Abstract Background Vedolizumab (VDZ), a gut-selective anti-lymphocyte trafficking integrin antibody, is effective in treating patients with moderately to severely active Crohn’s disease (CD). In this study, we examined the real-world effectiveness and safety of induction therapy using VDZ alone or in combination with budesonide (VDZ + BUD) among patients with CD in Belgium, Israel, and Switzerland. Methods This retrospective chart review analysis included adult patients with moderately to severely active CD who started induction treatment with VDZ or VDZ + BUD (January 2015 through January 2019). The primary objective of this study was to assess the effectiveness in terms of clinical remission of VDZ alone or VDZ + BUD using patient-reported outcomes (PRO) of abdominal pain (AP) and/or loose stool frequency (LSF) (PRO-2) at weeks 0, 2, 6, 10, and 14. Regression models were used to assess differences and associations between the treatment groups. Results Overall, 123 patients were included (VDZ, n = 73; VDZ + BUD, n = 50). Clinical remission rates at week 14 were 71.4% (50/70) and 68.0% (34/50) with VDZ and VDZ + BUD, respectively. Mean percentage change in AP and LSF from baseline to week 14 was comparable between the groups. Median (95% confidence interval [CI]) time to clinical remission was 91 [70.0–98.0] and 95 [70.0–98.0] days, respectively. One patient in each group discontinued VDZ and 68.0% of patients in the VDZ + BUD group discontinued BUD before week 14. The rates of overall adverse events were similar between the groups (VDZ, 23.3%; VDZ + BUD, 26.0%). Conclusions In this retrospective study, VDZ alone and VDZ + BUD showed similar high remission rates in patients with moderately to severely active CD. Prospective randomized studies are needed to conclude on the role of combining VDZ with BUD. Trial registration Not applicable.
