Detailed Description

Observational study to describe the characteristics and outcome of CLL patients treated with venetoclax according to the local label. The study includes two different groups: a retrospective group (all patients who have received at least one dose of venetoclax before enrolment) and a prospective group (patients receiving treatment with venetoclax after enrolment). All patients in both groups will be observed for up to 48 months from the treatment start. In the prospective cohort only, QoL and treatment adherence will be assessed at the time of study entry (i.e. baseline) and thereafter at 3, 6, 9, 12, 18 24, 30, 36, 42 and 48 months of follow-up and at treatment discontinuation (due to any cause).
