Hereditary Angioedema (HAE) Market Outlook

Thelansis’s “Hereditary Angioedema (HAE) Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2026 To 2036” covers disease overview, epidemiology, drug utilization, prescription share analysis, competitive landscape, clinical practice, regulatory landscape, patient share, market uptake, market forecast, and key market insights under the potential Hereditary Angioedema treatment modalities options for eight major markets (USA, Germany, France, Italy, Spain, UK, Japan, and China).

Hereditary Angioedema (HAE) Overview

Hereditary angioedema (HAE) is a rare autosomal dominant disorder characterized by recurrent, self-limiting episodes of non-pruritic subcutaneous and submucosal edema affecting the skin, GI tract, and upper airway. Driven by SERPING1 mutations, Type I causes deficient C1-inhibitor (C1-INH) levels while Type II results in dysfunctional C1-INH protein, both leading to unregulated bradykinin production and vascular permeability. Attacks present as localized swelling or severe abdominal pain, with laryngeal edema posing a fatal asphyxiation risk. Diagnosis relies on low C4 levels and specific quantitative or functional C1-INH assays. While acute care historically required injectable C1-INH concentrates or the subcutaneous B2 receptor antagonist icatibant, the acute paradigm has been transformed by Ekterly (sebetralstat), the first oral plasma kallikrein inhibitor approved for on-demand use. Long-term prophylaxis has similarly advanced past traditional options like berotralstat or lanadelumab. Prophylactic protocols now feature Andembry (garadacimab), a monthly monoclonal antibody targeting Factor XIIa at the top of the cascade, alongside Dawnzera (donidalorsen), a first-in-class RNA-targeted antisense oligonucleotide that dampens prekallikrein production. Routine clinical tracking and prompt patient access to these targeted mechanisms are required to minimize attack frequency and guarantee safety.
