Welireg

(WEL-ih-reg)
A drug used to treat adults with renal cell carcinoma (a type of kidney cancer) that is advanced and adults with certain cancers linked to von Hippel-Lindau disease that do not need surgery right away, including renal cell carcinoma, central nervous system hemangioblastoma (a type of blood vessel tumor), and pancreatic neuroendocrine tumor. It is also being studied in the treatment of other types of cancer. Welireg blocks a certain protein, which may help keep tumor cells from growing and may kill them. It may also prevent the growth of new blood vessels that tumors need to grow. Also called belzutifan.
