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. Overall, five randomized controlled studies have been performed. For the other extrapolated indications, many observational induction and switching studies also support the utility of CT-P13 in the treatment of inflammatory diseases. Here, we review profiles of CT-P13 including physicochemical properties, clinical efficacy and safety data in all indications and current status.
