Phase 1

Completed

• Conditions: Healthy Subjects; Pharmacokinetics of ASP015K; Pharmacodynamics
• Interventions: Drug: ASP015K; Drug: Placebo

• Registration Number: NCT01364974
• Lead Sponsor: Astellas Pharma Inc

Brief Summary

The objective of this study is to explore safety and tolerability of multiple oral doses of ASP015K in healthy volunteers.

Detailed Description

Subjects will be confined to the clinical research unit for 19 days. Subjects will receive a follow-up phone call to asses safety 1 to 5 days after being discharged from the study.

Subjects will receive study drug twice per day (BID) on days 1 to 13 of the 14 day treatment period, and will receive a single dose of study drug on the morning of day 14 of the treatment period.
