Filter by:The purpose of this prospective, observational study is to evaluate the tolerability and acceptability of phenylalanine-free protein substitute tablets for young children with PKU aged of 7 years or older.
PURPOSE OF STUDY: To determine if a non-invasive skin stripping technique can be used to detect individuals with phenylalanine abnormalities, and to monitor dietary and/or drug effects over time.
The aim of this study is to demonstrate that a new protein substitute is acceptable and well tolerated in children with PKU.

lnborn errors of metabolism (IEM) are a heterogeneous group of rare, sometimes debilitating or even fatal diseases . In IEM, both definition and assessment of meaningful outcome parameters is often extremely difficult resulting in a limited body of evidence. Limited evidence results in weak recommendations which are perceived as unbinding and thus sustains heterogeneous study designs, choice of outcomes and interventions again producing non-uniform data. The goal of the current study is to identify and select reliable instruments, that measure patients' and their parents' perception about relevant (social, emotional, cognitive and physical) aspects in their lives. This set of instruments will secure the comparability of future research findings. Furthermore this instruments will improve the screening of paediatric IEM patients regarding their need for additional (psychosocial or consultative) support in daily hospital routine.
Phenylketonuria (PKU) is a rare inherited metabolic disorder, where subjects are born with a genetic deficiency in the phenylalanine hydroxylase enzyme (PAH), which leaves them unable to convert Phenylalanine (Phe) into Tyrosine (Tyr). PKU patients have specific dietary needs and must follow a restrictive diet in the aim of preventing toxic levels of the amino acid phenylalanine (Phe) accumulation.
This study is an international, multi-center, randomized, double-blind, placebo-controlled, two-treatment, two-period cross-over study to evaluate the pharmacodynamics, safety, tolerability and pharmacokinetics of a single oral dose of CDX-6114 in patients with phenylketonuria (PKU).
Randomised controlled trial with a crossover design. For early and continuously treated patients with phenylketonuria (PKU) that are adherent. Two 12-week periods where patients consume either casein glycomacropeptide (CGMP) based protein substitute or a free amino acid (AA) based protein substitute. 4 week wash out period in between. The protein substitutes will be consumed daily together with the patient's regular low protein diet.
Phenylketonuria is the most common inherited metabolic disease in France and is screened for neonatal exposure. Management consists of a strict and restrictive hypoproteic diet and the intake of amino acid substitutes and dietary supplements free of phenylalanine.One of the major difficulties, which is the source of many treatment failures, is the inappetence of the amino acid supplements required during a strict hypoproteic diet. New formulations, Glycomacropeptides (GMP), have recently appeared and are considered more palatable than conventional amino acid mixtures.
A retrospective study to collect the effectiveness and safety data of the past treatment with KUVAN in Chinese patients with HPA caused by BH4 deficiency. The data was collected from relevant past medical history and past clinical and safety assessments.
