Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) announced that the first patient has been enrolled in the global phase 3 QuANTUM-First study evaluating the oral FLT3-ITD inhibitor quizartinib in patients with newly-diagnosed FLT3-ITD-positive (+) acute myeloid leukemia (AML).
QuANTUM-First is a randomized, double-blind, placebo-controlled study evaluating quizartinib in combination with induction and consolidation chemotherapy and as maintenance monotherapy in patients with newly-diagnosed FLT3-ITD+ AML. The primary endpoint of the study is event-free survival. Secondary endpoints include overall survival, complete remission rate, composite complete remission rate and the percentage of subjects achieving a complete remission with no evidence of minimal residual disease.
“It is well established that patients with FLT3-ITD mutated AML have an overall worse prognosis compared to those without this specific mutation,” said Harry Erba, MD, PhD, Chair of the QuANTUM-First Steering Committee and Professor of Medicine and Director of the Hematologic Malignancy Program at the University of Alabama at Birmingham. “In this study we are evaluating whether adding quizartinib to standard first-line chemotherapy will help delay or prevent relapse, which in turn may impact overall survival in patients with FLT3-ITD+ AML.”
“Given the high unmet need in FLT3-ITD+ AML, we are moving forward with a comprehensive clinical development program investigating the role of quizartinib in multiple lines of treatment including induction and consolidation chemotherapy, maintenance therapy and salvage therapy,” said Antoine Yver, MD, MSc, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo.
“Additionally, we also are looking to combine quizartinib with other investigational agents in our pipeline such as our MDM2 and BRD4 inhibitors where science suggests combining different mechanisms of action may help improve outcomes.”
