What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in HbA1c at Week 12
Time Frame: at Week 0 and Week 12
The change from Baseline in HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at Week 12. Least squares means were derived from an analysis of covariance (ANCOVA) model with treatment as a fixed effect and baseline HbA1c as a covariate.
at Week 0 and Week 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Fasting Plasma Glucose at Week 12
Time Frame: at Week 0 and Week 12
The change from Baseline in Fasting Plasma Glucose collected at Week 12. Least squares means were derived from an analysis of covariance (ANCOVA) model with treatment as a fixed effect and baseline Fasting Plasma Glucose as a covariate.
at Week 0 and Week 12
Change From Baseline in the Areas Under the Curve From 0 to 2 h (AUC0-2h) for Postprandial Plasma Glucose at Week 12
Time Frame: 0, 0.5, 1, 2 hours post-dose at Week 0 and Week 12
The change from Baseline in AUC0-2h for Postprandial Plasma Glucose collected at Week 12. Least squares means were derived from an analysis of covariance (ANCOVA) model with treatment as a fixed effect and baseline AUC0-2h for Postprandial Plasma Glucose as a covariate.
0, 0.5, 1, 2 hours post-dose at Week 0 and Week 12
Change From Baseline in 2-hour Postprandial Plasma Glucose at Week 12
Time Frame: at Week 0 and Week 12
The change from Baseline in 2-hour Postprandial Plasma Glucose collected at Week 12. Least squares means were derived from an analysis of covariance (ANCOVA) model with treatment as a fixed effect and baseline 2-hour Postprandial Plasma Glucose as a covariate.
at Week 0 and Week 12
