Background: Vedolizumab, an anti-integrin antibody, has proven to be effective in adults with Inflammatory Bowel Disease (IBD), but the data in pediatrics are limited. We describe the short-term effectiveness and safety of vedolizumab in a European multi-center pediatric IBD cohort.
Method: Retrospective review of children (2-18 years) treated with vedolizumab from 19 centers affiliated with the Paediatric IBD Porto group of ESPGHAN. Primary outcome was week 14 corticosteroid-free remission (CFR).
Results: 64 children were included [32 (50%) male, mean age 14.5 ± 2.8 years, with a median follow-up 24 weeks (IQR 14-38; range 6-116)]; 41 (64%) UC/IBDU and 23 (36%) CD. All were previously treated with anti-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, 6 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 3 minor drug-related adverse events. Overall 5% achieved endoscopic mucosal healing with 9% achieving stool calprotectin<100mcg/gm.
Conclusion: Vedolizumab was safe and effective in this cohort of pediatric refractory IBD. These data support previous findings of slow induction rate of vedolizumab in CD and a trend to be less effective compared to patients with UC.
