Vaccine Therapy For Patients Being Considered For Organ Transplant Who Are at Risk For PTLD

Lymphoproliferative Disorder Clinical Trial

Official title: Vaccination of Patients at High Risk for Post-Transplant Lymphoproliferative Disorder With a Photochemically Inactivated EBV-Infected B-Cell Vaccine

Status Terminated

Clinical Trial Summary

RATIONALE: Vaccines made from a person's white blood cells may help the body build an effective immune response. PURPOSE: This phase I trial is studying the side effects of vaccine therapy in treating patients who are being considered for solid organ transplant who are at risk for post-transplant lymphoproliferative disorder.

Clinical Trial Description

OBJECTIVES: Primary - Determine the efficacy of photochemically-treated autologous Epstein-Barr virus (EBV)-transformed B-lymphoblastoid cell vaccine in generating an EBV-specific T-cell and antibody response in EBV-negative patients or in boosting the response in EBV-positive patients who are being considered for a solid organ transplant and are at high risk for post-transplant lymphoproliferative disorder. - Determine adverse events associated with this vaccine in these patients. - Determine the ability of the vaccine to protect from EBV primary infection in EBV-seronegative patients during the time course of the study. OUTLINE: This is a nonrandomized, pilot study. Patients are stratified according to Epstein-Barr virus (EBV) status (seropositive vs seronegative). Patients receive photochemically-treated autologous EBV-transformed B-lymphoblastoid cell vaccine intradermally once in weeks 0 and 4. After completion of study treatment, patients are followed periodically for up to 5 years. PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study. ;
