Glucarpidase Effect on Severe Delayed HDM-clearance in Children Treated With High-dose Mtx in ALL

Early intervention in children and adolescents who experience delayed MTX-clearance and renal dysfunction in ALL treatments with the enzyme Glucarpidase which rapidly hydrolyses MTX to non-toxic metabolites to avoid life threatening complications.

About this study

The NOPHO ALL-2008 protocol is a treatment and research protocol that aims to improve the overall outcome of Nordic children and adolescents with ALL in comparison with the ALL-2000 protocol and with the aim to reduce and prevent toxic treatment complications with high-dose methotrexate (HD-MTX).

The specific and primary objectives of the randomized study is:

  • Early intervention in children and adolescents who experience delayed MTX-clearance and renal dysfunction with the enzyme Glucarpidase which rapidly hydrolyses MTX to non-toxic metabolites and lowers the serum concentration to avoid life threatening complications. Glucarpidase should be given if the 24 hour levels of MTX is > 250 µM, 36 hour levels > 30 µM or 42 hours levels > 10 µM together with a reduced kidney function. Glucarpidase treatment should take place within 48 hours from the start of HD-MTX treatment.
  • To evaluate if the early intervention with Glucarpidase reduce the number of days the patients have to stay at the hospital.
  • Evaluate the reduction of health costs of early intervention in patients with delayed MTX-clearance and renal dysfunction.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Children and adolescents who experience delayed MTX-clearance and renal dysfunction during high-dose methotrexate treatment in NOPHO ALL-2008.

Exclusion criteria

Children and adolescents with earlier anaphylactic reaction to Glucarpidase. Pregnant patients.

Treatment and study plan

glucarpidase

Drug

Patients treated with Glucarpidase if the 24 hour levels of MTX is >250 µM, 36 hour levels >30 µM or 42 hours levels >10 µM together with a reduced kidney function will be compared with patients in just below the tricking values.

Primary outcomes

  1. Number of Participants With Adverse Event to HD-MTX Treatment in NOPHO ALL-2008 as a Measure of Toxic Mtx Concentrations in Blood, Nephrotoxicity, Hepatotoxicity, Mucositis, MTX Elimination Time and Permanent Kidney Damage.

    Time frame: 6 years 6 months

    Glucarpidase was used in case of predefined toxic MTX values at defined time points and/or in combination with decreased renal function.

    A total of 47 patients of the 1286 ALL-patients included in the protocol (3.7 %) were treated with Glucarpidase.
