Argenx has decided not to go ahead with its development plans for efgartigimod as a potential treatment for ANCA-associated vasculitis (AAV) after the therapy failed to show beneficial effects in late-stage clinical trials of two other autoimmune diseases. Efgartigimod is approved in the U.S. in two formulations for…

Amgen is planning to launch a Phase 3 clinical trial testing Tavneos (avacopan) — its approved therapy for adults with ANCA-associated vasculitis (AAV) — in combination with a standard regimen of rituximab or cyclophosphamide in children and adolescents with active AAV. That’s according to a company press release…

Sinonasal symptoms, as assessed with 22-item Sinonasal Outcome Test (SNOT-22), a patient-reported questionnaire, are more severe when ANCA-associated vasculitis (AAV) is active than during remission, a study shows. Sinonasal symptoms are those that affect the nose and the sinuses, that is, the air-filled cavities around the eyes and nose.

Patrys’ PAT-DX1 and PAT-DX3, two DNA-targeting antibodies known as deoxymabs, can suppress production of the antimicrobial webs implicated in ANCA-associated vasculitis (AAV) without weakening other immune responses, according to preclinical work. These webs, called neutrophil extracellular traps (NETs), are made up of a scaffold of DNA and enzymes…

Having microscopic polyangiitis (MPA) or granulomatosis with polyangiitis (GPA) — the two most common types of ANCA-associated vasculitis (AAV) — better determines patients’ clinical features and outcomes than the type of AAV-driving, self-reactive antibodies they have. That’s according to a study in Spain that showed that GPA was an…

ANCA-associated vasculitis (AAV) patients receiving a cumulative dose of at least 935 mg of glucocorticoids over six months are more likely to see clinically meaningful side effects, according to a study using calculations based on the Glucocorticoid Toxicity Index (GTI). The findings suggest the GTI, which considers the frequency…

Recruitment is continuing in three countries for a Phase 1b/2a clinical trial testing Alpine Immune Sciences’ povetacicept in adults with autoimmune conditions affecting the kidneys, including ANCA-associated vasculitis (AAV). Called RUBY-3 (NCT05732402), the early study is designed to enroll an estimated 56 patients, ages 18 and older,…

The Renal Risk Score may be a better histopathologic classification model than Berden for predicting long-term loss of kidney function in people with ANCA-related vasculitis (AAV) who have glomerulonephritis, an inflammation of the kidneys’ filtering units, a study finds. Incorporating the renal risk score into clinical decision-making could help…

The Kidney Disease: Improving Global Outcomes (KDIGO) work group has released an updated practice guideline based on developments in how best to manage ANCA-associated vasculitis (AAV) associated with inflammation or damage to the kidneys. The guideline now offers advice on the use of lower doses of…

Tavneos (avacopan) improved kidney function and reduced the need for the glucocorticoid prednisone in four older patients who had signs of kidney failure due to ANCA-associated vasculitis (AAV), researchers in Canada report. While Tavneos may help patients enter into remission without the harmful side effects of glucocorticoids, “more…
