Can a new drug stop inherited Alzheimer's in its tracks?

NCT ID NCT06384573

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests lecanemab, an antibody that targets amyloid plaques in the brain, in 40 people who carry a gene mutation that causes early-onset Alzheimer's. Participants previously received another anti-amyloid drug and will now receive lecanemab to see if it can fully clear amyloid plaques and slow cognitive decline. The goal is to understand whether aggressive amyloid removal can delay or prevent the onset of dementia in this high-risk group.

What this could mean

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

Active substance

lecanemab (also called BAN2401), given as an intravenous infusion

What this could lead to

If successful, this could show that removing amyloid plaques delays or slows the progression of inherited Alzheimer's disease, offering a potential treatment for this rare form.

What could go wrong

This is a small, open-label study with no placebo group, so results may be less reliable. The drug may not fully remove plaques or meaningfully slow the disease, and side effects like brain swelling or bleeding are possible.
