PICAROS - Acalabrutinib RWE on 1L CLL in Spain

Condition(s) studied

Study summary

This is a multicenter non-interventional study (NIS) of patients with CLL treated with first-line acalabrutinib according to routine clinical practice in Spain. It included an initial cohort of patients who initiated treat-to-progression acalabrutinib for the first time within the year before the first site initiation visit, both for previously untreated CLL and after switching in first line from another BTK inhibitor due to intolerance in absence of progression (cohort 1). This cohort is complemented with the addition of another regarding the first-line fixed-duration acalabrutinib use with venetoclax in routine practice (cohort 2).

Eligibility

Primary outcome measure(s)

• Proportion of patients on acalabrutinib therapy at 24 months after treatment initiation (cohort 1). — 24 months after treatment initiation (cohort 1).
  Proportion of patients on acalabrutinib therapy at 24 months after treatment initiation (cohort 1). In addition to this outcome measured in the overall cohort, it will also be assessed by the following factors: 1. the reason for treatment initiation (i.e., first-line treatment-naïve patients, and those switching due to intolerance in absence of progression), 2. presence/absence of risk factors (i.e., del17p, TP53 mutation, and unmutated IGHV). 3. cardiovascular comorbidities (yes/no).
• Real-world overall response rate (rwORR) achieved until the end of the observational period for first-line fixed duration acalabrutinib therapy (cohort 2) — From fixed-duration acalabrutinib start to the start date of a subsequent line therapy or study end date (cohort 2), assessed up to 25 months after the inclusion of the last patient in the cohort 2.
  rwORR (i.e., the proportion of patients that achieved complete or partial response) achieved until the end of the observational period for first-line fixed-duration acalabrutinib therapy as assessed by the treating physician (cohort 2). Complete response may include complete response, complete response with incomplete marrow recovery, or unconfirmed complete response (marrow biopsy not performed). Partial response may include partial response, or partial response with lymphocytosis. The rwORR will be assessed by the treating physician in routine clinical practice, including the use or not of the 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria. The end of observational period for first-line fixed-duration combinations of acalabrutinib is defined as the start date of a subsequent line therapy or study end date, whichever comes first.
