Experimental: Nilotinib
Nilotinib was administered orally at 300 mg BD at approximately 12 hour intervals which had to be taken without food.
The capsules were to be swallowed whole with water and no food should have been consumed for at least 2 hours before and at least 1 hour after the dose was taken.
Prior to the first dose of nilotinib, patients were required to have an imatinib or dasatinib washout period of at least 3 days.
Therapy with nilotinib was to be continued for up to 24 months while on study.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Deep Molecular Response (MR4.5) Rate: Percentage of Patients Who Have Achieved a 4.5-log Reduction in BCR-ABL Level Within 24 Month
Time Frame: Baseline, 96 weeks (24 months)
|
Deep Molecular Response (MR4.5) rate is defined as the percentage of patients who have achieved a 4.5 -log reduction in Breakpoint cluster region - Abelson murine leukemia (BCR-ABL) levels. BCR-ABL levels are measured in patients by real-time quantitative polymerase chain reaction (RQ-PCR) testing of peripheral blood by the 24 months following the commencement of nilotinib therapy. MR4.5 corresponds to a BCR-ABL ratio 0.0032% international scale (IS) using RQ-PCR. If a post-baseline value for BCR-ABL is < 0.1 X the baseline value, the patient were classified as achieving a 1 log reduction in BCR-ABL. |
Baseline, 96 weeks (24 months)
|
Molecular Response (MR4.0) Rate: Percentage of Patients Who Have Achieved a 4.0-log Reduction in BCR-ABL Level Within 12 Months and 24 Months
Time Frame: Baseline, 48 weeks (12 months), 96 weeks (24 months)
|
Molecular Response (MR4.0) rate is defined as the percentage of patients who have achieved a 4-log reduction in BCR-ABL levels at 12 months and 24 months following the commencement of nilotinib therapy. Breakpoint cluster region - Abelson murine leukemia (BCR-ABL) levels are measured in patients by real-time quantitative polymerase chain reaction (RQ-PCR) testing of peripheral blood by the 24 months following the commencement of nilotinib therapy. MR4.0 corresponds to a BCR-ABL ratio 0.01% international scale (IS) using RQ-PCR. If a post-baseline value for BCR-ABL is < 0.1 X the baseline value, the patients were classified as achieving a 1 log reduction in BCR-ABL. |

|
Major Molecular Response (MMR) Rate: Percentage of Patients Who Have Achieved a 3 Log Reduction in BCR-ABL Levels Within 12 Months and 24 Months
Time Frame: Baseline, 48 weeks (12 months), 96 weeks (24 months)
|
Major Molecular Response (MMR) rate is defined as the percentage of patients who have achieved a 3 log reduction in BCR-ABL levels at 12 months and at 24 months following the commencement of nilotinib therapy.
Breakpoint cluster region - Abelson murine leukemia (BCR-ABL) levels are measured in patients by real-time quantitative polymerase chain reaction (RQ-PCR) testing of peripheral blood at the 12 and 24 months following the commencement of nilotinib therapy.
MMR corresponds to a BCR-ABL ratio 0.1% international scale (IS) using RQ-PCR.
If a post-baseline value for BCR-ABL is < 0.1 * the baseline Value, the patient will be classified as achieving a 1 log drop.

Deep molecular response (MR4.5) rate was defined as the percentage of patients who have achieved a 4.5-log reduction (MR4.5) in BCR-ABL levels during the 24 months following the commencement of nilotinib therapy. MR4.5 corresponds to a BCR-ABL ratio 0.0032% IS using RQ-PCR. If a post-baseline value for BCR-ABL is < 0.1 X the baseline value, the patient were classified as achieving a 1 log reduction in BCR-ABL. |

Time Frame: 96 weeks (24 months)
|
Breakpoint cluster region - Abelson murine leukemia (BCR-ABL) levels is measured in patients by real-time quantitative polymerase chain reaction (RQ-PCR) testing of peripheral blood by the 24 months following the commencement of nilotinib therapy. MR4.5 corresponds to a BCR-ABL ratio 0.0032% IS using RQ-PCR. The derivation of time to molecular response for patients in the study was measured from the date of first nilotinib use, defined as follows: Days to MR4.5 = date of assessment where BCR-ABL ratio is 0.0032% IS - date of baseline + 1. |

|
PFS was defined as the time from the date of baseline visit to the date of earliest progression-defining event: namely progression (or withdrawal due to progression to blast crisis (BC) or accelerated phase (AP) disease), or death from any cause. Patients who did not progress were censored at earliest of the following:
|
96 weeks (24 months)
|
Time to Event Free Survival (EFS)
Time Frame: 96 weeks (24 months)
|
EFS was defined as the time from date of baseline visit to the first occurrence of any of the following: Disease progression, treatment failure or death from any cause, whichever was earlier. Patients who did not have an event of interest were censored at earliest of the following:
|
96 weeks (24 months)
|

Time Frame: Baseline, week 12 (month 3)
|
The total number of patients that have showed improvement with respect to CTCAE grades at the time of the 12-week visit are reported.
Improved is defined as prior to, or at the time of the 12-week visit, the AE has completely resolved.

Mean M.D. Anderson Symptom Inventory - Chronic Myeloid Leukemia (MDASI-CML)
Time Frame: Baseline, week 12, 24, 48, 96
|
Quality of life was assessed using the M.D. Anderson Symptom Inventory - Chronic Myeloid Leukemia (MDASI-CML) self-administered questionnaire for adult CML patients.
The questionnaire consisted of 13 core questions in part I measuring the severity of symptoms, 6 questions in part 2 assessing the interference of symptoms on daily living.
The CML component of the MDASI provided an additional 7 CML-specific symptom items: diarrhea, swelling, rash/skin change, muscle soreness/cramping, bruising/bleeding easily, malaise, and headache.
In part I (13 questions) and the CML component (7 questions) each question was scored from 0 to 10 where 0 indicates a symptom is not present and 10 indicate the symptom is "as bad as you can imagine".
For part 1 the total score can therefore range from 0 to 130 and for CML 0 to 70.
Part 2 is also recorded on a 0 to 10 scale, but 0 now indicates that the symptom "did not interfere" and 10 "interfered completely".
The total score can range from 0 to 60.
