Detailed Description:

This study consists of two parts. Part A is a double-blind, placebo controlled single dose escalation study to evaluate the safety and tolerability of single ascending doses of ASP1941. Part B is an open label, crossover design food-effect study to evaluate the effect of fed conditions on the PK of ASP1941.
