Primary Outcome Measures:
- Change From Baseline in A1C at Week 24 [ Time Frame: Weeks 0-24 ]A1C is measured as a percent. Thus, this change from baseline reflects the Week 24 A1C percent minus the Week 0 A1C percent.
Secondary Outcome Measures:
- Change From Baseline in FPG at Week 24 [ Time Frame: Weeks 0-24 ]Change from baseline at Week 24 is defined as Week 24 FPG minus Week 0 FPG.
- Change From Baseline in 2-hour Post-meal Glucose (2-hr PMG) at Week 24 [ Time Frame: Weeks 0-24 ]Change from baseline at Week 24 is defined as Week 24 2-hr PMG minus Week 0 2-hr PMG.
- Change From Baseline in A1C at Week 104 [ Time Frame: Weeks 0-104 ]A1C is measured as a percent. Thus, this change from baseline reflects the Week 104 A1C percent minus the Week 0 A1C percent.
- Change From Baseline in FPG at Week 104 [ Time Frame: Weeks 0-104 ]Change from baseline at Week 104 is defined as Week 104 FPG minus Week 0 FPG.
- Change From Baseline in 2-hr PMG at Week 104 [ Time Frame: Weeks 0-104 ]Change from baseline at Week 104 is defined as Week 104 2-hr PMG minus Week 0 2-hr PMG.
