6 Clinical Trials for Various Conditions
This clinical study was designed to assess the efficacy, safety, and tolerability of long-term dosing of inclisiran and evolocumab given as subcutaneous injections in participants with high cardiovascular risk and elevated low-density lipoprotein cholesterol (LDL-C).
This will be a randomized double blind placebo-controlled pilot study using a repeated measures design in which participants with acute ischemic stroke and intracranial atherosclerotic disease are randomized to either drug or placebo.
Stroke due to intracranial arterial atherosclerosis is a significant medical problem, carrying one of the highest rates of recurrent stroke despite best medical therapy, with annual recurrence rates as elevated as 25% in high risk groups. The goal of this investigation is to advance a promising surgical treatment for symptomatic atherosclerotic intracranial stenosis - encephaloduroarteriosynangiosis (EDAS). The investigation will test in a phase II futility trial the potential of EDAS for further development before proceeding with the design of a definitive clinical trial of EDAS Revascularization in patients with Symptomatic Intracranial Arterial Stenosis (ERSIAS). The investigation is a 4-year futility trial to test the hypothesis that EDAS revascularization combined with aggressive medical therapy warrants further evaluation in a subsequent pivotal trial as an alternative to aggressive medical management alone for preventing the primary endpoint of stroke or death in patients with symptomatic intracranial arterial stenosis (Specific Aim 1). During the investigation the time course of collateralogenesis and perfusion improvement following EDAS will also be evaluated (Specific Aim 2.
A retrospective review with four year followup on patients that had previously been enrolled in a study to evaluate blockages in the lower legs. The study looked at patients that had undergone a bypass of the leg from the groin to the knee area with an incision in each area using general anesthesia. These patients were compared to others who had undergone treatment with balloon dilatation and stents in the arteries in the thighs with only numbing medicine. The study was completed two years ago and was initially designed to look at outcomes at 24 months. Now the investigators are trying to go back and look at outcomes of these patients' treatment at 4 years by simply reviewing their records.
This study is a comparison of two different ways to treat blockage in the artery of the thigh. The first is an older way with incisions in the groin and just above the knee. A plastic tube is then inserted to make a bypass from the groin to the knee. The second treatment offered is through a needle hole in the groin. A thin plastic tube covering a metal stent is inserted into the artery and released to bypass the blockage from inside the artery. No incisions are needed. Patients are enrolled and then selected for one treatment method or another by chance. The patients will be followed for two years to see how the two different treatment methods work compared to each other.
The purpose of the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) is to compare the relatively new procedure of stent-assisted carotid angioplasty (CAS) to the traditional and accepted surgical approach of carotid endarterectomy (CEA) for the treatment of carotid artery stenosis to prevent recurrent strokes in those patients who have had a TIA (transient ischemic attack) or a mild stroke within the past 6 months (symptomatic) and in those patients who have not had any symptoms within the past 6 months (asymptomatic).
