    Abstract:
    CT-P13 (Remsima™; Inflectra™), a biosimilar of reference infliximab (Remicade(®)), is approved by the European Medicines Agency for use in all indications for which reference infliximab is approved, including rheumatoid arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, psoriatic arthritis and psoriasis. Infliximab is a chimeric human-murine monoclonal antibody against the proinflammatory cytokine tumour necrosis factor-α. The CT-P13 infliximab formulation is identical to that of reference infliximab and it has similar physiochemical characteristics. The approval of CT-P13 was based on the results of a rigorous, comparability exercise. This article reviews the results of that exercise, focusing on the clinical evaluation programme. In two well-designed clinical trials, CT-P13 was equivalent to reference infliximab in terms of pharmacokinetic properties in patients with ankylosing spondylitis and in terms of efficacy in patients with rheumatoid arthritis. In both studies, CT-P13 was generally well tolerated with a similar tolerability profile to that of reference infliximab. Immunogenicity evaluations demonstrated that the proportion of patients developing anti-drug antibodies was similar with each agent. Preliminary data from trial extensions demonstrated that in patients who switched from reference infliximab to CT-P13, efficacy was sustained and similar to those who were treated continuously with CT-P13. As with all biosimilar and generic agents, CT-P13 has the potential to reduce treatment costs compared with those of reference infliximab, and modelled analyses predict significant cost savings compared with reference infliximab. In conclusion, CT-P13 is an infliximab biosimilar that provides a useful alternative to reference infliximab in patients requiring infliximab therapy.
