Outcome Measures

Primary Outcomes (1)

  • Hemoglobin A1C (A1C) at Week 18

    A1C is measured as percent. Thus, this change from baseline reflects the Week 18 A1C percent minus the Week 0 A1C percent. The study hypothesis comparison was between sitagliptin versus placebo.

    Baseline and 18 Weeks

Secondary Outcomes (2)

  • Fasting Plasma Glucose (FPG) at Week 18

    Baseline and 18 Weeks

  • 2-hour Post-meal Glucose (PMG) at Week 18

    Baseline and 18 Weeks
