Observational Study on Venetoclax Treatment for Adults with Chronic Lymphocytic Leukemia CLL in Austria, Germany, and Switzerland

What this Trial Is About

Researchers are observing adults with Chronic Lymphocytic Leukemia CLL who are receiving the drug venetoclax, either alone or combined with other medications such as rituximab, obinutuzumab, ibrutinib, or acalabrutinib. The study aims to understand how these treatments work in real-life settings, focusing on the effectiveness, costs related to health economics, and outcomes reported by the patients themselves. Participants receive venetoclax as prescribed by their doctors following local medical guidelines. They may receive it alone or alongside one of the other drugs mentioned. This study does not assign treatments but observes patients as they undergo therapy according to routine clinical practice across several countries. During the study, participants are monitored for their response to treatment, with the main focus on the best overall response rate within 12 months. Researchers collect data on health outcomes, costs, and patient experiences to better understand the impact of these therapies. The study spans several years, allowing long-term observation of treatment effects and outcomes.
