Summary
Brief summary
This study will investigate the utility of biomarker-based triage for study participants with
advanced non-small cell lung cancer (NSCLC) without prior systemic therapy. Study
participants within groups defined by a biomarker-based classifier (gene expression profile
[GEP] and tumor mutational burden [TMB]) will be randomized to receive pembrolizumab in
combination with quavonlimab (MK-1308), favezelimab (MK-4280), or lenvatinib. The primary
hypotheses are as follows: In participants receiving pembrolizumab in combination with either
quavonlimab, favezelimab, or lenvatinib, the Objective Response Rate (ORR) will be 1) greater
than 5% among participants with low GEP and low TMB, 2) greater than 20% among participants
with low GEP and high TMB, 3) greater than 20% among participants with high GEP and low TMB,
and 4) greater than 45% among participants with high GEP and high TMB.
