ACTEMRA/RoACTEMRA (tocilizumab) has been evaluated in a broad range of patient populations in the most comprehensive clinical development programme supporting a first biologic licence application for an RA treatment – with more than 4,200 patients enrolled.1,2
Study populations enrolled in the clinical programme had a balanced geographical distribution.

The efficacy of ACTEMRA/RoACTEMRA in alleviating the signs and symptoms of RA was assessed in five randomised, double-blind, multicentre Phase III studies.
All studies enrolled patients ≥18 years of age with moderate to severe active RA diagnosed according to the American College of Rheumatology (ACR) criteria and who had at least eight tender and six swollen joints at baseline.
