Business And Liquidity [Abstract]
Business and Liquidity	(1) Business and Liquidity MiNK Therapeutics, Inc. (“MiNK” or the “Company”) is a clinical stage biopharmaceutical company pioneering the discovery, development and commercialization of allogeneic, off-the-shelf, invariant natural killer T (“iNKT”) cell therapies to treat cancer and other immune-mediated diseases. iNKT cells are a distinct T cell population that combine durable memory responses with the rapid cytolytic features of natural killer cells. iNKT cells offer distinct therapeutic advantages as a platform for allogeneic therapy in that the cells naturally home to tissues, aid clearance of tumors and infected cells and suppress graft-versus-host-disease. MiNK’s proprietary platform is designed to facilitate scalable and reproducible manufacturing for off-the-shelf delivery. As such, the Company believes that its approach represents a highly versatile application for therapeutic development in cancer and immune diseases. MiNK is leveraging its platform and manufacturing capabilities to develop a wholly owned or exclusively licensed pipeline of both native and engineered iNKT cells. Since inception, in 2017, until the completion of the Company’s initial public offering (“IPO”), the Company financed its operations primarily through funding from Agenus Inc. (“Agenus”), its parent company. The Company has incurred losses since inception and, as of March 31, 2022, had an accumulated deficit of $90.7 million. MiNK expects to continue incurring operating losses and negative cash flows for the foreseeable future. Based on the Company’s current plans and projections, MiNK believes its cash and cash equivalents balance as of March 31, 2022 of $34.7 million will be sufficient to satisfy its liquidity requirements for more than one year from when these financial statements were issued. Management continually addresses the Company’s liquidity position and adjusts spending as needed in order to preserve liquidity. The Company’s future liquidity needs will be determined primarily by the success of its operations with respect to the progression of the Company’s product candidates and key development and regulatory events in the future. Potential sources of additional funding for the Company include: (1) pursuing collaboration, out-licensing and/or partnering opportunities for the Company’s portfolio programs and product candidates with one or more third parties, (2) securing debt financing and/or (3) selling equity securities. MiNK’s product candidates are in various stages of development and significant additional expenditures will be required if the Company starts new trials, encounters delays in its programs, applies for regulatory approvals, continues development of its technologies, expands its operations, and/or brings its product candidates to market. The eventual total cost of each clinical trial is dependent on a number of factors such as trial design, length of the trial, number of clinical sites, and number of patients. The process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive, and uncertain. Because all of the Company’s programs are at an early stage of clinical development, the Company is unable to reliably estimate the cost of completing its research and development programs or the timing for bringing such programs to various markets or substantial partnering or out-licensing arrangements, and, therefore, when, if ever, material cash inflows are likely to commence.
