What this Trial Is About

Researchers are conducting a 10-year global, multi-center observational study to better understand the safety profile of pegvaliase, a treatment for Phenylketonuria (PKU). The study focuses on monitoring hypersensitivity reactions, long-term safety, tolerability, and the effectiveness of risk minimization measures used in the European Union. Both new users starting pegvaliase within 30 days of enrollment and those who have already been receiving pegvaliase can participate. Participants in this study will not receive any experimental treatments or undergo special procedures as part of the trial. Instead, their usual pegvaliase treatment and clinical care will continue as normal. Information about their medical history, pegvaliase use, other medications, and safety concerns such as allergic reactions and injection site issues will be collected by their primary physicians. Safety events will be reviewed periodically by an independent committee. Participants are followed according to routine clinical practice, with clinical outcomes assessed regularly, typically monthly during initial treatment phases and every six months during maintenance. The study measures risks of specific safety events over up to 10 years of pegvaliase treatment in a real-world setting. There are no mandatory study visits, and all data collection is based on regular medical care visits.
