Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main purpse of this study is to evaluate the safety of KSD-101 in patients with EBV-associated Nasopharyngeal Carcinoma,to evaluate the initial clinical outcomes and evaluate the immune response to KSD-101 for the treatment in Patients with EBV-associated Nasopharyngeal Carcinoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single-center, single-arm, open, multiple-dose clinical study evaluating the safety, preliminary efficacy, and immune response of KSD-101 for the treatment of patients with EBV-associated nasopharyngeal carcinoma.

Approximately 120 mL of PBMCs is collected from subjects. The collected PBMCs are transported to the manufacturing facility for the preparation of KSD-101. Subjects return to the study site for subsequent visits at investigator-notified times.

1. KSD-101 route of administration: subcutaneous injection.
2. KSD-101 treatment dose: 5.0 × 10\^6 cells/dose.
3. KSD-101 treatment frequency: once every 2 weeks for a total of 3-5 times. The 4th and 5th times are booster treatments, which need to be decided by the investigator according to the condition of the subjects.

9.Patients' corresponding lymph node region can accommodate subcutaneous injections.

10.Expected survival ≥ 3 months.

Exclusion Criteria

1. Patients receiving any anti-tumor therapy such as chemotherapy, radiotherapy, immunosuppressive therapy, etc. within 4 weeks prior to mono-collection.
2. Women who are pregnant (positive urine/blood pregnancy test), breastfeeding, or men or women who are planning to conceive within the last 1 year.

4. Patients with central nervous system pathology (e.g., cerebral edema, need for hormonal intervention, or progression of brain metastases).
5. Patients with uncontrollable infectious disease within 4 weeks prior to enrollment, or with active tuberculosis or on anti-tuberculosis therapy. (\< CTCAE grade 2 genitourinary infections and upper respiratory tract infections, except EBV infections).
6. Patients have a serious underlying disease (cardiovascular disease, respiratory disease, renal insufficiency, coagulation abnormality, autoimmune disease or immunodeficiency disease, etc.).
7. Other active malignant tumors within the past 3 years, unless they are curable tumors and have been significantly cured, such as basal or squamous cell carcinoma, carcinoma in situ of the uterine cervix or breast.
8. Subjects who have undergone major surgery or severe trauma within 4 weeks prior to enrollment or are expected to require major surgical intervention (i.e., surgery requiring the assistance of endotracheal anesthesia) during the study period.
