Trial of Efficacy and Safety of NS-229 Versus Placebo in Patients With Eosinophilic Granulomatosis With Polyangiitis

This study will enroll male and female subjects who are 18 years of age or older with Eosinophilic Granulomatosis With Polyangiitis.

Longitudinal Study for Eosinophilic Granulomatosis With Polyangiitis

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.

VCRC Tissue Repository

The purpose of this study is to collect existing tissue specimens from subjects enrolled in Vasculitis Clinical Research Consortium (VCRC) studies. Analysis of these tissue specimens and linked clinical data collected through VCRC studies may lead to the identification and development of a series of translational research projects. Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular diseases.

A Study to Evaluate the Efficacy and Safety of SHR-1703 in Subjects With Eosinophilic Granulomatosis With Polyangiitis （EGPA）

This study is a phase 2/3 clinical trial to evaluate the efficacy and safety of SHR-1703 in patients with EGPA.

Efficacy and Safety of Depemokimab Compared With Mepolizumab in Adults With Relapsing or Refractory Eosinophilic Granulomatosis With Polyangiitis (EGPA)

This study aims to investigate the efficacy and safety of depemokimab compared with mepolizumab in adults with relapsing or refractory EGPA receiving SoC therapy.

Study of Mepolizumab-based Regimen Compared to Conventional Therapeutic Strategy in Patients With Eosinophilic Granulomatosis With Polyangiitis (E-merge)

The purpose of this study is to compare mepolizumab-based regimen to conventional therapeutic strategy for remission induction in patients with Eosinophilic Granulomatosis with Polyangiitis.
