Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma | Drug: Zanubrutinib Drug: Ibrutinib | Phase 3 |
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.
