Daiichi Sankyo Quizartinib NDA for Acute Myeloid Leukemia
FDA has accepted for priority review a Daiichi Sankyo NDA for quizartinib for treating adult patients with relapsed/refractory FLT3-ITD acute myeloid leukemia (AML). The agency set a user fee review action target date of 5/25/2019.
The NDA is based on results from the Phase 3 QuANTUM-R study of quizartinib, which showed that the FLT3 inhibitor prolonged overall survival compared to chemotherapy in patients with relapsed/refractory FLT3-ITD AML. The most common adverse drug reactions in patients treated with quizartinib included infections, bleeding, nausea, asthenic conditions, pyrexia, febrile neutropenia and vomiting.
