- Change From Baseline in Body Weight [ Time Frame: Baseline, Week 24 ]Change in body weight from baseline (Week 0) after 24 weeks of treatment (i.e., weight at week 24 minus weight at week 0). Body weight measured in kilograms (k).
- Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 24 [ Time Frame: baseline, Week 24 ]Change in HbA1c from baseline (Week 0) after 24 weeks of treatment (i.e., HbA1c at week 24 minus HbA1c at week 0). HbA1c is measured as percent (%) of hemoglobin.
- Change From Baseline in 6-point Self Monitored Blood Glucose (SMBG) Profile at Week 24 [ Time Frame: baseline, Week 24 ]Change in SMBG at each of 6 time points throughout a day (blood glucose measurements before and 2 hours after the start of the morning, mid-day, and evening meals); week 24 compared to week 0 (i.e., SMBG at week 24 minus SMBG at week 0). Fasting Glucose measured in millimoles per liter (mmol/L).
- Change From Baseline in Waist Circumference at Week 24 [ Time Frame: baseline, Week 24 ]Change in waist circumference from baseline after 24 weeks of treatment (i.e., waist circumference at week 24 minus waist circumference at week 0). Waist measured in centimeters (cm).
- Ratio of Homeostatic Model Assessment-Beta Cell (HOMA-B) at Week 24 to HOMA-B at Baseline [ Time Frame: baseline, Week 24 ]Ratio of HOMA-B at Week 24 to HOMA-B at baseline (Week 0). HOMA-B is a computer solved model used to predict the homeostatic concentrations which arise from varying degrees beta-cell deficiency. HOMA-B allows a quantitative assessment of the contributions of deficient beta cell function to the fasting hyperglycemia. HOMA-B is measured as a percent of the normal population (normal beta cell function = 100%, which is used as a reference in the calculation). The higher the percent the better for the participant.
- Ratio of Homeostatic Model Assessment-Insulin Sensitivity (HOMA-S) at Week 24 to HOMA-S at Baseline [ Time Frame: baseline, Week 24 ]Ratio of HOMA-S at Week 24 to HOMA-S at baseline, week 0. HOMA-S is a computer solved model used to predict the homeostatic concentrations which arise from varying degrees of insulin sensitivity. HOMA-S allows a quantitative assessment of the contributions of insulin sensitivity to the fasting hyperglycemia. HOMA-S is measured as a percent of the normal population (normal insulin sensitivity = 100%, which is used as a reference in the calculation). The higher the percent the better for the participant.
- Change From Baseline in High Density Lipoprotein (HDL) Cholesterol at Week 24 [ Time Frame: baseline, Week 24 ]Change in HDL cholesterol from baseline after 24 weeks of treatment (i.e., HDL cholesterol at week 24 minus HDL cholesterol at week 0). HDL measured as mmol/L.
- Change From Baseline in Low Density Lipoprotein (LDL) Cholesterol at Week 24 [ Time Frame: baseline, Week 24 ]Change in LDL cholesterol from baseline (Week 0) after 24 weeks of treatment (ie., LDL cholesterol at week 24 minus LDL cholesterol at week 0). LDL cholesterol measured in mmol/L
- Change From Baseline in Total Cholesterol at Week 24 [ Time Frame: baseline, week 24 ]Change in total cholesterol from baseline after 24 weeks of treatment (i.e., total cholesterol at week 24 minus total cholesterol at week 0). Total cholesterol measured in mmol/L.
- Ratio of Triglycerides at Week 24 to Triglycerides at Baseline [ Time Frame: baseline, Week 24 ]Ratio of triglyceride levels at Week 24 to triglyceride levels at baseline, Week 0 (ie., triglycerides at Week 24 divided by triglycerides at baseline, Week 0). Triglycerides measured in mmol/L.
- Number of Participants With Hypoglycemic Events During the Study [ Time Frame: Baseline to 24 weeks ]Number of participants experiencing one or more events of hypoglycemia at any point in the study
- Rate of Hypoglycemic Events [ Time Frame: 24 weeks ]Overall rate of hypoglycemia, adjusted for 1 year (ie., events of hypoglycemia per participant per year).
