To evaluate the role of allogeneic mesenchymal stem cells for treatment of perianal
fistulizing Crohn disease.
Twenty (20) Crohn's disease patients with complex or multiple perianal or rectovaginal
fistulas will be included and will be scheduled to undergo peri-fistula injections after
meeting all inclusion/exclusion criteria's at baseline.
Following the Pilot Phase of four (4) subjects, sixteen (16) subjects are scheduled to

Subjects with Fistulizing Crohn´s disease with complex perianal fistula, multiple perianal fistulas, or rectovaginal fistula(s). The complex perianal fistula is defined as a trans-sphincteric, supra-sphincteric or an extra-sphincteric tract. Patients with multiple fistulas, "horseshoe" fistula," or any fistula with fecal incontinence as a result of the Crohn's disease itself or because of previous anal fistula surgery that cannot have more surgery are also eligible. 4. If drainage of abscess is needed, it should be done 2 or more weeks prior to onset of therapy. 5. Have had Crohn's Disease (CD) diagnosed at least 6 months prior to enrollment based on clinical, endoscopic, anatomic/pathologic and/or radiologic criteria. 6. Have a CDAI score <350. 7. During the course of the subject's Crohn's disease (CD), subject must have received anti-Tumor Necrosis Factor (TNF) agents or immunomodulators which did not heal the CD fistulas. If anti-TNFs or immunomodulators are contraindicated or led to adverse events, patients must have failed conservative therapy with antibiotics, or setons, or surgical intervention. 8. Subject who are currently receiving anti-TNFs, antibiotics, 5-aminosalicylic acid, azathioprine, 6-mercaptopurine, methotrexate, prednisone, or any similar drugs at the time of enrollment as long as the following criteria are met: 1. The patient must have been on the anti-TNF for at least 4 months 2. The dose of 5-aminosalicylic acid (5-ASA) must have been stable for at least 4 weeks prior to enrollment. 3. The dose of steroids must have been stable for at least 2 weeks prior to enrollment. 4. The dose of antibiotics must have been stable for at least 2 weeks prior to enrollment. 5. The dose of immunomodulators (for example, azathioprine, 6-mercaptopurine, or methotrexate) must have been stable for at least 8 weeks prior to enrollment and the subject on therapy for at least three months prior to enrollment 9. Patient is, in the investigator's opinion, willing and able to comply with the protocol requirements Exclusion Criteria: In order to participate in this study, a patient Must Not: 1. Have a known, serious radiographic contrast allergy (gadolinium in particular) 2. Have a hematologic abnormality as evidenced by hematocrit < 25%, white blood cell < 2,500/ul or platelet values < 100,000/ul without another explanation. 3. Have liver dysfunction, as evidenced by enzymes (AST and ALT) greater than three times the Upper limit normal. 4. Have a coagulopathy (International Normalized ratio (INR) > 1.3) not due to a reversible cause (i.e., Coumadin). Patients on Coumadin will be withdrawn 5 days before the procedure and confirmed to have an INR < 1.3. Patients who cannot be withdrawn from Coumadin will be excluded from enrollment. 5. Bone marrow dysfunction, as evidenced by a 20% or more deviation from normal hematocrit, white blood cell count or platelet values without another explanation. 6. Be an organ transplant recipient. 7. Clinical history of malignancy within 5 years (i.e., patients with prior malignancy must be disease free for 5 years), except curatively-treated basal cell carcinoma, squamous cell carcinoma, or cervical carcinoma. 8. Non-cardiac condition that limits lifespan to < 1 year. 9. Patients with a highly active luminal CD, i.e., if they meet any of the following criteria: - Presence of severe proctitis (prominent friability, spontaneous bleeding, multiple erosions, deep ulcers) or very active luminal disease that requires immediate treatment, revealed by colonoscopy. 10. Have anal dysplasia 11. Patients that have received radiation to the pelvic/perianal area. 12. Presence of abscess or other collections not drained (revealed by baseline radiologic study). 13. Presence of setons unless they are removed before treatment beginning. 14. Rectal and/ or anal stenosis that cannot be adequately evaluated for dysplasia by Examination under anesthesia or endoscopy. 15. Need surgery in the perianal region for reasons other than fistulas at inclusion or within 16 weeks after treatment administration. 16. Had a stable dose of an anti-TNF agent within the past 8 weeks before the cell treatment administration. 17. Taking tacrolimus or cyclosporine and not on a stable maintenance dose for 2 weeks before the start of scheduled interventions. 18. Have a history of alcohol or other addictive substances abuse within 6 months before inclusion. 19. Severe uncontrolled diseases (chronic renal failure, cardiovascular, pulmonary or any systemic disease). 20. Any type of medical or psychiatric disease which are considered as exclusion criteria, in the investigator's opinion. 21. Subjects with congenital or acquired immunodeficiency. 22. Positive serology for Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV) or Hepatitis C Virus (HCV), Human papillomavirus (HPV) or Herpes Virus. 23. Had major surgery or serious traumatism within 6 weeks of enrollment. 24. Impossibility of doing an radiological exploration (reaction to contrast material, pacemakers, claustrophobia, etc.) 25. Have hypersensitivity to dimethyl sulfoxide (DMSO) 26. Be currently participating (or participated within the previous 30 days) in an investigational therapeutic or device trial. 27. Be a female who is pregnant, nursing, or of childbearing potential while not practicing effective contraceptive methods. Female patients must undergo a blood or urine pregnancy test at screening and within 36 hours prior to injection. |

Primary | Evaluation of treatment emergent adverse events from the bone marrow-derived allogeneic mesenchymal stem cells implant | Evaluation of treatment emergent adverse events based on viability, safety and tolerance of the bone marrow-derived allogeneic mesenchymal stem cells implant (MSCs) in fistulizing Crohn's Disease patients, defined as: Treatment emergent adverse event (AE) rates, infections, hospitalizations or surgical interventions. Physical examination Vital signs Laboratory tests (biochemistry, hematology, urinalysis) |
At each intervention and 7, 10, and 16 months after last intervention | |
Secondary | Clinically: to assess changes in the Crohn's Disease Activity Index (CDAI), the Perianal Disease Activity Index (PDAI). | To monitor the number of draining fistulas, fistula healing efficiency, relapse rate among patients who achieved treatment success and amount local inflammation: Complete closure will be defined as absence of discharge and absence of collections of =2 cm directly related to the treated fistulas tracts as assessed by perianal examination. Partial closure will be defined as a reduction in >50% draining fistulas or no discharge on finger compression. | At each intervention and 7, 10, and 16 months after last intervention | |
Secondary | Endoscopic assessment of rectum using a limited simplified endoscopic activity score for Crohn's disease (SES-CD) to evaluate extent and severity of ulcers. | Endoscopic ultrasound and Examination under anesthesia to evaluate baseline fistula state and during each intervention to assess tract closure and abscesses. Remission will be defined as healing of rectal ulcers and/or closure of fistula tracts by endoscopic ultrasonography. | At each intervention and 7, 10, and 16 months after last intervention | |
Secondary | Radiologic assessment using MRI | to examine number of tracts, inflammation in tracts, and extent of fibrosis or regenerative tissue via MRI assessment. Radiologic remission will be defined as substitution of tracts with fibrosis or regenerative tissue. | Baseline, Month 4, and 16 months only if fistula closure has not been achieved at month 4 | |
Secondary | Evaluate symptomatic patients. | Endoscopic ultrasound and MRI will be used to evaluate symptomatic patients. | Month 4 and Month 16 | |
Secondary | Evaluate the effect of local treatment with allogeneic bmMSCs using the short Inflammatory Bowel Disease Questionnaire (sIBDQ) | To evaluate the effect of local treatment with allogeneic bmMSCs on the quality of life of patients with fistulizing CD using the short Inflammatory Bowel Disease Questionnaire (sIBDQ) | At each intervention and 7, 10, and 16 months after last intervention | |
Secondary | Evaluate the effect of local treatment with allogeneic bmMSCs using the Short Form (SF)-36 score | To evaluate the effect of local treatment with allogeneic bmMSCs on the quality of life of patients with fistulizing CD using the Short Form (SF)-36 score | At each intervention and 7, 10, and 16 months after last intervention | |
Secondary | C-reactive protein (CRP) | To summarize the changes from baseline compared to 12 weeks in serum C-reactive protein | At each intervention and 7, 10, and 16 months after last intervention | |
Secondary | Major Adverse Events | • Incidence of the Major Adverse Events endpoint, defined as the composite incidence of (1) death (2) hospitalization for worsening fistulizing disease (3) or infection caused by the intervention. | At each intervention and 7, 10, and 16 months after last intervention |
