News Release - November 1, 2021
Theseus Pharmaceuticals Announces FDA Clearance of Investigational New Drug Application for THE-630, a Pan-Variant KIT Inhibitor in Development for the Treatment of Gastrointestinal Stromal Tumors (GIST)CAMBRIDGE, Mass., Nov. 1, 2021 -- (Healthcare Sales & Marketing Network) --Theseus Pharmaceuticals, Inc. ("Theseus"), a biopharmaceutical company focused on improving the lives of cancer patients through the discovery, development and commercialization of transformative targeted therapies, today announced U.S. Food and Drug Administration (FDA) clearance of an investigational new drug (IND) application to evaluate THE-630, the company's lead development candidate, in patients with gastrointestinal stromal tumors (GIST). THE-630 is a pan-variant inhibitor of the receptor tyrosine kinase KIT designed for patients with advanced GIST whose cancer has developed resistance to earlier lines of therapy.
THE-630 exhibits potent in vitro activity against all known classes of KIT activating and resistance mutations in GIST. In preclinical studies, THE-630 achieved predicted pan-variant KIT inhibitory blood concentrations at tolerable doses and induced significant anti-tumor activity. Theseus plans to initiate a Phase 1/2 dose escalation and expansion clinical trial of THE-630 in patients with previously treated advanced GIST between late fourth quarter 2021 and mid-first quarter 2022.
