Vivos Inc Achieves Important Radiogel™ Development Milestones

Richland WA, June 24, 2020 (GLOBE NEWSWIRE) -- Vivos Inc. (OTCQB: RDGL), Vivos announced today significant progress in its efforts to advance RadioGel^™ for human therapy. Animal testing at the University of Missouri was completed in 2019. Since then we have been focusing on completing the Radiogel^™ Quality Management System (“QMS”). Our QMS validates that the pedigree of all future testing complies with the strict FDA guidelines. This week we initiated the biocompatibility testing contract as part of the previously defined pre-clinical testing. We are targeting to present our interim results to the FDA in a pre-submission meeting this year. This will set the stage for submittal of the Investigational Device Exemption (IDE). FDA approval of the IDE is required to begin clinical trials in humans. We believe that approval of the IDE will significantly enhance the potential partnering and licensing opportunities for Radiogel^™.

Dr. Mike Korenko stated, “completion of our QMS and the initiation of biocompatibility testing are important milestones for Radiogel^™ and are critical steps in our continuing efforts to bring Radiogel^™ to the human market. Additionally, we continue to focus on marketing and product development in animal therapy using our companion product, Isopet^®.”

About Vivos Inc. (OTCQB: RDGL)

Vivos Inc. has developed an Yttrium-90 based injectable 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 particles 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 using 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.
