Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Improvement of CR2 rates after induction with ALL R3 with bortezomib versus without bortezomib in HR relapsed ALL patients ;Secondary Objective: Improvement of EFS and OS rates Improvement of MRD reduction after induction with bortezomib versus without bortezomib Improvement of MRD load prior to SCT Increasing the proportion of HR patients reaching SCT Prognostic relevance of MRD pre SCT Improvement of CR2 and/or MRD rates during consolidation Toxicity of induction with bortezomib versus without bortezomib ;Primary end point(s): Randomized induction trial: Improvement of CR2 rates with standard chemotherapy + Bortezomib (Arm B) quantified by cytology compared with standard chemotherapy (Arm A);Timepoint(s) of evaluation of this end point: Primary endpoint will be evaluated at week 5 after induction. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Improvement of three years EFS and OS, rate of patients reaching HSCT, MRD rates post induction and pre-HSCT, prognostic relevance of MRD pre HSCT, CR2 and MRD rates during consolidation, toxicity of randomized arms;Timepoint(s) of evaluation of this end point: - EFS, OS: three years after recruitment is completed - toxicity: together with the primary endpoint - MRD rates: 9 weeks after primary endpoint | — |
