About this study

This is a study evaluating the efficacy and safety of calderasib with pembrolizumab as first-line treatment in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) with identified Kirsten rat sarcoma viral oncogene homolog G12C (KRAS G12C) mutation and programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥50%. There are two primary study hypotheses: Hypothesis 1: Combination of calderasib and pembrolizumab is superior to placebo plus pembrolizumab with respect to progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR). Hypothesis 2: Combination of calderasib plus pembrolizumab is superior to placebo plus pembrolizumab with respect to overall survival (OS).
