? On a stable dose with an unchanged mode of application for at least 4 weeks prior to baseline
? Stable MTX dose of ? 10 mg/week and < the upper limit of the applicable approved local label.
? Subject can also be on stable doses of NSAIDs, sulfasalazine and/or hydroxychloroquine as long as they are also on methotrexate.

? Confirmed hemoglobin < 9 g/dL for males and < 8.5 g/dL for females,
? Absolute neutrophil count (ANC) < 1500/mm3 (or < 1200 cells/µL for subjects of African descent who are black),
? AST or ALT > 1.5 × the upper limit of normal (ULN) or bilirubin ? 3 mg/dL,
? Serum creatinine > 1.5 × the ULN,
? Platelets < 100,000 cells/(mm3) (109/L),
