简要总结
This study is to evaluate the efficacy and safety of ASP015K monotherapy and to evaluate the dose-dependent response of ASP015K in moderate to severe Rheumatoid Arthritis (RA) subjects given ASP015K for 12 weeks.
详细描述
This is a Phase 2b, randomized, double-blind, parallel-group, placebo-controlled, dose-finding, monotherapy, multi-center study with once daily oral ASP015K or matching placebo in subjects with moderate to severe RA, with or without prior antirheumatic medication, and regardless of responsiveness to the medication.
The study is comprised of up to a 4-week Screening period, a 12-week Treatment period and a 4-week Follow-up period.
