Plain-language summary
Restorative proctocolectomy with ileal pouch anal anastomosis (IPAA) is the procedure of choice for patients with ulcerative colitis, familial adenomatous polyposis, and select patients with Crohn's disease due to overall low patient morbidity and good quality of life. However, some patients can develop Crohn's disease of the pouch, a clinical diagnosis of Crohn's disease following IPAA. One of the manifestations of Crohn's disease of the pouch includes a fistula from the pouch that travels to the vagina or perianal area. These fistulas can be quite difficult to manage with medications and local surgical intervention, and, on occasion result in a reconstruction pouch but more often require a pouch excision with permanent end ileostomy. The purpose of this study is to evaluate the safety and efficacy of using allogeneic bone marrow derived mesenchymal stem cells to treat people who have a peri-pouch fistula related to a clinical diagnosis of Crohn's disease of the pouch.

Inclusion criteria
. Men and women 18-75 years of age who have undergone an ileal pouch anal anastomosis at least 6 months prior who have developed a clinical diagnosis of Crohn's disease of the pouch as determined by a combination of clinical symptoms, pouchoscopy with biopsy, enterography.
. Single and multi-tract (up to 2 internal and 3 external openings) fistula tract arising from the ileal pouch, ileal anal anastomosis, or anal canal distal to anastomosis that travels to the perianal skin, perineal body, or vagina. Patients with fistulas that arise from the pouch, anastomosis, or anal canal distal to the anastomosis will both be included in enrollment.
. Acceptable internal openings and tract locations for the fistula to arise from include the ileal pouch body, the pouch anal anastomosis, and the anal canal distal to the anastomosis.
. Acceptable external openings and tract locations for the fistula to arise from include the perianal skin, perineal body, and/or the vaginal wall.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Concurrent Crohn's related therapies with stable doses (\>2 months) corticosteroids, 5-ASA drugs, immunomodulators, anti-TNF therapy, anti-integrin and anti-interleukin are permitted.
. Have failed conventional medical therapies described above, defined as a lack of response to systemic immune suppression (e.g. azathioprine, methotrexate, 6-mercaptopurine) or biologic (e.g. anti-TNF, anti-integrin, anti-interleukin) therapies to treat fistulizing CD for at least 2 months
. Have no contraindications to MR evaluations: e.g. pacemaker or magnetically active metal fragments, claustrophobia
. Competent and able to provide written informed consent
Exclusion criteria
. Inability to give informed consent.
. Severe antibiotic refractory pouchitis
. Severe cuffitis refractory to antibiotics
. Change in medical management for CD in the previous 2 months or changes anticipated in the next 2 months
. Clinically significant medical conditions within the six months before administration of MSCs: e.g. myocardial infarction, active angina, congestive heart failure or other conditions that would, in the opinion of the investigators, compromise the safety of the subject.
