IRVINE, CA / ACCESS Newswire / November 13, 2025 / enVVeno Medical Corporation (NASDAQ:NVNO) ("enVVeno" or the "Company"), a company setting new standards of care for the treatment of deep venous disease, today announced that it has received an unfavorable decision from the U.S. Food & Drug Administration ("FDA") in response to its supervisory appeal of the not-approvable letter it received on August 19, 2025 in response to its Premarket Approval (PMA) application for VenoValve®, a surgical replacement venous valve for treating severe deep chronic venous insufficiency (CVI).

We will continue to interact with the FDA on enVVe and will provide periodic updates on our progress."
