E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to compare the molecular response to ponatinib and imatinib in combination with the same induction and consolidation chemotherapy |
|
E.2.2 | Secondary objectives of the trial |
The most important secondary objective is to compare the event free survival with ponatinib and imatinib in combination with the same induction and consolidation chemotherapy.
Other considerations are to compare, the safety and tolerability of the drugs being investigated, the molecular response to the therapies, the overall survival and relapse-free survival and to measure and compare the activity of the therapies in the laboratory.

E.5 End points |
E.5.1 | Primary end point(s) |
Achievement of a molecular response defined by a BCR-ABL1/ABL1 (B/A) transcript ratio of ≤10-4 by the time point for MRD assessment after consolidation 2 or within 5 months after start of study treatment, whichever is earlier in arms 1 and 2 |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
After consolidation course 2 for arms 1 and 2 of the trial, or within 5 months after start of study treatment, whichever is earlier.
This takes into account substantial treatment delays or termination of study treatment prior to consolidation cycle 2 in the two chemotherapy-containing treatment arms. |
|
E.5.2 | Secondary end point(s) |
1. To compare the event free survival with ponatinib and imatinib in combination with the same induction and consolidation chemotherapy.
2. To compare the molecular response to induction and consolidation therapy with ponatinib in combination with either chemotherapy or with blinatumomab
3. To compare the safety and tolerability of ponatinib and imatinib in combination with induction and consolidation chemotherapy
4. To compare the efficacy of ponatinib and imatinib in combination with induction and consolidation chemotherapy as determined by overall survival and relapse-free survival
5. To determine the frequency of BCR-ABL1 tyrosine kinase domain mutations on therapy (T315I, p-loop and compound mutations) by standard molecular genetic techniques |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
1. Events will be recorded in all patients
2. Time to best molecular response (from start of treatment) in all patients
3. Adverse event grades 3 to 5 will be collected throughout IMP treatment
4. Relapse free survival, and overall survival - survival measured from trial entry until death
5. Detection of a T315I or p-loop mutation, or detection of a compound mutation, at any time during trial treatment and follow-up
