A collaborative study led by the Monash Biomedicine Discovery Institute (BDI) with the Peter Doherty Institute of Infection and Immunity (Doherty Institute), a joint venture of the University of Melbourne and Royal Melbourne Hospital, has shown that an anti-parasitic drug already available around the world kills the virus within 48 hours.

The Monash Biomedicine Discovery Institute’s Dr. Kylie Wagstaff, who led the study, said the scientists showed that the drug, Ivermectin, stopped the SARS-CoV-2 virus growing in cell culture within 48 hours.

“We found that even a single dose could essentially remove all viral RNA by 48 hours and that even at 24 hours there was a really significant reduction in it,” Dr. Wagstaff said.

Ivermectin is an FDA-approved anti-parasitic drug that has also been shown to be effective in vitro against a broad range of viruses including HIV, Dengue, Influenza and Zika virus.

Dr. Wagstaff cautioned that the tests conducted in the study were in vitro and that trials needed to be carried out in people.

“Ivermectin is very widely used and seen as a safe drug. We need to figure out now whether the dosage you can use it at in humans will be effective – that’s the next step,” Dr. Wagstaff said.

“In times when we’re having a global pandemic and there isn’t an approved treatment, if we had a compound that was already available around the world then that might help people sooner. Realistically it’s going to be a while before a vaccine is broadly available.

Although the mechanism by which Ivermectin works on the virus is not known, it is likely, based on its action in other viruses, that it works to stop the virus ‘dampening down’ the host cells’ ability to clear it, Dr. Wagstaff said.

Royal Melbourne Hospital’s Dr. Leon Caly, a Senior Medical Scientist at the Victorian Infectious Diseases Reference Laboratory (VIDRL) at the Doherty Institute where the experiments with live coronavirus were conducted, is the study’s first author.

“As the virologist who was part of the team who were first to isolate and share SARS-COV2 outside of China in January 2020, I am excited about the prospect of Ivermectin being used as a potential drug against COVID-19,”  Dr. Caly said.

Dr. Wagstaff made a previous breakthrough finding on Ivermectin in 2012 when she identified the drug and its antiviral activity with Monash Biomedicine Discovery Institute’s Professor David Jans, also an author on this paper. Professor Jans and his team have been researching Ivermectin for more than 10 years with different viruses.

Dr. Wagstaff and Professor Jans started investigating whether it worked on the SARS-CoV-2 virus as soon as the pandemic was known to have started.

The use of Ivermectin to combat COVID-19 would depend on the results of further pre-clinical testing and ultimately clinical trials, with funding urgently required to keep progressing the work, Dr. Wagstaff said.

Ivermectin Information From Wikipedia

Ivermectin is a medication used to treat many types of parasite infestations. This includes head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis, and lymphatic filariasis.

Ivermectin was discovered in 1975 and came into medical use in 1981. It is on the World Health Organization’s List of Essential Medicines, the safest and most effective medicines needed in a health system. The wholesale cost in the developing world for the tablets is about US $0.12 for a course of treatment. In the United States, the costs is less than US$50. In other animals, it is used to prevent and treat heartworm among other diseases.
