Brief Summary

Current standard therapy for patients with haemophilia (PwH) in the prevention of bleeding episodes is a prophylactic intravenous treatment with recombinant coagulation factor (F) VIII (Haemophilia A) or rather FIX (Haemophilia B) two to three times weekly. With the development of recombinant factor VIII Fc fusion protein (rFVIIIFc) the conventional routine prophylaxis regime is complemented by an extended half-life (EHL) factor replacement prophylaxis with the potential of improved bleed prevention and reduced injection frequency at similar factor consumption. Aim of this longitudinal multicentre study is to evaluate the influence of an EHL factor replacement regime with rFVIIIFc on haemophilic specific parameters (annual bleeding rate, bleeding localisation), joint status, pain, functional parameters, treatment adherence and health-related quality of life in PwH A.

Outcome Measures

Primary Outcomes (3)

  • total annual bleeding rate

    number of total bleedings

    one year

  • orthopaedic joint status (Haemophilia health joint score)

    The clinical joint status will be examined in all patients with haemophilia by the World Federation Joint Examination Score and Haemophilia Joint Health Score. Higher score points imply an increased deficit in the functional and structural joint status as a sign of more pronounced haemophilic arthropathy, with a maximum possible value of 124 (no deficits = 0).

    one year

  • pressure pain thresholds

    physiological Parameter in Newton

    one year

Secondary Outcomes (4)

  • spontaneous joint ABR

    one year

  • subjective quality of life (SF-36)

    two years

  • subjective physical performance (HEP-Test-Q)

    two years

  • self-perceived functional abilities (Haemophilia Activities List)

    two years
