Title: A Phase 1, Randomized, Placebo-Controlled, Two-Period, Fixed Sequence Study To Evaluate The Effect Of CP-690,550 On Measured Glomerular Filtration Rate In Patients With Active Rheumatoid Arthritis
Brief Summary: The purpose of study is to explore the effect of CP-690,550 (Tofacitinib) on measures of kidney function in patients with active rheumatoid arthritis (RA).


Options:
A: Inclusion Criteria:

* Patients with established adult rheumatoid arthritis currently on Methotrexate for at least 3 months

Exclusion Criteria:

* All concomitant diseases or pathological conditions that could interfere and impact the assessment of the study treatment

B: Inclusion Criteria:

* Subject was age 18 or older and in good health (Investigator discretion) with a recent stable medical history.
* Diagnosis of rheumatoid arthritis (RA) as defined by the 1987-revised American College of Rheumatology (ACR) criteria, with a disease duration less than 3 years, at least 8 swollen joints out of the 66 joints assessed, at least 10 tender joints out of the 68 joints assessed, at least 1 joint erosion or rheumatoid factor (RF) positivity, erythrocyte sedimentation rate (ESR) \>= 28 mm/1h or C-reactive protein (CRP) \>= 1.5 mg/dl

Exclusion Criteria:

* Chronic arthritis diagnosed before the age of 16
* Preceding treatment with MTX, cyclophosphamide, cyclosporin, azathioprine or more than 2 other disease-modifying anti-rheumatic drugs (DMARDs)
* Subject previously received anti-tumor necrosis factor (TNF) therapy
* Permanently wheelchair-bound or bedridden patients
* Subject considered by the investigator, for any reason, to be an unsuitable candidate for the study
* Female subject who is pregnant or breast-feeding or considering becoming pregnant
C: Inclusion Criteria:

* Adult patients, ≥18 years of age
* Active rheumatoid arthritis of \>6 months duration
* Received permitted DMARDs each at a stable dose for at least 7 weeks prior to baseline

Exclusion Criteria:

* Rheumatic autoimmune disease or inflammatory joint disease other than rheumatoid arthritis
* Major surgery within 8 weeks prior to screening or planned within 6 months following randomization
* Unsuccessful treatment with a biologic agent, including an anti-TNF agent
* Previous treatment with tocilizumab
D: 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.
