The China Mail - Interim Two-Year Follow-Up Data from the VenoValve(R) U.S. Pivotal Trial to be Presented Today at the VESS 2025 Annual Winter Meeting

IRVINE, CA / ACCESS Newswire / February 7, 2025 / enVVeno Medical Corporation (Nasdaq:NVNO) ("enVVeno" or the "Company"), a company setting new standards of care for the treatment of venous disease, today announced that interim two-year follow-up data on 34 subjects from the VenoValve U.S. pivotal trial will be presented today by Dr. Matthew Smeds, Professor of Surgery in the Division of Vascular and Endovascular Surgery at Saint Louis University and Principal Investigator for the trial, at the Vascular and Endovascular Surgery Society (VESS) 2025 Annual Winter Meeting, being held February 6-9, 2025 in Breckenridge, CO. The Company has submitted a pre-market authorization (PMA) application for the VenoValve to the U.S. Food and Drug Administration (FDA), and the review process is ongoing, with a decision anticipated in the second half of 2025.

Key interim two-year follow-up data being presented at VESS includes:

• 78% of subjects (n=25/32) maintained a clinically meaningful benefit, defined as an improvement of 3 or more points in the revised Venous Clinical Severity Score (rVCSS).

• Among the responder cohort, the average rVCSS improvement increased from 6.6 points at 12 months to 8.2 points at 24 months, demonstrating increasing benefit over time.

• At 24 months, subjects continued to experience a median 75% reduction in pain, as measured by the Visual Analog Scale (VAS).

• Patient-reported outcomes also demonstrated sustained improvements across all venous specific QoL indicators (VEINES-QoL/Sym) from 12 months to 24 months.

• Among the subjects with core lab-evaluable data at 24 months, a 100% device patency rate was observed in all 27 subjects.

The rVCSS is a clinically validated scoring system used to track the progression or regression of venous diseases. The FDA previously indicated that an improvement of 3 or more points in rVCSS would be evidence of the VenoValve's clinical benefit.

"The growing body of evidence from our pivotal trial further supports the contention that the VenoValve and the SAVVE procedure is a safe and effective treatment for deep venous CVI," said Robert Berman, enVVeno Medical's Chief Executive Officer. "Positive data ultimately drives future adoption, and our plan is for our primary investigators to continue to present new VenoValve data at prestigious medical conferences in the U.S. and elsewhere throughout the year, in order to create awareness and spread the message that the long awaited solution for the millions of patients that suffer from deep venous CVI is closer to becoming a reality."

Severe, deep venous CVI is a debilitating disease that is most often caused by blood clots (deep vein thromboses or DVTs) in the deep veins of the leg. When valves inside of the veins of the leg fail, blood flows in the wrong direction and pools in the lower leg, causing pressure within the veins of the leg to increase (venous hypertension). Symptoms of severe CVI include leg swelling, pain, edema, and in the most severe cases, recurrent open sores known as venous ulcers. The disease can severely impact everyday functions such as sleeping, bathing, dressing, and walking, and is known to result in high rates of depression and anxiety. There are currently no effective treatments for severe CVI of the deep vein system caused by valvular incompetence. Estimates indicate that CVI costs the U.S. healthcare system in excess of $4 billion each year.

About enVVeno Medical Corporation

enVVeno Medical (NASDAQ:NVNO) is an Irvine, California-based, late clinical-stage medical device Company focused on the advancement of innovative bioprosthetic (tissue-based) solutions to improve the standard of care for the treatment of venous disease. The Company's lead product, the VenoValve®, is a first-in-class surgical replacement venous valve being developed for the treatment of deep venous Chronic Venous Insufficiency (CVI). The Company is also developing a non-surgical, transcatheter based replacement venous valve for the treatment of deep venous CVI called enVVe®. CVI occurs when valves inside of the veins of the leg become damaged, resulting in the backwards flow of blood (reflux), blood pooling in the lower leg, increased pressure in the veins of the leg (venous hypertension) and in severe cases, venous ulcers that are difficult to heal and become chronic. Both the VenoValve and enVVe are designed to act as one-way valves, to help assist in propelling blood up the leg, and back to the heart and lungs. The VenoValve is currently being evaluated in the SAVVE U.S. pivotal study and the Company is currently performing the final testing necessary to seek approval for the pivotal trial for enVVe.
