Levels of Gremlin — a protein that is overexpressed during kidney damage — in the urine may serve as a specific biomarker for ANCA-associated renal vasculitis, a study shows. The study, “Gremlin, A Potential Urinary Biomarker of Anca-Associated Crescentic Glomerulonephritis,” was published in the journal Scientific Reports.

The first patient has been dosed in InflaRx‘s ongoing European Phase 2 clinical trial testing the safety and efficacy of its IFX-1 investigational therapy for the treatment of ANCA-associated vasculitis (AAV), the company announced. IFX-1, the company’s lead drug candidate, is a first-in-class antibody designed…

With 250 rare diseases newly identified every year, scientists can barely keep up — even as the healthcare system fails millions of Americans whose rare diseases have already been diagnosed. That’s the warning from Christopher P. Austin, MD, director of the National Center for Advancing Translational Studies (NCATS) at…

ChemoCentryx remains on track to report topline results later this year from its ongoing Phase 3 clinical trial assessing the safety and efficacy of oral avacopan (CCX168) in patients with ANCA-associated vasculitis (AAV), the company announced. Avacopan is an investigational inhibitor of the complement C5a receptor,…

In patients with MPO-positive ANCA-associated vasculitis, the excess inflammation causes cerebral small vessel disease even before the disease is diagnosed, and the risk for cerebral disease may remain high even after immunosuppressive treatment, researchers say. The study with that finding, “Occurrence of cerebral small vessel disease…

A large proportion of patients with ANCA-associated vasculitis discontinue treatment while in remission, but they appear to have fewer relapses than those who never stopped treatment, a study has found. This suggests that, as long as patients and physicians remain in touch to identify relapses, patients in remission may…

Tumors in the thymus can lead to a malfunction of the immune system, and cause the appearance of ANCA-associated vasculitis, a case report suggests. However, the association is rare, and more cases are needed to establish a line of treatment. The study, “Microscopic polyangiitis associated with thymic tumor:…

Lupus nephritis patients positive for ANCA antibodies show mixed symptoms of systemic lupus erythematosus and ANCA-associated vasculitis, culminating in aggressive kidney disease that does not respond well to remission-inducing therapies, a case report suggests. The study, “Rapid progression to end‐stage renal disease in a young female with mixed…

With an estimated 1.37 billion inhabitants, India will likely surpass China in five years as the world’s most populous country. That also means it will have more rare-disease patients than any nation. It already has more than twice as many as the 28-member European Union. Harsha K. Rajasimha, a genomics…

A new test that recognizes anti-neutrophil cytoplasmic autoantibodies (ANCAs) targeting proteins other than myeloperoxidase (MPO) and proteinase-3 (PR-3) could improve the diagnosis and classification of ANCA-associated vasculitis, a study suggests. The study, “ANCA Beyond MPO & PR-3: the Clinical Utility of an Expanded ANCA Profile,” was recently presented at…
