Company Description and Summary of Significant Accounting Policies | 1. Company Description and Summary of Significant Accounting Policies Nature of Business Ocuphire Pharma, Inc. (the “Company” or “Ocuphire”) is a clinical-stage ophthalmic biopharmaceutical company focused on developing and commercializing therapies for the treatment of refractive and retinal eye disorders. Ocuphire’s pipeline currently includes two small molecule product candidates targeting several of such indications. In November 2022, the Company entered into a license and collaboration agreement (the “Nyxol License Agreement”) with FamyGen Life Sciences, Inc. (acquired by Viatris, Inc. (“Viatris”) in January 2023) pursuant to which it granted Viatris an exclusive license to develop, manufacture, import, export and commercialize its product candidate phentolamine ophthalmic solution 0.75% (Nyxol® Eye Drops or “Nyxol”). Nyxol is a once-daily eye drop formulation of phentolamine mesylate designed to reduce pupil diameter and improve visual acuity. Nyxol can potentially be used across multiple indications such as treatment of pharmacologically-induced mydriasis (“RM”) (dilation of the pupil), presbyopia (age-related blurry near vision) and dim light or night vision disturbances (“DLD”) (halos, glares and starbursts). The Company’s second product candidate, APX3330, is a twice-a-day oral tablet designed to target multiple pathways relevant to retinal and choroidal (the vascular layer of the eye) diseases such as diabetic retinopathy (“DR”) and diabetic macular edema (“DME”) which, if left untreated, can result in permanent visual acuity loss and eventual blindness. The Company has also in-licensed APX2009 and APX2014, which are second-generation product candidates and analogs of APX3330. License and collaborations revenue to date was derived from a one-time non-refundable payment and reimbursement of expenses earned under the Nyxol License Agreement, and to a much lesser degree, from license agreements with BioSense Global LLC (“BioSense”) and Processa Pharmaceuticals, Inc. (“Processa”) in connection with the Rexahn RX-3117 drug compound. The Company anticipates that it will recognize revenue as it earns reimbursement for research and development services in connection with the Nyxol License Agreement and it may earn additional revenues from future potential milestone and royalty payments from the agreements with Viatris, BioSense, Processa, or from other license agreements entered into the future; however, the attainment of milestones or level of sales required to earn royalty payments is highly uncertain. Outside of the license and collaborations revenue, the Company does not expect to generate significant revenue unless or until regulatory approval is obtained and commercialization begins for Nyxol or APX3330. Management plans to continue financing the Company’s operations primarily through additional issuances of the Company’s equity and debt securities or through collaborations or partnerships with other companies. If adequate funds are not available, the Company may be required to delay, reduce the scope of, or eliminate part or all of its research and development programs. Reverse Merger with Rexahn On June 17, 2020, Ocuphire, Rexahn Pharmaceuticals, Inc. (“Rexahn”), Razor Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Rexahn (“Merger Sub”), entered into an Agreement and Plan of Merger and Reorganization, as amended on June 29, 2020 (as amended, the “Merger Agreement”), pursuant to which, among other things, and subject to the satisfaction or waiver of certain conditions set forth in the Merger Agreement, Merger Sub would merge with and into Ocuphire, with Ocuphire continuing as a wholly-owned subsidiary of Rexahn and the surviving corporation of the merger (the “Merger”). The Merger closed on November 5, 2020. Upon completion of the Merger, Rexahn changed its name to Ocuphire Pharma, Inc. and changed its ticker symbol on the Nasdaq Capital Market to “OCUP”. The Company’s headquarters is located in Farmington Hills, Michigan. Global Economic Conditions Generally, worldwide economic conditions remain uncertain, particularly due to the effects of th e COVID‑ 19 pande The COVID-19 pandemic that began in late 2019 introduced significant volatility to the global economy, disrupted supply chains and had a widespread adverse effect on the financial markets. As a result of the COVID-19 pandemic, the Company has experienced, and may continue to experience, delays and disruptions in our clinical trials, as well as interruptions in our manufacturing, supply chain, shipping and research and development operations. Testing and clinical trials, manufacturing, component supply, shipping and research and development operations may be further impacted by the continuing effects of COVID-19. Additionally, the Company’s operating results could be materially impacted by changes in the overall macroeconomic environment and other economic factors. Changes in economic conditions, supply chain constraints, logistics challenges, labor shortages, the conflict in Ukraine, and steps taken by governments and central banks, particularly in response to the COVID- pandemic as well as other stimulus and spending programs, have led to higher inflation, which has led to an increase in costs and has caused changes in fiscal and monetary policy, including increased interest rates. Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting standards generally accepted in the United States of America (“GAAP”). On December 31, 2021, the Company merged its wholly owned subsidiary, OcuSub Inc, with and into the Company, with the Company remaining as the surviving entity. The merger of the Company’s wholly owned subsidiary did not have a financial impact to the periods presented. Upon close of this merger, the Company did not have any remaining entities that required consolidation for financial statement reporting purposes. Liquidity The accompanying consolidated financial statements have been prepared on the basis that the Company will continue as a going concern. From its inception, the Company has devoted substantially all of its efforts to drug discovery and development and conducting clinical trials. The Company entered into the Nyxol License Agreement, and the one-time In the future, the Company may need to raise additional funds until it is able to generate sufficient revenues to fund its development activities. The Company’s future operating activities, coupled with its plans to raise capital or issue debt financing, may provide additional liquidity in the future, however these actions are not solely within the control of the Company and the Company is unable to predict the ultimate outcome of these actions to generate the liquidity ultimately required. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Segment Information Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The Company’s Chief Executive Officer views the Company’s operations and manages its business in one operating segment, which is the business of development and commercialization of products related to vision performance and health. Accordingly, the Company has a single reporting segment. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of 90 days or less at the time of deposit to be cash equivalents. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. As of December 31, 2022, the Company’s cash was held by two large financial institutions in the United States. Amounts on deposit may at times exceed federally insured limits. As of December 31, 2022, the Company had deposits that exceeded federally insured amounts by approximately $42.1 million. Short-term Investments The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase and are recorded on a settlement date basis. The Company’s investments are comprised of equity securities, which in accordance with the fair value hierarchy described below are recorded at fair value using Level l inputs on the balance sheets. Subsequent changes in fair values are recorded in other expense, net on the consolidated statements of comprehensive income (loss). The Company classifies investments available to fund current operations as current assets on its balance sheets. The Company did not recognize any impairments on its investments to date through December 31, 2022. Revenue Recognition The Company follows the provisions of Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers . The guidance provides a five-step model to determine how revenue is recognized. The Company has entered into license agreements which have revenue recognition implications (See Note 10 – License and Collaboration Agreements). In determining the appropriate amount of revenue to be recognized, the Company performs the following steps: (i) identification of the contracts with a customer; (ii) determination of the performance obligations in the contract; (iii) measurement of the transaction price, including potential constraints on variable consideration; (iv) allocation of the transaction price to the performance obligations based on estimated stand-alone selling prices; and (v) recognition of revenue when (or as) the Company satisfies a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC 606. Performance obligations may include license rights, development and other services. Significant management judgment is required to determine the level of effort required under an arrangement and the period over which the Company expects to complete its performance obligations under the arrangement. If the Company cannot reasonably estimate when its performance obligations are either completed or become inconsequential, then revenue recognition is deferred until the Company can reasonably make such estimates. Revenue is then recognized over the remaining estimated period of performance using the cumulative catch-up method. As part of the accounting for these arrangements, the Company must develop assumptions that require judgment to determine the stand-alone selling price of each performance obligation identified in the contract. The Company uses key assumptions to determine the stand-alone selling price, which may include forecasted revenues, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success. The Company allocates the total transaction price to each performance obligation based on the relative standalone selling prices of the promised goods or service underlying each performance obligation. Licenses of intellectual property and research and development services: Milestone payments: Royalties: Contract Asset The Company recognizes a contract asset when goods or services are transferred to the customer before the customer pays or before payment is due, excluding any amounts presented as an accounts receivable. The Company recorded a contract asset in connection with a license and collaboration agreement in the amount of $3.6 million as of December 31, 2022. See Note 10 - License and Collaboration Agreements. Accounts Receivable and Allowances for Doubtful Accounts The Company records a provision for doubtful accounts, when appropriate, based on historical experience and a detailed assessment of the collectability of its accounts receivable. In estimating the allowance for doubtful accounts, the Company considers, among other factors, the aging of the accounts receivable, its historical write-offs, the credit worthiness of each customer, and general economic conditions. Account balances are charged off against the allowance when the Company believes that it is probable that the receivable will not be recovered. Actual write-offs may be in excess of the Company’s estimated allowance. The Company has not incurred any bad debt expense during the years ended December 31, 2022 or 2021 and no allowance for doubtful accounts has been recorded during the periods presented. General and Administrative Expenses General and administrative expenses (“G&A”) consist primarily of personnel-related costs, including salaries and stock-based compensation costs, for personnel in functions not directly associated with research and development activities. Other significant costs include legal fees relating to intellectual property and corporate matters, professional fees for accounting and tax services, settlement costs with third parties and other services provided by business consultants. Research and Development Research and development expenses (“R&D”) consist of costs incurred in performing research and development activities, including compensation for research and development employees and consultants, costs associated with preclinical studies and clinical trials, regulatory activities, manufacturing activities to support clinical activities, license fees, fees paid to external service providers that conduct certain research and development, and an allocation of R&D related overhead expenses. R&D costs include costs that are reimbursed under the Nyxol License Agreement. Other Expense, net Other expense, net reflected in this line item includes payments made by the Company in connection with the Contingent Value Rights Agreement discussed further below with former Rexahn shareholders. In addition, other expense, net includes interest earned from cash and cash equivalent investments, realized and unrealized gains (losses) from equity investments and reimbursements in connection with grants and other sources when they occur. Stock-based Compensation The Company accounts for stock-based compensation in accordance with the provisions of the Financial Accounting Standards Board (“FASB”) ASC 718, Compensation — Stock Compensation Warrant Liabilities The Company issued Series A Warrants in connection with the Pre-Merger Financing (see Note 3 – Pre-Merger Financing) and assumed Rexahn warrants issued prior to the Merger. The Company accounts for these warrants as a liability while outstanding at fair value during periods when certain provisions preclude equity accounting treatment for these instruments. Additionally, issuance costs associated with the warrants classified as liabilities were expensed as incurred and reflected as interest expense in the accompanying consolidated statements of comprehensive income (loss). The change in fair value of the warrant liabilities while outstanding were recognized as a component of the fair value change in warrant liabilities line item in the consolidated statements of comprehensive income (loss). Fair Value Measurements The Company follows accounting guidance that emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Fair value is defined 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.” Fair value measurements are defined on a three-level hierarchy: • Level 1 inputs: Unadjusted quoted prices for identical assets or liabilities in active markets; • Level 2 inputs: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, whether directly or indirectly, for substantially the full term of the asset or liability; and • Level 3 inputs: Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date. As of December and the fair values of cash and cash equivalents, accounts receivable, contract asset, prepaid and other assets, accounts payable, accrued expenses and short-term loan, while outstanding, approximated their carrying values because of the short-term nature of these assets or liabilities. The fair value of the short-term investments was based on observable Level inputs in the form of quoted market prices from a major stock exchange. The fair value of the warrant liabilities, while outstanding, was based on cash flow models discounted at current implied market rates evidenced in recent arms-length transactions representing expected returns by market participants for similar instruments and were based on Level inputs. There were no transfers between fair value hierarchy levels during the years ended December 31, 2022 and 2021. The fair value of financial instruments measured on a recurring basis is as follows (in thousands): As of December 31, 2022 Description Total Level 1 Level 2 Level 3 Assets: Short-term investments $ 49 $ 49 $ — $ — Total assets at fair value $ 49 $ 49 $ — $ — As of December 31, 2021 Description Total Level 1 Level 2 Level 3 Assets: Short-term investments $ 219 $ 219 $ — $ — Total assets at fair value $ 219 $ 219 $ — $ — The following table provides a roll-forward of investments measured at fair value on a recurring basis using observable level 1 inputs for the year ended December 31, 2022 and 2021 (in thousands): 2022 2021 Short-term investments Balance as of beginning of period $ 219 $ — Receipt of investments related to license agreement — 289 Unrealized loss (170 ) (70 ) Balance as of end of period $ 49 $ 219 The following table provides a roll-forward of the warrant liabilities measured at fair value on a recurring basis using unobservable level 3 inputs for the year ended December 31, 2021 (in thousands): 2021 Warrant liabilities Balance as of beginning of period $ 27,964 Change in fair value of warrant liabilities 33,829 Reclassification of warrants from liability to equity (61,793 ) Balance as of end of period $ — The fair value of the warrant liabilities associated with the Rexahn warrants was de minimis during the years ended December 31, 2022 and 2021. See Note 2 - Merger. There were no financial instruments measured on a non-recurring basis for any of the periods presented. Income Taxes The Company utilizes the liability method of accounting for income taxes as required by ASC 740, Income Taxes Property and Equipment, net Property and equipment, net is recorded at cost and reduced by accumulated depreciation. Depreciation expense is recognized over the estimated useful lives of the assets using the straight-line method. Equipment and furniture are depreciated over a five-year estimated useful life. Tangible assets acquired for research and development activities which have alternative use are capitalized and depreciated over the useful life of the acquired asset. Estimated useful lives are periodically reviewed, and when appropriate, changes are made prospectively. When certain events or changes in operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed on the recoverability of the carrying amounts. Maintenance and repairs are charged directly to expense as incurred. Recent Accounting Pronouncements In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, “ Financial Instruments – Credit Losses” In August 2020, FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity which, among other things, provides guidance on how to account for contracts on an entity’s own equity. This ASU eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, this ASU modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. The amendments in this ASU are effective for public business entities that meet the definition of a Securities and Exchange Commission (“SEC”) filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The Company does not expect that the adoption of this ASU on January 1, 2023 on its consolidated financial statements will be material . In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) - Disclosures by Business Entities about Government Assistance, to increase the transparency of government assistance including the disclosure of the types of assistance, an entity’s accounting for the assistance, and the effect of the assistance on an entity’s financial statements. The amendments in this ASU are effective for all entities within their scope for financial statements issued for annual periods beginning after December 15, 2021. The Company adopted this guidance on January 1, 2022 and it did not have a material impact to the consolidated financial statements. |
