Just months after the controversial FDA approval of Alzheimer’s disease drug Aduhelm (aducanumab), partners on that medicine, Eisai Co. Ltd. and Biogen Inc., are advancing a BLA for another possible AD therapy, lecanemab. Formerly known as BAN-2401, the Bioarctic AB-originated antibody is designed to neutralize and eliminate soluble, toxic amyloid beta for the treatment of early AD. The rolling submission, in pursuit of an accelerated approval, was primarily based on data from a phase IIb trial in people with early AD and confirmed amyloid pathology.
