Clinical Trial Summary

The purpose of this study is to determine if Exendin-(9-39), an antagonist of the glucagon-like peptide-1 (GLP-1) receptor with effects on the pancreatic beta cell, increases fasting blood glucose levels in subjects with congenital hyperinsulinism.


Clinical Trial Description

This is an open-label, pilot study , to determine if Exendin-(9-39), an antagonist of the glucagon-like peptide-1 (GLP-1) receptor with effects on the pancreatic beta cells, increases fasting blood glucose levels in subjects with congenital hyperinsulinism. Our overall hypothesis is that abnormal GLP-1 secretion resulting from dysfunctional nutrient sensing in intestinal L-cells plays a role in the dysregulated insulin secretion characteristic of this disorder, and that antagonism of the GLP-1 receptor will increase fasting blood glucose levels.

Aim 1. To evaluate the dose of exendin-(9-39) required to elevate fasting blood glucose levels in subjects with congenital hyperinsulinism due to KATP channel mutations.

Aim 2. To determine therapeutic plasma levels, plasma half-life and pharmacokinetics of exendin-(9-39) during an intravenous short-term infusion in subjects with congenital hyperinsulinism due to Adenosine triphosphate (ATP)-sensitive potassium channel (KATP) mutations. ;
