Primary Outcome Measures:
  • HbA1c Change From Baseline at Week 52 [ Time Frame: Baseline and week 52 ] [ Designated as safety issue: No ]
    This co-primary endpoint, change from baseline, reflects the Week 52 HbA1c percent minus the baseline HbA1c percent. Means are treatment adjusted for baseline HbA1c and the number of previous anti-diabetic medications.

  • HbA1c Change From Baseline at Week 104 [ Time Frame: Baseline and week 104 ] [ Designated as safety issue: No ]
    This co-primary endpoint, change from baseline, reflects the Week 104 HbA1c percent minus the baseline HbA1c percent. Means are treatment adjusted for baseline HbA1c and the number of previous anti-diabetic medications.


Secondary Outcome Measures:
  • Body Weight Change From Baseline at Week 52 [ Time Frame: Baseline and week 52 ] [ Designated as safety issue: No ]
    This key secondary endpoint, change from baseline, reflects the Week 52 body weight minus the baseline body weight. Means are treatment adjusted for baseline HbA1c, baseline weight and the number of previous antidiabetic-medications.

  • Body Weight Change From Baseline at Week 104 [ Time Frame: Baseline and week 104 ] [ Designated as safety issue: No ]
    This key secondary endpoint, change from baseline, reflects the Week 104 body weight minus the baseline body weight. Means are treatment adjusted for baseline HbA1c, baseline weight and the number of previous antidiabetic-medications.

  • Incidence of Hypoglycaemic Events up to 52 Weeks [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
    A hypoglycaemic event is defined as patient showing clinical signs suggestive of low blood glucose confirmed by a home blood glucose monitoring (HBGM) of below 55 mg/dl (3.1 mmol/L)

  • Incidence of Hypoglycaemic Events up to 104 Weeks [ Time Frame: Week 104 ] [ Designated as safety issue: No ]
    A hypoglycaemic event is defined as patient showing clinical signs suggestive of low blood glucose confirmed by a HBGM of below 55 mg/dl (3.1 mmol/L)

  • Fasting Plasma Glucose (FPG) Change From Baseline at Week 52 [ Time Frame: Baseline and week 52 ] [ Designated as safety issue: No ]
    This change from baseline reflects the Week 52 FPG minus the Baseline FPG. Means are treatment adjusted for baseline HbA1c, baseline FPG and the number of previous anti-diabetic medications.

  • Fasting Plasma Glucose (FPG) Change From Baseline at Week 104 [ Time Frame: Baseline and week 104 ] [ Designated as safety issue: No ]

If a patient did not have an HbA1c value at week 52 they were considered a failure, so HbA1c >= 7.0%. The logistic regression is treatment adjusted for baseline HbA1c and number of previous anti-diabetic medications.

  • Percentage of Patients With HbA1c <7.0% at Week 104 [ Time Frame: Week 104 ] [ Designated as safety issue: No ]

If a patient did not have an HbA1c value at week 104 they were considered a failure, so HbA1c >= 7.0%. The logistic regression is treatment adjusted for baseline HbA1c and number of previous anti-diabetic medications.

  • Percentage of Patients With HbA1c <6.5% at Week 52 [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
