Organization Consolidation And Presentation Of Financial Statements [Abstract]
Operations	1.Operations The accompanying condensed consolidated financial statements of EyePoint Pharmaceuticals, Inc., a Delaware corporation (together with its subsidiaries, the “Company”), as of September 30, 2021 and for the three and nine months ended September 30, 2021 and 2020 are unaudited. Certain information in the footnote disclosures of these financial statements has been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). These financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. In the opinion of management, these statements have been prepared on the same basis as the audited consolidated financial statements as of and for the year ended December 31, 2020, and include all adjustments, consisting only of normal recurring adjustments, that are necessary for the fair presentation of the Company’s financial position, results of operations, comprehensive loss and cash flows for the periods indicated. The preparation of financial statements in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make assumptions and estimates that affect, among other things, (i) reported amounts of assets and liabilities; (ii) disclosure of contingent assets and liabilities at the date of the consolidated financial statements; and (iii) reported amounts of revenues and expenses during the reporting period. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the entire fiscal year or any future period. The Company is a pharmaceutical company committed to developing and commercializing innovative therapeutics to help improve the lives of patients with serious eye disorders. The Company’s pipeline leverages its proprietary Durasert^® technology for extended intraocular drug delivery including EYP-1901, a potential twice-yearly sustained delivery intravitreal anti-VEGF treatment initially targeting wet age-related macular degeneration (“wet AMD”), the leading cause of vision loss among people 50 years of age and older in the United States. The Company’s product candidate pipeline also includes YUTIQ^® 50, a potential six-month treatment for non-infectious uveitis affecting the posterior segment of the eye, one of the leading causes of blindness. The Company also has two commercial products: YUTIQ^®, a once every three-year treatment for chronic non-infectious uveitis affecting the posterior segment of the eye, and DEXYCU^®, a single dose treatment for postoperative inflammation following ocular surgery. Local drug delivery for treating ocular diseases is a significant challenge due to the effectiveness of the blood-eye barrier. This barrier makes it difficult for systemically-administered drugs to reach the eye in sufficient quantities to have a beneficial effect without causing unacceptable adverse side effects to other organs. The Company’s validated Durasert technology, which has already been included in four products approved for marketing by the U.S. Food and Drug Administration (“FDA”), is designed to provide consistent, sustained delivery of small molecule drugs over a period of months to years through a single intravitreal injection. The Company’s lead product candidate, EYP-1901, combines a bioerodible formulation of its proprietary Durasert sustained-release technology with vorolanib, a tyrosine kinase inhibitor (“TKI”). Current approved treatments for wet AMD require monthly or bi-monthly eye injections in a physician’s office, which can cause inconvenience and discomfort and often lead to reduced compliance and poor outcomes. The Company is currently evaluating EYP-1901 in a Phase 1 clinical trial (“DAVIO”) as a potential twice-yearly sustained delivery intravitreal treatment for wet AMD. On September 17, 2021, the Company announced that a late-breaking abstract highlighting topline data for the DAVIO trial was selected for presentation at the American Academy of Ophthalmology (“AAO”) 2021 Annual Meeting scheduled on November 13, 2021. On October 12, 2021, the Company reported positive 3-month safety data results for all dose levels from the ongoing DAVIO trial of EYP-1901 for wet AMD at the American Society of Retina Specialists (“ASRS”) Annual Meeting. The Company is also developing YUTIQ 50 as a potential six-month intravitreal treatment for non-infectious uveitis affecting the posterior segment of the eye. The Company anticipates the initiation of a Phase 3 clinical trial for YUTIQ 50 in the fourth quarter of 2021 and expects to file for a supplemental new drug application (“sNDA”) approval with the FDA upon successful completion of the trial. The Company also has two commercial products, YUTIQ^® and DEXYCU^®, that are being sold directly in the U.S. YUTIQ^® (fluocinolone acetonide intravitreal implant) 0.18 mg for intravitreal injection, is a non-erodible intravitreal implant containing fluocinolone acetonide (“FA”) lasting for up to 36 months and is indicated for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye. This disease affects between 60,000 to 100,000 people each year in the U.S. causes approximately 30,000 new cases of blindness every year and is the third leading cause of blindness. YUTIQ utilizes the Company’s proprietary Durasert^® sustained-release drug delivery technology platform. DEXYCU^® (dexamethasone intraocular suspension) 9%, for intraocular administration, is indicated for the treatment of post-operative ocular inflammation, with the Company’s primary focus on its use immediately following cataract surgery as a single dose treatment. DEXYCU utilizes the Company’s proprietary Verisome^® drug-delivery technology. The Company is also seeking to enhance its long-term growth potential by expanding EYP-1901 beyond wet AMD into diabetic retinopathy (“DR”) and retinal vein occlusion (“RVO”), both large and growing ocular disease areas. The Company also expects to potentially identify and advance additional product pipeline candidates through clinical and regulatory development. This may be accomplished through internal discovery efforts, potential research collaborations and/or in-licensing arrangements with partner molecules and potential acquisitions of additional ophthalmic products, product candidates or technologies that complement the Company’s current product portfolio. Effects of the COVID-19 Coronavirus Pandemic The ongoing COVID-19 coronavirus pandemic (the “Pandemic”) has had a material and adverse impact on the Company’s business, including as a result of measures that the Company, other businesses, and governments have taken and will possibly continue to take. This includes a significant impact on cash flows from expected revenues due to the closure of ambulatory surgery centers for DEXYCU and a significant reduction in physician office visits impacting YUTIQ in 2020. The ongoing Pandemic continued to have an adverse impact on the Company’s revenues, financial condition and cash flows through the third quarter of 2021. Additionally, the emergence of new variants of the coronavirus has caused and may continue to cause intermittent or prolonged periods of reduced patient services at the Company’s customers’ facilities, which may negatively affect customer demand. The progression of the Pandemic and its effects on the Company’s business and operations are uncertain at this time. Depending on the future developments that are uncertain and difficult to predict, including new information that may emerge concerning the Pandemic, the Company’s revenues, financial condition and cash flows may be adversely affected in the future as well. The Company is continuously monitoring the Pandemic and its potential effect on the Company’s financial position, results of operations and cash flows. This uncertainty could have an impact in future periods on certain estimates used in the preparation of the Company’s periodic financial results, including reserves for variable consideration related to product sales, realizability of certain receivables, assessment for excess or obsolete inventory, and impairment of long-lived assets. Uncertainty around the extent and duration of the Pandemic, and any future related financial impact cannot be reasonably estimated at this time. Liquidity The Company had cash and cash equivalents of $119.7 million at September 30, 2021. The Company has a history of operating losses and has not had significant recurring cash inflows from revenue. The Company’s operations have been financed primarily from sales of its equity securities, issuance of debt and a combination of license fees, milestone payments, royalty income and other fees received from its collaboration partners. In the first quarter of 2019, the Company commenced the U.S. launch of its first two commercial products, YUTIQ and DEXYCU. However, the Company has not received sufficient revenues from its product sales to fund operations and the Company does not expect revenues from its product sales to generate sufficient funding to sustain its operations in the near-term. The Company expects to continue fulfilling its funding needs through cash inflows from revenue of YUTIQ and DEXYCU product sales, licensing and research collaboration transactions, additional equity capital raises and other arrangements. The Company believes that its cash and cash equivalents of $119.7 million at September 30, 2021, coupled with expected cash inflows from its product sales will enable the Company to fund its current and planned operations for at least the next twelve months from the date these consolidated financial statements were issued. Actual cash requirements could differ from management’s projections due to many factors, including the continued effect of the Pandemic on the Company’s business and the medical community, the timing and results of the Company’s clinical trials for EYP-1901 and YUTIQ 50, additional investments in research and development programs, the success of ongoing commercialization efforts for YUTIQ and DEXYCU, the actual costs of these ongoing commercialization efforts, competing technological and market developments and the costs of any strategic acquisitions and/or development of complementary business opportunities. Recently Adopted and Recently Issued Accounting Pronouncements New accounting pronouncements are issued periodically by the Financial Accounting Standards Board (“FASB”) and are adopted by the Company as of the specified effective dates. Unless otherwise disclosed below, the Company believes that recently issued and adopted pronouncements will not have a material impact on the Company’s financial position, results of operations and cash flows or do not apply to the Company’s operations. In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt— Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2021-04”): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. The amendments are designed to clarify an issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options that remain equity-classified after modification or exchange. The ASU provides guidance on how an issuer would measure and recognize the effects of these transactions. The standard provides a principles-based framework to determine whether an issuer should recognize the modification or exchange as an adjustment to equity or an expense. ASU 2021-04 is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. ASU 2021-04 will be effective for the Company in the first quarter of its fiscal year ending December 31, 2022. The Company is currently evaluating the impact the adoption of this update will have on its consolidated financial statements.
