Defibrotide for the Treatment of Severe Hepatic Veno-Occlusive Disease in Hematopoetic Stem Cell Transplant Patients
This study is ongoing, but not recruiting participants.
Sponsors and Collaborators: Gentium SpA
FDA Office of Orphan Products Development
Information provided by: Gentium SpA
ClinicalTrials.gov Identifier: NCT00358501
  Purpose

The purpose of this study is to (1) demonstrate the efficacy and safety (toxicity) of 25 mg/kg/day of Defibrotide in patients with severe veno-occlusive disease (sVOD) and (2) evaluate serum and endothelial markers of VOD through the analysis of blood samples.


Condition Intervention Phase

Study Type: Interventional
Study Design: Treatment, Non-Randomized, Open Label, Historical Control, Single Group Assignment, Safety/Efficacy Study
Official Title: Defibrotide for the Treatment of Severe Hepatic Veno-Occlusive Disease in Hematopoetic Stem Cell Transplant Patients: A Historically-Controlled, Multi-Center Phase 3 Study to Determine Safety & Efficacy

Further study details as provided by Gentium SpA:

Primary Outcome Measures:
  • Complete Response at D+100 post stem cell transplant

Secondary Outcome Measures:
  • Survival at D+100 following stem cell transplant
  • Long-term (6 month) survival rate
  • Safety of the selected dose and schedule

Estimated Enrollment: 80
Study Start Date: July 2006
Detailed Description:

This is a historically-controlled, multicenter, open label Phase 3 study to determine the safety and efficacy of 25 mg/kg/day of Defibrotide (DF) for the treatment of severe VOD in hematopoietic SCT patients.

In this study, the term "severe VOD" is defined as those patients who meet the Baltimore diagnostic criteria for VOD (total bilirubin >/= 2.0 mg/dL plus two of the following: ascites, >/=5% weight gain and hepatomegaly), who also have MOF (i.e., pulmonary and/or renal dysfunction). This represents a group of patients in whom mortality at D+100 has been estimated to be >80%.

Comparisons: The primary parameter is Complete Response at 100 days following stem cell transplant, utilizing historical controls as a comparator. The historical control database will be generated through a retrospective medical chart review performed at participating centers; the survival outcome of patients who would otherwise have met eligiblity criteria for this trial will be compared to the survival observed in patients prospectively treated with defibrotide. Secondary parameters include survival rate at 100 days and 6 months post SCT, and special studies of endothelial and serum markers for VOD. This study will assess safety of the dose and schedule in this setting.

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Clinical diagnosis of VOD, defined by jaundice (bilirubin >/= 2 mg/dL) and at least 2 of the following clinical findings, by Day +21 post stem cell transplant: ascites; weight gain >/= 5% above baseline weight; hepatomegaly.
  • Severe VOD, defined as VOD with multi-organ failure, i.e., presence of one or both of the following, by Day +28 post stem cell transplant: renal or pulmonary dysfunction.
  • Provide voluntary written informed consent.

Exclusion Criteria:

  • Pre-existing (prior to SCT) cirrhosis
  • An alternative diagnosis for weight gain, ascites and jaundice
  • GVHD grade B or higher involving liver or gut or grade C or higher involving skin
  • Prior solid organ transplant
  • Dependent on dialysis prior to and/or at the time of SCT
  • Dependent on oxygen supplementation prior to SCT
  • Significant acute bleeding or hemodynamic instability
  • Requirement for the use of any medications that increase risk of hemorrhage will be excluded from the treatment group
