Clinical Trial Summary

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.

Description:

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.
