8-K: Korro Bio Announces First Regulatory Filing for KRRO-110 and Formation of Clinical Advisory Board

Korro Bio has submitted its first regulatory filing for a Phase 1/2 clinical study of KRRO-110 for Alpha-1 Antitrypsin Deficiency (AATD) and formed a clinical advisory board.

Summary

• Korro Bio has announced the submission of a regulatory filing to the Australian Bellberry Human Research Ethics Committee (HREC) for a Phase 1/2 clinical study of KRRO-110, a treatment for Alpha-1 Antitrypsin Deficiency (AATD).
• The company has also formed a Clinical Advisory Board (CAB) consisting of experts in lung and liver diseases to guide the clinical development of KRRO-110.
• First participant dosing is anticipated in the first quarter of 2025, with an interim data readout expected in the second half of 2025, and completion of the study anticipated in 2026.
• KRRO-110 is an RNA editing oligonucleotide designed to repair a mutation in the SERPINA1 gene, which causes AATD.
• The company believes KRRO-110 has the potential to be a best-in-class therapy due to its differentiated approach to RNA editing.
