Clinical Trial Summary

20 participants are expected to be enrolled for the Phase Ib clinical trial，this trail is expected to be finished in 20 months.

Description:

This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with advanced melanoma. Autologous TILs are expanded from tumor resections or biopsies and infused i.v. into the patient after NMA lymphodepletion treatment with hydroxychloroquine and cyclophosphamide.
