Korro Bio CEO: KRRO-121 Expected Regulatory Filing in H2 2026
"The first quarter marked significant scientific progress for Korro as we continued to advance our OPERA platform and build a pipeline of differentiated RNA editing medicines," commented Ram Aiyar, Chief Executive Officer and President of Korro Bio. "Our lead program, KRRO-121, remains on track for its regulatory filing in the second half of 2026, bringing us closer to delivering a potential first-in-class treatment for patients suffering from hyperammonemia in urea cycle disorders and hepatic encephalopathy. At the same time, our GalNAc-conjugated program for alpha-1 antitrypsin deficiency achieved greater than 90% in vivo RNA editing, a result that reinforces the broad therapeutic potential of the OPERA platform and the first demonstration that close to 100% of RNA can be edited with an oligonucleotide. We are well capitalized following our oversubscribed private placement, which provides us with the resources to reach meaningful clinical milestones across multiple programs. On behalf of the entire Korro team, I wish to extend gratitude to all Korro stakeholders for their belief in the potential of our novel RNA editing platform to transform the treatment of debilitating diseases."
