Active clinical trials for "Vascular Diseases"

The purpose of this research study is to determine if the transplant of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in the severely diseased ischemic limb (leg). In this study the safe use of this combination of stem cells and its effects on making new blood vessels will be evaluated. Limb Ischemia (LI) is a severe obstruction of the arteries which seriously decreases blood flow to the extremities (mainly feet and legs) and has progressed to the point of severe pain and even skin ulcers or sores. LI needs comprehensive treatment since the condition will not improve on its own. The overall goal of treatment is to reduce the pain and increase blood flow to improve symptoms or save the leg or feet. In many cases, current options for treatment including medications, surgery or endovascular procedures have not been successful. In the last few years, investigators have explored therapies aimed to increase blood flow to the ischemic vessels by transplanting cells that will promote the development of new vessels in the diseased leg. The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriate blood supply to the leg. Patients eligible to participate in this study are those suffering from poor circulation or severe leg blockages, which are not candidates for surgical procedures. Once the mixture of stem cells is prepared and the patient's bone marrow is ready, cells will be transplanted into the calf muscle of the diseased leg. Clinical studies to evaluate if the transplant works and is safe will be performed up to 1 year after cell transplant.

Primary objective is to demonstrate the superiority of riferminogene pecaplasmid (XRP0038/NV1FGF) over placebo in the prevention of major amputation above the ankle of the treated leg or of death from any cause, whichever comes first, in critical limb ischemia (CLI) patients with skin lesions. Secondary objectives are to evaluate: The efficacy of riferminogene pecaplasmid versus placebo for delaying the time to major amputation; The efficacy of riferminogene pecaplasmid versus placebo for delaying the time to death; The safety of riferminogene pecaplasmid in the study population.

The primary focus of the trial is safety and efficacy of the intra-muscular implantation of either bone-marrow, or peripheral blood mononuclear cells, in critical limb ischemia, as judged by the proportion of patients which are alive without major amputation 6 months after inclusion.

The purpose of this study is to examine the effects of two diabetes medications, rosiglitazone and pioglitazone, on markers of vascular disease in subjects with type 2 diabetes.

This is a prospective, multicenter, non-randomized, single arm, pivotal trial. The main objective of this study is to demonstrate the safety and effectiveness of the IDev SUPERA® Nitinol Stent System in treating subjects with obstructive superficial femoral artery (SFA) disease. The primary endpoint will be the primary patency of the SFA evaluated at 12 months. The outcome will be compared to a performance goal based on clinical trials of percutaneous transvenous angioplasty (PTA) alone.

The The purpose of this study is to determine the safety of PLX-PAD single dose, Intra-muscular injection for the treatment of CLI patients.

To study the early safety and performance of the Shockwave Medical System in subjects to demonstrate that the device can safely and effectively deliver localized energy for the treatment of vascular disease.

This Phase I/II study will investigate the safety and tolerability of intravitreally administered 0.5mg and 1.0 or 2.0mg Ranibizumab in three monthly doses followed by a 9 month period of criteria-based, as-needed retreatment and 12 month of drug safety follow up in subjects with exudative polypoidal choroidal vasculopathy (PCV) for a total of 24 months.

We seek to determine if the use of the SafeSeal(TM) topical hemostasis patch is associated with reductions in time to hemostasis and time to ambulation compared to standard manual compression after arterial sheath removal following percutaneous coronary and peripheral intervention. We further seek to assess the safety of the SafeSeal patch compared to manual compression.

To assess the effects of L-arginine upon functional status (treadmill exercise testing; quality of life) and limb blood (by mercury strain gauge plethysmography) in peripheral arterial disease.
