Hereditary Angioedema (HAE) Market Outlook

Hereditary Angioedema (HAE) Overview

Hereditary angioedema (HAE) is a rare and potentially life-threatening autosomal dominant disorder caused by the dysregulation of the contact system, leading to an overproduction of the peptide bradykinin, which induces recurrent episodes of non-pitting, non-itchy swelling. While you correctly noted the three traditional types—Type I (low C1-inhibitor levels), Type II (functional deficiency), and HAE with normal C1-INH—the 2026 clinical landscape now further classifies the third group by specific mutations in genes like Factor XII, plasminogen, or angiopoietin-1. The hallmark of the disease is its unpredictability, where swelling of the extremities, face, or airway can be triggered by stress or trauma, while gastrointestinal involvement often causes “pseudo-surgical” abdominal pain that historically led to unnecessary appendectomies before proper diagnosis. In 2026, the management paradigm has shifted from simply controlling symptoms to a “total control” strategy through long-term prophylaxis with monoclonal antibodies like lanadelumab or oral kallikrein inhibitors like berotralstat. Most significantly, the first CRISPR-based gene therapies, such as NTLA-2002, have entered late-stage clinical trials in 2026, aiming to provide a functional cure by permanently reducing kallikrein levels and effectively ending the cycle of attacks for many patients.
