Brief Summary:
The aim of this trial is to evaluate whether the prophylactic use of Defibrotide (DF) in pediatric patients (age less than 18 years) undergoing stem cell transplantation and who are at high risk of developing hepatic Veno-occlusive Disease (VOD) will have an impact on the incidence and severity of the disease. Patients will be randomly assigned to one of two treatment arms: Those allocated to the Prophylactic Arm will receive the study drug (Defibrotide) from the day of conditioning onwards. Patients allocated to the Control Arm will receive the study drug (Defibrotide) from the day that VOD is diagnosed.

Condition or disease Intervention/treatment Phase
Hepatic Veno-Occlusive Disease Drug: Defibrotide Phase 2 Phase 3

Detailed Description:

Comparison/control intervention and duration of the intervention:

Patients will be assigned randomly to either the Defibrotide (DF) prophylaxis arm or the control arm. Those allocated to the DF prophylaxis arm (DF 25 mg/kg/d iv in 4 doses) will begin treatment at day of conditioning and stop at day +30 after Stem Cell Transplantation (SCT) or upon discharge from inpatient care. There is no dose adjustment for a patient of the study arm who developed VOD, they continue with the 25mg/kg/d iv.

Patients allocated to the control arm receive no prophylactic measures and will start DF (25 mg/kg/d iv in 4 doses) beginning at day of diagnosis of Veno-occlusive Disease (VOD) according to modified Seattle criteria. Treatment will be stopped at complete resolution of symptoms. In both arms patients who developed VOD will continue DF until:

  • complete resolution of the ascites and
  • reversion of the hepatopedal flow (if present) and
  • normalization of the total and direct bilirubin

Arm Intervention/treatment
Experimental: Prophylaxis Arm Drug: Defibrotide
Defibrotide 25 mg/kg/d

Drug: Defibrotide
Defibrotide 25 mg/kg/d iv in 4 doses beginning at day of conditioning until day +30 or until discharge from inpatient care (with a minimum treatment of 14 days) if VOD does not occur.

Active Comparator: Control Arm Drug: Defibrotide

Primary Outcome Measures :
  1. The primary objective is to evaluate if prophylactic DF has an impact on the incidence of VOD [ Time Frame: Day + 30 post HSCT ]

Secondary Outcome Measures :
  1. Occurrence of Multi-System Organ Failure and Survival (all causes of mortality) [ Time Frame: day +100 post HSCT ]
