Background:
CT-P13 is a biosimilar of Remicade®, an agent approved in some countries for use in inflammatory bowel disease (IBD). Controlled clinical trials have demonstrated the efficacy and safety of CT-P13 in rheumatic diseases, but not in IBD.
Aims:
To assess the effectiveness and safety of CT-P13 in IBD patients in real clinical practice.
Methods:
This is a prospective observational study in patients with moderate to severe Crohn's disease or ulcerative colitis treated with CT-P13. The study was performed in one single center. Patients included were naive or switched to anti-TNF treatment from the reference infliximab (Remicade®) to CT-P13. Efficacy and safety were assessed in naive and switched patients who were in remission at the time of the switch at months 3 and 6 of therapy.
Results:
87.5 and 83.9% of switched CD patients who were in remission at the time of the switch continued in remission, and 66.7 and 50% of naive CD patients reached remission, at months 3 and 6. In UC switched cases, 92 and 91.3% of patients in remission at the time of the switch continued in remission, at 3 and 6 months. In naive UC patients, the remission rates were 44.4 and 66.7%, at months 3 and 6. Adverse events occurred in 7.5% of patients during 6 months of study.
Conclusions:
CT-P13 was efficacious and well tolerated in patients with CD or UC.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
