Phase 3 Study Comparing Sotorasib Plus Chemotherapy to Pembrolizumab Plus Chemotherapy for Advanced Nonsquamous Non-Small Cell Lung Cancer with KRAS p.G12C Mutation and No PD-L1

What this Trial Is About

Researchers are comparing two treatment combinations for adults with advanced nonsquamous non-small cell lung cancer NSCLC that have a specific KRAS p.G12C mutation and are negative for PD-L1 expression. The study aims to evaluate progression-free survival and overall survival between participants receiving sotorasib with platinum doublet chemotherapy and those receiving pembrolizumab with platinum doublet chemotherapy. This phase 3, randomized, open-label trial is led by Amgen and includes participants with stage IV or advanced stage IIIBC NSCLC. Participants will be randomly assigned to receive either sotorasib orally combined with carboplatin and pemetrexed, or pembrolizumab intravenously combined with the same chemotherapy drugs. These treatments are given as front-line therapy. The study includes a treatment period with these drug combinations and monitoring for outcomes such as response rates and quality of life over several years. During the study, participants will be regularly assessed through various measures including survival status, tumor response, and quality-of-life questionnaires focusing on lung cancer symptoms. Researchers will monitor safety by tracking adverse events, vital signs, and laboratory tests. Treatment concentrations of sotorasib will also be measured up to 64 days after starting. The total study duration includes follow-up for up to approximately 5.5 years to fully evaluate treatment effects and outcomes.
