简要总结

To evaluate the superiority of pre-emptive treatment with rituximab compared to clinic-biological monitoring every 3 months in the event of ANCA reactivation in patients with GPA and MPA who were previously treated with rituximab for 18 months and are in complete remission. The primary outcome is the maintenance of remission, defined by a Birmingham Vasculitis Activity Score (BVAS) of 0.
