(Nasdaq: MGX) (the \u201cCompany\u201d), an in vivo genome editing company capitalizing on its proprietary technologies to create curative genetic medicines for patients, today announced a publication in\u00a0<em>Nature Structural &amp; Molecular Biology<\/em> highlighting the discovery and detailed characterization of MG119-28, a compact CRISPR nuclease with superior editing efficiency relative to previously identified compact nucleases.<\/p>\n<p align=\"justify\">The publication, titled \u201c<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=hpv4pcUnJ17wfbezcfZzh6x7VOi0S-pr8-11eGF4wdB6jhrDNpGI5N7dhfUyT-CpVxhp0rPERqfXzGck4W38Agp7SGyV7iv3VE6ArbT0N0gzV2KnysZGQlQzu5NUWyypiRj4Y1PiLuleeFvudpd7ukRqYiPxUqQh1cOgTn-RwGuuTIGVRvUpGpZxPtMoUcTHz3Z3pMyVSfw59RYKMBCDyNaIqp4KgspPbLqxrgVUUGFy-xM4O9emqDGOC415APJKfFiUvM1O4QFPgoqVgK4V2g==\" rel=\"nofollow\" target=\"_blank\"><em>Comparative characterization of Cas12f orthologs reveals mechanistic features underlying enhanced genome editing efficiency<\/em><\/a><em>\u201d<\/em> highlights the potential of MG119-28 (formally named Al3Cas12f) to overcome low editing efficiency in mammalian systems of previously identified compact nucleases from the Cas12f class.<\/p>\n<p align=\"justify\">The publication demonstrates that the enhanced editing performance is due to superior structural stability of the protein and inherently more stable guide RNA which enables faster DNA cleavage activity. The structural and mechanistic insights enabled engineering of MG119-28 to further improve activity across multiple target genes.<\/p>\n<p align=\"justify\">\u201cThe ability to pair compact size with high editing efficiency has been a longstanding challenge in the field,\u201d said Jian Irish, Ph.D., M.B.A., President and Chief Executive Officer of the Company. \u201cThese findings support a path toward building clinically relevant genome editing systems that are both deliverable to tissues outside of the liver via AAV and capable of achieving the levels of activity needed for therapeutic impact. We believe that MG119-28 represents an important step forward for future applications of our platform and the broader field of in vivo gene editing.\u201d<\/p>\n<p align=\"justify\">This most recent study was conducted in collaboration with researchers from the University of Texas at Austin. It builds on the elegant in vivo proof of concept for MG119-28 presented at the ASGCT meeting in 2025 in which the Company demonstrated 64% knockdown of Atxn2 protein in mice after direct injection of a single AAV delivering MG119-28 and a targeting guide. The Company views this data as encouraging as it explores opportunities to advance its gene editing beyond hepatic indications to treat unmet medical needs in neuromuscular disease targets.<\/p>\n<p align=\"justify\">\n        <strong>About Metagenomi Therapeutics, Inc.<\/strong>\n      <\/p>\n<p align=\"justify\">Metagenomi Therapeutics, Inc. is an in vivo genome editing company capitalizing on its proprietary technologies to create curative genetic medicines for patients. The Company was founded on the science of metagenomics, the study of genetic materials recovered from the natural environment, to discover and develop a suite of novel editing tools potentially capable of correcting any type of genetic mutation found anywhere in the human genome. The Company focuses on high value programs in disease indications with well-understood biology and clearly defined clinical development and regulatory pathways. Going forward, the Company intends to continue to expand its pipeline by leveraging its proprietary genetic editing capabilities in site specific deletion, integration and correction.<\/p>\n<p align=\"justify\">MGX-001, the Company\u2019s lead, wholly-owned development program in hemophilia A, has demonstrated a preclinical profile potentially competitive with best-in-class treatment options, including targeted genome editing and durable gene expression in a one-time treatment. MGX-001 is designed to provide curative, life-long protection from bleeding events and joint damage in adults and children with hemophilia A. The Company is also currently pursuing other secreted protein deficiencies leveraging the MGX-001 site-specific genome integration system and partnered assets targeting cardiometabolic diseases.
