Study Type: Interventional

Primary Outcome Measures:
  • Insulin Secretion Rate (ISR) During 190 - 340 Minutes Post-dose [ Time Frame: 190 minutes to 340 minutes ]
    ISR was estimated by the deconvolution of peripheral C-peptide concentrations using a 2-compartment model that utilizes population C-peptide kinetic parameters.


Secondary Outcome Measures:
  • Glucose Infusion Rate (GIR) During 190 - 340 Minutes Post-dose [ Time Frame: 190 minutes to 340 minutes ]
    Glucose Infusion Rate required to maintain the target glucose level of 160 milligrams / deciliter (mg/dL) ; GIR was normalized to subject's body weight (kg).
