Summary
Brief summary (as posted)
Asparaginase is a cornerstone in the treatment of ALL, but its utility is limited by toxicities including hypersensitivity. Clinical allergy is associated with inactivation of asparaginase by antibodies (A-Abs), which can also neutralize asparaginase without any clinical signs of hypersensitivity (silent inactivation). GRASPA improves pharmacokinetics, tolerability and maintain circulating asparaginase activity due to the protective barrier of the erythrocyte membrane. This study is run to confirm the benefit/risk profile of GRASPA at 150 IU/kg in combination with the COOPRALL regimen in adults and children patients with relapsed ALL, with or without known hypersensitivity to L-asparaginase.

- description
- Each patient randomized in GRASPA® group is to receive at least 2 and up to 10 administration of GRASPA® 150 IU/kg, in combination with standard chemotherapy (COOPRALL). GRASPA® administration takes place as below: * for induction phase: at Day 4 and D18 (F1-F2 induction ) or at D6 if Vanda induction applies (according disease severity) * for consolidation phase: at Day 6 of R2 / R1 blocks, each time block of chemotherapy is given (up to 8 cycles)

- For patient randomized in control group, reference L-asparaginase 10,000 IU/m² will be administered every 3 days intravenously, in combination with standard chemotherapy (COOPRALL). •for induction phase:at Day 4 , D7, D10, D13 (F1 block ) then at Day 18, D21, D24, D27 (of F2 Blocks). NB: administrations take place at D6, D9, D12 and D15 in case of F1-F2 Induction is replaced by VANDA (according disease severity) •for consolidation phase: at D6, D9, D12 ofR2/R1 blocks, each time block of chemotherapy is given (up to 8 cycles).
