Early-access Avacopan in Real-world ANCA-associated Vasculitis

The current study proposal aims to investigate the clinical practice variation of the initial use of avacopan for AAV patients in Europe. The study will describe patient characteristics and organ-specific clinical benefit of avacopan treatment in a unique, first-experience cohort of AAV patients. By studying the clinical practice variation of first-experience avacopan treatment, this study will be uniquely positioned to identify pivotal issues on the real-life implementation of avacopan treatment. These observational data can ultimately serve to address current knowledge gaps on avacopan treatment in AAV patients, improve the care and drug-access for AAV patients with avacopan treatment and generate new areas of research.
