Inclusion Criteria

To be eligible for participation, patients must meet all of these criteria:
1. Active rheumatoid arthritis (RA);
2. Ongoing treatment with an adequate and stable dose of methotrexate;
3. In the opinion of the investigator, at least one approved TNF-inhibiting biologic agent administered in accordance with its labeling recommendations was inadequately
effective and/or not tolerated.
4. All other inclusion criteria.
Active Rheumatoid Arthritis:
1. Meet the ACR classification criteria for RA
2. Must have active disease at both screening and baseline, as defined by
having both:
a. =6 tender/painful joints on motion (out of 68 joints assessed); and; b. =6 swollen joints (out of 66 joints assessed).
3. Must also have active disease, as defined by one of the following criteria at screening:
a. Erythrocyte sedimentation rate (ESR) (Westergren method) >28 mm/hr; or b. C-reactive protein (CRP) >7 mg/L in the central laboratory.
4. Must meet Class I, II or III of the ACR 1991 Revised Criteria for Global Functional
Status in RA.
Background Methotrexate:
1. Must have taken oral or parenteral methotrexate continuously for at least 4 months prior to the first dose of study medication and be on a stable dose of 7.5 mg to 25 mg weekly, for at least 6 weeks prior to the first dose of study medication. Stable weekly doses less than 15 mg are allowed only in the presence of intolerance to or toxicity from higher doses or where higher doses would violate the local label. Doses higher than 25 mg weekly are not permitted under any circumstances.
2. Patients should be on an adequate and stable dose of folic acid (not less than 5 mg weekly, unless higher doses would violate the local label) for at least 4 weeks prior to the first dose of study medication.
Also:
1. Evidence of a signed and dated informed consent document.
2. Must be at least 18 years of age.
3. Sexually active women of childbearing potential and men whose partners are women of childbearing potential are required to use adequate contraceptive methods during participation in this study.
4. No evidence of active or latent or inadequately treated infection with Mycobacterium tuberculosis (TB) as described in the protocol
5. For traditional DMARDS, the following minimum washout criteria apply:
• Minocycline, Penicillamine, Sulfasalazine: must have been discontinued for 4 weeks prior to the first dose of study drug.
• Leflunomide (Arava®) must have been discontinued 8 weeks prior to the first dose of study drug if no elimination procedure is followed. Alternately, it should have been discontinued with the specified elimination procedure at least 4 weeks prior to the first dose of study drug.
• Auranofin (Ridaura®), Injectable Gold (aurothiglucose or aurothiomalate): must have been discontinued for 8 weeks prior to first dose of study drug.
• Antimalarials (Hydroxychloroquine, Chloroquine): Antimalarials will be allowed in this study. If discontinued, they must be discontinued for 4 weeks prior to the first dose of study drug. If continued, the dose must be stable for at least 8 weeks prior to first dose of study drug.
6. Biologic Response Modifiers. All must be discontinued for entry into this study:
• Anakinra (Kineret®), Enbrel (Etanercept®), Golimumab (Simponi TM):
Discontinued for 4 weeks prior to the first dose of study drug;
• Adalimumab (Humira®): Discontinued for 6 weeks prior to first dose of study
drug;
• Infliximab (Remicade®): Discontinued for 8 weeks prior to the first dose of study

Exclusion Criteria

Patients presenting with any of the following will not be included in the study:
1. Any prior treatment with non B lymphocyte-selective lymphocyte depleting agents/therapies, such as alemtuzumab (Campath®) OR alkylating agents (eg, cyclophosphamide or chlorambucil) OR total lymphoid irradiation, etc. Patients who have received rituximab or other selective B lymphocyte depleting agents (including experimental agents) are eligible if they have not received such therapy for at least 1 year prior to study baseline and have normal CD 19/20+ counts by FACS analysis.
2. Pregnant or lactating females.
3. Blood dyscrasias including confirmed:
- Hemoglobin <9 g/dL or Hematocrit <30%;
- White blood cell count <3.0 x 10^9/L;
- Absolute neutrophil count <1.2 x 10^9/L;
- Platelet count <100 x 10^9/L.
4. Estimated GFR less than 40 ml/min based on Cockcroft-Gault calculation.
5. AST or ALT more than 1.5 times the upper limit of normal at screening visit.
6. Current or recent history of uncontrolled clinically significant renal, hepatic, hematological, gastrointestinal, endocrine, metabolic, pulmonary, cardiac, or neurological disease.
7. History of any other autoimmune rheumatic disease other than Sjogren’s
syndrome.
8. History of an infected joint prosthesis at any time, with the prosthesis still in situ.
9. History of any lymphoproliferative disorder, such as Epstein Barr Virus (EBV) related lymphoproliferative disorder, history of lymphoma, leukemia, or signs and symptoms suggestive of current lymphatic disease.
10. History of infection requiring hospitalization, parenteral antimicrobial therapy, or as otherwise judged clinically significant by the investigator, within the 6 months prior to the first dose of study drug.
11. History of any infection requiring antimicrobial therapy within 2 weeks prior to the first dose of study drug.
12. A history of recurrent (more than one episode) herpes zoster, disseminated (a single episode) herpes zoster or disseminated (a single episode) herpes simplex.
13. A patient who was vaccinated or exposed to a live or attenuated vaccine within the 6 weeks prior to the first dose of study drug, expects to be vaccinated or exposed to these vaccines during treatment, or during the 6 weeks following discontinuation of study drug. (See Section 4.5.2. for further information regarding avoidance of household contacts who may be vaccinated).
14. A patient with any condition possibly affecting oral drug absorption, eg, gastrectomy, clinically significant diabetic gastroenteropathy, or certain types of bariatric surgery such as gastric bypass. Procedures such as gastric banding, that simply divide the stomach into separate chambers, are NOT exclusionary.
15. History of alcohol or substance abuse, unless in full remission for greater than 6 months prior to first dose of study drug.
16. Screening 12-lead ECG that demonstrates clinically relevant abnormalities which may affect patient safety or interpretation of study results.
