Outcomes
Primary Outcome Measures
Incremental Post-prandial 4-hour Weighted Mean Active Glucagon-like Peptide-1 (GLP-1) Plasma Concentrations
Meal was given 2 hours postdose. Blood samples for determination of active GLP-1 concentration were collected (4 hours postmeal) on Day 2 in each treatment period.
Secondary Outcome Measures
β-cell Sensitivity
β-cell sensitivity was defined as the incremental post-prandial
4-hour area under the curve (AUC) for insulin secretion rate (ISR) normalized by the incremental post-prandial 4-hour plasma glucose AUC.
Incremental Post-prandial 4-hour Weighted Mean Plasma Glucose Concentrations
Meal was given 2 hours postdose. Blood samples for determination of glucose concentration were collected (4 hours postmeal) on Day 2 in each treatment period.
