IDEAYA Biosciences, Inc., a precision medicine oncology company, discovers and develops targeted therapeutics for patient populations selected using molecular diagnostics in the United States. The company’s products in development include IDE196, a protein kinase C inhibitor that is in Phase 2/3 clinical trials for genetically defined cancers having GNAQ or GNA11 gene mutations; IDE397, a methionine adenosyltransferase 2a inhibitor that is in Phase 2 clinical trials for patients with solid tumors having methylthioadenosine phosphorylase gene deletions, such as non-small cell lung (SCLC) and MTAP-deletion urothelial cancer; IDE849, a DLL3 antibody drug conjugate inhibitor that is in Phase 1 clinical trial for the treatment of SCLC and neuroendocrine tumors; IDE275, a Werner Helicase inhibitor that is in Phase 1 clinical trial for patients having tumors with high microsatellite instability; IDE161, a poly ADP-ribose glycohydrolase inhibitor that is in Phase 1/2 clinical trial to treat tumors with homologous recombination deficiency (HRD), and other genetic or molecular signatures; IDE705 (GSK101), a Poly Theta Helicase inhibitor that is in Phase 1 clinical trial for the treatment of tumors with BRCA or other mutations associated with HRD. It also develops preclinical programs, including IDE892, a MTA-cooperative PRMT5 inhibitor; IDE034, a B7H3/PTK7 topo-I-payload bispecific BsADC; and IDE251, a KAT6/7 inhibitor. In addition, the company offers preclinical research programs focused on pharmacological inhibition; DECIPHER dual CRISPR library for synthetic lethality target and biomarker discovery; and INQUIRE chemical library and HARMONY machine-learning engines to enhance its drug discovery platform.
