Study Overview
Brief 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.

- •Any uncertain factor that may affect the safety or compliance of the patient;
- •Other conditions considered unsuitable for enrollment by the investigator.
Arms & Interventions
cCTL experimental group
The planned treatment duration for each patient in the clinical trial is 2-4 months, with one cycle lasting 1 month. Each cycle will include multiple intravenous infusions of cCTL (generally 4-10 times), with treatment frequency ranging from one to three times per week (based on individual patient conditions, as determined by the investigator). The dose for each infusion is 2-5x10^7 cCTL cells per kg of body weight.
Intervention: cCTL treatment (Biological)
Outcomes
Primary Outcomes
Objective response rate (ORR)
Time Frame: From enrollment to the end of treatment at 8 weeks
Objective Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR). ORR was defined as the percentage of participants who had a Complete Response (Disappearance of all target lesions) or a Partial Response (≥30% decrease in the sum of the longest diameter of target lesions) using RECIST 1.1 based on BICR.
Secondary Outcomes
No secondary outcomes reported
