Richland WA, Jan. 11, 2023 (GLOBE NEWSWIRE) -- Vivos Inc. (OTCQB: RDGL), Vivos Inc announced today that the company filed a utility patent application on a range of particles for precision radionuclide therapy as a follow-up to its provisional patent filed on 1/15/2022. This patent was filed in the USA and internationally via the Patent Cooperation Treaty, PCT. This includes Canada, the European Union, Japan, Australia, Brazil, China, India, South Korea, and the Russian Eurasian (Russia, Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan).

Dr. Mike Korenko stated, “We are convinced precision radionuclide therapy will become increasingly important for future cancer therapy in animals and humans. We will remain focused on IsoPet/RadioGel Yttrium-90 beta therapy, which we believe is the best beta emitter; however, we leveraged our hydrogel utility patent to incorporate other promising isotopes and compounds for a range of future applications. This includes gamma and alpha particle emitters. This will place us in a strong future intellectual property position.”

About Vivos Inc. (OTCQB: RDGL)

Vivos Inc. has developed a Yttrium-90-based injectable Precision Radionuclide Therapy brachytherapy device to treat tumors in animals (IsoPet®) and humans (RadioGel™). Using the company’s proprietary hydrogel technology, Brachytherapy uses highly localized radiation to destroy cancerous tumors by placing a radioactive isotope directly inside the treatment area. 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 the safe delivery of higher doses needed for treating 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 a 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 outpatient procedure, and the patient may return home without subsequent concern for radiation dose to family members.

University veterinary hospitals use the IsoPet® Solutions division to demonstrate animal cancers’ safety and therapeutic effectiveness. Testing on feline sarcoma at 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 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 to avoid confusion and cross-use.
