Study Details

Study Description

Brief Summary

This study is to investigate the safety and efficacy of signal switch receptor modified TIL (GC201 TIL) in patients with advanced gynecologic tumors. Autologous TILs from tumor resections or biopsies are first gene modified(TGF-β receptor or PD-1 gene modified TILs which could transfer the suppression signal surrounding the microenvironment of tumor bed into persistent T cell activation signal) and than expanded before i.v. infusion into the patient after NMA lymphodepletion treatment with fludarabine and cyclophosphamide.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Signal Switch Receptor Modified TIL

2x10^8-1x10^10 in vitro expanded autologous PD-1 or TGF-β signal switch receptor modified TIL (GC201 TIL) will be infused i.v. to patients with advanced gynecologic tumors after NMA lymphodepletion treatment with fludarabine and cyclophosphamide.

Biological: Signal Switch Receptor Modified TIL
Adoptive transfer of 2x10^8-1x10^10 autologous signal switch receptor modified TILs to patients i.v. in 30-120 minutes.

Outcome Measures

Primary Outcome Measures

  1. Adverse Events (AE) [Up to 6 months]

    To characterize the safety profile of Signal Switch Receptor Modified TIL (GC201 TIL) in patients with advanced gynecologic tumors as assessed by incidence of adverse events related to GC201 TIL infusion.

  2. Objective Response Rate (ORR) [Up to 36 months]

    Proportion of patients with response per Response Evaluation Criteria in Solid Tumors (RECIST v1.1): ORR (proportion of patients) = # with CR + # with PR / # with CR + # with PR + # with SD + # with PD. ( Except baseline evaluation within 28 days before TIL infusion,PET/CT scan will be performed at 6 weeks after GC201 TIL infusion, and than every 6 weeks for 6 months, and then every 6 months after that for up to 3 years)

  3. 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 v1.1: DCR (proportion of patients) = # with CR + # with PR + # with SD / # with CR + # with PR + # with SD + # with PD.

  4. 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

  5. Progression-Free Survival (PFS) [Up to 36 months]

    The time length between GC201 TIL infusion and confirmed subsequent disease progression according to RECIST 1.1

  6. Overall Survival (OS) [Up to 36 months ]]

    The length of time from the date of the start of GC201 TIL treatment that the patients are still alive

Secondary Outcome Measures

  1. Change in Quality of Life [Up to 36 months]

    Comparison of patients' quality of life before and after GC201 TIL treatment as assessed by the EORTC QLQ-30 (V3.0).
