NCT03000296

Brief Summary

This study evaluates the safety and clinical benefits of a therapeutic approach using the cyclophosphamide (Cy) + thymoglobulin® (ATG) + granulocyte colony-stimulating factor (G-CSF) conditioning regimen followed by autologous hematopoietic stem cell transplantation (HSCT) rescue in the treatment of refractory Crohn's disease. Adverse events, and clinical and endoscopic conditions will be assessed at different short and long-term time points.

Outcome Measures

Primary Outcomes (1)

  • Safety of unselected autologous HSCT in refractory Crohn´s disease patients

    HHSCT safety will be analyzed by laboratory tests and treatment-related adverse events. Safety will be evaluated by treatment-related adverse events. All adverse events will be recorded in a standardized way and their relationship to the study protocol will be assessed at different short- and long-term time points.

    12 months

Secondary Outcomes (8)

  • Crohn´s Disease Activity Index (CDAI)

    12 months

  • CRAIG Crohn´s Severity Score (CSS)

    12 months

  • Inflammatory Bowel Disease Questionnaire (IBDQ)

    24 months

  • Short Form-36 Health Survey (SF-36)

    24 months

  • Simple Endoscopic Activity Score (SES)

    24 months

  • +3 more secondary outcomes

Study Arms (1)

Hematopoietic Stem Cell Transplantation

EXPERIMENTAL

High doses immunosuppression Cyclophosphamide (200 mg/kg total dose for four days) and rabbit antithymocyte globulin (6.5 mg/kg total dose for four days) followed by unselected autologous hematopoietic stem cell transplantation rescue.

Procedure: Autologous Hematopoietic Stem Cell Transplantation

Interventions

Hematopoietic stem cell transplantation Lymphoablation followed by hematopoietic stem cell transplantation to rescue the immune system.

Eligibility Criteria

Age14 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Age between 14 and 50 years (patients aged 50 - 70 can participate at the principal investigators discretion).
  • Confirmed diagnosis of active Crohn's disease:
  • Diagnosis of Crohn's disease based on typical radiological findingsand or typical histology at least 6 months prior to screening.
  • Active disease at the time of registration to the trial, defined as
  • \*Crohn's Disease Activity Index (CDAI) \> 150, and ii) Two of the following:
  • Harvey Bradshaw Index \> 4
  • Endoscopic evidence of active disease confirmed by histology
  • Clear evidence of active small bowel Crohn's disease on computed tomography (CT) or magnetic resonance (MR) enterography.
  • Unsatisfactory course despite immunosuppressive agents (usually azathioprine, methotrexate and two biologic agents (normally infliximab, adalimumab and/or certolizumab) in addition to corticosteroids. Patients should have relapsing and refractory disease despite thiopurines, methotrexate and/or infliximab/adalimumab/certolizumab maintenance therapy or clear demonstration of intolerance / toxicity to these drugs.
  • Current problems unsuitable for surgery or patient at risk for developing short bowel syndrome.
  • Informed consent:
  • Prepared to undergo additional study procedures as per trial schedule
  • Patient has undergone intensive counseling about risks

You may not qualify if:

  • Pregnancy or unwillingness to use adequate contraception during the study, in women of childbearing age. Unwillingness of using appropriate contraceptive measures in males.
  • Concomitant severe disease
  • renal: creatinine clearance \< 30 mL/min (measured or estimated)
  • cardiac: clinical evidence of refractory congestive heart failure; left ventricular ejection fraction \< 40% by multigated radionuclide angiography (MUGA) or cardiac echo; chronic atrial fibrillation necessitating oral anticoagulation; uncontrolled ventricular arrhythmia; pericardial effusion with hemodynamic consequences as evaluated by an experienced echo cardiographer.
  • pulmonary: diffusion capacity \<40%
  • psychiatric disorders including active drug or alcohol abuse
  • concurrent or recent history of malignant disease (excluding non-melanoma skin cancer)
  • uncontrolled hypertension, defined as resting systolic blood pressure ≥ 140 and/or resting diastolic pressure ≥ 90 despite at least 2 anti-hypertensive agents.
  • uncontrolled acute or chronic infection with HIV, Human T-lymphotropic virus (HTLV-1 or 2), hepatitis viruses or any other infection the investigators consider a contraindication to participation.
  • other chronic disease causing significant organ failure.

The main objective is to observe the safety and clinical benefit of autologous HSCT therapy in refractory patients with Crohn's disease. Evaluation during transplant period and 1, 3, 6, 12 and 24 months post-transplant. Safety be evaluated by the amount of treatment-related adverse events. Record adverse events in a standardized way. Secondary outcome measures will be disease remission: 1, 3, 6, 12 and 24 months post-transplant both clinical and endoscopic remission. The percentage of patients in sustained disease remission at 1, 3, 6, 12 and 24 months post HSCT will be determined. Sustained disease remission is defined as a CDAI \< 150; HBI \<4, CCSI\< 16, without the use of corticosteroids, immunosuppressant or biologic agents. Mucosal healing will be assessed during ileocolonoscopy at 6, 12, and 24 months following HSCT using SES, CDEIS and Rutgeerts endoscopy index. Heath Quality life, Short Form 36 and IBDQ at 1 3 6 12 and 24 months post-Transplant.
