AlloGeneic Human Mesenchymal Stem Cells (hMSC) in PAtients With FistuLizing Crohn's Disease Via PErifistula iNjEctions (GALENE)

Study Purpose

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 undergo perianal injections and after meeting all inclusion/exclusion criteria's, will be evaluated at baseline.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All

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.

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 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 Patients on Coumadin will be withdrawn 5 days before the procedure and confirmed to have an INR 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 Patients who cannot be withdrawn from Coumadin will be excluded from enrollment. 5.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.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Twenty (20) subjects will be treated with 20 million (2 x 10^7) allogeneic MSC's total divided into 10 injections of 2 million cells/cm of tract in 0.5 ml volume (for total volume of 5 ml per visit) at 4 week intervals for a maximum of 4 treatment sessions based on the discretion of the endoscopist at the time of injection.. For patients with more than 6 fistula tracts, the largest of the tracts will be injected. The first four

  • (4) subjects that receive their initial injections will not be treated less than 5 days apart.
As stated in the above response, these first four
  • (4) patients will have an initial safety follow up period of one month prior to proceeding with the treatment of further patients.
Follow up: Clinical (CDAI, PDAI, and perianal examination +/- under anesthesia), and endoscopic ultrasound will be performed at the time of each treatment. MRI evaluation will be performed at screening, 4 weeks after the fourth treatment (week 16) and at 16 months, if fistula closure has not been achieved. Clinical evaluation will be performed at months 1, 3, 6, 12. Endoscopic ultrasound and MRI will also be performed as needed for symptomatic patients if an abscess is suspected. Duration of Study participation: 17 Months (Follow-up visits will be at 4, 7, 10 and 16 Months post treatment. The Allo-hMSCs will be supplied from an allogeneic human mesenchymal stem cell source manufactured by the University of Miami.
