A Drug Monitoring Study on PEG-asparaginase Treatment in Children Diagnosed Acute Lymphoblastic Leukaemia

Aarhus University Hospital200 enrolled

Overview

Asparaginase is an important drug i the treatment of childhood leukaemia. The aim of this project is to study the pharmacokinetics, pharmacodynamics and antibody development and hypersensitivity reactions during prolonged PEG-asparaginase treatment. Study part 1) Asparaginase pharmacokinetics and pharmacodynamics during prolonged PEG-asparaginase treatment: A NOPHO ALL-2008 study Study part 2) Asparagine depletion in cerebrospinal fluid: A NOPHO ALL-2008 study Study part 3) A characterization of PEG-asparaginase hypersensitivity in children treated according to the NOPHO ALL 2008 protocol Perspectives: New knowledge about PEG-asparaginase treatment regarding dosing, dosing interval, adverse effects and EFS, which may lead to improved future therapy Patients: Children diagnosed with acute lymphoblastic leukaemia in the Nordic Countries

Outcomes

Primary Outcomes

Asparagine depletion

Blood samples and cerebrospinal fluid samples are collected at certain timepoints during 30 weeks of treatment with PEG-asparaginase. They are analyzed for asparagine, asparaginase-enzyme activity and asparaginase-antibodies.These measures tell about the effect of the drug, PEG-asparaginase.

Time frame: Up to 30 weeks of treatment
