NCT ID: NCT03494816 Recruiting - Clinical trials for Renal Cell Carcinoma

Study of Axitinib for Reducing Extent of Venous Tumour Thrombus in Renal Cancer With Venous Invasion

NAXIVA
Start date: December 15, 2017
Phase: Phase 2
Study type: Interventional

NAXIVA is a study of axitinib in patients with metastatic and non-metastatic renal cell carcinoma with venous invasion. Patients will be given axitinib (twice daily) for 8 weeks (at an escalated dose) and the response of the venous invasion will be assessed. Blood, urine and tumour tissue samples will be taken prior to and during therapy to evaluate biomarkers of treatment response. The primary objective is to assess the response of the thrombus to axitinib. Its thought that axitinib will reduce the extent of the thrombus in the inferior vena cava will reduce the extent of surgical intervention.

NCT ID: NCT03491891 Recruiting - Stent Thrombosis Clinical Trials

Factors Contribute to Very Late Stent Thrombosis After New Generation DES Implantation in China

Start date: December 10, 2017
Phase:
Study type: Observational [Patient Registry]

We sought to identify and verify independent correlates of Very Late Stent Thrombosis after the implantation of new generation drug eluting steng in China from an analysis of multicenter registries.

NCT ID: NCT03490552 Recruiting - Thrombosis Clinical Trials

RNA Sequencing Analysis in Large Vessel Occlusion Stroke DATA Bank

RNASA-LVOSB
Start date: January 1, 2018
Phase: N/A
Study type: Interventional

Introduction: the source of embolic stroke , in thrombotic embolism , is of unknown origin in 30-40% of cases. Fortunately , Mechanical thrombectomy provide a direct method to retrieve the stroke-incriminated clots from stroke patients for possibility of exo-autopsy analysis.

NCT ID: NCT03489395 Recruiting - Atrial Fibrillation Clinical Trials

A Pilot Study on Edoxaban for the Resolution of Left Atrial Thrombosis in Patients With Non-valvular Atrial Fibrillation

Start date: January 30, 2018
Phase: Phase 2
Study type: Interventional

Isolated reports have indicated that complete Left Atrial or Left Atrial Appendage thrombus resolution may be achieved also with use of oral Factor Xa inhibitors, which have demonstrated the same efficacy but a better safety profile compared to warfarin. The aim of this open-label pilot study is to investigate the percentage of Left Atrial /Left Atrial Appendage thrombus resolution with edoxaban therapy in patients with non-valvular atrial fibrillation. The subordinated aim is the design a larger and longer study to compare edoxaban and warfarin in the same patient population. With the exception of few case reports, there are no data in the same patient population referred to antithrombotic treatments other than vitamin K antagonists.

NCT ID: NCT03489135 Not yet recruiting - Clinical trials for Deep Vein Thrombosis Leg

The Venous Thrombus Extraction (VETEX) Clinical Study: A Preliminary Investigation

VETEX
Start date: July 1, 2018
Phase: N/A
Study type: Interventional

This is an open label, prospective, non-randomised, multi-centre first-in-human evaluation of the Vetex Thrombectomy Device for treatment of acute iliofemoral deep vein thrombosis (DVT)

NCT ID: NCT03483207 Not yet recruiting - Clinical trials for Mesenteric Vein Thrombosis

Acute Mesenteric Venous Thrombosis.. in Assiut University Hospital Management Controversies

Start date: April 1, 2018
Phase: N/A
Study type: Interventional

Initial treatment in the management of acute mesenteric vein thrombosis (MVT) is controversial. Some authors have proposed a surgical approach, whereas others have advocated medical therapy (anticoagulation). In this study, the investigators analyzed and compared the results obtained with surgical and medical treatment to determine the best initial management for this disease.

NCT ID: NCT03483181 Recruiting - Thrombosis Clinical Trials

Thromboprophylaxis in Patients Undergoing Orthopedic Surgeries; Using Propensity Score Matching

Start date: January 1, 2018
Phase:
Study type: Observational

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common post-operative complication. The necessity for anticoagulant therapy after orthopedic surgeries is widely understood, but treatment administration patterns in the prevention of venous thromboembolism (VTE) after orthopedic surgeries during the hospital stay have yet to be examined. The main objective of this study is to perform a comparative effectiveness review examining the benefits and harms associated with venous thromboembolism prophylaxis in patients undergoing orthopedic surgeries. It is around efficacy and safety evaluation of using anticoagulant for thromboprophylaxis in patients undergoing orthopedic surgeries taking into the account the reliable selection of patients most benefit. The aims of this study is to analyze patient records in teaching hospitals database of our country (including: Hanoi Medical University, Bach Mai Hospital, Cho Ray Hospital, Viet Duc University Hospital) and compare the outcomes and costs between different types of anticoagulant medications that were prescribed for the prevention of VTE following orthopedic surgeries. This analysis will assess and quantify the outcomes, resource utilization, and cost of care for patients receiving rivaroxaban or enoxaparin. The outcomes of interest include the occurence of DVT and PE, rates of major bleeds, medical resource utilization, and total costs (medical plus pharmacy).

NCT ID: NCT03479489 Enrolling by invitation - Clinical trials for External Hemorrhoid Thrombosed

Use of Human Dehydrated Amnion Chorion Allograft in Closed Hemorroidectomy

Start date: February 5, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to determine the safety and effectiveness of human dehydrated amnion chorion allograft in closed hemorrhoidectomy as assessed by patient and wound assessments.

NCT ID: NCT03477968 Not yet recruiting - Clinical trials for Venous Thromboembolism

ThRombosis ExclUsion STudy

TRUST
Start date: June 2018
Phase:
Study type: Observational

The purpose of this study is to demonstrate the ability of new D-Dimer assay combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism (PE) or Deep Venous Thrombosis (DVT) in a 3 month follow-up.

NCT ID: NCT03477149 Recruiting - Bleeding Clinical Trials

EASYX-1 : A Multicenter Study on Safety and Efficacy of Easyx Liquid Embolization Agent Used in Five Separate Indications

EASYX-1
Start date: March 30, 2018
Phase: N/A
Study type: Interventional

The EASYX™ Liquid Embolic is a new injectable, precipitating polymeric agent for the obliteration of vascular spaces through direct puncture or catheter access performed under X-ray guidance. The embolic liquid is an iodinized Polyvinyl Alcohol (PVA) Polymer ether. Iodine groups are covalently grafted to the PVA polymer backbone, whereby a stable nondegradable polymer with the desired features is created. The resulting polymer is dissolved in Dimethyl Sulfoxide (DMSO). EASYX™ is CE-marked since December 2016 and has been used in humans a few time for type II endoleaks, portal vein and varicocele (<10 cases at the date of submission). The purpose of this study is to evaluate the safety and efficacy of EASYX™ embolization liquid for the percutaneous treatment of vascular lesions, i.e. embolization of varicocele, type II endoleaks, portal vein before surgery, active peripheral bleeding or angiomyolipoma (AML).
