PEGylated Asparaginase in Children with Acute Lymphoblastic Leukemia Treated within the AIEOP-BFM ALL 2009 Trial: Population Pharmacokinetics and Drug Exposure.

ABSTRACT:

Background and objectives

Focusing on pharmacokinetic-derived individual dose-intensity parameter values (DIPs), we modeled the pharmacokinetics of polyethylene glycol-conjugated asparaginase (PEG-ASNase) in all treatment phases and different trial groups of AIEOP-BFM ALL 2009.

Methods

Children with acute lymphoblastic leukemia received 1-10 weekly or biweekly repetitive doses (2500 U/m²/dose intravenously). A population pharmacokinetic (popPK) model was extended to all phases to describe the pharmacokinetics and the impact of anti-PEG- and anti-asparaginase-antibodies in the German/Czech group (2535 patients, aspartic acid β-hydroxamate (AHA) assay) and validated the model in the Italian group (1603 patients, medac asparaginase activity test (MAAT) assay).
