Hereditary Angioedema
Also known as HAE, C1 inhibitor deficiency, HAE-C1-INH, bradykinin-mediated angioedema
Hereditary angioedema causes recurrent episodes of swelling in the skin, abdomen, and airway. Types 1 and 2 are caused by SERPING1 mutations leading to C1-inhibitor deficiency.

About Hereditary Angioedema
Hereditary angioedema causes recurrent episodes of swelling in the skin, abdomen, and airway. Types 1 and 2 are caused by SERPING1 mutations leading to C1-inhibitor deficiency. This allows unchecked bradykinin production, causing plasma leakage and swelling. Laryngeal attacks can be life-threatening. Multiple approved therapies exist including C1-INH concentrate, icatibant, lanadelumab, and berotralstat. Trial activity is high for new long-acting and gene-based approaches.

Before you apply
Things trial teams commonly ask about for Hereditary Angioedema. Not eligibility rules; those are set by each study.
- HAE type (1, 2, or FXII) must be confirmed with C1-INH level, C1-INH function, and C4 tests
- Attack frequency (at least 3 attacks in 3 months is a common threshold) determines prophylaxis trial eligibility
- Current prophylactic therapy (lanadelumab, berotralstat) history affects enrollment in comparison trials
