What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence and severity of adverse events (AEs)
Time Frame: Up to 1 years
Adverse events are graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0
Up to 1 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Objective Response
Time Frame: Up to 2 years
Participants displaying objective response associated with the treatment regimen per Response Evaluation Criteria in Solid Tumors (RECIST v.1.1). The best overall response is the best response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started). The patient's best response assignment will depend on the achievement of both measurement and confirmation criteria.
Up to 2 years
Progression-Free Survival (PFS)
Time Frame: Up to 2 years
The time length between TIL infusion and confirmed subsequent disease progression according to RECIST 1.1
Up to 2 years
The changes of the immunoreactivity during treatment
Time Frame: Up to 2 years
The changes from baseline of systemic immune Response markers: peripheral blood lymphocyte subtypes counts, cytokine, antigen-specific T-lymphocytes
Up to 2 years
Disease Control Rate (DCR)
Time Frame: Up to 2 years
Percentage of patients that meet CR, PR and SD criteria set in this study according to RECIST v1.1
Up to 2 years
