A Phase 3, Open-Label, Randomized Study to Evaluate the Safety and Efficacy of BGB-16673 Compared to Pirtobrutinib in Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma
The purpose of this study is to evaluate the efficacy and safety of BGB-16673 alone compared with pirtobrutinib in patients with relapsed or refractory (R/R) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who had been previously treated with a covalent Bruton tyrosine kinase inhibitor (cBTKi).
• Confirmed diagnosis of CLL or SLL, requiring treatment, based on 2018 iwCLL criteria
• Previously received treatment for CLL/SLL with a covalent Bruton tyrosine kinase inhibitor (cBTKi). Patients should have disease relapsed after or refractory to at least 1 line of therapy including a cBTKi.
• Participants with SLL must have measurable disease by computed tomography/magnetic resonance imaging, defined as ≥ 1 lymph node \> 1.5 cm in longest diameter and measurable in 2 perpendicular diameters.
