The purpose of this study is to test the safety and tolerability of an experimental anticancer drug currently known as BGB-16673 for men and women who have B-cell malignancies.
Experimental means that it has not yet been approved by the US Food and Drug Administration (FDA).
BGB-16673 is an oral Bruton tyrosine kinase (BTK) targeted protein degrader, which targets and binds to BTK in the body, inhibiting its activity. BTK in the body allows malignant cells to survive and BTK inhibitors interfere with this process.
