Title: A Randomized, Double-blind Study of Safety and Reduction in Signs and Symptoms During Treatment With Tocilizumab Versus Placebo, in Combination With Methotrexate, in Patients With Moderate to Severe Active Rheumatoid Arthritis and Inadequate Response to Anti-TNF Therapy
Brief Summary: This 3 arm study will compare the safety and efficacy, with regard to reduction of signs and symptoms, of tocilizumab versus placebo in combination with methotrexate (MTX) in patients with moderate to severe active rheumatoid arthritis (RA) currently on MTX therapy, and who have had an inadequate response to prior therapy with an anti-tumor necrosis factor (anti-TNF) agent. Patients will be randomized to receive tocilizumab 4mg/kg iv, tocilizumab 8mg/kg or placebo iv, every 4 weeks. All patients will also receive methotrexate 10-25mg/week. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

Exclusion Criteria:

* contraindication for methotrexate or anti-TNF
B: 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;

C: 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.

* At least 1 erosion in hands/wrists or positive anticyclic citrullinated peptides or rheumatoid factor
* Clinically detectable synovitis of at least 1 wrist/ankle at screening and baseline
* Participants must have been treated with methotrexate, on a weekly dose of at least 15 mg or a maximum tolerated dose (such as, 10 mg weekly) for at least 3 months before screening. Dose of methotrexate must be stable for at least 28 days prior to the first study dose (Day 1)
