Overview
Brief Summary
This is a Phase 3 open-label randomized controlled study enrolling approximately 54 adolescents with PKU. The study is designed to assess the safety and efficacy of pegvaliase injections.
Detailed Description
This Phase 3 multicenter study is designed to evaluate the safety and efficacy of pegvaliase administered daily to adolescents (ages 12 to 17 years old (US), inclusive, and 12 to 15 years old (EU), inclusive 12-17) with phenylketonuria (PKU). Participants will be randomized in a 2:1 ratio to the active (pegvaliase) and control (diet-only) treatment arms, respectively, with 36 participants receiving pegvaliase and 18 participants managing their PKU with diet alone.

Arms & Interventions
Pegvaliase
Intervention: Pegvaliase
Diet Only
Participants will be managing their PKU with diet alone. Participants in the diet-only control arm will be required to maintain and adjust dietary and medical protein food intake through Week 72, initiating pegvaliase treatment beginning Week 73 and, from Weeks 73 through 215.
Intervention: Diet Only
