PRIMARY OBJECTIVES:
- To evaluate the feasibility and safety of universal dual specificity CD19 and CD20 or CD22 CAR-T cells in patients with relapsed or refractory leukemia and lymphoma.
- To evaluate the duration of in vivo persistence of adoptively transferred T cells, and the phenotype of persisting T cells. Real Time polymerase chain receptor (RT-PCR) and Flow cytometry(FCM) analysis of PB,BM and lymph node will be used to detect and quantify survival of universal dual specificity CD19 and CD20 or CD22 CAR-T cells over time.
-
SECONDARY OBJECTIVES:
- For patients with detectable disease, measure anti-tumor response due to universal dual specificity CD19 and CD20 or CD22 CAR-T cell infusions.
- Determine if cellular or humoral host immunity develops against the murine anti-CD19, and assess correlation with loss of detectable universal dual specificity CD19 and CD20 or CD22 CAR-T cells (loss of engraftment).
The CAR-T cells will be administered by i.v. injection over 20-30 minutes as a using a "split dose" approach to dosing: 10% on day 0, 30% on day 1 and 60% on day 2.
