ClinicalTrials.gov Identifier:	NCT00468208

Purpose

Wegener's granulomatosis (WG) is a rare disease that causes inflammation of blood vessels, or vasculitis. It may involve many different parts of the body, but typically affects the upper and lower respiratory tract and kidneys. The purpose of this study is to determine the safety and effectiveness of the medication abatacept in treating adults with mild relapsing WG.

Arms	Assigned Interventions
1: Experimental Participants will receive abatacept intravenously at study visits on Days 1, 15, and 29, and then once a month thereafter for a total of 6 to 18 months.	Drug: Abatacept A participant's abatacept dose will depend on body weight and will remain the same throughout the study: 500 mg of abatacept for body weight less than 60 kg 750 mg of abatacept for body weight between 60 and 100 kg 1000 mg of abatacept for body weight greater than 100 kg Abatacept will be administered in a 30-minute intravenous infusion.

Detailed Description:

Current standard treatment for WG involves various medications and is based on disease severity. Unfortunately, more than 50% of people experience a relapse after remission, placing them at risk for additional organ damage and medication toxicity. To prevent this, safer and more effective treatments for mild relapses are needed. Several studies have shown that activated T cells, a type of white blood cell important in regulating immune responses, play a role in WG. Abatacept, an immunoglobulin-based medication approved by the FDA to treat rheumatoid arthritis, acts by preventing T-cell activation and may be useful in treating mild relapses of WG. The purpose of this study is to determine the safety and effectiveness of abatacept in treating adults with mild relapsing WG.

Participation in this study may last between 7 and 24 months. Participants will receive abatacept intravenously at study visits on Days 1, 15, and 29, and then once a month thereafter. A participant's abatacept dose will depend on body weight and will remain the same throughout the study. Participants who are receiving glucocorticoids and/or certain maintenance immunosuppressive medications at study entry will remain on these medications during the study. All study visits will include medication review, physical exam, blood and urine collection, and questionnaires. A chest x-ray, computed tomography (CT) scan of the chest and sinuses, and lung function testing may occur at some study visits. Participants whose symptoms have not improved by Month 2 will stop receiving abatacept. All participants will attend three follow-up study visits that will occur 1, 3, and 6 months after the end of treatment.

Criteria

Inclusion Criteria:

Diagnosis of WG, meeting at least 2 of the 5 American College of Rheumatology (ACR) criteria. More information about this criterion can be found in the protocol.
Relapse of WG in which 1) no other cause can be attributed, 2) the symptoms call for usual treatment consisting of a reinitiation or increase in glucocorticoids and/or an increase or addition of a second immunosuppressive agent other than cyclophosphamide, OR 3) disease activity is confined to one or more of the following (more information about this criterion can be found in the protocol):
1. Sinonasal disease
2. Oral mucosa ulceration
3. Skin disease
4. Musculoskeletal disease
5. Pulmonary parenchymal disease
Willing and able to undergo treatment and attend follow-up visits
Willing to use effective forms of contraception throughout the study

Exclusion Criteria:

Disease involvement that does not meet the criteria for mild disease. More information about this criterion can be found in the protocol.
Disease activity that would usually be treated first with cyclophosphamide
