AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for children and teenagers with moderately to severely active ulcerative colitis or Crohn's disease. They will get vedolizumab under the skin for up to 34 weeks.
- Age
- 2 Years to 17 Years
- Sex
- All sexes can join.
- Disease stage
- Ulcerative colitis or Crohn's disease diagnosed at least 1 month before screening, with moderately to severely active disease. Ulcerative colitis must reach beyond the rectum.
- Earlier treatment
- Must have failed, lost response to, or not tolerated at least 1 of: corticosteroids, immunomodulators, or TNF-α antagonist therapy. Must not have had vedolizumab or anti-integrin drugs before.
- Biomarker or test result
- Ulcerative colitis: modified Mayo score of 5 to 9 with Mayo endoscopic subscore of ≥2. Crohn's disease: PCDAI >30 and SES-CD >6 (or ≥4 if disease is confined to terminal ileum).
Main reasons for not taking part
- Previous vedolizumab or anti-integrin treatment
- Active or latent tuberculosis
- Hepatitis B infection (positive HBsAg or HBcAb)
- Immune system deficiency, such as HIV infection or organ transplantation
- Surgery needed now or expected, or earlier colectomy, ileostomy or colostomy

An Open-Label, Phase 3 Study to Evaluate the Pharmacokinetics, Safety, and Immunogenicity of Vedolizumab Subcutaneous in Pediatric Subjects With Moderately to Severely Active Ulcerative Colitis or Crohn's Disease Who Achieved Clinical Response Following Open-Label Vedolizumab Intravenous Therapy
The main aim of this study is to learn how the body of a child or teenager with moderately to severely active ulcerative colitis (UC) or Crohn's disease (CD) processes vedolizumab (pharmacokinetics) given just under the skin subcutaneously (SC).
The participants will be treated with vedolizumab for up to 34 weeks.
During the study, participants will visit their study clinic several times.
Inclusion: The participant weighs ≥10 kg at the time of screening and enrollment into the study; Participants with UC or CD diagnosed at least 1 month before screening. Participants with moderately to severely active disease defined as:; Participants with UC: a modified Mayo score of 5 to 9 (sum of Mayo endoscopic subscore, stool frequency subscore, and rectal bleeding subscore) with a Mayo endoscopic subscore of ≥2 (with the presence of mucosal friability excluding an endoscopic subscore of 1 and mandating a score of at least 2). (The results of screening endoscopy should be applied.); Participants with CD: a pediatric Crohn's disease activity index (PCDAI) >30 and a simple endoscopic score for Crohn's disease (SES-CD) >6 (or an SES-CD ≥4 if disease is confined to terminal ileum) at screening endoscopy; Participants who have failed, lost response to, or been intolerant to treatment with at least 1 of the following agents: corticosteroids, immunomodulators (for example, azathioprine [AZA], 6-mercaptopurine [6-MP], methotrexate [MTX]), and/or tumor necrosis factor (TNF)-α antagonist therapy (for example, infliximab, adalimumab); Participants with evidence of UC extending proximal to the rectum (that is, not limited to proctitis), at a minimum; Participants with extensive colitis or pancolitis of >8 years' duration or left-sided colitis of >12 years' duration must have documented evidence of a negative surveillance colonoscopy within 12 months before screening; Participants with vaccinations that are up-to-date based on the countrywide accepted schedule of childhood vaccines.
Exclusion: Participants who have had previous exposure to approved or investigational anti-integrins, including but not limited to, natalizumab, efalizumab, etrolizumab, or abrilumab (AMG 181); or mucosal addressin cell adhesion molecule-1 (MAdCAM-1) antagonists (ontamalimab), or rituximab; Participants who have had prior exposure to vedolizumab; The participant has received any live vaccinations within 30 days before first dose of study drug; Participants who currently require surgical intervention or are anticipated to require surgical intervention for UC or CD during this study; Participants with hypersensitivity or allergies to vedolizumab or any of its excipients; Participants with active cerebral/meningeal disease, signs/symptoms or history of progressive multifocal leukoencephalopathy (PML) or any other major neurological disorders; Participants who have had subtotal or total colectomy or have a jejunostomy, ileostomy, colostomy, ileo-anal pouch, known fixed stenosis of the intestine, short bowel syndrome, or >3 small intestine resections; Participants with clinical features suggesting monogenic very early-onset inflammatory bowel disease (IBD); Participants with active or latent tuberculosis (TB); Participants with evidence of positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb). Hepatitis B virus (HBV) immune subjects (that is, HBsAg negative and hepatitis B surface antibody [anti-HBs]-positive) may, however, be included; The participant has any identified congenital or acquired immunodeficiency (for example, common variable immunodeficiency, human immunodeficiency virus [HIV] infection, organ transplantation); Participants with a current diagnosis of indeterminate colitis; Participants with positive stool studies for ova and/or parasites or stool culture at screening visit; Participants with positive Clostridioides difficile (C difficile) stool test at screening visit.
