President, Chief Executive Officer And Co-Founder
Wellspring and its parent company, Araxes Pharma, are closely held and committed to creating breakthrough medicines for the treatment of cancer and other serious diseases. The companies were founded by Yi Liu, Ph.D., Pingda Ren, Ph.D., Kevan Shokat, Ph.D. and Troy Wilson, Ph.D., J.D., based upon pioneering research into KRAS G12C inhibitors conducted by Dr. Shokat, HHMI Investigator and Professor of Molecular and Cellular Pharmacology, and colleagues at the University of California, San Francisco. The Shokat group discovered a novel, small molecule approach to bind G12C mutant K-Ras and inhibit SOS-catalyzed K-Ras activation1. Building upon those pioneering efforts, Wellspring discovered ARS-853, a cell-active, mutant-specific, covalent inhibitor of KRAS G12C that targets the GDP-bound, inactive state and prevents subsequent activation of KRAS2. Wellspring discovered ARS-1620, the first small molecule inhibitor that induced tumor regression in patient-derived tumor models that served as a valuable pharmacologic tool to interrogate KRAS biology in vivo3. Wellspring, through Araxes Pharma, entered into an exclusive arrangement with Janssen in February 2013 to develop small molecule inhibitors of the KRAS G12C oncoprotein for the treatment of cancer. Scientists at both Wellspring and Janssen have made significant contributions in the discovery and development of potent, selective KRAS G12C inhibitors.
