"Biogen Halts Production of Aduhelm, Shifts Focus to Experimental Treatments"

Biogen announced it will discontinue the development and marketing of Aduhelm, a controversial Alzheimer's drug that received accelerated approval from the FDA in 2021. The decision comes after an internal review led the company to redirect its resources toward other drug candidates and advancing Leqembi, another Alzheimer’s drug it’s marketing with Eisai. The clinical trials for Aduhelm and Leqembi showed modest benefits for patients and potentially dangerous side effects, leading to limited Medicare coverage for Alzheimer’s drugs with accelerated approval.
