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."
About Quizartinib
Quizartinib, an oral FLT3 inhibitor, is the lead product in the AML Franchise of Daiichi Sankyo. Quizartinib currently is approved for use in Japan under the brand name VANFLYTA® for the treatment of adult patients with relapsed/refractory FLT3-ITD AML, as detected by an approved test. It was launched in Japan on October 10, 2019.
Enrollment into QuANTUM-First, a global, pivotal phase 3 study evaluating quizartinib in combination with standard chemotherapy in newly diagnosed FLT3-ITD AML, was recently completed.
Other ongoing studies include phase 1/2 development for pediatric and young adult relapsed/refractory FLT3-ITD AML in North America and Europe; and phase 1 development in combination with milademetan, an investigational MDM2 inhibitor, for relapsed/refractory FLT3-ITD AML and newly-diagnosed FLT3-ITD AML unfit for intensive chemotherapy in the U.S. Milademetan is an investigational agent that has not been approved for any indication in any country. Safety and efficacy have not been established.
About FLT3-ITD AML
AML is an aggressive blood and bone marrow cancer that causes uncontrolled growth and accumulation of malignant white blood cells that fail to function normally and interfere with the production of normal blood cells.2 In the EU, there are approximately 18,000 new cases of AML each year,3 and their five-year survival rate is less than 30 percent.4
FLT3 gene mutations are one of the most common genetic abnormalities in AML.5 FLT3-ITD is the most common FLT3 mutation, affecting approximately one in four patients with AML.6 FLT3-ITD is a driver mutation that presents with high leukemic burden, a poor prognosis and a significant impact on disease management for patients with AML.7 Patients with FLT3-ITD AML have a worse overall prognosis, including an increased incidence of relapse, an increased risk of death following relapse and a higher likelihood of relapse following hematopoietic stem cell transplantation, as compared to those without this mutation.8,9
