Daiichi Sankyo Demonstrates Breadth and Depth of Oncology Portfolio Across Multiple Cancers with New Data at ESMO Asia, SABCS and ASH

Daiichi Sankyo (TSE: 4568) will present new clinical research across its oncology portfolio in multiple types of solid and blood cancers at the 2023 ESMO Asia Congress (#ESMOAsia23), San Antonio Breast Cancer Symposium (#SABCS23) and American Society of Hematology (#ASH23) Annual Meeting prior to its annual R&D Day.

  • Annual R&D Day to provide overview of data and updated strategy across Daiichi Sankyo R&D pipeline

BASKING RIDGE, N.J.--(BUSINESS WIRE)-- Daiichi Sankyo (TSE: 4568) will present new clinical research across its oncology portfolio in multiple types of solid and blood cancers at the 2023 ESMO Asia Congress (#ESMOAsia23), San Antonio Breast Cancer Symposium (#SABCS23) and American Society of Hematology (#ASH23) Annual Meeting prior to its annual R&D Day.

Presentation highlights include the first presentation of results from three trials from Daiichi Sankyo’s DXd ADC and hematology portfolio, which include the DESTINY-Gastric06 phase 2 trial of ENHERTU® (trastuzumab deruxtecan) in Chinese patients with previously treated HER2 positive locally advanced/metastatic gastric cancer or gastroesophageal junction adenocarcinoma at ESMO Asia, the DESTINY-Breast08 phase 1b trial of ENHERTU in combination with anastrozole or fulvestrant in patients with HER2 low metastatic breast cancer at SABCS and the VALENTINE-PTCL01 phase 2 trial of valemetostat in patients with relapsed/refractory peripheral T-cell lymphoma (PTCL) at ASH.

“Our goal is to push the boundaries of science to change the way cancer is treated,” said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. “These data reinforce the breadth and depth of our oncology pipeline and the important progress we are making in developing innovative medicines and exploring combination strategies for patients across a wide range of cancers, including breast, lung, gastric, acute myeloid leukemia and peripheral T-cell lymphoma.”

Subgroup analyses of the TROPION-Lung05 phase 2 trial of datopotamab deruxtecan (Dato-DXd) in Asian patients with non-small cell lung cancer (NSCLC) with actionable genomic alterations and the DESTINY-Lung02 phase 2 trial of ENHERTU in Asian patients with HER2 mutant NSCLC will be presented at ESMO Asia. Additional subgroup analyses of the QuANTUM-First phase 3 trial in patients with newly diagnosed FLT3-ITD positive acute myeloid leukemia (AML), which formed the basis of recent approvals of VANFLYTA® (quizartinib) in the EU, Japan and U.S. will be presented at ASH.

Daiichi Sankyo will hold its annual R&D Day for investors, analysts and media on Monday, December 11 at 5:30 - 7:00 pm EST/Tuesday, December 12 at 7:30 - 9:00 am JST. Company executives will provide highlights of Daiichi Sankyo’s research data presented at SABCS and ASH, as well as updates on the company’s R&D strategy.

About the DXd ADC Portfolio of Daiichi Sankyo
The DXd ADC portfolio of Daiichi Sankyo currently consists of six ADCs in clinical development across multiple types of cancer. ENHERTU, a HER2 directed ADC, and datopotamab deruxtecan (Dato-DXd), a TROP2 directed ADC, are being jointly developed and commercialized globally with AstraZeneca. Patritumab deruxtecan (HER3-DXd), a HER3 directed ADC, ifinatamab deruxtecan (I-DXd), a B7-H3 directed ADC, and raludotatug deruxtecan (R-DXd), a CDH6 directed ADC, are being jointly developed and commercialized globally with Merck & Co., Inc., Rahway, NJ. U.S.A. DS-3939, a TA-MUC1 directed ADC, is being developed by Daiichi Sankyo.

Designed using Daiichi Sankyo’s proprietary DXd ADC technology to target and deliver a cytotoxic payload inside cancer cells that express a specific cell surface antigen, each ADC consists of a monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

Datopotamab deruxtecan, ifinatamab deruxtecan, patritumab deruxtecan, raludotatug deruxtecan and DS-3939 are investigational medicines that have not been approved for any indication in any country. Safety and efficacy have not been established.
