Percentage Change in Waist Circumference From Baseline to 24 Week Endpoint	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.	Baseline, 24 weeks
Change in Total Cholesterol From Baseline to 24 Weeks Endpoint		Baseline, 24 weeks
Change in High-density Lipoprotein Cholesterol (HDL-C) From Baseline to 24 Weeks Endpoint		Baseline, 24 weeks

Change From Baseline for Obesity Weight Loss Quality of Life Instrument (OWL-QoL)	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].	Baseline, 24 weeks

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.	Baseline, 24 weeks
Change in Glycated Hemoglobin A1c (HbA1c) From Baseline	Analysis of change in HbA1c was not conducted due to an inadequate number of samples.	Baseline, 24 weeks
Change in Fasting Glucose From Baseline to 24 Weeks Endpoint	Analysis of change in fasting glucose was not conducted due to an inadequate number of samples.	Baseline, 24 weeks
Change in Fasting Insulin From Baseline to 24 Weeks Endpoint	Analysis of change in fasting insulin was not conducted due to an inadequate number of samples.	Baseline, 24 weeks
Change in Insulin Resistance From Baseline to 24 Weeks Endpoint	Analysis of change in insulin resistance was not conducted due to an inadequate number of samples.	Baseline, 24 weeks
Pharmacokinetics: Area Under the Concentration Time Curve (AUC)	Analysis of AUC was not conducted due to an inadequate number of samples collected.	4 weeks, 12 weeks, and 24 weeks
Pharmacokinetics: Maximum Concentration (Cmax)	Analysis of Cmax was not conducted due to an inadequate number of samples collected.	4 weeks, 12 weeks, and 24 weeks
