(OTCQB: RDGL), a company pioneering Precision Radionuclide Therapy™ (PRnT) with its innovative RadioGel® technology, today announced the submission of its Early Feasibility IDE application to the FDA. This milestone represents a significant advancement in the Company’s regulatory pathway and builds directly on the substantial progress detailed in its February 10, 2026 update. RadioGel® delivers precise, localized beta radiation to solid tumors while minimizing exposure to surrounding healthy tissue. This targeted approach offers significant potential as a new treatment option for patients with difficult-to-treat tumors, including those with metastatic disease. The Early Feasibility IDE application, developed with expert regulatory guidance from our experienced IDE approval specialists, reflects Vivos’ iterative engagement with the FDA. It includes strengthened technical and manufacturing data confirming precise delivery and highly localized retention, additional clinical insights from the ongoing international human trial, updated preclinical evidence addressing prior Agency questions, and compelling real-world safety data from over 200 IsoPet® veterinary patients across a wide range of tumor types with a favorable safety profile. This refined submission underscores the Company’s commitment to a thorough, data-driven regulatory process and positions RadioGel® for advancement into early human feasibility studies. The Company expects to receive FDA feedback or decision within the standard 30-day review period. As interest in Vivos’ product portfolio and market potential continues to grow, the Company recently participated in the SNMMI 2026 Annual Meeting in Los Angeles (May 30–June 2). During the conference, Vivos engaged with numerous key leaders in nuclear medicine and molecular imaging, resulting in several productive discussions and valuable new contacts that further indicate the significant clinical interest in RadioGel®. “We are pleased to have reached this key regulatory milestone,” said Dr. Michael Korenko, CEO of Vivos Inc. “Building on the foundation shared earlier this year, the submission of our Early Feasibility IDE application represents meaningful progress toward bringing RadioGel® into human clinical evaluation at leading institutions. We look forward to continued collaboration with the FDA as we advance this promising therapy for patients who need better treatment options.” Vivos Inc. continues to execute its multi-tracked strategy by: 1) expanding commercial adoption of IsoPet® in veterinary oncology, 2) advancing non-U.S. clinical research and commercialization opportunities for RadioGel® through Vivos Scientific India LLP, 3) pursuing international licensing and monetization opportunities for RadioGel®, PrecisionGel®, and related technologies, and 4) progressing RadioGel® through the U.S. regulatory pathway for human use. The Company remains committed to working closely with the FDA to initiate early feasibility studies as efficiently as possible, while also advancing international growth opportunities and building on the positive momentum surrounding IsoPet®.
