|Main objective of the trial
1. To evaluate the efficacy of ustekinumab dosing in inducing clinical remission in pediatric participants with moderately to severely Crohn's disease
2. To evaluate the safety profile of ustekinumab in pediatric participants with moderately to severely active Crohn's disease.

|Trial contains a sub-study
|Full title, date and version of each sub-study and their related objectives
|An optional Exposure Optimization Substudy, as described in Appendix 17 of the Protocol, for induction nonresponders who have a low steadystate, 8 weeks post-dose ustekinumab concentration, and for induction responders and delayed responders who lose response during maintenance and have a low steady-state, 8 weeks post-dose ustekinumab concentration.
- To determine if a q4w dose regimen in participants who have induction nonresponse or LOR and low 8-week steady-state ustekinumab trough concentrations during maintenance will result in steady-state ustekinumab trough exposures ≥1.4 ug/mL
- To evaluate the safety and immunogenicity of ustekinumab administered q4w in participants who have induction nonresponse or LOR and low ustekinumab exposure
|Principal inclusion criteria
|Each potential participant must satisfy all of the following criteria to be enrolled in the study:
