IgAN is a progressive condition that causes chronic kidney disease. Over time, some patients develop end-stage kidney disease (ESKD) requiring dialysis or kidney transplant.

The purpose of this study is to see if an investigational medication is safe and effective in the treatment of IgA nephropathy.

If you are eligible for the study and decide to participate, you will come to MUSC for study visits for about 3 years. These visits will involve blood and urine samples, questions about your health, EKGs, and physical exams. Participants will be randomized in a 1:1 ratio to receive either a weight-based IV infusion of ravulizumab or placebo for 106 weeks. Depending on your response to initial treatment, there is a possibility of additional treatment. An exploratory, open-label cohort of approximately 20 participants with eGFR 20-29 mL/min/1.73m2 may also be enrolled to expand the evidence of ravulizumab in participants with advanced kidney impairment at high risk for ESKD progression.

There is no guarantee that being in this study will help you. There is no cost to participate and compensation is available for the study visits.

The purpose of this Phase III study is to evaluate the efficacy and safety of iptacopan compared to placebo (both administered in combination with standard of care) in adult participants aged at least 18 years to ≤ 60 years and adolescents (12-17 years in non-EU countries and 16-17 years in EU countries) with idiopathic IC-MPGN. The study aims to demonstrate a reduction in proteinuria and stabilization in estimated glomerular filtration rate (eGFR) in participants treated with iptacopan compared to placebo. Change in patient-reported fatigue will also be evaluated. Alternative complement pathway (AP) dysregulation is believed to underlie the clinical manifestations and progression of IC-MPGN. Serum complement (C3) and other complement pathway biomarkers will be assessed to demonstrate that iptacopan reduces AP activity and targets the underlying cause of disease.
