Therapeutic benefit of blocking interleukin‐6 activity with an anti–interleukin‐6 receptor monoclonal antibody in rheumatoid arthritis: A randomized, double‐blind, placebo‐controlled, dose‐escalation trial

This is the first randomized controlled trial showing that inhibition of IL-6 significantly improved the signs and symptoms of RA and normalized the acute-phase reactants. Further research with multiple dosing is necessary to define the most appropriate therapeutic regimen of MRA in RA.
