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 and other medical needs.  The Company had an accumulated deficit of $ 98,838,179 at June 30, 2015 and anticipates incurring losses through fiscal year 2015 and beyond.  The Company has not yet generated commercial revenues and has funded its operating losses to date through the sale of shares of its common stock and warrants to purchase shares of its common stock, convertible debt, financings, interest income from cash, cash equivalents and marketable securities, and proceeds from reimbursed research and development costs.  The Company believes that its cash, cash equivalents, and marketable securities, will be sufficient to cover its cash flow requirements for its current activities for at least the next 12 months.  Management believes it has the capability of managing the Company’s operations within existing cash and marketable securities available by focusing on select research and development activities, selecting projects in conjunction with potential financings and milestones, and efficiently managing its 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 June 30, 2015 and December 31, 2014 and of the results of operations and comprehensive income (loss) for the three and six months ended June 30, 2015, and cash flows for the six months ended June 30, 2015 and 2014 have been included.  Operating results for the three and six months ended June 30, 2015 are not necessarily indicative of results that may be expected for any other interim period or the full fiscal year ending December 31, 2015. 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, 2014 (the “2014 Form 10-K”).  Information included in the condensed balance sheet as of December 31, 2014 has been derived from the Company’s audited financial statements for the year ended December 31, 2014 included in the 2014 Form 10-K.

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.
 
Reclassification

Certain amounts in the prior year’s financial statements have been reclassified to conform to the current year’s presentation with no material effect on the financial statements.

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.  ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016 and interim periods therein.  On July 9, 2015, the FASB approved the deferral of the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date.  Early adoption of the standard is permitted, but not before the original effective date of December 15, 2016.  The Company is currently evaluating the impact that the adoption of this guidance will have on its financial statements and future operating results.

Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern

In August 2014, the FASB issued ASU 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” which requires management to perform interim and annual assessments as to the entity’s ability to continue as a going concern and provides related disclosure guidance.  ASU 2014-15 will be effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The Company is currently evaluating the impact the adoption of this guidance will have on its financial statements.

Marketable Securities

Marketable securities are considered “available-for-sale” in accordance with FASB Accounting Standard 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 following table shows the Company’s marketable securities’ adjusted cost, gross unrealized gains and losses, and fair value by significant investment category as of June 30, 2015 and December 31, 2014:

The Company typically invests in highly-rated securities, with the primary objective of minimizing the potential risk of principal loss.  As of June 30, 2015, the Company had three certificates of deposit in a loss position with a fair value of $719,957 and unrealized losses of $43 and two corporate bonds in a loss position with a fair value of $2,025,850 and unrealized losses of $1,585, all of which have been unrealized losses for less than 12 months.  The Company does not have the intent to sell its marketable securities in an unrealized loss position.  Based upon the Company’s 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 and does not consider any of its investments other-than-temporarily impaired, and anticipates that it will recover the entire amortized cost basis.

Deferred Research and Development Arrangement

Rexgene Biotech Co., Ltd.

In 2003, the Company entered into a collaborative research agreement with Rexgene Biotech Co., Ltd. (“Rexgene”), a shareholder.  Rexgene is engaged in the development of pharmaceutical products in Asia and has agreed to assist the Company with the research, development and clinical trials necessary for registration of the Company’s drug candidate Archexin in Asia.  This agreement provides Rexgene with exclusive rights to license, sublicense, make, have made, use, sell and import Archexin in Asia.  In accordance with the agreement, Rexgene paid the Company a one-time fee of $1, 500,000 in 2003.  The agreement terminates at the later of 20 years or the term of the patent.

The Company is using 20 years as its basis for recognition.  The amortization reduces research and development expenses for the periods presented. Research and development expenses were reduced by $18,750 and $37,500 for the three and six months ended June 30, 2015 and 2014, respectively.  The remaining $5 62,500 and $600,000 to be amortized at June 30, 2015 and December 31, 2014, respectively, are 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 2016.  Under the terms of the agreement, Rexgene does not   receive royalties on the Company’s net sales outside of Asia.

Deferred Lease Incentive

On June 29, 2009, the Company entered into a five-year office lease agreement, which is further discussed in Note 14.  The lessor agreed to grant a leasehold improvement allowance of $100,000 to the Company to be used for the construction cost of improvements to the leased property, which included architectural and engineering fees, government agency plan check, permit and other fees, sales and use taxes, testing and inspection costs and telephone and data cabling and wiring in the premises.  The Company accounted for the benefit of the leasehold improvement allowance as a reduction of rental expense over the five-year term of the office lease.

On June 7, 2013, the Company entered into the first amendment to the lease agreement, also discussed in Note 14. According to the terms of the amendment, the Company extended the lease term until June 30, 2019.  The lessor agreed to grant an additional leasehold improvement allowance of $54,660 to the Company to be used for further construction of the leased property, furniture and equipment.  The Company accounts for this benefit, including the unamortized portion from the original lease agreement, as a reduction of rental expense over the six-year amended term of the lease.

The following table sets forth the cumulative deferred lease incentive:

Deferred Office Lease Expense

The amended lease agreement provides for an initial annual base rent with annual increases over the next six years.  The Company recognizes rental expense on a straight-line basis over the term of the lease, which resulted in a deferred rent liability of $65,670 and $68,960 as of June 30, 2015 and December 31, 2014, respectively.

Net (Loss) Income per Common Share
 
Basic (loss) income per common share is computed by dividing net (loss) income by the weighted average number of shares of common stock outstanding for the period.  Diluted (loss) income per common share is computed by dividing net (loss) income by the weighted average number of shares of common stock outstanding, plus the number of common share equivalents that would be dilutive.  As of June 30, 2015 and December 31, 2014, there were stock options and warrants to acquire, in the aggregate, 26,011,686 and 24,606,677 shares of the Company’s common stock, respectively, that are potentially dilutive. However, diluted (loss) income per share for all periods presented is the same as basic (loss) income per share because the inclusion of common share equivalents would be anti-dilutive. The Company is not disclosing the number of weighted average diluted shares outstanding for the three months ended June 30, 2014 because the impact is immaterial.

On March 16, 2015, the Company entered into an at market issuance sales agreement (the “Sales Agreement”) with MLV & Co. LLC (“MLV”) pursuant to which the Company may issue and sell shares of its common stock having an aggregate offering price of up to $40 million from time to time, at its option, through MLV as its sales agent, subject to certain terms and conditions. Any shares sold will be sold pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-196255), as supplemented by a prospectus supplement dated March 16, 2015.  The Company will pay MLV a commission of 3.0% of the gross proceeds of the sale of any shares sold through MLV. For the six months ended June 30, 2015, the Company sold 1,407,072 shares of common stock pursuant to the Sales Agreement for $1,042,573 in gross proceeds at a weighted average price of $0.7410 per share.  Net proceeds to the Company were $1,005,715 after deducting commissions and other transaction costs.

During the six months ended June 30, 2015, option holders exercised stock options to purchase shares of the Company’s common stock for cash of $70 8,617 , and the Company issued 889,428 shares.

Stock-Based Compensation

As of June 30 2015, the Company had 1 2,805,815 options outstanding.

At the Company’s Annual Meeting of the Stockholders held on June 10, 2013, the Company’s stockholders voted to approve the Rexahn Pharmaceuticals, Inc. 2013 Stock Option Plan (the “2013 Plan”).  Under the 2013 Plan, the Company grants stock options to key employees, directors and consultants of the Company.  A total of 17,000,000 shares of common stock have been reserved for issuance pursuant to the 2013 Plan.  As of June 30, 2015, there were 6, 697,315 options outstanding under the 2013 Plan, and 1 0,295,185 shares were available for issuance from the 2013 Plan.

On August 5, 2003, the Company established a stock option plan (the “2003 Plan”).  Under the 2003 Plan, the Company granted stock options to key employees, directors and consultants of the Company.  With the adoption of the 2013 Plan, no new stock options may be issued under the 2003 Plan, but previously issued options under the 2003 Plan remain outstanding until their expiration.  As of June 30, 2015, there were 6,108,500 outstanding options under the 2003 Plan.

For the majority of the grants to employees under both the 2003 Plan and 2013 Plan, the vesting period is either (i) 30%, 30% and 40% on the first, second and third anniversaries of the grant date, respectively, or (ii) 25% each on the first four anniversaries.  Options expire between five and ten years from the date of grant. For grants to non-employee consultants of the Company, the vesting period is between one and three years, subject to the fulfillment of certain conditions in the individual stock agreements, or 100% upon the occurrence of certain events specified in the individual stock agreements.

Accounting for Awards

The Company’s results of operations for the three months ended June 30, 2015 and 2014 include stock-based compensation expense totaling $271,966 and $132,518 respectively.  The Company’s results of operations for the six months ended June 30, 2015 and 2014 include stock based compensation expense totaling $544,352 and $260,868, respectively. Such amounts have been included in the statement of operations in general and administrative and research and development expenses.  No income tax benefit has been recognized in the statement of operations for stock-based compensation arrangements as the Company has provided for a 100% valuation allowance on its deferred tax assets.

Stock option 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.

Summary of Stock Option Transactions

There were 3,726,316 stock options granted at exercise prices ranging from $0. 68 to $0. 89 with an aggregate fair value of $1, 835,853 during the six months ended June 30, 2015.  There were 1,398,499 stock options granted at exercise prices ranging from $ 0.90 to $1. 35 with an aggregate fair value of $ 1,073,810 during the six months ended June 30, 2014.

The fair value of options at the date of grant was estimated using the Black-Scholes option pricing model.  The Company took into consideration guidance under ASC 718, “Compensation-Stock Compensation” and Staff Accounting Bulletin No. 107 (“SAB 107”) when reviewing and updating assumptions.  The expected volatility is based upon historical volatility of the Company’s stock.  The expected term is based upon the simplified method as allowed under SAB 107.

The warrants issued to investors in the March 2011, December 2012 and previous offerings contain a provision for net cash settlement in the event that there is a fundamental transaction (contractually defined as a merger, sale of substantially all assets, tender offer or share exchange).  If a fundamental transaction occurs in which the consideration issued consists principally of cash or stock in a non-public company, then the warrant holder has the option to receive cash, equal to the fair value of the remaining unexercised portion of the warrant.  Due to this contingent redemption provision, the warrants require liability classification in accordance with ASC 480 and are recorded at fair value.  The warrants issued to investors in the July 2013, October 2013 and January 2014 offerings contain a fundamental transaction provision, but the warrant holders only have an option as to the type of consideration received if the holders of common stock receive an option as to their consideration.  In addition, the warrants issued in the July 2013, October 2013, January 2014 and previous offerings 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 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 are 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;
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.

Income Taxes

No provision for federal and state income taxes was required for the three and six months ended June 30, 2015 and 2014 due to the Company’s operating losses and increased deferred tax asset valuation allowance.  At June 30, 2015 and December 31, 2014, the Company had unused net operating loss carry-forwards of approximately $ 90,500,000 and $ 81,619,000 , respectively, which expire at various dates through 203 5 .  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 June 30, 2015 and December 31, 2014, 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.

Deferred tax assets and valuation allowances consist of:

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.  There have been no changes in the methodologies used at June 30, 2015 and December 31, 2014.

The fair value of the Company’s Level 2 marketable securities is determined by using quoted prices from independent pricing services that use market data for comparable securities in active or inactive markets.  A variety of data inputs, including benchmark yields, interest rates, known historical trades and broker dealer quotes are using with pricing models to determine the quoted prices.

The fair value methodology for the warrant liabilities is disclosed in Note 12.

The carrying amounts reported in the financial statements for cash and cash equivalents (Level 1), prepaid expenses and other assets, and accounts payable and accrued expenses approximate fair value because of the short term maturity of these financial instruments.

The following table sets forth a reconciliation of changes in the three months ended June 30, 2015 and 2014 in the fair value of the liabilities classified as Level 3 in the fair value hierarchy:

Additions consist of the fair value of warrant liabilities upon issuance.  Transfers out of Level 3 for warrant liabilities consist of warrant exercises, where the liability is converted to additional paid-in capital upon exercise.  The Company’s policy is to recognize transfers in and transfers out as of the actual date of the event or change in circumstance that caused the transfer.
 
Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

The following discussion should be read in conjunction with the unaudited condensed financial statements and notes thereto set forth in Item 1 of this Quarterly Report on Form 10-Q and the audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2014.

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,” “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:

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

·
our drug candidates being in early stages of development, including in pre-clinical development;

·
our ability to initially develop drug candidates for orphan indications to reduce the time-to-market and take advantage of certain incentives provided by the U.S. Food and Drug Administration;

·
our ability to transition from our initial focus on developing drug candidates for orphan indications to candidates for more highly prevalent indications;

·
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 pre-clinical 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 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 our Annual Report on 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 dedicated to the discovery, development and commercialization of innovative new treatments for cancer and other serious medical conditions.  Our mission is to discover and develop new medicines for diseases that have significant unmet medical needs and no effective cures, particularly high-mortality cancers.  Our pipeline includes one oncology candidate currently in Phase II clinical trials, two oncology candidates currently in Phase I clinical trials, other compounds in preclinical development, and two drug candidates that are not being actively developed.  Our strategy is focused on building a significant product pipeline of innovative drug candidates that we will commercialize independently or with partners.  We intend to initially develop drug candidates for cancers that are orphan indications and then expand into more highly prevalent cancers.

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 U.S. Food and Drug Administration (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 strategic investors and partners.

Recently Issued Accounting Standards

In May 2014, 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.  ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016 and interim periods therein.  On July 9, 2015, the FASB approved the deferral of the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date.  Early adoption of the standard is permitted, but not before the original effective date of December 15, 2016.  We are currently evaluating the impact that the adoption of this guidance will have on our financial statements and future operating results.
 
In August 2014, the FASB issued ASU 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” which requires management to perform interim and annual assessments as to the entity’s ability to continue as a going concern and provides related disclosure guidance.  ASU 2014-15 will be effective for reporting periods beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact the adoption of this guidance will have on our financial statements.

Results of Operations
 
Comparison of the Three and Six Months Ended June 30, 2015 and June 30, 2014

Total Revenues

We had no revenues for the three and six months ended June 30, 2015 or 2014.

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 $222,677, or 12.3%, to $1,584,852 for the three months ended June 30, 2015 from $1,807,529 for the three months ended June 30, 2014. General and administrative expenses decreased $192,497, or 5.8%, to $3,109,552 for the six months ended June 30, 2015 from $3,302,049 for the six months ended June 30, 2014.  The year over year decrease is primarily attributable to a decrease in professional fees offset by an increase in personnel expenses.

Research and Development Expenses

Research and development expenses consist primarily of salaries and related personnel costs, fees paid to consultants and outside service providers for laboratory development and other expenses relating to the design, development, testing, and enhancement of our drug candidates.  We expense our research and development costs as they are incurred.

Research and development expenses increased $1,533,681, or 90.1%, to $3,235,088 for the three months ended June 30, 2015, from $1,701,407 for the three months ended June 30, 2014.  Research and development expenses increased $3,155,115, or 106.1%, to $6,128,096 for the six months ended June 30 2015, from $2,972,981 for the six months ended June 30, 2014.  The increase is attributable to the advancement of our drug candidates.  During the three and six months ended June 30, 2015, we incurred additional clinical trial and drug manufacturing costs as we have advanced our clinical trials for Archexin, RX-3117 and Supinoxin.  The increase is also partially attributable to an increase in personnel expenses.
 
The table below summarizes the approximate amounts incurred on each of our research and development projects for the three and six months ended June 30, 2015 and 2014:

Interest Income

Interest income decreased $11,015 or 29.0% to $27,020 for the three months ended June 30, 2015 from $38,035 for the three months ended June 30, 2014.  Interest income decreased $12,724 or 18.1% to $57,602 for the six months ended June 30, 2015 from $70,326 for the six months ended June 30, 2014.  The decrease is attributable to lower aggregate balances of cash, cash equivalents, and marketable securities for the three and six months ended June 30, 2015 compared to the three and six months ended June 30, 2014.

Unrealized 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 June 30, 2015 and 2014, we recorded unrealized gains on the fair value of our warrants of $1,558,760 and $3,665,365 respectively.  During the six months ended June 30, 2015 and 2014, we recorded unrealized gains (losses) on the fair value of our warrants of $1,674,175 and $(7,995,159) 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 warrant with related changes to external market factors. The unrealized loss for the six months ended June 30, 2014 primarily resulted from an increased stock price of the underlying common stock at June 30, 2014 and on the dates during the six months ended June 30, 2014 when warrant holders exercised their warrants.

Financing Expense

We incurred $206,172 of financing expenses during the six months ended June 30, 2014 related to our registered direct offering in January 2014.  We did not incur financing expenses for the three and six months ended June 30, 2015, or during the three months ended June 30, 2014.

Net (Loss) Income

As a result of the above, net (loss) income for the three and six months ended June 30, 2015 was ($3,234,160) and ($7,505,871) or ($0.02) and ($0.04) per share, respectively, compared to $194,464 and $(14,406,035) or $0.00 and $(0.08) per share, for the three and six months ended June 30, 2014, respectively.
 
Research and Development Projects

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, Archexin, RX-3117 and Supinoxin, and our pre-clinical stage drug candidate, RX-21101.  As we expand our clinical studies, we will 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, Archexin, RX-3117 and Supinoxin, 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.

Archexin ®

Archexin is a potential best-in-class, potent inhibitor of the protein kinase phosphorylated Akt-1, which is over-expressed in cancer cells and 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 carcinoma (“RCC”), glioblastoma, ovarian cancer, stomach cancer and pancreatic cancer.  That designation provides tax incentives for clinical research and a waiver of user fees.  In addition, a drug that is approved for its orphan-designated use receives seven years of exclusivity after approval, during which the FDA generally cannot approve another product with the same active moiety for the same indication.

 In August 2012, we announced top line results of an open label 2-stage Phase IIa clinical trial for Archexin that was designed to assess the safety and efficacy of Archexin in combination with gemcitabine.  Gemcitabine is used to treat pancreatic, breast, ovarian and lung cancers.  Gemcitabine is a member of a group of chemotherapy drugs known as anti-metabolites.  It prevents cells from making DNA and RNA, which stops cell growth and causes cells to die.  Stage 1 was the dose-finding portion of the study, and Stage 2 was the dose-expansion portion of the study using the dose identified in Stage 1 administered with gemcitabine.   The study enrolled 31 subjects aged 18 to 65 with metastatic pancreatic cancer at nine centers in the United States and India.  The primary endpoint was overall survival following four cycles of therapy with a six month follow-up.  For those evaluable patients, the study demonstrated that treatment with Archexin in combination with gemcitabine provided a median survival rate of 9.1 months compared to the historical survival data of 5.65 months for standard single agent gemcitabine therapy.  The most frequent reported adverse events were constipation, nausea, abdominal pain and pyrexia, regardless of relatedness.
 
We initiated a Phase IIa clinical proof-of-concept clinical trial of Archexin in January 2014 to study its safety and efficacy in patients with metastatic RCC. In the trial, Archexin will be administered in combination with everolimus (Afinitor®), and will be conducted in two stages.  The first stage will be dose ranging, with up to three dose groups with three RCC patients each, to determine the maximal tolerated dose (“MTD”) of Archexin in combination with everolimus.  Once the MTD has been determined, thirty RCC patients will be randomized to two treatment groups, either Archexin in combination with everolimus or everolimus alone, in a ratio of 2:1.  We plan to complete the initial safety component of this study in the second half of 2015.  Expenses related to Archexin increased for the three and six months ended June, 2015 compared to the same periods in 2014 due to patient enrollment activities.

RX-3117

RX-3117 is a novel, investigational small molecule nucleoside compound.  In preclinical models when activated (phosphorylated) by uridine-cytidine kinase 2 (“UCK2”), a protein that is overexpressed in various human cancer cells, RX-3117 is incorporated into DNA or RNA of cells and inhibits both DNA and RNA synthesis, which induces apoptotic cell death of tumor cells. We believe RX-3117 has therapeutic potential in a broad range of cancers including pancreatic, lung, bladder, cervical and colon cancer.  RX-3117 has received orphan drug designation from the FDA for the treatment of patients with pancreatic cancer.  RX-3117 has also been shown in animal models to inhibit the growth of gemcitabine-resistant human cancers and improve overall survival.  We completed an exploratory Phase I clinical study of RX-3117 in 2012 that showed a level of oral bioavailability of RX-3117 and no adverse effects reported in the study.

In January 2014, we initiated a Phase Ib clinical trial to study the safety, tolerability, dose-limiting toxicities and MTD of RX-3117 in patients with solid tumors.  Secondary endpoints will include characterizing the pharmacokinetic profile of RX-3117 and evaluating the preliminary anti-tumor effects of RX-3117.  Patient enrollment has been completed in eight dose groups (30mg, 60mg, 100mg, 150mg, 200mg, 500mg, 1,000mg and 1,500mg). The MTD of RX-3117 has not yet been achieved.  Given the robust preliminary safety profile observed in the Phase Ib clinical trial to date, it is difficult to predict when we will achieve the MTD and complete the clinical trial. We intend to present preliminary clinical findings from the ongoing Phase Ib clinical study during the third quarter of 2015.  RX-3117 continues to preliminarily demonstrate safety and tolerability, requiring higher dose levels than expected to be tested to achieve the MTD.  To date, no dose-limiting toxicities have been associated with RX-3117 treatment.  Based on the progress of the RX-3117 clinical development program and the level of interest expressed from a number of oncology-focused pharmaceutical companies, we are continuing discussions with multiple companies to explore collaborative business structures in an effort to maximize the potential value of the program.  Expenses related to RX-3117 increased for the three and six months ended June 30, 2015 as compared to the same periods in 2014 primarily due to additional drug manufacturing costs to support continuing enrollment in the clinical trial.

Supinoxin (RX-5902)

Supinoxin is a potential first-in-class small molecule that inhibits the phosphorylation of p68, a protein that we believe plays a key role in cancer growth, progression and metastasis. Phosphorylated p68, which is highly expressed in cancer cells, but not in normal cells, results in up-regulation of cancer-related genes and a subsequent proliferation of cancer cells and tumor growth.  Supinoxin selectively blocks phosphorylated p68, thereby decreasing the proliferation or growth of cancer cells.  In pre-clinical tissue culture models and in-vivo xenograft models, Supinoxin has demonstrated single-agent tumor growth inhibition, potential synergy with cytotoxic agents and activity against drug resistant cancer cells.  In particular, in in-vivo xenograft models of human triple negative breast cancer and pancreatic cancer, treatment with Supinoxin on days 1 to 20 in mouse models produced a survival benefit beyond 65 days.
 
In July 2012, we submitted an investigational new drug application (“IND”), to the FDA for Supinoxin. We initiated a Phase I clinical trial in August 2013 to study Supinoxin’s safety and efficacy in patients with solid tumors.  Patients in nine dose groups (25mg, 50mg, 100mg, 150mg, 225mg, 300mg, 425mg, 575mg, and 775mg) have been enrolled and the MTD of Supinoxin has not yet been reached.  Given the robust preliminary safety profile observed in the Phase Ib clinical trial to date, it is difficult to predict when we will achieve the MTD and complete the clinical trial.  We intend to present preliminary clinical findings from the ongoing Phase Ib clinical study in the third quarter of 2015.  Supinoxin continues to preliminarily demonstrate safety and tolerability, requiring higher dose levels than expected to achieve the MTD.  Based on the progress of the Supinoxin clinical development program and the level of interest expressed from a number of oncology-focused pharmaceutical companies, we are continuing our discussions with multiple companies to explore collaborative business structures in an effort to maximize the potential upside value of the program. Expenses related to Supinoxin increased for the three and six months ended June 30, 2015 compared to the same periods in 2014 primarily due to continuing enrollment and drug manufacturing costs for the clinical trial.

Pre-clinical Pipeline

RX-21101 is in a pre-clinical stage of development, and in June 2015, was selected by the National Cancer Institute's Nanotechnology Characterization Laboratory for its preclinical characterization program to facilitate the advancement of RX-21101 towards human clinical trials.  Expenses related to our pre-clinical candidates decreased for the three months ended June 30, 2015 compared to the same period in 2014, yet increased for the six months June 30, 2015 compared to the same period in 2014 primarily as a result of the timing of costs incurred for ongoing preclinical studies.

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

Cash Flows

Cash used in operating activities was $8,441,718 for the six months ended June 30, 2015.  The operating cash flows during the six months ended June 30, 2015 reflect a net loss of $7,505,871, and a net decrease of cash components of working capital and other non-cash charges totaling $935,847.  Cash used in operating activities was $5,527,773 for the six months ended June 30, 2014, which reflects a net loss of $14,406,035, including an unrealized loss on fair value of warrants of $7,995,159 and a net increase of cash components of working capital and other non-cash charges totaling $883,103.

Cash provided by investing activities was $6,871,787 for the six months ended June 30, 2015, which consisted of $7,625,000 from the redemption of marketable securities, offset by $740,825 and $12,388 for the purchases of marketable securities and equipment, respectively.  Cash provided by investing activities for the six months ended June 30, 2014 was $103,760, which consisted of a decrease in restricted cash equivalents of $117,974, offset by $14,214 for the purchase of equipment.
 
Cash provided by financing activities was $1,714,332 for the six months ended June 30, 2015 which consisted of $1,005,715 in proceeds from the sale of common stock and $708,617 in proceeds from the exercise of stock options. Cash provided by financing activities was $24,840,470 for the six months ended June 30, 2014, which consisted of net proceeds of $18,634,247 from our registered direct public offering in January 2014, $258,955 from the exercise of stock options and $5,947,268 from the exercise of warrants.

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 will first reduce research and development activities associated with our pre-clinical compounds.  To the extent necessary, we will then reduce our research and development activities related to some or all of our clinical drugs.

At Market Issuance Sales Agreement

On March 16, 2015, we entered into an at market issuance sales agreement (the “Sales Agreement”) with MLV & Co. LLC (“MLV”), pursuant to which we may issue and sell shares of our common stock having an aggregate offering price of up to $40 million from time to time, at our option, through MLV as our sales agent, subject to certain terms and conditions.  Any shares sold will be sold pursuant to our effective shelf registration statement on Form S-3 (File No. 333-196255),   as supplemented by a prospectus supplement dated March 16, 2015. We will pay MLV a commission of 3.0% of the gross proceeds of the sale of any shares sold through MLV.  As of June 30, 2015, we have sold 1,407,072 shares of common stock pursuant to the Sales Agreement for gross proceeds of $1,042,573 at a weighted average price of $0.7410 per share.  Net proceeds to us were $1,005,715 after deducting commissions and other transaction costs.  We are not obligated to make any sales under the Sales Agreement and no assurance can be given that we will sell any additional shares under the Sales Agreement, or, if we do, as to the price or amount of shares that we will sell, or the dates on which any such sales will take place.
 
Contractual Obligations

We have a variety of contractual obligations, as more fully described in our annual report on Form 10-K for the year ended December 31, 2014.  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 research and development services.  As of June 30, 2015, the total estimated cost to complete our contracts with vendors for research and development services had increased to approximately $9,670,000 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 that 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.
 
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.
 
Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

For quantitative and qualitative disclosures about market risk, refer to “Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K for the year ended December 31, 2014.  Our exposures to market risk have not changed materially since December 31, 2014.

Item 4.  Controls and Procedures.

Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) along with our Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)).  Based on that evaluation, the CEO along with the CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Our management, including the CEO and CFO, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud.  A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.  Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.  These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple error or mistake.  Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls.

Changes in Internal Control Over Financial Reporting

There have not been any changes in our internal controls over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended June 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

THIRD AMENDMENT TO LEASE

This Third Amendment to Lease (the “Third Amendment”) is made and entered into this 6 th  day of May, 2015 (the “Effective Date”), by and between SG PLAZA HOLDINGS, LLC , a Delaware limited liability company ("Landlord"), and REXAHN PHARMACEUTICALS, INC. , a Delaware corporation ("Client").

WHEREAS, The Realty Associates Fund V, L.P., as landlord (“Original Landlord”), and Client entered into a Standard Office Lease and Addendum thereto (“Addendum”), both dated June 5, 2009; and Landlord, as successor in interest to Original Landlord, and Client entered into a First Amendment to Lease dated June 7, 2013 (“First Amendment”), and a Second Amendment to Lease dated July 26, 2014 (“Second Amendment”) (collectively, the “Lease”), under which Client leases approximately seven thousand one hundred three (7,103) rentable square feet of space on the fourth (4 th ) floor of the Building (the “Premises”), comprised of Suite 455 (approximately 5,466 rentable square feet) and Suite 475 (approximately 1,637 rentable square feet), in the building located at 15245 Shady Grove Road, Rockville, Maryland 20850, and known as Shady Grove Plaza (the “Building”); and

WHEREAS, the Lease is scheduled to expire on June 30, 2019 with respect to Suite 455; and

WHEREAS, the Lease is scheduled to expire on August 31, 2015 with respect to Suite 475; and

WHEREAS, Landlord and Client wish, among other matters, to amend the Lease to extend the term of the Lease with respect to Suite 475, all on the terms hereinafter contained.

NOW THEREFORE, in consideration of the foregoing, and other good and valuable consideration, the receipt and sufficiency of which is acknowledged by the parties, the parties agree as follows:

1.              Suite 475 Extension Term/Option to Renew.

a.               The “Suite 475 Extension Term” shall commence on September 1, 2015 (the “Suite 475 Extension Term Commencement Date”) and shall expire on August 31, 2016.

b.               As of the Effective Date, Section 2.b. of the Second Amendment (regarding Client’s option to renew the Term for Suite 475) is deleted in its entirety and replaced with this Section 1.b.  Client shall have the right to extend the term of the Lease for Suite 475 for one (1) additional one (1) year lease term (the "Suite 475 Renewal Term"), provided that (i) Client has not been in default under the Lease at any time during the term of the Lease for Suite 475; (ii) Client has not previously assigned the Lease or sublet any part or all of the Premises; (iii) Client has delivered to Landlord written notice of its intention to exercise this option, not less than six (6) full months prior to the end of the Suite 475 Extension Term; (iv) all lease terms for the Suite 475 Renewal Term shall be the same as in the Lease, as amended by this Third Amendment, except that the Base Rent payable for Suite 475 during the Suite 475 Renewal Term shall be as set forth in Section 2 below; and (v) if Landlord and Client fail to agree as to all terms and sign an amendment to the Lease extending the term of the Lease for Suite 475 as provided in this Section 1.b. at least 120 days prior to the end of the Suite 475 Extension Term, all time periods for Client herein being of the essence, then, at Landlord's option, Client's option to extend the term of this Lease for Suite 475 shall lapse and Client's renewal option shall be of no force and effect.  The renewal option for Suite 475 is personal to Client and is non-transferable.  Client’s option to renew with respect to Suite 455 under Section 4 of the Addendum shall not apply with respect to Suite 475.
 
2.              Base Rent Payable for Suite 475 during the Suite 475 Extension Term and Suite 475 Renewal Term.   Effective as of Suite 475 Extension Term Commencement Date and during the Suite 475 Extension Term, Client shall pay to Landlord Base Rent for Suite 475 at the rate of Twenty-eight and 89/100 Dollars ($28.89) per rentable square foot of space, in legal tender, at Landlord’s office, the annual sum of Forty-Seven Thousand Two Hundred Ninety-two and 93/100 Dollars ($47,292.93), payable in equal monthly installments of Three Thousand Nine Hundred Forty-one and 08/100 Dollars ($3,941.08), in advance, promptly on the first day of each calendar month of the Suite 475 Extension Term, without notice or demand, the same being hereby waived, and without any setoff, deduction, or recoupment whatsoever.  In the event that Client exercises its right to renew the Lease with respect to Suite 475 as set forth in Section 1 above, the Base Rent payable for Suite 475 during the Suite 475 Renewal Term shall be Twenty-nine and 61/100 Dollars ($29.61) per rentable square foot of space, the annual sum of Forty-Eight Thousand Four Hundred Seventy-one and 57/100 Dollars ($48,471.57), payable in accordance with the provisions of the Lease in legal tender, at Landlord’s office, in equal monthly installments of Four Thousand Thirty-nine and 30/100 Dollars ($4,039.30).  The Base Rent payable under this Section 2 is for Suite 475 only and is in addition to the Base Rent payable for the Suite 455.

3.              Operating Expenses and Real Property Taxes Payable for Premises During Suite 475 Term.    During the Suite 475 Extension Term, Client shall continue to pay to Landlord Client’s Share of increased Operating Expenses and Client’s Share of increased Real Property Taxes for the Premises in accordance with the provisions of the Lease, as amended by the First and Second Amendments.

4.              Improvements to Expansion Premises.   Client agrees to accept Suite 475 in its then “as is" condition as of the Suite 475 Extension Term Commencement Date.

5.              Brokerage.   Client warrants that it has had no dealings with any broker or agent other than Studley, Inc., Client’s agent, and Lincoln Property Company, Landlord’s agent, in connection with the negotiation or execution of this Third Amendment, and Client agrees to indemnify Landlord against all costs, expenses, attorneys' fees or other liability for commissions or other compensation or charges claimed by any other broker or agent claiming the same by, through or under Client.

6.              Defined Terms.   Except as otherwise expressly provided herein, all defined terms shall have the same meanings as provided in the Lease.

7.              Headings.   Headings contained in this Third Amendment are for convenience only and are not substantive to the provisions of this Third Amendment.

8.              Lease Terms Ratified.   Except as otherwise expressly provided herein, and unless inconsistent with the terms hereof, all other terms, conditions and covenants of the Lease are hereby ratified and confirmed, and shall apply to the Premises during the Suite 475 Extension Term.  Client certifies to Landlord that the Lease is in full force and effect, that Landlord is not in default or breach of any of Landlord's obligations under the Lease, and that Client is unaware of any condition or circumstance which, but for the passage of time or delivery of notice, would constitute a default by Landlord under the Lease.
