Primary | Participants With Hematologic Response | The primary efficacy variable was hematologic response, a composite endpoint defined as the overall of complete hematologic response (CHR), and of no evidence of leukemia (NEL) and of the return to chronic phase (RTC). | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Duration of Hematologic Response | Duration of hematologic response is defined as the time from the first documentation of the hematologic response to the date of the first documentation of the disease progression | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Complete Cytogenetic Response (CCyR) Rate | Durations of complete cytogenetic response is defined as the time from the first documentation of the major/complete response to the first documentation of the disease progression. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Major (Complete/Partial) Cytogenetic Response Rate | Durations of major/complete cytogenetic response is defined as the time from the first documentation of the major/complete response to the first documentation of the disease progression. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Complete Cytogenetic Response (CCyR) and Overall (Complete/Partial/Minor/Minimal) Cytogenetic Response (OCyR) Rates | Cytogenetic response was assessed by bone marrow assessment based on the percentage of Ph+ metaphases by karyotype analysis on a bone marrow aspirate, was ideally assessed from a minimum of 20 metaphases in each bone marrow sample. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Duration of Major Cytogenetic Response | The duration of response was defined as the time between the first documented response to the date of discontinuation due to progressive disease (PD) or death. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Major (MMR) and Complete (CMR) Molecular Response Rates | Molecular response was defined as major (= 0.1% on the International Scale) and complete [absence of fusion gene of the BCR and ABL genes (BCR-ABL) on an quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay with a sensitivity of at least 4.5 logs below baseline]. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | BCR-ABL Mutations of Participants at Study Entry and, in Responding Participants and at the Time of Disease Progression | A fusion gene of the BCR and ABL genes (BCR-ABL) messenger ribose nucleic acid (mRNA) expression (molecular response) was performed by quantitative polymerase chain reaction (qPCR) and mutational analysis was performed by direct sequencing technology, and both analyses were performed by Genzyme. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Progression Free Survival (PFS) | Progressions free survival is defined as time between Day 1 cycle 1 and time to first documented disease progression or death. Disease progression will be determined as per response criteria. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Overall Survival Time | Overall survival time is defined as the time from the treatment start to the date of death due to any reason. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Time to Peak Concentration (Tmax) of Panobinostat | Tmax is defined as the time at which the Cmax occurs. It will be obtained from the Tmax parameter calculated by WinNonlin®. If there is no measurable Cmax in the subject's Pharmacokinetic (PK) profile, then Tmax will be missing for that subject. Tmax will be reported in units of h. | Pre-dose, 0.25, 1-2, and 3-4 hours post dose on Day 1 and Day 8 | |
Secondary | Maximum Plasma Concentration (Cmax) of Panobinostat | Cmax is defined as the maximum observed drug concentration observed in plasma over all PK sample concentrations. It will be obtained from the Cmax parameter calculated by WinNonlin®. If there is no measurable concentration in the subject's PK profile, then Cmax will be missing for that subject. Cmax will be reported in units of ng/mL. | Pre-dose, 0.25, 1-2, and 3-4 hours post dose on Day 1 and Day 8 | |
Secondary | Area Under the Plasma Concentration (AUC0-24) of Panobinostat | Area under the curve (AUC) is defined as the area under concentration-time curve as a measure of drug exposure. The area under the plasma concentration-time curve from time zero to 24 hours. | Pre-dose, 0.25, 1-2, and 3-4 hours post dose on Day 1 and Day 8 | |

Secondary | Time of Clast (Tlast) of Panobinostat | Time of Clast (Tlast) will be obtained from the Tlast parameter calculated by WinNonlin®. If there is no measurable concentration in the subject's PK profile, then Tlast will be missing for that participants. Tlast will be reported in units of h. | Pre-dose, 0.25, 1-2, and 3-4 hours post dose on Day 1 and Day 8 | |
Secondary | QT Interval (QTc) in Participants Receiving Oral Panobinostat at Baseline and Change From Baseline to Extreme Value | QTc monitoring was performed on specified days (Cycle1: Day1, 5 and 26), as well as a single pre-dose ECG once weekly during Cycle1: Week2 and Week3, Cycle2, and all subsequent cycles. Patient eligibility was ensured by a screening QTcF interval calculated by eResearchTechnology(eRT) prior to the baseline assessments. Treatment decisions were based on QTc determined by the automated reading at the investigational site (commonly used the Bazett's correction,QTcB) or measured and calculated by trained personnel at the site. Dosing relied on the investigator's assessment of the 6 baseline ECGs (the average of the 6pre-dose QTc intervals) performed prior to Cycle1/Day1 dosing, of the 3pre-dose ECGs during Cycle1:Day5 and 26, and of the single pre-dose ECGs performed once weekly for the remaining weeks of Cycle1 and subsequent cycles. The Baseline and Change From Baseline to Extreme Value QTcF interval for analysis was calculated by eRT based on the 6 baseline ECGs obtained on Cycle1/Day1. | From Start of the Study up to Study Termination (approximately up to 18 Months). | |
Secondary | Safety and Tolerability of Panobinostat | Adverse Events (AE) are defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome or disease which either occurs during study, having been absent at baseline, or, if present at baseline, appears to worsen. Serious adverse events are any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgment of investigators represent significant hazards | From Start of the Study up to Study Termination (approximately up to 18 Months). |
