Event Summary

The United States — Food and Drug Administration has extended the review period for Eisai's supplemental Biologics License Application (sBLA) for Lecanemab Iqlik, a once-weekly subcutaneous injection of lecanemab irmb for early Alzheimer's disease. The new Prescription Drug User Fee Act (PDUFA) action date is now August 24, 2026, a three-month extension from the previous May 24, 2026, date. This extension was due to the United States — Food and Drug Administration requesting additional information, which constituted a major amendment to the sBLA. Despite the delay, the United States — Food and Drug Administration has not raised concerns regarding the approvability of Lecanemab Iqlik as a starting dose. Lecanemab is a result of a collaboration between BioArctic and Eisai, with Eisai responsible for clinical development and commercialization.
