Brief Summary

Epstein-Barr virus (EBV) infections is known to be a high-risk factor to induce nasopharyngeal cancers. To date, EBV-related head and neck squamous cell carcinoma (HNSCC) is still a major concern in east Asia, especially in China. Concurrent therapies for HNSCC 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 EBV antigen 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. One key mechanism of tumor-elicited suppression is the PDL1-PD1 interaction which induces T cell exhaustion. Therefore, TCR-T cells armed with a PD1 antagonist could further enhance the efficacy of TCR-T in solid cancers.

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
The Maximum Tolerated Dose	Verify the MTD of TCR-T cells for EBV antigen for treatment. 18 patients will be enrolled in this project, using a dose-escalation approach. The first group of patients will receive 5x10e6/kg TCR-T cells, the second group will receive 1x10e7/kg TCR-T cells, the third group will receive 5x10e7/kg TCR-T cells, the forth group will receive 1x10e8/kg. After confirmation of safety for 5×10e7 dose group, we then added IL-2 on this dose level for consecutive 6 patients. The remaining 6 pts are for enrollment of 1×10e8/kg dose level.	8 weeks
