Summary

This study is a prospective, multicenter, open-label, single-arm phase II clinical trial evaluating the efficacy and safety of an MRD-guided, time-limited therapy with zanubrutinib combined with sonrotoclax in previously untreated high-risk CLL/SLL patients.

Conditions

  • CLL (Chronic Lymphocytic Leukemia)

Interventions

DRUG

Zanubrutinib and sonrotoclax

Zanubrutinib: 160 mg BID, orally, administered until Cycle 15, 21, or 27, and thereafter until discontinuation criteria are met, disease progression, or unacceptable toxicity.(28d/cycle) Sonrotoclax: Starting from Day 1 of Cycle 3, a 4-week dose-escalation regimen is administered until the target dose of 320 mg QD is reached, then administered orally until Cycle 15, 21, or 27, and thereafter until discontinuation criteria are met, disease progression, or unacceptable toxicity. All patients must complete at least 12 cycles of combination therapy with zanubrutinib and sonrotoclax (C4-C15), with a maximum of 24 cycles of combination therapy (C4-C27). If uMRD6 is not achieved after 24 cycles of combination therapy, patients will receive zanubrutinib monotherapy as maintenance. For patients in whom assessment is feasible, treatment discontinuation may be considered upon achieving uMRD6 at any time point. Otherwise, treatment will be continued until disease progression.
