An Observational Study to Evaluate Physical Activity, Bleeding Incidence and Health Related Quality of Life, in Participants With Haemophilia A Without Inhibitors Receiving Standard of Care Treatment

Overview

This multicenter, non-interventional, prospective study will collect information about activity status, bleeds, health-related quality of life (HRQoL), health status, and safety in participants with moderate or severe haemophilia A without factor VIII (FVIII) inhibitors, who are being treated in accordance with normal clinical practice.

Full Title of Study: “A Multicenter, Non-Interventional Study to Evaluate Physical Activity, Bleeding Incidence and Health Related Quality of Life, in Patients With Haemophilia A Without Inhibitors Receiving Standard of Care Treatment”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: December 31, 2022

Interventions

  • Drug: Standard of Care for Haemophilia A

Clinical Trial Outcome Measures

Primary Measures
