Analysis · AZN · Life Sciences
AstraZeneca and Daiichi Sankyo's Datroway has won EU approval for first-line metastatic triple-negative breast cancer in patients who are not candidates for immunotherapy. The green light rests on the TROPION-Breast02 trial, which showed a 5.0-month improvement in median overall survival (23.7 vs. 18.7 months) and a 43% reduction in the risk of progression or death versus chemotherapy. This decision expands Datroway's EU label to a second breast cancer indication and cements its standing as the only TROP2-directed ADC with an overall survival benefit in this setting. Coming on the heels of US approval in May 2026, the milestone adds to a string of recent regulatory wins for AstraZeneca's oncology portfolio, helping to offset the recent Wainua trial failure.
