26 Clinical Trials for Hypercholesterolemia
This is a pivotal phase III study designed to evaluate safety, tolerability, and efficacy of inclisiran in children (aged 6 to \<12 years) with heterozygous familial hypercholesterolemia (HeFH) and elevated low density lipoprotein cholesterol (LDLC).
This is a pivotal phase III study designed to evaluate safety, tolerability, and efficacy of inclisiran in children (aged 2 to \<12 years) with homozygous familial hypercholesterolemia (HoFH) and elevated low density lipoprotein cholesterol (LDLC).
This is an extension study to evaluate the longer-term safety and efficacy of enlicitide decanoate in adults with hypercholesterolemia who completed either study MK-0616-013 (NCT05952856), study MK-0616-017 (NCT05952869), or study MK-0616-018 (NCT06450366).
Multiple-dose study to measure pharmacokinetics, pharmacodynamics and safety of bempedoic acid in pediatric participants 6 to 17 years of age with HeFH.
The CASCADE-FH Registry is a national, multi-center initiative that will track the therapy, clinical outcomes, and patient-reported outcomes over time. The registry represents a collaboration between The Familial Hypercholesterolemia Foundation, the Duke Clinical Research Institute, lipid specialists, cardiologists, primary care providers, quality improvement personnel, and patients, all aiming to increase FH awareness, promote optimal disease management, and improve FH outcomes.
Very-low carbohydrate ketogenic diets can dramatically increase blood cholesterol levels, particularly in normal-weight people, for reasons that are not well understood. This study will enroll normal-weight adults, will identify "responders" who develop high cholesterol on a ketogenic diet, and will measure rates of production and removal of certain types of cholesterol-carrying particles called lipoproteins in responders. The results will clarify the mechanism by which a ketogenic diet can cause high cholesterol in certain susceptible people.
The goal of this implementation trial is to learn if providing education to doctors and patients who have had a heart event works to prevent future heart problems. The main questions it aims to answer are: 1. Does educating the doctors in a health system improve how often patients in the hospital for a heart event have their cholesterol checked? 2. Can a "care champion" who calls patients who have been discharged from the hospital after a heart event help patients to achieve their cholesterol goals? Researchers will compare the number of people who achieve their cholesterol goals with the help of the care champion to the number of people who did so without the intervention to see if the care champion works to help patients lower their cholesterol. Participants will: Complete two 15 minute surveys over the phone - 1 at enrollment and 1 at the end of the study 6 months later.
The purpose and objective of this study is to improve cholesterol treatment among blood donors with FH (Familial Hypercholesterolemia).
The overall goal of this study is to promote awareness of Familial Hypercholesterolemia (FH). The investigators aim to enroll patients with suspected FH into the study and will randomize them to receive usual care or motivational interview. Primary study outcomes include knowledge of FH, as well as clinical and patient-reported outcomes. This study aims to promote optimal disease management and improve outcomes of FH patients.
The Investigators will test the hypothesis that 2-HOBA will reduce modification of HDL and LDL and improve HDL function in humans with heterozygous FH. The Investigators plan to first study subjects with Familial Hypercholesterolemia (FH), treating them with 750 mg of 2-HOBA or placebo every 8 hours for 6 weeks.
This repository will establish for the first time a system to carefully assess and monitor over time the general health and the amount of cholesterol in the arteries of U.S. children and adults with homozygous familial hypercholesterolemia (hoFH). Patients with this very rare disorder have very high blood levels of cholesterol from birth due to the inheritance of an abnormal gene from each parent. As a result, if untreated, heart attacks and sudden death occur in childhood. Treatments such as LDL-apheresis and liver transplant will lower the cholesterol level, but the best treatment and the best way to monitor the effect of the treatment on the arteries are unknown. The collection of clinical data and blood for analysis of known and yet-to-be discovered markers and predictors of arterial disease will yield new information about the natural history of the disorder and response to treatment. The repository will greatly aid the development of specific protocols that seek to learn more about this disease and new therapies.
Statins are the most cost-effective medications to lower cholesterol and cardiovascular disease (CVD) risk. However, many patients at high-risk for CVD do not accept or adhere to statins. This gap in patient's use of statins limits the full impact of these effective medications resulting in higher cholesterol levels and CVD risk. The main barriers to using statins are patients' perceived lack of benefit, excess risk of statin toxicity as well as their misperceptions of their CVD risk. Statin pharmacogenomic testing - an application of precision medicine - is a readily available, feasible, and inexpensive intervention that addresses this barrier by using genetic testing to identify the nearly 1 out of 2 patients with enhanced benefit and/or reduced risk of statin toxicity or increased risk for CVD. By communicating statin pharmacogenomic test results to Veterans at high-risk for CVD not taking statin therapy, the investigators aim to improve patients' perceptions of their risk of CVD and statins and, in turn, their acceptance of and adherence to statins to reduce their cholesterol levels and CVD risk.
Homozygous familial hypercholesterolemia (HoFH), a rare inherited disorder caused by bi-allelic mutations in the LDL Receptor pathway, is characterized by extremely elevated levels of low-density lipoprotein cholesterol (LDL-C) from birth and premature atherosclerotic cardiovascular disease (ASCVD). Our current knowledge about HoFH is disjointed and largely stems from relatively small case series and expert opinion. HICC (Homozygous FH International Clinical Collaborators) is a global consortium of clinicians who are contributing de-identified data of patients diagnosed with HoFH with the goal to advance our understanding of this rare disease.
This study will evaluate people with dyslipidemias - disorders that affect the fat content in the blood. Fats, or lipids, such as cholesterol and triglycerides, are carried in the blood in particles called lipoproteins. These particles are involved in causing blood vessel diseases that can lead to conditions like atherosclerosis (hardening of the arteries) or heart attack. Participants will undergo accepted medical tests and procedures to evaluate their condition. Most of the test results are helpful in making a diagnosis and in guiding treatment. People with lipid disorders are eligible for this study. Representative types of patients include those with: * Plasma cholesterol levels greater than 200 mg/dl or less than 120 mg/dl * Plasma LDL-C levels greater than 130 mg/dl or less than 70 mg/dl * Plasma HDL-C levels greater than 70 mg/dl or less than 25 mg/dl * Unusual cholesterol deposits or xanthomas (nodules of lipid deposits on the skin) Children under 2 years of age are excluded from the study. Participants will undergo some or all of the following procedures: * Plasma evaluation. Apolipoproteins (plasma proteins involved in metabolism of cholesterol, triglycerides, phospholipids, and proteins in the blood) and enzymes involved in lipid metabolism are measured. * Fat biopsy. A small sample of fat tissue is collected for examination. For this test, an area on the buttock or abdominal wall is numbed. A needle is inserted into the fat, and a small amount of tissue is sucked out by a syringe. * Leukapheresis. White blood cells are collected to help diagnose the lipid disorder. For this test, blood is collected through a needle in an arm vein, similar to donating blood. The blood circulates through a machine that separates it into its components, and the white cells are removed. The rest of the blood is returned to the body, either through the same needle or through another needle in the other arm. * Skin biopsy. Skin cells are collected for study. The cells are grown in the laboratory and the amount of cholesterol that enters or leaves the cells is measured, providing information on abnormalities in cholesterol transport. For this test, an area of skin is numbed with an anesthetic and a small circular area is removed, using a skin punch instrument similar to a sharp cookie cutter. * Heparin infusion study. Heparin, a blood thinner, releases enzymes that break down fat in the blood. Lipase activity (breakdown of fats) in the blood is measured following the injection of heparin into a vein.
This is a study to evaluate the efficacy and safety of AZD0780 in adults with HeFH and elevated LDL-C, either with clinical ASCVD and LDL-C levels of 55 mg/dL or higher or without clinical ASCVD and LDL-C levels of 70 mg/dL or higher. AZD0780 is a small molecule that reduces the amount of LDL-C in the blood. Placebo will be used for comparison, and neither the participants nor the Investigators will know who is receiving the AZD0780 medication and who is receiving the placebo until the end of study. The total length of the study for an individual participant will be up to approximately 56 weeks, including a screening period of up to 14 days, treatment with AZD0780 or placebo for 52 weeks, and a safety follow-up period of 10 days.
The purpose of this open-label, single arm, multicenter extension study is to evaluate the long-term safety and tolerability of inclisiran in participants with HeFH or HoFH who have completed the ORION-16 or ORION-13 studies.
This global product exposure registry is a multicentre, long-term, prospective, observational cohort study (exposure registry), designed to evaluate the long term safety and effectiveness of lomitapide.
Emergency Medicine Cardiovascular Risk Assessment for Lipid Disorders (EMERALD) is a protocolized intervention based on American College of Cardiology/American Heart Association and US Preventive Services Task Force guidelines designed to initiate preventive cardiovascular care for emergency department patients being evaluated for acute coronary syndrome. The overarching goals of this proposal are to (1) determine the efficacy of EMERALD at lowering low-density lipoprotein cholesterol (LDL-C) and non high-density lipoprotein cholesterol (non-HDL-C) among at-risk Emergency Department (ED) patients who are not already receiving guideline-directed outpatient preventive care and (2) inform our understanding of patient adherence and determinants of implementation for ED-based cardiovascular disease prevention strategies.
Cardiovascular disease (CVD) is the leading cause of death in the US general population. Although CVD mortality rates declined for both Black and White populations during the past two decades, they are still higher in Black adults than White adults. There are also persistent disparities in CVD risk factors with higher prevalence of obesity, hypertension, and diabetes in Black compared to White populations. In addition, CVD and risk factors are more prevalent in the residents of Louisiana compared to the US general population. The Church-based Health Intervention to Eliminate Racial Inequalities in Cardiovascular Health (CHERISH) study will use a church-based community health worker (CHW)-led multifaceted intervention to address racial inequities in CVD risk factors in predominantly Black communities in New Orleans, Louisiana. The primary aim of the CHERISH study is to compare the impact of two implementation strategies - a CHW-led multifaceted strategy and a group-based education strategy - for delivering interventions recommended by the 2019 American College of Cardiology (ACC)/American Heart Association (AHA) Guideline on the Primary Prevention of Cardiovascular Disease on implementation and clinical effectiveness outcomes in predominantly Black church community members over 18 months.
This is a phase 3, randomized, placebo-controlled study of the efficacy and safety of enlicitide decanoate, an oral proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, in participants with high cardiovascular risk. The primary objective is to evaluate the efficacy of enlicitide decanoate compared with placebo in increasing the time to the first occurrence of major adverse cardiovascular events (MACE) including coronary heart disease (CHD) death, ischemic stroke, myocardial infarction (MI), acute limb ischemia or major amputation, or urgent arterial revascularization.
Socioeconomically disadvantaged populations with multiple chronic conditions have high rates of nonadherence to essential chronic disease medications after hospital discharge. Medication nonadherence after hospital discharge is significantly associated with increased mortality and higher rates of readmissions and costs among these patients. Major patient-reported barriers to essential medication use after hospital discharge among low-income individuals are related to social determinants of health (SDOH) and include: 1) financial barriers , 2) transportation barriers, and 3) system-level barriers. Although, medication therapy management services are important during care transitions, these services have not proven effective in improving medication adherence after hospital discharge, highlighting a critical need for innovative interventions. The Medication Affordability, Accessibility, and Availability in Care Transitions (Med AAAction) Study will test the effectiveness of a pharmacy-led care transitions intervention versus usual care through a pragmatic randomized controlled trial of 388 Medicaid and uninsured hospital in-patients with MCC from three large healthcare systems in Tennessee. The intervention will involve: 1) medications with zero copay, 2) bedside delivery then home delivery of medications, and 3) care coordination provided by certified pharmacy technicians/health coaches to assist with medication access, medication reconciliation, and rapid and ongoing primary care follow-up. We will examine the impact of the intervention during 12 months on 1) medication adherence (primary outcome) and 2) rapid primary care follow-up, 30-day readmissions, hospitalizations and emergency department visits, and costs. We will conduct key informant interviews to understand patient experience with the acre received during and after care transitions. By examining effectiveness of the intervention on outcomes including medication adherence, health care utilization, costs, and patient experience, this study will provide valuable results to health systems, payers, and policymakers to assist in future implementation and sustainability of the intervention for socioeconomically disadvantaged populations.
Cardiovascular disease (CVD) represents the leading cause of death worldwide. While medications, such as statins, significantly reduce atherosclerotic CVD (ASCVD) risk by lowering low density lipoprotein levels, they may also have pleiotropic effects on inflammation. The immunomodulatory effects of these medications are relevant to ASCVD risk reduction given that inflammation plays a central role in atherosclerotic plaque formation (atherogenesis) and influences the development of vulnerable plaque morphology. Patients on statins, however, may have residual inflammation contributing to incident ASCVD despite the potent LDL-lowering effects of statins. While new therapies, such as proprotein convertase subtilisin/kexin type 9 (PSCK9) inhibitors, further reduce incident ASCVD and drastically reduce LDL-C below that achieved by statin therapy alone, PCSK9 inhibitors may also have pleiotropic effects on inflammation. Thus, PCSK9 inhibitors may help reduce arterial inflammation to a level closer to that of patients without ASCVD. This study will apply a novel targeted molecular imaging approach, technetium 99m (99mTc)-tilmanocept SPECT/CT, to determine if residual macrophage-specific arterial inflammation is present with statin therapy and the immunomodulatory effects of PSCK9 inhibition. Given the continued high mortality and morbidity attributable to ASCVD, strong imperatives exist to better understand the immunomodulatory effects of lipid lowering therapies and residual inflammatory risk. This understanding, in turn, will inform the development of new ASCVD preventative and treatment strategies as well as elucidate other indications for established therapies.
An important aspect of successful genomic medicine implementation is developing effective approaches for screening at-risk family members after probands are identified, also known as cascade screening. Most cascade screening studies conducted to date have been conducted outside the US, and very few studies have used a rigorous approach involving a comparator group or randomized controlled design. A major question in the field is how to most effectively implement cascade screening, given commonly cited communication barriers, while respecting privacy among probands and family members. This study will conduct a randomized controlled trial to assess direct contact of relatives by study team members vs indirect, or proband-initiated, contact. We will assess efficacy of the cascade screening intervention, patient-centered outcomes regarding mental, physical, and psychosocial outcomes in probands and family members, and implementation evaluation outcomes. Individuals who are known to carry the KCNQ1 Met224Thr or APOB Arg3527Gln variant will be eligible to participate. After providing consent and being deemed eligible, individuals will be randomized in a 1:1 manner into the direct or indirect contact of family members arm of the study. The randomization will be stratified by variant to ensure equal representation of each variant in the study arms. Individuals in the indirect arm will be instructed to contact their first-degree family members about the opportunity to be screened. They will be provided with a disease-specific pamphlet and a family letter explaining the cascade screening. In the direct arm, probands will be advised that the study staff will be contacting their family members. They will be instructed to also contact their family members prior to the study team contacting them. Approximately two weeks after this meeting with the proband, the study staff will mail letters to eligible first-degree family members of the probands. If we do not hear back from individual family members, we will follow-up with another letter, telephone call, or home visit. The information contained in the letters will be the same information for both the direct and indirect arms of the study. All interested family members will receive pre-test counseling and free, in-home, saliva-based genetic testing, and post-test counseling.
The main aim of this study is to assess the effects of AZD0780 when added on top of ezetimibe or ezetimibe and rosuvastatin or ezetimibe and bempedoic acid.
This study looks at how lipoproteins, which are particles in the blood that transport cholesterol, influence heart and blood vessel health. Beyond just their levels, the way these particles function plays a key role in preventing or contributing to disease. In some conditions, like high cholesterol or diabetes, lipoproteins may not work properly, increasing the risk of clogged arteries and other complications. The investigators aim to study these changes in people with lipid disorders to better understand their impact on blood health and to find new ways to prevent and treat heart disease.
Cardiovascular disease is the leading cause of mortality after renal transplantation, accounting for more than 30% of deaths. Elevated lipid levels (hyperlipidemia) are a frequent finding following transplantation and the immunosuppressive medications play a central role in the development or worsening of hyperlipidemia. In the general population, the correlation between elevated serum cholesterol and increased risk of cardiovascular disease is well established and the reduction in serum LDL cholesterol has proved to significantly reduce both morbidity and mortality. Statin based drugs are the standard of care in the management of hyperlipidemia. Commonly used statin-based drugs include atorvastatin (Lipitor), fluvastatin (Lescol, Lescol XL), lovastatin (Mevacor, Altoprev), pravastatin (Pravachol), rosuvastatin (Crestor), simvastatin (Zocor), and pitavastatin (Livalo). These drugs have been proven to lower lipid levels as well as cardiovascular risk. However, statin-based drugs also cause a variety of side effects. While the most commonly encountered side effects are toxicity to the liver and muscles, a few others have also been known to cause increased excretion of protein in the urine and kidney failure. These side effects are also more common in a renal transplant recipient due to the simultaneous administration of drugs that prevent rejection. Therefore, there is an emergent need for newer drugs which are both efficient and safe especially in this population PCSK-9 inhibitors (Proprotein Convertase Subtilisin Kinase-9 inhibitors) are a new class of drugs that are highly efficient in lowering lipid levels in the general population. However, an exclusive trial involving kidney transplant recipients is yet to be done. Through this study, we would like to evaluate the safety and tolerability of Evolocumab (trade name: Repatha) which is a PCSK-9 inhibitor developed by Amgen, Inc in renal transplant recipients. The study would involve a total of 120 patients across 3 different hospitals in Boston, Massachusetts.
