Data regarding double switching from originator infliximab (IFX) to IFX biosimilars in inflammatory bowel diseases (IBDs) are lacking. The purpose of this study was to evaluate the safety and efficacy of switching from originator IFX to CT-P13 and subsequently to SB2 (double switch) in patients with IBD. Patients undergoing IFX-double switch in eight Centers in Lombardy (Italy) from November 2018 to May 2019 were retrospectively analyzed. The IFX discontinuation rate, incidence and type of adverse events (AEs), and clinical remission rate were recorded. A comparison with a control group of patients with IBD single-switched from originator IFX to CT-P13 was performed, before and after an inverse probability of treatment weighting (IPTW)-based propensity score analysis. Fifty-two double-switched patients with IBD were enrolled. The 24- and 52-week proportions of patients continuing on IFX therapy following the second switch (CTP13→SB2) were 98% (95% confidence interval [CI] 94%–100%) and 90% (95% CI 81%–99%), respectively. Four patients experienced a total of five AEs, all graded 1–3 according to Common Terminology Criteria for Adverse Events (CTCAE). No infusion reactions were observed. The 24-week and follow-up end clinical remission rates following the second switch were 94% and 88%, respectively. No differences were observed in the safety and efficacy outcomes by comparing the double-switch group with a single-switch group of 66 patients with IBD; all these results were confirmed by IPTW-adjusted analysis. The study suggests both the safety and efficacy of the double switch from originator IFX to CT-P13 and SB2 in patients with IBD is maintained. This strategy may be associated with potential cost implications.
