153 Clinical Trials for Various Conditions
The goal of this clinical trial is to learn if drug RDX-002 works to treat high levels of fat (known as triglycerides, or TGs) in the blood in adults. It will also learn about the safety of drug RDX-002. The main question it aims to answer is if treatment with RDX-002 will lower triglycerides after a high-fat meal in patients who have recently stopped treatment with semaglutide or tirzepatide for obesity. The trial will also examine the effect of RDX-002 on body weight and fasting levels of cholesterol. Researchers will compare RDX-002 to a placebo (a look-alike substance that contains no drug) to see if RDX-002 works to reduce triglycerides. Participants will: Take drug RDX-002 or a placebo every day for 12 weeks Visit the clinic once every 4 weeks for checkups and tests
This is a prospective, observational study which examines the association between maternal triglycerides in the antepartum period and fetal overgrowth in pregnancies complicated by gestational diabetes. Mothers are asked to provide 2 blood samples, undergo fingerstick blood measurements, and to have their newborns measured for body fat composition in the first 6 months of life.
This study plans to learn more about how triglyceride levels in pregnancy affect newborn fat mass. Obesity in pregnancy, in the absence of gestational diabetes, is now the most common cause of large-for-gestational-age infants and increased newborn fat mass. Previous data supports the idea that maternal triglycerides, not glucose, are the strongest predictor of both total newborn fat mass and liver fat. In this study, mothers will monitor triglyceride and glucose levels at specific points in pregnancy using point-of-care meters at home. Two weeks after birth, infants will have total fat measured by air-displacement plethysmography (PEAPOD) and liver fat measures by Magnetic Resonance Spectroscopy (MRS). The central hypothesis is that in obesity, fasting triglycerides and postprandial triglycerides will predict newborn fat mass in a free-living environment.
This study plans to learn more about how an omega-3 fatty acid supplement effects triglyceride levels in pregnancy. Triglycerides are a type of fat found in your blood. Your body converts extra calories into triglycerides to be stored and used later for energy. It is normal for triglyceride levels to go up during pregnancy however some women have levels that are \~30-40% higher than normal when they reach their third trimester of pregnancy. Having high triglycerides in pregnancy may be related to an increased chance of having a baby that is large for their age. The goal of this study is to determine if taking an omega-3 fatty acid supplement can slow the rise in triglyceride levels later in pregnancy.
The primary objective of this study is to determine the efficacy of CaPre 4 g daily, compared to placebo, in lowering fasting triglyceride (TG) levels in patients with fasting TG levels ≥500 mg/dL and ≤1500 mg/dL (≥5.7 mmol/L and ≤17.0 mmol/L) after 12 weeks of treatment. Approximately 615 subjects will be screened to obtain 245 randomized subjects following a 2.5:1 treatment allocation ratio (CaPre: placebo).
The primary objective of this study is to determine the efficacy of CaPre 4 g daily, compared to placebo, in lowering fasting TG levels in subjects with fasting TG levels ≥500 mg/dL and ≤1500 mg/dL (≥5.7 mmol/L and ≤17.0 mmol/L) after 12 weeks of treatment.

The primary objective is to determine the efficacy of AMR101 (ethyl icosapentate) compared to placebo in lowering high fasting triglyceride levels in patients with high risk for cardiovascular disease and fasting triglyceride levels ≥ 200 and \< 500 mg/dL.
Lovaza is a special fish oil concentrate, that prescribed at 4 g a day to reduce certain fat (triglycerides) levels in blood.Our goal is to study how Lovaza at doses of 4, 8, and 12 grams per day will reduce fats in the blood of the patients with very high level of triglycerides. Our hypothesis is that patients with very high triglycerides will respond more with higher doses of Lovaza (8 g per day and then 12 g per day).
The overall hypothesis of these studies is that circulating triglycerides, coming primarily from fat in the diet, are an important source of free fatty acids. Free fatty acids are the major fat fuel in the body, and when they are elevated in the blood they are thought to raise the risk of cardiovascular disease by causing insulin resistance (in some cases leading to diabetes), raising blood pressure, and other effects. The investigator will use sophisticated methods for tracing triglycerides and free fatty acids in the blood. These methods involve the administration of low doses of radioactive and stable isotopes of naturally occurring fats. The studies will determine the contribution of triglycerides to free fatty acids in normal people and also in people with diabetes.
The purpose of this small, short pilot study is to determine the feasibility (e.g., recruitment, dose acceptance, retention) of a future longer trial comparing the effects of two types of omega-3 fats from fish oil on plasma triglycerides. The two types of fish oil are composed of (1) omega-3 fatty acids in triglyceride form; and (2) as esterified free fatty acids (i.e. ethyl esters). Although these two types of fish oil supplements are available to the public, it remains unclear whether they are equally effective in lowering plasma triglycerides.
The investigators will conduct a randomized clinical trial to evaluate the efficacy of Lovaza (formerly known as Omacor) in reducing triglyceride levels in youth ages 10-19 years old whose baseline triglycerides range from 150 mg/dl to 1000 mg/dl. Seventy subjects will be recruited at baseline and randomized to the treatment condition, Lovaza 4 grams/day for 6 months or the control condition, a corn oil placebo, 4 tablets a day for 6 months. Participants in both the treatment and control groups will receive the standard of care, which is dietary advice to follow a low, refined carbohydrate and low saturated fat diet that emphasizes increasing intake of fruits and vegetables and eating 2 servings per week of fishes rich in omega-3 fatty acids, consistent with the American Heart Association recommendations. The primary outcome will be change in fasting triglycerides from baseline to 3 months. The investigators hypothesize that patients who receive LOVAZA will have significantly greater reductions in plasma triglyceride levels when compared to patients on placebo at 3 months.
The purpose of this study is to evaluate the cardiovascular and lipid effects of two doses of an omega-3 fatty acid concentrate in a group of people who normally are not treated for high lipids.
This study will explore the ability of an algae (ocean plant) omega-3 fat supplement (DHA) to reduce triglyceride levels in patients currently being treated with statin therapy (Zocor or simvastatin, Lipitor or atorvastatin, Pravachol or pravastatin, Crestor or rosuvastatin, etc.) for coronary artery disease(CAD)or risk equivalents (any of the following: heart attack, post angioplasty or stent, post coronary bypass surgery, angina, vascular disease, stroke or diabetes). The rationale for the study is based around the finding that patients with CAD have an approximately 20 % reduction in the risk of sudden death when treated with fish oil (DHA is one of the ingredients in fish oil). In studies of statin-based therapies, it has been observed that statins reduce the risk of coronary events 20-45%. There has not yet been research trials exploring the combination of the two ingredients (i.e., DHA plus statin) in patient treatment either to reduce recurrent cardiac events or to address another reported finding of fish oils to lower triglyceride levels (triglyceride is a form of "blood fat"). This research project will be a pilot project to assess the safety and effectiveness of DHA "add-on" therapy in patients currently being treated with statins for CAD. The study hypothesis is to test the effectiveness of DHA as compared to placebo to lower triglyceride levels in the blood. This is a double-blinded randomized clinical trial.
The purpose of this study is to evaluate the efficacy and safety of omega-3-fatty acids in HIV-infected patients with hypertriglyceridemia. In addition, we, the researchers, will evaluate the effect of omega-3 fatty acid administration of markers of bone turnover and inflammation.
The purpose of this study is to examine the role of glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) in triglyceride metabolism.
Background: People with familial partial lipodystrophy (FPLD) do not store fat in the body normally. This can lead to serious illnesses such as diabetes and heart disease. To learn more about FPLD, researchers want to compare the fat tissue in people with this disease to the fat tissue of healthy people. Objective: To collect and analyze samples of fat tissue in people with and without FPLD. Eligibility: People aged 18 to 65 years with FPLD. Healthy adults are also needed. Design: Participants will be screened. They will have a physical exam. The size and shape of their body will be measured. They will have an imaging scan to measure their bones, muscle, and fat. Participants will be given heavy water to drink at home. The water contains a tracer to help measure the fat in their blood. They will drink 1 vial 3 times a day. After drinking the water for 9 days, participants will come to the clinic for a 3-day stay. They will eat only foods provided by the hospital; the foods will contain tracers. A needle will be inserted into a vein in the arm; participants will receive infusions of other tracers through this needle into their blood; this needle will also be used to draw blood samples for testing. On their third day in the clinic, participants will have biopsies: Small samples of fat will be removed from under the skin on the belly and thigh. Participants may return for a follow-up visit 8 days after leaving the clinic. Blood draws and fat tissue biopsies will be repeated.
This Phase 1b Study RDX-002-22-09 has been planned to evaluate the effect of RDX-002 on postprandial triglycerides and ApoB48 levels in normal healthy subjects treated with the atypical antipsychotic drug, olanzapine.
The 'Western diet' characterized by high fat feeding (HFF) is a risk factor for Alzheimer's disease (AD); however, little is known about mechanisms. Paradoxically, individuals who carry the AD risk gene APOE E4 cognitively improve after HFF and show different metabolic responses to fat intake. These responses include a more pronounced drop in systolic blood pressure and a decrease in cerebrospinal fluid glucose and lactate levels. This proposal will further examine the brain metabolic response to HFF using non-invasive imaging. Cerebral blood flow (CBF) as assessed by functional MRI is increasingly utilized to investigate brain function, given that CBF is tightly coupled to brain metabolism. Acute changes in CBF have been described in response to carbohydrate ingestion in regions important for learning and memory; however, no one has yet assessed CBF response to lipid. Here investigators propose to characterize CBF changes to a high fat drink in older adults. This study will include a time course assessment as well as analyses of global and regional change in CBF. These data would serve as feasibility pilot data for an R01 application which would include cognitive and peripheral metabolic data. These types of studies will provide a clearer picture of acute brain metabolic response to HFF in older adults, including the effects of APOE.
High fat feeding (HFF) increases the risk of Alzheimer's disease (AD) but individuals who carry the AD risk gene E4 paradoxically improve after acute HFF. The investigators propose to further study this phenomenon with a clinical study to assess cerebral blood flow which can be measured by a technique called arterial spin labeling (ASL) on an MRI and is tightly related to brain metabolism.
Background: The ketogenic diet uses fats as a person's major energy source rather than carbohydrates. There is increasing interest in using this diet to treat neurodegenerative disorders like Parkinson's disease. Researchers want to learn more about the ketogenic diet before recommending this diet in clinical practice. Objective: To study the effects of a ketogenic diet for someone with PD. Eligibility: People over age 50 with mild to moderate PD. Design: Participants will be screened with surveys and a 10-foot walking test. They will have a medical history, physical exam, and blood test. Participants will be contacted twice in a 1-week period to discuss what they ate over the last 24 hours. They will log data about their daily exercise and activities using an online fitness tracking app. Participants will stay at NIH Clinical Center for 1 week. They will be put into 1 of 2 groups. One group will follow a ketogenic diet and take MCT oil. The other group will follow a low-fat diet. Their body measurements will be taken. They will meet with a physical therapist and nutritionist. Participants will have daily respiratory and glucose monitoring. They will have cognitive tests and complete surveys. They will have walking, motor function, and reaction time/finger tapping tests. They will have heart and nerve function tests. They will have electrocardiograms and electroencephalograms. Blood will be taken twice daily. Participants will follow the ketogenic diet at home for 2 weeks. They will log their activities using the fitness tracking app. Then they will have a follow-up visit at NIH. Participation in the trial will last for 4 weeks.
This study evaluates whether adding a dietary supplement similar to coconut oil (MCT oil) to feedings in premature infants will reduce the amount of yeast (Candida) detectable in their stool. Infants who have Candida in their stool are eligible to participate. Half of the enrolled infants will have additional MCT oil added to their feedings and half will not.
The purpose of this study is to investigate the effect of 4 days of sitting and moderate exercise on plasma triglyceride elevation after a meal.
