Low-dose rituximab protocol in rheumatoid arthritis-outcome and economic impact.

Objectives: A significant proportion of RA patients, particularly those associated with poor prognostic factors, fail on conventional DMARDs (cDMARDs).

Numerous, albeit small, studies using lower doses have shown contradictory results.
