Outcome Measures
Primary Outcome Measures
- Percentage of Participants With A1C <7.0% at Week 24 and No Episode of Severe Hypoglycemia and No Episode of Diabetic Ketoacidosis (DKA) After Randomization [Week 24]
The primary composite endpoint included blood samples for the assessment of Hemoglobin A1C to determine the participants with a value <7.0%. A central blinded adjudication process determined whether participants experienced either DKA or Severe Hypoglycemia.
Secondary Outcome Measures
- Change From Baseline in A1C [Baseline to Week 24]
Baseline value was defined as the last value collected prior to the first dose of double-blind study medication. Least Squares (LS) means were obtained from a mixed-effects model for repeated measures (MMRM) model including all available post baseline data. A negative change from Baseline (a lower AIC value at Week 24) indicates an improvement.
- Absolute Change From Baseline in Body Weight [Baseline to Week 24]
Baseline value was defined as the last value collected prior to the first dose of double-blind study medication. LS means were obtained from MMRM model. A negative change from Baseline indicates a loss in body weight from Baseline to Week 24.
- Change From Baseline in Systolic Blood Pressure (SBP) in the Subset of Participants With Baseline SBP >=130 Millimeter of Mercury (mmHg) [Baseline to Week 16]
An automatic sphygmomanometer was used with instructions on blood pressure measurements to allow for standardization. Week 16 was used because the protocol required Investigators to keep participant's hypertensive medications stable between Baseline and Week 16, unless a change was required for safety reasons. Baseline was defined as the last value collected prior to the first does of double-blind study medication. LS means were obtained from MMRM model including all available post baseline values. A negative change indicates a decrease in SBP between Baseline and Week 16.
- Percent Change From Baseline in Mean Daily Bolus Insulin Dose [Baseline to Week 24]
The mean bolus insulin dose in international units/day (IU/day) for Week 24 was the average over the 3 to 5 days prior to the Week 24 visit. The Baseline value was defined as the last value collected prior to the first dose of double-blind study medication. LS means were obtained from MMRM model including all available post Baseline values. A negative percent change from Baseline indicated a reduction in the amount of bolus insulin used and a positive percent change from Baseline indicated an increase in the amount of bolus insulin used between Baseline and Week 24.

Comments | Testing according to the hierarchical procedure. Post-Baseline LS means and p-values were obtained from MMRM model with treatment, randomization stratum of BMI at Screening (<25 kg/m2, >=25 kg/m2), randomization stratum of Week -2 A1C (<=9.0%, >9.0%), randomization stratum of use of CSII at Screening (yes, no), time (study week), and a treatment-by- time interaction as fixed categorical effects, and Baseline SBP-by-time interaction as a covariate. | |

Title | Percent Change From Baseline in Mean Daily Bolus Insulin Dose |
---|---|
Description | The mean bolus insulin dose in international units/day (IU/day) for Week 24 was the average over the 3 to 5 days prior to the Week 24 visit. The Baseline value was defined as the last value collected prior to the first dose of double-blind study medication. LS means were obtained from MMRM model including all available post Baseline values. A negative percent change from Baseline indicated a reduction in the amount of bolus insulin used and a positive percent change from Baseline indicated an increase in the amount of bolus insulin used between Baseline and Week 24. |
Time Frame | Baseline to Week 24 |
