Eisai (OTCPK:ESAIY), the Japan-based partner of Biogen (NASDAQ:BIIB), estimated on Friday that the companiesâ newly approved Alzheimerâs therapy Leqembi (lecanemab) will generate $7.4B (1T Yen) in worldwide sales in 2030.
After the FDA greenlighted the anti-amyloid monoclonal antibody under the agencyâs accelerated approval for early Alzheimerâs disease, the companies launched the treatment in January at a wholesale acquisition cost of $26.5K per year.

While Medicare has restricted its use so far for those in clinical studies, Eisaiâs (OTCPK:ESALF) forecast assumes broader coverage in the U.S.
The company also expects about 2.5M people globally will be eligible to receive the infusion in 2030, with prevalence in Asia/Latin America and China making up 70% of total cases.
In March, the FDA accepted the companyâs marketing application for Leqembi to convert the accelerated approval into formal approval under the agency's priority review, granting July 6, 2023, as the target action date.
