Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main purpose of this study is to explore the efficacy of CD19-targeted CAR-T cell therapy for minimal residual disease (MRD) in B-cell Malignancies after autologous stem cell transplantation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Relapse is a common cause of failure in patients with B-cell malignancies after autologous stem cell transplantation. CD19-targeted CAR-T cells showed excellent therapeutic efficiency in B-cell malignancies. Investigators attempt to treat minimal residual disease (MRD)-positive B-cell Malignancies after autologous stem cell transplantation by CD19-targeted CAR-T cells and hope to explore the therapeutic effects of CD19-targeted CAR-T cell therapy.
