Background: efficacy and safety were evaluated after switching to a biosimilar infliximab (CPT-13) in patients with inflammatory bowel disease (IBD). However, few cohort studies compare the pharmacokinetic profiles, immunogenicity, and safety of the reference infliximab (IFX) and CPT-13 in a real clinical setting.
Objective: to compare the pharmacokinetic profiles and drug survival on the long term of reference IFX and CPT-13 at weeks 54 and 104.
