Description

Korro Bio, Inc. is a biopharmaceutical company. The Company discovers, develops, and commercializes genetic medicines based on editing ribonucleic acid (RNA), enabling treatment of both rare and highly prevalent diseases. The Company is generating a portfolio of differentiated programs that are designed to harness the bodys natural RNA editing process to effect a precise yet transient single base edit. By editing RNA instead of DNA, it is expanding the reach of genetic medicines. Its Oligonucleotide Promoted Editing of RNA (OPERA) is a foundational platform for RNA editing, which is designed to edit RNA in vivo by delivering an oligonucleotide guide that can target specific RNA sequences. The Companys first development candidate, KRRO-110, is in development as a potential treatment for Alpha-1 Antitrypsin Deficiency (AATD), that has the potential to be disease-modifying and provide a differentiated therapeutic option.
