Can a new PET tracer reveal hidden tau in the brain?
NCT ID NCT06690983
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
Summary
This study tests whether a radioactive tracer called 18F-S16/T807 can help diagnose tau-related brain diseases. Tau is a protein that builds up abnormally in conditions like Alzheimer's and other neurodegenerative disorders. Researchers will give 500 adults a single injection of the tracer and then perform PET/CT or MRI scans to measure tau levels in the brain. The goal is to see if this imaging method can accurately detect and distinguish tau-related diseases.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-S16/T807, a radioactive tracer for PET/CT imaging
- What this could lead to
- If it works, this could improve diagnosis of tau-related brain diseases, helping doctors detect and monitor these conditions more accurately.
- What could go wrong
- This is an early diagnostic study, and the tracer may not reliably distinguish tau buildup from other brain changes. It also requires further validation before clinical use.
