New PET tracer aims to spot Alzheimer's tau tangles

NCT ID NCT05542953

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This completed Phase 3 study tested whether a radioactive tracer called [18F]APN-1607 can help detect Alzheimer's disease by lighting up tau tangles in the brain during a PET scan. Researchers compared brain scans of 230 people with Alzheimer's, mild cognitive impairment, and healthy volunteers. The goal was to see if the tracer's pattern differs between groups, which could improve diagnosis.

What this could mean

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

Active substance

[18F]APN-1607 (a radioactive tracer for PET scans)

What this could lead to

If successful, this could lead to a better way to diagnose Alzheimer's disease earlier and more accurately using a brain scan.

What could go wrong

This is a diagnostic study, not a treatment. The tracer may not clearly distinguish between Alzheimer's and other dementias, and results may not change patient outcomes.
