Phase 2 Trial of MRTX849 Monotherapy and in Combination With Pembrolizumab for NSCLC With KRAS G12C Mutation KRYSTAL-7

This Phase 2 study will evaluate the efficacy and safety of MRTX849 as monotherapy and in combination with pembrolizumab. There will be 3 cohorts of patients, all of whom have KRAS G12C mutation, have advanced or metastatic NSCLC, and are candidates for first-line treatment. 2 cohorts have PDL-1 TPS score <1% and are randomized to MRTX849 monotherapy or MRTX849 in combination with pembrolizumab. The 3rd cohort has PDL-1 TPS score of 1% or higher and is treated with MRTX849 and pembrolizumab

MRTX849 is an orally available small molecule inhibitor of KRAS G12C, and Pembrolizumab (KEYTRUDA®) is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2.
