Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multi-center, single arm, open-label, phase I study to determine the safety and effectiveness of EBV-TCR-T cell immunotherapy in treating EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) or EBV infection

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Epstein-Barr virus (EBV) is a widely disseminated herpesvirus that is spread by intimate contact between susceptible persons and asymptomatic EBV shedders. The inability to control EBV infection can lead to some patients developing EBV-positive B-cell lymphomas, chronic active EBV infections, and hemophagocytic lymphohistiocytosis (HLH). In this prospective study, HLA-A\*02:01/11:01/24:02-restricted EBV-specific T cell receptor (TCR) will be introduced into the T cells of donors by ex vivo lentiviral transduction to generate EBV-TCR-T cells. An escalated dose ranging from 1×10\^6/kg to 1×10\^8/kg of EBV-TCR-T cells will be infused into patients with EBV-HLH or EBV infection. The safety, efficacy, pharmacokinetics and cytokine levels of allogenic EBV-TCR-T cell therapy will be evaluated.
