About this study
Official title: International Phase 3 Trial in Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia (Ph+ALL) Testing Imatinib in Combination With Two Different Cytotoxic Chemotherapy Backbones
This randomized phase III trial studies how well imatinib mesylate works in combination with two different chemotherapy regimens in treating patients with newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukemia (ALL). Imatinib mesylate has been shown to improve outcomes in children and adolescents with Philadelphia chromosome positive (Ph+) ALL when given with strong chemotherapy, but the combination has many side effects. This trial is testing whether a different chemotherapy regimen may work as well as the stronger one but have fewer side effects when given with imatinib. The trial is also testing how well the combination of chemotherapy and imatinib works in another group of patients with a type of ALL that is similar to Ph+ ALL. This type of ALL is called "ABL-class fusion positive ALL", and because it is similar to Ph+ ALL, is thought it will respond well to the combination of agents used to treat Ph+ ALL.
Read the detailed description
PRIMARY OBJECTIVE:
- To compare disease-free survival (DFS) of standard risk (SR) pediatric Philadelphia chromosome (Ph)+ acute lymphoblastic leukemia (ALL) treated with continuous imatinib mesylate (imatinib) combined with either a high-risk Children's Oncology Group (COG) ALL chemotherapy backbone or the more intensive European (Es)PhALL chemotherapy backbone.
SECONDARY OBJECTIVES:
- To compare DFS of SR pediatric Ph+ and ABL-class 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.
II. To determine the feasibility of administration of imatinib after allogeneic hematopoietic stem cell transplantation (HSCT) in high risk (HR) Ph+ ALL patients.
III. 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.
IV. To compare rates of grade 3 or higher infections in standard risk (SR) Ph+ ALL patients between the two randomized arms.
- To evaluate EFS and overall survival (OS) of all eligible Ph+ALL patients enrolled on the study.
VI. To evaluate OS in SR Ph+ ALL patients. VII. To evaluate OS in HR Ph+ ALL patients. VIII. To evaluate EFS and OS of all eligible ABL-class fusion positive ALL patients enrolled on the study.
EXPLORATORY OBJECTIVES:
- To describe the toxicities associated with post-HSCT administration of imatinib in HR Ph+ALL patients.
II. To evaluate the long-term toxicities in SR Ph+ ALL patients treated with chemotherapy plus imatinib (no transplant), overall and between both randomized arms.
III. To determine prognostic significance of minimal residual disease (MRD) in Ph+ ALL at various time points during therapy.
IIIa. To evaluate MRD in HR patients just prior to HSCT and then at regular intervals post-HSCT and explore the association of these measurements with long-term outcome.
IIIb. To evaluate concordance of MRD assessments made by IGH-T cell receptor (TCR) polymerase chain reaction (PCR) assay and next generation sequencing (NGS) assays.
IV. To determine and validate if IKZF1 deletions alone (IKZF1del) or with other transcription factor deletions (ie, IKZF1 plus subtype [IKZF1plus]) or other identified genetic lesions predict poor outcomes in Ph+/ABL-class Ph-like ALL in patients treated on AALL1631.
- To determine the frequency and prognostic significance of p190 and p210 BCR::ABL1 fusion variants in pediatric Ph+ ALL/ABL-class Ph-like ALL.
VI. To measure adherence to oral chemotherapeutic agents (imatinib, 6-mercaptopurine and methotrexate) during the maintenance phase in SR Ph+ ALL patients.
VIa. To identify factors associated with poor adherence. VIb. To determine association between relapse risk and adherence to each oral chemotherapeutic agent (separately and combined).
VII. To measure adherence to imatinib after allogeneic HSCT in HR Ph+ ALL patients and identify factors associated with poor adherence.
VIII. To compare DFS of SR ABL-class 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.
IX. Other secondary and exploratory aims described above for Ph+ ALL patients (either SR or HR), if applicable, will be evaluated in ABL-class fusion positive ALL patients.
- Secondary and exploratory aims described above for Ph+ ALL patients (either SR or HR), if applicable and feasible, will be evaluated in the super set of Ph+ and ABL-class fusion positive ALL patients.
XI. To determine the potential therapeutic impact of major secondary events via pharmacologic inhibitor screens in existing/engineered cell models of Ph+ and ABL-class Ph-like ALL harboring secondary events and to test the in vivo activity of the most compelling candidate compounds from pilot studies using patient-derived xenograft (PDX) models established from Ph+ and ABL-class Ph-like ALL samples collected from patients treated on AALL1631.
XII. To decipher the molecular and cellular heterogeneity of chronic myelogenous leukemia (CML)-like versus typical Ph+ ALL via single-cell genomics and functional assays and investigate CML-like phenotypes via single-cell ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) sequencing to identify distinct transcriptomic and mutational profiles that will provide novel opportunities for diagnostic and therapeutic interventions.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This randomized phase III trial studies how well imatinib mesylate works in combination with two different chemotherapy regimens in treating patients with newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukemia (ALL). Imatinib mesylate has been shown to improve outcomes in children and adolescents with Philadelphia chromosome positive (Ph+) ALL when given with strong chemotherapy, but the combination has many side effects. This trial is testing whether a different chemotherapy regimen may work as well as the stronger one but have fewer side effects when given with imatinib. The trial is also testing how well the combination of chemotherapy and imatinib works in another group of patients with a type of ALL that is similar to Ph+ ALL. This type of ALL is called "ABL-class fusion positive ALL", and because it is similar to Ph+ ALL, is thought it will respond well to the combination of agents used to treat Ph+ ALL.
Detailed description
PRIMARY OBJECTIVE:
- To compare disease-free survival (DFS) of standard risk (SR) pediatric Philadelphia chromosome (Ph)+ acute lymphoblastic leukemia (ALL) treated with continuous imatinib mesylate (imatinib) combined with either a high-risk Children's Oncology Group (COG) ALL chemotherapy backbone or the more intensive European (Es)PhALL chemotherapy backbone.
SECONDARY OBJECTIVES:
- To compare DFS of SR pediatric Ph+ and ABL-class 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.
II. To determine the feasibility of administration of imatinib after allogeneic hematopoietic stem cell transplantation (HSCT) in high risk (HR) Ph+ ALL patients.
III. 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.
IV. To compare rates of grade 3 or higher infections in standard risk (SR) Ph+ ALL patients between the two randomized arms.
- To evaluate EFS and overall survival (OS) of all eligible Ph+ALL patients enrolled on the study.
VI. To evaluate OS in SR Ph+ ALL patients. VII. To evaluate OS in HR Ph+ ALL patients. VIII. To evaluate EFS and OS of all eligible ABL-class fusion positive ALL patients enrolled on the study.
EXPLORATORY OBJECTIVES:
- To describe the toxicities associated with post-HSCT administration of imatinib in HR Ph+ALL patients.
II. To evaluate the long-term toxicities in SR Ph+ ALL patients treated with chemotherapy plus imatinib (no transplant), overall and between both randomized arms.
III. To determine prognostic significance of minimal residual disease (MRD) in Ph+ ALL at various time points during therapy.
IIIa. To evaluate MRD in HR patients just prior to HSCT and then at regular intervals post-HSCT and explore the association of these measurements with long-term outcome.
IIIb. To evaluate concordance of MRD assessments made by IGH-T cell receptor (TCR) polymerase chain reaction (PCR) assay and next generation sequencing (NGS) assays.
IV. To determine and validate if IKZF1 deletions alone (IKZF1del) or with other transcription factor deletions (ie, IKZF1 plus subtype [IKZF1plus]) or other identified genetic lesions predict poor outcomes in Ph+/ABL-class Ph-like ALL in patients treated on AALL1631.
- To determine the frequency and prognostic significance of p190 and p210 BCR::ABL1 fusion variants in pediatric Ph+ ALL/ABL-class Ph-like ALL.
VI. To measure adherence to oral chemotherapeutic agents (imatinib, 6-mercaptopurine and methotrexate) during the maintenance phase in SR Ph+ ALL patients.
VIa. To identify factors associated with poor adherence. VIb. To determine association between relapse risk and adherence to each oral chemotherapeutic agent (separately and combined).
VII. To measure adherence to imatinib after allogeneic HSCT in HR Ph+ ALL patients and identify factors associated with poor adherence.
VIII. To compare DFS of SR ABL-class 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.
IX. Other secondary and exploratory aims described above for Ph+ ALL patients (either SR or HR), if applicable, will be evaluated in ABL-class fusion positive ALL patients.
- Secondary and exploratory aims described above for Ph+ ALL patients (either SR or HR), if applicable and feasible, will be evaluated in the super set of Ph+ and ABL-class fusion positive ALL patients.
XI. To determine the potential therapeutic impact of major secondary events via pharmacologic inhibitor screens in existing/engineered cell models of Ph+ and ABL-class Ph-like ALL harboring secondary events and to test the in vivo activity of the most compelling candidate compounds from pilot studies using patient-derived xenograft (PDX) models established from Ph+ and ABL-class Ph-like ALL samples collected from patients treated on AALL1631.
XII. To decipher the molecular and cellular heterogeneity of chronic myelogenous leukemia (CML)-like versus typical Ph+ ALL via single-cell genomics and functional assays and investigate CML-like phenotypes via single-cell ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) sequencing to identify distinct transcriptomic and mutational profiles that will provide novel opportunities for diagnostic and therapeutic interventions.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Allogeneic Hematopoietic Stem Cell Transplantation, Calaspargase Pegol and Cyclophosphamide in people with Acute Lymphoblastic Leukemia and B Acute Lymphoblastic Leukemia, run by Children's Oncology Group at 226 sites in 19 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 24 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 5 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 226 sites in United States, Canada, Australia, Puerto Rico, Germany and 14 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease free survival (DFS) of Randomized Arms (standard risk [SR] Philadelphia chromosome [Ph+] acute lymphoblastic leukemia [ALL] patients) (time frame: Up to 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Oct 2026.
