enVVeno Medical Corporation (NASDAQ:NVNO) ("enVVeno" or the "Company"), a company setting new standards of care for the treatment of venous disease, will present one year data on all subjects from the VenoValve U.S. pivotal trial today at the 51^st Annual Vascular and Endovascular, Techniques and Horizons (VEITH) Symposium in New York City. The definitive one-year data supports the application submitted earlier this week by enVVeno Medical seeking pre-market authorization (PMA) from the U.S. Food and Drug Administration (FDA) to market and sell the VenoValve in the U.S.

Among the data being presented at VEITH are:

• Eighty five percent (85%) of the subjects in the VenoValve pivotal study that reached the one-year milestone achieved a clinically meaningful benefit of a three (3) or more point improvement in revised Venous Clinical Severity Score (rVCSS).

• 7.91 point average rVCSS improvement among the rVCSS responder cohort.

• Clinical meaningful benefit was shown across all CEAP diagnostic classes of subjects (C4(b), C4(c), C5, C6) enrolled in the study.

• Ninety seven percent (97%) Target Vein Patency rate at one year.

• Hemodynamic data from the study showed a positive correlation between rVCSS improvement and systemic reflux time improvement.

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

Subjects in the VenoValve pivotal study also experienced a median reduction in pain of seventy-five percent (75%) at one year as measured by Visual Analog Scale (VAS). Additionally, among subjects with venous ulcers (CEAP C6), the median ulcer area was reduced by eighty seven percent (87%) at 12 months. Patient reported outcomes in the VenoValve pivotal study also demonstrated improvements in quality of life and disease symptoms (VEINESqol/sym, EQ5D).

"The number one concern for clinicians and where other attempts to replace venous valves have failed in the past is that they have occluded or completely blocked blood flow in the targeted refluxing vein. With a ninety seven percent (97%) Target Vein patency rate at one year, and eighty-five percent (85%) of the subjects in the VenoValve study experiencing a clinical meaningful benefit, the VenoValve should be a compelling potential option for physicians and patients with no effective treatment options from the devastating impacts of severe, deep venous CVI," said Robert Berman, enVVeno Medical's Chief Executive Officer. "We are pleased with the one-year safety and efficacy profile of the VenoValve from the pivotal study and look forward to our upcoming interactions with the FDA as they evaluate our clinical data and complete the additional steps that are a part of the PMA review process."

The Company will also update the pivotal trial safety profile of the VenoValve at VEITH, reporting Major Adverse Events (MAEs) through one year of: one (1) death (unrelated to the VenoValve), zero (0) pulmonary embolisms, twelve (12) Target Vein Thromboses, ten (10) Surgical Pocket Hematomas, four (4) Other Bleeds, and seven (7) Deep Wound Infections. Of the subjects that experienced an MAE, there was no long-term negative impact on clinical improvement as ninety-four percent (94%) of the subjects who experienced an MAE (not including the unrelated death) also experienced a clinical meaningful benefit (≥ 3 point rVCSS improvement) at one-year, compared to baseline.

Severe, deep venous Chronic Venous Insufficiency (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.

The VenoValve® is a potential first-in-class, surgical replacement venous valve for patients with severe deep venous CVI. The Company estimates that there are approximately 2.5 million potential new patients each year in the U.S. that could be candidates for the VenoValve. The Company is also developing enVVe®, a next-generation, transcatheter based replacement venous valve, that could appeal to an even larger market in terms of both patients and physicians.

The Company will host a video conference call today at 2:00 PM Eastern Time following the VEITH presentation, with the presenting Primary Investigators. To access the call visit the Events page on the Investor section of the Company's website or click here.

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.
