NCT05034783

Brief Summary

Glucagon-like peptide-1 receptor (GLP-1R)-targeted PET imaging with 68Ga-labeled compounds is able to provide superior sensitivity and specificity to detect insulinoma, like the widely studied \[68Ga\]Ga-NOTA-exendin-4. This pilot study was prospectively designed to evaluate the early dynamic distribution of \[68Ga\]Ga-HBED-CC-exendin-4, a novel radiopharmaceutical targeting GLP-1R, which was compared with \[68Ga\]Ga-NOTA-exendin-4 in the same group of insulinoma patients.

Outcome Measures

Primary Outcomes (1)

  • Metabolic parameters

    the early dynamic distribution (SUVmax in tumor lesions and SUVmean in normal organs at different time points) of \[68Ga\]Ga-HBED-CC-exendin-4 in comparison with \[68Ga\]Ga-NOTA-exendin-4 in the same group of insulinoma patients.

    through study completion, an average of 1 year

Secondary Outcomes (1)

  • Diagnostic value

    through study completion, an average of 1 year

Other Outcomes (1)

  • GLP-1R expression and SUV

    through study completion, an average of 1 year

Study Arms (1)

[68Ga]Ga-HBED-CC-exendin-4 and [68Ga]Ga-NOTA-exendin-4 PET/ CT scan

EXPERIMENTAL

Patients of Insulinoma PET/CT imaging: In two consecutive days each patient underwent a 60-min dynamic PET/CT scan after intravenous administration of \[68Ga\]Ga-HBED-CC-exendin-4 and \[68Ga\]Ga-NOTA-exendin-4, respectively.

Drug: [68Ga]Ga-HBED-CC-exendin-4Drug: [68Ga]Ga-NOTA-exendin-4

Interventions

Intravenous injection of one dosage of 74-111 MBq (2-3 mCi) \[68Ga\]Ga-HBED-CC-exendin-4. Tracer doses of \[68Ga\]Ga-HBED-CC-exendin-4 will be used to image lesions of insulinoma by PET/CT.
