A Study Evaluating the Safety and Efficacy of Rituximab in Combination With Glucocorticoids in Participants With Wegener's Granulomatosis or Microscopic Polyangitis

This study is currently recruiting participants. (see Contacts and Locations)

This is a perspective, Phase IV, multi-center, single arm, open-label, interventional study in adult participants with Wegener's granulomatosis (granulomatosis with polyangiitis [GPA]) or microscopic polyangiitis. Participants will be treated with rituximab (Ristova) and glucocorticoids. Rituximab will be administered by intravenous (IV) infusion at a dose of 375 milligrams per meter square (mg/m^2) body surface area once weekly during Weeks 1 to 4. Participants will also receive one or three pulses of methylprednisolone (1000 milligram [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 participant is completely off the drug. The participants will be followed up for duration of 6 months from the date of starting rituximab therapy with three follow-up visits at Days 52, 112 and 172. All adverse events occurring during this period will be captured.

Arms Assigned Interventions
Experimental: Rituximab
Participants will receive IV infusion of rituximab once weekly from Week 1 to 4. Participants will also receive one pulse of methylprednisolone, followed by a tapering dose of oral prednisolone at the discretion of the investigator. Methylprednisolone may be repeated up to total of 3 pulses at the discretion of the investigator.
Drug: Methylprednisolone
Methyprednisolone will be administered 1 to 3 pulses at a dose of 1000 milligram (mg) IV at the discretion of the investigator.
Drug: Prednisone
Prednisone will be administered orally at tapered dose (start at 1 milligrams per kilogram per day [mg/kg/day]) at the discretion of investigator given daily until participants are off the drug.
Drug: Rituximab
Rituximab will be administered at 375 milligrams per meter square (mg/m^2) of body surface area given by IV infusion once weekly from Week 1 to 4.
Other Name: Ristova
