PICAROS - Acalabrutinib RWE on 1L CLL in Spain

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).
