ADP-TILIL7

The primary objective of this Phase 1 clinical trial is to evaluate the feasibility and tolerability of a novel generation of gene-modified tumor infiltrating lymphocytes (TILs) in a cohort of 10 patients aged 18-75 diagnosed with unresectable or metastatic melanoma. TILs will undergo transduction with the Interleukin-7 (IL-7) gene, for IL-7 production upon antigen engagement.
Participants will undergo:
* screening
* tumor operation following autologous TIL production (incl. transduction) - takes approximately 4-6 weeks
* admission for lymphodepleting chemotherapy (Cyclophosphamide and Fludarabine phosphate), TIL infusion and high-dose IL-2 infusions for a maximum of 6 doses
* Following treatment, patients will undergo systematic and regularly planned assessments, encompassing clinical evaluation, biochemistry analyses, and PET/CT scans. This thorough follow-up regimen will be continued until any of the following events occur: progressive disease, withdrawal from study, or end of study, which spans a duration of 15 years for trials involving genetically modified organisms.
