A Phase 3, Randomized, Double-Blind Study of Pembrolizumab plus Ipilimumab vs Pembrolizumab plus Placebo in Previously Untreated, Stage IV, Metastatic Non-small Cell Lung Cancer Subjects Whose Tumors are PD-L1 Positive (TPS = 50%) (KEYNOTE-598)

The purpose of this study is to determine the efficacy of pembrolizumab given in combination with either ipilimumab or placebo as first-line treatment in participants with metastatic non-small cell lung cancer (NSCLC). The primary hypothesis of this study is that overall survival (OS) and/or progression-free survival (PFS) is prolonged in participants who receive pembrolizumab and ipilimumab compared to those who receive pembrolizumab and placebo.
