Role of effective prophylaxis

Role of effective prophylaxis

Ineffective prophylaxis may not provide sufficient levels of rFVIII to assure protection from bleeds and completely prevent joint damage1


  • The historical aim of standard half-life rFVIII prophylaxis was to achieve trough levels of 1%, which may not be enough to completely prevent joint damage in all patients2
  • Lack of compliance to prophylaxis could lead to sub-optimal protection, resulting in increased bleeding, including joint bleeds3,4
  • Joint arthropathy, during prophylaxis with sub-optimal protection, may start sub-clinically and progress slowly, making early diagnosis and timely treatment difficult5

Joint arthropathy in primary prophylaxis develops subtly over many years, the ankle joints being the first and most severely affected5

  • The key to successful long-term outcomes, and for preventing long-term joint damage, is effective prophylaxis, that prevents bleeding into the joints,and quick and effective treatment of joint bleeds when they occur6

Effective adherent prophylaxis supports long-term joint health, which may help PwH to live a liberated life5,7
