Brief Summary

The primary objectives of this study were:

* To assess the effect of a high-fat diet on the pharmacokinetics (PK) of a 0.75 mg single dose of S-888711 orally administered as 0.25 mg tablets in healthy volunteer adults

* To assess the effect of a calcium supplement on the PK of a 0.75 mg single dose of S-888711 orally administered as 0.25 mg tablets in healthy volunteer adults
