Single arm 

研究目的:

主要目的:评估利沙托克拉进行桥接治疗是否能够实现深度缓解及停药维持长期的PFS。 次要目的:评估利沙托克拉桥接治疗(包括导入治疗和联合阶段)的安全性;探索预测停药成功(uMRD及长期PFS)的基线特征(年龄、临床分期等)生物学标志,如IGHV状态、TP53突变、MRD动力学、BTKi种类、BTKi前期治疗时间、治疗线数等。  

Objectives of Study:

Primary Objective: To evaluate whether bridging therapy with liso-cel can achieve deep remission and allow for treatment discontinuation while maintaining long-term progression-free survival (PFS).Secondary Objectives:To assess the safety of liso-cel bridging therapy, including the lead-in treatment and combination phases.To explore baseline characteristics (e.g., age, clinical stage) and biological markers that may predict successful treatment discontinuation (defined as undetectable minimal residual disease [uMRD] and sustained long-term PFS). These exploratory markers include IGHV status, TP53 mutation, MRD kinetics, type of prior BTK inhibitor (BTKi), duration of prior BTKi therapy, and line of therapy.
