The Phase 2 portion of this study evaluates the efficacy and safety of MRTX849 monotherapy and in combination with pembrolizumab in cohorts of patients with advanced NSCLC with KRAS G12C mutation and any PD-L1 TPS and who are candidates for first-line treatment.
The Phase 3 portion of the study compares the efficacy of adagrasib in combination with pembrolizumab versus pembrolizumab in patients with unresectable, locally advanced or metastatic squamous or nonsquamous NSCLC with KRAS G12C mutation and PD-L1 TPS \>=50% and who are candidates for first line treatment.
Phase 2: Histologically confirmed diagnosis of unresectable or metastatic NSCLC with KRAS G12C mutation and any PD-L1 TPS
Phase 3: Histologically confirmed diagnosis of unresectable or metastatic squamous or nonsquamous NSCLC with KRAS G12C mutation and PD-L1 TPS>=50%
Phase 3: Presence of measurable disease per RECIST1.1
No evidence of brain metastases
Phase 2 and Phase 3: Prior systemic treatment for locally advanced or metastatic NSCLC including chemotherapy, immune checkpoint inhibitor therapy, or a therapy targeting KRAS G12C mutation (e.g., AMG 510).
Phase 2: Active brain metastases
