mRNA-delivered Cas13 treatment for multiple lung viruses

mRNA-encoded Cas13 as a pan-respiratory antiviral

NIH-funded research Emory University · NIH-11248356

This project is developing an inhaled mRNA therapy that uses Cas13 to destroy the RNA of RSV, influenza, and SARS-CoV-2 in the lungs for people at risk of these infections.

What this research studies

This work is creating an inhaled medicine made from synthetic mRNA that tells cells to make Cas13, a programmable enzyme that cuts up viral RNA. The team programs Cas13 to target key RNA sequences from RSV, influenza, and SARS‑CoV‑2 and is optimizing a nebulizer to deliver the mRNA to the lungs. They have shown proof-of-concept in laboratory and animal experiments and are refining safety, dosing, and delivery for future human testing. The goal is a single, broad antiviral that works across common respiratory viruses.

Who could benefit from this research

Good fit: Ideal candidates would include people with or recently exposed to RSV, influenza, or COVID-19 who are eligible for enrollment in future clinical trials testing inhaled Cas13 therapies.

Not a fit: People with non-RNA respiratory conditions, those who cannot use inhaled treatments, or those with allergies to components of mRNA formulations may not benefit from this approach.

Why it matters

Potential benefit: If successful, this could become a single inhaled treatment that quickly lowers virus levels and reduces severe illness from several common respiratory viruses.

How similar studies have performed: Related lab and animal studies, including early work by this team using nebulizer delivery, have shown proof-of-concept, but human safety and effectiveness remain untested.
