NCT05578417

Brief Summary

The main aim of this study is to describe the characteristics of participants, check for number of hereditary angioedema (HAE) cases, their treatment and outcomes. Another aim is to check how the healthcare facilities were utilized for treatment. Participants' data will be taken from their medical records (charts), which were already collected as a part of their routine care between January 1, 2012, and January 1, 2022.
