Research into a new drug that primes the immune system in the respiratory tract and is in development for COVID-19 shows it is also effective against rhinovirus.
Rhinovirus is the most common respiratory virus, the main cause of the common cold and is responsible for exacerbations of chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease. In a study recently published in the European Respiratory Journal, the drug, known as INNA-X, is shown to be effective in a pre-clinical infection model and in human airway cells.
Treatment with INNA-X prior to infection with rhinovirus significantly reduced viral load and inhibited harmful inflammation.
University of Newcastle and Hunter Medical Research Institute (HMRI) researcher Associate Professor Nathan Bartlett, who led the study, said INNA-X showed great promise as a new way to protect people from diseases caused by common respiratory viruses such as rhinovirus. These diseases range from the common cold to potentially life-threatening exacerbations of chronic respiratory diseases, which cost the global economy billions of dollars each year.
“Consistent with what we have reported for other respiratory viruses including SARS-CoV-2 (the virus that causes COVID-19), INNA-X treatment prior to infection reduced the level of virus in the respiratory tract,” Associate Professor Bartlett said.
“We have also examined the effect of INNA-X in airway cells from patients with asthma which we know have a less effective anti-viral immune response and found that INNA-X treatment was effective providing a rationale for the use of INNA-X in at risk populations.”
INNA-X is developed by the Australian biotech company Ena Respiratory and works by stimulating the innate immune system in the airways, the first line of defense against the invasion of respiratory viruses into the body. This immune priming makes it much more difficult for viruses such as rhinoviruses to take hold, cause serious symptoms and spread.
INNA-X has been also shown to be highly effective at reducing virus shedding of SARS-CoV-2 and human trials of Ena Respiratory’s clinical candidate INNA-051 will begin in Australia in the coming weeks.
“If found protective, this could be used by at risk populations including elderly or asthma patients, to reduce the severity of rhinovirus, COVID-19 and other respiratory viruses’ infections in conjunction with vaccine approaches,” Associate Professor Bartlett said.

Here we go again, great and wonderful solutions…
Ooh, ooh, just like seawater or colloidal silver! Who’da thunk?!
How does it work? I realize that would be committing an Act of Journalism to let us know, but as it stands this article is nonsense.
I read the article with no bias and learned that it primes the immune system against viral infection. This is nothing new or incomprehensible unless of course, one is not of sufficient intelligence to comprehend what they have just read. I try to practice the same principle by way of nutrition like broccoli is good for the lungs and dairy tends to mucus one up. Anyhoo yahoo,smarten up or shut up.
Yes, but HOW does it do this magical trick? You and your gullible ilk never get below the pop veneer. You can be told anything and if it makes you happy you can believe it.
And your mother wears army boots.
“Researchers were able to use cells from human donors and re-grow the structure of the airway surface, the epithelium, to recreate the first line of defense against respiratory viruses. This model of the human airway was key to researchers showing that INNA-X can directly activate your airway epithelium so that it is better prepared to repel viruses and protect you from disease”
This is how it works, the citation is from the text below the picture. Obviously its a drug, so, as its under development still, no exact details yet revealed about the ingredients. Why would they donor the results of the research for free? Hang on a minute.
