A Pilot Study of Novel Imaging Modalities in Monoclonal Gammopathy of Undetermined Significance (MGUS), Smoldering Multiple Myeloma (SMM), and Multiple Myeloma (MM)
In Brief
A Phase 2 clinical trial evaluating 18-NaF PET, DCE-MRI, and 1 other intervention for Multiple Myeloma and 2 related conditions. Completed, enrolled 31 participants across 1 site.
Detailed Summary
Background: \- Recent studies have shown that the premalignant conditions monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM) have a high risk of progressing to multiple myeloma (MM). There are currently no known effective treatments to prevent MGUS or SMM from developing into MM, and there are no known tests for determining whether an individual with MGUS or SMM will develop MM. Researchers are investigating new and improved imaging techniques that may be able to better detect the progression of MGUS or SMM into MM. Objectives: * To compare the results of three imaging techniques in individuals with MGUS, SMM, and MM. * To correlate the information from the imaging studies with established clinical markers of progression from MGUS/SMM to MM. Eligibility: \- Individuals at least 18 years of age who have been diagnosed with monoclonal gammopathy of undetermined significance, smoldering multiple myeloma, or multiple myeloma. Design: * Participants will be screened with a physical examination and medical history, and will provide baseline blood, urine, and bone marrow samples before beginning the imaging studies. * Participants will have three imaging studies on separate days: a standard 18-fludeoxyglucose positron emission tomography/computed tomography scan (18-FDG PET/CT), a PET/CT scan with an experimental sodium fluoride-based drug (18-NaF PET/CT), and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). * Participants will be closely monitored during each scan, and will provide additional blood samples before and after the scans. * Participants may provide additional blood, urine, tissue, and bone marrow samples for optional research studies.

Timeline
Interventions
The patient will receive 5mCi of F-18 NaF IV (intravenous) bolus, followed by a \~20 ml saline (sodium chloride IV infusion 0.9% w/v) flush over a period of \~20 seconds. Serial dynamic imaging (2 minutes/bed position) will be obtained over a 1-hour period. The patient will be permitted an imaging break until a static PET/CT is performed beginning at 2-hours post F-18 NaF injection.
An FDA (Food and Drug Administration) approved gadolinium chelate (e.g. Magnevist, Berlex Laboratories, NJ, USA) will be administered intravenously at 3 cc/sec using an automated pump injector (Medrad, Pittsburgh, PA, USA).
The 18F-FDG injection procedure will be injected and be followed by a \~20 ml saline (sodium chloride IV infusion 0.9% w/v) flush over a period of \~20 seconds. The injection site will be evaluated pre- and post administration for any reaction (e.g. bleeding, hematoma, redness, or infection). Whole body (vertex to toes) static PET/CT imaging will be performed beginning at 1-hour, and again at 2-hours post injection.
