Overview
The purpose of this study is to evaluate the efficacy of an investigational RAS(ON) inhibitor administered in combination with pembrolizumab and platinum-based chemotherapy doublet compared to placebo in combination with pembrolizumab and platinum-based chemotherapy doublet.
Description
This is a Phase 3, global, randomized, double-blind study designed to evaluate whether treatment with zoldonrasib in combination with pembrolizumab and platinum-based chemotherapy doublet will improve progression-free survival compared to placebo in combination with pembrolizumab and platinum-based chemotherapy doublet when given to patients with previously untreated, 1L metastatic RAS G12D-mutated, non-squamous non-small cell lung cancer (NSCLC).
Patients will be randomized to one of two arms: zoldonrasib + pembrolizumab + platinum-based chemotherapy doublet (Arm A) or placebo + pembrolizumab + platinum-based chemotherapy doublet (Arm B).

- Known PD-L1 status
- Documented RAS G12D mutation status.
- Measurable disease per RECIST v1.1.
- Adequate organ function (bone marrow, liver, kidney, coagulation, thyroid).
- Able to take oral medications.
Exclusion Criteria:
- Prior treatment with systemic anticancer therapy in metastatic setting for NSCLC.
- Prior systemic therapy with any RAS-directed therapy.
- Untreated (symptomatic or asymptomatic) central nervous system metastatic disease.
- Any conditions that may affect the ability to take or absorb study drug.
- Major surgery on or within 28 days prior to randomization.
