Eisai and Biogen Celebrate FDA's Approval for Leqembi's Monthly Dosing
FDA Approves Monthly Maintenance Dosing of Leqembi
In a significant development for Alzheimer's treatment, the U.S. Food and Drug Administration (FDA) has greenlit the monthly maintenance dosing for Leqembi, an Alzheimer's drug developed by Japan's Eisai and its partner Biogen (NASDAQ: BIIB). This approval marks a pivotal moment as it allows patients easier access to crucial therapy.
Advantages of Monthly Maintenance Dosing
The approval for the monthly regimen came after the drug initially received its standard U.S. approval in 2023, following evidence that it effectively slows cognitive decline associated with Alzheimer's. Despite this positive news, growth in the drug's uptake has been gradual. The slower growth is attributed to the complexity of the initial treatment protocol, which requires patients to undergo time-consuming infusions every two weeks as well as regular MRIs and screenings.
With the new maintenance protocol, patients who have received Leqembi via intravenous infusion for 18 months can transition to a once-a-month dose. This change is expected to improve the overall convenience for patients and possibly enhance ongoing adherence to treatment.
How Leqembi Works in Treating Alzheimer's
Leqembi operates by removing amyloid beta protein deposits in the brain. These sticky substances are indicative of Alzheimer's disease and believed to contribute to the cognitive decline seen in patients. During treatment, patients receive Leqembi at an infusion center, where the process typically lasts nearly an hour.
The success of maintenance dosing has been supported by modeling simulations of trial data, which suggest that this less frequent dosing schedule will retain the therapeutic benefits that patients experience.
Comparison with Competing Alzheimer's Treatments
In the competitive landscape of Alzheimer's medications, Eisai and Biogen are not alone. Eli Lilly (NYSE: LLY) has also released its drug, Kisunla, which received approval in July and is administered via infusion once a month. In contrast, patients receiving Kisunla can discontinue treatment when brain scans no longer detect amyloid plaques.
Both Leqembi and Kisunla have safety advisories, particularly concerning the risks of brain swelling and bleeding, necessitating monitoring through imaging scans during treatment.
Collaboration and Future Prospects
Eisai's strategic collaboration with BioArctic underlines the ongoing commitment to advancing treatment options for Alzheimer's patients. The implications of this FDA approval could make a significant impact on patient management and encourage further research and development in this critical area of medical need.
