    3. 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.

    4. 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.

    5. Number of Participants With Anti Drug Antibodies [Baseline through 3 Months]
