Brief Title  ICMJE A Study of Fitusiran (ALN-AT3SC) in Severe Hemophilia A and B Patients With Inhibitors
Official Title  ICMJE ATLAS-INH: A Phase 3 Study to Evaluate the Efficacy and Safety of Fitusiran in Patients With Hemophilia A or B, With Inhibitory Antibodies to Factor VIII or IX
Brief Summary The purpose of this study is to determine the frequency of bleeding episodes in patients receiving fitusiran as prophylactic treatment of hemophilia compared with patients who are assigned to continue with their regular medication. In addition, the study will assess safety, quality of life, pharmacodynamics (PD), and pharmacokinetics (PK).
