About this study
Official title: Risk-Stratified Randomized Phase III Testing of Blinatumomab (NSC#765986) in First Relapse of Childhood B-Lymphoblastic Leukemia (B-ALL)
This randomized phase III trial studies how well blinatumomab works compared with standard combination chemotherapy in treating patients with B-cell acute lymphoblastic leukemia that has returned after a period of improvement (relapsed). Immunotherapy with blinatumomab may allow the body's immune system to attack and destroy some types of leukemia cells. It is not yet known whether blinatumomab is more effective than standard combination chemotherapy in treating relapsed B-cell acute lymphoblastic leukemia.
Read the detailed description
PRIMARY OBJECTIVES:
- To compare disease free survival (DFS) of high-risk (HR) and intermediate-risk (IR) relapse B-cell acute lymphoblastic leukemia (B-ALL) patients who are randomized following induction block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR randomization) as a part of a treatment regimen prior to allogeneic bone marrow transplantation. (Closed to enrollment effective September 18, 2019) II. To compare the DFS of low risk (LR) relapse B-ALL patients who are randomized following block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR randomization). (Closed to enrollment effective September 30, 2019)
SECONDARY OBJECTIVES:
- To compare overall survival (OS) of HR and IR relapse B-ALL patients who are randomized following induction block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR randomization). (Closed to enrollment effective September 18, 2019) II. To compare OS of LR relapse B-ALL patients who are randomized following block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR randomization).
EXPLORATORY OBJECTIVES:
- To compare the rates of minimal residual disease (MRD) >= 0.01% at the end of block 2 and block 3 for HR and IR relapse B-ALL patients in HR/IR randomization.
II. To estimate, for treatment failure (TF) patients not previously receiving blinatumomab, the hematologic complete remission rate (CR), rate of MRD < 0.01%, and proportion able to proceed to hematopoietic stem cell transplant (HSCT) in CR after treatment with blinatumomab.
III. To assess the feasibility and safety of rapid taper of immune suppression for the subset of HSCT patients with MRD >= 0.01% pre- and/or post-HSCT with no acute graft versus host disease (aGVHD).
IV. To evaluate blinatumomab pharmacokinetics (PK) and explore exposure-response relationships for measures of safety and effectiveness.
OUTLINE:
All patients receive Block 1 over 4 weeks.

Patients with central nervous system (CNS) 1 or CNS2 also receive methotrexate IT on day 8. Patients with CNS3 (including isolated CNS relapse) also receive methotrexate IT, hydrocortisone IT, and cytarabine IT on days 8, 15, and 22. High risk and intermediate risk patients are then assigned to randomization R1. Low risk patients are assigned to randomization R2.
RANDOMIZATION R1 (HR and IR patients): Patients are randomized to 1 of 2 treatment arms. Effective 09/18/2019, HR/IR patients not yet randomized are not eligible for post-Induction therapy on AALL1331 and will be removed from protocol therapy. Patients receiving therapy on Arm A prior to Amendment #10A who have not yet received day 22 treatment on Block 3 will be offered the opportunity to cross over to Arm B to receive blinatumomab.
ARM A: Patients receive Block 2 over 4 weeks, Block 3 over 4 weeks, and then undergo allogeneic HSCT if eligible. Patients with persistent testicular involvement after Block 1 receive testicular radiation during the Block 2.
ARM B: Patients receive Blinatumomab Block 1 over 5 weeks, Blinatumomab Block 2 over 5 weeks, and then undergo allogeneic HSCT if eligible. Patients with persistent testicular involvement after Block 1 receive testicular radiation during the first block of blinatumomab.
RANDOMIZATION R2 (LR patients): LR patients are randomized to 1 of 2 treatment arms.
ARM C: Patients receive Block 2 over 4 weeks, Block 3 over 4 weeks, Continuation 1 over 8 weeks, Continuation 2 over 8 weeks, and then Maintenance. CNS3 patients receive chemoradiation post-Maintenance Cycle 1. Patients with persistent testicular involvement after Block 1 receive testicular radiation during Block 2.
ARM D: Patients receive Block 2 over 4 weeks, Blinatumomab Cycle 1 over 5 weeks, Continuation 1 over 8 weeks, Blinatumomab Cycle 2 over 5 weeks, Continuation 2 over 8 weeks, Blinatumomab Cycle 3 over 5 weeks, and then Maintenance. CNS3 patients receive chemoradiation post Maintenance Cycle 1. Patients with persistent testicular involvement after Block 1 receive testicular radiation during Block 2.
BLOCK 2: Patients receive dexamethasone PO BID or IV on days 1-5; vincristine sulfate IV over 1 minute on day 1; methotrexate IV over 36 hours on day 8; leucovorin calcium IV or PO on days 10-11; pegaspargase IV over 1-2 hours on day 9 or 10; cyclophosphamide IV over 15-30 minutes on days 15-19; and etoposide IV over 1-2 hours on days 15-19. Patients with CNS1 or CNS2 also receive methotrexate IT on day 8. Patients with CNS3 also receive methotrexate IT, hydrocortisone IT, and cytarabine IT on days 8 and 22.
BLOCK 3: Patients receive dexamethasone PO BID or IV on days 1-5; vincristine sulfate IV over 1 minute on day 1; cytarabine IV over 3 hours every 12 hours on days 1, 2, 8, and 9; asparaginase intramuscularly (IM) or IV over 1 hour on days 2, 4, 9, 11, and 23; methotrexate IT on day 1and IV over 36 hours on day 22; leucovorin calcium PO or IV on days 24-25.

What is being measured
The primary outcome is the main question the study is designed to answer.
Disease Free Survival (DFS) of High-risk (HR) and Intermediate-risk (IR) Relapse Patients
DFS rates of HR and IR relapse B-ALL patients who are randomized following Induction Block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR Randomization). DFS is calculated as the time from randomization to date of first event (treatment failure, relapse, second malignancy, remission death) or date of last contact. Two-year DFS estimates will be calculated from date of randomization for both Arm A and Arm B. Two-sided 95% confidence intervals will be calculated.
Measured: Up to 2 years from date of randomization
Disease Free Survival (DFS) of Low Risk (LR) Relapse Patients
DFS rates of LR relapse B-ALL patients who are randomized following Block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR Randomization). DFS is calculated as the time from randomization to date of first event (relapse, second malignancy, remission death) or date of last contact. Three-year DFS estimates will be calculated from date of randomization for both Arm C and Arm D. Two-sided 95% confidence intervals will be calculated.
Measured: Up to 3 years from date of randomization

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 blinatumomab works compared with standard combination chemotherapy in treating patients with B-cell acute lymphoblastic leukemia that has returned after a period of improvement (relapsed). Immunotherapy with blinatumomab may allow the body's immune system to attack and destroy some types of leukemia cells. It is not yet known whether blinatumomab is more effective than standard combination chemotherapy in treating relapsed B-cell acute lymphoblastic leukemia.
Detailed description
PRIMARY OBJECTIVES:
- To compare disease free survival (DFS) of high-risk (HR) and intermediate-risk (IR) relapse B-cell acute lymphoblastic leukemia (B-ALL) patients who are randomized following induction block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR randomization) as a part of a treatment regimen prior to allogeneic bone marrow transplantation. (Closed to enrollment effective September 18, 2019) II. To compare the DFS of low risk (LR) relapse B-ALL patients who are randomized following block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR randomization). (Closed to enrollment effective September 30, 2019)
SECONDARY OBJECTIVES:
- To compare overall survival (OS) of HR and IR relapse B-ALL patients who are randomized following induction block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR randomization). (Closed to enrollment effective September 18, 2019) II. To compare OS of LR relapse B-ALL patients who are randomized following block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR randomization).
EXPLORATORY OBJECTIVES:
- To compare the rates of minimal residual disease (MRD) >= 0.01% at the end of block 2 and block 3 for HR and IR relapse B-ALL patients in HR/IR randomization.
II. To estimate, for treatment failure (TF) patients not previously receiving blinatumomab, the hematologic complete remission rate (CR), rate of MRD < 0.01%, and proportion able to proceed to hematopoietic stem cell transplant (HSCT) in CR after treatment with blinatumomab.
III. To assess the feasibility and safety of rapid taper of immune suppression for the subset of HSCT patients with MRD >= 0.01% pre- and/or post-HSCT with no acute graft versus host disease (aGVHD).
IV. To evaluate blinatumomab pharmacokinetics (PK) and explore exposure-response relationships for measures of safety and effectiveness.

Primary outcome
Disease Free Survival (DFS) of High-risk (HR) and Intermediate-risk (IR) Relapse Patients
Time frame: Up to 2 years from date of randomization
DFS rates of HR and IR relapse B-ALL patients who are randomized following Induction Block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR Randomization). DFS is calculated as the time from randomization to date of first event (treatment failure, relapse, second malignancy, remission death) or date of last contact. Two-year DFS estimates will be calculated from date of randomization for both Arm A and Arm B. Two-sided 95% confidence intervals will be calculated.
Disease Free Survival (DFS) of Low Risk (LR) Relapse Patients
Time frame: Up to 3 years from date of randomization
DFS rates of LR relapse B-ALL patients who are randomized following Block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR Randomization). DFS is calculated as the time from randomization to date of first event (relapse, second malignancy, remission death) or date of last contact. Three-year DFS estimates will be calculated from date of randomization for both Arm C and Arm D. Two-sided 95% confidence intervals will be calculated.
2 secondary outcomes
Overall Survival (OS) of HR and IR Relapse Patients
Time frame: Up to 2 years from date of randomization
Overall Survival (OS) of LR Relapse Patients
Time frame: Up to 3 years from date of randomization

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Allogeneic Hematopoietic Stem Cell Transplantation, Asparaginase and Blinatumomab in people with Recurrent B Acute Lymphoblastic Leukemia, run by National Cancer Institute (NCI) at 186 sites in 5 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 22 inclusion and 13 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 21 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 186 sites in United States, Canada, Puerto Rico, Australia, New Zealand. 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?
Yes. Results are posted in the registry (first posted 6 Dec 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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 High-risk (HR) and Intermediate-risk (IR) Relapse Patients (time frame: Up to 2 years from date of randomization). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02101853, which also lists 3 linked publications.
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 21 Oct 2026.
