Official title
Longitudinal Protocol for Eosinophilic Granulomatosis With Polyangiitis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare immune system disorder that causes asthma, an excessive number of eosinophils (a type of white blood cell) in the blood, and the inflammation of blood vessels, or vasculitis. In order to properly treat EGPA, it is critical that the level of disease activity can be determined over the course of the disease. The purpose of this study is to determine new biological markers, or biomarkers, that may be used to assess the severity of this disease in people with EGPA.
