Resumen

The purpose of this study is to evaluate clinical effectiveness and safety of golimumab with methotrexate (MTX) in the treatment of rheumatoid arthritis (RA) when compared to MTX alone.

Descripción detallada

This is a randomized (study medication is assigned by chance), double-blind (neither physician nor participants knows the treatment that the participant receives), placebo-controlled (an inactive substance is compared with a medication to test whether the medication has a real effect in a clinical study), multicenter, 2-arm (2 groups) study of golimumab in participants with active RA despite concurrent MTX therapy. Approximately 564 participants will be randomly allocated to 1 of 2 treatment groups in a 2:1 ratio ie, Group 1(approximately 376 participants will receive golimumab + MTX) and Group 2 (approximately 188 participants will receive MTX + placebo). Total duration of study for each participant is 112 weeks. Safety will be evaluated by assessment of adverse events, tuberculosis testing and blood testing.
