In a recent regulatory decision, the European Medicines Agency (EMA) has denied approval for Eli Lilly’s experimental Alzheimer’s treatment, Donanemab, marketed under the brand name Kisunla. This setback stems from the EMA’s concerns regarding the drug’s safety profile, particularly its association with severe side effects such as brain swelling (amyloid-related imaging abnormalities or ARIA) and bleeding.
Donanemab, a monoclonal antibody targeting amyloid plaques in the brain, has already received approvals in the U.S., Japan and China, where it was heralded as a potential breakthrough for patients with early-stage Alzheimer’s. However, after reviewing clinical trial data, European regulators determined that the potential risks might outweigh the therapeutic benefits.
The EMA’s decision reflects ongoing caution surrounding amyloid-targeting therapies, which have faced scrutiny due to their safety risks, despite showing modest efficacy in slowing cognitive decline.
Eli Lilly, expressing disappointment with the outcome, stated that it plans to continue discussions with the EMA in hopes of addressing their concerns and seeking a path toward future approval. The company remains committed to providing innovative treatments for Alzheimer’s, a devastating disease that affects millions worldwide. This development underscores the challenges of navigating regulatory hurdles for Alzheimer’s therapies, even amid growing demand for effective treatments.
While donanemab has offered hope to many patients and caregivers, the EMA’s rejection serves as a reminder of the delicate balance between efficacy and safety in the approval process. For now, Alzheimer’s patients and advocates in Europe will need to wait for further updates as Eli Lilly works to address the EMA’s reservations and potentially revisit the application in the future.
