What this trial studies

This study aims to assess the effectiveness of guselkumab, administered both subcutaneously and intravenously, in pediatric patients suffering from moderately to severely active ulcerative colitis. Participants must have shown a positive response to induction therapy and will be evaluated at the end of maintenance therapy. The study will involve a thorough screening process to confirm the diagnosis and severity of the condition using established clinical criteria.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged 10 kg or more with a documented diagnosis of moderately to severely active ulcerative colitis.

Not a fit: Patients with mild ulcerative colitis or those who do not meet the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of ulcerative colitis in children, leading to better health outcomes.

How similar studies have performed: Previous studies have shown promising results with similar biologic therapies for ulcerative colitis, indicating potential for success with this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Weight greater than or equal to (\>=) 10 kilogram (kg) at the time of consent for screening
* A pathology report to support a documented diagnosis of Ulcerative Colitis (UC) must be available in the source documents. There is no maximum duration for which a participant needs to be diagnosed with UC. If the pathology report to support a documented diagnosis of UC is not available in the source documents, the screening endoscopy with biopsies (obtained within 3 weeks before first study intervention administration) needs to support the diagnosis of UC.
* Moderately to severely active UC, defined by a baseline modified Mayo (without physician's global assessment) score of 5 through 9 inclusive, with a screening Mayo endoscopy subscore \>= 2 as determined by a central review of the video of the endoscopy
* Medically stable based on 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
* Participants must have had an inadequate response and/or intolerance to biologic therapy and/or conventional therapies or be dependent upon corticosteroids

Exclusion Criteria:

* Have UC limited to the rectum only or to less than (\<) 20 centimeter of the colon
* Presence of a stoma
* Has had any kind of bowel resection within 6 months or any other intra-abdominal surgery within 3 months of baseline
* Have severe colitis or have evidence of Crohn's Disease (CD)
