Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42585   clinical trials with a EudraCT protocol, of which   7011   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.1.2Term Anal fistula
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the study is to evaluate the efficacy of intralesional administration of eASCs (CX-401) when added to standard surgical care and drainage for the treatment of complex perianal fistulas in patients with CD.
    E.2.2Secondary objectives of the trial
    •To evaluate the safety of intralesional administration of eASC’s (CX-401) when given at baseline with a possible repeat dose at Week 12, and a follow-up period of 12 weeks.
    • To evaluate the effect of intrafistular administration of eASC’s (CX-401) on the incidence of complications of complex fistulas in patients with CD (such as abscesses or fluid collections) using MRI.
    • To compare the use of eASC’s (CX-401) with placebo with regard to the fistular relapse rate.
    • To obtain data regarding prevention of invasive surgical procedures and use of additional therapies.
    • To obtain QoL data.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    "Inflammation substudy (Biomarker Evaluation)" (only applicable at selected sites in Spain)

    1.- To determine both the frequency of the population of regulatory T cells (Treg) and the ratio Treg/Th17 in the blood of patients from FATT-2 study. This research may potentially link the frequency of Tregs in the blood of patients as an in vivo maker for Ontaril efficiency.
    2.- To investigate the levels of pro-inflammatory (Th1) cytokines and compare them to the levels of anti-inflammatory (Th2) cytokines. Analysis is designed to correlate the healing of the fistula induced by the ASC treatment with cytokine levels.
    E.3Principal inclusion criteria
    A patient can be included in the study if he/she meets ALL the criteria listed below:
    1. Signed informed consent.
    2. Patients with CD diagnosed at least 12 months earlier in accordance with accepted clinical,
    endoscopic, anatomical/topographical and/or radiologic criteria.
    France and Italy only:Patients with CD diagnosed at least 12 months earlier in accordance with accepted clinical, endoscopic, anatomical/topographical and/or radiological criteria, unresponsive (treatment failure and/or intolerance and/or contraindication) to conventional treatment, including anti-TNF. Treatment failure means persistence or recurrence of fistula-related discharge despite correctly conducted induction treatment with anti-TNF antibodies with at least 3 infusions/injections. It is, however, possible to authorize inclusion of patients who do not tolerate anti-TNF antibodies (allergy) and, in consequence, have not received a complete course of anti-TNF antibody treatment. Patients to whom treatment with anti-TNF agent is contraindicated, may also be included if they fulfill other eligibility criteria.
    3. Presence of complex perianal fistula with up to 3 external openings, assessed by MRI. The blinded fistulae branches visible though MRI are not considered fistula tracts but branches of the main tract. A complex perianal fistula is defined as a fistula that meets one or more of the following criteria:
    - High fistulas (high inter-sphincteric, high trans-sphincteric, extra-sphincteric or
    - Presence of 3 or fewer external openings associated to a complex perianal fistula.
    4. Non-active or mildly active luminal CD defined by a CDAI ≤220.
    5. Patients of either sex aged 18 years or older. Good general state of health according to clinical history and a physical examination.
    6. Women of a childbearing age with negative serum or urine pregnancy test (sensitive to 25 IU human chorionic gonadotropin [hCG]). Both men and women should use appropriate birth control methods defined by the investigator.
    E.4Principal exclusion criteria
    A patient cannot be included in the study if he/she meets ANY of the criteria listed below
    1. Presence of severe proctitis (prominent friability, spontaneous bleeding, multiple erosions, deep ulcers) or dominant active Crohns disease requiring immediate therapy, assessed by rectosigmoidoscopy
    2. CDAI >220.
    3. Presence of an abscess or collections >2 cm, unless a complete surgical debridement of the area has been performed, including drainage of the collection(s) and an MRI scan confirms absence of (residual) abscess before randomization.
    4. Presence of setons. If present at screening they should be removed prior to treatment administration.
    5. Presence of >3 external openings.
    6. Rectal and/or anal stenosis.
    7. Treatment with infliximab or any other anti-TNF agent in the 8 weeks before the cell treatment administration.
    8. Patients having received adalimumab in the 4 weeks before the cell treatment
    9. Treatment with tracrolimus or cyclosporine in the 4 weeks before the cell treatment administration.
    10. HIV, HBV, HCV or treponema infection.
    11. Persistent chronic bacterial infections of temporary nature as well as local infections unless succesfully treated prior liposuction, such as syphilis, brucellosis, typhus, melioidosis, qfever, meningitis, or other.
    12. Renal impairment defined by creatinine clearance below 60 ml/min calculated using Cockcroft-Gault formula (see appendix I) or the following laboratory ranges:
    Total bilirubin ≥ 1.5 x upper limit of normal (ULN) AST and ALT ≥ 2.5 X ULN
    Serum creatinine ≥ 1.5 ULN
    13. Known history of abuse of alcohol or other addictive substances in the 6 months prior to inclusion.
    14. Malignant tumor or patients with a prior history of malignant tumors.
    15. Current or recent history of abnormal, severe, progressive, uncontrolled liver function, anemia, hepatic, hematological, gastrointestinal (except CD), endocrine, pulmonary, cardiac, neurological, psychiatric ,or cerebral disease.
    16. Congenital or acquired immunodeficiencies.
    17. Known allergies or hypersensivity to antibiotics including but not limited to penicillin, streptomycin, gentamicin, aminoglycosides; HSA; DMEM; materials of bovin origin; local anesthetics or gadolinium (MRI contrast).
    18. Contraindication to MRI scan, (e.g., due to the presence of pacemakers, hip replacements or severe claustrophobia).
    19. Liposuction with extraction of at least 100 cm3 of fat from the abdominal wall is technically unfeasible or the patient does not consent to the procedure.
    20. Major surgery or severe trauma within the previous 6 months.
    21. Pregnant or breastfeeding women.
    22. Patients who do not wish to or cannot comply with study procedures.
    23. Patients currently receiving, or having received within 3 months prior to enrolment into this clinical study, any investigational drug.
    24. Patients unlikely to comply with study procedures.
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is the percentage of anti-TNF exposed patients with complete closure of their treated complex perianal fistula at Week 24. Complete closure of the fistula is defined as:
    • Absence of drainage/suppuration of the fistula through the external orifice, either spontaneously or when applying pressure, and
    • Complete re-epithelization of the external orifice (clinical evaluation), and
    • Absence of fluid collections >2 cm directly related to the treated fistula tract, as measured by MRI, in the longest diameter.
    Clinically, complete closure must be confirmed at both, the Week 24 and the Week 26 visit.
