Belzutifan, sold under the brand name Welireg, is a medication used to treat von Hippel–Lindau disease-associated renal cell carcinoma, central nervous system (CNS) hemangioblastoma, or pancreatic neuroendocrine tumor (pNET).[1] It is taken by mouth.[1]

Common side effects include low hemoglobin, tiredness, kidney problems, headache, dizziness, increased blood sugar, and nausea.[1] Other side effects may include low oxygen.[1] Use during pregnancy may harm the baby.[1] It is an hypoxia-inducible factor 2α inhibitor.[1][4]

Belzutifan was approved for medical use in the United States in 2021.[1] In the United Kingdom a month of treatment costs the NHS about £12,000 as of 2022.[4] This amount in the United States costs about 28,000 USD.[5] It is not yet available in Europe.[4]

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.[6]

Dosage

It is generally taken at a dose of 120 mg once per day.[1]

Synthesis

Molecules-27-01643-sch012 (1).jpg

The synthesis (synthetic pathway) of belzutifan goes along six linear steps, starting from the indanone 87.[7][8]

History

Belzutifan is the first drug to be awarded an "innovation passport" from the UK Medicines and Healthcare products Regulatory Agency (MHRA).[9][10]

Belzutifan is the first hypoxia-inducible factor-2 alpha inhibitor therapy approved in the U.S.[11]
