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 or chlorambucil plus obinutuzumab) 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).
Phase 3 trials are pivotal studies with large patient populations (hundreds to thousands) designed to prove efficacy and safety for FDA submission. A successful Phase 3 readout is typically the last major hurdle before a New Drug Application (NDA) or BLA filing.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
BeiGene Ltd (BGNE) is the sponsoring company for this trial. BiotechSign currently grades this company C (63/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
