Primary Outcome(s)

Main Objective: There are four primary objectives, to be assessed in the following sequence:
1. To compare the efficacy of CP-690,550 in doses of 5 mg BID and 10 mg BID versus
placebo for the treatment of signs and symptoms of rheumatoid arthritis (RA) in
patients with active RA on a stable background of methotrexate, as measured by
ACR20 response rates at Month 6.
2. To compare physical function status of patients after administration of 5 mg BID and 10 mg BID of CP-690,550 versus placebo using the HAQ-DI at Month 3 compared to baseline in patients with active RA on a stable background of methotrexate.
3. To compare the rate of achieving DAS28-4(ESR)<2.6 at Month 6 after administration of 5 mg BID and 10 mg BID of CP-690-550 versus placebo in patients with active RA on stable background methotrexate.
4. To evaluate the safety and tolerability over 12 months of CP-690,550 in doses of
5 mg BID and 10 mg BID versus placebo in patients with active RA on a stable
background of methotrexate.

Primary end point(s): Multiple endpoints will be evaluated during the study to meet the stated objectives.
Signs & Symptoms
• ACR20 responder rates analyzed at all timepoints;
• ACR50 and ACR70 responder rates at all timepoints;
• DAS 28-3 and DAS 28-4 (CRP) at all timepoints;
• DAS 28-3 and DAS 28-4 (ESR) at all timepoints at participating sites (dependent upon availability of a local laboratory that can report directly to the central laboratory, to ensure blinding of data).

Other endpoints for Physical Function, Patient Reported Outcomes and Safety are described in the protocol.

Secondary Objective: 1. To compare the efficacy of oral CP-690,550 in doses of 5mg BID & 10mg BID plus MTX versus placebo plus MTX for the treatment of signs & symptoms of rheumatoid arthritis
2. To compare the efficacy of adalimumab (Humira®) 40mg SC q2 weeks plus MTX versus placebo plus MTX for the treatment of signs & symptoms of rheumatoid arthritis
3. To compare the durability of ACR20, ACR50, & ACR70 & DAS 28 response rates at all visits.
4. To compare the incidence of DAS 28 remission & low disease activity state at all visits.
5. To compare effects on all health outcomes measures compared to baseline in the study at all visits, as appropriate for the specific outcome.
6. To estimate the efficacy of adalimumab (Humira®) 40mg SC q2 weeks versus CP 690,550 in doses of 5 & 10mg BID for the treatment of signs & symptoms in patients with active RA on a stable background of methotrexate
