Jazz Pharmaceuticals Announces First Patient Enrolled in Phase 3 Clinical Trial Evaluating Defibrotide for the Potential Prevention of VOD in High Risk Patients
"The initiation of this trial is another step forward in Jazz's development program for defibrotide as a treatment option for patients who are at high risk or very high risk of developing this life-threatening condition," said
The Phase 3 trial is a randomized, open-label, multi-center trial with an adaptive design comparing the efficacy of defibrotide vs. BSC in the prevention of hepatic VOD. The trial is expected to enroll approximately 400 adult and pediatric patients undergoing HSCT who are at high risk or very high risk of developing VOD. High (or very high) risk patients are identified due to the clinical regimen required to prepare them for HSCT, as well as their prior medical history and concomitant disease. The adaptive design allows for an interim analysis with pre-defined stopping points for early success or failure as well as the option to increase enrollment if needed to preserve the statistical power of the trial.
For patients randomized to receive defibrotide prophylaxis, defibrotide will be administered starting on the day before the first day of the conditioning regimen for a recommended minimum of 21 days and ending no later than Day +30 post HSCT. The primary endpoint is VOD-free survival at Day +30 post-HSCT. Additional information about the trial, including eligibility criteria and a list of clinical trial sites can be found at: www.clinicaltrials.gov (ClinicalTrials.gov Identifier: NCT02851407).

About VOD
HSCT is an aggressive, potentially curative procedure to treat patients with malignant and non-cancerous hematologic disorders such as leukemia, lymphoma and aplastic anemia, and congenital immunodeficiency and autoimmune disorders.2 VOD is a rare complication of HSCT, which occurs in approximately 9-14% of HSCT patients.3,4 Hepatic VOD, also known as SOS, is an early and life-threatening complication affecting the sinusoidal endothelial cells of the liver, which can typically occur within the first 21 days following HSCT.4,5 Hepatic VOD progresses to multi-organ dysfunction in approximately 30-50% of cases.5 VOD with multi-organ dysfunction (MOD) is associated with an overall mortality (death) rate of 84%.3 MOD is characterized by the presence of renal or pulmonary dysfunction.6,7 VOD is often characterized by sudden weight gain, hepatomegaly (abnormally enlarged liver), and elevated bilirubin.6,7
