A Study in Adult Patients With Paroxysmal Nocturnal Hemoglobinuria (PNH) to Evaluate How Safe Long-term Treatment With Pozelimab + Cemdisiran Combination Therapy is and How Well it Works

This study is researching an experimental treatment combination with two experimental drugs called pozelimab and cemdisiran. The study is focused on people with paroxysmal nocturnal hemoglobinuria (PNH). The aim of this study is to see how safe and effective the pozelimab + cemdisiran combination is for people with PNH in the long term. The pozelimab + cemdisiran combination may be referred to as "study drugs" in this section. This study is looking at several other research questions, including: * How effective is the pozelimab + cemdisiran combination? * What side effects may happen from taking the study drugs? * How much of each study drug is in the blood at different times? * Whether the body makes antibodies against the study drugs (which could make the drugs less effective or could lead to side effects)

A Study to Evaluate How Pozelimab + Cemdisiran Combination Therapy Works in Adult Patients With Paroxysmal Nocturnal Hemoglobinuria (PNH) Whose Current Treatment is Not Working Efficiently

This study is researching a treatment combination with two experimental drugs called pozelimab and cemdisiran referred to as "study drugs". Researchers are looking for a better way to treat Paroxysmal Nocturnal Hemoglobinuria (PNH). The aim of the study is to see how well the pozelimab and cemdisiran combination works to lower hemolysis in participants whose PNH has been not well controlled even after taking other complement component 5 (C5) inhibitors, eculizumab/eculizumab biosimilar, ravulizumab or crovalimab. The study is looking at several other research questions, including: * What side effects may happen from taking the study drugs? * How much of the study drugs are in the blood at different times? * Whether the body makes antibodies against the study drug (which could make the study drugs not work as well or could lead to side effects)

A Real World Effectiveness Study of Pegcetacoplan in Patients With Paroxysmal Nocturnal Hemoglobinuria (PNH)

This is a 36-month, long-term, multicenter, observational study designed to describe the real world effectiveness of pegcetacoplan in patients with PNH. Patients meeting the eligibility criteria will be enrolled in the study and followed prospectively for approximately 36 months. Patient data will be collected from start of pegcetacoplan treatment to end of follow-up. Retrospective data on pegcetacoplan will be captured from the time of pegcetacoplan treatment initiation. Pegcetacoplan treatment data will be collected for a minimum of approximately 36 months and up to a maximum of approximately 72 months, including retrospective period depending on when the patient started pegcetacoplan treatment. After pegcetacoplan treatment discontinuation, patients will remain in the study for 8 weeks to capture any AEs. The scope of the study is to collect both retrospective and prospective data. Baseline is defined as start of pegcetacoplan treatment. The main part of the study will be prospective,collecting data on effectiveness, safety (all AEs), patient- and clinician-reported outcomes and health care resource use.

Home Reported Outcomes in PNH

The study aims to longitudinally capture the full spectrum of symptoms, treatment utilization, and overall Health-Related Quality of Life (HRQoL) experienced by PNH patients. By primarily utilizing home reported outcomes (HRO) data on symptom burden and treatment usage, supplemented with patient-reported outcome (PRO) measures, the study seeks to establish a new real-world data (RWD) source to understand symptom variability and HRQoL among PNH patients, including those receiving orally administered iptacopan.

Global PNH Patient Registry

The primary aim of the Global Paroxysmal Nocturnal Hemoglobinuria (PNH) Patient Registry is to conduct a prospectively-planned and efficient natural history study that will result in a more comprehensive understanding of the disease and its course and pace over time. Other registry objectives include the following: * Provide a convenient online platform for participants (or caregivers) to self-report cases of PNH. * Develop a communications registry within the Global PNH Patient registry (e.g., to notify patients of research studies and clinical trials). * Characterize and describe the Global PNH population as a whole, enhancing the understanding of disease prevalence and phenotype as well as the rate of progression of disease characteristics. * Assist the PNH community with the development of recommendations and standards of care. * Be a case-finding resource to be used for researchers who seek to study the pathophysiology of PNH, retrospectively collate intervention outcomes, and design prospective trials of novel treatments.
