- HbA1c Change From Baseline at Week 12 [ Time Frame: Baseline and week 12 ]HbA1c is measured as a percentage. Thus, this change from baseline reflects the Week 12 HbA1c percent minus the HbA1c percent baseline value. Means are treatment adjusted for baseline HbA1c.
- Percentage of Patients With HbA1c<=7.0% at Week 12 [ Time Frame: week 12 ]Descriptive calculation of Patients with HbA1c <= 7.0% at Week 12.
- Fasting Blood Plasma Glucose Level (FPG) Change From Baseline at Week 12 [ Time Frame: Baseline and week 12 ]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.
