Active clinical trials for "Vascular Diseases"

A randomised pilot study assessing the acceptability and feasibility of utilising neuromuscular stimulation devices to enhance post-operative rehabilitation and recovery after general, vascular and urological surgery procedures.

The primary objective of this study is to is to assess the ability of retina specialists to successfully administer, via an intravitreal (IVT) injection, a 2 mg dose of ABP 938, using the ABP 938 aflibercept prefilled syringe (PFS), compared to a 2 mg dose of aflibercept using the aflibercept PFS.

Creating a 12 month profile of Vascular Surgery Admissions aims to inform service delivery and optimise patient care resources. There is a gap in the literature pertaining to this topic, particularly from an Irish perspective. This research could inform a clinical pathway to reduce LOS for patients cared for by the Department of Vascular Surgery.

The REQUIRE STUDY is a multi-center, randomized, double-blind, sham-controlled study, which aims to confirm the efficacy and safety of PRDS-001 (ReCor Medical Inc. Paradise in Europe) for renal denervation therapy in patients with treatment resistance hypertension, in comparison with the sham procedure.

To evaluate the benefits of Ayurvedic SUVED & REIMMUGEN Colostrum for reduction/reversal of symptoms and study clinical progress in Vascular disease; CAD, CAV, Stroke, DVT patients.

Patients scheduled for major extremity lower amputation to receive bone marrow cells (cBMA) injected IM in the leg proximal to the amputation in the index limb to prevent ischemic wound complications after surgery.

The enormous and rapidly growing burden of Heart Failure with Preserved Ejection Fraction (HFpEF) has led to a need to understand the pathogenesis and treatment options for this morbid disease. Recent research from the investigator's group and others have shown that pulmonary hypertension (PH) is highly prevalent in HFpEF, and right ventricular (RV) dysfunction is present in both early and advanced stages of HFpEF. These abnormalities in the RV and pulmonary vasculature are coupled with limitations in pulmonary vasodilation during exercise. There are no therapies directly targeted at the pulmonary vasculature that have been clearly shown to be effective in HFpEF. A recent study by Mayo Clinic Investigators has demonstrated pulmonary vasodilation with dobutamine (a beta 2 agonist) in HFpEF. As an intravenous therapy, this is not feasible for outpatient use. In the proposed randomized, placebo-controlled double blinded trial, the investigators seek to evaluate whether the commonly used inhaled bronchodilator albuterol (a beta 2 agonist), administered through a high-efficiency nebulizer device that achieves true alveolar drug delivery, improves pulmonary vascular resistance (PVR) at rest and during exercise in patients with HFpEF as compared to placebo. This has the potential to lead to a simple cost effective intervention to improve symptoms in HFpEF, and potentially be tested in other World Health Organization (WHO) Pulmonary Hypertension groups. PVR is an excellent surrogate marker for pulmonary vasodilation and has been used in previous early trials of PH therapy.

Unifusol (R) is a solution of arginine sodium succinate for intravenous infusions. Its effects include vasodilation, protection of inner layer of blood vessels and improvement of blood viscosity. The present phase I study is aimed to evaluate the safety and tolerability of Unifusol infusions in healthy volunteers.

Polypoidal choroidal neovasculopathy (PCV) is a subtype of wet age related macula degeneration (AMD) occuring more commonly in the Asian population. Besides the phenotypic differences, PCV is thought to have a lesser response to anti VEGF therapy which is the mainstay of treatment for other typical wet AMD. Recent trial data suggest that a combination with photodynamic therapy may help in the visual and anatomical outcome of PCV, and emerging evidence shows favourable outcomes the newer anti VEGF agent, aflibercept 2mg monotherapy. These trials however, have assessed aflibercept in a strict 2mg every 8 weekly regime. In the clinical setting, a significant an unmet need in the management of PCV is a tailored treatment regime. Here we propose a treatment regimen based on disease activity for PCV with aflibercept mono therapy. A limitation of the 2q8 regime is that it is fixed and does not vary regardless of polyp closure or anatomical outcome at the first time point of assessment (month 3). We hypothesize that after the initial 3 monthly injections of aflibercept, about 50% of PCV will close and become quiescent, and in the remaining 50%, a further 3 monthly injections will increase overall polyp closure rate. After a loadings phase of either 3 or 6 months, all eyes will start on a treat and extend regime (T&E), with a minimum period of 8 weeks and a maximum of 12 weeks between treatments with 2 week increments if PCV remains quiescent. The proposed study aims to evaluate the efficacy of a modified treat and extend regime based on disease activity with aflibercept monotherapy for PCV.

This study will assess the adjuvant benefit of a neuromuscular electrical stimulation device to standard treatment of supervised exercise in patients suffering from symptoms and effects of lower limb Intermittent Claudication.
