Long-term Safety and Efficacy of Efanesoctocog Alfa (BIVV001) in Previously Treated Patients With Hemophilia A — XTEND-ed  

Hemophilia A Clinical Trial

Official title:
A Phase 3 Open-label, Multicenter Study of the Long-term Safety and Efficacy of Intravenous Recombinant Coagulation Factor VIII Fc-von Willebrand Factor-XTEN Fusion Protein (rFVIIIFc-VWF-XTEN; BIVV001) in Previously Treated Patients With Severe Hemophilia A

Clinical Trial Summary

Primary Objective: - To evaluate the long-term safety of BIVV001 in previously treated subjects with hemophilia A Secondary Objectives: - To evaluate the efficacy of BIVV001 as a prophylaxis treatment. - To evaluate the efficacy of BIVV001 in the treatment of bleeding episodes. - To evaluate BIVV001 consumption for prevention and treatment of bleeding episodes. - To evaluate the effect of BIVV001 prophylaxis on joint health outcomes. - To evaluate the effect of BIVV001 prophylaxis on Quality of Life (QoL) outcomes. - To evaluate the safety and tolerability of BIVV001 treatment. - To assess the PK of BIVV001 based on the one stage activated partial thromboplastin time (aPTT) and two-stage chromogenic FVIII activity assays (only applicable to Arm B). - To evaluate the efficacy of BIVV001 for perioperative management

Clinical Trial Description

Participants will receive BIVV001 once weekly for a total of at least 100 exposure days to BIVV001 (including exposure during a BIVV001 parent study, if applicable). Participants will have the opportunity to continue in this study for up to 4 years, unless BIVV001 is commercially available in their applicable participating country. ;
