Business
Korro Bio, Inc. (KRRO) is a clinical-stage biopharmaceutical company that discovers, develops and commercializes genetic medicines utilizing its proprietary Oligonucleotide Promoted Editing of RNA (OPERA) platform to deliver precise, transient single-base RNA edits for rare and prevalent diseases targeting the liver and central nervous system. The company offers RNA editing oligonucleotides including its lead candidate KRRO-110, an intravenously delivered lipid nanoparticle-formulated therapy in Phase 1/2 clinical trials repairing the SERPINA1 Z mutation to restore normal alpha-1 antitrypsin (AAT) protein levels for alpha-1 antitrypsin deficiency (AATD) affecting liver and lung; KRRO-121, a GalNAc-conjugated oligonucleotide in preclinical development generating a stabilized enzyme variant for urea cycle disorders and hepatic encephalopathy; a subcutaneous GalNAc program in preclinical development also targeting the SERPINA1 gene for AATD; proprietary oligonucleotides in discovery/preclinical stages targeting TAR DNA-binding protein 43 (TDP-43) mRNA to disrupt aggregation in amyotrophic lateral sclerosis (ALS); and oligonucleotides selectively modulating NaV1.7 ion channels for subsets of chronic pain as non-opioid therapeutics. Korro Bio, founded in 2018, maintains headquarters in Cambridge, Massachusetts, and operates primarily in the United States with a focus on genetically validated targets in patient populations underserved by existing therapies. Recent developments include a September 2024 collaboration with Novo Nordisk A/S providing up to $530 million in upfront, milestone and royalty payments for two preclinical cardiometabolic programs advanced by Korro prior to potential handover, placed on 12-month hold in November 2025 alongside a 34% workforce reduction and chief medical officer resignation; a 2024 all-stock merger with Frequency Therapeutics enabling Nasdaq listing under KRRO; and a $116 million Series B financing to support pipeline advancement.
