Safety and efficacy of asciminib treatment in chronic myeloid leukemia patients in real-life clinical practice.

Abstract

Despite the excellent overall survival (OS) of chronic myeloid leukemia (CML) patients, a significant proportion will fail currently available tyrosine-kinase inhibitors (TKIs) due to resistance or intolerance. Intolerant patients are usually managed successfully with alternative second-generation tyrosine-kinase inhibitors (2GTKIs). However, more than half of the patients will eventually discontinue second-line treatment due to loss of response or toxicity. Ponatinib is an effective drug in the setting of resistance to 2GTKIs, however with life-threatening side effects and varying responses.
