Breaking: Biontech Launches Phase 3 Study for Innovative Breast Cancer Therapy – Hope for Her2-Low Tumors
June 10, 2025 – Biontech has launched a Phase 3 study for a groundbreaking new breast cancer drug, sparking hope for patients suffering from Her2-low tumors. This development could revolutionize the treatment landscape for metastatic breast cancer, which has traditionally had limited therapeutic options.
Innovative Therapy with BNT323/DB-1303
BNT323/DB-1303 is an antibody-drug conjugate developed in partnership between Biontech and DualityBio. The drug is designed to target HR+ and Her2-low metastatic breast cancer by combining the precision of antibodies with the potent cell-killing effects of chemotherapy. This innovative approach seeks to deliver chemotherapeutics directly into cancer cells, minimizing side effects and enhancing efficacy.
Encouraging Phase 1/2 Study Results
The move to Phase 3 comes on the heels of promising results from the Phase 1/2 study, which showed an objective response rate of 38.5% and a disease control rate of 84.6% in Her2-low breast cancer patients. These results were presented at the ASCO Congress 2023 and indicate a robust mechanism of action and a controllable safety profile.
Global Phase 3 Study: DYNASTY-Breast02
The Phase 3 study, titled DYNASTY-Breast02, aims to enroll 532 patients worldwide across 223 study centers. Starting in China, the trial will also involve locations in the USA, Europe, and other regions. The study will assess the effectiveness and safety of BNT323/DB-1303 compared to standard chemotherapy regimens, focusing on progression-free survival as the primary endpoint.
Breast Cancer Facts and Statistics
Breast cancer is the most common cancer worldwide and the leading cause of cancer in women. In Germany, about 74,500 women and 690 men were diagnosed in 2022. While survival rates have improved significantly, advanced metastatic breast cancer remains challenging to treat. Early detection through mammography screening and regular self-examinations can vastly improve outcomes.
The Importance of Early Detection
Key symptoms to watch for include lumps, changes in breast size or shape, and unusual nipple discharge. Regular check-ups and participation in early detection programs can save lives. Patients with Her2-low tumors now have more cause for optimism as this innovative therapy aims to fill a significant therapeutic gap.
