Efficacia di Atenativ in pazienti con deficit congenito di antitrombina sottoposti a intervento chirurgico o parto

25 settembre 2026 aggiornato da: Octapharma

Uno studio di fase 3 multicentrico, prospettico, in aperto, non controllato per valutare l'efficacia, la sicurezza e la farmacocinetica di Atenativ in pazienti con deficit congenito di antitrombina sottoposti a intervento chirurgico o al parto

The goal of this study is to assess the incidence of the composite of thrombotic events (TEs) and thromboembolic events (TEEs) in patients with congenital antithrombin deficiency under when they receive Atenativ for surgical procedures or parturition.
