Brief summary
This single arm, open-label, multi-center clinical trial is studying CD19 targeted chimeric antigen receptor T cells therapy in treating patients with CD19 positive malignant B-cell derived leukemia and lymphoma that is relapsed (after stem cell transplantation or chemotherapy) or refractory to chemotherapy.
Detailed description
This single arm, open-label, multi-center clinical trial is studying CD19 targeted chimeric antigen receptor T cells therapy in treating patients with CD19 positive malignant B-cell derived leukemia and lymphoma that is relapsed (after stem cell transplantation or chemotherapy) or refractory to chemotherapy. When patients enroll in this trial, autologous CD19CART cells were generated from the mononuclear cells of the patient's peripheral blood (PB). During the term of cell preparation of CD19CART cells, patients will receive a conditioning regimen. One day after completing conditioning regimen, the patient will be given infusions of CD19CART cells into the vein over a period of 1 to 3 days. Patients will be monitored for a response, toxic effects, and the expansion and persistence of circulating CD19CART cells.
Interventions
BIOLOGICALCD19CART
Patients will be given infusions of CD19CART cells into the vein over a period of 1 to 3 days. The target dose range administered in this study is 1x10e5-1x10e7 CD19CART cells/kg. Patients will be monitored for a response, toxic effects, and the expansion and persistence of circulating CD19CART cells.
