Safety and Efficacy Study of NGGT002 in PKU Adult Subjects
This investigator initiated trial is an open-label, dose escalation study to evaluate the safety, tolerability and efficacy of NGGT002, an AAV derived investigational gene therapy product expressing human PAH enzyme in adult Phenylketonuria (PKU) subjects with PAH deficiency. All participants will receive a single administration of NGGT002 and will be …
AAV Gene Therapy Clinical Study in Adult Classic PKU (PHEdom)
This is a Phase 1/2, open-label, multiple-center, dose escalation and cohort expansion study to evaluate the safety and efficacy of NGGT002 in adult subjects with classic Phenylketonuria (PKU). NGGT002 is an rAAV8 based vector carrying a functional copy of the human PAH gene. Participants will receive a single administration of …
Development of Novel Psychological Assessment Tools and Anxiety Intervention for Phenylketonuria
While previous PKU intervention research has largely focused on pharmacological treatment of elevated Phe levels, the adaptation of evidence-based psychosocial therapy holds promise for addressing cognitive and psychological symptoms and significantly improving quality of life. Study goals include: (1) to demonstrate the efficacy and feasibility of a short-term skills-based intervention …
A Phase 2 Study of JNT-517 in Adolescent Participants With Phenylketonuria
The goal of this Phase 2, randomized study is to assess the safety, tolerability, and pharmacokinetics (PK) of oral JNT-517 in adolescents (12 to less than 18 years of age) with PKU. Participants will receive either JNT-517 or placebo and will be blinded to their treatment assignment. Participants will have …
Phe for Me? The Effects of L-Phe on PKU Carriers and Non-carriers
This is a clinical intervention study of PKU carriers (cases) and non-carriers (controls). Upon completing the informed consent process, participants will complete baseline measures of chronic mental health prior to the intervention (PHQ-9, GAD-7, BIS-11). Participants will attend the Human Nutraceutical Research Unit (HNRU) at the University of Guelph, fasted, …
Educational, Social Support, and Nutritional Interventions and Their Cumulative Effect on Pregnancy Outcomes and Quality of Life in Teen and Adult Women With Phenylketonuria
The purpose of this project is to study the effectiveness of teaching teens and young women with Phenylketonuria (PKU) or Maple Syrup Urine Disease (MSUD) about their disease and nutrition related issues in a camp environment. It will also look at pregnancy outcome results in women with PKU who attended …
A Global, Multicenter Study to Assess Maternal, Fetal and Infant Outcomes of Exposure to Palynziq® (Pegvaliase) During Pregnancy and Breastfeeding
This is a Phase 4 observational study designed to assess the impact of Palynziq ® (pegvaliase) treatment in pregnant women with PKU and on their offspring who were exposed to pegvaliase at any time during pregnancy and breastfeeding.
Nutritional Impacts of Palynziq on Patients With Phenylketonuria (PKU)
Phenylketonuria (PKU) is an inherited metabolic disorder that impairs the metabolism of the essential amino acid phenylalanine (Phe). Without stringent dietary control, Phe accumulates in the blood and brain of PKU patients, leading to severe cognitive deficits. Achieving metabolic control, defined as blood Phe levels within the range of 120-360 …
Brain Aging in Phenylketonuria
Background: Historically, the primary goal in managing phenylketonuria (PKU) has been to prevent severe and irreversible intellectual disability, as well as to address nutritional deficiencies that could lead to growth impairments or intellectual decline. Since the introduction of neonatal PKU screening in the mid-1960s, early treatment during childhood with a …
A Long-term, Post-marketing Safety Study of Palynziq in Patients With PKU (PALace)
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 …
