Enasidenib for the treatment of acute myeloid leukemia.

Enasidenib for the treatment of acute myeloid leukemia. Expert Rev Clin Pharmacol. 2018 May 17;: Authors: Dugan J, Pollyea D Abstract INTRODUCTION: In August 2017 the United States Federal Drug Administration (FDA) approved enasidenib (Idhifa, Celgene/Agios) for adults with relapsed and refractory acute myelogenous leukemia (AML) with an IDH2 mutation. Enasidenib targets cells with mutant copies of isocitrate dehydrogenase-2 (IDH2), inhibiting the oncometabolite 2-hydroxyglutarte (2-HG) formed by the mutant IDH2. Areas covered: We review the studies leading to enasidenib's approval, as well as common side effects and safety issues experienced during the clinical trials. There is a focus on the diagnosis and treatment of these side effects including differentiation syndrome. Expert commentary: We are experiencing a revolution in the understanding of the mechanism of AML. A majority of the effort has been concentrated on targeting gene mutations or pathway activations with precision therapeutics. Enasidenib is beneficial in a patient population that previously had limited treatment options. However, given the fact that enasidenib is a highly specific inhibitor of an early stable mutation, it is questionable whether a strategy of targeting a single mutation or pathway in relapsed AML will allow for better than the 20% complete remission (CR) rate observed with this therapy. The proper role for single mutation targeting in AML needs to b...
