Filter by:The purpose of the ABSORB BTK Clinical Investigation is to evaluate the safety and efficacy of the Everolimus Eluting Bioresorbable Vascular Scaffold System (BVS) in subjects with critical limb ischemia (CLI) following percutaneous transluminal angioplasty (PTA) of the tibial arteries.
Investigate, under outpatient conditions, both the effect of 4 weeks of daily treatment with Prostaglandin E1 and that of 4 weeks of interval treatment (two infusions per week) on the pain-free walking distance in patients with Intermittent Claudication.
Peripheral arterial disease (PAD) is almost invariably associated with a generalized atherosclerotic involvement of the arterial tree and endothelial dysfunction. Previous short term studies showed improvement of vascular reactivity and walking capacity in PAD patients by measures aimed at restoring Nitric Oxide (NO) production. NO is also known to prevent the progression of atherosclerosis. We wished to assess whether the prolonged administration of a NO-donating agent (NCX 4016) improves the functional capacity of PAD patients and affects the progression of atherosclerosis as assessed by carotid intima-media thickness (IMT). Four hundred forty two patients with stable intermittent claudication were enrolled in a prospective, double blind, placebo-controlled study and randomized to either NCX 4016 800mg bid or its placebo for 6 months. The primary study outcome was the absolute claudication distance (ACD) on a constant treadmill test (10% incline, 3km/hr); main secondary end-point was the change of the mean far-wall right common carotid artery IMT.
Hypothesis #1. Supervised exercise rehabilitation will result in greater increases in exercise performance, peripheral vascular function, and health-related quality of life than compared to the attention-control group. Hypothesis #2. The change in peripheral vascular function will be predictive of improved exercise performance following the supervised exercise program.
Peripheral arterial disease (PAD) often causes exertion pain in the legs, intermittent claudication (CI) affecting> 10% of individuals> 65 years. A recent Swedish Health Technology Assessment Report identified only limited evidence for the effectiveness of invasive treatment for IC in patients already on exercise training. The prognosis for the extremity is usually benign and treatment therefore aims at improving quality of life. Invasive treatment can also cause serious complications. Coronary artery disease is common in IC patients increasing the risk with invasive treatment. In spite of these uncertain merits and potential risks, invasive procedures for IC are increasing and 37% of all invasive procedures for PAD in Sweden are performed for IC. The aim of this study is to evaluate the additional effects of modern invasive treatment in patients with intermittent claudication receiving modern best medical treatment (BMT). The primary hypothesis in the study is that invasive treatment in addition to BMT improves health related quality of life and walking performance compared to BMT only.
CLINICAL TRIAL PROTOCOL SUMMARY / SYNOPSIS Phase: IV TITLE OF STUDY Angioplasty or Bypass Surgery in Intermittent Claudication (ABC-Trial): a randomised controlled trial for patients with complex lesions of the superficial femoral artery CONDITION Peripheral arterial occlusive disease (PAOD) OBJECTIVE(S) The objective of this study is to evaluate the safety and efficacy of two therapeutic strategies (operative versus endovascular) in the treatment of patients with complex atherosclerotic lesions of the superficial femoral artery. INTERVENTIONS Intervention type I: Best endovascular treatment (stent-protected angioplasty). Intervention type II: Best surgical treatment (femoro-popliteal bypass above the knee with autologous vein (1° choice) or a prosthetic graft (if vein is not available). Duration of intervention per patient: Dependent on the method of treatment Follow-up per patient: 24 months OUTCOMES Primary efficacy endpoint: Two primary efficacy endpoints will be considered simultaneously in this trial: (A) Event-free survival (time-to-event endpoint): Proportion (over the course of time) of surviving patients who show a continuing clinical improvement of >= 1 class (Rutherford classification) without the need for repeated target lesion revascularization (TLR). (B) Proportion of surviving patients with clinical improvement of >= 1 class (Rutherford classification) at 24 months after primary intervention (regardless any performed re-intervention).
The primary objective is to assess safety and efficacy of two different doses of NV1FGF as compared to placebo. The secondary objective is to assess the pharmacokinetics of NV1FGF and FGF-1 protein.
The primary objective of this early-stage clinical study is to demonstrate an effect of single doses of CK-2017357 on measures of skeletal muscle function and fatigability in patients with peripheral artery disease and symptomatic claudication.
The purpose of this study is to evaluate the efficacy of a non-invasive peristaltic pulse pneumatic device (PCD) in the treatment of intermittent claudication in patients having documented peripheral arterial disease (PAD). The pneumatic device to be studied is FDA approved for the treatment of venous disease. While anecdotal evidence exists supporting a decrease in claudication symptoms, there are no previously published data on studies employing this compression device in the treatment of arterial disease. The investigators' primary hypothesis is that patients randomized to the intervention arm of the trial will experience an increase in mean walking ability as compared to the group receiving medical standard of care.
Metabolic syndrome, a group of cardiovascular risk factors related to insulin resistance, is a major determinant of cardiovascular mortality. Intermittent claudication is a symptom of an early stage of atherosclerosis. The aim of this study is to determine the prevalence of the metabolic syndrome in patients with intermittent claudication and its correlation with age, gender, localization of arterial obstruction and association with coronary artery disease.
