Detailed Description

This study will evaluate the safety, tolerability, pharmacokinetics, metabolites, pharmacodynamics, and clinical activity of MRTX849 (adagrasib) in patients with advanced solid tumors with a KRAS G12C mutation. MRTX849 (adagrasib) is an orally-available small molecule inhibitor of KRAS G12C.
