Effectiveness

How Sodium Phenylbutyrate Affects Patients

Phenylbutyric acid is used to treat patients with urea cycle disorders, which involve high levels of ammonia and glutamine in the blood. It helps the body get rid of extra nitrogen waste. In the intestines, phenylbutyric acid has been shown to reduce inflammation and regulate fluid flow. It may also have anti-cancer properties and could be used to prevent or treat certain types of cancer. It may work by acting as an ammonia scavenger, chemical chaperone, and histone deacetylase inhibitor.

How Sodium Phenylbutyrate works in the body

Sodium phenylbutyrate is a form of phenylbutyric acid used as a drug in the body. It is quickly converted into phenylacetate, which then combines with glutamine to form phenylacetylglutamine. This compound is then passed by the kidneys and helps remove nitrogen from the body in a similar way to urea.

Patient Q&A Section about sodium phenylbutyrate

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is sodium phenylbutyrate used for?

"Sodium phenylbutyrate is a drug used to treat urea cycle disorders, which are conditions that prevent the body from removing ammonia (nitrogen) from the blood. Ammonia is produced when protein is broken down in the body."

Answered by AI

Is sodium phenylbutyrate FDA approved?

"After nearly two years of discussions, the US Food and Drug Administration has approved Ucyclyd Pharma's orphan drug, Buphenyl (sodium phenylbutyrate), to treat urea cycle disorders. The drug allows patients to excrete waste nitrogen which would otherwise accumulate as ammonia and may cause brain damage and death."

Answered by AI

Is sodium phenylbutyrate over the counter?

"Ammonia is a substance that is produced when protein breaks down in the body. If the body is unable to get rid of the ammonia, it can cause serious problems. sodium phenylbutyrate helps to reduce the amount of ammonia in the blood. This drug is only available with a prescription from a doctor."

Answered by AI

Is sodium phenylbutyrate the same as sodium butyrate?

"PBA is a derivative of the short-chain fatty acid butyrate and is approved for treatment of urea cycle disorders and progressive familial intrahepatic cholestasis type 2."

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.
