Biogen, Eisai Request Approval of Aducanumab for Alzheimer’s in Japan
Biogen and Eisai are seeking approval of aducanumab (BIIB037) for the treatment of Alzheimer’s disease in Japan, the companies have announced.

The approval requests were based on clinical data from Phase 3 trials — EMERGE (NCT02484547) and ENGAGE (NCT02477800) — which tested aducanumab in people with early Alzheimer’s disease. The trials were discontinued after an independent monitoring committee determined that aducanumab was not likely to produce meaningful benefits. However, an analysis of an additional three months of data, which
