clinically relevant diabetic complications such as neuropathy, retinopathy, nephropathy,
coronary or peripheral vascular disease.
8. History of active malignancy during the past 5 years with the exception of basal carcinoma of the skin or carcinoma in situ of cervix uteri or breast.
9. Acute liver disease or cirrhosis.
10. Previous or active acute or chronic pancreatic disease.
11. Another severe and/or life threatening medical disease.
12. History of significant congenital or acquired bleeding disorder unrelated to cancer.
13. Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drug.
14. Patients actively receiving therapy with strong CYP3A4 inhibitors and the treatment cannot be either discontinued or switched to a different medication prior to starting study drug.
15. 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.
16. Patients who are:
a) pregnant.
b) breast feeding.
c) of childbearing potential without a negative pregnancy test prior to baseline.
d) male or female of childbearing potential unwilling to use contraceptive precautions throughout the trial (post menopausal women must be amenorrheic for at least 12 months to be considered of non childbearing potential).
17. Interruption of imatinib therapy for a cumulative period in excess of 21 days in the preceding 3 months.
18. Major toxicity on imatinib in past 3 months.
19. History of non compliance, or other inability to grant informed consent.
20. Past or present history of alcohol abuse, use of illicit drugs, or severe psychiatric disorders, including depression.
21. Known hypersensitivity to any interferon preparation
22. Autoimmune hepatitis or a history of autoimmune disease
23. Pre existing thyroid disease unless it can be controlled with conventional treatment
24. Epilepsy and/or compromised central nervous system (CNS) fun

Primary Outcome(s)

Secondary Objective: To assess:
• the safety and tolerability of nilotinib alone or in combination with PegIFN.
• the duration of response
•the percentage of patients who lose response after cessation of IFN between Month 12 and 18
• the adherence to combination treatment
• disease progression
• overall survival
• quality of life.
- To compare safety and efficacy data with those from nilotinib treated patients in the ENESTcmr study.
- To perform immunological and other laboratory studies to explain effects and toxicity.
- To identify biomarkers for response.

Main Objective: To assess the effect of switching CML patients, who have been treated with imatinib =2 years and who have stable detectable molecular residual disease above 0.01% (IS), to the combination of Nilotinib and PegIFN, in terms of the proportion of patients who achieve confirmed MR4.0.

Primary end point(s): The proportion of patients with confirmed MR4.0 IS at Month 12 .

Timepoint(s) of evaluation of this end point: A safety interim analysis by a Safety Monitoring Committee (SMC) is planned after 15 patients have completed the Month 6 study assessment, i.e. after 3 months of the combination therapy. The SMC will consist of three experienced hematologists. They will make a recommendation as to whether the study should continue, stop or be modified based on its findings. The SMC recommendation will be notified to the principal investigator verbally and in written form as soon as possible after the meeting.

Secondary Outcome(s)

Secondary end point(s): • Safety and tolerability, including frequency and type of AEs/serious AEs.
• The proportion of patients with MR4.0 and with MR4.5 IS at or by Month 3, 6, 12, 18 and 24.
• The proportion of patients who complete the planned 9 months of combination therapy with PegIFN (i.e. to Month 12 assessment).
• The rate of loss of CCyR, MMR and MR4.0 at Month 12, 18.
• The proportion of patients progressing to advanced disease phase.
• Overall survival.
• Quality of Life as assessed by standard questionaires
• ECOG performance rating at baseline, month 3, 6, 12 and 18.

Timepoint(s) of evaluation of this end point: A safety interim analysis by a Safety Monitoring Committee (SMC) is planned after 15 patients have completed the Month 6 study assessment, i.e. after 3 months of the combination therapy.

The study should be stopped if 4 out of 5, 6 out of 10 or 8 out of 15 patients experience grade 4 hematological toxicity, or grade 3 non hematological toxicity after 3 months of PegIFN treatment.

An evaluation of the dose increase from 25 to 40 µg/week will be performed when 15 patients have passed the 9 month time point (i.e 3 months on 40 µg/week).
