A Molecular Probe Targeting BCMA for the Clinical Diagnosis of Multiple Myeloma
Sponsor: Peking University First Hospital
Summary
Multiple Myeloma (MM), the second most common hematological malignancy, continues to pose challenges in precise clinical identification. As a potential solution, nuclear medicine immuno-PET imaging has emerged as a promising approach. However, traditional full-length antibody probes suffer from delayed tumor uptake peaks and low target-to-background ratios, limiting their clinical utility. In our study, a peptide or nanobody targeting BCMA was developed by computer-aided designing, which was subsequently radiolabeled with 68Ga to create a novel molecular probe, 68Ga-MM-BC1. This research aims to overcome the diagnostic limitations of MM and may also offer valuable insights for molecular-targeted imaging in other malignant tumors.

Interventions
18F-FDG
Prior to the examination, patients will be required to fast for at least 6 hours. 18F-FDG (0.05-0.1 mCi/kg) will be intravenously injected, and one hour after the injection, head and torso imaging will be performed using a Shanghai United Imaging uMI 780 PET/CT scanner, covering the region from the top of the head to the upper third of the thigh. The patient will lie supine and breathe calmly during the procedure. After image acquisition, the data will be reconstructed using the OSEM method to generate coronal, sagittal, transverse, and PET/CT fusion images.
68Ga-BC1
The prepared and quality-controlled 68Ga-BC1 (0.05-0.1 mCi/kg) will be intravenously injected into the patient. Two hours after the injection, whole-body imaging will be performed using a Shanghai United Imaging uMI 780 PET/CT scanner, covering the region from the top of the head to the mid-thigh. If any indeterminate lesions are found during the routine imaging, delayed imaging will be performed for further differentiation. The patient will lie supine and breathe calmly during the procedure. After image acquisition, the data will be reconstructed using the OSEM method to generate coronal, sagittal, transverse, and PET/CT fusion images.
