The Maximum Tolerated Dose [ Time Frame: 8 weeks ]
Verify the MTD of TCR-T cells for LMP2 antigen for treatment. The first nine patients enrolled in this project will be infused in a dose-climbing approach, with every three patients as a group. The first group of patients returned to 5e+6/kg TCR-T cells, the second group returned to 1e+7/kg TCR-T cells, and the third group returned to 5e+7/kg TCR-T cells. The remaining 11 patients will infused with TCR-Ts in the maximum tolerated dose

Brief Title  ICMJE LMP2-Specific IL12-secreting TCR-T Cells in the Treatment of EBV-Positive Metastatic/Refractory Nasopharyngeal Carcinoma
Official Title  ICMJE Single-Arm Trial of LMP2-Specific TCR-T Cells With IL12 Auto-secreted Element in the Treatment of EBV-Positive Head and Neck Carcinoma Metastatic/Refractory Nasopharyngeal Carcinoma
Brief Summary Epstein-Barr virus (EBV) infections is known to be a high-risk factor to induce cervical cancers. To date, EBV-related nasopharyngeal carcinoma (NPC) is still a major concern in east Asia, especially in China. Concurrent therapies for NPC have limited response rate and high chance of relapse. However, EBV-induced cancers provided an ideal target for T cell-based immunotherapy due to the non-self origins. Engineered T cells bearing a TCR (TCR-T) that can specifically recognize the presented LMP2-epitope become a viable approach to treat this type of cancer. Though engineered T therapies have been well-recognized in hematological cancers, solid cancer treatment has been a major hurdle due to the immune-suppressive tumor microenvironment. Interleukin 12 (IL-12) seemed to represent the ideal candidate for tumor immunotherapy, due to its ability to activate both innate (NK cells) and adaptive (cytotoxic T lymphocytes) immunities. several clinical studies have been initiated in which IL-12 is applied as an adjuvant in cancer vaccines, in gene therapy including locoregional injections of IL-12 plasmid and in the form of tumor-targeting immunocytokines (IL-12 fused to monoclonal antibodies). Therefore, TCR-T cells armed with a IL12-secretion element could further enhance the efficacy of TCR-T in solid cancers.
