GPA and MPA Treatment

Treatment options for GPA and MPA

There are a few different treatment options available for your active disease. Your doctor will decide which treatment is right for you based on your medical history and the severity of your disease. The goal of treatment is to reduce the inflammation and control your symptoms. 

You and your doctor may discuss different types of treatments. Talk to your doctor about what treatment options are right for you. It is important that you and your doctor weigh the risks and benefits of any medication. Although other medications are used to treat adults with Granulomatosis with Polyangiitis (GPA) (formerly known as Wegener's Granulomatosis) and Microscopic Polyangiitis (MPA), Rituxan® (rituximab) in combination with glucocorticoids is the only FDA-approved induction therapy for adults with GPA and MPA.

For important side effect information about Rituxan, please see the Important Safety Information below, and the Prescribing Information and Medication Guide.

Treatments that you and your doctor may discuss (talk with your doctor about the side effects associated with these medications):

  • Steroids: Prescribed to control inflammation and often used in combination with other medications
  • Immunosuppressive agents, such as cyclophosphamide, azathioprine and methotrexate: May be used to treat GPA and MPA, but are not FDA-approved for the treatment of GPA and MPA
  • Rituxan: When used in combination with glucocorticoids, Rituxan is the only FDA-approved induction therapy available to treat adults with GPA and MPA. Talk to your doctor about the side effects associated with Rituxan. Individual results may vary
