For which conditions is this drug approved? Inlyta is approved for the treatment of advanced renal cell carcinoma (kidney cancer) when prior treatment hasn’t worked.

These drugs work by blocking the action of enzymes called kinases, which are involved in many cell functions, including cell signaling, growth, and division.
