What side effects are associated with this type of intervention?

Common treatments for Ulcerative Colitis include biologics like Guselkumab (IL-23 inhibitor), 5-aminosalicylic acid (5-ASA) agents, and glucocorticoids. Biologics such as Guselkumab can cause nasopharyngitis, headache, and injection site reactions. 5-ASA agents, including mesalamine and sulfasalazine, may lead to nausea, headache, fever, rash, pancreatitis, and pneumonitis. Glucocorticoids, used for short-term symptom relief, can result in systemic side effects like adrenal suppression, weight gain, hypertension, and increased risk of infections.

What prior FDA approvals exist?

The FDA has approved several biologic treatments for moderate to severe Ulcerative Colitis. These include anti-TNF agents like infliximab (Remicade) and adalimumab (Humira), which target tumor necrosis factor-alpha (TNF-α). Additionally, vedolizumab (Entyvio), an integrin receptor antagonist, and ustekinumab (Stelara), an interleukin-12 and interleukin-23 inhibitor, have been approved. Ustekinumab is particularly similar to Guselkumab, as both target the IL-23 pathway, although Guselkumab specifically inhibits IL-23. These biologics have shown efficacy in reducing inflammation and maintaining remission in patients with Ulcerative Colitis.

What other types of research exist?

Promising novel alternatives to Guselkumab for Ulcerative Colitis patients include Ustekinumab (an IL-12/23 inhibitor) and Vedolizumab (an integrin receptor antagonist). Both have demonstrated efficacy in treating UC and are viable options for patients seeking alternative treatments.

Summary

"This trial aims to see how well guselkumab works in children with moderate to severe ulcerative colitis after they have already responded well to the initial treatment."

Who is the study for?

This trial is for children and teenagers with moderately to severely active ulcerative colitis, a type of inflammatory bowel disease. Participants must have shown some response to earlier treatment phases to qualify.Check my eligibility

What is being tested?

The study tests the effectiveness of Guselkumab, a medication, in young patients with ulcerative colitis. It compares Guselkumab against a placebo (a substance with no therapeutic effect) over time.See study design

What are the potential side effects?

Guselkumab may cause side effects like infections, allergic reactions, headaches, stomach pain, and injection site reactions. The severity can vary from person to person.

Experimental Treatment

Group I: Open-label Maintenance Phase: Guselkumab SCExperimental Treatment1 Intervention

Week 12 non-responders will enter an open-label maintenance phase to receive guselkumab SC dosing regimen based on their body weight up to Week 56.

Group II: Open-label Induction Phase: Guselkumab Subcutaneously (SC)Experimental Treatment1 Intervention

Participants will receive a guselkumab dose SC based on their BW during the 12-week open-label induction phase.

Group III: Open-label Induction Phase: Guselkumab Intravenously (IV)Experimental Treatment1 Intervention

Participants will receive a guselkumab dose IV based on their body weight (BW) during the 12-week open-label induction phase.

Group IV: Double-blind Maintenance Phase: Guselkumab SC or Guselkumab SC and Placebo SCExperimental Treatment2 Interventions

At the end of the induction phase, Week 12 responders will be randomized into the double-blind maintenance phase to receive a guselkumab dose SC based on their BW or a guselkumab dose SC based on their BW and placebo SC up to Week 56.

Other Research

The most common treatments for Ulcerative Colitis (UC) include biologic therapies, 5-aminosalicylates (5-ASA), and corticosteroids. Biologic therapies, such as Guselkumab, work by inhibiting specific components of the immune system. Guselkumab targets Interleukin-23 (IL-23), a cytokine involved in inflammatory processes, thereby reducing inflammation and helping to maintain remission in UC patients. Anti-TNF agents like infliximab and adalimumab block tumor necrosis factor-alpha (TNF-α), another key cytokine in inflammation. 5-ASA drugs, such as mesalamine, act locally in the colon to reduce inflammation. Understanding these mechanisms is crucial for UC patients as it helps tailor treatment plans to effectively manage symptoms and maintain long-term remission.
