Change From Baseline in Hemoglobin A1C (A1C) at Week 12
大体时间:Baseline to Week 12
|
Baseline was defined as the last value collected prior to the first dose of double-blind study medication.
Post-baseline Least Square (LS) mean values were obtained from mixed-effects model repeated measures (MMRM) model with treatment, randomization strata of insulin delivery method (continuous subcutaneous insulin infusion [CSII] or multiple daily injection [MDI]), time (study week), and a treatment-by-time interaction as fixed categorical effects, and baseline A1C-by-time interaction as a covariate.

Change From Baseline to Week 12 in 2-Hour Postprandial Glucose (PPG) Following the Standardized Mixed Meal
大体时间:Baseline, Week 12
|
A 2-hour PPG sample (plasma) was obtained 2-hours after a standardized Mixed Meal at Baseline (Day 1) and at the visit at Week 12. Post-Baseline LS mean was obtained from analysis of covariance (ANCOVA) model with treatment, randomization strata of insulin delivery method (CSII, MDI) as fixed categorical effects, and baseline postprandial glucose as a covariate.

Baseline was defined as the last value collected prior to the first dose of double-blind study medication.
Post-Baseline LS mean was obtained from MMRM model with treatment, randomization strata of insulin delivery method (CSII, MDI), time (study week), and a treatment-by-time interaction as fixed categorical effects, and baseline weight-by-time interaction as a covariate.

大体时间:Baseline, Week 12
|
Urine was collected over 24 hours to measure Urinary Glucose Excretion at baseline, and at the end of the 12-week treatment.
Post-Baseline LS mean was obtained from ANCOVA model with treatment, randomization strata of insulin delivery method (CSII, MDI) as fixed categorical effects, and Baseline urinary glucose excretion as a covariate.
