| アブストラクト | BACKGROUND: Ravulizumab is a long-acting C5 complement inhibitor that provides sustained suppression of the complement pathway. It is currently approved by the US Food and Drug Administration (FDA) for the treatment of generalized myasthenia gravis, paroxysmal nocturnal hemoglobinuria, and atypical hemolytic uremic syndrome. With its increasing clinical use, concerns regarding Ravulizumab-associated adverse drug reactions have grown. METHODS: This study utilized a dataset extracted from the Adverse Event Reporting System (FAERS) database, comprising adverse event reports from the fourth quarter of 2018 to the second quarter of 2025. Four distinct disproportionality analysis methods-the Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Multi-item Gamma Poisson Shrinker (MGPS), and Bayesian Confidence Propagation Neural Network (BCPNN)-were applied. Additionally, the time-to-onset profile of adverse events was assessed using the Weibull distribution model. RESULTS: A total of 9,090 adverse event reports associated with ravulizumab were included in this analysis. Commonly reported adverse events included fatigue, asthenia, headache, malaise, dyspnea, back pain, feeling abnormal, and diplopia. Furthermore, potential adverse events not listed on the drug label were identified, such as anemia, dysphagia, urinary tract infection, and somnolence. CONCLUSION: This investigation identified several adverse events associated with ravulizumab and revealed potential adverse reaction signals that were not previously recognized. Healthcare providers may consider these safety signals to more comprehensively assess potential risks in patients during clinical practice. |
