Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are patients with a confirmed diagnosis of granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) who are starting treatment with avacopan.

Probably not a fit

Patients without active AAV disease or those under 16 years old may not benefit from this study.

What this trial studies

This observational study aims to analyze the variation in clinical practice regarding the early use of avacopan in patients with ANCA-associated vasculitis (AAV) across Europe. It will describe patient characteristics, treatment indications, and clinical outcomes associated with avacopan treatment. By focusing on real-world data, the study seeks to identify key issues in the implementation of avacopan, ultimately addressing knowledge gaps and improving patient care. The cohort will consist of AAV patients who have initiated treatment with avacopan, allowing for a comprehensive understanding of its effects and associated treatment strategies.

Why it matters

Potential benefit: If successful, this study could enhance the understanding and accessibility of avacopan treatment for patients with ANCA-associated vasculitis.

How similar studies have gone: While this study focuses on real-world data, similar observational studies have shown promise in understanding treatment variations and outcomes in other conditions.
