Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
After the patients' disease is controlled (in remission), we will reduce the dosages of the standard medications to lower the risk of side effects associated with these drugs. During the study, we will collect and save blood and tissues samples from patients and use the samples to address other medical questions, such as the cause of WG and factors that lead to disease progression.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The trial is a phase II/III randomized, double-masked, multicenter trial with a parallel treatment design. We will assign patients randomly to either etanercept or placebo in an assignment ratio of 1:1. In addition to either etanercept or placebo, we will treat all patients with standard drug regimens for WG according to the severity of their disease. We will treat those with limited WG with methotrexate and corticosteroids, and those with severe WG with cyclophosphamide and corticosteroids. After the patients' disease is controlled with therapy (i.e., the standard treatment regimen plus either etanercept or placebo), we will taper the standard medications according to regimens designed to ensure patient safety, diminish morbidity associated with the standard medications, and test the efficacy of etanercept in sustaining disease remissions.
The principal outcome measure in this trial is the number of patients in the two treatment arms who achieve sustained remissions measured by the Birmingham Vasculitis Activity Score for WG (BVAS). The sample size is 181 patients recruited at eight clinical centers in the United States. We will stratify randomization by clinic and disease severity (limited versus severe). Every patient enrolled will have a BVAS of at least three, insuring unequivocally active disease.
We will follow all randomized patients, regardless of whether or not they remain on their assigned treatments, until the common closing date of the trial, defined as 12 months after enrollment of the last patient. We will perform the primary analyses on an intention-to-treat basis.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Diagnosis of WG, excluding infections, malignancies, systemic autoimmune disorders, and other forms of vasculitis that may mimic WG.
* At least two of the five modified American College of Rheumatology (ACR) criteria for a diagnosis of WG. The modified ACR criteria are: (1) nasal or oral inflammation, defined as the development of painful or painless oral ulcers or purulent or bloody nasal discharge; (2) abnormal chest radiograph, defined as the presence of nodules, fixed infiltrates, or cavities; (3) active urinary sediment, defined as microscopic hematuria (\> 5 red blood cells per high-power field) or red blood cell casts; (4) granulomatous inflammation on biopsy, defined as histologic changes showing granulomatous inflammation within the wall of an artery or in the perivascular or extravascular area (artery or arteriole); and (5) positive serum ELISA for ANCAs (anti-neutrophil cytoplasmic antibodies) directed at PR-3.
* Birmingham Vasculitis Activity Score (BVAS) score 3 or greater within 28 days of randomization. This may include either the presence of one or more major items (3 points each) or the presence of three or more minor items (1 point each).
* Willingness and ability, with the assistance of a caregiver if necessary, to comply with treatment and followup procedures.
* Willingness of men and women of childbearing potential to practice an adequate method of birth control during the study and for 3 months afterwards.
* Willingness to limit alcohol consumption to one alcoholic drink per week while taking methotrexate.
* Willingness to refrain from breast-feeding during the study and for 3 months afterwards.
* Collection of all baseline data within 14 days prior to randomization.
* Signed consent statement.
Exclusion Criteria
* White blood cell count less than 4,000/mm cubed or a platelet count less than 120,000/mm cubed.
* Creatinine greater than 2.0 mg/dL secondary to non-WG causes (e.g., hypertensive nephropathy) for a patient with limited disease.
* Known acute or chronic liver disease.
* History of multiple sclerosis or other neurological symptoms suggesting a demyelinating syndrome.
* Current evidence of malignancy or malignancy diagnosed within 5 years of study entry. Patients with squamous or basal cell carcinomas of the skin may be enrolled if they have received curative surgical treatment.
* Positive serum pregnancy test for women of childbearing potential.
* Previous treatment with specific therapies directed against tumor necrosis factor, e.g., etanercept or infliximab.
