Primary Outcome Measures:
  • American College of Rheumatology (ACR) 20 at Week 12 [ Time Frame: 0 and 12 weeks ]
    ACR 20, the American College of Rheumatology (ACR) definition of 20% improvement is based on a 20% improvement (compared to baseline values) in tender and swollen joint counts and 20% improvement in 3 of the remaining 5 core set measures (subject global assessment of pain, subject global assessment of disease activity, physician global assessment of disease activity, subject assessment of physical function) and one acute phase reactant value (CRP).

Enrollment: 24
Study Start Date: June 2008

Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

all patients get treatment
Drug: rituximab
treatment with rituximab
Other Name: rituxan

Detailed Description:
Using repeated arthroscopic biopsies of patients with rheumatoid arthritis, the researchers will assess changes in the immune response that occur after treatment with rituximab.
