A Phase 3, Randomized, Double-Blind Study of Pembrolizumab plus Ipilimumab vs Pembrolizumab plus Placebo in Previously Untreated, Stage IV, Metastatic Non-small Lung Cancer Subjects Whose Tumors are PD-L1 Positive (TPS 50%) (KEYNOTE-598)
The purpose of this study is to test the effectiveness and safety of the combination of research study drugs, pembrolizumab + ipilimumab, compared to pembrolizumab alone. The study will also test the effectiveness of the research study drug compared to placebo (look-alike with no active ingredients). Pembrolizumab (KEYTRUDA®) and Ipilimumab (Yervoy®) have both been approved by the US Food and Drug Administration (FDA) for the treatment of the disease you have, but the use of these drugs in combination is investigational and can only be given in a research study
You will be put into a group by chance, similar to flipping a coin, in order to decide what type of
study drug you will receive:
Group 1: pembrolizumab + ipilimumab
Group 2: pembrolizumab + placebo (a look-alike with no active ingredients).
Pembrolizumab (200mg) will be administered intravenously every 3 weeks, and each infusion will take about 30 minutes. Ipilimumab or placebo (1mg/kg) will be administered intravenously every 6 weeks, and each infusion will take about 90 minutes.
You have a 50% chance of receiving pembrolizumab + ipilimumab and a 50% chance of
receiving pembrolizumab + placebo.
Neither you nor the study doctor will know what you are receiving. In case of a health emergency, the study doctor can get this information.
This is 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%)
Must have histologically or cytologically confirmed diagnosis of Stage IV metastatic NSCLC

ECOG Performance Status of 0 or 1
Have adequate hematological, renal, hepatic and coagulation organ function
Tumor demonstrates PD-L1 expression in ≥50% of tumor cells (TPS ≥50%) as assessed by IHC as determined by an FDA-approved test (22C3 Pharm IHC PharmDx [Dako] assay) at a central laboratory
Female subjects of childbearing potential must have a negative serum pregnancy test
Male and Female patients of child-bearing potential must use adequate contraceptive during the treatment and for at least 120 days after the last dose of study medication
