FDA Approves Monthly Dosing for Alzheimer’s Drug Leqembi

In a significant development for Alzheimer’s treatment, the U.S. Food and Drug Administration (FDA) has authorized a monthly maintenance dosing option for Eisai and Biogen’s Alzheimer’s drug, Leqembi. Originally requiring bi-weekly infusions, this alteration in administration could streamline treatment processes, making it more accessible to patients and healthcare providers.

Leqembi, which obtained FDA approval in 2023, addresses cognitive decline in Alzheimer’s patients by targeting and clearing amyloid-beta protein deposits in the brain, a known hallmark of the disease. Despite its clinical benefits, the bi-weekly intravenous administration, coupled with necessary MRI scans for safety, posed logistical challenges. The new monthly dosing regimen comes after 18 months of traditional bi-weekly treatment, easing the burden on patients and healthcare systems.

The market for Alzheimer’s therapies is competitive, with drugs like Ely Lilly’s Kisunla offering once-monthly infusions as well. Leqembi and Kisunla both carry safety warnings for potential brain swelling and bleeds, necessitating consistent monitoring via scans. These advancements in dosing regimens underline a growing focus on enhancing patient convenience and improving healthcare efficiency.

The FDA’s approval of monthly dosing for Leqembi represents a pivotal shift in Alzheimer’s treatment, potentially improving patient compliance and accessibility. As Eisai and Biogen pave the way for more patient-friendly options, the industry stays keen on innovations that merge clinical efficacy with practical ease.
