Filter by:The purpose of this study is to investigate, after achievement of remission, the efficacy of rituximab compared with azathioprine maintenance therapy on duration of remission, in patients with relapsing or newly-diagnosed Eosinophilic granulomatosis with polyangiitis EPGA receiving standard of care therapy including glucocorticoid therapy reduction/withdrawal.
EGPA (Eosinophilic Granulomatosis with Polyangiitis, previously Churg-Strauss syndrome) is a rare vasculitis, characterised by asthma, rhinosinusitis and eosinophilia. There has previously been confusion around diagnostic criteria, with multiple sets of classification criteria being used inappropriately for diagnosis. The ERS formed a taskforce to produce specific diagnostic criteria, and these divided the Churg-Strauss Syndrome cohort into two groups - vasculitic EGPA and tissular Hypereosinophilic Asthma with Systemic Manifestations (HASM). It is not known if the groups separated by the diagnostic criteria are also separated in clinical symptomatology, or if their disease course varies, and this could have significant impact on management and further research.
Multi-center observational study to evaluate the histopathology and transcriptome of cutaneous lesions in patients with several different types of vasculitis.
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.
Reslizumab is a type of medicine called a monoclonal antibody that is made in the research clinic; it works by blocking a specific protein in the body called interleukin-5. The study medicine, reslizumab, is not yet approved for doctors to treat patients with EGPA. It is considered an experimental drug in this study.
Current diagnostic tools used in interstitial lung disease (ILD) do not meet the challenges set by the complex pathophysiology of this heterogenous group. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of patients with various ILDs.
Phase III, comparative, multicenter, randomized, controlled, double-blind and superiority research, comparing rituximab-based regimen with conventional therapeutic strategy for the induction of remission in patients with eosinophilic granulomatosis with polyangiitis (EGPA). Patients with newly diagnosed or relapsing EGPA will be randomized in a 1:1 ratio to receive: - Experimental therapeutic strategy based on the use of rituximab (experimental group) - Conventional therapeutic strategy based on Five-Factor Score (FFS)-assessed disease severity (comparative group)
This is a phase IV, single-center, randomized, placebo-controlled pilot study that will evaluate the efficacy of rituximab at inducing otolaryngologic remission in GPA patients with active otolaryngologic disease.
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.
The aim of this project is to develop a disease specific patient reported outcome measure (PROM) for patients with AAV (the AAV-PRO). Investigators are developing and validating a questionnaire to assess quality of life in patients with ANCA-associated vasculitis (AAV). Patients with AAV have inflammation in the small blood vessels leading to involvement of a range of organs and can suffer from ongoing disease activity or treatment side effects. Quality of life can be measured by patient reported outcome measures (PROMs).
