A Study of ASP1585 to Evaluate the Bioequivalence Between ASP1585 Granules and ASP1585 Capsules

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the bioequivalence between ASP1585 granules and ASP1585 capsules after repeated oral administration of ASP1585 granules or ASP1585 capsules under open-label conditions in non-elderly healthy male subjects. In addition, the safety of these products is assessed.
