Filter by:Ajinomoto Cambrooke has developed a PKU protein substitute that is a proprietary blend of purified Glycomacropeptide (GMP) and essential amino acids, under the brand name Glytactin®. One serving of such Glytactin® products contains 20mg or less of Phenylalanine (Phe). The aim of the proposed study is to use this purified GMP-AA-based protein substitute, with less Phe per gram of protein equivalent than other commercially available products, in children with PKU at 100% of their protein substitute intake and evaluate its efficacy and the change in blood Phe in comparison to Phe-free L-AA-based protein substitutes.
Children with phenylketonuria (PKU) are treated with a special diet supplemented with a synthetic protein based on amino acids. These have a poor taste and are inefficiently used by the body. A different type of synthetic protein, called glycomacropeptide is being tried in PKU. It tastes better than amino acids but it requires the addition of some extra amino acids which may worsen how well it is absorbed compared with traditional amino acid supplements. We will perform a 3-part trial in healthy adult volunteers to compare amino acids vs glycomacropeptide protein with a 'normal protein' (casein) to examine the absorption properties of these proteins. Volunteers will take one dose of each of the protein sources on 3 different days. Blood and urine samples will be collected examining the rate of absorption of amino acids over 5 hours on each study day.
This is a Phase 3 open-label randomized controlled study enrolling approximately 54 adolescents with PKU. The study is designed to assess the safety and efficacy of pegvaliase injections.
This research investigates the effects of combining a phenylalanine restricted diet (usual care) with LNAA supplementation (adjuvant LNAA) in well-controlled adults with classical PKU. The hypothesis is that symptoms are improved in well-controlled patients who receive adjuvant LNAA therapy compared with diet monotherapy. Six symptomatic classical PKU adults will be enrolled to test the hypothesis in a small series of N-of-1 randomized controlled trials over 18-weeks. All assessments will be collected in patient's homes. A 3-month follow-up period will assess the longer-term effects of adjuvant LNAA in patients who show clinical benefit at the end of the intervention period.
PKU explore France is an exploratory study to evaluate the acceptability of PKU explore, a food for special medical purposes, for use in the dietary management of phenylketonuria in infants from 6 months to 3 years of age, assessing participant adherence, GI tolerance, phe levels, growth and product palatability.
This is a Phase 1/2, open-label, dose escalation study to evaluate the safety, efficacy and tolerability of BMN 307 in adult PKU subjects with PAH deficiency. Participants will receive a single administration of BMN 307 and will be followed for safety and efficacy.
This is a Phase 3b, multicenter, open-label, randomized, controlled study to evaluate efficacy, safety and population pharmacokinetics of sapropterin dihydrochloride (Kuvan®) in less than 4 year-old infants and children with Phenylketonuria (PKU).
