Filter by:This study is a double-blinded randomized multicenter placebo controlled trial to determine the effect of adalimumab on vascular inflammation (ascending aorta and carotides) in patients with moderate to severe psoriasis.
In accordance with the recently revised FDA draft renal impairment guidance (March 2010) which advises the conduct of renal impairment study in drugs that are not predominately eliminated through the renal route, the proposed study will be conducted to formally assess the pharmacokinetics (PK) of darapladib in severely renally impaired subjects. In this is an open-label, non-randomized study eight subjects with severe renal impairment will be recruited along with 8 healthy control subjects matched to the severe renal impairment subjects based on gender, body mass index (plus or minus 20%) and age (plus or minus 10 years). All subjects will receive repeat oral doses of darapladib 160 milligram (mg) for 10 consecutive days. The pharmacokinetics of darapladib and its metabolites; and safety and tolerability will be evaluated. All the subjects will be admitted to the clinic on the evening of Day -1. Subjects may check out of the clinic on Day 2 after all assessments are complete, but must return to the clinic each day (Days 3-8) for dosing and assessments. Subjects will be admitted to the clinic again on the evening of Day 9. After the last dose of the study drug, there will be a follow-up period which will include 2 visits (Day 20-24 and Day 38-52). The total study duration for each subject including the screening, treatment and follow-up periods will be approximately 11 weeks.
The purpose of this study is to investigate the antiatherogenic effect of GSPE in clinical use
NG PROMUS: A Prospective, Multicenter Trial to Assess the NG PROMUS Everolimus-Eluting Platinum Chromium Coronary Stent System (NG PROMUS Stent System) for the Treatment of Atherosclerotic Lesion(s)
Study the mechanisms of atherosclerosis based on a comparative study of physical and chemical properties of lipid tissues at various localization with subsequent development of concept of treatment and prevention.
Major vascular surgery involves operations to repair swollen blood vessels, clear debris from blocked arteries or bypass blocked blood vessels. Patients with these problems are a high-risk surgical group as they have generalized blood vessel disease. These puts them at risk of major complications around the time of surgery such as heart attacks , strokes and death. The mortality following repair of a swollen main artery in the abdomen is about 1 in 20. This contrasts poorly with the 1 per 100 risk of death following a heart bypass. Simple and cost-effective methods are needed to reduce the risks of major vascular surgery. Remote ischaemic preconditioning (RIPC) may be such a technique. To induce RIPC, the blood supply to muscle in the patient's arm is interrupted for about 5 minutes. It is then restored for a further five minutes. This cycle is repeated three more times. The blood supply is interrupted simply by inflating a blood pressure cuff to maximum pressure. This repeated brief interruption of the muscular blood supply sends signals to critical organs such as the brain and heart, which are rendered temporarily resistant to damage from reduced blood supply. Several small randomized clinical trials in patients undergoing different types of major vascular surgery have demonstrated a potential benefit. This large, multi-centre trial aims to determine whether RIPC can reduce complications in routine practice.
The purpose of this study is to determine the prevalence of abdominal aortic aneurysm (AAA) and abdominal aortic atheromatosis (AA-At) using a hand-held ultrasound by a general practitioner in Primary Health Care.
Hardening of the arteries (atherosclerosis) is a common disorder that causes heart attacks and strokes. PET CT and contrast-enhanced MRI scans are two new ways of assessing atherosclerosis. The investigators propose to perform PET CT and MRI scans on patients with hardening of the neck arteries due to undergo surgery to remove the hardened areas. The investigators will then be able to compare the hot spots found on these scans with what the investigators can see in the removed specimens under the microscope in the laboratory. This will give investigators insight into the value of PET CT and MRI as tools for assessing atherosclerosis. It will also provide the investigators with new information relating to the underlying processes that give rise to atherosclerosis and will pave the way for the future development of new treatments.
Primary Objective: To compare the effect of alirocumab with placebo on the occurrence of cardiovascular (CV) events (composite endpoint of coronary heart disease (CHD) death, non-fatal myocardial infarction (MI), fatal and non-fatal ischemic stroke, unstable angina (UA) requiring hospitalization) in participants who experienced an acute coronary syndrome (ACS) event 4 to 52 weeks prior to randomization and were treated with evidence-based medical and dietary management of dyslipidemia. Secondary Objectives: - To evaluate the effect of alirocumab on secondary endpoints (any CHD event , major CHD event, any CV event, composite of all cause mortality/non-fatal MI/non-fatal ischemic stroke, CHD deaths, CV deaths, all cause mortality). - To evaluate the safety and tolerability of alirocumab. - To evaluate the effect of alirocumab on lipid parameters.
Patients suffering from symptomatic carotid artery stenosis, transient ischemic attacks (TIAs), amaurosis fugax or stroke receive either Revacept (single dose) plus antiplatelet monotherapy or monotherapy alone. Patients receive a single dose of trial medication by intravenous infusion for 20 minutes. Patients are followed up one and three days after treatment, at 3 months and by a telephone interview at 12 months.
