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).

- ✓ Provides an archival tumor tissue sample (≤5 years) or newly obtained core, incisional, or excisional biopsy of a tumor lesion not previously irradiated to enable central laboratory testing of kirsten rat sarcoma (KRAS) G12C mutation status, PD-L1 status, and biomarker research
- ✓ If have had adverse events (AEs) due to previous anticancer therapies, must have recovered to \< Grade 1 or baseline
- ✓ If human immunodeficiency virus (HIV)-infected, must have well controlled HIV on antiretroviral therapy (ART)
- ✓ If Hepatitis B surface antigen (HBsAg) positive, have received Hepatitis B Virus (HBV) antiviral therapy for at least 4 weeks, and have undetectable HBV viral load
- ✓ If a participant has a history of Hepatitis C virus (HCV) infection, HCV viral load is undetectable
You may not qualify if…
