Intravenous Exenatide (Byetta) During Surgery

Intravenous Exenatide (Byetta) for the Treatment of Perioperative Hyperglycemia: Rollover Phase I/II Trial

• Status: Completed
• Phase: Phase 1 / Phase 2
• Study type: Interventional

• Healthy volunteers: Not accepted

Summary

The purpose of this project is to study if intravenous Exenatide is effective at maintaining normal blood glucose levels and preventing low blood glucose levels during surgery.

Detailed description

This is a single-center, block randomized, double-blind, placebo-controlled, dose-ranging study. Subjects will be randomized in equal proportions to one of three treatment arms: placebo of normal saline solution, 0.27 ng/kg/min (0.066 pmol/kg/min) IV Exenatide, and 0.41 ng/kg/min (0.099 pmol/kg/min) IV Exenatide. We will use a block number of 30 (please see power analysis) so that balance between each of the three groups will be maintained over the enrollment period. We will stratify the randomization scheme to ensure balance of diabetics and non-diabetics within the groups.

Conditions

• Euglycemia
• Hypoglycemia
• Hyperglycemia

Interventions

Type	Name	Description
DRUG	Exenatide 0.27 ng/kg/min	Exenatide to be infused intravenously at 0.27 ng/kg/min (0.066 pmol/kg/min) for a duration of 3 to 6 hours. * Induction of anesthesia will be equal to Intubation time. Infusion will begin at this time point (+ or - 3 minutes). * Blood samples will be obtained prior to intubation and then 10 and 30 minutes after drug initiation and every 30 minutes (+ or - 2 minutes) thereafter until the infusion is stopped. The drug infusion will be stopped at extubation. Blood will then be sampled every 30 minutes (+ or - 2 minutes) post extubation for 2 hours, and once 24 hours after extubation. * Blood plasma levels will be collected (8-10 mls) for analysis of GLP-1, Glucose, Potassium, Insulin, Glucagon, Epinephrine, Norepinephrine, Cortisol, and free fatty acids (FFA).
DRUG	Exenatide 0.41 ng/kg/min	Exenatide to be infused intravenously 0.41 ng/kg/min (0.099 pmol/kg/min) for a duration of 3 to 6 hours Induction of anesthesia will be equal to Intubation time. Infusion will begin at this time point (+ or - 3 minutes). * Blood samples will be obtained prior to intubation and then 10 and 30 minutes after drug initiation and every 30 minutes (+ or - 2 minutes) thereafter until the infusion is stopped. The drug infusion will be stopped at extubation. Blood will then be sampled every 30 minutes (+ or - 2 minutes) post extubation for 2 hours, and once 24 hours after extubation. * Blood plasma levels will be collected (8-10 mls) for analysis of GLP-1, Glucose, Potassium, Insulin, Glucagon, Epinephrine, Norepinephrine, Cortisol, and free fatty acids (FFA).
DRUG	Placebo	Intravenous Placebo of NSS infused at same rate as drug comparator. Induction of anesthesia will be equal to Intubation time. Infusion will begin at this time point (+ or - 3 minutes). * Blood samples will be obtained prior to intubation and then 10 and 30 minutes after drug initiation and every 30 minutes (+ or - 2 minutes) thereafter until the infusion is stopped. The drug infusion will be stopped at extubation. Blood will then be sampled every 30 minutes (+ or - 2 minutes) post extubation for 2 hours, and once 24 hours after extubation. * Blood plasma levels will be collected (8-10 mls) for analysis of GLP-1, Glucose, Potassium, Insulin, Glucagon, Epinephrine, Norepinephrine, Cortisol, and free fatty acids (FFA).
