Anti-neutrophil cytoplasmic antibody-associated vasculitis

This study looked at 159 people with granulomatosis with polyangiitis (GPA), a rare disease that causes inflammation of blood vessels. Participants were randomly assigned to either stay on a low 5 mg daily dose of prednisone or slowly stop it over six months. The goal was to see …

This study tested whether the drug rituximab, given with steroids, works better than steroids alone for people with a rare disease called microscopic polyangiitis that inflames small blood vessels. Only 8 patients took part, and the goal was to see if the combination could preven…

This early study looked at a new drug, MT-2990, in 5 people with ANCA-associated vasculitis, a rare disease where the immune system attacks blood vessels. The goal was to see if the drug is safe and how it affects disease activity. Researchers measured changes in symptoms, imagin…

This study looked at 201 Canadian patients with ANCA-associated vasculitis to see if cheaper biosimilar versions of rituximab work as well as the original drug. Researchers compared disease control, side effects, and how long it took to get insurance approval for treatment. The g…

This study tested whether rosuvastatin, a common cholesterol-lowering drug, could reduce early signs of artery hardening in 121 people with ANCA-associated vasculitis. Participants were in remission and received either rosuvastatin or a placebo for up to 2 years. The goal was to …

This study tested whether giving a stronger pneumococcal vaccine schedule (either two doses close together or a single larger dose) followed by a standard booster could improve immune protection in 96 adults with ANCA-associated vasculitis who are also receiving rituximab therapy…

This study tested whether rituximab, a targeted antibody therapy, is better than azathioprine, a standard immune-suppressing drug, at preventing relapses in people with ANCA-associated vasculitis. 117 patients who had achieved remission were randomly assigned to receive either ri…

This study looked at whether giving rituximab for 46 months instead of the usual 18 months can better prevent relapses of ANCA-associated vasculitis, a rare autoimmune disease that causes blood vessel inflammation. 97 patients who were already in remission after initial rituximab…

This small pilot study looked at whether the drug pirfenidone is safe and effective for people with a specific type of lung scarring (pulmonary fibrosis) linked to MPO antibodies or vasculitis. Seven adults took the drug for a year, and researchers measured changes in lung functi…

This study tested two ways of giving rituximab to people with ANCA-associated vasculitis, a rare disease where the immune system attacks blood vessels. All 166 participants were in remission and received rituximab either on a fixed schedule or only when certain blood markers (ANC…

This study followed 293 people with autoimmune diseases and healthy volunteers to see how COVID-19 infection or vaccination affects their immune system, inflammation, and blood vessels. Participants were grouped based on their COVID-19 history and had up to 5 visits over 12-18 mo…

This study looks at whether a protein in the blood, called soluble CD95 ligand, plays a role in ANCA-associated vasculitis, a rare group of diseases that cause inflammation of blood vessels. Researchers will collect blood and urine samples from 48 adults with the condition and tr…

This study looked at how certain immune cells, called neutrophils, behave in people with granulomatosis with polyangiitis (GPA), a rare blood vessel inflammation disease. Researchers collected blood samples from 93 participants, including patients with GPA and other related condi…
