Organization and Nature of Business |
Organization and Nature of Business | 1. Organization and Nature of Business ​ Overview ​ Aclaris Therapeutics, Inc. was incorporated under the laws of the State of Delaware in 2012. Aclaris Therapeutics, Inc. and its wholly owned subsidiaries are referred to collectively as the “Company.” ​ The Company is a clinical-stage biopharmaceutical company focused on developing novel small and large molecule product candidates for immuno-inflammatory diseases. The Company’s proprietary KINect drug discovery platform combined with its preclinical development capabilities allows the Company to identify and advance potential product candidates that it may develop independently or in collaboration with third parties. In addition to identifying and developing its novel product candidates, the Company is pursuing strategic alternatives, including identifying and consummating transactions with third-party partners, to further develop, obtain marketing approval for and/or commercialize its novel product candidates. The Company also provides contract research services to third parties enabled by its early-stage research and development expertise. ​ Liquidity ​ The Company’s condensed consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities in the ordinary course of business. As of September 30, 2025, the Company had cash, cash equivalents and marketable securities of $167.2 million and an accumulated deficit of $948.0 million. Since inception, the Company has incurred net losses and negative cash flows from its operations. There can be no assurance that profitable operations will ever be achieved, and, if achieved, will be sustained on a continuing basis. In addition, development activities, including clinical and preclinical testing of the Company’s product candidates, will require significant additional financing. The future viability of the Company is dependent on its ability to successfully develop its product candidates and to generate revenue from identifying and consummating transactions with third-party partners to further develop, obtain marketing approval for and/or commercialize its development assets or to raise additional capital to finance its operations. The Company will require additional capital to develop its product candidates and to support its discovery efforts. ​ Additional funds may not be available on a timely basis, on commercially acceptable terms, or at all, and such funds, if raised, may not be sufficient to enable the Company to continue to implement its long-term business strategy. The Company's ability to raise additional capital may be adversely impacted by potentially worsening global economic conditions caused by a variety of factors including geopolitical tensions, inflationary pressures, tariff policies, and the current shutdown of the U.S. federal government. If the Company is unable to raise sufficient additional capital or generate revenue from transactions with potential third-party partners for the development and/or commercialization of its product candidates, it may need to substantially curtail planned operations. The Company’s failure to raise capital as and when needed could have a negative impact on its financial condition and ability to pursue its business strategies. ​ In accordance with Accounting Standards Codification (“ASC”) Subtopic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, the Company evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that its condensed consolidated financial statements are issued. As of the report date, the Company does not believe that substantial doubt exists about its ability to continue as a going concern. The Company believes its existing cash, cash equivalents and marketable securities are sufficient to fund its operating and capital expenditure requirements for a period greater than 12 months from the date of issuance of these condensed consolidated financial statements.
