First wave of implants successfully completed with updated delivery system performing very well

Company on schedule to be in position to apply for approval for enVVe pivotal trial mid-2025

IRVINE, CA / ACCESSWIRE / October 28, 2024 / enVVeno Medical Corporation (Nasdaq:NVNO) ("enVVeno" or the "Company"), a company setting new standards of care for the treatment of venous disease, today announced the successful start to its six-month pre-clinical GLP study for enVVe, its transcatheter-delivered replacement venous valve. The first wave of implants, for the long-term subjects, was successfully completed, with the final wave for the shorter-term subjects scheduled for December. The GLP study is a prerequisite to enVVeno seeking IDE approval from the U.S. Food and Drug Administration to begin the enVVe U.S. pivotal study. The Company expects to be in a position to file for IDE approval for the enVVe pivotal trial mid-next year.

"There is no question that we could not have developed enVVe without the knowledge gained from the VenoValve over the past six years," said Robert Berman, enVVeno Medical's Chief Executive Officer. "Engineering a transcatheter replacement venous valve that will fit into a catheter of only .17 inches in diameter and that will consistently and successfully deploy once it reaches the target vein is not easy. The final adjustments that we made to the crimping and delivery systems over the past few months resulted in easy, consistent and accurate delivery of the enVVe valves in the GLP study and now we wait to confirm that the deployed enVVe valves work as well as the rest of the system."

enVVeno's lead product is the VenoValve?, a first-in-class, surgical replacement venous valve for patients suffering from severe Chronic Venous Insufficiency (CVI) caused by incompetent valves in the deep venous system. The Company estimates that there are approximately 2.5 million candidates each year in the U.S. for the VenoValve. enVVe, a next-generation, transcatheter based replacement venous valve, would appeal to an even larger market in terms of both patients and physicians.

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, 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.
