Primary Outcome Measures :
  1. The primary efficacy endpoint is the change from baseline HbA1c measured at 12 weeks after randomization.
  2. HbA1c is measured at Weeks -4, -1, 0, 6, and 12 of comparative treatment. The baseline value is the mean of the Week -1 and Week 0 values.

Secondary Outcome Measures :
  1. Secondary: Efficacy: change in fasting plasma glucose and meal glucose response (2-h postprandial increment in plasma glucose)Fasting plasma glucose measured at Weeks -4, -1, 0, and 12 (the Weeks -1 and 12 measurements will be part of the meal studies)
  2. Meal glucose response measured at Week -1 and at Week 12;
  3. These results for efficacy are measured in the lab using plasma samples collected during clinic visits,
  4. not the subject’s home glucose monitoring results.
  5. Comparison of 24-hour home glucose profiles.
  6. Proportion of subjects with acceptable or good glycemic control (e.g., HbA1c < 8.0% or <7.0%) at the end of treatment, incidence and severity of hypoglycemic episodes, discontinuation rate, change in fasting lipid profile, and change in body weight.
  7. A patient satisfaction and preference questionnaire will be administered at screening, at baseline, during active therapy, and at the end of the study.
