Immune Complex Membranoproliferative Glomerulonephritis (IC-MPGN)

The purpose of this study is to evaluate the effectiveness and safety of Pegcetacoplan in patients with C3G and primary IC-MPGN in the real-world setting. This study will also assess biomarkers not routinely measured in clinical practice. Results will support the long-term evaluation of the benefit-risk profile of pegcetacoplan in a broad patient population, informing clinical decision-making.

QLS7305 injection is a chemically synthesized double-stranded small interfering RNA (siRNA) targeting complement C3, covalently linked to a ligand containing N-acetylgalactosamine (GalNAc) residues. After subcutaneous (SC) administration, it can inhibit C3 synthesis through the RNA interference (RNAi) mechanism, reduce circulating C3 protein levels, decrease the generation of complement-activated C5 convertase, and inhibit complement pathway activation. It is expected to become an effective treatment for complement-mediated kidney diseases and hematological disorders.
