ℹ️ 1. What Xospata is and what it is used for

What Xospata is Xospata belongs to a class of cancer medicines called protein kinase inhibitors. It contains the active substance gilteritinib.

What Xospata is used for

Xospata is used to treat adults with acute myeloid leukaemia (AML), a cancer of certain white blood cells. Xospata is used if AML is linked to an alteration of a gene called FLT3, and is given to patients whose disease has come back or has not improved after previous treatment.

How Xospata works

In AML, patients develop large numbers of abnormal white blood cells. Gilteritinib blocks the action of certain enzymes (kinases) needed for the abnormal cells to multiply and grow, thus preventing the growth of the cancer.
