The European Medicines Agency has issued a negative opinion for Leqembi (lecanemab), a treatment for Alzheimer’s disease, saying that the benefits of the drug do not outweigh the risks. The opinion, issued on 25 July, is in contrast to decisions by regulatory authorities in six other countries, including the US, which have all approved the treatment. Leqembi is currently being marketed in the US, Japan and China. Co-developer Eisai Co Ltd said that it will appeal against the decision.
