ASH: Survival benefit of Daiichi Sankyo's FLT3 inhibitor quizartinib

4 December 2018

Japanese pharma major Daiichi Sankyo (TYO: 4568) yesterday announced positive comprehensive analyses of overall survival from the pivotal QuANTUM-R Phase III study of single agent quizartinib compared to salvage chemotherapy in patients with FLT3-ITD acute myeloid leukemia (AML), which was refractory or relapsed within six months of first remission, at the 60th Annual Meeting of the American Society of Hematology (ASH) in San Diego.

The company’s shares closed the day up 2.98% at 4,291 yen.

Pre-specified sensitivity analyses of overall survival and event-free survival as well as predefined subgroup analyses from the QuANTUM-R study of quizartinib were found to be consistent with the primary analysis of overall survival. Analyses of key exploratory endpoints such as composite complete remission (CRc), duration of CRc and hematopoietic stem cell transplant (HSCT) rate also were consistent with, and supportive of, the primary overall survival benefit demonstrated in QuANTUM-R.
