The objective of this study is to utilize information on associations between genetic predisposition pertaining to multiple single nucleotide polymorphisms (SNPs) and the degree of responsiveness of low-density lipoprotein cholesterol (LDL-C) lowering to plant sterols (PS). The predictive potential of SNPs associated with PS responsiveness will be evaluated using a randomized human intervention trial examining responsiveness of lowering blood LDL-C levels to PS intervention.
This is a Phase I, first-in-human (FIH) study to assess the safety, tolerability, pharmacokinetics (PK) and Pharmacodynamics (PD) of AZD4831 after single and multiple ascending doses in healthy male subjects
B-HIVE is a Phase 3, double blind, placebo-controlled, randomized, parallel group study, designed to compare the efficacy and safety of bococizumab 150 mg subcutaneously every 2 weeks to bococizumab placebo subcutaneously every 2 weeks for LDL-C lowering in HIV-infected subjects.
Anemia which is a decreased blood count or lower than normal hemoglobin (hgb), is a major health problem for patients having heart surgery. Hemoglobin is the part of our blood that carries oxygen from the lungs to the rest of the body. Anemia that is present before surgery, called preoperative anemia, is a risk factor for an increased chance of morbidity (illness) and/or mortality (death) after heart surgery. It is also an important indicator of blood transfusion necessity. Recent clinical research investigations done to study preoperative anemia suggest a blood transfusion can damage the immune system (the system that protects us from disease) which can lead to infection, organ dysfunction (especially of the heart, kidney, brain), prolonged hospital stays, as well as increased supplies, resources and cost in surgical patients. Comprehensive anemia management can reduce or eliminate the need for blood transfusions and provide better outcomes after surgery. Therefore, controlling anemia before surgery is extremely important, and could be a lifesaving measure. This pilot, feasibility study is being done for several reasons. First of all, it will test the the safety and effectiveness of using a short-course of two medications, erythropoietin (EPO) and Feraheme (iron given intravenously [IV]), to increase hemoglobin levels in order to improve preoperative anemia, reduce transfusions and lower postoperative complications in anemic patients undergoing heart surgery. Secondly, findings will be used to design a large randomized controlled trial (RCT). The RCT will establish a protocol to actively manage anemia before surgery, thus reducing transfusions during surgery and improving recovery afterwards. It will also help identify valuable information regarding what needs to be done for timely completion of the planned RCT. EPO is a medication approved by the Food and Drug Administration (FDA) used to treat anemia in patients with certain conditions in order to reduce blood transfusions. And although approved for use during surgery, it has not been FDA approved for use in cardiac (heart) or vascular (blood vessels, including veins and arteries) surgery. Common side effects include nausea, vomiting, itching, headache, injection site pain, chills, deep vein thrombosis (blood clot), cough, and changes in blood pressure (BP). Feraheme is an iron replacement product approved for the treatment of low iron anemia in adult patients. It may cause serious allergic reactions, including anaphylaxis (severe, whole body allergic reaction), as well as low BP and excessive iron storage. Patients meeting all eligibility requirements that consent to participate will be randomized into the study. Randomization is being placed by chance (like a flip of a coin) into one of two study groups, the treatment group or the control group. There is an equal chance of being placed into either group, which will be done by a computer. 1. The Treatment Group will receive a 300 unit (U) per kilogram (kg) injection of EPO and a 510 milligram (mg) IV infusion of Feraheme 7-28 days before the day of surgery. And again 1-7 days before the day of surgery, a second dose of both of these medications will be given. The third dose, of EPO only, will be administered 2 days after surgery. Before initiating a dose or giving a subsequent dose, laboratory parameters will be measured to assess the hemoglobin level and response to the medication. If blood values increase too rapidly or are too high, the meds will not be started or, if already dosed, they will not be given again. 2. The Control Group will receive no preoperative intervention for anemia unless lab results show iron deficiency anemia. The control group will be screened for the presence of iron deficiency anemia by evaluating blood laboratory values drawn during the baseline or preoperative visit. If lab results indicate iron deficiency anemia, over-the-counter oral iron will be recommended, to take until the day of surgery. In doing so, patients may benefit by potentially reducing the need for blood transfusions. Data will be collected from all participants from the preoperative visits throughout the admission, including lab results, medications, vital signs, information about the procedure, transfusions, and any problems or adverse events.
This study was a prospective, randomized trial designed to investigate the efficacy of moderate lifestyle modification for improving the clinical status of patients with coronary artery disease or patients with risk factors that promote coronary artery disease.
This study evaluates the PCSK9 inhibitor, Bococizumab (PF-04950615;RN316), compared to placebo, in reducing the occurrrence of major cardiovascular events, including cardiovascular death, myocardial infarction, stroke, and unstable angina requiring urgent revascularization in high risk subjects who are receiving background lipid lowering therapy and have cholesterol laboratory values of LDL-C >/= 100 mg/dL (2.6 mmol/L) or non-HDL-C >/=130 mg/dL (3.4 mmol/L).

The purpose of this study is to establish a registry that uses observational study methods to collect uniform data (clinical, lifestyle and other) to evaluate specific outcomes and to enable research on patients at risk for cardiovascular disease (CVD). This is a descriptive, observational registry study. All data for participants in the WRNMMC Integrative Cardiac Health Project (ICHP) Cardiovascular Health Program (CHP) will be entered into a single, secure information management system (IMS) for subjects at risk for CVD. At periodical intervals, the IMS will be queried to define the effect of an integrative therapeutic lifestyle change (TLC) program on CVD risk over time. This protocol outlines collection, storage, and handling of data, describes specific data elements and lays the foundation for future research questions.
Brown adipose (fat) tissue (BAT) is a type of fat tissue found in certain small rodents and human babies that is capable of extremely high rates of energy burning. We now know that in adult humans it is present and also able to burn energy. In addition to increased energy expenditure during cold exposure, energy burning is also increased after consuming a meal. Animal studies have shown that part of this additional energy consumption is contributed by BAT. In the present study we will aim to examine whether BAT activity is increased after a meal.
The aim of this study is to evaluate if synchronizing when patients with diabetes and/or coronary artery disease fill their prescriptions improves long-term adherence to these medications.
