Brief summary

This study will evaluate the safety, tolerability, drug levels, molecular effects, and clinical activity of MRTX849 in combination with TNO155 in patients with advanced solid tumors that have a KRAS G12C mutation.

Detailed description

This study will evaluate the safety, tolerability, pharmacokinetics, metabolites, pharmacodynamics, and clinical activity of MRTX849 in combination with TNO155 in patients with advanced solid tumors with a KRAS G12C mutation. MRTX849 is an orally available small molecule inhibitor of KRAS G12C and TNO155 is a selective, orally bioavailable allosteric inhibitor of wild-type SHP2. This study was terminated prior to phase 2 initiating. Only phase 1 of the study was conducted.
