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 retroviral 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.
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
