Panel Backs Full Approval of Alzheimer’s Drug
FDA’s Peripheral and Central Nervous Systems Drugs Advisory Committee 6/9 voted 6 to 0 that data from the Phase 3 CLARITY AD trial verified the clinical benefit of Eisai/Biogen’s Leqembi (lecanemab) in the early treatment of Alzheimer’s disease. Eisai received accelerated approval for Leqembi 1/6 and was required to conduct a postmarketing clinical trial verifying and describing the anticipated Leqembi clinical benefit. The primary safety issues identified in the study are amyloid-related imaging abnormalities, cerebral hemorrhage, and infusion-related reactions and hypersensitivity.
Panel members agreed that the study met its primary endpoint and also showed significant treatment effects in secondary endpoints. In voting yes, panel acting chair and University of Arizona College of Medicine professor Robert C. Alexander said lecanemab’s overall benefit-risk assessment was favorable. “There are adverse events associated with the candidate treatment, some of them can be quite serious, but they're monitorable.”
FDA has set a 7/6 user fee review action target date to render a final decision on whether to grant full approval, which would trigger Medicare coverage almost immediately. Coverage was not available under accelerated approval (see earlier story).
