A Study to Assess the Bioavailability of ASP015K

Phase 1

Completed

• Conditions: Healthy
• Interventions: Drug: ASP015K

• Registration Number: NCT01430078
• Lead Sponsor: Astellas Pharma Inc

Brief Summary

The objective of the study is to assess the bioavailability of ASP015K within the gastrointestinal tract.

Detailed Description

Each subject will participate in four separate study periods. In each period, subjects will be admitted to the clinical unit approximately seven hours on the day prior to being given study drug. Subjects will remain at the clinical research unit for the next 24 hours after they have received study drug. Subjects will return to the clinical research unit at 36 and 48 hours after they have received study drug to give blood samples. There will be a minimum of a four day "washout" period, between each study period.

Under certain circumstances, subjects may be asked to return to the clinical research unit for an additional study period.
