• Must have been treated with MTX for at least 3 months prior to randomization, and must be on a stable dose between 7.5 and 25 mg/week (PO or parenteral, not both) for at least 4 weeks prior to randomization. Subjects will be required to maintain their stable dose through Day 28/Week 4 of the study.

• Currently using treatment with DMARDs (other than sulfasalazine, hydroxychloroquine or chloroquine and MTX), including biologics. Previous use is only allowed after adequate washout (4 weeks or 5 half-lives, whichever is longer) prior to randomization.

• Previous treatment with any cell depleting therapies, including investigational agents (eg, CAMPATH, anti-CD4, anti-CD5, anti-CD3, anti-CD19 and anti-CD20) within 6 months of screening.
