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 measure the safety, preliminary antitumor activity, pharmacokinetics, and pharmacodynamics with BGB-16673 in combination with other agents in participants with relapsed or refractory (R/R) B-cell malignancies. This study is structured as a master protocol with separate substudies. This study currently includes four substudies, and more substudies may be added as other combination agents are identified.

Detailed Description

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

This new study will check how safe and helpful a potential anticancer drug called BGB-16673 is in participants with R/R B-cell malignancies when it is given in combination with other medicines - sonrotoclax in substudy 1, zanubrutinib in substudy 2, mosunetuzumab in substudy 3, and glofitamab in substudy 4.
