Measure
Vehicle First Then Exendin-(9-39)
An infusion of vehicle (0.9%NaCl) will run for 60 minutes(time -60 to 0) before starting the study infusion of vehicle or exendin-(9-39). At time 0, vehicle (0.9%NaCl) will be started and will continue for 6 hours. The following day, at time 0, exendin-(9-39) at a dose ranging from 100-500pmol/kg/min will be started and continue for 6 hours. During both infusions, blood glucose, insulin, c-peptide, glucagon-like peptide-(GLP-1) , and glucagon will be measured every 30 minutes. Vehicle: (0.9% NaCl)

Measure
Subject Population
n=16 Participants
9 subjects were randomized to the vehicle first arm and the next day they were switched to exendin- (9-39). 7 subjects were randomized to the exendin-(9-39) first arm and the next day they were switched to vehicle. All subjects enrolled and treated in the protocol served as their own control. Because of this and the small sample size, baseline characteristic data is presented together.
