Korro Bio is an RNA editing company focused on the discovery and development of a new class of precision genetic medicines for both rare and highly prevalent diseases. RNA editing is a natural physiological process that occurs in cells, including a mechanism mediated by an enzyme called Adenosine Deaminase Acting on RNA (ADAR). Korro Bio’s RNA editing approach involves co-opting this endogenous editing system via a proprietary engineered oligonucleotide to introduce precise edits to RNA. This unique technology enables the development of therapeutic candidates that deliver the functional benefits of gene therapy with a transient, titratable and specific treatment regimen, offering the potential to advance genetic medicines beyond rare genetic diseases into larger patient populations with common diseases. 

Korro Bio merged with Frequency Therapeutics on Jul 14th 2023.
