About this study

This phase II trial studies how well acalabrutinib and venetoclax with or without early obinutuzumab work for the treatment of chronic lymphocytic leukemia or small lymphocytic lymphoma that is high risk, has come back (recurrent), or does not respond to treatment (refractory). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Venetoclax may stop the growth cancer cells by blocking BCL-2 protein needed for cell growth. 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. Giving acalabrutinib and venetoclax together with early obinutuzumab may improve clinical outcomes and control the disease.
