New PET tracer for brain imaging tested in humans for first time
NCT ID NCT03347331
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This early-phase study tested a new radioactive tracer called [18F]F13640 in 20 healthy volunteers. The tracer is designed to attach to specific receptors in the brain and be seen on a PET scan. The goal was to validate the imaging method and check how reproducible the results are, not to treat any disease.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
[18F]F13640 (a radioactive tracer for PET scans)
What this could lead to
If successful, this could provide a new way to image brain receptors, potentially aiding research into neurological conditions.
What could go wrong
This is a very early, small study in healthy people only. It is designed to test the imaging method, not to treat any disease, so direct patient benefits are far off.
