- Conditions
- Interventions
- Registration Number
- NCT06637501
- Lead Sponsor
- BeiGene
- Brief Summary
The purpose of this study is to support the registration plan of sonrotoclax plus zanubrutinib treatment in participants with previously untreated CLL. This study is designed to assess the contribution of sonrotoclax to the efficacy outcome of the combination of zanubrutinib and sonrotoclax.
- Detailed Description
This study will test how effective and safe sonrotoclax plus zanubrutinib treatment compared with zanubrutinib alone in participants with previously untreated chronic lymphocytic leukemia (CLL).

- Arm && Interventions
Group Intervention Description Arm A: Combination Therapy: Sonrotoclax + Zanubrutinib Zanubrutinib Participants will receive sonrotoclax in combination with zanubrutinib daily for a fixed duration of 15 cycles. Arm B: Monotherapy: Zanubrutinib Zanubrutinib Participants will receive zanubrutinib monotherapy daily until disease progression or unacceptable toxicity, whichever occurs first. Arm A: Combination Therapy: Sonrotoclax + Zanubrutinib Sonrotoclax Participants will receive sonrotoclax in combination with zanubrutinib daily for a fixed duration of 15 cycles.
- Primary Outcome Measures
Name Time Method Complete Response (CR)/ Complete Response with Incomplete Bone Marrow Recovery (CRi) Rate Month 16 Best CR/CRi rate per the Independent Review Committee (IRC) response assessment using the 2018 International Workshop on Chronic Lymphocytic Leukemia guidelines with modification for treatment-related lymphocytosis for participants with CLL
- Secondary Outcome Measures
Name Time Method Landmark Duration of Response Event-free Rate at 12 Months 66 months The 12-month landmark duration of response event-free rate is defined as the proportion of responders who remain alive and progression-free at 12 months since the first determination of response.
Undetectable Minimal Residual Disease at < 10^-4Sensitivity (uMRD4) Rate Month 16 uMRD4 rate measured in both peripheral blood and bone marrow aspirate
CR/CRi Rate per Investigator Response Assessment Month 16 CR/CRi Rate (CRR) is defined as the proportion of participants with best overall response of CR or CRi
Overall Response Rate (ORR) per IRC and Investigator Response Assessment Up to 66 Months ORR is defined as the proportion of participants achieving overall response (CR+CRi+partial response \[PR\]+nodular PR) per the IRC and the investigator response assessment.
Duration of Response (DOR) per Investigator Response Assessment Up to 66 Months DOR is defined as the time from the first determination of response until first documentation of progression or death, whichever occurs first
Time to Response (TTR) per IRC and Investigator Response Assessment Up to 66 Months TTR is defined as the time from treatment initiation to the first documentation of response
Landmark Progression-free Survival Rate at 24 Months per Investigator Assessment 24 Months The 24-month landmark PFS rate is defined as the proportion of participants who remain alive and progression-free at 24 months since the start of treatment
Progression-free Survival (PFS) per Investigator Response Assessment Up to 66 Months PFS is defined as the time from the start of treatment to the first documentation of disease progression or death, whichever occurs first
Overall Survival (OS) Up to 66 Months OS is defined as the time from treatment initiation to death due to any cause
Number of Participants with Adverse Events (AEs) From first dose of study drug to 30 days after last dose; up to 66 months for Arm A and Arm B Safety will be assessed by monitoring and recording of all treatment emergent adverse events (AEs) graded by National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0 and the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) grading scale for hematologic toxicities in CLL Studies as appropriate.
