Filter by:Three new protein substitutes have been developed to help with compliance in PKU and TYR patients, which are powdered protein substitutes, low in Phe and, low in Phe and Tyr respectively, with a mixed balance of glycomacropeptide (GMP), essential and non-essential amino acids, carbohydrates, fats and micronutrients for the dietary management of PKU and TYR. This series of case-studies will evaluate the acceptability, compliance, gastrointestinal tolerance and safety of the three GMP-based products for PKU and TYR in 45 patients with PKU and TYR, in both adults and children over 3 years (15 patients per product). The case study will last 29 days in total, including a 1-day baseline period followed by a 28-day intervention period. The case studies will be conducted across multiple specialist metabolic centres in the UK, to meet the UK ACBS and GMS requirements for acceptability studies. A series of case studies is undertaken due to the rarity of these conditions and the difficulty in recruiting these patients to trials.
For 28 days, 20 patients with tyrosinaemia will take TYR sphere as part of the usual dietary management of their condition. Patients will record their adherence to recommended intakes each day, gastrointestinal symptoms (if any) experienced each day of weeks one and four, and the palatability of the product at the end of the trial. Metabolic control will be evaluated by dried blood spots collected during the Baseline and End of Study visits, and weekly during the 28 days of the study itself. Trial data will be used in an application to make TYR sphere available via the NHS.
The purpose of this study is to determine whether Nitisinone 10 mg Tablets (Test Product 1) and Nitisinone 10 mg Tablets High Compritol (Test Product 2) are bioequivalent to the reference product Orfadin 10 mg capsules.
The purpose of this study is to determine whether Nitisinone 10 mg Tablets (Test Product 1) and Nitisinone 10 mg Tablets 'Baked' for 6 months @ 40°C/75% RH (Test Product 2) are bioequivalent to the reference product Orfadin 10 mg hard capsules.
The purpose of this study is to compare the bioavailability of the Test Product, Nitisinone 10 mg Tablet, under fasting and fed conditions (food-effect).
The purpose of this study is to look at the steady-state serum concentrations of nitisinone when switching from twice daily and once daily dosing.
The purpose of this study is to look at the long term safety profile of Orfadin treatment in patients suffering from hereditary tyrosinemia type 1 (HT-1). Patients included in the study will use Orfadin according to normal clinical practice.
The purpose of this study is to verify that pediatric patients, especially those who are not old enough to swallow capsules, accept the taste and palatability of a new suspension.
OBJECTIVES: I. Assess the safety and efficacy of NTBC in children with tyrosinemia I. II. Evaluate the effects of NTBC on survival, rate of neurologic crises, improvement in renal tubular damage, reduction in the need for liver transplantation, and reduction in the development of hepatocarcinoma in these patients.
OBJECTIVES: Assess whether 2-(2-nitro-4-trifluoromethylbenzoyl)-1,3-cyclohexanedione (NTBC) at 0.6 mg/kg per day prevents liver failure in at least 1 patient with tyrosinemia type I.
