Summary
The primary hypothesis is that pembrolizumab/vibostolimab (MK-7684A) in combination with chemotherapy is superior to pembrolizumab in combination with chemotherapy with respect to overall survival (OS) in participants with programmed cell death-ligand 1 (PD-L1) tumor proportion score (TPS) ≥1%.
