Accounting Policies [Abstract] |
The Company and Summary of Significant Accounting Policies | (1) The Company and Summary of Significant Accounting Policies Description of Business ARCA biopharma, Inc. (the Company or ARCA), a Delaware corporation, is headquartered in Westminster, Colorado. The Company is a clinical-stage biopharmaceutical company applying a precision medicine approach to the development and commercialization of genetically targeted therapies for cardiovascular diseases. The Company’s lead product candidates are rNAPc2 (AB201) as a potential treatment for diseases caused by ribonucleic acid, or RNA, viruses, initially focusing on COVID-19, the disease caused by SARS-CoV-2 virus, and Gencaro™ (bucindolol hydrochloride) for the treatment of atrial fibrillation (AF) in patients with chronic heart failure (HF). rNAPc2 is a protein therapeutic in clinical development as a potential treatment for patients hospitalized with COVID-19. Based on its unique mechanism of action, development history and the clinical evidence from the SARS‑CoV-2 pandemic, the Company believes rNAPc2 has potential to be a beneficial therapy for patients with this serious viral disease. The Company initiated the Phase 2b clinical trial of rNAPc2 as a potential treatment for patients hospitalized with COVID-19 in the fourth quarter of 2020. The Company continues to evaluate the feasibility and potential timing for initiating PRECISION-AF relative to the COVID-19 pandemic and prioritizing the development of rNAPc2. The Company’s other product candidate, AB171, is a thiol-substituted isosorbide mononitrate, which ARCA plans to develop as a genetically-targeted treatment for HF and peripheral arterial disease. In March 2020, the World Health Organization declared the outbreak of COVID-19, a novel strain of Coronavirus, a global pandemic. This outbreak is causing major disruptions to businesses and markets worldwide as the virus spreads. The Company does not expect a material financial effect as a result of the pandemic. However, if the pandemic continues to be a severe worldwide crisis, it could have a material adverse effect on the Company’s business, results of operations, financial condition and cash flows. Liquidity and Going Concern The Company devotes substantially all of its efforts towards obtaining regulatory approval and raising capital necessary to fund its operations and it is subject to a number of risks associated with clinical research and development, including dependence on key individuals, the development of and regulatory approval of commercially viable products, the need to raise adequate additional financing necessary to fund the development and commercialization of its products, and competition from larger companies. The Company has not generated revenue to date and has incurred substantial losses and negative cash flows from operations since its inception. The Company has historically funded its operations through issuances of common and preferred stock. The Company believes that its current cash and cash equivalents as of March 31, 2021 will be sufficient to fund its operations through the end of fiscal year 2022. Conducting a Phase 3 rNAPc2 clinical trial or the Phase 3 PRECISION-AF trial would likely require additional financing. However, changing circumstances may cause us to consume capital significantly faster or slower than currently anticipated. The Company has based these estimates on assumptions that may prove to be wrong, and the Company could exhaust its available financial resources sooner than the Company currently anticipates. Therefore, the Company may have to raise additional capital for clinical trials of rNAPc2 and will have to raise additional capital for clinical trials of Gencaro. The Company may not be able to raise sufficient capital on acceptable terms, or at all, to continue development of rNAPc2 or Gencaro or to otherwise continue operations and may not be able to execute any strategic transaction. The Company’s liquidity, and its ability to raise additional capital or complete any strategic transaction, depends on a number of factors, including, but not limited to, the following:
| • | the costs and timing for the potential additional clinical trials in order to gain possible regulatory approval for rNAPc2, Gencaro or any other product candidate;
| • | the market price of the Company’s stock and the availability and cost of additional equity capital from existing and potential new investors;
| • | the Company’s ability to retain the listing of its common stock on the Nasdaq Capital Market;
| • | general economic and industry conditions affecting the availability and cost of capital, including as a result of the COVID-19 pandemic;
| • | the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights; and
| • | the terms and conditions of the Company’s existing collaborative and licensing agreements.
The sale of additional equity or convertible debt securities would likely result in substantial additional dilution to the Company’s stockholders. If the Company raises additional funds through the incurrence of indebtedness, the obligations related to such indebtedness would be senior to rights of holders of the Company’s capital stock and could contain covenants that would restrict the Company’s operations. The Company also cannot predict what consideration might be available, if any, to the Company or its stockholders, in connection with any strategic transaction. Should strategic alternatives or additional capital not be available to the Company, or not be available on acceptable terms, the Company may be unable to realize value from its assets and discharge its liabilities in the normal course of business which may, among other alternatives, cause the Company to further delay, substantially reduce or discontinue operational activities to conserve its cash resources. Basis of Presentation The accompanying unaudited financial statements of the Company were prepared in accordance with generally accepted accounting principles for interim financial information and instructions to Form 10-Q and pursuant to Regulation S-X. Accordingly, these financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (GAAP) for complete financial statements. In the opinion of management, these financial statements include all normal and recurring adjustments considered necessary for a fair presentation of these interim financial statements. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of results expected for the full year ending December 31, 2021. The Company has generated no revenue to date and its activities have consisted of seeking regulatory approval, research and development, exploring strategic alternatives for further developing and commercializing rNAPc2 and Gencaro, and raising capital. These unaudited financial statements should be read in conjunction with the audited financial statements and footnotes thereto for the year ended December 31, 2020 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission. Amounts presented are rounded to the nearest thousand, where indicated, except per share data and par values. Concentrations of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company has no off-balance-sheet concentrations of credit risk, such as foreign exchange contracts, option contracts, or foreign currency hedging arrangements. The Company maintains cash and cash equivalent balances in the form of bank demand deposits and money market fund accounts with financial institutions that management believes are creditworthy. Such balances may at times exceed the insured amount. Comprehensive Loss Comprehensive loss is defined as the change in equity during a period from transactions and other events and/or circumstances from non-owner sources. If the Company had comprehensive gains (losses), they would be reflected in the statement of operations and comprehensive loss and as a separate component in the statement of stockholders’ equity. There were no elements of comprehensive loss during the three months ended March 31, 2021 and 2020. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in right-of-use (ROU) asset – operating and lease obligations are included in accrued expenses and other liabilities and operating lease liability on the Company’s March 31, 2021 and December 31, 2020 balance sheets. ROU lease assets represent the Company’s right to use an underlying asset for the lease term and lease obligations represent the Company’s obligation to make lease payments arising from the lease. Operating ROU lease assets are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company’s lease does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Accrued Outsourcing Expenses As part of the process of preparing its financial statements, the Company is required to estimate accrued outsourcing expenses. This process involves identifying services that third parties have performed on the Company’s behalf and estimating the level of service performed and the associated cost incurred for these services as of the balance sheet date. Examples of estimated accrued outsourcing expenses include contract service fees, such as fees payable to contract manufacturers in connection with the production of materials related to the Company’s drug product, and service fees and pass through costs from clinical research organizations. The Company develops estimates of liabilities using its judgment based upon the facts and circumstances known at the time. Recent Accounting Pronouncements The Company reviewed recently issued accounting pronouncements and concluded that they were either not applicable or not expected to have a significant impact to the financial statements.
