ORBIT: information for clinicians


The primary purpose of the trial is to identify whether rituximab therapy or anti-TNF therapy is more effective in improving the clinical symptoms, signs, physical function and health-related quality of life of patients with active rheumatoid arthritis.

The secondary purposes are to:

  • assess the relative cost-effectiveness of these treatments
  • prospectively evaluate the influence of mood on response to, and side-effect profile from, anti-TNF and rituximab
  • identify whether synovial immuno-histology at baseline predicts differential response to rituximab and anti-TNF therapy.
