So, Erdafitinib is this oral medicine that’s used to treat a type of cancer called metastatic urothelial carcinoma, especially when there are changes in the FGFR2/3 genes. It basically stops the FGFR signals from doing their thing. You can get this drug in different strengths—3, 4, or 5 milligrams.
The usual amount they start with is 8 milligrams a day, but they might go up to 9 if needed. These tablets come in bottles with 56 of them. The main part of the drug blocks this FGFR pathway, which is really important for cancer cells to grow and spread in urothelial carcinoma.
The dose depends on whether the patient has these FGFR2/3 changes and how they handle the med. This is a last resort kind of drug—used when nothing else works or when it’s not a good option. And it goes by the brand name Balversa too.
