BACKGROUND: Infliximab biosimilars are the first biosimilars of monoclonal antibodies approved by the main regulatory agencies. Up to the present day, two infliximab biosimilars have been approved: CT-P13 (Celltrion), and SB2 (Biogen), but other companies have been developing candidate infliximab biosimilars that are on clinical trials: PF 06438179 (Pfizer), the ABP710 (bioCentury/Amgen) the BCD055 (JSC Biocad Russica) and BOW015 (Epirus). METHODS: We have made a literature search in MedLine database using the key words [Infliximab] and [biosimilars] and [rheumatic diseases] and [rheumatisms]...

BACKGROUND: Biologic drugs have revolutionised the management of many inflammatory conditions. Patent expirations have stimulated development of highly similar but non-identical molecules, the biosimilars. Extrapolation of indications is a key concept in the development of biosimilars. However, this has been met with concerns around mechanisms of action, equivalence in efficacy and immunogenicity, which are reviewed in this article. METHODS: Narrative overview composed from literature search and the authors' experience...

The first biosimilar infliximab, CT-P13 (infliximab-dyyb) has been used for the treatment of inflammatory diseases for 4 years. CT-P13 has highly similar efficacy and safety profiles with a lower price than the originator infliximab and has been approved in 81 countries. Despite approval for clinical use, some knowledge gaps still limit the widespread and pertinent use of biosimilar CT-P13. One of the most important factors for proper utilization of CT-P13 for the treatment of immune-mediated inflammatory diseases is confidence in CT-P13, which could be enhanced by scientific evidence supporting the biosimilarity of CT-P13...

The introduction of biological agents has led to significant changes in the treatment of inflammatory bowel disease (IBD). The relatively high price of infliximab (IFX) and the expiration of the patents led to the introduction of biosimilar agents. CT-P13 was the first IFX biosimilar approved in the same indications as the reference product; however, the approval was based on randomized clinical trials conducted in patients with rheumatoid arthritis and ankylosing spondylitis. In the past 2-3 years, new findings from prospective observational studies supported the short-, medium- and long-term clinical efficacy and safety of CT-P13 in patients with IBD...

Antibodies directed to tumour necrosis factor-α (TNF-α) are very effective in treating paediatric Crohn's disease (CD). Over the last few years, research has provided important new insights into how to optimise this treatment's effectiveness. Research on predictors for anti-TNF treatment responsiveness has revealed potential markers, but data on their accuracy in paediatric CD patients are lagging behind. Also, new evidence has become available on the safety profile of anti-TNF antibodies that suggests the assumed increased malignancy risk seen in patients on anti-TNF and thiopurine combination treatment may be linked more to thiopurine use and not to anti-TNF treatment...

Determining biosimilarity involves a comprehensive exercise with a focus on determining the comparability of the molecular characteristics and preclinical profile of the biosimilar and reference product, such that there is less need for extensive clinical testing to assure comparability of clinical outcomes. Three anti-TNF biosimilar agents are approved for patients with rheumatic diseases in the European Union. The infliximab (Remicade®) biosimilars CT-P13 (Remsima® and Inflectra®) and SB2 (Flixabi®) and the etanercept (Enbrel®) biosimilar SB4 (Benepali®) have shown close comparability to their reference medicinal products, having undergone extensive evaluations...

BACKGROUND: Biological agents, such as infliximab, have transformed the outcomes of patients with immune-mediated inflammatory diseases. The advent of biosimilar treatment options such as CT-P13 promises to improve the availability of biological therapy, yet real-world switching data are currently limited. Here, we assess the effectiveness and safety of switching to CT-P13 from infliximab reference product (RP) in patients with inflammatory bowel disease. MATERIALS AND METHODS: This was a prospective single-center observational study in patients with moderate to severe Crohn's disease (CD) and ulcerative colitis (UC)...

The introduction of biological agents drastically changed the treatment paradigm of inflammatory arthritides, ameliorating the natural history of the diseases but concomitantly increasing the drug costs due to the manufacturing process. On this concern, biosimilar drugs may represent a valid option for reducing this elevated cost and increasing the availability of these highly effective treatments. Recently, CT-P13, the first biosimilar of infliximab, has been approved with the same indications established for the reference product (RP), and its daily use is progressively increasing...

PURPOSE OF REVIEW: After expiry of the patent of originator anti-tumor necrosis factor drug infliximab (Remicade), CT-P13 was in 2013 the first infliximab biosimilar to be approved by the European Medicine Agency (EMA) for the same indications as the reference drug, including paediatric inflammatory bowel disease (IBD). The approval was based on extrapolation, after extensive in-vitro studies and clinical experience in patients with ankylosing spondylitis and rheumatoid arthritis. The extrapolation of CT-P13 to IBD and to paediatric patients raised concerns among paediatric IBD specialists...
