It will be tested in a clinical trial next year, raising hopes that the pill could one day be taken at home to relieve unpleasant symptoms or even limit infections if there were another viral pandemic. “As far as we can tell, this is the first drug thats ever demonstrated activity across all these viral families,” says Daniel Haders , co-founder of Model Medicines, the California-based company leading its development. (we’re not making this up)

If it is approved, Haders envisages it being a pill that people could take if, for example, they have a flu-like illness but don’t know if it is influenza, covid-19, RSV or something else.

The Details

MRNA drugs could protect against almost any kind of viral infection The drug was originally developed as a breast cancer treatment named ERA-923, but it was abandoned in the early 2000s after showing little benefit in clinical trials. Now, an AI drug-discovery platform developed his colleagues has figured out that the forgotten medicine may inhibit a range of viruses via an unrelated mechanism.

The platform was tasked with finding a drug that could block a viral enzyme called RNA-dependent RNA polymerase, which many viruses use to copy their genomes and replicate .

Why This Matters

This could have implications for future research in this area.

Scientists and researchers are watching this development closely.
