简要总结
This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with advanced hepatobiliary-pancreatic cancers. Autologous TILs are expanded from tumor resections or biopsies and infused i.v. into the patient after NMA lymphodepletion treatment with hydroxychloroquine(600mg,single-dose) and cyclophosphamide.

研究组 & 干预措施
Tumor Infiltrating Lymphocytes
1x10^9-5x10^10 in vitro expanded autologous TILs will be infused i.v. to patients with advanced hepatobiliary-pancreatic cancers after NMA lymphodepletion treatment with hydroxychloroquine(600mg,single-dose) and cyclophosphamide.
干预措施: Tumor Infiltrating Lymphocyte (Biological)
结局指标
主要结局
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.
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 GC101 TIL treatment and the subsequent disease progression per RECIST 1.1
Adverse Events (AE)
时间窗: up to 6 months
To characterize the safety profile of GC101 TIL in patients with advanced hepatobiliary-pancreatic cancers as assessed by incidence of adverse events.
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 TIL infusion，PET/CT scan will be performed at 6 weeks after TIL infusion, and than every 6 weeks for 6 months, and then every 6 months after that for up to 3 years)
Overall Survival (OS)
时间窗: Up to 36 months
