Abstract in brief

  • Andexanet Alfa effectively reverses the anticoagulant effects of factor Xa inhibitors like apixaban and rivaroxaban, primarily by significantly reducing antifactor Xa activity and unbound drug concentrations.
  • The reversal occurs rapidly, with thrombin generation restored within minutes, and effects are sustained through bolus and infusion methods without serious adverse or thrombotic events.
  • Some transient increases in blood clotting markers were observed but resolved within days, indicating that andexanet is a promising agent for managing bleeding complications related to factor Xa inhibitors.

In the ANNEXA-A and -R studies, andexanet alfa (AA) reduced anti-FXa activity and restored thrombin generation in healthy older volunteers Maximal effect was noted within 2-5 min of bolus and sustained throughout the infusion https://t.co/DzXjwZhk9v 2/ https://t.co/ScMV2BrNMP
