Introduction
Churg-Strauss Syndrome (EGPA) is a rare autoimmune vasculitis characterized by asthma, chronic sinusitis, eosinophilia, and inflammation of blood vessels. The disease can affect multiple organ systems, including lungs, skin, nerves, and the cardiovascular system.

Advancements in biologic therapies, genetic testing, ANCA profiling, and eosinophil-targeted treatment are improving disease control and reducing long-term corticosteroid dependence. Increasing diagnosis rates and greater awareness of eosinophilic disorders are driving consistent market growth.

Market Story: What's Driving the EGPA Market?
The EGPA market is expanding due to several global healthcare trends:
• Rising prevalence of asthma and eosinophilic disorders, increasing screening for EGPA
• Strong demand for biologics, especially IL-5 inhibitors such as mepolizumab
• Improved diagnostic capabilities including ANCA testing, eosinophil profiling, CT imaging, and biopsy techniques
• Expansion of multidisciplinary care involving rheumatology, pulmonology, and immunology
• Increasing clinical focus on steroid-sparing treatment approaches
• Growth in rare disease research funding and patient registries
• Broader access to telemedicine for chronic autoimmune disease management
The shift toward precision medicine is enabling better symptom control and long-term remission in EGPA patients.
