A Study to Investigate Sonrotoclax (BGB-11417) Plus Zanubrutinib (BGB-3111) Compared With Venetoclax Plus Acalabrutinib in Adults With Previously Untreated Chronic Lymphocytic Leukemia
What this study is about
The purpose of this study is to investigate the effectiveness and safety of fixed-duration sonrotoclax (also known as BGB-11417) plus zanubrutinib (also known as BGB-3111) (SZ) compared with fixed-duration of venetoclax plus acalabrutinib (AV) in participants with previously untreated chronic lymphocytic leukemia (CLL).

The purpose of this study is to investigate the efficacy and safety of fixed-duration sonrotoclax (also known as BGB-11417) plus zanubrutinib (also known as BGB-3111) (SZ) compared with fixed-duration of venetoclax plus acalabrutinib (AV) in participants with previously untreated chronic lymphocytic leukemia (CLL).
Interventions
DRUG
Sonrotoclax
Administered orally.
DRUG
Zanubrutinib
Administered orally.
DRUG
Acalabrutinib
Administered orally.
DRUG
Venetoclax
Administered orally.
Primary outcome measures
Progression-Free Survival (PFS) as Determined by Independent Review Committee (IRC)
Time frame: Up to approximately 70 months
PFS is defined as the time from the date of randomization to the date of disease progression as determined by IRC or death due to any cause, whichever occurs first.
Rate of Undetectable Minimal Residual Disease at < 10^-4 sensitivity (uMRD4)
Time frame: Up to approximately 16 months
Rate of uMRD4 is defined as the percentage of participants that achieved uMRD4 measured in both peripheral blood (PB) and bone marrow aspirate (BMA) at the post-treatment follow-up visit (PTFU1) based on next generation sequencing (NGS).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
