Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients should be enrolled on National ALL protocol prior to enrollment on EsPhALL2017/COGAALL1631. Regardless of initial frontline protocol baseline diagnostic samples must be available to develop an MRD probe. Diagnostic samples will be collected and analyzed according to the procedures of the National front-line protocol. 2. > 1 year and =65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: 1. Known history of chronic myelogenous leukemia (CML). 2. ALL developing after a previous cancer treated with cytotoxic chemotherapy. 3. Active, uncontrolled infection or active systemic illness that requires ongoing vasopressor support or mechanical ventilation 4. Down syndrome 5. Pregnancy 6. Breast Feeding 7. Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of treatment according to protocol. 8. Patients with congenital long QT syndrome, history of ventricular arrhythmias or heart block. 9. Prior treatment with dasatinib, or any TKI inhibitor other than imatinib.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare disease-free survival (DFS) of Standard Risk (SR) Ph+ ALL patients treated with continuous imatinib combined with either the EsPhALL chemotherapy backbone (Arm A) or a less intensive a high-risk COG ALL chemotherapy backbone (Arm B), according to the randomization result. A non-inferiority design will be applied in order to evaluate whether there is significant erosion in DFS in SR patients treated with the less intensive Arm B compared with Arm A.;Secondary Objective: 1. To compare disease free survival (DFS) of SR pediatric Ph+ and ABLclass fusion positive ALL patients treated with continuous imatinib combined with either a high-risk COG-ALL chemotherapy backbone or the more intensive EsPhALL chemotherapy backbone. To determine the feasibility of administration of imatinib after allogeneic HSCT in High Risk (HR) Ph+ ALL patients. 2. To determine event-free-survival (EFS) of HR pediatric Ph+ ALL patients treated with EsPhALL chemotherapy, HSCT in first complete remission and post-HSCT imatinib. 3. To compare rates of Grade 3 or higher infections in SR Ph+ ALL patients between the two randomized arms. 4. To evaluate EFS and overall survival (OS) of all eligible Ph+ALL patients enrolled on the study. 5. To evaluate OS in SR Ph+ ALL patients. 6. To evaluate OS in HR Ph+ ALL patients. 7. To evaluate EFS and OS of all eligible ABL-class fusion positive ALL patients enrolled on the study. ;Primary end point(s): DFS, defined as the time from randomization to first event (relapse, second malignancy, or death in complete remission) or time to last follow-up for patients without events.;Timepoint(s) of evaluation of this end point: from randomization to first event (relapse, second malignancy, or death in complete remission) or time to last follow-up for patients without events. | — |

| Secondary end point(s): 1. To compare disease free survival (DFS) of SR pediatric Ph+ and ABL-class fusion positive patients treated with continuous imatinib combined with either a high-risk COG-ALL chemotherapy backbone or the more intensive EsPhALL chemotherapy backbone. The DFS is defined as the time from randomization to first event (relapse, second malignancy, or death in complete remission) or time to last follow-up for patients without events. DFS comparison will be done according to the intention to treat (ITT) principle by assigned arm. Since only limited data will be available for ABL-class fusion positive patients, applicability of the pooled analysis to this subgroup is questionable. A separate analysis for the ABL-class fusion positive patients is therefore planned as exploratory aim. 2. To determine the feasibility of administration of imatinib after allogeneic HSCT in HR Ph+ ALL patients. 3. To determine event free survival (EFS) of HR pediatric Ph+ ALL patients treated with EsPhALL chemotherapy, HSCT in first complete remission and post-HSCT imatinib. EFS is defined as the time from the date of bone marrow for MRD assessment at end-IB to first event (resistant disease [i.e. MRD=10^-2 or morphologic residual disease at end of Consolidation Block 3], relapse, progressive disease [i.e. MRD = 10^-2 at two post-HSCT time points separated by at least 2 weeks obtained at Day 90 or later from HSCT], second malignancy, or death in complete remission) or time to last follow-up for patients without events. 4. To compare rates of Grade 3 or higher infections in Standard Risk Ph+ ALL patients between the two randomized arms. 5. To evaluate EFS and overall survival (OS) of all eligible Ph+ ALL patients enrolled on the study. 6. To evaluate OS in SR Ph+ ALL patients. OS as secondary endpoint is defined as the time from randomization to death from any cause. 7. To evaluate OS (defined as ti | — |
