Study Confirms Viraleze Antiviral Nasal Spray Provides Protection Against SARS-CoV-2 in Challenge Model
The antiviral agent in Viraleze, SPL7013, has previously been shown to have potent antiviral and virucidal activity in multiple variants of SARS-CoV-2, including inactivation of >99.9% of the Delta variant.
Viraleze was developed for application in the nasal cavity to help reduce exposure to respiratory viruses, including SARS-CoV-2. The product is registered for sale in Europe and India , and available online in certain markets via www.viraleze.co.
Global data indicates that vaccines against COVID-19 are highly effective in preventing hospitalisation and death, but that vaccinated individuals can still become infected and shed virus. Complementary interventions, like Viraleze, could potentially be used to reduce viral load at the primary site of initial infection and could also be helpful to reduce shedding of infectious virus.
The latest study, conducted at The Scripps Research Institute , used a humanised SARS-CoV-2 mouse model recommended by the WHO. The results show that Viraleze administered nasally significantly reduced SARS-CoV-2 viral load in the respiratory tract, in the blood and in other organs in Viraleze treated animals.
The impressive protective effects of Viraleze in this SARS-CoV-2 animal model are consistent with the previously reported virucidal activity of SPL7013 , demonstrating potent antiviral activity in multiple respiratory viruses and multiple variants of SARS-CoV-2.
