Novartis Pharmaceuticals
Summary
A study to investigate the impact of iptacopan treatment on the underlying immunopathology in patients with IgAN by assessing changes in key clinical and molecular markers from baseline to 9 months. The study aims to provide insights into the treatment's systemic and kidney-specific aspects by quantifying the change in mesangial C3c containing fragments deposition, as an indicator of complement activation, and evaluating a variety of biomarkers related to kidney function, damage, and disease progression, including but not limited to Oxford MEST-C score.
Description
The study comprises of a screening period followed by a baseline visit, at which a baseline kidney biopsy will be performed. Eligible participants included in the study will receive iptacopan 200 mg b.i.d for a 9-month treatment period. Dose adjustment of iptacopan is not allowed during the treatment period. At Month 9, upon completion of the treatment period, a follow up biopsy is performed for all participants at the time of end of study (EOS).
