Safety and efficacy of asciminib treatment in chronic myeloid leukemia patients in real-life clinical practice
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. Asciminib is a first-in-class STAMP (Specifically Targeting the ABL Myristoyl Pocket) inhibitor that potently and specifically inhibits BCR-ABL1 via binding to a pocket distinct from the ATP binding site of the kinase. Asciminib has the potential to overcome resistance to prior TKIs, and also offers the possibility of dual inhibition of BCR-ABL1 in combination with ATP-binding TKIs. Asciminib has been evaluated in a phase I study in patients with Ph-positive leukemia failing prior TKIs, with promising results. Our aim is to share the first data on the use of asciminib in CML patients in clinical practice, allowed by Novartis under a managed-access program (MAP).
