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)
