B-cell Acute Lymphoblastic Leukemia, B Cell Lymphoma
Conditions
Brief summary
The primary objective of this study is to evaluate the safety and clinical activity of anti-CD19 Chimeric Antigen Receptor T cells (KD-019 CAR-T)infusion in the treatment of relapsed/refractory B-cell Lymphoma and B-cell acute lymphoblastic leukemia (B-ALL).
Detailed description
The investigators designed an KD-019 Chimeric Antigen Receptor(CAR) with FMC63 single-chain antibody fragment (Scfv). This CAR has a CD8 hinge and transmembrane domains and a 4-1BB costimulatory domain; T cells expressing this CAR release relatively low levels of cytokines. Subjects with relapsed/refractory CD19-positive B-cell Lymphoma and B-ALL can participate if all eligibility criteria are met. Subjects receive chemotherapy prior to the infusion of KD-019 CAR-T cells. After the infusion, subjects will accept follow-up for side effects and effect of KD-019 CAR-T cells by the sponsor. Study procedures may be performed while hospitalized.
