Biomarkers for the Progression of IgA Nephropathy

Status Completed

Clinical Trial Summary

IgA nephropathy (IgAN) is the most prevalent primary glomerular disease worldwide and an important cause of end stage renal disease. IgAN has an incidence of 8-25 new cases/year/per million age-related population in adults and 3-5/new cases/year/per million age-related population in children and progresses to need of renal replacement treatment in 5-15% at 10 years and in about 20% at 20 years. The variability of the clinical course anticipates different treatment options. There is an absolute need of validated biomarkers to predict risk of progression and indication for treatment at early stages, when lesions can be reversible. This study aimed to evaluate IgAN progression and its histological and clinical correlates.

Clinical Trial Description

IgA nephropathy is the most prevalent primary glomerular disease worldwide and an important cause of end stage renal disease. Clinical course varies from long term stable renal functions with minimal proteinuria and microscopic hematuria to rapidly progressive glomerulonephritis with crescents on renal biopsy which progresses to end stage renal disease in a very short time.

In current practice the diagnosis is made with renal biopsy. A less invasive procedure for diagnosis is not present and no serum biomarkers for clinical follow-up, treatment response and prognosis are available. For that reason follow-up of the disease is enabled with indirect markers of renal function like proteinuria, serum creatinine and glomerular filtration rate. These markers are not specific for IgA nephropathy. The lack of disease specific markers hinders the standardization of patient follow-up and treatment. Development of specific and sensitive, repeatable, histopathological and clinical markers for diagnosis, follow up and treatment response in IgA nephropathy the most prevalent primary glomerular disease affecting many patients worldwide will offer prospects of diagnosis and improved prognostication. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
