PET Imaging Study of 68Ga-NB381 in Multiple Myeloma
Recruiting · Early Phase 1 · Peking University First Hospital · registry updated 2026-04-16
Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
Multiple myeloma (MM) predominantly affects the elderly, often presenting insidiously and with a rising incidence rate. Current diagnostic methods primarily rely on invasive bone marrow biopsies, which can lead to false-negative results if the biopsy site is improperly chosen. CD38 is significantly overexpressed on the surface of malignant plasma cells in MM, making it a characteristic tumor biomarker for this disease. Addressing the limitations in specificity and sensitivity of traditional PET imaging agents, this project is dedicated to developing a new type of nanobody PET/CT imaging probe, 68Ga-NB381, which possesses high affinity and targets CD38. This probe, which is an intellectual property of our institution, aims to enhance the accuracy and specificity of early MM diagnosis. In terms of clinical evaluation, the project will implement a comprehensive assessment process including case selection, collection of baseline information, high-precision imaging, expert-level image interpretation, and follow-up studies, comparing directly with traditional 18F-FDG imaging to thoroughly verify the specificity and safety of 68Ga-NB381....
