Long-term efmoroctocog alfa prophylaxis improves perceived pain, mental, and physical health in patients with hemophilia A: analysis of phase III trials using patient-reported outcomes.

Background: Hemophilia-associated bleeding and resultant joint pain and mobility restrictions can predispose patients to poor health-related quality of life (HRQoL). Therefore, efficacy of a treatment needs to address more than just annualized bleed rates.

Objectives: Describe the evolution of HRQoL, pain, and activity in patients with hemophilia A, treated with efmoroctocog alfa prophylaxis.
