A Study to Investigate Safety and Effectiveness of BGB-16673 in Combination With Other Agents in Participants With Relapsed or Refractory B-Cell Malignancies

Purpose

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.

Conditions

B-cell Malignancy
Relapsed Cancer
Refractory Cancer
B-cell Lymphoma

Eligibility

Eligible Ages: Over 18 Years
Eligible Genders: All
Accepts Healthy Volunteers: No

Detailed Description

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.
