| アブストラクト | OBJECTIVE: PEGylation is commonly used to optimize pharmacological properties and improve the clinical response of drugs. Due to the inherent toxicity of polyethylene glycol (PEG) and pharmacological changes induced by PEGylation, the safety may be altered and required to be explored. This study explored the adverse events (AEs) associated with PEGylation by comparing pharmacovigilance data of PEGylated and parent drugs. MATERIALS AND METHODS: We conducted a disproportionality analysis of spontaneous reports associated with PEGylated and corresponding parent medications from the FDA Adverse Event Reporting System database recorded between the 1(st) quarter of 2004 and the 4(th) quarter of 2018 at the level of preferred terms (PTs) and standard MedDRA queries (SMQs), respectively. The AEs probably different in risk due to changed pharmacological effects and inherent toxicity of PEG were analyzed. RESULTS: A total of 259,428 cases associated to six drug pairs (filgrastim, asparaginase, interferon alpha-2a, interferon alpha-2b,interferon beta-1a, and liposomal doxorubicin) were collected. Although 95% of PTs were comparable between the two groups, PTs of deep vein thrombosis, pancreatitis acute, diabetes mellitus, liver disorder, disorientation, aphasia and infection, and SMQ of embolic and thrombotic events were significantly alleviated by PEGylation. No PT was significantly enhanced by PEGylation. CONCLUSION: The pharmacovigilance profiles of PEGylated and non-PEGylated agents were similar. Further clinical assessment is required to validate the pharmacovigilance data. |
