A Study of GC101 TIL in Advanced Solid Tumors (TR)

A Clinical Study to Evaluate the Safety and Efficacy of Autologous Tumor Infiltrating Lymphocytes Injection in Patients With Advanced Malignant Solid Tumors

This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with Advanced malignant solid tumors.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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate (ORR)	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 GC101 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)	Up to 36 months
Adverse Events(AE)	To characterize the safety profile of GC101 TIL in patients with recurrent, metastatic, or persistent solid tumor as assessed by incidence of adverse events.	6 month

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Disease Control Rate (DCR）	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.	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 GC101 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 GC101-TIL treatment that the patients are still alive.	Up to 36 months
