26 Clinical Trials for Various Conditions
This open-label field trial evaluates the effects of treatment with a multi-pathway dietary supplement (Stem Cell 100+) that has been commercially available for several years. The objective of the intervention trial is to determine if normal subjects over 35 years of age experience any observable health benefits from the dietary supplement as to their blood pressure, pulse rate, blood cholesterol, lung capacity, stress levels, or self reported changes in markers of overall health and life expectancy.
This study is being done with people with HIV infection who have low levels of HDL-C. HDL-C is a type of "good" cholesterol. People with low HDL-C have a higher risk of heart disease and may have problems with how their blood vessels relax. The endothelium is the inner lining of all blood vessels, such as arteries and veins. When the endothelium is not working properly, the blood vessels have trouble expanding properly, which contributes to the development of heart and blood vessel disease. The main purpose of this study is to see if taking either extended-release niacin or fenofibrate for 24 weeks will help blood vessels work better by improving endothelial function and increasing HDL-C. Niacin and fenofibrate are medications that raise HDL-C. This study will also help determine how safe extended-release niacin and fenofibrate are. The analysis is an as-treated analysis of participants who completed study treatment and had a week 24 BART scan. Safety analyses include all participants
The primary purpose of your participation in this study is to help answer the following research question(s) * Whether LY2484595 in combination with a statin drug (atorvastatin, simvastatin or rosuvastatin; currently used to treat abnormal fat or cholesterol in blood) improves the blood fat profile more than statins alone. * Whether LY2484595 alone improves blood fats profile compared to sugar pills. * Whether LY2484595 interferes with break down or functioning of statins. * Whether LY2484595 has any side effects that would not support testing it in future studies.
The purpose of this study is to investigate an oral formulation of RVX000222 for safety, pharmacokinetic and efficacy in healthy subjects.
The purpose of this study is to determine the effect of JTT-302 on the increase of High Density Lipoprotein-Cholesterol (HDL-C) levels when administered daily for four weeks in subjects with low HDL-C levels.
The purpose of this study is to evaluate the safety of JTT-302 when administered for eight or 12 weeks in subjects with low HDL-C levels and to determine the effect of JTT-302 on lipid parameters and CETP activity and mass.
We will test our primary hypothesis that combining niacin extended release (niacin-ER), at a daily dosage of up to 2.0 g with pioglitazone, at a daily dosage of 45 mg will result in a 12% greater increase in HDL-C when compared to niacin-ER monotherapy over 12 weeks in non-diabetic patients with the metabolic syndrome (see Table 1).
This was a double-blind randomized trial comparing 1200 mg per day of gemfibrozil with placebo in 2531 men with coronary heart disease, an HDL-C of 40mg/dl or less, an LDL-C of 140 mg/dl or less, and triglycerides of 300mg/dl or less. The primary outcome was nonfatal myocardial infarction(MI) or death from coronary causes. The median follow-up was 5.1 years. There was a risk reduction of 22% in the primary outcome (p=.0006) and 24% risk reduction in the combined endpoint of stroke, MI, and CHD death. The rate of events was reduced by raising HDL-C and lowering triglycerides without lowering LDL-C (N Engl J Med 1999;341:410-418).
The overall purpose of this project is to improve the clinical outcomes of veterans with ischemic heart disease (IHD) through implementation of evidence-based lipid management, with a particular focus on veterans whose primary lipid abnormality is a low level of HDL-cholesterol (the �good� cholesterol).
The Habitual Diet and Avocado Trial will evaluate the effects of providing one avocado per day for recommended consumption over a 6 month period in a cohort of approximately 1000 free-living participants with increased waist circumference in comparison with a control group that will maintain their habitual diets. Participants will be recruited and screened at 4 clinics in 4 locations: Pennsylvania State University; Loma Linda University; UCLA, and Tufts University (250 per site).
This is a pilot study to determine the association between Vitamin D deficiency in obese children and low high density lipoprotein (HDL) and dysfunctional HDL.
The purpose of this study is to assess the impact of 29 intravenous infusions of CER-001 vs. placebo, given at weekly (9 infusions) and biweekly (20 infusions) intervals on carotid vessel wall area as measured by 3TMRI, when administered to patients with familial primary hypoalphalipoproteinemia with proven CVD and appropriate background lipid-lowering therapy.
Approximately 24% of the US adult population meet criteria for metabolic syndrome (MetS), diagnosed by a combination of abdominal obesity, elevated blood pressure, high triglyceride and low HDL-cholesterol level, and pre-diabetes. MetS quintuples the risk of diabetes, and doubles the risk of cardiovascular disease (CVD), particularly heart failure. Lifestyle modification is the initial step of treatment, but few studies have demonstrated early and sustained efficacy in remission of MetS. Our preliminary studies of a lifestyle change program for patients with MetS included a 1-year of development of an intervention by an interdisciplinary team of experts in medicine and the behavioral sciences. The investigators then tested the efficacy of the intervention in a treatment-only, proof-of-concept study. The investigators achieved our goal of 50% MetS remission after 2 years, in a sample of 26 patients. This study is the second step of a research program testing an innovative bio-behavioral intervention aimed at remitting MetS through lifestyle intervention, by focusing on eating patterns, daily activity, and stress management. The overarching objective of this research program is to determine the efficacy of the ELM lifestyle intervention to achieve remission of MetS. This purpose of the current study is to prepare for a large, randomized, clinical trial by conducting a smaller clinical trial that examines the acceptability of the ELM intervention (ELM Group) as compared to two other intervention arms (ELM Classes, ELM Individual).
The purpose of this study is to investigate the use of radiolabeled particulate cholesterol administered intravenously in association with albumin, as a method to study reverse cholesterol transport (RCT) in humans by analyzing changes in the tracer activity in total plasma, lipoproteins and feces.
To determine whether the combination of ezetimibe and simvastatin improves biomarkers of atherothrombosis compared to simvastatin alone in patients with the metabolic syndrome.
The investigators propose to investigate if using a combination of medications that may improve cholesterol give additional benefit to that gained from the statin medication, Lipitor. It is recommended that patients who meet certain criteria for risk of heart disease take a statin medication to improve cholesterol and hopefully reduce risk of heart disease. The combination therapy will include Lipitor, Niaspan, and investigational medication (known as ABT335) in a class of drugs called fibrates. We are looking to see if and how these three medications together might improve risk factors for atherosclerosis and influence HDL cholesterol. The study will also look at the safety and any side effects that might be associated with this combination of medications.
The study evaluates high fiber diet intake in patients with hyperlipidemia.
Agents that increase HDL-C via reverse cholesterol transport could provide a new therapeutic option for the prevention of atherosclerotic cardiovascular disease. The investigators propose to investigate the effects of LY518674 on components that may likely affect atherogenesis in patients with the metabolic syndrome including HDL-C metabolism and reverse cholesterol transport pathways, the inflammatory response, and oxidative stress in human subjects. As an agonist of the nuclear peroxisome proliferator activated receptor (PPAR) alpha, LY518674 may affect the transcription of genes that encode various proteins involved in atherogenesis. This study will explore the consequences of altered transcription such as changes in messenger ribonucleic acid (mRNA) and protein levels as well as protein activity.
Lipoproteins are particles that carry fats such as cholesterol and triglycerides through the blood stream. These particles are involved in causing blood vessel disease that can lead to conditions like hardening of the arteries (atherosclerosis) or heart attacks (myocardial infarctions). This study is designed to look closely at the factors affecting lipoproteins. Researchers plan to study patients and normal volunteers by measuring lipoprotein levels in the blood. Patients and volunteers will be placed on a balanced diet during the study. In addition, researchers plan to measure levels of various hormone and enzymes in the blood. Patients and volunteers participating in the study may be asked to undergo more specific tests in order to collect more information about lipoprotein metabolism. This study may not provide direct benefits to patients and volunteers participating in it. However, information gathered from this study may help researchers develop better skills and techniques to diagnose and treat patients with diseases of lipoprotein metabolism.
Summary: Background: There is a lot of interest in the function and role of HDL to prevent and mitigate atherosclerosis in patients who are at or near LDLc targets. Statins have variable effects on HDLc which are accentuated in patients with a low baseline HDLc. Higher doses of statins are being used more commonly in practice based on newer outcomes studies which find greater benefits of the higher doses compared to lower or standard doses. This study is testing FDA approved dosages of two commonly used statin medications. Design: The study is designed to examine the effects of 80mg simvastatin and 80mg atorvastatin on HDLc concentrations. Serum will be saved for a hopeful collaborative effort with investigators at the U. of Washington who are able to do more advanced testing of HDL particle functionality. Based on the first 13 patients studied at Indiana University, the effects of these statins on HDLc concentrations vary greatly. It is unknown what impact these concentration changes have on the functionality of the particles however. A meta-analysis of 4 prospective trials published in JAMA in 2006 found that increasing HDLc with statins was independently associated with regression of atherosclerosis as measured by intravascular ultrasound. Patients: Patients with low HDLc will be the primary population recruited. Exclusion criteria include interacting medications, pregnancy, baseline hepatic disease or other illnesses which would put patients at increased risk of statin side effects.
In people with the metabolic syndrome, the investigators hypothesize that administration of a single 300 mg dose of a grape seed extract (GSE) will reduce insulin resistance (how well cells in the body can take up and use glucose), oxidative stress, and the amount of oxidized LDL in the blood during a 24 hour period. These measurements will be assessed at hourly intervals during the 24 hour study day protocol. Additionally, the investigators hypothesize that daily administration of 300 mg of GSE for 30 days will decrease baseline insulin resistance, oxidative stress, and the level of oxidized LDL in the blood.
This is a 2-part study. Part 1 is to determine the safety and tolerability in healthy participants of increasing daily doses of LY2484595 for 14 days to achieve a blood level of LY2484595 much higher than what is needed for therapy. The amount of study drug that reaches the bloodstream and the time it takes for the body to get rid of it will be determined. The effect of the study drug on factors in the blood related to cholesterol will be measured. Part 2 is to determine how ketoconazole affects how much of the study drug, LY2484595, gets into the bloodstream and how long it takes to get rid of it. Information about any side effects that may occur will also be collected.
The purpose of the study is to test whether increased saturated fat intake results in increased levels of larger LDL and HDL particles in individuals with LDL Pattern B.
This 4 arm study will evaluate the efficacy and safety of RO4607381 when co-administered with pravastatin in patients with low or relatively low HDL-C levels. Patients will be randomised to one of 4 groups to receive either RO4607381 300mg, 600mg or 900mg po daily, or placebo po daily, for 12 weeks.All patients will also receive pravastatin 40mg po daily for 12 weeks.The anticipated time on study treatment is 3 months and the target sample size is 100-500 individuals.
Coronary heart disease (CHD) is the single leading cause of death in the United States . Serum Cholesterol is known to have a direct impact on a number of human diseases through a variety of mechanisms. This is particularly true of cardiovascular disease. Measurement and manipulation of serum cholesterol has become a primary focus of primary care physicians and cardiologists when attempting to reduce risk of heart disease.
Approximately 1/4 of the US population has insulin resistance and the associated risk factors such as elevated lipid levels -triglycerides (type of fat from what we eat and what the liver produces and low HDL cholesterol which is the good cholesterol helping to protect against heart disease. Currently one known treatment for this a medication called fenofibrate, another medication that can improve insulin resistance is rosiglitazone, a third treatment known to improve insulin resistance an decrease triglycerides is weight loss. In this study insulin resistant individuals with elevated triglycerides and or a ratio of triglycerides to HDL cholesterol of 3:1 or greater will be randomized (selected by chance) to receive one of these treatments and results of insulin sensitivity and cardiac risk profiles will be compared at the end of the study.
