Study on TIL for the Treatment of r/r Gynecologic Tumors
Study Details
Study Description
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tumor Infiltrating Lymphocytes (TIL) 1x10^9-3x10^11 in vitro expanded autologous TILs will be infused i.v. to patients with relapsed/refractory malignant gynecological tumors after NMA lymphodepletion treatment with fludarabine and cyclophosphamide. PD-1 checkpoint inhibitor would be applied as combination treatment to those patients. |
Biological: Tumor Infiltrating Lymphocytes (TIL)
Adoptive transfer of 1x10^9-3x10^11 autologous TILs to patients i.v. in 30-120 minutes.

Outcome Measures
Primary Outcome Measures
- Objective Response Rate (ORR) [Up to 36 months]
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)
- Disease Control Rate (DCR） [Up to 36 months]
Percentage of patients that meet CR, PR and SD criteria set in this study according to RECIST 1.1
- Duration of Response (DOR) [Up to 36 months]
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
- Progression-Free Survival (PFS) [Up to 36 months]
The time length between TIL infusion and confirmed subsequent disease progression according to RECIST 1.1
- Overall Survival (OS) [Up to 36 months]
The length of time from the date of the start of TIL treatment that the patients are still alive
Secondary Outcome Measures
- Complete Response(CR) [Up to 36 months]
Patients with complete response per RECIST 1.1 to TIL treatment
- Partial Response (PR) [Up to 36 months]
Percentage of patients with partial response per RECIST 1.1 to TIL treatment
- Stable Disease (SD) [Up to 36 months]
Patients with stable disease per RECIST 1.1 to TIL treatment
- Progressive Disease (PD) [Up to 36 months]
Patients with progressive disease per RECIST 1.1 to TIL treatment
- Change in Quality of Life [Up to 36 months]
Comparison of patients' quality of life before and after TIL treatment
