Is this trial a fit for you?

Likely a good fit

People aged 12 years or older with a confirmed diagnosis of hereditary angioedema who are newly starting garadacimab as prescribed by their physician, can provide consent (or have guardian consent), and can use a smartphone or computer for data entry are ideal candidates.

Probably not a fit

Patients with other forms of angioedema (such as acquired, idiopathic, or histaminergic) or those not starting garadacimab are not eligible and are unlikely to receive benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multinational, multicenter prospective observational cohort following patients newly initiating garadacimab in routine clinical practice. Each participant will be followed for 48 months after their first dose, with data collected from an electronic HAE eDiary, medical records, and routine clinic visits. The study extracts 12 months of retrospective healthcare resource and safety data from records and 3 months of retrospective attack data from the eDiary. No treatments are assigned by the study; garadacimab use is determined by the treating physician per local labeling.

Why it matters

Potential benefit: If successful, this could show that garadacimab reduces attack frequency and improves quality of life for people with HAE in everyday clinical practice.

How similar studies have gone: Previous clinical trials of garadacimab have reported promising reductions in HAE attack rates, but long-term real-world safety and effectiveness data are still limited.
