What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to evaluate the safety and effectiveness of the Duo Venous Stent System for people with chronic venous insufficiency, a condition where obstructed blood flow through the veins causes leg pain and swelling. The trial targets individuals with a significant blockage in a leg vein requiring stent treatment. Ideal candidates experience symptoms like leg pain or swelling due to a vein blockage in one leg. Participants must be able to walk, even with assistance from a device like a cane. As an unphased trial, this study offers participants the chance to contribute to valuable research that could enhance treatment options for chronic venous insufficiency.

Do I need to stop my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

What prior data suggests that the Vesper DUO Venous Stent System is safe for treating chronic venous insufficiency?

Research has shown that the Duo Venous Stent System is generally safe for people. One study found that 98.7% of patients did not experience major safety issues with the stent, surpassing the target goal of 89.0%. This indicates strong safety performance. Other research has found that up to 12 months after treatment, the stent remained safe and effective for treating certain vein blockages. Additionally, tests up to 180 days revealed no major safety concerns, indicating that the stent is usually well-tolerated by most patients. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike standard treatments for chronic venous insufficiency that often involve compression therapy or surgical vein stripping, the Duo Venous Stent System offers a minimally invasive solution. This stent system is designed to provide structural support to veins, potentially improving blood flow more effectively and with less recovery time. Researchers are excited about its ability to address vein blockages directly, which could offer faster relief of symptoms compared to traditional methods.

What evidence suggests that the Duo Venous Stent System is effective for chronic venous insufficiency?

Research has shown that the Duo Venous Stent System, which participants in this trial will receive, effectively treats chronic venous insufficiency, a condition where blood doesn't flow properly through the veins. In the VIVID trial, patients reported improvements based on several measures, such as the Venous Clinical Severity Score and quality of life assessments. These improvements persisted over a year, indicating that the stent helps ease symptoms and enhance daily life. Additionally, using a balloon to open the vein and placing a stent has proven effective for people with serious vein problems, like blockages. Trials have found the system safe for humans, with no major safety issues reported. ^{2 3 4 5 6}

Are You a Good Fit for This Trial?

Adults over 18 with chronic venous insufficiency, May-Thurner Syndrome, or deep vein thrombosis who need a stent and can follow post-treatment care. Must not be pregnant/breastfeeding, have a BMI under 40, no recent COVID-19 infection or symptoms, and no history of certain blood disorders or allergies to the stent materials.

Inclusion Criteria

My veins near the target area are healthy enough for treatment.

Your body mass index (BMI) is less than 40.

I had symptoms of a deep vein clot before getting a DUO Stent.

Exclusion Criteria

Your iliofemoral veins are not the right size for the available DUO Stent implants.

You have had a condition called Heparin Induced Thrombocytopenia in the past.

My blood does not clot properly, and treatment has not worked to fix it.
