ARN Clinical Research

ARN Clinical Research is a U.S. rheumatology-focused clinical research organization launched by American Rheumatology Network in partnership with Trio Health. The business combines ARN's community rheumatology site network with Trio's real-world data and analytics capabilities to support clinical trial feasibility, patient identification and recruitment, study startup, data management, analytics, and commercial insight services. Its model is designed to accelerate manufacturer-sponsored drug development in rheumatology through integrated EMR-linked data, regulatory-grade data verification, and decentralized, hybrid, and pragmatic trial approaches. Rather than developing its own therapeutics, the company operates as a tech-enabled research services platform serving biopharma sponsors across the product lifecycle.
