FDA Priority Review for Celgene Leukemia Drug
FDA has accepted for priority review a Celgene NDA for enasidenib (AG-221/CC-90007) for treating patients with relapsed or refractory acute myeloid leukemia (AML) with an isocitrate dehydrogenase 2 (IDH2) mutation. The agency has set a user fee review target date of 8/30.
The company says enasidenib is a first-in-class, oral, targeted inhibitor of mutant IDH2. The submission is based on results from AG221-C-001, a single-arm Phase 1-2 study of enasidenib in patients with advanced hematologic malignancies with an IDH2 mutation. Celgene is also evaluating enasidenib compared with conventional therapy in older patients with an IDH2 mutation and relapsed or refractory AML in an ongoing phase 3 trial called IDHENTIFY.
