How do people living with HAE prepare for and treat attacks?

THE HAE ATTACK JOURNEY SURVEYED PEOPLE LIVING WITH HAE WITH THE GOAL OF UNDERSTANDING:

There are times when people living with HAE delay on-demand treatment or decide not to treat an HAE attack. The HAE Attack Journey Survey has revealed that many people living with HAE find it difficult to carry their on-demand treatment and struggle with the anxiety of whether to treat when they recognize an attack. Lack of privacy required to administer medication, preferring to treat at home, and fear of injection or pain of medication are 3 of the most common reasons for delaying treatment.

The HAE Attack Journey survey included 107 people living with HAE

The HAE Attack Journey Survey was conducted by KalVista Pharmaceuticals in partnership with the HAE community to better understand how people living with HAE plan for an attack, make decisions about on-demand treatment, and how attacks impact their quality of life. This survey was based on the findings of an earlier pilot survey (N=32), which revealed that the majority of people living with HAE continue to experience a prolonged attack journey, despite advances in treatment.

The survey was conducted online from April to October 2022 and asked 107 members of the Hereditary Angioedema Association questions about HAE attacks and their current on-demand treatment experience.

THERE WERE 54 PEOPLE ON PROPHYLAXIS AND 53 TAKING ON-DEMAND ONLY

*For Firazyr, 44 people were on prophylaxis and on-demand, and 40 were taking on-demand only; for Ruconest, 3 people were on prophylaxis and on-demand, and 10 were taking on-demand only; for Berinert, 6 people were on prophylaxis and on-demand, and 3 were taking on-demand only; for Kalbitor, 1 person was on prophylaxis and on-demand, and 0 were taking on-demand only.

The HAE Attack Journey Survey showed that people living with HAE:

  • 1
    Continue to have attacks even
    if they’re taking prophylaxis
  • 2
    Go through a complex on-demand,
    decision-making process that
    results in delayed treatment
  • 3
    Have prolonged attacks and longer
    recovery, resulting in significant
    physical and psychological burden
