Exclusion Criteria:

    • Participants positive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) may enroll if HBV DNA level is below the lower limit of quantification (LLOQ) of the local study laboratory.
    • Participants positive for HCV antibody may enroll if HCV RNA level is below the LLOQ of the local study laboratory.
    • Participants with EBV DNA above the laboratory LLOQ may enroll if the Investigator assesses the viremia is tumor-related and the infection is non-active.
    • Carriers enrolled in the study shall receive antiviral therapy at the Investigator's discretion, with regular quantitative nucleic acid testing scheduled throughout the study period.

  • 12. Use of anti angiogenic agents such as bevacizumab within 4 weeks before surgical sampling.

  • 13. Previous allogeneic bone marrow transplantation or solid organ transplantation.

  • 14. Receipt of systemic anti tumor therapy within 4 weeks prior to lymphodepleting chemotherapy, except for the following:

    • If prior small molecule targeted therapy was administered, an interval of no less than 5 half lives of the agent between the end of such therapy and the anticipated date of lymphodepleting chemotherapy is required for enrolment.

  • 15. Prior receipt of genetically modified or gene edited cell therapy products (excluding non genetically modified autologous immune cell therapy products administered more than 1 year before the date of cell infusion).

  • 16. History of hypersensitivity reaction to any component of investigational products to be used in the study, including but not limited to autologous TIL, cyclophosphamide, fludarabine, IL-2, dimethyl sulfoxide (DMSO), human serum albumin (HSA), dextran 40, antibiotics (β-lactam antibiotics, gentamicin).

  • 18. Prior immune therapy related adverse events of Grade 3 or higher that have not recovered to CTCAE Grade 1 or less within 28 days; or any other disease or medical condition (any other illness, metabolic disorder, physical finding abnormality or laboratory abnormality) that would raise reasonable concerns prohibiting the use of investigational product, confound the interpretation of study results, or place the participant at high risk of treatment related complications.

  • 19. Pregnant or lactating women; or women with plans for pregnancy, conception or lactation within 1 year after the end of study treatment.

  • 20. Receipt of other investigational medicinal products within 4 weeks prior to lymphodepleting chemotherapy, or plan to receive other investigational medicinal products during the study.
