Following the initial safety data review by the FDA, the SAVVE study is cleared to continue without modification or interruption

The Company currently has 33 patients enrolled in the study and expects to be fully enrolled by the end of Q2 of 2023

With $42.7 million of cash and investments reported at the end of Q3 of 2022, the Company has sufficient cash to sustain operations through the end of 2024, including release of SAVVE topline pivotal trial data

IRVINE, CA / ACCESSWIRE / November 7, 2022 / 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 the Company has successfully passed a preliminary safety review by the U.S. Food and Drug Administration (FDA) for the first twenty (20) patients enrolled in the ongoing SAVVE (Surgical Anti-reflux Venous Valve Endoprosthesis) U.S. pivotal study for the VenoValve.

The FDA had requested that enVVeno submit preliminary safety data at thirty (30) days post VenoValve implantation for the first twenty (20) patients enrolled in the study. The preliminary safety data submitted by the Company included one (1) device related (mild) and two (2) procedure related (moderate) adverse events. After review by the FDA, the study was cleared to continue without modification or interruption.

The Company currently has thirty-three (33) patients enrolled in the trial and based upon the current pace of enrollment, expects to be fully enrolled by the end of the second quarter of 2023. With $42.7 million of cash and investments reported at the end of the third quarter of 2022, the Company has sufficient cash to sustain operations through the end of 2024, including past the expected release of thirty (30) day primary safety and one hundred eighty (180) day primary efficacy endpoint data from the study.

"It is not unusual for the FDA to request to closely monitor safety data for an initial group of patients in a study for a first-in-class device such as the VenoValve," said Robert Berman, enVVeno Medical's Chief Executive Officer. "We are encouraged by the safety profile of the VenoValve for this initial group of patients and are pleased that the FDA permitted the study to continue without any changes due to safety concerns."

The SAVVE Trial is a prospective, non-blinded, single arm, multi-center study of 75 CVI patients. The trial's primary safety endpoint is based on the number of major adverse events (MAEs) at 30 days post implantation. MAEs are defined as mortality, deep wound infection, major bleeding, ipsilateral deep vein thrombosis or pulmonary embolism.

The VenoValve® is surgical replacement venous valve that is being evaluated as a potential treatment for deep venous CVI. The VenoValve is intended to restore proper directional blood flow for patients with CVI of the deep veins of the leg. CVI occurs when the natural valves inside of the veins fail, causing blood to flow in the wrong direction (reflux), and creating increased pressure inside of the veins of the leg (venous hypertension).

CVI can cause the leg to swell, and blood vessels to break, resulting in discoloration, pain, and the breakdown of the skin leading to venous ulcers (open sores) which are difficult to heal. Patients with severe CVI have limited mobility and often experience difficulty standing, walking, and completing everyday tasks. The Company estimates that approximately 2.5 million people in the U.S. suffer from the debilitating impacts of severe deep venous CVI who would be candidates for the VenoValve.

Patients suffering from lower leg swelling, pain, non-healing leg sores, enlarged veins, and/or brownish or blueish skin discoloration - who may also have leg pain when standing or walking - may be candidates for the SAVVE trial.

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 waiting for regulatory approval to begin the TAVVE first-in-human trial for enVVe.
