Filter by:This study is done to see if semaglutide has an effect on walking ability compared with placebo (dummy medicine) in people with peripheral arterial disease (PAD) and type 2 diabetes. Participants will either get semaglutide or placebo ("dummy") medicine - which treatment participants get is decided by chance. Semaglutide is a medicine for type 2 diabetes that can be prescribed by doctors in some countries. Participants will get the study medicine (semaglutide or placebo) in a pre-filled pen for injection. Participants must inject it once a week into the stomach area, thigh, or upper arm, at any time of the day. The study will last for about 59 weeks. Participants will have 8 clinic visits and 1 phone call with the study doctor. At some clinic visits, participants will have blood tests. At some visits participants will also do a treadmill test to measure how far they can walk. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period.
The SAFE-PAD Study aims to evaluate the long-term safety of paclitaxel-coated devices compared with non-paclitaxel-coated devices for femoropopliteal artery revascularization among a broad, real-world population of patients with peripheral artery disease. This multi-year analysis aims to create an ongoing mechanism to evaluate the safety of paclitaxel-coated devices in real world practice. The null hypothesis is that the paclitaxel-coated devices are associated with an increase in mortality relative to the non-drug-coated devices beyond an acceptable magnitude (i.e. the non-inferiority margin), and the alternative hypothesis is that paclitaxel-coated devices are not associated with an increase in mortality relative to the non-drug-coated devices beyond the non-inferiority margin.
Exercise training improves walking capacity and regional perfusion in patients with Intermittent Claudication (IC). Endothelial Progenitor Cells (EPCs) and Endothelial Microparticles (EMPs) could play an important role in this process, promoting the healing of the diseased endothelium. The investigators are going to measure EPCs and EMPs in a group of patients with IC and in a control group of healthy individuals before a treadmill test and 2, 24, and 48 hours after the test. Subsequently, a group of IC patients will be randomly assigned to perform a 12-week home-based exercise training program. The investigators expect a significant increase of EMPs and EPCs after acute and chronic physical activity. We expect also a correlation between the increase of EMPs and EPCs and the improvement in walking capacity. Aim of the study is to demonstrate that acutely performed aerobic exercise could be able to promote the mobilization of EMPs and EPCs in patients with IC and that endothelial progenitor cells mobilization could play a pivotal role in exercise induced improvement of walking performance and endothelial function in subjects with IC.
The objective of this clinical investigation is to evaluate, in a controlled setting, the long-term (up to 12 months) safety and efficacy of the Solaris Vascular Stent Graft (Scitech) in clinical settings when used according to the indications of the IFU.
The objective of this protocol is to test the effectiveness of a Jumpstart intervention on patient-centered outcomes for patients with chronic illness by ensuring that they receive care that is concordant with their goals over time, and across settings and providers. This study is particularly interested in understanding the effect of the intervention to improve quality of palliative care for patients with Alzheimer's disease and related dementias (ADRD) but will also include other common chronic, life-limiting illnesses. The specific aims are: 1. To evaluate the efficacy of the Survey-based Patient/Clinician Jumpstart compared to the EHR based clinician Jumpstart and usual care for improving quality of care; the primary outcome is EHR documentation of a goals-of-care discussion from randomization through hospitalization or 30 days. Secondary outcomes include: a) intensity of care outcomes (e.g., ICU use, ICU and hospital length of stay, costs of care during the hospitalization, 7 and 30 day readmission); and b) patient- and family-reported outcomes assessed by surveys at 3 days and 4 weeks after randomization, including occurrence and quality of goals-of-care discussions in the hospital, goal-concordant care, psychological symptoms, and quality of life. 2. To conduct a mixed-methods evaluation of the implementation of the intervention, guided by the RE-AIM framework for implementation science, incorporating quantitative evaluation of the intervention's reach and adoption, as well as qualitative analyses of interviews with participants, to explore barriers and facilitators to future implementation and dissemination.
Lower extremity peripheral artery disease (PAD) is a major health problem leading to significant morbidity and even mortality. Patients with superficial femoral artery stenosis make up an important proportion of patients with PAD, and since this type of involvement was reported to be most commonly associated with intermittent claudication, this patient population has been subject to intensive research on methods to prevent disease progression and further complications. Endovascular treatment has become the first-line treatment for low-complexity femoropopliteal (FP) lesions classified as TASC (Trans Atlantic Inter-Societal Consensus) A and B. Conversely, in case of more extensive lesions (TASC C), this treatment is still under debate because of a primary permeability that is difficult to maintain over time. Recently, studies have shown the interest of drug eluting technologies in the treatment of TASC A & B femoral-popliteal lesions, by significantly improving patency rates compared to uncoated balloons or stents. In this context, the endovascular treatment of FP complex lesions (TASC C) continues to develop widely. During endovascular treatment, the quality of the artery preparation has recently been identified as a factor improving outcomes. The dilatation of the artery with an uncoated balloon or POBA (Plain Old Balloon Angioplasty) is the reference method performed before stent placement or drug-coated balloons. However, some new alternatives to prepare the artery have emerged, using no more dilatation but atherectomy (Jetstream™ system). Atherectomy appears to reduce the risk of dissections and bailout stenting and improve the acute procedural results. Its long term outcome, when associated with drug coated balloons (DCB), has recently been demonstrated in the USA to be superior to angioplasty in a single center study JET-SCE. The purpose of this study is to evaluate the efficacy and the feasibility of atherectomy, using the Jetstream™ artery preparation associated to DCB treatment (Ranger™ Paclitaxel-Coated balloon), in symptomatic patients with claudication (Rutherford 2 and 3) and with complex de novo FP arterial lesions (TASC C).
The PATHFINDER I Registry is a prospective, non-randomized, single arm, multicenter observational study. It is a pilot registry study towards a subsequent large pivotal phase registry. This pilot registry is aimed to evaluate the performance (peri-procedural) and clinical outcomes (intermediate and long-term) of the AURYON™ Atherectomy System, within the initial launch phase of the product in the market.
The primary objective of the TORUS 2 IDE Clinical Study is to evaluate the safety and effectiveness of the TORUS Stent Graft System in the treatment of obstructive atherosclerotic lesions of the native SFA or the superficial femoral and/or proximal popliteal arteries.
The objective of this clinical evaluation is to evaluate the immediate and long-term (up to 36 months) outcome of the MOTIV™ Bioresorbable Scaffold (Reva Medical) in a controlled prospective investigation for the treatment of patients with rest pain or minor tissue loss (CLI) due to the presence of lesions of max 100mm in length at the level of the below-the-knee arteries.
The LimFlow System is intended for endovascular, minimally invasive procedures in patients who have a clinical diagnosis of chronic limb-threatening ischemia and who have been determined to have no surgical or endovascular treatment option (i.e., "no option").
