Summary

This observational study follows 321 Italian patients with relapsed or refractory chronic lymphocytic leukemia (CLL) who are treated with venetoclax-based regimens outside of clinical trials. The goal is to describe their clinical features and outcomes, such as how long they live without the disease worsening. By collecting real-world data from March 2016 to June 2025, researchers hope to better understand the effectiveness and safety of venetoclax in routine care.

Active substance
Venetoclax
What this could lead to
If successful, this study could provide real-world evidence on how well venetoclax works for CLL patients outside of clinical trials, potentially guiding better treatment decisions.
What could go wrong
This is an observational study, not a controlled trial, so results may be influenced by patient selection and other factors. It does not test a new treatment but observes existing ones.
