💊 Profile

Antagonists to the interleukin-6 receptor block the actions of interleukin-6 and are under investigation for rheumatoid arthritis, systemic-onset juvenile idiopathic arthritis, adult-onset Still’s disease, Crohn’s disease, and haemolytic anaemia. Tocilizumab is a recombinant monoclonal antibody that targets the interleukin-6 receptor and is used for the treatment of Castleman’s disease, a rare lymphoproliferative disorder. It is also used for the treatment of rheumatoid arthritis and juvenile idiopathic arthritis.
