Brief Summary: The purpose of this open-label, single-arm study is to evaluate the impact of venetoclax on the quality of life of participants with chronic lymphocytic leukemia (CLL; a type of cancer affecting the blood and the bone marrow) including those with the 17p deletion or TP53 mutation (local lab assessed) OR in CLL participants who have received prior B-Cell Receptor Inhibitor (BCRi) therapy. The starting dose of venetoclax is 20 mg once daily. The dose must be gradually increased over a period of 5 weeks up to the daily dose of 400 mg.
