説明
Inclusion Criteria:
Diagnosis of chronic myeloid leukemia associated with BCR-ABL quantifiable by RQ-PCR Documented CCyR by bone marrow or BCR-ABL<1% IS in the past 12 months Persistent disease demonstrated by two PCR positive tests 3 months apart both during the past 6 months.
Treatment with imatinib for at least 2 years with 400 mg or 600 mg and a stable dose No other current or planned anti-leukemia therapies
Exclusion Criteria:
Patient has evidence of rising PCR (a confirmed >1 log increase in previous 6 months) Patient has received another investigational agent within last 6 months or tyrosine kinase inhibitors (TKIs) other than imatinib Prior allogeneic stem cell transplantation
Impaired cardiac function including any one of the following:
Inability to monitor the QT interval on electrocardiogram (ECG) Long QT syndrome or a known family history of long QT syndrome. Clinically significant resting brachycardia (<50 beats per minute) QTc > 450 msec on 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-screened for QTc Myocardial infarction within 12 months prior to starting study Other clinically significant uncontrolled heart disease (e.g. unstable angina, congestive heart failure or uncontrolled hypertension) History of or presence of clinically significant ventricular or atrial tachyarrhythmias Administration of cytokine therapy (e.g. G-CSF, GM-CSF or SCF) within 4 weeks prior to study entry

Rate of Confirmed Best Cumulative Complete Molecular Response (CMR)
時間枠:12 months
|
The rate of confirmed best cumulative CMR was defined as the number of participants who had confirmed CMR during the first 12 months of treatment after the randomization date.
Participants who achieved confirmed best cumulative CMR during the first 12 months were considered responders.
Participants who dropped out early or who did not provide sufficient data for any reason were considered to be non-responders.
The definition of CMR is undetectable BCR-ABL (fusion gene formed between bcr gene from chromosome 22 and abl gene from chromosome 9) where BCR-ABL ratio in % international scale (IS) ≤ 0.00001 by real-time quantitative polymerase chain reaction (RQ-PCR) where there was no detectable BCR-ABL and 1) the test had a sensitivity of at least 4.5 logs below the standardized baseline; 2) RQ-PCR negativity was confirmed on the next RQ-PCR sample (usually 3 months later); and 3) the date of confirmed CMR was the date of the first of two negative results with sensitivity >4.5 logs.

Rate of Confirmed Best Cumulative CMR
時間枠:24 months, 36 month, 48 months
|
The rate of confirmed best cumulative CMR was defined as the number of participants who had confirmed CMR during the 24, 36 and 48 months post treatment after the randomization date.
Participants who achieved confirmed best cumulative CMR during the first 12 months were considered responders.
Participants who dropped out early or who did not provide sufficient data for any reason were considered to be non-responders.
The definition of CMR is undetectable BCR-ABL (fusion gene formed between bcr gene from chromosome 22 and abl gene from chromosome 9) where BCR-ABL ratio in % international scale (IS) ≤ 0.00001 by RQ-PCR where there was no detectable BCR-ABL and 1) the test had a sensitivity of at least 4.5 logs below the standardized baseline; 2) RQ-PCR negativity was confirmed on the next RQ-PCR sample (usually 3 months later); and 3) the date of confirmed CMR was the date of the first of two negative results with sensitivity >4.5 logs.

Progression Free Survival (PFS)
時間枠:48 months
|
PFS was defined as the time from the date of randomization to the date of the earliest documented progression-defining event as follows: transformation to blast crisis or accelerated phase disease, or death from any cause.
|
48 months
|
|
Event-free Survival
時間枠:48 months
|
Event-free survival was defined as the time from the date of randomization to the date of first occurrence of any of the following events on study treatment: loss of complete hematological response, confirmed loss of complete cytogenetic response (CCyR), confirmed loss of major molecular response (MMR), death from any cause during treatment, progression to the accelerated phase or blast crisis of chronic myelogenous leukemia (CML) per European Leukemia Network (ELN) criteria, whichever was earliest.

48 months

Overall Survival
時間枠:48 months
|
Overall survival was defined as the time from the date of randomization to the date of death due to any cause at any time during the study, including the follow-up period after discontinuation of treatment.
