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.
The purpose of this study is to determine if zigakibart is safe and effective for long-term use in patients with immunoglobulin A nephropathy (IgAN). This is an extension study for patients who have already completed an another zigakibart study.
A central goal of this data repository is to collect data from a large population of subjects with a variety of renal disease states. Cohorts will include subjects with diabetes, inflammatory/autoimmune and transplant related renal conditions. Additionally, the repository will have the capacity to store biospecimens and electronic data in control subjects without established renal disease. This initiative will provide an opportunity to compare data from various disease states and controls with the objective of determining clinical and biological factors that predict disease progression, response to therapy and identify discriminating noninvasive clinical and biological features that predict renal biopsy findings.
The purpose of this study is to evaluate the safety and tolerability of atacicept in adult and adolescent participants and to measure the effect in reducing proteinuria and preserving renal function.
