Active clinical trials for "Phenylketonurias"

The purpose of this study is to evaluate whether weekly injections of phenylalanine ammonia lyase (rAvPAL-PEG) can reduce blood phenylalanine concentrations in PKU subjects and whether repeated administration is safe.

The BMN 165 clinical development program has been designed to demonstrate the safety and efficacy of BMN 165 in reducing blood Phe concentrations in adults with PKU.

The primary objective of this study is to evaluate the efficacy of Phenoptin™ (sapropterin dihydrochloride) in reducing blood phenylalanine (Phe) levels in subjects with phenylketonuria.

The primary objective is to evaluate the degree and frequency of response to Phenoptin™ (sapropterin dihydrochloride), as demonstrated by a reduction in blood phenylalanine (Phe) level among subjects with phenylketonuria (PKU) who have elevated Phe levels. A secondary objective of this study is to evaluate the safety of Phenoptin™ treatment in this subject population, and identify individuals in this subject population who respond to Phenoptin™ treatment with a reduction in blood Phe level.

A prospective, open-label study of PKU Sphere in patients with PKU following a phenylalanine restricted therapeutic 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.

Conduct a prospective, longitudinal study to evaluate nutritional status in adults with phenylketonuria (PKU) before and during treatment with pegvaliase (Palynziq™).

PKU Sphere Liquid is a prospective, open-label, acceptability study to evaluate PKU sphere liquid in up to 15 participants aged 3 and above for the dietary management of PKU over 31 days.

The aim of this pilot study is to determine if there are any changes in brain glucose metabolism in the gray matter of patients with Phenylketonuria (PKU) and whether administration of Sapropterin (KUVAN) therapy can improve such deficits.

The main purpose is to test whether treatment with BH4-tablets can replace the protein restrictive diet in patients with mild PKU caused by a certain frequent mutation.
