Collaborator:
Eli Lilly and Company
Information provided by (Responsible Party):
AstraZeneca
  Purpose
This study will compare the effects of commercially manufactured exenatide once weekly and exenatide BID in subjects whose type 2 diabetes is managed with diet and exercise alone or with oral antidiabetic medications. The study will examine glycemic control (as measured by HbA1C), safety, and tolerability.

Condition Intervention Phase
Type 2 Diabetes Mellitus Drug: exenatide once weekly Drug: exenatide twice daily Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Randomized, Open-Label, Parallel-Group, Comparator-Controlled, Multicenter Study to Evaluate the Glycemic Effects, Safety, and Tolerability of Exenatide Once Weekly in Subjects With Type 2 Diabetes Mellitus

Primary Outcome Measures:
  • Change in HbA1c From Baseline to Week 24 [ Time Frame: Day 1, Week 24 ]
    Change in HbA1c from baseline (Day 1) to Week 24 [Week 24 - Baseline].


Secondary Outcome Measures:
  • Percentage of Subjects Achieving HbA1c Target of <7% [ Time Frame: Week 24 ]
    Percentages of subjects achieving HbA1c target value of <7% at Week 24.

  • Percentage of Subjects Achieving HbA1c Target of <=6.5% [ Time Frame: Week 24 ]
    Percentages of subjects achieving HbA1c target values of <=6.5% at Week 24.

  • Change in Fasting Plasma Glucose From Baseline to Week 24 [ Time Frame: Day 1, Week 24 ]
    Change in fasting plasma glucose from baseline (Day 1) to Week 24.

  • Percentage of Subjects Achieving Fasting Plasma Glucose Target of <=126 mg/dL [ Time Frame: Week 24 ]
    Percentages of subjects achieving fasting plasma glucose target of <=126 mg/dL at Week 24.

  • Change in Body Weight From Baseline to Week 24 [ Time Frame: Day 1, Week 24 ]
    Change in body weight from baseline (Day 1) to Week 24.

  • Change in Sitting Systolic Blood Pressure From Baseline to Week 24 [ Time Frame: Day 1, Week 24 ]
    Change in systolic blood pressure from baseline (Day 1) to Week 24.

  • Change in Sitting Diastolic Blood Pressure From Baseline to Week 24 [ Time Frame: Day 1, Week 24 ]
    Change in diastolic blood pressure from baseline (Day 1) to Week 24.

  • Change in Total Cholesterol From Baseline to Week 24 [ Time Frame: Day 1, Week 24 ]
    Change in total cholesterol from baseline (Day 1) to Week 24.

  • Change in High-density Lipoprotein (HDL) From Baseline to Week 24 [ Time Frame: Day 1, Week 24 ]
    Change in HDL from baseline (Day 1) to Week 24.

  • Ratio of Triglycerides at Week 24 to Baseline [ Time Frame: Day 1, Week 24 ]
    Ratio of triglycerides (measured in mg/dL) at Week 24 to baseline (Day 1). Log (Postbaseline Triglycerides) - log (Baseline Triglycerides); change from baseline to endpoint is presented as ratio of endpoint to baseline.

  • Assessment on Event Rate of Treatment-emergent Major Hypoglycemic Events [ Time Frame: Day 1 to Week 24 ]
    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 24 ]
    The minor hypoglycemia category included events in which symptoms consistent with hypoglycemia were accompanied by a blood glucose concentration of less than 54 mg/dL prior to treatment and not classified as major hypoglycemia.
