Trial design

Randomised, comparators: standard extended consolidation (standard of care consolidation) vs addition of proteasome inhibitor bortezomib during extended consolidation (r-ehr); two cycles post-consolidation immunotherapy with blinatumomab (15 μg/m²/d for 28 days per cycle) plus 4 doses intrathecal methotrexate vs two conventional highly intensive chemotherapy courses (r-hr); one cycle post-reintensification blinatumomab (15 μg/m²/d for 28 days) vs 4 weeks of standard maintenance therapy (r-mr); extension of consolidation with increased cumulative doses of cyclophosphamide, cytarabine and 6-mercaptopurine by 50% vs standard consolidation (r-t).-controlled Phase III trial in Italy, Slovakia, Austria and others.

Vulnerable Population
Vulnerable population: children and adolescents (<18 years) are included; written informed consent is required. Age-specific subject information sheets and informed consent/assent forms are provided (parents/legal representative consent forms and separate ICF/SIS for adolescents and for age groups 8-11, 12-15, 16-17, and 18 or greater). There is a re-consent document for participants upon reaching adulthood (re-consent on reaching majority). Country-specific ICF/SIS documents exist (Italy, Germany, Slovakia, Austria, Czechia).

Inclusion criteria

  • {"criterion_text":"- newly diagnosed acute lymphoblastic leukemia, from 1st September 2023 onwards only acute lymphoblastic leukemia with T-cell phenotype or\n- newly diagnosed mixed phenotype acute leukemia (MPAL) meeting one of the following criteria: • biphenotypic with a dominant T or B lineage assignment,from 1st September 2023 onwards only those with a dominant T lineage assignment, •bilineal either with a dominant lymphoblastic (from 1st September 2023 onwards only T lymphoblastic) population or if another reasonable rationale exists to treat the patient with an ALL-based therapy regimen\n- newly diagnosed acute undifferentiated leukemia\n- age < 18 years (up to 17 years and 365 days) at the day of diagnosis\n- patient enrolled in a participating center\n- written informed consent to trial participation and transfer and processing of data"}

Endpoints

Primary endpoints

  • {"endpoint_text":"- For the randomized study questions, the primary endpoint will be the time from randomization until the first event defined as follows: Randomization R-eHR, R-HR and R-T: Cytomorphological or molecular non-response (resistance to protocol treatment, considered as event at day zero), relapse, second malignancy or death from any cause. This will be called EFS time.","definition_or_measurement_approach":"Time from randomization to first event (cytomorphological or molecular non-response, relapse, second malignancy, or death) — defined as EFS time for R-eHR, R-HR and R-T."}
  • {"endpoint_text":"- Randomization R-MR: Relapse, second malignancy or death from any cause. This will be called DFS time.","definition_or_measurement_approach":"Time from randomization to relapse, second malignancy or death — defined as DFS time for R-MR."}
  • {"endpoint_text":"- EFS and DFS time: end of study","definition_or_measurement_approach":"EFS and DFS times evaluated until end of study."}

Secondary endpoints

  • {"endpoint_text":"- Survival starting at the same time point as the EFS/DFS","definition_or_measurement_approach":"Overall survival measured from same timepoint as EFS/DFS."}
  • {"endpoint_text":"- Frequency and incidence of treatment-related mortality in induction or CCR","definition_or_measurement_approach":"Incidence and frequency counts of treatment-related mortality during induction or CCR phases."}
  • {"endpoint_text":"- Frequency and incidence of AE of interest and SAE in specific protocol phases, randomized arms and overall during follow-up","definition_or_measurement_approach":"Counts and rates of specified AEs and SAEs by protocol phase and treatment arm during follow-up."}
  • {"endpoint_text":"- MRD load after the randomized treatment phases (R-eHR, R-HR, R-MR and R-T)","definition_or_measurement_approach":"Measurement of MRD load after randomized treatment phases (assessed by molecular/cytomorphological MRD assays as defined in protocol)."}
  • {"endpoint_text":"- MRD load after the first/second cycle of Blinatumomab or after the HR 2'/HR 3' block (R-HR)","definition_or_measurement_approach":"MRD measured after Blinatumomab cycles or after specified HR blocks."}
  • {"endpoint_text":"- Proportion of patients with poor MRD response to the first Blinatumomab cycle (\"Blinatumomab Poor-Response\") (R HR)","definition_or_measurement_approach":"Proportion (%) of patients meeting protocol-defined criteria for poor MRD response after first Blinatumomab cycle (per protocol section referenced)."}
