Filter by:This is a Phase 4, randomized clinical trial to evaluate whether GNX80 vs. placebo, prescribed for 6 months to patients with Intermittent Claudication(IC) would lead to an improvement in the walking distance.
The objective of the proposed study is to define independent parameters for the diagnostic assessment of the perfusion situation of the calf muscle based on multispectral optoacoustic tomography (MSOT) in a cross-sectional collective of patients with PAD in Fontaine stage II (intermittent claudication) and a healthy control collective (study group 1). The results will be validated using an independent validation group (study group 2).
Intermittent claudication is the most common symptom of peripheral arterial disease (PAD). The recommended therapy is supervised exercise therapy combined with lifestyle counselling, provided by a physiotherapist. Ideally, during the treatment process patients' values and preferences are incorporated with evidence-based knowledge; shared decision making (SDM). Evidence shows the use of SDM in daily practice is scarce. Therefore, personalized outcome forecasts which provide insight into an individual's personal prognosis (called KomPas) were implemented in 2020. Now, as a next step, KomPas is further developed into a guideline-based clinical decision support system. The result is called KomPas+, a tool which integrates the person-centered approach of KomPas with the guideline recommendations for the conservative treatment of people with intermittent claudication.The primary objective of this study is to evaluate the impact of implementing KomPas+ in the physiotherapeutic treatment of patients with intermittent claudication on functional walking distance and health-related quality of life. Secondary, the level of SDM and person-centeredness of physiotherapists using KomPas or KomPas+ will be assessed. Third, the implementation process will be evaluated.
Peripheral arterial disease (PAD) affects over 20% of aged adults and is very common among Veterans due significant tobacco use. PAD is due to the progressive blockage of peripheral arteries, predominantly to the legs, and results in intermittent claudication (IC) or recurrent muscle pain with activity secondary to insufficient blood supply. Those with PAD and IC experience a progressive decline in walking and poor quality of life. There is no effective medical treatment for PAD and IC. Metformin is a safe and effective treatment for Type 2 diabetes but it can also reduce inflammation, oxidative stress, and improve energy requirements as well as improve blood flow to the legs. Therefore, the investigators will test the ability of Metformin to improve overall functional status, reduce PAD progression, and reduce systemic inflammation in Veterans suffering from PAD and IC in a randomized, placebo controlled trial: Metformin BenefIts Lower Extremities with Intermittent Claudication (MOBILE IC) Trial. The success of this trial may identify a safe and effective treatment for PAD and IC.
The most common clinical presentation of lower extremity arterial disease is intermittent claudication. Current understanding of the pathophysiology of intermittent claudication, as well as its treatment options are limited. The progression of the disease may lead to lower limb amputation, which is devastating for patients' quality of life and is a huge socio-economic burden to society. Current study allows to determine the acute local metabolomic alterations in the ischaemic limb of the patient with intermittent claudication, and investigate the associations between the metabolomic alterations and the patient's maximal walking distance. This provides potentially valuable insight into the pathophysiology of this disease, and helps lay the groundwork for identifying potential novel targets for instituting more effective therapies for this high-risk population.
Supervised exercise for intermittent claudication is a first line therapy for peripheral arterial disease, as recommended by the National Institute for Health and Clinical Excellence and the European Society for Vascular Surgery. However 2/3 of British trusts cannot implement this due to gym availability, costs, travel time and the requirement for social distancing. During the COVID-19 lockdown the investigators successfully performed a feasibility study for remotely supervised exercise using an electronic walking log and fortnightly video calls with a physiotherapist. RESET2 aims to compare the benefits of and adherence to remotely supervised exercise with self-directed exercise to absolute walking distance.
This first-in-human clinical feasibility study will evaluate the safety and performance of the R3 Vascular MAGNITUDE® Bioresorbable Drug-Eluting Scaffold and Delivery System in patients undergoing treatment for peripheral arterial disease severe enough to have significantly reduced the blood supply to their leg. The severe reduction in blood flow causes lifestyle limiting leg pain for these patients, and may lead to amputation of the affected limb due to the loss of tissue in the leg or foot from ulcers or gangrene. The investigational device being studied in this trial is intended to restore blood flow to the affected limb, providing symptomatic relief to the patient and reducing the risk of limb amputation. The scaffold is a type of vascular stent placed within the diseased artery below the knee to improve blood flow. Unlike commercially available metallic stents which are permanently placed within the artery, the MAGNITUDE® Bioresorbable scaffold is made of a polymer material that will completely dissolve away over time, providing the support necessary to the artery while it is healing after the treatment procedure and then slowly disappearing from the artery once that support is no longer needed. The investigational scaffold has been successfully used to treat vascular blockages in the coronary arteries of the heart, but the RESOLV I study will be the first time this device has been used to improve blood flow in the arteries of the lower leg. Patients enrolled in this study may have up to three vascular blockages in their lower leg arteries treated with the MAGNITUDE® Bioresorbable scaffold, and then will be assessed over the course of the following five years to evaluate whether the investigational treatment was successful in safely alleviating their leg pain and other symptoms.
This study will focus on people with claudication from peripheral arterial disease. The investigators are researching whether a multicomponent therapeutic can increase the production of Nitric Oxide in the blood and whether that leads to an improvement in pain free walking distance and overall physical activity.
Cardiovascular disease represents a considerable economic burden to society and effective preventive measures are necessary. Patients with peripheral arterial disease (PAD) have a severe impairment of functional ability, namely in walking distance due to muscle ischemia defined as intermittent claudication (IC). The discomfort related to IC contributes to a sedentary lifestyle, decreasing physical fitness level, aggravating cardiovascular risk factors leading to disease deterioration. Exercise programs are an effective, low-cost, low-risk option compared with more invasive therapies for IC. Home-based exercise therapy (HBET) is structured, unsupervised, self-directed programs that take place in the personal setting of the patient rather than in a clinical setting. HBET program implementation is feasible and eliminates barriers such as transportation issues, proximity to clinics, and conflicts with occupational responsibilities. Even though these programs have shown to be effective at improving walking performance and distance, their results fall below those seen in Supervised Exercise Therapy (SET) programs. Thus, innovative home-based walking programs need to be developed in order to improve results and make exercise therapy available to a larger percentage of the population. The use of Information and communication technology (ICT) tools for self-monitoring is considered key to change long-term behavior. The WalkingPAD project aims to develop health technology assessment methods and evaluate personal health intervention strategies. Investigators intend to demonstrate the technical feasibility and economic viability of a personalized medicine application in real-life healthcare settings. This project intends to find evidence for three major questions: Does an M-health monitored home-based exercise program supported by a virtual assistant empowers commitment to exercise plan and allows remote control of plan accomplishment? Is it superior to an M-health monitored home-based exercise program supported by a behavioral motivational intervention, in increasing maximum walking distance? Is it superior to a self-monitoring exercise, with a specific self-designed walking plan in the residence area, in increasing maximum walking distance?
Intermittent claudication is the most common manifestation of peripheral arterial disease, a common cardiovascular disease that causes blocked blood vessels (arteries) in the leg. Symptoms consist of persistent pain in one or both legs during exercise that is relieved with rest. Evidence suggests that high levels of uninterrupted sitting and sedentary behaviour are associated with cardiovascular disease risk, mortality and all-cause mortality. One of the main goals for treating people with intermittent claudication, is increased participation in physical activity. Supervised Exercise Programmes are recommended however these are not well tolerated and compliance is low. Alternative exercise, including short bouts of physical activity to break up sedentary time, has been suggested to help improve physical function. This study will investigate whether alternative exercise, in the form of breaking up prolonged sitting time, will improve physical function in patients with intermittent claudication. Patients will be screened during their routine clinic appointment at Glenfield Hospital. All other study activity will take place at the patients home. Activity monitors will be worn for up to 8 days at baseline and follow-up, measuring step count and time, inactivity, activity time and intensity, and sleep duration. Participants will also be expected to wear activity monitors for the duration of the 8-week intervention to measure steps. Participants will be in the study for up to 18 weeks in total.
