232 Clinical Trials for Various Conditions
The purpose of the proposed double-blind, randomized placebo-controlled trial is to understand how supplementation with fish oil \[docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)\] promote brain health against soccer heading. The study involves taking DHA+EPA or placebo, questionnaires, blood draws, brain imaging, tests to evaluate heart function, and soccer headings.
This phase II trial evaluates tamoxifen, with or without omega-3 fatty acids, for reducing risk of breast cancer among postmenopausal and overweight or obese women who are at increased risk of developing breast cancer. Tamoxifen is a selective estrogen receptor modulator. It works by blocking the effects of the hormone estrogen in the breast. Tamoxifen is approved by the Food and Drug Administration for prevention of breast cancer in women at increased risk. Omega-3 fatty acids have been shown to decrease the amount of fats made in the liver. Omega-3 fatty acids may work to prevent cancer in overweight or obese individuals. Tamoxifen with or without omega-3 fatty acids may be effective at reducing risk of breast cancer among women who are postmenopausal, overweight or obese, and at increased risk.
The goal of this intervention study is to determine if omega-3 fatty acid supplementation as compared to placebo improves performance in track and field athletes. The main questions it aims to answer are: 1. Can performance be improved 2. Can strength be enhanced 3. Will positive body composition changes occur (lean vs fat mass) 4. Will feelings of muscle soreness be diminished Participants will take either omega-3 fatty acid supplements or placebo and continue with their sport specific training regimen. Researchers will compare the supplement group to placebo group to determine if there are any significant differences.
This clinical trial will assess the whether fish oil supplementation can modulate brown fat activation, shivering, thermal comfort and skin blood flow during cold exposure.
Sickle cell disease (SCD) is associated with significant morbidity and mortality. Pain and many adverse outcomes occurring in sickle cell disease are inflammatory driven. Recent data has shown that gut dysbiosis is present in individuals with sickle cell disease. Gut dysbiosis has been linked to inflammation in certain diseases. Omega -3-fatty acids (fish oil) has been shown to improve pain outcomes in individuals with sickle cell disease, but its acceptance is variable. The aim of this study is to determine if a plant-based omega-3-fatty acids will be more acceptable and also improve outcomes in individuals with sickle cell disease
The purpose of the research is to evaluate if chicken that is fed a diet that contains omega-3 fatty acids (DHA/EPA), vitamin D (as 25(OH)D) or both nutrients provides additional health benefits by improving the status of omega-3 fatty acids and 25(OH)D in healthy adults who eat this bioenhanced chicken.
This phase Ib/II tests the safety, side effects, and best dose of icosapent ethyl in combination with dasatinib and whether they work to shrink tumors in patients with triple-negative inflammatory breast cancer that has spread to other places in the body (metastatic). Triple-negative inflammatory breast cancer is a type of inflammatory breast cancer in which the tumor cells do not have estrogen receptors, progesterone receptors, or large amounts of HER2/neu protein on their surface. Dasatinib is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply, which may help keep cancer cells from growing. Icosapent ethyl is an omega-3 fatty acid and in a class of medications called antilipemic or lipid-regulating agents. It may decrease the amount of triglycerides and other fats made in the liver. Preclinical studies have suggested that it may reduce the growth of triple negative inflammatory breast cancer cells. Combination therapy with dasatinib and icosapent ethyl may help shrink tumors in patients with triple-negative inflammatory breast cancer.
Diabetic peripheral neuropathy (DPN) is the most common chronic complication of diabetes, affecting about 50% of patients with diabetes and leading to severe morbidity, poor quality of life, high mortality, and high health care costs. Due to the complex structure and anatomy of the peripheral nervous system, DPN presents with a very broad spectrum of clinical symptoms and deficits, including severe pain, sensory deficits, foot ulcers and amputations. Presently there is no treatment for DPN and even with good blood glucose control DPN develops especially in patients with type 2 diabetes. There is a need to identify effective interventions for DPN. Preclinical studies have provided evidence that the combination of fish oil and salsalate is an effective treatment of DPN. The human subject study to be performed will examine the effect of fish oil with and without salsalate on the blood lipid profile and circulating metabolites of omega-3 polyunsaturated fatty acids (PUFA). Fish oil is an excellent source for the nutrition dependent omega-3 PUFA, primarily eicosapentaenoic acid (EPA; 20:5) and docosahexaenoic acid (DHA; 22:6). These fatty acids are the source of anti-inflammatory metabolites known as resolvin, neuroprotectin and maresin. Preclinical studies have also demonstrated that the metabolites of EPA and DHA are neuroprotective. Furthermore, when fish oil is combined with salsalate the production of these metabolites is increased in vivo. Thus, the investigators hypothesize that fish oil and salsalate will be an effective therapy of DPN. However, prior to doing a formal study of the effect of fish oil + salsalate on DPN there is a need to learn more about what concentration combination will provide the most efficacious effect on the omega-3 index (defined as the sum of EPA and DHA, as a percentage of total fatty acids in red blood cells) and that will safely increase the production of the anti-inflammatory metabolites. These studies will be performed at two sites the University of Iowa (Dr. Yorek) and University of Michigan (Dr. Pop-Busui) by treating human subjects with type 2 diabetes and DPN with either 2g or 4g of fish oil per day (capsules) for 4 months and then adding salsalate 1.5 g or 3g per day (tablets) to the fish oil treatments for an additional 2 months. At baseline and after treatment with fish oil alone and after treatment with the combination of fish oil and salsalate the omega-3 index and levels of circulating omega-3 PUFA metabolites will be determined as primary endpoints. Secondary endpoints will include determination of circulatory inflammatory markers and non-invasive measurements for DPN. The risks to subjects are minimal and are very reasonable in relation to the importance of the knowledge to be gained.
Majority of breast cancer survivors are overweight or obese at time of diagnosis, putting them at increased risk for insulin resistance and Type 2 Diabetes Mellitus (T2DM). Women with insulin resistance at time of breast cancer diagnosis often have larger tumors, later stages of cancer and worse prognosis. Additionally, chemotherapy often leads to increases in insulin resistance and cognitive impairment. Many cancer survivors experience memory and brain function decline following chemotherapy that can last for years, and insulin resistance may contribute to worse cognitive outcomes in cancer survivors. Omega-3 polyunsaturated fatty acids (PUFAs) are anti-inflammatory nutrients that may help reduce insulin resistance and negative cognitive outcomes from cancer treatments. The purpose of this observational study with cross-sectional design is to investigate the relationship of omega-3 PUFAs with insulin resistance and cognitive function in obese breast cancer survivors. Due to the global pandemic caused by the coronavirus disease of 2019 (COVID-19), this study will be conducted entirely remotely using electronic data collection and remote finger-stick blood sample collection. The study will aim to enroll 80 racially and ethnically diverse female breast cancer survivors (age 45-75) who are postmenopausal, and 1 to 4 years post breast cancer diagnosis. Participants will complete study questionnaires online, and some cognitive tests will be completed through zoom sessions with trained study personnel. Participants will be mailed kits with thorough instructions to complete fingerstick blood sample collections and mail them back to the research lab. Upon receipt of blood samples and completion of all study questionnaires, participation will be complete.
Elevated cholesterol, including triglyceride levels, can lead to the development of cardiovascular disease in adulthood. A diet that is rich in omega-3 fatty acids (O3FA) can improve triglyceride levels in a way that is safe and does not require medication. This is a single-center, prospective, unblinded, randomized-controlled dietary intervention study to assess the impact of an omega-3 fatty acid diet compared to a standard lifestyle intervention on serum triglyceride in patients with hypertriglyceridemia. The study consists of an 8-week dietary treatment period followed by an 8-week observation period.
The purpose of this trial is to determine the effect of maqui extract plus omega-3 fatty acids compared to a placebo for reducing inflammatory cytokine levels in older, obese adults.
Smoking is the most important modifiable risk factor for adverse pregnancy outcomes including preterm birth, neonatal death, and maternal complications. Rates of smoking cessation during pregnancy are low, particularly in underserved populations, and currently approved pharmacotherapies for smoking cessation either are considered unsafe in pregnancy or have uncertain effectiveness. Identifying safe and effective interventions, which might mitigate the adverse effects of smoking on maternal-fetal outcomes, is a major public health priority. We hypothesize that smoking-induced n-3 LCPUFA relative deficiencies may be an important mechanism contributing to tobacco-related adverse pregnancy outcomes and that n-3 LCPUFA supplementation specifically targeted to pregnant smokers may reduce these complications. Support for this hypothesis comes from a recent secondary analysis of the Omega-3 Fatty Acids Supplementation to Prevent Preterm Birth trial that found that only smokers taking n-3 LCPUFAs had a reduction in preterm labor risk as compared to non-smokers. While compelling, this study was a post hoc analysis that included only a small sample of smokers and did not collect data on smoking behaviors during follow up. Yet the ascertainment of longitudinal smoking behavior is critical, as some clinical studies have found that supplemental n-3 LCPUFAs might also reduce nicotine cravings, and lower daily cigarette use. Thus, smokers may doubly benefit from replenishing n-3 LCPUFAs via lower risk of preterm labor and/or increased smoking cessation. To address these knowledge gaps, we are proposing a multi-center, randomized, placebo-controlled, double-blinded study of n-3 LCPUFA supplementation in 400 pregnant smokers. We will collect detailed information on smoking behavior, validated biological markers of cigarette exposure (urinary cotinine, end-expiratory carbon monoxide) and biomarkers of n-3 LCPUFA status (red blood cell phospholipid membrane fatty acids). Our specific aims of this proposal are to 1) determine the effect of supplemental n-3 LCPUFAs on gestational age at delivery and preterm labor in pregnant smokers and 2) determine the effect of n-3 LCPUFA supplementation on tobacco use in pregnant smokers. We will recruit potential participants from eight obstetrics clinics across the Middle-Tennessee area. Our study could have a major translational impact on both adverse tobacco-related birth outcomes and smoking cessation efforts.
This is a Phase I/II single site, open label clinical trial. The purpose of the Phase I portion is to determine the safety, tolerability, and recommended Phase II dose of Eicosapentaenoic Acid (EPA) when given daily in combination with a Tyrosine Kinase Inhibitor (TKI) in subjects with Chronic Myeloid Leukemia (CML) in chronic stable phase. The recommended Phase II dose will be the maximum tolerated dose (MTD) of EPA as determined by the evaluation of dose-limiting toxicities (DLTs). The Phase II portion will subsequently examine the Anti-CML effects of EPA when administered with a TKI at the recommended Phase II dose. This efficacy objective will be done by evaluating BCR-ABL p210 quantitative PCR blood levels every 3 months to 1 year.
This is a pilot study aimed at assessing the effects of moderate dose omega-3-acid ethyl esters capsules (generic Lovaza) on molecular, and intestinal microbiota changes in participants at high risk for colorectal cancer. The study will be a single arm, open label study.
This is a randomized control trial testing the effect of walnut supplementation on prostate cancer progression in 50 men with biopsy confirmed prostate cancer and planning to undergo RP. Patients consented to the study will be randomly assigned to either continue their usual diets (control arm) or to the walnut arm for 4-10 weeks depending on the window between their consent date and the date for RP.
This study evaluates the efficacy of high-dose fish oil in decreasing rates of gastrointestinal bleeding in patients with continuous-flow left ventricular assist devices. Half of the patients without history of bleeding will receive fish oil while the other half will not. Half of the patients with history of bleeding will receive fish oil while the other half will not. Markers of angiogenesis and inflammation, as well as changes in the microbiome will be assessed in each group.
The aim of this feasibility study is to determine whether a nutritional intervention in children and their parents can improve their sleep quality and behavior. The study is a randomized, double-blind, placebo-controlled parallel trial of omega-3 supplementation to children and their mothers.
This is a prospective, double-blind, placebo-controlled, randomized clinical trial to assess the effects of daily 4-gram marine omega-3 polyunsaturated fatty acid (MO3PUFA), through treatment with AMR101 (VASCEPA, icosapent ethyl) on the tumor immune microenvironment and gut microbiome in patients who are diagnosed with colorectal cancer or with a colorectal mass or polyp suspected to be a cancer or advanced adenoma and will undergo surgical resection or interventional endoscopy at the Massachusetts General Hospital (MGH). It uses the novel "window-of-opportunity" clinical trial design to take advantage of the window of time between cancer/mass/polyp diagnosis and surgery to examine the effect of therapeutic agents on tumor pathologic and molecular features unperturbed by prior therapies.
The purpose of this study is to test the efficacy of an oral, nutrient intervention containing the bioactive components of fish oil to promote healing of chronic venous leg ulcers (CVLUs) by reducing the chronic inflammation at wound sites that prevents healing progression. If this systemic, nutrient intervention is found to alter the microenvironment of CVLUs, the science of wound healing and care of patients with CVLUs will be vastly improved.
This pilot study is an investigation of feasibility of moderate dose omega-3 fatty acid supplementation in pre-menopausal women at high risk for breast cancer who are considering future pregnancy.

The purpose of this study is to see if eating vitamin D, omega 3 and turmeric (curcumin) slows the growth of prostate cancer in men on active surveillance.
This protocol will determine the pK profile of two different omega-3 fatty acid supplements on plasma EPA and DHA levels.
The purpose of this study is to determine the safety of a new formulation of the omega-3 fatty acids Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) and to assess whether it decreases inflammation and inflammatory pain in children and young adults with Sickle Cell Disease.
This observational study recruits healthy individuals who have been routinely taking high amount (at least 3 g/wk) of dietary eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and those who don't, and examines the efficacy of dietary EPA and DHA in ameliorating the cardiopulmonary effects of exposure to ambient air pollution.
Employees working at DSM workplaces with an onsite Healthyroads Wellness® biometrics screening program are being offered an opportunity to have their blood fatty acids levels, especially omega-3 fatty acids \[omega-3 index\] measured at no charge. At some locations, participants were offered a single coupon on a 90 day supply of omega-3 capsules. Three months later, all employees at these locations are given a second opportunity to have their blood omega-3 levels \[eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)\] measured. The goals are to: 1) survey dietary EPA+DHA intake and omega-3 blood levels of study population, 2) determine if dietary EPA+DHA intake and omega-3 blood levels change after people have learned their omega-3 index, and 3) determine if differences in omega-3 index concentrations can be detected 3 months later between locations receiving information alone vs information+coupon.
This project aims to evaluate whether a dose-response relationship exists between dose of polyunsaturated fatty acids (PUFA), delivered as eicosapentaenoic acid (EPA), and change in markers of inflammation, and whether these effects differ from placebo. A key secondary aim is to evaluate the antidepressant effectiveness of EPA in overweight adult outpatients with current major depressive disorder (MDD). To address these aims, the project will use a four-arm, randomized, parallel-group, placebo-controlled design comparing placebo versus three doses of EPA (1 gm/day, 2 gm/day, or 4 gm/day) administered over 12 weeks. The study is to be conducted at two sites: Emory University School of Medicine, and Massachusetts General Hospital. Eligible participants will be between the ages of 18-80 who have current MDD, are overweight, and who demonstrate peripheral inflammation, defined as an high sensitivity C-reactive protein (hs-CRP) level ≥ 3 mg/L. The primary outcome will be change in plasma interleukin-6 (IL-6) levels and/or mitogen-stimulated peripheral blood mononuclear cells (PBMC) Tumor Necrosis Factor-alpha (TNF-α) expression levels in EPA- versus placebo-treated participants. The results of this investigation are intended to be used to design and power a larger definitive test of the efficacy and biological effects of EPA in patients with major depressive disorder.
Assess the impact of dietary omega 3 free fatty acids and/or letrozole on obese, postmenopausal breast cancer patients.
This study is a randomized, open-label, cross-over study in healthy subjects performed at a single study center. The study is divided into two parts, Part 1 and Part 2. The purpose of the study is to compare the pharmacokinetics (PK) of three different prototype capsule formulations (omega-3-carboxylic acids test formulations) with Epanova® capsules 1000 mg under fasted conditions in Part 1 and under fed conditions in Part 2. The results will be used as basis for choice of formulation for further pharmaceutical development.
This randomized pilot clinical trial studies omega-3 fatty acid in reducing cancer-related fatigue in breast cancer survivors. Supplementation with omega-3 fatty acid may help reduce cancer-related fatigue in breast cancer survivors.
This study is designed with the intention to further elucidate the effects of omega-3 fatty acids on intraocular pressure (IOP) and signs/symptoms of dry eye. Prior studies have shown statistically significant lowering of IOP with use of omega-3 fatty acids but have only been performed in animal models. This study will be the first to attempt replication in human models. A limited number of studies have shown an increase in tear production/volume as well as a decrease in the subjective symptoms of dry eye, but more studies are needed to better define these effects. Better understanding of the effects of this supplement on intraocular pressure and dry eye will contribute to the expanding knowledge about the pathophysiology of glaucoma/ocular hypertension and dry eye syndrome and potentially lead to further studies about new potential treatment options for these conditions.
