Safety and Efficacy of Anti-EBV Autologous TCR-T Cell Injection in Relapsed/Refractory EBV-Positive Lymphoma
Plain-language summary
This trial is testing EBV-specific T cells (immune cells trained to attack Epstein-Barr virus in lymphoma cells) for patients with extranodal NK/T-cell lymphoma (ENKTL) who have been newly diagnosed and have not yet received treatment as well as those whose disease has come back or stopped responding to prior treatment. This is an early Phase 1 trial, which means this is among the first tests of the treatment in patients, focusing on safety and dose. The study looks at both safety and how well the treatment controls the lymphoma. This trial does not currently have sites in the United States. The trial is currently recruiting patients.
Who can join (key eligibility)
- Age 18 Years to 70 Years years
- Newly diagnosed, not yet treated
- Must be well enough for treatment (adequate performance status)
Final eligibility is determined by the trial team. This list is a starting point only.
What's being tested
EBV TCR-T (DRUG): 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
