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;

13. A subject who is pregnant or breastfeeding, or who is planning a pregnancy during or
after 2 months of treatment;

14. Subjects who are women of childbearing age who are reluctant to receive
high-efficiency contraception (according to institutional standards) during treatment
and at least 2 months after the end of treatment. Female subjects of childbearing age
are required to provide a negative result of a serum or urine pregnancy test within 48
hours prior to treatment;

15. There are active or uncontrollable infections requiring systemic treatment within 14
or 14 days prior to grouping;

16. Subjects who are unwilling or unable to comply with the research requirements.
