* Are methotrexate (MTX)-naïve (ie, have not received more than 3 weekly doses of MTX for RA at any time)
* Have active RA as defined by persistent disease activity with at least 4 swollen and 4 tender joints, at the time of screening and baseline, and at least 2 of the following 4 criteria: a) C-reactive protein (CRP) \>=1.5 mg/dL at screening or erythrocyte sedimentation rate (ESR) by Westergren method of \>= 28 mm in the first hour at screening or baseline, b)Morning stiffness of \>= 30 minutes at screening and baseline, c)Bone erosion by x-ray and/or MRI prior to first administration of study agent, d)Anti-cyclic citrullinated peptide (anti-CCP) antibody-positive or rheumatoid factor (RF) positive at screening
* If using oral corticosteroids, must be on a stable dose equivalent to \<= 10 mg of prednisone/day for at least 2 weeks prior to first administration of study agent.
