In Brief

A Phase 3 clinical trial evaluating Pembrolizumab and Placebo for Renal Cell Carcinoma. Completed, enrolled 994 participants across 251 sites in 21 countries.

Detailed Summary

The purpose of this study is to evaluate the safety and efficacy of pembrolizumab (MK-3475) in the adjuvant treatment of adult participants who have undergone nephrectomy and have intermediate-high risk, high risk, or M1 no evidence of disease (M1 NED) renal cell carcinoma (RCC) with clear cell component. The primary study hypothesis is that pembrolizumab is superior to placebo with respect to Disease-free Survival (DFS) as assessed by the Investigator in male and female participants with intermediate-high risk, high risk and M1 NED RCC.
