Comprehensive analysis of sparsentan-related adverse events: latest insights from VigiAccess and FAERS.

backgroundSparsentan represents a major advancement in the treatment of proteinuric kidney diseases, offering a promising option to improve patient outcomes and slow disease progression. Evaluation of its safety profile is essential to support its long-term integration into clinical practice.

methodsThis study employed a retrospective descriptive analysis combined with four advanced statistical methods to evaluate adverse events related to sparsentan. The data, sourced from the WHO's VigiAccess database, was queried in November 2024 to retrieve adverse event reports associated with sparsentan.
