1. Evidence of a signed and dated informed consent document indicating that the patient has been informed of all pertinent aspects of the study.
2. Patients 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. The patient has a diagnosis of RA based upon the American College of Rheumatology (ACR) 1987 Revised Criteria.
5. The patient has active disease at both Screening and Baseline, as defined by both: a. =6 joints tender or painful on motion; AND b. =6 joints swollen and fulfills 1 of the following 2 criteria at Screening: 1. ESR (Westergren method) >28 mm in the local laboratory. 2. CRP >7 mg/L in the central laboratory.
6. The patient meets ACR 1991 Revised Criteria for Global Functional Status in RA,10 Class I, II or III.
7. No evidence of active or latent or inadequately treated infection with Mycobacterium tuberculosis (TB) as defined by all of the following:
• A negative QuantiFERON Gold®™ test or, if unavailable, a negative Mantoux PPD skin test using 5 TU PPD (<5 mm of induration performed within the 3 months prior to screening).
• A chest radiograph(CXR) within the 3 months prior to screening without changes suggestive of active TB infection.
• No hx of either untreated or inadequately treated latent or active TB infection.
• If a patient has previously received acceptable treatment for either latent or active TB infection, only a CXR need be obtained, if not done within the prior 3 months. A patient who is currently being treated for either latent or active TB infection can only be enrolled with prior approval by the Sponsor.
8. Patient had an inadequate response to at least one DMARD (traditional or biologic) due to lack of efficacy or toxicity.
9. For traditional DMARDS, the following minimum washout criteria apply:
• Methotrexate, 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 following elimination procedure at least 4 weeks prior to the first dose of study drug: Cholestyramine at a dosage of 8 grams three times daily for at least 24 hours, or activated charcoal at a dosage of 50 grams 4 times a day for at least 24 hours.
• 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 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.
10. Biologic Response Modifiers. All must be discontinued for entry into this study:
• Anakinra (Kineret®), Enbrel (Etanercept®): Discontinued 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 8 weeks prior to the first dose of study drug;
• Certolizumab pegol (CimziaTM), Golimumab (SimponiTM) must be
discontinued for 10 weeks prior to the first dose of study drug;
• Abatacept (Orencia®), Tocilizumab (Actemra®)

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 to the power of 9/L;
• Absolute neutrophil count <1.2 x 10 to the power of 9/L;
• Platelet count <100 x 10 to the power of 9/L.
4. Estimated GFR =40 ml/min based on Cockcroft Gault calculation.
5. Total bilirubin, 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.
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.
