Primary Outcome Measures:
  • Change in HbA1c From Baseline to Week 30 [ Time Frame: Day -3, Week 30 ] [ Designated as safety issue: No ]
    Absolute change in HbA1c from baseline (Day -3) to Week 30 [Week 30 - Baseline]


Secondary Outcome Measures:
  • Percentage of Subjects Achieving HbA1c Target of <7% [ Time Frame: Week 30 ] [ Designated as safety issue: No ]
    Percentages of subjects achieving HbA1c target value of <7% at Week 30.

  • Percentage of Subjects Achieving HbA1c Target of <=6.5% [ Time Frame: Week 30 ] [ Designated as safety issue: No ]
    Percentages of subjects achieving HbA1c target values of <=6.5% at Week 30.

  • Percentage of Subjects Achieving HbA1c Target of <=6.0% [ Time Frame: Week 30 ] [ Designated as safety issue: No ]
    Percentages of subjects achieving HbA1c target values of <=6.0% at Week 30.

  • Change in Body Weight From Baseline to Week 30 [ Time Frame: Day -3, Week 30 ] [ Designated as safety issue: No ]
    Change in body weight from baseline (Day -3) to Week 30

  • Change in Fasting Plasma Glucose From Baseline to Week 30 [ Time Frame: Day -3, Week 30 ] [ Designated as safety issue: No ]
    Change in fasting plasma glucose from baseline (Day -3) to Week 30.

  • Change in Blood Pressure From Baseline to Week 30 [ Time Frame: Day -3, Week 30 ] [ Designated as safety issue: No ]
    Change in Sitting Diastolic Blood Pressure and Sitting Systolic Blood Pressure from baseline to Week 30

  • Change in Total Cholesterol From Baseline to Week 30 [ Time Frame: Day -3, Week 30 ] [ Designated as safety issue: No ]
    Change in total cholesterol from baseline (Day -3) to Week 30.

  • Change in High-density Lipoprotein (HDL) From Baseline to Week 30 [ Time Frame: Day -3, Week 30 ] [ Designated as safety issue: No ]
    Change in high-density lipoprotein (HDL) from baseline (Day -3) to Week 30.

  • Ratio of Triglycerides at Week 30 to Baseline [ Time Frame: Day -3, Week 30 ] [ Designated as safety issue: No ]
    Ratio of triglycerides (measured in mg/dL) at Week 30 to baseline (Day -3). Log (Postbaseline Triglycerides) - log (Baseline Triglycerides); change from baseline to endpoint is presented as ratio of endpoint to baseline.

  • Exenatide LAR Pharmacokinetics Parameters [ Time Frame: Week 29 to Week 30 ] [ Designated as safety issue: No ]
    Steady-state plasma exenatide concentration over the dosing interval of Week 29 to Week 30 (0-168 hours) was evaluated. Geometric mean for the average steady-state concentration and its 10th and 90th percentiles were reported.

  • Assessment on Event Rate of Treatment-emergent Major Hypoglycemic Events [ Time Frame: Day 1 to Week 30 ] [ Designated as safety issue: Yes ]
    The major hypoglycemia category included events that, in the judgment of the investigator or physician, resulted in loss of consciousness, seizure, coma, or other change in mental status consistent with neuroglycopenia, in which symptoms resolved after administration of intramuscular glucagon or intravenous glucose, required third-party assistance, and was accompanied by a blood glucose concentration of less than 54 mg/dL prior to treatment, whether or not symptoms of hypoglycemia were perceived by the subject.

  • Assessment on Event Rate of Treatment-emergent Minor Hypoglycemic Events [ Time Frame: Day 1 to Week 30 ] [ Designated as safety issue: Yes ]
    The minor hypoglycemia were accompanied by a blood glucose concentration of less than 54 mg/dL prior to treatment and not classified as major hypoglycemia.

  • Change in 2 Hours (2h) Postprandial Glucose From Baseline to Week 14 [ Time Frame: Day -3, Week 14 ] [ Designated as safety issue: No ]
    Change in 2h Postprandial Glucose from baseline (Day -3) to Week 14
