EBV-AST Cell Injection for EBV-Associated Lymphoproliferative Disorders

NCT07450391 · Status: RECRUITING · Phase: PHASE1/PHASE2 · Type: INTERVENTIONAL · Enrollment: 18

Summary

This is an investigator-initiated, open-label, single-arm, dose-escalation exploratory study to evaluate the safety, tolerability, and preliminary efficacy of EBV-AST cell injection in adults with EBV-associated lymphoproliferative disorders, including post-transplant lymphoproliferative disease (PTLD) and EBV-positive lymphomas. Participants will receive EBV-AST cell infusions intravenously every 2 weeks for up to 3 infusions at escalating dose levels. The primary objective is to assess safety and determine a potential optimal biologically active dose. Secondary objectives include preliminary tumor response and EBV-related virologic outcomes, as well as cellular PK/PD.

Interventions

BIOLOGICAL

EBV-AST Cell Injection

EBV-AST is an Epstein-Barr virus (EBV) antigen-specific cytotoxic T-lymphocyte product generated by ex vivo stimulation and expansion of T cells using peptide-loaded dendritic cells. EBV-AST is administered by intravenous infusion every 2 weeks for up to 3 infusions at escalating dose levels (3×10\^5, 3×10\^6, or 3×10\^7 cells/kg per infusion), according to the protocol-defined dose-escalation design.
