PET/MR with a CXCR4 tracer versus standard PET/CT and MRI for initial staging and follow-up in multiple myeloma

Official title: [68Ga]Ga-PentixaFor (CXCR4) PET/MR for Initial Staging and Follow up in Multiple Myeloma: Prospective Comparison With Standard of Care PET/CT and Evaluation of Therapy Influence

Run by University Health Network, Toronto · NCT06871176 · Data updated 2026-11-12

This test will see if a PET/MR scan using a new tracer called [68Ga]Ga-PentixaFor finds multiple myeloma in bones more accurately than standard PET/CT and MRI for adults at diagnosis or follow-up.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with a clinical diagnosis of multiple myeloma—including nonsecretory, oligosecretory, or suspected extramedullary disease—who are newly diagnosed or undergoing staging/follow-up and can tolerate MRI and PET/CT are ideal candidates.

Probably not a fit

Patients who are pregnant or breastfeeding, unable to lie still for imaging, have contraindications to MRI or PET/CT or known allergy to the tracer components, or have another active hematologic malignancy are unlikely to be eligible or to benefit.

What this trial studies

This interventional study compares a combined PET/MR scan using the CXCR4-targeted tracer [68Ga]Ga-PentixaFor to standard 18F-FDG PET/CT and conventional MRI in people with multiple myeloma. Participants (adults, newly diagnosed or being evaluated around stem cell transplantation) will undergo both imaging approaches for initial staging and follow-up. Investigators will compare lesion detection, diagnostic accuracy, prognostic information, and the frequency with which imaging influences treatment decisions. The aim is to see whether CXCR4 PET/MR gives more precise disease mapping and could reduce the need for multiple separate imaging sessions.

Why it matters

Potential benefit: If successful, this imaging approach could detect bone and extramedullary myeloma more precisely, improve staging and treatment planning, and reduce the number of separate scans patients need.

How similar studies have gone: CXCR4-targeted PET imaging such as [68Ga]Ga-PentixaFor is a relatively new but promising approach with preliminary studies showing improved lesion detection in some myeloma patients, though it is not yet as widely validated as 18F-FDG PET/CT.
