The purpose of this study is to evaluate the efficacy of ustekinumab and CNTO 1959 in reducing the signs and symptoms of disease in patients with active rheumatoid arthritis (RA) despite concomitant methotrexate (MTX) therapy and to evaluate the safety of ustekinumab and CNTO 1959 in this population.
This is a randomized (patients assigned to treatment by chance), double-blind (study personnel and patients will not know what treatment is being assigned to patients), multicenter, placebo-controlled (a placebo is a treatment identical in appearance to the study agent, but containing no active ingredient), dose-ranging study. Approximately 250 patients will be randomly assigned to 1 of 5 treatment groups. The maximum length of study participation is 54 weeks, including a 6-week screening period. The end of the study will be the last follow-up visit of the last patient. Study visits and evaluations will occur, and patient safety will be monitored throughout the study.
Placebo: form = solution for injection, route = subcutaneous use, at Weeks 0, 4, then every 8 weeks (Weeks 12, 20, and 28) + MTX (pre-study dose)
Ustekinumab: type = exact number, unit = mg, number = 90, form = solution for injection, route = subcutaneous use, at Weeks 0, 4, then every 8 weeks (Weeks 12, 20, and 28) + MTX (pre-study dose)
Ustekinumab: type = exact number, unit = mg, number = 90, form = solution for injection, route = subcutaneous use, at Weeks 0, 4, then every 12 weeks (Weeks 16 and 28) + MTX (pre-study dose)
CNTO 1959: type = exact number, unit = mg, number = 200, form = powder for solution for injection, route = subcutaneous use, at Weeks 0, 4, then every 8 weeks (Weeks 12, 20, and 28) + MTX (pre-study dose)
CNTO 1959: type = exact number, unit = mg, number = 50, form = powder for solution for injection, route = subcutaneous use, at Weeks 0, 4, then every 8 weeks (Weeks 12, 20, and 28)+ MTX (pre-study dose)
