Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 51 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • 3.1.1Confirmed diagnosis of Philadelphia chromosome-negative acute lymphoblastic leukemia.
  • Diagnosis should be made by peripheral blood, bone marrow aspirate, bone marrow biopsy, or tissue biopsy demonstrating ≥25% involvement by lymphoblasts, with flow cytometry or immunohistochemistry confirming B-ALL or T-ALL.
  • o Participants with B-cell and T-cell lymphoblastic lymphoma are eligible regardless of bone marrow involvement Participants with mixed phenotype acute leukemia (MPAL) ARE eligible, if an ALL regimen is felt to be most appropriate treatment.
  • Participants with CNS leukemia ARE eligible. 3.1.2 Allowed prior therapy:
  • Corticosteroids, hydroxyurea, all-trans retinoic acid (ATRA).
  • IT chemotherapy.
Show all 10Show fewer
  • Emergent radiation therapy or leukapheresis for life threatening complications.
  • One cycle of prior chemotherapy (i.e. an induction cycle given at another institution and participant transfers care for post-induction treatment; OR a participant does not meet eligibility prior to induction but does meet eligibility after remission induction).
  • 3.1.3 Age 18.00 - 50.99 years 3.1.4 Direct bilirubin <1.4 mg/dL (total bilirubin < 1.4 mg/dL is acceptable). 3.1.5 Willingness to use effective means of birth control. The effects of chemotherapy on the developing human fetus are unknown. For this reason and because therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of study.
  • 3.1.6 Ability to understand and the willingness to sign a written informed consent document.

Who cannot join

  • Philadelphia chromosome-positive / BCR::ABL1 fusion 3.2.2 Participants with mature B-cell (Burkitt's) ALL. Mature B-cell ALL is defined by the presence of surface immunoglobulin AND any of the following: t(8;14)(q24;q32), t(8;22), t(2;8), or c-myc-gene rearrangement by FISH, PCR or other testing. [FISH/PCR testing for c-myc rearrangements is not required prior to study entry, but it is suggested for participants with surface immunoglobulin expression or L3 morphology]. 3.2.3 Participants with acute undifferentiated leukemia. 3.2.4 Participants receiving any other investigational agent for this condition.
  • 3.2.5 Uncontrolled intercurrent illness including but not limited to ongoing infection with vital sign instability (hypotension, respiratory insufficiency), life-threatening acute tumor lysis syndrome (e.g., with renal failure), symptomatic congestive heart failure, cardiac arrhythmia, intracranial or other uncontrolled bleeding. Circumstances that may significantly interfere with a participant's ability to safely comply with study procedures, such as attend scheduled study visits, adhere to treatment protocols, or complete study assessments. These include a lack of reliable transportation, unstable housing, or psychiatric illness, but reasonable attempts should be made to overcome these circumstances, including but not limited to identifying sponsor, institutional, or thirdparty financial or social support as well as psychiatric consultation for objective assessment. 3.2.6 Sexually active participants of reproductive potential who have not agreed to use an effective contraceptive method for the duration of study participation are ineligible.
  • 3.2.7 Pregnant women are excluded from this study because many of the agents used on this protocol have potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with these chemotherapy agents, breastfeeding should be discontinued if the mother is enrolled.

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 10 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 17 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Contact Marlise R Luskin, MD, MSCE (617-632-1906, marlise_luskin@dfci.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Treatment Completion Rate Through Time Point 3 (TP3) (time frame: Timeframe for TP3 depends on disease immunophenotype. Participants with CD19-positive B-ALL, TP3 occurs at the end of Blinatumomab Cycle 2 on Day 28 (130 days from study start). For participants with T-cell ALL or those who do not receive blinatum). 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 17 Aug 2026.
