Comparing Long-Term Infliximab Persistence Following a Switch to a Biosimilar in Patients With Inflammatory Bowel Disease: No Cause for Concern.

Introduction: Several studies have demonstrated that switching stable patients with inflammatory bowel disease (IBD) from originator to biosimilar infliximab is noninferior to continuing originator infliximab. However, "real-world" data comparing long-term outcomes between switch and nonswitch cohorts is lacking. This study aimed to address this gap by comparing long-term outcomes in IBD patients across switch and nonswitch cohorts.
