• definition of Imatinib intolerance in CML-CP and AP

  • the patients who discontinued imatinib treatment with any dosage due to Grade 3 or 4 non-hematologic adverse event or Grade 4 hematologic adverse event sustained for more than 7 days even best complementary therapy.

Exclusion Criteria:

• Cardiac dysfunction : LVEF <45% by echocardiography, using pacemaker,Congenital long QT syndrome or a known family history of long QT syndrome, History of or presence of clinically significant ventricular or atrial tachyarrhythmias, Clinically significant resting brachycardia (<50 beats per minute),QTc > 450 msec on baseline ECG (using the QTcF formula), Myocardial infarction within 12 months prior to starting study, Other clinically significant heart disease (e.g. unstable angina, congestive heart failure or uncontrolled hypertension).
• Known cytopathologically confirmed CNS infiltration (in absence of suspicion of CNS involvement, lumbar puncture not required).
• Severe or uncontrolled medical conditions (i.e. uncontrolled diabetes, active or uncontrolled infection).
• History of significant congenital or acquired bleeding disorder unrelated to cancer.

See link for complete list of these medications: http://medicine.iupui.edu/flockhart/table.htm.. Novartis must be contacted if a patient needs to be started on any of these drugs during study treatment.

• patients who diagnosed HIV infection.
• patients who has hypersensitivity for nilotinib or its additives
• Patients who are currently receiving treatment with any medications that have the potential to prolong the QT interval and the treatment cannot be either discontinued or switched to a different medication prior to starting study drug (Please see http://www.torsades.org/medical-pros/drug-lists/printable-drug-list.cfm for a comprehensive list of agents that prolong the QT interval)
• Patients who are: (a) pregnant, (b) breast feeding, (c) of childbearing potential without a negative pregnancy test prior to baseline and (d) male or female of childbearing potential unwilling to use contraceptive precautions throughout the trial
• Patients with rare genetic disease such as galactose intolerance, moderate lactase deficiency or glucose-galactose absorption disorder
