LMP1/BARF1/EBNA1-Specific Cytotoxic T-Lymphocytes with or without Cyclophosphamide and Fludarabine in Treating Participants with EBV-Positive Lymphoma

Trial Status: closed to accrual

This phase I trial studies the side effects and best dose of LMP1/BARF1/EBNA1-specific cytotoxic T-lymphocytes when given together with or without cyclophosphamide and fludarabine in treating participants with Epstein-Barr virus (EBV)-positive lymphoma. Immunotoxins, such as LMP1/BARF1/EBNA1-specific cytotoxic T-lymphocytes, are antibodies linked to a toxic substance and may help find certain cancer cells and kill them without harming normal cells. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving LMP1/BARF1/EBNA1-specific cytotoxic T-lymphocytes, cyclophosphamide, and fludarabine together may work better in treating participants with EBV-positive lymphoma.
