- Disease free survival (DFS) of Randomized Arms (standard risk [SR] Philadelphia chromosome [Ph+] acute lymphoblastic leukemia [ALL] patients) [ Time Frame: Up to 3 years ]Three-year DFS and 95% confidence intervals (CI) of SR Ph+ ALL patients treated continuous imatinib mesylate with high risk Children's Oncology Group (COG)-ALL chemotherapy backbone or more intensive European (Es)PhALL chemotherapy backbone.
- DFS on Randomized Arms (SR Ph+ ALL and ABL-class fusion positive patients) [ Time Frame: Up to 3 years ]Three-year DFS (time from randomization to relapse, second malignancy, or death in complete remission) and 95% CI 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.
- Feasibility of post hematopoietic stem cell transplantation (HSCT) imatinib mesylate administration after allogenic HSCT in high risk Ph+ ALL patients [ Time Frame: Up to 2 years ]The proportion of patients who receive at least 75% of intended doses.
- Event free survival (EFS) of high risk pediatric Ph+ ALL patients treated with EsPhALL chemotherapy, HSCT in first complete remission, and post-HSCT imatinib mesylate [ Time Frame: Up to 3 years ]
Will be estimated using the Kaplan-Meier method and standard errors estimated by Greenwood.
Three-year EFS and 95% CI for high risk pediatric Ph+ ALL patients treated with EsPhALL chemotherapy, HSCT in first complete remission, and post-HSCT imatinib mesylate. EFS is defined as the time from the date of bone marrow for minimal residual disease (MRD) assessment at end-IB to first event (resistant disease [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], second malignancy, or death in complete remission), or time to last follow-up for patients without events.
- Incidence of grade 3 or higher infections in standard risk Ph+ ALL patients in the two randomized arms [ Time Frame: Up to 3 years ]Evaluated according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The rate of infections during the post IB/pre-maintenance phases of treatment will be described for each randomization group.
- EFS of all Ph+ patients [ Time Frame: Up to 3 years ]Three-year EFS and 95% CI for Ph+ ALL patients. EFS here is defined as the time from enrollment until resistant disease, relapse, progressive disease post-HSCT, second malignant, or death, whichever occurs first.
- Overall survival (OS) of all Ph+ patients [ Time Frame: Up to 3 years ]Three-year OS and 95% CI for Ph+ ALL patients. OS is defined as the time from study enrollment to death from any cause.
- OS of SR Ph+ patients [ Time Frame: Up to 3 years ]Three-year OS (time from randomization to death from any cause) and 95% CI of SR pediatric Ph+ patients
- OS of SR Ph+ patients by randomization group [ Time Frame: Up to 3 years ]Three-year OS (time from randomization to death from any cause) and 95% CI of SR pediatric Ph+ patients by randomization group: treated with continuous imatinib combined with either a high-risk COG-ALL chemotherapy backbone or the more intensive EsPhALL chemotherapy backbone.
- OS of high risk Ph+ patients [ Time Frame: Up to 3 years ]Three-year OS (time from the date of MRD assessment at end-IB to death from any cause) and 95% CI of HR pediatric Ph+ patients.
- EFS of all eligibility ABL-class fusion positive ALL patients [ Time Frame: Up to 3 years ]Three-year EFS (time from enrollment until resistant disease, relapse, progressive disease post-HSCT, second malignancy, or death, whichever occurs first) and 95% CI of ABL-class fusion positive patients.
- OS of all eligibility ABL-class fusion positive ALL patients [ Time Frame: Up to 3 years ]Three-year OS (the time from study enrollment to death from any cause) and 95% CI of ABL-class fusion positive patients.
- Incidence of toxicities associated with post-HSCT administration of imatinib mesylate [ Time Frame: Up to 1 year post-HSCT ]Evaluated according to NCI CTCAE version 5.0. Frequencies of target toxicities in high risk patients after the initiation of post-HSCT imatinib mesylate will be described. For the high risk patients, the specific targeted toxicities will include grade 4 neutropenia, grade 4 thrombocytopenia, grade 3 or higher bilirubin, grade 4 or higher transaminitis, and grade 3 or higher infection.
- Incidence of long-term toxicities in patients treated with chemotherapy plus imatinib mesylate (no transplant) in both arms [ Time Frame: Up to 3 years ]Evaluated according to NCI CTCAE version 5.0. Frequencies of long-term toxicities will be described and differences between randomized arms will be explored. Specific long-term toxicities to be explored include cardiac (echocardiographic abnormalities, including decreased left ventricular (LV) function and decreased LV wall thickness), growth (linear height, bone age), and second malignant neoplasm.
- MRD measured by IGH-T cell receptor (TCR) polymerase chain reaction (PCR) and next generation sequencing (NGS) assay [ Time Frame: Up to 6 months ]For all patients, frequencies and prognostic significance (DFS, EFS, OS) will be explored for MRD levels (i.e., MRD negative, detectable at < 5 x 10^-4, and dectectable at >= 5 x 10^-4) at end of Induction IB.
- MRD in high risk Ph+ patients measured by IGH-TCR PCR and NGS assay [ Time Frame: Up to 3 years ]The outcome of high risk Ph+ patients will be described, including proportion of patients who achieve MRD-negativity just prior to HSCT, and at regular intervals post-HSCT. Associations between these findings and long-term outcomes (e.g., OS, DFS) will be explored.
- MRD assessments made by IGH-TCR PCR assay and NGS assay [ Time Frame: Up to 3 years ]Concordance of MRD assessments made by IGH-TCR PCR assay and NGS assay will be described and evaluated. Scatter plots and diagrams will be used to examine agreements and patterns of agreement or any differences found. Concordance will be explored both for the overall cohort, as well as by risk group. The increased sensitivity of the NGS will be closely examined to find cases where the MRD levels are detectable by NGS but undetectable by PCR, as well as cases in which one test yields results and the other does not (test failure). Prognostic relationships on outcomes for these subjects will be inspected.
- IKZF1 gene aberrations and deletions [ Time Frame: Up to 3 years ]For both standard risk and high risk groups, frequencies and prognostic significance (OS, DFS) will be explored for IKZF1 gene aberrations and deletions.
- Frequency of p190 and p210 BCR-ABL1 fusion variants [ Time Frame: Up to 3 years ]For both standard risk and high risk groups, frequencies and prognostic significance (OS, DFS) will be explored for p190 and p210 BCR-ABL1 fusion variants in pediatric Ph+ ALL.
- Adherence to oral chemotherapeutic agents in standard risk Ph+ ALL patients [ Time Frame: Up to 2 years ]Adherence to imatinib mesylate, 6-mercaptopurine, and methotrexate will be evaluated in COG-enrolled participants using an electronic monitoring device. Adherence rate will be computed for each month of adherence monitoring. Longitudinal binomial regression will be conducted using generalized estimating equation methods by modeling monthly adherence rate as an unstructured mean model using five indicator variables of time for the study months. Time in months will also be treated as a continuous variable to explore temporal trends in adherence rate. Compound symmetry will be assumed as the working correlation matrix over time. Covariates that will be considered for adjustment include those hypothesized to be predictors of adherence, annual household income, parental education, time since start of maintenance, risk classification for ALL, and imatinib, 6-mercaptopurine (6MP), and methotrexate dose-intensity.
