About this trial
The goal of this clinical trial is to evaluate the efficacy and safety of Lacutoclax, an oral selective BCL-2 inhibitor, in patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Lacutoclax is a potent and selective BCL-2 inhibitor with relatively weaker inhibitory activity against BCL-XL and BCL-W. Preliminary clinical data have demonstrated promising efficacy and an acceptable safety profile in patients with CLL/SLL and other B-cell non-Hodgkin lymphomas (B-NHLs). This is an open-label, single-arm, multicenter Phase II study evaluating the efficacy and safety of oral Lacutoclax tablets in patients with relapsed or refractory CLL/SLL.

Patients who had previously received standard therapy, experienced disease progression following the most recent line of treatment (excluding intolerance), and had at least one indication for treatment prior to enrollment.
Have at least one measurable lesion.
Age ≥18 years, regardless of sex.
Disqualifiers

Trial design
Single group
Treatments tested in this trial
Lacutoclax
DrugParticipants will first undergo a dose ramp-up period of at least 4 days (Cycle 0: C0D1-C0D4), followed by continuous administration at the target dose of 400 mg once daily starting from Cycle 1. Each treatment cycle will last 28 days. Treatment will continue until disease progression, unacceptable toxicity, or fulfillment of other criteria for treatment discontinuation.
