Erratum to: Interleukin-6: a new therapeutic target

Following the publication of the above article [1], we noticed that due to an administrative oversight the Competing interests section was incomplete and should read as follows:

JSS has received financial compensation from and served on advisory boards for Roche and is an investigator in clinical trials of tocilizumab. RNM has received consulting fees from Chugai; served on an ad hoc advisory board for Roche; and was responsible for the planning and preparation for publication of the Phase II European (CHARISMA) trial of tocilizumab with and without methotrexate. A patent for co-administration of methotrexate and tocilizumab for the treatment of rheumatoid arthritis, of which RNM is named as a co-inventor, has been applied for and fully assigned to Chugai.
