Brief Summary | The study will evaluate safety and efficacy of a 4th generation chimeric antigen receptor gene-modified T cells targeting CD19 (4SCAR19) for patients with B cell malignancies. Clinical response and development of a standardized lentiviral vector and cell production protocol will be investigated. This is a phase I/II trial enrolling patients from multiple clinical centers. | ||||
Detailed Description | Background: T cells modified with lentiviral chimeric antigen receptor (CAR) gene have been studied in different clinical settings. Recent successes suggest that increased costimulatory signaling in the CAR design is critical for long term efficacy. Activation of T cell response from large tumor burden may induce a severe response. To increase safety, a novel design using an inducible caspase 9 fusion gene has been incorporated in the CAR gene. A 4th generation CAR lentiviral vector (4SCAR) carrying T cell costimulatory signals for CD28/CD27 plus an inducible apoptotic caspase 9 gene has been established. The study aims to evaluate the activities of a new CAR gene-modified T cells targeting CD19-positive tumors based on a CD19-specific single chain gene constructed 4SCAR (4SCAR19). Objective: To evaluate safety and efficacy of administrating 4SCAR19 T cells to patients with CD19 positive B cell malignancies following a cyclophosphamide/fludarabine based conditioning regimen. Eligibility: Patients older than 6-month-old with CD19 positive B cells malignancies that have recurred after or refractory to standard therapy and is deemed incurable using standard treatment. Design: Participants will be screened based on cancer cell phenotype analyzed using flow cytometry or immunohistochemical staining methods. Peripheral blood mononuclear cells (PBMC) will be obtained through apheresis, and T cells will be activated and modified to express the 4SCAR19 gene. On Day -5 to -7, PBMC will be activated and enriched for T cells, which will be followed by 4SCAR19 lentiviral transduction. The total cell preparation time is approximately 5-7 days. Participants will receive a preparative conditioning regimen comprising cyclophosphamide/fludarabine to prepare their immune system to accommodate the modified CAR T cells. The preparative regimen will be based on patient immune condition and consistent with standard chemotherapy conditioning regimen. Participants will receive an infusion of the modified 4SCAR19 T cells and closely followed up for treatment-related responses. Participants will be continuously monitored for CAR T cells and clinical responses at present timeline. |
