Exploratory Clinical Study of Autologous Tumor-infiltrating Lymphocyte Injection (GT201) for Advanced Gynecologic Tumors

Study Overview
=================
Brief Summary
-----------------
This study is a single-center, single-arm phase I clinical trial. A total of 24 26 subjects (20 evaluable cases are expected) from 1 cohort will be enrolled in this study. An autologous tumor-infiltrating lymphocyte therapy dosing regimen consisting of lymphodepleting chemotherapy (FC regimen: cyclophosphamide + fludarabine), infusion of autologous tumor-infiltrating lymphocyte injection, and interleukin-2 injection will be used.The study process is divided into: screening period, sampling and production period, clearing and chemotherapy period, treatment and observation period, and follow-up period

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety Profile Measured by Grade ≥3 TEAEs | To characterize the safety profile of autologous TIL injection（GT201) in patients with relapsed/metastatic advanced solid tumor as measured by the incidence of Grade ≥ 3 treatment-emergent adverse events (TEAEs) | 3 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective response rate | To evaluate efficacy parameters such Objective Response Rate (ORR) per RECIST 1.1, as assessed by the Investigator | 3 years | 
| Progression-free survival | To evaluate efficacy parameters such Progression-Free Survival (PFS) per RECIST 1.1, as assessed by the Investigator | 3 years | 
| Overall survival | To evaluate efficacy parameters such Overall Survival (OS) | 3 years |
