Primary Outcome Measures:
  • Comparison of each subject's synovial tissue markers [ Time Frame: at baseline and after 4 months of treatment with abatacept ]

Secondary Outcome Measures:
  • assess baseline & post treatment synovitis by dynamic gadolinium enhanced MRI; determine concentrations of abatacept in synovial fluid & serum [ Time Frame: after 4 months of treatment ]
  • assess safety & tolerability of abatacept [ Time Frame: administered for 4 months ]
