Active clinical trials for "Phenylketonurias"

This is a Phase 3 open-label extension study enrolling adult patients with PKU who were previously treated with pegvaliase in Studies PAL-003 (NCT00924703) or 165-302 (NCT02468570). The study is designed to evaluate the long-term safety and efficacy of pegvaliase administered at doses > 40 mg/day to 60 mg/day.

This Phase 1/2a, first-in-human, oral single and multiple dose-escalation, randomized, double-blinded, placebo-controlled study is evaluating SYNB1618 in healthy volunteers (HV) and subjects diagnosed with phenylketonuria (PKU), a rare inherited metabolic disorder that occurs in people who are missing an enzyme that the body needs to use phenylalanine (Phe). Eligible subjects receive investigational product (IP) in the clinic and undergo safety monitoring, evaluations, and subsequent follow-up after IP administration.

This is an open-label, non-comparative, Phase 3 study to evaluate the degree, frequency of response and safety of Kuvan® (sapropterin dihydrochloride) in subjects aged 4 to 18 years who have phenylketonuria and with elevated blood phenylalanine level of greater than or equal to 450 micromole per liter.

The BMN 165 clinical development program has been designed to demonstrate the safety and efficacy of BMN 165 in reducing blood Phe concentrations in patients 18 to 70 years old with hyperphenylalaninemia due to PKU. Study BMN 165-301 is a Phase 3, open-label, randomized study designed to further characterize the safety of BMN 165 during two induction, titration, and maintenance dose regimens in adults with PKU who have not had previous exposure to BMN 165 (naive). Subjects will be randomized (1:1) to titrate up to one of two dose regimens. Other key features of this study are the dose regimens chosen for induction and titration; the study duration; self administration of study drug; and the chosen tertiary objectives.

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).

The purpose of this study is to evaluate the effect of daily administration of rAvPAL-PEG on the reduction of blood Phe concentrations in subjects with PKU.

The purpose of this study is to assess the safety and tolerability of injections of rAvPAL-PEG in subjects with PKU.

The investigators will investigate the effect of blood phenylalanine on Kuvan responsiveness in the same patients with PKU when their blood phenylalanine concentrations are altered by diet. Lowering blood phenylalanine concentrations in Kuvan non-responsive patients with PKU will increase the frequency of Kuvan responsiveness.

The purpose of this study is to evaluate the ability of Phenoptin to control blood phenylalanine levels in subjects who have hyperphenylalaninemia due to a primary BH4 deficiency and to evaluate the safety of Phenoptin in this population. Some subjects were receiving non-registered formulations of BH4 at enrollment and this treatment was suspended after Part 1 and within one day the subjects started Phenoptin at approximately the same dose.

Phenylketonuria (PKU) is a rare genetic condition. If not treated, PKU can cause severe mental retardation. Women with PKU are advised to eat a special diet when pregnant to prevent mental retardation in their children. This study will evaluate the effects of that diet on the children of mothers with PKU.
