FDA converts novel Alzheimer’s disease treatment to traditional approval

July 7, 2023
Action follows confirmatory trial to verify clinical benefit.

The U.S. Food and Drug Administration converted Leqembi (lecanemab-irmb), indicated to treat adult patients with Alzheimer’s Disease, to traditional approval following a determination that a confirmatory trial verified clinical benefit.

Leqembi is the first amyloid beta-directed antibody to be converted from an accelerated approval to a traditional approval for the treatment of Alzheimer’s disease. The drug works by reducing amyloid plaques that form in the brain, a defining pathophysiological feature of the disease.
