Adverse events associated with Atogepant: a FAERS-based pharmacovigilance analysis.

Background: Migraine, a prevalent neurovascular disorder, can significantly disrupt an individual's daily life. Atogepant (AGN-241689), an orally administered small-molecule drug classified as a calcitonin gene-related peptide receptor antagonist, is utilized for prophylactic migraine treatment. The objective of this study was to investigate adverse events (AEs) associated with atogepant through data mining in the FDA Adverse Event Reporting System (FAERS) to enhance clinical safety.

Methods: Data for atogepant were obtained from the FAERS database covering Q3 2021 through Q4 2023. Disproportionality analysis was employed to quantify relevant AEs associated with atogepant. Reported Ratio of Ratios (ROR) was utilized for identifying risk signals within the FAERS data. This methodology relies on the System Organ Class (SOC) and Preferred Terminology (PT) of the Medical Dictionary for Regulatory Activities (MedDRA).

Results: From the FAERS database, a collection of 7,991,243 reports was obtained. Among these reports, a subset of 3015 was identified as 'primary suspected (PS)' AEs specifically related to atogepant. AEs induced by atogepant were observed across 27 organ systems. A total of 48 significantly disproportionate Preferred Terminologies (PTs) meeting all four algorithms were identified.

Conclusion: Our study has identified adverse events (AEs) associated with atogepant, potentially providing crucial support for the clinical monitoring and risk identification of atogepant.
