The Merit WRAPSODY™ Endovascular Stent Graft for Treatment of Iliac Artery Occlusive Disease
Stenosis of ArteryPeripheral Arterial Disease2 moreThis is a prospective, single-center, non-randomized phase 2, first-in-iliac artery study, to evaluate the safety and effectiveness of the WRAPSODY Stent Graft for the treatment of peripheral arterial occlusive disease in symptomatic subjects with de novo or restenotic lesions in the common iliac artery (CIA) and/or external iliac artery (EIA), including lesions at the aortic bifurcation.
Pivotal Study of the Medtronic Axys EX Rotational Atherectomy System
Peripheral Arterial DiseaseThe primary objective is to demonstrate the safety and effectiveness of the Axys EX rotational atherectomy system in subjects with peripheral arterial disease who have de novo or non-stented restenotic obstructive lesions in the peripheral vasculature of the lower limbs.
Treatment of HDL to Reduce the Incidence of Vascular Events HPS2-THRIVE
Cardiovascular DiseasePeripheral Arterial Disease2 moreThe primary aim is to assess the effects of raising HDL cholesterol (the good type) with extended release niacin/laropiprant 2g (previously known as MK-0524A) versus matching placebo on the risk of heart attack or coronary death, stroke, or the need for arterial bypass procedures (revascularisation) in people with a history of circulatory problems. The secondary aim is to assess the effects of extended release niacin/laropiprant 2g daily on heart attack, coronary death, stroke, and revascularisation separately and to assess the effects on mortality both overall and in various categories of causes of death, and of the effects on major cardiovascular events in people with a history of different diseases at the beginning of the study.
A Study of GFH312 in Patients With Peripheral Artery Disease (PAD) and Intermittent Claudication...
Intermittent ClaudicationPeripheral Artery DiseaseGFH312 could be a novel therapeutic option in the acute/chronic inflammatory process of atherosclerosis and provides potential beneficial effects to microvasculature function for PAD patients with IC in addition to preventing ischemia-reperfusion injury. This phase II study is designed to explore the clinical safety and efficacy of GFH312 after multiple oral doses, to support further development in patients with PAD or other atherosclerotic diseases.
NAC Treatment and Outcomes in Patients With Advanced Atherosclerosis and DM
Atherosclerosis of ArteryPeripheral Artery Disease3 moreAtherosclerosis and diabetes are related to coronary artery disease and peripheral artery disease. The mechanisms are related to increased reactive oxygen species (ROS) formation and inflammatory cytokine secretion. However, simply using antioxidant or anti-inflammatory therapies has no optimal outcomes. On the other hand, N-acetylcysteine (NAC) which has both antioxidant and anti-inflammatory effects could effectively attenuate ROS production and reduce vascular inflammation. Hence, we will investigate the effect of NAC treatment on the outcomes in patients with advanced atherosclerotic heart diseases and patients with diabetes combined with significant peripheral artery disease.

Peripheral Artery DiseaseThe purpose of this study is to compare the effects of ticagrelor and clopidogrel in patients with Peripheral Artery Disease.
Optical Imaging Measurement of Intravascular Solution Efficacy Trial
Peripheral Artery DiseaseIodinated contrast is the current gold standard for infrainguinal angiography imaging in patients without renal insufficiency and has also been used with intravascular Optical Coherence Tomography (iOCT) to improve image quality in human coronary arteries as well as carotid arteries. The current debate in the literature for iOCT medium is between iodinated contrast and dextran and CO2 may offer a superior method of iOCT imaging during lower extremity occlusive disease interventions. The investigators hypothesize that the CO2 medium injection during iOCT data acquisition is feasible and will produce at least the same quality of imaging as that obtained with contrast or dextran without causing the problems of volume overload and renal toxicity seen with the two latter mediums. Primary Outcomes Measured Quality: Cumulative number of clear image frame (CIF) through the entire 54mm length segment. Quantitative: Calculations of the area and diameter of each segment will be measured to determine if index of refraction has any effect between the three mediums to be tested. The investigators expect to find little difference between all three iOCT mediums and hope to conclude that CO2 offers a superior side effect profile for iOCT imaging in the lower extremity arterial system.
Rivaroxaban for the Prevention of Major Cardiovascular Events in Coronary or Peripheral Artery Disease...
Prevention & ControlThe primary objectives of this study are: To determine whether rivaroxaban 2.5 mg twice daily (bid) + aspirin 100 mg once daily (od) compared with aspirin 100 mg od reduces the risk of a composite of myocardial infarction, stroke, or cardiovascular death in subjects with coronary artery disease (CAD) or peripheral artery disease (PAD); To determine whether rivaroxaban 5 mg bid compared with aspirin 100 mg od reduces the risk of a composite of myocardial infarction, stroke or cardiovascular death in subjects with CAD or PAD.
Effects of Paclitaxel on Intimal Hyperplasia
Peripheral Vascular DiseaseThis is a single, one time, limited dose infusion of Paclitaxel, that will potentially prevent recurrent stenosis secondary to intimal hyperplasia when compared to the control group at 10 months.
