Study Summary

Substudy 03A 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 03A is to evaluate the safety and efficacy of experimental combinations of investigational agents in participants with advanced first line (1L) 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.

Primary Outcome

DLTs are defined as one or more of the following toxicities: (1) grade (gr) 4 nonhematologic toxicity (2) gr 4 hematologic toxicity lasting \>7 days OR gr 4 platelet count decreased of any duration OR gr 3 platelet count decreased if associated with bleeding (3) gr 3 nonhematologic toxicity except gr 3 fatigue (lasting ≤3 days), diarrhea, nausea, vomiting or rash without standard of care (4) gr 3 or 4 nonhematologic abnormality if medical intervention is required or if it leads to hospitalizatio
