E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the optimal duration of consolidation treatment with nilotinib 300 mg BID in order that patients remain in treatment free remission (≥MR4.0) without molecular relapse 12 months after cessation of nilotinib.
|
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the proportion of patients who are eligible to suspend nilotinib therapy by achieving and maintaining a sustained ≥MR4.0 for at least 12 months during consolidation treatment with nilotinib 300 mg BID.
- To assess the kinetics of the molecular response in patients during induction/consolidation treatment with nilotinib 300 mg BID.
- To assess the kinetics of the molecular response in patients during the TFR phase of the study in the two treatment arms.
- To assess the progression-free survival (PFS) rate during the TFR phase of the study in the two treatment arms.
- To assess treatment-free survival (TFS) during the TFR phase of the study in the two treatment arms.
- To assess the overall survival (OS) rate during the TFR phase of the study in the two treatment arms.
- To assess the safety profile of nilotinib during the induction/consolidation treatment phase, the TFR phase, and during the treatment re-initiation phase.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients eligible for inclusion in this study have to meet all of the following criteria:
•Confirmed diagnosis of chronic phase Ph+ CML
•Previous first-line treatment with imatinib for a minimum of 2 years;
•Patient in complete cytogenetic response;
Additional inclusion criteria as per protocol apply. |
|
E.4 | Principal exclusion criteria |
Patients eligible for this study must not meet any of the following criteria:
•Previous achievement of MR4.0 at study entry;
•Previous treatment with other target cells inhibitors other than imatinib;
•Patients with any history of detectable atypical Leukemia transcripts or patients with detectable atypical leukemia transcripts at screening;
•Previous anticancer agents for Chronic myeloid leukemia other than imatinib except for cytoreduction;
•Severe and/or uncontrolled concurrent medical disease that in the opinion of the investigator could cause unacceptable safety risks or compromise compliance with the protocol;
•History of other active malignancies within the 5 years prior to study entry with the exception of previous or concomitant basal cell skin cancer and previous carcinoma in situ treated curatively;
•Patients who have not recovered from prior surgery;
•Treatment with other investigational agents within 4 weeks of Day 1;
•Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drug.
Additional exclusion criteria as per protocol apply. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the number of patients who remain in treatment free remission (≥MR4.0) ,without molecular relapse, at the end of 12 months in the TFR phase of the study, in the nilotinib 12 months consolidation treatment arm (arm 1) versus the nilotinib 24 months consolidation treatment arm (arm 2). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 months after treatment cessation |
|
E.5.2 | Secondary end point(s) |
- The proportion of patients who have achieved a sustained ≥MR4.0 (defined as having 4 out of 5 quarterly assessments of ≥MR4.0 by a EUTOS standardized laboratory over the last 12 months and the last assessment before randomization is at least MR4.0) during the consolidation treatment phase of the study.
- The proportion of patients who achieve MR4.0 or MR4.5 on the study at selected time points during the induction/consolidation phase of the study.
- The proportion of patients who maintain in MR4.0 or MR4.5 on the study at selected time points during the TFR phase in each one of the two treatment arms
- PFS defined as progression to AP/BP or death, where the "failure" event is the earliest occurrence of either of these events; Kaplan-Meier (KM) estimation of PFS is measured from the date of start of the nilotinib TFR phase to the date of the earliest failure event. Patients not known to have recurred or died on or before the cut-off date for the KM analysis will have their PFS interval censored at the earlier of the date of their last assessment (cytogenetic, hematology or extramedullary) for patients who are still on study, and at the date of last contact for patients who are in follow-up.
- TFS is defined as lack of any of the following events: loss of MMR, confirmed loss of MR4.0, re-start of nilotinib treatment, progression to AP/BP, or death from any cause;KM estimation of TFS, which is measured from the date of the start of the nilotinib TFR phase to the date of the earliest of the following: loss of MMR, confirmed loss of MR4.0, re-start of nilotinib treatment, progression to AP/BP, or death from any cause.
- Overall survival is defined as the time from start of the TFR phase to the time of death due to any cause. For patients without any event on or before the cut-off date, survival time will be censored at the date of their last assessment for patients who are still on study, and at the date of last contact for patients who are in follow-up.
- Descriptive statistics on adverse events, laboratory abnormalities and clinically notable ECG and other safety parameters during the study |
