Purpose

The main purpose of this study is to evaluate the efficacy of divarasib compared with investigator's choice of immunotherapy (pembrolizumab or nivolumab) or observation in participants with resected Kirsten rat sarcoma viral oncogene homolog glycine 12 to cysteine (KRAS G12C)-positive Stage II-IIIB NSCLC, regardless of tumor programmed death-ligand 1 (PD-L1) status, who have not achieved pathologic complete response (pCR) following neoadjuvant chemoimmunotherapy.
