  • Percentage of Subjects achieving ACR 70 response [ Time Frame: At each study visit (up to 132 weeks) ] [ Designated as safety issue: No ]
  • Change from baseline in Disease Activity Score using 28 joint count and C Reactive Protein (DAS28-CRP) [ Time Frame: At each study visit (up to 132 weeks) ] [ Designated as safety issue: No ]

Enrollment: 200

Estimated Primary Completion Date: January 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ASP015K group Drug: ASP015K
oral

Detailed Description:

This study is an extension of study RAJ1 conducted as an open-label multicenter study in RA patients who completed study RAJ1.

Patients will receive oral ASP015K once daily (QD) after breakfast. The ASP015K dose can be increased later if the subjects have no safety problems but show lack of efficacy. The dose level will be reconsidered after the results of the dose-setting study (study RAJ1) have been obtained.

Because this study will end at the point in time where the Phase III study begins, the duration of treatment with the study drug will differ depending upon the subject (planned maximum duration of treatment: 132 weeks).
