Summary

This study will test whether anti-EBV autologous TCR-T cell injection is safe and effective for patients with relapsed or refractory EBV-positive lymphoma who have HLA-A11:01. Researchers will look at safety, tolerability, and the maximum tolerated dose or recommended dose for future studies. The study will also measure how the infused TCR-T cells expand and persist in the body, changes in EBV DNA levels and T-cell subgroups in the blood, and whether the treatment shows early signs of clinical benefit. Researchers will also explore whether the treatment causes an immune response against the infused cells.

Conditions

• NK/T-cell Lymphoma
• Peripheral T-cell Lymphoma (PTCL)
• DLBCL

Interventions

Type	Name	Description
DRUG	EBV TCR-T	After signing the informed consent form and completing screening according to the inclusion/exclusion criteria, eligible subjects will be sequentially assigned to the following dose cohorts of TCR-T cells (single administration): 1×10⁶ TCR-T cells/kg, 2.5×10⁶ TCR-T cells/kg, 5×10⁶ TCR-T cells/kg, and 10×10⁶ TCR-T cells/kg. The first dose cohort (1×10⁶ TCR-T cells/kg) will use a rapid titration approach. If no significant safety issues occur within 28 days after infusion-defined as ≥Grade 3 non-hematologic toxicity, Grade 4 hematologic toxicity lasting more than 28 days (excluding disease- or chemotherapy-related causes), ≥Grade 2 neurotoxicity, or ≥Grade 3 cytokine release syndrome (CRS)-the next dose cohort will be initiated. If a dose-limiting toxicity (DLT) occurs, evaluation will be performed after 6 subjects have been treated. The subsequent three dose cohorts will follow a "3+3" dose-escalation design, with 3-6 subjects per cohort receiving a single infusion. For subjects in th
