Brief 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.
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 biopsy) 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 contraindication). 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.

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