Outcome Measures
Primary Outcome Measures
- Change From Baseline in Haemoglobin A1c (HbA1c) [Baseline, 3 Months]
Least squares (LS) mean was calculated using mixed model repeated measures model (MMRM) with baseline + baseline BMI group + baseline metformin flag + treatment + time + treatment*time as fixed factors.
Secondary Outcome Measures
- Percentage of Participants Achieving HbA1c Target of <7.0% [3 Months]
Percentage of participants achieving HbA1c target of < (less than) 7.0%.
- Change From Baseline in Fasting Blood Glucose (FBG) [Baseline, 3 Months]
LSMean was calculated using MMRM model with baseline + baseline HbA1C group + baseline BMI group + baseline Metformin flag + treatment + time + treatment*time as fixed factors.
- Change From Baseline in Body Weight [Baseline, 3 Months]
LSMean was calculated using MMRM model with baseline + baseline HbA1C group + baseline BMI group + baseline Metformin flag + treatment + time + treatment*time as fixed factors.
- Change From Baseline in Waist Circumference [Baseline, 3 Months]
LSMean was calculated using MMRM model with baseline + baseline HbA1C group + baseline BMI group + baseline Metformin flag + treatment + time + treatment*time as fixed factors.
- Number of Participants With Anti Drug Antibodies [Baseline through 3 Months]
Number of participants with anti drug antibodies.
- Number of Episodes of Total Hypoglycemia Episodes [Baseline through 3 Months]
Number of episodes of total hypoglycemia episodes with plasma glucose <= ( less than or equal to) 54 mg/dL.
