Clinical Trial Summary

The purpose of the study is to assess whether a proactive therapeutic drug monitoring strategy, introduced early during treatment, improves Infliximab (IFX) durability, efficacy and safety in children and young adults with inflammatory bowel disease. Patients with an indication to receive IFX, based on current clinical practice recommendations, will receive the drug either based on IFX concentrations determined before every IFX infusion, starting from the third infusion, or at standard dosing. Approximately 90 patients will be included in this research study. Patients enrolled will be in the study for approximately 12 months.


Description:

Inflammatory Bowel Disease (IBD) are relapsing disorders with progressive bowel damage leading to long-term disability. Infliximab (IFX), is a highly effective and commonly used biologic in IBD. However, up to 40% of patients do not respond to treatment or lose response over time. Low-serum IFX concentrations and the development of antibodies to IFX (ATI) are two major factors affecting IFX efficacy, durability and safety. Standard IFX dose is administered as an IV (in the vein) infusion at 5 mg/kg in a 0, 2, and 6 weeks induction regimen followed by a maintenance regimen with infusions every 8 weeks. This standard dosing is extrapolated from adult studies. IFX has a highly variable pharmacokinetic and pharmacodynamics that is dependent on body weight, disease extent, levels of inflammation and the presence of ATI. In children and young adults with IBD all these factors often result in low-serum IFX concentrations. Proactive therapeutic drug monitoring, consists in the measurement of drug concentrations on patient's blood, in order to adjust the following administrations (dosing or interval) and maintain a desired concentration of the medication in the body. This study seeks to determine whether a proactive therapeutic drug monitoring strategy can improve IFX durability, efficacy and safety in children and young adults with IBD. The study will involve approximately 90 patients, aged 6 to 17 years, with IBD. All the patients enrolled in the study will receive IFX at 5mg/kg at week 0, 2 and 6. At week 6 patients will be randomly assigned to receive IFX treatment either based on IFX concentrations determined before every IFX infusion (intervention group) or at standard dosing (control group). Patients will participate in the study for 54 weeks (approximately 12 months) or until IFX discontinuation. During the study, patients will visit the study center at the time of every IFX infusion or in case of disease flares.

Outcome

Type Measure Description Time frame Safety issue
Primary Frequency of IFX discontinuation or need for treatment intensification due to non-response or LOR during the first year of treatment. Composite outcome. Treatment intensification is defined as adjunction of rescue therapies, including corticosteroids systemic or topical, azathioprine (AZA), methotrexate (MTX), 5-aminosalicylate (5-ASA) systemic or topical, or rescue IFX escalation or surgery; treatment response is defined as a decrease in Pediatric Crohn's Disease Activity Index (PCDAI) by 12.5 point or in Pediatric Ulcerative Colitis Activity Index (PUCAI) by 10 points with decrease in C reactive protein (CRP) by 50% after induction, evaluated between 12-14 weeks; loss of response (LOR) is defined as PCDAI >= 10 or PUCAI > 10 with CRP > 0.5mg/dl and/or fecal calprotectin (FC) >250 microg/g in a patient who previously responded to induction treatment. 54 weeks
Secondary Cumulative probability of IFX discontinuation Time to IFX discontinuation 54 weeks
Secondary Cumulative probability of Loss of Response Time to Loss of Response (LOR), with LOR defined as PCDAI >= 10 or PUCAI > 10 with CRP > 0.5 mg/dl and/or FC >250 microg/g in a patient who previously responded to induction treatment. 54 weeks
Secondary Frequency of subtherapeutic IFX concentrations Subtherapeutic IFX concentration is defined as IFX concentration at trough < 5 microg/ml (or <10 microg/ml in perianal CD) during maintenance treatment. 54 weeks
Secondary Frequency of Anti-Infliximab Antibodies Evaluation of Anti-Infliximab Antibodies 54 weeks
Secondary Frequency of infusion reactions Infusion reactions are defined as reactions that develop during the course of the infusion or within 1-2h of its completion. 54 weeks
Secondary Frequency of endoscopic remission Endoscopic remission is defined in patients with Crohn's Disease as a Simple Endoscopic score for Crohn's Disease (SES-CD score) less than or equal to (<=) 2 and in patients with Ulcerative Colitis as a Mayo sub-score <= 1 54 weeks
Secondary Frequency of patients with treatment response at the end of induction between 12 and 14 weeks Treatment response is defined as a decrease in PCDAI by 12.5 point or in PUCAI by 10 points with decrease in CRP by 50% compared to baseline Week 14
Secondary Frequency of patients with clinical remission at 14 weeks Clinical remission is defined as PCDAI <10 or PUCAI <10 Week 14
Secondary Frequency of clinical and biochemical remission at week 14 Clinical and Biochemical remission is defined as PCDAI <10 or PUCAI <10 with CRP < 0.5 mg/dl and FC < 250 microg/g Week 14
