Active clinical trials for "Intermittent Claudication"

The purpose of this Phase 2 clinical research study is to examine the safety of an experimental gene transfer agent, Ad2/HIF-1α/VP16, and its ability to stimulate the growth of new blood vessels from existing blood vessels (a process called angiogenesis) in an attempt to improve the flow of blood in the legs of patients with peripheral arterial disease (PAD). Specifically, this study will enroll patients with severe intermittent claudication (IC) which is the stage of PAD in which a patient's walking ability is severely limited, causing pain in the legs upon exercise due to inadequate blood flow to the muscles of the lower limbs.

This study will determine if a highly standardized herbal extract of the leaves of the Ginkgo Biloba tree will benefit patients who have pain on walking due to narrowing of the arteries of the legs.

To identify a correlation between Toe Brachial pressure Index (TBPI) and Acceleration time of the pedal vessels. The aim would then to use this data to design a clinical study assessing the relationship between PAT and wound healing in patients with PAD.

Some people experience a cramp-like leg pain during walking that is relieved only by rest. This is called intermittent claudication (IC) and it is a common symptom of peripheral arterial disease. Patients with IC struggle to walk, which in turn lowers their quality of life. The intensity of IC pain experienced during walking depends on several factors, including the type of footwear worn. For example, non-supportive shoes may make the calf muscles work harder during walking, leading to earlier and more-severe symptoms of IC. A member of the research team has developed a shoe that reduces the work done by the lower-leg muscles during walking. Preliminary data indicate that, when wearing these "unloading shoes", people with IC were able to walk further without pain as compared with when wearing a normal pair of shoes. The current project aims to provide further information on the usefulness and acceptability of these shoes. Forty people with IC will complete a set of three walking tests on two separate occasions; once whilst wearing the unloading shoes, and once whilst wearing some normal shoes. The participants will then be given a pair of unloading or normal shoes to wear for two weeks, after which we will collect information on how acceptable the shoes were to wear via a survey of all participants and one-to-one interviews with a subset of participants.

This is a prospective, randomized, multi-center, single-blind study to demonstrate the safety and effectiveness of the CVI Paclitaxel-coated percutaneous transluminal angioplasty (PTA) balloon versus bare PTA balloon for the treatment of patients with de novo occluded/stenotic or reoccluded/restenotic lesions of the superficial femoral (SFA) and popliteal arteries.

The objective of the study is to establish the safety profile of Intramuscular PLX-PAD injections and to evaluate the clinical efficacy of it in IC subjects comprising of 4 treatment groups: Double treatment of PLX-PAD low dose Double treatment of PLX-PAD high dose Double treatment of Placebo Single treatment of PLX-PAD high dose and additional treatment of Placebo. Subjects will receive the assigned treatment twice to the affected leg, within 12-weeks interval between each treatment. The study will be comprised of 5 stages: Screening period of up to 4 weeks,first treatment of PLX-PAD or placebo followed by additional injection after 12 weeks and with follow-up of 12 months post second injection

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.

A Randomized, Blinded Comparison of Surgical Intervention with the Coflex® Interspinous Implant versus Surgical Decompression for Patients with Intermittent Neurogenic Claudication caused by Lumbar Stenosis

Rehabilitation is the first intention treatment of peripheral arterial disease (PAD) with claudication. Initially proposed in the sixty's, rehabilitation programs dedicated to patients with PAD have recently been proved effective and defined in many guidelines. Supervised walking training on treadmill is recommended. Usually patients walk up to a mild or moderate pain (evaluated at 3 or 4 on the claudication pain scale; maximum pain =5), then stop until pain completely subsides and walk again . The Artex study assesses the efficacy of a fractionated mode of training avoiding pain by alternating short sequences of intensive training and active recovery (without rest).

Background: Muscle atrophy and reduced leg strength are related to exercise intolerance in patients with intermittent claudication (IC), suggesting that strength training (ST) could improve exercise performance in these patients. Objective: Analyze the effects of ST in walking capacity in patients with IC comparing with walking training (WT) effects. Intervention: Patients were randomized into ST and WT. Both groups trained twice a week, for 12 weeks, at the same rate of perceived exertion. ST consisted of 3 sets of 10 repetitions of whole body exercises. WT consisted of 15 two-minute bouts of walking intercalated with 2 minutes of resting. Measurements: Walking capacity, peak VO2, walking economy, ankle brachial index, ischemic window and knee extension strength
