Known second chronic phase of CML after previous progression to AP/BC
Poorly controlled diabetes mellitus (defined as HbA1c > 9%)
Impaired cardiac function including any one of the following:
LVEF < 45% or below the institutional lower limit of the normal range (whichever is higher)
Inability to determine the QT interval on ECG, except for patients with evidence of measurable QT interval at the time of CML diagnosis (e.g. prior to first start of TKI treatment) and who have no documented clinical signs of cardiovascular disease and/or clinical signs of conduction abnormality.

Use of a ventricular-paced 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 bradycardia
QTc > 450 msec on the average of three serial baseline ECG (using the QTcF formula). If QTcF > 450 msec and electrolytes are not within normal ranges, electrolytes should be corrected and then the patient re-tested for QTc.This exclusion criterion is not applicable for patients with non-measurable QT interval who have evidence of measurable QT interval at the time of CML diagnosis (e.g. prior to first start of TKI treatment) and who have no documented clinical signs of cardiovascular disease and/or clinical signs of conduction abnormality.
History or clinical signs of myocardial infarction within 1 year of study entry
History of unstable angina within 1 year of study entry
Other clinically significant heart disease (e.g. congestive heart failure, cardiomyopathy or uncontrolled hypertension)
History of acute pancreatitis within 1 year of study entry or past medical history of chronic pancreatitis
Known presence of significant congenital or acquired bleeding disorder unrelated to cancer
History of another active malignancy within 5 years prior to study entry with the exception of previous or concomitant basal cell skin cancer and previous carcinoma in situ treated curatively
Treatment with other investigational agents (defined as not used in accordance with the approved indication) within 4 weeks of Day 1
Patients actively receiving therapy with strong CYP3A4 inhibitors and/or inducers, and the treatment cannot be either discontinued or switched to a different medication prior to starting study drug. See Appendix 1 for a list of these medications. This list may not be exhaustive.
Patients actively receiving therapy with herbal medicines that are strong CYP3A4 inhibitors and/or inducers, and the treatment cannot be either discontinued or switched to a different medication prior to starting study drug. These herbal medicines may include Echinacea, (including E. purpurea, E. angustifolia and E. pallida), Piperine, Artemisinin, St. John's Wort, and Ginkgo.
Patients who are currently receiving treatment with any medications that have the potential to prolong the QT interval and the treatment cannot be either safely 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 list of agents that prolong the QT interval)
Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drug (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, small bowel resection, or gastric bypass surgery)
Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during the study and for 14 days after the final dose of nilotinib. Highly effective contraception is defined as either:
Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
Male sterilization (at least 6 months prior to enrolling). For female patients on the study the vasectomized male partner should be the sole partner for that patient.
Use of a combination of any two of the following:
Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception.
Placement of an intrauterine device (IUD) or intrauterine system (IUS)
Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks prior to enrolling. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
If a study patient becomes pregnant or suspects being pregnant during the study or within 30 days after the final dose of nilotinib, the Study Doctor needs to be informed immediately and ongoing study treatment with nilotinib has to be stopped immediately.
Other protocol-defined inclusion/exclusion criteria may apply.
