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.

Primary Outcome Measures:
  • efficacy and toxicity combined [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
    efficacy assessed according mean duration of asparaginase activity / toxicity assessed according incidence of allergic reaction whatever the grade

Secondary Outcome Measures:
  • Molecular response rate [ Time Frame: 1 month ] [ Designated as safety issue: No ]
  • Plasma concentration of asparagine, aspartate, glutamine, glutamate and asparaginase [ Time Frame: 0,1,3,6, 9 days post-dose ] [ Designated as safety issue: No ]
  • Specific anti L-asparaginase antibodies [ Time Frame: 0,10 days post-dose ] [ Designated as safety issue: No ]
  • Event free survival [ Time Frame: 6 and 12 month ] [ Designated as safety issue: No ]
  • Relapse free survival [ Time Frame: 6 and 12 month ] [ Designated as safety issue: No ]
  • Overall survival [ Time Frame: 6 and 12 month ] [ Designated as safety issue: No ]
  • Percentage of patient with complete remission [ Time Frame: 1 month ] [ Designated as safety issue: No ]

Enrollment: 80
Study Start Date: December 2009
Estimated Study Completion Date: August 2016
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: GRASPA

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)
one injection of GRASPA 150 IU/kg at each cycle of chemotherapy
Other Name: ERY001
Active Comparator: reference L-asparaginase

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).

Drug: L-asparaginase
3 to 4 Injections of Native E.coli asparaginase 10000IU/m² (every 3 days) at each cycle of chemotherapy

Detailed Description:

This open, randomized international Phase 2/3 study will enrol patients with relapsed ALL. The co-primary endpoints were the duration of asparagine depletion < 2µmol/L and the incidence of asparaginase hypersensitivity during induction. Key secondary endpoints are complete remission (CR), minimal residual disease (MRD), event free survival (EFS) and overall survival (OS).The study was powered to detect 3-fold difference in the incidence of allergic reactions between treatments. patients will be randomized to GRASPA or to Reference L-asparaginase. Patients with history of hypersensitivity to previous L-asparaginase treatment will be treated with GRASPA (exploratory arm)
