Primary Outcome Measures:
  • Change in HbA1c From Baseline to Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Change in HbA1c from baseline to Week 26


Secondary Outcome Measures:
  • Percentage of Patients Achieving HbA1c <=7.0% at Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Percentage of patients achieving HbA1c <=7.0% at Week 26 (for patients with HbA1c >7% at baseline)

  • Percentage of Patients Achieving HbA1c <=6.5% at Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Percentage of patients achieving HbA1c <=6.5% at Week 26 (for patients with HbA1c >6.5% at baseline)

  • Change in Fasting Serum Glucose (FSG) From Baseline to Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Change in FSG (mmol/L) from Baseline to Week 26

  • Change in Body Weight (BW) From Baseline to Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Change in BW (kg) from Baseline to Week 26

  • Change in Total Cholesterol From Baseline to Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Change in Total Cholesterol (mmol/L) from Baseline to Week 26

  • Change in High-density Lipoprotein Cholesterol (HDL) From Baseline to Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Change in HDL (mmol/L) from Baseline to Week 26

  • Ratio of Triglycerides at Week 26 to Baseline [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Ratio of Triglycerides (measured in mmol/L) at Week 26 to Baseline. Log (Postbaseline Triglycerides) - log (Baseline Triglycerides); change from baseline to endpoint is presented as ratio of endpoint to baseline.

  • Change in Blood Pressure From Baseline to Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Change in Systolic Blood Pressure (mmHg) and Diastolic Blood Pressure (mmHg) from Baseline to Week 26

  • Assessment on Event Rate of Treatment-emergent Hypoglycemic Episodes [ Time Frame: Baseline to Week 26 ] [ Designated as safety issue: Yes ]
    Major hypoglycemia: any episode with symptoms consistent with hypoglycemia that resulted in loss of consciousness or seizure with prompt recovery in response to administration of glucagon or glucose or documented hypoglycemia (blood glucose <3.0 mmol/L [54 mg/dL]) and required the assistance of another person. Minor hypoglycemia: any time a patient felt that he or she was experiencing a sign or symptom of hypoglycemia that was self-treated or resolved on its own and had a blood glucose level <3.0 mmol/L (54 mg/dL) and not classified as major hypoglycemia.
