Brief summary
The current prospective, non-interventional study (NIS) being conducted under the IgNITE umbrella protocol using primary data collection (PDC), aims to enhance understanding of real-world patient profiles, treatment patterns, and clinical outcomes among patients with IgAN treated with iptacopan or atrasentan in the real-world clinical care setting immediately from the time of drug launch. Furthermore, this study is planned to contribute to a global meta-analysis, to enable further analysis with greater statistical power, as well as exploration of similarities and differences of treatment use and outcomes between countries and regions. Each patient will be observed for 24 months
