Summary

This study looks back at the experiences of 35 adults with a rare kidney disease called C3G who received the drug iptacopan through a special early access program in Spain. Researchers will collect information on patient health, lab results, and how the disease responds to treatment. The goal is to better understand who benefits from iptacopan and how it works in real-world settings.
