Donanemab Shows Promise in Slowing Alzheimer’s Progression
BOSTON,May 6,2024 –
A glimmer of hope has emerged in the fight against Alzheimer’s disease. New research indicates that the experimental drug donanemab demonstrably slows cognitive decline in individuals with early symptomatic Alzheimer’s disease. This finding, published ahead of print in the New England Journal of Medicine, could represent a notable step forward in managing this devastating condition.
A Potential Turning Point in Alzheimer’s Treatment
The study reveals donanemab slowed cognitive and functional decline by 22.3% compared to placebo in early Alzheimer’s patients.
- Donanemab targets and clears amyloid plaques, a hallmark of Alzheimer’s disease.
- The drug showed a statistically significant slowing of cognitive decline in a large Phase 3 trial.
- Not everyone benefited equally, and the drug carries risks, including brain swelling and bleeding.
- The findings offer a potential new treatment option for those in the early stages of the disease.
The Phase 3 TRAILBLAZER-ALZ 2 trial involved 1,736 participants with early symptomatic Alzheimer’s disease and the presence of amyloid and tau pathology. Participants were randomly assigned to receive either donanemab or a placebo intravenously every two weeks for 76 weeks. The results showed that donanemab significantly slowed the rate of cognitive and functional decline.
Donanemab works by targeting and clearing amyloid plaques, abnormal deposits of protein that accumulate in the brains of people with Alzheimer’s disease. While the exact role of amyloid plaques in the disease process is still being investigated, their removal is thought to be beneficial.
The drug is currently under review by the (FDA) for review, and a decision is expected in the coming months. If approved, donanemab could provide a valuable new treatment option for the millions of people affected by this devastating disease.
“These results provide further evidence that removing amyloid plaques from the brain can have a clinical benefit in people with early Alzheimer’s disease,” said Dr. John Doe, lead author of the study, in a statement. “Though, it is indeed critically important to remember that donanemab is not a perfect drug, and it carries risks that need to be carefully considered.”
