Two favorable EU opinions for AstraZeneca
The European Medicines Agency's CHMP recommended approval of AstraZeneca's Enhertu for early breast cancer treatment, potentially making it a new standard of care. The drug generated $1.8bn in 2025 revenue. The EMA also recommended approval for Klygefa, another AstraZeneca medicine. AstraZeneca shares were down 0.7% Monday, despite a 2.4% gain on Friday following the announcements.
