Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in A1C at Week 24

    A1C is measured as a percent. Thus, this change from baseline reflects the Week 24 A1C percent minus the Week 0 A1C percent.

    Weeks 0-24

Secondary Outcomes (5)

  • Change From Baseline in FPG at Week 24

    Weeks 0-24

  • Change From Baseline in 2-hour Post-meal Glucose (2-hr PMG) at Week 24

    Weeks 0-24

  • Change From Baseline in A1C at Week 104

    Weeks 0-104

  • Change From Baseline in FPG at Week 104

    Weeks 0-104
