Chronic lymphocytic leukaemia (CLL) is a slow-progressing cancer that results in uncontrolled proliferation and accumulation of B-lymphocytes in the blood and bone marrow and is the most common form of leukaemia in the western world. CLL patients harbouring a deletion of chromosome 17 (del17p) or the TP53 mutation, who progress after treatment with immunological, chemotherapeutic as well as targeted agents such as ibrutinib have poor prognosis signifying a population with an unmet medical need. Clinical studies showed that venetoclax, a selective; orally bioavailable Bcl-2 inhibitor, induces CLL cell apoptosis, and offers an alternative therapeutic option for CLL, either as a monotherapy or in combination with rituximab. BRAVe was a multicentre, observational retrospective study, conducted in Belgium. The main objectives of this study were to evaluate the safety and effectiveness of venetoclax monotherapy in Belgian patients with CLL, as well as the utilisation of resources in a real life setting. The results show a manageable/favourable safety profile for venetoclax with limited burden for patients and sites, and a good overall response rate in pre-treated CLL patients in the relapsed/refractory setting.
