RT Journal Article SR Electronic T1 Consensus statement on blocking the effects of interleukin-6 and in particular by interleukin-6 receptor inhibition in rheumatoid arthritis and other inflammatory conditions JF Annals of the Rheumatic Diseases JO Ann Rheum Dis FD BMJ Publishing Group Ltd and European League Against Rheumatism SP 482 OP 492 DO 10.1136/annrheumdis-2012-202469 VO 72 IS 4 A1 Josef S Smolen A1 Monika M Schoels A1 Norihiro Nishimoto A1 Ferdinand C Breedveld A1 Gerd R Burmester A1 Maxime Dougados A1 Paul Emery A1 Gianfranco Ferraccioli A1 Cem Gabay A1 Allan Gibofsky A1 Juan Jesus Gomez-Reino A1 Graeme Jones A1 Tore K Kvien A1 Miho Murakami A1 Neil Betteridge A1 Clifton O Bingham III A1 Vivian Bykerk A1 Ernest H Choy A1 Bernard Combe A1 Maurizio Cutolo A1 Winfried Graninger A1 Angel Lanas A1 Emilio Martin-Mola A1 Carlomaurizio Montecucco A1 Mikkel Ostergaard A1 Karel Pavelka A1 Andrea Rubbert-Roth A1 Naveed Sattar A1 Marieke Scholte-Voshaar A1 Yoshiya Tanaka A1 Michael Trauner A1 Gabriele Valentini A1 Kevin L Winthrop A1 Maarten de Wit A1 Désirée van der Heijde YR 2013 UL http://ard.bmj.com/content/72/4/482.abstract AB Background Since approval of tocilizumab (TCZ) for treatment of rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA), interleukin 6 (IL-6) pathway inhibition was evaluated in trials of TCZ and other agents targeting the IL-6 receptor and ligand in various RA populations and other inflammatory diseases. This consensus document informs on interference with the IL-6 pathway based on evidence and expert opinion. Methods Preparation of this document involved international experts in RA treatment and RA patients. A systematic literature search was performed that focused on TCZ and other IL6-pathway inhibitors in RA and other diseases. Subsequently, incorporating available published evidence and expert opinion, the steering committee and a broader expert committee (both including RA patients) formulated the current consensus statement. Results The consensus statement covers use of TCZ as combination- or monotherapy in various RA populations and includes clinical, functional and structural aspects. The statement also addresses the second approved indication in Europe JIA and non-approved indications. Also early phase trials involving additional agents that target the IL-6 receptor or IL-6 were evaluated. Safety concerns, including haematological, hepatic and metabolic issues as well as infections, are addressed likewise. Conclusions The consensus statement identifies points to consider when using TCZ, regarding indications, contraindications, screening, dose, comedication, response evaluation and safety. The document is aimed at supporting clinicians and informing patients, administrators and payers on opportunities and limitations of IL-6 pathway inhibition.
