A Study of Pembrolizumab (MK-3475) in Combination With Belzutifan (MK-6482) and Lenvatinib (MK-7902), or Pembrolizumab/Quavonlimab (MK-1308A) in Combination With Lenvatinib, Versus Pembrolizumab and Lenvatinib, for Treatment of Advanced Clear Cell Renal Cell Carcinoma (MK-6482-012)

Summary

The goal of this study is to evaluate the efficacy and safety of pembrolizumab plus belzutifan plus lenvatinib or pembrolizumab/quavonlimab plus lenvatinib versus pembrolizumab plus lenvatinib as first-line treatment in participants with advanced clear cell renal cell carcinoma (ccRCC). The primary hypotheses are (1) pembrolizumab plus belzutifan plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to progression-free survival (PFS) and overall survival (OS), in advanced ccRCC participants; and (2) pembrolizumab/quavonlimab plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to PFS and OS, in advanced ccRCC participants.
