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

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.
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.

The disease, disorder, syndrome, illness, or injury that is being studied.
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.
Experimental: 68Ga-pentixather PET/CT and 68Ga-pentixafor PET/CT scan
Participants with multiple myeloma will perform 68Ga-pentixather PET/CT and 68Ga-pentixafor PET/CT within 7-day interval
Drug: - 68Ga-Pentixather
After intravenous injection of 68Ga-pentixather, PET/CT scan will be performed.
Drug: - 68Ga-Pentixafor
After intravenous injection of 68Ga-pentixafor, PET/CT scan will be performed.
