Trial Summary

What is the purpose of this trial?

This trial is testing the VenoValve System, an artificial valve that is surgically placed in leg veins. It aims to help patients with severe vein valve problems by improving blood flow. The study will check if this treatment is safe and effective. The VenoValve is a new prosthetic venous valve being tested for the first time in humans to treat chronic venous insufficiency.

Do I have to stop taking my current medications for the VenoValve trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you must be able to comply with a post-operative anticoagulation regimen, and certain conditions like chronic narcotic usage or untreated hypercoagulable conditions may affect eligibility.

What data supports the idea that VenoValve® Implant for Venous Insufficiency is an effective treatment?

The available research shows that the VenoValve® Implant is a promising treatment for chronic venous insufficiency. In a human trial, the VenoValve was tested for its safety and performance, indicating it could be a feasible option for patients with severe forms of the condition. Additionally, the study on patient selection suggests that the VenoValve is most beneficial for those with significant blood flow issues, like chronic venous insufficiency, compared to other conditions. This suggests that the VenoValve may be more effective than other treatments, which often fail or have complications over time. ^{1 2 3 4 5}

What safety data is available for the VenoValve® treatment?

The provided research does not contain specific safety data for the VenoValve® treatment or its other names like Hancock-Jaffe bioprosthetic venous valve. The articles focus on other medical devices and treatments, such as the ALLEGRA valve, Janus kinase inhibitors, and adalimumab biosimilars. Therefore, no relevant safety data for VenoValve® is available in the given research. ^{6 7 8 9 10}

Is the VenoValve® treatment a promising option for venous insufficiency?

Yes, the VenoValve® treatment is promising because it offers a new option for patients with severe venous insufficiency, a condition where blood struggles to return from the legs to the heart. Current treatments often fail, but the VenoValve® has shown potential in early studies to improve blood flow and quality of life for patients. ^{1 2 3 11 12}

Treatment Details

Interventions

• Hancock-Jaffe bioprosthetic venous valve (VenoValve®) (Bioprosthetic Venous Valve)

Trial Overview The study tests the VenoValve®, a bioprosthetic valve surgically placed into deep veins as a treatment for patients whose leg veins don’t close properly causing swelling and ulcers. It's a single-group study where all participants receive the valve to see how safe and effective it is.

Findings from Research

The VenoValve, a prosthetic venous valve, was successfully implanted in 10 patients with severe chronic venous insufficiency (C5-C6), achieving a 100% technical success rate and showing promising early results in improving clinical outcomes and quality of life after 6 months.

Patients demonstrated significant improvements, including a 61% decrease in venous clinical severity scores and a 57% decrease in pain scores, indicating that the VenoValve may be an effective treatment option for those suffering from severe CVI.

Human trial using the novel bioprosthetic VenoValve in patients with chronic venous insufficiency. Ulloa, JH., Glickman, M.[2022]

The study identified that patients with chronic venous insufficiency (CVI) classes 4 to 6, right heart hypertrophy (RHH), and right heart failure (RHF) are the most likely to benefit from a venous valve prosthesis, as simulations showed a significant reduction in mechanical stress ratios for these groups.

Conversely, patients with deep venous thrombosis (DVT) are least likely to benefit from the prosthetic valve due to low flow conditions, although the valve may be useful for post-thrombotic patients after thrombus removal and flow restoration.

A new prosthetic vein valve was successfully implanted in 10 dogs without the use of anticoagulants, showing promising results for treating venous insufficiency.

After 3 to 8 months, the prosthetic valves maintained patency and competency, indicating potential for effective long-term use in managing venous insufficiency.

A 36-year-old woman with chronic venous insufficiency successfully underwent venous valve reconstruction using prosthetic bovine monocusp patches, indicating a promising surgical intervention for this condition.

Postoperative assessments, including Doppler studies and phlebography, showed restored valvular competence and significant clinical improvement after 15 months, demonstrating the efficacy of the procedure.

Prosthetic venous valves that are mismatched in size by more than 15% significantly increase regurgitate volume, closing time, and pressure differences, which can negatively impact valve function.

To optimize the performance of venous valves and reduce wall stress, it is crucial that the size of the prosthetic valve is within 15% of the maximum vein size, as larger mismatches can double or triple the wall stress compared to normal physiological levels.

The ALLEGRA aortic valve, used in 93 patients for aortic valve stenosis or degenerated valve prosthesis, demonstrated a high implantation success rate of 97.8% and a device success rate of 94.6%, indicating its efficacy in routine clinical use.

The procedure had a low complication rate, with in-hospital all-cause mortality at 2.2% and only minor instances of paravalvular leakage, suggesting that the ALLEGRA valve is both safe and effective for patients, particularly those with a mean age of 82.5 years.

The study demonstrated that AVT02, an adalimumab biosimilar, is bioequivalent to both the EU- and US-approved reference products, with pharmacokinetic parameters falling within the acceptable range of 80% to 125% for bioequivalence.

Safety and immunogenicity profiles of AVT02 were found to be comparable to those of the reference products, indicating that it is a safe alternative for patients.

Postmarketing safety surveillance is essential for identifying rare adverse events and complications associated with biologics and biological devices that may not be detected during premarketing studies.

Adverse event reporting has led to important safety notifications and label changes, highlighting risks such as airway compromise from bone morphogenetic protein and fatal air embolisms from fibrin sealants, underscoring the need for ongoing monitoring of these products.

A study analyzing 741 adverse events reported for three biologics (adalimumab, etanercept, and infliximab) in the Portuguese pharmacovigilance system found that all three were significantly associated with increased risks of infections and neoplasms, indicating potential safety concerns.

Adalimumab and etanercept showed strong associations with specific adverse events, while infliximab was linked to a broader range of issues, including immune system disorders and respiratory problems, suggesting that each biologic may have unique safety profiles that require careful monitoring.

A new prosthetic vein valve design effectively prevents regurgitation and reduces venous reflux, showing promising results in a mock-up and prototype testing with low regurgitation values compared to no device.

The valve maintains normal antegrade flow without increasing resistance, indicating its potential as a viable surgical treatment option for chronic venous insufficiency, warranting further in vivo testing.

In a study of 27 patients with deep venous valve insufficiency, the use of a substitute valve at the popliteal vein significantly reduced ambulatory venous pressure from an average of 9.14 kPa to 5.94 kPa after surgery, indicating improved venous function.

After a follow-up period of 2-6 years, 21 out of 27 patients reported satisfactory results, suggesting that this treatment is effective and has potential for widespread application in managing venous insufficiency.
