Active clinical trials for "Atherosclerosis"

This study aims to conduct a randomized, double blind, randomised controlled multicentre trial of sirolimus drug coated balloon versus standard percutaneous transluminal angioplasty for the treatment of superficial and popliteal arterial disease.

Intracranial atherosclerotic disease is the most common cause of ischemic stroke that is directly attributed to the progression or rupture of intracranial high-risk plaque in Asia. Many studies mainly from Euro-American population with a focus on extracranial carotid plaque have fully demonstrated the advantages of intensive statin therapy on stabilizing or reversing plaque burden, reversing plaque composition presenting that lipid-rich necrotic core (LRNC) is gradually replaced by fibrous tissue, and even reversing pattern of arterial remodeling to reduce the occurrence of cerebrovascular events. Yet, direct evidence of the effect of intensive statin therapy on intracranial atherosclerotic plaques is lacking and the effect of statin intensity and duration on intracranial plaque burden and composition is still unclear. High resolution magnetic resonance imaging (HRMRI) is a new and non-invasive technique that enable to assess the morphologic characteristics of vascular wall and plaque composition of intracranial artery. Based on above discussion, the investigators conduct this study to further determine the effect of intensive statin in ischemic stroke with intracranial atherosclerotic plaques.

This study aims to conduct a randomized, double blind, randomised controlled multicentre trial of sirolimus drug coated balloon versus standard percutaneous transluminal angioplasty for the treatment of below the knee arterial disease.

A prospective, single center, single arm non-randomized trial collecting safety and effectiveness data for the ABLUMINUS DES System to treat BTK lesions in subjects with CLI.

Endovascular revascularization and open bypass grafting above the knee show comparable results in primary 2-year patency (about 65%) in medium-length lesions - TASC II, C (Pereira et al, 2006). At the same time, a recent study, where the authors studied the effectiveness of stenting of long lesions (200 mm or more) of the chronic occlusions of the femoropopliteal segments (TASC II, D), showed unsatisfactory results (primary patency 45%) of the stented segment within 2 years (Lin et al, 2015). One of the possible solutions to the problem of breakage of stents in the femoral-popliteal position is a modified method of their manufacture by braiding from nitinol wire. Some studies with intervowen nitinol stents did show their resistance to breakage in this position. Moreover, the primary patency was > 70%. (Werner et al, 2014). These data suggest a better primary patency rate within 2 years with a longer lesion length (>200 mm). This is a prospective, randomized, open-label study. The main objective of the study is to compare the clinical efficacy and safety of two therapies for the treatment of prolonged atherosclerotic lesions of the arteries of the femoropopliteal segment above the knee, TASC II type D - femoropopliteal proximal shunting and recanalization with angioplasty and stenting using biomimetic interwoven nitinol stent in patients with symptomatic peripheral arterial disease at 24 months. Secondary objectives are to identify predictors of restenosis and occlusions of the operating segment and compare the quality of life of patients after the procedure. It is planned to recruit 110 patients (55 patients in each group). Observation period 2 years. Primary endpoint: -The effectiveness of the method of surgical treatment after 24 months (primary patency, primary-assisted patency, secondary patency). Secondary endpoints: Clinical efficacy of the method of surgical treatment after 24 months (MALE); Safety of the method of surgical treatment in the early postoperative period (hematoma of the surgical access area, peripheral neuropathy, purulent-infectious complications of the surgical access area) and after 24 months (MACE); Assessment of the quality of life in patients after surgical treatment at 6, 12, and 24 months (SF-36 questionnaire); Evaluation of prognostic factors for adverse outcomes after surgical treatment.

The purpose of the study is to evaluate the safety and feasibility of drug coated balloon in treatment of intracranial in-stent restenosis.

In a large number of patients who had a heart attack, multiple narrowings of the coronary arteries are identified. It is common practice to treat the narrowing that is the cause of the heart attack with a stent. It is not yet clearly known if the other narrowings in the other coronary arteries have to be treated immediately with a stent as well. "Bad" cholesterol (LDL-cholesterol) can speed up the formation of these coronary artery narrowings, and can thus make the risk of a second heart attack bigger. The investigators want to investigate if treating patients with the new cholesterol-lowering drug Evolocumab on top of the normal cholesterol lowering therapy (statins) ameliorates blood flow through coronary artery narrowings. Better blood flow through these narrowings could prevent the need for stenting or surgery in the future.

The purpose of the study is to evaluate the effect of olezarsen on percent change in fasting triglyceride (TG) levels compared to placebo in participants with hypertriglyceridemia and atherosclerotic cardiovascular disease, or with severe hypertriglyceridemia.

This is a randomized controlled study to assess the effect of atorvastatin and omega 3 combination therapy compared with atorvastatin and ezetimibe combination therapy in Korean T2DM patients with asymptomatic atherosclerosis.

VT-1001 is an open-label, phase 1b, single-ascending dose study that will evaluate the safety of VERVE-101 administered to patients with heterozygous familial hypercholesterolemia (HeFH), atherosclerotic cardiovascular disease (ASCVD), and uncontrolled hypercholesterolemia. VERVE-101 uses base-editing technology designed to disrupt the expression of the PCSK9 gene in the liver and lower circulating PCSK9 and LDL-C in patients with established ASCVD due to HeFH. This study is designed to determine the safety and pharmacodynamic profile of VERVE-101 in this patient population.
