A Multi-Center, Observational Study to Evaluate the Long-Term Safety of Subcutaneous Injections of Palynziq® (Pegvaliase) in Subjects With Phenylketonuria
This is a 10-year multi-center, global, observational study to further characterize the safety profile of pegvaliase, including hypersensitivity reactions, long-term safety and tolerability, and the effectiveness of the additional risk minimization measures (aRMMs) (European Union (EU) only) in subjects receiving pegvaliase for the treatment of PKU. Subjects for whom a clinical decision has been made that they will receive pegvaliase to treat their PKU within 30 days following the date of enrollment (incident-users) or have previously started treatment with pegvaliase at the date of enrollment (prevalent-users) are eligible for participation in this study.
• Documented diagnosis of PKU per local standard of care
• Currently receiving or planned to receive pegvaliase treatment within 30 days after the date of enrollment, including subjects who previously received pegvaliase as part of the clinical development program and have completed study participation.
• Subject (or legally authorized representative) is willing and able to provide written informed consent after the nature of the study has been explained and prior to any data collection.
