What is NORLIQVA?
NORLIQVA (lecanemab) is a monoclonal antibody designed to target amyloid-beta protofibrils associated with Alzheimer’s disease. Approved by the FDA in January 2023, it is marketed under Biogen and Eisai’s partnership. The drug is administered intravenously, with a typical monthly dosing regime.
