With the tumultuous rollout of Aduhelm behind them, partners Biogen and Eisai have the rare opportunity for a do-over, with all-important data on their next Alzheimer’s disease therapy expected next month.
By the end of September, the world will learn whether lecanemab, another treatment aimed at toxic brain plaques called amyloid, can significantly slow the cognitive decline that characterizes Alzheimer’s.
The outcome is vitally important for millions of patients awaiting a medicine that can meaningfully impact the disease, and success could spell a massive financial windfall for Biogen and Eisai. Failure would damage — though not destroy — the idea that targeting amyloid might ever make for an efficacious treatment.
