Brief Summary:

This is a study evaluating the efficacy and safety of MK-1084 with pembrolizumab as first-line treatment in participants with metastatic non-small cell lung cancer (NSCLC) with identified Kirsten rat sarcoma viral oncogene homolog G12C (KRAS G12C) mutation and programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥50%. There are two primary study hypotheses:

Hypothesis 1: Combination of MK-1084 and pembrolizumab is superior to placebo plus pembrolizumab with respect to progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).

Hypothesis 2: Combination of MK-1084 plus pembrolizumab is superior to placebo plus pembrolizumab with respect to overall survival (OS).

  3. Number of Participants Who Experience One or More Adverse Event (AEs) [ Time Frame: Up to approximately 57 months ]
    An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. The number of participants who experience an AE will be presented.
