Universal premedication and therapeutic drug monitoring for asparaginase‐based therapy prevents infusion‐associated acute adverse events and drug substitutions

Background Asparaginase is a critical component of lymphoblastic leukemia therapy, with intravenous pegaspargase (PEG) as the current standard product. Acute adverse events (aAEs) during PEG infusion are difficult to interpret, representing a mix of drug‐inactivating hypersensitivity and noninactivating reactions.
