CLL / SLL

The goal of this clinical trial is to learn if zanubrutinib induction followed by delayed fixed-duration combination with sonrotoclax works to treat previously untreated Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL). It will also learn about the safety of this combination regimen. The main questions it aims to answer are:Does this combination therapy achieve undetectable minimal residual disease (uMRD) in participants?What medical problems (adverse events) do participants have when taking zanubrutinib and sonrotoclax?Researchers will conduct a single-arm study to systematically evaluate the MRD clearance, efficacy, safety, and immune-related functions of this specific treatment sequence.Participants will:Low-risk group (without 17p deletion/TP53 mutation): Take zanubrutinib monotherapy for 12 cycles, followed by combination zanubrutinib + sonrotoclax for 12 cycles, then discontinue treatment for observation.High-risk group (with 17p deletion/TP53 mutation): Follow the same initial regimen (12 cycles monotherapy + 12 cycles combination), followed by zanubrutinib monotherapy maintenance until disease progression.Visit the clinic periodically for MRD assessment (via flow cytometry), efficacy evaluation (CT/PET-CT, lab tests), and safety checks (physical exam, blood tests, ECG).Undergo immune function evaluation via peripheral blood samples to assess changes in T-cell counts and subsets.

This is a Phase 3, randomized, open-label, multicenter study comparing rocbrutinib (LP-168) versus pirtobrutinib in adult participants with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have previously received a covalent Bruton's tyrosine kinase inhibitor (cBTKi). Approximately 306 participants will be randomized 1:1 to receive rocbrutinib 200 mg orally once daily or pirtobrutinib 200 mg orally once daily, administered continuously in 28-day cycles until disease progression, unacceptable toxicity, withdrawal of consent, or other discontinuation criteria are met. Randomization will be stratified by presence of del(17p)/TP53 mutation (yes/no), reason for discontinuation of prior cBTKi therapy (toxicity vs disease progression), prior exposure to a BCL2 inhibitor (yes/no), and region (United States/China/rest of world). The primary endpoint is progression-free survival (PFS) assessed by an independent review committee (IRC) using iwCLL 2018 criteria for CLL and Lugano 2014 criteria for SLL. Key secondary objectives include overall survival, overall response rate, time-to-event outcomes, and safety/tolerability; exploratory objectives include health-related quality of life and biomarker assessments.

This is a multicenter, prospective, single-arm phase II study designed to evaluate the safety and efficacy of lisaftoclax (APG-2575), an oral selective BCL-2 inhibitor, in patients with indolent B-cell lymphomas. The study will enroll adult patients with chronic lymphocytic leukemia (CLL), Waldenström macroglobulinemia (WM), or marginal zone lymphoma (MZL) who are either treatment-naïve but considered ineligible for Bruton tyrosine kinase (BTK) inhibitor therapy due to significant comorbidities, or who are intolerant to prior BTK inhibitor treatment. Eligible patients will receive oral lisaftoclax once daily with a dose ramp-up to a target dose of 600 mg in 28-day cycles. Treatment will continue until disease progression, unacceptable toxicity, withdrawal of consent, or completion of the planned treatment period. The primary objective is to evaluate the safety and tolerability of lisaftoclax monotherapy, while secondary objectives include assessment of antitumor activity, including overall response rate (ORR), complete response (CR) rate, minimal residual disease (MRD) negativity, progression-free survival (PFS), duration of response (DOR), and overall survival (OS). Quality of life will also be assessed using the EORTC QLQ-C30 questionnaire.

This is a clinical study aiming to evaluate the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of ZE50-0134 in relapsed and refractory chronic lymphocytic leukemia, small lymphocytic lymphoma, and select low-grad lymphomas.
