Summary

This clinical trail intends to evaluate interventions based on the Infliximab trough levels for an individualized therapy adaption for pediatric IBD-patients undergoing anti-TNF-alpha-therapy. Main aim of the individualized strategy is to attain and maintain early disease control in order to keep as many patients as possible in disease remission, and to avoid primary and secondary therapy failure.

Detailed description

Anti TNF-alpha agents such as Infliximab are efficient and safe in treating pediatric IBD-patients. However maintaining the remission and therapeutic response is still a challenge for the practitioner. In addition to a relevant number of primary non-responding patients individual clearance and immunogenic effects lead to secondary loss of response in a significant number of patients. So far these patients are clinically managed by decrease of the infusion interval or increasing the dose. Besides an increased risk for potential side effect a high number of patients need to switch treatment to other biologicals despite interventions. Improved strategies are needed to avoid primary and secondary therapeutic failure, and a promising lead seems to be the individualized therapy. Especially in pediatric IDB-patients with faster turnover of anti-TNF based on a higher metabolism rate new ways of adapting the dose and maintaining therapeutic serum levels are necessary. In this context the role of IFX-trough levels is not fully clear. Previous studies have shown that serum IFX trough levels correlate inversely with the turnover rate and directly to therapeutic response. Thus it is highly desirable to keep trough levels in therapeutic window. In adult patients recent studies have shown advantages in using IFX-trough levels for therapy optimization, leading to better disease control in short and long term. However there is until now no clear evidence that shows benefits for an IFX-target-level approach during the maintenance of therapy. An early therapy optimization from the beginning on with rapid control of mucosal inflammation seems to set the pathway for sustained therapy response and disease remission. We assume a clear benefit for an individualized, IFX-trough-level guided therapy optimization for pediatric IDB-patients and intend to clarify the role of Infliximab trough levels in this planned trial.

Conditions

• Pediatric Crohns Disease

Interventions

Type	Name	Description
DRUG	Infliximab	This is a randomized, prospective, parallel -controlled study, simple blinded and multicenter designed. Study centers are the Department of Child and Adolescent Medicine of the Ernst von Bergmann Hospital, Potsdam, and the Department of Child and Adolescent Medicine of Charité, Berlin. We estimate a sample size of 50 patients per center. Study inclusion begins with given consent of the patient and the legal guardian. Patients will be randomized in control- and intervention group separately for Cohn's disease. An equal age and gender distribution is targeted for both control and intervention group. Sub groups will be formed depending on the time span from completed Infliximab induction to study enrollment (group A\< 6month, group B \< 6 month). Observation period is one year.
