研究概览
简要总结
This is a Phase 1/1b, nonrandomized, open-label, parallel assignment, dose-escalation, and dose-expansion study to evaluate the safety and clinical activity of azer-cel, an allogeneic anti-CD19 CAR T, in adults with r/r B ALL, r/r B-cell NHL and CLL/SLL.
详细描述
This is a multicenter, nonrandomized, open-label, parallel assignment, dose-escalation, and dose-expansion study to evaluate the safety and tolerability, find an appropriate dose to optimize safety and efficacy, and evaluate clinical activity of azer-cel in participants with relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (B-ALL), non-Hodgkin lymphoma (NHL), and chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). Before initiating azer-cel, participants will be administered lymphodepletion (LD). At Day 0 of the Treatment Period, participants will receive an intravenous (IV) infusion of azer-cel potentially followed by interleukin-2 (IL-2). All participants will be monitored through D720 or progression. All participants who receive a dose of azer-cel will be asked to consent to a separate long-term follow-up (LTFU) study for up to 15 years after exiting this study.
