Summary
This study will evaluate the safety and efficacy of SKI-O-703 compared with placebo, in patients with active rheumatoid arthritis (RA) who have had an inadequate response to conventional synthetic disease-modifying agents. Patients will be randomly assigned to one of 4 groups and will receive one of three doses of SKI-O-703 or placebo, administered orally twice daily for 12 weeks.
