E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate whether trough serum infliximab concentrations at the time of loss of clinical response will identify pediatric patients with IBD who would benefit (regain clinical response) from dose escalation above the currently approved dose (5 mg/kg every 8 weeks [q8wk]).
Overall safety will be assessed throughout the duration of the study. |
|
E.2.2 | Secondary objectives of the trial |
- Identify disease characteristics associated with maintenance of sustained clinical response in patients after dose escalation
- Evaluate the rate of serious adverse events in patients who receive an increased dose of infliximab due to loss of response (Dose Escalation Group) relative to the rate of serious adverse events in those patients in response who are maintained on infliximab 5 mg/kg q8wk (Reference Group) |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Must have a biopsy-confirmed diagnosis of Crohn’s disease (CD) or ulcerative colitis (UC) prior to study entry
- Must meet concomitant medication stability criteria as specified in protocol
- Is considered eligible according to the tuberculosis (TB) Screening criteria specified in protocol
- Must have negative stool results for enteric pathogens. Stool studies must include a stool culture and Clostridium difficile toxin assay. These must have been performed during Screening or the current episode of disease exacerbation as long as the stool studies were performed within 4 months prior to the first administration of infliximab at Week 0
- Must have screening laboratory test results as specfied in the protocol
- Must be up to date with all immunizations in agreement with current local immunization guidelines for immunosuppressed participants prior to Screening
- Must not have discontinued infliximab therapy |
|
E.4 | Principal exclusion criteria |
- Must not require, or must not have required, within the 2 months prior to Screening, surgery for active gastrointestinal bleeding, peritonitis, intestinal obstruction, or intraabdominal or pancreatic abscess requiring surgical drainage, or other conditions possibly confounding the evaluation of benefit from infliximab treatment
- Must not have presence or history of colonic or small bowel obstruction within 6 months prior to Screening, confirmed by objective radiographic or endoscopic evidence of a stricture with resulting obstruction (example, dilation of the colon or small bowel proximal to the stricture on barium radiograph or an inability to traverse the stricture at endoscopy)
- Must not have local manifestations of CD, such as fistulae, strictures, abscesses, or other disease complications for which surgery might be indicated. Enterocutaneuous fistulae for which surgery is not indicated, are allowed
- Must not have presence of a stoma
- Must not have documented short bowel syndrome (more than 100 centimeter in total of small bowel resected) |
