Medigus: Polyrizon's innovative proprietary technology found effective against coronavirus in a pre-clinical study


Polyrizon’s formulations demonstrated high efficacy by preventing coronavirus from interacting with epithelial host cells and by inhibiting cells' death

OMER, Israel, July 23, 2021 (GLOBE NEWSWIRE) -- Medigus Ltd. (Nasdaq: MDGS), a technology company engaged in advanced medical solutions, innovative internet technologies and electric vehicle and charging solutions, today announced that Polyrizon Ltd., a privately held company (which Medigus owns 33.24% of its share capital) engaged in developing highly differentiated biological gels for the purpose of protecting patients against biological threats and external pathogens, reported pre-clinical data from its previously announced pre-clinical study showing that its proprietary technology has the potential to reduce the risk of an infection with Human coronavirus and may also prevent COVID-19.

Polyrizon tested a few prototypes of its lead platform against Covid-19 viruses. In these studies, the products demonstrated high efficacy over the controlled groups by preventing coronavirus from effecting epithelial host cells and by inhibiting cells' death. In addition, the product shows a very good safety profile in a cell toxicity studies, together with broad spectrum activity against different viruses and other biological threats.

These pre-clinical data highlight the effect that Polyrizon’s product can provide against SARS-CoV-2 and a variety of different respiratory viruses such as cold and flu.
