Study information
Scientific title
Acronym
MIgAN
Study hypothesis
With our investigator-initiated MIgAN study, we should like to test two hypotheses:
1. Further loss of renal function will occur in cases with progressive type two immunoglobulin A nephritis (IgAN) even after immunosuppressive induction therapy and while on angiotensin converting enzyme (ACE) inhibitor therapy
2. Sequential maintenance immunosuppression with mycophenolate and low dose prednisolone is able to prevent this loss better than ACE inhibition alone
Ethics approval
Ethics approval received from the University of Ulm Ethics Committee on the 9th April 2008 (ref: 13/08).

Condition
Mesangioproliferative IgA glomerulonephritis
Intervention
After enrolment phase, two patient groups are randomly assigned:
1. The mycophenolate group is treated with daily 2 x 360 mg oral mycophenolate combined with 2 x 2.5 mg oral prednisolone and the supportive standard therapy
2. The control group is treated with the supportive standard therapy alone consisting with an angiotensin-converting-enzyme inhibitor (ACEi) and/or an angiotensin receptor blocker (ARB)
The maximum duration of treatment is 36 months and the total duration of follow-up of all arms is 36 months.

Phase
Not Specified
Drug names
Mycophenolate, prednisolone
Primary outcome measures
The frequency of a GFR loss greater than 20% in the mycophenolate group and in controls. The loss is estimated by the difference from the best GFR after induction therapy. The primary end-point will be measured at the end of month 36.
Secondary outcome measures
1. Urinary protein/creatinine ratio
2. Need for any further temporary or permanent medication (antihypertensives, antidiabetics, antiinfectives, etc.)
3. Hospitalisation
4. Dialysis
5. Death
All secondary end-points will be measured every three months in each patient.
