简要总结
This study is to investigate the safety and efficacy on TIL engineered with membrane-binding cytokine (GC203 TIL) for the treatment of patients with advanced gynecologic tumors. Autologous TILs from tumor resections or biopsies are first gene modified (engineered with membrane-binding cytokine) and than expanded before i.v. infusion into the patient after NMA lymphodepletion treatment with cyclophosphamide.

研究组 & 干预措施
Membrane Bound Cytokine Modified TIL
2x10^8-1x10^10 in vitro expanded autologous TIL engineered with membrane-binding cytokine (GC203 TIL) will be infused i.v. to patients with advanced gynecologic tumors after NMA lymphodepletion treatment with cyclophosphamide.
干预措施: Membrane Bound Cytokine Modified TIL (Biological)
结局指标
主要结局
Adverse Events (AE)
时间窗: Up to 6 months
To characterize the safety profile of TIL engineered with membrane-binding cytokine (GC203 TIL) in patients with advanced gynecologic tumors as assessed by incidence of adverse events related to GC203 TIL infusion.
Objective Response Rate (ORR)
时间窗: 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 GC203 TIL infusion，PET/CT scan will be performed at 6 weeks after GC203 TIL infusion, and than every 6 weeks for 6 months, and then every 6 months after that for up to 3 years)
Duration of Response (DOR)
时间窗: 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)
时间窗: Up to 36 months
The time length between GC203 TIL infusion and confirmed subsequent disease progression according to RECIST 1.1
Disease Control Rate (DCR）
时间窗: 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.
Overall Survival (OS)
时间窗: Up to 36 months
The length of time from the date of the start of GC203 TIL treatment that the patients are still alive
次要结局
