Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Blinatumomab
Treatment: Drugs - Blinatumomab

Other: Medium Risk (MR) - Subject is defined as MR if \> 6months of age at diagnosis, OR \< 6 months of age with White Blood cell Count (WBC) \< 300 at diagnosis and good prednisone response. Subject gets 1st cycle of blinatumomab. If MRD is \>0.01%, after 1st cycle of blinatumomab, subject will be allocated to HR treatment from that phase, and will be eligible for HSCT. If MRD is undetectable or \< 0.01% after the 1st cycle of blinatumomab (TP2) patient will be eligible for replacement of MARMA by 2nd cycle of blinatumomab after receipt of lymphoid style consolidation (Protocol IB) or of myeloid style consolidation (ADE/MAE).

Other: High risk (HR) - Subject is defined as HR if \< 6 months of age with WBC \> 300 at diagnosis OR poor prednisone response. Also MR patients with end of induction MRD = 1%, or MRD \> 0.01% after the 1st cycle of blinatumomab, will be allocated to HR treatment. Subject gets 1 cycle of blinatumomab.

Thereafter patient is eligible for hematopoietic stem cell transplantation (HSCT) with or without experimental therapy in an investigational window.


Treatment: Drugs: Blinatumomab
1st cycle: 15 µg/m2/day as a 4 week continuous IV infusion for patients with a M1 marrow. For patients with a M2/M3 marrow a step-dosing strategy is required with a dose of 5 µg/m2/day in week 1 followed by 15 µg/m2/day in weeks 2, 3, and 4.

Treatment: Drugs: Blinatumomab
2nd cycle: 15 µg/m2/day as a 4 week continuous iv infusion

2. =365 days of age at time of diagnosis of ALL
3. Written informed consent of the parents or other legally authorized guardian of the patient according to local law and regulations.
Minimum age

Key exclusion criteria
1. KMT2A-germline patients
2. T-ALL
3. Age > 365 days at the time of diagnosis
4. Relapsed ALL
5. 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.

Additional exclusion criteria for blinatumomab:

1. CD19 negative B-precursor ALL at diagnosis
2. CNS involvement (CNS2/CNS3 status) at the EOI. Patients with CNS disease at the time of diagnosis are eligible if CNS1 status is achieved prior to the start of the first blinatumomab cycle (lumbar puncture at ~day 33 of induction).
3. Proven hypersensitivity to the active substance or any of the excipients in blinatumomab.
4. Patients who have received a live vaccine 28 days prior to blinatumomab administration or plan to receive a live vaccine prior to B-cell recovery after the last dose of blinatumomab.
