This randomized, double-blind, placebo controlled, parallel group study will assess the efficacy and safety of rituximab [MabThera/Rituxan] in patients with severe active rheumatoid arthritis refractory to at least one anti-TNF treatment, using magnetic resonance imaging (MRI) of the hand for efficacy measurement. Patients will be randomized to receive 2 intravenous infusions 14 days apart of either 1000mg MabThera (group A) or placebo (group B). All patients will receive methotrexate 10-25mg weekly. Patients in group A demonstrating clinical response at week 24 may receive further cycles of MabThera, patients in group B without clinical response will also be treated with active MabThera. Anticipated time on study treatment is up to 2 years. Target sample size is <50 patients.

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
An antineoplastic antimetabolite with immunosuppressant properties. It is an inhibitor of TETRAHYDROFOLATE DEHYDROGENASE and prevents the formation of tetrahydrofolate, necessary for synthesis of thymidylate, an essential component of DNA.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
An enzyme of the oxidoreductase class that catalyzes the reaction 7,8-dihyrofolate and NADPH to yield 5,6,7,8-tetrahydrofolate and NADPH+, producing reduced folate for amino acid metabolism, purine ring synthesis, and the formation of deoxythymidine monophosphate. Methotrexate and other folic acid antagonists used as chemotherapeutic drugs act by inhibiting this enzyme. (Dorland, 27th ed) EC 18.104.22.168.
