Astellas to Present New Data on Gilteritinib in Multiple Populations of FLT3 Mutation-Positive Acute Myeloid Leukemia (AML) Patients at the 2018 American Society of Hematology (ASH) Annual Meeting

TOKYO, Nov. 19, 2018 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503) (President and CEO: Kenji Yasukawa, Ph.D. "Astellas") today announced it will present new data in Acute Myeloid Leukemia (AML) research at the 60th American Society of Hematology (ASH) Annual Meeting, taking place December 1-4, 2018 in San Diego, California. Among the data being presented are updated results from a Phase 1 study of gilteritinib in combination with induction and consolidation chemotherapy in patients with newly diagnosed AML.

At ASH, collaborating researchers from renowned academic medical centers will present data exploring the use of gilteritinib to treat patients across the FLT3 mutation-positive (FLT3mut+) AML care continuum—from newly diagnosed to relapsed or refractory patients—and on healthcare resource utilization in the current treatment of FLT3mut+ AML. Additionally, Astellas will sponsor two sessions in ASH's Friday Satellite Symposia program prior to the meeting.

"Patients with this life-threatening disease have long had limited treatment options. Developing new therapies that help address unmet medical needs and provide physicians with new tools to treat patients in multiple stages of the FLT3mut+ AML journey is our priority," said Steven Benner, M.D., senior vice president and global therapeutic area head, Oncology Development, Astellas. "We're pleased to present new data at ASH examining the potential for gilteritinib to treat diverse groups of FLT3mut+ AML patients, and to share research on healthcare resource utilization among this patient population."

About Gilteritinib
Gilteritinib is an investigational compound that has demonstrated inhibitory activity against FLT3 internal tandem duplication (ITD) as well as FLT3 tyrosine kinase domain (TKD), two common types of FLT3 mutations that are seen in approximately one-third of patients with AML. Further, gilteritinib has also demonstrated inhibition of the AXL receptor in AML cell lines. Astellas is currently investigating gilteritinib in various AML patient populations through several Phase 3 trials. Visit to learn more about ongoing gilteritinib clinical trials.

Gilteritinib was discovered through a research collaboration with Kotobuki Pharmaceutical Co., Ltd., and Astellas has exclusive global rights to develop, manufacture and potentially commercialize gilteritinib.
