EBV Associated Lymphoid Neoplasms

Epstein-Barr virus (EBV) is a double-stranded DNA virus belonging to the Gammaherpesvirinae subfamily of Herpesviridae. It primarily infects B cells and pharyngeal epithelial cells, and can also infect NK cells and T cells. EBV is closely associated with a variety of hematological malignancies, including EBV-positive diffuse large B-cell lymphoma (EBV+DLBCL), NK/T-cell lymphoma (NKTCL), Hodgkin lymphoma (HL), Burkitt lymphoma (BL), EBV-positive nodal T-follicular helper cell lymphoma, angioimmunoblastic type (EBV+nTFHL-AI), and primary cutaneous T-cell lymphoma (CTCL). EBV-positive hematological malignancies are characterized by poor prognosis and limited therapeutic options, and there are currently no approved EBV-specific therapies. KSD-101 is a novel dendritic cell vaccine loaded with EBV-associated tumor-like composite antigens, which possesses strong antigen-presenting capacity and can initiate EBV-specific T-cell immunity. This study aims to investigate the real-world clinical efficacy and safety of KSD-101, providing an important reference for optimizing its clinical application, as well as theoretical support for the further development of novel therapeutic strategies.

This is a Phase 1/Phase 2 open-label, single-arm clinical study of GP350 CAR-T for Relapse/Refractory and Epstein-Barr virus infection associated lymphoid neoplasms. Each participant will undergo leukapheresis after enrolment, receive treatment of the conditioning chemotherapy, and an intravenous infusion of CAR-T cells. Each participant will proceed through the following study procedures: * Screening * Enrollment/Leukapheresis * Conditioning chemotherapy * CAR T treatment * Post-treatment assessment * Long-term follow-up
