Primary Outcome Measures:

To compare the efficacy of 2 doses of CP-690,550 versus placebo for the treatment of signs and symptoms of rheumatoid arthritis as measured by ACR 20 response rates. [ Time Frame: 6 month ] [ Designated as safety issue: No ]
To compare evidence of preservation of joint structure following administration of 2 doses CP-690,550 versus placebo as measured by changes from baseline. [ Time Frame: 6 months ] [ Designated as safety issue: No ]
To compare physical function status of patients after administration of 2 doses of CP-690,550 versus placebo using the HAQ-DI. [ Time Frame: 3 months ] [ Designated as safety issue: No ]
To evaluate the safety and tolerability of 2 doses of CP-690,550 versus placebo. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
To compare the rate of achieving DAS28-4 (ESR) <2.6 after administration of CP‑690,550 in doses of 5 mg BID or 10 mg BID versus placebo at Month 6 in patients with active RA on a stable background of methotrexate [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To compare the efficacy of 2 doses of CP-690,550 versus placebo measured by ACR20, ACR 50, ACR70 and DAS 28 response rates. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
To compare the durability of ACR20, ACR50, and ACR70 and DAS 28 response rates. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
To compare the incidence of DAS 28 <2.6 and DAS28 <or =3.2 at each visit. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
To compare effects on all health outcomes measures in the study at each visit, as appropriate for the specific outcome, compared to baseline. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
To investigate possible associations between genomic and metabolomic variation in relation to interventions in an optional supplement requiring separate consent not required for participation in primary study. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
To compare evidence of preservation of joint structure following administration of 2 doses CP-690,550 versus placebo as measured by changes from baseline. [ Time Frame: 12 & 24 months ] [ Designated as safety issue: No ]
To evaluate the safety and tolerability of 2 doses of CP-690,550 versus placebo. [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
