Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent Change From Baseline in Total Daily Bolus Amount of Exogenous Insulin Required Calculated Over Days 3 to 27 (Treatment Outpatient Period)
Time Frame: Baseline, Day 3 to Day 27
|
Baseline was calculated as the mean value from Day -6 to -2 for Expansion groups and from Day -6 to Day -3 for Pioneer Group.
Percent mean change from baseline was calculated as 100*(sum [each daily value - baseline]/number of assessments)/baseline over Days 3 to 27.
Least squares (LS) Means and confidence interval (CI) for the Expansion groups were based on an analysis of covariance (ANCOVA) model with covariates of baseline mean total bolus insulin, treatment group, factor used to stratify the randomization (screening A1C <= 8%, > 8%), and random effect of participant*treatment group.
LS Means and CI for the Pioneer Group were based on the arithmetic treatment mean.

Baseline, Day 3 to Day 27

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent Mean Change From Baseline in Daily Bolus Amount of Exogenous Insulin Required at Each Meal Calculated Over Days 3 to 27 (Treatment Outpatient Period)
Time Frame: Baseline, Day 3 to Day 27
|
Baseline was calculated as the mean value from Day -6 to -2 for Expansion groups and from Day -6 to Day -3 for Pioneer Group.
Percent mean change from baseline was calculated as 100*(sum [each daily value - baseline] / number of assessments)/baseline over Days 3 to 27.
Percent change was calculated and is presented separately for each meal: i.e., breakfast, lunch and dinner.
LS Means and CI for the Expansion groups were based on an ANCOVA model .
LS Means and CI for the Pioneer Group were based on the arithmetic treatment mean.
|
Baseline, Day 3 to Day 27
|
Percent Change From Baseline in Total Daily Amount of Exogenous Insulin (Total Daily Bolus + Total Daily Basal) Required Calculated Over Days 3 to 27 (Treatment Outpatient Period)
Time Frame: Baseline, Day 3 to Day 27
|
Baseline was calculated as the mean value from Day -6 to -2 for Expansion groups and from Day -6 to Day -3 for Pioneer Group.
Percent mean change from baseline was calculated as 100*(sum [each daily value - baseline]/ number of assessments)/baseline over Days 3 to 27.
LS Means and CI for the Expansion groups were based on an ANCOVA model.
LS Means and CI for the Pioneer Group were based on the arithmetic treatment mean.
|
Baseline, Day 3 to Day 27
|
Change From Baseline in Fasting Plasma Glucose (FPG) at Day 29
Time Frame: Baseline, Day 29
|
Baseline was defined as the last non-missing assessment prior to first dose of study drug.
Change in FPG was calculated by subtracting baseline value from Day 29 value.
LS Means and CI for the Expansion groups were based on a linear mixed repeated measures model.
|
Baseline, Day 29
|
Change From Day 1 in 3-hour Plasma Glucose AUC (AUC0-3 h) Following a Mixed Meal Tolerance Test (MMTT) at Day 29: Expansion Groups
Time Frame: Prior to start of mixed meal and 30, 60, 90, 120 and 180 min post start of mixed meal, on Day 1 and Day 29
|
A MMTT with frequent blood sample collection and with urine collection was performed on Day 1 and Day 29.
Participants fasted (with the exception of water or non-caffeinated, calorie-free beverages) for at least 8 hours before the start of the MMTT and until the final blood sample was collected.
Study drug was to be given within 15 minutes before liquid "Boost® Original" breakfast.
The area under the plasma concentration-time curve (AUC) from time-zero to 3h postdose on Day 1 and Day 29 was calculated using the linear-up/log-down trapezoidal rule.
Change was calculated by subtracting Day 1 value from Day 29 value.
LS Means and CI were based on a linear mixed model.
|
Prior to start of mixed meal and 30, 60, 90, 120 and 180 min post start of mixed meal, on Day 1 and Day 29
|
Change From Baseline in Percent Time Per Day Spent in Euglycemic Range (>=70 and <=180 mg/dL) Over Days 3 to 27 (Treatment Outpatient Period) Based on Continuous Glucose Monitoring
Time Frame: Baseline, Day 3 to Day 27
|
Baseline was calculated as the mean value from Day -6 to -2 for Expansion groups and from Day -6 to Day -3 for Pioneer Group.
Change in percent time per day spent in euglycemic range was calculated by subtracting baseline value from Day 29 value.
LS Means and CI for the Expansion groups were based on a mixed model.
LS mean and CI for the Pioneer Group were based on the arithmetic treatment mean.
|
Baseline, Day 3 to Day 27
|
Change From Day 1 in 3-hour Urinary Glucose Excretion Following a Mixed Meal Tolerance Test (MMTT) to Day 29: Expansion Groups
Time Frame: From 15 minutes before start of mixed meal until 180 min post start of mixed meal, on Day 1 and Day 29
|
A MMTT with frequent blood sample collection and with urine collection was performed on Day 1 and Day 29.
Participants fasted (with the exception of water or non-caffeinated, calorie-free beverages) for at least 8 hours before the start of the MMTT and until the final blood sample was collected.
Study drug was to be given within 15 minutes before liquid "Boost® Original" breakfast.
Participants were asked to void immediately before blood sample 15 minutes before start of mixed meal and immediately after the 180-minute (3 hour) blood sample was collected, and all urine between the -15 minute and post-180-minute time points was collected for urine glucose calculation.
Change was calculated by subtracting Day 1 value from Day 29 value.
LS Means were based on a linear mixed model.
