Clinical Trial Summary

This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with malignant refractory/relapsed gastrointestinal 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.

Primary	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
Primary	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
Primary	Progression-Free Survival (PFS)	The time length between TIL infusion and confirmed subsequent disease progression according to RECIST 1.1	Up to 36 months
Primary	Overall Survival (OS)	The length of time from the date of the start of TIL treatment that the patients are still alive	Up to 36 months
