Exploratory Clinical Study of cCTL in Combination With Immunotherapy for Advanced Gynecologic Malignancies

Summary

This study is a single-arm, open-label, interventional, and exploratory clinical trial,the goal of which is to evaluate the safety and clinical efficacy of the novel tumor-specific cytotoxic T lymphocyte (cCTL) injection in combination with immunotherapy for the treatment of advanced gynecologic malignancies.The trial will also explore the preliminary efficacy and immunological characteristics of this therapy in a small sample of patients. 5-20 participants will be enrolled.

2. Required use of immunosuppressive agents;
3. Receipt of tumor chemotherapy, radiotherapy, or second-degree or higher surgery within the past month;
4. History of other cancers, except for in situ cervical cancer, treated squamous cell carcinoma, or bladder epithelial tumors (Ta and TIS), or other malignancies that have undergone radical treatment (at least 5 years prior to enrollment);
