Primary
| Measure | Time frame |
|---|---|
| Main Objective: To select molecules in combination or sequentially with imatinib, nilotinib, dasatinib, bosutinib or ponatinib potentially able to produce a 25% increase in the Cumulative Incidence of MR4.5 as compare to control. ;Secondary Objective: A.To determine the safety of selected therapies B.To determine the rate of MR4 by 12, 24, 36, 48 months in experimental and control arms C.To determine the rates of MR4.5 by 24, 36, 48 months in experimental and control arms D.To determine the rate of undetectable BCR-ABL1 transcript (sensitivity 40000 ABL copies) by 12, 24, 36, 48 months in experimental and control arms E.To estimate treatment free remission (TFR) in patients eligible for discontinuation studies F.To investigate the relationship between biological activity and the clinical efficacy of the selected therapies G.To assess the effects of the treatments on the number and clonogenicity of CML stem cells and other biological markers of interest H.To estimate duration of response, progression-free survival, event free survival and overall survival. ;Primary end point(s): The primary end-point is the cumulative incidence of patients achieving a deep molecular response defined by MR4.5 or deeper (BCR-ABLIS = 0.0032 %) by 12 months.;Timepoint(s) of evaluation of this end point: 12 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Adverse events 2. The cumulative rate of patients achieving MR4.5 by 24, 36, 48 months in experimental and control arms 3. The cumulative rate of patients achieving MR4 by 12, 24, 36, 48 months in experimental and control arms 4. The cumulative rate of patients with undetectable BCR-ABL1 transcript (sensitivity 40000 ABL copies) by 12, 24, 36, 48 months in experimental and control arms 5. The rate of patients in treatment free remission during follow-up 6. Measurement of number and clonogenicity of CML stem cells using the leukemic stem cell markers followed by flow cytometry analysis and the LTC-IC assay and others markers (ancillary study) 7. Survival, progression free survival, event free survival, duration of response ;Timepoint(s) of evaluation of this end point: 12, 24, 36, 48 months | — |
