Study summary

When some people have their large bowel removed, a surgeon can make a "pouch" from part of the small bowel to connect it to the back passage (anus). Pouchitis is when the pouch becomes inflamed (swollen) or infected. The main aim of this study is to find out if vedolizumab improves pouchitis symptoms and pouch inflammation. Other aims include to find out if vedolizumab is well tolerated and if it causes any medical problems (adverse events or side effects) and to look for any changes in the well-being of participants during their treatment with vedolizumab.

This study consists of two parts: Part 1 includes the induction and maintenance periods, and Part 2 includes the continued maintenance period. Participants will receive up to 12 infusions of vedolizumab. In Part 1 of the study, first 3 infusions are in first 6 weeks (Day 1, Week 2 and Week 6). Participants who are getting benefit may continue with the treatment for up to 7.5 months (30 weeks) in the maintenance period for Part 1. After completing treatment with vedolizumab in Part 1, participants will visit their clinic for a health check at Week 34.

Participants who show clinical response at Week 34 will continue to Part 2, receiving vedolizumab every 8 weeks for an additional 40 weeks, starting at Week 38 and ending with the last dose being at Week 78. Final efficacy assessments, including a pouchoscopy will be performed at Week 82.

Read the detailed description

The drug being tested in this study is called vedolizumab. This study will look at the efficacy, safety, tolerability, pharmacokinetics (PK), and immunogenicity of vedolizumab in pediatric participants with active chronic pouchitis.

The study will enroll approximately 30 participants. All the participants will be enrolled in a single treatment group to receive treatment with vedolizumab based on participant's weight mentioned as follows:

  • Participants with body weight greater than or equal to (>=) 30 kilogram (kg) will receive vedolizumab, high dose
  • Participants with body weight greater than (>) 15 to less than (\<) 30 kg will receive vedolizumab, medium dose
  • Participants with body weight 10 to 15 kg will receive vedolizumab, low dose

All participants will receive vedolizumab intravenous infusion at Day 1, and at Weeks 2, 6, 14, 22, and 30. Participants will also receive concomitant antibiotic treatment (ciprofloxacin, metronidazole, or other antibiotics) from Day 1 through Week 2. Participants with clinical response at the end of Part 1 maintenance at Week 34 will continue to Part 2 of the study and will receive vedolizumab intravenous infusion every 8 weeks from Week 38 through Week 78.

This multi-center trial will be conducted globally. The maximum overall duration of the study is up to approximately 2 years. Participants will be followed up for 18 weeks after the last dose of the study drug for safety.

Inclusion criteria

  1. The participant weighs >=10 kg at the time of screening and first dose.
  2. Has active chronic pouchitis, defined by a mPDAI score >=5 assessed using the 3-day average of participant-reported clinical symptoms prior to the screening endoscopy (that is [ie] video pouchoscopy with ) or bowel preparation for the endoscopy and a minimum mPDAI endoscopic subscore of 2 (outside the staple or suture line) and either:

    • >=1 previous episodes of pouchitis within 1 year before the screening visit, with symptoms lasting for at least a total of 4 weeks, treated with >=2 weeks of antibiotic or other prescription therapy (ie, other antibiotics, probiotics, immunomodulators, or anti-tumor necrosis factor [TNFs] within 1 year before screening). Or
    • Have had an inadequate response with, or lost response to, or be intolerant to antibiotic therapy (ie, requiring maintenance antibiotic therapy taken for >=4 weeks immediately before the baseline endoscopy visit or not able to receive or continue antibiotic treatment due to intolerance or other ).
  3. The participant is aged 2 to 17 years, inclusive, at the time of screening and first dose.
  4. The participant has a history of proctocolectomy and ileal pouch-anal anastomosis (IPAA) as treatment for ulcerative colitis (UC), Crohn's disease (CD), familial adenomatous polyposis (FAP), or other underlying conditions, such as Hirschsprung's disease, for which construction of a pouch was medically indicated, completed at least 1 year before the screening visit.

Exclusion criteria

Exclusion Criteria:

The exclusion criteria are divided into 3 categories: active chronic pouchitis exclusion criteria, infectious disease exclusion criteria, and general exclusion criteria.

Active Pouchitis Exclusion Criteria:

  1. Has symptoms believed to be predominantly due to irritable pouch syndrome.
  2. Has isolated cuffitis.
  3. Is found to have dysplasia at the screening endoscopy.
  4. Has mechanical complications of the pouch (for example [e.g.] pouch stricture or pouch fistula).
  5. Currently requires or has a planned surgical intervention during the study.
  6. Has a diverting stoma.

    Infectious Disease Exclusion Criteria:

  7. Has evidence of an active infection (e.g. sepsis, cytomegalovirus [CMV], or listeriosis) during screening.
  8. Had a infection (e.g. pneumonia, pyelonephritis, coronavirus disease 2019 [COVID-19]) within 35 days before first dose of study drug.
  9. Has active or latent tuberculosis (TB), as evidenced by a diagnostic TB test performed within 3 months of screening or during the screening period that is positive, as defined by:

    • A positive QuantiFERON test or 2 successive indeterminate QuantiFERON tests, or
    • A TB skin test reaction >=5 millimeter (mm). NOTE: If participant have received Bacillus Calmette-Guérin vaccine, then a QuantiFERON TB Gold test should be performed instead of the TB skin test.

    NOTE: Participants with documented previously treated TB with a negative QuantiFERON test can be included in the study.

  10. Has evidence of positive surface antigen (HBsAg) or hepatitis B core antibody (HBcAb). Hepatitis B virus (HBV) immune participants (e.g. HBsAg negative and hepatitis B antibody positive) may, however, be included.

    NOTE: If a participant tests negative for HBsAg, but positive for HBcAb, the participant would be considered eligible if the absence of HBV DNA is confirmed by HBV DNA polymerase chain reaction reflex testing performed in the central laboratory.

  11. Has chronic virus (HCV) (ie, positive HCV antibody [HCVAb] and HCV Ribonucleic Acid [RNA]).

    NOTE: Participants who are HCVAb-positive without evidence of HCV RNA may be considered eligible (spontaneous viral clearance or previously treated and cured [defined as no evidence of HCV RNA at least 12 weeks before baseline]).

  12. Has any identified congenital or acquired immunodeficiency (e.g. common variable immunodeficiency, infection, organ transplantation).
  13. Has positive stool studies for ova and/or parasites or stool culture at screening visit.
  14. Has positive Clostridium difficile stool test at screening visit.

    General Exclusion Criteria:

  15. Is taking, has taken, or is required to take any excluded medications.
  16. Has active cerebral/meningeal disease, signs/symptoms, or history of progressive multifocal leukoencephalopathy (PML) or any other major neurological disorders, including stroke, multiple sclerosis, brain tumor, or neurodegenerative disease.
  17. Has evidence of dysplasia or history of other than a successfully treated nonmetastatic cutaneous squamous cell or basal cell carcinoma or localized carcinoma in situ of the cervix.
  18. Has any unstable or uncontrolled cardiovascular, pulmonary, hepatic, renal, GI, genitourinary, hematologic, coagulation, immunological, endocrine/metabolic, neurologic, or other medical disorder that, in the opinion of the investigator, would confound the study results or compromise participant safety.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

  16. EuroQol- 5 Dimension for Youth (EQ-5D-Y) Index Scores and Visual Analogue Scale (VAS) at Week 14

    The EQ-5D-Y (Proxy Version 1.0) is composed of two sections. The first section contains one question for each of the five dimensions: mobility, looking after myself, doing usual activities, having pain or discomfort, and feeling worried, sad, or unhappy. Participants select from three response levels (no problems, some problems, a lot of problems) for each dimension. A health state profile score can be calculated from the responses on these five dimensions. The index score ranges from 0 (0 indicating a health state equivalent to death) to 1 (indicating full health). Higher scores demonstrate higher health utility. The second section includes a VAS (EuroQol \[EQ\] VAS). The scale is scored from 0 (the worst) to 100 (the best imaginable health). The reference to a high score indicates a better outcome of quality of life.

The second section includes a VAS (EQ VAS). The scale is scored from 0 (the worst) to 100 (the best imaginable health). The reference to a high score indicates a better outcome of quality of life.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 3, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
