Study of Mesenchymal Stem Cells for the Treatment of Ileal Pouch Fistula's in Participants With Crohn's Disease

Stopped early · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Ileal Pouch, Crohn Disease

In brief

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.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

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.
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
Ability to comply with protocol.

You may not qualify if…

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.

History of cancer including melanoma (with the exception of localized skin cancers) within one year of screening
History of colorectal cancer within 5 years
Investigational drug within thirty (30) days of baseline
Pregnant or breast feeding or trying to become pregnant
Branching fistula tract that has > 2 internal openings or 3 external openings,
Subjects with greater than 3 blind/branching tracts are excluded
Fistula tracts on the left and/or right side are allowed
Allergic to local anesthetics
Unwilling to agree to use acceptable contraception methods during participation in study
Subjects with a non-abscessed chronic cavity will not be included in enrollment
