Radioactive probe lights up CD73 on breast tumors in PET scans
NCT ID NCT06411678
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers are testing a radioactive tracer called 68Ga-DOTA-dPNE that binds to the CD73 protein on breast cancer cells. Women with breast cancer receive the tracer intravenously and then undergo PET/CT scans. The study checks how well the tracer detects tumors, bones, and lymph nodes compared with standard 18F-FDG imaging, and whether it can help guide treatment decisions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 68Ga-DOTA-dPNE, a radioactive tracer that binds to the CD73 protein on tumors
- What this could lead to
- If it works, this tracer could offer a non-invasive way to map CD73 in breast cancer, helping doctors choose or monitor targeted therapies.
- What could go wrong
- This is an early-phase imaging study with 50 participants. The tracer may not bind reliably to tumors, and results from this small group may not apply to all breast cancers.
