Primary Outcome Measures:

HbA1c Change From Baseline at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 24 HbA1c percent minus the baseline HbA1c percent. Means are treatment adjusted for baseline HbA1c and previous anti-diabetic medication.

Secondary Outcome Measures:

HbA1c Change From Baseline at Week 6 [ Time Frame: Baseline and week 6 ] [ Designated as safety issue: No ]
HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 6 HbA1c percent minus the baseline HbA1c percent. Means are treatment adjusted for baseline HbA1c and previous anti-diabetic medication.
HbA1c Change From Baseline at Week 12 [ Time Frame: Baseline and week 12 ] [ Designated as safety issue: No ]
HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 12 HbA1c percent minus the baseline HbA1c percent. Means are treatment adjusted for baseline HbA1c and previous anti-diabetic medication.
HbA1c Change From Baseline at Week 18 [ Time Frame: Baseline and week 18 ] [ Designated as safety issue: No ]
HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 18 HbA1c percent minus the baseline HbA1c percent. Means are treatment adjusted for baseline HbA1c and previous anti-diabetic medication.
FPG Change From Baseline at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
This change from baseline reflects the Week 24 FPG minus the baseline FPG. Means are treatment adjusted for baseline HbA1c, baseline FPG and previous anti-diabetic medication.
FPG Change From Baseline at Week 6 [ Time Frame: Baseline and week 6 ] [ Designated as safety issue: No ]
This change from baseline reflects the Week 6 FPG minus the baseline FPG. Means are treatment adjusted for baseline HbA1c, baseline FPG and previous anti-diabetic medication.
FPG Change From Baseline at Week 12 [ Time Frame: Baseline and week 12 ] [ Designated as safety issue: No ]
This change from baseline reflects the Week 12 FPG minus the baseline FPG. Means are treatment adjusted for baseline HbA1c, baseline FPG and previous anti-diabetic medication.
FPG Change From Baseline at Week 18 [ Time Frame: Baseline and week 18 ] [ Designated as safety issue: No ]
This change from baseline reflects the Week 18 FPG minus the baseline FPG. Means are treatment adjusted for baseline HbA1c, baseline FPG and previous anti-diabetic medication.
Percentage of Patients With HbA1c <7.0% at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
The percentage of patients with an HbA1c value below 7.0% at week 24 was calculated for each treatment arm. If a patient did not have an HbA1c value at week 24 they were considered a failure, so HbA1c >= 7.0%. Only patients with baseline HbA1c >= 7%
Percentage of Patients With HbA1c<7.0% at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
The percentage of patients with an HbA1c value below 7.0% at week 24 was calculated for each treatment arm. If a patient did not have an HbA1c value at week 24 they were considered a failure, so HbA1c >= 7.0%.
Percentage of Patients With HbA1c <6.5% at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
The percentage of patients with an HbA1c value below 6.5% at week 24 was calculated for each treatment arm. If a patient did not have an HbA1c value at week 24 they were considered a failure, so HbA1c >= 6.5%. Only patients with baseline HbA1c >= 6.5%.
Percentage of Patients With HbA1c<6.5% at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
The percentage of patients with an HbA1c value below 6.5% at week 24 was calculated for each treatment arm. If a patient did not have an HbA1c value at week 24 they were considered a failure, so HbA1c >= 6.5%.
Percentage of Patients With HbA1c Lowering by 0.5% at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
The percentage of patients with an HbA1c reduction from baseline >= 0.5% at week 24 was calculated for each treatment arm. If a patient did not have an HbA1c value at week 24 they were considered a failure, so HbA1c reduction less than 0.5%.
Adjusted Means for 2h Post Prandial Blood Glucose (PPG) Change From Baseline at Week 24 [ Time Frame: Baseline and week 24 ] [ Designated as safety issue: No ]
This change from baseline reflects the Week 24 2h PPG minus the baseline 2h PPG. Means are treatment adjusted for baseline HbA1c, baseline PPG and previous anti-diabetic medication.
