The DYNASTY-Breast02 study is a Phase 3 clinical trial aimed at evaluating the efficacy and safety of DB-1303/BNT323 compared to investigator’s choice chemotherapy in patients with HER2-low, hormone receptor-positive metastatic breast cancer. The study targets patients whose disease has progressed on endocrine therapy. This trial is significant as it could offer a new treatment option for a challenging patient population.
The intervention being tested is DB-1303/BNT323, an experimental drug administered intravenously. It is compared against standard chemotherapy options like capecitabine, paclitaxel, and nab-paclitaxel, which are currently used in similar patient settings.
The study follows a randomized, parallel assignment design without masking, focusing primarily on treatment efficacy. Participants are randomly allocated to receive either the experimental drug or one of the standard chemotherapy options.
The study began on January 18, 2024, with an estimated primary completion date in 2025. The latest update was submitted on July 16, 2025. These dates are crucial as they indicate the study’s progress and potential timeline for results.
The market implications of this study are significant for BioNTech SE and its collaborator DualityBio Inc. A positive outcome could enhance their market position and influence investor sentiment positively. The study’s results could also impact the competitive landscape in the oncology sector, particularly for companies focusing on breast cancer therapies.
The DYNASTY-Breast02 study is currently ongoing, with further details available on the ClinicalTrials portal.
