E.1.2 | Term | Anti-neutrophil cytoplasmic antibody positive vasculitis |

E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of this study is to test a drug called belimumab (which has been approved for use in different medical conditions to the one being studied here) in patients with active ANCA-associated vasculitis. We want to find out if giving belimumab in addition to the current standard treatment will lead to improvement of the disease. |
|
E.2.2 | Secondary objectives of the trial |
1. To investigate any changes in the antibodies (proteins made in the body in response to foreign substance) that are suspected to cause the AAV in patients who receive belimumab and in patients who receive a placebo (a medication that looks the same but does not have any drug in it).
2. To investigate the changes in any white blood cell values.
3. To investigate if the addition of belimumab to the standard treatment is a more effective way to treat AAV.
4. We want to find out what effects, good or bad, the addition of belumimab to the standard treatment has on people with AAV.
