Patients must have an imatinib washout period of at least 3 days and not to exceed 7 days prior to the first dose of nilotinib. 13. Ability to provide written informed consent prior to any study related screening procedures being done
Exclusion criteria:
- Patients who have experienced any Grade 3 or higher non-hematologic toxicity 30 days prior to screening
- Loss of response (hematologic, cytogenetic, molecular) any time prior to inclusion
- Prior accelerated phase or blast phase CML

Impaired cardiac function including any of the following:
- LVEF < 45% as determined by echocardiogram reading or MUGA
- Complete left bundle branch block
- Long QT syndrome or a known family history of long QT syndrome
- History or presence of clinically significant ventricular or atrial tachyarrhythmias
- Clinically significant resting bradycardia (< 50 beats per minute)
- QTcF > 450 msec on baseline ECG. If QTcF > 450 and electrolytes are not within normal ranges, electrolytes were to be corrected and then the patient re-screened for QTcF
- Myocardial infarction within 1 year of starting study drug
Other clinically significant heart disease (e.g., unstable angina, congestive heart failure, or uncontrolled hypertension) 9. Patients receiving therapy with inhibitors of CYP3A4 or medications that prolong the QT interval and cannot be either discontinued or switched to a different medication prior to starting study drug. 10. Treatment with strong CYP3A4 inducers (e.g. phenytoin, carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, St. John's Wort), that cannot be discontinued or switched to a different medication prior to starting study drug. 11. Impaired gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drug. 12. History of acute pancreatitis within 1 year of study entry. 13. Known cytopathologically confirmed CNS infiltration (in absence of suspicion of CNS involvement, lumbar puncture not required). 14. Any other malignancy that is clinically significant or requires active intervention.
15. Severe or uncontrolled medical conditions (i.e., uncontrolled diabetes, active or uncontrolled infection). 16. Acute or chronic liver or severe renal disease considered unrelated to cancer.
17. History of significant congenital or acquired bleeding disorder unrelated to cancer.
18. Previous radiotherapy to ≥ 25% of the bone marrow. 19. Major surgery within 4 weeks prior to Day 1 of study or patients who have not recovered from prior surgery. 20. Treatment with other investigational agents within 30 days of Day 1. 21. History of non-compliance to medical regimens or inability to grant consent 22. Women who are pregnant, breast feeding, or of childbearing potential without a negative urinary test at baseline

Periodo de tiempo |
---|---|---|
Number of Participants With Improvement of Grades of Persistent Non-hematological Adverse Event (AE) for Grade 1 and 2 at 6 Months
Periodo de tiempo: at 6 month after switching from imatinib to nilotinib
|
Improvement was defined as decreasing of grade of non-hematological toxicity from 2 to <2 or from 1 to <1.
In case of multiple low-grade non-hematological toxicities improvement was defined as an improvement of at least one non-hematological AE and no worsening of any other persistent non-hematological AEs.

Periodo de tiempo: at 3 month after switching from imatinib to nilotinib
|
Improvement was defined as decreasing of grade of non-hematological toxicity from 2 to <2 or from 1 to <1.
