(Korro) (Nasdaq: KRRO), a biopharmaceutical company focused on developing a new class of genetic medicines based on editing RNA for both rare and highly prevalent diseases, today announced that it has received approval from the Australian Bellberry Human Research Ethics Committee (HREC) and clearance from the Australian Therapeutic Goods Administration (TGA) to initiate a Phase 1/2a clinical study of KRRO-110 for Alpha-1 Antitrypsin Deficiency (AATD). “We are thrilled to receive approval to proceed with our clinical study in Australia,” said Kemi Olugemo, MD, Chief Medical Officer at Korro. “Multiple dose treatment with KRRO-110 in a human transgenic mouse model of PiZZ genotype achieved greater than 60% editing and resulted in secretion of functional M-AAT at therapeutically relevant levels. This approval allows us to demonstrate the potential of KRRO-110 in patients with the PiZZ genotype who remain at risk for serious lung and liver complications despite receiving standard-of-care treatment.” About REWRITE REWRITE is a two-part single and multiple dose-escalating study that will evaluate the safety and tolerability of KRRO-110 in up to 64 participants, including healthy adults and clinically stable AATD patients with the PiZZ genotype. Secondary and exploratory endpoints include pharmacokinetic and pharmacodynamic parameters that will guide optimal dose selection for later stage studies. Korro expects to dose the first participant in the first quarter of 2025, and completion of the study is expected in 2026. An interim readout in PiZZ participants is anticipated in the second half of 2025. For additional information about the REWRITE study, visit ClinicalTrials.gov (NCT06677307). About Alpha-1 Antitrypsin Deficiency (AATD) and KRRO-110AATD is a genetic disorder most commonly caused by a single missense mutation (G-to-A) in the SERPINA1 gene. Affected adult individuals experience pulmonary emphysema and/or hepatic cirrhosis, as well as end organ mani...
