Brief summary

This is a single-center, open-label and pragmatic clinical trial to evaluate the primary efficacy and safety of anti-CD19 chimeric antigen receptor (CAR)-modified T cells (CART-CD19) with concurrent BTK inhibitor in patients with relapsed or refractory B cell lymphoma

Detailed description

Anti-CD19 chimeric antigen receptor (CAR) T-cell has shown dramatical efficacy in B cell malignancies. And Bruton tyrosine kinase (BTK) inhibitor agents have been validated as an effective drug to treat B cell malignancies. Combined therapies comprising ibrutinib (a BTK inhibitor) and anti-CD19 CAR-T cells in patients with CLL after ibrutinib failure are considered feasible and safe. Ibrutinib is the first-generation BTK inhibitror and Zanubrutinib is the second-generation BTK inhibitor. Orelabrutinib is a newly developed BTK inhibitor with high selectivity and have received its approval in China. Autologous cells derived T cells are purified and transduced with a lentiviral vector encoding the humanized CD19 scFv. To evaluate whether the addition of BTK inhibitor (Ibrutinib, Zanubrutinib and Orelabrutinib) in anti-CD19 CAR-T cells therapy would further improve efficacy and safety, we intend to conduct this pragmatic clinical trial.

Interventions

DRUGBTK inhibitor+ Fludarabine-based chemotherapy + CAR-T-CD19 Cells

BTK inhibitor from enrollment to more than 90 days after CAR-T-CD19 infusion. Fludarabine-based lymphodepletion chemotherapy was followed by CART19 infusion at a dose of 1x10\^6/kg on day 0 and day 1 respectively.

DRUGFludarabine-based chemotherapy + CAR-T-CD19 Cells

Fludarabine-based lymphodepletion chemotherapy was followed by CART19 infusion at a dose of 1x10\^6/kg on day 0 and day 1 respectively.

Intervention model description

This study was a pragmatic clinical trial in which patients were divided into two groups, one receiving anti-CD19 CAR-T cells infusion, the other group receiving anti-CD19 CAR-T cells infusion and concurrent oral BTK inhibitor.
