Primary Outcome Measures:
  • Change in HbA1c (Glycosylated Hemoglobin) From Baseline to Week 28 [ Time Frame: Baseline to Week 28 ]
    Absolute change in HbA1c from baseline (Day 1, Visit 3) to Week 28/Study Termination (Visit 11). Hypothesis testing on the primary endpoint followed a serial gated procedure with all tests carried out at a 2-sided significance level of 0.05 to protect the family-wise error rate. These tests were conducted sequentially, and are presented in the statistical analysis section below in the order in which they were performed; each test was the gatekeeper of later tests.

Secondary Outcome Measures:
  • Percentage of Subjects Achieving HbA1c <7% at Week 28 [ Time Frame: Baseline to Week 28 ]
    Percentage of subjects achieving HbA1c target values of < 7.0% at Week 28/Study Termination.

  • Change in Fasting Plasma Glucose Concentrations From Baseline to Week 28 [ Time Frame: Baseline to Week 28 ]
    The change in fasting plasma glucose concentrations from baseline (Day 1) to Week 28/Study Termination.

  • Change in Body Weight (kg) From Baseline to Week 28 [ Time Frame: Baseline to Week 28 ]
    The change in body weight (kg) from baseline (Day 1) to Week 28/Study Termination.

  • Change in 2-hour Postprandial Glucose Concentrations From Baseline to Week 16 (Visit 8) [ Time Frame: Baseline to Week 16 ]
    The change in 2-hour postprandial plasma glucose from baseline (Day 1) to Visit 8 (Week 16) was analyzed using a general linear model including treatment, and baseline HbA1c stratum (< 9% or ≥ 9%) as fixed factors, and the baseline 2-hour postprandial plasma glucose concentrations as a covariate.
