Trial Outcomes & Findings for Effect of Exendin (9-39) on Glucose Requirements to Maintain Euglycemia (NCT NCT00835328)

NCT ID: NCT00835328

Last Updated: 2020-06-01

Results Overview

To assess the effect of Exendin (9-39) on glucose infusion rate, glucose infusion rate (GIR) over the last 2 hours of the treatment period was calculated by adding the total amount of intravenous glucose (mg) received over 2 hours divided by the weight (kg) and by time (120 min) during infusion of Exendin (9-39) and normal saline vehicle.

Participant Flow

Participants were recruited based on a confirmed clinical diagnosis of congenital hyperinsulinism at 1 academic medical center between August 2009 and October 2019. The first participant was enrolled on August 26, 2008 and the last participant was enrolled in January 25, 2017.

Of the 14 enrolled participants, 13 met inclusion criteria and were randomized to treatment.

Measure
Exendin (9-39) 0.02 mg/kg/hr
Cohort 1: Participants will be administered 0.02 mg/kg/hr of Exendin (9-39) and vehicle (normal saline), via continuous intravenous infusion, over 9 hours on two separate days in random order, with 3 hours of follow-up after the last dose is administered or until blood glucose is \< 70 mg/dL (whichever comes first). Glucose infusion rates (GIR) will be titrated three hours prior to infusions to keep blood glucose in the range of 70-90 mg/dL. During both infusions, blood glucose will be measured every 30 minutes.
Exendin (9-39) 0.04 mg/kg/hr
Cohort 2: Participants will be administered 0.04 mg/kg/hr of Exendin (9-39) and vehicle (normal saline), via continuous intravenous infusion, over 9 hours on two separate days in random order, with 3 hours of follow-up after the last dose is administered or until blood glucose is \< 70 mg/dL (whichever comes first). Glucose infusion rates (GIR) will be titrated three hours prior to infusions to keep blood glucose in the range of 70-90 mg/dL. During both infusions, blood glucose will be measured every 30 minutes.
Exendin (9-39) 0.10 mg/kg/hr
Cohort 3: Participants will be administered 0.10 mg/kg/hr of Exendin (9-39) and vehicle (normal saline), via continuous intravenous infusion, over 6 hours on two separate days in random order, with 3 hours of follow-up after the last dose is administered or until blood glucose is \< 70 mg/dL (whichever comes first). Glucose infusion rates (GIR) will be titrated three hours prior to infusions to keep blood glucose in the range of 70-90 mg/dL. During both infusions, blood glucose will be measured every 30 minutes.
Exendin (9-39) 0.20 mg/kg/hr
Cohort 4: Participants will be administered 0.20 mg/kg/hr of Exendin (9-39) and vehicle (normal saline), via continuous intravenous infusion, over 9 hours on two separate days in random order, with 3 hours of follow-up after the last dose is administered or until blood glucose is \< 70 mg/dL (whichever comes first). Glucose infusion rates (GIR) will be titrated three hours prior to infusions to keep blood glucose in the range of 70-90 mg/dL. During both infusions, blood glucose will be measured every 30 minutes.

PRIMARY outcome

Timeframe: Up to 9 hours after the initiation of infusion

Population: Subjects served as their own control for comparison between the effects of Exendin (9-39) and the normal saline vehicle. The trial was terminated after 14 participants enrolled in the study. No data is available for any outcome measures.

To assess the effect of Exendin (9-39) on glucose infusion rate, glucose infusion rate (GIR) over the last 2 hours of the treatment period was calculated by adding the total amount of intravenous glucose (mg) received over 2 hours divided by the weight (kg) and by time (120 min) during infusion of Exendin (9-39) and normal saline vehicle.

Population: Subjects served as their own control for comparison between the effects of Exendin (9-39) and the normal saline vehicle. The trial was terminated after 14 participants enrolled in the study. No data is available for any outcome measures.

The following PK variables of interest include AUC0-∞, AUC0-t, maximal concentration (Cmax), time to maximal concentration (Tmax), concentration at end of infusion (Ceoi), steady state volume of distribution (Vss), clearance (CL) and half-life (t1/2) of Exendin (9-39). These will be derived through both non-compartmental and model-based methods.
