Daiichi Sankyo Highlights Progress Across Oncology Portfolio in Multiple Solid and Blood Cancers at ESMO Asia, SABCS and ASH
- Three late-breaking presentations across lung and breast cancer trials of three DXd ADCs to be showcased
- Science & Technology Day to provide overview of data and 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 with more than 45 abstracts in multiple types of solid and blood cancers at the 2024 ESMO Asia Congress (#ESMOAsia24), San Antonio Breast Cancer Symposium (#SABCS24) and American Society of Hematology (#ASH24) Annual Meeting prior to its Science & Technology Day.
Data at ESMO Asia, SABCS and ASH will showcase Daiichi Sankyo’s progress towards its goal of creating new standards of care for patients with cancer. Highlights include three late-breaking presentations, including a pooled analysis of data from the TROPION-Lung05 phase 2 and TROPION-Lung01 phase 3 trials of datopotamab deruxtecan (Dato-DXd) in patients with EGFR-mutated advanced non-small cell lung cancer (NSCLC) at ESMO Asia, as well as a subgroup analysis from the DESTINY-Breast06 phase 3 trial of ENHERTU® (trastuzumab deruxtecan) in patients with unresectable or metastatic HR positive, HER2 low (IHC 1+ or IHC 2+/ISH-) or HER2 ultralow (IHC 0 with membrane staining) breast cancer and the primary analysis from the VALENTINE phase 2 trial of patritumab deruxtecan (HER3-DXd) in patients with early HR positive, HER2 negative breast cancer at SABCS.
“Important updates in difficult-to-treat cancers including lung, breast, gastric and biliary tract cancer as well as acute myeloid leukemia and peripheral T-cell lymphoma will be highlighted at these upcoming meetings,” said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. “We continue to make important progress with our approved and pipeline medicines with the goal of changing the standard of care across a wide range of cancers.”
Innovation in Lung, Breast, Gastric and Biliary Tract Cancer at ESMO Asia Late-breaking data at ESMO Asia will highlight a pooled analysis of results from the TROPION-Lung05 phase 2 and TROPION-Lung01 phase 3 trials of datopotamab deruxtecan in patients with previously treated EGFR-mutated advanced NSCLC during a proffered paper session.
Two mini oral presentations will feature results of the TROPION-Breast01 phase 3 trial of datopotamab deruxtecan in Chinese patients with previously treated metastatic HR positive, HER2 low or negative breast cancer and the final results of the DESTINY-Gastric06 phase 2 trial of ENHERTU in Chinese patients with previously treated HER2 positive advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma. Results of DESTINY-Gastric06 led to the recent conditional approval in China of ENHERTU as a monotherapy for the treatment of adult patients with locally advanced or metastatic HER2 positive gastric or GEJ adenocarcinoma who have received two or more prior treatment regimens.
Trials-in-progress posters also will feature the trial designs of three ongoing ENHERTU clinical trials, including the DESTINY-BTC01 phase 3 trial that will evaluate ENHERTU with rilvegostomig, AstraZeneca’s PD-1/TIGIT bispecific antibody, versus standard of care in patients with previously untreated HER2 expressing, locally advanced or metastatic biliary tract cancer, and the DESTINY-Gastric03 phase 1b/2 trial where a new arm has been added to evaluate ENHERTU in combination with rilvegostomig and chemotherapy in patients with HER2 positive or HER2 low gastric or GEJ adenocarcinoma. A second part of the DESTINY-PanTumor02 phase 2 trial of ENHERTU also will be presented where patients with previously treated HER2 expressing metastatic solid tumors will be enrolled into one of five new cohorts: patients with any tumor expressing HER2 IHC 3+ (excluding breast, gastric and colorectal cancer); patients with any tumor expressing HER2 IHC 2+/ISH+ (excluding breast, gastric and colorectal cancer); patients with HER2 IHC 2+/1+ endometrial cancer; patients with HER2 IHC 2+/1+ ovarian cancer; and patients with HER2 IHC 2+/1+ cervical cancer.
Continued Progress in Breast Cancer at SABCS Late-breaking presentations in breast cancer at SABCS will include two oral presentations featuring a subgroup analysis of the DESTINY-Breast06 phase 3 trial reporting on the impact of response to prior endocrine-based therapy on outcomes in patients with unresectable or metastatic HR positive, HER2 low or HER2 ultralow breast cancer who failed at least one line of endocrine therapy receiving ENHERTU compared to chemotherapy, and the primary results from the VALENTINE phase 2 trial evaluating neoadjuvant patritumab deruxtecan (HER3-DXd) alone or in combination with letrozole in patients with high-risk HR positive, HER2 negative early breast cancer.
Other data at SABCS includes two spotlight poster presentations highlighting the first exploratory biomarker analysis assessing the impact of genomic alterations on the efficacy of ENHERTU compared to ado-trastuzumab emtansine (T-DM1) in patients with HER2 positive metastatic breast cancer from the DESTINY-Breast03 phase 3 trial, and the effects of ENHERTU on health-related quality of life and neurological function from the DESTINY-Breast12 phase 3b/4 trial in patients with previously treated HER2 positive metastatic breast cancer with or without brain metastases. Final results from the dose expansion portion of the DESTINY-Breast08 phase 1b trial evaluating ENHERTU in combination with capecitabine or capivasertib in patients with HER2 low metastatic breast cancer also will be presented as a poster presentation.
Trial-in-progress posters will feature the trial designs from a sub-protocol of a phase 1b master protocol trial evaluating ENHERTU in combination with valemetostat, a dual EZH1 and EZH2 inhibitor, in patients with previously treated HER2 low unresectable or metastatic breast cancer as well as a phase 1b trial evaluating the combination in patients with previously treated HER2 low, HER2 ultralow or HER2 null metastatic breast cancer.
Updates in Hematology Portfolio in Certain Leukemias and Lymphomas At ASH, several sub-analyses of the QuANTUM-First phase 3 trial of VANFLYTA® (quizartinib) in patients with newly diagnosed FLT3-ITD positive acute myeloid leukemia (AML) will be presented. An oral presentation will highlight data on the frequency of co-mutations in trial patients and their impact on remission rate, overall survival and relapse-free survival. Three poster presentations will report new data, including the impact of continuation therapy on the efficacy of VANFLYTA, focusing on measurable residual disease status; a concordance between utilizing a FLT3-ITD mutation detection clinical trial assay and a next-generation sequencing measurable residual disease assay; and a matching adjusted indirect comparison analysis of VANFLYTA compared to midostaurin in patients with newly diagnosed FLT3-ITD AML.
Additionally, several poster presentations will report on the QUIWI phase 2 trial that evaluated VANFLYTA in combination with standard chemotherapy in patients with newly diagnosed FLT3-ITD negative AML, including the final results of QUIWI and sub-analyses of the trial by mutational status, including FLT3-TKD and NPM1, and ELN risk categorization. The QUIWI phase 2 trial formed the basis of the QuANTUM-Wild phase 3 trial that is further evaluating the addition of VANFLYTA to standard chemotherapy in this patient population. The design of the QuANTUM-Wild phase 3 trial will be highlighted as a trial-in-progress poster.
Other data at ASH includes two poster presentations reporting the primary results of the VALYM phase 2 trial of valemetostat in patients with relapsed or refractory large B-cell lymphoma and an exploratory analysis of circulating tumor DNA, a novel biomarker, to potentially predict clinical response to valemetostat from the VALENTINE-PTCL01 phase 2 trial in patients with relapsed or refractory peripheral T-cell lymphoma, which was recently published in The Lancet Oncology.

About the ADC Portfolio of Daiichi Sankyo The Daiichi Sankyo ADC portfolio consists of seven ADCs in clinical development crafted from two distinct ADC technology platforms discovered in-house by Daiichi Sankyo.
The ADC platform furthest in clinical development is Daiichi Sankyo’s DXd ADC Technology where 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. The DXd ADC portfolio currently consists of ENHERTU, a HER2 directed ADC, and datopotamab deruxtecan (Dato-DXd), a TROP2 directed ADC, which 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, USA. DS-3939, a TA-MUC1 directed ADC, is being developed by Daiichi Sankyo.
The second Daiichi Sankyo ADC platform consists of a monoclonal antibody attached to a modified pyrrolobenzodiazepine (PBD) payload. DS-9606, a CLDN6 directed PBD ADC, is the first of several planned ADCs in clinical development utilizing this platform.
Datopotamab deruxtecan, ifinatamab deruxtecan, patritumab deruxtecan, raludotatug deruxtecan, DS-3939 and DS-9606 are investigational medicines that have not been approved for any indication in any country. Safety and efficacy have not been established.
