Brief Summary

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

Autologous T cells engineered to express an anti-CD19 chimeric antigen receptor (CAR) will be infused back to patients with refractory /relapsed B cell malignancies, including lymphoma and leukemia. The patients will be monitored after infusion of anti-CD19 CAR-transduced T cells for safety,adverse events, persistence of anti-CD19 CAR-transduced T cells and treatment efficacy.

Detailed Description

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

Despite progress has been made to date in the treatment of patients with B cell malignancies, including leukemia and lymphoma, many patients with relapsed or refractory diseases do not respond to the standard treatments. It has been shown that anti-CD19 CAR-transduced T cells may be an effective approach to treat the relapsed or refractory diseases. The procedure involves collecting PBMCs from the patients and modifying the T cells to attack the malignant B cells. In this trial, autologous T cells engineered to express an anti-CD19 chimeric antigen receptor (CAR) containing the signaling domains of CD28 or 4-1BB and CD3-zeta will be infused back to patients with B cell malignancies, including lymphoma and leukemia. The patients will be pretreated with a lymphodepleting preconditioning regimen before the infusion of anti-CD19 CAR T cells, and will be monitored for safety, adverse events, persistence of anti-CD19 CAR-transduced T cells and the treatment efficacy.
