Brief Summary

In this study, a single-arm, open-labeled clinical trial will be performed to determine the safety and efficacy of EBV TCR-T cells in the treatment of recurrent/metastatic nasopharyngeal carcinoma with positive EBV infection in the Chinese population.

Detailed Description

All enrolled subjects will be infused with EBV TCR-T cells. The project which enrolls 27 patients, according to the patient's HLA subtypes will be divided into HLA-A2, HLA-A11, HLA-A24 three groups, 9 patients in each group. Using a dose climbing method, each group will be divided into three dose subgroups. In the first dose subgroup, 5×106/kg TCR-T cells will be returned, and in the second dose subgroup, 1×107/kg TCR-T cells will be returned. The third dose subgroup 5 x 107/kg TCR-T cells will be returned.

Eligibility Criteria

Inclusion Criteria

1. Patients with nasopharyngeal carcinoma diagnosed by pathology and EBV infection (EBERs positive ) ; 2.18-70 years old; 3.MHC-I is HLA-A2, HLA-A11 or HLA-A24 subtype; 4. Progression after second-line platinum-containing chemotherapy regimen, recurrent/metastatic nasopharyngeal carcinoma patients who are inoperable and non-radiable; 5. Based on the Response Evaluation Criteria in Solid Tumors version (RECIST 1.1), there are ≥ 1 measurable target lesions; 6. Expected survival time is more than 12 weeks; 7. ECOG score 0-2 points; 8. Patients with good bone marrow, kidney, liver, and heart, and lung function 9. Can establish the venous access required for the collection, no contraindications for white blood cell collection; 10. Male and female patients of the appropriate age must adopt a reliable method of contraception; 11. Those who understand the trial and have signed an informed consent form.

Exclusion Criteria

1. Patients with symptomatic brain metastasis;

2. Other malignant tumors other than nasopharyngeal carcinoma within 5 years prior to enrollment, in addition to appropriate treatment of cervical carcinoma in situ, cutaneous basal or squamous cell carcinoma, localized prostate cancer or ductal carcinoma in situ after radical surgery ;

3. Hepatitis B or hepatitis C active period, HIV-infected;

4. Any other uncontrolled active disease that impedes participation in the trial;

5. Patients with severe heart and cerebrovascular diseases such as coronary heart disease, angina pectoris, myocardial infarction, arrhythmia, cerebral thrombosis, and cerebral hemorrhage;

6. 2-3 grade hypertension or patients with poorly controlled hypertension;

7. Those with a history of mental illness that are difficult to control;

8. The investigator believes that it is not appropriate to participate in the trial;

9. Those who have been using immunosuppressive agents for a long time after organ transplantation, except for recent or current inhaled corticosteroids;

10. In the opinion of the investigator, the presence of medical history or mental state history or laboratory abnormalities may increase the risk associated with participating in the study or study drug administration, or may interfere with the interpretation of the results;

11. Screening indicates that the target cell transfection rate is less than 30%, or the T cell expansion is insufficient (less than 5 times) under CD3/CD28 stimulation conditions;

12. Unstable pulmonary embolism, deep vein thrombosis, or other major arterial/venous thromboembolic events occurred 30 days or 30 days prior to grouping. If receiving anticoagulant therapy, the subject's therapeutic dose must be stable before grouping;
