A Study of Anti-CD19 CAR-T Cell Immunotherapy for Refractory /Relapsed B Cell Malignancies
June 17, 2017 updated by: Second Affiliated Hospital of Guangzhou Medical University
A Prospective, Multicenter, Single-Arm Study of Anti-CD19 CAR-T Cell Immunotherapy for Refractory /Relapsed B Cell Malignancies
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.
Study Overview
Status
Unknown
Intervention / Treatment
Detailed Description
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.
