Non-gene Edited Anti-CD7 CAR T Cells for Relapsed/Refractory T Cell Malignances

Non-gene Edited Anti-CD7 CAR T Cells for Relapsed/Refractory T Cell Malignances

This is a phase I, interventional, single arm, open label, treatment study to evaluate the safety and tolerability of non-gene edited anti-CD7 CAR (also called anti-CD7 CAR) T cells in patients with relapsed and/or refractory T cell lymphoma or leukemia

Anti-CD7 CAR is a chimeric antigen receptor immunotherapy treatment designed to treat leukemia/lymphoma expressing CD7 antigen. T-cell acute lymphoblastic leukemia, T-acute lymphoblastic lymphoma and T-cell non-Hodgkin lymphoma are a subset of leukemias and lymphomas that are positive for the surface protein CD7. The purpose of this study is to evaluate the efficacy and safety of anti-CD7 CAR T cells.
