Primary Outcome Measures :
  1. Change From Baseline in HbA1c (Glycosylated Hemoglobin) After 24 Weeks [ Time Frame: baseline, 24 weeks ]
    Glycosylated hemoglobin is reported as a percentage of the total hemoglobin


Secondary Outcome Measures :
  1. Change From Baseline in HbA1c (Glycosylated Hemoglobin) After 6 Weeks [ Time Frame: baseline, 6 weeks ]
    Glycosylated hemoglobin is reported as a percentage of the total hemoglobin

  2. Change From Baseline in HbA1c (Glycosylated Hemoglobin) After 12 Weeks [ Time Frame: baseline, 12 weeks ]
    Glycosylated hemoglobin is reported as a percentage of the total hemoglobin

  3. Change From Baseline in HbA1c (Glycosylated Hemoglobin) After 18 Weeks [ Time Frame: baseline, 18 weeks ]
    Glycosylated hemoglobin is reported as a percentage of the total hemoglobin

  4. Occurrence of Absolute Efficacy Response (HbA1c < 7%) After 24 Weeks [ Time Frame: 24 weeks ]
    Glycosylated hemoglobin is reported as a percentage of the total hemoglobin

  5. Occurrence of Absolute Efficacy Response (HbA1c < 6.5%) After 24 Weeks [ Time Frame: 24 weeks ]
    Glycosylated hemoglobin is reported as a percentage of the total hemoglobin

  6. Occurrence of Relative Efficacy Response (Reduction in HbA1c >= 0.5%) After 24 Weeks [ Time Frame: 24 weeks ]
    Glycosylated hemoglobin is reported as a percentage of the total hemoglobin

  7. Change From Baseline in Fasting Plasma Glucose (FPG) After 24 Weeks [ Time Frame: baseline, 24 weeks ]
    Adjusted mean change in fasting plasma glucose (FPG) from baseline at week 24

  8. Change From Baseline in Fasting Plasma Glucose (FPG) After 6 Weeks [ Time Frame: baseline, 6 weeks ]
    Adjusted mean change in fasting plasma glucose (FPG) from baseline at week 6

  9. Change From Baseline in Fasting Plasma Glucose (FPG) After 12 Weeks [ Time Frame: baseline, 12 weeks ]
    Adjusted mean change in fasting plasma glucose (FPG) from baseline at week 12

  10. Change From Baseline in Fasting Plasma Glucose (FPG) After 18 Weeks [ Time Frame: baseline, 18 weeks ]
    Adjusted mean change in fasting plasma glucose (FPG) from baseline at week 18
