Rituximab (Rituxan) for the Prevention of EBV-LPD Epstein Barr Virus (EBV) Lymphoproliferative Disorder Post T Cell Depleted Unrelated and HLA Mis-matched Related HSCT

• Status: Completed
• Trial end date: 2008-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine if we can prevent Epstein Barr Virus lymphomas by the monthly administration of an (antibody) protein against B lymphocytes called Rituximab. Although this medicine has been approved by the Food and Drug Administration to treat patients with other types of lymphomas, and has been used to treat a small number of patients with EBV lymphomas and other types of B-cell leukemias, it has not been approved to try and prevent EBV-lymphomas. Use of Rituximab to try to prevent EBV-lymphomas is therefore experimental.
