New PET tracer could spot cancers that standard scans overlook
NCT ID NCT07118176
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This phase 1 trial is testing a new imaging tracer called 68Ga-FAPI-46 to see where it collects in normal and cancerous tissues. About 30 people with various solid tumors or blood cancers will receive the tracer and then undergo a PET/CT scan. The goal is to understand how the tracer behaves in the body and whether it can help detect cancers that standard FDG-PET scans might miss.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Gallium Ga 68 FAPi-46
- What this could lead to
- If successful, this tracer could improve cancer detection and help doctors see tumors that standard scans might miss.
- What could go wrong
- This is an early phase 1 study with only 30 participants, so results may not apply broadly. The tracer may not highlight all cancer types effectively.
