July 06, 2023 -- Today, 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. Leqembi was approved in January under the Accelerated Approval pathway.

LEQEMBI’s traditional approval is based on Phase 3 data from Eisai’s large, global Clarity AD clinical trial, in which LEQEMBI met its primary endpoint and all key secondary endpoints with statistically significant results and confirmed the clinical benefit of LEQEMBI. The primary endpoint was the global cognitive and functional scale, Clinical Dementia Rating Sum of Boxes (CDR-SB). LEQEMBI treatment reduced clinical decline on CDR-SB by 27% at 18 months compared to placebo.

“Today, the FDA approved LEQEMBI under the traditional approval pathway, making LEQEMBI the first and only approved anti-amyloid Alzheimer's disease treatment shown to reduce the rate of disease progression and to slow cognitive impairment in the early and mild dementia stages of the disease.” said Haruo Naito, Chief Executive Officer at Eisai.
