Plain English summary of protocol
Background and study aims
IgA nephropathy, also known as Berger's disease, is a kidney disease that occurs when an antibody called immunoglobulin A (IgA) builds up in the kidneys. This results in local inflammation that, over time, can hamper the kidneys' ability to filter waste from the blood.
Treatment of IgA nephropathy (IgAN) is a matter of debate and while corticosteroids remain the most effective in preventing disease progression, their use is limited by important side effects. This study aims to evaluate the efficacy of budesonide (Budenofalk®) in the treatment of patients with IgA Nephropathy.
Who can participate?
Patients aged 18 years or above with IgA nephropathy and persistent proteinuria.
What does the study involve?
Patients receive treatment with Budesonide for up to 36 months.
What are the possible benefits and risks of participating?
The benefit include the possibility of being treated and followed in a tertiary clinic, with high experience in managing the patients with IgA Nephropathy. This study doesn’t carry any risk associated with the participation, other than that related to the risk associated with diagnostic procedures (percutaneous kidney biopsy) and the possibility of minimal steroid-related side-effects.
Where is the study run from?
Fundeni Clinical Institute, Department of Nephrology (Romania)
When is the study starting and how long is it expected to run for?
March 2020 to December 2024

| Scientific title | An open-label study evaluating the efficacy and safety of budesonide in the treatment of patients with immunoglobulin A nephropathy |
| Study acronym | BUDIGAN |
| Study objectives | Gut-associated lymphoid tissue production (GALT) of the immunoglobulin A1 with a characteristic galactosylation defect in the hinge region of the molecule is the first pathogenic event in the course of IgA nephropathy. Targeting GALT dysregulation with a pH-modified formulation of budesonide with a maximum release in the distal ileum and proximal colon offers the premise of a safer approach than systemic corticosteroids for the treatment of IgA nephropathy. |
| Ethics approval(s) | Approved 18/12/2019, The Ethics Council of Fundeni Clinical Institute (Sos. Fundeni, Nr. 258, Sector 2, Bucharest, 022328, Romania; +40 212750500; etica@icfundeni.ro), ref: 1975 |
| Health condition(s) or problem(s) studied | Immunoglobulin A nephropathy |
| Intervention | Patients receive treatment with budesonide at a dose of 9 mg/day for the first 12 months, subsequently tapered to 3 mg/day for another 12-24 months. |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Phase IV |
| Drug / device / biological / vaccine name(s) | Budesonide (Budenofalk®) |
| Primary outcome measure | At baseline and 36 months: 1. Estimated glomerular filtration rate 2. Extent of proteinuria and hematuria 3. MESTC score assessed by kidney biopsy |
| Secondary outcome measures | Incidence of budesonide-related adverse events over the 36 months |
| Overall study start date | 01/03/2020 |
| Completion date | 31/12/2024 |
