Randomized, Phase III Study of Early Intervention With Venetoclax and Obinutuzumab Versus Delayed Therapy With Venetoclax and Obinutuzumab in Newly Diagnosed Asymptomatic High-Risk Patients With Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma (CLL/SLL): EVOLVE CLL/SLL Study
National Cancer Institute (NCI)
Summary
This phase III trial compares early treatment with venetoclax and obinutuzumab versus delayed treatment with venetoclax and obinutuzumab in patients with newly diagnosed high-risk chronic lymphocytic leukemia or small lymphocytic lymphoma. Venetoclax 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. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Starting treatment with the venetoclax and obinutuzumab early (before patients have symptoms) may have better outcomes for patients with chronic lymphocytic leukemia or small lymphocytic lymphoma compared to starting treatment with the venetoclax and obinutuzumab after patients show symptoms.
Description
PRIMARY OBJECTIVE: I. To evaluate whether early treatment with venetoclax and obinutuzumab (V-O) extends overall survival (OS) compared with delayed treatment with V-O in high-risk (Chronic Lymphocytic Leukemia \[CLL\] International Prognostic Indicator \[CLL-IPI\] \>= 4 or complex cytogenetics), newly diagnosed asymptomatic CLL/small lymphocytic lymphoma (SLL) participants. SECONDARY OBJECTIVES: I. To compare overall response rates (complete response \[CR\] + complete response with incomplete marrow recovery \[CRi\] + partial response \[PR\]), CR rates, progression-free survival (PFS), and…
