Machine Learning-Based Signal Detection and Prediction Modeling of Gastrointestinal Adverse Events in GLP-1 Receptor Agonists Using FAERS Data
Post-marketing surveillance of adverse events in real-world settings is a key process in drug safety management, and signal detection through spontaneous reporting systems provides critical evidence for regulatoryscientific decision-making. This study analyzed GLP-1 Receptor Agonists (GLP-1 RAs) class-related adverse event signals using the FDA Adverse Event Reporting System (FAERS) and identified factors influencing their formation. FAERS data from the second quarter of 2021 to the third quarter of 2025 were analyzed using disproportionality metrics (PRR, ROR, IC). The exposure group included all GLP-1 RA class drugs, and the comparator group comprised non-GLP-1 receptor agonists used for diabetes and obesity. Detected signals were categorized by MedDRA System Organ Class (SOC), and machine learning models (Random Forest (RF), XGBoost) were applied to identify predictors and contextual patterns of gastrointestinal (GI) adverse events. Signal detection results showed that GI disorders were frequently reported in the exposure group (a=211,797), with strong signals (ROR 2.94 [95% CI: 2.92–2.97]. The XGBoost and RF models achieved a high AUROC of 0.926 and 0.929, respectively, identifying patient age (45-64 years), seriousness, and reporter type as major predictors of GI-related signals. This suggests that GI adverse event reporting may be associated with specific reporting contexts and demographics, such as ‘patient age (45-64 years)’ and ‘seriousness’. The model's input features could predict whether a report was for a GI event with 92.9% accuracy. This study demonstrates the practical applicability of regulatory-scientific analytics, showing that combining machine learning with spontaneous reporting data enhances the accuracy and efficiency of post-marketing signal detection and provides stronger evidence for pharmacovigilance and risk management.
