To Evaluate the Safety of Autologous Tumor-infiltrating Lymphocytes(TILs) for the Treatment of Recurrent Ovarian Cancer

Primary outcomes

1. Evaluation of cytotoxicity of cells against cancer cells

   Time frame: Treatment period- 2 months, follow-up- 4 months after completion of treatment

   • Primary cancer cells isolated and cultured from a single cell of the same patient's tumor, or TIL cells cultured from the ovarian cancer cell line OVCAR3, are co-cultured in a CO2 incubator for 20 hours. After 20 hours, the cells are stained with 7AAD, and the cancer cell killing ability is analyzed using a flow cytometer
   • Measurement of IFN-γ secreted by T cells: CD8+ T cells inhibit tumor cell differentiation and enhance immune function by secreting IFN-γ. After co-culturing target cells and T cells, the pellet is used for cytotoxicity evaluation, and the culture medium is collected to measure the amount of secreted IFN-γ using ELISA.
   • Microscopic assay: After co-culturing fluorescently labeled primary cancer cells with fluorescently labeled enhanced T cells for 20 hours, the number of viable tumor cells is measured.

2. Evaluation of toxicity of protocol therapy including lymphodepletion, CHA-TIL, and high dose IL2

   Time frame: Treatment periods 2 months, follow-up 4 months after completion of treatment

   • Toxicity evaluation variables subject to analysis include adverse events, clinical laboratory test results (e.g., hematology, coagulation, serum analysis, and urinalysis), physical examination, and vital signs. Clinically significant changes from baseline will be summarized using descriptive statistics. The severity of adverse events will be graded according to CTCAE v5.0 and recorded in the case report form.
   • The overall frequency of adverse events (number of subjects and percentage), the worst reported severity, and the association with the investigational medicinal product will be recorded for each subject.
   • Serious adverse events are summarized in a similar manner. A list of deaths, SAEs, and AEs that lead to early termination or withdrawal from the clinical trial will also be provided.
   • For all AEs, a complete list will be presented including the subject number, clinical trial regimen, severity, severity, actions taken, outcome, association with the clinical trial treatment,
