Phase III Randomized Study of Cyclophosphamide With or Without Antithymocyte Globulin Before Bone Marrow Transplantation in Patients With Aplastic Anemia

Phase 3

Completed

• Conditions: Aplastic Anemia
• Interventions: Drug: Anti-thymocyte globulin; Drug: Cyclophosphamide; Procedure: Bone marrow transplantation

• Registration Number: NCT00004474
• Lead Sponsor: Roswell Park Cancer Institute

Brief Summary

OBJECTIVES:

I. Compare outcome, including graft failure, graft versus host disease, and survival of HLA-identical sibling bone marrow transplants for aplastic anemia using cyclophosphamide with or without antithymocyte globulin as a conditioning regimen.

Detailed Description

PROTOCOL OUTLINE: This is a randomized, multicenter study. Patients are randomized to receive cyclophosphamide IV over 60 minutes on days -5 to -2 with or without antithymocyte globulin IV over 4 hours.

All patients then receive bone marrow over 60-120 minutes on day 0, 36 hours after the last dose of cyclophosphamide.

Patients are followed at day 100, at 6 months, and at 1 year posttransplant.
