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.
