Donor Cytomegalovirus-Specific Cytotoxic T-Lymphocytes in Treating Patients With a Persistent Cytomegalovirus Infection

PRIMARY OBJECTIVE: I. To assess the efficacy, feasibility and safety of administering most closely human leukocyte antigen (HLA)-matched cytomegalovirus (CMV) specific cytotoxic T-lymphocytes (HMC-CTLs) generated by "gamma-catch" to mediate antiviral activity in hematopoietic stem cell transplantation (HSCT) recipients with CMV infections. SECONDARY OBJECTIVE: I. To assess the persistency of the administered HMC-CTLs generated by "gamma-catch" and their contribution immune reconstitution. OUTLINE: Patients receive allogeneic cytomegalovirus-specific cytotoxic T-lymphocytes intravenously (IV). Patients with partial response, stable disease, or progressive disease may receive an additional dose of allogeneic cytomegalovirus-specific cytotoxic T-lymphocytes at a minimum of 2 weeks from the first infusion. After completion of study treatment, patients are followed up periodically for 12 months.
