BASKING RIDGE, N.J. and MUNICH, Nov. 14, 2017 /PRNewswire/ -- Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) today announced it will present data on multiple investigational compounds in the Daiichi Sankyo Cancer Enterprise pipeline at the 2017 San Antonio Breast Cancer Symposium (SABCS), San Antonio, from December 5-9, and the 59th Annual Meeting of the American Society of Hematology (ASH), Atlanta, December 9-12.
Updated data from the ongoing phase 1 study of DS-8201, an investigational HER2-targeting antibody drug conjugate (ADC), in HER2-positive metastatic breast cancer as well as patients with HER2 low-expressing breast cancer will be highlighted as a Spotlight Poster Discussion at SABCS.
Data to be presented at ASH comprises multiple abstracts including preliminary phase 1 data on DS-3201, an investigational dual EZH1/2 inhibitor, in relapsed or refractory non-Hodgkin's lymphomas, a bone marrow and peripheral blood concordance analysis for assessing FLT3-ITD mutated acute myeloid leukemia (AML) from screened patients in the global, randomized phase 3 QUANTUM-R study of quizartinib monotherapy versus salvage chemotherapy in relapsed/refractory AML, and preclinical data supporting the potential role of inhibiting MDM2-p53 interaction as a novel therapeutic strategy for hematological malignancies.
"These data reinforce our commitment to advancing science and accelerating development of several compounds for patients suffering from breast or blood cancer," said Antoine Yver, MD, MSc, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo. "We look forward to sharing further insights on our smart chemotherapy ADC platform and its flagship DS-8201 for HER-2 expressing tumors at SABCS as well as presenting preliminary clinical data on DS-3201, our dual EZH1/2 inhibitor, at ASH."

DS-8201, quizartinib, DS-3201 and DS-5272 are investigational agents that have not been approved for any indication in any country. Safety and efficacy of these investigational agents have not been established.
DS-8201 is the lead product in the ADC Franchise of the Daiichi Sankyo Cancer Enterprise. ADCs are targeted cancer medicines that deliver cytotoxic chemotherapy ("payload") to cancer cells via a linker attached to a monoclonal antibody that binds to a specific target expressed on cancer cells. Using Daiichi Sankyo's proprietary ADC technology, DS-8201 is a smart chemotherapy comprised of a humanized HER2 antibody attached to a novel topoisomerase I inhibitor (DXd) payload by a tetrapeptide-based linker. It is designed to target and deliver chemotherapy inside cancer cells and reduce systemic exposure to the cytotoxic payload (or chemotherapy) compared to the way chemotherapy is commonly delivered.
DS-8201 is currently in phase 2 clinical development for HER2-positive unresectable and/or metastatic breast cancer resistant or refractory to T-DM1 (DESTINY-Breast01) and phase 1 development for other HER2-expressing advanced/unresectable or metastatic solid tumors.
DS-8201 has been granted Breakthrough Therapy designation for the treatment of patients with HER2-positive, locally advanced or metastatic breast cancer who have been treated with trastuzumab and pertuzumab and have disease progression after ado-trastuzumab emtansine (T-DM1), and Fast Track designation for the treatment of HER2-positive unresectable and/or metastatic breast cancer in patients who have progressed after prior treatment with HER2-targeted therapies including T-DM1 by the U.S. Food and Drug Administration (FDA).
The lead product in the AML Franchise of the Daiichi Sankyo Cancer Enterprise, quizartinib is an investigational oral selective FLT3 inhibitor currently in phase 3 development for relapsed or refractory (QuANTUM-R) and newly-diagnosed (QuANTUM-First) AML with FLT3-ITD mutations. Quizartinib has been granted Orphan Drug Designation by the FDA and European Medicines Agency (EMA) for the treatment of AML. Quizartinib also has been granted Fast Track designation by the FDA for the treatment of relapsed or refractory AML.
Part of the AML Franchise of the Daiichi Sankyo Cancer Enterprise, DS-3201 is the first investigational dual EZH1/2 inhibitor currently in phase 1 clinical development for hematologic cancers including acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL) and non-Hodgkin's lymphoma (NHL).
