NCT ID: NCT03368313 Not yet recruiting - Clinical trials for Deep Vein Thrombosis

Non-elastic Compression Garment Therapy Versus Control for Deep Vein Thrombosis

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

The objective of the study is to conduct a Bayesian randomized trial comparing non-elastic compression garments applied with high pressure (Circaid group) with no compression (control group) in reducing signs and symptoms in the acute stage of DVT and subsequent postthrombotic syndrome. With a hypothesis that the Circaid group will present a quicker and more marked reduction of pain and leg swelling in the acute stage of DVT, as well as a 20% decrease in the frequency of postthrombotic syndrome within six months from the time of diagnosis of the acute deep vein thrombosis episode.

Chronic Venous Thrombosis: Relief With Adjunctive Catheter-Directed Therapy (The C-TRACT Trial)

C-TRACT
Start date: May 7, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to determine if the use of image-guided, endovascular therapy (EVT) is an effective strategy with which to reduce Post Thrombotic Syndrome (PTS) disease severity and improve quality of life in patients with established disabling iliac-obstructive post thrombotic syndrome (DIO-PTS).

Novel PET/CT and Treatment Strategies to Reduce PTS Following DVT

Start date: December 20, 2017
Phase: N/A
Study type: Interventional

The goal of this study is to develop strategies that will improve outcomes for patients with deep vein thrombosis (DVT), using in vivo FDG-PET inflammation imaging to better predict the development of the post-thrombotic syndrome (PTS). New approaches are needed to improve the outcomes of patients with DVT, a disease that affects up to 600,000 patients per year in the US alone. DVT acutely places patients at risk of death from pulmonary embolism and causes 50,000 deaths annually in the US. Moreover, up to 30-50% of patients will develop PTS, an illness characterized by inflammation-driven fibrotic vein wall injury, and persistent thrombus obstruction. PTS occurs despite anticoagulant therapy, and produces chronic disability from leg pain, heaviness, edema, skin pigmentation, and ulcers; some patients may even require amputation. PTS impairs quality of life to the same extent as chronic obstructive pulmonary disease or diabetes. Therefore new diagnostic insights into PTS are urgently needed. There are several major challenges to improve outcomes in PTS: A) Limited in vivo knowledge regarding inflammation and the development of PTS; B) L Lack of predictive approaches to identify patients at high risk for PTS that will preferentially benefit from novel therapies. Recently, our laboratories have harnessed FDG-PET molecular imaging to illuminate DVT inflammation in vivo, and to provide a new strategy to diagnose recurrent DVT, a vexing clinical problem (Hara et al. Circulation 2014). We now propose to further develop FDG-PET to improve outcomes in DVT and PTS. The objective of this application is to develop FDG-PET as an inflammation imaging approach to assess DVT inflammation and predict risk of developing PTS in human subjects; Hypothesis 1A: Inflammatory activity in DVT (quantified acutely, using FDG-PET imaging within 0-7 days after DVT) will predict PTS incidence (primary) and severity (secondary) within a 24 month follow-up period. Hypothesis 1B: Inflammatory activity in DVTs (quantified sub-acutely, using FDG-PET imaging within 21-28 days after DVT), will predict PTS incidence and severity. Eighty patients with DVT will be imaged using FDG-PET/CT acutely (0-7 days of DVT diagnosis), and sub-acutely (21-28 days after diagnosis). Subjects will be evaluated repeatedly for up to 2 years to detect clinical evidence of PTS (Villalta score), ultrasound findings for structural venous injury, and soluble biomarkers of systemic inflammation. Subsequently, we will evaluate the relationship between FDG DVT activity and the development of PTS.

Physical Activity in Children at Risk of Post-thrombotic Syndrome (PACT)

PACT
Start date: December 2016
Phase: N/A
Study type: Interventional

'The PACT trial' is randomized pilot trial to demonstrate the feasibility and potential effectiveness of a personal "fitness tracker" to improve adherence to an activity regimen following an initial acute DVT in children.

Long Term Assessment of Post Thrombotic Syndrome : OPTIMEV Study ( SPOT )

SPOT
Start date: July 11, 2017
Phase: N/A
Study type: Observational

Post-thrombotic syndrome (PTS) is a frequent and burdensome complication of deep-vein thrombosis (DVT). In the absence of curative treatment of established PTS, its management is based on the prevention of its occurrence thanks to anticoagulants and compression stockings. So far, predictors of disabling PTS are unknown precluding from optimally selecting patients for invasive (early thrombus removal) or innovative/expensive treatments. In addition, little is known on the incidence of PTS in the very long-term. Objectives: To assess, 12 years after a symptomatic venous thromboembolic (VTE) event, Primary objective: incidence and severity of PTS after a lower limb DVT. Main Secondary objectives: 1. Incidence and severity of PTS according to VTE initial presentation (isolated distal DVT, isolated proximal DVT, PE + DVT). 2. Incidence and risk factors of disabling PTS Methods: Very long-term follow-up (12 years) of patients recruited in the large, multicentre, prospective, observational OPTIMEV study for a suspicion of VTE confirmed or ruled out with objective tests (Clinical Trials NCT00670540). All patients with a DVT, an isolated PE and a random selection of controls (VTE - patients without any history of VTE after the 3 years of follow-up) will first benefit from a phone-PTS assessment. Those patients presenting at least a mild venous insufficiency and a selection of controls will undergo a clinical follow-up visit with clinical and Compleat Ultra Sound (CUS) assessment of PTS/venous insufficiency and an assessment of quality of life. Perspectives: Improving our knowledge of PTS' incidence and predictors and of the impact of usual treatment. Better selecting patients eligible for invasive/innovative/expensive preventative procedures.

NCT ID: NCT03039517 Recruiting - Clinical trials for Deep Vein Thrombosis

Post Thrombotic Syndrome Prevention Study

Start date: January 2017
Phase: N/A
Study type: Interventional

This is a two arm, prospective, single center, randomized clinical trial. Subjects will be randomly assigned into one of two groups using block randomization technique in a 1:1 ratio. The control group will receive care using elastic compression stocking and the intervention group will use the ACTitouch device. Stratified randomization will occur based on whether the Deep Vein Thrombosis (DVT) has iliac or non-iliac involvement. Subjects will be followed for 2 years with clinic visits occurring at 1, 3, 6, 12, and 24 months.

Prospective Evaluation of the QoL of Patients With PTS Who Receive Compression Therapy and Sulodexide

SQUARES
Start date: September 2015
Phase: Phase 4
Study type: Interventional

This study aims to evaluate whether, in a standardised cohort of patients with mild to moderate PTS, monitored for a sufficiently long follow-up period, quality of life measured by generic instruments and disease-specific instruments evolves favourably in this patient profile. Study objective: to evaluate the evolution of quality of life in general and in the specific context of the disease of patients who have experienced an episode of deep-vein thrombosis (DVT), are affected by post-thrombotic syndrome, are subject to compression therapy and receive an additional standard venoactive agent (sulodexide 15 mg twice daily during 6 months).
