IDHIFA® (enasidenib) is indicated for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) with an isocitrate dehydrogenase-2 (IDH2) mutation as detected by an FDA-approved test. FOR PATIENTS WITH R/R AML AND AN IDH2 MUTATION MYELOID DIFFERENTIATION OPENS UP THE POSSIBILITIES IDHIFA: The first and only oral, targeted inhibitor of IDH2 23 8.2 mo % Rate of complete response (CR)* or CR with partial hematologic recovery (CRh)† Median duration of CR/CRh ‡ n=46/199 (95% CI, 4.3-19.4) n=46/199 (95% CI, 18%-30%) 34 % Rate of conversion from transfusion dependence to transfusion independence (RBC and platelet) n=53/157 IDHIFA was studied in an open-label, single-arm, multicenter, clinical trial of patients with R/R AML and an IDH2 mutation who were assigned a starting dose of 100 mg daily until disease progression or unacceptable toxicity. Dose reductions were allowed to manage adverse reactions. Patients’ IDH2 mutations were either prospectively identified or retrospectively confirmed by the Abbott RealTime™ IDH2 assay. § Patients were a median of 68 years old and had a median of 2 prior therapies. * CR was defined as <5% of blasts in the bone marrow, no evidence of disease, and full recovery of peripheral blood counts (platelets >100,000/μL and AN
