NCT02560376

Brief Summary

This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-exendin-4 in insulinoma and nesidioblastosis patients. A single dose of 55.5-111 Mega-Becquerel (MBq) 68Ga-NOTA-exendin-4 will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.

Outcome Measures

Primary Outcomes (1)

  • Standardized uptake value of 68Ga-NOTA-exendin-4 PET/CT in Diagnosis of Insulinoma and Nesidioblastosis

    1 year

Secondary Outcomes (1)

  • Adverse events collection

    1 week

Study Arms (1)

68Ga-NOTA-exendin-4 PET/CT

EXPERIMENTAL

The patients were injected with 55.5-111 MBq of 68Ga-NOTA-exendin-4 PET/CT in one dose intravenously and underwent PET/CT scan 30-60 min later.

Drug: 68Ga-NOTA-exendin-4

Interventions

68Ga-NOTA-exendin-4 were injected into the patients before the PET/CT scans

Also known as: 68Ga-NOTA-MAL-cys40-exendin-4

Eligibility Criteria

Age6 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with hypoglycaemia in the presence of neuroglycopenic symptoms and documented Whipple's triad.
  • Biochemically proven endogenous hyperinsulinemic hypoglycaemia (plasma glucose concentration \<3.0 mM, insulin \>3 µU/ml, and C-peptide \>0.6 ng/ml).
  • Conventional imaging within 1 month
  • Signed written consent
  • Age above 6 years (congenital hyperinsulinemic with the symptoms onset in school age is also the subject of this study)

You may not qualify if:

  • Pregnancy
  • Breastfeeding
  • Renal function: serum creatinine \> 3.0 mg/dl
  • Known allergy against exendin-4
  • Any medical condition that, in the opinion of the investigator, may significantly interfere with study compliance.
