A Study to Characterize the Effect on the Pharmacokinetics of ASP1941 and Sitagliptin When Given Together to Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to evaluate pharmacokinetics, pharmacodynamics and safety following the administration of ASP1941 and sitagliptin in single and multiple doses.

Detailed Description
-----------------
All subjects will be enrolled at one center and confined to the unit for up to 17 days. Subjects will be dosed in the fasting state in one of the four groups.
