Participants with no clinical response (non-responders) at Week 6 received additional golimumab doses at Weeks 6 and 10 at the discretion of the investigator.

Participants without a partial Mayo response at Week 14 were withdrawn from further treatment and entered a 16-week safety follow-up period after the last dose.

Participants who did not show partial Mayo response at Week 14 either received a further dose escalation to 10 mg/kg q4w (capped at 1 gram) or were withdrawn from the study. At Week 22, participants who received the escalated dose of infliximab 10 mg/kg q4w were required to show a partial Mayo response and who met this criterion continued to receive open-label infliximab 10 mg/kg (capped at 1 gram) q4w through Week 50. After Week 54 evaluations, participants receiving infliximab were withdrawn from study participation and transitioned to local standard of care.","id":"FG001","title":"Group 2: Infliximab"}],"periods":[{"dropWithdraws":[{"reasons":[{"groupId":"FG000","numSubjects":"17"},{"groupId":"FG001","numSubjects":"0"}],"type":"Adverse Event"},{"reasons":[{"groupId":"FG000","numSubjects":"8"},{"groupId":"FG001","numSubjects":"0"}],"type":"Lack of Efficacy"},{"reasons":[{"groupId":"FG000","numSubjects":"1"},{"groupId":"FG001","numSubjects":"1"}],"type":"Lost to Follow-up"},{"reasons":[{"groupId":"FG000","numSubjects":"1"},{"groupId":"FG001","numSubjects":"1"}],"type":"Physician Decision"},{"reasons":[{"groupId":"FG000","numSubjects":"1"},{"groupId":"FG001","numSubjects":"0"}],"type":"Protocol Violation"},{"reasons":[{"groupId":"FG000","numSubjects":"1"},{"groupId":"FG001","numSubjects":"0"}],"type":"Initiated Prohibited Medication"},{"reasons":[{"groupId":"FG000","numSubjects":"1"},{"groupId":"FG001","numSubjects":"0"}],"type":"Withdrawal by Parent/Guardian"},{"reasons":[{"groupId":"FG000","numSubjects":"1"},{"groupId":"FG001","numSubjects":"0"}],"type":"No mucosal healing achieved"},{"reasons":[{"groupId":"FG000","numSubjects":"1"},{"groupId":"FG001","numSubjects":"0"}],"type":"Disease progression"},{"reasons":[{"groupId":"FG000","numSubjects":"37"},{"groupId":"FG001","numSubjects":"12"}],"type":"Ongoing"},{"reasons":[{"groupId":"FG000","numSubjects":"0"},{"groupId":"FG001","numSubjects":"1"}],"type":"Randomized but not treated"}],"milestones":[{"achievements":[{"groupId":"FG000","numSubjects":"69"},{"groupId":"FG001","numSubjects":"15"}],"type":"STARTED"},{"achievements":[{"groupId":"FG000","numSubjects":"69"},{"groupId":"FG001","numSubjects":"14"}],"type":"Treated"},{"achievements":[{"groupId":"FG000","numSubjects":"0"},{"groupId":"FG001","numSubjects":"0"}],"type":"COMPLETED"},{"achievements":[{"groupId":"FG000","numSubjects":"69"},{"groupId":"FG001","numSubjects":"15"}],"type":"NOT COMPLETED"}],"title":"Overall Study"}],"preAssignmentDetails":"Results are currently reported until the primary completion date (21-Nov-2023).
