Observational Study of Pegcetacoplan Treatment in Adults with Paroxysmal Nocturnal Hemoglobinuria Tracking Real-World Use and Outcomes

What this Trial Is About

This research aims to observe the real-world use and effects of pegcetacoplan in adults diagnosed with Paroxysmal Nocturnal Hemoglobinuria PNH. As a new treatment with a unique mechanism of action, pegcetacoplans effectiveness and safety in routine medical practice are being studied to provide valuable information for patients, healthcare providers, and payers. The study will also gather data on blood transfusions and healthcare resource use before and after starting pegcetacoplan. Patients who have started pegcetacoplan treatment within the past 12 months or are prescribed the drug at enrollment will be included. Data collection includes retrospective information from up to 12 months before treatment start and prospective monitoring for approximately 36 months, with the total data period extending up to about 48 months. After stopping pegcetacoplan, patients remain in the study for 8 weeks to record any adverse events. Patients continue regular clinic visits, where data from each visit will be gathered. Participants will have data collected on various health measures such as hemoglobin levels, blood markers, transfusion needs, and patient and physician treatment satisfaction at regular intervals up to 36 months. Safety and adverse events will be monitored throughout. The main outcome measured is the change in hemoglobin level from treatment start to 6 months. This long-term observational study allows for comprehensive tracking of pegcetacoplans use and effects over time in usual care settings.
