Urgent: Rare Hereditary Angioedema Awareness Rises – New Treatments & Hope for 1,000 Koreans
SEOUL, SOUTH KOREA – November 1, 2024 – A spotlight is shining on Hereditary Angioedema (HAE), a rare and often misdiagnosed genetic condition, as medical experts urge increased awareness and faster diagnosis. Affecting an estimated 1,000 people in South Korea, HAE causes unpredictable and potentially life-threatening swelling attacks. This breaking news comes as advancements in treatment, including new pharmaceutical developments, offer renewed hope for patients and are attracting significant investor attention.

What is Hereditary Angioedema?
HAE isn’t your typical allergy. It’s a genetic disorder stemming from a deficiency or dysfunction of C1-esterase inhibitor, a crucial protein regulating inflammation. Unlike common allergies that cause hives and itching, HAE manifests as recurring episodes of swelling in various body parts – face, hands, feet, abdomen, even the airway. These attacks can last for days and, critically, can obstruct breathing if the throat swells. Professor Shim Ji-soo of Ewha Womans University Mokdong Hospital emphasizes that the average patient suffers for eight years before receiving an accurate diagnosis, enduring significant physical and emotional distress.
The Diagnostic Delay & Why It Matters
The core problem? Low awareness. Symptoms are often mistaken for allergies, digestive issues, or other conditions. Diagnosis involves blood tests to measure C1-INH levels and function, alongside a thorough evaluation of clinical symptoms and family history. Approximately 75% of cases have a family link, but a quarter arise from spontaneous genetic mutations, making detection even harder. The delay in diagnosis isn’t just about suffering; it’s about risk. Laryngeal edema – swelling of the airway – is a medical emergency requiring immediate attention.
New Treatments & Biotech Investment Opportunities
The landscape of HAE treatment is rapidly evolving, and with it, opportunities for biotech investment. Several companies are at the forefront of innovation:
- KalVista Pharmaceuticals (KALV, NASDAQ): Developing sevetralstat, a potential first-in-class oral treatment for acute HAE attacks. Recent FDA regulatory progress is a key indicator.
- Intellia Therapeutics (NTLA, NASDAQ): Pioneering a CRISPR-based gene editing therapy (NTLA-2002) that aims to prevent attacks by targeting the root genetic cause. Phase 2 trial results have been highly promising.
- BioCryst Pharmaceuticals (BCRX, NASDAQ): Marketing ORLADEYO, an oral treatment already approved in several countries, including Colombia, offering increased patient convenience.
- Pfizer (PFE, NYSE): Advancing Ducrictivant, a treatment showing positive clinical results in preventing and treating HAE attacks.
These advancements are driven by the unmet need for more convenient and effective treatments. Currently, many patients rely on emergency self-administered injections (icatibant acetate, covered in Korea since 2018), but an oral option would significantly improve quality of life. The global rare disease therapeutics market is booming, creating a favorable environment for these companies.
What Triggers an Attack?
While attacks can occur spontaneously, certain factors can increase the risk. These include stress, minor injuries, dental procedures, and even exposure to estrogen. Understanding these triggers can empower patients to proactively manage their condition.
Looking Ahead: Improving Access & Reducing Costs
Professor Shim Ji-soo stresses the importance of early diagnosis and treatment. She advocates for reduced diagnostic costs, expanded information resources, and improved access to emergency medications. These steps are crucial to enhancing the treatment experience for HAE patients in Korea and beyond. The increasing awareness, coupled with groundbreaking research and development, signals a brighter future for those living with this challenging rare disease.
