Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are infants under one year old with newly diagnosed KMT2A-rearranged acute lymphoblastic leukemia or mixed phenotype acute leukemia.
✕Probably not a fit
Patients older than one year or those with KMT2A-germline leukemia or T-ALL will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This treatment protocol involves administering blinatumomab to infants under one year old diagnosed with KMT2A-rearranged acute lymphoblastic leukemia or mixed phenotype acute leukemia. Eligible infants will receive one cycle of blinatumomab following induction therapy, with further treatment based on their response. Medium risk patients may receive additional cycles or be treated according to standard protocols, while high risk patients may qualify for stem cell transplantation if they achieve minimal residual disease negativity. The study aims to improve treatment outcomes for this vulnerable population.
Why it matters
Potential benefit: If successful, this treatment could significantly improve survival rates and outcomes for infants with aggressive forms of leukemia.
How similar studies have gone: Other studies have shown promise with blinatumomab in treating acute lymphoblastic leukemia, suggesting potential for success in this specific population.

Inclusion Criteria: 1. Patients with newly diagnosed B- precursor ALL or B-cell MPAL (single lineage) according to the WHO classification of tumours of haematopoietic and lymphoid tissues (revised 4th edition 2017), with KMT2A-rearrangement. 2. ≤ 365 days of age at the time of diagnosis of ALL. 3. Written informed consent of the parent(s) or other legally authorized guardian of the patient according to local law and regulations. Exclusion criteria for blinatumomab: 1. KMT2A-wildtype patients. 2. Multilineage MPAL 3. T-ALL. 4. Age \> 365 days at the time of diagnosis. 5. Down syndrome. 6. Relapsed ALL. 7. Treatment with systemic corticosteroids (equivalent prednisone \>10 mg/m2/day) for more than one week and/or any chemotherapeutic agent in the 4-week interval prior to diagnosis. Patients who received corticosteroids by aerosol are eligible for the study. If exclusion criteria for blinatumomab are met, the patient should be treated according to the protocol but without blinatumomab.
