A Study to Evaluate the Efficacy and Safety of Divarasib Compared With Investigator's Choice of Immunotherapy or Observation in Participants With Resected Stage II-III KRAS G12C-Positive Non-Small Cell Lung Cancer (NSCLC)
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.

Who may be able to participate
The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
- Histological or cytological diagnosis of clinical Stage II-IIIB NSCLC of either non-squamous or squamous histology
- Participants must have had complete resection of NSCLC
- Prior treatment with neoadjuvant immune checkpoint inhibitor (pembrolizumab or nivolumab) in combination with histology-based platinum-based doublet chemotherapy
- Participants must be randomized within 12 weeks of their surgery date
- No evidence of disease recurrence or metastatic disease
- Documentation of the presence of a KRAS G12C mutation
- Participants who achieve pCR following neoadjuvant treatment
- Prior treatment with a KRAS inhibitor or any other anti-cancer therapy not otherwise specified in the protocol
- Prior treatment with radiation therapy for NSCLC, with the exception of localized symptom-directed radiation prior to surgical resection
- Resolved Grade 3 or greater immune-related AE or unresolved Grade 2 or greater immune-related AE from neoadjuvant immunotherapy
- Active or history of autoimmune disease or immune deficiency
- Significant cardiovascular disease
Important: This is the sponsor’s public criteria, not a determination of eligibility. The study team must review your individual situation.
