B Cell Malignancies Clinical Trial
Official title:
CD19/70 Bi-specific CAR-T Cells Targeting B Cell Malignancies
The purpose of this study is to assess the feasibility, safety and efficacy of CD19/70 bi-specific CAR-T cell therapy in patients with CD19 and/or CD70 positive B cell malignancies. Another goal of the study is to learn more about the safety and function of the anti-CD19/70 bi-specific CAR-T cells and their persistency in patients.
