Blood test may replace brain scans for Alzheimer's drug monitoring

NCT ID NCT07153848

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study will follow 400 people with early Alzheimer's who are taking the drug lecanemab. Researchers want to see if simple blood tests can detect whether the drug is reducing amyloid plaques in the brain, which is currently measured with expensive PET scans. The goal is to find a cheaper, easier way to monitor treatment effectiveness.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

lecanemab

What this could lead to

If successful, this study could show that simple blood tests can track whether lecanemab is clearing amyloid plaques from the brain, potentially reducing the need for expensive PET scans.

What could go wrong

This is an observational study, not a controlled trial, so it cannot prove cause and effect. The results may not apply to all Alzheimer's patients, and blood biomarkers may not reliably match brain changes.
