Brief summary: The purpose of this study is to demonstrate bioequivalence (BE) of a 5 mg saxagliptin/1000 mg metformin extended release (XR) fixed-dose combination (FDC) tablet (manufactured in Mt Vernon, Indiana) relative to a coadministered 5 mg Onglyza tablet (saxagliptin, manufactured in Mt Vernon, Indiana) and two 500 mg Glucophage XR tablets (metformin XR, manufactured in Evansville, Indiana) in the fed state in healthy subjects.

Detailed description: This study is designed to evaluate if the FDC tablet of 5 mg saxagliptin/1000 mg metformin extended release (manufactured in Mt Vernon, Indiana) is bioequivalent to the coadministered 5 mg saxagliptin tablet plus 2 x 500 mg Glucophage XR tablets (manufactured in Evansville, Indiana)
