  3. Change in Heart Rate From Baseline to 24 Week Endpoint [ Time Frame: Baseline, 24 weeks ]
    Heart rate change from baseline is presented as Least Squares Mean (LSMean) with treatment, visit, and their interaction as fixed effects, subject as a random effect, baseline heart rate, age, gender were used as covariates.

  4. Change in Blood Pressure From Baseline to 24 Week Endpoint [ Time Frame: Baseline, 24 weeks ]
    Blood pressure change from baseline is presented as Least Squares Mean (LSMean) with treatment, visit, and their interaction as fixed effects, subject as a random effect, baseline blood pressure, age, gender were used as covariates.

  5. Change in Body Composition Using Dual Energy X-ray Absorptiometry (DXA) From Baseline to 24 Week Endpoint [ Time Frame: Baseline, 24 weeks ]
    Change in body composition (lean body mass and fat mass) was assessed using dual energy x-ray absorptiometry (DXA) and is presented as LSMEAN values with treatment, visit, and their interaction as fixed effects, subject as a random effect, baseline body composition, age, gender were used as covariates.

  6. Change in Waist Circumference From Baseline to 24 Week Endpoint [ Time Frame: Baseline, 24 weeks ]
    Change from baseline to endpoint is presented as LSMEAN with treatment, visit, and their interaction as fixed effects, subject as a random effect, baseline waist circumference, age, gender were used as covariates.

  7. Percentage Change in Waist Circumference From Baseline to 24 Week Endpoint [ Time Frame: Baseline, 24 weeks ]
    Percentage change from baseline to endpoint is presented as LSMEAN with treatment, visit, and their interaction as fixed effects, subject as a random effect, baseline waist circumference, age, gender were used as covariates.

  8. Change in Total Cholesterol From Baseline to 24 Weeks Endpoint [ Time Frame: Baseline, 24 weeks ]

  12. Change From Baseline for Obesity Weight Loss Quality of Life Instrument (OWL-QoL) [ Time Frame: Baseline, 24 weeks ]
    Results presented as Least Squares Mean with treatment, visit, and their interaction as fixed effects, subject as random effect, baseline body mass index used as covariate. OWL-QoL consists of 17 items on scale ranging from 0 (Not at all) to 6 (A very great deal). Before calculating scores, each item is reversed. A single quality of life score is computed by summing each item and transforming this raw score onto standardized scale of 0 (greatest impact) to 100 (lowest impact) using formula: score = [(sum of component items score (minus) lowest possible score/ possible raw score range)*100].

  13. Change From Baseline in Vitality Scale of Medical Outcomes Short Form - 36 (SF-36) Scale [ Time Frame: Baseline, 24 weeks ]
    Vitality change from baseline is presented as Least Squares Mean (LSMean) with treatment, visit, and their interaction as fixed effects, subject as a random effect, baseline body mass index was used as covariate. SF-36 is a self-reported questionnaire that consists of 36 questions covering 8 health domains including vitality. The vitality domain results are presented. The vitality domain is scored by summing the individual items and transforming the scores into a 0 to 100 scale, with higher scores indicating better health status or functioning.

  14. Change in Glycated Hemoglobin A1c (HbA1c) From Baseline [ Time Frame: Baseline, 24 weeks ]
    Analysis of change in HbA1c was not conducted due to an inadequate number of samples.

  15. Change in Fasting Glucose From Baseline to 24 Weeks Endpoint [ Time Frame: Baseline, 24 weeks ]
    Analysis of change in fasting glucose was not conducted due to an inadequate number of samples.

  16. Change in Fasting Insulin From Baseline to 24 Weeks Endpoint [ Time Frame: Baseline, 24 weeks ]
    Analysis of change in fasting insulin was not conducted due to an inadequate number of samples.

  17. Change in Insulin Resistance From Baseline to 24 Weeks Endpoint [ Time Frame: Baseline, 24 weeks ]
    Analysis of change in insulin resistance was not conducted due to an inadequate number of samples.

  18. Pharmacokinetics: Area Under the Concentration Time Curve (AUC) [ Time Frame: 4 weeks, 12 weeks, and 24 weeks ]
    Analysis of AUC was not conducted due to an inadequate number of samples collected.

  19. Pharmacokinetics: Maximum Concentration (Cmax) [ Time Frame: 4 weeks, 12 weeks, and 24 weeks ]
    Analysis of Cmax was not conducted due to an inadequate number of samples collected.
