Belzutifan Overview
-
Belzutifan is used in adults with von Hippel-Lindau disease (VHL; a rare disease that causes tumors and cysts) to treat renal cell carcinoma (RCC; kidney cancer), central nervous system (CNS) hemangioblastomas (tumors in the brain and spinal cord), and a certain type of pancreatic cancer that does not require surgery right away. Belzutifan is in a class of medications called hypoxia-inducible factor inhibitors. It works by blocking the activity of a certain protein in people with VHL.
