简要总结
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.
详细描述
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.
