Hereditary Angioedema Market Poised for Strong Growth, Valued at ~USD 3 Billion in 2023 and Set to Expand Through 2034: DelveInsight

Key companies active in the Hereditary Angioedema space include Ionis Pharmaceuticals, Astria Therapeutics, KalVista Pharmaceuticals, Intellia Therapeutics, BioMarin Pharmaceutical, CSL Behring, Pharvaris Netherlands B.V., Takeda, Shire, and several other industry participants.
The Hereditary Angioedema (HAE) market was valued at nearly USD 3 billion in 2023 and is poised for robust expansion, largely fueled by the approval and uptake of novel therapeutic options. HAE is a rare inherited disorder marked by repeated, unpredictable episodes of severe swelling affecting the face, extremities, gastrointestinal system, and upper airway. Available treatment options include C1-esterase inhibitor (C1-INH) replacement therapies such as BERINERT and RUCONEST, kallikrein inhibitors like ecallantide, and bradykinin B2 receptor antagonists including FIRAZYR. Preventive therapies such as CINRYZE, HAEGARDA, and lanadelumab are also widely used. The United States dominates the global HAE market, accounting for close to 90% of total revenue, while women represent approximately 65% of the diagnosed patient population.

The HAE development pipeline remains highly active, with several promising candidates including navenibart (STAR-0215), donidalorsen, NTLA-2002, and sebetralstat. Significant developments in 2024 included the FDA's acceptance of Ionis Pharmaceuticals' NDA for donidalorsen, KalVista Pharmaceuticals' NDA filing for sebetralstat, and Astria Therapeutics' strategic collaboration with Ypsomed for STAR-0215. Notably, positive Phase III OASIS-HAE trial outcomes for donidalorsen demonstrated more than a 90% reduction in attack frequency, highlighting strong potential for future market growth.

DelveInsight's publication, "Hereditary Angioedema Market Insights, Epidemiology, and Market Forecast - 2034," offers an in-depth evaluation of the HAE landscape. The report analyzes historical and forecasted epidemiology alongside market trends across the United States, EU4 (Germany, Spain, Italy, and France), the United Kingdom, and Japan.

Hereditary Angioedema Overview

Hereditary Angioedema (HAE) is an uncommon inherited condition characterized by recurrent, severe swelling episodes involving the face, limbs, gastrointestinal tract, and airway, which may become life-threatening without timely intervention. The disease is caused by a deficiency or functional impairment of C1-esterase inhibitor, resulting in excessive bradykinin production and increased vascular permeability. HAE is categorized into Type I, Type II, and normal C1-INH variants. Women constitute the majority of affected individuals, and attacks may be triggered by stress, trauma, or hormonal fluctuations. Treatment strategies include on-demand agents such as C1-INH concentrates, kallikrein inhibitors, and bradykinin receptor antagonists, along with preventive therapies like lanadelumab and HAEGARDA. Emerging modalities, including RNA-based treatments, monoclonal antibodies, and gene-editing approaches, aim to deliver more durable and convenient disease control. Despite progress, challenges remain in achieving global access and long-term disease modification.

Hereditary Angioedema Drug Uptake and Pipeline Highlights

Donidalorsen (Ionis Pharmaceuticals):

Donidalorsen (IONIS-PKK-LRx) is an investigational ligand-conjugated antisense therapy developed by Ionis Pharmaceuticals to suppress plasma prekallikrein production, a key driver of HAE attacks. By reducing PKK levels, the therapy aims to effectively prevent acute episodes. In the Phase III OASIS-HAE study, subcutaneous administration every four weeks reduced monthly attack rates by 81% compared with placebo, while eight-week dosing achieved a 55% reduction.

Navenibart (Astria Therapeutics):

Navenibart (STAR-0215) is a long-acting monoclonal antibody targeting plasma kallikrein, designed for sustained HAE prevention with dosing every three or six months. Data from the ALPHA-STAR Phase Ib/II trial demonstrated a 90-96% reduction in attack frequency, along with favorable safety and tolerability. Based on these outcomes, Astria plans to initiate Phase III trials in early 2025, with top-line results anticipated by late 2026.
