Official study title

Study of Pembrolizumab/Vibostolimab (MK-7684A) in Combination With Concurrent Chemoradiotherapy Followed by Pembrolizumab/Vibostolimab Versus Concurrent Chemoradiotherapy Followed by Durvalumab in Participants With Stage III Non-small Cell Lung Cancer (MK-7684A-006)

Study summary

Researchers are looking for new ways to treat people with locally advanced non-small cell lung cancer (NSCLC). The goal of this study is to learn if people who receive the combination of vibostolimab and pembrolizumab (MK-7684A) live longer without the cancer getting worse and live longer overall than people who receive durvalumab.
