A Clinical Study to Evaluate the Safety and Efficacy of Anti-human CD 7 CAR-NK Cell Injection in Subjects With Relapsed and Refractory CD7-positive Hematological Malignancy

Summary

This study is a single-arm, open-label, dose-escalation clinical trial to explore the safety, tolerability, pharmacokinetics and pharmacodynamics characteristics of the drug; The efficacy of the study drug in subjects with relapsed/refractory CD7-positive hematological malignancies, and the expression of B cells, T cells, and NK cell subtypes in peripheral blood were preliminarily observed. At the same time, explporing the distribution of anti-human CD7 CAR-NK cells in tumor tissues after administration of anti-human CD7 CAR-NK cell injection, and evaluating the immunogenicity of anti-human CD7 CAR-NK cell injection . To evaluate the correlation between the proportion of CD7-positive tumor cells and the safety and efficacy of anti-human CD7 CAR-NK cell injection and the evaluation. To explore the pharmacokinetics (PK) and pharmacodynamics(PD) characteristics of bone marrow in Chinese medicine.
