- Eisai's Submission to FDA: Eisai has submitted an sBLA to the U.S. FDA for a monthly maintenance dose of Alzheimer's therapy Leqembi, aiming to transition patients from an intravenous infusion every two weeks to a monthly maintenance phase.
- Fast Track Designation: Eisai planned a rolling BLA for a subcutaneous version of Leqembi but was asked by the FDA to seek a separate Fast Track designation specific to the SC formulation, delaying the process.
- Future Steps: Eisai requested Fast Track designation for the SC formulation in March and will start a rolling submission upon approval, expected within 60 days from the submission date.
- Biogen Involvement: The therapy is marketed with Biogen, and recent events include Biogen Inc.'s participation in conferences and EU's delay in deciding on the Alzheimer's drug co-developed by Eisai and Biogen.
- Personnel Changes: Biogen's chief medical officer has left the company to join Alto Neuroscience board, indicating shifts in leadership within the organizations involved in the Alzheimer's therapy development.
