Switching from reference infliximab to CT-P13 in patients with inflammatory bowel disease: results of a multicenter study after 12 months
Background and aims: infliximab has changed the natural history of inflammatory bowel disease (IBD). The advent of biosimilar treatments such as CT-P13 will hopefully improve the availability of biological therapies. Data with regard to drug switching are currently limited.

| Sumario: | Background and aims: infliximab has changed the natural history of inflammatory bowel disease (IBD). The advent of biosimilar treatments such as CT-P13 will hopefully improve the availability of biological therapies. Data with regard to drug switching are currently limited. The objective of the study was to assess the effectiveness and safety of switch ing from the reference product (RP), infliximab, to CT-P13 in patients with IBD. Methods: this was a multicenter prospective observational study in patients with Crohn’s disease (CD) and ulcerative colitis (UC). All patients had switched from infliximab RP (Remicade®) to CT-P13 treatment and were followed up for 12 months. The efficacy endpoint was the change in clinical remission assessed at 0 and 12 months, according to the Harvey-Bradshaw score and partial Mayo score for patients with CD and UC, respectively. Adverse events were moni tored and recorded throughout the study. Results: a total of 167 patients (116 CD/51 UC) were includ ed; 88.8% (103/116) of patients with CD were in remission at the time of the drug switch and 69.7% were in remis sion at 12 months. The Harvey-Bradshaw (HB) score sig nificantly changed at 12 months (p = 0.001); 84.3% (43/51) of patients with UC were in remission at the time of the drug switch and 76.7% were in remission at 12 months. No significant changes in the median partial Mayo score (p = 0.87) were observed at 12 months. Serious adverse events related to medication were reported in 12/167 (7.2%) cases. Conclusion: switching from infliximab RP to CT-P13 is safe and effective at 12 months. The loss of efficacy at 12 months was 15.7%. |
