Ponatinib is used to treat a certain type of chronic myeloid leukemia (CML; a type of cancer of the white blood cells), including treatment in people who can no longer benefit from other medications for CML or who cannot take these medications because of side effects. Ponatinib is also used to treat a certain type of acute lymphoblastic leukemia (ALL; a type of cancer of the white blood cells) in people who can no longer benefit from other medications for leukemia or who cannot take these medications because of side effects. Ponatinib 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 stop the spread of cancer cells.
