New imaging test could pinpoint tiny pancreatic tumors in babies, guiding Life-Saving surgery
NCT ID NCT04205604
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a special PET scan using a radioactive tracer called FDOPA can accurately find and locate focal lesions in the pancreas of infants with congenital hyperinsulinism, a condition causing severe low blood sugar. The goal is to help surgeons remove only the diseased part of the pancreas, potentially curing the condition. The study will enroll 50 children, primarily infants under 6 months old, who have been diagnosed with this condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-Fluoro Dopa (a radioactive tracer used in PET imaging)
- What this could lead to
- If successful, this imaging method could help surgeons precisely remove only the diseased part of the pancreas, potentially curing focal congenital hyperinsulinism without removing the whole organ.
- What could go wrong
- This is a phase 2 study with only 50 participants, so results may not apply to all patients. The imaging may not always correctly identify the lesion, leading to incomplete surgery or unnecessary procedures.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Any age, but primarily infants 0-6 months given typical age of initial presentation. * Children with diagnosis of FoHI or DiHI based on clinical criteria (fasting hypoglycemia accompanied by inadequate suppression of plasma insulin, inappropriately low plasma free fatty acid and plasma-hydroxybutyrate concentrations, and an inappropriate glycemic response to glucagon injection) o confirmed by genetic testing for mutations in ABCC8 and KCNJ1 was1. * Hypoglycemia uncontrolled with medical management (diazoxide, octreotide). * Able to withdraw medications in time to wash out prior to the scheduled PET scan. * Patients fulfilling criteria above but with uncontrolled hypoglycemia after initial surgical management (partial or near-total pancreatectomy) * Normal hepatic and renal function. Exclusion Criteria: * Treatment with other, third-line, medications for hyperinsulinism (nifedipine, glucagon). * Patients with hepatic or renal insufficiency.
