NOR-SWITCH study overview

NOR-SWITCH is the first RCT evaluating the effect of switching from Remicade™† (infliximab) to INFLECTRA®/CT-P13 (infliximab)2

NOR-SWITCH study design

No inferiority§ in disease worsening

  • Stable patients switching to CT-P13 experienced no difference in disease worsening across all indications than those remaining on Remicade™ (infliximab) therapy#2

Disease worsening at Week 52¶2

Per-protocol set population. Primary endpoint. Created from Jørgensen KK, et al. 2017


  • There was a similar adverse event profile in stable patients switching from Remicade™ (infliximab) to CT-P13 compared to those remaining on Remicade™ (infliximab) therapy2


Treatment-emergent adverse events2

Safety population. Created from Jørgensen KK, et al. 2017.



*CT-P13 was designed with comparable efficacy, safety and quality to reference infliximab, to increase the treatment options for your Crohn’s disease and ulcerative colitis patients.5,6 Increasing real-world experience confirms the CT-P13 clinical efficacy and safety profile.7

†Remicade is a registered trademark of MSD.

‡CT-P13 is marketed under different brand names including INFLECTRA® and REMSIMA™.

§According to a prespecified margin of 15%. The study was not powered to show non-inferiority in individual diseases.

#Only single one-way switching from Remicade™ to CT-P13 was examined in this study.
 ¶The NOR-SWITCH trial included only patients on Remicade™ and CT-P13; its findings do not support that any other biosimilars of infliximab can achieve the same result.
