AstraZeneca's Datroway Wins EU Regulator's Recommendation as First-Line Breast Cancer Treatment
Positive for
The European Medicines Agency's Committee for Medicinal Products for Human Use has recommended AstraZeneca's Datroway for approval in the EU as a first-line treatment, marking a significant regulatory milestone that expands the drug's addressable patient population.
The European Medicines Agency's CHMP has issued a positive recommendation for AstraZeneca's Datroway (datopotamab deruxtecan), endorsing its approval in the European Union as a first-line treatment. The CHMP recommendation is the penultimate step before European Commission formal approval, which typically follows within two months of the committee's positive opinion.
Datroway is an antibody-drug conjugate developed jointly by AstraZeneca and Daiichi Sankyo, targeting a protein expressed on cancer cells. Its potential approval as a first-line therapy -- meaning it can be used at the start of treatment rather than after other treatments have failed -- significantly expands the commercial opportunity compared with a second- or later-line indication. First-line approvals typically reach more patients and generate higher peak sales.
The recommendation follows Datroway's earlier development in the same oncology pipeline that produced Enhertu (trastuzumab deruxtecan), AstraZeneca's flagship cancer drug which has already received multiple approvals across cancer types including breast and lung. Datroway addresses a different receptor target, giving AstraZeneca a broader ADC (antibody-drug conjugate) portfolio spanning multiple cancer treatment pathways.
For AstraZeneca's commercial trajectory, a first-line EU approval for Datroway adds to the pipeline of recently approved or near-approved oncology assets that are expected to drive revenue growth over the next several years. Analysts have identified AstraZeneca's oncology portfolio expansion as the primary driver of the group's medium-term revenue forecasts.

Frequently asked questions
What is the difference between Datroway and Enhertu -- are they the same drug?
Datroway (datopotamab deruxtecan) and Enhertu (trastuzumab deruxtecan) are different antibody-drug conjugates (ADCs) developed by AstraZeneca and Daiichi Sankyo. Both use the same DXd toxin payload and linker technology but carry different antibodies that target different proteins on cancer cells. Enhertu targets HER2, while Datroway targets TROP2. They address overlapping but distinct patient populations and cancer indications.
