The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) PLUS chemotherapy in combination with vibostolimab (MK-7684), MK-5890, or MK-4830 in treatment-naïve participants with advanced squamous or non-squamous NSCLC.

This study is one of three pembrolizumab substudies being conducted under one pembrolizumab umbrella master protocol (MK-3475-U01/KEYMAKER-U01).


The master screening protocol is MK-3475-U01 (KEYMAKER-U01) - NCT04165798
