Abstract

Introduction

Hemophilia A and B are rare bleeding disorders characterized by ineffective clot formation due to impaired thrombin generation as a result of deficiency of FVIII or FIX, respectively. Fitusiran is a subcutaneously (SC) administered investigational siRNA therapeutic targeting antithrombin to restore thrombin generation and rebalance hemostasis in people with hemophilia A or B, with or without inhibitors. Here, we present the safety and efficacy of fitusiran prophylaxis for PwHI in a phase 3 study (ATLAS-INH; NCT03417102).
