Key inclusion & exclusion criteria

Inclusion criteria:
Each potential participant must satisfy all of the following criteria to be enrolled in the study:
General
1. 2 to <18 years of age, inclusive (at the time of the first administration of study intervention at Week I-0) with a body weight =10 kg.
2. Medically stable on the basis of physical examination, medical history, and vital signs, performed at screening. Any abnormalities must be consistent with the underlying illness in the study population and this determination must be recorded in the participant's source documents and acknowledged by the investigator.
3. Criterion modified per Amendment 2
3.1 Medically stable on the basis of clinical laboratory tests performed at screening. If the results of the serum chemistry panel including liver enzymes, other specific tests, or hematology are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate and reasonable for the population under study. This determination must be recorded in the participant's source documents and acknowledged by the investigator.

Crohn's Disease diagnosis and status
4. Criterion modified per Amendment 4
4.1 Have Crohn's disease or fistulizing Crohn's disease with active colitis, ileitis, or ileocolitis, confirmed at any time in the past by endoscopy and histology.
5. Criterion modified per Amendment 4
5.1 i. Must have moderately to severely active Crohn's disease (as defined by a baseline PCDAI score >30)
ii. Have ileocolonoscopy with evidence of active Crohn's disease defined as the presence of ulceration (which is equal to SES-CD score =3) during screening into the study*
*If unable to evaluate ulceration due to stricture or inadequate bowel preparation, at least one of the following criteria may instead be applied:
a. An abnormal CRP (>0.3mg/dL or 3.0 mg/L at screening)
OR
b. Fecal calprotectin of =250 mg/kg or =250 µg/g at screening

Allowed concomitant or prior medical therapies for Crohn's disease
6. Prior or current medication for Crohn's disease must include at least one of the following:
Have received biologic therapy for the treatment of pediatric Crohn's disease and have had an appropriate washout duration prior to first administration of study intervention and have a documented history of failure to respond to or not tolerate treatment.
OR
Be naïve to biologic therapy and have a prior or current Crohn's disease medication history that includes at least 1 of the following:
a. Inadequate response to or failure to tolerate current treatment with oral or IV corticosteroids or immunomodulators (6-MP, AZA, or MTX)
OR
b. History of failure to respond to, or tolerate, at least 1 of the following therapies: oral or IV corticosteroids or immunomodulators (6-MP or AZA or MTX)
OR
c. History of corticosteroid dependence (ie, an inability to successfully taper corticosteroids without a return of the symptoms of Crohn's disease)
OR
d. Have required more than 3 courses of oral or IV corticosteroids in the past year.
7. Must meet concomitant medication criteria prior to the first administration of study intervention:

Corticosteroids
a. If receiving budesonide or beclomethasone dipropionate, the dose must have been stable for at least 2 weeks prior to Week I-0.
7.1 Criterion modified per Amendment 2
b. If receiving oral corticosteroids other than budesonide or beclomethasone dipropionate, the dose must be =1.5 mg/kg/day pred
Exclusion criteria:
Any potential participant who meets any of the following criteria will be excluded from participating in the study:

Crohn's disease diagnosis and status
1. Has complications of Crohn’s disease such as symptomatic strictures or stenosis, short gut syndrome, or any other manifestation that might be anticipated to require surgery, that 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.
2. 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. Participants with active fistulas may be included if there is no anticipation of a need for surgery and there are currently no abscesses identified.
3. Has had any kind of bowel resection within 6 months or any other intra-abdominal surgery within 3 months prior to Week I-0.
4. Presence of a stoma.

Concomitant or Previous Medical Therapies Received
5. Has received any of the following prescribed medications or therapies within the specified period:

mirikizumab (formerly LY3074828), and risankizumab.
c. Has ever received thalidomide or related agents.
d. Has received natalizumab within 12 months of Week I-0.

f. Has received vedolizumab without appropriate washout period prior to Week I-0.
g. Has received other immunomodulatory agents (eg, 6-thioguanine [6-TG], cyclosporine, tacrolimus, sirolimus, or mycophenolate mofetil) within 8 weeks prior to Week I-0.
h. Has received anti-TNFa biologic agents without an appropriate washout period prior to Week I-0.
i. Has used any investigational intervention within 4 weeks prior to Week I-0 or within 5 half-lives of the investigational intervention, whichever is longer.
j. Has used apheresis (ie, Adacolumn apheresis, Cellsorba apheresis) within 2 weeks prior to Week I-0.
k. Have used laxatives, except preparations for endoscopy or other procedures, within 1 week prior to screening procedures.
l. Has initiated enteral nutrition therapy <3 weeks prior to the first administration of study intervention at Week I-0. (Participants who are on a stable regimen =2 weeks prior to the anticipated first administration of study intervention at Week I-0 may be considered for enrollment.
m. Has an indwelling catheter.
n. Is on total (complete) or partial (supplemental) parenteral nutrition or anticipated to require during enrollment in the study. If recently on total
(complete) or partial (supplemental) parenteral nutrition, much have stopped therapy at least <3 weeks before baseline.
