Exploratory Study of EBV-TCR-T Cell Injection for EBV DNAemia After Allogeneic Hematopoietic Stem Cell Transplantation
Summary
Epstein-Barr virus (EBV) DNAemia is a common and potentially serious complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and may progress to EBV-associated lymphoproliferative disorders. Current treatment options are limited, and effective immune-based therapies are still needed. This is an investigator-initiated, exploratory, open-label, single-arm clinical study designed to evaluate the safety, tolerability, and preliminary efficacy of EBV-specific T cell receptor-engineered T cells (EBV-TCR-T cell injection) in patients with EBV DNAemia after allo-HSCT. Eligible participants will receive intravenous infusions of EBV-TCR-T cells at escalating dose levels. Safety outcomes, EBV-DNA clearance, and preliminary efficacy will be assessed, along with pharmacokinetic and pharmacodynamic characteristics of the infused cells.
