Defibrotide in Treating Patients With Liver Damage Following Peripheral Stem Cell Transplantation

Phase 2
Completed
Conditions
Veno-occlusive Disease
Interventions
Registration Number
NCT00003966
Lead Sponsor
Dana-Farber Cancer Institute
Brief Summary

RATIONALE: Giving defibrotide may be an effective treatment for liver damage that may result following peripheral stem cell transplantation.

PURPOSE: This randomized phase II trial is studying defibrotide to see how well it works in treating patients with severe liver disease after undergoing peripheral stem cell transplantation.

Detailed Description

OBJECTIVES:

* Determine complete response rate in post-hematopoietic stem cell transplant patients with severe veno-occlusive disease of the liver treated with defibrotide.

* Determine the minimal effective dose of this drug in these patients.

* Assess toxicity and adverse side effects of this drug in these patients.

OUTLINE: This is a randomized, multicenter study. All patients initially receive the same dose of defibrotide IV over 2 hours every 6 hours on day 1. On day 2, patients are randomized to 1 of 2 doses of defibrotide.

* Arm I: On days 2-14, patients receive a lower dose of defibrotide IV over 2 hours every 6 hours.

* Arm II: On days 2-14, patients receive a higher dose of defibrotide IV over 2 hours every 6 hours.

In both arms, courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 140 patients (70 per treatment arm) will be accrued for this study.
