280Bio Inc. has received FDA approval of its IND application for the KRAS inhibitor YL-17231. 280Bio will start phase I enrollment in the U.S. in the fourth quarter of this year for the treatment of advanced cancer patients with RAS mutations in their tumors.
Boehringer Ingelheim Pharma GmbH & Co. KG and Vanderbilt University have synthesized annulated 2-amino-3-cyano thiophenes and derivatives acting as KRAS GTPase and its mutant inhibitors reported to be useful for the treatment of cancer.
KRAS Q61H mutation has been found in pancreatic ductal adenocarcinoma (PDAC), colorectal cancer (CRC), and non-small-cell lung cancer (NSCLC) among other solid tumors. In healthy cells, RAS proteins switch between ON and OFF states during signal transduction, but in cancer, mutations in RAS genes or regulators install RAS proteins in ON state permanently.
Researchers at 1200 Pharma LLC have undertaken preclinical analysis of KRAS G12C inhibitors in clinical phases with the aim of finding an explanation for the differences observed in therapeutic efficacy in tumor sites other than lung, including lung-derived metastases. Results pointed to potency and pharmacokinetics as key drivers of efficacy.
Shanghai Allist Pharmaceuticals Co. Ltd. has discovered pyridopyrimidines acting as GTPase KRAS mutant inhibitors reported to be useful for the treatment of cancer.
Innovent Biologics Inc. has inked a $312 million licensing deal for the development and commercialization of Genfleet Therapeutics Inc.’s KRAS G12C inhibitor, GFH-925, in mainland China, Hong Kong, Macau and Taiwan.
