New tracer lights up myeloma cells for sharper bone scans
NCT ID NCT06871176
First seen Oct 01, 2026 · Last updated Oct 02, 2026 · Updated 1 time
Summary
Multiple myeloma often hides in bones, and doctors use blood tests plus standard imaging like PET/CT and MRI to find it. This study tests a new radioactive tracer, [68Ga]Ga-PentixaFor, that sticks to a protein called CXCR4 on myeloma cells. Researchers will compare combined PET/MR scans using this tracer against standard scans in 30 adults with newly diagnosed myeloma. They want to see if the new scan finds more bone and organ involvement, and whether it changes how hematologists plan treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a radioactive tracer called [68Ga]Ga-PentixaFor that binds to the CXCR4 protein on myeloma cells
- What this could lead to
- If it works, doctors could get a clearer map of where myeloma has spread in the bones, which may help them choose and adjust treatment.
- What could go wrong
- This is a small imaging study with 30 people, so it may not show a clear advantage over standard scans. The tracer also requires an IV and a PET/MR machine, which not every hospital has.
