Study of the Pharmacokinetics of ASP1941 and the Effect on Glucose Concentrations in Male and Female Young and Elderly Healthy Adults

A Phase 1, Double-Blind, Placebo-Controlled, Randomized Study to Assess the Pharmacokinetics, Safety and Tolerability of Repeat Oral Dosing of ASP1941 and to Explore the Effect of ASP1941 on Glucose Levels in Healthy Adult Subjects (18 to 45 Years and ≥ 65 Years)

This is a study of the pharmacokinetic profile and safety and tolerability of ASP1941after repeat dosing and the effect of ASP1941 on glucose levels in non elderly and elderly healthy adult male and female subjects.
