Description of intervention(s) / exposure
Treatment: Drugs - GLPG0634
Treatment: Drugs - Placebo

Placebo comparator: Placebo - Participants received GLPG0634 matching placebo capsules, orally, once daily (QD) during Weeks 1 to 12 and GLPG0634 100 milligram (mg) QD during Weeks 13 to 24.

Experimental: GLPG0634 50 mg QD - Participants received GLPG0634 50 mg capsules, orally, QD during Weeks 1 to 12. Participants who were responders (having at least 20% improvement on TJC68 and SJC66) remained on 50 mg QD while nonresponders were re-randomized to 100 mg QD during Weeks 13 to 24.

Experimental: GLPG0634 100 mg QD - Participants received GLPG0634 100 mg capsules, orally, QD during Weeks 1 to 24.

Experimental: GLPG0634 200 mg QD - Participants received GLPG0634 200 mg capsules, orally, QD during Weeks 1 to 24.

Summary
Brief 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.
