Microscopic polyangiitis (MPA) patients with high blood levels of the inflammatory protein interferon gamma (IFN-gamma) at the onset of their disease are significantly more likely to have relapses despite treatment, a small study in Japan shows. The findings suggest IFN-gamma may serve as a biomarker to predict relapses in MPA,…

Fasenra (benralizumab) and Nucala (mepolizumab) appear to be equally safe and effective in helping adults with eosinophilic granulomatosis with polyangiitis (EGPA) achieve disease remission, according to a real-world study in Europe that directly compared the two approved therapies. Still, at one year, AstraZeneca’s Fasenra was associated with…

Adding Tavneos (avacopan) to standard treatment for the two main types of ANCA-associated vasculitis (AAV) results in fewer adverse events — including a lesser number of serious side effects and infections — in adults with granulomatosis with polyangiitis, or GPA, and microscopic polyangiitis, known as MPA. That’s according…

Elevated levels in the blood of ferritin, a protein that binds to iron and stores it for use by the body, are linked to more severe damage in people with active ANCA-associated vasculitis (AAV), and to a poorer outlook for the kidneys, according to a new study from China.

Testing for the presence of specific self-reactive antibodies linked to ANCA-associated vasculitis (AAV) may help doctors more easily tell microscopic polyangiitis (MPA) from granulomatosis with polyangiitis (GPA), the two most common types of AAV, a study showed. Classifying patients as MPA or GPA based on the different types…

Long-term treatment with Nucala (mepolizumab) — approved for use in EGPA, or eosinophilic granulomatosis with polyangiitis, the rarest type of ANCA-associated vasculitis — appears to be well tolerated by most patients, and was seen to reduce or even eliminate corticosteroid use. That’s according to new data from an…

A Phase 1 clinical trial assessing SC291, an experimental CAR T-cell therapy that Sana Biotechnology is developing for ANCA-associated vasculitis (AAV) and other autoimmune diseases, is recruiting patients at a number of sites across the U.S. Called GLEAM (NCT06294236), the study started enrolling up to…

A graphic prediction tool may accurately estimate the chance of survival over two years in people ANCA-associated vasculitis (AAV), according to a study at a single Chinese hospital. The tool, a nomogram based on 16 predictive factors, was able to differentiate patients who survived from those who didn’t with…

Physicians typically do not overestimate the overall health of people with ANCA-associated vasculitis (AAV), a study of global assessments made by patients and their doctors in Australia reports. In cases where ratings between these two groups markedly differed, doctors tended to assign a lower score than did the people…

Adicet Bio has pushed to the second half of 2025 the expected timing for enrolling patients with ANCA-associated vasculitis (AAV) in an ongoing Phase 1 clinical trial testing ADI-001, an experimental CAR T-cell therapy for a number of autoimmune diseases. The company had said it expected enrollment…
