Brief summary
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.
Detailed description
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 post-approval, as well as to characterise relevant biomarkers and their association with pegcetacoplan treatment. This will provide new information that was not evaluated in the clinical programme and help with understanding the long-term benefit-risk of pegcetacoplan in a broad patient population. This study will evaluate patient data prior to, during and after the use of pegcetacoplan to assess how the real-world use of pegcetacoplan impacts clinical outcomes and health care resource utilisation. This knowledge will contribute to informed clinical decision-making and provide guidance for effective disease management of patients with C3G or primary IC-MPGN.
Interventions
