Glucarpidase (CPG2) Effect on Severe Delayed Methotrexate-clearance in Children Treated Wih High-dose Methotrexate in Acute Lymphoblastic Leukemia (ALL) (NOPHOCPG2)
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.

|Official Title:||Glucarpidase (CPG2) Effect on Severe Delayed Methotrexate-clearance in Children Treated With High-dose Methotrexate in Acute Lymphoblastic Leukemia (ALL)|
- 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 ] [ Designated as safety issue: Yes ]
- Evaluate time at hospital and health costs [ Time Frame: 6 years ] [ Designated as safety issue: No ]
|Study Start Date:||January 2011|
|Estimated Study Completion Date:||June 2017|
|Estimated Primary Completion Date:||June 2017 (Final data collection date for primary outcome measure)|
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 > 20 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.
