Asparaginase is an enzyme used as an antineoplastic agent primarily in the treatment of acute lymphoblastic leukemia (ALL). It works by depleting the amino acid asparagine, which leukemia cells are unable to synthesize, thereby inhibiting their growth. Asparaginase is approved and in use, especially as a part of multiagent chemotherapy protocols for pediatric and adult ALL.
Pharmacokinetics
Pharmacokinetic parameters reported for native E. coli-derived asparaginase in children with acute lymphoblastic leukemia, following intravenous administration of 6000 IU/m2.
