Summary

The aim of this study is to assess the efficacy of a rituximab regimen based on rate of ANCA and CD19 lymphocytes for maintenance treatment in systemic ANCA-associated vasculitis: prospective, multicenter, controlled, randomized comparative study of two rituximab regimens: one based on ANCA and CD19 lymphocytes versus systematic infusions.

Conditions

  • Granulomatosis With Polyangiitis
  • Microscopic Polyangiitis
  • Renal Limited Forms

Interventions

DRUG

Rituximab (Arm B)

Rituximab infusion will be performed at D1 then ANCA status and CD19+ lymphocyte count will be monitored every 3 months, and patients will receive new 500 mg rituximab infusions either if CD19 are \> to 0/mm3, or if ANCA are positive again or if ANCA titer significantly raises. All patients received corticosteroids, starting from induction with prednisone (or equivalent) at a dose of 1 mg/kg/day with gradual tapering according to a regimen adjusted to body weight over a mean of 18 months since diagnosis.

DRUG

Rituximab (Arm A)

Rituximab infusion will be performed at D1, D15, M6, M12 and M18(i.e. a total of 5 infusions), at the dose of 500 mg at a fixed dosage.All patients received corticosteroids, starting from induction with prednisone (or equivalent) at a dose of 1 mg/kg/day with gradual tapering according to a regimen adjusted to body weight over a mean of 18 months since diagnosis.
