BioMarin: BioMarin Pharmaceutical Inc. Announces Positive Pivotal Data for PalyNZIQ (pegvaliase-pqpz) in Adolescents with Phenylketonuria

BioMarin Pharmaceutical Inc. announced that the Phase 3 PEGASUS trial evaluating PALYNZIQ® (pegvaliase-pqpz) met its primary efficacy endpoint, demonstrating a statistically significant lowering in blood Phe levels in adolescents aged 12-17 with phenylketonuria (PKU) compared to diet alone. Safety results were consistent with the known profile of the medicine. PALYNZIQ is the first and only enzyme therapy approved to treat adults with PKU. Detailed results from the PEGASUS study will be presented at an upcoming medical meeting and submitted to global health authorities starting later this year to request a label expansion for PALYNZIQ to include adolescents. PEGASUS is a Phase 3 multi-center open-label randomized controlled study evaluating the safety and efficacy of PALYNZIQ compared to diet alone in 55 adolescents aged 12-17 with phenylketonuria. The primary endpoints are change in blood Phe concentration and characterization of the safety profile in adolescents. Secondary endpoints include change in total dietary protein intake and pharmacokinetics. The study is being conducted in two parts: the primary treatment phase ranging from weeks 1-73 (Part 1), and the extension phase (Part 2), which lasts for up to an additional 80 weeks of monitoring for the PALYNZIQ arm and allows for crossover for those in the diet-only arm.
