A Long-Term Extension Study of Vedolizumab in Children and Teenagers With Ulcerative Colitis (UC) or Crohn's Disease (CD)

Ulcerative Colitis Clinical Trial

Official title: A Phase 3b Extension Study to Evaluate the Long-term Safety of Vedolizumab Subcutaneous in Pediatric Subjects With Ulcerative Colitis or Crohn's Disease

Status Not yet recruiting

Clinical Trial Summary

The main aim of this study is to learn about medical problems (adverse events) if vedolizumab subcutaneously (SC) is given to a child or teenager with UC or CD for a long time. Other aims are to understand if the long time use of vedolizumab SC has an impact on the time period until hospital visits because of bowel swelling (inflammation) are needed and has an impact on the quality of life of children and teenagers who received vedolizumab SC.

In this study, participants who responded well to the treatment with vedolizumab SC in the parent study (VedolizumabSC-3003 [NCT06100289]) will continue to be treated with vedolizumab SC. Participants who did not respond well to the treatment with vedolizumab SC in the parent study or who received corticosteroids in the last 4 weeks of the parent study will not receive vedolizumab SC in this study but will be followed for up to 2 years after the last treatment with vedolizumab SC in the parent study.

During the study, participants will visit their study clinic several times.

Clinical Trial Description

The drug being tested in this study is Vedolizumab SC. Vedolizumab SC is being tested to treat pediatric participants with moderate to severe active UC or CD. This study will look at the long-term safety profile in pediatric participants who take vedolizumab SC.

The study will enroll approximately 70 participants. This extension study consists of a treatment cohort and an observational cohort. Participants will continue receiving the same dose and frequency of vedolizumab SC that was received at the last dose of the parent study VedolizumabSC-3003 (NCT06100289).

For the Treatment cohort participants will receive vedolizumab SC injection on Day 1 based on their weight as:

• Participants with greater than or equal to (>=) 30 kilogram (kg) weight, Vedolizumab 108 milligram (mg) once every two weeks (Q2W)

• Participants with >= 10 kg to less than (<) 30 kg weight, Vedolizumab 108 mg once every four weeks (Q4W)

This multi-center trial will be conducted globally. The overall time to participate in this study is up to 5 years from the first dose in the study. Participants in the treatment cohort will have a follow-up safety visit of 18 weeks after their last dose of study drug. Participants who will not be eligible for the treatment cohort will be enrolled in the observational cohort and will be followed for approximately 2 years after the last dose of vedolizumab SC received during Study VedolizumabSC-3003 (NCT06100289). ;
