Summary

This trial will study the effects of two drugs, belzutifan and cabozantinib, when taken together by people with advanced kidney cancer. The drugs will be taken orally once daily.

Who is the study for?
This trial is for adults with advanced clear cell renal cell carcinoma (ccRCC). Participants should have measurable tumors, good performance status, and proper organ function. Some can't join if they've had certain treatments for ccRCC or major surgery recently, uncontrolled hypertension, active infections needing treatment, or are in another clinical trial.
What is being tested?
The study tests the effectiveness and safety of combining two oral drugs: Belzutifan and Cabozantinib. It's an open-label Phase 2 study where all participants know which treatment they're getting and take the medications daily to treat advanced kidney cancer.
What are the potential side effects?
Potential side effects from Belzutifan and Cabozantinib may include high blood pressure, fatigue, mouth sores, hand-foot syndrome (redness and pain on palms or soles), diarrhea, decreased appetite, weight loss, nausea/vomiting. Each person's experience with side effects might vary.
