Trial Purpose
The purpose of this study is to assess the efficacy and safety of treatment with definitive chemoradiotherapy (dCRT) + pembrolizumab (MK-3475) compared to treatment with dCRT + placebo with respect to Event-free Survival (EFS) and Overall Survival (OS) in:
participants whose tumors express Programmed Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10
participants whose tumors express PD-L1 CPS ≥1
all participants
The primary study hypotheses are that dCRT+ pembrolizumab is better than dCRT + placebo with respect to:
EFS in participants whose tumors express PD-L1 CPS ≥10
EFS in participants whose tumors express PD-L1 CPS ≥1
EFS in all participants
OS in participants whose tumors express PD-L1 CPS ≥10
OS in participants whose tumors express PD-L1 CPS ≥1
OS in all participants

Current trial phase
Trial Phase 3
In Phase 3 trials, researchers try to find out if a treatment works in a large number of people, usually about 1,000 to 5,000 participants who have the health condition the treatment is intended to treat. In vaccine trials, the participants may be healthy or have diseases or conditions. Phase 3 trials may happen in a doctor’s office, a clinic, or a hospital.
