•Female or male = 18 years of age
•Patients with CML in chronic phase (CP)
•BCR-ABLIS between 0,5-0,01 and demonstrated by the last PCR before inclusion
•not achieving MR4 (defined as < 0,01% BCR-ABLIS) or not achieving a stable MR4 (defined as no continuous in MR4 during the last 12 months before inclusion) after = 3 years of treatment with nilotinib, dasatinib and / or bosutinib in first or second line
•Philadelphia -chromosome and/or BCR-ABL (either b3a2 and /or b2a2) fusion gene positive CML
•Patients must have had an eye examination including fundoscopy by an ophthalmologist within 8 weeks prior to first treatment
Subjects presenting with any of the following criteria will not be included in the trial:
?Failure of any TKI at any time during CML treatment according to current ELN criteria (including any detection of mutations or additional cytogenetic aberrations)
?Prior diagnosis of accelerated phase (AP) or blast phase (BP) at any time in the history of the disease

or > 5 × ULN if leukemic infiltration of the liver is present)
•Positive hepatitis B virus serology test
•No adequate pancreatic function
(serum lipase and amylase >1.5 × ULN)
•No adequate renal function [estimated creatinine clearance (eGFR) of < 50 ml/min, Cockcroft and Gault Score]

?History of
•myocardial infarction (MI)
•clinically significant (as determined by the treating physician) atrial or ventricular arrhythmias
•coronary heart disease
•congenital long QT syndrome or family history of
•use of a ventricular paced pacemaker
•other clinically significant heart disease (e.g. unstable angina, congestive heart failure) or impaired cardiac function
•hyperlipidaemia.
•cerebrovascular accident (CVA, e.g. stroke) or transient ischemic attack (TIA)
•peripheral vascular infarction, including visceral infarction or other vascular occlusive events
•any revascularization procedure, (e.g. placement of stents, bypasses)
•venous thromboembolism, including deep venous thrombosis or pulmonary embolism, within 6 months prior to enrolment
