Exclusion criteria
Exclusion criteria: 1. Subjects with severe life-threatening disease, i.e. lung haemorrhage at the time of presentation, renal impairment with SCr>150 mcmol/l, or severe CNS dysfunction thought to be due to vasculitis 2. Subjects with current symptoms of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, pulmonary, cardiac, neurological, or cerebral disease, or other medical conditions that, in the opinion of the investigator, might place the subject at unacceptable risk for participation in this study. 3. Subjects with any other non-vasculitic multisystem autoimmune disease. 4. Subjects with any serious acute bacterial infection unless treated and completely resolved with antibiotics prior to enrollment 5. Subjects with any severe chronic or recurrent bacterial infection, e g. bronchiectasis, osteomyelitis, chronic pyelonephritis 6. Subjects with Hepatitis B or C or HIV. 7. Subjects with Herpes zoster infection that resolved less than 2 months prior to enrollment. 8.

Subjects participating concurrently in another clinical trial. 17. Subjects with a history of intolerance to methotrexate. 18. Subjects who have at any time received treatment with abatacept. 19. Subjects who have received treatment with any investigational drug within 28 days (or less than 5 terminal half-lives of elimination) of the Day 1 dose. 20.

|---|---|
| Main Objective: To assess the relapse rate (defined by clinical and biochemical parameters) over 24 months in patients with acute AAV presenting at first diagnosis of relapse, after 12 months of treatment with abatacept in combination with steroids and methotrexate or placebo in combination with steroids and methotrexate. ; Secondary Objective: To assess the clinical efficacy of abatacept combined with MTX + steroids vs placebo and MTX + steroids by measuring: 1. The sustained remission rate 2. Time to remission 3. The average steroid dosage at 6, 12, 18 and 24 months in abatacept and placebo groups respectively 4. Time to ANCA negativity by immunofluorescence or negative anti-PR3 or anti-MPO Ab test by ELISA. 5. Proportion of patients defaulting to cyclophosphamide therapy. 6. Proportion of patients unable to stick with trial protocol. 7. Degree of chronic disease activity 8. Health related quality of life To assess the safety and tolerability of abatacept in this study population, evaluated by number of adverse events ; Primary end point(s): Response to treatment measured by: Relapse rates in patients who have achieved remission over 24 month study period. Proportion of patients in sustained remission at 6, 12, 18 and 24 months; time to remission; The average steroid dosage at 6, 12,18 and 24 months; Time to ANCA negativity by immunofluorescence or negative anti-PR3 or anti-MPO Ab test by ELISA; Urinary MCP-1 measurement to assess disease activity in those with kidney disease. In both groups, disease will be monitored using the well established and validated BVAS 2003, in conjunction with biochemical, immunological, radiological and other physiological parameters, which we regularly use to assess disease activity.
