What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Matsuda Index | Change in peripheral insulin sensitivity was measured by the Matsuda Index. Fasting plasma glucose (FPG) and fasting plasma insulin (FPI) concentrations measured during the oral glucose tolerance test (OGTT) were used to calculate the Matsuda Index. Matsuda Index=10,000/square root [FPG mg/dL x FPI μIU/mL) x (mean glucose mg/dL x mean insulin μIU/mL during OGTT)]. A Matsuda index of <2.5 indicates whole body insulin resistance. A lower Matsuda Index indicates the worst disease state. An increase in the Matsuda Index indicates an improvement in insulin sensitivity (best). A positive change from Baseline indicates improvement and a negative change from Baseline indicates a worsening. | Baseline (Day 1) to Weeks 12 and 24 | 
| Change From Baseline in Adipose Tissue Insulin Resistance (Adipo-IR ) Index | Change in adipose insulin sensitivity was measured by Adipo-IR. Adipo-IR= (Fasting Serum free fatty acid (FFA) mmol/L x FPI μIU/mL). A higher Adipo-IR index indicates the worst disease state. A lower Adipo-IR Index is best. A negative change from Baseline indicates improvement and a positive change from Baseline indicates a worsening. | Baseline (Day 1) to Weeks 12 and 24 |
