers in the United States.  RX-3117 has received orphan drug designation from the U.S. Food and Drug Administration (the “FDA”) for pancreatic cancer.  Orphan drug designation in the United States provides tax incentives for clinical research and a waiver from user fees under certain circumstances. In addition, an orphan drug generally receives seven years of exclusivity after approval for a designated use, during which period the FDA generally cannot approve another product with the same active moiety for the same indication.  Rexahn has also received a positive opinion from the European Medicines Agency recommending orphan drug designation in pancreatic cancer.

Supinoxin, or RX-5902 is a potential first-in-class small molecule inhibitormodulator of phosphorylated-p68, a protein that we believethe Wnt/beta-catenin pathway which plays a key role in cancer cell growth, progressionproliferation and metastasis through its interactiontumor growth.  In August 2018, we entered into a Clinical Trial Collaboration and Supply Agreement (the “Collaboration Agreement”) with beta-catenin. In February, 2017 we initiatedMerck Sharp & Dohme B.V. (“Merck”) to evaluate the combination of RX-5902 and Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) in a Phase IIa clinical study of Supinoxin2 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.


·
ArchexinRX-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.  Archexin has received orphan drug designation from the FDA for renal cell carcinomaRX-0301 is currently in preclinical development by Zhejiang HaiChang Biotechnology Co., Ltd. (“RCC”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), glioblastoma, ovarian cancer, stomach cancerroyalty-bearing, sublicensable worldwide license to research, develop and pancreatic cancer. We are currently conductingcommercialize 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 IIa2a proof-of-concept clinical trial of Archexin in patients with metastatic renal cell carcinoma to evaluate its safety and efficacy in combination with AFINITOR® (everolimus).hepatocellular carcinoma.

Since our inception, our efforts and resources have been focused primarily on developing our pharmaceutical technologies, raising capital and recruiting personnel.  We have no product sales to date, and we will not generate any product sales until we receive approval from the FDA or equivalent foreign regulatory bodies to begin selling our pharmaceutical candidates.  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 investorsalternatives to enhance shareholder value, and partners.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.

Results of Operations

Comparison of the Three and Nine Months Ended September 30, 2017March 31, 2020 and September 30, 2016March 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 and nine months ended September 30, 2017 or 2016.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 increaseddecreased approximately $155,000,$440,000, or 10.9%25.9%, to $1,574,000approximately $1,256,000 for the three months ended September 30, 2017March 31, 2020 from $1,419,000$1,696,000 for the three months ended September 30, 2016.  General and administrative expenses increased approximately $515,000, or 11.4%, to $5,005,000 for the nine months ended September 30, 2017 from $4,490,000 for the nine months ended September 30, 2016.March 31, 2019.  The increasesdecreases were primarily attributable to higherdecreased personnel and operating costs and professional fees in 2017.resulting from the streamlining of operations.
Research and Development Expenses

Research and development expenses increased approximately $346,000, or 15.1%,costs are expensed as incurred.  These costs consist primarily of salaries and related personnel costs, and amounts paid to $2,645,000contract research organizations, hospitals and laboratories for the three months ended September 30, 2017, from $2,299,000provision of services and materials for the three months ended September 30, 2016.  drug development and clinical trials.  Our research and development expenses are currently related to our oncology drug candidates.

Research and development expenses decreased approximately $552,000,$1,785,000, or 6.9%79.6%, to $7,452,000approximately $457,000 for the ninethree months ended September 30, 2017,March 31, 2020, from $8,004,000approximately $2,242,000 for the ninethree months ended September 30, 2016.  In both the three and nine-month periods ended September 30, 2017, we experienced increased clinical trial costs compared to the prior year periods, partially offset by a decrease in personnel expenses.  In the three-month period ended September 30, 2017, a new drug manufacturing campaign that began in the third quarter together with the increased clinical trial costs contributed to the overall increase in research and development expenses in the period.  Conversely, the increased clinical trial costs in the nine-month period ended September 30, 2017 were more than offset by lower drug manufacturing costs as a result of supplies that were available from earlier manufacturing campaigns.  During the nine months ended September 30, 2017, we incurred approximately $1,324,000 of drug manufacturing costs, primarily asMarch 31, 2019.  The decreases are a result of the drug manufacturing campaign that began in the third quarter, compared to approximately $2,325,000 during the nine months ended September 30, 2016, primarily from large manufacturing campaigns in the early months of 2016.  Because the volume and timingcompletion of our drug manufacturing does not correlate directly with the levelRX-3117 and timing of clinical trial activity, we expect expenses related to drug manufacturing costs to vary from period to period based not only on the progress of clinical trials, but also when we engage in manufacturing activities.  We expect research and development expenses to increase in the remaining quarter of 2017 compared to the quarter ended September 30, 2017 due to continued patient enrollment in ourRX-5902 clinical trials, and newdecreased drug manufacturing campaigns.costs.

The table below summarizes the approximate amounts incurred in each of our research and development projects for the three and nine months ended September 30, 2017March 31, 2020 and 2016:2019:

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 increaseddecreased approximately $35,000 and $51,000$47,000, or 132.4% and $61.3%, respectively57.7% for the three and nine months ended September 30, 2017, respectively,March 31, 2020, compared to the same periodsperiod in 2016.2019.  The increasesdecreases were primarily attributable to higher aggregatelower interest rates and balances of cash, and cash equivalents and marketable securities and higher interest rates on marketable securities for the three and nine months ended September 30, 2017March 31, 2020 compared to the same periodsperiod in 2016.2019.
Unrealized (Loss) Gain (Loss) 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 September 30, 2017March 31, 2020 and 2016,2019, we recorded unrealized (losses) gains on the fair value of our warrants of approximately $3,121,000$(58,000) and $968,000.  During the nine months ended September 30, 2017, we recorded unrealized (losses) gains on the fair value of warrants of approximately ($9,048,000) and $3,942,000$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 September 30, 2017March 31, 2019 primarily resulted from a significant decrease in the stock price of the underlying common stock at September 30, 2017the end of this period compared to June 30, 2017.  The large unrealized loss for the nine months ended September 30, 2017 primarily resulted from a significant increase in the stock pricebeginnings of the underlying common stock at September 30, 2017 compared to December 31, 2016.  An increase in volatility of the common stock during that period and the large number of outstanding warrants also had an impact on the large unrealized loss for the nine months ended September 30, 2017.

Financing Expense

We incurred approximately $333,000 and $313,000 of financing expenses during the nine months ended September 30, 2017, and 2016, respectively related to our registered direct offerings in June 2017, September 2016 and March 2016.  We incurred approximately $143,000 of financing expenses during the three months ended September 30, 2016, related to our registered direct offering in September 2016.  We did not incur financing expenses during the three months ended September 30, 2017.this period.

Net Loss

As a result of the above, net loss for the three and nine months ended September 30, 2017March 31, 2020 was approximately $1,038,000 and $21,702,000,$587,000 or $0.04 and $0.83$0.15 per share, respectively, compared to approximately $2,867,000 and $8,782,000,$2,343,000, or $0.13 and $0.42 per share, respectively,$0.62 for the three and nine months ended September 30, 2016.  As previously discussed, included in the net loss for the three and nine months ended September 30, 2017 are non-cash charges of approximately $3,121,000 and ($9,048,000) in unrealized gains (losses) on the fair value of warrants, compared to unrealized gains of $968,000 and $3,942,000 for the three and nine months ended September 30, 2016.
Research and Development ProjectsMarch 31, 2019.

Research and development costs are expensed as incurred.  These costs consist primarily of salaries and related personnel costs, costs to acquire pharmaceutical products and product rights for development and amounts paid to contract research organizations, hospitals and laboratories for the provision of services and materials for drug development and clinical trials.  Costs incurred in obtaining the license rights to technology in the research and development stage that have no alternative future uses are expensed as incurred.  Our research and development programs are related to our oncology clinical stage drug candidates, RX-3117, Supinoxin and Archexin, and our pre-clinical stage drug candidate, RX-21101.  As we expand our clinical studies, we expect to enter into additional development agreements.  Significant additional expenditures will be required if we complete our clinical trials, start new trials, apply for regulatory approvals, continue development of our technologies, expand our operations and bring our products to market.  The eventual total cost of each clinical trial is dependent on a number of uncertainties such as trial design, the length of the trial, the number of clinical sites and the number of patients.  The process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive and uncertain.  Because the successful development of our most advanced drug candidates, RX-3117, Supinoxin and Archexin, is uncertain, and because RX-21101 is in early-stage development, we are unable to estimate the costs of completing our research and development programs, the timing of bringing such programs to market and, therefore, when material cash inflows could commence from the sale of these drug candidates, if any.  If these projects are not completed as planned, our results of operations and financial condition would be negatively affected.

RX-3117
 RX-3117 is a novel, investigational oral small molecule nucleoside compound.  We believe RX-3117 has therapeutic potential in a broad range of cancers including pancreatic, bladder, cervical, non-small cell lung cancer and colon cancer.  We previously identified the MTD of RX-3117, which we are evaluating in Phase IIa proof-of-concept clinical trials in patients with relapsed or refractory metastatic pancreatic cancer and patients with locally advanced or metastatic bladder cancer.

Expenses related to RX-3117 increased during the three and nine months ended September 30, 2017 compared to the same period in 2016 due to increased clinical trial and patient enrollments resulting from the progression of our pancreatic and bladder cancer clinical trials, as well as manufacturing costs for new campaigns. We expect that expenses related to RX-3117 will increase in the remainder of 2017 compared to the three and nine months ended September 30, 2017 due to patient enrollment costs, continued manufacturing costs for new campaigns, and the commencement of a combination Phase IIa clinical trial with Abraxane in pancreatic cancer.

Supinoxin (RX-5902)
Supinoxin is a potential first-in-class small molecule inhibitor of phosphorylated p68, a protein that we believe plays a key role in cancer growth, progression and metastasis through its interaction with beta-catenin. Phosphorylated p68 results in up-regulation of cancer-related genes and a subsequent proliferation of cancer cells and tumor growth.  In February 2017, we initiated a Phase IIa clinical study of Supinoxin in patients with metastatic TNBC.

Expenses related to Supinoxin decreased during the three and nine months ended September 30, 2017 compared to the three and nine months ended September 30, 2016.  The decrease is primarily attributable to decreased manufacturing costs due to a significant supply of drug product already available from earlier manufacturing campaigns.  However, we expect that expenses related to Supinoxin will increase in the remainder of 2017 compared to the three and nine months ended September 30, 2017 due to patient enrollment costs associated with our Phase IIa trial in patients with metastatic TNBC and new manufacturing campaigns.
Archexin

Archexin is a potential best-in-class, potent inhibitor of the protein kinase Akt-1, which we believe plays a critical role in cancer cell proliferation, survival, angiogenesis, metastasis and drug resistance.  We are currently conducting a Phase IIa proof-of-concept clinical trial of Archexin in patients with metastatic RCC to evaluate its safety and efficacy in combination with AFINITOR (everolimus).

Expenses related to Archexin decreased during the three and nine months ended September 30, 2017 compared to the same periods in 2016.  The decrease is primarily attributable to decreased manufacturing costs due to a significant supply of drug product already available.  We expect that expenses related to Archexin will remain flat for the remainder of 2017 compared to the three and nine months ended September 30, 2017 as we continue the ongoing Archexin clinical trial.

Expenses related to our pre-clinical candidates increased for the three and nine months ended September 30, 2017 compared to the same periods in 2016 primarily as a result of increased research activities.  We expect that expenses related to our pre-clinical pipeline, including RX-21101, will remain flat for the remainder of 2017 compared to the three and nine months ended September 30, 2017 as we continue testing and development.

Research and Development Process
We have engaged third-party contract research organizations and other investigators and collaborators, such as universities and medical institutions, to conduct our pre-clinical studies, toxicology studies and clinical trials.  Engaging third-party contract research organizations is typical practice in our industry. However, relying on such organizations means that the clinical trials and other studies described above are being conducted at external locations and that the completion of these trials and studies is not within our direct control. Trials and studies may be delayed due to circumstances outside our control, and such delays may result in additional expenses for us.
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.

There was no cash provided by financing activities for the three months ended March 31, 2020.  Cash provided by financing activities was approximately $14,673,000$7,654,000 for the ninethree months ended September 30, 2017, which consisted of net proceeds of $9,241,000 from our registered direct public offering in June 2017 and $5,354,000 and $78,000 from the exercise of stock warrants and options, respectively.  Cash provided by financing activities was approximately $10,122,000 for the nine months ended September 30, 2016,March 31, 2019, which consisted of net proceeds from our registered direct public offeringsunderwritten offering in March 2016 and September 2016.

After September 30, 2017, on October 17, 2017, we closed a registered direct public offering of 3,265,309 shares of common stock and warrants to purchase up to 1,632,654 shares of common stock, resulting in gross proceeds to us of approximately $8,000,000.January 2019.

Contractual Obligations

We have a variety of contractual obligations, as more fully described in our 2016the 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 September 30, 2017,March 31, 2020, the total estimated cost to complete our contracts with vendors for research and development services was approximately $10,750,000$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.

Current and Future Financing Needs

We have incurred negative cash flow from operations since we started our business.  We have spent, and 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.  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.  There can be no assurance that additional capital will be available when needed or on terms satisfactory to us, if at all.  If we are not able to raise sufficient additional capital, we will have to reduce our research and development activities. We believe our cash, cash equivalents, and marketable securities will be sufficient to cover our cash flow requirements for our current activities for at least the next 12 months from the date these financial statements were issued.

The actual amount of funds we will need to operate is subject to many factors, some of which are beyond our control.  These factors include the following:

·the progress of our product development activities;

·the number and scope of our product development programs;

·the progress of our pre-clinical and clinical trial activities;

·the progress of the development efforts of parties with whom we have entered into collaboration agreements;
·our ability to maintain current collaboration programs and to establish new collaboration arrangements;

·the costs involved in prosecuting and enforcing patent claims and other intellectual property rights; and

·the costs and timing of regulatory approvals.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements or holdings in variable interest entities.

Controls and Procedures.

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”)principal executive officer and Chief Financial Officer (“CFO”),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)Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based upon that evaluation, our CEOprincipal executive officer and CFOprincipal 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 CEOprincipal executive officer and CFO,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 Overover Financial Reporting

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 20162019 Form 10-K, as well as other information contained in the 20162019 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, disclosed inincluding 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 2016 Form 10-K.ability or the ability of potential strategic partners to access the markets on favorable terms, or at all.
