TOKYO, Dec. 1, 2021 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Kenji Yasukawa, Ph.D., "Astellas") today announced the presentation of new investigational data in acute myeloid leukemia (AML) and sickle cell disease at the 63rd American Society of Hematology (ASH) Annual Meeting and Exposition, taking place December 11-14, in Atlanta, Ga. Astellas' largest ASH showing to date includes 11 AML abstracts, including four oral presentations.
"Research being presented at this year's ASH meeting investigates gilteritinib across the FLT3-mutation-positive AML disease continuum," said Ahsan Arozullah, M.D., M.P.H., Vice President, Medical Sciences-Oncology, Astellas. "Several presentations highlight data for gilteritinib in a wide range of patients – from newly diagnosed to relapsed or refractory patients, and in varying combination regimens."
Presentations will include results from two Phase 3 trials: three abstracts from LACEWING, a clinical trial which included patients with newly diagnosed FLT3 mutation-positive (FLT3mut+) AML who were ineligible for first-line intensive induction chemotherapy; and one from COMMODORE, a trial of gilteritinib versus salvage chemotherapy in patients with FLT3mut+ relapsed or refractory AML conducted in China, Malaysia, Thailand, Singapore, and Russia.
Astellas will also present research based on patients' perspectives of AML symptoms, life impact and treatment. "A deeper understanding of patient experiences is vital as we seek better treatment approaches in all stages of AML," said Erhan Berrak, M.D., Vice President of Medical Affairs, Oncology, Astellas. "For example, one study to be presented at this year's ASH meeting investigated the patient experience after a stem-cell transplant, shedding light on both symptoms and emotional impact, which can inform efforts to better serve patients post-transplant."
In addition, Astellas plans to present new preclinical data on sickle cell disease (SCD) for ASP8731, a novel BACH1 inhibitor that potentially induces fetal hemoglobin (HbF). The data show potential to increase expression of antioxidant and HbF genes and reduce SCD-related pathophysiology. This may result in the reduction of hemolysis, inflammation, and vaso-occlusive pain crises in patients living with the condition.
"We are pleased to have the opportunity to present our preclinical data supporting further development of ASP8731, our BACH1 inhibitor," said Itsuro Nagase, Ph.D., D.V.M., Vice President and Primary Focus Lead, Mitochondrial Biology, Astellas. "These data further support our focus on mitochondrial disease research and the advances we are making across the Astellas research pipeline to develop novel therapies for patients with unmet medical needs."

About Acute Myeloid Leukemia (AML)
Acute myeloid leukemia (AML) is an aggressive cancer that affects the bone marrow and blood, and its incidence increases with age.1,2 Of patients newly diagnosed with AML and tested for FLT3 mutations, approximately one-third have an alteration to the FLT3 gene. FLT3-ITD mutations have been associated with worsened disease-free survival and overall survival, and a higher risk of getting the disease more than once. FLT3 mutation status can change over the course of AML treatment, even after relapse.3-6
Gilteritinib is an FMS-like tyrosine kinase 3 (FLT3) inhibitor with demonstrated activity against FLT3-ITD, a common driver mutation that presents with a high disease burden and poor prognosis, and FLT3-TKD mutations.7 It was discovered through a research collaboration with Kotobuki Pharmaceutical Co., Ltd., and Astellas has exclusive global development, commercialization and manufacturing rights to gilteritinib.8
