Effect on Weight Loss of Exenatide Versus Placebo - Full Text View

Purpose

This trial is designed to compare the effects of twice-daily exenatide and twice-daily placebo on weight loss. This trial will evaluate overweight and obese subjects with type 2 diabetes who have inadequate glycemic control with metformin, sulfonylurea, or metformin plus a sulfonylurea. Subjects will be treated with exenatide or placebo in addition to their current oral antidiabetes agent regimen and participate in a lifestyle modification program.

Primary Outcome Measures:

Change From Baseline in Body Weight [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
Change in body weight from baseline (Week 0) after 24 weeks of treatment (i.e., weight at week 24 minus weight at week 0). Body weight measured in kilograms (k).

Secondary Outcome Measures:

Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 24 [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Change in HbA1c from baseline (Week 0) after 24 weeks of treatment (i.e., HbA1c at week 24 minus HbA1c at week 0). HbA1c is measured as percent (%) of hemoglobin.
Change From Baseline in 6-point Self Monitored Blood Glucose (SMBG) Profile at Week 24 [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Change in SMBG at each of 6 time points throughout a day (blood glucose measurements before and 2 hours after the start of the morning, mid-day, and evening meals); week 24 compared to week 0 (i.e., SMBG at week 24 minus SMBG at week 0). Fasting Glucose measured in millimoles per liter (mmol/L).
Change From Baseline in Waist Circumference at Week 24 [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Change in waist circumference from baseline after 24 weeks of treatment (i.e., waist circumference at week 24 minus waist circumference at week 0). Waist measured in centimeters (cm).
Ratio of Homeostatic Model Assessment-Beta Cell (HOMA-B) at Week 24 to HOMA-B at Baseline [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Ratio of HOMA-B at Week 24 to HOMA-B at baseline (Week 0). HOMA-B is a computer solved model used to predict the homeostatic concentrations which arise from varying degrees beta-cell deficiency. HOMA-B allows a quantitative assessment of the contributions of deficient beta cell function to the fasting hyperglycemia. HOMA-B is measured as a percent of the normal population (normal beta cell function = 100%, which is used as a reference in the calculation). The higher the percent the better for the participant.
Ratio of Homeostatic Model Assessment-Insulin Sensitivity (HOMA-S) at Week 24 to HOMA-S at Baseline [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Ratio of HOMA-S at Week 24 to HOMA-S at baseline, week 0. HOMA-S is a computer solved model used to predict the homeostatic concentrations which arise from varying degrees of insulin sensitivity. HOMA-S allows a quantitative assessment of the contributions of insulin sensitivity to the fasting hyperglycemia. HOMA-S is measured as a percent of the normal population (normal insulin sensitivity = 100%, which is used as a reference in the calculation). The higher the percent the better for the participant.
Change From Baseline in High Density Lipoprotein (HDL) Cholesterol at Week 24 [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Change in HDL cholesterol from baseline after 24 weeks of treatment (i.e., HDL cholesterol at week 24 minus HDL cholesterol at week 0). HDL measured as mmol/L.
Change From Baseline in Low Density Lipoprotein (LDL) Cholesterol at Week 24 [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Change in LDL cholesterol from baseline (Week 0) after 24 weeks of treatment (ie., LDL cholesterol at week 24 minus LDL cholesterol at week 0). LDL cholesterol measured in mmol/L
Change From Baseline in Total Cholesterol at Week 24 [ Time Frame: baseline, week 24 ] [ Designated as safety issue: No ]
Change in total cholesterol from baseline after 24 weeks of treatment (i.e., total cholesterol at week 24 minus total cholesterol at week 0). Total cholesterol measured in mmol/L.
Ratio of Triglycerides at Week 24 to Triglycerides at Baseline [ Time Frame: baseline, Week 24 ] [ Designated as safety issue: No ]
Ratio of triglyceride levels at Week 24 to triglyceride levels at baseline, Week 0 (ie., triglycerides at Week 24 divided by triglycerides at baseline, Week 0). Triglycerides measured in mmol/L.
Number of Participants With Hypoglycemic Events During the Study [ Time Frame: Baseline to 24 weeks ] [ Designated as safety issue: No ]
Number of participants experiencing one or more events of hypoglycemia at any point in the study
Rate of Hypoglycemic Events [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Overall rate of hypoglycemia, adjusted for 1 year (ie., events of hypoglycemia per participant per year).
