Spain's PharmaMar said on Tuesday trials made in vitro and on animals showed its Plitidepsin drug had positive antiviral effects on the variants of COVID-19, including Omicron.
The results of Phase I trials have shown the drug, also known as Aplidin, had a powerful antiviral activity against all the variants in vitro and distribution into the lungs of animals tested, resulting in a 99% reduction of viral load in the lungs, the company said.
The results of the trials were released in a paper published in the scientific journal Life Science Alliance, PharmaMar said.
