Optimizing Next-Generation AML Therapy: Activity of Mutant IDH2 Inhibitor AG-221 in Preclinical Models

摘要

AG-221 or enasidenib is a first-in-class selective inhibitor of mutated isocitrate dehydrogenase 2 (IDH2) with early demonstrated clinical efficacy in acute myeloid leukemia as a single agent, yet with persistence of mutant IDH2 clones. Two articles in this issue of Cancer Discovery provide further insight into the biological activity of AG-221 in promoting differentiation of IDH2-mutant cells and reversing aberrant DNA methylation over time, and demonstrating preclinical activity in combination with a targeted FLT3 kinase inhibitor to eliminate IDH2-mutant clones.
