PRIMARY outcome

Timeframe: The Outcome Measure Data Table below uses the 'analysis visit' as defined by the mapping rule in the SAP. The last Phe measurement was mapped to 'analysis visit' week 121. The actual date of the last Phe measurement was day 836 (approximately Week 119).

Population: Efficacy population consisted of all subjects receiving at least one dose of pegvaliase during the study and having a post-treatment blood Phe concentration measurement.

Change in blood phenylalanine (Phe) concentration from Parent Study baseline (naïve/pretreatment).
