Pegaspargase versus asparaginase in adult ALL: a pharmacoeconomic assessment.

چکیده
Asparaginase is an effective treatment for patients with acute lymphocytic leukemia (ALL). Unfortunately, asparaginase therapy is associated with a high incidence of hypersensitivity reactions (up to 73%), including life-threatening anaphylaxis, and its half-life of approximately 20 hours necessitates daily administration. Pegaspargase, a modification of L-asparaginase, has a longer half-life (357 hours), a decreased incidence of hypersensitivity reactions, and when doses every 14 days, provides comparable efficacy to asparaginase; however, it is much more expensive per single-dose vial ($980.00 vs $52.38). To determine the pharmacoeconomic impact of the two agents, we conducted a cost-minimization analysis for three common adult ALL protocols. Results showed that pegaspargase was significantly less costly to payers on an inpatient or outpatient basis and warranted addition to our formulary.

For this study, 118 children with standard-risk acute lymphoblastic leukemia (ALL) were given randomized assignments to receive native or pegylated Escherichia coli asparaginase as part of induction and 2 delayed intensification phases. Patients treated with pegaspargase had more rapid clearance of lymphoblasts from day 7 and day 14 bone marrow aspirates and more prolonged asparaginase activity...
