This is a perspective, phase IV, multi-center, single arm, open-label, interventional study in adult patients with Wegener's granulomatosis (granulomatosis with polyangiitis - GPA) or microscopic polyangiitis. Patients will be treated with Ristova and glucocorticoids. Ristova will be administered by intravenous (IV) infusion at a dose of 375 mg/m2 body surface area once weekly during Weeks 1 to 4. Patients will also receive one or three pulses of methylprednisolone (1000 mg each), followed by a tapering dose of oral prednisolone (start dose of 1 mg per kilogram per day). The dose of oral prednisone will be reduced as per evaluation by the investigator till the patient is completely off the drug. The patients will be followed up for duration of 6 months from the date of starting Ristova therapy with three follow-up visits at Days 52, 112 and 172. All adverse events occurring during this period will be captured.

Primary Outcome Measures:
  • Percentage of patients with Wegener's Granulomatosis (GPA) and microscopic polyangiitis achieving a Birmingham Vasculitis Activity Score for GPA (BVAS/WG) score of 0 and successful completion of the prednisone taper at 6 months [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of patients achieving BVAS/WG score of 0 during treatment with prednisone at a dose of less than 10 mg per day [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Percentage of patients with refractory antineutrophil cytoplasmic antibodies-associated vasculitis (AAV) achieving BVAS/WG score of 0 and successful completion of the prednisone taper [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Percentage of patients who achieve and maintain partial remission (defined as having a BVAS/WG of 1 or 2) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Number of severe flares [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Number of limited flares [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Incidence of adverse events [ Time Frame: 6 months ] [ Designated as safety issue: No ]
