1. FDA grants full approval to Alzheimer's drug Leqembi

The Food and Drug Administration on Thursday gave full approval to Leqembi, a drug that can slow the progression of Alzheimer's disease. While other drugs have been approved that target the symptoms of Alzheimer's, this is the first time the FDA has granted full regulatory approval to one meant to slow cognitive decline. Leqembi, made by the drugmakers Eisai and Biogen, targets beta-amyloid, a kind of protein in the brain believed to play a role in Alzheimer's disease. For the phase 3 clinical trial of the drug, 1,795 people with mild cognitive impairment or early-stage Alzheimer's participated, and researchers found that over 18 months, progression of the disease slowed by 27%. This is not a cure, but "it's a first step for hopefully more therapeutics in the future," Dr. Ronald Peterson, a neurologist at the Mayo Clinic, told NBC News. Leqembi could cause serious side effects, including brain swelling and hemorrhage, and the drug will come with a boxed warning.
