Brief Summary

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

This is the second stage of the previous anti-CD19 CAR-T therapy (NCT02965092). The study aims to evaluate the safety and efficacy of consolidative allo-HSCT following CAR-T therapy in patients with relapsed or refractory B cell Malignancies.

Detailed Description

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

Anti-CD19 CAR-T therapy has been confirmed effective for relapsed/refractory B-cell malignancies. However, its ability to keep patients in maintained remission is limited. In order to keep patients in long-term remissions, patients who had achieved MRD-negative complete remissions through CAR-T therapy (NCT02965092) will, on their own accord, receive allo-HSCT if there are no previous HSCT, contraindications, and other restrictions.
