Title: A Randomized, Placebo-controlled, Double-blind, Multicenter Study to Evaluate the Safety and Efficacy of Rituximab in Combination With Methotrexate in Patients With Active Rheumatoid Arthritis Who Have Had an Inadequate Response to Anti-TNF Alpha Therapies
Brief Summary: This study will assess the safety and efficacy of rituximab combined with MTX in participants with active rheumatoid arthritis (RA) who have had an inadequate response to anti-Tumor Necrosis (TNF) alpha therapy. The anticipated time in the study is up to 2 years and the target sample size is 500 participants. Eligible participants may receive re-treatment with rituximab under a separate protocol WA17531.


Options:
A: Inclusion Criteria:

* The patient must meet the American College of Rheumatology (ACR) classification criteria for the diagnosis of rheumatoid arthritis by satisfying at least four of the seven criteria.
* The patient must have active disease at both Screening and predose on Day 1 of Period 1.
* Patient must have had an inadequate response to at least one disease-modifying antirheumatic drug (DMARD), non-biologic or biologic, due to ineffectiveness or intolerance.

Exclusion Criteria:

* Pregnant or lactating women
* Serious medical conditions that would make treatment with CP-690,550 potentially unsafe.
* A patient who has a history of asthma, multiple allergies or severe allergy (eg, anaphylaxis) to any substance. In particular, a history of allergy to iodine, povidone-iodine, iohexol or other iodinated contrast media.
B: Inclusion Criteria:

* Adult participants 18-80 years of age with active RA for at least 6 months;
* Received treatment for RA on an outpatient basis and experienced an inadequate response or intolerance to treatment with at least 1 anti-TNF alpha therapy (etanercept, infliximab or adalimumab);
* Must have received MTX for a minimum of 12 weeks, with the last 4 weeks, prior to screening at a stable dose;
* Participants with swollen joint count (SJC) and tender joint count (TJC) of at least 8 joints at screening and at randomization;
* Radiographic evidence of at least 1 joint with a definite erosion due to RA;
* Participants of reproductive potential must be using reliable contraceptive methods.

Exclusion Criteria:

* Bone or joint surgery within 8 weeks prior to screening or joint surgery planned within 24 weeks of randomization;
* Class IV functional status of RA;
* Previous treatment within 6 months with intravenous gamma globulin, or the Prosorba column;
* Intraarticular or parenteral corticosteroids within 4 weeks prior to screening visit;
* With a live vaccine within 4 weeks prior to randomization;
* Previous treatment with rituximab or other cell-depleting therapies;
* Concurrent treatment with any disease-modifying anti-rheumatic drug (except for MTX) or any anti-TNF alfa factor or other biologic therapy;
* History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies;
* Evidence of significant uncontrolled concomitant diseases such as cardiovascular disease, nervous system, pulmonary, renal, hepatic, endocrine or gastrointestinal disorders;
* Known contraindications to receiving rituximab;
* Known active bacterial, viral, fungal, mycobacterial or other infection;
* History of recurrent significant infection or history of recurrent bacterial infections;
* Primary or secondary immunodeficiency (history of, or currently active);
* History of cancer, including solid tumors and hematologic malignancies (except basal cell or squamous cell carcinoma of the skin that have been excised and cured);
* Women who are pregnant or breast-feeding;
* History of alcohol, drug or chemical abuse within 6 months prior to screening;
* Neuropathies and neurovasculopathies which might interfere with pain evaluation;
* Participants with poor peripheral venous access;
* Intolerance or contraindications to oral or intravenous corticosteroids.
C: Inclusion Criteria:

* adult patients at least 18 years of age with moderate to severe active RA for at least 6 months;
* inadequate response to current anti-rheumatic therapies, including MTX;
* inadequate response or intolerance to treatment with 1 or more anti-TNF therapies within 1 year of entering study;
* on stable MTX for at least 8 weeks before entering study;
* patients of reproductive potential must be using reliable methods of contraception.

Exclusion Criteria:

* major surgery (including joint surgery) within 8 weeks before screening, or planned major surgery within 6 months after entering study;
* women who are pregnant or breast-feeding.
D: Inclusion Criteria

* Subject must be 18 or older and in good health
* Subject must meet the definition of early rheumatoid arthritis (RA) defined by the 1987-revised American College of Rheumatology (ACR) classification criteria and had disease duration of less than 1 year from diagnosis
* Subject must have a Disease Activity Score (DAS28, based on C-reactive protein) greater than 3.2, at least 6 swollen joints out of the 66 assessed, and at least 8 tender joints out of the 68 assessed
* Subject must fulfill at least one of the following three criteria:

  * Rheumatoid factor positive
  * Greater than 1 joint erosion
  * Anti-cyclic citrullinated peptide (CCP) antibody positive.

Exclusion Criteria

* Subject has previously received systemic anti-tumor necrosis factor (TNF) therapy
* Subject has received any biologic or investigational therapy within 6 weeks prior to Baseline
* Subject has been previously treated with more than 2 disease-modifying antirheumatic drugs (DMARDs) or MTX, had been treated with intra-articular or parenteral administration of corticosteroids in preceding 4 weeks, or had undergone joint surgery within the preceding 2 months at joints to be assessed during the study.
