enVVeno Medical Corporation reported a net loss of $3,849 thousand for the quarter ended March 31, 2026, narrowing from $4,503 thousand a year earlier as operating expenses fell. Research and development expenses declined to $2,111 thousand and selling, general and administrative costs decreased to $1,951 thousand, reflecting lower VenoValve study spending and reduced overhead.
The company held $24.9 million of cash and investments and $23.3 million of working capital as of March 31, 2026, and expects this to fund operations into the third quarter of 2027, even as quarterly cash burn is projected to rise to between $4 million and $5 million in 2026.
Strategically, enVVeno is pivoting from its surgical VenoValve, which received a non-approvable FDA letter in 2025, to the minimally invasive enVVe System. On April 29, 2026, the FDA approved its Investigational Device Exemption, allowing the pivotal TAVVE study of the transcatheter enVVe valve in severe deep Chronic Venous Insufficiency to begin, with up to 230 patients enrolled across as many as 40 U.S. sites.
enVVeno Medical Corporation reported that the FDA approved its Investigational Device Exemption (IDE) application, allowing the Company to begin the Transcatheter Venous Valve Endoprosthesis (TAVVE®) pivotal study of its minimally invasive enVVe® replacement venous valve for severe deep Chronic Venous Insufficiency (CVI).
The study will start with 10 patients whose 30‑day safety data will be reviewed by the FDA, followed by a second stage enrolling 220 patients, including 165 treated with enVVe and 55 controls receiving standard care, at up to 40 U.S. clinical sites. One year after the 220th second‑stage patient is enrolled, the Company would be eligible to file for FDA post‑marketing approval.
enVVeno also disclosed that as of March 31, 2026, it had approximately $25 million in cash and investments, which it expects will fund operations into the third quarter of 2027.
enVVeno Medical Corporation files its annual report detailing a major strategic pivot after its surgically implanted VenoValve received a not-approvable letter from the FDA in August 2025 and a subsequent appeal was denied. The company is now concentrating on the enVVe System, a first-in-class, non-surgical, transcatheter replacement venous valve for severe chronic venous insufficiency, and has completed pre-clinical testing while beginning FDA discussions for a pivotal trial expected to start in 2026. enVVeno highlights that it has no product revenue, has incurred significant losses since inception, and may never achieve profitability without successful regulatory approval and commercialization of enVVe or future devices. The filing emphasizes substantial clinical, regulatory, manufacturing, reimbursement and financing risks, reliance on a small supplier base for porcine tissue and components, and the need for additional capital to continue development. As of June 30, 2025, non-affiliate common equity market value was $76.1 million, and as of March 24, 2026, there were 655,521 shares of common stock outstanding and 33 full-time employees.
