Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Continued Utilization of the At-The-Market Facility The Company continued utilization of its At-The-Market facility from April 1 through April 30, 2022 and sold 318,156 shares which generated net proceeds of approximately $505. Lincoln Park Purchase Agreement On April 12, 2022, the Company entered into a purchase agreement ("Lincoln Park Purchase Agreement") with Lincoln Park Capital Fund, LLC ("Lincoln Park"), which provides that, upon the terms and subject to the conditions and limitations set forth in the Lincoln Park Purchase Agreement, the Company has the right, but not the obligation, to sell to Lincoln Park up to $40,000 worth of shares of its common stock from time to time over the 36-month term of the Lincoln Park Purchase Agreement. Concurrently with entering into the Lincoln Park Purchase Agreement, the Company also entered into a registration rights agreement with Lincoln Park, pursuant to which the Company agreed to register the sale of the shares of its common stock that have been and may be issued to Lincoln Park under the Lincoln Park Purchase Agreement pursuant to its existing shelf registration statement on Form S-3 or a new registration statement. Lincoln Park has covenanted under the Lincoln Park Purchase Agreement not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of the Company's common stock. Since inception through April 30, 2022, the Company issued 403,982 shares which generated sale proceeds of approximately $707 in connection with the Lincoln Park Purchase Agreement. Haisco Receivable The Company entered into a License, Development and Supply Agreement with Haisco Pharmaceutical Group Co., Ltd., a Chinese limited company listed on the Shenzhen Stock Exchange ("Haisco") effective as of March 3, 2022 ("Haisco Agreement") pursuant to which Aquestive granted Haisco an exclusive license to develop and commercialize Exservan™ (riluzole oral film) for the treatment of amyotrophic lateral sclerosis, or ALS (“Exservan) in China and Aquestive will serve as the exclusive sole manufacturer and supplier for Exservan in China. Pursuant to the Haisco License Agreement, Haisco has been appointed to serve as Aquestive’s agent for matters relating to the commercialization of Exservan in China, including obtaining approval to market and sell ("Marketing Authorization") Exservan in China. Subsequent to the execution of the Haisco Agreement in March 2022, the Chinese equivalent of the FDA (the "NMPA") raised an issue regarding the named holder of the U.S. New Drug Application (NDA) for Exservan in relation to the application for Marketing Authorization of Exservan in China. It is not clear whether the NMPA will require that Aquestive be the holder of the NDA in order to approve the Marketing Authorization for Exservan in China, or whether the NMPA will find that Aquestive's qualifications as the exclusive licensor, manufacturer and innovator of Exservan will be sufficient for the NMPA to approve Aquestive as the drug sponsor for Exservan in China and grant the Marketing Authorization for Exservan in China. Prior to entering into the Haisco Agreement, the Company had assigned the NDA for Exservan to another third-party in connection with a license agreement in the U.S. for Exservan and is not currently the named holder of the NDA. The Company is collaborating with Haisco to resolve this issue with the NMPA. As a result of this issue, the Company has not received the $7,000 upfront payment due from Haisco under the Haisco Agreement and expects to agree with Haisco to extend the period of time under which Haisco is obligated to make said upfront payment consistent with the decision of the NMPA on this issue, or as otherwise agreed to by the Company and Haisco.
