Biogen, a leading pharmaceutical company, has announced its decision to discontinue the development of its Alzheimer’s drug, Aduhelm. Once hailed as a potential breakthrough in Alzheimer’s treatment, Aduhelm faced significant challenges shortly after its initial launch a few years ago.
Background: The Rise and Fall of Aduhelm
Aduhelm, initially viewed as a promising blockbuster drug, encountered obstacles soon after its introduction to the market. Despite receiving accelerated approval from the Food and Drug Administration (FDA) in 2021, the drug failed to meet expectations.
Recent Developments and Decision
In a recent announcement, Biogen revealed its plans to terminate ongoing studies required for full FDA approval of Aduhelm. Additionally, the company will cease all sales of the drug. Patients currently using Aduhelm obtained through commercial channels can continue their treatment until November. It’s estimated that approximately 2,500 individuals worldwide are using Aduhelm.
Shifting Focus to Alternative Treatments
With the discontinuation of Aduhelm, Biogen aims to redirect its focus towards other Alzheimer’s treatments. Notably, the company is collaborating with Japanese pharmaceutical firm Eisai to promote another Alzheimer’s drug, Leqembi, which has already received full FDA approval.
Leqembi: A New Hope in Alzheimer’s Treatment
Leqembi stands out as the first medication proven to moderately slow cognitive decline in Alzheimer’s patients. While its efficacy is modest, regulators have endorsed it for individuals experiencing mild dementia and early Alzheimer’s symptoms.
Challenges Faced by Aduhelm
Despite initial optimism, Aduhelm encountered several challenges. Priced at $56,000 annually, the drug faced reluctance from physicians due to insufficient evidence supporting its effectiveness in slowing Alzheimer’s progression. Moreover, insurance coverage was limited, and Medicare imposed strict eligibility criteria, further hindering its widespread adoption.

Financial Implications for Biogen
Initially projected to be a blockbuster drug, Aduhelm fell short of expectations, generating only modest revenue for Biogen. Consequently, the company scaled back its marketing efforts in 2022. Additionally, Biogen’s attempts to secure external financing or partnerships for Aduhelm were unsuccessful.
Conclusion: Biogen’s Strategic Shift
Biogen’s decision to discontinue Aduhelm reflects a strategic reevaluation of its research and development priorities. Considering the substantial investments required for additional studies and anticipated advancements in the field, Biogen opted to cease further development of Aduhelm. The company anticipates a charge of approximately $60 million in its fourth-quarter financials due to the discontinuation of the Aduhelm program.
In summary, while the discontinuation of Aduhelm marks the end of a chapter for Biogen, the company remains committed to advancing innovative treatments for Alzheimer’s disease and addressing the evolving needs of patients worldwide.
