It will also learn about the long-term safety of avacopan. The main questions it aims to answer are:\n\nIs avacopan in combination with short-term reduced-dose glucocorticoid and rituximab as effective as the combination of 20 week reduced-dose glucocorticoid and rituximab in the proportion of the patients achieving remission? Does avacopan lower the relapse rate compared to the 6 monthly rituximab maintenance therapy? What medical problems do participants have when taking long-term avacopan?\n\nParticipants will:\n\nBe treated with avacopan in combination with short-term (until 4 weeks) reduced-dose glucocorticoid and rituximab (at 0 week) or reduced-dose glucocorticoid (until 20 weeks) and rituximab (at 0, 26, 52 and 78 weeks).\n\nBe assessed at 0, 4, 8, 16, 26, 52, 78 and 104 weeks regarding disease status (remission/relapse), disease activity by Birmingham Vasculitis Activity Score ver3, disease damage by Vasculitis Damage Index and adverse events.\n\nThe primary endpoint is remission rates at 26 weeks.", "detailedDescription"=>"Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis is characterized by a small to medium-size vasculitis and the presence of ANCA. ANCA-associated vasculitis includes microscopic polyangiitis, granulomatosis with polyangiitis and eosinophilic granulomatosis with polyangiitis. ANCA-associated vasculitis can be a life-threatening disease and the mortality is 80% at 1 year in untreated patients. In 2010s, standard therapies for remission induction of ANCA-associated vasculitis were the combination of high-dose glucocorticoids and either cyclophosphamide or rituximab. Although those therapies have high remission rates of 80-90%, mortality at 5 years is still high at 10-20% mainly due to treatments-related adverse events.\n\nIn the LoVAS trial (2021, JAMA), the combination of reduced-dose glucocorticoid and rituximab showed non-inferiority to high-dose glucocorticoid and rituximab in remission rates at 6 months. In addition, adverse events were dramatically less in the reduced-dose group than in the high-dose group.\n\nIn the ADVOCATE trial (2021, NEJM), the combination of avacopan, newly developed complement C5a inhibitor, and rituximab or cyclophosphamide showed non-inferiority to high-dose glucocorticoid and rituximab or cyclophosphamide in remission rates at 6 months. The avacopan group was allowed to use glucocorticoid within 1 month from the trial entry, and over 80% of patients used glucocorticoid indeed. Regarding adverse events, they were less in the avacopan group than in the glucocorticoid group.\n\nAlthough both the reduced-dose glucocorticoid regimen in the LoVAS trial and the avacopan regimen in the ADVOCATE trial are effective and safe for patients with ANCA-associated vasculitis, there is no trial directly comparing both regimens at the moment. Thus, in this multicenter, open-label, randomized, non-ineriority, phase 4 trial, the investigators aim to investigate if the combination of avacoapn, short-term (4 weeks) reduced-dose glucocorticoid and rituximab is non-inferior to the combination of reduced-dose glucocorticoid (20 weeks) and rituximab. The investigators also compare safety profiles and disease relapse between the two groups. A total of 160 patients with new-onset ANCA-associated vasculitis (microscopic polyangiitis and granulomatosis with polyangiitis) will be recruited and randomized to the two treatments groups. The primary end point is remission rate at 26 weeks, and the patients will be followed until 104 weeks for assessing disease relapse and long-term safety."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria:\n\n1.
