A Clinical Safety and Efficacy Study on TIL for the Treatment of r/r Gynecologic Tumors

shiyuanfuke000

This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with malignant refractory/relapsed gynecologic tumors. Autologous TILs are expanded from tumor resections or biopsies and infused i.v. into the patient after NMA lymphodepletion treatment with fludarabine and cyclophosphamide.
