Efficacy of Asciminib in Real-world in Patients With Chronic Myeloid Leukemia in Second or Subsequent Lines

Overview

The goal of this observational study is to evaluate the efficacy and tolerability of asciminib in real-life in patients with chronic myeloid leukemia treated in second or subsequent lines. The main object of the study is to assess the achievement of Major Molecular Response.

ASCIRLI is an observational, multicenter, retrospective and prospective study designed to include all adult patients with chronic-phase chronic myeloid leukemia (CML-CP) who initiated second-line or subsequent lines of therapy with asciminib after the date of its commercial availability. In detail, treatment with asciminib in third or greater line was approved in July 2023, while treatment in the other lines of therapy was approved in December 2025. Patients will be included according to these timelines. The study aims to generate comprehensive real-world evidence on the effectiveness, safety, tolerability, and health-related quality of life (HRQoL) associated with asciminib use in routine clinical practice, complementing data derived from controlled clinical trials and reflecting treatment patterns, patient characteristics, and outcomes observed in an unselected population. Treatment with asciminib will be independent from participation to this observational study and must not be initiated for the purpose of participating to this study. Clinical data at the time of enrollment will be collected, together with previous history of resistance and/or intolerance to previous lines of treatment, including type of adverse events and mutations. Cytogenetic (eventually) and molecular responses will be collected at 3, 6,12 and subsequent follow-up according to ELN criteria. Discontinuation and dose adjustments will be recorded. Patients will be followed according to the routine medical practice expected at least every 3-6 months. The recruitment period is planned for 24 months from the first patient included, observation period for 36 months, with a total study duration of 60 months.
