How does venetoclax work for CLL patients in everyday clinics?

NCT ID NCT03342144

First seen Jun 25, 2026 · Last updated Aug 14, 2026 · Updated 4 times

Summary

This study is tracking 500 people with chronic lymphocytic leukemia (CLL) who are taking venetoclax, either alone or with other drugs, as part of their normal care in Austria, Germany, and Switzerland. Researchers want to see how well the treatment works in real-life settings and what costs are involved. The study does not assign treatments—doctors prescribe based on local guidelines.
