Eosinophilic Inflammation Biologic Therapies Market Size and Forecast

The global eosinophilic inflammation biologic therapies market was valued at USD 18.9 billion in 2025 and is projected to reach USD 37.4 billion by 2032, growing at a CAGR of 10.2%. Growth is driven by increasing prevalence of eosinophilic disorders, expanding biologics pipelines, improved disease phenotyping, and strong payer support for targeted therapies in severe inflammatory conditions.

Market Overview

Eosinophilic inflammation biologic therapies are advanced immunomodulatory treatments designed to selectively suppress eosinophil-mediated immune responses that drive chronic allergic and inflammatory diseases. These therapies target key cytokines and receptors involved in eosinophil survival, activation, and tissue infiltration, enabling disease control with fewer systemic side effects compared to traditional treatments. The market is characterized by strong clinical evidence, high unmet need in refractory patient populations, and robust long-term treatment demand. Biologics have transformed disease management paradigms by enabling phenotype-based therapy selection. As diagnostic capabilities improve, the addressable population continues to expand. The market remains innovation-driven, with lifecycle extensions and new mechanism exploration shaping competition.
