The story of Aduhelm has been rocky now for years. Biogen turned heads when its controversial Alzheimer’s therapy won accelerated approval from the FDA against the advice of its own advisory panel in mid-2021. The company had high hopes for the antibody at that point, pricing it at an average of $56,000 per year. Aduhelm would encounter a series of blows after that – rejected coverage, dismal sales, discontinued trials. Biogen would ultimately pull the plug on the drug this year.
Now, Biogen aims to prioritize other Alzheimer’s programs like the lecanemab, which was jointly developed with Eisai and FDA-approved in July 2023. Biogen noted in a statement that insights gained from Aduhelm hold value for the company. Ultimately, Biogen recorded a $60 million charge tied to wrapping up Aduhelm’s development.
