Belzutifan, sold under the brand name Welireg, is a medication used for the treatment of von Hippel–Lindau disease-associated renal cell carcinoma.[2][3][4][5][6][7] It is taken by mouth.[2]

The most common side effects include decreased hemoglobin, anemia, fatigue, increased creatinine, headache, dizziness, increased glucose, and nausea.[3]

Belzutifan is an hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor.[2][3][8]

Belzutifan is the first drug to be awarded an "innovation passport" from the UK Medicines and Healthcare products Regulatory Agency (MHRA).[9][5] Belzutifan was approved for medical use in the United States in August 2021.[3][10] Belzutifan is the first hypoxia-inducible factor-2 alpha inhibitor therapy approved in the U.S.[10]

Medical uses

Belzutifan is indicated for treatment of adults with von Hippel-Lindau (VHL) disease who require therapy for associated renal cell carcinoma (RCC), central nervous system (CNS) hemangioblastomas, or pancreatic neuroendocrine tumors (pNET), not requiring immediate surgery.[3] Belzutifan was also found to be efficacious in an adolescent who had Pacak–Zhuang syndrome with polycythemia and paragangliomas.[11]
