This phase III trial compares the effect of adding sonrotoclax to zanubrutinib versus zanubrutinib alone for the treatment of patients with untreated chronic lymphoblastic leukemia (CLL)/small lymphocytic lymphoma (SLL). Sonrotoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Zanubrutinib is in a class of medications called kinase inhibitors. It blocks a protein called BTK, which is present on B-cell (a type of white blood cells) cancers such as mantel cell lymphoma at abnormal levels. This may help keep cancer cells from growing and spreading. Giving sonrotoclax and zanubrutinib may be more effective than zanubrutinib alone for the treatment of untreated CLL/SLL.
PRIMARY OBJECTIVES: I. To compare the progression free survival (PFS) between minimal residual disease (MRD)-guided zanubrutinib sonrotoclax therapy to continuous zanubrutinib as control. II. To determine the PFS comparing fixed duration zanubrutinib sonrotoclax therapy to continuous zanubrutinib as control. SECONDARY OBJECTIVES: I. To compare the PFS between the patients with MRD-detectable disease treated with fixed duration zanubrutinib sonrotoclax to the PFS of the patients with MRD detectable disease who receive one additional year of combination therapy. II. To determine the overall…
Inclusion Criteria: * STEP 0: This bone marrow or peripheral blood submission to Adaptive is mandatory prior to registration/randomization for real-time identification of the clone needed for MRD testing. The bone marrow sample should be from the first aspiration (i.e., first pull). Aspirate needle should be redirected if needed to get first pull bone marrow aspirate. It should be obtained as soon after pre-registration as possible to confirm registration eligibility * STEP 0: Patients must be diagnosed with CLL/SLL according to International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2…
