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.

Randomized participants who had both baseline and Week 4 assessments.

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.

Randomized participants who had both baseline and Week 4 assessments.

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.

Randomized participants who had both baseline and Week 4 assessments. Last Observation Carried Forward (LOCF).

'Confirmed' = recorded on the hypoglycemia AE case report form with a fingerstick for glucose <= 50 mg/dL and associated symptoms.

Treated participants

Hypoglycemic events are based upon the Saxagliptin Predefined List of Events, which includes hypoglycemia, blood glucose decreased, and hypoglycemic unconsciousness. The Hypoglycemic events occurred in less than 5% of the participants and hence do not appear in the adverse events module.
