IRVINE, CA / / June 6, 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 interim two-year follow-up data on 42 subjects from the 75 person VenoValve U.S. pivotal trial will be presented today by lead enroller Dr. Cassius Iyad Ochoa Chaar, at the Society for Vascular Surgery (SVS) 2025 Vascular Annual Meeting (VAM25) being held June 4-7, 2025 in New Orleans, LA. Additionally, the Company announced it will host a live webcast to discuss these interim results today, Friday, June 6th at 11:20 AM ET / 10:20 AM CT (details below).
Key interim two-year follow-up data being presented at VAM25 include:
83.3% of subjects (n=35/42) maintained a clinically meaningful benefit, defined as an improvement of 3 or more points in the revised Venous Clinical Severity Score (rVCSS).
9.1 point average rVCSS improvement among the responder cohort.
A median 74% improvement in leg pain, as measured by the Visual Analog Scale (VAS).
Wound healing outcomes in 17 subjects with 25 ulcers showed that 60% of ulcers healed completely, 24% decreased in size, and 16% increased in size.
Patient-reported outcomes also demonstrated sustained improvements across all venous specific QoL indicators (VEINES-QoL/Sym).
Among the subjects (n=30), a 100% valve patency rate.
All values were calculated comparing each patient's baseline levels to the reported values at the patient's 24-month visit. The Revised Venous Clinical Severity Score (rVCSS) is a clinically validated scoring system used to track the progression or regression of venous diseases.
"These interim two-year follow-up data demonstrate substantial and sustained improvement across all effectiveness endpoints at two years. This is extremely encouraging, especially when you consider that all the patients enrolled in the study had severe CVI and failed all other treatment options," said Robert Berman, enVVeno Medical's Chief Executive Officer. "Despite attempts over many decades, nobody has been able to create an effective treatment for severe CVI caused by malfunctioning valves in the deep veins of the leg. The VenoValve has the potential to change the treatment paradigm for deep venous CVI, both for the millions of patients suffering from severe CVI and the thousands of vascular surgeons who have been waiting for an effective treatment option."
Dr. Cassius Iyad Ochoa Chaar, who is the Associate Professor of Surgery, Division of Vascular Surgery and Endovascular Therapy, Yale School of Medicine, will present the abstract titled, "Patients with Deep Venous Reflux Continue to Experience Clinical Improvement 2-year after Implantation of the VenoValve" today at VAM 2025.
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 has submitted a pre-market authorization (PMA) application for the VenoValve to the U.S. Food and Drug Administration (FDA), with a decision anticipated in the second half of 2025.
Webcast Details
The Company will host a webcast presentation to discuss the results for investors, analysts and other interested parties today, June 6, 2025, at 11:20 AM ET / 10:20 AM CT. Joining enVVeno management for the event will be Dr. Chaar. The live webcast will be accessible on the Events page of the enVVeno website, envveno.com, and will be archived for 90 days.
About CVI
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.

Egg recall over salmonella warning spans across nine states
Almost two million eggs have been recalled in the United States over concerns of salmonella contamination. The recall, announced on Friday by the U.S. Food and Drug Administration, affects products distributed in nine states and is associated with various grocery store chains. According to the FDA, California-based August Egg Company of Hilmar is recalling 1,700,000 dozen brown cage-free and brown certified organic eggs due to potential contamination. The eggs were distributed from February 3 through May 15, with sell-by dates from March 4 to June 4, within California and Nevada. Products were distributed at locations including Save Mart, FoodMaxx, Lucky, Smart & Final, Safeway, Raleys, Food 4 Less, and Ralphs. Eggs were also distributed from February 3 through May 6 with sell-by dates from March 4 to June 19 to Walmart locations in California, Washington, Nevada, Arizona, Wyoming, New Mexico, Nebraska, Indiana, and Illinois. The recalled eggs will have the plant code number P-6562 or CA5330 printed on the carton or package, with Julian Dates between 32 and 126. The recalled retail eggs will be in fiber or plastic cartons, with the above codes printed on one side of the carton. Salmonella can cause serious and sometimes fatal infections in young children, the frail or elderly, and others with weakened immune systems, according to the FDA. Healthy persons infected with Salmonella often experience fever, nausea, vomiting, abdominal pain, and even bloody diarrhea. In rare circumstances, infection with Salmonella can result in more severe illnesses. A statement from August Egg Company read: 'It is important to know that when our processing plant identified this concern, we immediately began diverting all eggs from the plant to an egg-breaking facility, which pasteurizes the eggs and kills any pathogens. 'August Egg Company's internal food safety team is also conducting its own stringent review to identify what measures can be established to prevent this situation from recurring. 'We are committed to addressing this matter fully and to implementing all necessary corrective actions to ensure this does not happen again.'

How thousands of unreviewed ingredients got into our food — and what FDA can do about it
At least 1,000 ingredients in food products on our grocery store shelves have never been checked for safety by the Food and Drug Administration. Dozens have raised serious safety concerns among experts. How did the FDA allow this? The answer can be found in the agency's lax interpretation of a little-known legal designation that lets companies decide for themselves if ingredients in their products are safe. Fortunately, there are steps the agency can take right now to stem the flow of potentially unsafe ingredients into our food supply. Environmental Defense Fund outlined these steps in a letter we recently sent to the agency, but first let's take a closer look at how we got here. 'Generally Recognized as Safe' is a designation Congress created in 1958 to allow commonly used food ingredients to bypass the FDA's pre-market safety review process. It was meant for food substances — such as oils, vinegar, baking soda and common spices — that were widely considered safe due to their long history of everyday use. Since 1958, this status has been coopted to cover a universe of foods that extends far beyond its original intent. According to FDA regulations, a chemical can receive the designation if experts widely agree that scientific evidence shows its use to be safe. But because 'Generally Recognized as Safe' wasn't meant for newer ingredients, Congress allowed ingredients so designated to skip the FDA's premarket approval process — despite requiring similar evidence for other additives. Under the agency's current interpretation, companies can designate the use of a substance as safe and take products with that substance to market without informing the FDA or the public of its decision. While companies may voluntarily submit a notice to FDA offering safety evidence, they are not required to — and often don't. Our organization estimated that manufacturers have notified FDA of fewer than half of the ingredients they market as safe under the 'Generally Recognized' standard. Companies that do bother to submit a notice to the FDA are free to withdraw it at any point and take their product to market, provided they can cite evidence of its safe use. But this 'evidence' is often far from independent. Companies can, and often do, enlist their own employees or handpicked consultants to conduct their safety assessments. The result is a process riddled with conflicts of interest that lets unsafe foods into Americans' homes. We analyzed 'Generally Recognized as Safe' notices received by the FDA, obtained via a Freedom of Information request, and found that of the 1,163 submitted by companies between 1997 and April 2024, 192 were later withdrawn, with safety concerns cited in at least a dozen cases. We also identified 31 ingredients that companies have advertised to be recognized as safe, such as in press releases, trade publications and on their own websites (see the Appendix of our letter). However, we were unable to find the scientific evidence required under this standard to demonstrate these ingredients are commonly regarded as safe among experts. This raises red flags that FDA should be taking seriously. Although a comprehensive fix to the 'Generally Recognized' standard will require legislation from Congress, there are significant steps the FDA can take right away to ensure a more rigorous determination process that better protects Americans' health. Starting today, the FDA can use existing authority to remove safe designations from ingredients it deems unsafe and take them off the market. It can also notify manufacturers, importers, distributors and retailers that the substance is no longer recognized as safe. In addition, the FDA can enforce the requirement that companies base safety designations on publicly available data. Although this won't curtail companies' ability to self-declare substances as safe, it will require those who do to be transparent in citing their evidence. Third, the FDA can enforce the requirement that safety assessments consider vital health information such as a substance's dietary sources, potential cancer risks and the cumulative health effects of similar substances. Finally, the FDA can make companies revise and resubmit their data for review when they submit 'Generally Recognized as Safe' notices that fail to comply with the criteria. The 'Generally Recognized as Safe' designation is far from a perfect system, but it can work better if it is interpreted and enforced more comprehensively. If the FDA is serious about protecting public health, it should start by fully exercising the tools already at its disposal.

Psychedelics as potential mental health treatment are explored by Trump administration
The Trump administration has expressed interest in exploring psychedelics for their potential in treating PTSD and other debilitating mental health issues, various officials have shared. "The Department shares the goal of ensuring that all Americans — especially our nation's veterans — have access to safe and effective treatments for conditions such as PTSD, addiction and depression," a spokesperson for the U.S. Department of Health and Human Services (HHS), run by Sec. Robert J. Kennedy Jr., said in a statement provided to Fox News Digital. "Secretary Kennedy is committed to applying rigorous, evidence-based science to research efforts aimed at addressing these serious health challenges." Fda Approves First Ai Tool To Predict Breast Cancer Risk In recent years, researchers have been actively investigating the potential of psychedelics, such as MDMA and psilocybin ("magic mushrooms") to treat mental health disorders. MDMA is not approved for clinical use by the U.S. Food and Drug Administration (FDA), but can be studied in clinical settings. Read On The Fox News App Psilocybin is listed as a Schedule I substance under the Controlled Substances Act, which means it has "a high potential for abuse, [is not] currently accepted for medical use in treatment in the United States, and [has] a lack of accepted safety for use under medical supervision." Psilocybin-assisted therapy, however, is legal in Oregon, Colorado and New Mexico. Psychedelic medicines are "showing real promise," according to Dr. Luke Twelves, general practitioner and vice president of medical for Lindus Health in London. Clinical trials have found such treatments safe and effective for patients battling serious mental health issues, according to Twelves. Common Supplements And Medications Could Cause Liver Damage, Studies Show "Take psilocybin, for example — it's demonstrating remarkable results for severe depression that hasn't responded to other medications," he told Fox News Digital. "MDMA is showing similar breakthroughs for PTSD treatment." Clinical trials are also investigating how psychedelics could help with end-of-life anxiety, addiction, eating disorders, chronic pain and OCD, he added. Researchers have faced challenges in terms of regulatory hurdles and proper placebo controls, Twelves said. "Given that these treatments could transform [the] lives of people suffering from conditions where nothing else has worked effectively, it's crucial that we complete this research properly," he said. "The goal is to bring safe, proven psychedelic therapies to the patients who need them most." At President Trump's May 1 cabinet meeting, Department of Veterans Affairs Secretary Doug Collins said that "we're opening up the possibility of psychedelic treatment." Retired Army Sergeant Jonathan Lubecki recently told Fox News' Alexandria Hoff that MDMA stopped his PTSD while he was participating in a clinical trial. "[I] took my first dose of MDMA. I've only taken it three times as part of the clinical trial, haven't taken it since, and haven't found the need to take it since, because I haven't had PTSD," he said. Peter Kasperowicz, Department of Veterans Affairs press secretary, told Fox News Digital the department is safely exploring all avenues that promote the health of veterans. Fallujah Vet Turns Medal Of Heroism Into A Healing Mission For Fellow Warriors With Service Dogs Program "Preliminary findings have produced positive results on psychedelic-assisted therapies for treating mental health conditions," he said. The VA is currently running 11 clinical trials in various phases, with a total of some 800 veterans expected to participate. "The goal of these trials is to determine whether compounds such as MDMA and psilocybin can treat veterans with post-traumatic stress disorder, treatment-resistant depressive disorder, major depressive disorder and potentially other mental health conditions," said Kasperowicz. An MDMA study published in the Jan. 2025 issue of The American Journal of Psychiatry found that the substance is "unlike classical psychedelics." The study noted, "MDMA allows the individual to maintain intact ego functioning and a greater degree of cognitive and perceptual lucidity while still experiencing a prosocial altered state of consciousness that facilitates deeply emotional therapeutic breakthroughs." Click Here To Sign Up For Our Health Newsletter The researchers concluded that MDMA showed "enhanced levels of trust, empathy, self-compassion and a 'window of tolerance'" that traditional psychotherapy lacks. Doug Drysdale, CEO of the Canadian pharmaceutical company Cybin, told Fox News Digital that "the time is now to address the mental health crisis." He said it is "gratifying" that administration officials value the potential benefits of looking into alternative mental health treatments. Cybin is currently in phase 3 of a study of CYB003, a type of psilocybin that has been granted breakthrough therapy designation by the FDA as an additional treatment for major depressive disorder (MDD). "In Cybin's completed Phase 2 MDD study, long-term efficacy results showed that 71% of participants were in remission from depression, and 100% of participants responded to treatment at 12 months after just two 16 mg doses of CYB003," said Drysdale. Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Center and Fox News' senior medical analyst, previously interviewed two of the country's top researchers on psychedelics — Dr. Rachel Yehuda, founder and director of the Center for Psychedelic Psychotherapy and Trauma Research at Mt. Sinai in New York, and Dr. Charles Marmar, director of the PTSD research program at NYU Langone. "They agree there is therapeutic potential if very carefully studied under very strict medical guidance, but there is a huge downside in terms of unregulated recreational uses," Siegel told Fox News Digital at the time. "Both doctors see likely therapeutic value to psychedelics if carefully managed by medical experts," Siegel added. Ryan Moss, chief science officer at Filament Health, a clinical-stage natural psychedelic drug development company in Canada, emphasized it's important to administer psychedelics in a safe setting when treating mental health conditions. For more Health articles, visit "Psychedelic experiences can sometimes feature anxiety, hallucinations and paranoia," Moss previously told Fox News Digital. "Some patients using traditional psychedelics have reported experiencing adverse cardiovascular events during clinical trials." To mitigate these risks, Moss recommended clinical trial participants receive thorough preparation and monitoring by trained professionals during sessions.
