Daiichi Sankyo Receives Negative CHMP Opinion for FLT3 Inhibitor Quizartinib for Treatment of Patients with Relapsed/Refractory FLT3-ITD AML

- Global clinical development program of quizartinib continues with focus on newly-diagnosed FLT3-ITD AML with enrollment completed into pivotal phase 3 QuANTUM-First study  

TOKYO and MUNICH, Oct. 18, 2019 /PRNewswire/ -- Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) today announced the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a negative opinion on the Marketing Authorization Application (MAA) for quizartinib for the treatment of adults with relapsed/refractory FLT3-ITD acute myeloid leukemia (AML).

The CHMP opinion is based on the MAA submission of data from the global pivotal QuANTUM-R study of quizartinib. Results from QuANTUM-R were published in The Lancet Oncology.¹

"While we are disappointed by this opinion, we will evaluate feedback received from the CHMP in order to determine next steps for quizartinib for the treatment of patients with relapsed/refractory FLT3-ITD AML in Europe," said Antoine Yver, MD, MSc, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo. "Despite this setback, we continue to believe in the potential benefit of quizartinib for patients with FLT3-ITD AML and we look forward to the results of the global, pivotal phase 3 QuANTUM-First study evaluating quizartinib in combination with chemotherapy for patients with newly-diagnosed FLT3-ITD AML. We remain committed to bringing quizartinib forward as a potential treatment option for this aggressive and difficult-to-treat subtype of AML in the U.S., Europe and other parts of the world."
