This 3 arm study will assess the efficacy of MabThera in the prevention of progr ession of structural joint damage in patients with active rheumatoid arthritis w ho have an inadequate clinical response to methotrexate. Patients will be random ized to receive MabThera 1000mg i.v., MabThera 500mg i.v. or placebo i.v. on day s 1 and 15; all patients will receive concomitant methotrexate at a stable dosag e of 12.5-25mg/week throughout the study. Further courses of MabThera will be pr ovided to eligible patients. Structural joint damage will be assessed by magneti c resonance imaging (MRI) at baseline, and at intervals during the study. The an ticipated time on study treatment is 1-2 years, and the target sample size is 10 0-500 individuals.
