Abstract
Acute myeloid leukemia (AML) is the most common adult leukemia, with an overall poor prognosis. New agents targeting various receptors may improve treatment outcomes and overall survival. FMS-like tyrosine kinase 3 (FLT3) is a targetable mutation occurring in one third of AML patients. It contributes to increased tumor proliferation and decreased cellular differentiation, ultimately conferring a poor overall prognosis. Among patients with FLT3-positive relapsed/refractory AML, outcomes are particularly dismal. Gilteritinib is a novel, second-generation FLT3 inhibitor approved by the U.S. Food & Drug Administration (FDA) for the treatment of relapsed/refractory AML with an FLT3 mutation as detected by an FDA-approved test.
