A Phase 3, Open-Label, Randomized Study of Sonrotoclax (BGB-11417) Plus Zanubrutinib (BGB-3111) Compared With Venetoclax Plus Acalabrutinib in Patients With Previously Untreated Chronic Lymphocytic Leukemia
Summary

Outcome measures
Primary
Progression-Free Survival (PFS) as Determined by Independent Review Committee (IRC)
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.
Time frame: Up to approximately 70 months
Rate of Undetectable Minimal Residual Disease at < 10^-4 sensitivity (uMRD4)
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).
Time frame: Up to approximately 16 months
Secondary
PFS in High-Risk Participants
Time frame: Up to approximately 70 months
Overall Survival (OS)
Time frame: Up to approximately 70 months
Overall Response Rate (ORR) as Determined by IRC
Time frame: Up to approximately 70 months
Rate of Undetectable Minimal Residual Disease at < 10^-5 sensitivity (uMRD5)
Time frame: Up to approximately 16 months
