Leqembi, developed by Biogen and Eisai, is a monoclonal antibody that moderately slows cognitive decline in early-stage Alzheimer's patients, offering them more functional time.
The rollout of Leqembi faces challenges, including reimbursement uncertainties, diagnostic test requirements, and limited availability of neurologists and specialized infusion centers.
Despite the drug's potential benefits, it carries risks of brain swelling and bleeding, necessitating careful patient monitoring and adherence to strict eligibility criteria.
Eisai and Biogen are working on more convenient formulations of Leqembi, such as monthly infusions and subcutaneous injections, to ease the burden on patients and expand access.
