研究目的:

评估在长期接受 BTKi 持续治疗的 CLL 患者是否可通过维奈克拉桥接治疗达到深度缓解后停药并长期维持 PFS。 1、主要目的:最佳 uMRD 率:治疗结束前连续两次检测达到 uMRD 的患者比率。 2、次要目的:无进展生存期(PFS):治疗结束至疾病进展或死亡的时间。  

Objectives of Study:

To evaluate whether patients with CLL who have received long-term continuous BTKi therapy can achieve deep remission followed by treatment discontinuation and maintain durable progression-free survival (PFS) via Venetoclax bridging therapy. 1.Primary Objective: Best undetectable Minimal Residual Disease (uMRD) rate: the proportion of patients who achieve two consecutive undetectable MRD levels prior to treatment cessation. 2.Secondary Objective: PFS: the time from treatment discontinuation to disease progression or death.
