What's Happening?
Daiichi Sankyo is showcasing new clinical research at the 2025 European Society for Medical Oncology Congress, highlighting advances in breast cancer treatment. The company is presenting data from its DXd antibody drug conjugate portfolio, including ENHERTU and DATROWAY, which have shown potential to transform standards of care for patients with breast cancer. The DESTINY-Breast11 and DESTINY-Breast05 trials demonstrate ENHERTU's potential as a foundational treatment in curative-intent settings for HER2 positive early breast cancer. Additionally, DATROWAY has shown significant improvement in overall survival compared to chemotherapy for patients with metastatic triple negative breast cancer.
Why It's Important?
The data presented by Daiichi Sankyo at ESMO underscores the potential of its DXd ADC portfolio to significantly impact breast cancer treatment. ENHERTU's ability to become a foundational treatment in early breast cancer settings could improve patient outcomes and expand treatment options. DATROWAY's success in improving survival rates for triple negative breast cancer patients represents a breakthrough in a challenging area of oncology. These advancements may lead to new standards of care, offering hope to patients with limited treatment options and potentially reducing mortality rates associated with breast cancer.
What's Next?
Daiichi Sankyo plans to continue expanding its DXd ADC portfolio to address unmet needs in cancer treatment. The company is conducting several trials-in-progress, including the DESTINY-Endometrial01 phase 3 trial and the REJOICE-GI01 trial, to further explore the efficacy of its ADCs in various cancer types. Regulatory submissions seeking tumor agnostic approval for ENHERTU are under review in the EU and Japan. Daiichi Sankyo's ongoing research and development efforts aim to establish new standards of care across multiple cancer types, potentially leading to more effective and personalized treatment options.
