This is a non-randomized, open-label, single arm, multicenter, phase II study evaluating the antitumor activity and safety of JDQ443 single agent as first-line treatment for participants with locally advanced or metastatic KRAS G12C-mutated NSCLC. The study will have 2 non-comparative cohorts (Cohort A and B) that will recruit participants in parallel.~The study treatment begins on Cycle 1 Day 1 (C1D1) with the first administration of JDQ443. Each cycle is 21 days.~Study completion is defined as the earliest occurrence of one of the following:~The last participant completes last study visit (and the assessments associated with this visit have been documented and followed-up appropriately by the Investigator), dies, withdraws consent or is lost to follow-up, whichever comes first.~In the event of an early study termination decision, the date of that decision.~Another clinical study becomes available that can continue to provide JDQ443 to study participants and all participants with ongoing treatment are transferred to that clinical study.
This study aims to assess the antitumor activity and safety of JDQ443 single-agent as first-line treatment for participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors harbor a KRAS G12C mutation and a PD-L1 expression < 1% regardless of STK11 mutation status (cohort A), or a PD-L1 expression ≥ 1% and an STK11 co-mutation (cohort B).
