Brief Summary

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

Clinical Trial for the Safety and Efficacy of Sequential CD19 and CD22 CAR-T Therapy for Adult Patients With Newly Diagnosed Ph Chromosome Negative B-cell Acute Lymphoblastic Leukemia

Detailed Description

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

This is a prospective, single arm study. To evaluate the safety and efficacy of sequential CD19 and CD22 CAR-T cells in the treatment of adult newly diagnosed Ph chromosome negative B-cell acute lymphoblastic leukemia. The main endpoints were dose limiting toxicity (DLT) and incidence of adverse events (TEAEs).
