Primary Outcome Measures:
  • Change From Baseline to Week 24 in HbA1c [ Time Frame: Baseline to Week 24 ]
    Efficacy as measured by change in glycated hemoglobin (HbA1c) at Week 24

Secondary Outcome Measures:
  • Proportion of Responders Achieving HbA1c <= 7.0% [ Time Frame: Week 24 ]
    Efficacy as measured in proportion of subjects achieving HbA1c < or = to 7.0%

  • Proportion of Responders Achieving HbA1c <= 6.5% [ Time Frame: Week 24 ]
    Efficacy as measured in proportion of subjects achieving HbA1c < or = to 6.5% at Week 24

  • FPG Change From Baseline to Week 24 [ Time Frame: Baseline to Week 24 ]
    Efficacy as measured by mean change in fasting plasma glucose (FPG)

  • Proportion of Subjects Requiring Rescue Therapy [ Time Frame: Baseline to Week 24 ]
  • Time to Rescue [ Time Frame: Baseline to Week 24 ]
    Time from Week 0 (baseline) to initiation of rescue therapy (up to a maximum of 24 weeks/end of treatment) for subjects not responding to treatment

  • FEV1 Change From Baseline to Week 24 [ Time Frame: Baseline to Week 24 ]
    Forced Expiratory Volume in 1 second - change from baseline to week 24

  • Incidence of Total Hypoglycemia [ Time Frame: Baseline to Week 24 ]
    Hypoglycemia, defined as blood glucose <= 70 mg/dL or in absence of blood glucose, symptoms that are resolved by the administration of carbohydrates.

  • Incidence of Severe Hypoglycemia [ Time Frame: Baseline to Week 24 ]
    Severe Hypoglycemia defined as: Requiring 3rd party assistance.

  • Total Hypoglycemia Event Rate [ Time Frame: Baseline to Week 24 ]
    Number of Hypoglycemic Events/Total Subject Exposure Time (in months)

  • Severe Hypoglycemia Event Rate [ Time Frame: Baseline to Week 24 ]
    Number of Severe Hypoglycemic Events/Total Subject Exposure Time (in months)

  • Mean 7-point Glucose Baseline Values [ Time Frame: Baseline ]
    Mean 7-point self-monitored glucose at baseline

  • Mean 7-point Glucose Week 24 Values [ Time Frame: Week 24 ]
    Mean 7-point self-monitored blood glucose at Week 24

  • Change in Body Weight From Baseline to Week 24 [ Time Frame: Baseline to Week 24 ]
    Change in body weight from Baseline to Week 24
