Study To Evaluate 24 Hour Blood Sugar Control (24-hour Mean Weighted Glucose) In Subjects That Are Taking Saxagliptin 5 mg Added Onto Metformin XR 1500 XR mg Compared To Subjects Taking Metformin XR 1500 mg Up-titrated To Metformin XR 2000 mg - Full Text View

Purpose

The purpose of this study was to compare effect of Saxagliptin as add-on to Metformin on 24-hour mean weighted glucose (MWG) to the effect of uptitrating Metformin in subjects with T2DM inadequately controlled on metformin alone.

Primary Outcome Measures:

Change From Baseline in 24-Hour Mean Weighted Glucose (MWG) at Week 4 [ Time Frame: Baseline, Week 4 ] [ Designated as safety issue: No ]
Adjusted mean change from baseline in MWG achieved with saxagliptin 5 mg plus metformin XR versus placebo plus metformin XR at Week 24. MWG was calculated as the area under the curve (AUC) for the full 24 hours expressed as average mg/dL. Glucose measurements were collected 30 minutes before and just prior to each meal (0 minutes) and 30, 60, 120, and 180 minutes after each meal (with 1 additional measurement at 240 minutes after the evening meal), midnight, 3 AM, and at end-of-domicile visit 24 hours after the first measurement. Mean change from baseline was adjusted for baseline value.

Secondary Outcome Measures:

Change From Baseline to Week 4 in 2-hour Postprandial Glucose (PPG) (2 Hours After the Evening Meal) [ Time Frame: Baseline, Week 4 ] [ Designated as safety issue: No ]
Adjusted mean change from baseline in 2-hour postprandial (after mealtime) plasma glucose two hours after start of the evening meal during 24-hour domicile visits evaluated both at pre-randomization (baseline) and at Week 4. Mean change from baseline was adjusted for baseline value.
Change From Baseline Fasting Plasma Glucose (FPG) at Week 4, Obtained Immediately Before the Morning Meal [ Time Frame: Baseline, Week 4 ] [ Designated as safety issue: No ]
FPG measurements were done at baseline, day 14 and 28. At baseline and day 28, the FPG value=plasma glucose value collected 30 minutes prior to the morning meal during the domicile visit.
