Trial Summary

Do I need to stop my current medications to join the trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug ustekinumab for pediatric Crohn's disease?

Research shows that ustekinumab, a drug used for Crohn's disease, led to clinical remission in about 50% of patients after one year. Additionally, a 10-year-old girl with Crohn's disease achieved remission without adverse effects after using ustekinumab, suggesting it may be effective and safe for children.12345

Is ustekinumab safe for children with Crohn's disease?

Ustekinumab has been used in children with Crohn's disease, and studies have shown it to be generally safe, with no serious side effects like infusion reactions or increased infections reported in some cases.12346

How is the drug ustekinumab unique for treating pediatric Crohn's disease?

Ustekinumab is unique because it targets specific proteins (interleukin-12 and interleukin-23) involved in inflammation, offering a different approach than traditional treatments like corticosteroids or TNF antagonists. It is administered as an intravenous induction followed by subcutaneous maintenance, and has shown promise in children who have not responded to other treatments.12347

What is the purpose of this trial?

This trial is testing a medication that reduces inflammation in children with severe Crohn's disease. The goal is to see if it can help them get better and stay better. The study will also check how safe the medication is and how it works in the body.

Eligibility Criteria

This trial is for children with moderately to severely active Crohn's disease, confirmed by endoscopy and histology. They must have a PCDAI score >30 and show ulceration or elevated CRP/fecal calprotectin levels. Girls who can have babies must test negative for pregnancy. Kids with certain infections, recent investigational drug use, Crohn's complications that might need surgery, cancer history, or serious organ problems can't join.

Inclusion Criteria

I am a woman who can have children and have tested negative for pregnancy.
I have Crohn's disease with active inflammation, confirmed by a past endoscopy.
I have active Crohn's disease with a recent test showing ulcers in my intestines.

Treatment Details

Interventions

  • Placebo
  • Ustekinumab
Trial Overview The study tests Ustekinumab in kids to see if it helps them reach and maintain remission from Crohn's symptoms compared to a placebo (a treatment with no active drug). It also looks at the safety of the drug and how it moves through and out of their bodies over time.
Participant Groups
3Treatment groups
Experimental Treatment
Group I: Ustekinumab Subcutaneous (SC) Every 8 Weeks (q8w): Maintenance PeriodExperimental Treatment2 Interventions
Participants will receive SC administration of ustekinumab q8w based on BSA (mg/m\^2) or weight-tiered induction dose (mg/kg) at maintenance weeks (Weeks M)-0, M-8, M-16, M-24, M 32, and M-40 and matching placebo at Weeks M-12 and M-36 to maintain the blind.
Group II: Ustekinumab SC Every 12 Weeks (q12w): Maintenance PeriodExperimental Treatment2 Interventions
Participants will receive SC administration of ustekinumab q12w based on BSA (mg/m\^2) or weight-tiered induction dose (mg/kg) at Weeks M-0, M-12, M-24, M-36 and matching placebo at Weeks M-8, M-16, M-32, and M-40 to maintain the blind.
Group III: Open- Label Ustekinumab Intravenous (IV): Induction PeriodExperimental Treatment1 Intervention
All participants will receive a single IV administration of ustekinumab at induction Week 0 (I-0) based on body surface area (BSA) (milligram per meter square \[mg/m\^2\]) or weight-tiered induction dose (milligram per kilogram \[mg/kg\]).

Findings from Research

In a study of 36 adults with Crohn's disease, 61% responded to ustekinumab treatment after one year, but no distinct gene expression signature was found to predict response, indicating that more research is needed to identify reliable biomarkers.
Among nonresponders, an increased inflammatory response was observed, with 68 genes linked to cytokine activity and chemokine receptor binding, suggesting that these pathways may play a role in treatment resistance.

In a Phase 1 study involving 44 children with moderately to severely active Crohn's disease, ustekinumab showed pharmacokinetics similar to adults, but lower serum levels were observed in patients weighing less than 40 kg, indicating a need for adjusted dosing in this group.
The study found that 22% of patients on the lower dose and 29% on the higher dose achieved clinical remission by Week 16, with a notable 73% reporting at least one adverse event, suggesting that while ustekinumab is generally safe, careful monitoring is necessary.

Ustekinumab was effective in achieving clinical and endoscopic remission in a 10-year-old girl with Crohn's disease after 75 weeks of treatment, indicating its potential as a first-line biological agent for pediatric patients.
The treatment was well-tolerated with no reported adverse events, suggesting that ustekinumab is a safe option for managing pediatric inflammatory bowel disease.
