The FDA approves a new maintenance dosing regimen for lecanemab (Leqembi; Eisai) in patients with early-stage Alzheimer disease (AD), enabling a transition from biweekly to once-every-4-week dosing while preserving clinical and biomarker benefits.

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.

Biogen BIIB announced that the FDA has approved a monthly maintenance dosing version for its intravenously (IV) administered Alzheimer's disease (AD) drug, Leqembi. Post the FDA approval, patients have the option to transition to a monthly maintenance dosing regimen of Leqembi after completing an 18-month course of biweekly infusions of the drug.
