简要总结
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.
详细描述
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 aRMMs (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. Once the subject has been enrolled, the investigator (ie, subject's primary physician) will be asked to provide information about the subject's medical history, treatment(s) received to manage their blood Phe levels, treatment with pegvaliase, and concomitant medication use. The investigator will also be asked to provide evaluation of the following safety concerns: Acute systemic hypersensitivity reaction, Anaphylaxis, Angioedema, Serum sickness, Severe hypersensitivity reaction, Severe or Persistent arthralgia, Severe injection site reaction, Hypophenylalaninemia and other protocol-defined safety events, following the initiation of pegvaliase therapy. There are no protocol-mandated visits or procedures associated with this study. Enrolled subjects should be followed per routine clinical practice at the institution based upon their diagnosis, with clinical outcomes assessed at regular intervals (typically every month during the induction and titration phases of pegvaliase treatment and every 6 months once the maintenance phase is reached). No experimental treatment or assessments are planned as part of this observational study. An Independent Adjudication Committee (IAC) will periodically review protocol-defined safety events, including Acute systemic hypersensitivity reaction and Serum sickness.

结局指标
主要结局
To quantify and characterize the risk of protocol-defined safety events in incident-users receiving pegvaliase for the treatment of PKU in a real¬ world setting.
时间窗: A maximum of 10 years treatment duration.
Analyses on incident-users are considered primary. The primary analysis is the incidence rate of: Acute systemic hypersensitivity reaction Anaphylaxis Angioedema Serum sickness Severe hypersensitivity reaction Severe or Persistent (≥ 6 months) or arthralgia Severe injection site reaction Hypophenylalaninemia
次要结局
- To quantify and characterize the risk of protocol-defined safety events in subjects receiving pegvaliase for the treatment of PKU in a real-world setting.(A maximum of 10 years treatment follow up duration.)
