Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study consists of two phases: a 6-month remission induction phase, followed by a 12-month remission maintenance phase. All participants will receive at least 1 g of pulse intravenous methylprednisolone or a dose-equivalent of another glucocorticoid preparation. Depending on the participant's condition, he or she may receive up to 3 days of intravenous methylprednisolone for a total of 3 g of methylprednisolone (or a dose-equivalent). During the remission induction phase, all participants will receive oral prednisone daily (1 mg/kg/day, not to exceed 80 mg/day). Prednisone tapering will be completed by the Month 6 study visit.
Next, participants will be randomly assigned to one of two arms. Arm 1 participants will receive rituximab (375 mg/m\^2) infusions once weekly for 4 weeks and cyclophosphamide (CYC) placebo daily for 3 to 6 months. Arm 2 participants will receive rituximab placebo infusions once weekly for 4 weeks and CYC daily for 3 to 6 months. During the remission maintenance phase, participants in Arm 1 will discontinue CYC placebo and start oral azathioprine (AZA) placebo daily until Month 18. Participants in Arm 2 will discontinue CYC and start AZA daily until Month 18. Participants who fail treatment before Month 6 will be crossed over to the other treatment arm unless there are specific contraindications. Participants in either group who reach clinical remission before they complete 6 months of therapy may switch from CYC/placebo to AZA/placebo if directed by their physicians.
All participants will be followed for at least 18 months. Initially, study visits are weekly, progressing to monthly and then quarterly visits as the study proceeds. Blood collection will occur at each study visit.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Diagnosis of Wegener's granulomatosis or microscopic polyangiitis according to the definitions of the Chapel Hill Consensus Conference
* Newly diagnosed patient of Wegener's granulomatosis or microscopic polyangiitis OR must be experiencing a disease flare characterized by: (a) active disease with a Birmingham Vasculitis Activity Score for Wegener's granulomatosis (BVAS/WG) of 3 or greater that would normally require treatment with CYC; OR (b) disease severe enough to require treatment with CYC; OR (c) must be positive for either PR3-ANCA (ANCA directed against proteinase 3) or MPO-ANCA (ANCA directed against myeloperoxidase)at the screening
* Willing to use acceptable forms of contraception for the duration of the study and for up to 1 year after stopping study medications
* Willing to report pregnancies (female participants or male participants' partners) occurring at any time during the study and for up to 1 year after stopping study medications
* Parent or guardian willing to provide informed consent, if applicable
Exclusion Criteria
* Have limited disease that would not normally be treated with CYC
* Requires mechanical ventilation because of alveolar hemorrhage
* History of severe allergic reactions to human or chimeric monoclonal antibodies

* History of or current hepatitis B or C infection
* HIV (human immunodeficiency virus) infected
* Acute or chronic liver disease that, in the opinion of the investigator, may interfere with the study
* History of or active cancer diagnosed within the last 5 years. Individuals with squamous cell or basal cell carcinomas of the skin and individuals with cervical carcinoma in situ who have received curative surgical treatment may be eligible for this study.
* History of anti-glomerular basement membrane (anti-GBM) disease
* Other uncontrolled disease, including drug and alcohol abuse, that may interfere with the study
