Alglucosidase alfa for injection is used as an enzyme replacement therapy for the treatment of Pompe disease. The safety profile of alglucosidase alfa-associated adverse events requires a comprehensive evaluation. In this study, we aimed to identify drug safety alert signals and investigate the real-world safety of alglucosidase alfa to guide clinical decision making and optimize the risk-benefit balance. The adverse event reports from the first quarter of 2006 to the fourth quarter of 2023 were selected by exploring the Food and Drug Administration Adverse Event Reporting System (FAERS) database. The new and unexpected potential adverse event signals were detected using a disproportionality analysis, including the reporting odds ratio, the proportional reporting ratio, the Bayesian confidence propagation neural network, and the empirical Bayes geometric mean. Then, the Medical Dictionary for Regulatory Activities was used to systematically classify the results. After analyzing 16,945,027 adverse event reports, a total of 4326 cases of adverse events related to alglucosidase alfa were identified, spanning 27 system organ classes. A total of 359 preferred terms of adverse events for glucosidase alpha were detected. Pyrexia ranked first, followed by pneumonia, dyspnea, respiratory failure, and disease progression according to occurrence frequency. The top three system organ classes were general disorders and administration-site conditions (n = 2466), respiratory, thoracic, and mediastinal disorders (n = 1749), and infections and infestations (n = 1551). In addition to adverse effects mentioned in the product label, our study also discovered rare but high signal intensity adverse events such as chronic recurrent multifocal osteomyelitis. There are many adverse events associated with the clinical use of alglucosidase alfa, which should be closely monitored in the FAERS database. As the most effective enzyme replacement therapy for Pompe disease, it is crucial to closely monitor these adverse events. Ensuring patient safety while balancing drug effectiveness is particularly important.
