Title: Phase 3 Randomized, Double Blind, Placebo Controlled Study Of The Efficacy And Safety Of 2 Doses Of CP-690,550 In Patients With Active Rheumatoid Arthritis On Background Methotrexate
Brief Summary: This study is designed to provide safety and efficacy data to support the development of CP-690,550 in patients with moderate to severe rheumatoid arthritis on background of methotrexate.


Options:
A: Inclusion Criteria:

* Adult patients, ≥ 18 years of age.
* Rheumatoid arthritis of \> 6 months duration.
* Intolerant of methotrexate or continued treatment with methotrexate is considered inappropriate.
* All disease-modifying anti-rheumatic drugs (DMARD) are to be withdrawn prior to receiving study drug.
* Weight ≤ 150 kg.

Exclusion Criteria:

* Major surgery (including joint surgery) within 12 weeks prior to baseline or planned major surgery within 6 months after baseline.
* History of or current inflammatory joint disease other than rheumatoid arthritis (RA).
* Treatment with a biologic agent at any time prior to baseline.
* Intra-articular or parenteral corticosteroids ≤ 4 weeks prior to baseline.
* Active current infection or history of recurrent bacterial, viral, fungal or mycobacterial infection.
B: Inclusion Criteria:

* Diagnosis of rheumatoid arthritis.
* Currently receiving an optimal dose of oral Methotrexate (MTX)(at least 15 mg/week but no more than 25 mg/week) for the treatment of rheumatoid arthritis.
* Active rheumatoid arthritis at the time of screening.

Exclusion Criteria:

* Previous or current treatment with etanercept, other tumor necrosis factor-alpha (TNF) inhibitors, or other biologic agents.
* Concurrent treatment with any disease-modifying anti-rheumatoid drugs (DMARD), other than MTX within 28 days before baseline.
* Concurrent treatment with more than 1 non-steroid anti-inflammatory drug (NSAID) at baseline.
C: Inclusion Criteria:

* Adults with moderate to severe rheumatoid arthritis on a stable dose of methotrexate

Exclusion Criteria:

* Pregnancy, severe acute or chronic medical conditions, including serious infections or clinically significant laboratory abnormalities.
D: Inclusion Criteria:

* All patients must fulfill ACR classification criteria for rheumatoid arthritis.
* All patients must have been 16 years of age or older at time of diagnosis of rheumatoid arthritis.
* All patients must be 18 years of age or older at the time of entry into the study.
* All patients will have been receiving oral or subcutaneous methotrexate 15 to 25 mg/week (unless intolerant and on a minimum 10 mg/week) at a constant dose for at least 4 weeks, and on any methotrexate for no less than 12 weeks.
* All patients will have active disease as defined by a DAS28 of greater than or equal to 4.4.
* If patients are receiving corticosteroids, they must have been on stable dose (less than or equal to 10 mg prednisone or equivalent) for at least two weeks prior to screening.
* If patients are using non-steroidal anti-inflammatory drugs (NSAIDs), they must be on stable doses for at least one week prior to screening.
* If patients have taken leflunomide, cyclosporine, gold, Anakinra, azathioprine, or penicillamine in combination with methotrexate, they must have stopped this therapy at least 8 weeks prior to randomization.
* Laboratory tests must meet the following criteria within 2 weeks of randomization:

  * Serum creatinine 1.8 mg/dL

  * WBC 3000 mc/L
  * Neutrophils 1000 mc/L
  * Platelets 100,000 mc/L
  * Serum transaminase level (AST or ALT, whichever is followed at the site) not exceeding 1.2 times upper limit of normal.
  * Albumin no less than 1.0 g/dL (10 g/L) below lower limit of normal. Anything below lower limit of normal must have been stable (or improving) for no less than 90 days. Stable is defined as changes of no more than 0.2 g/dL (2 g/L).
* All patients must be capable of giving informed consent and able to adhere to study visit schedule.
* Subject or designee must have the ability to self-inject investigational product or have a caregiver who can inject subcutaneous injections
* Subjects must meet one of the following criteria with regard to tuberculosis. PPD must be within 180 days of randomization if the patient has no recent exposure/travel history, or within 90 days if the patient has a recent exposure/travel history.

  * Negative PPD; or
  * Positive PPD \<5 mm, with a negative chest x-ray; or
  * Positive PPD \>5mm, treated for at least 28 days with INH.
* Subjects with an Erythrocyte sedimentation rate (ESR) of less than or equal to 10 and a tender and swollen joint count of at least 10 and does not qualify for the study using the DAS28, will be allowed to use the DAS28-CRP rather than the traditional DAS28 to determine eligibility.

Exclusion Criteria:

* Previous intolerance to methotrexate (unless able to tolerate at least 10 mg/week)
* Sensitivity to study medications
* Previous treatment with methotrexate, sulfasalazine or hydroxychloroquine in combination with each other for longer than 4 weeks duration. No combination use is allowed within 4 weeks of screening.
* No bed or wheelchair-bound patients
* Previous treatment with a TNF- inhibitor (etanercept, infliximab or adalimumab) for more than 5 weeks of therapy. Previous treatment with TNF- inhibitor must have been stopped for reasons other than toxicity or efficacy. No TNF- inhibitor therapy is allowed within the following time frames:

  * Last dose of etanercept must have been at least 4 weeks before screening.
  * Last dose of adalimumab or infliximab must have been at least 8 weeks prior to screening.

Example of an eligible patient: A patient found he could not afford the co-pays for a TNF inhibitor after two doses and stopped taking the medication two months before being evaluated for this trial.
