Bristol Myers Squibb announced that the Phase 3 IDHENTIFY study evaluating IDHIFA® (enasidenib) plus best supportive care (BSC) versus conventional care regimens, which include best supportive care (BSC) only, azacitidine plus BSC, low-dose cytarabine plus BSC or intermediate-dose cytarabine plus BSC, did not meet the primary endpoint of overall survival (OS) in patients with relapsed or refractory acute myeloid leukemia (R/R AML) with an isocitrate dehydrogenase-2 (IDH2) mutation. The safety profile of IDHIFA was consistent with previously reported findings. The company will complete a full evaluation of the IDHENTIFY data and work with investigators to present detailed results at a future medical meeting.
“While we are disappointed by the outcome of the IDHENTIFY study, we remain confident in IDHIFA’s established role as a treatment option for patients with relapsed or refractory AML with an IDH2 mutation and are grateful to all those who participated in the study,” said Noah Berkowitz, M.D., Ph.D., senior vice president, Global Clinical Development, Hematology, Bristol Myers Squibb. “AML is one of the most difficult-to-treat blood cancers, and we’re committed to furthering our research and improving on the standards of care for patients living with this aggressive disease.”
In August 2017, Bristol Myers Squibb received full approval in the U.S. for IDHIFA for the treatment of adult patients with R/R AML with an IDH2 mutation as detected by a U.S. Food and Drug Administration (FDA)-approved test. IDHIFA is the first and only FDA-approved therapy for patients with R/R AML and positive for an IDH2 mutation, which represents up to 19 percent of AML patients. IDHIFA is also approved in Australia and Canada.
