NCT ID NCT04419519

First seen Nov 19, 2025 · Last updated May 08, 2026 · Updated 23 times

Summary

This study looks at whether people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have very low levels of cancer cells (called MRD-negative) after taking venetoclax can stop the drug and stay healthy for at least a year. About 81 adults who are already on or about to start venetoclax (alone or with another drug) will be followed to see how long they can remain off treatment without their cancer coming back. The goal is to reduce side effects and medication burden while keeping the disease under control.
