Vivos Inc. Reports Continued Progress in India Human Clinical Trial for RadioGel Precision Radionuclide Therapy Vivos Inc. share new developments in its ongoing human clinical trial in India for RadioGel Precision Radionuclide Therapy, an FDA-designated Breakthrough Device for the treatment of solid tumors. The latest results highlight both technical progress and growing clinical validation. This update builds upon the initial results released in February 2025, which confirmed the safety of RadioGel®? in the first five patients. As of this report, ten patients with cancerous nodes have now been successfully treated, further establishing a strong safety profile while generating promising early evidence of efficacy. Every patient in the trial has met the primary safety endpoint, confirmed through PET imaging showing precise retention of the therapeutic Yttrium-90 isotope at the injection site--with no observed adverse events. Patients continue to recover well with no complications, monitored under disciplined clinical follow-up protocols. Importantly, two of the ten patients presented with tumors in direct contact with the trachea and carotid artery, anatomical regions often considered inoperable or high-risk for radiation damage. Yet, RadioGel®? achieved successful treatment without injured adjacent critical tissues, underscoring the therapy's high Therapeutic Ratio and the core rationale behind the FDA's Breakthrough Device designation. These outcomes affirm the unique advantage of RadioGel®?: internal, highly localized beta radiation delivered directly within the tumor, sparing healthy tissue and enabling outpatient treatment with minimal post-procedure restrictions. Led by a highly experienced principal investigator in India, the clinical team has introduced new technical references to the treatment methodology, including deep-needle injection techniques, precision image guidance, and the use of saline spacers to enhance dose control and organ protection.
