Official title

A Phase 3, Randomized, Double-Blind, Placebo-Controlled Clinical Trial of Pembrolizumab (MK-3475) as Monotherapy in the Adjuvant Treatment of Renal Cell Carcinoma Post Nephrectomy (KEYNOTE-564)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
