Background

Vedolizumab is an α4β7 integrin monoclonal antibody indicated for moderately to severely active Crohn’s disease (CD) and ulcerative colitis (UC). There are limited data on how vedolizumab impacts extraintestinal manifestations (EIM) in inflammatory bowel disease (IBD).

The aim of the study was to analyse the effect of vedolizumab on EIM in a real-world cohort of IBD patients.

Methods

A multicentre retrospective study was conducted in Belgium, Denmark, Israel, the Netherlands and Switzerland. Adult patients with moderately to severely active IBD and concurrent active EIM with at least 6 months follow-up after vedolizumab initiation (index date) were enrolled. Improvement of EIM was defined as absence of symptoms (resolution) or partial response (reduction of symptoms).

Results

99 patients were included (UC: 44, CD: 55); the majority of active EIM at index were musculoskeletal (Table 1). Median disease duration at index was 9 (IQR: 3-19) years and 77% of patients had been exposed to 1+ biologic.
Overall, after 6 and 12 months of vedolizumab, 37% and 50% of EIM respectively were reported as improved, 22%, 25% as stable (no change) and 1% and 3% as worsened (Table 2), missing values were 5% and 4%, respectively. Median time since first EIM improvement was 0.5 months (Figure 1).
At 6 and 12 months, 48% (10/21) and 33% (6/18) of patients experienced clinical response/remission of their IBD, respectively.
Vedolizumab treatment persistence at 12 months was 83% overall (Figure 2).
Adverse Events were reported for 18% patients; 96% of them non-serious.

Conclusion

Vedolizumab treatment was associated with an improvement in 37% and 50% of EIM at 6 and 12 months, respectively, in a real-world IBD cohort.
