Background: Vedolizumab, an anti-integrin antibody, has proven to be effective in adults with inflammatory bowel disease [IBD], but the data in paediatrics are limited. We describe the short-term effectiveness and safety of vedolizumab in a European multi-centre paediatric IBD cohort. Method: Retrospective review of children [aged 2-18 years] treated with vedolizumab from 19 centres affiliated with the Paediatric IBD Porto group of ESPGHAN. Primary outcome was Week 14 corticosteroid-free remission [CFR]. Results: In all, 64 children were included (32 [50%] male, mean age 14.5 ± 2.8 years, with a median follow-up 24 weeks [interquartile range 14-38; range 6-116]); 41 [64%] cases of ulcerative colitis/inflammatory bowel disease unclassified [UC/IBD-U] and 23 [36%] Crohn's disease [CD]. All were previously treated with anti-tumour necrosis factor [TNF] [28% primary failure, 53% secondary failure]. Week 14 CFR was 37% in UC, and 14% in CD [P = 0.06]. CFR by last follow-up was 39% in UC and 24% in CD [p = 0.24]. Ten [17%] children required surgery, six of whom had colectomy for UC. Concomitant immunomodulatory drugs did not affect remission rate [42% vs 35%; p = 0.35 at Week 22]. There were three minor drug-related adverse events. Only 3 of 16 children who underwent endoscopic evaluation had mucosal healing after treatment (19%). Conclusions: Vedolizumab was safe and effective in this cohort of paediatric refractory IBD. These data support previous findings of slow induction rate of vedolizumab in CD and a trend to be less effective compared with patients with UC.
