Brief Summary:

Pegylated-asparaginase (PEG-ASP) is an important part of the treatment of childhood acute lymphoblastic leukaemia (ALL). Unfortunately 13% of patients develops allergy and further treatment is impossible. Furthermore, 6% of patients have developed antibodies (silent inactivation) and have no effect of the PEG-ASP treatment. Truncated asparaginase therapy is associated with inferior event-free survival outcomes, in particular relapse in central nervous system (CNS).

Eryaspase is a new formulation of asparaginase encapsulated in erythrocytes. The erythrocyte membrane protects asparaginase against fast degradation and elimination processes. The encapsulation eliminates the direct somatic contact, and it is hypothesized that this provides the potential to prolong the activity of the enzyme and reduce toxicities.

Layout table for eligibility information
Ages Eligible for Study:   1 Year to 45 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Male or female aged 1-45 years at diagnosis of ALL
  2. First line non-high risk (HR) ALL patients enrolled in the treatment protocol Nordic Society of pediatric hematology and oncology (NOPHO) ALL 2008 including PEG-asparaginase regimen
  3. Documented hypersensitivity reaction to PEG-asparaginase with either:

    Clinical allergy to PEG-Asparaginase (mild/severe) OR Serum asparaginase activity below the lower level of quantification.

  4. Karnofsky/Lansky score ≥ 50.
  5. Ability to understand, and willingness to sign, a written informed consent document and to comply with the scheduled visits, treatment plans, laboratory tests, and other study procedures. For patients under 18 years of age, either both parents or the legally appointed representatives will need to provide consent.

Exclusion Criteria:

  1. Philadelphia chromosome positive ALL.
  2. Participation in another clinical trial interfering with the study therapy with exception of NOPHO ALL-2008. Patients can participate in other clinical trials not interfering with the study drug. In case of doubt this is assessed by the PI.
  3. Uncontrolled intercurrent illness including, but not limited to, patients receiving combination antiretroviral therapy or patients with severe or systemic infection, or psychiatric illness/social situations that would limit compliance with study requirements.
  4. Other severe acute/chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the patient inappropriate for entry into this study.
  5. Pregnant or lactating females (serum human chorionic gonadotropin pregnancy test at screening). Use of a highly effective contraceptive measure in women of child-bearing potential and sexually active girls that are of child-bearing potential is required (contraceptive measures are specified in section 6.0).
  6. Inadequate organ functions, which prohibit further asparaginase administration;

    1. History of pancreatitis
    2. History of serious hemorrhage or serious thrombosis with prior asparaginase therapy
    3. Severe hepatic impairment at the time of administration (bilirubin >3 times ULN, transaminases >10 times ULN)
    4. Pre-existing known coagulopathy (e.g. haemophilia)
  7. History of grade 3 or higher transfusion reactions or any contraindication to receive blood transfusion. Presence of specific anti-erythrocytes antibodies (auto-antibodies or anti-public antibodies) preventing from getting a compatible packed Red Blood Cells for the patient.
  8. Patient under concomitant treatment likely to cause hemolysis.
