Comparison of a Strategy Based on Clinico-biological Monitoring Versus Pre-emptive Rituximab Treatment in Cases of ANCA Reappearance in Granulomatosis With Polyangiitis and Microscopic Polyangiitis.

The PREP-ANCA study seeks to establish a more personalized treatment strategy for ANCA-associated vasculitides by assessing the efficacy of pre-emptive rituximab administration upon ANCA repositivity in preventing relapses in granulomatosis with polyangiitis and microscopic polyangiitis.

Safe Effective Therapy With Low-Dose Glucocorticoid in ANCA-Associated Vasculitis (SAFE-LOW)

The purpose of this study is to determine the safety and efficacy of a therapeutic regimen consisting of 4 weeks of glucocorticoids given with a combination of the usual induction agents for ANCA-associated vasculitis. The trial will compare this regimen to the current standard of care treatment and glucocorticoid dosing for ANCA-associated vasculitis with severe kidney involvement. This trial will begin as a pilot to assess feasibility of recruitment and of adherence to the intervention.

Vasculitis Pregnancy Registry

The purpose of this study is to learn about the experience of women with vasculitis who become pregnant. In particular, the study will consist of several online surveys to assess 1. each woman's vasculitis severity and pregnancy-related experiences, and 2. pregnancy outcomes.

Clinical Transcriptomics in Systemic Vasculitis (CUTIS)

Multi-center observational study to evaluate the histopathology and transcriptome of cutaneous lesions in patients with several different types of vasculitis.

Special Drug Use-results Survey for Long-term Use（Avacopan）

The purpose of this survey is evaluating the safety and efficacy of long-term administration of avacopan for Japanese patients with microscopic polyangiitis or granulomatosis with polyangiitis under actual conditions of use.
