Pharmacokinetic Infliximab Data in Pediatric Crohn's Disease

Rationale: Crohn's disease (CD) is a chronic, debilitating inflammatory bowel disease (IBD) which is diagnosed during childhood in up to one in ten patients. The use of anti-tumor necrosis factor (TNF)-α agents has significantly ameliorated CD management. Infliximab (IFX) is the first anti-TNF-α agent registered for pediatric CD. The current dosing recommendation of IFX is extrapolated from adult studies, and it is a weight-based dose (5 mg/kg) delivered during induction (infusion at weeks 0, 2, and 6) and maintenance (every 8 weeks). However, pediatric patients have a 25-40% lower drug exposure compared to adults, particularly children under 10 years of age, resulting in diminished efficacy and an increased risk of developing a complicated disease course. The investigators hypothesize that an intensified IFX induction scheme (instead of the current dosing recommendation) is more effective in the treatment of pediatric CD patients. Objective: The primary study objective of our study is to assess the efficacy of an IFX intensified induction scheme vs. a standard dosing schedule in improving drug exposure without treatment escalation in pediatric CD patients. Secondary objectives are clinical and biochemical remission without treatment escalation, development of antibodies to IFX (ATI) and adverse reactions. Study design: An international, multicenter, prospective, open-label trial. Study population: Anti-TNF-α naïve children (age 1-15 years) with CD and an indication to star…
