  Content	Precision BioSciences, Inc. (Nasdaq: DTIL), a clinical stage gene editing company utilizing its novel proprietary ARCUS® platform to develop in vivo gene editing therapies for sophisticated gene edits, including gene insertion, excision, and elimination, today announced that its partner iECURE has reported clinical efficacy and safety data in the first patient dosed with ECUR-506 in the Phase 1/2 OTC-HOPE study. ECUR-506 is iECURE's in vivo gene insertion program designed to treat neonatal onset Ornithine Transcarbamylase (OTC) deficiency utilizing a PCSK9-specific ARCUS nuclease, licensed from Precision, that enables insertion of a functional copy of the OTC gene. “Congratulations to iECURE for these exciting results and initial clinical validation in the first infant dosed in their OTC-HOPE trial. These results showcase that a complete clinical response can be achieved through in vivo gene editing for children born with this devastating genetic disease,” said Michael Amoroso, Chief Executive Officer of Precision BioSciences. “The data increases our confidence in the therapeutic potential of ARCUS as a novel in vivo gene editing approach for patients who have been and plan to be treated in clinical trials by Precision and partners.” Treatment with ECUR-506, which employs an ARCUS® nuclease licensed from Precision BioSciences, was generally well tolerated in this infant with no significant clinical safety concerns apart from asymptomatic transaminitis at four weeks. The asymptomatic transaminitis was managed with immunosuppressive therapy and resolved within four weeks. Twelve weeks after a single dose of ECUR-506, ammonia scavenger medication was discontinued and mean daily protein intake was increased to age-appropriate levels. Protein liberalization was well tolerated, and the subsequent mean ammonia level remained within normal limits and was reduced compared to the mean pretreatment level. The response was maintained through six months and indicates that a complete response was achieved in this patient. The OTC-HOPE study is ongoing in the United Kingdom, the United States, Australia, and Spain, and iECURE expects to finish enrollment in 2025 and provide complete data for the program in the first half of 2026. Precision's ELIMINATE-B trial for PBGENE-HBV is ongoing in chronic hepatitis B in Moldova, Hong Kong and New Zealand with Phase 1 data expected in 2025. About Precision BioSciences, Inc. Precision BioSciences, Inc. is a clinical stage gene editing company dedicated to improving life (DTIL) with its novel and proprietary ARCUS® genome editing platform that differs from other technologies in the way it cuts, its smaller size, and its simpler structure. Key capabilities and differentiating characteristics may enable ARCUS nucleases to drive more intended, defined therapeutic outcomes. Using ARCUS, Precision's pipeline is comprised of in vivo gene editing candidates designed to deliver lasting cures for the broadest range of genetic and infectious diseases such as chronic hepatitis B where no adequate treatments exist. About ECUR-506 iECURE's approach to gene editing for its initial programs, including OTC deficiency, relies on the delivery of two adeno-associated virus (AAV) vectors, each carrying different payloads. ECUR-506 comprises two vectors, an ARCUS® nuclease vector targeting gene editing in the well-characterized PCSK9 gene locus and a donor vector that inserts the desired functional OTC gene. iECURE has licensed the ARCUS nuclease for ECUR-506 from Precision BioSciences. The cut in the PCSK9 site serves as the insertion site for the OTC gene, providing a potential path to permanent expression of a functional gene. ECUR-506 is being studied in the OTC-HOPE study, the first clinical ARCUS-based in vivo gene insertion program. About the OTC-HOPE Study The OTC-HOPE study is a Phase 1/2 first-in-human clinical trial of ECUR-506 in baby boys with genetically confirmed neonatal onset OTC deficiency and will test multiple dose levels of ECUR-506. The study is enrolling newborn males up to seven months of age at screening who are diagnosed with severe neonatal onset OTC deficiency and meet certain other criteria. The primary objective is to assess the safety and tolerability of intravenous administration of a single dose of ECUR-506. It will also assess the pharmacokinetics and efficacy of ECUR-506 administration and the potential effects of ECUR-506 on disease-specific biologic markers, developmental milestones and quality of life. The main study will occur in a series of stages over a 10-month period, including screening, stabilization, dosing eligibility, study drug administration, and six-month follow-up. Upon completion of the OTC-HOPE study, participants transition to the 14.5 year long term follow up study (ECUR-LTFU). For more information, visit https://OTC-HOPE.com About OTC Deficiency OTC deficiency, the most common urea cycle disorder, is an inherited metabolic disorder caused by a genetic defect in a liver enzyme responsible for the detoxification of ammonia. Individuals with OTC deficiency can build up excessive levels of ammonia in their blood potentially resulting in devastating consequences, including irreversible neurological damage, coma and death. The severe form of the condition emerges shortly after birth and is more common in boys than girls. The only corrective treatment for early onset severe OTC deficiency is a liver transplant. Currently available medical therapies do not correct the disease and do not eliminate the risk of life-threatening symptoms or crises. About iECURE iECURE is a clinical-stage gene editing company focused on developing therapies that utilize mutation-agnostic in vivo gene insertion for the treatment of liver disorders with significant unmet need. iECURE believes their approach has the potential to restore the function of a dysfunctional gene, regardless of mutation, by knocking-in a functional copy of that gene to offer durable gene expression and long-term, potentially curative, therapeutic benefit. iECURE's management team has extensive experience in executing global orphan drug and gene therapy clinical trials and successfully commercializing multiple products. iECURE intends to leverage their team's core strength in research and development strategy to identify what they believe to be the most suitable target and modality for their product candidates to address particular liver diseases.
