Primary Outcome Measures:
  • Change From Baseline in Hemoglobin A1c (A1C) at Week 18 [ Time Frame: Baseline and Week 18 ] [ Designated as safety issue: No ]
    A1C is measured as percent. Thus, this change from baseline reflects the Week 18 A1C percent minus the Week 0 A1C percent.


Secondary Outcome Measures:
  • Number of Patients With A1C < 7.0% at Week 18 [ Time Frame: Week 18 ] [ Designated as safety issue: No ]
  • Change From Baseline in Fasting Plasma Glucose (FPG) at Week 18 [ Time Frame: Baseline and Week 18 ] [ Designated as safety issue: No ]
    FPG is measured as mg/dL. Thus, this change from baseline reflects the Week 18 FPG mg/dL minus the Week 0 FPG mg/dL.
