E.2 Objective of the trial |
E.2.1 | Main objective of the trial |

|
|
E.2.2 | Secondary objectives of the trial |
1. Does Arm B clear disease during induction chemotherapy more quickly than Arm A? 2. Do more patients on Arm B undergo SCT than in Arm A? 3. Is Arm B more toxic than Arm A? 4. Is toxicity greater in patients receiving Epratuzumab? 5. Does epratuzumab lower MRD levels? 6. Does Arm B result in more MRD negativity before SCT than in Arm A? 7. Does epratuzumab affect the rate of MRD negativity before SCT? 8. Compare the pharmacokinetics of epratuzumab in Arm A and B

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Morphologically confirmed diagnosis of 1st relapsed precursor B-cell or T-cell ALL • Children less than 18 years of age at inclusion • Meeting SR criteria: late isolated or late/early combined B Cell Precursor BM relapse, any late/early isolated extramedullary relapse • Patient enrolled in a participating centre • Written informed consent • Start of treatment falling into the study period • No participation in other clinical trials 30 days prior to study enrolment that interfere with this protocol, except trials for primary ALL
Inclusion criteria specific for the epratuzumab randomization: • Precursor B-cell immunophenotype. A specific CD22 expression level is not required • M1 or M2 status of the bone marrow after induction |
|
E.4 | Principal exclusion criteria |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome of Event free survival (EFS1) for the ALLR3/ALL-REZ BFM 2002 randomisation is defined as the time from randomisation to the first of induction failure, relapse, death from any cause or second malignancy, or is censored at the date of last follow-up. Note that SCT is not considered as event and is also not censored in the EFS1 analyses.
The primary outcome of Event free survival (EFS2) for the epratuzumab/no eprratuzumab randomisation is defined as the time from randomisation to the first of persisting non-response, progression, death from any cause or second malignancy, or is censored at the date of last follow-up. Note that for SR2 analysis, M0 or M3 patients at the start of consolidation and induction failures will be off study and not included in the analysis. Note that SCT is not considered as event and is also not censored in the EFS2 analyses.
