First received: December 23, 2009
Last updated: May 6, 2013
Last verified: May 2013
This study is designed to compare the effectiveness of the experimental drug, CP-690,550, to methotrexate in preventing joint damage and improving symptoms of rheumatoid arthritis. This study will also compare the safety of CP-690,550 with methotrexate.

Primary Outcome Measures:
  • Comparison of baseline and month 6 scores of PA hand and AP foot radiographs obtained, read and scored by a central facility [ Time Frame: comparison of baseline and month 6 ]
  • ACR 70 responder rate [ Time Frame: month 6 and all other timepoints ]
  • Incidence and severity of adverse events and clinical laboratory abnormalities [ Time Frame: all time points ]
  • Summary of changes in physical examination compared to baseline by patient [ Time Frame: all time points ]
  • Mean change from baseline in vital signs (blood pressure, heart rate, and temperature) measurements; categorical summary of absolute vital signs and vital sign changes compared to baseline by patient [ Time Frame: all time points ]

Secondary Outcome Measures:
  • Change from baseline of scores of PA hand and AP foot radiographs [ Time Frame: month 12, 24 ]
  • Patients who drop out of A3921069 early will have radiographs obtained at last study visit, if previous radiographs were obtained more than 3 months prior to end of study visit. [ Time Frame: all time points ]
  • Period radiographs will be obtained in all patients who discontinue from this study and enroll in open-label, long-term study A3921024. Changes in joint structure seen in A3921024 will be scored using validated method, similar to that used in this study. [ Time Frame: all time points ]
  • ACR 20, 50, and 70 responder rates [ Time Frame: all time points ]
  • DAS 28-3 (CRP) and DAS 28-4 (CRP) [ Time Frame: all time points ]
  • DAS 28-3 (ESR) and DAS 28-4 (ESR) at participating sites (dependent upon availability of a local laboratory that can report ESR results directly to the central laboratory, to ensure blinding of data). [ Time Frame: all time points ]
  • Physical function and patient reported outcomes [ Time Frame: various timepoints ]

Enrollment: 968
Study Start Date: January 2010
