A Single-arm, Open, Exploratory Clinical Study of Allogeneic CAR-T Cells in the Treatment of Relapsed/Refractory Brain Gliomas With Positive CD70 Expression
Trial Parameters
Brief Summary
The goal of this clinical trial is to learn if allogeneic CAR-T cells can treat patients with advanced gliomas. The main questions it aims to answer are: Evaluate the safety of allogeneic CAR-T cells in the treatment of advanced gliomas. To evaluate the effectiveness of allogeneic CAR-T cells in the treatment of advanced gliomas and to study its immunological properties in patients.
