MAINRITSAN study compared Rituximab and azathioprine as maintenance therapy for ANCA-associated vasculitides. In this study, Rituximab (5 infusions at D1, D15, M6, M12, M18) was superior to azathioprine (2 mg/kg/day) to prevent relapses of AAV 28 months after the inclusion (Guillevin et al. NEJM 2014). Nevertheless, in the follow-up study of MAINRITSAN, up to 30% of patients experienced a relapse 38 months after the last rituximab infusion (unpublished data). Right now, no randomized controlled study has been carried in order to evaluate the best duration of the maintenance treatment with rituximab.

The investigators objective is to evaluate the efficacy of a long term rituximab treatment to prevent relapses of ANCA-associated vasculitis in patients in remission after a first phase of rituximab maintenance treatment.

The investigators will conduct a randomized placebo-controlled trial of a long term rituximab maintenance treatment (46 months) against a conventional maintenance treatment (18 months).
