Long-Term Follow-Up in Patients With Chronic Myeloid Leukemia Treated With Ponatinib in a Real-World Cohort: Safety and Efficacy Analysis.

Background: Ponatinib is a third-generation tyrosine-kinase inhibitor (TKI), indicated in patients with chronic phase (CP), accelerated phase (AP), or blast phase (BP) chronic myeloid leukemia (CML), who are resistant or intolerant to ≥2 prior TKIs, patients for whom subsequent treatment with imatinib is not appropriate, and patients who have a T315I mutation.

Patients And Methods: We aimed to evaluate outcomes of ponatinib treatment, including safety, with focus on cardiovascular toxicity, in real-world patients from Argentina. Data from patients with CP CML treated with ponatinib was retrospectively retrieved from 2013 to 2023 in 7 centers.
