Primary Endpoints
Hemoglobin A1c (HbA1c) Change From Baseline to Week 52
Baseline to 52 Weeks

Adjusted mean change from baseline in HbA1c achieved with saxagliptin added on to metformin versus glipizide added on to metformin at Week 52 (Per Protocol Analysis Set). HbA1c is a continuous measure, the change from baseline for each participant is calculated as the Week 52 value minus the baseline value.

Secondary Endpoints
Proportion of Participants Reporting at Least One Episode of Any Hypoglycaemic Event Over 52 Weeks
From Baseline to Week 52
Body Weight Change From Baseline to Week 52
Baseline, Week 52 (Last Observation Carried Forward)
