Next-gen Alzheimer’s drugs extend independent living by months

In the past two years, the Food and Drug Administration has approved two novel Alzheimer’s therapies, based on data from clinical trials showing that both drugs slowed the progression of the disease. But while the approvals of lecanemab and donanemab, both antibody therapies that clear plaque-causing amyloid proteins from the brain, were greeted with enthusiasm by some Alzheimer’s researchers, the response of patients has been muted. According to physicians who care for people with Alzheimer’s, many patients found it difficult to understand what the clinical trials results — presented as “percent decrease in the rate of cognitive decline” — meant for their own lives.
