This study is designed to compare the overall response rate of zanubrutinib versus ibrutinib in participants with relapsed/refractory chronic lymphocytic leukemia or small lymphocytic lymphoma.
A Phase 3, Randomized Study of Zanubrutinib (BGB-3111) Compared With Ibrutinib in Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma
This is a global, Phase 3, randomized study of zanubrutinib versus ibrutinib in approximately 600 participants with relapsed/refractory chronic lymphocytic leukemia or small lymphocytic lymphoma. The primary efficacy endpoint is overall response rate determined by investigator assessment. Participants will be randomized in a 1:1 manner to either zanubrutinib or ibrutinib. Treatment with zanubrutinib and ibrutinib will be open label.
