Brief summary

The purpose of this study is to evaluate whether trough serum infliximab concentrations at the time of loss of clinical response will identify pediatric participants with inflammatory bowel disease (IBD) who would benefit (regain clinical response) from dose escalation above the currently approved dose \[5 milligram (mg)/kilogram (kg) every 8 weeks (q8wk)\] and the safety of that dose escalation.

Detailed description

This is a multicenter (when more than one hospital or medical school team work on a medical research study), prospective (study following participants forward in time), open-label (all people know the identity of the intervention) study of infliximab in pediatric participants with inflammatory bowel disease. The study consists of 3 Phases: screening Phase (up to 4 weeks), open-label treatment Phase (56 weeks) and follow up safety Phase (8 weeks). The duration of participation in the study for each participant is approximately up to 68 weeks (including screening period). Participants' efficacy and safety outcomes will be monitored throughout the study.

Interventions

DRUGInfliximab

Participants in the dose escalation group will escalate dose from infliximab 5 mg/kg q8w to 10 mg/kg q8w at the time of loss response. Participants in the reference group will be maintained on infliximab 5 mg/kg q8w.

Clinical Response at Week 16 After Dose Escalation as Evaluated by Pediatric Crohn's Disease Activity Index (PCDAI) in Crohn's Disease (CD) ParticipantsWeek 16Clinical response was defined as Crohn's disease (CD) participants with decrease from baseline in PCDAI of greater than or equal to (\>=) 15 points with total score of less than or equal to (\<=) 30 points. PCDAI includes three history items (abdominal pain, number of liquid stools, general wellbeing), five physical examination items (abdominal examination, perirectal disease, extraintestinal manifestations, weight, height), and three laboratory tests (hematocrit, albumin, erythrocyte sedimentation rate). Items are scored on a three-point scale (zero, 5, or 10 points) except for hematocrit and erythrocyte sedimentation rate which are scored as zero, 2.5 or 5 points. PCDAI scores can range from zero to 125 with higher scores indicating more active disease. Data for this OM was planned to be analyzed for Dose escalation (DE) group only.
Clinical Response at Week 16 After Dose Escalation as Evaluated by Mayo Score in Ulcerative Colitis (UC) ParticipantsWeek 16Clinical Response as per Mayo score was defined as decrease from baseline in partial Mayo score of \>= 2 points and \>= 30 percent (%) and decrease in rectal bleeding sub-score by \>= 1 point or achievement of an absolute sub-score of less than or equal to (\<=) 1 point (for UC participants). A Partial Mayo Score which is Mayo score without endoscopy ranges from 0 (normal or inactive disease) to 9 (severe disease) and calculated as the sum of 3 subscores (stool frequency, rectal bleeding and physician's global assessment \[PGA\]) with each ranging from 0 to 3 (0=normal, 1=mild, 2=moderate, 3=severe). Data for this OM was planned to be analyzed for the DE group only.
