To learn if belzutifan can help to control the disease in patients with metastatic RCC who are considered candidates for active surveillance and have not undergone previous systemic treatment. The safety of belzutifan in this patient population will also be studied.
Metastatic clear cell renal cell carcinoma, with or without sarcomatoid features, clinically apparent less than 12 months.
Male/female participants must be at least 18 years of age on the day of signing informed consent.
IMDC risk score of 0 or 1.
No prior systemic treatment for ccRCC. Adjuvant immunotherapy or targeted treatments allowed if progressive disease is noted at least 12 months after last dose of immunotherapy.
Known or suspected brain metastases or active leptomeningeal disease.
Requires any supplemental oxygen (either intermittent or chronic)
Other concurrent severe and/or uncontrolled concomitant medical conditions (e.g., active or uncontrolled infection) that could cause unacceptable safety risks or compromise compliance with protocol
Impairment of gastrointestinal function or disease that may significantly alter the absorption of belzutifan (e.g., uncontrolled nausea, vomiting, diarrhea, malabsorption syndromes, prior small bowel resection, or inflammatory bowel disease)
