The European Union's drugs regulator reversed its decision to block the Alzheimer's drug lecanemab, a treatment aimed at slowing cognitive decline in patients. In July, the Amsterdam-based European Medicines Agency (EMA) denied recommending approval of the drug made by Eisai and Biogen because it considered the risks - especially bleeding and swelling in the brain - to be greater than the potential benefits in a broad population.
