Corrona was founded in 2001 by leading rheumatologists dedicated to advancing and improving the care of patients with autoimmune diseases.

Corrona's Mission is to advance medical research and improve patient care by providing unique, proprietary data on treatment efficacy and outcomes of patients with autoimmune diseases in a real-world setting.

About Corrona


Corrona is a real world evidence business providing registry data and consulting services to biopharmaceutical companies. Our clients face major challenges to demonstrate the health outcomes of their drugs. This may be achieved through legislative and regulatory-mandated pathways (e.g., post-approval surveillance requirements, REMS programs, pharmacovigilance plans), by analyzing comparative effectiveness data to generate potential new claims, or measuring health outcomes to justify the value of the drug to payers.

The Corrona model for data collection involves developing and sustaining a robust network of affiliate clinical sites, both academic and private, which contribute data from both physicians and patients. The sites are compensated for their data collection and submission efforts. All research programs are conducted under the oversight of a contracted Institutional Review Board or other local authority (e.g., an academic site). The data that are collected from the sites undergoes quality control for accuracy and completeness, and is stored in a secure data warehouse for access by Corrona biostatisticians and epidemiologists.

Corrona is an independent registry without any ownership links to the pharmaceutical industry.
