Active clinical trials for "Peripheral Vascular Diseases"

Background - In patients with critical limb ischaemia (CLI), the infragenicular arteries are often involved. Without revascularisation, amputation often is imperative. There is a high technical success rate of endovascular revascularisation of infragenicular arteries with percutaneous transluminal angioplasty (PTA), but mid- and long-term results are disappointing as restenosis frequently occurs. Drug-eluting balloon (DEB) PTA has been shown to improve patency rates after PTA of coronary arteries. Aim To study the results of DEB-PTA compared to conventional balloon CB-PTA for the treatment of infragenicular lesions in patients with CLI. To evaluate cost-effectiveness of DEB-PTA versus CB-PTA in patients with critical limb ischemia (CLI) by quantifying the incremental cost-effectiveness ratio (ICER). Hypothesis DEB PTA results in improved patency rates compared to CB-PTA for treatment of infragenicular arterial lesions in patients with CLI. DEB-PTA is a cost-effective strategy in patients with CLI compared with CB-PTA. Methodology Multi-center, prospective, randomised parallel-group trial. Patients are eligible for enrolment if they have CLI and at least one infragenicular lesion with a maximal total lesion length of 20cm. Randomisation will be performed on a 1:1 ratio to either DEB-PTA or CB-PTA. Patients will be assessed prior and directly after the intervention, at 3, 6 and 12 months by Rutherford classification, ankle-brachial index, toe pressure and adverse events. Duplex will be performed at 3 months. Angiography will be performed before and directly after PTA and at 6 months. Primary end-point will be primary patency of the treated lesions at 6 months on angiography (defined as <50% stenosis, without re-intervention in the interim). Secondary end-points are limb salvage at 3, 6 and 12 months, primary patency of the treated lesion on Duplex at 3 months (defined as patency of the treated artery with peak systolic velocity (PSV) ≤2.0 m/sec), Rutherford classification, minor and major amputation, infrapopliteal endovascular re-intervention, patency of treated femoropopliteal sites (if applicable), infrapopliteal surgical bypass, peri-procedural complications and death at 3, 6 and 12 months. A cost-effectiveness analysis (CEA) from a societal perspective will be performed in parallel with the randomized clinical trial with a 12-month time horizon.

A multi-center, post-CE Mark study designed to evaluate the performance of the Intact Vascular Tack-IT Endovascular Stapler™ in subjects with vascular flaps (e.g.; post-angioplasty dissection) resulting from percutaneous transluminal balloon angioplasty (PTA) of superficial femoral or popliteal artery(ies).

The purpose of this study is to evaluate the efficacy of drug-eluting balloon angioplasty followed by nitinol stent implantation versus nitinol stent implantation in superficial femoral artery and popliteal artery stenosis.

This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the potential of dalcetrapib to reduce cardiovascular morbidity and mortality in patients with stable coronary heart disease (CHD), with CHD risk equivalents or at elevated risk for cardiovascular disease. Eligible patients will be randomized to receive either dalcetrapib 600 mg orally daily or placebo orally daily, on a background of contemporary, guidelines-based medical care. Anticipated time on study treatment is 4 years.

The utility of GP1101 will be evaluated relative to that of surgical bypass in the treatment of Femoral/Popliteal Arterial Symptomatic Peripheral Arterial Disease. Efficacy will be measured by comparison to a Surgical Bypass Efficacy Goal, and Invasiveness will be measured by comparison to Surgical Bypass data derived from a retrospective study.

This study is a double-blind study to evaluate the efficacy and safety of NV1FGF, a pCOR plasmid constructed by inserting the gene coding for the FGF compared to placebo in patients with severe Peripheral Arterial Occlusive Disease, Fontaine's stage IV. The efficacy was assessed by the complete healing of at least one ulcer in the treated limb, 25 week post-baseline and secondary by the rate of amputation and death.

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.

The Zilver® PTX™ Drug Eluting Vascular Stent is indicated for the treatment of symptomatic vascular disease of the above-the-knee femoropopliteal artery (ranging from 4 mm to 9 mm in reference vessel diameter) for lesions up to 7 cm long. The clinical trial is stratified by lesion length. The trial will be conducted in 2 phases, with Phase 1 enrolling patients with lesions less than 7 cm long. Phase 2 of the trial will include longer lesions (up to 14 cm long) and will be initiated upon approval by the Food and Drug Administration (FDA).

Ecraprost in lipid emulsion is being developed for the treatment of Critical leg ischemia (CLI), which is the most severe form of peripheral arterial disease (PAD); This trial is designed to assess the efficacy and safety of the drug in the treatment of CLI.

30 patients will be enrolled in a prospective, multi-center, one-arm study, enrolling patients with claudication and chronic limb ischemia scheduled for lower limb venous bypass grafting on clinical grounds with single segment autologous saphenous vein. Subjects will be followed for 5 years, with follow up visits at 1, 3, 6, 12 months, 2, 3, 4, 5, years post operation.
