Repurposed drugs may have a speedier path to clinical use because they have already been shown to be safe in people. A study publishing May 19in the open access journalPLOS Pathogensby Sandrine Belouzard and Jean Dubuisson at Pasteur Institute, Lille, France and colleagues suggests clofoctol may be an effective treatment for SARS-CoV-2 infections in mice.
While COVID-19 vaccines reduce hospitalizations and death, they do not control virus transmission, and affordable, effective therapies are needed. Previous attempts to repurpose medicines to treat COVID-19 patients have been unsuccessful. In order to identify potential antiviral therapies effective against COVID-19, authors accessed the Apteeus drug library, a collection of 1,942 approved drugs to identify molecules that exhibit antiviral activity against SARS-CoV-2. The authors selected clofoctol based on its antiviral potency and tested their hypothesis by testing its effects in SARS-CoV-2-infected mice.
The researchers found that transgenic mice treated with clofoctol had a decreased viral load, reduced inflammatory gene expression, and lowered pulmonary pathology. Future studies are needed to further understand the drug's therapeutic potential in SARS-CoV-2 patients as the study was limited by the physiological differences between humans and mice. Additionally, the mice were sacrificed only two days after treatment, so longer-term effects remain unknown.
According to the authors, "The antiviral and anti-inflammatory properties of clofoctol, associated with its safety profile and unique pharmacokinetics make a strong case for proposing clofoctol as an affordable therapeutic candidate for the treatment of COVID-19 patients. Finally, the relatively low cost of this drug suggests that it is a potential clinical option for treatment of COVID-19 patients in resource-poor settings."
"Antivirals targeting SARS-CoV-2 are sorely needed," adds Dubuisson. "In this study, we screened a library of drug compounds and identified clofoctol as an antiviral against SARS-CoV-2. We further demonstrated that, in vivo, this compound reduces inflammatory gene expression and lowers pulmonary pathology and decreases viral load."
