| Main Objective: Phase II: Assessment of the efficacy and safety of clofarabine combined with PEG-ASP in high-risk ALL patients Phase III: MRD based randomized assessment of the cytotoxic efficacy of clofarabine compared to high dose-cytarabine each in combination with PEG-ASP During the entire trial duration: Evaluation of the rate of severe infectious complications after ADR versus DNR in re-induction;Secondary Objective: 1st. Comparison of safety profiles of clofarabine/PEG-ASP versus high-dose cytarabine/PEG-ASP 2nd. MRD-based comparison of the efficacy in the high-risk treatment arm between clofarabine/PEG-ASP and high-dose cytarabine/PEG-ASP respectively, and the historical control group MTX/CYC/ASP in protocol COALL 07-03 3rd. Assessment of the impact of MRD-based stratification in COALL 09 on overall and event-free survival compared to historical COALL control groups 4th. Assessment of the overall survival and of the event free survival in a randomized comparison of the therapy arms clofarabine/asparaginase versus high dose-cytarabine in protocol COALL 08-09;Primary end point(s): Trial phase II: assessment and evaluation of the efficacy and safety of the combination treatment clofarabine/PEG-asparaginase in high-risk ALL patients compared to the historical collective with Hidac/PEG-ASP. The following trial phase III: comparison of the efficacies of clofarabine versus high-dose cytarabine. The primary end point will be determined in patients, who reveal a measurable MRD load before intensification therapy. | — |
