MELBOURNE, Australia, Sept. 28, 2020 /PRNewswire/ -- A novel nasal treatment developed to boost the natural human immune system to fight common colds and flu, has proved remarkably successful in reducing COVID-19 viral replication test results, released today, reveal.

The novel product, INNA-051, being developed by Australian biotech company, Ena Respiratory, reduced viral replication by up to 96 percent in a gold-standard animal study led by Public Health England's (PHE) Deputy Director, Professor Miles Carroll and published today on biomedical pre-publication research site, medRxiv.

The INNA-051 compound works by stimulating the innate immune system, the first line of defence against the invasion of pathogens into the body.

The study provides evidence that INNA-051 can be used as a stand-alone method of antiviral preventative therapy, complementary to vaccine programs.  Read more >>
