What this trial studies
This open-label extension study evaluates the long-term efficacy, safety, and tolerability of iptacopan in patients with C3 glomerulopathy or idiopathic immune-complex-membranoproliferative glomerulonephritis. Participants who have completed prior studies will receive iptacopan, allowing researchers to gather additional data on its effects beyond the initial treatment period. The study aims to support health authority submissions by providing comprehensive efficacy and safety information over an extended duration. It includes both adults and adolescents from ongoing Phase 3 programs.
Why it matters
Potential benefit: If successful, this treatment could significantly improve outcomes for patients with C3 glomerulopathy and IC-MPGN.
How similar studies have gone: Other studies have shown promising results with iptacopan, indicating potential for success in this approach.
