68Ga-pentixather and 68Ga-pentixafor PET/CT in Multiple Myeloma

Study Purpose

Chemokine receptor-4 (CXCR4) is overexpressed in multiple myeloma (MM) cells. 68Ga-pentixafor is a radio-labled tracer for CXCR4 . 68Ga-pentixafor PET/CT has shown good diagnostic performance in MM. But an exchange of Ga3+ by Lu3+ or Y3+ will lead to a significant loss of CXCR4 affinity. Investigators conduct this prospective study to evaluate the diagnostic performance of 68Ga-pentixather compared with 68Ga-pentixafor, in order to parallel 68Ga-pentixather and 177Lu/90Y-pentixather in theranostics of MM.

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT05364177
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Multiple myeloma (MM) is a malignant plasma cell disorder which is characterized by clonal proliferation of plasma cell in bone marrow microenvironment. Chemokine receptor-4 (CXCR4) is overexpressed in MM cells, and has been identified as a potential therapy target. 68Ga-pentixafor is a radiolabeled ligand with high affinity for CXCR4. 68Ga-pentixafor PET/CT has been reported with better diagnostic performance than 18F-FDG PET/CT. However, considering both diagnostic and therapeutic applications, an exchange of Ga3+ by other M3+ ions (Lu or Y) will lead to a significant loss of CXCR4 affinity. Thus, pentixather was developed as the precursor of 177Lu-pentixather or 90Y-pentixather, which can be used in CXCR4-targeted peptide receptor radionuclide therapy (PRRT). Investigators conduct this prospective study to evaluate the diagnostic performance of 68Ga-pentixather compared with 68Ga-pentixafor, in order to parallel 68Ga-pentixather and 177Lu/90Y-pentixather in theranostics of MM.
