Description
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.
- 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.
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.
Specific exclusions;
- HIV
- Hepatitis B or C
- Abnormal CBC at screening
i. Platelets <50 kg/uL or greater than 1.5 million kg/uL ii. WBC <50 x kg/uL iii. Hbg <7.0 g/dL d. Abnormal AST or ALT at screening(defined as >/= 2x ULN)
- 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

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Mesenchymal stem cells
Direct injection of allogeneic bone marrow derived mesenchymal stem cells at a dose of 75 million cells into the ileal pouch fistula(s) at baseline with a possible repeat injection at 3 months if not completely healed from the first injection.
|
Allogeneic bone marrow derived mesenchymal stem cells
|
Placebo Comparator: Placebo
Direct injection of normal saline.
If not completely healed after 6 months, participants will then cross over to the treatment group to receive a direct injection of allogeneic bone marrow derived mesenchymal stem cells at a dose of 75 million cells into ileal pouch fistula(s).

Treatment related adverse events
Time Frame: Month 6

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Complete clinical healing
Time Frame: Month 6, Month 12
|
Number of participants with complete clinical healing post-injection of 75 million allogeneic bone marrow derived MSC's for the treatment of medically refractory pouch fistulizing disease in the setting of Crohn's disease of the pouch. Complete Healing is defined as: Radiographic Healing: MRI with an absence of a fluid collection >2 cm in 3 of 3 dimensions, lack of edema, inflammation or sign of active inflammatory response. A remnant scar of a fistula tract may remain Clinical Healing: 100% cessation of drainage on both clinical exam with deep palpation and per patient report and epithelization of the external fistula opening |
Month 6, Month 12
|
Partial healing
Time Frame: Month 6, Month 12
|
Number of participants with partial clinical healing,post-injection of 75 million allogeneic bone marrow derived MSC's for the treatment of medically refractory pouch fistulizing disease in the setting of Crohn's disease Partial Healing is defined as: Radiographic Healing: MRI with an absence of a fluid collection >2 cm in 2 of 3 dimensions, lack of edema, inflammation or sign of active inflammatory response. A remnant scar of a fistula tract may remain Clinical healing: Greater than or equal to 50 % cessation of drainage on both clinical exam with deep palpation and per patient report and epithelization of the external fistula opening |
Month 6, Month 12
|
Lack of response
Time Frame: Month 6, Month 12
|
Number of participants with lack of response post-injection of 75 million allogeneic bone marrow derived MSC's for the treatment of medically refractory pouch fistulizing disease in the setting of Crohn's disease Lack of Response is defined as: Radiographic and Clinical healing which does not meet the threshold for Partial Healing |
Month 6, Month 12
|
Worsening disease
Time Frame: Month 6, Month 12
|
Number of participants with worsening disease-injection of 75 million allogeneic bone marrow derived MSC's for the treatment of medically refractory pouch fistulizing disease in the setting of Crohn's disease Worsening Disease is defined as: Radiographic: MRI with a fluid collection >2 cm in 2 of 3 dimensions, edema, inflammation or sign of active inflammatory response. An increased number of tracts may be seen, or increased branching from the primary tract, Clinical: Increased drainage per patient report and on clinical exam |
