GPRC5D Targeted PET/CT Imaging in Plasma Cell Disorders
A Single-Center, Phase I, Single-Arm Prospective Interventional Study of GPRC5D-Targeted PET/CT Imaging in Patients With Multiple Myeloma and Other Plasma Cell Disorders
Source: ClinicalTrials.gov · Last updated 28 Sept 2026
Brief summary (registry, in English)
This is a prospective, single-center, single-arm Phase I study evaluating GPRC5D-targeted PET/CT imaging in patients with plasma cell disorders, including multiple myeloma. Participants will undergo GPRC5D-targeted PET/CT, 18F-FDG PET/CT, and 68Ga-BCMA PET/CT within 5 days whenever feasible for head-to-head comparison of lesion detection and disease assessment. The study aims to evaluate the safety, feasibility, biodistribution, and diagnostic performance of GPRC5D-targeted PET/CT and to compare its imaging characteristics with currently available molecular imaging modalities in plasma cell disorders.
