Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Shattuck Labs, Inc. (the “Company”) was incorporated in 2016 in the State of Delaware and is a clinical-stage biopharmaceutical company developing dual-sided fusion proteins, including its Agonist Redirected Checkpoint (“ARC®”) and gamma delta T cell engager (“GADLEN™”) platforms, as novel classes of biologic medicines capable of multifunctional activity with potential applications in oncology and inflammatory diseases. Using its proprietary technology, the Company is building a pipeline of therapeutics, initially focused on the treatment of solid tumors and hematologic malignancies. The Company has two clinical-stage product candidates, SL-172154 and SL-279252, and has several compounds in preclinical development. Liquidity The Company has incurred losses and negative cash flows from operations since inception and has an accumulated deficit of $193.6 million as of September 30, 2022. The Company anticipates incurring additional losses and negative cash flows from operations until such time, if ever, that it can generate significant sales of its product candidates currently in development, and is highly dependent on its ability to find additional sources of funding in the form of licensing of its technology, collaboration agreements and/or public and private debt and equity financings. Adequate additional funding may not be available to the Company on acceptable terms, or at all. The failure to raise funds as and when needed could have a negative impact on the Company’s financial condition and ability to pursue its clinical operations, research and development and commercialization of its product candidates. Management believes that the Company’s cash and cash equivalents and investments of $185.1 million as of September 30, 2022 are sufficient to fund projected operations of the Company for at least the next twelve months. COVID-19 Pandemic The COVID-19 pandemic has had, and may continue to have, a broad adverse impact on the economies and financial markets of many countries, including the geographical areas in which the Company operates and conducts its business and in which the Company’s partners operate and conduct their business. The Company and its third-party vendors and consultants have experienced disruptions to their businesses as a result of the COVID-19 pandemic. Specifically, the outbreak has caused disruptions in its ability to manufacture clinical trial materials, including the acquisition of raw materials needed for such manufacturing, enrollment and treatment of patients in clinical trials, and slowdowns and shutdowns of the laboratories and other service providers that are being relied upon in the development of the Company’s product candidates. The extent to which the COVID-19 pandemic or any other health epidemic may impact the Company’s results will depend on future developments, which are uncertain and cannot be predicted. Accordingly, the COVID-19 pandemic could have a material and adverse effect on the Company’s business, results of operations and financial condition. Global Economic Considerations In addition, the global macroeconomic environment is uncertain, and could be negatively affected by, among other things, COVID-19 or other pandemics or epidemics, increased U.S. trade tariffs and trade disputes with other countries, instability in the global capital and credit markets, supply chain weaknesses, and instability in the geopolitical environment, including as a result of the Russian invasion of Ukraine and other political tensions. Such challenges have caused, and may continue to cause, recession fears, rising interest rates, foreign exchange volatility and inflationary pressures. At this time, we are unable to quantify the potential effects of this economic instability on our future operations.
