A Randomized Phase I Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Recombinant Erwinia Asparaginase (JZP-458) in Healthy Adult Volunteers.

ABSTRACT: L-asparaginase has been an important component of acute lymphoblastic leukemia (ALL) therapy for over 40 years, and is standard therapy during ALL induction and consolidation treatment. L-asparaginases are immunogenic and can induce hypersensitivity reactions; inability to receive asparaginase has been associated with poor patient outcomes. There are L-asparaginases of varied bacterial origins, with the most commonly used being Escherichia coli (E. coli); therefore, to ensure that patients who develop hypersensitivity to E. coli-derived asparaginases receive an adequate therapeutic course, alternative preparations are warranted. JZP-458 is a recombinant Erwinia asparaginase produced using a novel Pseudomonas fluorescens expression platform that yields an enzyme with no immunologic cross-re
