Vivos Inc. receives FDA IDE approval to initiate RadioGel human study
Vivos Inc. secured FDA IDE approval to launch a first-in-human feasibility study for RadioGel, a yttrium-90-based injectable hydrogel for treating cancerous tumors. The study, set to enroll five patients at Mayo Clinic, will evaluate the therapy's safety and feasibility in non-resectable papillary thyroid carcinoma cases.

Vivos Inc. has received approval from the U.S. Food and Drug Administration (FDA) for its Investigational Device Exemption (IDE) application to begin a first-in-human feasibility study for RadioGel. This approval allows the company to initiate a US-based study using RadioGel, an innovative yttrium-90-based injectable hydrogel for the targeted treatment of cancerous tumors. The study aims to evaluate the safety and feasibility of the therapy in patients with non-resectable papillary thyroid carcinoma.
The clinical trial will be conducted at Mayo Clinic in Jacksonville, FL. The protocol is expected to initially enroll five patients, and the results will help shape subsequent pivotal trials. The FDA determined that the company provided sufficient data to support the initiation of the investigation, with the conditions of approval incorporated into the protocol for Mayo Institutional Review Board (IRB) review.
Study Details and Objectives
The feasibility study focuses on assessing the safety profile of RadioGel in human patients. Preclinical studies in veterinary patients and laboratory animals demonstrated the safety and effectiveness of Yttrium-90 RadioGel precision radionuclide therapy (PRnT) in cancer treatment. Histopathology across multiple studies confirmed no radiation-associated adverse effects in any normal organs or tissues.

Management Commentary
Brad Weeks, President of Vivos Inc., stated that the IDE approval is a major milestone validating the strength of the company's preclinical and clinical data. He emphasized that advancing RadioGel into human studies brings the company closer to delivering a precise, minimally invasive cancer therapy.
Mike Korenko, CEO of Vivos Inc., added that receiving FDA IDE approval represents the culmination of years of dedicated work. He expressed confidence in RadioGel as a breakthrough approach in precision radionuclide therapy and highlighted the partnership with Mayo Clinic as a critical step toward bringing the therapy to patients.
Strategic Focus
Vivos continues to advance its multi-track strategy, which includes expanding commercial adoption of IsoPet for veterinary oncology and advancing non-U.S. clinical research and commercialization opportunities for RadioGel. The company is also pursuing international licensing and monetization opportunities for the PrecisionGel platform while progressing RadioGel through the U.S. regulatory pathway for human cancer therapy.
