IDEAYA Biosciences, Inc. is a precision medicine oncology company that develops targeted therapeutics for patient populations selected using molecular diagnostics in the United States. Its lead product, Darovasertib, is an oral, potent, and selective protein kinase C (PKC) inhibitor for the treatment of uveal melanoma and ocular cancer, and is being evaluated in multiple clinical trials as monotherapy and in combination with crizotinib for metastatic, neoadjuvant, and adjuvant settings. The company also offers IDE849, a DLL3 antibody-drug conjugate inhibitor for SCLC and neuroendocrine carcinomas; IDE034, a B7H3/PTK7 topo-I-payload bispecific BsADC; IDE161, a poly ADP-ribose glycohydrolase inhibitor; IDE705 (GSK101), a Poly Theta Helicase inhibitor in Phase 1 for tumors with BRCA or other mutations associated with HRD; IDE397, a MAT2A inhibitor for MTAP-deleted tumors; IDE892, a PRMT5 inhibitor; IDE574, which selectively inhibits KAT6/7 and is in a Phase 1 dose escalation trial for breast, lung, prostate, and colorectal cancers; and IDE275, an oral small molecule inhibitor of the helicase domain of the Werner protein (WRN) in a Phase 1 clinical trial. In addition, the company has 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. It has strategic alliances with GlaxoSmithKline, Pfizer Inc., Gilead Sciences, Inc., Novartis, Biocytogen, Cancer Research UK, the University of Manchester, Jiangsu Hengrui Pharmaceuticals Co., Ltd., and Les Laboratoires Servier. It also has a clinical collaboration agreement with AstraZeneca plc to evaluate IDE849, an antibody-drug conjugate, and a clinical collaboration with Roche to evaluate IDE892, IDEAYA's potential best-in-class Phase 1 MTA-cooperative PRMT5 inhibitor, in combination with RG6505, Roche's Phase 1 pan-R.
