Experimental: Nilotinib |
Drug: Nilotinib
Nilotinib 300 mg is taken by mouth twice a day at 12 hour intervals. Nilotinib is to be taken with water on an empty stomach. No food two hours prior to the dose of nilotinib and for one hour following the dose.

- Log Change From Baseline in Breakpoint Cluster Region Gene (BCR) - Abelson Proto-oncogene (ABL) (Bcr-Abl) Transcript Levels [ Time Frame: From Baseline up to 12 Months ]The change on a logarithmic scale at 12 months from a standardized baseline value (100% on the international scale [IS]) in Bcr-Abl transcripts as assessed by peripheral blood Quantitative real-time polymerase chain reaction (RQ-PCR).
- Number of Participants Who Achieved Major Molecular Response (MMR) [ Time Frame: From Baseline up to 12 Months ]Major Molecular Response (MMR) value at molecular MD is designated a percentage, which is equivalent to a 3-log reduction from a standardized baseline value from the International Randomized InteYesrferon versus STI571 (IRIS) study or 0.1 percent (%) per International Scale (IS).
- Number of Participants Achieved Reduction From a Standardized Baseline Value in Bcr-Abl Transcript Levels up to Month 12 [ Time Frame: From Baseline up to 12 Months ]Number of participants experiencing either a greater than or equal to (>or=) 1, >or= 2, or >or= 3 log10 reduction in Bcr-Abl transcript levels from Baseline to End of Cycle (EOC) 45 (Day1219 - Day1302) were presented.
- Median Time to Best Molecular Response [ Time Frame: From Start of Study up to End of the Study (up to 41 Months) ]The median time to best molecular response, defined as the time (in months) from the date of enrollment to the date when the maximum reduction in Bcr-Abl transcript level was observed.
- Duration of Best Molecular Response [ Time Frame: From Start of Study up to End of the Study (up to 41 Months) ]Duration of best molecular response, defined as the time (in months) from the date of best molecular response to a date when an increase in >1 log10 was observed
- Number of Participants With an Event-free Survival [ Time Frame: From Start of Study up to End of the Study (up to 41 Months) ]Event-free survival was defined as the number of participants from the date of enrollment to the date of first occurrence of any of the following: loss of complete hematological response (CHR), loss of Complete cytogenetic response (CCyR), >1 log increase in Bcr-Abl transcripts from the lowest recorded value, progression to accelerated or blast phase, and death.
- Number of Participants With a Progression-free Survival [ Time Frame: From Start of Study up to End of the Study (up to 41 Months) ]Progression-free survival was defined as the number of participants from the date of enrollment to the date of first occurrence of progression to Accelerated phase (AP) or Blast crisis (BC) phase, chronic myelogenous leukemia (CML) or death. Participants who did not have an event or dropped out without an event are considered censored at the date of the last observed event.
- Number of Participants With an Overall Survival [ Time Frame: From Start of Study Enrollment up to End of the Study (up to 41 Months) ]Overall survival was defined as the number of participants from enrollment to the date of death.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Select Inclusion Criteria:
- Male or female patients ≥ 18 years of age with a confirmed diagnosis of Ph+ CML-CP and CCyR
-
A suboptimal molecular response to imatinib defined as:
- Group 1: Treated with 1 year of imatinib, complete cytogenetic response (CCyR) but no major molecular response (MMR) (Bcr-Abl levels >0.1%IS);
- Group 2: No specific duration of imatinib required, achieved CCyR but has >1 log increase in Bcr-Abl transcript levels
- Adequate end organ function
- Patients must have had an imatinib washout period of at least 3 days and not to exceed 7 days prior to the first dose of nilotinib. Group 1 patients must have been treated with imatinib for at least 1 year. There was no imatinib treatment duration requirement for Group 2 patients.
- For Group 1, patients were eligible for screening if they were treated with an imatinib dose of at least 400mg daily. Dose reduction could have occurred as long as the minimum dose was 300mg daily and the reduction lasted ≤ 28 days. The patient was required to be on 400 mg daily (or a higher dose) of imatinib for at least 6 consecutive months leading up to screening for this study.
- For Group 2 patients, dose reduction while on imatinib could have occurred as long as the minimum dose was 300 mg daily, and the reduction lasted ≤28 days.
Select Exclusion Criteria:
- Prior accelerated phase or blast crisis CML
- Patients achieving prior CCyR on imatinib who lost cytogenetic response prior to entering study
- Previously documented T315I mutations
- Prior therapy with any other tyrosine kinase inhibitor except imatinib
- Patients with contraindications to receiving nilotinib, including concomitant medications
