Erdafitinib Overview
-
Erdafitinib is used to treat certain types of urothelial cancer (cancer of the lining of the bladder and other parts of the urinary tract) that spread to nearby tissues or other parts of the body that cannot be removed by surgery and has worsened during or after being treated with other chemotherapy medications. Erdafitinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
