5. Study Description

Brief Summary
This is a single center, open-label, 3+3 dose escalation, phase 1 study to evaluate the efficacy and safety of ET019003-T cells therapy for patients with relapsed/refractory CD19+ acute lymphoblastic leukemia and lymphoma.
Detailed Description
ET019003-T cells is a human anti-CD19 CAR-T cells by fusing the anti-CD19 antibody Fab domain with the transmembrane and intracellular domains from the γδTCR, which can avoid mispairing with the T cell's endogenous αβTCR chains. Meanwhile, an independent ET190L1-CSR(Chimeric Signaling Receptor) is added to ET019003-T cells in trans, which can bind CD19 to activate a novel costimulatory domain to further promote T cell proliferation and persistence. The trial is conducted to explore the safety and efficacy of ET019003-T cells in CD19+ Leukemia and Lymphoma.

Interventional Study Model
Single Group Assignment
Model Description
This study was a single-center, open-label, single-arm, non-randomized,3+3 dose escalation clinical trial.18 patients are separated into 9 leukemia and 9 lymphoma. Each disease has 3 groups by infusion dose level. Each dose group has 3 patients.If no DLT emerges in the group, then the next group uses the subsequent higher dose. If DLT emerges in a single subject in any dose level, 3 more subjects will be enrolled to the same dose level.The maximum dose could be extended.
