Dose-finding Study of GLPG0634 as Monotherapy in Active Rheumatoid Arthritis (RA) Participants (DARWIN2)

Summary

* Participants suffering from active rheumatoid arthritis who had an inadequate response to methotrexate were evaluated for improvement of disease activity (efficacy) when taking GLPG0634 as monotherapy (3 different doses - 50 milligram (mg), 100 mg and 200 mg once daily) or matching placebo for 24 weeks. * During the course of the study, patients were also examined for any side effects that could occur (safety and tolerability), and the amount of GLPG0634 present in the blood (Pharmacokinetics) as well as the effects of GLPG0634 on disease- and mechanism of action-related parameters in the blood (Pharmacodynamics) were determined. Also, the effects of different doses of GLPG0634 administration on participants' disability, fatigue and quality of life were evaluated.
