Trial Summary

What is the purpose of this trial?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.

Eligibility Criteria

This trial is for adults with advanced first line clear cell renal cell carcinoma who haven't had systemic therapy for it. They must be able to take oral meds, have good organ function, and manage contraception if needed. Excluded are those with recent vaccines, multiple cancer treatments, immunodeficiency or other cancers within 3 years.

Inclusion Criteria

My organs are functioning well.

Side effects from my last treatment are mild or gone.

My kidney cancer has spread and is confirmed by tissue analysis.

Participant Groups

The study tests combinations of experimental drugs like Pembrolizumab and others (Favezelimab/Pembrolizumab, Belzutifan) in two phases: a safety phase to ensure tolerability and an efficacy phase without hypothesis testing.
