Hemlibra in Mild Hemophilia A

This is a single arm, phase 4, prospective, open-label, United States single-center study to determine the hemostatic characteristics of Hemlibra (emicizumab) as measured by coagulation laboratory parameters in the mild hemophilia A male patient population with endogenous altered FVIII (baseline FVIII activity of \>5% to 30%). The safety and hemostatic efficacy of Hemlibra (emicizumab) in this patient population will be investigated. Secondary outcomes will assess changes in joint health and quality of life in treated patients.
