Acalabrutinib for Chronic Lymphocytic Leukemia with Heart Failure

This study is for people with chronic lymphocytic leukemia (CLL) and heart failure. It compares acalabrutinib (a medication taken by mouth) to treatments chosen by your doctor, which could include chlorambucil, venetoclax, ibrutinib, zanabrutinib, rituximab, or obinutuzumab. The main goal is to see if acalabrutinib causes fewer heart-related side effects that lead to stopping treatment, and how long people stay on treatment before stopping due to heart issues. Researchers will also track serious and fatal heart problems. You may be able to join if you are 18 or older, have CLL, and your heart's pumping ability (Left Ventricular Ejection Fraction or LVEF) is less than 50%. This study is currently unclear on its recruitment status and plans to enroll about 60 participants.

Study design
This is an open-label, randomized study comparing acalabrutinib to other treatments chosen by your doctor. About 60 participants will be enrolled globally.
What's involved
You will have visits every 4 weeks for the first 8 cycles, then every 16 weeks. These visits include physical exams, blood tests, and heart assessments like ECHO, ECG, and Holter monitoring.
Compensation
Not stated in the trial record.
Follow-up
You will be followed for up to 4 years from the last participant joining the study.
