Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the efficacy and safety of BGB-16673 compared with investigator's choice (bendamustine plus rituximab or high-dose methylprednisolone plus rituximab) in participants with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) previously exposed to covalent Bruton tyrosine kinase inhibitor(s) (cBTKi).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic lymphocytic leukemia and small lymphocytic lymphoma are types of blood cancer that affects people around the world. People with CLL and SLL suffer from enlarged lymph nodes, spleen, or liver, or have symptoms like night sweats, weight loss and fever. They have shorter life expectancy compared to healthy people. There is an urgent need for new treatment to prolong life and control disease-related symptoms.

In this study, participants with R/R CLL or SLL who were previously exposed to a covalent BTKi will receive BGB-16673 or the investigator's choice of bendamustine plus rituximab or high-dose methylprednisolone plus rituximab. The main purpose of this study is to compare the length of time that participants live without their CLL or SLL worsening between those participants who receive BGB-16673 versus the investigator's choice of treatment. Approximately 150 participants will be included in this study in Mainland China and Taiwan. Participants will be randomly allocated to receive either BGB-16673 or the investigator's choice of treatment.
