Biocollection of Patients With ANCA Associated Vasculitis (ANCA)

June 24, 2026 updated by: University Hospital, Brest

Biocollection of Patients With ANCA Associated Vasculitis Diagnosed Within the CERAINO Autoimmune Disease Reference Center, Part of the Global BRAISE Project (B-dependent Rare AutoImmune DiseaSES

As rare disease, vasculitis affects a small number of patients, the cohorts available in the literature are few and the pathophysiological mechanisms remain to be elucidated. The collection of standardized data within a patientheque as part of a multi-year follow-up will facilitate the study of the characteristics of these diseases. This may, in particular, address the main objective of identifying predictors of relapse, as well as secondary objectives for predictive factors of mortality, infectious, cardiovascular or neoplastic complications that affect the prognosis of vasculitis in order to establish a more appropriate management of the patients concerned.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Detailed Description

Vasculitis associated with anti-neutrophil cytoplasm antibodies (ANCA) is a group of rare and severe autoimmune diseases, encompassing several entities: granulomatosis with polyangiitis (GPA), microscopic polyangiitis (PMA), and eosinophilic granulomatosis with polyangiitis (GEPA). When untreated, these diseases are fatal in a matter of months. Currently, thanks to the use of corticosteroids and immunosuppressants, this high mortality has greatly decreased and these are now chronic diseases. On the other hand, these patients are at high risk of morbidity, linked to both relapses (occurring in at least 50% of patients) and side effects of treatments. It is therefore essential to be able to define which patients are at risk of relapse and justify long-term immunosuppressive treatment to avoid recurrence of the disease, and conversely which patients have a low risk of relapse and in whom immunosuppressive treatments can be discontinued to limit the risk of side effects. However, so far no predictor or biomarker can accurately assess this risk of relapse.

Enrollment (Estimated)

Enrollment

100

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: Five years after diagnosis

This is for recording organ damage that has occurred in patients since the onset of vasculitis, and over 3 months. Record features of active disease using the Birmingham Vasculitis Activity Score (BVAS).

A new patient should usually have a VDI score of zero, unless:

  1. they have had vasculitis for more than three months of onset of disease. and
  2. the damage has developed or become worse since the onset of vasculitis Questionnaire listing 64 symptoms divided into eleven organ/systems classes. For each item, the assessor evaluates if it is present over 3 months and attribuable to the active vasculitis or not. A higher score means a worse outcome.
