Primary Outcome Measures:

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

Secondary Outcome Measures:

Change in Body Mass Index (BMI) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Change in BMI from baseline after 24 weeks of treatment (i.e., BMI at week 24 minus BMI at week 0)
Change in Waist-to-hip Ratio [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Waist-to-hip ratio at week 24 compared to waist-to-hip ratio at week 0 (i.e., waist-to-hip ratio at week 24 minus waist-to-hip ratio at week 0). Waist-to-hip ratio equals waist circumference at given time point divided by hip circumference at given timepoint.
Percentage of Patients Experiencing >=5% Weight Loss [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Percentage of exenatide and placebo treated patients experiencing >=5% weight loss after 24 weeks of treatment (i.e., [weight at week 0 minus weight at week 24] divided by weight at week 0 times 100% >=5%)
Change in Total Cholesterol [ Time Frame: 24 weeks ] [ 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)
Change in High Density Lipoprotein (HDL) Cholesterol [ Time Frame: 24 weeks ] [ 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)
Ratio of Endpoint (LOCF) to Baseline for Fasting Triglycerides (Logarithmically Transformed) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Ratio of triglycerides at week 24 compared to triglycerides at week 0 (i.e., triglycerides at week 24 divided by triglycerides at week 0)
Change in Low Density Lipoprotein (LDL) Cholesterol [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Change in LDL cholesterol from baseline following 24 weeks of treatment (i.e., LDL cholesterol at week 24 minus LDL cholesterol at week 0)
Change in Fasting Serum Glucose [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Change in fasting serum glucose from baseline following 24 weeks of treatment (i.e., fasting serum glucose at week 24 minus fasting serum glucose at week 0)
Change in Serum Glucose AUC Levels Following Oral Glucose Tolerance Test (OGTT) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Change in serum glucose AUC following OGTT (week 24 compared to week 0) (i.e., serum glucose AUC at week 24 minus serum glucose AUC at week 0)
Ratio of Endpoint (LOCF) to Baseline for Homeostatic Model Assessment-Beta Cell (HOMA-B) (Logarithmically Transformed) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Ratio of HOMA-B at week 24 to HOMA-B at week 0 (i.e., HOMA-B at week 24 divided by HOMA-B at week 0). HOMA-B is a measure of beta cell function.
Ratio of Endpoint (LOCF) to Baseline for Homeostatic Model Assessment-Insulin Sensitivity (HOMA-S) (Logarithmically Transformed) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Ratio of HOMA-S at week 24 to HOMA-S at week 0 (i.e., HOMA-S at week 24 divided by HOMA-S at week 0). HOMA-S is a measure of insulin sensitivity.
Incidence of Patients That Demonstrate Overt Signs of Diabetes Mellitus Diagnosis [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Number of patients in each treatment group that demonstrate overt signs of diabetes mellitus diagnosis by week 24
Incidence of Patients That Demonstrate Normalization of Impaired Fasting Glucose (IFG) and/or Impaired Glucose Tolerance (IGT) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Number of patients in each treatment group that demonstrate normalization of IFG and/or IGT by week 24
Change in High Sensitivity C-reactive Protein (hsCRP) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Change in hsCRP levels from baseline following 24 weeks of treatment (i.e., hsCRP at week 24 minus hsCRP at week 0)
Change in Glycosylated Hemoglobin (HbA1c) [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
Change in HbA1c from baseline following 24 weeks of treatment (i.e., HbA1c at week 24 minus HbA1c at week 0)
