Study on TIL for the Treatment of r/r Gynecologic Tumors

Study Overview
=================
Brief Summary
-----------------
This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with malignant refractory/relapsed gynecologic tumors. Autologous TILs are expanded from tumor resections or biopsies and infused i.v. into the patient after NMA lymphodepletion treatment with fludarabine and cyclophosphamide.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective Response Rate (ORR) | To evaluate the efficacy of TIL infusion in patients as determined by objective response rate (ORR), which contains complete response (CR) and partial response (PR), using the RECIST v1.1, as assessed by the Investigator. ( CT Scan at 4-6 weeks after TIL infusion, and than every 4-6 weeks for 1 year, and then every six months after that for up to 3 years) | Up to 36 months | 
| Disease Control Rate (DCR） | Percentage of patients that meet CR, PR and SD criteria set in this study according to RECIST 1.1 | Up to 36 months | 
| Duration of Response (DOR) | The time length between the first confirmed objective response per RECIST 1.1 to the treatment and the subsequent disease progression per RECIST 1.1 | Up to 36 months | 
| Progression-Free Survival (PFS) | The time length between TIL infusion and confirmed subsequent disease progression according to RECIST 1.1 | Up to 36 months | 
| Overall Survival (OS) | The length of time from the date of the start of TIL treatment that the patients are still alive | Up to 36 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
