Primary Outcome Measures :
  1. Change From Baseline in Hemoglobin A1c (HbA1c) (10 mg and 15 mg) [ Time Frame: Baseline, Week 40 ]
    HbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured primarily to identify average plasma glucose concentration over prolonged periods of time. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Treatment + Time + Treatment*Time (Type III sum of squares).


Secondary Outcome Measures :
  1. Change From Baseline in HbA1c (5 mg) [ Time Frame: Baseline, Week 40 ]
    HbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured primarily to identify average plasma glucose concentration over prolonged periods of time. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Treatment + Time + Treatment*Time (Type III sum of squares).

  2. Change From Baseline in Body Weight [ Time Frame: Baseline, Week 40 ]
    Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment + Time + Treatment*Time (Type III sum of squares).

  3. Percentage of Participants Achieving an HbA1c Target Value of <7% [ Time Frame: Week 40 ]
    Hemoglobin A1c (HbA1c) is the glycosylated fraction of hemoglobin A. HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time.

  4. Change From Baseline in Fasting Serum Glucose (FSG) [ Time Frame: Baseline, Week 40 ]
    Fasting serum glucose (FSG) is a test to determine sugar levels in serum sample after an overnight fast. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment + Time + Treatment*Time (Type III sum of squares).

  5. Mean Change From Baseline in Daily Average 7-Point Self-Monitored Blood Glucose (SMBG) Values [ Time Frame: Baseline, Week 40 ]
    The self-monitored plasma glucose (SMBG) data were collected at the following 7 time points: Morning Premeal - Fasting, Morning 2-hour Postmeal, Midday Premeal, Midday 2-hour Postmeal, Evening Premeal, Evening 2-hour Postmeal and Bedtime. Least Squares (LS) mean was determined by mixed-model repeated measures (MMRM) model with Baseline + Pooled Country + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment + Time + Treatment*Time (Type III sum of squares).

  6. Percentage of Participants Who Achieved Weight Loss ≥5% [ Time Frame: Week 40 ]
    Percentage of Participants who Achieved Weight Loss ≥5%.

  7. Diabetes Treatment Satisfaction as Measured by the Diabetes Treatment Satisfaction Questionnaire, Change Version (DTSQc) Hyperglycemia, Hypoglycemia and Total Score [ Time Frame: Baseline, Week 40 ]
    DTSQc, an 8-item questionnaire, assesses relative change in treatment satisfaction perceived frequency of hyperglycemia, and perceived frequency of hypoglycemia from baseline to week 40 or early termination. The questionnaire consists of 8 items, 6 of which (1 and 4 through 8) assess treatment satisfaction. Each item is rated on a 7-point Likert scale. The scores from the 6 treatment satisfaction items are summed to a Total Treatment Satisfaction Score, which ranges from -18 to 18 where the higher the score the greater the improvement in satisfaction with treatment. The lower the score the greater the deterioration in satisfaction with treatment. The hyperglycemia and hypoglycemia scores range from -3 to 3 where negative scores indicate fewer problems with blood glucose levels and positive scores indicate more problems than before. LS Mean was determined by ANCOVA with Baseline DTSQs + Pooled Country + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment (Type III sum of squares).

  8. Rate of Hypoglycemia With Blood Glucose <54 Milligram/Deciliter (mg/dL) [<3.0 Millimole/Liter (mmol/L)] or Severe Hypoglycemia [ Time Frame: Baseline through Safety Follow-Up (Up to Week 44) ]
    The hypoglycemia events were defined by participant reported events with blood glucose <54mg/dL) (<3.0 mmol/L] or severe hypoglycemia. Severe hypoglycemia is defined as an episode with severe cognitive impairment requiring the assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. These episodes may be associated with sufficient neuroglycopenia to induce seizure or coma. The rate of postbaseline hypoglycemia was estimated by negative binomial model: number of episodes = Pooled Country + Baseline HbA1c Group (<=8.5%, >8.5%) + Treatment.

  9. Percentage of Participants Achieving an HbA1c Target Value of <5.7% [ Time Frame: Week 40 ]
    Percentage of Participants Achieving an HbA1c Target Value of <5.7%.
