E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Anti neutrophil cytoplasmic antibody (ANCA) associated vasculitis. Wegener´s granulomatosis (WG) and microscopic polyangiitis (MPA) are primary systemic vasculitides associated with ANCA |
|
MedDRA Classification |
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 |
To investigate whether an MMF based induction regimen is as effective as a standard IV CYC regimen for the treatment of active ANCA associated systemic vasculitis (AASV).
|
|
E.2.2 | Secondary objectives of the trial |
To ascertain if adverse events, organ damage scores, adverse events, overall disease activity, cumulative immunosupression and steroid dosing and quality of life is better with mycophenolate mofetil compared to standard therapies.
- Time to remission (months) - Adverse events: mild/moderate/severe and infections - Relapse (relapse rates at 18 months and relapse free survival) - Cumulative dose of corticosteroids - Improvement in calculated GFR at 18 months - Cumulative vasculitis damage index (VDI) scores - Change in SF36 at 12 and 18 months - BVAS (area under curve) between entry and 18 months - ANCA status at 6 months
Optional sample collection: - Mycophenolic acid pharmacokinetics - Pharmacogenetics - Gene expression profiling |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
As specified in Amendment No.1, date february 21, 2008:
Local sub-study a: It has previously been shown that patients with active vasculitis have circulating inflammatory endothelial cells, endothelial progenitor cell dysfunction and anti-endothelial antibodies that react with human kidney microvascular endothelial cells (EC) (Holmen et al 2004, 2005, Rodriguez-Ayala 2006). We would now like to study these factors prospectively in 10-15 patients at two time points, at inclusion and at 6 months when most patients are in remission with the aim to examine their importance in active disease vs remission.
The following samples will be taken for local sub-study a at 0 and 6 months.
a) 4 x 8 mls of blood in BD vacutainer® CPTTM Cell preparation Tube with Sodium Citrate (For the separation of mononuclear cells from whole blood). b) 5 mls of blood for serum extraction
Local substudy b: CD4+ T cells which have lost expression of the costimulatory molecule CD28, e.g. Cd28null T cells are frequently found in chronic inflammatory diseases including ANCA+ vasculitis (Fasth 2004,2007. Lamprecht 2001). However, it is not understood if they are a cause or a consequence of the inflammatory processes. Here we will study both the function of these cells as well as their distribution/phenotype. Parallel studies are being performed in patients with different rheumatic diseases which will be used as disease controls. These studies will primarily be performed on peripheral blood mononuclear cells by the use of flow cytometry. For this purpose heparinized venous blood will be taken at time points when blood is also drawn for clinical use.
The following samples will be taken for local sub-study b at 0 and 6 months
• 2 x 10 mls blood at entry and at 6 months. Blood (10 ml) will also be drawn in case of relapse during 18 month follow-up.

E.4 | Principal exclusion criteria |
- Previous treatment with: 1. MMF: more than two doses ever 2. Cyclophosphamide: more than two weeks daily oral or more than 1 pulse of IV CYC (15mg/kg) 3. Rituximab or high dose intravenous immunoglobulin within the last twelve months - Active infection (including hepatitis B, C, HIV and tuberculosis) - Known hypersensitivity to MMF, AZA or CYC - Cancer or an individual history of cancer (other than resected basal cell skin carcinoma) - Females who are pregnant, breat feeding, or at risk of pregnancy and not using a medically acceptable form of contraception - Any condition judged by the investigator that would cause the study to be detrimental to the patient - Any other multi-system autoimmune disease including Churg Strauss angiitis, SLE, anti GBM disease and cryoglobulianemia - Active serious digestive system disease (e.g. inflammatory bowel disease) - Patients with imminently life threatening vasculitis (diffuse alveolar haemorrhage, intestinal perforation or major haemorrhage, cerebral vasculitis and cardiac vasculitis) - Patients with rapidly progressive glomerulonephritis and declining renal function. Defined as estimated GFR fall >20% in previous two weeks - GFR < 15mls/min at entry or on dialysis

E.5 End points |
E.5.1 | Primary end point(s) |
Proportion of patients achieving remission by 6 months. (Remission is defined as the absence of disease activity attributable to active vasculitis BVAS=0 on two occasions at least one month apart and adherence to prednisolone taper. Patients in remission require low dose immunosuppression and oral prednisolone to continue in order to maintain remission) |
