Effectiveness

How Buphenyl Affects Patients

Phenylbutyric acid helps to reduce high levels of ammonia and glutamine in the blood of people with urea cycle disorders. It can also reduce inflammation in the digestive tract, regulate fluid movement between cells, and improve antioxidant levels. Additionally, studies suggest that phenylbutyric acid can stop or slow the growth of cancer cells. The way it works is by acting like a sponge to take up ammonia, helping proteins fold correctly, and by blocking certain enzymes from working.

How Buphenyl works in the body

Sodium phenylbutyrate is a drug that gets converted into phenylacetate when it enters the body. Phenylacetate is then combined with other molecules to create phenylacetylglutamine, which is eliminated from the body through the kidneys. This helps remove waste nitrogen from the body, in a similar way to the urea cycle. Each molecule of phenylacetylglutamine contains two moles of nitrogen.

When to interrupt dosage

The advocated dose of Buphenyl is contingent upon the diagnosed disorder, including Ornithine Transcarbamylase Deficiency, Citrullinemia and Enzymes. The amount of dosage is contingent upon the method of administration (e.g. Powder, for suspension - Oral or Oral) featured in the table underneath.

Buphenyl Toxicity & Overdose Risk

Taking too much sodium phenylbutyrate may be lethal in animals, but is unlikely for humans. High levels of its active metabolite, phenylacetate, have been known to cause nausea, headaches, fatigue, weakness, confusion, and disorientation. If an overdose occurs, medical attention should be sought and dialysis may be helpful. Animal studies have also shown that phenylacetate has the potential to be toxic to embryos and fetuses.

Behavioral Nudge for Genetic Predisposition

18+
All Sexes
Philadelphia, PA

Given the expansion of indications for genetic testing and our understanding of conditions for which the results change medical management, it is imperative to consider novel ways to deliver care beyond the traditional genetic counseling visit, which are both amenable to large-scale implementation and sustainable. The investigators propose an entirely new approach for the implementation of genomic medicine, supported by the leadership of Penn Medicine, investigating the use of non-geneticist clinician and patient nudges in the delivery of genomic medicine through a pragmatic randomized clinical trial, addressing NHGRI priorities. Our application is highly conceptually and technically innovative, building upon expertise and infrastructure already in place. Innovative qualities of our proposal include: 1) Cutting edge EHR infrastructure already built to support genomic medicine (e.g., partnering with multiple commercial genetic testing laboratories for direct test ordering and results reporting in the EHR); 2) Automated EHR-based direct ordering or referring by specialist clinicians (i.e., use of replicable modules that enable specialist clinicians to order genetic testing through Epic Smartsets, including all needed components, such as populated gene lists, smartphrases, genetic testing, informational websites and acknowledgement e-forms for patient signature); 3) EHR algorithms for accurate patient identification (i.e., electronic phenotype algorithms to identify eligible patients, none of which currently have phenotype algorithms present in PheKB; 4) Behavioral economics-informed implementation science methods: This trial will be the first to evaluate implementation strategies informed by behavioral economics, directed at clinicians and/or patients, for increasing the use of genetic testing; further it will be the first study in this area to test two forms of defaults as a potential local adaptation to facilitate implementation (ordering vs. referring); and 5) Dissemination: In addition to standard dissemination modalities,PheKB95, GitHub and Epic Community Library, the investigators propose to disseminate via AnVIL (NHGRI's Genomic Data Science Analysis, Visualization, and Informatics Lab-Space). Our results will represent an entirely new paradigm for the provision of genomic medicine for patients in whom the results of genetic testing change medical management.

ECUR-506 for Ornithine Transcarbamylase Deficiency

24 - 7
Male
Los Angeles, CA

Ornithine Transcarbamylase (OTC) deficiency, the most common urea cycle disorder, is an inherited metabolic disorder caused by a genetic defect in a liver enzyme responsible for detoxification of ammonia. Individuals with OTC deficiency can build-up excess levels of ammonia in their blood, potentially resulting in devastating consequences, including cumulative and irreversible neurological damage, coma and death. The severe form of the condition emerges shortly after birth and is more common in boys than girls. This is a Phase 1/2/3, open-label, multicenter, safety, efficacy, and dose finding study of ECUR-506 in male babies with neonatal onset OTC deficiency. The primary objective of this study is to evaluate the safety, tolerability, and efficacy of up to three dose levels of ECUR-506 following intravenous (IV) administration of a single dose.

PET Imaging for Alzheimer's Disease

18 - 99
All Sexes
Bethesda, MD

Background: About 5 million adults in the U.S. have Alzheimer s disease or another adult-onset neurodegenerative disorder. Many studies have found that inflammation in the brain contributes to these diseases. Researchers want to find a better way to measure this inflammation. Objective: To learn whether COX-1 and/or COX-2 is elevated in the brains of individuals with neurodegenerative brain disease compared to healthy volunteers. Eligibility: Adults age 18 years and older in good general health who have an adult-onset neurodegenerative dementia, such as AD, FTD, corticobasal syndrome, Huntington s disease, or MCI, ALS and healthy adult volunteers enrolled in protocols 01-M-0254 or 17-M-0181. Design: Participants will be screened with medical history, physical exam with vital signs, and lab tests. They will have a neuropsychological testing. Their heart function will be measured. Participants will have a magnetic resonance imaging (MRI) scan. The MRI scanner is a metal tube surrounded by a strong magnetic field. Participants will lie on a table that slides in and out of the tube. The machine makes noise. Participants will get earplugs. Participants will have 2 PET scans. They will be injected with the study drugs through an intravenous catheter placed in an arm vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. A plastic mask will be molded to their head to keep them from moving. A thin plastic tube will be put into an artery at the wrist or elbow crease area. This will be used to draw blood during the scan. Participants will have 2-5 study visits. Participation lasts 1 week to 4 months, depending on scheduling.
