Fact checked by Nick Blackmer The Food and Drug Administration (FDA) has approved a new maintenance dosing schedule for Leqembi, a monoclonal antibody treatment shown to slow cognitive decline in people with early Alzheimer’s disease.

A monthly 10 mg/mL maintenance dose of Leqembi had the same effects on mild Alzheimer’s symptoms as biweekly dose, research shows.

The US Food and Drug Administration has approved the supplemental biologics licence application (sBLA) of Eisai and Biogen's Leqembi (lecanemab-irmb) for maintenance dosing once every four weeks for the early stages of Alzheimer's disease.

The U.S. Food and Drug Administration has approved monthly maintenance dosing for Japan's Eisai and partner Biogen's Alzheimer's drug Leqembi, the companies said on Monday.

The monthly maintenance regimen, which offers a more convenient frequency than the initially approved treatment schedule for patients with Alzheimer’s, could help with Leqembi’s thus far disappointing uptake and sales.

Approval was based on results from multiple studies, which demonstrated a slowing of cognitive decline in patients with Alzheimer disease administered Leqembi.
