* Patients who have taken a tumor necrosis factor alpha (TNFα) inhibitor must have experienced an inadequate response or intolerance to treatment given at an approved dose for at least 12 weeks
* Patients currently taking NSAIDs, cyclooxygenase 2 (COX-2) inhibitors, analgesics, corticosteroids, methotrexate (MTX), leflunomide (LEF), sulfasalazine (SSZ), hydroxychloroquine (HCQ) AND/OR apremilast can be allowed if they fulfill specific requirements prior to study entry
Exclusion Criteria
* Treatment with more than 1 TNFα inhibitor and/or more than 2 additional non-TNFα biological response modifiers, or any interleukin (IL)-17 biological response modifier at any time are excluded
