Observational Cohort Study of Chronic Lymphocytic Leukaemia Patients Treated With Acalabrutinib in the UK Early Access Programme

What this Trial Is About

Researchers are studying patients with chronic lymphocytic leukaemia CLL who have been treated with acalabrutinib in the United Kingdom. This observational study aims to describe the characteristics and real-world clinical outcomes of these patients, especially those who started acalabrutinib treatment as part of the UK Early Access Programme. The study seeks to provide UK-specific data on how patients respond to and tolerate acalabrutinib in typical clinical settings. The study involves reviewing clinical records of treatment-naefve CLL patients who began acalabrutinib between April 1, 2020, and April 1, 2021. The focus is on patients treated in the first-line setting with acalabrutinib under the Early Access Programme. This non-interventional study does not involve new treatments but collects and analyzes existing data to estimate progression-free survival, overall survival, response rates, treatment patterns, and healthcare resource use. Participants medical information will be gathered from their clinical records following local laws. Researchers will track outcomes such as progression-free survival at various time points up to 60 months, overall survival, response rates, and treatment interruptions. The study design allows for long-term observation of how patients fare with acalabrutinib, providing valuable real-world evidence. The study is expected to continue through April 2027.
