Lead Sponsor

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).

The main goals of the study are to determine how many participants may no longer have evidence of cancer or have some improvement in the signs and symptoms of cancer after treatment and to determine what adverse events, or side effects, patients might experience.

Sonrotoclax is an experimental drug that works by blocking a protein called B-cell lymphoma-2 (Bcl-2). This protein helps certain types of blood tumor cells to survive and grow. When sonrotoclax blocks Bcl-2 it slows down or stops the growth of tumor cells and helps them die. This can lead to improvements in patients with CLL disease.

Zanubrutinib is a commercialized product that works by blocking a protein called Bruton's tyrosine kinase (BTK) and controlling the activity and survival of malignant B cells. Zanubrutinib has received approval in over 65 countries/regions worldwide for the treatment of adult participants with B cell malignancies, including CLL.

The study will enroll approximately 87 participants who will be randomly assigned by a computer program to receive one of the following treatments: sonrotoclax + zanubrutinib or zanubrutinib.

The study will take place at multiple centers worldwide. The overall time to participate in this study is approximately 5 years.

Primary Outcome Measures
NameTimeMethod
Complete Response (CR)/ Complete Response with Incomplete Bone Marrow Recovery (CRi) RateMonth 16

Secondary Outcome Measures
NameTimeMethod
Landmark Duration of Response Event-free Rate at 12 Months66 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) RateMonth 16

uMRD4 rate measured in both peripheral blood and bone marrow aspirate

CR/CRi Rate per Investigator Response AssessmentMonth 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 AssessmentUp 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 AssessmentUp 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 AssessmentUp 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 Assessment24 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 AssessmentUp 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.
