NCT00917267

  Purpose

Previous studies have suggested that a once-weekly formulation of exenatide may provide sustained glycemic control. These previous studies of exenatide once weekly have been conducted in non-Asian populations, so this study has been developed to support the local regulatory requirements of China, Korea, Japan, India, and Taiwan.


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

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Comparator-Controlled Study to Examine the Effects of Exenatide Once-Weekly Injection on Glucose Control (HbA1c) and Safety in Asian Subjects With Type 2 Diabetes Mellitus Managed With Oral Antidiabetic Medications

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 Targets <=7% at Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Percentage of patients achieving HbA1c <=7% at Week 26 (for patients with HbA1c >7% at baseline).

  • Percentage of Patients Achieving HbA1c Targets <=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 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 from baseline to Week 26.

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

  • Change in High-Density Lipoprotein (HDL) From Baseline to Week 26 [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Change in HDL from baseline to Week 26.

  • Ratio of Triglycerides (TG) at Week 26 to Baseline [ Time Frame: Baseline, Week 26 ] [ Designated as safety issue: No ]
    Ratio of TG (measured in mg/dL) at Week 26 to baseline. Log(Post-baseline TG) - log(Baseline TG); change from baseline to Week 26 is presented as ratio of Week 26 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 and diastolic blood pressure from baseline to Week 26.

  • Assessment of Event Rate of Treatment-emergent Hypoglycemic Events [ 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 sign or symptom associated with hypoglycemia that is either self-treated by the patient or resolves on its own AND has a concurrent finger stick blood glucose <3.0 mmol/L (54 mg/dL) and not classified as major hypoglycemia. Event rate per subject year was calculated for each subject: (number of events observed from a subject/exposure from a subject)*365.25 where exposure = last post-baseline visit date - baseline visit date. Mean and Standard Error were then derived from ITT.
