Primary Outcome Measures:
  • Hemoglobin A1c (A1C) Changes From Baseline at Week 24 [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    To compare the change from baseline in HbA1c achieved with each dose of saxagliptin versus placebo in treatment naive subjects with type 2 diabetes who have inadequate glycemic control defined as A1C ≥7.0% and ≤10.0%.

  • A1C Changes From Baseline at Week 24 - Open Label Cohort [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    To compare the change from baseline in HbA1c achieved with each dose of saxagliptin versus placebo in treatment naive subjects with type 2 diabetes who have inadequate glycemic control defined as A1C ≥7.0% and ≤10.0%.


Secondary Outcome Measures:
  • Baseline and Change From Baseline at Week 24 in Fasting Plasma Glucose (FPG) [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
  • Percentage of Participants Achieving Therapeutic Glycemic Response (A1C < 7.0%) at Week 24 [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
  • Baseline and Change From Baseline at Week 24 in Postprandial Glucose (PPG) Area Under the Curve (AUC) [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
  • Baseline and Change From Baseline at Week 24 in Fasting Plasma Glucose (FPG) - Open Label Cohort [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
  • Percentage of Participants Achieving Therapeutic Glycemic Response (A1C < 7.0%) at Week 24 - Open Label Cohort [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
  • Baseline and Change From Baseline at Week 24 in Postprandial Glucose (PPG) Area Under the Curve (AUC) - Open Label Cohort [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]

Detailed Description:

All subjects will participate in a lead-in period, and qualifying subjects will continue into a short-term randomized treatment period. Subjects who complete the short-term period will be eligible to enter the long term extension period. Also, subjects in the short-term period who have an elevated blood sugar that requires additional medication for blood sugar control will be eligible to enter the long-term treatment extension period where they will receive metformin added onto their blinded study medication. Subjects with screening hemoglobin A1c (A1C) > 10.0% and ≤ 12.0%, who otherwise meet all inclusion/exclusion criteria, were eligible to enroll directly into Open-Label Treatment Cohort (Direct Enrollees) and receive open-label saxagliptin 10 mg. Those who completed the short-term period were eligible to enter into the long-term treatment extension period.Saxagliptin dose titration was not permitted.
