Korro Bio, Inc. Selects Krro-111 As Development Candidate For The Potential Treatment Of Alpha-1 Antitrypsin Deficiency Korro Bio, Inc. announced the addition of KRRO-111 for the potential treatment of AATD to its pipeline of therapeutic programs in development. KRRO-111 is a proprietary GalNAc-conjugated oligonucleotide that is delivered subcutaneously to the liver cells, where it is engineered to co-opt the hepatocytes’ endogenous Adenosine Deaminase Acting on RNA (ADAR) enzyme and repair a pathogenic single nucleotide variant (SNV) on AAT mRNA to restore production of normal AAT protein. This therapeutic profile along with KRRO-111’s rapid onset of action and titratable dosing to treat this disorder, position the compound as a potential best-in-class candidate. AATD is a genetic disorder most commonly caused by a single missense mutation (G-to-A) in the SERPINA1 gene. Affected adults experience pulmonary emphysema and/or hepatic cirrhosis, as well as end organ manifestations. Greater than 95% of severe clinical cases of AATD are homozygous for the PiZ mutation (known as the PiZZ genotype). There are an estimated 3,400,000 individuals with deficiency allele combinations worldwide. The only current FDA-approved treatment for AATD is augmentation therapy, a once-weekly infusion of pooled human plasma-derived AAT protein, which does not adequately address the manifestations of AATD. In preclinical studies, KRRO-111 demonstrated best-in-class RNA editing where >90% of the AAT transcripts in the liver cells have been corrected, translating into ~90% M-AAT protein. In a repeat-dose study, KRRO-111 (3 mg/kg) was administered to PiZZ mice with a loading phase followed by dosing once every two weeks. KRRO-111 nearly eliminated active Z protein production, reducing non-inclusion Z-AAT by ~95% versus vehicle at both days 28 and 56, reflecting near-complete cessation of Z protein synthesis across the hepatocyte population. Pre-existing aggregates were progressively cleared, with inclusion-associated Z-AAT significantly reduced by approximately 69% at day 28, consistent with autophagic clearance of accumulated protein following successful editing; the residual burden reflects pre-existing disease rather than incomplete editing. By simultaneously increasing circulating M-AAT protein and decreasing pathogenic Z-AAT aggregates in the lung, KRRO-111 has the potential to improve both lung and liver manifestations of the disease. The Company plans to present additional data from its KRRO-111 program at a future scientific meeting or Company-hosted event. Major Estimate Revision • May 14

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 54% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Earnings are forecast to decline by an average of 9.8% per year for the foreseeable future. Shareholders have been substantially diluted in the past year (54% increase in shares outstanding). Minor Risk Currently unprofitable and not forecast to become profitable over next 3 years (US$108m net loss in 3 years). Aankondiging • Mar 09
