Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline in Mean Glycosylated Hemoglobin (HbA1c) at Week 26 Change from baseline in glycosylated hemoglobin (HbA1c) over 26 weeks, Last Observation Carried Forward. visit 5(week 0) and visit 14(week 26) No
Secondary Change From Baseline in Insulin Resistance Based on Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) Change from Baseline in Insulin Resistance based on homeostasis model assessment of insulin resistance (HOMA-IR) at week 26, Last Observation Carried Forward (LOCF). The HOMA-IR is the the product of the blood Glucose and Insulin levels, divided by a constant. HOMA-IR is expressed as the following: HOMA-IR = fasting serum insulin (µU/ml) × fasting plasma glucose (mmol/l) / 22.5 [visit 5(week 0) and visit 14(week 26)] No
