Rheumatoid arthritis (RA) is a chronic inflammatory disease (a long-lasting disease causing pain and swelling) associated with significant health problems. It is a difficult disease to manage as the disease is often unpredictable. RA causes inflammation (swelling) of the joints that can cause joint damage, deformity, and progressive disability and impairment. It is estimated that 1% of the world's population suffers from this disease.

The purpose of this research study is to determine if a change in inflammation seen on the ultrasound is a good indicator of how subjects' rheumatoid arthritis is responding to treatment of subcutaneous abatacept at 3 weeks, 3 months, 6 months, and 12 months.

Further study details as provided by Dr. Veena Ranganath, University of California, Los Angeles:

Primary Outcome Measures:
  • 12 Month Change in 7-Joint Ultrasound (US) Inflammatory Score [ Time Frame: baseline, 12 months ]
    The 7-joint US inflammatory score includes the addition of synovial hypertrophy scores and power doppler scores.

Secondary Outcome Measures:
  • 12 Month Change in Power Doppler Ultrasound (PDUS) Scores [ Time Frame: baseline, 12 months ]
    There were seven different joints in the hands and wrists evaluated to score the PDUS.

  • 12 Month Change in Gray-scale Ultrasound (GSUS) [ Time Frame: baseline, 12 months ]
    There were seven different joints in the hands and wrists evaluated to score the GSUS.
