Observational Study of Acalabrutinib in Patients With Chronic Lymphocytic Leukaemia in the United Kingdom
- Registration Number
- NCT05557695
- Lead Sponsor
- AstraZeneca
- Brief Summary
This is a retrospective observational research study to describe the characteristics and real-world clinical outcomes of patients with chronic lymphocytic leukaemia receiving acalabrutinib in the United Kingdom (the EPIC study). Physicians treating chronic lymphocytic leukaemia patients with acalabrutinib, where the patients started treatment as part of the acalabrutinib Early Access Programme (EAP), will be invited to recruit patients. Clinical data will be extracted from the patients' clinical records in line with local laws. Data from this study will provide UK-specific real-world data on patients who were started on acalabrutinib as part of the UK acalabrutinib EAP.
- Detailed Description
1. Primary Objectives:
a. To estimate real-world progression-free survival in patients with CLL who received acalabrutinib in the first-line.
2. Secondary Objectives:
1. To estimate real-world overall survival in patients with CLL who received acalabrutinib in the first-line.
2. To describe real-world response rate to acalabrutinib in patients with CLL who received acalabrutinib in the first-line.
3. To describe the healthcare resource utilisation in patients with CLL who received acalabrutinib in the first-line.
4. To describe post-progression treatment patterns in patients with CLL who progressed from first-line acalabrutinib.
5. To describe real-world clinical progression free survival in patients with CLL who received acalabrutinib in the first-line and progressed during acalabrutinib treatment.
6. To describe acalabrutinib treatment patterns in patients with CLL who received acalabrutinib in the first-line.
7. To describe baseline clinical and demographic characteristics in patients with CLL who received acalabrutinib in the first-line.

Group Intervention Description Group 1 Acalabrutinib Patients with chronic lymphocytic leukaemia treated with acalabrutinib in first line
- Primary Outcome Measures
Name Time Method Real-world progression free survival (rwPFS) 60 months rwPFS will be defined as the time from index date until earliest record of real-world progression event as determined by physicians' assessment, or death (if no progression) or end of follow-up (for censored observations) whilst on first line treatment.
- Secondary Outcome Measures
Name Time Method Real-world response rate (rwRR) 60 months rwRR will be defined as the proportion of patients with a recorded significant anti-cancer response and will be defined here as the sum of complete response, partial response and partial response + lymphocytosis. Response will be based on the on the documented assessment of the local investigator.
Real-world overall survival (rwOS) 60 months rwOS will be defined as the time from index date up to death or last date the patient was known to be alive (for censored observations).
Frequency of acalabrutinib dose interruptions Through study completion, an average of 5 years A treatment interruption will be defined as clinician or patient-initiated temporary treatment cessation of acalabrutinib, where treatment is known to have been recommenced at any time within the observation window (without initiation on a different systemic treatment for CLL in the intervening period).
Real-world clinical progression free survival 2 (rwPFS2) 60 months rwPFS2 will be defined as the time from index date to the date of the second record of real-world progression (as determined by physicians' assessment) or death due to any cause (if no progression), whichever occurs first whilst on second line treatment. If there is no second progression or the patient is lost to follow-up, PFS2 will be censored at the time of the last available tumour assessment.
