A Study of GC101 TIL in r/r Gastrointestinal Tumors (10hospital)

Recruiting now · Early Phase 1

Conditions studied: Gastrointestinal Tumor

In brief

This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with malignant refractory/relapsed gastrointestinal tumors. Autologous TILs are expanded from tumor resections or biopsies and infused i.v. into the patient after NMA lymphodepletion treatment with hydroxychloroquine(600mg,single-dose) and cyclophosphamide.
