This is an open-label, multicenter, phase 1 study to determine the safety and antitumor activity of BZ019 in adult patients with R/R large B cell lymphoma (DLBCL),including: DLBCL, not otherwise specified (NOS), transformed DLBCL, high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements and primary mediastinal B-cell lymphoma (PMBCL).The safety and efficacy of a single dose of different target doses of BZ019 will be evaluated in the dose-escalation phase and dose-expansion phase.~Upon enrollment, subjects will undergo leukapheresis to enable BZ019 product generation. A baseline tumor biopsy (in subjects with accessible disease) and bone marrow aspirate and biopsy will be obtained.~Upon successful BZ019 product generation, subjects will enter the treatment phase and receive BZ019 infusion. A completed treatment program will include lymphodepleting chemotherapy with fludarabine and cyclophosphamide (flu/cy) followed by single-dose of BZ019 infusion. BZ019 will be administered 2 to 14 days after the completion of lymphodepleting chemotherapy.~After the infusion of BZ019, subjects will be in the follow-up period upon 12 months for evaluation the safety and efficacy of BZ019. Subjects will be followed for long-term safety, overall survival even after disease progression.
This is an open-label, multicenter, dose-escalation phase 1 study to determine the safety and efficacy of BZ019 in relapsed or refractory CD19+ B-cell Lymphoma.
