Eisai's LEQEMBI Receives FDA Nod for Subcutaneous Alzheimer’s Therapy

FDA Acceptance for LEQEMBI's Subcutaneous Maintenance Dosing

LEQEMBI stands at the forefront as the only FDA-approved anti-amyloid therapy tailored for early Alzheimer’s disease, promising the convenience of subcutaneous injections at home.

Eisai Co., Ltd. and Biogen Inc. have shared significant news regarding the U.S. Food and Drug Administration (FDA)'s acceptance of the Biologics License Application (BLA) for LEQEMBI, which contains lecanemab-irmb. This acceptance paves the way for subcutaneous autoinjector options aimed at weekly maintenance dosing, which is essential for the treatment of Alzheimer's disease (AD) in patients showing Mild Cognitive Impairment (MCI) or mild dementia.

Understanding the Importance of the Approval

This BLA builds upon robust data gathered throughout the Clarity AD clinical study—an open-label extension. If approved, LEQEMBI would be the sole Alzheimer's treatment allowing for subcutaneous administration via an auto-injector, a method that could potentially revolutionize the patient experience for those undergoing AD treatments.

The simplicity of the injection process, averaging just 15 seconds, enhances the treatment experience for patients who have already transitioned from the biweekly intravenous (IV) phase. The regimen comprises administering a 360 mg weekly dose, intended to sustain the clinical and biomarker benefits achieved previously.

Significance of Early Treatment for Alzheimer’s Disease

Alzheimer's is a relentless and progressive ailment that evolves due to an underlying neurotoxic process that intensifies over time. LEQEMBI is designed to combat this advancement through an innovative dual-action approach—continuously clearing damaging protofibrils and rapidly reducing plaque levels. Its continuous usage is crucial since the toxic protofibrils can inflict neuronal damage even post plaque clearance.

Long-term data presented at a prestigious Alzheimer’s conference suggested that initiating treatment early may provide sustained therapeutic benefits that endure long after plaque clearance. This finding emphasizes the urgent need for effective early interventions in Alzheimer’s cases.

Patient Convenience and Treatment Accessibility

The new autoinjector is anticipated to simplify both usage for patients and care partners, potentially diminishing the frequency of hospital or infusion site visits. With at-home administration, patient adherence is expected to improve significantly, streamlining the pathway to ongoing treatment.

Currently, LEQEMBI is approved in several countries, including the U.S., Japan, South Korea, China, and the UAE. Additionally, recent endorsements from the European Medicines Agency are indicators of its growing recognition and acceptance as a vital treatment for Alzheimer’s disease.

Collaboration between Eisai and Biogen

Eisai undertakes the lead role in the global development of lecanemab, with regulatory submissions conducted in partnership with Biogen. The collaboration, established in 2014, has focused on advancing Alzheimer's disease therapies, ensuring that both companies benefit from the expertise and resources that they bring to the project.

Future Prospects and Ongoing Research

Eisai and Biogen continue to push forward with new avenues of research, including ongoing studies about patients with preclinical Alzheimer's that reflect their commitment to enhancing treatment options. Over the years, the exploration of lecanemab has deepened our understanding of Alzheimer’s therapies, positioning it as a potentially transformational player in the medical landscape.
