Regulatory Determination / Use
Cases of cutaneous small-vessel vasculitis (CSVV) associated with direct oral anticoagulants (DOACs) were reported in DOAC premarket trials and to the FDA Adverse Events Reporting System (FAERS) post approval. FDA conducted a study in Sentinel to characterize CSVV cases among patients with atrial fibrillation treated with DOACs. Additional studies in Sentinel explored incidence rates for DOACs, warfarin, and allopurinol as positive control and compared adjusted CSVV risk in new users of DOACs and warfarin. No statistically significant differential CSVV risk was observed among new users of DOACs and warfarin. FDA did not take regulatory action at this time, based on available information.
