What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Daily Insulin Dose at Week 24
Time Frame: Baseline and Week 24
|
Change in daily insulin dose following 24 weeks of therapy (i.e., daily insulin dose at Week 24 minus daily insulin dose at baseline)
|
Baseline and Week 24
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in Hemoglobin A1c (A1C) at Week 24
Time Frame: Baseline and Week 24
|
A1C is measured as the percentage of glycosylated hemoglobin.
Change in A1C following 24 weeks of therapy (i.e., A1C at Week 24 minus A1C at baseline)
|
Baseline and Week 24
|
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24
Time Frame: Baseline and Week 24
|
Change in FPG (before breakfast) following 24 weeks of therapy (i.e., FPG at Week 24 minus FPG at baseline)
|
Baseline and Week 24
|
Percent of Participants Achieving Fasting Glucose Target at Any Time During the Study
Time Frame: Up to 24 weeks
|
The fasting glucose target was defined as 3 consecutive days with a fingerstick glucose of 72 to 100 mg/dL (4.0 - 5.6 mmol/L).
|
Up to 24 weeks
|
Time to Achieve the Fasting Glucose Target
Time Frame: Up to 24 weeks
|
Fasting glucose target 3 consecutive days with a fingerstick glucose of 72 to 100 mg/dL (4.0 - 5.6 mmol/L).
This analysis was the Kaplan-Meier estimated 50th percentile of time (days) to first attainment of target.
