AstraZeneca and Daiichi Sankyo’s BLA for Dato-DXd accepted in the US for treatment of breast cancer

Application based on results from the TROPION-Breast01 Phase III trial

  • By IPP Bureau | April 02, 2024

AstraZeneca and Daiichi Sankyo’s Biologics License Application (BLA) for datopotamab deruxtecan (Dato-DXd) has been accepted in the US for the treatment of adult patients with unresectable or metastatic hormone receptor (HR)-positive, HER2-negative breast cancer who have received prior systemic therapy for unresectable or metastatic disease. The Prescription Drug User Fee Act date, the US Food and Drug Administration (FDA) action date for its regulatory decision, is during the first quarter of 2025.

The BLA is based on results from the pivotal TROPION-Breast01 Phase III trial in which datopotamab deruxtecan demonstrated a statistically significant and clinically meaningful improvement for the dual primary endpoint of progression-free survival (PFS) compared to investigator’s choice of chemotherapy in patients with unresectable or metastatic HR-positive, HER2-negative breast cancer previously treated with endocrine-based therapy and at least one systemic therapy.

Datopotamab deruxtecan is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed by AstraZeneca and Daiichi Sankyo.

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “Despite marked progress in the treatment of HR-positive, HER2-negative breast cancer, most patients with advanced disease develop endocrine resistance and face the prospect of one or several lines of chemotherapy. If approved, datopotamab deruxtecan has the potential to provide these patients an efficacious and better tolerated alternative to conventional chemotherapy.”

Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo, said: “The FDA’s acceptance of the BLA brings us closer to providing patients with previously treated HR-positive, HER2-negative breast cancer an alternative option to conventional chemotherapy earlier in the metastatic setting. Following our recently accepted application for advanced nonsquamous non-small cell lung cancer in the US, along with additional regulatory reviews underway in China, the EU, Japan and other regions, we are working swiftly to bring datopotamab deruxtecan as a potential new treatment option to patients around the world.”
