Be a pediatric subject 2 to less than (\<) 18 years old in the US, 6 to \<18 years old elsewhere, of either gender with a body weight of greater than or equal to (\>=) 10 kilogram (kg)
Have Crohn's disease (CD) or fistulizing CD of at least 3 months duration, with active colitis, ileitis, or ileocolitis, confirmed at any time in the past by radiography, histology, and/or endoscopy
Must have moderately to severely active CD defined by: Baseline pediatric Crohn's disease activity index (PCDAI) score of greater than (\>)30 and at least one of the following: An abnormal C-reactive protein (CRP) \>0.3 milligram per deciliter (mg/dL) or 3.0 milligram per liter (mg/L) at screening) or fecal calprotectin \>250 milligram per kilogram (mg/kg) at screening or ileocolonoscopy with evidence of active CD (defined as ulcerations in the ileum and/or colon) during screening into this study including at the baseline visit
Prior or current medication for CD must include at least 1 of the following: Current treatment with at least 1 of the following therapies: oral corticosteroids, the immunomodulators azathioprine, 6-MP, or methotrexate, or currently have or have had a history of corticosteroid dependency, or have a history of failure to respond to, or tolerate, at least 1 of the following therapies including oral or IV corticosteroids or the immunomodulators 6-mercaptopurine, azathioprine, or methotrexate,or have required more than 3 courses of oral or IV corticosteroids in the past year
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 study agent
You may not be if
Has complications of CD such as symptomatic strictures or stenosis, short gut syndrome, or any other manifestation that might be anticipated to require surgery, could preclude the use of the PCDAI to assess response to therapy, or would possibly confound the ability to assess the effect of treatment with ustekinumab
Currently has or is suspected to have an abscess. Recent cutaneous and perianal abscesses are not exclusionary if drained and adequately treated at least 3 weeks prior to baseline, or 8 weeks prior to baseline for intra-abdominal abscesses, provided that there is no anticipated need for any further surgery. Participant with active fistulas may be included if there is no anticipation of a need for surgery and there are currently no abscesses identified
Has had any kind of bowel resection within 6 months or any other intra-abdominal surgery within 3 months prior to baseline
Has a draining (that is (i.e.), functioning) stoma or ostomy
Presence or history of any malignancy including presence or history of lymphoproliferative disease including lymphoma, or signs and symptoms suggestive of possible lymphoproliferative disease, such as lymphadenopathy of unusual size or location (example, nodes in the posterior triangle of the neck, infraclavicular, epitrochlear, or periaortic areas), or clinically significant hepatomegaly or splenomegaly
