Datroway Recommended for EU Approval
The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a positive opinion for Datroway (datopotamab deruxtecan) as a 1st-line monotherapy for adult patients with unresectable or metastatic triple-negative breast cancer (TNBC) who are not candidates for PD-1/PD-L1 inhibitor therapy.
-
Significant Survival Benefit Demonstrated
The recommendation is based on the TROPION-Breast02 Phase III trial, where Datroway showed a statistically significant and clinically meaningful 5.0-month improvement in median overall survival (23.7 months vs. 18.7 months) and reduced the risk of disease progression or death by 43% compared to chemotherapy.
-
Addresses High Unmet Medical Need
If approved, Datroway has the potential to be the first TROP2-directed antibody drug conjugate with a demonstrated overall survival benefit for this aggressive form of breast cancer in the EU, where treatment options are currently limited.
-
Follows US Approval
This EU recommendation follows the US FDA approval of Datroway in May 2026 for the same indication, further expanding the drug's global market reach.
Analysis · AZN · Life Sciences
The positive opinion from the CHMP for Datroway in 1st-line metastatic triple-negative breast cancer (TNBC) is a significant regulatory milestone. This recommendation, based on a 5.0-month improvement in overall survival, paves the way for market expansion into the European Union for a drug already approved in the US. TNBC is an aggressive cancer with limited treatment options, making this a crucial development for patients and a strong revenue driver for AstraZeneca's oncology portfolio.
