Could this be for you?

Answer for yourself. This is not a decision: only the study team can say whether you can take part.

  • Are you between 18 and 100 years old?
  • Which best describes your lung cancer?
  • Has the cancer spread to other parts of the body, or is it too advanced to be removed by surgery?
  • What was the PD-L1 result of your tumour test?
  • Has your cancer spread to the brain?

G12C mutation and negative for PD-L1 expression by central testing or local laboratory testing confirmed through central testing; No history of systemic anticancer therapy in metastatic/non-curable settings; Eastern Cooperative Oncology Group (ECOG) ≤ 1.

Exclusion: Participants with tumors known to harbor molecular alterations for which targeted therapy is locally approved as a front-line therapy; Prior therapy with a KRAS G12C inhibitor; Gastrointestinal (GI) tract disease causing the inability to take oral medication; Myocardial infarction within 6 months of randomization, unstable arrhythmias, or unstable angina; Mixed histology NSCLC with either small-cell or large-cell neuroendocrine cell component or predominant squamous cell histology; Symptomatic (treated or untreated) brain metastases.
