Trial summary

Hereditary angioedema (HAE) is a rare condition. It causes sudden swelling under the skin and inside the body, like in the belly, throat, or genitals. This swelling happens because of a temporary leak in blood vessels. Read more about this study

About this study

Official title: Retrospective and Prospective Real-World Evidence (RWE) Study Investigating Diagnosis and Therapeutic Management of Patients With HAE Type I or II in the Current Medical Practice in Egypt: the EXPLORHAE Study (EXPLORing Prospective and Retrospective Health Assessments of HAE in Egypt)

Hereditary angioedema (HAE) is a rare condition. It causes sudden swelling under the skin and inside the body, like in the belly, throat, or genitals. This swelling happens because of a temporary leak in blood vessels. HAE is classified based on the amount of a protein in the blood called C1 inhibitor (C1-INH): HAE with normal C1-INH levels and HAE with limited or insufficient C1-INH levels (C1-INH deficiency); HAE with C1-INH deficiency can be divided into Type1, with low levels of C1-INH, and Type 2, in which the protein is there, but does not work properly. This study will look at people with HAE Type1 or Type2.

The main aim of this study is to describe the diagnosis and management of people with HAE Type1 or HAE Type2 in Egypt. Other aims are to learn more about people with HAE Type1 or Type2, including, but not limited to, other conditions they may have, family history, impact of HAE on daily life, if treatment is stopped and the reasons.

During the study, information from already existing data in a participant's medical record will be reviewed and new data will be collected during routine visits of a participant to the study clinic.
