  Purpose
This comparative, multicentre, randomised clinical trial is designed with two parallel groups that will follow a treatment either with an autologous implant of ASCs (Adipose Derived Stem Cells) and fibrin glue (tissue adhesive material) or with fibrin glue alone for the non-surgical treatment of complex perianal fistula.

Condition Intervention Phase
Anal Fistula Procedure: Non-surgical autologous implant of ASCs Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Clinical Trial, Multicentre, Randomised and Comparative, to Evaluate the Efficacy and Safety of a New Therapy With Autologous Stem Cells Derived From Lipoaspirates for the Non-Surgical Treatment of Complex Perianal Fistula

Further study details as provided by Cellerix:

Primary Outcome Measures:
  • Complete closure at week 8 (defined as no suppuration from the external orifice and re-epithelization)

Secondary Outcome Measures:
  • No fistula recurrence after 1 year follow-up

Estimated Enrollment: 50
Study Start Date: October 2004
Estimated Study Completion Date: July 2006
Detailed Description:
Comparative, multicentre, randomised clinical trial, designed with two parallel groups that will follow a treatment either with an autologous implant of ASCs (Adipose Derived Stem Cells) and fibrin glue (tissue adhesive material) or with fibrin glue alone for the NON-SURGICAL treatment of complex perianal fistula. The closure/healing of the fistula will be evaluated periodically, and it will be considered completely closed if there is no suppuration from the external orifice and re-epithelialisation can be observed at 8 weeks after the administration of the randomised therapy.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients of both sexes older than 18 years of age.
  • Patients with a complex perianal fistula pathology which we define as the subjects that fulfil some of the following conditions:

    • No palpation of the fistula tract beneath the perianal skin.
    • A tract that is parallel to the rectum on exploration with a stylet.
    • Associated faecal incontinence.
    • Risk factors of anal incontinence.
    • At least one previous operation for a fistulous disorder.
    • Suprasphincteric trajectories
    • Rectovaginal fistula
    • Prior diagnosis of Crohn’s disease.
  • Patients from whom written informed consent has been obtained for them to participate in the study prior to performing any procedure described in the study.
  • Patients that have already been subjected to a colonoscopy within a period of up to 6 months prior to the study.

Exclusion Criteria:

  • Patients that are extremely thin who should not be subjected to liposuction.
  • Known allergy to local anaesthetics or to bovine proteins
  • History of neoplasia in the past 5 years.
  • Patients with a diagnosis of active Tuberculosis at the moment of inclusion.
  • Patients with prior positive markers for any of the following pathogens: Hepatitis B and C, HIV-1 or HIV-2.
  • Any other medical condition that in the judgement of the investigator could interfere with their optimal participation in the study or produce a significant risk to the patient.
  • Patients that have participated in another study in the 30 days prior to this one or that have planned to participate simultaneously in another study.
  • Patients that have not given their informed consent to participate in this study.
  • Psychiatric disorder or other factors that in the judgement of the investigator could complicate the participation of the patient in the study.
  • Breast feeding, gestation or intention to become pregnant up to 6 months after finalising their participation in the study, or that are not using adequate methods of contraception during the same period.
