NEWS -- Vivos Inc Files a New Patent on the Hydrogel Component of IsoPet®/RadioGel™

Richland WA, Sept. 14, 2022 (GLOBE NEWSWIRE) -- Vivos Inc. (OTCQB: RDGL), Vivos Inc announced today that they filed a patent application on their hydrogel component of IsoPet/RadioGel in the USA (16309: 17/943,311) and internationally (16389: PCT/US22/43274) under The Patent Cooperation Treaty (PCT).

Over the last eighteen months our team has worked with polymer contracting experts to optimize our hydrogel component. Our objectives were to maximize production output, to refine our specifications to yield the optimum gelation and resorption characteristics, to demonstrate reproducibility and to ensure that any residual solvents were minor and well below the FDA specifications limits for human therapy. As part of our improved Quality Management System, we are confident that the new Vivos Inc Standard Operating Procedure for Polymer Production will meet GMP/FDA Specifications.

Dr. Mike Korenko stated, “This was a substantial effort that revealed novel production insights that are not obvious and therefore patentable. As part of this process, we just filed a patent application on the hydrogel component, while keeping the production refinements as important proprietary intellectual property.

“This filing was on the heels of another milestone for Vivos, as the US Patent office recently gave us the Notice of Allowance for our patent to produce our yttrium phosphate microparticles, US Patent Application Serial No: 16-459,466. Our new particle patent and our hydrogel component patent filing are significant achievements consistent with our objective for strong intellectual property protection on both of our key components. We will continue to improve our processes to enhance our intellectual property as a fundamental business strategy as we continue our progress in establishing Radiogel™ and Isopet® as a next generation treatment option using Injectable Precision Radionuclide Therapy.”

About Vivos Inc. (OTCQB: RDGL)

Vivos Inc. has developed an Yttrium-90 based injectable Precision Radionuclide Therapy brachytherapy device, for the treatment of tumors in animals (IsoPet®) and in humans (RadioGel™). Brachytherapy uses highly localized radiation to destroy cancerous tumors by placing a radioactive isotope directly inside the treatment area using the company’s proprietary hydrogel technology. The injection delivers therapeutic radiation from within the tumor without the entrance skin dose and associated side effects of treatment that characterize external-beam radiation therapy. This feature allows safe delivery of higher doses needed for treating both non-resectable and radiation-resistant cancers.

Radiogel™ is a hydrogel liquid containing tiny yttrium-90 phosphate microparticles that may be administered directly into a tumor. The hydrogel is an yttrium-90 carrier at room temperature that gels within the tumor interstitial spaces after injection to keep the radiation sources safely in place. The short-range beta radiation from yttrium-90 localizes the dose within the treatment area so that normal organs and tissues are not adversely affected.

Radiogel™ also has a short half-life – delivering more than 90% of its therapeutic radiation within 10 days. This compares favorably to other available treatment options requiring up to six weeks or more to deliver a full course of radiation therapy. Therapy can be safely administered as an out-patient procedure and the patient may return home without subsequent concern for radiation dose to family members.

The Isopet® Solutions division is used university veterinary hospitals to demonstrate the safety and therapeutic effectiveness for different animal cancers. Testing on feline sarcoma at the Washington State University was completed in 2018 and testing on canine soft tissue sarcomas at the University of Missouri was completed in 2019.

In 2018 the Company obtained confirmation from the FDA Center for Veterinary Medicine that Isopet® is classified as a medical device according to its intended use and means by which it achieves its intended purpose. The FDA also reviewed the product labeling which included canine and feline sarcomas as the initial indications for use. The FDA does not require pre-market approval for veterinary devices so no additional approval was required for treating skin cancer, which is the largest market sector. Following the demonstration phase, Vivos is able to generate revenue through the sale of Isopet® to University animal hospitals and private veterinary clinics.

Isopet® for treating animals uses the same technology as RadioGel™ for treating humans. The Food and Drug Administration advised using different product names in order to avoid confusion and cross-use.
