Universal 4SCAR7U Targeting CD7-positive Malignancies

Summary

The purpose of this clinical trial is to assess the feasibility, safety and efficacy of universal CAR T cells based on 4SCAR7U design against CD7-positive hematological malignancies using CD7 specific universal CAR T cells. The study also aims to learn more about the function of CD7 targeting CAR T cells and their persistence in patients of hematological malignancies.
