ADA is now often used in first line due to its efficacy and tolerability, but a loss of response (LOR) can occur over time. The aim was to assess the efficacy of IFX as second line therapy after LOR or intolerance to ADA in pediatric CD patients at 1 year.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a retrospective and multicenter study in France among the \u201cGETAID p\u00e9diatrique\u201d centers between April 2019 and April 2022. CD patients under 18 years old and treated with IFX after ADA failure or intolerance were included. We collected anthropometric, clinical, and biological data at baseline (start of IFX), at 6 and 12 months. Clinical remission was defined by a Weighted Pediatric CD Activity Index (wPCDAI) score less than 12.5 points.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 32 patients included in our study, 27 (84.4%) were still on IFX at 12 months of the switch. Among them, 13 had discontinued ADA because of a LOR, 12 for insufficient response and 2 due to primary nonresponse. At M12, 22 patients were in corticosteroid free clinical remission (68.7%). Under IFX, the wPCDAI decreased over time (47.5\u2009\u00b1\u200924.1, 16.6\u2009\u00b1\u200921.2 and 9.7\u2009\u00b1\u200919.0 at M0, M6 and M12 respectively). The only factor associated with clinical remission at 12 months was absence of perianal disease at the end of the IFX induction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>IFX is effective in maintaining remission at 1 year in pediatric CD patients experiencing a LOR or intolerance with ADA, and IFX could be an interesting therapeutic choice instead of other biologics in this
