A phase 2, interventional, randomized unblinded study will be conducted in newly diagnosed CP CML patients, to investigate the efficacy and the safety of asciminib at a dose of 80 mg QD as single agent (arm A) or 40 mg BID in combination with nilotinib 300 mg BID (arm B).
All patients in both arm A and arm B will be treated for a minimum of 2 years (core phase). If they will have achieved a DMR (MR4), or if it will be in the interest of the patient, the treatment will be continued.
During the consolidation phase (2 years) asciminib will be continued at the same dose in both arms; in the combination arm the nilotinib dose will be reduced to 300 mg daily.
The patients maintaining a stable MR4 up to the end of the fourth year will discontinue the treatment (TFR phase). The rate of TFR at 5 year (1 year after discontinuation) will be evaluated.

Age ≥ 18 years

Evidence at the time of study entry of typical BCR::ABL1 RNA transcripts e13a2 or e14a2 (b2a2 or b3a2), which are required for BCR::ABL1 international scale reporting
CML in blast phase (BP) or in second chronic phase after previous BP, according to WHO criteria
Previous treatment with TKIs for more than 30 days
Refusal or impossibility to give an informed consent
History or current diagnosis of cardiac disease indicating significant risk of safety for patients participating in the study such as uncontrolled or significant cardiac disease, including any of the following: recent myocardial infarction (within last 6 months), uncontrolled congestive heart failure, unstable angina (within last 6 months), clinically significant (symptomatic) cardiac arrhythmias (e.g., sustained ventricular tachycardia, and clinically significant second or third degree AV block without a pacemaker).
