In patients with AAV, the most important questions are how to achieve a long-term remission and prevent a relapse most effectively.\n\nThe pivotal RAVE trial showed that rituximab therapy was not inferior to daily cyclophosphamide treatment for induction of remission in AAV; and could be superior than cyclophoshamide in proteinase 3 (PR3)-ANCA patients. The MAINRITSAN trial, conducted by our group (Groupe Français d'Etude des Vascularites), has then demonstrated that more AAV patients had sustained remission with rituximab than with azathioprine.\n\nHowever, despite its ability to induce and maintain remission, rituximab is associated with the occurrence of relapse after discontinuation in up to 50% of patients at 5-years in PR3-ANCA patients. Data strongly suggest that achieving clinical and serological remission (i.e. a BVAS (Birmingham Vasculitis Activity Score) of 0 and a negativation of ANCA) and longer B-cell depletion could be major goals to achieve in PR3-ANCA granulomatosis with polyangiitis to decrease the risk of relapse.\n\nObinutuzumab is a humanized type 2 antibody targeted against CD20. In preclinical studies, obinutuzumab showed superior efficacy, as compared with rituximab. In clinical studies, obinutuzumab was shown to be superior to rituximab in patients with chronic lymphocytic leukemia and follicular lymphoma, and met its primary and secondary endpoints in lupus nephritis.\n\nThe OBI-WAN study aims to evaluate the efficacy and safety of obinutuzumab to induce clinical and serological remission in patients with relapsing PR3-ANCA granulomatosis with polyangiitis. We hypothesize that obinutuzumab would induce higher remission rates and subsequent longer B-cell depletion compared to what is described for rituximab."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patient aged of 18 years or older,\n* Patients with relapsing granulomatosis with polyangiitis positive for PR3-ANCA (at initial diagnosis or during follow-up), according to the ACR/EULAR 2022 classification criteria, and/or the 2012 revised Chapel Hill Consensus Conference definition.\n* Patients with an active disease defined as a Birmingham Vasculitis Activity Score (BVAS) ≥ 3,\n* Patients within the first 21 days following initiation/increase of glucocorticoids at a dose ≤1 mg/kg/day (pulses of methylprednisolone before oral glucocorticoid therapy are authorized)\n* Patient able to give written informed consent prior to participation in the study, - Affiliation with a mode of social security (profit or being entitled).\n\nExclusion Criteria\n\n* Patients with MPO-positive AAV, or other vasculitis, defined by the ACR criteria and/or the Chapel Hill Consensus Conference,\n* Patients with vasculitis in remission of the disease defined as a BVAS \\< 3,\n* Patients with a newly-diagnosis of GPA\n* Patients treated with rituximab within the last 6 months before inclusion\n* Patients treated with cyclophosphamide within the last 6 months before inclusion\n* Patients with severe cardiac failure defined as class IV in New York Heart Association\n* Subject known to be seropositive for human immunodeficiency virus (HIV), hepatitis B (included history of previous infection) or hepatitis C\n* Patients with active cancer or recent cancer (\\< 5 years), except basocellular carcinoma and prostatic cancer of low activity controlled by hormonal treatment,\n* Patients with hypersensitivity to a monoclonal antibody or biologic agent,\n* Patients with hypersensitivity to obinutuzumab or to its excipients\n* Contra-indications to auxiliary medicinal products (methylprednisolone, paracetamol, prednisone, dexchlorpheniramine)\n* Patients with other uncontrolled diseases, including drug or alcohol abuse, active infections or antecedents of chronic or recurrent infections, severe psychiatric diseases, that could interfere with participation in the trial according to the protocol,\n* Patients suspected not to be observant to the proposed treatments,\n* Pregnant women and lactation.
