Exclusion Criteria:

• Have received anti-tumor necrosis factor (TNF) agents (eg, infliximab, golimumab, adalimumab, etanercept, or certolizumab pegol) within 3 months of Day 1
• Have a history of tocilizumab (anti-IL-6 receptor) or sirukumab use; have used B-cell depleting therapy (eg, rituximab) within 7 months of Day 1; have used anakinra within 4 weeks of Day 1; have used any other biologic therapy for the treatment of RA within 3 months of Day 1
• Have received intra-articular (IA), intramuscular (IM), intravenous (IV), or topical corticosteroids, including adrenocorticotrophic hormone, during the 4 weeks prior to Day 1
• Have received leflunomide within 24 months of Day 1 and have not undergone a drug elimination procedure, unless the M1 metabolite is measured and is undetectable
