Clinical Trial Summary

Substudy 03B is part of a larger research study that is testing experimental treatments for renal cell carcinoma (RCC). The larger study is the umbrella study (U03). The goal of substudy 03B is to evaluate the safety and efficacy of experimental combinations of investigational agents in participants with advanced second line plus (2L+) clear cell renal cell carcinoma (ccRCC). This substudy will have two phases: a safety lead-in phase and an efficacy phase. The safety lead-in phase will be used to demonstrate a tolerable safety profile for the combination of investigational agents. There will be no hypothesis testing in this study.

Responses are according to RECIST 1.1 by BICR. Up to ~56 months
